1 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
4 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
6 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
7 cpp_err_symbols.c): Corresponding changes.
8 * Makefile.in: Regenerated.
10 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
12 * posix.c (scm_putenv): don't check HAVE_PUTENV.
13 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
14 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
15 * putenv.c: new file, from sh-utils 1.12.
17 * posix.c (scm_environ): use malloc in place of scm_must_malloc
18 since allocation isn't for Scheme objects.
19 (scm_putenv): copy strings before placing in the environment.
21 * stime.c (scm_current_time): throw an error if time returns -1,
22 instead of returning #f.
23 (scm_get_internal_real_time, scm_get_internal_real_time): use
24 scm_long2num for return value instead of SCM_MAKINUM.
26 * stime.h: prototypes updated.
28 * stime.c (scm_time_in_msec): apparently unused, deleted.
30 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
32 * configure.in: check for gettimeofday.
34 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
35 which may be more usefully portable than a gettimeofday interface.
37 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
39 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
41 * Makefile.in: Regenerated.
43 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
45 * stime.c (filltime): recovered static procedure.
46 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
49 * posix.h: add prototype for scm_close_pipe, remove prototypes for
50 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
52 * * posix.c (scm_mknod): split the mode argument into type and perms
53 arguments, like the extra fields returned by stat.
55 * fports.c (scm_pipob): set the close, free and print procedures.
56 (scm_close_pipe): new procedure.
58 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
59 define them in boot-9.scm
61 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
63 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
64 wan't defined. Don't include fd.h.
66 * Previously fd.h was regenerated whenever configure was run,
67 forcing a couple of files to be recompiled.
69 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
70 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
71 Check for _fileno as well as _file.
73 * ioext.c: don't fd.h.
74 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
77 * Change the stratigy for getting information about errno
78 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
79 generating lists of symbols during the build process, which will
80 not always work, include comprehensive lists in the distribution.
81 To help keep the lists up to date, the "check_signals" and
82 "check_errnos" make targets can be used.
84 * configure.in: don't check for a command to extract errno codes.
85 * Makefile.am: update file lists, remove errnos.list and errnos.c
86 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
88 (CLEANFILES): remove errnos.c and errnos.list, add
89 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
90 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
91 * errnos.default: deleted.
92 * cpp_signal.c: new file.
93 * cpp_errno.c: renamed from errnos_get.c.
94 * cpp_err_symbols, cpp_sig_symbols: new files.
95 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
96 * error.c (scm_init_error): #include cpp_err_symbols instead of
98 * posix.c (scm_init_posix): don't intern signal symbols. #include
101 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
103 * strop.c (scm_i_index): allow the lower bound to be equal to the
104 length of the string, so a null string doesn't always give an error.
106 * posix.h: new prototypes.
107 * posix.c (scm_status_exit_val, scm_status_term_sig,
108 scm_status_stop_sig): new functions, as in scsh. They break down
109 process status values as returned by waitpid.
111 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
113 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
114 configure doesn't know about it.
116 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
118 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
120 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
121 which defines C variables with global linkage.
123 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
125 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
128 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
130 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
131 has time to check why this doesn't work well with continuations.
133 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
135 * Fix shell syntax error; some shells won't tolerate
136 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
138 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
140 * posix.c (scm_uname): throw an error if uname fails instead
143 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
145 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
148 * async.c (scm_ints_disabled): definition moved from error.c.
150 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
152 * acconfig.h: Removed PACKAGE.
154 * scmconfig.h.in: Regenerated.
156 * snarf.h: g++ says it's non-portable not to specify the first
157 argument in a varargs declaration. I introduced the first
158 argument by using preprocessor conditionals.
160 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
162 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
163 (scm_freopen): use RO string macros for filename and modes.
164 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
166 * posix.c (scm_getgrgid): simplify conversion of name to C string.
167 (scm_mknod): use RO string macros for path.
169 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
170 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
172 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
173 use SCM_ROSTRINGP and SCM_ROCHARS.
175 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
177 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
180 * ramap.c (scm_ra_matchp, scm_ra_matchp, scm_array_fill_int, racp,
181 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
182 support for byte vectors.
184 * print.c (scm_iprin1): Limit number of vector elements printed
185 according to pstate->length.
187 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
189 * backtrace.c (scm_display_error_message): don't segv if message
192 * error.h: prototype for scm_error_scm.
194 * error.c (scm_error_scm): new procedure, reimplements scm-error
195 in C and uses scm_error.
197 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
199 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
200 pointer to the Scheme variable read-hash-procedures and intern it
201 in scm_init_read. Modify scm_read_hash_extend and
202 scm_get_hash_procedure to use the pointer.
204 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
206 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
207 (SCM_KEYWORD_STYLE): defined.
209 * read.c (scm_read_opts): add a keywords option. This isn't a
210 boolean option, in case someone wants to add support for DSSSL
212 Setup scm_keyword_prefix symbol.
213 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
215 * I've left keyword support disabled by default, since it doesn't
216 seem to break the module system and it gives R4RS standard behaviour.
217 It can be reactivated with (read-set! keywords 'prefix).
219 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
221 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
222 before constructing arbiter.
224 * eval.c (scm_m_define): Bugfix: Check that the object is a
225 closure before setting the procedure property!
227 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
229 * ports.c: Removed `ungetc-char-ready?'.
231 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
233 * read.c (scm_init_read): intitialise scm_read_hash_procedures
234 (idea from Mikael: make it a pair so scm_permanent object only
236 (scm_read_hash_extend): don't call scm_permanent_object.
237 (ideas from Mikael): if chr is already in the list, replace its
238 procedure instead of appending it again. If proc is #f, remove
240 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
242 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
244 * gdbint.c (gdb_read): update scm_lreadr usage.
246 * load.h: update prototypes.
248 * load.c (scm_primitive_load, scm_read_and_eval_x,
249 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
251 * read.h: add prototype for scm_read_hash_extend. Change args for
254 * read.c (scm_read_hash_procedures): new variable.
255 (scm_read_hash_extend): new procedure.
256 (scm_get_hash_procedure): new procedure.
257 * (scm_lreadr): use scm_get_hash_procedure instead of an argument
258 for extended # processing.
259 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
260 scm_read_token): remove case_i, sharp arguments. Change callers.
262 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
264 * read.h (SCM_N_READ_OPTIONS): increase to 3.
265 (SCM_CASE_INSENSITIVE_P): define.
267 * read.c: add case-insensitive option to scm_read_opts.
268 * (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
269 to determine whether to convert symbol case.
270 (default_case_i): definition removed.
271 * read.c (scm_read_token): if case_i, downcase ic before doing
274 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
276 * configure.in: Added configuration option `guile-debug'.
277 Configure with --enable-guile-debug if you want a bunch of extra
278 functions used for debugging when developing Guile.
280 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
282 * procs.c (make-cclo): New undocumented debugging procedure: Make
283 compiled closure with internal procedure PROC and length LENGTH.
284 Only compiled if GUILE_DEBUG is defined.
286 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
288 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
290 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
292 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
293 with 3 or more args internally to the evaluator.
295 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
297 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
298 with 3 or more args internally to the evaluator. This is mainly
299 because we don't want to pass entry and exit points of the
300 debug support twice, but it also seems to increase the speed of
301 the evaluator for such calls (e. g. (+ 1 2 3)).
303 * * backtrace.c (scm_display_application): New procedure:
304 display-application; Set fancy printing parameters individually
305 for different types of display (backtrace, error, application).
306 (These should of course be customizable!)
308 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
309 clear the CHECK-flags.
311 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
313 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
315 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
317 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
318 from pairs with a GLOC in the car.
320 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
321 otherwise `symbol-hash' will behave badly.
322 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
323 we get segmentation fault!
325 * * symbols.c: Added #include "weaks.h". New functions:
326 `builtin-bindings' and `builtin-weak-bindings'. (These will be
327 moved to an extraneous library when we split libguile.)
329 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
331 * filesys.c (scm_stat): stat now takes fport arguments too as
332 documented in the manual.
334 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
336 * debug.c (scm_single_step): Bugfix: Call continuation with
337 scm_call_continuation instead of throwing to it.
339 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
341 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
342 argument wasn't declared to be optional.
344 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
346 * stime.c (scm_init_stime): Add feature "current-time".
348 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
350 * throw.h: prototype for scm_exit_status.
351 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
352 args to derive an exit status. Allows (quit) to work from a
354 (scm_exit_status): new function.
357 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
359 * eval.c (scm_deval): Removed some old code.
360 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
362 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
365 * symbols.c (msymbolize): Bugfix: Must initialize property list to
368 * procs.c: Introduce the existent C function scm_thunk_p at the
369 Scheme level as well.
371 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
373 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
374 used from C to easily lookup the value of a symbol in the current
377 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
379 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
380 scm_init_unif in this file. This will also fix a previous problem
383 * configure.in: Added AM_MAINTAINER_MODE
385 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
387 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
390 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
392 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
393 source files that are not always included in libguile but should
394 have their dependencies calculated by automake. This variable is
395 recognized by automake, no further magic is needed.
396 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
397 to deal exclusively with *.lo files, as it seems. The *.o files
398 are built automatically when the corresponding *.lo file gets
401 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
403 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
406 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
408 * unif.c (scm_array_set_x): minor change to argument error checking.
410 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
412 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
413 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
414 They should only be included in the library at configure.in's
416 (libguile_la_LDADD): Include the appropriate .lo files here.
417 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
418 so we know when to build them (and their .lo bretheren).
419 * configure.in (LIBLOBJS): New substituted variable. We let
420 configure decide which .o files to include in LIBOBJS, and then
421 put the corresponding list of .lo files in LIBLOBJS. The latter
422 is what we pass to libtool.
423 * Makefile.in, configure: regenerated.
425 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
427 * symbols.c (scm_sysintern0): New function. Contains the core of
428 old scm_sysintern but doesn't take a second value argument.
429 (scm_sysintern): Now uses scm_sysintern0.
430 (scm_sysintern_no_module_lookup): Renamed to
431 scm_sysintern0_no_module_lookup and doesn't take a second value
434 * symbols.h (scm_sysintern0: Added declaration.
436 * options.c (scm_init_opts): Use scm_sysintern0 instead of
437 scm_sysintern when interning option keys. Otherwise we risk
438 destroying the values of already interned variables.
440 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
441 scheme-level boolean (use SCM_NFALSEP).
443 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
445 (scm_backtrace): New function. (C version of old function from
446 boot-9.scm) Motivation: Make it possible to display backtraces
447 without depending on boot-9.scm. (I'm uncertain if this
448 motivation is good enough...)
450 * root.h (scm_root_state): Add member the_last_stack_var.
451 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
453 * root.c (mark_root): Mark scm_the_last_stack_var.
455 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
458 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
460 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
461 1. mark_lazy_catch didn't mark the smob.
462 2. Both functions above have standard variants:
463 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
464 free_lazy_catch --> scm_free0.
466 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
468 * throw.c (scm_internal_lazy_catch): New function.
469 (scm_lazy_catch): Rewritten to use it.
470 (scm_ithrow): Handle the new lazy catch representation.
471 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
472 that doesn't have a jmpbuf is a lazy catch clause.
473 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
474 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
475 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
477 (scm_init_throw): Register the new lazy-catch smob type.
478 * throw.h (scm_internal_lazy_catch): decl for new function.
480 * throw.c (scm_internal_catch): Doc fixes.
482 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
483 configure.in. Including this might cause problems if applications
484 that link against libguile include their own copies of alloca, but
485 if they're using autoconf, they should be adding libguile to LIBS
486 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
487 the copy in libguile, and things will be okay. (I think.)
489 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
491 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
493 strop.h: move prototypes too.
495 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
497 * posix.c (scm_init_posix): don't intern EINTR since it's now done
500 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
501 etc. I deleted them from filesys.c long ago, but didn't
502 notice they were here too (although ineffective since
503 sys/stat.h wasn't included).
505 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
507 * eval.c: Don't define alloca in GCC case. gcc will automatically
508 use __builtin_alloca if appropriate.
510 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
512 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
513 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
514 that values of automatic variables are preserved. See comments
515 for safe_setjmp for details.
517 Change from Thomas Morgan:
518 * variable.c: Include eq.h.
519 (var_equal): New function.
520 (variable_smob): Use var_equal as the discriminator for variables.
522 * throw.c (s_throw): Remove extraneous declaration.
524 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
525 * eval.c: Add necessary CPP cruft to support that.
526 * configure, Makefile.in, scmconfig.h.in: regenerated.
528 Change from Thomas Morgan:
529 * procprop.c (scm_procedure_properties): Convert the Scheme
530 boolean returned by scm_procedure_p into a C boolean before using
531 it as a condition for SCM_ASSERT.
532 (scm_procedure_property): Likewise.
534 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
535 indications of Unixness.
538 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
540 * * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
542 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
544 * read.c (scm_lreadr): use scm_misc_error to improve one of the
545 "unknown # object" error messages.
547 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
548 (scm_i_index) and declare it static. Add a 'direction' argument
549 to indicate what way the search should go.
550 (scm_i_index): throw out-of-range error instead of wrong-type-arg
552 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
553 strop.h: remove scm_i_index, scm_i_rindex prototypes.
555 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
557 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
559 * * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
560 to avoid clash with various scsh forks.
562 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
564 The following two changes (ramap.c, throw.c) are motivated by the
565 apparent unportability of forward declarations of static arrays of
566 the form `static foo bar[];'.
568 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
569 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
571 * throw.c (scm_throw): Moved above scm_ithrow.
573 * options.h: Removed the extern declarations of scm_yes_sym and
574 scm_no_sym since these are static.
576 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
578 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
580 * Makefile.am: remove AWK=@AWK@.
581 Add a rule for generating errnos.list.
582 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
584 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
585 don't extract errnos, just set a variable (avoids the
586 need to recompile error.c just because configure is run.)
588 * unif.h: update prototypes.
589 * unif.c (scm_uniform_array_read,write): change the offset and
590 length arguments to start and end, for consistency.
592 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
594 * ioext.h: update prototypes.
595 * * ioext.c (scm_read_delimited_x): replaces scm_read_line and
596 scm_read_line_x, it's a more general procedure using an
597 interface from scsh. read-line and read-line! are now defined
599 * Note that the new read-line trims the terminator
600 by default, previously it was appended to the returned string. An
601 optional argument specifies how to process the terminator (scsh
602 compatible). For the old behaviour: (read-line port 'concat).
603 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
604 returns a pair, but is converted to multiple values if the scsh
607 socket.h: update prototypes.
608 * socket.c (scm_recvfrom): for consistency with other procedures,
609 take start and end as separate optional arguments.
610 * (scm_recv, scm_recvfrom): don't allow the second argument
611 to be a size, only a buffer. Change the scheme names to
612 recv! and recvfrom!. Don't return the buffer.
614 * ioext.h, posix.h: move prototypes too.
615 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
616 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
617 "read.h" and "unif.h".
618 * ioext.c: include "chars.h"
620 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
622 * dynl.c: The dynamic linking and module registration functions
623 are now defined even when dynamic linking is not available for the
624 host system. Some of their functionality can be done without
625 dynamic linking; when it's really needed, they throw errors.
627 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
629 * configure.in: Only define DYNAMIC_LINKING when one of the system
630 dependent functions is detected.
631 * dynl.c (scm_dynamic_func): New function to get the address of a
632 function in a dynamic object.
633 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
634 produced by scm_dynamic_func as the thing to call.
636 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
638 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
639 (scm_register_module_xxx, scm_registered_modules,
640 scm_clear_registered_modules): New functions.
642 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
644 * symbols.c (scm_sysintern): Renamed to
645 scm_sysintern_no_module_lookup.
646 (scm_sysintern): New function to take the place of the old
647 scm_sysintern. It uses the current toplevel lookup closure to give
648 the symbol its value. This is a temporary hack to put packages
649 like gtcltk into their own module.
650 (scm_can_use_top_level_lookup_closure_var): New variable to tell
651 us whether `scm_top_level_lookup_closure_var' has been initialized
653 * eval.c (scm_init_eval): Set it.
655 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
657 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
658 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
660 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
662 * (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
663 scm_sys_dup): deleted: FD capability will be added to other
665 * Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
666 scm_fd_free, fd_smob, scm_intern_fd.
667 * (scm_open): renamed from scm_sys_open. Return a port instead of
668 an FD object. Make the mode argument optional.
669 * (scm_sys_create): deleted, it's just a special case of open.
670 (scm_init_filesys): move interning of constants O_CREAT etc.,
671 here (were previously using SCM_CONST_LONG macro).
672 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
674 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
675 include "fports.h" and <stdio.h>
676 (scm_stat, scm_select): don't support FD objects.
678 * error.h: adjust scm_syserror_msg prototype.
679 * error.c (scm_syserror_msg): take an extra argument for errno.
680 Using the global value didn't always work, since it could be
681 reset by procedure calls in the message or args arguments.
683 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
684 I don't understand why the check was there (and what about the
687 * strop.c (scm_string_copy): allow shared substrings to be copied.
689 * unif.h: corresponding change to prototypes.
690 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
691 recognize two new optional arguments: offset and length. Allow
692 the port argument to be an integer (file descriptor, for scsh).
693 Include <unistd.h> for "read" prototype.
695 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
697 * socket.c: don't include filesys.h.
699 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
701 * Makefile.am: add AWK=@AWK@ (?)
703 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
705 Add a rule to generate errnos.c from errnos.
706 * error.c (scm_init_error): include errnos.c.
707 * errnos_cnvt.awk: new file, converts the list of errno codes to
709 * errnos_get.c: new file.
710 * errnos.default: new file, contains errnos to try if they can't
711 be extracted from errno.h.
712 * configure.in: if using GCC, try and extract errno codes from
716 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
718 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
719 * Makefile.am: Made libguile into a libtool library.
720 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
721 Set libtool_libs to indicate that libguile is a libtool library.
722 See guile/ChangeLog for details.
723 * .cvsignore: ignore "*.lo", the libtool library objects.
725 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
727 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
728 use htons in getservbyport argument.
730 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
732 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
733 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
736 * objprop.c (scm_object_property): No need to take the CDR of the
737 value returned by scm_object_properties, since Aug 20 change.
739 * configure.in: When checking for struct linger, #include
740 <sys/types.h> as well as <sys/socket.h>. I've never known
741 <sys/types.h> to cause any portability problems, and Solaris's
742 <sys/socket.h> needs it.
743 * configure: Rebuilt.
745 I think the Sun compiler has chosen a perverse way to interpret
746 ANSI declarations combined with K&R definitions. We'll
747 appease it a little bit. But when it invades France, we fight.
748 * print.c (scm_iprlist): Change 'tlr' argument to an int.
749 * print.h (scm_iprlist): Here too.
750 * numbers.c (scm_divbigdig): Change definition to match
751 declaration in numbers.h.
752 * unif.c (scm_makflo): Change definition to match declaration in
755 * init.c (scm_boot_guile): Don't return the value of
756 scm_boot_guile_1. This function doesn't return a value;
757 scm_boot_guile_1 doesn't return a value (or return at all).
759 * eval.c (unmemocopy): Add a semicolon to appease the Sun
762 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
763 compile. I have a feeling this function is a bad idea anyway ---
764 one should always test for features, not systems.
766 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
767 semicolons. Only pure luck kept this from being noticed earlier.
769 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
771 * socket.c (scm_recvfrom): Added missing semicolon.
773 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
775 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
776 the buffer and start and end positions for scsh networking
779 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
781 * configure.in: Revert previous change to this file; the problem
782 is due to transient automake weirdness.
783 * configure: Rebuilt.
785 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
786 PLUGIN/guile.libs. configure generates the latter from the former.
787 * Makefile.in: Rebuilt.
789 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
790 need this if we install scripts, like guile-snarf.
791 * configure: Rebuilt.
793 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
795 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
797 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
799 * socket.c (scm_addr_vector): fix faulty scm_listify.
801 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
803 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
804 style block comment is no longer considered an error.
806 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
808 * PLUGIN/guile.libs.in: New file.
809 * PLUGIN/guile.libs: Removed from repository.
810 * configure.in: Create PLUGIN/guile.libs from
811 PLUGIN/guile.libs.in. This is for including additonal libraries
812 needed for dynamic linking.
813 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
814 instead of PLUGIN/guile.libs.
816 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
818 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
820 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
821 occurrences of the given element from the list, not just the
822 first. This is how the Emacs Lisp functions behave, how the
823 analogous Common Lisp functions behave, and (I believe) how the
824 older Maclisp functions worked. I realize that this change may
825 break code, but it seemed better to break it before the Guile
828 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
829 Their prototypes were already present in gc.h, but they weren't
831 (scm_init_storage): Initialize scm_protects.
832 * root.c (scm_protects): New element of scm_sys_protects.
834 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
836 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
838 * libguile.h: Added #include "libguile/net_db.h".
840 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
841 30 change. That file is only meant for communication between the
842 configuration process and load.c. If code linked against libguile
843 wants to get at the paths mentioned in libpath.h, it can call
844 functions declared in load.h.
846 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
848 * libguile.h: Removed #include "libguile/fdsocket.h"
850 * net_db.c: Added #include <sys/socket.h>.
852 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
854 * filesys.c (scm_input_waiting_p): use select in preference to
855 FIONREAD, since the latter doesn't detect EOF.
856 Throw error if neither select nor FIONREAD available.
858 * socket.c (scm_connect): take a port, not a fd object.
859 (scm_fill_sockaddr): throw an error if fam is not recognised.
860 (scm_bind): use scm_fill_sockaddr.
861 (scm_listen): take a port, not a fd object.
862 (scm_accept): take and return a port. return #f in the car if
864 (scm_sock_fd_to_port): new procedure.
865 (scm_socket): use scm_sock_fd_to_port.
866 (scm_addr_vector): throw error if unrecognised address type.
867 take an extra argument with the calling procedure name.
868 (scm_getsockname): take a port. return #f if address can't be got.
869 (scm_getpeername): take a port. return #f if address can't be got.
870 (scm_recvfrom): take a port. return #f for address component if can't
872 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
873 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
875 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
877 * throw.c (scm_internal_catch): Make body funcs and handler funcs
878 use separate data pointers, to allow them to be designed
879 independently and reused.
880 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
881 Renamed from catch_body, catch_handler, and uncaught_throw; made
883 (struct scm_catch_body_data): Renamed from catch_body_data; moved
885 (scm_catch): Use the above.
886 (scm_throw): Don't bother printing a message for an uncaught
887 throw; we establish a default handler in init.
888 * throw.h (scm_internal_catch): Prototype updated.
889 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
891 (struct scm_body_thunk_data): New structure, used as data
892 argument to scm_body_thunk.
893 * init.c (struct main_func_closure): New structure, packaging up
894 the data to pass to the user's main function.
895 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
896 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
897 scm_internal_catch to establish a catch-all handler, using
898 scm_handle_by_message. This replaces the special-case code in
900 (invoke_main_func): Body function for scm_internal_catch; invoke
901 the user's main function, using the main_func_closure pointer to
902 decide what to pass it.
903 * root.c (struct cwdr_body_data): Remove handler_proc member.
904 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
905 (cwdr_handler): Removed.
907 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
909 * socket.h (SCM_P): update bind prototype.
910 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
912 (scm_socket): return a port, not a file descriptor object.
913 include "fports.h" and <unistd.h>
914 (scm_bind): take a port, not a file descriptor object.
915 take an extra argument for address args.
917 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
918 INADDR_NONE, INADDR_LOOPBACK.
920 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
922 * init.c: include net_db.h and not fdsocket.h.
923 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
925 * Makefile.am: corresponding changes.
926 * socket.h: renamed from fdsocket.h, fix names.
927 * net_db.h: renamed from socket.h, fix names.
928 * socket.c: renamed from fdsocket.c.
929 remove _sys from procedure names.
930 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
931 add "socket" to features list.
932 * net_db.c: renamed from socket.c.
933 remove _sys from procedure names.
934 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
935 add "net-db" to features list.
936 include "net_db.h". don't include <sys/socket.h> or
939 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
941 * tags.h (scm_tags): Removed comma at end of last enumerator.
943 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
945 Don't use GCC extensions to allocate space for debugging frames.
946 (Here he goes again! Why do we put up with this?!)
947 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
948 an scm_debug_info structure, not an in-line array of them. Add
949 'info' member, to say how many vect elements we've used, for eval
951 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
952 a new variable debug_info_end to mark the end of vect, instead of
953 the address of the 'info' pointer itself.
954 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
955 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
956 (SCM_APPLY): Explicitly allocate space for debug.vect.
957 * debug.c (scm_m_start_stack): Same, for vframe.vect.
958 * stacks.c: Adjusted for new debug frame structure.
959 (RELOC_INFO, RELOC_FRAME): New macros.
960 (stack_depth, read_frames): Use them, and new scm_debug_frame
961 element 'info', instead of magically knowing that eval frames have
962 an info pointer sitting after vect.
963 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
965 (scm_init_stacks): Formatting tweaks.
967 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
969 Give GCC more control flow information, so it can be sure that
970 variables aren't used uninitialized.
971 * error.h (scm_error, scm_syserror, scm_syserror_msg,
972 scm_sysmissing, scm_num_overflow, scm_out_of_range,
973 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
974 scm_misc_error): Tell GCC that these functions never return.
975 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
976 out the field type, call abort if SCM_ASSERT returns, to placate
978 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
979 scm_wta ever returns. We can't handle this case anyway, and this
980 gives the optimizer more information.
981 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
982 scm_wta ever returns.
984 In some cases, the code is fine, but GCC isn't smart enough to
985 figure that out; this usually happens when one variable is only
986 initialized and used when a particular condition holds true, and
987 we know that condition will never change within a given invocation
988 of the function. In this case, we simply initialize the variables
989 to placate the compiler, hopefully to a value which will cause a
990 crash if it is ever actually used.
991 * print.c (scm_iprin1): Initialize mw_pos.
992 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
993 * throw.c (scm_ithrow): Initialize dynpair.
994 * unif.c (scm_uniform_vector_ref): Initialize cra.
995 * struct.c (init_struct): Initialize prot.
996 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
998 * strports.c (scm_eval_0str): Don't return uninitialized garbage
999 if EXPR contains no expressions.
1001 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
1003 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
1004 cause an infinite loop (???). So much for the algebraic
1005 equivalency of variable-sized arrays and alloca...
1007 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
1009 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
1010 a SCM boolean, not a C boolean.
1012 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
1014 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
1015 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
1016 rules for raising scm_mtrigger. Previously, unfortunate but not
1017 unlikely circumstances could result in almost constant invokation
1018 of the gc. Now, this situations should be less likely, but they
1019 are not prevented completely.
1021 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
1023 * numbers.c (scm_fuck): Procedure removed; looks like old test
1025 * numbers.h: Prototype removed.
1027 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
1029 * debug.h (scm_debug_frame): Change `vect' member from an in-line
1030 array to a pointer, to match my Nov 21 change in eval.c.
1032 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1034 * libguile.h: Added #include "libguile/backtrace.h", #include
1035 "libguile/stacks.h".
1037 * strings.c (scm_string scm_make_string scm_string_ref
1038 scm_string_set_x scm_string_equal_p scm_string_append):
1039 Bugfix according to scm patch from Aubrey Jaffer:
1040 Corrected long-standing
1041 (not (eqv? (integer->char 128)
1042 (string-ref (make-string 1 (integer->char 128)) 0)))
1043 bug found by John Kozak <jk@noontide.demon.co.uk>.
1045 * strports.c, strports.h: Make scm_eval_0str return the value of
1046 the last expression evaluated (previously, it returned void).
1048 * strports.c, strports.h: New function: scm_read_0str. Does what
1051 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1053 * simpos.c (scm_getenv): return #f if string can't be found in the
1054 environment instead of throwing an exception, for compatibility
1055 with numerous other systems.
1057 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
1059 * Makefile.am (.c.x): Use guile-snarf.
1060 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
1062 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
1064 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1066 * backtrace.c (scm_display_error_message): Made non-static, and
1067 renamed from display_error_message.
1068 * backtrace.h (scm_display_error_message): Added extern decl.
1069 * throw.c (uncaught_throw): Use it to display the error message.
1071 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
1073 * inet_aton.c: Use #if 0, not #ifdef 0.
1075 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
1077 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
1078 to convert the returned value.
1079 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
1080 the offset argument.
1082 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1084 Add new interface to catch/throw, usable from C as well as
1086 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
1087 (scm_internal_catch): New function, replaces...
1088 (scm_catch_apply): Deleted.
1089 * throw.c (scm_catch_apply): Deleted; replaced with a more general
1090 mechanism which is a bit more code, but can be used nicely from C
1091 and implement the Scheme semantics as well.
1092 (scm_internal_catch): This is the replacement; it's named after
1093 the analogous function in Emacs.
1094 (scm_catch): Reimplemented in terms of the above.
1095 (struct catch_body_data, catch_body, catch_handler): New
1096 functions, used by scm_catch.
1097 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
1098 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
1099 support for new cwdr.
1101 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
1104 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
1106 * acconfig.h: Added DYNAMIC_LINKING symbol.
1107 * configure.in: Add option and checks for dynamic linking.
1108 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
1109 dynl.h: New files for dynamic linking support.
1110 * Makefile.am (libguile_a_SOURCES):
1112 (modinclude_HEADERS): Added "dynl.h".
1113 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
1115 * init.c (scm_boot_guile_1): Call
1116 scm_init_dynamic_linking to initialize dynamic linking support.
1118 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
1120 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
1121 (as we Schemers say). It needs to be global, so that I can tweak
1122 it for the proper operation of unexec.
1123 (scm_boot_guile_1_live): New variable, see above.
1125 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
1127 * guile-snarf.sh: Removed.
1128 * PLUGIN/guile.libs: Added dependency for -lm.
1129 * acinclude.m4: Renamed from aclocal.m4.
1130 * PLUGIN/greet: Removed.
1131 * Makefile.am, aclocal.m4: New files.
1132 * configure.in: Updated for Automake.
1134 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
1136 * eval.c (scm_definedp): Use top_level_lookup_closure_var
1137 and not top_level_lookup_thunk_var.
1139 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
1141 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
1143 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
1145 * eval.c (scm_definedp): Incompatibly changed to be a builtin
1146 Scheme function, instead of syntax. Single argument is now a
1149 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1151 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
1152 scm_ra_divide): Properly terminate statements passed as arguments
1153 to IVDEP macros. (Thanks to Bernard Urban.)
1155 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
1156 with non-constant sizes. (Thanks to Bernard Urban.)
1158 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1160 It's an "eval closure", not an "eval thunk." A thunk is a
1161 function of no arguments.
1162 * root.h (struct scm_root_state): Renamed
1163 top_level_lookup_closure_var from top_level_lookup_thunk_var.
1164 (scm_top_level_lookup_closure_var): Renamed from
1165 scm_top_level_lookup_thunk_var.
1166 * root.c (mark_root): Uses changed.
1167 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
1168 * init.c (scm_start_stack): Uses changed.
1169 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
1170 Change scheme-visible name to *top-level-lookup-closure* from
1171 *top-level-lookup-thunk*.
1173 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
1175 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
1176 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
1178 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
1180 * gc.c (struct scm_heap_seg_data): Doc fixes.
1182 * gc.c (scm_gc_sweep): Empty all segments' freelists before
1183 sweeping. Then, prepend each segment's free cells to its
1184 freelist, rather than wiping out the old value. (Thanks to Marius
1187 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
1188 scm_check_freelist, scm_debug_newcell): New functions and
1189 variables, for debugging freelist problems.
1190 * pairs.h (SCM_NEWCELL): New debugging version added.
1191 * gc.h (scm_debug_newcell): Added extern declaration, used by
1192 debugging version of SCM_NEWCELL.
1194 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1196 On some systems <libc.h> conflicts with <unistd.h>, and should not
1197 be #included at all.
1198 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
1199 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
1200 * configure.in: Call it.
1201 * posix.c, filesys.c: Use its results to decide whether or not to
1203 * configure, scmconfig.h.in: Rebuilt with autoconf and
1206 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1208 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
1209 pointer to the stdio stream before calling scm_setbuf0, so the
1210 latter will be able to retrieve it. I'm surprised this didn't
1211 segfault earlier. (Thanks to Christopher Lee.)
1213 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1215 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
1218 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1220 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
1221 number of stack narrowing specifier pairs. The first specifier in
1222 a pair controls inner border, the second the outer border. A
1223 number means cut that number of frames, a procedure object means
1224 cut until that object is found in operator position in a frame.
1226 * root.c (cwdr): Bugfix.
1228 * read.c: Recording of positions disabled by default.
1230 * procs.c (scm_closure_p): New function.
1232 * posix.c (scm_tmpnam): New function.
1234 * load.c: Added #include "throw.h".
1235 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
1238 * load.c, load.h (scm_read_and_eval_x): New function.
1240 * eval.c: Renamed debug option "deval" to "debug".
1242 (scm_eval_x): `eval!' is no longer accessible from the scheme
1243 level. Motivation: We can't allow operations which introduce
1244 glocs into the scheme level. Guile's type system can't handle
1245 these as data. Use `eval' or `read-and-eval!' as replacement.
1247 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
1248 SCM_CONSP since this is a macro!; Set vframe.prev to
1249 scm_last_debug_frame instead of 0. In this way we can look
1250 "above" the virtual start stack frame if we wish.
1251 (scm_debug_hang): New function: Useful for debugging Guile in
1252 certain tricky situations. Will probably be removed later...
1254 * debug.h: Changed semantics of debug option "backtrace". This
1255 option now only indicates whether we want automatic backtrace at
1258 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1260 * ports.c: #include "filesys.h"
1261 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
1263 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
1264 Motivation: This is system specific code which is related to file
1265 I/O. It also may use select. Added code by Gary Houston to
1266 detect presence of character in stdio buffers.
1268 * libguile.h: #include "libguile/libpath.h"
1270 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
1271 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
1272 SCM_SITE_DIR; Install libpath.h among the other include files.
1274 * load.c, load.h (scm_sys_package_data_dir): New function.
1276 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1278 * stacks.h: Bugfix: Don't use tail-array length field as stack
1279 length field! This screwed GC.
1281 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1283 * _scm.h: Added #ifndef around definition of macros min and max.
1285 * __scm.h: Added hooks for threads to plugin to in ints protection
1286 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
1287 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
1288 the main code in these macros duplicated and spread over multiple
1289 files. Renamed SCM_THREADS_SWITCHING_CODE ->
1290 SCM_THREAD_SWITCHING_CODE.
1292 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
1294 * snarf.h: New file.
1295 * guile-snarf.sh: New file.
1296 * Makefile.in (inner_h_files): Added snarf.h
1297 (ancillary, install, uninstall, distclean): Added actions for
1299 (.c.x): Use guile-snarf.
1300 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
1301 (gen_c_files): Note that these depend on guile-snarf.
1302 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
1303 now in "snarf.h". Added #include "snarf.h" to get them.
1304 * libguile.h: Added #include "snarf.h".
1305 (Patches applied and tweaked by Jim Blandy.)
1307 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1309 * socket.c: Use K&R style declaration for 'close'; the GNU coding
1310 standards suggest against providing prototypes for system
1311 functions. Thanks to Greg Troxel.
1313 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1315 * strports.c (scm_eval_0str): New function.
1316 #include "read.h", to get prototype for scm_read.
1317 * Makefile.in (strports.o): Update dependencies.
1318 * strports.h: New prototype.
1320 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
1321 scheme name from "int?" to "integer?". It seems to do the job.
1322 * numbers.h: Rename prototype too.
1323 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
1326 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
1327 scm_num_eq_p): Rename these according to R4RS conventions: call
1328 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
1329 to making libguile R4RS compliant without ice-9...
1331 * load.c (scm_sys_search_load_path): Search for files under all
1332 extensions listed in the %load-extensions variable. If FILENAME
1333 is absolute, return it unchanged, without searching the load path.
1334 (scm_loc_load_extensions): New variable, pointing to
1335 %load-extensions' value cell.
1336 (scm_init_load): Initialize it, and the value it points to.
1337 (scm_primitive_load_path): Improve error reporting.
1339 * load.c (scm_loc_load_hook): New variable, pointing to value cell
1340 of new Scheme variable %load-hook.
1341 (scm_primitive_load): Apply %load-hook to filename.
1343 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
1345 * configure.in: add tests for figuring out whether buffered data
1346 is available in a FILE structure, which is needed by char-ready.
1348 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
1351 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
1352 exceptions using misc_error instead of syserror. It seems a bit
1353 odd to throw an exception if a string can't be found in the
1354 environment, but it's consistent with open-file, stat etc.
1355 (simpos.h): remove sys_ from getenv.
1357 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
1358 occurs, throw an error instead of returning errno. Return value
1360 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1362 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1364 * filesys.c (scm_stat2scm): derive file type and permissions from
1365 the stat mode and append them to the returned vector.
1366 There isn't much overhead in doing this and it avoids the need to
1367 work with S_IRUSR et al. in Scheme.
1368 Define symbols scm_sym_regular etc.
1369 (scm_init_filesys): don't intern S_IRUSR etc.
1371 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1372 and s_primitive_load_path.
1374 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1376 * error.h: don't declare error symbols. prototype for scm_misc_error.
1378 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1381 * error.c: use SCM_SYMBOL to set up error keys.
1382 scm_misc_error: new procedure.
1384 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1386 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1387 between `#!' and `!#' is ignored.
1388 (skip_scsh_block_comment): New function.
1390 * feature.c (scm_set_program_arguments): New argument, FIRST.
1391 * feature.h: Update prototype.
1392 * init.c (scm_boot_guile_1): Pass new argument to
1393 scm_set_program_arguments.
1395 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1397 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1398 (scm_boot_guile): Call scm_set_program_arguments here, later than
1399 the old initialization.
1401 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1402 initialization procedure.
1403 - Delete in, out, err arguments; there are other perfectly good
1404 ways to override these when desired.
1405 - Delete result argument; this function shouldn't ever return.
1406 - Rename init_func argument to main_func, for less confusion.
1407 - Delete boot_cmd argument; main_func is more general.
1408 -Add 'closure' argument, to help people pass data to main_func
1409 without resorting to global variables.
1410 - Abort if reentered; don't bother returning an error code.
1411 - Call scm_init_standard_ports to set up the default/current
1412 standard ports; no need to pass them to scm_start_stack.
1413 - Remove code to evaluate the boot_cmd, and start the repl; let
1414 the user do something like that in main_func if they want.
1415 - Remove code to package up a return value; main_func can do any
1417 - Call exit (0), instead of returning.
1418 (scm_start_stack): Don't initialize the I/O ports here; that's
1419 weird. Delete in, out, err arguments. Move guts to
1420 scm_init_standard_ports, scm_stdio_to_port.
1421 (scm_init_standard_ports): New function, to set up current and
1422 default standard ports.
1423 (scm_start_stack, scm_restart_stack): Make these static.
1424 * init.h (scm_boot_guile): Adjust declaration.
1425 (scm_start_stack, scm_restart_stack): Remove externally
1426 visible declarations for these.
1427 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1429 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1430 written out several times in scm_start_stack.
1431 * fports.h: New declaration for the above.
1433 * feature.c (scm_set_program_arguments): New function.
1434 * feature.h: New declaration for the above.
1436 * ports.c: Formatting tweak.
1438 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1440 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1441 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1442 for obtaining the address of a car or cdr field. Motivation:
1443 &SCM_CXR make assumptions about the internal structure of the
1446 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1447 Motivation: see SCM_CXRLOC.
1449 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1450 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1451 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1452 Motivation: Safer use. Some other macros are defined in terms of
1453 these operations. If these are defined using the SCM_SETCXR
1454 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1455 to inefficiency and an <e1> with side-effects could potentially
1456 break. Also, these particular operations are heavily utilized in
1457 the garbage collector. In unoptimized code there will be a
1460 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1461 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
1462 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
1463 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
1464 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
1465 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1466 vports.c: Cleaned up use of pairs: Don't make any special
1467 assumptions about the internal structure of selectors and
1468 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1469 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1470 (Among other things, this change makes it easier to build Guile
1471 with certain compilers which have problems with casted lvalues.)
1473 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1475 * stacks.c: Improve selection of relevant stack frames when making
1476 a stack object. Introduce one level of indirection in the stack
1477 object to make it possible to "narrow" to a certain region of the
1478 stack. This facilitates making use of more clever algorithms (not
1479 implemented) for selecting relevant frames and gives a cleaner
1480 design since selection of frames can be done independently of
1481 extraction of frames from the real stack.
1482 (scm_stack_id): Also take #t as argument which means look at
1485 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1486 Turn n_tail into an integer directly representing current number
1487 of frames in stack. Add field tail.
1489 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1491 * debug.c (scm_make_memoized): Made it available at scheme level.
1492 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1493 SCM_NIMP before applying heavier predicates in argument checking.
1494 (scm_local_eval): Also take memoized object as argument.
1496 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1497 aren't created with zero length, but should such a strange
1498 creature suddenly turn up...
1500 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1502 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1503 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1505 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1507 * variable.c (scm_make_variable): Make the name hint optional, as
1509 (anonymous_variable_sym): Renamed from variable_sym. All uses
1512 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1513 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1514 of scm_primitive_load_path was also changed to
1515 "primitive-load-path", from "%try-load-path". Callers changed.
1516 We'd like to respect the convention that a function named
1517 "try-mumble" should behave just like the function called "mumble",
1518 but return #f instead of signalling some error.
1519 * load.h: Rename prototypes.
1521 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1523 * print.c (make_print_state, grow_print_state), print.h: Modified
1524 the print state representation: Don't use a tail array for
1525 recording of circular references. Resizing of the print state
1526 structure invalidates the print state pointer. To avoid passing
1527 around an indirect print state reference to all printing
1528 functions, we instead let the print state reference a resizable
1531 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1533 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1534 Don't crash when passed an improper list terminated by a
1535 non-immediate value.
1537 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1539 Allocate data for structures on an eight-byte boundary, as
1540 required by the tagging system.
1541 * struct.c (alloc_struct): New function.
1542 (scm_make_struct, scm_make_vtable_vtable): Call it.
1543 * struct.h (scm_struct_n_extra_words): Bump to 3.
1544 (scm_struct_i_ptr): New "field".
1545 * gc.c (scm_gc_sweep): When we need to free the data, use the
1546 information stored by alloc_struct to find the beginning of the
1547 block allocated to the structure, so we can free it.
1549 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1551 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1554 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1555 (scm_debug_info): New member: id.
1557 * stacks.c: Stacks are now represented as structs; Stacks have an
1558 id given to them by `start-stack'.
1559 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1561 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1562 Changed stack representation.
1564 * debug.c (scm_procedure_name): Try procedure property `name' for
1565 compiled closures aswell.
1567 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
1569 * eval.c: scm_i_name moved to gsubr.c
1570 (scm_m_define): Record names of all kinds of procedure
1571 objects. (Earlier, only closures were recorded.)
1573 * procprop.h: Added declaration of scm_i_name.
1575 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1576 (scm_make_gsubr): Record names of compiled closures.
1578 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1580 * debug.c, debug.h: Removed obsolete code.
1582 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1583 stacks.c: Renamed regs --> scm_contregs.
1585 * print.c (scm_free_print_state): Cleanup print state before
1586 returning it to pool. It is better to do it here than in
1587 scm_prin1 since scm_prin1 is called often.
1589 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1590 s_set_source_property_x): Check that first argument is a pair or a
1593 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1594 scm_i_line, scm_i_column and scm_i_breakpoint global.
1596 * init.c: Added #include "backtrace.h" and #include "stacks.h".
1597 (scm_boot_guile_1): Added calls to scm_init_backtrace and
1600 * debug.h: Added debug object smob declaration and macro
1603 * configure.in: Build with backtrace.o and stacks.o if debug
1606 * Makefile.in: Added entries for new files: backtrace.c,
1607 backtrace.h, stacks.c and stacks.h.
1609 * symbols.c (scm_sym2ovcell): Fixed documentation.
1611 * _scm.h (min, max): Added.
1613 * async.c: Moved `min' macro to _scm.h.
1615 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1616 SCM_BACKTRACE_INDENT.
1618 * eval.c: Added new debug options `maxdepth' and `indent'.
1620 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
1622 * print.h: Added selector SCM_PRINT_STATE.
1624 * print.c: New functions: scm_make_print_state,
1625 scm_free_print_state.
1627 * print.h: Added declarations for scm_make_print_state,
1628 scm_free_print_state.
1630 * debug.c (scm_m_start_stack): New acro.
1632 * debug.h: Small cleanup.
1634 * init.c (scm_boot_guile_1): Moved scm_init_debug below
1637 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

1657 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
1658 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
1659 declare functions with prototypes. (Patch thanks to Marius
1662 More prototype-related changes from Marius Vollmer:
1663 * gdb_interface.h: Wrapped header file in #ifdef/#endif
1664 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
1665 * ports.h (ptobfuns): Added prototypes. This means some casting in
1667 * fports.c: Added casts for initializations, since the functions
1668 are defined to take FILE * as their stream argument, not SCM.
1669 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
1670 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
1671 to `char *str_data' to conform to prototype.
1673 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1675 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
1677 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
1679 * stime.c, stime.h: use SCM_P method.
1681 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1683 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
1684 be given at least two arguments. Insist that lst's last element
1685 be a list, but don't make any requirements of its predecessors.
1687 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1689 * eval.c (scm_nconc2last): Revert last change; there seems to be
1690 other stuff going on here.
1692 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1694 * eval.c (scm_nconc2last): Make sure that each element of lst
1695 (which is a list of argument lists, except for the tail) is a
1696 proper list, i.e., finite and terminated by '().
1698 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1700 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
1703 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
1704 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
1707 * vectors.c (scm_make_vector): Fill vectors with the undefined
1708 value, to help make Guile Scheme code more portable to other
1711 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
1712 * symbols.h, tags.h: Doc fixes.
1714 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
1716 * async.c (scm_take_signal): Doc fixes.
1718 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
1720 * numbers.c (scm_divbigint): When the remainder is zero, we don't
1721 want to subtract it from the modulus; we just want to leave it
1724 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
1726 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
1729 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
1731 * throw.c (scm_catch_apply): Finished implementation of
1734 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
1736 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
1738 (scm_init_filesys): set "i/o-extensions" feature.
1741 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
1743 * Makefile.in (root.o): Correct dependencies.
1745 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
1747 * Makefile.in: Added dependency entry for root.o.
1749 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
1750 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
1752 * init.c (scm_start_stack): Set initial root continuation number
1755 * procs.c: New function: scm_thunk_p.
1757 * procs.h: Added declarations of scm_thunk_p.
1759 * root.c: Renamed `call-with-new-root' -->
1760 `call-with-dynamic-root'.
1761 (cwdr): Removed allocation of new root state. This should be done
1762 separately by use of scm_make_root.
1763 (scm_apply_with_dynamic_root): New function: Does what it
1764 sounds like. Needed when spawning threads.
1766 * root.h: Added member last_debug_frame to root state.
1767 Added #include "libguile/debug.h"
1769 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
1770 arguments. The motivation is that code in root.c needs catch
1771 functionality, and we want to avoid code duplication.
1772 New functions: scm_catch, scm_lazy_catch. These are wrappers for
1773 scm_catch_apply. scm_lazy_catch is intended to introduce catch
1774 handlers that run without popping the stack into the dynwind
1777 * throw.h: Added prototypes for scm_catch_apply and
1780 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1782 * root.h (scm_root, scm_set_root): Decouple thread support details
1783 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
1784 SCM_SET_THREAD_LOCAL_DATA.
1786 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
1787 and tortoise scanning loop.
1789 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
1791 * Makefile.in: Rebuild dependencies.
1793 * libguile.h: #include "libguile/print.h" before "smob.h", since
1794 the latter uses the print_state structure.
1796 * throw.c (scm_ithrow): Use the correct variable when checking to
1797 see if a given element of scm_dynwinds is a valid catch.
1799 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
1800 structure, abort; don't just silently ignore the garbage.
1802 * _scm.h: #include "print.h" here, since it seems to be used just
1804 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
1805 strports.c, unif.h: Don't #include "print.h".
1807 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1809 * feature.h (scm_loc_features): Removed external declaration.
1810 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
1812 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1814 * feature.c (scm_init_feature): Added threads feature (needs to be
1815 initialized here, since features doesn't exist when
1816 scm_init_threads is called).
1818 * libguile.h: Added #include "libguile/../threads/threads.h".
1819 (This is a kludge to get thread support working. This should be
1822 * configure.in, acconfig.h: Added flags for thread support.
1824 * scmsigs.c: Define `signal' to be `pthread_signal' if using
1827 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
1828 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
1831 * _scm.h: Added conditional #include "threads.h"
1833 * __scm.h (SCM_ASYNC_TICK): Added call to macro
1834 SCM_THREADS_SWITCHING_CODE.
1836 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
1837 allocate the basic dynamic root object.
1838 (scm_boot_guile): Added call to scm_init_root.
1840 * root.c, root.h: Added root smob.
1841 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
1842 functions: Implements dynamic roots mostly according to spec in
1843 SCM manual. Main difference is that the second argument is a
1844 throw handler rather than an error "thunk".
1846 * root.h: Added declaration of scm_init_root.
1848 * root.c: Added #include "genio.h", #include "smob.h", #include
1849 "pairs.h", #include "throw.h", #include "dynwind.h", #include
1851 (scm_init_root): Added #include "root.x".
1853 * throw.c: Added #include "stackchk.h"
1854 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
1855 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
1856 can be used in scm_call_with_new_root; Added reenabling of stack
1857 checking when catching a throw.
1859 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
1861 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
1863 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
1864 element is not found, as per R4RS.
1866 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1868 * list.c: Doc fixes throughout.
1870 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1872 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
1873 declare the char * to be const. Avoids a warning in rgx.c.
1875 * ports.h: spelling fix.
1877 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
1880 * load.c (scm_sys_try_load_path): throw an error if file not found
1881 (like it says it in NEWS).
1883 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1885 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
1886 PROPS slot to '(), not #f; it's an empty alist.
1888 * throw.h, throw.c: Use SCM_P instead of #if hair.
1890 Remove special support for uncaught throws; see throw.c for
1892 * throw.c (uncaught_throw): New function.
1893 (scm_ithrow): Call uncaught_throw if we don't find a throw
1894 target; don't mess with scm_bad_throw_vcell.
1895 (scm_bad_throw_vcell): Variable deleted.
1896 (scm_init_throw): Don't initialize it.
1898 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
1901 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1903 * numbers.c (scm_istr2int): If the number is short (as most
1904 numbers are), just call scm_small_istr2int to deal with it.
1905 (scm_small_istr2int): New function, created by un-#ifdefing the
1906 non-bignum version of scm_istr2int and renaming it.
1908 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
1910 * load.c (scm_sys_try_load): don't check whether value returned
1911 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
1912 Change the Scheme name from %try-load to primitive-load.
1914 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
1915 Can avoid passing a message, allowing it to be derived in the
1916 error handler (e.g., if we want to throw to the key both from
1919 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
1921 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
1922 references now have a new appearance which is more compact and
1923 also gives a clue about what the target of the reference is.
1924 By setting parameters in the print state, more fancy printing can
1925 be achieved. This is used by the (not yet commited) backtrace
1928 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
1930 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
1933 * print.c: Added #include "struct.h". Removed function
1936 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
1937 scm_iprin1. Removed prototype for scm_prlist.
1939 * arbiters.c (prinarb),
1940 async.c (print_async),
1941 debug.c (prindebugobj, prinmemoized),
1942 eval.c (prinprom, prinmacro),
1943 filesys.c (scm_fd_print, scm_dir_print),
1945 mallocs.c (prinmalloc),
1946 numbers.c, numbers.h (scm_floprint, scm_bigprint),
1947 smob.h (scm_smobfuns),
1948 srcprop.c (prinsrcprops),
1950 unif.c, unif.h (scm_raprin1, rapr1),
1951 variable.c (prin_var): Changed argument `int writing' to
1952 `scm_print_state *pstate'.
1954 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
1955 that it will be called before scm_init_print.
1957 * print.c (scm_prin1): Print states are now allocated when calling
1958 scm_prin1 and then passed around to all printing functions as an
1959 argument. A cache `print_state_pool' enables reuse of print
1961 (scm_make_print_state): New function.
1962 (scm_iprin1): Adaption to print states.
1963 (scm_iprlist): An initial "hare and tortoise" scan brings down
1964 time complexity to O (depth * N). (Better time complexity will be
1965 achieved when the printing code is completely rewritten.)
1967 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1969 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
1970 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
1971 it gets done whether or not the cache variable has a value.
1973 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
1975 Distinguish #f and ().
1976 * __scm.h: #undef SICP.
1977 * pairs.h (SCM_EOL): Delete this definition, equating it with
1979 * tags.h (SCM_EOL): Give it a new definition here; I think I found
1980 the value it used to have. Doc fixes, too.
1982 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
1984 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
1985 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
1986 Lord's implementation of structs, allowing for tail arrays as
1987 described in the manual. Also fixed some bugs. (Both the interface
1988 and the implementation should be improved.)
1990 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
1992 * print.c, print.h: Closures now print like #<procedure foo (x)>.
1993 People who whish to see the source can do `(print-enable 'source)'.
1994 Removed #ifdef DEBUG_EXTENSIONS.
1996 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1998 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
1999 integer (assuming for now accepting an integer is a good thing).
2001 * error.c, fports.c: replace use of %S in lgh_error args with %s.
2002 %S will be used instead for write'ing arguments.
2004 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
2005 asserts. fix a few other asserts.
2006 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
2007 scm_uniform_vector_ref, scm_array_set_x,
2008 scm_dimensions_to_unform_array): change args in
2009 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
2010 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
2011 scm_substring_fill_x): likewise.
2012 gsubr.c (scm_gsubr_apply): likewise.
2013 eval.c (SCM_APPLY): likewise.
2015 * eval.c (4 places): replace scm_everr with lgh_error or
2018 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
2019 scm_memory_error): new procedures.
2020 scm_everr: deleted. can use scm_wta, dropping first two args.
2021 scm_error: convert NULL subr to SCM_BOOL_F.
2023 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
2026 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
2029 * error.c, error.h: new error keys: scm_arg_type_key,
2030 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
2032 scm_wta: reimplement using lgh_error instead of scm_everr.
2034 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
2036 * gdbint.c: scm_lread now has one more argument.
2038 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
2039 scm_port_\1; Added mutator scm_set_port_filename_x (used when
2040 loading source from non-file ports, which, e. g., happens when
2041 using the Emacs interface).
2043 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
2046 * read.c: Added code for recording of positions of source code
2047 expressions; New functions: recsexpr, scm_lreadrecparen;
2048 _scm_make_srcprops --> scm_make_srcprops
2049 (scm_flush_ws): Removed updating of positions counters. This work
2050 is already done by scm_gen_getc
2052 * read.h: Added prototype for scm_lreadrecparen
2054 * print.c: Added #include "alist.h"
2056 * eval.c: Added #include "hash.h"
2058 * eq.c: Added #include "ramap.h"
2060 * options.c: Documentation fixes.
2062 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
2063 (scm_init_srcprop): Adjusted size of initial source-whash. Name
2064 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
2065 --> scm_make_srcprops
2067 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
2068 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
2069 function calls in the definition of the whash access macros.
2071 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
2073 * init.c (scm_boot_guile): Add level of indirection to
2074 scm_boot_guile_1() to ensure that stack base pointer is properly
2075 initialized. There was no guarantee that variable i was the
2076 highest/lowest variable on stack (i.e. the call frame of
2077 scm_boot_guile was not completely protected from gc).
2079 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
2081 * ports.h (scm_port_table): put back file_name, it will be used to
2082 support debugging. Undo related changes in fports.c, ioext.c,
2085 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2087 * ports.h (scm_port_table): remove file_name member for now, it seems
2089 * fports.c (scm_open_file): don't set file_name in PTAB.
2090 (prinfport): don't use file_name in PTAB.
2091 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
2092 * ports.c (scm_add_to_port_table): don't intialize file_name.
2093 (scm_port_file_name): remove for now.
2094 * gc.c (scm_gc_mark): don't mark PTAB file_name.
2096 * fports.h (scm_mkfile): prototype deleted.
2097 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
2099 * debug.c, unif.c: use scm_out_of_range instead of
2100 wta for range errors (ASSERT still needs work).
2102 * error.c, error.h (scm_out_of_range): new procedure.
2104 * error.c, error.h (scm_out_of_range_key): new key.
2106 * posix.c (scm_sync): #else was missing.
2108 * error.c, error.h: append _key to names scm_num_overflow and
2111 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
2112 of consing an empty list.
2113 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
2114 of macros, saves code and string space.
2115 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
2116 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
2117 lower case. Rename scm_syserror_m to scm_syserror_msg.
2118 error.h: prototypes for new procedures.
2120 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
2122 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
2124 * error.c, error.h: setup scm_num_overflow key.
2126 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
2127 Remove definition of SCM_OVSCM_FLOW.
2129 * fports.c (scm_open_file): use SCM_SYSERROR_M.
2131 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
2132 explicit message and args.
2134 * error.c, error.h, __scm.h: change system_error_sym to
2137 * error.c (system_error_sym): remove leading %% from the Scheme name
2140 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
2142 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2144 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
2145 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
2146 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
2147 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
2148 renamed. (These were introduced by unsupervised name
2151 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2153 * print.c: Added code for detection of circular references during
2154 printing. (init_ref_stack, grow_ref_stack): New functions. Added
2155 a hook for printing of closures (accessible via print options).
2156 This leads to a split of calls to scm_iprin1 into two classes:
2157 elementary print operations (e. g. the code which prints a smob)
2158 still use scm_iprin1 while top level calls (like scm_display) use
2159 scm_prin1. scm_prin1 begins by clearing the data structure used
2160 to record reference information.
2162 * print.h: Added declarations of scm_prin1 and scm_prlist.
2164 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
2166 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
2168 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
2170 * error.c (err_head): scm_iprin1 --> scm_prin1
2172 * debug.c: Adjusted header comment.
2176 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2178 * strerror.c: Doc fix.
2180 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2182 * gdbint.c (gdb_read): Now possible to run during GC.
2183 (unmark_port, remark_port): New functions.
2185 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
2187 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
2188 of allocating a new string object. Also, increase size by
2189 the factor 2 instead of 1.5.
2191 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
2193 * __scm.h (SCM_P): Corrected to run under traditional C.
2195 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
2198 * async.c: Calls to scm_sysintern corrected.
2200 * async.h (scm_async_clock): Redundant declaration removed.
2202 * continuations.c (scm_dynthrow): Redundant declaration removed.
2204 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
2205 Definition typos corrected.
2207 * debug.h: Missing declarations of functions in debug.c added
2210 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2211 Missing declarations to functions in eval.c added.
2213 * filesys.c: Possibly uninitialized variable rv.
2215 * gc.h (scm_object_addr, scm_unhash_name): Missing
2216 declarations of functions defined in gc.c added.
2218 * genio.c: Possible typos str_data -> wstr_data. ???
2220 * genio.c: Possibly unintended shadowing of local variable
2221 `int c' (gotos out of scope of inner `c'). ???
2223 * init.c: Uninitialized `SCM last' may be used.
2225 * ioext.h: (scm_sys_isatty_p): Typo.
2227 * list.h (scm_list_head): Missing prototype for function in
2230 * numbers.c (scm_two_doubles): Changed from extern to static
2231 (is used only within numbers.c).
2233 * numbers.h: Repeated declarations removed.
2235 * ports.h (scm_close_all_ports_except): Declaration for the
2236 function defined in ports.c added.
2238 * posix.h: Missing declarations added.
2240 * procs.h (scm_make_subr_opt): Missing declaration added.
2242 * socket.h (scm_sys_gethost): Missing declaration added.
2244 * socket.h: Redundant declarations removed (they are in fdsocket.h).
2246 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
2247 Missing declarations added.
2249 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
2251 * struct.c: Uninitialized variable `SCM answer' may be used.
2253 * unif.c (l2ra): Declaration prototype.
2255 * unif.c (scm_array_equal_p): Dummy definition removed (it is
2256 defined in ramap.c).
2258 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
2259 Redundant declarations removed (they are in ramap.h).
2261 * variable.h (scm_make_udvariable,
2262 scm_make_undefined_variable): Declaration corrected to
2263 correspond variable.c.
2265 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
2266 Missing declarations added.
2268 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
2270 * Makefile.in (distclean): Don't forget to delete fd.h.
2272 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2274 * fd.h.in, tags.h: Trivial cleanups.
2276 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
2277 marksweep.h just declared functions from gc.c.
2278 * gc.h, libguile.h: Don't #include "marksweep.h".
2279 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2280 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
2281 dependencies updated.
2283 * libguile.h: Don't #include "files.h"; it's been deleted.
2285 * files.c (scm_sys_delete_file): Moved to filesys.c.
2286 File is now empty; deleted.
2288 * filesys.c: scm_sys_delete_file is now here. Remove
2289 #if's; they seem to rely on remnants of an old portability
2290 regimen. If the problems come up again, solve them properly,
2291 using autoconf. Specifically: Don't test M_SYSV, and #define
2292 remove to be unlink if it's #defined; don't use remove just
2293 because HAVE_STDC_HEADERS is #defined.
2294 * filesys.h: Add declarations for scm_sys_delete_file.
2295 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2296 files.o, files.h, files.c, and files.x.
2297 * init.c: Don't #include "files.h", and don't call scm_init_files.
2299 Use SCM_P instead of PROTO; the latter intrudes on the user's
2301 * params.h: Deleted; definition of SCM_P moved to...
2302 * __scm.h: ... here, where it replaces PROTO macro.
2303 * libguile.h, smob.h: Don't #include "params.h".
2304 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
2305 smob.h: Fix prototypes accordingly.
2306 * Makefile.in: Update dependencies.
2307 (inner_h_files): Remove params.h.
2309 * gc.c: #include "gc.h"; every module should include its header,
2310 to let the compiler cross-check the declarations against the
2313 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2314 simpos.h: #include "libguile/__scm.h".
2316 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2318 * init.c: Don't forget to #include smob.h and init.h.
2319 * Makefile.in: Dependencies updated.
2321 * smob.h: Use PROTO instead of #if __STDC__.
2323 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2325 * __scm.h: Doc fixes.
2327 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2328 <angles>; this allows `make depends' to work properly.
2330 * libguile.h: #include smob.h and pairs.h before the others; they
2331 define typedefs used by other headers.
2333 C files should #include only the header files they need, not
2334 libguile.h (which #includes all the header files); the pointless
2335 recompilation was wasting my time.
2336 * Makefile.in (all .o dependency lists): Regenerated.
2337 * libguile.h: Don't try to get a definition for size_t here...
2338 * __scm.h: Do it here.
2339 * _scm.h: Since this is the internal libguile header, put things
2340 here that all (or a majority) of the libguile files will want.
2341 Don't #include <libguile.h> here; that generates dependencies on
2342 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2343 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2344 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

2421 * srcprop.c: Get "srcprop.h", "weaks.h", "hashtab.h", "debug.h",
2422 "alist.h", "smob.h".
2423 * stackchk.c: Get "stackchk.h", "genio.h".
2424 * stime.c: Get "stime.h"."libguile/continuations.h".
2425 * strings.c: Get "strings.h", "chars.h".
2426 * strop.c: Get "strop.h", "chars.h".
2427 * strorder.c: Get "strorder.h", "chars.h".
2428 * strports.c: Get "strports.h", "print.h", "eval.h", "unif.h".
2429 * struct.c: Get "struct.h", "chars.h".
2430 * symbols.c: Get "symbols.h", "mbstrings.h", "alist.h",

2433 * throw.c: Get "throw.h", "continuations.h", "debug.h",
2434 "dynwind.h", "eval.h", "alist.h", "smob.h", "genio.h".
2435 * unif.c: Get "unif.h", "feature.h", "strop.h", "sequences.h",
2436 "smob.h", "genio.h", "eval.h", "chars.h".
2437 * variable.c: Get "variable.h", "smob.h", "genio.h".
2438 * vectors.c: Get "vectors.h", "eq.h".

2440 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
2441 * weaks.c: Get "weaks.h".
2443 * stackchk.h: #include "libguile/debug.h",
2445 * print.h, read.h: #include "options.h", since everyone who uses
2446 either of these files will need that.
2448 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2449 anyone who uses this file will need them to define the smob
2450 printing functions. Also, get markers.h, since people will need
2451 to #define the mark functions.
2453 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2454 * ports.h: ... to here.
2456 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2457 don't rely on archaic C default type rules.
2459 * fports.h: #include "libguile/ports.h", since you need that in
2460 order to parse this.
2462 * genio.h: #include "libguile/print.h", because you need that to
2463 parse this; don't bother #including "ports.h", since print.h gets
2466 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2468 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2469 this; it's now a reference to an element of *scm_root.
2471 * debug.h: Don't #include "options.h"; the compiler won't be able
2472 to find that once the headers are installed; instead, #include
2473 "libguile/options.h".
2474 * gc.h: Same, with marksweep.h.
2475 * mbstrings.h: Same, with symbols.h.
2476 * scmhob.h: Same, with _scm.h.
2477 * smob.h: Same, with params.h.
2479 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2480 C files; there's no need for this, and it forces recompilations
2483 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2485 * error.c (scm_error): declare scm_error_callback.
2487 * error.h: prototype for scm_error_callback.
2489 * __scm.h: define lgh_error.
2490 (SCM_SYSERROR): redefine using lgh_error.
2492 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2494 * error.c (scm_error): new procedure.
2496 * error.h: prototype for scm_error.
2498 * Makefile.in (install): install scmconfig.h from the current
2499 directory, not $(srcdir).
2501 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2503 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2504 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2505 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
2506 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
2507 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
2508 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2509 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2510 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2511 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2512 vports.h, weaks.h: #include "libguile/__scm.h", not
2513 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2514 dependencies are within libguile properly.
2516 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2518 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2519 when scmconfig.h doesn't exist.
2521 * load.c (scm_sys_try_load): Correct spelling.
2523 * feature.c (scm_loc_features): Make this static.
2525 * Makefile.in (libpath.h): Omit trailing slash from path. We
2526 shouldn't require it of users, so why put it here?
2528 Move code to initialize and search %load-path from ice-9 to C
2529 code, so we can use the load-path to find the ice-9 boot code;
2530 this makes it easier to run Guile without installing it. See
2531 corresponding changes in guile/Makefile.in.
2532 * feature.c: Move stuff concerned with the load path to load.c.
2533 (scm_compiled_library_path): Deleted.
2534 Don't #include libpath.h here.
2535 * feature.h: Don't mention scm_compiled_library_path.
2536 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2537 <sys/stat.h>, and <unistd.h> (if present).
2538 (R_OK): #define if the system hasn't deigned to.
2539 (scm_loc_load_path): New variable.
2540 (scm_init_load_path, scm_sys_search_load_path,
2541 scm_sys_try_load_path): New functions.
2542 (scm_init_load): Initialize scm_loc_load_path to point to the
2543 value cell of the Scheme %load-path variable.
2544 * load.h: Add declarations for scm_sys_search_load_path,
2545 scm_sys_try_load_path.
2546 * init.c: Call scm_init_load_path.
2547 * Makefile.in (feature.o, load.o): Dependencies updated.
2549 * load.c, load.h: Rewrite using PROTO macro.
2551 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2553 * gc.c (scm_cellp): New function: C predicate to determine if an
2554 SCM value can be regarded as a pointer to a cell on the heap.
2556 * gc.h: Added declaration of scm_cellp.
2558 * gdb_interface.h: New file: The GDB interface header from the GDB
2561 * gdbint.c: New file: GDB interface.
2563 * gdbint.h: New file: GDB interface.
2565 * libguile.h: Added #include <libguile/gdbint.h>.
2567 * init.c (scm_boot_guile): Added scm_init_gdbint.
2569 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2570 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2571 found if object files and source are kept separate).
2573 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2575 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2577 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2579 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2580 TK_SRC_DIR; they're not relevant any more.
2582 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2583 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2585 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2587 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2588 search path, so we can find the <libguile/MUMBLE.h> headers.
2590 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2592 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2593 implicit in the .c.o rule.
2594 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2597 Put the library path in a header file, instead of passing it on
2598 the command line in every compilation.
2599 * Makefile.in (libpath.h): New target.
2600 (feature.o): Depend on libpath.h.
2601 (clean): Delete libpath.h.
2602 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2603 * feature.c: ... #include "libpath.h" here.
2604 * .cvsignore: Ignore libpath.h.
2606 Don't install the unwashed masses of Guile header files in the
2607 main #include path; put most of them in a subdirectory called
2608 'libguile'. This avoids naming conflicts between Guile header
2609 files and system header files (of which there were a few).
2610 * Makefile.in (pkgincludedir): Deleted.
2611 (innerincludedir): New variable; this and $(includedir) are enough.
2612 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
2613 (installed_h_files): Divide this up. Now this variable lists
2614 those header files which should go into $(includedir) (i.e. appear
2615 directly in the #include path), and ...
2616 (inner_h_files): ... this new variable says which files appear in
2617 a subdirectory, and are referred to as <libguile/mumble.h>.
2618 (h_files): List them both.
2619 (install): Create innerincludedir, not pkgincludedir. Put
2620 the installed_h_files and inner_h_files in their proper places.
2621 (uninstall): Corresponding changes.
2622 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2623 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2624 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
2625 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
2626 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
2627 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2628 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2629 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2630 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2631 vports.h, weaks.h: Find __scm.h in its new location.
2632 * __scm.h: Find scmconfig.h and tags.h in their new locations
2633 (they're both "inner" files).
2635 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
2637 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
2639 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2641 * posix.c: Doc fixes.
2643 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
2645 * socket.c: Don't include a prototype for inet_aton; just use a
2646 K&R style declaration, to avoid warnings but minimize the chance
2647 of conflicts with the system.
2649 On NextStep, <utime.h> doesn't define struct utime, unless we
2650 #define _POSIX_SOURCE before #including it.
2651 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
2652 * acconfig.h: New comment text for above CPP symbol.
2653 * configure.in: Call it.
2654 * posix.c: #define _POSIX_SOURCE if it seems necessary.
2656 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
2658 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
2659 testing for __EMX__.
2661 * posix.c: #include <libc.h>, if it exists.
2663 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
2664 don't even know if the latter exists.
2666 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
2667 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
2668 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
2670 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
2672 (scm_init_posix): Use them when initializing the Scheme constants
2675 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2677 * Makefile.in (libdir, includedir, bindir): Use the
2678 autoconf-supplied values, instead of deriving them ourselves.
2679 (pkgincludedir, datadir, pkgdatadir): New variables.
2680 (install, uninstall): Put the header files in a special
2681 subdirectory, not in the main search path.
2683 * Makefile.in (ALL_CFLAGS): Provide the proper value for
2684 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
2686 * Makefile.in (IMPLPATH): Deleted; never used.
2688 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
2689 on the Tcl/Tk source any more.
2690 (INCLUDE_CFLAGS): Remove references to the above.
2692 * Makefile.in (version.o): Corrected dependencies.
2694 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
2696 * libguile.h: #include "version.h"
2698 * init.c (scm_boot_guile): Call scm_init_version.
2699 * gscm.c (gscm_run_scm): Call scm_init_version.
2701 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
2702 GUILE_VERSION): AC_DEFINE these.
2703 (acconfig.h): #undef the above symbols.
2705 * Makefile.in (libobjs): Add version.o.
2706 (installed_h_files): Add version.h.
2707 (c_files): Add version.c.
2708 (gen_c_files): Add version.x.
2709 (version.o): New rule.
2710 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
2711 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

2719 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
2720 weaks.o): Add version.h to dependency lists.
2721 (markers.o): Remove duplicate rule.
2723 * version.h: New file.
2725 * version.c: New file.
2727 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2729 * symbols.c (scm_strhash): scm_downcase is now a function, not an
2730 array; use it appropriately. Since GCC is quite happy to
2731 subscript functions, it never warned us about this; we should use
2732 -Wpointer-arith in the future. I guess we never tested
2735 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2737 * socket.c: Doc and copyright fixes.
2739 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2741 * debug.c: Fixed and improved gdb support.
2743 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2745 * socket.c: Added declaration of inet_aton to avoid compiler
2746 warning. (Hope this solution is correct.)
2748 * stime.c: Added declaration of ftime. (This is missing in
2751 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
2753 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2755 * Makefile.in (c_files): add strerror.c.
2757 * strerror.c: new file from Emacs' sysdep.c.
2758 maybe configure should also check for sys_errlist.
2760 * configure.in (AC_REPLACE_FUNCS): add strerror.
2762 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2764 * debug.c (scm_init_debug): Added initialization for
2765 scm_evaluator_traps.
2767 * debug.h, debug.c: Various name changes.
2768 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
2769 "debug-options-interface". See commentary in options.c.
2771 * options.h, options.c: Options now have documentation strings.
2772 Also added a long explanatory commentary.
2774 * eval.c, print.h, print.c, read.h, read.c: Modifications to
2777 * gscm.c, init.c, root.c, throw.c: Bug fixes:
2778 last_debug_info_frame is now updated in all cases.
2780 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
2783 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2785 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
2786 Added option STACK_CHECKING.
2788 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
2790 * Makefile.in: Added {debug,options,srcprop}.{h,c}
2792 * __scm.h: Removed symbols for debugging support.
2794 * acconfig.h: Added symbols for debugging support.
2796 * configure.in: Added user option for debugging support.
2797 --enable-debug will include the debugging code into libguile.a.
2799 * continuations.c (scm_make_cont): Enlarged the #if 0 around
2800 scm_relocate_chunk_to_heap.
2802 * debug.c: New file: low-level debugging support. It also
2803 includes support for debugging with gdb. (The extensions to gdb
2804 are written by Per Bothner at Cygnus.)
2806 * debug.h: New file: low-level debugging support.
2808 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
2809 argument pairs. Extensive modifications to the debugging
2810 evaluator. Added "SECTION:" commentaries to clarify what happens
2811 when, during double compilation. Renamed EVALIMP --> EVALIM.
2812 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
2813 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
2814 the beginning of the file. New procedure: scm_unmemocopy.
2815 Added some global state variables needed by the debugging
2816 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
2817 check_entry, check_apply, check_exit, debug_options and
2818 evaluator_traps. New acro: undefine.
2820 * eval.h: Renamed EVAL --> XEVAL.
2822 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
2823 --> scm_make_weak_key_hash_table.
2825 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
2826 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
2828 * libguile.h: Conditionally include debug.h
2830 * objprop.c (scm_object_properties, scm_set_object_properties_x):
2831 scm_object_properties shouldn't return handle. `handle' now gets
2832 initialized in scm_set_object_properties_x. scm_object_properties
2833 doesn't any longer create an entry in scm_object_whash.
2835 * options.c: New file: handling of run time options.
2837 * options.h: New file: handling of run time options.
2839 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
2841 * print.c: New procedure: scm_print_options
2843 * print.h: Defines for print options.
2845 * read.c: New procedure: scm_read_options
2847 * read.h: Defines for reader options.
2849 * root.h: Added scm_source_whash among scm_sys_protects.
2851 * srcprop.c: New file: source properties.
2853 * srcprop.h: New file: source properties.
2855 * throw.c (jbsmob): Jump buffers are now correctly allocated.
2856 (Bug found by A. Green.)
2858 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2860 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2862 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
2864 * libguile.h: #include "objprop.h"; I guess this was forgotten.
2866 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
2867 and should be called by the final client.
2869 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
2871 * gc.h: Use the PROTO macro when declaring functions.
2872 * gc.c: Use the PROTO macro when declaring static functions.
2873 Remove the CPP hair around function definitions.
2875 * gc.c (scm_init_storage): Initialize scm_asyncs.
2877 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
2878 preprocessor symbol; "__scm.h" is where it might get #defined.
2879 * __scm.h: Similar: #include <scmconfig.h> before testing
2882 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
2884 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
2886 * init.c (scm_boot_guile): Add init_func argument; call
2887 (*init_func) instead of calling scm_appinit; it's ucky to
2888 hard-code names for the user's procedures.
2889 * init.h (scm_boot_guile): Adjust declaration.
2891 * __scm.h (PROTO): New macro, for declaring functions with
2894 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
2895 eliminate all the __STDC__ conditionals.
2896 (scm_boot_guile): Add declaration.
2897 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
2898 Remove __STDC__ conditionals around function definitions; the
2899 declarations in init.h will provide the same information, more
2902 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
2903 complain about it in the error message; the error message is
2904 adequate without that note, and there's nothing the user can do
2907 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
2909 * Makefile.in (ancillary): Drop def.sed.
2911 * posix.c (scm_init_posix): Use numeric values, rather than
2912 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
2913 F_OK. The symbols aren't available on some systems, and I'm
2914 pretty sure their values are fixed by common widespread practice.
2915 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
2917 More functions unavailable on some systems.
2918 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
2919 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
2921 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2922 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
2923 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
2924 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
2925 stub that signals an error as the #else.
2927 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
2929 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
2931 * Fixes motivated by Petr Adamek <adamek@mit.edu>:

2951 * posix.c: fewer ttyname declarations.
2953 * fports.c: include <string.h> not "string.h".

2960 genio.c, simpos.c, vports.c: include string.h.
2962 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
2964 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
2966 (scm_addr_buffer_size): change type from scm_sizet to int.
2967 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
2968 from scm_sizet to int.
2970 * error.c: include unistd.h.
2972 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
2975 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
2977 * __scm.hd, def.sed: deleted.
2979 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
2981 Changes for NeXT, suggested by Robert Brown.
2982 * configure.in: Call AC_TYPE_MODE_T.
2983 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
2984 NeXT. Put header file list in alphabetical order.
2985 * configure, scmconfig.h.in: Regenerated.
2986 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
2988 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
2991 * acconfig.h: New file, providing documentation for the CPP
2992 symbols defined in configure.in
2993 * acconfig-1.5.h: Removed; superceded by the above.
2995 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
2997 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
2999 * fports.c (scm_open_file): don't return #f, throw error.
3001 * ioext.c (fileno): renamed from %fileno.

3008 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
3010 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
3012 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
3014 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
3016 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3018 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
3019 This is necessary on Ultrix, and doesn't hurt portability.
3021 * Makefile.in (dist-dir): New target, implementing a new dist system.
3022 (installed_h_files): Put in alphabetical order.
3023 Remove duplicate entries for markers.h and unif.h.
3024 (c_files): Remove duplicate entries for markers.c.
3025 (ancillary): Renamed from anillery; all uses changed. Remove
3026 PLUGIN; it's a directory, and needs special treatment in dist-dir.
3027 Remove all the ../doc/* files; doc/Makefile.in handles that.
3029 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
3031 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
3032 every if must have an else, or else the whole command has a
3033 non-zero exit code whenever the if's condition is false.
3035 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
3037 * posix.c: include string.h.
3039 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
3041 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
3044 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
3045 Remove leading % from scheme names.
3046 Do not return error values, call SCM_SYSERROR or similar.
3048 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
3050 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
3052 * struct.c (scm_init_struct): new file.
3054 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
3056 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
3057 (scm_list_head): added list-head for rapidly chopping argument
3058 lists off of longer lists (and similar).

3063 handle for obj, not the handle itself.
3065 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
3067 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
3068 weak hash tables last of all marking to avoid an obscure gc bug.
3069 WARNING: circular lists stored in a weak hash table will hose us.
3071 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
3073 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):

3088 * strports.c (scm_strprint_obj): convenience function. C for
3089 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))

3095 Initialization specific to tcl interpreters removed.
3097 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
3099 * ports.c (scm_ports_prehistory): size malloced here doesn't
3100 matter so long as it is non-0 (got rid of "* 4").
3102 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
3104 * gscm.h: gscm_mkarray eliminated (presumably was not being used
3105 since its definition was bogus).
3107 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
3109 * mallocs.[ch]: back again (for rx at least).
3111 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
3113 * ports.c: removed functions relating to the mapping between ports
3114 and descriptors. (That stuff is unix-specific and should be collected
3115 in a separate library).
3117 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
3118 (Tom Mckay@avanticorp.com)
3120 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
3122 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
3123 handled correctly (SCM_FREEP was applied to them) -- test for
3124 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
3125 being overwritten with #f. (brown@grettir.bibliotech.com)

3169 (possibly triggering gc) before setting the tag of the corresponding
3172 * pairs.c (scm_delq_x): never throw an error.
3174 * vectors.c (scm_make_vector): made the default vector fill argument
3175 into '() (much more useful than the previous value, "#unspecified")

3179 * ports.c (scm_add_to_port_table): Added fields
3180 to port table entries: file_name, line_num, col.
3181 Update these in open_file, gen_getc and gen_ungetc.
3182 Added procedures to access those fields.
3184 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
3186 * procs.c (scm_make_subr_opt): new entry point for making

3219 This file is for stuff relating specifically to Scheme libraries
3222 * eval.c (scm_m_define): don't give warning about redefinition, don't
3225 NOTE: this should throw a resumable exception with parameters --
3226 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?

3250 because it changes size.
3252 (stputc stwrite): check/change the strings length with interrupts
3255 * objprop.c (scm_set_object_property_x &c): use the generic
3256 hashing functions and be threadsafe.

3259 (per suggestion jaffer@gnu.ai.mit.edu).
3261 * mbstrings.c (scm_multi_byte_string): guard against argument list
3264 * strings.c (scm_make_string): loop cleanup

3292 initialization to fix a race condition.
3294 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

3318 set the multi_byte flag correctly in symbols. This is wrong.
3319 intern_obbary_soft and msymbolize should take an extra parameter.
3320 Also, weird multibyte symbols don't print correctly.
3321 The weird symbol syntax is also a bit bogus (emacs doesn't quite
3324 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
3326 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
3327 use the system symhash. == #t means create an uninterned symbol.
3329 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
3331 * strings.c (scm_make_shared_substring): build'em.
3332 It might better to keep a table of these and use one

3419 Give a warning, not an error, for unrecognized modes.
