1 1999-12-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3 * feature.c (s_scm_add_hook_x): Call scm_wrong_type_arg instead of
4 scm_misc_error when add-hook! is passed a procedure of wring
5 arity. (Thanks to Greg Harvey.)
7 1999-12-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
9 * macros.c (scm_make_synt): Use scm_make_subr_opt to make the
10 transformer subr. (Thanks to Bill Schottstaedt.)
12 1999-12-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
14 * objects.c (scm_class_of): Bugfix: Inserted missing SCM_CDR
15 setting struct table class.
17 Sun Dec 19 10:22:34 1999 Greg J. Badros <gjb@cs.washington.edu>
19 * threads.c, mit-pthreads.c, list.c, coop.c: Remove K&R
20 prototypes; just use ANSI C prototypes. I'm not sure how
21 mit-pthreads.c ever compiled -- it still doesn't for me, but the
22 normal make procedure does not try to build it anyway (even
23 --with-threads I get the other threads code building) so I'm not
26 Sat Dec 18 16:58:34 1999 Greg J. Badros <gjb@cs.washington.edu>
28 * tags.h (SCM_CONSP, SCM_NCONSP): Define these in terms of
29 SCM_SLOPPY_CONSP and SCM_SLOPPY_NCONSP. (SCM_CONSP) Define this
30 in terms of SCM_SLOPPY_NCONSP instead of repeating the
33 * symbols.h (SCM_SLOPPY_SUBSTRP, SCM_SUBSTRP): Added former, and
34 define latter in terms of sloppy variant.
36 * strings.h (SCM_SLOPPY_STRINGP, SCM_STRINGP): Added former, and
37 define latter in terms of sloppy variant.
39 * scm_validate.h (SCM_MAKE_VALIDATE): Added this macro to factor
40 out the commonality of the various basic SCM_VALIDATE_foop
41 macros. Use SCM_MAKE_VALIDATE macro where possible. Fix
42 SCM_VALIDATE_INT_COPY to not use scm_num2ulong -- that does
43 coercion to an integer which is more advanced than desired and
44 SCM_NUM2ULONG provides that functionality. Use SCM_ASSERT_RANGE
45 appropriately for the various _MIN, _MAX, _RANGE macros. Drop
46 some superfluous "SCM_NIMP &&" where possible. Eliminate obsoleted
47 SCM_VALIDATE_NIMCONS (SCM_VALIDATE_CONS now does the NIMP test as
48 part of its SCM_CONSP test).
50 * socket.c, ports.c, pairs.c, list.c, lang.c, async.c: Use
51 SCM_VALIDATE_CONS, not obsoleted SCM_VALIDATE_NIMCONS.
53 Sat Dec 18 15:33:05 1999 Greg J. Badros <gjb@cs.washington.edu>
55 * dynl.c: Added #include "scm_validate.h"
57 Sat Dec 18 15:22:10 1999 Greg J. Badros <gjb@cs.washington.edu>
59 * alist.c, chars.c, dynl.c, net_db.c, numbers.c, unif.c: Use
60 SCM_NUM2ULONG instead of scm_num2ulong; SCM_NUM2LONG instead of
61 scm_num2long; SCM_WTA instead of scm_wta. Only done for when
62 FUNC_NAME was used as an argument of the macro and the formal
63 argument name was the explicit argument in the old function call.
64 These were just missed in my first pass of changes.
66 1999-12-18 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
68 * guile-doc-snarf.in (filename): Strip path to source dir before
69 touching the .x-files.
71 1999-12-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
73 * debug.c (scm_reverse_lookup): Bugfix: Reinserted SCM_NIMP.
75 * eval.c (SCM_CEVAL): Removed check for unbound slot in
76 SCM_IM_SLOT_REF. (This is now handled in a smarter way in GOOPS.)
78 1999-12-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
80 * tags.h (SCM_SLOPPY_NCONSP, SCM_SLOPPY_CONSP): New macros.
81 (SCM_ECONSP): Version which doesn't mix && and || without
83 (SCM_NECONSP): Bugfree version.
85 Fri Dec 17 12:09:11 1999 Greg J. Badros <gjb@cs.washington.edu>
87 * tags.h (SCM_ECONSP, SCM_NECONSP): Fix these macros to have the
88 SCM_NIMP test integrated into an || clause that I'd missed before
89 and was causing a segfault in the regression tests.
91 * symbols.h (SCM_ROUCHARS): Make cast be to (unsigned char *), not
92 (char *); fixes a problem reported by the regression test
95 * ports.c: Fixed a couple of arg/number mismatches in
98 Now passes the (not-comprehensive) guile-modules test-suite again!
100 Thu Dec 16 12:41:22 1999 Greg J. Badros <gjb@cs.washington.edu>
102 * coop-threads.c: Remove K&R function headers.
104 * scm_validate.h: Added SCM_VALIDATE_THREAD.
106 * *.c: Remove SCM_NIMP(X) when it is an extraneous pre-test given
107 that SCM_FOOP macros all now include SCM_NIMP in their expansion.
108 This simplifies lots of code, making it far more readable.
110 Wed Dec 15 19:45:14 1999 Greg J. Badros <gjb@cs.washington.edu>
112 * *.h: Use SCM_NIMP(X) && in all the FOOP macros.
114 * *.[ch]: Use do { ... } while (0) idiom in macros that expanded
117 Tue Dec 14 10:53:14 1999 Greg J. Badros <gjb@cs.washington.edu>
119 * snarf.h: Put SCM_PROC and SCM_PROC1 back in for
120 backward-compatibility of packages that use Guile. Internally
121 Guile should not use them, though. (Maybe enforce this with a new
122 -DBUILDING_GUILE compile-time flag?).
124 Tue Dec 14 09:41:01 1999 Greg J. Badros <gjb@cs.washington.edu>
126 * backtrace.c (scm_set_print_params_x): Renamed from
129 * guile-doc-snarf.in: Use guile-snarf.awk, not
130 guile-doc-snarf.awk. Pass the basename of $filename
132 * load.h: Added prototypes for scm_sys_library_dir,
135 * load.c (scm_sys_library_dir, scm_sys_site_dir): Added these
136 functions, and took out the old scm_library_dir, scm_site_dir,
137 scm_pkgdata_dir. Now the primitives are %package-data-dir
138 (already existed), %library-dir, and %site-dir.
140 * debug.c: Use SCM_MISC_ERROR when possible instead of using
141 s_scm_* in a scm_misc_error() call.
143 * Makefile.am: Use guile-snarf.awk, not guile-doc-snarf.awk. Make
144 using guile-doc-snarf send stdout to $@ to create the .x file like
147 * guile-snarf.awk.in: Added.
149 * guile-doc-snarf.awk.in: Removed (sorry to back out a recent
150 commit; if we're going to switch to guile-snarf I figure it makes
151 sense to get this right now-- I'd already had the change in my
152 working copy when the below commit happened).
154 1999-12-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
156 * guile-doc-snarf.awk: Removed.
158 * guile-doc-snarf.awk.in: Added.
160 * ports.c (s_scm_pt_member): Fixed validation.
162 * guile-doc-snarf.in (filename): Use basename in order to strip
165 * debug.c (scm_make_iloc, s_scm_proc_to_mem): Added missing
167 (scm_memcons, scm_memcons, mem_to_proc): Renamed function name
170 * backtrace.c (set_print_params_x): Fixed GUILE_PROC macro.
172 * tags.h (SCM_UNBOUND): New iflag which is needed for some time to
173 mark the unboundness of a GOOPS slot. (Added now in order to
174 correct a oversight. Should probably be removed again and
175 replaced with SCM_UNDEFINED when the corresponding code in GOOPS
178 * print.c (scm_isymnames): Added printed representation for
181 * eval.c (SCM_CEVAL): Bugfix: Added check for unbound slot in
184 Mon Dec 13 17:23:22 1999 Greg J. Badros <gjb@cs.washington.edu>
186 * strings.c: Fixed mistaken default value in
187 scm_make_shared_substring; thanks Eric Moore!
189 Mon Dec 13 16:29:13 1999 Greg J. Badros <gjb@cs.washington.edu>
191 * guile-doc-snarf.awk: Use sub instead of gsub in ^ anchored
192 replacement for docstrings. Fixes problem Ryan Yeske observed
193 with using mawk on his system. Thanks Ryan!
195 Mon Dec 13 13:30:06 1999 Greg J. Badros <gjb@cs.washington.edu>
197 * guile-doc-snarf.in: Do not echo to stdout since the output now
198 gets stuck directly in the files instead of redirected from
201 * guile-doc-snarf.awk: Escape a literal ) -- thanks Ryan
202 Yeske. Use print instead of printf to prime the .x file since
203 AIX's cpp has problems with #include-ing empty files (according to
204 the old guile-snarf.in file).
206 Sun Dec 12 19:39:00 1999 Greg J. Badros <gjb@cs.washington.edu>
208 * Makefile.am: Fix ETAGS_ARGS to recognize GUILE_PROC,
209 GUILE_PROC1. Build guile-procedures.txt, and add that file to
212 * load.c: Added `pkgdata-dir', `site-dir', `library-dir'
215 * guile-doc-snarf.awk: Drop trailing space when no arguments:
216 e.g., "(foo )" is now "(foo)".
218 * *.c, alist.c: moved all the documentation for primitives from
219 guile-doc/ref/{appendices,posix,scheme}.texi into the source code.
220 This leaves about half of the primitives undocumented. Also, all
221 the markup is currently still texinfo. I don't have a problem
222 with texinfo per se, but the markup is not very descriptive or
225 Sun Dec 12 16:50:26 1999 Greg J. Badros <gjb@cs.washington.edu>
227 * scm_validate.h: Drop the SCM_DOCSTRING_SNARF for turning off
228 SCM_VALIDATE macros; the SCM_VALIDATE macros should be checked for
229 argument mismatches (along with the FUNC_NAME macro checking) by a
230 static tool that runs directly over the .c files.
232 * snarf.h: Handle SCM_REGISTER_PROC better when snarfing. The
233 docstring is still missing from the .doc file; it just gives the
234 name of the C function that gets called instead.
236 * guile-doc-snarf.awk: Be sure to touch the output files to help
237 make out. Also handle SCM_REGISTER_PROC better, and change the
238 output format slightly.
240 Sun Dec 12 15:33:40 1999 Greg J. Badros <gjb@cs.washington.edu>
242 * snarf.h: Drop SCM_PROC, SCM_PROC1. Added extra output for
243 guile-doc-snarf script.
245 * guile-doc-snarf.in, guile-doc-snarf.awk: New, simple doc
246 extraction system. Builds foo.x, foo.doc from foo.{c,cc}.
247 There are dependencies between these files and snarf.h. This
248 replaces guile-snarf.
250 * guile-snarf.in: Drop everything after $$$ for the new snarf.h
251 macros. This is obsoleted by guile-doc-snarf, but kept here for
252 now for good measure.
254 * Makefile.am: Added guile-doc-snarf, guile-doc-snarf.awk to
255 bin_SCRIPTS. Added .doc to SUFFIXES, and give rule for creating
256 .doc files to use guile-doc-snarf. Update the rule for creating
257 .x files to use guile-doc-snarf.
259 Sun Dec 12 12:31:38 1999 Greg J. Badros <gjb@cs.washington.edu>
261 * *.c: Finish replacing K&R style prototypes with ANSI C
264 * eval.c: Make scm_m_mody's 3rd argument be a const char *, not a
265 char *. ANSI prototypes caught this.
267 * strorder.c: Use GUILE_PROC1 for the couple SCM_PROC1 expansions
270 * scm_validate.h: Use SCM_BOOLP for validating bools. Do not
271 expand macros if SCM_DOCSTRING_SNARF.
273 Sun Dec 12 11:23:22 1999 Greg J. Badros <gjb@cs.washington.edu>
275 * *.c, srcprop.h: Use SCM_BOOL(f) instead of (f? SCM_BOOL_T:
276 SCM_BOOL_F) and use SCM_NEGATE_BOOL(f) instead of (f? SCM_BOOL_F:
279 Sun Dec 12 11:08:51 1999 Greg J. Badros <gjb@cs.washington.edu>
281 * boolean.h: Added SCM_BOOL, SCM_NEGATE_BOOL, SCM_BOOLP to here,
284 * scm_validate.h: Moved above out into boolean.h, fix typo in
285 SCM_VALIDATE_NIM macro.
287 Sun Dec 12 10:29:12 1999 Greg J. Badros <gjb@cs.washington.edu>
289 * *.c, scm_validate.h: Use SCM_VALIDATE_NIM, not SCM_VALIDATE_NIMP
290 (none of the other validate macros have the trailing P).
292 Sun Dec 12 10:07:29 1999 Greg J. Badros <gjb@cs.washington.edu>
294 * scm_validate.h: Added the FSF copyright to the top.
296 * strings.c: Use SCM_ASSERT_RANGE in a couple of places instead of
297 SCM_ASSERT w/ SCM_OUT_OF_RANGE.
299 Sat Dec 11 18:34:12 1999 Greg J. Badros <gjb@cs.washington.edu>
301 * Makefile.am: Added scm_validate.h to modinclude_HEADERS.
303 * *.c: Pervasive software-engineering-motivated rewrite of
304 function headers and argument checking. Switched SCM_PROC,
305 SCM_PROC1 macros to be GUILE_PROC, GUILE_PROC1 (may change names
306 later, but was useful to keep old versions around while migrate)
307 that has docstrings and argument lists embedded in the GUILE_PROC
308 macro invocations that expand into a function header. Use lots of
309 new SCM_VALIDATE_* macros to simplify error checking and reduce
310 tons of redundancy. This is very similar to what I did for Scwm.
312 Note that none of the extraction of the docstrings, nor software
313 engineering checks of Scwm is yet added to Guile. I'll work on
314 that tomorrow, I expect.
316 * chars.c: Added docstrings for the primitives defined in here.
318 * snarf.h: Added GUILE_PROC, GUILE_PROC1. Added
319 SCM_REGISTER_PROC to be like old SCM_PROC, though old SCM_PROC
320 still remains for now. Changed naming convention for the s_foo
321 string name of the primitive to be s_scm_foo for ease of use with
324 * scm_validate.h: Lots of new SCM_VALIDATE macros to simplify
325 argument checking through guile. Maybe some of these should be
326 folded into the header file for the types they check, but for now
327 it was easiest to just stick them all in one place.
329 1999-12-10 Greg Harvey <Greg.Harvey@thezone.net> (applied --12/10/99 gjb)
331 * smob.c (scm_smob_prehistory): initialize allocated smob
333 * tags.h: new tag: scm_tc16_allocated
335 * gc.c (scm_gc_for_newcell): set the car of the new cell
336 to scm_tc16_allocated
337 * pairs.h (SCM_NEWCELL): set the car to scm_tc16_allocated
338 (scm_gc_mark): mark allocated cells.
340 1999-12-09 Greg J. Badros <gjb@cs.washington.edu>
342 * strports.h, strports.c (scm_eval_0str): Fix constness. Some
343 thanks to Dirk Hermann.
345 * gh_eval.c (gh_eval_str, gh_eval_file, gh_eval_str_with_catch,
346 gh_eval_str_with_standard_handler,
347 gh_eval_str_with_stack_saving_handler): Fix constness. Some
348 thanks to Dirk Hermann.
350 * gh_data.c (gh_str02scm): Fix constness.
352 * gh.h: Fix constness of prototypes for the above.
354 * vectors.c: Include "unif.h" to avoid a warning about missing
355 prototype for scm_uniform_element_size().
357 1999-12-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
359 * vectors.c (scm_vector_length, scm_vector_ref, scm_vector_set_x):
360 Turned into primitive generics.
362 1999-12-04 Gary Houston <ghouston@freewire.co.uk>
364 * ports.c (scm_port_closed_p): new procedure, implements
365 "port-closed?" suggested by Bernard Urban.
366 ports.h: added prototype, removed the SCM_P macros.
368 1999-11-30 Gary Houston <ghouston@freewire.co.uk>
370 * unif.h: added some comments, removed the SCM_P macros.
372 1999-11-29 Gary Houston <ghouston@freewire.co.uk>
374 * vports.c (sf_write): use scm_makfromstr, not scm_makfrom0str
375 (thanks to Daniel Skarda).
377 1999-11-22 Jim Blandy <jimb@savonarola.red-bean.com>
379 * gscm.c, gscm.h: Deleted. They were unused.
381 1999-11-20 Gary Houston <ghouston@freewire.co.uk>
383 * unif.c (scm_list_to_uniform_array): call
384 scm_dimensions_to_uniform_array with a third argument of
385 SCM_UNDEFINED instead of SCM_EOL.
387 1999-11-19 Gary Houston <ghouston@freewire.co.uk>
389 * the following changes allow guile to be built with the array
390 "module" omitted. some of this stuff is just tc7 type support,
391 which wouldn't be needed if uniform array types were converted
394 * tag.c (scm_utag_bvect ... scm_utag_cvect): don't define unless
396 (scm_tag): don't check array types unless HAVE_ARRAYS.
398 * sort.c (scm_restricted_vector_sort_x, scm_sorted_p):
399 remove the unused array types.
400 * (scm_stable_sort, scm_sort): don't support vectors if not
401 HAVE_ARRAYS. a bit excessive.
403 * random.c (vector_scale, vector_sum_squares,
404 scm_random_solid_sphere_x, scm_random_hollow_sphere_x,
405 scm_random_normal_vector_x): don't define unless HAVE_ARRAYS.
407 * gh_data.c (makvect, gh_chars2byvect, gh_shorts2svect,
408 gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect, gh_doubles2dvect,
409 gh_uniform_vector_length, gh_uniform_vector_ref):
410 don't define unless HAVE_ARRAYS.
411 (gh_scm2chars, gh_scm2shorts, gh_scm2longs, gh_scm2floats,
413 don't check vector types if not HAVE_ARRAYS.
415 * eq.c (scm_equal_p), eval.c (SCM_CEVAL), print.c (scm_iprin1),
416 gc.c (scm_gc_mark, scm_gc_sweep), objects.c (scm_class_of):
417 don't support the array types unless HAVE_ARRAYS is defined.
419 * tags.h: make nine tc7 types conditional on HAVE_ARRAYS.
421 * read.c (scm_lreadr): don't check for #* unless HAVE_ARRAYS is
422 defined (this should use read-hash-extend).
424 * ramap.c, unif.c: don't check whether ARRAYS is defined.
426 * vectors.c (scm_vector_set_length_x): moved here from unif.c. call
427 scm_uniform_element_size if HAVE_ARRAYS.
428 vectors.h: prototype too.
430 * unif.c (scm_uniform_element_size): new procedure.
432 * init.c (scm_boot_guile_1): don't call scm_init_ramap or
433 scm_init_unif unless HAVE_ARRAYS is defined.
435 * __scm.h: don't define ARRAYS.
437 * Makefile.am (EXTRA_libguile_la_SOURCES): unif.c and ramap.c
438 moved here from libguile_la_SOURCES.
440 1999-11-18 Gary Houston <ghouston@freewire.co.uk>
442 * socket.c (scm_htons, scm_ntohs, scm_htonl, scm_ntohl): new
443 functions for network data conversion.
445 * numbers.c (scm_num2long, scm_num2longlong):
446 throw out-of-range instead of wrong-type-arg if appropriate.
447 (scm_iint2str): handle -2^31 correctly.
448 (scm_num2long): handle -2^31 bignum correctly.
449 (scm_num2long_long): rewrite the bigdig case: basically copied
451 numbers.h: (SCM_BITSPERLONGLONG): deleted.
453 * unif.c (rapr1): use sprintf instead of intprint for unsigned
454 longs: intprint can't cope with large values.
456 * numbers.c (scm_num2ulong): check more consistently that the
457 input is not negative. if it is, throw out-of-range instead of
460 * ramap.c (scm_array_fill_int): don't limit fill to INUM for
461 uvect, ivect or llvect.
462 Check that fill doesn't overflow short uniform array.
464 * __scm.h: add another long to the definition of long_long and
467 * unif.c (scm_raprin1): use 'l' instead of "long_long" in the
468 print representation of llvect. read can't handle more than
470 (scm_dimensions_to_uniform_array): make "fill" an optional argument
471 instead of a rest argument.
473 * tags.h (scm_tc7_llvect): wasn't defined anywhere, so use the free
476 * __scm.h: don't mention LONGLONGS.
478 * unif.c, numbers.c, eq.c, gc.c, print.c, eval.c, ramap.c:
479 replace LONGLONGS with HAVE_LONG_LONGS as set by configure.
481 1999-11-17 Gary Houston <ghouston@freewire.co.uk>
483 * net_db.c (scm_inet_aton): throw errors using the misc-error key
484 instead of system-error. inet_aton doesn't set errno.
485 system-error isn't right in gethost either, since it's throwing
486 the value of h_errno instead of errno. so:
487 (scm_host_not_found_key, scm_try_again_key,
488 scm_no_recovery_key, scm_no_data_key): new error keys.
489 (scm_resolv_error): new procedure, use the new keys.
490 (scm_gethost): call scm_resolv_error not scm_syserror_msg.
492 1999-11-16 Gary Houston <ghouston@freewire.co.uk>
494 * error.c: (various): use scm_cons instead of scm_listify
495 to build short lists.
497 1999-11-03 Gary Houston <ghouston@freewire.co.uk>
499 * socket.c (scm_fill_sockaddr): zero the address structure before
500 use, in case it has a sin_len field and the OS doesn't like random
501 values (thanks to Bertrand Petit).
503 1999-10-26 Mark Galassi <rosalia@lanl.gov>
505 * gh.h, gh_data.c (gh_symbol2scm): changed gh_symbol2scm() to take
506 a const char * argument, upon suggestion from Lynn Winebarger.
508 1999-10-26 Gary Houston <ghouston@freewire.co.uk>
510 * strports.c (st_end_input): avoid dubious pointer arithmetic.
512 1999-10-24 Gary Houston <ghouston@freewire.co.uk>
514 * Move the responsibility for resetting port buffers from the
515 caller of the ptob seek procedure to the implementation. This
516 gives more control in general to the ptob seek: in particular the
517 change of 1999-10-20 can be made to work without breaking seek on
518 string ports. There's a comment in NEWS about upgrading port
521 * ports.c (scm_seek): don't reset the port buffers here.
523 * fports.c (fport_seek): reset the buffers, except for the
526 * strports.c (st_end_input): (bug fix): decrement pt->read_pos by
527 offset. check that it's not less than read_buf.
528 (st_seek): reset the buffers first, unless it's the 0 SEEK_CUR
529 case and currently reading.
531 1999-10-20 Gary Houston <ghouston@freewire.co.uk>
533 * ports.c (scm_seek): Add a special case for SEEK_CUR, offset 0,
534 so that unread chars are not needlessly discarded. (thanks to
537 1999-10-18 Gary Houston <ghouston@freewire.co.uk>
539 * fports.c (scm_fdes_to_port): always set rw_random if the fdes is
540 random access. rw_active needs to be maintained even for single
541 directional ports, otherwise scm_seek and probably other things are
542 broken. (thanks to Roland Orre).
544 * strports.c (scm_mkstrport): set rw_random to 1 unconditionally.
546 * ports.c (scm_add_to_port_table): initialise rw_random to 0.
548 * ports.h (scm_port): change the comments on rw_random and rw_active.
550 1999-10-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
552 * ioext.c: Added #include "feature.h".
554 These changes turns `delay' into a memoizing macro. This is
555 because it may be expanded before evaluation if it occurs at the
556 beginning of a body. (Thanks to Lauri Alanko.)
558 * eval.c, eval.h (scm_sym_delay): New global symbol.
560 * tags.h (SCM_IM_DELAY): New immediate symbol.
562 * print.c (scm_isymnames): Printed representation.
564 * eval.c (unmemocopy, SCM_CEVAL): Handle SCM_IM_DELAY.
565 (scm_m_delay): Turned into a memoizing macro.

569 1999-10-11 Jim Blandy <jimb@savonarola.red-bean.com>
571 * gh_data.c (gh_ints2scm, gh_doubles2scm): Make sure elements are
572 protected from GC while building the vector. (Thanks to Bernard
573 Urban and Greg Harvey.)
575 1999-10-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
577 * throw.c (handler_message): Display backtrace if backtraces
580 1999-10-05 Jim Blandy <jimb@savonarola.red-bean.com>
582 * Makefile.in, scmconfig.h.in: Deleted from CVS repository. Run
583 the autogen.sh script to create generated files like these.
585 * numbers.c (scm_string_to_number): Signal an error if radix is
586 less than two. (Thanks to Jorgen Schaefer.)
588 * print.c (scm_write, scm_display, scm_newline, scm_write_char):
589 Don't assume that the current output port is valid. Somebody
590 might close it. (Thanks to Bernard Urban.)
592 1999-10-02 Jim Blandy <jimb@zwingli.cygnus.com>
594 * scmconfig.h.in: Regenerated.
596 * Makefile.am (EXTRA_libguile_la_SOURCES): fix typo.
598 Mon Sep 27 17:15:14 1999 Greg J. Badros <gjb@cs.washington.edu>
600 * __scm.h: Fix a bunch of macros that were missing do-while(0)
603 * debug.c, eval.c: Fix buggy uses of SCM_ALLOW_INTS (missing
604 semicolon) exposed by the above change.
606 1999-09-27 Greg J. Badros <gjb@cs.washington.edu>
608 * stacks.c: Avoid compiler warning re: unitialized var.
610 * scmconfig.h.in: Added DEBUG_FREELIST
612 * pairs.h: Fix macro that was not do-while(0) sandwiched.
614 * gc.h, gc.c: Added scm_gc_set_debug_check_freelist_x,
617 1999-09-23 Gary Houston <ghouston@freewire.co.uk>
619 * ioext.c (scm_init_ioext): enable "i/o-extensions" feature here
620 instead of in scm_init_filesys.
622 * init.c (scm_boot_guile_1): don't call scm_init_posix or
623 scm_init_filesys unless HAVE_POSIX is defined.
624 don't call scm_init_netdb or scm_init_socket unless
625 HAVE_NETWORKING is defined.
627 * Makefile.am (EXTRA_libguile_la_SOURCES): filesys.c, posix.c,
628 net_db.c, socket.c: moved here from libguile_la_SOURCES.
630 1999-09-25 Jim Blandy <jimb@savonarola.red-bean.com>
632 * root.c (scm_make_root): Initialize all the fields of the new
633 root. GC could happen any time, you know. (Thanks to Greg
636 * numbers.c (scm_number_to_string): Signal an error if radix is
637 less than two. (Thanks to Jorgen Schaefer.)
639 * Makefile.am (EXTRA_libguile_la_SOURCES): Add memmove.c here,
640 so automake will actually generate rules for it.
641 * Makefile.in: Regenerated.
643 1999-09-21 Jim Blandy <jimb@savonarola.red-bean.com>
645 * backtrace.c: #include "_scm.h" before testing whether
646 HAVE_UNISTD_H is #defined.
648 1999-09-20 Jim Blandy <jimb@savonarola.red-bean.com>
650 * read.c (scm_read): Don't assume that scm_cur_inp is always open.
651 * ports.c (scm_read_char): Same.
652 * ioext.c (scm_read_line): Same.
653 (Thanks to Bernard Urban.)
655 1999-09-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
657 * vectors.c (scm_vector_move_right_x): Bugfix: Remove side effect
659 numbers.c: Removed #ifndef SCM_RECKLESS at places where type
660 checking may invoke a generic. (Thanks to Michael Livshin.)
662 * __scm.h (SCM_WTA_DISPATCH_0, SCM_GASSERT0): New macros.
664 * numbers.c (scm_max, scm_min, scm_sum, scm_difference,
665 scm_product, scm_divide): Bugfix: Don't pass SCM_UNDEFINED to the
666 generic function if the asubr is called with only one arg.
668 1999-09-20 Gary Houston <ghouston@freewire.co.uk>
670 * scmsigs.c (scm_sigaction): add SA_RESTART to flags only if
671 HAVE_RESTARTABLE_SYSCALLS.
672 (scm_init_scmsigs): use siginterrupt if it's available. not
673 everyone who has restartable syscalls has SA_RESTART it seems.
675 (scm_sigaction): use scm_num2long/scm_long2num when converting
676 SIG_DFL/SIG_IGN, in case it doesn't fit in an INUM. use
677 scm_integer_p to test the type.
679 1999-09-18 Gary Houston <ghouston@freewire.co.uk>
681 * _scm.h, scmsigs.c: replace HAVE_RESTARTS with
682 HAVE_RESTARTABLE_SYSCALLS.
684 * strports.c (scm_strport_to_string): create the string from
685 pt->read_buf instead of an expression that evaluates to the
688 * gdbint.c (gdb_print): don't just use SCM_CHARS to get a C string
689 from the port: the port's buffer may not be NUL terminated.
691 1999-09-16 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
693 * Makefile.am (.c.x): Added missing semicolon after `false'.
695 1999-09-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
697 * print.c (scm_iprin1): Turn `write' and `display' into
698 primitive generics and use their associated generic functions in
699 scm_iprin1 for GOOPS objects.
701 * backtrace.c: #include <unistd.h> if present.
703 1999-09-14 Jim Blandy <jimb@savonarola.red-bean.com>
705 * Makefile.am (.c.x): Don't create a subshell just to delete the
706 .x file and return false.
707 * Makefile.in: Regenerated.
709 1999-09-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
711 * feature.c (scm_create_hook): New function. Replaces
712 scm_make_named_hook which is now deprecated.
713 (scm_make_hook_with_name): New primitive.
714 (print_hook): Hooks now print in a fancy way.
716 1999-09-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
718 * __scm.h, backtrace.c, backtrace.h, debug.c, debug.h, dynl-dld.c,
719 dynwind.c, dynwind.h, eval.h, evalext.c, evalext.h, feature.c,
720 feature.h, hashtab.c, hashtab.h, objects.c, objects.h, print.c,
721 procs.c, procs.h, smob.c, smob.h, srcprop.c, strorder.c, struct.c,
722 struct.h: Updated copyright notices.
724 * srcprop.c (scm_source_property): Bugfix: Use SCM_NECONSP instead
725 of SCM_NCONSP. (Thanks to Greg Badros.)
727 * gsubr.c (scm_make_gsubr): Use scm_make_subr_opt for creation of
730 * eval.c, debug.h (SCM_BACKTRACE_WIDTH): New debug option: width.
732 * backtrace.c: Keep backtraces within specified width by
733 adaptively adjusting fancy printing parameters and cut output if
735 (scm_display_application): Check args.
737 1999-09-11 Jim Blandy <jimb@savonarola.red-bean.com>
739 Change the name of the objects returned by OPENDIR from
740 "directory" to "directory stream". A predicate named "directory?"
742 * filesys.c (scm_directory_stream_p): Renamed from scm_directory_p.
743 At the Scheme level, "directory?" -> "directory-stream?".
744 (scm_dir_print): Use the phrase "directory stream" in printed form.
745 * filesys.h (scm_directory_stream_p): Prototype renamed
748 * Makefile.am (CLEANFILES): Remove versiondat.h; that should only
749 be removed by `make distclean', since it's generated by configure.
750 * Makefile.in: Regenerated.
751 (Thanks to Robert Bihlmeyer.)
753 * strop.c (scm_substring_move_x): Signal an error if start1
754 doesn't come before end1. (Thanks to Karoly Lorentey).
756 * numbers.c (scm_istr2flo): Don't call SCM_INEXP without first
757 calling SCM_NIMP. (Thanks to Karoly Lorentey).
759 * version.c (scm_libguile_config_stamp): Deleted. See
760 corresponding change to ../ice-9/boot-9.scm.
761 * versiondat.h.in: Remove definition for GUILE_STAMP.
762 * version.h: Delete prototype.
763 * Makefile.in: Regenerated.
765 1999-09-11 Gary Houston <ghouston@easynet.co.uk>
767 * filesys.c (scm_directory_p): new procedure "directory?" Returns
768 a boolean indicating whether its argument is a directory
769 port as returned by opendir (thanks to Dirk Herrmann for the
772 1999-09-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
774 * backtrace.c (display_frame_expr): Don't print a newline.
775 (display_frame): Print the newline here instead.
776 (display_backtrace_body): Don't print "Backtrace:".
777 (scm_backtrace): Print "Backtrace:" here instead.
779 1999-09-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
781 * procs.c (scm_setter): Signal WTA if handed an entity or operator
784 * feature.c, feature.h: (scm_hook_p, scm_hook_empty_p): New
785 primitives. (Thanks to Greg Badros);
786 (scm_hook_to_list): New primitive; Hooks are now smobs.
788 1999-09-08 Gary Houston <ghouston@easynet.co.uk>
790 * stime.c (bdtime2c): rewrite the ASSERTs. Accept a value
791 of #f for the 10th vector element to avoid an exception
792 seen by Bernard Urban.
793 (scm_mktime): unneeded ASSERT removed.
795 1999-09-07 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
797 * eval.c (scm_map, scm_for_each): Converted to dispatch on generic
800 * __scm.h (SCM_WTA_DISPATCH_n, SCM_GASSERTn): New macros.
802 1999-09-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
804 * numbers.c: Converted comparison operations to dispatch on
805 generic if args don't match.
807 * Makefile.am (ETAGS_ARGS): Added support for GPROC and GPROC1.
809 1999-09-06 James Blandy <jimb@mule.m17n.org>
811 * guile-snarf.c: Deleted. Snarfing should respect CPP
812 conditionals, so it needs to actually run CPP. Bleah.
814 1999-09-05 James Blandy <jimb@mule.m17n.org>
816 Handle errors properly in guile-snarf. (Thanks to Han-Wen Nienhuys.)
817 * guile-snarf.in: Be sure to exit with an error if CPP does.
818 * Makefile.am (.c.x): Delete the .x file and exit with an error
819 status if guile-snarf exits with an error status.
820 * Makefile.in: Regenerated.
822 * snarf.h (SCM_GLOBAL_KEYWORD): Call scm_c_make_keyword, not
823 scm_makekey, which doesn't exist any more. Guess nobody's using
826 * guile-snarf.c: New implementation of guile-snarf, meant to be
827 more robust than the shell script. I think it's complete, but I
828 haven't tested it at all, and I haven't changed the build process
829 to actually use it. We should compare its output against that of
830 the existing shell script, for all source files.
832 * guile-snarf.c (parse_args): Abort if we haven't handled some
835 1999-09-03 James Blandy <jimb@mule.m17n.org>
837 * load.c (scm_search_path): If the filename has any extension at
838 all, ignore the entire list of extensions. Also, don't check whether
839 the file is accessible. If the file exists, accessible or not, we
840 should return it. Inaccessible files should cause an error later.
841 (Thanks to Keisuke Nishida for the suggestions.)
843 1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
845 * gc.c (cleanup, scm_init_storage): Use on_exit if present and
846 atexit not available. (sunos4.1.4 needs it.)
848 1999-09-01 James Blandy <jimb@mule.m17n.org>
850 I take it all back --- bcopy does handle overlapping source and
851 destination areas correctly. At least on every system I could
852 find. But it is better to use AC_REPLACE_FUNCS than to introduce
853 new CPP conditionals.
854 * memmove.c: New file, implementing memmove in terms of bcopy.
855 * scmconfig.h.in: Regenerated.
857 Allocators should use the `void *' type for generic pointers.
858 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
859 argument and return types.
860 * gc.h: Corresponding changes to prototypes.
863 1999-08-31 James Blandy <jimb@mule.m17n.org>
865 * numbers.c (scm_init_numbers): Claim to support the `complex'
866 feature, as expected by (ice-9 format). (Thanks to Ceri Storey.)
868 * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
869 find (ice-9 boot-9) when Guile was compiled in a separate
870 directory from the source. (Thanks to Rodney Brown.)
871 * Makefile.in: Regenerated.
873 * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply
874 table lengths by the size of a single element when growing the
875 table. (Thanks to Bill Schottstaedt.)
877 1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
879 * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
880 SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
881 since that cuts down the time for type dispatch by 50%.
883 1999-08-30 James Blandy <jimb@mule.m17n.org>
885 * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
886 not a correct substitute for memmove, because it doesn't handle
887 overlapping source and destination areas on many platforms.
888 Overlaps are the primary reason to use memmove in the first place.
889 * ports.c (scm_ungetc): Same.
890 * strop.c (scm_substring_move_x): Same.
892 1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
894 * gc.c (scm_init_storage): Skip registration of cleanup on systems
895 which lack atexit. (Is it important that cleanup is made
896 properly? Maybe we should replace all `exit' with `scm_exit' and
899 * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
900 scm_struct_free_standard, scm_struct_free_entity): Declared to
901 return scm_sizet instead of size_t.
903 * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined
904 there on sunos4.1.4.)
906 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
908 * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
909 Account for the case when second argument is unbound.
911 * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
912 (Thanks to Karoly Lorentey.)
914 * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
915 isn't present. (Thanks to Suzuki Toshiya.)
917 * ports.c: Use ANSI C prototypes in definitions. (Thanks to
920 * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
923 * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
924 Bernard Urban and Ian Grant.)
926 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
927 again. (1.3.4 will be binary incompatible with 1.3.2 because of a
928 change in the representation of entities and operators.)
930 1999-08-29 Gary Houston <ghouston@easynet.co.uk>
932 * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
933 don't allocate zero bytes (thanks to Bill Schottstaedt).
935 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
937 * procs.c (scm_setter): Converted to use generic dispatch.
939 * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
942 * load.c (scm_search_path): Don't try extensions which already are
943 present at the end of the filename.
944 (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
946 * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
948 Cleanup and simplification of generic method dispatch.
949 Also, the quadruple representation of entity and operator
950 procedures has been replaced with single.
952 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
954 * print.c (scm_isymnames): Removed #@hash-dispatch.
956 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
957 from eval.c; Support 0 arity methods.
958 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
959 (scm_apply_generic_env): Removed.
960 Replaced slots proc0-3 with procedure.
962 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
963 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
964 SCM_OPERATOR_PROCEDURE.
965 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
966 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
968 * struct.c, struct.h: Replace 4 procedure slots with one.
969 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
971 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
974 * eval.c (scm_sym_args): Removed.
975 (SCM_CEVAL): Simplified entity application.
976 Moved dispatch code to objects.c.
978 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
980 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
982 * sort.c (closureless): Use scm_eval_body.
984 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
985 with a symbol as last form was first called normally and then via
986 `map' or some other mechanism using primitive apply, an ILOC was
989 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
991 This change extends the representation of primitive procedures
992 with more data fields, e.g. a place for documentation and true
993 procedure properties.
995 * procs.c, procs.h (scm_subr_entry): New type: Stores data
996 associated with subrs.
997 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
998 SCM_SUBR_DOC): New macros.
999 (scm_subr_table): New variable.
1000 (scm_mark_subr_table): New function.
1002 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
1004 * gc.c (scm_gc_mark): Don't mark subr names here.
1005 (scm_igc): Call scm_mark_subr_table.
1008 This change implements a scheme for letting a generic work as a
1009 shadow for a primitive procedure. If the primitive procedure
1010 can't dispatch on its arguments, control is left over to the
1011 generic. Normal wrong type arg errors will be generated until the
1012 user has hung the first method on the primitive.
1014 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
1016 * procs.c, procs.h (scm_subr_p): New function (used internally).
1018 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
1020 * objects.c, objects.h (scm_primitive_generic): New class.
1022 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
1024 * print.c (scm_iprin1): Print primitive-generics.
1026 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
1027 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
1029 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
1030 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
1031 primitives). NOTE: This means that it is now *required* to use
1032 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
1033 obscured representation that will be removed in the future anyway,
1034 so backward compatibility is no problem here).
1036 * numbers.c: Converted most numeric primitives (all but bit
1037 comparison operations and bit operations) to dispatch on generic
1038 if args don't match.
1041 Better support for applying generic functions.
1043 * eval.c, eval.h (scm_eval_body): New function.
1045 * objects.c (scm_call_generic_0, scm_call_generic_1,
1046 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
1050 Optimization of the generic function dispatch mechanism.
1052 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
1053 called scm_memoize_method instead of doing a second lookup.
1055 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
1060 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
1061 scm_sysintern so that the binding connected with the subr name
1062 isn't cleared when we give set = 0.
1065 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1067 More transparent handling of ports with print states.
1069 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
1070 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
1071 instead of a pair of a port and a print state. We'll need to cons
1072 once extra in scm_printer_apply but the type system will be
1073 cleaner, it will mix better with GOOPS, and, it will be even more
1074 transparent to the user.
1076 * print.c (scm_get_print_state): New procedure: Given an output
1077 port, return the print state associated to it in the current print
1078 chain, if one exists;
1079 (scm_port_with_print_state): New procedure: Associate a
1080 print-state with a port.
1081 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
1082 (scm_printer_apply): Wrap port and pstate as a smob;
1083 (print_state_printer): Removed.
1085 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
1087 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
1090 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
1091 testing (otherwise the port-print-state trick won't be transparent
1092 to the user; one example where this caused problems was in the
1093 (ice-9 format) module).
1095 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1097 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
1098 SCM_UNSPECIFIED instead of the set value.
1100 1999-08-20 James Blandy <jimb@mule.m17n.org>
1102 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
1104 * ports.h (enum scm_port_rw_active): New enum, containing
1105 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
1106 zero). The debugger knows about enums, but doesn't know about
1108 (typedef scm_port): Declare rw_active member to be an enum
1110 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
1112 * ports.c (scm_add_to_port_table): Same.
1113 * strports.c (st_flush, st_end_input): Same.
1115 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
1116 scm_must_realloc, and scm_done_malloc as appropriate.
1118 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1120 * sort.c (quicksort): Added condition to protect the algorithm
1121 from crashing the interpreter if the less predicate is buggy.
1123 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
1125 * fports.c (fport_write): fix line-buffering mode again.
1126 (scm_open_file): recognise 'l' for line-buffering.
1127 (scm_setvbuf): recognise _IOLBF for line-buffering.
1129 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1131 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
1134 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
1135 evaluating closures.
1137 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
1139 * fports.c (fport_write): use memcpy instead of strncpy, in case
1140 the data contains NUL.
1142 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1144 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
1146 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
1147 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
1148 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
1149 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
1150 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
1151 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
1152 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
1153 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
1154 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
1155 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
1156 scm_sym_ as prefix for symbols.
1158 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
1160 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
1161 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
1162 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
1163 scm_sym_atcall_cc): Made global.
1165 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1167 * eval.c (scm_sym_args): Made global.
1169 * objects.c (scm_set_object_procedure_x): Disallow setting of
1170 procedures for pure generic functions.
1172 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
1174 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
1175 Scheme name from lseek to seek, but lseek was added recently so
1176 it shouldn't be a big problem.
1177 * ports.c, gdbint.c, ioext.c: changed callers.
1179 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
1181 * fports.c (fport_input_waiting): if select is used, return 1
1182 instead of whatever FD_ISSET expands to. maybe it will be useful
1183 to interpret the value from the input_waiting ptob procedure as a
1184 lower bound on the number of bytes available.
1186 * Mikael asked for a few names to be changed...
1188 * ports.c (scm_make_port_type): take the write procedure as the
1189 second argument instead of the flush procedure.
1190 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
1191 fflush -> flush, read_flush -> end_input, fclose -> close,
1192 fill_buffer -> fill_input, ftruncate -> truncate,
1193 input_waiting_p -> input_waiting.
1195 * ports.c (end_input_void_port): was read_flush_void_port.
1196 (scm_set_port_end_input): was scm_set_port_flush_input.
1197 (scm_set_port_flush): was scm_set_port_write.
1198 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
1199 (scm_end_input): was scm_read_flush.
1200 (scm_fill_input): was scm_fill_buffer.
1201 (scm_flush): was scm_fflush.
1202 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
1203 (fport_end_input): was local_read_flush.
1204 (fport_flush): was local_fflush.
1205 (fport_close): was local_fclose.
1206 (fport_truncate): was local_ftruncate.
1207 (fport_seek): was local_seek.
1208 (fport_free): was local_free.
1209 (fport_fill_input): was fport_fill_buffer.
1210 * strports.c (st_end_input): was st_read_flush.
1211 (st_truncate): was st_ftruncate.
1212 * vports.c: (sf_flush): was sfflush.
1213 (sf_close): was sfclose.
1214 (sf_fill_input): was sf_fill_buffer.
1216 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
1219 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1221 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
1222 forms now contain the expressions to be dispatched upon instead of
1223 depending on a surrounding lambda or let; Generic function
1224 dispatch has been optimized; `apply' on a generic function now
1225 works a little bit strangely. It uses a trick so that the type
1226 dispatch code in SCM_CEVAL can be reused.
1228 * objects.h, objects.c (scm_apply_generic_env): Added (used by
1230 (scm_operator_p): Added.
1231 (scm_sym_atdispatch): Added.
1232 (scm_set_object_procedure_x): Modified to handle the new style
1234 (scm_object_procedures): New debugging procedure.
1236 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1238 * eval.c, eval.h (scm_sym_args): Added.
1240 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
1242 * feature.c, feature.h (scm_c_run_hook): Added.
1244 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
1245 cdrxnoap and loopnoap instead of begin and loop.
1247 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
1249 * ports.c (scm_putc, scm_puts),
1250 * unif.c (scm_uniform_array_write): use scm_lfwrite.
1251 * ports.c (scm_putc): change type of first argument from int to char.
1253 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1255 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
1256 SCM_IM_HASH_DISPATCH.
1258 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
1259 (scm_si_redfined, scm_si_hashsets): Moved.
1261 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
1262 flag which combines type and status info so that the class
1263 redefinition protocol has zero cost during normal execution.
1265 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
1267 * ports.h (scm_ptob_descriptor): include a write procedure again.
1268 it's more efficient for unbuffered fports (e.g., sockets.)
1270 * ports.c (scm_puts): use ptob->write.
1271 * vports.c (scm_make_sfptob): set write proc in ptob.
1272 * strports.c (scm_make_stptob): set write proc in ptob.
1273 * ports.c (write_void_port): new procedure.
1274 * vports.c (sf_write): new procedure.
1275 * ports.c (scm_lfwrite): use ptob->write.
1276 * strports.c (st_write): new procedure.
1277 * fports.c (fport_write): new procedure.
1278 (scm_make_fptob): set write in ptob to fport_write.
1279 * ports.h: prototype for scm_set_port_write.
1280 * ports.c (scm_make_port_type): initialise ptob write procedure.
1281 (scm_set_port_write): new proc.
1283 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
1285 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
1286 until we've verified that it is actually a port. (Thanks to
1289 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1291 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
1292 code, particularly an unnecessary test (len != size, where len ==
1293 size). (Was this leftovers from debugging code, or have I missed
1294 something profound?)
1296 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
1297 size. (Thanks to James Dean Palmer.)
1299 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
1300 (Thanks to Lorentey Karoly.)
1302 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1304 * eval.c (scm_m_expand_body): Use scm_cons_source.
1306 * struct.c (scm_print_struct): Use vtable name.
1308 * print.c (scm_init_print): Set name of print state type.
1310 * stacks.c (scm_init_stacks): Set name of stack type.
1312 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1314 * eval.c (SCM_CEVAL): Removed old implementation of internal
1317 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
1319 * debug.c, debug.h (scm_reverse_lookup): Added.
1320 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
1321 internal procedure definitions; Don't use scm_i_inner_name.
1323 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
1324 New isym operations.
1326 * eval.h: Added prototypes for multi language support functions.
1328 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
1329 improper lists in the low-level representation, since that will
1330 cause a begin to be prepended at macro expansion.
1332 * eval.c (scm_cons_source): Version of cons which copies source
1333 properties from an existing cell.
1334 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
1336 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
1337 procedure source before calling scm_unmemocopy instead of faking
1340 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1342 Ported `internal defines' fix from SCM. Original ChangeLog entry:
1344 1998-07-09 Radey Shouman <radey@colorage.com>
1346 * eval.c (ceval_1): Modifications to allow rewriting of interal
1347 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
1348 body of which it is the CAR is macro expanded by m_expand_body,
1349 which rewrites internal DEFINE.
1351 (m_expand_body): Added.
1353 (m_macroexp1): Added argument to control error checking:
1354 m_expand_body may speculatively expand forms in the wrong
1355 environments. Made argument number checks conditional on
1358 (m_body): Added, error checks bodies and inserts the ISYM tokens.
1360 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
1363 (m_cond): (m_case): (m_quote): Modified to avoid destructively
1364 changing their argument forms. Since m_expand_body
1365 speculatively macro expands forms the process must be
1368 (m_ident_eqp): Fixed to use proper environment.
1370 (renamed_ident): Added DEFER_INTS_EGC.
1372 Added prototypes for static functions.
1378 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
1379 is false, do not produce an error for unbound variables, return a
1380 pointer to cell_undef instead.
1382 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
1386 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
1387 destructively changing their argument forms. Since m_expand_body
1388 speculatively macro expands forms the process must be reversible.
1390 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
1391 SCM_IM_LET introduced by named lets.
1393 (scm_m_letstar): Use scm_m_body instead of bodycheck.
1395 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
1396 scm_letrec. scm_letrec1 does not check for a null binding and
1397 takes an additional argument to specify the ISYM of the body. Use
1398 scm_m_body instead of bodycheck.
1400 (scm_m_let): Use scm_m_body instead of bodycheck.
1402 (scm_m_expand_body, scm_macroexp): New.
1404 (unmemocopy): Account for ISYMs introduced by scm_m_body.
1406 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
1407 check=1. Throw error for internal defined that have not been
1408 rewritten by scm_m_expand_body.
1410 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
1411 Removed prototype for SCM_APPLY.
1413 * tags.h: Added extern declaration of scm_isymnames.
1415 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1417 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
1419 * lang.c: New file: Beginning of multi-language support.
1421 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
1423 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
1424 (scm_dynamic_wind): Added argument checking for the after guard so
1425 that we don't add garbage on the dynwind chain.
1426 (scm_swap_bindings): Added.
1428 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
1429 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
1430 (scm_isymnames): New isyms for multi-language support.
1432 * eval.c (scm_nil, scm_t): New symbols.
1433 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
1434 forms for multi-language support.
1436 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1438 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
1440 Renamed functions in the random function library interface
1441 from scm_i_XXX --> scm_c_XXX.
1443 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
1445 * ports.c (scm_putc): fix line-buffering.
1447 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1449 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
1450 scm_set_ptob_XXX --> scm_set_port_XXX.
1452 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1454 * ports.c, ports.h (scm_make_port_type): New interface for
1455 creation of port types (replaces scm_newptob). Just as for the
1456 smobs, we need to separate the internal representation of smob
1457 types from the interface, so that we easily can add new fields and
1458 rearrange things without caring about backward compatibility.
1459 This change was forced by the need in GOOPS to create classes
1460 representing port types.
1461 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
1462 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
1463 scm_set_ptob_seek, scm_set_ptob_truncate,
1464 scm_set_ptob_input_waiting_p): New setters.
1465 (scm_newptob): Rewritten to use scm_make_port_type. For backward
1467 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
1468 (scm_prinport): Removed.
1469 (scm_port_print): Added.
1470 (scm_print_port_mode): Added.
1471 (void_port_ptob, print_void_port, close_void_port, noop0):
1472 Removed. Removed #include "genio.h" Added #include "objects.h",
1475 * fports.c (prinfport): Moved code from ports.c.
1476 (local_free): Added.
1477 (scm_fptob): Removed. Instead use new interface.
1478 (scm_make_fptob): Added. (Need to create basic ports in a
1479 specific order in ports.c.)
1481 * strports.c (scm_stptob, prinstpt, noop0): Removed
1482 (scm_make_stptob): Added.
1484 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
1485 (scm_make_sfport): Added.
1487 * filesys.c (scm_dir_print): Don't use the port printing code.
1488 Instead provide specific directory printer.
1490 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
1492 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
1493 scm_ptob_descriptor.
1495 * smob.c (scm_smob_print): Handle non-existing type name nicely.
1496 Removed #include "genio.h"
1498 * objects.c (scm_make_port_classes): New function ptr.
1500 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
1502 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
1504 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
1505 allow the 1st argument to be a fdes or filename as well as a
1506 port (as in the filesys.c version).
1508 * filesys.c (scm_truncate_file): removed.
1510 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1512 * readline.c, readline.h: Removed.
1514 * objects.c, objects.h (scm_port_class): Added.
1515 (scm_class_of): Look up port class in scm_port_class.
1516 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
1517 SCM_INOUT_PCLASS_INDEX): Added.
1520 * Makefile.am: Removed genio.c, genio.x.
1524 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1526 * init.c: Make sure that scm_post_boot_init_modules is called only
1527 once. (Important when using a dumped image.; Thanks to Bernard
1530 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
1532 * guardians.c (scm_guardian_zombify): Separate scanning for
1533 zombies from marking the pairs of the free list.
1535 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
1536 use the macros. (Thanks to Michael Livshin.)
1538 * eval.c (scm_m_lambda): Let bodycheck check the body of the
1539 lambda. Let your sins be purified by the blood of the lambda.
1540 (Thanks to Eric Hanchrow.)
1542 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
1543 (Thanks to Valdis Kletnieks.)
1545 Fixes for EMX from Mikael Ståldal.
1547 * filesys.c: #include <io.h>, if we have it.
1548 * scmconfig.h.in: Regenerated.
1550 * stime.c (ftime): Delete declaration for this function --- let
1551 the system supply it.
1553 Cleanups from John Bley.
1555 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
1557 * gsubr.c: Don't include "gsubr.h" twice.
1559 Cleanups for compilation on Irix 6, from David Kaelbling.
1561 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
1562 regex_t pointer. This is what the callers have, mostly.
1563 (scm_regexp_exec): Don't forget to pass the `rx' argument to
1564 scm_regexp_error_msg.
1566 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
1567 int. That way, if we get a warning on this line, it's more likely
1568 that we're really missing bits we care about.
1570 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
1573 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
1574 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
1575 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
1576 cast at all is more appropriate in every case. At the moment, we
1577 assume everywhere that SCM is an integral type anyway.
1579 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
1581 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
1582 read_pos after scm_fill_buffer.
1584 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
1587 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
1588 fports.c (fport_fill_buffer): implement the interface change.
1590 * ports.c (scm_fill_buffer): interface change: no longer increments
1591 read_pos past the character that's returned. it seems clearer to
1592 leave it to the caller to decide what to do (thanks Jim).
1594 * vports.c (sf_fill_buffer): put the read char into the buffer
1595 as well as returning it.
1597 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure
1600 1999-07-13 Gary Houston <ghouston@easynet.co.uk>
1602 * strports.c (scm_strprint_obj): simplify. start with initial
1604 (st_seek): don't allow string to be extended if seeking past
1605 the end of a read-only port.
1607 1999-07-12 Gary Houston <ghouston@easynet.co.uk>
1609 * strports.c (st_seek): change the resize checks.
1611 * ports.c (scm_ftruncate): throw error if offset works out negative.
1613 * strports.c (st_flush): increase string size in blocks of
1614 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
1615 it's greater and reset read_buf_size.
1616 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
1617 to be maintained for output ports too (it holds the written
1618 part of the string, while write_buf may have unwritten buffer
1620 (st_truncate): rewritten.
1621 (top of file): added a few notes.
1623 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
1625 Patch from Greg Badros:
1626 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
1627 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
1628 (function pointer) argument to scm_make_gsubr and scm_make_subr
1629 calls. This avoids warnings in C++ programs using guile-snarf.
1631 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
1633 * strports.c (st_grow_port): set pt->read_pos. set
1634 pt->read_buf_size one less than pt->write_buf_size if there's
1635 an unwritten char at the end of the string. similarly for
1637 (st_resize_port): renamed from st_grow_port.
1638 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
1639 seek from read_end instead of write_end for SEEK_END.
1640 (st_ftruncate): calculate current length using readbuf, not write
1642 (scm_strport_to_string): use read_buf_size for length.
1643 (stfill_buffer): don't re-initialise the readbuf.
1645 1999-07-05 Gary Houston <ghouston@easynet.co.uk>
1647 * strports.c (scm_strport_to_string): new procedure.
1648 (scm_call_with_output_string, scm_strprint_obj): use

1652 1999-07-08 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1654 * symbols.c (scm_gensym): Bugfix. (Thanks to Johannes Hjorth.)

1658 * smob.c: added scm_make_smob_type_mfpe (), scm_set_smob_mfpe ();
1659 use scm_make_smob_type_mfpe to initialize "free", "flo", "bigpos",
1660 and "bigneg" smob types.
1662 * smob.h: Add do ... while(0) idiom to SCM_NEWSMOB. Added
1663 SCM_RETURN_NEWSMOB macro. Added protos for new functions in
1666 * *.c: Use scm_make_smob_type_mfpe, instead of scm_newsmob, and
1667 use SCM_NEWSMOB or SCM_RETURN_NEWSMOB in constructors instead of
1668 SCM_NEWCELL and setting the CAR/CDR by hand.

1752 trinary conditional in order for the flag computation to be
1755 1999-06-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1757 * struct.c, struct.h:
1759 In order to support different kinds of deallocation, a destructor
1760 slot has been added to struct vtables. This allows for structs
1761 containing pointers to other memory blocks.
1763 (scm_struct_i_free): New hidden struct slot. Holds destructor for

1832 1999-06-19 Jim Blandy <jimb@savonarola.red-bean.com>
1834 Patch from Greg Harvey:
1835 * eq.c, eval.c, list.c, ramap.c, vectors.c: Always write parens
1836 around the condition of an `if', `while', etc., even if the
1837 condition is a macro invocation that expands to something
1838 surrounded by parens. It's more readable.
1840 * eval.c (scm_map, scm_for_each): Verify that all arguments are
1841 proper lists, and of the appropriate lengths.
1842 (check_map_args): New function. (Thanks to Greg Harvey for the
1845 1999-06-19 Michael Livshin <mike@olan.com>

1864 (scm_igc): Check for underflow by seeing if this is negative.
1866 * gc.h (scm_mallocated): Fix declaration.
1867 (Thanks to Greg Harvey.)
1869 * ports.h: #include <sys/types.h>, to get a definition for `off_t'.

1879 * weaks.h (SCM_WVECT_GC_CHAIN): New macro to access it.
1880 * gc.c (scm_weak_vectors): Now a SCM instead of a SCM*, and now
1882 (scm_weak_size, scm_n_weak): Deleted.
1883 (scm_igc): Use SCM_WVECT_GC_CHAIN to build up a chain of weak
1884 vectors without allocating new storage during GC, using
1885 scm_weak_vectors as the head of the chain.
1886 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
1887 instead of stepping through an array.
1888 (scm_gc_sweep): Update offset used to find start of weak vector to
1890 (scm_init_storage): Set scm_weak_vectors to EOL.
1892 Fix from Ken Raeburn <raeburn@raeburn.org>:
1893 * gc.c (already_in_gc): New variable.
1894 (scm_igc): Set and clear already_in_gc; abort if it's set at
1897 1999-06-14 Jim Blandy <jimb@savonarola.red-bean.com>
1899 Fix from Gary Houston:
1900 * fports.c (local_seek): Signal an error if the seek fails.
1901 * ports.c (scm_lseek): Don't check return value of port's seek
1902 function; it's its job to signal an error if there's a problem.
1904 1999-06-12 Jim Blandy <jimb@savonarola.red-bean.com>
1906 * strports.c (scm_call_with_output_string): Don't include the

1911 * fports.c, fports.h, gc.c, gdbint.c, ioext.c, ports.c, ports.h,
1912 scmsigs.c, strports.c, vports.c: Install the sources which
1913 actually correspond to the changes described below. I got the
1914 ChangeLog entries and the patch from two different places...
1916 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
1918 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
1919 it shows up as terrible performance, as we GC constantly.
1921 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
1922 newline. A bit faster, and definitely hairier.
1923 (scm_read_line): Count newlines here instead.
1925 * strings.c (scm_take_str): New function.
1926 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h
1927 (scm_take_str): New declaration. * ioext.c (scm_read_line): Use
1928 scm_take_str, to avoid copying the string.
1930 Add some simple-minded support for line buffered ports.
1931 * ports.h (SCM_BUFLINE): New flag for ports.
1932 * init.c (scm_init_standard_ports): Request line-buffering on
1933 the standard output port.
1934 * ports.c (scm_mode_bits): Recognize 'l' as a request for line
1936 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
1937 and there's a newline to be written, flush the port.
1939 Gary Houston's open-buffer port patches:
1941 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
1943 * ports.c: (scm_lseek): clear buffers even if just reading current

1954 strports.c (scm_mkstrport): check that pos is reasonable.
1955 ioext.c (scm_ftell, scm_fseek): use lseek.
1956 (SCM_CLEAR_BUFFERS): macro deleted.

1959 ports.c (scm_newptob): set ftruncate.
1961 ports.c (scm_ftruncate): new procedure.
1962 fports.c (local_ftrunate), strports.c (str_ftruncate): new procs.

1964 fports.h (scm_port): change size types from int to off_t.
1965 ports.c (scm_init_ports): initialise the seek symbols here
1966 instead of in ioext.c.
1967 strports.c (scm_call_with_output_string): start with an empty
1968 string, so seek and ftruncate can be used.
1970 gdbint.c: adjust string port usage.
1972 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
1974 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
1975 equivalent to fflush for the read buffer.
1976 * ports.c (scm_newptob): set read_flush.
1977 ports.c (void_port_ptob): set read_flush.
1978 fports.c (local_read_flush): new proc. add to ptob.
1979 strport.c (st_read_flush): likewise.
1980 vport.c (sf_read_flush): likewise.
1981 fports.h (struct scm_fport): remove random member. there's nothing
1982 left but fdes. leaving it as a struct to allow for future changes.
1983 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
1984 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
1985 ptob proc if the read buffer is filled.
1987 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
1989 * ports.h (scm_port): add a rw_random member and replace
1990 reading and writing members with rw_active member.
1991 SCM_PORT_READ/SCM_PORT_WRITE: new values.
1993 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
1995 * ports.h (struct scm_port_table): add writing and reading members
1996 to replace write_needs_seek: it isn't good enough for non-fports.
1997 ports.c, ioext.c, fports.c: corresponding changes.
1998 (struct scm_port_table): give it a typedef and rename to scm_port.
1999 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
2000 corresponding changes.
2002 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
2004 * ports.c (scm_newptob): bugfix: set seek member.
2005 * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
2006 and generalised to all port types.
2008 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
2010 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
2011 signals (it was only being done for handlers installed from Scheme).
2012 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
2013 waiting for input caused an EINTR error from read.
2015 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
2017 * ports.h (struct scm_port_table): make all the char members
2018 unsigned, so they convert to int without becoming negative if large.
2020 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
2022 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
2023 with threads enabled. rename this procedure to
2024 fport_wait_for_input and take a port instead of a fdes.
2025 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
2027 * readline.c (scm_readline): Applied a patch from Greg Harvey to
2028 get readline support working again: use fdopen to get FILE objects.
2030 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
2032 * gc.c (scm_init_storage): install an atexit proc to flush the
2034 (cleanup): the new proc. it sets a global variable which can be
2035 checked by the ptob flush procs to avoid trying to throw
2036 exceptions during exit. not very pleasant but it seems more reliable.
2037 * fports.c (local_fflush): check terminating variable and if set
2038 don't throw exception.
2039 * CHECKME: that the atexit proc is installed if unexec used.
2041 * throw.c (scm_handle_by_message): don't flush all ports here.
2042 it still causes bus errors.
2044 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
2045 and move to ioext.c.
2047 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
2049 * ports.c (scm_char_ready_p): check the port buffer and call the
2050 ptob entry if needed.
2052 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
2053 ptob initialisers. use it in char-ready
2055 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
2057 * vports.c (sfflush): modified to write a char (since softports
2058 currently use shortbuf.)
2060 * fports.c (scm_standard_stream_to_port): moved to init.c and
2063 * init.c (scm_init_standard_ports): make stdout and stderr
2064 unbuffered if connected to a terminal. with stdio they
2065 were line-buffered by default.
2067 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
2070 * ports.h (scm_ptobfuns): change fflush return to void.
2071 change flush proc definitions.
2073 * strports.c (scm_call_with_output_string): get size from
2074 buffer instead of port stream.
2075 (st_flush): new proc.
2077 * ports.h (struct scm_port_table): added write_end member,
2078 as an optimisation. set it where write_buf_size is set.
2080 * ports.h (struct scm_port_table): change stream from void *
2081 back to SCM. SCM presumably must be large enough to hold a
2082 pointer (and probably vice versa but who knows.)
2083 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
2085 (scm_puts): rewritten
2086 * fports.c (local_ffwrite, local_fputs): removed.
2087 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)
2088 * vports.c (sfputc, sfputs, sfwrite) likewise.
2089 * ports.c (write_void_port, puts_void_port): removed.

2455 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2457 Most of this batch of changes is about how to deal with extended
2458 types when an object system is loaded into Guile. A nice object
2459 system is capable of representing Guile's types as class objects.
2461 For example, we want a regular expression to be of class <regex>.
2462 But regular expressions are smobs which aren't under direct
2463 control of the object system, so there has to be some mechanism
2464 which informs the object system that a new class should be created
2465 which can represent the smob type. I call this a "wrapper class".
2467 * objects.c: #include "smob.h";
2468 (scm_class_keyword): Removed. (Class is automatically created by
2470 (scm_smob_class): Array of smob classes indexed by smobnum.
2471 (scm_make_extended_class): "Plugin" function pointer for creation
2472 of wrapper classes for smob and struct types.
2473 (scm_class_of): Handle compiled closures. (Currently regarded as
2475 Use scm_smob_class to handle smob types;
2476 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
2477 through scm_smob_class;
2480 * smob.c (scm_newsmob): Also create a wrapper class if
2481 scm_smob_class has been initialized.
2483 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
2484 type code and smobnum.
2486 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
2487 (scm_struct_table): Weak key table with auxilliary information for
2488 struct types. Currently used for names and wrapper classes.
2489 (scm_struct_ihashq): Hash function for structs.
2490 (scm_struct_create_handle): Get/create entry in scm_struct_table.
2491 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
2492 for accessing names of vtables. The record implementation in
2493 boot-9.scm currently uses the setter to record the name of record
2494 types. When the object system is initialized, it can use this
2495 information to create wrapper classes with suitable names.
2496 (scm_init_struct): Allocate scm_struct_table.
2497 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
2498 (struct tags are a finite resource and we might want to restrict
2499 the use of tags to vtables only. E.g., Goops only uses tags for
2501 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
2503 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
2506 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
2507 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
2508 Used for access of struct table entries.
2510 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
2511 (scm_hash_fold): New procedure. Used to process all entries in a
2512 hash table (in no particular order).
2514 Argh! For the umpteenth time I got compilation errors because of
2515 the "intuitive" name `kw'. This has to have an end:
2517 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
2518 "kw" --> "keywords" everywhere.
2519 (I doubt that this will cause big compatibility problems since the
2520 application interface is unaffected.)
2522 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
2524 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2526 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
2527 column inums to native form.
2529 Improvement of backtraces: Introduces a new stack narrowing
2530 specifier, #t, for the inner cut. (See further in the comments in

2534 (Used to flag certain system procedures which shouldn't turn up in
2537 * eval.c (scm_sym_system_module): New symbol. (Used to flag
2538 modules which aren't "user" modules and the code of which

2542 Extract the lookup closure from an environment.
2543 (scm_system_module_env_p): New function: Return non-#f if MODULE

2549 * debug.c (scm_procedure_name): Use name property in the default
2552 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
2554 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
2556 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
2557 procedure throughout.
2559 * print.c (scm_iprin1): Removed extraneous space when printing
2560 procedure-with-setters.
2562 Entity and operator setter slots were introduced as a complement
2563 to the <procedure-with-setter> type in order to support entities
2564 and operators with setters in a reasonable and efficient way.
2565 * procs.c (scm_procedure, scm_setter): Handle entity and operator
2568 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.

2580 * objects.h (SCM_OBJ_CLASS_REDEF): New macro: Find class slots
2581 directly through the instance.
2583 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
2585 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
2586 scm_struct_i_flags instead of scm_vtable_index_layout!
2588 * list.c (scm_list_star): New procedure.
2590 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2592 * debug.c (scm_init_debug): Added scheme level constant

2609 Readline paren matching from Greg Harvey, with modifications from
2612 * readline.c (in_readline, reentry_barrier_mutex): Make these
2615 * readline.c: #include <sys/time.h> and "iselect.h", so we can
2616 control how long we're paused, and threads will run while we're
2618 (match_paren, find_matching_paren, init_bouncing_parens): New
2620 (scm_init_readline): Call init_bouncing_parens.

2671 SYMB now point to const.
2673 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2675 * print.c (scm_iprin1): Use scm_procedure_name instead of
2676 scm_procedure_property for compiled closures.
2678 * tags.h (scm_tc7_pws): New procedure type. Four representations
2679 for procedure-with-setters were considered before selecting this
2682 1. A closure where the CODE and ENV slots are used to represent
2683 the getter and a new SETTER slot is used for the setter. The
2684 original getter is stored as a `getter' procedure property. For
2685 closure getters, the CODE and ENV slots contains a copy of the
2686 getter's CODE and ENV slots. For subr getters, the CODE contains
2689 2. A compiled closure with a call to the getter in the cclo
2690 procedure. The getter and setter are stored in slots 1 and 2.
2692 3. An entity (i.e. a struct with an associated procedure) with a
2693 call to the getter in the entity procedure and the setter stored
2694 in slot 0. The original getter is stored in slot 1.
2696 4. A new primitive procedure type supported in the evaluator. The
2697 getter and setter are stored in a GETTER and SETTER slot. A call
2698 to this procedure type results in a retrieval of the getter and a
2699 jump back to the correct eval dispatcher.
2701 Representation 4 was selected because of efficiency and
2704 Rep 1 has the advantage that there is zero penalty for closure
2705 getters, but primitive getters will get considerable overhead
2706 because the procedure-with-getter will be a closure which calls
2709 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
2710 <procedure-with-setter>, but together with rep 2 it suffers from a
2711 three level dispatch for non-GOOPS getters:
2713 cclo/struct --> dispatch proc --> getter
2715 This is because the dispatch procedure must take an extra initial
2716 argument (cclo for rep 2, struct for rep 3).
2718 Rep 4 has the single disadvantage that it uses up one tc7 type
2719 code, but the plan for uniform vectors will very likely free tc7
2720 codes, so this is probably no big problem. Also note that the
2721 GETTER and SETTER slots can live directly on the heap, using the
2722 new four-word cells.
2724 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,
2725 SCM_SETTER): New macros.

2797 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
2799 * alloca.c (alloca): Cast value returned by malloc. (Thanks to

2804 * random.c: Removed alloca includes.
2806 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
2808 * Makefile.in: This changed, for some reason I don't really
2809 understand, when I ran automake in the top level directory. This
2810 may be contamination by Cygnus internal releases. If you re-run
2811 automake and this change gets reverted, don't worry about it.

2840 * guardians.c, guardians.h (scm_make_guardian,
2841 scm_guardian_gc_init, scm_guardian_zombify, scm_guard,
2842 scm_get_one_zombie, scm_init_guardian): This is an implementation
2843 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
2844 David Eby (1993) "Guardians in a Generation-Based Garbage
2845 Collector" ACM SIGPLAN Conference on Programming Language Design
2846 and Implementation, June 1993 ftp://ftp.cs.indiana.edu

2857 1998-12-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2859 * macros.c (scm_makacro, scm_makmacro, scm_makmmacro): Added
2862 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2864 Move the procedure slots of entities to invisible slots (so that
2865 we can have operator class objects which themselves are entities).
2866 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
2867 SCM_STRUCTF_ENTITY): New constants.
2869 * struct.c (scm_make_struct): Allocate "invisible" room for
2870 procedures if SCM_STRUCTF_ENTITY is set in vtable.

2880 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
2882 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
2884 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
2885 of syntactic forms, similar to SCM_PROC.
2886 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
2887 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
2888 for the name symbols when needed.
2890 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
2892 * Makefile.in: Regenerated.
2894 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
2896 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
2897 take the address of _into; it might be a register. Just have
2898 scm_debug_newcell return the new cell.
2899 * gc.c (scm_debug_newcell): Just return the new cell, instead of
2900 taking the address of a place to store it as an argument.
2901 * gc.h (scm_debug_newcell): Change declaration.
2902 (Thanks to Greg Harvey.)
2904 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

2917 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2919 * backtrace.c (display_frame): Made more robust. Doesn't throw an
2920 error if no source properties can be found for a frame. (Thanks
2921 to Christian Lynbech.)
2923 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2925 * objects.h: Removed slots direct_supers and direct_slots from the
2926 definitions of the rudimentary classes described by objects.h.
2928 * objects.c, objects.h (scm_entity_p): New procedure. Together
2929 with the predicates scm_procedure_p and scm_struct_p, this
2930 predicate makes it possible to differ between structs, entities
2933 * modules.c, modules.h (scm_resolve_module): New function.
2935 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2937 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
2938 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
2941 * objects.c (scm_entity_p): New procedure.

2948 * procprop.h (scm_i_procedure_arity): Added declaration.
2950 * procprop.c (scm_i_procedure_arity): Made global; New code to
2951 handle operators and entities.
2952 (scm_procedure_property): No need to call scm_procedure_p since
2953 scm_i_procedure_arity now does all necessary type checking.
2954 Added #include "objects.h".
2956 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
2957 s_add_hook_x --> s_remove_hook_x.
2958 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.

2962 (scm_make_hook): Optional argument defines number of arguments to
2964 (scm_make_named_hook): Take number of args as second arg.
2965 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
2966 boot-9.scm for a while); First arg is the hook. The rest are
2967 arguments passed on to the hook procedures.
2969 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
2971 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
2972 scm_logbit_p): Do the computation in ulongs. This is not as nice
2973 as doing it in bignums, but at least it's good enough for
2974 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
2976 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
2977 subexpressions. (Thanks to Charbel Jacquin.)
2979 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
2981 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
2982 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
2983 (scm_make_named_hook): New function.
2985 * feature.c: Added #include "eval.h".
2987 * modules.c (scm_make_module): Beautify the module.
2989 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2991 * modules.c, modules.h: New files: C interface to modules. (This
2992 is necessary in order to interface the object system to Guile
2993 properly. The guts of these modules will be replaced by the new
2994 module system in the future.)
2996 * init.c: Added #include "modules.h"
2997 (scm_boot_guile_1): Call scm_init_modules.
2998 (invoke_main_func): Call scm_post_boot_init_modules.
3000 * Makefile.am: Added modules.c, modules.x, modules.h.
3002 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
3004 * procs.c: #include "objects.h"
3005 (scm_procedure_p): Return #t also on structs which are operators.
3007 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
3008 <operator-metaclass> and <entity-class> to <standard-class>,
3009 <operator-class> and <entity> in order to conform with STKlos
3012 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
3013 which isn't an operator.
3014 (SCM_APPLY): Ditto, but jump to badproc.
3016 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
3018 * eval.c (SCM_CEVAL): Allow structs implanted in code.
3019 Previously, structs implanted in code were interpreted as forms
3020 the operator of which was a gloc. We solve this by checking for
3021 the zero in the emulated vcell in the struct vtable. Since
3022 implanted structs always will look like forms with a gloc
3023 operator, execution will only be slowed down by maximally one
3024 extra test-and-branch per application.
3026 * evalext.c (scm_definedp): Removed check for isyms; Added a
3027 second optional argument: It is now possible to supply an
3028 evaluation environment in which to look for the symbol.
3030 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3032 * readline.c (scm_init_readline): Set
3033 rl_basic_word_break_characters. (Thanks to Ian Grant.)
3035 * coop.c (coop_condition_variable_wait): Removed
3036 (coop_condition_variable_wait_mutex): Folded logic of
3037 coop_mutex_unlock into coop_condition_variable_wait_mutex to
3038 prevent condvar signal lossage. Previously, another thread could
3039 start to run after unlocking the mutex but before putting the
3040 current thread on the wait queue. If that thread then would
3041 signal the first, the signal would be lost. (Thanks to Christian
3044 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3046 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
3049 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3051 * objects.c (scm_i_make_class_object): Renamed from
3052 make_class_object; exported; error checking moved to
3053 scm_make_class_object and scm_make_subclass_object.
3054 (scm_make_class_object, scm_make_subclass_object): Use
3055 scm_i_make_class_object.
3056 (scm_make_subclass_object): Let the subclass have same metaclass
3059 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3061 * debug.c (scm_debug_options): Bugfix: Set the value of
3062 scm_stack_checking_enabled_p after setting debug options;
3063 #include "stackchk.h". (Thanks to Richard Polton.)
3065 1998-11-13 Radey Shouman <rshouman@metro2000.com>
3067 * unif.c (scm_array_contents): removed unnecessary test for 0
3070 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3072 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
3073 Replaced by macro `collect' in boot-9.scm.
3075 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3077 * eval.c (scm_copy_tree): Copy source properties if existent.
3079 * debug.c (scm_start_stack): Copy source when evaluating. (If we
3080 don't, we may end up passing memoized source to a transformer.)
3082 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3084 * stack.c (get_applybody): Help function which lookups the first
3085 body form of the apply closure.
3086 (read_frames): Prevent the source of the first form of the apply
3087 closure from being recorded. This would only be confusing.
3089 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
3090 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
3092 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
3094 * stacks.c (read_frame): Bugfix: Removed lingering `else'
3096 (read_frames): Use SCM_MACROEXPP.
3098 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3100 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
3101 don't contain interesting information since all arguments are
3102 present in the frame which applies the compiled closure anyway.);
3103 Skip the transformer application frames.
3105 * print.c (scm_iprin1): Print gsubrs as primitives.
3107 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3109 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
3111 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
3112 that we can identify these in a backtrace. (This change doesn't
3113 introduce any significant speed penalty.)
3115 * eval.c: Added note about `serial-map' using scm_map.
3117 * read.c, read.h (scm_read_options, scm_read_opts): Removed
3118 readline options. They should reside in their own options array.
3120 * readline.c, readline.h (scm_readline_options,
3121 scm_readline_opts): Moved readline options here.
3123 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3125 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
3126 SCM_ROCHARS instead of SCM_CHARS.
3128 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
3129 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
3131 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3133 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
3134 This is quite important since the latter clears the
3135 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
3136 every single character read...
3138 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3140 * print.c (scm_iprin1): Removed suspect looking (and indeed
3141 malevolent) semicolon after test for user supplied closure print
3142 procedure. (Thanks to Telford Tendys.)
3144 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
3145 (scm_memq, scm_memv, scm_member): Do argument checking *before*
3146 starting to search the list. Removed call to sloppy_mem_check.
3148 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
3149 procedures: Same as scm_delq_x et al, but delete maximally one
3152 * options.c (scm_options, scm_init_options): GC-protect option
3153 values of type SCM. (Thanks to Telford Tendys.)
3155 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3157 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
3158 make sure that there always is a "real" scm_lookupcar.
3160 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3162 * read.c, read.h (scm_read_opts): New read options
3163 "history-length" and "history-file".
3164 (scm_read_options): Stifle history to history length.
3166 * readline.c (scm_read_history, scm_write_history): New procedures.
3168 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3170 * eval.h (scm_macro_eval_x): Removed declaration.
3172 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
3173 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
3174 Renamed and made global.
3176 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
3177 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
3179 * evalext.c, evalext.h: New files. Contain non-R5RS things
3180 having to do with evaluation.
3182 * evalext.c (scm_serial_map): New procedure: Version of `map'
3183 which guarantees that the procedure is applied to the lists in
3185 (scm_m_sequence_to_list): New syntax: Version of `begin' which
3186 returns a list of the results of the body forms instead of the
3187 result of the last body form.
3188 (scm_definedp, scm_m_undefine): Moved from eval.c
3190 * evalext.h (scm_m_sequence_to_list): Added declaration.
3192 * macros.c, macros.h: New files.
3193 (scm_procedure_to_syntax, scm_procedure_to_macro,
3194 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
3195 scm_macro_name, scm_macro_transformer): Moved from eval.c
3196 (scm_make_synt): Moved from eval.c
3198 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
3200 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
3203 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
3205 * debug.c, print.c: Added #include "macros.h".
3207 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3209 This change adds the ability to use `unread-char' multiple times
3210 without interspersed reads and adds the new procedure
3211 `unread-string'. The change is optimized for the common case of
3212 unreading a single character. This is also the reason behind the
3213 choice to store characters in the port itself: in most cases no
3214 extra malloc is required.
3216 The amount of code in some macros in ports.h has been increased to
3217 the extent that they would fit better as C functions, but, since
3218 this code belongs to the port representation, such functions
3219 should be placed in ports.c which would cause calls back and forth
3220 between ports.c and genio.c. That is not good for performance.
3221 Also, keeping them as macros allows the compiler to do some
3222 optimizations which are needed to make the current interface
3223 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
3225 One benchmark (Guile startup time) indicates an increase of
3226 loading speed of 1%. Another (reading (using `read') boot-9.scm
3227 10 times) shows no change in performance.
3229 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
3230 made to find a beautiful solution.)
3232 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
3233 (SCM_TRY_CLRDY): New macro: Only clear the first unread
3234 character. (SCM_CLRDY clears all.)
3235 (SCM_N_READY_CHARS): New macro: Returns number of unread
3236 characters in a port. Returns wrong answer if SCM_CRDYP is false.
3237 (struct scm_port_table): New fields: `entry' contains port table
3238 index, `cp' points to last unread char, `cbuf' is the buffer for
3239 unread chars, `cbufend' points after end of the character buffer.
3241 * ports.h, ports.c (scm_unread_string): New procedure.
3242 (scm_grow_port_cbuf): New function.
3244 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
3246 (scm_generic_fgets), fports.c (local_fgets): Use a loop
3247 to read unread characters. Use SCM_TRY_CLRDY instead of
3250 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
3252 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
3254 * genio.c, genio.h (scm_ungets): New function.
3256 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
3259 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3261 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
3262 declarations. (Thanks to Russ McManus.)
3264 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3266 * numbers.c (num2long): As a software archeologist, I'm proud of
3267 this finding! :) Preliminary dating suggests an almost 4 year old
3268 remnant from the SCM ancestor. The sample has been removed from
3269 the finding site and is now safely stored in the repository.
3271 * numbers.h: Removed prototype for num2long.
3273 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
3275 * gh_data.c (gh_scm2doubles): Make it possible to pass result
3276 array as second arg.
3277 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
3278 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
3279 * gh.h: Updated and added prototypes.
3281 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
3283 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
3285 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
3287 * guile-snarf.in: Never generate an empty file. (Thanks to
3290 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
3291 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
3292 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
3293 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
3294 gh_new_procedure5_0): Specify argument types, to appease C++
3295 compilers. (Thanks to Brad Bowman.)
3297 Bug reports from Russ McManus:
3298 * guile-snarf.in: If the CPP environment variable is set, use that
3299 as the C preprocessor, instead of the preprocessor autoconf
3301 * snarf.h (SCM_PROC): Cast the function pointer passed to
3302 scm_make_gsubr, to satisfy C++.
3304 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
3305 Use the handler passed, instead of ignoring it and using
3306 gh_standard_handler. (Thanks to Etienne Bernard.)
3308 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
3310 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
3313 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>

3330 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
3333 * script.c (scm_compile_shell_switches): Define
3334 use-emacs-interface in the root module, so the repl code can see
3335 it. See today's change to top-repl in ice-9/boot-9.scm.
3337 * filesys.c (set_element, get_element): Make sure that `element'
3338 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
3339 Boekemeier and Jorgen "forcer" Schaefer.)
3341 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
3343 * chars.c (scm_charnames): In ASCII character name table, make
3344 newlines print as #\newline by default, not #\nl.
3346 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
3347 alphabetical order. Oh thrills. But it helps me know how far
3348 along in the compilation I am.
3349 * Makefile.in: Regenerated.
3351 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3353 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
3354 #bytes(...) to #y(...), and syntax for short vectors from
3355 #short(...) to #h(...). This may seem nutty, but, like the other
3356 uniform vectors, byte vectors and short vectors want to have the
3357 same print and read syntax (and, more basic, want to have read
3358 syntax!). Changing the read syntax to use multiple characters
3359 after the hash sign breaks with the conventions used in R5RS and
3360 the conventions used for the other uniform vectors. It also
3361 introduces complexity in the current reader, both on the C and
3362 Scheme levels. (The Right solution is probably to change the
3363 syntax and prototypes for uniform vectors entirely.)
3365 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
3367 Don't use local_fgets on sockets; ftell doesn't work on sockets.
3368 (Thanks to Jorgen "forcer" Schaefer.)
3369 * ports.h (SCM_NOFTELL): New flag.
3370 * fports.c (local_fgets): If it's set, use the generic fgets.
3371 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
3373 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3375 * script.c (scm_compile_shell_switches): Add handling of -q switch
3376 (inhibit loading of user init file).
3377 (scm_shell_usage): Add usage text for -q switch.
3378 (scm_compile_shell_switches): Always load user init file first if
3379 it is loaded at all.
3381 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
3383 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
3384 and is now broken under NetBSD. I can't fathom what it's trying
3385 to do, so I've replaced it with something that I do understand,
3386 which seems to work, and which isn't broken on NetBSD. "Progress?
3387 You Decide." (Thanks to Perry Metzger.)
3389 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
3390 signed/unsigned comparison.
3392 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
3394 Warning fixes from Greg Harvey:
3395 * unif.c (scm_array_set_x): initializer for pos
3396 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
3397 * struct.c (scm_struct_ref, scm_struct_set_x): Added
3398 initializers for field_type, since EGCS so desparately wants to
3400 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
3401 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
3402 when GUILE_DEBUG is defined.
3403 * dynwind.h (scm_wind_chain): Same.
3404 * ports.h (scm_pt_size, scm_pt_member): Same.
3405 * print.h (scm_current_pstate): Same.
3406 * procs.h (scm_make_cclo): Same.
3408 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
3410 Handle short and long long uniform arrays properly. (Thanks to
3412 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
3413 raeql_1): Add cases for scm_tc7_svect (short vectors) and
3414 scm_tc7_llvect (long long vectors).
3416 Change the way libguile and boot-9.scm are timestamped, to try to
3417 get rid of these spurious mismatch warnings. Now both
3418 libguile/versiondat.h and ice-9/version.scm are generated directly
3419 by the configuration process, rather than having version.scm
3420 generated directly, and libguile/versiondat.h generated by the
3421 Makefile, which is generated by configure. It seems that
3422 sometimes the Makefile would change, but versiondat.h depends on
3423 Makefile.in, not Makefile, so it wouldn't get rebuilt.
3424 * Makefile.am (versiondat.h): Target removed; this is generated
3425 directly by the configure script now.
3426 (BUILT_SOURCES): Remove versiondat.h.
3427 * versiondat.h.in: New file, transformed by the configure script
3429 * Makefile.in: Regenerated.
3431 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
3432 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
3433 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
3434 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
3435 if we want to use them in a header file some day, we can. (Thanks
3436 to Michael Livshin.)
3438 * stime.c (scm_get_internal_real_time): Do the arithmetic using
3439 SCM numbers, so we won't have rollover problems; the range of a
3440 signed long in milliseconds is about 25 days. (Thanks to Karl
3443 Don't redefine sleep and usleep; fix this problem now.
3444 * coop.c (sleep, usleep): Remove declarations; we don't use or
3445 redefine these any more.
3446 (scm_thread_usleep, scm_thread_sleep): New functions which do the
3447 job of usleep and sleep in a thread-friendly way. We can use
3448 these in the rest of Guile. Define versions for systems both with
3449 and without iselect.
3450 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
3451 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
3452 we're just using it, not redefining it, we can use a K&R style
3454 (sleep): Declare this, too, if the system hasn't.
3455 (scm_sleep, scm_usleep): Use scm_thread_sleep and
3456 scm_uthread_sleep if they're available; otherwise, just call the
3458 * scmconfig.h.in: Regenerated.
3460 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
3462 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
3464 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
3466 * threads.c: Doc fix.
3468 The argument type of usleep varies from system to system,
3469 as does the return type. We really shouldn't be redefining usleep
3470 at all, but I don't have time to clean that up before the 1.3.
3471 release. It's on the schedule for afterwards. (Thanks to Julian
3473 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
3475 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
3476 * scmconfig.h: Regenerated.
3478 * simpos.c (scm_software_type): Procedure deleted. This isn't the
3479 right way to handle system variation. Autoconf's approach is the
3481 * simpos.h (scm_software_type): Declaration deleted.
3483 * script.c (scm_find_executable): Don't test if unix is #defined
3484 here; first, NetBSD doesn't #define it, and second, it's the wrong
3485 way to go about these things. (Thanks to Perry Metzger.)
3486 (dld_find_executable): Delete this MSDOS support code. This isn't
3487 the way we want to support this; it needs to be rethunk at a
3490 * genio.c (scm_do_read_line): Don't just politely check that the
3491 line was either non-empty or EOF. Abort if it's empty and not
3494 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
3496 * scmconfig.h.in: Regenerated.
3498 * libguile.h: Don't omit the dynamic linking functions. (Thanks
3501 * genio.c (scm_do_read_line): Count lines correctly when the file
3502 doesn't end in a newline.
3504 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
3506 * genio.c (scm_do_read_line): Maintain the line count correctly.
3507 (Thanks to Harvey J. Stein and Greg Harvey.)
3509 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
3512 * numbers.c (big2str): Protect t from garbage collection until
3513 we're done. (Thanks to Gary Houston.)
3515 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
3517 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
3519 * Makefile.in: Regenerated.
3521 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
3522 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
3525 Do magic to mix reads and writes on stdio FILE-based ports.
3526 (Thanks to Christian Lynbech.)
3527 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
3529 (pre_read, pre_write): New functions.
3530 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
3531 local_fputs): Call them.
3532 (local_fflush): Mark the port as ready for reading and writing.
3533 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
3534 flags on new port objects. This might not be accurate --- who
3535 knows what state the FILE * is in when we get it --- but it won't
3536 do extraneous calls to fflush or fseek, so it's no worse than the
3537 behavior before this change.
3538 * ports.h: Add comment.
3540 Centralize the creation of port objects based on stdio FILE * in
3541 fports.c; don't just throw them together anywhere.
3542 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
3543 what the rest of Guile wants. Don't set the revealed count;
3544 that's only appropriate for stdin, stdout, stderr.
3545 (scm_standard_stream_to_port): This function does set the revealed
3547 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
3548 not scm_stdio_to_port.
3549 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
3550 * fports.c (scm_open_file): Same.
3551 * posix.c (scm_pipe): Same.
3552 * socket.c (scm_sock_fd_to_port): Same.
3553 * ioext.c (scm_fdopen): Same.
3554 (scm_freopen): Moved from here to...
3555 * fports.c (scm_freopen): ... here. This is really something that
3556 munges the internals of an fport, so it should go here.
3557 * fports.h (scm_stdio_to_port): Adjust prototype.
3558 (scm_standard_stream_to_port, scm_freopen): New protoypes.
3559 * ioext.h (scm_freopen): Prototype removed.
3561 * filesys.c (set_element, get_element): This can work on both pipe
3562 and file ports, so use SCM_FPORTP to typecheck, instead of testing
3565 * scmconfig.h.in: Regenerated.
3567 Change the definition of the functions in scm_ptobfuns so that
3568 they get passed the port object, not the port's stream.
3569 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
3570 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
3571 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
3572 Pass the port itself to the scm_ptobs function.
3573 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
3574 scm_generic_fgets): Same.
3575 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
3576 getc_void_port, fgets_void_port, close_void_port): Just change the
3577 argument names; these functions don't really do anything.
3578 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
3579 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
3580 port as an argument, and use SCM_STREAM to get the stdio FILE *.
3581 Also, use prototyped definitions, and get rid of the extra
3583 (scm_fptob, scm_pipob): We don't need casts here any more.
3584 * strports.c (prinstpt): Use prototype declarations.
3585 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
3586 and use SCM_STREAM to get the string info. Also, use prototyped
3587 definitions, and get rid of the extra declarations.
3588 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
3591 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
3592 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
3594 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
3595 scm_fgets, for consistency.
3596 (scm_fptop, scm_pipob): References updated.
3598 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
3600 Include the source location in error messages for scripts.
3601 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
3602 stack is still there when we catch the error.
3603 * throw.c (handler_message): If we are handling an error with a
3604 message, then put together the proper arguments and call
3605 scm_display_error, instead of scm_display_error_message. That
3606 displays source location, if it can find it.
3608 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
3610 * gc.c (scm_unprotect_object): Change this so that calls to
3611 scm_protect_object and scm_unprotect_object nest properly.
3612 (scm_protect_object): Doc fixes.
3614 * strings.c (scm_string_set_x): Require the argument to be a
3615 writable string, not a substring or a symbol.
3616 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
3617 (Thanks to John Redford and Charbel Jacquin.)
3619 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
3621 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
3623 * eval.c (safe_setjmp): Remove this misunderstanding.
3624 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
3627 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
3629 * libguile.h: Mark these as C declarations, for compilation by C++
3632 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
3633 __cplusplus clause. I seriously doubt this ever worked the way
3634 the author seems to have intended.
3636 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
3638 Utterly needless cleanups to hopelessly messy code.
3639 * ports.c: Doc fixes.
3640 (scm_fflush): Moved to ...
3641 * genio.c (scm_fflush): ... here, amongst all the other port
3642 method invocation functions.
3643 * genio.h, ports.h: The prototype moves too.
3645 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
3647 * backtrace.c (display_error_body): The current frame does not
3648 always have a parent frame; consider a function called directly
3649 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
3652 * alloca.c (alloca): Undo yesterday's changes, and simply call
3653 malloc directly for storage, and abort if we don't get what we
3654 want. The situation is much simpler --- just call malloc. Emacs
3655 has bizarre/evil requirements (signal handlers might malloc unless
3656 you set this global flag, so you have to set the flag around all
3657 calls to malloc) which we are certainly not going to conform to,
3658 so we can do the simple and obvious thing.
3660 * coop.c (coop_condition_variable_wait): Make this function
3661 static. It's only useful internally --- you should never just
3662 wait on a condition variable.
3663 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
3665 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3667 * unif.c (scm_array_set_x): Accept any kind of number as an
3668 element for a uniform vector of doubles. This is more consistent
3669 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
3671 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
3672 works; I can't conveniently test it myself. (Thanks to Dvid
3673 Tillman for the bug report.)
3675 * init.c: Doc fixes.
3677 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
3678 from here, not from scm_compile_shell_switches (which is a pretty
3679 dumb place to do it).
3680 (scm_load_startup_files): New function.
3681 (scm_ice_9_already_loaded): Variable moved to here from script.c.
3682 * script.c (scm_compile_shell_switches): Don't load the startup
3684 (scm_ice_9_already_loaded): Variable moved.
3685 * init.c (scm_load_startup_files): Prototype for new function.
3686 * gh_init.c (gh_enter): Doc fix.
3688 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3690 Some anti-warning changes from Greg Harvey.
3691 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
3692 warnings when it doesn't understand our NORETURN declarations in
3694 * posix.c (scm_mknod): Similar.
3696 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3698 * posix.c (scm_getpwuid): If we can't find an entry, return our
3699 own message, instead of using scm_syserror --- the getpwMUMBLE
3700 functions don't set `errno' to anything interesting.
3702 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3704 Get rid of warnings from the cooperative threading system.
3705 * threads.h (scm_single_thread_p, scm_yield,
3706 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
3707 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
3708 scm_wait_condition_variable, scm_signal_condition_variable): Add
3709 prototypes for these Scheme-visible functions.
3710 * coop-defs.h (coop_next_runnable_thread,
3711 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
3712 Prototypes for these here, even though they're from iselect.c.
3713 (coop_condition_variable_wait, coop_join): Add prototypes.
3714 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
3715 scm_threads_free_condvar): Make these smob functions static.
3716 * coop-threads.h (coop_init): Give this a real prototype.
3717 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
3718 (coop_next_runnable_thread): No need to provide prototype; it's in
3721 * scmconfig.h.in: .detarenegeR
3723 * iselect.c, threads.c: Doc fixes.
3725 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3727 * Makefile.in: Regenerated with a patched automake, to get
3728 dependency generation right when using EGCS.
3730 * inet_aton.c (inet_aton): Add prototype, to remove compiler
3731 warning. (Thanks to Robert Pluim.)
3733 * inet_aton.c (inet_aton): Reassure the compiler that the
3734 arguments to the <ctype.h> macros are all unsigned characters, not
3737 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3739 Getting rid of more warnings...
3740 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
3741 today's change to ../configure.in.
3742 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
3743 * scmconfig.h.in: Regenertaded.de.,.__
3744 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
3745 (scm_localtime, scm_mktime): Use a const char * to manipulate the
3748 * readline.c: Doc fix.
3749 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
3750 * readline.h (scm_filename_completion_function): Add prototype.
3751 (scm_init_readline): Make this into a prototype.
3753 * readline.c (scm_filename_completion_function): Use SCM_PROC to
3754 declare this, instead of calling scm_make_subr manually.
3756 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
3758 * readline.h (scm_init_readline): Add prototype for this.
3759 (scm_init_readline): Make this a real prototype.
3761 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
3763 Warning fixes from Maciej Stachowiak:
3764 * backtrace.h (scm_display_application, scm_backtrace): Add
3766 * debug.c (scm_m_start_stack): Make this function static.
3767 * fluids.h (scm_fluid_p): Add prototype.
3768 * procprop.c (scm_i_procedure_arity): Make this function static.
3769 * regex-posix.c (scm_regexp_error_msg): Make this function static.
3770 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
3771 * root.h (scm_dynamic_root): Add external prototype.
3772 * scmsigs.h (scm_usleep): Add external prototype.
3773 * script.h (scm_init_script): Use prototype, not K&R decl.
3774 * stacks.h (scm_stack_id): Add external prototype.
3775 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
3777 1998-09-30 Mark Galassi <rosalia@cygnus.com>
3779 * gh.h: took out the definitions of vset and vref, since they are
3780 replaced by the proper vector routines that correspond to the R4RS
3783 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
3785 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
3786 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
3787 third argument, a C expression that should result in a SCM value,
3788 which is used to initialize the variable. Reimplemented
3789 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
3792 * version.h (scm_libguile_config_stamp): Add prototype.
3793 (From Maciej Stachowiak.)
3795 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
3797 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
3798 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
3800 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
3802 * print.c (scm_iprin1): Rather than having one i, and using it in
3803 several places, declare a fresh i local to each block where it is
3804 used, and give it a signedness appropriate to its use in each case.
3805 (scm_iprlist): Same.
3807 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
3808 comparison warnings.
3810 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
3811 signed/unsigned clashes.
3813 * posix.h (scm_tmpnam): Added prototype.
3815 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
3816 scm_make_subclass_object): Add external prototypes.
3818 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
3819 comparison is okay here.
3821 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
3823 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
3824 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
3826 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
3829 * load.c (swap_port): Make this function static.
3831 * load.c (scm_search_path): Make max_path_len and max_ext_len
3832 unsigned, since they're compared against string sizes.
3834 * load.c (init_build_info): Make i unsigned.
3836 * ioext.h (scm_read_line): Add prototype.
3838 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
3839 scm_hash_fn_remove_x): Make hash bucket index local variable k
3840 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
3841 accurately as possible.
3843 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
3844 comparisons, and range checking to make sure those casts are
3847 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
3848 signed/unsigned comparisons.
3850 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
3851 avoid signed/unsigned comparisons.
3852 * smob.h (scm_numsmob): Change extern declaration to match.
3854 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
3855 avoid signed/unsigned comparisons.
3856 * ports.h (scm_numptob): Change extern declaration to match.
3857 (scm_current_load_port, scm_set_port_line_x,
3858 scm_set_port_column_x): New prototypes.
3860 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
3861 test code, and it causes warnings.
3863 * gh.h (gh_int2scmb, gh_uniform_vector_length,
3864 gh_uniform_vector_ref): Added prototypes.
3866 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
3867 debugging support unconditionally. That's backtrace.c, stack.c,
3868 debug.c, and srcprop.c.
3869 (EXTRA_libguile_la_SOURCES): Omit those from here.
3870 * Makefile.in: Regenerated.
3872 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3874 * options.c (scm_options): Bugfix: Allow empty list of options!
3876 * debug.c, debug.h (scm_single_step): Removed.
3877 (scm_with_traps): New procedure. This procedure could easily be
3878 written in Scheme but needs to be highly optimized.
3880 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
3882 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
3883 Check SCM_TRAPS_P before trapping.
3885 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
3887 Changes to avoid signed/unsigned comparison warnings.
3888 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
3889 (scm_gc_sweep): Make n and j local to the blocks they're used in,
3890 so they can have appropriate types for each application. Make i
3891 signed. Use initializers in some spots. I'll probably pay for
3893 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
3894 (scm_must_realloc): Make nm unsigned.
3895 (init_heap_seg): Make new_seg_index and n_new_objects signed.
3896 (scm_init_storage): Use prototype-style definition, and make the
3898 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
3899 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
3901 * filesys.c (scm_readlink): Make local vars rv and size ints, to
3902 avoid signed/unsigned comparison warnings, and because the return
3903 value of readlink may be -1. Don't bother casting the third
3904 argument to readlink.
3906 * filesys.c (scm_dirname, scm_basename): Move these to their own
3907 page, at the end of the file.
3908 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
3910 * eval.h (scm_eval_options_interface): Add external prototype for this.
3911 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
3913 * eval.c (scm_lookupcar1): Make this static.
3915 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
3916 Make these prototype declarations, not K&R-style.
3918 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
3919 unsigned comparison warning.
3921 * appinit.c: File removed. It had a single function in it, empty,
3922 whose reason for existence is explained in no documentation or
3923 comment. I think it's there as a default for some Tcl-style
3924 initialization, but Tcl abandoned that approach a while ago.
3925 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
3926 (BUILT_SOURCES): Remove appinit.x.
3927 * Makefile.in: Regenerated.
3929 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3931 * Makefile.in: Regenerated using the last public version of
3932 automake, not the hacked Cygnus version.
3934 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
3936 Remove Totoro kludge.
3937 * Makefile.in, scmconfig.h.in: Regenerated.
3938 * init.c, readline.c: Don't check if TOTORO is #defined.
3940 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
3942 * Makefile.am: Adjust for new thread configuration system.
3943 (INCLUDES): Include the value of THREAD_CPPFLAGS.
3944 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3946 (THREAD_LIBS): Definition deleted; automake will generate such
3947 things automatically.
3948 * Makefile.in: Regenerated.
3950 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3952 Simplify smob and port marking; set the mark bit in the generic
3953 marking code, and make marker routines only responsible for
3954 turning up outgoing pointers.
3955 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3956 before calling the marking function. Don't call the marking
3957 function if it's zero.
3958 * markers.c (scm_mark0): Just return #f. This function isn't
3959 necessary at all now, but it's harmless to call it. We'll leave
3960 it in so other folks' code doesn't croak at link time.
3961 (scm_markcdr): Don't call SCM_SETGC8MARK.
3962 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3963 * dynl.c (mark_dynl_obj): Same.
3964 * root.c (mark_root): Same.
3965 * srcprop.c (marksrcprops): Same.
3966 * unif.c (markra): Same.
3967 * variable.c (scm_markvar): Same.
3968 * ports.c (scm_markstream): Same.
3969 (void_port_ptob): Specify zero for our marking function.
3970 * debug.c (debugobjsmob): Same.
3971 * dynwind.c (guardsmob): Same.
3972 * filesys.c (dir_smob): Same.
3973 * fluids.c (fluid_smob): Same.
3974 * fports.c (scm_fptob, scm_pipob): Same.
3975 * mallocs.c (mallocsmob): Same.
3976 * regex-posix.c (regex_t_smob): Same.
3977 * smob.c (freecell, flob, bigob): Same.
3978 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
3979 * throw.c (jbsmob, lazy_catch_funs): Same.
3981 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3983 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
3984 scm_copy_tree on code in order not to let memoized code to leak
3985 out. Thus, scm_copy_tree needs to copy vectors as well since
3986 quasiquote can introduce evaluated code also inside vector
3989 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3991 * eval.c (scm_copy_tree): Removed ability to copy vectors.
3993 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
3994 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
3997 * unif.c: Say that ivect and uvect are of type signed and unsigned
3998 long instead of int in commentary so that it correctly describes
4001 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
4003 * stime.c: Removed declaration of strptime. (It should be
4004 declared by the system headers. If it turns out that some systems
4005 don't, we'll handle that then.) (Thanks to Greg Troxel.)
4007 * stime.h: Renamed TIMEH --> STIMEH
4009 * backtrace.c (scm_display_error, scm_display_backtrace): In order
4010 to increase portability, don't use structure assignment.
4011 (Thanks to Nicolas Neuss.)
4013 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
4015 (finalize_fd_sets): Added empty statement after last case label.
4016 (Thanks to Nicolas Neuss.)
4018 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
4021 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
4023 * init.c, readline.c: OK, I won't have these readline.x bug
4024 reports anymore. We've had them since April. The current reason
4025 is a completely unintelligible failure of totoro.red-bean.com to
4026 do the test for rl_getc_function in libreadline correctly. This
4027 kludge overrides the test if we're on totoro so that the snapshot
4028 generation process can work.
4030 * readline.c: Define a strdup replacement if not existent on system.
4032 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
4034 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
4035 This change makes scm_make_vector R5RS compatible. We cannot keep
4036 the third argument since people want to be able to deduce the form
4037 of the C function call only by looking at R5RS. (At the same time
4038 we have removed some unnecessary complexity!)
4040 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
4041 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
4042 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
4043 argument in call to scm_make_vector.
4045 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4047 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
4048 This macro is useful in applications.
4050 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
4052 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
4053 (scm_parse_path, scm_search_path): New Scheme level procedures.
4055 * load.h (scm_internal_parse_path, scm_parse_path,
4056 scm_search_path): Declared.
4058 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4060 * filesys.c (dirname, basename): New procedures.
4062 * init.c (scm_boot_guile_1): Removed condition around
4065 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
4066 new data type (guards) for representation of C level guards and
4067 data on the wind chain.
4068 (scm_internal_dynamic_wind): New function.
4070 * dynwind.h: Declare scm_internal_dynamic_wind.

4080 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
4082 * ports.c (current-load-port): New procedure.
4084 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4086 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
4087 not a tty, return #f.
4089 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
4090 to Julian Satchell and Roland Kaufmann.)
4092 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
4093 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
4095 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
4097 * debug.h, debug.c (scm_start_stack): New function. Implements
4098 the guts of old scm_m_start_stack.
4100 * debug.c (scm_m_start_stack): Use scm_start_stack.
4102 * init.c (scm_start_stack, scm_restart_stack): Renamed to
4103 start_stack and restart_stack. (These have static scope.)
4105 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4107 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
4108 readline functions to come in release 2.3. (Thanks to Chet
4110 (handle_errors): Use the above functions.
4112 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4114 * readline.c: Improvements for readline support: Handle errors
4115 better; Implement before-read-hook.
4117 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4119 * init.c (scm_boot_guile_1), readline.c: Test for
4120 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
4121 assure that we have version >= 2.1.)
4123 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
4125 * readline.c (scm_readline): Defer interrupts while we're calling
4128 * readline.c (scm_add_history): Bugfix: Do strdup before giving
4129 away the string to add_history.
4130 (completion_function): Do completion for readline. (Thanks to
4132 (scm_filename_completion_function): New procedure: Filename
4134 (current_input_getc): New function. Use this one instead of
4135 standard getc from readline.
4137 * throw.c, throw.h (scm_handle_by_throw): New function: This
4138 handler throws errors to next handler on the dynwind chain.
4140 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
4142 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
4145 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4147 * procprop.c (scm_i_procedure_arity): New function. Returns arity
4149 (scm_procedure_properties): Modified to return arity together with
4151 (scm_procedure_property): Added the read-only property `arity'.
4152 (scm_set_procedure_property_x): It is an error to set the `arity'
4155 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
4156 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
4158 * procprop.h (scm_sym_arity): New symbol.
4160 * objects.c (scm_set_object_procedure_x): New procedure: Use this
4161 to set the dispatch procedure of an operator or entity object.
4163 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
4164 Made procedure slots read-only.
4166 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
4167 scm_tcs_cons_gloc case in zero args switch; Fixed args
4168 construction for operators in scm_tcs_cons_gloc case in two args
4171 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4173 * fluids.c: Removed use of assert.h (in order to avoid
4176 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
4178 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
4180 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
4181 change makes the evaluator safer at the cost of evaluation speed.
4182 It handles the case when the user has added a non-immediate
4183 improper end of the application form, e.g., `(+ 0 . x)'.
4184 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
4185 minimize the extra cost as much as possible. The new code is
4186 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
4187 problem with structs planted directly in the code (e.g. by a
4188 macro). This no longer causes segmentation fault. (Thanks to
4191 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
4192 arg `proc' in order to be able to throw errors; New argument
4195 * Removed extra #include "debug.h"
4197 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
4199 * scmsigs.c: Declare usleep as returning void on some systems.
4200 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
4203 * coop.c (usleep): Return void on some systems.
4205 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4207 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
4209 * coop.c: Changed return type of usleep to int.
4211 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
4212 isn't found in the OS.
4214 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
4215 isn't enabled. (Thought that I had made this change ages ago...)
4217 * iselect.c: Declare bzero if not defined by OS.
4219 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4221 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
4222 condition. (Thanks to John Tobey.)
4224 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
4225 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
4228 * __scm.h: Start the long-term project of moving to POSIX threads.
4229 Phase 1: Classification of all critical sections.
4230 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
4231 for A sections. (See comments in __scm.h for details.)
4233 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
4234 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
4236 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4238 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
4239 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
4240 (libpath.h, versiondat.h): Replaced dependency on Makefile with
4241 dependencies on $(srcdir)/Makefile.in
4242 $(top_builddir)/config.status in order to avoid circularity.
4244 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
4245 from argc if argc was 0 initially.
4247 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
4248 in generation of libpath.h.
4250 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
4252 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
4253 libguile from 2 to 3.
4255 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
4257 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
4259 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
4261 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
4262 scm_set_port_column_x, scm_port_filename,
4263 scm_set_port_filename_x): Removed optional arguments. Added
4264 proper argument checking.
4266 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
4267 stack size in machine words.
4269 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
4270 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
4271 to Ole Myren Röhne.)
4273 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
4275 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
4276 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
4278 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
4281 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
4282 procedure apply: Copy argument lists before pushing them unto the
4283 environment so that the environment won't get mutated due to
4284 manipulation of procedure arguments. This should perhaps be
4285 regarded as a temporary solution until someone finds a more
4286 efficient one. (Thanks to Maciej Stachowiak.)
4288 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
4290 * script.c (scm_compile_shell_switches): Use "guile" as default
4291 zero arg if argc is NULL.
4293 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
4295 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
4296 is zero. (Thanks to Dirk Herrmann.)
4298 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
4300 * ports.c (scm_add_to_port_table): First line is now line 0
4301 (was 1). (Interface changed according to suggestion by Per
4304 * backtrace.c (display_header): Add 1 to line and column numbers
4305 when presenting them to the user.
4307 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
4308 from debug.c --> eval.c
4310 * eval.h, eval.c (scm_eval_options_interface): New options
4312 (SCM_EVAL_STACK): New option: Size of newly created stacks,
4313 i.e. stacks for new threads.
4315 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
4317 * eval.c (unsafe_setjmp): Removed with #if 0.
4319 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
4322 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
4323 to avoid compiler warnings.
4325 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
4327 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
4329 * throw.c (handler_message): Print message on current error port
4330 instead of default error port. (Thanks to Maciej Stachowiak.)
4332 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
4334 * ports.c (scm_add_to_port_table): allocate in units of
4335 struct scm_port_table *, not struct scm_port_table.
4336 * posix.c (scm_close_pipe): remove the port from the port table
4338 Thanks to Rob Engle for both fixes.
4340 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4342 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
4343 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
4345 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4347 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
4349 * backtrace.c (display_error_body, display_backtrace_body),
4350 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
4351 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
4352 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
4353 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
4356 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
4357 don't receive the jmpbuf arg anylonger.
4358 (scm_catch): Don't accept a #f tag.
4359 (scm_throw): Check that key is a symbol.
4360 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
4362 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
4364 * async.c (async_pending): Removed declaration.
4366 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4368 * dynwind.c (scm_wind_chain): New debug function.
4370 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
4371 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
4372 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
4373 extra layer of functions around the body and handler of a thread.
4374 This extra layer makes sure that the handler is called in the
4375 dynamic context of the surround (= empty dynwind list), but under
4376 the *dynamic root* of the body. We can not use the dynamic root
4377 of the surround since that root belongs to another thread => stack
4378 is not handled correctly. It may seem ugly to use this extra
4379 layer, but the extra cost in terms of execution time is really
4380 negligible compared to the total amount of time required to create
4381 a thread, and it would reduce maintainability to duplicate the
4382 crucial and complicated steps performed by cwdr.
4384 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
4385 (SCM_ALLOW_INTS): Added thread switching code before interrupts
4386 get re-enabled. The important effect of this is that interrupts
4387 are blocked during thread switching so that thread data structures
4388 don't risk getting messed up by an unfortunate signal.
4389 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
4390 seems to do more aggressive optimization which actually move
4391 instructions around in these macros in a fatal way. Therefore:
4392 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
4393 just superstitious...)
4394 (SCM_TICK): Maybe do a context switch and take care of asyncs.
4395 This macro should be used instead of SCM_ASYNC_TICK since the
4396 latter doesn't do context switches any more.
4398 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
4399 instead of SCM_ASYNC_TICK.
4401 * coop.c, iselect.c: Since thread switches are now performed with
4402 interrupts masked, we can't use the old mechanism of delivering
4403 signals immediately when they arrive. Signals must instead be
4404 delivered when the asyncs run *after* the end of the critical
4405 section in scm_internal_select. But this also means after context
4406 switch so that the signal will be delivered to a different thread.
4407 To avoid this, I have changed the protocol of
4408 coop_wait_for_runnable_thread and friends so that they are allowed
4409 to return the original thread. So, if a signal arrives during
4410 scm_internal_select, we won't any longer be forced do a context
4411 switch, but can remain in the same thread and deliver the signal
4414 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
4415 scm_asyncs_pending and made it global.
4417 * iselect.c: Small fixes.
4419 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
4420 coop_condition_variable_init, coop_condition_variable_wait,
4421 coop_condition_variable_signal): Changed return type from `void'
4422 to `int'. This is to adhere closer to the pthreads interface.
4423 This, in turn, is part of an attempt to provide C versions of the
4424 mutex and condition variable primitives which can be part of a
4425 frontend to COOP or pthreads.
4427 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
4428 coop_condition_variable_destroy): New functions.
4430 * coop-threads.c (scm_wait_condition_variable): Use
4431 coop_condition_variable_wait_mutex.
4433 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
4434 Definitions moved to coop-defs.h.
4436 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
4437 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
4438 scm_cond_destroy): New C interface to mutecis and cond vars.
4440 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4442 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
4444 * iselect.c: Now several threads can wait on the same file
4445 descriptor. The behaviour is compatible with OS select: All
4446 threads waiting for the fd return with the same status.
4448 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4450 * coop-threads.c, threads.h (scm_spawn_thread): New function.
4451 Can spawn a thread from application C code.
4453 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4455 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
4456 gh_doubles2scm): New functions.
4458 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
4460 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
4461 commented-out version of gh_eval_str()
4463 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
4465 * socket.c (scm_bind): free soka after use.
4467 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
4469 * stime.c (tzvar): new variable.
4470 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
4471 avoid memory leaks when allocating.
4473 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
4475 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
4478 * gc.c, tags.h: Doc fixes.
4480 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4482 * eval.c (macro-eval!): Removed. This function was a design bug.
4483 It allowed memoized code to leak out to the scheme level. Most
4484 things that you could do with `macro-eval!' can be done with
4487 1997-12-20 Tim Pierce <twp@skepsis.com>
4489 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
4490 scm_fgets now depends on ftell(3) to know how many bytes were
4493 1997-12-15 Tim Pierce <twp@skepsis.com>
4495 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
4496 dealing with strings.
4498 1997-12-13 Tim Pierce <twp@skepsis.com>
4500 Make %read-line more suitable for implementing read-line efficiently.
4501 * ioext.c (scm_read_line): Strip the terminating newline from a
4502 string, and return a cons of the string and its terminator.
4504 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
4505 of the string that is read is stored in this memory location.
4506 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
4507 * genio.c, genio.h (scm_do_read_line): Update caller.
4508 * ports.h (scm_ptobfuns): Update typedef.
4509 * fports.c (scm_fptob, scm_pipob): Update struct.
4511 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4513 * filesys.c (set_element): Return file descriptor.
4514 (fill_select_type): Return the highest file descriptor.
4515 (scm_select): Tell select about the highest file descriptor. On
4516 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
4517 Therefore the extra overhead for calculating the maximum fd seems
4518 to be more than compensated. Is this correct? In any case,
4519 scm_internal_select will be much faster with this info.
4520 (scm_select, fill_select_type, set_element): Don't accept any kind
4521 of object in the file descriptor list or vector.
4523 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4525 * iselect.c (finalize_fd_sets): Bugfix.
4527 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4529 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
4530 when using scm_internal_select (since we might switch to another
4533 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
4535 * simpos.c (scm_system): always define: use sysmissing if not
4536 available. Check for HAVE_SYSTEM instead of _Windows (does
4537 Windows lack system or does it have an unusable one?).
4538 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
4539 Let the argument be optional: if not supplied, call system(NULL).
4541 * ports.c (scm_close_port): relax the type check from OPPORTP to
4542 PORTP; closing a closed port is allowed.
4544 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
4546 * fports.c (scm_fgets): Return if the last char in a chunk is
4547 newline. When fgets returns a string whose length is `size-1', it
4548 is ambiguous whether a whole line was retrieved, so we must check
4549 explicitly whether a line terminator is present.
4551 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4553 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
4554 before taking the CDR. (Thanks to Harald Meland.)
4556 * filesys.c (scm_stat): Slightly optimized.
4558 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
4560 * ports.c (scm_close_port): Make sure the port is open before
4563 * guile-snarf.in: Pass args through to gcc in a way that preserves

4602 --> the_last_stack_fluid.
4604 * backtrace.c: Added #include "fluids.h"

4634 replacement in iselect.c.
4635 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
4636 coop_join): If GUILE_ISELECT enabled, use
4637 coop_wait_for_runnable_thread instead of
4638 coop_next_runnable_thread.
4639 (usleep, sleep): New replacements for system functions if
4640 GUILE_ISELECT is enabled.
4642 * coop-threads.h: Declare coop_wait_for_runnable_thread.
4644 * coop-defs.h (coop_t): Added fields used by scm_internal_select.

4659 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
4660 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
4661 and scm_must_free, since ultimately the string returned will be copied
4662 by scm_makfrom0str anyway. Also, read any characters that may have
4663 been pushed onto the port with scm_ungetc.
4664 * ports.c (scm_generic_fgets): Same as for scm_fgets.
4665 * ioext.c (scm_read_line): Free string after Guilifying it.

4681 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
4682 and to invoke scm_shell().
4683 (gh_launch_pad): took out the loading of boot-9.scm from here,
4684 since it is probably best to let the user control that. In fact,
4685 gh_repl() now invokes scm_shell() which does that.
4687 1997-11-23 Mark Galassi <rosalia@cygnus.com>
4689 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

4714 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
4716 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when

4724 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
4726 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
4727 OPORT is an `open' port, not an output port.

4736 scm_close_all_ports_except, scm_set_current_output_port,
4737 scm_set_current_error_port): Likewise
4738 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
4739 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):

4753 exactly what we want to leave in to detect substrings.
4754 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
4755 * tags.h: Fix diagrams and comments describing the S tag bit;
4756 remove vestigial remarks about the D tag bit.

4758 * strings.c: Formatting tweaks.
4760 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment

4775 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4777 * gh.h: gh_vector_set -> gh_vector_set_x
4779 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4781 * gh_data.c (gh_vector_set_x): changed name to make it consistent

4805 complete the picture R4RS functions that should be mirrored in the
4808 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4810 * tags.h (scm_tc7_substring): Changed the comment and code to
4811 conform with the changes below. Folks! We have suddenly two new
4812 free tc7 codes!!! Jummy, jummy!

4876 * gh_test_c.c (c_vector_test): some improvements on the vector
4879 * gh.h (gh_vector): this used to exist but do the wrong thing.
4880 Now it (almost) does the right thing, though it takes a list
4881 instead of the individual arguments. I need to see how it could
4883 (gh_list_to_vector): added this function as a macro. Corresponds
4884 to Scheme's (list->vector ...).

4892 (gh_make_vector): this used to be (stupidly) called gh_vector().
4893 This is the right name, since it does the same thing as the Scheme
4894 (make-vector ...) procedure.

4913 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
4915 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
4916 macros should by convention not test for NIMPness.)
4917 (SCM_COERCE_OPORT): Adjust indentation.
4919 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added

4943 transformers. (They are always: exp env.); Bugfix: Unmemoize
4944 transformer source with correct environment.

4953 (cwdr_handler): New function.
4954 (scm_internal_cwdr): New function to perform the function of cwdr
4955 but take args that are more useful to C code. Also, the handler
4956 is now invoked *outside* of the new dynamic root, like the docs
4957 say. We no longer have to catch absolutely all errors, the caller
4958 is responsible for using a handler that does not throw, if he
4960 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4961 * root.h (scm_internal_cwdr): New prototype.
4963 Even more but risky streamlining:
4965 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4966 allocation of the jumpbuf of a root continuation. The changes
4967 below are controlled by it. They are now deactivated.
4968 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4969 the JMPBUF of the scm_rootcont to NULL before returning.
4971 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
4972 when they are non-NULL.

4990 (scm_free_print_state): Set `revealed' field to false.
4991 (scm_iprin1): Call user supplied closure printer with
4992 scm_printer_apply. Print in the traditional way when there isn't
4993 one or when it returns #f.
4994 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
4995 Accept a port/print-state pair in addition to just a port.
4996 (scm_prin1): Don't return the print_state to the pool when it has
4998 (scm_printer_apply): Set `revealed' field of print_state to true.
4999 (scm_init_print): Set scm_print_state_vtable.
5000 (print_state_fluid, print_state_fluid_num): Removed.

5007 * Makefile.in: Regenerated with automake 1.2c.
5009 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
5011 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
5012 was looping endlessly.
5014 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
5016 * strports.c (scm_eval_string): Don't close the port.
5018 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
5019 former returns a nice normal integer. (Thanks to Daniel
5022 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
5024 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
5025 makefile variable as a build parameter called LIBS. The
5026 build-guile program will use this, for the time being.
5027 * Makefile.in: Regenerated.
5029 Thanks to Shiro Kawai:
5030 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
5031 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
5034 * Makefile.in: Regenerated with automake 1.2a.
5036 * script.c (scm_compile_shell_switches): If we hit the -c or --
5037 arguments, don't set the car of (command-line) to scm_usage_name,
5038 the prettified name of the guile executable; give it the full
5039 path, the way shells usually handle $0.

5043 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
5044 Scheme-level name `array-map' and renamed `serial-array-map' to
5045 `serial-array-map!'.
5047 * backtrace.c: Introduced exception handlers which now enclose
5048 `display-error' and `display-backtrace' so that error reporting
5049 won't get into infinite loops if an error occurs during displaying
5050 of the error. This can very easily happen with user supplied
5051 print call-back routines.
5053 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5055 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
5056 the names `serial-array-map' and `array-map' should be removed.)
5058 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
5060 * init.c (scm_boot_guile_1): Added scm_init_objects ().
5061 Added #include "objects.h"
5063 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
5064 Add #include "feature.h".
5066 * Makefile.am (libguile_la_SOURCES): Added objects.c.
5067 (modinclude_HEADERS): Added objects.h.
5069 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
5070 This test is needed at many places in the code and should be
5071 abstracted. (Motivated by the need of this test in libguiletk.)
5073 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
5074 (scm_eval_string), load.c (scm_primitive_load,
5075 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
5076 Use SCM_EOF_OBJECT_P.
5078 * eval.c (scm_init_eval): Add feature `delay'.
5080 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5082 * scmhob.h: Removed.
5084 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5086 * list.h (SCM_LISTn): New macros. Make list creation in C code
5087 prettier. The idea comes from STk.
5089 * sequences.h, sequences.c, append.h, append.c: Removed. These
5090 files implemented non-R4RS operations which would encourage
5091 non-portable programming style and less easy-to-read code.
5093 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
5096 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
5097 sequences.h, #include append.h.
5099 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
5102 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
5104 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
5106 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
5108 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5110 * eval.c: Added #include "objects.h"
5112 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
5115 * smob.c (scm_smob_prehistory): Create two objectsmobs with
5116 adjacent smob numbers.
5118 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5120 * procprop.h: Added declaration of scm_i_inner_name.
5122 * gsubr.c: New global symbol scm_i_inner_name.
5124 * debug.c (scm_procedure_name): Try procedure property
5125 `inner-name' if `name' fails.
5127 * print.c (scm_iprin1): Use scm_macro_name.
5129 * eval.c (scm_m_define): Give names to macros as well; Only the
5130 first top-level definition gives a procedure/macro a name.
5131 Otherwise confusing names can turn up in backtraces.
5132 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
5133 `name'; Give names to macros as well.
5135 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
5136 (scm_macro_transformer): Use SCM_CLOSUREP instead of
5139 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5141 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
5143 (prinmacro): Removed. The code has been moved/merged into print.c
5144 in order to decrease code redundancy. We want macros to print in
5145 a way equivalent to procedures, and it would be silly to duplicate
5146 the required code. (We don't want to maintain two places.)
5147 (macrosmob): Print field is now a NULL pointer.
5149 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
5150 scm_macro_transformer): New prototypes.
5151 (scm_tc16_macro): Declared.
5153 * print.c (scm_iprin1): Added code for printing of macros. Macros
5154 are now printed in a way equivalent to procedures.
5156 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
5158 * procs.h (scm_closure_p): Added declaration.
5160 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5162 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
5163 Shouldn't pass "heap" as the subr name.
5165 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
5167 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
5168 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
5169 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
5170 gh_equal_p): Use SCM_NFALSEP, instead of testing against
5171 SCM_BOOL_T. Any non-false value is true.
5173 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5175 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
5176 scm_gensym): Added prototypes.
5178 * symbols.c (scm_gensym): New function. This will speed up
5179 certain types of applications (such as macro systems) which
5180 generate lots of symbols.
5182 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5184 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
5186 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
5188 * unif.c (scm_shap2ra): tighten the checking of the array dimension
5189 specifier, since (2) or (2 . 3) would cause SEGV.
5190 (scm_transpose_array): more argument checking fixes.
5192 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
5194 * Makefile.in: Regenerated.
5196 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
5198 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
5200 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5202 * error.c, error.h (scm_error_callback): Removed (see NEWS).
5204 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
5206 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
5207 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
5210 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
5211 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
5212 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
5213 scm_array_p, scm_array_rank, scm_array_dimensions,
5214 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
5215 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
5216 scm_array_prototype): Added case scm_tc7_wvect.
5218 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
5220 * errno.h: prototype for scm_strerror.
5221 * error.c (scm_strerror): new procedure.
5223 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5225 * list.c (scm_list_append_x): Allow non-pair as last argument.
5226 This is consistent with the R4RS append and is probably the
5227 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
5229 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
5231 * stime.h: prototype for scm_times.
5232 * stime.c (scm_times): new procedure.
5233 * ioext.c (scm_fseek): if the first argument is a file descriptor
5235 (scm_ftell): if the first argument is a file descriptor call lseek
5237 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
5238 * filesys.c (scm_chmod): if the first argument is a file descriptor,
5240 (scm_chown): if the first argument is a port or file descriptor,
5242 (scm_truncate_file): new procedure.
5243 Add DEFER/ALLOW INTS to a few other procedures.
5244 (scm_fsync): new procedure.
5245 (scm_open_fdes): new procedure.
5246 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
5248 (scm_fcntl): the first argument can now be a file descriptor. The
5249 third argument is now optional.
5251 * posix.c (scm_execl, scm_execlp): make the filename argument
5252 compulsory, since omitting it causes SEGV.
5253 (scm_sync): return unspecified instead of #f.
5254 (scm_execle): new procedure.
5255 (environ_list_to_c): new procedure.
5256 (scm_environ): use environ_list_to_c. disable interrupts.
5257 (scm_convert_exec_args): take pos and subr arguments and
5258 improve error checking.
5260 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5262 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
5263 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
5264 argument to SCM_ASSERT. Furthermore, the name of the function
5265 should be passed as first argument when signalling
5266 SCM_WNA. (Thanks to Thomas Morgan)
5268 * gsubr.c (scm_gsubr_apply): From Radey Shouman
5269 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
5270 dispatches on the number of actual args has a default case
5271 reporting an internal error. This is a vestige from a version
5272 that mallocated a SCM vector to hold the arguments. In the
5273 current version this check is too late: if it ever happens we will
5274 have already overstepped the bounds of the array.
5276 Also, the patch [...] adds a check for too many actual arguments."
5278 mdj: Removed check for "internal programming error".
5280 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5282 * gh_io.c (gh_write): New function.
5284 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
5285 throw.c (scm_internal_stack_catch): New sibling to the other catch
5286 functions. Code moved from gh_eval.c.
5287 throw.h: Added header.
5288 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
5289 scm_internal_stack_catch.
5291 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5293 * ioext.h: fix up prototypes.
5294 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
5295 Scheme name is now dup->fdes.
5296 (scm_dup_to_fdes): make the second argument optional and
5297 fold in the functionality of scm_primitive_dup.
5298 (scm_primitive_dup): deleted.
5300 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
5302 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
5303 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
5304 ultrix are defined. Use setvbuf instead of setbuf.
5305 (scm_setvbuf): new procedure.
5306 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
5307 (scm_setfileno): moved from ioext.c.
5308 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
5309 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
5311 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5313 * fluids.c (scm_fluid_p): New function.
5314 * fluids.h (scm_fluid_p): New prototype.

5318 * print.c (scm_iprin1): Enter printed structures into the print
5319 state as nested data while they are printed.
5320 (print_state_fluid, print_state_fluid_num): New variables.
5321 (scm_init_print): Initialize them.
5322 (scm_iprin): If print_state_fluid carries a print_state, use that
5323 instead of creating a new one.
5324 (scm_printer_apply, apply_stub, struct apply_data): New
5325 definitions to help with calling printer functions written in
5327 * print.h (scm_printer_apply): New prototype.
5329 * struct.c (scm_print_struct): Use scm_printer_apply to call the
5330 user defined struct printer.
5332 * dynwind.c (scm_dowinds): Handle fluids on the wind list.
5333 * fluids.h (scm_internal_with_fluids, scm_with_fluids,

5340 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
5341 SCM_ASSERT: arg comes before pos.
5343 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5345 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
5346 to a list of length zero correctly.
5348 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5350 Supply an `fgets' method for port objects to do fast line i/o.
5351 * ioext.c (scm_read_line): New function.
5352 * genio.c (scm_gen_read_line): New function.
5353 * fports.c (scm_fgets): New function.
5354 (scm_fptob, scm_pipob): Add scm_fgets method.

5362 Mon Jul 21 04:03:42 1997 Gary Houston <ghouston@actrix.gen.nz>
5364 * ioext.h: removed scm_duplicate_port prototype.
5366 * ioext.c (scm_primitive_dup2): return the new file descriptor
5367 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
5369 (scm_fdopen): bug fix: don't try to make port unbuffered until its
5370 stream has been set.
5371 (scm_duplicate_port): deleted, there's now an implementation in
5373 (scm_primitive_dup2): do nothing if newfd == oldfd.
5375 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
5377 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
5380 * ioext.h: new prototypes.
5381 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
5383 * fluids.c (next_fluid_num): don't do
5384 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
5386 * ports.h: prototypes too.
5387 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
5389 * fports.h: prototype too.
5390 * fports.c (scm_evict_ports): moved from ioext.c.
5392 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5394 * ports.c (scm_close_port): return a boolean instead of unspecified.
5395 throw an error if an error other than EBADF occurs.
5397 * filesys.h: scm_close prototype.
5398 * filesys.c (scm_close): new procedure, can close file descriptors
5399 and ports (scsh compatible).
5401 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
5404 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
5406 * fluids.c, fluid.h: New files.
5407 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
5408 (modinclude_HEADERS): Added "fluids.h"

5416 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
5417 (scm_make_root): Call scm_copy_fluids to make fluid bindings
5418 unique for the new root when it has a parent.
5420 * smob.h: Include "libguile/print.h" to make scm_print_state
5423 * dynl.c (free_dynl_obj): New function to free the dynamic object
5424 data. (dynl_smob): Use it.
5425 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
5426 the dynamic object data below the linking of the object to avoid
5427 memory leak when the linking code throws an error. Now the code
5428 leaks a whole dynamically linked library when must_malloc throws,
5429 but that should be much less likely.
5431 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
5433 Changes to compile under gnu-win32, from Marcus Daniels:
5434 * stime.c (tzset): If tzset isn't provided, make it a NOP.
5435 (scm_localtime): Change SCM_EOF to SCM_EOL.
5436 (scm_mktime): Likewise.
5437 * socket.c: Don't include sys/un.h unless autoconf tells
5438 us Unix domain sockets are available.
5439 (scm_fill_sockaddr): Ignore Unix domain code.
5440 (scm_addr_vector): Likewise.
5441 (scm_init_addr_buffer): Likewise.
5442 (scm_socketpair): Don't include unless socketpair was

5445 * scmsigs.c (scm_pause): Don't include unless pause was found
5447 * posix.c (scm_getgroups): Don't include unless support function
5448 was found during autoconf (in this case, getgroups).
5449 (scm_setpwent): For setpwent.
5450 (scm_setegid): For setegid.
5451 * net_db.c (scm_inet_netof): Don't include unless support
5452 function was found during autoconf (in this case, inet_netof).
5453 (scm_lnaof): For inet_lnaof.
5454 (scm_inet_makeaddr): For inet_makeaddr.

5466 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
5467 scm_misc_error, not SCM_EOF.
5469 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
5470 arguments for formatting the error message, not SCM_BOOL_F. I
5471 think this is left over from the (eq? '() #f) days.
5473 * read.c (recsexpr): Give this a dummy definition if
5474 DEBUG_EXTENSIONS isn't #defined.
5476 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
5478 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
5481 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>

5486 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
5488 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
5489 alloca.lo will be included in @LIBLOBJS@. Something better than
5490 this should be possible.
5491 * Makefile.in: Regenerated.
5493 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
5495 * simpos.h: prototype for scm_primitive_exit.
5496 * simpos.c (scm_primitive_exit): new procedure, terminates the
5497 process without unwinding the stack.
5499 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
5501 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
5502 argument and logior its components together, so the user doesn't
5503 have to do this explicitly. Also, if regexp/basic is supplied, then
5504 turn off REG_EXTENDED.
5505 (scm_init_regex_posix): New regexp/basic symbol.
5506 (REG_BASIC): #define this if it is not already present.
5508 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5510 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
5511 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
5512 (CLEANFILES): New target, clean versiondat.h, libpath.h.
5513 (DISTCLEANFILES): New target, clean *.x.
5514 * Makefile.in: Regenerated.

5519 years in usage message.
5521 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
5522 * Makefile.in: Regenerated.
5524 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
5525 flag; I don't think we support it.
5526 (scm_make_regexp): Make sure the user doesn't pass the
5529 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
5531 (scm_init_regex_posix): Define constants for the REG_mumble flags;
5532 name them according to the SCSH convention: regexp/mumble.
5534 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
5536 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
5538 * Makefile.am (libpath.h): Include the values of all the standard
5539 Makefile directory variables. Print a message, but don't print
5541 (versiondat.h): Print a message, but don't print all the commands.
5542 * load.c: #include "alist.h".
5543 (init_build_info): New function.
5544 (scm_init_load): Call it.
5545 * Makefile.in: Regenerated.
5547 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
5549 * root.c: Establish a reliable catch-all handler for the new root.
5550 After all the Scheme handler function might signal an error too,
5551 and we don't want to lose that.
5552 (cwdr_inner_body): Renamed from cwdr_body.
5553 (cwdr_outer_body): New function, to establish the user's handler,
5554 and pass control to cwdr_inner_body.
5555 (cwdr): Establish the reliable catch-all handler here, and pass
5556 control to cwdr_outer_body.
5557 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
5558 the user's handler through to cwdr_outer_body.
5559 * throw.c (scm_handle_by_message): Move guts into....
5560 (handler_message): New static function.
5561 (scm_handle_by_message_noexit): New function.
5562 * throw.h (scm_handle_by_message_noexit): New prototype.
5564 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
5565 across this. Only works on GCC. Otherwise, we hope for the best.
5566 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
5567 the feeling that real thread systems will not need this...
5569 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
5571 Try to detect when people are using one version of libguile and a
5572 different version of ice-9. People have been skewing things and
5573 sending in bug reports.
5574 * Makefile.am (versiondat.h): New file to generate.
5575 * version.c: #include "versiondat.h", to get version info.
5576 (scm_libguile_config_stamp): New function.
5577 * script.c: #include "version.h".
5578 (scm_compile_switches): Call scm_version to get version number.
5579 * scmconfig.h.in, Makefile.in: Regenerated.
5580 * Makefile.in: Regenerated.
5582 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
5583 primitive definitions under their Scheme names.
5585 * Makefile.am (libguile_la_LDFLAGS): Update library version to
5586 1:2. Helps avoid confusion between installed and uninstalled libs.
5588 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
5591 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
5592 backslash from definition; this should be used like: GDB_INTERFACE;
5594 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5596 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
5597 new port unbuffered until its stream has been set.
5599 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
5601 * ports.h: new prototype.
5602 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
5604 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
5606 Make things compile neatly under Sun's C compiler.
5607 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
5608 * extchrs.c (xmbtowc): Make the second arg a normal char, not
5609 unsigned, because that's what the ANSI function takes.
5610 * extchrs.h (xmbtowc): Corresponding change to prototype.
5611 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
5613 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
5614 argument plain char *.
5615 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
5617 * tag.c (scm_tag): Remove unreachable statement.
5618 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
5619 top of the word, it should be unsigned.
5621 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
5622 is defined, to avoid warnings; it's only used in the
5623 conflict-checking code. Which might go away anyway.
5624 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
5625 conditionals; put the label definition in an #if too, to stifle
5628 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
5629 ChangeLog-threads in the distribution.
5630 * Makefile.in: Regenerated.
5632 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5634 * guile-snarf.in: Changed regexp to support CPPs that insert
5635 whitespace between lexical tokens (which munges the `%%%' snarf
5638 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5640 * load.c (scm_init_load_path): Append $(datadir)/guile to
5641 %load-path, so modules do not have to be installed in Guile's
5642 current version directory.
5644 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
5646 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
5647 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
5648 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
5649 call the sysdep functions with deferred ints.
5650 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
5651 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
5652 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
5655 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
5658 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
5660 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
5662 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
5664 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
5667 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
5669 * eval.c (scm_lookupcar1): New procedure to cope with a race
5670 condition during lookup (when using threads).
5671 (scm_lookupcar): Implement in terms of scm_lookupcar1.
5672 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
5675 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
5677 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
5678 supplied. (Change from Tim Pierce.)
5680 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
5682 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
5683 23:47:01 1997" changelog: Slots are now initialized with `#f' by
5684 default and not `()'. `#f' is the canonical non-value in Scheme,
5687 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5689 * struct.c (struct_printer): New variable that holds a handle on
5690 the Scheme variable *struct-printer*. This variable can be set by
5691 Scheme code to override the printing of structures.
5692 (scm_print_struct): If struct_printer is set, call it. If it is
5693 not set, or returns #f, print the structure in the old fashion.
5694 Include "eval.h" for scm_apply.
5696 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
5698 * struct.c (scm_struct_ref, scm_struct_set_x): Use
5699 scm_struct_i_n_words to get the number of fields, not
5700 -scm_struct_n_extra_words.
5702 On the route to fancier struct printing:
5703 * struct.c (scm_print_struct): New function to print a structure.
5704 Include "genio.h" to support it. This function doesn't do
5705 anything interesting right now, but I think it should be here
5707 * struct.h: Include "print.h" and add prototype for
5709 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
5710 print structures ourself.
5712 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5714 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
5715 before applying the handler in case it doesn't return.
5717 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
5719 * scmsigs.h, async.h: updated.
5721 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
5724 * posix.c (scm_uname): interpret only negative values as an error.
5725 Solaris normally returns a positive value.
5727 * script.c (scm_compile_shell_switches): if we are not going into
5728 an interactive repl, set scm_mask_ints to zero so that asyncs can
5731 * simpos.c (scm_system): don't ignore/unignore signals around
5734 * posix.c (scm_open_pipe): don't ignore/unignore signals around
5737 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
5738 done in boot-9.scm instead.
5740 * scmsigs.c, async.c: Major rewriting of signal handling code.
5741 (scm_sigaction): new procedure.
5742 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
5744 (scm_raise): return unspecified, throw error on failure.
5746 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5748 * regex-posix.c (scm_init_regex_posix): Register the "regex"
5749 feature, to help boot-9.scm decide whether to import the regex
5752 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5754 * eval.c: Include scmconfig.h at the beginning of the file so that
5755 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
5758 * regex-posix.c: #include "_scm.h" before conditionally #including
5759 <regex.h>; the former defines HAVE_REGCOMP.
5761 * regex-posix.c: #include <regex.h> conditionally, so the file is
5762 CPP'able (for dependency scanning) even on systems that don't have
5765 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5767 Add new R4RS-compliant syntax for keywords.
5768 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
5769 regardless of the setting of the `keywords' read option.
5770 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
5771 can be re-read no matter what the setting of the `keywords' read
5774 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
5776 Add support for POSIX regular expressions.
5778 * regex-posix.c, regex-posix.h: New files. (Some code
5779 is taken liberally from rx/rgx.c in the old Guile dist.)
5781 * init.c: Include regex-posix.h.
5782 (scm_boot_guile_1): Call scm_init_regex_posix.
5784 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
5785 Add regex-posix.[ch] sources.
5786 * Makefile.in: Regenerated.
5788 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
5789 to do this automatically? It didn't for me, bleh.)
5791 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
5793 * fports.c (print_pipe_port): New function.
5794 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
5795 latter doesn't even take the right arguments.
5797 * Makefile.am: Increment shared lib revision number. I think
5798 sometimes the uninstalled Guile finds the installed shared lib;
5799 Gord says doing this might help. As things turned out, I can't
5800 say whether it does.
5801 * Makefile.in: Regenerated.
5803 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
5804 passing it as the closure argument to scm_boot_guile. (Bill
5807 * ports.c (print_void_port, putc_void_port, puts_void_port,
5808 write_void_port, flush_void_port, getc_void_port, close_void_port,
5809 noop0): Use ANSI prototypes instead of K&R declarations, so the
5810 initialization of void_port_ptob gets aggressively type-checked.
5811 Fix arguments of print_void_port and write_void_port. (Bill

5845 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
5847 * script.c (scm_find_executable): Use prototype-style definition
5848 here; apparently it's not quite right to have const in a prototype
5849 and then use a K&R declaration. I wonder if stuff like this will
5850 go away if we compile with -Wrequire-prototypes, or whatever that
5851 is... (Bernard URBAN)
5853 * scmhob.h: New text from Bernard URBAN.
5855 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5857 * script.c: Don't #define const on hpux. Configure takes care of
5858 this. (Thanks to Larry Schwimmer.)
5860 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
5861 decide whether to #include <unistd.h>, instead of listing a bunch
5862 of systems. Don't #include stdio twice. Removed dyked-out
5863 definition of scm_find_impl_file.
5865 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5867 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
5868 library version info to 1:0.
5869 * Makefile.in: Regenerated.
5871 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

5875 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
5876 throw.c: Update copyright years; these files have been worked on
5877 significantly in 1997, but only had copyright years for 1996.
5878 Also, change name of copyright holder on some from Mikael
5879 Djurfeldt to Free Software Foundation; he has signed papers
5880 assigning the changes to the FSF.
5882 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
5883 reason not to give the user the option.
5885 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5886 Return #f on end-of-file when scanning table (i.e. when called
5887 with no arguments). Try to catch errors, when we can.
5888 * posix.c (scm_getgrgid, scm_getpwuid): Same.
5890 * script.h (scm_shell_usage, scm_compile_shell_switches): New
5891 external declarations. These are useful.
5893 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
5895 * posix.c: don't include <sys/select.h> or define macros for
5896 select, since they were not used in this file.
5898 * filesys.c (scm_select): make the fifth parameter microseconds,
5899 not milliseconds. let the fourth parameter be either a real value
5900 or an integer or #f. The first, second and third arguments can
5901 now be vectors: the type of the corresponding return set will be
5903 (set_element, get_element): new static procedures.
5905 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
5907 * strports.c (scm_eval_string): New function.
5908 (scm_eval_0str): Trivially re-implemented in terms of
5910 * strports.h (scm_eval_string): New extern decl.
5912 * net_db.c (h_errno): Add extern decl for this.
5914 * fports.c (local_pclose): New function.
5915 (scm_pipob): Use it in the initializer here.
5918 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
5919 Use a meaningful error message when signalling an error. For
5920 this, scm_gethost must check h_errno rather than errno.
5922 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
5924 * Makefile.in: Regenerated, using automake-1.1p.
5926 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5928 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
5929 not SCM_UNSPECIFIED.
5931 * script.c (scm_compile_shell_switches): don't append (quit) if
5933 (scm_shell): call scm_exit_status and exit on the result of the
5936 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
5938 Ensure that shared substrings are handled properly when passed to
5939 a system call or other foreign function. Many thanks to Tim
5941 * symbols.h (SCM_COERCE_SUBSTR): new macro.
5942 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
5943 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
5944 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

5965 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5967 * dynl-shl.c: Completely replaced with new code from Bernard
5970 * script.c (scm_ice_9_already_loaded): New variable.
5971 (scm_compile_shell_switches): Use it.
5973 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5975 * filesys.c (scm_input_waiting_p): add missing third argument to
5978 * stime.c (scm_localtime): copy the result of localtime before
5979 calling gmtime in case they share a buffer.
5980 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
5983 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5985 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
5987 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
5989 * Makefile.am (check-local): New target, which causes 'make check'
5990 to run gh_test_c and gh_test_repl, with some trivial input.
5991 * Makefile.in: Rgnrtd.
5993 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
5995 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
5998 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
6000 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
6001 sure how this was supposed to work.
6002 (scm_async_click): don't send SCM_TICK_SIGNAL.
6003 (scm_init_async): don't initialize %tick-thunk.
6005 * the following change doesn't affect the Scheme interface:
6006 gc-thunk is called at the end of garbage collection. however it's
6007 no longer implemented by pretending it's a signal.
6009 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
6010 system async corresponding to scm_gc_thunk.
6011 * async.h: declare scm_gc_async.
6012 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
6013 gc-thunk directly, instead of going through a signal handler.
6014 (scm_gc_async): new variable, points to the GC system-async.
6015 (scm_init_async): save the GC async as scm_gc_async instead
6016 of using system_signal_asyncs.
6017 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
6019 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
6021 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
6022 Don't screw up if we're interrupted.
6023 * Makefile.in: Regeneradet.
6025 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
6027 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
6029 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
6030 we're not using AM_INIT_GUILE_MODULE any more.
6031 * Makefile.in: Reneregated.
6033 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
6035 Functions for finding variable bindings, grace à Tim Pierce.
6036 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
6037 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
6039 Get 'make dist' to work again.
6040 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
6041 * Makefile.in: Regenerated, like a surry without a fringe on top.
6043 Changes for reduced Guile distribution: one configure script,
6045 * configure.in, configure: Removed.
6046 * acconfig.h, acinclude.m4: Moved to parent directory, where the
6047 real configure script lives.
6048 * Makefile.in, scmconfig.h.in: Regenerated.
6050 * init.c: #include "script.h", to get prototype for script.c's
6053 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
6055 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
6056 scm_must_malloc, not raw malloc.
6058 * script.c (scm_compile_shell_switches): Dyke out debugging output
6061 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6063 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
6065 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
6066 system has them. Hope this is safe. Previously
6067 sys/timeb.h was included if HAVE_FTIME was defined or if
6068 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
6069 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
6071 * ioext.c (scm_setfileno): add missing third argument to
6072 scm_misc_error call.
6074 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
6076 * eq.c (scm_equal_p): Correctly compare strings of different
6077 varieties. (Thanks to Tim Pierce.)
6079 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
6081 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
6082 #! block comment must occur on a line all by itself.
6084 Move most of the guts of shell command processing into libguile,
6085 so guile.c can be very small (and eventuallly auto-generated. (I
6086 mean, generated mechanically, not self-generated. Hmm.))
6087 * guile.c, script.c, script.h: New source files.
6088 * init.c (scm_boot_guile_1): Call scm_init_script.
6089 * libguile.h: #include "script.h".
6090 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
6091 targets, for new executable.
6092 (libguile_la_SOURCES): Mention script.c.
6093 (modinclude_HEADERS): Add script.h.
6094 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
6095 not dynamic linking is enabled. This is because we're generating
6096 executables now. Move CY_AC_WITH_THREADS call after those, so the
6097 values of cy_cv_threads_libs captures the libs chosen above.
6098 * Makefile.in, configure, aclocal.m4: Regenerated.
6100 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
6101 We don't maintain this interface any more, and it just confuses
6104 * alloca.c: #include <scmconfig.h>, not <config.h>.
6105 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
6106 it'll get included in disties.
6108 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
6110 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
6111 be distributed, because they confuse people.
6112 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
6114 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
6116 * configure.in: check for presence of gethostent (not present on
6117 OpenBSD by default).
6118 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
6119 * configure, scmconfig.h.in: Regenerated.
6121 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
6123 * backtrace.c (scm_backtrace): Split message string across
6124 newlines properly. GCC is more tolerant of this than other
6127 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
6129 Merge threads directory into libguile.
6130 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
6131 threads.h: New source files.

6133 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
6135 (modinclude_HEADERS): Add threads.h, coop-defs.h.
6136 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
6137 coop-threads.c.cygnus, coop-threads.h.cygnus.
6138 * configure.in: If we're using threads, include threads.o in
6140 * _scm.h, libguile.h: threads.h lives in this directory now.
6141 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
6142 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
6143 currently used, but brought along for information's sake.
6144 * ChangeLog-threads: log from old 'threads' directory.
6145 * Makefile.in, configure: Rebuilt.
6147 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
6149 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
6152 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
6154 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
6156 Merge GH interface library into libguile.
6157 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
6158 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
6159 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
6160 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
6162 (EXTRA_libguile_la_SOURCES): ... here.
6163 (pkginclude_HEADERS): Add variable, to get gh.h installed.
6164 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
6165 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
6166 New variables, describing how to build the gh test programs.
6167 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
6168 build the test programs, and we probably should have been linking
6169 libguile.la against them all along, to support AIX shared libs.
6170 Add cflags for threads to CFLAGS; add libs for threads to new
6171 variable THREAD_LIBS, used in Makefile.am.
6172 * ChangeLog-gh: log from old `gh' subdirectory.
6173 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
6175 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
6177 * acconfig.h: Undo change of Apr 9; including the definition of
6178 PACKAGE in the guile headers conflicts with applications' own
6180 * scmconfig.h.in: Regenerated.
6182 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

6189 when PROC is receiving no arguments.
6191 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
6193 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
6194 have S_IFSOCK. This is the case under Ultrix.
6196 * posix.c (scm_status_exit_val, scm_status_exit_val,
6197 scm_status_term_sig, scm_status_stop_sig): Modified to work with
6198 Ultrix versions of WIFSTOPPED, etc., which assume that their
6199 arguments are lvalues (hmm).
6201 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
6203 * eval.c: Doc fixes.
6205 * throw.c: Doc fixes; rearranged.
6207 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
6209 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
6211 * acconfig.h: Added entry for PACKAGE.
6212 * scmconfig.h.in: Regenerated.
6214 Changes to work with automake-1.1n, which has better libtool support.
6215 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
6216 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
6218 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
6220 * Makefile.in: Rebuild.
6222 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6224 * stime.c (scm_mktime): take an optional zone argument.
6225 (scm_localtime): check putenv return value.
6226 (scm_strftime, scm_strptime): moved from posix.c. move #include
6228 stime.h, posix.h: update prototypes.
6229 (bdtime2c, setzone, restorezone): new static procedures.
6230 (scm_mktime, scm_strftime): use them.
6231 (scm_strftime): don't call mktime before strftime. Use
6232 filltime for return value.
6233 (filltime): convert NULL zname to #f.
6234 (scm_strptime): return a count of characters consumed, not
6235 the remaining string.
6237 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6239 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
6240 (scm_mktime): likewise.
6242 Uncomment localtime and mktime.
6244 * configure.in: add AC_STRUCT_TIMEZONE.
6246 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
6248 * stime.c (scm_init_stime): don't define ticks/sec.
6249 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
6250 return value problem and is still portable.)
6252 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6254 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
6255 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
6256 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
6257 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
6258 cpp_err_symbols.c): Corresponding changes.
6259 * Makefile.in: Regenerated.

6263 * posix.c (scm_putenv): don't check HAVE_PUTENV.
6264 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
6265 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
6266 * putenv.c: new file, from sh-utils 1.12.
6268 * posix.c (scm_environ): use malloc in place of scm_must_malloc
6269 since allocation isn't for Scheme objects.
6270 (scm_putenv): copy strings before placing in the environment.
6272 * stime.c (scm_current_time): throw an error if time returns -1,
6273 instead of returning #f.
6274 (scm_get_internal_real_time, scm_get_internal_real_time): use
6275 scm_long2num for return value instead of SCM_MAKINUM.
6277 * stime.h: prototypes updated.
6279 * stime.c (scm_time_in_msec): apparently unused, deleted.
6281 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
6283 * configure.in: check for gettimeofday.
6285 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
6286 which may be more usefully portable than a gettimeofday interface.
6288 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
6290 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not

6294 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6296 * stime.c (filltime): recovered static procedure.
6297 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from

6301 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
6303 * posix.c (scm_mknod): split the mode argument into type and perms
6304 arguments, like the extra fields returned by stat.
6306 * fports.c (scm_pipob): set the close, free and print procedures.
6307 (scm_close_pipe): new procedure.
6309 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
6310 define them in boot-9.scm
6312 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6314 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
6315 wan't defined. Don't include fd.h.
6317 * Previously fd.h was regenerated whenever configure was run,
6318 forcing a couple of files to be recompiled.
6320 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
6321 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
6322 Check for _fileno as well as _file.
6324 * ioext.c: don't fd.h.
6325 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
6328 * Change the stratigy for getting information about errno
6329 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
6330 generating lists of symbols during the build process, which will
6331 not always work, include comprehensive lists in the distribution.
6332 To help keep the lists up to date, the "check_signals" and
6333 "check_errnos" make targets can be used.
6335 * configure.in: don't check for a command to extract errno codes.
6336 * Makefile.am: update file lists, remove errnos.list and errnos.c
6337 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
6338 check_errnos targets.
6339 (CLEANFILES): remove errnos.c and errnos.list, add
6340 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
6341 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
6342 * errnos.default: deleted.
6343 * cpp_signal.c: new file.
6344 * cpp_errno.c: renamed from errnos_get.c.
6345 * cpp_err_symbols, cpp_sig_symbols: new files.
6346 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
6347 * error.c (scm_init_error): #include cpp_err_symbols instead of
6349 * posix.c (scm_init_posix): don't intern signal symbols. #include
6352 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
6354 * strop.c (scm_i_index): allow the lower bound to be equal to the
6355 length of the string, so a null string doesn't always give an error.
6357 * posix.h: new prototypes.
6358 * posix.c (scm_status_exit_val, scm_status_term_sig,
6359 scm_status_stop_sig): new functions, as in scsh. They break down
6360 process status values as returned by waitpid.
6362 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
6364 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
6365 configure doesn't know about it.
6367 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6369 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
6371 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
6372 which defines C variables with global linkage.
6374 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6376 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
6379 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
6381 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
6382 has time to check why this doesn't work well with continuations.
6384 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
6386 * Fix shell syntax error; some shells won't tolerate
6387 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
6389 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
6391 * posix.c (scm_uname): throw an error if uname fails instead
6394 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
6396 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
6399 * async.c (scm_ints_disabled): definition moved from error.c.
6401 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6403 * acconfig.h: Removed PACKAGE.
6405 * scmconfig.h.in: Regenerated.
6407 * snarf.h: g++ says it's non-portable not to specify the first
6408 argument in a varargs declaration. I introduced the first
6409 argument by using preprocessor conditionals.
6411 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
6413 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
6414 (scm_freopen): use RO string macros for filename and modes.
6415 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
6417 * posix.c (scm_getgrgid): simplify conversion of name to C string.
6418 (scm_mknod): use RO string macros for path.
6420 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
6421 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
6423 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
6424 use SCM_ROSTRINGP and SCM_ROCHARS.
6426 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6428 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
6431 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
6432 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
6433 support for byte vectors.
6435 * print.c (scm_iprin1): Limit number of vector elements printed
6436 according to pstate->length.
6438 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6440 * backtrace.c (scm_display_error_message): don't segv if message
6443 * error.h: prototype for scm_error_scm.
6445 * error.c (scm_error_scm): new procedure, reimplements scm-error
6446 in C and uses scm_error.
6448 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6450 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
6451 pointer to the Scheme variable read-hash-procedures and intern it
6452 in scm_init_read. Modify scm_read_hash_extend and
6453 scm_get_hash_procedure to use the pointer.
6455 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6457 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
6458 (SCM_KEYWORD_STYLE): defined.
6460 * read.c (scm_read_opts): add a keywords option. This isn't a
6461 boolean option, in case someone wants to add support for DSSSL
6463 Setup scm_keyword_prefix symbol.
6464 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
6466 I've left keyword support disabled by default, since it doesn't
6467 seem to break the module system and it gives R4RS standard behaviour.
6468 It can be reactivated with (read-set! keywords 'prefix).
6470 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6472 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
6473 before constructing arbiter.
6475 * eval.c (scm_m_define): Bugfix: Check that the object is a
6476 closure before setting the procedure property!
6478 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
6480 * ports.c: Removed `ungetc-char-ready?'.
6482 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
6484 * read.c (scm_init_read): intitialise scm_read_hash_procedures
6485 (idea from Mikael: make it a pair so scm_permanent object only
6487 (scm_read_hash_extend): don't call scm_permanent_object.
6488 (ideas from Mikael): if chr is already in the list, replace its
6489 procedure instead of appending it again. If proc is #f, remove
6491 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
6493 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
6495 * gdbint.c (gdb_read): update scm_lreadr usage.
6497 * load.h: update prototypes.
6499 * load.c (scm_primitive_load, scm_read_and_eval_x,
6500 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
6502 * read.h: add prototype for scm_read_hash_extend. Change args for
6505 * read.c (scm_read_hash_procedures): new variable.
6506 (scm_read_hash_extend): new procedure.
6507 (scm_get_hash_procedure): new procedure.
6508 (scm_lreadr): use scm_get_hash_procedure instead of an argument
6509 for extended # processing.
6510 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
6511 scm_read_token): remove case_i, sharp arguments. Change callers.
6513 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
6515 * read.h (SCM_N_READ_OPTIONS): increase to 3.
6516 (SCM_CASE_INSENSITIVE_P): define.
6518 * read.c: add case-insensitive option to scm_read_opts.
6519 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
6520 to determine whether to convert symbol case.
6521 (default_case_i): definition removed.
6522 * read.c (scm_read_token): if case_i, downcase ic before doing
6525 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6527 * configure.in: Added configuration option `guile-debug'.
6528 Configure with --enable-guile-debug if you want a bunch of extra
6529 functions used for debugging when developing Guile.
6531 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
6533 * procs.c (make-cclo): New undocumented debugging procedure: Make
6534 compiled closure with internal procedure PROC and length LENGTH.
6535 Only compiled if GUILE_DEBUG is defined.
6537 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
6539 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
6541 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
6543 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
6544 with 3 or more args internally to the evaluator.
6546 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6548 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
6549 with 3 or more args internally to the evaluator. This is mainly
6550 because we don't want to pass entry and exit points of the
6551 debug support twice, but it also seems to increase the speed of
6552 the evaluator for such calls (e. g. (+ 1 2 3)).
6554 * backtrace.c (scm_display_application): New procedure:
6555 display-application; Set fancy printing parameters individually
6556 for different types of display (backtrace, error, application).
6557 (These should of course be customizable!)
6559 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
6560 clear the CHECK-flags.
6562 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6564 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
6566 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6568 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
6569 from pairs with a GLOC in the car.
6571 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
6572 otherwise `symbol-hash' will behave badly.
6573 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
6574 we get segmentation fault!
6576 * symbols.c: Added #include "weaks.h". New functions:
6577 `builtin-bindings' and `builtin-weak-bindings'. (These will be
6578 moved to an extraneous library when we split libguile.)
6580 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6582 * filesys.c (scm_stat): stat now takes fport arguments too as
6583 documented in the manual.
6585 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6587 * debug.c (scm_single_step): Bugfix: Call continuation with
6588 scm_call_continuation instead of throwing to it.
6590 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
6592 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
6593 argument wasn't declared to be optional.
6595 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6597 * stime.c (scm_init_stime): Add feature "current-time".
6599 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6601 * throw.h: prototype for scm_exit_status.
6602 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
6603 args to derive an exit status. Allows (quit) to work from a
6605 (scm_exit_status): new function.
6608 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6610 * eval.c (scm_deval): Removed some old code.
6611 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
6613 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
6616 * symbols.c (msymbolize): Bugfix: Must initialize property list to
6619 * procs.c: Introduce the existent C function scm_thunk_p at the
6620 Scheme level as well.
6622 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6624 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
6625 used from C to easily lookup the value of a symbol in the current
6628 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6630 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
6631 scm_init_unif in this file. This will also fix a previous problem
6634 * configure.in: Added AM_MAINTAINER_MODE
6636 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6638 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
6641 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6643 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
6644 source files that are not always included in libguile but should
6645 have their dependencies calculated by automake. This variable is
6646 recognized by automake, no further magic is needed.
6647 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
6648 to deal exclusively with *.lo files, as it seems. The *.o files
6649 are built automatically when the corresponding *.lo file gets
6652 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
6654 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
6657 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
6659 * unif.c (scm_array_set_x): minor change to argument error checking.
6661 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
6663 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
6664 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
6665 They should only be included in the library at configure.in's
6667 (libguile_la_LDADD): Include the appropriate .lo files here.
6668 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
6669 so we know when to build them (and their .lo bretheren).
6670 * configure.in (LIBLOBJS): New substituted variable. We let
6671 configure decide which .o files to include in LIBOBJS, and then
6672 put the corresponding list of .lo files in LIBLOBJS. The latter
6673 is what we pass to libtool.
6674 * Makefile.in, configure: regenerated.
6676 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
6678 * symbols.c (scm_sysintern0): New function. Contains the core of
6679 old scm_sysintern but doesn't take a second value argument.
6680 (scm_sysintern): Now uses scm_sysintern0.
6681 (scm_sysintern_no_module_lookup): Renamed to
6682 scm_sysintern0_no_module_lookup and doesn't take a second value
6683 argument any longer.
6685 * symbols.h (scm_sysintern0: Added declaration.
6687 * options.c (scm_init_opts): Use scm_sysintern0 instead of
6688 scm_sysintern when interning option keys. Otherwise we risk
6689 destroying the values of already interned variables.
6691 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
6692 scheme-level boolean (use SCM_NFALSEP).
6694 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
6696 (scm_backtrace): New function. (C version of old function from
6697 boot-9.scm) Motivation: Make it possible to display backtraces
6698 without depending on boot-9.scm. (I'm uncertain if this
6699 motivation is good enough...)
6701 * root.h (scm_root_state): Add member the_last_stack_var.
6702 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
6704 * root.c (mark_root): Mark scm_the_last_stack_var.
6706 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
6709 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
6711 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
6712 1. mark_lazy_catch didn't mark the smob.
6713 2. Both functions above have standard variants:
6714 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
6715 free_lazy_catch --> scm_free0.
6717 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
6719 * throw.c (scm_internal_lazy_catch): New function.
6720 (scm_lazy_catch): Rewritten to use it.
6721 (scm_ithrow): Handle the new lazy catch representation.
6722 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
6723 that doesn't have a jmpbuf is a lazy catch clause.
6724 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
6725 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
6726 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
6728 (scm_init_throw): Register the new lazy-catch smob type.
6729 * throw.h (scm_internal_lazy_catch): decl for new function.
6731 * throw.c (scm_internal_catch): Doc fixes.
6733 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
6734 configure.in. Including this might cause problems if applications
6735 that link against libguile include their own copies of alloca, but
6736 if they're using autoconf, they should be adding libguile to LIBS
6737 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
6738 the copy in libguile, and things will be okay. (I think.)
6740 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6742 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
6744 strop.h: move prototypes too.
6746 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6748 * posix.c (scm_init_posix): don't intern EINTR since it's now done
6751 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
6752 etc. I deleted them from filesys.c long ago, but didn't
6753 notice they were here too (although ineffective since
6754 sys/stat.h wasn't included).
6756 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
6758 * eval.c: Don't define alloca in GCC case. gcc will automatically
6759 use __builtin_alloca if appropriate.
6761 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
6763 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
6764 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
6765 that values of automatic variables are preserved. See comments
6766 for safe_setjmp for details.
6768 Change from Thomas Morgan:
6769 * variable.c: Include eq.h.
6770 (var_equal): New function.
6771 (variable_smob): Use var_equal as the discriminator for variables.
6773 * throw.c (s_throw): Remove extraneous declaration.
6775 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
6776 * eval.c: Add necessary CPP cruft to support that.
6777 * configure, Makefile.in, scmconfig.h.in: regenerated.
6779 Change from Thomas Morgan:
6780 * procprop.c (scm_procedure_properties): Convert the Scheme
6781 boolean returned by scm_procedure_p into a C boolean before using
6782 it as a condition for SCM_ASSERT.
6783 (scm_procedure_property): Likewise.
6785 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
6786 indications of Unixness.
6789 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6791 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
6793 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6795 * read.c (scm_lreadr): use scm_misc_error to improve one of the
6796 "unknown # object" error messages.
6798 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
6799 (scm_i_index) and declare it static. Add a 'direction' argument
6800 to indicate what way the search should go.
6801 (scm_i_index): throw out-of-range error instead of wrong-type-arg
6803 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
6804 strop.h: remove scm_i_index, scm_i_rindex prototypes.
6806 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6808 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
6810 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
6811 to avoid clash with various scsh forks.
6813 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
6815 The following two changes (ramap.c, throw.c) are motivated by the
6816 apparent unportability of forward declarations of static arrays of
6817 the form `static foo bar[];'.
6819 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
6820 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
6822 * throw.c (scm_throw): Moved above scm_ithrow.
6824 * options.h: Removed the extern declarations of scm_yes_sym and
6825 scm_no_sym since these are static.
6827 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6829 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
6831 * Makefile.am: remove AWK=@AWK@.
6832 Add a rule for generating errnos.list.
6833 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
6835 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
6836 don't extract errnos, just set a variable (avoids the
6837 need to recompile error.c just because configure is run.)
6839 * unif.h: update prototypes.
6840 * unif.c (scm_uniform_array_read,write): change the offset and
6841 length arguments to start and end, for consistency.
6843 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
6845 * ioext.h: update prototypes.
6846 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
6847 scm_read_line_x, it's a more general procedure using an
6848 interface from scsh. read-line and read-line! are now defined
6850 Note that the new read-line trims the terminator
6851 by default, previously it was appended to the returned string. An
6852 optional argument specifies how to process the terminator (scsh
6853 compatible). For the old behaviour: (read-line port 'concat).
6854 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
6855 returns a pair, but is converted to multiple values if the scsh
6858 socket.h: update prototypes.
6859 * socket.c (scm_recvfrom): for consistency with other procedures,
6860 take start and end as separate optional arguments.
6861 (scm_recv, scm_recvfrom): don't allow the second argument
6862 to be a size, only a buffer. Change the scheme names to
6863 recv! and recvfrom!. Don't return the buffer.
6865 * ioext.h, posix.h: move prototypes too.
6866 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
6867 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
6868 "read.h" and "unif.h".
6869 * ioext.c: include "chars.h"
6871 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
6873 * dynl.c: The dynamic linking and module registration functions
6874 are now defined even when dynamic linking is not available for the
6875 host system. Some of their functionality can be done without
6876 dynamic linking; when it's really needed, they throw errors.
6878 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
6880 * configure.in: Only define DYNAMIC_LINKING when one of the system
6881 dependent functions is detected.
6882 * dynl.c (scm_dynamic_func): New function to get the address of a
6883 function in a dynamic object.
6884 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
6885 produced by scm_dynamic_func as the thing to call.
6887 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
6889 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
6890 (scm_register_module_xxx, scm_registered_modules,
6891 scm_clear_registered_modules): New functions.
6893 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
6895 * symbols.c (scm_sysintern): Renamed to
6896 scm_sysintern_no_module_lookup.
6897 (scm_sysintern): New function to take the place of the old
6898 scm_sysintern. It uses the current toplevel lookup closure to give
6899 the symbol its value. This is a temporary hack to put packages
6900 like gtcltk into their own module.
6901 (scm_can_use_top_level_lookup_closure_var): New variable to tell
6902 us whether `scm_top_level_lookup_closure_var' has been initialized
6904 * eval.c (scm_init_eval): Set it.
6906 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6908 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
6909 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
6911 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
6913 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
6914 scm_sys_dup): deleted: FD capability will be added to other
6916 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
6917 scm_fd_free, fd_smob, scm_intern_fd.
6918 (scm_open): renamed from scm_sys_open. Return a port instead of
6919 an FD object. Make the mode argument optional.
6920 (scm_sys_create): deleted, it's just a special case of open.
6921 (scm_init_filesys): move interning of constants O_CREAT etc.,
6922 here (were previously using SCM_CONST_LONG macro).
6923 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
6925 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
6926 include "fports.h" and <stdio.h>
6927 (scm_stat, scm_select): don't support FD objects.
6929 * error.h: adjust scm_syserror_msg prototype.
6930 * error.c (scm_syserror_msg): take an extra argument for errno.
6931 Using the global value didn't always work, since it could be
6932 reset by procedure calls in the message or args arguments.
6934 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
6935 I don't understand why the check was there (and what about the
6938 * strop.c (scm_string_copy): allow shared substrings to be copied.
6940 * unif.h: corresponding change to prototypes.
6941 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
6942 recognize two new optional arguments: offset and length. Allow
6943 the port argument to be an integer (file descriptor, for scsh).
6944 Include <unistd.h> for "read" prototype.
6946 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6948 * socket.c: don't include filesys.h.
6950 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6952 * Makefile.am: add AWK=@AWK@ (?)
6954 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6956 Add a rule to generate errnos.c from errnos.
6957 * error.c (scm_init_error): include errnos.c.
6958 * errnos_cnvt.awk: new file, converts the list of errno codes to
6960 * errnos_get.c: new file.
6961 * errnos.default: new file, contains errnos to try if they can't
6962 be extracted from errno.h.
6963 * configure.in: if using GCC, try and extract errno codes from
6967 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6969 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
6970 * Makefile.am: Made libguile into a libtool library.
6971 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
6972 Set libtool_libs to indicate that libguile is a libtool library.
6973 See guile/ChangeLog for details.
6974 * .cvsignore: ignore "*.lo", the libtool library objects.
6976 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6978 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
6979 use htons in getservbyport argument.
6981 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6983 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
6984 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
6987 * objprop.c (scm_object_property): No need to take the CDR of the
6988 value returned by scm_object_properties, since Aug 20 change.
6990 * configure.in: When checking for struct linger, #include
6991 <sys/types.h> as well as <sys/socket.h>. I've never known
6992 <sys/types.h> to cause any portability problems, and Solaris's
6993 <sys/socket.h> needs it.
6994 * configure: Rebuilt.
6996 I think the Sun compiler has chosen a perverse way to interpret
6997 ANSI declarations combined with K&R definitions. We'll
6998 appease it a little bit. But when it invades France, we fight.
6999 * print.c (scm_iprlist): Change 'tlr' argument to an int.
7000 * print.h (scm_iprlist): Here too.
7001 * numbers.c (scm_divbigdig): Change definition to match
7002 declaration in numbers.h.
7003 * unif.c (scm_makflo): Change definition to match declaration in
7006 * init.c (scm_boot_guile): Don't return the value of
7007 scm_boot_guile_1. This function doesn't return a value;
7008 scm_boot_guile_1 doesn't return a value (or return at all).
7010 * eval.c (unmemocopy): Add a semicolon to appease the Sun
7013 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
7014 compile. I have a feeling this function is a bad idea anyway ---
7015 one should always test for features, not systems.
7017 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
7018 semicolons. Only pure luck kept this from being noticed earlier.
7020 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
7022 * socket.c (scm_recvfrom): Added missing semicolon.
7024 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
7026 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
7027 the buffer and start and end positions for scsh networking
7030 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
7032 * configure.in: Revert previous change to this file; the problem
7033 is due to transient automake weirdness.
7034 * configure: Rebuilt.
7036 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
7037 PLUGIN/guile.libs. configure generates the latter from the former.
7038 * Makefile.in: Rebuilt.
7040 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
7041 need this if we install scripts, like guile-snarf.
7042 * configure: Rebuilt.
7044 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
7046 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
7048 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
7050 * socket.c (scm_addr_vector): fix faulty scm_listify.
7052 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
7054 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
7055 style block comment is no longer considered an error.
7057 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
7059 * PLUGIN/guile.libs.in: New file.
7060 * PLUGIN/guile.libs: Removed from repository.
7061 * configure.in: Create PLUGIN/guile.libs from
7062 PLUGIN/guile.libs.in. This is for including additonal libraries
7063 needed for dynamic linking.
7064 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
7065 instead of PLUGIN/guile.libs.
7067 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
7069 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
7071 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
7072 occurrences of the given element from the list, not just the
7073 first. This is how the Emacs Lisp functions behave, how the
7074 analogous Common Lisp functions behave, and (I believe) how the
7075 older Maclisp functions worked. I realize that this change may
7076 break code, but it seemed better to break it before the Guile
7079 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
7080 Their prototypes were already present in gc.h, but they weren't
7082 (scm_init_storage): Initialize scm_protects.
7083 * root.c (scm_protects): New element of scm_sys_protects.
7085 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
7087 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
7089 * libguile.h: Added #include "libguile/net_db.h".
7091 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
7092 30 change. That file is only meant for communication between the
7093 configuration process and load.c. If code linked against libguile
7094 wants to get at the paths mentioned in libpath.h, it can call
7095 functions declared in load.h.
7097 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7099 * libguile.h: Removed #include "libguile/fdsocket.h"
7101 * net_db.c: Added #include <sys/socket.h>.
7103 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
7105 * filesys.c (scm_input_waiting_p): use select in preference to
7106 FIONREAD, since the latter doesn't detect EOF.
7107 Throw error if neither select nor FIONREAD available.
7109 * socket.c (scm_connect): take a port, not a fd object.
7110 (scm_fill_sockaddr): throw an error if fam is not recognised.
7111 (scm_bind): use scm_fill_sockaddr.
7112 (scm_listen): take a port, not a fd object.
7113 (scm_accept): take and return a port. return #f in the car if
7114 address can't be got
7115 (scm_sock_fd_to_port): new procedure.
7116 (scm_socket): use scm_sock_fd_to_port.
7117 (scm_addr_vector): throw error if unrecognised address type.
7118 take an extra argument with the calling procedure name.
7119 (scm_getsockname): take a port. return #f if address can't be got.
7120 (scm_getpeername): take a port. return #f if address can't be got.
7121 (scm_recvfrom): take a port. return #f for address component if can't
7123 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
7124 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
7126 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
7128 * throw.c (scm_internal_catch): Make body funcs and handler funcs
7129 use separate data pointers, to allow them to be designed
7130 independently and reused.
7131 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
7132 Renamed from catch_body, catch_handler, and uncaught_throw; made
7134 (struct scm_catch_body_data): Renamed from catch_body_data; moved
7136 (scm_catch): Use the above.
7137 (scm_throw): Don't bother printing a message for an uncaught
7138 throw; we establish a default handler in init.
7139 * throw.h (scm_internal_catch): Prototype updated.
7140 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
7142 (struct scm_body_thunk_data): New structure, used as data
7143 argument to scm_body_thunk.
7144 * init.c (struct main_func_closure): New structure, packaging up
7145 the data to pass to the user's main function.
7146 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
7147 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
7148 scm_internal_catch to establish a catch-all handler, using
7149 scm_handle_by_message. This replaces the special-case code in
7151 (invoke_main_func): Body function for scm_internal_catch; invoke
7152 the user's main function, using the main_func_closure pointer to
7153 decide what to pass it.
7154 * root.c (struct cwdr_body_data): Remove handler_proc member.
7155 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
7156 (cwdr_handler): Removed.
7158 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
7160 * socket.h (SCM_P): update bind prototype.
7161 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
7162 include "feature.h".
7163 (scm_socket): return a port, not a file descriptor object.
7164 include "fports.h" and <unistd.h>
7165 (scm_bind): take a port, not a file descriptor object.
7166 take an extra argument for address args.
7168 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
7169 INADDR_NONE, INADDR_LOOPBACK.
7171 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
7173 * init.c: include net_db.h and not fdsocket.h.
7174 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
7176 * Makefile.am: corresponding changes.
7177 * socket.h: renamed from fdsocket.h, fix names.
7178 * net_db.h: renamed from socket.h, fix names.
7179 * socket.c: renamed from fdsocket.c.
7180 remove _sys from procedure names.
7181 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
7182 add "socket" to features list.
7183 * net_db.c: renamed from socket.c.
7184 remove _sys from procedure names.
7185 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
7186 add "net-db" to features list.
7187 include "net_db.h". don't include <sys/socket.h> or
7190 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7192 * tags.h (scm_tags): Removed comma at end of last enumerator.
7194 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
7196 Don't use GCC extensions to allocate space for debugging frames.
7197 (Here he goes again! Why do we put up with this?!)
7198 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
7199 an scm_debug_info structure, not an in-line array of them. Add
7200 'info' member, to say how many vect elements we've used, for eval
7202 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
7203 a new variable debug_info_end to mark the end of vect, instead of
7204 the address of the 'info' pointer itself.
7205 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
7206 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
7207 (SCM_APPLY): Explicitly allocate space for debug.vect.
7208 * debug.c (scm_m_start_stack): Same, for vframe.vect.
7209 * stacks.c: Adjusted for new debug frame structure.
7210 (RELOC_INFO, RELOC_FRAME): New macros.
7211 (stack_depth, read_frames): Use them, and new scm_debug_frame
7212 element 'info', instead of magically knowing that eval frames have
7213 an info pointer sitting after vect.
7214 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
7216 (scm_init_stacks): Formatting tweaks.
7218 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
7220 Give GCC more control flow information, so it can be sure that
7221 variables aren't used uninitialized.
7222 * error.h (scm_error, scm_syserror, scm_syserror_msg,
7223 scm_sysmissing, scm_num_overflow, scm_out_of_range,
7224 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
7225 scm_misc_error): Tell GCC that these functions never return.
7226 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
7227 out the field type, call abort if SCM_ASSERT returns, to placate
7229 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
7230 scm_wta ever returns. We can't handle this case anyway, and this
7231 gives the optimizer more information.
7232 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
7233 scm_wta ever returns.
7235 In some cases, the code is fine, but GCC isn't smart enough to
7236 figure that out; this usually happens when one variable is only
7237 initialized and used when a particular condition holds true, and
7238 we know that condition will never change within a given invocation
7239 of the function. In this case, we simply initialize the variables
7240 to placate the compiler, hopefully to a value which will cause a
7241 crash if it is ever actually used.
7242 * print.c (scm_iprin1): Initialize mw_pos.
7243 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
7244 * throw.c (scm_ithrow): Initialize dynpair.
7245 * unif.c (scm_uniform_vector_ref): Initialize cra.
7246 * struct.c (init_struct): Initialize prot.
7247 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
7249 * strports.c (scm_eval_0str): Don't return uninitialized garbage
7250 if EXPR contains no expressions.
7252 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
7254 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
7255 cause an infinite loop (???). So much for the algebraic
7256 equivalency of variable-sized arrays and alloca...
7258 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
7260 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
7261 a SCM boolean, not a C boolean.
7263 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
7265 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
7266 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
7267 rules for raising scm_mtrigger. Previously, unfortunate but not
7268 unlikely circumstances could result in almost constant invokation
7269 of the gc. Now, this situations should be less likely, but they
7270 are not prevented completely.
7272 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
7274 * numbers.c (scm_fuck): Procedure removed; looks like old test
7276 * numbers.h: Prototype removed.
7278 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
7280 * debug.h (scm_debug_frame): Change `vect' member from an in-line
7281 array to a pointer, to match my Nov 21 change in eval.c.
7283 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7285 * libguile.h: Added #include "libguile/backtrace.h", #include
7286 "libguile/stacks.h".
7288 * strings.c (scm_string scm_make_string scm_string_ref
7289 scm_string_set_x scm_string_equal_p scm_string_append):
7290 Bugfix according to scm patch from Aubrey Jaffer:
7291 Corrected long-standing
7292 (not (eqv? (integer->char 128)
7293 (string-ref (make-string 1 (integer->char 128)) 0)))
7294 bug found by John Kozak <jk@noontide.demon.co.uk>.
7296 * strports.c, strports.h: Make scm_eval_0str return the value of
7297 the last expression evaluated (previously, it returned void).
7299 * strports.c, strports.h: New function: scm_read_0str. Does what
7302 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7304 * simpos.c (scm_getenv): return #f if string can't be found in the
7305 environment instead of throwing an exception, for compatibility
7306 with numerous other systems.
7308 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
7310 * Makefile.am (.c.x): Use guile-snarf.
7311 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
7313 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
7315 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
7317 * backtrace.c (scm_display_error_message): Made non-static, and
7318 renamed from display_error_message.
7319 * backtrace.h (scm_display_error_message): Added extern decl.
7320 * throw.c (uncaught_throw): Use it to display the error message.
7322 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
7324 * inet_aton.c: Use #if 0, not #ifdef 0.
7326 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
7328 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
7329 to convert the returned value.
7330 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
7331 the offset argument.
7333 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
7335 Add new interface to catch/throw, usable from C as well as
7337 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
7338 (scm_internal_catch): New function, replaces...
7339 (scm_catch_apply): Deleted.
7340 * throw.c (scm_catch_apply): Deleted; replaced with a more general
7341 mechanism which is a bit more code, but can be used nicely from C
7342 and implement the Scheme semantics as well.
7343 (scm_internal_catch): This is the replacement; it's named after
7344 the analogous function in Emacs.
7345 (scm_catch): Reimplemented in terms of the above.
7346 (struct catch_body_data, catch_body, catch_handler): New
7347 functions, used by scm_catch.
7348 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
7349 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
7350 support for new cwdr.
7352 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
7355 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
7357 * acconfig.h: Added DYNAMIC_LINKING symbol.
7358 * configure.in: Add option and checks for dynamic linking.
7359 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
7360 dynl.h: New files for dynamic linking support.
7361 * Makefile.am (libguile_a_SOURCES):
7363 (modinclude_HEADERS): Added "dynl.h".
7364 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
7366 * init.c (scm_boot_guile_1): Call
7367 scm_init_dynamic_linking to initialize dynamic linking support.
7369 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
7371 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
7372 (as we Schemers say). It needs to be global, so that I can tweak
7373 it for the proper operation of unexec.
7374 (scm_boot_guile_1_live): New variable, see above.
7376 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
7378 * guile-snarf.sh: Removed.
7379 * PLUGIN/guile.libs: Added dependency for -lm.
7380 * acinclude.m4: Renamed from aclocal.m4.
7381 * PLUGIN/greet: Removed.
7382 * Makefile.am, aclocal.m4: New files.
7383 * configure.in: Updated for Automake.
7385 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
7387 * eval.c (scm_definedp): Use top_level_lookup_closure_var
7388 and not top_level_lookup_thunk_var.
7390 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
7392 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
7394 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
7396 * eval.c (scm_definedp): Incompatibly changed to be a builtin
7397 Scheme function, instead of syntax. Single argument is now a
7400 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7402 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
7403 scm_ra_divide): Properly terminate statements passed as arguments
7404 to IVDEP macros. (Thanks to Bernard Urban.)
7406 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
7407 with non-constant sizes. (Thanks to Bernard Urban.)
7409 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
7411 It's an "eval closure", not an "eval thunk." A thunk is a
7412 function of no arguments.
7413 * root.h (struct scm_root_state): Renamed
7414 top_level_lookup_closure_var from top_level_lookup_thunk_var.
7415 (scm_top_level_lookup_closure_var): Renamed from
7416 scm_top_level_lookup_thunk_var.
7417 * root.c (mark_root): Uses changed.
7418 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
7419 * init.c (scm_start_stack): Uses changed.
7420 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
7421 Change scheme-visible name to *top-level-lookup-closure* from
7422 *top-level-lookup-thunk*.
7424 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
7426 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
7427 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
7429 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
7431 * gc.c (struct scm_heap_seg_data): Doc fixes.
7433 * gc.c (scm_gc_sweep): Empty all segments' freelists before
7434 sweeping. Then, prepend each segment's free cells to its
7435 freelist, rather than wiping out the old value. (Thanks to Marius
7438 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
7439 scm_check_freelist, scm_debug_newcell): New functions and
7440 variables, for debugging freelist problems.
7441 * pairs.h (SCM_NEWCELL): New debugging version added.
7442 * gc.h (scm_debug_newcell): Added extern declaration, used by
7443 debugging version of SCM_NEWCELL.
7445 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7447 On some systems <libc.h> conflicts with <unistd.h>, and should not
7448 be #included at all.
7449 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
7450 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
7451 * configure.in: Call it.
7452 * posix.c, filesys.c: Use its results to decide whether or not to
7454 * configure, scmconfig.h.in: Rebuilt with autoconf and
7457 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7459 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
7460 pointer to the stdio stream before calling scm_setbuf0, so the
7461 latter will be able to retrieve it. I'm surprised this didn't
7462 segfault earlier. (Thanks to Christopher Lee.)
7464 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7466 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
7469 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7471 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
7472 number of stack narrowing specifier pairs. The first specifier in
7473 a pair controls inner border, the second the outer border. A
7474 number means cut that number of frames, a procedure object means
7475 cut until that object is found in operator position in a frame.
7477 * root.c (cwdr): Bugfix.
7479 * read.c: Recording of positions disabled by default.
7481 * procs.c (scm_closure_p): New function.
7483 * posix.c (scm_tmpnam): New function.
7485 * load.c: Added #include "throw.h".
7486 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
7489 * load.c, load.h (scm_read_and_eval_x): New function.
7491 * eval.c: Renamed debug option "deval" to "debug".
7493 (scm_eval_x): `eval!' is no longer accessible from the scheme
7494 level. Motivation: We can't allow operations which introduce
7495 glocs into the scheme level. Guile's type system can't handle
7496 these as data. Use `eval' or `read-and-eval!' as replacement.
7498 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
7499 SCM_CONSP since this is a macro!; Set vframe.prev to
7500 scm_last_debug_frame instead of 0. In this way we can look
7501 "above" the virtual start stack frame if we wish.
7502 (scm_debug_hang): New function: Useful for debugging Guile in
7503 certain tricky situations. Will probably be removed later...
7505 * debug.h: Changed semantics of debug option "backtrace". This
7506 option now only indicates whether we want automatic backtrace at
7509 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7511 * ports.c: #include "filesys.h"
7512 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
7514 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
7515 Motivation: This is system specific code which is related to file
7516 I/O. It also may use select. Added code by Gary Houston to
7517 detect presence of character in stdio buffers.
7519 * libguile.h: #include "libguile/libpath.h"
7521 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
7522 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
7523 SCM_SITE_DIR; Install libpath.h among the other include files.
7525 * load.c, load.h (scm_sys_package_data_dir): New function.
7527 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7529 * stacks.h: Bugfix: Don't use tail-array length field as stack
7530 length field! This screwed GC.
7532 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7534 * _scm.h: Added #ifndef around definition of macros min and max.
7536 * __scm.h: Added hooks for threads to plugin to in ints protection
7537 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
7538 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
7539 the main code in these macros duplicated and spread over multiple
7540 files. Renamed SCM_THREADS_SWITCHING_CODE ->
7541 SCM_THREAD_SWITCHING_CODE.
7543 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
7545 * snarf.h: New file.
7546 * guile-snarf.sh: New file.
7547 * Makefile.in (inner_h_files): Added snarf.h
7548 (ancillary, install, uninstall, distclean): Added actions for
7550 (.c.x): Use guile-snarf.
7551 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
7552 (gen_c_files): Note that these depend on guile-snarf.
7553 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
7554 now in "snarf.h". Added #include "snarf.h" to get them.
7555 * libguile.h: Added #include "snarf.h".
7556 (Patches applied and tweaked by Jim Blandy.)
7558 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7560 * socket.c: Use K&R style declaration for 'close'; the GNU coding
7561 standards suggest against providing prototypes for system
7562 functions. Thanks to Greg Troxel.
7564 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
7566 * strports.c (scm_eval_0str): New function.
7567 #include "read.h", to get prototype for scm_read.
7568 * Makefile.in (strports.o): Update dependencies.
7569 * strports.h: New prototype.
7571 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
7572 scheme name from "int?" to "integer?". It seems to do the job.
7573 * numbers.h: Rename prototype too.
7574 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
7577 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
7578 scm_num_eq_p): Rename these according to R4RS conventions: call
7579 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
7580 to making libguile R4RS compliant without ice-9...
7582 * load.c (scm_sys_search_load_path): Search for files under all
7583 extensions listed in the %load-extensions variable. If FILENAME
7584 is absolute, return it unchanged, without searching the load path.
7585 (scm_loc_load_extensions): New variable, pointing to
7586 %load-extensions' value cell.
7587 (scm_init_load): Initialize it, and the value it points to.
7588 (scm_primitive_load_path): Improve error reporting.
7590 * load.c (scm_loc_load_hook): New variable, pointing to value cell
7591 of new Scheme variable %load-hook.
7592 (scm_primitive_load): Apply %load-hook to filename.
7594 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
7596 * configure.in: add tests for figuring out whether buffered data
7597 is available in a FILE structure, which is needed by char-ready.
7599 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
7602 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
7603 exceptions using misc_error instead of syserror. It seems a bit
7604 odd to throw an exception if a string can't be found in the
7605 environment, but it's consistent with open-file, stat etc.
7606 (simpos.h): remove sys_ from getenv.
7608 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
7609 occurs, throw an error instead of returning errno. Return value
7611 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
7613 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
7615 * filesys.c (scm_stat2scm): derive file type and permissions from
7616 the stat mode and append them to the returned vector.
7617 There isn't much overhead in doing this and it avoids the need to
7618 work with S_IRUSR et al. in Scheme.
7619 Define symbols scm_sym_regular etc.
7620 (scm_init_filesys): don't intern S_IRUSR etc.
7622 * load.c: change s_try_load and s_try_load_path to s_primitive_load
7623 and s_primitive_load_path.
7625 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
7627 * error.h: don't declare error symbols. prototype for scm_misc_error.
7629 * stackchk.c (scm_stack_overflow_key): defined here instead of in
7632 * error.c: use SCM_SYMBOL to set up error keys.
7633 scm_misc_error: new procedure.
7635 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
7637 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
7638 between `#!' and `!#' is ignored.
7639 (skip_scsh_block_comment): New function.
7641 * feature.c (scm_set_program_arguments): New argument, FIRST.
7642 * feature.h: Update prototype.
7643 * init.c (scm_boot_guile_1): Pass new argument to
7644 scm_set_program_arguments.
7646 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
7648 * init.c (scm_start_stack): Don't initialize scm_progargs here.
7649 (scm_boot_guile): Call scm_set_program_arguments here, later than
7650 the old initialization.
7652 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
7653 initialization procedure.
7654 - Delete in, out, err arguments; there are other perfectly good
7655 ways to override these when desired.
7656 - Delete result argument; this function shouldn't ever return.
7657 - Rename init_func argument to main_func, for less confusion.
7658 - Delete boot_cmd argument; main_func is more general.
7659 -Add 'closure' argument, to help people pass data to main_func
7660 without resorting to global variables.
7661 - Abort if reentered; don't bother returning an error code.
7662 - Call scm_init_standard_ports to set up the default/current
7663 standard ports; no need to pass them to scm_start_stack.
7664 - Remove code to evaluate the boot_cmd, and start the repl; let
7665 the user do something like that in main_func if they want.
7666 - Remove code to package up a return value; main_func can do any
7668 - Call exit (0), instead of returning.
7669 (scm_start_stack): Don't initialize the I/O ports here; that's
7670 weird. Delete in, out, err arguments. Move guts to
7671 scm_init_standard_ports, scm_stdio_to_port.
7672 (scm_init_standard_ports): New function, to set up current and
7673 default standard ports.
7674 (scm_start_stack, scm_restart_stack): Make these static.
7675 * init.h (scm_boot_guile): Adjust declaration.
7676 (scm_start_stack, scm_restart_stack): Remove externally
7677 visible declarations for these.
7678 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
7680 * fports.c (scm_stdio_to_port): New function. Its guts used to be
7681 written out several times in scm_start_stack.
7682 * fports.h: New declaration for the above.
7684 * feature.c (scm_set_program_arguments): New function.
7685 * feature.h: New declaration for the above.
7687 * ports.c: Formatting tweak.
7689 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
7691 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
7692 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
7693 for obtaining the address of a car or cdr field. Motivation:
7694 &SCM_CXR make assumptions about the internal structure of the
7697 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
7698 Motivation: see SCM_CXRLOC.
7700 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
7701 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
7702 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
7703 Motivation: Safer use. Some other macros are defined in terms of
7704 these operations. If these are defined using the SCM_SETCXR
7705 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
7706 to inefficiency and an <e1> with side-effects could potentially
7707 break. Also, these particular operations are heavily utilized in
7708 the garbage collector. In unoptimized code there will be a
7711 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
7712 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
7713 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
7714 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
7715 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
7716 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
7717 vports.c: Cleaned up use of pairs: Don't make any special
7718 assumptions about the internal structure of selectors and
7719 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
7720 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
7721 (Among other things, this change makes it easier to build Guile
7722 with certain compilers which have problems with casted lvalues.)
7724 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7726 * stacks.c: Improve selection of relevant stack frames when making
7727 a stack object. Introduce one level of indirection in the stack
7728 object to make it possible to "narrow" to a certain region of the
7729 stack. This facilitates making use of more clever algorithms (not
7730 implemented) for selecting relevant frames and gives a cleaner
7731 design since selection of frames can be done independently of
7732 extraction of frames from the real stack.
7733 (scm_stack_id): Also take #t as argument which means look at
7736 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
7737 Turn n_tail into an integer directly representing current number
7738 of frames in stack. Add field tail.
7740 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
7742 * debug.c (scm_make_memoized): Made it available at scheme level.
7743 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
7744 SCM_NIMP before applying heavier predicates in argument checking.
7745 (scm_local_eval): Also take memoized object as argument.
7747 * backtrace.c (scm_display_error): Just a safety measure: Stacks
7748 aren't created with zero length, but should such a strange
7749 creature suddenly turn up...
7751 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
7753 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
7754 `del', for the sake of C++ compilers. (Patch applied by JimB.)
7756 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
7758 * variable.c (scm_make_variable): Make the name hint optional, as
7760 (anonymous_variable_sym): Renamed from variable_sym. All uses
7763 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
7764 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
7765 of scm_primitive_load_path was also changed to
7766 "primitive-load-path", from "%try-load-path". Callers changed.
7767 We'd like to respect the convention that a function named
7768 "try-mumble" should behave just like the function called "mumble",
7769 but return #f instead of signalling some error.
7770 * load.h: Rename prototypes.
7772 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7774 * print.c (make_print_state, grow_print_state), print.h: Modified
7775 the print state representation: Don't use a tail array for
7776 recording of circular references. Resizing of the print state
7777 structure invalidates the print state pointer. To avoid passing
7778 around an indirect print state reference to all printing
7779 functions, we instead let the print state reference a resizable
7782 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7784 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
7785 Don't crash when passed an improper list terminated by a
7786 non-immediate value.
7788 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
7790 Allocate data for structures on an eight-byte boundary, as
7791 required by the tagging system.
7792 * struct.c (alloc_struct): New function.
7793 (scm_make_struct, scm_make_vtable_vtable): Call it.
7794 * struct.h (scm_struct_n_extra_words): Bump to 3.
7795 (scm_struct_i_ptr): New "field".
7796 * gc.c (scm_gc_sweep): When we need to free the data, use the
7797 information stored by alloc_struct to find the beginning of the
7798 block allocated to the structure, so we can free it.
7800 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7802 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
7805 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
7806 (scm_debug_info): New member: id.
7808 * stacks.c: Stacks are now represented as structs; Stacks have an
7809 id given to them by `start-stack'.
7810 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
7812 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
7813 Changed stack representation.
7815 * debug.c (scm_procedure_name): Try procedure property `name' for
7816 compiled closures aswell.
7818 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
7820 * eval.c: scm_i_name moved to gsubr.c
7821 (scm_m_define): Record names of all kinds of procedure
7822 objects. (Earlier, only closures were recorded.)
7824 * procprop.h: Added declaration of scm_i_name.
7826 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
7827 (scm_make_gsubr): Record names of compiled closures.
7829 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7831 * debug.c, debug.h: Removed obsolete code.
7833 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
7834 stacks.c: Renamed regs --> scm_contregs.
7836 * print.c (scm_free_print_state): Cleanup print state before
7837 returning it to pool. It is better to do it here than in
7838 scm_prin1 since scm_prin1 is called often.
7840 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
7841 s_set_source_property_x): Check that first argument is a pair or a
7844 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
7845 scm_i_line, scm_i_column and scm_i_breakpoint global.
7847 * init.c: Added #include "backtrace.h" and #include "stacks.h".
7848 (scm_boot_guile_1): Added calls to scm_init_backtrace and
7851 * debug.h: Added debug object smob declaration and macro
7854 * configure.in: Build with backtrace.o and stacks.o if debug
7857 * Makefile.in: Added entries for new files: backtrace.c,
7858 backtrace.h, stacks.c and stacks.h.
7860 * symbols.c (scm_sym2ovcell): Fixed documentation.
7862 * _scm.h (min, max): Added.
7864 * async.c: Moved `min' macro to _scm.h.
7866 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
7867 SCM_BACKTRACE_INDENT.
7869 * eval.c: Added new debug options `maxdepth' and `indent'.
7871 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
7873 * print.h: Added selector SCM_PRINT_STATE.
7875 * print.c: New functions: scm_make_print_state,
7876 scm_free_print_state.
7878 * print.h: Added declarations for scm_make_print_state,
7879 scm_free_print_state.
7881 * debug.c (scm_m_start_stack): New acro.
7883 * debug.h: Small cleanup.
7885 * init.c (scm_boot_guile_1): Moved scm_init_debug below

7910 declare functions with prototypes. (Patch thanks to Marius
7913 More prototype-related changes from Marius Vollmer:
7914 * gdb_interface.h: Wrapped header file in #ifdef/#endif
7915 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
7916 * ports.h (ptobfuns): Added prototypes. This means some casting in
7918 * fports.c: Added casts for initializations, since the functions
7919 are defined to take FILE * as their stream argument, not SCM.
7920 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
7921 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
7922 to `char *str_data' to conform to prototype.
7924 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7926 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
7928 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
7930 * stime.c, stime.h: use SCM_P method.
7932 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7934 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
7935 be given at least two arguments. Insist that lst's last element
7936 be a list, but don't make any requirements of its predecessors.
7938 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7940 * eval.c (scm_nconc2last): Revert last change; there seems to be
7941 other stuff going on here.
7943 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7945 * eval.c (scm_nconc2last): Make sure that each element of lst
7946 (which is a list of argument lists, except for the tail) is a
7947 proper list, i.e., finite and terminated by '().
7949 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7951 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7954 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7955 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7958 * vectors.c (scm_make_vector): Fill vectors with the undefined
7959 value, to help make Guile Scheme code more portable to other
7962 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7963 * symbols.h, tags.h: Doc fixes.
7965 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
7967 * async.c (scm_take_signal): Doc fixes.
7969 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
7971 * numbers.c (scm_divbigint): When the remainder is zero, we don't
7972 want to subtract it from the modulus; we just want to leave it
7975 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
7977 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
7980 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
7982 * throw.c (scm_catch_apply): Finished implementation of
7985 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7987 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
7989 (scm_init_filesys): set "i/o-extensions" feature.
7992 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
7994 * Makefile.in (root.o): Correct dependencies.
7996 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
7998 * Makefile.in: Added dependency entry for root.o.
8000 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
8001 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
8003 * init.c (scm_start_stack): Set initial root continuation number
8006 * procs.c: New function: scm_thunk_p.
8008 * procs.h: Added declarations of scm_thunk_p.
8010 * root.c: Renamed `call-with-new-root' -->
8011 `call-with-dynamic-root'.
8012 (cwdr): Removed allocation of new root state. This should be done
8013 separately by use of scm_make_root.
8014 (scm_apply_with_dynamic_root): New function: Does what it
8015 sounds like. Needed when spawning threads.
8017 * root.h: Added member last_debug_frame to root state.
8018 Added #include "libguile/debug.h"
8020 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
8021 arguments. The motivation is that code in root.c needs catch
8022 functionality, and we want to avoid code duplication.
8023 New functions: scm_catch, scm_lazy_catch. These are wrappers for
8024 scm_catch_apply. scm_lazy_catch is intended to introduce catch
8025 handlers that run without popping the stack into the dynwind
8028 * throw.h: Added prototypes for scm_catch_apply and
8031 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8033 * root.h (scm_root, scm_set_root): Decouple thread support details
8034 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
8035 SCM_SET_THREAD_LOCAL_DATA.
8037 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
8038 and tortoise scanning loop.
8040 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
8042 * Makefile.in: Rebuild dependencies.
8044 * libguile.h: #include "libguile/print.h" before "smob.h", since
8045 the latter uses the print_state structure.
8047 * throw.c (scm_ithrow): Use the correct variable when checking to
8048 see if a given element of scm_dynwinds is a valid catch.
8050 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
8051 structure, abort; don't just silently ignore the garbage.
8053 * _scm.h: #include "print.h" here, since it seems to be used just
8055 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
8056 strports.c, unif.h: Don't #include "print.h".
8058 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8060 * feature.h (scm_loc_features): Removed external declaration.
8061 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
8063 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8065 * feature.c (scm_init_feature): Added threads feature (needs to be
8066 initialized here, since features doesn't exist when
8067 scm_init_threads is called).
8069 * libguile.h: Added #include "libguile/../threads/threads.h".
8070 (This is a kludge to get thread support working. This should be
8073 * configure.in, acconfig.h: Added flags for thread support.
8075 * scmsigs.c: Define `signal' to be `pthread_signal' if using
8078 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
8079 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
8082 * _scm.h: Added conditional #include "threads.h"
8084 * __scm.h (SCM_ASYNC_TICK): Added call to macro
8085 SCM_THREADS_SWITCHING_CODE.
8087 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
8088 allocate the basic dynamic root object.
8089 (scm_boot_guile): Added call to scm_init_root.
8091 * root.c, root.h: Added root smob.
8092 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
8093 functions: Implements dynamic roots mostly according to spec in
8094 SCM manual. Main difference is that the second argument is a
8095 throw handler rather than an error "thunk".
8097 * root.h: Added declaration of scm_init_root.
8099 * root.c: Added #include "genio.h", #include "smob.h", #include
8100 "pairs.h", #include "throw.h", #include "dynwind.h", #include
8102 (scm_init_root): Added #include "root.x".
8104 * throw.c: Added #include "stackchk.h"
8105 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
8106 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
8107 can be used in scm_call_with_new_root; Added reenabling of stack
8108 checking when catching a throw.
8110 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
8112 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
8114 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
8115 element is not found, as per R4RS.
8117 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
8119 * list.c: Doc fixes throughout.
8121 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
8123 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
8124 declare the char * to be const. Avoids a warning in rgx.c.
8126 * ports.h: spelling fix.
8128 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
8131 * load.c (scm_sys_try_load_path): throw an error if file not found
8132 (like it says it in NEWS).
8134 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
8136 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
8137 PROPS slot to '(), not #f; it's an empty alist.
8139 * throw.h, throw.c: Use SCM_P instead of #if hair.
8141 Remove special support for uncaught throws; see throw.c for
8143 * throw.c (uncaught_throw): New function.
8144 (scm_ithrow): Call uncaught_throw if we don't find a throw
8145 target; don't mess with scm_bad_throw_vcell.
8146 (scm_bad_throw_vcell): Variable deleted.
8147 (scm_init_throw): Don't initialize it.
8149 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
8152 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
8154 * numbers.c (scm_istr2int): If the number is short (as most
8155 numbers are), just call scm_small_istr2int to deal with it.
8156 (scm_small_istr2int): New function, created by un-#ifdefing the
8157 non-bignum version of scm_istr2int and renaming it.
8159 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
8161 * load.c (scm_sys_try_load): don't check whether value returned
8162 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
8163 Change the Scheme name from %try-load to primitive-load.
8165 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
8166 Can avoid passing a message, allowing it to be derived in the
8167 error handler (e.g., if we want to throw to the key both from
8170 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
8172 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
8173 references now have a new appearance which is more compact and
8174 also gives a clue about what the target of the reference is.
8175 By setting parameters in the print state, more fancy printing can
8176 be achieved. This is used by the (not yet commited) backtrace
8179 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
8181 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
8184 * print.c: Added #include "struct.h". Removed function
8187 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
8188 scm_iprin1. Removed prototype for scm_prlist.
8190 * arbiters.c (prinarb),
8191 async.c (print_async),
8192 debug.c (prindebugobj, prinmemoized),
8193 eval.c (prinprom, prinmacro),
8194 filesys.c (scm_fd_print, scm_dir_print),
8196 mallocs.c (prinmalloc),
8197 numbers.c, numbers.h (scm_floprint, scm_bigprint),
8198 smob.h (scm_smobfuns),
8199 srcprop.c (prinsrcprops),
8201 unif.c, unif.h (scm_raprin1, rapr1),
8202 variable.c (prin_var): Changed argument `int writing' to
8203 `scm_print_state *pstate'.
8205 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
8206 that it will be called before scm_init_print.
8208 * print.c (scm_prin1): Print states are now allocated when calling
8209 scm_prin1 and then passed around to all printing functions as an
8210 argument. A cache `print_state_pool' enables reuse of print
8212 (scm_make_print_state): New function.
8213 (scm_iprin1): Adaption to print states.
8214 (scm_iprlist): An initial "hare and tortoise" scan brings down
8215 time complexity to O (depth * N). (Better time complexity will be
8216 achieved when the printing code is completely rewritten.)
8218 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
8220 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
8221 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
8222 it gets done whether or not the cache variable has a value.
8224 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8226 Distinguish #f and ().
8227 * __scm.h: #undef SICP.
8228 * pairs.h (SCM_EOL): Delete this definition, equating it with
8230 * tags.h (SCM_EOL): Give it a new definition here; I think I found
8231 the value it used to have. Doc fixes, too.
8233 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
8235 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
8236 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
8237 Lord's implementation of structs, allowing for tail arrays as
8238 described in the manual. Also fixed some bugs. (Both the interface
8239 and the implementation should be improved.)
8241 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
8243 * print.c, print.h: Closures now print like #<procedure foo (x)>.
8244 People who whish to see the source can do `(print-enable 'source)'.
8245 Removed #ifdef DEBUG_EXTENSIONS.
8247 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
8249 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
8250 integer (assuming for now accepting an integer is a good thing).
8252 * error.c, fports.c: replace use of %S in lgh_error args with %s.
8253 %S will be used instead for write'ing arguments.
8255 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
8256 asserts. fix a few other asserts.
8257 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
8258 scm_uniform_vector_ref, scm_array_set_x,
8259 scm_dimensions_to_unform_array): change args in
8260 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
8261 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
8262 scm_substring_fill_x): likewise.
8263 gsubr.c (scm_gsubr_apply): likewise.
8264 eval.c (SCM_APPLY): likewise.
8266 * eval.c (4 places): replace scm_everr with lgh_error or
8269 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
8270 scm_memory_error): new procedures.
8271 scm_everr: deleted. can use scm_wta, dropping first two args.
8272 scm_error: convert NULL subr to SCM_BOOL_F.
8274 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
8277 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
8280 * error.c, error.h: new error keys: scm_arg_type_key,
8281 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
8283 scm_wta: reimplement using lgh_error instead of scm_everr.
8285 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
8287 * gdbint.c: scm_lread now has one more argument.
8289 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
8290 scm_port_\1; Added mutator scm_set_port_filename_x (used when
8291 loading source from non-file ports, which, e. g., happens when
8292 using the Emacs interface).
8294 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
8297 * read.c: Added code for recording of positions of source code
8298 expressions; New functions: recsexpr, scm_lreadrecparen;
8299 _scm_make_srcprops --> scm_make_srcprops
8300 (scm_flush_ws): Removed updating of positions counters. This work
8301 is already done by scm_gen_getc
8303 * read.h: Added prototype for scm_lreadrecparen
8305 * print.c: Added #include "alist.h"
8307 * eval.c: Added #include "hash.h"
8309 * eq.c: Added #include "ramap.h"
8311 * options.c: Documentation fixes.
8313 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
8314 (scm_init_srcprop): Adjusted size of initial source-whash. Name
8315 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
8316 --> scm_make_srcprops
8318 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
8319 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
8320 function calls in the definition of the whash access macros.
8322 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
8324 * init.c (scm_boot_guile): Add level of indirection to
8325 scm_boot_guile_1() to ensure that stack base pointer is properly
8326 initialized. There was no guarantee that variable i was the
8327 highest/lowest variable on stack (i.e. the call frame of
8328 scm_boot_guile was not completely protected from gc).
8330 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
8332 * ports.h (scm_port_table): put back file_name, it will be used to
8333 support debugging. Undo related changes in fports.c, ioext.c,
8336 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
8338 * ports.h (scm_port_table): remove file_name member for now, it seems
8340 * fports.c (scm_open_file): don't set file_name in PTAB.
8341 (prinfport): don't use file_name in PTAB.
8342 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
8343 * ports.c (scm_add_to_port_table): don't intialize file_name.
8344 (scm_port_file_name): remove for now.
8345 * gc.c (scm_gc_mark): don't mark PTAB file_name.
8347 * fports.h (scm_mkfile): prototype deleted.
8348 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
8350 * debug.c, unif.c: use scm_out_of_range instead of
8351 wta for range errors (ASSERT still needs work).
8353 * error.c, error.h (scm_out_of_range): new procedure.
8355 * error.c, error.h (scm_out_of_range_key): new key.
8357 * posix.c (scm_sync): #else was missing.
8359 * error.c, error.h: append _key to names scm_num_overflow and
8362 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
8363 of consing an empty list.
8364 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
8365 of macros, saves code and string space.
8366 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
8367 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
8368 lower case. Rename scm_syserror_m to scm_syserror_msg.
8369 error.h: prototypes for new procedures.
8371 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
8373 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
8375 * error.c, error.h: setup scm_num_overflow key.
8377 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
8378 Remove definition of SCM_OVSCM_FLOW.
8380 * fports.c (scm_open_file): use SCM_SYSERROR_M.
8382 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
8383 explicit message and args.
8385 * error.c, error.h, __scm.h: change system_error_sym to
8388 * error.c (system_error_sym): remove leading %% from the Scheme name
8391 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
8393 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8395 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
8396 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
8397 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
8398 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
8399 renamed. (These were introduced by unsupervised name
8402 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8404 * print.c: Added code for detection of circular references during
8405 printing. (init_ref_stack, grow_ref_stack): New functions. Added
8406 a hook for printing of closures (accessible via print options).
8407 This leads to a split of calls to scm_iprin1 into two classes:
8408 elementary print operations (e. g. the code which prints a smob)
8409 still use scm_iprin1 while top level calls (like scm_display) use
8410 scm_prin1. scm_prin1 begins by clearing the data structure used
8411 to record reference information.
8413 * print.h: Added declarations of scm_prin1 and scm_prlist.
8415 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
8417 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
8419 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
8421 * error.c (err_head): scm_iprin1 --> scm_prin1
8423 * debug.c: Adjusted header comment.
8427 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
8429 * strerror.c: Doc fix.
8431 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8433 * gdbint.c (gdb_read): Now possible to run during GC.
8434 (unmark_port, remark_port): New functions.
8436 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
8438 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
8439 of allocating a new string object. Also, increase size by
8440 the factor 2 instead of 1.5.
8442 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
8444 * __scm.h (SCM_P): Corrected to run under traditional C.
8446 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
8449 * async.c: Calls to scm_sysintern corrected.
8451 * async.h (scm_async_clock): Redundant declaration removed.
8453 * continuations.c (scm_dynthrow): Redundant declaration removed.
8455 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
8456 Definition typos corrected.
8458 * debug.h: Missing declarations of functions in debug.c added
8461 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
8462 Missing declarations to functions in eval.c added.
8464 * filesys.c: Possibly uninitialized variable rv.
8466 * gc.h (scm_object_addr, scm_unhash_name): Missing
8467 declarations of functions defined in gc.c added.
8469 * genio.c: Possible typos str_data -> wstr_data. ???
8471 * genio.c: Possibly unintended shadowing of local variable
8472 `int c' (gotos out of scope of inner `c'). ???
8474 * init.c: Uninitialized `SCM last' may be used.
8476 * ioext.h: (scm_sys_isatty_p): Typo.
8478 * list.h (scm_list_head): Missing prototype for function in
8481 * numbers.c (scm_two_doubles): Changed from extern to static
8482 (is used only within numbers.c).
8484 * numbers.h: Repeated declarations removed.
8486 * ports.h (scm_close_all_ports_except): Declaration for the
8487 function defined in ports.c added.
8489 * posix.h: Missing declarations added.
8491 * procs.h (scm_make_subr_opt): Missing declaration added.
8493 * socket.h (scm_sys_gethost): Missing declaration added.
8495 * socket.h: Redundant declarations removed (they are in fdsocket.h).
8497 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
8498 Missing declarations added.
8500 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
8502 * struct.c: Uninitialized variable `SCM answer' may be used.
8504 * unif.c (l2ra): Declaration prototype.
8506 * unif.c (scm_array_equal_p): Dummy definition removed (it is
8507 defined in ramap.c).
8509 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
8510 Redundant declarations removed (they are in ramap.h).
8512 * variable.h (scm_make_udvariable,
8513 scm_make_undefined_variable): Declaration corrected to
8514 correspond variable.c.
8516 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
8517 Missing declarations added.
8519 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
8521 * Makefile.in (distclean): Don't forget to delete fd.h.
8523 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
8525 * fd.h.in, tags.h: Trivial cleanups.
8527 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
8528 marksweep.h just declared functions from gc.c.
8529 * gc.h, libguile.h: Don't #include "marksweep.h".
8530 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
8531 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
8532 dependencies updated.
8534 * libguile.h: Don't #include "files.h"; it's been deleted.
8536 * files.c (scm_sys_delete_file): Moved to filesys.c.
8537 File is now empty; deleted.
8539 * filesys.c: scm_sys_delete_file is now here. Remove
8540 #if's; they seem to rely on remnants of an old portability
8541 regimen. If the problems come up again, solve them properly,
8542 using autoconf. Specifically: Don't test M_SYSV, and #define
8543 remove to be unlink if it's #defined; don't use remove just
8544 because HAVE_STDC_HEADERS is #defined.
8545 * filesys.h: Add declarations for scm_sys_delete_file.
8546 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
8547 files.o, files.h, files.c, and files.x.
8548 * init.c: Don't #include "files.h", and don't call scm_init_files.
8550 Use SCM_P instead of PROTO; the latter intrudes on the user's
8552 * params.h: Deleted; definition of SCM_P moved to...
8553 * __scm.h: ... here, where it replaces PROTO macro.
8554 * libguile.h, smob.h: Don't #include "params.h".
8555 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
8556 smob.h: Fix prototypes accordingly.
8557 * Makefile.in: Update dependencies.
8558 (inner_h_files): Remove params.h.
8560 * gc.c: #include "gc.h"; every module should include its header,
8561 to let the compiler cross-check the declarations against the
8564 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
8565 simpos.h: #include "libguile/__scm.h".
8567 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
8569 * init.c: Don't forget to #include smob.h and init.h.
8570 * Makefile.in: Dependencies updated.
8572 * smob.h: Use PROTO instead of #if __STDC__.
8574 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
8576 * __scm.h: Doc fixes.
8578 * __scm.h, libguile.h: Use "quotes" in the #includes, not
8579 <angles>; this allows `make depends' to work properly.
8581 * libguile.h: #include smob.h and pairs.h before the others; they
8582 define typedefs used by other headers.
8584 C files should #include only the header files they need, not
8585 libguile.h (which #includes all the header files); the pointless
8586 recompilation was wasting my time.
8587 * Makefile.in (all .o dependency lists): Regenerated.
8588 * libguile.h: Don't try to get a definition for size_t here...
8589 * __scm.h: Do it here.
8590 * _scm.h: Since this is the internal libguile header, put things
8591 here that all (or a majority) of the libguile files will want.
8592 Don't #include <libguile.h> here; that generates dependencies on
8593 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
8594 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
8595 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

8692 * weaks.c: Get "weaks.h".
8694 * stackchk.h: #include "libguile/debug.h",
8696 * print.h, read.h: #include "options.h", since everyone who uses
8697 either of these files will need that.
8699 * smob.h: #include "ports.h", "genio.h", and "print.h", since
8700 anyone who uses this file will need them to define the smob
8701 printing functions. Also, get markers.h, since people will need
8702 to #define the mark functions.
8704 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
8705 * ports.h: ... to here.
8707 * ports.h (scm_port_table_size): Explicitly give type as 'int';
8708 don't rely on archaic C default type rules.
8710 * fports.h: #include "libguile/ports.h", since you need that in
8711 order to parse this.
8713 * genio.h: #include "libguile/print.h", because you need that to
8714 parse this; don't bother #including "ports.h", since print.h gets
8717 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
8719 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
8720 this; it's now a reference to an element of *scm_root.
8722 * debug.h: Don't #include "options.h"; the compiler won't be able
8723 to find that once the headers are installed; instead, #include
8724 "libguile/options.h".
8725 * gc.h: Same, with marksweep.h.
8726 * mbstrings.h: Same, with symbols.h.
8727 * scmhob.h: Same, with _scm.h.
8728 * smob.h: Same, with params.h.
8730 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
8731 C files; there's no need for this, and it forces recompilations
8734 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
8736 * error.c (scm_error): declare scm_error_callback.
8738 * error.h: prototype for scm_error_callback.
8740 * __scm.h: define lgh_error.
8741 (SCM_SYSERROR): redefine using lgh_error.
8743 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
8745 * error.c (scm_error): new procedure.
8747 * error.h: prototype for scm_error.
8749 * Makefile.in (install): install scmconfig.h from the current
8750 directory, not $(srcdir).
8752 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8754 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8755 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8756 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

8762 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8763 vports.h, weaks.h: #include "libguile/__scm.h", not
8764 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
8765 dependencies are within libguile properly.
8767 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8769 * Makefile.in (.c.x): Simplify; there's no need to run this rule
8770 when scmconfig.h doesn't exist.
8772 * load.c (scm_sys_try_load): Correct spelling.
8774 * feature.c (scm_loc_features): Make this static.
8776 * Makefile.in (libpath.h): Omit trailing slash from path. We
8777 shouldn't require it of users, so why put it here?
8779 Move code to initialize and search %load-path from ice-9 to C
8780 code, so we can use the load-path to find the ice-9 boot code;
8781 this makes it easier to run Guile without installing it. See
8782 corresponding changes in guile/Makefile.in.
8783 * feature.c: Move stuff concerned with the load path to load.c.
8784 (scm_compiled_library_path): Deleted.
8785 Don't #include libpath.h here.
8786 * feature.h: Don't mention scm_compiled_library_path.
8787 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
8788 <sys/stat.h>, and <unistd.h> (if present).
8789 (R_OK): #define if the system hasn't deigned to.
8790 (scm_loc_load_path): New variable.
8791 (scm_init_load_path, scm_sys_search_load_path,
8792 scm_sys_try_load_path): New functions.
8793 (scm_init_load): Initialize scm_loc_load_path to point to the
8794 value cell of the Scheme %load-path variable.
8795 * load.h: Add declarations for scm_sys_search_load_path,
8796 scm_sys_try_load_path.
8797 * init.c: Call scm_init_load_path.
8798 * Makefile.in (feature.o, load.o): Dependencies updated.
8800 * load.c, load.h: Rewrite using PROTO macro.
8802 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8804 * gc.c (scm_cellp): New function: C predicate to determine if an
8805 SCM value can be regarded as a pointer to a cell on the heap.
8807 * gc.h: Added declaration of scm_cellp.
8809 * gdb_interface.h: New file: The GDB interface header from the GDB
8812 * gdbint.c: New file: GDB interface.
8814 * gdbint.h: New file: GDB interface.
8816 * libguile.h: Added #include <libguile/gdbint.h>.
8818 * init.c (scm_boot_guile): Added scm_init_gdbint.
8820 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
8821 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
8822 found if object files and source are kept separate).
8824 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
8826 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
8828 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
8830 * configure.in: Don't substitute the values of TCL_SRC_DIR and
8831 TK_SRC_DIR; they're not relevant any more.
8833 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
8834 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
8836 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
8838 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
8839 search path, so we can find the <libguile/MUMBLE.h> headers.
8841 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
8843 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
8844 implicit in the .c.o rule.
8845 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
8848 Put the library path in a header file, instead of passing it on
8849 the command line in every compilation.
8850 * Makefile.in (libpath.h): New target.
8851 (feature.o): Depend on libpath.h.
8852 (clean): Delete libpath.h.
8853 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
8854 * feature.c: ... #include "libpath.h" here.
8855 * .cvsignore: Ignore libpath.h.
8857 Don't install the unwashed masses of Guile header files in the
8858 main #include path; put most of them in a subdirectory called
8859 'libguile'. This avoids naming conflicts between Guile header
8860 files and system header files (of which there were a few).
8861 * Makefile.in (pkgincludedir): Deleted.
8862 (innerincludedir): New variable; this and $(includedir) are enough.
8863 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
8864 (installed_h_files): Divide this up. Now this variable lists
8865 those header files which should go into $(includedir) (i.e. appear
8866 directly in the #include path), and ...
8867 (inner_h_files): ... this new variable says which files appear in
8868 a subdirectory, and are referred to as <libguile/mumble.h>.
8869 (h_files): List them both.
8870 (install): Create innerincludedir, not pkgincludedir. Put
8871 the installed_h_files and inner_h_files in their proper places.
8872 (uninstall): Corresponding changes.
8873 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8874 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8875 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
8876 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
8877 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
8878 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8879 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8880 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8881 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8882 vports.h, weaks.h: Find __scm.h in its new location.
8883 * __scm.h: Find scmconfig.h and tags.h in their new locations
8884 (they're both "inner" files).
8886 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
8888 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
8890 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
8892 * posix.c: Doc fixes.
8894 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
8896 * socket.c: Don't include a prototype for inet_aton; just use a
8897 K&R style declaration, to avoid warnings but minimize the chance
8898 of conflicts with the system.
8900 On NextStep, <utime.h> doesn't define struct utime, unless we
8901 #define _POSIX_SOURCE before #including it.
8902 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
8903 * acconfig.h: New comment text for above CPP symbol.
8904 * configure.in: Call it.
8905 * posix.c: #define _POSIX_SOURCE if it seems necessary.
8907 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
8909 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
8910 testing for __EMX__.
8912 * posix.c: #include <libc.h>, if it exists.
8914 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
8915 don't even know if the latter exists.
8917 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
8918 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
8919 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
8921 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
8923 (scm_init_posix): Use them when initializing the Scheme constants
8926 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
8928 * Makefile.in (libdir, includedir, bindir): Use the
8929 autoconf-supplied values, instead of deriving them ourselves.
8930 (pkgincludedir, datadir, pkgdatadir): New variables.
8931 (install, uninstall): Put the header files in a special
8932 subdirectory, not in the main search path.
8934 * Makefile.in (ALL_CFLAGS): Provide the proper value for
8935 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
8937 * Makefile.in (IMPLPATH): Deleted; never used.
8939 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
8940 on the Tcl/Tk source any more.
8941 (INCLUDE_CFLAGS): Remove references to the above.
8943 * Makefile.in (version.o): Corrected dependencies.
8945 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8947 * libguile.h: #include "version.h"
8949 * init.c (scm_boot_guile): Call scm_init_version.
8950 * gscm.c (gscm_run_scm): Call scm_init_version.
8952 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8953 GUILE_VERSION): AC_DEFINE these.
8954 (acconfig.h): #undef the above symbols.
8956 * Makefile.in (libobjs): Add version.o.
8957 (installed_h_files): Add version.h.
8958 (c_files): Add version.c.
8959 (gen_c_files): Add version.x.
8960 (version.o): New rule.
8961 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
8962 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
8963 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
8964 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
8965 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
8966 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
8967 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
8968 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
8969 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
8970 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
8971 weaks.o): Add version.h to dependency lists.
8972 (markers.o): Remove duplicate rule.
8974 * version.h: New file.
8976 * version.c: New file.
8978 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8980 * symbols.c (scm_strhash): scm_downcase is now a function, not an
8981 array; use it appropriately. Since GCC is quite happy to
8982 subscript functions, it never warned us about this; we should use
8983 -Wpointer-arith in the future. I guess we never tested
8986 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
8988 * socket.c: Doc and copyright fixes.
8990 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8992 * debug.c: Fixed and improved gdb support.
8994 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8996 * socket.c: Added declaration of inet_aton to avoid compiler
8997 warning. (Hope this solution is correct.)
8999 * stime.c: Added declaration of ftime. (This is missing in
9002 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
9004 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
9006 * Makefile.in (c_files): add strerror.c.
9008 * strerror.c: new file from Emacs' sysdep.c.
9009 maybe configure should also check for sys_errlist.
9011 * configure.in (AC_REPLACE_FUNCS): add strerror.
9013 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
9015 * debug.c (scm_init_debug): Added initialization for
9016 scm_evaluator_traps.
9018 * debug.h, debug.c: Various name changes.
9019 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
9020 "debug-options-interface". See commentary in options.c.
9022 * options.h, options.c: Options now have documentation strings.
9023 Also added a long explanatory commentary.
9025 * eval.c, print.h, print.c, read.h, read.c: Modifications to
9028 * gscm.c, init.c, root.c, throw.c: Bug fixes:
9029 last_debug_info_frame is now updated in all cases.
9031 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
9034 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
9036 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
9037 Added option STACK_CHECKING.
9039 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
9041 * Makefile.in: Added {debug,options,srcprop}.{h,c}
9043 * __scm.h: Removed symbols for debugging support.
9045 * acconfig.h: Added symbols for debugging support.
9047 * configure.in: Added user option for debugging support.
9048 --enable-debug will include the debugging code into libguile.a.
9050 * continuations.c (scm_make_cont): Enlarged the #if 0 around
9051 scm_relocate_chunk_to_heap.
9053 * debug.c: New file: low-level debugging support. It also
9054 includes support for debugging with gdb. (The extensions to gdb
9055 are written by Per Bothner at Cygnus.)
9057 * debug.h: New file: low-level debugging support.
9059 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
9060 argument pairs. Extensive modifications to the debugging
9061 evaluator. Added "SECTION:" commentaries to clarify what happens
9062 when, during double compilation. Renamed EVALIMP --> EVALIM.
9063 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
9064 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
9065 the beginning of the file. New procedure: scm_unmemocopy.
9066 Added some global state variables needed by the debugging
9067 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
9068 check_entry, check_apply, check_exit, debug_options and
9069 evaluator_traps. New acro: undefine.
9071 * eval.h: Renamed EVAL --> XEVAL.
9073 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
9074 --> scm_make_weak_key_hash_table.
9076 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
9077 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
9079 * libguile.h: Conditionally include debug.h
9081 * objprop.c (scm_object_properties, scm_set_object_properties_x):
9082 scm_object_properties shouldn't return handle. `handle' now gets
9083 initialized in scm_set_object_properties_x. scm_object_properties
9084 doesn't any longer create an entry in scm_object_whash.
9086 * options.c: New file: handling of run time options.
9088 * options.h: New file: handling of run time options.
9090 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
9092 * print.c: New procedure: scm_print_options
9094 * print.h: Defines for print options.
9096 * read.c: New procedure: scm_read_options
9098 * read.h: Defines for reader options.
9100 * root.h: Added scm_source_whash among scm_sys_protects.
9102 * srcprop.c: New file: source properties.
9104 * srcprop.h: New file: source properties.
9106 * throw.c (jbsmob): Jump buffers are now correctly allocated.
9107 (Bug found by A. Green.)
9109 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
9111 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
9113 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
9115 * libguile.h: #include "objprop.h"; I guess this was forgotten.
9117 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
9118 and should be called by the final client.
9120 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
9122 * gc.h: Use the PROTO macro when declaring functions.
9123 * gc.c: Use the PROTO macro when declaring static functions.
9124 Remove the CPP hair around function definitions.
9126 * gc.c (scm_init_storage): Initialize scm_asyncs.
9128 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
9129 preprocessor symbol; "__scm.h" is where it might get #defined.
9130 * __scm.h: Similar: #include <scmconfig.h> before testing
9133 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
9135 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
9137 * init.c (scm_boot_guile): Add init_func argument; call
9138 (*init_func) instead of calling scm_appinit; it's ucky to
9139 hard-code names for the user's procedures.
9140 * init.h (scm_boot_guile): Adjust declaration.
9142 * __scm.h (PROTO): New macro, for declaring functions with
9145 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
9146 eliminate all the __STDC__ conditionals.
9147 (scm_boot_guile): Add declaration.
9148 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
9149 Remove __STDC__ conditionals around function definitions; the
9150 declarations in init.h will provide the same information, more
9153 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
9154 complain about it in the error message; the error message is
9155 adequate without that note, and there's nothing the user can do
9158 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
9160 * Makefile.in (ancillary): Drop def.sed.
9162 * posix.c (scm_init_posix): Use numeric values, rather than
9163 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
9164 F_OK. The symbols aren't available on some systems, and I'm
9165 pretty sure their values are fixed by common widespread practice.
9166 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
9168 More functions unavailable on some systems.
9169 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
9170 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
9172 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
9173 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
9174 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
9175 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
9176 stub that signals an error as the #else.
9178 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
9180 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
9182 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
9184 * unif.c: include ramap.h.
9186 * read.c (endif): case_insensative_p renamed case_insensitive_p.
9188 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
9190 * ports.c: include sys/ioctl.h.
9192 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
9194 * configure.in: check for sys/ioctl.h.
9196 * ports.c: include <malloc.h> not "malloc.h".
9198 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
9200 * fports.c: remove ttyname and tmpnam declarations.
9202 * posix.c: fewer ttyname declarations.
9204 * fports.c: include <string.h> not "string.h".
9206 * init.c, ioext.c: include string.h and unistd.h.
9208 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
9210 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
9211 genio.c, simpos.c, vports.c: include string.h.
9213 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
9215 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
9217 (scm_addr_buffer_size): change type from scm_sizet to int.
9218 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
9219 from scm_sizet to int.
9221 * error.c: include unistd.h.
9223 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
9226 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
9228 * __scm.hd, def.sed: deleted.
9230 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
9232 Changes for NeXT, suggested by Robert Brown.
9233 * configure.in: Call AC_TYPE_MODE_T.
9234 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
9235 NeXT. Put header file list in alphabetical order.
9236 * configure, scmconfig.h.in: Regenerated.
9237 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
9239 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
9242 * acconfig.h: New file, providing documentation for the CPP
9243 symbols defined in configure.in
9244 * acconfig-1.5.h: Removed; superceded by the above.
9246 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
9248 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
9250 * fports.c (scm_open_file): don't return #f, throw error.
9252 * ioext.c (fileno): renamed from %fileno.
9253 (soft-fileno): deleted.
9255 * ports.c (scm_port_revealed): don't need to check for -1 from
9257 (scm_set_port_revealed_x): return unspecified, not #f.
9259 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
9261 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
9263 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
9265 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
9267 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
9269 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
9270 This is necessary on Ultrix, and doesn't hurt portability.
9272 * Makefile.in (dist-dir): New target, implementing a new dist system.
9273 (installed_h_files): Put in alphabetical order.
9274 Remove duplicate entries for markers.h and unif.h.
9275 (c_files): Remove duplicate entries for markers.c.
9276 (ancillary): Renamed from anillery; all uses changed. Remove
9277 PLUGIN; it's a directory, and needs special treatment in dist-dir.
9278 Remove all the ../doc/* files; doc/Makefile.in handles that.
9280 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
9282 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
9283 every if must have an else, or else the whole command has a

9543 initialization to fix a race condition.
9545 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
