1 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
3 * stime.c (scm_init_stime): don't define ticks/sec.
4 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5 return value problem and is still portable.)
7 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
9 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
10 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
11 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
12 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
13 cpp_err_symbols.c): Corresponding changes.
14 * Makefile.in: Regenerated.
16 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
18 * posix.c (scm_putenv): don't check HAVE_PUTENV.
19 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
20 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
21 * putenv.c: new file, from sh-utils 1.12.
23 * posix.c (scm_environ): use malloc in place of scm_must_malloc
24 since allocation isn't for Scheme objects.
25 (scm_putenv): copy strings before placing in the environment.
27 * stime.c (scm_current_time): throw an error if time returns -1,
28 instead of returning #f.
29 (scm_get_internal_real_time, scm_get_internal_real_time): use
30 scm_long2num for return value instead of SCM_MAKINUM.
32 * stime.h: prototypes updated.
34 * stime.c (scm_time_in_msec): apparently unused, deleted.
36 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
38 * configure.in: check for gettimeofday.
40 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
41 which may be more usefully portable than a gettimeofday interface.
43 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
45 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
47 * Makefile.in: Regenerated.
49 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
51 * stime.c (filltime): recovered static procedure.
52 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
55 * posix.h: add prototype for scm_close_pipe, remove prototypes for
56 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
58 * * posix.c (scm_mknod): split the mode argument into type and perms
59 arguments, like the extra fields returned by stat.
61 * fports.c (scm_pipob): set the close, free and print procedures.
62 (scm_close_pipe): new procedure.
64 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
65 define them in boot-9.scm
67 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
69 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
70 wan't defined. Don't include fd.h.
72 * Previously fd.h was regenerated whenever configure was run,
73 forcing a couple of files to be recompiled.
75 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
76 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
77 Check for _fileno as well as _file.
79 * ioext.c: don't fd.h.
80 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
83 * Change the stratigy for getting information about errno
84 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
85 generating lists of symbols during the build process, which will
86 not always work, include comprehensive lists in the distribution.
87 To help keep the lists up to date, the "check_signals" and
88 "check_errnos" make targets can be used.
90 * configure.in: don't check for a command to extract errno codes.
91 * Makefile.am: update file lists, remove errnos.list and errnos.c
92 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
94 (CLEANFILES): remove errnos.c and errnos.list, add
95 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
96 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
97 * errnos.default: deleted.
98 * cpp_signal.c: new file.
99 * cpp_errno.c: renamed from errnos_get.c.
100 * cpp_err_symbols, cpp_sig_symbols: new files.
101 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
102 * error.c (scm_init_error): #include cpp_err_symbols instead of
104 * posix.c (scm_init_posix): don't intern signal symbols. #include
107 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
109 * strop.c (scm_i_index): allow the lower bound to be equal to the
110 length of the string, so a null string doesn't always give an error.
112 * posix.h: new prototypes.
113 * posix.c (scm_status_exit_val, scm_status_term_sig,
114 scm_status_stop_sig): new functions, as in scsh. They break down
115 process status values as returned by waitpid.
117 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
119 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
120 configure doesn't know about it.
122 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
124 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
126 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
127 which defines C variables with global linkage.
129 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
131 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
134 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
136 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
137 has time to check why this doesn't work well with continuations.
139 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
141 * Fix shell syntax error; some shells won't tolerate
142 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
144 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
146 * posix.c (scm_uname): throw an error if uname fails instead
149 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
151 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
154 * async.c (scm_ints_disabled): definition moved from error.c.
156 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
158 * acconfig.h: Removed PACKAGE.
160 * scmconfig.h.in: Regenerated.
162 * snarf.h: g++ says it's non-portable not to specify the first
163 argument in a varargs declaration. I introduced the first
164 argument by using preprocessor conditionals.
166 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
168 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
169 (scm_freopen): use RO string macros for filename and modes.
170 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
172 * posix.c (scm_getgrgid): simplify conversion of name to C string.
173 (scm_mknod): use RO string macros for path.
175 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
176 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
178 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
179 use SCM_ROSTRINGP and SCM_ROCHARS.
181 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
183 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
186 * ramap.c (scm_ra_matchp, scm_ra_matchp, scm_array_fill_int, racp,
187 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
188 support for byte vectors.
190 * print.c (scm_iprin1): Limit number of vector elements printed
191 according to pstate->length.
193 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
195 * backtrace.c (scm_display_error_message): don't segv if message
198 * error.h: prototype for scm_error_scm.
200 * error.c (scm_error_scm): new procedure, reimplements scm-error
201 in C and uses scm_error.
203 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
205 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
206 pointer to the Scheme variable read-hash-procedures and intern it
207 in scm_init_read. Modify scm_read_hash_extend and
208 scm_get_hash_procedure to use the pointer.
210 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
212 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
213 (SCM_KEYWORD_STYLE): defined.
215 * read.c (scm_read_opts): add a keywords option. This isn't a
216 boolean option, in case someone wants to add support for DSSSL
218 Setup scm_keyword_prefix symbol.
219 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
221 * I've left keyword support disabled by default, since it doesn't
222 seem to break the module system and it gives R4RS standard behaviour.
223 It can be reactivated with (read-set! keywords 'prefix).
225 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
227 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
228 before constructing arbiter.
230 * eval.c (scm_m_define): Bugfix: Check that the object is a
231 closure before setting the procedure property!
233 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
235 * ports.c: Removed `ungetc-char-ready?'.
237 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
239 * read.c (scm_init_read): intitialise scm_read_hash_procedures
240 (idea from Mikael: make it a pair so scm_permanent object only
242 (scm_read_hash_extend): don't call scm_permanent_object.
243 (ideas from Mikael): if chr is already in the list, replace its
244 procedure instead of appending it again. If proc is #f, remove
246 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
248 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
250 * gdbint.c (gdb_read): update scm_lreadr usage.
252 * load.h: update prototypes.
254 * load.c (scm_primitive_load, scm_read_and_eval_x,
255 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
257 * read.h: add prototype for scm_read_hash_extend. Change args for
260 * read.c (scm_read_hash_procedures): new variable.
261 (scm_read_hash_extend): new procedure.
262 (scm_get_hash_procedure): new procedure.
263 * (scm_lreadr): use scm_get_hash_procedure instead of an argument
264 for extended # processing.
265 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
266 scm_read_token): remove case_i, sharp arguments. Change callers.
268 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
270 * read.h (SCM_N_READ_OPTIONS): increase to 3.
271 (SCM_CASE_INSENSITIVE_P): define.
273 * read.c: add case-insensitive option to scm_read_opts.
274 * (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
275 to determine whether to convert symbol case.
276 (default_case_i): definition removed.
277 * read.c (scm_read_token): if case_i, downcase ic before doing
280 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
282 * configure.in: Added configuration option `guile-debug'.
283 Configure with --enable-guile-debug if you want a bunch of extra
284 functions used for debugging when developing Guile.
286 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
288 * procs.c (make-cclo): New undocumented debugging procedure: Make
289 compiled closure with internal procedure PROC and length LENGTH.
290 Only compiled if GUILE_DEBUG is defined.
292 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
294 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
296 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
298 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
299 with 3 or more args internally to the evaluator.
301 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
303 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
304 with 3 or more args internally to the evaluator. This is mainly
305 because we don't want to pass entry and exit points of the
306 debug support twice, but it also seems to increase the speed of
307 the evaluator for such calls (e. g. (+ 1 2 3)).
309 * * backtrace.c (scm_display_application): New procedure:
310 display-application; Set fancy printing parameters individually
311 for different types of display (backtrace, error, application).
312 (These should of course be customizable!)
314 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
315 clear the CHECK-flags.
317 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
319 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
321 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
323 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
324 from pairs with a GLOC in the car.
326 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
327 otherwise `symbol-hash' will behave badly.
328 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
329 we get segmentation fault!
331 * * symbols.c: Added #include "weaks.h". New functions:
332 `builtin-bindings' and `builtin-weak-bindings'. (These will be
333 moved to an extraneous library when we split libguile.)
335 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
337 * filesys.c (scm_stat): stat now takes fport arguments too as
338 documented in the manual.
340 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
342 * debug.c (scm_single_step): Bugfix: Call continuation with
343 scm_call_continuation instead of throwing to it.
345 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
347 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
348 argument wasn't declared to be optional.
350 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
352 * stime.c (scm_init_stime): Add feature "current-time".
354 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
356 * throw.h: prototype for scm_exit_status.
357 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
358 args to derive an exit status. Allows (quit) to work from a
360 (scm_exit_status): new function.
363 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
365 * eval.c (scm_deval): Removed some old code.
366 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
368 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
371 * symbols.c (msymbolize): Bugfix: Must initialize property list to
374 * procs.c: Introduce the existent C function scm_thunk_p at the
375 Scheme level as well.
377 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
379 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
380 used from C to easily lookup the value of a symbol in the current
383 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
385 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
386 scm_init_unif in this file. This will also fix a previous problem
389 * configure.in: Added AM_MAINTAINER_MODE
391 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
393 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
396 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
398 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
399 source files that are not always included in libguile but should
400 have their dependencies calculated by automake. This variable is
401 recognized by automake, no further magic is needed.
402 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
403 to deal exclusively with *.lo files, as it seems. The *.o files
404 are built automatically when the corresponding *.lo file gets
407 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
409 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
412 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
414 * unif.c (scm_array_set_x): minor change to argument error checking.
416 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
418 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
419 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
420 They should only be included in the library at configure.in's
422 (libguile_la_LDADD): Include the appropriate .lo files here.
423 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
424 so we know when to build them (and their .lo bretheren).
425 * configure.in (LIBLOBJS): New substituted variable. We let
426 configure decide which .o files to include in LIBOBJS, and then
427 put the corresponding list of .lo files in LIBLOBJS. The latter
428 is what we pass to libtool.
429 * Makefile.in, configure: regenerated.
431 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
433 * symbols.c (scm_sysintern0): New function. Contains the core of
434 old scm_sysintern but doesn't take a second value argument.
435 (scm_sysintern): Now uses scm_sysintern0.
436 (scm_sysintern_no_module_lookup): Renamed to
437 scm_sysintern0_no_module_lookup and doesn't take a second value
440 * symbols.h (scm_sysintern0: Added declaration.
442 * options.c (scm_init_opts): Use scm_sysintern0 instead of
443 scm_sysintern when interning option keys. Otherwise we risk
444 destroying the values of already interned variables.
446 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
447 scheme-level boolean (use SCM_NFALSEP).
449 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
451 (scm_backtrace): New function. (C version of old function from
452 boot-9.scm) Motivation: Make it possible to display backtraces
453 without depending on boot-9.scm. (I'm uncertain if this
454 motivation is good enough...)
456 * root.h (scm_root_state): Add member the_last_stack_var.
457 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
459 * root.c (mark_root): Mark scm_the_last_stack_var.
461 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
464 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
466 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
467 1. mark_lazy_catch didn't mark the smob.
468 2. Both functions above have standard variants:
469 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
470 free_lazy_catch --> scm_free0.
472 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
474 * throw.c (scm_internal_lazy_catch): New function.
475 (scm_lazy_catch): Rewritten to use it.
476 (scm_ithrow): Handle the new lazy catch representation.
477 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
478 that doesn't have a jmpbuf is a lazy catch clause.
479 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
480 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
481 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
483 (scm_init_throw): Register the new lazy-catch smob type.
484 * throw.h (scm_internal_lazy_catch): decl for new function.
486 * throw.c (scm_internal_catch): Doc fixes.
488 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
489 configure.in. Including this might cause problems if applications
490 that link against libguile include their own copies of alloca, but
491 if they're using autoconf, they should be adding libguile to LIBS
492 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
493 the copy in libguile, and things will be okay. (I think.)
495 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
497 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
499 strop.h: move prototypes too.
501 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
503 * posix.c (scm_init_posix): don't intern EINTR since it's now done
506 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
507 etc. I deleted them from filesys.c long ago, but didn't
508 notice they were here too (although ineffective since
509 sys/stat.h wasn't included).
511 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
513 * eval.c: Don't define alloca in GCC case. gcc will automatically
514 use __builtin_alloca if appropriate.
516 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
518 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
519 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
520 that values of automatic variables are preserved. See comments
521 for safe_setjmp for details.
523 Change from Thomas Morgan:
524 * variable.c: Include eq.h.
525 (var_equal): New function.
526 (variable_smob): Use var_equal as the discriminator for variables.
528 * throw.c (s_throw): Remove extraneous declaration.
530 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
531 * eval.c: Add necessary CPP cruft to support that.
532 * configure, Makefile.in, scmconfig.h.in: regenerated.
534 Change from Thomas Morgan:
535 * procprop.c (scm_procedure_properties): Convert the Scheme
536 boolean returned by scm_procedure_p into a C boolean before using
537 it as a condition for SCM_ASSERT.
538 (scm_procedure_property): Likewise.
540 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
541 indications of Unixness.
544 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
546 * * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
548 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
550 * read.c (scm_lreadr): use scm_misc_error to improve one of the
551 "unknown # object" error messages.
553 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
554 (scm_i_index) and declare it static. Add a 'direction' argument
555 to indicate what way the search should go.
556 (scm_i_index): throw out-of-range error instead of wrong-type-arg
558 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
559 strop.h: remove scm_i_index, scm_i_rindex prototypes.
561 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
563 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
565 * * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
566 to avoid clash with various scsh forks.
568 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
570 The following two changes (ramap.c, throw.c) are motivated by the
571 apparent unportability of forward declarations of static arrays of
572 the form `static foo bar[];'.
574 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
575 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
577 * throw.c (scm_throw): Moved above scm_ithrow.
579 * options.h: Removed the extern declarations of scm_yes_sym and
580 scm_no_sym since these are static.
582 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
584 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
586 * Makefile.am: remove AWK=@AWK@.
587 Add a rule for generating errnos.list.
588 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
590 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
591 don't extract errnos, just set a variable (avoids the
592 need to recompile error.c just because configure is run.)
594 * unif.h: update prototypes.
595 * unif.c (scm_uniform_array_read,write): change the offset and
596 length arguments to start and end, for consistency.
598 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
600 * ioext.h: update prototypes.
601 * * ioext.c (scm_read_delimited_x): replaces scm_read_line and
602 scm_read_line_x, it's a more general procedure using an
603 interface from scsh. read-line and read-line! are now defined
605 * Note that the new read-line trims the terminator
606 by default, previously it was appended to the returned string. An
607 optional argument specifies how to process the terminator (scsh
608 compatible). For the old behaviour: (read-line port 'concat).
609 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
610 returns a pair, but is converted to multiple values if the scsh
613 socket.h: update prototypes.
614 * socket.c (scm_recvfrom): for consistency with other procedures,
615 take start and end as separate optional arguments.
616 * (scm_recv, scm_recvfrom): don't allow the second argument
617 to be a size, only a buffer. Change the scheme names to
618 recv! and recvfrom!. Don't return the buffer.
620 * ioext.h, posix.h: move prototypes too.
621 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
622 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
623 "read.h" and "unif.h".
624 * ioext.c: include "chars.h"
626 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
628 * dynl.c: The dynamic linking and module registration functions
629 are now defined even when dynamic linking is not available for the
630 host system. Some of their functionality can be done without
631 dynamic linking; when it's really needed, they throw errors.
633 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
635 * configure.in: Only define DYNAMIC_LINKING when one of the system
636 dependent functions is detected.
637 * dynl.c (scm_dynamic_func): New function to get the address of a
638 function in a dynamic object.
639 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
640 produced by scm_dynamic_func as the thing to call.
642 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
644 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
645 (scm_register_module_xxx, scm_registered_modules,
646 scm_clear_registered_modules): New functions.
648 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
650 * symbols.c (scm_sysintern): Renamed to
651 scm_sysintern_no_module_lookup.
652 (scm_sysintern): New function to take the place of the old
653 scm_sysintern. It uses the current toplevel lookup closure to give
654 the symbol its value. This is a temporary hack to put packages
655 like gtcltk into their own module.
656 (scm_can_use_top_level_lookup_closure_var): New variable to tell
657 us whether `scm_top_level_lookup_closure_var' has been initialized
659 * eval.c (scm_init_eval): Set it.
661 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
663 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
664 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
666 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
668 * (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
669 scm_sys_dup): deleted: FD capability will be added to other
671 * Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
672 scm_fd_free, fd_smob, scm_intern_fd.
673 * (scm_open): renamed from scm_sys_open. Return a port instead of
674 an FD object. Make the mode argument optional.
675 * (scm_sys_create): deleted, it's just a special case of open.
676 (scm_init_filesys): move interning of constants O_CREAT etc.,
677 here (were previously using SCM_CONST_LONG macro).
678 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
680 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
681 include "fports.h" and <stdio.h>
682 (scm_stat, scm_select): don't support FD objects.
684 * error.h: adjust scm_syserror_msg prototype.
685 * error.c (scm_syserror_msg): take an extra argument for errno.
686 Using the global value didn't always work, since it could be
687 reset by procedure calls in the message or args arguments.
689 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
690 I don't understand why the check was there (and what about the
693 * strop.c (scm_string_copy): allow shared substrings to be copied.
695 * unif.h: corresponding change to prototypes.
696 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
697 recognize two new optional arguments: offset and length. Allow
698 the port argument to be an integer (file descriptor, for scsh).
699 Include <unistd.h> for "read" prototype.
701 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
703 * socket.c: don't include filesys.h.
705 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
707 * Makefile.am: add AWK=@AWK@ (?)
709 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
711 Add a rule to generate errnos.c from errnos.
712 * error.c (scm_init_error): include errnos.c.
713 * errnos_cnvt.awk: new file, converts the list of errno codes to
715 * errnos_get.c: new file.
716 * errnos.default: new file, contains errnos to try if they can't
717 be extracted from errno.h.
718 * configure.in: if using GCC, try and extract errno codes from
722 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
724 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
725 * Makefile.am: Made libguile into a libtool library.
726 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
727 Set libtool_libs to indicate that libguile is a libtool library.
728 See guile/ChangeLog for details.
729 * .cvsignore: ignore "*.lo", the libtool library objects.
731 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
733 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
734 use htons in getservbyport argument.
736 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
738 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
739 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
742 * objprop.c (scm_object_property): No need to take the CDR of the
743 value returned by scm_object_properties, since Aug 20 change.
745 * configure.in: When checking for struct linger, #include
746 <sys/types.h> as well as <sys/socket.h>. I've never known
747 <sys/types.h> to cause any portability problems, and Solaris's
748 <sys/socket.h> needs it.
749 * configure: Rebuilt.
751 I think the Sun compiler has chosen a perverse way to interpret
752 ANSI declarations combined with K&R definitions. We'll
753 appease it a little bit. But when it invades France, we fight.
754 * print.c (scm_iprlist): Change 'tlr' argument to an int.
755 * print.h (scm_iprlist): Here too.
756 * numbers.c (scm_divbigdig): Change definition to match
757 declaration in numbers.h.
758 * unif.c (scm_makflo): Change definition to match declaration in
761 * init.c (scm_boot_guile): Don't return the value of
762 scm_boot_guile_1. This function doesn't return a value;
763 scm_boot_guile_1 doesn't return a value (or return at all).
765 * eval.c (unmemocopy): Add a semicolon to appease the Sun
768 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
769 compile. I have a feeling this function is a bad idea anyway ---
770 one should always test for features, not systems.
772 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
773 semicolons. Only pure luck kept this from being noticed earlier.
775 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
777 * socket.c (scm_recvfrom): Added missing semicolon.
779 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
781 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
782 the buffer and start and end positions for scsh networking
785 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
787 * configure.in: Revert previous change to this file; the problem
788 is due to transient automake weirdness.
789 * configure: Rebuilt.
791 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
792 PLUGIN/guile.libs. configure generates the latter from the former.
793 * Makefile.in: Rebuilt.
795 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
796 need this if we install scripts, like guile-snarf.
797 * configure: Rebuilt.
799 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
801 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
803 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
805 * socket.c (scm_addr_vector): fix faulty scm_listify.
807 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
809 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
810 style block comment is no longer considered an error.
812 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
814 * PLUGIN/guile.libs.in: New file.
815 * PLUGIN/guile.libs: Removed from repository.
816 * configure.in: Create PLUGIN/guile.libs from
817 PLUGIN/guile.libs.in. This is for including additonal libraries
818 needed for dynamic linking.
819 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
820 instead of PLUGIN/guile.libs.
822 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
824 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
826 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
827 occurrences of the given element from the list, not just the
828 first. This is how the Emacs Lisp functions behave, how the
829 analogous Common Lisp functions behave, and (I believe) how the
830 older Maclisp functions worked. I realize that this change may
831 break code, but it seemed better to break it before the Guile
834 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
835 Their prototypes were already present in gc.h, but they weren't
837 (scm_init_storage): Initialize scm_protects.
838 * root.c (scm_protects): New element of scm_sys_protects.
840 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
842 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
844 * libguile.h: Added #include "libguile/net_db.h".
846 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
847 30 change. That file is only meant for communication between the
848 configuration process and load.c. If code linked against libguile
849 wants to get at the paths mentioned in libpath.h, it can call
850 functions declared in load.h.
852 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
854 * libguile.h: Removed #include "libguile/fdsocket.h"
856 * net_db.c: Added #include <sys/socket.h>.
858 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
860 * filesys.c (scm_input_waiting_p): use select in preference to
861 FIONREAD, since the latter doesn't detect EOF.
862 Throw error if neither select nor FIONREAD available.
864 * socket.c (scm_connect): take a port, not a fd object.
865 (scm_fill_sockaddr): throw an error if fam is not recognised.
866 (scm_bind): use scm_fill_sockaddr.
867 (scm_listen): take a port, not a fd object.
868 (scm_accept): take and return a port. return #f in the car if
870 (scm_sock_fd_to_port): new procedure.
871 (scm_socket): use scm_sock_fd_to_port.
872 (scm_addr_vector): throw error if unrecognised address type.
873 take an extra argument with the calling procedure name.
874 (scm_getsockname): take a port. return #f if address can't be got.
875 (scm_getpeername): take a port. return #f if address can't be got.
876 (scm_recvfrom): take a port. return #f for address component if can't
878 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
879 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
881 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
883 * throw.c (scm_internal_catch): Make body funcs and handler funcs
884 use separate data pointers, to allow them to be designed
885 independently and reused.
886 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
887 Renamed from catch_body, catch_handler, and uncaught_throw; made
889 (struct scm_catch_body_data): Renamed from catch_body_data; moved
891 (scm_catch): Use the above.
892 (scm_throw): Don't bother printing a message for an uncaught
893 throw; we establish a default handler in init.
894 * throw.h (scm_internal_catch): Prototype updated.
895 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
897 (struct scm_body_thunk_data): New structure, used as data
898 argument to scm_body_thunk.
899 * init.c (struct main_func_closure): New structure, packaging up
900 the data to pass to the user's main function.
901 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
902 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
903 scm_internal_catch to establish a catch-all handler, using
904 scm_handle_by_message. This replaces the special-case code in
906 (invoke_main_func): Body function for scm_internal_catch; invoke
907 the user's main function, using the main_func_closure pointer to
908 decide what to pass it.
909 * root.c (struct cwdr_body_data): Remove handler_proc member.
910 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
911 (cwdr_handler): Removed.
913 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
915 * socket.h (SCM_P): update bind prototype.
916 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
918 (scm_socket): return a port, not a file descriptor object.
919 include "fports.h" and <unistd.h>
920 (scm_bind): take a port, not a file descriptor object.
921 take an extra argument for address args.
923 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
924 INADDR_NONE, INADDR_LOOPBACK.
926 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
928 * init.c: include net_db.h and not fdsocket.h.
929 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
931 * Makefile.am: corresponding changes.
932 * socket.h: renamed from fdsocket.h, fix names.
933 * net_db.h: renamed from socket.h, fix names.
934 * socket.c: renamed from fdsocket.c.
935 remove _sys from procedure names.
936 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
937 add "socket" to features list.
938 * net_db.c: renamed from socket.c.
939 remove _sys from procedure names.
940 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
941 add "net-db" to features list.
942 include "net_db.h". don't include <sys/socket.h> or
945 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
947 * tags.h (scm_tags): Removed comma at end of last enumerator.
949 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
951 Don't use GCC extensions to allocate space for debugging frames.
952 (Here he goes again! Why do we put up with this?!)
953 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
954 an scm_debug_info structure, not an in-line array of them. Add
955 'info' member, to say how many vect elements we've used, for eval
957 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
958 a new variable debug_info_end to mark the end of vect, instead of
959 the address of the 'info' pointer itself.
960 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
961 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
962 (SCM_APPLY): Explicitly allocate space for debug.vect.
963 * debug.c (scm_m_start_stack): Same, for vframe.vect.
964 * stacks.c: Adjusted for new debug frame structure.
965 (RELOC_INFO, RELOC_FRAME): New macros.
966 (stack_depth, read_frames): Use them, and new scm_debug_frame
967 element 'info', instead of magically knowing that eval frames have
968 an info pointer sitting after vect.
969 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
971 (scm_init_stacks): Formatting tweaks.
973 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
975 Give GCC more control flow information, so it can be sure that
976 variables aren't used uninitialized.
977 * error.h (scm_error, scm_syserror, scm_syserror_msg,
978 scm_sysmissing, scm_num_overflow, scm_out_of_range,
979 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
980 scm_misc_error): Tell GCC that these functions never return.
981 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
982 out the field type, call abort if SCM_ASSERT returns, to placate
984 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
985 scm_wta ever returns. We can't handle this case anyway, and this
986 gives the optimizer more information.
987 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
988 scm_wta ever returns.
990 In some cases, the code is fine, but GCC isn't smart enough to
991 figure that out; this usually happens when one variable is only
992 initialized and used when a particular condition holds true, and
993 we know that condition will never change within a given invocation
994 of the function. In this case, we simply initialize the variables
995 to placate the compiler, hopefully to a value which will cause a
996 crash if it is ever actually used.
997 * print.c (scm_iprin1): Initialize mw_pos.
998 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
999 * throw.c (scm_ithrow): Initialize dynpair.
1000 * unif.c (scm_uniform_vector_ref): Initialize cra.
1001 * struct.c (init_struct): Initialize prot.
1002 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
1004 * strports.c (scm_eval_0str): Don't return uninitialized garbage
1005 if EXPR contains no expressions.
1007 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
1009 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
1010 cause an infinite loop (???). So much for the algebraic
1011 equivalency of variable-sized arrays and alloca...
1013 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
1015 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
1016 a SCM boolean, not a C boolean.
1018 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
1020 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
1021 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
1022 rules for raising scm_mtrigger. Previously, unfortunate but not
1023 unlikely circumstances could result in almost constant invokation
1024 of the gc. Now, this situations should be less likely, but they
1025 are not prevented completely.
1027 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
1029 * numbers.c (scm_fuck): Procedure removed; looks like old test
1031 * numbers.h: Prototype removed.
1033 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
1035 * debug.h (scm_debug_frame): Change `vect' member from an in-line
1036 array to a pointer, to match my Nov 21 change in eval.c.
1038 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1040 * libguile.h: Added #include "libguile/backtrace.h", #include
1041 "libguile/stacks.h".
1043 * strings.c (scm_string scm_make_string scm_string_ref
1044 scm_string_set_x scm_string_equal_p scm_string_append):
1045 Bugfix according to scm patch from Aubrey Jaffer:
1046 Corrected long-standing
1047 (not (eqv? (integer->char 128)
1048 (string-ref (make-string 1 (integer->char 128)) 0)))
1049 bug found by John Kozak <jk@noontide.demon.co.uk>.
1051 * strports.c, strports.h: Make scm_eval_0str return the value of
1052 the last expression evaluated (previously, it returned void).
1054 * strports.c, strports.h: New function: scm_read_0str. Does what
1057 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1059 * simpos.c (scm_getenv): return #f if string can't be found in the
1060 environment instead of throwing an exception, for compatibility
1061 with numerous other systems.
1063 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
1065 * Makefile.am (.c.x): Use guile-snarf.
1066 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
1068 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
1070 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1072 * backtrace.c (scm_display_error_message): Made non-static, and
1073 renamed from display_error_message.
1074 * backtrace.h (scm_display_error_message): Added extern decl.
1075 * throw.c (uncaught_throw): Use it to display the error message.
1077 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
1079 * inet_aton.c: Use #if 0, not #ifdef 0.
1081 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
1083 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
1084 to convert the returned value.
1085 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
1086 the offset argument.
1088 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1090 Add new interface to catch/throw, usable from C as well as
1092 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
1093 (scm_internal_catch): New function, replaces...
1094 (scm_catch_apply): Deleted.
1095 * throw.c (scm_catch_apply): Deleted; replaced with a more general
1096 mechanism which is a bit more code, but can be used nicely from C
1097 and implement the Scheme semantics as well.
1098 (scm_internal_catch): This is the replacement; it's named after
1099 the analogous function in Emacs.
1100 (scm_catch): Reimplemented in terms of the above.
1101 (struct catch_body_data, catch_body, catch_handler): New
1102 functions, used by scm_catch.
1103 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
1104 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
1105 support for new cwdr.
1107 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
1110 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
1112 * acconfig.h: Added DYNAMIC_LINKING symbol.
1113 * configure.in: Add option and checks for dynamic linking.
1114 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
1115 dynl.h: New files for dynamic linking support.
1116 * Makefile.am (libguile_a_SOURCES):
1118 (modinclude_HEADERS): Added "dynl.h".
1119 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
1121 * init.c (scm_boot_guile_1): Call
1122 scm_init_dynamic_linking to initialize dynamic linking support.
1124 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
1126 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
1127 (as we Schemers say). It needs to be global, so that I can tweak
1128 it for the proper operation of unexec.
1129 (scm_boot_guile_1_live): New variable, see above.
1131 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
1133 * guile-snarf.sh: Removed.
1134 * PLUGIN/guile.libs: Added dependency for -lm.
1135 * acinclude.m4: Renamed from aclocal.m4.
1136 * PLUGIN/greet: Removed.
1137 * Makefile.am, aclocal.m4: New files.
1138 * configure.in: Updated for Automake.
1140 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
1142 * eval.c (scm_definedp): Use top_level_lookup_closure_var
1143 and not top_level_lookup_thunk_var.
1145 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
1147 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
1149 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
1151 * eval.c (scm_definedp): Incompatibly changed to be a builtin
1152 Scheme function, instead of syntax. Single argument is now a
1155 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1157 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
1158 scm_ra_divide): Properly terminate statements passed as arguments
1159 to IVDEP macros. (Thanks to Bernard Urban.)
1161 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
1162 with non-constant sizes. (Thanks to Bernard Urban.)
1164 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1166 It's an "eval closure", not an "eval thunk." A thunk is a
1167 function of no arguments.
1168 * root.h (struct scm_root_state): Renamed
1169 top_level_lookup_closure_var from top_level_lookup_thunk_var.
1170 (scm_top_level_lookup_closure_var): Renamed from
1171 scm_top_level_lookup_thunk_var.
1172 * root.c (mark_root): Uses changed.
1173 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
1174 * init.c (scm_start_stack): Uses changed.
1175 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
1176 Change scheme-visible name to *top-level-lookup-closure* from
1177 *top-level-lookup-thunk*.
1179 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
1181 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
1182 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
1184 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
1186 * gc.c (struct scm_heap_seg_data): Doc fixes.
1188 * gc.c (scm_gc_sweep): Empty all segments' freelists before
1189 sweeping. Then, prepend each segment's free cells to its
1190 freelist, rather than wiping out the old value. (Thanks to Marius
1193 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
1194 scm_check_freelist, scm_debug_newcell): New functions and
1195 variables, for debugging freelist problems.
1196 * pairs.h (SCM_NEWCELL): New debugging version added.
1197 * gc.h (scm_debug_newcell): Added extern declaration, used by
1198 debugging version of SCM_NEWCELL.
1200 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1202 On some systems <libc.h> conflicts with <unistd.h>, and should not
1203 be #included at all.
1204 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
1205 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
1206 * configure.in: Call it.
1207 * posix.c, filesys.c: Use its results to decide whether or not to
1209 * configure, scmconfig.h.in: Rebuilt with autoconf and
1212 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1214 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
1215 pointer to the stdio stream before calling scm_setbuf0, so the
1216 latter will be able to retrieve it. I'm surprised this didn't
1217 segfault earlier. (Thanks to Christopher Lee.)
1219 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1221 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
1224 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1226 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
1227 number of stack narrowing specifier pairs. The first specifier in
1228 a pair controls inner border, the second the outer border. A
1229 number means cut that number of frames, a procedure object means
1230 cut until that object is found in operator position in a frame.
1232 * root.c (cwdr): Bugfix.
1234 * read.c: Recording of positions disabled by default.
1236 * procs.c (scm_closure_p): New function.
1238 * posix.c (scm_tmpnam): New function.
1240 * load.c: Added #include "throw.h".
1241 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
1244 * load.c, load.h (scm_read_and_eval_x): New function.
1246 * eval.c: Renamed debug option "deval" to "debug".
1248 (scm_eval_x): `eval!' is no longer accessible from the scheme
1249 level. Motivation: We can't allow operations which introduce
1250 glocs into the scheme level. Guile's type system can't handle
1251 these as data. Use `eval' or `read-and-eval!' as replacement.
1253 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
1254 SCM_CONSP since this is a macro!; Set vframe.prev to
1255 scm_last_debug_frame instead of 0. In this way we can look
1256 "above" the virtual start stack frame if we wish.
1257 (scm_debug_hang): New function: Useful for debugging Guile in
1258 certain tricky situations. Will probably be removed later...
1260 * debug.h: Changed semantics of debug option "backtrace". This
1261 option now only indicates whether we want automatic backtrace at
1264 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1266 * ports.c: #include "filesys.h"
1267 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
1269 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
1270 Motivation: This is system specific code which is related to file
1271 I/O. It also may use select. Added code by Gary Houston to
1272 detect presence of character in stdio buffers.
1274 * libguile.h: #include "libguile/libpath.h"
1276 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
1277 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
1278 SCM_SITE_DIR; Install libpath.h among the other include files.
1280 * load.c, load.h (scm_sys_package_data_dir): New function.
1282 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1284 * stacks.h: Bugfix: Don't use tail-array length field as stack
1285 length field! This screwed GC.
1287 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1289 * _scm.h: Added #ifndef around definition of macros min and max.
1291 * __scm.h: Added hooks for threads to plugin to in ints protection
1292 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
1293 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
1294 the main code in these macros duplicated and spread over multiple
1295 files. Renamed SCM_THREADS_SWITCHING_CODE ->
1296 SCM_THREAD_SWITCHING_CODE.
1298 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
1300 * snarf.h: New file.
1301 * guile-snarf.sh: New file.
1302 * Makefile.in (inner_h_files): Added snarf.h
1303 (ancillary, install, uninstall, distclean): Added actions for
1305 (.c.x): Use guile-snarf.
1306 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
1307 (gen_c_files): Note that these depend on guile-snarf.
1308 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
1309 now in "snarf.h". Added #include "snarf.h" to get them.
1310 * libguile.h: Added #include "snarf.h".
1311 (Patches applied and tweaked by Jim Blandy.)
1313 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1315 * socket.c: Use K&R style declaration for 'close'; the GNU coding
1316 standards suggest against providing prototypes for system
1317 functions. Thanks to Greg Troxel.
1319 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1321 * strports.c (scm_eval_0str): New function.
1322 #include "read.h", to get prototype for scm_read.
1323 * Makefile.in (strports.o): Update dependencies.
1324 * strports.h: New prototype.
1326 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
1327 scheme name from "int?" to "integer?". It seems to do the job.
1328 * numbers.h: Rename prototype too.
1329 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
1332 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
1333 scm_num_eq_p): Rename these according to R4RS conventions: call
1334 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
1335 to making libguile R4RS compliant without ice-9...
1337 * load.c (scm_sys_search_load_path): Search for files under all
1338 extensions listed in the %load-extensions variable. If FILENAME
1339 is absolute, return it unchanged, without searching the load path.
1340 (scm_loc_load_extensions): New variable, pointing to
1341 %load-extensions' value cell.
1342 (scm_init_load): Initialize it, and the value it points to.
1343 (scm_primitive_load_path): Improve error reporting.
1345 * load.c (scm_loc_load_hook): New variable, pointing to value cell
1346 of new Scheme variable %load-hook.
1347 (scm_primitive_load): Apply %load-hook to filename.
1349 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
1351 * configure.in: add tests for figuring out whether buffered data
1352 is available in a FILE structure, which is needed by char-ready.
1354 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
1357 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
1358 exceptions using misc_error instead of syserror. It seems a bit
1359 odd to throw an exception if a string can't be found in the
1360 environment, but it's consistent with open-file, stat etc.
1361 (simpos.h): remove sys_ from getenv.
1363 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
1364 occurs, throw an error instead of returning errno. Return value
1366 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1368 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1370 * filesys.c (scm_stat2scm): derive file type and permissions from
1371 the stat mode and append them to the returned vector.
1372 There isn't much overhead in doing this and it avoids the need to
1373 work with S_IRUSR et al. in Scheme.
1374 Define symbols scm_sym_regular etc.
1375 (scm_init_filesys): don't intern S_IRUSR etc.
1377 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1378 and s_primitive_load_path.
1380 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1382 * error.h: don't declare error symbols. prototype for scm_misc_error.
1384 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1387 * error.c: use SCM_SYMBOL to set up error keys.
1388 scm_misc_error: new procedure.
1390 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1392 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1393 between `#!' and `!#' is ignored.
1394 (skip_scsh_block_comment): New function.
1396 * feature.c (scm_set_program_arguments): New argument, FIRST.
1397 * feature.h: Update prototype.
1398 * init.c (scm_boot_guile_1): Pass new argument to
1399 scm_set_program_arguments.
1401 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1403 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1404 (scm_boot_guile): Call scm_set_program_arguments here, later than
1405 the old initialization.
1407 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1408 initialization procedure.
1409 - Delete in, out, err arguments; there are other perfectly good
1410 ways to override these when desired.
1411 - Delete result argument; this function shouldn't ever return.
1412 - Rename init_func argument to main_func, for less confusion.
1413 - Delete boot_cmd argument; main_func is more general.
1414 -Add 'closure' argument, to help people pass data to main_func
1415 without resorting to global variables.
1416 - Abort if reentered; don't bother returning an error code.
1417 - Call scm_init_standard_ports to set up the default/current
1418 standard ports; no need to pass them to scm_start_stack.
1419 - Remove code to evaluate the boot_cmd, and start the repl; let
1420 the user do something like that in main_func if they want.
1421 - Remove code to package up a return value; main_func can do any
1423 - Call exit (0), instead of returning.
1424 (scm_start_stack): Don't initialize the I/O ports here; that's
1425 weird. Delete in, out, err arguments. Move guts to
1426 scm_init_standard_ports, scm_stdio_to_port.
1427 (scm_init_standard_ports): New function, to set up current and
1428 default standard ports.
1429 (scm_start_stack, scm_restart_stack): Make these static.
1430 * init.h (scm_boot_guile): Adjust declaration.
1431 (scm_start_stack, scm_restart_stack): Remove externally
1432 visible declarations for these.
1433 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1435 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1436 written out several times in scm_start_stack.
1437 * fports.h: New declaration for the above.
1439 * feature.c (scm_set_program_arguments): New function.
1440 * feature.h: New declaration for the above.
1442 * ports.c: Formatting tweak.
1444 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1446 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1447 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1448 for obtaining the address of a car or cdr field. Motivation:
1449 &SCM_CXR make assumptions about the internal structure of the
1452 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1453 Motivation: see SCM_CXRLOC.
1455 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1456 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1457 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1458 Motivation: Safer use. Some other macros are defined in terms of
1459 these operations. If these are defined using the SCM_SETCXR
1460 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1461 to inefficiency and an <e1> with side-effects could potentially
1462 break. Also, these particular operations are heavily utilized in
1463 the garbage collector. In unoptimized code there will be a
1466 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1467 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
1468 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
1469 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
1470 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
1471 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1472 vports.c: Cleaned up use of pairs: Don't make any special
1473 assumptions about the internal structure of selectors and
1474 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1475 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1476 (Among other things, this change makes it easier to build Guile
1477 with certain compilers which have problems with casted lvalues.)
1479 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1481 * stacks.c: Improve selection of relevant stack frames when making
1482 a stack object. Introduce one level of indirection in the stack
1483 object to make it possible to "narrow" to a certain region of the
1484 stack. This facilitates making use of more clever algorithms (not
1485 implemented) for selecting relevant frames and gives a cleaner
1486 design since selection of frames can be done independently of
1487 extraction of frames from the real stack.
1488 (scm_stack_id): Also take #t as argument which means look at
1491 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1492 Turn n_tail into an integer directly representing current number
1493 of frames in stack. Add field tail.
1495 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1497 * debug.c (scm_make_memoized): Made it available at scheme level.
1498 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1499 SCM_NIMP before applying heavier predicates in argument checking.
1500 (scm_local_eval): Also take memoized object as argument.
1502 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1503 aren't created with zero length, but should such a strange
1504 creature suddenly turn up...
1506 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1508 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1509 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1511 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1513 * variable.c (scm_make_variable): Make the name hint optional, as
1515 (anonymous_variable_sym): Renamed from variable_sym. All uses
1518 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1519 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1520 of scm_primitive_load_path was also changed to
1521 "primitive-load-path", from "%try-load-path". Callers changed.
1522 We'd like to respect the convention that a function named
1523 "try-mumble" should behave just like the function called "mumble",
1524 but return #f instead of signalling some error.
1525 * load.h: Rename prototypes.
1527 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1529 * print.c (make_print_state, grow_print_state), print.h: Modified
1530 the print state representation: Don't use a tail array for
1531 recording of circular references. Resizing of the print state
1532 structure invalidates the print state pointer. To avoid passing
1533 around an indirect print state reference to all printing
1534 functions, we instead let the print state reference a resizable
1537 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1539 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1540 Don't crash when passed an improper list terminated by a
1541 non-immediate value.
1543 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1545 Allocate data for structures on an eight-byte boundary, as
1546 required by the tagging system.
1547 * struct.c (alloc_struct): New function.
1548 (scm_make_struct, scm_make_vtable_vtable): Call it.
1549 * struct.h (scm_struct_n_extra_words): Bump to 3.
1550 (scm_struct_i_ptr): New "field".
1551 * gc.c (scm_gc_sweep): When we need to free the data, use the
1552 information stored by alloc_struct to find the beginning of the
1553 block allocated to the structure, so we can free it.
1555 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1557 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1560 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1561 (scm_debug_info): New member: id.
1563 * stacks.c: Stacks are now represented as structs; Stacks have an
1564 id given to them by `start-stack'.
1565 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1567 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1568 Changed stack representation.
1570 * debug.c (scm_procedure_name): Try procedure property `name' for
1571 compiled closures aswell.
1573 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
1575 * eval.c: scm_i_name moved to gsubr.c
1576 (scm_m_define): Record names of all kinds of procedure
1577 objects. (Earlier, only closures were recorded.)
1579 * procprop.h: Added declaration of scm_i_name.
1581 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1582 (scm_make_gsubr): Record names of compiled closures.
1584 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1586 * debug.c, debug.h: Removed obsolete code.
1588 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1589 stacks.c: Renamed regs --> scm_contregs.
1591 * print.c (scm_free_print_state): Cleanup print state before
1592 returning it to pool. It is better to do it here than in
1593 scm_prin1 since scm_prin1 is called often.
1595 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1596 s_set_source_property_x): Check that first argument is a pair or a
1599 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1600 scm_i_line, scm_i_column and scm_i_breakpoint global.
1602 * init.c: Added #include "backtrace.h" and #include "stacks.h".
1603 (scm_boot_guile_1): Added calls to scm_init_backtrace and
1606 * debug.h: Added debug object smob declaration and macro
1609 * configure.in: Build with backtrace.o and stacks.o if debug
1612 * Makefile.in: Added entries for new files: backtrace.c,
1613 backtrace.h, stacks.c and stacks.h.
1615 * symbols.c (scm_sym2ovcell): Fixed documentation.
1617 * _scm.h (min, max): Added.
1619 * async.c: Moved `min' macro to _scm.h.
1621 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1622 SCM_BACKTRACE_INDENT.
1624 * eval.c: Added new debug options `maxdepth' and `indent'.
1626 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
1628 * print.h: Added selector SCM_PRINT_STATE.
1630 * print.c: New functions: scm_make_print_state,
1631 scm_free_print_state.
1633 * print.h: Added declarations for scm_make_print_state,
1634 scm_free_print_state.
1636 * debug.c (scm_m_start_stack): New acro.
1638 * debug.h: Small cleanup.
1640 * init.c (scm_boot_guile_1): Moved scm_init_debug below
1643 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

1663 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
1664 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
1665 declare functions with prototypes. (Patch thanks to Marius
1668 More prototype-related changes from Marius Vollmer:
1669 * gdb_interface.h: Wrapped header file in #ifdef/#endif
1670 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
1671 * ports.h (ptobfuns): Added prototypes. This means some casting in
1673 * fports.c: Added casts for initializations, since the functions
1674 are defined to take FILE * as their stream argument, not SCM.
1675 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
1676 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
1677 to `char *str_data' to conform to prototype.
1679 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1681 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
1683 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
1685 * stime.c, stime.h: use SCM_P method.
1687 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1689 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
1690 be given at least two arguments. Insist that lst's last element
1691 be a list, but don't make any requirements of its predecessors.
1693 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1695 * eval.c (scm_nconc2last): Revert last change; there seems to be
1696 other stuff going on here.
1698 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1700 * eval.c (scm_nconc2last): Make sure that each element of lst
1701 (which is a list of argument lists, except for the tail) is a
1702 proper list, i.e., finite and terminated by '().
1704 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1706 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
1709 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
1710 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
1713 * vectors.c (scm_make_vector): Fill vectors with the undefined
1714 value, to help make Guile Scheme code more portable to other
1717 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
1718 * symbols.h, tags.h: Doc fixes.
1720 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
1722 * async.c (scm_take_signal): Doc fixes.
1724 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
1726 * numbers.c (scm_divbigint): When the remainder is zero, we don't
1727 want to subtract it from the modulus; we just want to leave it
1730 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
1732 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
1735 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
1737 * throw.c (scm_catch_apply): Finished implementation of
1740 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
1742 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
1744 (scm_init_filesys): set "i/o-extensions" feature.
1747 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
1749 * Makefile.in (root.o): Correct dependencies.
1751 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
1753 * Makefile.in: Added dependency entry for root.o.
1755 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
1756 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
1758 * init.c (scm_start_stack): Set initial root continuation number
1761 * procs.c: New function: scm_thunk_p.
1763 * procs.h: Added declarations of scm_thunk_p.
1765 * root.c: Renamed `call-with-new-root' -->
1766 `call-with-dynamic-root'.
1767 (cwdr): Removed allocation of new root state. This should be done
1768 separately by use of scm_make_root.
1769 (scm_apply_with_dynamic_root): New function: Does what it
1770 sounds like. Needed when spawning threads.
1772 * root.h: Added member last_debug_frame to root state.
1773 Added #include "libguile/debug.h"
1775 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
1776 arguments. The motivation is that code in root.c needs catch
1777 functionality, and we want to avoid code duplication.
1778 New functions: scm_catch, scm_lazy_catch. These are wrappers for
1779 scm_catch_apply. scm_lazy_catch is intended to introduce catch
1780 handlers that run without popping the stack into the dynwind
1783 * throw.h: Added prototypes for scm_catch_apply and
1786 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1788 * root.h (scm_root, scm_set_root): Decouple thread support details
1789 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
1790 SCM_SET_THREAD_LOCAL_DATA.
1792 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
1793 and tortoise scanning loop.
1795 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
1797 * Makefile.in: Rebuild dependencies.
1799 * libguile.h: #include "libguile/print.h" before "smob.h", since
1800 the latter uses the print_state structure.
1802 * throw.c (scm_ithrow): Use the correct variable when checking to
1803 see if a given element of scm_dynwinds is a valid catch.
1805 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
1806 structure, abort; don't just silently ignore the garbage.
1808 * _scm.h: #include "print.h" here, since it seems to be used just
1810 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
1811 strports.c, unif.h: Don't #include "print.h".
1813 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1815 * feature.h (scm_loc_features): Removed external declaration.
1816 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
1818 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1820 * feature.c (scm_init_feature): Added threads feature (needs to be
1821 initialized here, since features doesn't exist when
1822 scm_init_threads is called).
1824 * libguile.h: Added #include "libguile/../threads/threads.h".
1825 (This is a kludge to get thread support working. This should be
1828 * configure.in, acconfig.h: Added flags for thread support.
1830 * scmsigs.c: Define `signal' to be `pthread_signal' if using
1833 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
1834 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
1837 * _scm.h: Added conditional #include "threads.h"
1839 * __scm.h (SCM_ASYNC_TICK): Added call to macro
1840 SCM_THREADS_SWITCHING_CODE.
1842 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
1843 allocate the basic dynamic root object.
1844 (scm_boot_guile): Added call to scm_init_root.
1846 * root.c, root.h: Added root smob.
1847 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
1848 functions: Implements dynamic roots mostly according to spec in
1849 SCM manual. Main difference is that the second argument is a
1850 throw handler rather than an error "thunk".
1852 * root.h: Added declaration of scm_init_root.
1854 * root.c: Added #include "genio.h", #include "smob.h", #include
1855 "pairs.h", #include "throw.h", #include "dynwind.h", #include
1857 (scm_init_root): Added #include "root.x".
1859 * throw.c: Added #include "stackchk.h"
1860 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
1861 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
1862 can be used in scm_call_with_new_root; Added reenabling of stack
1863 checking when catching a throw.
1865 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
1867 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
1869 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
1870 element is not found, as per R4RS.
1872 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1874 * list.c: Doc fixes throughout.
1876 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1878 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
1879 declare the char * to be const. Avoids a warning in rgx.c.
1881 * ports.h: spelling fix.
1883 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
1886 * load.c (scm_sys_try_load_path): throw an error if file not found
1887 (like it says it in NEWS).
1889 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1891 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
1892 PROPS slot to '(), not #f; it's an empty alist.
1894 * throw.h, throw.c: Use SCM_P instead of #if hair.
1896 Remove special support for uncaught throws; see throw.c for
1898 * throw.c (uncaught_throw): New function.
1899 (scm_ithrow): Call uncaught_throw if we don't find a throw
1900 target; don't mess with scm_bad_throw_vcell.
1901 (scm_bad_throw_vcell): Variable deleted.
1902 (scm_init_throw): Don't initialize it.
1904 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
1907 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1909 * numbers.c (scm_istr2int): If the number is short (as most
1910 numbers are), just call scm_small_istr2int to deal with it.
1911 (scm_small_istr2int): New function, created by un-#ifdefing the
1912 non-bignum version of scm_istr2int and renaming it.
1914 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
1916 * load.c (scm_sys_try_load): don't check whether value returned
1917 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
1918 Change the Scheme name from %try-load to primitive-load.
1920 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
1921 Can avoid passing a message, allowing it to be derived in the
1922 error handler (e.g., if we want to throw to the key both from
1925 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
1927 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
1928 references now have a new appearance which is more compact and
1929 also gives a clue about what the target of the reference is.
1930 By setting parameters in the print state, more fancy printing can
1931 be achieved. This is used by the (not yet commited) backtrace
1934 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
1936 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
1939 * print.c: Added #include "struct.h". Removed function
1942 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
1943 scm_iprin1. Removed prototype for scm_prlist.
1945 * arbiters.c (prinarb),
1946 async.c (print_async),
1947 debug.c (prindebugobj, prinmemoized),
1948 eval.c (prinprom, prinmacro),
1949 filesys.c (scm_fd_print, scm_dir_print),
1951 mallocs.c (prinmalloc),
1952 numbers.c, numbers.h (scm_floprint, scm_bigprint),
1953 smob.h (scm_smobfuns),
1954 srcprop.c (prinsrcprops),
1956 unif.c, unif.h (scm_raprin1, rapr1),
1957 variable.c (prin_var): Changed argument `int writing' to
1958 `scm_print_state *pstate'.
1960 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
1961 that it will be called before scm_init_print.
1963 * print.c (scm_prin1): Print states are now allocated when calling
1964 scm_prin1 and then passed around to all printing functions as an
1965 argument. A cache `print_state_pool' enables reuse of print
1967 (scm_make_print_state): New function.
1968 (scm_iprin1): Adaption to print states.
1969 (scm_iprlist): An initial "hare and tortoise" scan brings down
1970 time complexity to O (depth * N). (Better time complexity will be
1971 achieved when the printing code is completely rewritten.)
1973 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1975 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
1976 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
1977 it gets done whether or not the cache variable has a value.
1979 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
1981 Distinguish #f and ().
1982 * __scm.h: #undef SICP.
1983 * pairs.h (SCM_EOL): Delete this definition, equating it with
1985 * tags.h (SCM_EOL): Give it a new definition here; I think I found
1986 the value it used to have. Doc fixes, too.
1988 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
1990 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
1991 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
1992 Lord's implementation of structs, allowing for tail arrays as
1993 described in the manual. Also fixed some bugs. (Both the interface
1994 and the implementation should be improved.)
1996 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
1998 * print.c, print.h: Closures now print like #<procedure foo (x)>.
1999 People who whish to see the source can do `(print-enable 'source)'.
2000 Removed #ifdef DEBUG_EXTENSIONS.
2002 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2004 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
2005 integer (assuming for now accepting an integer is a good thing).
2007 * error.c, fports.c: replace use of %S in lgh_error args with %s.
2008 %S will be used instead for write'ing arguments.
2010 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
2011 asserts. fix a few other asserts.
2012 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
2013 scm_uniform_vector_ref, scm_array_set_x,
2014 scm_dimensions_to_unform_array): change args in
2015 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
2016 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
2017 scm_substring_fill_x): likewise.
2018 gsubr.c (scm_gsubr_apply): likewise.
2019 eval.c (SCM_APPLY): likewise.
2021 * eval.c (4 places): replace scm_everr with lgh_error or
2024 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
2025 scm_memory_error): new procedures.
2026 scm_everr: deleted. can use scm_wta, dropping first two args.
2027 scm_error: convert NULL subr to SCM_BOOL_F.
2029 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
2032 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
2035 * error.c, error.h: new error keys: scm_arg_type_key,
2036 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
2038 scm_wta: reimplement using lgh_error instead of scm_everr.
2040 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
2042 * gdbint.c: scm_lread now has one more argument.
2044 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
2045 scm_port_\1; Added mutator scm_set_port_filename_x (used when
2046 loading source from non-file ports, which, e. g., happens when
2047 using the Emacs interface).
2049 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
2052 * read.c: Added code for recording of positions of source code
2053 expressions; New functions: recsexpr, scm_lreadrecparen;
2054 _scm_make_srcprops --> scm_make_srcprops
2055 (scm_flush_ws): Removed updating of positions counters. This work
2056 is already done by scm_gen_getc
2058 * read.h: Added prototype for scm_lreadrecparen
2060 * print.c: Added #include "alist.h"
2062 * eval.c: Added #include "hash.h"
2064 * eq.c: Added #include "ramap.h"
2066 * options.c: Documentation fixes.
2068 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
2069 (scm_init_srcprop): Adjusted size of initial source-whash. Name
2070 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
2071 --> scm_make_srcprops
2073 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
2074 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
2075 function calls in the definition of the whash access macros.
2077 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
2079 * init.c (scm_boot_guile): Add level of indirection to
2080 scm_boot_guile_1() to ensure that stack base pointer is properly
2081 initialized. There was no guarantee that variable i was the
2082 highest/lowest variable on stack (i.e. the call frame of
2083 scm_boot_guile was not completely protected from gc).
2085 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
2087 * ports.h (scm_port_table): put back file_name, it will be used to
2088 support debugging. Undo related changes in fports.c, ioext.c,
2091 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2093 * ports.h (scm_port_table): remove file_name member for now, it seems
2095 * fports.c (scm_open_file): don't set file_name in PTAB.
2096 (prinfport): don't use file_name in PTAB.
2097 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
2098 * ports.c (scm_add_to_port_table): don't intialize file_name.
2099 (scm_port_file_name): remove for now.
2100 * gc.c (scm_gc_mark): don't mark PTAB file_name.
2102 * fports.h (scm_mkfile): prototype deleted.
2103 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
2105 * debug.c, unif.c: use scm_out_of_range instead of
2106 wta for range errors (ASSERT still needs work).
2108 * error.c, error.h (scm_out_of_range): new procedure.
2110 * error.c, error.h (scm_out_of_range_key): new key.
2112 * posix.c (scm_sync): #else was missing.
2114 * error.c, error.h: append _key to names scm_num_overflow and
2117 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
2118 of consing an empty list.
2119 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
2120 of macros, saves code and string space.
2121 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
2122 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
2123 lower case. Rename scm_syserror_m to scm_syserror_msg.
2124 error.h: prototypes for new procedures.
2126 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
2128 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
2130 * error.c, error.h: setup scm_num_overflow key.
2132 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
2133 Remove definition of SCM_OVSCM_FLOW.
2135 * fports.c (scm_open_file): use SCM_SYSERROR_M.
2137 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
2138 explicit message and args.
2140 * error.c, error.h, __scm.h: change system_error_sym to
2143 * error.c (system_error_sym): remove leading %% from the Scheme name
2146 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
2148 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2150 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
2151 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
2152 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
2153 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
2154 renamed. (These were introduced by unsupervised name
2157 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2159 * print.c: Added code for detection of circular references during
2160 printing. (init_ref_stack, grow_ref_stack): New functions. Added
2161 a hook for printing of closures (accessible via print options).
2162 This leads to a split of calls to scm_iprin1 into two classes:
2163 elementary print operations (e. g. the code which prints a smob)
2164 still use scm_iprin1 while top level calls (like scm_display) use
2165 scm_prin1. scm_prin1 begins by clearing the data structure used
2166 to record reference information.
2168 * print.h: Added declarations of scm_prin1 and scm_prlist.
2170 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
2172 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
2174 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
2176 * error.c (err_head): scm_iprin1 --> scm_prin1
2178 * debug.c: Adjusted header comment.
2182 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2184 * strerror.c: Doc fix.
2186 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2188 * gdbint.c (gdb_read): Now possible to run during GC.
2189 (unmark_port, remark_port): New functions.
2191 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
2193 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
2194 of allocating a new string object. Also, increase size by
2195 the factor 2 instead of 1.5.
2197 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
2199 * __scm.h (SCM_P): Corrected to run under traditional C.
2201 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
2204 * async.c: Calls to scm_sysintern corrected.
2206 * async.h (scm_async_clock): Redundant declaration removed.
2208 * continuations.c (scm_dynthrow): Redundant declaration removed.
2210 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
2211 Definition typos corrected.
2213 * debug.h: Missing declarations of functions in debug.c added
2216 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2217 Missing declarations to functions in eval.c added.
2219 * filesys.c: Possibly uninitialized variable rv.
2221 * gc.h (scm_object_addr, scm_unhash_name): Missing
2222 declarations of functions defined in gc.c added.
2224 * genio.c: Possible typos str_data -> wstr_data. ???
2226 * genio.c: Possibly unintended shadowing of local variable
2227 `int c' (gotos out of scope of inner `c'). ???
2229 * init.c: Uninitialized `SCM last' may be used.
2231 * ioext.h: (scm_sys_isatty_p): Typo.
2233 * list.h (scm_list_head): Missing prototype for function in
2236 * numbers.c (scm_two_doubles): Changed from extern to static
2237 (is used only within numbers.c).
2239 * numbers.h: Repeated declarations removed.
2241 * ports.h (scm_close_all_ports_except): Declaration for the
2242 function defined in ports.c added.
2244 * posix.h: Missing declarations added.
2246 * procs.h (scm_make_subr_opt): Missing declaration added.
2248 * socket.h (scm_sys_gethost): Missing declaration added.
2250 * socket.h: Redundant declarations removed (they are in fdsocket.h).
2252 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
2253 Missing declarations added.
2255 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
2257 * struct.c: Uninitialized variable `SCM answer' may be used.
2259 * unif.c (l2ra): Declaration prototype.
2261 * unif.c (scm_array_equal_p): Dummy definition removed (it is
2262 defined in ramap.c).
2264 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
2265 Redundant declarations removed (they are in ramap.h).
2267 * variable.h (scm_make_udvariable,
2268 scm_make_undefined_variable): Declaration corrected to
2269 correspond variable.c.
2271 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
2272 Missing declarations added.
2274 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
2276 * Makefile.in (distclean): Don't forget to delete fd.h.
2278 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2280 * fd.h.in, tags.h: Trivial cleanups.
2282 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
2283 marksweep.h just declared functions from gc.c.
2284 * gc.h, libguile.h: Don't #include "marksweep.h".
2285 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2286 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
2287 dependencies updated.
2289 * libguile.h: Don't #include "files.h"; it's been deleted.
2291 * files.c (scm_sys_delete_file): Moved to filesys.c.
2292 File is now empty; deleted.
2294 * filesys.c: scm_sys_delete_file is now here. Remove
2295 #if's; they seem to rely on remnants of an old portability
2296 regimen. If the problems come up again, solve them properly,
2297 using autoconf. Specifically: Don't test M_SYSV, and #define
2298 remove to be unlink if it's #defined; don't use remove just
2299 because HAVE_STDC_HEADERS is #defined.
2300 * filesys.h: Add declarations for scm_sys_delete_file.
2301 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2302 files.o, files.h, files.c, and files.x.
2303 * init.c: Don't #include "files.h", and don't call scm_init_files.
2305 Use SCM_P instead of PROTO; the latter intrudes on the user's
2307 * params.h: Deleted; definition of SCM_P moved to...
2308 * __scm.h: ... here, where it replaces PROTO macro.
2309 * libguile.h, smob.h: Don't #include "params.h".
2310 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
2311 smob.h: Fix prototypes accordingly.
2312 * Makefile.in: Update dependencies.
2313 (inner_h_files): Remove params.h.
2315 * gc.c: #include "gc.h"; every module should include its header,
2316 to let the compiler cross-check the declarations against the
2319 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2320 simpos.h: #include "libguile/__scm.h".
2322 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2324 * init.c: Don't forget to #include smob.h and init.h.
2325 * Makefile.in: Dependencies updated.
2327 * smob.h: Use PROTO instead of #if __STDC__.
2329 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2331 * __scm.h: Doc fixes.
2333 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2334 <angles>; this allows `make depends' to work properly.
2336 * libguile.h: #include smob.h and pairs.h before the others; they
2337 define typedefs used by other headers.
2339 C files should #include only the header files they need, not
2340 libguile.h (which #includes all the header files); the pointless
2341 recompilation was wasting my time.
2342 * Makefile.in (all .o dependency lists): Regenerated.
2343 * libguile.h: Don't try to get a definition for size_t here...
2344 * __scm.h: Do it here.
2345 * _scm.h: Since this is the internal libguile header, put things
2346 here that all (or a majority) of the libguile files will want.
2347 Don't #include <libguile.h> here; that generates dependencies on
2348 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2349 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2350 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

2447 * weaks.c: Get "weaks.h".
2449 * stackchk.h: #include "libguile/debug.h",
2451 * print.h, read.h: #include "options.h", since everyone who uses
2452 either of these files will need that.
2454 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2455 anyone who uses this file will need them to define the smob
2456 printing functions. Also, get markers.h, since people will need
2457 to #define the mark functions.
2459 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2460 * ports.h: ... to here.
2462 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2463 don't rely on archaic C default type rules.
2465 * fports.h: #include "libguile/ports.h", since you need that in
2466 order to parse this.
2468 * genio.h: #include "libguile/print.h", because you need that to
2469 parse this; don't bother #including "ports.h", since print.h gets
2472 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2474 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2475 this; it's now a reference to an element of *scm_root.
2477 * debug.h: Don't #include "options.h"; the compiler won't be able
2478 to find that once the headers are installed; instead, #include
2479 "libguile/options.h".
2480 * gc.h: Same, with marksweep.h.
2481 * mbstrings.h: Same, with symbols.h.
2482 * scmhob.h: Same, with _scm.h.
2483 * smob.h: Same, with params.h.
2485 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2486 C files; there's no need for this, and it forces recompilations
2489 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2491 * error.c (scm_error): declare scm_error_callback.
2493 * error.h: prototype for scm_error_callback.
2495 * __scm.h: define lgh_error.
2496 (SCM_SYSERROR): redefine using lgh_error.
2498 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2500 * error.c (scm_error): new procedure.
2502 * error.h: prototype for scm_error.
2504 * Makefile.in (install): install scmconfig.h from the current
2505 directory, not $(srcdir).
2507 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2509 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2510 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2511 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
2512 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
2513 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
2514 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2515 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2516 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2517 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2518 vports.h, weaks.h: #include "libguile/__scm.h", not
2519 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2520 dependencies are within libguile properly.
2522 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2524 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2525 when scmconfig.h doesn't exist.
2527 * load.c (scm_sys_try_load): Correct spelling.
2529 * feature.c (scm_loc_features): Make this static.
2531 * Makefile.in (libpath.h): Omit trailing slash from path. We
2532 shouldn't require it of users, so why put it here?
2534 Move code to initialize and search %load-path from ice-9 to C
2535 code, so we can use the load-path to find the ice-9 boot code;
2536 this makes it easier to run Guile without installing it. See
2537 corresponding changes in guile/Makefile.in.
2538 * feature.c: Move stuff concerned with the load path to load.c.
2539 (scm_compiled_library_path): Deleted.
2540 Don't #include libpath.h here.
2541 * feature.h: Don't mention scm_compiled_library_path.
2542 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2543 <sys/stat.h>, and <unistd.h> (if present).
2544 (R_OK): #define if the system hasn't deigned to.
2545 (scm_loc_load_path): New variable.
2546 (scm_init_load_path, scm_sys_search_load_path,
2547 scm_sys_try_load_path): New functions.
2548 (scm_init_load): Initialize scm_loc_load_path to point to the
2549 value cell of the Scheme %load-path variable.
2550 * load.h: Add declarations for scm_sys_search_load_path,
2551 scm_sys_try_load_path.
2552 * init.c: Call scm_init_load_path.
2553 * Makefile.in (feature.o, load.o): Dependencies updated.
2555 * load.c, load.h: Rewrite using PROTO macro.
2557 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2559 * gc.c (scm_cellp): New function: C predicate to determine if an
2560 SCM value can be regarded as a pointer to a cell on the heap.
2562 * gc.h: Added declaration of scm_cellp.
2564 * gdb_interface.h: New file: The GDB interface header from the GDB
2567 * gdbint.c: New file: GDB interface.
2569 * gdbint.h: New file: GDB interface.
2571 * libguile.h: Added #include <libguile/gdbint.h>.
2573 * init.c (scm_boot_guile): Added scm_init_gdbint.
2575 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2576 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2577 found if object files and source are kept separate).
2579 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2581 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2583 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2585 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2586 TK_SRC_DIR; they're not relevant any more.
2588 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2589 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2591 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2593 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2594 search path, so we can find the <libguile/MUMBLE.h> headers.
2596 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2598 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2599 implicit in the .c.o rule.
2600 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2603 Put the library path in a header file, instead of passing it on
2604 the command line in every compilation.
2605 * Makefile.in (libpath.h): New target.
2606 (feature.o): Depend on libpath.h.
2607 (clean): Delete libpath.h.
2608 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2609 * feature.c: ... #include "libpath.h" here.
2610 * .cvsignore: Ignore libpath.h.
2612 Don't install the unwashed masses of Guile header files in the
2613 main #include path; put most of them in a subdirectory called
2614 'libguile'. This avoids naming conflicts between Guile header
2615 files and system header files (of which there were a few).
2616 * Makefile.in (pkgincludedir): Deleted.
2617 (innerincludedir): New variable; this and $(includedir) are enough.
2618 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
2619 (installed_h_files): Divide this up. Now this variable lists
2620 those header files which should go into $(includedir) (i.e. appear
2621 directly in the #include path), and ...
2622 (inner_h_files): ... this new variable says which files appear in
2623 a subdirectory, and are referred to as <libguile/mumble.h>.
2624 (h_files): List them both.
2625 (install): Create innerincludedir, not pkgincludedir. Put
2626 the installed_h_files and inner_h_files in their proper places.
2627 (uninstall): Corresponding changes.
2628 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2629 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2630 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
2631 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
2632 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
2633 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2634 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2635 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2636 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2637 vports.h, weaks.h: Find __scm.h in its new location.
2638 * __scm.h: Find scmconfig.h and tags.h in their new locations
2639 (they're both "inner" files).
2641 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
2643 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
2645 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2647 * posix.c: Doc fixes.
2649 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
2651 * socket.c: Don't include a prototype for inet_aton; just use a
2652 K&R style declaration, to avoid warnings but minimize the chance
2653 of conflicts with the system.
2655 On NextStep, <utime.h> doesn't define struct utime, unless we
2656 #define _POSIX_SOURCE before #including it.
2657 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
2658 * acconfig.h: New comment text for above CPP symbol.
2659 * configure.in: Call it.
2660 * posix.c: #define _POSIX_SOURCE if it seems necessary.
2662 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
2664 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
2665 testing for __EMX__.
2667 * posix.c: #include <libc.h>, if it exists.
2669 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
2670 don't even know if the latter exists.
2672 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
2673 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
2674 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
2676 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
2678 (scm_init_posix): Use them when initializing the Scheme constants
2681 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2683 * Makefile.in (libdir, includedir, bindir): Use the
2684 autoconf-supplied values, instead of deriving them ourselves.
2685 (pkgincludedir, datadir, pkgdatadir): New variables.
2686 (install, uninstall): Put the header files in a special
2687 subdirectory, not in the main search path.
2689 * Makefile.in (ALL_CFLAGS): Provide the proper value for
2690 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
2692 * Makefile.in (IMPLPATH): Deleted; never used.
2694 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
2695 on the Tcl/Tk source any more.
2696 (INCLUDE_CFLAGS): Remove references to the above.
2698 * Makefile.in (version.o): Corrected dependencies.
2700 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
2702 * libguile.h: #include "version.h"
2704 * init.c (scm_boot_guile): Call scm_init_version.
2705 * gscm.c (gscm_run_scm): Call scm_init_version.
2707 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
2708 GUILE_VERSION): AC_DEFINE these.
2709 (acconfig.h): #undef the above symbols.
2711 * Makefile.in (libobjs): Add version.o.
2712 (installed_h_files): Add version.h.
2713 (c_files): Add version.c.
2714 (gen_c_files): Add version.x.
2715 (version.o): New rule.
2716 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
2717 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

2726 weaks.o): Add version.h to dependency lists.
2727 (markers.o): Remove duplicate rule.
2729 * version.h: New file.
2731 * version.c: New file.
2733 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2735 * symbols.c (scm_strhash): scm_downcase is now a function, not an
2736 array; use it appropriately. Since GCC is quite happy to
2737 subscript functions, it never warned us about this; we should use
2738 -Wpointer-arith in the future. I guess we never tested
2741 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2743 * socket.c: Doc and copyright fixes.
2745 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2747 * debug.c: Fixed and improved gdb support.
2749 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2751 * socket.c: Added declaration of inet_aton to avoid compiler
2752 warning. (Hope this solution is correct.)
2754 * stime.c: Added declaration of ftime. (This is missing in
2757 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
2759 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2761 * Makefile.in (c_files): add strerror.c.
2763 * strerror.c: new file from Emacs' sysdep.c.
2764 maybe configure should also check for sys_errlist.
2766 * configure.in (AC_REPLACE_FUNCS): add strerror.
2768 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2770 * debug.c (scm_init_debug): Added initialization for
2771 scm_evaluator_traps.
2773 * debug.h, debug.c: Various name changes.
2774 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
2775 "debug-options-interface". See commentary in options.c.
2777 * options.h, options.c: Options now have documentation strings.
2778 Also added a long explanatory commentary.
2780 * eval.c, print.h, print.c, read.h, read.c: Modifications to
2783 * gscm.c, init.c, root.c, throw.c: Bug fixes:
2784 last_debug_info_frame is now updated in all cases.
2786 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
2789 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2791 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
2792 Added option STACK_CHECKING.
2794 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
2796 * Makefile.in: Added {debug,options,srcprop}.{h,c}
2798 * __scm.h: Removed symbols for debugging support.
2800 * acconfig.h: Added symbols for debugging support.
2802 * configure.in: Added user option for debugging support.
2803 --enable-debug will include the debugging code into libguile.a.
2805 * continuations.c (scm_make_cont): Enlarged the #if 0 around
2806 scm_relocate_chunk_to_heap.
2808 * debug.c: New file: low-level debugging support. It also
2809 includes support for debugging with gdb. (The extensions to gdb
2810 are written by Per Bothner at Cygnus.)
2812 * debug.h: New file: low-level debugging support.
2814 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
2815 argument pairs. Extensive modifications to the debugging
2816 evaluator. Added "SECTION:" commentaries to clarify what happens
2817 when, during double compilation. Renamed EVALIMP --> EVALIM.
2818 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
2819 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
2820 the beginning of the file. New procedure: scm_unmemocopy.
2821 Added some global state variables needed by the debugging
2822 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
2823 check_entry, check_apply, check_exit, debug_options and
2824 evaluator_traps. New acro: undefine.
2826 * eval.h: Renamed EVAL --> XEVAL.
2828 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
2829 --> scm_make_weak_key_hash_table.
2831 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
2832 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
2834 * libguile.h: Conditionally include debug.h
2836 * objprop.c (scm_object_properties, scm_set_object_properties_x):
2837 scm_object_properties shouldn't return handle. `handle' now gets
2838 initialized in scm_set_object_properties_x. scm_object_properties
2839 doesn't any longer create an entry in scm_object_whash.
2841 * options.c: New file: handling of run time options.
2843 * options.h: New file: handling of run time options.
2845 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
2847 * print.c: New procedure: scm_print_options
2849 * print.h: Defines for print options.
2851 * read.c: New procedure: scm_read_options
2853 * read.h: Defines for reader options.
2855 * root.h: Added scm_source_whash among scm_sys_protects.
2857 * srcprop.c: New file: source properties.
2859 * srcprop.h: New file: source properties.
2861 * throw.c (jbsmob): Jump buffers are now correctly allocated.
2862 (Bug found by A. Green.)
2864 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2866 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2868 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
2870 * libguile.h: #include "objprop.h"; I guess this was forgotten.
2872 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
2873 and should be called by the final client.
2875 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
2877 * gc.h: Use the PROTO macro when declaring functions.
2878 * gc.c: Use the PROTO macro when declaring static functions.
2879 Remove the CPP hair around function definitions.
2881 * gc.c (scm_init_storage): Initialize scm_asyncs.
2883 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
2884 preprocessor symbol; "__scm.h" is where it might get #defined.
2885 * __scm.h: Similar: #include <scmconfig.h> before testing
2888 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
2890 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
2892 * init.c (scm_boot_guile): Add init_func argument; call
2893 (*init_func) instead of calling scm_appinit; it's ucky to
2894 hard-code names for the user's procedures.
2895 * init.h (scm_boot_guile): Adjust declaration.
2897 * __scm.h (PROTO): New macro, for declaring functions with
2900 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
2901 eliminate all the __STDC__ conditionals.
2902 (scm_boot_guile): Add declaration.
2903 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
2904 Remove __STDC__ conditionals around function definitions; the
2905 declarations in init.h will provide the same information, more
2908 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
2909 complain about it in the error message; the error message is
2910 adequate without that note, and there's nothing the user can do
2913 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
2915 * Makefile.in (ancillary): Drop def.sed.
2917 * posix.c (scm_init_posix): Use numeric values, rather than
2918 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
2919 F_OK. The symbols aren't available on some systems, and I'm
2920 pretty sure their values are fixed by common widespread practice.
2921 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
2923 More functions unavailable on some systems.
2924 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
2925 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
2927 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2928 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
2929 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
2930 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
2931 stub that signals an error as the #else.
2933 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
2935 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
2937 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
2939 * unif.c: include ramap.h.
2941 * read.c (endif): case_insensative_p renamed case_insensitive_p.

2945 * ports.c: include sys/ioctl.h.
2947 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
2949 * configure.in: check for sys/ioctl.h.
2951 * ports.c: include <malloc.h> not "malloc.h".
2953 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2955 * fports.c: remove ttyname and tmpnam declarations.
2957 * posix.c: fewer ttyname declarations.
2959 * fports.c: include <string.h> not "string.h".
2961 * init.c, ioext.c: include string.h and unistd.h.
2963 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2965 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
2966 genio.c, simpos.c, vports.c: include string.h.
2968 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
2970 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
2972 (scm_addr_buffer_size): change type from scm_sizet to int.
2973 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
2974 from scm_sizet to int.
2976 * error.c: include unistd.h.
2978 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
2981 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
2983 * __scm.hd, def.sed: deleted.
2985 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
2987 Changes for NeXT, suggested by Robert Brown.
2988 * configure.in: Call AC_TYPE_MODE_T.
2989 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
2990 NeXT. Put header file list in alphabetical order.
2991 * configure, scmconfig.h.in: Regenerated.
2992 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
2994 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
2997 * acconfig.h: New file, providing documentation for the CPP
2998 symbols defined in configure.in
2999 * acconfig-1.5.h: Removed; superceded by the above.
3001 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
3003 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
3005 * fports.c (scm_open_file): don't return #f, throw error.
3007 * ioext.c (fileno): renamed from %fileno.
3008 (soft-fileno): deleted.
3010 * ports.c (scm_port_revealed): don't need to check for -1 from
3012 (scm_set_port_revealed_x): return unspecified, not #f.
3014 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
3016 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
3018 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
3020 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
3022 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3024 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
3025 This is necessary on Ultrix, and doesn't hurt portability.
3027 * Makefile.in (dist-dir): New target, implementing a new dist system.
3028 (installed_h_files): Put in alphabetical order.
3029 Remove duplicate entries for markers.h and unif.h.
3030 (c_files): Remove duplicate entries for markers.c.
3031 (ancillary): Renamed from anillery; all uses changed. Remove
3032 PLUGIN; it's a directory, and needs special treatment in dist-dir.
3033 Remove all the ../doc/* files; doc/Makefile.in handles that.
3035 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
3037 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
3038 every if must have an else, or else the whole command has a
3039 non-zero exit code whenever the if's condition is false.
3041 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
3043 * posix.c: include string.h.
3045 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
3047 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
3050 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
3051 Remove leading % from scheme names.
3052 Do not return error values, call SCM_SYSERROR or similar.
3054 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
3056 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
3058 * struct.c (scm_init_struct): new file.
3060 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
3062 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
3063 (scm_list_head): added list-head for rapidly chopping argument
3064 lists off of longer lists (and similar).

3069 handle for obj, not the handle itself.
3071 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
3073 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
3074 weak hash tables last of all marking to avoid an obscure gc bug.
3075 WARNING: circular lists stored in a weak hash table will hose us.
3077 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
3079 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
3080 new functions similar to scm_substring_move_left_x and
3081 scm_substring_move_right_x.

3090 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
3092 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
3094 * strports.c (scm_strprint_obj): convenience function. C for
3095 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
3097 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
3098 removed to a separate library
3100 * init.c (scm_boot_guile): copied from guile-tcl.c.
3101 Initialization specific to tcl interpreters removed.
3103 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
3105 * ports.c (scm_ports_prehistory): size malloced here doesn't
3106 matter so long as it is non-0 (got rid of "* 4").
3108 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
3110 * gscm.h: gscm_mkarray eliminated (presumably was not being used
3111 since its definition was bogus).
3113 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
3115 * mallocs.[ch]: back again (for rx at least).
3117 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
3119 * ports.c: removed functions relating to the mapping between ports
3120 and descriptors. (That stuff is unix-specific and should be collected
3121 in a separate library).
3123 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
3124 (Tom Mckay@avanticorp.com)
3126 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
3128 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
3129 handled correctly (SCM_FREEP was applied to them) -- test for
3130 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
3131 being overwritten with #f. (brown@grettir.bibliotech.com)

3150 Generalized assoc and hash-table functions.
3151 Factored pairs.c into multiple files.

3175 (possibly triggering gc) before setting the tag of the corresponding
3178 * pairs.c (scm_delq_x): never throw an error.
3180 * vectors.c (scm_make_vector): made the default vector fill argument
3181 into '() (much more useful than the previous value, "#unspecified")

3185 * ports.c (scm_add_to_port_table): Added fields
3186 to port table entries: file_name, line_num, col.
3187 Update these in open_file, gen_getc and gen_ungetc.
3188 Added procedures to access those fields.
3190 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
3192 * procs.c (scm_make_subr_opt): new entry point for making

3222 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
3224 * feature.c (scm_compiled_library_path): moved here from repl.c.
3225 This file is for stuff relating specifically to Scheme libraries
3228 * eval.c (scm_m_define): don't give warning about redefinition, don't
3231 NOTE: this should throw a resumable exception with parameters --
3232 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
3234 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
3236 * error.c: scm_warn eliminated.

3256 because it changes size.
3258 (stputc stwrite): check/change the strings length with interrupts
3261 * objprop.c (scm_set_object_property_x &c): use the generic
3262 hashing functions and be threadsafe.

3265 (per suggestion jaffer@gnu.ai.mit.edu).
3267 * mbstrings.c (scm_multi_byte_string): guard against argument list
3270 * strings.c (scm_make_string): loop cleanup

3298 initialization to fix a race condition.
3300 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
3301 object, not in a global.
3302 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)

3323 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
3324 set the multi_byte flag correctly in symbols. This is wrong.
3325 intern_obbary_soft and msymbolize should take an extra parameter.
3326 Also, weird multibyte symbols don't print correctly.
3327 The weird symbol syntax is also a bit bogus (emacs doesn't quite
3330 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
3332 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
3333 use the system symhash. == #t means create an uninterned symbol.
3335 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
3337 * strings.c (scm_make_shared_substring): build'em.
3338 It might better to keep a table of these and use one
3339 less cons-pair per shared-substring.

3409 * lvectors.c (scm_get_lvector_hook):
3410 In guile-ii, the lvector code was broken. It was fixed in guile-iii.
3411 It seems to me like if it is broken again in guile-iv...Here is a patch.
3412 "! || (LENGTH (keyvec) == 0))"
3413 (From: Mikael Djurfeldt <mdj@nada.kth.se>)
3416 * gscm.c (gscm_sys_default_verbosity):
3417 incorrectly declared for non-__STDC__
3418 (Tom_Mckay@avanticorp.com)

3421 to make it easier to port to systems that use
3422 more than a single structure field to hold a descriptor.
3424 * debug.c (change_mode): Avoid GNUCism "int foo[n];"
3425 Give a warning, not an error, for unrecognized modes.
3427 * eval.c (SCM_CEVAL):
