1 1999-12-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3 * macros.c (scm_make_synt): Use scm_make_subr_opt to make the
4 transformer subr. (Thanks to Bill Schottstaedt.)
6 1999-12-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
8 * objects.c (scm_class_of): Bugfix: Inserted missing SCM_CDR
9 setting struct table class.
11 Sun Dec 19 10:22:34 1999 Greg J. Badros <gjb@cs.washington.edu>
13 * threads.c, mit-pthreads.c, list.c, coop.c: Remove K&R
14 prototypes; just use ANSI C prototypes. I'm not sure how
15 mit-pthreads.c ever compiled -- it still doesn't for me, but the
16 normal make procedure does not try to build it anyway (even
17 --with-threads I get the other threads code building) so I'm not
20 Sat Dec 18 16:58:34 1999 Greg J. Badros <gjb@cs.washington.edu>
22 * tags.h (SCM_CONSP, SCM_NCONSP): Define these in terms of
23 SCM_SLOPPY_CONSP and SCM_SLOPPY_NCONSP. (SCM_CONSP) Define this
24 in terms of SCM_SLOPPY_NCONSP instead of repeating the
27 * symbols.h (SCM_SLOPPY_SUBSTRP, SCM_SUBSTRP): Added former, and
28 define latter in terms of sloppy variant.
30 * strings.h (SCM_SLOPPY_STRINGP, SCM_STRINGP): Added former, and
31 define latter in terms of sloppy variant.
33 * scm_validate.h (SCM_MAKE_VALIDATE): Added this macro to factor
34 out the commonality of the various basic SCM_VALIDATE_foop
35 macros. Use SCM_MAKE_VALIDATE macro where possible. Fix
36 SCM_VALIDATE_INT_COPY to not use scm_num2ulong -- that does
37 coercion to an integer which is more advanced than desired and
38 SCM_NUM2ULONG provides that functionality. Use SCM_ASSERT_RANGE
39 appropriately for the various _MIN, _MAX, _RANGE macros. Drop
40 some superfluous "SCM_NIMP &&" where possible. Eliminate obsoleted
41 SCM_VALIDATE_NIMCONS (SCM_VALIDATE_CONS now does the NIMP test as
42 part of its SCM_CONSP test).
44 * socket.c, ports.c, pairs.c, list.c, lang.c, async.c: Use
45 SCM_VALIDATE_CONS, not obsoleted SCM_VALIDATE_NIMCONS.
47 Sat Dec 18 15:33:05 1999 Greg J. Badros <gjb@cs.washington.edu>
49 * dynl.c: Added #include "scm_validate.h"
51 Sat Dec 18 15:22:10 1999 Greg J. Badros <gjb@cs.washington.edu>
53 * alist.c, chars.c, dynl.c, net_db.c, numbers.c, unif.c: Use
54 SCM_NUM2ULONG instead of scm_num2ulong; SCM_NUM2LONG instead of
55 scm_num2long; SCM_WTA instead of scm_wta. Only done for when
56 FUNC_NAME was used as an argument of the macro and the formal
57 argument name was the explicit argument in the old function call.
58 These were just missed in my first pass of changes.
60 1999-12-18 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
62 * guile-doc-snarf.in (filename): Strip path to source dir before
63 touching the .x-files.
65 1999-12-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
67 * debug.c (scm_reverse_lookup): Bugfix: Reinserted SCM_NIMP.
69 * eval.c (SCM_CEVAL): Removed check for unbound slot in
70 SCM_IM_SLOT_REF. (This is now handled in a smarter way in GOOPS.)
72 1999-12-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
74 * tags.h (SCM_SLOPPY_NCONSP, SCM_SLOPPY_CONSP): New macros.
75 (SCM_ECONSP): Version which doesn't mix && and || without
77 (SCM_NECONSP): Bugfree version.
79 Fri Dec 17 12:09:11 1999 Greg J. Badros <gjb@cs.washington.edu>
81 * tags.h (SCM_ECONSP, SCM_NECONSP): Fix these macros to have the
82 SCM_NIMP test integrated into an || clause that I'd missed before
83 and was causing a segfault in the regression tests.
85 * symbols.h (SCM_ROUCHARS): Make cast be to (unsigned char *), not
86 (char *); fixes a problem reported by the regression test
89 * ports.c: Fixed a couple of arg/number mismatches in
92 Now passes the (not-comprehensive) guile-modules test-suite again!
94 Thu Dec 16 12:41:22 1999 Greg J. Badros <gjb@cs.washington.edu>
96 * coop-threads.c: Remove K&R function headers.
98 * scm_validate.h: Added SCM_VALIDATE_THREAD.
100 * *.c: Remove SCM_NIMP(X) when it is an extraneous pre-test given
101 that SCM_FOOP macros all now include SCM_NIMP in their expansion.
102 This simplifies lots of code, making it far more readable.
104 Wed Dec 15 19:45:14 1999 Greg J. Badros <gjb@cs.washington.edu>
106 * *.h: Use SCM_NIMP(X) && in all the FOOP macros.
108 * *.[ch]: Use do { ... } while (0) idiom in macros that expanded
111 Tue Dec 14 10:53:14 1999 Greg J. Badros <gjb@cs.washington.edu>
113 * snarf.h: Put SCM_PROC and SCM_PROC1 back in for
114 backward-compatibility of packages that use Guile. Internally
115 Guile should not use them, though. (Maybe enforce this with a new
116 -DBUILDING_GUILE compile-time flag?).
118 Tue Dec 14 09:41:01 1999 Greg J. Badros <gjb@cs.washington.edu>
120 * backtrace.c (scm_set_print_params_x): Renamed from
123 * guile-doc-snarf.in: Use guile-snarf.awk, not
124 guile-doc-snarf.awk. Pass the basename of $filename
126 * load.h: Added prototypes for scm_sys_library_dir,
129 * load.c (scm_sys_library_dir, scm_sys_site_dir): Added these
130 functions, and took out the old scm_library_dir, scm_site_dir,
131 scm_pkgdata_dir. Now the primitives are %package-data-dir
132 (already existed), %library-dir, and %site-dir.
134 * debug.c: Use SCM_MISC_ERROR when possible instead of using
135 s_scm_* in a scm_misc_error() call.
137 * Makefile.am: Use guile-snarf.awk, not guile-doc-snarf.awk. Make
138 using guile-doc-snarf send stdout to $@ to create the .x file like
141 * guile-snarf.awk.in: Added.
143 * guile-doc-snarf.awk.in: Removed (sorry to back out a recent
144 commit; if we're going to switch to guile-snarf I figure it makes
145 sense to get this right now-- I'd already had the change in my
146 working copy when the below commit happened).
148 1999-12-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
150 * guile-doc-snarf.awk: Removed.
152 * guile-doc-snarf.awk.in: Added.
154 * ports.c (s_scm_pt_member): Fixed validation.
156 * guile-doc-snarf.in (filename): Use basename in order to strip
159 * debug.c (scm_make_iloc, s_scm_proc_to_mem): Added missing
161 (scm_memcons, scm_memcons, mem_to_proc): Renamed function name
164 * backtrace.c (set_print_params_x): Fixed GUILE_PROC macro.
166 * tags.h (SCM_UNBOUND): New iflag which is needed for some time to
167 mark the unboundness of a GOOPS slot. (Added now in order to
168 correct a oversight. Should probably be removed again and
169 replaced with SCM_UNDEFINED when the corresponding code in GOOPS
172 * print.c (scm_isymnames): Added printed representation for
175 * eval.c (SCM_CEVAL): Bugfix: Added check for unbound slot in
178 Mon Dec 13 17:23:22 1999 Greg J. Badros <gjb@cs.washington.edu>
180 * strings.c: Fixed mistaken default value in
181 scm_make_shared_substring; thanks Eric Moore!
183 Mon Dec 13 16:29:13 1999 Greg J. Badros <gjb@cs.washington.edu>
185 * guile-doc-snarf.awk: Use sub instead of gsub in ^ anchored
186 replacement for docstrings. Fixes problem Ryan Yeske observed
187 with using mawk on his system. Thanks Ryan!
189 Mon Dec 13 13:30:06 1999 Greg J. Badros <gjb@cs.washington.edu>
191 * guile-doc-snarf.in: Do not echo to stdout since the output now
192 gets stuck directly in the files instead of redirected from
195 * guile-doc-snarf.awk: Escape a literal ) -- thanks Ryan
196 Yeske. Use print instead of printf to prime the .x file since
197 AIX's cpp has problems with #include-ing empty files (according to
198 the old guile-snarf.in file).
200 Sun Dec 12 19:39:00 1999 Greg J. Badros <gjb@cs.washington.edu>
202 * Makefile.am: Fix ETAGS_ARGS to recognize GUILE_PROC,
203 GUILE_PROC1. Build guile-procedures.txt, and add that file to
206 * load.c: Added `pkgdata-dir', `site-dir', `library-dir'
209 * guile-doc-snarf.awk: Drop trailing space when no arguments:
210 e.g., "(foo )" is now "(foo)".
212 * *.c, alist.c: moved all the documentation for primitives from
213 guile-doc/ref/{appendices,posix,scheme}.texi into the source code.
214 This leaves about half of the primitives undocumented. Also, all
215 the markup is currently still texinfo. I don't have a problem
216 with texinfo per se, but the markup is not very descriptive or
219 Sun Dec 12 16:50:26 1999 Greg J. Badros <gjb@cs.washington.edu>
221 * scm_validate.h: Drop the SCM_DOCSTRING_SNARF for turning off
222 SCM_VALIDATE macros; the SCM_VALIDATE macros should be checked for
223 argument mismatches (along with the FUNC_NAME macro checking) by a
224 static tool that runs directly over the .c files.
226 * snarf.h: Handle SCM_REGISTER_PROC better when snarfing. The
227 docstring is still missing from the .doc file; it just gives the
228 name of the C function that gets called instead.
230 * guile-doc-snarf.awk: Be sure to touch the output files to help
231 make out. Also handle SCM_REGISTER_PROC better, and change the
232 output format slightly.
234 Sun Dec 12 15:33:40 1999 Greg J. Badros <gjb@cs.washington.edu>
236 * snarf.h: Drop SCM_PROC, SCM_PROC1. Added extra output for
237 guile-doc-snarf script.
239 * guile-doc-snarf.in, guile-doc-snarf.awk: New, simple doc
240 extraction system. Builds foo.x, foo.doc from foo.{c,cc}.
241 There are dependencies between these files and snarf.h. This
242 replaces guile-snarf.
244 * guile-snarf.in: Drop everything after $$$ for the new snarf.h
245 macros. This is obsoleted by guile-doc-snarf, but kept here for
246 now for good measure.
248 * Makefile.am: Added guile-doc-snarf, guile-doc-snarf.awk to
249 bin_SCRIPTS. Added .doc to SUFFIXES, and give rule for creating
250 .doc files to use guile-doc-snarf. Update the rule for creating
251 .x files to use guile-doc-snarf.
253 Sun Dec 12 12:31:38 1999 Greg J. Badros <gjb@cs.washington.edu>
255 * *.c: Finish replacing K&R style prototypes with ANSI C
258 * eval.c: Make scm_m_mody's 3rd argument be a const char *, not a
259 char *. ANSI prototypes caught this.
261 * strorder.c: Use GUILE_PROC1 for the couple SCM_PROC1 expansions
264 * scm_validate.h: Use SCM_BOOLP for validating bools. Do not
265 expand macros if SCM_DOCSTRING_SNARF.
267 Sun Dec 12 11:23:22 1999 Greg J. Badros <gjb@cs.washington.edu>
269 * *.c, srcprop.h: Use SCM_BOOL(f) instead of (f? SCM_BOOL_T:
270 SCM_BOOL_F) and use SCM_NEGATE_BOOL(f) instead of (f? SCM_BOOL_F:
273 Sun Dec 12 11:08:51 1999 Greg J. Badros <gjb@cs.washington.edu>
275 * boolean.h: Added SCM_BOOL, SCM_NEGATE_BOOL, SCM_BOOLP to here,
278 * scm_validate.h: Moved above out into boolean.h, fix typo in
279 SCM_VALIDATE_NIM macro.
281 Sun Dec 12 10:29:12 1999 Greg J. Badros <gjb@cs.washington.edu>
283 * *.c, scm_validate.h: Use SCM_VALIDATE_NIM, not SCM_VALIDATE_NIMP
284 (none of the other validate macros have the trailing P).
286 Sun Dec 12 10:07:29 1999 Greg J. Badros <gjb@cs.washington.edu>
288 * scm_validate.h: Added the FSF copyright to the top.
290 * strings.c: Use SCM_ASSERT_RANGE in a couple of places instead of
291 SCM_ASSERT w/ SCM_OUT_OF_RANGE.
293 Sat Dec 11 18:34:12 1999 Greg J. Badros <gjb@cs.washington.edu>
295 * Makefile.am: Added scm_validate.h to modinclude_HEADERS.
297 * *.c: Pervasive software-engineering-motivated rewrite of
298 function headers and argument checking. Switched SCM_PROC,
299 SCM_PROC1 macros to be GUILE_PROC, GUILE_PROC1 (may change names
300 later, but was useful to keep old versions around while migrate)
301 that has docstrings and argument lists embedded in the GUILE_PROC
302 macro invocations that expand into a function header. Use lots of
303 new SCM_VALIDATE_* macros to simplify error checking and reduce
304 tons of redundancy. This is very similar to what I did for Scwm.
306 Note that none of the extraction of the docstrings, nor software
307 engineering checks of Scwm is yet added to Guile. I'll work on
308 that tomorrow, I expect.
310 * chars.c: Added docstrings for the primitives defined in here.
312 * snarf.h: Added GUILE_PROC, GUILE_PROC1. Added
313 SCM_REGISTER_PROC to be like old SCM_PROC, though old SCM_PROC
314 still remains for now. Changed naming convention for the s_foo
315 string name of the primitive to be s_scm_foo for ease of use with
318 * scm_validate.h: Lots of new SCM_VALIDATE macros to simplify
319 argument checking through guile. Maybe some of these should be
320 folded into the header file for the types they check, but for now
321 it was easiest to just stick them all in one place.
323 1999-12-10 Greg Harvey <Greg.Harvey@thezone.net> (applied --12/10/99 gjb)
325 * smob.c (scm_smob_prehistory): initialize allocated smob
327 * tags.h: new tag: scm_tc16_allocated
329 * gc.c (scm_gc_for_newcell): set the car of the new cell
330 to scm_tc16_allocated
331 * pairs.h (SCM_NEWCELL): set the car to scm_tc16_allocated
332 (scm_gc_mark): mark allocated cells.
334 1999-12-09 Greg J. Badros <gjb@cs.washington.edu>
336 * strports.h, strports.c (scm_eval_0str): Fix constness. Some
337 thanks to Dirk Hermann.
339 * gh_eval.c (gh_eval_str, gh_eval_file, gh_eval_str_with_catch,
340 gh_eval_str_with_standard_handler,
341 gh_eval_str_with_stack_saving_handler): Fix constness. Some
342 thanks to Dirk Hermann.
344 * gh_data.c (gh_str02scm): Fix constness.
346 * gh.h: Fix constness of prototypes for the above.
348 * vectors.c: Include "unif.h" to avoid a warning about missing
349 prototype for scm_uniform_element_size().
351 1999-12-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
353 * vectors.c (scm_vector_length, scm_vector_ref, scm_vector_set_x):
354 Turned into primitive generics.
356 1999-12-04 Gary Houston <ghouston@freewire.co.uk>
358 * ports.c (scm_port_closed_p): new procedure, implements
359 "port-closed?" suggested by Bernard Urban.
360 ports.h: added prototype, removed the SCM_P macros.
362 1999-11-30 Gary Houston <ghouston@freewire.co.uk>
364 * unif.h: added some comments, removed the SCM_P macros.
366 1999-11-29 Gary Houston <ghouston@freewire.co.uk>
368 * vports.c (sf_write): use scm_makfromstr, not scm_makfrom0str
369 (thanks to Daniel Skarda).
371 1999-11-22 Jim Blandy <jimb@savonarola.red-bean.com>
373 * gscm.c, gscm.h: Deleted. They were unused.
375 1999-11-20 Gary Houston <ghouston@freewire.co.uk>
377 * unif.c (scm_list_to_uniform_array): call
378 scm_dimensions_to_uniform_array with a third argument of
379 SCM_UNDEFINED instead of SCM_EOL.
381 1999-11-19 Gary Houston <ghouston@freewire.co.uk>
383 * the following changes allow guile to be built with the array
384 "module" omitted. some of this stuff is just tc7 type support,
385 which wouldn't be needed if uniform array types were converted
388 * tag.c (scm_utag_bvect ... scm_utag_cvect): don't define unless
390 (scm_tag): don't check array types unless HAVE_ARRAYS.
392 * sort.c (scm_restricted_vector_sort_x, scm_sorted_p):
393 remove the unused array types.
394 * (scm_stable_sort, scm_sort): don't support vectors if not
395 HAVE_ARRAYS. a bit excessive.
397 * random.c (vector_scale, vector_sum_squares,
398 scm_random_solid_sphere_x, scm_random_hollow_sphere_x,
399 scm_random_normal_vector_x): don't define unless HAVE_ARRAYS.
401 * gh_data.c (makvect, gh_chars2byvect, gh_shorts2svect,
402 gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect, gh_doubles2dvect,
403 gh_uniform_vector_length, gh_uniform_vector_ref):
404 don't define unless HAVE_ARRAYS.
405 (gh_scm2chars, gh_scm2shorts, gh_scm2longs, gh_scm2floats,
407 don't check vector types if not HAVE_ARRAYS.
409 * eq.c (scm_equal_p), eval.c (SCM_CEVAL), print.c (scm_iprin1),
410 gc.c (scm_gc_mark, scm_gc_sweep), objects.c (scm_class_of):
411 don't support the array types unless HAVE_ARRAYS is defined.
413 * tags.h: make nine tc7 types conditional on HAVE_ARRAYS.
415 * read.c (scm_lreadr): don't check for #* unless HAVE_ARRAYS is
416 defined (this should use read-hash-extend).
418 * ramap.c, unif.c: don't check whether ARRAYS is defined.
420 * vectors.c (scm_vector_set_length_x): moved here from unif.c. call
421 scm_uniform_element_size if HAVE_ARRAYS.
422 vectors.h: prototype too.
424 * unif.c (scm_uniform_element_size): new procedure.
426 * init.c (scm_boot_guile_1): don't call scm_init_ramap or
427 scm_init_unif unless HAVE_ARRAYS is defined.
429 * __scm.h: don't define ARRAYS.
431 * Makefile.am (EXTRA_libguile_la_SOURCES): unif.c and ramap.c
432 moved here from libguile_la_SOURCES.
434 1999-11-18 Gary Houston <ghouston@freewire.co.uk>
436 * socket.c (scm_htons, scm_ntohs, scm_htonl, scm_ntohl): new
437 functions for network data conversion.
439 * numbers.c (scm_num2long, scm_num2longlong):
440 throw out-of-range instead of wrong-type-arg if appropriate.
441 (scm_iint2str): handle -2^31 correctly.
442 (scm_num2long): handle -2^31 bignum correctly.
443 (scm_num2long_long): rewrite the bigdig case: basically copied
445 numbers.h: (SCM_BITSPERLONGLONG): deleted.
447 * unif.c (rapr1): use sprintf instead of intprint for unsigned
448 longs: intprint can't cope with large values.
450 * numbers.c (scm_num2ulong): check more consistently that the
451 input is not negative. if it is, throw out-of-range instead of
454 * ramap.c (scm_array_fill_int): don't limit fill to INUM for
455 uvect, ivect or llvect.
456 Check that fill doesn't overflow short uniform array.
458 * __scm.h: add another long to the definition of long_long and
461 * unif.c (scm_raprin1): use 'l' instead of "long_long" in the
462 print representation of llvect. read can't handle more than
464 (scm_dimensions_to_uniform_array): make "fill" an optional argument
465 instead of a rest argument.
467 * tags.h (scm_tc7_llvect): wasn't defined anywhere, so use the free
470 * __scm.h: don't mention LONGLONGS.
472 * unif.c, numbers.c, eq.c, gc.c, print.c, eval.c, ramap.c:
473 replace LONGLONGS with HAVE_LONG_LONGS as set by configure.
475 1999-11-17 Gary Houston <ghouston@freewire.co.uk>
477 * net_db.c (scm_inet_aton): throw errors using the misc-error key
478 instead of system-error. inet_aton doesn't set errno.
479 system-error isn't right in gethost either, since it's throwing
480 the value of h_errno instead of errno. so:
481 (scm_host_not_found_key, scm_try_again_key,
482 scm_no_recovery_key, scm_no_data_key): new error keys.
483 (scm_resolv_error): new procedure, use the new keys.
484 (scm_gethost): call scm_resolv_error not scm_syserror_msg.
486 1999-11-16 Gary Houston <ghouston@freewire.co.uk>
488 * error.c: (various): use scm_cons instead of scm_listify
489 to build short lists.
491 1999-11-03 Gary Houston <ghouston@freewire.co.uk>
493 * socket.c (scm_fill_sockaddr): zero the address structure before
494 use, in case it has a sin_len field and the OS doesn't like random
495 values (thanks to Bertrand Petit).
497 1999-10-26 Mark Galassi <rosalia@lanl.gov>
499 * gh.h, gh_data.c (gh_symbol2scm): changed gh_symbol2scm() to take
500 a const char * argument, upon suggestion from Lynn Winebarger.
502 1999-10-26 Gary Houston <ghouston@freewire.co.uk>
504 * strports.c (st_end_input): avoid dubious pointer arithmetic.
506 1999-10-24 Gary Houston <ghouston@freewire.co.uk>
508 * Move the responsibility for resetting port buffers from the
509 caller of the ptob seek procedure to the implementation. This
510 gives more control in general to the ptob seek: in particular the
511 change of 1999-10-20 can be made to work without breaking seek on
512 string ports. There's a comment in NEWS about upgrading port
515 * ports.c (scm_seek): don't reset the port buffers here.
517 * fports.c (fport_seek): reset the buffers, except for the
520 * strports.c (st_end_input): (bug fix): decrement pt->read_pos by
521 offset. check that it's not less than read_buf.
522 (st_seek): reset the buffers first, unless it's the 0 SEEK_CUR
523 case and currently reading.
525 1999-10-20 Gary Houston <ghouston@freewire.co.uk>
527 * ports.c (scm_seek): Add a special case for SEEK_CUR, offset 0,
528 so that unread chars are not needlessly discarded. (thanks to
531 1999-10-18 Gary Houston <ghouston@freewire.co.uk>
533 * fports.c (scm_fdes_to_port): always set rw_random if the fdes is
534 random access. rw_active needs to be maintained even for single
535 directional ports, otherwise scm_seek and probably other things are
536 broken. (thanks to Roland Orre).
538 * strports.c (scm_mkstrport): set rw_random to 1 unconditionally.
540 * ports.c (scm_add_to_port_table): initialise rw_random to 0.
542 * ports.h (scm_port): change the comments on rw_random and rw_active.
544 1999-10-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
546 * ioext.c: Added #include "feature.h".
548 These changes turns `delay' into a memoizing macro. This is
549 because it may be expanded before evaluation if it occurs at the
550 beginning of a body. (Thanks to Lauri Alanko.)
552 * eval.c, eval.h (scm_sym_delay): New global symbol.
554 * tags.h (SCM_IM_DELAY): New immediate symbol.
556 * print.c (scm_isymnames): Printed representation.
558 * eval.c (unmemocopy, SCM_CEVAL): Handle SCM_IM_DELAY.
559 (scm_m_delay): Turned into a memoizing macro.

563 1999-10-11 Jim Blandy <jimb@savonarola.red-bean.com>
565 * gh_data.c (gh_ints2scm, gh_doubles2scm): Make sure elements are
566 protected from GC while building the vector. (Thanks to Bernard
567 Urban and Greg Harvey.)
569 1999-10-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
571 * throw.c (handler_message): Display backtrace if backtraces
574 1999-10-05 Jim Blandy <jimb@savonarola.red-bean.com>
576 * Makefile.in, scmconfig.h.in: Deleted from CVS repository. Run
577 the autogen.sh script to create generated files like these.
579 * numbers.c (scm_string_to_number): Signal an error if radix is
580 less than two. (Thanks to Jorgen Schaefer.)
582 * print.c (scm_write, scm_display, scm_newline, scm_write_char):
583 Don't assume that the current output port is valid. Somebody
584 might close it. (Thanks to Bernard Urban.)
586 1999-10-02 Jim Blandy <jimb@zwingli.cygnus.com>
588 * scmconfig.h.in: Regenerated.
590 * Makefile.am (EXTRA_libguile_la_SOURCES): fix typo.
592 Mon Sep 27 17:15:14 1999 Greg J. Badros <gjb@cs.washington.edu>
594 * __scm.h: Fix a bunch of macros that were missing do-while(0)
597 * debug.c, eval.c: Fix buggy uses of SCM_ALLOW_INTS (missing
598 semicolon) exposed by the above change.
600 1999-09-27 Greg J. Badros <gjb@cs.washington.edu>
602 * stacks.c: Avoid compiler warning re: unitialized var.
604 * scmconfig.h.in: Added DEBUG_FREELIST
606 * pairs.h: Fix macro that was not do-while(0) sandwiched.
608 * gc.h, gc.c: Added scm_gc_set_debug_check_freelist_x,
611 1999-09-23 Gary Houston <ghouston@freewire.co.uk>
613 * ioext.c (scm_init_ioext): enable "i/o-extensions" feature here
614 instead of in scm_init_filesys.
616 * init.c (scm_boot_guile_1): don't call scm_init_posix or
617 scm_init_filesys unless HAVE_POSIX is defined.
618 don't call scm_init_netdb or scm_init_socket unless
619 HAVE_NETWORKING is defined.
621 * Makefile.am (EXTRA_libguile_la_SOURCES): filesys.c, posix.c,
622 net_db.c, socket.c: moved here from libguile_la_SOURCES.
624 1999-09-25 Jim Blandy <jimb@savonarola.red-bean.com>
626 * root.c (scm_make_root): Initialize all the fields of the new
627 root. GC could happen any time, you know. (Thanks to Greg
630 * numbers.c (scm_number_to_string): Signal an error if radix is
631 less than two. (Thanks to Jorgen Schaefer.)
633 * Makefile.am (EXTRA_libguile_la_SOURCES): Add memmove.c here,
634 so automake will actually generate rules for it.
635 * Makefile.in: Regenerated.
637 1999-09-21 Jim Blandy <jimb@savonarola.red-bean.com>
639 * backtrace.c: #include "_scm.h" before testing whether
640 HAVE_UNISTD_H is #defined.
642 1999-09-20 Jim Blandy <jimb@savonarola.red-bean.com>
644 * read.c (scm_read): Don't assume that scm_cur_inp is always open.
645 * ports.c (scm_read_char): Same.
646 * ioext.c (scm_read_line): Same.
647 (Thanks to Bernard Urban.)
649 1999-09-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
651 * vectors.c (scm_vector_move_right_x): Bugfix: Remove side effect
653 numbers.c: Removed #ifndef SCM_RECKLESS at places where type
654 checking may invoke a generic. (Thanks to Michael Livshin.)
656 * __scm.h (SCM_WTA_DISPATCH_0, SCM_GASSERT0): New macros.
658 * numbers.c (scm_max, scm_min, scm_sum, scm_difference,
659 scm_product, scm_divide): Bugfix: Don't pass SCM_UNDEFINED to the
660 generic function if the asubr is called with only one arg.
662 1999-09-20 Gary Houston <ghouston@freewire.co.uk>
664 * scmsigs.c (scm_sigaction): add SA_RESTART to flags only if
665 HAVE_RESTARTABLE_SYSCALLS.
666 (scm_init_scmsigs): use siginterrupt if it's available. not
667 everyone who has restartable syscalls has SA_RESTART it seems.
669 (scm_sigaction): use scm_num2long/scm_long2num when converting
670 SIG_DFL/SIG_IGN, in case it doesn't fit in an INUM. use
671 scm_integer_p to test the type.
673 1999-09-18 Gary Houston <ghouston@freewire.co.uk>
675 * _scm.h, scmsigs.c: replace HAVE_RESTARTS with
676 HAVE_RESTARTABLE_SYSCALLS.
678 * strports.c (scm_strport_to_string): create the string from
679 pt->read_buf instead of an expression that evaluates to the
682 * gdbint.c (gdb_print): don't just use SCM_CHARS to get a C string
683 from the port: the port's buffer may not be NUL terminated.
685 1999-09-16 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
687 * Makefile.am (.c.x): Added missing semicolon after `false'.
689 1999-09-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
691 * print.c (scm_iprin1): Turn `write' and `display' into
692 primitive generics and use their associated generic functions in
693 scm_iprin1 for GOOPS objects.
695 * backtrace.c: #include <unistd.h> if present.
697 1999-09-14 Jim Blandy <jimb@savonarola.red-bean.com>
699 * Makefile.am (.c.x): Don't create a subshell just to delete the
700 .x file and return false.
701 * Makefile.in: Regenerated.
703 1999-09-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
705 * feature.c (scm_create_hook): New function. Replaces
706 scm_make_named_hook which is now deprecated.
707 (scm_make_hook_with_name): New primitive.
708 (print_hook): Hooks now print in a fancy way.
710 1999-09-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
712 * __scm.h, backtrace.c, backtrace.h, debug.c, debug.h, dynl-dld.c,
713 dynwind.c, dynwind.h, eval.h, evalext.c, evalext.h, feature.c,
714 feature.h, hashtab.c, hashtab.h, objects.c, objects.h, print.c,
715 procs.c, procs.h, smob.c, smob.h, srcprop.c, strorder.c, struct.c,
716 struct.h: Updated copyright notices.
718 * srcprop.c (scm_source_property): Bugfix: Use SCM_NECONSP instead
719 of SCM_NCONSP. (Thanks to Greg Badros.)
721 * gsubr.c (scm_make_gsubr): Use scm_make_subr_opt for creation of
724 * eval.c, debug.h (SCM_BACKTRACE_WIDTH): New debug option: width.
726 * backtrace.c: Keep backtraces within specified width by
727 adaptively adjusting fancy printing parameters and cut output if
729 (scm_display_application): Check args.
731 1999-09-11 Jim Blandy <jimb@savonarola.red-bean.com>
733 Change the name of the objects returned by OPENDIR from
734 "directory" to "directory stream". A predicate named "directory?"
736 * filesys.c (scm_directory_stream_p): Renamed from scm_directory_p.
737 At the Scheme level, "directory?" -> "directory-stream?".
738 (scm_dir_print): Use the phrase "directory stream" in printed form.
739 * filesys.h (scm_directory_stream_p): Prototype renamed
742 * Makefile.am (CLEANFILES): Remove versiondat.h; that should only
743 be removed by `make distclean', since it's generated by configure.
744 * Makefile.in: Regenerated.
745 (Thanks to Robert Bihlmeyer.)
747 * strop.c (scm_substring_move_x): Signal an error if start1
748 doesn't come before end1. (Thanks to Karoly Lorentey).
750 * numbers.c (scm_istr2flo): Don't call SCM_INEXP without first
751 calling SCM_NIMP. (Thanks to Karoly Lorentey).
753 * version.c (scm_libguile_config_stamp): Deleted. See
754 corresponding change to ../ice-9/boot-9.scm.
755 * versiondat.h.in: Remove definition for GUILE_STAMP.
756 * version.h: Delete prototype.
757 * Makefile.in: Regenerated.
759 1999-09-11 Gary Houston <ghouston@easynet.co.uk>
761 * filesys.c (scm_directory_p): new procedure "directory?" Returns
762 a boolean indicating whether its argument is a directory
763 port as returned by opendir (thanks to Dirk Herrmann for the
766 1999-09-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
768 * backtrace.c (display_frame_expr): Don't print a newline.
769 (display_frame): Print the newline here instead.
770 (display_backtrace_body): Don't print "Backtrace:".
771 (scm_backtrace): Print "Backtrace:" here instead.
773 1999-09-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
775 * procs.c (scm_setter): Signal WTA if handed an entity or operator
778 * feature.c, feature.h: (scm_hook_p, scm_hook_empty_p): New
779 primitives. (Thanks to Greg Badros);
780 (scm_hook_to_list): New primitive; Hooks are now smobs.
782 1999-09-08 Gary Houston <ghouston@easynet.co.uk>
784 * stime.c (bdtime2c): rewrite the ASSERTs. Accept a value
785 of #f for the 10th vector element to avoid an exception
786 seen by Bernard Urban.
787 (scm_mktime): unneeded ASSERT removed.
789 1999-09-07 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
791 * eval.c (scm_map, scm_for_each): Converted to dispatch on generic
794 * __scm.h (SCM_WTA_DISPATCH_n, SCM_GASSERTn): New macros.
796 1999-09-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
798 * numbers.c: Converted comparison operations to dispatch on
799 generic if args don't match.
801 * Makefile.am (ETAGS_ARGS): Added support for GPROC and GPROC1.
803 1999-09-06 James Blandy <jimb@mule.m17n.org>
805 * guile-snarf.c: Deleted. Snarfing should respect CPP
806 conditionals, so it needs to actually run CPP. Bleah.
808 1999-09-05 James Blandy <jimb@mule.m17n.org>
810 Handle errors properly in guile-snarf. (Thanks to Han-Wen Nienhuys.)
811 * guile-snarf.in: Be sure to exit with an error if CPP does.
812 * Makefile.am (.c.x): Delete the .x file and exit with an error
813 status if guile-snarf exits with an error status.
814 * Makefile.in: Regenerated.
816 * snarf.h (SCM_GLOBAL_KEYWORD): Call scm_c_make_keyword, not
817 scm_makekey, which doesn't exist any more. Guess nobody's using
820 * guile-snarf.c: New implementation of guile-snarf, meant to be
821 more robust than the shell script. I think it's complete, but I
822 haven't tested it at all, and I haven't changed the build process
823 to actually use it. We should compare its output against that of
824 the existing shell script, for all source files.
826 * guile-snarf.c (parse_args): Abort if we haven't handled some
829 1999-09-03 James Blandy <jimb@mule.m17n.org>
831 * load.c (scm_search_path): If the filename has any extension at
832 all, ignore the entire list of extensions. Also, don't check whether
833 the file is accessible. If the file exists, accessible or not, we
834 should return it. Inaccessible files should cause an error later.
835 (Thanks to Keisuke Nishida for the suggestions.)
837 1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
839 * gc.c (cleanup, scm_init_storage): Use on_exit if present and
840 atexit not available. (sunos4.1.4 needs it.)
842 1999-09-01 James Blandy <jimb@mule.m17n.org>
844 I take it all back --- bcopy does handle overlapping source and
845 destination areas correctly. At least on every system I could
846 find. But it is better to use AC_REPLACE_FUNCS than to introduce
847 new CPP conditionals.
848 * memmove.c: New file, implementing memmove in terms of bcopy.
849 * scmconfig.h.in: Regenerated.
851 Allocators should use the `void *' type for generic pointers.
852 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
853 argument and return types.
854 * gc.h: Corresponding changes to prototypes.
857 1999-08-31 James Blandy <jimb@mule.m17n.org>
859 * numbers.c (scm_init_numbers): Claim to support the `complex'
860 feature, as expected by (ice-9 format). (Thanks to Ceri Storey.)
862 * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
863 find (ice-9 boot-9) when Guile was compiled in a separate
864 directory from the source. (Thanks to Rodney Brown.)
865 * Makefile.in: Regenerated.
867 * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply
868 table lengths by the size of a single element when growing the
869 table. (Thanks to Bill Schottstaedt.)
871 1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
873 * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
874 SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
875 since that cuts down the time for type dispatch by 50%.
877 1999-08-30 James Blandy <jimb@mule.m17n.org>
879 * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
880 not a correct substitute for memmove, because it doesn't handle
881 overlapping source and destination areas on many platforms.
882 Overlaps are the primary reason to use memmove in the first place.
883 * ports.c (scm_ungetc): Same.
884 * strop.c (scm_substring_move_x): Same.
886 1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
888 * gc.c (scm_init_storage): Skip registration of cleanup on systems
889 which lack atexit. (Is it important that cleanup is made
890 properly? Maybe we should replace all `exit' with `scm_exit' and
893 * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
894 scm_struct_free_standard, scm_struct_free_entity): Declared to
895 return scm_sizet instead of size_t.
897 * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined
898 there on sunos4.1.4.)
900 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
902 * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
903 Account for the case when second argument is unbound.
905 * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
906 (Thanks to Karoly Lorentey.)
908 * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
909 isn't present. (Thanks to Suzuki Toshiya.)
911 * ports.c: Use ANSI C prototypes in definitions. (Thanks to
914 * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
917 * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
918 Bernard Urban and Ian Grant.)
920 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
921 again. (1.3.4 will be binary incompatible with 1.3.2 because of a
922 change in the representation of entities and operators.)
924 1999-08-29 Gary Houston <ghouston@easynet.co.uk>
926 * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
927 don't allocate zero bytes (thanks to Bill Schottstaedt).
929 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
931 * procs.c (scm_setter): Converted to use generic dispatch.
933 * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
936 * load.c (scm_search_path): Don't try extensions which already are
937 present at the end of the filename.
938 (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
940 * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
942 Cleanup and simplification of generic method dispatch.
943 Also, the quadruple representation of entity and operator
944 procedures has been replaced with single.
946 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
948 * print.c (scm_isymnames): Removed #@hash-dispatch.
950 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
951 from eval.c; Support 0 arity methods.
952 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
953 (scm_apply_generic_env): Removed.
954 Replaced slots proc0-3 with procedure.
956 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
957 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
958 SCM_OPERATOR_PROCEDURE.
959 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
960 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
962 * struct.c, struct.h: Replace 4 procedure slots with one.
963 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
965 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
968 * eval.c (scm_sym_args): Removed.
969 (SCM_CEVAL): Simplified entity application.
970 Moved dispatch code to objects.c.
972 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
974 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
976 * sort.c (closureless): Use scm_eval_body.
978 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
979 with a symbol as last form was first called normally and then via
980 `map' or some other mechanism using primitive apply, an ILOC was
983 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
985 This change extends the representation of primitive procedures
986 with more data fields, e.g. a place for documentation and true
987 procedure properties.
989 * procs.c, procs.h (scm_subr_entry): New type: Stores data
990 associated with subrs.
991 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
992 SCM_SUBR_DOC): New macros.
993 (scm_subr_table): New variable.
994 (scm_mark_subr_table): New function.
996 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
998 * gc.c (scm_gc_mark): Don't mark subr names here.
999 (scm_igc): Call scm_mark_subr_table.
1002 This change implements a scheme for letting a generic work as a
1003 shadow for a primitive procedure. If the primitive procedure
1004 can't dispatch on its arguments, control is left over to the
1005 generic. Normal wrong type arg errors will be generated until the
1006 user has hung the first method on the primitive.
1008 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
1010 * procs.c, procs.h (scm_subr_p): New function (used internally).
1012 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
1014 * objects.c, objects.h (scm_primitive_generic): New class.
1016 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
1018 * print.c (scm_iprin1): Print primitive-generics.
1020 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
1021 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
1023 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
1024 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
1025 primitives). NOTE: This means that it is now *required* to use
1026 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
1027 obscured representation that will be removed in the future anyway,
1028 so backward compatibility is no problem here).
1030 * numbers.c: Converted most numeric primitives (all but bit
1031 comparison operations and bit operations) to dispatch on generic
1032 if args don't match.
1035 Better support for applying generic functions.
1037 * eval.c, eval.h (scm_eval_body): New function.
1039 * objects.c (scm_call_generic_0, scm_call_generic_1,
1040 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
1044 Optimization of the generic function dispatch mechanism.
1046 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
1047 called scm_memoize_method instead of doing a second lookup.
1049 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
1054 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
1055 scm_sysintern so that the binding connected with the subr name
1056 isn't cleared when we give set = 0.
1059 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1061 More transparent handling of ports with print states.
1063 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
1064 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
1065 instead of a pair of a port and a print state. We'll need to cons
1066 once extra in scm_printer_apply but the type system will be
1067 cleaner, it will mix better with GOOPS, and, it will be even more
1068 transparent to the user.
1070 * print.c (scm_get_print_state): New procedure: Given an output
1071 port, return the print state associated to it in the current print
1072 chain, if one exists;
1073 (scm_port_with_print_state): New procedure: Associate a
1074 print-state with a port.
1075 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
1076 (scm_printer_apply): Wrap port and pstate as a smob;
1077 (print_state_printer): Removed.
1079 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
1081 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
1084 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
1085 testing (otherwise the port-print-state trick won't be transparent
1086 to the user; one example where this caused problems was in the
1087 (ice-9 format) module).
1089 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1091 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
1092 SCM_UNSPECIFIED instead of the set value.
1094 1999-08-20 James Blandy <jimb@mule.m17n.org>
1096 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
1098 * ports.h (enum scm_port_rw_active): New enum, containing
1099 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
1100 zero). The debugger knows about enums, but doesn't know about
1102 (typedef scm_port): Declare rw_active member to be an enum
1104 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
1106 * ports.c (scm_add_to_port_table): Same.
1107 * strports.c (st_flush, st_end_input): Same.
1109 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
1110 scm_must_realloc, and scm_done_malloc as appropriate.
1112 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1114 * sort.c (quicksort): Added condition to protect the algorithm
1115 from crashing the interpreter if the less predicate is buggy.
1117 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
1119 * fports.c (fport_write): fix line-buffering mode again.
1120 (scm_open_file): recognise 'l' for line-buffering.
1121 (scm_setvbuf): recognise _IOLBF for line-buffering.
1123 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1125 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
1128 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
1129 evaluating closures.
1131 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
1133 * fports.c (fport_write): use memcpy instead of strncpy, in case
1134 the data contains NUL.
1136 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1138 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
1140 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
1141 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
1142 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
1143 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
1144 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
1145 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
1146 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
1147 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
1148 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
1149 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
1150 scm_sym_ as prefix for symbols.
1152 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
1154 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
1155 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
1156 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
1157 scm_sym_atcall_cc): Made global.
1159 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1161 * eval.c (scm_sym_args): Made global.
1163 * objects.c (scm_set_object_procedure_x): Disallow setting of
1164 procedures for pure generic functions.
1166 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
1168 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
1169 Scheme name from lseek to seek, but lseek was added recently so
1170 it shouldn't be a big problem.
1171 * ports.c, gdbint.c, ioext.c: changed callers.
1173 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
1175 * fports.c (fport_input_waiting): if select is used, return 1
1176 instead of whatever FD_ISSET expands to. maybe it will be useful
1177 to interpret the value from the input_waiting ptob procedure as a
1178 lower bound on the number of bytes available.
1180 * Mikael asked for a few names to be changed...
1182 * ports.c (scm_make_port_type): take the write procedure as the
1183 second argument instead of the flush procedure.
1184 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
1185 fflush -> flush, read_flush -> end_input, fclose -> close,
1186 fill_buffer -> fill_input, ftruncate -> truncate,
1187 input_waiting_p -> input_waiting.
1189 * ports.c (end_input_void_port): was read_flush_void_port.
1190 (scm_set_port_end_input): was scm_set_port_flush_input.
1191 (scm_set_port_flush): was scm_set_port_write.
1192 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
1193 (scm_end_input): was scm_read_flush.
1194 (scm_fill_input): was scm_fill_buffer.
1195 (scm_flush): was scm_fflush.
1196 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
1197 (fport_end_input): was local_read_flush.
1198 (fport_flush): was local_fflush.
1199 (fport_close): was local_fclose.
1200 (fport_truncate): was local_ftruncate.
1201 (fport_seek): was local_seek.
1202 (fport_free): was local_free.
1203 (fport_fill_input): was fport_fill_buffer.
1204 * strports.c (st_end_input): was st_read_flush.
1205 (st_truncate): was st_ftruncate.
1206 * vports.c: (sf_flush): was sfflush.
1207 (sf_close): was sfclose.
1208 (sf_fill_input): was sf_fill_buffer.
1210 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
1213 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1215 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
1216 forms now contain the expressions to be dispatched upon instead of
1217 depending on a surrounding lambda or let; Generic function
1218 dispatch has been optimized; `apply' on a generic function now
1219 works a little bit strangely. It uses a trick so that the type
1220 dispatch code in SCM_CEVAL can be reused.
1222 * objects.h, objects.c (scm_apply_generic_env): Added (used by
1224 (scm_operator_p): Added.
1225 (scm_sym_atdispatch): Added.
1226 (scm_set_object_procedure_x): Modified to handle the new style
1228 (scm_object_procedures): New debugging procedure.
1230 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1232 * eval.c, eval.h (scm_sym_args): Added.
1234 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
1236 * feature.c, feature.h (scm_c_run_hook): Added.
1238 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
1239 cdrxnoap and loopnoap instead of begin and loop.
1241 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
1243 * ports.c (scm_putc, scm_puts),
1244 * unif.c (scm_uniform_array_write): use scm_lfwrite.
1245 * ports.c (scm_putc): change type of first argument from int to char.
1247 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1249 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
1250 SCM_IM_HASH_DISPATCH.
1252 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
1253 (scm_si_redfined, scm_si_hashsets): Moved.
1255 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
1256 flag which combines type and status info so that the class
1257 redefinition protocol has zero cost during normal execution.
1259 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
1261 * ports.h (scm_ptob_descriptor): include a write procedure again.
1262 it's more efficient for unbuffered fports (e.g., sockets.)
1264 * ports.c (scm_puts): use ptob->write.
1265 * vports.c (scm_make_sfptob): set write proc in ptob.
1266 * strports.c (scm_make_stptob): set write proc in ptob.
1267 * ports.c (write_void_port): new procedure.
1268 * vports.c (sf_write): new procedure.
1269 * ports.c (scm_lfwrite): use ptob->write.
1270 * strports.c (st_write): new procedure.
1271 * fports.c (fport_write): new procedure.
1272 (scm_make_fptob): set write in ptob to fport_write.
1273 * ports.h: prototype for scm_set_port_write.
1274 * ports.c (scm_make_port_type): initialise ptob write procedure.
1275 (scm_set_port_write): new proc.
1277 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
1279 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
1280 until we've verified that it is actually a port. (Thanks to
1283 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1285 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
1286 code, particularly an unnecessary test (len != size, where len ==
1287 size). (Was this leftovers from debugging code, or have I missed
1288 something profound?)
1290 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
1291 size. (Thanks to James Dean Palmer.)
1293 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
1294 (Thanks to Lorentey Karoly.)
1296 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1298 * eval.c (scm_m_expand_body): Use scm_cons_source.
1300 * struct.c (scm_print_struct): Use vtable name.
1302 * print.c (scm_init_print): Set name of print state type.
1304 * stacks.c (scm_init_stacks): Set name of stack type.
1306 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1308 * eval.c (SCM_CEVAL): Removed old implementation of internal
1311 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
1313 * debug.c, debug.h (scm_reverse_lookup): Added.
1314 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
1315 internal procedure definitions; Don't use scm_i_inner_name.
1317 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
1318 New isym operations.
1320 * eval.h: Added prototypes for multi language support functions.
1322 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
1323 improper lists in the low-level representation, since that will
1324 cause a begin to be prepended at macro expansion.
1326 * eval.c (scm_cons_source): Version of cons which copies source
1327 properties from an existing cell.
1328 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
1330 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
1331 procedure source before calling scm_unmemocopy instead of faking
1334 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1336 Ported `internal defines' fix from SCM. Original ChangeLog entry:
1338 1998-07-09 Radey Shouman <radey@colorage.com>
1340 * eval.c (ceval_1): Modifications to allow rewriting of interal
1341 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
1342 body of which it is the CAR is macro expanded by m_expand_body,
1343 which rewrites internal DEFINE.
1345 (m_expand_body): Added.
1347 (m_macroexp1): Added argument to control error checking:
1348 m_expand_body may speculatively expand forms in the wrong
1349 environments. Made argument number checks conditional on
1352 (m_body): Added, error checks bodies and inserts the ISYM tokens.
1354 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
1357 (m_cond): (m_case): (m_quote): Modified to avoid destructively
1358 changing their argument forms. Since m_expand_body
1359 speculatively macro expands forms the process must be
1362 (m_ident_eqp): Fixed to use proper environment.
1364 (renamed_ident): Added DEFER_INTS_EGC.
1366 Added prototypes for static functions.
1372 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
1373 is false, do not produce an error for unbound variables, return a
1374 pointer to cell_undef instead.
1376 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
1380 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
1381 destructively changing their argument forms. Since m_expand_body
1382 speculatively macro expands forms the process must be reversible.
1384 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
1385 SCM_IM_LET introduced by named lets.
1387 (scm_m_letstar): Use scm_m_body instead of bodycheck.
1389 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
1390 scm_letrec. scm_letrec1 does not check for a null binding and
1391 takes an additional argument to specify the ISYM of the body. Use
1392 scm_m_body instead of bodycheck.
1394 (scm_m_let): Use scm_m_body instead of bodycheck.
1396 (scm_m_expand_body, scm_macroexp): New.
1398 (unmemocopy): Account for ISYMs introduced by scm_m_body.
1400 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
1401 check=1. Throw error for internal defined that have not been
1402 rewritten by scm_m_expand_body.
1404 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
1405 Removed prototype for SCM_APPLY.
1407 * tags.h: Added extern declaration of scm_isymnames.
1409 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1411 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
1413 * lang.c: New file: Beginning of multi-language support.
1415 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
1417 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
1418 (scm_dynamic_wind): Added argument checking for the after guard so
1419 that we don't add garbage on the dynwind chain.
1420 (scm_swap_bindings): Added.
1422 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
1423 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
1424 (scm_isymnames): New isyms for multi-language support.
1426 * eval.c (scm_nil, scm_t): New symbols.
1427 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
1428 forms for multi-language support.
1430 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1432 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
1434 Renamed functions in the random function library interface
1435 from scm_i_XXX --> scm_c_XXX.
1437 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
1439 * ports.c (scm_putc): fix line-buffering.
1441 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1443 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
1444 scm_set_ptob_XXX --> scm_set_port_XXX.
1446 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1448 * ports.c, ports.h (scm_make_port_type): New interface for
1449 creation of port types (replaces scm_newptob). Just as for the
1450 smobs, we need to separate the internal representation of smob
1451 types from the interface, so that we easily can add new fields and
1452 rearrange things without caring about backward compatibility.
1453 This change was forced by the need in GOOPS to create classes
1454 representing port types.
1455 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
1456 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
1457 scm_set_ptob_seek, scm_set_ptob_truncate,
1458 scm_set_ptob_input_waiting_p): New setters.
1459 (scm_newptob): Rewritten to use scm_make_port_type. For backward
1461 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
1462 (scm_prinport): Removed.
1463 (scm_port_print): Added.
1464 (scm_print_port_mode): Added.
1465 (void_port_ptob, print_void_port, close_void_port, noop0):
1466 Removed. Removed #include "genio.h" Added #include "objects.h",
1469 * fports.c (prinfport): Moved code from ports.c.
1470 (local_free): Added.
1471 (scm_fptob): Removed. Instead use new interface.
1472 (scm_make_fptob): Added. (Need to create basic ports in a
1473 specific order in ports.c.)
1475 * strports.c (scm_stptob, prinstpt, noop0): Removed
1476 (scm_make_stptob): Added.
1478 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
1479 (scm_make_sfport): Added.
1481 * filesys.c (scm_dir_print): Don't use the port printing code.
1482 Instead provide specific directory printer.
1484 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
1486 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
1487 scm_ptob_descriptor.
1489 * smob.c (scm_smob_print): Handle non-existing type name nicely.
1490 Removed #include "genio.h"
1492 * objects.c (scm_make_port_classes): New function ptr.
1494 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
1496 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
1498 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
1499 allow the 1st argument to be a fdes or filename as well as a
1500 port (as in the filesys.c version).
1502 * filesys.c (scm_truncate_file): removed.
1504 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1506 * readline.c, readline.h: Removed.
1508 * objects.c, objects.h (scm_port_class): Added.
1509 (scm_class_of): Look up port class in scm_port_class.
1510 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
1511 SCM_INOUT_PCLASS_INDEX): Added.
1514 * Makefile.am: Removed genio.c, genio.x.
1518 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1520 * init.c: Make sure that scm_post_boot_init_modules is called only
1521 once. (Important when using a dumped image.; Thanks to Bernard
1524 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
1526 * guardians.c (scm_guardian_zombify): Separate scanning for
1527 zombies from marking the pairs of the free list.
1529 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
1530 use the macros. (Thanks to Michael Livshin.)
1532 * eval.c (scm_m_lambda): Let bodycheck check the body of the
1533 lambda. Let your sins be purified by the blood of the lambda.
1534 (Thanks to Eric Hanchrow.)
1536 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
1537 (Thanks to Valdis Kletnieks.)
1539 Fixes for EMX from Mikael Ståldal.
1541 * filesys.c: #include <io.h>, if we have it.
1542 * scmconfig.h.in: Regenerated.
1544 * stime.c (ftime): Delete declaration for this function --- let
1545 the system supply it.
1547 Cleanups from John Bley.
1549 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
1551 * gsubr.c: Don't include "gsubr.h" twice.
1553 Cleanups for compilation on Irix 6, from David Kaelbling.
1555 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
1556 regex_t pointer. This is what the callers have, mostly.
1557 (scm_regexp_exec): Don't forget to pass the `rx' argument to
1558 scm_regexp_error_msg.
1560 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
1561 int. That way, if we get a warning on this line, it's more likely
1562 that we're really missing bits we care about.
1564 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
1567 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
1568 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
1569 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
1570 cast at all is more appropriate in every case. At the moment, we
1571 assume everywhere that SCM is an integral type anyway.
1573 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
1575 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
1576 read_pos after scm_fill_buffer.
1578 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
1581 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
1582 fports.c (fport_fill_buffer): implement the interface change.
1584 * ports.c (scm_fill_buffer): interface change: no longer increments
1585 read_pos past the character that's returned. it seems clearer to
1586 leave it to the caller to decide what to do (thanks Jim).
1588 * vports.c (sf_fill_buffer): put the read char into the buffer
1589 as well as returning it.

1603 * strports.c (st_seek): change the resize checks.
1605 * ports.c (scm_ftruncate): throw error if offset works out negative.
1607 * strports.c (st_flush): increase string size in blocks of

1609 it's greater and reset read_buf_size.
1610 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
1611 to be maintained for output ports too (it holds the written
1612 part of the string, while write_buf may have unwritten buffer
1614 (st_truncate): rewritten.
1615 (top of file): added a few notes.
1617 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
1619 Patch from Greg Badros:
1620 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
1621 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
1622 (function pointer) argument to scm_make_gsubr and scm_make_subr
1623 calls. This avoids warnings in C++ programs using guile-snarf.
1625 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
1627 * strports.c (st_grow_port): set pt->read_pos. set
1628 pt->read_buf_size one less than pt->write_buf_size if there's
1629 an unwritten char at the end of the string. similarly for
1631 (st_resize_port): renamed from st_grow_port.
1632 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
1633 seek from read_end instead of write_end for SEEK_END.
1634 (st_ftruncate): calculate current length using readbuf, not write
1636 (scm_strport_to_string): use read_buf_size for length.
1637 (stfill_buffer): don't re-initialise the readbuf.

1653 use scm_make_smob_type_mfpe to initialize "free", "flo", "bigpos",
1654 and "bigneg" smob types.
1656 * smob.h: Add do ... while(0) idiom to SCM_NEWSMOB. Added
1657 SCM_RETURN_NEWSMOB macro. Added protos for new functions in
1660 * *.c: Use scm_make_smob_type_mfpe, instead of scm_newsmob, and
1661 use SCM_NEWSMOB or SCM_RETURN_NEWSMOB in constructors instead of
1662 SCM_NEWCELL and setting the CAR/CDR by hand.

1749 1999-06-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1751 * struct.c, struct.h:
1753 In order to support different kinds of deallocation, a destructor
1754 slot has been added to struct vtables. This allows for structs
1755 containing pointers to other memory blocks.

1828 Patch from Greg Harvey:
1829 * eq.c, eval.c, list.c, ramap.c, vectors.c: Always write parens
1830 around the condition of an `if', `while', etc., even if the
1831 condition is a macro invocation that expands to something
1832 surrounded by parens. It's more readable.
1834 * eval.c (scm_map, scm_for_each): Verify that all arguments are
1835 proper lists, and of the appropriate lengths.
1836 (check_map_args): New function. (Thanks to Greg Harvey for the
1839 1999-06-19 Michael Livshin <mike@olan.com>

1876 (scm_weak_size, scm_n_weak): Deleted.
1877 (scm_igc): Use SCM_WVECT_GC_CHAIN to build up a chain of weak
1878 vectors without allocating new storage during GC, using
1879 scm_weak_vectors as the head of the chain.
1880 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
1881 instead of stepping through an array.
1882 (scm_gc_sweep): Update offset used to find start of weak vector to
1884 (scm_init_storage): Set scm_weak_vectors to EOL.
1886 Fix from Ken Raeburn <raeburn@raeburn.org>:
1887 * gc.c (already_in_gc): New variable.
1888 (scm_igc): Set and clear already_in_gc; abort if it's set at
1891 1999-06-14 Jim Blandy <jimb@savonarola.red-bean.com>
1893 Fix from Gary Houston:
1894 * fports.c (local_seek): Signal an error if the seek fails.
1895 * ports.c (scm_lseek): Don't check return value of port's seek
1896 function; it's its job to signal an error if there's a problem.
1898 1999-06-12 Jim Blandy <jimb@savonarola.red-bean.com>
1900 * strports.c (scm_call_with_output_string): Don't include the

1906 scmsigs.c, strports.c, vports.c: Install the sources which
1907 actually correspond to the changes described below. I got the
1908 ChangeLog entries and the patch from two different places...
1910 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
1912 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
1913 it shows up as terrible performance, as we GC constantly.
1915 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
1916 newline. A bit faster, and definitely hairier.
1917 (scm_read_line): Count newlines here instead.
1919 * strings.c (scm_take_str): New function.
1920 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h
1921 (scm_take_str): New declaration. * ioext.c (scm_read_line): Use
1922 scm_take_str, to avoid copying the string.
1924 Add some simple-minded support for line buffered ports.
1925 * ports.h (SCM_BUFLINE): New flag for ports.
1926 * init.c (scm_init_standard_ports): Request line-buffering on
1927 the standard output port.
1928 * ports.c (scm_mode_bits): Recognize 'l' as a request for line
1930 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
1931 and there's a newline to be written, flush the port.
1933 Gary Houston's open-buffer port patches:
1935 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
1937 * ports.c: (scm_lseek): clear buffers even if just reading current

1948 strports.c (scm_mkstrport): check that pos is reasonable.
1949 ioext.c (scm_ftell, scm_fseek): use lseek.
1950 (SCM_CLEAR_BUFFERS): macro deleted.

1958 fports.h (scm_port): change size types from int to off_t.
1959 ports.c (scm_init_ports): initialise the seek symbols here
1960 instead of in ioext.c.
1961 strports.c (scm_call_with_output_string): start with an empty
1962 string, so seek and ftruncate can be used.
1964 gdbint.c: adjust string port usage.
1966 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
1968 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
1969 equivalent to fflush for the read buffer.
1970 * ports.c (scm_newptob): set read_flush.
1971 ports.c (void_port_ptob): set read_flush.
1972 fports.c (local_read_flush): new proc. add to ptob.
1973 strport.c (st_read_flush): likewise.
1974 vport.c (sf_read_flush): likewise.

1976 left but fdes. leaving it as a struct to allow for future changes.
1977 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
1978 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
1979 ptob proc if the read buffer is filled.
1981 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
1983 * ports.h (scm_port): add a rw_random member and replace
1984 reading and writing members with rw_active member.
1985 SCM_PORT_READ/SCM_PORT_WRITE: new values.
1987 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
1989 * ports.h (struct scm_port_table): add writing and reading members
1990 to replace write_needs_seek: it isn't good enough for non-fports.
1991 ports.c, ioext.c, fports.c: corresponding changes.
1992 (struct scm_port_table): give it a typedef and rename to scm_port.
1993 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
1994 corresponding changes.
1996 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
1998 * ports.c (scm_newptob): bugfix: set seek member.

2000 and generalised to all port types.
2002 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
2004 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
2005 signals (it was only being done for handlers installed from Scheme).
2006 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
2007 waiting for input caused an EINTR error from read.
2009 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
2011 * ports.h (struct scm_port_table): make all the char members
2012 unsigned, so they convert to int without becoming negative if large.
2014 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
2016 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
2017 with threads enabled. rename this procedure to
2018 fport_wait_for_input and take a port instead of a fdes.
2019 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
2021 * readline.c (scm_readline): Applied a patch from Greg Harvey to
2022 get readline support working again: use fdopen to get FILE objects.
2024 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
2026 * gc.c (scm_init_storage): install an atexit proc to flush the
2028 (cleanup): the new proc. it sets a global variable which can be
2029 checked by the ptob flush procs to avoid trying to throw
2030 exceptions during exit. not very pleasant but it seems more reliable.
2031 * fports.c (local_fflush): check terminating variable and if set
2032 don't throw exception.
2033 * CHECKME: that the atexit proc is installed if unexec used.
2035 * throw.c (scm_handle_by_message): don't flush all ports here.
2036 it still causes bus errors.
2038 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
2039 and move to ioext.c.
2041 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
2043 * ports.c (scm_char_ready_p): check the port buffer and call the
2044 ptob entry if needed.
2046 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
2047 ptob initialisers. use it in char-ready
2049 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
2051 * vports.c (sfflush): modified to write a char (since softports
2052 currently use shortbuf.)
2054 * fports.c (scm_standard_stream_to_port): moved to init.c and
2057 * init.c (scm_init_standard_ports): make stdout and stderr
2058 unbuffered if connected to a terminal. with stdio they
2059 were line-buffered by default.
2061 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
2064 * ports.h (scm_ptobfuns): change fflush return to void.
2065 change flush proc definitions.
2067 * strports.c (scm_call_with_output_string): get size from
2068 buffer instead of port stream.
2069 (st_flush): new proc.
2071 * ports.h (struct scm_port_table): added write_end member,
2072 as an optimisation. set it where write_buf_size is set.
2074 * ports.h (struct scm_port_table): change stream from void *
2075 back to SCM. SCM presumably must be large enough to hold a
2076 pointer (and probably vice versa but who knows.)
2077 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
2079 (scm_puts): rewritten
2080 * fports.c (local_ffwrite, local_fputs): removed.
2081 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)
2082 * vports.c (sfputc, sfputs, sfwrite) likewise.
2083 * ports.c (write_void_port, puts_void_port): removed.
2084 (putc_void_port, getc_void_port, fgets_void_port): likewise.
2086 * ports.c (scm_lfwrite): rewritten using fport.c version.
2088 * fports.c (local_fputc): deleted.
2090 * ports.c (scm_add_to_port_table): initialise write_needs_seek.
2092 * ports.h (scm_ptobfuns): add seek function pointer.

2449 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2451 Most of this batch of changes is about how to deal with extended
2452 types when an object system is loaded into Guile. A nice object
2453 system is capable of representing Guile's types as class objects.
2455 For example, we want a regular expression to be of class <regex>.
2456 But regular expressions are smobs which aren't under direct
2457 control of the object system, so there has to be some mechanism
2458 which informs the object system that a new class should be created
2459 which can represent the smob type. I call this a "wrapper class".
2461 * objects.c: #include "smob.h";
2462 (scm_class_keyword): Removed. (Class is automatically created by
2464 (scm_smob_class): Array of smob classes indexed by smobnum.
2465 (scm_make_extended_class): "Plugin" function pointer for creation
2466 of wrapper classes for smob and struct types.
2467 (scm_class_of): Handle compiled closures. (Currently regarded as
2469 Use scm_smob_class to handle smob types;
2470 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
2471 through scm_smob_class;
2474 * smob.c (scm_newsmob): Also create a wrapper class if
2475 scm_smob_class has been initialized.
2477 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
2478 type code and smobnum.
2480 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
2481 (scm_struct_table): Weak key table with auxilliary information for
2482 struct types. Currently used for names and wrapper classes.
2483 (scm_struct_ihashq): Hash function for structs.
2484 (scm_struct_create_handle): Get/create entry in scm_struct_table.
2485 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
2486 for accessing names of vtables. The record implementation in
2487 boot-9.scm currently uses the setter to record the name of record
2488 types. When the object system is initialized, it can use this
2489 information to create wrapper classes with suitable names.
2490 (scm_init_struct): Allocate scm_struct_table.
2491 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
2492 (struct tags are a finite resource and we might want to restrict
2493 the use of tags to vtables only. E.g., Goops only uses tags for
2495 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
2497 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
2500 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
2501 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
2502 Used for access of struct table entries.
2504 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
2505 (scm_hash_fold): New procedure. Used to process all entries in a
2506 hash table (in no particular order).
2508 Argh! For the umpteenth time I got compilation errors because of
2509 the "intuitive" name `kw'. This has to have an end:
2511 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
2512 "kw" --> "keywords" everywhere.
2513 (I doubt that this will cause big compatibility problems since the
2514 application interface is unaffected.)
2516 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
2518 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>

2521 column inums to native form.

2536 Extract the lookup closure from an environment.

2543 * debug.c (scm_procedure_name): Use name property in the default
2546 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
2548 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
2550 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
2551 procedure throughout.
2553 * print.c (scm_iprin1): Removed extraneous space when printing
2554 procedure-with-setters.
2556 Entity and operator setter slots were introduced as a complement
2557 to the <procedure-with-setter> type in order to support entities
2558 and operators with setters in a reasonable and efficient way.
2559 * procs.c (scm_procedure, scm_setter): Handle entity and operator

2575 directly through the instance.
2577 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
2579 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
2580 scm_struct_i_flags instead of scm_vtable_index_layout!
2582 * list.c (scm_list_star): New procedure.
2584 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

2606 * readline.c (in_readline, reentry_barrier_mutex): Make these
2609 * readline.c: #include <sys/time.h> and "iselect.h", so we can
2610 control how long we're paused, and threads will run while we're
2612 (match_paren, find_matching_paren, init_bouncing_parens): New
2614 (scm_init_readline): Call init_bouncing_parens.
2615 (scm_readline_opts): Add the bounce-parens option.
2616 * readline.h (SCM_READLINE_BOUNCE_PARENS): New readline option.
2617 (SCM_N_READLINE_OPTIONS): Adjust.

2664 sysdep_dynl_unlink, sysdep_dynl_func): Arguments FNAME, SUBR, and
2665 SYMB now point to const.
2667 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2669 * print.c (scm_iprin1): Use scm_procedure_name instead of
2670 scm_procedure_property for compiled closures.
2672 * tags.h (scm_tc7_pws): New procedure type. Four representations
2673 for procedure-with-setters were considered before selecting this
2676 1. A closure where the CODE and ENV slots are used to represent
2677 the getter and a new SETTER slot is used for the setter. The
2678 original getter is stored as a `getter' procedure property. For
2679 closure getters, the CODE and ENV slots contains a copy of the
2680 getter's CODE and ENV slots. For subr getters, the CODE contains
2683 2. A compiled closure with a call to the getter in the cclo
2684 procedure. The getter and setter are stored in slots 1 and 2.
2686 3. An entity (i.e. a struct with an associated procedure) with a
2687 call to the getter in the entity procedure and the setter stored
2688 in slot 0. The original getter is stored in slot 1.
2690 4. A new primitive procedure type supported in the evaluator. The
2691 getter and setter are stored in a GETTER and SETTER slot. A call
2692 to this procedure type results in a retrieval of the getter and a
2693 jump back to the correct eval dispatcher.
2695 Representation 4 was selected because of efficiency and
2698 Rep 1 has the advantage that there is zero penalty for closure
2699 getters, but primitive getters will get considerable overhead
2700 because the procedure-with-getter will be a closure which calls
2703 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
2704 <procedure-with-setter>, but together with rep 2 it suffers from a
2705 three level dispatch for non-GOOPS getters:
2707 cclo/struct --> dispatch proc --> getter
2709 This is because the dispatch procedure must take an extra initial
2710 argument (cclo for rep 2, struct for rep 3).
2712 Rep 4 has the single disadvantage that it uses up one tc7 type
2713 code, but the plan for uniform vectors will very likely free tc7
2714 codes, so this is probably no big problem. Also note that the
2715 GETTER and SETTER slots can live directly on the heap, using the
2716 new four-word cells.
2718 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,
2719 SCM_SETTER): New macros.

2732 entry for scm_tc7_pws.
2734 * procs.c (scm_procedure_p): Added case label for scm_tc7_pws.

2789 function call are executed in a well defined order.
2791 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
2793 * alloca.c (alloca): Cast value returned by malloc. (Thanks to

2798 * random.c: Removed alloca includes.
2800 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
2802 * Makefile.in: This changed, for some reason I don't really
2803 understand, when I ran automake in the top level directory. This
2804 may be contamination by Cygnus internal releases. If you re-run
2805 automake and this change gets reverted, don't worry about it.

2823 Interface same as slib's.
2825 * Makefile.am: Added random.c, random.h, random.x.
2827 * init.c: #include "random.h";

2834 * guardians.c, guardians.h (scm_make_guardian,
2835 scm_guardian_gc_init, scm_guardian_zombify, scm_guard,
2836 scm_get_one_zombie, scm_init_guardian): This is an implementation
2837 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
2838 David Eby (1993) "Guardians in a Generation-Based Garbage
2839 Collector" ACM SIGPLAN Conference on Programming Language Design
2840 and Implementation, June 1993 ftp://ftp.cs.indiana.edu
2841 /pub/scheme-repository/doc/pubs/guardians.ps.gz

2851 1998-12-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2853 * macros.c (scm_makacro, scm_makmacro, scm_makmmacro): Added
2856 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2858 Move the procedure slots of entities to invisible slots (so that
2859 we can have operator class objects which themselves are entities).
2860 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
2861 SCM_STRUCTF_ENTITY): New constants.
2863 * struct.c (scm_make_struct): Allocate "invisible" room for
2864 procedures if SCM_STRUCTF_ENTITY is set in vtable.

2873 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0,
2874 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
2876 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
2878 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
2879 of syntactic forms, similar to SCM_PROC.
2880 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
2881 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
2882 for the name symbols when needed.
2884 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
2886 * Makefile.in: Regenerated.
2888 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
2890 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
2891 take the address of _into; it might be a register. Just have
2892 scm_debug_newcell return the new cell.
2893 * gc.c (scm_debug_newcell): Just return the new cell, instead of
2894 taking the address of a place to store it as an argument.
2895 * gc.h (scm_debug_newcell): Change declaration.
2896 (Thanks to Greg Harvey.)
2898 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

2911 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2913 * backtrace.c (display_frame): Made more robust. Doesn't throw an
2914 error if no source properties can be found for a frame. (Thanks
2915 to Christian Lynbech.)
2917 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2919 * objects.h: Removed slots direct_supers and direct_slots from the
2920 definitions of the rudimentary classes described by objects.h.
2922 * objects.c, objects.h (scm_entity_p): New procedure. Together
2923 with the predicates scm_procedure_p and scm_struct_p, this
2924 predicate makes it possible to differ between structs, entities
2927 * modules.c, modules.h (scm_resolve_module): New function.
2929 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2931 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
2932 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
2935 * objects.c (scm_entity_p): New procedure.
2937 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
2938 for asubrs, rpsubrs, lsubrs and lsubr_2s.
2940 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2942 * procprop.h (scm_i_procedure_arity): Added declaration.
2944 * procprop.c (scm_i_procedure_arity): Made global; New code to
2945 handle operators and entities.
2946 (scm_procedure_property): No need to call scm_procedure_p since
2947 scm_i_procedure_arity now does all necessary type checking.
2948 Added #include "objects.h".
2950 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
2951 s_add_hook_x --> s_remove_hook_x.
2952 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.

2955 * feature.c, feature.h (scm_reset_hook_x): New procedure.
2956 (scm_make_hook): Optional argument defines number of arguments to
2958 (scm_make_named_hook): Take number of args as second arg.
2959 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
2960 boot-9.scm for a while); First arg is the hook. The rest are
2961 arguments passed on to the hook procedures.
2963 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
2965 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
2966 scm_logbit_p): Do the computation in ulongs. This is not as nice
2967 as doing it in bignums, but at least it's good enough for
2968 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
2970 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
2971 subexpressions. (Thanks to Charbel Jacquin.)
2973 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
2975 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
2976 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
2977 (scm_make_named_hook): New function.
2979 * feature.c: Added #include "eval.h".
2981 * modules.c (scm_make_module): Beautify the module.
2983 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2985 * modules.c, modules.h: New files: C interface to modules. (This
2986 is necessary in order to interface the object system to Guile
2987 properly. The guts of these modules will be replaced by the new
2988 module system in the future.)
2990 * init.c: Added #include "modules.h"
2991 (scm_boot_guile_1): Call scm_init_modules.
2992 (invoke_main_func): Call scm_post_boot_init_modules.
2994 * Makefile.am: Added modules.c, modules.x, modules.h.
2996 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
2998 * procs.c: #include "objects.h"
2999 (scm_procedure_p): Return #t also on structs which are operators.
3001 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
3002 <operator-metaclass> and <entity-class> to <standard-class>,
3003 <operator-class> and <entity> in order to conform with STKlos
3006 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
3007 which isn't an operator.
3008 (SCM_APPLY): Ditto, but jump to badproc.
3010 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
3012 * eval.c (SCM_CEVAL): Allow structs implanted in code.
3013 Previously, structs implanted in code were interpreted as forms
3014 the operator of which was a gloc. We solve this by checking for
3015 the zero in the emulated vcell in the struct vtable. Since
3016 implanted structs always will look like forms with a gloc
3017 operator, execution will only be slowed down by maximally one
3018 extra test-and-branch per application.
3020 * evalext.c (scm_definedp): Removed check for isyms; Added a
3021 second optional argument: It is now possible to supply an
3022 evaluation environment in which to look for the symbol.
3024 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3026 * readline.c (scm_init_readline): Set
3027 rl_basic_word_break_characters. (Thanks to Ian Grant.)
3029 * coop.c (coop_condition_variable_wait): Removed
3030 (coop_condition_variable_wait_mutex): Folded logic of
3031 coop_mutex_unlock into coop_condition_variable_wait_mutex to
3032 prevent condvar signal lossage. Previously, another thread could
3033 start to run after unlocking the mutex but before putting the
3034 current thread on the wait queue. If that thread then would
3035 signal the first, the signal would be lost. (Thanks to Christian
3038 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3040 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
3043 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3045 * objects.c (scm_i_make_class_object): Renamed from
3046 make_class_object; exported; error checking moved to
3047 scm_make_class_object and scm_make_subclass_object.
3048 (scm_make_class_object, scm_make_subclass_object): Use
3049 scm_i_make_class_object.
3050 (scm_make_subclass_object): Let the subclass have same metaclass
3053 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3055 * debug.c (scm_debug_options): Bugfix: Set the value of
3056 scm_stack_checking_enabled_p after setting debug options;
3057 #include "stackchk.h". (Thanks to Richard Polton.)
3059 1998-11-13 Radey Shouman <rshouman@metro2000.com>
3061 * unif.c (scm_array_contents): removed unnecessary test for 0
3064 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3066 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
3067 Replaced by macro `collect' in boot-9.scm.
3069 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3071 * eval.c (scm_copy_tree): Copy source properties if existent.
3073 * debug.c (scm_start_stack): Copy source when evaluating. (If we
3074 don't, we may end up passing memoized source to a transformer.)
3076 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3078 * stack.c (get_applybody): Help function which lookups the first
3079 body form of the apply closure.
3080 (read_frames): Prevent the source of the first form of the apply
3081 closure from being recorded. This would only be confusing.
3083 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
3084 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
3086 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
3088 * stacks.c (read_frame): Bugfix: Removed lingering `else'
3090 (read_frames): Use SCM_MACROEXPP.
3092 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3094 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
3095 don't contain interesting information since all arguments are
3096 present in the frame which applies the compiled closure anyway.);
3097 Skip the transformer application frames.
3099 * print.c (scm_iprin1): Print gsubrs as primitives.
3101 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3103 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
3105 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
3106 that we can identify these in a backtrace. (This change doesn't
3107 introduce any significant speed penalty.)
3109 * eval.c: Added note about `serial-map' using scm_map.
3111 * read.c, read.h (scm_read_options, scm_read_opts): Removed
3112 readline options. They should reside in their own options array.
3114 * readline.c, readline.h (scm_readline_options,
3115 scm_readline_opts): Moved readline options here.
3117 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3119 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
3120 SCM_ROCHARS instead of SCM_CHARS.
3122 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
3123 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
3125 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3127 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
3128 This is quite important since the latter clears the
3129 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
3130 every single character read...
3132 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3134 * print.c (scm_iprin1): Removed suspect looking (and indeed
3135 malevolent) semicolon after test for user supplied closure print
3136 procedure. (Thanks to Telford Tendys.)
3138 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
3139 (scm_memq, scm_memv, scm_member): Do argument checking *before*
3140 starting to search the list. Removed call to sloppy_mem_check.
3142 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
3143 procedures: Same as scm_delq_x et al, but delete maximally one
3146 * options.c (scm_options, scm_init_options): GC-protect option
3147 values of type SCM. (Thanks to Telford Tendys.)
3149 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3151 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
3152 make sure that there always is a "real" scm_lookupcar.
3154 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3156 * read.c, read.h (scm_read_opts): New read options
3157 "history-length" and "history-file".
3158 (scm_read_options): Stifle history to history length.
3160 * readline.c (scm_read_history, scm_write_history): New procedures.
3162 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3164 * eval.h (scm_macro_eval_x): Removed declaration.
3166 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
3167 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
3168 Renamed and made global.
3170 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
3171 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
3173 * evalext.c, evalext.h: New files. Contain non-R5RS things
3174 having to do with evaluation.
3176 * evalext.c (scm_serial_map): New procedure: Version of `map'
3177 which guarantees that the procedure is applied to the lists in
3179 (scm_m_sequence_to_list): New syntax: Version of `begin' which
3180 returns a list of the results of the body forms instead of the
3181 result of the last body form.
3182 (scm_definedp, scm_m_undefine): Moved from eval.c
3184 * evalext.h (scm_m_sequence_to_list): Added declaration.
3186 * macros.c, macros.h: New files.
3187 (scm_procedure_to_syntax, scm_procedure_to_macro,
3188 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
3189 scm_macro_name, scm_macro_transformer): Moved from eval.c
3190 (scm_make_synt): Moved from eval.c
3192 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
3194 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
3197 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
3199 * debug.c, print.c: Added #include "macros.h".
3201 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3203 This change adds the ability to use `unread-char' multiple times
3204 without interspersed reads and adds the new procedure
3205 `unread-string'. The change is optimized for the common case of
3206 unreading a single character. This is also the reason behind the
3207 choice to store characters in the port itself: in most cases no
3208 extra malloc is required.
3210 The amount of code in some macros in ports.h has been increased to
3211 the extent that they would fit better as C functions, but, since
3212 this code belongs to the port representation, such functions
3213 should be placed in ports.c which would cause calls back and forth
3214 between ports.c and genio.c. That is not good for performance.
3215 Also, keeping them as macros allows the compiler to do some
3216 optimizations which are needed to make the current interface
3217 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
3219 One benchmark (Guile startup time) indicates an increase of
3220 loading speed of 1%. Another (reading (using `read') boot-9.scm
3221 10 times) shows no change in performance.
3223 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
3224 made to find a beautiful solution.)
3226 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
3227 (SCM_TRY_CLRDY): New macro: Only clear the first unread
3228 character. (SCM_CLRDY clears all.)
3229 (SCM_N_READY_CHARS): New macro: Returns number of unread
3230 characters in a port. Returns wrong answer if SCM_CRDYP is false.
3231 (struct scm_port_table): New fields: `entry' contains port table
3232 index, `cp' points to last unread char, `cbuf' is the buffer for
3233 unread chars, `cbufend' points after end of the character buffer.
3235 * ports.h, ports.c (scm_unread_string): New procedure.
3236 (scm_grow_port_cbuf): New function.
3238 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
3240 (scm_generic_fgets), fports.c (local_fgets): Use a loop
3241 to read unread characters. Use SCM_TRY_CLRDY instead of
3244 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
3246 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
3248 * genio.c, genio.h (scm_ungets): New function.
3250 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
3253 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3255 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
3256 declarations. (Thanks to Russ McManus.)
3258 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3260 * numbers.c (num2long): As a software archeologist, I'm proud of
3261 this finding! :) Preliminary dating suggests an almost 4 year old
3262 remnant from the SCM ancestor. The sample has been removed from
3263 the finding site and is now safely stored in the repository.
3265 * numbers.h: Removed prototype for num2long.
3267 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
3269 * gh_data.c (gh_scm2doubles): Make it possible to pass result
3270 array as second arg.
3271 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
3272 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
3273 * gh.h: Updated and added prototypes.
3275 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
3277 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
3279 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
3281 * guile-snarf.in: Never generate an empty file. (Thanks to
3284 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
3285 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
3286 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
3287 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
3288 gh_new_procedure5_0): Specify argument types, to appease C++
3289 compilers. (Thanks to Brad Bowman.)
3291 Bug reports from Russ McManus:
3292 * guile-snarf.in: If the CPP environment variable is set, use that
3293 as the C preprocessor, instead of the preprocessor autoconf
3295 * snarf.h (SCM_PROC): Cast the function pointer passed to
3296 scm_make_gsubr, to satisfy C++.
3298 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
3299 Use the handler passed, instead of ignoring it and using
3300 gh_standard_handler. (Thanks to Etienne Bernard.)
3302 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
3304 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
3307 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>

3324 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
3327 * script.c (scm_compile_shell_switches): Define
3328 use-emacs-interface in the root module, so the repl code can see
3329 it. See today's change to top-repl in ice-9/boot-9.scm.
3331 * filesys.c (set_element, get_element): Make sure that `element'
3332 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
3333 Boekemeier and Jorgen "forcer" Schaefer.)
3335 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
3337 * chars.c (scm_charnames): In ASCII character name table, make
3338 newlines print as #\newline by default, not #\nl.
3340 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
3341 alphabetical order. Oh thrills. But it helps me know how far
3342 along in the compilation I am.
3343 * Makefile.in: Regenerated.
3345 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3347 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
3348 #bytes(...) to #y(...), and syntax for short vectors from
3349 #short(...) to #h(...). This may seem nutty, but, like the other
3350 uniform vectors, byte vectors and short vectors want to have the
3351 same print and read syntax (and, more basic, want to have read
3352 syntax!). Changing the read syntax to use multiple characters
3353 after the hash sign breaks with the conventions used in R5RS and
3354 the conventions used for the other uniform vectors. It also
3355 introduces complexity in the current reader, both on the C and
3356 Scheme levels. (The Right solution is probably to change the
3357 syntax and prototypes for uniform vectors entirely.)
3359 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
3361 Don't use local_fgets on sockets; ftell doesn't work on sockets.
3362 (Thanks to Jorgen "forcer" Schaefer.)
3363 * ports.h (SCM_NOFTELL): New flag.
3364 * fports.c (local_fgets): If it's set, use the generic fgets.
3365 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
3367 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3369 * script.c (scm_compile_shell_switches): Add handling of -q switch
3370 (inhibit loading of user init file).
3371 (scm_shell_usage): Add usage text for -q switch.
3372 (scm_compile_shell_switches): Always load user init file first if
3373 it is loaded at all.
3375 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
3377 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
3378 and is now broken under NetBSD. I can't fathom what it's trying
3379 to do, so I've replaced it with something that I do understand,
3380 which seems to work, and which isn't broken on NetBSD. "Progress?
3381 You Decide." (Thanks to Perry Metzger.)
3383 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
3384 signed/unsigned comparison.
3386 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
3388 Warning fixes from Greg Harvey:
3389 * unif.c (scm_array_set_x): initializer for pos
3390 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
3391 * struct.c (scm_struct_ref, scm_struct_set_x): Added
3392 initializers for field_type, since EGCS so desparately wants to
3394 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
3395 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
3396 when GUILE_DEBUG is defined.
3397 * dynwind.h (scm_wind_chain): Same.
3398 * ports.h (scm_pt_size, scm_pt_member): Same.
3399 * print.h (scm_current_pstate): Same.
3400 * procs.h (scm_make_cclo): Same.
3402 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
3404 Handle short and long long uniform arrays properly. (Thanks to
3406 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
3407 raeql_1): Add cases for scm_tc7_svect (short vectors) and
3408 scm_tc7_llvect (long long vectors).
3410 Change the way libguile and boot-9.scm are timestamped, to try to
3411 get rid of these spurious mismatch warnings. Now both
3412 libguile/versiondat.h and ice-9/version.scm are generated directly
3413 by the configuration process, rather than having version.scm
3414 generated directly, and libguile/versiondat.h generated by the
3415 Makefile, which is generated by configure. It seems that
3416 sometimes the Makefile would change, but versiondat.h depends on
3417 Makefile.in, not Makefile, so it wouldn't get rebuilt.
3418 * Makefile.am (versiondat.h): Target removed; this is generated
3419 directly by the configure script now.
3420 (BUILT_SOURCES): Remove versiondat.h.
3421 * versiondat.h.in: New file, transformed by the configure script
3423 * Makefile.in: Regenerated.
3425 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
3426 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
3427 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
3428 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
3429 if we want to use them in a header file some day, we can. (Thanks
3430 to Michael Livshin.)
3432 * stime.c (scm_get_internal_real_time): Do the arithmetic using
3433 SCM numbers, so we won't have rollover problems; the range of a
3434 signed long in milliseconds is about 25 days. (Thanks to Karl
3437 Don't redefine sleep and usleep; fix this problem now.
3438 * coop.c (sleep, usleep): Remove declarations; we don't use or
3439 redefine these any more.
3440 (scm_thread_usleep, scm_thread_sleep): New functions which do the
3441 job of usleep and sleep in a thread-friendly way. We can use
3442 these in the rest of Guile. Define versions for systems both with
3443 and without iselect.
3444 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
3445 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
3446 we're just using it, not redefining it, we can use a K&R style
3448 (sleep): Declare this, too, if the system hasn't.
3449 (scm_sleep, scm_usleep): Use scm_thread_sleep and
3450 scm_uthread_sleep if they're available; otherwise, just call the
3452 * scmconfig.h.in: Regenerated.
3454 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
3456 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
3458 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
3460 * threads.c: Doc fix.
3462 The argument type of usleep varies from system to system,
3463 as does the return type. We really shouldn't be redefining usleep
3464 at all, but I don't have time to clean that up before the 1.3.
3465 release. It's on the schedule for afterwards. (Thanks to Julian
3467 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
3469 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
3470 * scmconfig.h: Regenerated.
3472 * simpos.c (scm_software_type): Procedure deleted. This isn't the
3473 right way to handle system variation. Autoconf's approach is the
3475 * simpos.h (scm_software_type): Declaration deleted.
3477 * script.c (scm_find_executable): Don't test if unix is #defined
3478 here; first, NetBSD doesn't #define it, and second, it's the wrong
3479 way to go about these things. (Thanks to Perry Metzger.)
3480 (dld_find_executable): Delete this MSDOS support code. This isn't
3481 the way we want to support this; it needs to be rethunk at a
3484 * genio.c (scm_do_read_line): Don't just politely check that the
3485 line was either non-empty or EOF. Abort if it's empty and not
3488 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
3490 * scmconfig.h.in: Regenerated.
3492 * libguile.h: Don't omit the dynamic linking functions. (Thanks
3495 * genio.c (scm_do_read_line): Count lines correctly when the file
3496 doesn't end in a newline.
3498 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
3500 * genio.c (scm_do_read_line): Maintain the line count correctly.
3501 (Thanks to Harvey J. Stein and Greg Harvey.)
3503 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
3506 * numbers.c (big2str): Protect t from garbage collection until
3507 we're done. (Thanks to Gary Houston.)
3509 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
3511 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
3513 * Makefile.in: Regenerated.
3515 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
3516 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
3519 Do magic to mix reads and writes on stdio FILE-based ports.
3520 (Thanks to Christian Lynbech.)
3521 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
3523 (pre_read, pre_write): New functions.
3524 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
3525 local_fputs): Call them.
3526 (local_fflush): Mark the port as ready for reading and writing.
3527 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
3528 flags on new port objects. This might not be accurate --- who
3529 knows what state the FILE * is in when we get it --- but it won't
3530 do extraneous calls to fflush or fseek, so it's no worse than the
3531 behavior before this change.
3532 * ports.h: Add comment.
3534 Centralize the creation of port objects based on stdio FILE * in
3535 fports.c; don't just throw them together anywhere.
3536 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
3537 what the rest of Guile wants. Don't set the revealed count;
3538 that's only appropriate for stdin, stdout, stderr.
3539 (scm_standard_stream_to_port): This function does set the revealed
3541 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
3542 not scm_stdio_to_port.
3543 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
3544 * fports.c (scm_open_file): Same.
3545 * posix.c (scm_pipe): Same.
3546 * socket.c (scm_sock_fd_to_port): Same.
3547 * ioext.c (scm_fdopen): Same.
3548 (scm_freopen): Moved from here to...
3549 * fports.c (scm_freopen): ... here. This is really something that
3550 munges the internals of an fport, so it should go here.
3551 * fports.h (scm_stdio_to_port): Adjust prototype.
3552 (scm_standard_stream_to_port, scm_freopen): New protoypes.
3553 * ioext.h (scm_freopen): Prototype removed.
3555 * filesys.c (set_element, get_element): This can work on both pipe
3556 and file ports, so use SCM_FPORTP to typecheck, instead of testing
3559 * scmconfig.h.in: Regenerated.
3561 Change the definition of the functions in scm_ptobfuns so that
3562 they get passed the port object, not the port's stream.
3563 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
3564 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
3565 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
3566 Pass the port itself to the scm_ptobs function.
3567 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
3568 scm_generic_fgets): Same.
3569 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
3570 getc_void_port, fgets_void_port, close_void_port): Just change the
3571 argument names; these functions don't really do anything.
3572 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
3573 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
3574 port as an argument, and use SCM_STREAM to get the stdio FILE *.
3575 Also, use prototyped definitions, and get rid of the extra
3577 (scm_fptob, scm_pipob): We don't need casts here any more.
3578 * strports.c (prinstpt): Use prototype declarations.
3579 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
3580 and use SCM_STREAM to get the string info. Also, use prototyped
3581 definitions, and get rid of the extra declarations.
3582 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
3585 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
3586 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
3588 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
3589 scm_fgets, for consistency.
3590 (scm_fptop, scm_pipob): References updated.
3592 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
3594 Include the source location in error messages for scripts.
3595 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
3596 stack is still there when we catch the error.
3597 * throw.c (handler_message): If we are handling an error with a
3598 message, then put together the proper arguments and call
3599 scm_display_error, instead of scm_display_error_message. That
3600 displays source location, if it can find it.
3602 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
3604 * gc.c (scm_unprotect_object): Change this so that calls to
3605 scm_protect_object and scm_unprotect_object nest properly.
3606 (scm_protect_object): Doc fixes.
3608 * strings.c (scm_string_set_x): Require the argument to be a
3609 writable string, not a substring or a symbol.
3610 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
3611 (Thanks to John Redford and Charbel Jacquin.)
3613 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
3615 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
3617 * eval.c (safe_setjmp): Remove this misunderstanding.
3618 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
3621 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
3623 * libguile.h: Mark these as C declarations, for compilation by C++
3626 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
3627 __cplusplus clause. I seriously doubt this ever worked the way
3628 the author seems to have intended.
3630 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
3632 Utterly needless cleanups to hopelessly messy code.
3633 * ports.c: Doc fixes.
3634 (scm_fflush): Moved to ...
3635 * genio.c (scm_fflush): ... here, amongst all the other port
3636 method invocation functions.
3637 * genio.h, ports.h: The prototype moves too.
3639 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
3641 * backtrace.c (display_error_body): The current frame does not
3642 always have a parent frame; consider a function called directly
3643 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
3646 * alloca.c (alloca): Undo yesterday's changes, and simply call
3647 malloc directly for storage, and abort if we don't get what we
3648 want. The situation is much simpler --- just call malloc. Emacs
3649 has bizarre/evil requirements (signal handlers might malloc unless
3650 you set this global flag, so you have to set the flag around all
3651 calls to malloc) which we are certainly not going to conform to,
3652 so we can do the simple and obvious thing.
3654 * coop.c (coop_condition_variable_wait): Make this function
3655 static. It's only useful internally --- you should never just
3656 wait on a condition variable.
3657 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
3659 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3661 * unif.c (scm_array_set_x): Accept any kind of number as an
3662 element for a uniform vector of doubles. This is more consistent
3663 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
3665 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
3666 works; I can't conveniently test it myself. (Thanks to Dvid
3667 Tillman for the bug report.)
3669 * init.c: Doc fixes.
3671 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
3672 from here, not from scm_compile_shell_switches (which is a pretty
3673 dumb place to do it).
3674 (scm_load_startup_files): New function.
3675 (scm_ice_9_already_loaded): Variable moved to here from script.c.
3676 * script.c (scm_compile_shell_switches): Don't load the startup
3678 (scm_ice_9_already_loaded): Variable moved.
3679 * init.c (scm_load_startup_files): Prototype for new function.
3680 * gh_init.c (gh_enter): Doc fix.
3682 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3684 Some anti-warning changes from Greg Harvey.
3685 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
3686 warnings when it doesn't understand our NORETURN declarations in
3688 * posix.c (scm_mknod): Similar.
3690 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3692 * posix.c (scm_getpwuid): If we can't find an entry, return our
3693 own message, instead of using scm_syserror --- the getpwMUMBLE
3694 functions don't set `errno' to anything interesting.
3696 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3698 Get rid of warnings from the cooperative threading system.
3699 * threads.h (scm_single_thread_p, scm_yield,
3700 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
3701 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
3702 scm_wait_condition_variable, scm_signal_condition_variable): Add
3703 prototypes for these Scheme-visible functions.
3704 * coop-defs.h (coop_next_runnable_thread,
3705 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
3706 Prototypes for these here, even though they're from iselect.c.
3707 (coop_condition_variable_wait, coop_join): Add prototypes.
3708 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
3709 scm_threads_free_condvar): Make these smob functions static.
3710 * coop-threads.h (coop_init): Give this a real prototype.
3711 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
3712 (coop_next_runnable_thread): No need to provide prototype; it's in
3715 * scmconfig.h.in: .detarenegeR
3717 * iselect.c, threads.c: Doc fixes.
3719 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3721 * Makefile.in: Regenerated with a patched automake, to get
3722 dependency generation right when using EGCS.
3724 * inet_aton.c (inet_aton): Add prototype, to remove compiler
3725 warning. (Thanks to Robert Pluim.)
3727 * inet_aton.c (inet_aton): Reassure the compiler that the
3728 arguments to the <ctype.h> macros are all unsigned characters, not
3731 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3733 Getting rid of more warnings...
3734 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
3735 today's change to ../configure.in.
3736 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
3737 * scmconfig.h.in: Regenertaded.de.,.__
3738 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
3739 (scm_localtime, scm_mktime): Use a const char * to manipulate the
3742 * readline.c: Doc fix.
3743 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
3744 * readline.h (scm_filename_completion_function): Add prototype.
3745 (scm_init_readline): Make this into a prototype.
3747 * readline.c (scm_filename_completion_function): Use SCM_PROC to
3748 declare this, instead of calling scm_make_subr manually.
3750 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
3752 * readline.h (scm_init_readline): Add prototype for this.
3753 (scm_init_readline): Make this a real prototype.
3755 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
3757 Warning fixes from Maciej Stachowiak:
3758 * backtrace.h (scm_display_application, scm_backtrace): Add
3760 * debug.c (scm_m_start_stack): Make this function static.
3761 * fluids.h (scm_fluid_p): Add prototype.
3762 * procprop.c (scm_i_procedure_arity): Make this function static.
3763 * regex-posix.c (scm_regexp_error_msg): Make this function static.
3764 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
3765 * root.h (scm_dynamic_root): Add external prototype.
3766 * scmsigs.h (scm_usleep): Add external prototype.
3767 * script.h (scm_init_script): Use prototype, not K&R decl.
3768 * stacks.h (scm_stack_id): Add external prototype.
3769 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
3771 1998-09-30 Mark Galassi <rosalia@cygnus.com>
3773 * gh.h: took out the definitions of vset and vref, since they are
3774 replaced by the proper vector routines that correspond to the R4RS
3777 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
3779 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
3780 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
3781 third argument, a C expression that should result in a SCM value,
3782 which is used to initialize the variable. Reimplemented
3783 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
3786 * version.h (scm_libguile_config_stamp): Add prototype.
3787 (From Maciej Stachowiak.)
3789 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
3791 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
3792 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
3794 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
3796 * print.c (scm_iprin1): Rather than having one i, and using it in
3797 several places, declare a fresh i local to each block where it is
3798 used, and give it a signedness appropriate to its use in each case.
3799 (scm_iprlist): Same.
3801 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
3802 comparison warnings.
3804 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
3805 signed/unsigned clashes.
3807 * posix.h (scm_tmpnam): Added prototype.
3809 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
3810 scm_make_subclass_object): Add external prototypes.
3812 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
3813 comparison is okay here.
3815 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
3817 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
3818 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
3820 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
3823 * load.c (swap_port): Make this function static.
3825 * load.c (scm_search_path): Make max_path_len and max_ext_len
3826 unsigned, since they're compared against string sizes.
3828 * load.c (init_build_info): Make i unsigned.
3830 * ioext.h (scm_read_line): Add prototype.
3832 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
3833 scm_hash_fn_remove_x): Make hash bucket index local variable k
3834 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
3835 accurately as possible.
3837 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
3838 comparisons, and range checking to make sure those casts are
3841 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
3842 signed/unsigned comparisons.
3844 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
3845 avoid signed/unsigned comparisons.
3846 * smob.h (scm_numsmob): Change extern declaration to match.
3848 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
3849 avoid signed/unsigned comparisons.
3850 * ports.h (scm_numptob): Change extern declaration to match.
3851 (scm_current_load_port, scm_set_port_line_x,
3852 scm_set_port_column_x): New prototypes.
3854 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
3855 test code, and it causes warnings.
3857 * gh.h (gh_int2scmb, gh_uniform_vector_length,
3858 gh_uniform_vector_ref): Added prototypes.
3860 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
3861 debugging support unconditionally. That's backtrace.c, stack.c,
3862 debug.c, and srcprop.c.
3863 (EXTRA_libguile_la_SOURCES): Omit those from here.
3864 * Makefile.in: Regenerated.
3866 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3868 * options.c (scm_options): Bugfix: Allow empty list of options!
3870 * debug.c, debug.h (scm_single_step): Removed.
3871 (scm_with_traps): New procedure. This procedure could easily be
3872 written in Scheme but needs to be highly optimized.
3874 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
3876 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
3877 Check SCM_TRAPS_P before trapping.
3879 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
3881 Changes to avoid signed/unsigned comparison warnings.
3882 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
3883 (scm_gc_sweep): Make n and j local to the blocks they're used in,
3884 so they can have appropriate types for each application. Make i
3885 signed. Use initializers in some spots. I'll probably pay for
3887 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
3888 (scm_must_realloc): Make nm unsigned.
3889 (init_heap_seg): Make new_seg_index and n_new_objects signed.
3890 (scm_init_storage): Use prototype-style definition, and make the
3892 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
3893 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
3895 * filesys.c (scm_readlink): Make local vars rv and size ints, to
3896 avoid signed/unsigned comparison warnings, and because the return
3897 value of readlink may be -1. Don't bother casting the third
3898 argument to readlink.
3900 * filesys.c (scm_dirname, scm_basename): Move these to their own
3901 page, at the end of the file.
3902 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
3904 * eval.h (scm_eval_options_interface): Add external prototype for this.
3905 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
3907 * eval.c (scm_lookupcar1): Make this static.
3909 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
3910 Make these prototype declarations, not K&R-style.
3912 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
3913 unsigned comparison warning.
3915 * appinit.c: File removed. It had a single function in it, empty,
3916 whose reason for existence is explained in no documentation or
3917 comment. I think it's there as a default for some Tcl-style
3918 initialization, but Tcl abandoned that approach a while ago.
3919 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
3920 (BUILT_SOURCES): Remove appinit.x.
3921 * Makefile.in: Regenerated.
3923 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3925 * Makefile.in: Regenerated using the last public version of
3926 automake, not the hacked Cygnus version.
3928 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
3930 Remove Totoro kludge.
3931 * Makefile.in, scmconfig.h.in: Regenerated.
3932 * init.c, readline.c: Don't check if TOTORO is #defined.
3934 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
3936 * Makefile.am: Adjust for new thread configuration system.
3937 (INCLUDES): Include the value of THREAD_CPPFLAGS.
3938 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3940 (THREAD_LIBS): Definition deleted; automake will generate such
3941 things automatically.
3942 * Makefile.in: Regenerated.
3944 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3946 Simplify smob and port marking; set the mark bit in the generic
3947 marking code, and make marker routines only responsible for
3948 turning up outgoing pointers.
3949 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3950 before calling the marking function. Don't call the marking
3951 function if it's zero.
3952 * markers.c (scm_mark0): Just return #f. This function isn't
3953 necessary at all now, but it's harmless to call it. We'll leave
3954 it in so other folks' code doesn't croak at link time.
3955 (scm_markcdr): Don't call SCM_SETGC8MARK.
3956 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3957 * dynl.c (mark_dynl_obj): Same.
3958 * root.c (mark_root): Same.
3959 * srcprop.c (marksrcprops): Same.
3960 * unif.c (markra): Same.
3961 * variable.c (scm_markvar): Same.
3962 * ports.c (scm_markstream): Same.
3963 (void_port_ptob): Specify zero for our marking function.
3964 * debug.c (debugobjsmob): Same.
3965 * dynwind.c (guardsmob): Same.
3966 * filesys.c (dir_smob): Same.
3967 * fluids.c (fluid_smob): Same.
3968 * fports.c (scm_fptob, scm_pipob): Same.
3969 * mallocs.c (mallocsmob): Same.
3970 * regex-posix.c (regex_t_smob): Same.
3971 * smob.c (freecell, flob, bigob): Same.
3972 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
3973 * throw.c (jbsmob, lazy_catch_funs): Same.
3975 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3977 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
3978 scm_copy_tree on code in order not to let memoized code to leak
3979 out. Thus, scm_copy_tree needs to copy vectors as well since
3980 quasiquote can introduce evaluated code also inside vector
3983 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3985 * eval.c (scm_copy_tree): Removed ability to copy vectors.
3987 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
3988 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
3991 * unif.c: Say that ivect and uvect are of type signed and unsigned
3992 long instead of int in commentary so that it correctly describes
3995 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3997 * stime.c: Removed declaration of strptime. (It should be
3998 declared by the system headers. If it turns out that some systems
3999 don't, we'll handle that then.) (Thanks to Greg Troxel.)
4001 * stime.h: Renamed TIMEH --> STIMEH
4003 * backtrace.c (scm_display_error, scm_display_backtrace): In order
4004 to increase portability, don't use structure assignment.
4005 (Thanks to Nicolas Neuss.)
4007 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
4009 (finalize_fd_sets): Added empty statement after last case label.
4010 (Thanks to Nicolas Neuss.)
4012 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
4015 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
4017 * init.c, readline.c: OK, I won't have these readline.x bug
4018 reports anymore. We've had them since April. The current reason
4019 is a completely unintelligible failure of totoro.red-bean.com to
4020 do the test for rl_getc_function in libreadline correctly. This
4021 kludge overrides the test if we're on totoro so that the snapshot
4022 generation process can work.
4024 * readline.c: Define a strdup replacement if not existent on system.
4026 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
4028 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
4029 This change makes scm_make_vector R5RS compatible. We cannot keep
4030 the third argument since people want to be able to deduce the form
4031 of the C function call only by looking at R5RS. (At the same time
4032 we have removed some unnecessary complexity!)
4034 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
4035 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
4036 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
4037 argument in call to scm_make_vector.
4039 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4041 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
4042 This macro is useful in applications.
4044 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
4046 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
4047 (scm_parse_path, scm_search_path): New Scheme level procedures.
4049 * load.h (scm_internal_parse_path, scm_parse_path,
4050 scm_search_path): Declared.
4052 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4054 * filesys.c (dirname, basename): New procedures.
4056 * init.c (scm_boot_guile_1): Removed condition around
4059 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
4060 new data type (guards) for representation of C level guards and
4061 data on the wind chain.
4062 (scm_internal_dynamic_wind): New function.
4064 * dynwind.h: Declare scm_internal_dynamic_wind.
4066 * root.h (scm_root_state): Added scm_cur_loadp.
4068 * root.c (mark_root): Added comment about cur_loadp.
4070 * load.c: #include "dynwind.h";
4071 (scm_primitive_load): Use scm_inner_dynamic_wind to update
4074 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
4076 * ports.c (current-load-port): New procedure.
4078 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4080 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
4081 not a tty, return #f.
4083 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
4084 to Julian Satchell and Roland Kaufmann.)
4086 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
4087 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
4089 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
4091 * debug.h, debug.c (scm_start_stack): New function. Implements
4092 the guts of old scm_m_start_stack.
4094 * debug.c (scm_m_start_stack): Use scm_start_stack.
4096 * init.c (scm_start_stack, scm_restart_stack): Renamed to
4097 start_stack and restart_stack. (These have static scope.)
4099 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4101 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
4102 readline functions to come in release 2.3. (Thanks to Chet
4104 (handle_errors): Use the above functions.
4106 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4108 * readline.c: Improvements for readline support: Handle errors
4109 better; Implement before-read-hook.
4111 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4113 * init.c (scm_boot_guile_1), readline.c: Test for
4114 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
4115 assure that we have version >= 2.1.)
4117 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
4119 * readline.c (scm_readline): Defer interrupts while we're calling
4122 * readline.c (scm_add_history): Bugfix: Do strdup before giving
4123 away the string to add_history.
4124 (completion_function): Do completion for readline. (Thanks to
4126 (scm_filename_completion_function): New procedure: Filename
4128 (current_input_getc): New function. Use this one instead of
4129 standard getc from readline.
4131 * throw.c, throw.h (scm_handle_by_throw): New function: This
4132 handler throws errors to next handler on the dynwind chain.
4134 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
4136 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
4139 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4141 * procprop.c (scm_i_procedure_arity): New function. Returns arity
4143 (scm_procedure_properties): Modified to return arity together with
4145 (scm_procedure_property): Added the read-only property `arity'.
4146 (scm_set_procedure_property_x): It is an error to set the `arity'
4149 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
4150 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
4152 * procprop.h (scm_sym_arity): New symbol.
4154 * objects.c (scm_set_object_procedure_x): New procedure: Use this
4155 to set the dispatch procedure of an operator or entity object.
4157 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
4158 Made procedure slots read-only.
4160 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
4161 scm_tcs_cons_gloc case in zero args switch; Fixed args
4162 construction for operators in scm_tcs_cons_gloc case in two args
4165 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4167 * fluids.c: Removed use of assert.h (in order to avoid
4170 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
4172 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
4174 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
4175 change makes the evaluator safer at the cost of evaluation speed.
4176 It handles the case when the user has added a non-immediate
4177 improper end of the application form, e.g., `(+ 0 . x)'.
4178 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
4179 minimize the extra cost as much as possible. The new code is
4180 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
4181 problem with structs planted directly in the code (e.g. by a
4182 macro). This no longer causes segmentation fault. (Thanks to
4185 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
4186 arg `proc' in order to be able to throw errors; New argument
4189 * Removed extra #include "debug.h"
4191 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
4193 * scmsigs.c: Declare usleep as returning void on some systems.
4194 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
4197 * coop.c (usleep): Return void on some systems.
4199 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4201 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
4203 * coop.c: Changed return type of usleep to int.
4205 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
4206 isn't found in the OS.
4208 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
4209 isn't enabled. (Thought that I had made this change ages ago...)
4211 * iselect.c: Declare bzero if not defined by OS.
4213 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4215 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
4216 condition. (Thanks to John Tobey.)
4218 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
4219 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
4222 * __scm.h: Start the long-term project of moving to POSIX threads.
4223 Phase 1: Classification of all critical sections.
4224 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
4225 for A sections. (See comments in __scm.h for details.)
4227 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
4228 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
4230 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4232 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
4233 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
4234 (libpath.h, versiondat.h): Replaced dependency on Makefile with
4235 dependencies on $(srcdir)/Makefile.in
4236 $(top_builddir)/config.status in order to avoid circularity.
4238 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
4239 from argc if argc was 0 initially.
4241 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
4242 in generation of libpath.h.
4244 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
4246 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
4247 libguile from 2 to 3.
4249 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
4251 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
4253 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
4255 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
4256 scm_set_port_column_x, scm_port_filename,
4257 scm_set_port_filename_x): Removed optional arguments. Added
4258 proper argument checking.
4260 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
4261 stack size in machine words.
4263 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
4264 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
4265 to Ole Myren Röhne.)
4267 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
4269 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
4270 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
4272 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
4275 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
4276 procedure apply: Copy argument lists before pushing them unto the
4277 environment so that the environment won't get mutated due to
4278 manipulation of procedure arguments. This should perhaps be
4279 regarded as a temporary solution until someone finds a more
4280 efficient one. (Thanks to Maciej Stachowiak.)
4282 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
4284 * script.c (scm_compile_shell_switches): Use "guile" as default
4285 zero arg if argc is NULL.
4287 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
4289 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
4290 is zero. (Thanks to Dirk Herrmann.)
4292 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
4294 * ports.c (scm_add_to_port_table): First line is now line 0
4295 (was 1). (Interface changed according to suggestion by Per
4298 * backtrace.c (display_header): Add 1 to line and column numbers
4299 when presenting them to the user.
4301 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
4302 from debug.c --> eval.c
4304 * eval.h, eval.c (scm_eval_options_interface): New options
4306 (SCM_EVAL_STACK): New option: Size of newly created stacks,
4307 i.e. stacks for new threads.
4309 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
4311 * eval.c (unsafe_setjmp): Removed with #if 0.
4313 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
4316 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
4317 to avoid compiler warnings.
4319 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
4321 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
4323 * throw.c (handler_message): Print message on current error port
4324 instead of default error port. (Thanks to Maciej Stachowiak.)
4326 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
4328 * ports.c (scm_add_to_port_table): allocate in units of
4329 struct scm_port_table *, not struct scm_port_table.
4330 * posix.c (scm_close_pipe): remove the port from the port table
4332 Thanks to Rob Engle for both fixes.
4334 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4336 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
4337 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
4339 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4341 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
4343 * backtrace.c (display_error_body, display_backtrace_body),
4344 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
4345 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
4346 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
4347 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
4350 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
4351 don't receive the jmpbuf arg anylonger.
4352 (scm_catch): Don't accept a #f tag.
4353 (scm_throw): Check that key is a symbol.
4354 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
4356 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
4358 * async.c (async_pending): Removed declaration.
4360 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4362 * dynwind.c (scm_wind_chain): New debug function.
4364 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
4365 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
4366 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
4367 extra layer of functions around the body and handler of a thread.
4368 This extra layer makes sure that the handler is called in the
4369 dynamic context of the surround (= empty dynwind list), but under
4370 the *dynamic root* of the body. We can not use the dynamic root
4371 of the surround since that root belongs to another thread => stack
4372 is not handled correctly. It may seem ugly to use this extra
4373 layer, but the extra cost in terms of execution time is really
4374 negligible compared to the total amount of time required to create
4375 a thread, and it would reduce maintainability to duplicate the
4376 crucial and complicated steps performed by cwdr.
4378 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
4379 (SCM_ALLOW_INTS): Added thread switching code before interrupts
4380 get re-enabled. The important effect of this is that interrupts
4381 are blocked during thread switching so that thread data structures
4382 don't risk getting messed up by an unfortunate signal.
4383 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
4384 seems to do more aggressive optimization which actually move
4385 instructions around in these macros in a fatal way. Therefore:
4386 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
4387 just superstitious...)
4388 (SCM_TICK): Maybe do a context switch and take care of asyncs.
4389 This macro should be used instead of SCM_ASYNC_TICK since the
4390 latter doesn't do context switches any more.
4392 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
4393 instead of SCM_ASYNC_TICK.
4395 * coop.c, iselect.c: Since thread switches are now performed with
4396 interrupts masked, we can't use the old mechanism of delivering
4397 signals immediately when they arrive. Signals must instead be
4398 delivered when the asyncs run *after* the end of the critical
4399 section in scm_internal_select. But this also means after context
4400 switch so that the signal will be delivered to a different thread.
4401 To avoid this, I have changed the protocol of
4402 coop_wait_for_runnable_thread and friends so that they are allowed
4403 to return the original thread. So, if a signal arrives during
4404 scm_internal_select, we won't any longer be forced do a context
4405 switch, but can remain in the same thread and deliver the signal
4408 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
4409 scm_asyncs_pending and made it global.
4411 * iselect.c: Small fixes.
4413 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
4414 coop_condition_variable_init, coop_condition_variable_wait,
4415 coop_condition_variable_signal): Changed return type from `void'
4416 to `int'. This is to adhere closer to the pthreads interface.
4417 This, in turn, is part of an attempt to provide C versions of the
4418 mutex and condition variable primitives which can be part of a
4419 frontend to COOP or pthreads.
4421 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
4422 coop_condition_variable_destroy): New functions.
4424 * coop-threads.c (scm_wait_condition_variable): Use
4425 coop_condition_variable_wait_mutex.
4427 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
4428 Definitions moved to coop-defs.h.
4430 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
4431 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
4432 scm_cond_destroy): New C interface to mutecis and cond vars.
4434 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4436 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
4438 * iselect.c: Now several threads can wait on the same file
4439 descriptor. The behaviour is compatible with OS select: All
4440 threads waiting for the fd return with the same status.
4442 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4444 * coop-threads.c, threads.h (scm_spawn_thread): New function.
4445 Can spawn a thread from application C code.
4447 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4449 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
4450 gh_doubles2scm): New functions.
4452 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
4454 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
4455 commented-out version of gh_eval_str()
4457 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
4459 * socket.c (scm_bind): free soka after use.
4461 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
4463 * stime.c (tzvar): new variable.
4464 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
4465 avoid memory leaks when allocating.
4467 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
4469 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
4472 * gc.c, tags.h: Doc fixes.
4474 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4476 * eval.c (macro-eval!): Removed. This function was a design bug.
4477 It allowed memoized code to leak out to the scheme level. Most
4478 things that you could do with `macro-eval!' can be done with
4481 1997-12-20 Tim Pierce <twp@skepsis.com>
4483 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
4484 scm_fgets now depends on ftell(3) to know how many bytes were
4487 1997-12-15 Tim Pierce <twp@skepsis.com>
4489 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
4490 dealing with strings.
4492 1997-12-13 Tim Pierce <twp@skepsis.com>
4494 Make %read-line more suitable for implementing read-line efficiently.
4495 * ioext.c (scm_read_line): Strip the terminating newline from a
4496 string, and return a cons of the string and its terminator.
4498 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
4499 of the string that is read is stored in this memory location.
4500 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
4501 * genio.c, genio.h (scm_do_read_line): Update caller.
4502 * ports.h (scm_ptobfuns): Update typedef.
4503 * fports.c (scm_fptob, scm_pipob): Update struct.
4505 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4507 * filesys.c (set_element): Return file descriptor.
4508 (fill_select_type): Return the highest file descriptor.
4509 (scm_select): Tell select about the highest file descriptor. On
4510 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
4511 Therefore the extra overhead for calculating the maximum fd seems
4512 to be more than compensated. Is this correct? In any case,
4513 scm_internal_select will be much faster with this info.
4514 (scm_select, fill_select_type, set_element): Don't accept any kind
4515 of object in the file descriptor list or vector.
4517 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4519 * iselect.c (finalize_fd_sets): Bugfix.
4521 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4523 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
4524 when using scm_internal_select (since we might switch to another
4527 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
4529 * simpos.c (scm_system): always define: use sysmissing if not
4530 available. Check for HAVE_SYSTEM instead of _Windows (does
4531 Windows lack system or does it have an unusable one?).
4532 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
4533 Let the argument be optional: if not supplied, call system(NULL).
4535 * ports.c (scm_close_port): relax the type check from OPPORTP to
4536 PORTP; closing a closed port is allowed.
4538 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
4540 * fports.c (scm_fgets): Return if the last char in a chunk is
4541 newline. When fgets returns a string whose length is `size-1', it
4542 is ambiguous whether a whole line was retrieved, so we must check
4543 explicitly whether a line terminator is present.
4545 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4547 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
4548 before taking the CDR. (Thanks to Harald Meland.)
4550 * filesys.c (scm_stat): Slightly optimized.
4552 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
4554 * ports.c (scm_close_port): Make sure the port is open before
4557 * guile-snarf.in: Pass args through to gcc in a way that preserves
4558 whitespace boundaries. (Thanks to Greg Badros.)
4560 1997-12-02 Tim Pierce <twp@skepsis.com>
4562 * stacks.c (scm_frame_procedure): Reverse the logic in the return
4563 statement. (Thanks to Doug Evans for pointing this out.)
4565 1997-12-01 Tim Pierce <twp@skepsis.com>

4596 --> the_last_stack_fluid.
4598 * backtrace.c: Added #include "fluids.h"

4625 scm_internal_select.
4626 (coop_qget, coop_qget, coop_tmp_queue): Made global.
4627 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
4628 replacement in iselect.c.
4629 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
4630 coop_join): If GUILE_ISELECT enabled, use
4631 coop_wait_for_runnable_thread instead of
4632 coop_next_runnable_thread.
4633 (usleep, sleep): New replacements for system functions if
4634 GUILE_ISELECT is enabled.
4636 * coop-threads.h: Declare coop_wait_for_runnable_thread.
4638 * coop-defs.h (coop_t): Added fields used by scm_internal_select.

4651 1997-11-27 Tim Pierce <twp@skepsis.com>
4653 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
4654 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
4655 and scm_must_free, since ultimately the string returned will be copied
4656 by scm_makfrom0str anyway. Also, read any characters that may have
4657 been pushed onto the port with scm_ungetc.
4658 * ports.c (scm_generic_fgets): Same as for scm_fgets.
4659 * ioext.c (scm_read_line): Free string after Guilifying it.

4673 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
4675 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
4676 and to invoke scm_shell().
4677 (gh_launch_pad): took out the loading of boot-9.scm from here,
4678 since it is probably best to let the user control that. In fact,
4679 gh_repl() now invokes scm_shell() which does that.
4681 1997-11-23 Mark Galassi <rosalia@cygnus.com>
4683 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

4706 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
4708 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
4710 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
4711 configure.in was changed).

4718 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
4720 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
4721 OPORT is an `open' port, not an output port.

4730 scm_close_all_ports_except, scm_set_current_output_port,
4731 scm_set_current_error_port): Likewise
4732 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
4733 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):

4746 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
4747 exactly what we want to leave in to detect substrings.
4748 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
4749 * tags.h: Fix diagrams and comments describing the S tag bit;
4750 remove vestigial remarks about the D tag bit.

4752 * strings.c: Formatting tweaks.
4754 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
4755 variable first; then SCHEME_LOAD_PATH, with a warning message.
4756 (scm_parse_path): New function.
4757 * script.c: Doc fixes.

4769 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4771 * gh.h: gh_vector_set -> gh_vector_set_x
4773 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4775 * gh_data.c (gh_vector_set_x): changed name to make it consistent
4776 with the ! -> _x mapping when going from Scheme to C.
4778 1997-10-19 Mark Galassi <rosalia@cygnus.com>
4780 * gh.h (gh_reverse):

4799 complete the picture R4RS functions that should be mirrored in the
4802 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4804 * tags.h (scm_tc7_substring): Changed the comment and code to
4805 conform with the changes below. Folks! We have suddenly two new
4806 free tc7 codes!!! Jummy, jummy!

4870 * gh_test_c.c (c_vector_test): some improvements on the vector
4873 * gh.h (gh_vector): this used to exist but do the wrong thing.
4874 Now it (almost) does the right thing, though it takes a list
4875 instead of the individual arguments. I need to see how it could
4877 (gh_list_to_vector): added this function as a macro. Corresponds
4878 to Scheme's (list->vector ...).

4886 (gh_make_vector): this used to be (stupidly) called gh_vector().
4887 This is the right name, since it does the same thing as the Scheme

4937 transformers. (They are always: exp env.); Bugfix: Unmemoize
4938 transformer source with correct environment.

4947 (cwdr_handler): New function.
4948 (scm_internal_cwdr): New function to perform the function of cwdr
4949 but take args that are more useful to C code. Also, the handler
4950 is now invoked *outside* of the new dynamic root, like the docs
4951 say. We no longer have to catch absolutely all errors, the caller
4952 is responsible for using a handler that does not throw, if he
4954 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4955 * root.h (scm_internal_cwdr): New prototype.
4957 Even more but risky streamlining:
4959 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4960 allocation of the jumpbuf of a root continuation. The changes
4961 below are controlled by it. They are now deactivated.
4962 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4963 the JMPBUF of the scm_rootcont to NULL before returning.
4965 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
4966 when they are non-NULL.

4987 one or when it returns #f.
4988 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
4989 Accept a port/print-state pair in addition to just a port.
4990 (scm_prin1): Don't return the print_state to the pool when it has
4992 (scm_printer_apply): Set `revealed' field of print_state to true.
4993 (scm_init_print): Set scm_print_state_vtable.
4994 (print_state_fluid, print_state_fluid_num): Removed.

5010 * strports.c (scm_eval_string): Don't close the port.
5012 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
5013 former returns a nice normal integer. (Thanks to Daniel
5016 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
5018 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
5019 makefile variable as a build parameter called LIBS. The
5020 build-guile program will use this, for the time being.
5021 * Makefile.in: Regenerated.
5023 Thanks to Shiro Kawai:
5024 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
5025 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
5028 * Makefile.in: Regenerated with automake 1.2a.
5030 * script.c (scm_compile_shell_switches): If we hit the -c or --
5031 arguments, don't set the car of (command-line) to scm_usage_name,
5032 the prettified name of the guile executable; give it the full
5033 path, the way shells usually handle $0.
5035 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5037 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
5038 Scheme-level name `array-map' and renamed `serial-array-map' to
5039 `serial-array-map!'.
5041 * backtrace.c: Introduced exception handlers which now enclose
5042 `display-error' and `display-backtrace' so that error reporting
5043 won't get into infinite loops if an error occurs during displaying
5044 of the error. This can very easily happen with user supplied
5045 print call-back routines.
5047 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5049 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
5050 the names `serial-array-map' and `array-map' should be removed.)
5052 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
5054 * init.c (scm_boot_guile_1): Added scm_init_objects ().
5055 Added #include "objects.h"
5057 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
5058 Add #include "feature.h".
5060 * Makefile.am (libguile_la_SOURCES): Added objects.c.
5061 (modinclude_HEADERS): Added objects.h.
5063 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
5064 This test is needed at many places in the code and should be
5065 abstracted. (Motivated by the need of this test in libguiletk.)
5067 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
5068 (scm_eval_string), load.c (scm_primitive_load,
5069 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
5070 Use SCM_EOF_OBJECT_P.
5072 * eval.c (scm_init_eval): Add feature `delay'.
5074 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5076 * scmhob.h: Removed.
5078 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5080 * list.h (SCM_LISTn): New macros. Make list creation in C code
5081 prettier. The idea comes from STk.
5083 * sequences.h, sequences.c, append.h, append.c: Removed. These
5084 files implemented non-R4RS operations which would encourage
5085 non-portable programming style and less easy-to-read code.
5087 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
5090 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
5091 sequences.h, #include append.h.
5093 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
5096 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
5098 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
5100 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
5102 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5104 * eval.c: Added #include "objects.h"
5106 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
5109 * smob.c (scm_smob_prehistory): Create two objectsmobs with
5110 adjacent smob numbers.
5112 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5114 * procprop.h: Added declaration of scm_i_inner_name.
5116 * gsubr.c: New global symbol scm_i_inner_name.
5118 * debug.c (scm_procedure_name): Try procedure property
5119 `inner-name' if `name' fails.
5121 * print.c (scm_iprin1): Use scm_macro_name.
5123 * eval.c (scm_m_define): Give names to macros as well; Only the
5124 first top-level definition gives a procedure/macro a name.
5125 Otherwise confusing names can turn up in backtraces.
5126 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
5127 `name'; Give names to macros as well.
5129 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
5130 (scm_macro_transformer): Use SCM_CLOSUREP instead of
5133 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5135 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
5137 (prinmacro): Removed. The code has been moved/merged into print.c
5138 in order to decrease code redundancy. We want macros to print in
5139 a way equivalent to procedures, and it would be silly to duplicate
5140 the required code. (We don't want to maintain two places.)
5141 (macrosmob): Print field is now a NULL pointer.
5143 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
5144 scm_macro_transformer): New prototypes.
5145 (scm_tc16_macro): Declared.
5147 * print.c (scm_iprin1): Added code for printing of macros. Macros
5148 are now printed in a way equivalent to procedures.
5150 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
5152 * procs.h (scm_closure_p): Added declaration.
5154 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5156 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
5157 Shouldn't pass "heap" as the subr name.
5159 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
5161 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
5162 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
5163 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
5164 gh_equal_p): Use SCM_NFALSEP, instead of testing against
5165 SCM_BOOL_T. Any non-false value is true.
5167 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5169 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
5170 scm_gensym): Added prototypes.
5172 * symbols.c (scm_gensym): New function. This will speed up
5173 certain types of applications (such as macro systems) which
5174 generate lots of symbols.
5176 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5178 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
5180 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
5182 * unif.c (scm_shap2ra): tighten the checking of the array dimension
5183 specifier, since (2) or (2 . 3) would cause SEGV.
5184 (scm_transpose_array): more argument checking fixes.
5186 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
5188 * Makefile.in: Regenerated.
5190 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
5192 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
5194 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5196 * error.c, error.h (scm_error_callback): Removed (see NEWS).
5198 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
5200 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
5201 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
5204 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
5205 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
5206 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
5207 scm_array_p, scm_array_rank, scm_array_dimensions,
5208 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
5209 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
5210 scm_array_prototype): Added case scm_tc7_wvect.
5212 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
5214 * errno.h: prototype for scm_strerror.
5215 * error.c (scm_strerror): new procedure.
5217 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5219 * list.c (scm_list_append_x): Allow non-pair as last argument.
5220 This is consistent with the R4RS append and is probably the
5221 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
5223 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
5225 * stime.h: prototype for scm_times.
5226 * stime.c (scm_times): new procedure.
5227 * ioext.c (scm_fseek): if the first argument is a file descriptor
5229 (scm_ftell): if the first argument is a file descriptor call lseek
5231 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
5232 * filesys.c (scm_chmod): if the first argument is a file descriptor,
5234 (scm_chown): if the first argument is a port or file descriptor,
5236 (scm_truncate_file): new procedure.
5237 Add DEFER/ALLOW INTS to a few other procedures.
5238 (scm_fsync): new procedure.
5239 (scm_open_fdes): new procedure.
5240 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
5242 (scm_fcntl): the first argument can now be a file descriptor. The
5243 third argument is now optional.
5245 * posix.c (scm_execl, scm_execlp): make the filename argument
5246 compulsory, since omitting it causes SEGV.
5247 (scm_sync): return unspecified instead of #f.
5248 (scm_execle): new procedure.
5249 (environ_list_to_c): new procedure.
5250 (scm_environ): use environ_list_to_c. disable interrupts.
5251 (scm_convert_exec_args): take pos and subr arguments and
5252 improve error checking.
5254 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5256 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
5257 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
5258 argument to SCM_ASSERT. Furthermore, the name of the function
5259 should be passed as first argument when signalling
5260 SCM_WNA. (Thanks to Thomas Morgan)
5262 * gsubr.c (scm_gsubr_apply): From Radey Shouman
5263 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
5264 dispatches on the number of actual args has a default case
5265 reporting an internal error. This is a vestige from a version
5266 that mallocated a SCM vector to hold the arguments. In the
5267 current version this check is too late: if it ever happens we will
5268 have already overstepped the bounds of the array.
5270 Also, the patch [...] adds a check for too many actual arguments."
5272 mdj: Removed check for "internal programming error".
5274 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5276 * gh_io.c (gh_write): New function.
5278 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
5279 throw.c (scm_internal_stack_catch): New sibling to the other catch
5280 functions. Code moved from gh_eval.c.
5281 throw.h: Added header.
5282 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
5283 scm_internal_stack_catch.
5285 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5287 * ioext.h: fix up prototypes.
5288 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
5289 Scheme name is now dup->fdes.
5290 (scm_dup_to_fdes): make the second argument optional and
5291 fold in the functionality of scm_primitive_dup.
5292 (scm_primitive_dup): deleted.
5294 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
5296 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
5297 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
5298 ultrix are defined. Use setvbuf instead of setbuf.
5299 (scm_setvbuf): new procedure.
5300 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
5301 (scm_setfileno): moved from ioext.c.
5302 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
5303 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
5305 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5307 * fluids.c (scm_fluid_p): New function.
5308 * fluids.h (scm_fluid_p): New prototype.

5312 * print.c (scm_iprin1): Enter printed structures into the print
5313 state as nested data while they are printed.
5314 (print_state_fluid, print_state_fluid_num): New variables.
5315 (scm_init_print): Initialize them.
5316 (scm_iprin): If print_state_fluid carries a print_state, use that
5317 instead of creating a new one.
5318 (scm_printer_apply, apply_stub, struct apply_data): New
5319 definitions to help with calling printer functions written in
5321 * print.h (scm_printer_apply): New prototype.
5323 * struct.c (scm_print_struct): Use scm_printer_apply to call the
5324 user defined struct printer.
5326 * dynwind.c (scm_dowinds): Handle fluids on the wind list.
5327 * fluids.h (scm_internal_with_fluids, scm_with_fluids,

5334 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
5335 SCM_ASSERT: arg comes before pos.
5337 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5339 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
5340 to a list of length zero correctly.
5342 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5344 Supply an `fgets' method for port objects to do fast line i/o.
5345 * ioext.c (scm_read_line): New function.
5346 * genio.c (scm_gen_read_line): New function.
5347 * fports.c (scm_fgets): New function.
5348 (scm_fptob, scm_pipob): Add scm_fgets method.

5358 * ioext.h: removed scm_duplicate_port prototype.
5360 * ioext.c (scm_primitive_dup2): return the new file descriptor
5361 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
5363 (scm_fdopen): bug fix: don't try to make port unbuffered until its
5364 stream has been set.
5365 (scm_duplicate_port): deleted, there's now an implementation in
5367 (scm_primitive_dup2): do nothing if newfd == oldfd.
5369 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
5371 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
5374 * ioext.h: new prototypes.
5375 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
5377 * fluids.c (next_fluid_num): don't do
5378 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
5380 * ports.h: prototypes too.
5381 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
5383 * fports.h: prototype too.
5384 * fports.c (scm_evict_ports): moved from ioext.c.
5386 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5388 * ports.c (scm_close_port): return a boolean instead of unspecified.

5393 and ports (scsh compatible).
5395 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
5398 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
5400 * fluids.c, fluid.h: New files.
5401 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
5402 (modinclude_HEADERS): Added "fluids.h"

5410 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
5411 (scm_make_root): Call scm_copy_fluids to make fluid bindings
5412 unique for the new root when it has a parent.
5414 * smob.h: Include "libguile/print.h" to make scm_print_state
5417 * dynl.c (free_dynl_obj): New function to free the dynamic object
5418 data. (dynl_smob): Use it.
5419 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
5420 the dynamic object data below the linking of the object to avoid
5421 memory leak when the linking code throws an error. Now the code
5422 leaks a whole dynamically linked library when must_malloc throws,
5423 but that should be much less likely.
5425 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
5427 Changes to compile under gnu-win32, from Marcus Daniels:
5428 * stime.c (tzset): If tzset isn't provided, make it a NOP.
5429 (scm_localtime): Change SCM_EOF to SCM_EOL.
5430 (scm_mktime): Likewise.
5431 * socket.c: Don't include sys/un.h unless autoconf tells
5432 us Unix domain sockets are available.
5433 (scm_fill_sockaddr): Ignore Unix domain code.
5434 (scm_addr_vector): Likewise.
5435 (scm_init_addr_buffer): Likewise.
5436 (scm_socketpair): Don't include unless socketpair was

5439 * scmsigs.c (scm_pause): Don't include unless pause was found
5441 * posix.c (scm_getgroups): Don't include unless support function
5442 was found during autoconf (in this case, getgroups).
5443 (scm_setpwent): For setpwent.
5444 (scm_setegid): For setegid.
5445 * net_db.c (scm_inet_netof): Don't include unless support
5446 function was found during autoconf (in this case, inet_netof).
5447 (scm_lnaof): For inet_lnaof.
5448 (scm_inet_makeaddr): For inet_makeaddr.

5460 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
5461 scm_misc_error, not SCM_EOF.
5463 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
5464 arguments for formatting the error message, not SCM_BOOL_F. I
5465 think this is left over from the (eq? '() #f) days.
5467 * read.c (recsexpr): Give this a dummy definition if
5468 DEBUG_EXTENSIONS isn't #defined.
5470 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
5472 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
5475 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>

5480 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
5482 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
5483 alloca.lo will be included in @LIBLOBJS@. Something better than
5484 this should be possible.
5485 * Makefile.in: Regenerated.
5487 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
5489 * simpos.h: prototype for scm_primitive_exit.
5490 * simpos.c (scm_primitive_exit): new procedure, terminates the
5491 process without unwinding the stack.
5493 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
5495 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
5496 argument and logior its components together, so the user doesn't
5497 have to do this explicitly. Also, if regexp/basic is supplied, then
5498 turn off REG_EXTENDED.
5499 (scm_init_regex_posix): New regexp/basic symbol.
5500 (REG_BASIC): #define this if it is not already present.
5502 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5504 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
5505 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
5506 (CLEANFILES): New target, clean versiondat.h, libpath.h.
5507 (DISTCLEANFILES): New target, clean *.x.
5508 * Makefile.in: Regenerated.

5513 years in usage message.
5515 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
5516 * Makefile.in: Regenerated.
5518 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
5519 flag; I don't think we support it.
5520 (scm_make_regexp): Make sure the user doesn't pass the
5523 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
5525 (scm_init_regex_posix): Define constants for the REG_mumble flags;
5526 name them according to the SCSH convention: regexp/mumble.
5528 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
5530 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
5532 * Makefile.am (libpath.h): Include the values of all the standard
5533 Makefile directory variables. Print a message, but don't print
5535 (versiondat.h): Print a message, but don't print all the commands.
5536 * load.c: #include "alist.h".
5537 (init_build_info): New function.
5538 (scm_init_load): Call it.
5539 * Makefile.in: Regenerated.
5541 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
5543 * root.c: Establish a reliable catch-all handler for the new root.
5544 After all the Scheme handler function might signal an error too,
5545 and we don't want to lose that.
5546 (cwdr_inner_body): Renamed from cwdr_body.
5547 (cwdr_outer_body): New function, to establish the user's handler,
5548 and pass control to cwdr_inner_body.
5549 (cwdr): Establish the reliable catch-all handler here, and pass
5550 control to cwdr_outer_body.
5551 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
5552 the user's handler through to cwdr_outer_body.
5553 * throw.c (scm_handle_by_message): Move guts into....
5554 (handler_message): New static function.
5555 (scm_handle_by_message_noexit): New function.
5556 * throw.h (scm_handle_by_message_noexit): New prototype.
5558 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
5559 across this. Only works on GCC. Otherwise, we hope for the best.
5560 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
5561 the feeling that real thread systems will not need this...
5563 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
5565 Try to detect when people are using one version of libguile and a
5566 different version of ice-9. People have been skewing things and
5567 sending in bug reports.
5568 * Makefile.am (versiondat.h): New file to generate.
5569 * version.c: #include "versiondat.h", to get version info.
5570 (scm_libguile_config_stamp): New function.
5571 * script.c: #include "version.h".
5572 (scm_compile_switches): Call scm_version to get version number.
5573 * scmconfig.h.in, Makefile.in: Regenerated.
5574 * Makefile.in: Regenerated.
5576 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
5577 primitive definitions under their Scheme names.
5579 * Makefile.am (libguile_la_LDFLAGS): Update library version to
5580 1:2. Helps avoid confusion between installed and uninstalled libs.
5582 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
5585 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
5586 backslash from definition; this should be used like: GDB_INTERFACE;
5588 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5590 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
5591 new port unbuffered until its stream has been set.
5593 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
5595 * ports.h: new prototype.
5596 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
5598 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
5600 Make things compile neatly under Sun's C compiler.
5601 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
5602 * extchrs.c (xmbtowc): Make the second arg a normal char, not
5603 unsigned, because that's what the ANSI function takes.
5604 * extchrs.h (xmbtowc): Corresponding change to prototype.
5605 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
5607 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
5608 argument plain char *.
5609 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
5611 * tag.c (scm_tag): Remove unreachable statement.
5612 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
5613 top of the word, it should be unsigned.
5615 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
5616 is defined, to avoid warnings; it's only used in the
5617 conflict-checking code. Which might go away anyway.
5618 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
5619 conditionals; put the label definition in an #if too, to stifle
5622 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
5623 ChangeLog-threads in the distribution.
5624 * Makefile.in: Regenerated.
5626 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5628 * guile-snarf.in: Changed regexp to support CPPs that insert
5629 whitespace between lexical tokens (which munges the `%%%' snarf
5632 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5634 * load.c (scm_init_load_path): Append $(datadir)/guile to
5635 %load-path, so modules do not have to be installed in Guile's
5636 current version directory.
5638 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
5640 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
5641 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
5642 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
5643 call the sysdep functions with deferred ints.
5644 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
5645 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
5646 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
5649 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
5652 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
5654 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
5656 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
5658 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
5661 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
5663 * eval.c (scm_lookupcar1): New procedure to cope with a race
5664 condition during lookup (when using threads).
5665 (scm_lookupcar): Implement in terms of scm_lookupcar1.
5666 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
5669 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
5671 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
5672 supplied. (Change from Tim Pierce.)
5674 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
5676 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
5677 23:47:01 1997" changelog: Slots are now initialized with `#f' by
5678 default and not `()'. `#f' is the canonical non-value in Scheme,
5681 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5683 * struct.c (struct_printer): New variable that holds a handle on
5684 the Scheme variable *struct-printer*. This variable can be set by
5685 Scheme code to override the printing of structures.
5686 (scm_print_struct): If struct_printer is set, call it. If it is
5687 not set, or returns #f, print the structure in the old fashion.
5688 Include "eval.h" for scm_apply.
5690 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
5692 * struct.c (scm_struct_ref, scm_struct_set_x): Use
5693 scm_struct_i_n_words to get the number of fields, not
5694 -scm_struct_n_extra_words.
5696 On the route to fancier struct printing:
5697 * struct.c (scm_print_struct): New function to print a structure.
5698 Include "genio.h" to support it. This function doesn't do
5699 anything interesting right now, but I think it should be here
5701 * struct.h: Include "print.h" and add prototype for
5703 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
5704 print structures ourself.
5706 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5708 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
5709 before applying the handler in case it doesn't return.
5711 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
5713 * scmsigs.h, async.h: updated.
5715 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
5718 * posix.c (scm_uname): interpret only negative values as an error.
5719 Solaris normally returns a positive value.
5721 * script.c (scm_compile_shell_switches): if we are not going into
5722 an interactive repl, set scm_mask_ints to zero so that asyncs can
5725 * simpos.c (scm_system): don't ignore/unignore signals around
5728 * posix.c (scm_open_pipe): don't ignore/unignore signals around
5731 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
5732 done in boot-9.scm instead.
5734 * scmsigs.c, async.c: Major rewriting of signal handling code.
5735 (scm_sigaction): new procedure.
5736 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
5738 (scm_raise): return unspecified, throw error on failure.
5740 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5742 * regex-posix.c (scm_init_regex_posix): Register the "regex"
5743 feature, to help boot-9.scm decide whether to import the regex
5746 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5748 * eval.c: Include scmconfig.h at the beginning of the file so that
5749 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
5752 * regex-posix.c: #include "_scm.h" before conditionally #including
5753 <regex.h>; the former defines HAVE_REGCOMP.
5755 * regex-posix.c: #include <regex.h> conditionally, so the file is
5756 CPP'able (for dependency scanning) even on systems that don't have
5759 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5761 Add new R4RS-compliant syntax for keywords.
5762 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
5763 regardless of the setting of the `keywords' read option.
5764 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
5765 can be re-read no matter what the setting of the `keywords' read
5768 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
5770 Add support for POSIX regular expressions.
5772 * regex-posix.c, regex-posix.h: New files. (Some code
5773 is taken liberally from rx/rgx.c in the old Guile dist.)
5775 * init.c: Include regex-posix.h.
5776 (scm_boot_guile_1): Call scm_init_regex_posix.
5778 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
5779 Add regex-posix.[ch] sources.
5780 * Makefile.in: Regenerated.
5782 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
5783 to do this automatically? It didn't for me, bleh.)
5785 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
5787 * fports.c (print_pipe_port): New function.
5788 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
5789 latter doesn't even take the right arguments.
5791 * Makefile.am: Increment shared lib revision number. I think
5792 sometimes the uninstalled Guile finds the installed shared lib;
5793 Gord says doing this might help. As things turned out, I can't
5794 say whether it does.
5795 * Makefile.in: Regenerated.
5797 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
5798 passing it as the closure argument to scm_boot_guile. (Bill
5801 * ports.c (print_void_port, putc_void_port, puts_void_port,
5802 write_void_port, flush_void_port, getc_void_port, close_void_port,
5803 noop0): Use ANSI prototypes instead of K&R declarations, so the
5804 initialization of void_port_ptob gets aggressively type-checked.
5805 Fix arguments of print_void_port and write_void_port. (Bill

5841 * script.c (scm_find_executable): Use prototype-style definition
5842 here; apparently it's not quite right to have const in a prototype
5843 and then use a K&R declaration. I wonder if stuff like this will
5844 go away if we compile with -Wrequire-prototypes, or whatever that
5845 is... (Bernard URBAN)
5847 * scmhob.h: New text from Bernard URBAN.
5849 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5851 * script.c: Don't #define const on hpux. Configure takes care of
5852 this. (Thanks to Larry Schwimmer.)
5854 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
5855 decide whether to #include <unistd.h>, instead of listing a bunch
5856 of systems. Don't #include stdio twice. Removed dyked-out
5857 definition of scm_find_impl_file.
5859 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5861 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
5862 library version info to 1:0.
5863 * Makefile.in: Regenerated.
5865 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

5869 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
5870 throw.c: Update copyright years; these files have been worked on
5871 significantly in 1997, but only had copyright years for 1996.
5872 Also, change name of copyright holder on some from Mikael
5873 Djurfeldt to Free Software Foundation; he has signed papers
5874 assigning the changes to the FSF.
5876 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
5877 reason not to give the user the option.
5879 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5880 Return #f on end-of-file when scanning table (i.e. when called
5881 with no arguments). Try to catch errors, when we can.
5882 * posix.c (scm_getgrgid, scm_getpwuid): Same.
5884 * script.h (scm_shell_usage, scm_compile_shell_switches): New
5885 external declarations. These are useful.
5887 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
5889 * posix.c: don't include <sys/select.h> or define macros for
5890 select, since they were not used in this file.
5892 * filesys.c (scm_select): make the fifth parameter microseconds,
5893 not milliseconds. let the fourth parameter be either a real value
5894 or an integer or #f. The first, second and third arguments can
5895 now be vectors: the type of the corresponding return set will be
5897 (set_element, get_element): new static procedures.
5899 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
5901 * strports.c (scm_eval_string): New function.
5902 (scm_eval_0str): Trivially re-implemented in terms of
5904 * strports.h (scm_eval_string): New extern decl.
5906 * net_db.c (h_errno): Add extern decl for this.
5908 * fports.c (local_pclose): New function.
5909 (scm_pipob): Use it in the initializer here.
5912 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
5913 Use a meaningful error message when signalling an error. For
5914 this, scm_gethost must check h_errno rather than errno.
5916 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
5918 * Makefile.in: Regenerated, using automake-1.1p.
5920 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5922 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
5923 not SCM_UNSPECIFIED.
5925 * script.c (scm_compile_shell_switches): don't append (quit) if
5927 (scm_shell): call scm_exit_status and exit on the result of the
5930 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
5932 Ensure that shared substrings are handled properly when passed to
5933 a system call or other foreign function. Many thanks to Tim
5935 * symbols.h (SCM_COERCE_SUBSTR): new macro.
5936 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
5937 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
5938 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

5953 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5955 * error.c (scm_error): Add newline to error message.

5961 * dynl-shl.c: Completely replaced with new code from Bernard
5964 * script.c (scm_ice_9_already_loaded): New variable.
5965 (scm_compile_shell_switches): Use it.
5967 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5969 * filesys.c (scm_input_waiting_p): add missing third argument to
5972 * stime.c (scm_localtime): copy the result of localtime before
5973 calling gmtime in case they share a buffer.
5974 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
5977 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5979 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
5981 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
5983 * Makefile.am (check-local): New target, which causes 'make check'
5984 to run gh_test_c and gh_test_repl, with some trivial input.
5985 * Makefile.in: Rgnrtd.
5987 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
5989 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
5992 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
5994 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
5995 sure how this was supposed to work.
5996 (scm_async_click): don't send SCM_TICK_SIGNAL.
5997 (scm_init_async): don't initialize %tick-thunk.
5999 * the following change doesn't affect the Scheme interface:
6000 gc-thunk is called at the end of garbage collection. however it's
6001 no longer implemented by pretending it's a signal.
6003 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
6004 system async corresponding to scm_gc_thunk.
6005 * async.h: declare scm_gc_async.
6006 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
6007 gc-thunk directly, instead of going through a signal handler.
6008 (scm_gc_async): new variable, points to the GC system-async.
6009 (scm_init_async): save the GC async as scm_gc_async instead
6010 of using system_signal_asyncs.
6011 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
6013 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
6015 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
6016 Don't screw up if we're interrupted.
6017 * Makefile.in: Regeneradet.
6019 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
6021 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
6023 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
6024 we're not using AM_INIT_GUILE_MODULE any more.
6025 * Makefile.in: Reneregated.
6027 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
6029 Functions for finding variable bindings, grace à Tim Pierce.
6030 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
6031 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
6033 Get 'make dist' to work again.
6034 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
6035 * Makefile.in: Regenerated, like a surry without a fringe on top.
6037 Changes for reduced Guile distribution: one configure script,
6039 * configure.in, configure: Removed.
6040 * acconfig.h, acinclude.m4: Moved to parent directory, where the
6041 real configure script lives.
6042 * Makefile.in, scmconfig.h.in: Regenerated.
6044 * init.c: #include "script.h", to get prototype for script.c's
6047 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
6049 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
6050 scm_must_malloc, not raw malloc.
6052 * script.c (scm_compile_shell_switches): Dyke out debugging output
6055 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6057 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
6059 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
6060 system has them. Hope this is safe. Previously
6061 sys/timeb.h was included if HAVE_FTIME was defined or if
6062 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
6063 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
6065 * ioext.c (scm_setfileno): add missing third argument to
6066 scm_misc_error call.
6068 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
6070 * eq.c (scm_equal_p): Correctly compare strings of different
6071 varieties. (Thanks to Tim Pierce.)
6073 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
6075 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
6076 #! block comment must occur on a line all by itself.
6078 Move most of the guts of shell command processing into libguile,
6079 so guile.c can be very small (and eventuallly auto-generated. (I
6080 mean, generated mechanically, not self-generated. Hmm.))
6081 * guile.c, script.c, script.h: New source files.
6082 * init.c (scm_boot_guile_1): Call scm_init_script.
6083 * libguile.h: #include "script.h".
6084 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
6085 targets, for new executable.
6086 (libguile_la_SOURCES): Mention script.c.
6087 (modinclude_HEADERS): Add script.h.
6088 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
6089 not dynamic linking is enabled. This is because we're generating
6090 executables now. Move CY_AC_WITH_THREADS call after those, so the
6091 values of cy_cv_threads_libs captures the libs chosen above.
6092 * Makefile.in, configure, aclocal.m4: Regenerated.
6094 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
6095 We don't maintain this interface any more, and it just confuses
6098 * alloca.c: #include <scmconfig.h>, not <config.h>.
6099 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
6100 it'll get included in disties.
6102 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
6104 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
6105 be distributed, because they confuse people.
6106 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
6108 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
6110 * configure.in: check for presence of gethostent (not present on
6111 OpenBSD by default).
6112 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
6113 * configure, scmconfig.h.in: Regenerated.
6115 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
6117 * backtrace.c (scm_backtrace): Split message string across
6118 newlines properly. GCC is more tolerant of this than other
6121 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
6123 Merge threads directory into libguile.
6124 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
6125 threads.h: New source files.

6127 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
6129 (modinclude_HEADERS): Add threads.h, coop-defs.h.
6130 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
6131 coop-threads.c.cygnus, coop-threads.h.cygnus.
6132 * configure.in: If we're using threads, include threads.o in
6134 * _scm.h, libguile.h: threads.h lives in this directory now.
6135 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
6136 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
6137 currently used, but brought along for information's sake.
6138 * ChangeLog-threads: log from old 'threads' directory.
6139 * Makefile.in, configure: Rebuilt.
6141 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
6143 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
6146 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
6148 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
6150 Merge GH interface library into libguile.
6151 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
6152 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
6153 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
6154 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
6156 (EXTRA_libguile_la_SOURCES): ... here.
6157 (pkginclude_HEADERS): Add variable, to get gh.h installed.
6158 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
6159 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
6160 New variables, describing how to build the gh test programs.
6161 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
6162 build the test programs, and we probably should have been linking
6163 libguile.la against them all along, to support AIX shared libs.
6164 Add cflags for threads to CFLAGS; add libs for threads to new
6165 variable THREAD_LIBS, used in Makefile.am.
6166 * ChangeLog-gh: log from old `gh' subdirectory.
6167 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
6169 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
6171 * acconfig.h: Undo change of Apr 9; including the definition of
6172 PACKAGE in the guile headers conflicts with applications' own
6174 * scmconfig.h.in: Regenerated.
6176 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

6183 when PROC is receiving no arguments.
6185 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
6187 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
6188 have S_IFSOCK. This is the case under Ultrix.
6190 * posix.c (scm_status_exit_val, scm_status_exit_val,
6191 scm_status_term_sig, scm_status_stop_sig): Modified to work with
6192 Ultrix versions of WIFSTOPPED, etc., which assume that their
6193 arguments are lvalues (hmm).
6195 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
6197 * eval.c: Doc fixes.
6199 * throw.c: Doc fixes; rearranged.
6201 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
6203 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
6205 * acconfig.h: Added entry for PACKAGE.
6206 * scmconfig.h.in: Regenerated.
6208 Changes to work with automake-1.1n, which has better libtool support.
6209 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
6210 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
6212 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
6214 * Makefile.in: Rebuild.
6216 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6218 * stime.c (scm_mktime): take an optional zone argument.
6219 (scm_localtime): check putenv return value.
6220 (scm_strftime, scm_strptime): moved from posix.c. move #include
6222 stime.h, posix.h: update prototypes.
6223 (bdtime2c, setzone, restorezone): new static procedures.
6224 (scm_mktime, scm_strftime): use them.
6225 (scm_strftime): don't call mktime before strftime. Use
6226 filltime for return value.
6227 (filltime): convert NULL zname to #f.
6228 (scm_strptime): return a count of characters consumed, not
6229 the remaining string.
6231 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6233 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
6234 (scm_mktime): likewise.
6236 Uncomment localtime and mktime.
6238 * configure.in: add AC_STRUCT_TIMEZONE.
6240 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
6242 * stime.c (scm_init_stime): don't define ticks/sec.
6243 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
6244 return value problem and is still portable.)
6246 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6248 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
6249 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
6250 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
6251 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
6252 cpp_err_symbols.c): Corresponding changes.
6253 * Makefile.in: Regenerated.
6255 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6257 * posix.c (scm_putenv): don't check HAVE_PUTENV.
6258 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
6259 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
6260 * putenv.c: new file, from sh-utils 1.12.
6262 * posix.c (scm_environ): use malloc in place of scm_must_malloc
6263 since allocation isn't for Scheme objects.
6264 (scm_putenv): copy strings before placing in the environment.
6266 * stime.c (scm_current_time): throw an error if time returns -1,
6267 instead of returning #f.
6268 (scm_get_internal_real_time, scm_get_internal_real_time): use
6269 scm_long2num for return value instead of SCM_MAKINUM.
6271 * stime.h: prototypes updated.
6273 * stime.c (scm_time_in_msec): apparently unused, deleted.
6275 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
6277 * configure.in: check for gettimeofday.
6279 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
6280 which may be more usefully portable than a gettimeofday interface.
6282 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
6284 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not

6288 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6290 * stime.c (filltime): recovered static procedure.
6291 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from

6295 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
6297 * posix.c (scm_mknod): split the mode argument into type and perms
6298 arguments, like the extra fields returned by stat.
6300 * fports.c (scm_pipob): set the close, free and print procedures.
6301 (scm_close_pipe): new procedure.
6303 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
6304 define them in boot-9.scm
6306 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6308 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
6309 wan't defined. Don't include fd.h.
6311 * Previously fd.h was regenerated whenever configure was run,
6312 forcing a couple of files to be recompiled.
6314 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
6315 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
6316 Check for _fileno as well as _file.
6318 * ioext.c: don't fd.h.
6319 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
6322 * Change the stratigy for getting information about errno
6323 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
6324 generating lists of symbols during the build process, which will
6325 not always work, include comprehensive lists in the distribution.
6326 To help keep the lists up to date, the "check_signals" and
6327 "check_errnos" make targets can be used.
6329 * configure.in: don't check for a command to extract errno codes.
6330 * Makefile.am: update file lists, remove errnos.list and errnos.c
6331 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
6332 check_errnos targets.
6333 (CLEANFILES): remove errnos.c and errnos.list, add
6334 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
6335 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
6336 * errnos.default: deleted.
6337 * cpp_signal.c: new file.
6338 * cpp_errno.c: renamed from errnos_get.c.
6339 * cpp_err_symbols, cpp_sig_symbols: new files.
6340 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
6341 * error.c (scm_init_error): #include cpp_err_symbols instead of
6343 * posix.c (scm_init_posix): don't intern signal symbols. #include
6346 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
6348 * strop.c (scm_i_index): allow the lower bound to be equal to the
6349 length of the string, so a null string doesn't always give an error.
6351 * posix.h: new prototypes.
6352 * posix.c (scm_status_exit_val, scm_status_term_sig,
6353 scm_status_stop_sig): new functions, as in scsh. They break down
6354 process status values as returned by waitpid.
6356 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
6358 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
6359 configure doesn't know about it.
6361 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6363 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
6365 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
6366 which defines C variables with global linkage.
6368 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6370 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
6373 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
6375 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
6376 has time to check why this doesn't work well with continuations.
6378 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
6380 * Fix shell syntax error; some shells won't tolerate
6381 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
6383 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
6385 * posix.c (scm_uname): throw an error if uname fails instead
6388 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
6390 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
6393 * async.c (scm_ints_disabled): definition moved from error.c.
6395 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6397 * acconfig.h: Removed PACKAGE.
6399 * scmconfig.h.in: Regenerated.
6401 * snarf.h: g++ says it's non-portable not to specify the first
6402 argument in a varargs declaration. I introduced the first
6403 argument by using preprocessor conditionals.
6405 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
6407 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
6408 (scm_freopen): use RO string macros for filename and modes.
6409 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.

6412 (scm_mknod): use RO string macros for path.
6414 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
6415 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
6417 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
6418 use SCM_ROSTRINGP and SCM_ROCHARS.
6420 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6422 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
6425 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
6426 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
6427 support for byte vectors.
6429 * print.c (scm_iprin1): Limit number of vector elements printed
6430 according to pstate->length.
6432 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>

6437 * error.h: prototype for scm_error_scm.
6439 * error.c (scm_error_scm): new procedure, reimplements scm-error
6440 in C and uses scm_error.
6442 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6444 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
6445 pointer to the Scheme variable read-hash-procedures and intern it
6446 in scm_init_read. Modify scm_read_hash_extend and
6447 scm_get_hash_procedure to use the pointer.
6449 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6451 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
6452 (SCM_KEYWORD_STYLE): defined.
6454 * read.c (scm_read_opts): add a keywords option. This isn't a
6455 boolean option, in case someone wants to add support for DSSSL
6457 Setup scm_keyword_prefix symbol.
6458 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
6460 I've left keyword support disabled by default, since it doesn't
6461 seem to break the module system and it gives R4RS standard behaviour.
6462 It can be reactivated with (read-set! keywords 'prefix).
6464 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6466 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
6467 before constructing arbiter.
6469 * eval.c (scm_m_define): Bugfix: Check that the object is a
6470 closure before setting the procedure property!
6472 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
6474 * ports.c: Removed `ungetc-char-ready?'.
6476 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
6478 * read.c (scm_init_read): intitialise scm_read_hash_procedures
6479 (idea from Mikael: make it a pair so scm_permanent object only
6481 (scm_read_hash_extend): don't call scm_permanent_object.
6482 (ideas from Mikael): if chr is already in the list, replace its
6483 procedure instead of appending it again. If proc is #f, remove
6485 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
6487 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
6489 * gdbint.c (gdb_read): update scm_lreadr usage.
6491 * load.h: update prototypes.
6493 * load.c (scm_primitive_load, scm_read_and_eval_x,
6494 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
6496 * read.h: add prototype for scm_read_hash_extend. Change args for
6499 * read.c (scm_read_hash_procedures): new variable.
6500 (scm_read_hash_extend): new procedure.
6501 (scm_get_hash_procedure): new procedure.
6502 (scm_lreadr): use scm_get_hash_procedure instead of an argument
6503 for extended # processing.
6504 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
6505 scm_read_token): remove case_i, sharp arguments. Change callers.
6507 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
6509 * read.h (SCM_N_READ_OPTIONS): increase to 3.
6510 (SCM_CASE_INSENSITIVE_P): define.
6512 * read.c: add case-insensitive option to scm_read_opts.
6513 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
6514 to determine whether to convert symbol case.
6515 (default_case_i): definition removed.
6516 * read.c (scm_read_token): if case_i, downcase ic before doing
6519 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6521 * configure.in: Added configuration option `guile-debug'.
6522 Configure with --enable-guile-debug if you want a bunch of extra
6523 functions used for debugging when developing Guile.
6525 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
6527 * procs.c (make-cclo): New undocumented debugging procedure: Make
6528 compiled closure with internal procedure PROC and length LENGTH.
6529 Only compiled if GUILE_DEBUG is defined.
6531 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
6533 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
6535 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
6537 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
6538 with 3 or more args internally to the evaluator.
6540 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6542 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
6543 with 3 or more args internally to the evaluator. This is mainly
6544 because we don't want to pass entry and exit points of the
6545 debug support twice, but it also seems to increase the speed of
6546 the evaluator for such calls (e. g. (+ 1 2 3)).
6548 * backtrace.c (scm_display_application): New procedure:
6549 display-application; Set fancy printing parameters individually
6550 for different types of display (backtrace, error, application).
6551 (These should of course be customizable!)
6553 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
6554 clear the CHECK-flags.
6556 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6558 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
6560 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6562 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
6563 from pairs with a GLOC in the car.
6565 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
6566 otherwise `symbol-hash' will behave badly.
6567 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
6568 we get segmentation fault!
6570 * symbols.c: Added #include "weaks.h". New functions:
6571 `builtin-bindings' and `builtin-weak-bindings'. (These will be
6572 moved to an extraneous library when we split libguile.)
6574 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6576 * filesys.c (scm_stat): stat now takes fport arguments too as
6577 documented in the manual.
6579 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6581 * debug.c (scm_single_step): Bugfix: Call continuation with
6582 scm_call_continuation instead of throwing to it.
6584 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
6586 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
6587 argument wasn't declared to be optional.
6589 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6591 * stime.c (scm_init_stime): Add feature "current-time".
6593 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6595 * throw.h: prototype for scm_exit_status.
6596 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
6597 args to derive an exit status. Allows (quit) to work from a
6599 (scm_exit_status): new function.
6602 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6604 * eval.c (scm_deval): Removed some old code.
6605 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
6607 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
6610 * symbols.c (msymbolize): Bugfix: Must initialize property list to
6613 * procs.c: Introduce the existent C function scm_thunk_p at the
6614 Scheme level as well.
6616 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6618 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
6619 used from C to easily lookup the value of a symbol in the current
6622 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6624 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
6625 scm_init_unif in this file. This will also fix a previous problem
6628 * configure.in: Added AM_MAINTAINER_MODE
6630 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6632 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
6635 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6637 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
6638 source files that are not always included in libguile but should
6639 have their dependencies calculated by automake. This variable is
6640 recognized by automake, no further magic is needed.
6641 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
6642 to deal exclusively with *.lo files, as it seems. The *.o files
6643 are built automatically when the corresponding *.lo file gets
6646 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
6648 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
6651 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
6653 * unif.c (scm_array_set_x): minor change to argument error checking.
6655 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
6657 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
6658 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
6659 They should only be included in the library at configure.in's
6661 (libguile_la_LDADD): Include the appropriate .lo files here.
6662 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
6663 so we know when to build them (and their .lo bretheren).
6664 * configure.in (LIBLOBJS): New substituted variable. We let
6665 configure decide which .o files to include in LIBOBJS, and then
6666 put the corresponding list of .lo files in LIBLOBJS. The latter
6667 is what we pass to libtool.
6668 * Makefile.in, configure: regenerated.
6670 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
6672 * symbols.c (scm_sysintern0): New function. Contains the core of
6673 old scm_sysintern but doesn't take a second value argument.
6674 (scm_sysintern): Now uses scm_sysintern0.
6675 (scm_sysintern_no_module_lookup): Renamed to
6676 scm_sysintern0_no_module_lookup and doesn't take a second value
6677 argument any longer.
6679 * symbols.h (scm_sysintern0: Added declaration.
6681 * options.c (scm_init_opts): Use scm_sysintern0 instead of
6682 scm_sysintern when interning option keys. Otherwise we risk
6683 destroying the values of already interned variables.
6685 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
6686 scheme-level boolean (use SCM_NFALSEP).
6688 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
6690 (scm_backtrace): New function. (C version of old function from
6691 boot-9.scm) Motivation: Make it possible to display backtraces
6692 without depending on boot-9.scm. (I'm uncertain if this
6693 motivation is good enough...)
6695 * root.h (scm_root_state): Add member the_last_stack_var.
6696 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
6698 * root.c (mark_root): Mark scm_the_last_stack_var.
6700 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
6703 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
6705 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
6706 1. mark_lazy_catch didn't mark the smob.
6707 2. Both functions above have standard variants:
6708 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
6709 free_lazy_catch --> scm_free0.
6711 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
6713 * throw.c (scm_internal_lazy_catch): New function.
6714 (scm_lazy_catch): Rewritten to use it.
6715 (scm_ithrow): Handle the new lazy catch representation.
6716 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
6717 that doesn't have a jmpbuf is a lazy catch clause.
6718 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
6719 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
6720 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
6722 (scm_init_throw): Register the new lazy-catch smob type.
6723 * throw.h (scm_internal_lazy_catch): decl for new function.
6725 * throw.c (scm_internal_catch): Doc fixes.
6727 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
6728 configure.in. Including this might cause problems if applications
6729 that link against libguile include their own copies of alloca, but
6730 if they're using autoconf, they should be adding libguile to LIBS
6731 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
6732 the copy in libguile, and things will be okay. (I think.)
6734 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6736 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
6738 strop.h: move prototypes too.
6740 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6742 * posix.c (scm_init_posix): don't intern EINTR since it's now done
6745 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
6746 etc. I deleted them from filesys.c long ago, but didn't
6747 notice they were here too (although ineffective since
6748 sys/stat.h wasn't included).
6750 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
6752 * eval.c: Don't define alloca in GCC case. gcc will automatically
6753 use __builtin_alloca if appropriate.
6755 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
6757 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
6758 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
6759 that values of automatic variables are preserved. See comments
6760 for safe_setjmp for details.
6762 Change from Thomas Morgan:
6763 * variable.c: Include eq.h.
6764 (var_equal): New function.
6765 (variable_smob): Use var_equal as the discriminator for variables.
6767 * throw.c (s_throw): Remove extraneous declaration.
6769 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
6770 * eval.c: Add necessary CPP cruft to support that.
6771 * configure, Makefile.in, scmconfig.h.in: regenerated.
6773 Change from Thomas Morgan:
6774 * procprop.c (scm_procedure_properties): Convert the Scheme
6775 boolean returned by scm_procedure_p into a C boolean before using
6776 it as a condition for SCM_ASSERT.
6777 (scm_procedure_property): Likewise.
6779 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
6780 indications of Unixness.
6783 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6785 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
6787 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6789 * read.c (scm_lreadr): use scm_misc_error to improve one of the
6790 "unknown # object" error messages.
6792 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
6793 (scm_i_index) and declare it static. Add a 'direction' argument
6794 to indicate what way the search should go.
6795 (scm_i_index): throw out-of-range error instead of wrong-type-arg
6797 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
6798 strop.h: remove scm_i_index, scm_i_rindex prototypes.
6800 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6802 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
6804 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
6805 to avoid clash with various scsh forks.
6807 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
6809 The following two changes (ramap.c, throw.c) are motivated by the
6810 apparent unportability of forward declarations of static arrays of
6811 the form `static foo bar[];'.
6813 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
6814 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
6816 * throw.c (scm_throw): Moved above scm_ithrow.
6818 * options.h: Removed the extern declarations of scm_yes_sym and
6819 scm_no_sym since these are static.
6821 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6823 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
6825 * Makefile.am: remove AWK=@AWK@.
6826 Add a rule for generating errnos.list.
6827 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
6829 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
6830 don't extract errnos, just set a variable (avoids the
6831 need to recompile error.c just because configure is run.)
6833 * unif.h: update prototypes.
6834 * unif.c (scm_uniform_array_read,write): change the offset and
6835 length arguments to start and end, for consistency.
6837 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
6839 * ioext.h: update prototypes.
6840 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
6841 scm_read_line_x, it's a more general procedure using an
6842 interface from scsh. read-line and read-line! are now defined
6844 Note that the new read-line trims the terminator
6845 by default, previously it was appended to the returned string. An
6846 optional argument specifies how to process the terminator (scsh
6847 compatible). For the old behaviour: (read-line port 'concat).
6848 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
6849 returns a pair, but is converted to multiple values if the scsh
6852 socket.h: update prototypes.
6853 * socket.c (scm_recvfrom): for consistency with other procedures,
6854 take start and end as separate optional arguments.
6855 (scm_recv, scm_recvfrom): don't allow the second argument
6856 to be a size, only a buffer. Change the scheme names to
6857 recv! and recvfrom!. Don't return the buffer.
6859 * ioext.h, posix.h: move prototypes too.
6860 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
6861 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
6862 "read.h" and "unif.h".
6863 * ioext.c: include "chars.h"
6865 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
6867 * dynl.c: The dynamic linking and module registration functions
6868 are now defined even when dynamic linking is not available for the
6869 host system. Some of their functionality can be done without
6870 dynamic linking; when it's really needed, they throw errors.
6872 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
6874 * configure.in: Only define DYNAMIC_LINKING when one of the system
6875 dependent functions is detected.
6876 * dynl.c (scm_dynamic_func): New function to get the address of a
6877 function in a dynamic object.
6878 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
6879 produced by scm_dynamic_func as the thing to call.
6881 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
6883 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
6884 (scm_register_module_xxx, scm_registered_modules,
6885 scm_clear_registered_modules): New functions.
6887 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
6889 * symbols.c (scm_sysintern): Renamed to
6890 scm_sysintern_no_module_lookup.
6891 (scm_sysintern): New function to take the place of the old
6892 scm_sysintern. It uses the current toplevel lookup closure to give
6893 the symbol its value. This is a temporary hack to put packages
6894 like gtcltk into their own module.
6895 (scm_can_use_top_level_lookup_closure_var): New variable to tell
6896 us whether `scm_top_level_lookup_closure_var' has been initialized
6898 * eval.c (scm_init_eval): Set it.
6900 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6902 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
6903 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
6905 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
6907 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
6908 scm_sys_dup): deleted: FD capability will be added to other
6910 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
6911 scm_fd_free, fd_smob, scm_intern_fd.
6912 (scm_open): renamed from scm_sys_open. Return a port instead of
6913 an FD object. Make the mode argument optional.
6914 (scm_sys_create): deleted, it's just a special case of open.
6915 (scm_init_filesys): move interning of constants O_CREAT etc.,
6916 here (were previously using SCM_CONST_LONG macro).
6917 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
6919 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
6920 include "fports.h" and <stdio.h>
6921 (scm_stat, scm_select): don't support FD objects.
6923 * error.h: adjust scm_syserror_msg prototype.
6924 * error.c (scm_syserror_msg): take an extra argument for errno.
6925 Using the global value didn't always work, since it could be
6926 reset by procedure calls in the message or args arguments.
6928 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
6929 I don't understand why the check was there (and what about the
6932 * strop.c (scm_string_copy): allow shared substrings to be copied.
6934 * unif.h: corresponding change to prototypes.
6935 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
6936 recognize two new optional arguments: offset and length. Allow
6937 the port argument to be an integer (file descriptor, for scsh).
6938 Include <unistd.h> for "read" prototype.
6940 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6942 * socket.c: don't include filesys.h.
6944 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6946 * Makefile.am: add AWK=@AWK@ (?)
6948 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6950 Add a rule to generate errnos.c from errnos.
6951 * error.c (scm_init_error): include errnos.c.
6952 * errnos_cnvt.awk: new file, converts the list of errno codes to
6954 * errnos_get.c: new file.
6955 * errnos.default: new file, contains errnos to try if they can't
6956 be extracted from errno.h.
6957 * configure.in: if using GCC, try and extract errno codes from
6961 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6963 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
6964 * Makefile.am: Made libguile into a libtool library.
6965 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
6966 Set libtool_libs to indicate that libguile is a libtool library.
6967 See guile/ChangeLog for details.
6968 * .cvsignore: ignore "*.lo", the libtool library objects.
6970 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6972 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
6973 use htons in getservbyport argument.
6975 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6977 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
6978 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
6981 * objprop.c (scm_object_property): No need to take the CDR of the
6982 value returned by scm_object_properties, since Aug 20 change.
6984 * configure.in: When checking for struct linger, #include
6985 <sys/types.h> as well as <sys/socket.h>. I've never known
6986 <sys/types.h> to cause any portability problems, and Solaris's
6987 <sys/socket.h> needs it.
6988 * configure: Rebuilt.
6990 I think the Sun compiler has chosen a perverse way to interpret
6991 ANSI declarations combined with K&R definitions. We'll
6992 appease it a little bit. But when it invades France, we fight.
6993 * print.c (scm_iprlist): Change 'tlr' argument to an int.
6994 * print.h (scm_iprlist): Here too.
6995 * numbers.c (scm_divbigdig): Change definition to match
6996 declaration in numbers.h.
6997 * unif.c (scm_makflo): Change definition to match declaration in
7000 * init.c (scm_boot_guile): Don't return the value of
7001 scm_boot_guile_1. This function doesn't return a value;
7002 scm_boot_guile_1 doesn't return a value (or return at all).
7004 * eval.c (unmemocopy): Add a semicolon to appease the Sun
7007 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
7008 compile. I have a feeling this function is a bad idea anyway ---
7009 one should always test for features, not systems.
7011 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
7012 semicolons. Only pure luck kept this from being noticed earlier.
7014 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
7016 * socket.c (scm_recvfrom): Added missing semicolon.
7018 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
7020 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
7021 the buffer and start and end positions for scsh networking
7024 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
7026 * configure.in: Revert previous change to this file; the problem
7027 is due to transient automake weirdness.
7028 * configure: Rebuilt.
7030 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
7031 PLUGIN/guile.libs. configure generates the latter from the former.
7032 * Makefile.in: Rebuilt.
7034 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
7035 need this if we install scripts, like guile-snarf.
7036 * configure: Rebuilt.
7038 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
7040 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
7042 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
7044 * socket.c (scm_addr_vector): fix faulty scm_listify.
7046 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
7048 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
7049 style block comment is no longer considered an error.
7051 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
7053 * PLUGIN/guile.libs.in: New file.
7054 * PLUGIN/guile.libs: Removed from repository.
7055 * configure.in: Create PLUGIN/guile.libs from
7056 PLUGIN/guile.libs.in. This is for including additonal libraries
7057 needed for dynamic linking.
7058 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
7059 instead of PLUGIN/guile.libs.
7061 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
7063 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
7065 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
7066 occurrences of the given element from the list, not just the
7067 first. This is how the Emacs Lisp functions behave, how the
7068 analogous Common Lisp functions behave, and (I believe) how the
7069 older Maclisp functions worked. I realize that this change may
7070 break code, but it seemed better to break it before the Guile
7073 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
7074 Their prototypes were already present in gc.h, but they weren't
7076 (scm_init_storage): Initialize scm_protects.
7077 * root.c (scm_protects): New element of scm_sys_protects.
7079 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
7081 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
7083 * libguile.h: Added #include "libguile/net_db.h".
7085 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
7086 30 change. That file is only meant for communication between the
7087 configuration process and load.c. If code linked against libguile
7088 wants to get at the paths mentioned in libpath.h, it can call
7089 functions declared in load.h.
7091 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7093 * libguile.h: Removed #include "libguile/fdsocket.h"
7095 * net_db.c: Added #include <sys/socket.h>.
7097 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
7099 * filesys.c (scm_input_waiting_p): use select in preference to
7100 FIONREAD, since the latter doesn't detect EOF.
7101 Throw error if neither select nor FIONREAD available.
7103 * socket.c (scm_connect): take a port, not a fd object.
7104 (scm_fill_sockaddr): throw an error if fam is not recognised.
7105 (scm_bind): use scm_fill_sockaddr.
7106 (scm_listen): take a port, not a fd object.
7107 (scm_accept): take and return a port. return #f in the car if
7108 address can't be got
7109 (scm_sock_fd_to_port): new procedure.
7110 (scm_socket): use scm_sock_fd_to_port.
7111 (scm_addr_vector): throw error if unrecognised address type.
7112 take an extra argument with the calling procedure name.
7113 (scm_getsockname): take a port. return #f if address can't be got.
7114 (scm_getpeername): take a port. return #f if address can't be got.
7115 (scm_recvfrom): take a port. return #f for address component if can't
7117 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
7118 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
7120 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
7122 * throw.c (scm_internal_catch): Make body funcs and handler funcs
7123 use separate data pointers, to allow them to be designed
7124 independently and reused.
7125 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
7126 Renamed from catch_body, catch_handler, and uncaught_throw; made
7128 (struct scm_catch_body_data): Renamed from catch_body_data; moved
7130 (scm_catch): Use the above.
7131 (scm_throw): Don't bother printing a message for an uncaught
7132 throw; we establish a default handler in init.
7133 * throw.h (scm_internal_catch): Prototype updated.
7134 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
7136 (struct scm_body_thunk_data): New structure, used as data
7137 argument to scm_body_thunk.
7138 * init.c (struct main_func_closure): New structure, packaging up
7139 the data to pass to the user's main function.
7140 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
7141 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
7142 scm_internal_catch to establish a catch-all handler, using
7143 scm_handle_by_message. This replaces the special-case code in
7145 (invoke_main_func): Body function for scm_internal_catch; invoke
7146 the user's main function, using the main_func_closure pointer to
7147 decide what to pass it.
7148 * root.c (struct cwdr_body_data): Remove handler_proc member.
7149 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
7150 (cwdr_handler): Removed.
7152 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
7154 * socket.h (SCM_P): update bind prototype.
7155 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
7156 include "feature.h".
7157 (scm_socket): return a port, not a file descriptor object.
7158 include "fports.h" and <unistd.h>
7159 (scm_bind): take a port, not a file descriptor object.
7160 take an extra argument for address args.
7162 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
7163 INADDR_NONE, INADDR_LOOPBACK.
7165 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
7167 * init.c: include net_db.h and not fdsocket.h.
7168 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
7170 * Makefile.am: corresponding changes.
7171 * socket.h: renamed from fdsocket.h, fix names.
7172 * net_db.h: renamed from socket.h, fix names.
7173 * socket.c: renamed from fdsocket.c.
7174 remove _sys from procedure names.
7175 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
7176 add "socket" to features list.
7177 * net_db.c: renamed from socket.c.
7178 remove _sys from procedure names.
7179 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
7180 add "net-db" to features list.
7181 include "net_db.h". don't include <sys/socket.h> or
7184 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7186 * tags.h (scm_tags): Removed comma at end of last enumerator.
7188 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
7190 Don't use GCC extensions to allocate space for debugging frames.
7191 (Here he goes again! Why do we put up with this?!)
7192 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
7193 an scm_debug_info structure, not an in-line array of them. Add
7194 'info' member, to say how many vect elements we've used, for eval
7196 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
7197 a new variable debug_info_end to mark the end of vect, instead of
7198 the address of the 'info' pointer itself.
7199 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
7200 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
7201 (SCM_APPLY): Explicitly allocate space for debug.vect.
7202 * debug.c (scm_m_start_stack): Same, for vframe.vect.
7203 * stacks.c: Adjusted for new debug frame structure.
7204 (RELOC_INFO, RELOC_FRAME): New macros.
7205 (stack_depth, read_frames): Use them, and new scm_debug_frame
7206 element 'info', instead of magically knowing that eval frames have
7207 an info pointer sitting after vect.
7208 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
7210 (scm_init_stacks): Formatting tweaks.
7212 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
7214 Give GCC more control flow information, so it can be sure that
7215 variables aren't used uninitialized.
7216 * error.h (scm_error, scm_syserror, scm_syserror_msg,
7217 scm_sysmissing, scm_num_overflow, scm_out_of_range,
7218 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
7219 scm_misc_error): Tell GCC that these functions never return.
7220 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
7221 out the field type, call abort if SCM_ASSERT returns, to placate
7223 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
7224 scm_wta ever returns. We can't handle this case anyway, and this
7225 gives the optimizer more information.
7226 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
7227 scm_wta ever returns.
7229 In some cases, the code is fine, but GCC isn't smart enough to
7230 figure that out; this usually happens when one variable is only
7231 initialized and used when a particular condition holds true, and
7232 we know that condition will never change within a given invocation
7233 of the function. In this case, we simply initialize the variables
7234 to placate the compiler, hopefully to a value which will cause a
7235 crash if it is ever actually used.
7236 * print.c (scm_iprin1): Initialize mw_pos.
7237 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
7238 * throw.c (scm_ithrow): Initialize dynpair.
7239 * unif.c (scm_uniform_vector_ref): Initialize cra.
7240 * struct.c (init_struct): Initialize prot.
7241 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
7243 * strports.c (scm_eval_0str): Don't return uninitialized garbage
7244 if EXPR contains no expressions.
7246 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
7248 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
7249 cause an infinite loop (???). So much for the algebraic
7250 equivalency of variable-sized arrays and alloca...
7252 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
7254 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
7255 a SCM boolean, not a C boolean.
7257 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
7259 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
7260 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
7261 rules for raising scm_mtrigger. Previously, unfortunate but not
7262 unlikely circumstances could result in almost constant invokation
7263 of the gc. Now, this situations should be less likely, but they
7264 are not prevented completely.
7266 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
7268 * numbers.c (scm_fuck): Procedure removed; looks like old test
7270 * numbers.h: Prototype removed.
7272 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
7274 * debug.h (scm_debug_frame): Change `vect' member from an in-line
7275 array to a pointer, to match my Nov 21 change in eval.c.
7277 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7279 * libguile.h: Added #include "libguile/backtrace.h", #include
7280 "libguile/stacks.h".
7282 * strings.c (scm_string scm_make_string scm_string_ref
7283 scm_string_set_x scm_string_equal_p scm_string_append):
7284 Bugfix according to scm patch from Aubrey Jaffer:
7285 Corrected long-standing
7286 (not (eqv? (integer->char 128)
7287 (string-ref (make-string 1 (integer->char 128)) 0)))
7288 bug found by John Kozak <jk@noontide.demon.co.uk>.
7290 * strports.c, strports.h: Make scm_eval_0str return the value of
7291 the last expression evaluated (previously, it returned void).
7293 * strports.c, strports.h: New function: scm_read_0str. Does what
7296 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7298 * simpos.c (scm_getenv): return #f if string can't be found in the
7299 environment instead of throwing an exception, for compatibility
7300 with numerous other systems.
7302 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
7304 * Makefile.am (.c.x): Use guile-snarf.
7305 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
7307 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
7309 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
7311 * backtrace.c (scm_display_error_message): Made non-static, and
7312 renamed from display_error_message.
7313 * backtrace.h (scm_display_error_message): Added extern decl.
7314 * throw.c (uncaught_throw): Use it to display the error message.
7316 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
7318 * inet_aton.c: Use #if 0, not #ifdef 0.
7320 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
7322 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
7323 to convert the returned value.
7324 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
7325 the offset argument.
7327 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
7329 Add new interface to catch/throw, usable from C as well as
7331 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
7332 (scm_internal_catch): New function, replaces...
7333 (scm_catch_apply): Deleted.
7334 * throw.c (scm_catch_apply): Deleted; replaced with a more general
7335 mechanism which is a bit more code, but can be used nicely from C
7336 and implement the Scheme semantics as well.
7337 (scm_internal_catch): This is the replacement; it's named after
7338 the analogous function in Emacs.
7339 (scm_catch): Reimplemented in terms of the above.
7340 (struct catch_body_data, catch_body, catch_handler): New
7341 functions, used by scm_catch.
7342 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
7343 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
7344 support for new cwdr.
7346 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
7349 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
7351 * acconfig.h: Added DYNAMIC_LINKING symbol.
7352 * configure.in: Add option and checks for dynamic linking.
7353 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
7354 dynl.h: New files for dynamic linking support.
7355 * Makefile.am (libguile_a_SOURCES):
7357 (modinclude_HEADERS): Added "dynl.h".
7358 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
7360 * init.c (scm_boot_guile_1): Call
7361 scm_init_dynamic_linking to initialize dynamic linking support.
7363 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
7365 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
7366 (as we Schemers say). It needs to be global, so that I can tweak
7367 it for the proper operation of unexec.
7368 (scm_boot_guile_1_live): New variable, see above.
7370 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
7372 * guile-snarf.sh: Removed.
7373 * PLUGIN/guile.libs: Added dependency for -lm.
7374 * acinclude.m4: Renamed from aclocal.m4.
7375 * PLUGIN/greet: Removed.
7376 * Makefile.am, aclocal.m4: New files.
7377 * configure.in: Updated for Automake.
7379 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
7381 * eval.c (scm_definedp): Use top_level_lookup_closure_var
7382 and not top_level_lookup_thunk_var.
7384 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
7386 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
7388 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
7390 * eval.c (scm_definedp): Incompatibly changed to be a builtin
7391 Scheme function, instead of syntax. Single argument is now a
7394 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7396 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
7397 scm_ra_divide): Properly terminate statements passed as arguments
7398 to IVDEP macros. (Thanks to Bernard Urban.)
7400 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
7401 with non-constant sizes. (Thanks to Bernard Urban.)
7403 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
7405 It's an "eval closure", not an "eval thunk." A thunk is a
7406 function of no arguments.
7407 * root.h (struct scm_root_state): Renamed
7408 top_level_lookup_closure_var from top_level_lookup_thunk_var.
7409 (scm_top_level_lookup_closure_var): Renamed from
7410 scm_top_level_lookup_thunk_var.
7411 * root.c (mark_root): Uses changed.
7412 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
7413 * init.c (scm_start_stack): Uses changed.
7414 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
7415 Change scheme-visible name to *top-level-lookup-closure* from
7416 *top-level-lookup-thunk*.
7418 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
7420 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
7421 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
7423 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
7425 * gc.c (struct scm_heap_seg_data): Doc fixes.
7427 * gc.c (scm_gc_sweep): Empty all segments' freelists before
7428 sweeping. Then, prepend each segment's free cells to its
7429 freelist, rather than wiping out the old value. (Thanks to Marius
7432 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
7433 scm_check_freelist, scm_debug_newcell): New functions and
7434 variables, for debugging freelist problems.
7435 * pairs.h (SCM_NEWCELL): New debugging version added.
7436 * gc.h (scm_debug_newcell): Added extern declaration, used by
7437 debugging version of SCM_NEWCELL.
7439 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7441 On some systems <libc.h> conflicts with <unistd.h>, and should not
7442 be #included at all.
7443 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
7444 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
7445 * configure.in: Call it.
7446 * posix.c, filesys.c: Use its results to decide whether or not to
7448 * configure, scmconfig.h.in: Rebuilt with autoconf and
7451 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7453 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
7454 pointer to the stdio stream before calling scm_setbuf0, so the
7455 latter will be able to retrieve it. I'm surprised this didn't
7456 segfault earlier. (Thanks to Christopher Lee.)
7458 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7460 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
7463 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7465 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
7466 number of stack narrowing specifier pairs. The first specifier in
7467 a pair controls inner border, the second the outer border. A
7468 number means cut that number of frames, a procedure object means
7469 cut until that object is found in operator position in a frame.
7471 * root.c (cwdr): Bugfix.
7473 * read.c: Recording of positions disabled by default.
7475 * procs.c (scm_closure_p): New function.
7477 * posix.c (scm_tmpnam): New function.
7479 * load.c: Added #include "throw.h".
7480 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
7483 * load.c, load.h (scm_read_and_eval_x): New function.
7485 * eval.c: Renamed debug option "deval" to "debug".
7487 (scm_eval_x): `eval!' is no longer accessible from the scheme
7488 level. Motivation: We can't allow operations which introduce
7489 glocs into the scheme level. Guile's type system can't handle
7490 these as data. Use `eval' or `read-and-eval!' as replacement.
7492 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
7493 SCM_CONSP since this is a macro!; Set vframe.prev to
7494 scm_last_debug_frame instead of 0. In this way we can look
7495 "above" the virtual start stack frame if we wish.
7496 (scm_debug_hang): New function: Useful for debugging Guile in
7497 certain tricky situations. Will probably be removed later...
7499 * debug.h: Changed semantics of debug option "backtrace". This
7500 option now only indicates whether we want automatic backtrace at
7503 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7505 * ports.c: #include "filesys.h"
7506 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
7508 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
7509 Motivation: This is system specific code which is related to file
7510 I/O. It also may use select. Added code by Gary Houston to
7511 detect presence of character in stdio buffers.
7513 * libguile.h: #include "libguile/libpath.h"
7515 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
7516 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
7517 SCM_SITE_DIR; Install libpath.h among the other include files.
7519 * load.c, load.h (scm_sys_package_data_dir): New function.
7521 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7523 * stacks.h: Bugfix: Don't use tail-array length field as stack
7524 length field! This screwed GC.
7526 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7528 * _scm.h: Added #ifndef around definition of macros min and max.
7530 * __scm.h: Added hooks for threads to plugin to in ints protection
7531 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
7532 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
7533 the main code in these macros duplicated and spread over multiple
7534 files. Renamed SCM_THREADS_SWITCHING_CODE ->
7535 SCM_THREAD_SWITCHING_CODE.
7537 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
7539 * snarf.h: New file.
7540 * guile-snarf.sh: New file.
7541 * Makefile.in (inner_h_files): Added snarf.h
7542 (ancillary, install, uninstall, distclean): Added actions for
7544 (.c.x): Use guile-snarf.
7545 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
7546 (gen_c_files): Note that these depend on guile-snarf.
7547 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
7548 now in "snarf.h". Added #include "snarf.h" to get them.
7549 * libguile.h: Added #include "snarf.h".
7550 (Patches applied and tweaked by Jim Blandy.)
7552 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7554 * socket.c: Use K&R style declaration for 'close'; the GNU coding
7555 standards suggest against providing prototypes for system
7556 functions. Thanks to Greg Troxel.
7558 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
7560 * strports.c (scm_eval_0str): New function.
7561 #include "read.h", to get prototype for scm_read.
7562 * Makefile.in (strports.o): Update dependencies.
7563 * strports.h: New prototype.
7565 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
7566 scheme name from "int?" to "integer?". It seems to do the job.
7567 * numbers.h: Rename prototype too.
7568 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
7571 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
7572 scm_num_eq_p): Rename these according to R4RS conventions: call
7573 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
7574 to making libguile R4RS compliant without ice-9...
7576 * load.c (scm_sys_search_load_path): Search for files under all
7577 extensions listed in the %load-extensions variable. If FILENAME
7578 is absolute, return it unchanged, without searching the load path.
7579 (scm_loc_load_extensions): New variable, pointing to
7580 %load-extensions' value cell.
7581 (scm_init_load): Initialize it, and the value it points to.
7582 (scm_primitive_load_path): Improve error reporting.
7584 * load.c (scm_loc_load_hook): New variable, pointing to value cell
7585 of new Scheme variable %load-hook.
7586 (scm_primitive_load): Apply %load-hook to filename.
7588 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
7590 * configure.in: add tests for figuring out whether buffered data
7591 is available in a FILE structure, which is needed by char-ready.
7593 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
7596 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
7597 exceptions using misc_error instead of syserror. It seems a bit
7598 odd to throw an exception if a string can't be found in the
7599 environment, but it's consistent with open-file, stat etc.
7600 (simpos.h): remove sys_ from getenv.
7602 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
7603 occurs, throw an error instead of returning errno. Return value
7605 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
7607 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
7609 * filesys.c (scm_stat2scm): derive file type and permissions from
7610 the stat mode and append them to the returned vector.
7611 There isn't much overhead in doing this and it avoids the need to
7612 work with S_IRUSR et al. in Scheme.
7613 Define symbols scm_sym_regular etc.
7614 (scm_init_filesys): don't intern S_IRUSR etc.
7616 * load.c: change s_try_load and s_try_load_path to s_primitive_load
7617 and s_primitive_load_path.
7619 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
7621 * error.h: don't declare error symbols. prototype for scm_misc_error.
7623 * stackchk.c (scm_stack_overflow_key): defined here instead of in
7626 * error.c: use SCM_SYMBOL to set up error keys.
7627 scm_misc_error: new procedure.
7629 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
7631 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
7632 between `#!' and `!#' is ignored.
7633 (skip_scsh_block_comment): New function.
7635 * feature.c (scm_set_program_arguments): New argument, FIRST.
7636 * feature.h: Update prototype.
7637 * init.c (scm_boot_guile_1): Pass new argument to
7638 scm_set_program_arguments.
7640 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
7642 * init.c (scm_start_stack): Don't initialize scm_progargs here.
7643 (scm_boot_guile): Call scm_set_program_arguments here, later than
7644 the old initialization.
7646 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
7647 initialization procedure.
7648 - Delete in, out, err arguments; there are other perfectly good
7649 ways to override these when desired.
7650 - Delete result argument; this function shouldn't ever return.
7651 - Rename init_func argument to main_func, for less confusion.
7652 - Delete boot_cmd argument; main_func is more general.
7653 -Add 'closure' argument, to help people pass data to main_func
7654 without resorting to global variables.
7655 - Abort if reentered; don't bother returning an error code.
7656 - Call scm_init_standard_ports to set up the default/current
7657 standard ports; no need to pass them to scm_start_stack.
7658 - Remove code to evaluate the boot_cmd, and start the repl; let
7659 the user do something like that in main_func if they want.
7660 - Remove code to package up a return value; main_func can do any
7662 - Call exit (0), instead of returning.
7663 (scm_start_stack): Don't initialize the I/O ports here; that's
7664 weird. Delete in, out, err arguments. Move guts to
7665 scm_init_standard_ports, scm_stdio_to_port.
7666 (scm_init_standard_ports): New function, to set up current and
7667 default standard ports.
7668 (scm_start_stack, scm_restart_stack): Make these static.
7669 * init.h (scm_boot_guile): Adjust declaration.
7670 (scm_start_stack, scm_restart_stack): Remove externally
7671 visible declarations for these.
7672 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
7674 * fports.c (scm_stdio_to_port): New function. Its guts used to be
7675 written out several times in scm_start_stack.
7676 * fports.h: New declaration for the above.
7678 * feature.c (scm_set_program_arguments): New function.
7679 * feature.h: New declaration for the above.
7681 * ports.c: Formatting tweak.
7683 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
7685 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
7686 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
7687 for obtaining the address of a car or cdr field. Motivation:
7688 &SCM_CXR make assumptions about the internal structure of the
7691 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
7692 Motivation: see SCM_CXRLOC.
7694 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
7695 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
7696 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
7697 Motivation: Safer use. Some other macros are defined in terms of
7698 these operations. If these are defined using the SCM_SETCXR
7699 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
7700 to inefficiency and an <e1> with side-effects could potentially
7701 break. Also, these particular operations are heavily utilized in
7702 the garbage collector. In unoptimized code there will be a
7705 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
7706 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
7707 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
7708 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
7709 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
7710 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
7711 vports.c: Cleaned up use of pairs: Don't make any special
7712 assumptions about the internal structure of selectors and
7713 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
7714 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
7715 (Among other things, this change makes it easier to build Guile
7716 with certain compilers which have problems with casted lvalues.)
7718 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7720 * stacks.c: Improve selection of relevant stack frames when making
7721 a stack object. Introduce one level of indirection in the stack
7722 object to make it possible to "narrow" to a certain region of the
7723 stack. This facilitates making use of more clever algorithms (not
7724 implemented) for selecting relevant frames and gives a cleaner
7725 design since selection of frames can be done independently of
7726 extraction of frames from the real stack.
7727 (scm_stack_id): Also take #t as argument which means look at
7730 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
7731 Turn n_tail into an integer directly representing current number
7732 of frames in stack. Add field tail.
7734 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
7736 * debug.c (scm_make_memoized): Made it available at scheme level.
7737 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
7738 SCM_NIMP before applying heavier predicates in argument checking.
7739 (scm_local_eval): Also take memoized object as argument.
7741 * backtrace.c (scm_display_error): Just a safety measure: Stacks
7742 aren't created with zero length, but should such a strange
7743 creature suddenly turn up...
7745 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
7747 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
7748 `del', for the sake of C++ compilers. (Patch applied by JimB.)
7750 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
7752 * variable.c (scm_make_variable): Make the name hint optional, as
7754 (anonymous_variable_sym): Renamed from variable_sym. All uses
7757 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
7758 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
7759 of scm_primitive_load_path was also changed to
7760 "primitive-load-path", from "%try-load-path". Callers changed.
7761 We'd like to respect the convention that a function named
7762 "try-mumble" should behave just like the function called "mumble",
7763 but return #f instead of signalling some error.
7764 * load.h: Rename prototypes.
7766 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7768 * print.c (make_print_state, grow_print_state), print.h: Modified
7769 the print state representation: Don't use a tail array for
7770 recording of circular references. Resizing of the print state
7771 structure invalidates the print state pointer. To avoid passing
7772 around an indirect print state reference to all printing
7773 functions, we instead let the print state reference a resizable
7776 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7778 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
7779 Don't crash when passed an improper list terminated by a
7780 non-immediate value.
7782 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
7784 Allocate data for structures on an eight-byte boundary, as
7785 required by the tagging system.
7786 * struct.c (alloc_struct): New function.
7787 (scm_make_struct, scm_make_vtable_vtable): Call it.
7788 * struct.h (scm_struct_n_extra_words): Bump to 3.
7789 (scm_struct_i_ptr): New "field".
7790 * gc.c (scm_gc_sweep): When we need to free the data, use the
7791 information stored by alloc_struct to find the beginning of the
7792 block allocated to the structure, so we can free it.
7794 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7796 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
7799 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
7800 (scm_debug_info): New member: id.
7802 * stacks.c: Stacks are now represented as structs; Stacks have an
7803 id given to them by `start-stack'.
7804 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
7806 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
7807 Changed stack representation.
7809 * debug.c (scm_procedure_name): Try procedure property `name' for
7810 compiled closures aswell.
7812 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
7814 * eval.c: scm_i_name moved to gsubr.c
7815 (scm_m_define): Record names of all kinds of procedure
7816 objects. (Earlier, only closures were recorded.)
7818 * procprop.h: Added declaration of scm_i_name.
7820 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
7821 (scm_make_gsubr): Record names of compiled closures.
7823 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7825 * debug.c, debug.h: Removed obsolete code.
7827 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
7828 stacks.c: Renamed regs --> scm_contregs.
7830 * print.c (scm_free_print_state): Cleanup print state before
7831 returning it to pool. It is better to do it here than in
7832 scm_prin1 since scm_prin1 is called often.
7834 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
7835 s_set_source_property_x): Check that first argument is a pair or a
7838 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
7839 scm_i_line, scm_i_column and scm_i_breakpoint global.
7841 * init.c: Added #include "backtrace.h" and #include "stacks.h".
7842 (scm_boot_guile_1): Added calls to scm_init_backtrace and
7845 * debug.h: Added debug object smob declaration and macro
7848 * configure.in: Build with backtrace.o and stacks.o if debug
7851 * Makefile.in: Added entries for new files: backtrace.c,
7852 backtrace.h, stacks.c and stacks.h.
7854 * symbols.c (scm_sym2ovcell): Fixed documentation.
7856 * _scm.h (min, max): Added.
7858 * async.c: Moved `min' macro to _scm.h.
7860 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
7861 SCM_BACKTRACE_INDENT.
7863 * eval.c: Added new debug options `maxdepth' and `indent'.
7865 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
7867 * print.h: Added selector SCM_PRINT_STATE.
7869 * print.c: New functions: scm_make_print_state,
7870 scm_free_print_state.
7872 * print.h: Added declarations for scm_make_print_state,
7873 scm_free_print_state.
7875 * debug.c (scm_m_start_stack): New acro.
7877 * debug.h: Small cleanup.
7879 * init.c (scm_boot_guile_1): Moved scm_init_debug below

7907 More prototype-related changes from Marius Vollmer:
7908 * gdb_interface.h: Wrapped header file in #ifdef/#endif
7909 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
7910 * ports.h (ptobfuns): Added prototypes. This means some casting in
7912 * fports.c: Added casts for initializations, since the functions
7913 are defined to take FILE * as their stream argument, not SCM.
7914 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
7915 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
7916 to `char *str_data' to conform to prototype.
7918 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7920 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
7922 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
7924 * stime.c, stime.h: use SCM_P method.
7926 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7928 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
7929 be given at least two arguments. Insist that lst's last element
7930 be a list, but don't make any requirements of its predecessors.
7932 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7934 * eval.c (scm_nconc2last): Revert last change; there seems to be
7935 other stuff going on here.
7937 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7939 * eval.c (scm_nconc2last): Make sure that each element of lst
7940 (which is a list of argument lists, except for the tail) is a
7941 proper list, i.e., finite and terminated by '().
7943 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7945 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7948 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7949 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7952 * vectors.c (scm_make_vector): Fill vectors with the undefined
7953 value, to help make Guile Scheme code more portable to other
7956 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7957 * symbols.h, tags.h: Doc fixes.
7959 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
7961 * async.c (scm_take_signal): Doc fixes.
7963 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
7965 * numbers.c (scm_divbigint): When the remainder is zero, we don't
7966 want to subtract it from the modulus; we just want to leave it
7969 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
7971 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
7974 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
7976 * throw.c (scm_catch_apply): Finished implementation of
7979 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7981 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
7983 (scm_init_filesys): set "i/o-extensions" feature.
7986 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
7988 * Makefile.in (root.o): Correct dependencies.
7990 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
7992 * Makefile.in: Added dependency entry for root.o.
7994 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
7995 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
7997 * init.c (scm_start_stack): Set initial root continuation number
8000 * procs.c: New function: scm_thunk_p.
8002 * procs.h: Added declarations of scm_thunk_p.
8004 * root.c: Renamed `call-with-new-root' -->
8005 `call-with-dynamic-root'.
8006 (cwdr): Removed allocation of new root state. This should be done
8007 separately by use of scm_make_root.
8008 (scm_apply_with_dynamic_root): New function: Does what it
8009 sounds like. Needed when spawning threads.
8011 * root.h: Added member last_debug_frame to root state.
8012 Added #include "libguile/debug.h"
8014 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
8015 arguments. The motivation is that code in root.c needs catch
8016 functionality, and we want to avoid code duplication.
8017 New functions: scm_catch, scm_lazy_catch. These are wrappers for
8018 scm_catch_apply. scm_lazy_catch is intended to introduce catch
8019 handlers that run without popping the stack into the dynwind
8022 * throw.h: Added prototypes for scm_catch_apply and
8025 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8027 * root.h (scm_root, scm_set_root): Decouple thread support details
8028 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
8029 SCM_SET_THREAD_LOCAL_DATA.
8031 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
8032 and tortoise scanning loop.
8034 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
8036 * Makefile.in: Rebuild dependencies.
8038 * libguile.h: #include "libguile/print.h" before "smob.h", since
8039 the latter uses the print_state structure.
8041 * throw.c (scm_ithrow): Use the correct variable when checking to
8042 see if a given element of scm_dynwinds is a valid catch.
8044 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
8045 structure, abort; don't just silently ignore the garbage.
8047 * _scm.h: #include "print.h" here, since it seems to be used just
8049 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
8050 strports.c, unif.h: Don't #include "print.h".
8052 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8054 * feature.h (scm_loc_features): Removed external declaration.
8055 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
8057 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8059 * feature.c (scm_init_feature): Added threads feature (needs to be
8060 initialized here, since features doesn't exist when
8061 scm_init_threads is called).
8063 * libguile.h: Added #include "libguile/../threads/threads.h".
8064 (This is a kludge to get thread support working. This should be
8067 * configure.in, acconfig.h: Added flags for thread support.
8069 * scmsigs.c: Define `signal' to be `pthread_signal' if using
8072 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
8073 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
8076 * _scm.h: Added conditional #include "threads.h"
8078 * __scm.h (SCM_ASYNC_TICK): Added call to macro
8079 SCM_THREADS_SWITCHING_CODE.
8081 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
8082 allocate the basic dynamic root object.
8083 (scm_boot_guile): Added call to scm_init_root.
8085 * root.c, root.h: Added root smob.
8086 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
8087 functions: Implements dynamic roots mostly according to spec in
8088 SCM manual. Main difference is that the second argument is a
8089 throw handler rather than an error "thunk".
8091 * root.h: Added declaration of scm_init_root.
8093 * root.c: Added #include "genio.h", #include "smob.h", #include
8094 "pairs.h", #include "throw.h", #include "dynwind.h", #include
8096 (scm_init_root): Added #include "root.x".
8098 * throw.c: Added #include "stackchk.h"
8099 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
8100 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
8101 can be used in scm_call_with_new_root; Added reenabling of stack
8102 checking when catching a throw.
8104 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
8106 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
8108 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
8109 element is not found, as per R4RS.
8111 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
8113 * list.c: Doc fixes throughout.
8115 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
8117 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
8118 declare the char * to be const. Avoids a warning in rgx.c.
8120 * ports.h: spelling fix.
8122 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
8125 * load.c (scm_sys_try_load_path): throw an error if file not found
8126 (like it says it in NEWS).
8128 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
8130 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
8131 PROPS slot to '(), not #f; it's an empty alist.
8133 * throw.h, throw.c: Use SCM_P instead of #if hair.
8135 Remove special support for uncaught throws; see throw.c for
8137 * throw.c (uncaught_throw): New function.
8138 (scm_ithrow): Call uncaught_throw if we don't find a throw
8139 target; don't mess with scm_bad_throw_vcell.
8140 (scm_bad_throw_vcell): Variable deleted.
8141 (scm_init_throw): Don't initialize it.
8143 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
8146 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
8148 * numbers.c (scm_istr2int): If the number is short (as most
8149 numbers are), just call scm_small_istr2int to deal with it.
8150 (scm_small_istr2int): New function, created by un-#ifdefing the
8151 non-bignum version of scm_istr2int and renaming it.
8153 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
8155 * load.c (scm_sys_try_load): don't check whether value returned
8156 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
8157 Change the Scheme name from %try-load to primitive-load.
8159 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
8160 Can avoid passing a message, allowing it to be derived in the
8161 error handler (e.g., if we want to throw to the key both from
8164 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
8166 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
8167 references now have a new appearance which is more compact and
8168 also gives a clue about what the target of the reference is.
8169 By setting parameters in the print state, more fancy printing can
8170 be achieved. This is used by the (not yet commited) backtrace
8173 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
8175 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
8178 * print.c: Added #include "struct.h". Removed function
8181 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
8182 scm_iprin1. Removed prototype for scm_prlist.
8184 * arbiters.c (prinarb),
8185 async.c (print_async),
8186 debug.c (prindebugobj, prinmemoized),
8187 eval.c (prinprom, prinmacro),
8188 filesys.c (scm_fd_print, scm_dir_print),
8190 mallocs.c (prinmalloc),
8191 numbers.c, numbers.h (scm_floprint, scm_bigprint),
8192 smob.h (scm_smobfuns),
8193 srcprop.c (prinsrcprops),
8195 unif.c, unif.h (scm_raprin1, rapr1),
8196 variable.c (prin_var): Changed argument `int writing' to
8197 `scm_print_state *pstate'.
8199 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
8200 that it will be called before scm_init_print.
8202 * print.c (scm_prin1): Print states are now allocated when calling
8203 scm_prin1 and then passed around to all printing functions as an
8204 argument. A cache `print_state_pool' enables reuse of print
8206 (scm_make_print_state): New function.
8207 (scm_iprin1): Adaption to print states.
8208 (scm_iprlist): An initial "hare and tortoise" scan brings down
8209 time complexity to O (depth * N). (Better time complexity will be
8210 achieved when the printing code is completely rewritten.)
8212 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
8214 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
8215 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
8216 it gets done whether or not the cache variable has a value.
8218 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8220 Distinguish #f and ().
8221 * __scm.h: #undef SICP.
8222 * pairs.h (SCM_EOL): Delete this definition, equating it with
8224 * tags.h (SCM_EOL): Give it a new definition here; I think I found
8225 the value it used to have. Doc fixes, too.
8227 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
8229 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
8230 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
8231 Lord's implementation of structs, allowing for tail arrays as
8232 described in the manual. Also fixed some bugs. (Both the interface
8233 and the implementation should be improved.)
8235 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
8237 * print.c, print.h: Closures now print like #<procedure foo (x)>.
8238 People who whish to see the source can do `(print-enable 'source)'.
8239 Removed #ifdef DEBUG_EXTENSIONS.
8241 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
8243 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
8244 integer (assuming for now accepting an integer is a good thing).
8246 * error.c, fports.c: replace use of %S in lgh_error args with %s.
8247 %S will be used instead for write'ing arguments.
8249 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
8250 asserts. fix a few other asserts.
8251 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
8252 scm_uniform_vector_ref, scm_array_set_x,
8253 scm_dimensions_to_unform_array): change args in
8254 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
8255 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
8256 scm_substring_fill_x): likewise.
8257 gsubr.c (scm_gsubr_apply): likewise.
8258 eval.c (SCM_APPLY): likewise.
8260 * eval.c (4 places): replace scm_everr with lgh_error or
8263 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
8264 scm_memory_error): new procedures.
8265 scm_everr: deleted. can use scm_wta, dropping first two args.
8266 scm_error: convert NULL subr to SCM_BOOL_F.
8268 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
8271 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
8274 * error.c, error.h: new error keys: scm_arg_type_key,
8275 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
8277 scm_wta: reimplement using lgh_error instead of scm_everr.
8279 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
8281 * gdbint.c: scm_lread now has one more argument.
8283 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
8284 scm_port_\1; Added mutator scm_set_port_filename_x (used when
8285 loading source from non-file ports, which, e. g., happens when
8286 using the Emacs interface).
8288 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
8291 * read.c: Added code for recording of positions of source code
8292 expressions; New functions: recsexpr, scm_lreadrecparen;
8293 _scm_make_srcprops --> scm_make_srcprops
8294 (scm_flush_ws): Removed updating of positions counters. This work
8295 is already done by scm_gen_getc
8297 * read.h: Added prototype for scm_lreadrecparen
8299 * print.c: Added #include "alist.h"
8301 * eval.c: Added #include "hash.h"
8303 * eq.c: Added #include "ramap.h"
8305 * options.c: Documentation fixes.
8307 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
8308 (scm_init_srcprop): Adjusted size of initial source-whash. Name
8309 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
8310 --> scm_make_srcprops
8312 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
8313 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
8314 function calls in the definition of the whash access macros.
8316 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
8318 * init.c (scm_boot_guile): Add level of indirection to
8319 scm_boot_guile_1() to ensure that stack base pointer is properly
8320 initialized. There was no guarantee that variable i was the
8321 highest/lowest variable on stack (i.e. the call frame of
8322 scm_boot_guile was not completely protected from gc).
8324 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
8326 * ports.h (scm_port_table): put back file_name, it will be used to
8327 support debugging. Undo related changes in fports.c, ioext.c,
8330 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
8332 * ports.h (scm_port_table): remove file_name member for now, it seems
8334 * fports.c (scm_open_file): don't set file_name in PTAB.
8335 (prinfport): don't use file_name in PTAB.
8336 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
8337 * ports.c (scm_add_to_port_table): don't intialize file_name.
8338 (scm_port_file_name): remove for now.
8339 * gc.c (scm_gc_mark): don't mark PTAB file_name.
8341 * fports.h (scm_mkfile): prototype deleted.
8342 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
8344 * debug.c, unif.c: use scm_out_of_range instead of
8345 wta for range errors (ASSERT still needs work).
8347 * error.c, error.h (scm_out_of_range): new procedure.
8349 * error.c, error.h (scm_out_of_range_key): new key.
8351 * posix.c (scm_sync): #else was missing.
8353 * error.c, error.h: append _key to names scm_num_overflow and
8356 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
8357 of consing an empty list.
8358 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
8359 of macros, saves code and string space.
8360 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
8361 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
8362 lower case. Rename scm_syserror_m to scm_syserror_msg.
8363 error.h: prototypes for new procedures.
8365 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
8367 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
8369 * error.c, error.h: setup scm_num_overflow key.
8371 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
8372 Remove definition of SCM_OVSCM_FLOW.
8374 * fports.c (scm_open_file): use SCM_SYSERROR_M.
8376 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
8377 explicit message and args.
8379 * error.c, error.h, __scm.h: change system_error_sym to
8382 * error.c (system_error_sym): remove leading %% from the Scheme name
8385 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
8387 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8389 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
8390 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
8391 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
8392 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
8393 renamed. (These were introduced by unsupervised name
8396 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8398 * print.c: Added code for detection of circular references during
8399 printing. (init_ref_stack, grow_ref_stack): New functions. Added
8400 a hook for printing of closures (accessible via print options).
8401 This leads to a split of calls to scm_iprin1 into two classes:
8402 elementary print operations (e. g. the code which prints a smob)
8403 still use scm_iprin1 while top level calls (like scm_display) use
8404 scm_prin1. scm_prin1 begins by clearing the data structure used
8405 to record reference information.
8407 * print.h: Added declarations of scm_prin1 and scm_prlist.
8409 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
8411 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
8413 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
8415 * error.c (err_head): scm_iprin1 --> scm_prin1
8417 * debug.c: Adjusted header comment.
8421 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
8423 * strerror.c: Doc fix.
8425 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8427 * gdbint.c (gdb_read): Now possible to run during GC.
8428 (unmark_port, remark_port): New functions.
8430 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
8432 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
8433 of allocating a new string object. Also, increase size by
8434 the factor 2 instead of 1.5.
8436 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
8438 * __scm.h (SCM_P): Corrected to run under traditional C.
8440 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
8443 * async.c: Calls to scm_sysintern corrected.
8445 * async.h (scm_async_clock): Redundant declaration removed.
8447 * continuations.c (scm_dynthrow): Redundant declaration removed.
8449 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
8450 Definition typos corrected.
8452 * debug.h: Missing declarations of functions in debug.c added
8455 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
8456 Missing declarations to functions in eval.c added.
8458 * filesys.c: Possibly uninitialized variable rv.
8460 * gc.h (scm_object_addr, scm_unhash_name): Missing
8461 declarations of functions defined in gc.c added.
8463 * genio.c: Possible typos str_data -> wstr_data. ???
8465 * genio.c: Possibly unintended shadowing of local variable
8466 `int c' (gotos out of scope of inner `c'). ???
8468 * init.c: Uninitialized `SCM last' may be used.
8470 * ioext.h: (scm_sys_isatty_p): Typo.
8472 * list.h (scm_list_head): Missing prototype for function in
8475 * numbers.c (scm_two_doubles): Changed from extern to static
8476 (is used only within numbers.c).
8478 * numbers.h: Repeated declarations removed.
8480 * ports.h (scm_close_all_ports_except): Declaration for the
8481 function defined in ports.c added.
8483 * posix.h: Missing declarations added.
8485 * procs.h (scm_make_subr_opt): Missing declaration added.
8487 * socket.h (scm_sys_gethost): Missing declaration added.
8489 * socket.h: Redundant declarations removed (they are in fdsocket.h).
8491 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
8492 Missing declarations added.
8494 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
8496 * struct.c: Uninitialized variable `SCM answer' may be used.
8498 * unif.c (l2ra): Declaration prototype.
8500 * unif.c (scm_array_equal_p): Dummy definition removed (it is
8501 defined in ramap.c).
8503 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
8504 Redundant declarations removed (they are in ramap.h).
8506 * variable.h (scm_make_udvariable,
8507 scm_make_undefined_variable): Declaration corrected to
8508 correspond variable.c.
8510 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
8511 Missing declarations added.
8513 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
8515 * Makefile.in (distclean): Don't forget to delete fd.h.
8517 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
8519 * fd.h.in, tags.h: Trivial cleanups.
8521 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
8522 marksweep.h just declared functions from gc.c.
8523 * gc.h, libguile.h: Don't #include "marksweep.h".
8524 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
8525 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
8526 dependencies updated.
8528 * libguile.h: Don't #include "files.h"; it's been deleted.
8530 * files.c (scm_sys_delete_file): Moved to filesys.c.
8531 File is now empty; deleted.
8533 * filesys.c: scm_sys_delete_file is now here. Remove
8534 #if's; they seem to rely on remnants of an old portability
8535 regimen. If the problems come up again, solve them properly,
8536 using autoconf. Specifically: Don't test M_SYSV, and #define
8537 remove to be unlink if it's #defined; don't use remove just
8538 because HAVE_STDC_HEADERS is #defined.
8539 * filesys.h: Add declarations for scm_sys_delete_file.
8540 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
8541 files.o, files.h, files.c, and files.x.
8542 * init.c: Don't #include "files.h", and don't call scm_init_files.
8544 Use SCM_P instead of PROTO; the latter intrudes on the user's
8546 * params.h: Deleted; definition of SCM_P moved to...
8547 * __scm.h: ... here, where it replaces PROTO macro.
8548 * libguile.h, smob.h: Don't #include "params.h".
8549 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
8550 smob.h: Fix prototypes accordingly.
8551 * Makefile.in: Update dependencies.
8552 (inner_h_files): Remove params.h.
8554 * gc.c: #include "gc.h"; every module should include its header,
8555 to let the compiler cross-check the declarations against the
8558 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
8559 simpos.h: #include "libguile/__scm.h".
8561 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
8563 * init.c: Don't forget to #include smob.h and init.h.
8564 * Makefile.in: Dependencies updated.
8566 * smob.h: Use PROTO instead of #if __STDC__.
8568 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
8570 * __scm.h: Doc fixes.
8572 * __scm.h, libguile.h: Use "quotes" in the #includes, not
8573 <angles>; this allows `make depends' to work properly.
8575 * libguile.h: #include smob.h and pairs.h before the others; they
8576 define typedefs used by other headers.
8578 C files should #include only the header files they need, not
8579 libguile.h (which #includes all the header files); the pointless
8580 recompilation was wasting my time.
8581 * Makefile.in (all .o dependency lists): Regenerated.
8582 * libguile.h: Don't try to get a definition for size_t here...
8583 * __scm.h: Do it here.
8584 * _scm.h: Since this is the internal libguile header, put things
8585 here that all (or a majority) of the libguile files will want.
8586 Don't #include <libguile.h> here; that generates dependencies on
8587 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
8588 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
8589 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

8686 * weaks.c: Get "weaks.h".
8688 * stackchk.h: #include "libguile/debug.h",
8690 * print.h, read.h: #include "options.h", since everyone who uses
8691 either of these files will need that.
8693 * smob.h: #include "ports.h", "genio.h", and "print.h", since
8694 anyone who uses this file will need them to define the smob
8695 printing functions. Also, get markers.h, since people will need
8696 to #define the mark functions.
8698 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
8699 * ports.h: ... to here.
8701 * ports.h (scm_port_table_size): Explicitly give type as 'int';
8702 don't rely on archaic C default type rules.
8704 * fports.h: #include "libguile/ports.h", since you need that in
8705 order to parse this.
8707 * genio.h: #include "libguile/print.h", because you need that to
8708 parse this; don't bother #including "ports.h", since print.h gets
8711 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
8713 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
8714 this; it's now a reference to an element of *scm_root.
8716 * debug.h: Don't #include "options.h"; the compiler won't be able
8717 to find that once the headers are installed; instead, #include
8718 "libguile/options.h".
8719 * gc.h: Same, with marksweep.h.
8720 * mbstrings.h: Same, with symbols.h.
8721 * scmhob.h: Same, with _scm.h.
8722 * smob.h: Same, with params.h.
8724 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
8725 C files; there's no need for this, and it forces recompilations
8728 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
8730 * error.c (scm_error): declare scm_error_callback.
8732 * error.h: prototype for scm_error_callback.
8734 * __scm.h: define lgh_error.
8735 (SCM_SYSERROR): redefine using lgh_error.
8737 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
8739 * error.c (scm_error): new procedure.
8741 * error.h: prototype for scm_error.
8743 * Makefile.in (install): install scmconfig.h from the current
8744 directory, not $(srcdir).
8746 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8748 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8749 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8750 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

8756 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8757 vports.h, weaks.h: #include "libguile/__scm.h", not
8758 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
8759 dependencies are within libguile properly.
8761 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8763 * Makefile.in (.c.x): Simplify; there's no need to run this rule
8764 when scmconfig.h doesn't exist.
8766 * load.c (scm_sys_try_load): Correct spelling.
8768 * feature.c (scm_loc_features): Make this static.
8770 * Makefile.in (libpath.h): Omit trailing slash from path. We
8771 shouldn't require it of users, so why put it here?
8773 Move code to initialize and search %load-path from ice-9 to C
8774 code, so we can use the load-path to find the ice-9 boot code;
8775 this makes it easier to run Guile without installing it. See
8776 corresponding changes in guile/Makefile.in.
8777 * feature.c: Move stuff concerned with the load path to load.c.
8778 (scm_compiled_library_path): Deleted.
8779 Don't #include libpath.h here.
8780 * feature.h: Don't mention scm_compiled_library_path.
8781 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
8782 <sys/stat.h>, and <unistd.h> (if present).
8783 (R_OK): #define if the system hasn't deigned to.
8784 (scm_loc_load_path): New variable.
8785 (scm_init_load_path, scm_sys_search_load_path,
8786 scm_sys_try_load_path): New functions.
8787 (scm_init_load): Initialize scm_loc_load_path to point to the
8788 value cell of the Scheme %load-path variable.
8789 * load.h: Add declarations for scm_sys_search_load_path,
8790 scm_sys_try_load_path.
8791 * init.c: Call scm_init_load_path.
8792 * Makefile.in (feature.o, load.o): Dependencies updated.
8794 * load.c, load.h: Rewrite using PROTO macro.
8796 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8798 * gc.c (scm_cellp): New function: C predicate to determine if an
8799 SCM value can be regarded as a pointer to a cell on the heap.
8801 * gc.h: Added declaration of scm_cellp.
8803 * gdb_interface.h: New file: The GDB interface header from the GDB
8806 * gdbint.c: New file: GDB interface.
8808 * gdbint.h: New file: GDB interface.
8810 * libguile.h: Added #include <libguile/gdbint.h>.
8812 * init.c (scm_boot_guile): Added scm_init_gdbint.
8814 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
8815 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
8816 found if object files and source are kept separate).
8818 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
8820 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
8822 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
8824 * configure.in: Don't substitute the values of TCL_SRC_DIR and
8825 TK_SRC_DIR; they're not relevant any more.
8827 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
8828 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
8830 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
8832 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
8833 search path, so we can find the <libguile/MUMBLE.h> headers.
8835 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
8837 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
8838 implicit in the .c.o rule.
8839 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
8842 Put the library path in a header file, instead of passing it on
8843 the command line in every compilation.
8844 * Makefile.in (libpath.h): New target.
8845 (feature.o): Depend on libpath.h.
8846 (clean): Delete libpath.h.
8847 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
8848 * feature.c: ... #include "libpath.h" here.
8849 * .cvsignore: Ignore libpath.h.
8851 Don't install the unwashed masses of Guile header files in the
8852 main #include path; put most of them in a subdirectory called
8853 'libguile'. This avoids naming conflicts between Guile header
8854 files and system header files (of which there were a few).
8855 * Makefile.in (pkgincludedir): Deleted.
8856 (innerincludedir): New variable; this and $(includedir) are enough.
8857 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
8858 (installed_h_files): Divide this up. Now this variable lists
8859 those header files which should go into $(includedir) (i.e. appear
8860 directly in the #include path), and ...
8861 (inner_h_files): ... this new variable says which files appear in
8862 a subdirectory, and are referred to as <libguile/mumble.h>.
8863 (h_files): List them both.
8864 (install): Create innerincludedir, not pkgincludedir. Put
8865 the installed_h_files and inner_h_files in their proper places.
8866 (uninstall): Corresponding changes.
8867 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8868 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8869 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
8870 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
8871 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
8872 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8873 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8874 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8875 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8876 vports.h, weaks.h: Find __scm.h in its new location.
8877 * __scm.h: Find scmconfig.h and tags.h in their new locations
8878 (they're both "inner" files).
8880 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
8882 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
8884 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
8886 * posix.c: Doc fixes.
8888 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
8890 * socket.c: Don't include a prototype for inet_aton; just use a
8891 K&R style declaration, to avoid warnings but minimize the chance
8892 of conflicts with the system.
8894 On NextStep, <utime.h> doesn't define struct utime, unless we
8895 #define _POSIX_SOURCE before #including it.
8896 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
8897 * acconfig.h: New comment text for above CPP symbol.
8898 * configure.in: Call it.
8899 * posix.c: #define _POSIX_SOURCE if it seems necessary.
8901 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
8903 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
8904 testing for __EMX__.
8906 * posix.c: #include <libc.h>, if it exists.
8908 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
8909 don't even know if the latter exists.
8911 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
8912 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
8913 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
8915 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
8917 (scm_init_posix): Use them when initializing the Scheme constants
8920 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
8922 * Makefile.in (libdir, includedir, bindir): Use the
8923 autoconf-supplied values, instead of deriving them ourselves.
8924 (pkgincludedir, datadir, pkgdatadir): New variables.
8925 (install, uninstall): Put the header files in a special
8926 subdirectory, not in the main search path.
8928 * Makefile.in (ALL_CFLAGS): Provide the proper value for
8929 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
8931 * Makefile.in (IMPLPATH): Deleted; never used.
8933 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
8934 on the Tcl/Tk source any more.
8935 (INCLUDE_CFLAGS): Remove references to the above.
8937 * Makefile.in (version.o): Corrected dependencies.
8939 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8941 * libguile.h: #include "version.h"
8943 * init.c (scm_boot_guile): Call scm_init_version.
8944 * gscm.c (gscm_run_scm): Call scm_init_version.
8946 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8947 GUILE_VERSION): AC_DEFINE these.
8948 (acconfig.h): #undef the above symbols.
8950 * Makefile.in (libobjs): Add version.o.
8951 (installed_h_files): Add version.h.
8952 (c_files): Add version.c.
8953 (gen_c_files): Add version.x.
8954 (version.o): New rule.
8955 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
8956 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
8957 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
8958 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
8959 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
8960 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
8961 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
8962 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
8963 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
8964 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
8965 weaks.o): Add version.h to dependency lists.
8966 (markers.o): Remove duplicate rule.
8968 * version.h: New file.
8970 * version.c: New file.
8972 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8974 * symbols.c (scm_strhash): scm_downcase is now a function, not an
8975 array; use it appropriately. Since GCC is quite happy to
8976 subscript functions, it never warned us about this; we should use
8977 -Wpointer-arith in the future. I guess we never tested
8980 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
8982 * socket.c: Doc and copyright fixes.
8984 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8986 * debug.c: Fixed and improved gdb support.
8988 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8990 * socket.c: Added declaration of inet_aton to avoid compiler
8991 warning. (Hope this solution is correct.)
8993 * stime.c: Added declaration of ftime. (This is missing in
8996 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
8998 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
9000 * Makefile.in (c_files): add strerror.c.
9002 * strerror.c: new file from Emacs' sysdep.c.
9003 maybe configure should also check for sys_errlist.
9005 * configure.in (AC_REPLACE_FUNCS): add strerror.
9007 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
9009 * debug.c (scm_init_debug): Added initialization for
9010 scm_evaluator_traps.
9012 * debug.h, debug.c: Various name changes.
9013 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
9014 "debug-options-interface". See commentary in options.c.
9016 * options.h, options.c: Options now have documentation strings.
9017 Also added a long explanatory commentary.
9019 * eval.c, print.h, print.c, read.h, read.c: Modifications to
9022 * gscm.c, init.c, root.c, throw.c: Bug fixes:
9023 last_debug_info_frame is now updated in all cases.
9025 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
9028 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
9030 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
9031 Added option STACK_CHECKING.
9033 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
9035 * Makefile.in: Added {debug,options,srcprop}.{h,c}
9037 * __scm.h: Removed symbols for debugging support.
9039 * acconfig.h: Added symbols for debugging support.
9041 * configure.in: Added user option for debugging support.
9042 --enable-debug will include the debugging code into libguile.a.
9044 * continuations.c (scm_make_cont): Enlarged the #if 0 around
9045 scm_relocate_chunk_to_heap.
9047 * debug.c: New file: low-level debugging support. It also
9048 includes support for debugging with gdb. (The extensions to gdb
9049 are written by Per Bothner at Cygnus.)
9051 * debug.h: New file: low-level debugging support.
9053 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
9054 argument pairs. Extensive modifications to the debugging
9055 evaluator. Added "SECTION:" commentaries to clarify what happens
9056 when, during double compilation. Renamed EVALIMP --> EVALIM.
9057 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
9058 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
9059 the beginning of the file. New procedure: scm_unmemocopy.
9060 Added some global state variables needed by the debugging
9061 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
9062 check_entry, check_apply, check_exit, debug_options and
9063 evaluator_traps. New acro: undefine.
9065 * eval.h: Renamed EVAL --> XEVAL.
9067 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
9068 --> scm_make_weak_key_hash_table.
9070 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
9071 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
9073 * libguile.h: Conditionally include debug.h
9075 * objprop.c (scm_object_properties, scm_set_object_properties_x):
9076 scm_object_properties shouldn't return handle. `handle' now gets
9077 initialized in scm_set_object_properties_x. scm_object_properties
9078 doesn't any longer create an entry in scm_object_whash.
9080 * options.c: New file: handling of run time options.
9082 * options.h: New file: handling of run time options.
9084 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
9086 * print.c: New procedure: scm_print_options
9088 * print.h: Defines for print options.
9090 * read.c: New procedure: scm_read_options
9092 * read.h: Defines for reader options.
9094 * root.h: Added scm_source_whash among scm_sys_protects.
9096 * srcprop.c: New file: source properties.
9098 * srcprop.h: New file: source properties.
9100 * throw.c (jbsmob): Jump buffers are now correctly allocated.
9101 (Bug found by A. Green.)
9103 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
9105 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
9107 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
9109 * libguile.h: #include "objprop.h"; I guess this was forgotten.
9111 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
9112 and should be called by the final client.
9114 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
9116 * gc.h: Use the PROTO macro when declaring functions.
9117 * gc.c: Use the PROTO macro when declaring static functions.
9118 Remove the CPP hair around function definitions.
9120 * gc.c (scm_init_storage): Initialize scm_asyncs.
9122 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
9123 preprocessor symbol; "__scm.h" is where it might get #defined.
9124 * __scm.h: Similar: #include <scmconfig.h> before testing
9127 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
9129 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
9131 * init.c (scm_boot_guile): Add init_func argument; call
9132 (*init_func) instead of calling scm_appinit; it's ucky to
9133 hard-code names for the user's procedures.
9134 * init.h (scm_boot_guile): Adjust declaration.
9136 * __scm.h (PROTO): New macro, for declaring functions with
9139 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
9140 eliminate all the __STDC__ conditionals.
9141 (scm_boot_guile): Add declaration.
9142 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
9143 Remove __STDC__ conditionals around function definitions; the
9144 declarations in init.h will provide the same information, more
9147 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
9148 complain about it in the error message; the error message is
9149 adequate without that note, and there's nothing the user can do
9152 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
9154 * Makefile.in (ancillary): Drop def.sed.
9156 * posix.c (scm_init_posix): Use numeric values, rather than
9157 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
9158 F_OK. The symbols aren't available on some systems, and I'm
9159 pretty sure their values are fixed by common widespread practice.
9160 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
9162 More functions unavailable on some systems.
9163 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
9164 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
9166 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
9167 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
9168 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
9169 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
9170 stub that signals an error as the #else.
9172 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
9174 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
9176 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
9178 * unif.c: include ramap.h.
9180 * read.c (endif): case_insensative_p renamed case_insensitive_p.
9182 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
9184 * ports.c: include sys/ioctl.h.
9186 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
9188 * configure.in: check for sys/ioctl.h.
9190 * ports.c: include <malloc.h> not "malloc.h".
9192 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
9194 * fports.c: remove ttyname and tmpnam declarations.
9196 * posix.c: fewer ttyname declarations.
9198 * fports.c: include <string.h> not "string.h".
9200 * init.c, ioext.c: include string.h and unistd.h.
9202 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
9204 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
9205 genio.c, simpos.c, vports.c: include string.h.
9207 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
9209 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
9211 (scm_addr_buffer_size): change type from scm_sizet to int.
9212 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
9213 from scm_sizet to int.
9215 * error.c: include unistd.h.
9217 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
9220 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
9222 * __scm.hd, def.sed: deleted.
9224 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
9226 Changes for NeXT, suggested by Robert Brown.
9227 * configure.in: Call AC_TYPE_MODE_T.
9228 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
9229 NeXT. Put header file list in alphabetical order.
9230 * configure, scmconfig.h.in: Regenerated.
9231 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
9233 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
9236 * acconfig.h: New file, providing documentation for the CPP
9237 symbols defined in configure.in
9238 * acconfig-1.5.h: Removed; superceded by the above.
9240 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
9242 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
9244 * fports.c (scm_open_file): don't return #f, throw error.
9246 * ioext.c (fileno): renamed from %fileno.
9247 (soft-fileno): deleted.
9249 * ports.c (scm_port_revealed): don't need to check for -1 from
9251 (scm_set_port_revealed_x): return unspecified, not #f.
9253 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
9255 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
9257 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
9259 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
9261 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
9263 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
9264 This is necessary on Ultrix, and doesn't hurt portability.
9266 * Makefile.in (dist-dir): New target, implementing a new dist system.
9267 (installed_h_files): Put in alphabetical order.
9268 Remove duplicate entries for markers.h and unif.h.
9269 (c_files): Remove duplicate entries for markers.c.
9270 (ancillary): Renamed from anillery; all uses changed. Remove
9271 PLUGIN; it's a directory, and needs special treatment in dist-dir.
9272 Remove all the ../doc/* files; doc/Makefile.in handles that.
9274 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
9276 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
9277 every if must have an else, or else the whole command has a
9278 non-zero exit code whenever the if's condition is false.
9280 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
9282 * posix.c: include string.h.
9284 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
9286 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
9289 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:

9537 initialization to fix a race condition.
9539 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

9566 The weird symbol syntax is also a bit bogus (emacs doesn't quite
