1 2000-01-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3 * eval.c (SCM_CEVAL): Reverse order of
4 scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
5 (Thanks to Brad Knotwell.)
7 Mon Jan 3 08:30:02 2000 Greg Harvey <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
9 * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
12 * pairs.h: Added a comment about the need for the SCM_SETCAR in
15 Mon Jan 3 08:25:19 2000 Greg J. Badros <gjb@cs.washington.edu>
17 * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
18 SCM_NIMP tests that were redundant are now eliminated. Patches
19 from Dirk Hermann applied by hand.
21 1999-12-28 Gary Houston <ghouston@arglist.com>
23 * posix.c (scm_waitpid): move the HAVE_WAITPID test out of the
24 procedure body, so that the procedure is left undefined if waitpid
25 is not available. previously in this case the procedure was
26 defined but would raise a system-error when called, which is
27 pointless. I intend to make the same change for other procedures
28 and deprecate SCM_SYSMISSING and scm_sysmissing.
30 1999-12-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
32 * feature.c (s_scm_add_hook_x): Call scm_wrong_type_arg instead of
33 scm_misc_error when add-hook! is passed a procedure of wring
34 arity. (Thanks to Greg Harvey.)
36 1999-12-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
38 * macros.c (scm_make_synt): Use scm_make_subr_opt to make the
39 transformer subr. (Thanks to Bill Schottstaedt.)
41 1999-12-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
43 * objects.c (scm_class_of): Bugfix: Inserted missing SCM_CDR
44 setting struct table class.
46 Sun Dec 19 10:22:34 1999 Greg J. Badros <gjb@cs.washington.edu>
48 * threads.c, mit-pthreads.c, list.c, coop.c: Remove K&R
49 prototypes; just use ANSI C prototypes. I'm not sure how
50 mit-pthreads.c ever compiled -- it still doesn't for me, but the
51 normal make procedure does not try to build it anyway (even
52 --with-threads I get the other threads code building) so I'm not
55 Sat Dec 18 16:58:34 1999 Greg J. Badros <gjb@cs.washington.edu>
57 * tags.h (SCM_CONSP, SCM_NCONSP): Define these in terms of
58 SCM_SLOPPY_CONSP and SCM_SLOPPY_NCONSP. (SCM_CONSP) Define this
59 in terms of SCM_SLOPPY_NCONSP instead of repeating the
62 * symbols.h (SCM_SLOPPY_SUBSTRP, SCM_SUBSTRP): Added former, and
63 define latter in terms of sloppy variant.
65 * strings.h (SCM_SLOPPY_STRINGP, SCM_STRINGP): Added former, and
66 define latter in terms of sloppy variant.
68 * scm_validate.h (SCM_MAKE_VALIDATE): Added this macro to factor
69 out the commonality of the various basic SCM_VALIDATE_foop
70 macros. Use SCM_MAKE_VALIDATE macro where possible. Fix
71 SCM_VALIDATE_INT_COPY to not use scm_num2ulong -- that does
72 coercion to an integer which is more advanced than desired and
73 SCM_NUM2ULONG provides that functionality. Use SCM_ASSERT_RANGE
74 appropriately for the various _MIN, _MAX, _RANGE macros. Drop
75 some superfluous "SCM_NIMP &&" where possible. Eliminate obsoleted
76 SCM_VALIDATE_NIMCONS (SCM_VALIDATE_CONS now does the NIMP test as
77 part of its SCM_CONSP test).
79 * socket.c, ports.c, pairs.c, list.c, lang.c, async.c: Use
80 SCM_VALIDATE_CONS, not obsoleted SCM_VALIDATE_NIMCONS.
82 Sat Dec 18 15:33:05 1999 Greg J. Badros <gjb@cs.washington.edu>
84 * dynl.c: Added #include "scm_validate.h"
86 Sat Dec 18 15:22:10 1999 Greg J. Badros <gjb@cs.washington.edu>
88 * alist.c, chars.c, dynl.c, net_db.c, numbers.c, unif.c: Use
89 SCM_NUM2ULONG instead of scm_num2ulong; SCM_NUM2LONG instead of
90 scm_num2long; SCM_WTA instead of scm_wta. Only done for when
91 FUNC_NAME was used as an argument of the macro and the formal
92 argument name was the explicit argument in the old function call.
93 These were just missed in my first pass of changes.
95 1999-12-18 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
97 * guile-doc-snarf.in (filename): Strip path to source dir before
98 touching the .x-files.
100 1999-12-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
102 * debug.c (scm_reverse_lookup): Bugfix: Reinserted SCM_NIMP.
104 * eval.c (SCM_CEVAL): Removed check for unbound slot in
105 SCM_IM_SLOT_REF. (This is now handled in a smarter way in GOOPS.)
107 1999-12-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
109 * tags.h (SCM_SLOPPY_NCONSP, SCM_SLOPPY_CONSP): New macros.
110 (SCM_ECONSP): Version which doesn't mix && and || without
112 (SCM_NECONSP): Bugfree version.
114 Fri Dec 17 12:09:11 1999 Greg J. Badros <gjb@cs.washington.edu>
116 * tags.h (SCM_ECONSP, SCM_NECONSP): Fix these macros to have the
117 SCM_NIMP test integrated into an || clause that I'd missed before
118 and was causing a segfault in the regression tests.
120 * symbols.h (SCM_ROUCHARS): Make cast be to (unsigned char *), not
121 (char *); fixes a problem reported by the regression test
124 * ports.c: Fixed a couple of arg/number mismatches in
125 SCM_VALIDATE_ macros.
127 Now passes the (not-comprehensive) guile-modules test-suite again!
129 Thu Dec 16 12:41:22 1999 Greg J. Badros <gjb@cs.washington.edu>
131 * coop-threads.c: Remove K&R function headers.
133 * scm_validate.h: Added SCM_VALIDATE_THREAD.
135 * *.c: Remove SCM_NIMP(X) when it is an extraneous pre-test given
136 that SCM_FOOP macros all now include SCM_NIMP in their expansion.
137 This simplifies lots of code, making it far more readable.
139 Wed Dec 15 19:45:14 1999 Greg J. Badros <gjb@cs.washington.edu>
141 * *.h: Use SCM_NIMP(X) && in all the FOOP macros.
143 * *.[ch]: Use do { ... } while (0) idiom in macros that expanded
146 Tue Dec 14 10:53:14 1999 Greg J. Badros <gjb@cs.washington.edu>
148 * snarf.h: Put SCM_PROC and SCM_PROC1 back in for
149 backward-compatibility of packages that use Guile. Internally
150 Guile should not use them, though. (Maybe enforce this with a new
151 -DBUILDING_GUILE compile-time flag?).
153 Tue Dec 14 09:41:01 1999 Greg J. Badros <gjb@cs.washington.edu>
155 * backtrace.c (scm_set_print_params_x): Renamed from
158 * guile-doc-snarf.in: Use guile-snarf.awk, not
159 guile-doc-snarf.awk. Pass the basename of $filename
161 * load.h: Added prototypes for scm_sys_library_dir,
164 * load.c (scm_sys_library_dir, scm_sys_site_dir): Added these
165 functions, and took out the old scm_library_dir, scm_site_dir,
166 scm_pkgdata_dir. Now the primitives are %package-data-dir
167 (already existed), %library-dir, and %site-dir.
169 * debug.c: Use SCM_MISC_ERROR when possible instead of using
170 s_scm_* in a scm_misc_error() call.
172 * Makefile.am: Use guile-snarf.awk, not guile-doc-snarf.awk. Make
173 using guile-doc-snarf send stdout to $@ to create the .x file like
176 * guile-snarf.awk.in: Added.
178 * guile-doc-snarf.awk.in: Removed (sorry to back out a recent
179 commit; if we're going to switch to guile-snarf I figure it makes
180 sense to get this right now-- I'd already had the change in my
181 working copy when the below commit happened).
183 1999-12-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
185 * guile-doc-snarf.awk: Removed.
187 * guile-doc-snarf.awk.in: Added.
189 * ports.c (s_scm_pt_member): Fixed validation.
191 * guile-doc-snarf.in (filename): Use basename in order to strip
194 * debug.c (scm_make_iloc, s_scm_proc_to_mem): Added missing
196 (scm_memcons, scm_memcons, mem_to_proc): Renamed function name
199 * backtrace.c (set_print_params_x): Fixed GUILE_PROC macro.
201 * tags.h (SCM_UNBOUND): New iflag which is needed for some time to
202 mark the unboundness of a GOOPS slot. (Added now in order to
203 correct a oversight. Should probably be removed again and
204 replaced with SCM_UNDEFINED when the corresponding code in GOOPS
207 * print.c (scm_isymnames): Added printed representation for
210 * eval.c (SCM_CEVAL): Bugfix: Added check for unbound slot in
213 Mon Dec 13 17:23:22 1999 Greg J. Badros <gjb@cs.washington.edu>
215 * strings.c: Fixed mistaken default value in
216 scm_make_shared_substring; thanks Eric Moore!
218 Mon Dec 13 16:29:13 1999 Greg J. Badros <gjb@cs.washington.edu>
220 * guile-doc-snarf.awk: Use sub instead of gsub in ^ anchored
221 replacement for docstrings. Fixes problem Ryan Yeske observed
222 with using mawk on his system. Thanks Ryan!
224 Mon Dec 13 13:30:06 1999 Greg J. Badros <gjb@cs.washington.edu>
226 * guile-doc-snarf.in: Do not echo to stdout since the output now
227 gets stuck directly in the files instead of redirected from
230 * guile-doc-snarf.awk: Escape a literal ) -- thanks Ryan
231 Yeske. Use print instead of printf to prime the .x file since
232 AIX's cpp has problems with #include-ing empty files (according to
233 the old guile-snarf.in file).
235 Sun Dec 12 19:39:00 1999 Greg J. Badros <gjb@cs.washington.edu>
237 * Makefile.am: Fix ETAGS_ARGS to recognize GUILE_PROC,
238 GUILE_PROC1. Build guile-procedures.txt, and add that file to
241 * load.c: Added `pkgdata-dir', `site-dir', `library-dir'
244 * guile-doc-snarf.awk: Drop trailing space when no arguments:
245 e.g., "(foo )" is now "(foo)".
247 * *.c, alist.c: moved all the documentation for primitives from
248 guile-doc/ref/{appendices,posix,scheme}.texi into the source code.
249 This leaves about half of the primitives undocumented. Also, all
250 the markup is currently still texinfo. I don't have a problem
251 with texinfo per se, but the markup is not very descriptive or
254 Sun Dec 12 16:50:26 1999 Greg J. Badros <gjb@cs.washington.edu>
256 * scm_validate.h: Drop the SCM_DOCSTRING_SNARF for turning off
257 SCM_VALIDATE macros; the SCM_VALIDATE macros should be checked for
258 argument mismatches (along with the FUNC_NAME macro checking) by a
259 static tool that runs directly over the .c files.
261 * snarf.h: Handle SCM_REGISTER_PROC better when snarfing. The
262 docstring is still missing from the .doc file; it just gives the
263 name of the C function that gets called instead.
265 * guile-doc-snarf.awk: Be sure to touch the output files to help
266 make out. Also handle SCM_REGISTER_PROC better, and change the
267 output format slightly.
269 Sun Dec 12 15:33:40 1999 Greg J. Badros <gjb@cs.washington.edu>
271 * snarf.h: Drop SCM_PROC, SCM_PROC1. Added extra output for
272 guile-doc-snarf script.
274 * guile-doc-snarf.in, guile-doc-snarf.awk: New, simple doc
275 extraction system. Builds foo.x, foo.doc from foo.{c,cc}.
276 There are dependencies between these files and snarf.h. This
277 replaces guile-snarf.
279 * guile-snarf.in: Drop everything after $$$ for the new snarf.h
280 macros. This is obsoleted by guile-doc-snarf, but kept here for
281 now for good measure.
283 * Makefile.am: Added guile-doc-snarf, guile-doc-snarf.awk to
284 bin_SCRIPTS. Added .doc to SUFFIXES, and give rule for creating
285 .doc files to use guile-doc-snarf. Update the rule for creating
286 .x files to use guile-doc-snarf.
288 Sun Dec 12 12:31:38 1999 Greg J. Badros <gjb@cs.washington.edu>
290 * *.c: Finish replacing K&R style prototypes with ANSI C
293 * eval.c: Make scm_m_mody's 3rd argument be a const char *, not a
294 char *. ANSI prototypes caught this.
296 * strorder.c: Use GUILE_PROC1 for the couple SCM_PROC1 expansions
299 * scm_validate.h: Use SCM_BOOLP for validating bools. Do not
300 expand macros if SCM_DOCSTRING_SNARF.
302 Sun Dec 12 11:23:22 1999 Greg J. Badros <gjb@cs.washington.edu>
304 * *.c, srcprop.h: Use SCM_BOOL(f) instead of (f? SCM_BOOL_T:
305 SCM_BOOL_F) and use SCM_NEGATE_BOOL(f) instead of (f? SCM_BOOL_F:
308 Sun Dec 12 11:08:51 1999 Greg J. Badros <gjb@cs.washington.edu>
310 * boolean.h: Added SCM_BOOL, SCM_NEGATE_BOOL, SCM_BOOLP to here,
313 * scm_validate.h: Moved above out into boolean.h, fix typo in
314 SCM_VALIDATE_NIM macro.
316 Sun Dec 12 10:29:12 1999 Greg J. Badros <gjb@cs.washington.edu>
318 * *.c, scm_validate.h: Use SCM_VALIDATE_NIM, not SCM_VALIDATE_NIMP
319 (none of the other validate macros have the trailing P).
321 Sun Dec 12 10:07:29 1999 Greg J. Badros <gjb@cs.washington.edu>
323 * scm_validate.h: Added the FSF copyright to the top.
325 * strings.c: Use SCM_ASSERT_RANGE in a couple of places instead of
326 SCM_ASSERT w/ SCM_OUT_OF_RANGE.
328 Sat Dec 11 18:34:12 1999 Greg J. Badros <gjb@cs.washington.edu>
330 * Makefile.am: Added scm_validate.h to modinclude_HEADERS.
332 * *.c: Pervasive software-engineering-motivated rewrite of
333 function headers and argument checking. Switched SCM_PROC,
334 SCM_PROC1 macros to be GUILE_PROC, GUILE_PROC1 (may change names
335 later, but was useful to keep old versions around while migrate)
336 that has docstrings and argument lists embedded in the GUILE_PROC
337 macro invocations that expand into a function header. Use lots of
338 new SCM_VALIDATE_* macros to simplify error checking and reduce
339 tons of redundancy. This is very similar to what I did for Scwm.
341 Note that none of the extraction of the docstrings, nor software
342 engineering checks of Scwm is yet added to Guile. I'll work on
343 that tomorrow, I expect.
345 * chars.c: Added docstrings for the primitives defined in here.
347 * snarf.h: Added GUILE_PROC, GUILE_PROC1. Added
348 SCM_REGISTER_PROC to be like old SCM_PROC, though old SCM_PROC
349 still remains for now. Changed naming convention for the s_foo
350 string name of the primitive to be s_scm_foo for ease of use with
353 * scm_validate.h: Lots of new SCM_VALIDATE macros to simplify
354 argument checking through guile. Maybe some of these should be
355 folded into the header file for the types they check, but for now
356 it was easiest to just stick them all in one place.
358 1999-12-10 Greg Harvey <Greg.Harvey@thezone.net> (applied --12/10/99 gjb)
360 * smob.c (scm_smob_prehistory): initialize allocated smob
362 * tags.h: new tag: scm_tc16_allocated
364 * gc.c (scm_gc_for_newcell): set the car of the new cell
365 to scm_tc16_allocated
366 * pairs.h (SCM_NEWCELL): set the car to scm_tc16_allocated
367 (scm_gc_mark): mark allocated cells.
369 1999-12-09 Greg J. Badros <gjb@cs.washington.edu>
371 * strports.h, strports.c (scm_eval_0str): Fix constness. Some
372 thanks to Dirk Hermann.
374 * gh_eval.c (gh_eval_str, gh_eval_file, gh_eval_str_with_catch,
375 gh_eval_str_with_standard_handler,
376 gh_eval_str_with_stack_saving_handler): Fix constness. Some
377 thanks to Dirk Hermann.
379 * gh_data.c (gh_str02scm): Fix constness.
381 * gh.h: Fix constness of prototypes for the above.
383 * vectors.c: Include "unif.h" to avoid a warning about missing
384 prototype for scm_uniform_element_size().
386 1999-12-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
388 * vectors.c (scm_vector_length, scm_vector_ref, scm_vector_set_x):
389 Turned into primitive generics.
391 1999-12-04 Gary Houston <ghouston@freewire.co.uk>
393 * ports.c (scm_port_closed_p): new procedure, implements
394 "port-closed?" suggested by Bernard Urban.
395 ports.h: added prototype, removed the SCM_P macros.
397 1999-11-30 Gary Houston <ghouston@freewire.co.uk>
399 * unif.h: added some comments, removed the SCM_P macros.
401 1999-11-29 Gary Houston <ghouston@freewire.co.uk>
403 * vports.c (sf_write): use scm_makfromstr, not scm_makfrom0str
404 (thanks to Daniel Skarda).
406 1999-11-22 Jim Blandy <jimb@savonarola.red-bean.com>
408 * gscm.c, gscm.h: Deleted. They were unused.
410 1999-11-20 Gary Houston <ghouston@freewire.co.uk>
412 * unif.c (scm_list_to_uniform_array): call
413 scm_dimensions_to_uniform_array with a third argument of
414 SCM_UNDEFINED instead of SCM_EOL.
416 1999-11-19 Gary Houston <ghouston@freewire.co.uk>
418 * the following changes allow guile to be built with the array
419 "module" omitted. some of this stuff is just tc7 type support,
420 which wouldn't be needed if uniform array types were converted
423 * tag.c (scm_utag_bvect ... scm_utag_cvect): don't define unless
425 (scm_tag): don't check array types unless HAVE_ARRAYS.
427 * sort.c (scm_restricted_vector_sort_x, scm_sorted_p):
428 remove the unused array types.
429 * (scm_stable_sort, scm_sort): don't support vectors if not
430 HAVE_ARRAYS. a bit excessive.
432 * random.c (vector_scale, vector_sum_squares,
433 scm_random_solid_sphere_x, scm_random_hollow_sphere_x,
434 scm_random_normal_vector_x): don't define unless HAVE_ARRAYS.
436 * gh_data.c (makvect, gh_chars2byvect, gh_shorts2svect,
437 gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect, gh_doubles2dvect,
438 gh_uniform_vector_length, gh_uniform_vector_ref):
439 don't define unless HAVE_ARRAYS.
440 (gh_scm2chars, gh_scm2shorts, gh_scm2longs, gh_scm2floats,
442 don't check vector types if not HAVE_ARRAYS.
444 * eq.c (scm_equal_p), eval.c (SCM_CEVAL), print.c (scm_iprin1),
445 gc.c (scm_gc_mark, scm_gc_sweep), objects.c (scm_class_of):
446 don't support the array types unless HAVE_ARRAYS is defined.
448 * tags.h: make nine tc7 types conditional on HAVE_ARRAYS.
450 * read.c (scm_lreadr): don't check for #* unless HAVE_ARRAYS is
451 defined (this should use read-hash-extend).
453 * ramap.c, unif.c: don't check whether ARRAYS is defined.
455 * vectors.c (scm_vector_set_length_x): moved here from unif.c. call
456 scm_uniform_element_size if HAVE_ARRAYS.
457 vectors.h: prototype too.
459 * unif.c (scm_uniform_element_size): new procedure.
461 * init.c (scm_boot_guile_1): don't call scm_init_ramap or
462 scm_init_unif unless HAVE_ARRAYS is defined.
464 * __scm.h: don't define ARRAYS.
466 * Makefile.am (EXTRA_libguile_la_SOURCES): unif.c and ramap.c
467 moved here from libguile_la_SOURCES.
469 1999-11-18 Gary Houston <ghouston@freewire.co.uk>
471 * socket.c (scm_htons, scm_ntohs, scm_htonl, scm_ntohl): new
472 functions for network data conversion.
474 * numbers.c (scm_num2long, scm_num2longlong):
475 throw out-of-range instead of wrong-type-arg if appropriate.
476 (scm_iint2str): handle -2^31 correctly.
477 (scm_num2long): handle -2^31 bignum correctly.
478 (scm_num2long_long): rewrite the bigdig case: basically copied
480 numbers.h: (SCM_BITSPERLONGLONG): deleted.
482 * unif.c (rapr1): use sprintf instead of intprint for unsigned
483 longs: intprint can't cope with large values.
485 * numbers.c (scm_num2ulong): check more consistently that the
486 input is not negative. if it is, throw out-of-range instead of
489 * ramap.c (scm_array_fill_int): don't limit fill to INUM for
490 uvect, ivect or llvect.
491 Check that fill doesn't overflow short uniform array.
493 * __scm.h: add another long to the definition of long_long and
496 * unif.c (scm_raprin1): use 'l' instead of "long_long" in the
497 print representation of llvect. read can't handle more than
499 (scm_dimensions_to_uniform_array): make "fill" an optional argument
500 instead of a rest argument.
502 * tags.h (scm_tc7_llvect): wasn't defined anywhere, so use the free
505 * __scm.h: don't mention LONGLONGS.
507 * unif.c, numbers.c, eq.c, gc.c, print.c, eval.c, ramap.c:
508 replace LONGLONGS with HAVE_LONG_LONGS as set by configure.
510 1999-11-17 Gary Houston <ghouston@freewire.co.uk>
512 * net_db.c (scm_inet_aton): throw errors using the misc-error key
513 instead of system-error. inet_aton doesn't set errno.
514 system-error isn't right in gethost either, since it's throwing
515 the value of h_errno instead of errno. so:
516 (scm_host_not_found_key, scm_try_again_key,
517 scm_no_recovery_key, scm_no_data_key): new error keys.
518 (scm_resolv_error): new procedure, use the new keys.
519 (scm_gethost): call scm_resolv_error not scm_syserror_msg.
521 1999-11-16 Gary Houston <ghouston@freewire.co.uk>
523 * error.c: (various): use scm_cons instead of scm_listify
524 to build short lists.
526 1999-11-03 Gary Houston <ghouston@freewire.co.uk>
528 * socket.c (scm_fill_sockaddr): zero the address structure before
529 use, in case it has a sin_len field and the OS doesn't like random
530 values (thanks to Bertrand Petit).
532 1999-10-26 Mark Galassi <rosalia@lanl.gov>
534 * gh.h, gh_data.c (gh_symbol2scm): changed gh_symbol2scm() to take
535 a const char * argument, upon suggestion from Lynn Winebarger.
537 1999-10-26 Gary Houston <ghouston@freewire.co.uk>
539 * strports.c (st_end_input): avoid dubious pointer arithmetic.
541 1999-10-24 Gary Houston <ghouston@freewire.co.uk>
543 * Move the responsibility for resetting port buffers from the
544 caller of the ptob seek procedure to the implementation. This
545 gives more control in general to the ptob seek: in particular the
546 change of 1999-10-20 can be made to work without breaking seek on
547 string ports. There's a comment in NEWS about upgrading port
550 * ports.c (scm_seek): don't reset the port buffers here.
552 * fports.c (fport_seek): reset the buffers, except for the
555 * strports.c (st_end_input): (bug fix): decrement pt->read_pos by
556 offset. check that it's not less than read_buf.
557 (st_seek): reset the buffers first, unless it's the 0 SEEK_CUR
558 case and currently reading.
560 1999-10-20 Gary Houston <ghouston@freewire.co.uk>
562 * ports.c (scm_seek): Add a special case for SEEK_CUR, offset 0,
563 so that unread chars are not needlessly discarded. (thanks to
566 1999-10-18 Gary Houston <ghouston@freewire.co.uk>
568 * fports.c (scm_fdes_to_port): always set rw_random if the fdes is
569 random access. rw_active needs to be maintained even for single
570 directional ports, otherwise scm_seek and probably other things are
571 broken. (thanks to Roland Orre).
573 * strports.c (scm_mkstrport): set rw_random to 1 unconditionally.
575 * ports.c (scm_add_to_port_table): initialise rw_random to 0.
577 * ports.h (scm_port): change the comments on rw_random and rw_active.
579 1999-10-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
581 * ioext.c: Added #include "feature.h".
583 These changes turns `delay' into a memoizing macro. This is
584 because it may be expanded before evaluation if it occurs at the
585 beginning of a body. (Thanks to Lauri Alanko.)
587 * eval.c, eval.h (scm_sym_delay): New global symbol.
589 * tags.h (SCM_IM_DELAY): New immediate symbol.
591 * print.c (scm_isymnames): Printed representation.
593 * eval.c (unmemocopy, SCM_CEVAL): Handle SCM_IM_DELAY.
594 (scm_m_delay): Turned into a memoizing macro.
596 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version.
598 1999-10-11 Jim Blandy <jimb@savonarola.red-bean.com>
600 * gh_data.c (gh_ints2scm, gh_doubles2scm): Make sure elements are
601 protected from GC while building the vector. (Thanks to Bernard
602 Urban and Greg Harvey.)
604 1999-10-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
606 * throw.c (handler_message): Display backtrace if backtraces
609 1999-10-05 Jim Blandy <jimb@savonarola.red-bean.com>
611 * Makefile.in, scmconfig.h.in: Deleted from CVS repository. Run
612 the autogen.sh script to create generated files like these.
614 * numbers.c (scm_string_to_number): Signal an error if radix is
615 less than two. (Thanks to Jorgen Schaefer.)
617 * print.c (scm_write, scm_display, scm_newline, scm_write_char):
618 Don't assume that the current output port is valid. Somebody
619 might close it. (Thanks to Bernard Urban.)
621 1999-10-02 Jim Blandy <jimb@zwingli.cygnus.com>
623 * scmconfig.h.in: Regenerated.
625 * Makefile.am (EXTRA_libguile_la_SOURCES): fix typo.
627 Mon Sep 27 17:15:14 1999 Greg J. Badros <gjb@cs.washington.edu>
629 * __scm.h: Fix a bunch of macros that were missing do-while(0)
632 * debug.c, eval.c: Fix buggy uses of SCM_ALLOW_INTS (missing
633 semicolon) exposed by the above change.
635 1999-09-27 Greg J. Badros <gjb@cs.washington.edu>
637 * stacks.c: Avoid compiler warning re: unitialized var.
639 * scmconfig.h.in: Added DEBUG_FREELIST
641 * pairs.h: Fix macro that was not do-while(0) sandwiched.
643 * gc.h, gc.c: Added scm_gc_set_debug_check_freelist_x,
646 1999-09-23 Gary Houston <ghouston@freewire.co.uk>
648 * ioext.c (scm_init_ioext): enable "i/o-extensions" feature here
649 instead of in scm_init_filesys.
651 * init.c (scm_boot_guile_1): don't call scm_init_posix or
652 scm_init_filesys unless HAVE_POSIX is defined.
653 don't call scm_init_netdb or scm_init_socket unless
654 HAVE_NETWORKING is defined.
656 * Makefile.am (EXTRA_libguile_la_SOURCES): filesys.c, posix.c,
657 net_db.c, socket.c: moved here from libguile_la_SOURCES.
659 1999-09-25 Jim Blandy <jimb@savonarola.red-bean.com>
661 * root.c (scm_make_root): Initialize all the fields of the new
662 root. GC could happen any time, you know. (Thanks to Greg
665 * numbers.c (scm_number_to_string): Signal an error if radix is
666 less than two. (Thanks to Jorgen Schaefer.)
668 * Makefile.am (EXTRA_libguile_la_SOURCES): Add memmove.c here,
669 so automake will actually generate rules for it.
670 * Makefile.in: Regenerated.
672 1999-09-21 Jim Blandy <jimb@savonarola.red-bean.com>
674 * backtrace.c: #include "_scm.h" before testing whether
675 HAVE_UNISTD_H is #defined.
677 1999-09-20 Jim Blandy <jimb@savonarola.red-bean.com>
679 * read.c (scm_read): Don't assume that scm_cur_inp is always open.
680 * ports.c (scm_read_char): Same.
681 * ioext.c (scm_read_line): Same.
682 (Thanks to Bernard Urban.)
684 1999-09-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
686 * vectors.c (scm_vector_move_right_x): Bugfix: Remove side effect
688 numbers.c: Removed #ifndef SCM_RECKLESS at places where type
689 checking may invoke a generic. (Thanks to Michael Livshin.)
691 * __scm.h (SCM_WTA_DISPATCH_0, SCM_GASSERT0): New macros.
693 * numbers.c (scm_max, scm_min, scm_sum, scm_difference,
694 scm_product, scm_divide): Bugfix: Don't pass SCM_UNDEFINED to the
695 generic function if the asubr is called with only one arg.
697 1999-09-20 Gary Houston <ghouston@freewire.co.uk>
699 * scmsigs.c (scm_sigaction): add SA_RESTART to flags only if
700 HAVE_RESTARTABLE_SYSCALLS.
701 (scm_init_scmsigs): use siginterrupt if it's available. not
702 everyone who has restartable syscalls has SA_RESTART it seems.
704 (scm_sigaction): use scm_num2long/scm_long2num when converting
705 SIG_DFL/SIG_IGN, in case it doesn't fit in an INUM. use
706 scm_integer_p to test the type.
708 1999-09-18 Gary Houston <ghouston@freewire.co.uk>
710 * _scm.h, scmsigs.c: replace HAVE_RESTARTS with
711 HAVE_RESTARTABLE_SYSCALLS.
713 * strports.c (scm_strport_to_string): create the string from
714 pt->read_buf instead of an expression that evaluates to the
717 * gdbint.c (gdb_print): don't just use SCM_CHARS to get a C string
718 from the port: the port's buffer may not be NUL terminated.
720 1999-09-16 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
722 * Makefile.am (.c.x): Added missing semicolon after `false'.
724 1999-09-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
726 * print.c (scm_iprin1): Turn `write' and `display' into
727 primitive generics and use their associated generic functions in
728 scm_iprin1 for GOOPS objects.
730 * backtrace.c: #include <unistd.h> if present.
732 1999-09-14 Jim Blandy <jimb@savonarola.red-bean.com>
734 * Makefile.am (.c.x): Don't create a subshell just to delete the
735 .x file and return false.
736 * Makefile.in: Regenerated.
738 1999-09-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
740 * feature.c (scm_create_hook): New function. Replaces
741 scm_make_named_hook which is now deprecated.
742 (scm_make_hook_with_name): New primitive.
743 (print_hook): Hooks now print in a fancy way.
745 1999-09-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
747 * __scm.h, backtrace.c, backtrace.h, debug.c, debug.h, dynl-dld.c,
748 dynwind.c, dynwind.h, eval.h, evalext.c, evalext.h, feature.c,
749 feature.h, hashtab.c, hashtab.h, objects.c, objects.h, print.c,
750 procs.c, procs.h, smob.c, smob.h, srcprop.c, strorder.c, struct.c,
751 struct.h: Updated copyright notices.
753 * srcprop.c (scm_source_property): Bugfix: Use SCM_NECONSP instead
754 of SCM_NCONSP. (Thanks to Greg Badros.)
756 * gsubr.c (scm_make_gsubr): Use scm_make_subr_opt for creation of
759 * eval.c, debug.h (SCM_BACKTRACE_WIDTH): New debug option: width.
761 * backtrace.c: Keep backtraces within specified width by
762 adaptively adjusting fancy printing parameters and cut output if
764 (scm_display_application): Check args.
766 1999-09-11 Jim Blandy <jimb@savonarola.red-bean.com>
768 Change the name of the objects returned by OPENDIR from
769 "directory" to "directory stream". A predicate named "directory?"
771 * filesys.c (scm_directory_stream_p): Renamed from scm_directory_p.
772 At the Scheme level, "directory?" -> "directory-stream?".
773 (scm_dir_print): Use the phrase "directory stream" in printed form.
774 * filesys.h (scm_directory_stream_p): Prototype renamed
777 * Makefile.am (CLEANFILES): Remove versiondat.h; that should only
778 be removed by `make distclean', since it's generated by configure.
779 * Makefile.in: Regenerated.
780 (Thanks to Robert Bihlmeyer.)
782 * strop.c (scm_substring_move_x): Signal an error if start1
783 doesn't come before end1. (Thanks to Karoly Lorentey).
785 * numbers.c (scm_istr2flo): Don't call SCM_INEXP without first
786 calling SCM_NIMP. (Thanks to Karoly Lorentey).
788 * version.c (scm_libguile_config_stamp): Deleted. See
789 corresponding change to ../ice-9/boot-9.scm.
790 * versiondat.h.in: Remove definition for GUILE_STAMP.
791 * version.h: Delete prototype.
792 * Makefile.in: Regenerated.
794 1999-09-11 Gary Houston <ghouston@easynet.co.uk>
796 * filesys.c (scm_directory_p): new procedure "directory?" Returns
797 a boolean indicating whether its argument is a directory
798 port as returned by opendir (thanks to Dirk Herrmann for the
801 1999-09-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
803 * backtrace.c (display_frame_expr): Don't print a newline.
804 (display_frame): Print the newline here instead.
805 (display_backtrace_body): Don't print "Backtrace:".
806 (scm_backtrace): Print "Backtrace:" here instead.
808 1999-09-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
810 * procs.c (scm_setter): Signal WTA if handed an entity or operator
813 * feature.c, feature.h: (scm_hook_p, scm_hook_empty_p): New
814 primitives. (Thanks to Greg Badros);
815 (scm_hook_to_list): New primitive; Hooks are now smobs.
817 1999-09-08 Gary Houston <ghouston@easynet.co.uk>
819 * stime.c (bdtime2c): rewrite the ASSERTs. Accept a value
820 of #f for the 10th vector element to avoid an exception
821 seen by Bernard Urban.
822 (scm_mktime): unneeded ASSERT removed.
824 1999-09-07 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
826 * eval.c (scm_map, scm_for_each): Converted to dispatch on generic
829 * __scm.h (SCM_WTA_DISPATCH_n, SCM_GASSERTn): New macros.
831 1999-09-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
833 * numbers.c: Converted comparison operations to dispatch on
834 generic if args don't match.
836 * Makefile.am (ETAGS_ARGS): Added support for GPROC and GPROC1.
838 1999-09-06 James Blandy <jimb@mule.m17n.org>
840 * guile-snarf.c: Deleted. Snarfing should respect CPP
841 conditionals, so it needs to actually run CPP. Bleah.
843 1999-09-05 James Blandy <jimb@mule.m17n.org>
845 Handle errors properly in guile-snarf. (Thanks to Han-Wen Nienhuys.)
846 * guile-snarf.in: Be sure to exit with an error if CPP does.
847 * Makefile.am (.c.x): Delete the .x file and exit with an error
848 status if guile-snarf exits with an error status.
849 * Makefile.in: Regenerated.
851 * snarf.h (SCM_GLOBAL_KEYWORD): Call scm_c_make_keyword, not
852 scm_makekey, which doesn't exist any more. Guess nobody's using
855 * guile-snarf.c: New implementation of guile-snarf, meant to be
856 more robust than the shell script. I think it's complete, but I
857 haven't tested it at all, and I haven't changed the build process
858 to actually use it. We should compare its output against that of
859 the existing shell script, for all source files.
861 * guile-snarf.c (parse_args): Abort if we haven't handled some
864 1999-09-03 James Blandy <jimb@mule.m17n.org>
866 * load.c (scm_search_path): If the filename has any extension at
867 all, ignore the entire list of extensions. Also, don't check whether
868 the file is accessible. If the file exists, accessible or not, we
869 should return it. Inaccessible files should cause an error later.
870 (Thanks to Keisuke Nishida for the suggestions.)
872 1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
874 * gc.c (cleanup, scm_init_storage): Use on_exit if present and
875 atexit not available. (sunos4.1.4 needs it.)
877 1999-09-01 James Blandy <jimb@mule.m17n.org>
879 I take it all back --- bcopy does handle overlapping source and
880 destination areas correctly. At least on every system I could
881 find. But it is better to use AC_REPLACE_FUNCS than to introduce
882 new CPP conditionals.
883 * memmove.c: New file, implementing memmove in terms of bcopy.
884 * scmconfig.h.in: Regenerated.
886 Allocators should use the `void *' type for generic pointers.
887 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
888 argument and return types.
889 * gc.h: Corresponding changes to prototypes.
892 1999-08-31 James Blandy <jimb@mule.m17n.org>
894 * numbers.c (scm_init_numbers): Claim to support the `complex'
895 feature, as expected by (ice-9 format). (Thanks to Ceri Storey.)
897 * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
898 find (ice-9 boot-9) when Guile was compiled in a separate
899 directory from the source. (Thanks to Rodney Brown.)
900 * Makefile.in: Regenerated.
902 * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply
903 table lengths by the size of a single element when growing the
904 table. (Thanks to Bill Schottstaedt.)
906 1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
908 * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
909 SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
910 since that cuts down the time for type dispatch by 50%.
912 1999-08-30 James Blandy <jimb@mule.m17n.org>
914 * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
915 not a correct substitute for memmove, because it doesn't handle
916 overlapping source and destination areas on many platforms.
917 Overlaps are the primary reason to use memmove in the first place.
918 * ports.c (scm_ungetc): Same.
919 * strop.c (scm_substring_move_x): Same.
921 1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
923 * gc.c (scm_init_storage): Skip registration of cleanup on systems
924 which lack atexit. (Is it important that cleanup is made
925 properly? Maybe we should replace all `exit' with `scm_exit' and
928 * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
929 scm_struct_free_standard, scm_struct_free_entity): Declared to
930 return scm_sizet instead of size_t.
932 * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined
933 there on sunos4.1.4.)
935 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
937 * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
938 Account for the case when second argument is unbound.
940 * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
941 (Thanks to Karoly Lorentey.)
943 * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
944 isn't present. (Thanks to Suzuki Toshiya.)
946 * ports.c: Use ANSI C prototypes in definitions. (Thanks to
949 * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
952 * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
953 Bernard Urban and Ian Grant.)
955 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
956 again. (1.3.4 will be binary incompatible with 1.3.2 because of a
957 change in the representation of entities and operators.)
959 1999-08-29 Gary Houston <ghouston@easynet.co.uk>
961 * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
962 don't allocate zero bytes (thanks to Bill Schottstaedt).
964 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
966 * procs.c (scm_setter): Converted to use generic dispatch.
968 * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
971 * load.c (scm_search_path): Don't try extensions which already are
972 present at the end of the filename.
973 (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
975 * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
977 Cleanup and simplification of generic method dispatch.
978 Also, the quadruple representation of entity and operator
979 procedures has been replaced with single.
981 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
983 * print.c (scm_isymnames): Removed #@hash-dispatch.
985 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
986 from eval.c; Support 0 arity methods.
987 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
988 (scm_apply_generic_env): Removed.
989 Replaced slots proc0-3 with procedure.
991 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
992 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
993 SCM_OPERATOR_PROCEDURE.
994 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
995 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
997 * struct.c, struct.h: Replace 4 procedure slots with one.
998 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
1000 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
1003 * eval.c (scm_sym_args): Removed.
1004 (SCM_CEVAL): Simplified entity application.
1005 Moved dispatch code to objects.c.
1007 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
1009 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1011 * sort.c (closureless): Use scm_eval_body.
1013 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
1014 with a symbol as last form was first called normally and then via
1015 `map' or some other mechanism using primitive apply, an ILOC was
1018 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1020 This change extends the representation of primitive procedures
1021 with more data fields, e.g. a place for documentation and true
1022 procedure properties.
1024 * procs.c, procs.h (scm_subr_entry): New type: Stores data
1025 associated with subrs.
1026 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
1027 SCM_SUBR_DOC): New macros.
1028 (scm_subr_table): New variable.
1029 (scm_mark_subr_table): New function.
1031 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
1033 * gc.c (scm_gc_mark): Don't mark subr names here.
1034 (scm_igc): Call scm_mark_subr_table.
1037 This change implements a scheme for letting a generic work as a
1038 shadow for a primitive procedure. If the primitive procedure
1039 can't dispatch on its arguments, control is left over to the
1040 generic. Normal wrong type arg errors will be generated until the
1041 user has hung the first method on the primitive.
1043 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
1045 * procs.c, procs.h (scm_subr_p): New function (used internally).
1047 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
1049 * objects.c, objects.h (scm_primitive_generic): New class.
1051 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
1053 * print.c (scm_iprin1): Print primitive-generics.
1055 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
1056 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
1058 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
1059 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
1060 primitives). NOTE: This means that it is now *required* to use
1061 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
1062 obscured representation that will be removed in the future anyway,
1063 so backward compatibility is no problem here).
1065 * numbers.c: Converted most numeric primitives (all but bit
1066 comparison operations and bit operations) to dispatch on generic
1067 if args don't match.
1070 Better support for applying generic functions.
1072 * eval.c, eval.h (scm_eval_body): New function.
1074 * objects.c (scm_call_generic_0, scm_call_generic_1,
1075 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
1079 Optimization of the generic function dispatch mechanism.
1081 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
1082 called scm_memoize_method instead of doing a second lookup.
1084 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
1089 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
1090 scm_sysintern so that the binding connected with the subr name
1091 isn't cleared when we give set = 0.
1094 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1096 More transparent handling of ports with print states.
1098 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
1099 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
1100 instead of a pair of a port and a print state. We'll need to cons
1101 once extra in scm_printer_apply but the type system will be
1102 cleaner, it will mix better with GOOPS, and, it will be even more
1103 transparent to the user.
1105 * print.c (scm_get_print_state): New procedure: Given an output
1106 port, return the print state associated to it in the current print
1107 chain, if one exists;
1108 (scm_port_with_print_state): New procedure: Associate a
1109 print-state with a port.
1110 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
1111 (scm_printer_apply): Wrap port and pstate as a smob;
1112 (print_state_printer): Removed.
1114 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
1116 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
1119 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
1120 testing (otherwise the port-print-state trick won't be transparent
1121 to the user; one example where this caused problems was in the
1122 (ice-9 format) module).
1124 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1126 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
1127 SCM_UNSPECIFIED instead of the set value.
1129 1999-08-20 James Blandy <jimb@mule.m17n.org>
1131 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
1133 * ports.h (enum scm_port_rw_active): New enum, containing
1134 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
1135 zero). The debugger knows about enums, but doesn't know about
1137 (typedef scm_port): Declare rw_active member to be an enum
1139 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
1141 * ports.c (scm_add_to_port_table): Same.
1142 * strports.c (st_flush, st_end_input): Same.
1144 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
1145 scm_must_realloc, and scm_done_malloc as appropriate.
1147 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1149 * sort.c (quicksort): Added condition to protect the algorithm
1150 from crashing the interpreter if the less predicate is buggy.
1152 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
1154 * fports.c (fport_write): fix line-buffering mode again.
1155 (scm_open_file): recognise 'l' for line-buffering.
1156 (scm_setvbuf): recognise _IOLBF for line-buffering.
1158 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1160 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
1163 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
1164 evaluating closures.
1166 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
1168 * fports.c (fport_write): use memcpy instead of strncpy, in case
1169 the data contains NUL.
1171 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1173 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
1175 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
1176 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
1177 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
1178 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
1179 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
1180 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
1181 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
1182 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
1183 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
1184 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
1185 scm_sym_ as prefix for symbols.
1187 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
1189 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
1190 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
1191 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
1192 scm_sym_atcall_cc): Made global.
1194 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1196 * eval.c (scm_sym_args): Made global.
1198 * objects.c (scm_set_object_procedure_x): Disallow setting of
1199 procedures for pure generic functions.
1201 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
1203 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
1204 Scheme name from lseek to seek, but lseek was added recently so
1205 it shouldn't be a big problem.
1206 * ports.c, gdbint.c, ioext.c: changed callers.
1208 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
1210 * fports.c (fport_input_waiting): if select is used, return 1
1211 instead of whatever FD_ISSET expands to. maybe it will be useful
1212 to interpret the value from the input_waiting ptob procedure as a
1213 lower bound on the number of bytes available.
1215 * Mikael asked for a few names to be changed...
1217 * ports.c (scm_make_port_type): take the write procedure as the
1218 second argument instead of the flush procedure.
1219 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
1220 fflush -> flush, read_flush -> end_input, fclose -> close,
1221 fill_buffer -> fill_input, ftruncate -> truncate,
1222 input_waiting_p -> input_waiting.
1224 * ports.c (end_input_void_port): was read_flush_void_port.
1225 (scm_set_port_end_input): was scm_set_port_flush_input.
1226 (scm_set_port_flush): was scm_set_port_write.
1227 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
1228 (scm_end_input): was scm_read_flush.
1229 (scm_fill_input): was scm_fill_buffer.
1230 (scm_flush): was scm_fflush.
1231 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
1232 (fport_end_input): was local_read_flush.
1233 (fport_flush): was local_fflush.
1234 (fport_close): was local_fclose.
1235 (fport_truncate): was local_ftruncate.
1236 (fport_seek): was local_seek.
1237 (fport_free): was local_free.
1238 (fport_fill_input): was fport_fill_buffer.
1239 * strports.c (st_end_input): was st_read_flush.
1240 (st_truncate): was st_ftruncate.
1241 * vports.c: (sf_flush): was sfflush.
1242 (sf_close): was sfclose.
1243 (sf_fill_input): was sf_fill_buffer.
1245 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
1248 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1250 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
1251 forms now contain the expressions to be dispatched upon instead of
1252 depending on a surrounding lambda or let; Generic function
1253 dispatch has been optimized; `apply' on a generic function now
1254 works a little bit strangely. It uses a trick so that the type
1255 dispatch code in SCM_CEVAL can be reused.
1257 * objects.h, objects.c (scm_apply_generic_env): Added (used by
1259 (scm_operator_p): Added.
1260 (scm_sym_atdispatch): Added.
1261 (scm_set_object_procedure_x): Modified to handle the new style
1263 (scm_object_procedures): New debugging procedure.
1265 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1267 * eval.c, eval.h (scm_sym_args): Added.
1269 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
1271 * feature.c, feature.h (scm_c_run_hook): Added.
1273 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
1274 cdrxnoap and loopnoap instead of begin and loop.
1276 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
1278 * ports.c (scm_putc, scm_puts),
1279 * unif.c (scm_uniform_array_write): use scm_lfwrite.
1280 * ports.c (scm_putc): change type of first argument from int to char.
1282 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1284 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
1285 SCM_IM_HASH_DISPATCH.
1287 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
1288 (scm_si_redfined, scm_si_hashsets): Moved.
1290 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
1291 flag which combines type and status info so that the class
1292 redefinition protocol has zero cost during normal execution.
1294 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
1296 * ports.h (scm_ptob_descriptor): include a write procedure again.
1297 it's more efficient for unbuffered fports (e.g., sockets.)
1299 * ports.c (scm_puts): use ptob->write.
1300 * vports.c (scm_make_sfptob): set write proc in ptob.
1301 * strports.c (scm_make_stptob): set write proc in ptob.
1302 * ports.c (write_void_port): new procedure.
1303 * vports.c (sf_write): new procedure.
1304 * ports.c (scm_lfwrite): use ptob->write.
1305 * strports.c (st_write): new procedure.
1306 * fports.c (fport_write): new procedure.
1307 (scm_make_fptob): set write in ptob to fport_write.
1308 * ports.h: prototype for scm_set_port_write.
1309 * ports.c (scm_make_port_type): initialise ptob write procedure.
1310 (scm_set_port_write): new proc.
1312 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
1314 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
1315 until we've verified that it is actually a port. (Thanks to
1318 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1320 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
1321 code, particularly an unnecessary test (len != size, where len ==
1322 size). (Was this leftovers from debugging code, or have I missed
1323 something profound?)
1325 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
1326 size. (Thanks to James Dean Palmer.)
1328 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
1329 (Thanks to Lorentey Karoly.)
1331 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1333 * eval.c (scm_m_expand_body): Use scm_cons_source.
1335 * struct.c (scm_print_struct): Use vtable name.
1337 * print.c (scm_init_print): Set name of print state type.
1339 * stacks.c (scm_init_stacks): Set name of stack type.
1341 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1343 * eval.c (SCM_CEVAL): Removed old implementation of internal
1346 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
1348 * debug.c, debug.h (scm_reverse_lookup): Added.
1349 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
1350 internal procedure definitions; Don't use scm_i_inner_name.
1352 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
1353 New isym operations.
1355 * eval.h: Added prototypes for multi language support functions.
1357 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
1358 improper lists in the low-level representation, since that will
1359 cause a begin to be prepended at macro expansion.
1361 * eval.c (scm_cons_source): Version of cons which copies source
1362 properties from an existing cell.
1363 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
1365 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
1366 procedure source before calling scm_unmemocopy instead of faking
1369 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1371 Ported `internal defines' fix from SCM. Original ChangeLog entry:
1373 1998-07-09 Radey Shouman <radey@colorage.com>
1375 * eval.c (ceval_1): Modifications to allow rewriting of interal
1376 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
1377 body of which it is the CAR is macro expanded by m_expand_body,
1378 which rewrites internal DEFINE.
1380 (m_expand_body): Added.
1382 (m_macroexp1): Added argument to control error checking:
1383 m_expand_body may speculatively expand forms in the wrong
1384 environments. Made argument number checks conditional on
1387 (m_body): Added, error checks bodies and inserts the ISYM tokens.
1389 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
1392 (m_cond): (m_case): (m_quote): Modified to avoid destructively
1393 changing their argument forms. Since m_expand_body
1394 speculatively macro expands forms the process must be
1397 (m_ident_eqp): Fixed to use proper environment.
1399 (renamed_ident): Added DEFER_INTS_EGC.
1401 Added prototypes for static functions.
1407 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
1408 is false, do not produce an error for unbound variables, return a
1409 pointer to cell_undef instead.
1411 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
1415 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
1416 destructively changing their argument forms. Since m_expand_body
1417 speculatively macro expands forms the process must be reversible.
1419 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
1420 SCM_IM_LET introduced by named lets.
1422 (scm_m_letstar): Use scm_m_body instead of bodycheck.
1424 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
1425 scm_letrec. scm_letrec1 does not check for a null binding and
1426 takes an additional argument to specify the ISYM of the body. Use
1427 scm_m_body instead of bodycheck.
1429 (scm_m_let): Use scm_m_body instead of bodycheck.
1431 (scm_m_expand_body, scm_macroexp): New.
1433 (unmemocopy): Account for ISYMs introduced by scm_m_body.
1435 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
1436 check=1. Throw error for internal defined that have not been
1437 rewritten by scm_m_expand_body.
1439 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
1440 Removed prototype for SCM_APPLY.
1442 * tags.h: Added extern declaration of scm_isymnames.
1444 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1446 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
1448 * lang.c: New file: Beginning of multi-language support.
1450 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
1452 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
1453 (scm_dynamic_wind): Added argument checking for the after guard so
1454 that we don't add garbage on the dynwind chain.
1455 (scm_swap_bindings): Added.
1457 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
1458 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
1459 (scm_isymnames): New isyms for multi-language support.
1461 * eval.c (scm_nil, scm_t): New symbols.
1462 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
1463 forms for multi-language support.
1465 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1467 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
1469 Renamed functions in the random function library interface
1470 from scm_i_XXX --> scm_c_XXX.
1472 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
1474 * ports.c (scm_putc): fix line-buffering.
1476 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1478 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
1479 scm_set_ptob_XXX --> scm_set_port_XXX.
1481 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1483 * ports.c, ports.h (scm_make_port_type): New interface for
1484 creation of port types (replaces scm_newptob). Just as for the
1485 smobs, we need to separate the internal representation of smob
1486 types from the interface, so that we easily can add new fields and
1487 rearrange things without caring about backward compatibility.
1488 This change was forced by the need in GOOPS to create classes
1489 representing port types.
1490 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
1491 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
1492 scm_set_ptob_seek, scm_set_ptob_truncate,
1493 scm_set_ptob_input_waiting_p): New setters.
1494 (scm_newptob): Rewritten to use scm_make_port_type. For backward
1496 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
1497 (scm_prinport): Removed.
1498 (scm_port_print): Added.
1499 (scm_print_port_mode): Added.
1500 (void_port_ptob, print_void_port, close_void_port, noop0):
1501 Removed. Removed #include "genio.h" Added #include "objects.h",
1504 * fports.c (prinfport): Moved code from ports.c.
1505 (local_free): Added.
1506 (scm_fptob): Removed. Instead use new interface.
1507 (scm_make_fptob): Added. (Need to create basic ports in a
1508 specific order in ports.c.)
1510 * strports.c (scm_stptob, prinstpt, noop0): Removed
1511 (scm_make_stptob): Added.
1513 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
1514 (scm_make_sfport): Added.
1516 * filesys.c (scm_dir_print): Don't use the port printing code.
1517 Instead provide specific directory printer.
1519 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
1521 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
1522 scm_ptob_descriptor.
1524 * smob.c (scm_smob_print): Handle non-existing type name nicely.
1525 Removed #include "genio.h"
1527 * objects.c (scm_make_port_classes): New function ptr.
1529 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
1531 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
1533 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
1534 allow the 1st argument to be a fdes or filename as well as a
1535 port (as in the filesys.c version).
1537 * filesys.c (scm_truncate_file): removed.
1539 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1541 * readline.c, readline.h: Removed.
1543 * objects.c, objects.h (scm_port_class): Added.
1544 (scm_class_of): Look up port class in scm_port_class.
1545 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
1546 SCM_INOUT_PCLASS_INDEX): Added.
1549 * Makefile.am: Removed genio.c, genio.x.
1553 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1555 * init.c: Make sure that scm_post_boot_init_modules is called only
1556 once. (Important when using a dumped image.; Thanks to Bernard
1559 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
1561 * guardians.c (scm_guardian_zombify): Separate scanning for
1562 zombies from marking the pairs of the free list.
1564 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
1565 use the macros. (Thanks to Michael Livshin.)
1567 * eval.c (scm_m_lambda): Let bodycheck check the body of the
1568 lambda. Let your sins be purified by the blood of the lambda.
1569 (Thanks to Eric Hanchrow.)
1571 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
1572 (Thanks to Valdis Kletnieks.)
1574 Fixes for EMX from Mikael Ståldal.
1576 * filesys.c: #include <io.h>, if we have it.
1577 * scmconfig.h.in: Regenerated.
1579 * stime.c (ftime): Delete declaration for this function --- let
1580 the system supply it.
1582 Cleanups from John Bley.
1584 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
1586 * gsubr.c: Don't include "gsubr.h" twice.
1588 Cleanups for compilation on Irix 6, from David Kaelbling.
1590 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
1591 regex_t pointer. This is what the callers have, mostly.
1592 (scm_regexp_exec): Don't forget to pass the `rx' argument to
1593 scm_regexp_error_msg.
1595 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
1596 int. That way, if we get a warning on this line, it's more likely
1597 that we're really missing bits we care about.
1599 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
1602 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
1603 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
1604 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
1605 cast at all is more appropriate in every case. At the moment, we
1606 assume everywhere that SCM is an integral type anyway.
1608 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
1610 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
1611 read_pos after scm_fill_buffer.
1613 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
1616 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
1617 fports.c (fport_fill_buffer): implement the interface change.
1619 * ports.c (scm_fill_buffer): interface change: no longer increments
1620 read_pos past the character that's returned. it seems clearer to
1621 leave it to the caller to decide what to do (thanks Jim).
1623 * vports.c (sf_fill_buffer): put the read char into the buffer
1624 as well as returning it.
1626 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure

1631 * strports.c (scm_strprint_obj): simplify. start with initial
1633 (st_seek): don't allow string to be extended if seeking past
1634 the end of a read-only port.
1636 1999-07-12 Gary Houston <ghouston@easynet.co.uk>
1638 * strports.c (st_seek): change the resize checks.
1640 * ports.c (scm_ftruncate): throw error if offset works out negative.
1642 * strports.c (st_flush): increase string size in blocks of
1643 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
1644 it's greater and reset read_buf_size.
1645 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
1646 to be maintained for output ports too (it holds the written
1647 part of the string, while write_buf may have unwritten buffer
1649 (st_truncate): rewritten.
1650 (top of file): added a few notes.
1652 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
1654 Patch from Greg Badros:
1655 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
1656 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
1657 (function pointer) argument to scm_make_gsubr and scm_make_subr
1658 calls. This avoids warnings in C++ programs using guile-snarf.
1660 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
1662 * strports.c (st_grow_port): set pt->read_pos. set
1663 pt->read_buf_size one less than pt->write_buf_size if there's
1664 an unwritten char at the end of the string. similarly for
1666 (st_resize_port): renamed from st_grow_port.
1667 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
1668 seek from read_end instead of write_end for SEEK_END.
1669 (st_ftruncate): calculate current length using readbuf, not write
1671 (scm_strport_to_string): use read_buf_size for length.
1672 (stfill_buffer): don't re-initialise the readbuf.
1674 1999-07-05 Gary Houston <ghouston@easynet.co.uk>
1676 * strports.c (scm_strport_to_string): new procedure.
1677 (scm_call_with_output_string, scm_strprint_obj): use
1678 scm_strport_to_string.

1681 1999-07-08 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1683 * symbols.c (scm_gensym): Bugfix. (Thanks to Johannes Hjorth.)

1687 * smob.c: added scm_make_smob_type_mfpe (), scm_set_smob_mfpe ();
1688 use scm_make_smob_type_mfpe to initialize "free", "flo", "bigpos",
1689 and "bigneg" smob types.
1691 * smob.h: Add do ... while(0) idiom to SCM_NEWSMOB. Added
1692 SCM_RETURN_NEWSMOB macro. Added protos for new functions in
1695 * *.c: Use scm_make_smob_type_mfpe, instead of scm_newsmob, and
1696 use SCM_NEWSMOB or SCM_RETURN_NEWSMOB in constructors instead of
1697 SCM_NEWCELL and setting the CAR/CDR by hand.

1721 buffer before calling the ptob routine.
1723 * strports.c (scm_strprint_obj): bug fix: get pt from the port,

1781 trinary conditional in order for the flag computation to be
1784 1999-06-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1786 * struct.c, struct.h:
1788 In order to support different kinds of deallocation, a destructor
1789 slot has been added to struct vtables. This allows for structs
1790 containing pointers to other memory blocks.
1792 (scm_struct_i_free): New hidden struct slot. Holds destructor for
1793 instances to this vtable.
1794 (scm_struct_free_0): New destructor: Doesn't deallocate data.

1806 scm_struct_i_size which holds the size of light structs.
1807 (scm_struct_i_n_words): This slot has changed meaning. Previously

1809 (scm_alloc_struct): Clear flags.
1810 (SCM_STRUCTF_MASK): 4 new flag positions added => 12 bits.
1812 (struct_num, scm_struct_i_tag): Removed.

1861 1999-06-19 Jim Blandy <jimb@savonarola.red-bean.com>
1863 Patch from Greg Harvey:
1864 * eq.c, eval.c, list.c, ramap.c, vectors.c: Always write parens
1865 around the condition of an `if', `while', etc., even if the
1866 condition is a macro invocation that expands to something
1867 surrounded by parens. It's more readable.
1869 * eval.c (scm_map, scm_for_each): Verify that all arguments are
1870 proper lists, and of the appropriate lengths.
1871 (check_map_args): New function. (Thanks to Greg Harvey for the
1874 1999-06-19 Michael Livshin <mike@olan.com>
1876 * guardians.c (guardian_t): `next' - new field to be used for
1877 chaining the live guardians in a single-linked list during the GC
1879 (GUARDIAN_NEXT): convenience macro to access the `next' field.
1880 (guardians, guardians_size, n_guardians): deleted.

1893 (scm_igc): Check for underflow by seeing if this is negative.
1895 * gc.h (scm_mallocated): Fix declaration.
1896 (Thanks to Greg Harvey.)
1898 * ports.h: #include <sys/types.h>, to get a definition for `off_t'.
1900 1999-06-15 Jim Blandy <jimb@savonarola.red-bean.com>
1902 * stime.c (bdtime2c): Initialize lt->gmtoff and lt->tm_zone from
1903 sbd_time. (Thanks to Eric Hanchrow.)
1905 Fix from Ken Raeburn <raeburn@raeburn.org>:

1907 vector contents, to be used only during garbage collection.
1908 * weaks.h (SCM_WVECT_GC_CHAIN): New macro to access it.
1909 * gc.c (scm_weak_vectors): Now a SCM instead of a SCM*, and now
1911 (scm_weak_size, scm_n_weak): Deleted.
1912 (scm_igc): Use SCM_WVECT_GC_CHAIN to build up a chain of weak
1913 vectors without allocating new storage during GC, using
1914 scm_weak_vectors as the head of the chain.
1915 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
1916 instead of stepping through an array.
1917 (scm_gc_sweep): Update offset used to find start of weak vector to
1919 (scm_init_storage): Set scm_weak_vectors to EOL.
1921 Fix from Ken Raeburn <raeburn@raeburn.org>:
1922 * gc.c (already_in_gc): New variable.
1923 (scm_igc): Set and clear already_in_gc; abort if it's set at
1926 1999-06-14 Jim Blandy <jimb@savonarola.red-bean.com>
1928 Fix from Gary Houston:
1929 * fports.c (local_seek): Signal an error if the seek fails.
1930 * ports.c (scm_lseek): Don't check return value of port's seek
1931 function; it's its job to signal an error if there's a problem.
1933 1999-06-12 Jim Blandy <jimb@savonarola.red-bean.com>
1935 * strports.c (scm_call_with_output_string): Don't include the

1940 * fports.c, fports.h, gc.c, gdbint.c, ioext.c, ports.c, ports.h,
1941 scmsigs.c, strports.c, vports.c: Install the sources which
1942 actually correspond to the changes described below. I got the
1943 ChangeLog entries and the patch from two different places...
1945 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
1947 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
1948 it shows up as terrible performance, as we GC constantly.
1950 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
1951 newline. A bit faster, and definitely hairier.
1952 (scm_read_line): Count newlines here instead.
1954 * strings.c (scm_take_str): New function.
1955 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h
1956 (scm_take_str): New declaration. * ioext.c (scm_read_line): Use
1957 scm_take_str, to avoid copying the string.
1959 Add some simple-minded support for line buffered ports.
1960 * ports.h (SCM_BUFLINE): New flag for ports.
1961 * init.c (scm_init_standard_ports): Request line-buffering on
1962 the standard output port.
1963 * ports.c (scm_mode_bits): Recognize 'l' as a request for line
1965 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
1966 and there's a newline to be written, flush the port.
1968 Gary Houston's open-buffer port patches:
1970 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
1972 * ports.c: (scm_lseek): clear buffers even if just reading current
1975 * fports.c (local_fclose): call local_fflush unconditionally.

1987 ports.h (scm_ptobfuns): add ftruncate.
1988 ports.c (scm_newptob): set ftruncate.
1990 ports.c (scm_ftruncate): new procedure.
1991 fports.c (local_ftrunate), strports.c (str_ftruncate): new procs.

1993 fports.h (scm_port): change size types from int to off_t.
1994 ports.c (scm_init_ports): initialise the seek symbols here
1995 instead of in ioext.c.
1996 strports.c (scm_call_with_output_string): start with an empty
1997 string, so seek and ftruncate can be used.
1999 gdbint.c: adjust string port usage.
2001 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
2003 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
2004 equivalent to fflush for the read buffer.
2005 * ports.c (scm_newptob): set read_flush.
2006 ports.c (void_port_ptob): set read_flush.
2007 fports.c (local_read_flush): new proc. add to ptob.
2008 strport.c (st_read_flush): likewise.
2009 vport.c (sf_read_flush): likewise.
2010 fports.h (struct scm_fport): remove random member. there's nothing
2011 left but fdes. leaving it as a struct to allow for future changes.
2012 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
2013 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
2014 ptob proc if the read buffer is filled.
2016 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
2018 * ports.h (scm_port): add a rw_random member and replace
2019 reading and writing members with rw_active member.
2020 SCM_PORT_READ/SCM_PORT_WRITE: new values.
2022 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
2024 * ports.h (struct scm_port_table): add writing and reading members
2025 to replace write_needs_seek: it isn't good enough for non-fports.
2026 ports.c, ioext.c, fports.c: corresponding changes.
2027 (struct scm_port_table): give it a typedef and rename to scm_port.
2028 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
2029 corresponding changes.
2031 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
2033 * ports.c (scm_newptob): bugfix: set seek member.
2034 * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
2035 and generalised to all port types.
2037 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
2039 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
2040 signals (it was only being done for handlers installed from Scheme).
2041 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
2042 waiting for input caused an EINTR error from read.
2044 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
2046 * ports.h (struct scm_port_table): make all the char members
2047 unsigned, so they convert to int without becoming negative if large.
2049 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
2051 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
2052 with threads enabled. rename this procedure to
2053 fport_wait_for_input and take a port instead of a fdes.
2054 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
2056 * readline.c (scm_readline): Applied a patch from Greg Harvey to
2057 get readline support working again: use fdopen to get FILE objects.
2059 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
2061 * gc.c (scm_init_storage): install an atexit proc to flush the
2063 (cleanup): the new proc. it sets a global variable which can be
2064 checked by the ptob flush procs to avoid trying to throw
2065 exceptions during exit. not very pleasant but it seems more reliable.
2066 * fports.c (local_fflush): check terminating variable and if set
2067 don't throw exception.
2068 * CHECKME: that the atexit proc is installed if unexec used.
2070 * throw.c (scm_handle_by_message): don't flush all ports here.
2071 it still causes bus errors.
2073 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
2074 and move to ioext.c.
2076 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
2078 * ports.c (scm_char_ready_p): check the port buffer and call the
2079 ptob entry if needed.
2081 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
2082 ptob initialisers. use it in char-ready
2084 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
2086 * vports.c (sfflush): modified to write a char (since softports

2111 pointer (and probably vice versa but who knows.)

2114 (scm_puts): rewritten
2115 * fports.c (local_ffwrite, local_fputs): removed.

2298 buffer support removed. take SCM arg, not FILE *.

2346 1999-05-09 Jim Blandy <jimb@savonarola.red-bean.com>
2348 * strop.c (scm_string_capitalize_x): Use the SCM object `s' in
2349 error messages, not the uninitialized string `str'. Love that
2352 * strop.c (scm_substring_move_x): New function, which can handle
2353 arbitrary overlapping substrings.
2354 (substring-move-left!, substring-move-right!): These are
2355 now just synonyms for substring-move!.
2356 * strop.h (scm_substring_move_x): New prototype.
2357 (scm_substring_move_left_x, scm_substring_move_right_x):

2412 * scmconfig.h.in: Regenerated.
2414 * numbers.c (s_bignum): Renamed to s_bignum, and made static.
2415 Libguile should not be exporting random little strings.

2418 More const changes from Ken Raeburn.
2419 * numbers.c (scm_s_bignum, fx): Now const.

2425 * eval.c (scm_i_let): Make this globally visible, to avoid dynamic
2426 linking crashes on NetBSD. (Thanks to Ken Raeburn.)
2428 1999-03-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2430 * numbers.c (isfinite): Define this macro if not defined: Return a
2431 non-zero value if X is finite. (From ISO C 9x standard.)
2432 (scm_inexact_to_exact): Bugfix: Don't pass NaNs to scm_dbl2big.
2433 (Thanks to Jon Trowbridge and Greg Harvey.)
2435 1999-03-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

2460 (scm_system_module_env_p): Assume root environment is no lookup
2463 * debug.c, eval.c, evalext.c, gdbint.c stacks.c:
2464 #include "modules.h".
2466 * modules.c, modules.h, eval.c, eval.h (scm_env_top_level,

2473 * error.c (scm_wta): Pass SCM_LIST1 (arg) instead of SCM_EOL to
2474 scm_misc_error when pos is a string. This allows for dispatching
2475 arbitrary error messages with one argument via SCM_ASSERT:

2478 1999-03-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

2484 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2486 Most of this batch of changes is about how to deal with extended
2487 types when an object system is loaded into Guile. A nice object
2488 system is capable of representing Guile's types as class objects.
2490 For example, we want a regular expression to be of class <regex>.
2491 But regular expressions are smobs which aren't under direct
2492 control of the object system, so there has to be some mechanism
2493 which informs the object system that a new class should be created
2494 which can represent the smob type. I call this a "wrapper class".
2496 * objects.c: #include "smob.h";
2497 (scm_class_keyword): Removed. (Class is automatically created by
2499 (scm_smob_class): Array of smob classes indexed by smobnum.
2500 (scm_make_extended_class): "Plugin" function pointer for creation
2501 of wrapper classes for smob and struct types.
2502 (scm_class_of): Handle compiled closures. (Currently regarded as
2504 Use scm_smob_class to handle smob types;
2505 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
2506 through scm_smob_class;
2509 * smob.c (scm_newsmob): Also create a wrapper class if
2510 scm_smob_class has been initialized.
2512 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
2513 type code and smobnum.
2515 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
2516 (scm_struct_table): Weak key table with auxilliary information for
2517 struct types. Currently used for names and wrapper classes.
2518 (scm_struct_ihashq): Hash function for structs.
2519 (scm_struct_create_handle): Get/create entry in scm_struct_table.
2520 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
2521 for accessing names of vtables. The record implementation in
2522 boot-9.scm currently uses the setter to record the name of record
2523 types. When the object system is initialized, it can use this
2524 information to create wrapper classes with suitable names.
2525 (scm_init_struct): Allocate scm_struct_table.
2526 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
2527 (struct tags are a finite resource and we might want to restrict
2528 the use of tags to vtables only. E.g., Goops only uses tags for
2530 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
2532 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
2535 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
2536 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
2537 Used for access of struct table entries.
2539 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
2540 (scm_hash_fold): New procedure. Used to process all entries in a
2541 hash table (in no particular order).
2543 Argh! For the umpteenth time I got compilation errors because of
2544 the "intuitive" name `kw'. This has to have an end:
2546 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
2547 "kw" --> "keywords" everywhere.
2548 (I doubt that this will cause big compatibility problems since the
2549 application interface is unaffected.)
2551 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
2553 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2555 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
2556 column inums to native form.
2558 Improvement of backtraces: Introduces a new stack narrowing
2559 specifier, #t, for the inner cut. (See further in the comments in
2560 stacks.c:narrow_stack ().)
2562 * procprop.c, procprop.h (scm_sym_system_procedure): New symbol.
2563 (Used to flag certain system procedures which shouldn't turn up in
2566 * eval.c (scm_sym_system_module): New symbol. (Used to flag
2567 modules which aren't "user" modules and the code of which
2568 shouldn't turn up in backtraces.)

2571 Extract the lookup closure from an environment.
2572 (scm_system_module_env_p): New function: Return non-#f if MODULE
2575 * stacks.c: #include "eval.h"; #include "procprop.h";
2576 (narrow_stack): Handle new narrowing specifier #t.
2578 * debug.c (scm_procedure_name): Use name property in the default
2581 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
2583 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
2585 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
2586 procedure throughout.
2588 * print.c (scm_iprin1): Removed extraneous space when printing
2589 procedure-with-setters.
2591 Entity and operator setter slots were introduced as a complement
2592 to the <procedure-with-setter> type in order to support entities
2593 and operators with setters in a reasonable and efficient way.

2641 * readline.c (in_readline, reentry_barrier_mutex): Make these
2644 * readline.c: #include <sys/time.h> and "iselect.h", so we can

2700 SYMB now point to const.
2702 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2704 * print.c (scm_iprin1): Use scm_procedure_name instead of
2705 scm_procedure_property for compiled closures.
2707 * tags.h (scm_tc7_pws): New procedure type. Four representations
2708 for procedure-with-setters were considered before selecting this
2711 1. A closure where the CODE and ENV slots are used to represent
2712 the getter and a new SETTER slot is used for the setter. The
2713 original getter is stored as a `getter' procedure property. For
2714 closure getters, the CODE and ENV slots contains a copy of the
2715 getter's CODE and ENV slots. For subr getters, the CODE contains
2718 2. A compiled closure with a call to the getter in the cclo
2719 procedure. The getter and setter are stored in slots 1 and 2.
2721 3. An entity (i.e. a struct with an associated procedure) with a
2722 call to the getter in the entity procedure and the setter stored
2723 in slot 0. The original getter is stored in slot 1.
2725 4. A new primitive procedure type supported in the evaluator. The
2726 getter and setter are stored in a GETTER and SETTER slot. A call
2727 to this procedure type results in a retrieval of the getter and a
2728 jump back to the correct eval dispatcher.
2730 Representation 4 was selected because of efficiency and
2733 Rep 1 has the advantage that there is zero penalty for closure
2734 getters, but primitive getters will get considerable overhead
2735 because the procedure-with-getter will be a closure which calls
2738 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
2739 <procedure-with-setter>, but together with rep 2 it suffers from a
2740 three level dispatch for non-GOOPS getters:
2742 cclo/struct --> dispatch proc --> getter
2744 This is because the dispatch procedure must take an extra initial
2745 argument (cclo for rep 2, struct for rep 3).
2747 Rep 4 has the single disadvantage that it uses up one tc7 type
2748 code, but the plan for uniform vectors will very likely free tc7
2749 codes, so this is probably no big problem. Also note that the
2750 GETTER and SETTER slots can live directly on the heap, using the
2751 new four-word cells.
2753 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,
2754 SCM_SETTER): New macros.

2835 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
2837 * Makefile.in: This changed, for some reason I don't really
2838 understand, when I ran automake in the top level directory. This
2839 may be contamination by Cygnus internal releases. If you re-run
2840 automake and this change gets reverted, don't worry about it.

2870 scm_guardian_gc_init, scm_guardian_zombify, scm_guard,
2871 scm_get_one_zombie, scm_init_guardian): This is an implementation
2872 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
2873 David Eby (1993) "Guardians in a Generation-Based Garbage
2874 Collector" ACM SIGPLAN Conference on Programming Language Design
2875 and Implementation, June 1993 ftp://ftp.cs.indiana.edu

2891 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2893 Move the procedure slots of entities to invisible slots (so that
2894 we can have operator class objects which themselves are entities).
2895 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
2896 SCM_STRUCTF_ENTITY): New constants.
2898 * struct.c (scm_make_struct): Allocate "invisible" room for
2899 procedures if SCM_STRUCTF_ENTITY is set in vtable.

2911 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
2913 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
2914 of syntactic forms, similar to SCM_PROC.
2915 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
2916 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
2917 for the name symbols when needed.
2919 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
2921 * Makefile.in: Regenerated.
2923 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
2925 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
2926 take the address of _into; it might be a register. Just have
2927 scm_debug_newcell return the new cell.
2928 * gc.c (scm_debug_newcell): Just return the new cell, instead of
2929 taking the address of a place to store it as an argument.
2930 * gc.h (scm_debug_newcell): Change declaration.
2931 (Thanks to Greg Harvey.)
2933 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

2954 * objects.h: Removed slots direct_supers and direct_slots from the
2955 definitions of the rudimentary classes described by objects.h.
2957 * objects.c, objects.h (scm_entity_p): New procedure. Together
2958 with the predicates scm_procedure_p and scm_struct_p, this
2959 predicate makes it possible to differ between structs, entities
2962 * modules.c, modules.h (scm_resolve_module): New function.
2964 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2966 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,

2977 * procprop.h (scm_i_procedure_arity): Added declaration.
2979 * procprop.c (scm_i_procedure_arity): Made global; New code to
2980 handle operators and entities.
2981 (scm_procedure_property): No need to call scm_procedure_p since
2982 scm_i_procedure_arity now does all necessary type checking.
2983 Added #include "objects.h".
2985 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
2986 s_add_hook_x --> s_remove_hook_x.
2987 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.

2991 (scm_make_hook): Optional argument defines number of arguments to
2993 (scm_make_named_hook): Take number of args as second arg.
2994 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
2995 boot-9.scm for a while); First arg is the hook. The rest are
2996 arguments passed on to the hook procedures.
2998 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
3000 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
3001 scm_logbit_p): Do the computation in ulongs. This is not as nice
3002 as doing it in bignums, but at least it's good enough for
3003 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
3005 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
3006 subexpressions. (Thanks to Charbel Jacquin.)
3008 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
3010 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
3011 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
3012 (scm_make_named_hook): New function.
3014 * feature.c: Added #include "eval.h".
3016 * modules.c (scm_make_module): Beautify the module.
3018 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3020 * modules.c, modules.h: New files: C interface to modules. (This
3021 is necessary in order to interface the object system to Guile
3022 properly. The guts of these modules will be replaced by the new
3023 module system in the future.)
3025 * init.c: Added #include "modules.h"
3026 (scm_boot_guile_1): Call scm_init_modules.
3027 (invoke_main_func): Call scm_post_boot_init_modules.
3029 * Makefile.am: Added modules.c, modules.x, modules.h.
3031 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
3033 * procs.c: #include "objects.h"
3034 (scm_procedure_p): Return #t also on structs which are operators.
3036 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
3037 <operator-metaclass> and <entity-class> to <standard-class>,
3038 <operator-class> and <entity> in order to conform with STKlos
3041 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
3042 which isn't an operator.
3043 (SCM_APPLY): Ditto, but jump to badproc.
3045 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
3047 * eval.c (SCM_CEVAL): Allow structs implanted in code.
3048 Previously, structs implanted in code were interpreted as forms
3049 the operator of which was a gloc. We solve this by checking for
3050 the zero in the emulated vcell in the struct vtable. Since
3051 implanted structs always will look like forms with a gloc
3052 operator, execution will only be slowed down by maximally one
3053 extra test-and-branch per application.
3055 * evalext.c (scm_definedp): Removed check for isyms; Added a
3056 second optional argument: It is now possible to supply an
3057 evaluation environment in which to look for the symbol.
3059 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3061 * readline.c (scm_init_readline): Set
3062 rl_basic_word_break_characters. (Thanks to Ian Grant.)
3064 * coop.c (coop_condition_variable_wait): Removed
3065 (coop_condition_variable_wait_mutex): Folded logic of
3066 coop_mutex_unlock into coop_condition_variable_wait_mutex to
3067 prevent condvar signal lossage. Previously, another thread could
3068 start to run after unlocking the mutex but before putting the
3069 current thread on the wait queue. If that thread then would
3070 signal the first, the signal would be lost. (Thanks to Christian
3073 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3075 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
3078 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3080 * objects.c (scm_i_make_class_object): Renamed from
3081 make_class_object; exported; error checking moved to
3082 scm_make_class_object and scm_make_subclass_object.
3083 (scm_make_class_object, scm_make_subclass_object): Use
3084 scm_i_make_class_object.
3085 (scm_make_subclass_object): Let the subclass have same metaclass
3088 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3090 * debug.c (scm_debug_options): Bugfix: Set the value of
3091 scm_stack_checking_enabled_p after setting debug options;
3092 #include "stackchk.h". (Thanks to Richard Polton.)
3094 1998-11-13 Radey Shouman <rshouman@metro2000.com>
3096 * unif.c (scm_array_contents): removed unnecessary test for 0
3099 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3101 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
3102 Replaced by macro `collect' in boot-9.scm.
3104 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3106 * eval.c (scm_copy_tree): Copy source properties if existent.
3108 * debug.c (scm_start_stack): Copy source when evaluating. (If we
3109 don't, we may end up passing memoized source to a transformer.)
3111 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3113 * stack.c (get_applybody): Help function which lookups the first
3114 body form of the apply closure.
3115 (read_frames): Prevent the source of the first form of the apply
3116 closure from being recorded. This would only be confusing.
3118 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
3119 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
3121 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
3123 * stacks.c (read_frame): Bugfix: Removed lingering `else'
3125 (read_frames): Use SCM_MACROEXPP.
3127 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3129 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
3130 don't contain interesting information since all arguments are
3131 present in the frame which applies the compiled closure anyway.);
3132 Skip the transformer application frames.
3134 * print.c (scm_iprin1): Print gsubrs as primitives.
3136 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3138 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
3140 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
3141 that we can identify these in a backtrace. (This change doesn't
3142 introduce any significant speed penalty.)
3144 * eval.c: Added note about `serial-map' using scm_map.
3146 * read.c, read.h (scm_read_options, scm_read_opts): Removed
3147 readline options. They should reside in their own options array.
3149 * readline.c, readline.h (scm_readline_options,
3150 scm_readline_opts): Moved readline options here.
3152 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3154 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
3155 SCM_ROCHARS instead of SCM_CHARS.
3157 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
3158 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
3160 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3162 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
3163 This is quite important since the latter clears the
3164 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
3165 every single character read...
3167 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3169 * print.c (scm_iprin1): Removed suspect looking (and indeed
3170 malevolent) semicolon after test for user supplied closure print
3171 procedure. (Thanks to Telford Tendys.)
3173 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
3174 (scm_memq, scm_memv, scm_member): Do argument checking *before*
3175 starting to search the list. Removed call to sloppy_mem_check.
3177 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
3178 procedures: Same as scm_delq_x et al, but delete maximally one
3181 * options.c (scm_options, scm_init_options): GC-protect option
3182 values of type SCM. (Thanks to Telford Tendys.)
3184 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3186 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
3187 make sure that there always is a "real" scm_lookupcar.
3189 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3191 * read.c, read.h (scm_read_opts): New read options
3192 "history-length" and "history-file".
3193 (scm_read_options): Stifle history to history length.
3195 * readline.c (scm_read_history, scm_write_history): New procedures.
3197 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3199 * eval.h (scm_macro_eval_x): Removed declaration.
3201 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
3202 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
3203 Renamed and made global.
3205 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
3206 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
3208 * evalext.c, evalext.h: New files. Contain non-R5RS things
3209 having to do with evaluation.
3211 * evalext.c (scm_serial_map): New procedure: Version of `map'
3212 which guarantees that the procedure is applied to the lists in
3214 (scm_m_sequence_to_list): New syntax: Version of `begin' which
3215 returns a list of the results of the body forms instead of the
3216 result of the last body form.
3217 (scm_definedp, scm_m_undefine): Moved from eval.c
3219 * evalext.h (scm_m_sequence_to_list): Added declaration.
3221 * macros.c, macros.h: New files.
3222 (scm_procedure_to_syntax, scm_procedure_to_macro,
3223 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
3224 scm_macro_name, scm_macro_transformer): Moved from eval.c
3225 (scm_make_synt): Moved from eval.c
3227 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
3229 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
3232 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
3234 * debug.c, print.c: Added #include "macros.h".
3236 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3238 This change adds the ability to use `unread-char' multiple times
3239 without interspersed reads and adds the new procedure
3240 `unread-string'. The change is optimized for the common case of
3241 unreading a single character. This is also the reason behind the
3242 choice to store characters in the port itself: in most cases no
3243 extra malloc is required.
3245 The amount of code in some macros in ports.h has been increased to
3246 the extent that they would fit better as C functions, but, since
3247 this code belongs to the port representation, such functions
3248 should be placed in ports.c which would cause calls back and forth
3249 between ports.c and genio.c. That is not good for performance.
3250 Also, keeping them as macros allows the compiler to do some
3251 optimizations which are needed to make the current interface
3252 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
3254 One benchmark (Guile startup time) indicates an increase of
3255 loading speed of 1%. Another (reading (using `read') boot-9.scm
3256 10 times) shows no change in performance.
3258 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
3259 made to find a beautiful solution.)
3261 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
3262 (SCM_TRY_CLRDY): New macro: Only clear the first unread
3263 character. (SCM_CLRDY clears all.)
3264 (SCM_N_READY_CHARS): New macro: Returns number of unread
3265 characters in a port. Returns wrong answer if SCM_CRDYP is false.
3266 (struct scm_port_table): New fields: `entry' contains port table
3267 index, `cp' points to last unread char, `cbuf' is the buffer for
3268 unread chars, `cbufend' points after end of the character buffer.
3270 * ports.h, ports.c (scm_unread_string): New procedure.
3271 (scm_grow_port_cbuf): New function.
3273 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
3275 (scm_generic_fgets), fports.c (local_fgets): Use a loop
3276 to read unread characters. Use SCM_TRY_CLRDY instead of
3279 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
3281 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
3283 * genio.c, genio.h (scm_ungets): New function.
3285 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
3288 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3290 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
3291 declarations. (Thanks to Russ McManus.)
3293 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3295 * numbers.c (num2long): As a software archeologist, I'm proud of
3296 this finding! :) Preliminary dating suggests an almost 4 year old
3297 remnant from the SCM ancestor. The sample has been removed from
3298 the finding site and is now safely stored in the repository.
3300 * numbers.h: Removed prototype for num2long.
3302 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
3304 * gh_data.c (gh_scm2doubles): Make it possible to pass result
3305 array as second arg.
3306 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
3307 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
3308 * gh.h: Updated and added prototypes.
3310 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
3312 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
3314 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
3316 * guile-snarf.in: Never generate an empty file. (Thanks to
3319 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
3320 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
3321 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
3322 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
3323 gh_new_procedure5_0): Specify argument types, to appease C++
3324 compilers. (Thanks to Brad Bowman.)
3326 Bug reports from Russ McManus:
3327 * guile-snarf.in: If the CPP environment variable is set, use that
3328 as the C preprocessor, instead of the preprocessor autoconf
3330 * snarf.h (SCM_PROC): Cast the function pointer passed to
3331 scm_make_gsubr, to satisfy C++.
3333 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
3334 Use the handler passed, instead of ignoring it and using
3335 gh_standard_handler. (Thanks to Etienne Bernard.)
3337 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
3339 * ports.h: Put text after #endif in comment. (Thanks to Nicolas

3363 use-emacs-interface in the root module, so the repl code can see
3364 it. See today's change to top-repl in ice-9/boot-9.scm.
3366 * filesys.c (set_element, get_element): Make sure that `element'
3367 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
3368 Boekemeier and Jorgen "forcer" Schaefer.)
3370 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
3372 * chars.c (scm_charnames): In ASCII character name table, make
3373 newlines print as #\newline by default, not #\nl.
3375 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
3376 alphabetical order. Oh thrills. But it helps me know how far
3377 along in the compilation I am.
3378 * Makefile.in: Regenerated.
3380 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3382 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
3383 #bytes(...) to #y(...), and syntax for short vectors from
3384 #short(...) to #h(...). This may seem nutty, but, like the other
3385 uniform vectors, byte vectors and short vectors want to have the
3386 same print and read syntax (and, more basic, want to have read
3387 syntax!). Changing the read syntax to use multiple characters
3388 after the hash sign breaks with the conventions used in R5RS and
3389 the conventions used for the other uniform vectors. It also
3390 introduces complexity in the current reader, both on the C and
3391 Scheme levels. (The Right solution is probably to change the
3392 syntax and prototypes for uniform vectors entirely.)
3394 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
3396 Don't use local_fgets on sockets; ftell doesn't work on sockets.
3397 (Thanks to Jorgen "forcer" Schaefer.)
3398 * ports.h (SCM_NOFTELL): New flag.
3399 * fports.c (local_fgets): If it's set, use the generic fgets.
3400 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
3402 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3404 * script.c (scm_compile_shell_switches): Add handling of -q switch
3405 (inhibit loading of user init file).
3406 (scm_shell_usage): Add usage text for -q switch.
3407 (scm_compile_shell_switches): Always load user init file first if
3408 it is loaded at all.
3410 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
3412 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
3413 and is now broken under NetBSD. I can't fathom what it's trying
3414 to do, so I've replaced it with something that I do understand,
3415 which seems to work, and which isn't broken on NetBSD. "Progress?
3416 You Decide." (Thanks to Perry Metzger.)
3418 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
3419 signed/unsigned comparison.
3421 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
3423 Warning fixes from Greg Harvey:
3424 * unif.c (scm_array_set_x): initializer for pos
3425 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
3426 * struct.c (scm_struct_ref, scm_struct_set_x): Added
3427 initializers for field_type, since EGCS so desparately wants to
3429 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
3430 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
3431 when GUILE_DEBUG is defined.
3432 * dynwind.h (scm_wind_chain): Same.
3433 * ports.h (scm_pt_size, scm_pt_member): Same.
3434 * print.h (scm_current_pstate): Same.
3435 * procs.h (scm_make_cclo): Same.
3437 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
3439 Handle short and long long uniform arrays properly. (Thanks to
3441 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
3442 raeql_1): Add cases for scm_tc7_svect (short vectors) and
3443 scm_tc7_llvect (long long vectors).
3445 Change the way libguile and boot-9.scm are timestamped, to try to
3446 get rid of these spurious mismatch warnings. Now both
3447 libguile/versiondat.h and ice-9/version.scm are generated directly
3448 by the configuration process, rather than having version.scm
3449 generated directly, and libguile/versiondat.h generated by the
3450 Makefile, which is generated by configure. It seems that
3451 sometimes the Makefile would change, but versiondat.h depends on
3452 Makefile.in, not Makefile, so it wouldn't get rebuilt.
3453 * Makefile.am (versiondat.h): Target removed; this is generated
3454 directly by the configure script now.
3455 (BUILT_SOURCES): Remove versiondat.h.
3456 * versiondat.h.in: New file, transformed by the configure script
3458 * Makefile.in: Regenerated.
3460 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
3461 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
3462 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
3463 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
3464 if we want to use them in a header file some day, we can. (Thanks
3465 to Michael Livshin.)
3467 * stime.c (scm_get_internal_real_time): Do the arithmetic using
3468 SCM numbers, so we won't have rollover problems; the range of a
3469 signed long in milliseconds is about 25 days. (Thanks to Karl
3472 Don't redefine sleep and usleep; fix this problem now.
3473 * coop.c (sleep, usleep): Remove declarations; we don't use or
3474 redefine these any more.
3475 (scm_thread_usleep, scm_thread_sleep): New functions which do the
3476 job of usleep and sleep in a thread-friendly way. We can use
3477 these in the rest of Guile. Define versions for systems both with
3478 and without iselect.
3479 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
3480 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
3481 we're just using it, not redefining it, we can use a K&R style
3483 (sleep): Declare this, too, if the system hasn't.
3484 (scm_sleep, scm_usleep): Use scm_thread_sleep and
3485 scm_uthread_sleep if they're available; otherwise, just call the
3487 * scmconfig.h.in: Regenerated.
3489 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
3491 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
3493 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
3495 * threads.c: Doc fix.
3497 The argument type of usleep varies from system to system,
3498 as does the return type. We really shouldn't be redefining usleep
3499 at all, but I don't have time to clean that up before the 1.3.
3500 release. It's on the schedule for afterwards. (Thanks to Julian
3502 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
3504 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
3505 * scmconfig.h: Regenerated.
3507 * simpos.c (scm_software_type): Procedure deleted. This isn't the
3508 right way to handle system variation. Autoconf's approach is the
3510 * simpos.h (scm_software_type): Declaration deleted.
3512 * script.c (scm_find_executable): Don't test if unix is #defined
3513 here; first, NetBSD doesn't #define it, and second, it's the wrong
3514 way to go about these things. (Thanks to Perry Metzger.)
3515 (dld_find_executable): Delete this MSDOS support code. This isn't
3516 the way we want to support this; it needs to be rethunk at a
3519 * genio.c (scm_do_read_line): Don't just politely check that the
3520 line was either non-empty or EOF. Abort if it's empty and not
3523 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
3525 * scmconfig.h.in: Regenerated.
3527 * libguile.h: Don't omit the dynamic linking functions. (Thanks
3530 * genio.c (scm_do_read_line): Count lines correctly when the file
3531 doesn't end in a newline.
3533 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
3535 * genio.c (scm_do_read_line): Maintain the line count correctly.
3536 (Thanks to Harvey J. Stein and Greg Harvey.)
3538 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
3541 * numbers.c (big2str): Protect t from garbage collection until
3542 we're done. (Thanks to Gary Houston.)
3544 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
3546 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
3548 * Makefile.in: Regenerated.
3550 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
3551 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
3554 Do magic to mix reads and writes on stdio FILE-based ports.
3555 (Thanks to Christian Lynbech.)
3556 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
3558 (pre_read, pre_write): New functions.
3559 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
3560 local_fputs): Call them.
3561 (local_fflush): Mark the port as ready for reading and writing.
3562 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
3563 flags on new port objects. This might not be accurate --- who
3564 knows what state the FILE * is in when we get it --- but it won't
3565 do extraneous calls to fflush or fseek, so it's no worse than the
3566 behavior before this change.
3567 * ports.h: Add comment.
3569 Centralize the creation of port objects based on stdio FILE * in
3570 fports.c; don't just throw them together anywhere.
3571 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
3572 what the rest of Guile wants. Don't set the revealed count;
3573 that's only appropriate for stdin, stdout, stderr.
3574 (scm_standard_stream_to_port): This function does set the revealed
3576 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
3577 not scm_stdio_to_port.
3578 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
3579 * fports.c (scm_open_file): Same.
3580 * posix.c (scm_pipe): Same.
3581 * socket.c (scm_sock_fd_to_port): Same.
3582 * ioext.c (scm_fdopen): Same.
3583 (scm_freopen): Moved from here to...
3584 * fports.c (scm_freopen): ... here. This is really something that
3585 munges the internals of an fport, so it should go here.
3586 * fports.h (scm_stdio_to_port): Adjust prototype.
3587 (scm_standard_stream_to_port, scm_freopen): New protoypes.
3588 * ioext.h (scm_freopen): Prototype removed.
3590 * filesys.c (set_element, get_element): This can work on both pipe
3591 and file ports, so use SCM_FPORTP to typecheck, instead of testing
3594 * scmconfig.h.in: Regenerated.
3596 Change the definition of the functions in scm_ptobfuns so that
3597 they get passed the port object, not the port's stream.
3598 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
3599 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
3600 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
3601 Pass the port itself to the scm_ptobs function.
3602 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
3603 scm_generic_fgets): Same.
3604 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
3605 getc_void_port, fgets_void_port, close_void_port): Just change the
3606 argument names; these functions don't really do anything.
3607 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
3608 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
3609 port as an argument, and use SCM_STREAM to get the stdio FILE *.
3610 Also, use prototyped definitions, and get rid of the extra
3612 (scm_fptob, scm_pipob): We don't need casts here any more.
3613 * strports.c (prinstpt): Use prototype declarations.
3614 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
3615 and use SCM_STREAM to get the string info. Also, use prototyped
3616 definitions, and get rid of the extra declarations.
3617 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
3620 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
3621 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
3623 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
3624 scm_fgets, for consistency.
3625 (scm_fptop, scm_pipob): References updated.
3627 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
3629 Include the source location in error messages for scripts.
3630 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
3631 stack is still there when we catch the error.
3632 * throw.c (handler_message): If we are handling an error with a
3633 message, then put together the proper arguments and call
3634 scm_display_error, instead of scm_display_error_message. That
3635 displays source location, if it can find it.
3637 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
3639 * gc.c (scm_unprotect_object): Change this so that calls to
3640 scm_protect_object and scm_unprotect_object nest properly.
3641 (scm_protect_object): Doc fixes.
3643 * strings.c (scm_string_set_x): Require the argument to be a
3644 writable string, not a substring or a symbol.
3645 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
3646 (Thanks to John Redford and Charbel Jacquin.)
3648 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
3650 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
3652 * eval.c (safe_setjmp): Remove this misunderstanding.
3653 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
3656 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
3658 * libguile.h: Mark these as C declarations, for compilation by C++
3661 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
3662 __cplusplus clause. I seriously doubt this ever worked the way
3663 the author seems to have intended.
3665 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
3667 Utterly needless cleanups to hopelessly messy code.
3668 * ports.c: Doc fixes.
3669 (scm_fflush): Moved to ...
3670 * genio.c (scm_fflush): ... here, amongst all the other port
3671 method invocation functions.
3672 * genio.h, ports.h: The prototype moves too.
3674 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
3676 * backtrace.c (display_error_body): The current frame does not
3677 always have a parent frame; consider a function called directly
3678 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
3681 * alloca.c (alloca): Undo yesterday's changes, and simply call
3682 malloc directly for storage, and abort if we don't get what we
3683 want. The situation is much simpler --- just call malloc. Emacs
3684 has bizarre/evil requirements (signal handlers might malloc unless
3685 you set this global flag, so you have to set the flag around all
3686 calls to malloc) which we are certainly not going to conform to,
3687 so we can do the simple and obvious thing.
3689 * coop.c (coop_condition_variable_wait): Make this function
3690 static. It's only useful internally --- you should never just
3691 wait on a condition variable.
3692 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
3694 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3696 * unif.c (scm_array_set_x): Accept any kind of number as an
3697 element for a uniform vector of doubles. This is more consistent
3698 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
3700 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
3701 works; I can't conveniently test it myself. (Thanks to Dvid
3702 Tillman for the bug report.)
3704 * init.c: Doc fixes.
3706 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
3707 from here, not from scm_compile_shell_switches (which is a pretty
3708 dumb place to do it).
3709 (scm_load_startup_files): New function.
3710 (scm_ice_9_already_loaded): Variable moved to here from script.c.
3711 * script.c (scm_compile_shell_switches): Don't load the startup
3713 (scm_ice_9_already_loaded): Variable moved.
3714 * init.c (scm_load_startup_files): Prototype for new function.
3715 * gh_init.c (gh_enter): Doc fix.
3717 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3719 Some anti-warning changes from Greg Harvey.
3720 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
3721 warnings when it doesn't understand our NORETURN declarations in
3723 * posix.c (scm_mknod): Similar.
3725 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3727 * posix.c (scm_getpwuid): If we can't find an entry, return our
3728 own message, instead of using scm_syserror --- the getpwMUMBLE
3729 functions don't set `errno' to anything interesting.
3731 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3733 Get rid of warnings from the cooperative threading system.
3734 * threads.h (scm_single_thread_p, scm_yield,
3735 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
3736 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
3737 scm_wait_condition_variable, scm_signal_condition_variable): Add
3738 prototypes for these Scheme-visible functions.
3739 * coop-defs.h (coop_next_runnable_thread,
3740 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
3741 Prototypes for these here, even though they're from iselect.c.
3742 (coop_condition_variable_wait, coop_join): Add prototypes.
3743 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
3744 scm_threads_free_condvar): Make these smob functions static.
3745 * coop-threads.h (coop_init): Give this a real prototype.
3746 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
3747 (coop_next_runnable_thread): No need to provide prototype; it's in
3750 * scmconfig.h.in: .detarenegeR
3752 * iselect.c, threads.c: Doc fixes.
3754 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3756 * Makefile.in: Regenerated with a patched automake, to get
3757 dependency generation right when using EGCS.
3759 * inet_aton.c (inet_aton): Add prototype, to remove compiler
3760 warning. (Thanks to Robert Pluim.)
3762 * inet_aton.c (inet_aton): Reassure the compiler that the
3763 arguments to the <ctype.h> macros are all unsigned characters, not
3766 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3768 Getting rid of more warnings...
3769 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
3770 today's change to ../configure.in.
3771 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
3772 * scmconfig.h.in: Regenertaded.de.,.__
3773 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
3774 (scm_localtime, scm_mktime): Use a const char * to manipulate the
3777 * readline.c: Doc fix.
3778 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
3779 * readline.h (scm_filename_completion_function): Add prototype.
3780 (scm_init_readline): Make this into a prototype.
3782 * readline.c (scm_filename_completion_function): Use SCM_PROC to
3783 declare this, instead of calling scm_make_subr manually.
3785 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
3787 * readline.h (scm_init_readline): Add prototype for this.
3788 (scm_init_readline): Make this a real prototype.
3790 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
3792 Warning fixes from Maciej Stachowiak:
3793 * backtrace.h (scm_display_application, scm_backtrace): Add
3795 * debug.c (scm_m_start_stack): Make this function static.
3796 * fluids.h (scm_fluid_p): Add prototype.
3797 * procprop.c (scm_i_procedure_arity): Make this function static.
3798 * regex-posix.c (scm_regexp_error_msg): Make this function static.
3799 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
3800 * root.h (scm_dynamic_root): Add external prototype.
3801 * scmsigs.h (scm_usleep): Add external prototype.
3802 * script.h (scm_init_script): Use prototype, not K&R decl.
3803 * stacks.h (scm_stack_id): Add external prototype.
3804 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
3806 1998-09-30 Mark Galassi <rosalia@cygnus.com>
3808 * gh.h: took out the definitions of vset and vref, since they are
3809 replaced by the proper vector routines that correspond to the R4RS
3812 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
3814 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
3815 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
3816 third argument, a C expression that should result in a SCM value,
3817 which is used to initialize the variable. Reimplemented
3818 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
3821 * version.h (scm_libguile_config_stamp): Add prototype.
3822 (From Maciej Stachowiak.)
3824 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
3826 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
3827 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
3829 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
3831 * print.c (scm_iprin1): Rather than having one i, and using it in
3832 several places, declare a fresh i local to each block where it is
3833 used, and give it a signedness appropriate to its use in each case.
3834 (scm_iprlist): Same.
3836 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
3837 comparison warnings.
3839 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
3840 signed/unsigned clashes.
3842 * posix.h (scm_tmpnam): Added prototype.
3844 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
3845 scm_make_subclass_object): Add external prototypes.
3847 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
3848 comparison is okay here.
3850 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
3852 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
3853 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
3855 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
3858 * load.c (swap_port): Make this function static.
3860 * load.c (scm_search_path): Make max_path_len and max_ext_len
3861 unsigned, since they're compared against string sizes.
3863 * load.c (init_build_info): Make i unsigned.
3865 * ioext.h (scm_read_line): Add prototype.
3867 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
3868 scm_hash_fn_remove_x): Make hash bucket index local variable k
3869 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
3870 accurately as possible.
3872 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
3873 comparisons, and range checking to make sure those casts are
3876 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
3877 signed/unsigned comparisons.
3879 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
3880 avoid signed/unsigned comparisons.
3881 * smob.h (scm_numsmob): Change extern declaration to match.
3883 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
3884 avoid signed/unsigned comparisons.
3885 * ports.h (scm_numptob): Change extern declaration to match.
3886 (scm_current_load_port, scm_set_port_line_x,
3887 scm_set_port_column_x): New prototypes.
3889 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
3890 test code, and it causes warnings.
3892 * gh.h (gh_int2scmb, gh_uniform_vector_length,
3893 gh_uniform_vector_ref): Added prototypes.
3895 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
3896 debugging support unconditionally. That's backtrace.c, stack.c,
3897 debug.c, and srcprop.c.
3898 (EXTRA_libguile_la_SOURCES): Omit those from here.
3899 * Makefile.in: Regenerated.
3901 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3903 * options.c (scm_options): Bugfix: Allow empty list of options!
3905 * debug.c, debug.h (scm_single_step): Removed.
3906 (scm_with_traps): New procedure. This procedure could easily be
3907 written in Scheme but needs to be highly optimized.
3909 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
3911 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
3912 Check SCM_TRAPS_P before trapping.
3914 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
3916 Changes to avoid signed/unsigned comparison warnings.
3917 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
3918 (scm_gc_sweep): Make n and j local to the blocks they're used in,
3919 so they can have appropriate types for each application. Make i
3920 signed. Use initializers in some spots. I'll probably pay for
3922 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
3923 (scm_must_realloc): Make nm unsigned.
3924 (init_heap_seg): Make new_seg_index and n_new_objects signed.
3925 (scm_init_storage): Use prototype-style definition, and make the
3927 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
3928 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
3930 * filesys.c (scm_readlink): Make local vars rv and size ints, to
3931 avoid signed/unsigned comparison warnings, and because the return
3932 value of readlink may be -1. Don't bother casting the third
3933 argument to readlink.
3935 * filesys.c (scm_dirname, scm_basename): Move these to their own
3936 page, at the end of the file.
3937 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
3939 * eval.h (scm_eval_options_interface): Add external prototype for this.
3940 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
3942 * eval.c (scm_lookupcar1): Make this static.
3944 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
3945 Make these prototype declarations, not K&R-style.
3947 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
3948 unsigned comparison warning.
3950 * appinit.c: File removed. It had a single function in it, empty,
3951 whose reason for existence is explained in no documentation or
3952 comment. I think it's there as a default for some Tcl-style
3953 initialization, but Tcl abandoned that approach a while ago.
3954 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
3955 (BUILT_SOURCES): Remove appinit.x.
3956 * Makefile.in: Regenerated.
3958 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3960 * Makefile.in: Regenerated using the last public version of
3961 automake, not the hacked Cygnus version.
3963 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
3965 Remove Totoro kludge.
3966 * Makefile.in, scmconfig.h.in: Regenerated.
3967 * init.c, readline.c: Don't check if TOTORO is #defined.
3969 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
3971 * Makefile.am: Adjust for new thread configuration system.
3972 (INCLUDES): Include the value of THREAD_CPPFLAGS.
3973 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3975 (THREAD_LIBS): Definition deleted; automake will generate such
3976 things automatically.
3977 * Makefile.in: Regenerated.
3979 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3981 Simplify smob and port marking; set the mark bit in the generic
3982 marking code, and make marker routines only responsible for
3983 turning up outgoing pointers.
3984 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3985 before calling the marking function. Don't call the marking
3986 function if it's zero.
3987 * markers.c (scm_mark0): Just return #f. This function isn't
3988 necessary at all now, but it's harmless to call it. We'll leave
3989 it in so other folks' code doesn't croak at link time.
3990 (scm_markcdr): Don't call SCM_SETGC8MARK.
3991 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3992 * dynl.c (mark_dynl_obj): Same.
3993 * root.c (mark_root): Same.
3994 * srcprop.c (marksrcprops): Same.
3995 * unif.c (markra): Same.
3996 * variable.c (scm_markvar): Same.
3997 * ports.c (scm_markstream): Same.
3998 (void_port_ptob): Specify zero for our marking function.
3999 * debug.c (debugobjsmob): Same.
4000 * dynwind.c (guardsmob): Same.
4001 * filesys.c (dir_smob): Same.
4002 * fluids.c (fluid_smob): Same.
4003 * fports.c (scm_fptob, scm_pipob): Same.
4004 * mallocs.c (mallocsmob): Same.
4005 * regex-posix.c (regex_t_smob): Same.
4006 * smob.c (freecell, flob, bigob): Same.
4007 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
4008 * throw.c (jbsmob, lazy_catch_funs): Same.
4010 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
4012 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
4013 scm_copy_tree on code in order not to let memoized code to leak
4014 out. Thus, scm_copy_tree needs to copy vectors as well since
4015 quasiquote can introduce evaluated code also inside vector
4018 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
4020 * eval.c (scm_copy_tree): Removed ability to copy vectors.
4022 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
4023 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
4026 * unif.c: Say that ivect and uvect are of type signed and unsigned
4027 long instead of int in commentary so that it correctly describes
4030 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
4032 * stime.c: Removed declaration of strptime. (It should be
4033 declared by the system headers. If it turns out that some systems
4034 don't, we'll handle that then.) (Thanks to Greg Troxel.)
4036 * stime.h: Renamed TIMEH --> STIMEH
4038 * backtrace.c (scm_display_error, scm_display_backtrace): In order
4039 to increase portability, don't use structure assignment.
4040 (Thanks to Nicolas Neuss.)
4042 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
4044 (finalize_fd_sets): Added empty statement after last case label.
4045 (Thanks to Nicolas Neuss.)
4047 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
4050 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
4052 * init.c, readline.c: OK, I won't have these readline.x bug
4053 reports anymore. We've had them since April. The current reason
4054 is a completely unintelligible failure of totoro.red-bean.com to
4055 do the test for rl_getc_function in libreadline correctly. This
4056 kludge overrides the test if we're on totoro so that the snapshot
4057 generation process can work.
4059 * readline.c: Define a strdup replacement if not existent on system.
4061 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
4063 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
4064 This change makes scm_make_vector R5RS compatible. We cannot keep
4065 the third argument since people want to be able to deduce the form
4066 of the C function call only by looking at R5RS. (At the same time
4067 we have removed some unnecessary complexity!)
4069 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
4070 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
4071 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
4072 argument in call to scm_make_vector.
4074 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4076 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
4077 This macro is useful in applications.
4079 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
4081 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
4082 (scm_parse_path, scm_search_path): New Scheme level procedures.
4084 * load.h (scm_internal_parse_path, scm_parse_path,
4085 scm_search_path): Declared.
4087 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4089 * filesys.c (dirname, basename): New procedures.
4091 * init.c (scm_boot_guile_1): Removed condition around
4094 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
4095 new data type (guards) for representation of C level guards and
4096 data on the wind chain.
4097 (scm_internal_dynamic_wind): New function.
4099 * dynwind.h: Declare scm_internal_dynamic_wind.
4101 * root.h (scm_root_state): Added scm_cur_loadp.
4103 * root.c (mark_root): Added comment about cur_loadp.
4105 * load.c: #include "dynwind.h";
4106 (scm_primitive_load): Use scm_inner_dynamic_wind to update
4109 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
4111 * ports.c (current-load-port): New procedure.
4113 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4115 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
4116 not a tty, return #f.
4118 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
4119 to Julian Satchell and Roland Kaufmann.)
4121 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
4122 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
4124 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
4126 * debug.h, debug.c (scm_start_stack): New function. Implements
4127 the guts of old scm_m_start_stack.
4129 * debug.c (scm_m_start_stack): Use scm_start_stack.
4131 * init.c (scm_start_stack, scm_restart_stack): Renamed to
4132 start_stack and restart_stack. (These have static scope.)
4134 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4136 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
4137 readline functions to come in release 2.3. (Thanks to Chet
4139 (handle_errors): Use the above functions.
4141 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4143 * readline.c: Improvements for readline support: Handle errors
4144 better; Implement before-read-hook.
4146 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4148 * init.c (scm_boot_guile_1), readline.c: Test for
4149 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
4150 assure that we have version >= 2.1.)
4152 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
4154 * readline.c (scm_readline): Defer interrupts while we're calling
4157 * readline.c (scm_add_history): Bugfix: Do strdup before giving
4158 away the string to add_history.
4159 (completion_function): Do completion for readline. (Thanks to
4161 (scm_filename_completion_function): New procedure: Filename
4163 (current_input_getc): New function. Use this one instead of
4164 standard getc from readline.
4166 * throw.c, throw.h (scm_handle_by_throw): New function: This
4167 handler throws errors to next handler on the dynwind chain.
4169 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
4171 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
4174 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4176 * procprop.c (scm_i_procedure_arity): New function. Returns arity
4178 (scm_procedure_properties): Modified to return arity together with
4180 (scm_procedure_property): Added the read-only property `arity'.
4181 (scm_set_procedure_property_x): It is an error to set the `arity'
4184 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
4185 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
4187 * procprop.h (scm_sym_arity): New symbol.
4189 * objects.c (scm_set_object_procedure_x): New procedure: Use this
4190 to set the dispatch procedure of an operator or entity object.
4192 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
4193 Made procedure slots read-only.
4195 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
4196 scm_tcs_cons_gloc case in zero args switch; Fixed args
4197 construction for operators in scm_tcs_cons_gloc case in two args
4200 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4202 * fluids.c: Removed use of assert.h (in order to avoid
4205 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
4207 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
4209 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
4210 change makes the evaluator safer at the cost of evaluation speed.
4211 It handles the case when the user has added a non-immediate
4212 improper end of the application form, e.g., `(+ 0 . x)'.
4213 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
4214 minimize the extra cost as much as possible. The new code is
4215 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
4216 problem with structs planted directly in the code (e.g. by a
4217 macro). This no longer causes segmentation fault. (Thanks to
4220 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
4221 arg `proc' in order to be able to throw errors; New argument
4224 * Removed extra #include "debug.h"
4226 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
4228 * scmsigs.c: Declare usleep as returning void on some systems.
4229 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
4232 * coop.c (usleep): Return void on some systems.
4234 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4236 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
4238 * coop.c: Changed return type of usleep to int.
4240 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
4241 isn't found in the OS.
4243 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
4244 isn't enabled. (Thought that I had made this change ages ago...)
4246 * iselect.c: Declare bzero if not defined by OS.
4248 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4250 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
4251 condition. (Thanks to John Tobey.)
4253 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
4254 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
4257 * __scm.h: Start the long-term project of moving to POSIX threads.
4258 Phase 1: Classification of all critical sections.
4259 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
4260 for A sections. (See comments in __scm.h for details.)
4262 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
4263 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
4265 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4267 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
4268 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
4269 (libpath.h, versiondat.h): Replaced dependency on Makefile with
4270 dependencies on $(srcdir)/Makefile.in
4271 $(top_builddir)/config.status in order to avoid circularity.
4273 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
4274 from argc if argc was 0 initially.
4276 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
4277 in generation of libpath.h.
4279 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
4281 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
4282 libguile from 2 to 3.
4284 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
4286 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
4288 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
4290 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
4291 scm_set_port_column_x, scm_port_filename,
4292 scm_set_port_filename_x): Removed optional arguments. Added
4293 proper argument checking.
4295 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
4296 stack size in machine words.
4298 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
4299 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
4300 to Ole Myren Röhne.)
4302 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
4304 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
4305 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
4307 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
4310 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
4311 procedure apply: Copy argument lists before pushing them unto the
4312 environment so that the environment won't get mutated due to
4313 manipulation of procedure arguments. This should perhaps be
4314 regarded as a temporary solution until someone finds a more
4315 efficient one. (Thanks to Maciej Stachowiak.)
4317 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
4319 * script.c (scm_compile_shell_switches): Use "guile" as default
4320 zero arg if argc is NULL.
4322 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
4324 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
4325 is zero. (Thanks to Dirk Herrmann.)
4327 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
4329 * ports.c (scm_add_to_port_table): First line is now line 0
4330 (was 1). (Interface changed according to suggestion by Per
4333 * backtrace.c (display_header): Add 1 to line and column numbers
4334 when presenting them to the user.
4336 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
4337 from debug.c --> eval.c
4339 * eval.h, eval.c (scm_eval_options_interface): New options
4341 (SCM_EVAL_STACK): New option: Size of newly created stacks,
4342 i.e. stacks for new threads.
4344 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
4346 * eval.c (unsafe_setjmp): Removed with #if 0.
4348 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
4351 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
4352 to avoid compiler warnings.
4354 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
4356 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
4358 * throw.c (handler_message): Print message on current error port
4359 instead of default error port. (Thanks to Maciej Stachowiak.)
4361 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
4363 * ports.c (scm_add_to_port_table): allocate in units of
4364 struct scm_port_table *, not struct scm_port_table.
4365 * posix.c (scm_close_pipe): remove the port from the port table
4367 Thanks to Rob Engle for both fixes.
4369 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4371 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
4372 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
4374 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4376 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
4378 * backtrace.c (display_error_body, display_backtrace_body),
4379 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
4380 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
4381 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
4382 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
4385 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
4386 don't receive the jmpbuf arg anylonger.
4387 (scm_catch): Don't accept a #f tag.
4388 (scm_throw): Check that key is a symbol.
4389 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
4391 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
4393 * async.c (async_pending): Removed declaration.
4395 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4397 * dynwind.c (scm_wind_chain): New debug function.
4399 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
4400 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
4401 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
4402 extra layer of functions around the body and handler of a thread.
4403 This extra layer makes sure that the handler is called in the
4404 dynamic context of the surround (= empty dynwind list), but under
4405 the *dynamic root* of the body. We can not use the dynamic root
4406 of the surround since that root belongs to another thread => stack
4407 is not handled correctly. It may seem ugly to use this extra
4408 layer, but the extra cost in terms of execution time is really
4409 negligible compared to the total amount of time required to create
4410 a thread, and it would reduce maintainability to duplicate the
4411 crucial and complicated steps performed by cwdr.
4413 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
4414 (SCM_ALLOW_INTS): Added thread switching code before interrupts
4415 get re-enabled. The important effect of this is that interrupts
4416 are blocked during thread switching so that thread data structures
4417 don't risk getting messed up by an unfortunate signal.
4418 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
4419 seems to do more aggressive optimization which actually move
4420 instructions around in these macros in a fatal way. Therefore:
4421 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
4422 just superstitious...)
4423 (SCM_TICK): Maybe do a context switch and take care of asyncs.
4424 This macro should be used instead of SCM_ASYNC_TICK since the
4425 latter doesn't do context switches any more.
4427 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
4428 instead of SCM_ASYNC_TICK.
4430 * coop.c, iselect.c: Since thread switches are now performed with
4431 interrupts masked, we can't use the old mechanism of delivering
4432 signals immediately when they arrive. Signals must instead be
4433 delivered when the asyncs run *after* the end of the critical
4434 section in scm_internal_select. But this also means after context
4435 switch so that the signal will be delivered to a different thread.
4436 To avoid this, I have changed the protocol of
4437 coop_wait_for_runnable_thread and friends so that they are allowed
4438 to return the original thread. So, if a signal arrives during
4439 scm_internal_select, we won't any longer be forced do a context
4440 switch, but can remain in the same thread and deliver the signal
4443 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
4444 scm_asyncs_pending and made it global.
4446 * iselect.c: Small fixes.
4448 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
4449 coop_condition_variable_init, coop_condition_variable_wait,
4450 coop_condition_variable_signal): Changed return type from `void'
4451 to `int'. This is to adhere closer to the pthreads interface.
4452 This, in turn, is part of an attempt to provide C versions of the
4453 mutex and condition variable primitives which can be part of a
4454 frontend to COOP or pthreads.
4456 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
4457 coop_condition_variable_destroy): New functions.
4459 * coop-threads.c (scm_wait_condition_variable): Use
4460 coop_condition_variable_wait_mutex.
4462 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
4463 Definitions moved to coop-defs.h.
4465 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
4466 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
4467 scm_cond_destroy): New C interface to mutecis and cond vars.
4469 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4471 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
4473 * iselect.c: Now several threads can wait on the same file
4474 descriptor. The behaviour is compatible with OS select: All
4475 threads waiting for the fd return with the same status.
4477 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4479 * coop-threads.c, threads.h (scm_spawn_thread): New function.
4480 Can spawn a thread from application C code.
4482 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4484 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
4485 gh_doubles2scm): New functions.
4487 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
4489 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
4490 commented-out version of gh_eval_str()
4492 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
4494 * socket.c (scm_bind): free soka after use.
4496 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
4498 * stime.c (tzvar): new variable.
4499 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
4500 avoid memory leaks when allocating.
4502 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
4504 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
4507 * gc.c, tags.h: Doc fixes.
4509 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4511 * eval.c (macro-eval!): Removed. This function was a design bug.
4512 It allowed memoized code to leak out to the scheme level. Most
4513 things that you could do with `macro-eval!' can be done with
4516 1997-12-20 Tim Pierce <twp@skepsis.com>
4518 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
4519 scm_fgets now depends on ftell(3) to know how many bytes were
4522 1997-12-15 Tim Pierce <twp@skepsis.com>
4524 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
4525 dealing with strings.
4527 1997-12-13 Tim Pierce <twp@skepsis.com>
4529 Make %read-line more suitable for implementing read-line efficiently.
4530 * ioext.c (scm_read_line): Strip the terminating newline from a
4531 string, and return a cons of the string and its terminator.
4533 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
4534 of the string that is read is stored in this memory location.
4535 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
4536 * genio.c, genio.h (scm_do_read_line): Update caller.
4537 * ports.h (scm_ptobfuns): Update typedef.
4538 * fports.c (scm_fptob, scm_pipob): Update struct.
4540 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4542 * filesys.c (set_element): Return file descriptor.
4543 (fill_select_type): Return the highest file descriptor.
4544 (scm_select): Tell select about the highest file descriptor. On
4545 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
4546 Therefore the extra overhead for calculating the maximum fd seems
4547 to be more than compensated. Is this correct? In any case,
4548 scm_internal_select will be much faster with this info.
4549 (scm_select, fill_select_type, set_element): Don't accept any kind
4550 of object in the file descriptor list or vector.
4552 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4554 * iselect.c (finalize_fd_sets): Bugfix.
4556 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4558 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS

4562 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
4564 * simpos.c (scm_system): always define: use sysmissing if not
4565 available. Check for HAVE_SYSTEM instead of _Windows (does
4566 Windows lack system or does it have an unusable one?).
4567 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
4568 Let the argument be optional: if not supplied, call system(NULL).
4570 * ports.c (scm_close_port): relax the type check from OPPORTP to
4571 PORTP; closing a closed port is allowed.
4573 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
4575 * fports.c (scm_fgets): Return if the last char in a chunk is
4576 newline. When fgets returns a string whose length is `size-1', it
4577 is ambiguous whether a whole line was retrieved, so we must check
4578 explicitly whether a line terminator is present.
4580 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4582 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
4583 before taking the CDR. (Thanks to Harald Meland.)
4585 * filesys.c (scm_stat): Slightly optimized.
4587 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
4589 * ports.c (scm_close_port): Make sure the port is open before
4592 * guile-snarf.in: Pass args through to gcc in a way that preserves
4593 whitespace boundaries. (Thanks to Greg Badros.)
4595 1997-12-02 Tim Pierce <twp@skepsis.com>
4597 * stacks.c (scm_frame_procedure): Reverse the logic in the return
4598 statement. (Thanks to Doug Evans for pointing this out.)
4600 1997-12-01 Tim Pierce <twp@skepsis.com>
4602 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
4604 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
4606 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
4607 errno macro expansion of this field name. (errno is a C
4608 preprocessor macro on some systems.)
4610 1997-11-29 Tim Pierce <twp@skepsis.com>
4612 * iselect.c: Doc fix.
4614 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>

4623 * root.c (mark_root): Don't mark the_last_stack_var.
4625 * root.h (scm_root_state): Removed the_last_stack_var.
4627 * throw.c: Added #include "fluids.h"
4628 (ss_handler): `the-last-stack' is now a fluid.
4630 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
4631 --> the_last_stack_fluid.
4633 * backtrace.c: Added #include "fluids.h"
4634 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
4635 (scm_backtrace): `the-last-stack' is now a fluid.
4637 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
4638 after scm_init_fluids.
4640 1997-11-28 Tim Pierce <twp@skepsis.com>
4642 * iselect.c: #ifdef USE_THREADS around thread-related includes.
4644 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
4645 DLSYM_ADDS_USCORE to decide whether to add an underscore.
4647 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4649 * iselect.c (coop_next_runnable_thread,
4650 coop_wait_for_runnable_thread): Disable interrupts so that no
4651 async is executed before a potential error_revive.
4652 (scm_internal_select): Disable interrupts during the parts of the
4653 code which manipulate the sleep queue and the file descriptors.
4655 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4657 * Makefile.am: Added iselect.c and iselect.h.
4659 * coop.c (coop_qinit): Initialize fields used by
4660 scm_internal_select.
4661 (coop_qget, coop_qget, coop_tmp_queue): Made global.
4662 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
4663 replacement in iselect.c.
4664 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
4665 coop_join): If GUILE_ISELECT enabled, use
4666 coop_wait_for_runnable_thread instead of
4667 coop_next_runnable_thread.
4668 (usleep, sleep): New replacements for system functions if
4669 GUILE_ISELECT is enabled.
4671 * coop-threads.h: Declare coop_wait_for_runnable_thread.
4673 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
4675 * filesys.c: Added #include "iselect.h". Moved FD-macros to
4676 iselect.h. Implement Scheme level `select' using
4677 scm_internal_select. (See NEWS.)
4679 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
4681 * init.c: Call scm_init_iselect.
4683 * iselect.h, iselect.c: New files. Implements

4686 1997-11-27 Tim Pierce <twp@skepsis.com>
4688 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
4689 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
4690 and scm_must_free, since ultimately the string returned will be copied
4691 by scm_makfrom0str anyway. Also, read any characters that may have
4692 been pushed onto the port with scm_ungetc.
4693 * ports.c (scm_generic_fgets): Same as for scm_fgets.
4694 * ioext.c (scm_read_line): Free string after Guilifying it.
4695 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.

4699 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
4701 * gh.h: Safely wrap prototypes for c++ usage.
4703 1997-11-25 Mark Galassi <rosalia@cygnus.com>
4705 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
4706 gh_repl (argc, argv).
4708 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
4710 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
4711 and to invoke scm_shell().
4712 (gh_launch_pad): took out the loading of boot-9.scm from here,
4713 since it is probably best to let the user control that. In fact,
4714 gh_repl() now invokes scm_shell() which does that.
4716 1997-11-23 Mark Galassi <rosalia@cygnus.com>
4718 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

4740 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
4741 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
4743 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
4745 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
4746 configure.in was changed).
4748 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
4750 * Makefile.am (modinclude_HEADERS): Include readline.h here.
4751 * Makefile.in: Regenerated.
4753 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
4755 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
4756 OPORT is an `open' port, not an output port.
4758 * filesys.c (scm_close, set_element, get_element, scm_chown,
4759 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
4760 SCM_COERCE_OUTPORT to cope with the printstate/port magic.

4763 scm_port_column, scm_set_port_column_x, scm_port_filename,
4764 scm_set_port_filename_x, scm_port_mode,
4765 scm_close_all_ports_except, scm_set_current_output_port,
4766 scm_set_current_error_port): Likewise
4767 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
4768 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):

4771 * backtrace.c (display_backtrace_body): Likewise
4772 * fports (scm_setvbuf): Likewise

4780 Minor problems with substring-related tag changes.
4781 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
4782 exactly what we want to leave in to detect substrings.
4783 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
4784 * tags.h: Fix diagrams and comments describing the S tag bit;
4785 remove vestigial remarks about the D tag bit.

4787 * strings.c: Formatting tweaks.
4789 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
4790 variable first; then SCHEME_LOAD_PATH, with a warning message.
4791 (scm_parse_path): New function.
4792 * script.c: Doc fixes.
4794 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
4796 Readline support, from Daniel Risacher.
4797 * readline.c, readline.h: New files.

4801 * Makefile.in: Regenerated.
4802 * scmconfig.h.in: Regenerated, after change to ../configure.
4804 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4806 * gh.h: gh_vector_set -> gh_vector_set_x
4808 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4810 * gh_data.c (gh_vector_set_x): changed name to make it consistent
4811 with the ! -> _x mapping when going from Scheme to C.
4813 1997-10-19 Mark Galassi <rosalia@cygnus.com>
4815 * gh.h (gh_reverse):
4823 (gh_assoc): added these gh_ functions implemented as macros.

4826 (gh_string_equal_p): added these two missing predicates.
4828 * gh_list.c (gh_append):
4833 (gh_set_cdr_x): added these routines as I go through and try to
4834 complete the picture R4RS functions that should be mirrored in the
4837 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4839 * tags.h (scm_tc7_substring): Changed the comment and code to
4840 conform with the changes below. Folks! We have suddenly two new
4841 free tc7 codes!!! Jummy, jummy!
4843 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
4845 * Makefile.in: Rebuilt.

4903 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
4905 * gh_test_c.c (c_vector_test): some improvements on the vector
4908 * gh.h (gh_vector): this used to exist but do the wrong thing.
4909 Now it (almost) does the right thing, though it takes a list
4910 instead of the individual arguments. I need to see how it could
4912 (gh_list_to_vector): added this function as a macro. Corresponds
4913 to Scheme's (list->vector ...).
4914 (gh_vector_to_list): added this function as a macro. Corresponds
4915 to Scheme's (vector->list ...).
4917 * gh_data.c (gh_vector_ref): renamed from gh_vref to

4920 resembles the Scheme routines more.
4921 (gh_make_vector): this used to be (stupidly) called gh_vector().
4922 This is the right name, since it does the same thing as the Scheme
4923 (make-vector ...) procedure.
4925 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
4927 * ports.h: #include "libguile/print.h"

4942 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
4944 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
4945 macros should by convention not test for NIMPness.)
4946 (SCM_COERCE_OPORT): Adjust indentation.
4948 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
4949 SCM_NIMP test before SCM_PRINT_STATE_P.

4959 printing: Also output hex code of vtable so that type identity
4960 will be indicated as well.
4961 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
4962 Removed struct_printer_var; Removed struct-vtable-offset;
4963 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
4964 vtable-offset-user): New constants.

4969 the type represented by this vtable.
4971 * print.c (scm_iprin1): Don't print arguments of macro
4972 transformers. (They are always: exp env.); Bugfix: Unmemoize
4973 transformer source with correct environment.
4975 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
4977 Streamlining of call-with-dynamic-root:

4982 (cwdr_handler): New function.
4983 (scm_internal_cwdr): New function to perform the function of cwdr
4984 but take args that are more useful to C code. Also, the handler
4985 is now invoked *outside* of the new dynamic root, like the docs
4986 say. We no longer have to catch absolutely all errors, the caller
4987 is responsible for using a handler that does not throw, if he
4989 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4990 * root.h (scm_internal_cwdr): New prototype.
4992 Even more but risky streamlining:
4994 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4995 allocation of the jumpbuf of a root continuation. The changes
4996 below are controlled by it. They are now deactivated.
4997 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4998 the JMPBUF of the scm_rootcont to NULL before returning.
5000 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
5001 when they are non-NULL.
5002 (scm_gc_mark): Likewise, mark only when non-NULL.
5004 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
5005 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
5007 * gc.c (scm_done_malloc): New function.

5019 (scm_free_print_state): Set `revealed' field to false.
5020 (scm_iprin1): Call user supplied closure printer with
5021 scm_printer_apply. Print in the traditional way when there isn't
5022 one or when it returns #f.
5023 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
5024 Accept a port/print-state pair in addition to just a port.
5025 (scm_prin1): Don't return the print_state to the pool when it has
5027 (scm_printer_apply): Set `revealed' field of print_state to true.
5028 (scm_init_print): Set scm_print_state_vtable.
5029 (print_state_fluid, print_state_fluid_num): Removed.
5031 * throw.h (scm_handle_by_proc_catching_all): New prototype
5032 throw.c (scm_handle_by_proc_catching_all): New function
5034 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
5036 * Makefile.in: Regenerated with automake 1.2c.
5038 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
5040 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
5041 was looping endlessly.
5043 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
5045 * strports.c (scm_eval_string): Don't close the port.
5047 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
5048 former returns a nice normal integer. (Thanks to Daniel
5051 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
5053 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
5054 makefile variable as a build parameter called LIBS. The
5055 build-guile program will use this, for the time being.
5056 * Makefile.in: Regenerated.
5058 Thanks to Shiro Kawai:
5059 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
5060 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
5063 * Makefile.in: Regenerated with automake 1.2a.
5065 * script.c (scm_compile_shell_switches): If we hit the -c or --
5066 arguments, don't set the car of (command-line) to scm_usage_name,
5067 the prettified name of the guile executable; give it the full
5068 path, the way shells usually handle $0.
5070 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5072 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
5073 Scheme-level name `array-map' and renamed `serial-array-map' to
5074 `serial-array-map!'.
5076 * backtrace.c: Introduced exception handlers which now enclose
5077 `display-error' and `display-backtrace' so that error reporting
5078 won't get into infinite loops if an error occurs during displaying
5079 of the error. This can very easily happen with user supplied
5080 print call-back routines.
5082 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5084 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
5085 the names `serial-array-map' and `array-map' should be removed.)
5087 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
5089 * init.c (scm_boot_guile_1): Added scm_init_objects ().
5090 Added #include "objects.h"
5092 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
5093 Add #include "feature.h".
5095 * Makefile.am (libguile_la_SOURCES): Added objects.c.
5096 (modinclude_HEADERS): Added objects.h.
5098 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
5099 This test is needed at many places in the code and should be
5100 abstracted. (Motivated by the need of this test in libguiletk.)
5102 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
5103 (scm_eval_string), load.c (scm_primitive_load,
5104 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
5105 Use SCM_EOF_OBJECT_P.
5107 * eval.c (scm_init_eval): Add feature `delay'.
5109 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5111 * scmhob.h: Removed.
5113 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5115 * list.h (SCM_LISTn): New macros. Make list creation in C code
5116 prettier. The idea comes from STk.
5118 * sequences.h, sequences.c, append.h, append.c: Removed. These
5119 files implemented non-R4RS operations which would encourage
5120 non-portable programming style and less easy-to-read code.
5122 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
5125 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
5126 sequences.h, #include append.h.
5128 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
5131 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
5133 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
5135 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
5137 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5139 * eval.c: Added #include "objects.h"
5141 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
5144 * smob.c (scm_smob_prehistory): Create two objectsmobs with
5145 adjacent smob numbers.
5147 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5149 * procprop.h: Added declaration of scm_i_inner_name.
5151 * gsubr.c: New global symbol scm_i_inner_name.
5153 * debug.c (scm_procedure_name): Try procedure property
5154 `inner-name' if `name' fails.
5156 * print.c (scm_iprin1): Use scm_macro_name.
5158 * eval.c (scm_m_define): Give names to macros as well; Only the
5159 first top-level definition gives a procedure/macro a name.
5160 Otherwise confusing names can turn up in backtraces.
5161 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
5162 `name'; Give names to macros as well.
5164 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
5165 (scm_macro_transformer): Use SCM_CLOSUREP instead of
5168 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5170 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
5172 (prinmacro): Removed. The code has been moved/merged into print.c
5173 in order to decrease code redundancy. We want macros to print in
5174 a way equivalent to procedures, and it would be silly to duplicate
5175 the required code. (We don't want to maintain two places.)
5176 (macrosmob): Print field is now a NULL pointer.
5178 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
5179 scm_macro_transformer): New prototypes.
5180 (scm_tc16_macro): Declared.
5182 * print.c (scm_iprin1): Added code for printing of macros. Macros
5183 are now printed in a way equivalent to procedures.
5185 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
5187 * procs.h (scm_closure_p): Added declaration.
5189 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5191 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
5192 Shouldn't pass "heap" as the subr name.
5194 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
5196 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
5197 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
5198 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
5199 gh_equal_p): Use SCM_NFALSEP, instead of testing against
5200 SCM_BOOL_T. Any non-false value is true.
5202 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5204 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
5205 scm_gensym): Added prototypes.
5207 * symbols.c (scm_gensym): New function. This will speed up
5208 certain types of applications (such as macro systems) which
5209 generate lots of symbols.
5211 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5213 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
5215 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
5217 * unif.c (scm_shap2ra): tighten the checking of the array dimension
5218 specifier, since (2) or (2 . 3) would cause SEGV.
5219 (scm_transpose_array): more argument checking fixes.
5221 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
5223 * Makefile.in: Regenerated.
5225 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
5227 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
5229 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5231 * error.c, error.h (scm_error_callback): Removed (see NEWS).
5233 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
5235 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
5236 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
5239 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
5240 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
5241 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
5242 scm_array_p, scm_array_rank, scm_array_dimensions,
5243 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
5244 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
5245 scm_array_prototype): Added case scm_tc7_wvect.
5247 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
5249 * errno.h: prototype for scm_strerror.
5250 * error.c (scm_strerror): new procedure.
5252 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5254 * list.c (scm_list_append_x): Allow non-pair as last argument.
5255 This is consistent with the R4RS append and is probably the
5256 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
5258 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
5260 * stime.h: prototype for scm_times.
5261 * stime.c (scm_times): new procedure.
5262 * ioext.c (scm_fseek): if the first argument is a file descriptor
5264 (scm_ftell): if the first argument is a file descriptor call lseek
5266 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
5267 * filesys.c (scm_chmod): if the first argument is a file descriptor,
5269 (scm_chown): if the first argument is a port or file descriptor,
5271 (scm_truncate_file): new procedure.
5272 Add DEFER/ALLOW INTS to a few other procedures.
5273 (scm_fsync): new procedure.
5274 (scm_open_fdes): new procedure.
5275 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
5277 (scm_fcntl): the first argument can now be a file descriptor. The
5278 third argument is now optional.
5280 * posix.c (scm_execl, scm_execlp): make the filename argument
5281 compulsory, since omitting it causes SEGV.
5282 (scm_sync): return unspecified instead of #f.
5283 (scm_execle): new procedure.
5284 (environ_list_to_c): new procedure.
5285 (scm_environ): use environ_list_to_c. disable interrupts.
5286 (scm_convert_exec_args): take pos and subr arguments and
5287 improve error checking.
5289 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5291 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
5292 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
5293 argument to SCM_ASSERT. Furthermore, the name of the function
5294 should be passed as first argument when signalling
5295 SCM_WNA. (Thanks to Thomas Morgan)
5297 * gsubr.c (scm_gsubr_apply): From Radey Shouman
5298 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
5299 dispatches on the number of actual args has a default case
5300 reporting an internal error. This is a vestige from a version
5301 that mallocated a SCM vector to hold the arguments. In the
5302 current version this check is too late: if it ever happens we will
5303 have already overstepped the bounds of the array.
5305 Also, the patch [...] adds a check for too many actual arguments."
5307 mdj: Removed check for "internal programming error".
5309 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5311 * gh_io.c (gh_write): New function.
5313 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
5314 throw.c (scm_internal_stack_catch): New sibling to the other catch
5315 functions. Code moved from gh_eval.c.
5316 throw.h: Added header.
5317 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
5318 scm_internal_stack_catch.
5320 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5322 * ioext.h: fix up prototypes.
5323 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
5324 Scheme name is now dup->fdes.
5325 (scm_dup_to_fdes): make the second argument optional and
5326 fold in the functionality of scm_primitive_dup.
5327 (scm_primitive_dup): deleted.
5329 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
5331 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
5332 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
5333 ultrix are defined. Use setvbuf instead of setbuf.
5334 (scm_setvbuf): new procedure.
5335 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
5336 (scm_setfileno): moved from ioext.c.
5337 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
5338 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
5340 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5342 * fluids.c (scm_fluid_p): New function.
5343 * fluids.h (scm_fluid_p): New prototype.

5347 * print.c (scm_iprin1): Enter printed structures into the print
5348 state as nested data while they are printed.
5349 (print_state_fluid, print_state_fluid_num): New variables.
5350 (scm_init_print): Initialize them.
5351 (scm_iprin): If print_state_fluid carries a print_state, use that
5352 instead of creating a new one.
5353 (scm_printer_apply, apply_stub, struct apply_data): New
5354 definitions to help with calling printer functions written in
5356 * print.h (scm_printer_apply): New prototype.
5358 * struct.c (scm_print_struct): Use scm_printer_apply to call the
5359 user defined struct printer.
5361 * dynwind.c (scm_dowinds): Handle fluids on the wind list.

5369 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
5370 SCM_ASSERT: arg comes before pos.
5372 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5374 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
5375 to a list of length zero correctly.
5377 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5379 Supply an `fgets' method for port objects to do fast line i/o.

5391 Mon Jul 21 04:03:42 1997 Gary Houston <ghouston@actrix.gen.nz>
5393 * ioext.h: removed scm_duplicate_port prototype.
5395 * ioext.c (scm_primitive_dup2): return the new file descriptor
5396 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
5398 (scm_fdopen): bug fix: don't try to make port unbuffered until its
5399 stream has been set.
5400 (scm_duplicate_port): deleted, there's now an implementation in
5402 (scm_primitive_dup2): do nothing if newfd == oldfd.
5404 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
5406 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
5409 * ioext.h: new prototypes.
5410 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
5412 * fluids.c (next_fluid_num): don't do
5413 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
5415 * ports.h: prototypes too.
5416 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
5418 * fports.h: prototype too.
5419 * fports.c (scm_evict_ports): moved from ioext.c.
5421 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5423 * ports.c (scm_close_port): return a boolean instead of unspecified.
5424 throw an error if an error other than EBADF occurs.
5426 * filesys.h: scm_close prototype.
5427 * filesys.c (scm_close): new procedure, can close file descriptors
5428 and ports (scsh compatible).
5430 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
5433 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
5435 * fluids.c, fluid.h: New files.
5436 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
5437 (modinclude_HEADERS): Added "fluids.h"
5439 * init.c: Include "fluids.h". (scm_boot_guile_1): Added call to
5440 scm_init_fluids to initialize the fluid machine.
5441 (scm_start_stack): Initialize the fluids of the first root with
5442 scm_make_initial_fluids.

5445 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
5446 (scm_make_root): Call scm_copy_fluids to make fluid bindings
5447 unique for the new root when it has a parent.
5449 * smob.h: Include "libguile/print.h" to make scm_print_state
5452 * dynl.c (free_dynl_obj): New function to free the dynamic object
5453 data. (dynl_smob): Use it.
5454 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
5455 the dynamic object data below the linking of the object to avoid
5456 memory leak when the linking code throws an error. Now the code
5457 leaks a whole dynamically linked library when must_malloc throws,
5458 but that should be much less likely.
5460 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
5462 Changes to compile under gnu-win32, from Marcus Daniels:
5463 * stime.c (tzset): If tzset isn't provided, make it a NOP.
5464 (scm_localtime): Change SCM_EOF to SCM_EOL.
5465 (scm_mktime): Likewise.
5466 * socket.c: Don't include sys/un.h unless autoconf tells
5467 us Unix domain sockets are available.
5468 (scm_fill_sockaddr): Ignore Unix domain code.
5469 (scm_addr_vector): Likewise.
5470 (scm_init_addr_buffer): Likewise.
5471 (scm_socketpair): Don't include unless socketpair was

5474 * scmsigs.c (scm_pause): Don't include unless pause was found
5476 * posix.c (scm_getgroups): Don't include unless support function
5477 was found during autoconf (in this case, getgroups).
5478 (scm_setpwent): For setpwent.
5479 (scm_setegid): For setegid.
5480 * net_db.c (scm_inet_netof): Don't include unless support
5481 function was found during autoconf (in this case, inet_netof).
5482 (scm_lnaof): For inet_lnaof.
5483 (scm_inet_makeaddr): For inet_makeaddr.

5495 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
5496 scm_misc_error, not SCM_EOF.
5498 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
5499 arguments for formatting the error message, not SCM_BOOL_F. I
5500 think this is left over from the (eq? '() #f) days.
5502 * read.c (recsexpr): Give this a dummy definition if
5503 DEBUG_EXTENSIONS isn't #defined.
5505 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
5507 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
5510 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>
5512 * root.c (cwdr_outer_body): Bugfix: Pass `c' instead of `&c' to
5515 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
5517 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
5518 alloca.lo will be included in @LIBLOBJS@. Something better than
5519 this should be possible.
5520 * Makefile.in: Regenerated.
5522 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
5524 * simpos.h: prototype for scm_primitive_exit.
5525 * simpos.c (scm_primitive_exit): new procedure, terminates the
5526 process without unwinding the stack.
5528 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
5530 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
5531 argument and logior its components together, so the user doesn't
5532 have to do this explicitly. Also, if regexp/basic is supplied, then
5533 turn off REG_EXTENDED.
5534 (scm_init_regex_posix): New regexp/basic symbol.
5535 (REG_BASIC): #define this if it is not already present.
5537 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5539 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
5540 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
5541 (CLEANFILES): New target, clean versiondat.h, libpath.h.
5542 (DISTCLEANFILES): New target, clean *.x.
5543 * Makefile.in: Regenerated.

5547 * script.c (scm_compile_shell_switches): Add 1997 to copyright
5548 years in usage message.
5550 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
5551 * Makefile.in: Regenerated.
5553 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
5554 flag; I don't think we support it.
5555 (scm_make_regexp): Make sure the user doesn't pass the
5558 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
5560 (scm_init_regex_posix): Define constants for the REG_mumble flags;
5561 name them according to the SCSH convention: regexp/mumble.
5563 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
5565 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
5567 * Makefile.am (libpath.h): Include the values of all the standard
5568 Makefile directory variables. Print a message, but don't print
5570 (versiondat.h): Print a message, but don't print all the commands.
5571 * load.c: #include "alist.h".
5572 (init_build_info): New function.
5573 (scm_init_load): Call it.
5574 * Makefile.in: Regenerated.
5576 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
5578 * root.c: Establish a reliable catch-all handler for the new root.
5579 After all the Scheme handler function might signal an error too,
5580 and we don't want to lose that.
5581 (cwdr_inner_body): Renamed from cwdr_body.
5582 (cwdr_outer_body): New function, to establish the user's handler,
5583 and pass control to cwdr_inner_body.
5584 (cwdr): Establish the reliable catch-all handler here, and pass
5585 control to cwdr_outer_body.
5586 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
5587 the user's handler through to cwdr_outer_body.
5588 * throw.c (scm_handle_by_message): Move guts into....
5589 (handler_message): New static function.
5590 (scm_handle_by_message_noexit): New function.
5591 * throw.h (scm_handle_by_message_noexit): New prototype.
5593 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
5594 across this. Only works on GCC. Otherwise, we hope for the best.
5595 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
5596 the feeling that real thread systems will not need this...
5598 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
5600 Try to detect when people are using one version of libguile and a
5601 different version of ice-9. People have been skewing things and
5602 sending in bug reports.
5603 * Makefile.am (versiondat.h): New file to generate.
5604 * version.c: #include "versiondat.h", to get version info.
5605 (scm_libguile_config_stamp): New function.
5606 * script.c: #include "version.h".
5607 (scm_compile_switches): Call scm_version to get version number.
5608 * scmconfig.h.in, Makefile.in: Regenerated.
5609 * Makefile.in: Regenerated.
5611 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
5612 primitive definitions under their Scheme names.
5614 * Makefile.am (libguile_la_LDFLAGS): Update library version to
5615 1:2. Helps avoid confusion between installed and uninstalled libs.
5617 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
5620 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
5621 backslash from definition; this should be used like: GDB_INTERFACE;
5623 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5625 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
5626 new port unbuffered until its stream has been set.
5628 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
5630 * ports.h: new prototype.
5631 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
5633 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
5635 Make things compile neatly under Sun's C compiler.
5636 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
5637 * extchrs.c (xmbtowc): Make the second arg a normal char, not
5638 unsigned, because that's what the ANSI function takes.
5639 * extchrs.h (xmbtowc): Corresponding change to prototype.
5640 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
5642 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
5643 argument plain char *.
5644 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
5646 * tag.c (scm_tag): Remove unreachable statement.
5647 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
5648 top of the word, it should be unsigned.
5650 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
5651 is defined, to avoid warnings; it's only used in the
5652 conflict-checking code. Which might go away anyway.
5653 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
5654 conditionals; put the label definition in an #if too, to stifle
5657 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
5658 ChangeLog-threads in the distribution.
5659 * Makefile.in: Regenerated.
5661 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5663 * guile-snarf.in: Changed regexp to support CPPs that insert
5664 whitespace between lexical tokens (which munges the `%%%' snarf
5667 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5669 * load.c (scm_init_load_path): Append $(datadir)/guile to
5670 %load-path, so modules do not have to be installed in Guile's
5671 current version directory.
5673 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
5675 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
5676 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
5677 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
5678 call the sysdep functions with deferred ints.
5679 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
5680 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
5681 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
5684 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
5687 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
5689 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
5691 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
5693 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
5696 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
5698 * eval.c (scm_lookupcar1): New procedure to cope with a race
5699 condition during lookup (when using threads).
5700 (scm_lookupcar): Implement in terms of scm_lookupcar1.
5701 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
5704 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
5706 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
5707 supplied. (Change from Tim Pierce.)
5709 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
5711 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
5712 23:47:01 1997" changelog: Slots are now initialized with `#f' by
5713 default and not `()'. `#f' is the canonical non-value in Scheme,
5716 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5718 * struct.c (struct_printer): New variable that holds a handle on
5719 the Scheme variable *struct-printer*. This variable can be set by
5720 Scheme code to override the printing of structures.
5721 (scm_print_struct): If struct_printer is set, call it. If it is
5722 not set, or returns #f, print the structure in the old fashion.
5723 Include "eval.h" for scm_apply.
5725 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
5727 * struct.c (scm_struct_ref, scm_struct_set_x): Use
5728 scm_struct_i_n_words to get the number of fields, not
5729 -scm_struct_n_extra_words.
5731 On the route to fancier struct printing:
5732 * struct.c (scm_print_struct): New function to print a structure.
5733 Include "genio.h" to support it. This function doesn't do
5734 anything interesting right now, but I think it should be here
5736 * struct.h: Include "print.h" and add prototype for
5738 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
5739 print structures ourself.
5741 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5743 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
5744 before applying the handler in case it doesn't return.
5746 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
5748 * scmsigs.h, async.h: updated.
5750 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
5753 * posix.c (scm_uname): interpret only negative values as an error.
5754 Solaris normally returns a positive value.
5756 * script.c (scm_compile_shell_switches): if we are not going into
5757 an interactive repl, set scm_mask_ints to zero so that asyncs can
5760 * simpos.c (scm_system): don't ignore/unignore signals around
5763 * posix.c (scm_open_pipe): don't ignore/unignore signals around
5766 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
5767 done in boot-9.scm instead.
5769 * scmsigs.c, async.c: Major rewriting of signal handling code.
5770 (scm_sigaction): new procedure.
5771 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
5773 (scm_raise): return unspecified, throw error on failure.
5775 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5777 * regex-posix.c (scm_init_regex_posix): Register the "regex"
5778 feature, to help boot-9.scm decide whether to import the regex
5781 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5783 * eval.c: Include scmconfig.h at the beginning of the file so that
5784 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
5787 * regex-posix.c: #include "_scm.h" before conditionally #including
5788 <regex.h>; the former defines HAVE_REGCOMP.
5790 * regex-posix.c: #include <regex.h> conditionally, so the file is
5791 CPP'able (for dependency scanning) even on systems that don't have
5794 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5796 Add new R4RS-compliant syntax for keywords.
5797 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
5798 regardless of the setting of the `keywords' read option.
5799 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
5800 can be re-read no matter what the setting of the `keywords' read
5803 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
5805 Add support for POSIX regular expressions.
5807 * regex-posix.c, regex-posix.h: New files. (Some code
5808 is taken liberally from rx/rgx.c in the old Guile dist.)
5810 * init.c: Include regex-posix.h.
5811 (scm_boot_guile_1): Call scm_init_regex_posix.
5813 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
5814 Add regex-posix.[ch] sources.
5815 * Makefile.in: Regenerated.
5817 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
5818 to do this automatically? It didn't for me, bleh.)
5820 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
5822 * fports.c (print_pipe_port): New function.
5823 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
5824 latter doesn't even take the right arguments.
5826 * Makefile.am: Increment shared lib revision number. I think
5827 sometimes the uninstalled Guile finds the installed shared lib;
5828 Gord says doing this might help. As things turned out, I can't
5829 say whether it does.
5830 * Makefile.in: Regenerated.
5832 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
5833 passing it as the closure argument to scm_boot_guile. (Bill
5836 * ports.c (print_void_port, putc_void_port, puts_void_port,
5837 write_void_port, flush_void_port, getc_void_port, close_void_port,
5838 noop0): Use ANSI prototypes instead of K&R declarations, so the
5839 initialization of void_port_ptob gets aggressively type-checked.
5840 Fix arguments of print_void_port and write_void_port. (Bill

5874 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
5876 * script.c (scm_find_executable): Use prototype-style definition
5877 here; apparently it's not quite right to have const in a prototype
5878 and then use a K&R declaration. I wonder if stuff like this will
5879 go away if we compile with -Wrequire-prototypes, or whatever that
5880 is... (Bernard URBAN)
5882 * scmhob.h: New text from Bernard URBAN.
5884 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5886 * script.c: Don't #define const on hpux. Configure takes care of
5887 this. (Thanks to Larry Schwimmer.)
5889 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
5890 decide whether to #include <unistd.h>, instead of listing a bunch
5891 of systems. Don't #include stdio twice. Removed dyked-out
5892 definition of scm_find_impl_file.
5894 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5896 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
5897 library version info to 1:0.
5898 * Makefile.in: Regenerated.
5900 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

5904 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
5905 throw.c: Update copyright years; these files have been worked on
5906 significantly in 1997, but only had copyright years for 1996.
5907 Also, change name of copyright holder on some from Mikael
5908 Djurfeldt to Free Software Foundation; he has signed papers
5909 assigning the changes to the FSF.
5911 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
5912 reason not to give the user the option.
5914 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5915 Return #f on end-of-file when scanning table (i.e. when called
5916 with no arguments). Try to catch errors, when we can.
5917 * posix.c (scm_getgrgid, scm_getpwuid): Same.
5919 * script.h (scm_shell_usage, scm_compile_shell_switches): New
5920 external declarations. These are useful.
5922 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
5924 * posix.c: don't include <sys/select.h> or define macros for
5925 select, since they were not used in this file.
5927 * filesys.c (scm_select): make the fifth parameter microseconds,
5928 not milliseconds. let the fourth parameter be either a real value
5929 or an integer or #f. The first, second and third arguments can
5930 now be vectors: the type of the corresponding return set will be
5932 (set_element, get_element): new static procedures.
5934 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
5936 * strports.c (scm_eval_string): New function.
5937 (scm_eval_0str): Trivially re-implemented in terms of
5939 * strports.h (scm_eval_string): New extern decl.
5941 * net_db.c (h_errno): Add extern decl for this.
5943 * fports.c (local_pclose): New function.
5944 (scm_pipob): Use it in the initializer here.
5947 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
5948 Use a meaningful error message when signalling an error. For
5949 this, scm_gethost must check h_errno rather than errno.
5951 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
5953 * Makefile.in: Regenerated, using automake-1.1p.
5955 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5957 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
5958 not SCM_UNSPECIFIED.
5960 * script.c (scm_compile_shell_switches): don't append (quit) if
5962 (scm_shell): call scm_exit_status and exit on the result of the
5965 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
5967 Ensure that shared substrings are handled properly when passed to
5968 a system call or other foreign function. Many thanks to Tim
5970 * symbols.h (SCM_COERCE_SUBSTR): new macro.
5971 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
5972 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
5973 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
5974 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
5975 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
5976 (scm_display_error_message): use RO macros when strings may be RO.
5977 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
5978 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
5979 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
5980 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
5981 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
5982 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
5983 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
5984 scm_strftime), vports.c (scm_make_soft_port): use
5985 SCM_COERCE_SUBSTR to make sure shared substrings are
5988 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5990 * error.c (scm_error): Add newline to error message.
5992 * init.c (scm_init_standard_ports): Doc fix.
5994 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5996 * dynl-shl.c: Completely replaced with new code from Bernard
5999 * script.c (scm_ice_9_already_loaded): New variable.
6000 (scm_compile_shell_switches): Use it.
6002 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
6004 * filesys.c (scm_input_waiting_p): add missing third argument to
6007 * stime.c (scm_localtime): copy the result of localtime before
6008 calling gmtime in case they share a buffer.
6009 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
6012 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6014 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
6016 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
6018 * Makefile.am (check-local): New target, which causes 'make check'
6019 to run gh_test_c and gh_test_repl, with some trivial input.
6020 * Makefile.in: Rgnrtd.
6022 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
6024 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
6027 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
6029 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
6030 sure how this was supposed to work.
6031 (scm_async_click): don't send SCM_TICK_SIGNAL.
6032 (scm_init_async): don't initialize %tick-thunk.
6034 * the following change doesn't affect the Scheme interface:
6035 gc-thunk is called at the end of garbage collection. however it's
6036 no longer implemented by pretending it's a signal.
6038 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
6039 system async corresponding to scm_gc_thunk.
6040 * async.h: declare scm_gc_async.
6041 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
6042 gc-thunk directly, instead of going through a signal handler.
6043 (scm_gc_async): new variable, points to the GC system-async.
6044 (scm_init_async): save the GC async as scm_gc_async instead
6045 of using system_signal_asyncs.
6046 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
6048 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
6050 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
6051 Don't screw up if we're interrupted.
6052 * Makefile.in: Regeneradet.
6054 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
6056 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
6058 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
6059 we're not using AM_INIT_GUILE_MODULE any more.
6060 * Makefile.in: Reneregated.
6062 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
6064 Functions for finding variable bindings, grace à Tim Pierce.
6065 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
6066 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
6068 Get 'make dist' to work again.
6069 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
6070 * Makefile.in: Regenerated, like a surry without a fringe on top.
6072 Changes for reduced Guile distribution: one configure script,
6074 * configure.in, configure: Removed.
6075 * acconfig.h, acinclude.m4: Moved to parent directory, where the
6076 real configure script lives.
6077 * Makefile.in, scmconfig.h.in: Regenerated.
6079 * init.c: #include "script.h", to get prototype for script.c's
6082 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
6084 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
6085 scm_must_malloc, not raw malloc.
6087 * script.c (scm_compile_shell_switches): Dyke out debugging output
6090 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6092 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
6094 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
6095 system has them. Hope this is safe. Previously
6096 sys/timeb.h was included if HAVE_FTIME was defined or if
6097 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
6098 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
6100 * ioext.c (scm_setfileno): add missing third argument to
6101 scm_misc_error call.
6103 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
6105 * eq.c (scm_equal_p): Correctly compare strings of different
6106 varieties. (Thanks to Tim Pierce.)
6108 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
6110 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
6111 #! block comment must occur on a line all by itself.
6113 Move most of the guts of shell command processing into libguile,
6114 so guile.c can be very small (and eventuallly auto-generated. (I
6115 mean, generated mechanically, not self-generated. Hmm.))
6116 * guile.c, script.c, script.h: New source files.
6117 * init.c (scm_boot_guile_1): Call scm_init_script.
6118 * libguile.h: #include "script.h".
6119 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
6120 targets, for new executable.
6121 (libguile_la_SOURCES): Mention script.c.
6122 (modinclude_HEADERS): Add script.h.
6123 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
6124 not dynamic linking is enabled. This is because we're generating
6125 executables now. Move CY_AC_WITH_THREADS call after those, so the
6126 values of cy_cv_threads_libs captures the libs chosen above.
6127 * Makefile.in, configure, aclocal.m4: Regenerated.
6129 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
6130 We don't maintain this interface any more, and it just confuses
6133 * alloca.c: #include <scmconfig.h>, not <config.h>.
6134 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
6135 it'll get included in disties.
6137 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
6139 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
6140 be distributed, because they confuse people.
6141 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
6143 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
6145 * configure.in: check for presence of gethostent (not present on
6146 OpenBSD by default).
6147 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
6148 * configure, scmconfig.h.in: Regenerated.
6150 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
6152 * backtrace.c (scm_backtrace): Split message string across
6153 newlines properly. GCC is more tolerant of this than other
6156 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
6158 Merge threads directory into libguile.
6159 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
6160 threads.h: New source files.
6161 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
6162 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
6164 (modinclude_HEADERS): Add threads.h, coop-defs.h.
6165 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
6166 coop-threads.c.cygnus, coop-threads.h.cygnus.
6167 * configure.in: If we're using threads, include threads.o in
6169 * _scm.h, libguile.h: threads.h lives in this directory now.
6170 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
6171 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
6172 currently used, but brought along for information's sake.
6173 * ChangeLog-threads: log from old 'threads' directory.
6174 * Makefile.in, configure: Rebuilt.
6176 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
6178 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
6181 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
6183 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
6185 Merge GH interface library into libguile.
6186 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
6187 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
6188 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
6189 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
6191 (EXTRA_libguile_la_SOURCES): ... here.
6192 (pkginclude_HEADERS): Add variable, to get gh.h installed.
6193 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
6194 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
6195 New variables, describing how to build the gh test programs.
6196 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
6197 build the test programs, and we probably should have been linking
6198 libguile.la against them all along, to support AIX shared libs.
6199 Add cflags for threads to CFLAGS; add libs for threads to new
6200 variable THREAD_LIBS, used in Makefile.am.
6201 * ChangeLog-gh: log from old `gh' subdirectory.
6202 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
6204 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
6206 * acconfig.h: Undo change of Apr 9; including the definition of
6207 PACKAGE in the guile headers conflicts with applications' own
6209 * scmconfig.h.in: Regenerated.
6211 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

6214 (scm_init_filesys): New symbols for use with fcntl.
6215 * filesys.h: Added prototype.
6217 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
6218 when PROC is receiving no arguments.
6220 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
6222 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
6223 have S_IFSOCK. This is the case under Ultrix.
6225 * posix.c (scm_status_exit_val, scm_status_exit_val,
6226 scm_status_term_sig, scm_status_stop_sig): Modified to work with
6227 Ultrix versions of WIFSTOPPED, etc., which assume that their
6228 arguments are lvalues (hmm).
6230 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
6232 * eval.c: Doc fixes.
6234 * throw.c: Doc fixes; rearranged.
6236 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
6238 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
6240 * acconfig.h: Added entry for PACKAGE.
6241 * scmconfig.h.in: Regenerated.
6243 Changes to work with automake-1.1n, which has better libtool support.
6244 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
6245 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
6247 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
6249 * Makefile.in: Rebuild.
6251 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6253 * stime.c (scm_mktime): take an optional zone argument.
6254 (scm_localtime): check putenv return value.
6255 (scm_strftime, scm_strptime): moved from posix.c. move #include
6257 stime.h, posix.h: update prototypes.
6258 (bdtime2c, setzone, restorezone): new static procedures.
6259 (scm_mktime, scm_strftime): use them.
6260 (scm_strftime): don't call mktime before strftime. Use
6261 filltime for return value.
6262 (filltime): convert NULL zname to #f.
6263 (scm_strptime): return a count of characters consumed, not
6264 the remaining string.
6266 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6268 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
6269 (scm_mktime): likewise.
6271 Uncomment localtime and mktime.
6273 * configure.in: add AC_STRUCT_TIMEZONE.
6275 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
6277 * stime.c (scm_init_stime): don't define ticks/sec.
6278 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
6279 return value problem and is still portable.)
6281 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6283 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
6284 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
6285 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
6286 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
6287 cpp_err_symbols.c): Corresponding changes.
6288 * Makefile.in: Regenerated.
6290 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6292 * posix.c (scm_putenv): don't check HAVE_PUTENV.
6293 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
6294 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
6295 * putenv.c: new file, from sh-utils 1.12.
6297 * posix.c (scm_environ): use malloc in place of scm_must_malloc
6298 since allocation isn't for Scheme objects.
6299 (scm_putenv): copy strings before placing in the environment.
6301 * stime.c (scm_current_time): throw an error if time returns -1,
6302 instead of returning #f.
6303 (scm_get_internal_real_time, scm_get_internal_real_time): use
6304 scm_long2num for return value instead of SCM_MAKINUM.
6306 * stime.h: prototypes updated.
6308 * stime.c (scm_time_in_msec): apparently unused, deleted.
6310 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
6312 * configure.in: check for gettimeofday.
6314 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
6315 which may be more usefully portable than a gettimeofday interface.
6317 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
6319 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
6321 * Makefile.in: Regenerated.
6323 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6325 * stime.c (filltime): recovered static procedure.
6326 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
6329 * posix.h: add prototype for scm_close_pipe, remove prototypes for
6330 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
6332 * posix.c (scm_mknod): split the mode argument into type and perms
6333 arguments, like the extra fields returned by stat.
6335 * fports.c (scm_pipob): set the close, free and print procedures.
6336 (scm_close_pipe): new procedure.
6338 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
6339 define them in boot-9.scm
6341 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6343 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
6344 wan't defined. Don't include fd.h.
6346 * Previously fd.h was regenerated whenever configure was run,
6347 forcing a couple of files to be recompiled.
6349 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
6350 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
6351 Check for _fileno as well as _file.
6353 * ioext.c: don't fd.h.
6354 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
6357 * Change the stratigy for getting information about errno
6358 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
6359 generating lists of symbols during the build process, which will
6360 not always work, include comprehensive lists in the distribution.
6361 To help keep the lists up to date, the "check_signals" and
6362 "check_errnos" make targets can be used.
6364 * configure.in: don't check for a command to extract errno codes.
6365 * Makefile.am: update file lists, remove errnos.list and errnos.c
6366 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
6367 check_errnos targets.
6368 (CLEANFILES): remove errnos.c and errnos.list, add
6369 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
6370 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
6371 * errnos.default: deleted.
6372 * cpp_signal.c: new file.
6373 * cpp_errno.c: renamed from errnos_get.c.
6374 * cpp_err_symbols, cpp_sig_symbols: new files.
6375 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
6376 * error.c (scm_init_error): #include cpp_err_symbols instead of
6378 * posix.c (scm_init_posix): don't intern signal symbols. #include
6381 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
6383 * strop.c (scm_i_index): allow the lower bound to be equal to the
6384 length of the string, so a null string doesn't always give an error.
6386 * posix.h: new prototypes.
6387 * posix.c (scm_status_exit_val, scm_status_term_sig,
6388 scm_status_stop_sig): new functions, as in scsh. They break down
6389 process status values as returned by waitpid.
6391 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
6393 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
6394 configure doesn't know about it.
6396 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6398 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
6400 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
6401 which defines C variables with global linkage.
6403 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6405 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
6408 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
6410 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
6411 has time to check why this doesn't work well with continuations.
6413 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
6415 * Fix shell syntax error; some shells won't tolerate
6416 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
6418 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
6420 * posix.c (scm_uname): throw an error if uname fails instead
6423 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
6425 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
6428 * async.c (scm_ints_disabled): definition moved from error.c.
6430 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6432 * acconfig.h: Removed PACKAGE.
6434 * scmconfig.h.in: Regenerated.
6436 * snarf.h: g++ says it's non-portable not to specify the first
6437 argument in a varargs declaration. I introduced the first
6438 argument by using preprocessor conditionals.
6440 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
6442 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
6443 (scm_freopen): use RO string macros for filename and modes.
6444 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
6446 * posix.c (scm_getgrgid): simplify conversion of name to C string.
6447 (scm_mknod): use RO string macros for path.
6449 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
6450 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
6452 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
6453 use SCM_ROSTRINGP and SCM_ROCHARS.
6455 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6457 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
6460 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
6461 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
6462 support for byte vectors.
6464 * print.c (scm_iprin1): Limit number of vector elements printed
6465 according to pstate->length.
6467 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6469 * backtrace.c (scm_display_error_message): don't segv if message
6472 * error.h: prototype for scm_error_scm.
6474 * error.c (scm_error_scm): new procedure, reimplements scm-error
6475 in C and uses scm_error.
6477 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6479 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
6480 pointer to the Scheme variable read-hash-procedures and intern it
6481 in scm_init_read. Modify scm_read_hash_extend and
6482 scm_get_hash_procedure to use the pointer.
6484 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6486 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
6487 (SCM_KEYWORD_STYLE): defined.
6489 * read.c (scm_read_opts): add a keywords option. This isn't a
6490 boolean option, in case someone wants to add support for DSSSL
6492 Setup scm_keyword_prefix symbol.
6493 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
6495 I've left keyword support disabled by default, since it doesn't
6496 seem to break the module system and it gives R4RS standard behaviour.
6497 It can be reactivated with (read-set! keywords 'prefix).
6499 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6501 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
6502 before constructing arbiter.
6504 * eval.c (scm_m_define): Bugfix: Check that the object is a
6505 closure before setting the procedure property!
6507 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
6509 * ports.c: Removed `ungetc-char-ready?'.
6511 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
6513 * read.c (scm_init_read): intitialise scm_read_hash_procedures
6514 (idea from Mikael: make it a pair so scm_permanent object only
6516 (scm_read_hash_extend): don't call scm_permanent_object.
6517 (ideas from Mikael): if chr is already in the list, replace its
6518 procedure instead of appending it again. If proc is #f, remove
6520 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
6522 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
6524 * gdbint.c (gdb_read): update scm_lreadr usage.
6526 * load.h: update prototypes.
6528 * load.c (scm_primitive_load, scm_read_and_eval_x,
6529 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
6531 * read.h: add prototype for scm_read_hash_extend. Change args for
6534 * read.c (scm_read_hash_procedures): new variable.
6535 (scm_read_hash_extend): new procedure.
6536 (scm_get_hash_procedure): new procedure.
6537 (scm_lreadr): use scm_get_hash_procedure instead of an argument
6538 for extended # processing.
6539 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
6540 scm_read_token): remove case_i, sharp arguments. Change callers.
6542 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
6544 * read.h (SCM_N_READ_OPTIONS): increase to 3.
6545 (SCM_CASE_INSENSITIVE_P): define.
6547 * read.c: add case-insensitive option to scm_read_opts.
6548 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
6549 to determine whether to convert symbol case.
6550 (default_case_i): definition removed.
6551 * read.c (scm_read_token): if case_i, downcase ic before doing
6554 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6556 * configure.in: Added configuration option `guile-debug'.
6557 Configure with --enable-guile-debug if you want a bunch of extra
6558 functions used for debugging when developing Guile.
6560 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
6562 * procs.c (make-cclo): New undocumented debugging procedure: Make
6563 compiled closure with internal procedure PROC and length LENGTH.
6564 Only compiled if GUILE_DEBUG is defined.
6566 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
6568 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
6570 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
6572 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
6573 with 3 or more args internally to the evaluator.
6575 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6577 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
6578 with 3 or more args internally to the evaluator. This is mainly
6579 because we don't want to pass entry and exit points of the
6580 debug support twice, but it also seems to increase the speed of
6581 the evaluator for such calls (e. g. (+ 1 2 3)).
6583 * backtrace.c (scm_display_application): New procedure:
6584 display-application; Set fancy printing parameters individually
6585 for different types of display (backtrace, error, application).
6586 (These should of course be customizable!)
6588 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
6589 clear the CHECK-flags.
6591 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6593 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
6595 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6597 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
6598 from pairs with a GLOC in the car.
6600 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
6601 otherwise `symbol-hash' will behave badly.
6602 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
6603 we get segmentation fault!
6605 * symbols.c: Added #include "weaks.h". New functions:
6606 `builtin-bindings' and `builtin-weak-bindings'. (These will be
6607 moved to an extraneous library when we split libguile.)
6609 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6611 * filesys.c (scm_stat): stat now takes fport arguments too as
6612 documented in the manual.
6614 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6616 * debug.c (scm_single_step): Bugfix: Call continuation with
6617 scm_call_continuation instead of throwing to it.
6619 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
6621 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
6622 argument wasn't declared to be optional.
6624 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6626 * stime.c (scm_init_stime): Add feature "current-time".
6628 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6630 * throw.h: prototype for scm_exit_status.
6631 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
6632 args to derive an exit status. Allows (quit) to work from a
6634 (scm_exit_status): new function.
6637 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6639 * eval.c (scm_deval): Removed some old code.
6640 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
6642 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
6645 * symbols.c (msymbolize): Bugfix: Must initialize property list to
6648 * procs.c: Introduce the existent C function scm_thunk_p at the
6649 Scheme level as well.
6651 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6653 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
6654 used from C to easily lookup the value of a symbol in the current
6657 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6659 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
6660 scm_init_unif in this file. This will also fix a previous problem
6663 * configure.in: Added AM_MAINTAINER_MODE
6665 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6667 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
6670 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6672 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
6673 source files that are not always included in libguile but should
6674 have their dependencies calculated by automake. This variable is
6675 recognized by automake, no further magic is needed.
6676 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
6677 to deal exclusively with *.lo files, as it seems. The *.o files
6678 are built automatically when the corresponding *.lo file gets
6681 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
6683 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
6686 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
6688 * unif.c (scm_array_set_x): minor change to argument error checking.
6690 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
6692 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
6693 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
6694 They should only be included in the library at configure.in's
6696 (libguile_la_LDADD): Include the appropriate .lo files here.
6697 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
6698 so we know when to build them (and their .lo bretheren).
6699 * configure.in (LIBLOBJS): New substituted variable. We let
6700 configure decide which .o files to include in LIBOBJS, and then
6701 put the corresponding list of .lo files in LIBLOBJS. The latter
6702 is what we pass to libtool.
6703 * Makefile.in, configure: regenerated.
6705 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
6707 * symbols.c (scm_sysintern0): New function. Contains the core of
6708 old scm_sysintern but doesn't take a second value argument.
6709 (scm_sysintern): Now uses scm_sysintern0.
6710 (scm_sysintern_no_module_lookup): Renamed to
6711 scm_sysintern0_no_module_lookup and doesn't take a second value
6712 argument any longer.
6714 * symbols.h (scm_sysintern0: Added declaration.
6716 * options.c (scm_init_opts): Use scm_sysintern0 instead of
6717 scm_sysintern when interning option keys. Otherwise we risk
6718 destroying the values of already interned variables.
6720 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
6721 scheme-level boolean (use SCM_NFALSEP).
6723 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
6725 (scm_backtrace): New function. (C version of old function from
6726 boot-9.scm) Motivation: Make it possible to display backtraces
6727 without depending on boot-9.scm. (I'm uncertain if this
6728 motivation is good enough...)
6730 * root.h (scm_root_state): Add member the_last_stack_var.
6731 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
6733 * root.c (mark_root): Mark scm_the_last_stack_var.
6735 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
6738 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
6740 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
6741 1. mark_lazy_catch didn't mark the smob.
6742 2. Both functions above have standard variants:
6743 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
6744 free_lazy_catch --> scm_free0.
6746 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
6748 * throw.c (scm_internal_lazy_catch): New function.
6749 (scm_lazy_catch): Rewritten to use it.
6750 (scm_ithrow): Handle the new lazy catch representation.
6751 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
6752 that doesn't have a jmpbuf is a lazy catch clause.
6753 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
6754 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
6755 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
6757 (scm_init_throw): Register the new lazy-catch smob type.
6758 * throw.h (scm_internal_lazy_catch): decl for new function.
6760 * throw.c (scm_internal_catch): Doc fixes.
6762 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
6763 configure.in. Including this might cause problems if applications
6764 that link against libguile include their own copies of alloca, but
6765 if they're using autoconf, they should be adding libguile to LIBS
6766 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
6767 the copy in libguile, and things will be okay. (I think.)
6769 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6771 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
6773 strop.h: move prototypes too.
6775 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6777 * posix.c (scm_init_posix): don't intern EINTR since it's now done
6780 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
6781 etc. I deleted them from filesys.c long ago, but didn't
6782 notice they were here too (although ineffective since
6783 sys/stat.h wasn't included).
6785 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
6787 * eval.c: Don't define alloca in GCC case. gcc will automatically
6788 use __builtin_alloca if appropriate.
6790 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
6792 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
6793 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
6794 that values of automatic variables are preserved. See comments
6795 for safe_setjmp for details.
6797 Change from Thomas Morgan:
6798 * variable.c: Include eq.h.
6799 (var_equal): New function.
6800 (variable_smob): Use var_equal as the discriminator for variables.
6802 * throw.c (s_throw): Remove extraneous declaration.
6804 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
6805 * eval.c: Add necessary CPP cruft to support that.
6806 * configure, Makefile.in, scmconfig.h.in: regenerated.
6808 Change from Thomas Morgan:
6809 * procprop.c (scm_procedure_properties): Convert the Scheme
6810 boolean returned by scm_procedure_p into a C boolean before using
6811 it as a condition for SCM_ASSERT.
6812 (scm_procedure_property): Likewise.
6814 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
6815 indications of Unixness.
6818 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6820 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
6822 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6824 * read.c (scm_lreadr): use scm_misc_error to improve one of the
6825 "unknown # object" error messages.
6827 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
6828 (scm_i_index) and declare it static. Add a 'direction' argument
6829 to indicate what way the search should go.
6830 (scm_i_index): throw out-of-range error instead of wrong-type-arg
6832 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
6833 strop.h: remove scm_i_index, scm_i_rindex prototypes.
6835 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6837 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
6839 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
6840 to avoid clash with various scsh forks.
6842 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
6844 The following two changes (ramap.c, throw.c) are motivated by the
6845 apparent unportability of forward declarations of static arrays of
6846 the form `static foo bar[];'.
6848 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
6849 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
6851 * throw.c (scm_throw): Moved above scm_ithrow.
6853 * options.h: Removed the extern declarations of scm_yes_sym and
6854 scm_no_sym since these are static.
6856 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6858 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
6860 * Makefile.am: remove AWK=@AWK@.
6861 Add a rule for generating errnos.list.
6862 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
6864 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
6865 don't extract errnos, just set a variable (avoids the
6866 need to recompile error.c just because configure is run.)
6868 * unif.h: update prototypes.
6869 * unif.c (scm_uniform_array_read,write): change the offset and
6870 length arguments to start and end, for consistency.
6872 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
6874 * ioext.h: update prototypes.
6875 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
6876 scm_read_line_x, it's a more general procedure using an
6877 interface from scsh. read-line and read-line! are now defined
6879 Note that the new read-line trims the terminator
6880 by default, previously it was appended to the returned string. An
6881 optional argument specifies how to process the terminator (scsh
6882 compatible). For the old behaviour: (read-line port 'concat).
6883 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
6884 returns a pair, but is converted to multiple values if the scsh
6887 socket.h: update prototypes.
6888 * socket.c (scm_recvfrom): for consistency with other procedures,
6889 take start and end as separate optional arguments.
6890 (scm_recv, scm_recvfrom): don't allow the second argument
6891 to be a size, only a buffer. Change the scheme names to
6892 recv! and recvfrom!. Don't return the buffer.
6894 * ioext.h, posix.h: move prototypes too.
6895 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
6896 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
6897 "read.h" and "unif.h".
6898 * ioext.c: include "chars.h"
6900 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
6902 * dynl.c: The dynamic linking and module registration functions
6903 are now defined even when dynamic linking is not available for the
6904 host system. Some of their functionality can be done without
6905 dynamic linking; when it's really needed, they throw errors.
6907 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
6909 * configure.in: Only define DYNAMIC_LINKING when one of the system
6910 dependent functions is detected.
6911 * dynl.c (scm_dynamic_func): New function to get the address of a
6912 function in a dynamic object.
6913 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
6914 produced by scm_dynamic_func as the thing to call.
6916 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
6918 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
6919 (scm_register_module_xxx, scm_registered_modules,
6920 scm_clear_registered_modules): New functions.
6922 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
6924 * symbols.c (scm_sysintern): Renamed to
6925 scm_sysintern_no_module_lookup.
6926 (scm_sysintern): New function to take the place of the old
6927 scm_sysintern. It uses the current toplevel lookup closure to give
6928 the symbol its value. This is a temporary hack to put packages
6929 like gtcltk into their own module.
6930 (scm_can_use_top_level_lookup_closure_var): New variable to tell
6931 us whether `scm_top_level_lookup_closure_var' has been initialized
6933 * eval.c (scm_init_eval): Set it.
6935 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6937 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
6938 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
6940 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
6942 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
6943 scm_sys_dup): deleted: FD capability will be added to other
6945 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
6946 scm_fd_free, fd_smob, scm_intern_fd.
6947 (scm_open): renamed from scm_sys_open. Return a port instead of
6948 an FD object. Make the mode argument optional.
6949 (scm_sys_create): deleted, it's just a special case of open.
6950 (scm_init_filesys): move interning of constants O_CREAT etc.,
6951 here (were previously using SCM_CONST_LONG macro).
6952 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
6954 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
6955 include "fports.h" and <stdio.h>
6956 (scm_stat, scm_select): don't support FD objects.
6958 * error.h: adjust scm_syserror_msg prototype.
6959 * error.c (scm_syserror_msg): take an extra argument for errno.
6960 Using the global value didn't always work, since it could be
6961 reset by procedure calls in the message or args arguments.
6963 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
6964 I don't understand why the check was there (and what about the
6967 * strop.c (scm_string_copy): allow shared substrings to be copied.
6969 * unif.h: corresponding change to prototypes.
6970 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
6971 recognize two new optional arguments: offset and length. Allow
6972 the port argument to be an integer (file descriptor, for scsh).
6973 Include <unistd.h> for "read" prototype.
6975 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6977 * socket.c: don't include filesys.h.
6979 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6981 * Makefile.am: add AWK=@AWK@ (?)
6983 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6985 Add a rule to generate errnos.c from errnos.
6986 * error.c (scm_init_error): include errnos.c.
6987 * errnos_cnvt.awk: new file, converts the list of errno codes to
6989 * errnos_get.c: new file.
6990 * errnos.default: new file, contains errnos to try if they can't
6991 be extracted from errno.h.
6992 * configure.in: if using GCC, try and extract errno codes from
6996 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6998 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
6999 * Makefile.am: Made libguile into a libtool library.
7000 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
7001 Set libtool_libs to indicate that libguile is a libtool library.
7002 See guile/ChangeLog for details.
7003 * .cvsignore: ignore "*.lo", the libtool library objects.
7005 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
7007 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
7008 use htons in getservbyport argument.
7010 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
7012 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
7013 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
7016 * objprop.c (scm_object_property): No need to take the CDR of the
7017 value returned by scm_object_properties, since Aug 20 change.
7019 * configure.in: When checking for struct linger, #include
7020 <sys/types.h> as well as <sys/socket.h>. I've never known
7021 <sys/types.h> to cause any portability problems, and Solaris's
7022 <sys/socket.h> needs it.
7023 * configure: Rebuilt.
7025 I think the Sun compiler has chosen a perverse way to interpret
7026 ANSI declarations combined with K&R definitions. We'll
7027 appease it a little bit. But when it invades France, we fight.
7028 * print.c (scm_iprlist): Change 'tlr' argument to an int.
7029 * print.h (scm_iprlist): Here too.
7030 * numbers.c (scm_divbigdig): Change definition to match
7031 declaration in numbers.h.
7032 * unif.c (scm_makflo): Change definition to match declaration in
7035 * init.c (scm_boot_guile): Don't return the value of
7036 scm_boot_guile_1. This function doesn't return a value;
7037 scm_boot_guile_1 doesn't return a value (or return at all).
7039 * eval.c (unmemocopy): Add a semicolon to appease the Sun
7042 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
7043 compile. I have a feeling this function is a bad idea anyway ---
7044 one should always test for features, not systems.
7046 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
7047 semicolons. Only pure luck kept this from being noticed earlier.
7049 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
7051 * socket.c (scm_recvfrom): Added missing semicolon.
7053 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
7055 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
7056 the buffer and start and end positions for scsh networking
7059 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
7061 * configure.in: Revert previous change to this file; the problem
7062 is due to transient automake weirdness.
7063 * configure: Rebuilt.
7065 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
7066 PLUGIN/guile.libs. configure generates the latter from the former.
7067 * Makefile.in: Rebuilt.
7069 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
7070 need this if we install scripts, like guile-snarf.
7071 * configure: Rebuilt.
7073 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
7075 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
7077 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
7079 * socket.c (scm_addr_vector): fix faulty scm_listify.
7081 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
7083 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
7084 style block comment is no longer considered an error.
7086 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
7088 * PLUGIN/guile.libs.in: New file.
7089 * PLUGIN/guile.libs: Removed from repository.
7090 * configure.in: Create PLUGIN/guile.libs from
7091 PLUGIN/guile.libs.in. This is for including additonal libraries
7092 needed for dynamic linking.
7093 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
7094 instead of PLUGIN/guile.libs.
7096 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
7098 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
7100 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
7101 occurrences of the given element from the list, not just the
7102 first. This is how the Emacs Lisp functions behave, how the
7103 analogous Common Lisp functions behave, and (I believe) how the
7104 older Maclisp functions worked. I realize that this change may
7105 break code, but it seemed better to break it before the Guile
7108 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
7109 Their prototypes were already present in gc.h, but they weren't
7111 (scm_init_storage): Initialize scm_protects.
7112 * root.c (scm_protects): New element of scm_sys_protects.
7114 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
7116 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
7118 * libguile.h: Added #include "libguile/net_db.h".
7120 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
7121 30 change. That file is only meant for communication between the
7122 configuration process and load.c. If code linked against libguile
7123 wants to get at the paths mentioned in libpath.h, it can call
7124 functions declared in load.h.
7126 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7128 * libguile.h: Removed #include "libguile/fdsocket.h"
7130 * net_db.c: Added #include <sys/socket.h>.
7132 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
7134 * filesys.c (scm_input_waiting_p): use select in preference to
7135 FIONREAD, since the latter doesn't detect EOF.
7136 Throw error if neither select nor FIONREAD available.
7138 * socket.c (scm_connect): take a port, not a fd object.
7139 (scm_fill_sockaddr): throw an error if fam is not recognised.
7140 (scm_bind): use scm_fill_sockaddr.
7141 (scm_listen): take a port, not a fd object.
7142 (scm_accept): take and return a port. return #f in the car if
7143 address can't be got
7144 (scm_sock_fd_to_port): new procedure.
7145 (scm_socket): use scm_sock_fd_to_port.
7146 (scm_addr_vector): throw error if unrecognised address type.
7147 take an extra argument with the calling procedure name.
7148 (scm_getsockname): take a port. return #f if address can't be got.
7149 (scm_getpeername): take a port. return #f if address can't be got.
7150 (scm_recvfrom): take a port. return #f for address component if can't
7152 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
7153 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
7155 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
7157 * throw.c (scm_internal_catch): Make body funcs and handler funcs
7158 use separate data pointers, to allow them to be designed
7159 independently and reused.
7160 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
7161 Renamed from catch_body, catch_handler, and uncaught_throw; made
7163 (struct scm_catch_body_data): Renamed from catch_body_data; moved
7165 (scm_catch): Use the above.
7166 (scm_throw): Don't bother printing a message for an uncaught
7167 throw; we establish a default handler in init.
7168 * throw.h (scm_internal_catch): Prototype updated.
7169 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
7171 (struct scm_body_thunk_data): New structure, used as data
7172 argument to scm_body_thunk.
7173 * init.c (struct main_func_closure): New structure, packaging up
7174 the data to pass to the user's main function.
7175 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
7176 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
7177 scm_internal_catch to establish a catch-all handler, using
7178 scm_handle_by_message. This replaces the special-case code in
7180 (invoke_main_func): Body function for scm_internal_catch; invoke
7181 the user's main function, using the main_func_closure pointer to
7182 decide what to pass it.
7183 * root.c (struct cwdr_body_data): Remove handler_proc member.
7184 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
7185 (cwdr_handler): Removed.
7187 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
7189 * socket.h (SCM_P): update bind prototype.
7190 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
7191 include "feature.h".
7192 (scm_socket): return a port, not a file descriptor object.
7193 include "fports.h" and <unistd.h>
7194 (scm_bind): take a port, not a file descriptor object.
7195 take an extra argument for address args.
7197 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
7198 INADDR_NONE, INADDR_LOOPBACK.
7200 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
7202 * init.c: include net_db.h and not fdsocket.h.
7203 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
7205 * Makefile.am: corresponding changes.
7206 * socket.h: renamed from fdsocket.h, fix names.
7207 * net_db.h: renamed from socket.h, fix names.
7208 * socket.c: renamed from fdsocket.c.
7209 remove _sys from procedure names.
7210 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
7211 add "socket" to features list.
7212 * net_db.c: renamed from socket.c.
7213 remove _sys from procedure names.
7214 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
7215 add "net-db" to features list.
7216 include "net_db.h". don't include <sys/socket.h> or
7219 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7221 * tags.h (scm_tags): Removed comma at end of last enumerator.
7223 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
7225 Don't use GCC extensions to allocate space for debugging frames.
7226 (Here he goes again! Why do we put up with this?!)
7227 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
7228 an scm_debug_info structure, not an in-line array of them. Add
7229 'info' member, to say how many vect elements we've used, for eval
7231 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
7232 a new variable debug_info_end to mark the end of vect, instead of
7233 the address of the 'info' pointer itself.
7234 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
7235 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
7236 (SCM_APPLY): Explicitly allocate space for debug.vect.
7237 * debug.c (scm_m_start_stack): Same, for vframe.vect.
7238 * stacks.c: Adjusted for new debug frame structure.
7239 (RELOC_INFO, RELOC_FRAME): New macros.
7240 (stack_depth, read_frames): Use them, and new scm_debug_frame
7241 element 'info', instead of magically knowing that eval frames have
7242 an info pointer sitting after vect.
7243 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
7245 (scm_init_stacks): Formatting tweaks.
7247 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
7249 Give GCC more control flow information, so it can be sure that
7250 variables aren't used uninitialized.
7251 * error.h (scm_error, scm_syserror, scm_syserror_msg,
7252 scm_sysmissing, scm_num_overflow, scm_out_of_range,
7253 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
7254 scm_misc_error): Tell GCC that these functions never return.
7255 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
7256 out the field type, call abort if SCM_ASSERT returns, to placate
7258 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
7259 scm_wta ever returns. We can't handle this case anyway, and this
7260 gives the optimizer more information.
7261 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
7262 scm_wta ever returns.
7264 In some cases, the code is fine, but GCC isn't smart enough to
7265 figure that out; this usually happens when one variable is only
7266 initialized and used when a particular condition holds true, and
7267 we know that condition will never change within a given invocation
7268 of the function. In this case, we simply initialize the variables
7269 to placate the compiler, hopefully to a value which will cause a
7270 crash if it is ever actually used.
7271 * print.c (scm_iprin1): Initialize mw_pos.
7272 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
7273 * throw.c (scm_ithrow): Initialize dynpair.
7274 * unif.c (scm_uniform_vector_ref): Initialize cra.
7275 * struct.c (init_struct): Initialize prot.
7276 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
7278 * strports.c (scm_eval_0str): Don't return uninitialized garbage
7279 if EXPR contains no expressions.
7281 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
7283 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
7284 cause an infinite loop (???). So much for the algebraic
7285 equivalency of variable-sized arrays and alloca...
7287 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
7289 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
7290 a SCM boolean, not a C boolean.
7292 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
7294 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
7295 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
7296 rules for raising scm_mtrigger. Previously, unfortunate but not
7297 unlikely circumstances could result in almost constant invokation
7298 of the gc. Now, this situations should be less likely, but they
7299 are not prevented completely.
7301 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
7303 * numbers.c (scm_fuck): Procedure removed; looks like old test
7305 * numbers.h: Prototype removed.
7307 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
7309 * debug.h (scm_debug_frame): Change `vect' member from an in-line
7310 array to a pointer, to match my Nov 21 change in eval.c.
7312 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7314 * libguile.h: Added #include "libguile/backtrace.h", #include
7315 "libguile/stacks.h".
7317 * strings.c (scm_string scm_make_string scm_string_ref
7318 scm_string_set_x scm_string_equal_p scm_string_append):
7319 Bugfix according to scm patch from Aubrey Jaffer:
7320 Corrected long-standing
7321 (not (eqv? (integer->char 128)
7322 (string-ref (make-string 1 (integer->char 128)) 0)))
7323 bug found by John Kozak <jk@noontide.demon.co.uk>.
7325 * strports.c, strports.h: Make scm_eval_0str return the value of
7326 the last expression evaluated (previously, it returned void).
7328 * strports.c, strports.h: New function: scm_read_0str. Does what
7331 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7333 * simpos.c (scm_getenv): return #f if string can't be found in the
7334 environment instead of throwing an exception, for compatibility
7335 with numerous other systems.
7337 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
7339 * Makefile.am (.c.x): Use guile-snarf.
7340 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
7342 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
7344 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
7346 * backtrace.c (scm_display_error_message): Made non-static, and
7347 renamed from display_error_message.
7348 * backtrace.h (scm_display_error_message): Added extern decl.
7349 * throw.c (uncaught_throw): Use it to display the error message.
7351 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
7353 * inet_aton.c: Use #if 0, not #ifdef 0.
7355 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
7357 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
7358 to convert the returned value.
7359 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
7360 the offset argument.
7362 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
7364 Add new interface to catch/throw, usable from C as well as
7366 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
7367 (scm_internal_catch): New function, replaces...
7368 (scm_catch_apply): Deleted.
7369 * throw.c (scm_catch_apply): Deleted; replaced with a more general
7370 mechanism which is a bit more code, but can be used nicely from C
7371 and implement the Scheme semantics as well.
7372 (scm_internal_catch): This is the replacement; it's named after
7373 the analogous function in Emacs.
7374 (scm_catch): Reimplemented in terms of the above.
7375 (struct catch_body_data, catch_body, catch_handler): New
7376 functions, used by scm_catch.
7377 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
7378 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
7379 support for new cwdr.
7381 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
7384 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
7386 * acconfig.h: Added DYNAMIC_LINKING symbol.
7387 * configure.in: Add option and checks for dynamic linking.
7388 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
7389 dynl.h: New files for dynamic linking support.
7390 * Makefile.am (libguile_a_SOURCES):
7392 (modinclude_HEADERS): Added "dynl.h".
7393 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
7395 * init.c (scm_boot_guile_1): Call
7396 scm_init_dynamic_linking to initialize dynamic linking support.
7398 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
7400 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
7401 (as we Schemers say). It needs to be global, so that I can tweak
7402 it for the proper operation of unexec.
7403 (scm_boot_guile_1_live): New variable, see above.
7405 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
7407 * guile-snarf.sh: Removed.
7408 * PLUGIN/guile.libs: Added dependency for -lm.
7409 * acinclude.m4: Renamed from aclocal.m4.
7410 * PLUGIN/greet: Removed.
7411 * Makefile.am, aclocal.m4: New files.
7412 * configure.in: Updated for Automake.
7414 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
7416 * eval.c (scm_definedp): Use top_level_lookup_closure_var
7417 and not top_level_lookup_thunk_var.
7419 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
7421 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
7423 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
7425 * eval.c (scm_definedp): Incompatibly changed to be a builtin
7426 Scheme function, instead of syntax. Single argument is now a
7429 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7431 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
7432 scm_ra_divide): Properly terminate statements passed as arguments
7433 to IVDEP macros. (Thanks to Bernard Urban.)
7435 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
7436 with non-constant sizes. (Thanks to Bernard Urban.)
7438 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
7440 It's an "eval closure", not an "eval thunk." A thunk is a
7441 function of no arguments.
7442 * root.h (struct scm_root_state): Renamed
7443 top_level_lookup_closure_var from top_level_lookup_thunk_var.
7444 (scm_top_level_lookup_closure_var): Renamed from
7445 scm_top_level_lookup_thunk_var.
7446 * root.c (mark_root): Uses changed.
7447 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
7448 * init.c (scm_start_stack): Uses changed.
7449 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
7450 Change scheme-visible name to *top-level-lookup-closure* from
7451 *top-level-lookup-thunk*.
7453 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
7455 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
7456 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
7458 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
7460 * gc.c (struct scm_heap_seg_data): Doc fixes.
7462 * gc.c (scm_gc_sweep): Empty all segments' freelists before
7463 sweeping. Then, prepend each segment's free cells to its
7464 freelist, rather than wiping out the old value. (Thanks to Marius
7467 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
7468 scm_check_freelist, scm_debug_newcell): New functions and
7469 variables, for debugging freelist problems.
7470 * pairs.h (SCM_NEWCELL): New debugging version added.
7471 * gc.h (scm_debug_newcell): Added extern declaration, used by
7472 debugging version of SCM_NEWCELL.
7474 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7476 On some systems <libc.h> conflicts with <unistd.h>, and should not
7477 be #included at all.
7478 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
7479 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
7480 * configure.in: Call it.
7481 * posix.c, filesys.c: Use its results to decide whether or not to
7483 * configure, scmconfig.h.in: Rebuilt with autoconf and
7486 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7488 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
7489 pointer to the stdio stream before calling scm_setbuf0, so the
7490 latter will be able to retrieve it. I'm surprised this didn't
7491 segfault earlier. (Thanks to Christopher Lee.)
7493 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7495 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
7498 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7500 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
7501 number of stack narrowing specifier pairs. The first specifier in
7502 a pair controls inner border, the second the outer border. A
7503 number means cut that number of frames, a procedure object means
7504 cut until that object is found in operator position in a frame.
7506 * root.c (cwdr): Bugfix.
7508 * read.c: Recording of positions disabled by default.
7510 * procs.c (scm_closure_p): New function.
7512 * posix.c (scm_tmpnam): New function.
7514 * load.c: Added #include "throw.h".
7515 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
7518 * load.c, load.h (scm_read_and_eval_x): New function.
7520 * eval.c: Renamed debug option "deval" to "debug".
7522 (scm_eval_x): `eval!' is no longer accessible from the scheme
7523 level. Motivation: We can't allow operations which introduce
7524 glocs into the scheme level. Guile's type system can't handle
7525 these as data. Use `eval' or `read-and-eval!' as replacement.
7527 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
7528 SCM_CONSP since this is a macro!; Set vframe.prev to
7529 scm_last_debug_frame instead of 0. In this way we can look
7530 "above" the virtual start stack frame if we wish.
7531 (scm_debug_hang): New function: Useful for debugging Guile in
7532 certain tricky situations. Will probably be removed later...
7534 * debug.h: Changed semantics of debug option "backtrace". This
7535 option now only indicates whether we want automatic backtrace at
7538 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7540 * ports.c: #include "filesys.h"
7541 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
7543 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
7544 Motivation: This is system specific code which is related to file
7545 I/O. It also may use select. Added code by Gary Houston to
7546 detect presence of character in stdio buffers.
7548 * libguile.h: #include "libguile/libpath.h"
7550 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
7551 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
7552 SCM_SITE_DIR; Install libpath.h among the other include files.
7554 * load.c, load.h (scm_sys_package_data_dir): New function.
7556 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7558 * stacks.h: Bugfix: Don't use tail-array length field as stack
7559 length field! This screwed GC.
7561 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7563 * _scm.h: Added #ifndef around definition of macros min and max.
7565 * __scm.h: Added hooks for threads to plugin to in ints protection
7566 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
7567 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
7568 the main code in these macros duplicated and spread over multiple
7569 files. Renamed SCM_THREADS_SWITCHING_CODE ->
7570 SCM_THREAD_SWITCHING_CODE.
7572 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
7574 * snarf.h: New file.
7575 * guile-snarf.sh: New file.
7576 * Makefile.in (inner_h_files): Added snarf.h
7577 (ancillary, install, uninstall, distclean): Added actions for
7579 (.c.x): Use guile-snarf.
7580 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
7581 (gen_c_files): Note that these depend on guile-snarf.
7582 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
7583 now in "snarf.h". Added #include "snarf.h" to get them.
7584 * libguile.h: Added #include "snarf.h".
7585 (Patches applied and tweaked by Jim Blandy.)
7587 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7589 * socket.c: Use K&R style declaration for 'close'; the GNU coding
7590 standards suggest against providing prototypes for system
7591 functions. Thanks to Greg Troxel.
7593 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
7595 * strports.c (scm_eval_0str): New function.
7596 #include "read.h", to get prototype for scm_read.
7597 * Makefile.in (strports.o): Update dependencies.
7598 * strports.h: New prototype.
7600 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
7601 scheme name from "int?" to "integer?". It seems to do the job.
7602 * numbers.h: Rename prototype too.
7603 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
7606 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
7607 scm_num_eq_p): Rename these according to R4RS conventions: call
7608 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
7609 to making libguile R4RS compliant without ice-9...
7611 * load.c (scm_sys_search_load_path): Search for files under all
7612 extensions listed in the %load-extensions variable. If FILENAME
7613 is absolute, return it unchanged, without searching the load path.
7614 (scm_loc_load_extensions): New variable, pointing to
7615 %load-extensions' value cell.
7616 (scm_init_load): Initialize it, and the value it points to.
7617 (scm_primitive_load_path): Improve error reporting.
7619 * load.c (scm_loc_load_hook): New variable, pointing to value cell
7620 of new Scheme variable %load-hook.
7621 (scm_primitive_load): Apply %load-hook to filename.
7623 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
7625 * configure.in: add tests for figuring out whether buffered data
7626 is available in a FILE structure, which is needed by char-ready.
7628 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
7631 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
7632 exceptions using misc_error instead of syserror. It seems a bit
7633 odd to throw an exception if a string can't be found in the
7634 environment, but it's consistent with open-file, stat etc.
7635 (simpos.h): remove sys_ from getenv.
7637 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
7638 occurs, throw an error instead of returning errno. Return value
7640 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
7642 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
7644 * filesys.c (scm_stat2scm): derive file type and permissions from
7645 the stat mode and append them to the returned vector.
7646 There isn't much overhead in doing this and it avoids the need to
7647 work with S_IRUSR et al. in Scheme.
7648 Define symbols scm_sym_regular etc.
7649 (scm_init_filesys): don't intern S_IRUSR etc.
7651 * load.c: change s_try_load and s_try_load_path to s_primitive_load
7652 and s_primitive_load_path.
7654 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
7656 * error.h: don't declare error symbols. prototype for scm_misc_error.
7658 * stackchk.c (scm_stack_overflow_key): defined here instead of in
7661 * error.c: use SCM_SYMBOL to set up error keys.
7662 scm_misc_error: new procedure.
7664 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
7666 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
7667 between `#!' and `!#' is ignored.
7668 (skip_scsh_block_comment): New function.
7670 * feature.c (scm_set_program_arguments): New argument, FIRST.
7671 * feature.h: Update prototype.
7672 * init.c (scm_boot_guile_1): Pass new argument to
7673 scm_set_program_arguments.
7675 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
7677 * init.c (scm_start_stack): Don't initialize scm_progargs here.
7678 (scm_boot_guile): Call scm_set_program_arguments here, later than
7679 the old initialization.
7681 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
7682 initialization procedure.
7683 - Delete in, out, err arguments; there are other perfectly good
7684 ways to override these when desired.
7685 - Delete result argument; this function shouldn't ever return.
7686 - Rename init_func argument to main_func, for less confusion.
7687 - Delete boot_cmd argument; main_func is more general.
7688 -Add 'closure' argument, to help people pass data to main_func
7689 without resorting to global variables.
7690 - Abort if reentered; don't bother returning an error code.
7691 - Call scm_init_standard_ports to set up the default/current
7692 standard ports; no need to pass them to scm_start_stack.
7693 - Remove code to evaluate the boot_cmd, and start the repl; let
7694 the user do something like that in main_func if they want.
7695 - Remove code to package up a return value; main_func can do any
7697 - Call exit (0), instead of returning.
7698 (scm_start_stack): Don't initialize the I/O ports here; that's
7699 weird. Delete in, out, err arguments. Move guts to
7700 scm_init_standard_ports, scm_stdio_to_port.
7701 (scm_init_standard_ports): New function, to set up current and
7702 default standard ports.
7703 (scm_start_stack, scm_restart_stack): Make these static.
7704 * init.h (scm_boot_guile): Adjust declaration.
7705 (scm_start_stack, scm_restart_stack): Remove externally
7706 visible declarations for these.
7707 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
7709 * fports.c (scm_stdio_to_port): New function. Its guts used to be
7710 written out several times in scm_start_stack.
7711 * fports.h: New declaration for the above.
7713 * feature.c (scm_set_program_arguments): New function.
7714 * feature.h: New declaration for the above.
7716 * ports.c: Formatting tweak.
7718 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
7720 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
7721 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
7722 for obtaining the address of a car or cdr field. Motivation:
7723 &SCM_CXR make assumptions about the internal structure of the
7726 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
7727 Motivation: see SCM_CXRLOC.
7729 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
7730 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
7731 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
7732 Motivation: Safer use. Some other macros are defined in terms of
7733 these operations. If these are defined using the SCM_SETCXR
7734 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
7735 to inefficiency and an <e1> with side-effects could potentially
7736 break. Also, these particular operations are heavily utilized in
7737 the garbage collector. In unoptimized code there will be a
7740 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
7741 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
7742 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
7743 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
7744 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
7745 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
7746 vports.c: Cleaned up use of pairs: Don't make any special
7747 assumptions about the internal structure of selectors and
7748 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
7749 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
7750 (Among other things, this change makes it easier to build Guile
7751 with certain compilers which have problems with casted lvalues.)
7753 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7755 * stacks.c: Improve selection of relevant stack frames when making
7756 a stack object. Introduce one level of indirection in the stack
7757 object to make it possible to "narrow" to a certain region of the
7758 stack. This facilitates making use of more clever algorithms (not
7759 implemented) for selecting relevant frames and gives a cleaner
7760 design since selection of frames can be done independently of
7761 extraction of frames from the real stack.
7762 (scm_stack_id): Also take #t as argument which means look at
7765 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
7766 Turn n_tail into an integer directly representing current number
7767 of frames in stack. Add field tail.
7769 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
7771 * debug.c (scm_make_memoized): Made it available at scheme level.
7772 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
7773 SCM_NIMP before applying heavier predicates in argument checking.
7774 (scm_local_eval): Also take memoized object as argument.
7776 * backtrace.c (scm_display_error): Just a safety measure: Stacks
7777 aren't created with zero length, but should such a strange
7778 creature suddenly turn up...
7780 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
7782 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
7783 `del', for the sake of C++ compilers. (Patch applied by JimB.)
7785 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
7787 * variable.c (scm_make_variable): Make the name hint optional, as
7789 (anonymous_variable_sym): Renamed from variable_sym. All uses
7792 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
7793 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
7794 of scm_primitive_load_path was also changed to
7795 "primitive-load-path", from "%try-load-path". Callers changed.
7796 We'd like to respect the convention that a function named
7797 "try-mumble" should behave just like the function called "mumble",
7798 but return #f instead of signalling some error.
7799 * load.h: Rename prototypes.
7801 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7803 * print.c (make_print_state, grow_print_state), print.h: Modified
7804 the print state representation: Don't use a tail array for
7805 recording of circular references. Resizing of the print state
7806 structure invalidates the print state pointer. To avoid passing
7807 around an indirect print state reference to all printing
7808 functions, we instead let the print state reference a resizable
7811 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7813 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
7814 Don't crash when passed an improper list terminated by a
7815 non-immediate value.
7817 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
7819 Allocate data for structures on an eight-byte boundary, as
7820 required by the tagging system.
7821 * struct.c (alloc_struct): New function.
7822 (scm_make_struct, scm_make_vtable_vtable): Call it.
7823 * struct.h (scm_struct_n_extra_words): Bump to 3.
7824 (scm_struct_i_ptr): New "field".
7825 * gc.c (scm_gc_sweep): When we need to free the data, use the
7826 information stored by alloc_struct to find the beginning of the
7827 block allocated to the structure, so we can free it.
7829 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7831 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
7834 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
7835 (scm_debug_info): New member: id.
7837 * stacks.c: Stacks are now represented as structs; Stacks have an
7838 id given to them by `start-stack'.
7839 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
7841 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
7842 Changed stack representation.
7844 * debug.c (scm_procedure_name): Try procedure property `name' for
7845 compiled closures aswell.
7847 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
7849 * eval.c: scm_i_name moved to gsubr.c
7850 (scm_m_define): Record names of all kinds of procedure
7851 objects. (Earlier, only closures were recorded.)
7853 * procprop.h: Added declaration of scm_i_name.
7855 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
7856 (scm_make_gsubr): Record names of compiled closures.
7858 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7860 * debug.c, debug.h: Removed obsolete code.
7862 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
7863 stacks.c: Renamed regs --> scm_contregs.
7865 * print.c (scm_free_print_state): Cleanup print state before
7866 returning it to pool. It is better to do it here than in
7867 scm_prin1 since scm_prin1 is called often.
7869 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
7870 s_set_source_property_x): Check that first argument is a pair or a
7873 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
7874 scm_i_line, scm_i_column and scm_i_breakpoint global.
7876 * init.c: Added #include "backtrace.h" and #include "stacks.h".
7877 (scm_boot_guile_1): Added calls to scm_init_backtrace and
7880 * debug.h: Added debug object smob declaration and macro
7883 * configure.in: Build with backtrace.o and stacks.o if debug
7886 * Makefile.in: Added entries for new files: backtrace.c,
7887 backtrace.h, stacks.c and stacks.h.
7889 * symbols.c (scm_sym2ovcell): Fixed documentation.
7891 * _scm.h (min, max): Added.
7893 * async.c: Moved `min' macro to _scm.h.
7895 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
7896 SCM_BACKTRACE_INDENT.
7898 * eval.c: Added new debug options `maxdepth' and `indent'.
7900 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
7902 * print.h: Added selector SCM_PRINT_STATE.
7904 * print.c: New functions: scm_make_print_state,
7905 scm_free_print_state.
7907 * print.h: Added declarations for scm_make_print_state,
7908 scm_free_print_state.
7910 * debug.c (scm_m_start_stack): New acro.
7912 * debug.h: Small cleanup.
7914 * init.c (scm_boot_guile_1): Moved scm_init_debug below
7917 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

7937 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
7938 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
7939 declare functions with prototypes. (Patch thanks to Marius
7942 More prototype-related changes from Marius Vollmer:
7943 * gdb_interface.h: Wrapped header file in #ifdef/#endif
7944 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
7945 * ports.h (ptobfuns): Added prototypes. This means some casting in
7947 * fports.c: Added casts for initializations, since the functions
7948 are defined to take FILE * as their stream argument, not SCM.
7949 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
7950 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
7951 to `char *str_data' to conform to prototype.
7953 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7955 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
7957 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
7959 * stime.c, stime.h: use SCM_P method.
7961 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7963 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
7964 be given at least two arguments. Insist that lst's last element
7965 be a list, but don't make any requirements of its predecessors.
7967 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7969 * eval.c (scm_nconc2last): Revert last change; there seems to be
7970 other stuff going on here.
7972 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7974 * eval.c (scm_nconc2last): Make sure that each element of lst
7975 (which is a list of argument lists, except for the tail) is a
7976 proper list, i.e., finite and terminated by '().
7978 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7980 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7983 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7984 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7987 * vectors.c (scm_make_vector): Fill vectors with the undefined
7988 value, to help make Guile Scheme code more portable to other
7991 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7992 * symbols.h, tags.h: Doc fixes.
7994 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
7996 * async.c (scm_take_signal): Doc fixes.
7998 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
8000 * numbers.c (scm_divbigint): When the remainder is zero, we don't
8001 want to subtract it from the modulus; we just want to leave it
8004 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
8006 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
8009 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
8011 * throw.c (scm_catch_apply): Finished implementation of
8014 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
8016 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
8018 (scm_init_filesys): set "i/o-extensions" feature.
8021 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
8023 * Makefile.in (root.o): Correct dependencies.
8025 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
8027 * Makefile.in: Added dependency entry for root.o.
8029 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
8030 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
8032 * init.c (scm_start_stack): Set initial root continuation number
8035 * procs.c: New function: scm_thunk_p.
8037 * procs.h: Added declarations of scm_thunk_p.
8039 * root.c: Renamed `call-with-new-root' -->
8040 `call-with-dynamic-root'.
8041 (cwdr): Removed allocation of new root state. This should be done
8042 separately by use of scm_make_root.
8043 (scm_apply_with_dynamic_root): New function: Does what it
8044 sounds like. Needed when spawning threads.
8046 * root.h: Added member last_debug_frame to root state.
8047 Added #include "libguile/debug.h"
8049 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
8050 arguments. The motivation is that code in root.c needs catch
8051 functionality, and we want to avoid code duplication.
8052 New functions: scm_catch, scm_lazy_catch. These are wrappers for
8053 scm_catch_apply. scm_lazy_catch is intended to introduce catch
8054 handlers that run without popping the stack into the dynwind
8057 * throw.h: Added prototypes for scm_catch_apply and
8060 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8062 * root.h (scm_root, scm_set_root): Decouple thread support details
8063 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
8064 SCM_SET_THREAD_LOCAL_DATA.
8066 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
8067 and tortoise scanning loop.
8069 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
8071 * Makefile.in: Rebuild dependencies.
8073 * libguile.h: #include "libguile/print.h" before "smob.h", since
8074 the latter uses the print_state structure.
8076 * throw.c (scm_ithrow): Use the correct variable when checking to
8077 see if a given element of scm_dynwinds is a valid catch.
8079 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
8080 structure, abort; don't just silently ignore the garbage.
8082 * _scm.h: #include "print.h" here, since it seems to be used just
8084 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
8085 strports.c, unif.h: Don't #include "print.h".
8087 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8089 * feature.h (scm_loc_features): Removed external declaration.
8090 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
8092 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8094 * feature.c (scm_init_feature): Added threads feature (needs to be
8095 initialized here, since features doesn't exist when
8096 scm_init_threads is called).
8098 * libguile.h: Added #include "libguile/../threads/threads.h".
8099 (This is a kludge to get thread support working. This should be
8102 * configure.in, acconfig.h: Added flags for thread support.
8104 * scmsigs.c: Define `signal' to be `pthread_signal' if using
8107 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
8108 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
8111 * _scm.h: Added conditional #include "threads.h"
8113 * __scm.h (SCM_ASYNC_TICK): Added call to macro
8114 SCM_THREADS_SWITCHING_CODE.
8116 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
8117 allocate the basic dynamic root object.
8118 (scm_boot_guile): Added call to scm_init_root.
8120 * root.c, root.h: Added root smob.
8121 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
8122 functions: Implements dynamic roots mostly according to spec in
8123 SCM manual. Main difference is that the second argument is a
8124 throw handler rather than an error "thunk".
8126 * root.h: Added declaration of scm_init_root.
8128 * root.c: Added #include "genio.h", #include "smob.h", #include
8129 "pairs.h", #include "throw.h", #include "dynwind.h", #include
8131 (scm_init_root): Added #include "root.x".
8133 * throw.c: Added #include "stackchk.h"
8134 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
8135 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
8136 can be used in scm_call_with_new_root; Added reenabling of stack
8137 checking when catching a throw.
8139 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
8141 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
8143 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
8144 element is not found, as per R4RS.
8146 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
8148 * list.c: Doc fixes throughout.
8150 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
8152 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
8153 declare the char * to be const. Avoids a warning in rgx.c.
8155 * ports.h: spelling fix.
8157 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
8160 * load.c (scm_sys_try_load_path): throw an error if file not found
8161 (like it says it in NEWS).
8163 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
8165 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
8166 PROPS slot to '(), not #f; it's an empty alist.
8168 * throw.h, throw.c: Use SCM_P instead of #if hair.
8170 Remove special support for uncaught throws; see throw.c for
8172 * throw.c (uncaught_throw): New function.
8173 (scm_ithrow): Call uncaught_throw if we don't find a throw
8174 target; don't mess with scm_bad_throw_vcell.
8175 (scm_bad_throw_vcell): Variable deleted.
8176 (scm_init_throw): Don't initialize it.
8178 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
8181 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
8183 * numbers.c (scm_istr2int): If the number is short (as most
8184 numbers are), just call scm_small_istr2int to deal with it.
8185 (scm_small_istr2int): New function, created by un-#ifdefing the
8186 non-bignum version of scm_istr2int and renaming it.
8188 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
8190 * load.c (scm_sys_try_load): don't check whether value returned
8191 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
8192 Change the Scheme name from %try-load to primitive-load.
8194 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
8195 Can avoid passing a message, allowing it to be derived in the
8196 error handler (e.g., if we want to throw to the key both from
8199 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
8201 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
8202 references now have a new appearance which is more compact and
8203 also gives a clue about what the target of the reference is.
8204 By setting parameters in the print state, more fancy printing can
8205 be achieved. This is used by the (not yet commited) backtrace
8208 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
8210 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
8213 * print.c: Added #include "struct.h". Removed function
8216 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
8217 scm_iprin1. Removed prototype for scm_prlist.
8219 * arbiters.c (prinarb),
8220 async.c (print_async),
8221 debug.c (prindebugobj, prinmemoized),
8222 eval.c (prinprom, prinmacro),
8223 filesys.c (scm_fd_print, scm_dir_print),
8225 mallocs.c (prinmalloc),
8226 numbers.c, numbers.h (scm_floprint, scm_bigprint),
8227 smob.h (scm_smobfuns),
8228 srcprop.c (prinsrcprops),
8230 unif.c, unif.h (scm_raprin1, rapr1),
8231 variable.c (prin_var): Changed argument `int writing' to
8232 `scm_print_state *pstate'.
8234 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
8235 that it will be called before scm_init_print.
8237 * print.c (scm_prin1): Print states are now allocated when calling
8238 scm_prin1 and then passed around to all printing functions as an
8239 argument. A cache `print_state_pool' enables reuse of print
8241 (scm_make_print_state): New function.
8242 (scm_iprin1): Adaption to print states.
8243 (scm_iprlist): An initial "hare and tortoise" scan brings down
8244 time complexity to O (depth * N). (Better time complexity will be
8245 achieved when the printing code is completely rewritten.)
8247 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
8249 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
8250 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
8251 it gets done whether or not the cache variable has a value.
8253 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8255 Distinguish #f and ().
8256 * __scm.h: #undef SICP.
8257 * pairs.h (SCM_EOL): Delete this definition, equating it with
8259 * tags.h (SCM_EOL): Give it a new definition here; I think I found
8260 the value it used to have. Doc fixes, too.
8262 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
8264 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
8265 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
8266 Lord's implementation of structs, allowing for tail arrays as
8267 described in the manual. Also fixed some bugs. (Both the interface
8268 and the implementation should be improved.)
8270 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
8272 * print.c, print.h: Closures now print like #<procedure foo (x)>.
8273 People who whish to see the source can do `(print-enable 'source)'.
8274 Removed #ifdef DEBUG_EXTENSIONS.
8276 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
8278 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
8279 integer (assuming for now accepting an integer is a good thing).
8281 * error.c, fports.c: replace use of %S in lgh_error args with %s.
8282 %S will be used instead for write'ing arguments.
8284 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
8285 asserts. fix a few other asserts.
8286 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
8287 scm_uniform_vector_ref, scm_array_set_x,
8288 scm_dimensions_to_unform_array): change args in
8289 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
8290 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
8291 scm_substring_fill_x): likewise.
8292 gsubr.c (scm_gsubr_apply): likewise.
8293 eval.c (SCM_APPLY): likewise.
8295 * eval.c (4 places): replace scm_everr with lgh_error or
8298 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
8299 scm_memory_error): new procedures.
8300 scm_everr: deleted. can use scm_wta, dropping first two args.
8301 scm_error: convert NULL subr to SCM_BOOL_F.
8303 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
8306 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
8309 * error.c, error.h: new error keys: scm_arg_type_key,
8310 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
8312 scm_wta: reimplement using lgh_error instead of scm_everr.
8314 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
8316 * gdbint.c: scm_lread now has one more argument.
8318 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
8319 scm_port_\1; Added mutator scm_set_port_filename_x (used when
8320 loading source from non-file ports, which, e. g., happens when
8321 using the Emacs interface).
8323 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
8326 * read.c: Added code for recording of positions of source code
8327 expressions; New functions: recsexpr, scm_lreadrecparen;
8328 _scm_make_srcprops --> scm_make_srcprops
8329 (scm_flush_ws): Removed updating of positions counters. This work
8330 is already done by scm_gen_getc
8332 * read.h: Added prototype for scm_lreadrecparen
8334 * print.c: Added #include "alist.h"
8336 * eval.c: Added #include "hash.h"
8338 * eq.c: Added #include "ramap.h"
8340 * options.c: Documentation fixes.
8342 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
8343 (scm_init_srcprop): Adjusted size of initial source-whash. Name
8344 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
8345 --> scm_make_srcprops
8347 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
8348 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
8349 function calls in the definition of the whash access macros.
8351 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
8353 * init.c (scm_boot_guile): Add level of indirection to
8354 scm_boot_guile_1() to ensure that stack base pointer is properly
8355 initialized. There was no guarantee that variable i was the
8356 highest/lowest variable on stack (i.e. the call frame of
8357 scm_boot_guile was not completely protected from gc).
8359 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
8361 * ports.h (scm_port_table): put back file_name, it will be used to
8362 support debugging. Undo related changes in fports.c, ioext.c,
8365 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
8367 * ports.h (scm_port_table): remove file_name member for now, it seems
8369 * fports.c (scm_open_file): don't set file_name in PTAB.
8370 (prinfport): don't use file_name in PTAB.
8371 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
8372 * ports.c (scm_add_to_port_table): don't intialize file_name.
8373 (scm_port_file_name): remove for now.
8374 * gc.c (scm_gc_mark): don't mark PTAB file_name.
8376 * fports.h (scm_mkfile): prototype deleted.
8377 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
8379 * debug.c, unif.c: use scm_out_of_range instead of
8380 wta for range errors (ASSERT still needs work).
8382 * error.c, error.h (scm_out_of_range): new procedure.
8384 * error.c, error.h (scm_out_of_range_key): new key.
8386 * posix.c (scm_sync): #else was missing.
8388 * error.c, error.h: append _key to names scm_num_overflow and
8391 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
8392 of consing an empty list.
8393 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
8394 of macros, saves code and string space.
8395 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
8396 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
8397 lower case. Rename scm_syserror_m to scm_syserror_msg.
8398 error.h: prototypes for new procedures.
8400 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
8402 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
8404 * error.c, error.h: setup scm_num_overflow key.
8406 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
8407 Remove definition of SCM_OVSCM_FLOW.
8409 * fports.c (scm_open_file): use SCM_SYSERROR_M.
8411 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
8412 explicit message and args.
8414 * error.c, error.h, __scm.h: change system_error_sym to
8417 * error.c (system_error_sym): remove leading %% from the Scheme name
8420 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
8422 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8424 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
8425 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
8426 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
8427 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
8428 renamed. (These were introduced by unsupervised name
8431 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8433 * print.c: Added code for detection of circular references during
8434 printing. (init_ref_stack, grow_ref_stack): New functions. Added
8435 a hook for printing of closures (accessible via print options).
8436 This leads to a split of calls to scm_iprin1 into two classes:
8437 elementary print operations (e. g. the code which prints a smob)
8438 still use scm_iprin1 while top level calls (like scm_display) use
8439 scm_prin1. scm_prin1 begins by clearing the data structure used
8440 to record reference information.
8442 * print.h: Added declarations of scm_prin1 and scm_prlist.
8444 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
8446 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
8448 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
8450 * error.c (err_head): scm_iprin1 --> scm_prin1
8452 * debug.c: Adjusted header comment.
8456 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
8458 * strerror.c: Doc fix.
8460 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8462 * gdbint.c (gdb_read): Now possible to run during GC.
8463 (unmark_port, remark_port): New functions.
8465 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
8467 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
8468 of allocating a new string object. Also, increase size by
8469 the factor 2 instead of 1.5.
8471 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
8473 * __scm.h (SCM_P): Corrected to run under traditional C.
8475 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
8478 * async.c: Calls to scm_sysintern corrected.
8480 * async.h (scm_async_clock): Redundant declaration removed.
8482 * continuations.c (scm_dynthrow): Redundant declaration removed.
8484 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
8485 Definition typos corrected.
8487 * debug.h: Missing declarations of functions in debug.c added
8490 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
8491 Missing declarations to functions in eval.c added.
8493 * filesys.c: Possibly uninitialized variable rv.
8495 * gc.h (scm_object_addr, scm_unhash_name): Missing
8496 declarations of functions defined in gc.c added.
8498 * genio.c: Possible typos str_data -> wstr_data. ???
8500 * genio.c: Possibly unintended shadowing of local variable
8501 `int c' (gotos out of scope of inner `c'). ???
8503 * init.c: Uninitialized `SCM last' may be used.
8505 * ioext.h: (scm_sys_isatty_p): Typo.
8507 * list.h (scm_list_head): Missing prototype for function in
8510 * numbers.c (scm_two_doubles): Changed from extern to static
8511 (is used only within numbers.c).
8513 * numbers.h: Repeated declarations removed.
8515 * ports.h (scm_close_all_ports_except): Declaration for the
8516 function defined in ports.c added.
8518 * posix.h: Missing declarations added.
8520 * procs.h (scm_make_subr_opt): Missing declaration added.
8522 * socket.h (scm_sys_gethost): Missing declaration added.
8524 * socket.h: Redundant declarations removed (they are in fdsocket.h).
8526 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
8527 Missing declarations added.
8529 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
8531 * struct.c: Uninitialized variable `SCM answer' may be used.
8533 * unif.c (l2ra): Declaration prototype.
8535 * unif.c (scm_array_equal_p): Dummy definition removed (it is
8536 defined in ramap.c).
8538 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
8539 Redundant declarations removed (they are in ramap.h).
8541 * variable.h (scm_make_udvariable,
8542 scm_make_undefined_variable): Declaration corrected to
8543 correspond variable.c.
8545 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
8546 Missing declarations added.
8548 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
8550 * Makefile.in (distclean): Don't forget to delete fd.h.
8552 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
8554 * fd.h.in, tags.h: Trivial cleanups.
8556 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
8557 marksweep.h just declared functions from gc.c.
8558 * gc.h, libguile.h: Don't #include "marksweep.h".
8559 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
8560 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
8561 dependencies updated.
8563 * libguile.h: Don't #include "files.h"; it's been deleted.
8565 * files.c (scm_sys_delete_file): Moved to filesys.c.
8566 File is now empty; deleted.
8568 * filesys.c: scm_sys_delete_file is now here. Remove
8569 #if's; they seem to rely on remnants of an old portability
8570 regimen. If the problems come up again, solve them properly,
8571 using autoconf. Specifically: Don't test M_SYSV, and #define
8572 remove to be unlink if it's #defined; don't use remove just
8573 because HAVE_STDC_HEADERS is #defined.
8574 * filesys.h: Add declarations for scm_sys_delete_file.
8575 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
8576 files.o, files.h, files.c, and files.x.
8577 * init.c: Don't #include "files.h", and don't call scm_init_files.
8579 Use SCM_P instead of PROTO; the latter intrudes on the user's
8581 * params.h: Deleted; definition of SCM_P moved to...
8582 * __scm.h: ... here, where it replaces PROTO macro.
8583 * libguile.h, smob.h: Don't #include "params.h".
8584 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
8585 smob.h: Fix prototypes accordingly.
8586 * Makefile.in: Update dependencies.
8587 (inner_h_files): Remove params.h.
8589 * gc.c: #include "gc.h"; every module should include its header,
8590 to let the compiler cross-check the declarations against the
8593 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
8594 simpos.h: #include "libguile/__scm.h".
8596 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
8598 * init.c: Don't forget to #include smob.h and init.h.
8599 * Makefile.in: Dependencies updated.
8601 * smob.h: Use PROTO instead of #if __STDC__.
8603 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
8605 * __scm.h: Doc fixes.
8607 * __scm.h, libguile.h: Use "quotes" in the #includes, not
8608 <angles>; this allows `make depends' to work properly.
8610 * libguile.h: #include smob.h and pairs.h before the others; they
8611 define typedefs used by other headers.
8613 C files should #include only the header files they need, not
8614 libguile.h (which #includes all the header files); the pointless
8615 recompilation was wasting my time.
8616 * Makefile.in (all .o dependency lists): Regenerated.
8617 * libguile.h: Don't try to get a definition for size_t here...
8618 * __scm.h: Do it here.
8619 * _scm.h: Since this is the internal libguile header, put things
8620 here that all (or a majority) of the libguile files will want.
8621 Don't #include <libguile.h> here; that generates dependencies on
8622 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
8623 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
8624 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

8723 * stackchk.h: #include "libguile/debug.h",
8725 * print.h, read.h: #include "options.h", since everyone who uses
8726 either of these files will need that.
8728 * smob.h: #include "ports.h", "genio.h", and "print.h", since
8729 anyone who uses this file will need them to define the smob
8730 printing functions. Also, get markers.h, since people will need
8731 to #define the mark functions.
8733 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
8734 * ports.h: ... to here.
8736 * ports.h (scm_port_table_size): Explicitly give type as 'int';
8737 don't rely on archaic C default type rules.
8739 * fports.h: #include "libguile/ports.h", since you need that in
8740 order to parse this.
8742 * genio.h: #include "libguile/print.h", because you need that to
8743 parse this; don't bother #including "ports.h", since print.h gets
8746 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
8748 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
8749 this; it's now a reference to an element of *scm_root.
8751 * debug.h: Don't #include "options.h"; the compiler won't be able
8752 to find that once the headers are installed; instead, #include
8753 "libguile/options.h".
8754 * gc.h: Same, with marksweep.h.
8755 * mbstrings.h: Same, with symbols.h.
8756 * scmhob.h: Same, with _scm.h.
8757 * smob.h: Same, with params.h.
8759 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
8760 C files; there's no need for this, and it forces recompilations
8763 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
8765 * error.c (scm_error): declare scm_error_callback.
8767 * error.h: prototype for scm_error_callback.
8769 * __scm.h: define lgh_error.
8770 (SCM_SYSERROR): redefine using lgh_error.
8772 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
8774 * error.c (scm_error): new procedure.
8776 * error.h: prototype for scm_error.
8778 * Makefile.in (install): install scmconfig.h from the current

8796 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8798 * Makefile.in (.c.x): Simplify; there's no need to run this rule
8799 when scmconfig.h doesn't exist.
8801 * load.c (scm_sys_try_load): Correct spelling.
8803 * feature.c (scm_loc_features): Make this static.
8805 * Makefile.in (libpath.h): Omit trailing slash from path. We
8806 shouldn't require it of users, so why put it here?
8808 Move code to initialize and search %load-path from ice-9 to C
8809 code, so we can use the load-path to find the ice-9 boot code;
8810 this makes it easier to run Guile without installing it. See
8811 corresponding changes in guile/Makefile.in.
8812 * feature.c: Move stuff concerned with the load path to load.c.
8813 (scm_compiled_library_path): Deleted.
8814 Don't #include libpath.h here.
8815 * feature.h: Don't mention scm_compiled_library_path.
8816 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
8817 <sys/stat.h>, and <unistd.h> (if present).
8818 (R_OK): #define if the system hasn't deigned to.
8819 (scm_loc_load_path): New variable.
8820 (scm_init_load_path, scm_sys_search_load_path,
8821 scm_sys_try_load_path): New functions.
8822 (scm_init_load): Initialize scm_loc_load_path to point to the
8823 value cell of the Scheme %load-path variable.
8824 * load.h: Add declarations for scm_sys_search_load_path,
8825 scm_sys_try_load_path.
8826 * init.c: Call scm_init_load_path.
8827 * Makefile.in (feature.o, load.o): Dependencies updated.
8829 * load.c, load.h: Rewrite using PROTO macro.
8831 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8833 * gc.c (scm_cellp): New function: C predicate to determine if an
8834 SCM value can be regarded as a pointer to a cell on the heap.
8836 * gc.h: Added declaration of scm_cellp.
8838 * gdb_interface.h: New file: The GDB interface header from the GDB
8841 * gdbint.c: New file: GDB interface.
8843 * gdbint.h: New file: GDB interface.
8845 * libguile.h: Added #include <libguile/gdbint.h>.
8847 * init.c (scm_boot_guile): Added scm_init_gdbint.
8849 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
8850 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
8851 found if object files and source are kept separate).
8853 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
8855 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
8857 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
8859 * configure.in: Don't substitute the values of TCL_SRC_DIR and
8860 TK_SRC_DIR; they're not relevant any more.
8862 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
8863 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
8865 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
8867 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
8868 search path, so we can find the <libguile/MUMBLE.h> headers.
8870 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
8872 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
8873 implicit in the .c.o rule.
8874 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
8877 Put the library path in a header file, instead of passing it on
8878 the command line in every compilation.
8879 * Makefile.in (libpath.h): New target.
8880 (feature.o): Depend on libpath.h.
8881 (clean): Delete libpath.h.
8882 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
8883 * feature.c: ... #include "libpath.h" here.
8884 * .cvsignore: Ignore libpath.h.
8886 Don't install the unwashed masses of Guile header files in the
8887 main #include path; put most of them in a subdirectory called
8888 'libguile'. This avoids naming conflicts between Guile header
8889 files and system header files (of which there were a few).
8890 * Makefile.in (pkgincludedir): Deleted.
8891 (innerincludedir): New variable; this and $(includedir) are enough.
8892 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
8893 (installed_h_files): Divide this up. Now this variable lists
8894 those header files which should go into $(includedir) (i.e. appear
8895 directly in the #include path), and ...
8896 (inner_h_files): ... this new variable says which files appear in
8897 a subdirectory, and are referred to as <libguile/mumble.h>.
8898 (h_files): List them both.
8899 (install): Create innerincludedir, not pkgincludedir. Put
8900 the installed_h_files and inner_h_files in their proper places.
8901 (uninstall): Corresponding changes.
8902 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8903 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8904 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
8905 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
8906 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
8907 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8908 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8909 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8910 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8911 vports.h, weaks.h: Find __scm.h in its new location.
8912 * __scm.h: Find scmconfig.h and tags.h in their new locations
8913 (they're both "inner" files).
8915 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
8917 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
8919 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
8921 * posix.c: Doc fixes.
8923 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
8925 * socket.c: Don't include a prototype for inet_aton; just use a
8926 K&R style declaration, to avoid warnings but minimize the chance
8927 of conflicts with the system.
8929 On NextStep, <utime.h> doesn't define struct utime, unless we
8930 #define _POSIX_SOURCE before #including it.
8931 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
8932 * acconfig.h: New comment text for above CPP symbol.
8933 * configure.in: Call it.
8934 * posix.c: #define _POSIX_SOURCE if it seems necessary.
8936 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
8938 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
8939 testing for __EMX__.
8941 * posix.c: #include <libc.h>, if it exists.
8943 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
8944 don't even know if the latter exists.
8946 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
8947 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
8948 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
8950 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
8952 (scm_init_posix): Use them when initializing the Scheme constants
8955 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
8957 * Makefile.in (libdir, includedir, bindir): Use the
8958 autoconf-supplied values, instead of deriving them ourselves.
8959 (pkgincludedir, datadir, pkgdatadir): New variables.
8960 (install, uninstall): Put the header files in a special
8961 subdirectory, not in the main search path.
8963 * Makefile.in (ALL_CFLAGS): Provide the proper value for
8964 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
8966 * Makefile.in (IMPLPATH): Deleted; never used.
8968 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
8969 on the Tcl/Tk source any more.
8970 (INCLUDE_CFLAGS): Remove references to the above.
8972 * Makefile.in (version.o): Corrected dependencies.
8974 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8976 * libguile.h: #include "version.h"
8978 * init.c (scm_boot_guile): Call scm_init_version.
8979 * gscm.c (gscm_run_scm): Call scm_init_version.
8981 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8982 GUILE_VERSION): AC_DEFINE these.
8983 (acconfig.h): #undef the above symbols.
8985 * Makefile.in (libobjs): Add version.o.
8986 (installed_h_files): Add version.h.
8987 (c_files): Add version.c.
8988 (gen_c_files): Add version.x.
8989 (version.o): New rule.
8990 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
8991 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
8992 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
8993 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
8994 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
8995 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
8996 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
8997 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
8998 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
8999 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
9000 weaks.o): Add version.h to dependency lists.
9001 (markers.o): Remove duplicate rule.
9003 * version.h: New file.
9005 * version.c: New file.
9007 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
9009 * symbols.c (scm_strhash): scm_downcase is now a function, not an
9010 array; use it appropriately. Since GCC is quite happy to
9011 subscript functions, it never warned us about this; we should use
9012 -Wpointer-arith in the future. I guess we never tested
9015 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
9017 * socket.c: Doc and copyright fixes.
9019 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
9021 * debug.c: Fixed and improved gdb support.
9023 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
9025 * socket.c: Added declaration of inet_aton to avoid compiler
9026 warning. (Hope this solution is correct.)
9028 * stime.c: Added declaration of ftime. (This is missing in
9031 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
9033 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
9035 * Makefile.in (c_files): add strerror.c.
9037 * strerror.c: new file from Emacs' sysdep.c.
9038 maybe configure should also check for sys_errlist.
9040 * configure.in (AC_REPLACE_FUNCS): add strerror.
9042 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
9044 * debug.c (scm_init_debug): Added initialization for
9045 scm_evaluator_traps.
9047 * debug.h, debug.c: Various name changes.
9048 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
9049 "debug-options-interface". See commentary in options.c.
9051 * options.h, options.c: Options now have documentation strings.
9052 Also added a long explanatory commentary.
9054 * eval.c, print.h, print.c, read.h, read.c: Modifications to
9057 * gscm.c, init.c, root.c, throw.c: Bug fixes:
9058 last_debug_info_frame is now updated in all cases.
9060 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
9063 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
9065 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
9066 Added option STACK_CHECKING.
9068 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
9070 * Makefile.in: Added {debug,options,srcprop}.{h,c}
9072 * __scm.h: Removed symbols for debugging support.
9074 * acconfig.h: Added symbols for debugging support.
9076 * configure.in: Added user option for debugging support.
9077 --enable-debug will include the debugging code into libguile.a.
9079 * continuations.c (scm_make_cont): Enlarged the #if 0 around
9080 scm_relocate_chunk_to_heap.
9082 * debug.c: New file: low-level debugging support. It also
9083 includes support for debugging with gdb. (The extensions to gdb
9084 are written by Per Bothner at Cygnus.)
9086 * debug.h: New file: low-level debugging support.
9088 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
9089 argument pairs. Extensive modifications to the debugging
9090 evaluator. Added "SECTION:" commentaries to clarify what happens
9091 when, during double compilation. Renamed EVALIMP --> EVALIM.
9092 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
9093 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
9094 the beginning of the file. New procedure: scm_unmemocopy.
9095 Added some global state variables needed by the debugging
9096 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
9097 check_entry, check_apply, check_exit, debug_options and
9098 evaluator_traps. New acro: undefine.
9100 * eval.h: Renamed EVAL --> XEVAL.
9102 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
9103 --> scm_make_weak_key_hash_table.
9105 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
9106 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
9108 * libguile.h: Conditionally include debug.h
9110 * objprop.c (scm_object_properties, scm_set_object_properties_x):
9111 scm_object_properties shouldn't return handle. `handle' now gets
9112 initialized in scm_set_object_properties_x. scm_object_properties
9113 doesn't any longer create an entry in scm_object_whash.
9115 * options.c: New file: handling of run time options.
9117 * options.h: New file: handling of run time options.
9119 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
9121 * print.c: New procedure: scm_print_options
9123 * print.h: Defines for print options.
9125 * read.c: New procedure: scm_read_options
9127 * read.h: Defines for reader options.
9129 * root.h: Added scm_source_whash among scm_sys_protects.
9131 * srcprop.c: New file: source properties.
9133 * srcprop.h: New file: source properties.
9135 * throw.c (jbsmob): Jump buffers are now correctly allocated.
9136 (Bug found by A. Green.)
9138 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
9140 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
9142 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
9144 * libguile.h: #include "objprop.h"; I guess this was forgotten.
9146 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
9147 and should be called by the final client.
9149 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
9151 * gc.h: Use the PROTO macro when declaring functions.
9152 * gc.c: Use the PROTO macro when declaring static functions.
9153 Remove the CPP hair around function definitions.
9155 * gc.c (scm_init_storage): Initialize scm_asyncs.
9157 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
9158 preprocessor symbol; "__scm.h" is where it might get #defined.
9159 * __scm.h: Similar: #include <scmconfig.h> before testing
9162 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
9164 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
9166 * init.c (scm_boot_guile): Add init_func argument; call
9167 (*init_func) instead of calling scm_appinit; it's ucky to
9168 hard-code names for the user's procedures.
9169 * init.h (scm_boot_guile): Adjust declaration.
9171 * __scm.h (PROTO): New macro, for declaring functions with
9174 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
9175 eliminate all the __STDC__ conditionals.
9176 (scm_boot_guile): Add declaration.
9177 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
9178 Remove __STDC__ conditionals around function definitions; the
9179 declarations in init.h will provide the same information, more
9182 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
9183 complain about it in the error message; the error message is
9184 adequate without that note, and there's nothing the user can do
9187 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
9189 * Makefile.in (ancillary): Drop def.sed.
9191 * posix.c (scm_init_posix): Use numeric values, rather than
9192 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
9193 F_OK. The symbols aren't available on some systems, and I'm
9194 pretty sure their values are fixed by common widespread practice.
9195 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
9197 More functions unavailable on some systems.
9198 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
9199 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
9201 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
9202 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
9203 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
9204 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
9205 stub that signals an error as the #else.
9207 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
9209 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
9211 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
9213 * unif.c: include ramap.h.
9215 * read.c (endif): case_insensative_p renamed case_insensitive_p.
9217 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
9219 * ports.c: include sys/ioctl.h.
9221 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
9223 * configure.in: check for sys/ioctl.h.
9225 * ports.c: include <malloc.h> not "malloc.h".
9227 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
9229 * fports.c: remove ttyname and tmpnam declarations.
9231 * posix.c: fewer ttyname declarations.
9233 * fports.c: include <string.h> not "string.h".
9235 * init.c, ioext.c: include string.h and unistd.h.
9237 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
9239 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
9240 genio.c, simpos.c, vports.c: include string.h.
9242 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
9244 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
9246 (scm_addr_buffer_size): change type from scm_sizet to int.
9247 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
9248 from scm_sizet to int.
9250 * error.c: include unistd.h.
9252 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
9255 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
9257 * __scm.hd, def.sed: deleted.
9259 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
9261 Changes for NeXT, suggested by Robert Brown.
9262 * configure.in: Call AC_TYPE_MODE_T.
9263 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
9264 NeXT. Put header file list in alphabetical order.
9265 * configure, scmconfig.h.in: Regenerated.
9266 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
9268 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
9271 * acconfig.h: New file, providing documentation for the CPP
9272 symbols defined in configure.in
9273 * acconfig-1.5.h: Removed; superceded by the above.
9275 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
9277 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
9279 * fports.c (scm_open_file): don't return #f, throw error.
9281 * ioext.c (fileno): renamed from %fileno.
9282 (soft-fileno): deleted.
9284 * ports.c (scm_port_revealed): don't need to check for -1 from
9286 (scm_set_port_revealed_x): return unspecified, not #f.
9288 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
9290 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.

9302 (installed_h_files): Put in alphabetical order.
9303 Remove duplicate entries for markers.h and unif.h.

9305 (ancillary): Renamed from anillery; all uses changed. Remove
9306 PLUGIN; it's a directory, and needs special treatment in dist-dir.

9309 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
9311 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
9312 every if must have an else, or else the whole command has a
9313 non-zero exit code whenever the if's condition is false.

9380 matter so long as it is non-0 (got rid of "* 4").
9382 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
9384 * gscm.h: gscm_mkarray eliminated (presumably was not being used
9385 since its definition was bogus).

9391 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
9393 * ports.c: removed functions relating to the mapping between ports
9394 and descriptors. (That stuff is unix-specific and should be collected
9395 in a separate library).

9402 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
9403 handled correctly (SCM_FREEP was applied to them) -- test for
9404 NIMP. Keys in weak hash tables were spuriously (though harmlessly)

9572 initialization to fix a race condition.
9574 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

9601 The weird symbol syntax is also a bit bogus (emacs doesn't quite
