1 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
3 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
5 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
7 * acconfig.h: Added entry for PACKAGE.
8 * scmconfig.h.in: Regenerated.
10 Changes to work with automake-1.1n, which has better libtool support.
11 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
12 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
14 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
16 * Makefile.in: Rebuild.
18 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
20 * stime.c (scm_init_stime): don't define ticks/sec.
21 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
22 return value problem and is still portable.)
24 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
26 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
27 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
28 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
29 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
30 cpp_err_symbols.c): Corresponding changes.
31 * Makefile.in: Regenerated.
33 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
35 * posix.c (scm_putenv): don't check HAVE_PUTENV.
36 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
37 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
38 * putenv.c: new file, from sh-utils 1.12.
40 * posix.c (scm_environ): use malloc in place of scm_must_malloc
41 since allocation isn't for Scheme objects.
42 (scm_putenv): copy strings before placing in the environment.
44 * stime.c (scm_current_time): throw an error if time returns -1,
45 instead of returning #f.
46 (scm_get_internal_real_time, scm_get_internal_real_time): use
47 scm_long2num for return value instead of SCM_MAKINUM.
49 * stime.h: prototypes updated.
51 * stime.c (scm_time_in_msec): apparently unused, deleted.
53 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
55 * configure.in: check for gettimeofday.
57 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
58 which may be more usefully portable than a gettimeofday interface.
60 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
62 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
64 * Makefile.in: Regenerated.
66 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
68 * stime.c (filltime): recovered static procedure.
69 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
72 * posix.h: add prototype for scm_close_pipe, remove prototypes for
73 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
75 * * posix.c (scm_mknod): split the mode argument into type and perms
76 arguments, like the extra fields returned by stat.
78 * fports.c (scm_pipob): set the close, free and print procedures.
79 (scm_close_pipe): new procedure.
81 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
82 define them in boot-9.scm
84 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
86 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
87 wan't defined. Don't include fd.h.
89 * Previously fd.h was regenerated whenever configure was run,
90 forcing a couple of files to be recompiled.
92 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
93 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
94 Check for _fileno as well as _file.
96 * ioext.c: don't fd.h.
97 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
100 * Change the stratigy for getting information about errno
101 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
102 generating lists of symbols during the build process, which will
103 not always work, include comprehensive lists in the distribution.
104 To help keep the lists up to date, the "check_signals" and
105 "check_errnos" make targets can be used.
107 * configure.in: don't check for a command to extract errno codes.
108 * Makefile.am: update file lists, remove errnos.list and errnos.c
109 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
110 check_errnos targets.
111 (CLEANFILES): remove errnos.c and errnos.list, add
112 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
113 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
114 * errnos.default: deleted.
115 * cpp_signal.c: new file.
116 * cpp_errno.c: renamed from errnos_get.c.
117 * cpp_err_symbols, cpp_sig_symbols: new files.
118 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
119 * error.c (scm_init_error): #include cpp_err_symbols instead of
121 * posix.c (scm_init_posix): don't intern signal symbols. #include
124 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
126 * strop.c (scm_i_index): allow the lower bound to be equal to the
127 length of the string, so a null string doesn't always give an error.
129 * posix.h: new prototypes.
130 * posix.c (scm_status_exit_val, scm_status_term_sig,
131 scm_status_stop_sig): new functions, as in scsh. They break down
132 process status values as returned by waitpid.
134 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
136 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
137 configure doesn't know about it.
139 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
141 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
143 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
144 which defines C variables with global linkage.
146 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
148 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
151 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
153 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
154 has time to check why this doesn't work well with continuations.
156 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
158 * Fix shell syntax error; some shells won't tolerate
159 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
161 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
163 * posix.c (scm_uname): throw an error if uname fails instead
166 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
168 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
171 * async.c (scm_ints_disabled): definition moved from error.c.
173 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
175 * acconfig.h: Removed PACKAGE.
177 * scmconfig.h.in: Regenerated.
179 * snarf.h: g++ says it's non-portable not to specify the first
180 argument in a varargs declaration. I introduced the first
181 argument by using preprocessor conditionals.
183 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
185 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
186 (scm_freopen): use RO string macros for filename and modes.
187 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
189 * posix.c (scm_getgrgid): simplify conversion of name to C string.
190 (scm_mknod): use RO string macros for path.
192 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
193 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
195 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
196 use SCM_ROSTRINGP and SCM_ROCHARS.
198 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
200 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
203 * ramap.c (scm_ra_matchp, scm_ra_matchp, scm_array_fill_int, racp,
204 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
205 support for byte vectors.
207 * print.c (scm_iprin1): Limit number of vector elements printed
208 according to pstate->length.
210 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
212 * backtrace.c (scm_display_error_message): don't segv if message
215 * error.h: prototype for scm_error_scm.
217 * error.c (scm_error_scm): new procedure, reimplements scm-error
218 in C and uses scm_error.
220 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
222 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
223 pointer to the Scheme variable read-hash-procedures and intern it
224 in scm_init_read. Modify scm_read_hash_extend and
225 scm_get_hash_procedure to use the pointer.
227 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
229 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
230 (SCM_KEYWORD_STYLE): defined.
232 * read.c (scm_read_opts): add a keywords option. This isn't a
233 boolean option, in case someone wants to add support for DSSSL
235 Setup scm_keyword_prefix symbol.
236 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
238 * I've left keyword support disabled by default, since it doesn't
239 seem to break the module system and it gives R4RS standard behaviour.
240 It can be reactivated with (read-set! keywords 'prefix).
242 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
244 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
245 before constructing arbiter.
247 * eval.c (scm_m_define): Bugfix: Check that the object is a
248 closure before setting the procedure property!
250 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
252 * ports.c: Removed `ungetc-char-ready?'.
254 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
256 * read.c (scm_init_read): intitialise scm_read_hash_procedures
257 (idea from Mikael: make it a pair so scm_permanent object only
259 (scm_read_hash_extend): don't call scm_permanent_object.
260 (ideas from Mikael): if chr is already in the list, replace its
261 procedure instead of appending it again. If proc is #f, remove
263 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
265 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
267 * gdbint.c (gdb_read): update scm_lreadr usage.
269 * load.h: update prototypes.
271 * load.c (scm_primitive_load, scm_read_and_eval_x,
272 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
274 * read.h: add prototype for scm_read_hash_extend. Change args for
277 * read.c (scm_read_hash_procedures): new variable.
278 (scm_read_hash_extend): new procedure.
279 (scm_get_hash_procedure): new procedure.
280 * (scm_lreadr): use scm_get_hash_procedure instead of an argument
281 for extended # processing.
282 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
283 scm_read_token): remove case_i, sharp arguments. Change callers.
285 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
287 * read.h (SCM_N_READ_OPTIONS): increase to 3.
288 (SCM_CASE_INSENSITIVE_P): define.
290 * read.c: add case-insensitive option to scm_read_opts.
291 * (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
292 to determine whether to convert symbol case.
293 (default_case_i): definition removed.
294 * read.c (scm_read_token): if case_i, downcase ic before doing
297 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
299 * configure.in: Added configuration option `guile-debug'.
300 Configure with --enable-guile-debug if you want a bunch of extra
301 functions used for debugging when developing Guile.
303 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
305 * procs.c (make-cclo): New undocumented debugging procedure: Make
306 compiled closure with internal procedure PROC and length LENGTH.
307 Only compiled if GUILE_DEBUG is defined.
309 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
311 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
313 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
315 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
316 with 3 or more args internally to the evaluator.
318 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
320 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
321 with 3 or more args internally to the evaluator. This is mainly
322 because we don't want to pass entry and exit points of the
323 debug support twice, but it also seems to increase the speed of
324 the evaluator for such calls (e. g. (+ 1 2 3)).
326 * * backtrace.c (scm_display_application): New procedure:
327 display-application; Set fancy printing parameters individually
328 for different types of display (backtrace, error, application).
329 (These should of course be customizable!)
331 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
332 clear the CHECK-flags.
334 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
336 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
338 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
340 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
341 from pairs with a GLOC in the car.
343 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
344 otherwise `symbol-hash' will behave badly.
345 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
346 we get segmentation fault!
348 * * symbols.c: Added #include "weaks.h". New functions:
349 `builtin-bindings' and `builtin-weak-bindings'. (These will be
350 moved to an extraneous library when we split libguile.)
352 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
354 * filesys.c (scm_stat): stat now takes fport arguments too as
355 documented in the manual.
357 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
359 * debug.c (scm_single_step): Bugfix: Call continuation with
360 scm_call_continuation instead of throwing to it.
362 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
364 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
365 argument wasn't declared to be optional.
367 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
369 * stime.c (scm_init_stime): Add feature "current-time".
371 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
373 * throw.h: prototype for scm_exit_status.
374 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
375 args to derive an exit status. Allows (quit) to work from a
377 (scm_exit_status): new function.
380 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
382 * eval.c (scm_deval): Removed some old code.
383 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
385 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
388 * symbols.c (msymbolize): Bugfix: Must initialize property list to
391 * procs.c: Introduce the existent C function scm_thunk_p at the
392 Scheme level as well.
394 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
396 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
397 used from C to easily lookup the value of a symbol in the current
400 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
402 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
403 scm_init_unif in this file. This will also fix a previous problem
406 * configure.in: Added AM_MAINTAINER_MODE
408 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
410 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
413 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
415 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
416 source files that are not always included in libguile but should
417 have their dependencies calculated by automake. This variable is
418 recognized by automake, no further magic is needed.
419 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
420 to deal exclusively with *.lo files, as it seems. The *.o files
421 are built automatically when the corresponding *.lo file gets
424 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
426 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
429 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
431 * unif.c (scm_array_set_x): minor change to argument error checking.
433 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
435 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
436 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
437 They should only be included in the library at configure.in's
439 (libguile_la_LDADD): Include the appropriate .lo files here.
440 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
441 so we know when to build them (and their .lo bretheren).
442 * configure.in (LIBLOBJS): New substituted variable. We let
443 configure decide which .o files to include in LIBOBJS, and then
444 put the corresponding list of .lo files in LIBLOBJS. The latter
445 is what we pass to libtool.
446 * Makefile.in, configure: regenerated.
448 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
450 * symbols.c (scm_sysintern0): New function. Contains the core of
451 old scm_sysintern but doesn't take a second value argument.
452 (scm_sysintern): Now uses scm_sysintern0.
453 (scm_sysintern_no_module_lookup): Renamed to
454 scm_sysintern0_no_module_lookup and doesn't take a second value
457 * symbols.h (scm_sysintern0: Added declaration.
459 * options.c (scm_init_opts): Use scm_sysintern0 instead of
460 scm_sysintern when interning option keys. Otherwise we risk
461 destroying the values of already interned variables.
463 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
464 scheme-level boolean (use SCM_NFALSEP).
466 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
468 (scm_backtrace): New function. (C version of old function from
469 boot-9.scm) Motivation: Make it possible to display backtraces
470 without depending on boot-9.scm. (I'm uncertain if this
471 motivation is good enough...)
473 * root.h (scm_root_state): Add member the_last_stack_var.
474 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
476 * root.c (mark_root): Mark scm_the_last_stack_var.
478 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
481 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
483 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
484 1. mark_lazy_catch didn't mark the smob.
485 2. Both functions above have standard variants:
486 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
487 free_lazy_catch --> scm_free0.
489 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
491 * throw.c (scm_internal_lazy_catch): New function.
492 (scm_lazy_catch): Rewritten to use it.
493 (scm_ithrow): Handle the new lazy catch representation.
494 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
495 that doesn't have a jmpbuf is a lazy catch clause.
496 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
497 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
498 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
500 (scm_init_throw): Register the new lazy-catch smob type.
501 * throw.h (scm_internal_lazy_catch): decl for new function.
503 * throw.c (scm_internal_catch): Doc fixes.
505 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
506 configure.in. Including this might cause problems if applications
507 that link against libguile include their own copies of alloca, but
508 if they're using autoconf, they should be adding libguile to LIBS
509 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
510 the copy in libguile, and things will be okay. (I think.)
512 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
514 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
516 strop.h: move prototypes too.
518 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
520 * posix.c (scm_init_posix): don't intern EINTR since it's now done
523 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
524 etc. I deleted them from filesys.c long ago, but didn't
525 notice they were here too (although ineffective since
526 sys/stat.h wasn't included).
528 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
530 * eval.c: Don't define alloca in GCC case. gcc will automatically
531 use __builtin_alloca if appropriate.
533 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
535 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
536 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
537 that values of automatic variables are preserved. See comments
538 for safe_setjmp for details.
540 Change from Thomas Morgan:
541 * variable.c: Include eq.h.
542 (var_equal): New function.
543 (variable_smob): Use var_equal as the discriminator for variables.
545 * throw.c (s_throw): Remove extraneous declaration.
547 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
548 * eval.c: Add necessary CPP cruft to support that.
549 * configure, Makefile.in, scmconfig.h.in: regenerated.
551 Change from Thomas Morgan:
552 * procprop.c (scm_procedure_properties): Convert the Scheme
553 boolean returned by scm_procedure_p into a C boolean before using
554 it as a condition for SCM_ASSERT.
555 (scm_procedure_property): Likewise.
557 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
558 indications of Unixness.
561 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
563 * * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
565 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
567 * read.c (scm_lreadr): use scm_misc_error to improve one of the
568 "unknown # object" error messages.
570 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
571 (scm_i_index) and declare it static. Add a 'direction' argument
572 to indicate what way the search should go.
573 (scm_i_index): throw out-of-range error instead of wrong-type-arg
575 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
576 strop.h: remove scm_i_index, scm_i_rindex prototypes.
578 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
580 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
582 * * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
583 to avoid clash with various scsh forks.
585 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
587 The following two changes (ramap.c, throw.c) are motivated by the
588 apparent unportability of forward declarations of static arrays of
589 the form `static foo bar[];'.
591 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
592 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
594 * throw.c (scm_throw): Moved above scm_ithrow.
596 * options.h: Removed the extern declarations of scm_yes_sym and
597 scm_no_sym since these are static.
599 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
601 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
603 * Makefile.am: remove AWK=@AWK@.
604 Add a rule for generating errnos.list.
605 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
607 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
608 don't extract errnos, just set a variable (avoids the
609 need to recompile error.c just because configure is run.)
611 * unif.h: update prototypes.
612 * unif.c (scm_uniform_array_read,write): change the offset and
613 length arguments to start and end, for consistency.
615 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
617 * ioext.h: update prototypes.
618 * * ioext.c (scm_read_delimited_x): replaces scm_read_line and
619 scm_read_line_x, it's a more general procedure using an
620 interface from scsh. read-line and read-line! are now defined
622 * Note that the new read-line trims the terminator
623 by default, previously it was appended to the returned string. An
624 optional argument specifies how to process the terminator (scsh
625 compatible). For the old behaviour: (read-line port 'concat).
626 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
627 returns a pair, but is converted to multiple values if the scsh
630 socket.h: update prototypes.
631 * socket.c (scm_recvfrom): for consistency with other procedures,
632 take start and end as separate optional arguments.
633 * (scm_recv, scm_recvfrom): don't allow the second argument
634 to be a size, only a buffer. Change the scheme names to
635 recv! and recvfrom!. Don't return the buffer.
637 * ioext.h, posix.h: move prototypes too.
638 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
639 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
640 "read.h" and "unif.h".
641 * ioext.c: include "chars.h"
643 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
645 * dynl.c: The dynamic linking and module registration functions
646 are now defined even when dynamic linking is not available for the
647 host system. Some of their functionality can be done without
648 dynamic linking; when it's really needed, they throw errors.
650 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
652 * configure.in: Only define DYNAMIC_LINKING when one of the system
653 dependent functions is detected.
654 * dynl.c (scm_dynamic_func): New function to get the address of a
655 function in a dynamic object.
656 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
657 produced by scm_dynamic_func as the thing to call.
659 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
661 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
662 (scm_register_module_xxx, scm_registered_modules,
663 scm_clear_registered_modules): New functions.
665 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
667 * symbols.c (scm_sysintern): Renamed to
668 scm_sysintern_no_module_lookup.
669 (scm_sysintern): New function to take the place of the old
670 scm_sysintern. It uses the current toplevel lookup closure to give
671 the symbol its value. This is a temporary hack to put packages
672 like gtcltk into their own module.
673 (scm_can_use_top_level_lookup_closure_var): New variable to tell
674 us whether `scm_top_level_lookup_closure_var' has been initialized
676 * eval.c (scm_init_eval): Set it.
678 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
680 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
681 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
683 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
685 * (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
686 scm_sys_dup): deleted: FD capability will be added to other
688 * Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
689 scm_fd_free, fd_smob, scm_intern_fd.
690 * (scm_open): renamed from scm_sys_open. Return a port instead of
691 an FD object. Make the mode argument optional.
692 * (scm_sys_create): deleted, it's just a special case of open.
693 (scm_init_filesys): move interning of constants O_CREAT etc.,
694 here (were previously using SCM_CONST_LONG macro).
695 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
697 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
698 include "fports.h" and <stdio.h>
699 (scm_stat, scm_select): don't support FD objects.
701 * error.h: adjust scm_syserror_msg prototype.
702 * error.c (scm_syserror_msg): take an extra argument for errno.
703 Using the global value didn't always work, since it could be
704 reset by procedure calls in the message or args arguments.
706 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
707 I don't understand why the check was there (and what about the
710 * strop.c (scm_string_copy): allow shared substrings to be copied.
712 * unif.h: corresponding change to prototypes.
713 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
714 recognize two new optional arguments: offset and length. Allow
715 the port argument to be an integer (file descriptor, for scsh).
716 Include <unistd.h> for "read" prototype.
718 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
720 * socket.c: don't include filesys.h.
722 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
724 * Makefile.am: add AWK=@AWK@ (?)
726 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
728 Add a rule to generate errnos.c from errnos.
729 * error.c (scm_init_error): include errnos.c.
730 * errnos_cnvt.awk: new file, converts the list of errno codes to
732 * errnos_get.c: new file.
733 * errnos.default: new file, contains errnos to try if they can't
734 be extracted from errno.h.
735 * configure.in: if using GCC, try and extract errno codes from
739 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
741 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
742 * Makefile.am: Made libguile into a libtool library.
743 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
744 Set libtool_libs to indicate that libguile is a libtool library.
745 See guile/ChangeLog for details.
746 * .cvsignore: ignore "*.lo", the libtool library objects.
748 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
750 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
751 use htons in getservbyport argument.
753 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
755 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
756 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
759 * objprop.c (scm_object_property): No need to take the CDR of the
760 value returned by scm_object_properties, since Aug 20 change.
762 * configure.in: When checking for struct linger, #include
763 <sys/types.h> as well as <sys/socket.h>. I've never known
764 <sys/types.h> to cause any portability problems, and Solaris's
765 <sys/socket.h> needs it.
766 * configure: Rebuilt.
768 I think the Sun compiler has chosen a perverse way to interpret
769 ANSI declarations combined with K&R definitions. We'll
770 appease it a little bit. But when it invades France, we fight.
771 * print.c (scm_iprlist): Change 'tlr' argument to an int.
772 * print.h (scm_iprlist): Here too.
773 * numbers.c (scm_divbigdig): Change definition to match
774 declaration in numbers.h.
775 * unif.c (scm_makflo): Change definition to match declaration in
778 * init.c (scm_boot_guile): Don't return the value of
779 scm_boot_guile_1. This function doesn't return a value;
780 scm_boot_guile_1 doesn't return a value (or return at all).
782 * eval.c (unmemocopy): Add a semicolon to appease the Sun
785 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
786 compile. I have a feeling this function is a bad idea anyway ---
787 one should always test for features, not systems.
789 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
790 semicolons. Only pure luck kept this from being noticed earlier.
792 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
794 * socket.c (scm_recvfrom): Added missing semicolon.
796 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
798 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
799 the buffer and start and end positions for scsh networking
802 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
804 * configure.in: Revert previous change to this file; the problem
805 is due to transient automake weirdness.
806 * configure: Rebuilt.
808 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
809 PLUGIN/guile.libs. configure generates the latter from the former.
810 * Makefile.in: Rebuilt.
812 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
813 need this if we install scripts, like guile-snarf.
814 * configure: Rebuilt.
816 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
818 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
820 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
822 * socket.c (scm_addr_vector): fix faulty scm_listify.
824 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
826 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
827 style block comment is no longer considered an error.
829 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
831 * PLUGIN/guile.libs.in: New file.
832 * PLUGIN/guile.libs: Removed from repository.
833 * configure.in: Create PLUGIN/guile.libs from
834 PLUGIN/guile.libs.in. This is for including additonal libraries
835 needed for dynamic linking.
836 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
837 instead of PLUGIN/guile.libs.
839 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
841 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
843 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
844 occurrences of the given element from the list, not just the
845 first. This is how the Emacs Lisp functions behave, how the
846 analogous Common Lisp functions behave, and (I believe) how the
847 older Maclisp functions worked. I realize that this change may
848 break code, but it seemed better to break it before the Guile
851 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
852 Their prototypes were already present in gc.h, but they weren't
854 (scm_init_storage): Initialize scm_protects.
855 * root.c (scm_protects): New element of scm_sys_protects.
857 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
859 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
861 * libguile.h: Added #include "libguile/net_db.h".
863 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
864 30 change. That file is only meant for communication between the
865 configuration process and load.c. If code linked against libguile
866 wants to get at the paths mentioned in libpath.h, it can call
867 functions declared in load.h.
869 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
871 * libguile.h: Removed #include "libguile/fdsocket.h"
873 * net_db.c: Added #include <sys/socket.h>.
875 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
877 * filesys.c (scm_input_waiting_p): use select in preference to
878 FIONREAD, since the latter doesn't detect EOF.
879 Throw error if neither select nor FIONREAD available.
881 * socket.c (scm_connect): take a port, not a fd object.
882 (scm_fill_sockaddr): throw an error if fam is not recognised.
883 (scm_bind): use scm_fill_sockaddr.
884 (scm_listen): take a port, not a fd object.
885 (scm_accept): take and return a port. return #f in the car if
887 (scm_sock_fd_to_port): new procedure.
888 (scm_socket): use scm_sock_fd_to_port.
889 (scm_addr_vector): throw error if unrecognised address type.
890 take an extra argument with the calling procedure name.
891 (scm_getsockname): take a port. return #f if address can't be got.
892 (scm_getpeername): take a port. return #f if address can't be got.
893 (scm_recvfrom): take a port. return #f for address component if can't
895 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
896 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
898 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
900 * throw.c (scm_internal_catch): Make body funcs and handler funcs
901 use separate data pointers, to allow them to be designed
902 independently and reused.
903 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
904 Renamed from catch_body, catch_handler, and uncaught_throw; made
906 (struct scm_catch_body_data): Renamed from catch_body_data; moved
908 (scm_catch): Use the above.
909 (scm_throw): Don't bother printing a message for an uncaught
910 throw; we establish a default handler in init.
911 * throw.h (scm_internal_catch): Prototype updated.
912 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
914 (struct scm_body_thunk_data): New structure, used as data
915 argument to scm_body_thunk.
916 * init.c (struct main_func_closure): New structure, packaging up
917 the data to pass to the user's main function.
918 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
919 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
920 scm_internal_catch to establish a catch-all handler, using
921 scm_handle_by_message. This replaces the special-case code in
923 (invoke_main_func): Body function for scm_internal_catch; invoke
924 the user's main function, using the main_func_closure pointer to
925 decide what to pass it.
926 * root.c (struct cwdr_body_data): Remove handler_proc member.
927 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
928 (cwdr_handler): Removed.
930 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
932 * socket.h (SCM_P): update bind prototype.
933 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
935 (scm_socket): return a port, not a file descriptor object.
936 include "fports.h" and <unistd.h>
937 (scm_bind): take a port, not a file descriptor object.
938 take an extra argument for address args.
940 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
941 INADDR_NONE, INADDR_LOOPBACK.
943 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
945 * init.c: include net_db.h and not fdsocket.h.
946 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
948 * Makefile.am: corresponding changes.
949 * socket.h: renamed from fdsocket.h, fix names.
950 * net_db.h: renamed from socket.h, fix names.
951 * socket.c: renamed from fdsocket.c.
952 remove _sys from procedure names.
953 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
954 add "socket" to features list.
955 * net_db.c: renamed from socket.c.
956 remove _sys from procedure names.
957 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
958 add "net-db" to features list.
959 include "net_db.h". don't include <sys/socket.h> or
962 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
964 * tags.h (scm_tags): Removed comma at end of last enumerator.
966 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
968 Don't use GCC extensions to allocate space for debugging frames.
969 (Here he goes again! Why do we put up with this?!)
970 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
971 an scm_debug_info structure, not an in-line array of them. Add
972 'info' member, to say how many vect elements we've used, for eval
974 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
975 a new variable debug_info_end to mark the end of vect, instead of
976 the address of the 'info' pointer itself.
977 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
978 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
979 (SCM_APPLY): Explicitly allocate space for debug.vect.
980 * debug.c (scm_m_start_stack): Same, for vframe.vect.
981 * stacks.c: Adjusted for new debug frame structure.
982 (RELOC_INFO, RELOC_FRAME): New macros.
983 (stack_depth, read_frames): Use them, and new scm_debug_frame
984 element 'info', instead of magically knowing that eval frames have
985 an info pointer sitting after vect.
986 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
988 (scm_init_stacks): Formatting tweaks.
990 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
992 Give GCC more control flow information, so it can be sure that
993 variables aren't used uninitialized.
994 * error.h (scm_error, scm_syserror, scm_syserror_msg,
995 scm_sysmissing, scm_num_overflow, scm_out_of_range,
996 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
997 scm_misc_error): Tell GCC that these functions never return.
998 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
999 out the field type, call abort if SCM_ASSERT returns, to placate
1001 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
1002 scm_wta ever returns. We can't handle this case anyway, and this
1003 gives the optimizer more information.
1004 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
1005 scm_wta ever returns.
1007 In some cases, the code is fine, but GCC isn't smart enough to
1008 figure that out; this usually happens when one variable is only
1009 initialized and used when a particular condition holds true, and
1010 we know that condition will never change within a given invocation
1011 of the function. In this case, we simply initialize the variables
1012 to placate the compiler, hopefully to a value which will cause a
1013 crash if it is ever actually used.
1014 * print.c (scm_iprin1): Initialize mw_pos.
1015 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
1016 * throw.c (scm_ithrow): Initialize dynpair.
1017 * unif.c (scm_uniform_vector_ref): Initialize cra.
1018 * struct.c (init_struct): Initialize prot.
1019 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
1021 * strports.c (scm_eval_0str): Don't return uninitialized garbage
1022 if EXPR contains no expressions.
1024 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
1026 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
1027 cause an infinite loop (???). So much for the algebraic
1028 equivalency of variable-sized arrays and alloca...
1030 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
1032 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
1033 a SCM boolean, not a C boolean.
1035 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
1037 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
1038 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
1039 rules for raising scm_mtrigger. Previously, unfortunate but not
1040 unlikely circumstances could result in almost constant invokation
1041 of the gc. Now, this situations should be less likely, but they
1042 are not prevented completely.
1044 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
1046 * numbers.c (scm_fuck): Procedure removed; looks like old test
1048 * numbers.h: Prototype removed.
1050 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
1052 * debug.h (scm_debug_frame): Change `vect' member from an in-line
1053 array to a pointer, to match my Nov 21 change in eval.c.
1055 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1057 * libguile.h: Added #include "libguile/backtrace.h", #include
1058 "libguile/stacks.h".
1060 * strings.c (scm_string scm_make_string scm_string_ref
1061 scm_string_set_x scm_string_equal_p scm_string_append):
1062 Bugfix according to scm patch from Aubrey Jaffer:
1063 Corrected long-standing
1064 (not (eqv? (integer->char 128)
1065 (string-ref (make-string 1 (integer->char 128)) 0)))
1066 bug found by John Kozak <jk@noontide.demon.co.uk>.
1068 * strports.c, strports.h: Make scm_eval_0str return the value of
1069 the last expression evaluated (previously, it returned void).
1071 * strports.c, strports.h: New function: scm_read_0str. Does what
1074 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1076 * simpos.c (scm_getenv): return #f if string can't be found in the
1077 environment instead of throwing an exception, for compatibility
1078 with numerous other systems.
1080 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
1082 * Makefile.am (.c.x): Use guile-snarf.
1083 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
1085 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
1087 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1089 * backtrace.c (scm_display_error_message): Made non-static, and
1090 renamed from display_error_message.
1091 * backtrace.h (scm_display_error_message): Added extern decl.
1092 * throw.c (uncaught_throw): Use it to display the error message.
1094 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
1096 * inet_aton.c: Use #if 0, not #ifdef 0.
1098 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
1100 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
1101 to convert the returned value.
1102 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
1103 the offset argument.
1105 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1107 Add new interface to catch/throw, usable from C as well as
1109 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
1110 (scm_internal_catch): New function, replaces...
1111 (scm_catch_apply): Deleted.
1112 * throw.c (scm_catch_apply): Deleted; replaced with a more general
1113 mechanism which is a bit more code, but can be used nicely from C
1114 and implement the Scheme semantics as well.
1115 (scm_internal_catch): This is the replacement; it's named after
1116 the analogous function in Emacs.
1117 (scm_catch): Reimplemented in terms of the above.
1118 (struct catch_body_data, catch_body, catch_handler): New
1119 functions, used by scm_catch.
1120 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
1121 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
1122 support for new cwdr.
1124 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
1127 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
1129 * acconfig.h: Added DYNAMIC_LINKING symbol.
1130 * configure.in: Add option and checks for dynamic linking.
1131 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
1132 dynl.h: New files for dynamic linking support.
1133 * Makefile.am (libguile_a_SOURCES):
1135 (modinclude_HEADERS): Added "dynl.h".
1136 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
1138 * init.c (scm_boot_guile_1): Call
1139 scm_init_dynamic_linking to initialize dynamic linking support.
1141 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
1143 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
1144 (as we Schemers say). It needs to be global, so that I can tweak
1145 it for the proper operation of unexec.
1146 (scm_boot_guile_1_live): New variable, see above.
1148 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
1150 * guile-snarf.sh: Removed.
1151 * PLUGIN/guile.libs: Added dependency for -lm.
1152 * acinclude.m4: Renamed from aclocal.m4.
1153 * PLUGIN/greet: Removed.
1154 * Makefile.am, aclocal.m4: New files.
1155 * configure.in: Updated for Automake.
1157 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
1159 * eval.c (scm_definedp): Use top_level_lookup_closure_var
1160 and not top_level_lookup_thunk_var.
1162 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
1164 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
1166 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
1168 * eval.c (scm_definedp): Incompatibly changed to be a builtin
1169 Scheme function, instead of syntax. Single argument is now a
1172 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1174 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
1175 scm_ra_divide): Properly terminate statements passed as arguments
1176 to IVDEP macros. (Thanks to Bernard Urban.)
1178 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
1179 with non-constant sizes. (Thanks to Bernard Urban.)
1181 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1183 It's an "eval closure", not an "eval thunk." A thunk is a
1184 function of no arguments.
1185 * root.h (struct scm_root_state): Renamed
1186 top_level_lookup_closure_var from top_level_lookup_thunk_var.
1187 (scm_top_level_lookup_closure_var): Renamed from
1188 scm_top_level_lookup_thunk_var.
1189 * root.c (mark_root): Uses changed.
1190 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
1191 * init.c (scm_start_stack): Uses changed.
1192 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
1193 Change scheme-visible name to *top-level-lookup-closure* from
1194 *top-level-lookup-thunk*.
1196 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
1198 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
1199 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
1201 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
1203 * gc.c (struct scm_heap_seg_data): Doc fixes.
1205 * gc.c (scm_gc_sweep): Empty all segments' freelists before
1206 sweeping. Then, prepend each segment's free cells to its
1207 freelist, rather than wiping out the old value. (Thanks to Marius
1210 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
1211 scm_check_freelist, scm_debug_newcell): New functions and
1212 variables, for debugging freelist problems.
1213 * pairs.h (SCM_NEWCELL): New debugging version added.
1214 * gc.h (scm_debug_newcell): Added extern declaration, used by
1215 debugging version of SCM_NEWCELL.
1217 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1219 On some systems <libc.h> conflicts with <unistd.h>, and should not
1220 be #included at all.
1221 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
1222 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
1223 * configure.in: Call it.
1224 * posix.c, filesys.c: Use its results to decide whether or not to
1226 * configure, scmconfig.h.in: Rebuilt with autoconf and
1229 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1231 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
1232 pointer to the stdio stream before calling scm_setbuf0, so the
1233 latter will be able to retrieve it. I'm surprised this didn't
1234 segfault earlier. (Thanks to Christopher Lee.)
1236 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1238 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
1241 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1243 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
1244 number of stack narrowing specifier pairs. The first specifier in
1245 a pair controls inner border, the second the outer border. A
1246 number means cut that number of frames, a procedure object means
1247 cut until that object is found in operator position in a frame.
1249 * root.c (cwdr): Bugfix.
1251 * read.c: Recording of positions disabled by default.
1253 * procs.c (scm_closure_p): New function.
1255 * posix.c (scm_tmpnam): New function.
1257 * load.c: Added #include "throw.h".
1258 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
1261 * load.c, load.h (scm_read_and_eval_x): New function.
1263 * eval.c: Renamed debug option "deval" to "debug".
1265 (scm_eval_x): `eval!' is no longer accessible from the scheme
1266 level. Motivation: We can't allow operations which introduce
1267 glocs into the scheme level. Guile's type system can't handle
1268 these as data. Use `eval' or `read-and-eval!' as replacement.
1270 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
1271 SCM_CONSP since this is a macro!; Set vframe.prev to
1272 scm_last_debug_frame instead of 0. In this way we can look
1273 "above" the virtual start stack frame if we wish.
1274 (scm_debug_hang): New function: Useful for debugging Guile in
1275 certain tricky situations. Will probably be removed later...
1277 * debug.h: Changed semantics of debug option "backtrace". This
1278 option now only indicates whether we want automatic backtrace at
1281 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1283 * ports.c: #include "filesys.h"
1284 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
1286 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
1287 Motivation: This is system specific code which is related to file
1288 I/O. It also may use select. Added code by Gary Houston to
1289 detect presence of character in stdio buffers.
1291 * libguile.h: #include "libguile/libpath.h"
1293 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
1294 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
1295 SCM_SITE_DIR; Install libpath.h among the other include files.
1297 * load.c, load.h (scm_sys_package_data_dir): New function.
1299 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1301 * stacks.h: Bugfix: Don't use tail-array length field as stack
1302 length field! This screwed GC.
1304 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1306 * _scm.h: Added #ifndef around definition of macros min and max.
1308 * __scm.h: Added hooks for threads to plugin to in ints protection
1309 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
1310 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
1311 the main code in these macros duplicated and spread over multiple
1312 files. Renamed SCM_THREADS_SWITCHING_CODE ->
1313 SCM_THREAD_SWITCHING_CODE.
1315 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
1317 * snarf.h: New file.
1318 * guile-snarf.sh: New file.
1319 * Makefile.in (inner_h_files): Added snarf.h
1320 (ancillary, install, uninstall, distclean): Added actions for
1322 (.c.x): Use guile-snarf.
1323 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
1324 (gen_c_files): Note that these depend on guile-snarf.
1325 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
1326 now in "snarf.h". Added #include "snarf.h" to get them.
1327 * libguile.h: Added #include "snarf.h".
1328 (Patches applied and tweaked by Jim Blandy.)
1330 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1332 * socket.c: Use K&R style declaration for 'close'; the GNU coding
1333 standards suggest against providing prototypes for system
1334 functions. Thanks to Greg Troxel.
1336 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1338 * strports.c (scm_eval_0str): New function.
1339 #include "read.h", to get prototype for scm_read.
1340 * Makefile.in (strports.o): Update dependencies.
1341 * strports.h: New prototype.
1343 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
1344 scheme name from "int?" to "integer?". It seems to do the job.
1345 * numbers.h: Rename prototype too.
1346 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
1349 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
1350 scm_num_eq_p): Rename these according to R4RS conventions: call
1351 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
1352 to making libguile R4RS compliant without ice-9...
1354 * load.c (scm_sys_search_load_path): Search for files under all
1355 extensions listed in the %load-extensions variable. If FILENAME
1356 is absolute, return it unchanged, without searching the load path.
1357 (scm_loc_load_extensions): New variable, pointing to
1358 %load-extensions' value cell.
1359 (scm_init_load): Initialize it, and the value it points to.
1360 (scm_primitive_load_path): Improve error reporting.
1362 * load.c (scm_loc_load_hook): New variable, pointing to value cell
1363 of new Scheme variable %load-hook.
1364 (scm_primitive_load): Apply %load-hook to filename.
1366 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
1368 * configure.in: add tests for figuring out whether buffered data
1369 is available in a FILE structure, which is needed by char-ready.
1371 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
1374 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
1375 exceptions using misc_error instead of syserror. It seems a bit
1376 odd to throw an exception if a string can't be found in the
1377 environment, but it's consistent with open-file, stat etc.
1378 (simpos.h): remove sys_ from getenv.
1380 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
1381 occurs, throw an error instead of returning errno. Return value
1383 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1385 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1387 * filesys.c (scm_stat2scm): derive file type and permissions from
1388 the stat mode and append them to the returned vector.
1389 There isn't much overhead in doing this and it avoids the need to
1390 work with S_IRUSR et al. in Scheme.
1391 Define symbols scm_sym_regular etc.
1392 (scm_init_filesys): don't intern S_IRUSR etc.
1394 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1395 and s_primitive_load_path.
1397 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1399 * error.h: don't declare error symbols. prototype for scm_misc_error.
1401 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1404 * error.c: use SCM_SYMBOL to set up error keys.
1405 scm_misc_error: new procedure.
1407 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1409 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1410 between `#!' and `!#' is ignored.
1411 (skip_scsh_block_comment): New function.
1413 * feature.c (scm_set_program_arguments): New argument, FIRST.
1414 * feature.h: Update prototype.
1415 * init.c (scm_boot_guile_1): Pass new argument to
1416 scm_set_program_arguments.
1418 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1420 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1421 (scm_boot_guile): Call scm_set_program_arguments here, later than
1422 the old initialization.
1424 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1425 initialization procedure.
1426 - Delete in, out, err arguments; there are other perfectly good
1427 ways to override these when desired.
1428 - Delete result argument; this function shouldn't ever return.
1429 - Rename init_func argument to main_func, for less confusion.
1430 - Delete boot_cmd argument; main_func is more general.
1431 -Add 'closure' argument, to help people pass data to main_func
1432 without resorting to global variables.
1433 - Abort if reentered; don't bother returning an error code.
1434 - Call scm_init_standard_ports to set up the default/current
1435 standard ports; no need to pass them to scm_start_stack.
1436 - Remove code to evaluate the boot_cmd, and start the repl; let
1437 the user do something like that in main_func if they want.
1438 - Remove code to package up a return value; main_func can do any
1440 - Call exit (0), instead of returning.
1441 (scm_start_stack): Don't initialize the I/O ports here; that's
1442 weird. Delete in, out, err arguments. Move guts to
1443 scm_init_standard_ports, scm_stdio_to_port.
1444 (scm_init_standard_ports): New function, to set up current and
1445 default standard ports.
1446 (scm_start_stack, scm_restart_stack): Make these static.
1447 * init.h (scm_boot_guile): Adjust declaration.
1448 (scm_start_stack, scm_restart_stack): Remove externally
1449 visible declarations for these.
1450 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1452 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1453 written out several times in scm_start_stack.
1454 * fports.h: New declaration for the above.
1456 * feature.c (scm_set_program_arguments): New function.
1457 * feature.h: New declaration for the above.
1459 * ports.c: Formatting tweak.
1461 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1463 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1464 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1465 for obtaining the address of a car or cdr field. Motivation:
1466 &SCM_CXR make assumptions about the internal structure of the
1469 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1470 Motivation: see SCM_CXRLOC.
1472 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1473 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1474 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1475 Motivation: Safer use. Some other macros are defined in terms of
1476 these operations. If these are defined using the SCM_SETCXR
1477 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1478 to inefficiency and an <e1> with side-effects could potentially
1479 break. Also, these particular operations are heavily utilized in
1480 the garbage collector. In unoptimized code there will be a
1483 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1484 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
1485 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,

1488 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1489 vports.c: Cleaned up use of pairs: Don't make any special
1490 assumptions about the internal structure of selectors and
1491 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1492 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1493 (Among other things, this change makes it easier to build Guile
1494 with certain compilers which have problems with casted lvalues.)
1496 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1498 * stacks.c: Improve selection of relevant stack frames when making
1499 a stack object. Introduce one level of indirection in the stack
1500 object to make it possible to "narrow" to a certain region of the
1501 stack. This facilitates making use of more clever algorithms (not
1502 implemented) for selecting relevant frames and gives a cleaner
1503 design since selection of frames can be done independently of
1504 extraction of frames from the real stack.
1505 (scm_stack_id): Also take #t as argument which means look at
1508 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1509 Turn n_tail into an integer directly representing current number
1510 of frames in stack. Add field tail.
1512 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1514 * debug.c (scm_make_memoized): Made it available at scheme level.
1515 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1516 SCM_NIMP before applying heavier predicates in argument checking.
1517 (scm_local_eval): Also take memoized object as argument.
1519 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1520 aren't created with zero length, but should such a strange
1521 creature suddenly turn up...
1523 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1525 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1526 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1528 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1530 * variable.c (scm_make_variable): Make the name hint optional, as
1532 (anonymous_variable_sym): Renamed from variable_sym. All uses
1535 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1536 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1537 of scm_primitive_load_path was also changed to
1538 "primitive-load-path", from "%try-load-path". Callers changed.
1539 We'd like to respect the convention that a function named
1540 "try-mumble" should behave just like the function called "mumble",
1541 but return #f instead of signalling some error.
1542 * load.h: Rename prototypes.
1544 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1546 * print.c (make_print_state, grow_print_state), print.h: Modified
1547 the print state representation: Don't use a tail array for
1548 recording of circular references. Resizing of the print state
1549 structure invalidates the print state pointer. To avoid passing
1550 around an indirect print state reference to all printing
1551 functions, we instead let the print state reference a resizable
1554 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1556 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1557 Don't crash when passed an improper list terminated by a
1558 non-immediate value.
1560 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1562 Allocate data for structures on an eight-byte boundary, as
1563 required by the tagging system.
1564 * struct.c (alloc_struct): New function.
1565 (scm_make_struct, scm_make_vtable_vtable): Call it.
1566 * struct.h (scm_struct_n_extra_words): Bump to 3.
1567 (scm_struct_i_ptr): New "field".
1568 * gc.c (scm_gc_sweep): When we need to free the data, use the
1569 information stored by alloc_struct to find the beginning of the
1570 block allocated to the structure, so we can free it.
1572 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1574 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1577 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1578 (scm_debug_info): New member: id.
1580 * stacks.c: Stacks are now represented as structs; Stacks have an
1581 id given to them by `start-stack'.
1582 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1584 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1585 Changed stack representation.
1587 * debug.c (scm_procedure_name): Try procedure property `name' for
1588 compiled closures aswell.
1590 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
1592 * eval.c: scm_i_name moved to gsubr.c
1593 (scm_m_define): Record names of all kinds of procedure
1594 objects. (Earlier, only closures were recorded.)
1596 * procprop.h: Added declaration of scm_i_name.
1598 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1599 (scm_make_gsubr): Record names of compiled closures.
1601 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1603 * debug.c, debug.h: Removed obsolete code.
1605 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1606 stacks.c: Renamed regs --> scm_contregs.
1608 * print.c (scm_free_print_state): Cleanup print state before
1609 returning it to pool. It is better to do it here than in
1610 scm_prin1 since scm_prin1 is called often.
1612 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1613 s_set_source_property_x): Check that first argument is a pair or a
1616 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1617 scm_i_line, scm_i_column and scm_i_breakpoint global.
1619 * init.c: Added #include "backtrace.h" and #include "stacks.h".
1620 (scm_boot_guile_1): Added calls to scm_init_backtrace and
1623 * debug.h: Added debug object smob declaration and macro
1626 * configure.in: Build with backtrace.o and stacks.o if debug
1629 * Makefile.in: Added entries for new files: backtrace.c,
1630 backtrace.h, stacks.c and stacks.h.
1632 * symbols.c (scm_sym2ovcell): Fixed documentation.
1634 * _scm.h (min, max): Added.
1636 * async.c: Moved `min' macro to _scm.h.
1638 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1639 SCM_BACKTRACE_INDENT.
1641 * eval.c: Added new debug options `maxdepth' and `indent'.
1643 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
1645 * print.h: Added selector SCM_PRINT_STATE.
1647 * print.c: New functions: scm_make_print_state,
1648 scm_free_print_state.
1650 * print.h: Added declarations for scm_make_print_state,
1651 scm_free_print_state.
1653 * debug.c (scm_m_start_stack): New acro.
1655 * debug.h: Small cleanup.
1657 * init.c (scm_boot_guile_1): Moved scm_init_debug below

1680 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
1681 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
1682 declare functions with prototypes. (Patch thanks to Marius
1685 More prototype-related changes from Marius Vollmer:
1686 * gdb_interface.h: Wrapped header file in #ifdef/#endif
1687 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
1688 * ports.h (ptobfuns): Added prototypes. This means some casting in
1690 * fports.c: Added casts for initializations, since the functions
1691 are defined to take FILE * as their stream argument, not SCM.
1692 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
1693 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
1694 to `char *str_data' to conform to prototype.
1696 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1698 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
1700 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
1702 * stime.c, stime.h: use SCM_P method.
1704 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1706 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
1707 be given at least two arguments. Insist that lst's last element
1708 be a list, but don't make any requirements of its predecessors.
1710 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1712 * eval.c (scm_nconc2last): Revert last change; there seems to be
1713 other stuff going on here.
1715 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1717 * eval.c (scm_nconc2last): Make sure that each element of lst
1718 (which is a list of argument lists, except for the tail) is a
1719 proper list, i.e., finite and terminated by '().
1721 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1723 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
1726 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
1727 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
1730 * vectors.c (scm_make_vector): Fill vectors with the undefined
1731 value, to help make Guile Scheme code more portable to other
1734 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
1735 * symbols.h, tags.h: Doc fixes.
1737 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
1739 * async.c (scm_take_signal): Doc fixes.
1741 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
1743 * numbers.c (scm_divbigint): When the remainder is zero, we don't
1744 want to subtract it from the modulus; we just want to leave it
1747 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
1749 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
1752 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
1754 * throw.c (scm_catch_apply): Finished implementation of
1757 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
1759 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
1761 (scm_init_filesys): set "i/o-extensions" feature.
1764 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
1766 * Makefile.in (root.o): Correct dependencies.
1768 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
1770 * Makefile.in: Added dependency entry for root.o.
1772 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
1773 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
1775 * init.c (scm_start_stack): Set initial root continuation number
1778 * procs.c: New function: scm_thunk_p.
1780 * procs.h: Added declarations of scm_thunk_p.
1782 * root.c: Renamed `call-with-new-root' -->
1783 `call-with-dynamic-root'.
1784 (cwdr): Removed allocation of new root state. This should be done
1785 separately by use of scm_make_root.
1786 (scm_apply_with_dynamic_root): New function: Does what it
1787 sounds like. Needed when spawning threads.
1789 * root.h: Added member last_debug_frame to root state.
1790 Added #include "libguile/debug.h"
1792 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
1793 arguments. The motivation is that code in root.c needs catch
1794 functionality, and we want to avoid code duplication.
1795 New functions: scm_catch, scm_lazy_catch. These are wrappers for
1796 scm_catch_apply. scm_lazy_catch is intended to introduce catch
1797 handlers that run without popping the stack into the dynwind
1800 * throw.h: Added prototypes for scm_catch_apply and
1803 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1805 * root.h (scm_root, scm_set_root): Decouple thread support details
1806 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
1807 SCM_SET_THREAD_LOCAL_DATA.
1809 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
1810 and tortoise scanning loop.
1812 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
1814 * Makefile.in: Rebuild dependencies.
1816 * libguile.h: #include "libguile/print.h" before "smob.h", since
1817 the latter uses the print_state structure.
1819 * throw.c (scm_ithrow): Use the correct variable when checking to
1820 see if a given element of scm_dynwinds is a valid catch.
1822 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
1823 structure, abort; don't just silently ignore the garbage.
1825 * _scm.h: #include "print.h" here, since it seems to be used just
1827 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
1828 strports.c, unif.h: Don't #include "print.h".
1830 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1832 * feature.h (scm_loc_features): Removed external declaration.
1833 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
1835 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1837 * feature.c (scm_init_feature): Added threads feature (needs to be
1838 initialized here, since features doesn't exist when
1839 scm_init_threads is called).
1841 * libguile.h: Added #include "libguile/../threads/threads.h".
1842 (This is a kludge to get thread support working. This should be
1845 * configure.in, acconfig.h: Added flags for thread support.
1847 * scmsigs.c: Define `signal' to be `pthread_signal' if using
1850 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
1851 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
1854 * _scm.h: Added conditional #include "threads.h"
1856 * __scm.h (SCM_ASYNC_TICK): Added call to macro
1857 SCM_THREADS_SWITCHING_CODE.
1859 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
1860 allocate the basic dynamic root object.
1861 (scm_boot_guile): Added call to scm_init_root.
1863 * root.c, root.h: Added root smob.
1864 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
1865 functions: Implements dynamic roots mostly according to spec in
1866 SCM manual. Main difference is that the second argument is a
1867 throw handler rather than an error "thunk".
1869 * root.h: Added declaration of scm_init_root.
1871 * root.c: Added #include "genio.h", #include "smob.h", #include
1872 "pairs.h", #include "throw.h", #include "dynwind.h", #include
1874 (scm_init_root): Added #include "root.x".
1876 * throw.c: Added #include "stackchk.h"
1877 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
1878 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
1879 can be used in scm_call_with_new_root; Added reenabling of stack
1880 checking when catching a throw.
1882 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
1884 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
1886 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
1887 element is not found, as per R4RS.
1889 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1891 * list.c: Doc fixes throughout.
1893 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1895 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
1896 declare the char * to be const. Avoids a warning in rgx.c.
1898 * ports.h: spelling fix.
1900 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
1903 * load.c (scm_sys_try_load_path): throw an error if file not found
1904 (like it says it in NEWS).
1906 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1908 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
1909 PROPS slot to '(), not #f; it's an empty alist.
1911 * throw.h, throw.c: Use SCM_P instead of #if hair.
1913 Remove special support for uncaught throws; see throw.c for
1915 * throw.c (uncaught_throw): New function.
1916 (scm_ithrow): Call uncaught_throw if we don't find a throw
1917 target; don't mess with scm_bad_throw_vcell.
1918 (scm_bad_throw_vcell): Variable deleted.
1919 (scm_init_throw): Don't initialize it.
1921 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
1924 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1926 * numbers.c (scm_istr2int): If the number is short (as most
1927 numbers are), just call scm_small_istr2int to deal with it.
1928 (scm_small_istr2int): New function, created by un-#ifdefing the
1929 non-bignum version of scm_istr2int and renaming it.
1931 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
1933 * load.c (scm_sys_try_load): don't check whether value returned
1934 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
1935 Change the Scheme name from %try-load to primitive-load.
1937 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
1938 Can avoid passing a message, allowing it to be derived in the
1939 error handler (e.g., if we want to throw to the key both from
1942 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
1944 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
1945 references now have a new appearance which is more compact and
1946 also gives a clue about what the target of the reference is.
1947 By setting parameters in the print state, more fancy printing can
1948 be achieved. This is used by the (not yet commited) backtrace
1951 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
1953 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
1956 * print.c: Added #include "struct.h". Removed function
1959 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
1960 scm_iprin1. Removed prototype for scm_prlist.
1962 * arbiters.c (prinarb),
1963 async.c (print_async),
1964 debug.c (prindebugobj, prinmemoized),
1965 eval.c (prinprom, prinmacro),
1966 filesys.c (scm_fd_print, scm_dir_print),
1968 mallocs.c (prinmalloc),
1969 numbers.c, numbers.h (scm_floprint, scm_bigprint),
1970 smob.h (scm_smobfuns),
1971 srcprop.c (prinsrcprops),
1973 unif.c, unif.h (scm_raprin1, rapr1),
1974 variable.c (prin_var): Changed argument `int writing' to
1975 `scm_print_state *pstate'.
1977 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
1978 that it will be called before scm_init_print.
1980 * print.c (scm_prin1): Print states are now allocated when calling
1981 scm_prin1 and then passed around to all printing functions as an
1982 argument. A cache `print_state_pool' enables reuse of print
1984 (scm_make_print_state): New function.
1985 (scm_iprin1): Adaption to print states.
1986 (scm_iprlist): An initial "hare and tortoise" scan brings down
1987 time complexity to O (depth * N). (Better time complexity will be
1988 achieved when the printing code is completely rewritten.)
1990 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1992 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
1993 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
1994 it gets done whether or not the cache variable has a value.
1996 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
1998 Distinguish #f and ().
1999 * __scm.h: #undef SICP.
2000 * pairs.h (SCM_EOL): Delete this definition, equating it with
2002 * tags.h (SCM_EOL): Give it a new definition here; I think I found
2003 the value it used to have. Doc fixes, too.
2005 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
2007 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
2008 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
2009 Lord's implementation of structs, allowing for tail arrays as
2010 described in the manual. Also fixed some bugs. (Both the interface
2011 and the implementation should be improved.)
2013 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
2015 * print.c, print.h: Closures now print like #<procedure foo (x)>.
2016 People who whish to see the source can do `(print-enable 'source)'.
2017 Removed #ifdef DEBUG_EXTENSIONS.
2019 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2021 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
2022 integer (assuming for now accepting an integer is a good thing).
2024 * error.c, fports.c: replace use of %S in lgh_error args with %s.
2025 %S will be used instead for write'ing arguments.
2027 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
2028 asserts. fix a few other asserts.
2029 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
2030 scm_uniform_vector_ref, scm_array_set_x,
2031 scm_dimensions_to_unform_array): change args in
2032 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
2033 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
2034 scm_substring_fill_x): likewise.
2035 gsubr.c (scm_gsubr_apply): likewise.
2036 eval.c (SCM_APPLY): likewise.
2038 * eval.c (4 places): replace scm_everr with lgh_error or
2041 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
2042 scm_memory_error): new procedures.
2043 scm_everr: deleted. can use scm_wta, dropping first two args.
2044 scm_error: convert NULL subr to SCM_BOOL_F.
2046 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
2049 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
2052 * error.c, error.h: new error keys: scm_arg_type_key,
2053 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
2055 scm_wta: reimplement using lgh_error instead of scm_everr.
2057 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
2059 * gdbint.c: scm_lread now has one more argument.
2061 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
2062 scm_port_\1; Added mutator scm_set_port_filename_x (used when
2063 loading source from non-file ports, which, e. g., happens when
2064 using the Emacs interface).
2066 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
2069 * read.c: Added code for recording of positions of source code
2070 expressions; New functions: recsexpr, scm_lreadrecparen;
2071 _scm_make_srcprops --> scm_make_srcprops
2072 (scm_flush_ws): Removed updating of positions counters. This work
2073 is already done by scm_gen_getc
2075 * read.h: Added prototype for scm_lreadrecparen
2077 * print.c: Added #include "alist.h"
2079 * eval.c: Added #include "hash.h"
2081 * eq.c: Added #include "ramap.h"
2083 * options.c: Documentation fixes.
2085 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
2086 (scm_init_srcprop): Adjusted size of initial source-whash. Name
2087 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
2088 --> scm_make_srcprops
2090 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
2091 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
2092 function calls in the definition of the whash access macros.
2094 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
2096 * init.c (scm_boot_guile): Add level of indirection to
2097 scm_boot_guile_1() to ensure that stack base pointer is properly
2098 initialized. There was no guarantee that variable i was the
2099 highest/lowest variable on stack (i.e. the call frame of
2100 scm_boot_guile was not completely protected from gc).
2102 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
2104 * ports.h (scm_port_table): put back file_name, it will be used to
2105 support debugging. Undo related changes in fports.c, ioext.c,
2108 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2110 * ports.h (scm_port_table): remove file_name member for now, it seems
2112 * fports.c (scm_open_file): don't set file_name in PTAB.
2113 (prinfport): don't use file_name in PTAB.
2114 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
2115 * ports.c (scm_add_to_port_table): don't intialize file_name.
2116 (scm_port_file_name): remove for now.
2117 * gc.c (scm_gc_mark): don't mark PTAB file_name.
2119 * fports.h (scm_mkfile): prototype deleted.
2120 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
2122 * debug.c, unif.c: use scm_out_of_range instead of
2123 wta for range errors (ASSERT still needs work).
2125 * error.c, error.h (scm_out_of_range): new procedure.
2127 * error.c, error.h (scm_out_of_range_key): new key.
2129 * posix.c (scm_sync): #else was missing.
2131 * error.c, error.h: append _key to names scm_num_overflow and
2134 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
2135 of consing an empty list.
2136 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
2137 of macros, saves code and string space.
2138 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
2139 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
2140 lower case. Rename scm_syserror_m to scm_syserror_msg.
2141 error.h: prototypes for new procedures.
2143 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
2145 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
2147 * error.c, error.h: setup scm_num_overflow key.
2149 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
2150 Remove definition of SCM_OVSCM_FLOW.
2152 * fports.c (scm_open_file): use SCM_SYSERROR_M.
2154 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
2155 explicit message and args.
2157 * error.c, error.h, __scm.h: change system_error_sym to
2160 * error.c (system_error_sym): remove leading %% from the Scheme name
2163 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
2165 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2167 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
2168 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
2169 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
2170 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
2171 renamed. (These were introduced by unsupervised name
2174 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2176 * print.c: Added code for detection of circular references during
2177 printing. (init_ref_stack, grow_ref_stack): New functions. Added
2178 a hook for printing of closures (accessible via print options).
2179 This leads to a split of calls to scm_iprin1 into two classes:
2180 elementary print operations (e. g. the code which prints a smob)
2181 still use scm_iprin1 while top level calls (like scm_display) use
2182 scm_prin1. scm_prin1 begins by clearing the data structure used
2183 to record reference information.
2185 * print.h: Added declarations of scm_prin1 and scm_prlist.
2187 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
2189 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
2191 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
2193 * error.c (err_head): scm_iprin1 --> scm_prin1
2195 * debug.c: Adjusted header comment.
2199 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2201 * strerror.c: Doc fix.
2203 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2205 * gdbint.c (gdb_read): Now possible to run during GC.
2206 (unmark_port, remark_port): New functions.
2208 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
2210 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
2211 of allocating a new string object. Also, increase size by
2212 the factor 2 instead of 1.5.
2214 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
2216 * __scm.h (SCM_P): Corrected to run under traditional C.
2218 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
2221 * async.c: Calls to scm_sysintern corrected.
2223 * async.h (scm_async_clock): Redundant declaration removed.
2225 * continuations.c (scm_dynthrow): Redundant declaration removed.
2227 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
2228 Definition typos corrected.
2230 * debug.h: Missing declarations of functions in debug.c added
2233 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2234 Missing declarations to functions in eval.c added.
2236 * filesys.c: Possibly uninitialized variable rv.
2238 * gc.h (scm_object_addr, scm_unhash_name): Missing
2239 declarations of functions defined in gc.c added.
2241 * genio.c: Possible typos str_data -> wstr_data. ???
2243 * genio.c: Possibly unintended shadowing of local variable
2244 `int c' (gotos out of scope of inner `c'). ???
2246 * init.c: Uninitialized `SCM last' may be used.
2248 * ioext.h: (scm_sys_isatty_p): Typo.
2250 * list.h (scm_list_head): Missing prototype for function in
2253 * numbers.c (scm_two_doubles): Changed from extern to static
2254 (is used only within numbers.c).
2256 * numbers.h: Repeated declarations removed.
2258 * ports.h (scm_close_all_ports_except): Declaration for the
2259 function defined in ports.c added.
2261 * posix.h: Missing declarations added.
2263 * procs.h (scm_make_subr_opt): Missing declaration added.
2265 * socket.h (scm_sys_gethost): Missing declaration added.
2267 * socket.h: Redundant declarations removed (they are in fdsocket.h).
2269 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
2270 Missing declarations added.
2272 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
2274 * struct.c: Uninitialized variable `SCM answer' may be used.
2276 * unif.c (l2ra): Declaration prototype.
2278 * unif.c (scm_array_equal_p): Dummy definition removed (it is
2279 defined in ramap.c).
2281 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
2282 Redundant declarations removed (they are in ramap.h).
2284 * variable.h (scm_make_udvariable,
2285 scm_make_undefined_variable): Declaration corrected to
2286 correspond variable.c.
2288 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
2289 Missing declarations added.
2291 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
2293 * Makefile.in (distclean): Don't forget to delete fd.h.
2295 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2297 * fd.h.in, tags.h: Trivial cleanups.
2299 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
2300 marksweep.h just declared functions from gc.c.
2301 * gc.h, libguile.h: Don't #include "marksweep.h".
2302 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2303 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
2304 dependencies updated.
2306 * libguile.h: Don't #include "files.h"; it's been deleted.
2308 * files.c (scm_sys_delete_file): Moved to filesys.c.
2309 File is now empty; deleted.
2311 * filesys.c: scm_sys_delete_file is now here. Remove
2312 #if's; they seem to rely on remnants of an old portability
2313 regimen. If the problems come up again, solve them properly,
2314 using autoconf. Specifically: Don't test M_SYSV, and #define
2315 remove to be unlink if it's #defined; don't use remove just
2316 because HAVE_STDC_HEADERS is #defined.
2317 * filesys.h: Add declarations for scm_sys_delete_file.
2318 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2319 files.o, files.h, files.c, and files.x.
2320 * init.c: Don't #include "files.h", and don't call scm_init_files.
2322 Use SCM_P instead of PROTO; the latter intrudes on the user's
2324 * params.h: Deleted; definition of SCM_P moved to...
2325 * __scm.h: ... here, where it replaces PROTO macro.
2326 * libguile.h, smob.h: Don't #include "params.h".
2327 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
2328 smob.h: Fix prototypes accordingly.
2329 * Makefile.in: Update dependencies.
2330 (inner_h_files): Remove params.h.
2332 * gc.c: #include "gc.h"; every module should include its header,
2333 to let the compiler cross-check the declarations against the
2336 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2337 simpos.h: #include "libguile/__scm.h".
2339 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2341 * init.c: Don't forget to #include smob.h and init.h.
2342 * Makefile.in: Dependencies updated.
2344 * smob.h: Use PROTO instead of #if __STDC__.
2346 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2348 * __scm.h: Doc fixes.
2350 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2351 <angles>; this allows `make depends' to work properly.
2353 * libguile.h: #include smob.h and pairs.h before the others; they
2354 define typedefs used by other headers.
2356 C files should #include only the header files they need, not
2357 libguile.h (which #includes all the header files); the pointless
2358 recompilation was wasting my time.
2359 * Makefile.in (all .o dependency lists): Regenerated.
2360 * libguile.h: Don't try to get a definition for size_t here...
2361 * __scm.h: Do it here.
2362 * _scm.h: Since this is the internal libguile header, put things
2363 here that all (or a majority) of the libguile files will want.
2364 Don't #include <libguile.h> here; that generates dependencies on
2365 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2366 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2367 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

2464 * weaks.c: Get "weaks.h".
2466 * stackchk.h: #include "libguile/debug.h",
2468 * print.h, read.h: #include "options.h", since everyone who uses
2469 either of these files will need that.
2471 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2472 anyone who uses this file will need them to define the smob
2473 printing functions. Also, get markers.h, since people will need
2474 to #define the mark functions.
2476 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2477 * ports.h: ... to here.
2479 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2480 don't rely on archaic C default type rules.
2482 * fports.h: #include "libguile/ports.h", since you need that in
2483 order to parse this.
2485 * genio.h: #include "libguile/print.h", because you need that to
2486 parse this; don't bother #including "ports.h", since print.h gets
2489 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2491 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2492 this; it's now a reference to an element of *scm_root.
2494 * debug.h: Don't #include "options.h"; the compiler won't be able
2495 to find that once the headers are installed; instead, #include
2496 "libguile/options.h".
2497 * gc.h: Same, with marksweep.h.
2498 * mbstrings.h: Same, with symbols.h.
2499 * scmhob.h: Same, with _scm.h.
2500 * smob.h: Same, with params.h.
2502 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2503 C files; there's no need for this, and it forces recompilations
2506 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2508 * error.c (scm_error): declare scm_error_callback.
2510 * error.h: prototype for scm_error_callback.
2512 * __scm.h: define lgh_error.
2513 (SCM_SYSERROR): redefine using lgh_error.
2515 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2517 * error.c (scm_error): new procedure.
2519 * error.h: prototype for scm_error.
2521 * Makefile.in (install): install scmconfig.h from the current
2522 directory, not $(srcdir).
2524 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2526 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2527 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2528 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
2529 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
2530 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
2531 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,

2534 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2535 vports.h, weaks.h: #include "libguile/__scm.h", not
2536 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2537 dependencies are within libguile properly.
2539 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2541 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2542 when scmconfig.h doesn't exist.
2544 * load.c (scm_sys_try_load): Correct spelling.
2546 * feature.c (scm_loc_features): Make this static.
2548 * Makefile.in (libpath.h): Omit trailing slash from path. We
2549 shouldn't require it of users, so why put it here?
2551 Move code to initialize and search %load-path from ice-9 to C
2552 code, so we can use the load-path to find the ice-9 boot code;
2553 this makes it easier to run Guile without installing it. See
2554 corresponding changes in guile/Makefile.in.
2555 * feature.c: Move stuff concerned with the load path to load.c.
2556 (scm_compiled_library_path): Deleted.
2557 Don't #include libpath.h here.
2558 * feature.h: Don't mention scm_compiled_library_path.
2559 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2560 <sys/stat.h>, and <unistd.h> (if present).
2561 (R_OK): #define if the system hasn't deigned to.
2562 (scm_loc_load_path): New variable.
2563 (scm_init_load_path, scm_sys_search_load_path,
2564 scm_sys_try_load_path): New functions.
2565 (scm_init_load): Initialize scm_loc_load_path to point to the
2566 value cell of the Scheme %load-path variable.
2567 * load.h: Add declarations for scm_sys_search_load_path,
2568 scm_sys_try_load_path.
2569 * init.c: Call scm_init_load_path.
2570 * Makefile.in (feature.o, load.o): Dependencies updated.
2572 * load.c, load.h: Rewrite using PROTO macro.
2574 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2576 * gc.c (scm_cellp): New function: C predicate to determine if an
2577 SCM value can be regarded as a pointer to a cell on the heap.
2579 * gc.h: Added declaration of scm_cellp.
2581 * gdb_interface.h: New file: The GDB interface header from the GDB
2584 * gdbint.c: New file: GDB interface.
2586 * gdbint.h: New file: GDB interface.
2588 * libguile.h: Added #include <libguile/gdbint.h>.
2590 * init.c (scm_boot_guile): Added scm_init_gdbint.
2592 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2593 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2594 found if object files and source are kept separate).
2596 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2598 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2600 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2602 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2603 TK_SRC_DIR; they're not relevant any more.
2605 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2606 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2608 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2610 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2611 search path, so we can find the <libguile/MUMBLE.h> headers.
2613 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2615 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2616 implicit in the .c.o rule.
2617 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2620 Put the library path in a header file, instead of passing it on
2621 the command line in every compilation.
2622 * Makefile.in (libpath.h): New target.
2623 (feature.o): Depend on libpath.h.
2624 (clean): Delete libpath.h.
2625 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2626 * feature.c: ... #include "libpath.h" here.
2627 * .cvsignore: Ignore libpath.h.
2629 Don't install the unwashed masses of Guile header files in the
2630 main #include path; put most of them in a subdirectory called
2631 'libguile'. This avoids naming conflicts between Guile header
2632 files and system header files (of which there were a few).
2633 * Makefile.in (pkgincludedir): Deleted.
2634 (innerincludedir): New variable; this and $(includedir) are enough.
2635 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
2636 (installed_h_files): Divide this up. Now this variable lists
2637 those header files which should go into $(includedir) (i.e. appear
2638 directly in the #include path), and ...
2639 (inner_h_files): ... this new variable says which files appear in
2640 a subdirectory, and are referred to as <libguile/mumble.h>.
2641 (h_files): List them both.
2642 (install): Create innerincludedir, not pkgincludedir. Put
2643 the installed_h_files and inner_h_files in their proper places.
2644 (uninstall): Corresponding changes.
2645 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2646 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2647 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
2648 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
2649 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
2650 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2651 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2652 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2653 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2654 vports.h, weaks.h: Find __scm.h in its new location.
2655 * __scm.h: Find scmconfig.h and tags.h in their new locations
2656 (they're both "inner" files).
2658 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
2660 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
2662 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2664 * posix.c: Doc fixes.
2666 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
2668 * socket.c: Don't include a prototype for inet_aton; just use a
2669 K&R style declaration, to avoid warnings but minimize the chance
2670 of conflicts with the system.
2672 On NextStep, <utime.h> doesn't define struct utime, unless we
2673 #define _POSIX_SOURCE before #including it.
2674 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
2675 * acconfig.h: New comment text for above CPP symbol.
2676 * configure.in: Call it.
2677 * posix.c: #define _POSIX_SOURCE if it seems necessary.
2679 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
2681 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
2682 testing for __EMX__.
2684 * posix.c: #include <libc.h>, if it exists.
2686 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
2687 don't even know if the latter exists.
2689 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
2690 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
2691 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
2693 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
2695 (scm_init_posix): Use them when initializing the Scheme constants
2698 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2700 * Makefile.in (libdir, includedir, bindir): Use the
2701 autoconf-supplied values, instead of deriving them ourselves.
2702 (pkgincludedir, datadir, pkgdatadir): New variables.
2703 (install, uninstall): Put the header files in a special
2704 subdirectory, not in the main search path.
2706 * Makefile.in (ALL_CFLAGS): Provide the proper value for
2707 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
2709 * Makefile.in (IMPLPATH): Deleted; never used.
2711 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
2712 on the Tcl/Tk source any more.
2713 (INCLUDE_CFLAGS): Remove references to the above.
2715 * Makefile.in (version.o): Corrected dependencies.
2717 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
2719 * libguile.h: #include "version.h"
2721 * init.c (scm_boot_guile): Call scm_init_version.
2722 * gscm.c (gscm_run_scm): Call scm_init_version.
2724 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
2725 GUILE_VERSION): AC_DEFINE these.
2726 (acconfig.h): #undef the above symbols.
2728 * Makefile.in (libobjs): Add version.o.
2729 (installed_h_files): Add version.h.
2730 (c_files): Add version.c.
2731 (gen_c_files): Add version.x.
2732 (version.o): New rule.
2733 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
2734 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

2743 weaks.o): Add version.h to dependency lists.
2744 (markers.o): Remove duplicate rule.
2746 * version.h: New file.
2748 * version.c: New file.
2750 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2752 * symbols.c (scm_strhash): scm_downcase is now a function, not an
2753 array; use it appropriately. Since GCC is quite happy to
2754 subscript functions, it never warned us about this; we should use
2755 -Wpointer-arith in the future. I guess we never tested
2758 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2760 * socket.c: Doc and copyright fixes.
2762 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2764 * debug.c: Fixed and improved gdb support.
2766 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2768 * socket.c: Added declaration of inet_aton to avoid compiler
2769 warning. (Hope this solution is correct.)
2771 * stime.c: Added declaration of ftime. (This is missing in
2774 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
2776 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2778 * Makefile.in (c_files): add strerror.c.
2780 * strerror.c: new file from Emacs' sysdep.c.
2781 maybe configure should also check for sys_errlist.
2783 * configure.in (AC_REPLACE_FUNCS): add strerror.
2785 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2787 * debug.c (scm_init_debug): Added initialization for
2788 scm_evaluator_traps.
2790 * debug.h, debug.c: Various name changes.
2791 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
2792 "debug-options-interface". See commentary in options.c.
2794 * options.h, options.c: Options now have documentation strings.
2795 Also added a long explanatory commentary.
2797 * eval.c, print.h, print.c, read.h, read.c: Modifications to
2800 * gscm.c, init.c, root.c, throw.c: Bug fixes:
2801 last_debug_info_frame is now updated in all cases.
2803 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
2806 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2808 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
2809 Added option STACK_CHECKING.
2811 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
2813 * Makefile.in: Added {debug,options,srcprop}.{h,c}
2815 * __scm.h: Removed symbols for debugging support.
2817 * acconfig.h: Added symbols for debugging support.
2819 * configure.in: Added user option for debugging support.
2820 --enable-debug will include the debugging code into libguile.a.
2822 * continuations.c (scm_make_cont): Enlarged the #if 0 around
2823 scm_relocate_chunk_to_heap.
2825 * debug.c: New file: low-level debugging support. It also
2826 includes support for debugging with gdb. (The extensions to gdb
2827 are written by Per Bothner at Cygnus.)
2829 * debug.h: New file: low-level debugging support.
2831 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
2832 argument pairs. Extensive modifications to the debugging
2833 evaluator. Added "SECTION:" commentaries to clarify what happens
2834 when, during double compilation. Renamed EVALIMP --> EVALIM.
2835 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
2836 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
2837 the beginning of the file. New procedure: scm_unmemocopy.
2838 Added some global state variables needed by the debugging
2839 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
2840 check_entry, check_apply, check_exit, debug_options and
2841 evaluator_traps. New acro: undefine.
2843 * eval.h: Renamed EVAL --> XEVAL.
2845 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
2846 --> scm_make_weak_key_hash_table.
2848 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
2849 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
2851 * libguile.h: Conditionally include debug.h
2853 * objprop.c (scm_object_properties, scm_set_object_properties_x):
2854 scm_object_properties shouldn't return handle. `handle' now gets
2855 initialized in scm_set_object_properties_x. scm_object_properties
2856 doesn't any longer create an entry in scm_object_whash.
2858 * options.c: New file: handling of run time options.
2860 * options.h: New file: handling of run time options.
2862 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
2864 * print.c: New procedure: scm_print_options
2866 * print.h: Defines for print options.
2868 * read.c: New procedure: scm_read_options
2870 * read.h: Defines for reader options.
2872 * root.h: Added scm_source_whash among scm_sys_protects.
2874 * srcprop.c: New file: source properties.
2876 * srcprop.h: New file: source properties.
2878 * throw.c (jbsmob): Jump buffers are now correctly allocated.
2879 (Bug found by A. Green.)
2881 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2883 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2885 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
2887 * libguile.h: #include "objprop.h"; I guess this was forgotten.
2889 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
2890 and should be called by the final client.
2892 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
2894 * gc.h: Use the PROTO macro when declaring functions.
2895 * gc.c: Use the PROTO macro when declaring static functions.
2896 Remove the CPP hair around function definitions.
2898 * gc.c (scm_init_storage): Initialize scm_asyncs.
2900 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
2901 preprocessor symbol; "__scm.h" is where it might get #defined.
2902 * __scm.h: Similar: #include <scmconfig.h> before testing
2905 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
2907 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
2909 * init.c (scm_boot_guile): Add init_func argument; call
2910 (*init_func) instead of calling scm_appinit; it's ucky to
2911 hard-code names for the user's procedures.
2912 * init.h (scm_boot_guile): Adjust declaration.
2914 * __scm.h (PROTO): New macro, for declaring functions with
2917 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
2918 eliminate all the __STDC__ conditionals.
2919 (scm_boot_guile): Add declaration.
2920 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
2921 Remove __STDC__ conditionals around function definitions; the
2922 declarations in init.h will provide the same information, more
2925 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
2926 complain about it in the error message; the error message is
2927 adequate without that note, and there's nothing the user can do
2930 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
2932 * Makefile.in (ancillary): Drop def.sed.
2934 * posix.c (scm_init_posix): Use numeric values, rather than
2935 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
2936 F_OK. The symbols aren't available on some systems, and I'm
2937 pretty sure their values are fixed by common widespread practice.
2938 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
2940 More functions unavailable on some systems.
2941 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
2942 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
2944 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2945 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
2946 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
2947 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
2948 stub that signals an error as the #else.
2950 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
2952 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
2954 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
2956 * unif.c: include ramap.h.
2958 * read.c (endif): case_insensative_p renamed case_insensitive_p.
2960 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
2962 * ports.c: include sys/ioctl.h.
2964 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
2966 * configure.in: check for sys/ioctl.h.
2968 * ports.c: include <malloc.h> not "malloc.h".
2970 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2972 * fports.c: remove ttyname and tmpnam declarations.
2974 * posix.c: fewer ttyname declarations.
2976 * fports.c: include <string.h> not "string.h".
2978 * init.c, ioext.c: include string.h and unistd.h.
2980 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2982 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
2983 genio.c, simpos.c, vports.c: include string.h.
2985 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
2987 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
2989 (scm_addr_buffer_size): change type from scm_sizet to int.
2990 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
2991 from scm_sizet to int.
2993 * error.c: include unistd.h.
2995 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
2998 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
3000 * __scm.hd, def.sed: deleted.
3002 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
3004 Changes for NeXT, suggested by Robert Brown.
3005 * configure.in: Call AC_TYPE_MODE_T.
3006 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
3007 NeXT. Put header file list in alphabetical order.
3008 * configure, scmconfig.h.in: Regenerated.
3009 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
3011 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
3014 * acconfig.h: New file, providing documentation for the CPP
3015 symbols defined in configure.in
3016 * acconfig-1.5.h: Removed; superceded by the above.
3018 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
3020 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
3022 * fports.c (scm_open_file): don't return #f, throw error.
3024 * ioext.c (fileno): renamed from %fileno.
3025 (soft-fileno): deleted.
3027 * ports.c (scm_port_revealed): don't need to check for -1 from
3029 (scm_set_port_revealed_x): return unspecified, not #f.
3031 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
3033 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
3035 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
3037 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
3039 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3041 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
3042 This is necessary on Ultrix, and doesn't hurt portability.
3044 * Makefile.in (dist-dir): New target, implementing a new dist system.
3045 (installed_h_files): Put in alphabetical order.
3046 Remove duplicate entries for markers.h and unif.h.
3047 (c_files): Remove duplicate entries for markers.c.
3048 (ancillary): Renamed from anillery; all uses changed. Remove
3049 PLUGIN; it's a directory, and needs special treatment in dist-dir.
3050 Remove all the ../doc/* files; doc/Makefile.in handles that.
3052 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
3054 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
3055 every if must have an else, or else the whole command has a
3056 non-zero exit code whenever the if's condition is false.
3058 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
3060 * posix.c: include string.h.
3062 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
3064 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
3067 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
3068 Remove leading % from scheme names.
3069 Do not return error values, call SCM_SYSERROR or similar.
3071 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
3073 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
3075 * struct.c (scm_init_struct): new file.
3077 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
3079 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
3080 (scm_list_head): added list-head for rapidly chopping argument
3081 lists off of longer lists (and similar).

3085 * objprop.c (scm_object_property): assq the cdr of the whash
3086 handle for obj, not the handle itself.
3088 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
3090 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
3091 weak hash tables last of all marking to avoid an obscure gc bug.
3092 WARNING: circular lists stored in a weak hash table will hose us.
3094 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
3096 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
3097 new functions similar to scm_substring_move_left_x and
3098 scm_substring_move_right_x.
3100 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
3102 * init.c (scm_boot_guile): prevent gc with scm_block_gc not

3107 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
3109 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
3111 * strports.c (scm_strprint_obj): convenience function. C for
3112 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
3114 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
3115 removed to a separate library
3117 * init.c (scm_boot_guile): copied from guile-tcl.c.
3118 Initialization specific to tcl interpreters removed.
3120 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
3122 * ports.c (scm_ports_prehistory): size malloced here doesn't
3123 matter so long as it is non-0 (got rid of "* 4").
3125 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
3127 * gscm.h: gscm_mkarray eliminated (presumably was not being used
3128 since its definition was bogus).
3130 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
3132 * mallocs.[ch]: back again (for rx at least).
3134 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
3136 * ports.c: removed functions relating to the mapping between ports
3137 and descriptors. (That stuff is unix-specific and should be collected
3138 in a separate library).
3140 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
3141 (Tom Mckay@avanticorp.com)
3143 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
3145 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
3146 handled correctly (SCM_FREEP was applied to them) -- test for
3147 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
3148 being overwritten with #f. (brown@grettir.bibliotech.com)
3150 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
3152 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs

3155 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
3157 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak

3167 Generalized assoc and hash-table functions.
3168 Factored pairs.c into multiple files.
3170 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
3172 * gscm.c (gscm_run_scm): got rid of objprop.

3180 NOTE: don't use a alist here.
3181 (scm_set_procedure_properties_x): fix type checking throughout this file.

3191 * vports.c (scm_make_soft_port): allocate a port table entry
3192 (possibly triggering gc) before setting the tag of the corresponding
3195 * pairs.c (scm_delq_x): never throw an error.
3197 * vectors.c (scm_make_vector): made the default vector fill argument
3198 into '() (much more useful than the previous value, "#unspecified")
3200 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
3202 * ports.c (scm_add_to_port_table): Added fields
3203 to port table entries: file_name, line_num, col.
3204 Update these in open_file, gen_getc and gen_ungetc.
3205 Added procedures to access those fields.
3207 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
3209 * procs.c (scm_make_subr_opt): new entry point for making

3223 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
3224 (scm_gc_stats): return an assoc of useful data. Replaces "room"
3225 and the stats reporting formerlly built into repl.

3228 GC statistics keeping moved to gc.c.
3229 Other statistics keeping can be done from Scheme.
3230 REPLS are now written in Scheme.

3239 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
3241 * feature.c (scm_compiled_library_path): moved here from repl.c.
3242 This file is for stuff relating specifically to Scheme libraries
3245 * eval.c (scm_m_define): don't give warning about redefinition, don't
3248 NOTE: this should throw a resumable exception with parameters --
3249 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
3251 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
3253 * error.c: scm_warn eliminated.

3265 between the call to procedurep and use.
3267 * error.c (scm_everr):
3269 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
3272 * strports.c: don't reveal the port's string to the caller
3273 because it changes size.
3275 (stputc stwrite): check/change the strings length with interrupts
3278 * objprop.c (scm_set_object_property_x &c): use the generic
3279 hashing functions and be threadsafe.
3281 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
3282 (per suggestion jaffer@gnu.ai.mit.edu).
3284 * mbstrings.c (scm_multi_byte_string): guard against argument list
3287 * strings.c (scm_make_string): loop cleanup
3289 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer

3303 functions. hash, hashq, hashv, hashx.
3305 * tags.h: made wvect an option bit of vector.

3309 * symbols.c: made the basic symbol table operations atomic.
3311 * root.c &c.: collected stack-specific global state.

3315 initialization to fix a race condition.
3317 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
3318 object, not in a global.
3319 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)

3338 Thu Feb 15 11:39:09 1996 Tom Lord <lord@beehive>
3340 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
3341 set the multi_byte flag correctly in symbols. This is wrong.
3342 intern_obbary_soft and msymbolize should take an extra parameter.
3343 Also, weird multibyte symbols don't print correctly.
3344 The weird symbol syntax is also a bit bogus (emacs doesn't quite
3347 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
3349 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
3350 use the system symhash. == #t means create an uninterned symbol.
3352 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
3354 * strings.c (scm_make_shared_substring): build'em.
3355 It might better to keep a table of these and use one
3356 less cons-pair per shared-substring.

3423 segv. (kawai@sail.t.u-tokyo.ac.jp)
3426 * lvectors.c (scm_get_lvector_hook):
3427 In guile-ii, the lvector code was broken. It was fixed in guile-iii.
3428 It seems to me like if it is broken again in guile-iv...Here is a patch.
3429 "! || (LENGTH (keyvec) == 0))"
3430 (From: Mikael Djurfeldt <mdj@nada.kth.se>)
3433 * gscm.c (gscm_sys_default_verbosity):
3434 incorrectly declared for non-__STDC__

3438 to make it easier to port to systems that use
3439 more than a single structure field to hold a descriptor.

3509 hack on elisp emulation.
3511 * dynwind.c (scm_dowinds): When entering or leaving a dynamic
