1 2000-01-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3 * eval.c (SCM_CEVAL): Optimization: Reverse order of
4 scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P => speed
5 gain 4-6% for eval1 benchmark on one machine. (Thanks to Brad
8 Mon Jan 3 08:30:02 2000 Greg Harvey <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
10 * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
13 * pairs.h: Added a comment about the need for the SCM_SETCAR in
16 Mon Jan 3 08:25:19 2000 Greg J. Badros <gjb@cs.washington.edu>
18 * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
19 SCM_NIMP tests that were redundant are now eliminated. Patches
20 from Dirk Hermann applied by hand.
22 1999-12-28 Gary Houston <ghouston@arglist.com>
24 * posix.c (scm_waitpid): move the HAVE_WAITPID test out of the
25 procedure body, so that the procedure is left undefined if waitpid
26 is not available. previously in this case the procedure was
27 defined but would raise a system-error when called, which is
28 pointless. I intend to make the same change for other procedures
29 and deprecate SCM_SYSMISSING and scm_sysmissing.
31 1999-12-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
33 * feature.c (s_scm_add_hook_x): Call scm_wrong_type_arg instead of
34 scm_misc_error when add-hook! is passed a procedure of wring
35 arity. (Thanks to Greg Harvey.)
37 1999-12-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
39 * macros.c (scm_make_synt): Use scm_make_subr_opt to make the
40 transformer subr. (Thanks to Bill Schottstaedt.)
42 1999-12-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
44 * objects.c (scm_class_of): Bugfix: Inserted missing SCM_CDR
45 setting struct table class.
47 Sun Dec 19 10:22:34 1999 Greg J. Badros <gjb@cs.washington.edu>
49 * threads.c, mit-pthreads.c, list.c, coop.c: Remove K&R
50 prototypes; just use ANSI C prototypes. I'm not sure how
51 mit-pthreads.c ever compiled -- it still doesn't for me, but the
52 normal make procedure does not try to build it anyway (even
53 --with-threads I get the other threads code building) so I'm not
56 Sat Dec 18 16:58:34 1999 Greg J. Badros <gjb@cs.washington.edu>
58 * tags.h (SCM_CONSP, SCM_NCONSP): Define these in terms of
59 SCM_SLOPPY_CONSP and SCM_SLOPPY_NCONSP. (SCM_CONSP) Define this
60 in terms of SCM_SLOPPY_NCONSP instead of repeating the
63 * symbols.h (SCM_SLOPPY_SUBSTRP, SCM_SUBSTRP): Added former, and
64 define latter in terms of sloppy variant.
66 * strings.h (SCM_SLOPPY_STRINGP, SCM_STRINGP): Added former, and
67 define latter in terms of sloppy variant.
69 * scm_validate.h (SCM_MAKE_VALIDATE): Added this macro to factor
70 out the commonality of the various basic SCM_VALIDATE_foop
71 macros. Use SCM_MAKE_VALIDATE macro where possible. Fix
72 SCM_VALIDATE_INT_COPY to not use scm_num2ulong -- that does
73 coercion to an integer which is more advanced than desired and
74 SCM_NUM2ULONG provides that functionality. Use SCM_ASSERT_RANGE
75 appropriately for the various _MIN, _MAX, _RANGE macros. Drop
76 some superfluous "SCM_NIMP &&" where possible. Eliminate obsoleted
77 SCM_VALIDATE_NIMCONS (SCM_VALIDATE_CONS now does the NIMP test as
78 part of its SCM_CONSP test).
80 * socket.c, ports.c, pairs.c, list.c, lang.c, async.c: Use
81 SCM_VALIDATE_CONS, not obsoleted SCM_VALIDATE_NIMCONS.
83 Sat Dec 18 15:33:05 1999 Greg J. Badros <gjb@cs.washington.edu>
85 * dynl.c: Added #include "scm_validate.h"
87 Sat Dec 18 15:22:10 1999 Greg J. Badros <gjb@cs.washington.edu>
89 * alist.c, chars.c, dynl.c, net_db.c, numbers.c, unif.c: Use
90 SCM_NUM2ULONG instead of scm_num2ulong; SCM_NUM2LONG instead of
91 scm_num2long; SCM_WTA instead of scm_wta. Only done for when
92 FUNC_NAME was used as an argument of the macro and the formal
93 argument name was the explicit argument in the old function call.
94 These were just missed in my first pass of changes.
96 1999-12-18 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
98 * guile-doc-snarf.in (filename): Strip path to source dir before
99 touching the .x-files.
101 1999-12-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
103 * debug.c (scm_reverse_lookup): Bugfix: Reinserted SCM_NIMP.
105 * eval.c (SCM_CEVAL): Removed check for unbound slot in
106 SCM_IM_SLOT_REF. (This is now handled in a smarter way in GOOPS.)
108 1999-12-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
110 * tags.h (SCM_SLOPPY_NCONSP, SCM_SLOPPY_CONSP): New macros.
111 (SCM_ECONSP): Version which doesn't mix && and || without
113 (SCM_NECONSP): Bugfree version.
115 Fri Dec 17 12:09:11 1999 Greg J. Badros <gjb@cs.washington.edu>
117 * tags.h (SCM_ECONSP, SCM_NECONSP): Fix these macros to have the
118 SCM_NIMP test integrated into an || clause that I'd missed before
119 and was causing a segfault in the regression tests.
121 * symbols.h (SCM_ROUCHARS): Make cast be to (unsigned char *), not
122 (char *); fixes a problem reported by the regression test
125 * ports.c: Fixed a couple of arg/number mismatches in
126 SCM_VALIDATE_ macros.
128 Now passes the (not-comprehensive) guile-modules test-suite again!
130 Thu Dec 16 12:41:22 1999 Greg J. Badros <gjb@cs.washington.edu>
132 * coop-threads.c: Remove K&R function headers.
134 * scm_validate.h: Added SCM_VALIDATE_THREAD.
136 * *.c: Remove SCM_NIMP(X) when it is an extraneous pre-test given
137 that SCM_FOOP macros all now include SCM_NIMP in their expansion.
138 This simplifies lots of code, making it far more readable.
140 Wed Dec 15 19:45:14 1999 Greg J. Badros <gjb@cs.washington.edu>
142 * *.h: Use SCM_NIMP(X) && in all the FOOP macros.
144 * *.[ch]: Use do { ... } while (0) idiom in macros that expanded
147 Tue Dec 14 10:53:14 1999 Greg J. Badros <gjb@cs.washington.edu>
149 * snarf.h: Put SCM_PROC and SCM_PROC1 back in for
150 backward-compatibility of packages that use Guile. Internally
151 Guile should not use them, though. (Maybe enforce this with a new
152 -DBUILDING_GUILE compile-time flag?).
154 Tue Dec 14 09:41:01 1999 Greg J. Badros <gjb@cs.washington.edu>
156 * backtrace.c (scm_set_print_params_x): Renamed from
159 * guile-doc-snarf.in: Use guile-snarf.awk, not
160 guile-doc-snarf.awk. Pass the basename of $filename
162 * load.h: Added prototypes for scm_sys_library_dir,
165 * load.c (scm_sys_library_dir, scm_sys_site_dir): Added these
166 functions, and took out the old scm_library_dir, scm_site_dir,
167 scm_pkgdata_dir. Now the primitives are %package-data-dir
168 (already existed), %library-dir, and %site-dir.
170 * debug.c: Use SCM_MISC_ERROR when possible instead of using
171 s_scm_* in a scm_misc_error() call.
173 * Makefile.am: Use guile-snarf.awk, not guile-doc-snarf.awk. Make
174 using guile-doc-snarf send stdout to $@ to create the .x file like
177 * guile-snarf.awk.in: Added.
179 * guile-doc-snarf.awk.in: Removed (sorry to back out a recent
180 commit; if we're going to switch to guile-snarf I figure it makes
181 sense to get this right now-- I'd already had the change in my
182 working copy when the below commit happened).
184 1999-12-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
186 * guile-doc-snarf.awk: Removed.
188 * guile-doc-snarf.awk.in: Added.
190 * ports.c (s_scm_pt_member): Fixed validation.
192 * guile-doc-snarf.in (filename): Use basename in order to strip
195 * debug.c (scm_make_iloc, s_scm_proc_to_mem): Added missing
197 (scm_memcons, scm_memcons, mem_to_proc): Renamed function name
200 * backtrace.c (set_print_params_x): Fixed GUILE_PROC macro.
202 * tags.h (SCM_UNBOUND): New iflag which is needed for some time to
203 mark the unboundness of a GOOPS slot. (Added now in order to
204 correct a oversight. Should probably be removed again and
205 replaced with SCM_UNDEFINED when the corresponding code in GOOPS
208 * print.c (scm_isymnames): Added printed representation for
211 * eval.c (SCM_CEVAL): Bugfix: Added check for unbound slot in
214 Mon Dec 13 17:23:22 1999 Greg J. Badros <gjb@cs.washington.edu>
216 * strings.c: Fixed mistaken default value in
217 scm_make_shared_substring; thanks Eric Moore!
219 Mon Dec 13 16:29:13 1999 Greg J. Badros <gjb@cs.washington.edu>
221 * guile-doc-snarf.awk: Use sub instead of gsub in ^ anchored
222 replacement for docstrings. Fixes problem Ryan Yeske observed
223 with using mawk on his system. Thanks Ryan!
225 Mon Dec 13 13:30:06 1999 Greg J. Badros <gjb@cs.washington.edu>
227 * guile-doc-snarf.in: Do not echo to stdout since the output now
228 gets stuck directly in the files instead of redirected from
231 * guile-doc-snarf.awk: Escape a literal ) -- thanks Ryan
232 Yeske. Use print instead of printf to prime the .x file since
233 AIX's cpp has problems with #include-ing empty files (according to
234 the old guile-snarf.in file).
236 Sun Dec 12 19:39:00 1999 Greg J. Badros <gjb@cs.washington.edu>
238 * Makefile.am: Fix ETAGS_ARGS to recognize GUILE_PROC,
239 GUILE_PROC1. Build guile-procedures.txt, and add that file to
242 * load.c: Added `pkgdata-dir', `site-dir', `library-dir'
245 * guile-doc-snarf.awk: Drop trailing space when no arguments:
246 e.g., "(foo )" is now "(foo)".
248 * *.c, alist.c: moved all the documentation for primitives from
249 guile-doc/ref/{appendices,posix,scheme}.texi into the source code.
250 This leaves about half of the primitives undocumented. Also, all
251 the markup is currently still texinfo. I don't have a problem
252 with texinfo per se, but the markup is not very descriptive or
255 Sun Dec 12 16:50:26 1999 Greg J. Badros <gjb@cs.washington.edu>
257 * scm_validate.h: Drop the SCM_DOCSTRING_SNARF for turning off
258 SCM_VALIDATE macros; the SCM_VALIDATE macros should be checked for
259 argument mismatches (along with the FUNC_NAME macro checking) by a
260 static tool that runs directly over the .c files.
262 * snarf.h: Handle SCM_REGISTER_PROC better when snarfing. The
263 docstring is still missing from the .doc file; it just gives the
264 name of the C function that gets called instead.
266 * guile-doc-snarf.awk: Be sure to touch the output files to help
267 make out. Also handle SCM_REGISTER_PROC better, and change the
268 output format slightly.
270 Sun Dec 12 15:33:40 1999 Greg J. Badros <gjb@cs.washington.edu>
272 * snarf.h: Drop SCM_PROC, SCM_PROC1. Added extra output for
273 guile-doc-snarf script.
275 * guile-doc-snarf.in, guile-doc-snarf.awk: New, simple doc
276 extraction system. Builds foo.x, foo.doc from foo.{c,cc}.
277 There are dependencies between these files and snarf.h. This
278 replaces guile-snarf.
280 * guile-snarf.in: Drop everything after $$$ for the new snarf.h
281 macros. This is obsoleted by guile-doc-snarf, but kept here for
282 now for good measure.
284 * Makefile.am: Added guile-doc-snarf, guile-doc-snarf.awk to
285 bin_SCRIPTS. Added .doc to SUFFIXES, and give rule for creating
286 .doc files to use guile-doc-snarf. Update the rule for creating
287 .x files to use guile-doc-snarf.
289 Sun Dec 12 12:31:38 1999 Greg J. Badros <gjb@cs.washington.edu>
291 * *.c: Finish replacing K&R style prototypes with ANSI C
294 * eval.c: Make scm_m_mody's 3rd argument be a const char *, not a
295 char *. ANSI prototypes caught this.
297 * strorder.c: Use GUILE_PROC1 for the couple SCM_PROC1 expansions
300 * scm_validate.h: Use SCM_BOOLP for validating bools. Do not
301 expand macros if SCM_DOCSTRING_SNARF.
303 Sun Dec 12 11:23:22 1999 Greg J. Badros <gjb@cs.washington.edu>
305 * *.c, srcprop.h: Use SCM_BOOL(f) instead of (f? SCM_BOOL_T:
306 SCM_BOOL_F) and use SCM_NEGATE_BOOL(f) instead of (f? SCM_BOOL_F:
309 Sun Dec 12 11:08:51 1999 Greg J. Badros <gjb@cs.washington.edu>
311 * boolean.h: Added SCM_BOOL, SCM_NEGATE_BOOL, SCM_BOOLP to here,
314 * scm_validate.h: Moved above out into boolean.h, fix typo in
315 SCM_VALIDATE_NIM macro.
317 Sun Dec 12 10:29:12 1999 Greg J. Badros <gjb@cs.washington.edu>
319 * *.c, scm_validate.h: Use SCM_VALIDATE_NIM, not SCM_VALIDATE_NIMP
320 (none of the other validate macros have the trailing P).
322 Sun Dec 12 10:07:29 1999 Greg J. Badros <gjb@cs.washington.edu>
324 * scm_validate.h: Added the FSF copyright to the top.
326 * strings.c: Use SCM_ASSERT_RANGE in a couple of places instead of
327 SCM_ASSERT w/ SCM_OUT_OF_RANGE.
329 Sat Dec 11 18:34:12 1999 Greg J. Badros <gjb@cs.washington.edu>
331 * Makefile.am: Added scm_validate.h to modinclude_HEADERS.
333 * *.c: Pervasive software-engineering-motivated rewrite of
334 function headers and argument checking. Switched SCM_PROC,
335 SCM_PROC1 macros to be GUILE_PROC, GUILE_PROC1 (may change names
336 later, but was useful to keep old versions around while migrate)
337 that has docstrings and argument lists embedded in the GUILE_PROC
338 macro invocations that expand into a function header. Use lots of
339 new SCM_VALIDATE_* macros to simplify error checking and reduce
340 tons of redundancy. This is very similar to what I did for Scwm.
342 Note that none of the extraction of the docstrings, nor software
343 engineering checks of Scwm is yet added to Guile. I'll work on
344 that tomorrow, I expect.
346 * chars.c: Added docstrings for the primitives defined in here.
348 * snarf.h: Added GUILE_PROC, GUILE_PROC1. Added
349 SCM_REGISTER_PROC to be like old SCM_PROC, though old SCM_PROC
350 still remains for now. Changed naming convention for the s_foo
351 string name of the primitive to be s_scm_foo for ease of use with
354 * scm_validate.h: Lots of new SCM_VALIDATE macros to simplify
355 argument checking through guile. Maybe some of these should be
356 folded into the header file for the types they check, but for now
357 it was easiest to just stick them all in one place.
359 1999-12-10 Greg Harvey <Greg.Harvey@thezone.net> (applied --12/10/99 gjb)
361 * smob.c (scm_smob_prehistory): initialize allocated smob
363 * tags.h: new tag: scm_tc16_allocated
365 * gc.c (scm_gc_for_newcell): set the car of the new cell
366 to scm_tc16_allocated
367 * pairs.h (SCM_NEWCELL): set the car to scm_tc16_allocated
368 (scm_gc_mark): mark allocated cells.
370 1999-12-09 Greg J. Badros <gjb@cs.washington.edu>
372 * strports.h, strports.c (scm_eval_0str): Fix constness. Some
373 thanks to Dirk Hermann.
375 * gh_eval.c (gh_eval_str, gh_eval_file, gh_eval_str_with_catch,
376 gh_eval_str_with_standard_handler,
377 gh_eval_str_with_stack_saving_handler): Fix constness. Some
378 thanks to Dirk Hermann.
380 * gh_data.c (gh_str02scm): Fix constness.
382 * gh.h: Fix constness of prototypes for the above.
384 * vectors.c: Include "unif.h" to avoid a warning about missing
385 prototype for scm_uniform_element_size().
387 1999-12-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
389 * vectors.c (scm_vector_length, scm_vector_ref, scm_vector_set_x):
390 Turned into primitive generics.
392 1999-12-04 Gary Houston <ghouston@freewire.co.uk>
394 * ports.c (scm_port_closed_p): new procedure, implements
395 "port-closed?" suggested by Bernard Urban.
396 ports.h: added prototype, removed the SCM_P macros.
398 1999-11-30 Gary Houston <ghouston@freewire.co.uk>
400 * unif.h: added some comments, removed the SCM_P macros.
402 1999-11-29 Gary Houston <ghouston@freewire.co.uk>
404 * vports.c (sf_write): use scm_makfromstr, not scm_makfrom0str
405 (thanks to Daniel Skarda).
407 1999-11-22 Jim Blandy <jimb@savonarola.red-bean.com>
409 * gscm.c, gscm.h: Deleted. They were unused.
411 1999-11-20 Gary Houston <ghouston@freewire.co.uk>
413 * unif.c (scm_list_to_uniform_array): call
414 scm_dimensions_to_uniform_array with a third argument of
415 SCM_UNDEFINED instead of SCM_EOL.
417 1999-11-19 Gary Houston <ghouston@freewire.co.uk>
419 * the following changes allow guile to be built with the array
420 "module" omitted. some of this stuff is just tc7 type support,
421 which wouldn't be needed if uniform array types were converted
424 * tag.c (scm_utag_bvect ... scm_utag_cvect): don't define unless
426 (scm_tag): don't check array types unless HAVE_ARRAYS.
428 * sort.c (scm_restricted_vector_sort_x, scm_sorted_p):
429 remove the unused array types.
430 * (scm_stable_sort, scm_sort): don't support vectors if not
431 HAVE_ARRAYS. a bit excessive.
433 * random.c (vector_scale, vector_sum_squares,
434 scm_random_solid_sphere_x, scm_random_hollow_sphere_x,
435 scm_random_normal_vector_x): don't define unless HAVE_ARRAYS.
437 * gh_data.c (makvect, gh_chars2byvect, gh_shorts2svect,
438 gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect, gh_doubles2dvect,
439 gh_uniform_vector_length, gh_uniform_vector_ref):
440 don't define unless HAVE_ARRAYS.
441 (gh_scm2chars, gh_scm2shorts, gh_scm2longs, gh_scm2floats,
443 don't check vector types if not HAVE_ARRAYS.
445 * eq.c (scm_equal_p), eval.c (SCM_CEVAL), print.c (scm_iprin1),
446 gc.c (scm_gc_mark, scm_gc_sweep), objects.c (scm_class_of):
447 don't support the array types unless HAVE_ARRAYS is defined.
449 * tags.h: make nine tc7 types conditional on HAVE_ARRAYS.
451 * read.c (scm_lreadr): don't check for #* unless HAVE_ARRAYS is
452 defined (this should use read-hash-extend).
454 * ramap.c, unif.c: don't check whether ARRAYS is defined.
456 * vectors.c (scm_vector_set_length_x): moved here from unif.c. call
457 scm_uniform_element_size if HAVE_ARRAYS.
458 vectors.h: prototype too.
460 * unif.c (scm_uniform_element_size): new procedure.
462 * init.c (scm_boot_guile_1): don't call scm_init_ramap or
463 scm_init_unif unless HAVE_ARRAYS is defined.
465 * __scm.h: don't define ARRAYS.
467 * Makefile.am (EXTRA_libguile_la_SOURCES): unif.c and ramap.c
468 moved here from libguile_la_SOURCES.
470 1999-11-18 Gary Houston <ghouston@freewire.co.uk>
472 * socket.c (scm_htons, scm_ntohs, scm_htonl, scm_ntohl): new
473 functions for network data conversion.
475 * numbers.c (scm_num2long, scm_num2longlong):
476 throw out-of-range instead of wrong-type-arg if appropriate.
477 (scm_iint2str): handle -2^31 correctly.
478 (scm_num2long): handle -2^31 bignum correctly.
479 (scm_num2long_long): rewrite the bigdig case: basically copied
481 numbers.h: (SCM_BITSPERLONGLONG): deleted.
483 * unif.c (rapr1): use sprintf instead of intprint for unsigned
484 longs: intprint can't cope with large values.
486 * numbers.c (scm_num2ulong): check more consistently that the
487 input is not negative. if it is, throw out-of-range instead of
490 * ramap.c (scm_array_fill_int): don't limit fill to INUM for
491 uvect, ivect or llvect.
492 Check that fill doesn't overflow short uniform array.
494 * __scm.h: add another long to the definition of long_long and
497 * unif.c (scm_raprin1): use 'l' instead of "long_long" in the
498 print representation of llvect. read can't handle more than
500 (scm_dimensions_to_uniform_array): make "fill" an optional argument
501 instead of a rest argument.
503 * tags.h (scm_tc7_llvect): wasn't defined anywhere, so use the free
506 * __scm.h: don't mention LONGLONGS.
508 * unif.c, numbers.c, eq.c, gc.c, print.c, eval.c, ramap.c:
509 replace LONGLONGS with HAVE_LONG_LONGS as set by configure.
511 1999-11-17 Gary Houston <ghouston@freewire.co.uk>
513 * net_db.c (scm_inet_aton): throw errors using the misc-error key
514 instead of system-error. inet_aton doesn't set errno.
515 system-error isn't right in gethost either, since it's throwing
516 the value of h_errno instead of errno. so:
517 (scm_host_not_found_key, scm_try_again_key,
518 scm_no_recovery_key, scm_no_data_key): new error keys.
519 (scm_resolv_error): new procedure, use the new keys.
520 (scm_gethost): call scm_resolv_error not scm_syserror_msg.
522 1999-11-16 Gary Houston <ghouston@freewire.co.uk>
524 * error.c: (various): use scm_cons instead of scm_listify
525 to build short lists.
527 1999-11-03 Gary Houston <ghouston@freewire.co.uk>
529 * socket.c (scm_fill_sockaddr): zero the address structure before
530 use, in case it has a sin_len field and the OS doesn't like random
531 values (thanks to Bertrand Petit).
533 1999-10-26 Mark Galassi <rosalia@lanl.gov>
535 * gh.h, gh_data.c (gh_symbol2scm): changed gh_symbol2scm() to take
536 a const char * argument, upon suggestion from Lynn Winebarger.
538 1999-10-26 Gary Houston <ghouston@freewire.co.uk>
540 * strports.c (st_end_input): avoid dubious pointer arithmetic.
542 1999-10-24 Gary Houston <ghouston@freewire.co.uk>
544 * Move the responsibility for resetting port buffers from the
545 caller of the ptob seek procedure to the implementation. This
546 gives more control in general to the ptob seek: in particular the
547 change of 1999-10-20 can be made to work without breaking seek on
548 string ports. There's a comment in NEWS about upgrading port
551 * ports.c (scm_seek): don't reset the port buffers here.
553 * fports.c (fport_seek): reset the buffers, except for the
556 * strports.c (st_end_input): (bug fix): decrement pt->read_pos by
557 offset. check that it's not less than read_buf.
558 (st_seek): reset the buffers first, unless it's the 0 SEEK_CUR
559 case and currently reading.
561 1999-10-20 Gary Houston <ghouston@freewire.co.uk>
563 * ports.c (scm_seek): Add a special case for SEEK_CUR, offset 0,
564 so that unread chars are not needlessly discarded. (thanks to
567 1999-10-18 Gary Houston <ghouston@freewire.co.uk>
569 * fports.c (scm_fdes_to_port): always set rw_random if the fdes is
570 random access. rw_active needs to be maintained even for single
571 directional ports, otherwise scm_seek and probably other things are
572 broken. (thanks to Roland Orre).
574 * strports.c (scm_mkstrport): set rw_random to 1 unconditionally.
576 * ports.c (scm_add_to_port_table): initialise rw_random to 0.
578 * ports.h (scm_port): change the comments on rw_random and rw_active.
580 1999-10-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
582 * ioext.c: Added #include "feature.h".
584 These changes turns `delay' into a memoizing macro. This is
585 because it may be expanded before evaluation if it occurs at the
586 beginning of a body. (Thanks to Lauri Alanko.)
588 * eval.c, eval.h (scm_sym_delay): New global symbol.
590 * tags.h (SCM_IM_DELAY): New immediate symbol.
592 * print.c (scm_isymnames): Printed representation.
594 * eval.c (unmemocopy, SCM_CEVAL): Handle SCM_IM_DELAY.
595 (scm_m_delay): Turned into a memoizing macro.
597 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version.
599 1999-10-11 Jim Blandy <jimb@savonarola.red-bean.com>
601 * gh_data.c (gh_ints2scm, gh_doubles2scm): Make sure elements are
602 protected from GC while building the vector. (Thanks to Bernard
603 Urban and Greg Harvey.)
605 1999-10-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
607 * throw.c (handler_message): Display backtrace if backtraces
610 1999-10-05 Jim Blandy <jimb@savonarola.red-bean.com>
612 * Makefile.in, scmconfig.h.in: Deleted from CVS repository. Run
613 the autogen.sh script to create generated files like these.
615 * numbers.c (scm_string_to_number): Signal an error if radix is
616 less than two. (Thanks to Jorgen Schaefer.)
618 * print.c (scm_write, scm_display, scm_newline, scm_write_char):
619 Don't assume that the current output port is valid. Somebody
620 might close it. (Thanks to Bernard Urban.)
622 1999-10-02 Jim Blandy <jimb@zwingli.cygnus.com>
624 * scmconfig.h.in: Regenerated.
626 * Makefile.am (EXTRA_libguile_la_SOURCES): fix typo.
628 Mon Sep 27 17:15:14 1999 Greg J. Badros <gjb@cs.washington.edu>
630 * __scm.h: Fix a bunch of macros that were missing do-while(0)
633 * debug.c, eval.c: Fix buggy uses of SCM_ALLOW_INTS (missing
634 semicolon) exposed by the above change.
636 1999-09-27 Greg J. Badros <gjb@cs.washington.edu>
638 * stacks.c: Avoid compiler warning re: unitialized var.
640 * scmconfig.h.in: Added DEBUG_FREELIST
642 * pairs.h: Fix macro that was not do-while(0) sandwiched.
644 * gc.h, gc.c: Added scm_gc_set_debug_check_freelist_x,
647 1999-09-23 Gary Houston <ghouston@freewire.co.uk>
649 * ioext.c (scm_init_ioext): enable "i/o-extensions" feature here
650 instead of in scm_init_filesys.
652 * init.c (scm_boot_guile_1): don't call scm_init_posix or
653 scm_init_filesys unless HAVE_POSIX is defined.
654 don't call scm_init_netdb or scm_init_socket unless
655 HAVE_NETWORKING is defined.
657 * Makefile.am (EXTRA_libguile_la_SOURCES): filesys.c, posix.c,
658 net_db.c, socket.c: moved here from libguile_la_SOURCES.
660 1999-09-25 Jim Blandy <jimb@savonarola.red-bean.com>
662 * root.c (scm_make_root): Initialize all the fields of the new
663 root. GC could happen any time, you know. (Thanks to Greg
666 * numbers.c (scm_number_to_string): Signal an error if radix is
667 less than two. (Thanks to Jorgen Schaefer.)
669 * Makefile.am (EXTRA_libguile_la_SOURCES): Add memmove.c here,
670 so automake will actually generate rules for it.
671 * Makefile.in: Regenerated.
673 1999-09-21 Jim Blandy <jimb@savonarola.red-bean.com>
675 * backtrace.c: #include "_scm.h" before testing whether
676 HAVE_UNISTD_H is #defined.
678 1999-09-20 Jim Blandy <jimb@savonarola.red-bean.com>
680 * read.c (scm_read): Don't assume that scm_cur_inp is always open.
681 * ports.c (scm_read_char): Same.
682 * ioext.c (scm_read_line): Same.
683 (Thanks to Bernard Urban.)
685 1999-09-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
687 * vectors.c (scm_vector_move_right_x): Bugfix: Remove side effect
689 numbers.c: Removed #ifndef SCM_RECKLESS at places where type
690 checking may invoke a generic. (Thanks to Michael Livshin.)
692 * __scm.h (SCM_WTA_DISPATCH_0, SCM_GASSERT0): New macros.
694 * numbers.c (scm_max, scm_min, scm_sum, scm_difference,
695 scm_product, scm_divide): Bugfix: Don't pass SCM_UNDEFINED to the
696 generic function if the asubr is called with only one arg.
698 1999-09-20 Gary Houston <ghouston@freewire.co.uk>
700 * scmsigs.c (scm_sigaction): add SA_RESTART to flags only if
701 HAVE_RESTARTABLE_SYSCALLS.
702 (scm_init_scmsigs): use siginterrupt if it's available. not
703 everyone who has restartable syscalls has SA_RESTART it seems.
705 (scm_sigaction): use scm_num2long/scm_long2num when converting
706 SIG_DFL/SIG_IGN, in case it doesn't fit in an INUM. use
707 scm_integer_p to test the type.
709 1999-09-18 Gary Houston <ghouston@freewire.co.uk>
711 * _scm.h, scmsigs.c: replace HAVE_RESTARTS with
712 HAVE_RESTARTABLE_SYSCALLS.
714 * strports.c (scm_strport_to_string): create the string from
715 pt->read_buf instead of an expression that evaluates to the
718 * gdbint.c (gdb_print): don't just use SCM_CHARS to get a C string
719 from the port: the port's buffer may not be NUL terminated.
721 1999-09-16 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
723 * Makefile.am (.c.x): Added missing semicolon after `false'.
725 1999-09-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
727 * print.c (scm_iprin1): Turn `write' and `display' into
728 primitive generics and use their associated generic functions in
729 scm_iprin1 for GOOPS objects.
731 * backtrace.c: #include <unistd.h> if present.
733 1999-09-14 Jim Blandy <jimb@savonarola.red-bean.com>
735 * Makefile.am (.c.x): Don't create a subshell just to delete the
736 .x file and return false.
737 * Makefile.in: Regenerated.
739 1999-09-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
741 * feature.c (scm_create_hook): New function. Replaces
742 scm_make_named_hook which is now deprecated.
743 (scm_make_hook_with_name): New primitive.
744 (print_hook): Hooks now print in a fancy way.
746 1999-09-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
748 * __scm.h, backtrace.c, backtrace.h, debug.c, debug.h, dynl-dld.c,
749 dynwind.c, dynwind.h, eval.h, evalext.c, evalext.h, feature.c,
750 feature.h, hashtab.c, hashtab.h, objects.c, objects.h, print.c,
751 procs.c, procs.h, smob.c, smob.h, srcprop.c, strorder.c, struct.c,
752 struct.h: Updated copyright notices.
754 * srcprop.c (scm_source_property): Bugfix: Use SCM_NECONSP instead
755 of SCM_NCONSP. (Thanks to Greg Badros.)
757 * gsubr.c (scm_make_gsubr): Use scm_make_subr_opt for creation of
760 * eval.c, debug.h (SCM_BACKTRACE_WIDTH): New debug option: width.
762 * backtrace.c: Keep backtraces within specified width by
763 adaptively adjusting fancy printing parameters and cut output if
765 (scm_display_application): Check args.
767 1999-09-11 Jim Blandy <jimb@savonarola.red-bean.com>
769 Change the name of the objects returned by OPENDIR from
770 "directory" to "directory stream". A predicate named "directory?"
772 * filesys.c (scm_directory_stream_p): Renamed from scm_directory_p.
773 At the Scheme level, "directory?" -> "directory-stream?".
774 (scm_dir_print): Use the phrase "directory stream" in printed form.
775 * filesys.h (scm_directory_stream_p): Prototype renamed
778 * Makefile.am (CLEANFILES): Remove versiondat.h; that should only
779 be removed by `make distclean', since it's generated by configure.
780 * Makefile.in: Regenerated.
781 (Thanks to Robert Bihlmeyer.)
783 * strop.c (scm_substring_move_x): Signal an error if start1
784 doesn't come before end1. (Thanks to Karoly Lorentey).
786 * numbers.c (scm_istr2flo): Don't call SCM_INEXP without first
787 calling SCM_NIMP. (Thanks to Karoly Lorentey).
789 * version.c (scm_libguile_config_stamp): Deleted. See
790 corresponding change to ../ice-9/boot-9.scm.
791 * versiondat.h.in: Remove definition for GUILE_STAMP.
792 * version.h: Delete prototype.
793 * Makefile.in: Regenerated.
795 1999-09-11 Gary Houston <ghouston@easynet.co.uk>
797 * filesys.c (scm_directory_p): new procedure "directory?" Returns
798 a boolean indicating whether its argument is a directory
799 port as returned by opendir (thanks to Dirk Herrmann for the
802 1999-09-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
804 * backtrace.c (display_frame_expr): Don't print a newline.
805 (display_frame): Print the newline here instead.
806 (display_backtrace_body): Don't print "Backtrace:".
807 (scm_backtrace): Print "Backtrace:" here instead.
809 1999-09-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
811 * procs.c (scm_setter): Signal WTA if handed an entity or operator
814 * feature.c, feature.h: (scm_hook_p, scm_hook_empty_p): New
815 primitives. (Thanks to Greg Badros);
816 (scm_hook_to_list): New primitive; Hooks are now smobs.
818 1999-09-08 Gary Houston <ghouston@easynet.co.uk>
820 * stime.c (bdtime2c): rewrite the ASSERTs. Accept a value
821 of #f for the 10th vector element to avoid an exception
822 seen by Bernard Urban.
823 (scm_mktime): unneeded ASSERT removed.
825 1999-09-07 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
827 * eval.c (scm_map, scm_for_each): Converted to dispatch on generic
830 * __scm.h (SCM_WTA_DISPATCH_n, SCM_GASSERTn): New macros.
832 1999-09-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
834 * numbers.c: Converted comparison operations to dispatch on
835 generic if args don't match.
837 * Makefile.am (ETAGS_ARGS): Added support for GPROC and GPROC1.
839 1999-09-06 James Blandy <jimb@mule.m17n.org>
841 * guile-snarf.c: Deleted. Snarfing should respect CPP
842 conditionals, so it needs to actually run CPP. Bleah.
844 1999-09-05 James Blandy <jimb@mule.m17n.org>
846 Handle errors properly in guile-snarf. (Thanks to Han-Wen Nienhuys.)
847 * guile-snarf.in: Be sure to exit with an error if CPP does.
848 * Makefile.am (.c.x): Delete the .x file and exit with an error
849 status if guile-snarf exits with an error status.
850 * Makefile.in: Regenerated.
852 * snarf.h (SCM_GLOBAL_KEYWORD): Call scm_c_make_keyword, not
853 scm_makekey, which doesn't exist any more. Guess nobody's using
856 * guile-snarf.c: New implementation of guile-snarf, meant to be
857 more robust than the shell script. I think it's complete, but I
858 haven't tested it at all, and I haven't changed the build process
859 to actually use it. We should compare its output against that of
860 the existing shell script, for all source files.
862 * guile-snarf.c (parse_args): Abort if we haven't handled some
865 1999-09-03 James Blandy <jimb@mule.m17n.org>
867 * load.c (scm_search_path): If the filename has any extension at
868 all, ignore the entire list of extensions. Also, don't check whether
869 the file is accessible. If the file exists, accessible or not, we
870 should return it. Inaccessible files should cause an error later.
871 (Thanks to Keisuke Nishida for the suggestions.)
873 1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
875 * gc.c (cleanup, scm_init_storage): Use on_exit if present and
876 atexit not available. (sunos4.1.4 needs it.)
878 1999-09-01 James Blandy <jimb@mule.m17n.org>
880 I take it all back --- bcopy does handle overlapping source and
881 destination areas correctly. At least on every system I could
882 find. But it is better to use AC_REPLACE_FUNCS than to introduce
883 new CPP conditionals.
884 * memmove.c: New file, implementing memmove in terms of bcopy.
885 * scmconfig.h.in: Regenerated.
887 Allocators should use the `void *' type for generic pointers.
888 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
889 argument and return types.
890 * gc.h: Corresponding changes to prototypes.
893 1999-08-31 James Blandy <jimb@mule.m17n.org>
895 * numbers.c (scm_init_numbers): Claim to support the `complex'
896 feature, as expected by (ice-9 format). (Thanks to Ceri Storey.)
898 * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
899 find (ice-9 boot-9) when Guile was compiled in a separate
900 directory from the source. (Thanks to Rodney Brown.)
901 * Makefile.in: Regenerated.
903 * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply
904 table lengths by the size of a single element when growing the
905 table. (Thanks to Bill Schottstaedt.)
907 1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
909 * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
910 SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
911 since that cuts down the time for type dispatch by 50%.
913 1999-08-30 James Blandy <jimb@mule.m17n.org>
915 * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
916 not a correct substitute for memmove, because it doesn't handle
917 overlapping source and destination areas on many platforms.
918 Overlaps are the primary reason to use memmove in the first place.
919 * ports.c (scm_ungetc): Same.
920 * strop.c (scm_substring_move_x): Same.
922 1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
924 * gc.c (scm_init_storage): Skip registration of cleanup on systems
925 which lack atexit. (Is it important that cleanup is made
926 properly? Maybe we should replace all `exit' with `scm_exit' and
929 * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
930 scm_struct_free_standard, scm_struct_free_entity): Declared to
931 return scm_sizet instead of size_t.
933 * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined
934 there on sunos4.1.4.)
936 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
938 * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
939 Account for the case when second argument is unbound.
941 * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
942 (Thanks to Karoly Lorentey.)
944 * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
945 isn't present. (Thanks to Suzuki Toshiya.)
947 * ports.c: Use ANSI C prototypes in definitions. (Thanks to
950 * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
953 * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
954 Bernard Urban and Ian Grant.)
956 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
957 again. (1.3.4 will be binary incompatible with 1.3.2 because of a
958 change in the representation of entities and operators.)
960 1999-08-29 Gary Houston <ghouston@easynet.co.uk>
962 * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
963 don't allocate zero bytes (thanks to Bill Schottstaedt).
965 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
967 * procs.c (scm_setter): Converted to use generic dispatch.
969 * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
972 * load.c (scm_search_path): Don't try extensions which already are
973 present at the end of the filename.
974 (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
976 * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
978 Cleanup and simplification of generic method dispatch.
979 Also, the quadruple representation of entity and operator
980 procedures has been replaced with single.
982 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
984 * print.c (scm_isymnames): Removed #@hash-dispatch.
986 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
987 from eval.c; Support 0 arity methods.
988 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
989 (scm_apply_generic_env): Removed.
990 Replaced slots proc0-3 with procedure.
992 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
993 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
994 SCM_OPERATOR_PROCEDURE.
995 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
996 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
998 * struct.c, struct.h: Replace 4 procedure slots with one.
999 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
1001 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
1004 * eval.c (scm_sym_args): Removed.
1005 (SCM_CEVAL): Simplified entity application.
1006 Moved dispatch code to objects.c.
1008 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
1010 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1012 * sort.c (closureless): Use scm_eval_body.
1014 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
1015 with a symbol as last form was first called normally and then via
1016 `map' or some other mechanism using primitive apply, an ILOC was
1019 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1021 This change extends the representation of primitive procedures
1022 with more data fields, e.g. a place for documentation and true
1023 procedure properties.
1025 * procs.c, procs.h (scm_subr_entry): New type: Stores data
1026 associated with subrs.
1027 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
1028 SCM_SUBR_DOC): New macros.
1029 (scm_subr_table): New variable.
1030 (scm_mark_subr_table): New function.
1032 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
1034 * gc.c (scm_gc_mark): Don't mark subr names here.
1035 (scm_igc): Call scm_mark_subr_table.
1038 This change implements a scheme for letting a generic work as a
1039 shadow for a primitive procedure. If the primitive procedure
1040 can't dispatch on its arguments, control is left over to the
1041 generic. Normal wrong type arg errors will be generated until the
1042 user has hung the first method on the primitive.
1044 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
1046 * procs.c, procs.h (scm_subr_p): New function (used internally).
1048 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
1050 * objects.c, objects.h (scm_primitive_generic): New class.
1052 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
1054 * print.c (scm_iprin1): Print primitive-generics.
1056 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
1057 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
1059 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
1060 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
1061 primitives). NOTE: This means that it is now *required* to use
1062 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
1063 obscured representation that will be removed in the future anyway,
1064 so backward compatibility is no problem here).
1066 * numbers.c: Converted most numeric primitives (all but bit
1067 comparison operations and bit operations) to dispatch on generic
1068 if args don't match.
1071 Better support for applying generic functions.
1073 * eval.c, eval.h (scm_eval_body): New function.
1075 * objects.c (scm_call_generic_0, scm_call_generic_1,
1076 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
1080 Optimization of the generic function dispatch mechanism.
1082 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
1083 called scm_memoize_method instead of doing a second lookup.
1085 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
1090 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
1091 scm_sysintern so that the binding connected with the subr name
1092 isn't cleared when we give set = 0.
1095 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1097 More transparent handling of ports with print states.
1099 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
1100 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
1101 instead of a pair of a port and a print state. We'll need to cons
1102 once extra in scm_printer_apply but the type system will be
1103 cleaner, it will mix better with GOOPS, and, it will be even more
1104 transparent to the user.
1106 * print.c (scm_get_print_state): New procedure: Given an output
1107 port, return the print state associated to it in the current print
1108 chain, if one exists;
1109 (scm_port_with_print_state): New procedure: Associate a
1110 print-state with a port.
1111 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
1112 (scm_printer_apply): Wrap port and pstate as a smob;
1113 (print_state_printer): Removed.
1115 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
1117 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
1120 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
1121 testing (otherwise the port-print-state trick won't be transparent
1122 to the user; one example where this caused problems was in the
1123 (ice-9 format) module).
1125 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1127 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
1128 SCM_UNSPECIFIED instead of the set value.
1130 1999-08-20 James Blandy <jimb@mule.m17n.org>
1132 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
1134 * ports.h (enum scm_port_rw_active): New enum, containing
1135 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
1136 zero). The debugger knows about enums, but doesn't know about
1138 (typedef scm_port): Declare rw_active member to be an enum
1140 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
1142 * ports.c (scm_add_to_port_table): Same.
1143 * strports.c (st_flush, st_end_input): Same.
1145 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
1146 scm_must_realloc, and scm_done_malloc as appropriate.
1148 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1150 * sort.c (quicksort): Added condition to protect the algorithm
1151 from crashing the interpreter if the less predicate is buggy.
1153 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
1155 * fports.c (fport_write): fix line-buffering mode again.
1156 (scm_open_file): recognise 'l' for line-buffering.
1157 (scm_setvbuf): recognise _IOLBF for line-buffering.
1159 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1161 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
1164 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
1165 evaluating closures.
1167 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
1169 * fports.c (fport_write): use memcpy instead of strncpy, in case
1170 the data contains NUL.
1172 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1174 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
1176 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
1177 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
1178 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
1179 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
1180 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
1181 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
1182 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
1183 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
1184 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
1185 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
1186 scm_sym_ as prefix for symbols.
1188 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
1190 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
1191 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
1192 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
1193 scm_sym_atcall_cc): Made global.
1195 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1197 * eval.c (scm_sym_args): Made global.
1199 * objects.c (scm_set_object_procedure_x): Disallow setting of
1200 procedures for pure generic functions.
1202 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
1204 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
1205 Scheme name from lseek to seek, but lseek was added recently so
1206 it shouldn't be a big problem.
1207 * ports.c, gdbint.c, ioext.c: changed callers.
1209 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
1211 * fports.c (fport_input_waiting): if select is used, return 1
1212 instead of whatever FD_ISSET expands to. maybe it will be useful
1213 to interpret the value from the input_waiting ptob procedure as a
1214 lower bound on the number of bytes available.
1216 * Mikael asked for a few names to be changed...
1218 * ports.c (scm_make_port_type): take the write procedure as the
1219 second argument instead of the flush procedure.
1220 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
1221 fflush -> flush, read_flush -> end_input, fclose -> close,
1222 fill_buffer -> fill_input, ftruncate -> truncate,
1223 input_waiting_p -> input_waiting.
1225 * ports.c (end_input_void_port): was read_flush_void_port.
1226 (scm_set_port_end_input): was scm_set_port_flush_input.
1227 (scm_set_port_flush): was scm_set_port_write.
1228 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
1229 (scm_end_input): was scm_read_flush.
1230 (scm_fill_input): was scm_fill_buffer.
1231 (scm_flush): was scm_fflush.
1232 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
1233 (fport_end_input): was local_read_flush.
1234 (fport_flush): was local_fflush.
1235 (fport_close): was local_fclose.
1236 (fport_truncate): was local_ftruncate.
1237 (fport_seek): was local_seek.
1238 (fport_free): was local_free.
1239 (fport_fill_input): was fport_fill_buffer.
1240 * strports.c (st_end_input): was st_read_flush.
1241 (st_truncate): was st_ftruncate.
1242 * vports.c: (sf_flush): was sfflush.
1243 (sf_close): was sfclose.
1244 (sf_fill_input): was sf_fill_buffer.
1246 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
1249 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1251 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
1252 forms now contain the expressions to be dispatched upon instead of
1253 depending on a surrounding lambda or let; Generic function
1254 dispatch has been optimized; `apply' on a generic function now
1255 works a little bit strangely. It uses a trick so that the type
1256 dispatch code in SCM_CEVAL can be reused.
1258 * objects.h, objects.c (scm_apply_generic_env): Added (used by
1260 (scm_operator_p): Added.
1261 (scm_sym_atdispatch): Added.
1262 (scm_set_object_procedure_x): Modified to handle the new style
1264 (scm_object_procedures): New debugging procedure.
1266 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1268 * eval.c, eval.h (scm_sym_args): Added.
1270 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
1272 * feature.c, feature.h (scm_c_run_hook): Added.
1274 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
1275 cdrxnoap and loopnoap instead of begin and loop.
1277 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
1279 * ports.c (scm_putc, scm_puts),
1280 * unif.c (scm_uniform_array_write): use scm_lfwrite.
1281 * ports.c (scm_putc): change type of first argument from int to char.
1283 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1285 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
1286 SCM_IM_HASH_DISPATCH.
1288 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
1289 (scm_si_redfined, scm_si_hashsets): Moved.
1291 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
1292 flag which combines type and status info so that the class
1293 redefinition protocol has zero cost during normal execution.
1295 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
1297 * ports.h (scm_ptob_descriptor): include a write procedure again.
1298 it's more efficient for unbuffered fports (e.g., sockets.)
1300 * ports.c (scm_puts): use ptob->write.
1301 * vports.c (scm_make_sfptob): set write proc in ptob.
1302 * strports.c (scm_make_stptob): set write proc in ptob.
1303 * ports.c (write_void_port): new procedure.
1304 * vports.c (sf_write): new procedure.
1305 * ports.c (scm_lfwrite): use ptob->write.
1306 * strports.c (st_write): new procedure.
1307 * fports.c (fport_write): new procedure.
1308 (scm_make_fptob): set write in ptob to fport_write.
1309 * ports.h: prototype for scm_set_port_write.
1310 * ports.c (scm_make_port_type): initialise ptob write procedure.
1311 (scm_set_port_write): new proc.
1313 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
1315 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
1316 until we've verified that it is actually a port. (Thanks to
1319 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1321 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
1322 code, particularly an unnecessary test (len != size, where len ==
1323 size). (Was this leftovers from debugging code, or have I missed
1324 something profound?)
1326 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
1327 size. (Thanks to James Dean Palmer.)
1329 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
1330 (Thanks to Lorentey Karoly.)
1332 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1334 * eval.c (scm_m_expand_body): Use scm_cons_source.
1336 * struct.c (scm_print_struct): Use vtable name.
1338 * print.c (scm_init_print): Set name of print state type.
1340 * stacks.c (scm_init_stacks): Set name of stack type.
1342 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1344 * eval.c (SCM_CEVAL): Removed old implementation of internal
1347 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
1349 * debug.c, debug.h (scm_reverse_lookup): Added.
1350 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
1351 internal procedure definitions; Don't use scm_i_inner_name.
1353 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
1354 New isym operations.
1356 * eval.h: Added prototypes for multi language support functions.
1358 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
1359 improper lists in the low-level representation, since that will
1360 cause a begin to be prepended at macro expansion.
1362 * eval.c (scm_cons_source): Version of cons which copies source
1363 properties from an existing cell.
1364 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
1366 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
1367 procedure source before calling scm_unmemocopy instead of faking
1370 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1372 Ported `internal defines' fix from SCM. Original ChangeLog entry:
1374 1998-07-09 Radey Shouman <radey@colorage.com>
1376 * eval.c (ceval_1): Modifications to allow rewriting of interal
1377 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
1378 body of which it is the CAR is macro expanded by m_expand_body,
1379 which rewrites internal DEFINE.
1381 (m_expand_body): Added.
1383 (m_macroexp1): Added argument to control error checking:
1384 m_expand_body may speculatively expand forms in the wrong
1385 environments. Made argument number checks conditional on
1388 (m_body): Added, error checks bodies and inserts the ISYM tokens.
1390 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
1393 (m_cond): (m_case): (m_quote): Modified to avoid destructively
1394 changing their argument forms. Since m_expand_body
1395 speculatively macro expands forms the process must be
1398 (m_ident_eqp): Fixed to use proper environment.
1400 (renamed_ident): Added DEFER_INTS_EGC.
1402 Added prototypes for static functions.
1408 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
1409 is false, do not produce an error for unbound variables, return a
1410 pointer to cell_undef instead.
1412 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
1416 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
1417 destructively changing their argument forms. Since m_expand_body
1418 speculatively macro expands forms the process must be reversible.
1420 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
1421 SCM_IM_LET introduced by named lets.
1423 (scm_m_letstar): Use scm_m_body instead of bodycheck.
1425 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
1426 scm_letrec. scm_letrec1 does not check for a null binding and
1427 takes an additional argument to specify the ISYM of the body. Use
1428 scm_m_body instead of bodycheck.
1430 (scm_m_let): Use scm_m_body instead of bodycheck.
1432 (scm_m_expand_body, scm_macroexp): New.
1434 (unmemocopy): Account for ISYMs introduced by scm_m_body.
1436 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
1437 check=1. Throw error for internal defined that have not been
1438 rewritten by scm_m_expand_body.
1440 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
1441 Removed prototype for SCM_APPLY.
1443 * tags.h: Added extern declaration of scm_isymnames.
1445 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1447 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
1449 * lang.c: New file: Beginning of multi-language support.
1451 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
1453 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
1454 (scm_dynamic_wind): Added argument checking for the after guard so
1455 that we don't add garbage on the dynwind chain.
1456 (scm_swap_bindings): Added.
1458 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
1459 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
1460 (scm_isymnames): New isyms for multi-language support.
1462 * eval.c (scm_nil, scm_t): New symbols.
1463 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
1464 forms for multi-language support.
1466 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1468 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
1470 Renamed functions in the random function library interface
1471 from scm_i_XXX --> scm_c_XXX.
1473 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
1475 * ports.c (scm_putc): fix line-buffering.
1477 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1479 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
1480 scm_set_ptob_XXX --> scm_set_port_XXX.
1482 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1484 * ports.c, ports.h (scm_make_port_type): New interface for
1485 creation of port types (replaces scm_newptob). Just as for the
1486 smobs, we need to separate the internal representation of smob
1487 types from the interface, so that we easily can add new fields and
1488 rearrange things without caring about backward compatibility.
1489 This change was forced by the need in GOOPS to create classes
1490 representing port types.
1491 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
1492 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
1493 scm_set_ptob_seek, scm_set_ptob_truncate,
1494 scm_set_ptob_input_waiting_p): New setters.
1495 (scm_newptob): Rewritten to use scm_make_port_type. For backward
1497 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
1498 (scm_prinport): Removed.
1499 (scm_port_print): Added.
1500 (scm_print_port_mode): Added.
1501 (void_port_ptob, print_void_port, close_void_port, noop0):
1502 Removed. Removed #include "genio.h" Added #include "objects.h",
1505 * fports.c (prinfport): Moved code from ports.c.
1506 (local_free): Added.
1507 (scm_fptob): Removed. Instead use new interface.
1508 (scm_make_fptob): Added. (Need to create basic ports in a
1509 specific order in ports.c.)
1511 * strports.c (scm_stptob, prinstpt, noop0): Removed
1512 (scm_make_stptob): Added.
1514 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
1515 (scm_make_sfport): Added.
1517 * filesys.c (scm_dir_print): Don't use the port printing code.
1518 Instead provide specific directory printer.
1520 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
1522 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
1523 scm_ptob_descriptor.
1525 * smob.c (scm_smob_print): Handle non-existing type name nicely.
1526 Removed #include "genio.h"
1528 * objects.c (scm_make_port_classes): New function ptr.
1530 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
1532 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
1534 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
1535 allow the 1st argument to be a fdes or filename as well as a
1536 port (as in the filesys.c version).
1538 * filesys.c (scm_truncate_file): removed.
1540 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1542 * readline.c, readline.h: Removed.
1544 * objects.c, objects.h (scm_port_class): Added.
1545 (scm_class_of): Look up port class in scm_port_class.
1546 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
1547 SCM_INOUT_PCLASS_INDEX): Added.
1550 * Makefile.am: Removed genio.c, genio.x.
1554 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1556 * init.c: Make sure that scm_post_boot_init_modules is called only
1557 once. (Important when using a dumped image.; Thanks to Bernard
1560 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
1562 * guardians.c (scm_guardian_zombify): Separate scanning for
1563 zombies from marking the pairs of the free list.
1565 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
1566 use the macros. (Thanks to Michael Livshin.)
1568 * eval.c (scm_m_lambda): Let bodycheck check the body of the
1569 lambda. Let your sins be purified by the blood of the lambda.
1570 (Thanks to Eric Hanchrow.)
1572 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
1573 (Thanks to Valdis Kletnieks.)
1575 Fixes for EMX from Mikael Ståldal.
1577 * filesys.c: #include <io.h>, if we have it.
1578 * scmconfig.h.in: Regenerated.
1580 * stime.c (ftime): Delete declaration for this function --- let
1581 the system supply it.
1583 Cleanups from John Bley.
1585 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
1587 * gsubr.c: Don't include "gsubr.h" twice.
1589 Cleanups for compilation on Irix 6, from David Kaelbling.
1591 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
1592 regex_t pointer. This is what the callers have, mostly.
1593 (scm_regexp_exec): Don't forget to pass the `rx' argument to
1594 scm_regexp_error_msg.
1596 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
1597 int. That way, if we get a warning on this line, it's more likely
1598 that we're really missing bits we care about.
1600 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
1603 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
1604 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
1605 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
1606 cast at all is more appropriate in every case. At the moment, we
1607 assume everywhere that SCM is an integral type anyway.
1609 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
1611 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
1612 read_pos after scm_fill_buffer.
1614 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
1617 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
1618 fports.c (fport_fill_buffer): implement the interface change.
1620 * ports.c (scm_fill_buffer): interface change: no longer increments
1621 read_pos past the character that's returned. it seems clearer to
1622 leave it to the caller to decide what to do (thanks Jim).
1624 * vports.c (sf_fill_buffer): put the read char into the buffer
1625 as well as returning it.
1627 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure

1632 * strports.c (scm_strprint_obj): simplify. start with initial
1634 (st_seek): don't allow string to be extended if seeking past
1635 the end of a read-only port.
1637 1999-07-12 Gary Houston <ghouston@easynet.co.uk>
1639 * strports.c (st_seek): change the resize checks.
1641 * ports.c (scm_ftruncate): throw error if offset works out negative.
1643 * strports.c (st_flush): increase string size in blocks of
1644 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
1645 it's greater and reset read_buf_size.
1646 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
1647 to be maintained for output ports too (it holds the written
1648 part of the string, while write_buf may have unwritten buffer
1650 (st_truncate): rewritten.
1651 (top of file): added a few notes.
1653 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
1655 Patch from Greg Badros:
1656 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
1657 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
1658 (function pointer) argument to scm_make_gsubr and scm_make_subr
1659 calls. This avoids warnings in C++ programs using guile-snarf.
1661 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
1663 * strports.c (st_grow_port): set pt->read_pos. set
1664 pt->read_buf_size one less than pt->write_buf_size if there's
1665 an unwritten char at the end of the string. similarly for
1667 (st_resize_port): renamed from st_grow_port.
1668 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
1669 seek from read_end instead of write_end for SEEK_END.
1670 (st_ftruncate): calculate current length using readbuf, not write
1672 (scm_strport_to_string): use read_buf_size for length.
1673 (stfill_buffer): don't re-initialise the readbuf.

1682 1999-07-08 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1684 * symbols.c (scm_gensym): Bugfix. (Thanks to Johannes Hjorth.)

1688 * smob.c: added scm_make_smob_type_mfpe (), scm_set_smob_mfpe ();
1689 use scm_make_smob_type_mfpe to initialize "free", "flo", "bigpos",
1690 and "bigneg" smob types.
1692 * smob.h: Add do ... while(0) idiom to SCM_NEWSMOB. Added
1693 SCM_RETURN_NEWSMOB macro. Added protos for new functions in
1696 * *.c: Use scm_make_smob_type_mfpe, instead of scm_newsmob, and
1697 use SCM_NEWSMOB or SCM_RETURN_NEWSMOB in constructors instead of
1698 SCM_NEWCELL and setting the CAR/CDR by hand.

1721 * ports.c (scm_read_flush): new procedure, resets the putback
1722 buffer before calling the ptob routine.
1724 * strports.c (scm_strprint_obj): bug fix: get pt from the port,

1781 * dynl-dl.c (sysdep_dynl_link): Added parenthesis around the
1782 trinary conditional in order for the flag computation to be
1785 1999-06-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1787 * struct.c, struct.h:
1789 In order to support different kinds of deallocation, a destructor
1790 slot has been added to struct vtables. This allows for structs
1791 containing pointers to other memory blocks.
1793 (scm_struct_i_free): New hidden struct slot. Holds destructor for
1794 instances to this vtable.
1795 (scm_struct_free_0): New destructor: Doesn't deallocate data.

1807 scm_struct_i_size which holds the size of light structs.
1808 (scm_struct_i_n_words): This slot has changed meaning. Previously

1810 (scm_alloc_struct): Clear flags.
1811 (SCM_STRUCTF_MASK): 4 new flag positions added => 12 bits.
1813 (struct_num, scm_struct_i_tag): Removed.

1862 1999-06-19 Jim Blandy <jimb@savonarola.red-bean.com>
1864 Patch from Greg Harvey:
1865 * eq.c, eval.c, list.c, ramap.c, vectors.c: Always write parens
1866 around the condition of an `if', `while', etc., even if the
1867 condition is a macro invocation that expands to something
1868 surrounded by parens. It's more readable.
1870 * eval.c (scm_map, scm_for_each): Verify that all arguments are
1871 proper lists, and of the appropriate lengths.
1872 (check_map_args): New function. (Thanks to Greg Harvey for the
1875 1999-06-19 Michael Livshin <mike@olan.com>
1877 * guardians.c (guardian_t): `next' - new field to be used for
1878 chaining the live guardians in a single-linked list during the GC
1880 (GUARDIAN_NEXT): convenience macro to access the `next' field.
1881 (guardians, guardians_size, n_guardians): deleted.

1894 (scm_igc): Check for underflow by seeing if this is negative.
1896 * gc.h (scm_mallocated): Fix declaration.
1897 (Thanks to Greg Harvey.)
1899 * ports.h: #include <sys/types.h>, to get a definition for `off_t'.

1908 vector contents, to be used only during garbage collection.
1909 * weaks.h (SCM_WVECT_GC_CHAIN): New macro to access it.
1910 * gc.c (scm_weak_vectors): Now a SCM instead of a SCM*, and now
1912 (scm_weak_size, scm_n_weak): Deleted.
1913 (scm_igc): Use SCM_WVECT_GC_CHAIN to build up a chain of weak
1914 vectors without allocating new storage during GC, using
1915 scm_weak_vectors as the head of the chain.
1916 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
1917 instead of stepping through an array.
1918 (scm_gc_sweep): Update offset used to find start of weak vector to
1920 (scm_init_storage): Set scm_weak_vectors to EOL.
1922 Fix from Ken Raeburn <raeburn@raeburn.org>:
1923 * gc.c (already_in_gc): New variable.
1924 (scm_igc): Set and clear already_in_gc; abort if it's set at
1927 1999-06-14 Jim Blandy <jimb@savonarola.red-bean.com>
1929 Fix from Gary Houston:
1930 * fports.c (local_seek): Signal an error if the seek fails.
1931 * ports.c (scm_lseek): Don't check return value of port's seek
1932 function; it's its job to signal an error if there's a problem.
1934 1999-06-12 Jim Blandy <jimb@savonarola.red-bean.com>
1936 * strports.c (scm_call_with_output_string): Don't include the

1941 * fports.c, fports.h, gc.c, gdbint.c, ioext.c, ports.c, ports.h,
1942 scmsigs.c, strports.c, vports.c: Install the sources which
1943 actually correspond to the changes described below. I got the
1944 ChangeLog entries and the patch from two different places...
1946 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
1948 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
1949 it shows up as terrible performance, as we GC constantly.
1951 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
1952 newline. A bit faster, and definitely hairier.
1953 (scm_read_line): Count newlines here instead.
1955 * strings.c (scm_take_str): New function.
1956 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h
1957 (scm_take_str): New declaration. * ioext.c (scm_read_line): Use

1962 * init.c (scm_init_standard_ports): Request line-buffering on
1963 the standard output port.
1964 * ports.c (scm_mode_bits): Recognize 'l' as a request for line
1966 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
1967 and there's a newline to be written, flush the port.
1969 Gary Houston's open-buffer port patches:
1971 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
1973 * ports.c: (scm_lseek): clear buffers even if just reading current

1989 ports.c (scm_newptob): set ftruncate.
1991 ports.c (scm_ftruncate): new procedure.
1992 fports.c (local_ftrunate), strports.c (str_ftruncate): new procs.

1994 fports.h (scm_port): change size types from int to off_t.
1995 ports.c (scm_init_ports): initialise the seek symbols here
1996 instead of in ioext.c.
1997 strports.c (scm_call_with_output_string): start with an empty
1998 string, so seek and ftruncate can be used.
2000 gdbint.c: adjust string port usage.
2002 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
2004 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
2005 equivalent to fflush for the read buffer.
2006 * ports.c (scm_newptob): set read_flush.
2007 ports.c (void_port_ptob): set read_flush.
2008 fports.c (local_read_flush): new proc. add to ptob.
2009 strport.c (st_read_flush): likewise.
2010 vport.c (sf_read_flush): likewise.
2011 fports.h (struct scm_fport): remove random member. there's nothing
2012 left but fdes. leaving it as a struct to allow for future changes.
2013 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
2014 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
2015 ptob proc if the read buffer is filled.
2017 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
2019 * ports.h (scm_port): add a rw_random member and replace
2020 reading and writing members with rw_active member.
2021 SCM_PORT_READ/SCM_PORT_WRITE: new values.
2023 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
2025 * ports.h (struct scm_port_table): add writing and reading members
2026 to replace write_needs_seek: it isn't good enough for non-fports.
2027 ports.c, ioext.c, fports.c: corresponding changes.
2028 (struct scm_port_table): give it a typedef and rename to scm_port.
2029 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
2030 corresponding changes.
2032 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
2034 * ports.c (scm_newptob): bugfix: set seek member.
2035 * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
2036 and generalised to all port types.
2038 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
2040 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
2041 signals (it was only being done for handlers installed from Scheme).
2042 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
2043 waiting for input caused an EINTR error from read.
2045 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
2047 * ports.h (struct scm_port_table): make all the char members
2048 unsigned, so they convert to int without becoming negative if large.
2050 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
2052 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
2053 with threads enabled. rename this procedure to
2054 fport_wait_for_input and take a port instead of a fdes.
2055 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
2057 * readline.c (scm_readline): Applied a patch from Greg Harvey to
2058 get readline support working again: use fdopen to get FILE objects.
2060 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
2062 * gc.c (scm_init_storage): install an atexit proc to flush the
2064 (cleanup): the new proc. it sets a global variable which can be
2065 checked by the ptob flush procs to avoid trying to throw
2066 exceptions during exit. not very pleasant but it seems more reliable.
2067 * fports.c (local_fflush): check terminating variable and if set
2068 don't throw exception.
2069 * CHECKME: that the atexit proc is installed if unexec used.
2071 * throw.c (scm_handle_by_message): don't flush all ports here.
2072 it still causes bus errors.
2074 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
2075 and move to ioext.c.
2077 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
2079 * ports.c (scm_char_ready_p): check the port buffer and call the
2080 ptob entry if needed.
2082 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
2083 ptob initialisers. use it in char-ready
2085 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
2087 * vports.c (sfflush): modified to write a char (since softports

2112 pointer (and probably vice versa but who knows.)

2115 (scm_puts): rewritten
2116 * fports.c (local_ffwrite, local_fputs): removed.

2153 * ports.h: fport buffer moved into port table: to be
2154 used for all port types.

2347 1999-05-09 Jim Blandy <jimb@savonarola.red-bean.com>
2349 * strop.c (scm_string_capitalize_x): Use the SCM object `s' in
2350 error messages, not the uninitialized string `str'. Love that
2353 * strop.c (scm_substring_move_x): New function, which can handle
2354 arbitrary overlapping substrings.
2355 (substring-move-left!, substring-move-right!): These are
2356 now just synonyms for substring-move!.
2357 * strop.h (scm_substring_move_x): New prototype.
2358 (scm_substring_move_left_x, scm_substring_move_right_x):
2359 #define these as synonyms for scm_substring_move_x.

2413 * scmconfig.h.in: Regenerated.
2415 * numbers.c (s_bignum): Renamed to s_bignum, and made static.
2416 Libguile should not be exporting random little strings.

2419 More const changes from Ken Raeburn.
2420 * numbers.c (scm_s_bignum, fx): Now const.

2427 linking crashes on NetBSD. (Thanks to Ken Raeburn.)
2429 1999-03-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2431 * numbers.c (isfinite): Define this macro if not defined: Return a
2432 non-zero value if X is finite. (From ISO C 9x standard.)
2433 (scm_inexact_to_exact): Bugfix: Don't pass NaNs to scm_dbl2big.
2434 (Thanks to Jon Trowbridge and Greg Harvey.)
2436 1999-03-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

2461 (scm_system_module_env_p): Assume root environment is no lookup
2464 * debug.c, eval.c, evalext.c, gdbint.c stacks.c:
2465 #include "modules.h".
2467 * modules.c, modules.h, eval.c, eval.h (scm_env_top_level,

2474 * error.c (scm_wta): Pass SCM_LIST1 (arg) instead of SCM_EOL to
2475 scm_misc_error when pos is a string. This allows for dispatching
2476 arbitrary error messages with one argument via SCM_ASSERT:

2479 1999-03-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

2485 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2487 Most of this batch of changes is about how to deal with extended
2488 types when an object system is loaded into Guile. A nice object
2489 system is capable of representing Guile's types as class objects.
2491 For example, we want a regular expression to be of class <regex>.
2492 But regular expressions are smobs which aren't under direct
2493 control of the object system, so there has to be some mechanism
2494 which informs the object system that a new class should be created
2495 which can represent the smob type. I call this a "wrapper class".
2497 * objects.c: #include "smob.h";
2498 (scm_class_keyword): Removed. (Class is automatically created by
2500 (scm_smob_class): Array of smob classes indexed by smobnum.
2501 (scm_make_extended_class): "Plugin" function pointer for creation
2502 of wrapper classes for smob and struct types.
2503 (scm_class_of): Handle compiled closures. (Currently regarded as
2505 Use scm_smob_class to handle smob types;
2506 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
2507 through scm_smob_class;
2510 * smob.c (scm_newsmob): Also create a wrapper class if
2511 scm_smob_class has been initialized.
2513 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
2514 type code and smobnum.
2516 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
2517 (scm_struct_table): Weak key table with auxilliary information for
2518 struct types. Currently used for names and wrapper classes.
2519 (scm_struct_ihashq): Hash function for structs.
2520 (scm_struct_create_handle): Get/create entry in scm_struct_table.
2521 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
2522 for accessing names of vtables. The record implementation in
2523 boot-9.scm currently uses the setter to record the name of record
2524 types. When the object system is initialized, it can use this
2525 information to create wrapper classes with suitable names.
2526 (scm_init_struct): Allocate scm_struct_table.
2527 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
2528 (struct tags are a finite resource and we might want to restrict
2529 the use of tags to vtables only. E.g., Goops only uses tags for
2531 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
2533 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
2536 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
2537 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
2538 Used for access of struct table entries.
2540 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
2541 (scm_hash_fold): New procedure. Used to process all entries in a
2542 hash table (in no particular order).
2544 Argh! For the umpteenth time I got compilation errors because of
2545 the "intuitive" name `kw'. This has to have an end:
2547 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
2548 "kw" --> "keywords" everywhere.
2549 (I doubt that this will cause big compatibility problems since the
2550 application interface is unaffected.)
2552 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
2554 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2556 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
2557 column inums to native form.
2559 Improvement of backtraces: Introduces a new stack narrowing
2560 specifier, #t, for the inner cut. (See further in the comments in
2561 stacks.c:narrow_stack ().)
2563 * procprop.c, procprop.h (scm_sym_system_procedure): New symbol.
2564 (Used to flag certain system procedures which shouldn't turn up in
2567 * eval.c (scm_sym_system_module): New symbol. (Used to flag
2568 modules which aren't "user" modules and the code of which
2569 shouldn't turn up in backtraces.)

2572 Extract the lookup closure from an environment.
2573 (scm_system_module_env_p): New function: Return non-#f if MODULE
2576 * stacks.c: #include "eval.h"; #include "procprop.h";
2577 (narrow_stack): Handle new narrowing specifier #t.
2579 * debug.c (scm_procedure_name): Use name property in the default
2582 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
2584 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
2586 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
2587 procedure throughout.
2589 * print.c (scm_iprin1): Removed extraneous space when printing
2590 procedure-with-setters.
2592 Entity and operator setter slots were introduced as a complement
2593 to the <procedure-with-setter> type in order to support entities
2594 and operators with setters in a reasonable and efficient way.

2642 * readline.c (in_readline, reentry_barrier_mutex): Make these
2645 * readline.c: #include <sys/time.h> and "iselect.h", so we can

2701 SYMB now point to const.
2703 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2705 * print.c (scm_iprin1): Use scm_procedure_name instead of
2706 scm_procedure_property for compiled closures.
2708 * tags.h (scm_tc7_pws): New procedure type. Four representations
2709 for procedure-with-setters were considered before selecting this
2712 1. A closure where the CODE and ENV slots are used to represent
2713 the getter and a new SETTER slot is used for the setter. The
2714 original getter is stored as a `getter' procedure property. For
2715 closure getters, the CODE and ENV slots contains a copy of the
2716 getter's CODE and ENV slots. For subr getters, the CODE contains
2719 2. A compiled closure with a call to the getter in the cclo
2720 procedure. The getter and setter are stored in slots 1 and 2.
2722 3. An entity (i.e. a struct with an associated procedure) with a
2723 call to the getter in the entity procedure and the setter stored
2724 in slot 0. The original getter is stored in slot 1.
2726 4. A new primitive procedure type supported in the evaluator. The
2727 getter and setter are stored in a GETTER and SETTER slot. A call
2728 to this procedure type results in a retrieval of the getter and a
2729 jump back to the correct eval dispatcher.
2731 Representation 4 was selected because of efficiency and
2734 Rep 1 has the advantage that there is zero penalty for closure
2735 getters, but primitive getters will get considerable overhead
2736 because the procedure-with-getter will be a closure which calls
2739 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
2740 <procedure-with-setter>, but together with rep 2 it suffers from a
2741 three level dispatch for non-GOOPS getters:
2743 cclo/struct --> dispatch proc --> getter
2745 This is because the dispatch procedure must take an extra initial
2746 argument (cclo for rep 2, struct for rep 3).
2748 Rep 4 has the single disadvantage that it uses up one tc7 type
2749 code, but the plan for uniform vectors will very likely free tc7
2750 codes, so this is probably no big problem. Also note that the
2751 GETTER and SETTER slots can live directly on the heap, using the
2752 new four-word cells.
2754 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,

2834 * random.c: Removed alloca includes.
2836 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
2838 * Makefile.in: This changed, for some reason I don't really
2839 understand, when I ran automake in the top level directory. This
2840 may be contamination by Cygnus internal releases. If you re-run
2841 automake and this change gets reverted, don't worry about it.

2871 scm_guardian_gc_init, scm_guardian_zombify, scm_guard,
2872 scm_get_one_zombie, scm_init_guardian): This is an implementation
2873 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
2874 David Eby (1993) "Guardians in a Generation-Based Garbage
2875 Collector" ACM SIGPLAN Conference on Programming Language Design
2876 and Implementation, June 1993 ftp://ftp.cs.indiana.edu

2892 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2894 Move the procedure slots of entities to invisible slots (so that
2895 we can have operator class objects which themselves are entities).
2896 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
2897 SCM_STRUCTF_ENTITY): New constants.
2899 * struct.c (scm_make_struct): Allocate "invisible" room for
2900 procedures if SCM_STRUCTF_ENTITY is set in vtable.

2912 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
2914 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
2915 of syntactic forms, similar to SCM_PROC.
2916 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
2917 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
2918 for the name symbols when needed.
2920 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
2922 * Makefile.in: Regenerated.
2924 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
2926 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
2927 take the address of _into; it might be a register. Just have
2928 scm_debug_newcell return the new cell.
2929 * gc.c (scm_debug_newcell): Just return the new cell, instead of
2930 taking the address of a place to store it as an argument.
2931 * gc.h (scm_debug_newcell): Change declaration.
2932 (Thanks to Greg Harvey.)
2934 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

2955 * objects.h: Removed slots direct_supers and direct_slots from the
2956 definitions of the rudimentary classes described by objects.h.
2958 * objects.c, objects.h (scm_entity_p): New procedure. Together
2959 with the predicates scm_procedure_p and scm_struct_p, this
2960 predicate makes it possible to differ between structs, entities
2963 * modules.c, modules.h (scm_resolve_module): New function.
2965 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2967 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,

2978 * procprop.h (scm_i_procedure_arity): Added declaration.
2980 * procprop.c (scm_i_procedure_arity): Made global; New code to
2981 handle operators and entities.
2982 (scm_procedure_property): No need to call scm_procedure_p since
2983 scm_i_procedure_arity now does all necessary type checking.
2984 Added #include "objects.h".
2986 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
2987 s_add_hook_x --> s_remove_hook_x.
2988 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.

2992 (scm_make_hook): Optional argument defines number of arguments to
2994 (scm_make_named_hook): Take number of args as second arg.
2995 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
2996 boot-9.scm for a while); First arg is the hook. The rest are
2997 arguments passed on to the hook procedures.
2999 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
3001 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
3002 scm_logbit_p): Do the computation in ulongs. This is not as nice
3003 as doing it in bignums, but at least it's good enough for
3004 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
3006 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
3007 subexpressions. (Thanks to Charbel Jacquin.)
3009 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
3011 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
3012 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
3013 (scm_make_named_hook): New function.
3015 * feature.c: Added #include "eval.h".
3017 * modules.c (scm_make_module): Beautify the module.
3019 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3021 * modules.c, modules.h: New files: C interface to modules. (This
3022 is necessary in order to interface the object system to Guile
3023 properly. The guts of these modules will be replaced by the new
3024 module system in the future.)
3026 * init.c: Added #include "modules.h"
3027 (scm_boot_guile_1): Call scm_init_modules.
3028 (invoke_main_func): Call scm_post_boot_init_modules.
3030 * Makefile.am: Added modules.c, modules.x, modules.h.
3032 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
3034 * procs.c: #include "objects.h"
3035 (scm_procedure_p): Return #t also on structs which are operators.
3037 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
3038 <operator-metaclass> and <entity-class> to <standard-class>,
3039 <operator-class> and <entity> in order to conform with STKlos
3042 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
3043 which isn't an operator.
3044 (SCM_APPLY): Ditto, but jump to badproc.
3046 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
3048 * eval.c (SCM_CEVAL): Allow structs implanted in code.
3049 Previously, structs implanted in code were interpreted as forms
3050 the operator of which was a gloc. We solve this by checking for
3051 the zero in the emulated vcell in the struct vtable. Since
3052 implanted structs always will look like forms with a gloc
3053 operator, execution will only be slowed down by maximally one
3054 extra test-and-branch per application.
3056 * evalext.c (scm_definedp): Removed check for isyms; Added a
3057 second optional argument: It is now possible to supply an
3058 evaluation environment in which to look for the symbol.
3060 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3062 * readline.c (scm_init_readline): Set
3063 rl_basic_word_break_characters. (Thanks to Ian Grant.)
3065 * coop.c (coop_condition_variable_wait): Removed
3066 (coop_condition_variable_wait_mutex): Folded logic of
3067 coop_mutex_unlock into coop_condition_variable_wait_mutex to
3068 prevent condvar signal lossage. Previously, another thread could
3069 start to run after unlocking the mutex but before putting the
3070 current thread on the wait queue. If that thread then would
3071 signal the first, the signal would be lost. (Thanks to Christian
3074 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3076 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
3079 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3081 * objects.c (scm_i_make_class_object): Renamed from
3082 make_class_object; exported; error checking moved to
3083 scm_make_class_object and scm_make_subclass_object.
3084 (scm_make_class_object, scm_make_subclass_object): Use
3085 scm_i_make_class_object.
3086 (scm_make_subclass_object): Let the subclass have same metaclass
3089 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3091 * debug.c (scm_debug_options): Bugfix: Set the value of
3092 scm_stack_checking_enabled_p after setting debug options;
3093 #include "stackchk.h". (Thanks to Richard Polton.)
3095 1998-11-13 Radey Shouman <rshouman@metro2000.com>
3097 * unif.c (scm_array_contents): removed unnecessary test for 0
3100 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3102 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
3103 Replaced by macro `collect' in boot-9.scm.
3105 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3107 * eval.c (scm_copy_tree): Copy source properties if existent.
3109 * debug.c (scm_start_stack): Copy source when evaluating. (If we
3110 don't, we may end up passing memoized source to a transformer.)
3112 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3114 * stack.c (get_applybody): Help function which lookups the first
3115 body form of the apply closure.
3116 (read_frames): Prevent the source of the first form of the apply
3117 closure from being recorded. This would only be confusing.
3119 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
3120 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
3122 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
3124 * stacks.c (read_frame): Bugfix: Removed lingering `else'
3126 (read_frames): Use SCM_MACROEXPP.
3128 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3130 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
3131 don't contain interesting information since all arguments are
3132 present in the frame which applies the compiled closure anyway.);
3133 Skip the transformer application frames.
3135 * print.c (scm_iprin1): Print gsubrs as primitives.
3137 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3139 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
3141 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
3142 that we can identify these in a backtrace. (This change doesn't
3143 introduce any significant speed penalty.)
3145 * eval.c: Added note about `serial-map' using scm_map.
3147 * read.c, read.h (scm_read_options, scm_read_opts): Removed
3148 readline options. They should reside in their own options array.
3150 * readline.c, readline.h (scm_readline_options,
3151 scm_readline_opts): Moved readline options here.
3153 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3155 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
3156 SCM_ROCHARS instead of SCM_CHARS.
3158 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
3159 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
3161 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3163 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
3164 This is quite important since the latter clears the
3165 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
3166 every single character read...
3168 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3170 * print.c (scm_iprin1): Removed suspect looking (and indeed
3171 malevolent) semicolon after test for user supplied closure print
3172 procedure. (Thanks to Telford Tendys.)
3174 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
3175 (scm_memq, scm_memv, scm_member): Do argument checking *before*
3176 starting to search the list. Removed call to sloppy_mem_check.
3178 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
3179 procedures: Same as scm_delq_x et al, but delete maximally one
3182 * options.c (scm_options, scm_init_options): GC-protect option
3183 values of type SCM. (Thanks to Telford Tendys.)
3185 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3187 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
3188 make sure that there always is a "real" scm_lookupcar.
3190 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3192 * read.c, read.h (scm_read_opts): New read options
3193 "history-length" and "history-file".
3194 (scm_read_options): Stifle history to history length.
3196 * readline.c (scm_read_history, scm_write_history): New procedures.
3198 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3200 * eval.h (scm_macro_eval_x): Removed declaration.
3202 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
3203 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
3204 Renamed and made global.
3206 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
3207 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
3209 * evalext.c, evalext.h: New files. Contain non-R5RS things
3210 having to do with evaluation.
3212 * evalext.c (scm_serial_map): New procedure: Version of `map'
3213 which guarantees that the procedure is applied to the lists in
3215 (scm_m_sequence_to_list): New syntax: Version of `begin' which
3216 returns a list of the results of the body forms instead of the
3217 result of the last body form.
3218 (scm_definedp, scm_m_undefine): Moved from eval.c
3220 * evalext.h (scm_m_sequence_to_list): Added declaration.
3222 * macros.c, macros.h: New files.
3223 (scm_procedure_to_syntax, scm_procedure_to_macro,
3224 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
3225 scm_macro_name, scm_macro_transformer): Moved from eval.c
3226 (scm_make_synt): Moved from eval.c
3228 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
3230 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
3233 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
3235 * debug.c, print.c: Added #include "macros.h".
3237 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3239 This change adds the ability to use `unread-char' multiple times
3240 without interspersed reads and adds the new procedure
3241 `unread-string'. The change is optimized for the common case of
3242 unreading a single character. This is also the reason behind the
3243 choice to store characters in the port itself: in most cases no
3244 extra malloc is required.
3246 The amount of code in some macros in ports.h has been increased to
3247 the extent that they would fit better as C functions, but, since
3248 this code belongs to the port representation, such functions
3249 should be placed in ports.c which would cause calls back and forth
3250 between ports.c and genio.c. That is not good for performance.
3251 Also, keeping them as macros allows the compiler to do some
3252 optimizations which are needed to make the current interface
3253 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
3255 One benchmark (Guile startup time) indicates an increase of
3256 loading speed of 1%. Another (reading (using `read') boot-9.scm
3257 10 times) shows no change in performance.
3259 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
3260 made to find a beautiful solution.)
3262 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
3263 (SCM_TRY_CLRDY): New macro: Only clear the first unread
3264 character. (SCM_CLRDY clears all.)
3265 (SCM_N_READY_CHARS): New macro: Returns number of unread
3266 characters in a port. Returns wrong answer if SCM_CRDYP is false.
3267 (struct scm_port_table): New fields: `entry' contains port table
3268 index, `cp' points to last unread char, `cbuf' is the buffer for
3269 unread chars, `cbufend' points after end of the character buffer.
3271 * ports.h, ports.c (scm_unread_string): New procedure.
3272 (scm_grow_port_cbuf): New function.
3274 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
3276 (scm_generic_fgets), fports.c (local_fgets): Use a loop
3277 to read unread characters. Use SCM_TRY_CLRDY instead of
3280 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
3282 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
3284 * genio.c, genio.h (scm_ungets): New function.
3286 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
3289 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3291 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
3292 declarations. (Thanks to Russ McManus.)
3294 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3296 * numbers.c (num2long): As a software archeologist, I'm proud of
3297 this finding! :) Preliminary dating suggests an almost 4 year old
3298 remnant from the SCM ancestor. The sample has been removed from
3299 the finding site and is now safely stored in the repository.
3301 * numbers.h: Removed prototype for num2long.
3303 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
3305 * gh_data.c (gh_scm2doubles): Make it possible to pass result
3306 array as second arg.
3307 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
3308 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
3309 * gh.h: Updated and added prototypes.
3311 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
3313 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
3315 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
3317 * guile-snarf.in: Never generate an empty file. (Thanks to
3320 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
3321 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
3322 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
3323 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
3324 gh_new_procedure5_0): Specify argument types, to appease C++
3325 compilers. (Thanks to Brad Bowman.)
3327 Bug reports from Russ McManus:
3328 * guile-snarf.in: If the CPP environment variable is set, use that
3329 as the C preprocessor, instead of the preprocessor autoconf
3331 * snarf.h (SCM_PROC): Cast the function pointer passed to
3332 scm_make_gsubr, to satisfy C++.
3334 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
3335 Use the handler passed, instead of ignoring it and using
3336 gh_standard_handler. (Thanks to Etienne Bernard.)
3338 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
3340 * ports.h: Put text after #endif in comment. (Thanks to Nicolas

3364 use-emacs-interface in the root module, so the repl code can see
3365 it. See today's change to top-repl in ice-9/boot-9.scm.
3367 * filesys.c (set_element, get_element): Make sure that `element'
3368 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
3369 Boekemeier and Jorgen "forcer" Schaefer.)
3371 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
3373 * chars.c (scm_charnames): In ASCII character name table, make
3374 newlines print as #\newline by default, not #\nl.
3376 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
3377 alphabetical order. Oh thrills. But it helps me know how far
3378 along in the compilation I am.
3379 * Makefile.in: Regenerated.
3381 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3383 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
3384 #bytes(...) to #y(...), and syntax for short vectors from
3385 #short(...) to #h(...). This may seem nutty, but, like the other
3386 uniform vectors, byte vectors and short vectors want to have the
3387 same print and read syntax (and, more basic, want to have read
3388 syntax!). Changing the read syntax to use multiple characters
3389 after the hash sign breaks with the conventions used in R5RS and
3390 the conventions used for the other uniform vectors. It also
3391 introduces complexity in the current reader, both on the C and
3392 Scheme levels. (The Right solution is probably to change the
3393 syntax and prototypes for uniform vectors entirely.)
3395 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
3397 Don't use local_fgets on sockets; ftell doesn't work on sockets.
3398 (Thanks to Jorgen "forcer" Schaefer.)
3399 * ports.h (SCM_NOFTELL): New flag.
3400 * fports.c (local_fgets): If it's set, use the generic fgets.
3401 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
3403 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3405 * script.c (scm_compile_shell_switches): Add handling of -q switch
3406 (inhibit loading of user init file).
3407 (scm_shell_usage): Add usage text for -q switch.
3408 (scm_compile_shell_switches): Always load user init file first if
3409 it is loaded at all.
3411 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
3413 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
3414 and is now broken under NetBSD. I can't fathom what it's trying
3415 to do, so I've replaced it with something that I do understand,
3416 which seems to work, and which isn't broken on NetBSD. "Progress?
3417 You Decide." (Thanks to Perry Metzger.)
3419 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
3420 signed/unsigned comparison.
3422 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
3424 Warning fixes from Greg Harvey:
3425 * unif.c (scm_array_set_x): initializer for pos
3426 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
3427 * struct.c (scm_struct_ref, scm_struct_set_x): Added
3428 initializers for field_type, since EGCS so desparately wants to
3430 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
3431 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
3432 when GUILE_DEBUG is defined.
3433 * dynwind.h (scm_wind_chain): Same.
3434 * ports.h (scm_pt_size, scm_pt_member): Same.
3435 * print.h (scm_current_pstate): Same.
3436 * procs.h (scm_make_cclo): Same.
3438 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
3440 Handle short and long long uniform arrays properly. (Thanks to
3442 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
3443 raeql_1): Add cases for scm_tc7_svect (short vectors) and
3444 scm_tc7_llvect (long long vectors).
3446 Change the way libguile and boot-9.scm are timestamped, to try to
3447 get rid of these spurious mismatch warnings. Now both
3448 libguile/versiondat.h and ice-9/version.scm are generated directly
3449 by the configuration process, rather than having version.scm
3450 generated directly, and libguile/versiondat.h generated by the
3451 Makefile, which is generated by configure. It seems that
3452 sometimes the Makefile would change, but versiondat.h depends on
3453 Makefile.in, not Makefile, so it wouldn't get rebuilt.
3454 * Makefile.am (versiondat.h): Target removed; this is generated
3455 directly by the configure script now.
3456 (BUILT_SOURCES): Remove versiondat.h.
3457 * versiondat.h.in: New file, transformed by the configure script
3459 * Makefile.in: Regenerated.
3461 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
3462 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
3463 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
3464 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
3465 if we want to use them in a header file some day, we can. (Thanks
3466 to Michael Livshin.)
3468 * stime.c (scm_get_internal_real_time): Do the arithmetic using
3469 SCM numbers, so we won't have rollover problems; the range of a
3470 signed long in milliseconds is about 25 days. (Thanks to Karl
3473 Don't redefine sleep and usleep; fix this problem now.
3474 * coop.c (sleep, usleep): Remove declarations; we don't use or
3475 redefine these any more.
3476 (scm_thread_usleep, scm_thread_sleep): New functions which do the
3477 job of usleep and sleep in a thread-friendly way. We can use
3478 these in the rest of Guile. Define versions for systems both with
3479 and without iselect.
3480 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
3481 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
3482 we're just using it, not redefining it, we can use a K&R style
3484 (sleep): Declare this, too, if the system hasn't.
3485 (scm_sleep, scm_usleep): Use scm_thread_sleep and
3486 scm_uthread_sleep if they're available; otherwise, just call the
3488 * scmconfig.h.in: Regenerated.
3490 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
3492 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
3494 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
3496 * threads.c: Doc fix.
3498 The argument type of usleep varies from system to system,
3499 as does the return type. We really shouldn't be redefining usleep
3500 at all, but I don't have time to clean that up before the 1.3.
3501 release. It's on the schedule for afterwards. (Thanks to Julian
3503 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
3505 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
3506 * scmconfig.h: Regenerated.
3508 * simpos.c (scm_software_type): Procedure deleted. This isn't the
3509 right way to handle system variation. Autoconf's approach is the
3511 * simpos.h (scm_software_type): Declaration deleted.
3513 * script.c (scm_find_executable): Don't test if unix is #defined
3514 here; first, NetBSD doesn't #define it, and second, it's the wrong
3515 way to go about these things. (Thanks to Perry Metzger.)
3516 (dld_find_executable): Delete this MSDOS support code. This isn't
3517 the way we want to support this; it needs to be rethunk at a
3520 * genio.c (scm_do_read_line): Don't just politely check that the
3521 line was either non-empty or EOF. Abort if it's empty and not
3524 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
3526 * scmconfig.h.in: Regenerated.
3528 * libguile.h: Don't omit the dynamic linking functions. (Thanks
3531 * genio.c (scm_do_read_line): Count lines correctly when the file
3532 doesn't end in a newline.
3534 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
3536 * genio.c (scm_do_read_line): Maintain the line count correctly.
3537 (Thanks to Harvey J. Stein and Greg Harvey.)
3539 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
3542 * numbers.c (big2str): Protect t from garbage collection until
3543 we're done. (Thanks to Gary Houston.)
3545 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
3547 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
3549 * Makefile.in: Regenerated.
3551 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
3552 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
3555 Do magic to mix reads and writes on stdio FILE-based ports.
3556 (Thanks to Christian Lynbech.)
3557 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
3559 (pre_read, pre_write): New functions.
3560 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
3561 local_fputs): Call them.
3562 (local_fflush): Mark the port as ready for reading and writing.
3563 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
3564 flags on new port objects. This might not be accurate --- who
3565 knows what state the FILE * is in when we get it --- but it won't
3566 do extraneous calls to fflush or fseek, so it's no worse than the
3567 behavior before this change.
3568 * ports.h: Add comment.
3570 Centralize the creation of port objects based on stdio FILE * in
3571 fports.c; don't just throw them together anywhere.
3572 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
3573 what the rest of Guile wants. Don't set the revealed count;
3574 that's only appropriate for stdin, stdout, stderr.
3575 (scm_standard_stream_to_port): This function does set the revealed
3577 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
3578 not scm_stdio_to_port.
3579 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
3580 * fports.c (scm_open_file): Same.
3581 * posix.c (scm_pipe): Same.
3582 * socket.c (scm_sock_fd_to_port): Same.
3583 * ioext.c (scm_fdopen): Same.
3584 (scm_freopen): Moved from here to...
3585 * fports.c (scm_freopen): ... here. This is really something that
3586 munges the internals of an fport, so it should go here.
3587 * fports.h (scm_stdio_to_port): Adjust prototype.
3588 (scm_standard_stream_to_port, scm_freopen): New protoypes.
3589 * ioext.h (scm_freopen): Prototype removed.
3591 * filesys.c (set_element, get_element): This can work on both pipe
3592 and file ports, so use SCM_FPORTP to typecheck, instead of testing
3595 * scmconfig.h.in: Regenerated.
3597 Change the definition of the functions in scm_ptobfuns so that
3598 they get passed the port object, not the port's stream.
3599 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
3600 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
3601 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
3602 Pass the port itself to the scm_ptobs function.
3603 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
3604 scm_generic_fgets): Same.
3605 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
3606 getc_void_port, fgets_void_port, close_void_port): Just change the
3607 argument names; these functions don't really do anything.
3608 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
3609 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
3610 port as an argument, and use SCM_STREAM to get the stdio FILE *.
3611 Also, use prototyped definitions, and get rid of the extra
3613 (scm_fptob, scm_pipob): We don't need casts here any more.
3614 * strports.c (prinstpt): Use prototype declarations.
3615 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
3616 and use SCM_STREAM to get the string info. Also, use prototyped
3617 definitions, and get rid of the extra declarations.
3618 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
3621 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
3622 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
3624 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
3625 scm_fgets, for consistency.
3626 (scm_fptop, scm_pipob): References updated.
3628 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
3630 Include the source location in error messages for scripts.
3631 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
3632 stack is still there when we catch the error.
3633 * throw.c (handler_message): If we are handling an error with a
3634 message, then put together the proper arguments and call
3635 scm_display_error, instead of scm_display_error_message. That
3636 displays source location, if it can find it.
3638 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
3640 * gc.c (scm_unprotect_object): Change this so that calls to
3641 scm_protect_object and scm_unprotect_object nest properly.
3642 (scm_protect_object): Doc fixes.
3644 * strings.c (scm_string_set_x): Require the argument to be a
3645 writable string, not a substring or a symbol.
3646 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
3647 (Thanks to John Redford and Charbel Jacquin.)
3649 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
3651 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
3653 * eval.c (safe_setjmp): Remove this misunderstanding.
3654 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
3657 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
3659 * libguile.h: Mark these as C declarations, for compilation by C++
3662 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
3663 __cplusplus clause. I seriously doubt this ever worked the way
3664 the author seems to have intended.
3666 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
3668 Utterly needless cleanups to hopelessly messy code.
3669 * ports.c: Doc fixes.
3670 (scm_fflush): Moved to ...
3671 * genio.c (scm_fflush): ... here, amongst all the other port
3672 method invocation functions.
3673 * genio.h, ports.h: The prototype moves too.
3675 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
3677 * backtrace.c (display_error_body): The current frame does not
3678 always have a parent frame; consider a function called directly
3679 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
3682 * alloca.c (alloca): Undo yesterday's changes, and simply call
3683 malloc directly for storage, and abort if we don't get what we
3684 want. The situation is much simpler --- just call malloc. Emacs
3685 has bizarre/evil requirements (signal handlers might malloc unless
3686 you set this global flag, so you have to set the flag around all
3687 calls to malloc) which we are certainly not going to conform to,
3688 so we can do the simple and obvious thing.
3690 * coop.c (coop_condition_variable_wait): Make this function
3691 static. It's only useful internally --- you should never just
3692 wait on a condition variable.
3693 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
3695 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3697 * unif.c (scm_array_set_x): Accept any kind of number as an
3698 element for a uniform vector of doubles. This is more consistent
3699 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
3701 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
3702 works; I can't conveniently test it myself. (Thanks to Dvid
3703 Tillman for the bug report.)
3705 * init.c: Doc fixes.
3707 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
3708 from here, not from scm_compile_shell_switches (which is a pretty
3709 dumb place to do it).
3710 (scm_load_startup_files): New function.
3711 (scm_ice_9_already_loaded): Variable moved to here from script.c.
3712 * script.c (scm_compile_shell_switches): Don't load the startup
3714 (scm_ice_9_already_loaded): Variable moved.
3715 * init.c (scm_load_startup_files): Prototype for new function.
3716 * gh_init.c (gh_enter): Doc fix.
3718 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3720 Some anti-warning changes from Greg Harvey.
3721 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
3722 warnings when it doesn't understand our NORETURN declarations in
3724 * posix.c (scm_mknod): Similar.
3726 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3728 * posix.c (scm_getpwuid): If we can't find an entry, return our
3729 own message, instead of using scm_syserror --- the getpwMUMBLE
3730 functions don't set `errno' to anything interesting.
3732 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3734 Get rid of warnings from the cooperative threading system.
3735 * threads.h (scm_single_thread_p, scm_yield,
3736 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
3737 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
3738 scm_wait_condition_variable, scm_signal_condition_variable): Add
3739 prototypes for these Scheme-visible functions.
3740 * coop-defs.h (coop_next_runnable_thread,
3741 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
3742 Prototypes for these here, even though they're from iselect.c.
3743 (coop_condition_variable_wait, coop_join): Add prototypes.
3744 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
3745 scm_threads_free_condvar): Make these smob functions static.
3746 * coop-threads.h (coop_init): Give this a real prototype.
3747 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
3748 (coop_next_runnable_thread): No need to provide prototype; it's in
3751 * scmconfig.h.in: .detarenegeR
3753 * iselect.c, threads.c: Doc fixes.
3755 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3757 * Makefile.in: Regenerated with a patched automake, to get
3758 dependency generation right when using EGCS.
3760 * inet_aton.c (inet_aton): Add prototype, to remove compiler
3761 warning. (Thanks to Robert Pluim.)
3763 * inet_aton.c (inet_aton): Reassure the compiler that the
3764 arguments to the <ctype.h> macros are all unsigned characters, not
3767 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3769 Getting rid of more warnings...
3770 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
3771 today's change to ../configure.in.
3772 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
3773 * scmconfig.h.in: Regenertaded.de.,.__
3774 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
3775 (scm_localtime, scm_mktime): Use a const char * to manipulate the
3778 * readline.c: Doc fix.
3779 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
3780 * readline.h (scm_filename_completion_function): Add prototype.
3781 (scm_init_readline): Make this into a prototype.
3783 * readline.c (scm_filename_completion_function): Use SCM_PROC to
3784 declare this, instead of calling scm_make_subr manually.
3786 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
3788 * readline.h (scm_init_readline): Add prototype for this.
3789 (scm_init_readline): Make this a real prototype.
3791 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
3793 Warning fixes from Maciej Stachowiak:
3794 * backtrace.h (scm_display_application, scm_backtrace): Add
3796 * debug.c (scm_m_start_stack): Make this function static.
3797 * fluids.h (scm_fluid_p): Add prototype.
3798 * procprop.c (scm_i_procedure_arity): Make this function static.
3799 * regex-posix.c (scm_regexp_error_msg): Make this function static.
3800 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
3801 * root.h (scm_dynamic_root): Add external prototype.
3802 * scmsigs.h (scm_usleep): Add external prototype.
3803 * script.h (scm_init_script): Use prototype, not K&R decl.
3804 * stacks.h (scm_stack_id): Add external prototype.
3805 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
3807 1998-09-30 Mark Galassi <rosalia@cygnus.com>
3809 * gh.h: took out the definitions of vset and vref, since they are
3810 replaced by the proper vector routines that correspond to the R4RS
3813 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
3815 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
3816 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
3817 third argument, a C expression that should result in a SCM value,
3818 which is used to initialize the variable. Reimplemented
3819 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
3822 * version.h (scm_libguile_config_stamp): Add prototype.
3823 (From Maciej Stachowiak.)
3825 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
3827 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
3828 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
3830 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
3832 * print.c (scm_iprin1): Rather than having one i, and using it in
3833 several places, declare a fresh i local to each block where it is
3834 used, and give it a signedness appropriate to its use in each case.
3835 (scm_iprlist): Same.
3837 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
3838 comparison warnings.
3840 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
3841 signed/unsigned clashes.
3843 * posix.h (scm_tmpnam): Added prototype.
3845 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
3846 scm_make_subclass_object): Add external prototypes.
3848 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
3849 comparison is okay here.
3851 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
3853 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
3854 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
3856 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
3859 * load.c (swap_port): Make this function static.
3861 * load.c (scm_search_path): Make max_path_len and max_ext_len
3862 unsigned, since they're compared against string sizes.
3864 * load.c (init_build_info): Make i unsigned.
3866 * ioext.h (scm_read_line): Add prototype.
3868 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
3869 scm_hash_fn_remove_x): Make hash bucket index local variable k
3870 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
3871 accurately as possible.
3873 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
3874 comparisons, and range checking to make sure those casts are
3877 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
3878 signed/unsigned comparisons.
3880 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
3881 avoid signed/unsigned comparisons.
3882 * smob.h (scm_numsmob): Change extern declaration to match.
3884 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
3885 avoid signed/unsigned comparisons.
3886 * ports.h (scm_numptob): Change extern declaration to match.
3887 (scm_current_load_port, scm_set_port_line_x,
3888 scm_set_port_column_x): New prototypes.
3890 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
3891 test code, and it causes warnings.
3893 * gh.h (gh_int2scmb, gh_uniform_vector_length,
3894 gh_uniform_vector_ref): Added prototypes.
3896 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
3897 debugging support unconditionally. That's backtrace.c, stack.c,
3898 debug.c, and srcprop.c.
3899 (EXTRA_libguile_la_SOURCES): Omit those from here.
3900 * Makefile.in: Regenerated.
3902 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3904 * options.c (scm_options): Bugfix: Allow empty list of options!
3906 * debug.c, debug.h (scm_single_step): Removed.
3907 (scm_with_traps): New procedure. This procedure could easily be
3908 written in Scheme but needs to be highly optimized.
3910 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
3912 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
3913 Check SCM_TRAPS_P before trapping.
3915 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
3917 Changes to avoid signed/unsigned comparison warnings.
3918 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
3919 (scm_gc_sweep): Make n and j local to the blocks they're used in,
3920 so they can have appropriate types for each application. Make i
3921 signed. Use initializers in some spots. I'll probably pay for
3923 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
3924 (scm_must_realloc): Make nm unsigned.
3925 (init_heap_seg): Make new_seg_index and n_new_objects signed.
3926 (scm_init_storage): Use prototype-style definition, and make the
3928 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
3929 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
3931 * filesys.c (scm_readlink): Make local vars rv and size ints, to
3932 avoid signed/unsigned comparison warnings, and because the return
3933 value of readlink may be -1. Don't bother casting the third
3934 argument to readlink.
3936 * filesys.c (scm_dirname, scm_basename): Move these to their own
3937 page, at the end of the file.
3938 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
3940 * eval.h (scm_eval_options_interface): Add external prototype for this.
3941 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
3943 * eval.c (scm_lookupcar1): Make this static.
3945 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
3946 Make these prototype declarations, not K&R-style.
3948 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
3949 unsigned comparison warning.
3951 * appinit.c: File removed. It had a single function in it, empty,
3952 whose reason for existence is explained in no documentation or
3953 comment. I think it's there as a default for some Tcl-style
3954 initialization, but Tcl abandoned that approach a while ago.
3955 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
3956 (BUILT_SOURCES): Remove appinit.x.
3957 * Makefile.in: Regenerated.
3959 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3961 * Makefile.in: Regenerated using the last public version of
3962 automake, not the hacked Cygnus version.
3964 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
3966 Remove Totoro kludge.
3967 * Makefile.in, scmconfig.h.in: Regenerated.
3968 * init.c, readline.c: Don't check if TOTORO is #defined.
3970 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
3972 * Makefile.am: Adjust for new thread configuration system.
3973 (INCLUDES): Include the value of THREAD_CPPFLAGS.
3974 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3976 (THREAD_LIBS): Definition deleted; automake will generate such
3977 things automatically.
3978 * Makefile.in: Regenerated.
3980 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3982 Simplify smob and port marking; set the mark bit in the generic
3983 marking code, and make marker routines only responsible for
3984 turning up outgoing pointers.
3985 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3986 before calling the marking function. Don't call the marking
3987 function if it's zero.
3988 * markers.c (scm_mark0): Just return #f. This function isn't
3989 necessary at all now, but it's harmless to call it. We'll leave
3990 it in so other folks' code doesn't croak at link time.
3991 (scm_markcdr): Don't call SCM_SETGC8MARK.
3992 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3993 * dynl.c (mark_dynl_obj): Same.
3994 * root.c (mark_root): Same.
3995 * srcprop.c (marksrcprops): Same.
3996 * unif.c (markra): Same.
3997 * variable.c (scm_markvar): Same.
3998 * ports.c (scm_markstream): Same.
3999 (void_port_ptob): Specify zero for our marking function.
4000 * debug.c (debugobjsmob): Same.
4001 * dynwind.c (guardsmob): Same.
4002 * filesys.c (dir_smob): Same.
4003 * fluids.c (fluid_smob): Same.
4004 * fports.c (scm_fptob, scm_pipob): Same.
4005 * mallocs.c (mallocsmob): Same.
4006 * regex-posix.c (regex_t_smob): Same.
4007 * smob.c (freecell, flob, bigob): Same.
4008 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
4009 * throw.c (jbsmob, lazy_catch_funs): Same.
4011 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
4013 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
4014 scm_copy_tree on code in order not to let memoized code to leak
4015 out. Thus, scm_copy_tree needs to copy vectors as well since
4016 quasiquote can introduce evaluated code also inside vector
4019 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
4021 * eval.c (scm_copy_tree): Removed ability to copy vectors.
4023 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
4024 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
4027 * unif.c: Say that ivect and uvect are of type signed and unsigned
4028 long instead of int in commentary so that it correctly describes
4031 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
4033 * stime.c: Removed declaration of strptime. (It should be
4034 declared by the system headers. If it turns out that some systems
4035 don't, we'll handle that then.) (Thanks to Greg Troxel.)
4037 * stime.h: Renamed TIMEH --> STIMEH
4039 * backtrace.c (scm_display_error, scm_display_backtrace): In order
4040 to increase portability, don't use structure assignment.
4041 (Thanks to Nicolas Neuss.)
4043 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
4045 (finalize_fd_sets): Added empty statement after last case label.
4046 (Thanks to Nicolas Neuss.)
4048 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
4051 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
4053 * init.c, readline.c: OK, I won't have these readline.x bug
4054 reports anymore. We've had them since April. The current reason
4055 is a completely unintelligible failure of totoro.red-bean.com to
4056 do the test for rl_getc_function in libreadline correctly. This
4057 kludge overrides the test if we're on totoro so that the snapshot
4058 generation process can work.
4060 * readline.c: Define a strdup replacement if not existent on system.
4062 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
4064 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
4065 This change makes scm_make_vector R5RS compatible. We cannot keep
4066 the third argument since people want to be able to deduce the form
4067 of the C function call only by looking at R5RS. (At the same time
4068 we have removed some unnecessary complexity!)
4070 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
4071 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
4072 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
4073 argument in call to scm_make_vector.
4075 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4077 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
4078 This macro is useful in applications.
4080 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
4082 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
4083 (scm_parse_path, scm_search_path): New Scheme level procedures.
4085 * load.h (scm_internal_parse_path, scm_parse_path,
4086 scm_search_path): Declared.
4088 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4090 * filesys.c (dirname, basename): New procedures.
4092 * init.c (scm_boot_guile_1): Removed condition around
4095 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
4096 new data type (guards) for representation of C level guards and
4097 data on the wind chain.
4098 (scm_internal_dynamic_wind): New function.
4100 * dynwind.h: Declare scm_internal_dynamic_wind.
4102 * root.h (scm_root_state): Added scm_cur_loadp.
4104 * root.c (mark_root): Added comment about cur_loadp.
4106 * load.c: #include "dynwind.h";
4107 (scm_primitive_load): Use scm_inner_dynamic_wind to update
4110 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
4112 * ports.c (current-load-port): New procedure.
4114 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4116 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
4117 not a tty, return #f.
4119 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
4120 to Julian Satchell and Roland Kaufmann.)
4122 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
4123 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
4125 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
4127 * debug.h, debug.c (scm_start_stack): New function. Implements
4128 the guts of old scm_m_start_stack.
4130 * debug.c (scm_m_start_stack): Use scm_start_stack.
4132 * init.c (scm_start_stack, scm_restart_stack): Renamed to
4133 start_stack and restart_stack. (These have static scope.)
4135 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4137 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
4138 readline functions to come in release 2.3. (Thanks to Chet
4140 (handle_errors): Use the above functions.
4142 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4144 * readline.c: Improvements for readline support: Handle errors
4145 better; Implement before-read-hook.
4147 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4149 * init.c (scm_boot_guile_1), readline.c: Test for
4150 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
4151 assure that we have version >= 2.1.)
4153 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
4155 * readline.c (scm_readline): Defer interrupts while we're calling
4158 * readline.c (scm_add_history): Bugfix: Do strdup before giving
4159 away the string to add_history.
4160 (completion_function): Do completion for readline. (Thanks to
4162 (scm_filename_completion_function): New procedure: Filename
4164 (current_input_getc): New function. Use this one instead of
4165 standard getc from readline.
4167 * throw.c, throw.h (scm_handle_by_throw): New function: This
4168 handler throws errors to next handler on the dynwind chain.
4170 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
4172 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
4175 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4177 * procprop.c (scm_i_procedure_arity): New function. Returns arity
4179 (scm_procedure_properties): Modified to return arity together with
4181 (scm_procedure_property): Added the read-only property `arity'.
4182 (scm_set_procedure_property_x): It is an error to set the `arity'
4185 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
4186 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
4188 * procprop.h (scm_sym_arity): New symbol.
4190 * objects.c (scm_set_object_procedure_x): New procedure: Use this
4191 to set the dispatch procedure of an operator or entity object.
4193 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
4194 Made procedure slots read-only.
4196 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
4197 scm_tcs_cons_gloc case in zero args switch; Fixed args
4198 construction for operators in scm_tcs_cons_gloc case in two args
4201 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4203 * fluids.c: Removed use of assert.h (in order to avoid
4206 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
4208 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
4210 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
4211 change makes the evaluator safer at the cost of evaluation speed.
4212 It handles the case when the user has added a non-immediate
4213 improper end of the application form, e.g., `(+ 0 . x)'.
4214 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
4215 minimize the extra cost as much as possible. The new code is
4216 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
4217 problem with structs planted directly in the code (e.g. by a
4218 macro). This no longer causes segmentation fault. (Thanks to
4221 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
4222 arg `proc' in order to be able to throw errors; New argument
4225 * Removed extra #include "debug.h"
4227 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
4229 * scmsigs.c: Declare usleep as returning void on some systems.
4230 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
4233 * coop.c (usleep): Return void on some systems.
4235 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4237 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
4239 * coop.c: Changed return type of usleep to int.
4241 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
4242 isn't found in the OS.
4244 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
4245 isn't enabled. (Thought that I had made this change ages ago...)
4247 * iselect.c: Declare bzero if not defined by OS.
4249 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4251 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
4252 condition. (Thanks to John Tobey.)
4254 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
4255 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
4258 * __scm.h: Start the long-term project of moving to POSIX threads.
4259 Phase 1: Classification of all critical sections.
4260 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
4261 for A sections. (See comments in __scm.h for details.)
4263 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
4264 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
4266 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4268 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
4269 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
4270 (libpath.h, versiondat.h): Replaced dependency on Makefile with
4271 dependencies on $(srcdir)/Makefile.in
4272 $(top_builddir)/config.status in order to avoid circularity.
4274 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
4275 from argc if argc was 0 initially.
4277 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
4278 in generation of libpath.h.
4280 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
4282 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
4283 libguile from 2 to 3.
4285 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
4287 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
4289 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
4291 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
4292 scm_set_port_column_x, scm_port_filename,
4293 scm_set_port_filename_x): Removed optional arguments. Added
4294 proper argument checking.
4296 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
4297 stack size in machine words.
4299 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
4300 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
4301 to Ole Myren Röhne.)
4303 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
4305 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
4306 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
4308 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
4311 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
4312 procedure apply: Copy argument lists before pushing them unto the
4313 environment so that the environment won't get mutated due to
4314 manipulation of procedure arguments. This should perhaps be
4315 regarded as a temporary solution until someone finds a more
4316 efficient one. (Thanks to Maciej Stachowiak.)
4318 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
4320 * script.c (scm_compile_shell_switches): Use "guile" as default
4321 zero arg if argc is NULL.
4323 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
4325 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
4326 is zero. (Thanks to Dirk Herrmann.)
4328 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
4330 * ports.c (scm_add_to_port_table): First line is now line 0
4331 (was 1). (Interface changed according to suggestion by Per
4334 * backtrace.c (display_header): Add 1 to line and column numbers
4335 when presenting them to the user.
4337 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
4338 from debug.c --> eval.c
4340 * eval.h, eval.c (scm_eval_options_interface): New options
4342 (SCM_EVAL_STACK): New option: Size of newly created stacks,
4343 i.e. stacks for new threads.
4345 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
4347 * eval.c (unsafe_setjmp): Removed with #if 0.
4349 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
4352 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
4353 to avoid compiler warnings.
4355 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
4357 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
4359 * throw.c (handler_message): Print message on current error port
4360 instead of default error port. (Thanks to Maciej Stachowiak.)
4362 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
4364 * ports.c (scm_add_to_port_table): allocate in units of
4365 struct scm_port_table *, not struct scm_port_table.
4366 * posix.c (scm_close_pipe): remove the port from the port table
4368 Thanks to Rob Engle for both fixes.
4370 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4372 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
4373 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
4375 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4377 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
4379 * backtrace.c (display_error_body, display_backtrace_body),
4380 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
4381 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
4382 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
4383 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
4386 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
4387 don't receive the jmpbuf arg anylonger.
4388 (scm_catch): Don't accept a #f tag.
4389 (scm_throw): Check that key is a symbol.
4390 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
4392 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
4394 * async.c (async_pending): Removed declaration.
4396 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4398 * dynwind.c (scm_wind_chain): New debug function.
4400 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
4401 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
4402 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
4403 extra layer of functions around the body and handler of a thread.
4404 This extra layer makes sure that the handler is called in the
4405 dynamic context of the surround (= empty dynwind list), but under
4406 the *dynamic root* of the body. We can not use the dynamic root
4407 of the surround since that root belongs to another thread => stack
4408 is not handled correctly. It may seem ugly to use this extra
4409 layer, but the extra cost in terms of execution time is really
4410 negligible compared to the total amount of time required to create
4411 a thread, and it would reduce maintainability to duplicate the
4412 crucial and complicated steps performed by cwdr.
4414 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
4415 (SCM_ALLOW_INTS): Added thread switching code before interrupts
4416 get re-enabled. The important effect of this is that interrupts
4417 are blocked during thread switching so that thread data structures
4418 don't risk getting messed up by an unfortunate signal.
4419 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
4420 seems to do more aggressive optimization which actually move
4421 instructions around in these macros in a fatal way. Therefore:
4422 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
4423 just superstitious...)
4424 (SCM_TICK): Maybe do a context switch and take care of asyncs.
4425 This macro should be used instead of SCM_ASYNC_TICK since the
4426 latter doesn't do context switches any more.
4428 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
4429 instead of SCM_ASYNC_TICK.
4431 * coop.c, iselect.c: Since thread switches are now performed with
4432 interrupts masked, we can't use the old mechanism of delivering
4433 signals immediately when they arrive. Signals must instead be
4434 delivered when the asyncs run *after* the end of the critical
4435 section in scm_internal_select. But this also means after context
4436 switch so that the signal will be delivered to a different thread.
4437 To avoid this, I have changed the protocol of
4438 coop_wait_for_runnable_thread and friends so that they are allowed
4439 to return the original thread. So, if a signal arrives during
4440 scm_internal_select, we won't any longer be forced do a context
4441 switch, but can remain in the same thread and deliver the signal
4444 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
4445 scm_asyncs_pending and made it global.
4447 * iselect.c: Small fixes.
4449 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
4450 coop_condition_variable_init, coop_condition_variable_wait,
4451 coop_condition_variable_signal): Changed return type from `void'
4452 to `int'. This is to adhere closer to the pthreads interface.
4453 This, in turn, is part of an attempt to provide C versions of the
4454 mutex and condition variable primitives which can be part of a
4455 frontend to COOP or pthreads.
4457 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
4458 coop_condition_variable_destroy): New functions.
4460 * coop-threads.c (scm_wait_condition_variable): Use
4461 coop_condition_variable_wait_mutex.
4463 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
4464 Definitions moved to coop-defs.h.
4466 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
4467 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
4468 scm_cond_destroy): New C interface to mutecis and cond vars.
4470 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4472 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
4474 * iselect.c: Now several threads can wait on the same file
4475 descriptor. The behaviour is compatible with OS select: All
4476 threads waiting for the fd return with the same status.
4478 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4480 * coop-threads.c, threads.h (scm_spawn_thread): New function.
4481 Can spawn a thread from application C code.
4483 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4485 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
4486 gh_doubles2scm): New functions.
4488 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
4490 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
4491 commented-out version of gh_eval_str()
4493 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
4495 * socket.c (scm_bind): free soka after use.
4497 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
4499 * stime.c (tzvar): new variable.
4500 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
4501 avoid memory leaks when allocating.
4503 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
4505 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
4508 * gc.c, tags.h: Doc fixes.
4510 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4512 * eval.c (macro-eval!): Removed. This function was a design bug.
4513 It allowed memoized code to leak out to the scheme level. Most
4514 things that you could do with `macro-eval!' can be done with
4517 1997-12-20 Tim Pierce <twp@skepsis.com>
4519 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
4520 scm_fgets now depends on ftell(3) to know how many bytes were
4523 1997-12-15 Tim Pierce <twp@skepsis.com>
4525 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
4526 dealing with strings.
4528 1997-12-13 Tim Pierce <twp@skepsis.com>
4530 Make %read-line more suitable for implementing read-line efficiently.
4531 * ioext.c (scm_read_line): Strip the terminating newline from a
4532 string, and return a cons of the string and its terminator.
4534 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
4535 of the string that is read is stored in this memory location.
4536 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
4537 * genio.c, genio.h (scm_do_read_line): Update caller.
4538 * ports.h (scm_ptobfuns): Update typedef.
4539 * fports.c (scm_fptob, scm_pipob): Update struct.
4541 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4543 * filesys.c (set_element): Return file descriptor.
4544 (fill_select_type): Return the highest file descriptor.
4545 (scm_select): Tell select about the highest file descriptor. On
4546 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
4547 Therefore the extra overhead for calculating the maximum fd seems
4548 to be more than compensated. Is this correct? In any case,
4549 scm_internal_select will be much faster with this info.
4550 (scm_select, fill_select_type, set_element): Don't accept any kind
4551 of object in the file descriptor list or vector.
4553 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4555 * iselect.c (finalize_fd_sets): Bugfix.
4557 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4559 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS

4563 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
4565 * simpos.c (scm_system): always define: use sysmissing if not
4566 available. Check for HAVE_SYSTEM instead of _Windows (does
4567 Windows lack system or does it have an unusable one?).
4568 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
4569 Let the argument be optional: if not supplied, call system(NULL).
4571 * ports.c (scm_close_port): relax the type check from OPPORTP to
4572 PORTP; closing a closed port is allowed.
4574 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
4576 * fports.c (scm_fgets): Return if the last char in a chunk is
4577 newline. When fgets returns a string whose length is `size-1', it
4578 is ambiguous whether a whole line was retrieved, so we must check
4579 explicitly whether a line terminator is present.
4581 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4583 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
4584 before taking the CDR. (Thanks to Harald Meland.)
4586 * filesys.c (scm_stat): Slightly optimized.
4588 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
4590 * ports.c (scm_close_port): Make sure the port is open before
4593 * guile-snarf.in: Pass args through to gcc in a way that preserves
4594 whitespace boundaries. (Thanks to Greg Badros.)
4596 1997-12-02 Tim Pierce <twp@skepsis.com>
4598 * stacks.c (scm_frame_procedure): Reverse the logic in the return
4599 statement. (Thanks to Doug Evans for pointing this out.)
4601 1997-12-01 Tim Pierce <twp@skepsis.com>
4603 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
4605 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
4607 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
4608 errno macro expansion of this field name. (errno is a C
4609 preprocessor macro on some systems.)
4611 1997-11-29 Tim Pierce <twp@skepsis.com>
4613 * iselect.c: Doc fix.
4615 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>

4624 * root.c (mark_root): Don't mark the_last_stack_var.
4626 * root.h (scm_root_state): Removed the_last_stack_var.
4628 * throw.c: Added #include "fluids.h"
4629 (ss_handler): `the-last-stack' is now a fluid.
4631 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
4632 --> the_last_stack_fluid.
4634 * backtrace.c: Added #include "fluids.h"
4635 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
4636 (scm_backtrace): `the-last-stack' is now a fluid.
4638 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
4639 after scm_init_fluids.
4641 1997-11-28 Tim Pierce <twp@skepsis.com>
4643 * iselect.c: #ifdef USE_THREADS around thread-related includes.
4645 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
4646 DLSYM_ADDS_USCORE to decide whether to add an underscore.
4648 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4650 * iselect.c (coop_next_runnable_thread,
4651 coop_wait_for_runnable_thread): Disable interrupts so that no
4652 async is executed before a potential error_revive.
4653 (scm_internal_select): Disable interrupts during the parts of the
4654 code which manipulate the sleep queue and the file descriptors.
4656 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4658 * Makefile.am: Added iselect.c and iselect.h.
4660 * coop.c (coop_qinit): Initialize fields used by
4661 scm_internal_select.
4662 (coop_qget, coop_qget, coop_tmp_queue): Made global.
4663 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
4664 replacement in iselect.c.
4665 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
4666 coop_join): If GUILE_ISELECT enabled, use
4667 coop_wait_for_runnable_thread instead of
4668 coop_next_runnable_thread.
4669 (usleep, sleep): New replacements for system functions if
4670 GUILE_ISELECT is enabled.
4672 * coop-threads.h: Declare coop_wait_for_runnable_thread.
4674 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
4676 * filesys.c: Added #include "iselect.h". Moved FD-macros to
4677 iselect.h. Implement Scheme level `select' using
4678 scm_internal_select. (See NEWS.)
4680 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
4682 * init.c: Call scm_init_iselect.
4684 * iselect.h, iselect.c: New files. Implements
4685 scm_internal_select. (See NEWS.)
4687 1997-11-27 Tim Pierce <twp@skepsis.com>
4689 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
4690 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
4691 and scm_must_free, since ultimately the string returned will be copied
4692 by scm_makfrom0str anyway. Also, read any characters that may have
4693 been pushed onto the port with scm_ungetc.
4694 * ports.c (scm_generic_fgets): Same as for scm_fgets.
4695 * ioext.c (scm_read_line): Free string after Guilifying it.
4696 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.

4700 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
4702 * gh.h: Safely wrap prototypes for c++ usage.
4704 1997-11-25 Mark Galassi <rosalia@cygnus.com>
4706 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
4707 gh_repl (argc, argv).
4709 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
4711 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
4712 and to invoke scm_shell().
4713 (gh_launch_pad): took out the loading of boot-9.scm from here,
4714 since it is probably best to let the user control that. In fact,
4715 gh_repl() now invokes scm_shell() which does that.
4717 1997-11-23 Mark Galassi <rosalia@cygnus.com>
4719 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

4741 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
4742 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
4744 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
4746 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
4747 configure.in was changed).
4749 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
4751 * Makefile.am (modinclude_HEADERS): Include readline.h here.
4752 * Makefile.in: Regenerated.
4754 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
4756 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
4757 OPORT is an `open' port, not an output port.
4759 * filesys.c (scm_close, set_element, get_element, scm_chown,
4760 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
4761 SCM_COERCE_OUTPORT to cope with the printstate/port magic.

4764 scm_port_column, scm_set_port_column_x, scm_port_filename,
4765 scm_set_port_filename_x, scm_port_mode,
4766 scm_close_all_ports_except, scm_set_current_output_port,
4767 scm_set_current_error_port): Likewise
4768 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
4769 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):

4772 * backtrace.c (display_backtrace_body): Likewise
4773 * fports (scm_setvbuf): Likewise

4781 Minor problems with substring-related tag changes.
4782 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
4783 exactly what we want to leave in to detect substrings.
4784 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
4785 * tags.h: Fix diagrams and comments describing the S tag bit;
4786 remove vestigial remarks about the D tag bit.

4788 * strings.c: Formatting tweaks.
4790 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
4791 variable first; then SCHEME_LOAD_PATH, with a warning message.
4792 (scm_parse_path): New function.
4793 * script.c: Doc fixes.
4795 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
4797 Readline support, from Daniel Risacher.
4798 * readline.c, readline.h: New files.

4802 * Makefile.in: Regenerated.
4803 * scmconfig.h.in: Regenerated, after change to ../configure.
4805 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4807 * gh.h: gh_vector_set -> gh_vector_set_x
4809 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4811 * gh_data.c (gh_vector_set_x): changed name to make it consistent
4812 with the ! -> _x mapping when going from Scheme to C.
4814 1997-10-19 Mark Galassi <rosalia@cygnus.com>
4816 * gh.h (gh_reverse):
4824 (gh_assoc): added these gh_ functions implemented as macros.

4834 (gh_set_cdr_x): added these routines as I go through and try to
4835 complete the picture R4RS functions that should be mirrored in the
4838 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4840 * tags.h (scm_tc7_substring): Changed the comment and code to
4841 conform with the changes below. Folks! We have suddenly two new
4842 free tc7 codes!!! Jummy, jummy!
4844 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>

4906 * gh_test_c.c (c_vector_test): some improvements on the vector
4909 * gh.h (gh_vector): this used to exist but do the wrong thing.
4910 Now it (almost) does the right thing, though it takes a list
4911 instead of the individual arguments. I need to see how it could
4913 (gh_list_to_vector): added this function as a macro. Corresponds
4914 to Scheme's (list->vector ...).
4915 (gh_vector_to_list): added this function as a macro. Corresponds
4916 to Scheme's (vector->list ...).
4918 * gh_data.c (gh_vector_ref): renamed from gh_vref to

4921 resembles the Scheme routines more.
4922 (gh_make_vector): this used to be (stupidly) called gh_vector().
4923 This is the right name, since it does the same thing as the Scheme
4924 (make-vector ...) procedure.
4926 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
4928 * ports.h: #include "libguile/print.h"

4943 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
4945 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
4946 macros should by convention not test for NIMPness.)
4947 (SCM_COERCE_OPORT): Adjust indentation.
4949 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
4950 SCM_NIMP test before SCM_PRINT_STATE_P.

4960 printing: Also output hex code of vtable so that type identity
4961 will be indicated as well.
4962 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
4963 Removed struct_printer_var; Removed struct-vtable-offset;
4964 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
4965 vtable-offset-user): New constants.

4970 the type represented by this vtable.
4972 * print.c (scm_iprin1): Don't print arguments of macro
4973 transformers. (They are always: exp env.); Bugfix: Unmemoize
4974 transformer source with correct environment.
4976 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
4978 Streamlining of call-with-dynamic-root:

4983 (cwdr_handler): New function.
4984 (scm_internal_cwdr): New function to perform the function of cwdr
4985 but take args that are more useful to C code. Also, the handler
4986 is now invoked *outside* of the new dynamic root, like the docs
4987 say. We no longer have to catch absolutely all errors, the caller
4988 is responsible for using a handler that does not throw, if he
4990 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4991 * root.h (scm_internal_cwdr): New prototype.
4993 Even more but risky streamlining:
4995 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4996 allocation of the jumpbuf of a root continuation. The changes
4997 below are controlled by it. They are now deactivated.
4998 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4999 the JMPBUF of the scm_rootcont to NULL before returning.
5001 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
5002 when they are non-NULL.
5003 (scm_gc_mark): Likewise, mark only when non-NULL.
5005 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
5006 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
5008 * gc.c (scm_done_malloc): New function.

5020 (scm_free_print_state): Set `revealed' field to false.
5021 (scm_iprin1): Call user supplied closure printer with
5022 scm_printer_apply. Print in the traditional way when there isn't
5023 one or when it returns #f.
5024 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
5025 Accept a port/print-state pair in addition to just a port.
5026 (scm_prin1): Don't return the print_state to the pool when it has
5028 (scm_printer_apply): Set `revealed' field of print_state to true.
5029 (scm_init_print): Set scm_print_state_vtable.
5030 (print_state_fluid, print_state_fluid_num): Removed.

5035 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
5037 * Makefile.in: Regenerated with automake 1.2c.
5039 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
5041 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
5042 was looping endlessly.
5044 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
5046 * strports.c (scm_eval_string): Don't close the port.
5048 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
5049 former returns a nice normal integer. (Thanks to Daniel
5052 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
5054 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
5055 makefile variable as a build parameter called LIBS. The
5056 build-guile program will use this, for the time being.
5057 * Makefile.in: Regenerated.
5059 Thanks to Shiro Kawai:
5060 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
5061 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
5064 * Makefile.in: Regenerated with automake 1.2a.
5066 * script.c (scm_compile_shell_switches): If we hit the -c or --
5067 arguments, don't set the car of (command-line) to scm_usage_name,
5068 the prettified name of the guile executable; give it the full
5069 path, the way shells usually handle $0.
5071 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5073 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
5074 Scheme-level name `array-map' and renamed `serial-array-map' to
5075 `serial-array-map!'.
5077 * backtrace.c: Introduced exception handlers which now enclose
5078 `display-error' and `display-backtrace' so that error reporting
5079 won't get into infinite loops if an error occurs during displaying
5080 of the error. This can very easily happen with user supplied
5081 print call-back routines.
5083 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5085 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
5086 the names `serial-array-map' and `array-map' should be removed.)
5088 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
5090 * init.c (scm_boot_guile_1): Added scm_init_objects ().
5091 Added #include "objects.h"
5093 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
5094 Add #include "feature.h".
5096 * Makefile.am (libguile_la_SOURCES): Added objects.c.
5097 (modinclude_HEADERS): Added objects.h.
5099 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
5100 This test is needed at many places in the code and should be
5101 abstracted. (Motivated by the need of this test in libguiletk.)
5103 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
5104 (scm_eval_string), load.c (scm_primitive_load,
5105 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
5106 Use SCM_EOF_OBJECT_P.
5108 * eval.c (scm_init_eval): Add feature `delay'.
5110 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5112 * scmhob.h: Removed.
5114 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5116 * list.h (SCM_LISTn): New macros. Make list creation in C code
5117 prettier. The idea comes from STk.
5119 * sequences.h, sequences.c, append.h, append.c: Removed. These
5120 files implemented non-R4RS operations which would encourage
5121 non-portable programming style and less easy-to-read code.
5123 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
5126 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
5127 sequences.h, #include append.h.
5129 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
5132 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
5134 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
5136 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
5138 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5140 * eval.c: Added #include "objects.h"
5142 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
5145 * smob.c (scm_smob_prehistory): Create two objectsmobs with
5146 adjacent smob numbers.
5148 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5150 * procprop.h: Added declaration of scm_i_inner_name.
5152 * gsubr.c: New global symbol scm_i_inner_name.
5154 * debug.c (scm_procedure_name): Try procedure property
5155 `inner-name' if `name' fails.
5157 * print.c (scm_iprin1): Use scm_macro_name.
5159 * eval.c (scm_m_define): Give names to macros as well; Only the
5160 first top-level definition gives a procedure/macro a name.
5161 Otherwise confusing names can turn up in backtraces.
5162 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
5163 `name'; Give names to macros as well.
5165 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
5166 (scm_macro_transformer): Use SCM_CLOSUREP instead of
5169 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5171 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
5173 (prinmacro): Removed. The code has been moved/merged into print.c
5174 in order to decrease code redundancy. We want macros to print in
5175 a way equivalent to procedures, and it would be silly to duplicate
5176 the required code. (We don't want to maintain two places.)
5177 (macrosmob): Print field is now a NULL pointer.
5179 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
5180 scm_macro_transformer): New prototypes.
5181 (scm_tc16_macro): Declared.
5183 * print.c (scm_iprin1): Added code for printing of macros. Macros
5184 are now printed in a way equivalent to procedures.
5186 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
5188 * procs.h (scm_closure_p): Added declaration.
5190 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5192 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
5193 Shouldn't pass "heap" as the subr name.
5195 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
5197 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
5198 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
5199 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
5200 gh_equal_p): Use SCM_NFALSEP, instead of testing against
5201 SCM_BOOL_T. Any non-false value is true.
5203 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5205 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
5206 scm_gensym): Added prototypes.
5208 * symbols.c (scm_gensym): New function. This will speed up
5209 certain types of applications (such as macro systems) which
5210 generate lots of symbols.
5212 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5214 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
5216 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
5218 * unif.c (scm_shap2ra): tighten the checking of the array dimension
5219 specifier, since (2) or (2 . 3) would cause SEGV.
5220 (scm_transpose_array): more argument checking fixes.
5222 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
5224 * Makefile.in: Regenerated.
5226 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
5228 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
5230 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5232 * error.c, error.h (scm_error_callback): Removed (see NEWS).
5234 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
5236 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
5237 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
5240 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
5241 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
5242 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
5243 scm_array_p, scm_array_rank, scm_array_dimensions,
5244 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
5245 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
5246 scm_array_prototype): Added case scm_tc7_wvect.
5248 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
5250 * errno.h: prototype for scm_strerror.
5251 * error.c (scm_strerror): new procedure.
5253 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5255 * list.c (scm_list_append_x): Allow non-pair as last argument.
5256 This is consistent with the R4RS append and is probably the
5257 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
5259 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
5261 * stime.h: prototype for scm_times.
5262 * stime.c (scm_times): new procedure.
5263 * ioext.c (scm_fseek): if the first argument is a file descriptor
5265 (scm_ftell): if the first argument is a file descriptor call lseek
5267 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
5268 * filesys.c (scm_chmod): if the first argument is a file descriptor,
5270 (scm_chown): if the first argument is a port or file descriptor,
5272 (scm_truncate_file): new procedure.
5273 Add DEFER/ALLOW INTS to a few other procedures.
5274 (scm_fsync): new procedure.
5275 (scm_open_fdes): new procedure.
5276 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
5278 (scm_fcntl): the first argument can now be a file descriptor. The
5279 third argument is now optional.
5281 * posix.c (scm_execl, scm_execlp): make the filename argument
5282 compulsory, since omitting it causes SEGV.
5283 (scm_sync): return unspecified instead of #f.
5284 (scm_execle): new procedure.
5285 (environ_list_to_c): new procedure.
5286 (scm_environ): use environ_list_to_c. disable interrupts.
5287 (scm_convert_exec_args): take pos and subr arguments and
5288 improve error checking.
5290 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5292 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
5293 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
5294 argument to SCM_ASSERT. Furthermore, the name of the function
5295 should be passed as first argument when signalling
5296 SCM_WNA. (Thanks to Thomas Morgan)
5298 * gsubr.c (scm_gsubr_apply): From Radey Shouman
5299 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
5300 dispatches on the number of actual args has a default case
5301 reporting an internal error. This is a vestige from a version
5302 that mallocated a SCM vector to hold the arguments. In the
5303 current version this check is too late: if it ever happens we will
5304 have already overstepped the bounds of the array.
5306 Also, the patch [...] adds a check for too many actual arguments."
5308 mdj: Removed check for "internal programming error".
5310 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5312 * gh_io.c (gh_write): New function.
5314 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
5315 throw.c (scm_internal_stack_catch): New sibling to the other catch
5316 functions. Code moved from gh_eval.c.
5317 throw.h: Added header.
5318 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
5319 scm_internal_stack_catch.
5321 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5323 * ioext.h: fix up prototypes.
5324 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
5325 Scheme name is now dup->fdes.
5326 (scm_dup_to_fdes): make the second argument optional and
5327 fold in the functionality of scm_primitive_dup.
5328 (scm_primitive_dup): deleted.
5330 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
5332 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
5333 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
5334 ultrix are defined. Use setvbuf instead of setbuf.
5335 (scm_setvbuf): new procedure.
5336 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
5337 (scm_setfileno): moved from ioext.c.
5338 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
5339 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
5341 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5343 * fluids.c (scm_fluid_p): New function.
5344 * fluids.h (scm_fluid_p): New prototype.

5348 * print.c (scm_iprin1): Enter printed structures into the print
5349 state as nested data while they are printed.
5350 (print_state_fluid, print_state_fluid_num): New variables.
5351 (scm_init_print): Initialize them.
5352 (scm_iprin): If print_state_fluid carries a print_state, use that
5353 instead of creating a new one.
5354 (scm_printer_apply, apply_stub, struct apply_data): New
5355 definitions to help with calling printer functions written in
5357 * print.h (scm_printer_apply): New prototype.
5359 * struct.c (scm_print_struct): Use scm_printer_apply to call the
5360 user defined struct printer.
5362 * dynwind.c (scm_dowinds): Handle fluids on the wind list.

5370 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
5371 SCM_ASSERT: arg comes before pos.
5373 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5375 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
5376 to a list of length zero correctly.
5378 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5380 Supply an `fgets' method for port objects to do fast line i/o.

5392 Mon Jul 21 04:03:42 1997 Gary Houston <ghouston@actrix.gen.nz>
5394 * ioext.h: removed scm_duplicate_port prototype.
5396 * ioext.c (scm_primitive_dup2): return the new file descriptor
5397 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
5399 (scm_fdopen): bug fix: don't try to make port unbuffered until its
5400 stream has been set.
5401 (scm_duplicate_port): deleted, there's now an implementation in
5403 (scm_primitive_dup2): do nothing if newfd == oldfd.
5405 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
5407 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
5410 * ioext.h: new prototypes.
5411 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
5413 * fluids.c (next_fluid_num): don't do
5414 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
5416 * ports.h: prototypes too.
5417 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
5419 * fports.h: prototype too.
5420 * fports.c (scm_evict_ports): moved from ioext.c.
5422 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5424 * ports.c (scm_close_port): return a boolean instead of unspecified.
5425 throw an error if an error other than EBADF occurs.
5427 * filesys.h: scm_close prototype.
5428 * filesys.c (scm_close): new procedure, can close file descriptors
5429 and ports (scsh compatible).
5431 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
5434 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
5436 * fluids.c, fluid.h: New files.
5437 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
5438 (modinclude_HEADERS): Added "fluids.h"
5440 * init.c: Include "fluids.h". (scm_boot_guile_1): Added call to
5441 scm_init_fluids to initialize the fluid machine.
5442 (scm_start_stack): Initialize the fluids of the first root with
5443 scm_make_initial_fluids.

5446 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
5447 (scm_make_root): Call scm_copy_fluids to make fluid bindings
5448 unique for the new root when it has a parent.
5450 * smob.h: Include "libguile/print.h" to make scm_print_state
5453 * dynl.c (free_dynl_obj): New function to free the dynamic object
5454 data. (dynl_smob): Use it.
5455 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
5456 the dynamic object data below the linking of the object to avoid
5457 memory leak when the linking code throws an error. Now the code
5458 leaks a whole dynamically linked library when must_malloc throws,
5459 but that should be much less likely.
5461 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
5463 Changes to compile under gnu-win32, from Marcus Daniels:
5464 * stime.c (tzset): If tzset isn't provided, make it a NOP.
5465 (scm_localtime): Change SCM_EOF to SCM_EOL.
5466 (scm_mktime): Likewise.
5467 * socket.c: Don't include sys/un.h unless autoconf tells
5468 us Unix domain sockets are available.
5469 (scm_fill_sockaddr): Ignore Unix domain code.
5470 (scm_addr_vector): Likewise.
5471 (scm_init_addr_buffer): Likewise.
5472 (scm_socketpair): Don't include unless socketpair was

5475 * scmsigs.c (scm_pause): Don't include unless pause was found
5477 * posix.c (scm_getgroups): Don't include unless support function
5478 was found during autoconf (in this case, getgroups).
5479 (scm_setpwent): For setpwent.
5480 (scm_setegid): For setegid.
5481 * net_db.c (scm_inet_netof): Don't include unless support
5482 function was found during autoconf (in this case, inet_netof).
5483 (scm_lnaof): For inet_lnaof.
5484 (scm_inet_makeaddr): For inet_makeaddr.

5496 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
5497 scm_misc_error, not SCM_EOF.
5499 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
5500 arguments for formatting the error message, not SCM_BOOL_F. I
5501 think this is left over from the (eq? '() #f) days.
5503 * read.c (recsexpr): Give this a dummy definition if
5504 DEBUG_EXTENSIONS isn't #defined.
5506 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
5508 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
5511 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>
5513 * root.c (cwdr_outer_body): Bugfix: Pass `c' instead of `&c' to
5516 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
5518 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
5519 alloca.lo will be included in @LIBLOBJS@. Something better than
5520 this should be possible.
5521 * Makefile.in: Regenerated.
5523 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
5525 * simpos.h: prototype for scm_primitive_exit.
5526 * simpos.c (scm_primitive_exit): new procedure, terminates the
5527 process without unwinding the stack.
5529 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
5531 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
5532 argument and logior its components together, so the user doesn't
5533 have to do this explicitly. Also, if regexp/basic is supplied, then
5534 turn off REG_EXTENDED.
5535 (scm_init_regex_posix): New regexp/basic symbol.
5536 (REG_BASIC): #define this if it is not already present.
5538 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5540 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
5541 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
5542 (CLEANFILES): New target, clean versiondat.h, libpath.h.
5543 (DISTCLEANFILES): New target, clean *.x.
5544 * Makefile.in: Regenerated.

5548 * script.c (scm_compile_shell_switches): Add 1997 to copyright
5549 years in usage message.
5551 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
5552 * Makefile.in: Regenerated.
5554 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
5555 flag; I don't think we support it.
5556 (scm_make_regexp): Make sure the user doesn't pass the
5559 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
5561 (scm_init_regex_posix): Define constants for the REG_mumble flags;
5562 name them according to the SCSH convention: regexp/mumble.
5564 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
5566 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
5568 * Makefile.am (libpath.h): Include the values of all the standard
5569 Makefile directory variables. Print a message, but don't print
5571 (versiondat.h): Print a message, but don't print all the commands.
5572 * load.c: #include "alist.h".
5573 (init_build_info): New function.
5574 (scm_init_load): Call it.
5575 * Makefile.in: Regenerated.
5577 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
5579 * root.c: Establish a reliable catch-all handler for the new root.
5580 After all the Scheme handler function might signal an error too,
5581 and we don't want to lose that.
5582 (cwdr_inner_body): Renamed from cwdr_body.
5583 (cwdr_outer_body): New function, to establish the user's handler,
5584 and pass control to cwdr_inner_body.
5585 (cwdr): Establish the reliable catch-all handler here, and pass
5586 control to cwdr_outer_body.
5587 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
5588 the user's handler through to cwdr_outer_body.
5589 * throw.c (scm_handle_by_message): Move guts into....
5590 (handler_message): New static function.
5591 (scm_handle_by_message_noexit): New function.
5592 * throw.h (scm_handle_by_message_noexit): New prototype.
5594 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
5595 across this. Only works on GCC. Otherwise, we hope for the best.
5596 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
5597 the feeling that real thread systems will not need this...
5599 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
5601 Try to detect when people are using one version of libguile and a
5602 different version of ice-9. People have been skewing things and
5603 sending in bug reports.
5604 * Makefile.am (versiondat.h): New file to generate.
5605 * version.c: #include "versiondat.h", to get version info.
5606 (scm_libguile_config_stamp): New function.
5607 * script.c: #include "version.h".
5608 (scm_compile_switches): Call scm_version to get version number.
5609 * scmconfig.h.in, Makefile.in: Regenerated.
5610 * Makefile.in: Regenerated.
5612 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
5613 primitive definitions under their Scheme names.
5615 * Makefile.am (libguile_la_LDFLAGS): Update library version to
5616 1:2. Helps avoid confusion between installed and uninstalled libs.
5618 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
5621 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
5622 backslash from definition; this should be used like: GDB_INTERFACE;
5624 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5626 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
5627 new port unbuffered until its stream has been set.
5629 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
5631 * ports.h: new prototype.
5632 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
5634 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
5636 Make things compile neatly under Sun's C compiler.
5637 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
5638 * extchrs.c (xmbtowc): Make the second arg a normal char, not
5639 unsigned, because that's what the ANSI function takes.
5640 * extchrs.h (xmbtowc): Corresponding change to prototype.
5641 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
5643 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
5644 argument plain char *.
5645 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
5647 * tag.c (scm_tag): Remove unreachable statement.
5648 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
5649 top of the word, it should be unsigned.
5651 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
5652 is defined, to avoid warnings; it's only used in the
5653 conflict-checking code. Which might go away anyway.
5654 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
5655 conditionals; put the label definition in an #if too, to stifle
5658 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
5659 ChangeLog-threads in the distribution.
5660 * Makefile.in: Regenerated.
5662 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5664 * guile-snarf.in: Changed regexp to support CPPs that insert
5665 whitespace between lexical tokens (which munges the `%%%' snarf
5668 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5670 * load.c (scm_init_load_path): Append $(datadir)/guile to
5671 %load-path, so modules do not have to be installed in Guile's
5672 current version directory.
5674 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
5676 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
5677 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
5678 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
5679 call the sysdep functions with deferred ints.
5680 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
5681 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
5682 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
5685 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
5688 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
5690 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
5692 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
5694 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
5697 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
5699 * eval.c (scm_lookupcar1): New procedure to cope with a race
5700 condition during lookup (when using threads).
5701 (scm_lookupcar): Implement in terms of scm_lookupcar1.
5702 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
5705 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
5707 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
5708 supplied. (Change from Tim Pierce.)
5710 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
5712 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
5713 23:47:01 1997" changelog: Slots are now initialized with `#f' by
5714 default and not `()'. `#f' is the canonical non-value in Scheme,
5717 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5719 * struct.c (struct_printer): New variable that holds a handle on
5720 the Scheme variable *struct-printer*. This variable can be set by
5721 Scheme code to override the printing of structures.
5722 (scm_print_struct): If struct_printer is set, call it. If it is
5723 not set, or returns #f, print the structure in the old fashion.
5724 Include "eval.h" for scm_apply.
5726 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
5728 * struct.c (scm_struct_ref, scm_struct_set_x): Use
5729 scm_struct_i_n_words to get the number of fields, not
5730 -scm_struct_n_extra_words.
5732 On the route to fancier struct printing:
5733 * struct.c (scm_print_struct): New function to print a structure.
5734 Include "genio.h" to support it. This function doesn't do
5735 anything interesting right now, but I think it should be here
5737 * struct.h: Include "print.h" and add prototype for
5739 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
5740 print structures ourself.
5742 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5744 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
5745 before applying the handler in case it doesn't return.
5747 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
5749 * scmsigs.h, async.h: updated.
5751 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
5754 * posix.c (scm_uname): interpret only negative values as an error.
5755 Solaris normally returns a positive value.
5757 * script.c (scm_compile_shell_switches): if we are not going into
5758 an interactive repl, set scm_mask_ints to zero so that asyncs can
5761 * simpos.c (scm_system): don't ignore/unignore signals around
5764 * posix.c (scm_open_pipe): don't ignore/unignore signals around
5767 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
5768 done in boot-9.scm instead.
5770 * scmsigs.c, async.c: Major rewriting of signal handling code.
5771 (scm_sigaction): new procedure.
5772 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
5774 (scm_raise): return unspecified, throw error on failure.
5776 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5778 * regex-posix.c (scm_init_regex_posix): Register the "regex"
5779 feature, to help boot-9.scm decide whether to import the regex
5782 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5784 * eval.c: Include scmconfig.h at the beginning of the file so that
5785 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
5788 * regex-posix.c: #include "_scm.h" before conditionally #including
5789 <regex.h>; the former defines HAVE_REGCOMP.
5791 * regex-posix.c: #include <regex.h> conditionally, so the file is
5792 CPP'able (for dependency scanning) even on systems that don't have
5795 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5797 Add new R4RS-compliant syntax for keywords.
5798 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
5799 regardless of the setting of the `keywords' read option.
5800 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
5801 can be re-read no matter what the setting of the `keywords' read
5804 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
5806 Add support for POSIX regular expressions.
5808 * regex-posix.c, regex-posix.h: New files. (Some code
5809 is taken liberally from rx/rgx.c in the old Guile dist.)
5811 * init.c: Include regex-posix.h.
5812 (scm_boot_guile_1): Call scm_init_regex_posix.
5814 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
5815 Add regex-posix.[ch] sources.
5816 * Makefile.in: Regenerated.
5818 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
5819 to do this automatically? It didn't for me, bleh.)
5821 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
5823 * fports.c (print_pipe_port): New function.
5824 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
5825 latter doesn't even take the right arguments.
5827 * Makefile.am: Increment shared lib revision number. I think
5828 sometimes the uninstalled Guile finds the installed shared lib;
5829 Gord says doing this might help. As things turned out, I can't
5830 say whether it does.
5831 * Makefile.in: Regenerated.
5833 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
5834 passing it as the closure argument to scm_boot_guile. (Bill
5837 * ports.c (print_void_port, putc_void_port, puts_void_port,
5838 write_void_port, flush_void_port, getc_void_port, close_void_port,
5839 noop0): Use ANSI prototypes instead of K&R declarations, so the
5840 initialization of void_port_ptob gets aggressively type-checked.
5841 Fix arguments of print_void_port and write_void_port. (Bill

5875 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
5877 * script.c (scm_find_executable): Use prototype-style definition
5878 here; apparently it's not quite right to have const in a prototype
5879 and then use a K&R declaration. I wonder if stuff like this will
5880 go away if we compile with -Wrequire-prototypes, or whatever that
5881 is... (Bernard URBAN)
5883 * scmhob.h: New text from Bernard URBAN.
5885 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5887 * script.c: Don't #define const on hpux. Configure takes care of
5888 this. (Thanks to Larry Schwimmer.)
5890 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
5891 decide whether to #include <unistd.h>, instead of listing a bunch
5892 of systems. Don't #include stdio twice. Removed dyked-out
5893 definition of scm_find_impl_file.
5895 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5897 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
5898 library version info to 1:0.
5899 * Makefile.in: Regenerated.
5901 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

5905 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
5906 throw.c: Update copyright years; these files have been worked on
5907 significantly in 1997, but only had copyright years for 1996.
5908 Also, change name of copyright holder on some from Mikael
5909 Djurfeldt to Free Software Foundation; he has signed papers
5910 assigning the changes to the FSF.
5912 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
5913 reason not to give the user the option.
5915 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5916 Return #f on end-of-file when scanning table (i.e. when called
5917 with no arguments). Try to catch errors, when we can.
5918 * posix.c (scm_getgrgid, scm_getpwuid): Same.
5920 * script.h (scm_shell_usage, scm_compile_shell_switches): New
5921 external declarations. These are useful.
5923 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
5925 * posix.c: don't include <sys/select.h> or define macros for
5926 select, since they were not used in this file.
5928 * filesys.c (scm_select): make the fifth parameter microseconds,
5929 not milliseconds. let the fourth parameter be either a real value
5930 or an integer or #f. The first, second and third arguments can
5931 now be vectors: the type of the corresponding return set will be
5933 (set_element, get_element): new static procedures.
5935 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
5937 * strports.c (scm_eval_string): New function.
5938 (scm_eval_0str): Trivially re-implemented in terms of
5940 * strports.h (scm_eval_string): New extern decl.
5942 * net_db.c (h_errno): Add extern decl for this.
5944 * fports.c (local_pclose): New function.
5945 (scm_pipob): Use it in the initializer here.
5948 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
5949 Use a meaningful error message when signalling an error. For
5950 this, scm_gethost must check h_errno rather than errno.
5952 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
5954 * Makefile.in: Regenerated, using automake-1.1p.
5956 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5958 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
5959 not SCM_UNSPECIFIED.
5961 * script.c (scm_compile_shell_switches): don't append (quit) if
5963 (scm_shell): call scm_exit_status and exit on the result of the
5966 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
5968 Ensure that shared substrings are handled properly when passed to
5969 a system call or other foreign function. Many thanks to Tim
5971 * symbols.h (SCM_COERCE_SUBSTR): new macro.
5972 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
5973 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
5974 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
5975 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
5976 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
5977 (scm_display_error_message): use RO macros when strings may be RO.
5978 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
5979 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
5980 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
5981 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
5982 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
5983 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
5984 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
5985 scm_strftime), vports.c (scm_make_soft_port): use
5986 SCM_COERCE_SUBSTR to make sure shared substrings are
5989 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5991 * error.c (scm_error): Add newline to error message.
5993 * init.c (scm_init_standard_ports): Doc fix.
5995 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5997 * dynl-shl.c: Completely replaced with new code from Bernard
6000 * script.c (scm_ice_9_already_loaded): New variable.
6001 (scm_compile_shell_switches): Use it.
6003 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
6005 * filesys.c (scm_input_waiting_p): add missing third argument to
6008 * stime.c (scm_localtime): copy the result of localtime before
6009 calling gmtime in case they share a buffer.
6010 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
6013 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6015 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
6017 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
6019 * Makefile.am (check-local): New target, which causes 'make check'
6020 to run gh_test_c and gh_test_repl, with some trivial input.
6021 * Makefile.in: Rgnrtd.
6023 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
6025 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
6028 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
6030 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
6031 sure how this was supposed to work.
6032 (scm_async_click): don't send SCM_TICK_SIGNAL.
6033 (scm_init_async): don't initialize %tick-thunk.
6035 * the following change doesn't affect the Scheme interface:
6036 gc-thunk is called at the end of garbage collection. however it's
6037 no longer implemented by pretending it's a signal.
6039 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
6040 system async corresponding to scm_gc_thunk.
6041 * async.h: declare scm_gc_async.
6042 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
6043 gc-thunk directly, instead of going through a signal handler.
6044 (scm_gc_async): new variable, points to the GC system-async.
6045 (scm_init_async): save the GC async as scm_gc_async instead
6046 of using system_signal_asyncs.
6047 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
6049 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
6051 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
6052 Don't screw up if we're interrupted.
6053 * Makefile.in: Regeneradet.
6055 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
6057 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
6059 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
6060 we're not using AM_INIT_GUILE_MODULE any more.
6061 * Makefile.in: Reneregated.
6063 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
6065 Functions for finding variable bindings, grace à Tim Pierce.
6066 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
6067 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
6069 Get 'make dist' to work again.
6070 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
6071 * Makefile.in: Regenerated, like a surry without a fringe on top.
6073 Changes for reduced Guile distribution: one configure script,
6075 * configure.in, configure: Removed.
6076 * acconfig.h, acinclude.m4: Moved to parent directory, where the
6077 real configure script lives.
6078 * Makefile.in, scmconfig.h.in: Regenerated.
6080 * init.c: #include "script.h", to get prototype for script.c's
6083 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
6085 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
6086 scm_must_malloc, not raw malloc.
6088 * script.c (scm_compile_shell_switches): Dyke out debugging output
6091 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6093 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
6095 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
6096 system has them. Hope this is safe. Previously
6097 sys/timeb.h was included if HAVE_FTIME was defined or if
6098 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
6099 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
6101 * ioext.c (scm_setfileno): add missing third argument to
6102 scm_misc_error call.
6104 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
6106 * eq.c (scm_equal_p): Correctly compare strings of different
6107 varieties. (Thanks to Tim Pierce.)
6109 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
6111 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
6112 #! block comment must occur on a line all by itself.
6114 Move most of the guts of shell command processing into libguile,
6115 so guile.c can be very small (and eventuallly auto-generated. (I
6116 mean, generated mechanically, not self-generated. Hmm.))
6117 * guile.c, script.c, script.h: New source files.
6118 * init.c (scm_boot_guile_1): Call scm_init_script.
6119 * libguile.h: #include "script.h".
6120 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
6121 targets, for new executable.
6122 (libguile_la_SOURCES): Mention script.c.
6123 (modinclude_HEADERS): Add script.h.
6124 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
6125 not dynamic linking is enabled. This is because we're generating
6126 executables now. Move CY_AC_WITH_THREADS call after those, so the
6127 values of cy_cv_threads_libs captures the libs chosen above.
6128 * Makefile.in, configure, aclocal.m4: Regenerated.
6130 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
6131 We don't maintain this interface any more, and it just confuses
6134 * alloca.c: #include <scmconfig.h>, not <config.h>.
6135 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
6136 it'll get included in disties.
6138 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
6140 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
6141 be distributed, because they confuse people.
6142 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
6144 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
6146 * configure.in: check for presence of gethostent (not present on
6147 OpenBSD by default).
6148 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
6149 * configure, scmconfig.h.in: Regenerated.
6151 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
6153 * backtrace.c (scm_backtrace): Split message string across
6154 newlines properly. GCC is more tolerant of this than other
6157 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
6159 Merge threads directory into libguile.
6160 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
6161 threads.h: New source files.
6162 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
6163 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
6165 (modinclude_HEADERS): Add threads.h, coop-defs.h.
6166 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
6167 coop-threads.c.cygnus, coop-threads.h.cygnus.
6168 * configure.in: If we're using threads, include threads.o in
6170 * _scm.h, libguile.h: threads.h lives in this directory now.
6171 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
6172 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
6173 currently used, but brought along for information's sake.
6174 * ChangeLog-threads: log from old 'threads' directory.
6175 * Makefile.in, configure: Rebuilt.
6177 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
6179 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
6182 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
6184 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
6186 Merge GH interface library into libguile.
6187 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
6188 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
6189 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
6190 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
6192 (EXTRA_libguile_la_SOURCES): ... here.
6193 (pkginclude_HEADERS): Add variable, to get gh.h installed.
6194 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
6195 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
6196 New variables, describing how to build the gh test programs.
6197 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
6198 build the test programs, and we probably should have been linking
6199 libguile.la against them all along, to support AIX shared libs.
6200 Add cflags for threads to CFLAGS; add libs for threads to new
6201 variable THREAD_LIBS, used in Makefile.am.
6202 * ChangeLog-gh: log from old `gh' subdirectory.
6203 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
6205 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
6207 * acconfig.h: Undo change of Apr 9; including the definition of
6208 PACKAGE in the guile headers conflicts with applications' own
6210 * scmconfig.h.in: Regenerated.
6212 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

6215 (scm_init_filesys): New symbols for use with fcntl.
6216 * filesys.h: Added prototype.
6218 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
6219 when PROC is receiving no arguments.
6221 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
6223 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
6224 have S_IFSOCK. This is the case under Ultrix.
6226 * posix.c (scm_status_exit_val, scm_status_exit_val,
6227 scm_status_term_sig, scm_status_stop_sig): Modified to work with
6228 Ultrix versions of WIFSTOPPED, etc., which assume that their
6229 arguments are lvalues (hmm).
6231 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
6233 * eval.c: Doc fixes.
6235 * throw.c: Doc fixes; rearranged.
6237 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
6239 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
6241 * acconfig.h: Added entry for PACKAGE.
6242 * scmconfig.h.in: Regenerated.
6244 Changes to work with automake-1.1n, which has better libtool support.
6245 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
6246 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
6248 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
6250 * Makefile.in: Rebuild.
6252 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6254 * stime.c (scm_mktime): take an optional zone argument.
6255 (scm_localtime): check putenv return value.
6256 (scm_strftime, scm_strptime): moved from posix.c. move #include
6258 stime.h, posix.h: update prototypes.
6259 (bdtime2c, setzone, restorezone): new static procedures.
6260 (scm_mktime, scm_strftime): use them.
6261 (scm_strftime): don't call mktime before strftime. Use
6262 filltime for return value.
6263 (filltime): convert NULL zname to #f.
6264 (scm_strptime): return a count of characters consumed, not
6265 the remaining string.
6267 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6269 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
6270 (scm_mktime): likewise.
6272 Uncomment localtime and mktime.
6274 * configure.in: add AC_STRUCT_TIMEZONE.
6276 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
6278 * stime.c (scm_init_stime): don't define ticks/sec.
6279 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
6280 return value problem and is still portable.)
6282 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6284 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
6285 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
6286 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
6287 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
6288 cpp_err_symbols.c): Corresponding changes.
6289 * Makefile.in: Regenerated.
6291 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6293 * posix.c (scm_putenv): don't check HAVE_PUTENV.
6294 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
6295 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
6296 * putenv.c: new file, from sh-utils 1.12.
6298 * posix.c (scm_environ): use malloc in place of scm_must_malloc
6299 since allocation isn't for Scheme objects.
6300 (scm_putenv): copy strings before placing in the environment.
6302 * stime.c (scm_current_time): throw an error if time returns -1,
6303 instead of returning #f.
6304 (scm_get_internal_real_time, scm_get_internal_real_time): use
6305 scm_long2num for return value instead of SCM_MAKINUM.
6307 * stime.h: prototypes updated.
6309 * stime.c (scm_time_in_msec): apparently unused, deleted.
6311 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
6313 * configure.in: check for gettimeofday.
6315 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
6316 which may be more usefully portable than a gettimeofday interface.
6318 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
6320 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
6322 * Makefile.in: Regenerated.
6324 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6326 * stime.c (filltime): recovered static procedure.
6327 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
6330 * posix.h: add prototype for scm_close_pipe, remove prototypes for
6331 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
6333 * posix.c (scm_mknod): split the mode argument into type and perms
6334 arguments, like the extra fields returned by stat.
6336 * fports.c (scm_pipob): set the close, free and print procedures.
6337 (scm_close_pipe): new procedure.
6339 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
6340 define them in boot-9.scm
6342 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6344 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
6345 wan't defined. Don't include fd.h.
6347 * Previously fd.h was regenerated whenever configure was run,
6348 forcing a couple of files to be recompiled.
6350 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
6351 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
6352 Check for _fileno as well as _file.
6354 * ioext.c: don't fd.h.
6355 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
6358 * Change the stratigy for getting information about errno
6359 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
6360 generating lists of symbols during the build process, which will
6361 not always work, include comprehensive lists in the distribution.
6362 To help keep the lists up to date, the "check_signals" and
6363 "check_errnos" make targets can be used.
6365 * configure.in: don't check for a command to extract errno codes.
6366 * Makefile.am: update file lists, remove errnos.list and errnos.c
6367 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
6368 check_errnos targets.
6369 (CLEANFILES): remove errnos.c and errnos.list, add
6370 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
6371 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
6372 * errnos.default: deleted.
6373 * cpp_signal.c: new file.
6374 * cpp_errno.c: renamed from errnos_get.c.
6375 * cpp_err_symbols, cpp_sig_symbols: new files.
6376 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
6377 * error.c (scm_init_error): #include cpp_err_symbols instead of
6379 * posix.c (scm_init_posix): don't intern signal symbols. #include
6382 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
6384 * strop.c (scm_i_index): allow the lower bound to be equal to the
6385 length of the string, so a null string doesn't always give an error.
6387 * posix.h: new prototypes.
6388 * posix.c (scm_status_exit_val, scm_status_term_sig,
6389 scm_status_stop_sig): new functions, as in scsh. They break down
6390 process status values as returned by waitpid.
6392 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
6394 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
6395 configure doesn't know about it.
6397 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6399 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
6401 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
6402 which defines C variables with global linkage.
6404 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6406 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
6409 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
6411 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
6412 has time to check why this doesn't work well with continuations.
6414 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
6416 * Fix shell syntax error; some shells won't tolerate
6417 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
6419 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
6421 * posix.c (scm_uname): throw an error if uname fails instead
6424 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
6426 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
6429 * async.c (scm_ints_disabled): definition moved from error.c.
6431 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6433 * acconfig.h: Removed PACKAGE.
6435 * scmconfig.h.in: Regenerated.
6437 * snarf.h: g++ says it's non-portable not to specify the first
6438 argument in a varargs declaration. I introduced the first
6439 argument by using preprocessor conditionals.
6441 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
6443 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
6444 (scm_freopen): use RO string macros for filename and modes.
6445 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
6447 * posix.c (scm_getgrgid): simplify conversion of name to C string.
6448 (scm_mknod): use RO string macros for path.
6450 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
6451 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
6453 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
6454 use SCM_ROSTRINGP and SCM_ROCHARS.
6456 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6458 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
6461 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
6462 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
6463 support for byte vectors.
6465 * print.c (scm_iprin1): Limit number of vector elements printed
6466 according to pstate->length.
6468 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6470 * backtrace.c (scm_display_error_message): don't segv if message
6473 * error.h: prototype for scm_error_scm.
6475 * error.c (scm_error_scm): new procedure, reimplements scm-error
6476 in C and uses scm_error.
6478 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6480 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
6481 pointer to the Scheme variable read-hash-procedures and intern it
6482 in scm_init_read. Modify scm_read_hash_extend and
6483 scm_get_hash_procedure to use the pointer.
6485 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6487 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
6488 (SCM_KEYWORD_STYLE): defined.
6490 * read.c (scm_read_opts): add a keywords option. This isn't a
6491 boolean option, in case someone wants to add support for DSSSL
6493 Setup scm_keyword_prefix symbol.
6494 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
6496 I've left keyword support disabled by default, since it doesn't
6497 seem to break the module system and it gives R4RS standard behaviour.
6498 It can be reactivated with (read-set! keywords 'prefix).
6500 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6502 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
6503 before constructing arbiter.
6505 * eval.c (scm_m_define): Bugfix: Check that the object is a
6506 closure before setting the procedure property!
6508 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
6510 * ports.c: Removed `ungetc-char-ready?'.
6512 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
6514 * read.c (scm_init_read): intitialise scm_read_hash_procedures
6515 (idea from Mikael: make it a pair so scm_permanent object only
6517 (scm_read_hash_extend): don't call scm_permanent_object.
6518 (ideas from Mikael): if chr is already in the list, replace its
6519 procedure instead of appending it again. If proc is #f, remove
6521 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
6523 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
6525 * gdbint.c (gdb_read): update scm_lreadr usage.
6527 * load.h: update prototypes.
6529 * load.c (scm_primitive_load, scm_read_and_eval_x,
6530 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
6532 * read.h: add prototype for scm_read_hash_extend. Change args for
6535 * read.c (scm_read_hash_procedures): new variable.
6536 (scm_read_hash_extend): new procedure.
6537 (scm_get_hash_procedure): new procedure.
6538 (scm_lreadr): use scm_get_hash_procedure instead of an argument
6539 for extended # processing.
6540 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
6541 scm_read_token): remove case_i, sharp arguments. Change callers.
6543 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
6545 * read.h (SCM_N_READ_OPTIONS): increase to 3.
6546 (SCM_CASE_INSENSITIVE_P): define.
6548 * read.c: add case-insensitive option to scm_read_opts.
6549 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
6550 to determine whether to convert symbol case.
6551 (default_case_i): definition removed.
6552 * read.c (scm_read_token): if case_i, downcase ic before doing
6555 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6557 * configure.in: Added configuration option `guile-debug'.
6558 Configure with --enable-guile-debug if you want a bunch of extra
6559 functions used for debugging when developing Guile.
6561 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
6563 * procs.c (make-cclo): New undocumented debugging procedure: Make
6564 compiled closure with internal procedure PROC and length LENGTH.
6565 Only compiled if GUILE_DEBUG is defined.
6567 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
6569 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
6571 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
6573 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
6574 with 3 or more args internally to the evaluator.
6576 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6578 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
6579 with 3 or more args internally to the evaluator. This is mainly
6580 because we don't want to pass entry and exit points of the
6581 debug support twice, but it also seems to increase the speed of
6582 the evaluator for such calls (e. g. (+ 1 2 3)).
6584 * backtrace.c (scm_display_application): New procedure:
6585 display-application; Set fancy printing parameters individually
6586 for different types of display (backtrace, error, application).
6587 (These should of course be customizable!)
6589 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
6590 clear the CHECK-flags.
6592 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6594 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
6596 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6598 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
6599 from pairs with a GLOC in the car.
6601 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
6602 otherwise `symbol-hash' will behave badly.
6603 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
6604 we get segmentation fault!
6606 * symbols.c: Added #include "weaks.h". New functions:
6607 `builtin-bindings' and `builtin-weak-bindings'. (These will be
6608 moved to an extraneous library when we split libguile.)
6610 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6612 * filesys.c (scm_stat): stat now takes fport arguments too as
6613 documented in the manual.
6615 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6617 * debug.c (scm_single_step): Bugfix: Call continuation with
6618 scm_call_continuation instead of throwing to it.
6620 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
6622 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
6623 argument wasn't declared to be optional.
6625 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6627 * stime.c (scm_init_stime): Add feature "current-time".
6629 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6631 * throw.h: prototype for scm_exit_status.
6632 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
6633 args to derive an exit status. Allows (quit) to work from a
6635 (scm_exit_status): new function.
6638 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6640 * eval.c (scm_deval): Removed some old code.
6641 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
6643 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
6646 * symbols.c (msymbolize): Bugfix: Must initialize property list to
6649 * procs.c: Introduce the existent C function scm_thunk_p at the
6650 Scheme level as well.
6652 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6654 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
6655 used from C to easily lookup the value of a symbol in the current
6658 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6660 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
6661 scm_init_unif in this file. This will also fix a previous problem
6664 * configure.in: Added AM_MAINTAINER_MODE
6666 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6668 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
6671 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6673 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
6674 source files that are not always included in libguile but should
6675 have their dependencies calculated by automake. This variable is
6676 recognized by automake, no further magic is needed.
6677 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
6678 to deal exclusively with *.lo files, as it seems. The *.o files
6679 are built automatically when the corresponding *.lo file gets
6682 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
6684 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
6687 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
6689 * unif.c (scm_array_set_x): minor change to argument error checking.
6691 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
6693 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
6694 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
6695 They should only be included in the library at configure.in's
6697 (libguile_la_LDADD): Include the appropriate .lo files here.
6698 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
6699 so we know when to build them (and their .lo bretheren).
6700 * configure.in (LIBLOBJS): New substituted variable. We let
6701 configure decide which .o files to include in LIBOBJS, and then
6702 put the corresponding list of .lo files in LIBLOBJS. The latter
6703 is what we pass to libtool.
6704 * Makefile.in, configure: regenerated.
6706 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
6708 * symbols.c (scm_sysintern0): New function. Contains the core of
6709 old scm_sysintern but doesn't take a second value argument.
6710 (scm_sysintern): Now uses scm_sysintern0.
6711 (scm_sysintern_no_module_lookup): Renamed to
6712 scm_sysintern0_no_module_lookup and doesn't take a second value
6713 argument any longer.
6715 * symbols.h (scm_sysintern0: Added declaration.
6717 * options.c (scm_init_opts): Use scm_sysintern0 instead of
6718 scm_sysintern when interning option keys. Otherwise we risk
6719 destroying the values of already interned variables.
6721 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
6722 scheme-level boolean (use SCM_NFALSEP).
6724 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
6726 (scm_backtrace): New function. (C version of old function from
6727 boot-9.scm) Motivation: Make it possible to display backtraces
6728 without depending on boot-9.scm. (I'm uncertain if this
6729 motivation is good enough...)
6731 * root.h (scm_root_state): Add member the_last_stack_var.
6732 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
6734 * root.c (mark_root): Mark scm_the_last_stack_var.
6736 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
6739 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
6741 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
6742 1. mark_lazy_catch didn't mark the smob.
6743 2. Both functions above have standard variants:
6744 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
6745 free_lazy_catch --> scm_free0.
6747 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
6749 * throw.c (scm_internal_lazy_catch): New function.
6750 (scm_lazy_catch): Rewritten to use it.
6751 (scm_ithrow): Handle the new lazy catch representation.
6752 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
6753 that doesn't have a jmpbuf is a lazy catch clause.
6754 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
6755 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
6756 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
6758 (scm_init_throw): Register the new lazy-catch smob type.
6759 * throw.h (scm_internal_lazy_catch): decl for new function.
6761 * throw.c (scm_internal_catch): Doc fixes.
6763 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
6764 configure.in. Including this might cause problems if applications
6765 that link against libguile include their own copies of alloca, but
6766 if they're using autoconf, they should be adding libguile to LIBS
6767 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
6768 the copy in libguile, and things will be okay. (I think.)
6770 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6772 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
6774 strop.h: move prototypes too.
6776 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6778 * posix.c (scm_init_posix): don't intern EINTR since it's now done
6781 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
6782 etc. I deleted them from filesys.c long ago, but didn't
6783 notice they were here too (although ineffective since
6784 sys/stat.h wasn't included).
6786 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
6788 * eval.c: Don't define alloca in GCC case. gcc will automatically
6789 use __builtin_alloca if appropriate.
6791 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
6793 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
6794 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
6795 that values of automatic variables are preserved. See comments
6796 for safe_setjmp for details.
6798 Change from Thomas Morgan:
6799 * variable.c: Include eq.h.
6800 (var_equal): New function.
6801 (variable_smob): Use var_equal as the discriminator for variables.
6803 * throw.c (s_throw): Remove extraneous declaration.
6805 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
6806 * eval.c: Add necessary CPP cruft to support that.
6807 * configure, Makefile.in, scmconfig.h.in: regenerated.
6809 Change from Thomas Morgan:
6810 * procprop.c (scm_procedure_properties): Convert the Scheme
6811 boolean returned by scm_procedure_p into a C boolean before using
6812 it as a condition for SCM_ASSERT.
6813 (scm_procedure_property): Likewise.
6815 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
6816 indications of Unixness.
6819 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6821 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
6823 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6825 * read.c (scm_lreadr): use scm_misc_error to improve one of the
6826 "unknown # object" error messages.
6828 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
6829 (scm_i_index) and declare it static. Add a 'direction' argument
6830 to indicate what way the search should go.
6831 (scm_i_index): throw out-of-range error instead of wrong-type-arg
6833 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
6834 strop.h: remove scm_i_index, scm_i_rindex prototypes.
6836 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6838 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
6840 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
6841 to avoid clash with various scsh forks.
6843 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
6845 The following two changes (ramap.c, throw.c) are motivated by the
6846 apparent unportability of forward declarations of static arrays of
6847 the form `static foo bar[];'.
6849 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
6850 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
6852 * throw.c (scm_throw): Moved above scm_ithrow.
6854 * options.h: Removed the extern declarations of scm_yes_sym and
6855 scm_no_sym since these are static.
6857 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6859 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
6861 * Makefile.am: remove AWK=@AWK@.
6862 Add a rule for generating errnos.list.
6863 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
6865 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
6866 don't extract errnos, just set a variable (avoids the
6867 need to recompile error.c just because configure is run.)
6869 * unif.h: update prototypes.
6870 * unif.c (scm_uniform_array_read,write): change the offset and
6871 length arguments to start and end, for consistency.
6873 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
6875 * ioext.h: update prototypes.
6876 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
6877 scm_read_line_x, it's a more general procedure using an
6878 interface from scsh. read-line and read-line! are now defined
6880 Note that the new read-line trims the terminator
6881 by default, previously it was appended to the returned string. An
6882 optional argument specifies how to process the terminator (scsh
6883 compatible). For the old behaviour: (read-line port 'concat).
6884 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
6885 returns a pair, but is converted to multiple values if the scsh
6888 socket.h: update prototypes.
6889 * socket.c (scm_recvfrom): for consistency with other procedures,
6890 take start and end as separate optional arguments.
6891 (scm_recv, scm_recvfrom): don't allow the second argument
6892 to be a size, only a buffer. Change the scheme names to
6893 recv! and recvfrom!. Don't return the buffer.
6895 * ioext.h, posix.h: move prototypes too.
6896 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
6897 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
6898 "read.h" and "unif.h".
6899 * ioext.c: include "chars.h"
6901 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
6903 * dynl.c: The dynamic linking and module registration functions
6904 are now defined even when dynamic linking is not available for the
6905 host system. Some of their functionality can be done without
6906 dynamic linking; when it's really needed, they throw errors.
6908 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
6910 * configure.in: Only define DYNAMIC_LINKING when one of the system
6911 dependent functions is detected.
6912 * dynl.c (scm_dynamic_func): New function to get the address of a
6913 function in a dynamic object.
6914 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
6915 produced by scm_dynamic_func as the thing to call.
6917 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
6919 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
6920 (scm_register_module_xxx, scm_registered_modules,
6921 scm_clear_registered_modules): New functions.
6923 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
6925 * symbols.c (scm_sysintern): Renamed to
6926 scm_sysintern_no_module_lookup.
6927 (scm_sysintern): New function to take the place of the old
6928 scm_sysintern. It uses the current toplevel lookup closure to give
6929 the symbol its value. This is a temporary hack to put packages
6930 like gtcltk into their own module.
6931 (scm_can_use_top_level_lookup_closure_var): New variable to tell
6932 us whether `scm_top_level_lookup_closure_var' has been initialized
6934 * eval.c (scm_init_eval): Set it.
6936 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6938 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
6939 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
6941 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
6943 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
6944 scm_sys_dup): deleted: FD capability will be added to other
6946 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
6947 scm_fd_free, fd_smob, scm_intern_fd.
6948 (scm_open): renamed from scm_sys_open. Return a port instead of
6949 an FD object. Make the mode argument optional.
6950 (scm_sys_create): deleted, it's just a special case of open.
6951 (scm_init_filesys): move interning of constants O_CREAT etc.,
6952 here (were previously using SCM_CONST_LONG macro).
6953 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
6955 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
6956 include "fports.h" and <stdio.h>
6957 (scm_stat, scm_select): don't support FD objects.
6959 * error.h: adjust scm_syserror_msg prototype.
6960 * error.c (scm_syserror_msg): take an extra argument for errno.
6961 Using the global value didn't always work, since it could be
6962 reset by procedure calls in the message or args arguments.
6964 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
6965 I don't understand why the check was there (and what about the
6968 * strop.c (scm_string_copy): allow shared substrings to be copied.
6970 * unif.h: corresponding change to prototypes.
6971 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
6972 recognize two new optional arguments: offset and length. Allow
6973 the port argument to be an integer (file descriptor, for scsh).
6974 Include <unistd.h> for "read" prototype.
6976 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6978 * socket.c: don't include filesys.h.
6980 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6982 * Makefile.am: add AWK=@AWK@ (?)
6984 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6986 Add a rule to generate errnos.c from errnos.
6987 * error.c (scm_init_error): include errnos.c.
6988 * errnos_cnvt.awk: new file, converts the list of errno codes to
6990 * errnos_get.c: new file.
6991 * errnos.default: new file, contains errnos to try if they can't
6992 be extracted from errno.h.
6993 * configure.in: if using GCC, try and extract errno codes from
6997 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6999 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
7000 * Makefile.am: Made libguile into a libtool library.
7001 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
7002 Set libtool_libs to indicate that libguile is a libtool library.
7003 See guile/ChangeLog for details.
7004 * .cvsignore: ignore "*.lo", the libtool library objects.
7006 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
7008 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
7009 use htons in getservbyport argument.
7011 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
7013 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
7014 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
7017 * objprop.c (scm_object_property): No need to take the CDR of the
7018 value returned by scm_object_properties, since Aug 20 change.
7020 * configure.in: When checking for struct linger, #include
7021 <sys/types.h> as well as <sys/socket.h>. I've never known
7022 <sys/types.h> to cause any portability problems, and Solaris's
7023 <sys/socket.h> needs it.
7024 * configure: Rebuilt.
7026 I think the Sun compiler has chosen a perverse way to interpret
7027 ANSI declarations combined with K&R definitions. We'll
7028 appease it a little bit. But when it invades France, we fight.
7029 * print.c (scm_iprlist): Change 'tlr' argument to an int.
7030 * print.h (scm_iprlist): Here too.
7031 * numbers.c (scm_divbigdig): Change definition to match
7032 declaration in numbers.h.
7033 * unif.c (scm_makflo): Change definition to match declaration in
7036 * init.c (scm_boot_guile): Don't return the value of
7037 scm_boot_guile_1. This function doesn't return a value;
7038 scm_boot_guile_1 doesn't return a value (or return at all).
7040 * eval.c (unmemocopy): Add a semicolon to appease the Sun
7043 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
7044 compile. I have a feeling this function is a bad idea anyway ---
7045 one should always test for features, not systems.
7047 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
7048 semicolons. Only pure luck kept this from being noticed earlier.
7050 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
7052 * socket.c (scm_recvfrom): Added missing semicolon.
7054 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
7056 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
7057 the buffer and start and end positions for scsh networking
7060 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
7062 * configure.in: Revert previous change to this file; the problem
7063 is due to transient automake weirdness.
7064 * configure: Rebuilt.
7066 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
7067 PLUGIN/guile.libs. configure generates the latter from the former.
7068 * Makefile.in: Rebuilt.
7070 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
7071 need this if we install scripts, like guile-snarf.
7072 * configure: Rebuilt.
7074 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
7076 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
7078 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
7080 * socket.c (scm_addr_vector): fix faulty scm_listify.
7082 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
7084 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
7085 style block comment is no longer considered an error.
7087 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
7089 * PLUGIN/guile.libs.in: New file.
7090 * PLUGIN/guile.libs: Removed from repository.
7091 * configure.in: Create PLUGIN/guile.libs from
7092 PLUGIN/guile.libs.in. This is for including additonal libraries
7093 needed for dynamic linking.
7094 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
7095 instead of PLUGIN/guile.libs.
7097 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
7099 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
7101 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
7102 occurrences of the given element from the list, not just the
7103 first. This is how the Emacs Lisp functions behave, how the
7104 analogous Common Lisp functions behave, and (I believe) how the
7105 older Maclisp functions worked. I realize that this change may
7106 break code, but it seemed better to break it before the Guile
7109 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
7110 Their prototypes were already present in gc.h, but they weren't
7112 (scm_init_storage): Initialize scm_protects.
7113 * root.c (scm_protects): New element of scm_sys_protects.
7115 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
7117 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
7119 * libguile.h: Added #include "libguile/net_db.h".
7121 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
7122 30 change. That file is only meant for communication between the
7123 configuration process and load.c. If code linked against libguile
7124 wants to get at the paths mentioned in libpath.h, it can call
7125 functions declared in load.h.
7127 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7129 * libguile.h: Removed #include "libguile/fdsocket.h"
7131 * net_db.c: Added #include <sys/socket.h>.
7133 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
7135 * filesys.c (scm_input_waiting_p): use select in preference to
7136 FIONREAD, since the latter doesn't detect EOF.
7137 Throw error if neither select nor FIONREAD available.
7139 * socket.c (scm_connect): take a port, not a fd object.
7140 (scm_fill_sockaddr): throw an error if fam is not recognised.
7141 (scm_bind): use scm_fill_sockaddr.
7142 (scm_listen): take a port, not a fd object.
7143 (scm_accept): take and return a port. return #f in the car if
7144 address can't be got
7145 (scm_sock_fd_to_port): new procedure.
7146 (scm_socket): use scm_sock_fd_to_port.
7147 (scm_addr_vector): throw error if unrecognised address type.
7148 take an extra argument with the calling procedure name.
7149 (scm_getsockname): take a port. return #f if address can't be got.
7150 (scm_getpeername): take a port. return #f if address can't be got.
7151 (scm_recvfrom): take a port. return #f for address component if can't
7153 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
7154 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
7156 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
7158 * throw.c (scm_internal_catch): Make body funcs and handler funcs
7159 use separate data pointers, to allow them to be designed
7160 independently and reused.
7161 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
7162 Renamed from catch_body, catch_handler, and uncaught_throw; made
7164 (struct scm_catch_body_data): Renamed from catch_body_data; moved
7166 (scm_catch): Use the above.
7167 (scm_throw): Don't bother printing a message for an uncaught
7168 throw; we establish a default handler in init.
7169 * throw.h (scm_internal_catch): Prototype updated.
7170 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
7172 (struct scm_body_thunk_data): New structure, used as data
7173 argument to scm_body_thunk.
7174 * init.c (struct main_func_closure): New structure, packaging up
7175 the data to pass to the user's main function.
7176 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
7177 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
7178 scm_internal_catch to establish a catch-all handler, using
7179 scm_handle_by_message. This replaces the special-case code in
7181 (invoke_main_func): Body function for scm_internal_catch; invoke
7182 the user's main function, using the main_func_closure pointer to
7183 decide what to pass it.
7184 * root.c (struct cwdr_body_data): Remove handler_proc member.
7185 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
7186 (cwdr_handler): Removed.
7188 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
7190 * socket.h (SCM_P): update bind prototype.
7191 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
7192 include "feature.h".
7193 (scm_socket): return a port, not a file descriptor object.
7194 include "fports.h" and <unistd.h>
7195 (scm_bind): take a port, not a file descriptor object.
7196 take an extra argument for address args.
7198 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
7199 INADDR_NONE, INADDR_LOOPBACK.
7201 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
7203 * init.c: include net_db.h and not fdsocket.h.
7204 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
7206 * Makefile.am: corresponding changes.
7207 * socket.h: renamed from fdsocket.h, fix names.
7208 * net_db.h: renamed from socket.h, fix names.
7209 * socket.c: renamed from fdsocket.c.
7210 remove _sys from procedure names.
7211 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
7212 add "socket" to features list.
7213 * net_db.c: renamed from socket.c.
7214 remove _sys from procedure names.
7215 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
7216 add "net-db" to features list.
7217 include "net_db.h". don't include <sys/socket.h> or
7220 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7222 * tags.h (scm_tags): Removed comma at end of last enumerator.
7224 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
7226 Don't use GCC extensions to allocate space for debugging frames.
7227 (Here he goes again! Why do we put up with this?!)
7228 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
7229 an scm_debug_info structure, not an in-line array of them. Add
7230 'info' member, to say how many vect elements we've used, for eval
7232 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
7233 a new variable debug_info_end to mark the end of vect, instead of
7234 the address of the 'info' pointer itself.
7235 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
7236 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
7237 (SCM_APPLY): Explicitly allocate space for debug.vect.
7238 * debug.c (scm_m_start_stack): Same, for vframe.vect.
7239 * stacks.c: Adjusted for new debug frame structure.
7240 (RELOC_INFO, RELOC_FRAME): New macros.
7241 (stack_depth, read_frames): Use them, and new scm_debug_frame
7242 element 'info', instead of magically knowing that eval frames have
7243 an info pointer sitting after vect.
7244 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
7246 (scm_init_stacks): Formatting tweaks.
7248 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
7250 Give GCC more control flow information, so it can be sure that
7251 variables aren't used uninitialized.
7252 * error.h (scm_error, scm_syserror, scm_syserror_msg,
7253 scm_sysmissing, scm_num_overflow, scm_out_of_range,
7254 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
7255 scm_misc_error): Tell GCC that these functions never return.
7256 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
7257 out the field type, call abort if SCM_ASSERT returns, to placate
7259 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
7260 scm_wta ever returns. We can't handle this case anyway, and this
7261 gives the optimizer more information.
7262 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
7263 scm_wta ever returns.
7265 In some cases, the code is fine, but GCC isn't smart enough to
7266 figure that out; this usually happens when one variable is only
7267 initialized and used when a particular condition holds true, and
7268 we know that condition will never change within a given invocation
7269 of the function. In this case, we simply initialize the variables
7270 to placate the compiler, hopefully to a value which will cause a
7271 crash if it is ever actually used.
7272 * print.c (scm_iprin1): Initialize mw_pos.
7273 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
7274 * throw.c (scm_ithrow): Initialize dynpair.
7275 * unif.c (scm_uniform_vector_ref): Initialize cra.
7276 * struct.c (init_struct): Initialize prot.
7277 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
7279 * strports.c (scm_eval_0str): Don't return uninitialized garbage
7280 if EXPR contains no expressions.
7282 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
7284 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
7285 cause an infinite loop (???). So much for the algebraic
7286 equivalency of variable-sized arrays and alloca...
7288 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
7290 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
7291 a SCM boolean, not a C boolean.
7293 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
7295 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
7296 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
7297 rules for raising scm_mtrigger. Previously, unfortunate but not
7298 unlikely circumstances could result in almost constant invokation
7299 of the gc. Now, this situations should be less likely, but they
7300 are not prevented completely.
7302 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
7304 * numbers.c (scm_fuck): Procedure removed; looks like old test
7306 * numbers.h: Prototype removed.
7308 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
7310 * debug.h (scm_debug_frame): Change `vect' member from an in-line
7311 array to a pointer, to match my Nov 21 change in eval.c.
7313 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7315 * libguile.h: Added #include "libguile/backtrace.h", #include
7316 "libguile/stacks.h".
7318 * strings.c (scm_string scm_make_string scm_string_ref
7319 scm_string_set_x scm_string_equal_p scm_string_append):
7320 Bugfix according to scm patch from Aubrey Jaffer:
7321 Corrected long-standing
7322 (not (eqv? (integer->char 128)
7323 (string-ref (make-string 1 (integer->char 128)) 0)))
7324 bug found by John Kozak <jk@noontide.demon.co.uk>.
7326 * strports.c, strports.h: Make scm_eval_0str return the value of
7327 the last expression evaluated (previously, it returned void).
7329 * strports.c, strports.h: New function: scm_read_0str. Does what
7332 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7334 * simpos.c (scm_getenv): return #f if string can't be found in the
7335 environment instead of throwing an exception, for compatibility
7336 with numerous other systems.
7338 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
7340 * Makefile.am (.c.x): Use guile-snarf.
7341 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
7343 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
7345 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
7347 * backtrace.c (scm_display_error_message): Made non-static, and
7348 renamed from display_error_message.
7349 * backtrace.h (scm_display_error_message): Added extern decl.
7350 * throw.c (uncaught_throw): Use it to display the error message.
7352 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
7354 * inet_aton.c: Use #if 0, not #ifdef 0.
7356 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
7358 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
7359 to convert the returned value.
7360 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
7361 the offset argument.
7363 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
7365 Add new interface to catch/throw, usable from C as well as
7367 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
7368 (scm_internal_catch): New function, replaces...
7369 (scm_catch_apply): Deleted.
7370 * throw.c (scm_catch_apply): Deleted; replaced with a more general
7371 mechanism which is a bit more code, but can be used nicely from C
7372 and implement the Scheme semantics as well.
7373 (scm_internal_catch): This is the replacement; it's named after
7374 the analogous function in Emacs.
7375 (scm_catch): Reimplemented in terms of the above.
7376 (struct catch_body_data, catch_body, catch_handler): New
7377 functions, used by scm_catch.
7378 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
7379 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
7380 support for new cwdr.
7382 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
7385 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
7387 * acconfig.h: Added DYNAMIC_LINKING symbol.
7388 * configure.in: Add option and checks for dynamic linking.
7389 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
7390 dynl.h: New files for dynamic linking support.
7391 * Makefile.am (libguile_a_SOURCES):
7393 (modinclude_HEADERS): Added "dynl.h".
7394 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
7396 * init.c (scm_boot_guile_1): Call
7397 scm_init_dynamic_linking to initialize dynamic linking support.
7399 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
7401 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
7402 (as we Schemers say). It needs to be global, so that I can tweak
7403 it for the proper operation of unexec.
7404 (scm_boot_guile_1_live): New variable, see above.
7406 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
7408 * guile-snarf.sh: Removed.
7409 * PLUGIN/guile.libs: Added dependency for -lm.
7410 * acinclude.m4: Renamed from aclocal.m4.
7411 * PLUGIN/greet: Removed.
7412 * Makefile.am, aclocal.m4: New files.
7413 * configure.in: Updated for Automake.
7415 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
7417 * eval.c (scm_definedp): Use top_level_lookup_closure_var
7418 and not top_level_lookup_thunk_var.
7420 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
7422 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
7424 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
7426 * eval.c (scm_definedp): Incompatibly changed to be a builtin
7427 Scheme function, instead of syntax. Single argument is now a
7430 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7432 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
7433 scm_ra_divide): Properly terminate statements passed as arguments
7434 to IVDEP macros. (Thanks to Bernard Urban.)
7436 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
7437 with non-constant sizes. (Thanks to Bernard Urban.)
7439 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
7441 It's an "eval closure", not an "eval thunk." A thunk is a
7442 function of no arguments.
7443 * root.h (struct scm_root_state): Renamed
7444 top_level_lookup_closure_var from top_level_lookup_thunk_var.
7445 (scm_top_level_lookup_closure_var): Renamed from
7446 scm_top_level_lookup_thunk_var.
7447 * root.c (mark_root): Uses changed.
7448 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
7449 * init.c (scm_start_stack): Uses changed.
7450 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
7451 Change scheme-visible name to *top-level-lookup-closure* from
7452 *top-level-lookup-thunk*.
7454 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
7456 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
7457 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
7459 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
7461 * gc.c (struct scm_heap_seg_data): Doc fixes.
7463 * gc.c (scm_gc_sweep): Empty all segments' freelists before
7464 sweeping. Then, prepend each segment's free cells to its
7465 freelist, rather than wiping out the old value. (Thanks to Marius
7468 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
7469 scm_check_freelist, scm_debug_newcell): New functions and
7470 variables, for debugging freelist problems.
7471 * pairs.h (SCM_NEWCELL): New debugging version added.
7472 * gc.h (scm_debug_newcell): Added extern declaration, used by
7473 debugging version of SCM_NEWCELL.
7475 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7477 On some systems <libc.h> conflicts with <unistd.h>, and should not
7478 be #included at all.
7479 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
7480 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
7481 * configure.in: Call it.
7482 * posix.c, filesys.c: Use its results to decide whether or not to
7484 * configure, scmconfig.h.in: Rebuilt with autoconf and
7487 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7489 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
7490 pointer to the stdio stream before calling scm_setbuf0, so the
7491 latter will be able to retrieve it. I'm surprised this didn't
7492 segfault earlier. (Thanks to Christopher Lee.)
7494 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7496 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
7499 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7501 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
7502 number of stack narrowing specifier pairs. The first specifier in
7503 a pair controls inner border, the second the outer border. A
7504 number means cut that number of frames, a procedure object means
7505 cut until that object is found in operator position in a frame.
7507 * root.c (cwdr): Bugfix.
7509 * read.c: Recording of positions disabled by default.
7511 * procs.c (scm_closure_p): New function.
7513 * posix.c (scm_tmpnam): New function.
7515 * load.c: Added #include "throw.h".
7516 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
7519 * load.c, load.h (scm_read_and_eval_x): New function.
7521 * eval.c: Renamed debug option "deval" to "debug".
7523 (scm_eval_x): `eval!' is no longer accessible from the scheme
7524 level. Motivation: We can't allow operations which introduce
7525 glocs into the scheme level. Guile's type system can't handle
7526 these as data. Use `eval' or `read-and-eval!' as replacement.
7528 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
7529 SCM_CONSP since this is a macro!; Set vframe.prev to
7530 scm_last_debug_frame instead of 0. In this way we can look
7531 "above" the virtual start stack frame if we wish.
7532 (scm_debug_hang): New function: Useful for debugging Guile in
7533 certain tricky situations. Will probably be removed later...
7535 * debug.h: Changed semantics of debug option "backtrace". This
7536 option now only indicates whether we want automatic backtrace at
7539 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7541 * ports.c: #include "filesys.h"
7542 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
7544 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
7545 Motivation: This is system specific code which is related to file
7546 I/O. It also may use select. Added code by Gary Houston to
7547 detect presence of character in stdio buffers.
7549 * libguile.h: #include "libguile/libpath.h"
7551 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
7552 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
7553 SCM_SITE_DIR; Install libpath.h among the other include files.
7555 * load.c, load.h (scm_sys_package_data_dir): New function.
7557 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7559 * stacks.h: Bugfix: Don't use tail-array length field as stack
7560 length field! This screwed GC.
7562 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7564 * _scm.h: Added #ifndef around definition of macros min and max.
7566 * __scm.h: Added hooks for threads to plugin to in ints protection
7567 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
7568 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
7569 the main code in these macros duplicated and spread over multiple
7570 files. Renamed SCM_THREADS_SWITCHING_CODE ->
7571 SCM_THREAD_SWITCHING_CODE.
7573 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
7575 * snarf.h: New file.
7576 * guile-snarf.sh: New file.
7577 * Makefile.in (inner_h_files): Added snarf.h
7578 (ancillary, install, uninstall, distclean): Added actions for
7580 (.c.x): Use guile-snarf.
7581 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
7582 (gen_c_files): Note that these depend on guile-snarf.
7583 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
7584 now in "snarf.h". Added #include "snarf.h" to get them.
7585 * libguile.h: Added #include "snarf.h".
7586 (Patches applied and tweaked by Jim Blandy.)
7588 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7590 * socket.c: Use K&R style declaration for 'close'; the GNU coding
7591 standards suggest against providing prototypes for system
7592 functions. Thanks to Greg Troxel.
7594 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
7596 * strports.c (scm_eval_0str): New function.
7597 #include "read.h", to get prototype for scm_read.
7598 * Makefile.in (strports.o): Update dependencies.
7599 * strports.h: New prototype.
7601 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
7602 scheme name from "int?" to "integer?". It seems to do the job.
7603 * numbers.h: Rename prototype too.
7604 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
7607 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
7608 scm_num_eq_p): Rename these according to R4RS conventions: call
7609 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
7610 to making libguile R4RS compliant without ice-9...
7612 * load.c (scm_sys_search_load_path): Search for files under all
7613 extensions listed in the %load-extensions variable. If FILENAME
7614 is absolute, return it unchanged, without searching the load path.
7615 (scm_loc_load_extensions): New variable, pointing to
7616 %load-extensions' value cell.
7617 (scm_init_load): Initialize it, and the value it points to.
7618 (scm_primitive_load_path): Improve error reporting.
7620 * load.c (scm_loc_load_hook): New variable, pointing to value cell
7621 of new Scheme variable %load-hook.
7622 (scm_primitive_load): Apply %load-hook to filename.
7624 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
7626 * configure.in: add tests for figuring out whether buffered data
7627 is available in a FILE structure, which is needed by char-ready.
7629 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
7632 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
7633 exceptions using misc_error instead of syserror. It seems a bit
7634 odd to throw an exception if a string can't be found in the
7635 environment, but it's consistent with open-file, stat etc.
7636 (simpos.h): remove sys_ from getenv.
7638 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
7639 occurs, throw an error instead of returning errno. Return value
7641 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
7643 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
7645 * filesys.c (scm_stat2scm): derive file type and permissions from
7646 the stat mode and append them to the returned vector.
7647 There isn't much overhead in doing this and it avoids the need to
7648 work with S_IRUSR et al. in Scheme.
7649 Define symbols scm_sym_regular etc.
7650 (scm_init_filesys): don't intern S_IRUSR etc.
7652 * load.c: change s_try_load and s_try_load_path to s_primitive_load
7653 and s_primitive_load_path.
7655 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
7657 * error.h: don't declare error symbols. prototype for scm_misc_error.
7659 * stackchk.c (scm_stack_overflow_key): defined here instead of in
7662 * error.c: use SCM_SYMBOL to set up error keys.
7663 scm_misc_error: new procedure.
7665 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
7667 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
7668 between `#!' and `!#' is ignored.
7669 (skip_scsh_block_comment): New function.
7671 * feature.c (scm_set_program_arguments): New argument, FIRST.
7672 * feature.h: Update prototype.
7673 * init.c (scm_boot_guile_1): Pass new argument to
7674 scm_set_program_arguments.
7676 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
7678 * init.c (scm_start_stack): Don't initialize scm_progargs here.
7679 (scm_boot_guile): Call scm_set_program_arguments here, later than
7680 the old initialization.
7682 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
7683 initialization procedure.
7684 - Delete in, out, err arguments; there are other perfectly good
7685 ways to override these when desired.
7686 - Delete result argument; this function shouldn't ever return.
7687 - Rename init_func argument to main_func, for less confusion.
7688 - Delete boot_cmd argument; main_func is more general.
7689 -Add 'closure' argument, to help people pass data to main_func
7690 without resorting to global variables.
7691 - Abort if reentered; don't bother returning an error code.
7692 - Call scm_init_standard_ports to set up the default/current
7693 standard ports; no need to pass them to scm_start_stack.
7694 - Remove code to evaluate the boot_cmd, and start the repl; let
7695 the user do something like that in main_func if they want.
7696 - Remove code to package up a return value; main_func can do any
7698 - Call exit (0), instead of returning.
7699 (scm_start_stack): Don't initialize the I/O ports here; that's
7700 weird. Delete in, out, err arguments. Move guts to
7701 scm_init_standard_ports, scm_stdio_to_port.
7702 (scm_init_standard_ports): New function, to set up current and
7703 default standard ports.
7704 (scm_start_stack, scm_restart_stack): Make these static.
7705 * init.h (scm_boot_guile): Adjust declaration.
7706 (scm_start_stack, scm_restart_stack): Remove externally
7707 visible declarations for these.
7708 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
7710 * fports.c (scm_stdio_to_port): New function. Its guts used to be
7711 written out several times in scm_start_stack.
7712 * fports.h: New declaration for the above.
7714 * feature.c (scm_set_program_arguments): New function.
7715 * feature.h: New declaration for the above.
7717 * ports.c: Formatting tweak.
7719 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
7721 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
7722 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
7723 for obtaining the address of a car or cdr field. Motivation:
7724 &SCM_CXR make assumptions about the internal structure of the
7727 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
7728 Motivation: see SCM_CXRLOC.
7730 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
7731 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
7732 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
7733 Motivation: Safer use. Some other macros are defined in terms of
7734 these operations. If these are defined using the SCM_SETCXR
7735 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
7736 to inefficiency and an <e1> with side-effects could potentially
7737 break. Also, these particular operations are heavily utilized in
7738 the garbage collector. In unoptimized code there will be a
7741 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
7742 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
7743 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
7744 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
7745 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
7746 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
7747 vports.c: Cleaned up use of pairs: Don't make any special
7748 assumptions about the internal structure of selectors and
7749 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
7750 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
7751 (Among other things, this change makes it easier to build Guile
7752 with certain compilers which have problems with casted lvalues.)
7754 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7756 * stacks.c: Improve selection of relevant stack frames when making
7757 a stack object. Introduce one level of indirection in the stack
7758 object to make it possible to "narrow" to a certain region of the
7759 stack. This facilitates making use of more clever algorithms (not
7760 implemented) for selecting relevant frames and gives a cleaner
7761 design since selection of frames can be done independently of
7762 extraction of frames from the real stack.
7763 (scm_stack_id): Also take #t as argument which means look at
7766 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
7767 Turn n_tail into an integer directly representing current number
7768 of frames in stack. Add field tail.
7770 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
7772 * debug.c (scm_make_memoized): Made it available at scheme level.
7773 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
7774 SCM_NIMP before applying heavier predicates in argument checking.
7775 (scm_local_eval): Also take memoized object as argument.
7777 * backtrace.c (scm_display_error): Just a safety measure: Stacks
7778 aren't created with zero length, but should such a strange
7779 creature suddenly turn up...
7781 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
7783 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
7784 `del', for the sake of C++ compilers. (Patch applied by JimB.)
7786 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
7788 * variable.c (scm_make_variable): Make the name hint optional, as
7790 (anonymous_variable_sym): Renamed from variable_sym. All uses
7793 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
7794 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
7795 of scm_primitive_load_path was also changed to
7796 "primitive-load-path", from "%try-load-path". Callers changed.
7797 We'd like to respect the convention that a function named
7798 "try-mumble" should behave just like the function called "mumble",
7799 but return #f instead of signalling some error.
7800 * load.h: Rename prototypes.
7802 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7804 * print.c (make_print_state, grow_print_state), print.h: Modified
7805 the print state representation: Don't use a tail array for
7806 recording of circular references. Resizing of the print state
7807 structure invalidates the print state pointer. To avoid passing
7808 around an indirect print state reference to all printing
7809 functions, we instead let the print state reference a resizable
7812 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7814 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
7815 Don't crash when passed an improper list terminated by a
7816 non-immediate value.
7818 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
7820 Allocate data for structures on an eight-byte boundary, as
7821 required by the tagging system.
7822 * struct.c (alloc_struct): New function.
7823 (scm_make_struct, scm_make_vtable_vtable): Call it.
7824 * struct.h (scm_struct_n_extra_words): Bump to 3.
7825 (scm_struct_i_ptr): New "field".
7826 * gc.c (scm_gc_sweep): When we need to free the data, use the
7827 information stored by alloc_struct to find the beginning of the
7828 block allocated to the structure, so we can free it.
7830 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7832 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
7835 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
7836 (scm_debug_info): New member: id.
7838 * stacks.c: Stacks are now represented as structs; Stacks have an
7839 id given to them by `start-stack'.
7840 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
7842 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
7843 Changed stack representation.
7845 * debug.c (scm_procedure_name): Try procedure property `name' for
7846 compiled closures aswell.
7848 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
7850 * eval.c: scm_i_name moved to gsubr.c
7851 (scm_m_define): Record names of all kinds of procedure
7852 objects. (Earlier, only closures were recorded.)
7854 * procprop.h: Added declaration of scm_i_name.
7856 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
7857 (scm_make_gsubr): Record names of compiled closures.
7859 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7861 * debug.c, debug.h: Removed obsolete code.
7863 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
7864 stacks.c: Renamed regs --> scm_contregs.
7866 * print.c (scm_free_print_state): Cleanup print state before
7867 returning it to pool. It is better to do it here than in
7868 scm_prin1 since scm_prin1 is called often.
7870 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
7871 s_set_source_property_x): Check that first argument is a pair or a
7874 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
7875 scm_i_line, scm_i_column and scm_i_breakpoint global.
7877 * init.c: Added #include "backtrace.h" and #include "stacks.h".
7878 (scm_boot_guile_1): Added calls to scm_init_backtrace and
7881 * debug.h: Added debug object smob declaration and macro
7884 * configure.in: Build with backtrace.o and stacks.o if debug
7887 * Makefile.in: Added entries for new files: backtrace.c,
7888 backtrace.h, stacks.c and stacks.h.
7890 * symbols.c (scm_sym2ovcell): Fixed documentation.
7892 * _scm.h (min, max): Added.
7894 * async.c: Moved `min' macro to _scm.h.
7896 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
7897 SCM_BACKTRACE_INDENT.
7899 * eval.c: Added new debug options `maxdepth' and `indent'.
7901 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
7903 * print.h: Added selector SCM_PRINT_STATE.
7905 * print.c: New functions: scm_make_print_state,
7906 scm_free_print_state.
7908 * print.h: Added declarations for scm_make_print_state,
7909 scm_free_print_state.
7911 * debug.c (scm_m_start_stack): New acro.
7913 * debug.h: Small cleanup.
7915 * init.c (scm_boot_guile_1): Moved scm_init_debug below

7938 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
7939 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
7940 declare functions with prototypes. (Patch thanks to Marius
7943 More prototype-related changes from Marius Vollmer:
7944 * gdb_interface.h: Wrapped header file in #ifdef/#endif
7945 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
7946 * ports.h (ptobfuns): Added prototypes. This means some casting in
7948 * fports.c: Added casts for initializations, since the functions
7949 are defined to take FILE * as their stream argument, not SCM.
7950 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
7951 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
7952 to `char *str_data' to conform to prototype.
7954 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7956 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
7958 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
7960 * stime.c, stime.h: use SCM_P method.
7962 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7964 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
7965 be given at least two arguments. Insist that lst's last element
7966 be a list, but don't make any requirements of its predecessors.
7968 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7970 * eval.c (scm_nconc2last): Revert last change; there seems to be
7971 other stuff going on here.
7973 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7975 * eval.c (scm_nconc2last): Make sure that each element of lst
7976 (which is a list of argument lists, except for the tail) is a
7977 proper list, i.e., finite and terminated by '().
7979 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7981 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7984 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7985 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7988 * vectors.c (scm_make_vector): Fill vectors with the undefined
7989 value, to help make Guile Scheme code more portable to other
7992 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7993 * symbols.h, tags.h: Doc fixes.
7995 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
7997 * async.c (scm_take_signal): Doc fixes.
7999 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
8001 * numbers.c (scm_divbigint): When the remainder is zero, we don't
8002 want to subtract it from the modulus; we just want to leave it
8005 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
8007 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
8010 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
8012 * throw.c (scm_catch_apply): Finished implementation of
8015 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
8017 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
8019 (scm_init_filesys): set "i/o-extensions" feature.
8022 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
8024 * Makefile.in (root.o): Correct dependencies.
8026 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
8028 * Makefile.in: Added dependency entry for root.o.
8030 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
8031 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
8033 * init.c (scm_start_stack): Set initial root continuation number
8036 * procs.c: New function: scm_thunk_p.
8038 * procs.h: Added declarations of scm_thunk_p.
8040 * root.c: Renamed `call-with-new-root' -->
8041 `call-with-dynamic-root'.
8042 (cwdr): Removed allocation of new root state. This should be done
8043 separately by use of scm_make_root.
8044 (scm_apply_with_dynamic_root): New function: Does what it
8045 sounds like. Needed when spawning threads.
8047 * root.h: Added member last_debug_frame to root state.
8048 Added #include "libguile/debug.h"
8050 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
8051 arguments. The motivation is that code in root.c needs catch
8052 functionality, and we want to avoid code duplication.
8053 New functions: scm_catch, scm_lazy_catch. These are wrappers for
8054 scm_catch_apply. scm_lazy_catch is intended to introduce catch
8055 handlers that run without popping the stack into the dynwind
8058 * throw.h: Added prototypes for scm_catch_apply and
8061 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8063 * root.h (scm_root, scm_set_root): Decouple thread support details
8064 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
8065 SCM_SET_THREAD_LOCAL_DATA.
8067 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
8068 and tortoise scanning loop.
8070 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
8072 * Makefile.in: Rebuild dependencies.
8074 * libguile.h: #include "libguile/print.h" before "smob.h", since
8075 the latter uses the print_state structure.
8077 * throw.c (scm_ithrow): Use the correct variable when checking to
8078 see if a given element of scm_dynwinds is a valid catch.
8080 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
8081 structure, abort; don't just silently ignore the garbage.
8083 * _scm.h: #include "print.h" here, since it seems to be used just
8085 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
8086 strports.c, unif.h: Don't #include "print.h".
8088 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8090 * feature.h (scm_loc_features): Removed external declaration.
8091 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
8093 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8095 * feature.c (scm_init_feature): Added threads feature (needs to be
8096 initialized here, since features doesn't exist when
8097 scm_init_threads is called).
8099 * libguile.h: Added #include "libguile/../threads/threads.h".
8100 (This is a kludge to get thread support working. This should be
8103 * configure.in, acconfig.h: Added flags for thread support.
8105 * scmsigs.c: Define `signal' to be `pthread_signal' if using
8108 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
8109 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
8112 * _scm.h: Added conditional #include "threads.h"
8114 * __scm.h (SCM_ASYNC_TICK): Added call to macro
8115 SCM_THREADS_SWITCHING_CODE.
8117 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
8118 allocate the basic dynamic root object.
8119 (scm_boot_guile): Added call to scm_init_root.
8121 * root.c, root.h: Added root smob.
8122 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
8123 functions: Implements dynamic roots mostly according to spec in
8124 SCM manual. Main difference is that the second argument is a
8125 throw handler rather than an error "thunk".
8127 * root.h: Added declaration of scm_init_root.
8129 * root.c: Added #include "genio.h", #include "smob.h", #include
8130 "pairs.h", #include "throw.h", #include "dynwind.h", #include
8132 (scm_init_root): Added #include "root.x".
8134 * throw.c: Added #include "stackchk.h"
8135 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
8136 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
8137 can be used in scm_call_with_new_root; Added reenabling of stack
8138 checking when catching a throw.
8140 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
8142 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
8144 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
8145 element is not found, as per R4RS.
8147 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
8149 * list.c: Doc fixes throughout.
8151 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
8153 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
8154 declare the char * to be const. Avoids a warning in rgx.c.
8156 * ports.h: spelling fix.
8158 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
8161 * load.c (scm_sys_try_load_path): throw an error if file not found
8162 (like it says it in NEWS).
8164 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
8166 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
8167 PROPS slot to '(), not #f; it's an empty alist.
8169 * throw.h, throw.c: Use SCM_P instead of #if hair.
8171 Remove special support for uncaught throws; see throw.c for
8173 * throw.c (uncaught_throw): New function.
8174 (scm_ithrow): Call uncaught_throw if we don't find a throw
8175 target; don't mess with scm_bad_throw_vcell.
8176 (scm_bad_throw_vcell): Variable deleted.
8177 (scm_init_throw): Don't initialize it.
8179 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
8182 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
8184 * numbers.c (scm_istr2int): If the number is short (as most
8185 numbers are), just call scm_small_istr2int to deal with it.
8186 (scm_small_istr2int): New function, created by un-#ifdefing the
8187 non-bignum version of scm_istr2int and renaming it.
8189 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
8191 * load.c (scm_sys_try_load): don't check whether value returned
8192 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
8193 Change the Scheme name from %try-load to primitive-load.
8195 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
8196 Can avoid passing a message, allowing it to be derived in the
8197 error handler (e.g., if we want to throw to the key both from
8200 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
8202 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
8203 references now have a new appearance which is more compact and
8204 also gives a clue about what the target of the reference is.
8205 By setting parameters in the print state, more fancy printing can
8206 be achieved. This is used by the (not yet commited) backtrace
8209 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
8211 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
8214 * print.c: Added #include "struct.h". Removed function
8217 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
8218 scm_iprin1. Removed prototype for scm_prlist.
8220 * arbiters.c (prinarb),
8221 async.c (print_async),
8222 debug.c (prindebugobj, prinmemoized),
8223 eval.c (prinprom, prinmacro),
8224 filesys.c (scm_fd_print, scm_dir_print),
8226 mallocs.c (prinmalloc),
8227 numbers.c, numbers.h (scm_floprint, scm_bigprint),
8228 smob.h (scm_smobfuns),
8229 srcprop.c (prinsrcprops),
8231 unif.c, unif.h (scm_raprin1, rapr1),
8232 variable.c (prin_var): Changed argument `int writing' to
8233 `scm_print_state *pstate'.
8235 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
8236 that it will be called before scm_init_print.
8238 * print.c (scm_prin1): Print states are now allocated when calling
8239 scm_prin1 and then passed around to all printing functions as an
8240 argument. A cache `print_state_pool' enables reuse of print
8242 (scm_make_print_state): New function.
8243 (scm_iprin1): Adaption to print states.
8244 (scm_iprlist): An initial "hare and tortoise" scan brings down
8245 time complexity to O (depth * N). (Better time complexity will be
8246 achieved when the printing code is completely rewritten.)
8248 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
8250 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
8251 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
8252 it gets done whether or not the cache variable has a value.
8254 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8256 Distinguish #f and ().
8257 * __scm.h: #undef SICP.
8258 * pairs.h (SCM_EOL): Delete this definition, equating it with
8260 * tags.h (SCM_EOL): Give it a new definition here; I think I found
8261 the value it used to have. Doc fixes, too.
8263 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
8265 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
8266 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
8267 Lord's implementation of structs, allowing for tail arrays as
8268 described in the manual. Also fixed some bugs. (Both the interface
8269 and the implementation should be improved.)
8271 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
8273 * print.c, print.h: Closures now print like #<procedure foo (x)>.
8274 People who whish to see the source can do `(print-enable 'source)'.
8275 Removed #ifdef DEBUG_EXTENSIONS.
8277 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
8279 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
8280 integer (assuming for now accepting an integer is a good thing).
8282 * error.c, fports.c: replace use of %S in lgh_error args with %s.
8283 %S will be used instead for write'ing arguments.
8285 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
8286 asserts. fix a few other asserts.
8287 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
8288 scm_uniform_vector_ref, scm_array_set_x,
8289 scm_dimensions_to_unform_array): change args in
8290 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
8291 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
8292 scm_substring_fill_x): likewise.
8293 gsubr.c (scm_gsubr_apply): likewise.
8294 eval.c (SCM_APPLY): likewise.
8296 * eval.c (4 places): replace scm_everr with lgh_error or
8299 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
8300 scm_memory_error): new procedures.
8301 scm_everr: deleted. can use scm_wta, dropping first two args.
8302 scm_error: convert NULL subr to SCM_BOOL_F.
8304 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
8307 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
8310 * error.c, error.h: new error keys: scm_arg_type_key,
8311 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
8313 scm_wta: reimplement using lgh_error instead of scm_everr.
8315 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
8317 * gdbint.c: scm_lread now has one more argument.
8319 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
8320 scm_port_\1; Added mutator scm_set_port_filename_x (used when
8321 loading source from non-file ports, which, e. g., happens when
8322 using the Emacs interface).
8324 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
8327 * read.c: Added code for recording of positions of source code
8328 expressions; New functions: recsexpr, scm_lreadrecparen;
8329 _scm_make_srcprops --> scm_make_srcprops
8330 (scm_flush_ws): Removed updating of positions counters. This work
8331 is already done by scm_gen_getc
8333 * read.h: Added prototype for scm_lreadrecparen
8335 * print.c: Added #include "alist.h"
8337 * eval.c: Added #include "hash.h"
8339 * eq.c: Added #include "ramap.h"
8341 * options.c: Documentation fixes.
8343 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
8344 (scm_init_srcprop): Adjusted size of initial source-whash. Name
8345 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
8346 --> scm_make_srcprops
8348 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
8349 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
8350 function calls in the definition of the whash access macros.
8352 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
8354 * init.c (scm_boot_guile): Add level of indirection to
8355 scm_boot_guile_1() to ensure that stack base pointer is properly
8356 initialized. There was no guarantee that variable i was the
8357 highest/lowest variable on stack (i.e. the call frame of
8358 scm_boot_guile was not completely protected from gc).
8360 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
8362 * ports.h (scm_port_table): put back file_name, it will be used to
8363 support debugging. Undo related changes in fports.c, ioext.c,
8366 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
8368 * ports.h (scm_port_table): remove file_name member for now, it seems
8370 * fports.c (scm_open_file): don't set file_name in PTAB.
8371 (prinfport): don't use file_name in PTAB.
8372 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
8373 * ports.c (scm_add_to_port_table): don't intialize file_name.
8374 (scm_port_file_name): remove for now.
8375 * gc.c (scm_gc_mark): don't mark PTAB file_name.
8377 * fports.h (scm_mkfile): prototype deleted.
8378 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
8380 * debug.c, unif.c: use scm_out_of_range instead of
8381 wta for range errors (ASSERT still needs work).
8383 * error.c, error.h (scm_out_of_range): new procedure.
8385 * error.c, error.h (scm_out_of_range_key): new key.
8387 * posix.c (scm_sync): #else was missing.
8389 * error.c, error.h: append _key to names scm_num_overflow and
8392 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
8393 of consing an empty list.
8394 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
8395 of macros, saves code and string space.
8396 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
8397 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
8398 lower case. Rename scm_syserror_m to scm_syserror_msg.
8399 error.h: prototypes for new procedures.
8401 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
8403 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
8405 * error.c, error.h: setup scm_num_overflow key.
8407 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
8408 Remove definition of SCM_OVSCM_FLOW.
8410 * fports.c (scm_open_file): use SCM_SYSERROR_M.
8412 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
8413 explicit message and args.
8415 * error.c, error.h, __scm.h: change system_error_sym to
8418 * error.c (system_error_sym): remove leading %% from the Scheme name
8421 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
8423 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8425 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
8426 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
8427 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
8428 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
8429 renamed. (These were introduced by unsupervised name
8432 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8434 * print.c: Added code for detection of circular references during
8435 printing. (init_ref_stack, grow_ref_stack): New functions. Added
8436 a hook for printing of closures (accessible via print options).
8437 This leads to a split of calls to scm_iprin1 into two classes:
8438 elementary print operations (e. g. the code which prints a smob)
8439 still use scm_iprin1 while top level calls (like scm_display) use
8440 scm_prin1. scm_prin1 begins by clearing the data structure used
8441 to record reference information.
8443 * print.h: Added declarations of scm_prin1 and scm_prlist.
8445 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
8447 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
8449 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
8451 * error.c (err_head): scm_iprin1 --> scm_prin1
8453 * debug.c: Adjusted header comment.
8457 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
8459 * strerror.c: Doc fix.
8461 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8463 * gdbint.c (gdb_read): Now possible to run during GC.
8464 (unmark_port, remark_port): New functions.
8466 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
8468 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
8469 of allocating a new string object. Also, increase size by
8470 the factor 2 instead of 1.5.
8472 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
8474 * __scm.h (SCM_P): Corrected to run under traditional C.
8476 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
8479 * async.c: Calls to scm_sysintern corrected.
8481 * async.h (scm_async_clock): Redundant declaration removed.
8483 * continuations.c (scm_dynthrow): Redundant declaration removed.
8485 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
8486 Definition typos corrected.
8488 * debug.h: Missing declarations of functions in debug.c added
8491 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
8492 Missing declarations to functions in eval.c added.
8494 * filesys.c: Possibly uninitialized variable rv.
8496 * gc.h (scm_object_addr, scm_unhash_name): Missing
8497 declarations of functions defined in gc.c added.
8499 * genio.c: Possible typos str_data -> wstr_data. ???
8501 * genio.c: Possibly unintended shadowing of local variable
8502 `int c' (gotos out of scope of inner `c'). ???
8504 * init.c: Uninitialized `SCM last' may be used.
8506 * ioext.h: (scm_sys_isatty_p): Typo.
8508 * list.h (scm_list_head): Missing prototype for function in
8511 * numbers.c (scm_two_doubles): Changed from extern to static
8512 (is used only within numbers.c).
8514 * numbers.h: Repeated declarations removed.
8516 * ports.h (scm_close_all_ports_except): Declaration for the
8517 function defined in ports.c added.
8519 * posix.h: Missing declarations added.
8521 * procs.h (scm_make_subr_opt): Missing declaration added.
8523 * socket.h (scm_sys_gethost): Missing declaration added.
8525 * socket.h: Redundant declarations removed (they are in fdsocket.h).
8527 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
8528 Missing declarations added.
8530 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
8532 * struct.c: Uninitialized variable `SCM answer' may be used.
8534 * unif.c (l2ra): Declaration prototype.
8536 * unif.c (scm_array_equal_p): Dummy definition removed (it is
8537 defined in ramap.c).
8539 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
8540 Redundant declarations removed (they are in ramap.h).
8542 * variable.h (scm_make_udvariable,
8543 scm_make_undefined_variable): Declaration corrected to
8544 correspond variable.c.
8546 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
8547 Missing declarations added.
8549 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
8551 * Makefile.in (distclean): Don't forget to delete fd.h.
8553 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
8555 * fd.h.in, tags.h: Trivial cleanups.
8557 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
8558 marksweep.h just declared functions from gc.c.
8559 * gc.h, libguile.h: Don't #include "marksweep.h".
8560 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
8561 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
8562 dependencies updated.
8564 * libguile.h: Don't #include "files.h"; it's been deleted.
8566 * files.c (scm_sys_delete_file): Moved to filesys.c.
8567 File is now empty; deleted.
8569 * filesys.c: scm_sys_delete_file is now here. Remove
8570 #if's; they seem to rely on remnants of an old portability
8571 regimen. If the problems come up again, solve them properly,
8572 using autoconf. Specifically: Don't test M_SYSV, and #define
8573 remove to be unlink if it's #defined; don't use remove just
8574 because HAVE_STDC_HEADERS is #defined.
8575 * filesys.h: Add declarations for scm_sys_delete_file.
8576 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
8577 files.o, files.h, files.c, and files.x.
8578 * init.c: Don't #include "files.h", and don't call scm_init_files.
8580 Use SCM_P instead of PROTO; the latter intrudes on the user's
8582 * params.h: Deleted; definition of SCM_P moved to...
8583 * __scm.h: ... here, where it replaces PROTO macro.
8584 * libguile.h, smob.h: Don't #include "params.h".
8585 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
8586 smob.h: Fix prototypes accordingly.
8587 * Makefile.in: Update dependencies.
8588 (inner_h_files): Remove params.h.
8590 * gc.c: #include "gc.h"; every module should include its header,
8591 to let the compiler cross-check the declarations against the
8594 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
8595 simpos.h: #include "libguile/__scm.h".
8597 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
8599 * init.c: Don't forget to #include smob.h and init.h.
8600 * Makefile.in: Dependencies updated.
8602 * smob.h: Use PROTO instead of #if __STDC__.
8604 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
8606 * __scm.h: Doc fixes.
8608 * __scm.h, libguile.h: Use "quotes" in the #includes, not
8609 <angles>; this allows `make depends' to work properly.
8611 * libguile.h: #include smob.h and pairs.h before the others; they
8612 define typedefs used by other headers.
8614 C files should #include only the header files they need, not
8615 libguile.h (which #includes all the header files); the pointless
8616 recompilation was wasting my time.
8617 * Makefile.in (all .o dependency lists): Regenerated.
8618 * libguile.h: Don't try to get a definition for size_t here...
8619 * __scm.h: Do it here.
8620 * _scm.h: Since this is the internal libguile header, put things
8621 here that all (or a majority) of the libguile files will want.
8622 Don't #include <libguile.h> here; that generates dependencies on
8623 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
8624 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
8625 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

8724 * stackchk.h: #include "libguile/debug.h",
8726 * print.h, read.h: #include "options.h", since everyone who uses
8727 either of these files will need that.
8729 * smob.h: #include "ports.h", "genio.h", and "print.h", since
8730 anyone who uses this file will need them to define the smob
8731 printing functions. Also, get markers.h, since people will need
8732 to #define the mark functions.
8734 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
8735 * ports.h: ... to here.
8737 * ports.h (scm_port_table_size): Explicitly give type as 'int';
8738 don't rely on archaic C default type rules.
8740 * fports.h: #include "libguile/ports.h", since you need that in
8741 order to parse this.
8743 * genio.h: #include "libguile/print.h", because you need that to
8744 parse this; don't bother #including "ports.h", since print.h gets
8747 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
8749 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
8750 this; it's now a reference to an element of *scm_root.
8752 * debug.h: Don't #include "options.h"; the compiler won't be able
8753 to find that once the headers are installed; instead, #include
8754 "libguile/options.h".
8755 * gc.h: Same, with marksweep.h.

8757 * scmhob.h: Same, with _scm.h.
8758 * smob.h: Same, with params.h.
8760 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
8761 C files; there's no need for this, and it forces recompilations
8764 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
8766 * error.c (scm_error): declare scm_error_callback.
8768 * error.h: prototype for scm_error_callback.
8770 * __scm.h: define lgh_error.
8771 (SCM_SYSERROR): redefine using lgh_error.
8773 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
8775 * error.c (scm_error): new procedure.

8779 * Makefile.in (install): install scmconfig.h from the current

8797 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8799 * Makefile.in (.c.x): Simplify; there's no need to run this rule
8800 when scmconfig.h doesn't exist.
8802 * load.c (scm_sys_try_load): Correct spelling.
8804 * feature.c (scm_loc_features): Make this static.
8806 * Makefile.in (libpath.h): Omit trailing slash from path. We
8807 shouldn't require it of users, so why put it here?
8809 Move code to initialize and search %load-path from ice-9 to C
8810 code, so we can use the load-path to find the ice-9 boot code;
8811 this makes it easier to run Guile without installing it. See
8812 corresponding changes in guile/Makefile.in.
8813 * feature.c: Move stuff concerned with the load path to load.c.
8814 (scm_compiled_library_path): Deleted.
8815 Don't #include libpath.h here.
8816 * feature.h: Don't mention scm_compiled_library_path.
8817 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
8818 <sys/stat.h>, and <unistd.h> (if present).
8819 (R_OK): #define if the system hasn't deigned to.
8820 (scm_loc_load_path): New variable.
8821 (scm_init_load_path, scm_sys_search_load_path,
8822 scm_sys_try_load_path): New functions.
8823 (scm_init_load): Initialize scm_loc_load_path to point to the
8824 value cell of the Scheme %load-path variable.
8825 * load.h: Add declarations for scm_sys_search_load_path,
8826 scm_sys_try_load_path.
8827 * init.c: Call scm_init_load_path.
8828 * Makefile.in (feature.o, load.o): Dependencies updated.
8830 * load.c, load.h: Rewrite using PROTO macro.
8832 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8834 * gc.c (scm_cellp): New function: C predicate to determine if an
8835 SCM value can be regarded as a pointer to a cell on the heap.
8837 * gc.h: Added declaration of scm_cellp.
8839 * gdb_interface.h: New file: The GDB interface header from the GDB
8842 * gdbint.c: New file: GDB interface.
8844 * gdbint.h: New file: GDB interface.
8846 * libguile.h: Added #include <libguile/gdbint.h>.
8848 * init.c (scm_boot_guile): Added scm_init_gdbint.
8850 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
8851 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
8852 found if object files and source are kept separate).
8854 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
8856 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
8858 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
8860 * configure.in: Don't substitute the values of TCL_SRC_DIR and
8861 TK_SRC_DIR; they're not relevant any more.
8863 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
8864 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
8866 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
8868 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
8869 search path, so we can find the <libguile/MUMBLE.h> headers.
8871 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
8873 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
8874 implicit in the .c.o rule.
8875 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
8878 Put the library path in a header file, instead of passing it on
8879 the command line in every compilation.
8880 * Makefile.in (libpath.h): New target.
8881 (feature.o): Depend on libpath.h.
8882 (clean): Delete libpath.h.
8883 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
8884 * feature.c: ... #include "libpath.h" here.
8885 * .cvsignore: Ignore libpath.h.
8887 Don't install the unwashed masses of Guile header files in the
8888 main #include path; put most of them in a subdirectory called
8889 'libguile'. This avoids naming conflicts between Guile header
8890 files and system header files (of which there were a few).
8891 * Makefile.in (pkgincludedir): Deleted.
8892 (innerincludedir): New variable; this and $(includedir) are enough.
8893 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
8894 (installed_h_files): Divide this up. Now this variable lists
8895 those header files which should go into $(includedir) (i.e. appear
8896 directly in the #include path), and ...
8897 (inner_h_files): ... this new variable says which files appear in
8898 a subdirectory, and are referred to as <libguile/mumble.h>.
8899 (h_files): List them both.
8900 (install): Create innerincludedir, not pkgincludedir. Put
8901 the installed_h_files and inner_h_files in their proper places.
8902 (uninstall): Corresponding changes.
8903 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8904 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8905 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
8906 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
8907 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
8908 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8909 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8910 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8911 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8912 vports.h, weaks.h: Find __scm.h in its new location.
8913 * __scm.h: Find scmconfig.h and tags.h in their new locations
8914 (they're both "inner" files).
8916 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
8918 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
8920 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
8922 * posix.c: Doc fixes.
8924 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
8926 * socket.c: Don't include a prototype for inet_aton; just use a
8927 K&R style declaration, to avoid warnings but minimize the chance
8928 of conflicts with the system.
8930 On NextStep, <utime.h> doesn't define struct utime, unless we
8931 #define _POSIX_SOURCE before #including it.
8932 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
8933 * acconfig.h: New comment text for above CPP symbol.
8934 * configure.in: Call it.
8935 * posix.c: #define _POSIX_SOURCE if it seems necessary.
8937 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
8939 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
8940 testing for __EMX__.
8942 * posix.c: #include <libc.h>, if it exists.
8944 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
8945 don't even know if the latter exists.
8947 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
8948 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
8949 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
8951 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
8953 (scm_init_posix): Use them when initializing the Scheme constants
8956 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
8958 * Makefile.in (libdir, includedir, bindir): Use the
8959 autoconf-supplied values, instead of deriving them ourselves.
8960 (pkgincludedir, datadir, pkgdatadir): New variables.
8961 (install, uninstall): Put the header files in a special
8962 subdirectory, not in the main search path.
8964 * Makefile.in (ALL_CFLAGS): Provide the proper value for
8965 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
8967 * Makefile.in (IMPLPATH): Deleted; never used.
8969 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
8970 on the Tcl/Tk source any more.
8971 (INCLUDE_CFLAGS): Remove references to the above.
8973 * Makefile.in (version.o): Corrected dependencies.
8975 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8977 * libguile.h: #include "version.h"
8979 * init.c (scm_boot_guile): Call scm_init_version.
8980 * gscm.c (gscm_run_scm): Call scm_init_version.
8982 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8983 GUILE_VERSION): AC_DEFINE these.
8984 (acconfig.h): #undef the above symbols.
8986 * Makefile.in (libobjs): Add version.o.
8987 (installed_h_files): Add version.h.
8988 (c_files): Add version.c.
8989 (gen_c_files): Add version.x.
8990 (version.o): New rule.
8991 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
8992 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
8993 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
8994 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
8995 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
8996 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
8997 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
8998 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
8999 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
9000 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
9001 weaks.o): Add version.h to dependency lists.
9002 (markers.o): Remove duplicate rule.
9004 * version.h: New file.
9006 * version.c: New file.
9008 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
9010 * symbols.c (scm_strhash): scm_downcase is now a function, not an
9011 array; use it appropriately. Since GCC is quite happy to
9012 subscript functions, it never warned us about this; we should use
9013 -Wpointer-arith in the future. I guess we never tested
9016 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
9018 * socket.c: Doc and copyright fixes.
9020 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
9022 * debug.c: Fixed and improved gdb support.
9024 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
9026 * socket.c: Added declaration of inet_aton to avoid compiler
9027 warning. (Hope this solution is correct.)
9029 * stime.c: Added declaration of ftime. (This is missing in
9032 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
9034 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
9036 * Makefile.in (c_files): add strerror.c.
9038 * strerror.c: new file from Emacs' sysdep.c.
9039 maybe configure should also check for sys_errlist.
9041 * configure.in (AC_REPLACE_FUNCS): add strerror.
9043 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
9045 * debug.c (scm_init_debug): Added initialization for
9046 scm_evaluator_traps.
9048 * debug.h, debug.c: Various name changes.
9049 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
9050 "debug-options-interface". See commentary in options.c.
9052 * options.h, options.c: Options now have documentation strings.
9053 Also added a long explanatory commentary.
9055 * eval.c, print.h, print.c, read.h, read.c: Modifications to
9058 * gscm.c, init.c, root.c, throw.c: Bug fixes:
9059 last_debug_info_frame is now updated in all cases.
9061 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
9064 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
9066 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
9067 Added option STACK_CHECKING.
9069 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
9071 * Makefile.in: Added {debug,options,srcprop}.{h,c}
9073 * __scm.h: Removed symbols for debugging support.
9075 * acconfig.h: Added symbols for debugging support.
9077 * configure.in: Added user option for debugging support.
9078 --enable-debug will include the debugging code into libguile.a.
9080 * continuations.c (scm_make_cont): Enlarged the #if 0 around
9081 scm_relocate_chunk_to_heap.
9083 * debug.c: New file: low-level debugging support. It also
9084 includes support for debugging with gdb. (The extensions to gdb
9085 are written by Per Bothner at Cygnus.)
9087 * debug.h: New file: low-level debugging support.
9089 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
9090 argument pairs. Extensive modifications to the debugging
9091 evaluator. Added "SECTION:" commentaries to clarify what happens
9092 when, during double compilation. Renamed EVALIMP --> EVALIM.
9093 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
9094 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
9095 the beginning of the file. New procedure: scm_unmemocopy.
9096 Added some global state variables needed by the debugging
9097 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
9098 check_entry, check_apply, check_exit, debug_options and
9099 evaluator_traps. New acro: undefine.
9101 * eval.h: Renamed EVAL --> XEVAL.
9103 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
9104 --> scm_make_weak_key_hash_table.
9106 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
9107 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
9109 * libguile.h: Conditionally include debug.h
9111 * objprop.c (scm_object_properties, scm_set_object_properties_x):
9112 scm_object_properties shouldn't return handle. `handle' now gets
9113 initialized in scm_set_object_properties_x. scm_object_properties
9114 doesn't any longer create an entry in scm_object_whash.
9116 * options.c: New file: handling of run time options.
9118 * options.h: New file: handling of run time options.
9120 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
9122 * print.c: New procedure: scm_print_options
9124 * print.h: Defines for print options.
9126 * read.c: New procedure: scm_read_options
9128 * read.h: Defines for reader options.
9130 * root.h: Added scm_source_whash among scm_sys_protects.
9132 * srcprop.c: New file: source properties.
9134 * srcprop.h: New file: source properties.
9136 * throw.c (jbsmob): Jump buffers are now correctly allocated.
9137 (Bug found by A. Green.)
9139 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
9141 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
9143 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
9145 * libguile.h: #include "objprop.h"; I guess this was forgotten.
9147 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
9148 and should be called by the final client.
9150 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
9152 * gc.h: Use the PROTO macro when declaring functions.
9153 * gc.c: Use the PROTO macro when declaring static functions.
9154 Remove the CPP hair around function definitions.
9156 * gc.c (scm_init_storage): Initialize scm_asyncs.
9158 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
9159 preprocessor symbol; "__scm.h" is where it might get #defined.
9160 * __scm.h: Similar: #include <scmconfig.h> before testing
9163 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
9165 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
9167 * init.c (scm_boot_guile): Add init_func argument; call
9168 (*init_func) instead of calling scm_appinit; it's ucky to
9169 hard-code names for the user's procedures.
9170 * init.h (scm_boot_guile): Adjust declaration.
9172 * __scm.h (PROTO): New macro, for declaring functions with
9175 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
9176 eliminate all the __STDC__ conditionals.
9177 (scm_boot_guile): Add declaration.
9178 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
9179 Remove __STDC__ conditionals around function definitions; the
9180 declarations in init.h will provide the same information, more
9183 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
9184 complain about it in the error message; the error message is
9185 adequate without that note, and there's nothing the user can do
9188 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
9190 * Makefile.in (ancillary): Drop def.sed.
9192 * posix.c (scm_init_posix): Use numeric values, rather than
9193 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
9194 F_OK. The symbols aren't available on some systems, and I'm
9195 pretty sure their values are fixed by common widespread practice.
9196 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
9198 More functions unavailable on some systems.
9199 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
9200 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
9202 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
9203 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
9204 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
9205 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
9206 stub that signals an error as the #else.
9208 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
9210 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
9212 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
9214 * unif.c: include ramap.h.
9216 * read.c (endif): case_insensative_p renamed case_insensitive_p.
9218 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
9220 * ports.c: include sys/ioctl.h.
9222 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
9224 * configure.in: check for sys/ioctl.h.
9226 * ports.c: include <malloc.h> not "malloc.h".
9228 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
9230 * fports.c: remove ttyname and tmpnam declarations.
9232 * posix.c: fewer ttyname declarations.
9234 * fports.c: include <string.h> not "string.h".
9236 * init.c, ioext.c: include string.h and unistd.h.
9238 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
9240 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
9241 genio.c, simpos.c, vports.c: include string.h.
9243 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
9245 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
9247 (scm_addr_buffer_size): change type from scm_sizet to int.
9248 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
9249 from scm_sizet to int.
9251 * error.c: include unistd.h.
9253 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
9256 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
9258 * __scm.hd, def.sed: deleted.
9260 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
9262 Changes for NeXT, suggested by Robert Brown.
9263 * configure.in: Call AC_TYPE_MODE_T.
9264 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
9265 NeXT. Put header file list in alphabetical order.
9266 * configure, scmconfig.h.in: Regenerated.
9267 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
9269 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
9272 * acconfig.h: New file, providing documentation for the CPP
9273 symbols defined in configure.in
9274 * acconfig-1.5.h: Removed; superceded by the above.
9276 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
9278 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
9280 * fports.c (scm_open_file): don't return #f, throw error.
9282 * ioext.c (fileno): renamed from %fileno.
9283 (soft-fileno): deleted.
9285 * ports.c (scm_port_revealed): don't need to check for -1 from
9287 (scm_set_port_revealed_x): return unspecified, not #f.
9289 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
9291 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.

9303 (installed_h_files): Put in alphabetical order.
9304 Remove duplicate entries for markers.h and unif.h.
9305 (c_files): Remove duplicate entries for markers.c.
9306 (ancillary): Renamed from anillery; all uses changed. Remove
9307 PLUGIN; it's a directory, and needs special treatment in dist-dir.
9308 Remove all the ../doc/* files; doc/Makefile.in handles that.
9310 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
9312 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
9313 every if must have an else, or else the whole command has a
9314 non-zero exit code whenever the if's condition is false.
9316 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>

9381 matter so long as it is non-0 (got rid of "* 4").
9383 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
9385 * gscm.h: gscm_mkarray eliminated (presumably was not being used
9386 since its definition was bogus).
9388 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
9390 * mallocs.[ch]: back again (for rx at least).
9392 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
9394 * ports.c: removed functions relating to the mapping between ports
9395 and descriptors. (That stuff is unix-specific and should be collected
9396 in a separate library).

9403 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
9404 handled correctly (SCM_FREEP was applied to them) -- test for
9405 NIMP. Keys in weak hash tables were spuriously (though harmlessly)

9460 * ports.c (scm_add_to_port_table): Added fields

9573 initialization to fix a race condition.
9575 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

9599 set the multi_byte flag correctly in symbols. This is wrong.
9600 intern_obbary_soft and msymbolize should take an extra parameter.

9602 The weird symbol syntax is also a bit bogus (emacs doesn't quite
