1 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
3 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
5 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
6 we're not using AM_INIT_GUILE_MODULE any more.
7 * Makefile.in: Reneregated.
9 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
11 Functions for finding variable bindings, grace à Tim Pierce.
12 * * gh_data.c (gh_lookup, gh_module_lookup): New functions.
13 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
15 Get 'make dist' to work again.
16 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
17 * Makefile.in: Regenerated, like a surry without a fringe on top.
19 Changes for reduced Guile distribution: one configure script,
21 * configure.in, configure: Removed.
22 * acconfig.h, acinclude.m4: Moved to parent directory, where the
23 real configure script lives.
24 * Makefile.in, scmconfig.h.in: Regenerated.
26 * init.c: #include "script.h", to get prototype for script.c's
29 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
31 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
32 scm_must_malloc, not raw malloc.
34 * script.c (scm_compile_shell_switches): Dyke out debugging output
37 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
39 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
41 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
42 system has them. Hope this is safe. Previously
43 sys/timeb.h was included if HAVE_FTIME was defined or if
44 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
45 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
47 * ioext.c (scm_setfileno): add missing third argument to
50 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
52 * eq.c (scm_equal_p): Correctly compare strings of different
53 varieties. (Thanks to Tim Pierce.)
55 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
57 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
58 #! block comment must occur on a line all by itself.
60 Move most of the guts of shell command processing into libguile,
61 so guile.c can be very small (and eventuallly auto-generated. (I
62 mean, generated mechanically, not self-generated. Hmm.))
63 * guile.c, script.c, script.h: New source files.
64 * init.c (scm_boot_guile_1): Call scm_init_script.
65 * libguile.h: #include "script.h".
66 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
67 targets, for new executable.
68 (libguile_la_SOURCES): Mention script.c.
69 (modinclude_HEADERS): Add script.h.
70 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
71 not dynamic linking is enabled. This is because we're generating
72 executables now. Move CY_AC_WITH_THREADS call after those, so the
73 values of cy_cv_threads_libs captures the libs chosen above.
74 * Makefile.in, configure, aclocal.m4: Regenerated.
76 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
77 We don't maintain this interface any more, and it just confuses
80 * alloca.c: #include <scmconfig.h>, not <config.h>.
81 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
82 it'll get included in disties.
84 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
86 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
87 be distributed, because they confuse people.
88 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
90 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
92 * configure.in: check for presence of gethostent (not present on
94 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
95 * configure, scmconfig.h.in: Regenerated.
97 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
99 * backtrace.c (scm_backtrace): Split message string across
100 newlines properly. GCC is more tolerant of this than other
103 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
105 Merge threads directory into libguile.
106 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,

112 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
113 coop-threads.c.cygnus, coop-threads.h.cygnus.
114 * configure.in: If we're using threads, include threads.o in
116 * _scm.h, libguile.h: threads.h lives in this directory now.
117 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
118 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
119 currently used, but brought along for information's sake.
120 * ChangeLog-threads: log from old 'threads' directory.
121 * Makefile.in, configure: Rebuilt.
123 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
125 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
128 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
130 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
132 Merge GH interface library into libguile.
133 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
134 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
135 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
136 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
138 (EXTRA_libguile_la_SOURCES): ... here.
139 (pkginclude_HEADERS): Add variable, to get gh.h installed.
140 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
141 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
142 New variables, describing how to build the gh test programs.
143 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
144 build the test programs, and we probably should have been linking
145 libguile.la against them all along, to support AIX shared libs.
146 Add cflags for threads to CFLAGS; add libs for threads to new
147 variable THREAD_LIBS, used in Makefile.am.
148 * ChangeLog-gh: log from old `gh' subdirectory.
149 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
151 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
153 * acconfig.h: Undo change of Apr 9; including the definition of
154 PACKAGE in the guile headers conflicts with applications' own
156 * scmconfig.h.in: Regenerated.
158 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

165 when PROC is receiving no arguments.
167 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
169 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
170 have S_IFSOCK. This is the case under Ultrix.
172 * posix.c (scm_status_exit_val, scm_status_exit_val,
173 scm_status_term_sig, scm_status_stop_sig): Modified to work with
174 Ultrix versions of WIFSTOPPED, etc., which assume that their
175 arguments are lvalues (hmm).
177 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
181 * throw.c: Doc fixes; rearranged.
183 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.

187 * acconfig.h: Added entry for PACKAGE.
188 * scmconfig.h.in: Regenerated.
190 Changes to work with automake-1.1n, which has better libtool support.
191 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
192 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
194 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
196 * Makefile.in: Rebuild.

205 (bdtime2c, setzone, restorezone): new static procedures.
206 (scm_mktime, scm_strftime): use them.
207 (scm_strftime): don't call mktime before strftime. Use
208 filltime for return value.
209 (filltime): convert NULL zname to #f.
210 * (scm_strptime): return a count of characters consumed, not
211 the remaining string.
213 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
215 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.

222 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
224 * stime.c (scm_init_stime): don't define ticks/sec.
225 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
226 return value problem and is still portable.)
228 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
230 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
231 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
232 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
233 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
234 cpp_err_symbols.c): Corresponding changes.
235 * Makefile.in: Regenerated.
237 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>

240 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
241 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
242 * putenv.c: new file, from sh-utils 1.12.
244 * posix.c (scm_environ): use malloc in place of scm_must_malloc
245 since allocation isn't for Scheme objects.
246 (scm_putenv): copy strings before placing in the environment.
248 * stime.c (scm_current_time): throw an error if time returns -1,
249 instead of returning #f.
250 (scm_get_internal_real_time, scm_get_internal_real_time): use
251 scm_long2num for return value instead of SCM_MAKINUM.
253 * stime.h: prototypes updated.
255 * stime.c (scm_time_in_msec): apparently unused, deleted.

259 * configure.in: check for gettimeofday.
261 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
262 which may be more usefully portable than a gettimeofday interface.
264 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
266 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
268 * Makefile.in: Regenerated.
270 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>

279 * * posix.c (scm_mknod): split the mode argument into type and perms
280 arguments, like the extra fields returned by stat.
282 * fports.c (scm_pipob): set the close, free and print procedures.
283 (scm_close_pipe): new procedure.
285 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,

288 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
290 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
291 wan't defined. Don't include fd.h.
293 * Previously fd.h was regenerated whenever configure was run,
294 forcing a couple of files to be recompiled.
296 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
297 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
298 Check for _fileno as well as _file.
300 * ioext.c: don't fd.h.
301 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
304 * Change the stratigy for getting information about errno
305 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
306 generating lists of symbols during the build process, which will
307 not always work, include comprehensive lists in the distribution.
308 To help keep the lists up to date, the "check_signals" and
309 "check_errnos" make targets can be used.
311 * configure.in: don't check for a command to extract errno codes.
312 * Makefile.am: update file lists, remove errnos.list and errnos.c
313 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
314 check_errnos targets.
315 (CLEANFILES): remove errnos.c and errnos.list, add
316 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new

323 * error.c (scm_init_error): #include cpp_err_symbols instead of
325 * posix.c (scm_init_posix): don't intern signal symbols. #include
328 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
330 * strop.c (scm_i_index): allow the lower bound to be equal to the
331 length of the string, so a null string doesn't always give an error.
333 * posix.h: new prototypes.
334 * posix.c (scm_status_exit_val, scm_status_term_sig,
335 scm_status_stop_sig): new functions, as in scsh. They break down
336 process status values as returned by waitpid.
338 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
340 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
341 configure doesn't know about it.
343 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
345 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
347 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
348 which defines C variables with global linkage.
350 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
352 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
355 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
357 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
358 has time to check why this doesn't work well with continuations.
360 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
362 * Fix shell syntax error; some shells won't tolerate
363 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
365 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
367 * posix.c (scm_uname): throw an error if uname fails instead
370 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
372 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
375 * async.c (scm_ints_disabled): definition moved from error.c.

379 * acconfig.h: Removed PACKAGE.
381 * scmconfig.h.in: Regenerated.
383 * snarf.h: g++ says it's non-portable not to specify the first
384 argument in a varargs declaration. I introduced the first
385 argument by using preprocessor conditionals.
387 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
389 * ioext.c (scm_read_delimited_x): use RO string macros for delims.

419 * error.h: prototype for scm_error_scm.
421 * error.c (scm_error_scm): new procedure, reimplements scm-error
422 in C and uses scm_error.
424 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
426 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
427 pointer to the Scheme variable read-hash-procedures and intern it
428 in scm_init_read. Modify scm_read_hash_extend and
429 scm_get_hash_procedure to use the pointer.
431 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
433 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
434 (SCM_KEYWORD_STYLE): defined.
436 * read.c (scm_read_opts): add a keywords option. This isn't a
437 boolean option, in case someone wants to add support for DSSSL
439 Setup scm_keyword_prefix symbol.
440 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
442 * I've left keyword support disabled by default, since it doesn't
443 seem to break the module system and it gives R4RS standard behaviour.
444 It can be reactivated with (read-set! keywords 'prefix).
446 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
448 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS

460 * read.c (scm_init_read): intitialise scm_read_hash_procedures
461 (idea from Mikael: make it a pair so scm_permanent object only
463 (scm_read_hash_extend): don't call scm_permanent_object.
464 (ideas from Mikael): if chr is already in the list, replace its
465 procedure instead of appending it again. If proc is #f, remove
467 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
469 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.

498 * read.c (scm_read_token): if case_i, downcase ic before doing
501 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
503 * configure.in: Added configuration option `guile-debug'.
504 Configure with --enable-guile-debug if you want a bunch of extra
505 functions used for debugging when developing Guile.
507 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
509 * procs.c (make-cclo): New undocumented debugging procedure: Make
510 compiled closure with internal procedure PROC and length LENGTH.
511 Only compiled if GUILE_DEBUG is defined.
513 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
515 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
517 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
519 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
520 with 3 or more args internally to the evaluator.
522 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
524 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
525 with 3 or more args internally to the evaluator. This is mainly
526 because we don't want to pass entry and exit points of the
527 debug support twice, but it also seems to increase the speed of
528 the evaluator for such calls (e. g. (+ 1 2 3)).
530 * * backtrace.c (scm_display_application): New procedure:
531 display-application; Set fancy printing parameters individually
532 for different types of display (backtrace, error, application).
533 (These should of course be customizable!)
535 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
536 clear the CHECK-flags.
538 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
540 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
542 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
544 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
545 from pairs with a GLOC in the car.
547 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
548 otherwise `symbol-hash' will behave badly.
549 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
550 we get segmentation fault!
552 * * symbols.c: Added #include "weaks.h". New functions:
553 `builtin-bindings' and `builtin-weak-bindings'. (These will be
554 moved to an extraneous library when we split libguile.)
556 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
558 * filesys.c (scm_stat): stat now takes fport arguments too as
559 documented in the manual.
561 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
563 * debug.c (scm_single_step): Bugfix: Call continuation with
564 scm_call_continuation instead of throwing to it.
566 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
568 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
569 argument wasn't declared to be optional.
571 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
573 * stime.c (scm_init_stime): Add feature "current-time".
575 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
577 * throw.h: prototype for scm_exit_status.
578 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
579 args to derive an exit status. Allows (quit) to work from a
581 (scm_exit_status): new function.
584 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
586 * eval.c (scm_deval): Removed some old code.
587 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
589 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
592 * symbols.c (msymbolize): Bugfix: Must initialize property list to
595 * procs.c: Introduce the existent C function scm_thunk_p at the
596 Scheme level as well.
598 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
600 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
601 used from C to easily lookup the value of a symbol in the current
604 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
606 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
607 scm_init_unif in this file. This will also fix a previous problem
610 * configure.in: Added AM_MAINTAINER_MODE
612 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
614 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
617 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
619 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
620 source files that are not always included in libguile but should
621 have their dependencies calculated by automake. This variable is
622 recognized by automake, no further magic is needed.
623 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
624 to deal exclusively with *.lo files, as it seems. The *.o files
625 are built automatically when the corresponding *.lo file gets
628 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
630 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
633 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
635 * unif.c (scm_array_set_x): minor change to argument error checking.
637 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
639 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
640 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
641 They should only be included in the library at configure.in's
643 (libguile_la_LDADD): Include the appropriate .lo files here.
644 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
645 so we know when to build them (and their .lo bretheren).
646 * configure.in (LIBLOBJS): New substituted variable. We let
647 configure decide which .o files to include in LIBOBJS, and then
648 put the corresponding list of .lo files in LIBLOBJS. The latter
649 is what we pass to libtool.
650 * Makefile.in, configure: regenerated.
652 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
654 * symbols.c (scm_sysintern0): New function. Contains the core of
655 old scm_sysintern but doesn't take a second value argument.
656 (scm_sysintern): Now uses scm_sysintern0.
657 (scm_sysintern_no_module_lookup): Renamed to
658 scm_sysintern0_no_module_lookup and doesn't take a second value
661 * symbols.h (scm_sysintern0: Added declaration.
663 * options.c (scm_init_opts): Use scm_sysintern0 instead of
664 scm_sysintern when interning option keys. Otherwise we risk
665 destroying the values of already interned variables.
667 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
668 scheme-level boolean (use SCM_NFALSEP).
670 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
672 (scm_backtrace): New function. (C version of old function from
673 boot-9.scm) Motivation: Make it possible to display backtraces
674 without depending on boot-9.scm. (I'm uncertain if this
675 motivation is good enough...)
677 * root.h (scm_root_state): Add member the_last_stack_var.
678 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
680 * root.c (mark_root): Mark scm_the_last_stack_var.
682 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
685 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
687 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
688 1. mark_lazy_catch didn't mark the smob.
689 2. Both functions above have standard variants:
690 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
691 free_lazy_catch --> scm_free0.
693 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
695 * throw.c (scm_internal_lazy_catch): New function.
696 (scm_lazy_catch): Rewritten to use it.
697 (scm_ithrow): Handle the new lazy catch representation.
698 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
699 that doesn't have a jmpbuf is a lazy catch clause.
700 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
701 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
702 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
704 (scm_init_throw): Register the new lazy-catch smob type.
705 * throw.h (scm_internal_lazy_catch): decl for new function.
707 * throw.c (scm_internal_catch): Doc fixes.
709 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
710 configure.in. Including this might cause problems if applications
711 that link against libguile include their own copies of alloca, but
712 if they're using autoconf, they should be adding libguile to LIBS
713 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
714 the copy in libguile, and things will be okay. (I think.)
716 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
718 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
720 strop.h: move prototypes too.
722 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
724 * posix.c (scm_init_posix): don't intern EINTR since it's now done
727 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
728 etc. I deleted them from filesys.c long ago, but didn't
729 notice they were here too (although ineffective since
730 sys/stat.h wasn't included).
732 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
734 * eval.c: Don't define alloca in GCC case. gcc will automatically
735 use __builtin_alloca if appropriate.
737 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
739 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
740 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
741 that values of automatic variables are preserved. See comments
742 for safe_setjmp for details.
744 Change from Thomas Morgan:
745 * variable.c: Include eq.h.
746 (var_equal): New function.
747 (variable_smob): Use var_equal as the discriminator for variables.
749 * throw.c (s_throw): Remove extraneous declaration.
751 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
752 * eval.c: Add necessary CPP cruft to support that.
753 * configure, Makefile.in, scmconfig.h.in: regenerated.
755 Change from Thomas Morgan:
756 * procprop.c (scm_procedure_properties): Convert the Scheme
757 boolean returned by scm_procedure_p into a C boolean before using
758 it as a condition for SCM_ASSERT.
759 (scm_procedure_property): Likewise.
761 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
762 indications of Unixness.
765 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
767 * * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
769 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
771 * read.c (scm_lreadr): use scm_misc_error to improve one of the
772 "unknown # object" error messages.
774 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
775 (scm_i_index) and declare it static. Add a 'direction' argument
776 to indicate what way the search should go.
777 (scm_i_index): throw out-of-range error instead of wrong-type-arg
779 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
780 strop.h: remove scm_i_index, scm_i_rindex prototypes.
782 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
784 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
786 * * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
787 to avoid clash with various scsh forks.
789 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
791 The following two changes (ramap.c, throw.c) are motivated by the
792 apparent unportability of forward declarations of static arrays of
793 the form `static foo bar[];'.
795 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
796 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
798 * throw.c (scm_throw): Moved above scm_ithrow.
800 * options.h: Removed the extern declarations of scm_yes_sym and
801 scm_no_sym since these are static.
803 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
805 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
807 * Makefile.am: remove AWK=@AWK@.
808 Add a rule for generating errnos.list.
809 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
811 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
812 don't extract errnos, just set a variable (avoids the
813 need to recompile error.c just because configure is run.)
815 * unif.h: update prototypes.
816 * unif.c (scm_uniform_array_read,write): change the offset and
817 length arguments to start and end, for consistency.
819 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
821 * ioext.h: update prototypes.
822 * * ioext.c (scm_read_delimited_x): replaces scm_read_line and
823 scm_read_line_x, it's a more general procedure using an
824 interface from scsh. read-line and read-line! are now defined
826 * Note that the new read-line trims the terminator
827 by default, previously it was appended to the returned string. An
828 optional argument specifies how to process the terminator (scsh
829 compatible). For the old behaviour: (read-line port 'concat).
830 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
831 returns a pair, but is converted to multiple values if the scsh
834 socket.h: update prototypes.
835 * socket.c (scm_recvfrom): for consistency with other procedures,
836 take start and end as separate optional arguments.
837 * (scm_recv, scm_recvfrom): don't allow the second argument
838 to be a size, only a buffer. Change the scheme names to
839 recv! and recvfrom!. Don't return the buffer.
841 * ioext.h, posix.h: move prototypes too.
842 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
843 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
844 "read.h" and "unif.h".
845 * ioext.c: include "chars.h"
847 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
849 * dynl.c: The dynamic linking and module registration functions
850 are now defined even when dynamic linking is not available for the
851 host system. Some of their functionality can be done without
852 dynamic linking; when it's really needed, they throw errors.
854 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
856 * configure.in: Only define DYNAMIC_LINKING when one of the system
857 dependent functions is detected.
858 * dynl.c (scm_dynamic_func): New function to get the address of a
859 function in a dynamic object.
860 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
861 produced by scm_dynamic_func as the thing to call.
863 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
865 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
866 (scm_register_module_xxx, scm_registered_modules,
867 scm_clear_registered_modules): New functions.
869 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
871 * symbols.c (scm_sysintern): Renamed to
872 scm_sysintern_no_module_lookup.
873 (scm_sysintern): New function to take the place of the old
874 scm_sysintern. It uses the current toplevel lookup closure to give
875 the symbol its value. This is a temporary hack to put packages
876 like gtcltk into their own module.
877 (scm_can_use_top_level_lookup_closure_var): New variable to tell
878 us whether `scm_top_level_lookup_closure_var' has been initialized
880 * eval.c (scm_init_eval): Set it.
882 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
884 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
885 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
887 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
889 * (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
890 scm_sys_dup): deleted: FD capability will be added to other
892 * Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
893 scm_fd_free, fd_smob, scm_intern_fd.
894 * (scm_open): renamed from scm_sys_open. Return a port instead of
895 an FD object. Make the mode argument optional.
896 * (scm_sys_create): deleted, it's just a special case of open.
897 (scm_init_filesys): move interning of constants O_CREAT etc.,
898 here (were previously using SCM_CONST_LONG macro).
899 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
901 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
902 include "fports.h" and <stdio.h>
903 (scm_stat, scm_select): don't support FD objects.
905 * error.h: adjust scm_syserror_msg prototype.
906 * error.c (scm_syserror_msg): take an extra argument for errno.
907 Using the global value didn't always work, since it could be
908 reset by procedure calls in the message or args arguments.
910 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
911 I don't understand why the check was there (and what about the
914 * strop.c (scm_string_copy): allow shared substrings to be copied.
916 * unif.h: corresponding change to prototypes.
917 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
918 recognize two new optional arguments: offset and length. Allow
919 the port argument to be an integer (file descriptor, for scsh).
920 Include <unistd.h> for "read" prototype.
922 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
924 * socket.c: don't include filesys.h.
926 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
928 * Makefile.am: add AWK=@AWK@ (?)
930 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
932 Add a rule to generate errnos.c from errnos.
933 * error.c (scm_init_error): include errnos.c.
934 * errnos_cnvt.awk: new file, converts the list of errno codes to
936 * errnos_get.c: new file.
937 * errnos.default: new file, contains errnos to try if they can't
938 be extracted from errno.h.
939 * configure.in: if using GCC, try and extract errno codes from
943 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
945 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
946 * Makefile.am: Made libguile into a libtool library.
947 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
948 Set libtool_libs to indicate that libguile is a libtool library.
949 See guile/ChangeLog for details.
950 * .cvsignore: ignore "*.lo", the libtool library objects.
952 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
954 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
955 use htons in getservbyport argument.
957 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
959 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
960 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
963 * objprop.c (scm_object_property): No need to take the CDR of the
964 value returned by scm_object_properties, since Aug 20 change.
966 * configure.in: When checking for struct linger, #include
967 <sys/types.h> as well as <sys/socket.h>. I've never known
968 <sys/types.h> to cause any portability problems, and Solaris's
969 <sys/socket.h> needs it.
970 * configure: Rebuilt.
972 I think the Sun compiler has chosen a perverse way to interpret
973 ANSI declarations combined with K&R definitions. We'll
974 appease it a little bit. But when it invades France, we fight.
975 * print.c (scm_iprlist): Change 'tlr' argument to an int.
976 * print.h (scm_iprlist): Here too.
977 * numbers.c (scm_divbigdig): Change definition to match
978 declaration in numbers.h.
979 * unif.c (scm_makflo): Change definition to match declaration in
982 * init.c (scm_boot_guile): Don't return the value of
983 scm_boot_guile_1. This function doesn't return a value;
984 scm_boot_guile_1 doesn't return a value (or return at all).
986 * eval.c (unmemocopy): Add a semicolon to appease the Sun
989 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
990 compile. I have a feeling this function is a bad idea anyway ---
991 one should always test for features, not systems.
993 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
994 semicolons. Only pure luck kept this from being noticed earlier.
996 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
998 * socket.c (scm_recvfrom): Added missing semicolon.
1000 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1002 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
1003 the buffer and start and end positions for scsh networking
1006 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
1008 * configure.in: Revert previous change to this file; the problem
1009 is due to transient automake weirdness.
1010 * configure: Rebuilt.
1012 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
1013 PLUGIN/guile.libs. configure generates the latter from the former.
1014 * Makefile.in: Rebuilt.
1016 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
1017 need this if we install scripts, like guile-snarf.
1018 * configure: Rebuilt.
1020 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1022 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
1024 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
1026 * socket.c (scm_addr_vector): fix faulty scm_listify.
1028 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
1030 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
1031 style block comment is no longer considered an error.
1033 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
1035 * PLUGIN/guile.libs.in: New file.
1036 * PLUGIN/guile.libs: Removed from repository.
1037 * configure.in: Create PLUGIN/guile.libs from
1038 PLUGIN/guile.libs.in. This is for including additonal libraries
1039 needed for dynamic linking.
1040 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
1041 instead of PLUGIN/guile.libs.
1043 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
1045 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
1047 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
1048 occurrences of the given element from the list, not just the
1049 first. This is how the Emacs Lisp functions behave, how the
1050 analogous Common Lisp functions behave, and (I believe) how the
1051 older Maclisp functions worked. I realize that this change may
1052 break code, but it seemed better to break it before the Guile
1055 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
1056 Their prototypes were already present in gc.h, but they weren't
1058 (scm_init_storage): Initialize scm_protects.
1059 * root.c (scm_protects): New element of scm_sys_protects.
1061 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
1063 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1065 * libguile.h: Added #include "libguile/net_db.h".
1067 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
1068 30 change. That file is only meant for communication between the
1069 configuration process and load.c. If code linked against libguile
1070 wants to get at the paths mentioned in libpath.h, it can call
1071 functions declared in load.h.
1073 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1075 * libguile.h: Removed #include "libguile/fdsocket.h"
1077 * net_db.c: Added #include <sys/socket.h>.
1079 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
1081 * filesys.c (scm_input_waiting_p): use select in preference to
1082 FIONREAD, since the latter doesn't detect EOF.
1083 Throw error if neither select nor FIONREAD available.
1085 * socket.c (scm_connect): take a port, not a fd object.
1086 (scm_fill_sockaddr): throw an error if fam is not recognised.
1087 (scm_bind): use scm_fill_sockaddr.
1088 (scm_listen): take a port, not a fd object.
1089 (scm_accept): take and return a port. return #f in the car if
1090 address can't be got
1091 (scm_sock_fd_to_port): new procedure.
1092 (scm_socket): use scm_sock_fd_to_port.
1093 (scm_addr_vector): throw error if unrecognised address type.
1094 take an extra argument with the calling procedure name.
1095 (scm_getsockname): take a port. return #f if address can't be got.
1096 (scm_getpeername): take a port. return #f if address can't be got.
1097 (scm_recvfrom): take a port. return #f for address component if can't
1099 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
1100 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
1102 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
1104 * throw.c (scm_internal_catch): Make body funcs and handler funcs
1105 use separate data pointers, to allow them to be designed
1106 independently and reused.
1107 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
1108 Renamed from catch_body, catch_handler, and uncaught_throw; made
1110 (struct scm_catch_body_data): Renamed from catch_body_data; moved
1112 (scm_catch): Use the above.
1113 (scm_throw): Don't bother printing a message for an uncaught
1114 throw; we establish a default handler in init.
1115 * throw.h (scm_internal_catch): Prototype updated.
1116 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
1118 (struct scm_body_thunk_data): New structure, used as data
1119 argument to scm_body_thunk.
1120 * init.c (struct main_func_closure): New structure, packaging up
1121 the data to pass to the user's main function.
1122 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
1123 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
1124 scm_internal_catch to establish a catch-all handler, using
1125 scm_handle_by_message. This replaces the special-case code in
1127 (invoke_main_func): Body function for scm_internal_catch; invoke
1128 the user's main function, using the main_func_closure pointer to
1129 decide what to pass it.
1130 * root.c (struct cwdr_body_data): Remove handler_proc member.
1131 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
1132 (cwdr_handler): Removed.
1134 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1136 * socket.h (SCM_P): update bind prototype.
1137 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
1138 include "feature.h".
1139 (scm_socket): return a port, not a file descriptor object.
1140 include "fports.h" and <unistd.h>
1141 (scm_bind): take a port, not a file descriptor object.
1142 take an extra argument for address args.
1144 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
1145 INADDR_NONE, INADDR_LOOPBACK.
1147 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1149 * init.c: include net_db.h and not fdsocket.h.
1150 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
1152 * Makefile.am: corresponding changes.
1153 * socket.h: renamed from fdsocket.h, fix names.
1154 * net_db.h: renamed from socket.h, fix names.
1155 * socket.c: renamed from fdsocket.c.
1156 remove _sys from procedure names.
1157 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
1158 add "socket" to features list.
1159 * net_db.c: renamed from socket.c.
1160 remove _sys from procedure names.
1161 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
1162 add "net-db" to features list.
1163 include "net_db.h". don't include <sys/socket.h> or
1166 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1168 * tags.h (scm_tags): Removed comma at end of last enumerator.
1170 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
1172 Don't use GCC extensions to allocate space for debugging frames.
1173 (Here he goes again! Why do we put up with this?!)
1174 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
1175 an scm_debug_info structure, not an in-line array of them. Add
1176 'info' member, to say how many vect elements we've used, for eval
1178 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
1179 a new variable debug_info_end to mark the end of vect, instead of
1180 the address of the 'info' pointer itself.
1181 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
1182 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
1183 (SCM_APPLY): Explicitly allocate space for debug.vect.
1184 * debug.c (scm_m_start_stack): Same, for vframe.vect.
1185 * stacks.c: Adjusted for new debug frame structure.
1186 (RELOC_INFO, RELOC_FRAME): New macros.
1187 (stack_depth, read_frames): Use them, and new scm_debug_frame
1188 element 'info', instead of magically knowing that eval frames have
1189 an info pointer sitting after vect.
1190 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
1192 (scm_init_stacks): Formatting tweaks.
1194 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
1196 Give GCC more control flow information, so it can be sure that
1197 variables aren't used uninitialized.
1198 * error.h (scm_error, scm_syserror, scm_syserror_msg,
1199 scm_sysmissing, scm_num_overflow, scm_out_of_range,
1200 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
1201 scm_misc_error): Tell GCC that these functions never return.
1202 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
1203 out the field type, call abort if SCM_ASSERT returns, to placate
1205 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
1206 scm_wta ever returns. We can't handle this case anyway, and this
1207 gives the optimizer more information.
1208 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
1209 scm_wta ever returns.
1211 In some cases, the code is fine, but GCC isn't smart enough to
1212 figure that out; this usually happens when one variable is only
1213 initialized and used when a particular condition holds true, and
1214 we know that condition will never change within a given invocation
1215 of the function. In this case, we simply initialize the variables
1216 to placate the compiler, hopefully to a value which will cause a
1217 crash if it is ever actually used.
1218 * print.c (scm_iprin1): Initialize mw_pos.
1219 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
1220 * throw.c (scm_ithrow): Initialize dynpair.
1221 * unif.c (scm_uniform_vector_ref): Initialize cra.
1222 * struct.c (init_struct): Initialize prot.
1223 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
1225 * strports.c (scm_eval_0str): Don't return uninitialized garbage
1226 if EXPR contains no expressions.
1228 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
1230 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
1231 cause an infinite loop (???). So much for the algebraic
1232 equivalency of variable-sized arrays and alloca...
1234 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
1236 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
1237 a SCM boolean, not a C boolean.
1239 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
1241 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
1242 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
1243 rules for raising scm_mtrigger. Previously, unfortunate but not
1244 unlikely circumstances could result in almost constant invokation
1245 of the gc. Now, this situations should be less likely, but they
1246 are not prevented completely.
1248 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
1250 * numbers.c (scm_fuck): Procedure removed; looks like old test
1252 * numbers.h: Prototype removed.
1254 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
1256 * debug.h (scm_debug_frame): Change `vect' member from an in-line
1257 array to a pointer, to match my Nov 21 change in eval.c.
1259 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1261 * libguile.h: Added #include "libguile/backtrace.h", #include
1262 "libguile/stacks.h".
1264 * strings.c (scm_string scm_make_string scm_string_ref
1265 scm_string_set_x scm_string_equal_p scm_string_append):
1266 Bugfix according to scm patch from Aubrey Jaffer:
1267 Corrected long-standing
1268 (not (eqv? (integer->char 128)
1269 (string-ref (make-string 1 (integer->char 128)) 0)))
1270 bug found by John Kozak <jk@noontide.demon.co.uk>.
1272 * strports.c, strports.h: Make scm_eval_0str return the value of
1273 the last expression evaluated (previously, it returned void).
1275 * strports.c, strports.h: New function: scm_read_0str. Does what
1278 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1280 * simpos.c (scm_getenv): return #f if string can't be found in the
1281 environment instead of throwing an exception, for compatibility
1282 with numerous other systems.
1284 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
1286 * Makefile.am (.c.x): Use guile-snarf.
1287 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
1289 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
1291 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1293 * backtrace.c (scm_display_error_message): Made non-static, and
1294 renamed from display_error_message.
1295 * backtrace.h (scm_display_error_message): Added extern decl.
1296 * throw.c (uncaught_throw): Use it to display the error message.
1298 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
1300 * inet_aton.c: Use #if 0, not #ifdef 0.
1302 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
1304 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
1305 to convert the returned value.
1306 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
1307 the offset argument.
1309 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1311 Add new interface to catch/throw, usable from C as well as
1313 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
1314 (scm_internal_catch): New function, replaces...
1315 (scm_catch_apply): Deleted.
1316 * throw.c (scm_catch_apply): Deleted; replaced with a more general
1317 mechanism which is a bit more code, but can be used nicely from C
1318 and implement the Scheme semantics as well.
1319 (scm_internal_catch): This is the replacement; it's named after
1320 the analogous function in Emacs.
1321 (scm_catch): Reimplemented in terms of the above.
1322 (struct catch_body_data, catch_body, catch_handler): New
1323 functions, used by scm_catch.
1324 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
1325 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
1326 support for new cwdr.
1328 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
1331 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
1333 * acconfig.h: Added DYNAMIC_LINKING symbol.
1334 * configure.in: Add option and checks for dynamic linking.
1335 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
1336 dynl.h: New files for dynamic linking support.
1337 * Makefile.am (libguile_a_SOURCES):
1339 (modinclude_HEADERS): Added "dynl.h".
1340 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
1342 * init.c (scm_boot_guile_1): Call
1343 scm_init_dynamic_linking to initialize dynamic linking support.
1345 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
1347 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
1348 (as we Schemers say). It needs to be global, so that I can tweak
1349 it for the proper operation of unexec.
1350 (scm_boot_guile_1_live): New variable, see above.
1352 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
1354 * guile-snarf.sh: Removed.
1355 * PLUGIN/guile.libs: Added dependency for -lm.
1356 * acinclude.m4: Renamed from aclocal.m4.
1357 * PLUGIN/greet: Removed.
1358 * Makefile.am, aclocal.m4: New files.
1359 * configure.in: Updated for Automake.
1361 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
1363 * eval.c (scm_definedp): Use top_level_lookup_closure_var
1364 and not top_level_lookup_thunk_var.
1366 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
1368 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
1370 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
1372 * eval.c (scm_definedp): Incompatibly changed to be a builtin
1373 Scheme function, instead of syntax. Single argument is now a
1376 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1378 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
1379 scm_ra_divide): Properly terminate statements passed as arguments
1380 to IVDEP macros. (Thanks to Bernard Urban.)
1382 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
1383 with non-constant sizes. (Thanks to Bernard Urban.)
1385 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1387 It's an "eval closure", not an "eval thunk." A thunk is a
1388 function of no arguments.
1389 * root.h (struct scm_root_state): Renamed
1390 top_level_lookup_closure_var from top_level_lookup_thunk_var.
1391 (scm_top_level_lookup_closure_var): Renamed from
1392 scm_top_level_lookup_thunk_var.
1393 * root.c (mark_root): Uses changed.
1394 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
1395 * init.c (scm_start_stack): Uses changed.
1396 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
1397 Change scheme-visible name to *top-level-lookup-closure* from
1398 *top-level-lookup-thunk*.
1400 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
1402 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
1403 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
1405 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
1407 * gc.c (struct scm_heap_seg_data): Doc fixes.
1409 * gc.c (scm_gc_sweep): Empty all segments' freelists before
1410 sweeping. Then, prepend each segment's free cells to its
1411 freelist, rather than wiping out the old value. (Thanks to Marius
1414 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
1415 scm_check_freelist, scm_debug_newcell): New functions and
1416 variables, for debugging freelist problems.
1417 * pairs.h (SCM_NEWCELL): New debugging version added.
1418 * gc.h (scm_debug_newcell): Added extern declaration, used by
1419 debugging version of SCM_NEWCELL.
1421 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1423 On some systems <libc.h> conflicts with <unistd.h>, and should not
1424 be #included at all.
1425 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
1426 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
1427 * configure.in: Call it.
1428 * posix.c, filesys.c: Use its results to decide whether or not to
1430 * configure, scmconfig.h.in: Rebuilt with autoconf and
1433 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1435 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
1436 pointer to the stdio stream before calling scm_setbuf0, so the
1437 latter will be able to retrieve it. I'm surprised this didn't
1438 segfault earlier. (Thanks to Christopher Lee.)
1440 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1442 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
1445 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1447 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
1448 number of stack narrowing specifier pairs. The first specifier in
1449 a pair controls inner border, the second the outer border. A
1450 number means cut that number of frames, a procedure object means
1451 cut until that object is found in operator position in a frame.
1453 * root.c (cwdr): Bugfix.
1455 * read.c: Recording of positions disabled by default.
1457 * procs.c (scm_closure_p): New function.
1459 * posix.c (scm_tmpnam): New function.
1461 * load.c: Added #include "throw.h".
1462 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
1465 * load.c, load.h (scm_read_and_eval_x): New function.
1467 * eval.c: Renamed debug option "deval" to "debug".
1469 (scm_eval_x): `eval!' is no longer accessible from the scheme
1470 level. Motivation: We can't allow operations which introduce
1471 glocs into the scheme level. Guile's type system can't handle
1472 these as data. Use `eval' or `read-and-eval!' as replacement.
1474 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
1475 SCM_CONSP since this is a macro!; Set vframe.prev to
1476 scm_last_debug_frame instead of 0. In this way we can look
1477 "above" the virtual start stack frame if we wish.
1478 (scm_debug_hang): New function: Useful for debugging Guile in
1479 certain tricky situations. Will probably be removed later...
1481 * debug.h: Changed semantics of debug option "backtrace". This
1482 option now only indicates whether we want automatic backtrace at
1485 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1487 * ports.c: #include "filesys.h"
1488 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
1490 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
1491 Motivation: This is system specific code which is related to file
1492 I/O. It also may use select. Added code by Gary Houston to
1493 detect presence of character in stdio buffers.
1495 * libguile.h: #include "libguile/libpath.h"
1497 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
1498 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
1499 SCM_SITE_DIR; Install libpath.h among the other include files.
1501 * load.c, load.h (scm_sys_package_data_dir): New function.
1503 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1505 * stacks.h: Bugfix: Don't use tail-array length field as stack
1506 length field! This screwed GC.
1508 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1510 * _scm.h: Added #ifndef around definition of macros min and max.
1512 * __scm.h: Added hooks for threads to plugin to in ints protection
1513 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
1514 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
1515 the main code in these macros duplicated and spread over multiple
1516 files. Renamed SCM_THREADS_SWITCHING_CODE ->
1517 SCM_THREAD_SWITCHING_CODE.
1519 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
1521 * snarf.h: New file.
1522 * guile-snarf.sh: New file.
1523 * Makefile.in (inner_h_files): Added snarf.h
1524 (ancillary, install, uninstall, distclean): Added actions for
1526 (.c.x): Use guile-snarf.
1527 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
1528 (gen_c_files): Note that these depend on guile-snarf.
1529 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
1530 now in "snarf.h". Added #include "snarf.h" to get them.
1531 * libguile.h: Added #include "snarf.h".
1532 (Patches applied and tweaked by Jim Blandy.)
1534 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1536 * socket.c: Use K&R style declaration for 'close'; the GNU coding
1537 standards suggest against providing prototypes for system
1538 functions. Thanks to Greg Troxel.
1540 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1542 * strports.c (scm_eval_0str): New function.
1543 #include "read.h", to get prototype for scm_read.
1544 * Makefile.in (strports.o): Update dependencies.
1545 * strports.h: New prototype.
1547 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
1548 scheme name from "int?" to "integer?". It seems to do the job.
1549 * numbers.h: Rename prototype too.
1550 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
1553 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
1554 scm_num_eq_p): Rename these according to R4RS conventions: call
1555 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
1556 to making libguile R4RS compliant without ice-9...
1558 * load.c (scm_sys_search_load_path): Search for files under all
1559 extensions listed in the %load-extensions variable. If FILENAME
1560 is absolute, return it unchanged, without searching the load path.
1561 (scm_loc_load_extensions): New variable, pointing to
1562 %load-extensions' value cell.
1563 (scm_init_load): Initialize it, and the value it points to.
1564 (scm_primitive_load_path): Improve error reporting.
1566 * load.c (scm_loc_load_hook): New variable, pointing to value cell
1567 of new Scheme variable %load-hook.
1568 (scm_primitive_load): Apply %load-hook to filename.
1570 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
1572 * configure.in: add tests for figuring out whether buffered data
1573 is available in a FILE structure, which is needed by char-ready.
1575 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
1578 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
1579 exceptions using misc_error instead of syserror. It seems a bit
1580 odd to throw an exception if a string can't be found in the
1581 environment, but it's consistent with open-file, stat etc.
1582 (simpos.h): remove sys_ from getenv.
1584 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
1585 occurs, throw an error instead of returning errno. Return value
1587 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1589 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1591 * filesys.c (scm_stat2scm): derive file type and permissions from
1592 the stat mode and append them to the returned vector.
1593 There isn't much overhead in doing this and it avoids the need to
1594 work with S_IRUSR et al. in Scheme.
1595 Define symbols scm_sym_regular etc.
1596 (scm_init_filesys): don't intern S_IRUSR etc.
1598 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1599 and s_primitive_load_path.
1601 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1603 * error.h: don't declare error symbols. prototype for scm_misc_error.
1605 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1608 * error.c: use SCM_SYMBOL to set up error keys.
1609 scm_misc_error: new procedure.
1611 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1613 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1614 between `#!' and `!#' is ignored.
1615 (skip_scsh_block_comment): New function.
1617 * feature.c (scm_set_program_arguments): New argument, FIRST.
1618 * feature.h: Update prototype.
1619 * init.c (scm_boot_guile_1): Pass new argument to
1620 scm_set_program_arguments.
1622 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1624 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1625 (scm_boot_guile): Call scm_set_program_arguments here, later than
1626 the old initialization.
1628 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1629 initialization procedure.
1630 - Delete in, out, err arguments; there are other perfectly good
1631 ways to override these when desired.
1632 - Delete result argument; this function shouldn't ever return.
1633 - Rename init_func argument to main_func, for less confusion.
1634 - Delete boot_cmd argument; main_func is more general.
1635 -Add 'closure' argument, to help people pass data to main_func
1636 without resorting to global variables.
1637 - Abort if reentered; don't bother returning an error code.
1638 - Call scm_init_standard_ports to set up the default/current
1639 standard ports; no need to pass them to scm_start_stack.
1640 - Remove code to evaluate the boot_cmd, and start the repl; let
1641 the user do something like that in main_func if they want.
1642 - Remove code to package up a return value; main_func can do any
1644 - Call exit (0), instead of returning.
1645 (scm_start_stack): Don't initialize the I/O ports here; that's
1646 weird. Delete in, out, err arguments. Move guts to
1647 scm_init_standard_ports, scm_stdio_to_port.
1648 (scm_init_standard_ports): New function, to set up current and
1649 default standard ports.
1650 (scm_start_stack, scm_restart_stack): Make these static.
1651 * init.h (scm_boot_guile): Adjust declaration.
1652 (scm_start_stack, scm_restart_stack): Remove externally
1653 visible declarations for these.
1654 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1656 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1657 written out several times in scm_start_stack.
1658 * fports.h: New declaration for the above.
1660 * feature.c (scm_set_program_arguments): New function.
1661 * feature.h: New declaration for the above.
1663 * ports.c: Formatting tweak.
1665 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1667 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1668 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1669 for obtaining the address of a car or cdr field. Motivation:
1670 &SCM_CXR make assumptions about the internal structure of the
1673 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1674 Motivation: see SCM_CXRLOC.
1676 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1677 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1678 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1679 Motivation: Safer use. Some other macros are defined in terms of
1680 these operations. If these are defined using the SCM_SETCXR
1681 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1682 to inefficiency and an <e1> with side-effects could potentially
1683 break. Also, these particular operations are heavily utilized in
1684 the garbage collector. In unoptimized code there will be a
1687 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1688 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
1689 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
1690 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
1691 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
1692 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1693 vports.c: Cleaned up use of pairs: Don't make any special
1694 assumptions about the internal structure of selectors and
1695 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1696 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1697 (Among other things, this change makes it easier to build Guile
1698 with certain compilers which have problems with casted lvalues.)
1700 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1702 * stacks.c: Improve selection of relevant stack frames when making
1703 a stack object. Introduce one level of indirection in the stack
1704 object to make it possible to "narrow" to a certain region of the
1705 stack. This facilitates making use of more clever algorithms (not
1706 implemented) for selecting relevant frames and gives a cleaner
1707 design since selection of frames can be done independently of
1708 extraction of frames from the real stack.
1709 (scm_stack_id): Also take #t as argument which means look at
1712 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1713 Turn n_tail into an integer directly representing current number
1714 of frames in stack. Add field tail.
1716 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1718 * debug.c (scm_make_memoized): Made it available at scheme level.
1719 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1720 SCM_NIMP before applying heavier predicates in argument checking.
1721 (scm_local_eval): Also take memoized object as argument.
1723 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1724 aren't created with zero length, but should such a strange
1725 creature suddenly turn up...
1727 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1729 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1730 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1732 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1734 * variable.c (scm_make_variable): Make the name hint optional, as
1736 (anonymous_variable_sym): Renamed from variable_sym. All uses
1739 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1740 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1741 of scm_primitive_load_path was also changed to
1742 "primitive-load-path", from "%try-load-path". Callers changed.
1743 We'd like to respect the convention that a function named
1744 "try-mumble" should behave just like the function called "mumble",
1745 but return #f instead of signalling some error.
1746 * load.h: Rename prototypes.
1748 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1750 * print.c (make_print_state, grow_print_state), print.h: Modified
1751 the print state representation: Don't use a tail array for
1752 recording of circular references. Resizing of the print state
1753 structure invalidates the print state pointer. To avoid passing
1754 around an indirect print state reference to all printing
1755 functions, we instead let the print state reference a resizable
1758 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1760 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1761 Don't crash when passed an improper list terminated by a
1762 non-immediate value.
1764 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1766 Allocate data for structures on an eight-byte boundary, as
1767 required by the tagging system.
1768 * struct.c (alloc_struct): New function.
1769 (scm_make_struct, scm_make_vtable_vtable): Call it.
1770 * struct.h (scm_struct_n_extra_words): Bump to 3.
1771 (scm_struct_i_ptr): New "field".
1772 * gc.c (scm_gc_sweep): When we need to free the data, use the
1773 information stored by alloc_struct to find the beginning of the
1774 block allocated to the structure, so we can free it.
1776 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1778 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1781 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1782 (scm_debug_info): New member: id.
1784 * stacks.c: Stacks are now represented as structs; Stacks have an
1785 id given to them by `start-stack'.
1786 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1788 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1789 Changed stack representation.
1791 * debug.c (scm_procedure_name): Try procedure property `name' for
1792 compiled closures aswell.
1794 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
1796 * eval.c: scm_i_name moved to gsubr.c
1797 (scm_m_define): Record names of all kinds of procedure
1798 objects. (Earlier, only closures were recorded.)
1800 * procprop.h: Added declaration of scm_i_name.
1802 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1803 (scm_make_gsubr): Record names of compiled closures.
1805 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1807 * debug.c, debug.h: Removed obsolete code.
1809 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1810 stacks.c: Renamed regs --> scm_contregs.
1812 * print.c (scm_free_print_state): Cleanup print state before
1813 returning it to pool. It is better to do it here than in
1814 scm_prin1 since scm_prin1 is called often.
1816 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1817 s_set_source_property_x): Check that first argument is a pair or a
1820 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1821 scm_i_line, scm_i_column and scm_i_breakpoint global.
1823 * init.c: Added #include "backtrace.h" and #include "stacks.h".
1824 (scm_boot_guile_1): Added calls to scm_init_backtrace and
1827 * debug.h: Added debug object smob declaration and macro
1830 * configure.in: Build with backtrace.o and stacks.o if debug
1833 * Makefile.in: Added entries for new files: backtrace.c,
1834 backtrace.h, stacks.c and stacks.h.
1836 * symbols.c (scm_sym2ovcell): Fixed documentation.
1838 * _scm.h (min, max): Added.
1840 * async.c: Moved `min' macro to _scm.h.
1842 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1843 SCM_BACKTRACE_INDENT.
1845 * eval.c: Added new debug options `maxdepth' and `indent'.
1847 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
1849 * print.h: Added selector SCM_PRINT_STATE.
1851 * print.c: New functions: scm_make_print_state,
1852 scm_free_print_state.
1854 * print.h: Added declarations for scm_make_print_state,
1855 scm_free_print_state.
1857 * debug.c (scm_m_start_stack): New acro.
1859 * debug.h: Small cleanup.
1861 * init.c (scm_boot_guile_1): Moved scm_init_debug below
1864 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

1889 More prototype-related changes from Marius Vollmer:
1890 * gdb_interface.h: Wrapped header file in #ifdef/#endif
1891 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
1892 * ports.h (ptobfuns): Added prototypes. This means some casting in
1894 * fports.c: Added casts for initializations, since the functions
1895 are defined to take FILE * as their stream argument, not SCM.
1896 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
1897 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
1898 to `char *str_data' to conform to prototype.
1900 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1902 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
1904 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
1906 * stime.c, stime.h: use SCM_P method.
1908 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1910 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
1911 be given at least two arguments. Insist that lst's last element
1912 be a list, but don't make any requirements of its predecessors.
1914 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1916 * eval.c (scm_nconc2last): Revert last change; there seems to be
1917 other stuff going on here.
1919 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1921 * eval.c (scm_nconc2last): Make sure that each element of lst
1922 (which is a list of argument lists, except for the tail) is a
1923 proper list, i.e., finite and terminated by '().
1925 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1927 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
1930 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
1931 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
1934 * vectors.c (scm_make_vector): Fill vectors with the undefined
1935 value, to help make Guile Scheme code more portable to other
1938 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
1939 * symbols.h, tags.h: Doc fixes.
1941 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
1943 * async.c (scm_take_signal): Doc fixes.
1945 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
1947 * numbers.c (scm_divbigint): When the remainder is zero, we don't
1948 want to subtract it from the modulus; we just want to leave it
1951 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
1953 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
1956 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
1958 * throw.c (scm_catch_apply): Finished implementation of
1961 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
1963 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
1965 (scm_init_filesys): set "i/o-extensions" feature.
1968 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
1970 * Makefile.in (root.o): Correct dependencies.
1972 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
1974 * Makefile.in: Added dependency entry for root.o.
1976 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
1977 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
1979 * init.c (scm_start_stack): Set initial root continuation number
1982 * procs.c: New function: scm_thunk_p.
1984 * procs.h: Added declarations of scm_thunk_p.
1986 * root.c: Renamed `call-with-new-root' -->
1987 `call-with-dynamic-root'.
1988 (cwdr): Removed allocation of new root state. This should be done
1989 separately by use of scm_make_root.
1990 (scm_apply_with_dynamic_root): New function: Does what it
1991 sounds like. Needed when spawning threads.
1993 * root.h: Added member last_debug_frame to root state.
1994 Added #include "libguile/debug.h"
1996 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
1997 arguments. The motivation is that code in root.c needs catch
1998 functionality, and we want to avoid code duplication.
1999 New functions: scm_catch, scm_lazy_catch. These are wrappers for
2000 scm_catch_apply. scm_lazy_catch is intended to introduce catch
2001 handlers that run without popping the stack into the dynwind
2004 * throw.h: Added prototypes for scm_catch_apply and
2007 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2009 * root.h (scm_root, scm_set_root): Decouple thread support details
2010 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
2011 SCM_SET_THREAD_LOCAL_DATA.
2013 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
2014 and tortoise scanning loop.
2016 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
2018 * Makefile.in: Rebuild dependencies.
2020 * libguile.h: #include "libguile/print.h" before "smob.h", since
2021 the latter uses the print_state structure.
2023 * throw.c (scm_ithrow): Use the correct variable when checking to
2024 see if a given element of scm_dynwinds is a valid catch.
2026 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
2027 structure, abort; don't just silently ignore the garbage.
2029 * _scm.h: #include "print.h" here, since it seems to be used just
2031 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
2032 strports.c, unif.h: Don't #include "print.h".
2034 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2036 * feature.h (scm_loc_features): Removed external declaration.
2037 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
2039 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2041 * feature.c (scm_init_feature): Added threads feature (needs to be
2042 initialized here, since features doesn't exist when
2043 scm_init_threads is called).
2045 * libguile.h: Added #include "libguile/../threads/threads.h".
2046 (This is a kludge to get thread support working. This should be
2049 * configure.in, acconfig.h: Added flags for thread support.
2051 * scmsigs.c: Define `signal' to be `pthread_signal' if using
2054 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
2055 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
2058 * _scm.h: Added conditional #include "threads.h"
2060 * __scm.h (SCM_ASYNC_TICK): Added call to macro
2061 SCM_THREADS_SWITCHING_CODE.
2063 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
2064 allocate the basic dynamic root object.
2065 (scm_boot_guile): Added call to scm_init_root.
2067 * root.c, root.h: Added root smob.
2068 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
2069 functions: Implements dynamic roots mostly according to spec in
2070 SCM manual. Main difference is that the second argument is a
2071 throw handler rather than an error "thunk".
2073 * root.h: Added declaration of scm_init_root.
2075 * root.c: Added #include "genio.h", #include "smob.h", #include
2076 "pairs.h", #include "throw.h", #include "dynwind.h", #include
2078 (scm_init_root): Added #include "root.x".
2080 * throw.c: Added #include "stackchk.h"
2081 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
2082 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
2083 can be used in scm_call_with_new_root; Added reenabling of stack
2084 checking when catching a throw.
2086 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
2088 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
2090 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
2091 element is not found, as per R4RS.
2093 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2095 * list.c: Doc fixes throughout.
2097 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2099 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
2100 declare the char * to be const. Avoids a warning in rgx.c.
2102 * ports.h: spelling fix.
2104 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
2107 * load.c (scm_sys_try_load_path): throw an error if file not found
2108 (like it says it in NEWS).
2110 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2112 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
2113 PROPS slot to '(), not #f; it's an empty alist.
2115 * throw.h, throw.c: Use SCM_P instead of #if hair.
2117 Remove special support for uncaught throws; see throw.c for
2119 * throw.c (uncaught_throw): New function.
2120 (scm_ithrow): Call uncaught_throw if we don't find a throw
2121 target; don't mess with scm_bad_throw_vcell.
2122 (scm_bad_throw_vcell): Variable deleted.
2123 (scm_init_throw): Don't initialize it.
2125 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
2128 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2130 * numbers.c (scm_istr2int): If the number is short (as most
2131 numbers are), just call scm_small_istr2int to deal with it.
2132 (scm_small_istr2int): New function, created by un-#ifdefing the
2133 non-bignum version of scm_istr2int and renaming it.
2135 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
2137 * load.c (scm_sys_try_load): don't check whether value returned
2138 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
2139 Change the Scheme name from %try-load to primitive-load.
2141 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
2142 Can avoid passing a message, allowing it to be derived in the
2143 error handler (e.g., if we want to throw to the key both from
2146 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
2148 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
2149 references now have a new appearance which is more compact and
2150 also gives a clue about what the target of the reference is.
2151 By setting parameters in the print state, more fancy printing can
2152 be achieved. This is used by the (not yet commited) backtrace
2155 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
2157 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
2160 * print.c: Added #include "struct.h". Removed function
2163 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
2164 scm_iprin1. Removed prototype for scm_prlist.
2166 * arbiters.c (prinarb),
2167 async.c (print_async),
2168 debug.c (prindebugobj, prinmemoized),
2169 eval.c (prinprom, prinmacro),
2170 filesys.c (scm_fd_print, scm_dir_print),
2172 mallocs.c (prinmalloc),
2173 numbers.c, numbers.h (scm_floprint, scm_bigprint),
2174 smob.h (scm_smobfuns),
2175 srcprop.c (prinsrcprops),
2177 unif.c, unif.h (scm_raprin1, rapr1),
2178 variable.c (prin_var): Changed argument `int writing' to
2179 `scm_print_state *pstate'.
2181 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
2182 that it will be called before scm_init_print.
2184 * print.c (scm_prin1): Print states are now allocated when calling
2185 scm_prin1 and then passed around to all printing functions as an
2186 argument. A cache `print_state_pool' enables reuse of print
2188 (scm_make_print_state): New function.
2189 (scm_iprin1): Adaption to print states.
2190 (scm_iprlist): An initial "hare and tortoise" scan brings down
2191 time complexity to O (depth * N). (Better time complexity will be
2192 achieved when the printing code is completely rewritten.)
2194 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2196 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
2197 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
2198 it gets done whether or not the cache variable has a value.
2200 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2202 Distinguish #f and ().
2203 * __scm.h: #undef SICP.
2204 * pairs.h (SCM_EOL): Delete this definition, equating it with
2206 * tags.h (SCM_EOL): Give it a new definition here; I think I found
2207 the value it used to have. Doc fixes, too.
2209 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
2211 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
2212 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
2213 Lord's implementation of structs, allowing for tail arrays as
2214 described in the manual. Also fixed some bugs. (Both the interface
2215 and the implementation should be improved.)
2217 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
2219 * print.c, print.h: Closures now print like #<procedure foo (x)>.
2220 People who whish to see the source can do `(print-enable 'source)'.
2221 Removed #ifdef DEBUG_EXTENSIONS.
2223 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2225 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
2226 integer (assuming for now accepting an integer is a good thing).
2228 * error.c, fports.c: replace use of %S in lgh_error args with %s.
2229 %S will be used instead for write'ing arguments.
2231 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
2232 asserts. fix a few other asserts.
2233 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
2234 scm_uniform_vector_ref, scm_array_set_x,
2235 scm_dimensions_to_unform_array): change args in
2236 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
2237 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
2238 scm_substring_fill_x): likewise.
2239 gsubr.c (scm_gsubr_apply): likewise.
2240 eval.c (SCM_APPLY): likewise.
2242 * eval.c (4 places): replace scm_everr with lgh_error or
2245 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
2246 scm_memory_error): new procedures.
2247 scm_everr: deleted. can use scm_wta, dropping first two args.
2248 scm_error: convert NULL subr to SCM_BOOL_F.
2250 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
2253 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
2256 * error.c, error.h: new error keys: scm_arg_type_key,
2257 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
2259 scm_wta: reimplement using lgh_error instead of scm_everr.
2261 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
2263 * gdbint.c: scm_lread now has one more argument.
2265 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
2266 scm_port_\1; Added mutator scm_set_port_filename_x (used when
2267 loading source from non-file ports, which, e. g., happens when
2268 using the Emacs interface).
2270 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
2273 * read.c: Added code for recording of positions of source code
2274 expressions; New functions: recsexpr, scm_lreadrecparen;
2275 _scm_make_srcprops --> scm_make_srcprops
2276 (scm_flush_ws): Removed updating of positions counters. This work
2277 is already done by scm_gen_getc
2279 * read.h: Added prototype for scm_lreadrecparen
2281 * print.c: Added #include "alist.h"
2283 * eval.c: Added #include "hash.h"
2285 * eq.c: Added #include "ramap.h"
2287 * options.c: Documentation fixes.
2289 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.

2291 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
2292 --> scm_make_srcprops
2294 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
2295 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
2296 function calls in the definition of the whash access macros.
2298 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
2300 * init.c (scm_boot_guile): Add level of indirection to
2301 scm_boot_guile_1() to ensure that stack base pointer is properly
2302 initialized. There was no guarantee that variable i was the
2303 highest/lowest variable on stack (i.e. the call frame of
2304 scm_boot_guile was not completely protected from gc).
2306 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
2308 * ports.h (scm_port_table): put back file_name, it will be used to
2309 support debugging. Undo related changes in fports.c, ioext.c,
2312 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2314 * ports.h (scm_port_table): remove file_name member for now, it seems
2316 * fports.c (scm_open_file): don't set file_name in PTAB.
2317 (prinfport): don't use file_name in PTAB.
2318 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
2319 * ports.c (scm_add_to_port_table): don't intialize file_name.
2320 (scm_port_file_name): remove for now.
2321 * gc.c (scm_gc_mark): don't mark PTAB file_name.
2323 * fports.h (scm_mkfile): prototype deleted.
2324 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
2326 * debug.c, unif.c: use scm_out_of_range instead of
2327 wta for range errors (ASSERT still needs work).
2329 * error.c, error.h (scm_out_of_range): new procedure.
2331 * error.c, error.h (scm_out_of_range_key): new key.
2333 * posix.c (scm_sync): #else was missing.
2335 * error.c, error.h: append _key to names scm_num_overflow and
2338 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
2339 of consing an empty list.
2340 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
2341 of macros, saves code and string space.
2342 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
2343 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
2344 lower case. Rename scm_syserror_m to scm_syserror_msg.
2345 error.h: prototypes for new procedures.
2347 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
2349 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
2351 * error.c, error.h: setup scm_num_overflow key.
2353 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
2354 Remove definition of SCM_OVSCM_FLOW.
2356 * fports.c (scm_open_file): use SCM_SYSERROR_M.
2358 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
2359 explicit message and args.
2361 * error.c, error.h, __scm.h: change system_error_sym to
2364 * error.c (system_error_sym): remove leading %% from the Scheme name
2367 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
2369 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2371 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
2372 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
2373 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
2374 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
2375 renamed. (These were introduced by unsupervised name
2378 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2380 * print.c: Added code for detection of circular references during
2381 printing. (init_ref_stack, grow_ref_stack): New functions. Added
2382 a hook for printing of closures (accessible via print options).
2383 This leads to a split of calls to scm_iprin1 into two classes:
2384 elementary print operations (e. g. the code which prints a smob)
2385 still use scm_iprin1 while top level calls (like scm_display) use
2386 scm_prin1. scm_prin1 begins by clearing the data structure used
2387 to record reference information.
2389 * print.h: Added declarations of scm_prin1 and scm_prlist.
2391 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
2393 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
2395 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
2397 * error.c (err_head): scm_iprin1 --> scm_prin1
2399 * debug.c: Adjusted header comment.
2403 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2405 * strerror.c: Doc fix.
2407 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2409 * gdbint.c (gdb_read): Now possible to run during GC.
2410 (unmark_port, remark_port): New functions.
2412 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
2414 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
2415 of allocating a new string object. Also, increase size by
2416 the factor 2 instead of 1.5.
2418 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
2420 * __scm.h (SCM_P): Corrected to run under traditional C.
2422 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
2425 * async.c: Calls to scm_sysintern corrected.
2427 * async.h (scm_async_clock): Redundant declaration removed.
2429 * continuations.c (scm_dynthrow): Redundant declaration removed.
2431 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
2432 Definition typos corrected.
2434 * debug.h: Missing declarations of functions in debug.c added
2437 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2438 Missing declarations to functions in eval.c added.
2440 * filesys.c: Possibly uninitialized variable rv.
2442 * gc.h (scm_object_addr, scm_unhash_name): Missing
2443 declarations of functions defined in gc.c added.
2445 * genio.c: Possible typos str_data -> wstr_data. ???
2447 * genio.c: Possibly unintended shadowing of local variable
2448 `int c' (gotos out of scope of inner `c'). ???
2450 * init.c: Uninitialized `SCM last' may be used.
2452 * ioext.h: (scm_sys_isatty_p): Typo.
2454 * list.h (scm_list_head): Missing prototype for function in
2457 * numbers.c (scm_two_doubles): Changed from extern to static
2458 (is used only within numbers.c).
2460 * numbers.h: Repeated declarations removed.
2462 * ports.h (scm_close_all_ports_except): Declaration for the
2463 function defined in ports.c added.
2465 * posix.h: Missing declarations added.
2467 * procs.h (scm_make_subr_opt): Missing declaration added.
2469 * socket.h (scm_sys_gethost): Missing declaration added.
2471 * socket.h: Redundant declarations removed (they are in fdsocket.h).
2473 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
2474 Missing declarations added.
2476 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
2478 * struct.c: Uninitialized variable `SCM answer' may be used.
2480 * unif.c (l2ra): Declaration prototype.
2482 * unif.c (scm_array_equal_p): Dummy definition removed (it is
2483 defined in ramap.c).
2485 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
2486 Redundant declarations removed (they are in ramap.h).
2488 * variable.h (scm_make_udvariable,
2489 scm_make_undefined_variable): Declaration corrected to
2490 correspond variable.c.
2492 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
2493 Missing declarations added.
2495 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
2497 * Makefile.in (distclean): Don't forget to delete fd.h.
2499 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2501 * fd.h.in, tags.h: Trivial cleanups.
2503 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
2504 marksweep.h just declared functions from gc.c.
2505 * gc.h, libguile.h: Don't #include "marksweep.h".
2506 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2507 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
2508 dependencies updated.
2510 * libguile.h: Don't #include "files.h"; it's been deleted.
2512 * files.c (scm_sys_delete_file): Moved to filesys.c.
2513 File is now empty; deleted.
2515 * filesys.c: scm_sys_delete_file is now here. Remove
2516 #if's; they seem to rely on remnants of an old portability
2517 regimen. If the problems come up again, solve them properly,
2518 using autoconf. Specifically: Don't test M_SYSV, and #define
2519 remove to be unlink if it's #defined; don't use remove just
2520 because HAVE_STDC_HEADERS is #defined.
2521 * filesys.h: Add declarations for scm_sys_delete_file.
2522 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2523 files.o, files.h, files.c, and files.x.
2524 * init.c: Don't #include "files.h", and don't call scm_init_files.
2526 Use SCM_P instead of PROTO; the latter intrudes on the user's
2528 * params.h: Deleted; definition of SCM_P moved to...
2529 * __scm.h: ... here, where it replaces PROTO macro.
2530 * libguile.h, smob.h: Don't #include "params.h".
2531 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
2532 smob.h: Fix prototypes accordingly.
2533 * Makefile.in: Update dependencies.
2534 (inner_h_files): Remove params.h.
2536 * gc.c: #include "gc.h"; every module should include its header,
2537 to let the compiler cross-check the declarations against the
2540 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2541 simpos.h: #include "libguile/__scm.h".
2543 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2545 * init.c: Don't forget to #include smob.h and init.h.
2546 * Makefile.in: Dependencies updated.
2548 * smob.h: Use PROTO instead of #if __STDC__.
2550 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2552 * __scm.h: Doc fixes.
2554 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2555 <angles>; this allows `make depends' to work properly.
2557 * libguile.h: #include smob.h and pairs.h before the others; they
2558 define typedefs used by other headers.
2560 C files should #include only the header files they need, not
2561 libguile.h (which #includes all the header files); the pointless
2562 recompilation was wasting my time.
2563 * Makefile.in (all .o dependency lists): Regenerated.
2564 * libguile.h: Don't try to get a definition for size_t here...
2565 * __scm.h: Do it here.
2566 * _scm.h: Since this is the internal libguile header, put things
2567 here that all (or a majority) of the libguile files will want.
2568 Don't #include <libguile.h> here; that generates dependencies on
2569 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2570 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2571 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

2667 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
2668 * weaks.c: Get "weaks.h".
2670 * stackchk.h: #include "libguile/debug.h",
2672 * print.h, read.h: #include "options.h", since everyone who uses
2673 either of these files will need that.
2675 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2676 anyone who uses this file will need them to define the smob
2677 printing functions. Also, get markers.h, since people will need
2678 to #define the mark functions.
2680 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2681 * ports.h: ... to here.
2683 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2684 don't rely on archaic C default type rules.
2686 * fports.h: #include "libguile/ports.h", since you need that in
2687 order to parse this.
2689 * genio.h: #include "libguile/print.h", because you need that to
2690 parse this; don't bother #including "ports.h", since print.h gets
2693 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2695 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2696 this; it's now a reference to an element of *scm_root.
2698 * debug.h: Don't #include "options.h"; the compiler won't be able
2699 to find that once the headers are installed; instead, #include
2700 "libguile/options.h".
2701 * gc.h: Same, with marksweep.h.
2702 * mbstrings.h: Same, with symbols.h.
2703 * scmhob.h: Same, with _scm.h.
2704 * smob.h: Same, with params.h.
2706 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2707 C files; there's no need for this, and it forces recompilations
2710 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2712 * error.c (scm_error): declare scm_error_callback.
2714 * error.h: prototype for scm_error_callback.
2716 * __scm.h: define lgh_error.
2717 (SCM_SYSERROR): redefine using lgh_error.
2719 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2721 * error.c (scm_error): new procedure.
2723 * error.h: prototype for scm_error.
2725 * Makefile.in (install): install scmconfig.h from the current
2726 directory, not $(srcdir).
2728 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2730 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2731 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2732 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
2733 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,

2738 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2739 vports.h, weaks.h: #include "libguile/__scm.h", not
2740 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2741 dependencies are within libguile properly.
2743 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2745 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2746 when scmconfig.h doesn't exist.
2748 * load.c (scm_sys_try_load): Correct spelling.
2750 * feature.c (scm_loc_features): Make this static.
2752 * Makefile.in (libpath.h): Omit trailing slash from path. We
2753 shouldn't require it of users, so why put it here?
2755 Move code to initialize and search %load-path from ice-9 to C
2756 code, so we can use the load-path to find the ice-9 boot code;
2757 this makes it easier to run Guile without installing it. See
2758 corresponding changes in guile/Makefile.in.
2759 * feature.c: Move stuff concerned with the load path to load.c.
2760 (scm_compiled_library_path): Deleted.
2761 Don't #include libpath.h here.
2762 * feature.h: Don't mention scm_compiled_library_path.
2763 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2764 <sys/stat.h>, and <unistd.h> (if present).
2765 (R_OK): #define if the system hasn't deigned to.
2766 (scm_loc_load_path): New variable.
2767 (scm_init_load_path, scm_sys_search_load_path,
2768 scm_sys_try_load_path): New functions.
2769 (scm_init_load): Initialize scm_loc_load_path to point to the
2770 value cell of the Scheme %load-path variable.
2771 * load.h: Add declarations for scm_sys_search_load_path,
2772 scm_sys_try_load_path.
2773 * init.c: Call scm_init_load_path.
2774 * Makefile.in (feature.o, load.o): Dependencies updated.
2776 * load.c, load.h: Rewrite using PROTO macro.
2778 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2780 * gc.c (scm_cellp): New function: C predicate to determine if an
2781 SCM value can be regarded as a pointer to a cell on the heap.
2783 * gc.h: Added declaration of scm_cellp.
2785 * gdb_interface.h: New file: The GDB interface header from the GDB
2788 * gdbint.c: New file: GDB interface.
2790 * gdbint.h: New file: GDB interface.
2792 * libguile.h: Added #include <libguile/gdbint.h>.
2794 * init.c (scm_boot_guile): Added scm_init_gdbint.
2796 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2797 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2798 found if object files and source are kept separate).
2800 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2802 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2804 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2806 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2807 TK_SRC_DIR; they're not relevant any more.
2809 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2810 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2812 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2814 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2815 search path, so we can find the <libguile/MUMBLE.h> headers.
2817 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2819 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2820 implicit in the .c.o rule.
2821 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2824 Put the library path in a header file, instead of passing it on
2825 the command line in every compilation.
2826 * Makefile.in (libpath.h): New target.
2827 (feature.o): Depend on libpath.h.
2828 (clean): Delete libpath.h.
2829 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2830 * feature.c: ... #include "libpath.h" here.
2831 * .cvsignore: Ignore libpath.h.
2833 Don't install the unwashed masses of Guile header files in the
2834 main #include path; put most of them in a subdirectory called
2835 'libguile'. This avoids naming conflicts between Guile header
2836 files and system header files (of which there were a few).
2837 * Makefile.in (pkgincludedir): Deleted.
2838 (innerincludedir): New variable; this and $(includedir) are enough.
2839 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
2840 (installed_h_files): Divide this up. Now this variable lists
2841 those header files which should go into $(includedir) (i.e. appear
2842 directly in the #include path), and ...
2843 (inner_h_files): ... this new variable says which files appear in
2844 a subdirectory, and are referred to as <libguile/mumble.h>.
2845 (h_files): List them both.
2846 (install): Create innerincludedir, not pkgincludedir. Put
2847 the installed_h_files and inner_h_files in their proper places.
2848 (uninstall): Corresponding changes.
2849 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2850 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2851 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
2852 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,

2857 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2858 vports.h, weaks.h: Find __scm.h in its new location.
2859 * __scm.h: Find scmconfig.h and tags.h in their new locations
2860 (they're both "inner" files).
2862 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
2864 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
2866 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2868 * posix.c: Doc fixes.
2870 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
2872 * socket.c: Don't include a prototype for inet_aton; just use a
2873 K&R style declaration, to avoid warnings but minimize the chance
2874 of conflicts with the system.
2876 On NextStep, <utime.h> doesn't define struct utime, unless we
2877 #define _POSIX_SOURCE before #including it.
2878 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
2879 * acconfig.h: New comment text for above CPP symbol.
2880 * configure.in: Call it.
2881 * posix.c: #define _POSIX_SOURCE if it seems necessary.
2883 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
2885 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
2886 testing for __EMX__.
2888 * posix.c: #include <libc.h>, if it exists.
2890 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
2891 don't even know if the latter exists.
2893 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
2894 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
2895 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
2897 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
2899 (scm_init_posix): Use them when initializing the Scheme constants
2902 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2904 * Makefile.in (libdir, includedir, bindir): Use the
2905 autoconf-supplied values, instead of deriving them ourselves.
2906 (pkgincludedir, datadir, pkgdatadir): New variables.
2907 (install, uninstall): Put the header files in a special
2908 subdirectory, not in the main search path.
2910 * Makefile.in (ALL_CFLAGS): Provide the proper value for
2911 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
2913 * Makefile.in (IMPLPATH): Deleted; never used.
2915 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
2916 on the Tcl/Tk source any more.
2917 (INCLUDE_CFLAGS): Remove references to the above.
2919 * Makefile.in (version.o): Corrected dependencies.
2921 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
2923 * libguile.h: #include "version.h"
2925 * init.c (scm_boot_guile): Call scm_init_version.
2926 * gscm.c (gscm_run_scm): Call scm_init_version.
2928 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
2929 GUILE_VERSION): AC_DEFINE these.
2930 (acconfig.h): #undef the above symbols.
2932 * Makefile.in (libobjs): Add version.o.
2933 (installed_h_files): Add version.h.
2934 (c_files): Add version.c.
2935 (gen_c_files): Add version.x.
2936 (version.o): New rule.
2937 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
2938 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
2939 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
2940 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
2941 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
2942 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
2943 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
2944 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
2945 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
2946 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
2947 weaks.o): Add version.h to dependency lists.
2948 (markers.o): Remove duplicate rule.
2950 * version.h: New file.
2952 * version.c: New file.
2954 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2956 * symbols.c (scm_strhash): scm_downcase is now a function, not an
2957 array; use it appropriately. Since GCC is quite happy to
2958 subscript functions, it never warned us about this; we should use
2959 -Wpointer-arith in the future. I guess we never tested
2962 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2964 * socket.c: Doc and copyright fixes.
2966 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2968 * debug.c: Fixed and improved gdb support.
2970 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2972 * socket.c: Added declaration of inet_aton to avoid compiler
2973 warning. (Hope this solution is correct.)
2975 * stime.c: Added declaration of ftime. (This is missing in
2978 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
2980 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2982 * Makefile.in (c_files): add strerror.c.
2984 * strerror.c: new file from Emacs' sysdep.c.
2985 maybe configure should also check for sys_errlist.
2987 * configure.in (AC_REPLACE_FUNCS): add strerror.
2989 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2991 * debug.c (scm_init_debug): Added initialization for
2992 scm_evaluator_traps.
2994 * debug.h, debug.c: Various name changes.
2995 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
2996 "debug-options-interface". See commentary in options.c.
2998 * options.h, options.c: Options now have documentation strings.
2999 Also added a long explanatory commentary.
3001 * eval.c, print.h, print.c, read.h, read.c: Modifications to
3004 * gscm.c, init.c, root.c, throw.c: Bug fixes:
3005 last_debug_info_frame is now updated in all cases.
3007 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
3010 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3012 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
3013 Added option STACK_CHECKING.
3015 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3017 * Makefile.in: Added {debug,options,srcprop}.{h,c}
3019 * __scm.h: Removed symbols for debugging support.
3021 * acconfig.h: Added symbols for debugging support.
3023 * configure.in: Added user option for debugging support.
3024 --enable-debug will include the debugging code into libguile.a.
3026 * continuations.c (scm_make_cont): Enlarged the #if 0 around
3027 scm_relocate_chunk_to_heap.
3029 * debug.c: New file: low-level debugging support. It also
3030 includes support for debugging with gdb. (The extensions to gdb
3031 are written by Per Bothner at Cygnus.)
3033 * debug.h: New file: low-level debugging support.
3035 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
3036 argument pairs. Extensive modifications to the debugging
3037 evaluator. Added "SECTION:" commentaries to clarify what happens
3038 when, during double compilation. Renamed EVALIMP --> EVALIM.
3039 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
3040 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
3041 the beginning of the file. New procedure: scm_unmemocopy.
3042 Added some global state variables needed by the debugging
3043 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
3044 check_entry, check_apply, check_exit, debug_options and
3045 evaluator_traps. New acro: undefine.
3047 * eval.h: Renamed EVAL --> XEVAL.
3049 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
3050 --> scm_make_weak_key_hash_table.
3052 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
3053 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
3055 * libguile.h: Conditionally include debug.h
3057 * objprop.c (scm_object_properties, scm_set_object_properties_x):
3058 scm_object_properties shouldn't return handle. `handle' now gets
3059 initialized in scm_set_object_properties_x. scm_object_properties
3060 doesn't any longer create an entry in scm_object_whash.
3062 * options.c: New file: handling of run time options.
3064 * options.h: New file: handling of run time options.
3066 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
3068 * print.c: New procedure: scm_print_options
3070 * print.h: Defines for print options.
3072 * read.c: New procedure: scm_read_options
3074 * read.h: Defines for reader options.
3076 * root.h: Added scm_source_whash among scm_sys_protects.
3078 * srcprop.c: New file: source properties.
3080 * srcprop.h: New file: source properties.
3082 * throw.c (jbsmob): Jump buffers are now correctly allocated.
3083 (Bug found by A. Green.)
3085 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3087 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3089 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
3091 * libguile.h: #include "objprop.h"; I guess this was forgotten.
3093 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
3094 and should be called by the final client.
3096 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
3098 * gc.h: Use the PROTO macro when declaring functions.
3099 * gc.c: Use the PROTO macro when declaring static functions.
3100 Remove the CPP hair around function definitions.
3102 * gc.c (scm_init_storage): Initialize scm_asyncs.
3104 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
3105 preprocessor symbol; "__scm.h" is where it might get #defined.
3106 * __scm.h: Similar: #include <scmconfig.h> before testing
3109 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
3111 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
3113 * init.c (scm_boot_guile): Add init_func argument; call
3114 (*init_func) instead of calling scm_appinit; it's ucky to
3115 hard-code names for the user's procedures.
3116 * init.h (scm_boot_guile): Adjust declaration.
3118 * __scm.h (PROTO): New macro, for declaring functions with
3121 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
3122 eliminate all the __STDC__ conditionals.
3123 (scm_boot_guile): Add declaration.
3124 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
3125 Remove __STDC__ conditionals around function definitions; the
3126 declarations in init.h will provide the same information, more
3129 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
3130 complain about it in the error message; the error message is
3131 adequate without that note, and there's nothing the user can do
3134 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
3136 * Makefile.in (ancillary): Drop def.sed.
3138 * posix.c (scm_init_posix): Use numeric values, rather than
3139 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
3140 F_OK. The symbols aren't available on some systems, and I'm
3141 pretty sure their values are fixed by common widespread practice.
3142 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
3144 More functions unavailable on some systems.
3145 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
3146 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
3148 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3149 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
3150 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
3151 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
3152 stub that signals an error as the #else.
3154 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
3156 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
3158 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
3160 * unif.c: include ramap.h.
3162 * read.c (endif): case_insensative_p renamed case_insensitive_p.
3164 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
3166 * ports.c: include sys/ioctl.h.
3168 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
3170 * configure.in: check for sys/ioctl.h.
3172 * ports.c: include <malloc.h> not "malloc.h".
3174 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3176 * fports.c: remove ttyname and tmpnam declarations.
3178 * posix.c: fewer ttyname declarations.
3180 * fports.c: include <string.h> not "string.h".
3182 * init.c, ioext.c: include string.h and unistd.h.
3184 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3186 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
3187 genio.c, simpos.c, vports.c: include string.h.
3189 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
3191 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
3193 (scm_addr_buffer_size): change type from scm_sizet to int.
3194 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
3195 from scm_sizet to int.
3197 * error.c: include unistd.h.
3199 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
3202 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
3204 * __scm.hd, def.sed: deleted.
3206 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
3208 Changes for NeXT, suggested by Robert Brown.
3209 * configure.in: Call AC_TYPE_MODE_T.
3210 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
3211 NeXT. Put header file list in alphabetical order.
3212 * configure, scmconfig.h.in: Regenerated.
3213 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
3215 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
3218 * acconfig.h: New file, providing documentation for the CPP
3219 symbols defined in configure.in
3220 * acconfig-1.5.h: Removed; superceded by the above.
3222 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
3224 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
3226 * fports.c (scm_open_file): don't return #f, throw error.
3228 * ioext.c (fileno): renamed from %fileno.
3229 (soft-fileno): deleted.
3231 * ports.c (scm_port_revealed): don't need to check for -1 from
3233 (scm_set_port_revealed_x): return unspecified, not #f.
3235 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
3237 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
3239 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
3241 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
3243 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3245 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
3246 This is necessary on Ultrix, and doesn't hurt portability.
3248 * Makefile.in (dist-dir): New target, implementing a new dist system.
3249 (installed_h_files): Put in alphabetical order.
3250 Remove duplicate entries for markers.h and unif.h.
3251 (c_files): Remove duplicate entries for markers.c.
3252 (ancillary): Renamed from anillery; all uses changed. Remove
3253 PLUGIN; it's a directory, and needs special treatment in dist-dir.
3254 Remove all the ../doc/* files; doc/Makefile.in handles that.
3256 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
3258 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
3259 every if must have an else, or else the whole command has a
3260 non-zero exit code whenever the if's condition is false.
3262 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
3264 * posix.c: include string.h.
3266 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
3268 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
3271 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
3272 Remove leading % from scheme names.
3273 Do not return error values, call SCM_SYSERROR or similar.
3275 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
3277 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
3279 * struct.c (scm_init_struct): new file.
3281 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
3283 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
3284 (scm_list_head): added list-head for rapidly chopping argument
3285 lists off of longer lists (and similar).
3287 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
3289 * objprop.c (scm_object_property): assq the cdr of the whash
3290 handle for obj, not the handle itself.
3292 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
3294 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
3295 weak hash tables last of all marking to avoid an obscure gc bug.
3296 WARNING: circular lists stored in a weak hash table will hose us.
3298 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
3300 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
3301 new functions similar to scm_substring_move_left_x and
3302 scm_substring_move_right_x.
3304 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
3306 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
3309 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
3311 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
3313 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
3315 * strports.c (scm_strprint_obj): convenience function. C for
3316 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
3318 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
3319 removed to a separate library
3321 * init.c (scm_boot_guile): copied from guile-tcl.c.
3322 Initialization specific to tcl interpreters removed.
3324 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
3326 * ports.c (scm_ports_prehistory): size malloced here doesn't
3327 matter so long as it is non-0 (got rid of "* 4").
3329 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
3331 * gscm.h: gscm_mkarray eliminated (presumably was not being used
3332 since its definition was bogus).
3334 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
3336 * mallocs.[ch]: back again (for rx at least).
3338 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
3340 * ports.c: removed functions relating to the mapping between ports
3341 and descriptors. (That stuff is unix-specific and should be collected
3342 in a separate library).
3344 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
3345 (Tom Mckay@avanticorp.com)
3347 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
3349 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
3350 handled correctly (SCM_FREEP was applied to them) -- test for
3351 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
3352 being overwritten with #f. (brown@grettir.bibliotech.com)
3354 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
3356 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
3357 for a specific symbol or for all symbols.
3359 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
3361 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
3362 keys and weak values confused).
3364 Thu Mar 14 22:20:20 1996 Tom Lord <lord@beehive>
3366 * list.c (scm_last_pair): map '()=>'()
3368 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>
3370 * pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:
3371 Generalized assoc and hash-table functions.
3372 Factored pairs.c into multiple files.
3374 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
3376 * gscm.c (gscm_run_scm): got rid of objprop.
3378 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
3380 * genio.c (scm_getc):
3381 NOTE: fgetc may not be interruptable.
3383 * procprop.c (scm_stand_in_scm_proc):

3519 initialization to fix a race condition.
3521 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
