1 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
3 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
4 Don't screw up if we're interrupted.
5 * Makefile.in: Regeneradet.
7 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
9 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
11 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
12 we're not using AM_INIT_GUILE_MODULE any more.
13 * Makefile.in: Reneregated.
15 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
17 Functions for finding variable bindings, grace à Tim Pierce.
18 * * gh_data.c (gh_lookup, gh_module_lookup): New functions.
19 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
21 Get 'make dist' to work again.
22 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
23 * Makefile.in: Regenerated, like a surry without a fringe on top.
25 Changes for reduced Guile distribution: one configure script,
27 * configure.in, configure: Removed.
28 * acconfig.h, acinclude.m4: Moved to parent directory, where the
29 real configure script lives.
30 * Makefile.in, scmconfig.h.in: Regenerated.
32 * init.c: #include "script.h", to get prototype for script.c's
35 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
37 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
38 scm_must_malloc, not raw malloc.
40 * script.c (scm_compile_shell_switches): Dyke out debugging output
43 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
45 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
47 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
48 system has them. Hope this is safe. Previously
49 sys/timeb.h was included if HAVE_FTIME was defined or if
50 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
51 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
53 * ioext.c (scm_setfileno): add missing third argument to
56 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
58 * eq.c (scm_equal_p): Correctly compare strings of different
59 varieties. (Thanks to Tim Pierce.)
61 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
63 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
64 #! block comment must occur on a line all by itself.
66 Move most of the guts of shell command processing into libguile,
67 so guile.c can be very small (and eventuallly auto-generated. (I
68 mean, generated mechanically, not self-generated. Hmm.))
69 * guile.c, script.c, script.h: New source files.
70 * init.c (scm_boot_guile_1): Call scm_init_script.
71 * libguile.h: #include "script.h".
72 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
73 targets, for new executable.
74 (libguile_la_SOURCES): Mention script.c.
75 (modinclude_HEADERS): Add script.h.
76 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
77 not dynamic linking is enabled. This is because we're generating
78 executables now. Move CY_AC_WITH_THREADS call after those, so the
79 values of cy_cv_threads_libs captures the libs chosen above.
80 * Makefile.in, configure, aclocal.m4: Regenerated.
82 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
83 We don't maintain this interface any more, and it just confuses
86 * alloca.c: #include <scmconfig.h>, not <config.h>.
87 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
88 it'll get included in disties.
90 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
92 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
93 be distributed, because they confuse people.
94 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
96 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
98 * configure.in: check for presence of gethostent (not present on
100 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
101 * configure, scmconfig.h.in: Regenerated.
103 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
105 * backtrace.c (scm_backtrace): Split message string across
106 newlines properly. GCC is more tolerant of this than other
109 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
111 Merge threads directory into libguile.
112 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,

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

173 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
175 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
176 have S_IFSOCK. This is the case under Ultrix.
178 * posix.c (scm_status_exit_val, scm_status_exit_val,
179 scm_status_term_sig, scm_status_stop_sig): Modified to work with
180 Ultrix versions of WIFSTOPPED, etc., which assume that their
181 arguments are lvalues (hmm).
183 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
187 * throw.c: Doc fixes; rearranged.
189 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.

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

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

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

248 * putenv.c: new file, from sh-utils 1.12.
250 * posix.c (scm_environ): use malloc in place of scm_must_malloc
251 since allocation isn't for Scheme objects.
252 (scm_putenv): copy strings before placing in the environment.
254 * stime.c (scm_current_time): throw an error if time returns -1,
255 instead of returning #f.
256 (scm_get_internal_real_time, scm_get_internal_real_time): use
257 scm_long2num for return value instead of SCM_MAKINUM.
259 * stime.h: prototypes updated.
261 * stime.c (scm_time_in_msec): apparently unused, deleted.

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

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

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

329 * error.c (scm_init_error): #include cpp_err_symbols instead of
331 * posix.c (scm_init_posix): don't intern signal symbols. #include
334 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
336 * strop.c (scm_i_index): allow the lower bound to be equal to the
337 length of the string, so a null string doesn't always give an error.
339 * posix.h: new prototypes.
340 * posix.c (scm_status_exit_val, scm_status_term_sig,
341 scm_status_stop_sig): new functions, as in scsh. They break down
342 process status values as returned by waitpid.
344 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
346 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
347 configure doesn't know about it.
349 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
351 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
353 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
354 which defines C variables with global linkage.
356 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
358 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for

363 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
364 has time to check why this doesn't work well with continuations.
366 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
368 * Fix shell syntax error; some shells won't tolerate
369 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
371 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
373 * posix.c (scm_uname): throw an error if uname fails instead
376 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
378 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
381 * async.c (scm_ints_disabled): definition moved from error.c.

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

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

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

507 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
509 * configure.in: Added configuration option `guile-debug'.
510 Configure with --enable-guile-debug if you want a bunch of extra
511 functions used for debugging when developing Guile.
513 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
515 * procs.c (make-cclo): New undocumented debugging procedure: Make
516 compiled closure with internal procedure PROC and length LENGTH.
517 Only compiled if GUILE_DEBUG is defined.
519 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
521 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
523 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
525 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
526 with 3 or more args internally to the evaluator.
528 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
530 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
531 with 3 or more args internally to the evaluator. This is mainly
532 because we don't want to pass entry and exit points of the
533 debug support twice, but it also seems to increase the speed of
534 the evaluator for such calls (e. g. (+ 1 2 3)).
536 * * backtrace.c (scm_display_application): New procedure:
537 display-application; Set fancy printing parameters individually
538 for different types of display (backtrace, error, application).
539 (These should of course be customizable!)
541 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
542 clear the CHECK-flags.
544 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
546 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
548 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
550 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
551 from pairs with a GLOC in the car.
553 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
554 otherwise `symbol-hash' will behave badly.
555 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
556 we get segmentation fault!
558 * * symbols.c: Added #include "weaks.h". New functions:
559 `builtin-bindings' and `builtin-weak-bindings'. (These will be
560 moved to an extraneous library when we split libguile.)
562 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
564 * filesys.c (scm_stat): stat now takes fport arguments too as
565 documented in the manual.
567 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
569 * debug.c (scm_single_step): Bugfix: Call continuation with
570 scm_call_continuation instead of throwing to it.
572 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
574 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
575 argument wasn't declared to be optional.
577 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
579 * stime.c (scm_init_stime): Add feature "current-time".
581 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
583 * throw.h: prototype for scm_exit_status.
584 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
585 args to derive an exit status. Allows (quit) to work from a
587 (scm_exit_status): new function.
590 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
592 * eval.c (scm_deval): Removed some old code.
593 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
595 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
598 * symbols.c (msymbolize): Bugfix: Must initialize property list to
601 * procs.c: Introduce the existent C function scm_thunk_p at the
602 Scheme level as well.
604 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
606 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
607 used from C to easily lookup the value of a symbol in the current
610 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
612 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
613 scm_init_unif in this file. This will also fix a previous problem
616 * configure.in: Added AM_MAINTAINER_MODE
618 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
620 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
623 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
625 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
626 source files that are not always included in libguile but should
627 have their dependencies calculated by automake. This variable is
628 recognized by automake, no further magic is needed.
629 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
630 to deal exclusively with *.lo files, as it seems. The *.o files
631 are built automatically when the corresponding *.lo file gets
634 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
636 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
639 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
641 * unif.c (scm_array_set_x): minor change to argument error checking.
643 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
645 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
646 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
647 They should only be included in the library at configure.in's
649 (libguile_la_LDADD): Include the appropriate .lo files here.
650 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
651 so we know when to build them (and their .lo bretheren).
652 * configure.in (LIBLOBJS): New substituted variable. We let
653 configure decide which .o files to include in LIBOBJS, and then
654 put the corresponding list of .lo files in LIBLOBJS. The latter
655 is what we pass to libtool.
656 * Makefile.in, configure: regenerated.
658 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
660 * symbols.c (scm_sysintern0): New function. Contains the core of
661 old scm_sysintern but doesn't take a second value argument.
662 (scm_sysintern): Now uses scm_sysintern0.
663 (scm_sysintern_no_module_lookup): Renamed to
664 scm_sysintern0_no_module_lookup and doesn't take a second value
667 * symbols.h (scm_sysintern0: Added declaration.
669 * options.c (scm_init_opts): Use scm_sysintern0 instead of
670 scm_sysintern when interning option keys. Otherwise we risk
671 destroying the values of already interned variables.
673 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
674 scheme-level boolean (use SCM_NFALSEP).
676 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
678 (scm_backtrace): New function. (C version of old function from
679 boot-9.scm) Motivation: Make it possible to display backtraces
680 without depending on boot-9.scm. (I'm uncertain if this
681 motivation is good enough...)
683 * root.h (scm_root_state): Add member the_last_stack_var.
684 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
686 * root.c (mark_root): Mark scm_the_last_stack_var.
688 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
691 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
693 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
694 1. mark_lazy_catch didn't mark the smob.
695 2. Both functions above have standard variants:
696 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
697 free_lazy_catch --> scm_free0.
699 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
701 * throw.c (scm_internal_lazy_catch): New function.
702 (scm_lazy_catch): Rewritten to use it.
703 (scm_ithrow): Handle the new lazy catch representation.
704 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
705 that doesn't have a jmpbuf is a lazy catch clause.
706 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
707 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
708 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
710 (scm_init_throw): Register the new lazy-catch smob type.
711 * throw.h (scm_internal_lazy_catch): decl for new function.
713 * throw.c (scm_internal_catch): Doc fixes.
715 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
716 configure.in. Including this might cause problems if applications
717 that link against libguile include their own copies of alloca, but
718 if they're using autoconf, they should be adding libguile to LIBS
719 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
720 the copy in libguile, and things will be okay. (I think.)
722 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
724 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
726 strop.h: move prototypes too.
728 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
730 * posix.c (scm_init_posix): don't intern EINTR since it's now done
733 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
734 etc. I deleted them from filesys.c long ago, but didn't
735 notice they were here too (although ineffective since
736 sys/stat.h wasn't included).
738 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
740 * eval.c: Don't define alloca in GCC case. gcc will automatically
741 use __builtin_alloca if appropriate.
743 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
745 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
746 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
747 that values of automatic variables are preserved. See comments
748 for safe_setjmp for details.
750 Change from Thomas Morgan:
751 * variable.c: Include eq.h.
752 (var_equal): New function.
753 (variable_smob): Use var_equal as the discriminator for variables.
755 * throw.c (s_throw): Remove extraneous declaration.
757 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
758 * eval.c: Add necessary CPP cruft to support that.
759 * configure, Makefile.in, scmconfig.h.in: regenerated.
761 Change from Thomas Morgan:
762 * procprop.c (scm_procedure_properties): Convert the Scheme
763 boolean returned by scm_procedure_p into a C boolean before using
764 it as a condition for SCM_ASSERT.
765 (scm_procedure_property): Likewise.
767 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
768 indications of Unixness.
771 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
773 * * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
775 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
777 * read.c (scm_lreadr): use scm_misc_error to improve one of the
778 "unknown # object" error messages.
780 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
781 (scm_i_index) and declare it static. Add a 'direction' argument
782 to indicate what way the search should go.
783 (scm_i_index): throw out-of-range error instead of wrong-type-arg
785 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
786 strop.h: remove scm_i_index, scm_i_rindex prototypes.
788 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
790 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
792 * * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
793 to avoid clash with various scsh forks.
795 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
797 The following two changes (ramap.c, throw.c) are motivated by the
798 apparent unportability of forward declarations of static arrays of
799 the form `static foo bar[];'.
801 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
802 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
804 * throw.c (scm_throw): Moved above scm_ithrow.
806 * options.h: Removed the extern declarations of scm_yes_sym and
807 scm_no_sym since these are static.
809 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
811 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
813 * Makefile.am: remove AWK=@AWK@.
814 Add a rule for generating errnos.list.
815 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
817 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
818 don't extract errnos, just set a variable (avoids the
819 need to recompile error.c just because configure is run.)
821 * unif.h: update prototypes.
822 * unif.c (scm_uniform_array_read,write): change the offset and
823 length arguments to start and end, for consistency.
825 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
827 * ioext.h: update prototypes.
828 * * ioext.c (scm_read_delimited_x): replaces scm_read_line and
829 scm_read_line_x, it's a more general procedure using an
830 interface from scsh. read-line and read-line! are now defined
832 * Note that the new read-line trims the terminator
833 by default, previously it was appended to the returned string. An
834 optional argument specifies how to process the terminator (scsh
835 compatible). For the old behaviour: (read-line port 'concat).
836 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
837 returns a pair, but is converted to multiple values if the scsh
840 socket.h: update prototypes.
841 * socket.c (scm_recvfrom): for consistency with other procedures,
842 take start and end as separate optional arguments.
843 * (scm_recv, scm_recvfrom): don't allow the second argument
844 to be a size, only a buffer. Change the scheme names to
845 recv! and recvfrom!. Don't return the buffer.
847 * ioext.h, posix.h: move prototypes too.
848 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
849 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
850 "read.h" and "unif.h".
851 * ioext.c: include "chars.h"
853 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
855 * dynl.c: The dynamic linking and module registration functions
856 are now defined even when dynamic linking is not available for the
857 host system. Some of their functionality can be done without
858 dynamic linking; when it's really needed, they throw errors.
860 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
862 * configure.in: Only define DYNAMIC_LINKING when one of the system
863 dependent functions is detected.
864 * dynl.c (scm_dynamic_func): New function to get the address of a
865 function in a dynamic object.
866 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
867 produced by scm_dynamic_func as the thing to call.
869 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
871 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
872 (scm_register_module_xxx, scm_registered_modules,
873 scm_clear_registered_modules): New functions.
875 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
877 * symbols.c (scm_sysintern): Renamed to
878 scm_sysintern_no_module_lookup.
879 (scm_sysintern): New function to take the place of the old
880 scm_sysintern. It uses the current toplevel lookup closure to give
881 the symbol its value. This is a temporary hack to put packages
882 like gtcltk into their own module.
883 (scm_can_use_top_level_lookup_closure_var): New variable to tell
884 us whether `scm_top_level_lookup_closure_var' has been initialized
886 * eval.c (scm_init_eval): Set it.
888 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
890 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
891 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
893 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
895 * (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
896 scm_sys_dup): deleted: FD capability will be added to other
898 * Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
899 scm_fd_free, fd_smob, scm_intern_fd.
900 * (scm_open): renamed from scm_sys_open. Return a port instead of
901 an FD object. Make the mode argument optional.
902 * (scm_sys_create): deleted, it's just a special case of open.
903 (scm_init_filesys): move interning of constants O_CREAT etc.,
904 here (were previously using SCM_CONST_LONG macro).
905 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
907 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
908 include "fports.h" and <stdio.h>
909 (scm_stat, scm_select): don't support FD objects.
911 * error.h: adjust scm_syserror_msg prototype.
912 * error.c (scm_syserror_msg): take an extra argument for errno.
913 Using the global value didn't always work, since it could be
914 reset by procedure calls in the message or args arguments.
916 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
917 I don't understand why the check was there (and what about the
920 * strop.c (scm_string_copy): allow shared substrings to be copied.
922 * unif.h: corresponding change to prototypes.
923 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
924 recognize two new optional arguments: offset and length. Allow
925 the port argument to be an integer (file descriptor, for scsh).
926 Include <unistd.h> for "read" prototype.
928 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
930 * socket.c: don't include filesys.h.
932 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
934 * Makefile.am: add AWK=@AWK@ (?)
936 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
938 Add a rule to generate errnos.c from errnos.
939 * error.c (scm_init_error): include errnos.c.
940 * errnos_cnvt.awk: new file, converts the list of errno codes to
942 * errnos_get.c: new file.
943 * errnos.default: new file, contains errnos to try if they can't
944 be extracted from errno.h.
945 * configure.in: if using GCC, try and extract errno codes from
949 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
951 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
952 * Makefile.am: Made libguile into a libtool library.
953 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
954 Set libtool_libs to indicate that libguile is a libtool library.
955 See guile/ChangeLog for details.
956 * .cvsignore: ignore "*.lo", the libtool library objects.
958 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
960 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
961 use htons in getservbyport argument.
963 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
965 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
966 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
969 * objprop.c (scm_object_property): No need to take the CDR of the
970 value returned by scm_object_properties, since Aug 20 change.
972 * configure.in: When checking for struct linger, #include
973 <sys/types.h> as well as <sys/socket.h>. I've never known
974 <sys/types.h> to cause any portability problems, and Solaris's
975 <sys/socket.h> needs it.
976 * configure: Rebuilt.
978 I think the Sun compiler has chosen a perverse way to interpret
979 ANSI declarations combined with K&R definitions. We'll
980 appease it a little bit. But when it invades France, we fight.
981 * print.c (scm_iprlist): Change 'tlr' argument to an int.
982 * print.h (scm_iprlist): Here too.
983 * numbers.c (scm_divbigdig): Change definition to match
984 declaration in numbers.h.
985 * unif.c (scm_makflo): Change definition to match declaration in
988 * init.c (scm_boot_guile): Don't return the value of
989 scm_boot_guile_1. This function doesn't return a value;
990 scm_boot_guile_1 doesn't return a value (or return at all).
992 * eval.c (unmemocopy): Add a semicolon to appease the Sun
995 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
996 compile. I have a feeling this function is a bad idea anyway ---
997 one should always test for features, not systems.
999 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
1000 semicolons. Only pure luck kept this from being noticed earlier.
1002 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
1004 * socket.c (scm_recvfrom): Added missing semicolon.
1006 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1008 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
1009 the buffer and start and end positions for scsh networking
1012 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
1014 * configure.in: Revert previous change to this file; the problem
1015 is due to transient automake weirdness.
1016 * configure: Rebuilt.
1018 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
1019 PLUGIN/guile.libs. configure generates the latter from the former.
1020 * Makefile.in: Rebuilt.
1022 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
1023 need this if we install scripts, like guile-snarf.
1024 * configure: Rebuilt.
1026 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1028 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
1030 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
1032 * socket.c (scm_addr_vector): fix faulty scm_listify.
1034 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
1036 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
1037 style block comment is no longer considered an error.
1039 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
1041 * PLUGIN/guile.libs.in: New file.
1042 * PLUGIN/guile.libs: Removed from repository.
1043 * configure.in: Create PLUGIN/guile.libs from
1044 PLUGIN/guile.libs.in. This is for including additonal libraries
1045 needed for dynamic linking.
1046 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
1047 instead of PLUGIN/guile.libs.
1049 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
1051 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
1053 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
1054 occurrences of the given element from the list, not just the
1055 first. This is how the Emacs Lisp functions behave, how the
1056 analogous Common Lisp functions behave, and (I believe) how the
1057 older Maclisp functions worked. I realize that this change may
1058 break code, but it seemed better to break it before the Guile
1061 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
1062 Their prototypes were already present in gc.h, but they weren't
1064 (scm_init_storage): Initialize scm_protects.
1065 * root.c (scm_protects): New element of scm_sys_protects.
1067 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
1069 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1071 * libguile.h: Added #include "libguile/net_db.h".
1073 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
1074 30 change. That file is only meant for communication between the
1075 configuration process and load.c. If code linked against libguile
1076 wants to get at the paths mentioned in libpath.h, it can call
1077 functions declared in load.h.
1079 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1081 * libguile.h: Removed #include "libguile/fdsocket.h"
1083 * net_db.c: Added #include <sys/socket.h>.
1085 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
1087 * filesys.c (scm_input_waiting_p): use select in preference to
1088 FIONREAD, since the latter doesn't detect EOF.
1089 Throw error if neither select nor FIONREAD available.
1091 * socket.c (scm_connect): take a port, not a fd object.
1092 (scm_fill_sockaddr): throw an error if fam is not recognised.
1093 (scm_bind): use scm_fill_sockaddr.
1094 (scm_listen): take a port, not a fd object.
1095 (scm_accept): take and return a port. return #f in the car if
1096 address can't be got
1097 (scm_sock_fd_to_port): new procedure.
1098 (scm_socket): use scm_sock_fd_to_port.
1099 (scm_addr_vector): throw error if unrecognised address type.
1100 take an extra argument with the calling procedure name.
1101 (scm_getsockname): take a port. return #f if address can't be got.
1102 (scm_getpeername): take a port. return #f if address can't be got.
1103 (scm_recvfrom): take a port. return #f for address component if can't
1105 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
1106 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
1108 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
1110 * throw.c (scm_internal_catch): Make body funcs and handler funcs
1111 use separate data pointers, to allow them to be designed
1112 independently and reused.
1113 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
1114 Renamed from catch_body, catch_handler, and uncaught_throw; made
1116 (struct scm_catch_body_data): Renamed from catch_body_data; moved
1118 (scm_catch): Use the above.
1119 (scm_throw): Don't bother printing a message for an uncaught
1120 throw; we establish a default handler in init.
1121 * throw.h (scm_internal_catch): Prototype updated.
1122 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
1124 (struct scm_body_thunk_data): New structure, used as data
1125 argument to scm_body_thunk.
1126 * init.c (struct main_func_closure): New structure, packaging up
1127 the data to pass to the user's main function.
1128 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
1129 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
1130 scm_internal_catch to establish a catch-all handler, using
1131 scm_handle_by_message. This replaces the special-case code in
1133 (invoke_main_func): Body function for scm_internal_catch; invoke
1134 the user's main function, using the main_func_closure pointer to
1135 decide what to pass it.
1136 * root.c (struct cwdr_body_data): Remove handler_proc member.
1137 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
1138 (cwdr_handler): Removed.
1140 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1142 * socket.h (SCM_P): update bind prototype.
1143 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
1144 include "feature.h".
1145 (scm_socket): return a port, not a file descriptor object.
1146 include "fports.h" and <unistd.h>
1147 (scm_bind): take a port, not a file descriptor object.
1148 take an extra argument for address args.
1150 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
1151 INADDR_NONE, INADDR_LOOPBACK.
1153 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1155 * init.c: include net_db.h and not fdsocket.h.
1156 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
1158 * Makefile.am: corresponding changes.
1159 * socket.h: renamed from fdsocket.h, fix names.
1160 * net_db.h: renamed from socket.h, fix names.
1161 * socket.c: renamed from fdsocket.c.
1162 remove _sys from procedure names.
1163 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
1164 add "socket" to features list.
1165 * net_db.c: renamed from socket.c.
1166 remove _sys from procedure names.
1167 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
1168 add "net-db" to features list.
1169 include "net_db.h". don't include <sys/socket.h> or
1172 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1174 * tags.h (scm_tags): Removed comma at end of last enumerator.
1176 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
1178 Don't use GCC extensions to allocate space for debugging frames.
1179 (Here he goes again! Why do we put up with this?!)
1180 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
1181 an scm_debug_info structure, not an in-line array of them. Add
1182 'info' member, to say how many vect elements we've used, for eval
1184 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
1185 a new variable debug_info_end to mark the end of vect, instead of
1186 the address of the 'info' pointer itself.
1187 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
1188 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
1189 (SCM_APPLY): Explicitly allocate space for debug.vect.
1190 * debug.c (scm_m_start_stack): Same, for vframe.vect.
1191 * stacks.c: Adjusted for new debug frame structure.
1192 (RELOC_INFO, RELOC_FRAME): New macros.
1193 (stack_depth, read_frames): Use them, and new scm_debug_frame
1194 element 'info', instead of magically knowing that eval frames have
1195 an info pointer sitting after vect.
1196 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
1198 (scm_init_stacks): Formatting tweaks.
1200 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
1202 Give GCC more control flow information, so it can be sure that
1203 variables aren't used uninitialized.
1204 * error.h (scm_error, scm_syserror, scm_syserror_msg,
1205 scm_sysmissing, scm_num_overflow, scm_out_of_range,
1206 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
1207 scm_misc_error): Tell GCC that these functions never return.
1208 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
1209 out the field type, call abort if SCM_ASSERT returns, to placate
1211 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
1212 scm_wta ever returns. We can't handle this case anyway, and this
1213 gives the optimizer more information.
1214 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
1215 scm_wta ever returns.
1217 In some cases, the code is fine, but GCC isn't smart enough to
1218 figure that out; this usually happens when one variable is only
1219 initialized and used when a particular condition holds true, and
1220 we know that condition will never change within a given invocation
1221 of the function. In this case, we simply initialize the variables
1222 to placate the compiler, hopefully to a value which will cause a
1223 crash if it is ever actually used.
1224 * print.c (scm_iprin1): Initialize mw_pos.
1225 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
1226 * throw.c (scm_ithrow): Initialize dynpair.
1227 * unif.c (scm_uniform_vector_ref): Initialize cra.
1228 * struct.c (init_struct): Initialize prot.
1229 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
1231 * strports.c (scm_eval_0str): Don't return uninitialized garbage
1232 if EXPR contains no expressions.
1234 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
1236 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
1237 cause an infinite loop (???). So much for the algebraic
1238 equivalency of variable-sized arrays and alloca...
1240 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
1242 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
1243 a SCM boolean, not a C boolean.
1245 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
1247 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
1248 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
1249 rules for raising scm_mtrigger. Previously, unfortunate but not
1250 unlikely circumstances could result in almost constant invokation
1251 of the gc. Now, this situations should be less likely, but they
1252 are not prevented completely.
1254 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
1256 * numbers.c (scm_fuck): Procedure removed; looks like old test
1258 * numbers.h: Prototype removed.
1260 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
1262 * debug.h (scm_debug_frame): Change `vect' member from an in-line
1263 array to a pointer, to match my Nov 21 change in eval.c.
1265 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1267 * libguile.h: Added #include "libguile/backtrace.h", #include
1268 "libguile/stacks.h".
1270 * strings.c (scm_string scm_make_string scm_string_ref
1271 scm_string_set_x scm_string_equal_p scm_string_append):
1272 Bugfix according to scm patch from Aubrey Jaffer:
1273 Corrected long-standing
1274 (not (eqv? (integer->char 128)
1275 (string-ref (make-string 1 (integer->char 128)) 0)))
1276 bug found by John Kozak <jk@noontide.demon.co.uk>.
1278 * strports.c, strports.h: Make scm_eval_0str return the value of
1279 the last expression evaluated (previously, it returned void).
1281 * strports.c, strports.h: New function: scm_read_0str. Does what
1284 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1286 * simpos.c (scm_getenv): return #f if string can't be found in the
1287 environment instead of throwing an exception, for compatibility
1288 with numerous other systems.
1290 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
1292 * Makefile.am (.c.x): Use guile-snarf.
1293 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
1295 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
1297 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1299 * backtrace.c (scm_display_error_message): Made non-static, and
1300 renamed from display_error_message.
1301 * backtrace.h (scm_display_error_message): Added extern decl.
1302 * throw.c (uncaught_throw): Use it to display the error message.
1304 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
1306 * inet_aton.c: Use #if 0, not #ifdef 0.
1308 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
1310 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
1311 to convert the returned value.
1312 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
1313 the offset argument.
1315 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1317 Add new interface to catch/throw, usable from C as well as
1319 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
1320 (scm_internal_catch): New function, replaces...
1321 (scm_catch_apply): Deleted.
1322 * throw.c (scm_catch_apply): Deleted; replaced with a more general
1323 mechanism which is a bit more code, but can be used nicely from C
1324 and implement the Scheme semantics as well.
1325 (scm_internal_catch): This is the replacement; it's named after
1326 the analogous function in Emacs.
1327 (scm_catch): Reimplemented in terms of the above.
1328 (struct catch_body_data, catch_body, catch_handler): New
1329 functions, used by scm_catch.
1330 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
1331 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
1332 support for new cwdr.
1334 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
1337 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
1339 * acconfig.h: Added DYNAMIC_LINKING symbol.
1340 * configure.in: Add option and checks for dynamic linking.
1341 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
1342 dynl.h: New files for dynamic linking support.
1343 * Makefile.am (libguile_a_SOURCES):
1345 (modinclude_HEADERS): Added "dynl.h".
1346 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
1348 * init.c (scm_boot_guile_1): Call
1349 scm_init_dynamic_linking to initialize dynamic linking support.
1351 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
1353 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
1354 (as we Schemers say). It needs to be global, so that I can tweak
1355 it for the proper operation of unexec.
1356 (scm_boot_guile_1_live): New variable, see above.
1358 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
1360 * guile-snarf.sh: Removed.
1361 * PLUGIN/guile.libs: Added dependency for -lm.
1362 * acinclude.m4: Renamed from aclocal.m4.
1363 * PLUGIN/greet: Removed.
1364 * Makefile.am, aclocal.m4: New files.
1365 * configure.in: Updated for Automake.
1367 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
1369 * eval.c (scm_definedp): Use top_level_lookup_closure_var
1370 and not top_level_lookup_thunk_var.
1372 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
1374 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
1376 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
1378 * eval.c (scm_definedp): Incompatibly changed to be a builtin
1379 Scheme function, instead of syntax. Single argument is now a
1382 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1384 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
1385 scm_ra_divide): Properly terminate statements passed as arguments
1386 to IVDEP macros. (Thanks to Bernard Urban.)
1388 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
1389 with non-constant sizes. (Thanks to Bernard Urban.)
1391 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1393 It's an "eval closure", not an "eval thunk." A thunk is a
1394 function of no arguments.
1395 * root.h (struct scm_root_state): Renamed
1396 top_level_lookup_closure_var from top_level_lookup_thunk_var.
1397 (scm_top_level_lookup_closure_var): Renamed from
1398 scm_top_level_lookup_thunk_var.
1399 * root.c (mark_root): Uses changed.
1400 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
1401 * init.c (scm_start_stack): Uses changed.
1402 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
1403 Change scheme-visible name to *top-level-lookup-closure* from
1404 *top-level-lookup-thunk*.
1406 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
1408 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
1409 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
1411 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
1413 * gc.c (struct scm_heap_seg_data): Doc fixes.
1415 * gc.c (scm_gc_sweep): Empty all segments' freelists before
1416 sweeping. Then, prepend each segment's free cells to its
1417 freelist, rather than wiping out the old value. (Thanks to Marius
1420 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
1421 scm_check_freelist, scm_debug_newcell): New functions and
1422 variables, for debugging freelist problems.
1423 * pairs.h (SCM_NEWCELL): New debugging version added.
1424 * gc.h (scm_debug_newcell): Added extern declaration, used by
1425 debugging version of SCM_NEWCELL.
1427 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1429 On some systems <libc.h> conflicts with <unistd.h>, and should not
1430 be #included at all.
1431 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
1432 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
1433 * configure.in: Call it.
1434 * posix.c, filesys.c: Use its results to decide whether or not to
1436 * configure, scmconfig.h.in: Rebuilt with autoconf and
1439 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1441 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
1442 pointer to the stdio stream before calling scm_setbuf0, so the
1443 latter will be able to retrieve it. I'm surprised this didn't
1444 segfault earlier. (Thanks to Christopher Lee.)
1446 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1448 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
1451 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1453 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
1454 number of stack narrowing specifier pairs. The first specifier in
1455 a pair controls inner border, the second the outer border. A
1456 number means cut that number of frames, a procedure object means
1457 cut until that object is found in operator position in a frame.
1459 * root.c (cwdr): Bugfix.
1461 * read.c: Recording of positions disabled by default.
1463 * procs.c (scm_closure_p): New function.
1465 * posix.c (scm_tmpnam): New function.
1467 * load.c: Added #include "throw.h".
1468 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
1471 * load.c, load.h (scm_read_and_eval_x): New function.
1473 * eval.c: Renamed debug option "deval" to "debug".
1475 (scm_eval_x): `eval!' is no longer accessible from the scheme
1476 level. Motivation: We can't allow operations which introduce
1477 glocs into the scheme level. Guile's type system can't handle
1478 these as data. Use `eval' or `read-and-eval!' as replacement.
1480 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
1481 SCM_CONSP since this is a macro!; Set vframe.prev to
1482 scm_last_debug_frame instead of 0. In this way we can look
1483 "above" the virtual start stack frame if we wish.
1484 (scm_debug_hang): New function: Useful for debugging Guile in
1485 certain tricky situations. Will probably be removed later...
1487 * debug.h: Changed semantics of debug option "backtrace". This
1488 option now only indicates whether we want automatic backtrace at
1491 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1493 * ports.c: #include "filesys.h"
1494 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
1496 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
1497 Motivation: This is system specific code which is related to file
1498 I/O. It also may use select. Added code by Gary Houston to
1499 detect presence of character in stdio buffers.
1501 * libguile.h: #include "libguile/libpath.h"
1503 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
1504 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
1505 SCM_SITE_DIR; Install libpath.h among the other include files.
1507 * load.c, load.h (scm_sys_package_data_dir): New function.
1509 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1511 * stacks.h: Bugfix: Don't use tail-array length field as stack
1512 length field! This screwed GC.
1514 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1516 * _scm.h: Added #ifndef around definition of macros min and max.
1518 * __scm.h: Added hooks for threads to plugin to in ints protection
1519 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
1520 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
1521 the main code in these macros duplicated and spread over multiple
1522 files. Renamed SCM_THREADS_SWITCHING_CODE ->
1523 SCM_THREAD_SWITCHING_CODE.
1525 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
1527 * snarf.h: New file.
1528 * guile-snarf.sh: New file.
1529 * Makefile.in (inner_h_files): Added snarf.h
1530 (ancillary, install, uninstall, distclean): Added actions for
1532 (.c.x): Use guile-snarf.
1533 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
1534 (gen_c_files): Note that these depend on guile-snarf.
1535 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
1536 now in "snarf.h". Added #include "snarf.h" to get them.
1537 * libguile.h: Added #include "snarf.h".
1538 (Patches applied and tweaked by Jim Blandy.)
1540 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1542 * socket.c: Use K&R style declaration for 'close'; the GNU coding
1543 standards suggest against providing prototypes for system
1544 functions. Thanks to Greg Troxel.
1546 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1548 * strports.c (scm_eval_0str): New function.
1549 #include "read.h", to get prototype for scm_read.
1550 * Makefile.in (strports.o): Update dependencies.
1551 * strports.h: New prototype.
1553 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
1554 scheme name from "int?" to "integer?". It seems to do the job.
1555 * numbers.h: Rename prototype too.
1556 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
1559 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
1560 scm_num_eq_p): Rename these according to R4RS conventions: call
1561 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
1562 to making libguile R4RS compliant without ice-9...
1564 * load.c (scm_sys_search_load_path): Search for files under all
1565 extensions listed in the %load-extensions variable. If FILENAME
1566 is absolute, return it unchanged, without searching the load path.
1567 (scm_loc_load_extensions): New variable, pointing to
1568 %load-extensions' value cell.
1569 (scm_init_load): Initialize it, and the value it points to.
1570 (scm_primitive_load_path): Improve error reporting.
1572 * load.c (scm_loc_load_hook): New variable, pointing to value cell
1573 of new Scheme variable %load-hook.
1574 (scm_primitive_load): Apply %load-hook to filename.
1576 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
1578 * configure.in: add tests for figuring out whether buffered data
1579 is available in a FILE structure, which is needed by char-ready.
1581 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
1584 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
1585 exceptions using misc_error instead of syserror. It seems a bit
1586 odd to throw an exception if a string can't be found in the
1587 environment, but it's consistent with open-file, stat etc.
1588 (simpos.h): remove sys_ from getenv.
1590 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
1591 occurs, throw an error instead of returning errno. Return value
1593 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1595 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1597 * filesys.c (scm_stat2scm): derive file type and permissions from
1598 the stat mode and append them to the returned vector.
1599 There isn't much overhead in doing this and it avoids the need to
1600 work with S_IRUSR et al. in Scheme.
1601 Define symbols scm_sym_regular etc.
1602 (scm_init_filesys): don't intern S_IRUSR etc.
1604 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1605 and s_primitive_load_path.
1607 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1609 * error.h: don't declare error symbols. prototype for scm_misc_error.
1611 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1614 * error.c: use SCM_SYMBOL to set up error keys.
1615 scm_misc_error: new procedure.
1617 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1619 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1620 between `#!' and `!#' is ignored.
1621 (skip_scsh_block_comment): New function.
1623 * feature.c (scm_set_program_arguments): New argument, FIRST.
1624 * feature.h: Update prototype.
1625 * init.c (scm_boot_guile_1): Pass new argument to
1626 scm_set_program_arguments.
1628 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1630 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1631 (scm_boot_guile): Call scm_set_program_arguments here, later than
1632 the old initialization.
1634 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1635 initialization procedure.
1636 - Delete in, out, err arguments; there are other perfectly good
1637 ways to override these when desired.
1638 - Delete result argument; this function shouldn't ever return.
1639 - Rename init_func argument to main_func, for less confusion.
1640 - Delete boot_cmd argument; main_func is more general.
1641 -Add 'closure' argument, to help people pass data to main_func
1642 without resorting to global variables.
1643 - Abort if reentered; don't bother returning an error code.
1644 - Call scm_init_standard_ports to set up the default/current
1645 standard ports; no need to pass them to scm_start_stack.
1646 - Remove code to evaluate the boot_cmd, and start the repl; let
1647 the user do something like that in main_func if they want.
1648 - Remove code to package up a return value; main_func can do any
1650 - Call exit (0), instead of returning.
1651 (scm_start_stack): Don't initialize the I/O ports here; that's
1652 weird. Delete in, out, err arguments. Move guts to
1653 scm_init_standard_ports, scm_stdio_to_port.
1654 (scm_init_standard_ports): New function, to set up current and
1655 default standard ports.
1656 (scm_start_stack, scm_restart_stack): Make these static.
1657 * init.h (scm_boot_guile): Adjust declaration.
1658 (scm_start_stack, scm_restart_stack): Remove externally
1659 visible declarations for these.
1660 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1662 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1663 written out several times in scm_start_stack.
1664 * fports.h: New declaration for the above.
1666 * feature.c (scm_set_program_arguments): New function.
1667 * feature.h: New declaration for the above.
1669 * ports.c: Formatting tweak.
1671 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1673 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1674 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1675 for obtaining the address of a car or cdr field. Motivation:
1676 &SCM_CXR make assumptions about the internal structure of the
1679 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1680 Motivation: see SCM_CXRLOC.
1682 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1683 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1684 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1685 Motivation: Safer use. Some other macros are defined in terms of
1686 these operations. If these are defined using the SCM_SETCXR
1687 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1688 to inefficiency and an <e1> with side-effects could potentially
1689 break. Also, these particular operations are heavily utilized in
1690 the garbage collector. In unoptimized code there will be a
1693 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1694 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
1695 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
1696 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
1697 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
1698 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1699 vports.c: Cleaned up use of pairs: Don't make any special
1700 assumptions about the internal structure of selectors and
1701 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1702 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1703 (Among other things, this change makes it easier to build Guile
1704 with certain compilers which have problems with casted lvalues.)
1706 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1708 * stacks.c: Improve selection of relevant stack frames when making
1709 a stack object. Introduce one level of indirection in the stack
1710 object to make it possible to "narrow" to a certain region of the
1711 stack. This facilitates making use of more clever algorithms (not
1712 implemented) for selecting relevant frames and gives a cleaner
1713 design since selection of frames can be done independently of
1714 extraction of frames from the real stack.
1715 (scm_stack_id): Also take #t as argument which means look at
1718 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1719 Turn n_tail into an integer directly representing current number
1720 of frames in stack. Add field tail.
1722 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1724 * debug.c (scm_make_memoized): Made it available at scheme level.
1725 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1726 SCM_NIMP before applying heavier predicates in argument checking.
1727 (scm_local_eval): Also take memoized object as argument.
1729 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1730 aren't created with zero length, but should such a strange
1731 creature suddenly turn up...
1733 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1735 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1736 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1738 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1740 * variable.c (scm_make_variable): Make the name hint optional, as
1742 (anonymous_variable_sym): Renamed from variable_sym. All uses
1745 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1746 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1747 of scm_primitive_load_path was also changed to
1748 "primitive-load-path", from "%try-load-path". Callers changed.
1749 We'd like to respect the convention that a function named
1750 "try-mumble" should behave just like the function called "mumble",
1751 but return #f instead of signalling some error.
1752 * load.h: Rename prototypes.
1754 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1756 * print.c (make_print_state, grow_print_state), print.h: Modified
1757 the print state representation: Don't use a tail array for
1758 recording of circular references. Resizing of the print state
1759 structure invalidates the print state pointer. To avoid passing
1760 around an indirect print state reference to all printing
1761 functions, we instead let the print state reference a resizable
1764 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1766 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1767 Don't crash when passed an improper list terminated by a
1768 non-immediate value.
1770 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1772 Allocate data for structures on an eight-byte boundary, as
1773 required by the tagging system.
1774 * struct.c (alloc_struct): New function.
1775 (scm_make_struct, scm_make_vtable_vtable): Call it.
1776 * struct.h (scm_struct_n_extra_words): Bump to 3.
1777 (scm_struct_i_ptr): New "field".
1778 * gc.c (scm_gc_sweep): When we need to free the data, use the
1779 information stored by alloc_struct to find the beginning of the
1780 block allocated to the structure, so we can free it.
1782 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1784 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1787 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1788 (scm_debug_info): New member: id.
1790 * stacks.c: Stacks are now represented as structs; Stacks have an
1791 id given to them by `start-stack'.
1792 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1794 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1795 Changed stack representation.
1797 * debug.c (scm_procedure_name): Try procedure property `name' for
1798 compiled closures aswell.
1800 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
1802 * eval.c: scm_i_name moved to gsubr.c
1803 (scm_m_define): Record names of all kinds of procedure
1804 objects. (Earlier, only closures were recorded.)
1806 * procprop.h: Added declaration of scm_i_name.
1808 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1809 (scm_make_gsubr): Record names of compiled closures.
1811 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1813 * debug.c, debug.h: Removed obsolete code.
1815 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1816 stacks.c: Renamed regs --> scm_contregs.
1818 * print.c (scm_free_print_state): Cleanup print state before
1819 returning it to pool. It is better to do it here than in
1820 scm_prin1 since scm_prin1 is called often.
1822 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1823 s_set_source_property_x): Check that first argument is a pair or a
1826 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1827 scm_i_line, scm_i_column and scm_i_breakpoint global.
1829 * init.c: Added #include "backtrace.h" and #include "stacks.h".
1830 (scm_boot_guile_1): Added calls to scm_init_backtrace and
1833 * debug.h: Added debug object smob declaration and macro
1836 * configure.in: Build with backtrace.o and stacks.o if debug
1839 * Makefile.in: Added entries for new files: backtrace.c,
1840 backtrace.h, stacks.c and stacks.h.
1842 * symbols.c (scm_sym2ovcell): Fixed documentation.
1844 * _scm.h (min, max): Added.
1846 * async.c: Moved `min' macro to _scm.h.
1848 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1849 SCM_BACKTRACE_INDENT.
1851 * eval.c: Added new debug options `maxdepth' and `indent'.
1853 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
1855 * print.h: Added selector SCM_PRINT_STATE.
1857 * print.c: New functions: scm_make_print_state,
1858 scm_free_print_state.
1860 * print.h: Added declarations for scm_make_print_state,
1861 scm_free_print_state.
1863 * debug.c (scm_m_start_stack): New acro.
1865 * debug.h: Small cleanup.
1867 * init.c (scm_boot_guile_1): Moved scm_init_debug below
1870 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

1895 More prototype-related changes from Marius Vollmer:
1896 * gdb_interface.h: Wrapped header file in #ifdef/#endif
1897 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
1898 * ports.h (ptobfuns): Added prototypes. This means some casting in
1900 * fports.c: Added casts for initializations, since the functions
1901 are defined to take FILE * as their stream argument, not SCM.
1902 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
1903 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
1904 to `char *str_data' to conform to prototype.
1906 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1908 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
1910 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
1912 * stime.c, stime.h: use SCM_P method.
1914 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1916 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
1917 be given at least two arguments. Insist that lst's last element
1918 be a list, but don't make any requirements of its predecessors.
1920 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1922 * eval.c (scm_nconc2last): Revert last change; there seems to be
1923 other stuff going on here.
1925 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1927 * eval.c (scm_nconc2last): Make sure that each element of lst
1928 (which is a list of argument lists, except for the tail) is a
1929 proper list, i.e., finite and terminated by '().
1931 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1933 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
1936 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
1937 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
1940 * vectors.c (scm_make_vector): Fill vectors with the undefined
1941 value, to help make Guile Scheme code more portable to other
1944 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
1945 * symbols.h, tags.h: Doc fixes.
1947 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
1949 * async.c (scm_take_signal): Doc fixes.
1951 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
1953 * numbers.c (scm_divbigint): When the remainder is zero, we don't
1954 want to subtract it from the modulus; we just want to leave it
1957 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
1959 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
1962 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
1964 * throw.c (scm_catch_apply): Finished implementation of
1967 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
1969 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
1971 (scm_init_filesys): set "i/o-extensions" feature.
1974 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
1976 * Makefile.in (root.o): Correct dependencies.
1978 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
1980 * Makefile.in: Added dependency entry for root.o.
1982 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
1983 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
1985 * init.c (scm_start_stack): Set initial root continuation number
1988 * procs.c: New function: scm_thunk_p.
1990 * procs.h: Added declarations of scm_thunk_p.
1992 * root.c: Renamed `call-with-new-root' -->
1993 `call-with-dynamic-root'.
1994 (cwdr): Removed allocation of new root state. This should be done
1995 separately by use of scm_make_root.
1996 (scm_apply_with_dynamic_root): New function: Does what it
1997 sounds like. Needed when spawning threads.
1999 * root.h: Added member last_debug_frame to root state.
2000 Added #include "libguile/debug.h"
2002 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
2003 arguments. The motivation is that code in root.c needs catch
2004 functionality, and we want to avoid code duplication.
2005 New functions: scm_catch, scm_lazy_catch. These are wrappers for
2006 scm_catch_apply. scm_lazy_catch is intended to introduce catch
2007 handlers that run without popping the stack into the dynwind
2010 * throw.h: Added prototypes for scm_catch_apply and
2013 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2015 * root.h (scm_root, scm_set_root): Decouple thread support details
2016 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
2017 SCM_SET_THREAD_LOCAL_DATA.
2019 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
2020 and tortoise scanning loop.
2022 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
2024 * Makefile.in: Rebuild dependencies.
2026 * libguile.h: #include "libguile/print.h" before "smob.h", since
2027 the latter uses the print_state structure.
2029 * throw.c (scm_ithrow): Use the correct variable when checking to
2030 see if a given element of scm_dynwinds is a valid catch.
2032 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
2033 structure, abort; don't just silently ignore the garbage.
2035 * _scm.h: #include "print.h" here, since it seems to be used just
2037 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
2038 strports.c, unif.h: Don't #include "print.h".
2040 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2042 * feature.h (scm_loc_features): Removed external declaration.
2043 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
2045 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2047 * feature.c (scm_init_feature): Added threads feature (needs to be
2048 initialized here, since features doesn't exist when
2049 scm_init_threads is called).
2051 * libguile.h: Added #include "libguile/../threads/threads.h".
2052 (This is a kludge to get thread support working. This should be
2055 * configure.in, acconfig.h: Added flags for thread support.
2057 * scmsigs.c: Define `signal' to be `pthread_signal' if using
2060 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
2061 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
2064 * _scm.h: Added conditional #include "threads.h"
2066 * __scm.h (SCM_ASYNC_TICK): Added call to macro
2067 SCM_THREADS_SWITCHING_CODE.
2069 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
2070 allocate the basic dynamic root object.
2071 (scm_boot_guile): Added call to scm_init_root.
2073 * root.c, root.h: Added root smob.
2074 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
2075 functions: Implements dynamic roots mostly according to spec in
2076 SCM manual. Main difference is that the second argument is a
2077 throw handler rather than an error "thunk".
2079 * root.h: Added declaration of scm_init_root.
2081 * root.c: Added #include "genio.h", #include "smob.h", #include
2082 "pairs.h", #include "throw.h", #include "dynwind.h", #include
2084 (scm_init_root): Added #include "root.x".
2086 * throw.c: Added #include "stackchk.h"
2087 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
2088 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
2089 can be used in scm_call_with_new_root; Added reenabling of stack
2090 checking when catching a throw.
2092 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
2094 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
2096 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
2097 element is not found, as per R4RS.
2099 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2101 * list.c: Doc fixes throughout.
2103 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2105 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
2106 declare the char * to be const. Avoids a warning in rgx.c.
2108 * ports.h: spelling fix.
2110 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
2113 * load.c (scm_sys_try_load_path): throw an error if file not found
2114 (like it says it in NEWS).
2116 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2118 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
2119 PROPS slot to '(), not #f; it's an empty alist.
2121 * throw.h, throw.c: Use SCM_P instead of #if hair.
2123 Remove special support for uncaught throws; see throw.c for
2125 * throw.c (uncaught_throw): New function.
2126 (scm_ithrow): Call uncaught_throw if we don't find a throw
2127 target; don't mess with scm_bad_throw_vcell.
2128 (scm_bad_throw_vcell): Variable deleted.
2129 (scm_init_throw): Don't initialize it.
2131 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
2134 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2136 * numbers.c (scm_istr2int): If the number is short (as most
2137 numbers are), just call scm_small_istr2int to deal with it.
2138 (scm_small_istr2int): New function, created by un-#ifdefing the
2139 non-bignum version of scm_istr2int and renaming it.
2141 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
2143 * load.c (scm_sys_try_load): don't check whether value returned
2144 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
2145 Change the Scheme name from %try-load to primitive-load.
2147 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
2148 Can avoid passing a message, allowing it to be derived in the
2149 error handler (e.g., if we want to throw to the key both from
2152 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
2154 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
2155 references now have a new appearance which is more compact and
2156 also gives a clue about what the target of the reference is.
2157 By setting parameters in the print state, more fancy printing can
2158 be achieved. This is used by the (not yet commited) backtrace
2161 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
2163 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
2166 * print.c: Added #include "struct.h". Removed function
2169 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
2170 scm_iprin1. Removed prototype for scm_prlist.
2172 * arbiters.c (prinarb),
2173 async.c (print_async),
2174 debug.c (prindebugobj, prinmemoized),
2175 eval.c (prinprom, prinmacro),
2176 filesys.c (scm_fd_print, scm_dir_print),
2178 mallocs.c (prinmalloc),
2179 numbers.c, numbers.h (scm_floprint, scm_bigprint),
2180 smob.h (scm_smobfuns),
2181 srcprop.c (prinsrcprops),
2183 unif.c, unif.h (scm_raprin1, rapr1),
2184 variable.c (prin_var): Changed argument `int writing' to
2185 `scm_print_state *pstate'.
2187 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
2188 that it will be called before scm_init_print.
2190 * print.c (scm_prin1): Print states are now allocated when calling
2191 scm_prin1 and then passed around to all printing functions as an
2192 argument. A cache `print_state_pool' enables reuse of print
2194 (scm_make_print_state): New function.
2195 (scm_iprin1): Adaption to print states.
2196 (scm_iprlist): An initial "hare and tortoise" scan brings down
2197 time complexity to O (depth * N). (Better time complexity will be
2198 achieved when the printing code is completely rewritten.)
2200 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2202 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
2203 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
2204 it gets done whether or not the cache variable has a value.
2206 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2208 Distinguish #f and ().
2209 * __scm.h: #undef SICP.
2210 * pairs.h (SCM_EOL): Delete this definition, equating it with
2212 * tags.h (SCM_EOL): Give it a new definition here; I think I found
2213 the value it used to have. Doc fixes, too.
2215 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
2217 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
2218 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
2219 Lord's implementation of structs, allowing for tail arrays as
2220 described in the manual. Also fixed some bugs. (Both the interface
2221 and the implementation should be improved.)
2223 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
2225 * print.c, print.h: Closures now print like #<procedure foo (x)>.
2226 People who whish to see the source can do `(print-enable 'source)'.
2227 Removed #ifdef DEBUG_EXTENSIONS.
2229 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2231 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
2232 integer (assuming for now accepting an integer is a good thing).
2234 * error.c, fports.c: replace use of %S in lgh_error args with %s.
2235 %S will be used instead for write'ing arguments.
2237 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
2238 asserts. fix a few other asserts.
2239 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
2240 scm_uniform_vector_ref, scm_array_set_x,
2241 scm_dimensions_to_unform_array): change args in
2242 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
2243 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
2244 scm_substring_fill_x): likewise.
2245 gsubr.c (scm_gsubr_apply): likewise.
2246 eval.c (SCM_APPLY): likewise.
2248 * eval.c (4 places): replace scm_everr with lgh_error or
2251 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
2252 scm_memory_error): new procedures.
2253 scm_everr: deleted. can use scm_wta, dropping first two args.
2254 scm_error: convert NULL subr to SCM_BOOL_F.
2256 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
2259 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
2262 * error.c, error.h: new error keys: scm_arg_type_key,
2263 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
2265 scm_wta: reimplement using lgh_error instead of scm_everr.
2267 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
2269 * gdbint.c: scm_lread now has one more argument.
2271 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
2272 scm_port_\1; Added mutator scm_set_port_filename_x (used when
2273 loading source from non-file ports, which, e. g., happens when
2274 using the Emacs interface).
2276 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
2279 * read.c: Added code for recording of positions of source code
2280 expressions; New functions: recsexpr, scm_lreadrecparen;
2281 _scm_make_srcprops --> scm_make_srcprops
2282 (scm_flush_ws): Removed updating of positions counters. This work
2283 is already done by scm_gen_getc
2285 * read.h: Added prototype for scm_lreadrecparen
2287 * print.c: Added #include "alist.h"
2289 * eval.c: Added #include "hash.h"
2291 * eq.c: Added #include "ramap.h"

2297 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
2298 --> scm_make_srcprops
2300 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
2301 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
2302 function calls in the definition of the whash access macros.
2304 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
2306 * init.c (scm_boot_guile): Add level of indirection to
2307 scm_boot_guile_1() to ensure that stack base pointer is properly
2308 initialized. There was no guarantee that variable i was the
2309 highest/lowest variable on stack (i.e. the call frame of
2310 scm_boot_guile was not completely protected from gc).
2312 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
2314 * ports.h (scm_port_table): put back file_name, it will be used to
2315 support debugging. Undo related changes in fports.c, ioext.c,
2318 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2320 * ports.h (scm_port_table): remove file_name member for now, it seems
2322 * fports.c (scm_open_file): don't set file_name in PTAB.
2323 (prinfport): don't use file_name in PTAB.
2324 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
2325 * ports.c (scm_add_to_port_table): don't intialize file_name.
2326 (scm_port_file_name): remove for now.
2327 * gc.c (scm_gc_mark): don't mark PTAB file_name.
2329 * fports.h (scm_mkfile): prototype deleted.
2330 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
2332 * debug.c, unif.c: use scm_out_of_range instead of
2333 wta for range errors (ASSERT still needs work).
2335 * error.c, error.h (scm_out_of_range): new procedure.
2337 * error.c, error.h (scm_out_of_range_key): new key.
2339 * posix.c (scm_sync): #else was missing.
2341 * error.c, error.h: append _key to names scm_num_overflow and
2344 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
2345 of consing an empty list.
2346 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
2347 of macros, saves code and string space.
2348 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
2349 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
2350 lower case. Rename scm_syserror_m to scm_syserror_msg.
2351 error.h: prototypes for new procedures.
2353 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
2355 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
2357 * error.c, error.h: setup scm_num_overflow key.
2359 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
2360 Remove definition of SCM_OVSCM_FLOW.
2362 * fports.c (scm_open_file): use SCM_SYSERROR_M.
2364 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
2365 explicit message and args.
2367 * error.c, error.h, __scm.h: change system_error_sym to
2370 * error.c (system_error_sym): remove leading %% from the Scheme name
2373 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
2375 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2377 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
2378 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
2379 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
2380 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
2381 renamed. (These were introduced by unsupervised name
2384 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2386 * print.c: Added code for detection of circular references during
2387 printing. (init_ref_stack, grow_ref_stack): New functions. Added
2388 a hook for printing of closures (accessible via print options).
2389 This leads to a split of calls to scm_iprin1 into two classes:
2390 elementary print operations (e. g. the code which prints a smob)
2391 still use scm_iprin1 while top level calls (like scm_display) use
2392 scm_prin1. scm_prin1 begins by clearing the data structure used
2393 to record reference information.
2395 * print.h: Added declarations of scm_prin1 and scm_prlist.
2397 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
2399 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
2401 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
2403 * error.c (err_head): scm_iprin1 --> scm_prin1
2405 * debug.c: Adjusted header comment.
2409 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>

2413 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2415 * gdbint.c (gdb_read): Now possible to run during GC.
2416 (unmark_port, remark_port): New functions.
2418 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
2420 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
2421 of allocating a new string object. Also, increase size by
2422 the factor 2 instead of 1.5.
2424 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
2426 * __scm.h (SCM_P): Corrected to run under traditional C.
2428 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
2431 * async.c: Calls to scm_sysintern corrected.
2433 * async.h (scm_async_clock): Redundant declaration removed.
2435 * continuations.c (scm_dynthrow): Redundant declaration removed.
2437 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
2438 Definition typos corrected.
2440 * debug.h: Missing declarations of functions in debug.c added
2443 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2444 Missing declarations to functions in eval.c added.
2446 * filesys.c: Possibly uninitialized variable rv.
2448 * gc.h (scm_object_addr, scm_unhash_name): Missing
2449 declarations of functions defined in gc.c added.
2451 * genio.c: Possible typos str_data -> wstr_data. ???
2453 * genio.c: Possibly unintended shadowing of local variable
2454 `int c' (gotos out of scope of inner `c'). ???
2456 * init.c: Uninitialized `SCM last' may be used.
2458 * ioext.h: (scm_sys_isatty_p): Typo.
2460 * list.h (scm_list_head): Missing prototype for function in
2463 * numbers.c (scm_two_doubles): Changed from extern to static
2464 (is used only within numbers.c).
2466 * numbers.h: Repeated declarations removed.
2468 * ports.h (scm_close_all_ports_except): Declaration for the
2469 function defined in ports.c added.
2471 * posix.h: Missing declarations added.
2473 * procs.h (scm_make_subr_opt): Missing declaration added.
2475 * socket.h (scm_sys_gethost): Missing declaration added.
2477 * socket.h: Redundant declarations removed (they are in fdsocket.h).
2479 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
2480 Missing declarations added.
2482 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
2484 * struct.c: Uninitialized variable `SCM answer' may be used.
2486 * unif.c (l2ra): Declaration prototype.
2488 * unif.c (scm_array_equal_p): Dummy definition removed (it is
2489 defined in ramap.c).
2491 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
2492 Redundant declarations removed (they are in ramap.h).
2494 * variable.h (scm_make_udvariable,
2495 scm_make_undefined_variable): Declaration corrected to
2496 correspond variable.c.
2498 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
2499 Missing declarations added.
2501 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
2503 * Makefile.in (distclean): Don't forget to delete fd.h.
2505 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2507 * fd.h.in, tags.h: Trivial cleanups.
2509 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
2510 marksweep.h just declared functions from gc.c.
2511 * gc.h, libguile.h: Don't #include "marksweep.h".
2512 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2513 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
2514 dependencies updated.
2516 * libguile.h: Don't #include "files.h"; it's been deleted.
2518 * files.c (scm_sys_delete_file): Moved to filesys.c.
2519 File is now empty; deleted.
2521 * filesys.c: scm_sys_delete_file is now here. Remove
2522 #if's; they seem to rely on remnants of an old portability
2523 regimen. If the problems come up again, solve them properly,
2524 using autoconf. Specifically: Don't test M_SYSV, and #define
2525 remove to be unlink if it's #defined; don't use remove just
2526 because HAVE_STDC_HEADERS is #defined.
2527 * filesys.h: Add declarations for scm_sys_delete_file.
2528 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2529 files.o, files.h, files.c, and files.x.
2530 * init.c: Don't #include "files.h", and don't call scm_init_files.
2532 Use SCM_P instead of PROTO; the latter intrudes on the user's
2534 * params.h: Deleted; definition of SCM_P moved to...
2535 * __scm.h: ... here, where it replaces PROTO macro.
2536 * libguile.h, smob.h: Don't #include "params.h".
2537 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
2538 smob.h: Fix prototypes accordingly.
2539 * Makefile.in: Update dependencies.
2540 (inner_h_files): Remove params.h.
2542 * gc.c: #include "gc.h"; every module should include its header,
2543 to let the compiler cross-check the declarations against the
2546 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2547 simpos.h: #include "libguile/__scm.h".
2549 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2551 * init.c: Don't forget to #include smob.h and init.h.
2552 * Makefile.in: Dependencies updated.
2554 * smob.h: Use PROTO instead of #if __STDC__.
2556 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2558 * __scm.h: Doc fixes.
2560 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2561 <angles>; this allows `make depends' to work properly.
2563 * libguile.h: #include smob.h and pairs.h before the others; they
2564 define typedefs used by other headers.
2566 C files should #include only the header files they need, not
2567 libguile.h (which #includes all the header files); the pointless
2568 recompilation was wasting my time.
2569 * Makefile.in (all .o dependency lists): Regenerated.
2570 * libguile.h: Don't try to get a definition for size_t here...
2571 * __scm.h: Do it here.
2572 * _scm.h: Since this is the internal libguile header, put things
2573 here that all (or a majority) of the libguile files will want.
2574 Don't #include <libguile.h> here; that generates dependencies on
2575 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2576 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2577 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

2674 * weaks.c: Get "weaks.h".
2676 * stackchk.h: #include "libguile/debug.h",
2678 * print.h, read.h: #include "options.h", since everyone who uses
2679 either of these files will need that.
2681 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2682 anyone who uses this file will need them to define the smob
2683 printing functions. Also, get markers.h, since people will need
2684 to #define the mark functions.
2686 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2687 * ports.h: ... to here.
2689 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2690 don't rely on archaic C default type rules.
2692 * fports.h: #include "libguile/ports.h", since you need that in
2693 order to parse this.
2695 * genio.h: #include "libguile/print.h", because you need that to
2696 parse this; don't bother #including "ports.h", since print.h gets
2699 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2701 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2702 this; it's now a reference to an element of *scm_root.
2704 * debug.h: Don't #include "options.h"; the compiler won't be able
2705 to find that once the headers are installed; instead, #include
2706 "libguile/options.h".
2707 * gc.h: Same, with marksweep.h.
2708 * mbstrings.h: Same, with symbols.h.
2709 * scmhob.h: Same, with _scm.h.
2710 * smob.h: Same, with params.h.
2712 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2713 C files; there's no need for this, and it forces recompilations
2716 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2718 * error.c (scm_error): declare scm_error_callback.
2720 * error.h: prototype for scm_error_callback.
2722 * __scm.h: define lgh_error.
2723 (SCM_SYSERROR): redefine using lgh_error.
2725 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2727 * error.c (scm_error): new procedure.
2729 * error.h: prototype for scm_error.
2731 * Makefile.in (install): install scmconfig.h from the current
2732 directory, not $(srcdir).
2734 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2736 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2737 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2738 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
2739 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,

2744 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2745 vports.h, weaks.h: #include "libguile/__scm.h", not
2746 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2747 dependencies are within libguile properly.
2749 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2751 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2752 when scmconfig.h doesn't exist.
2754 * load.c (scm_sys_try_load): Correct spelling.
2756 * feature.c (scm_loc_features): Make this static.
2758 * Makefile.in (libpath.h): Omit trailing slash from path. We
2759 shouldn't require it of users, so why put it here?
2761 Move code to initialize and search %load-path from ice-9 to C
2762 code, so we can use the load-path to find the ice-9 boot code;
2763 this makes it easier to run Guile without installing it. See
2764 corresponding changes in guile/Makefile.in.
2765 * feature.c: Move stuff concerned with the load path to load.c.
2766 (scm_compiled_library_path): Deleted.
2767 Don't #include libpath.h here.
2768 * feature.h: Don't mention scm_compiled_library_path.
2769 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2770 <sys/stat.h>, and <unistd.h> (if present).
2771 (R_OK): #define if the system hasn't deigned to.
2772 (scm_loc_load_path): New variable.
2773 (scm_init_load_path, scm_sys_search_load_path,
2774 scm_sys_try_load_path): New functions.
2775 (scm_init_load): Initialize scm_loc_load_path to point to the
2776 value cell of the Scheme %load-path variable.
2777 * load.h: Add declarations for scm_sys_search_load_path,
2778 scm_sys_try_load_path.
2779 * init.c: Call scm_init_load_path.
2780 * Makefile.in (feature.o, load.o): Dependencies updated.
2782 * load.c, load.h: Rewrite using PROTO macro.
2784 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2786 * gc.c (scm_cellp): New function: C predicate to determine if an
2787 SCM value can be regarded as a pointer to a cell on the heap.
2789 * gc.h: Added declaration of scm_cellp.
2791 * gdb_interface.h: New file: The GDB interface header from the GDB
2794 * gdbint.c: New file: GDB interface.
2796 * gdbint.h: New file: GDB interface.
2798 * libguile.h: Added #include <libguile/gdbint.h>.
2800 * init.c (scm_boot_guile): Added scm_init_gdbint.
2802 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2803 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2804 found if object files and source are kept separate).
2806 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2808 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2810 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2812 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2813 TK_SRC_DIR; they're not relevant any more.
2815 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2816 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2818 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2820 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2821 search path, so we can find the <libguile/MUMBLE.h> headers.
2823 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2825 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2826 implicit in the .c.o rule.
2827 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2830 Put the library path in a header file, instead of passing it on
2831 the command line in every compilation.
2832 * Makefile.in (libpath.h): New target.
2833 (feature.o): Depend on libpath.h.
2834 (clean): Delete libpath.h.
2835 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2836 * feature.c: ... #include "libpath.h" here.
2837 * .cvsignore: Ignore libpath.h.
2839 Don't install the unwashed masses of Guile header files in the
2840 main #include path; put most of them in a subdirectory called
2841 'libguile'. This avoids naming conflicts between Guile header
2842 files and system header files (of which there were a few).
2843 * Makefile.in (pkgincludedir): Deleted.
2844 (innerincludedir): New variable; this and $(includedir) are enough.
2845 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
2846 (installed_h_files): Divide this up. Now this variable lists
2847 those header files which should go into $(includedir) (i.e. appear
2848 directly in the #include path), and ...
2849 (inner_h_files): ... this new variable says which files appear in
2850 a subdirectory, and are referred to as <libguile/mumble.h>.
2851 (h_files): List them both.
2852 (install): Create innerincludedir, not pkgincludedir. Put
2853 the installed_h_files and inner_h_files in their proper places.
2854 (uninstall): Corresponding changes.
2855 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2856 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2857 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
2858 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
2859 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
2860 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2861 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2862 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2863 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2864 vports.h, weaks.h: Find __scm.h in its new location.
2865 * __scm.h: Find scmconfig.h and tags.h in their new locations
2866 (they're both "inner" files).
2868 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
2870 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
2872 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2874 * posix.c: Doc fixes.
2876 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
2878 * socket.c: Don't include a prototype for inet_aton; just use a
2879 K&R style declaration, to avoid warnings but minimize the chance
2880 of conflicts with the system.
2882 On NextStep, <utime.h> doesn't define struct utime, unless we
2883 #define _POSIX_SOURCE before #including it.
2884 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
2885 * acconfig.h: New comment text for above CPP symbol.
2886 * configure.in: Call it.
2887 * posix.c: #define _POSIX_SOURCE if it seems necessary.
2889 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
2891 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
2892 testing for __EMX__.
2894 * posix.c: #include <libc.h>, if it exists.
2896 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
2897 don't even know if the latter exists.
2899 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
2900 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
2901 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
2903 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
2905 (scm_init_posix): Use them when initializing the Scheme constants
2908 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2910 * Makefile.in (libdir, includedir, bindir): Use the
2911 autoconf-supplied values, instead of deriving them ourselves.
2912 (pkgincludedir, datadir, pkgdatadir): New variables.
2913 (install, uninstall): Put the header files in a special
2914 subdirectory, not in the main search path.
2916 * Makefile.in (ALL_CFLAGS): Provide the proper value for
2917 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
2919 * Makefile.in (IMPLPATH): Deleted; never used.
2921 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
2922 on the Tcl/Tk source any more.
2923 (INCLUDE_CFLAGS): Remove references to the above.
2925 * Makefile.in (version.o): Corrected dependencies.
2927 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
2929 * libguile.h: #include "version.h"
2931 * init.c (scm_boot_guile): Call scm_init_version.
2932 * gscm.c (gscm_run_scm): Call scm_init_version.
2934 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
2935 GUILE_VERSION): AC_DEFINE these.
2936 (acconfig.h): #undef the above symbols.
2938 * Makefile.in (libobjs): Add version.o.
2939 (installed_h_files): Add version.h.
2940 (c_files): Add version.c.
2941 (gen_c_files): Add version.x.
2942 (version.o): New rule.
2943 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
2944 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
2945 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
2946 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
2947 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
2948 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
2949 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
2950 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
2951 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
2952 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
2953 weaks.o): Add version.h to dependency lists.
2954 (markers.o): Remove duplicate rule.
2956 * version.h: New file.
2958 * version.c: New file.
2960 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2962 * symbols.c (scm_strhash): scm_downcase is now a function, not an
2963 array; use it appropriately. Since GCC is quite happy to
2964 subscript functions, it never warned us about this; we should use
2965 -Wpointer-arith in the future. I guess we never tested
2968 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2970 * socket.c: Doc and copyright fixes.
2972 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2974 * debug.c: Fixed and improved gdb support.
2976 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2978 * socket.c: Added declaration of inet_aton to avoid compiler
2979 warning. (Hope this solution is correct.)
2981 * stime.c: Added declaration of ftime. (This is missing in
2984 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
2986 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2988 * Makefile.in (c_files): add strerror.c.
2990 * strerror.c: new file from Emacs' sysdep.c.
2991 maybe configure should also check for sys_errlist.
2993 * configure.in (AC_REPLACE_FUNCS): add strerror.
2995 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2997 * debug.c (scm_init_debug): Added initialization for
2998 scm_evaluator_traps.
3000 * debug.h, debug.c: Various name changes.
3001 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
3002 "debug-options-interface". See commentary in options.c.
3004 * options.h, options.c: Options now have documentation strings.
3005 Also added a long explanatory commentary.
3007 * eval.c, print.h, print.c, read.h, read.c: Modifications to
3010 * gscm.c, init.c, root.c, throw.c: Bug fixes:
3011 last_debug_info_frame is now updated in all cases.
3013 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
3016 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3018 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
3019 Added option STACK_CHECKING.
3021 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3023 * Makefile.in: Added {debug,options,srcprop}.{h,c}
3025 * __scm.h: Removed symbols for debugging support.
3027 * acconfig.h: Added symbols for debugging support.
3029 * configure.in: Added user option for debugging support.
3030 --enable-debug will include the debugging code into libguile.a.
3032 * continuations.c (scm_make_cont): Enlarged the #if 0 around
3033 scm_relocate_chunk_to_heap.
3035 * debug.c: New file: low-level debugging support. It also
3036 includes support for debugging with gdb. (The extensions to gdb
3037 are written by Per Bothner at Cygnus.)
3039 * debug.h: New file: low-level debugging support.
3041 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
3042 argument pairs. Extensive modifications to the debugging
3043 evaluator. Added "SECTION:" commentaries to clarify what happens
3044 when, during double compilation. Renamed EVALIMP --> EVALIM.
3045 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
3046 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
3047 the beginning of the file. New procedure: scm_unmemocopy.
3048 Added some global state variables needed by the debugging
3049 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
3050 check_entry, check_apply, check_exit, debug_options and
3051 evaluator_traps. New acro: undefine.
3053 * eval.h: Renamed EVAL --> XEVAL.
3055 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
3056 --> scm_make_weak_key_hash_table.
3058 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
3059 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
3061 * libguile.h: Conditionally include debug.h
3063 * objprop.c (scm_object_properties, scm_set_object_properties_x):
3064 scm_object_properties shouldn't return handle. `handle' now gets
3065 initialized in scm_set_object_properties_x. scm_object_properties
3066 doesn't any longer create an entry in scm_object_whash.
3068 * options.c: New file: handling of run time options.
3070 * options.h: New file: handling of run time options.
3072 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
3074 * print.c: New procedure: scm_print_options
3076 * print.h: Defines for print options.
3078 * read.c: New procedure: scm_read_options
3080 * read.h: Defines for reader options.
3082 * root.h: Added scm_source_whash among scm_sys_protects.
3084 * srcprop.c: New file: source properties.
3086 * srcprop.h: New file: source properties.
3088 * throw.c (jbsmob): Jump buffers are now correctly allocated.
3089 (Bug found by A. Green.)
3091 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3093 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3095 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
3097 * libguile.h: #include "objprop.h"; I guess this was forgotten.
3099 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
3100 and should be called by the final client.
3102 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
3104 * gc.h: Use the PROTO macro when declaring functions.
3105 * gc.c: Use the PROTO macro when declaring static functions.
3106 Remove the CPP hair around function definitions.
3108 * gc.c (scm_init_storage): Initialize scm_asyncs.
3110 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
3111 preprocessor symbol; "__scm.h" is where it might get #defined.
3112 * __scm.h: Similar: #include <scmconfig.h> before testing
3115 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
3117 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
3119 * init.c (scm_boot_guile): Add init_func argument; call
3120 (*init_func) instead of calling scm_appinit; it's ucky to
3121 hard-code names for the user's procedures.
3122 * init.h (scm_boot_guile): Adjust declaration.
3124 * __scm.h (PROTO): New macro, for declaring functions with
3127 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
3128 eliminate all the __STDC__ conditionals.
3129 (scm_boot_guile): Add declaration.
3130 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
3131 Remove __STDC__ conditionals around function definitions; the
3132 declarations in init.h will provide the same information, more
3135 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
3136 complain about it in the error message; the error message is
3137 adequate without that note, and there's nothing the user can do
3140 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
3142 * Makefile.in (ancillary): Drop def.sed.
3144 * posix.c (scm_init_posix): Use numeric values, rather than
3145 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
3146 F_OK. The symbols aren't available on some systems, and I'm
3147 pretty sure their values are fixed by common widespread practice.
3148 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
3150 More functions unavailable on some systems.
3151 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
3152 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
3154 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3155 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
3156 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
3157 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
3158 stub that signals an error as the #else.
3160 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
3162 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
3164 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
3166 * unif.c: include ramap.h.
3168 * read.c (endif): case_insensative_p renamed case_insensitive_p.
3170 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
3172 * ports.c: include sys/ioctl.h.
3174 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
3176 * configure.in: check for sys/ioctl.h.
3178 * ports.c: include <malloc.h> not "malloc.h".
3180 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3182 * fports.c: remove ttyname and tmpnam declarations.
3184 * posix.c: fewer ttyname declarations.
3186 * fports.c: include <string.h> not "string.h".
3188 * init.c, ioext.c: include string.h and unistd.h.
3190 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3192 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
3193 genio.c, simpos.c, vports.c: include string.h.
3195 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
3197 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
3199 (scm_addr_buffer_size): change type from scm_sizet to int.
3200 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
3201 from scm_sizet to int.
3203 * error.c: include unistd.h.
3205 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
3208 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
3210 * __scm.hd, def.sed: deleted.
3212 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
3214 Changes for NeXT, suggested by Robert Brown.
3215 * configure.in: Call AC_TYPE_MODE_T.
3216 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
3217 NeXT. Put header file list in alphabetical order.
3218 * configure, scmconfig.h.in: Regenerated.
3219 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
3221 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
3224 * acconfig.h: New file, providing documentation for the CPP
3225 symbols defined in configure.in
3226 * acconfig-1.5.h: Removed; superceded by the above.
3228 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
3230 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
3232 * fports.c (scm_open_file): don't return #f, throw error.
3234 * ioext.c (fileno): renamed from %fileno.
3235 (soft-fileno): deleted.
3237 * ports.c (scm_port_revealed): don't need to check for -1 from
3239 (scm_set_port_revealed_x): return unspecified, not #f.
3241 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
3243 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
3245 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
3247 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
3249 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3251 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
3252 This is necessary on Ultrix, and doesn't hurt portability.
3254 * Makefile.in (dist-dir): New target, implementing a new dist system.
3255 (installed_h_files): Put in alphabetical order.
3256 Remove duplicate entries for markers.h and unif.h.
3257 (c_files): Remove duplicate entries for markers.c.
3258 (ancillary): Renamed from anillery; all uses changed. Remove
3259 PLUGIN; it's a directory, and needs special treatment in dist-dir.
3260 Remove all the ../doc/* files; doc/Makefile.in handles that.
3262 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
3264 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
3265 every if must have an else, or else the whole command has a
3266 non-zero exit code whenever the if's condition is false.
3268 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
3270 * posix.c: include string.h.
3272 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
3274 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
3277 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
3278 Remove leading % from scheme names.
3279 Do not return error values, call SCM_SYSERROR or similar.
3281 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
3283 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
3285 * struct.c (scm_init_struct): new file.
3287 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
3289 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
3290 (scm_list_head): added list-head for rapidly chopping argument
3291 lists off of longer lists (and similar).
3293 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
3295 * objprop.c (scm_object_property): assq the cdr of the whash
3296 handle for obj, not the handle itself.
3298 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
3300 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
3301 weak hash tables last of all marking to avoid an obscure gc bug.
3302 WARNING: circular lists stored in a weak hash table will hose us.
3304 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
3306 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
3307 new functions similar to scm_substring_move_left_x and
3308 scm_substring_move_right_x.
3310 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
3312 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
3315 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
3317 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
3319 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
3321 * strports.c (scm_strprint_obj): convenience function. C for
3322 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
3324 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
3325 removed to a separate library
3327 * init.c (scm_boot_guile): copied from guile-tcl.c.
3328 Initialization specific to tcl interpreters removed.
3330 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
3332 * ports.c (scm_ports_prehistory): size malloced here doesn't
3333 matter so long as it is non-0 (got rid of "* 4").
3335 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
3337 * gscm.h: gscm_mkarray eliminated (presumably was not being used
3338 since its definition was bogus).
3340 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
3342 * mallocs.[ch]: back again (for rx at least).
3344 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
3346 * ports.c: removed functions relating to the mapping between ports
3347 and descriptors. (That stuff is unix-specific and should be collected
3348 in a separate library).
3350 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
3351 (Tom Mckay@avanticorp.com)
3353 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
3355 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
3356 handled correctly (SCM_FREEP was applied to them) -- test for
3357 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
3358 being overwritten with #f. (brown@grettir.bibliotech.com)
3360 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
3362 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
3363 for a specific symbol or for all symbols.
3365 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
3367 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
3368 keys and weak values confused).
3370 Thu Mar 14 22:20:20 1996 Tom Lord <lord@beehive>
3372 * list.c (scm_last_pair): map '()=>'()
3374 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>
3376 * pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:
3377 Generalized assoc and hash-table functions.
3378 Factored pairs.c into multiple files.
3380 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
3382 * gscm.c (gscm_run_scm): got rid of objprop.
