1 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5 * throw.c: Doc fixes; rearranged.
7 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
9 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
11 * acconfig.h: Added entry for PACKAGE.
12 * scmconfig.h.in: Regenerated.
14 Changes to work with automake-1.1n, which has better libtool support.
15 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
16 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
18 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
20 * Makefile.in: Rebuild.
22 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
24 * stime.c (scm_init_stime): don't define ticks/sec.
25 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
26 return value problem and is still portable.)
28 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
30 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
31 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
32 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
33 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
34 cpp_err_symbols.c): Corresponding changes.
35 * Makefile.in: Regenerated.
37 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
39 * posix.c (scm_putenv): don't check HAVE_PUTENV.
40 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
41 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
42 * putenv.c: new file, from sh-utils 1.12.
44 * posix.c (scm_environ): use malloc in place of scm_must_malloc
45 since allocation isn't for Scheme objects.
46 (scm_putenv): copy strings before placing in the environment.
48 * stime.c (scm_current_time): throw an error if time returns -1,
49 instead of returning #f.
50 (scm_get_internal_real_time, scm_get_internal_real_time): use
51 scm_long2num for return value instead of SCM_MAKINUM.
53 * stime.h: prototypes updated.
55 * stime.c (scm_time_in_msec): apparently unused, deleted.
57 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
59 * configure.in: check for gettimeofday.
61 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
62 which may be more usefully portable than a gettimeofday interface.
64 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
66 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
68 * Makefile.in: Regenerated.
70 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
72 * stime.c (filltime): recovered static procedure.
73 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
76 * posix.h: add prototype for scm_close_pipe, remove prototypes for
77 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
79 * * posix.c (scm_mknod): split the mode argument into type and perms
80 arguments, like the extra fields returned by stat.
82 * fports.c (scm_pipob): set the close, free and print procedures.
83 (scm_close_pipe): new procedure.
85 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
86 define them in boot-9.scm
88 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
90 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
91 wan't defined. Don't include fd.h.
93 * Previously fd.h was regenerated whenever configure was run,
94 forcing a couple of files to be recompiled.
96 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
97 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
98 Check for _fileno as well as _file.
100 * ioext.c: don't fd.h.
101 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
104 * Change the stratigy for getting information about errno
105 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
106 generating lists of symbols during the build process, which will
107 not always work, include comprehensive lists in the distribution.
108 To help keep the lists up to date, the "check_signals" and
109 "check_errnos" make targets can be used.
111 * configure.in: don't check for a command to extract errno codes.
112 * Makefile.am: update file lists, remove errnos.list and errnos.c
113 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
114 check_errnos targets.
115 (CLEANFILES): remove errnos.c and errnos.list, add
116 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
117 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
118 * errnos.default: deleted.
119 * cpp_signal.c: new file.
120 * cpp_errno.c: renamed from errnos_get.c.
121 * cpp_err_symbols, cpp_sig_symbols: new files.
122 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
123 * error.c (scm_init_error): #include cpp_err_symbols instead of
125 * posix.c (scm_init_posix): don't intern signal symbols. #include
128 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
130 * strop.c (scm_i_index): allow the lower bound to be equal to the
131 length of the string, so a null string doesn't always give an error.
133 * posix.h: new prototypes.
134 * posix.c (scm_status_exit_val, scm_status_term_sig,
135 scm_status_stop_sig): new functions, as in scsh. They break down
136 process status values as returned by waitpid.
138 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
140 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
141 configure doesn't know about it.
143 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
145 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
147 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
148 which defines C variables with global linkage.
150 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
152 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
155 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
157 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
158 has time to check why this doesn't work well with continuations.
160 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
162 * Fix shell syntax error; some shells won't tolerate
163 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
165 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
167 * posix.c (scm_uname): throw an error if uname fails instead
170 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
172 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
175 * async.c (scm_ints_disabled): definition moved from error.c.
177 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
179 * acconfig.h: Removed PACKAGE.
181 * scmconfig.h.in: Regenerated.
183 * snarf.h: g++ says it's non-portable not to specify the first
184 argument in a varargs declaration. I introduced the first
185 argument by using preprocessor conditionals.
187 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
189 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
190 (scm_freopen): use RO string macros for filename and modes.
191 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
193 * posix.c (scm_getgrgid): simplify conversion of name to C string.
194 (scm_mknod): use RO string macros for path.
196 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
197 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
199 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
200 use SCM_ROSTRINGP and SCM_ROCHARS.
202 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
204 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
207 * ramap.c (scm_ra_matchp, scm_ra_matchp, scm_array_fill_int, racp,
208 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
209 support for byte vectors.
211 * print.c (scm_iprin1): Limit number of vector elements printed
212 according to pstate->length.
214 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
216 * backtrace.c (scm_display_error_message): don't segv if message
219 * error.h: prototype for scm_error_scm.
221 * error.c (scm_error_scm): new procedure, reimplements scm-error
222 in C and uses scm_error.
224 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
226 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
227 pointer to the Scheme variable read-hash-procedures and intern it
228 in scm_init_read. Modify scm_read_hash_extend and
229 scm_get_hash_procedure to use the pointer.
231 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
233 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
234 (SCM_KEYWORD_STYLE): defined.
236 * read.c (scm_read_opts): add a keywords option. This isn't a
237 boolean option, in case someone wants to add support for DSSSL
239 Setup scm_keyword_prefix symbol.
240 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
242 * I've left keyword support disabled by default, since it doesn't
243 seem to break the module system and it gives R4RS standard behaviour.
244 It can be reactivated with (read-set! keywords 'prefix).
246 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
248 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
249 before constructing arbiter.
251 * eval.c (scm_m_define): Bugfix: Check that the object is a
252 closure before setting the procedure property!
254 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
256 * ports.c: Removed `ungetc-char-ready?'.
258 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
260 * read.c (scm_init_read): intitialise scm_read_hash_procedures
261 (idea from Mikael: make it a pair so scm_permanent object only
263 (scm_read_hash_extend): don't call scm_permanent_object.
264 (ideas from Mikael): if chr is already in the list, replace its
265 procedure instead of appending it again. If proc is #f, remove
267 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
269 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
271 * gdbint.c (gdb_read): update scm_lreadr usage.
273 * load.h: update prototypes.
275 * load.c (scm_primitive_load, scm_read_and_eval_x,
276 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
278 * read.h: add prototype for scm_read_hash_extend. Change args for
281 * read.c (scm_read_hash_procedures): new variable.
282 (scm_read_hash_extend): new procedure.
283 (scm_get_hash_procedure): new procedure.
284 * (scm_lreadr): use scm_get_hash_procedure instead of an argument
285 for extended # processing.
286 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
287 scm_read_token): remove case_i, sharp arguments. Change callers.
289 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
291 * read.h (SCM_N_READ_OPTIONS): increase to 3.
292 (SCM_CASE_INSENSITIVE_P): define.
294 * read.c: add case-insensitive option to scm_read_opts.
295 * (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
296 to determine whether to convert symbol case.
297 (default_case_i): definition removed.
298 * read.c (scm_read_token): if case_i, downcase ic before doing
301 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
303 * configure.in: Added configuration option `guile-debug'.
304 Configure with --enable-guile-debug if you want a bunch of extra
305 functions used for debugging when developing Guile.
307 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
309 * procs.c (make-cclo): New undocumented debugging procedure: Make
310 compiled closure with internal procedure PROC and length LENGTH.
311 Only compiled if GUILE_DEBUG is defined.
313 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
315 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
317 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
319 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
320 with 3 or more args internally to the evaluator.
322 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
324 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
325 with 3 or more args internally to the evaluator. This is mainly
326 because we don't want to pass entry and exit points of the
327 debug support twice, but it also seems to increase the speed of
328 the evaluator for such calls (e. g. (+ 1 2 3)).
330 * * backtrace.c (scm_display_application): New procedure:
331 display-application; Set fancy printing parameters individually
332 for different types of display (backtrace, error, application).
333 (These should of course be customizable!)
335 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
336 clear the CHECK-flags.
338 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
340 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
342 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
344 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
345 from pairs with a GLOC in the car.
347 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
348 otherwise `symbol-hash' will behave badly.
349 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
350 we get segmentation fault!
352 * * symbols.c: Added #include "weaks.h". New functions:
353 `builtin-bindings' and `builtin-weak-bindings'. (These will be
354 moved to an extraneous library when we split libguile.)
356 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
358 * filesys.c (scm_stat): stat now takes fport arguments too as
359 documented in the manual.
361 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
363 * debug.c (scm_single_step): Bugfix: Call continuation with
364 scm_call_continuation instead of throwing to it.
366 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
368 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
369 argument wasn't declared to be optional.
371 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
373 * stime.c (scm_init_stime): Add feature "current-time".
375 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
377 * throw.h: prototype for scm_exit_status.
378 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
379 args to derive an exit status. Allows (quit) to work from a
381 (scm_exit_status): new function.
384 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
386 * eval.c (scm_deval): Removed some old code.
387 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
389 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
392 * symbols.c (msymbolize): Bugfix: Must initialize property list to
395 * procs.c: Introduce the existent C function scm_thunk_p at the
396 Scheme level as well.
398 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
400 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
401 used from C to easily lookup the value of a symbol in the current
404 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
406 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
407 scm_init_unif in this file. This will also fix a previous problem
410 * configure.in: Added AM_MAINTAINER_MODE
412 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
414 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
417 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
419 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
420 source files that are not always included in libguile but should
421 have their dependencies calculated by automake. This variable is
422 recognized by automake, no further magic is needed.
423 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
424 to deal exclusively with *.lo files, as it seems. The *.o files
425 are built automatically when the corresponding *.lo file gets
428 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
430 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
433 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
435 * unif.c (scm_array_set_x): minor change to argument error checking.
437 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
439 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
440 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
441 They should only be included in the library at configure.in's
443 (libguile_la_LDADD): Include the appropriate .lo files here.
444 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
445 so we know when to build them (and their .lo bretheren).
446 * configure.in (LIBLOBJS): New substituted variable. We let
447 configure decide which .o files to include in LIBOBJS, and then
448 put the corresponding list of .lo files in LIBLOBJS. The latter
449 is what we pass to libtool.
450 * Makefile.in, configure: regenerated.
452 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
454 * symbols.c (scm_sysintern0): New function. Contains the core of
455 old scm_sysintern but doesn't take a second value argument.
456 (scm_sysintern): Now uses scm_sysintern0.
457 (scm_sysintern_no_module_lookup): Renamed to
458 scm_sysintern0_no_module_lookup and doesn't take a second value
461 * symbols.h (scm_sysintern0: Added declaration.
463 * options.c (scm_init_opts): Use scm_sysintern0 instead of
464 scm_sysintern when interning option keys. Otherwise we risk
465 destroying the values of already interned variables.
467 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
468 scheme-level boolean (use SCM_NFALSEP).
470 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
472 (scm_backtrace): New function. (C version of old function from
473 boot-9.scm) Motivation: Make it possible to display backtraces
474 without depending on boot-9.scm. (I'm uncertain if this
475 motivation is good enough...)
477 * root.h (scm_root_state): Add member the_last_stack_var.
478 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
480 * root.c (mark_root): Mark scm_the_last_stack_var.
482 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
485 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
487 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
488 1. mark_lazy_catch didn't mark the smob.
489 2. Both functions above have standard variants:
490 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
491 free_lazy_catch --> scm_free0.
493 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
495 * throw.c (scm_internal_lazy_catch): New function.
496 (scm_lazy_catch): Rewritten to use it.
497 (scm_ithrow): Handle the new lazy catch representation.
498 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
499 that doesn't have a jmpbuf is a lazy catch clause.
500 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
501 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
502 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
504 (scm_init_throw): Register the new lazy-catch smob type.
505 * throw.h (scm_internal_lazy_catch): decl for new function.
507 * throw.c (scm_internal_catch): Doc fixes.
509 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
510 configure.in. Including this might cause problems if applications
511 that link against libguile include their own copies of alloca, but
512 if they're using autoconf, they should be adding libguile to LIBS
513 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
514 the copy in libguile, and things will be okay. (I think.)
516 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
518 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
520 strop.h: move prototypes too.
522 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
524 * posix.c (scm_init_posix): don't intern EINTR since it's now done
527 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
528 etc. I deleted them from filesys.c long ago, but didn't
529 notice they were here too (although ineffective since
530 sys/stat.h wasn't included).
532 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
534 * eval.c: Don't define alloca in GCC case. gcc will automatically
535 use __builtin_alloca if appropriate.
537 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
539 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
540 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
541 that values of automatic variables are preserved. See comments
542 for safe_setjmp for details.
544 Change from Thomas Morgan:
545 * variable.c: Include eq.h.
546 (var_equal): New function.
547 (variable_smob): Use var_equal as the discriminator for variables.
549 * throw.c (s_throw): Remove extraneous declaration.
551 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
552 * eval.c: Add necessary CPP cruft to support that.
553 * configure, Makefile.in, scmconfig.h.in: regenerated.
555 Change from Thomas Morgan:
556 * procprop.c (scm_procedure_properties): Convert the Scheme
557 boolean returned by scm_procedure_p into a C boolean before using
558 it as a condition for SCM_ASSERT.
559 (scm_procedure_property): Likewise.
561 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
562 indications of Unixness.
565 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
567 * * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
569 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
571 * read.c (scm_lreadr): use scm_misc_error to improve one of the
572 "unknown # object" error messages.
574 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
575 (scm_i_index) and declare it static. Add a 'direction' argument
576 to indicate what way the search should go.
577 (scm_i_index): throw out-of-range error instead of wrong-type-arg
579 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
580 strop.h: remove scm_i_index, scm_i_rindex prototypes.
582 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
584 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
586 * * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
587 to avoid clash with various scsh forks.
589 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
591 The following two changes (ramap.c, throw.c) are motivated by the
592 apparent unportability of forward declarations of static arrays of
593 the form `static foo bar[];'.
595 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
596 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
598 * throw.c (scm_throw): Moved above scm_ithrow.
600 * options.h: Removed the extern declarations of scm_yes_sym and
601 scm_no_sym since these are static.
603 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
605 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
607 * Makefile.am: remove AWK=@AWK@.
608 Add a rule for generating errnos.list.
609 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
611 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
612 don't extract errnos, just set a variable (avoids the
613 need to recompile error.c just because configure is run.)
615 * unif.h: update prototypes.
616 * unif.c (scm_uniform_array_read,write): change the offset and
617 length arguments to start and end, for consistency.
619 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
621 * ioext.h: update prototypes.
622 * * ioext.c (scm_read_delimited_x): replaces scm_read_line and
623 scm_read_line_x, it's a more general procedure using an
624 interface from scsh. read-line and read-line! are now defined
626 * Note that the new read-line trims the terminator
627 by default, previously it was appended to the returned string. An
628 optional argument specifies how to process the terminator (scsh
629 compatible). For the old behaviour: (read-line port 'concat).
630 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
631 returns a pair, but is converted to multiple values if the scsh
634 socket.h: update prototypes.
635 * socket.c (scm_recvfrom): for consistency with other procedures,
636 take start and end as separate optional arguments.
637 * (scm_recv, scm_recvfrom): don't allow the second argument
638 to be a size, only a buffer. Change the scheme names to
639 recv! and recvfrom!. Don't return the buffer.
641 * ioext.h, posix.h: move prototypes too.
642 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
643 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
644 "read.h" and "unif.h".
645 * ioext.c: include "chars.h"
647 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
649 * dynl.c: The dynamic linking and module registration functions
650 are now defined even when dynamic linking is not available for the
651 host system. Some of their functionality can be done without
652 dynamic linking; when it's really needed, they throw errors.
654 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
656 * configure.in: Only define DYNAMIC_LINKING when one of the system
657 dependent functions is detected.
658 * dynl.c (scm_dynamic_func): New function to get the address of a
659 function in a dynamic object.
660 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
661 produced by scm_dynamic_func as the thing to call.
663 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
665 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
666 (scm_register_module_xxx, scm_registered_modules,
667 scm_clear_registered_modules): New functions.
669 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
671 * symbols.c (scm_sysintern): Renamed to
672 scm_sysintern_no_module_lookup.
673 (scm_sysintern): New function to take the place of the old
674 scm_sysintern. It uses the current toplevel lookup closure to give
675 the symbol its value. This is a temporary hack to put packages
676 like gtcltk into their own module.
677 (scm_can_use_top_level_lookup_closure_var): New variable to tell
678 us whether `scm_top_level_lookup_closure_var' has been initialized
680 * eval.c (scm_init_eval): Set it.
682 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
684 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
685 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
687 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
689 * (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
690 scm_sys_dup): deleted: FD capability will be added to other
692 * Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
693 scm_fd_free, fd_smob, scm_intern_fd.
694 * (scm_open): renamed from scm_sys_open. Return a port instead of
695 an FD object. Make the mode argument optional.
696 * (scm_sys_create): deleted, it's just a special case of open.
697 (scm_init_filesys): move interning of constants O_CREAT etc.,
698 here (were previously using SCM_CONST_LONG macro).
699 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
701 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
702 include "fports.h" and <stdio.h>
703 (scm_stat, scm_select): don't support FD objects.
705 * error.h: adjust scm_syserror_msg prototype.
706 * error.c (scm_syserror_msg): take an extra argument for errno.
707 Using the global value didn't always work, since it could be
708 reset by procedure calls in the message or args arguments.
710 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
711 I don't understand why the check was there (and what about the
714 * strop.c (scm_string_copy): allow shared substrings to be copied.
716 * unif.h: corresponding change to prototypes.
717 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
718 recognize two new optional arguments: offset and length. Allow
719 the port argument to be an integer (file descriptor, for scsh).
720 Include <unistd.h> for "read" prototype.
722 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
724 * socket.c: don't include filesys.h.
726 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
728 * Makefile.am: add AWK=@AWK@ (?)
730 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
732 Add a rule to generate errnos.c from errnos.
733 * error.c (scm_init_error): include errnos.c.
734 * errnos_cnvt.awk: new file, converts the list of errno codes to
736 * errnos_get.c: new file.
737 * errnos.default: new file, contains errnos to try if they can't
738 be extracted from errno.h.
739 * configure.in: if using GCC, try and extract errno codes from
743 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
745 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
746 * Makefile.am: Made libguile into a libtool library.
747 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
748 Set libtool_libs to indicate that libguile is a libtool library.
749 See guile/ChangeLog for details.
750 * .cvsignore: ignore "*.lo", the libtool library objects.
752 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
754 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
755 use htons in getservbyport argument.
757 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
759 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
760 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
763 * objprop.c (scm_object_property): No need to take the CDR of the
764 value returned by scm_object_properties, since Aug 20 change.
766 * configure.in: When checking for struct linger, #include
767 <sys/types.h> as well as <sys/socket.h>. I've never known
768 <sys/types.h> to cause any portability problems, and Solaris's
769 <sys/socket.h> needs it.
770 * configure: Rebuilt.
772 I think the Sun compiler has chosen a perverse way to interpret
773 ANSI declarations combined with K&R definitions. We'll
774 appease it a little bit. But when it invades France, we fight.
775 * print.c (scm_iprlist): Change 'tlr' argument to an int.
776 * print.h (scm_iprlist): Here too.
777 * numbers.c (scm_divbigdig): Change definition to match
778 declaration in numbers.h.
779 * unif.c (scm_makflo): Change definition to match declaration in
782 * init.c (scm_boot_guile): Don't return the value of
783 scm_boot_guile_1. This function doesn't return a value;
784 scm_boot_guile_1 doesn't return a value (or return at all).
786 * eval.c (unmemocopy): Add a semicolon to appease the Sun
789 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
790 compile. I have a feeling this function is a bad idea anyway ---
791 one should always test for features, not systems.
793 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
794 semicolons. Only pure luck kept this from being noticed earlier.
796 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
798 * socket.c (scm_recvfrom): Added missing semicolon.
800 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
802 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
803 the buffer and start and end positions for scsh networking
806 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
808 * configure.in: Revert previous change to this file; the problem
809 is due to transient automake weirdness.
810 * configure: Rebuilt.
812 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
813 PLUGIN/guile.libs. configure generates the latter from the former.
814 * Makefile.in: Rebuilt.
816 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
817 need this if we install scripts, like guile-snarf.
818 * configure: Rebuilt.
820 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
822 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
824 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
826 * socket.c (scm_addr_vector): fix faulty scm_listify.
828 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
830 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
831 style block comment is no longer considered an error.
833 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
835 * PLUGIN/guile.libs.in: New file.
836 * PLUGIN/guile.libs: Removed from repository.
837 * configure.in: Create PLUGIN/guile.libs from
838 PLUGIN/guile.libs.in. This is for including additonal libraries
839 needed for dynamic linking.
840 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
841 instead of PLUGIN/guile.libs.
843 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
845 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
847 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
848 occurrences of the given element from the list, not just the
849 first. This is how the Emacs Lisp functions behave, how the
850 analogous Common Lisp functions behave, and (I believe) how the
851 older Maclisp functions worked. I realize that this change may
852 break code, but it seemed better to break it before the Guile
855 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
856 Their prototypes were already present in gc.h, but they weren't
858 (scm_init_storage): Initialize scm_protects.
859 * root.c (scm_protects): New element of scm_sys_protects.
861 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
863 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
865 * libguile.h: Added #include "libguile/net_db.h".
867 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
868 30 change. That file is only meant for communication between the
869 configuration process and load.c. If code linked against libguile
870 wants to get at the paths mentioned in libpath.h, it can call
871 functions declared in load.h.
873 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
875 * libguile.h: Removed #include "libguile/fdsocket.h"
877 * net_db.c: Added #include <sys/socket.h>.
879 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
881 * filesys.c (scm_input_waiting_p): use select in preference to
882 FIONREAD, since the latter doesn't detect EOF.
883 Throw error if neither select nor FIONREAD available.
885 * socket.c (scm_connect): take a port, not a fd object.
886 (scm_fill_sockaddr): throw an error if fam is not recognised.
887 (scm_bind): use scm_fill_sockaddr.
888 (scm_listen): take a port, not a fd object.
889 (scm_accept): take and return a port. return #f in the car if
891 (scm_sock_fd_to_port): new procedure.
892 (scm_socket): use scm_sock_fd_to_port.
893 (scm_addr_vector): throw error if unrecognised address type.
894 take an extra argument with the calling procedure name.
895 (scm_getsockname): take a port. return #f if address can't be got.
896 (scm_getpeername): take a port. return #f if address can't be got.
897 (scm_recvfrom): take a port. return #f for address component if can't
899 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
900 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
902 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
904 * throw.c (scm_internal_catch): Make body funcs and handler funcs
905 use separate data pointers, to allow them to be designed
906 independently and reused.
907 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
908 Renamed from catch_body, catch_handler, and uncaught_throw; made
910 (struct scm_catch_body_data): Renamed from catch_body_data; moved
912 (scm_catch): Use the above.
913 (scm_throw): Don't bother printing a message for an uncaught
914 throw; we establish a default handler in init.
915 * throw.h (scm_internal_catch): Prototype updated.
916 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
918 (struct scm_body_thunk_data): New structure, used as data
919 argument to scm_body_thunk.
920 * init.c (struct main_func_closure): New structure, packaging up
921 the data to pass to the user's main function.
922 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
923 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
924 scm_internal_catch to establish a catch-all handler, using
925 scm_handle_by_message. This replaces the special-case code in
927 (invoke_main_func): Body function for scm_internal_catch; invoke
928 the user's main function, using the main_func_closure pointer to
929 decide what to pass it.
930 * root.c (struct cwdr_body_data): Remove handler_proc member.
931 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
932 (cwdr_handler): Removed.
934 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
936 * socket.h (SCM_P): update bind prototype.
937 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
939 (scm_socket): return a port, not a file descriptor object.
940 include "fports.h" and <unistd.h>
941 (scm_bind): take a port, not a file descriptor object.
942 take an extra argument for address args.
944 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
945 INADDR_NONE, INADDR_LOOPBACK.
947 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
949 * init.c: include net_db.h and not fdsocket.h.
950 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
952 * Makefile.am: corresponding changes.
953 * socket.h: renamed from fdsocket.h, fix names.
954 * net_db.h: renamed from socket.h, fix names.
955 * socket.c: renamed from fdsocket.c.
956 remove _sys from procedure names.
957 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
958 add "socket" to features list.
959 * net_db.c: renamed from socket.c.
960 remove _sys from procedure names.
961 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
962 add "net-db" to features list.
963 include "net_db.h". don't include <sys/socket.h> or
966 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
968 * tags.h (scm_tags): Removed comma at end of last enumerator.
970 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
972 Don't use GCC extensions to allocate space for debugging frames.
973 (Here he goes again! Why do we put up with this?!)
974 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
975 an scm_debug_info structure, not an in-line array of them. Add
976 'info' member, to say how many vect elements we've used, for eval
978 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
979 a new variable debug_info_end to mark the end of vect, instead of
980 the address of the 'info' pointer itself.
981 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
982 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
983 (SCM_APPLY): Explicitly allocate space for debug.vect.
984 * debug.c (scm_m_start_stack): Same, for vframe.vect.
985 * stacks.c: Adjusted for new debug frame structure.
986 (RELOC_INFO, RELOC_FRAME): New macros.
987 (stack_depth, read_frames): Use them, and new scm_debug_frame
988 element 'info', instead of magically knowing that eval frames have
989 an info pointer sitting after vect.
990 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
992 (scm_init_stacks): Formatting tweaks.
994 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
996 Give GCC more control flow information, so it can be sure that
997 variables aren't used uninitialized.
998 * error.h (scm_error, scm_syserror, scm_syserror_msg,
999 scm_sysmissing, scm_num_overflow, scm_out_of_range,
1000 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
1001 scm_misc_error): Tell GCC that these functions never return.
1002 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
1003 out the field type, call abort if SCM_ASSERT returns, to placate
1005 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
1006 scm_wta ever returns. We can't handle this case anyway, and this
1007 gives the optimizer more information.
1008 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
1009 scm_wta ever returns.
1011 In some cases, the code is fine, but GCC isn't smart enough to
1012 figure that out; this usually happens when one variable is only
1013 initialized and used when a particular condition holds true, and
1014 we know that condition will never change within a given invocation
1015 of the function. In this case, we simply initialize the variables
1016 to placate the compiler, hopefully to a value which will cause a
1017 crash if it is ever actually used.
1018 * print.c (scm_iprin1): Initialize mw_pos.
1019 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
1020 * throw.c (scm_ithrow): Initialize dynpair.
1021 * unif.c (scm_uniform_vector_ref): Initialize cra.
1022 * struct.c (init_struct): Initialize prot.
1023 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
1025 * strports.c (scm_eval_0str): Don't return uninitialized garbage
1026 if EXPR contains no expressions.
1028 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
1030 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
1031 cause an infinite loop (???). So much for the algebraic
1032 equivalency of variable-sized arrays and alloca...
1034 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
1036 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
1037 a SCM boolean, not a C boolean.
1039 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
1041 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
1042 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
1043 rules for raising scm_mtrigger. Previously, unfortunate but not
1044 unlikely circumstances could result in almost constant invokation
1045 of the gc. Now, this situations should be less likely, but they
1046 are not prevented completely.
1048 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
1050 * numbers.c (scm_fuck): Procedure removed; looks like old test
1052 * numbers.h: Prototype removed.
1054 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
1056 * debug.h (scm_debug_frame): Change `vect' member from an in-line
1057 array to a pointer, to match my Nov 21 change in eval.c.
1059 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1061 * libguile.h: Added #include "libguile/backtrace.h", #include
1062 "libguile/stacks.h".
1064 * strings.c (scm_string scm_make_string scm_string_ref
1065 scm_string_set_x scm_string_equal_p scm_string_append):
1066 Bugfix according to scm patch from Aubrey Jaffer:
1067 Corrected long-standing
1068 (not (eqv? (integer->char 128)
1069 (string-ref (make-string 1 (integer->char 128)) 0)))
1070 bug found by John Kozak <jk@noontide.demon.co.uk>.
1072 * strports.c, strports.h: Make scm_eval_0str return the value of
1073 the last expression evaluated (previously, it returned void).
1075 * strports.c, strports.h: New function: scm_read_0str. Does what
1078 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1080 * simpos.c (scm_getenv): return #f if string can't be found in the
1081 environment instead of throwing an exception, for compatibility
1082 with numerous other systems.
1084 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
1086 * Makefile.am (.c.x): Use guile-snarf.
1087 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
1089 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
1091 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1093 * backtrace.c (scm_display_error_message): Made non-static, and
1094 renamed from display_error_message.
1095 * backtrace.h (scm_display_error_message): Added extern decl.
1096 * throw.c (uncaught_throw): Use it to display the error message.
1098 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
1100 * inet_aton.c: Use #if 0, not #ifdef 0.
1102 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
1104 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
1105 to convert the returned value.
1106 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
1107 the offset argument.
1109 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1111 Add new interface to catch/throw, usable from C as well as
1113 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
1114 (scm_internal_catch): New function, replaces...
1115 (scm_catch_apply): Deleted.
1116 * throw.c (scm_catch_apply): Deleted; replaced with a more general
1117 mechanism which is a bit more code, but can be used nicely from C
1118 and implement the Scheme semantics as well.
1119 (scm_internal_catch): This is the replacement; it's named after
1120 the analogous function in Emacs.
1121 (scm_catch): Reimplemented in terms of the above.
1122 (struct catch_body_data, catch_body, catch_handler): New
1123 functions, used by scm_catch.
1124 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
1125 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
1126 support for new cwdr.
1128 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
1131 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
1133 * acconfig.h: Added DYNAMIC_LINKING symbol.
1134 * configure.in: Add option and checks for dynamic linking.
1135 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
1136 dynl.h: New files for dynamic linking support.
1137 * Makefile.am (libguile_a_SOURCES):
1139 (modinclude_HEADERS): Added "dynl.h".
1140 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
1142 * init.c (scm_boot_guile_1): Call
1143 scm_init_dynamic_linking to initialize dynamic linking support.
1145 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
1147 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
1148 (as we Schemers say). It needs to be global, so that I can tweak
1149 it for the proper operation of unexec.
1150 (scm_boot_guile_1_live): New variable, see above.
1152 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
1154 * guile-snarf.sh: Removed.
1155 * PLUGIN/guile.libs: Added dependency for -lm.
1156 * acinclude.m4: Renamed from aclocal.m4.
1157 * PLUGIN/greet: Removed.
1158 * Makefile.am, aclocal.m4: New files.
1159 * configure.in: Updated for Automake.
1161 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
1163 * eval.c (scm_definedp): Use top_level_lookup_closure_var
1164 and not top_level_lookup_thunk_var.
1166 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
1168 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
1170 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
1172 * eval.c (scm_definedp): Incompatibly changed to be a builtin
1173 Scheme function, instead of syntax. Single argument is now a
1176 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1178 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
1179 scm_ra_divide): Properly terminate statements passed as arguments
1180 to IVDEP macros. (Thanks to Bernard Urban.)
1182 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
1183 with non-constant sizes. (Thanks to Bernard Urban.)
1185 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1187 It's an "eval closure", not an "eval thunk." A thunk is a
1188 function of no arguments.
1189 * root.h (struct scm_root_state): Renamed
1190 top_level_lookup_closure_var from top_level_lookup_thunk_var.
1191 (scm_top_level_lookup_closure_var): Renamed from
1192 scm_top_level_lookup_thunk_var.
1193 * root.c (mark_root): Uses changed.
1194 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
1195 * init.c (scm_start_stack): Uses changed.
1196 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
1197 Change scheme-visible name to *top-level-lookup-closure* from
1198 *top-level-lookup-thunk*.
1200 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
1202 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
1203 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
1205 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
1207 * gc.c (struct scm_heap_seg_data): Doc fixes.
1209 * gc.c (scm_gc_sweep): Empty all segments' freelists before
1210 sweeping. Then, prepend each segment's free cells to its
1211 freelist, rather than wiping out the old value. (Thanks to Marius
1214 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
1215 scm_check_freelist, scm_debug_newcell): New functions and
1216 variables, for debugging freelist problems.
1217 * pairs.h (SCM_NEWCELL): New debugging version added.
1218 * gc.h (scm_debug_newcell): Added extern declaration, used by
1219 debugging version of SCM_NEWCELL.
1221 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1223 On some systems <libc.h> conflicts with <unistd.h>, and should not
1224 be #included at all.
1225 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
1226 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
1227 * configure.in: Call it.
1228 * posix.c, filesys.c: Use its results to decide whether or not to
1230 * configure, scmconfig.h.in: Rebuilt with autoconf and
1233 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1235 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
1236 pointer to the stdio stream before calling scm_setbuf0, so the
1237 latter will be able to retrieve it. I'm surprised this didn't
1238 segfault earlier. (Thanks to Christopher Lee.)
1240 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1242 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
1245 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1247 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
1248 number of stack narrowing specifier pairs. The first specifier in
1249 a pair controls inner border, the second the outer border. A
1250 number means cut that number of frames, a procedure object means
1251 cut until that object is found in operator position in a frame.
1253 * root.c (cwdr): Bugfix.
1255 * read.c: Recording of positions disabled by default.
1257 * procs.c (scm_closure_p): New function.
1259 * posix.c (scm_tmpnam): New function.
1261 * load.c: Added #include "throw.h".
1262 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
1265 * load.c, load.h (scm_read_and_eval_x): New function.
1267 * eval.c: Renamed debug option "deval" to "debug".
1269 (scm_eval_x): `eval!' is no longer accessible from the scheme
1270 level. Motivation: We can't allow operations which introduce
1271 glocs into the scheme level. Guile's type system can't handle
1272 these as data. Use `eval' or `read-and-eval!' as replacement.
1274 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
1275 SCM_CONSP since this is a macro!; Set vframe.prev to
1276 scm_last_debug_frame instead of 0. In this way we can look
1277 "above" the virtual start stack frame if we wish.
1278 (scm_debug_hang): New function: Useful for debugging Guile in
1279 certain tricky situations. Will probably be removed later...
1281 * debug.h: Changed semantics of debug option "backtrace". This
1282 option now only indicates whether we want automatic backtrace at
1285 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1287 * ports.c: #include "filesys.h"
1288 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
1290 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
1291 Motivation: This is system specific code which is related to file
1292 I/O. It also may use select. Added code by Gary Houston to
1293 detect presence of character in stdio buffers.
1295 * libguile.h: #include "libguile/libpath.h"
1297 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
1298 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
1299 SCM_SITE_DIR; Install libpath.h among the other include files.
1301 * load.c, load.h (scm_sys_package_data_dir): New function.
1303 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1305 * stacks.h: Bugfix: Don't use tail-array length field as stack
1306 length field! This screwed GC.
1308 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1310 * _scm.h: Added #ifndef around definition of macros min and max.
1312 * __scm.h: Added hooks for threads to plugin to in ints protection
1313 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
1314 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
1315 the main code in these macros duplicated and spread over multiple
1316 files. Renamed SCM_THREADS_SWITCHING_CODE ->
1317 SCM_THREAD_SWITCHING_CODE.
1319 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
1321 * snarf.h: New file.
1322 * guile-snarf.sh: New file.
1323 * Makefile.in (inner_h_files): Added snarf.h
1324 (ancillary, install, uninstall, distclean): Added actions for
1326 (.c.x): Use guile-snarf.
1327 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
1328 (gen_c_files): Note that these depend on guile-snarf.
1329 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
1330 now in "snarf.h". Added #include "snarf.h" to get them.
1331 * libguile.h: Added #include "snarf.h".
1332 (Patches applied and tweaked by Jim Blandy.)
1334 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1336 * socket.c: Use K&R style declaration for 'close'; the GNU coding
1337 standards suggest against providing prototypes for system
1338 functions. Thanks to Greg Troxel.
1340 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1342 * strports.c (scm_eval_0str): New function.
1343 #include "read.h", to get prototype for scm_read.
1344 * Makefile.in (strports.o): Update dependencies.
1345 * strports.h: New prototype.
1347 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
1348 scheme name from "int?" to "integer?". It seems to do the job.
1349 * numbers.h: Rename prototype too.
1350 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
1353 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
1354 scm_num_eq_p): Rename these according to R4RS conventions: call
1355 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
1356 to making libguile R4RS compliant without ice-9...
1358 * load.c (scm_sys_search_load_path): Search for files under all
1359 extensions listed in the %load-extensions variable. If FILENAME
1360 is absolute, return it unchanged, without searching the load path.
1361 (scm_loc_load_extensions): New variable, pointing to
1362 %load-extensions' value cell.
1363 (scm_init_load): Initialize it, and the value it points to.
1364 (scm_primitive_load_path): Improve error reporting.
1366 * load.c (scm_loc_load_hook): New variable, pointing to value cell
1367 of new Scheme variable %load-hook.
1368 (scm_primitive_load): Apply %load-hook to filename.
1370 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
1372 * configure.in: add tests for figuring out whether buffered data
1373 is available in a FILE structure, which is needed by char-ready.
1375 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
1378 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
1379 exceptions using misc_error instead of syserror. It seems a bit
1380 odd to throw an exception if a string can't be found in the
1381 environment, but it's consistent with open-file, stat etc.
1382 (simpos.h): remove sys_ from getenv.
1384 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
1385 occurs, throw an error instead of returning errno. Return value
1387 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1389 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1391 * filesys.c (scm_stat2scm): derive file type and permissions from
1392 the stat mode and append them to the returned vector.
1393 There isn't much overhead in doing this and it avoids the need to
1394 work with S_IRUSR et al. in Scheme.
1395 Define symbols scm_sym_regular etc.
1396 (scm_init_filesys): don't intern S_IRUSR etc.
1398 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1399 and s_primitive_load_path.
1401 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1403 * error.h: don't declare error symbols. prototype for scm_misc_error.
1405 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1408 * error.c: use SCM_SYMBOL to set up error keys.
1409 scm_misc_error: new procedure.
1411 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1413 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1414 between `#!' and `!#' is ignored.
1415 (skip_scsh_block_comment): New function.
1417 * feature.c (scm_set_program_arguments): New argument, FIRST.
1418 * feature.h: Update prototype.
1419 * init.c (scm_boot_guile_1): Pass new argument to
1420 scm_set_program_arguments.
1422 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1424 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1425 (scm_boot_guile): Call scm_set_program_arguments here, later than
1426 the old initialization.
1428 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1429 initialization procedure.
1430 - Delete in, out, err arguments; there are other perfectly good
1431 ways to override these when desired.
1432 - Delete result argument; this function shouldn't ever return.
1433 - Rename init_func argument to main_func, for less confusion.
1434 - Delete boot_cmd argument; main_func is more general.
1435 -Add 'closure' argument, to help people pass data to main_func
1436 without resorting to global variables.
1437 - Abort if reentered; don't bother returning an error code.
1438 - Call scm_init_standard_ports to set up the default/current
1439 standard ports; no need to pass them to scm_start_stack.
1440 - Remove code to evaluate the boot_cmd, and start the repl; let
1441 the user do something like that in main_func if they want.
1442 - Remove code to package up a return value; main_func can do any
1444 - Call exit (0), instead of returning.
1445 (scm_start_stack): Don't initialize the I/O ports here; that's
1446 weird. Delete in, out, err arguments. Move guts to
1447 scm_init_standard_ports, scm_stdio_to_port.
1448 (scm_init_standard_ports): New function, to set up current and
1449 default standard ports.
1450 (scm_start_stack, scm_restart_stack): Make these static.
1451 * init.h (scm_boot_guile): Adjust declaration.
1452 (scm_start_stack, scm_restart_stack): Remove externally
1453 visible declarations for these.
1454 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1456 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1457 written out several times in scm_start_stack.
1458 * fports.h: New declaration for the above.
1460 * feature.c (scm_set_program_arguments): New function.
1461 * feature.h: New declaration for the above.
1463 * ports.c: Formatting tweak.
1465 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1467 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1468 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1469 for obtaining the address of a car or cdr field. Motivation:
1470 &SCM_CXR make assumptions about the internal structure of the
1473 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1474 Motivation: see SCM_CXRLOC.
1476 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1477 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1478 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1479 Motivation: Safer use. Some other macros are defined in terms of
1480 these operations. If these are defined using the SCM_SETCXR
1481 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1482 to inefficiency and an <e1> with side-effects could potentially
1483 break. Also, these particular operations are heavily utilized in
1484 the garbage collector. In unoptimized code there will be a
1487 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1488 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
1489 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
1490 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
1491 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
1492 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1493 vports.c: Cleaned up use of pairs: Don't make any special
1494 assumptions about the internal structure of selectors and
1495 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1496 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1497 (Among other things, this change makes it easier to build Guile
1498 with certain compilers which have problems with casted lvalues.)
1500 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1502 * stacks.c: Improve selection of relevant stack frames when making
1503 a stack object. Introduce one level of indirection in the stack
1504 object to make it possible to "narrow" to a certain region of the
1505 stack. This facilitates making use of more clever algorithms (not
1506 implemented) for selecting relevant frames and gives a cleaner
1507 design since selection of frames can be done independently of
1508 extraction of frames from the real stack.
1509 (scm_stack_id): Also take #t as argument which means look at
1512 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1513 Turn n_tail into an integer directly representing current number
1514 of frames in stack. Add field tail.
1516 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1518 * debug.c (scm_make_memoized): Made it available at scheme level.
1519 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1520 SCM_NIMP before applying heavier predicates in argument checking.
1521 (scm_local_eval): Also take memoized object as argument.
1523 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1524 aren't created with zero length, but should such a strange
1525 creature suddenly turn up...
1527 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1529 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1530 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1532 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1534 * variable.c (scm_make_variable): Make the name hint optional, as
1536 (anonymous_variable_sym): Renamed from variable_sym. All uses
1539 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1540 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1541 of scm_primitive_load_path was also changed to
1542 "primitive-load-path", from "%try-load-path". Callers changed.
1543 We'd like to respect the convention that a function named
1544 "try-mumble" should behave just like the function called "mumble",
1545 but return #f instead of signalling some error.
1546 * load.h: Rename prototypes.
1548 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1550 * print.c (make_print_state, grow_print_state), print.h: Modified
1551 the print state representation: Don't use a tail array for
1552 recording of circular references. Resizing of the print state
1553 structure invalidates the print state pointer. To avoid passing
1554 around an indirect print state reference to all printing
1555 functions, we instead let the print state reference a resizable
1558 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1560 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1561 Don't crash when passed an improper list terminated by a
1562 non-immediate value.
1564 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1566 Allocate data for structures on an eight-byte boundary, as
1567 required by the tagging system.
1568 * struct.c (alloc_struct): New function.
1569 (scm_make_struct, scm_make_vtable_vtable): Call it.
1570 * struct.h (scm_struct_n_extra_words): Bump to 3.
1571 (scm_struct_i_ptr): New "field".
1572 * gc.c (scm_gc_sweep): When we need to free the data, use the
1573 information stored by alloc_struct to find the beginning of the
1574 block allocated to the structure, so we can free it.
1576 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1578 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1581 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1582 (scm_debug_info): New member: id.
1584 * stacks.c: Stacks are now represented as structs; Stacks have an
1585 id given to them by `start-stack'.
1586 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1588 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1589 Changed stack representation.
1591 * debug.c (scm_procedure_name): Try procedure property `name' for
1592 compiled closures aswell.
1594 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
1596 * eval.c: scm_i_name moved to gsubr.c
1597 (scm_m_define): Record names of all kinds of procedure
1598 objects. (Earlier, only closures were recorded.)
1600 * procprop.h: Added declaration of scm_i_name.
1602 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1603 (scm_make_gsubr): Record names of compiled closures.
1605 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1607 * debug.c, debug.h: Removed obsolete code.
1609 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1610 stacks.c: Renamed regs --> scm_contregs.
1612 * print.c (scm_free_print_state): Cleanup print state before
1613 returning it to pool. It is better to do it here than in
1614 scm_prin1 since scm_prin1 is called often.
1616 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1617 s_set_source_property_x): Check that first argument is a pair or a
1620 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1621 scm_i_line, scm_i_column and scm_i_breakpoint global.
1623 * init.c: Added #include "backtrace.h" and #include "stacks.h".
1624 (scm_boot_guile_1): Added calls to scm_init_backtrace and
1627 * debug.h: Added debug object smob declaration and macro
1630 * configure.in: Build with backtrace.o and stacks.o if debug
1633 * Makefile.in: Added entries for new files: backtrace.c,
1634 backtrace.h, stacks.c and stacks.h.
1636 * symbols.c (scm_sym2ovcell): Fixed documentation.
1638 * _scm.h (min, max): Added.
1640 * async.c: Moved `min' macro to _scm.h.
1642 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1643 SCM_BACKTRACE_INDENT.
1645 * eval.c: Added new debug options `maxdepth' and `indent'.
1647 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
1649 * print.h: Added selector SCM_PRINT_STATE.
1651 * print.c: New functions: scm_make_print_state,
1652 scm_free_print_state.
1654 * print.h: Added declarations for scm_make_print_state,
1655 scm_free_print_state.
1657 * debug.c (scm_m_start_stack): New acro.
1659 * debug.h: Small cleanup.
1661 * init.c (scm_boot_guile_1): Moved scm_init_debug below

1686 declare functions with prototypes. (Patch thanks to Marius
1689 More prototype-related changes from Marius Vollmer:
1690 * gdb_interface.h: Wrapped header file in #ifdef/#endif
1691 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
1692 * ports.h (ptobfuns): Added prototypes. This means some casting in
1694 * fports.c: Added casts for initializations, since the functions
1695 are defined to take FILE * as their stream argument, not SCM.
1696 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
1697 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
1698 to `char *str_data' to conform to prototype.
1700 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1702 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
1704 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
1706 * stime.c, stime.h: use SCM_P method.
1708 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1710 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
1711 be given at least two arguments. Insist that lst's last element
1712 be a list, but don't make any requirements of its predecessors.
1714 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1716 * eval.c (scm_nconc2last): Revert last change; there seems to be
1717 other stuff going on here.
1719 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1721 * eval.c (scm_nconc2last): Make sure that each element of lst
1722 (which is a list of argument lists, except for the tail) is a
1723 proper list, i.e., finite and terminated by '().
1725 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1727 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
1730 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
1731 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
1734 * vectors.c (scm_make_vector): Fill vectors with the undefined
1735 value, to help make Guile Scheme code more portable to other
1738 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
1739 * symbols.h, tags.h: Doc fixes.
1741 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
1743 * async.c (scm_take_signal): Doc fixes.
1745 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
1747 * numbers.c (scm_divbigint): When the remainder is zero, we don't
1748 want to subtract it from the modulus; we just want to leave it
1751 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
1753 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
1756 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
1758 * throw.c (scm_catch_apply): Finished implementation of
1761 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
1763 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
1765 (scm_init_filesys): set "i/o-extensions" feature.
1768 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
1770 * Makefile.in (root.o): Correct dependencies.
1772 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
1774 * Makefile.in: Added dependency entry for root.o.
1776 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
1777 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
1779 * init.c (scm_start_stack): Set initial root continuation number
1782 * procs.c: New function: scm_thunk_p.
1784 * procs.h: Added declarations of scm_thunk_p.
1786 * root.c: Renamed `call-with-new-root' -->
1787 `call-with-dynamic-root'.
1788 (cwdr): Removed allocation of new root state. This should be done
1789 separately by use of scm_make_root.
1790 (scm_apply_with_dynamic_root): New function: Does what it
1791 sounds like. Needed when spawning threads.
1793 * root.h: Added member last_debug_frame to root state.
1794 Added #include "libguile/debug.h"
1796 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
1797 arguments. The motivation is that code in root.c needs catch
1798 functionality, and we want to avoid code duplication.
1799 New functions: scm_catch, scm_lazy_catch. These are wrappers for
1800 scm_catch_apply. scm_lazy_catch is intended to introduce catch
1801 handlers that run without popping the stack into the dynwind
1804 * throw.h: Added prototypes for scm_catch_apply and
1807 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1809 * root.h (scm_root, scm_set_root): Decouple thread support details
1810 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
1811 SCM_SET_THREAD_LOCAL_DATA.
1813 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
1814 and tortoise scanning loop.
1816 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
1818 * Makefile.in: Rebuild dependencies.
1820 * libguile.h: #include "libguile/print.h" before "smob.h", since
1821 the latter uses the print_state structure.
1823 * throw.c (scm_ithrow): Use the correct variable when checking to
1824 see if a given element of scm_dynwinds is a valid catch.
1826 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
1827 structure, abort; don't just silently ignore the garbage.
1829 * _scm.h: #include "print.h" here, since it seems to be used just
1831 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
1832 strports.c, unif.h: Don't #include "print.h".
1834 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1836 * feature.h (scm_loc_features): Removed external declaration.
1837 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
1839 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1841 * feature.c (scm_init_feature): Added threads feature (needs to be
1842 initialized here, since features doesn't exist when
1843 scm_init_threads is called).
1845 * libguile.h: Added #include "libguile/../threads/threads.h".
1846 (This is a kludge to get thread support working. This should be
1849 * configure.in, acconfig.h: Added flags for thread support.
1851 * scmsigs.c: Define `signal' to be `pthread_signal' if using
1854 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
1855 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
1858 * _scm.h: Added conditional #include "threads.h"
1860 * __scm.h (SCM_ASYNC_TICK): Added call to macro
1861 SCM_THREADS_SWITCHING_CODE.
1863 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
1864 allocate the basic dynamic root object.
1865 (scm_boot_guile): Added call to scm_init_root.
1867 * root.c, root.h: Added root smob.
1868 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
1869 functions: Implements dynamic roots mostly according to spec in
1870 SCM manual. Main difference is that the second argument is a
1871 throw handler rather than an error "thunk".
1873 * root.h: Added declaration of scm_init_root.
1875 * root.c: Added #include "genio.h", #include "smob.h", #include
1876 "pairs.h", #include "throw.h", #include "dynwind.h", #include
1878 (scm_init_root): Added #include "root.x".
1880 * throw.c: Added #include "stackchk.h"
1881 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
1882 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
1883 can be used in scm_call_with_new_root; Added reenabling of stack
1884 checking when catching a throw.
1886 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
1888 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
1890 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
1891 element is not found, as per R4RS.
1893 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1895 * list.c: Doc fixes throughout.
1897 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1899 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
1900 declare the char * to be const. Avoids a warning in rgx.c.
1902 * ports.h: spelling fix.
1904 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
1907 * load.c (scm_sys_try_load_path): throw an error if file not found
1908 (like it says it in NEWS).
1910 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1912 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
1913 PROPS slot to '(), not #f; it's an empty alist.
1915 * throw.h, throw.c: Use SCM_P instead of #if hair.
1917 Remove special support for uncaught throws; see throw.c for
1919 * throw.c (uncaught_throw): New function.
1920 (scm_ithrow): Call uncaught_throw if we don't find a throw
1921 target; don't mess with scm_bad_throw_vcell.
1922 (scm_bad_throw_vcell): Variable deleted.
1923 (scm_init_throw): Don't initialize it.
1925 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
1928 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1930 * numbers.c (scm_istr2int): If the number is short (as most
1931 numbers are), just call scm_small_istr2int to deal with it.
1932 (scm_small_istr2int): New function, created by un-#ifdefing the
1933 non-bignum version of scm_istr2int and renaming it.
1935 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
1937 * load.c (scm_sys_try_load): don't check whether value returned
1938 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
1939 Change the Scheme name from %try-load to primitive-load.
1941 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
1942 Can avoid passing a message, allowing it to be derived in the
1943 error handler (e.g., if we want to throw to the key both from
1946 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
1948 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
1949 references now have a new appearance which is more compact and
1950 also gives a clue about what the target of the reference is.
1951 By setting parameters in the print state, more fancy printing can
1952 be achieved. This is used by the (not yet commited) backtrace
1955 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
1957 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
1960 * print.c: Added #include "struct.h". Removed function
1963 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
1964 scm_iprin1. Removed prototype for scm_prlist.
1966 * arbiters.c (prinarb),
1967 async.c (print_async),
1968 debug.c (prindebugobj, prinmemoized),
1969 eval.c (prinprom, prinmacro),
1970 filesys.c (scm_fd_print, scm_dir_print),
1972 mallocs.c (prinmalloc),
1973 numbers.c, numbers.h (scm_floprint, scm_bigprint),
1974 smob.h (scm_smobfuns),
1975 srcprop.c (prinsrcprops),
1977 unif.c, unif.h (scm_raprin1, rapr1),
1978 variable.c (prin_var): Changed argument `int writing' to
1979 `scm_print_state *pstate'.
1981 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
1982 that it will be called before scm_init_print.
1984 * print.c (scm_prin1): Print states are now allocated when calling
1985 scm_prin1 and then passed around to all printing functions as an
1986 argument. A cache `print_state_pool' enables reuse of print
1988 (scm_make_print_state): New function.
1989 (scm_iprin1): Adaption to print states.
1990 (scm_iprlist): An initial "hare and tortoise" scan brings down
1991 time complexity to O (depth * N). (Better time complexity will be
1992 achieved when the printing code is completely rewritten.)
1994 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1996 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
1997 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
1998 it gets done whether or not the cache variable has a value.
2000 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2002 Distinguish #f and ().
2003 * __scm.h: #undef SICP.
2004 * pairs.h (SCM_EOL): Delete this definition, equating it with
2006 * tags.h (SCM_EOL): Give it a new definition here; I think I found
2007 the value it used to have. Doc fixes, too.
2009 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
2011 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
2012 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
2013 Lord's implementation of structs, allowing for tail arrays as
2014 described in the manual. Also fixed some bugs. (Both the interface
2015 and the implementation should be improved.)
2017 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
2019 * print.c, print.h: Closures now print like #<procedure foo (x)>.
2020 People who whish to see the source can do `(print-enable 'source)'.
2021 Removed #ifdef DEBUG_EXTENSIONS.
2023 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2025 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
2026 integer (assuming for now accepting an integer is a good thing).
2028 * error.c, fports.c: replace use of %S in lgh_error args with %s.
2029 %S will be used instead for write'ing arguments.
2031 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
2032 asserts. fix a few other asserts.
2033 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
2034 scm_uniform_vector_ref, scm_array_set_x,
2035 scm_dimensions_to_unform_array): change args in
2036 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
2037 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
2038 scm_substring_fill_x): likewise.
2039 gsubr.c (scm_gsubr_apply): likewise.
2040 eval.c (SCM_APPLY): likewise.
2042 * eval.c (4 places): replace scm_everr with lgh_error or
2045 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
2046 scm_memory_error): new procedures.
2047 scm_everr: deleted. can use scm_wta, dropping first two args.
2048 scm_error: convert NULL subr to SCM_BOOL_F.
2050 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
2053 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
2056 * error.c, error.h: new error keys: scm_arg_type_key,
2057 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
2059 scm_wta: reimplement using lgh_error instead of scm_everr.
2061 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
2063 * gdbint.c: scm_lread now has one more argument.
2065 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
2066 scm_port_\1; Added mutator scm_set_port_filename_x (used when
2067 loading source from non-file ports, which, e. g., happens when
2068 using the Emacs interface).
2070 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
2073 * read.c: Added code for recording of positions of source code
2074 expressions; New functions: recsexpr, scm_lreadrecparen;
2075 _scm_make_srcprops --> scm_make_srcprops
2076 (scm_flush_ws): Removed updating of positions counters. This work
2077 is already done by scm_gen_getc
2079 * read.h: Added prototype for scm_lreadrecparen
2081 * print.c: Added #include "alist.h"
2083 * eval.c: Added #include "hash.h"
2085 * eq.c: Added #include "ramap.h"
2087 * options.c: Documentation fixes.
2089 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
2090 (scm_init_srcprop): Adjusted size of initial source-whash. Name
2091 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
2092 --> scm_make_srcprops
2094 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
2095 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
2096 function calls in the definition of the whash access macros.
2098 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
2100 * init.c (scm_boot_guile): Add level of indirection to
2101 scm_boot_guile_1() to ensure that stack base pointer is properly
2102 initialized. There was no guarantee that variable i was the
2103 highest/lowest variable on stack (i.e. the call frame of
2104 scm_boot_guile was not completely protected from gc).
2106 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
2108 * ports.h (scm_port_table): put back file_name, it will be used to
2109 support debugging. Undo related changes in fports.c, ioext.c,
2112 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2114 * ports.h (scm_port_table): remove file_name member for now, it seems
2116 * fports.c (scm_open_file): don't set file_name in PTAB.
2117 (prinfport): don't use file_name in PTAB.
2118 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
2119 * ports.c (scm_add_to_port_table): don't intialize file_name.
2120 (scm_port_file_name): remove for now.
2121 * gc.c (scm_gc_mark): don't mark PTAB file_name.
2123 * fports.h (scm_mkfile): prototype deleted.
2124 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
2126 * debug.c, unif.c: use scm_out_of_range instead of
2127 wta for range errors (ASSERT still needs work).
2129 * error.c, error.h (scm_out_of_range): new procedure.
2131 * error.c, error.h (scm_out_of_range_key): new key.
2133 * posix.c (scm_sync): #else was missing.
2135 * error.c, error.h: append _key to names scm_num_overflow and
2138 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
2139 of consing an empty list.
2140 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
2141 of macros, saves code and string space.
2142 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
2143 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
2144 lower case. Rename scm_syserror_m to scm_syserror_msg.
2145 error.h: prototypes for new procedures.
2147 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
2149 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
2151 * error.c, error.h: setup scm_num_overflow key.
2153 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
2154 Remove definition of SCM_OVSCM_FLOW.
2156 * fports.c (scm_open_file): use SCM_SYSERROR_M.
2158 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
2159 explicit message and args.
2161 * error.c, error.h, __scm.h: change system_error_sym to
2164 * error.c (system_error_sym): remove leading %% from the Scheme name
2167 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
2169 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2171 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
2172 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
2173 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
2174 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
2175 renamed. (These were introduced by unsupervised name
2178 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2180 * print.c: Added code for detection of circular references during
2181 printing. (init_ref_stack, grow_ref_stack): New functions. Added
2182 a hook for printing of closures (accessible via print options).
2183 This leads to a split of calls to scm_iprin1 into two classes:
2184 elementary print operations (e. g. the code which prints a smob)
2185 still use scm_iprin1 while top level calls (like scm_display) use
2186 scm_prin1. scm_prin1 begins by clearing the data structure used
2187 to record reference information.
2189 * print.h: Added declarations of scm_prin1 and scm_prlist.
2191 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
2193 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
2195 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
2197 * error.c (err_head): scm_iprin1 --> scm_prin1
2199 * debug.c: Adjusted header comment.
2203 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2205 * strerror.c: Doc fix.
2207 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2209 * gdbint.c (gdb_read): Now possible to run during GC.
2210 (unmark_port, remark_port): New functions.
2212 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
2214 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
2215 of allocating a new string object. Also, increase size by
2216 the factor 2 instead of 1.5.
2218 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
2220 * __scm.h (SCM_P): Corrected to run under traditional C.
2222 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
2225 * async.c: Calls to scm_sysintern corrected.
2227 * async.h (scm_async_clock): Redundant declaration removed.
2229 * continuations.c (scm_dynthrow): Redundant declaration removed.
2231 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
2232 Definition typos corrected.
2234 * debug.h: Missing declarations of functions in debug.c added
2237 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2238 Missing declarations to functions in eval.c added.
2240 * filesys.c: Possibly uninitialized variable rv.
2242 * gc.h (scm_object_addr, scm_unhash_name): Missing
2243 declarations of functions defined in gc.c added.
2245 * genio.c: Possible typos str_data -> wstr_data. ???
2247 * genio.c: Possibly unintended shadowing of local variable
2248 `int c' (gotos out of scope of inner `c'). ???
2250 * init.c: Uninitialized `SCM last' may be used.
2252 * ioext.h: (scm_sys_isatty_p): Typo.
2254 * list.h (scm_list_head): Missing prototype for function in
2257 * numbers.c (scm_two_doubles): Changed from extern to static
2258 (is used only within numbers.c).
2260 * numbers.h: Repeated declarations removed.
2262 * ports.h (scm_close_all_ports_except): Declaration for the
2263 function defined in ports.c added.
2265 * posix.h: Missing declarations added.
2267 * procs.h (scm_make_subr_opt): Missing declaration added.
2269 * socket.h (scm_sys_gethost): Missing declaration added.
2271 * socket.h: Redundant declarations removed (they are in fdsocket.h).
2273 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
2274 Missing declarations added.
2276 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
2278 * struct.c: Uninitialized variable `SCM answer' may be used.
2280 * unif.c (l2ra): Declaration prototype.
2282 * unif.c (scm_array_equal_p): Dummy definition removed (it is
2283 defined in ramap.c).
2285 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
2286 Redundant declarations removed (they are in ramap.h).
2288 * variable.h (scm_make_udvariable,
2289 scm_make_undefined_variable): Declaration corrected to
2290 correspond variable.c.
2292 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
2293 Missing declarations added.
2295 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
2297 * Makefile.in (distclean): Don't forget to delete fd.h.
2299 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2301 * fd.h.in, tags.h: Trivial cleanups.
2303 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
2304 marksweep.h just declared functions from gc.c.
2305 * gc.h, libguile.h: Don't #include "marksweep.h".
2306 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2307 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
2308 dependencies updated.
2310 * libguile.h: Don't #include "files.h"; it's been deleted.
2312 * files.c (scm_sys_delete_file): Moved to filesys.c.
2313 File is now empty; deleted.
2315 * filesys.c: scm_sys_delete_file is now here. Remove
2316 #if's; they seem to rely on remnants of an old portability
2317 regimen. If the problems come up again, solve them properly,
2318 using autoconf. Specifically: Don't test M_SYSV, and #define
2319 remove to be unlink if it's #defined; don't use remove just
2320 because HAVE_STDC_HEADERS is #defined.
2321 * filesys.h: Add declarations for scm_sys_delete_file.
2322 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2323 files.o, files.h, files.c, and files.x.
2324 * init.c: Don't #include "files.h", and don't call scm_init_files.
2326 Use SCM_P instead of PROTO; the latter intrudes on the user's
2328 * params.h: Deleted; definition of SCM_P moved to...
2329 * __scm.h: ... here, where it replaces PROTO macro.
2330 * libguile.h, smob.h: Don't #include "params.h".
2331 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
2332 smob.h: Fix prototypes accordingly.
2333 * Makefile.in: Update dependencies.
2334 (inner_h_files): Remove params.h.
2336 * gc.c: #include "gc.h"; every module should include its header,
2337 to let the compiler cross-check the declarations against the
2340 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2341 simpos.h: #include "libguile/__scm.h".
2343 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2345 * init.c: Don't forget to #include smob.h and init.h.
2346 * Makefile.in: Dependencies updated.
2348 * smob.h: Use PROTO instead of #if __STDC__.
2350 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2352 * __scm.h: Doc fixes.
2354 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2355 <angles>; this allows `make depends' to work properly.
2357 * libguile.h: #include smob.h and pairs.h before the others; they
2358 define typedefs used by other headers.
2360 C files should #include only the header files they need, not
2361 libguile.h (which #includes all the header files); the pointless
2362 recompilation was wasting my time.
2363 * Makefile.in (all .o dependency lists): Regenerated.
2364 * libguile.h: Don't try to get a definition for size_t here...
2365 * __scm.h: Do it here.
2366 * _scm.h: Since this is the internal libguile header, put things
2367 here that all (or a majority) of the libguile files will want.
2368 Don't #include <libguile.h> here; that generates dependencies on
2369 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2370 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2371 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

2468 * weaks.c: Get "weaks.h".
2470 * stackchk.h: #include "libguile/debug.h",
2472 * print.h, read.h: #include "options.h", since everyone who uses
2473 either of these files will need that.
2475 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2476 anyone who uses this file will need them to define the smob
2477 printing functions. Also, get markers.h, since people will need
2478 to #define the mark functions.
2480 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2481 * ports.h: ... to here.
2483 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2484 don't rely on archaic C default type rules.
2486 * fports.h: #include "libguile/ports.h", since you need that in
2487 order to parse this.
2489 * genio.h: #include "libguile/print.h", because you need that to
2490 parse this; don't bother #including "ports.h", since print.h gets
2493 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2495 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2496 this; it's now a reference to an element of *scm_root.
2498 * debug.h: Don't #include "options.h"; the compiler won't be able
2499 to find that once the headers are installed; instead, #include
2500 "libguile/options.h".
2501 * gc.h: Same, with marksweep.h.
2502 * mbstrings.h: Same, with symbols.h.
2503 * scmhob.h: Same, with _scm.h.
2504 * smob.h: Same, with params.h.
2506 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2507 C files; there's no need for this, and it forces recompilations
2510 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2512 * error.c (scm_error): declare scm_error_callback.
2514 * error.h: prototype for scm_error_callback.
2516 * __scm.h: define lgh_error.
2517 (SCM_SYSERROR): redefine using lgh_error.
2519 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2521 * error.c (scm_error): new procedure.
2523 * error.h: prototype for scm_error.
2525 * Makefile.in (install): install scmconfig.h from the current
2526 directory, not $(srcdir).
2528 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2530 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2531 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2532 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

2538 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2539 vports.h, weaks.h: #include "libguile/__scm.h", not
2540 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2541 dependencies are within libguile properly.
2543 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2545 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2546 when scmconfig.h doesn't exist.
2548 * load.c (scm_sys_try_load): Correct spelling.
2550 * feature.c (scm_loc_features): Make this static.
2552 * Makefile.in (libpath.h): Omit trailing slash from path. We
2553 shouldn't require it of users, so why put it here?
2555 Move code to initialize and search %load-path from ice-9 to C
2556 code, so we can use the load-path to find the ice-9 boot code;
2557 this makes it easier to run Guile without installing it. See
2558 corresponding changes in guile/Makefile.in.
2559 * feature.c: Move stuff concerned with the load path to load.c.
2560 (scm_compiled_library_path): Deleted.
2561 Don't #include libpath.h here.
2562 * feature.h: Don't mention scm_compiled_library_path.
2563 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2564 <sys/stat.h>, and <unistd.h> (if present).
2565 (R_OK): #define if the system hasn't deigned to.
2566 (scm_loc_load_path): New variable.
2567 (scm_init_load_path, scm_sys_search_load_path,
2568 scm_sys_try_load_path): New functions.
2569 (scm_init_load): Initialize scm_loc_load_path to point to the
2570 value cell of the Scheme %load-path variable.
2571 * load.h: Add declarations for scm_sys_search_load_path,
2572 scm_sys_try_load_path.
2573 * init.c: Call scm_init_load_path.
2574 * Makefile.in (feature.o, load.o): Dependencies updated.
2576 * load.c, load.h: Rewrite using PROTO macro.
2578 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2580 * gc.c (scm_cellp): New function: C predicate to determine if an
2581 SCM value can be regarded as a pointer to a cell on the heap.
2583 * gc.h: Added declaration of scm_cellp.
2585 * gdb_interface.h: New file: The GDB interface header from the GDB
2588 * gdbint.c: New file: GDB interface.
2590 * gdbint.h: New file: GDB interface.
2592 * libguile.h: Added #include <libguile/gdbint.h>.
2594 * init.c (scm_boot_guile): Added scm_init_gdbint.
2596 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2597 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2598 found if object files and source are kept separate).
2600 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2602 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2604 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2606 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2607 TK_SRC_DIR; they're not relevant any more.
2609 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2610 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2612 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2614 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2615 search path, so we can find the <libguile/MUMBLE.h> headers.
2617 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2619 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2620 implicit in the .c.o rule.
2621 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2624 Put the library path in a header file, instead of passing it on
2625 the command line in every compilation.
2626 * Makefile.in (libpath.h): New target.
2627 (feature.o): Depend on libpath.h.
2628 (clean): Delete libpath.h.
2629 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2630 * feature.c: ... #include "libpath.h" here.
2631 * .cvsignore: Ignore libpath.h.
2633 Don't install the unwashed masses of Guile header files in the
2634 main #include path; put most of them in a subdirectory called
2635 'libguile'. This avoids naming conflicts between Guile header
2636 files and system header files (of which there were a few).
2637 * Makefile.in (pkgincludedir): Deleted.
2638 (innerincludedir): New variable; this and $(includedir) are enough.
2639 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
2640 (installed_h_files): Divide this up. Now this variable lists
2641 those header files which should go into $(includedir) (i.e. appear
2642 directly in the #include path), and ...
2643 (inner_h_files): ... this new variable says which files appear in
2644 a subdirectory, and are referred to as <libguile/mumble.h>.
2645 (h_files): List them both.
2646 (install): Create innerincludedir, not pkgincludedir. Put
2647 the installed_h_files and inner_h_files in their proper places.
2648 (uninstall): Corresponding changes.
2649 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2650 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2651 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
2652 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
2653 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
2654 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2655 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2656 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2657 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2658 vports.h, weaks.h: Find __scm.h in its new location.
2659 * __scm.h: Find scmconfig.h and tags.h in their new locations
2660 (they're both "inner" files).
2662 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
2664 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
2666 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2668 * posix.c: Doc fixes.
2670 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
2672 * socket.c: Don't include a prototype for inet_aton; just use a
2673 K&R style declaration, to avoid warnings but minimize the chance
2674 of conflicts with the system.
2676 On NextStep, <utime.h> doesn't define struct utime, unless we
2677 #define _POSIX_SOURCE before #including it.
2678 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
2679 * acconfig.h: New comment text for above CPP symbol.
2680 * configure.in: Call it.
2681 * posix.c: #define _POSIX_SOURCE if it seems necessary.
2683 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
2685 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
2686 testing for __EMX__.
2688 * posix.c: #include <libc.h>, if it exists.
2690 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
2691 don't even know if the latter exists.
2693 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
2694 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
2695 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
2697 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
2699 (scm_init_posix): Use them when initializing the Scheme constants
2702 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2704 * Makefile.in (libdir, includedir, bindir): Use the
2705 autoconf-supplied values, instead of deriving them ourselves.
2706 (pkgincludedir, datadir, pkgdatadir): New variables.
2707 (install, uninstall): Put the header files in a special
2708 subdirectory, not in the main search path.
2710 * Makefile.in (ALL_CFLAGS): Provide the proper value for
2711 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
2713 * Makefile.in (IMPLPATH): Deleted; never used.
2715 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
2716 on the Tcl/Tk source any more.
2717 (INCLUDE_CFLAGS): Remove references to the above.
2719 * Makefile.in (version.o): Corrected dependencies.
2721 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
2723 * libguile.h: #include "version.h"
2725 * init.c (scm_boot_guile): Call scm_init_version.
2726 * gscm.c (gscm_run_scm): Call scm_init_version.
2728 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
2729 GUILE_VERSION): AC_DEFINE these.
2730 (acconfig.h): #undef the above symbols.
2732 * Makefile.in (libobjs): Add version.o.
2733 (installed_h_files): Add version.h.
2734 (c_files): Add version.c.
2735 (gen_c_files): Add version.x.
2736 (version.o): New rule.
2737 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
2738 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

2747 weaks.o): Add version.h to dependency lists.
2748 (markers.o): Remove duplicate rule.

2752 * version.c: New file.
2754 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2756 * symbols.c (scm_strhash): scm_downcase is now a function, not an
2757 array; use it appropriately. Since GCC is quite happy to
2758 subscript functions, it never warned us about this; we should use
2759 -Wpointer-arith in the future. I guess we never tested
2762 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2764 * socket.c: Doc and copyright fixes.
2766 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2768 * debug.c: Fixed and improved gdb support.
2770 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2772 * socket.c: Added declaration of inet_aton to avoid compiler
2773 warning. (Hope this solution is correct.)
2775 * stime.c: Added declaration of ftime. (This is missing in
2778 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
2780 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2782 * Makefile.in (c_files): add strerror.c.
2784 * strerror.c: new file from Emacs' sysdep.c.
2785 maybe configure should also check for sys_errlist.
2787 * configure.in (AC_REPLACE_FUNCS): add strerror.
2789 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2791 * debug.c (scm_init_debug): Added initialization for
2792 scm_evaluator_traps.
2794 * debug.h, debug.c: Various name changes.
2795 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
2796 "debug-options-interface". See commentary in options.c.
2798 * options.h, options.c: Options now have documentation strings.
2799 Also added a long explanatory commentary.
2801 * eval.c, print.h, print.c, read.h, read.c: Modifications to
2804 * gscm.c, init.c, root.c, throw.c: Bug fixes:
2805 last_debug_info_frame is now updated in all cases.
2807 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
2810 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2812 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
2813 Added option STACK_CHECKING.
2815 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
2817 * Makefile.in: Added {debug,options,srcprop}.{h,c}
2819 * __scm.h: Removed symbols for debugging support.
2821 * acconfig.h: Added symbols for debugging support.
2823 * configure.in: Added user option for debugging support.
2824 --enable-debug will include the debugging code into libguile.a.
2826 * continuations.c (scm_make_cont): Enlarged the #if 0 around
2827 scm_relocate_chunk_to_heap.
2829 * debug.c: New file: low-level debugging support. It also
2830 includes support for debugging with gdb. (The extensions to gdb
2831 are written by Per Bothner at Cygnus.)
2833 * debug.h: New file: low-level debugging support.
2835 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
2836 argument pairs. Extensive modifications to the debugging
2837 evaluator. Added "SECTION:" commentaries to clarify what happens
2838 when, during double compilation. Renamed EVALIMP --> EVALIM.
2839 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
2840 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
2841 the beginning of the file. New procedure: scm_unmemocopy.
2842 Added some global state variables needed by the debugging
2843 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
2844 check_entry, check_apply, check_exit, debug_options and
2845 evaluator_traps. New acro: undefine.
2847 * eval.h: Renamed EVAL --> XEVAL.
2849 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
2850 --> scm_make_weak_key_hash_table.
2852 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
2853 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
2855 * libguile.h: Conditionally include debug.h
2857 * objprop.c (scm_object_properties, scm_set_object_properties_x):
2858 scm_object_properties shouldn't return handle. `handle' now gets
2859 initialized in scm_set_object_properties_x. scm_object_properties
2860 doesn't any longer create an entry in scm_object_whash.
2862 * options.c: New file: handling of run time options.
2864 * options.h: New file: handling of run time options.
2866 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
2868 * print.c: New procedure: scm_print_options
2870 * print.h: Defines for print options.

2887 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2889 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
2891 * libguile.h: #include "objprop.h"; I guess this was forgotten.
2893 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
2894 and should be called by the final client.
2896 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
2898 * gc.h: Use the PROTO macro when declaring functions.
2899 * gc.c: Use the PROTO macro when declaring static functions.
2900 Remove the CPP hair around function definitions.
2902 * gc.c (scm_init_storage): Initialize scm_asyncs.
2904 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
2905 preprocessor symbol; "__scm.h" is where it might get #defined.
2906 * __scm.h: Similar: #include <scmconfig.h> before testing
2909 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
2911 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
2913 * init.c (scm_boot_guile): Add init_func argument; call
2914 (*init_func) instead of calling scm_appinit; it's ucky to
2915 hard-code names for the user's procedures.
2916 * init.h (scm_boot_guile): Adjust declaration.
2918 * __scm.h (PROTO): New macro, for declaring functions with
2921 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
2922 eliminate all the __STDC__ conditionals.
2923 (scm_boot_guile): Add declaration.
2924 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
2925 Remove __STDC__ conditionals around function definitions; the
2926 declarations in init.h will provide the same information, more
2929 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
2930 complain about it in the error message; the error message is
2931 adequate without that note, and there's nothing the user can do
2934 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
2936 * Makefile.in (ancillary): Drop def.sed.
2938 * posix.c (scm_init_posix): Use numeric values, rather than
2939 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
2940 F_OK. The symbols aren't available on some systems, and I'm
2941 pretty sure their values are fixed by common widespread practice.
2942 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
2944 More functions unavailable on some systems.
2945 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
2946 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
2948 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2949 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
2950 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
2951 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
2952 stub that signals an error as the #else.
2954 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
2956 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
2958 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
2960 * unif.c: include ramap.h.
2962 * read.c (endif): case_insensative_p renamed case_insensitive_p.
2964 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
2966 * ports.c: include sys/ioctl.h.
2968 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
2970 * configure.in: check for sys/ioctl.h.
2972 * ports.c: include <malloc.h> not "malloc.h".
2974 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2976 * fports.c: remove ttyname and tmpnam declarations.
2978 * posix.c: fewer ttyname declarations.
2980 * fports.c: include <string.h> not "string.h".
2982 * init.c, ioext.c: include string.h and unistd.h.
2984 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2986 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
2987 genio.c, simpos.c, vports.c: include string.h.
2989 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
2991 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
2993 (scm_addr_buffer_size): change type from scm_sizet to int.
2994 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
2995 from scm_sizet to int.
2997 * error.c: include unistd.h.
2999 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
3002 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
3004 * __scm.hd, def.sed: deleted.
3006 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
3008 Changes for NeXT, suggested by Robert Brown.
3009 * configure.in: Call AC_TYPE_MODE_T.
3010 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
3011 NeXT. Put header file list in alphabetical order.
3012 * configure, scmconfig.h.in: Regenerated.
3013 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
3015 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
3018 * acconfig.h: New file, providing documentation for the CPP
3019 symbols defined in configure.in
3020 * acconfig-1.5.h: Removed; superceded by the above.
3022 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
3024 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
3026 * fports.c (scm_open_file): don't return #f, throw error.
3028 * ioext.c (fileno): renamed from %fileno.
3029 (soft-fileno): deleted.
3031 * ports.c (scm_port_revealed): don't need to check for -1 from
3033 (scm_set_port_revealed_x): return unspecified, not #f.
3035 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
3037 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
3039 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
3041 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
3043 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3045 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
3046 This is necessary on Ultrix, and doesn't hurt portability.
3048 * Makefile.in (dist-dir): New target, implementing a new dist system.
3049 (installed_h_files): Put in alphabetical order.
3050 Remove duplicate entries for markers.h and unif.h.
3051 (c_files): Remove duplicate entries for markers.c.
3052 (ancillary): Renamed from anillery; all uses changed. Remove
3053 PLUGIN; it's a directory, and needs special treatment in dist-dir.
3054 Remove all the ../doc/* files; doc/Makefile.in handles that.
3056 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
3058 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
3059 every if must have an else, or else the whole command has a
3060 non-zero exit code whenever the if's condition is false.
3062 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
3064 * posix.c: include string.h.
3066 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
3068 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
3071 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
3072 Remove leading % from scheme names.
3073 Do not return error values, call SCM_SYSERROR or similar.
3075 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
3077 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
3079 * struct.c (scm_init_struct): new file.
3081 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
3083 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
3084 (scm_list_head): added list-head for rapidly chopping argument
3085 lists off of longer lists (and similar).

3089 * objprop.c (scm_object_property): assq the cdr of the whash
3090 handle for obj, not the handle itself.
3092 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
3094 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
3095 weak hash tables last of all marking to avoid an obscure gc bug.
3096 WARNING: circular lists stored in a weak hash table will hose us.
3098 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
3100 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
3101 new functions similar to scm_substring_move_left_x and
3102 scm_substring_move_right_x.
3104 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
3106 * init.c (scm_boot_guile): prevent gc with scm_block_gc not

3111 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
3113 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
3115 * strports.c (scm_strprint_obj): convenience function. C for
3116 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
3118 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
3119 removed to a separate library
3121 * init.c (scm_boot_guile): copied from guile-tcl.c.
3122 Initialization specific to tcl interpreters removed.
3124 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
3126 * ports.c (scm_ports_prehistory): size malloced here doesn't
3127 matter so long as it is non-0 (got rid of "* 4").
3129 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
3131 * gscm.h: gscm_mkarray eliminated (presumably was not being used
3132 since its definition was bogus).
3134 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
3136 * mallocs.[ch]: back again (for rx at least).
3138 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
3140 * ports.c: removed functions relating to the mapping between ports
3141 and descriptors. (That stuff is unix-specific and should be collected
3142 in a separate library).
3144 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
3145 (Tom Mckay@avanticorp.com)
3147 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
3149 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
3150 handled correctly (SCM_FREEP was applied to them) -- test for
3151 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
3152 being overwritten with #f. (brown@grettir.bibliotech.com)
3154 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
3156 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs

3159 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
3161 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak

3166 * list.c (scm_last_pair): map '()=>'()
3168 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>

3171 Generalized assoc and hash-table functions.
3172 Factored pairs.c into multiple files.
3174 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
3176 * gscm.c (gscm_run_scm): got rid of objprop.
3178 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>

3184 NOTE: don't use a alist here.
3185 (scm_set_procedure_properties_x): fix type checking throughout this file.

3195 * vports.c (scm_make_soft_port): allocate a port table entry
3196 (possibly triggering gc) before setting the tag of the corresponding
3199 * pairs.c (scm_delq_x): never throw an error.
3201 * vectors.c (scm_make_vector): made the default vector fill argument
3202 into '() (much more useful than the previous value, "#unspecified")
3204 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
3206 * ports.c (scm_add_to_port_table): Added fields
3207 to port table entries: file_name, line_num, col.
3208 Update these in open_file, gen_getc and gen_ungetc.
3209 Added procedures to access those fields.
3211 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
3213 * procs.c (scm_make_subr_opt): new entry point for making
3216 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
3218 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.

3222 * numbers.c (scm_exact_p): This function no longer
3223 implements "integer?".

3227 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
3228 (scm_gc_stats): return an assoc of useful data. Replaces "room"
3229 and the stats reporting formerlly built into repl.

3232 GC statistics keeping moved to gc.c.
3233 Other statistics keeping can be done from Scheme.
3234 REPLS are now written in Scheme.

3243 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
3245 * feature.c (scm_compiled_library_path): moved here from repl.c.
3246 This file is for stuff relating specifically to Scheme libraries
3249 * eval.c (scm_m_define): don't give warning about redefinition, don't
3252 NOTE: this should throw a resumable exception with parameters --
3253 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
3255 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
3257 * error.c: scm_warn eliminated.

3269 between the call to procedurep and use.
3271 * error.c (scm_everr):
3273 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
3276 * strports.c: don't reveal the port's string to the caller
3277 because it changes size.
3279 (stputc stwrite): check/change the strings length with interrupts
3282 * objprop.c (scm_set_object_property_x &c): use the generic
3283 hashing functions and be threadsafe.
3285 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
3286 (per suggestion jaffer@gnu.ai.mit.edu).
3288 * mbstrings.c (scm_multi_byte_string): guard against argument list
3291 * strings.c (scm_make_string): loop cleanup
3293 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer

3307 functions. hash, hashq, hashv, hashx.
3309 * tags.h: made wvect an option bit of vector.

3313 * symbols.c: made the basic symbol table operations atomic.
3315 * root.c &c.: collected stack-specific global state.

3319 initialization to fix a race condition.
3321 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
3322 object, not in a global.
3323 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)

3340 * async.c: New support for interrupt handlers.
3342 Thu Feb 15 11:39:09 1996 Tom Lord <lord@beehive>
3344 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
3345 set the multi_byte flag correctly in symbols. This is wrong.
3346 intern_obbary_soft and msymbolize should take an extra parameter.
3347 Also, weird multibyte symbols don't print correctly.
3348 The weird symbol syntax is also a bit bogus (emacs doesn't quite
3351 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
3353 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
3354 use the system symhash. == #t means create an uninterned symbol.
3356 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
3358 * strings.c (scm_make_shared_substring): build'em.
3359 It might better to keep a table of these and use one
3360 less cons-pair per shared-substring.
3362 Tue Feb 6 17:45:21 1996 Tom Lord <lord@beehive>
3364 * strings.c (scm_string_shared_substring): create shared

3421 (kawai@sail.t.u-tokyo.ac.jp)
3423 * gscm.c (gscm_set_procedure_properties_x): parameter "new" => "new_val"
3424 for C++. (Seth Alves <alves@gryphon.com>)
3426 (gscm_cstr): uses an uninitialized local variable causing
3427 segv. (kawai@sail.t.u-tokyo.ac.jp)
3430 * lvectors.c (scm_get_lvector_hook):
3431 In guile-ii, the lvector code was broken. It was fixed in guile-iii.
3432 It seems to me like if it is broken again in guile-iv...Here is a patch.

3438 incorrectly declared for non-__STDC__
3439 (Tom_Mckay@avanticorp.com)
3441 * ports.c (scm_setfileno): Tweak the macro a bit
3442 to make it easier to port to systems that use
3443 more than a single structure field to hold a descriptor.
3445 * debug.c (change_mode): Avoid GNUCism "int foo[n];"

3525 * eval.c (SCM_CEVAL): if the function position evaluates
3526 to a macro, process it accordingly. (Previously, macros were
