1 1999-12-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3 * eval.c (SCM_CEVAL): Removed check for unbound slot in
4 SCM_IM_SLOT_REF. (This is now handled in a smarter way in GOOPS.)
6 1999-12-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
8 * tags.h (SCM_SLOPPY_NCONSP, SCM_SLOPPY_CONSP): New macros.
9 (SCM_ECONSP): Version which doesn't mix && and || without
11 (SCM_NECONSP): Bugfree version.
13 Fri Dec 17 12:09:11 1999 Greg J. Badros <gjb@cs.washington.edu>
15 * tags.h (SCM_ECONSP, SCM_NECONSP): Fix these macros to have the
16 SCM_NIMP test integrated into an || clause that I'd missed before
17 and was causing a segfault in the regression tests.
19 * symbols.h (SCM_ROUCHARS): Make cast be to (unsigned char *), not
20 (char *); fixes a problem reported by the regression test
23 * ports.c: Fixed a couple of arg/number mismatches in
26 Now passes the (not-comprehensive) guile-modules test-suite again!
28 Thu Dec 16 12:41:22 1999 Greg J. Badros <gjb@cs.washington.edu>
30 * coop-threads.c: Remove K&R function headers.
32 * scm_validate.h: Added SCM_VALIDATE_THREAD.
34 * *.c: Remove SCM_NIMP(X) when it is an extraneous pre-test given
35 that SCM_FOOP macros all now include SCM_NIMP in their expansion.
36 This simplifies lots of code, making it far more readable.
38 Wed Dec 15 19:45:14 1999 Greg J. Badros <gjb@cs.washington.edu>
40 * *.h: Use SCM_NIMP(X) && in all the FOOP macros.
42 * *.[ch]: Use do { ... } while (0) idiom in macros that expanded
45 Tue Dec 14 10:53:14 1999 Greg J. Badros <gjb@cs.washington.edu>
47 * snarf.h: Put SCM_PROC and SCM_PROC1 back in for
48 backward-compatibility of packages that use Guile. Internally
49 Guile should not use them, though. (Maybe enforce this with a new
50 -DBUILDING_GUILE compile-time flag?).
52 Tue Dec 14 09:41:01 1999 Greg J. Badros <gjb@cs.washington.edu>
54 * backtrace.c (scm_set_print_params_x): Renamed from
57 * guile-doc-snarf.in: Use guile-snarf.awk, not
58 guile-doc-snarf.awk. Pass the basename of $filename
60 * load.h: Added prototypes for scm_sys_library_dir,
63 * load.c (scm_sys_library_dir, scm_sys_site_dir): Added these
64 functions, and took out the old scm_library_dir, scm_site_dir,
65 scm_pkgdata_dir. Now the primitives are %package-data-dir
66 (already existed), %library-dir, and %site-dir.
68 * debug.c: Use SCM_MISC_ERROR when possible instead of using
69 s_scm_* in a scm_misc_error() call.
71 * Makefile.am: Use guile-snarf.awk, not guile-doc-snarf.awk. Make
72 using guile-doc-snarf send stdout to $@ to create the .x file like
75 * guile-snarf.awk.in: Added.
77 * guile-doc-snarf.awk.in: Removed (sorry to back out a recent
78 commit; if we're going to switch to guile-snarf I figure it makes
79 sense to get this right now-- I'd already had the change in my
80 working copy when the below commit happened).
82 1999-12-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
84 * guile-doc-snarf.awk: Removed.
86 * guile-doc-snarf.awk.in: Added.
88 * ports.c (s_scm_pt_member): Fixed validation.
90 * guile-doc-snarf.in (filename): Use basename in order to strip
93 * debug.c (scm_make_iloc, s_scm_proc_to_mem): Added missing
95 (scm_memcons, scm_memcons, mem_to_proc): Renamed function name
98 * backtrace.c (set_print_params_x): Fixed GUILE_PROC macro.
100 * tags.h (SCM_UNBOUND): New iflag which is needed for some time to
101 mark the unboundness of a GOOPS slot. (Added now in order to
102 correct a oversight. Should probably be removed again and
103 replaced with SCM_UNDEFINED when the corresponding code in GOOPS
106 * print.c (scm_isymnames): Added printed representation for
109 * eval.c (SCM_CEVAL): Bugfix: Added check for unbound slot in
112 Mon Dec 13 17:23:22 1999 Greg J. Badros <gjb@cs.washington.edu>
114 * strings.c: Fixed mistaken default value in
115 scm_make_shared_substring; thanks Eric Moore!
117 Mon Dec 13 16:29:13 1999 Greg J. Badros <gjb@cs.washington.edu>
119 * guile-doc-snarf.awk: Use sub instead of gsub in ^ anchored
120 replacement for docstrings. Fixes problem Ryan Yeske observed
121 with using mawk on his system. Thanks Ryan!
123 Mon Dec 13 13:30:06 1999 Greg J. Badros <gjb@cs.washington.edu>
125 * guile-doc-snarf.in: Do not echo to stdout since the output now
126 gets stuck directly in the files instead of redirected from
129 * guile-doc-snarf.awk: Escape a literal ) -- thanks Ryan
130 Yeske. Use print instead of printf to prime the .x file since
131 AIX's cpp has problems with #include-ing empty files (according to
132 the old guile-snarf.in file).
134 Sun Dec 12 19:39:00 1999 Greg J. Badros <gjb@cs.washington.edu>
136 * Makefile.am: Fix ETAGS_ARGS to recognize GUILE_PROC,
137 GUILE_PROC1. Build guile-procedures.txt, and add that file to
140 * load.c: Added `pkgdata-dir', `site-dir', `library-dir'
143 * guile-doc-snarf.awk: Drop trailing space when no arguments:
144 e.g., "(foo )" is now "(foo)".
146 * *.c, alist.c: moved all the documentation for primitives from
147 guile-doc/ref/{appendices,posix,scheme}.texi into the source code.
148 This leaves about half of the primitives undocumented. Also, all
149 the markup is currently still texinfo. I don't have a problem
150 with texinfo per se, but the markup is not very descriptive or
153 Sun Dec 12 16:50:26 1999 Greg J. Badros <gjb@cs.washington.edu>
155 * scm_validate.h: Drop the SCM_DOCSTRING_SNARF for turning off
156 SCM_VALIDATE macros; the SCM_VALIDATE macros should be checked for
157 argument mismatches (along with the FUNC_NAME macro checking) by a
158 static tool that runs directly over the .c files.
160 * snarf.h: Handle SCM_REGISTER_PROC better when snarfing. The
161 docstring is still missing from the .doc file; it just gives the
162 name of the C function that gets called instead.
164 * guile-doc-snarf.awk: Be sure to touch the output files to help
165 make out. Also handle SCM_REGISTER_PROC better, and change the
166 output format slightly.
168 Sun Dec 12 15:33:40 1999 Greg J. Badros <gjb@cs.washington.edu>
170 * snarf.h: Drop SCM_PROC, SCM_PROC1. Added extra output for
171 guile-doc-snarf script.
173 * guile-doc-snarf.in, guile-doc-snarf.awk: New, simple doc
174 extraction system. Builds foo.x, foo.doc from foo.{c,cc}.
175 There are dependencies between these files and snarf.h. This
176 replaces guile-snarf.
178 * guile-snarf.in: Drop everything after $$$ for the new snarf.h
179 macros. This is obsoleted by guile-doc-snarf, but kept here for
180 now for good measure.
182 * Makefile.am: Added guile-doc-snarf, guile-doc-snarf.awk to
183 bin_SCRIPTS. Added .doc to SUFFIXES, and give rule for creating
184 .doc files to use guile-doc-snarf. Update the rule for creating
185 .x files to use guile-doc-snarf.
187 Sun Dec 12 12:31:38 1999 Greg J. Badros <gjb@cs.washington.edu>
189 * *.c: Finish replacing K&R style prototypes with ANSI C
192 * eval.c: Make scm_m_mody's 3rd argument be a const char *, not a
193 char *. ANSI prototypes caught this.
195 * strorder.c: Use GUILE_PROC1 for the couple SCM_PROC1 expansions
198 * scm_validate.h: Use SCM_BOOLP for validating bools. Do not
199 expand macros if SCM_DOCSTRING_SNARF.
201 Sun Dec 12 11:23:22 1999 Greg J. Badros <gjb@cs.washington.edu>
203 * *.c, srcprop.h: Use SCM_BOOL(f) instead of (f? SCM_BOOL_T:
204 SCM_BOOL_F) and use SCM_NEGATE_BOOL(f) instead of (f? SCM_BOOL_F:
207 Sun Dec 12 11:08:51 1999 Greg J. Badros <gjb@cs.washington.edu>
209 * boolean.h: Added SCM_BOOL, SCM_NEGATE_BOOL, SCM_BOOLP to here,
212 * scm_validate.h: Moved above out into boolean.h, fix typo in
213 SCM_VALIDATE_NIM macro.
215 Sun Dec 12 10:29:12 1999 Greg J. Badros <gjb@cs.washington.edu>
217 * *.c, scm_validate.h: Use SCM_VALIDATE_NIM, not SCM_VALIDATE_NIMP
218 (none of the other validate macros have the trailing P).
220 Sun Dec 12 10:07:29 1999 Greg J. Badros <gjb@cs.washington.edu>
222 * scm_validate.h: Added the FSF copyright to the top.
224 * strings.c: Use SCM_ASSERT_RANGE in a couple of places instead of
225 SCM_ASSERT w/ SCM_OUT_OF_RANGE.
227 Sat Dec 11 18:34:12 1999 Greg J. Badros <gjb@cs.washington.edu>
229 * Makefile.am: Added scm_validate.h to modinclude_HEADERS.
231 * *.c: Pervasive software-engineering-motivated rewrite of
232 function headers and argument checking. Switched SCM_PROC,
233 SCM_PROC1 macros to be GUILE_PROC, GUILE_PROC1 (may change names
234 later, but was useful to keep old versions around while migrate)
235 that has docstrings and argument lists embedded in the GUILE_PROC
236 macro invocations that expand into a function header. Use lots of
237 new SCM_VALIDATE_* macros to simplify error checking and reduce
238 tons of redundancy. This is very similar to what I did for Scwm.
240 Note that none of the extraction of the docstrings, nor software
241 engineering checks of Scwm is yet added to Guile. I'll work on
242 that tomorrow, I expect.
244 * chars.c: Added docstrings for the primitives defined in here.
246 * snarf.h: Added GUILE_PROC, GUILE_PROC1. Added
247 SCM_REGISTER_PROC to be like old SCM_PROC, though old SCM_PROC
248 still remains for now. Changed naming convention for the s_foo
249 string name of the primitive to be s_scm_foo for ease of use with
252 * scm_validate.h: Lots of new SCM_VALIDATE macros to simplify
253 argument checking through guile. Maybe some of these should be
254 folded into the header file for the types they check, but for now
255 it was easiest to just stick them all in one place.
257 1999-12-10 Greg Harvey <Greg.Harvey@thezone.net> (applied --12/10/99 gjb)
259 * smob.c (scm_smob_prehistory): initialize allocated smob
261 * tags.h: new tag: scm_tc16_allocated
263 * gc.c (scm_gc_for_newcell): set the car of the new cell
264 to scm_tc16_allocated
265 * pairs.h (SCM_NEWCELL): set the car to scm_tc16_allocated
266 (scm_gc_mark): mark allocated cells.
268 1999-12-09 Greg J. Badros <gjb@cs.washington.edu>
270 * strports.h, strports.c (scm_eval_0str): Fix constness. Some
271 thanks to Dirk Hermann.
273 * gh_eval.c (gh_eval_str, gh_eval_file, gh_eval_str_with_catch,
274 gh_eval_str_with_standard_handler,
275 gh_eval_str_with_stack_saving_handler): Fix constness. Some
276 thanks to Dirk Hermann.
278 * gh_data.c (gh_str02scm): Fix constness.
280 * gh.h: Fix constness of prototypes for the above.
282 * vectors.c: Include "unif.h" to avoid a warning about missing
283 prototype for scm_uniform_element_size().
285 1999-12-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
287 * vectors.c (scm_vector_length, scm_vector_ref, scm_vector_set_x):
288 Turned into primitive generics.
290 1999-12-04 Gary Houston <ghouston@freewire.co.uk>
292 * ports.c (scm_port_closed_p): new procedure, implements
293 "port-closed?" suggested by Bernard Urban.
294 ports.h: added prototype, removed the SCM_P macros.
296 1999-11-30 Gary Houston <ghouston@freewire.co.uk>
298 * unif.h: added some comments, removed the SCM_P macros.
300 1999-11-29 Gary Houston <ghouston@freewire.co.uk>
302 * vports.c (sf_write): use scm_makfromstr, not scm_makfrom0str
303 (thanks to Daniel Skarda).
305 1999-11-22 Jim Blandy <jimb@savonarola.red-bean.com>
307 * gscm.c, gscm.h: Deleted. They were unused.
309 1999-11-20 Gary Houston <ghouston@freewire.co.uk>
311 * unif.c (scm_list_to_uniform_array): call
312 scm_dimensions_to_uniform_array with a third argument of
313 SCM_UNDEFINED instead of SCM_EOL.
315 1999-11-19 Gary Houston <ghouston@freewire.co.uk>
317 * the following changes allow guile to be built with the array
318 "module" omitted. some of this stuff is just tc7 type support,
319 which wouldn't be needed if uniform array types were converted
322 * tag.c (scm_utag_bvect ... scm_utag_cvect): don't define unless
324 (scm_tag): don't check array types unless HAVE_ARRAYS.
326 * sort.c (scm_restricted_vector_sort_x, scm_sorted_p):
327 remove the unused array types.
328 * (scm_stable_sort, scm_sort): don't support vectors if not
329 HAVE_ARRAYS. a bit excessive.
331 * random.c (vector_scale, vector_sum_squares,
332 scm_random_solid_sphere_x, scm_random_hollow_sphere_x,
333 scm_random_normal_vector_x): don't define unless HAVE_ARRAYS.
335 * gh_data.c (makvect, gh_chars2byvect, gh_shorts2svect,
336 gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect, gh_doubles2dvect,
337 gh_uniform_vector_length, gh_uniform_vector_ref):
338 don't define unless HAVE_ARRAYS.
339 (gh_scm2chars, gh_scm2shorts, gh_scm2longs, gh_scm2floats,
341 don't check vector types if not HAVE_ARRAYS.
343 * eq.c (scm_equal_p), eval.c (SCM_CEVAL), print.c (scm_iprin1),
344 gc.c (scm_gc_mark, scm_gc_sweep), objects.c (scm_class_of):
345 don't support the array types unless HAVE_ARRAYS is defined.
347 * tags.h: make nine tc7 types conditional on HAVE_ARRAYS.
349 * read.c (scm_lreadr): don't check for #* unless HAVE_ARRAYS is
350 defined (this should use read-hash-extend).
352 * ramap.c, unif.c: don't check whether ARRAYS is defined.
354 * vectors.c (scm_vector_set_length_x): moved here from unif.c. call
355 scm_uniform_element_size if HAVE_ARRAYS.
356 vectors.h: prototype too.
358 * unif.c (scm_uniform_element_size): new procedure.
360 * init.c (scm_boot_guile_1): don't call scm_init_ramap or
361 scm_init_unif unless HAVE_ARRAYS is defined.
363 * __scm.h: don't define ARRAYS.
365 * Makefile.am (EXTRA_libguile_la_SOURCES): unif.c and ramap.c
366 moved here from libguile_la_SOURCES.
368 1999-11-18 Gary Houston <ghouston@freewire.co.uk>
370 * socket.c (scm_htons, scm_ntohs, scm_htonl, scm_ntohl): new
371 functions for network data conversion.
373 * numbers.c (scm_num2long, scm_num2longlong):
374 throw out-of-range instead of wrong-type-arg if appropriate.
375 (scm_iint2str): handle -2^31 correctly.
376 (scm_num2long): handle -2^31 bignum correctly.
377 (scm_num2long_long): rewrite the bigdig case: basically copied
379 numbers.h: (SCM_BITSPERLONGLONG): deleted.
381 * unif.c (rapr1): use sprintf instead of intprint for unsigned
382 longs: intprint can't cope with large values.
384 * numbers.c (scm_num2ulong): check more consistently that the
385 input is not negative. if it is, throw out-of-range instead of
388 * ramap.c (scm_array_fill_int): don't limit fill to INUM for
389 uvect, ivect or llvect.
390 Check that fill doesn't overflow short uniform array.
392 * __scm.h: add another long to the definition of long_long and
395 * unif.c (scm_raprin1): use 'l' instead of "long_long" in the
396 print representation of llvect. read can't handle more than
398 (scm_dimensions_to_uniform_array): make "fill" an optional argument
399 instead of a rest argument.
401 * tags.h (scm_tc7_llvect): wasn't defined anywhere, so use the free
404 * __scm.h: don't mention LONGLONGS.
406 * unif.c, numbers.c, eq.c, gc.c, print.c, eval.c, ramap.c:
407 replace LONGLONGS with HAVE_LONG_LONGS as set by configure.
409 1999-11-17 Gary Houston <ghouston@freewire.co.uk>
411 * net_db.c (scm_inet_aton): throw errors using the misc-error key
412 instead of system-error. inet_aton doesn't set errno.
413 system-error isn't right in gethost either, since it's throwing
414 the value of h_errno instead of errno. so:
415 (scm_host_not_found_key, scm_try_again_key,
416 scm_no_recovery_key, scm_no_data_key): new error keys.
417 (scm_resolv_error): new procedure, use the new keys.
418 (scm_gethost): call scm_resolv_error not scm_syserror_msg.
420 1999-11-16 Gary Houston <ghouston@freewire.co.uk>
422 * error.c: (various): use scm_cons instead of scm_listify
423 to build short lists.
425 1999-11-03 Gary Houston <ghouston@freewire.co.uk>
427 * socket.c (scm_fill_sockaddr): zero the address structure before
428 use, in case it has a sin_len field and the OS doesn't like random
429 values (thanks to Bertrand Petit).
431 1999-10-26 Mark Galassi <rosalia@lanl.gov>
433 * gh.h, gh_data.c (gh_symbol2scm): changed gh_symbol2scm() to take
434 a const char * argument, upon suggestion from Lynn Winebarger.
436 1999-10-26 Gary Houston <ghouston@freewire.co.uk>
438 * strports.c (st_end_input): avoid dubious pointer arithmetic.
440 1999-10-24 Gary Houston <ghouston@freewire.co.uk>
442 * Move the responsibility for resetting port buffers from the
443 caller of the ptob seek procedure to the implementation. This
444 gives more control in general to the ptob seek: in particular the
445 change of 1999-10-20 can be made to work without breaking seek on
446 string ports. There's a comment in NEWS about upgrading port
449 * ports.c (scm_seek): don't reset the port buffers here.
451 * fports.c (fport_seek): reset the buffers, except for the
454 * strports.c (st_end_input): (bug fix): decrement pt->read_pos by
455 offset. check that it's not less than read_buf.
456 (st_seek): reset the buffers first, unless it's the 0 SEEK_CUR
457 case and currently reading.
459 1999-10-20 Gary Houston <ghouston@freewire.co.uk>
461 * ports.c (scm_seek): Add a special case for SEEK_CUR, offset 0,
462 so that unread chars are not needlessly discarded. (thanks to
465 1999-10-18 Gary Houston <ghouston@freewire.co.uk>
467 * fports.c (scm_fdes_to_port): always set rw_random if the fdes is
468 random access. rw_active needs to be maintained even for single
469 directional ports, otherwise scm_seek and probably other things are
470 broken. (thanks to Roland Orre).
472 * strports.c (scm_mkstrport): set rw_random to 1 unconditionally.
474 * ports.c (scm_add_to_port_table): initialise rw_random to 0.
476 * ports.h (scm_port): change the comments on rw_random and rw_active.
478 1999-10-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
480 * ioext.c: Added #include "feature.h".
482 These changes turns `delay' into a memoizing macro. This is
483 because it may be expanded before evaluation if it occurs at the
484 beginning of a body. (Thanks to Lauri Alanko.)
486 * eval.c, eval.h (scm_sym_delay): New global symbol.
488 * tags.h (SCM_IM_DELAY): New immediate symbol.
490 * print.c (scm_isymnames): Printed representation.
492 * eval.c (unmemocopy, SCM_CEVAL): Handle SCM_IM_DELAY.
493 (scm_m_delay): Turned into a memoizing macro.
495 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version.
497 1999-10-11 Jim Blandy <jimb@savonarola.red-bean.com>
499 * gh_data.c (gh_ints2scm, gh_doubles2scm): Make sure elements are
500 protected from GC while building the vector. (Thanks to Bernard
501 Urban and Greg Harvey.)
503 1999-10-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
505 * throw.c (handler_message): Display backtrace if backtraces
508 1999-10-05 Jim Blandy <jimb@savonarola.red-bean.com>
510 * Makefile.in, scmconfig.h.in: Deleted from CVS repository. Run
511 the autogen.sh script to create generated files like these.
513 * numbers.c (scm_string_to_number): Signal an error if radix is
514 less than two. (Thanks to Jorgen Schaefer.)
516 * print.c (scm_write, scm_display, scm_newline, scm_write_char):
517 Don't assume that the current output port is valid. Somebody
518 might close it. (Thanks to Bernard Urban.)
520 1999-10-02 Jim Blandy <jimb@zwingli.cygnus.com>
522 * scmconfig.h.in: Regenerated.
524 * Makefile.am (EXTRA_libguile_la_SOURCES): fix typo.
526 Mon Sep 27 17:15:14 1999 Greg J. Badros <gjb@cs.washington.edu>
528 * __scm.h: Fix a bunch of macros that were missing do-while(0)
531 * debug.c, eval.c: Fix buggy uses of SCM_ALLOW_INTS (missing
532 semicolon) exposed by the above change.
534 1999-09-27 Greg J. Badros <gjb@cs.washington.edu>
536 * stacks.c: Avoid compiler warning re: unitialized var.
538 * scmconfig.h.in: Added DEBUG_FREELIST
540 * pairs.h: Fix macro that was not do-while(0) sandwiched.
542 * gc.h, gc.c: Added scm_gc_set_debug_check_freelist_x,
545 1999-09-23 Gary Houston <ghouston@freewire.co.uk>
547 * ioext.c (scm_init_ioext): enable "i/o-extensions" feature here
548 instead of in scm_init_filesys.
550 * init.c (scm_boot_guile_1): don't call scm_init_posix or
551 scm_init_filesys unless HAVE_POSIX is defined.
552 don't call scm_init_netdb or scm_init_socket unless
553 HAVE_NETWORKING is defined.
555 * Makefile.am (EXTRA_libguile_la_SOURCES): filesys.c, posix.c,
556 net_db.c, socket.c: moved here from libguile_la_SOURCES.
558 1999-09-25 Jim Blandy <jimb@savonarola.red-bean.com>
560 * root.c (scm_make_root): Initialize all the fields of the new
561 root. GC could happen any time, you know. (Thanks to Greg
564 * numbers.c (scm_number_to_string): Signal an error if radix is
565 less than two. (Thanks to Jorgen Schaefer.)
567 * Makefile.am (EXTRA_libguile_la_SOURCES): Add memmove.c here,
568 so automake will actually generate rules for it.
569 * Makefile.in: Regenerated.
571 1999-09-21 Jim Blandy <jimb@savonarola.red-bean.com>
573 * backtrace.c: #include "_scm.h" before testing whether
574 HAVE_UNISTD_H is #defined.
576 1999-09-20 Jim Blandy <jimb@savonarola.red-bean.com>
578 * read.c (scm_read): Don't assume that scm_cur_inp is always open.
579 * ports.c (scm_read_char): Same.
580 * ioext.c (scm_read_line): Same.
581 (Thanks to Bernard Urban.)
583 1999-09-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
585 * vectors.c (scm_vector_move_right_x): Bugfix: Remove side effect
587 numbers.c: Removed #ifndef SCM_RECKLESS at places where type
588 checking may invoke a generic. (Thanks to Michael Livshin.)
590 * __scm.h (SCM_WTA_DISPATCH_0, SCM_GASSERT0): New macros.
592 * numbers.c (scm_max, scm_min, scm_sum, scm_difference,
593 scm_product, scm_divide): Bugfix: Don't pass SCM_UNDEFINED to the
594 generic function if the asubr is called with only one arg.
596 1999-09-20 Gary Houston <ghouston@freewire.co.uk>
598 * scmsigs.c (scm_sigaction): add SA_RESTART to flags only if
599 HAVE_RESTARTABLE_SYSCALLS.
600 (scm_init_scmsigs): use siginterrupt if it's available. not
601 everyone who has restartable syscalls has SA_RESTART it seems.
603 (scm_sigaction): use scm_num2long/scm_long2num when converting
604 SIG_DFL/SIG_IGN, in case it doesn't fit in an INUM. use
605 scm_integer_p to test the type.
607 1999-09-18 Gary Houston <ghouston@freewire.co.uk>
609 * _scm.h, scmsigs.c: replace HAVE_RESTARTS with
610 HAVE_RESTARTABLE_SYSCALLS.
612 * strports.c (scm_strport_to_string): create the string from
613 pt->read_buf instead of an expression that evaluates to the
616 * gdbint.c (gdb_print): don't just use SCM_CHARS to get a C string
617 from the port: the port's buffer may not be NUL terminated.
619 1999-09-16 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
621 * Makefile.am (.c.x): Added missing semicolon after `false'.
623 1999-09-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
625 * print.c (scm_iprin1): Turn `write' and `display' into
626 primitive generics and use their associated generic functions in
627 scm_iprin1 for GOOPS objects.
629 * backtrace.c: #include <unistd.h> if present.
631 1999-09-14 Jim Blandy <jimb@savonarola.red-bean.com>
633 * Makefile.am (.c.x): Don't create a subshell just to delete the
634 .x file and return false.
635 * Makefile.in: Regenerated.
637 1999-09-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
639 * feature.c (scm_create_hook): New function. Replaces
640 scm_make_named_hook which is now deprecated.
641 (scm_make_hook_with_name): New primitive.
642 (print_hook): Hooks now print in a fancy way.
644 1999-09-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
646 * __scm.h, backtrace.c, backtrace.h, debug.c, debug.h, dynl-dld.c,
647 dynwind.c, dynwind.h, eval.h, evalext.c, evalext.h, feature.c,
648 feature.h, hashtab.c, hashtab.h, objects.c, objects.h, print.c,
649 procs.c, procs.h, smob.c, smob.h, srcprop.c, strorder.c, struct.c,
650 struct.h: Updated copyright notices.
652 * srcprop.c (scm_source_property): Bugfix: Use SCM_NECONSP instead
653 of SCM_NCONSP. (Thanks to Greg Badros.)
655 * gsubr.c (scm_make_gsubr): Use scm_make_subr_opt for creation of
658 * eval.c, debug.h (SCM_BACKTRACE_WIDTH): New debug option: width.
660 * backtrace.c: Keep backtraces within specified width by
661 adaptively adjusting fancy printing parameters and cut output if
663 (scm_display_application): Check args.
665 1999-09-11 Jim Blandy <jimb@savonarola.red-bean.com>
667 Change the name of the objects returned by OPENDIR from
668 "directory" to "directory stream". A predicate named "directory?"
670 * filesys.c (scm_directory_stream_p): Renamed from scm_directory_p.
671 At the Scheme level, "directory?" -> "directory-stream?".
672 (scm_dir_print): Use the phrase "directory stream" in printed form.
673 * filesys.h (scm_directory_stream_p): Prototype renamed
676 * Makefile.am (CLEANFILES): Remove versiondat.h; that should only
677 be removed by `make distclean', since it's generated by configure.
678 * Makefile.in: Regenerated.
679 (Thanks to Robert Bihlmeyer.)
681 * strop.c (scm_substring_move_x): Signal an error if start1
682 doesn't come before end1. (Thanks to Karoly Lorentey).
684 * numbers.c (scm_istr2flo): Don't call SCM_INEXP without first
685 calling SCM_NIMP. (Thanks to Karoly Lorentey).
687 * version.c (scm_libguile_config_stamp): Deleted. See
688 corresponding change to ../ice-9/boot-9.scm.
689 * versiondat.h.in: Remove definition for GUILE_STAMP.
690 * version.h: Delete prototype.
691 * Makefile.in: Regenerated.
693 1999-09-11 Gary Houston <ghouston@easynet.co.uk>
695 * filesys.c (scm_directory_p): new procedure "directory?" Returns
696 a boolean indicating whether its argument is a directory
697 port as returned by opendir (thanks to Dirk Herrmann for the
700 1999-09-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
702 * backtrace.c (display_frame_expr): Don't print a newline.
703 (display_frame): Print the newline here instead.
704 (display_backtrace_body): Don't print "Backtrace:".
705 (scm_backtrace): Print "Backtrace:" here instead.
707 1999-09-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
709 * procs.c (scm_setter): Signal WTA if handed an entity or operator
712 * feature.c, feature.h: (scm_hook_p, scm_hook_empty_p): New
713 primitives. (Thanks to Greg Badros);
714 (scm_hook_to_list): New primitive; Hooks are now smobs.
716 1999-09-08 Gary Houston <ghouston@easynet.co.uk>
718 * stime.c (bdtime2c): rewrite the ASSERTs. Accept a value
719 of #f for the 10th vector element to avoid an exception
720 seen by Bernard Urban.
721 (scm_mktime): unneeded ASSERT removed.
723 1999-09-07 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
725 * eval.c (scm_map, scm_for_each): Converted to dispatch on generic
728 * __scm.h (SCM_WTA_DISPATCH_n, SCM_GASSERTn): New macros.
730 1999-09-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
732 * numbers.c: Converted comparison operations to dispatch on
733 generic if args don't match.
735 * Makefile.am (ETAGS_ARGS): Added support for GPROC and GPROC1.
737 1999-09-06 James Blandy <jimb@mule.m17n.org>
739 * guile-snarf.c: Deleted. Snarfing should respect CPP
740 conditionals, so it needs to actually run CPP. Bleah.
742 1999-09-05 James Blandy <jimb@mule.m17n.org>
744 Handle errors properly in guile-snarf. (Thanks to Han-Wen Nienhuys.)
745 * guile-snarf.in: Be sure to exit with an error if CPP does.
746 * Makefile.am (.c.x): Delete the .x file and exit with an error
747 status if guile-snarf exits with an error status.
748 * Makefile.in: Regenerated.
750 * snarf.h (SCM_GLOBAL_KEYWORD): Call scm_c_make_keyword, not
751 scm_makekey, which doesn't exist any more. Guess nobody's using
754 * guile-snarf.c: New implementation of guile-snarf, meant to be
755 more robust than the shell script. I think it's complete, but I
756 haven't tested it at all, and I haven't changed the build process
757 to actually use it. We should compare its output against that of
758 the existing shell script, for all source files.
760 * guile-snarf.c (parse_args): Abort if we haven't handled some
763 1999-09-03 James Blandy <jimb@mule.m17n.org>
765 * load.c (scm_search_path): If the filename has any extension at
766 all, ignore the entire list of extensions. Also, don't check whether
767 the file is accessible. If the file exists, accessible or not, we
768 should return it. Inaccessible files should cause an error later.
769 (Thanks to Keisuke Nishida for the suggestions.)
771 1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
773 * gc.c (cleanup, scm_init_storage): Use on_exit if present and
774 atexit not available. (sunos4.1.4 needs it.)
776 1999-09-01 James Blandy <jimb@mule.m17n.org>
778 I take it all back --- bcopy does handle overlapping source and
779 destination areas correctly. At least on every system I could
780 find. But it is better to use AC_REPLACE_FUNCS than to introduce
781 new CPP conditionals.
782 * memmove.c: New file, implementing memmove in terms of bcopy.
783 * scmconfig.h.in: Regenerated.
785 Allocators should use the `void *' type for generic pointers.
786 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
787 argument and return types.
788 * gc.h: Corresponding changes to prototypes.
791 1999-08-31 James Blandy <jimb@mule.m17n.org>
793 * numbers.c (scm_init_numbers): Claim to support the `complex'
794 feature, as expected by (ice-9 format). (Thanks to Ceri Storey.)
796 * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
797 find (ice-9 boot-9) when Guile was compiled in a separate
798 directory from the source. (Thanks to Rodney Brown.)
799 * Makefile.in: Regenerated.
801 * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply
802 table lengths by the size of a single element when growing the
803 table. (Thanks to Bill Schottstaedt.)
805 1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
807 * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
808 SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
809 since that cuts down the time for type dispatch by 50%.
811 1999-08-30 James Blandy <jimb@mule.m17n.org>
813 * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
814 not a correct substitute for memmove, because it doesn't handle
815 overlapping source and destination areas on many platforms.
816 Overlaps are the primary reason to use memmove in the first place.
817 * ports.c (scm_ungetc): Same.
818 * strop.c (scm_substring_move_x): Same.
820 1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
822 * gc.c (scm_init_storage): Skip registration of cleanup on systems
823 which lack atexit. (Is it important that cleanup is made
824 properly? Maybe we should replace all `exit' with `scm_exit' and
827 * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
828 scm_struct_free_standard, scm_struct_free_entity): Declared to
829 return scm_sizet instead of size_t.
831 * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined
832 there on sunos4.1.4.)
834 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
836 * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
837 Account for the case when second argument is unbound.
839 * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
840 (Thanks to Karoly Lorentey.)
842 * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
843 isn't present. (Thanks to Suzuki Toshiya.)
845 * ports.c: Use ANSI C prototypes in definitions. (Thanks to
848 * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
851 * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
852 Bernard Urban and Ian Grant.)
854 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
855 again. (1.3.4 will be binary incompatible with 1.3.2 because of a
856 change in the representation of entities and operators.)
858 1999-08-29 Gary Houston <ghouston@easynet.co.uk>
860 * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
861 don't allocate zero bytes (thanks to Bill Schottstaedt).
863 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
865 * procs.c (scm_setter): Converted to use generic dispatch.
867 * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
870 * load.c (scm_search_path): Don't try extensions which already are
871 present at the end of the filename.
872 (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
874 * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
876 Cleanup and simplification of generic method dispatch.
877 Also, the quadruple representation of entity and operator
878 procedures has been replaced with single.
880 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
882 * print.c (scm_isymnames): Removed #@hash-dispatch.
884 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
885 from eval.c; Support 0 arity methods.
886 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
887 (scm_apply_generic_env): Removed.
888 Replaced slots proc0-3 with procedure.
890 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
891 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
892 SCM_OPERATOR_PROCEDURE.
893 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
894 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
896 * struct.c, struct.h: Replace 4 procedure slots with one.
897 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
899 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
902 * eval.c (scm_sym_args): Removed.
903 (SCM_CEVAL): Simplified entity application.
904 Moved dispatch code to objects.c.
906 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
908 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
910 * sort.c (closureless): Use scm_eval_body.
912 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
913 with a symbol as last form was first called normally and then via
914 `map' or some other mechanism using primitive apply, an ILOC was
917 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
919 This change extends the representation of primitive procedures
920 with more data fields, e.g. a place for documentation and true
921 procedure properties.
923 * procs.c, procs.h (scm_subr_entry): New type: Stores data
924 associated with subrs.
925 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
926 SCM_SUBR_DOC): New macros.
927 (scm_subr_table): New variable.
928 (scm_mark_subr_table): New function.
930 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
932 * gc.c (scm_gc_mark): Don't mark subr names here.
933 (scm_igc): Call scm_mark_subr_table.
936 This change implements a scheme for letting a generic work as a
937 shadow for a primitive procedure. If the primitive procedure
938 can't dispatch on its arguments, control is left over to the
939 generic. Normal wrong type arg errors will be generated until the
940 user has hung the first method on the primitive.
942 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
944 * procs.c, procs.h (scm_subr_p): New function (used internally).
946 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
948 * objects.c, objects.h (scm_primitive_generic): New class.
950 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
952 * print.c (scm_iprin1): Print primitive-generics.
954 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
955 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
957 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
958 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
959 primitives). NOTE: This means that it is now *required* to use
960 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
961 obscured representation that will be removed in the future anyway,
962 so backward compatibility is no problem here).
964 * numbers.c: Converted most numeric primitives (all but bit
965 comparison operations and bit operations) to dispatch on generic
969 Better support for applying generic functions.
971 * eval.c, eval.h (scm_eval_body): New function.
973 * objects.c (scm_call_generic_0, scm_call_generic_1,
974 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
978 Optimization of the generic function dispatch mechanism.
980 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
981 called scm_memoize_method instead of doing a second lookup.
983 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
988 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
989 scm_sysintern so that the binding connected with the subr name
990 isn't cleared when we give set = 0.
993 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
995 More transparent handling of ports with print states.
997 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
998 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
999 instead of a pair of a port and a print state. We'll need to cons
1000 once extra in scm_printer_apply but the type system will be
1001 cleaner, it will mix better with GOOPS, and, it will be even more
1002 transparent to the user.
1004 * print.c (scm_get_print_state): New procedure: Given an output
1005 port, return the print state associated to it in the current print
1006 chain, if one exists;
1007 (scm_port_with_print_state): New procedure: Associate a
1008 print-state with a port.
1009 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
1010 (scm_printer_apply): Wrap port and pstate as a smob;
1011 (print_state_printer): Removed.
1013 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
1015 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
1018 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
1019 testing (otherwise the port-print-state trick won't be transparent
1020 to the user; one example where this caused problems was in the
1021 (ice-9 format) module).
1023 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1025 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
1026 SCM_UNSPECIFIED instead of the set value.
1028 1999-08-20 James Blandy <jimb@mule.m17n.org>
1030 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
1032 * ports.h (enum scm_port_rw_active): New enum, containing
1033 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
1034 zero). The debugger knows about enums, but doesn't know about
1036 (typedef scm_port): Declare rw_active member to be an enum
1038 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
1040 * ports.c (scm_add_to_port_table): Same.
1041 * strports.c (st_flush, st_end_input): Same.
1043 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
1044 scm_must_realloc, and scm_done_malloc as appropriate.
1046 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1048 * sort.c (quicksort): Added condition to protect the algorithm
1049 from crashing the interpreter if the less predicate is buggy.
1051 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
1053 * fports.c (fport_write): fix line-buffering mode again.
1054 (scm_open_file): recognise 'l' for line-buffering.
1055 (scm_setvbuf): recognise _IOLBF for line-buffering.
1057 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1059 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
1062 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
1063 evaluating closures.
1065 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
1067 * fports.c (fport_write): use memcpy instead of strncpy, in case
1068 the data contains NUL.
1070 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1072 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
1074 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
1075 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
1076 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
1077 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
1078 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
1079 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
1080 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
1081 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
1082 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
1083 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
1084 scm_sym_ as prefix for symbols.
1086 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
1088 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
1089 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
1090 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
1091 scm_sym_atcall_cc): Made global.
1093 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1095 * eval.c (scm_sym_args): Made global.
1097 * objects.c (scm_set_object_procedure_x): Disallow setting of
1098 procedures for pure generic functions.
1100 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
1102 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
1103 Scheme name from lseek to seek, but lseek was added recently so
1104 it shouldn't be a big problem.
1105 * ports.c, gdbint.c, ioext.c: changed callers.
1107 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
1109 * fports.c (fport_input_waiting): if select is used, return 1
1110 instead of whatever FD_ISSET expands to. maybe it will be useful
1111 to interpret the value from the input_waiting ptob procedure as a
1112 lower bound on the number of bytes available.
1114 * Mikael asked for a few names to be changed...
1116 * ports.c (scm_make_port_type): take the write procedure as the
1117 second argument instead of the flush procedure.
1118 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
1119 fflush -> flush, read_flush -> end_input, fclose -> close,
1120 fill_buffer -> fill_input, ftruncate -> truncate,
1121 input_waiting_p -> input_waiting.
1123 * ports.c (end_input_void_port): was read_flush_void_port.
1124 (scm_set_port_end_input): was scm_set_port_flush_input.
1125 (scm_set_port_flush): was scm_set_port_write.
1126 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
1127 (scm_end_input): was scm_read_flush.
1128 (scm_fill_input): was scm_fill_buffer.
1129 (scm_flush): was scm_fflush.
1130 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
1131 (fport_end_input): was local_read_flush.
1132 (fport_flush): was local_fflush.
1133 (fport_close): was local_fclose.
1134 (fport_truncate): was local_ftruncate.
1135 (fport_seek): was local_seek.
1136 (fport_free): was local_free.
1137 (fport_fill_input): was fport_fill_buffer.
1138 * strports.c (st_end_input): was st_read_flush.
1139 (st_truncate): was st_ftruncate.
1140 * vports.c: (sf_flush): was sfflush.
1141 (sf_close): was sfclose.
1142 (sf_fill_input): was sf_fill_buffer.
1144 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
1147 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1149 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
1150 forms now contain the expressions to be dispatched upon instead of
1151 depending on a surrounding lambda or let; Generic function
1152 dispatch has been optimized; `apply' on a generic function now
1153 works a little bit strangely. It uses a trick so that the type
1154 dispatch code in SCM_CEVAL can be reused.
1156 * objects.h, objects.c (scm_apply_generic_env): Added (used by
1158 (scm_operator_p): Added.
1159 (scm_sym_atdispatch): Added.
1160 (scm_set_object_procedure_x): Modified to handle the new style
1162 (scm_object_procedures): New debugging procedure.
1164 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1166 * eval.c, eval.h (scm_sym_args): Added.
1168 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
1170 * feature.c, feature.h (scm_c_run_hook): Added.
1172 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
1173 cdrxnoap and loopnoap instead of begin and loop.
1175 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
1177 * ports.c (scm_putc, scm_puts),
1178 * unif.c (scm_uniform_array_write): use scm_lfwrite.
1179 * ports.c (scm_putc): change type of first argument from int to char.
1181 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1183 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
1184 SCM_IM_HASH_DISPATCH.
1186 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
1187 (scm_si_redfined, scm_si_hashsets): Moved.
1189 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
1190 flag which combines type and status info so that the class
1191 redefinition protocol has zero cost during normal execution.
1193 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
1195 * ports.h (scm_ptob_descriptor): include a write procedure again.
1196 it's more efficient for unbuffered fports (e.g., sockets.)
1198 * ports.c (scm_puts): use ptob->write.
1199 * vports.c (scm_make_sfptob): set write proc in ptob.
1200 * strports.c (scm_make_stptob): set write proc in ptob.
1201 * ports.c (write_void_port): new procedure.
1202 * vports.c (sf_write): new procedure.
1203 * ports.c (scm_lfwrite): use ptob->write.
1204 * strports.c (st_write): new procedure.
1205 * fports.c (fport_write): new procedure.
1206 (scm_make_fptob): set write in ptob to fport_write.
1207 * ports.h: prototype for scm_set_port_write.
1208 * ports.c (scm_make_port_type): initialise ptob write procedure.
1209 (scm_set_port_write): new proc.
1211 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
1213 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
1214 until we've verified that it is actually a port. (Thanks to
1217 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1219 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
1220 code, particularly an unnecessary test (len != size, where len ==
1221 size). (Was this leftovers from debugging code, or have I missed
1222 something profound?)
1224 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
1225 size. (Thanks to James Dean Palmer.)
1227 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
1228 (Thanks to Lorentey Karoly.)
1230 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1232 * eval.c (scm_m_expand_body): Use scm_cons_source.
1234 * struct.c (scm_print_struct): Use vtable name.
1236 * print.c (scm_init_print): Set name of print state type.
1238 * stacks.c (scm_init_stacks): Set name of stack type.
1240 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1242 * eval.c (SCM_CEVAL): Removed old implementation of internal
1245 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
1247 * debug.c, debug.h (scm_reverse_lookup): Added.
1248 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
1249 internal procedure definitions; Don't use scm_i_inner_name.
1251 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
1252 New isym operations.
1254 * eval.h: Added prototypes for multi language support functions.
1256 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
1257 improper lists in the low-level representation, since that will
1258 cause a begin to be prepended at macro expansion.
1260 * eval.c (scm_cons_source): Version of cons which copies source
1261 properties from an existing cell.
1262 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
1264 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
1265 procedure source before calling scm_unmemocopy instead of faking
1268 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1270 Ported `internal defines' fix from SCM. Original ChangeLog entry:
1272 1998-07-09 Radey Shouman <radey@colorage.com>
1274 * eval.c (ceval_1): Modifications to allow rewriting of interal
1275 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
1276 body of which it is the CAR is macro expanded by m_expand_body,
1277 which rewrites internal DEFINE.
1279 (m_expand_body): Added.
1281 (m_macroexp1): Added argument to control error checking:
1282 m_expand_body may speculatively expand forms in the wrong
1283 environments. Made argument number checks conditional on
1286 (m_body): Added, error checks bodies and inserts the ISYM tokens.
1288 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
1291 (m_cond): (m_case): (m_quote): Modified to avoid destructively
1292 changing their argument forms. Since m_expand_body
1293 speculatively macro expands forms the process must be
1296 (m_ident_eqp): Fixed to use proper environment.
1298 (renamed_ident): Added DEFER_INTS_EGC.
1300 Added prototypes for static functions.
1306 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
1307 is false, do not produce an error for unbound variables, return a
1308 pointer to cell_undef instead.
1310 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
1314 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
1315 destructively changing their argument forms. Since m_expand_body
1316 speculatively macro expands forms the process must be reversible.
1318 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
1319 SCM_IM_LET introduced by named lets.
1321 (scm_m_letstar): Use scm_m_body instead of bodycheck.
1323 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
1324 scm_letrec. scm_letrec1 does not check for a null binding and
1325 takes an additional argument to specify the ISYM of the body. Use
1326 scm_m_body instead of bodycheck.
1328 (scm_m_let): Use scm_m_body instead of bodycheck.
1330 (scm_m_expand_body, scm_macroexp): New.
1332 (unmemocopy): Account for ISYMs introduced by scm_m_body.
1334 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
1335 check=1. Throw error for internal defined that have not been
1336 rewritten by scm_m_expand_body.
1338 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
1339 Removed prototype for SCM_APPLY.
1341 * tags.h: Added extern declaration of scm_isymnames.
1343 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1345 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
1347 * lang.c: New file: Beginning of multi-language support.
1349 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
1351 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
1352 (scm_dynamic_wind): Added argument checking for the after guard so
1353 that we don't add garbage on the dynwind chain.
1354 (scm_swap_bindings): Added.
1356 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
1357 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
1358 (scm_isymnames): New isyms for multi-language support.
1360 * eval.c (scm_nil, scm_t): New symbols.
1361 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
1362 forms for multi-language support.
1364 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1366 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
1368 Renamed functions in the random function library interface
1369 from scm_i_XXX --> scm_c_XXX.
1371 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
1373 * ports.c (scm_putc): fix line-buffering.
1375 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1377 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
1378 scm_set_ptob_XXX --> scm_set_port_XXX.
1380 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1382 * ports.c, ports.h (scm_make_port_type): New interface for
1383 creation of port types (replaces scm_newptob). Just as for the
1384 smobs, we need to separate the internal representation of smob
1385 types from the interface, so that we easily can add new fields and
1386 rearrange things without caring about backward compatibility.
1387 This change was forced by the need in GOOPS to create classes
1388 representing port types.
1389 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
1390 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
1391 scm_set_ptob_seek, scm_set_ptob_truncate,
1392 scm_set_ptob_input_waiting_p): New setters.
1393 (scm_newptob): Rewritten to use scm_make_port_type. For backward
1395 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
1396 (scm_prinport): Removed.
1397 (scm_port_print): Added.
1398 (scm_print_port_mode): Added.
1399 (void_port_ptob, print_void_port, close_void_port, noop0):
1400 Removed. Removed #include "genio.h" Added #include "objects.h",
1403 * fports.c (prinfport): Moved code from ports.c.
1404 (local_free): Added.
1405 (scm_fptob): Removed. Instead use new interface.
1406 (scm_make_fptob): Added. (Need to create basic ports in a
1407 specific order in ports.c.)
1409 * strports.c (scm_stptob, prinstpt, noop0): Removed
1410 (scm_make_stptob): Added.
1412 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
1413 (scm_make_sfport): Added.
1415 * filesys.c (scm_dir_print): Don't use the port printing code.
1416 Instead provide specific directory printer.
1418 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
1420 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
1421 scm_ptob_descriptor.
1423 * smob.c (scm_smob_print): Handle non-existing type name nicely.
1424 Removed #include "genio.h"
1426 * objects.c (scm_make_port_classes): New function ptr.
1428 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
1430 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
1432 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
1433 allow the 1st argument to be a fdes or filename as well as a
1434 port (as in the filesys.c version).
1436 * filesys.c (scm_truncate_file): removed.
1438 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1440 * readline.c, readline.h: Removed.
1442 * objects.c, objects.h (scm_port_class): Added.
1443 (scm_class_of): Look up port class in scm_port_class.
1444 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
1445 SCM_INOUT_PCLASS_INDEX): Added.
1448 * Makefile.am: Removed genio.c, genio.x.
1452 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1454 * init.c: Make sure that scm_post_boot_init_modules is called only
1455 once. (Important when using a dumped image.; Thanks to Bernard
1458 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
1460 * guardians.c (scm_guardian_zombify): Separate scanning for
1461 zombies from marking the pairs of the free list.
1463 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
1464 use the macros. (Thanks to Michael Livshin.)
1466 * eval.c (scm_m_lambda): Let bodycheck check the body of the
1467 lambda. Let your sins be purified by the blood of the lambda.
1468 (Thanks to Eric Hanchrow.)
1470 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
1471 (Thanks to Valdis Kletnieks.)
1473 Fixes for EMX from Mikael Ståldal.
1475 * filesys.c: #include <io.h>, if we have it.
1476 * scmconfig.h.in: Regenerated.
1478 * stime.c (ftime): Delete declaration for this function --- let
1479 the system supply it.
1481 Cleanups from John Bley.
1483 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
1485 * gsubr.c: Don't include "gsubr.h" twice.
1487 Cleanups for compilation on Irix 6, from David Kaelbling.
1489 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
1490 regex_t pointer. This is what the callers have, mostly.
1491 (scm_regexp_exec): Don't forget to pass the `rx' argument to
1492 scm_regexp_error_msg.
1494 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
1495 int. That way, if we get a warning on this line, it's more likely
1496 that we're really missing bits we care about.
1498 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
1501 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
1502 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
1503 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
1504 cast at all is more appropriate in every case. At the moment, we
1505 assume everywhere that SCM is an integral type anyway.
1507 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
1509 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
1510 read_pos after scm_fill_buffer.
1512 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
1515 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
1516 fports.c (fport_fill_buffer): implement the interface change.
1518 * ports.c (scm_fill_buffer): interface change: no longer increments
1519 read_pos past the character that's returned. it seems clearer to
1520 leave it to the caller to decide what to do (thanks Jim).
1522 * vports.c (sf_fill_buffer): put the read char into the buffer
1523 as well as returning it.
1525 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure
1528 1999-07-13 Gary Houston <ghouston@easynet.co.uk>
1530 * strports.c (scm_strprint_obj): simplify. start with initial
1532 (st_seek): don't allow string to be extended if seeking past
1533 the end of a read-only port.
1535 1999-07-12 Gary Houston <ghouston@easynet.co.uk>
1537 * strports.c (st_seek): change the resize checks.
1539 * ports.c (scm_ftruncate): throw error if offset works out negative.
1541 * strports.c (st_flush): increase string size in blocks of
1542 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
1543 it's greater and reset read_buf_size.
1544 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
1545 to be maintained for output ports too (it holds the written
1546 part of the string, while write_buf may have unwritten buffer
1548 (st_truncate): rewritten.
1549 (top of file): added a few notes.
1551 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
1553 Patch from Greg Badros:
1554 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
1555 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
1556 (function pointer) argument to scm_make_gsubr and scm_make_subr
1557 calls. This avoids warnings in C++ programs using guile-snarf.
1559 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
1561 * strports.c (st_grow_port): set pt->read_pos. set
1562 pt->read_buf_size one less than pt->write_buf_size if there's
1563 an unwritten char at the end of the string. similarly for
1565 (st_resize_port): renamed from st_grow_port.
1566 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
1567 seek from read_end instead of write_end for SEEK_END.
1568 (st_ftruncate): calculate current length using readbuf, not write
1570 (scm_strport_to_string): use read_buf_size for length.
1571 (stfill_buffer): don't re-initialise the readbuf.
1573 1999-07-05 Gary Houston <ghouston@easynet.co.uk>
1575 * strports.c (scm_strport_to_string): new procedure.
1576 (scm_call_with_output_string, scm_strprint_obj): use
1577 scm_strport_to_string.
1578 used SCM_INUM0 instead of SCM_MAKINUM (0) in a few places.
1580 1999-07-08 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1582 * symbols.c (scm_gensym): Bugfix. (Thanks to Johannes Hjorth.)
1584 Fri Jun 25 22:14:32 1999 Greg Badros <gjb@cs.washington.edu>
1586 * smob.c: added scm_make_smob_type_mfpe (), scm_set_smob_mfpe ();
1587 use scm_make_smob_type_mfpe to initialize "free", "flo", "bigpos",
1588 and "bigneg" smob types.
1590 * smob.h: Add do ... while(0) idiom to SCM_NEWSMOB. Added
1591 SCM_RETURN_NEWSMOB macro. Added protos for new functions in
1594 * *.c: Use scm_make_smob_type_mfpe, instead of scm_newsmob, and

1683 1999-06-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1685 * struct.c, struct.h:
1687 In order to support different kinds of deallocation, a destructor

1763 * eq.c, eval.c, list.c, ramap.c, vectors.c: Always write parens
1764 around the condition of an `if', `while', etc., even if the
1765 condition is a macro invocation that expands to something
1766 surrounded by parens. It's more readable.

1769 proper lists, and of the appropriate lengths.
1770 (check_map_args): New function. (Thanks to Greg Harvey for the

1812 vectors without allocating new storage during GC, using
1813 scm_weak_vectors as the head of the chain.
1814 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
1815 instead of stepping through an array.

1822 (scm_igc): Set and clear already_in_gc; abort if it's set at
1825 1999-06-14 Jim Blandy <jimb@savonarola.red-bean.com>
1827 Fix from Gary Houston:
1828 * fports.c (local_seek): Signal an error if the seek fails.
1829 * ports.c (scm_lseek): Don't check return value of port's seek
1830 function; it's its job to signal an error if there's a problem.
1832 1999-06-12 Jim Blandy <jimb@savonarola.red-bean.com>

1841 actually correspond to the changes described below. I got the
1842 ChangeLog entries and the patch from two different places...
1844 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
1846 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
1847 it shows up as terrible performance, as we GC constantly.
1849 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
1850 newline. A bit faster, and definitely hairier.
1851 (scm_read_line): Count newlines here instead.
1853 * strings.c (scm_take_str): New function.
1854 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h

1860 * init.c (scm_init_standard_ports): Request line-buffering on
1861 the standard output port.

1864 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
1865 and there's a newline to be written, flush the port.
1867 Gary Houston's open-buffer port patches:
1869 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
1871 * ports.c: (scm_lseek): clear buffers even if just reading current

1893 ports.c (scm_init_ports): initialise the seek symbols here
1894 instead of in ioext.c.
1895 strports.c (scm_call_with_output_string): start with an empty
1896 string, so seek and ftruncate can be used.
1898 gdbint.c: adjust string port usage.
1900 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
1902 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
1903 equivalent to fflush for the read buffer.

1911 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
1912 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
1913 ptob proc if the read buffer is filled.
1915 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
1917 * ports.h (scm_port): add a rw_random member and replace
1918 reading and writing members with rw_active member.
1919 SCM_PORT_READ/SCM_PORT_WRITE: new values.
1921 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
1923 * ports.h (struct scm_port_table): add writing and reading members
1924 to replace write_needs_seek: it isn't good enough for non-fports.
1925 ports.c, ioext.c, fports.c: corresponding changes.
1926 (struct scm_port_table): give it a typedef and rename to scm_port.
1927 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:

1938 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
1939 signals (it was only being done for handlers installed from Scheme).
1940 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
1941 waiting for input caused an EINTR error from read.
1943 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
1945 * ports.h (struct scm_port_table): make all the char members
1946 unsigned, so they convert to int without becoming negative if large.
1948 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
1950 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
1951 with threads enabled. rename this procedure to
1952 fport_wait_for_input and take a port instead of a fdes.
1953 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
1955 * readline.c (scm_readline): Applied a patch from Greg Harvey to
1956 get readline support working again: use fdopen to get FILE objects.
1958 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
1960 * gc.c (scm_init_storage): install an atexit proc to flush the
1962 (cleanup): the new proc. it sets a global variable which can be
1963 checked by the ptob flush procs to avoid trying to throw
1964 exceptions during exit. not very pleasant but it seems more reliable.
1965 * fports.c (local_fflush): check terminating variable and if set
1966 don't throw exception.
1967 * CHECKME: that the atexit proc is installed if unexec used.
1969 * throw.c (scm_handle_by_message): don't flush all ports here.
1970 it still causes bus errors.
1972 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
1973 and move to ioext.c.
1975 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
1977 * ports.c (scm_char_ready_p): check the port buffer and call the
1978 ptob entry if needed.
1980 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
1981 ptob initialisers. use it in char-ready
1983 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
1985 * vports.c (sfflush): modified to write a char (since softports
1986 currently use shortbuf.)
1988 * fports.c (scm_standard_stream_to_port): moved to init.c and
1991 * init.c (scm_init_standard_ports): make stdout and stderr
1992 unbuffered if connected to a terminal. with stdio they
1993 were line-buffered by default.
1995 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
1998 * ports.h (scm_ptobfuns): change fflush return to void.
1999 change flush proc definitions.
2001 * strports.c (scm_call_with_output_string): get size from
2002 buffer instead of port stream.
2003 (st_flush): new proc.
2005 * ports.h (struct scm_port_table): added write_end member,
2006 as an optimisation. set it where write_buf_size is set.
2008 * ports.h (struct scm_port_table): change stream from void *
2009 back to SCM. SCM presumably must be large enough to hold a
2010 pointer (and probably vice versa but who knows.)
2011 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
2013 (scm_puts): rewritten
2014 * fports.c (local_ffwrite, local_fputs): removed.
2015 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)

2027 * fports.c: set it to local_seek, new procedure.
2030 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
2031 use ptob for seek. take ptob instead of fport arg.
2033 * ports.h (struct scm_port_table): new member write_needs_seek,
2034 replaces reading member in fport struct.
2036 * vports.c (sfgetc): store the getted char into the buffer.
2037 rename to sf_fill_buffer and install it for fill-buffer in ptob.
2038 the Scheme interface is still a procedure that gets a char.
2039 (scm_make_soft_port): set up the port buffer (shortbuf).
2041 * fports.c (local_fgetc, local_fgets): deleted.
2042 * strports.c (stgetc): likewise.

2046 * ports.c (scm_newptob): assign it.
2047 * strports.c (scm_mkstrport): set up the buffer.
2048 put just the string into the stream, not cons (pos stream).
2049 (stfill_buffer): new proc.
2051 * ports.h: fport buffer moved into port table: to be
2052 used for all port types.

2061 scm_getpeername, scm_recv, scm_send, scm_recvfrom,
2063 use SCM_FPORT_FDES. use SCM_OPFPORTP not SCM_FPORTP.
2065 * posix.c (scm_getgroups): use SCM_ALLOW/DEFER_INTS.
2066 (scm_ttyname): use SCM_FPORT_FDES.

2073 (scm_fdes_to_ports): modified.
2074 (scm_fdopen): use scm_fdes_to_port.
2076 * ports.c (scm_init_ports): don't try to flush ports using
2077 atexit(). it's too late, errors will cause SEGV.
2079 * fports.c (scm_fport_buffer_add): new procedure.
2081 * fports.h (SCM_FDES_RANDOM_P): new macro. use it in
2082 scm_fdes_to_port and scm_redirect_port.
2084 * ioext.c (scm_redirect_port): use setvbuf to set buffers in the
2085 new port. reset fp->random.

2088 filesys.c (scm_opendir):
2089 restore defer interrupts while the port is constructed.
2090 (scm_setvbuf): if mode is _IOFBF and size is not supplied,
2091 derive buffer size from fdes or use a default.
2092 (scm_fdes_to_port): use setvbuf instead of creating the buffers
2095 vports.c (various places): use SCM_SSTREAM.
2096 strports.c: likewise.

2247 * strop.c (scm_string_capitalize_x): Use the SCM object `s' in
2248 error messages, not the uninitialized string `str'. Love that
2251 * strop.c (scm_substring_move_x): New function, which can handle
2252 arbitrary overlapping substrings.
2253 (substring-move-left!, substring-move-right!): These are

2327 1999-03-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2329 * numbers.c (isfinite): Define this macro if not defined: Return a
2330 non-zero value if X is finite. (From ISO C 9x standard.)

2359 (scm_system_module_env_p): Assume root environment is no lookup
2362 * debug.c, eval.c, evalext.c, gdbint.c stacks.c:
2363 #include "modules.h".

2383 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2385 Most of this batch of changes is about how to deal with extended
2386 types when an object system is loaded into Guile. A nice object
2387 system is capable of representing Guile's types as class objects.
2389 For example, we want a regular expression to be of class <regex>.
2390 But regular expressions are smobs which aren't under direct
2391 control of the object system, so there has to be some mechanism
2392 which informs the object system that a new class should be created
2393 which can represent the smob type. I call this a "wrapper class".
2395 * objects.c: #include "smob.h";
2396 (scm_class_keyword): Removed. (Class is automatically created by
2398 (scm_smob_class): Array of smob classes indexed by smobnum.
2399 (scm_make_extended_class): "Plugin" function pointer for creation
2400 of wrapper classes for smob and struct types.
2401 (scm_class_of): Handle compiled closures. (Currently regarded as
2403 Use scm_smob_class to handle smob types;
2404 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
2405 through scm_smob_class;
2408 * smob.c (scm_newsmob): Also create a wrapper class if
2409 scm_smob_class has been initialized.
2411 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
2412 type code and smobnum.
2414 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
2415 (scm_struct_table): Weak key table with auxilliary information for
2416 struct types. Currently used for names and wrapper classes.
2417 (scm_struct_ihashq): Hash function for structs.
2418 (scm_struct_create_handle): Get/create entry in scm_struct_table.
2419 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
2420 for accessing names of vtables. The record implementation in
2421 boot-9.scm currently uses the setter to record the name of record
2422 types. When the object system is initialized, it can use this
2423 information to create wrapper classes with suitable names.
2424 (scm_init_struct): Allocate scm_struct_table.
2425 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
2426 (struct tags are a finite resource and we might want to restrict
2427 the use of tags to vtables only. E.g., Goops only uses tags for
2429 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
2431 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
2434 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
2435 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
2436 Used for access of struct table entries.
2438 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
2439 (scm_hash_fold): New procedure. Used to process all entries in a
2440 hash table (in no particular order).
2442 Argh! For the umpteenth time I got compilation errors because of
2443 the "intuitive" name `kw'. This has to have an end:
2445 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
2446 "kw" --> "keywords" everywhere.
2447 (I doubt that this will cause big compatibility problems since the
2448 application interface is unaffected.)
2450 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
2452 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2454 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
2455 column inums to native form.
2457 Improvement of backtraces: Introduces a new stack narrowing
2458 specifier, #t, for the inner cut. (See further in the comments in
2459 stacks.c:narrow_stack ().)

2462 (Used to flag certain system procedures which shouldn't turn up in
2465 * eval.c (scm_sym_system_module): New symbol. (Used to flag
2466 modules which aren't "user" modules and the code of which
2467 shouldn't turn up in backtraces.)

2470 Extract the lookup closure from an environment.
2471 (scm_system_module_env_p): New function: Return non-#f if MODULE

2477 * debug.c (scm_procedure_name): Use name property in the default
2480 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
2482 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
2484 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
2485 procedure throughout.
2487 * print.c (scm_iprin1): Removed extraneous space when printing
2488 procedure-with-setters.
2490 Entity and operator setter slots were introduced as a complement
2491 to the <procedure-with-setter> type in order to support entities
2492 and operators with setters in a reasonable and efficient way.
2493 * procs.c (scm_procedure, scm_setter): Handle entity and operator
2496 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.

2508 * objects.h (SCM_OBJ_CLASS_REDEF): New macro: Find class slots
2509 directly through the instance.
2511 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
2513 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
2514 scm_struct_i_flags instead of scm_vtable_index_layout!
2516 * list.c (scm_list_star): New procedure.
2518 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

2548 (scm_init_readline): Call init_bouncing_parens.

2594 strports.h, symbols.h, unif.h: Update variable declarations and
2595 function prototypes for above changes.
2597 * dynl.c, dynl-dld.c, dynl-dl.c, dynl-shl.c (sysdep_dynl_link,
2598 sysdep_dynl_unlink, sysdep_dynl_func): Arguments FNAME, SUBR, and
2599 SYMB now point to const.
2601 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2603 * print.c (scm_iprin1): Use scm_procedure_name instead of
2604 scm_procedure_property for compiled closures.
2606 * tags.h (scm_tc7_pws): New procedure type. Four representations
2607 for procedure-with-setters were considered before selecting this
2610 1. A closure where the CODE and ENV slots are used to represent
2611 the getter and a new SETTER slot is used for the setter. The
2612 original getter is stored as a `getter' procedure property. For
2613 closure getters, the CODE and ENV slots contains a copy of the
2614 getter's CODE and ENV slots. For subr getters, the CODE contains
2617 2. A compiled closure with a call to the getter in the cclo
2618 procedure. The getter and setter are stored in slots 1 and 2.
2620 3. An entity (i.e. a struct with an associated procedure) with a
2621 call to the getter in the entity procedure and the setter stored
2622 in slot 0. The original getter is stored in slot 1.
2624 4. A new primitive procedure type supported in the evaluator. The
2625 getter and setter are stored in a GETTER and SETTER slot. A call
2626 to this procedure type results in a retrieval of the getter and a
2627 jump back to the correct eval dispatcher.
2629 Representation 4 was selected because of efficiency and
2632 Rep 1 has the advantage that there is zero penalty for closure
2633 getters, but primitive getters will get considerable overhead
2634 because the procedure-with-getter will be a closure which calls
2637 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
2638 <procedure-with-setter>, but together with rep 2 it suffers from a
2639 three level dispatch for non-GOOPS getters:
2641 cclo/struct --> dispatch proc --> getter
2643 This is because the dispatch procedure must take an extra initial
2644 argument (cclo for rep 2, struct for rep 3).
2646 Rep 4 has the single disadvantage that it uses up one tc7 type
2647 code, but the plan for uniform vectors will very likely free tc7
2648 codes, so this is probably no big problem. Also note that the
2649 GETTER and SETTER slots can live directly on the heap, using the
2650 new four-word cells.
2652 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,
2653 SCM_SETTER): New macros.

2672 * evalext.c, evalext.h (scm_m_generalized_set_x): New memoizing
2674 (scm_init_evalext): Call scm_make_gsubr for
2675 scm_m_generalized_set_x.

2679 * eval.h: Declare scm_s_set_x, scm_sym_set_x;
2681 * eval.c: Renamed "set" --> "set_x" in various names for
2682 consistency of name correspondence between Scheme and C;
2683 Renamed scm_i_set_x --> scm_sym_set_x and made global.
2684 Renamed s_set_x --> scm_s_set_x and made global.
2686 1999-01-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2688 * random.c (scm_i_random_bignum): Made independent of endianness.

2706 scm_rstate from seed.
2707 (scm_copy_random_state, scm_seed_to_random_state): New functions.
2708 (scm_make_random_state): Removed.
2710 * random.c (scm_make_random_state): Use scm_i_make_rstate().

2714 * random.c: Bugfix: Retrieve and store most significant 32 bits in
2715 different order if the machine is bigendian.

2721 from first arg before equal elements in second arg in result.
2722 (scm_merge_list_step): Bugfix: Don't presume that arguments in a C
2723 function call are executed in a well defined order.
2725 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
2727 * alloca.c (alloca): Cast value returned by malloc. (Thanks to
2730 1999-01-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2732 * random.c: Removed alloca includes.
2734 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
2736 * Makefile.in: This changed, for some reason I don't really
2737 understand, when I ran automake in the top level directory. This
2738 may be contamination by Cygnus internal releases. If you re-run
2739 automake and this change gets reverted, don't worry about it.
2741 1999-01-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2743 * sort.c, sort.h: New files: Implement slib's and scsh's sort
2744 interfaces. Author: Roland Orre.

2756 * random.c, random.h: New files: Random number support.
2757 Interface same as slib's.
2759 * Makefile.am: Added random.c, random.h, random.x.
2761 * init.c: #include "random.h";

2764 1998-12-23 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2766 * Makefile.am: New files: guardians.c, guardians.x, guardians.h
2768 * guardians.c, guardians.h (scm_make_guardian,
2769 scm_guardian_gc_init, scm_guardian_zombify, scm_guard,
2770 scm_get_one_zombie, scm_init_guardian): This is an implementation
2771 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
2772 David Eby (1993) "Guardians in a Generation-Based Garbage
2773 Collector" ACM SIGPLAN Conference on Programming Language Design
2774 and Implementation, June 1993 ftp://ftp.cs.indiana.edu
2775 /pub/scheme-repository/doc/pubs/guardians.ps.gz
2776 Author: Michael N. Livshin.
2778 * gc.h (SCM_MARKEDP, SCM_NMARKEDP): New macros.

2785 1998-12-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2787 * macros.c (scm_makacro, scm_makmacro, scm_makmmacro): Added
2790 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2792 Move the procedure slots of entities to invisible slots (so that
2793 we can have operator class objects which themselves are entities).
2794 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
2795 SCM_STRUCTF_ENTITY): New constants.
2797 * struct.c (scm_make_struct): Allocate "invisible" room for
2798 procedures if SCM_STRUCTF_ENTITY is set in vtable.
2800 * gc.c (scm_gc_mark): Mark entity procedures.
2802 * struct.c, struct.h (scm_alloc_struct): Renamed from alloc_struct

2807 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0,
2808 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
2810 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
2812 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
2813 of syntactic forms, similar to SCM_PROC.
2814 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
2815 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
2816 for the name symbols when needed.
2818 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
2820 * Makefile.in: Regenerated.
2822 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
2824 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
2825 take the address of _into; it might be a register. Just have
2826 scm_debug_newcell return the new cell.
2827 * gc.c (scm_debug_newcell): Just return the new cell, instead of
2828 taking the address of a place to store it as an argument.
2829 * gc.h (scm_debug_newcell): Change declaration.
2830 (Thanks to Greg Harvey.)
2832 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2834 * ramap.c (array-copy-in-order!, array-map-in-order): New names.
2835 Replaces old names serial-array-copy! and serial-array-map!.

2841 * smob.c (freeprint): New function.
2842 (freecell): Use it to print freed objects, for slightly easier
2845 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2847 * backtrace.c (display_frame): Made more robust. Doesn't throw an
2848 error if no source properties can be found for a frame. (Thanks
2849 to Christian Lynbech.)
2851 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2853 * objects.h: Removed slots direct_supers and direct_slots from the
2854 definitions of the rudimentary classes described by objects.h.
2856 * objects.c, objects.h (scm_entity_p): New procedure. Together
2857 with the predicates scm_procedure_p and scm_struct_p, this
2858 predicate makes it possible to differ between structs, entities
2861 * modules.c, modules.h (scm_resolve_module): New function.
2863 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2865 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
2866 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
2869 * objects.c (scm_entity_p): New procedure.
2871 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
2872 for asubrs, rpsubrs, lsubrs and lsubr_2s.
2874 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2876 * procprop.h (scm_i_procedure_arity): Added declaration.
2878 * procprop.c (scm_i_procedure_arity): Made global; New code to
2879 handle operators and entities.
2880 (scm_procedure_property): No need to call scm_procedure_p since
2881 scm_i_procedure_arity now does all necessary type checking.
2882 Added #include "objects.h".
2884 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
2885 s_add_hook_x --> s_remove_hook_x.
2886 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
2887 Added #include "procprop.h"
2889 * feature.c, feature.h (scm_reset_hook_x): New procedure.
2890 (scm_make_hook): Optional argument defines number of arguments to
2892 (scm_make_named_hook): Take number of args as second arg.
2893 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
2894 boot-9.scm for a while); First arg is the hook. The rest are
2895 arguments passed on to the hook procedures.
2897 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
2899 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
2900 scm_logbit_p): Do the computation in ulongs. This is not as nice
2901 as doing it in bignums, but at least it's good enough for
2902 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
2904 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
2905 subexpressions. (Thanks to Charbel Jacquin.)
2907 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
2909 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
2910 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
2911 (scm_make_named_hook): New function.
2913 * feature.c: Added #include "eval.h".
2915 * modules.c (scm_make_module): Beautify the module.
2917 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2919 * modules.c, modules.h: New files: C interface to modules. (This
2920 is necessary in order to interface the object system to Guile
2921 properly. The guts of these modules will be replaced by the new
2922 module system in the future.)
2924 * init.c: Added #include "modules.h"
2925 (scm_boot_guile_1): Call scm_init_modules.
2926 (invoke_main_func): Call scm_post_boot_init_modules.
2928 * Makefile.am: Added modules.c, modules.x, modules.h.
2930 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
2932 * procs.c: #include "objects.h"
2933 (scm_procedure_p): Return #t also on structs which are operators.
2935 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
2936 <operator-metaclass> and <entity-class> to <standard-class>,
2937 <operator-class> and <entity> in order to conform with STKlos
2940 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
2941 which isn't an operator.
2942 (SCM_APPLY): Ditto, but jump to badproc.
2944 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
2946 * eval.c (SCM_CEVAL): Allow structs implanted in code.
2947 Previously, structs implanted in code were interpreted as forms
2948 the operator of which was a gloc. We solve this by checking for
2949 the zero in the emulated vcell in the struct vtable. Since
2950 implanted structs always will look like forms with a gloc
2951 operator, execution will only be slowed down by maximally one
2952 extra test-and-branch per application.
2954 * evalext.c (scm_definedp): Removed check for isyms; Added a
2955 second optional argument: It is now possible to supply an
2956 evaluation environment in which to look for the symbol.
2958 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2960 * readline.c (scm_init_readline): Set
2961 rl_basic_word_break_characters. (Thanks to Ian Grant.)
2963 * coop.c (coop_condition_variable_wait): Removed
2964 (coop_condition_variable_wait_mutex): Folded logic of
2965 coop_mutex_unlock into coop_condition_variable_wait_mutex to
2966 prevent condvar signal lossage. Previously, another thread could
2967 start to run after unlocking the mutex but before putting the
2968 current thread on the wait queue. If that thread then would
2969 signal the first, the signal would be lost. (Thanks to Christian
2972 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2974 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
2977 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2979 * objects.c (scm_i_make_class_object): Renamed from
2980 make_class_object; exported; error checking moved to
2981 scm_make_class_object and scm_make_subclass_object.
2982 (scm_make_class_object, scm_make_subclass_object): Use
2983 scm_i_make_class_object.
2984 (scm_make_subclass_object): Let the subclass have same metaclass
2987 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2989 * debug.c (scm_debug_options): Bugfix: Set the value of
2990 scm_stack_checking_enabled_p after setting debug options;
2991 #include "stackchk.h". (Thanks to Richard Polton.)
2993 1998-11-13 Radey Shouman <rshouman@metro2000.com>
2995 * unif.c (scm_array_contents): removed unnecessary test for 0
2998 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3000 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
3001 Replaced by macro `collect' in boot-9.scm.
3003 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3005 * eval.c (scm_copy_tree): Copy source properties if existent.
3007 * debug.c (scm_start_stack): Copy source when evaluating. (If we
3008 don't, we may end up passing memoized source to a transformer.)
3010 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3012 * stack.c (get_applybody): Help function which lookups the first
3013 body form of the apply closure.
3014 (read_frames): Prevent the source of the first form of the apply
3015 closure from being recorded. This would only be confusing.
3017 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
3018 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
3020 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
3022 * stacks.c (read_frame): Bugfix: Removed lingering `else'
3024 (read_frames): Use SCM_MACROEXPP.
3026 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3028 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
3029 don't contain interesting information since all arguments are
3030 present in the frame which applies the compiled closure anyway.);
3031 Skip the transformer application frames.
3033 * print.c (scm_iprin1): Print gsubrs as primitives.
3035 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3037 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
3039 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
3040 that we can identify these in a backtrace. (This change doesn't
3041 introduce any significant speed penalty.)
3043 * eval.c: Added note about `serial-map' using scm_map.
3045 * read.c, read.h (scm_read_options, scm_read_opts): Removed
3046 readline options. They should reside in their own options array.
3048 * readline.c, readline.h (scm_readline_options,
3049 scm_readline_opts): Moved readline options here.
3051 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3053 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
3054 SCM_ROCHARS instead of SCM_CHARS.
3056 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
3057 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
3059 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3061 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
3062 This is quite important since the latter clears the
3063 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
3064 every single character read...
3066 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3068 * print.c (scm_iprin1): Removed suspect looking (and indeed
3069 malevolent) semicolon after test for user supplied closure print
3070 procedure. (Thanks to Telford Tendys.)
3072 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
3073 (scm_memq, scm_memv, scm_member): Do argument checking *before*
3074 starting to search the list. Removed call to sloppy_mem_check.
3076 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
3077 procedures: Same as scm_delq_x et al, but delete maximally one
3080 * options.c (scm_options, scm_init_options): GC-protect option
3081 values of type SCM. (Thanks to Telford Tendys.)
3083 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3085 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
3086 make sure that there always is a "real" scm_lookupcar.
3088 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3090 * read.c, read.h (scm_read_opts): New read options
3091 "history-length" and "history-file".
3092 (scm_read_options): Stifle history to history length.
3094 * readline.c (scm_read_history, scm_write_history): New procedures.
3096 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3098 * eval.h (scm_macro_eval_x): Removed declaration.
3100 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
3101 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
3102 Renamed and made global.
3104 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
3105 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
3107 * evalext.c, evalext.h: New files. Contain non-R5RS things
3108 having to do with evaluation.
3110 * evalext.c (scm_serial_map): New procedure: Version of `map'
3111 which guarantees that the procedure is applied to the lists in
3113 (scm_m_sequence_to_list): New syntax: Version of `begin' which
3114 returns a list of the results of the body forms instead of the
3115 result of the last body form.
3116 (scm_definedp, scm_m_undefine): Moved from eval.c
3118 * evalext.h (scm_m_sequence_to_list): Added declaration.
3120 * macros.c, macros.h: New files.
3121 (scm_procedure_to_syntax, scm_procedure_to_macro,
3122 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
3123 scm_macro_name, scm_macro_transformer): Moved from eval.c
3124 (scm_make_synt): Moved from eval.c
3126 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
3128 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
3131 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
3133 * debug.c, print.c: Added #include "macros.h".
3135 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3137 This change adds the ability to use `unread-char' multiple times
3138 without interspersed reads and adds the new procedure
3139 `unread-string'. The change is optimized for the common case of
3140 unreading a single character. This is also the reason behind the
3141 choice to store characters in the port itself: in most cases no
3142 extra malloc is required.
3144 The amount of code in some macros in ports.h has been increased to
3145 the extent that they would fit better as C functions, but, since
3146 this code belongs to the port representation, such functions
3147 should be placed in ports.c which would cause calls back and forth
3148 between ports.c and genio.c. That is not good for performance.
3149 Also, keeping them as macros allows the compiler to do some
3150 optimizations which are needed to make the current interface
3151 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
3153 One benchmark (Guile startup time) indicates an increase of
3154 loading speed of 1%. Another (reading (using `read') boot-9.scm
3155 10 times) shows no change in performance.
3157 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
3158 made to find a beautiful solution.)
3160 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
3161 (SCM_TRY_CLRDY): New macro: Only clear the first unread
3162 character. (SCM_CLRDY clears all.)
3163 (SCM_N_READY_CHARS): New macro: Returns number of unread
3164 characters in a port. Returns wrong answer if SCM_CRDYP is false.
3165 (struct scm_port_table): New fields: `entry' contains port table
3166 index, `cp' points to last unread char, `cbuf' is the buffer for
3167 unread chars, `cbufend' points after end of the character buffer.
3169 * ports.h, ports.c (scm_unread_string): New procedure.
3170 (scm_grow_port_cbuf): New function.
3172 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
3174 (scm_generic_fgets), fports.c (local_fgets): Use a loop
3175 to read unread characters. Use SCM_TRY_CLRDY instead of
3178 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
3180 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
3182 * genio.c, genio.h (scm_ungets): New function.
3184 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
3187 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3189 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
3190 declarations. (Thanks to Russ McManus.)
3192 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3194 * numbers.c (num2long): As a software archeologist, I'm proud of
3195 this finding! :) Preliminary dating suggests an almost 4 year old
3196 remnant from the SCM ancestor. The sample has been removed from
3197 the finding site and is now safely stored in the repository.
3199 * numbers.h: Removed prototype for num2long.
3201 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
3203 * gh_data.c (gh_scm2doubles): Make it possible to pass result
3204 array as second arg.
3205 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
3206 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
3207 * gh.h: Updated and added prototypes.
3209 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
3211 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
3213 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
3215 * guile-snarf.in: Never generate an empty file. (Thanks to
3218 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
3219 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
3220 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
3221 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
3222 gh_new_procedure5_0): Specify argument types, to appease C++
3223 compilers. (Thanks to Brad Bowman.)
3225 Bug reports from Russ McManus:
3226 * guile-snarf.in: If the CPP environment variable is set, use that
3227 as the C preprocessor, instead of the preprocessor autoconf
3229 * snarf.h (SCM_PROC): Cast the function pointer passed to
3230 scm_make_gsubr, to satisfy C++.
3232 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
3233 Use the handler passed, instead of ignoring it and using
3234 gh_standard_handler. (Thanks to Etienne Bernard.)
3236 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
3238 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
3241 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>

3258 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
3261 * script.c (scm_compile_shell_switches): Define
3262 use-emacs-interface in the root module, so the repl code can see
3263 it. See today's change to top-repl in ice-9/boot-9.scm.
3265 * filesys.c (set_element, get_element): Make sure that `element'
3266 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
3267 Boekemeier and Jorgen "forcer" Schaefer.)
3269 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
3271 * chars.c (scm_charnames): In ASCII character name table, make
3272 newlines print as #\newline by default, not #\nl.
3274 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
3275 alphabetical order. Oh thrills. But it helps me know how far
3276 along in the compilation I am.
3277 * Makefile.in: Regenerated.
3279 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3281 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
3282 #bytes(...) to #y(...), and syntax for short vectors from
3283 #short(...) to #h(...). This may seem nutty, but, like the other
3284 uniform vectors, byte vectors and short vectors want to have the
3285 same print and read syntax (and, more basic, want to have read
3286 syntax!). Changing the read syntax to use multiple characters
3287 after the hash sign breaks with the conventions used in R5RS and
3288 the conventions used for the other uniform vectors. It also
3289 introduces complexity in the current reader, both on the C and
3290 Scheme levels. (The Right solution is probably to change the
3291 syntax and prototypes for uniform vectors entirely.)
3293 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
3295 Don't use local_fgets on sockets; ftell doesn't work on sockets.
3296 (Thanks to Jorgen "forcer" Schaefer.)
3297 * ports.h (SCM_NOFTELL): New flag.
3298 * fports.c (local_fgets): If it's set, use the generic fgets.
3299 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
3301 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3303 * script.c (scm_compile_shell_switches): Add handling of -q switch
3304 (inhibit loading of user init file).
3305 (scm_shell_usage): Add usage text for -q switch.
3306 (scm_compile_shell_switches): Always load user init file first if
3307 it is loaded at all.
3309 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
3311 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
3312 and is now broken under NetBSD. I can't fathom what it's trying
3313 to do, so I've replaced it with something that I do understand,
3314 which seems to work, and which isn't broken on NetBSD. "Progress?
3315 You Decide." (Thanks to Perry Metzger.)
3317 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
3318 signed/unsigned comparison.
3320 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
3322 Warning fixes from Greg Harvey:
3323 * unif.c (scm_array_set_x): initializer for pos
3324 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
3325 * struct.c (scm_struct_ref, scm_struct_set_x): Added
3326 initializers for field_type, since EGCS so desparately wants to
3328 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
3329 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
3330 when GUILE_DEBUG is defined.
3331 * dynwind.h (scm_wind_chain): Same.
3332 * ports.h (scm_pt_size, scm_pt_member): Same.
3333 * print.h (scm_current_pstate): Same.
3334 * procs.h (scm_make_cclo): Same.
3336 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
3338 Handle short and long long uniform arrays properly. (Thanks to
3340 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
3341 raeql_1): Add cases for scm_tc7_svect (short vectors) and
3342 scm_tc7_llvect (long long vectors).
3344 Change the way libguile and boot-9.scm are timestamped, to try to
3345 get rid of these spurious mismatch warnings. Now both
3346 libguile/versiondat.h and ice-9/version.scm are generated directly
3347 by the configuration process, rather than having version.scm
3348 generated directly, and libguile/versiondat.h generated by the
3349 Makefile, which is generated by configure. It seems that
3350 sometimes the Makefile would change, but versiondat.h depends on
3351 Makefile.in, not Makefile, so it wouldn't get rebuilt.
3352 * Makefile.am (versiondat.h): Target removed; this is generated
3353 directly by the configure script now.
3354 (BUILT_SOURCES): Remove versiondat.h.
3355 * versiondat.h.in: New file, transformed by the configure script
3357 * Makefile.in: Regenerated.
3359 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
3360 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
3361 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
3362 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
3363 if we want to use them in a header file some day, we can. (Thanks
3364 to Michael Livshin.)
3366 * stime.c (scm_get_internal_real_time): Do the arithmetic using
3367 SCM numbers, so we won't have rollover problems; the range of a
3368 signed long in milliseconds is about 25 days. (Thanks to Karl
3371 Don't redefine sleep and usleep; fix this problem now.
3372 * coop.c (sleep, usleep): Remove declarations; we don't use or
3373 redefine these any more.
3374 (scm_thread_usleep, scm_thread_sleep): New functions which do the
3375 job of usleep and sleep in a thread-friendly way. We can use
3376 these in the rest of Guile. Define versions for systems both with
3377 and without iselect.
3378 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
3379 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
3380 we're just using it, not redefining it, we can use a K&R style
3382 (sleep): Declare this, too, if the system hasn't.
3383 (scm_sleep, scm_usleep): Use scm_thread_sleep and
3384 scm_uthread_sleep if they're available; otherwise, just call the
3386 * scmconfig.h.in: Regenerated.
3388 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
3390 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
3392 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
3394 * threads.c: Doc fix.
3396 The argument type of usleep varies from system to system,
3397 as does the return type. We really shouldn't be redefining usleep
3398 at all, but I don't have time to clean that up before the 1.3.
3399 release. It's on the schedule for afterwards. (Thanks to Julian
3401 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
3403 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
3404 * scmconfig.h: Regenerated.
3406 * simpos.c (scm_software_type): Procedure deleted. This isn't the
3407 right way to handle system variation. Autoconf's approach is the
3409 * simpos.h (scm_software_type): Declaration deleted.
3411 * script.c (scm_find_executable): Don't test if unix is #defined
3412 here; first, NetBSD doesn't #define it, and second, it's the wrong
3413 way to go about these things. (Thanks to Perry Metzger.)
3414 (dld_find_executable): Delete this MSDOS support code. This isn't
3415 the way we want to support this; it needs to be rethunk at a
3418 * genio.c (scm_do_read_line): Don't just politely check that the
3419 line was either non-empty or EOF. Abort if it's empty and not
3422 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
3424 * scmconfig.h.in: Regenerated.
3426 * libguile.h: Don't omit the dynamic linking functions. (Thanks
3429 * genio.c (scm_do_read_line): Count lines correctly when the file
3430 doesn't end in a newline.
3432 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
3434 * genio.c (scm_do_read_line): Maintain the line count correctly.
3435 (Thanks to Harvey J. Stein and Greg Harvey.)
3437 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
3440 * numbers.c (big2str): Protect t from garbage collection until
3441 we're done. (Thanks to Gary Houston.)
3443 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
3445 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
3447 * Makefile.in: Regenerated.
3449 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
3450 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
3453 Do magic to mix reads and writes on stdio FILE-based ports.
3454 (Thanks to Christian Lynbech.)
3455 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
3457 (pre_read, pre_write): New functions.
3458 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
3459 local_fputs): Call them.
3460 (local_fflush): Mark the port as ready for reading and writing.
3461 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
3462 flags on new port objects. This might not be accurate --- who
3463 knows what state the FILE * is in when we get it --- but it won't
3464 do extraneous calls to fflush or fseek, so it's no worse than the
3465 behavior before this change.
3466 * ports.h: Add comment.
3468 Centralize the creation of port objects based on stdio FILE * in
3469 fports.c; don't just throw them together anywhere.
3470 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
3471 what the rest of Guile wants. Don't set the revealed count;
3472 that's only appropriate for stdin, stdout, stderr.
3473 (scm_standard_stream_to_port): This function does set the revealed
3475 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
3476 not scm_stdio_to_port.
3477 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
3478 * fports.c (scm_open_file): Same.
3479 * posix.c (scm_pipe): Same.
3480 * socket.c (scm_sock_fd_to_port): Same.
3481 * ioext.c (scm_fdopen): Same.
3482 (scm_freopen): Moved from here to...
3483 * fports.c (scm_freopen): ... here. This is really something that
3484 munges the internals of an fport, so it should go here.
3485 * fports.h (scm_stdio_to_port): Adjust prototype.
3486 (scm_standard_stream_to_port, scm_freopen): New protoypes.
3487 * ioext.h (scm_freopen): Prototype removed.
3489 * filesys.c (set_element, get_element): This can work on both pipe
3490 and file ports, so use SCM_FPORTP to typecheck, instead of testing
3493 * scmconfig.h.in: Regenerated.
3495 Change the definition of the functions in scm_ptobfuns so that
3496 they get passed the port object, not the port's stream.
3497 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
3498 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
3499 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
3500 Pass the port itself to the scm_ptobs function.
3501 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
3502 scm_generic_fgets): Same.
3503 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
3504 getc_void_port, fgets_void_port, close_void_port): Just change the
3505 argument names; these functions don't really do anything.
3506 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
3507 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
3508 port as an argument, and use SCM_STREAM to get the stdio FILE *.
3509 Also, use prototyped definitions, and get rid of the extra
3511 (scm_fptob, scm_pipob): We don't need casts here any more.
3512 * strports.c (prinstpt): Use prototype declarations.
3513 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
3514 and use SCM_STREAM to get the string info. Also, use prototyped
3515 definitions, and get rid of the extra declarations.
3516 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
3519 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
3520 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
3522 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
3523 scm_fgets, for consistency.
3524 (scm_fptop, scm_pipob): References updated.
3526 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
3528 Include the source location in error messages for scripts.
3529 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
3530 stack is still there when we catch the error.
3531 * throw.c (handler_message): If we are handling an error with a
3532 message, then put together the proper arguments and call
3533 scm_display_error, instead of scm_display_error_message. That
3534 displays source location, if it can find it.
3536 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
3538 * gc.c (scm_unprotect_object): Change this so that calls to
3539 scm_protect_object and scm_unprotect_object nest properly.
3540 (scm_protect_object): Doc fixes.
3542 * strings.c (scm_string_set_x): Require the argument to be a
3543 writable string, not a substring or a symbol.
3544 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
3545 (Thanks to John Redford and Charbel Jacquin.)
3547 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
3549 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
3551 * eval.c (safe_setjmp): Remove this misunderstanding.
3552 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
3555 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
3557 * libguile.h: Mark these as C declarations, for compilation by C++
3560 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
3561 __cplusplus clause. I seriously doubt this ever worked the way
3562 the author seems to have intended.
3564 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
3566 Utterly needless cleanups to hopelessly messy code.
3567 * ports.c: Doc fixes.
3568 (scm_fflush): Moved to ...
3569 * genio.c (scm_fflush): ... here, amongst all the other port
3570 method invocation functions.
3571 * genio.h, ports.h: The prototype moves too.
3573 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
3575 * backtrace.c (display_error_body): The current frame does not
3576 always have a parent frame; consider a function called directly
3577 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
3580 * alloca.c (alloca): Undo yesterday's changes, and simply call
3581 malloc directly for storage, and abort if we don't get what we
3582 want. The situation is much simpler --- just call malloc. Emacs
3583 has bizarre/evil requirements (signal handlers might malloc unless
3584 you set this global flag, so you have to set the flag around all
3585 calls to malloc) which we are certainly not going to conform to,
3586 so we can do the simple and obvious thing.
3588 * coop.c (coop_condition_variable_wait): Make this function
3589 static. It's only useful internally --- you should never just
3590 wait on a condition variable.
3591 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
3593 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3595 * unif.c (scm_array_set_x): Accept any kind of number as an
3596 element for a uniform vector of doubles. This is more consistent
3597 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
3599 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
3600 works; I can't conveniently test it myself. (Thanks to Dvid
3601 Tillman for the bug report.)
3603 * init.c: Doc fixes.
3605 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
3606 from here, not from scm_compile_shell_switches (which is a pretty
3607 dumb place to do it).
3608 (scm_load_startup_files): New function.
3609 (scm_ice_9_already_loaded): Variable moved to here from script.c.
3610 * script.c (scm_compile_shell_switches): Don't load the startup
3612 (scm_ice_9_already_loaded): Variable moved.
3613 * init.c (scm_load_startup_files): Prototype for new function.
3614 * gh_init.c (gh_enter): Doc fix.
3616 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3618 Some anti-warning changes from Greg Harvey.
3619 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
3620 warnings when it doesn't understand our NORETURN declarations in
3622 * posix.c (scm_mknod): Similar.
3624 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3626 * posix.c (scm_getpwuid): If we can't find an entry, return our
3627 own message, instead of using scm_syserror --- the getpwMUMBLE
3628 functions don't set `errno' to anything interesting.
3630 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3632 Get rid of warnings from the cooperative threading system.
3633 * threads.h (scm_single_thread_p, scm_yield,
3634 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
3635 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
3636 scm_wait_condition_variable, scm_signal_condition_variable): Add
3637 prototypes for these Scheme-visible functions.
3638 * coop-defs.h (coop_next_runnable_thread,
3639 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
3640 Prototypes for these here, even though they're from iselect.c.
3641 (coop_condition_variable_wait, coop_join): Add prototypes.
3642 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
3643 scm_threads_free_condvar): Make these smob functions static.
3644 * coop-threads.h (coop_init): Give this a real prototype.
3645 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
3646 (coop_next_runnable_thread): No need to provide prototype; it's in
3649 * scmconfig.h.in: .detarenegeR
3651 * iselect.c, threads.c: Doc fixes.
3653 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3655 * Makefile.in: Regenerated with a patched automake, to get
3656 dependency generation right when using EGCS.
3658 * inet_aton.c (inet_aton): Add prototype, to remove compiler
3659 warning. (Thanks to Robert Pluim.)
3661 * inet_aton.c (inet_aton): Reassure the compiler that the
3662 arguments to the <ctype.h> macros are all unsigned characters, not
3665 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3667 Getting rid of more warnings...
3668 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
3669 today's change to ../configure.in.
3670 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
3671 * scmconfig.h.in: Regenertaded.de.,.__
3672 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
3673 (scm_localtime, scm_mktime): Use a const char * to manipulate the
3676 * readline.c: Doc fix.
3677 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
3678 * readline.h (scm_filename_completion_function): Add prototype.
3679 (scm_init_readline): Make this into a prototype.
3681 * readline.c (scm_filename_completion_function): Use SCM_PROC to
3682 declare this, instead of calling scm_make_subr manually.
3684 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
3686 * readline.h (scm_init_readline): Add prototype for this.
3687 (scm_init_readline): Make this a real prototype.
3689 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
3691 Warning fixes from Maciej Stachowiak:
3692 * backtrace.h (scm_display_application, scm_backtrace): Add
3694 * debug.c (scm_m_start_stack): Make this function static.
3695 * fluids.h (scm_fluid_p): Add prototype.
3696 * procprop.c (scm_i_procedure_arity): Make this function static.
3697 * regex-posix.c (scm_regexp_error_msg): Make this function static.
3698 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
3699 * root.h (scm_dynamic_root): Add external prototype.
3700 * scmsigs.h (scm_usleep): Add external prototype.
3701 * script.h (scm_init_script): Use prototype, not K&R decl.
3702 * stacks.h (scm_stack_id): Add external prototype.
3703 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
3705 1998-09-30 Mark Galassi <rosalia@cygnus.com>
3707 * gh.h: took out the definitions of vset and vref, since they are
3708 replaced by the proper vector routines that correspond to the R4RS
3711 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
3713 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
3714 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
3715 third argument, a C expression that should result in a SCM value,
3716 which is used to initialize the variable. Reimplemented
3717 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
3720 * version.h (scm_libguile_config_stamp): Add prototype.
3721 (From Maciej Stachowiak.)
3723 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
3725 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
3726 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
3728 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
3730 * print.c (scm_iprin1): Rather than having one i, and using it in
3731 several places, declare a fresh i local to each block where it is
3732 used, and give it a signedness appropriate to its use in each case.
3733 (scm_iprlist): Same.
3735 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
3736 comparison warnings.
3738 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
3739 signed/unsigned clashes.
3741 * posix.h (scm_tmpnam): Added prototype.
3743 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
3744 scm_make_subclass_object): Add external prototypes.
3746 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
3747 comparison is okay here.
3749 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
3751 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
3752 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
3754 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
3757 * load.c (swap_port): Make this function static.
3759 * load.c (scm_search_path): Make max_path_len and max_ext_len
3760 unsigned, since they're compared against string sizes.
3762 * load.c (init_build_info): Make i unsigned.
3764 * ioext.h (scm_read_line): Add prototype.
3766 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
3767 scm_hash_fn_remove_x): Make hash bucket index local variable k
3768 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
3769 accurately as possible.
3771 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
3772 comparisons, and range checking to make sure those casts are
3775 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
3776 signed/unsigned comparisons.
3778 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
3779 avoid signed/unsigned comparisons.
3780 * smob.h (scm_numsmob): Change extern declaration to match.
3782 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
3783 avoid signed/unsigned comparisons.
3784 * ports.h (scm_numptob): Change extern declaration to match.
3785 (scm_current_load_port, scm_set_port_line_x,
3786 scm_set_port_column_x): New prototypes.
3788 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
3789 test code, and it causes warnings.
3791 * gh.h (gh_int2scmb, gh_uniform_vector_length,
3792 gh_uniform_vector_ref): Added prototypes.
3794 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
3795 debugging support unconditionally. That's backtrace.c, stack.c,
3796 debug.c, and srcprop.c.
3797 (EXTRA_libguile_la_SOURCES): Omit those from here.
3798 * Makefile.in: Regenerated.
3800 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3802 * options.c (scm_options): Bugfix: Allow empty list of options!
3804 * debug.c, debug.h (scm_single_step): Removed.
3805 (scm_with_traps): New procedure. This procedure could easily be
3806 written in Scheme but needs to be highly optimized.
3808 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
3810 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
3811 Check SCM_TRAPS_P before trapping.
3813 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
3815 Changes to avoid signed/unsigned comparison warnings.
3816 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
3817 (scm_gc_sweep): Make n and j local to the blocks they're used in,
3818 so they can have appropriate types for each application. Make i
3819 signed. Use initializers in some spots. I'll probably pay for
3821 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
3822 (scm_must_realloc): Make nm unsigned.
3823 (init_heap_seg): Make new_seg_index and n_new_objects signed.
3824 (scm_init_storage): Use prototype-style definition, and make the
3826 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
3827 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
3829 * filesys.c (scm_readlink): Make local vars rv and size ints, to
3830 avoid signed/unsigned comparison warnings, and because the return
3831 value of readlink may be -1. Don't bother casting the third
3832 argument to readlink.
3834 * filesys.c (scm_dirname, scm_basename): Move these to their own
3835 page, at the end of the file.
3836 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
3838 * eval.h (scm_eval_options_interface): Add external prototype for this.
3839 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
3841 * eval.c (scm_lookupcar1): Make this static.
3843 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
3844 Make these prototype declarations, not K&R-style.
3846 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
3847 unsigned comparison warning.
3849 * appinit.c: File removed. It had a single function in it, empty,
3850 whose reason for existence is explained in no documentation or
3851 comment. I think it's there as a default for some Tcl-style
3852 initialization, but Tcl abandoned that approach a while ago.
3853 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
3854 (BUILT_SOURCES): Remove appinit.x.
3855 * Makefile.in: Regenerated.
3857 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3859 * Makefile.in: Regenerated using the last public version of
3860 automake, not the hacked Cygnus version.
3862 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
3864 Remove Totoro kludge.
3865 * Makefile.in, scmconfig.h.in: Regenerated.
3866 * init.c, readline.c: Don't check if TOTORO is #defined.
3868 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
3870 * Makefile.am: Adjust for new thread configuration system.
3871 (INCLUDES): Include the value of THREAD_CPPFLAGS.
3872 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3874 (THREAD_LIBS): Definition deleted; automake will generate such
3875 things automatically.
3876 * Makefile.in: Regenerated.
3878 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3880 Simplify smob and port marking; set the mark bit in the generic
3881 marking code, and make marker routines only responsible for
3882 turning up outgoing pointers.
3883 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3884 before calling the marking function. Don't call the marking
3885 function if it's zero.
3886 * markers.c (scm_mark0): Just return #f. This function isn't
3887 necessary at all now, but it's harmless to call it. We'll leave
3888 it in so other folks' code doesn't croak at link time.
3889 (scm_markcdr): Don't call SCM_SETGC8MARK.
3890 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3891 * dynl.c (mark_dynl_obj): Same.
3892 * root.c (mark_root): Same.
3893 * srcprop.c (marksrcprops): Same.
3894 * unif.c (markra): Same.
3895 * variable.c (scm_markvar): Same.
3896 * ports.c (scm_markstream): Same.
3897 (void_port_ptob): Specify zero for our marking function.
3898 * debug.c (debugobjsmob): Same.
3899 * dynwind.c (guardsmob): Same.
3900 * filesys.c (dir_smob): Same.
3901 * fluids.c (fluid_smob): Same.
3902 * fports.c (scm_fptob, scm_pipob): Same.
3903 * mallocs.c (mallocsmob): Same.
3904 * regex-posix.c (regex_t_smob): Same.
3905 * smob.c (freecell, flob, bigob): Same.
3906 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
3907 * throw.c (jbsmob, lazy_catch_funs): Same.
3909 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3911 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
3912 scm_copy_tree on code in order not to let memoized code to leak
3913 out. Thus, scm_copy_tree needs to copy vectors as well since
3914 quasiquote can introduce evaluated code also inside vector
3917 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3919 * eval.c (scm_copy_tree): Removed ability to copy vectors.
3921 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
3922 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
3925 * unif.c: Say that ivect and uvect are of type signed and unsigned
3926 long instead of int in commentary so that it correctly describes
3929 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3931 * stime.c: Removed declaration of strptime. (It should be
3932 declared by the system headers. If it turns out that some systems
3933 don't, we'll handle that then.) (Thanks to Greg Troxel.)
3935 * stime.h: Renamed TIMEH --> STIMEH
3937 * backtrace.c (scm_display_error, scm_display_backtrace): In order
3938 to increase portability, don't use structure assignment.
3939 (Thanks to Nicolas Neuss.)
3941 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
3943 (finalize_fd_sets): Added empty statement after last case label.
3944 (Thanks to Nicolas Neuss.)
3946 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
3949 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
3951 * init.c, readline.c: OK, I won't have these readline.x bug
3952 reports anymore. We've had them since April. The current reason
3953 is a completely unintelligible failure of totoro.red-bean.com to
3954 do the test for rl_getc_function in libreadline correctly. This
3955 kludge overrides the test if we're on totoro so that the snapshot
3956 generation process can work.
3958 * readline.c: Define a strdup replacement if not existent on system.
3960 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3962 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
3963 This change makes scm_make_vector R5RS compatible. We cannot keep
3964 the third argument since people want to be able to deduce the form
3965 of the C function call only by looking at R5RS. (At the same time
3966 we have removed some unnecessary complexity!)
3968 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
3969 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
3970 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
3971 argument in call to scm_make_vector.
3973 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3975 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
3976 This macro is useful in applications.
3978 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3980 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
3981 (scm_parse_path, scm_search_path): New Scheme level procedures.
3983 * load.h (scm_internal_parse_path, scm_parse_path,
3984 scm_search_path): Declared.
3986 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3988 * filesys.c (dirname, basename): New procedures.
3990 * init.c (scm_boot_guile_1): Removed condition around
3993 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
3994 new data type (guards) for representation of C level guards and
3995 data on the wind chain.
3996 (scm_internal_dynamic_wind): New function.
3998 * dynwind.h: Declare scm_internal_dynamic_wind.
4000 * root.h (scm_root_state): Added scm_cur_loadp.
4002 * root.c (mark_root): Added comment about cur_loadp.
4004 * load.c: #include "dynwind.h";
4005 (scm_primitive_load): Use scm_inner_dynamic_wind to update
4008 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
4010 * ports.c (current-load-port): New procedure.
4012 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4014 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
4015 not a tty, return #f.
4017 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
4018 to Julian Satchell and Roland Kaufmann.)
4020 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
4021 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
4023 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
4025 * debug.h, debug.c (scm_start_stack): New function. Implements
4026 the guts of old scm_m_start_stack.
4028 * debug.c (scm_m_start_stack): Use scm_start_stack.
4030 * init.c (scm_start_stack, scm_restart_stack): Renamed to
4031 start_stack and restart_stack. (These have static scope.)
4033 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4035 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
4036 readline functions to come in release 2.3. (Thanks to Chet
4038 (handle_errors): Use the above functions.
4040 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4042 * readline.c: Improvements for readline support: Handle errors
4043 better; Implement before-read-hook.
4045 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4047 * init.c (scm_boot_guile_1), readline.c: Test for
4048 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
4049 assure that we have version >= 2.1.)
4051 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
4053 * readline.c (scm_readline): Defer interrupts while we're calling
4056 * readline.c (scm_add_history): Bugfix: Do strdup before giving
4057 away the string to add_history.
4058 (completion_function): Do completion for readline. (Thanks to
4060 (scm_filename_completion_function): New procedure: Filename
4062 (current_input_getc): New function. Use this one instead of
4063 standard getc from readline.
4065 * throw.c, throw.h (scm_handle_by_throw): New function: This
4066 handler throws errors to next handler on the dynwind chain.
4068 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
4070 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
4073 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4075 * procprop.c (scm_i_procedure_arity): New function. Returns arity
4077 (scm_procedure_properties): Modified to return arity together with
4079 (scm_procedure_property): Added the read-only property `arity'.
4080 (scm_set_procedure_property_x): It is an error to set the `arity'
4083 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
4084 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
4086 * procprop.h (scm_sym_arity): New symbol.
4088 * objects.c (scm_set_object_procedure_x): New procedure: Use this
4089 to set the dispatch procedure of an operator or entity object.
4091 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
4092 Made procedure slots read-only.
4094 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
4095 scm_tcs_cons_gloc case in zero args switch; Fixed args
4096 construction for operators in scm_tcs_cons_gloc case in two args
4099 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4101 * fluids.c: Removed use of assert.h (in order to avoid
4104 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
4106 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
4108 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
4109 change makes the evaluator safer at the cost of evaluation speed.
4110 It handles the case when the user has added a non-immediate
4111 improper end of the application form, e.g., `(+ 0 . x)'.
4112 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
4113 minimize the extra cost as much as possible. The new code is
4114 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
4115 problem with structs planted directly in the code (e.g. by a
4116 macro). This no longer causes segmentation fault. (Thanks to
4119 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
4120 arg `proc' in order to be able to throw errors; New argument
4123 * Removed extra #include "debug.h"
4125 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
4127 * scmsigs.c: Declare usleep as returning void on some systems.
4128 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
4131 * coop.c (usleep): Return void on some systems.
4133 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4135 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
4137 * coop.c: Changed return type of usleep to int.
4139 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
4140 isn't found in the OS.
4142 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
4143 isn't enabled. (Thought that I had made this change ages ago...)
4145 * iselect.c: Declare bzero if not defined by OS.
4147 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4149 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
4150 condition. (Thanks to John Tobey.)
4152 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
4153 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
4156 * __scm.h: Start the long-term project of moving to POSIX threads.
4157 Phase 1: Classification of all critical sections.
4158 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
4159 for A sections. (See comments in __scm.h for details.)
4161 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
4162 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
4164 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4166 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
4167 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
4168 (libpath.h, versiondat.h): Replaced dependency on Makefile with
4169 dependencies on $(srcdir)/Makefile.in
4170 $(top_builddir)/config.status in order to avoid circularity.
4172 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
4173 from argc if argc was 0 initially.
4175 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
4176 in generation of libpath.h.
4178 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
4180 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
4181 libguile from 2 to 3.
4183 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
4185 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
4187 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
4189 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
4190 scm_set_port_column_x, scm_port_filename,
4191 scm_set_port_filename_x): Removed optional arguments. Added
4192 proper argument checking.
4194 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
4195 stack size in machine words.
4197 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
4198 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
4199 to Ole Myren Röhne.)
4201 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
4203 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
4204 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
4206 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
4209 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
4210 procedure apply: Copy argument lists before pushing them unto the
4211 environment so that the environment won't get mutated due to
4212 manipulation of procedure arguments. This should perhaps be
4213 regarded as a temporary solution until someone finds a more
4214 efficient one. (Thanks to Maciej Stachowiak.)
4216 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
4218 * script.c (scm_compile_shell_switches): Use "guile" as default
4219 zero arg if argc is NULL.
4221 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
4223 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
4224 is zero. (Thanks to Dirk Herrmann.)
4226 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
4228 * ports.c (scm_add_to_port_table): First line is now line 0
4229 (was 1). (Interface changed according to suggestion by Per
4232 * backtrace.c (display_header): Add 1 to line and column numbers
4233 when presenting them to the user.
4235 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
4236 from debug.c --> eval.c
4238 * eval.h, eval.c (scm_eval_options_interface): New options
4240 (SCM_EVAL_STACK): New option: Size of newly created stacks,
4241 i.e. stacks for new threads.
4243 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
4245 * eval.c (unsafe_setjmp): Removed with #if 0.
4247 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
4250 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
4251 to avoid compiler warnings.
4253 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
4255 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
4257 * throw.c (handler_message): Print message on current error port
4258 instead of default error port. (Thanks to Maciej Stachowiak.)
4260 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
4262 * ports.c (scm_add_to_port_table): allocate in units of
4263 struct scm_port_table *, not struct scm_port_table.
4264 * posix.c (scm_close_pipe): remove the port from the port table
4266 Thanks to Rob Engle for both fixes.
4268 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4270 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
4271 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
4273 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4275 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
4277 * backtrace.c (display_error_body, display_backtrace_body),
4278 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
4279 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
4280 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
4281 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
4284 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
4285 don't receive the jmpbuf arg anylonger.
4286 (scm_catch): Don't accept a #f tag.
4287 (scm_throw): Check that key is a symbol.
4288 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
4290 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
4292 * async.c (async_pending): Removed declaration.
4294 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4296 * dynwind.c (scm_wind_chain): New debug function.
4298 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
4299 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
4300 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
4301 extra layer of functions around the body and handler of a thread.
4302 This extra layer makes sure that the handler is called in the
4303 dynamic context of the surround (= empty dynwind list), but under
4304 the *dynamic root* of the body. We can not use the dynamic root
4305 of the surround since that root belongs to another thread => stack
4306 is not handled correctly. It may seem ugly to use this extra
4307 layer, but the extra cost in terms of execution time is really
4308 negligible compared to the total amount of time required to create
4309 a thread, and it would reduce maintainability to duplicate the
4310 crucial and complicated steps performed by cwdr.
4312 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
4313 (SCM_ALLOW_INTS): Added thread switching code before interrupts
4314 get re-enabled. The important effect of this is that interrupts
4315 are blocked during thread switching so that thread data structures
4316 don't risk getting messed up by an unfortunate signal.
4317 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
4318 seems to do more aggressive optimization which actually move
4319 instructions around in these macros in a fatal way. Therefore:
4320 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
4321 just superstitious...)
4322 (SCM_TICK): Maybe do a context switch and take care of asyncs.
4323 This macro should be used instead of SCM_ASYNC_TICK since the
4324 latter doesn't do context switches any more.
4326 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
4327 instead of SCM_ASYNC_TICK.
4329 * coop.c, iselect.c: Since thread switches are now performed with
4330 interrupts masked, we can't use the old mechanism of delivering
4331 signals immediately when they arrive. Signals must instead be
4332 delivered when the asyncs run *after* the end of the critical
4333 section in scm_internal_select. But this also means after context
4334 switch so that the signal will be delivered to a different thread.
4335 To avoid this, I have changed the protocol of
4336 coop_wait_for_runnable_thread and friends so that they are allowed
4337 to return the original thread. So, if a signal arrives during
4338 scm_internal_select, we won't any longer be forced do a context
4339 switch, but can remain in the same thread and deliver the signal
4342 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
4343 scm_asyncs_pending and made it global.
4345 * iselect.c: Small fixes.
4347 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
4348 coop_condition_variable_init, coop_condition_variable_wait,
4349 coop_condition_variable_signal): Changed return type from `void'
4350 to `int'. This is to adhere closer to the pthreads interface.
4351 This, in turn, is part of an attempt to provide C versions of the
4352 mutex and condition variable primitives which can be part of a
4353 frontend to COOP or pthreads.
4355 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
4356 coop_condition_variable_destroy): New functions.
4358 * coop-threads.c (scm_wait_condition_variable): Use
4359 coop_condition_variable_wait_mutex.
4361 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
4362 Definitions moved to coop-defs.h.
4364 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
4365 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
4366 scm_cond_destroy): New C interface to mutecis and cond vars.
4368 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4370 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
4372 * iselect.c: Now several threads can wait on the same file
4373 descriptor. The behaviour is compatible with OS select: All
4374 threads waiting for the fd return with the same status.
4376 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4378 * coop-threads.c, threads.h (scm_spawn_thread): New function.
4379 Can spawn a thread from application C code.
4381 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4383 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
4384 gh_doubles2scm): New functions.
4386 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
4388 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
4389 commented-out version of gh_eval_str()
4391 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
4393 * socket.c (scm_bind): free soka after use.
4395 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
4397 * stime.c (tzvar): new variable.
4398 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
4399 avoid memory leaks when allocating.
4401 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
4403 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
4406 * gc.c, tags.h: Doc fixes.
4408 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4410 * eval.c (macro-eval!): Removed. This function was a design bug.
4411 It allowed memoized code to leak out to the scheme level. Most
4412 things that you could do with `macro-eval!' can be done with
4415 1997-12-20 Tim Pierce <twp@skepsis.com>
4417 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
4418 scm_fgets now depends on ftell(3) to know how many bytes were
4421 1997-12-15 Tim Pierce <twp@skepsis.com>
4423 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
4424 dealing with strings.
4426 1997-12-13 Tim Pierce <twp@skepsis.com>
4428 Make %read-line more suitable for implementing read-line efficiently.
4429 * ioext.c (scm_read_line): Strip the terminating newline from a
4430 string, and return a cons of the string and its terminator.
4432 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
4433 of the string that is read is stored in this memory location.
4434 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
4435 * genio.c, genio.h (scm_do_read_line): Update caller.
4436 * ports.h (scm_ptobfuns): Update typedef.
4437 * fports.c (scm_fptob, scm_pipob): Update struct.
4439 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4441 * filesys.c (set_element): Return file descriptor.
4442 (fill_select_type): Return the highest file descriptor.
4443 (scm_select): Tell select about the highest file descriptor. On
4444 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
4445 Therefore the extra overhead for calculating the maximum fd seems
4446 to be more than compensated. Is this correct? In any case,
4447 scm_internal_select will be much faster with this info.
4448 (scm_select, fill_select_type, set_element): Don't accept any kind
4449 of object in the file descriptor list or vector.
4451 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4453 * iselect.c (finalize_fd_sets): Bugfix.
4455 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4457 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
4458 when using scm_internal_select (since we might switch to another
4461 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
4463 * simpos.c (scm_system): always define: use sysmissing if not
4464 available. Check for HAVE_SYSTEM instead of _Windows (does
4465 Windows lack system or does it have an unusable one?).
4466 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
4467 Let the argument be optional: if not supplied, call system(NULL).
4469 * ports.c (scm_close_port): relax the type check from OPPORTP to
4470 PORTP; closing a closed port is allowed.
4472 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
4474 * fports.c (scm_fgets): Return if the last char in a chunk is
4475 newline. When fgets returns a string whose length is `size-1', it
4476 is ambiguous whether a whole line was retrieved, so we must check
4477 explicitly whether a line terminator is present.
4479 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4481 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
4482 before taking the CDR. (Thanks to Harald Meland.)
4484 * filesys.c (scm_stat): Slightly optimized.
4486 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
4488 * ports.c (scm_close_port): Make sure the port is open before
4491 * guile-snarf.in: Pass args through to gcc in a way that preserves
4492 whitespace boundaries. (Thanks to Greg Badros.)
4494 1997-12-02 Tim Pierce <twp@skepsis.com>
4496 * stacks.c (scm_frame_procedure): Reverse the logic in the return
4497 statement. (Thanks to Doug Evans for pointing this out.)
4499 1997-12-01 Tim Pierce <twp@skepsis.com>
4501 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
4503 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
4505 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
4506 errno macro expansion of this field name. (errno is a C
4507 preprocessor macro on some systems.)
4509 1997-11-29 Tim Pierce <twp@skepsis.com>
4511 * iselect.c: Doc fix.
4513 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
4515 * init.c (scm_start_stack): Removed initialization of
4516 scm_the_last_stack_var.
4518 * backtrace.h: Declare scm_the_last_stack_var.
4520 * backtrace.c: Define scm_the_last_stack_var.
4522 * root.c (mark_root): Don't mark the_last_stack_var.
4524 * root.h (scm_root_state): Removed the_last_stack_var.
4526 * throw.c: Added #include "fluids.h"
4527 (ss_handler): `the-last-stack' is now a fluid.
4529 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
4530 --> the_last_stack_fluid.
4532 * backtrace.c: Added #include "fluids.h"
4533 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
4534 (scm_backtrace): `the-last-stack' is now a fluid.
4536 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
4537 after scm_init_fluids.
4539 1997-11-28 Tim Pierce <twp@skepsis.com>
4541 * iselect.c: #ifdef USE_THREADS around thread-related includes.
4543 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
4544 DLSYM_ADDS_USCORE to decide whether to add an underscore.
4546 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4548 * iselect.c (coop_next_runnable_thread,
4549 coop_wait_for_runnable_thread): Disable interrupts so that no
4550 async is executed before a potential error_revive.
4551 (scm_internal_select): Disable interrupts during the parts of the
4552 code which manipulate the sleep queue and the file descriptors.
4554 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4556 * Makefile.am: Added iselect.c and iselect.h.
4558 * coop.c (coop_qinit): Initialize fields used by
4559 scm_internal_select.
4560 (coop_qget, coop_qget, coop_tmp_queue): Made global.
4561 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
4562 replacement in iselect.c.
4563 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
4564 coop_join): If GUILE_ISELECT enabled, use
4565 coop_wait_for_runnable_thread instead of
4566 coop_next_runnable_thread.
4567 (usleep, sleep): New replacements for system functions if
4568 GUILE_ISELECT is enabled.
4570 * coop-threads.h: Declare coop_wait_for_runnable_thread.
4572 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
4574 * filesys.c: Added #include "iselect.h". Moved FD-macros to
4575 iselect.h. Implement Scheme level `select' using
4576 scm_internal_select. (See NEWS.)
4578 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
4580 * init.c: Call scm_init_iselect.
4582 * iselect.h, iselect.c: New files. Implements
4583 scm_internal_select. (See NEWS.)
4585 1997-11-27 Tim Pierce <twp@skepsis.com>
4587 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
4588 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
4589 and scm_must_free, since ultimately the string returned will be copied
4590 by scm_makfrom0str anyway. Also, read any characters that may have
4591 been pushed onto the port with scm_ungetc.
4592 * ports.c (scm_generic_fgets): Same as for scm_fgets.
4593 * ioext.c (scm_read_line): Free string after Guilifying it.

4605 gh_repl (argc, argv).
4607 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
4609 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
4610 and to invoke scm_shell().
4611 (gh_launch_pad): took out the loading of boot-9.scm from here,
4612 since it is probably best to let the user control that. In fact,
4613 gh_repl() now invokes scm_shell() which does that.
4615 1997-11-23 Mark Galassi <rosalia@cygnus.com>
4617 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

4634 (gh_uniform_vector_ref): started implementing the uniform types in
4637 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
4639 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
4640 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
4642 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
4644 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
4645 configure.in was changed).
4647 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
4649 * Makefile.am (modinclude_HEADERS): Include readline.h here.
4650 * Makefile.in: Regenerated.
4652 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
4654 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
4655 OPORT is an `open' port, not an output port.

4663 scm_set_port_filename_x, scm_port_mode,
4664 scm_close_all_ports_except, scm_set_current_output_port,
4665 scm_set_current_error_port): Likewise
4666 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
4667 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
4669 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
4670 * backtrace.c (display_backtrace_body): Likewise
4671 * fports (scm_setvbuf): Likewise
4672 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,

4679 Minor problems with substring-related tag changes.
4680 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
4681 exactly what we want to leave in to detect substrings.
4682 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
4683 * tags.h: Fix diagrams and comments describing the S tag bit;
4684 remove vestigial remarks about the D tag bit.
4685 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
4686 * strings.c: Formatting tweaks.
4688 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
4689 variable first; then SCHEME_LOAD_PATH, with a warning message.
4690 (scm_parse_path): New function.
4691 * script.c: Doc fixes.
4693 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
4695 Readline support, from Daniel Risacher.
4696 * readline.c, readline.h: New files.
4697 * init.c: #include "readline.h".
4698 (scm_boot_guile_1): Call scm_init_readline, if we have it.
4699 * Makefile.am (libguile_la_SOURCES): Include readline.c.
4700 * Makefile.in: Regenerated.
4701 * scmconfig.h.in: Regenerated, after change to ../configure.
4703 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4705 * gh.h: gh_vector_set -> gh_vector_set_x
4707 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4709 * gh_data.c (gh_vector_set_x): changed name to make it consistent
4710 with the ! -> _x mapping when going from Scheme to C.
4712 1997-10-19 Mark Galassi <rosalia@cygnus.com>
4714 * gh.h (gh_reverse):
4722 (gh_assoc): added these gh_ functions implemented as macros.
4724 * gh_predicates.c (gh_null_p):
4725 (gh_string_equal_p): added these two missing predicates.
4727 * gh_list.c (gh_append):
4732 (gh_set_cdr_x): added these routines as I go through and try to
4733 complete the picture R4RS functions that should be mirrored in the
4736 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4738 * tags.h (scm_tc7_substring): Changed the comment and code to
4739 conform with the changes below. Folks! We have suddenly two new
4740 free tc7 codes!!! Jummy, jummy!
4742 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
4744 * Makefile.in: Rebuilt.

4770 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
4771 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
4773 Don't include "mbstrings.h".
4774 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
4775 (SCM_SYMBOL_SLOTS): Define as 4.

4800 1997-10-12 Mark Galassi <rosalia@cygnus.com>
4802 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
4804 * gh_test_c.c (c_vector_test): some improvements on the vector
4807 * gh.h (gh_vector): this used to exist but do the wrong thing.
4808 Now it (almost) does the right thing, though it takes a list
4809 instead of the individual arguments. I need to see how it could
4811 (gh_list_to_vector): added this function as a macro. Corresponds
4812 to Scheme's (list->vector ...).
4813 (gh_vector_to_list): added this function as a macro. Corresponds
4814 to Scheme's (vector->list ...).
4816 * gh_data.c (gh_vector_ref): renamed from gh_vref to
4817 gh_vector_ref, so that it resembles the Scheme routines more.
4818 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
4819 resembles the Scheme routines more.
4820 (gh_make_vector): this used to be (stupidly) called gh_vector().
4821 This is the right name, since it does the same thing as the Scheme
4822 (make-vector ...) procedure.
4824 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
4826 * ports.h: #include "libguile/print.h"

4829 Some indentation fixes.
4831 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
4832 longer a user field; New field: class_flags.
4834 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
4836 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
4838 * gh_data.c (gh_bool2scm): new function which replaces
4839 gh_int2scmb(), which is now tagged as obsolete.
4841 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
4843 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
4844 macros should by convention not test for NIMPness.)
4845 (SCM_COERCE_OPORT): Adjust indentation.
4847 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
4848 SCM_NIMP test before SCM_PRINT_STATE_P.
4850 * struct.c, struct.h, gc.c: Renamed:
4851 scm_struct_i_layout --> scm_vtable_index_layout
4852 scm_struct_i_vcell --> scm_vtable_index_vcell

4854 scm_struct_i_printer --> scm_vtable_index_printer
4855 scm_struct_i_vtable_offset --> scm_vtable_offset_user
4857 * struct.c (scm_print_struct): Use new printer slot; Default
4858 printing: Also output hex code of vtable so that type identity
4859 will be indicated as well.
4860 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
4861 Removed struct_printer_var; Removed struct-vtable-offset;
4862 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
4863 vtable-offset-user): New constants.
4865 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
4866 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.

4868 the type represented by this vtable.
4870 * print.c (scm_iprin1): Don't print arguments of macro
4871 transformers. (They are always: exp env.); Bugfix: Unmemoize
4872 transformer source with correct environment.
4874 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
4876 Streamlining of call-with-dynamic-root:

4879 there is now only one catch.
4880 (cwdr_outer_body): Removed.
4881 (cwdr_handler): New function.
4882 (scm_internal_cwdr): New function to perform the function of cwdr
4883 but take args that are more useful to C code. Also, the handler
4884 is now invoked *outside* of the new dynamic root, like the docs
4885 say. We no longer have to catch absolutely all errors, the caller
4886 is responsible for using a handler that does not throw, if he
4888 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4889 * root.h (scm_internal_cwdr): New prototype.
4891 Even more but risky streamlining:
4893 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4894 allocation of the jumpbuf of a root continuation. The changes
4895 below are controlled by it. They are now deactivated.
4896 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4897 the JMPBUF of the scm_rootcont to NULL before returning.
4899 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
4900 when they are non-NULL.
4901 (scm_gc_mark): Likewise, mark only when non-NULL.
4903 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
4904 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
4906 * gc.c (scm_done_malloc): New function.
4907 gc.h (scm_done_malloc): New prototype.
4909 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.

4916 a certain value is acceptable as a port argument.
4917 (scm_print_state_vtable): New variable.
4918 (scm_free_print_state): Set `revealed' field to false.
4919 (scm_iprin1): Call user supplied closure printer with
4920 scm_printer_apply. Print in the traditional way when there isn't
4921 one or when it returns #f.
4922 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
4923 Accept a port/print-state pair in addition to just a port.
4924 (scm_prin1): Don't return the print_state to the pool when it has
4926 (scm_printer_apply): Set `revealed' field of print_state to true.
4927 (scm_init_print): Set scm_print_state_vtable.
4928 (print_state_fluid, print_state_fluid_num): Removed.
4930 * throw.h (scm_handle_by_proc_catching_all): New prototype
4931 throw.c (scm_handle_by_proc_catching_all): New function
4933 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
4935 * Makefile.in: Regenerated with automake 1.2c.
4937 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
4939 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
4940 was looping endlessly.
4942 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
4944 * strports.c (scm_eval_string): Don't close the port.
4946 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
4947 former returns a nice normal integer. (Thanks to Daniel
4950 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
4952 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
4953 makefile variable as a build parameter called LIBS. The
4954 build-guile program will use this, for the time being.
4955 * Makefile.in: Regenerated.
4957 Thanks to Shiro Kawai:
4958 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
4959 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
4962 * Makefile.in: Regenerated with automake 1.2a.
4964 * script.c (scm_compile_shell_switches): If we hit the -c or --
4965 arguments, don't set the car of (command-line) to scm_usage_name,
4966 the prettified name of the guile executable; give it the full
4967 path, the way shells usually handle $0.
4969 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4971 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
4972 Scheme-level name `array-map' and renamed `serial-array-map' to
4973 `serial-array-map!'.
4975 * backtrace.c: Introduced exception handlers which now enclose
4976 `display-error' and `display-backtrace' so that error reporting
4977 won't get into infinite loops if an error occurs during displaying
4978 of the error. This can very easily happen with user supplied
4979 print call-back routines.
4981 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4983 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
4984 the names `serial-array-map' and `array-map' should be removed.)
4986 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
4988 * init.c (scm_boot_guile_1): Added scm_init_objects ().
4989 Added #include "objects.h"
4991 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
4992 Add #include "feature.h".
4994 * Makefile.am (libguile_la_SOURCES): Added objects.c.
4995 (modinclude_HEADERS): Added objects.h.
4997 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
4998 This test is needed at many places in the code and should be
4999 abstracted. (Motivated by the need of this test in libguiletk.)
5001 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
5002 (scm_eval_string), load.c (scm_primitive_load,
5003 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
5004 Use SCM_EOF_OBJECT_P.
5006 * eval.c (scm_init_eval): Add feature `delay'.
5008 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5010 * scmhob.h: Removed.
5012 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5014 * list.h (SCM_LISTn): New macros. Make list creation in C code
5015 prettier. The idea comes from STk.
5017 * sequences.h, sequences.c, append.h, append.c: Removed. These
5018 files implemented non-R4RS operations which would encourage
5019 non-portable programming style and less easy-to-read code.
5021 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
5024 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
5025 sequences.h, #include append.h.
5027 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and

5032 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
5034 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
5036 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5038 * eval.c: Added #include "objects.h"
5040 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
5043 * smob.c (scm_smob_prehistory): Create two objectsmobs with
5044 adjacent smob numbers.
5046 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5048 * procprop.h: Added declaration of scm_i_inner_name.
5050 * gsubr.c: New global symbol scm_i_inner_name.
5052 * debug.c (scm_procedure_name): Try procedure property
5053 `inner-name' if `name' fails.
5055 * print.c (scm_iprin1): Use scm_macro_name.
5057 * eval.c (scm_m_define): Give names to macros as well; Only the
5058 first top-level definition gives a procedure/macro a name.
5059 Otherwise confusing names can turn up in backtraces.
5060 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
5061 `name'; Give names to macros as well.
5063 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
5064 (scm_macro_transformer): Use SCM_CLOSUREP instead of
5067 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5069 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
5071 (prinmacro): Removed. The code has been moved/merged into print.c
5072 in order to decrease code redundancy. We want macros to print in
5073 a way equivalent to procedures, and it would be silly to duplicate
5074 the required code. (We don't want to maintain two places.)
5075 (macrosmob): Print field is now a NULL pointer.
5077 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
5078 scm_macro_transformer): New prototypes.
5079 (scm_tc16_macro): Declared.
5081 * print.c (scm_iprin1): Added code for printing of macros. Macros
5082 are now printed in a way equivalent to procedures.
5084 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
5086 * procs.h (scm_closure_p): Added declaration.
5088 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5090 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
5091 Shouldn't pass "heap" as the subr name.
5093 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
5095 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
5096 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
5097 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
5098 gh_equal_p): Use SCM_NFALSEP, instead of testing against
5099 SCM_BOOL_T. Any non-false value is true.
5101 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5103 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
5104 scm_gensym): Added prototypes.
5106 * symbols.c (scm_gensym): New function. This will speed up
5107 certain types of applications (such as macro systems) which
5108 generate lots of symbols.
5110 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5112 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
5114 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
5116 * unif.c (scm_shap2ra): tighten the checking of the array dimension
5117 specifier, since (2) or (2 . 3) would cause SEGV.
5118 (scm_transpose_array): more argument checking fixes.
5120 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
5122 * Makefile.in: Regenerated.
5124 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
5126 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
5128 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5130 * error.c, error.h (scm_error_callback): Removed (see NEWS).
5132 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
5134 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
5135 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
5138 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
5139 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
5140 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
5141 scm_array_p, scm_array_rank, scm_array_dimensions,
5142 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
5143 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
5144 scm_array_prototype): Added case scm_tc7_wvect.
5146 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
5148 * errno.h: prototype for scm_strerror.
5149 * error.c (scm_strerror): new procedure.
5151 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5153 * list.c (scm_list_append_x): Allow non-pair as last argument.
5154 This is consistent with the R4RS append and is probably the
5155 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
5157 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
5159 * stime.h: prototype for scm_times.
5160 * stime.c (scm_times): new procedure.
5161 * ioext.c (scm_fseek): if the first argument is a file descriptor
5163 (scm_ftell): if the first argument is a file descriptor call lseek
5165 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
5166 * filesys.c (scm_chmod): if the first argument is a file descriptor,
5168 (scm_chown): if the first argument is a port or file descriptor,
5170 (scm_truncate_file): new procedure.
5171 Add DEFER/ALLOW INTS to a few other procedures.
5172 (scm_fsync): new procedure.
5173 (scm_open_fdes): new procedure.
5174 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
5176 (scm_fcntl): the first argument can now be a file descriptor. The
5177 third argument is now optional.
5179 * posix.c (scm_execl, scm_execlp): make the filename argument
5180 compulsory, since omitting it causes SEGV.
5181 (scm_sync): return unspecified instead of #f.
5182 (scm_execle): new procedure.
5183 (environ_list_to_c): new procedure.
5184 (scm_environ): use environ_list_to_c. disable interrupts.
5185 (scm_convert_exec_args): take pos and subr arguments and
5186 improve error checking.
5188 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5190 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
5191 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
5192 argument to SCM_ASSERT. Furthermore, the name of the function
5193 should be passed as first argument when signalling
5194 SCM_WNA. (Thanks to Thomas Morgan)
5196 * gsubr.c (scm_gsubr_apply): From Radey Shouman
5197 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
5198 dispatches on the number of actual args has a default case
5199 reporting an internal error. This is a vestige from a version
5200 that mallocated a SCM vector to hold the arguments. In the
5201 current version this check is too late: if it ever happens we will
5202 have already overstepped the bounds of the array.
5204 Also, the patch [...] adds a check for too many actual arguments."
5206 mdj: Removed check for "internal programming error".
5208 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5210 * gh_io.c (gh_write): New function.
5212 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
5213 throw.c (scm_internal_stack_catch): New sibling to the other catch
5214 functions. Code moved from gh_eval.c.
5215 throw.h: Added header.
5216 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
5217 scm_internal_stack_catch.
5219 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5221 * ioext.h: fix up prototypes.
5222 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
5223 Scheme name is now dup->fdes.
5224 (scm_dup_to_fdes): make the second argument optional and
5225 fold in the functionality of scm_primitive_dup.
5226 (scm_primitive_dup): deleted.
5228 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
5230 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
5231 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
5232 ultrix are defined. Use setvbuf instead of setbuf.
5233 (scm_setvbuf): new procedure.
5234 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
5235 (scm_setfileno): moved from ioext.c.
5236 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
5237 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.

5246 * print.c (scm_iprin1): Enter printed structures into the print
5247 state as nested data while they are printed.
5248 (print_state_fluid, print_state_fluid_num): New variables.
5249 (scm_init_print): Initialize them.
5250 (scm_iprin): If print_state_fluid carries a print_state, use that
5251 instead of creating a new one.
5252 (scm_printer_apply, apply_stub, struct apply_data): New
5253 definitions to help with calling printer functions written in
5255 * print.h (scm_printer_apply): New prototype.

5268 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
5269 SCM_ASSERT: arg comes before pos.
5271 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5273 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
5274 to a list of length zero correctly.
5276 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5278 Supply an `fgets' method for port objects to do fast line i/o.

5292 * ioext.h: removed scm_duplicate_port prototype.
5294 * ioext.c (scm_primitive_dup2): return the new file descriptor
5295 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
5297 (scm_fdopen): bug fix: don't try to make port unbuffered until its
5298 stream has been set.
5299 (scm_duplicate_port): deleted, there's now an implementation in
5301 (scm_primitive_dup2): do nothing if newfd == oldfd.
5303 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
5305 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the

5311 * fluids.c (next_fluid_num): don't do
5312 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
5314 * ports.h: prototypes too.
5315 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
5317 * fports.h: prototype too.
5318 * fports.c (scm_evict_ports): moved from ioext.c.
5320 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5322 * ports.c (scm_close_port): return a boolean instead of unspecified.
5323 throw an error if an error other than EBADF occurs.
5325 * filesys.h: scm_close prototype.
5326 * filesys.c (scm_close): new procedure, can close file descriptors
5327 and ports (scsh compatible).
5329 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
5332 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
5334 * fluids.c, fluid.h: New files.
5335 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
5336 (modinclude_HEADERS): Added "fluids.h"

5345 (scm_make_root): Call scm_copy_fluids to make fluid bindings
5346 unique for the new root when it has a parent.
5348 * smob.h: Include "libguile/print.h" to make scm_print_state
5351 * dynl.c (free_dynl_obj): New function to free the dynamic object
5352 data. (dynl_smob): Use it.
5353 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
5354 the dynamic object data below the linking of the object to avoid
5355 memory leak when the linking code throws an error. Now the code
5356 leaks a whole dynamically linked library when must_malloc throws,
5357 but that should be much less likely.
5359 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
5361 Changes to compile under gnu-win32, from Marcus Daniels:

5363 (scm_localtime): Change SCM_EOF to SCM_EOL.
5364 (scm_mktime): Likewise.

5377 (scm_setpwent): For setpwent.
5378 (scm_setegid): For setegid.
5379 * net_db.c (scm_inet_netof): Don't include unless support

5395 scm_misc_error, not SCM_EOF.
5397 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
5398 arguments for formatting the error message, not SCM_BOOL_F. I
5399 think this is left over from the (eq? '() #f) days.
5401 * read.c (recsexpr): Give this a dummy definition if
5402 DEBUG_EXTENSIONS isn't #defined.
5404 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
5406 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
5409 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>

5416 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
5417 alloca.lo will be included in @LIBLOBJS@. Something better than
5418 this should be possible.
5419 * Makefile.in: Regenerated.
5421 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
5423 * simpos.h: prototype for scm_primitive_exit.
5424 * simpos.c (scm_primitive_exit): new procedure, terminates the
5425 process without unwinding the stack.
5427 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
5429 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
5430 argument and logior its components together, so the user doesn't
5431 have to do this explicitly. Also, if regexp/basic is supplied, then
5432 turn off REG_EXTENDED.
5433 (scm_init_regex_posix): New regexp/basic symbol.
5434 (REG_BASIC): #define this if it is not already present.

5450 * Makefile.in: Regenerated.
5452 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
5453 flag; I don't think we support it.
5454 (scm_make_regexp): Make sure the user doesn't pass the
5457 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
5459 (scm_init_regex_posix): Define constants for the REG_mumble flags;

5467 Makefile directory variables. Print a message, but don't print
5469 (versiondat.h): Print a message, but don't print all the commands.
5470 * load.c: #include "alist.h".
5471 (init_build_info): New function.
5472 (scm_init_load): Call it.
5473 * Makefile.in: Regenerated.
5475 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
5477 * root.c: Establish a reliable catch-all handler for the new root.
5478 After all the Scheme handler function might signal an error too,
5479 and we don't want to lose that.
5480 (cwdr_inner_body): Renamed from cwdr_body.
5481 (cwdr_outer_body): New function, to establish the user's handler,
5482 and pass control to cwdr_inner_body.
5483 (cwdr): Establish the reliable catch-all handler here, and pass
5484 control to cwdr_outer_body.
5485 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
5486 the user's handler through to cwdr_outer_body.

5493 across this. Only works on GCC. Otherwise, we hope for the best.
5494 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
5495 the feeling that real thread systems will not need this...
5497 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
5499 Try to detect when people are using one version of libguile and a
5500 different version of ice-9. People have been skewing things and
5501 sending in bug reports.

5507 * scmconfig.h.in, Makefile.in: Regenerated.
5508 * Makefile.in: Regenerated.
5510 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
5511 primitive definitions under their Scheme names.
5513 * Makefile.am (libguile_la_LDFLAGS): Update library version to
5514 1:2. Helps avoid confusion between installed and uninstalled libs.
5516 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
5519 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
5520 backslash from definition; this should be used like: GDB_INTERFACE;
5522 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5524 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
5525 new port unbuffered until its stream has been set.
5527 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
5529 * ports.h: new prototype.
5530 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
5532 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
5534 Make things compile neatly under Sun's C compiler.
5535 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
5536 * extchrs.c (xmbtowc): Make the second arg a normal char, not
5537 unsigned, because that's what the ANSI function takes.
5538 * extchrs.h (xmbtowc): Corresponding change to prototype.
5539 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
5541 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
5542 argument plain char *.
5543 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
5545 * tag.c (scm_tag): Remove unreachable statement.
5546 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
5547 top of the word, it should be unsigned.
5549 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
5550 is defined, to avoid warnings; it's only used in the
5551 conflict-checking code. Which might go away anyway.
5552 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
5553 conditionals; put the label definition in an #if too, to stifle
5556 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
5557 ChangeLog-threads in the distribution.
5558 * Makefile.in: Regenerated.
5560 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5562 * guile-snarf.in: Changed regexp to support CPPs that insert
5563 whitespace between lexical tokens (which munges the `%%%' snarf
5566 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
5568 * load.c (scm_init_load_path): Append $(datadir)/guile to
5569 %load-path, so modules do not have to be installed in Guile's
5570 current version directory.
5572 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
5574 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
5575 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
5576 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
5577 call the sysdep functions with deferred ints.
5578 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
5579 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
5580 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
5583 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
5586 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
5588 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
5590 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
5592 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
5595 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
5597 * eval.c (scm_lookupcar1): New procedure to cope with a race
5598 condition during lookup (when using threads).
5599 (scm_lookupcar): Implement in terms of scm_lookupcar1.
5600 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
5603 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
5605 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
5606 supplied. (Change from Tim Pierce.)
5608 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
5610 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
5611 23:47:01 1997" changelog: Slots are now initialized with `#f' by
5612 default and not `()'. `#f' is the canonical non-value in Scheme,
5615 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5617 * struct.c (struct_printer): New variable that holds a handle on
5618 the Scheme variable *struct-printer*. This variable can be set by
5619 Scheme code to override the printing of structures.
5620 (scm_print_struct): If struct_printer is set, call it. If it is
5621 not set, or returns #f, print the structure in the old fashion.
5622 Include "eval.h" for scm_apply.
5624 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
5626 * struct.c (scm_struct_ref, scm_struct_set_x): Use
5627 scm_struct_i_n_words to get the number of fields, not
5628 -scm_struct_n_extra_words.
5630 On the route to fancier struct printing:
5631 * struct.c (scm_print_struct): New function to print a structure.
5632 Include "genio.h" to support it. This function doesn't do
5633 anything interesting right now, but I think it should be here
5635 * struct.h: Include "print.h" and add prototype for
5637 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
5638 print structures ourself.
5640 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5642 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
5643 before applying the handler in case it doesn't return.
5645 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
5647 * scmsigs.h, async.h: updated.
5649 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
5652 * posix.c (scm_uname): interpret only negative values as an error.
5653 Solaris normally returns a positive value.
5655 * script.c (scm_compile_shell_switches): if we are not going into
5656 an interactive repl, set scm_mask_ints to zero so that asyncs can
5659 * simpos.c (scm_system): don't ignore/unignore signals around
5662 * posix.c (scm_open_pipe): don't ignore/unignore signals around
5665 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
5666 done in boot-9.scm instead.
5668 * scmsigs.c, async.c: Major rewriting of signal handling code.
5669 (scm_sigaction): new procedure.
5670 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
5672 (scm_raise): return unspecified, throw error on failure.
5674 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5676 * regex-posix.c (scm_init_regex_posix): Register the "regex"
5677 feature, to help boot-9.scm decide whether to import the regex
5680 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5682 * eval.c: Include scmconfig.h at the beginning of the file so that
5683 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
5686 * regex-posix.c: #include "_scm.h" before conditionally #including
5687 <regex.h>; the former defines HAVE_REGCOMP.
5689 * regex-posix.c: #include <regex.h> conditionally, so the file is
5690 CPP'able (for dependency scanning) even on systems that don't have
5693 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5695 Add new R4RS-compliant syntax for keywords.
5696 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
5697 regardless of the setting of the `keywords' read option.
5698 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
5699 can be re-read no matter what the setting of the `keywords' read
5702 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
5704 Add support for POSIX regular expressions.
5706 * regex-posix.c, regex-posix.h: New files. (Some code
5707 is taken liberally from rx/rgx.c in the old Guile dist.)
5709 * init.c: Include regex-posix.h.
5710 (scm_boot_guile_1): Call scm_init_regex_posix.
5712 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
5713 Add regex-posix.[ch] sources.
5714 * Makefile.in: Regenerated.
5716 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
5717 to do this automatically? It didn't for me, bleh.)
5719 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
5721 * fports.c (print_pipe_port): New function.
5722 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
5723 latter doesn't even take the right arguments.
5725 * Makefile.am: Increment shared lib revision number. I think
5726 sometimes the uninstalled Guile finds the installed shared lib;
5727 Gord says doing this might help. As things turned out, I can't
5728 say whether it does.
5729 * Makefile.in: Regenerated.
5731 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
5732 passing it as the closure argument to scm_boot_guile. (Bill
5735 * ports.c (print_void_port, putc_void_port, puts_void_port,
5736 write_void_port, flush_void_port, getc_void_port, close_void_port,
5737 noop0): Use ANSI prototypes instead of K&R declarations, so the
5738 initialization of void_port_ptob gets aggressively type-checked.
5739 Fix arguments of print_void_port and write_void_port. (Bill

5773 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
5775 * script.c (scm_find_executable): Use prototype-style definition
5776 here; apparently it's not quite right to have const in a prototype
5777 and then use a K&R declaration. I wonder if stuff like this will
5778 go away if we compile with -Wrequire-prototypes, or whatever that
5779 is... (Bernard URBAN)
5781 * scmhob.h: New text from Bernard URBAN.
5783 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5785 * script.c: Don't #define const on hpux. Configure takes care of
5786 this. (Thanks to Larry Schwimmer.)
5788 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
5789 decide whether to #include <unistd.h>, instead of listing a bunch
5790 of systems. Don't #include stdio twice. Removed dyked-out
5791 definition of scm_find_impl_file.
5793 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5795 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
5796 library version info to 1:0.
5797 * Makefile.in: Regenerated.
5799 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

5803 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
5804 throw.c: Update copyright years; these files have been worked on
5805 significantly in 1997, but only had copyright years for 1996.
5806 Also, change name of copyright holder on some from Mikael
5807 Djurfeldt to Free Software Foundation; he has signed papers
5808 assigning the changes to the FSF.
5810 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
5811 reason not to give the user the option.
5813 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5814 Return #f on end-of-file when scanning table (i.e. when called
5815 with no arguments). Try to catch errors, when we can.
5816 * posix.c (scm_getgrgid, scm_getpwuid): Same.
5818 * script.h (scm_shell_usage, scm_compile_shell_switches): New
5819 external declarations. These are useful.
5821 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
5823 * posix.c: don't include <sys/select.h> or define macros for
5824 select, since they were not used in this file.
5826 * filesys.c (scm_select): make the fifth parameter microseconds,
5827 not milliseconds. let the fourth parameter be either a real value
5828 or an integer or #f. The first, second and third arguments can
5829 now be vectors: the type of the corresponding return set will be
5831 (set_element, get_element): new static procedures.
5833 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
5835 * strports.c (scm_eval_string): New function.
5836 (scm_eval_0str): Trivially re-implemented in terms of
5838 * strports.h (scm_eval_string): New extern decl.
5840 * net_db.c (h_errno): Add extern decl for this.
5842 * fports.c (local_pclose): New function.
5843 (scm_pipob): Use it in the initializer here.
5846 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
5847 Use a meaningful error message when signalling an error. For
5848 this, scm_gethost must check h_errno rather than errno.
5850 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
5852 * Makefile.in: Regenerated, using automake-1.1p.
5854 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5856 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
5857 not SCM_UNSPECIFIED.
5859 * script.c (scm_compile_shell_switches): don't append (quit) if
5861 (scm_shell): call scm_exit_status and exit on the result of the
5864 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
5866 Ensure that shared substrings are handled properly when passed to
5867 a system call or other foreign function. Many thanks to Tim
5869 * symbols.h (SCM_COERCE_SUBSTR): new macro.
5870 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
5871 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
5872 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

5887 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5889 * error.c (scm_error): Add newline to error message.
5891 * init.c (scm_init_standard_ports): Doc fix.
5893 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5895 * dynl-shl.c: Completely replaced with new code from Bernard
5898 * script.c (scm_ice_9_already_loaded): New variable.
5899 (scm_compile_shell_switches): Use it.
5901 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5903 * filesys.c (scm_input_waiting_p): add missing third argument to

5907 calling gmtime in case they share a buffer.
5908 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
5911 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5913 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
5915 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
5917 * Makefile.am (check-local): New target, which causes 'make check'
5918 to run gh_test_c and gh_test_repl, with some trivial input.
5919 * Makefile.in: Rgnrtd.
5921 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
5923 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
5926 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
5928 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
5929 sure how this was supposed to work.
5930 (scm_async_click): don't send SCM_TICK_SIGNAL.
5931 (scm_init_async): don't initialize %tick-thunk.
5933 * the following change doesn't affect the Scheme interface:
5934 gc-thunk is called at the end of garbage collection. however it's
5935 no longer implemented by pretending it's a signal.
5937 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
5938 system async corresponding to scm_gc_thunk.
5939 * async.h: declare scm_gc_async.
5940 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
5941 gc-thunk directly, instead of going through a signal handler.
5942 (scm_gc_async): new variable, points to the GC system-async.
5943 (scm_init_async): save the GC async as scm_gc_async instead
5944 of using system_signal_asyncs.
5945 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
5947 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>

5950 Don't screw up if we're interrupted.
5951 * Makefile.in: Regeneradet.
5953 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
5955 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
5957 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
5958 we're not using AM_INIT_GUILE_MODULE any more.
5959 * Makefile.in: Reneregated.
5961 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>

5969 * Makefile.in: Regenerated, like a surry without a fringe on top.
5971 Changes for reduced Guile distribution: one configure script,
5973 * configure.in, configure: Removed.
5974 * acconfig.h, acinclude.m4: Moved to parent directory, where the
5975 real configure script lives.
5976 * Makefile.in, scmconfig.h.in: Regenerated.
5978 * init.c: #include "script.h", to get prototype for script.c's
5981 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
5983 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
5984 scm_must_malloc, not raw malloc.
5986 * script.c (scm_compile_shell_switches): Dyke out debugging output
5989 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5991 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
5993 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
5994 system has them. Hope this is safe. Previously
5995 sys/timeb.h was included if HAVE_FTIME was defined or if
5996 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
5997 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
5999 * ioext.c (scm_setfileno): add missing third argument to
6000 scm_misc_error call.
6002 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
6004 * eq.c (scm_equal_p): Correctly compare strings of different
6005 varieties. (Thanks to Tim Pierce.)
6007 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
6009 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
6010 #! block comment must occur on a line all by itself.
6012 Move most of the guts of shell command processing into libguile,
6013 so guile.c can be very small (and eventuallly auto-generated. (I
6014 mean, generated mechanically, not self-generated. Hmm.))
6015 * guile.c, script.c, script.h: New source files.
6016 * init.c (scm_boot_guile_1): Call scm_init_script.
6017 * libguile.h: #include "script.h".
6018 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
6019 targets, for new executable.
6020 (libguile_la_SOURCES): Mention script.c.
6021 (modinclude_HEADERS): Add script.h.
6022 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
6023 not dynamic linking is enabled. This is because we're generating
6024 executables now. Move CY_AC_WITH_THREADS call after those, so the
6025 values of cy_cv_threads_libs captures the libs chosen above.
6026 * Makefile.in, configure, aclocal.m4: Regenerated.
6028 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
6029 We don't maintain this interface any more, and it just confuses
6032 * alloca.c: #include <scmconfig.h>, not <config.h>.
6033 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
6034 it'll get included in disties.
6036 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
6038 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
6039 be distributed, because they confuse people.
6040 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
6042 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
6044 * configure.in: check for presence of gethostent (not present on
6045 OpenBSD by default).
6046 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
6047 * configure, scmconfig.h.in: Regenerated.
6049 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
6051 * backtrace.c (scm_backtrace): Split message string across
6052 newlines properly. GCC is more tolerant of this than other
6055 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
6057 Merge threads directory into libguile.
6058 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
6059 threads.h: New source files.
6060 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
6061 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
6063 (modinclude_HEADERS): Add threads.h, coop-defs.h.
6064 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
6065 coop-threads.c.cygnus, coop-threads.h.cygnus.
6066 * configure.in: If we're using threads, include threads.o in
6068 * _scm.h, libguile.h: threads.h lives in this directory now.
6069 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
6070 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
6071 currently used, but brought along for information's sake.
6072 * ChangeLog-threads: log from old 'threads' directory.
6073 * Makefile.in, configure: Rebuilt.
6075 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
6077 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
6080 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
6082 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
6084 Merge GH interface library into libguile.
6085 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
6086 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
6087 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
6088 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
6090 (EXTRA_libguile_la_SOURCES): ... here.
6091 (pkginclude_HEADERS): Add variable, to get gh.h installed.
6092 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
6093 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
6094 New variables, describing how to build the gh test programs.
6095 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
6096 build the test programs, and we probably should have been linking
6097 libguile.la against them all along, to support AIX shared libs.
6098 Add cflags for threads to CFLAGS; add libs for threads to new
6099 variable THREAD_LIBS, used in Makefile.am.
6100 * ChangeLog-gh: log from old `gh' subdirectory.
6101 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
6103 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
6105 * acconfig.h: Undo change of Apr 9; including the definition of
6106 PACKAGE in the guile headers conflicts with applications' own
6108 * scmconfig.h.in: Regenerated.
6110 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

6114 * filesys.h: Added prototype.
6116 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
6117 when PROC is receiving no arguments.
6119 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
6121 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
6122 have S_IFSOCK. This is the case under Ultrix.
6124 * posix.c (scm_status_exit_val, scm_status_exit_val,
6125 scm_status_term_sig, scm_status_stop_sig): Modified to work with
6126 Ultrix versions of WIFSTOPPED, etc., which assume that their
6127 arguments are lvalues (hmm).
6129 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
6131 * eval.c: Doc fixes.
6133 * throw.c: Doc fixes; rearranged.
6135 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
6137 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
6139 * acconfig.h: Added entry for PACKAGE.
6140 * scmconfig.h.in: Regenerated.
6142 Changes to work with automake-1.1n, which has better libtool support.
6143 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
6144 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
6146 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
6148 * Makefile.in: Rebuild.
6150 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6152 * stime.c (scm_mktime): take an optional zone argument.
6153 (scm_localtime): check putenv return value.
6154 (scm_strftime, scm_strptime): moved from posix.c. move #include
6156 stime.h, posix.h: update prototypes.
6157 (bdtime2c, setzone, restorezone): new static procedures.
6158 (scm_mktime, scm_strftime): use them.
6159 (scm_strftime): don't call mktime before strftime. Use
6160 filltime for return value.
6161 (filltime): convert NULL zname to #f.
6162 (scm_strptime): return a count of characters consumed, not
6163 the remaining string.
6165 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6167 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
6168 (scm_mktime): likewise.
6170 Uncomment localtime and mktime.
6172 * configure.in: add AC_STRUCT_TIMEZONE.
6174 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
6176 * stime.c (scm_init_stime): don't define ticks/sec.
6177 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
6178 return value problem and is still portable.)
6180 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6182 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
6183 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
6184 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
6185 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
6186 cpp_err_symbols.c): Corresponding changes.
6187 * Makefile.in: Regenerated.
6189 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6191 * posix.c (scm_putenv): don't check HAVE_PUTENV.
6192 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
6193 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
6194 * putenv.c: new file, from sh-utils 1.12.
6196 * posix.c (scm_environ): use malloc in place of scm_must_malloc
6197 since allocation isn't for Scheme objects.
6198 (scm_putenv): copy strings before placing in the environment.
6200 * stime.c (scm_current_time): throw an error if time returns -1,
6201 instead of returning #f.
6202 (scm_get_internal_real_time, scm_get_internal_real_time): use
6203 scm_long2num for return value instead of SCM_MAKINUM.
6205 * stime.h: prototypes updated.
6207 * stime.c (scm_time_in_msec): apparently unused, deleted.
6209 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
6211 * configure.in: check for gettimeofday.
6213 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
6214 which may be more usefully portable than a gettimeofday interface.
6216 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
6218 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
6220 * Makefile.in: Regenerated.
6222 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6224 * stime.c (filltime): recovered static procedure.
6225 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
6228 * posix.h: add prototype for scm_close_pipe, remove prototypes for
6229 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
6231 * posix.c (scm_mknod): split the mode argument into type and perms
6232 arguments, like the extra fields returned by stat.
6234 * fports.c (scm_pipob): set the close, free and print procedures.
6235 (scm_close_pipe): new procedure.
6237 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
6238 define them in boot-9.scm
6240 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6242 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
6243 wan't defined. Don't include fd.h.
6245 * Previously fd.h was regenerated whenever configure was run,
6246 forcing a couple of files to be recompiled.
6248 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
6249 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
6250 Check for _fileno as well as _file.
6252 * ioext.c: don't fd.h.
6253 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
6256 * Change the stratigy for getting information about errno
6257 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
6258 generating lists of symbols during the build process, which will
6259 not always work, include comprehensive lists in the distribution.
6260 To help keep the lists up to date, the "check_signals" and
6261 "check_errnos" make targets can be used.
6263 * configure.in: don't check for a command to extract errno codes.
6264 * Makefile.am: update file lists, remove errnos.list and errnos.c
6265 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
6266 check_errnos targets.
6267 (CLEANFILES): remove errnos.c and errnos.list, add
6268 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
6269 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
6270 * errnos.default: deleted.
6271 * cpp_signal.c: new file.
6272 * cpp_errno.c: renamed from errnos_get.c.
6273 * cpp_err_symbols, cpp_sig_symbols: new files.
6274 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
6275 * error.c (scm_init_error): #include cpp_err_symbols instead of
6277 * posix.c (scm_init_posix): don't intern signal symbols. #include
6280 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
6282 * strop.c (scm_i_index): allow the lower bound to be equal to the
6283 length of the string, so a null string doesn't always give an error.
6285 * posix.h: new prototypes.
6286 * posix.c (scm_status_exit_val, scm_status_term_sig,
6287 scm_status_stop_sig): new functions, as in scsh. They break down
6288 process status values as returned by waitpid.
6290 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
6292 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
6293 configure doesn't know about it.
6295 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6297 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
6299 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
6300 which defines C variables with global linkage.
6302 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6304 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
6307 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
6309 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
6310 has time to check why this doesn't work well with continuations.
6312 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
6314 * Fix shell syntax error; some shells won't tolerate
6315 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
6317 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
6319 * posix.c (scm_uname): throw an error if uname fails instead
6322 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
6324 * error.c (err_head, scm_errno, scm_perror): obsolete procedures

6331 * acconfig.h: Removed PACKAGE.
6333 * scmconfig.h.in: Regenerated.
6335 * snarf.h: g++ says it's non-portable not to specify the first
6336 argument in a varargs declaration. I introduced the first
6337 argument by using preprocessor conditionals.
6339 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
6341 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
6342 (scm_freopen): use RO string macros for filename and modes.

6356 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
6359 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,

6361 support for byte vectors.
6363 * print.c (scm_iprin1): Limit number of vector elements printed
6364 according to pstate->length.
6366 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>

6371 * error.h: prototype for scm_error_scm.
6373 * error.c (scm_error_scm): new procedure, reimplements scm-error
6374 in C and uses scm_error.
6376 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6378 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
6379 pointer to the Scheme variable read-hash-procedures and intern it
6380 in scm_init_read. Modify scm_read_hash_extend and
6381 scm_get_hash_procedure to use the pointer.
6383 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6385 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
6386 (SCM_KEYWORD_STYLE): defined.
6388 * read.c (scm_read_opts): add a keywords option. This isn't a
6389 boolean option, in case someone wants to add support for DSSSL
6391 Setup scm_keyword_prefix symbol.
6392 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
6394 I've left keyword support disabled by default, since it doesn't
6395 seem to break the module system and it gives R4RS standard behaviour.
6396 It can be reactivated with (read-set! keywords 'prefix).
6398 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6400 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
6401 before constructing arbiter.
6403 * eval.c (scm_m_define): Bugfix: Check that the object is a
6404 closure before setting the procedure property!
6406 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
6408 * ports.c: Removed `ungetc-char-ready?'.

6412 * read.c (scm_init_read): intitialise scm_read_hash_procedures
6413 (idea from Mikael: make it a pair so scm_permanent object only
6415 (scm_read_hash_extend): don't call scm_permanent_object.
6416 (ideas from Mikael): if chr is already in the list, replace its
6417 procedure instead of appending it again. If proc is #f, remove
6419 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
6421 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
6423 * gdbint.c (gdb_read): update scm_lreadr usage.

6437 for extended # processing.
6438 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
6439 scm_read_token): remove case_i, sharp arguments. Change callers.

6448 to determine whether to convert symbol case.
6449 (default_case_i): definition removed.
6450 * read.c (scm_read_token): if case_i, downcase ic before doing
6453 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6455 * configure.in: Added configuration option `guile-debug'.
6456 Configure with --enable-guile-debug if you want a bunch of extra
6457 functions used for debugging when developing Guile.
6459 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
6461 * procs.c (make-cclo): New undocumented debugging procedure: Make
6462 compiled closure with internal procedure PROC and length LENGTH.
6463 Only compiled if GUILE_DEBUG is defined.
6465 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
6467 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
6469 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
6471 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
6472 with 3 or more args internally to the evaluator.
6474 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6476 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
6477 with 3 or more args internally to the evaluator. This is mainly
6478 because we don't want to pass entry and exit points of the
6479 debug support twice, but it also seems to increase the speed of
6480 the evaluator for such calls (e. g. (+ 1 2 3)).
6482 * backtrace.c (scm_display_application): New procedure:
6483 display-application; Set fancy printing parameters individually
6484 for different types of display (backtrace, error, application).
6485 (These should of course be customizable!)
6487 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
6488 clear the CHECK-flags.
6490 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6492 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
6494 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6496 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
6497 from pairs with a GLOC in the car.
6499 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
6500 otherwise `symbol-hash' will behave badly.
6501 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
6502 we get segmentation fault!
6504 * symbols.c: Added #include "weaks.h". New functions:
6505 `builtin-bindings' and `builtin-weak-bindings'. (These will be
6506 moved to an extraneous library when we split libguile.)
6508 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6510 * filesys.c (scm_stat): stat now takes fport arguments too as
6511 documented in the manual.
6513 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6515 * debug.c (scm_single_step): Bugfix: Call continuation with
6516 scm_call_continuation instead of throwing to it.
6518 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
6520 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
6521 argument wasn't declared to be optional.
6523 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6525 * stime.c (scm_init_stime): Add feature "current-time".
6527 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6529 * throw.h: prototype for scm_exit_status.
6530 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
6531 args to derive an exit status. Allows (quit) to work from a
6533 (scm_exit_status): new function.
6536 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6538 * eval.c (scm_deval): Removed some old code.
6539 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
6541 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
6544 * symbols.c (msymbolize): Bugfix: Must initialize property list to
6547 * procs.c: Introduce the existent C function scm_thunk_p at the
6548 Scheme level as well.
6550 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6552 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
6553 used from C to easily lookup the value of a symbol in the current
6556 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6558 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
6559 scm_init_unif in this file. This will also fix a previous problem
6562 * configure.in: Added AM_MAINTAINER_MODE
6564 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6566 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
6569 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6571 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
6572 source files that are not always included in libguile but should
6573 have their dependencies calculated by automake. This variable is
6574 recognized by automake, no further magic is needed.
6575 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
6576 to deal exclusively with *.lo files, as it seems. The *.o files
6577 are built automatically when the corresponding *.lo file gets
6580 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
6582 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
6585 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
6587 * unif.c (scm_array_set_x): minor change to argument error checking.
6589 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
6591 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
6592 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
6593 They should only be included in the library at configure.in's
6595 (libguile_la_LDADD): Include the appropriate .lo files here.
6596 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
6597 so we know when to build them (and their .lo bretheren).
6598 * configure.in (LIBLOBJS): New substituted variable. We let
6599 configure decide which .o files to include in LIBOBJS, and then
6600 put the corresponding list of .lo files in LIBLOBJS. The latter
6601 is what we pass to libtool.
6602 * Makefile.in, configure: regenerated.
6604 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
6606 * symbols.c (scm_sysintern0): New function. Contains the core of
6607 old scm_sysintern but doesn't take a second value argument.
6608 (scm_sysintern): Now uses scm_sysintern0.
6609 (scm_sysintern_no_module_lookup): Renamed to
6610 scm_sysintern0_no_module_lookup and doesn't take a second value
6611 argument any longer.
6613 * symbols.h (scm_sysintern0: Added declaration.
6615 * options.c (scm_init_opts): Use scm_sysintern0 instead of
6616 scm_sysintern when interning option keys. Otherwise we risk
6617 destroying the values of already interned variables.
6619 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
6620 scheme-level boolean (use SCM_NFALSEP).
6622 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
6624 (scm_backtrace): New function. (C version of old function from
6625 boot-9.scm) Motivation: Make it possible to display backtraces
6626 without depending on boot-9.scm. (I'm uncertain if this
6627 motivation is good enough...)
6629 * root.h (scm_root_state): Add member the_last_stack_var.
6630 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
6632 * root.c (mark_root): Mark scm_the_last_stack_var.
6634 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
6637 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
6639 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
6640 1. mark_lazy_catch didn't mark the smob.
6641 2. Both functions above have standard variants:
6642 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
6643 free_lazy_catch --> scm_free0.
6645 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
6647 * throw.c (scm_internal_lazy_catch): New function.
6648 (scm_lazy_catch): Rewritten to use it.
6649 (scm_ithrow): Handle the new lazy catch representation.
6650 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
6651 that doesn't have a jmpbuf is a lazy catch clause.
6652 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
6653 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
6654 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
6656 (scm_init_throw): Register the new lazy-catch smob type.
6657 * throw.h (scm_internal_lazy_catch): decl for new function.
6659 * throw.c (scm_internal_catch): Doc fixes.
6661 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
6662 configure.in. Including this might cause problems if applications
6663 that link against libguile include their own copies of alloca, but
6664 if they're using autoconf, they should be adding libguile to LIBS
6665 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
6666 the copy in libguile, and things will be okay. (I think.)
6668 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6670 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
6672 strop.h: move prototypes too.
6674 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6676 * posix.c (scm_init_posix): don't intern EINTR since it's now done
6679 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
6680 etc. I deleted them from filesys.c long ago, but didn't
6681 notice they were here too (although ineffective since
6682 sys/stat.h wasn't included).
6684 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
6686 * eval.c: Don't define alloca in GCC case. gcc will automatically
6687 use __builtin_alloca if appropriate.
6689 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
6691 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
6692 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
6693 that values of automatic variables are preserved. See comments
6694 for safe_setjmp for details.
6696 Change from Thomas Morgan:
6697 * variable.c: Include eq.h.
6698 (var_equal): New function.
6699 (variable_smob): Use var_equal as the discriminator for variables.
6701 * throw.c (s_throw): Remove extraneous declaration.
6703 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
6704 * eval.c: Add necessary CPP cruft to support that.
6705 * configure, Makefile.in, scmconfig.h.in: regenerated.
6707 Change from Thomas Morgan:
6708 * procprop.c (scm_procedure_properties): Convert the Scheme
6709 boolean returned by scm_procedure_p into a C boolean before using
6710 it as a condition for SCM_ASSERT.
6711 (scm_procedure_property): Likewise.
6713 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
6714 indications of Unixness.
6717 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6719 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
6721 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6723 * read.c (scm_lreadr): use scm_misc_error to improve one of the
6724 "unknown # object" error messages.
6726 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
6727 (scm_i_index) and declare it static. Add a 'direction' argument
6728 to indicate what way the search should go.
6729 (scm_i_index): throw out-of-range error instead of wrong-type-arg
6731 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
6732 strop.h: remove scm_i_index, scm_i_rindex prototypes.
6734 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6736 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
6738 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
6739 to avoid clash with various scsh forks.
6741 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
6743 The following two changes (ramap.c, throw.c) are motivated by the
6744 apparent unportability of forward declarations of static arrays of
6745 the form `static foo bar[];'.
6747 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
6748 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
6750 * throw.c (scm_throw): Moved above scm_ithrow.
6752 * options.h: Removed the extern declarations of scm_yes_sym and
6753 scm_no_sym since these are static.
6755 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6757 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
6759 * Makefile.am: remove AWK=@AWK@.
6760 Add a rule for generating errnos.list.
6761 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
6763 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
6764 don't extract errnos, just set a variable (avoids the
6765 need to recompile error.c just because configure is run.)
6767 * unif.h: update prototypes.
6768 * unif.c (scm_uniform_array_read,write): change the offset and
6769 length arguments to start and end, for consistency.
6771 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
6773 * ioext.h: update prototypes.
6774 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
6775 scm_read_line_x, it's a more general procedure using an
6776 interface from scsh. read-line and read-line! are now defined
6778 Note that the new read-line trims the terminator
6779 by default, previously it was appended to the returned string. An
6780 optional argument specifies how to process the terminator (scsh
6781 compatible). For the old behaviour: (read-line port 'concat).
6782 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
6783 returns a pair, but is converted to multiple values if the scsh
6786 socket.h: update prototypes.
6787 * socket.c (scm_recvfrom): for consistency with other procedures,
6788 take start and end as separate optional arguments.
6789 (scm_recv, scm_recvfrom): don't allow the second argument
6790 to be a size, only a buffer. Change the scheme names to
6791 recv! and recvfrom!. Don't return the buffer.
6793 * ioext.h, posix.h: move prototypes too.
6794 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
6795 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
6796 "read.h" and "unif.h".
6797 * ioext.c: include "chars.h"
6799 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
6801 * dynl.c: The dynamic linking and module registration functions
6802 are now defined even when dynamic linking is not available for the
6803 host system. Some of their functionality can be done without
6804 dynamic linking; when it's really needed, they throw errors.
6806 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
6808 * configure.in: Only define DYNAMIC_LINKING when one of the system
6809 dependent functions is detected.
6810 * dynl.c (scm_dynamic_func): New function to get the address of a
6811 function in a dynamic object.
6812 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
6813 produced by scm_dynamic_func as the thing to call.
6815 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
6817 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
6818 (scm_register_module_xxx, scm_registered_modules,
6819 scm_clear_registered_modules): New functions.
6821 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
6823 * symbols.c (scm_sysintern): Renamed to
6824 scm_sysintern_no_module_lookup.
6825 (scm_sysintern): New function to take the place of the old
6826 scm_sysintern. It uses the current toplevel lookup closure to give
6827 the symbol its value. This is a temporary hack to put packages
6828 like gtcltk into their own module.
6829 (scm_can_use_top_level_lookup_closure_var): New variable to tell
6830 us whether `scm_top_level_lookup_closure_var' has been initialized
6832 * eval.c (scm_init_eval): Set it.
6834 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6836 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
6837 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
6839 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
6841 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
6842 scm_sys_dup): deleted: FD capability will be added to other
6844 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
6845 scm_fd_free, fd_smob, scm_intern_fd.
6846 (scm_open): renamed from scm_sys_open. Return a port instead of
6847 an FD object. Make the mode argument optional.
6848 (scm_sys_create): deleted, it's just a special case of open.
6849 (scm_init_filesys): move interning of constants O_CREAT etc.,
6850 here (were previously using SCM_CONST_LONG macro).
6851 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
6853 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
6854 include "fports.h" and <stdio.h>
6855 (scm_stat, scm_select): don't support FD objects.
6857 * error.h: adjust scm_syserror_msg prototype.
6858 * error.c (scm_syserror_msg): take an extra argument for errno.
6859 Using the global value didn't always work, since it could be
6860 reset by procedure calls in the message or args arguments.
6862 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
6863 I don't understand why the check was there (and what about the
6866 * strop.c (scm_string_copy): allow shared substrings to be copied.
6868 * unif.h: corresponding change to prototypes.
6869 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
6870 recognize two new optional arguments: offset and length. Allow
6871 the port argument to be an integer (file descriptor, for scsh).
6872 Include <unistd.h> for "read" prototype.
6874 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6876 * socket.c: don't include filesys.h.
6878 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6880 * Makefile.am: add AWK=@AWK@ (?)
6882 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6884 Add a rule to generate errnos.c from errnos.
6885 * error.c (scm_init_error): include errnos.c.
6886 * errnos_cnvt.awk: new file, converts the list of errno codes to
6888 * errnos_get.c: new file.
6889 * errnos.default: new file, contains errnos to try if they can't
6890 be extracted from errno.h.
6891 * configure.in: if using GCC, try and extract errno codes from
6895 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6897 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
6898 * Makefile.am: Made libguile into a libtool library.
6899 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
6900 Set libtool_libs to indicate that libguile is a libtool library.
6901 See guile/ChangeLog for details.
6902 * .cvsignore: ignore "*.lo", the libtool library objects.
6904 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6906 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
6907 use htons in getservbyport argument.
6909 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6911 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
6912 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
6915 * objprop.c (scm_object_property): No need to take the CDR of the
6916 value returned by scm_object_properties, since Aug 20 change.
6918 * configure.in: When checking for struct linger, #include
6919 <sys/types.h> as well as <sys/socket.h>. I've never known
6920 <sys/types.h> to cause any portability problems, and Solaris's
6921 <sys/socket.h> needs it.
6922 * configure: Rebuilt.
6924 I think the Sun compiler has chosen a perverse way to interpret
6925 ANSI declarations combined with K&R definitions. We'll
6926 appease it a little bit. But when it invades France, we fight.
6927 * print.c (scm_iprlist): Change 'tlr' argument to an int.
6928 * print.h (scm_iprlist): Here too.
6929 * numbers.c (scm_divbigdig): Change definition to match
6930 declaration in numbers.h.
6931 * unif.c (scm_makflo): Change definition to match declaration in
6934 * init.c (scm_boot_guile): Don't return the value of
6935 scm_boot_guile_1. This function doesn't return a value;
6936 scm_boot_guile_1 doesn't return a value (or return at all).
6938 * eval.c (unmemocopy): Add a semicolon to appease the Sun
6941 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
6942 compile. I have a feeling this function is a bad idea anyway ---
6943 one should always test for features, not systems.
6945 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
6946 semicolons. Only pure luck kept this from being noticed earlier.
6948 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
6950 * socket.c (scm_recvfrom): Added missing semicolon.
6952 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
6954 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
6955 the buffer and start and end positions for scsh networking
6958 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
6960 * configure.in: Revert previous change to this file; the problem
6961 is due to transient automake weirdness.
6962 * configure: Rebuilt.
6964 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
6965 PLUGIN/guile.libs. configure generates the latter from the former.
6966 * Makefile.in: Rebuilt.
6968 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
6969 need this if we install scripts, like guile-snarf.
6970 * configure: Rebuilt.
6972 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6974 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
6976 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
6978 * socket.c (scm_addr_vector): fix faulty scm_listify.
6980 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
6982 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
6983 style block comment is no longer considered an error.
6985 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
6987 * PLUGIN/guile.libs.in: New file.
6988 * PLUGIN/guile.libs: Removed from repository.
6989 * configure.in: Create PLUGIN/guile.libs from
6990 PLUGIN/guile.libs.in. This is for including additonal libraries
6991 needed for dynamic linking.
6992 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
6993 instead of PLUGIN/guile.libs.
6995 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
6997 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
6999 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
7000 occurrences of the given element from the list, not just the
7001 first. This is how the Emacs Lisp functions behave, how the
7002 analogous Common Lisp functions behave, and (I believe) how the
7003 older Maclisp functions worked. I realize that this change may
7004 break code, but it seemed better to break it before the Guile
7007 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
7008 Their prototypes were already present in gc.h, but they weren't
7010 (scm_init_storage): Initialize scm_protects.
7011 * root.c (scm_protects): New element of scm_sys_protects.
7013 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
7015 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
7017 * libguile.h: Added #include "libguile/net_db.h".
7019 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
7020 30 change. That file is only meant for communication between the
7021 configuration process and load.c. If code linked against libguile
7022 wants to get at the paths mentioned in libpath.h, it can call
7023 functions declared in load.h.
7025 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7027 * libguile.h: Removed #include "libguile/fdsocket.h"
7029 * net_db.c: Added #include <sys/socket.h>.
7031 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
7033 * filesys.c (scm_input_waiting_p): use select in preference to
7034 FIONREAD, since the latter doesn't detect EOF.
7035 Throw error if neither select nor FIONREAD available.
7037 * socket.c (scm_connect): take a port, not a fd object.
7038 (scm_fill_sockaddr): throw an error if fam is not recognised.
7039 (scm_bind): use scm_fill_sockaddr.
7040 (scm_listen): take a port, not a fd object.
7041 (scm_accept): take and return a port. return #f in the car if
7042 address can't be got
7043 (scm_sock_fd_to_port): new procedure.
7044 (scm_socket): use scm_sock_fd_to_port.
7045 (scm_addr_vector): throw error if unrecognised address type.
7046 take an extra argument with the calling procedure name.
7047 (scm_getsockname): take a port. return #f if address can't be got.
7048 (scm_getpeername): take a port. return #f if address can't be got.
7049 (scm_recvfrom): take a port. return #f for address component if can't
7051 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
7052 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
7054 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
7056 * throw.c (scm_internal_catch): Make body funcs and handler funcs
7057 use separate data pointers, to allow them to be designed
7058 independently and reused.
7059 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
7060 Renamed from catch_body, catch_handler, and uncaught_throw; made
7062 (struct scm_catch_body_data): Renamed from catch_body_data; moved
7064 (scm_catch): Use the above.
7065 (scm_throw): Don't bother printing a message for an uncaught
7066 throw; we establish a default handler in init.
7067 * throw.h (scm_internal_catch): Prototype updated.
7068 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
7070 (struct scm_body_thunk_data): New structure, used as data
7071 argument to scm_body_thunk.
7072 * init.c (struct main_func_closure): New structure, packaging up
7073 the data to pass to the user's main function.
7074 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
7075 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
7076 scm_internal_catch to establish a catch-all handler, using
7077 scm_handle_by_message. This replaces the special-case code in
7079 (invoke_main_func): Body function for scm_internal_catch; invoke
7080 the user's main function, using the main_func_closure pointer to
7081 decide what to pass it.
7082 * root.c (struct cwdr_body_data): Remove handler_proc member.
7083 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
7084 (cwdr_handler): Removed.
7086 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
7088 * socket.h (SCM_P): update bind prototype.
7089 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
7090 include "feature.h".
7091 (scm_socket): return a port, not a file descriptor object.
7092 include "fports.h" and <unistd.h>
7093 (scm_bind): take a port, not a file descriptor object.
7094 take an extra argument for address args.
7096 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
7097 INADDR_NONE, INADDR_LOOPBACK.
7099 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
7101 * init.c: include net_db.h and not fdsocket.h.
7102 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
7104 * Makefile.am: corresponding changes.
7105 * socket.h: renamed from fdsocket.h, fix names.
7106 * net_db.h: renamed from socket.h, fix names.
7107 * socket.c: renamed from fdsocket.c.
7108 remove _sys from procedure names.
7109 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
7110 add "socket" to features list.
7111 * net_db.c: renamed from socket.c.
7112 remove _sys from procedure names.
7113 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
7114 add "net-db" to features list.
7115 include "net_db.h". don't include <sys/socket.h> or
7118 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7120 * tags.h (scm_tags): Removed comma at end of last enumerator.
7122 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
7124 Don't use GCC extensions to allocate space for debugging frames.
7125 (Here he goes again! Why do we put up with this?!)
7126 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
7127 an scm_debug_info structure, not an in-line array of them. Add
7128 'info' member, to say how many vect elements we've used, for eval
7130 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
7131 a new variable debug_info_end to mark the end of vect, instead of
7132 the address of the 'info' pointer itself.
7133 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
7134 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
7135 (SCM_APPLY): Explicitly allocate space for debug.vect.
7136 * debug.c (scm_m_start_stack): Same, for vframe.vect.
7137 * stacks.c: Adjusted for new debug frame structure.
7138 (RELOC_INFO, RELOC_FRAME): New macros.
7139 (stack_depth, read_frames): Use them, and new scm_debug_frame
7140 element 'info', instead of magically knowing that eval frames have
7141 an info pointer sitting after vect.
7142 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
7144 (scm_init_stacks): Formatting tweaks.
7146 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
7148 Give GCC more control flow information, so it can be sure that
7149 variables aren't used uninitialized.
7150 * error.h (scm_error, scm_syserror, scm_syserror_msg,
7151 scm_sysmissing, scm_num_overflow, scm_out_of_range,
7152 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
7153 scm_misc_error): Tell GCC that these functions never return.
7154 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
7155 out the field type, call abort if SCM_ASSERT returns, to placate
7157 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
7158 scm_wta ever returns. We can't handle this case anyway, and this
7159 gives the optimizer more information.
7160 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
7161 scm_wta ever returns.
7163 In some cases, the code is fine, but GCC isn't smart enough to
7164 figure that out; this usually happens when one variable is only
7165 initialized and used when a particular condition holds true, and
7166 we know that condition will never change within a given invocation
7167 of the function. In this case, we simply initialize the variables
7168 to placate the compiler, hopefully to a value which will cause a
7169 crash if it is ever actually used.
7170 * print.c (scm_iprin1): Initialize mw_pos.
7171 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
7172 * throw.c (scm_ithrow): Initialize dynpair.
7173 * unif.c (scm_uniform_vector_ref): Initialize cra.
7174 * struct.c (init_struct): Initialize prot.
7175 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
7177 * strports.c (scm_eval_0str): Don't return uninitialized garbage
7178 if EXPR contains no expressions.
7180 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
7182 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
7183 cause an infinite loop (???). So much for the algebraic
7184 equivalency of variable-sized arrays and alloca...
7186 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
7188 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
7189 a SCM boolean, not a C boolean.
7191 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
7193 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
7194 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
7195 rules for raising scm_mtrigger. Previously, unfortunate but not
7196 unlikely circumstances could result in almost constant invokation
7197 of the gc. Now, this situations should be less likely, but they
7198 are not prevented completely.
7200 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
7202 * numbers.c (scm_fuck): Procedure removed; looks like old test
7204 * numbers.h: Prototype removed.
7206 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
7208 * debug.h (scm_debug_frame): Change `vect' member from an in-line
7209 array to a pointer, to match my Nov 21 change in eval.c.
7211 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7213 * libguile.h: Added #include "libguile/backtrace.h", #include
7214 "libguile/stacks.h".
7216 * strings.c (scm_string scm_make_string scm_string_ref
7217 scm_string_set_x scm_string_equal_p scm_string_append):
7218 Bugfix according to scm patch from Aubrey Jaffer:
7219 Corrected long-standing
7220 (not (eqv? (integer->char 128)
7221 (string-ref (make-string 1 (integer->char 128)) 0)))
7222 bug found by John Kozak <jk@noontide.demon.co.uk>.
7224 * strports.c, strports.h: Make scm_eval_0str return the value of
7225 the last expression evaluated (previously, it returned void).
7227 * strports.c, strports.h: New function: scm_read_0str. Does what
7230 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7232 * simpos.c (scm_getenv): return #f if string can't be found in the
7233 environment instead of throwing an exception, for compatibility
7234 with numerous other systems.
7236 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
7238 * Makefile.am (.c.x): Use guile-snarf.
7239 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
7241 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
7243 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
7245 * backtrace.c (scm_display_error_message): Made non-static, and
7246 renamed from display_error_message.
7247 * backtrace.h (scm_display_error_message): Added extern decl.
7248 * throw.c (uncaught_throw): Use it to display the error message.
7250 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
7252 * inet_aton.c: Use #if 0, not #ifdef 0.
7254 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
7256 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
7257 to convert the returned value.
7258 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
7259 the offset argument.
7261 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
7263 Add new interface to catch/throw, usable from C as well as
7265 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
7266 (scm_internal_catch): New function, replaces...
7267 (scm_catch_apply): Deleted.
7268 * throw.c (scm_catch_apply): Deleted; replaced with a more general
7269 mechanism which is a bit more code, but can be used nicely from C
7270 and implement the Scheme semantics as well.
7271 (scm_internal_catch): This is the replacement; it's named after
7272 the analogous function in Emacs.
7273 (scm_catch): Reimplemented in terms of the above.
7274 (struct catch_body_data, catch_body, catch_handler): New
7275 functions, used by scm_catch.
7276 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
7277 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
7278 support for new cwdr.
7280 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
7283 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
7285 * acconfig.h: Added DYNAMIC_LINKING symbol.
7286 * configure.in: Add option and checks for dynamic linking.
7287 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
7288 dynl.h: New files for dynamic linking support.
7289 * Makefile.am (libguile_a_SOURCES):
7291 (modinclude_HEADERS): Added "dynl.h".
7292 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
7294 * init.c (scm_boot_guile_1): Call
7295 scm_init_dynamic_linking to initialize dynamic linking support.
7297 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
7299 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
7300 (as we Schemers say). It needs to be global, so that I can tweak
7301 it for the proper operation of unexec.
7302 (scm_boot_guile_1_live): New variable, see above.
7304 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
7306 * guile-snarf.sh: Removed.
7307 * PLUGIN/guile.libs: Added dependency for -lm.
7308 * acinclude.m4: Renamed from aclocal.m4.
7309 * PLUGIN/greet: Removed.
7310 * Makefile.am, aclocal.m4: New files.
7311 * configure.in: Updated for Automake.
7313 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
7315 * eval.c (scm_definedp): Use top_level_lookup_closure_var
7316 and not top_level_lookup_thunk_var.
7318 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
7320 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
7322 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
7324 * eval.c (scm_definedp): Incompatibly changed to be a builtin
7325 Scheme function, instead of syntax. Single argument is now a
7328 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7330 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
7331 scm_ra_divide): Properly terminate statements passed as arguments
7332 to IVDEP macros. (Thanks to Bernard Urban.)
7334 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
7335 with non-constant sizes. (Thanks to Bernard Urban.)
7337 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
7339 It's an "eval closure", not an "eval thunk." A thunk is a
7340 function of no arguments.
7341 * root.h (struct scm_root_state): Renamed
7342 top_level_lookup_closure_var from top_level_lookup_thunk_var.
7343 (scm_top_level_lookup_closure_var): Renamed from
7344 scm_top_level_lookup_thunk_var.
7345 * root.c (mark_root): Uses changed.
7346 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
7347 * init.c (scm_start_stack): Uses changed.
7348 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
7349 Change scheme-visible name to *top-level-lookup-closure* from
7350 *top-level-lookup-thunk*.
7352 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
7354 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
7355 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
7357 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
7359 * gc.c (struct scm_heap_seg_data): Doc fixes.
7361 * gc.c (scm_gc_sweep): Empty all segments' freelists before
7362 sweeping. Then, prepend each segment's free cells to its
7363 freelist, rather than wiping out the old value. (Thanks to Marius
7366 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
7367 scm_check_freelist, scm_debug_newcell): New functions and
7368 variables, for debugging freelist problems.
7369 * pairs.h (SCM_NEWCELL): New debugging version added.
7370 * gc.h (scm_debug_newcell): Added extern declaration, used by
7371 debugging version of SCM_NEWCELL.
7373 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7375 On some systems <libc.h> conflicts with <unistd.h>, and should not
7376 be #included at all.
7377 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
7378 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
7379 * configure.in: Call it.
7380 * posix.c, filesys.c: Use its results to decide whether or not to
7382 * configure, scmconfig.h.in: Rebuilt with autoconf and
7385 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7387 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
7388 pointer to the stdio stream before calling scm_setbuf0, so the
7389 latter will be able to retrieve it. I'm surprised this didn't
7390 segfault earlier. (Thanks to Christopher Lee.)
7392 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7394 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
7397 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7399 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
7400 number of stack narrowing specifier pairs. The first specifier in
7401 a pair controls inner border, the second the outer border. A
7402 number means cut that number of frames, a procedure object means
7403 cut until that object is found in operator position in a frame.
7405 * root.c (cwdr): Bugfix.
7407 * read.c: Recording of positions disabled by default.
7409 * procs.c (scm_closure_p): New function.
7411 * posix.c (scm_tmpnam): New function.
7413 * load.c: Added #include "throw.h".
7414 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
7417 * load.c, load.h (scm_read_and_eval_x): New function.
7419 * eval.c: Renamed debug option "deval" to "debug".
7421 (scm_eval_x): `eval!' is no longer accessible from the scheme
7422 level. Motivation: We can't allow operations which introduce
7423 glocs into the scheme level. Guile's type system can't handle
7424 these as data. Use `eval' or `read-and-eval!' as replacement.
7426 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
7427 SCM_CONSP since this is a macro!; Set vframe.prev to
7428 scm_last_debug_frame instead of 0. In this way we can look
7429 "above" the virtual start stack frame if we wish.
7430 (scm_debug_hang): New function: Useful for debugging Guile in
7431 certain tricky situations. Will probably be removed later...
7433 * debug.h: Changed semantics of debug option "backtrace". This
7434 option now only indicates whether we want automatic backtrace at
7437 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7439 * ports.c: #include "filesys.h"
7440 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
7442 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
7443 Motivation: This is system specific code which is related to file
7444 I/O. It also may use select. Added code by Gary Houston to
7445 detect presence of character in stdio buffers.
7447 * libguile.h: #include "libguile/libpath.h"
7449 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
7450 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
7451 SCM_SITE_DIR; Install libpath.h among the other include files.
7453 * load.c, load.h (scm_sys_package_data_dir): New function.
7455 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7457 * stacks.h: Bugfix: Don't use tail-array length field as stack
7458 length field! This screwed GC.
7460 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7462 * _scm.h: Added #ifndef around definition of macros min and max.
7464 * __scm.h: Added hooks for threads to plugin to in ints protection
7465 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
7466 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
7467 the main code in these macros duplicated and spread over multiple
7468 files. Renamed SCM_THREADS_SWITCHING_CODE ->
7469 SCM_THREAD_SWITCHING_CODE.
7471 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
7473 * snarf.h: New file.
7474 * guile-snarf.sh: New file.
7475 * Makefile.in (inner_h_files): Added snarf.h
7476 (ancillary, install, uninstall, distclean): Added actions for
7478 (.c.x): Use guile-snarf.
7479 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
7480 (gen_c_files): Note that these depend on guile-snarf.
7481 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
7482 now in "snarf.h". Added #include "snarf.h" to get them.
7483 * libguile.h: Added #include "snarf.h".
7484 (Patches applied and tweaked by Jim Blandy.)
7486 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7488 * socket.c: Use K&R style declaration for 'close'; the GNU coding
7489 standards suggest against providing prototypes for system
7490 functions. Thanks to Greg Troxel.
7492 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
7494 * strports.c (scm_eval_0str): New function.
7495 #include "read.h", to get prototype for scm_read.
7496 * Makefile.in (strports.o): Update dependencies.
7497 * strports.h: New prototype.
7499 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
7500 scheme name from "int?" to "integer?". It seems to do the job.
7501 * numbers.h: Rename prototype too.
7502 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
7505 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
7506 scm_num_eq_p): Rename these according to R4RS conventions: call
7507 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
7508 to making libguile R4RS compliant without ice-9...
7510 * load.c (scm_sys_search_load_path): Search for files under all
7511 extensions listed in the %load-extensions variable. If FILENAME
7512 is absolute, return it unchanged, without searching the load path.
7513 (scm_loc_load_extensions): New variable, pointing to
7514 %load-extensions' value cell.
7515 (scm_init_load): Initialize it, and the value it points to.
7516 (scm_primitive_load_path): Improve error reporting.
7518 * load.c (scm_loc_load_hook): New variable, pointing to value cell
7519 of new Scheme variable %load-hook.
7520 (scm_primitive_load): Apply %load-hook to filename.
7522 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
7524 * configure.in: add tests for figuring out whether buffered data
7525 is available in a FILE structure, which is needed by char-ready.
7527 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
7530 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
7531 exceptions using misc_error instead of syserror. It seems a bit
7532 odd to throw an exception if a string can't be found in the
7533 environment, but it's consistent with open-file, stat etc.
7534 (simpos.h): remove sys_ from getenv.
7536 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
7537 occurs, throw an error instead of returning errno. Return value
7539 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
7541 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
7543 * filesys.c (scm_stat2scm): derive file type and permissions from
7544 the stat mode and append them to the returned vector.
7545 There isn't much overhead in doing this and it avoids the need to
7546 work with S_IRUSR et al. in Scheme.
7547 Define symbols scm_sym_regular etc.
7548 (scm_init_filesys): don't intern S_IRUSR etc.
7550 * load.c: change s_try_load and s_try_load_path to s_primitive_load
7551 and s_primitive_load_path.
7553 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
7555 * error.h: don't declare error symbols. prototype for scm_misc_error.
7557 * stackchk.c (scm_stack_overflow_key): defined here instead of in
7560 * error.c: use SCM_SYMBOL to set up error keys.
7561 scm_misc_error: new procedure.
7563 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
7565 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
7566 between `#!' and `!#' is ignored.
7567 (skip_scsh_block_comment): New function.
7569 * feature.c (scm_set_program_arguments): New argument, FIRST.
7570 * feature.h: Update prototype.
7571 * init.c (scm_boot_guile_1): Pass new argument to
7572 scm_set_program_arguments.
7574 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
7576 * init.c (scm_start_stack): Don't initialize scm_progargs here.
7577 (scm_boot_guile): Call scm_set_program_arguments here, later than
7578 the old initialization.
7580 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
7581 initialization procedure.
7582 - Delete in, out, err arguments; there are other perfectly good
7583 ways to override these when desired.
7584 - Delete result argument; this function shouldn't ever return.
7585 - Rename init_func argument to main_func, for less confusion.
7586 - Delete boot_cmd argument; main_func is more general.
7587 -Add 'closure' argument, to help people pass data to main_func
7588 without resorting to global variables.
7589 - Abort if reentered; don't bother returning an error code.
7590 - Call scm_init_standard_ports to set up the default/current
7591 standard ports; no need to pass them to scm_start_stack.
7592 - Remove code to evaluate the boot_cmd, and start the repl; let
7593 the user do something like that in main_func if they want.
7594 - Remove code to package up a return value; main_func can do any
7596 - Call exit (0), instead of returning.
7597 (scm_start_stack): Don't initialize the I/O ports here; that's
7598 weird. Delete in, out, err arguments. Move guts to
7599 scm_init_standard_ports, scm_stdio_to_port.
7600 (scm_init_standard_ports): New function, to set up current and
7601 default standard ports.
7602 (scm_start_stack, scm_restart_stack): Make these static.
7603 * init.h (scm_boot_guile): Adjust declaration.
7604 (scm_start_stack, scm_restart_stack): Remove externally
7605 visible declarations for these.
7606 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
7608 * fports.c (scm_stdio_to_port): New function. Its guts used to be
7609 written out several times in scm_start_stack.
7610 * fports.h: New declaration for the above.
7612 * feature.c (scm_set_program_arguments): New function.
7613 * feature.h: New declaration for the above.
7615 * ports.c: Formatting tweak.
7617 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
7619 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
7620 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
7621 for obtaining the address of a car or cdr field. Motivation:
7622 &SCM_CXR make assumptions about the internal structure of the
7625 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
7626 Motivation: see SCM_CXRLOC.
7628 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
7629 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
7630 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
7631 Motivation: Safer use. Some other macros are defined in terms of
7632 these operations. If these are defined using the SCM_SETCXR
7633 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
7634 to inefficiency and an <e1> with side-effects could potentially
7635 break. Also, these particular operations are heavily utilized in
7636 the garbage collector. In unoptimized code there will be a
7639 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
7640 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
7641 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
7642 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
7643 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
7644 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
7645 vports.c: Cleaned up use of pairs: Don't make any special
7646 assumptions about the internal structure of selectors and
7647 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
7648 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
7649 (Among other things, this change makes it easier to build Guile
7650 with certain compilers which have problems with casted lvalues.)
7652 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7654 * stacks.c: Improve selection of relevant stack frames when making
7655 a stack object. Introduce one level of indirection in the stack
7656 object to make it possible to "narrow" to a certain region of the
7657 stack. This facilitates making use of more clever algorithms (not
7658 implemented) for selecting relevant frames and gives a cleaner
7659 design since selection of frames can be done independently of
7660 extraction of frames from the real stack.
7661 (scm_stack_id): Also take #t as argument which means look at
7664 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
7665 Turn n_tail into an integer directly representing current number
7666 of frames in stack. Add field tail.
7668 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
7670 * debug.c (scm_make_memoized): Made it available at scheme level.
7671 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
7672 SCM_NIMP before applying heavier predicates in argument checking.
7673 (scm_local_eval): Also take memoized object as argument.
7675 * backtrace.c (scm_display_error): Just a safety measure: Stacks
7676 aren't created with zero length, but should such a strange
7677 creature suddenly turn up...
7679 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
7681 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
7682 `del', for the sake of C++ compilers. (Patch applied by JimB.)
7684 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
7686 * variable.c (scm_make_variable): Make the name hint optional, as
7688 (anonymous_variable_sym): Renamed from variable_sym. All uses
7691 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
7692 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
7693 of scm_primitive_load_path was also changed to
7694 "primitive-load-path", from "%try-load-path". Callers changed.
7695 We'd like to respect the convention that a function named
7696 "try-mumble" should behave just like the function called "mumble",
7697 but return #f instead of signalling some error.
7698 * load.h: Rename prototypes.
7700 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7702 * print.c (make_print_state, grow_print_state), print.h: Modified
7703 the print state representation: Don't use a tail array for
7704 recording of circular references. Resizing of the print state
7705 structure invalidates the print state pointer. To avoid passing
7706 around an indirect print state reference to all printing
7707 functions, we instead let the print state reference a resizable
7710 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7712 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
7713 Don't crash when passed an improper list terminated by a
7714 non-immediate value.
7716 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
7718 Allocate data for structures on an eight-byte boundary, as
7719 required by the tagging system.
7720 * struct.c (alloc_struct): New function.
7721 (scm_make_struct, scm_make_vtable_vtable): Call it.
7722 * struct.h (scm_struct_n_extra_words): Bump to 3.
7723 (scm_struct_i_ptr): New "field".
7724 * gc.c (scm_gc_sweep): When we need to free the data, use the
7725 information stored by alloc_struct to find the beginning of the
7726 block allocated to the structure, so we can free it.
7728 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7730 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
7733 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
7734 (scm_debug_info): New member: id.
7736 * stacks.c: Stacks are now represented as structs; Stacks have an
7737 id given to them by `start-stack'.
7738 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
7740 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
7741 Changed stack representation.
7743 * debug.c (scm_procedure_name): Try procedure property `name' for
7744 compiled closures aswell.
7746 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
7748 * eval.c: scm_i_name moved to gsubr.c
7749 (scm_m_define): Record names of all kinds of procedure
7750 objects. (Earlier, only closures were recorded.)
7752 * procprop.h: Added declaration of scm_i_name.
7754 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
7755 (scm_make_gsubr): Record names of compiled closures.
7757 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7759 * debug.c, debug.h: Removed obsolete code.
7761 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
7762 stacks.c: Renamed regs --> scm_contregs.
7764 * print.c (scm_free_print_state): Cleanup print state before
7765 returning it to pool. It is better to do it here than in
7766 scm_prin1 since scm_prin1 is called often.
7768 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
7769 s_set_source_property_x): Check that first argument is a pair or a
7772 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
7773 scm_i_line, scm_i_column and scm_i_breakpoint global.
7775 * init.c: Added #include "backtrace.h" and #include "stacks.h".
7776 (scm_boot_guile_1): Added calls to scm_init_backtrace and
7779 * debug.h: Added debug object smob declaration and macro
7782 * configure.in: Build with backtrace.o and stacks.o if debug
7785 * Makefile.in: Added entries for new files: backtrace.c,
7786 backtrace.h, stacks.c and stacks.h.
7788 * symbols.c (scm_sym2ovcell): Fixed documentation.
7790 * _scm.h (min, max): Added.
7792 * async.c: Moved `min' macro to _scm.h.
7794 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
7795 SCM_BACKTRACE_INDENT.
7797 * eval.c: Added new debug options `maxdepth' and `indent'.
7799 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
7801 * print.h: Added selector SCM_PRINT_STATE.
7803 * print.c: New functions: scm_make_print_state,
7804 scm_free_print_state.
7806 * print.h: Added declarations for scm_make_print_state,
7807 scm_free_print_state.
7809 * debug.c (scm_m_start_stack): New acro.
7811 * debug.h: Small cleanup.
7813 * init.c (scm_boot_guile_1): Moved scm_init_debug below
7816 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

7841 More prototype-related changes from Marius Vollmer:
7842 * gdb_interface.h: Wrapped header file in #ifdef/#endif
7843 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
7844 * ports.h (ptobfuns): Added prototypes. This means some casting in
7846 * fports.c: Added casts for initializations, since the functions
7847 are defined to take FILE * as their stream argument, not SCM.
7848 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
7849 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
7850 to `char *str_data' to conform to prototype.

7854 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
7856 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
7858 * stime.c, stime.h: use SCM_P method.
7860 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7862 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
7863 be given at least two arguments. Insist that lst's last element
7864 be a list, but don't make any requirements of its predecessors.
7866 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7868 * eval.c (scm_nconc2last): Revert last change; there seems to be
7869 other stuff going on here.
7871 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7873 * eval.c (scm_nconc2last): Make sure that each element of lst
7874 (which is a list of argument lists, except for the tail) is a
7875 proper list, i.e., finite and terminated by '().
7877 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7879 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7882 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7883 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7886 * vectors.c (scm_make_vector): Fill vectors with the undefined
7887 value, to help make Guile Scheme code more portable to other
7890 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7891 * symbols.h, tags.h: Doc fixes.
7893 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
7895 * async.c (scm_take_signal): Doc fixes.
7897 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
7899 * numbers.c (scm_divbigint): When the remainder is zero, we don't
7900 want to subtract it from the modulus; we just want to leave it
7903 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
7905 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
7908 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
7910 * throw.c (scm_catch_apply): Finished implementation of
7913 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7915 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
7917 (scm_init_filesys): set "i/o-extensions" feature.
7920 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
7922 * Makefile.in (root.o): Correct dependencies.
7924 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
7926 * Makefile.in: Added dependency entry for root.o.
7928 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
7929 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
7931 * init.c (scm_start_stack): Set initial root continuation number
7934 * procs.c: New function: scm_thunk_p.
7936 * procs.h: Added declarations of scm_thunk_p.
7938 * root.c: Renamed `call-with-new-root' -->
7939 `call-with-dynamic-root'.
7940 (cwdr): Removed allocation of new root state. This should be done
7941 separately by use of scm_make_root.
7942 (scm_apply_with_dynamic_root): New function: Does what it
7943 sounds like. Needed when spawning threads.
7945 * root.h: Added member last_debug_frame to root state.
7946 Added #include "libguile/debug.h"
7948 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
7949 arguments. The motivation is that code in root.c needs catch
7950 functionality, and we want to avoid code duplication.
7951 New functions: scm_catch, scm_lazy_catch. These are wrappers for
7952 scm_catch_apply. scm_lazy_catch is intended to introduce catch
7953 handlers that run without popping the stack into the dynwind
7956 * throw.h: Added prototypes for scm_catch_apply and
7959 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7961 * root.h (scm_root, scm_set_root): Decouple thread support details
7962 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
7963 SCM_SET_THREAD_LOCAL_DATA.
7965 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
7966 and tortoise scanning loop.
7968 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
7970 * Makefile.in: Rebuild dependencies.
7972 * libguile.h: #include "libguile/print.h" before "smob.h", since
7973 the latter uses the print_state structure.
7975 * throw.c (scm_ithrow): Use the correct variable when checking to
7976 see if a given element of scm_dynwinds is a valid catch.
7978 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
7979 structure, abort; don't just silently ignore the garbage.
7981 * _scm.h: #include "print.h" here, since it seems to be used just
7983 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
7984 strports.c, unif.h: Don't #include "print.h".
7986 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7988 * feature.h (scm_loc_features): Removed external declaration.
7989 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
7991 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7993 * feature.c (scm_init_feature): Added threads feature (needs to be
7994 initialized here, since features doesn't exist when
7995 scm_init_threads is called).
7997 * libguile.h: Added #include "libguile/../threads/threads.h".
7998 (This is a kludge to get thread support working. This should be
8001 * configure.in, acconfig.h: Added flags for thread support.
8003 * scmsigs.c: Define `signal' to be `pthread_signal' if using
8006 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
8007 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
8010 * _scm.h: Added conditional #include "threads.h"
8012 * __scm.h (SCM_ASYNC_TICK): Added call to macro
8013 SCM_THREADS_SWITCHING_CODE.
8015 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
8016 allocate the basic dynamic root object.
8017 (scm_boot_guile): Added call to scm_init_root.
8019 * root.c, root.h: Added root smob.
8020 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
8021 functions: Implements dynamic roots mostly according to spec in
8022 SCM manual. Main difference is that the second argument is a
8023 throw handler rather than an error "thunk".
8025 * root.h: Added declaration of scm_init_root.
8027 * root.c: Added #include "genio.h", #include "smob.h", #include
8028 "pairs.h", #include "throw.h", #include "dynwind.h", #include
8030 (scm_init_root): Added #include "root.x".
8032 * throw.c: Added #include "stackchk.h"
8033 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
8034 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
8035 can be used in scm_call_with_new_root; Added reenabling of stack
8036 checking when catching a throw.
8038 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
8040 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
8042 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
8043 element is not found, as per R4RS.
8045 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
8047 * list.c: Doc fixes throughout.
8049 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
8051 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
8052 declare the char * to be const. Avoids a warning in rgx.c.
8054 * ports.h: spelling fix.
8056 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
8059 * load.c (scm_sys_try_load_path): throw an error if file not found
8060 (like it says it in NEWS).
8062 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
8064 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
8065 PROPS slot to '(), not #f; it's an empty alist.
8067 * throw.h, throw.c: Use SCM_P instead of #if hair.
8069 Remove special support for uncaught throws; see throw.c for
8071 * throw.c (uncaught_throw): New function.
8072 (scm_ithrow): Call uncaught_throw if we don't find a throw
8073 target; don't mess with scm_bad_throw_vcell.
8074 (scm_bad_throw_vcell): Variable deleted.
8075 (scm_init_throw): Don't initialize it.
8077 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
8080 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
8082 * numbers.c (scm_istr2int): If the number is short (as most
8083 numbers are), just call scm_small_istr2int to deal with it.
8084 (scm_small_istr2int): New function, created by un-#ifdefing the
8085 non-bignum version of scm_istr2int and renaming it.
8087 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
8089 * load.c (scm_sys_try_load): don't check whether value returned
8090 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
8091 Change the Scheme name from %try-load to primitive-load.
8093 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
8094 Can avoid passing a message, allowing it to be derived in the
8095 error handler (e.g., if we want to throw to the key both from
8098 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
8100 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
8101 references now have a new appearance which is more compact and
8102 also gives a clue about what the target of the reference is.
8103 By setting parameters in the print state, more fancy printing can
8104 be achieved. This is used by the (not yet commited) backtrace
8107 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
8109 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
8112 * print.c: Added #include "struct.h". Removed function
8115 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
8116 scm_iprin1. Removed prototype for scm_prlist.
8118 * arbiters.c (prinarb),
8119 async.c (print_async),
8120 debug.c (prindebugobj, prinmemoized),
8121 eval.c (prinprom, prinmacro),
8122 filesys.c (scm_fd_print, scm_dir_print),
8124 mallocs.c (prinmalloc),
8125 numbers.c, numbers.h (scm_floprint, scm_bigprint),
8126 smob.h (scm_smobfuns),
8127 srcprop.c (prinsrcprops),
8129 unif.c, unif.h (scm_raprin1, rapr1),
8130 variable.c (prin_var): Changed argument `int writing' to
8131 `scm_print_state *pstate'.
8133 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
8134 that it will be called before scm_init_print.
8136 * print.c (scm_prin1): Print states are now allocated when calling
8137 scm_prin1 and then passed around to all printing functions as an
8138 argument. A cache `print_state_pool' enables reuse of print
8140 (scm_make_print_state): New function.
8141 (scm_iprin1): Adaption to print states.
8142 (scm_iprlist): An initial "hare and tortoise" scan brings down
8143 time complexity to O (depth * N). (Better time complexity will be
8144 achieved when the printing code is completely rewritten.)
8146 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
8148 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
8149 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
8150 it gets done whether or not the cache variable has a value.
8152 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8154 Distinguish #f and ().
8155 * __scm.h: #undef SICP.
8156 * pairs.h (SCM_EOL): Delete this definition, equating it with
8158 * tags.h (SCM_EOL): Give it a new definition here; I think I found
8159 the value it used to have. Doc fixes, too.
8161 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
8163 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
8164 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
8165 Lord's implementation of structs, allowing for tail arrays as
8166 described in the manual. Also fixed some bugs. (Both the interface
8167 and the implementation should be improved.)
8169 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
8171 * print.c, print.h: Closures now print like #<procedure foo (x)>.
8172 People who whish to see the source can do `(print-enable 'source)'.
8173 Removed #ifdef DEBUG_EXTENSIONS.
8175 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
8177 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
8178 integer (assuming for now accepting an integer is a good thing).
8180 * error.c, fports.c: replace use of %S in lgh_error args with %s.
8181 %S will be used instead for write'ing arguments.
8183 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
8184 asserts. fix a few other asserts.
8185 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
8186 scm_uniform_vector_ref, scm_array_set_x,
8187 scm_dimensions_to_unform_array): change args in
8188 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
8189 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
8190 scm_substring_fill_x): likewise.
8191 gsubr.c (scm_gsubr_apply): likewise.
8192 eval.c (SCM_APPLY): likewise.
8194 * eval.c (4 places): replace scm_everr with lgh_error or
8197 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
8198 scm_memory_error): new procedures.
8199 scm_everr: deleted. can use scm_wta, dropping first two args.
8200 scm_error: convert NULL subr to SCM_BOOL_F.
8202 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
8205 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
8208 * error.c, error.h: new error keys: scm_arg_type_key,
8209 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
8211 scm_wta: reimplement using lgh_error instead of scm_everr.
8213 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
8215 * gdbint.c: scm_lread now has one more argument.
8217 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
8218 scm_port_\1; Added mutator scm_set_port_filename_x (used when
8219 loading source from non-file ports, which, e. g., happens when
8220 using the Emacs interface).
8222 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
8225 * read.c: Added code for recording of positions of source code
8226 expressions; New functions: recsexpr, scm_lreadrecparen;
8227 _scm_make_srcprops --> scm_make_srcprops
8228 (scm_flush_ws): Removed updating of positions counters. This work
8229 is already done by scm_gen_getc
8231 * read.h: Added prototype for scm_lreadrecparen
8233 * print.c: Added #include "alist.h"
8235 * eval.c: Added #include "hash.h"
8237 * eq.c: Added #include "ramap.h"
8239 * options.c: Documentation fixes.
8241 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
8242 (scm_init_srcprop): Adjusted size of initial source-whash. Name
8243 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
8244 --> scm_make_srcprops
8246 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
8247 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
8248 function calls in the definition of the whash access macros.
8250 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
8252 * init.c (scm_boot_guile): Add level of indirection to
8253 scm_boot_guile_1() to ensure that stack base pointer is properly
8254 initialized. There was no guarantee that variable i was the
8255 highest/lowest variable on stack (i.e. the call frame of
8256 scm_boot_guile was not completely protected from gc).
8258 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
8260 * ports.h (scm_port_table): put back file_name, it will be used to
8261 support debugging. Undo related changes in fports.c, ioext.c,
8264 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
8266 * ports.h (scm_port_table): remove file_name member for now, it seems
8268 * fports.c (scm_open_file): don't set file_name in PTAB.
8269 (prinfport): don't use file_name in PTAB.
8270 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
8271 * ports.c (scm_add_to_port_table): don't intialize file_name.
8272 (scm_port_file_name): remove for now.
8273 * gc.c (scm_gc_mark): don't mark PTAB file_name.
8275 * fports.h (scm_mkfile): prototype deleted.
8276 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
8278 * debug.c, unif.c: use scm_out_of_range instead of
8279 wta for range errors (ASSERT still needs work).
8281 * error.c, error.h (scm_out_of_range): new procedure.
8283 * error.c, error.h (scm_out_of_range_key): new key.
8285 * posix.c (scm_sync): #else was missing.
8287 * error.c, error.h: append _key to names scm_num_overflow and
8290 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
8291 of consing an empty list.
8292 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
8293 of macros, saves code and string space.
8294 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
8295 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
8296 lower case. Rename scm_syserror_m to scm_syserror_msg.
8297 error.h: prototypes for new procedures.
8299 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
8301 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
8303 * error.c, error.h: setup scm_num_overflow key.
8305 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
8306 Remove definition of SCM_OVSCM_FLOW.
8308 * fports.c (scm_open_file): use SCM_SYSERROR_M.
8310 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
8311 explicit message and args.
8313 * error.c, error.h, __scm.h: change system_error_sym to
8316 * error.c (system_error_sym): remove leading %% from the Scheme name
8319 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
8321 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8323 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
8324 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
8325 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
8326 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
8327 renamed. (These were introduced by unsupervised name
8330 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8332 * print.c: Added code for detection of circular references during
8333 printing. (init_ref_stack, grow_ref_stack): New functions. Added
8334 a hook for printing of closures (accessible via print options).
8335 This leads to a split of calls to scm_iprin1 into two classes:
8336 elementary print operations (e. g. the code which prints a smob)
8337 still use scm_iprin1 while top level calls (like scm_display) use
8338 scm_prin1. scm_prin1 begins by clearing the data structure used
8339 to record reference information.
8341 * print.h: Added declarations of scm_prin1 and scm_prlist.
8343 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
8345 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
8347 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
8349 * error.c (err_head): scm_iprin1 --> scm_prin1
8351 * debug.c: Adjusted header comment.
8355 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
8357 * strerror.c: Doc fix.
8359 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8361 * gdbint.c (gdb_read): Now possible to run during GC.
8362 (unmark_port, remark_port): New functions.
8364 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
8366 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
8367 of allocating a new string object. Also, increase size by
8368 the factor 2 instead of 1.5.
8370 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
8372 * __scm.h (SCM_P): Corrected to run under traditional C.
8374 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
8377 * async.c: Calls to scm_sysintern corrected.
8379 * async.h (scm_async_clock): Redundant declaration removed.
8381 * continuations.c (scm_dynthrow): Redundant declaration removed.
8383 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
8384 Definition typos corrected.
8386 * debug.h: Missing declarations of functions in debug.c added
8389 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
8390 Missing declarations to functions in eval.c added.
8392 * filesys.c: Possibly uninitialized variable rv.
8394 * gc.h (scm_object_addr, scm_unhash_name): Missing
8395 declarations of functions defined in gc.c added.
8397 * genio.c: Possible typos str_data -> wstr_data. ???
8399 * genio.c: Possibly unintended shadowing of local variable
8400 `int c' (gotos out of scope of inner `c'). ???
8402 * init.c: Uninitialized `SCM last' may be used.
8404 * ioext.h: (scm_sys_isatty_p): Typo.
8406 * list.h (scm_list_head): Missing prototype for function in
8409 * numbers.c (scm_two_doubles): Changed from extern to static
8410 (is used only within numbers.c).
8412 * numbers.h: Repeated declarations removed.
8414 * ports.h (scm_close_all_ports_except): Declaration for the
8415 function defined in ports.c added.
8417 * posix.h: Missing declarations added.
8419 * procs.h (scm_make_subr_opt): Missing declaration added.
8421 * socket.h (scm_sys_gethost): Missing declaration added.
8423 * socket.h: Redundant declarations removed (they are in fdsocket.h).
8425 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
8426 Missing declarations added.
8428 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
8430 * struct.c: Uninitialized variable `SCM answer' may be used.
8432 * unif.c (l2ra): Declaration prototype.
8434 * unif.c (scm_array_equal_p): Dummy definition removed (it is
8435 defined in ramap.c).
8437 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
8438 Redundant declarations removed (they are in ramap.h).
8440 * variable.h (scm_make_udvariable,
8441 scm_make_undefined_variable): Declaration corrected to
8442 correspond variable.c.
8444 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
8445 Missing declarations added.
8447 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
8449 * Makefile.in (distclean): Don't forget to delete fd.h.
8451 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
8453 * fd.h.in, tags.h: Trivial cleanups.
8455 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
8456 marksweep.h just declared functions from gc.c.
8457 * gc.h, libguile.h: Don't #include "marksweep.h".
8458 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
8459 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
8460 dependencies updated.
8462 * libguile.h: Don't #include "files.h"; it's been deleted.
8464 * files.c (scm_sys_delete_file): Moved to filesys.c.
8465 File is now empty; deleted.
8467 * filesys.c: scm_sys_delete_file is now here. Remove
8468 #if's; they seem to rely on remnants of an old portability
8469 regimen. If the problems come up again, solve them properly,
8470 using autoconf. Specifically: Don't test M_SYSV, and #define
8471 remove to be unlink if it's #defined; don't use remove just
8472 because HAVE_STDC_HEADERS is #defined.
8473 * filesys.h: Add declarations for scm_sys_delete_file.
8474 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
8475 files.o, files.h, files.c, and files.x.
8476 * init.c: Don't #include "files.h", and don't call scm_init_files.
8478 Use SCM_P instead of PROTO; the latter intrudes on the user's
8480 * params.h: Deleted; definition of SCM_P moved to...
8481 * __scm.h: ... here, where it replaces PROTO macro.
8482 * libguile.h, smob.h: Don't #include "params.h".
8483 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
8484 smob.h: Fix prototypes accordingly.
8485 * Makefile.in: Update dependencies.
8486 (inner_h_files): Remove params.h.
8488 * gc.c: #include "gc.h"; every module should include its header,
8489 to let the compiler cross-check the declarations against the
8492 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
8493 simpos.h: #include "libguile/__scm.h".
8495 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
8497 * init.c: Don't forget to #include smob.h and init.h.
8498 * Makefile.in: Dependencies updated.
8500 * smob.h: Use PROTO instead of #if __STDC__.
8502 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
8504 * __scm.h: Doc fixes.
8506 * __scm.h, libguile.h: Use "quotes" in the #includes, not
8507 <angles>; this allows `make depends' to work properly.
8509 * libguile.h: #include smob.h and pairs.h before the others; they
8510 define typedefs used by other headers.
8512 C files should #include only the header files they need, not
8513 libguile.h (which #includes all the header files); the pointless
8514 recompilation was wasting my time.
8515 * Makefile.in (all .o dependency lists): Regenerated.
8516 * libguile.h: Don't try to get a definition for size_t here...
8517 * __scm.h: Do it here.
8518 * _scm.h: Since this is the internal libguile header, put things
8519 here that all (or a majority) of the libguile files will want.
8520 Don't #include <libguile.h> here; that generates dependencies on
8521 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
8522 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
8523 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

8619 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
8620 * weaks.c: Get "weaks.h".
8622 * stackchk.h: #include "libguile/debug.h",
8624 * print.h, read.h: #include "options.h", since everyone who uses
8625 either of these files will need that.
8627 * smob.h: #include "ports.h", "genio.h", and "print.h", since
8628 anyone who uses this file will need them to define the smob
8629 printing functions. Also, get markers.h, since people will need
8630 to #define the mark functions.
8632 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
8633 * ports.h: ... to here.
8635 * ports.h (scm_port_table_size): Explicitly give type as 'int';
8636 don't rely on archaic C default type rules.
8638 * fports.h: #include "libguile/ports.h", since you need that in
8639 order to parse this.
8641 * genio.h: #include "libguile/print.h", because you need that to
8642 parse this; don't bother #including "ports.h", since print.h gets
8645 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
8647 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
8648 this; it's now a reference to an element of *scm_root.
8650 * debug.h: Don't #include "options.h"; the compiler won't be able
8651 to find that once the headers are installed; instead, #include
8652 "libguile/options.h".
8653 * gc.h: Same, with marksweep.h.
8654 * mbstrings.h: Same, with symbols.h.
8655 * scmhob.h: Same, with _scm.h.
8656 * smob.h: Same, with params.h.
8658 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
8659 C files; there's no need for this, and it forces recompilations
8662 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
8664 * error.c (scm_error): declare scm_error_callback.
8666 * error.h: prototype for scm_error_callback.
8668 * __scm.h: define lgh_error.
8669 (SCM_SYSERROR): redefine using lgh_error.
8671 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
8673 * error.c (scm_error): new procedure.
8675 * error.h: prototype for scm_error.
8677 * Makefile.in (install): install scmconfig.h from the current
8678 directory, not $(srcdir).
8680 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8682 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8683 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8684 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
8685 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
8686 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,

8689 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8690 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8691 vports.h, weaks.h: #include "libguile/__scm.h", not
8692 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
8693 dependencies are within libguile properly.
8695 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8697 * Makefile.in (.c.x): Simplify; there's no need to run this rule
8698 when scmconfig.h doesn't exist.
8700 * load.c (scm_sys_try_load): Correct spelling.
8702 * feature.c (scm_loc_features): Make this static.
8704 * Makefile.in (libpath.h): Omit trailing slash from path. We
8705 shouldn't require it of users, so why put it here?
8707 Move code to initialize and search %load-path from ice-9 to C
8708 code, so we can use the load-path to find the ice-9 boot code;
8709 this makes it easier to run Guile without installing it. See
8710 corresponding changes in guile/Makefile.in.
8711 * feature.c: Move stuff concerned with the load path to load.c.
8712 (scm_compiled_library_path): Deleted.
8713 Don't #include libpath.h here.
8714 * feature.h: Don't mention scm_compiled_library_path.
8715 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
8716 <sys/stat.h>, and <unistd.h> (if present).
8717 (R_OK): #define if the system hasn't deigned to.
8718 (scm_loc_load_path): New variable.
8719 (scm_init_load_path, scm_sys_search_load_path,
8720 scm_sys_try_load_path): New functions.
8721 (scm_init_load): Initialize scm_loc_load_path to point to the
8722 value cell of the Scheme %load-path variable.
8723 * load.h: Add declarations for scm_sys_search_load_path,
8724 scm_sys_try_load_path.
8725 * init.c: Call scm_init_load_path.
8726 * Makefile.in (feature.o, load.o): Dependencies updated.
8728 * load.c, load.h: Rewrite using PROTO macro.
8730 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8732 * gc.c (scm_cellp): New function: C predicate to determine if an
8733 SCM value can be regarded as a pointer to a cell on the heap.
8735 * gc.h: Added declaration of scm_cellp.
8737 * gdb_interface.h: New file: The GDB interface header from the GDB
8740 * gdbint.c: New file: GDB interface.
8742 * gdbint.h: New file: GDB interface.
8744 * libguile.h: Added #include <libguile/gdbint.h>.
8746 * init.c (scm_boot_guile): Added scm_init_gdbint.
8748 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
8749 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
8750 found if object files and source are kept separate).
8752 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
8754 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
8756 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
8758 * configure.in: Don't substitute the values of TCL_SRC_DIR and
8759 TK_SRC_DIR; they're not relevant any more.
8761 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
8762 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
8764 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
8766 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
8767 search path, so we can find the <libguile/MUMBLE.h> headers.
8769 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
8771 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
8772 implicit in the .c.o rule.
8773 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
8776 Put the library path in a header file, instead of passing it on
8777 the command line in every compilation.
8778 * Makefile.in (libpath.h): New target.
8779 (feature.o): Depend on libpath.h.
8780 (clean): Delete libpath.h.
8781 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
8782 * feature.c: ... #include "libpath.h" here.
8783 * .cvsignore: Ignore libpath.h.
8785 Don't install the unwashed masses of Guile header files in the
8786 main #include path; put most of them in a subdirectory called
8787 'libguile'. This avoids naming conflicts between Guile header
8788 files and system header files (of which there were a few).
8789 * Makefile.in (pkgincludedir): Deleted.
8790 (innerincludedir): New variable; this and $(includedir) are enough.
8791 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
8792 (installed_h_files): Divide this up. Now this variable lists
8793 those header files which should go into $(includedir) (i.e. appear
8794 directly in the #include path), and ...
8795 (inner_h_files): ... this new variable says which files appear in
8796 a subdirectory, and are referred to as <libguile/mumble.h>.
8797 (h_files): List them both.
8798 (install): Create innerincludedir, not pkgincludedir. Put
8799 the installed_h_files and inner_h_files in their proper places.
8800 (uninstall): Corresponding changes.
8801 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8802 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8803 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,

8809 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8810 vports.h, weaks.h: Find __scm.h in its new location.
8811 * __scm.h: Find scmconfig.h and tags.h in their new locations
8812 (they're both "inner" files).
8814 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
8816 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
8818 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
8820 * posix.c: Doc fixes.
8822 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
8824 * socket.c: Don't include a prototype for inet_aton; just use a
8825 K&R style declaration, to avoid warnings but minimize the chance
8826 of conflicts with the system.
8828 On NextStep, <utime.h> doesn't define struct utime, unless we
8829 #define _POSIX_SOURCE before #including it.
8830 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
8831 * acconfig.h: New comment text for above CPP symbol.
8832 * configure.in: Call it.
8833 * posix.c: #define _POSIX_SOURCE if it seems necessary.
8835 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
8837 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
8838 testing for __EMX__.
8840 * posix.c: #include <libc.h>, if it exists.
8842 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
8843 don't even know if the latter exists.
8845 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
8846 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
8847 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
8849 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
8851 (scm_init_posix): Use them when initializing the Scheme constants
8854 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
8856 * Makefile.in (libdir, includedir, bindir): Use the
8857 autoconf-supplied values, instead of deriving them ourselves.
8858 (pkgincludedir, datadir, pkgdatadir): New variables.
8859 (install, uninstall): Put the header files in a special
8860 subdirectory, not in the main search path.
8862 * Makefile.in (ALL_CFLAGS): Provide the proper value for
8863 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
8865 * Makefile.in (IMPLPATH): Deleted; never used.
8867 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
8868 on the Tcl/Tk source any more.
8869 (INCLUDE_CFLAGS): Remove references to the above.
8871 * Makefile.in (version.o): Corrected dependencies.
8873 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8875 * libguile.h: #include "version.h"
8877 * init.c (scm_boot_guile): Call scm_init_version.
8878 * gscm.c (gscm_run_scm): Call scm_init_version.
8880 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8881 GUILE_VERSION): AC_DEFINE these.
8882 (acconfig.h): #undef the above symbols.
8884 * Makefile.in (libobjs): Add version.o.
8885 (installed_h_files): Add version.h.
8886 (c_files): Add version.c.
8887 (gen_c_files): Add version.x.
8888 (version.o): New rule.
8889 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
8890 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
8891 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,

8898 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
8899 weaks.o): Add version.h to dependency lists.
8900 (markers.o): Remove duplicate rule.
8902 * version.h: New file.
8904 * version.c: New file.
8906 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8908 * symbols.c (scm_strhash): scm_downcase is now a function, not an
8909 array; use it appropriately. Since GCC is quite happy to
8910 subscript functions, it never warned us about this; we should use
8911 -Wpointer-arith in the future. I guess we never tested
8914 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
8916 * socket.c: Doc and copyright fixes.
8918 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8920 * debug.c: Fixed and improved gdb support.
8922 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8924 * socket.c: Added declaration of inet_aton to avoid compiler
8925 warning. (Hope this solution is correct.)
8927 * stime.c: Added declaration of ftime. (This is missing in
8930 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
8932 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8934 * Makefile.in (c_files): add strerror.c.
8936 * strerror.c: new file from Emacs' sysdep.c.
8937 maybe configure should also check for sys_errlist.
8939 * configure.in (AC_REPLACE_FUNCS): add strerror.
8941 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8943 * debug.c (scm_init_debug): Added initialization for
8944 scm_evaluator_traps.
8946 * debug.h, debug.c: Various name changes.
8947 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
8948 "debug-options-interface". See commentary in options.c.
8950 * options.h, options.c: Options now have documentation strings.
8951 Also added a long explanatory commentary.
8953 * eval.c, print.h, print.c, read.h, read.c: Modifications to
8956 * gscm.c, init.c, root.c, throw.c: Bug fixes:
8957 last_debug_info_frame is now updated in all cases.
8959 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
8962 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8964 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
8965 Added option STACK_CHECKING.
8967 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8969 * Makefile.in: Added {debug,options,srcprop}.{h,c}
8971 * __scm.h: Removed symbols for debugging support.
8973 * acconfig.h: Added symbols for debugging support.
8975 * configure.in: Added user option for debugging support.
8976 --enable-debug will include the debugging code into libguile.a.
8978 * continuations.c (scm_make_cont): Enlarged the #if 0 around
8979 scm_relocate_chunk_to_heap.
8981 * debug.c: New file: low-level debugging support. It also
8982 includes support for debugging with gdb. (The extensions to gdb
8983 are written by Per Bothner at Cygnus.)
8985 * debug.h: New file: low-level debugging support.
8987 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
8988 argument pairs. Extensive modifications to the debugging
8989 evaluator. Added "SECTION:" commentaries to clarify what happens
8990 when, during double compilation. Renamed EVALIMP --> EVALIM.
8991 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
8992 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
8993 the beginning of the file. New procedure: scm_unmemocopy.
8994 Added some global state variables needed by the debugging
8995 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
8996 check_entry, check_apply, check_exit, debug_options and
8997 evaluator_traps. New acro: undefine.
8999 * eval.h: Renamed EVAL --> XEVAL.
9001 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
9002 --> scm_make_weak_key_hash_table.
9004 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
9005 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
9007 * libguile.h: Conditionally include debug.h
9009 * objprop.c (scm_object_properties, scm_set_object_properties_x):
9010 scm_object_properties shouldn't return handle. `handle' now gets
9011 initialized in scm_set_object_properties_x. scm_object_properties
9012 doesn't any longer create an entry in scm_object_whash.
9014 * options.c: New file: handling of run time options.
9016 * options.h: New file: handling of run time options.
9018 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
9020 * print.c: New procedure: scm_print_options
9022 * print.h: Defines for print options.
9024 * read.c: New procedure: scm_read_options
9026 * read.h: Defines for reader options.
9028 * root.h: Added scm_source_whash among scm_sys_protects.
9030 * srcprop.c: New file: source properties.
9032 * srcprop.h: New file: source properties.
9034 * throw.c (jbsmob): Jump buffers are now correctly allocated.
9035 (Bug found by A. Green.)
9037 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
9039 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
9041 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
9043 * libguile.h: #include "objprop.h"; I guess this was forgotten.
9045 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
9046 and should be called by the final client.
9048 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
9050 * gc.h: Use the PROTO macro when declaring functions.
9051 * gc.c: Use the PROTO macro when declaring static functions.
9052 Remove the CPP hair around function definitions.
9054 * gc.c (scm_init_storage): Initialize scm_asyncs.
9056 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
9057 preprocessor symbol; "__scm.h" is where it might get #defined.
9058 * __scm.h: Similar: #include <scmconfig.h> before testing
9061 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
9063 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
9065 * init.c (scm_boot_guile): Add init_func argument; call
9066 (*init_func) instead of calling scm_appinit; it's ucky to
9067 hard-code names for the user's procedures.
9068 * init.h (scm_boot_guile): Adjust declaration.
9070 * __scm.h (PROTO): New macro, for declaring functions with
9073 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
9074 eliminate all the __STDC__ conditionals.
9075 (scm_boot_guile): Add declaration.
9076 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
9077 Remove __STDC__ conditionals around function definitions; the
9078 declarations in init.h will provide the same information, more
9081 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
9082 complain about it in the error message; the error message is
9083 adequate without that note, and there's nothing the user can do
9086 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
9088 * Makefile.in (ancillary): Drop def.sed.
9090 * posix.c (scm_init_posix): Use numeric values, rather than
9091 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
9092 F_OK. The symbols aren't available on some systems, and I'm
9093 pretty sure their values are fixed by common widespread practice.
9094 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
9096 More functions unavailable on some systems.
9097 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
9098 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
9100 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
9101 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
9102 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
9103 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
9104 stub that signals an error as the #else.
9106 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
9108 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
9110 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
9112 * unif.c: include ramap.h.
9114 * read.c (endif): case_insensative_p renamed case_insensitive_p.
9116 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
9118 * ports.c: include sys/ioctl.h.
9120 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
9122 * configure.in: check for sys/ioctl.h.
9124 * ports.c: include <malloc.h> not "malloc.h".
9126 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
9128 * fports.c: remove ttyname and tmpnam declarations.
9130 * posix.c: fewer ttyname declarations.
9132 * fports.c: include <string.h> not "string.h".
9134 * init.c, ioext.c: include string.h and unistd.h.
9136 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
9138 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
9139 genio.c, simpos.c, vports.c: include string.h.
9141 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
9143 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
9145 (scm_addr_buffer_size): change type from scm_sizet to int.
9146 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
9147 from scm_sizet to int.
9149 * error.c: include unistd.h.
9151 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
9154 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
9156 * __scm.hd, def.sed: deleted.
9158 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
9160 Changes for NeXT, suggested by Robert Brown.
9161 * configure.in: Call AC_TYPE_MODE_T.
9162 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
9163 NeXT. Put header file list in alphabetical order.
9164 * configure, scmconfig.h.in: Regenerated.
9165 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
9167 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
9170 * acconfig.h: New file, providing documentation for the CPP
9171 symbols defined in configure.in
9172 * acconfig-1.5.h: Removed; superceded by the above.
9174 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
9176 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
9178 * fports.c (scm_open_file): don't return #f, throw error.
9180 * ioext.c (fileno): renamed from %fileno.
9181 (soft-fileno): deleted.
9183 * ports.c (scm_port_revealed): don't need to check for -1 from
9185 (scm_set_port_revealed_x): return unspecified, not #f.
9187 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
9189 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
9191 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
9193 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
9195 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
9197 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
9198 This is necessary on Ultrix, and doesn't hurt portability.
9200 * Makefile.in (dist-dir): New target, implementing a new dist system.
9201 (installed_h_files): Put in alphabetical order.
9202 Remove duplicate entries for markers.h and unif.h.
9203 (c_files): Remove duplicate entries for markers.c.
9204 (ancillary): Renamed from anillery; all uses changed. Remove
9205 PLUGIN; it's a directory, and needs special treatment in dist-dir.
9206 Remove all the ../doc/* files; doc/Makefile.in handles that.
9208 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
9210 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
9211 every if must have an else, or else the whole command has a
9212 non-zero exit code whenever the if's condition is false.
9214 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
9216 * posix.c: include string.h.
9218 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
9220 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
9223 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
9224 Remove leading % from scheme names.
9225 Do not return error values, call SCM_SYSERROR or similar.
9227 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
9229 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
9231 * struct.c (scm_init_struct): new file.
9233 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
9235 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
9236 (scm_list_head): added list-head for rapidly chopping argument
9237 lists off of longer lists (and similar).
9239 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
9241 * objprop.c (scm_object_property): assq the cdr of the whash
9242 handle for obj, not the handle itself.
9244 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
9246 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
9247 weak hash tables last of all marking to avoid an obscure gc bug.
9248 WARNING: circular lists stored in a weak hash table will hose us.
9250 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
9252 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
9253 new functions similar to scm_substring_move_left_x and
9254 scm_substring_move_right_x.
9256 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
9258 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
9261 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
9263 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
9265 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
9267 * strports.c (scm_strprint_obj): convenience function. C for
9268 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
9270 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
9271 removed to a separate library
9273 * init.c (scm_boot_guile): copied from guile-tcl.c.
9274 Initialization specific to tcl interpreters removed.
9276 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
9278 * ports.c (scm_ports_prehistory): size malloced here doesn't
9279 matter so long as it is non-0 (got rid of "* 4").
9281 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
9283 * gscm.h: gscm_mkarray eliminated (presumably was not being used
9284 since its definition was bogus).
9286 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
9288 * mallocs.[ch]: back again (for rx at least).
9290 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
9292 * ports.c: removed functions relating to the mapping between ports
9293 and descriptors. (That stuff is unix-specific and should be collected
9294 in a separate library).
9296 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
9297 (Tom Mckay@avanticorp.com)
9299 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
9301 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
9302 handled correctly (SCM_FREEP was applied to them) -- test for
9303 NIMP. Keys in weak hash tables were spuriously (though harmlessly)

9471 initialization to fix a race condition.
9473 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
