1 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3 * ioext.c (scm_setfileno): add missing third argument to
6 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
8 * eq.c (scm_equal_p): Correctly compare strings of different
9 varieties. (Thanks to Tim Pierce.)
11 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
13 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
14 #! block comment must occur on a line all by itself.
16 Move most of the guts of shell command processing into libguile,
17 so guile.c can be very small (and eventuallly auto-generated. (I
18 mean, generated mechanically, not self-generated. Hmm.))
19 * guile.c, script.c, script.h: New source files.
20 * init.c (scm_boot_guile_1): Call scm_init_script.
21 * libguile.h: #include "script.h".
22 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
23 targets, for new executable.
24 (libguile_la_SOURCES): Mention script.c.
25 (modinclude_HEADERS): Add script.h.
26 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
27 not dynamic linking is enabled. This is because we're generating
28 executables now. Move CY_AC_WITH_THREADS call after those, so the
29 values of cy_cv_threads_libs captures the libs chosen above.
30 * Makefile.in, configure, aclocal.m4: Regenerated.
32 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
33 We don't maintain this interface any more, and it just confuses
36 * alloca.c: #include <scmconfig.h>, not <config.h>.
37 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
38 it'll get included in disties.
40 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
42 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
43 be distributed, because they confuse people.
44 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
46 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
48 * configure.in: check for presence of gethostent (not present on
50 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
51 * configure, scmconfig.h.in: Regenerated.
53 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
55 * backtrace.c (scm_backtrace): Split message string across
56 newlines properly. GCC is more tolerant of this than other

68 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
69 coop-threads.c.cygnus, coop-threads.h.cygnus.
70 * configure.in: If we're using threads, include threads.o in
72 * _scm.h, libguile.h: threads.h lives in this directory now.
73 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
74 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
75 currently used, but brought along for information's sake.
76 * ChangeLog-threads: log from old 'threads' directory.
77 * Makefile.in, configure: Rebuilt.
79 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
81 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
84 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
86 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
88 Merge GH interface library into libguile.
89 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
90 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
91 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
92 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
94 (EXTRA_libguile_la_SOURCES): ... here.
95 (pkginclude_HEADERS): Add variable, to get gh.h installed.
96 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
97 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
98 New variables, describing how to build the gh test programs.
99 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
100 build the test programs, and we probably should have been linking
101 libguile.la against them all along, to support AIX shared libs.
102 Add cflags for threads to CFLAGS; add libs for threads to new
103 variable THREAD_LIBS, used in Makefile.am.
104 * ChangeLog-gh: log from old `gh' subdirectory.
105 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
107 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
109 * acconfig.h: Undo change of Apr 9; including the definition of
110 PACKAGE in the guile headers conflicts with applications' own
112 * scmconfig.h.in: Regenerated.
114 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

121 when PROC is receiving no arguments.
123 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
125 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
126 have S_IFSOCK. This is the case under Ultrix.
128 * posix.c (scm_status_exit_val, scm_status_exit_val,
129 scm_status_term_sig, scm_status_stop_sig): Modified to work with
130 Ultrix versions of WIFSTOPPED, etc., which assume that their
131 arguments are lvalues (hmm).
133 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
137 * throw.c: Doc fixes; rearranged.
139 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
141 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
143 * acconfig.h: Added entry for PACKAGE.
144 * scmconfig.h.in: Regenerated.
146 Changes to work with automake-1.1n, which has better libtool support.
147 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
148 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
150 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
152 * Makefile.in: Rebuild.
154 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
156 * stime.c (scm_mktime): take an optional zone argument.
157 (scm_localtime): check putenv return value.
158 (scm_strftime, scm_strptime): moved from posix.c. move #include
160 stime.h, posix.h: update prototypes.
161 (bdtime2c, setzone, restorezone): new static procedures.
162 (scm_mktime, scm_strftime): use them.
163 (scm_strftime): don't call mktime before strftime. Use
164 filltime for return value.
165 (filltime): convert NULL zname to #f.
166 * (scm_strptime): return a count of characters consumed, not
167 the remaining string.
169 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
171 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
172 (scm_mktime): likewise.
174 Uncomment localtime and mktime.
176 * configure.in: add AC_STRUCT_TIMEZONE.
178 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
180 * stime.c (scm_init_stime): don't define ticks/sec.
181 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
182 return value problem and is still portable.)
184 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
186 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
187 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
188 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
189 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
190 cpp_err_symbols.c): Corresponding changes.
191 * Makefile.in: Regenerated.
193 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
195 * posix.c (scm_putenv): don't check HAVE_PUTENV.
196 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
197 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
198 * putenv.c: new file, from sh-utils 1.12.
200 * posix.c (scm_environ): use malloc in place of scm_must_malloc
201 since allocation isn't for Scheme objects.
202 (scm_putenv): copy strings before placing in the environment.
204 * stime.c (scm_current_time): throw an error if time returns -1,
205 instead of returning #f.
206 (scm_get_internal_real_time, scm_get_internal_real_time): use
207 scm_long2num for return value instead of SCM_MAKINUM.
209 * stime.h: prototypes updated.
211 * stime.c (scm_time_in_msec): apparently unused, deleted.
213 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
215 * configure.in: check for gettimeofday.
217 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
218 which may be more usefully portable than a gettimeofday interface.
220 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
222 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
224 * Makefile.in: Regenerated.
226 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
228 * stime.c (filltime): recovered static procedure.
229 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
232 * posix.h: add prototype for scm_close_pipe, remove prototypes for
233 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
235 * * posix.c (scm_mknod): split the mode argument into type and perms
236 arguments, like the extra fields returned by stat.
238 * fports.c (scm_pipob): set the close, free and print procedures.
239 (scm_close_pipe): new procedure.
241 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
242 define them in boot-9.scm
244 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
246 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
247 wan't defined. Don't include fd.h.
249 * Previously fd.h was regenerated whenever configure was run,
250 forcing a couple of files to be recompiled.
252 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
253 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
254 Check for _fileno as well as _file.
256 * ioext.c: don't fd.h.
257 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
260 * Change the stratigy for getting information about errno
261 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
262 generating lists of symbols during the build process, which will
263 not always work, include comprehensive lists in the distribution.
264 To help keep the lists up to date, the "check_signals" and
265 "check_errnos" make targets can be used.
267 * configure.in: don't check for a command to extract errno codes.
268 * Makefile.am: update file lists, remove errnos.list and errnos.c
269 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
270 check_errnos targets.
271 (CLEANFILES): remove errnos.c and errnos.list, add
272 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
273 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
274 * errnos.default: deleted.
275 * cpp_signal.c: new file.
276 * cpp_errno.c: renamed from errnos_get.c.
277 * cpp_err_symbols, cpp_sig_symbols: new files.
278 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
279 * error.c (scm_init_error): #include cpp_err_symbols instead of
281 * posix.c (scm_init_posix): don't intern signal symbols. #include
284 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
286 * strop.c (scm_i_index): allow the lower bound to be equal to the
287 length of the string, so a null string doesn't always give an error.
289 * posix.h: new prototypes.
290 * posix.c (scm_status_exit_val, scm_status_term_sig,
291 scm_status_stop_sig): new functions, as in scsh. They break down
292 process status values as returned by waitpid.
294 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
296 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
297 configure doesn't know about it.
299 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
301 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
303 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
304 which defines C variables with global linkage.
306 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
308 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
311 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
313 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
314 has time to check why this doesn't work well with continuations.
316 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
318 * Fix shell syntax error; some shells won't tolerate
319 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
321 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
323 * posix.c (scm_uname): throw an error if uname fails instead
326 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
328 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
331 * async.c (scm_ints_disabled): definition moved from error.c.
333 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
335 * acconfig.h: Removed PACKAGE.
337 * scmconfig.h.in: Regenerated.
339 * snarf.h: g++ says it's non-portable not to specify the first
340 argument in a varargs declaration. I introduced the first
341 argument by using preprocessor conditionals.
343 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
345 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
346 (scm_freopen): use RO string macros for filename and modes.
347 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
349 * posix.c (scm_getgrgid): simplify conversion of name to C string.
350 (scm_mknod): use RO string macros for path.
352 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
353 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
355 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
356 use SCM_ROSTRINGP and SCM_ROCHARS.
358 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
360 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
363 * ramap.c (scm_ra_matchp, scm_ra_matchp, scm_array_fill_int, racp,
364 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
365 support for byte vectors.
367 * print.c (scm_iprin1): Limit number of vector elements printed
368 according to pstate->length.
370 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>

375 * error.h: prototype for scm_error_scm.
377 * error.c (scm_error_scm): new procedure, reimplements scm-error
378 in C and uses scm_error.
380 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
382 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
383 pointer to the Scheme variable read-hash-procedures and intern it
384 in scm_init_read. Modify scm_read_hash_extend and
385 scm_get_hash_procedure to use the pointer.
387 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
389 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
390 (SCM_KEYWORD_STYLE): defined.
392 * read.c (scm_read_opts): add a keywords option. This isn't a
393 boolean option, in case someone wants to add support for DSSSL
395 Setup scm_keyword_prefix symbol.
396 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
398 * I've left keyword support disabled by default, since it doesn't
399 seem to break the module system and it gives R4RS standard behaviour.
400 It can be reactivated with (read-set! keywords 'prefix).
402 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
404 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
405 before constructing arbiter.
407 * eval.c (scm_m_define): Bugfix: Check that the object is a
408 closure before setting the procedure property!
410 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
412 * ports.c: Removed `ungetc-char-ready?'.
414 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
416 * read.c (scm_init_read): intitialise scm_read_hash_procedures
417 (idea from Mikael: make it a pair so scm_permanent object only
419 (scm_read_hash_extend): don't call scm_permanent_object.
420 (ideas from Mikael): if chr is already in the list, replace its
421 procedure instead of appending it again. If proc is #f, remove
423 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
425 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
427 * gdbint.c (gdb_read): update scm_lreadr usage.
429 * load.h: update prototypes.
431 * load.c (scm_primitive_load, scm_read_and_eval_x,
432 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
434 * read.h: add prototype for scm_read_hash_extend. Change args for
437 * read.c (scm_read_hash_procedures): new variable.
438 (scm_read_hash_extend): new procedure.
439 (scm_get_hash_procedure): new procedure.
440 * (scm_lreadr): use scm_get_hash_procedure instead of an argument
441 for extended # processing.
442 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
443 scm_read_token): remove case_i, sharp arguments. Change callers.
445 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
447 * read.h (SCM_N_READ_OPTIONS): increase to 3.
448 (SCM_CASE_INSENSITIVE_P): define.
450 * read.c: add case-insensitive option to scm_read_opts.
451 * (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
452 to determine whether to convert symbol case.
453 (default_case_i): definition removed.
454 * read.c (scm_read_token): if case_i, downcase ic before doing
457 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
459 * configure.in: Added configuration option `guile-debug'.
460 Configure with --enable-guile-debug if you want a bunch of extra
461 functions used for debugging when developing Guile.
463 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
465 * procs.c (make-cclo): New undocumented debugging procedure: Make
466 compiled closure with internal procedure PROC and length LENGTH.
467 Only compiled if GUILE_DEBUG is defined.
469 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
471 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
473 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.

476 with 3 or more args internally to the evaluator.
478 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
480 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
481 with 3 or more args internally to the evaluator. This is mainly
482 because we don't want to pass entry and exit points of the
483 debug support twice, but it also seems to increase the speed of
484 the evaluator for such calls (e. g. (+ 1 2 3)).
486 * * backtrace.c (scm_display_application): New procedure:
487 display-application; Set fancy printing parameters individually
488 for different types of display (backtrace, error, application).
489 (These should of course be customizable!)
491 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
492 clear the CHECK-flags.
494 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
496 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
498 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
500 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
501 from pairs with a GLOC in the car.
503 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
504 otherwise `symbol-hash' will behave badly.
505 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
506 we get segmentation fault!
508 * * symbols.c: Added #include "weaks.h". New functions:
509 `builtin-bindings' and `builtin-weak-bindings'. (These will be
510 moved to an extraneous library when we split libguile.)
512 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
514 * filesys.c (scm_stat): stat now takes fport arguments too as
515 documented in the manual.
517 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
519 * debug.c (scm_single_step): Bugfix: Call continuation with
520 scm_call_continuation instead of throwing to it.
522 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
524 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
525 argument wasn't declared to be optional.
527 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
529 * stime.c (scm_init_stime): Add feature "current-time".
531 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
533 * throw.h: prototype for scm_exit_status.
534 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
535 args to derive an exit status. Allows (quit) to work from a
537 (scm_exit_status): new function.
540 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
542 * eval.c (scm_deval): Removed some old code.
543 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
545 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
548 * symbols.c (msymbolize): Bugfix: Must initialize property list to
551 * procs.c: Introduce the existent C function scm_thunk_p at the
552 Scheme level as well.
554 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
556 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
557 used from C to easily lookup the value of a symbol in the current
560 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
562 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
563 scm_init_unif in this file. This will also fix a previous problem
566 * configure.in: Added AM_MAINTAINER_MODE
568 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
570 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
573 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
575 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
576 source files that are not always included in libguile but should
577 have their dependencies calculated by automake. This variable is
578 recognized by automake, no further magic is needed.
579 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
580 to deal exclusively with *.lo files, as it seems. The *.o files
581 are built automatically when the corresponding *.lo file gets
584 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
586 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
589 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
591 * unif.c (scm_array_set_x): minor change to argument error checking.
593 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
595 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
596 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
597 They should only be included in the library at configure.in's
599 (libguile_la_LDADD): Include the appropriate .lo files here.
600 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
601 so we know when to build them (and their .lo bretheren).
602 * configure.in (LIBLOBJS): New substituted variable. We let
603 configure decide which .o files to include in LIBOBJS, and then
604 put the corresponding list of .lo files in LIBLOBJS. The latter
605 is what we pass to libtool.
606 * Makefile.in, configure: regenerated.
608 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
610 * symbols.c (scm_sysintern0): New function. Contains the core of
611 old scm_sysintern but doesn't take a second value argument.
612 (scm_sysintern): Now uses scm_sysintern0.
613 (scm_sysintern_no_module_lookup): Renamed to
614 scm_sysintern0_no_module_lookup and doesn't take a second value
617 * symbols.h (scm_sysintern0: Added declaration.
619 * options.c (scm_init_opts): Use scm_sysintern0 instead of
620 scm_sysintern when interning option keys. Otherwise we risk
621 destroying the values of already interned variables.
623 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
624 scheme-level boolean (use SCM_NFALSEP).
626 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
628 (scm_backtrace): New function. (C version of old function from
629 boot-9.scm) Motivation: Make it possible to display backtraces
630 without depending on boot-9.scm. (I'm uncertain if this
631 motivation is good enough...)
633 * root.h (scm_root_state): Add member the_last_stack_var.
634 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
636 * root.c (mark_root): Mark scm_the_last_stack_var.
638 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
641 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
643 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
644 1. mark_lazy_catch didn't mark the smob.
645 2. Both functions above have standard variants:
646 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
647 free_lazy_catch --> scm_free0.
649 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
651 * throw.c (scm_internal_lazy_catch): New function.
652 (scm_lazy_catch): Rewritten to use it.
653 (scm_ithrow): Handle the new lazy catch representation.
654 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
655 that doesn't have a jmpbuf is a lazy catch clause.
656 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
657 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
658 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
660 (scm_init_throw): Register the new lazy-catch smob type.
661 * throw.h (scm_internal_lazy_catch): decl for new function.
663 * throw.c (scm_internal_catch): Doc fixes.
665 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
666 configure.in. Including this might cause problems if applications
667 that link against libguile include their own copies of alloca, but
668 if they're using autoconf, they should be adding libguile to LIBS
669 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
670 the copy in libguile, and things will be okay. (I think.)
672 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
674 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
676 strop.h: move prototypes too.
678 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
680 * posix.c (scm_init_posix): don't intern EINTR since it's now done
683 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
684 etc. I deleted them from filesys.c long ago, but didn't
685 notice they were here too (although ineffective since
686 sys/stat.h wasn't included).
688 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
690 * eval.c: Don't define alloca in GCC case. gcc will automatically
691 use __builtin_alloca if appropriate.
693 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
695 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
696 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
697 that values of automatic variables are preserved. See comments
698 for safe_setjmp for details.
700 Change from Thomas Morgan:
701 * variable.c: Include eq.h.
702 (var_equal): New function.
703 (variable_smob): Use var_equal as the discriminator for variables.
705 * throw.c (s_throw): Remove extraneous declaration.
707 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
708 * eval.c: Add necessary CPP cruft to support that.
709 * configure, Makefile.in, scmconfig.h.in: regenerated.
711 Change from Thomas Morgan:
712 * procprop.c (scm_procedure_properties): Convert the Scheme
713 boolean returned by scm_procedure_p into a C boolean before using
714 it as a condition for SCM_ASSERT.
715 (scm_procedure_property): Likewise.
717 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
718 indications of Unixness.
721 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
723 * * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
725 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
727 * read.c (scm_lreadr): use scm_misc_error to improve one of the
728 "unknown # object" error messages.
730 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
731 (scm_i_index) and declare it static. Add a 'direction' argument
732 to indicate what way the search should go.
733 (scm_i_index): throw out-of-range error instead of wrong-type-arg
735 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
736 strop.h: remove scm_i_index, scm_i_rindex prototypes.
738 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
740 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
742 * * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
743 to avoid clash with various scsh forks.
745 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
747 The following two changes (ramap.c, throw.c) are motivated by the
748 apparent unportability of forward declarations of static arrays of
749 the form `static foo bar[];'.
751 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
752 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
754 * throw.c (scm_throw): Moved above scm_ithrow.
756 * options.h: Removed the extern declarations of scm_yes_sym and
757 scm_no_sym since these are static.
759 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
761 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
763 * Makefile.am: remove AWK=@AWK@.
764 Add a rule for generating errnos.list.
765 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
767 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
768 don't extract errnos, just set a variable (avoids the
769 need to recompile error.c just because configure is run.)
771 * unif.h: update prototypes.
772 * unif.c (scm_uniform_array_read,write): change the offset and
773 length arguments to start and end, for consistency.
775 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
777 * ioext.h: update prototypes.
778 * * ioext.c (scm_read_delimited_x): replaces scm_read_line and
779 scm_read_line_x, it's a more general procedure using an
780 interface from scsh. read-line and read-line! are now defined
782 * Note that the new read-line trims the terminator
783 by default, previously it was appended to the returned string. An
784 optional argument specifies how to process the terminator (scsh
785 compatible). For the old behaviour: (read-line port 'concat).
786 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
787 returns a pair, but is converted to multiple values if the scsh
790 socket.h: update prototypes.
791 * socket.c (scm_recvfrom): for consistency with other procedures,
792 take start and end as separate optional arguments.
793 * (scm_recv, scm_recvfrom): don't allow the second argument
794 to be a size, only a buffer. Change the scheme names to
795 recv! and recvfrom!. Don't return the buffer.
797 * ioext.h, posix.h: move prototypes too.
798 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
799 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
800 "read.h" and "unif.h".
801 * ioext.c: include "chars.h"
803 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
805 * dynl.c: The dynamic linking and module registration functions
806 are now defined even when dynamic linking is not available for the
807 host system. Some of their functionality can be done without
808 dynamic linking; when it's really needed, they throw errors.
810 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
812 * configure.in: Only define DYNAMIC_LINKING when one of the system
813 dependent functions is detected.
814 * dynl.c (scm_dynamic_func): New function to get the address of a
815 function in a dynamic object.
816 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
817 produced by scm_dynamic_func as the thing to call.
819 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
821 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
822 (scm_register_module_xxx, scm_registered_modules,
823 scm_clear_registered_modules): New functions.
825 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
827 * symbols.c (scm_sysintern): Renamed to
828 scm_sysintern_no_module_lookup.
829 (scm_sysintern): New function to take the place of the old
830 scm_sysintern. It uses the current toplevel lookup closure to give
831 the symbol its value. This is a temporary hack to put packages
832 like gtcltk into their own module.
833 (scm_can_use_top_level_lookup_closure_var): New variable to tell
834 us whether `scm_top_level_lookup_closure_var' has been initialized
836 * eval.c (scm_init_eval): Set it.
838 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
840 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
841 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
843 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
845 * (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
846 scm_sys_dup): deleted: FD capability will be added to other
848 * Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
849 scm_fd_free, fd_smob, scm_intern_fd.
850 * (scm_open): renamed from scm_sys_open. Return a port instead of
851 an FD object. Make the mode argument optional.
852 * (scm_sys_create): deleted, it's just a special case of open.
853 (scm_init_filesys): move interning of constants O_CREAT etc.,
854 here (were previously using SCM_CONST_LONG macro).
855 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
857 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
858 include "fports.h" and <stdio.h>
859 (scm_stat, scm_select): don't support FD objects.
861 * error.h: adjust scm_syserror_msg prototype.
862 * error.c (scm_syserror_msg): take an extra argument for errno.
863 Using the global value didn't always work, since it could be
864 reset by procedure calls in the message or args arguments.
866 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
867 I don't understand why the check was there (and what about the
870 * strop.c (scm_string_copy): allow shared substrings to be copied.
872 * unif.h: corresponding change to prototypes.
873 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
874 recognize two new optional arguments: offset and length. Allow
875 the port argument to be an integer (file descriptor, for scsh).
876 Include <unistd.h> for "read" prototype.
878 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
880 * socket.c: don't include filesys.h.
882 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
884 * Makefile.am: add AWK=@AWK@ (?)
886 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
888 Add a rule to generate errnos.c from errnos.
889 * error.c (scm_init_error): include errnos.c.
890 * errnos_cnvt.awk: new file, converts the list of errno codes to
892 * errnos_get.c: new file.
893 * errnos.default: new file, contains errnos to try if they can't
894 be extracted from errno.h.
895 * configure.in: if using GCC, try and extract errno codes from
899 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
901 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
902 * Makefile.am: Made libguile into a libtool library.
903 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
904 Set libtool_libs to indicate that libguile is a libtool library.
905 See guile/ChangeLog for details.
906 * .cvsignore: ignore "*.lo", the libtool library objects.
908 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
910 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
911 use htons in getservbyport argument.
913 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
915 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
916 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
919 * objprop.c (scm_object_property): No need to take the CDR of the
920 value returned by scm_object_properties, since Aug 20 change.
922 * configure.in: When checking for struct linger, #include
923 <sys/types.h> as well as <sys/socket.h>. I've never known
924 <sys/types.h> to cause any portability problems, and Solaris's
925 <sys/socket.h> needs it.
926 * configure: Rebuilt.
928 I think the Sun compiler has chosen a perverse way to interpret
929 ANSI declarations combined with K&R definitions. We'll
930 appease it a little bit. But when it invades France, we fight.
931 * print.c (scm_iprlist): Change 'tlr' argument to an int.
932 * print.h (scm_iprlist): Here too.
933 * numbers.c (scm_divbigdig): Change definition to match
934 declaration in numbers.h.
935 * unif.c (scm_makflo): Change definition to match declaration in
938 * init.c (scm_boot_guile): Don't return the value of
939 scm_boot_guile_1. This function doesn't return a value;
940 scm_boot_guile_1 doesn't return a value (or return at all).
942 * eval.c (unmemocopy): Add a semicolon to appease the Sun
945 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
946 compile. I have a feeling this function is a bad idea anyway ---
947 one should always test for features, not systems.
949 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
950 semicolons. Only pure luck kept this from being noticed earlier.
952 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
954 * socket.c (scm_recvfrom): Added missing semicolon.
956 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
958 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
959 the buffer and start and end positions for scsh networking
962 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
964 * configure.in: Revert previous change to this file; the problem
965 is due to transient automake weirdness.
966 * configure: Rebuilt.
968 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
969 PLUGIN/guile.libs. configure generates the latter from the former.
970 * Makefile.in: Rebuilt.
972 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
973 need this if we install scripts, like guile-snarf.
974 * configure: Rebuilt.
976 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
978 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
980 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
982 * socket.c (scm_addr_vector): fix faulty scm_listify.
984 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
986 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
987 style block comment is no longer considered an error.
989 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
991 * PLUGIN/guile.libs.in: New file.
992 * PLUGIN/guile.libs: Removed from repository.
993 * configure.in: Create PLUGIN/guile.libs from
994 PLUGIN/guile.libs.in. This is for including additonal libraries
995 needed for dynamic linking.
996 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
997 instead of PLUGIN/guile.libs.
999 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
1001 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
1003 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
1004 occurrences of the given element from the list, not just the
1005 first. This is how the Emacs Lisp functions behave, how the
1006 analogous Common Lisp functions behave, and (I believe) how the
1007 older Maclisp functions worked. I realize that this change may
1008 break code, but it seemed better to break it before the Guile
1011 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
1012 Their prototypes were already present in gc.h, but they weren't
1014 (scm_init_storage): Initialize scm_protects.
1015 * root.c (scm_protects): New element of scm_sys_protects.
1017 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
1019 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1021 * libguile.h: Added #include "libguile/net_db.h".
1023 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
1024 30 change. That file is only meant for communication between the
1025 configuration process and load.c. If code linked against libguile
1026 wants to get at the paths mentioned in libpath.h, it can call
1027 functions declared in load.h.
1029 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1031 * libguile.h: Removed #include "libguile/fdsocket.h"
1033 * net_db.c: Added #include <sys/socket.h>.
1035 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
1037 * filesys.c (scm_input_waiting_p): use select in preference to
1038 FIONREAD, since the latter doesn't detect EOF.
1039 Throw error if neither select nor FIONREAD available.
1041 * socket.c (scm_connect): take a port, not a fd object.
1042 (scm_fill_sockaddr): throw an error if fam is not recognised.
1043 (scm_bind): use scm_fill_sockaddr.
1044 (scm_listen): take a port, not a fd object.
1045 (scm_accept): take and return a port. return #f in the car if
1046 address can't be got
1047 (scm_sock_fd_to_port): new procedure.
1048 (scm_socket): use scm_sock_fd_to_port.
1049 (scm_addr_vector): throw error if unrecognised address type.
1050 take an extra argument with the calling procedure name.
1051 (scm_getsockname): take a port. return #f if address can't be got.
1052 (scm_getpeername): take a port. return #f if address can't be got.
1053 (scm_recvfrom): take a port. return #f for address component if can't
1055 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
1056 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
1058 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
1060 * throw.c (scm_internal_catch): Make body funcs and handler funcs
1061 use separate data pointers, to allow them to be designed
1062 independently and reused.
1063 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
1064 Renamed from catch_body, catch_handler, and uncaught_throw; made
1066 (struct scm_catch_body_data): Renamed from catch_body_data; moved
1068 (scm_catch): Use the above.
1069 (scm_throw): Don't bother printing a message for an uncaught
1070 throw; we establish a default handler in init.
1071 * throw.h (scm_internal_catch): Prototype updated.
1072 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
1074 (struct scm_body_thunk_data): New structure, used as data
1075 argument to scm_body_thunk.
1076 * init.c (struct main_func_closure): New structure, packaging up
1077 the data to pass to the user's main function.
1078 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
1079 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
1080 scm_internal_catch to establish a catch-all handler, using
1081 scm_handle_by_message. This replaces the special-case code in
1083 (invoke_main_func): Body function for scm_internal_catch; invoke
1084 the user's main function, using the main_func_closure pointer to
1085 decide what to pass it.
1086 * root.c (struct cwdr_body_data): Remove handler_proc member.
1087 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
1088 (cwdr_handler): Removed.
1090 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1092 * socket.h (SCM_P): update bind prototype.
1093 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
1094 include "feature.h".
1095 (scm_socket): return a port, not a file descriptor object.
1096 include "fports.h" and <unistd.h>
1097 (scm_bind): take a port, not a file descriptor object.
1098 take an extra argument for address args.
1100 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
1101 INADDR_NONE, INADDR_LOOPBACK.
1103 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1105 * init.c: include net_db.h and not fdsocket.h.
1106 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
1108 * Makefile.am: corresponding changes.
1109 * socket.h: renamed from fdsocket.h, fix names.
1110 * net_db.h: renamed from socket.h, fix names.
1111 * socket.c: renamed from fdsocket.c.
1112 remove _sys from procedure names.
1113 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
1114 add "socket" to features list.
1115 * net_db.c: renamed from socket.c.
1116 remove _sys from procedure names.
1117 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
1118 add "net-db" to features list.
1119 include "net_db.h". don't include <sys/socket.h> or
1122 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1124 * tags.h (scm_tags): Removed comma at end of last enumerator.
1126 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
1128 Don't use GCC extensions to allocate space for debugging frames.
1129 (Here he goes again! Why do we put up with this?!)
1130 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
1131 an scm_debug_info structure, not an in-line array of them. Add
1132 'info' member, to say how many vect elements we've used, for eval
1134 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
1135 a new variable debug_info_end to mark the end of vect, instead of
1136 the address of the 'info' pointer itself.
1137 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
1138 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
1139 (SCM_APPLY): Explicitly allocate space for debug.vect.
1140 * debug.c (scm_m_start_stack): Same, for vframe.vect.
1141 * stacks.c: Adjusted for new debug frame structure.
1142 (RELOC_INFO, RELOC_FRAME): New macros.
1143 (stack_depth, read_frames): Use them, and new scm_debug_frame
1144 element 'info', instead of magically knowing that eval frames have
1145 an info pointer sitting after vect.
1146 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
1148 (scm_init_stacks): Formatting tweaks.
1150 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
1152 Give GCC more control flow information, so it can be sure that
1153 variables aren't used uninitialized.
1154 * error.h (scm_error, scm_syserror, scm_syserror_msg,
1155 scm_sysmissing, scm_num_overflow, scm_out_of_range,
1156 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
1157 scm_misc_error): Tell GCC that these functions never return.
1158 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
1159 out the field type, call abort if SCM_ASSERT returns, to placate
1161 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
1162 scm_wta ever returns. We can't handle this case anyway, and this
1163 gives the optimizer more information.
1164 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
1165 scm_wta ever returns.
1167 In some cases, the code is fine, but GCC isn't smart enough to
1168 figure that out; this usually happens when one variable is only
1169 initialized and used when a particular condition holds true, and
1170 we know that condition will never change within a given invocation
1171 of the function. In this case, we simply initialize the variables
1172 to placate the compiler, hopefully to a value which will cause a
1173 crash if it is ever actually used.
1174 * print.c (scm_iprin1): Initialize mw_pos.
1175 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
1176 * throw.c (scm_ithrow): Initialize dynpair.
1177 * unif.c (scm_uniform_vector_ref): Initialize cra.
1178 * struct.c (init_struct): Initialize prot.
1179 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
1181 * strports.c (scm_eval_0str): Don't return uninitialized garbage
1182 if EXPR contains no expressions.
1184 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
1186 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
1187 cause an infinite loop (???). So much for the algebraic
1188 equivalency of variable-sized arrays and alloca...
1190 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
1192 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
1193 a SCM boolean, not a C boolean.
1195 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
1197 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
1198 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
1199 rules for raising scm_mtrigger. Previously, unfortunate but not
1200 unlikely circumstances could result in almost constant invokation
1201 of the gc. Now, this situations should be less likely, but they
1202 are not prevented completely.
1204 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
1206 * numbers.c (scm_fuck): Procedure removed; looks like old test
1208 * numbers.h: Prototype removed.
1210 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
1212 * debug.h (scm_debug_frame): Change `vect' member from an in-line
1213 array to a pointer, to match my Nov 21 change in eval.c.
1215 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1217 * libguile.h: Added #include "libguile/backtrace.h", #include
1218 "libguile/stacks.h".
1220 * strings.c (scm_string scm_make_string scm_string_ref
1221 scm_string_set_x scm_string_equal_p scm_string_append):
1222 Bugfix according to scm patch from Aubrey Jaffer:
1223 Corrected long-standing
1224 (not (eqv? (integer->char 128)
1225 (string-ref (make-string 1 (integer->char 128)) 0)))
1226 bug found by John Kozak <jk@noontide.demon.co.uk>.
1228 * strports.c, strports.h: Make scm_eval_0str return the value of
1229 the last expression evaluated (previously, it returned void).
1231 * strports.c, strports.h: New function: scm_read_0str. Does what
1234 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1236 * simpos.c (scm_getenv): return #f if string can't be found in the
1237 environment instead of throwing an exception, for compatibility
1238 with numerous other systems.
1240 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
1242 * Makefile.am (.c.x): Use guile-snarf.
1243 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
1245 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
1247 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1249 * backtrace.c (scm_display_error_message): Made non-static, and
1250 renamed from display_error_message.
1251 * backtrace.h (scm_display_error_message): Added extern decl.
1252 * throw.c (uncaught_throw): Use it to display the error message.
1254 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
1256 * inet_aton.c: Use #if 0, not #ifdef 0.
1258 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
1260 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
1261 to convert the returned value.
1262 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
1263 the offset argument.
1265 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1267 Add new interface to catch/throw, usable from C as well as
1269 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
1270 (scm_internal_catch): New function, replaces...
1271 (scm_catch_apply): Deleted.
1272 * throw.c (scm_catch_apply): Deleted; replaced with a more general
1273 mechanism which is a bit more code, but can be used nicely from C
1274 and implement the Scheme semantics as well.
1275 (scm_internal_catch): This is the replacement; it's named after
1276 the analogous function in Emacs.
1277 (scm_catch): Reimplemented in terms of the above.
1278 (struct catch_body_data, catch_body, catch_handler): New
1279 functions, used by scm_catch.
1280 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
1281 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
1282 support for new cwdr.
1284 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
1287 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
1289 * acconfig.h: Added DYNAMIC_LINKING symbol.
1290 * configure.in: Add option and checks for dynamic linking.
1291 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
1292 dynl.h: New files for dynamic linking support.
1293 * Makefile.am (libguile_a_SOURCES):
1295 (modinclude_HEADERS): Added "dynl.h".
1296 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
1298 * init.c (scm_boot_guile_1): Call
1299 scm_init_dynamic_linking to initialize dynamic linking support.
1301 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
1303 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
1304 (as we Schemers say). It needs to be global, so that I can tweak
1305 it for the proper operation of unexec.
1306 (scm_boot_guile_1_live): New variable, see above.
1308 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
1310 * guile-snarf.sh: Removed.
1311 * PLUGIN/guile.libs: Added dependency for -lm.
1312 * acinclude.m4: Renamed from aclocal.m4.
1313 * PLUGIN/greet: Removed.
1314 * Makefile.am, aclocal.m4: New files.
1315 * configure.in: Updated for Automake.
1317 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
1319 * eval.c (scm_definedp): Use top_level_lookup_closure_var
1320 and not top_level_lookup_thunk_var.
1322 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
1324 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
1326 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
1328 * eval.c (scm_definedp): Incompatibly changed to be a builtin
1329 Scheme function, instead of syntax. Single argument is now a
1332 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1334 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
1335 scm_ra_divide): Properly terminate statements passed as arguments
1336 to IVDEP macros. (Thanks to Bernard Urban.)
1338 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
1339 with non-constant sizes. (Thanks to Bernard Urban.)
1341 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1343 It's an "eval closure", not an "eval thunk." A thunk is a
1344 function of no arguments.
1345 * root.h (struct scm_root_state): Renamed
1346 top_level_lookup_closure_var from top_level_lookup_thunk_var.
1347 (scm_top_level_lookup_closure_var): Renamed from
1348 scm_top_level_lookup_thunk_var.
1349 * root.c (mark_root): Uses changed.
1350 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
1351 * init.c (scm_start_stack): Uses changed.
1352 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
1353 Change scheme-visible name to *top-level-lookup-closure* from
1354 *top-level-lookup-thunk*.
1356 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
1358 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
1359 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
1361 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
1363 * gc.c (struct scm_heap_seg_data): Doc fixes.
1365 * gc.c (scm_gc_sweep): Empty all segments' freelists before
1366 sweeping. Then, prepend each segment's free cells to its
1367 freelist, rather than wiping out the old value. (Thanks to Marius
1370 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
1371 scm_check_freelist, scm_debug_newcell): New functions and
1372 variables, for debugging freelist problems.
1373 * pairs.h (SCM_NEWCELL): New debugging version added.
1374 * gc.h (scm_debug_newcell): Added extern declaration, used by
1375 debugging version of SCM_NEWCELL.
1377 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1379 On some systems <libc.h> conflicts with <unistd.h>, and should not
1380 be #included at all.
1381 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
1382 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
1383 * configure.in: Call it.
1384 * posix.c, filesys.c: Use its results to decide whether or not to
1386 * configure, scmconfig.h.in: Rebuilt with autoconf and
1389 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1391 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
1392 pointer to the stdio stream before calling scm_setbuf0, so the
1393 latter will be able to retrieve it. I'm surprised this didn't
1394 segfault earlier. (Thanks to Christopher Lee.)
1396 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1398 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
1401 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1403 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
1404 number of stack narrowing specifier pairs. The first specifier in
1405 a pair controls inner border, the second the outer border. A
1406 number means cut that number of frames, a procedure object means
1407 cut until that object is found in operator position in a frame.
1409 * root.c (cwdr): Bugfix.
1411 * read.c: Recording of positions disabled by default.
1413 * procs.c (scm_closure_p): New function.
1415 * posix.c (scm_tmpnam): New function.
1417 * load.c: Added #include "throw.h".
1418 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
1421 * load.c, load.h (scm_read_and_eval_x): New function.
1423 * eval.c: Renamed debug option "deval" to "debug".
1425 (scm_eval_x): `eval!' is no longer accessible from the scheme
1426 level. Motivation: We can't allow operations which introduce
1427 glocs into the scheme level. Guile's type system can't handle
1428 these as data. Use `eval' or `read-and-eval!' as replacement.
1430 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
1431 SCM_CONSP since this is a macro!; Set vframe.prev to
1432 scm_last_debug_frame instead of 0. In this way we can look
1433 "above" the virtual start stack frame if we wish.
1434 (scm_debug_hang): New function: Useful for debugging Guile in
1435 certain tricky situations. Will probably be removed later...
1437 * debug.h: Changed semantics of debug option "backtrace". This
1438 option now only indicates whether we want automatic backtrace at
1441 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1443 * ports.c: #include "filesys.h"
1444 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
1446 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
1447 Motivation: This is system specific code which is related to file
1448 I/O. It also may use select. Added code by Gary Houston to
1449 detect presence of character in stdio buffers.
1451 * libguile.h: #include "libguile/libpath.h"
1453 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
1454 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
1455 SCM_SITE_DIR; Install libpath.h among the other include files.
1457 * load.c, load.h (scm_sys_package_data_dir): New function.
1459 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1461 * stacks.h: Bugfix: Don't use tail-array length field as stack
1462 length field! This screwed GC.
1464 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1466 * _scm.h: Added #ifndef around definition of macros min and max.
1468 * __scm.h: Added hooks for threads to plugin to in ints protection
1469 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
1470 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
1471 the main code in these macros duplicated and spread over multiple
1472 files. Renamed SCM_THREADS_SWITCHING_CODE ->
1473 SCM_THREAD_SWITCHING_CODE.
1475 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
1477 * snarf.h: New file.
1478 * guile-snarf.sh: New file.
1479 * Makefile.in (inner_h_files): Added snarf.h
1480 (ancillary, install, uninstall, distclean): Added actions for
1482 (.c.x): Use guile-snarf.
1483 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
1484 (gen_c_files): Note that these depend on guile-snarf.
1485 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
1486 now in "snarf.h". Added #include "snarf.h" to get them.
1487 * libguile.h: Added #include "snarf.h".
1488 (Patches applied and tweaked by Jim Blandy.)
1490 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1492 * socket.c: Use K&R style declaration for 'close'; the GNU coding
1493 standards suggest against providing prototypes for system
1494 functions. Thanks to Greg Troxel.
1496 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1498 * strports.c (scm_eval_0str): New function.
1499 #include "read.h", to get prototype for scm_read.
1500 * Makefile.in (strports.o): Update dependencies.
1501 * strports.h: New prototype.
1503 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
1504 scheme name from "int?" to "integer?". It seems to do the job.
1505 * numbers.h: Rename prototype too.
1506 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
1509 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
1510 scm_num_eq_p): Rename these according to R4RS conventions: call
1511 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
1512 to making libguile R4RS compliant without ice-9...
1514 * load.c (scm_sys_search_load_path): Search for files under all
1515 extensions listed in the %load-extensions variable. If FILENAME
1516 is absolute, return it unchanged, without searching the load path.
1517 (scm_loc_load_extensions): New variable, pointing to
1518 %load-extensions' value cell.
1519 (scm_init_load): Initialize it, and the value it points to.
1520 (scm_primitive_load_path): Improve error reporting.
1522 * load.c (scm_loc_load_hook): New variable, pointing to value cell
1523 of new Scheme variable %load-hook.
1524 (scm_primitive_load): Apply %load-hook to filename.
1526 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
1528 * configure.in: add tests for figuring out whether buffered data
1529 is available in a FILE structure, which is needed by char-ready.
1531 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
1534 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
1535 exceptions using misc_error instead of syserror. It seems a bit
1536 odd to throw an exception if a string can't be found in the
1537 environment, but it's consistent with open-file, stat etc.
1538 (simpos.h): remove sys_ from getenv.
1540 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
1541 occurs, throw an error instead of returning errno. Return value
1543 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1545 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1547 * filesys.c (scm_stat2scm): derive file type and permissions from
1548 the stat mode and append them to the returned vector.
1549 There isn't much overhead in doing this and it avoids the need to
1550 work with S_IRUSR et al. in Scheme.
1551 Define symbols scm_sym_regular etc.
1552 (scm_init_filesys): don't intern S_IRUSR etc.
1554 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1555 and s_primitive_load_path.
1557 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1559 * error.h: don't declare error symbols. prototype for scm_misc_error.
1561 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1564 * error.c: use SCM_SYMBOL to set up error keys.
1565 scm_misc_error: new procedure.
1567 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1569 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1570 between `#!' and `!#' is ignored.
1571 (skip_scsh_block_comment): New function.
1573 * feature.c (scm_set_program_arguments): New argument, FIRST.
1574 * feature.h: Update prototype.
1575 * init.c (scm_boot_guile_1): Pass new argument to
1576 scm_set_program_arguments.
1578 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1580 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1581 (scm_boot_guile): Call scm_set_program_arguments here, later than
1582 the old initialization.
1584 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1585 initialization procedure.
1586 - Delete in, out, err arguments; there are other perfectly good
1587 ways to override these when desired.
1588 - Delete result argument; this function shouldn't ever return.
1589 - Rename init_func argument to main_func, for less confusion.
1590 - Delete boot_cmd argument; main_func is more general.
1591 -Add 'closure' argument, to help people pass data to main_func
1592 without resorting to global variables.
1593 - Abort if reentered; don't bother returning an error code.
1594 - Call scm_init_standard_ports to set up the default/current
1595 standard ports; no need to pass them to scm_start_stack.
1596 - Remove code to evaluate the boot_cmd, and start the repl; let
1597 the user do something like that in main_func if they want.
1598 - Remove code to package up a return value; main_func can do any
1600 - Call exit (0), instead of returning.
1601 (scm_start_stack): Don't initialize the I/O ports here; that's
1602 weird. Delete in, out, err arguments. Move guts to
1603 scm_init_standard_ports, scm_stdio_to_port.
1604 (scm_init_standard_ports): New function, to set up current and
1605 default standard ports.
1606 (scm_start_stack, scm_restart_stack): Make these static.
1607 * init.h (scm_boot_guile): Adjust declaration.
1608 (scm_start_stack, scm_restart_stack): Remove externally
1609 visible declarations for these.
1610 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1612 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1613 written out several times in scm_start_stack.
1614 * fports.h: New declaration for the above.
1616 * feature.c (scm_set_program_arguments): New function.
1617 * feature.h: New declaration for the above.
1619 * ports.c: Formatting tweak.
1621 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1623 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1624 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1625 for obtaining the address of a car or cdr field. Motivation:
1626 &SCM_CXR make assumptions about the internal structure of the
1629 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1630 Motivation: see SCM_CXRLOC.
1632 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1633 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1634 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1635 Motivation: Safer use. Some other macros are defined in terms of
1636 these operations. If these are defined using the SCM_SETCXR
1637 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1638 to inefficiency and an <e1> with side-effects could potentially
1639 break. Also, these particular operations are heavily utilized in
1640 the garbage collector. In unoptimized code there will be a
1643 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1644 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
1645 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
1646 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
1647 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
1648 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1649 vports.c: Cleaned up use of pairs: Don't make any special
1650 assumptions about the internal structure of selectors and
1651 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1652 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1653 (Among other things, this change makes it easier to build Guile
1654 with certain compilers which have problems with casted lvalues.)
1656 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1658 * stacks.c: Improve selection of relevant stack frames when making
1659 a stack object. Introduce one level of indirection in the stack
1660 object to make it possible to "narrow" to a certain region of the
1661 stack. This facilitates making use of more clever algorithms (not
1662 implemented) for selecting relevant frames and gives a cleaner
1663 design since selection of frames can be done independently of
1664 extraction of frames from the real stack.
1665 (scm_stack_id): Also take #t as argument which means look at
1668 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1669 Turn n_tail into an integer directly representing current number
1670 of frames in stack. Add field tail.
1672 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1674 * debug.c (scm_make_memoized): Made it available at scheme level.
1675 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1676 SCM_NIMP before applying heavier predicates in argument checking.
1677 (scm_local_eval): Also take memoized object as argument.
1679 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1680 aren't created with zero length, but should such a strange
1681 creature suddenly turn up...
1683 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1685 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1686 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1688 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1690 * variable.c (scm_make_variable): Make the name hint optional, as
1692 (anonymous_variable_sym): Renamed from variable_sym. All uses
1695 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1696 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1697 of scm_primitive_load_path was also changed to
1698 "primitive-load-path", from "%try-load-path". Callers changed.
1699 We'd like to respect the convention that a function named
1700 "try-mumble" should behave just like the function called "mumble",
1701 but return #f instead of signalling some error.
1702 * load.h: Rename prototypes.
1704 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1706 * print.c (make_print_state, grow_print_state), print.h: Modified
1707 the print state representation: Don't use a tail array for
1708 recording of circular references. Resizing of the print state
1709 structure invalidates the print state pointer. To avoid passing
1710 around an indirect print state reference to all printing
1711 functions, we instead let the print state reference a resizable
1714 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1716 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1717 Don't crash when passed an improper list terminated by a
1718 non-immediate value.
1720 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1722 Allocate data for structures on an eight-byte boundary, as
1723 required by the tagging system.
1724 * struct.c (alloc_struct): New function.
1725 (scm_make_struct, scm_make_vtable_vtable): Call it.
1726 * struct.h (scm_struct_n_extra_words): Bump to 3.
1727 (scm_struct_i_ptr): New "field".
1728 * gc.c (scm_gc_sweep): When we need to free the data, use the
1729 information stored by alloc_struct to find the beginning of the
1730 block allocated to the structure, so we can free it.
1732 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1734 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1737 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1738 (scm_debug_info): New member: id.
1740 * stacks.c: Stacks are now represented as structs; Stacks have an
1741 id given to them by `start-stack'.
1742 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1744 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1745 Changed stack representation.
1747 * debug.c (scm_procedure_name): Try procedure property `name' for
1748 compiled closures aswell.
1750 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
1752 * eval.c: scm_i_name moved to gsubr.c
1753 (scm_m_define): Record names of all kinds of procedure
1754 objects. (Earlier, only closures were recorded.)
1756 * procprop.h: Added declaration of scm_i_name.
1758 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1759 (scm_make_gsubr): Record names of compiled closures.
1761 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1763 * debug.c, debug.h: Removed obsolete code.
1765 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1766 stacks.c: Renamed regs --> scm_contregs.
1768 * print.c (scm_free_print_state): Cleanup print state before
1769 returning it to pool. It is better to do it here than in
1770 scm_prin1 since scm_prin1 is called often.
1772 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1773 s_set_source_property_x): Check that first argument is a pair or a
1776 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1777 scm_i_line, scm_i_column and scm_i_breakpoint global.
1779 * init.c: Added #include "backtrace.h" and #include "stacks.h".
1780 (scm_boot_guile_1): Added calls to scm_init_backtrace and
1783 * debug.h: Added debug object smob declaration and macro
1786 * configure.in: Build with backtrace.o and stacks.o if debug
1789 * Makefile.in: Added entries for new files: backtrace.c,
1790 backtrace.h, stacks.c and stacks.h.
1792 * symbols.c (scm_sym2ovcell): Fixed documentation.
1794 * _scm.h (min, max): Added.
1796 * async.c: Moved `min' macro to _scm.h.
1798 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1799 SCM_BACKTRACE_INDENT.
1801 * eval.c: Added new debug options `maxdepth' and `indent'.
1803 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
1805 * print.h: Added selector SCM_PRINT_STATE.
1807 * print.c: New functions: scm_make_print_state,
1808 scm_free_print_state.
1810 * print.h: Added declarations for scm_make_print_state,
1811 scm_free_print_state.
1813 * debug.c (scm_m_start_stack): New acro.
1815 * debug.h: Small cleanup.
1817 * init.c (scm_boot_guile_1): Moved scm_init_debug below
1820 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

1842 declare functions with prototypes. (Patch thanks to Marius
1845 More prototype-related changes from Marius Vollmer:
1846 * gdb_interface.h: Wrapped header file in #ifdef/#endif
1847 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
1848 * ports.h (ptobfuns): Added prototypes. This means some casting in
1850 * fports.c: Added casts for initializations, since the functions
1851 are defined to take FILE * as their stream argument, not SCM.
1852 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
1853 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
1854 to `char *str_data' to conform to prototype.
1856 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1858 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
1860 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
1862 * stime.c, stime.h: use SCM_P method.
1864 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1866 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
1867 be given at least two arguments. Insist that lst's last element
1868 be a list, but don't make any requirements of its predecessors.
1870 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1872 * eval.c (scm_nconc2last): Revert last change; there seems to be
1873 other stuff going on here.
1875 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1877 * eval.c (scm_nconc2last): Make sure that each element of lst
1878 (which is a list of argument lists, except for the tail) is a
1879 proper list, i.e., finite and terminated by '().
1881 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1883 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
1886 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
1887 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
1890 * vectors.c (scm_make_vector): Fill vectors with the undefined
1891 value, to help make Guile Scheme code more portable to other
1894 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
1895 * symbols.h, tags.h: Doc fixes.
1897 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
1899 * async.c (scm_take_signal): Doc fixes.
1901 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
1903 * numbers.c (scm_divbigint): When the remainder is zero, we don't
1904 want to subtract it from the modulus; we just want to leave it
1907 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
1909 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
1912 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
1914 * throw.c (scm_catch_apply): Finished implementation of
1917 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
1919 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
1921 (scm_init_filesys): set "i/o-extensions" feature.
1924 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
1926 * Makefile.in (root.o): Correct dependencies.
1928 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
1930 * Makefile.in: Added dependency entry for root.o.
1932 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
1933 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
1935 * init.c (scm_start_stack): Set initial root continuation number
1938 * procs.c: New function: scm_thunk_p.
1940 * procs.h: Added declarations of scm_thunk_p.
1942 * root.c: Renamed `call-with-new-root' -->
1943 `call-with-dynamic-root'.
1944 (cwdr): Removed allocation of new root state. This should be done
1945 separately by use of scm_make_root.
1946 (scm_apply_with_dynamic_root): New function: Does what it
1947 sounds like. Needed when spawning threads.
1949 * root.h: Added member last_debug_frame to root state.
1950 Added #include "libguile/debug.h"
1952 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
1953 arguments. The motivation is that code in root.c needs catch
1954 functionality, and we want to avoid code duplication.
1955 New functions: scm_catch, scm_lazy_catch. These are wrappers for
1956 scm_catch_apply. scm_lazy_catch is intended to introduce catch
1957 handlers that run without popping the stack into the dynwind
1960 * throw.h: Added prototypes for scm_catch_apply and
1963 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1965 * root.h (scm_root, scm_set_root): Decouple thread support details
1966 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
1967 SCM_SET_THREAD_LOCAL_DATA.
1969 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
1970 and tortoise scanning loop.
1972 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
1974 * Makefile.in: Rebuild dependencies.
1976 * libguile.h: #include "libguile/print.h" before "smob.h", since
1977 the latter uses the print_state structure.
1979 * throw.c (scm_ithrow): Use the correct variable when checking to
1980 see if a given element of scm_dynwinds is a valid catch.
1982 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
1983 structure, abort; don't just silently ignore the garbage.
1985 * _scm.h: #include "print.h" here, since it seems to be used just
1987 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
1988 strports.c, unif.h: Don't #include "print.h".
1990 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1992 * feature.h (scm_loc_features): Removed external declaration.
1993 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
1995 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1997 * feature.c (scm_init_feature): Added threads feature (needs to be
1998 initialized here, since features doesn't exist when
1999 scm_init_threads is called).
2001 * libguile.h: Added #include "libguile/../threads/threads.h".
2002 (This is a kludge to get thread support working. This should be
2005 * configure.in, acconfig.h: Added flags for thread support.
2007 * scmsigs.c: Define `signal' to be `pthread_signal' if using
2010 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
2011 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
2014 * _scm.h: Added conditional #include "threads.h"
2016 * __scm.h (SCM_ASYNC_TICK): Added call to macro
2017 SCM_THREADS_SWITCHING_CODE.
2019 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
2020 allocate the basic dynamic root object.
2021 (scm_boot_guile): Added call to scm_init_root.
2023 * root.c, root.h: Added root smob.
2024 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
2025 functions: Implements dynamic roots mostly according to spec in
2026 SCM manual. Main difference is that the second argument is a
2027 throw handler rather than an error "thunk".
2029 * root.h: Added declaration of scm_init_root.
2031 * root.c: Added #include "genio.h", #include "smob.h", #include
2032 "pairs.h", #include "throw.h", #include "dynwind.h", #include
2034 (scm_init_root): Added #include "root.x".
2036 * throw.c: Added #include "stackchk.h"
2037 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
2038 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
2039 can be used in scm_call_with_new_root; Added reenabling of stack
2040 checking when catching a throw.
2042 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
2044 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
2046 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
2047 element is not found, as per R4RS.
2049 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2051 * list.c: Doc fixes throughout.
2053 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2055 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
2056 declare the char * to be const. Avoids a warning in rgx.c.
2058 * ports.h: spelling fix.
2060 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
2063 * load.c (scm_sys_try_load_path): throw an error if file not found
2064 (like it says it in NEWS).
2066 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2068 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
2069 PROPS slot to '(), not #f; it's an empty alist.
2071 * throw.h, throw.c: Use SCM_P instead of #if hair.
2073 Remove special support for uncaught throws; see throw.c for
2075 * throw.c (uncaught_throw): New function.
2076 (scm_ithrow): Call uncaught_throw if we don't find a throw
2077 target; don't mess with scm_bad_throw_vcell.
2078 (scm_bad_throw_vcell): Variable deleted.
2079 (scm_init_throw): Don't initialize it.
2081 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
2084 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2086 * numbers.c (scm_istr2int): If the number is short (as most
2087 numbers are), just call scm_small_istr2int to deal with it.
2088 (scm_small_istr2int): New function, created by un-#ifdefing the
2089 non-bignum version of scm_istr2int and renaming it.
2091 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
2093 * load.c (scm_sys_try_load): don't check whether value returned
2094 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
2095 Change the Scheme name from %try-load to primitive-load.
2097 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
2098 Can avoid passing a message, allowing it to be derived in the
2099 error handler (e.g., if we want to throw to the key both from
2102 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
2104 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
2105 references now have a new appearance which is more compact and
2106 also gives a clue about what the target of the reference is.
2107 By setting parameters in the print state, more fancy printing can
2108 be achieved. This is used by the (not yet commited) backtrace
2111 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
2113 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
2116 * print.c: Added #include "struct.h". Removed function
2119 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
2120 scm_iprin1. Removed prototype for scm_prlist.
2122 * arbiters.c (prinarb),
2123 async.c (print_async),
2124 debug.c (prindebugobj, prinmemoized),
2125 eval.c (prinprom, prinmacro),
2126 filesys.c (scm_fd_print, scm_dir_print),
2128 mallocs.c (prinmalloc),
2129 numbers.c, numbers.h (scm_floprint, scm_bigprint),
2130 smob.h (scm_smobfuns),
2131 srcprop.c (prinsrcprops),
2133 unif.c, unif.h (scm_raprin1, rapr1),
2134 variable.c (prin_var): Changed argument `int writing' to
2135 `scm_print_state *pstate'.
2137 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
2138 that it will be called before scm_init_print.
2140 * print.c (scm_prin1): Print states are now allocated when calling
2141 scm_prin1 and then passed around to all printing functions as an
2142 argument. A cache `print_state_pool' enables reuse of print
2144 (scm_make_print_state): New function.
2145 (scm_iprin1): Adaption to print states.
2146 (scm_iprlist): An initial "hare and tortoise" scan brings down
2147 time complexity to O (depth * N). (Better time complexity will be
2148 achieved when the printing code is completely rewritten.)
2150 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2152 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
2153 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
2154 it gets done whether or not the cache variable has a value.
2156 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2158 Distinguish #f and ().
2159 * __scm.h: #undef SICP.
2160 * pairs.h (SCM_EOL): Delete this definition, equating it with
2162 * tags.h (SCM_EOL): Give it a new definition here; I think I found
2163 the value it used to have. Doc fixes, too.
2165 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
2167 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
2168 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
2169 Lord's implementation of structs, allowing for tail arrays as
2170 described in the manual. Also fixed some bugs. (Both the interface
2171 and the implementation should be improved.)
2173 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
2175 * print.c, print.h: Closures now print like #<procedure foo (x)>.
2176 People who whish to see the source can do `(print-enable 'source)'.
2177 Removed #ifdef DEBUG_EXTENSIONS.
2179 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2181 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
2182 integer (assuming for now accepting an integer is a good thing).
2184 * error.c, fports.c: replace use of %S in lgh_error args with %s.
2185 %S will be used instead for write'ing arguments.
2187 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
2188 asserts. fix a few other asserts.
2189 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
2190 scm_uniform_vector_ref, scm_array_set_x,
2191 scm_dimensions_to_unform_array): change args in
2192 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
2193 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
2194 scm_substring_fill_x): likewise.
2195 gsubr.c (scm_gsubr_apply): likewise.
2196 eval.c (SCM_APPLY): likewise.
2198 * eval.c (4 places): replace scm_everr with lgh_error or
2201 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
2202 scm_memory_error): new procedures.
2203 scm_everr: deleted. can use scm_wta, dropping first two args.
2204 scm_error: convert NULL subr to SCM_BOOL_F.
2206 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
2209 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
2212 * error.c, error.h: new error keys: scm_arg_type_key,
2213 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
2215 scm_wta: reimplement using lgh_error instead of scm_everr.
2217 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
2219 * gdbint.c: scm_lread now has one more argument.
2221 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
2222 scm_port_\1; Added mutator scm_set_port_filename_x (used when
2223 loading source from non-file ports, which, e. g., happens when
2224 using the Emacs interface).
2226 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
2229 * read.c: Added code for recording of positions of source code
2230 expressions; New functions: recsexpr, scm_lreadrecparen;
2231 _scm_make_srcprops --> scm_make_srcprops
2232 (scm_flush_ws): Removed updating of positions counters. This work
2233 is already done by scm_gen_getc
2235 * read.h: Added prototype for scm_lreadrecparen
2237 * print.c: Added #include "alist.h"
2239 * eval.c: Added #include "hash.h"
2241 * eq.c: Added #include "ramap.h"

2248 --> scm_make_srcprops
2250 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,

2252 function calls in the definition of the whash access macros.
2254 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
2256 * init.c (scm_boot_guile): Add level of indirection to
2257 scm_boot_guile_1() to ensure that stack base pointer is properly
2258 initialized. There was no guarantee that variable i was the
2259 highest/lowest variable on stack (i.e. the call frame of
2260 scm_boot_guile was not completely protected from gc).
2262 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
2264 * ports.h (scm_port_table): put back file_name, it will be used to
2265 support debugging. Undo related changes in fports.c, ioext.c,
2268 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2270 * ports.h (scm_port_table): remove file_name member for now, it seems
2272 * fports.c (scm_open_file): don't set file_name in PTAB.
2273 (prinfport): don't use file_name in PTAB.
2274 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
2275 * ports.c (scm_add_to_port_table): don't intialize file_name.
2276 (scm_port_file_name): remove for now.
2277 * gc.c (scm_gc_mark): don't mark PTAB file_name.
2279 * fports.h (scm_mkfile): prototype deleted.
2280 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
2282 * debug.c, unif.c: use scm_out_of_range instead of
2283 wta for range errors (ASSERT still needs work).
2285 * error.c, error.h (scm_out_of_range): new procedure.
2287 * error.c, error.h (scm_out_of_range_key): new key.
2289 * posix.c (scm_sync): #else was missing.
2291 * error.c, error.h: append _key to names scm_num_overflow and
2294 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
2295 of consing an empty list.
2296 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
2297 of macros, saves code and string space.
2298 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
2299 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
2300 lower case. Rename scm_syserror_m to scm_syserror_msg.
2301 error.h: prototypes for new procedures.
2303 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
2305 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
2307 * error.c, error.h: setup scm_num_overflow key.
2309 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
2310 Remove definition of SCM_OVSCM_FLOW.
2312 * fports.c (scm_open_file): use SCM_SYSERROR_M.
2314 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
2315 explicit message and args.
2317 * error.c, error.h, __scm.h: change system_error_sym to
2320 * error.c (system_error_sym): remove leading %% from the Scheme name
2323 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
2325 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2327 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
2328 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
2329 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
2330 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
2331 renamed. (These were introduced by unsupervised name
2334 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2336 * print.c: Added code for detection of circular references during
2337 printing. (init_ref_stack, grow_ref_stack): New functions. Added
2338 a hook for printing of closures (accessible via print options).
2339 This leads to a split of calls to scm_iprin1 into two classes:
2340 elementary print operations (e. g. the code which prints a smob)
2341 still use scm_iprin1 while top level calls (like scm_display) use
2342 scm_prin1. scm_prin1 begins by clearing the data structure used
2343 to record reference information.
2345 * print.h: Added declarations of scm_prin1 and scm_prlist.
2347 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
2349 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
2351 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
2353 * error.c (err_head): scm_iprin1 --> scm_prin1
2355 * debug.c: Adjusted header comment.
2359 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>

2363 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2365 * gdbint.c (gdb_read): Now possible to run during GC.
2366 (unmark_port, remark_port): New functions.
2368 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
2370 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
2371 of allocating a new string object. Also, increase size by
2372 the factor 2 instead of 1.5.
2374 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
2376 * __scm.h (SCM_P): Corrected to run under traditional C.
2378 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
2381 * async.c: Calls to scm_sysintern corrected.
2383 * async.h (scm_async_clock): Redundant declaration removed.
2385 * continuations.c (scm_dynthrow): Redundant declaration removed.

2393 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2394 Missing declarations to functions in eval.c added.
2396 * filesys.c: Possibly uninitialized variable rv.
2398 * gc.h (scm_object_addr, scm_unhash_name): Missing
2399 declarations of functions defined in gc.c added.
2401 * genio.c: Possible typos str_data -> wstr_data. ???
2403 * genio.c: Possibly unintended shadowing of local variable
2404 `int c' (gotos out of scope of inner `c'). ???
2406 * init.c: Uninitialized `SCM last' may be used.
2408 * ioext.h: (scm_sys_isatty_p): Typo.
2410 * list.h (scm_list_head): Missing prototype for function in
2413 * numbers.c (scm_two_doubles): Changed from extern to static
2414 (is used only within numbers.c).
2416 * numbers.h: Repeated declarations removed.
2418 * ports.h (scm_close_all_ports_except): Declaration for the
2419 function defined in ports.c added.
2421 * posix.h: Missing declarations added.
2423 * procs.h (scm_make_subr_opt): Missing declaration added.
2425 * socket.h (scm_sys_gethost): Missing declaration added.
2427 * socket.h: Redundant declarations removed (they are in fdsocket.h).
2429 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
2430 Missing declarations added.
2432 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
2434 * struct.c: Uninitialized variable `SCM answer' may be used.
2436 * unif.c (l2ra): Declaration prototype.
2438 * unif.c (scm_array_equal_p): Dummy definition removed (it is
2439 defined in ramap.c).
2441 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
2442 Redundant declarations removed (they are in ramap.h).
2444 * variable.h (scm_make_udvariable,
2445 scm_make_undefined_variable): Declaration corrected to
2446 correspond variable.c.
2448 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
2449 Missing declarations added.
2451 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
2453 * Makefile.in (distclean): Don't forget to delete fd.h.
2455 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2457 * fd.h.in, tags.h: Trivial cleanups.
2459 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
2460 marksweep.h just declared functions from gc.c.
2461 * gc.h, libguile.h: Don't #include "marksweep.h".
2462 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2463 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
2464 dependencies updated.
2466 * libguile.h: Don't #include "files.h"; it's been deleted.
2468 * files.c (scm_sys_delete_file): Moved to filesys.c.
2469 File is now empty; deleted.
2471 * filesys.c: scm_sys_delete_file is now here. Remove
2472 #if's; they seem to rely on remnants of an old portability
2473 regimen. If the problems come up again, solve them properly,
2474 using autoconf. Specifically: Don't test M_SYSV, and #define
2475 remove to be unlink if it's #defined; don't use remove just
2476 because HAVE_STDC_HEADERS is #defined.
2477 * filesys.h: Add declarations for scm_sys_delete_file.
2478 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2479 files.o, files.h, files.c, and files.x.
2480 * init.c: Don't #include "files.h", and don't call scm_init_files.
2482 Use SCM_P instead of PROTO; the latter intrudes on the user's
2484 * params.h: Deleted; definition of SCM_P moved to...
2485 * __scm.h: ... here, where it replaces PROTO macro.
2486 * libguile.h, smob.h: Don't #include "params.h".
2487 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
2488 smob.h: Fix prototypes accordingly.
2489 * Makefile.in: Update dependencies.
2490 (inner_h_files): Remove params.h.
2492 * gc.c: #include "gc.h"; every module should include its header,
2493 to let the compiler cross-check the declarations against the
2496 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2497 simpos.h: #include "libguile/__scm.h".
2499 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2501 * init.c: Don't forget to #include smob.h and init.h.
2502 * Makefile.in: Dependencies updated.
2504 * smob.h: Use PROTO instead of #if __STDC__.
2506 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2508 * __scm.h: Doc fixes.
2510 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2511 <angles>; this allows `make depends' to work properly.
2513 * libguile.h: #include smob.h and pairs.h before the others; they
2514 define typedefs used by other headers.
2516 C files should #include only the header files they need, not
2517 libguile.h (which #includes all the header files); the pointless
2518 recompilation was wasting my time.
2519 * Makefile.in (all .o dependency lists): Regenerated.
2520 * libguile.h: Don't try to get a definition for size_t here...
2521 * __scm.h: Do it here.
2522 * _scm.h: Since this is the internal libguile header, put things
2523 here that all (or a majority) of the libguile files will want.
2524 Don't #include <libguile.h> here; that generates dependencies on
2525 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2526 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2527 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

2624 * weaks.c: Get "weaks.h".
2626 * stackchk.h: #include "libguile/debug.h",
2628 * print.h, read.h: #include "options.h", since everyone who uses
2629 either of these files will need that.
2631 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2632 anyone who uses this file will need them to define the smob
2633 printing functions. Also, get markers.h, since people will need
2634 to #define the mark functions.
2636 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2637 * ports.h: ... to here.
2639 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2640 don't rely on archaic C default type rules.
2642 * fports.h: #include "libguile/ports.h", since you need that in
2643 order to parse this.
2645 * genio.h: #include "libguile/print.h", because you need that to
2646 parse this; don't bother #including "ports.h", since print.h gets
2649 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2651 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2652 this; it's now a reference to an element of *scm_root.
2654 * debug.h: Don't #include "options.h"; the compiler won't be able
2655 to find that once the headers are installed; instead, #include
2656 "libguile/options.h".
2657 * gc.h: Same, with marksweep.h.
2658 * mbstrings.h: Same, with symbols.h.
2659 * scmhob.h: Same, with _scm.h.
2660 * smob.h: Same, with params.h.
2662 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2663 C files; there's no need for this, and it forces recompilations
2666 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2668 * error.c (scm_error): declare scm_error_callback.
2670 * error.h: prototype for scm_error_callback.
2672 * __scm.h: define lgh_error.
2673 (SCM_SYSERROR): redefine using lgh_error.
2675 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2677 * error.c (scm_error): new procedure.
2679 * error.h: prototype for scm_error.
2681 * Makefile.in (install): install scmconfig.h from the current
2682 directory, not $(srcdir).
2684 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2686 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2687 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2688 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
2689 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
2690 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
2691 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,

2693 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2694 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2695 vports.h, weaks.h: #include "libguile/__scm.h", not
2696 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2697 dependencies are within libguile properly.
2699 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2701 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2702 when scmconfig.h doesn't exist.
2704 * load.c (scm_sys_try_load): Correct spelling.
2706 * feature.c (scm_loc_features): Make this static.
2708 * Makefile.in (libpath.h): Omit trailing slash from path. We
2709 shouldn't require it of users, so why put it here?
2711 Move code to initialize and search %load-path from ice-9 to C
2712 code, so we can use the load-path to find the ice-9 boot code;
2713 this makes it easier to run Guile without installing it. See
2714 corresponding changes in guile/Makefile.in.
2715 * feature.c: Move stuff concerned with the load path to load.c.
2716 (scm_compiled_library_path): Deleted.
2717 Don't #include libpath.h here.
2718 * feature.h: Don't mention scm_compiled_library_path.
2719 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2720 <sys/stat.h>, and <unistd.h> (if present).
2721 (R_OK): #define if the system hasn't deigned to.
2722 (scm_loc_load_path): New variable.
2723 (scm_init_load_path, scm_sys_search_load_path,
2724 scm_sys_try_load_path): New functions.
2725 (scm_init_load): Initialize scm_loc_load_path to point to the
2726 value cell of the Scheme %load-path variable.
2727 * load.h: Add declarations for scm_sys_search_load_path,
2728 scm_sys_try_load_path.
2729 * init.c: Call scm_init_load_path.
2730 * Makefile.in (feature.o, load.o): Dependencies updated.
2732 * load.c, load.h: Rewrite using PROTO macro.
2734 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2736 * gc.c (scm_cellp): New function: C predicate to determine if an
2737 SCM value can be regarded as a pointer to a cell on the heap.
2739 * gc.h: Added declaration of scm_cellp.
2741 * gdb_interface.h: New file: The GDB interface header from the GDB
2744 * gdbint.c: New file: GDB interface.
2746 * gdbint.h: New file: GDB interface.
2748 * libguile.h: Added #include <libguile/gdbint.h>.
2750 * init.c (scm_boot_guile): Added scm_init_gdbint.
2752 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2753 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2754 found if object files and source are kept separate).
2756 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2758 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2760 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2762 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2763 TK_SRC_DIR; they're not relevant any more.
2765 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2766 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2768 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2770 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2771 search path, so we can find the <libguile/MUMBLE.h> headers.
2773 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2775 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2776 implicit in the .c.o rule.
2777 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2780 Put the library path in a header file, instead of passing it on
2781 the command line in every compilation.
2782 * Makefile.in (libpath.h): New target.
2783 (feature.o): Depend on libpath.h.
2784 (clean): Delete libpath.h.
2785 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2786 * feature.c: ... #include "libpath.h" here.
2787 * .cvsignore: Ignore libpath.h.
2789 Don't install the unwashed masses of Guile header files in the
2790 main #include path; put most of them in a subdirectory called
2791 'libguile'. This avoids naming conflicts between Guile header
2792 files and system header files (of which there were a few).
2793 * Makefile.in (pkgincludedir): Deleted.
2794 (innerincludedir): New variable; this and $(includedir) are enough.
2795 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
2796 (installed_h_files): Divide this up. Now this variable lists
2797 those header files which should go into $(includedir) (i.e. appear
2798 directly in the #include path), and ...
2799 (inner_h_files): ... this new variable says which files appear in
2800 a subdirectory, and are referred to as <libguile/mumble.h>.
2801 (h_files): List them both.
2802 (install): Create innerincludedir, not pkgincludedir. Put
2803 the installed_h_files and inner_h_files in their proper places.
2804 (uninstall): Corresponding changes.
2805 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2806 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2807 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
2808 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
2809 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
2810 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2811 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2812 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2813 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2814 vports.h, weaks.h: Find __scm.h in its new location.
2815 * __scm.h: Find scmconfig.h and tags.h in their new locations
2816 (they're both "inner" files).
2818 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
2820 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
2822 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2824 * posix.c: Doc fixes.
2826 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
2828 * socket.c: Don't include a prototype for inet_aton; just use a
2829 K&R style declaration, to avoid warnings but minimize the chance
2830 of conflicts with the system.
2832 On NextStep, <utime.h> doesn't define struct utime, unless we
2833 #define _POSIX_SOURCE before #including it.
2834 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
2835 * acconfig.h: New comment text for above CPP symbol.
2836 * configure.in: Call it.
2837 * posix.c: #define _POSIX_SOURCE if it seems necessary.
2839 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
2841 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
2842 testing for __EMX__.
2844 * posix.c: #include <libc.h>, if it exists.
2846 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
2847 don't even know if the latter exists.
2849 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
2850 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
2851 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
2853 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
2855 (scm_init_posix): Use them when initializing the Scheme constants
2858 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2860 * Makefile.in (libdir, includedir, bindir): Use the
2861 autoconf-supplied values, instead of deriving them ourselves.
2862 (pkgincludedir, datadir, pkgdatadir): New variables.
2863 (install, uninstall): Put the header files in a special
2864 subdirectory, not in the main search path.
2866 * Makefile.in (ALL_CFLAGS): Provide the proper value for
2867 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
2869 * Makefile.in (IMPLPATH): Deleted; never used.
2871 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
2872 on the Tcl/Tk source any more.
2873 (INCLUDE_CFLAGS): Remove references to the above.
2875 * Makefile.in (version.o): Corrected dependencies.
2877 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
2879 * libguile.h: #include "version.h"
2881 * init.c (scm_boot_guile): Call scm_init_version.
2882 * gscm.c (gscm_run_scm): Call scm_init_version.
2884 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
2885 GUILE_VERSION): AC_DEFINE these.
2886 (acconfig.h): #undef the above symbols.
2888 * Makefile.in (libobjs): Add version.o.
2889 (installed_h_files): Add version.h.
2890 (c_files): Add version.c.
2891 (gen_c_files): Add version.x.
2892 (version.o): New rule.
2893 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
2894 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
2895 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
2896 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
2897 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
2898 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
2899 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
2900 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
2901 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
2902 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
2903 weaks.o): Add version.h to dependency lists.
2904 (markers.o): Remove duplicate rule.
2906 * version.h: New file.
2908 * version.c: New file.
2910 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2912 * symbols.c (scm_strhash): scm_downcase is now a function, not an
2913 array; use it appropriately. Since GCC is quite happy to
2914 subscript functions, it never warned us about this; we should use
2915 -Wpointer-arith in the future. I guess we never tested
2918 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2920 * socket.c: Doc and copyright fixes.
2922 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2924 * debug.c: Fixed and improved gdb support.
2926 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2928 * socket.c: Added declaration of inet_aton to avoid compiler
2929 warning. (Hope this solution is correct.)
2931 * stime.c: Added declaration of ftime. (This is missing in
2934 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
2936 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2938 * Makefile.in (c_files): add strerror.c.
2940 * strerror.c: new file from Emacs' sysdep.c.
2941 maybe configure should also check for sys_errlist.
2943 * configure.in (AC_REPLACE_FUNCS): add strerror.
2945 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2947 * debug.c (scm_init_debug): Added initialization for
2948 scm_evaluator_traps.
2950 * debug.h, debug.c: Various name changes.
2951 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
2952 "debug-options-interface". See commentary in options.c.
2954 * options.h, options.c: Options now have documentation strings.
2955 Also added a long explanatory commentary.
2957 * eval.c, print.h, print.c, read.h, read.c: Modifications to
2960 * gscm.c, init.c, root.c, throw.c: Bug fixes:
2961 last_debug_info_frame is now updated in all cases.
2963 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
2966 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2968 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
2969 Added option STACK_CHECKING.
2971 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
2973 * Makefile.in: Added {debug,options,srcprop}.{h,c}
2975 * __scm.h: Removed symbols for debugging support.
2977 * acconfig.h: Added symbols for debugging support.
2979 * configure.in: Added user option for debugging support.
2980 --enable-debug will include the debugging code into libguile.a.
2982 * continuations.c (scm_make_cont): Enlarged the #if 0 around
2983 scm_relocate_chunk_to_heap.
2985 * debug.c: New file: low-level debugging support. It also
2986 includes support for debugging with gdb. (The extensions to gdb
2987 are written by Per Bothner at Cygnus.)
2989 * debug.h: New file: low-level debugging support.
2991 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
2992 argument pairs. Extensive modifications to the debugging
2993 evaluator. Added "SECTION:" commentaries to clarify what happens
2994 when, during double compilation. Renamed EVALIMP --> EVALIM.
2995 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
2996 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
2997 the beginning of the file. New procedure: scm_unmemocopy.
2998 Added some global state variables needed by the debugging
2999 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
3000 check_entry, check_apply, check_exit, debug_options and
3001 evaluator_traps. New acro: undefine.
3003 * eval.h: Renamed EVAL --> XEVAL.
3005 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
3006 --> scm_make_weak_key_hash_table.
3008 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
3009 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
3011 * libguile.h: Conditionally include debug.h
3013 * objprop.c (scm_object_properties, scm_set_object_properties_x):
3014 scm_object_properties shouldn't return handle. `handle' now gets
3015 initialized in scm_set_object_properties_x. scm_object_properties
3016 doesn't any longer create an entry in scm_object_whash.
3018 * options.c: New file: handling of run time options.
3020 * options.h: New file: handling of run time options.
3022 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
3024 * print.c: New procedure: scm_print_options
3026 * print.h: Defines for print options.
3028 * read.c: New procedure: scm_read_options
3030 * read.h: Defines for reader options.
3032 * root.h: Added scm_source_whash among scm_sys_protects.
3034 * srcprop.c: New file: source properties.
3036 * srcprop.h: New file: source properties.
3038 * throw.c (jbsmob): Jump buffers are now correctly allocated.
3039 (Bug found by A. Green.)
3041 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3043 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3045 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
3047 * libguile.h: #include "objprop.h"; I guess this was forgotten.
3049 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
3050 and should be called by the final client.
3052 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
3054 * gc.h: Use the PROTO macro when declaring functions.
3055 * gc.c: Use the PROTO macro when declaring static functions.
3056 Remove the CPP hair around function definitions.
3058 * gc.c (scm_init_storage): Initialize scm_asyncs.
3060 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
3061 preprocessor symbol; "__scm.h" is where it might get #defined.
3062 * __scm.h: Similar: #include <scmconfig.h> before testing
3065 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
3067 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
3069 * init.c (scm_boot_guile): Add init_func argument; call
3070 (*init_func) instead of calling scm_appinit; it's ucky to
3071 hard-code names for the user's procedures.
3072 * init.h (scm_boot_guile): Adjust declaration.
3074 * __scm.h (PROTO): New macro, for declaring functions with
3077 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
3078 eliminate all the __STDC__ conditionals.
3079 (scm_boot_guile): Add declaration.
3080 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
3081 Remove __STDC__ conditionals around function definitions; the
3082 declarations in init.h will provide the same information, more
3085 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
3086 complain about it in the error message; the error message is
3087 adequate without that note, and there's nothing the user can do
3090 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
3092 * Makefile.in (ancillary): Drop def.sed.
3094 * posix.c (scm_init_posix): Use numeric values, rather than
3095 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
3096 F_OK. The symbols aren't available on some systems, and I'm
3097 pretty sure their values are fixed by common widespread practice.
3098 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
3100 More functions unavailable on some systems.
3101 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
3102 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
3104 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3105 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
3106 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
3107 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
3108 stub that signals an error as the #else.
3110 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
3112 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
3114 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
3116 * unif.c: include ramap.h.
3118 * read.c (endif): case_insensative_p renamed case_insensitive_p.
3120 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
3122 * ports.c: include sys/ioctl.h.
3124 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
3126 * configure.in: check for sys/ioctl.h.
3128 * ports.c: include <malloc.h> not "malloc.h".
3130 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3132 * fports.c: remove ttyname and tmpnam declarations.
3134 * posix.c: fewer ttyname declarations.
3136 * fports.c: include <string.h> not "string.h".
3138 * init.c, ioext.c: include string.h and unistd.h.
3140 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3142 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
3143 genio.c, simpos.c, vports.c: include string.h.
3145 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
3147 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
3149 (scm_addr_buffer_size): change type from scm_sizet to int.
3150 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
3151 from scm_sizet to int.
3153 * error.c: include unistd.h.
3155 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
3158 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
3160 * __scm.hd, def.sed: deleted.
3162 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
3164 Changes for NeXT, suggested by Robert Brown.
3165 * configure.in: Call AC_TYPE_MODE_T.
3166 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
3167 NeXT. Put header file list in alphabetical order.
3168 * configure, scmconfig.h.in: Regenerated.
3169 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
3171 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
3174 * acconfig.h: New file, providing documentation for the CPP
3175 symbols defined in configure.in
3176 * acconfig-1.5.h: Removed; superceded by the above.
3178 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
3180 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
3182 * fports.c (scm_open_file): don't return #f, throw error.
3184 * ioext.c (fileno): renamed from %fileno.
3185 (soft-fileno): deleted.
3187 * ports.c (scm_port_revealed): don't need to check for -1 from
3189 (scm_set_port_revealed_x): return unspecified, not #f.
3191 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
3193 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
3195 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
3197 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
3199 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3201 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
3202 This is necessary on Ultrix, and doesn't hurt portability.
3204 * Makefile.in (dist-dir): New target, implementing a new dist system.
3205 (installed_h_files): Put in alphabetical order.
3206 Remove duplicate entries for markers.h and unif.h.
3207 (c_files): Remove duplicate entries for markers.c.
3208 (ancillary): Renamed from anillery; all uses changed. Remove
3209 PLUGIN; it's a directory, and needs special treatment in dist-dir.
3210 Remove all the ../doc/* files; doc/Makefile.in handles that.
3212 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
3214 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
3215 every if must have an else, or else the whole command has a
3216 non-zero exit code whenever the if's condition is false.
3218 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
3220 * posix.c: include string.h.
3222 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
3224 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
3227 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
3228 Remove leading % from scheme names.
3229 Do not return error values, call SCM_SYSERROR or similar.
3231 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
3233 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
3235 * struct.c (scm_init_struct): new file.
3237 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
3239 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
3240 (scm_list_head): added list-head for rapidly chopping argument
3241 lists off of longer lists (and similar).
3243 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
3245 * objprop.c (scm_object_property): assq the cdr of the whash
3246 handle for obj, not the handle itself.
3248 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
3250 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
3251 weak hash tables last of all marking to avoid an obscure gc bug.
3252 WARNING: circular lists stored in a weak hash table will hose us.
3254 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
3256 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
3257 new functions similar to scm_substring_move_left_x and
3258 scm_substring_move_right_x.
3260 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
3262 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
3265 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
3267 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
3269 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
3271 * strports.c (scm_strprint_obj): convenience function. C for
3272 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
3274 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
3275 removed to a separate library
3277 * init.c (scm_boot_guile): copied from guile-tcl.c.
3278 Initialization specific to tcl interpreters removed.
3280 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
3282 * ports.c (scm_ports_prehistory): size malloced here doesn't
3283 matter so long as it is non-0 (got rid of "* 4").
3285 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
3287 * gscm.h: gscm_mkarray eliminated (presumably was not being used
3288 since its definition was bogus).
3290 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
3292 * mallocs.[ch]: back again (for rx at least).
3294 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
3296 * ports.c: removed functions relating to the mapping between ports
3297 and descriptors. (That stuff is unix-specific and should be collected
3298 in a separate library).
3300 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
3301 (Tom Mckay@avanticorp.com)
3303 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
3305 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
3306 handled correctly (SCM_FREEP was applied to them) -- test for
3307 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
3308 being overwritten with #f. (brown@grettir.bibliotech.com)
3310 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
3312 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
3313 for a specific symbol or for all symbols.
3315 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
3317 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
3318 keys and weak values confused).
3320 Thu Mar 14 22:20:20 1996 Tom Lord <lord@beehive>
3322 * list.c (scm_last_pair): map '()=>'()
3324 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>
3326 * pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:
3327 Generalized assoc and hash-table functions.
3328 Factored pairs.c into multiple files.
3330 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
3332 * gscm.c (gscm_run_scm): got rid of objprop.
3334 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
3336 * genio.c (scm_getc):
3337 NOTE: fgetc may not be interruptable.
3339 * procprop.c (scm_stand_in_scm_proc):
3340 NOTE: don't use a alist here.
3341 (scm_set_procedure_properties_x): fix type checking throughout this file.
3343 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
3345 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
3346 after freeing part of the port table.
3348 Thu Feb 29 16:21:17 1996 Tom Lord <lord@beehive>
3350 * strports.c (scm_mkstrport):
3351 * vports.c (scm_make_soft_port): allocate a port table entry
3352 (possibly triggering gc) before setting the tag of the corresponding
3355 * pairs.c (scm_delq_x): never throw an error.
3357 * vectors.c (scm_make_vector): made the default vector fill argument
3358 into '() (much more useful than the previous value, "#unspecified")
3360 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
3362 * ports.c (scm_add_to_port_table): Added fields
3363 to port table entries: file_name, line_num, col.
3364 Update these in open_file, gen_getc and gen_ungetc.
3365 Added procedures to access those fields.
3367 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
3369 * procs.c (scm_make_subr_opt): new entry point for making
3372 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
3374 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
3376 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
3378 * numbers.c (scm_exact_p): This function no longer
3379 implements "integer?".
3381 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
3383 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
3384 (scm_gc_stats): return an assoc of useful data. Replaces "room"
3385 and the stats reporting formerlly built into repl.
3387 * repl.[ch]: removed.
3388 GC statistics keeping moved to gc.c.
3389 Other statistics keeping can be done from Scheme.
3390 REPLS are now written in Scheme.

3395 conservatively marked objects).
3397 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
3399 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
3401 * feature.c (scm_compiled_library_path): moved here from repl.c.
3402 This file is for stuff relating specifically to Scheme libraries
3405 * eval.c (scm_m_define): don't give warning about redefinition, don't
3408 NOTE: this should throw a resumable exception with parameters --
3409 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
3411 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
3413 * error.c: scm_warn eliminated.
3415 * read.c (scm_lreadr): extra right paren gets an error, not a warning.

3429 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
3432 * strports.c: don't reveal the port's string to the caller
3433 because it changes size.
3435 (stputc stwrite): check/change the strings length with interrupts
3438 * objprop.c (scm_set_object_property_x &c): use the generic
3439 hashing functions and be threadsafe.
3441 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
3442 (per suggestion jaffer@gnu.ai.mit.edu).

3469 * symbols.c: made the basic symbol table operations atomic.
3471 * root.c &c.: collected stack-specific global state.
3472 linum/colnum etc *should* be port-specific state.

3475 initialization to fix a race condition.
3477 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

3500 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
3501 set the multi_byte flag correctly in symbols. This is wrong.
3502 intern_obbary_soft and msymbolize should take an extra parameter.
3503 Also, weird multibyte symbols don't print correctly.
3504 The weird symbol syntax is also a bit bogus (emacs doesn't quite
3507 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
3509 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
