1 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
3 Changes for reduced Guile distribution: one configure script,
5 * configure.in, configure: Removed.
6 * acconfig.h, acinclude.m4: Moved to parent directory, where the
7 real configure script lives.
8 * Makefile.in, scmconfig.h.in: Regenerated.
10 * init.c: #include "script.h", to get prototype for script.c's
13 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
15 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
16 scm_must_malloc, not raw malloc.
18 * script.c (scm_compile_shell_switches): Dyke out debugging output
21 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
23 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
25 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
26 system has them. Hope this is safe. Previously
27 sys/timeb.h was included if HAVE_FTIME was defined or if
28 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
29 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
31 * ioext.c (scm_setfileno): add missing third argument to
34 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
36 * eq.c (scm_equal_p): Correctly compare strings of different
37 varieties. (Thanks to Tim Pierce.)
39 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
41 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
42 #! block comment must occur on a line all by itself.
44 Move most of the guts of shell command processing into libguile,
45 so guile.c can be very small (and eventuallly auto-generated. (I
46 mean, generated mechanically, not self-generated. Hmm.))
47 * guile.c, script.c, script.h: New source files.
48 * init.c (scm_boot_guile_1): Call scm_init_script.
49 * libguile.h: #include "script.h".
50 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
51 targets, for new executable.
52 (libguile_la_SOURCES): Mention script.c.
53 (modinclude_HEADERS): Add script.h.
54 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
55 not dynamic linking is enabled. This is because we're generating
56 executables now. Move CY_AC_WITH_THREADS call after those, so the
57 values of cy_cv_threads_libs captures the libs chosen above.
58 * Makefile.in, configure, aclocal.m4: Regenerated.
60 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
61 We don't maintain this interface any more, and it just confuses
64 * alloca.c: #include <scmconfig.h>, not <config.h>.
65 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
66 it'll get included in disties.
68 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
70 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
71 be distributed, because they confuse people.
72 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
74 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
76 * configure.in: check for presence of gethostent (not present on
78 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
79 * configure, scmconfig.h.in: Regenerated.
81 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
83 * backtrace.c (scm_backtrace): Split message string across
84 newlines properly. GCC is more tolerant of this than other
87 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
89 Merge threads directory into libguile.
90 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
91 threads.h: New source files.
92 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
93 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
95 (modinclude_HEADERS): Add threads.h, coop-defs.h.
96 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
97 coop-threads.c.cygnus, coop-threads.h.cygnus.
98 * configure.in: If we're using threads, include threads.o in
100 * _scm.h, libguile.h: threads.h lives in this directory now.
101 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
102 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
103 currently used, but brought along for information's sake.
104 * ChangeLog-threads: log from old 'threads' directory.
105 * Makefile.in, configure: Rebuilt.
107 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
109 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
112 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
114 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
116 Merge GH interface library into libguile.
117 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
118 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
119 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
120 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
122 (EXTRA_libguile_la_SOURCES): ... here.
123 (pkginclude_HEADERS): Add variable, to get gh.h installed.
124 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
125 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
126 New variables, describing how to build the gh test programs.
127 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
128 build the test programs, and we probably should have been linking
129 libguile.la against them all along, to support AIX shared libs.
130 Add cflags for threads to CFLAGS; add libs for threads to new
131 variable THREAD_LIBS, used in Makefile.am.
132 * ChangeLog-gh: log from old `gh' subdirectory.
133 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
135 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
137 * acconfig.h: Undo change of Apr 9; including the definition of
138 PACKAGE in the guile headers conflicts with applications' own
140 * scmconfig.h.in: Regenerated.
142 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
144 * * filesys.c (scm_fcntl): New function from Roland McGrath.
145 (scm_init_filesys): New symbols for use with fcntl.
146 * filesys.h: Added prototype.
148 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
149 when PROC is receiving no arguments.
151 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
153 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
154 have S_IFSOCK. This is the case under Ultrix.
156 * posix.c (scm_status_exit_val, scm_status_exit_val,
157 scm_status_term_sig, scm_status_stop_sig): Modified to work with
158 Ultrix versions of WIFSTOPPED, etc., which assume that their
159 arguments are lvalues (hmm).
161 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
165 * throw.c: Doc fixes; rearranged.
167 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
169 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
171 * acconfig.h: Added entry for PACKAGE.
172 * scmconfig.h.in: Regenerated.
174 Changes to work with automake-1.1n, which has better libtool support.
175 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
176 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
178 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
180 * Makefile.in: Rebuild.
182 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
184 * stime.c (scm_mktime): take an optional zone argument.
185 (scm_localtime): check putenv return value.
186 (scm_strftime, scm_strptime): moved from posix.c. move #include
188 stime.h, posix.h: update prototypes.
189 (bdtime2c, setzone, restorezone): new static procedures.
190 (scm_mktime, scm_strftime): use them.
191 (scm_strftime): don't call mktime before strftime. Use
192 filltime for return value.
193 (filltime): convert NULL zname to #f.
194 * (scm_strptime): return a count of characters consumed, not
195 the remaining string.
197 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
199 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
200 (scm_mktime): likewise.
202 Uncomment localtime and mktime.
204 * configure.in: add AC_STRUCT_TIMEZONE.
206 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
208 * stime.c (scm_init_stime): don't define ticks/sec.
209 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
210 return value problem and is still portable.)
212 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
214 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
215 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
216 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
217 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
218 cpp_err_symbols.c): Corresponding changes.
219 * Makefile.in: Regenerated.
221 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
223 * posix.c (scm_putenv): don't check HAVE_PUTENV.
224 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
225 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
226 * putenv.c: new file, from sh-utils 1.12.
228 * posix.c (scm_environ): use malloc in place of scm_must_malloc
229 since allocation isn't for Scheme objects.
230 (scm_putenv): copy strings before placing in the environment.
232 * stime.c (scm_current_time): throw an error if time returns -1,
233 instead of returning #f.
234 (scm_get_internal_real_time, scm_get_internal_real_time): use
235 scm_long2num for return value instead of SCM_MAKINUM.
237 * stime.h: prototypes updated.
239 * stime.c (scm_time_in_msec): apparently unused, deleted.
241 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
243 * configure.in: check for gettimeofday.
245 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
246 which may be more usefully portable than a gettimeofday interface.
248 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
250 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
252 * Makefile.in: Regenerated.
254 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
256 * stime.c (filltime): recovered static procedure.
257 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
260 * posix.h: add prototype for scm_close_pipe, remove prototypes for
261 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
263 * * posix.c (scm_mknod): split the mode argument into type and perms
264 arguments, like the extra fields returned by stat.
266 * fports.c (scm_pipob): set the close, free and print procedures.
267 (scm_close_pipe): new procedure.
269 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
270 define them in boot-9.scm
272 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
274 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
275 wan't defined. Don't include fd.h.
277 * Previously fd.h was regenerated whenever configure was run,
278 forcing a couple of files to be recompiled.
280 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
281 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
282 Check for _fileno as well as _file.
284 * ioext.c: don't fd.h.
285 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
288 * Change the stratigy for getting information about errno
289 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
290 generating lists of symbols during the build process, which will
291 not always work, include comprehensive lists in the distribution.
292 To help keep the lists up to date, the "check_signals" and
293 "check_errnos" make targets can be used.
295 * configure.in: don't check for a command to extract errno codes.
296 * Makefile.am: update file lists, remove errnos.list and errnos.c
297 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
298 check_errnos targets.
299 (CLEANFILES): remove errnos.c and errnos.list, add
300 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
301 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
302 * errnos.default: deleted.
303 * cpp_signal.c: new file.
304 * cpp_errno.c: renamed from errnos_get.c.
305 * cpp_err_symbols, cpp_sig_symbols: new files.
306 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
307 * error.c (scm_init_error): #include cpp_err_symbols instead of
309 * posix.c (scm_init_posix): don't intern signal symbols. #include
312 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
314 * strop.c (scm_i_index): allow the lower bound to be equal to the
315 length of the string, so a null string doesn't always give an error.
317 * posix.h: new prototypes.
318 * posix.c (scm_status_exit_val, scm_status_term_sig,
319 scm_status_stop_sig): new functions, as in scsh. They break down
320 process status values as returned by waitpid.
322 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
324 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
325 configure doesn't know about it.
327 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
329 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
331 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
332 which defines C variables with global linkage.
334 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
336 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
339 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
341 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
342 has time to check why this doesn't work well with continuations.
344 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
346 * Fix shell syntax error; some shells won't tolerate
347 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
349 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
351 * posix.c (scm_uname): throw an error if uname fails instead
354 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
356 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
359 * async.c (scm_ints_disabled): definition moved from error.c.
361 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
363 * acconfig.h: Removed PACKAGE.
365 * scmconfig.h.in: Regenerated.
367 * snarf.h: g++ says it's non-portable not to specify the first
368 argument in a varargs declaration. I introduced the first
369 argument by using preprocessor conditionals.
371 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
373 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
374 (scm_freopen): use RO string macros for filename and modes.
375 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
377 * posix.c (scm_getgrgid): simplify conversion of name to C string.
378 (scm_mknod): use RO string macros for path.
380 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
381 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
383 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
384 use SCM_ROSTRINGP and SCM_ROCHARS.
386 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
388 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
391 * ramap.c (scm_ra_matchp, scm_ra_matchp, scm_array_fill_int, racp,
392 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
393 support for byte vectors.
395 * print.c (scm_iprin1): Limit number of vector elements printed
396 according to pstate->length.
398 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
400 * backtrace.c (scm_display_error_message): don't segv if message
403 * error.h: prototype for scm_error_scm.
405 * error.c (scm_error_scm): new procedure, reimplements scm-error
406 in C and uses scm_error.
408 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
410 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
411 pointer to the Scheme variable read-hash-procedures and intern it
412 in scm_init_read. Modify scm_read_hash_extend and
413 scm_get_hash_procedure to use the pointer.
415 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
417 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
418 (SCM_KEYWORD_STYLE): defined.
420 * read.c (scm_read_opts): add a keywords option. This isn't a
421 boolean option, in case someone wants to add support for DSSSL
423 Setup scm_keyword_prefix symbol.
424 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
426 * I've left keyword support disabled by default, since it doesn't
427 seem to break the module system and it gives R4RS standard behaviour.
428 It can be reactivated with (read-set! keywords 'prefix).
430 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
432 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
433 before constructing arbiter.
435 * eval.c (scm_m_define): Bugfix: Check that the object is a
436 closure before setting the procedure property!
438 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
440 * ports.c: Removed `ungetc-char-ready?'.
442 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
444 * read.c (scm_init_read): intitialise scm_read_hash_procedures
445 (idea from Mikael: make it a pair so scm_permanent object only
447 (scm_read_hash_extend): don't call scm_permanent_object.
448 (ideas from Mikael): if chr is already in the list, replace its
449 procedure instead of appending it again. If proc is #f, remove
451 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
453 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
455 * gdbint.c (gdb_read): update scm_lreadr usage.
457 * load.h: update prototypes.
459 * load.c (scm_primitive_load, scm_read_and_eval_x,
460 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
462 * read.h: add prototype for scm_read_hash_extend. Change args for
465 * read.c (scm_read_hash_procedures): new variable.
466 (scm_read_hash_extend): new procedure.
467 (scm_get_hash_procedure): new procedure.
468 * (scm_lreadr): use scm_get_hash_procedure instead of an argument
469 for extended # processing.
470 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
471 scm_read_token): remove case_i, sharp arguments. Change callers.
473 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
475 * read.h (SCM_N_READ_OPTIONS): increase to 3.
476 (SCM_CASE_INSENSITIVE_P): define.
478 * read.c: add case-insensitive option to scm_read_opts.
479 * (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
480 to determine whether to convert symbol case.
481 (default_case_i): definition removed.
482 * read.c (scm_read_token): if case_i, downcase ic before doing
485 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
487 * configure.in: Added configuration option `guile-debug'.
488 Configure with --enable-guile-debug if you want a bunch of extra
489 functions used for debugging when developing Guile.
491 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
493 * procs.c (make-cclo): New undocumented debugging procedure: Make
494 compiled closure with internal procedure PROC and length LENGTH.
495 Only compiled if GUILE_DEBUG is defined.
497 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
499 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
501 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.

504 with 3 or more args internally to the evaluator.
506 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
508 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
509 with 3 or more args internally to the evaluator. This is mainly
510 because we don't want to pass entry and exit points of the
511 debug support twice, but it also seems to increase the speed of
512 the evaluator for such calls (e. g. (+ 1 2 3)).
514 * * backtrace.c (scm_display_application): New procedure:
515 display-application; Set fancy printing parameters individually
516 for different types of display (backtrace, error, application).
517 (These should of course be customizable!)
519 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
520 clear the CHECK-flags.
522 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
524 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
526 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
528 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
529 from pairs with a GLOC in the car.
531 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
532 otherwise `symbol-hash' will behave badly.
533 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
534 we get segmentation fault!
536 * * symbols.c: Added #include "weaks.h". New functions:
537 `builtin-bindings' and `builtin-weak-bindings'. (These will be
538 moved to an extraneous library when we split libguile.)
540 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
542 * filesys.c (scm_stat): stat now takes fport arguments too as
543 documented in the manual.
545 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
547 * debug.c (scm_single_step): Bugfix: Call continuation with
548 scm_call_continuation instead of throwing to it.
550 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
552 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
553 argument wasn't declared to be optional.
555 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
557 * stime.c (scm_init_stime): Add feature "current-time".
559 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
561 * throw.h: prototype for scm_exit_status.
562 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
563 args to derive an exit status. Allows (quit) to work from a
565 (scm_exit_status): new function.
568 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
570 * eval.c (scm_deval): Removed some old code.
571 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
573 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
576 * symbols.c (msymbolize): Bugfix: Must initialize property list to
579 * procs.c: Introduce the existent C function scm_thunk_p at the
580 Scheme level as well.
582 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
584 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
585 used from C to easily lookup the value of a symbol in the current
588 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
590 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
591 scm_init_unif in this file. This will also fix a previous problem
594 * configure.in: Added AM_MAINTAINER_MODE
596 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
598 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
601 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
603 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
604 source files that are not always included in libguile but should
605 have their dependencies calculated by automake. This variable is
606 recognized by automake, no further magic is needed.
607 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
608 to deal exclusively with *.lo files, as it seems. The *.o files
609 are built automatically when the corresponding *.lo file gets
612 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
614 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
617 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
619 * unif.c (scm_array_set_x): minor change to argument error checking.
621 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
623 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
624 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
625 They should only be included in the library at configure.in's
627 (libguile_la_LDADD): Include the appropriate .lo files here.
628 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
629 so we know when to build them (and their .lo bretheren).
630 * configure.in (LIBLOBJS): New substituted variable. We let
631 configure decide which .o files to include in LIBOBJS, and then
632 put the corresponding list of .lo files in LIBLOBJS. The latter
633 is what we pass to libtool.
634 * Makefile.in, configure: regenerated.
636 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
638 * symbols.c (scm_sysintern0): New function. Contains the core of
639 old scm_sysintern but doesn't take a second value argument.
640 (scm_sysintern): Now uses scm_sysintern0.
641 (scm_sysintern_no_module_lookup): Renamed to
642 scm_sysintern0_no_module_lookup and doesn't take a second value
645 * symbols.h (scm_sysintern0: Added declaration.
647 * options.c (scm_init_opts): Use scm_sysintern0 instead of
648 scm_sysintern when interning option keys. Otherwise we risk
649 destroying the values of already interned variables.
651 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
652 scheme-level boolean (use SCM_NFALSEP).
654 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
656 (scm_backtrace): New function. (C version of old function from
657 boot-9.scm) Motivation: Make it possible to display backtraces
658 without depending on boot-9.scm. (I'm uncertain if this
659 motivation is good enough...)
661 * root.h (scm_root_state): Add member the_last_stack_var.
662 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
664 * root.c (mark_root): Mark scm_the_last_stack_var.
666 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
669 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
671 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
672 1. mark_lazy_catch didn't mark the smob.
673 2. Both functions above have standard variants:
674 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
675 free_lazy_catch --> scm_free0.
677 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
679 * throw.c (scm_internal_lazy_catch): New function.
680 (scm_lazy_catch): Rewritten to use it.
681 (scm_ithrow): Handle the new lazy catch representation.
682 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
683 that doesn't have a jmpbuf is a lazy catch clause.
684 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
685 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
686 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
688 (scm_init_throw): Register the new lazy-catch smob type.
689 * throw.h (scm_internal_lazy_catch): decl for new function.
691 * throw.c (scm_internal_catch): Doc fixes.
693 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
694 configure.in. Including this might cause problems if applications
695 that link against libguile include their own copies of alloca, but
696 if they're using autoconf, they should be adding libguile to LIBS
697 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
698 the copy in libguile, and things will be okay. (I think.)
700 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
702 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
704 strop.h: move prototypes too.
706 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
708 * posix.c (scm_init_posix): don't intern EINTR since it's now done
711 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
712 etc. I deleted them from filesys.c long ago, but didn't
713 notice they were here too (although ineffective since
714 sys/stat.h wasn't included).
716 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
718 * eval.c: Don't define alloca in GCC case. gcc will automatically
719 use __builtin_alloca if appropriate.
721 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
723 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
724 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
725 that values of automatic variables are preserved. See comments
726 for safe_setjmp for details.
728 Change from Thomas Morgan:
729 * variable.c: Include eq.h.
730 (var_equal): New function.
731 (variable_smob): Use var_equal as the discriminator for variables.
733 * throw.c (s_throw): Remove extraneous declaration.
735 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
736 * eval.c: Add necessary CPP cruft to support that.
737 * configure, Makefile.in, scmconfig.h.in: regenerated.
739 Change from Thomas Morgan:
740 * procprop.c (scm_procedure_properties): Convert the Scheme
741 boolean returned by scm_procedure_p into a C boolean before using
742 it as a condition for SCM_ASSERT.
743 (scm_procedure_property): Likewise.
745 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
746 indications of Unixness.
749 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
751 * * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
753 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
755 * read.c (scm_lreadr): use scm_misc_error to improve one of the
756 "unknown # object" error messages.
758 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
759 (scm_i_index) and declare it static. Add a 'direction' argument
760 to indicate what way the search should go.
761 (scm_i_index): throw out-of-range error instead of wrong-type-arg
763 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
764 strop.h: remove scm_i_index, scm_i_rindex prototypes.
766 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
768 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
770 * * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
771 to avoid clash with various scsh forks.
773 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
775 The following two changes (ramap.c, throw.c) are motivated by the
776 apparent unportability of forward declarations of static arrays of
777 the form `static foo bar[];'.
779 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
780 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
782 * throw.c (scm_throw): Moved above scm_ithrow.
784 * options.h: Removed the extern declarations of scm_yes_sym and
785 scm_no_sym since these are static.
787 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
789 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
791 * Makefile.am: remove AWK=@AWK@.
792 Add a rule for generating errnos.list.
793 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
795 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
796 don't extract errnos, just set a variable (avoids the
797 need to recompile error.c just because configure is run.)
799 * unif.h: update prototypes.
800 * unif.c (scm_uniform_array_read,write): change the offset and
801 length arguments to start and end, for consistency.
803 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
805 * ioext.h: update prototypes.
806 * * ioext.c (scm_read_delimited_x): replaces scm_read_line and
807 scm_read_line_x, it's a more general procedure using an
808 interface from scsh. read-line and read-line! are now defined
810 * Note that the new read-line trims the terminator
811 by default, previously it was appended to the returned string. An
812 optional argument specifies how to process the terminator (scsh
813 compatible). For the old behaviour: (read-line port 'concat).
814 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
815 returns a pair, but is converted to multiple values if the scsh
818 socket.h: update prototypes.
819 * socket.c (scm_recvfrom): for consistency with other procedures,
820 take start and end as separate optional arguments.
821 * (scm_recv, scm_recvfrom): don't allow the second argument
822 to be a size, only a buffer. Change the scheme names to
823 recv! and recvfrom!. Don't return the buffer.
825 * ioext.h, posix.h: move prototypes too.
826 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
827 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
828 "read.h" and "unif.h".
829 * ioext.c: include "chars.h"
831 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
833 * dynl.c: The dynamic linking and module registration functions
834 are now defined even when dynamic linking is not available for the
835 host system. Some of their functionality can be done without
836 dynamic linking; when it's really needed, they throw errors.
838 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
840 * configure.in: Only define DYNAMIC_LINKING when one of the system
841 dependent functions is detected.
842 * dynl.c (scm_dynamic_func): New function to get the address of a
843 function in a dynamic object.
844 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
845 produced by scm_dynamic_func as the thing to call.
847 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
849 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
850 (scm_register_module_xxx, scm_registered_modules,
851 scm_clear_registered_modules): New functions.
853 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
855 * symbols.c (scm_sysintern): Renamed to
856 scm_sysintern_no_module_lookup.
857 (scm_sysintern): New function to take the place of the old
858 scm_sysintern. It uses the current toplevel lookup closure to give
859 the symbol its value. This is a temporary hack to put packages
860 like gtcltk into their own module.
861 (scm_can_use_top_level_lookup_closure_var): New variable to tell
862 us whether `scm_top_level_lookup_closure_var' has been initialized
864 * eval.c (scm_init_eval): Set it.
866 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
868 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
869 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
871 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
873 * (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
874 scm_sys_dup): deleted: FD capability will be added to other
876 * Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
877 scm_fd_free, fd_smob, scm_intern_fd.
878 * (scm_open): renamed from scm_sys_open. Return a port instead of
879 an FD object. Make the mode argument optional.
880 * (scm_sys_create): deleted, it's just a special case of open.
881 (scm_init_filesys): move interning of constants O_CREAT etc.,
882 here (were previously using SCM_CONST_LONG macro).
883 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
885 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
886 include "fports.h" and <stdio.h>
887 (scm_stat, scm_select): don't support FD objects.
889 * error.h: adjust scm_syserror_msg prototype.
890 * error.c (scm_syserror_msg): take an extra argument for errno.
891 Using the global value didn't always work, since it could be
892 reset by procedure calls in the message or args arguments.
894 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
895 I don't understand why the check was there (and what about the
898 * strop.c (scm_string_copy): allow shared substrings to be copied.
900 * unif.h: corresponding change to prototypes.
901 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
902 recognize two new optional arguments: offset and length. Allow
903 the port argument to be an integer (file descriptor, for scsh).
904 Include <unistd.h> for "read" prototype.
906 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
908 * socket.c: don't include filesys.h.
910 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
912 * Makefile.am: add AWK=@AWK@ (?)
914 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
916 Add a rule to generate errnos.c from errnos.
917 * error.c (scm_init_error): include errnos.c.
918 * errnos_cnvt.awk: new file, converts the list of errno codes to
920 * errnos_get.c: new file.
921 * errnos.default: new file, contains errnos to try if they can't
922 be extracted from errno.h.
923 * configure.in: if using GCC, try and extract errno codes from
927 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
929 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
930 * Makefile.am: Made libguile into a libtool library.
931 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
932 Set libtool_libs to indicate that libguile is a libtool library.
933 See guile/ChangeLog for details.
934 * .cvsignore: ignore "*.lo", the libtool library objects.
936 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
938 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
939 use htons in getservbyport argument.
941 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
943 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
944 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
947 * objprop.c (scm_object_property): No need to take the CDR of the
948 value returned by scm_object_properties, since Aug 20 change.
950 * configure.in: When checking for struct linger, #include
951 <sys/types.h> as well as <sys/socket.h>. I've never known
952 <sys/types.h> to cause any portability problems, and Solaris's
953 <sys/socket.h> needs it.
954 * configure: Rebuilt.
956 I think the Sun compiler has chosen a perverse way to interpret
957 ANSI declarations combined with K&R definitions. We'll
958 appease it a little bit. But when it invades France, we fight.
959 * print.c (scm_iprlist): Change 'tlr' argument to an int.
960 * print.h (scm_iprlist): Here too.
961 * numbers.c (scm_divbigdig): Change definition to match
962 declaration in numbers.h.
963 * unif.c (scm_makflo): Change definition to match declaration in
966 * init.c (scm_boot_guile): Don't return the value of
967 scm_boot_guile_1. This function doesn't return a value;
968 scm_boot_guile_1 doesn't return a value (or return at all).
970 * eval.c (unmemocopy): Add a semicolon to appease the Sun
973 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
974 compile. I have a feeling this function is a bad idea anyway ---
975 one should always test for features, not systems.
977 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
978 semicolons. Only pure luck kept this from being noticed earlier.
980 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
982 * socket.c (scm_recvfrom): Added missing semicolon.
984 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
986 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
987 the buffer and start and end positions for scsh networking
990 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
992 * configure.in: Revert previous change to this file; the problem
993 is due to transient automake weirdness.
994 * configure: Rebuilt.
996 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
997 PLUGIN/guile.libs. configure generates the latter from the former.
998 * Makefile.in: Rebuilt.
1000 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
1001 need this if we install scripts, like guile-snarf.
1002 * configure: Rebuilt.
1004 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1006 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
1008 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
1010 * socket.c (scm_addr_vector): fix faulty scm_listify.
1012 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
1014 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
1015 style block comment is no longer considered an error.
1017 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
1019 * PLUGIN/guile.libs.in: New file.
1020 * PLUGIN/guile.libs: Removed from repository.
1021 * configure.in: Create PLUGIN/guile.libs from
1022 PLUGIN/guile.libs.in. This is for including additonal libraries
1023 needed for dynamic linking.
1024 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
1025 instead of PLUGIN/guile.libs.
1027 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
1029 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
1031 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
1032 occurrences of the given element from the list, not just the
1033 first. This is how the Emacs Lisp functions behave, how the
1034 analogous Common Lisp functions behave, and (I believe) how the
1035 older Maclisp functions worked. I realize that this change may
1036 break code, but it seemed better to break it before the Guile
1039 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
1040 Their prototypes were already present in gc.h, but they weren't
1042 (scm_init_storage): Initialize scm_protects.
1043 * root.c (scm_protects): New element of scm_sys_protects.
1045 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
1047 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1049 * libguile.h: Added #include "libguile/net_db.h".
1051 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
1052 30 change. That file is only meant for communication between the
1053 configuration process and load.c. If code linked against libguile
1054 wants to get at the paths mentioned in libpath.h, it can call
1055 functions declared in load.h.
1057 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1059 * libguile.h: Removed #include "libguile/fdsocket.h"
1061 * net_db.c: Added #include <sys/socket.h>.
1063 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
1065 * filesys.c (scm_input_waiting_p): use select in preference to
1066 FIONREAD, since the latter doesn't detect EOF.
1067 Throw error if neither select nor FIONREAD available.
1069 * socket.c (scm_connect): take a port, not a fd object.
1070 (scm_fill_sockaddr): throw an error if fam is not recognised.
1071 (scm_bind): use scm_fill_sockaddr.
1072 (scm_listen): take a port, not a fd object.
1073 (scm_accept): take and return a port. return #f in the car if
1074 address can't be got
1075 (scm_sock_fd_to_port): new procedure.
1076 (scm_socket): use scm_sock_fd_to_port.
1077 (scm_addr_vector): throw error if unrecognised address type.
1078 take an extra argument with the calling procedure name.
1079 (scm_getsockname): take a port. return #f if address can't be got.
1080 (scm_getpeername): take a port. return #f if address can't be got.
1081 (scm_recvfrom): take a port. return #f for address component if can't
1083 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
1084 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
1086 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
1088 * throw.c (scm_internal_catch): Make body funcs and handler funcs
1089 use separate data pointers, to allow them to be designed
1090 independently and reused.
1091 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
1092 Renamed from catch_body, catch_handler, and uncaught_throw; made
1094 (struct scm_catch_body_data): Renamed from catch_body_data; moved
1096 (scm_catch): Use the above.
1097 (scm_throw): Don't bother printing a message for an uncaught
1098 throw; we establish a default handler in init.
1099 * throw.h (scm_internal_catch): Prototype updated.
1100 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
1102 (struct scm_body_thunk_data): New structure, used as data
1103 argument to scm_body_thunk.
1104 * init.c (struct main_func_closure): New structure, packaging up
1105 the data to pass to the user's main function.
1106 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
1107 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
1108 scm_internal_catch to establish a catch-all handler, using
1109 scm_handle_by_message. This replaces the special-case code in
1111 (invoke_main_func): Body function for scm_internal_catch; invoke
1112 the user's main function, using the main_func_closure pointer to
1113 decide what to pass it.
1114 * root.c (struct cwdr_body_data): Remove handler_proc member.
1115 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
1116 (cwdr_handler): Removed.
1118 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1120 * socket.h (SCM_P): update bind prototype.
1121 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
1122 include "feature.h".
1123 (scm_socket): return a port, not a file descriptor object.
1124 include "fports.h" and <unistd.h>
1125 (scm_bind): take a port, not a file descriptor object.
1126 take an extra argument for address args.
1128 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
1129 INADDR_NONE, INADDR_LOOPBACK.
1131 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1133 * init.c: include net_db.h and not fdsocket.h.
1134 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
1136 * Makefile.am: corresponding changes.
1137 * socket.h: renamed from fdsocket.h, fix names.
1138 * net_db.h: renamed from socket.h, fix names.
1139 * socket.c: renamed from fdsocket.c.
1140 remove _sys from procedure names.
1141 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
1142 add "socket" to features list.
1143 * net_db.c: renamed from socket.c.
1144 remove _sys from procedure names.
1145 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
1146 add "net-db" to features list.
1147 include "net_db.h". don't include <sys/socket.h> or
1150 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1152 * tags.h (scm_tags): Removed comma at end of last enumerator.
1154 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
1156 Don't use GCC extensions to allocate space for debugging frames.
1157 (Here he goes again! Why do we put up with this?!)
1158 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
1159 an scm_debug_info structure, not an in-line array of them. Add
1160 'info' member, to say how many vect elements we've used, for eval
1162 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
1163 a new variable debug_info_end to mark the end of vect, instead of
1164 the address of the 'info' pointer itself.
1165 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
1166 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
1167 (SCM_APPLY): Explicitly allocate space for debug.vect.
1168 * debug.c (scm_m_start_stack): Same, for vframe.vect.
1169 * stacks.c: Adjusted for new debug frame structure.
1170 (RELOC_INFO, RELOC_FRAME): New macros.
1171 (stack_depth, read_frames): Use them, and new scm_debug_frame
1172 element 'info', instead of magically knowing that eval frames have
1173 an info pointer sitting after vect.
1174 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
1176 (scm_init_stacks): Formatting tweaks.
1178 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
1180 Give GCC more control flow information, so it can be sure that
1181 variables aren't used uninitialized.
1182 * error.h (scm_error, scm_syserror, scm_syserror_msg,
1183 scm_sysmissing, scm_num_overflow, scm_out_of_range,
1184 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
1185 scm_misc_error): Tell GCC that these functions never return.
1186 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
1187 out the field type, call abort if SCM_ASSERT returns, to placate
1189 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
1190 scm_wta ever returns. We can't handle this case anyway, and this
1191 gives the optimizer more information.
1192 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
1193 scm_wta ever returns.
1195 In some cases, the code is fine, but GCC isn't smart enough to
1196 figure that out; this usually happens when one variable is only
1197 initialized and used when a particular condition holds true, and
1198 we know that condition will never change within a given invocation
1199 of the function. In this case, we simply initialize the variables
1200 to placate the compiler, hopefully to a value which will cause a
1201 crash if it is ever actually used.
1202 * print.c (scm_iprin1): Initialize mw_pos.
1203 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
1204 * throw.c (scm_ithrow): Initialize dynpair.
1205 * unif.c (scm_uniform_vector_ref): Initialize cra.
1206 * struct.c (init_struct): Initialize prot.
1207 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
1209 * strports.c (scm_eval_0str): Don't return uninitialized garbage
1210 if EXPR contains no expressions.
1212 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
1214 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
1215 cause an infinite loop (???). So much for the algebraic
1216 equivalency of variable-sized arrays and alloca...
1218 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
1220 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
1221 a SCM boolean, not a C boolean.
1223 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
1225 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
1226 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
1227 rules for raising scm_mtrigger. Previously, unfortunate but not
1228 unlikely circumstances could result in almost constant invokation
1229 of the gc. Now, this situations should be less likely, but they
1230 are not prevented completely.
1232 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
1234 * numbers.c (scm_fuck): Procedure removed; looks like old test
1236 * numbers.h: Prototype removed.
1238 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
1240 * debug.h (scm_debug_frame): Change `vect' member from an in-line
1241 array to a pointer, to match my Nov 21 change in eval.c.
1243 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1245 * libguile.h: Added #include "libguile/backtrace.h", #include
1246 "libguile/stacks.h".
1248 * strings.c (scm_string scm_make_string scm_string_ref
1249 scm_string_set_x scm_string_equal_p scm_string_append):
1250 Bugfix according to scm patch from Aubrey Jaffer:
1251 Corrected long-standing
1252 (not (eqv? (integer->char 128)
1253 (string-ref (make-string 1 (integer->char 128)) 0)))
1254 bug found by John Kozak <jk@noontide.demon.co.uk>.
1256 * strports.c, strports.h: Make scm_eval_0str return the value of
1257 the last expression evaluated (previously, it returned void).
1259 * strports.c, strports.h: New function: scm_read_0str. Does what
1262 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1264 * simpos.c (scm_getenv): return #f if string can't be found in the
1265 environment instead of throwing an exception, for compatibility
1266 with numerous other systems.
1268 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
1270 * Makefile.am (.c.x): Use guile-snarf.
1271 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
1273 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
1275 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1277 * backtrace.c (scm_display_error_message): Made non-static, and
1278 renamed from display_error_message.
1279 * backtrace.h (scm_display_error_message): Added extern decl.
1280 * throw.c (uncaught_throw): Use it to display the error message.
1282 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
1284 * inet_aton.c: Use #if 0, not #ifdef 0.
1286 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
1288 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
1289 to convert the returned value.
1290 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
1291 the offset argument.
1293 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1295 Add new interface to catch/throw, usable from C as well as
1297 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
1298 (scm_internal_catch): New function, replaces...
1299 (scm_catch_apply): Deleted.
1300 * throw.c (scm_catch_apply): Deleted; replaced with a more general
1301 mechanism which is a bit more code, but can be used nicely from C
1302 and implement the Scheme semantics as well.
1303 (scm_internal_catch): This is the replacement; it's named after
1304 the analogous function in Emacs.
1305 (scm_catch): Reimplemented in terms of the above.
1306 (struct catch_body_data, catch_body, catch_handler): New
1307 functions, used by scm_catch.
1308 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
1309 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
1310 support for new cwdr.
1312 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
1315 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
1317 * acconfig.h: Added DYNAMIC_LINKING symbol.
1318 * configure.in: Add option and checks for dynamic linking.
1319 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
1320 dynl.h: New files for dynamic linking support.
1321 * Makefile.am (libguile_a_SOURCES):
1323 (modinclude_HEADERS): Added "dynl.h".
1324 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
1326 * init.c (scm_boot_guile_1): Call
1327 scm_init_dynamic_linking to initialize dynamic linking support.
1329 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
1331 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
1332 (as we Schemers say). It needs to be global, so that I can tweak
1333 it for the proper operation of unexec.
1334 (scm_boot_guile_1_live): New variable, see above.
1336 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
1338 * guile-snarf.sh: Removed.
1339 * PLUGIN/guile.libs: Added dependency for -lm.
1340 * acinclude.m4: Renamed from aclocal.m4.
1341 * PLUGIN/greet: Removed.
1342 * Makefile.am, aclocal.m4: New files.
1343 * configure.in: Updated for Automake.
1345 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
1347 * eval.c (scm_definedp): Use top_level_lookup_closure_var
1348 and not top_level_lookup_thunk_var.
1350 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
1352 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
1354 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
1356 * eval.c (scm_definedp): Incompatibly changed to be a builtin
1357 Scheme function, instead of syntax. Single argument is now a
1360 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1362 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
1363 scm_ra_divide): Properly terminate statements passed as arguments
1364 to IVDEP macros. (Thanks to Bernard Urban.)
1366 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
1367 with non-constant sizes. (Thanks to Bernard Urban.)
1369 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1371 It's an "eval closure", not an "eval thunk." A thunk is a
1372 function of no arguments.
1373 * root.h (struct scm_root_state): Renamed
1374 top_level_lookup_closure_var from top_level_lookup_thunk_var.
1375 (scm_top_level_lookup_closure_var): Renamed from
1376 scm_top_level_lookup_thunk_var.
1377 * root.c (mark_root): Uses changed.
1378 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
1379 * init.c (scm_start_stack): Uses changed.
1380 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
1381 Change scheme-visible name to *top-level-lookup-closure* from
1382 *top-level-lookup-thunk*.
1384 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
1386 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
1387 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
1389 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
1391 * gc.c (struct scm_heap_seg_data): Doc fixes.
1393 * gc.c (scm_gc_sweep): Empty all segments' freelists before
1394 sweeping. Then, prepend each segment's free cells to its
1395 freelist, rather than wiping out the old value. (Thanks to Marius
1398 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
1399 scm_check_freelist, scm_debug_newcell): New functions and
1400 variables, for debugging freelist problems.
1401 * pairs.h (SCM_NEWCELL): New debugging version added.
1402 * gc.h (scm_debug_newcell): Added extern declaration, used by
1403 debugging version of SCM_NEWCELL.
1405 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1407 On some systems <libc.h> conflicts with <unistd.h>, and should not
1408 be #included at all.
1409 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
1410 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
1411 * configure.in: Call it.
1412 * posix.c, filesys.c: Use its results to decide whether or not to
1414 * configure, scmconfig.h.in: Rebuilt with autoconf and
1417 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1419 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
1420 pointer to the stdio stream before calling scm_setbuf0, so the
1421 latter will be able to retrieve it. I'm surprised this didn't
1422 segfault earlier. (Thanks to Christopher Lee.)
1424 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1426 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
1429 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1431 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
1432 number of stack narrowing specifier pairs. The first specifier in
1433 a pair controls inner border, the second the outer border. A
1434 number means cut that number of frames, a procedure object means
1435 cut until that object is found in operator position in a frame.
1437 * root.c (cwdr): Bugfix.
1439 * read.c: Recording of positions disabled by default.
1441 * procs.c (scm_closure_p): New function.
1443 * posix.c (scm_tmpnam): New function.
1445 * load.c: Added #include "throw.h".
1446 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
1449 * load.c, load.h (scm_read_and_eval_x): New function.
1451 * eval.c: Renamed debug option "deval" to "debug".
1453 (scm_eval_x): `eval!' is no longer accessible from the scheme
1454 level. Motivation: We can't allow operations which introduce
1455 glocs into the scheme level. Guile's type system can't handle
1456 these as data. Use `eval' or `read-and-eval!' as replacement.
1458 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
1459 SCM_CONSP since this is a macro!; Set vframe.prev to
1460 scm_last_debug_frame instead of 0. In this way we can look
1461 "above" the virtual start stack frame if we wish.
1462 (scm_debug_hang): New function: Useful for debugging Guile in
1463 certain tricky situations. Will probably be removed later...
1465 * debug.h: Changed semantics of debug option "backtrace". This
1466 option now only indicates whether we want automatic backtrace at
1469 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1471 * ports.c: #include "filesys.h"
1472 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
1474 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
1475 Motivation: This is system specific code which is related to file
1476 I/O. It also may use select. Added code by Gary Houston to
1477 detect presence of character in stdio buffers.
1479 * libguile.h: #include "libguile/libpath.h"
1481 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
1482 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
1483 SCM_SITE_DIR; Install libpath.h among the other include files.
1485 * load.c, load.h (scm_sys_package_data_dir): New function.
1487 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1489 * stacks.h: Bugfix: Don't use tail-array length field as stack
1490 length field! This screwed GC.
1492 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1494 * _scm.h: Added #ifndef around definition of macros min and max.
1496 * __scm.h: Added hooks for threads to plugin to in ints protection
1497 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
1498 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
1499 the main code in these macros duplicated and spread over multiple
1500 files. Renamed SCM_THREADS_SWITCHING_CODE ->
1501 SCM_THREAD_SWITCHING_CODE.
1503 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
1505 * snarf.h: New file.
1506 * guile-snarf.sh: New file.
1507 * Makefile.in (inner_h_files): Added snarf.h
1508 (ancillary, install, uninstall, distclean): Added actions for
1510 (.c.x): Use guile-snarf.
1511 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
1512 (gen_c_files): Note that these depend on guile-snarf.
1513 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
1514 now in "snarf.h". Added #include "snarf.h" to get them.
1515 * libguile.h: Added #include "snarf.h".
1516 (Patches applied and tweaked by Jim Blandy.)
1518 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1520 * socket.c: Use K&R style declaration for 'close'; the GNU coding
1521 standards suggest against providing prototypes for system
1522 functions. Thanks to Greg Troxel.
1524 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1526 * strports.c (scm_eval_0str): New function.
1527 #include "read.h", to get prototype for scm_read.
1528 * Makefile.in (strports.o): Update dependencies.
1529 * strports.h: New prototype.
1531 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
1532 scheme name from "int?" to "integer?". It seems to do the job.
1533 * numbers.h: Rename prototype too.
1534 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
1537 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
1538 scm_num_eq_p): Rename these according to R4RS conventions: call
1539 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
1540 to making libguile R4RS compliant without ice-9...
1542 * load.c (scm_sys_search_load_path): Search for files under all
1543 extensions listed in the %load-extensions variable. If FILENAME
1544 is absolute, return it unchanged, without searching the load path.
1545 (scm_loc_load_extensions): New variable, pointing to
1546 %load-extensions' value cell.
1547 (scm_init_load): Initialize it, and the value it points to.
1548 (scm_primitive_load_path): Improve error reporting.
1550 * load.c (scm_loc_load_hook): New variable, pointing to value cell
1551 of new Scheme variable %load-hook.
1552 (scm_primitive_load): Apply %load-hook to filename.
1554 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
1556 * configure.in: add tests for figuring out whether buffered data
1557 is available in a FILE structure, which is needed by char-ready.
1559 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
1562 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
1563 exceptions using misc_error instead of syserror. It seems a bit
1564 odd to throw an exception if a string can't be found in the
1565 environment, but it's consistent with open-file, stat etc.
1566 (simpos.h): remove sys_ from getenv.
1568 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
1569 occurs, throw an error instead of returning errno. Return value
1571 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1573 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1575 * filesys.c (scm_stat2scm): derive file type and permissions from
1576 the stat mode and append them to the returned vector.
1577 There isn't much overhead in doing this and it avoids the need to
1578 work with S_IRUSR et al. in Scheme.
1579 Define symbols scm_sym_regular etc.
1580 (scm_init_filesys): don't intern S_IRUSR etc.
1582 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1583 and s_primitive_load_path.
1585 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1587 * error.h: don't declare error symbols. prototype for scm_misc_error.
1589 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1592 * error.c: use SCM_SYMBOL to set up error keys.
1593 scm_misc_error: new procedure.
1595 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1597 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1598 between `#!' and `!#' is ignored.
1599 (skip_scsh_block_comment): New function.
1601 * feature.c (scm_set_program_arguments): New argument, FIRST.
1602 * feature.h: Update prototype.
1603 * init.c (scm_boot_guile_1): Pass new argument to
1604 scm_set_program_arguments.
1606 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1608 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1609 (scm_boot_guile): Call scm_set_program_arguments here, later than
1610 the old initialization.
1612 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1613 initialization procedure.
1614 - Delete in, out, err arguments; there are other perfectly good
1615 ways to override these when desired.
1616 - Delete result argument; this function shouldn't ever return.
1617 - Rename init_func argument to main_func, for less confusion.
1618 - Delete boot_cmd argument; main_func is more general.
1619 -Add 'closure' argument, to help people pass data to main_func
1620 without resorting to global variables.
1621 - Abort if reentered; don't bother returning an error code.
1622 - Call scm_init_standard_ports to set up the default/current
1623 standard ports; no need to pass them to scm_start_stack.
1624 - Remove code to evaluate the boot_cmd, and start the repl; let
1625 the user do something like that in main_func if they want.
1626 - Remove code to package up a return value; main_func can do any
1628 - Call exit (0), instead of returning.
1629 (scm_start_stack): Don't initialize the I/O ports here; that's
1630 weird. Delete in, out, err arguments. Move guts to
1631 scm_init_standard_ports, scm_stdio_to_port.
1632 (scm_init_standard_ports): New function, to set up current and
1633 default standard ports.
1634 (scm_start_stack, scm_restart_stack): Make these static.
1635 * init.h (scm_boot_guile): Adjust declaration.
1636 (scm_start_stack, scm_restart_stack): Remove externally
1637 visible declarations for these.
1638 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1640 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1641 written out several times in scm_start_stack.
1642 * fports.h: New declaration for the above.
1644 * feature.c (scm_set_program_arguments): New function.
1645 * feature.h: New declaration for the above.
1647 * ports.c: Formatting tweak.
1649 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1651 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1652 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1653 for obtaining the address of a car or cdr field. Motivation:
1654 &SCM_CXR make assumptions about the internal structure of the
1657 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1658 Motivation: see SCM_CXRLOC.
1660 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1661 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1662 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1663 Motivation: Safer use. Some other macros are defined in terms of
1664 these operations. If these are defined using the SCM_SETCXR
1665 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1666 to inefficiency and an <e1> with side-effects could potentially
1667 break. Also, these particular operations are heavily utilized in
1668 the garbage collector. In unoptimized code there will be a
1671 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1672 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
1673 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
1674 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
1675 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
1676 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1677 vports.c: Cleaned up use of pairs: Don't make any special
1678 assumptions about the internal structure of selectors and
1679 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1680 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1681 (Among other things, this change makes it easier to build Guile
1682 with certain compilers which have problems with casted lvalues.)
1684 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1686 * stacks.c: Improve selection of relevant stack frames when making
1687 a stack object. Introduce one level of indirection in the stack
1688 object to make it possible to "narrow" to a certain region of the
1689 stack. This facilitates making use of more clever algorithms (not
1690 implemented) for selecting relevant frames and gives a cleaner
1691 design since selection of frames can be done independently of
1692 extraction of frames from the real stack.
1693 (scm_stack_id): Also take #t as argument which means look at
1696 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1697 Turn n_tail into an integer directly representing current number
1698 of frames in stack. Add field tail.
1700 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1702 * debug.c (scm_make_memoized): Made it available at scheme level.
1703 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1704 SCM_NIMP before applying heavier predicates in argument checking.
1705 (scm_local_eval): Also take memoized object as argument.
1707 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1708 aren't created with zero length, but should such a strange
1709 creature suddenly turn up...
1711 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1713 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1714 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1716 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1718 * variable.c (scm_make_variable): Make the name hint optional, as
1720 (anonymous_variable_sym): Renamed from variable_sym. All uses
1723 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1724 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1725 of scm_primitive_load_path was also changed to
1726 "primitive-load-path", from "%try-load-path". Callers changed.
1727 We'd like to respect the convention that a function named
1728 "try-mumble" should behave just like the function called "mumble",
1729 but return #f instead of signalling some error.
1730 * load.h: Rename prototypes.
1732 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1734 * print.c (make_print_state, grow_print_state), print.h: Modified
1735 the print state representation: Don't use a tail array for
1736 recording of circular references. Resizing of the print state
1737 structure invalidates the print state pointer. To avoid passing
1738 around an indirect print state reference to all printing
1739 functions, we instead let the print state reference a resizable
1742 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1744 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1745 Don't crash when passed an improper list terminated by a
1746 non-immediate value.
1748 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1750 Allocate data for structures on an eight-byte boundary, as
1751 required by the tagging system.
1752 * struct.c (alloc_struct): New function.
1753 (scm_make_struct, scm_make_vtable_vtable): Call it.
1754 * struct.h (scm_struct_n_extra_words): Bump to 3.
1755 (scm_struct_i_ptr): New "field".
1756 * gc.c (scm_gc_sweep): When we need to free the data, use the
1757 information stored by alloc_struct to find the beginning of the
1758 block allocated to the structure, so we can free it.
1760 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1762 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1765 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1766 (scm_debug_info): New member: id.
1768 * stacks.c: Stacks are now represented as structs; Stacks have an
1769 id given to them by `start-stack'.
1770 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1772 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1773 Changed stack representation.
1775 * debug.c (scm_procedure_name): Try procedure property `name' for
1776 compiled closures aswell.
1778 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
1780 * eval.c: scm_i_name moved to gsubr.c
1781 (scm_m_define): Record names of all kinds of procedure
1782 objects. (Earlier, only closures were recorded.)
1784 * procprop.h: Added declaration of scm_i_name.
1786 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1787 (scm_make_gsubr): Record names of compiled closures.
1789 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1791 * debug.c, debug.h: Removed obsolete code.
1793 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1794 stacks.c: Renamed regs --> scm_contregs.
1796 * print.c (scm_free_print_state): Cleanup print state before
1797 returning it to pool. It is better to do it here than in
1798 scm_prin1 since scm_prin1 is called often.
1800 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1801 s_set_source_property_x): Check that first argument is a pair or a
1804 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1805 scm_i_line, scm_i_column and scm_i_breakpoint global.
1807 * init.c: Added #include "backtrace.h" and #include "stacks.h".
1808 (scm_boot_guile_1): Added calls to scm_init_backtrace and
1811 * debug.h: Added debug object smob declaration and macro
1814 * configure.in: Build with backtrace.o and stacks.o if debug
1817 * Makefile.in: Added entries for new files: backtrace.c,
1818 backtrace.h, stacks.c and stacks.h.
1820 * symbols.c (scm_sym2ovcell): Fixed documentation.
1822 * _scm.h (min, max): Added.
1824 * async.c: Moved `min' macro to _scm.h.
1826 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1827 SCM_BACKTRACE_INDENT.
1829 * eval.c: Added new debug options `maxdepth' and `indent'.
1831 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
1833 * print.h: Added selector SCM_PRINT_STATE.
1835 * print.c: New functions: scm_make_print_state,
1836 scm_free_print_state.
1838 * print.h: Added declarations for scm_make_print_state,
1839 scm_free_print_state.
1841 * debug.c (scm_m_start_stack): New acro.
1843 * debug.h: Small cleanup.
1845 * init.c (scm_boot_guile_1): Moved scm_init_debug below
1848 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

1870 declare functions with prototypes. (Patch thanks to Marius
1873 More prototype-related changes from Marius Vollmer:
1874 * gdb_interface.h: Wrapped header file in #ifdef/#endif
1875 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
1876 * ports.h (ptobfuns): Added prototypes. This means some casting in
1878 * fports.c: Added casts for initializations, since the functions
1879 are defined to take FILE * as their stream argument, not SCM.
1880 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
1881 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
1882 to `char *str_data' to conform to prototype.
1884 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1886 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
1888 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
1890 * stime.c, stime.h: use SCM_P method.
1892 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1894 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
1895 be given at least two arguments. Insist that lst's last element
1896 be a list, but don't make any requirements of its predecessors.
1898 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1900 * eval.c (scm_nconc2last): Revert last change; there seems to be
1901 other stuff going on here.
1903 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1905 * eval.c (scm_nconc2last): Make sure that each element of lst
1906 (which is a list of argument lists, except for the tail) is a
1907 proper list, i.e., finite and terminated by '().
1909 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1911 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
1914 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
1915 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
1918 * vectors.c (scm_make_vector): Fill vectors with the undefined
1919 value, to help make Guile Scheme code more portable to other
1922 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
1923 * symbols.h, tags.h: Doc fixes.
1925 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
1927 * async.c (scm_take_signal): Doc fixes.
1929 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
1931 * numbers.c (scm_divbigint): When the remainder is zero, we don't
1932 want to subtract it from the modulus; we just want to leave it
1935 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
1937 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
1940 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
1942 * throw.c (scm_catch_apply): Finished implementation of
1945 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
1947 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
1949 (scm_init_filesys): set "i/o-extensions" feature.
1952 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
1954 * Makefile.in (root.o): Correct dependencies.
1956 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
1958 * Makefile.in: Added dependency entry for root.o.
1960 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
1961 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
1963 * init.c (scm_start_stack): Set initial root continuation number
1966 * procs.c: New function: scm_thunk_p.
1968 * procs.h: Added declarations of scm_thunk_p.
1970 * root.c: Renamed `call-with-new-root' -->
1971 `call-with-dynamic-root'.
1972 (cwdr): Removed allocation of new root state. This should be done
1973 separately by use of scm_make_root.
1974 (scm_apply_with_dynamic_root): New function: Does what it
1975 sounds like. Needed when spawning threads.
1977 * root.h: Added member last_debug_frame to root state.
1978 Added #include "libguile/debug.h"
1980 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
1981 arguments. The motivation is that code in root.c needs catch
1982 functionality, and we want to avoid code duplication.
1983 New functions: scm_catch, scm_lazy_catch. These are wrappers for
1984 scm_catch_apply. scm_lazy_catch is intended to introduce catch
1985 handlers that run without popping the stack into the dynwind
1988 * throw.h: Added prototypes for scm_catch_apply and
1991 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1993 * root.h (scm_root, scm_set_root): Decouple thread support details
1994 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
1995 SCM_SET_THREAD_LOCAL_DATA.
1997 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
1998 and tortoise scanning loop.
2000 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
2002 * Makefile.in: Rebuild dependencies.
2004 * libguile.h: #include "libguile/print.h" before "smob.h", since
2005 the latter uses the print_state structure.
2007 * throw.c (scm_ithrow): Use the correct variable when checking to
2008 see if a given element of scm_dynwinds is a valid catch.
2010 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
2011 structure, abort; don't just silently ignore the garbage.
2013 * _scm.h: #include "print.h" here, since it seems to be used just
2015 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
2016 strports.c, unif.h: Don't #include "print.h".
2018 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2020 * feature.h (scm_loc_features): Removed external declaration.
2021 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
2023 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2025 * feature.c (scm_init_feature): Added threads feature (needs to be
2026 initialized here, since features doesn't exist when
2027 scm_init_threads is called).
2029 * libguile.h: Added #include "libguile/../threads/threads.h".
2030 (This is a kludge to get thread support working. This should be
2033 * configure.in, acconfig.h: Added flags for thread support.
2035 * scmsigs.c: Define `signal' to be `pthread_signal' if using
2038 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
2039 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
2042 * _scm.h: Added conditional #include "threads.h"
2044 * __scm.h (SCM_ASYNC_TICK): Added call to macro
2045 SCM_THREADS_SWITCHING_CODE.
2047 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
2048 allocate the basic dynamic root object.
2049 (scm_boot_guile): Added call to scm_init_root.
2051 * root.c, root.h: Added root smob.
2052 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
2053 functions: Implements dynamic roots mostly according to spec in
2054 SCM manual. Main difference is that the second argument is a
2055 throw handler rather than an error "thunk".
2057 * root.h: Added declaration of scm_init_root.
2059 * root.c: Added #include "genio.h", #include "smob.h", #include
2060 "pairs.h", #include "throw.h", #include "dynwind.h", #include
2062 (scm_init_root): Added #include "root.x".
2064 * throw.c: Added #include "stackchk.h"
2065 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
2066 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
2067 can be used in scm_call_with_new_root; Added reenabling of stack
2068 checking when catching a throw.
2070 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
2072 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
2074 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
2075 element is not found, as per R4RS.
2077 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2079 * list.c: Doc fixes throughout.
2081 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2083 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
2084 declare the char * to be const. Avoids a warning in rgx.c.
2086 * ports.h: spelling fix.
2088 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
2091 * load.c (scm_sys_try_load_path): throw an error if file not found
2092 (like it says it in NEWS).
2094 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2096 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
2097 PROPS slot to '(), not #f; it's an empty alist.
2099 * throw.h, throw.c: Use SCM_P instead of #if hair.
2101 Remove special support for uncaught throws; see throw.c for
2103 * throw.c (uncaught_throw): New function.
2104 (scm_ithrow): Call uncaught_throw if we don't find a throw
2105 target; don't mess with scm_bad_throw_vcell.
2106 (scm_bad_throw_vcell): Variable deleted.
2107 (scm_init_throw): Don't initialize it.
2109 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
2112 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2114 * numbers.c (scm_istr2int): If the number is short (as most
2115 numbers are), just call scm_small_istr2int to deal with it.
2116 (scm_small_istr2int): New function, created by un-#ifdefing the
2117 non-bignum version of scm_istr2int and renaming it.
2119 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
2121 * load.c (scm_sys_try_load): don't check whether value returned
2122 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
2123 Change the Scheme name from %try-load to primitive-load.
2125 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
2126 Can avoid passing a message, allowing it to be derived in the
2127 error handler (e.g., if we want to throw to the key both from
2130 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
2132 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
2133 references now have a new appearance which is more compact and
2134 also gives a clue about what the target of the reference is.
2135 By setting parameters in the print state, more fancy printing can
2136 be achieved. This is used by the (not yet commited) backtrace
2139 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
2141 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
2144 * print.c: Added #include "struct.h". Removed function
2147 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
2148 scm_iprin1. Removed prototype for scm_prlist.
2150 * arbiters.c (prinarb),
2151 async.c (print_async),
2152 debug.c (prindebugobj, prinmemoized),
2153 eval.c (prinprom, prinmacro),
2154 filesys.c (scm_fd_print, scm_dir_print),
2156 mallocs.c (prinmalloc),
2157 numbers.c, numbers.h (scm_floprint, scm_bigprint),
2158 smob.h (scm_smobfuns),
2159 srcprop.c (prinsrcprops),
2161 unif.c, unif.h (scm_raprin1, rapr1),
2162 variable.c (prin_var): Changed argument `int writing' to
2163 `scm_print_state *pstate'.
2165 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
2166 that it will be called before scm_init_print.
2168 * print.c (scm_prin1): Print states are now allocated when calling
2169 scm_prin1 and then passed around to all printing functions as an
2170 argument. A cache `print_state_pool' enables reuse of print
2172 (scm_make_print_state): New function.
2173 (scm_iprin1): Adaption to print states.
2174 (scm_iprlist): An initial "hare and tortoise" scan brings down
2175 time complexity to O (depth * N). (Better time complexity will be
2176 achieved when the printing code is completely rewritten.)
2178 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2180 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
2181 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
2182 it gets done whether or not the cache variable has a value.
2184 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2186 Distinguish #f and ().
2187 * __scm.h: #undef SICP.
2188 * pairs.h (SCM_EOL): Delete this definition, equating it with
2190 * tags.h (SCM_EOL): Give it a new definition here; I think I found
2191 the value it used to have. Doc fixes, too.
2193 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
2195 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
2196 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
2197 Lord's implementation of structs, allowing for tail arrays as
2198 described in the manual. Also fixed some bugs. (Both the interface
2199 and the implementation should be improved.)
2201 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
2203 * print.c, print.h: Closures now print like #<procedure foo (x)>.
2204 People who whish to see the source can do `(print-enable 'source)'.
2205 Removed #ifdef DEBUG_EXTENSIONS.
2207 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2209 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
2210 integer (assuming for now accepting an integer is a good thing).
2212 * error.c, fports.c: replace use of %S in lgh_error args with %s.
2213 %S will be used instead for write'ing arguments.
2215 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
2216 asserts. fix a few other asserts.
2217 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
2218 scm_uniform_vector_ref, scm_array_set_x,
2219 scm_dimensions_to_unform_array): change args in
2220 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
2221 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
2222 scm_substring_fill_x): likewise.
2223 gsubr.c (scm_gsubr_apply): likewise.
2224 eval.c (SCM_APPLY): likewise.
2226 * eval.c (4 places): replace scm_everr with lgh_error or
2229 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
2230 scm_memory_error): new procedures.
2231 scm_everr: deleted. can use scm_wta, dropping first two args.
2232 scm_error: convert NULL subr to SCM_BOOL_F.
2234 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
2237 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
2240 * error.c, error.h: new error keys: scm_arg_type_key,
2241 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
2243 scm_wta: reimplement using lgh_error instead of scm_everr.
2245 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
2247 * gdbint.c: scm_lread now has one more argument.
2249 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
2250 scm_port_\1; Added mutator scm_set_port_filename_x (used when
2251 loading source from non-file ports, which, e. g., happens when
2252 using the Emacs interface).
2254 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
2257 * read.c: Added code for recording of positions of source code
2258 expressions; New functions: recsexpr, scm_lreadrecparen;
2259 _scm_make_srcprops --> scm_make_srcprops
2260 (scm_flush_ws): Removed updating of positions counters. This work
2261 is already done by scm_gen_getc
2263 * read.h: Added prototype for scm_lreadrecparen
2265 * print.c: Added #include "alist.h"
2267 * eval.c: Added #include "hash.h"
2269 * eq.c: Added #include "ramap.h"

2275 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
2276 --> scm_make_srcprops
2278 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
2279 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
2280 function calls in the definition of the whash access macros.
2282 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
2284 * init.c (scm_boot_guile): Add level of indirection to
2285 scm_boot_guile_1() to ensure that stack base pointer is properly
2286 initialized. There was no guarantee that variable i was the
2287 highest/lowest variable on stack (i.e. the call frame of
2288 scm_boot_guile was not completely protected from gc).
2290 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
2292 * ports.h (scm_port_table): put back file_name, it will be used to
2293 support debugging. Undo related changes in fports.c, ioext.c,
2296 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2298 * ports.h (scm_port_table): remove file_name member for now, it seems
2300 * fports.c (scm_open_file): don't set file_name in PTAB.
2301 (prinfport): don't use file_name in PTAB.
2302 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
2303 * ports.c (scm_add_to_port_table): don't intialize file_name.
2304 (scm_port_file_name): remove for now.
2305 * gc.c (scm_gc_mark): don't mark PTAB file_name.
2307 * fports.h (scm_mkfile): prototype deleted.
2308 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
2310 * debug.c, unif.c: use scm_out_of_range instead of
2311 wta for range errors (ASSERT still needs work).
2313 * error.c, error.h (scm_out_of_range): new procedure.
2315 * error.c, error.h (scm_out_of_range_key): new key.
2317 * posix.c (scm_sync): #else was missing.
2319 * error.c, error.h: append _key to names scm_num_overflow and
2322 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
2323 of consing an empty list.
2324 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
2325 of macros, saves code and string space.
2326 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
2327 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
2328 lower case. Rename scm_syserror_m to scm_syserror_msg.
2329 error.h: prototypes for new procedures.
2331 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
2333 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
2335 * error.c, error.h: setup scm_num_overflow key.
2337 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
2338 Remove definition of SCM_OVSCM_FLOW.
2340 * fports.c (scm_open_file): use SCM_SYSERROR_M.
2342 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
2343 explicit message and args.
2345 * error.c, error.h, __scm.h: change system_error_sym to
2348 * error.c (system_error_sym): remove leading %% from the Scheme name
2351 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
2353 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2355 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
2356 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
2357 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
2358 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
2359 renamed. (These were introduced by unsupervised name
2362 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2364 * print.c: Added code for detection of circular references during
2365 printing. (init_ref_stack, grow_ref_stack): New functions. Added
2366 a hook for printing of closures (accessible via print options).
2367 This leads to a split of calls to scm_iprin1 into two classes:
2368 elementary print operations (e. g. the code which prints a smob)
2369 still use scm_iprin1 while top level calls (like scm_display) use
2370 scm_prin1. scm_prin1 begins by clearing the data structure used
2371 to record reference information.
2373 * print.h: Added declarations of scm_prin1 and scm_prlist.
2375 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
2377 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
2379 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
2381 * error.c (err_head): scm_iprin1 --> scm_prin1
2383 * debug.c: Adjusted header comment.
2387 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2389 * strerror.c: Doc fix.
2391 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2393 * gdbint.c (gdb_read): Now possible to run during GC.
2394 (unmark_port, remark_port): New functions.
2396 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
2398 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
2399 of allocating a new string object. Also, increase size by
2400 the factor 2 instead of 1.5.
2402 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
2404 * __scm.h (SCM_P): Corrected to run under traditional C.
2406 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
2409 * async.c: Calls to scm_sysintern corrected.
2411 * async.h (scm_async_clock): Redundant declaration removed.
2413 * continuations.c (scm_dynthrow): Redundant declaration removed.

2416 Definition typos corrected.
2418 * debug.h: Missing declarations of functions in debug.c added
2421 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2422 Missing declarations to functions in eval.c added.
2424 * filesys.c: Possibly uninitialized variable rv.
2426 * gc.h (scm_object_addr, scm_unhash_name): Missing
2427 declarations of functions defined in gc.c added.
2429 * genio.c: Possible typos str_data -> wstr_data. ???
2431 * genio.c: Possibly unintended shadowing of local variable
2432 `int c' (gotos out of scope of inner `c'). ???
2434 * init.c: Uninitialized `SCM last' may be used.
2436 * ioext.h: (scm_sys_isatty_p): Typo.
2438 * list.h (scm_list_head): Missing prototype for function in
2441 * numbers.c (scm_two_doubles): Changed from extern to static
2442 (is used only within numbers.c).
2444 * numbers.h: Repeated declarations removed.
2446 * ports.h (scm_close_all_ports_except): Declaration for the
2447 function defined in ports.c added.
2449 * posix.h: Missing declarations added.
2451 * procs.h (scm_make_subr_opt): Missing declaration added.
2453 * socket.h (scm_sys_gethost): Missing declaration added.
2455 * socket.h: Redundant declarations removed (they are in fdsocket.h).
2457 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
2458 Missing declarations added.
2460 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
2462 * struct.c: Uninitialized variable `SCM answer' may be used.
2464 * unif.c (l2ra): Declaration prototype.
2466 * unif.c (scm_array_equal_p): Dummy definition removed (it is
2467 defined in ramap.c).
2469 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
2470 Redundant declarations removed (they are in ramap.h).
2472 * variable.h (scm_make_udvariable,
2473 scm_make_undefined_variable): Declaration corrected to
2474 correspond variable.c.
2476 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
2477 Missing declarations added.
2479 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
2481 * Makefile.in (distclean): Don't forget to delete fd.h.
2483 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2485 * fd.h.in, tags.h: Trivial cleanups.
2487 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
2488 marksweep.h just declared functions from gc.c.
2489 * gc.h, libguile.h: Don't #include "marksweep.h".
2490 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2491 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
2492 dependencies updated.
2494 * libguile.h: Don't #include "files.h"; it's been deleted.
2496 * files.c (scm_sys_delete_file): Moved to filesys.c.
2497 File is now empty; deleted.
2499 * filesys.c: scm_sys_delete_file is now here. Remove
2500 #if's; they seem to rely on remnants of an old portability
2501 regimen. If the problems come up again, solve them properly,
2502 using autoconf. Specifically: Don't test M_SYSV, and #define
2503 remove to be unlink if it's #defined; don't use remove just
2504 because HAVE_STDC_HEADERS is #defined.
2505 * filesys.h: Add declarations for scm_sys_delete_file.
2506 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2507 files.o, files.h, files.c, and files.x.
2508 * init.c: Don't #include "files.h", and don't call scm_init_files.
2510 Use SCM_P instead of PROTO; the latter intrudes on the user's
2512 * params.h: Deleted; definition of SCM_P moved to...
2513 * __scm.h: ... here, where it replaces PROTO macro.
2514 * libguile.h, smob.h: Don't #include "params.h".
2515 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
2516 smob.h: Fix prototypes accordingly.
2517 * Makefile.in: Update dependencies.
2518 (inner_h_files): Remove params.h.
2520 * gc.c: #include "gc.h"; every module should include its header,
2521 to let the compiler cross-check the declarations against the
2524 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2525 simpos.h: #include "libguile/__scm.h".
2527 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2529 * init.c: Don't forget to #include smob.h and init.h.
2530 * Makefile.in: Dependencies updated.
2532 * smob.h: Use PROTO instead of #if __STDC__.
2534 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2536 * __scm.h: Doc fixes.
2538 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2539 <angles>; this allows `make depends' to work properly.
2541 * libguile.h: #include smob.h and pairs.h before the others; they
2542 define typedefs used by other headers.
2544 C files should #include only the header files they need, not
2545 libguile.h (which #includes all the header files); the pointless
2546 recompilation was wasting my time.
2547 * Makefile.in (all .o dependency lists): Regenerated.
2548 * libguile.h: Don't try to get a definition for size_t here...
2549 * __scm.h: Do it here.
2550 * _scm.h: Since this is the internal libguile header, put things
2551 here that all (or a majority) of the libguile files will want.
2552 Don't #include <libguile.h> here; that generates dependencies on
2553 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2554 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2555 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

2591 "unif.h", "throw.h", "tag.h", "symbols.h", "struct.h",

2646 * unif.c: Get "unif.h", "feature.h", "strop.h", "sequences.h",

2651 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
2652 * weaks.c: Get "weaks.h".
2654 * stackchk.h: #include "libguile/debug.h",
2656 * print.h, read.h: #include "options.h", since everyone who uses
2657 either of these files will need that.
2659 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2660 anyone who uses this file will need them to define the smob
2661 printing functions. Also, get markers.h, since people will need
2662 to #define the mark functions.
2664 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2665 * ports.h: ... to here.
2667 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2668 don't rely on archaic C default type rules.
2670 * fports.h: #include "libguile/ports.h", since you need that in
2671 order to parse this.
2673 * genio.h: #include "libguile/print.h", because you need that to
2674 parse this; don't bother #including "ports.h", since print.h gets
2677 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2679 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2680 this; it's now a reference to an element of *scm_root.
2682 * debug.h: Don't #include "options.h"; the compiler won't be able
2683 to find that once the headers are installed; instead, #include
2684 "libguile/options.h".
2685 * gc.h: Same, with marksweep.h.
2686 * mbstrings.h: Same, with symbols.h.
2687 * scmhob.h: Same, with _scm.h.
2688 * smob.h: Same, with params.h.
2690 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2691 C files; there's no need for this, and it forces recompilations
2694 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2696 * error.c (scm_error): declare scm_error_callback.
2698 * error.h: prototype for scm_error_callback.
2700 * __scm.h: define lgh_error.
2701 (SCM_SYSERROR): redefine using lgh_error.
2703 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2705 * error.c (scm_error): new procedure.
2707 * error.h: prototype for scm_error.
2709 * Makefile.in (install): install scmconfig.h from the current
2710 directory, not $(srcdir).
2712 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2714 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2715 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2716 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
2717 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
2718 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
2719 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2720 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2721 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2722 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2723 vports.h, weaks.h: #include "libguile/__scm.h", not
2724 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2725 dependencies are within libguile properly.
2727 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2729 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2730 when scmconfig.h doesn't exist.
2732 * load.c (scm_sys_try_load): Correct spelling.
2734 * feature.c (scm_loc_features): Make this static.
2736 * Makefile.in (libpath.h): Omit trailing slash from path. We
2737 shouldn't require it of users, so why put it here?
2739 Move code to initialize and search %load-path from ice-9 to C
2740 code, so we can use the load-path to find the ice-9 boot code;
2741 this makes it easier to run Guile without installing it. See
2742 corresponding changes in guile/Makefile.in.
2743 * feature.c: Move stuff concerned with the load path to load.c.
2744 (scm_compiled_library_path): Deleted.
2745 Don't #include libpath.h here.
2746 * feature.h: Don't mention scm_compiled_library_path.
2747 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2748 <sys/stat.h>, and <unistd.h> (if present).
2749 (R_OK): #define if the system hasn't deigned to.
2750 (scm_loc_load_path): New variable.
2751 (scm_init_load_path, scm_sys_search_load_path,
2752 scm_sys_try_load_path): New functions.
2753 (scm_init_load): Initialize scm_loc_load_path to point to the
2754 value cell of the Scheme %load-path variable.
2755 * load.h: Add declarations for scm_sys_search_load_path,
2756 scm_sys_try_load_path.
2757 * init.c: Call scm_init_load_path.
2758 * Makefile.in (feature.o, load.o): Dependencies updated.
2760 * load.c, load.h: Rewrite using PROTO macro.
2762 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2764 * gc.c (scm_cellp): New function: C predicate to determine if an
2765 SCM value can be regarded as a pointer to a cell on the heap.
2767 * gc.h: Added declaration of scm_cellp.
2769 * gdb_interface.h: New file: The GDB interface header from the GDB
2772 * gdbint.c: New file: GDB interface.
2774 * gdbint.h: New file: GDB interface.
2776 * libguile.h: Added #include <libguile/gdbint.h>.
2778 * init.c (scm_boot_guile): Added scm_init_gdbint.
2780 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2781 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2782 found if object files and source are kept separate).
2784 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2786 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2788 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2790 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2791 TK_SRC_DIR; they're not relevant any more.
2793 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2794 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2796 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2798 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2799 search path, so we can find the <libguile/MUMBLE.h> headers.
2801 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2803 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2804 implicit in the .c.o rule.
2805 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2808 Put the library path in a header file, instead of passing it on
2809 the command line in every compilation.
2810 * Makefile.in (libpath.h): New target.
2811 (feature.o): Depend on libpath.h.
2812 (clean): Delete libpath.h.
2813 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2814 * feature.c: ... #include "libpath.h" here.
2815 * .cvsignore: Ignore libpath.h.
2817 Don't install the unwashed masses of Guile header files in the
2818 main #include path; put most of them in a subdirectory called
2819 'libguile'. This avoids naming conflicts between Guile header
2820 files and system header files (of which there were a few).
2821 * Makefile.in (pkgincludedir): Deleted.
2822 (innerincludedir): New variable; this and $(includedir) are enough.
2823 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
2824 (installed_h_files): Divide this up. Now this variable lists
2825 those header files which should go into $(includedir) (i.e. appear
2826 directly in the #include path), and ...
2827 (inner_h_files): ... this new variable says which files appear in
2828 a subdirectory, and are referred to as <libguile/mumble.h>.
2829 (h_files): List them both.
2830 (install): Create innerincludedir, not pkgincludedir. Put
2831 the installed_h_files and inner_h_files in their proper places.
2832 (uninstall): Corresponding changes.
2833 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2834 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2835 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
2836 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
2837 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
2838 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2839 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2840 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2841 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2842 vports.h, weaks.h: Find __scm.h in its new location.
2843 * __scm.h: Find scmconfig.h and tags.h in their new locations
2844 (they're both "inner" files).
2846 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
2848 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
2850 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2852 * posix.c: Doc fixes.
2854 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
2856 * socket.c: Don't include a prototype for inet_aton; just use a
2857 K&R style declaration, to avoid warnings but minimize the chance
2858 of conflicts with the system.
2860 On NextStep, <utime.h> doesn't define struct utime, unless we
2861 #define _POSIX_SOURCE before #including it.
2862 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
2863 * acconfig.h: New comment text for above CPP symbol.
2864 * configure.in: Call it.
2865 * posix.c: #define _POSIX_SOURCE if it seems necessary.
2867 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
2869 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
2870 testing for __EMX__.
2872 * posix.c: #include <libc.h>, if it exists.
2874 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
2875 don't even know if the latter exists.
2877 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
2878 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
2879 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
2881 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
2883 (scm_init_posix): Use them when initializing the Scheme constants
2886 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2888 * Makefile.in (libdir, includedir, bindir): Use the
2889 autoconf-supplied values, instead of deriving them ourselves.
2890 (pkgincludedir, datadir, pkgdatadir): New variables.
2891 (install, uninstall): Put the header files in a special
2892 subdirectory, not in the main search path.
2894 * Makefile.in (ALL_CFLAGS): Provide the proper value for
2895 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
2897 * Makefile.in (IMPLPATH): Deleted; never used.
2899 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
2900 on the Tcl/Tk source any more.
2901 (INCLUDE_CFLAGS): Remove references to the above.
2903 * Makefile.in (version.o): Corrected dependencies.
2905 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
2907 * libguile.h: #include "version.h"
2909 * init.c (scm_boot_guile): Call scm_init_version.
2910 * gscm.c (gscm_run_scm): Call scm_init_version.
2912 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
2913 GUILE_VERSION): AC_DEFINE these.
2914 (acconfig.h): #undef the above symbols.
2916 * Makefile.in (libobjs): Add version.o.
2917 (installed_h_files): Add version.h.
2918 (c_files): Add version.c.
2919 (gen_c_files): Add version.x.
2920 (version.o): New rule.
2921 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
2922 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
2923 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
2924 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
2925 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
2926 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
2927 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
2928 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
2929 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
2930 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
2931 weaks.o): Add version.h to dependency lists.
2932 (markers.o): Remove duplicate rule.
2934 * version.h: New file.
2936 * version.c: New file.
2938 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2940 * symbols.c (scm_strhash): scm_downcase is now a function, not an
2941 array; use it appropriately. Since GCC is quite happy to
2942 subscript functions, it never warned us about this; we should use
2943 -Wpointer-arith in the future. I guess we never tested
2946 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2948 * socket.c: Doc and copyright fixes.
2950 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2952 * debug.c: Fixed and improved gdb support.
2954 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2956 * socket.c: Added declaration of inet_aton to avoid compiler
2957 warning. (Hope this solution is correct.)
2959 * stime.c: Added declaration of ftime. (This is missing in
2962 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
2964 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2966 * Makefile.in (c_files): add strerror.c.
2968 * strerror.c: new file from Emacs' sysdep.c.
2969 maybe configure should also check for sys_errlist.
2971 * configure.in (AC_REPLACE_FUNCS): add strerror.
2973 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2975 * debug.c (scm_init_debug): Added initialization for
2976 scm_evaluator_traps.
2978 * debug.h, debug.c: Various name changes.
2979 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
2980 "debug-options-interface". See commentary in options.c.
2982 * options.h, options.c: Options now have documentation strings.
2983 Also added a long explanatory commentary.
2985 * eval.c, print.h, print.c, read.h, read.c: Modifications to
2988 * gscm.c, init.c, root.c, throw.c: Bug fixes:
2989 last_debug_info_frame is now updated in all cases.
2991 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
2994 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2996 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
2997 Added option STACK_CHECKING.
2999 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3001 * Makefile.in: Added {debug,options,srcprop}.{h,c}
3003 * __scm.h: Removed symbols for debugging support.
3005 * acconfig.h: Added symbols for debugging support.
3007 * configure.in: Added user option for debugging support.
3008 --enable-debug will include the debugging code into libguile.a.
3010 * continuations.c (scm_make_cont): Enlarged the #if 0 around
3011 scm_relocate_chunk_to_heap.
3013 * debug.c: New file: low-level debugging support. It also
3014 includes support for debugging with gdb. (The extensions to gdb
3015 are written by Per Bothner at Cygnus.)
3017 * debug.h: New file: low-level debugging support.
3019 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
3020 argument pairs. Extensive modifications to the debugging
3021 evaluator. Added "SECTION:" commentaries to clarify what happens
3022 when, during double compilation. Renamed EVALIMP --> EVALIM.
3023 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
3024 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
3025 the beginning of the file. New procedure: scm_unmemocopy.
3026 Added some global state variables needed by the debugging
3027 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
3028 check_entry, check_apply, check_exit, debug_options and
3029 evaluator_traps. New acro: undefine.
3031 * eval.h: Renamed EVAL --> XEVAL.
3033 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
3034 --> scm_make_weak_key_hash_table.
3036 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
3037 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
3039 * libguile.h: Conditionally include debug.h
3041 * objprop.c (scm_object_properties, scm_set_object_properties_x):
3042 scm_object_properties shouldn't return handle. `handle' now gets
3043 initialized in scm_set_object_properties_x. scm_object_properties
3044 doesn't any longer create an entry in scm_object_whash.
3046 * options.c: New file: handling of run time options.
3048 * options.h: New file: handling of run time options.
3050 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
3052 * print.c: New procedure: scm_print_options
3054 * print.h: Defines for print options.
3056 * read.c: New procedure: scm_read_options
3058 * read.h: Defines for reader options.
3060 * root.h: Added scm_source_whash among scm_sys_protects.
3062 * srcprop.c: New file: source properties.
3064 * srcprop.h: New file: source properties.
3066 * throw.c (jbsmob): Jump buffers are now correctly allocated.
3067 (Bug found by A. Green.)
3069 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3071 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3073 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
3075 * libguile.h: #include "objprop.h"; I guess this was forgotten.
3077 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
3078 and should be called by the final client.
3080 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
3082 * gc.h: Use the PROTO macro when declaring functions.
3083 * gc.c: Use the PROTO macro when declaring static functions.
3084 Remove the CPP hair around function definitions.
3086 * gc.c (scm_init_storage): Initialize scm_asyncs.
3088 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
3089 preprocessor symbol; "__scm.h" is where it might get #defined.
3090 * __scm.h: Similar: #include <scmconfig.h> before testing
3093 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
3095 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
3097 * init.c (scm_boot_guile): Add init_func argument; call
3098 (*init_func) instead of calling scm_appinit; it's ucky to
3099 hard-code names for the user's procedures.
3100 * init.h (scm_boot_guile): Adjust declaration.
3102 * __scm.h (PROTO): New macro, for declaring functions with
3105 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
3106 eliminate all the __STDC__ conditionals.
3107 (scm_boot_guile): Add declaration.
3108 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
3109 Remove __STDC__ conditionals around function definitions; the
3110 declarations in init.h will provide the same information, more
3113 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
3114 complain about it in the error message; the error message is
3115 adequate without that note, and there's nothing the user can do
3118 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
3120 * Makefile.in (ancillary): Drop def.sed.
3122 * posix.c (scm_init_posix): Use numeric values, rather than
3123 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
3124 F_OK. The symbols aren't available on some systems, and I'm
3125 pretty sure their values are fixed by common widespread practice.
3126 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
3128 More functions unavailable on some systems.
3129 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
3130 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
3132 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3133 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
3134 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
3135 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
3136 stub that signals an error as the #else.
3138 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
3140 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
3142 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
3144 * unif.c: include ramap.h.
3146 * read.c (endif): case_insensative_p renamed case_insensitive_p.
3148 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
3150 * ports.c: include sys/ioctl.h.
3152 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
3154 * configure.in: check for sys/ioctl.h.
3156 * ports.c: include <malloc.h> not "malloc.h".
3158 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3160 * fports.c: remove ttyname and tmpnam declarations.
3162 * posix.c: fewer ttyname declarations.
3164 * fports.c: include <string.h> not "string.h".
3166 * init.c, ioext.c: include string.h and unistd.h.
3168 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3170 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
3171 genio.c, simpos.c, vports.c: include string.h.
3173 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
3175 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
3177 (scm_addr_buffer_size): change type from scm_sizet to int.
3178 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
3179 from scm_sizet to int.
3181 * error.c: include unistd.h.
3183 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
3186 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
3188 * __scm.hd, def.sed: deleted.
3190 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
3192 Changes for NeXT, suggested by Robert Brown.
3193 * configure.in: Call AC_TYPE_MODE_T.
3194 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
3195 NeXT. Put header file list in alphabetical order.
3196 * configure, scmconfig.h.in: Regenerated.
3197 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
3199 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
3202 * acconfig.h: New file, providing documentation for the CPP
3203 symbols defined in configure.in
3204 * acconfig-1.5.h: Removed; superceded by the above.
3206 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
3208 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
3210 * fports.c (scm_open_file): don't return #f, throw error.
3212 * ioext.c (fileno): renamed from %fileno.
3213 (soft-fileno): deleted.
3215 * ports.c (scm_port_revealed): don't need to check for -1 from
3217 (scm_set_port_revealed_x): return unspecified, not #f.
3219 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
3221 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
3223 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
3225 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
3227 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3229 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
3230 This is necessary on Ultrix, and doesn't hurt portability.
3232 * Makefile.in (dist-dir): New target, implementing a new dist system.
3233 (installed_h_files): Put in alphabetical order.
3234 Remove duplicate entries for markers.h and unif.h.
3235 (c_files): Remove duplicate entries for markers.c.
3236 (ancillary): Renamed from anillery; all uses changed. Remove
3237 PLUGIN; it's a directory, and needs special treatment in dist-dir.
3238 Remove all the ../doc/* files; doc/Makefile.in handles that.
3240 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
3242 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
3243 every if must have an else, or else the whole command has a
3244 non-zero exit code whenever the if's condition is false.
3246 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
3248 * posix.c: include string.h.
3250 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
3252 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
3255 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
3256 Remove leading % from scheme names.
3257 Do not return error values, call SCM_SYSERROR or similar.
3259 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
3261 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
3263 * struct.c (scm_init_struct): new file.
3265 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
3267 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
3268 (scm_list_head): added list-head for rapidly chopping argument
3269 lists off of longer lists (and similar).
3271 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
3273 * objprop.c (scm_object_property): assq the cdr of the whash
3274 handle for obj, not the handle itself.
3276 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
3278 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
3279 weak hash tables last of all marking to avoid an obscure gc bug.
3280 WARNING: circular lists stored in a weak hash table will hose us.
3282 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
3284 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
3285 new functions similar to scm_substring_move_left_x and
3286 scm_substring_move_right_x.
3288 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
3290 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
3293 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
3295 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
3297 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
3299 * strports.c (scm_strprint_obj): convenience function. C for
3300 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
3302 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
3303 removed to a separate library
3305 * init.c (scm_boot_guile): copied from guile-tcl.c.
3306 Initialization specific to tcl interpreters removed.
3308 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
3310 * ports.c (scm_ports_prehistory): size malloced here doesn't
3311 matter so long as it is non-0 (got rid of "* 4").
3313 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
3315 * gscm.h: gscm_mkarray eliminated (presumably was not being used
3316 since its definition was bogus).
3318 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
3320 * mallocs.[ch]: back again (for rx at least).
3322 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
3324 * ports.c: removed functions relating to the mapping between ports
3325 and descriptors. (That stuff is unix-specific and should be collected
3326 in a separate library).
3328 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
3329 (Tom Mckay@avanticorp.com)
3331 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
3333 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
3334 handled correctly (SCM_FREEP was applied to them) -- test for
3335 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
3336 being overwritten with #f. (brown@grettir.bibliotech.com)
3338 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
3340 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
3341 for a specific symbol or for all symbols.
3343 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
3345 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
3346 keys and weak values confused).
3348 Thu Mar 14 22:20:20 1996 Tom Lord <lord@beehive>
3350 * list.c (scm_last_pair): map '()=>'()
3352 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>
3354 * pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:
3355 Generalized assoc and hash-table functions.
3356 Factored pairs.c into multiple files.
3358 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
3360 * gscm.c (gscm_run_scm): got rid of objprop.
3362 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
3364 * genio.c (scm_getc):
3365 NOTE: fgetc may not be interruptable.
3367 * procprop.c (scm_stand_in_scm_proc):
3368 NOTE: don't use a alist here.
3369 (scm_set_procedure_properties_x): fix type checking throughout this file.
3371 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
3373 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
3374 after freeing part of the port table.
3376 Thu Feb 29 16:21:17 1996 Tom Lord <lord@beehive>
3378 * strports.c (scm_mkstrport):
3379 * vports.c (scm_make_soft_port): allocate a port table entry
3380 (possibly triggering gc) before setting the tag of the corresponding
3383 * pairs.c (scm_delq_x): never throw an error.
3385 * vectors.c (scm_make_vector): made the default vector fill argument
