1 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
3 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
4 sure how this was supposed to work.
5 (scm_async_click): don't send SCM_TICK_SIGNAL.
6 (scm_init_async): don't initialize %tick-thunk.
8 * the following change doesn't affect the Scheme interface:
9 gc-thunk is called at the end of garbage collection. however it's
10 no longer implemented by pretending it's a signal.
12 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
13 system async corresponding to scm_gc_thunk.
14 * async.h: declare scm_gc_async.
15 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
16 gc-thunk directly, instead of going through a signal handler.
17 (scm_gc_async): new variable, points to the GC system-async.
18 (scm_init_async): save the GC async as scm_gc_async instead
19 of using system_signal_asyncs.
20 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
22 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
24 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
25 Don't screw up if we're interrupted.
26 * Makefile.in: Regeneradet.
28 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
30 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
32 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
33 we're not using AM_INIT_GUILE_MODULE any more.
34 * Makefile.in: Reneregated.
36 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
38 Functions for finding variable bindings, grace à Tim Pierce.
39 * * gh_data.c (gh_lookup, gh_module_lookup): New functions.
40 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
42 Get 'make dist' to work again.
43 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
44 * Makefile.in: Regenerated, like a surry without a fringe on top.
46 Changes for reduced Guile distribution: one configure script,
48 * configure.in, configure: Removed.
49 * acconfig.h, acinclude.m4: Moved to parent directory, where the
50 real configure script lives.
51 * Makefile.in, scmconfig.h.in: Regenerated.
53 * init.c: #include "script.h", to get prototype for script.c's
56 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
58 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
59 scm_must_malloc, not raw malloc.
61 * script.c (scm_compile_shell_switches): Dyke out debugging output
64 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
66 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
68 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
69 system has them. Hope this is safe. Previously
70 sys/timeb.h was included if HAVE_FTIME was defined or if
71 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
72 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
74 * ioext.c (scm_setfileno): add missing third argument to
77 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
79 * eq.c (scm_equal_p): Correctly compare strings of different
80 varieties. (Thanks to Tim Pierce.)
82 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
84 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
85 #! block comment must occur on a line all by itself.
87 Move most of the guts of shell command processing into libguile,
88 so guile.c can be very small (and eventuallly auto-generated. (I
89 mean, generated mechanically, not self-generated. Hmm.))
90 * guile.c, script.c, script.h: New source files.
91 * init.c (scm_boot_guile_1): Call scm_init_script.
92 * libguile.h: #include "script.h".
93 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
94 targets, for new executable.
95 (libguile_la_SOURCES): Mention script.c.
96 (modinclude_HEADERS): Add script.h.
97 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
98 not dynamic linking is enabled. This is because we're generating
99 executables now. Move CY_AC_WITH_THREADS call after those, so the
100 values of cy_cv_threads_libs captures the libs chosen above.
101 * Makefile.in, configure, aclocal.m4: Regenerated.
103 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
104 We don't maintain this interface any more, and it just confuses
107 * alloca.c: #include <scmconfig.h>, not <config.h>.
108 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
109 it'll get included in disties.
111 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
113 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
114 be distributed, because they confuse people.
115 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
117 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
119 * configure.in: check for presence of gethostent (not present on
121 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
122 * configure, scmconfig.h.in: Regenerated.
124 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
126 * backtrace.c (scm_backtrace): Split message string across
127 newlines properly. GCC is more tolerant of this than other

132 Merge threads directory into libguile.
133 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,

138 (modinclude_HEADERS): Add threads.h, coop-defs.h.
139 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
140 coop-threads.c.cygnus, coop-threads.h.cygnus.
141 * configure.in: If we're using threads, include threads.o in
143 * _scm.h, libguile.h: threads.h lives in this directory now.
144 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
145 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
146 currently used, but brought along for information's sake.
147 * ChangeLog-threads: log from old 'threads' directory.
148 * Makefile.in, configure: Rebuilt.
150 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
152 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not

157 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
159 Merge GH interface library into libguile.
160 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
161 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
162 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
163 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
165 (EXTRA_libguile_la_SOURCES): ... here.
166 (pkginclude_HEADERS): Add variable, to get gh.h installed.
167 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
168 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
169 New variables, describing how to build the gh test programs.
170 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
171 build the test programs, and we probably should have been linking
172 libguile.la against them all along, to support AIX shared libs.
173 Add cflags for threads to CFLAGS; add libs for threads to new
174 variable THREAD_LIBS, used in Makefile.am.
175 * ChangeLog-gh: log from old `gh' subdirectory.
176 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
178 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
180 * acconfig.h: Undo change of Apr 9; including the definition of
181 PACKAGE in the guile headers conflicts with applications' own
183 * scmconfig.h.in: Regenerated.
185 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

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

214 * acconfig.h: Added entry for PACKAGE.
215 * scmconfig.h.in: Regenerated.
217 Changes to work with automake-1.1n, which has better libtool support.
218 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
219 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
221 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
223 * Makefile.in: Rebuild.

231 stime.h, posix.h: update prototypes.
232 (bdtime2c, setzone, restorezone): new static procedures.
233 (scm_mktime, scm_strftime): use them.
234 (scm_strftime): don't call mktime before strftime. Use
235 filltime for return value.
236 (filltime): convert NULL zname to #f.
237 * (scm_strptime): return a count of characters consumed, not
238 the remaining string.
240 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
242 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.

249 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
251 * stime.c (scm_init_stime): don't define ticks/sec.
252 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
253 return value problem and is still portable.)
255 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
257 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
258 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
259 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
260 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
261 cpp_err_symbols.c): Corresponding changes.
262 * Makefile.in: Regenerated.
264 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
266 * posix.c (scm_putenv): don't check HAVE_PUTENV.
267 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
268 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
269 * putenv.c: new file, from sh-utils 1.12.
271 * posix.c (scm_environ): use malloc in place of scm_must_malloc
272 since allocation isn't for Scheme objects.
273 (scm_putenv): copy strings before placing in the environment.
275 * stime.c (scm_current_time): throw an error if time returns -1,
276 instead of returning #f.
277 (scm_get_internal_real_time, scm_get_internal_real_time): use
278 scm_long2num for return value instead of SCM_MAKINUM.
280 * stime.h: prototypes updated.
282 * stime.c (scm_time_in_msec): apparently unused, deleted.

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

306 * * posix.c (scm_mknod): split the mode argument into type and perms
307 arguments, like the extra fields returned by stat.
309 * fports.c (scm_pipob): set the close, free and print procedures.
310 (scm_close_pipe): new procedure.
312 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,

315 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
317 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
318 wan't defined. Don't include fd.h.
320 * Previously fd.h was regenerated whenever configure was run,
321 forcing a couple of files to be recompiled.
323 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
324 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
325 Check for _fileno as well as _file.
327 * ioext.c: don't fd.h.
328 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
331 * Change the stratigy for getting information about errno
332 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
333 generating lists of symbols during the build process, which will
334 not always work, include comprehensive lists in the distribution.
335 To help keep the lists up to date, the "check_signals" and
336 "check_errnos" make targets can be used.
338 * configure.in: don't check for a command to extract errno codes.
339 * Makefile.am: update file lists, remove errnos.list and errnos.c
340 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
341 check_errnos targets.
342 (CLEANFILES): remove errnos.c and errnos.list, add
343 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new

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

406 * acconfig.h: Removed PACKAGE.
408 * scmconfig.h.in: Regenerated.
410 * snarf.h: g++ says it's non-portable not to specify the first
411 argument in a varargs declaration. I introduced the first
412 argument by using preprocessor conditionals.
414 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
416 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
417 (scm_freopen): use RO string macros for filename and modes.

423 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
424 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
426 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
427 use SCM_ROSTRINGP and SCM_ROCHARS.

446 * error.h: prototype for scm_error_scm.
448 * error.c (scm_error_scm): new procedure, reimplements scm-error
449 in C and uses scm_error.
451 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
453 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
454 pointer to the Scheme variable read-hash-procedures and intern it
455 in scm_init_read. Modify scm_read_hash_extend and
456 scm_get_hash_procedure to use the pointer.
458 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
460 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
461 (SCM_KEYWORD_STYLE): defined.
463 * read.c (scm_read_opts): add a keywords option. This isn't a
464 boolean option, in case someone wants to add support for DSSSL
466 Setup scm_keyword_prefix symbol.
467 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
469 * I've left keyword support disabled by default, since it doesn't
470 seem to break the module system and it gives R4RS standard behaviour.
471 It can be reactivated with (read-set! keywords 'prefix).
473 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
475 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
476 before constructing arbiter.

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

511 * (scm_lreadr): use scm_get_hash_procedure instead of an argument
512 for extended # processing.
513 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
514 scm_read_token): remove case_i, sharp arguments. Change callers.
516 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
518 * read.h (SCM_N_READ_OPTIONS): increase to 3.
519 (SCM_CASE_INSENSITIVE_P): define.
521 * read.c: add case-insensitive option to scm_read_opts.
522 * (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
523 to determine whether to convert symbol case.
524 (default_case_i): definition removed.
525 * read.c (scm_read_token): if case_i, downcase ic before doing
528 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
530 * configure.in: Added configuration option `guile-debug'.
531 Configure with --enable-guile-debug if you want a bunch of extra
532 functions used for debugging when developing Guile.
534 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
536 * procs.c (make-cclo): New undocumented debugging procedure: Make
537 compiled closure with internal procedure PROC and length LENGTH.
538 Only compiled if GUILE_DEBUG is defined.
540 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
542 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
544 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
546 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
547 with 3 or more args internally to the evaluator.
549 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
551 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
552 with 3 or more args internally to the evaluator. This is mainly
553 because we don't want to pass entry and exit points of the
554 debug support twice, but it also seems to increase the speed of
555 the evaluator for such calls (e. g. (+ 1 2 3)).
557 * * backtrace.c (scm_display_application): New procedure:
558 display-application; Set fancy printing parameters individually
559 for different types of display (backtrace, error, application).
560 (These should of course be customizable!)
562 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
563 clear the CHECK-flags.
565 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
567 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
569 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
571 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
572 from pairs with a GLOC in the car.
574 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
575 otherwise `symbol-hash' will behave badly.
576 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
577 we get segmentation fault!
579 * * symbols.c: Added #include "weaks.h". New functions:
580 `builtin-bindings' and `builtin-weak-bindings'. (These will be
581 moved to an extraneous library when we split libguile.)
583 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
585 * filesys.c (scm_stat): stat now takes fport arguments too as
586 documented in the manual.
588 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
590 * debug.c (scm_single_step): Bugfix: Call continuation with
591 scm_call_continuation instead of throwing to it.
593 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
595 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
596 argument wasn't declared to be optional.
598 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
600 * stime.c (scm_init_stime): Add feature "current-time".
602 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
604 * throw.h: prototype for scm_exit_status.
605 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
606 args to derive an exit status. Allows (quit) to work from a
608 (scm_exit_status): new function.
611 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
613 * eval.c (scm_deval): Removed some old code.
614 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
616 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
619 * symbols.c (msymbolize): Bugfix: Must initialize property list to
622 * procs.c: Introduce the existent C function scm_thunk_p at the
623 Scheme level as well.
625 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
627 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
628 used from C to easily lookup the value of a symbol in the current
631 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
633 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
634 scm_init_unif in this file. This will also fix a previous problem
637 * configure.in: Added AM_MAINTAINER_MODE
639 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
641 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
644 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
646 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
647 source files that are not always included in libguile but should
648 have their dependencies calculated by automake. This variable is
649 recognized by automake, no further magic is needed.
650 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
651 to deal exclusively with *.lo files, as it seems. The *.o files
652 are built automatically when the corresponding *.lo file gets
655 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
657 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
660 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
662 * unif.c (scm_array_set_x): minor change to argument error checking.
664 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
666 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
667 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
668 They should only be included in the library at configure.in's
670 (libguile_la_LDADD): Include the appropriate .lo files here.
671 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
672 so we know when to build them (and their .lo bretheren).
673 * configure.in (LIBLOBJS): New substituted variable. We let
674 configure decide which .o files to include in LIBOBJS, and then
675 put the corresponding list of .lo files in LIBLOBJS. The latter
676 is what we pass to libtool.
677 * Makefile.in, configure: regenerated.
679 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
681 * symbols.c (scm_sysintern0): New function. Contains the core of
682 old scm_sysintern but doesn't take a second value argument.
683 (scm_sysintern): Now uses scm_sysintern0.
684 (scm_sysintern_no_module_lookup): Renamed to
685 scm_sysintern0_no_module_lookup and doesn't take a second value
688 * symbols.h (scm_sysintern0: Added declaration.
690 * options.c (scm_init_opts): Use scm_sysintern0 instead of
691 scm_sysintern when interning option keys. Otherwise we risk
692 destroying the values of already interned variables.
694 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
695 scheme-level boolean (use SCM_NFALSEP).
697 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
699 (scm_backtrace): New function. (C version of old function from
700 boot-9.scm) Motivation: Make it possible to display backtraces
701 without depending on boot-9.scm. (I'm uncertain if this
702 motivation is good enough...)
704 * root.h (scm_root_state): Add member the_last_stack_var.
705 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
707 * root.c (mark_root): Mark scm_the_last_stack_var.
709 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
712 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
714 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
715 1. mark_lazy_catch didn't mark the smob.
716 2. Both functions above have standard variants:
717 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
718 free_lazy_catch --> scm_free0.
720 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
722 * throw.c (scm_internal_lazy_catch): New function.
723 (scm_lazy_catch): Rewritten to use it.
724 (scm_ithrow): Handle the new lazy catch representation.
725 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
726 that doesn't have a jmpbuf is a lazy catch clause.
727 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
728 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
729 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
731 (scm_init_throw): Register the new lazy-catch smob type.
732 * throw.h (scm_internal_lazy_catch): decl for new function.
734 * throw.c (scm_internal_catch): Doc fixes.
736 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
737 configure.in. Including this might cause problems if applications
738 that link against libguile include their own copies of alloca, but
739 if they're using autoconf, they should be adding libguile to LIBS
740 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
741 the copy in libguile, and things will be okay. (I think.)
743 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
745 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
747 strop.h: move prototypes too.
749 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
751 * posix.c (scm_init_posix): don't intern EINTR since it's now done
754 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
755 etc. I deleted them from filesys.c long ago, but didn't
756 notice they were here too (although ineffective since
757 sys/stat.h wasn't included).
759 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
761 * eval.c: Don't define alloca in GCC case. gcc will automatically
762 use __builtin_alloca if appropriate.
764 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
766 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
767 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
768 that values of automatic variables are preserved. See comments
769 for safe_setjmp for details.
771 Change from Thomas Morgan:
772 * variable.c: Include eq.h.
773 (var_equal): New function.
774 (variable_smob): Use var_equal as the discriminator for variables.
776 * throw.c (s_throw): Remove extraneous declaration.
778 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
779 * eval.c: Add necessary CPP cruft to support that.
780 * configure, Makefile.in, scmconfig.h.in: regenerated.
782 Change from Thomas Morgan:
783 * procprop.c (scm_procedure_properties): Convert the Scheme
784 boolean returned by scm_procedure_p into a C boolean before using
785 it as a condition for SCM_ASSERT.
786 (scm_procedure_property): Likewise.
788 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
789 indications of Unixness.
792 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
794 * * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
796 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
798 * read.c (scm_lreadr): use scm_misc_error to improve one of the
799 "unknown # object" error messages.
801 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
802 (scm_i_index) and declare it static. Add a 'direction' argument
803 to indicate what way the search should go.
804 (scm_i_index): throw out-of-range error instead of wrong-type-arg
806 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
807 strop.h: remove scm_i_index, scm_i_rindex prototypes.
809 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
811 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
813 * * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
814 to avoid clash with various scsh forks.
816 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
818 The following two changes (ramap.c, throw.c) are motivated by the
819 apparent unportability of forward declarations of static arrays of
820 the form `static foo bar[];'.
822 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
823 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
825 * throw.c (scm_throw): Moved above scm_ithrow.
827 * options.h: Removed the extern declarations of scm_yes_sym and
828 scm_no_sym since these are static.
830 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
832 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
834 * Makefile.am: remove AWK=@AWK@.
835 Add a rule for generating errnos.list.
836 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
838 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
839 don't extract errnos, just set a variable (avoids the
840 need to recompile error.c just because configure is run.)
842 * unif.h: update prototypes.
843 * unif.c (scm_uniform_array_read,write): change the offset and
844 length arguments to start and end, for consistency.
846 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
848 * ioext.h: update prototypes.
849 * * ioext.c (scm_read_delimited_x): replaces scm_read_line and
850 scm_read_line_x, it's a more general procedure using an
851 interface from scsh. read-line and read-line! are now defined
853 * Note that the new read-line trims the terminator
854 by default, previously it was appended to the returned string. An
855 optional argument specifies how to process the terminator (scsh
856 compatible). For the old behaviour: (read-line port 'concat).
857 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
858 returns a pair, but is converted to multiple values if the scsh
861 socket.h: update prototypes.
862 * socket.c (scm_recvfrom): for consistency with other procedures,
863 take start and end as separate optional arguments.
864 * (scm_recv, scm_recvfrom): don't allow the second argument
865 to be a size, only a buffer. Change the scheme names to
866 recv! and recvfrom!. Don't return the buffer.
868 * ioext.h, posix.h: move prototypes too.
869 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
870 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
871 "read.h" and "unif.h".
872 * ioext.c: include "chars.h"
874 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
876 * dynl.c: The dynamic linking and module registration functions
877 are now defined even when dynamic linking is not available for the
878 host system. Some of their functionality can be done without
879 dynamic linking; when it's really needed, they throw errors.
881 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
883 * configure.in: Only define DYNAMIC_LINKING when one of the system
884 dependent functions is detected.
885 * dynl.c (scm_dynamic_func): New function to get the address of a
886 function in a dynamic object.
887 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
888 produced by scm_dynamic_func as the thing to call.
890 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
892 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
893 (scm_register_module_xxx, scm_registered_modules,
894 scm_clear_registered_modules): New functions.
896 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
898 * symbols.c (scm_sysintern): Renamed to
899 scm_sysintern_no_module_lookup.
900 (scm_sysintern): New function to take the place of the old
901 scm_sysintern. It uses the current toplevel lookup closure to give
902 the symbol its value. This is a temporary hack to put packages
903 like gtcltk into their own module.
904 (scm_can_use_top_level_lookup_closure_var): New variable to tell
905 us whether `scm_top_level_lookup_closure_var' has been initialized
907 * eval.c (scm_init_eval): Set it.
909 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
911 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
912 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
914 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
916 * (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
917 scm_sys_dup): deleted: FD capability will be added to other
919 * Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
920 scm_fd_free, fd_smob, scm_intern_fd.
921 * (scm_open): renamed from scm_sys_open. Return a port instead of
922 an FD object. Make the mode argument optional.
923 * (scm_sys_create): deleted, it's just a special case of open.
924 (scm_init_filesys): move interning of constants O_CREAT etc.,
925 here (were previously using SCM_CONST_LONG macro).
926 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
928 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
929 include "fports.h" and <stdio.h>
930 (scm_stat, scm_select): don't support FD objects.
932 * error.h: adjust scm_syserror_msg prototype.
933 * error.c (scm_syserror_msg): take an extra argument for errno.
934 Using the global value didn't always work, since it could be
935 reset by procedure calls in the message or args arguments.
937 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
938 I don't understand why the check was there (and what about the
941 * strop.c (scm_string_copy): allow shared substrings to be copied.
943 * unif.h: corresponding change to prototypes.
944 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
945 recognize two new optional arguments: offset and length. Allow
946 the port argument to be an integer (file descriptor, for scsh).
947 Include <unistd.h> for "read" prototype.
949 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
951 * socket.c: don't include filesys.h.
953 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
955 * Makefile.am: add AWK=@AWK@ (?)
957 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
959 Add a rule to generate errnos.c from errnos.
960 * error.c (scm_init_error): include errnos.c.
961 * errnos_cnvt.awk: new file, converts the list of errno codes to
963 * errnos_get.c: new file.
964 * errnos.default: new file, contains errnos to try if they can't
965 be extracted from errno.h.
966 * configure.in: if using GCC, try and extract errno codes from
970 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
972 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
973 * Makefile.am: Made libguile into a libtool library.
974 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
975 Set libtool_libs to indicate that libguile is a libtool library.
976 See guile/ChangeLog for details.
977 * .cvsignore: ignore "*.lo", the libtool library objects.
979 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
981 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
982 use htons in getservbyport argument.
984 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
986 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
987 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
990 * objprop.c (scm_object_property): No need to take the CDR of the
991 value returned by scm_object_properties, since Aug 20 change.
993 * configure.in: When checking for struct linger, #include
994 <sys/types.h> as well as <sys/socket.h>. I've never known
995 <sys/types.h> to cause any portability problems, and Solaris's
996 <sys/socket.h> needs it.
997 * configure: Rebuilt.
999 I think the Sun compiler has chosen a perverse way to interpret
1000 ANSI declarations combined with K&R definitions. We'll
1001 appease it a little bit. But when it invades France, we fight.
1002 * print.c (scm_iprlist): Change 'tlr' argument to an int.
1003 * print.h (scm_iprlist): Here too.
1004 * numbers.c (scm_divbigdig): Change definition to match
1005 declaration in numbers.h.
1006 * unif.c (scm_makflo): Change definition to match declaration in
1009 * init.c (scm_boot_guile): Don't return the value of
1010 scm_boot_guile_1. This function doesn't return a value;
1011 scm_boot_guile_1 doesn't return a value (or return at all).
1013 * eval.c (unmemocopy): Add a semicolon to appease the Sun
1016 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
1017 compile. I have a feeling this function is a bad idea anyway ---
1018 one should always test for features, not systems.
1020 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
1021 semicolons. Only pure luck kept this from being noticed earlier.
1023 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
1025 * socket.c (scm_recvfrom): Added missing semicolon.
1027 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1029 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
1030 the buffer and start and end positions for scsh networking
1033 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
1035 * configure.in: Revert previous change to this file; the problem
1036 is due to transient automake weirdness.
1037 * configure: Rebuilt.
1039 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
1040 PLUGIN/guile.libs. configure generates the latter from the former.
1041 * Makefile.in: Rebuilt.
1043 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
1044 need this if we install scripts, like guile-snarf.
1045 * configure: Rebuilt.
1047 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1049 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
1051 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
1053 * socket.c (scm_addr_vector): fix faulty scm_listify.
1055 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
1057 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
1058 style block comment is no longer considered an error.
1060 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
1062 * PLUGIN/guile.libs.in: New file.
1063 * PLUGIN/guile.libs: Removed from repository.
1064 * configure.in: Create PLUGIN/guile.libs from
1065 PLUGIN/guile.libs.in. This is for including additonal libraries
1066 needed for dynamic linking.
1067 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
1068 instead of PLUGIN/guile.libs.
1070 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
1072 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
1074 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
1075 occurrences of the given element from the list, not just the
1076 first. This is how the Emacs Lisp functions behave, how the
1077 analogous Common Lisp functions behave, and (I believe) how the
1078 older Maclisp functions worked. I realize that this change may
1079 break code, but it seemed better to break it before the Guile
1082 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
1083 Their prototypes were already present in gc.h, but they weren't
1085 (scm_init_storage): Initialize scm_protects.
1086 * root.c (scm_protects): New element of scm_sys_protects.
1088 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
1090 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1092 * libguile.h: Added #include "libguile/net_db.h".
1094 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
1095 30 change. That file is only meant for communication between the
1096 configuration process and load.c. If code linked against libguile
1097 wants to get at the paths mentioned in libpath.h, it can call
1098 functions declared in load.h.
1100 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1102 * libguile.h: Removed #include "libguile/fdsocket.h"
1104 * net_db.c: Added #include <sys/socket.h>.
1106 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
1108 * filesys.c (scm_input_waiting_p): use select in preference to
1109 FIONREAD, since the latter doesn't detect EOF.
1110 Throw error if neither select nor FIONREAD available.
1112 * socket.c (scm_connect): take a port, not a fd object.
1113 (scm_fill_sockaddr): throw an error if fam is not recognised.
1114 (scm_bind): use scm_fill_sockaddr.
1115 (scm_listen): take a port, not a fd object.
1116 (scm_accept): take and return a port. return #f in the car if
1117 address can't be got
1118 (scm_sock_fd_to_port): new procedure.
1119 (scm_socket): use scm_sock_fd_to_port.
1120 (scm_addr_vector): throw error if unrecognised address type.
1121 take an extra argument with the calling procedure name.
1122 (scm_getsockname): take a port. return #f if address can't be got.
1123 (scm_getpeername): take a port. return #f if address can't be got.
1124 (scm_recvfrom): take a port. return #f for address component if can't
1126 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
1127 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
1129 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
1131 * throw.c (scm_internal_catch): Make body funcs and handler funcs
1132 use separate data pointers, to allow them to be designed
1133 independently and reused.
1134 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
1135 Renamed from catch_body, catch_handler, and uncaught_throw; made
1137 (struct scm_catch_body_data): Renamed from catch_body_data; moved
1139 (scm_catch): Use the above.
1140 (scm_throw): Don't bother printing a message for an uncaught
1141 throw; we establish a default handler in init.
1142 * throw.h (scm_internal_catch): Prototype updated.
1143 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
1145 (struct scm_body_thunk_data): New structure, used as data
1146 argument to scm_body_thunk.
1147 * init.c (struct main_func_closure): New structure, packaging up
1148 the data to pass to the user's main function.
1149 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
1150 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
1151 scm_internal_catch to establish a catch-all handler, using
1152 scm_handle_by_message. This replaces the special-case code in
1154 (invoke_main_func): Body function for scm_internal_catch; invoke
1155 the user's main function, using the main_func_closure pointer to
1156 decide what to pass it.
1157 * root.c (struct cwdr_body_data): Remove handler_proc member.
1158 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
1159 (cwdr_handler): Removed.
1161 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1163 * socket.h (SCM_P): update bind prototype.
1164 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
1165 include "feature.h".
1166 (scm_socket): return a port, not a file descriptor object.
1167 include "fports.h" and <unistd.h>
1168 (scm_bind): take a port, not a file descriptor object.
1169 take an extra argument for address args.
1171 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
1172 INADDR_NONE, INADDR_LOOPBACK.
1174 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1176 * init.c: include net_db.h and not fdsocket.h.
1177 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
1179 * Makefile.am: corresponding changes.
1180 * socket.h: renamed from fdsocket.h, fix names.
1181 * net_db.h: renamed from socket.h, fix names.
1182 * socket.c: renamed from fdsocket.c.
1183 remove _sys from procedure names.
1184 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
1185 add "socket" to features list.
1186 * net_db.c: renamed from socket.c.
1187 remove _sys from procedure names.
1188 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
1189 add "net-db" to features list.
1190 include "net_db.h". don't include <sys/socket.h> or
1193 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1195 * tags.h (scm_tags): Removed comma at end of last enumerator.
1197 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
1199 Don't use GCC extensions to allocate space for debugging frames.
1200 (Here he goes again! Why do we put up with this?!)
1201 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
1202 an scm_debug_info structure, not an in-line array of them. Add
1203 'info' member, to say how many vect elements we've used, for eval
1205 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
1206 a new variable debug_info_end to mark the end of vect, instead of
1207 the address of the 'info' pointer itself.
1208 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
1209 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
1210 (SCM_APPLY): Explicitly allocate space for debug.vect.
1211 * debug.c (scm_m_start_stack): Same, for vframe.vect.
1212 * stacks.c: Adjusted for new debug frame structure.
1213 (RELOC_INFO, RELOC_FRAME): New macros.
1214 (stack_depth, read_frames): Use them, and new scm_debug_frame
1215 element 'info', instead of magically knowing that eval frames have
1216 an info pointer sitting after vect.
1217 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
1219 (scm_init_stacks): Formatting tweaks.
1221 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
1223 Give GCC more control flow information, so it can be sure that
1224 variables aren't used uninitialized.
1225 * error.h (scm_error, scm_syserror, scm_syserror_msg,
1226 scm_sysmissing, scm_num_overflow, scm_out_of_range,
1227 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
1228 scm_misc_error): Tell GCC that these functions never return.
1229 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
1230 out the field type, call abort if SCM_ASSERT returns, to placate
1232 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
1233 scm_wta ever returns. We can't handle this case anyway, and this
1234 gives the optimizer more information.
1235 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
1236 scm_wta ever returns.
1238 In some cases, the code is fine, but GCC isn't smart enough to
1239 figure that out; this usually happens when one variable is only
1240 initialized and used when a particular condition holds true, and
1241 we know that condition will never change within a given invocation
1242 of the function. In this case, we simply initialize the variables
1243 to placate the compiler, hopefully to a value which will cause a
1244 crash if it is ever actually used.
1245 * print.c (scm_iprin1): Initialize mw_pos.
1246 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
1247 * throw.c (scm_ithrow): Initialize dynpair.
1248 * unif.c (scm_uniform_vector_ref): Initialize cra.
1249 * struct.c (init_struct): Initialize prot.
1250 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
1252 * strports.c (scm_eval_0str): Don't return uninitialized garbage
1253 if EXPR contains no expressions.
1255 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
1257 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
1258 cause an infinite loop (???). So much for the algebraic
1259 equivalency of variable-sized arrays and alloca...
1261 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
1263 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
1264 a SCM boolean, not a C boolean.
1266 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
1268 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
1269 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
1270 rules for raising scm_mtrigger. Previously, unfortunate but not
1271 unlikely circumstances could result in almost constant invokation
1272 of the gc. Now, this situations should be less likely, but they
1273 are not prevented completely.
1275 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
1277 * numbers.c (scm_fuck): Procedure removed; looks like old test
1279 * numbers.h: Prototype removed.
1281 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
1283 * debug.h (scm_debug_frame): Change `vect' member from an in-line
1284 array to a pointer, to match my Nov 21 change in eval.c.
1286 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1288 * libguile.h: Added #include "libguile/backtrace.h", #include
1289 "libguile/stacks.h".
1291 * strings.c (scm_string scm_make_string scm_string_ref
1292 scm_string_set_x scm_string_equal_p scm_string_append):
1293 Bugfix according to scm patch from Aubrey Jaffer:
1294 Corrected long-standing
1295 (not (eqv? (integer->char 128)
1296 (string-ref (make-string 1 (integer->char 128)) 0)))
1297 bug found by John Kozak <jk@noontide.demon.co.uk>.
1299 * strports.c, strports.h: Make scm_eval_0str return the value of
1300 the last expression evaluated (previously, it returned void).
1302 * strports.c, strports.h: New function: scm_read_0str. Does what
1305 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1307 * simpos.c (scm_getenv): return #f if string can't be found in the
1308 environment instead of throwing an exception, for compatibility
1309 with numerous other systems.
1311 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
1313 * Makefile.am (.c.x): Use guile-snarf.
1314 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
1316 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
1318 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1320 * backtrace.c (scm_display_error_message): Made non-static, and
1321 renamed from display_error_message.
1322 * backtrace.h (scm_display_error_message): Added extern decl.
1323 * throw.c (uncaught_throw): Use it to display the error message.
1325 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
1327 * inet_aton.c: Use #if 0, not #ifdef 0.
1329 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
1331 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
1332 to convert the returned value.
1333 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
1334 the offset argument.
1336 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1338 Add new interface to catch/throw, usable from C as well as
1340 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
1341 (scm_internal_catch): New function, replaces...
1342 (scm_catch_apply): Deleted.
1343 * throw.c (scm_catch_apply): Deleted; replaced with a more general
1344 mechanism which is a bit more code, but can be used nicely from C
1345 and implement the Scheme semantics as well.
1346 (scm_internal_catch): This is the replacement; it's named after
1347 the analogous function in Emacs.
1348 (scm_catch): Reimplemented in terms of the above.
1349 (struct catch_body_data, catch_body, catch_handler): New
1350 functions, used by scm_catch.
1351 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
1352 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
1353 support for new cwdr.
1355 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
1358 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
1360 * acconfig.h: Added DYNAMIC_LINKING symbol.
1361 * configure.in: Add option and checks for dynamic linking.
1362 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
1363 dynl.h: New files for dynamic linking support.
1364 * Makefile.am (libguile_a_SOURCES):
1366 (modinclude_HEADERS): Added "dynl.h".
1367 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
1369 * init.c (scm_boot_guile_1): Call
1370 scm_init_dynamic_linking to initialize dynamic linking support.
1372 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
1374 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
1375 (as we Schemers say). It needs to be global, so that I can tweak
1376 it for the proper operation of unexec.
1377 (scm_boot_guile_1_live): New variable, see above.
1379 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
1381 * guile-snarf.sh: Removed.
1382 * PLUGIN/guile.libs: Added dependency for -lm.
1383 * acinclude.m4: Renamed from aclocal.m4.
1384 * PLUGIN/greet: Removed.
1385 * Makefile.am, aclocal.m4: New files.
1386 * configure.in: Updated for Automake.
1388 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
1390 * eval.c (scm_definedp): Use top_level_lookup_closure_var
1391 and not top_level_lookup_thunk_var.
1393 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
1395 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
1397 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
1399 * eval.c (scm_definedp): Incompatibly changed to be a builtin
1400 Scheme function, instead of syntax. Single argument is now a
1403 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1405 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
1406 scm_ra_divide): Properly terminate statements passed as arguments
1407 to IVDEP macros. (Thanks to Bernard Urban.)
1409 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
1410 with non-constant sizes. (Thanks to Bernard Urban.)
1412 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1414 It's an "eval closure", not an "eval thunk." A thunk is a
1415 function of no arguments.
1416 * root.h (struct scm_root_state): Renamed
1417 top_level_lookup_closure_var from top_level_lookup_thunk_var.
1418 (scm_top_level_lookup_closure_var): Renamed from
1419 scm_top_level_lookup_thunk_var.
1420 * root.c (mark_root): Uses changed.
1421 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
1422 * init.c (scm_start_stack): Uses changed.
1423 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
1424 Change scheme-visible name to *top-level-lookup-closure* from
1425 *top-level-lookup-thunk*.
1427 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
1429 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
1430 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
1432 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
1434 * gc.c (struct scm_heap_seg_data): Doc fixes.
1436 * gc.c (scm_gc_sweep): Empty all segments' freelists before
1437 sweeping. Then, prepend each segment's free cells to its
1438 freelist, rather than wiping out the old value. (Thanks to Marius
1441 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
1442 scm_check_freelist, scm_debug_newcell): New functions and
1443 variables, for debugging freelist problems.
1444 * pairs.h (SCM_NEWCELL): New debugging version added.
1445 * gc.h (scm_debug_newcell): Added extern declaration, used by
1446 debugging version of SCM_NEWCELL.
1448 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1450 On some systems <libc.h> conflicts with <unistd.h>, and should not
1451 be #included at all.
1452 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
1453 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
1454 * configure.in: Call it.
1455 * posix.c, filesys.c: Use its results to decide whether or not to
1457 * configure, scmconfig.h.in: Rebuilt with autoconf and
1460 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1462 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
1463 pointer to the stdio stream before calling scm_setbuf0, so the
1464 latter will be able to retrieve it. I'm surprised this didn't
1465 segfault earlier. (Thanks to Christopher Lee.)
1467 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1469 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
1472 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1474 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
1475 number of stack narrowing specifier pairs. The first specifier in
1476 a pair controls inner border, the second the outer border. A
1477 number means cut that number of frames, a procedure object means
1478 cut until that object is found in operator position in a frame.
1480 * root.c (cwdr): Bugfix.
1482 * read.c: Recording of positions disabled by default.
1484 * procs.c (scm_closure_p): New function.
1486 * posix.c (scm_tmpnam): New function.
1488 * load.c: Added #include "throw.h".
1489 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
1492 * load.c, load.h (scm_read_and_eval_x): New function.
1494 * eval.c: Renamed debug option "deval" to "debug".
1496 (scm_eval_x): `eval!' is no longer accessible from the scheme
1497 level. Motivation: We can't allow operations which introduce
1498 glocs into the scheme level. Guile's type system can't handle
1499 these as data. Use `eval' or `read-and-eval!' as replacement.
1501 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
1502 SCM_CONSP since this is a macro!; Set vframe.prev to
1503 scm_last_debug_frame instead of 0. In this way we can look
1504 "above" the virtual start stack frame if we wish.
1505 (scm_debug_hang): New function: Useful for debugging Guile in
1506 certain tricky situations. Will probably be removed later...
1508 * debug.h: Changed semantics of debug option "backtrace". This
1509 option now only indicates whether we want automatic backtrace at
1512 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1514 * ports.c: #include "filesys.h"
1515 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
1517 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
1518 Motivation: This is system specific code which is related to file
1519 I/O. It also may use select. Added code by Gary Houston to
1520 detect presence of character in stdio buffers.
1522 * libguile.h: #include "libguile/libpath.h"
1524 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
1525 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
1526 SCM_SITE_DIR; Install libpath.h among the other include files.
1528 * load.c, load.h (scm_sys_package_data_dir): New function.
1530 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1532 * stacks.h: Bugfix: Don't use tail-array length field as stack
1533 length field! This screwed GC.
1535 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1537 * _scm.h: Added #ifndef around definition of macros min and max.
1539 * __scm.h: Added hooks for threads to plugin to in ints protection
1540 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
1541 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
1542 the main code in these macros duplicated and spread over multiple
1543 files. Renamed SCM_THREADS_SWITCHING_CODE ->
1544 SCM_THREAD_SWITCHING_CODE.
1546 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
1548 * snarf.h: New file.
1549 * guile-snarf.sh: New file.
1550 * Makefile.in (inner_h_files): Added snarf.h
1551 (ancillary, install, uninstall, distclean): Added actions for
1553 (.c.x): Use guile-snarf.
1554 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
1555 (gen_c_files): Note that these depend on guile-snarf.
1556 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
1557 now in "snarf.h". Added #include "snarf.h" to get them.
1558 * libguile.h: Added #include "snarf.h".
1559 (Patches applied and tweaked by Jim Blandy.)
1561 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1563 * socket.c: Use K&R style declaration for 'close'; the GNU coding
1564 standards suggest against providing prototypes for system
1565 functions. Thanks to Greg Troxel.
1567 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1569 * strports.c (scm_eval_0str): New function.
1570 #include "read.h", to get prototype for scm_read.
1571 * Makefile.in (strports.o): Update dependencies.
1572 * strports.h: New prototype.
1574 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
1575 scheme name from "int?" to "integer?". It seems to do the job.
1576 * numbers.h: Rename prototype too.
1577 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
1580 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
1581 scm_num_eq_p): Rename these according to R4RS conventions: call
1582 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
1583 to making libguile R4RS compliant without ice-9...
1585 * load.c (scm_sys_search_load_path): Search for files under all
1586 extensions listed in the %load-extensions variable. If FILENAME
1587 is absolute, return it unchanged, without searching the load path.
1588 (scm_loc_load_extensions): New variable, pointing to
1589 %load-extensions' value cell.
1590 (scm_init_load): Initialize it, and the value it points to.
1591 (scm_primitive_load_path): Improve error reporting.
1593 * load.c (scm_loc_load_hook): New variable, pointing to value cell
1594 of new Scheme variable %load-hook.
1595 (scm_primitive_load): Apply %load-hook to filename.
1597 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
1599 * configure.in: add tests for figuring out whether buffered data
1600 is available in a FILE structure, which is needed by char-ready.
1602 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
1605 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
1606 exceptions using misc_error instead of syserror. It seems a bit
1607 odd to throw an exception if a string can't be found in the
1608 environment, but it's consistent with open-file, stat etc.
1609 (simpos.h): remove sys_ from getenv.
1611 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
1612 occurs, throw an error instead of returning errno. Return value
1614 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1616 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1618 * filesys.c (scm_stat2scm): derive file type and permissions from
1619 the stat mode and append them to the returned vector.
1620 There isn't much overhead in doing this and it avoids the need to
1621 work with S_IRUSR et al. in Scheme.
1622 Define symbols scm_sym_regular etc.
1623 (scm_init_filesys): don't intern S_IRUSR etc.
1625 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1626 and s_primitive_load_path.
1628 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1630 * error.h: don't declare error symbols. prototype for scm_misc_error.
1632 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1635 * error.c: use SCM_SYMBOL to set up error keys.
1636 scm_misc_error: new procedure.
1638 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1640 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1641 between `#!' and `!#' is ignored.
1642 (skip_scsh_block_comment): New function.
1644 * feature.c (scm_set_program_arguments): New argument, FIRST.
1645 * feature.h: Update prototype.
1646 * init.c (scm_boot_guile_1): Pass new argument to
1647 scm_set_program_arguments.
1649 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1651 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1652 (scm_boot_guile): Call scm_set_program_arguments here, later than
1653 the old initialization.
1655 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1656 initialization procedure.
1657 - Delete in, out, err arguments; there are other perfectly good
1658 ways to override these when desired.
1659 - Delete result argument; this function shouldn't ever return.
1660 - Rename init_func argument to main_func, for less confusion.
1661 - Delete boot_cmd argument; main_func is more general.
1662 -Add 'closure' argument, to help people pass data to main_func
1663 without resorting to global variables.
1664 - Abort if reentered; don't bother returning an error code.
1665 - Call scm_init_standard_ports to set up the default/current
1666 standard ports; no need to pass them to scm_start_stack.
1667 - Remove code to evaluate the boot_cmd, and start the repl; let
1668 the user do something like that in main_func if they want.
1669 - Remove code to package up a return value; main_func can do any
1671 - Call exit (0), instead of returning.
1672 (scm_start_stack): Don't initialize the I/O ports here; that's
1673 weird. Delete in, out, err arguments. Move guts to
1674 scm_init_standard_ports, scm_stdio_to_port.
1675 (scm_init_standard_ports): New function, to set up current and
1676 default standard ports.
1677 (scm_start_stack, scm_restart_stack): Make these static.
1678 * init.h (scm_boot_guile): Adjust declaration.
1679 (scm_start_stack, scm_restart_stack): Remove externally
1680 visible declarations for these.
1681 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1683 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1684 written out several times in scm_start_stack.
1685 * fports.h: New declaration for the above.
1687 * feature.c (scm_set_program_arguments): New function.
1688 * feature.h: New declaration for the above.
1690 * ports.c: Formatting tweak.
1692 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1694 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1695 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1696 for obtaining the address of a car or cdr field. Motivation:
1697 &SCM_CXR make assumptions about the internal structure of the
1700 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1701 Motivation: see SCM_CXRLOC.
1703 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1704 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1705 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1706 Motivation: Safer use. Some other macros are defined in terms of
1707 these operations. If these are defined using the SCM_SETCXR
1708 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1709 to inefficiency and an <e1> with side-effects could potentially
1710 break. Also, these particular operations are heavily utilized in
1711 the garbage collector. In unoptimized code there will be a
1714 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1715 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
1716 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
1717 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
1718 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
1719 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1720 vports.c: Cleaned up use of pairs: Don't make any special
1721 assumptions about the internal structure of selectors and
1722 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1723 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1724 (Among other things, this change makes it easier to build Guile
1725 with certain compilers which have problems with casted lvalues.)
1727 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1729 * stacks.c: Improve selection of relevant stack frames when making
1730 a stack object. Introduce one level of indirection in the stack
1731 object to make it possible to "narrow" to a certain region of the
1732 stack. This facilitates making use of more clever algorithms (not
1733 implemented) for selecting relevant frames and gives a cleaner
1734 design since selection of frames can be done independently of
1735 extraction of frames from the real stack.
1736 (scm_stack_id): Also take #t as argument which means look at
1739 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1740 Turn n_tail into an integer directly representing current number
1741 of frames in stack. Add field tail.
1743 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1745 * debug.c (scm_make_memoized): Made it available at scheme level.
1746 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1747 SCM_NIMP before applying heavier predicates in argument checking.
1748 (scm_local_eval): Also take memoized object as argument.
1750 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1751 aren't created with zero length, but should such a strange
1752 creature suddenly turn up...
1754 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1756 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1757 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1759 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1761 * variable.c (scm_make_variable): Make the name hint optional, as
1763 (anonymous_variable_sym): Renamed from variable_sym. All uses
1766 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1767 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1768 of scm_primitive_load_path was also changed to
1769 "primitive-load-path", from "%try-load-path". Callers changed.
1770 We'd like to respect the convention that a function named
1771 "try-mumble" should behave just like the function called "mumble",
1772 but return #f instead of signalling some error.
1773 * load.h: Rename prototypes.
1775 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1777 * print.c (make_print_state, grow_print_state), print.h: Modified
1778 the print state representation: Don't use a tail array for
1779 recording of circular references. Resizing of the print state
1780 structure invalidates the print state pointer. To avoid passing
1781 around an indirect print state reference to all printing
1782 functions, we instead let the print state reference a resizable
1785 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1787 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1788 Don't crash when passed an improper list terminated by a
1789 non-immediate value.
1791 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1793 Allocate data for structures on an eight-byte boundary, as
1794 required by the tagging system.
1795 * struct.c (alloc_struct): New function.
1796 (scm_make_struct, scm_make_vtable_vtable): Call it.
1797 * struct.h (scm_struct_n_extra_words): Bump to 3.
1798 (scm_struct_i_ptr): New "field".
1799 * gc.c (scm_gc_sweep): When we need to free the data, use the
1800 information stored by alloc_struct to find the beginning of the
1801 block allocated to the structure, so we can free it.
1803 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1805 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1808 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1809 (scm_debug_info): New member: id.
1811 * stacks.c: Stacks are now represented as structs; Stacks have an
1812 id given to them by `start-stack'.
1813 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1815 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1816 Changed stack representation.
1818 * debug.c (scm_procedure_name): Try procedure property `name' for
1819 compiled closures aswell.
1821 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
1823 * eval.c: scm_i_name moved to gsubr.c
1824 (scm_m_define): Record names of all kinds of procedure
1825 objects. (Earlier, only closures were recorded.)
1827 * procprop.h: Added declaration of scm_i_name.
1829 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1830 (scm_make_gsubr): Record names of compiled closures.
1832 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1834 * debug.c, debug.h: Removed obsolete code.
1836 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1837 stacks.c: Renamed regs --> scm_contregs.
1839 * print.c (scm_free_print_state): Cleanup print state before
1840 returning it to pool. It is better to do it here than in
1841 scm_prin1 since scm_prin1 is called often.
1843 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1844 s_set_source_property_x): Check that first argument is a pair or a
1847 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1848 scm_i_line, scm_i_column and scm_i_breakpoint global.
1850 * init.c: Added #include "backtrace.h" and #include "stacks.h".
1851 (scm_boot_guile_1): Added calls to scm_init_backtrace and
1854 * debug.h: Added debug object smob declaration and macro
1857 * configure.in: Build with backtrace.o and stacks.o if debug
1860 * Makefile.in: Added entries for new files: backtrace.c,
1861 backtrace.h, stacks.c and stacks.h.
1863 * symbols.c (scm_sym2ovcell): Fixed documentation.
1865 * _scm.h (min, max): Added.
1867 * async.c: Moved `min' macro to _scm.h.
1869 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1870 SCM_BACKTRACE_INDENT.
1872 * eval.c: Added new debug options `maxdepth' and `indent'.
1874 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
1876 * print.h: Added selector SCM_PRINT_STATE.
1878 * print.c: New functions: scm_make_print_state,
1879 scm_free_print_state.
1881 * print.h: Added declarations for scm_make_print_state,
1882 scm_free_print_state.
1884 * debug.c (scm_m_start_stack): New acro.
1886 * debug.h: Small cleanup.
1888 * init.c (scm_boot_guile_1): Moved scm_init_debug below
1891 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

1913 declare functions with prototypes. (Patch thanks to Marius
1916 More prototype-related changes from Marius Vollmer:
1917 * gdb_interface.h: Wrapped header file in #ifdef/#endif
1918 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
1919 * ports.h (ptobfuns): Added prototypes. This means some casting in
1921 * fports.c: Added casts for initializations, since the functions
1922 are defined to take FILE * as their stream argument, not SCM.
1923 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
1924 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
1925 to `char *str_data' to conform to prototype.
1927 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1929 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
1931 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
1933 * stime.c, stime.h: use SCM_P method.
1935 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1937 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
1938 be given at least two arguments. Insist that lst's last element
1939 be a list, but don't make any requirements of its predecessors.
1941 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1943 * eval.c (scm_nconc2last): Revert last change; there seems to be
1944 other stuff going on here.
1946 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1948 * eval.c (scm_nconc2last): Make sure that each element of lst
1949 (which is a list of argument lists, except for the tail) is a
1950 proper list, i.e., finite and terminated by '().
1952 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1954 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
1957 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
1958 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
1961 * vectors.c (scm_make_vector): Fill vectors with the undefined
1962 value, to help make Guile Scheme code more portable to other
1965 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
1966 * symbols.h, tags.h: Doc fixes.
1968 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
1970 * async.c (scm_take_signal): Doc fixes.
1972 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
1974 * numbers.c (scm_divbigint): When the remainder is zero, we don't
1975 want to subtract it from the modulus; we just want to leave it
1978 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
1980 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
1983 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
1985 * throw.c (scm_catch_apply): Finished implementation of
1988 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
1990 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
1992 (scm_init_filesys): set "i/o-extensions" feature.
1995 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
1997 * Makefile.in (root.o): Correct dependencies.
1999 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
2001 * Makefile.in: Added dependency entry for root.o.
2003 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
2004 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
2006 * init.c (scm_start_stack): Set initial root continuation number
2009 * procs.c: New function: scm_thunk_p.
2011 * procs.h: Added declarations of scm_thunk_p.
2013 * root.c: Renamed `call-with-new-root' -->
2014 `call-with-dynamic-root'.
2015 (cwdr): Removed allocation of new root state. This should be done
2016 separately by use of scm_make_root.
2017 (scm_apply_with_dynamic_root): New function: Does what it
2018 sounds like. Needed when spawning threads.
2020 * root.h: Added member last_debug_frame to root state.
2021 Added #include "libguile/debug.h"
2023 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
2024 arguments. The motivation is that code in root.c needs catch
2025 functionality, and we want to avoid code duplication.
2026 New functions: scm_catch, scm_lazy_catch. These are wrappers for
2027 scm_catch_apply. scm_lazy_catch is intended to introduce catch
2028 handlers that run without popping the stack into the dynwind
2031 * throw.h: Added prototypes for scm_catch_apply and
2034 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2036 * root.h (scm_root, scm_set_root): Decouple thread support details
2037 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
2038 SCM_SET_THREAD_LOCAL_DATA.
2040 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
2041 and tortoise scanning loop.
2043 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
2045 * Makefile.in: Rebuild dependencies.
2047 * libguile.h: #include "libguile/print.h" before "smob.h", since
2048 the latter uses the print_state structure.
2050 * throw.c (scm_ithrow): Use the correct variable when checking to
2051 see if a given element of scm_dynwinds is a valid catch.
2053 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
2054 structure, abort; don't just silently ignore the garbage.
2056 * _scm.h: #include "print.h" here, since it seems to be used just
2058 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
2059 strports.c, unif.h: Don't #include "print.h".
2061 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2063 * feature.h (scm_loc_features): Removed external declaration.
2064 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
2066 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2068 * feature.c (scm_init_feature): Added threads feature (needs to be
2069 initialized here, since features doesn't exist when
2070 scm_init_threads is called).
2072 * libguile.h: Added #include "libguile/../threads/threads.h".
2073 (This is a kludge to get thread support working. This should be
2076 * configure.in, acconfig.h: Added flags for thread support.
2078 * scmsigs.c: Define `signal' to be `pthread_signal' if using
2081 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
2082 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
2085 * _scm.h: Added conditional #include "threads.h"
2087 * __scm.h (SCM_ASYNC_TICK): Added call to macro
2088 SCM_THREADS_SWITCHING_CODE.
2090 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
2091 allocate the basic dynamic root object.
2092 (scm_boot_guile): Added call to scm_init_root.
2094 * root.c, root.h: Added root smob.
2095 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
2096 functions: Implements dynamic roots mostly according to spec in
2097 SCM manual. Main difference is that the second argument is a
2098 throw handler rather than an error "thunk".
2100 * root.h: Added declaration of scm_init_root.
2102 * root.c: Added #include "genio.h", #include "smob.h", #include
2103 "pairs.h", #include "throw.h", #include "dynwind.h", #include
2105 (scm_init_root): Added #include "root.x".
2107 * throw.c: Added #include "stackchk.h"
2108 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
2109 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
2110 can be used in scm_call_with_new_root; Added reenabling of stack
2111 checking when catching a throw.
2113 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
2115 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
2117 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
2118 element is not found, as per R4RS.
2120 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2122 * list.c: Doc fixes throughout.
2124 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2126 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
2127 declare the char * to be const. Avoids a warning in rgx.c.
2129 * ports.h: spelling fix.
2131 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
2134 * load.c (scm_sys_try_load_path): throw an error if file not found
2135 (like it says it in NEWS).
2137 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2139 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
2140 PROPS slot to '(), not #f; it's an empty alist.
2142 * throw.h, throw.c: Use SCM_P instead of #if hair.
2144 Remove special support for uncaught throws; see throw.c for
2146 * throw.c (uncaught_throw): New function.
2147 (scm_ithrow): Call uncaught_throw if we don't find a throw
2148 target; don't mess with scm_bad_throw_vcell.
2149 (scm_bad_throw_vcell): Variable deleted.
2150 (scm_init_throw): Don't initialize it.
2152 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
2155 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2157 * numbers.c (scm_istr2int): If the number is short (as most
2158 numbers are), just call scm_small_istr2int to deal with it.
2159 (scm_small_istr2int): New function, created by un-#ifdefing the
2160 non-bignum version of scm_istr2int and renaming it.
2162 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
2164 * load.c (scm_sys_try_load): don't check whether value returned
2165 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
2166 Change the Scheme name from %try-load to primitive-load.
2168 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
2169 Can avoid passing a message, allowing it to be derived in the
2170 error handler (e.g., if we want to throw to the key both from
2173 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
2175 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
2176 references now have a new appearance which is more compact and
2177 also gives a clue about what the target of the reference is.
2178 By setting parameters in the print state, more fancy printing can
2179 be achieved. This is used by the (not yet commited) backtrace
2182 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
2184 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
2187 * print.c: Added #include "struct.h". Removed function
2190 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
2191 scm_iprin1. Removed prototype for scm_prlist.
2193 * arbiters.c (prinarb),
2194 async.c (print_async),
2195 debug.c (prindebugobj, prinmemoized),
2196 eval.c (prinprom, prinmacro),
2197 filesys.c (scm_fd_print, scm_dir_print),
2199 mallocs.c (prinmalloc),
2200 numbers.c, numbers.h (scm_floprint, scm_bigprint),
2201 smob.h (scm_smobfuns),
2202 srcprop.c (prinsrcprops),
2204 unif.c, unif.h (scm_raprin1, rapr1),
2205 variable.c (prin_var): Changed argument `int writing' to
2206 `scm_print_state *pstate'.
2208 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
2209 that it will be called before scm_init_print.
2211 * print.c (scm_prin1): Print states are now allocated when calling
2212 scm_prin1 and then passed around to all printing functions as an
2213 argument. A cache `print_state_pool' enables reuse of print
2215 (scm_make_print_state): New function.
2216 (scm_iprin1): Adaption to print states.
2217 (scm_iprlist): An initial "hare and tortoise" scan brings down
2218 time complexity to O (depth * N). (Better time complexity will be
2219 achieved when the printing code is completely rewritten.)
2221 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2223 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
2224 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
2225 it gets done whether or not the cache variable has a value.
2227 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2229 Distinguish #f and ().
2230 * __scm.h: #undef SICP.
2231 * pairs.h (SCM_EOL): Delete this definition, equating it with
2233 * tags.h (SCM_EOL): Give it a new definition here; I think I found
2234 the value it used to have. Doc fixes, too.
2236 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
2238 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
2239 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
2240 Lord's implementation of structs, allowing for tail arrays as
2241 described in the manual. Also fixed some bugs. (Both the interface
2242 and the implementation should be improved.)
2244 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
2246 * print.c, print.h: Closures now print like #<procedure foo (x)>.
2247 People who whish to see the source can do `(print-enable 'source)'.
2248 Removed #ifdef DEBUG_EXTENSIONS.
2250 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2252 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
2253 integer (assuming for now accepting an integer is a good thing).
2255 * error.c, fports.c: replace use of %S in lgh_error args with %s.
2256 %S will be used instead for write'ing arguments.
2258 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
2259 asserts. fix a few other asserts.
2260 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
2261 scm_uniform_vector_ref, scm_array_set_x,
2262 scm_dimensions_to_unform_array): change args in
2263 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
2264 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
2265 scm_substring_fill_x): likewise.
2266 gsubr.c (scm_gsubr_apply): likewise.
2267 eval.c (SCM_APPLY): likewise.
2269 * eval.c (4 places): replace scm_everr with lgh_error or
2272 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
2273 scm_memory_error): new procedures.
2274 scm_everr: deleted. can use scm_wta, dropping first two args.
2275 scm_error: convert NULL subr to SCM_BOOL_F.
2277 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
2280 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
2283 * error.c, error.h: new error keys: scm_arg_type_key,
2284 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
2286 scm_wta: reimplement using lgh_error instead of scm_everr.
2288 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
2290 * gdbint.c: scm_lread now has one more argument.
2292 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
2293 scm_port_\1; Added mutator scm_set_port_filename_x (used when
2294 loading source from non-file ports, which, e. g., happens when
2295 using the Emacs interface).
2297 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
2300 * read.c: Added code for recording of positions of source code
2301 expressions; New functions: recsexpr, scm_lreadrecparen;
2302 _scm_make_srcprops --> scm_make_srcprops
2303 (scm_flush_ws): Removed updating of positions counters. This work
2304 is already done by scm_gen_getc
2306 * read.h: Added prototype for scm_lreadrecparen
2308 * print.c: Added #include "alist.h"
2310 * eval.c: Added #include "hash.h"
2312 * eq.c: Added #include "ramap.h"
2314 * options.c: Documentation fixes.
2316 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
2317 (scm_init_srcprop): Adjusted size of initial source-whash. Name
2318 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
2319 --> scm_make_srcprops
2321 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
2322 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
2323 function calls in the definition of the whash access macros.
2325 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
2327 * init.c (scm_boot_guile): Add level of indirection to
2328 scm_boot_guile_1() to ensure that stack base pointer is properly
2329 initialized. There was no guarantee that variable i was the
2330 highest/lowest variable on stack (i.e. the call frame of
2331 scm_boot_guile was not completely protected from gc).
2333 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
2335 * ports.h (scm_port_table): put back file_name, it will be used to
2336 support debugging. Undo related changes in fports.c, ioext.c,
2339 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2341 * ports.h (scm_port_table): remove file_name member for now, it seems
2343 * fports.c (scm_open_file): don't set file_name in PTAB.
2344 (prinfport): don't use file_name in PTAB.
2345 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
2346 * ports.c (scm_add_to_port_table): don't intialize file_name.
2347 (scm_port_file_name): remove for now.
2348 * gc.c (scm_gc_mark): don't mark PTAB file_name.
2350 * fports.h (scm_mkfile): prototype deleted.
2351 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
2353 * debug.c, unif.c: use scm_out_of_range instead of
2354 wta for range errors (ASSERT still needs work).
2356 * error.c, error.h (scm_out_of_range): new procedure.
2358 * error.c, error.h (scm_out_of_range_key): new key.
2360 * posix.c (scm_sync): #else was missing.
2362 * error.c, error.h: append _key to names scm_num_overflow and
2365 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
2366 of consing an empty list.
2367 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
2368 of macros, saves code and string space.
2369 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
2370 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
2371 lower case. Rename scm_syserror_m to scm_syserror_msg.
2372 error.h: prototypes for new procedures.
2374 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
2376 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
2378 * error.c, error.h: setup scm_num_overflow key.
2380 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
2381 Remove definition of SCM_OVSCM_FLOW.
2383 * fports.c (scm_open_file): use SCM_SYSERROR_M.
2385 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
2386 explicit message and args.
2388 * error.c, error.h, __scm.h: change system_error_sym to
2391 * error.c (system_error_sym): remove leading %% from the Scheme name
2394 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
2396 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2398 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
2399 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
2400 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
2401 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
2402 renamed. (These were introduced by unsupervised name
2405 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2407 * print.c: Added code for detection of circular references during
2408 printing. (init_ref_stack, grow_ref_stack): New functions. Added
2409 a hook for printing of closures (accessible via print options).
2410 This leads to a split of calls to scm_iprin1 into two classes:
2411 elementary print operations (e. g. the code which prints a smob)
2412 still use scm_iprin1 while top level calls (like scm_display) use
2413 scm_prin1. scm_prin1 begins by clearing the data structure used
2414 to record reference information.
2416 * print.h: Added declarations of scm_prin1 and scm_prlist.
2418 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
2420 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
2422 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
2424 * error.c (err_head): scm_iprin1 --> scm_prin1
2426 * debug.c: Adjusted header comment.
2430 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2432 * strerror.c: Doc fix.
2434 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2436 * gdbint.c (gdb_read): Now possible to run during GC.
2437 (unmark_port, remark_port): New functions.
2439 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
2441 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
2442 of allocating a new string object. Also, increase size by
2443 the factor 2 instead of 1.5.
2445 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
2447 * __scm.h (SCM_P): Corrected to run under traditional C.
2449 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
2452 * async.c: Calls to scm_sysintern corrected.
2454 * async.h (scm_async_clock): Redundant declaration removed.
2456 * continuations.c (scm_dynthrow): Redundant declaration removed.
2458 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
2459 Definition typos corrected.
2461 * debug.h: Missing declarations of functions in debug.c added
2464 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2465 Missing declarations to functions in eval.c added.
2467 * filesys.c: Possibly uninitialized variable rv.
2469 * gc.h (scm_object_addr, scm_unhash_name): Missing
2470 declarations of functions defined in gc.c added.
2472 * genio.c: Possible typos str_data -> wstr_data. ???
2474 * genio.c: Possibly unintended shadowing of local variable
2475 `int c' (gotos out of scope of inner `c'). ???
2477 * init.c: Uninitialized `SCM last' may be used.
2479 * ioext.h: (scm_sys_isatty_p): Typo.
2481 * list.h (scm_list_head): Missing prototype for function in
2484 * numbers.c (scm_two_doubles): Changed from extern to static
2485 (is used only within numbers.c).
2487 * numbers.h: Repeated declarations removed.
2489 * ports.h (scm_close_all_ports_except): Declaration for the
2490 function defined in ports.c added.
2492 * posix.h: Missing declarations added.
2494 * procs.h (scm_make_subr_opt): Missing declaration added.
2496 * socket.h (scm_sys_gethost): Missing declaration added.
2498 * socket.h: Redundant declarations removed (they are in fdsocket.h).
2500 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
2501 Missing declarations added.
2503 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
2505 * struct.c: Uninitialized variable `SCM answer' may be used.
2507 * unif.c (l2ra): Declaration prototype.
2509 * unif.c (scm_array_equal_p): Dummy definition removed (it is
2510 defined in ramap.c).
2512 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
2513 Redundant declarations removed (they are in ramap.h).
2515 * variable.h (scm_make_udvariable,
2516 scm_make_undefined_variable): Declaration corrected to
2517 correspond variable.c.
2519 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
2520 Missing declarations added.
2522 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
2524 * Makefile.in (distclean): Don't forget to delete fd.h.
2526 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2528 * fd.h.in, tags.h: Trivial cleanups.
2530 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
2531 marksweep.h just declared functions from gc.c.
2532 * gc.h, libguile.h: Don't #include "marksweep.h".
2533 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2534 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
2535 dependencies updated.
2537 * libguile.h: Don't #include "files.h"; it's been deleted.
2539 * files.c (scm_sys_delete_file): Moved to filesys.c.
2540 File is now empty; deleted.
2542 * filesys.c: scm_sys_delete_file is now here. Remove
2543 #if's; they seem to rely on remnants of an old portability
2544 regimen. If the problems come up again, solve them properly,
2545 using autoconf. Specifically: Don't test M_SYSV, and #define
2546 remove to be unlink if it's #defined; don't use remove just
2547 because HAVE_STDC_HEADERS is #defined.
2548 * filesys.h: Add declarations for scm_sys_delete_file.
2549 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2550 files.o, files.h, files.c, and files.x.
2551 * init.c: Don't #include "files.h", and don't call scm_init_files.
2553 Use SCM_P instead of PROTO; the latter intrudes on the user's
2555 * params.h: Deleted; definition of SCM_P moved to...
2556 * __scm.h: ... here, where it replaces PROTO macro.
2557 * libguile.h, smob.h: Don't #include "params.h".
2558 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
2559 smob.h: Fix prototypes accordingly.
2560 * Makefile.in: Update dependencies.
2561 (inner_h_files): Remove params.h.
2563 * gc.c: #include "gc.h"; every module should include its header,
2564 to let the compiler cross-check the declarations against the
2567 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2568 simpos.h: #include "libguile/__scm.h".
2570 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2572 * init.c: Don't forget to #include smob.h and init.h.
2573 * Makefile.in: Dependencies updated.
2575 * smob.h: Use PROTO instead of #if __STDC__.
2577 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2579 * __scm.h: Doc fixes.
2581 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2582 <angles>; this allows `make depends' to work properly.
2584 * libguile.h: #include smob.h and pairs.h before the others; they
2585 define typedefs used by other headers.
2587 C files should #include only the header files they need, not
2588 libguile.h (which #includes all the header files); the pointless
2589 recompilation was wasting my time.
2590 * Makefile.in (all .o dependency lists): Regenerated.
2591 * libguile.h: Don't try to get a definition for size_t here...
2592 * __scm.h: Do it here.
2593 * _scm.h: Since this is the internal libguile header, put things
2594 here that all (or a majority) of the libguile files will want.
2595 Don't #include <libguile.h> here; that generates dependencies on
2596 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2597 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2598 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

2623 * fports.c: Get "fports.h", "markers.h".
2624 * gc.c: Get "async.h", "unif.h", "smob.h", "weaks.h",

2634 "unif.h", "throw.h", "tag.h", "symbols.h", "struct.h",

2695 * weaks.c: Get "weaks.h".
2697 * stackchk.h: #include "libguile/debug.h",
2699 * print.h, read.h: #include "options.h", since everyone who uses
2700 either of these files will need that.
2702 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2703 anyone who uses this file will need them to define the smob
2704 printing functions. Also, get markers.h, since people will need
2705 to #define the mark functions.
2707 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2708 * ports.h: ... to here.
2710 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2711 don't rely on archaic C default type rules.
2713 * fports.h: #include "libguile/ports.h", since you need that in
2714 order to parse this.
2716 * genio.h: #include "libguile/print.h", because you need that to
2717 parse this; don't bother #including "ports.h", since print.h gets
2720 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2722 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2723 this; it's now a reference to an element of *scm_root.
2725 * debug.h: Don't #include "options.h"; the compiler won't be able
2726 to find that once the headers are installed; instead, #include
2727 "libguile/options.h".
2728 * gc.h: Same, with marksweep.h.
2729 * mbstrings.h: Same, with symbols.h.
2730 * scmhob.h: Same, with _scm.h.
2731 * smob.h: Same, with params.h.
2733 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2734 C files; there's no need for this, and it forces recompilations
2737 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2739 * error.c (scm_error): declare scm_error_callback.
2741 * error.h: prototype for scm_error_callback.
2743 * __scm.h: define lgh_error.
2744 (SCM_SYSERROR): redefine using lgh_error.
2746 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2748 * error.c (scm_error): new procedure.
2750 * error.h: prototype for scm_error.
2752 * Makefile.in (install): install scmconfig.h from the current
2753 directory, not $(srcdir).
2755 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2757 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2758 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2759 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
2760 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
2761 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
2762 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2763 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2764 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2765 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2766 vports.h, weaks.h: #include "libguile/__scm.h", not
2767 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2768 dependencies are within libguile properly.
2770 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2772 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2773 when scmconfig.h doesn't exist.
2775 * load.c (scm_sys_try_load): Correct spelling.
2777 * feature.c (scm_loc_features): Make this static.
2779 * Makefile.in (libpath.h): Omit trailing slash from path. We
2780 shouldn't require it of users, so why put it here?
2782 Move code to initialize and search %load-path from ice-9 to C
2783 code, so we can use the load-path to find the ice-9 boot code;
2784 this makes it easier to run Guile without installing it. See
2785 corresponding changes in guile/Makefile.in.
2786 * feature.c: Move stuff concerned with the load path to load.c.
2787 (scm_compiled_library_path): Deleted.
2788 Don't #include libpath.h here.
2789 * feature.h: Don't mention scm_compiled_library_path.
2790 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2791 <sys/stat.h>, and <unistd.h> (if present).
2792 (R_OK): #define if the system hasn't deigned to.
2793 (scm_loc_load_path): New variable.
2794 (scm_init_load_path, scm_sys_search_load_path,
2795 scm_sys_try_load_path): New functions.
2796 (scm_init_load): Initialize scm_loc_load_path to point to the
2797 value cell of the Scheme %load-path variable.
2798 * load.h: Add declarations for scm_sys_search_load_path,
2799 scm_sys_try_load_path.
2800 * init.c: Call scm_init_load_path.
2801 * Makefile.in (feature.o, load.o): Dependencies updated.
2803 * load.c, load.h: Rewrite using PROTO macro.
2805 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2807 * gc.c (scm_cellp): New function: C predicate to determine if an
2808 SCM value can be regarded as a pointer to a cell on the heap.
2810 * gc.h: Added declaration of scm_cellp.
2812 * gdb_interface.h: New file: The GDB interface header from the GDB
2815 * gdbint.c: New file: GDB interface.
2817 * gdbint.h: New file: GDB interface.
2819 * libguile.h: Added #include <libguile/gdbint.h>.
2821 * init.c (scm_boot_guile): Added scm_init_gdbint.
2823 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2824 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2825 found if object files and source are kept separate).
2827 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2829 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2831 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2833 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2834 TK_SRC_DIR; they're not relevant any more.
2836 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2837 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2839 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2841 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2842 search path, so we can find the <libguile/MUMBLE.h> headers.
2844 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2846 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2847 implicit in the .c.o rule.
2848 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2851 Put the library path in a header file, instead of passing it on
2852 the command line in every compilation.
2853 * Makefile.in (libpath.h): New target.
2854 (feature.o): Depend on libpath.h.
2855 (clean): Delete libpath.h.
2856 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2857 * feature.c: ... #include "libpath.h" here.
2858 * .cvsignore: Ignore libpath.h.
2860 Don't install the unwashed masses of Guile header files in the
2861 main #include path; put most of them in a subdirectory called
2862 'libguile'. This avoids naming conflicts between Guile header
2863 files and system header files (of which there were a few).
2864 * Makefile.in (pkgincludedir): Deleted.
2865 (innerincludedir): New variable; this and $(includedir) are enough.
2866 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
2867 (installed_h_files): Divide this up. Now this variable lists
2868 those header files which should go into $(includedir) (i.e. appear
2869 directly in the #include path), and ...
2870 (inner_h_files): ... this new variable says which files appear in
2871 a subdirectory, and are referred to as <libguile/mumble.h>.
2872 (h_files): List them both.
2873 (install): Create innerincludedir, not pkgincludedir. Put
2874 the installed_h_files and inner_h_files in their proper places.
2875 (uninstall): Corresponding changes.
2876 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2877 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2878 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
2879 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
2880 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
2881 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2882 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2883 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2884 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2885 vports.h, weaks.h: Find __scm.h in its new location.
2886 * __scm.h: Find scmconfig.h and tags.h in their new locations
2887 (they're both "inner" files).
2889 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
2891 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
2893 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2895 * posix.c: Doc fixes.
2897 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
2899 * socket.c: Don't include a prototype for inet_aton; just use a
2900 K&R style declaration, to avoid warnings but minimize the chance
2901 of conflicts with the system.
2903 On NextStep, <utime.h> doesn't define struct utime, unless we
2904 #define _POSIX_SOURCE before #including it.
2905 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
2906 * acconfig.h: New comment text for above CPP symbol.
2907 * configure.in: Call it.
2908 * posix.c: #define _POSIX_SOURCE if it seems necessary.
2910 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
2912 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
2913 testing for __EMX__.
2915 * posix.c: #include <libc.h>, if it exists.
2917 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
2918 don't even know if the latter exists.
2920 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
2921 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
2922 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
2924 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
2926 (scm_init_posix): Use them when initializing the Scheme constants
2929 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2931 * Makefile.in (libdir, includedir, bindir): Use the
2932 autoconf-supplied values, instead of deriving them ourselves.
2933 (pkgincludedir, datadir, pkgdatadir): New variables.
2934 (install, uninstall): Put the header files in a special
2935 subdirectory, not in the main search path.
2937 * Makefile.in (ALL_CFLAGS): Provide the proper value for
2938 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
2940 * Makefile.in (IMPLPATH): Deleted; never used.
2942 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
2943 on the Tcl/Tk source any more.
2944 (INCLUDE_CFLAGS): Remove references to the above.
2946 * Makefile.in (version.o): Corrected dependencies.
2948 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
2950 * libguile.h: #include "version.h"
2952 * init.c (scm_boot_guile): Call scm_init_version.
2953 * gscm.c (gscm_run_scm): Call scm_init_version.
2955 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
2956 GUILE_VERSION): AC_DEFINE these.
2957 (acconfig.h): #undef the above symbols.
2959 * Makefile.in (libobjs): Add version.o.
2960 (installed_h_files): Add version.h.
2961 (c_files): Add version.c.
2962 (gen_c_files): Add version.x.
2963 (version.o): New rule.
2964 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
2965 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
2966 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,

2968 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
2969 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
2970 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
2971 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,

2973 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
2974 weaks.o): Add version.h to dependency lists.
2975 (markers.o): Remove duplicate rule.
2977 * version.h: New file.
2979 * version.c: New file.
2981 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2983 * symbols.c (scm_strhash): scm_downcase is now a function, not an
2984 array; use it appropriately. Since GCC is quite happy to
2985 subscript functions, it never warned us about this; we should use
2986 -Wpointer-arith in the future. I guess we never tested
2989 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2991 * socket.c: Doc and copyright fixes.
2993 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2995 * debug.c: Fixed and improved gdb support.
2997 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2999 * socket.c: Added declaration of inet_aton to avoid compiler
3000 warning. (Hope this solution is correct.)
3002 * stime.c: Added declaration of ftime. (This is missing in
3005 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
3007 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3009 * Makefile.in (c_files): add strerror.c.
3011 * strerror.c: new file from Emacs' sysdep.c.
3012 maybe configure should also check for sys_errlist.
3014 * configure.in (AC_REPLACE_FUNCS): add strerror.
3016 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3018 * debug.c (scm_init_debug): Added initialization for
3019 scm_evaluator_traps.
3021 * debug.h, debug.c: Various name changes.
3022 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
3023 "debug-options-interface". See commentary in options.c.
3025 * options.h, options.c: Options now have documentation strings.
3026 Also added a long explanatory commentary.
3028 * eval.c, print.h, print.c, read.h, read.c: Modifications to
3031 * gscm.c, init.c, root.c, throw.c: Bug fixes:
3032 last_debug_info_frame is now updated in all cases.
3034 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
3037 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3039 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
3040 Added option STACK_CHECKING.
3042 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3044 * Makefile.in: Added {debug,options,srcprop}.{h,c}
3046 * __scm.h: Removed symbols for debugging support.
3048 * acconfig.h: Added symbols for debugging support.
3050 * configure.in: Added user option for debugging support.
3051 --enable-debug will include the debugging code into libguile.a.
3053 * continuations.c (scm_make_cont): Enlarged the #if 0 around
3054 scm_relocate_chunk_to_heap.
3056 * debug.c: New file: low-level debugging support. It also
3057 includes support for debugging with gdb. (The extensions to gdb
3058 are written by Per Bothner at Cygnus.)
3060 * debug.h: New file: low-level debugging support.
3062 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
3063 argument pairs. Extensive modifications to the debugging
3064 evaluator. Added "SECTION:" commentaries to clarify what happens
3065 when, during double compilation. Renamed EVALIMP --> EVALIM.
3066 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
3067 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
3068 the beginning of the file. New procedure: scm_unmemocopy.
3069 Added some global state variables needed by the debugging
3070 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
3071 check_entry, check_apply, check_exit, debug_options and
3072 evaluator_traps. New acro: undefine.
3074 * eval.h: Renamed EVAL --> XEVAL.
3076 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
3077 --> scm_make_weak_key_hash_table.
3079 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
3080 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
3082 * libguile.h: Conditionally include debug.h
3084 * objprop.c (scm_object_properties, scm_set_object_properties_x):
3085 scm_object_properties shouldn't return handle. `handle' now gets
3086 initialized in scm_set_object_properties_x. scm_object_properties
3087 doesn't any longer create an entry in scm_object_whash.
3089 * options.c: New file: handling of run time options.
3091 * options.h: New file: handling of run time options.
3093 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
3095 * print.c: New procedure: scm_print_options
3097 * print.h: Defines for print options.
3099 * read.c: New procedure: scm_read_options
3101 * read.h: Defines for reader options.
3103 * root.h: Added scm_source_whash among scm_sys_protects.
3105 * srcprop.c: New file: source properties.
3107 * srcprop.h: New file: source properties.
3109 * throw.c (jbsmob): Jump buffers are now correctly allocated.
3110 (Bug found by A. Green.)
3112 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3114 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3116 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
3118 * libguile.h: #include "objprop.h"; I guess this was forgotten.
3120 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
3121 and should be called by the final client.
3123 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
3125 * gc.h: Use the PROTO macro when declaring functions.
3126 * gc.c: Use the PROTO macro when declaring static functions.
3127 Remove the CPP hair around function definitions.
3129 * gc.c (scm_init_storage): Initialize scm_asyncs.
3131 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
3132 preprocessor symbol; "__scm.h" is where it might get #defined.
3133 * __scm.h: Similar: #include <scmconfig.h> before testing
3136 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
3138 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
3140 * init.c (scm_boot_guile): Add init_func argument; call
3141 (*init_func) instead of calling scm_appinit; it's ucky to
3142 hard-code names for the user's procedures.
3143 * init.h (scm_boot_guile): Adjust declaration.
3145 * __scm.h (PROTO): New macro, for declaring functions with
3148 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
3149 eliminate all the __STDC__ conditionals.
3150 (scm_boot_guile): Add declaration.
3151 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
3152 Remove __STDC__ conditionals around function definitions; the
3153 declarations in init.h will provide the same information, more
3156 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
3157 complain about it in the error message; the error message is
3158 adequate without that note, and there's nothing the user can do
3161 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
3163 * Makefile.in (ancillary): Drop def.sed.
3165 * posix.c (scm_init_posix): Use numeric values, rather than
3166 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
3167 F_OK. The symbols aren't available on some systems, and I'm
3168 pretty sure their values are fixed by common widespread practice.
3169 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
3171 More functions unavailable on some systems.
3172 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
3173 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
3175 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3176 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
3177 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
3178 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
3179 stub that signals an error as the #else.
3181 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
3183 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
3185 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
3187 * unif.c: include ramap.h.
3189 * read.c (endif): case_insensative_p renamed case_insensitive_p.
3191 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
3193 * ports.c: include sys/ioctl.h.
3195 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
3197 * configure.in: check for sys/ioctl.h.
3199 * ports.c: include <malloc.h> not "malloc.h".
3201 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3203 * fports.c: remove ttyname and tmpnam declarations.
3205 * posix.c: fewer ttyname declarations.
3207 * fports.c: include <string.h> not "string.h".
3209 * init.c, ioext.c: include string.h and unistd.h.
3211 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3213 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
3214 genio.c, simpos.c, vports.c: include string.h.
3216 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
3218 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
3220 (scm_addr_buffer_size): change type from scm_sizet to int.
3221 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
3222 from scm_sizet to int.
3224 * error.c: include unistd.h.
3226 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
3229 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
3231 * __scm.hd, def.sed: deleted.
3233 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
3235 Changes for NeXT, suggested by Robert Brown.
3236 * configure.in: Call AC_TYPE_MODE_T.
3237 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
3238 NeXT. Put header file list in alphabetical order.
3239 * configure, scmconfig.h.in: Regenerated.
3240 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
3242 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
3245 * acconfig.h: New file, providing documentation for the CPP
3246 symbols defined in configure.in
3247 * acconfig-1.5.h: Removed; superceded by the above.
3249 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
3251 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
3253 * fports.c (scm_open_file): don't return #f, throw error.
3255 * ioext.c (fileno): renamed from %fileno.
3256 (soft-fileno): deleted.
3258 * ports.c (scm_port_revealed): don't need to check for -1 from
3260 (scm_set_port_revealed_x): return unspecified, not #f.
3262 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
3264 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
3266 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
3268 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
3270 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3272 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
3273 This is necessary on Ultrix, and doesn't hurt portability.
3275 * Makefile.in (dist-dir): New target, implementing a new dist system.
3276 (installed_h_files): Put in alphabetical order.
3277 Remove duplicate entries for markers.h and unif.h.
3278 (c_files): Remove duplicate entries for markers.c.
3279 (ancillary): Renamed from anillery; all uses changed. Remove
3280 PLUGIN; it's a directory, and needs special treatment in dist-dir.
3281 Remove all the ../doc/* files; doc/Makefile.in handles that.
3283 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
3285 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
3286 every if must have an else, or else the whole command has a
3287 non-zero exit code whenever the if's condition is false.
3289 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
3291 * posix.c: include string.h.
3293 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
3295 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
3298 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
3299 Remove leading % from scheme names.
3300 Do not return error values, call SCM_SYSERROR or similar.
3302 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
3304 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
3306 * struct.c (scm_init_struct): new file.
3308 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
3310 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
3311 (scm_list_head): added list-head for rapidly chopping argument
3312 lists off of longer lists (and similar).
3314 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
3316 * objprop.c (scm_object_property): assq the cdr of the whash
3317 handle for obj, not the handle itself.
3319 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
3321 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
3322 weak hash tables last of all marking to avoid an obscure gc bug.
3323 WARNING: circular lists stored in a weak hash table will hose us.
3325 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
3327 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
3328 new functions similar to scm_substring_move_left_x and
3329 scm_substring_move_right_x.
3331 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
3333 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
3336 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
3338 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
3340 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
3342 * strports.c (scm_strprint_obj): convenience function. C for
3343 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
3345 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
3346 removed to a separate library
3348 * init.c (scm_boot_guile): copied from guile-tcl.c.
3349 Initialization specific to tcl interpreters removed.
3351 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
3353 * ports.c (scm_ports_prehistory): size malloced here doesn't
3354 matter so long as it is non-0 (got rid of "* 4").
3356 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
3358 * gscm.h: gscm_mkarray eliminated (presumably was not being used
3359 since its definition was bogus).
3361 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
3363 * mallocs.[ch]: back again (for rx at least).
3365 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
3367 * ports.c: removed functions relating to the mapping between ports
3368 and descriptors. (That stuff is unix-specific and should be collected
3369 in a separate library).
3371 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
3372 (Tom Mckay@avanticorp.com)
3374 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
3376 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
3377 handled correctly (SCM_FREEP was applied to them) -- test for

3546 initialization to fix a race condition.
3548 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
