1 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
3 Changes to work with automake-1.1n, which has better libtool support.
4 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
7 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
9 * Makefile.in: Rebuild.
11 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
13 * stime.c (scm_init_stime): don't define ticks/sec.
14 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
15 return value problem and is still portable.)
17 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
19 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
20 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
21 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
22 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
23 cpp_err_symbols.c): Corresponding changes.
24 * Makefile.in: Regenerated.
26 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
28 * posix.c (scm_putenv): don't check HAVE_PUTENV.
29 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
30 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
31 * putenv.c: new file, from sh-utils 1.12.
33 * posix.c (scm_environ): use malloc in place of scm_must_malloc
34 since allocation isn't for Scheme objects.
35 (scm_putenv): copy strings before placing in the environment.
37 * stime.c (scm_current_time): throw an error if time returns -1,
38 instead of returning #f.
39 (scm_get_internal_real_time, scm_get_internal_real_time): use
40 scm_long2num for return value instead of SCM_MAKINUM.
42 * stime.h: prototypes updated.
44 * stime.c (scm_time_in_msec): apparently unused, deleted.
46 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
48 * configure.in: check for gettimeofday.
50 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
51 which may be more usefully portable than a gettimeofday interface.
53 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
55 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
57 * Makefile.in: Regenerated.
59 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
61 * stime.c (filltime): recovered static procedure.
62 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
65 * posix.h: add prototype for scm_close_pipe, remove prototypes for
66 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
68 * * posix.c (scm_mknod): split the mode argument into type and perms
69 arguments, like the extra fields returned by stat.
71 * fports.c (scm_pipob): set the close, free and print procedures.
72 (scm_close_pipe): new procedure.
74 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
75 define them in boot-9.scm
77 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
79 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
80 wan't defined. Don't include fd.h.
82 * Previously fd.h was regenerated whenever configure was run,
83 forcing a couple of files to be recompiled.
85 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
86 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
87 Check for _fileno as well as _file.
89 * ioext.c: don't fd.h.
90 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
93 * Change the stratigy for getting information about errno
94 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
95 generating lists of symbols during the build process, which will
96 not always work, include comprehensive lists in the distribution.
97 To help keep the lists up to date, the "check_signals" and
98 "check_errnos" make targets can be used.
100 * configure.in: don't check for a command to extract errno codes.
101 * Makefile.am: update file lists, remove errnos.list and errnos.c
102 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
103 check_errnos targets.
104 (CLEANFILES): remove errnos.c and errnos.list, add
105 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
106 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
107 * errnos.default: deleted.
108 * cpp_signal.c: new file.
109 * cpp_errno.c: renamed from errnos_get.c.
110 * cpp_err_symbols, cpp_sig_symbols: new files.
111 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
112 * error.c (scm_init_error): #include cpp_err_symbols instead of
114 * posix.c (scm_init_posix): don't intern signal symbols. #include
117 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
119 * strop.c (scm_i_index): allow the lower bound to be equal to the
120 length of the string, so a null string doesn't always give an error.
122 * posix.h: new prototypes.
123 * posix.c (scm_status_exit_val, scm_status_term_sig,
124 scm_status_stop_sig): new functions, as in scsh. They break down
125 process status values as returned by waitpid.
127 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
129 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
130 configure doesn't know about it.
132 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
134 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
136 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
137 which defines C variables with global linkage.
139 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
141 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
144 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
146 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
147 has time to check why this doesn't work well with continuations.
149 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
151 * Fix shell syntax error; some shells won't tolerate
152 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
154 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
156 * posix.c (scm_uname): throw an error if uname fails instead
159 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
161 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
164 * async.c (scm_ints_disabled): definition moved from error.c.
166 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
168 * acconfig.h: Removed PACKAGE.
170 * scmconfig.h.in: Regenerated.
172 * snarf.h: g++ says it's non-portable not to specify the first
173 argument in a varargs declaration. I introduced the first
174 argument by using preprocessor conditionals.
176 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
178 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
179 (scm_freopen): use RO string macros for filename and modes.
180 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
182 * posix.c (scm_getgrgid): simplify conversion of name to C string.
183 (scm_mknod): use RO string macros for path.
185 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
186 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
188 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
189 use SCM_ROSTRINGP and SCM_ROCHARS.
191 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
193 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
196 * ramap.c (scm_ra_matchp, scm_ra_matchp, scm_array_fill_int, racp,
197 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
198 support for byte vectors.
200 * print.c (scm_iprin1): Limit number of vector elements printed
201 according to pstate->length.
203 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
205 * backtrace.c (scm_display_error_message): don't segv if message
208 * error.h: prototype for scm_error_scm.
210 * error.c (scm_error_scm): new procedure, reimplements scm-error
211 in C and uses scm_error.
213 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
215 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
216 pointer to the Scheme variable read-hash-procedures and intern it
217 in scm_init_read. Modify scm_read_hash_extend and
218 scm_get_hash_procedure to use the pointer.
220 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
222 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
223 (SCM_KEYWORD_STYLE): defined.
225 * read.c (scm_read_opts): add a keywords option. This isn't a
226 boolean option, in case someone wants to add support for DSSSL
228 Setup scm_keyword_prefix symbol.
229 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
231 * I've left keyword support disabled by default, since it doesn't
232 seem to break the module system and it gives R4RS standard behaviour.
233 It can be reactivated with (read-set! keywords 'prefix).
235 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
237 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
238 before constructing arbiter.
240 * eval.c (scm_m_define): Bugfix: Check that the object is a
241 closure before setting the procedure property!
243 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
245 * ports.c: Removed `ungetc-char-ready?'.
247 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
249 * read.c (scm_init_read): intitialise scm_read_hash_procedures
250 (idea from Mikael: make it a pair so scm_permanent object only
252 (scm_read_hash_extend): don't call scm_permanent_object.
253 (ideas from Mikael): if chr is already in the list, replace its
254 procedure instead of appending it again. If proc is #f, remove
256 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
258 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
260 * gdbint.c (gdb_read): update scm_lreadr usage.
262 * load.h: update prototypes.
264 * load.c (scm_primitive_load, scm_read_and_eval_x,
265 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
267 * read.h: add prototype for scm_read_hash_extend. Change args for
270 * read.c (scm_read_hash_procedures): new variable.
271 (scm_read_hash_extend): new procedure.
272 (scm_get_hash_procedure): new procedure.
273 * (scm_lreadr): use scm_get_hash_procedure instead of an argument
274 for extended # processing.
275 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
276 scm_read_token): remove case_i, sharp arguments. Change callers.
278 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
280 * read.h (SCM_N_READ_OPTIONS): increase to 3.
281 (SCM_CASE_INSENSITIVE_P): define.
283 * read.c: add case-insensitive option to scm_read_opts.
284 * (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
285 to determine whether to convert symbol case.
286 (default_case_i): definition removed.
287 * read.c (scm_read_token): if case_i, downcase ic before doing
290 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
292 * configure.in: Added configuration option `guile-debug'.
293 Configure with --enable-guile-debug if you want a bunch of extra
294 functions used for debugging when developing Guile.
296 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
298 * procs.c (make-cclo): New undocumented debugging procedure: Make
299 compiled closure with internal procedure PROC and length LENGTH.
300 Only compiled if GUILE_DEBUG is defined.
302 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
304 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
306 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
308 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
309 with 3 or more args internally to the evaluator.
311 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
313 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
314 with 3 or more args internally to the evaluator. This is mainly
315 because we don't want to pass entry and exit points of the
316 debug support twice, but it also seems to increase the speed of
317 the evaluator for such calls (e. g. (+ 1 2 3)).
319 * * backtrace.c (scm_display_application): New procedure:
320 display-application; Set fancy printing parameters individually
321 for different types of display (backtrace, error, application).
322 (These should of course be customizable!)
324 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
325 clear the CHECK-flags.
327 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
329 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
331 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
333 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
334 from pairs with a GLOC in the car.
336 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
337 otherwise `symbol-hash' will behave badly.
338 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
339 we get segmentation fault!
341 * * symbols.c: Added #include "weaks.h". New functions:
342 `builtin-bindings' and `builtin-weak-bindings'. (These will be
343 moved to an extraneous library when we split libguile.)
345 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
347 * filesys.c (scm_stat): stat now takes fport arguments too as
348 documented in the manual.
350 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
352 * debug.c (scm_single_step): Bugfix: Call continuation with
353 scm_call_continuation instead of throwing to it.
355 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
357 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
358 argument wasn't declared to be optional.
360 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
362 * stime.c (scm_init_stime): Add feature "current-time".
364 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
366 * throw.h: prototype for scm_exit_status.
367 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
368 args to derive an exit status. Allows (quit) to work from a
370 (scm_exit_status): new function.
373 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
375 * eval.c (scm_deval): Removed some old code.
376 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
378 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
381 * symbols.c (msymbolize): Bugfix: Must initialize property list to
384 * procs.c: Introduce the existent C function scm_thunk_p at the
385 Scheme level as well.
387 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
389 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
390 used from C to easily lookup the value of a symbol in the current
393 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
395 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
396 scm_init_unif in this file. This will also fix a previous problem
399 * configure.in: Added AM_MAINTAINER_MODE
401 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
403 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
406 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
408 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
409 source files that are not always included in libguile but should
410 have their dependencies calculated by automake. This variable is
411 recognized by automake, no further magic is needed.
412 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
413 to deal exclusively with *.lo files, as it seems. The *.o files
414 are built automatically when the corresponding *.lo file gets
417 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
419 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
422 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
424 * unif.c (scm_array_set_x): minor change to argument error checking.
426 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
428 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
429 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
430 They should only be included in the library at configure.in's
432 (libguile_la_LDADD): Include the appropriate .lo files here.
433 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
434 so we know when to build them (and their .lo bretheren).
435 * configure.in (LIBLOBJS): New substituted variable. We let
436 configure decide which .o files to include in LIBOBJS, and then
437 put the corresponding list of .lo files in LIBLOBJS. The latter
438 is what we pass to libtool.
439 * Makefile.in, configure: regenerated.
441 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
443 * symbols.c (scm_sysintern0): New function. Contains the core of
444 old scm_sysintern but doesn't take a second value argument.
445 (scm_sysintern): Now uses scm_sysintern0.
446 (scm_sysintern_no_module_lookup): Renamed to
447 scm_sysintern0_no_module_lookup and doesn't take a second value
450 * symbols.h (scm_sysintern0: Added declaration.
452 * options.c (scm_init_opts): Use scm_sysintern0 instead of
453 scm_sysintern when interning option keys. Otherwise we risk
454 destroying the values of already interned variables.
456 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
457 scheme-level boolean (use SCM_NFALSEP).
459 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
461 (scm_backtrace): New function. (C version of old function from
462 boot-9.scm) Motivation: Make it possible to display backtraces
463 without depending on boot-9.scm. (I'm uncertain if this
464 motivation is good enough...)
466 * root.h (scm_root_state): Add member the_last_stack_var.
467 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
469 * root.c (mark_root): Mark scm_the_last_stack_var.
471 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
474 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
476 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
477 1. mark_lazy_catch didn't mark the smob.
478 2. Both functions above have standard variants:
479 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
480 free_lazy_catch --> scm_free0.
482 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
484 * throw.c (scm_internal_lazy_catch): New function.
485 (scm_lazy_catch): Rewritten to use it.
486 (scm_ithrow): Handle the new lazy catch representation.
487 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
488 that doesn't have a jmpbuf is a lazy catch clause.
489 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
490 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
491 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
493 (scm_init_throw): Register the new lazy-catch smob type.
494 * throw.h (scm_internal_lazy_catch): decl for new function.
496 * throw.c (scm_internal_catch): Doc fixes.
498 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
499 configure.in. Including this might cause problems if applications
500 that link against libguile include their own copies of alloca, but
501 if they're using autoconf, they should be adding libguile to LIBS
502 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
503 the copy in libguile, and things will be okay. (I think.)
505 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
507 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
509 strop.h: move prototypes too.
511 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
513 * posix.c (scm_init_posix): don't intern EINTR since it's now done
516 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
517 etc. I deleted them from filesys.c long ago, but didn't
518 notice they were here too (although ineffective since
519 sys/stat.h wasn't included).
521 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
523 * eval.c: Don't define alloca in GCC case. gcc will automatically
524 use __builtin_alloca if appropriate.
526 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
528 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
529 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
530 that values of automatic variables are preserved. See comments
531 for safe_setjmp for details.
533 Change from Thomas Morgan:
534 * variable.c: Include eq.h.
535 (var_equal): New function.
536 (variable_smob): Use var_equal as the discriminator for variables.
538 * throw.c (s_throw): Remove extraneous declaration.
540 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
541 * eval.c: Add necessary CPP cruft to support that.
542 * configure, Makefile.in, scmconfig.h.in: regenerated.
544 Change from Thomas Morgan:
545 * procprop.c (scm_procedure_properties): Convert the Scheme
546 boolean returned by scm_procedure_p into a C boolean before using
547 it as a condition for SCM_ASSERT.
548 (scm_procedure_property): Likewise.
550 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
551 indications of Unixness.
554 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
556 * * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
558 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
560 * read.c (scm_lreadr): use scm_misc_error to improve one of the
561 "unknown # object" error messages.
563 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
564 (scm_i_index) and declare it static. Add a 'direction' argument
565 to indicate what way the search should go.
566 (scm_i_index): throw out-of-range error instead of wrong-type-arg
568 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
569 strop.h: remove scm_i_index, scm_i_rindex prototypes.
571 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
573 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
575 * * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
576 to avoid clash with various scsh forks.
578 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
580 The following two changes (ramap.c, throw.c) are motivated by the
581 apparent unportability of forward declarations of static arrays of
582 the form `static foo bar[];'.
584 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
585 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
587 * throw.c (scm_throw): Moved above scm_ithrow.
589 * options.h: Removed the extern declarations of scm_yes_sym and
590 scm_no_sym since these are static.
592 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
594 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
596 * Makefile.am: remove AWK=@AWK@.
597 Add a rule for generating errnos.list.
598 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
600 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
601 don't extract errnos, just set a variable (avoids the
602 need to recompile error.c just because configure is run.)
604 * unif.h: update prototypes.
605 * unif.c (scm_uniform_array_read,write): change the offset and
606 length arguments to start and end, for consistency.
608 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
610 * ioext.h: update prototypes.
611 * * ioext.c (scm_read_delimited_x): replaces scm_read_line and
612 scm_read_line_x, it's a more general procedure using an
613 interface from scsh. read-line and read-line! are now defined
615 * Note that the new read-line trims the terminator
616 by default, previously it was appended to the returned string. An
617 optional argument specifies how to process the terminator (scsh
618 compatible). For the old behaviour: (read-line port 'concat).
619 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
620 returns a pair, but is converted to multiple values if the scsh
623 socket.h: update prototypes.
624 * socket.c (scm_recvfrom): for consistency with other procedures,
625 take start and end as separate optional arguments.
626 * (scm_recv, scm_recvfrom): don't allow the second argument
627 to be a size, only a buffer. Change the scheme names to
628 recv! and recvfrom!. Don't return the buffer.
630 * ioext.h, posix.h: move prototypes too.
631 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
632 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
633 "read.h" and "unif.h".
634 * ioext.c: include "chars.h"
636 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
638 * dynl.c: The dynamic linking and module registration functions
639 are now defined even when dynamic linking is not available for the
640 host system. Some of their functionality can be done without
641 dynamic linking; when it's really needed, they throw errors.
643 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
645 * configure.in: Only define DYNAMIC_LINKING when one of the system
646 dependent functions is detected.
647 * dynl.c (scm_dynamic_func): New function to get the address of a
648 function in a dynamic object.
649 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
650 produced by scm_dynamic_func as the thing to call.
652 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
654 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
655 (scm_register_module_xxx, scm_registered_modules,
656 scm_clear_registered_modules): New functions.
658 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
660 * symbols.c (scm_sysintern): Renamed to
661 scm_sysintern_no_module_lookup.
662 (scm_sysintern): New function to take the place of the old
663 scm_sysintern. It uses the current toplevel lookup closure to give
664 the symbol its value. This is a temporary hack to put packages
665 like gtcltk into their own module.
666 (scm_can_use_top_level_lookup_closure_var): New variable to tell
667 us whether `scm_top_level_lookup_closure_var' has been initialized
669 * eval.c (scm_init_eval): Set it.
671 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
673 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
674 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
676 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
678 * (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
679 scm_sys_dup): deleted: FD capability will be added to other
681 * Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
682 scm_fd_free, fd_smob, scm_intern_fd.
683 * (scm_open): renamed from scm_sys_open. Return a port instead of
684 an FD object. Make the mode argument optional.
685 * (scm_sys_create): deleted, it's just a special case of open.
686 (scm_init_filesys): move interning of constants O_CREAT etc.,
687 here (were previously using SCM_CONST_LONG macro).
688 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
690 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
691 include "fports.h" and <stdio.h>
692 (scm_stat, scm_select): don't support FD objects.
694 * error.h: adjust scm_syserror_msg prototype.
695 * error.c (scm_syserror_msg): take an extra argument for errno.
696 Using the global value didn't always work, since it could be
697 reset by procedure calls in the message or args arguments.
699 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
700 I don't understand why the check was there (and what about the
703 * strop.c (scm_string_copy): allow shared substrings to be copied.
705 * unif.h: corresponding change to prototypes.
706 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
707 recognize two new optional arguments: offset and length. Allow
708 the port argument to be an integer (file descriptor, for scsh).
709 Include <unistd.h> for "read" prototype.
711 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
713 * socket.c: don't include filesys.h.
715 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
717 * Makefile.am: add AWK=@AWK@ (?)
719 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
721 Add a rule to generate errnos.c from errnos.
722 * error.c (scm_init_error): include errnos.c.
723 * errnos_cnvt.awk: new file, converts the list of errno codes to
725 * errnos_get.c: new file.
726 * errnos.default: new file, contains errnos to try if they can't
727 be extracted from errno.h.
728 * configure.in: if using GCC, try and extract errno codes from
732 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
734 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
735 * Makefile.am: Made libguile into a libtool library.
736 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
737 Set libtool_libs to indicate that libguile is a libtool library.
738 See guile/ChangeLog for details.
739 * .cvsignore: ignore "*.lo", the libtool library objects.
741 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
743 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
744 use htons in getservbyport argument.
746 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
748 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
749 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
752 * objprop.c (scm_object_property): No need to take the CDR of the
753 value returned by scm_object_properties, since Aug 20 change.
755 * configure.in: When checking for struct linger, #include
756 <sys/types.h> as well as <sys/socket.h>. I've never known
757 <sys/types.h> to cause any portability problems, and Solaris's
758 <sys/socket.h> needs it.
759 * configure: Rebuilt.
761 I think the Sun compiler has chosen a perverse way to interpret
762 ANSI declarations combined with K&R definitions. We'll
763 appease it a little bit. But when it invades France, we fight.
764 * print.c (scm_iprlist): Change 'tlr' argument to an int.
765 * print.h (scm_iprlist): Here too.
766 * numbers.c (scm_divbigdig): Change definition to match
767 declaration in numbers.h.
768 * unif.c (scm_makflo): Change definition to match declaration in
771 * init.c (scm_boot_guile): Don't return the value of
772 scm_boot_guile_1. This function doesn't return a value;
773 scm_boot_guile_1 doesn't return a value (or return at all).
775 * eval.c (unmemocopy): Add a semicolon to appease the Sun
778 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
779 compile. I have a feeling this function is a bad idea anyway ---
780 one should always test for features, not systems.
782 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
783 semicolons. Only pure luck kept this from being noticed earlier.
785 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
787 * socket.c (scm_recvfrom): Added missing semicolon.
789 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
791 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
792 the buffer and start and end positions for scsh networking
795 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
797 * configure.in: Revert previous change to this file; the problem
798 is due to transient automake weirdness.
799 * configure: Rebuilt.
801 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
802 PLUGIN/guile.libs. configure generates the latter from the former.
803 * Makefile.in: Rebuilt.
805 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
806 need this if we install scripts, like guile-snarf.
807 * configure: Rebuilt.
809 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
811 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
813 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
815 * socket.c (scm_addr_vector): fix faulty scm_listify.
817 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
819 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
820 style block comment is no longer considered an error.
822 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
824 * PLUGIN/guile.libs.in: New file.
825 * PLUGIN/guile.libs: Removed from repository.
826 * configure.in: Create PLUGIN/guile.libs from
827 PLUGIN/guile.libs.in. This is for including additonal libraries
828 needed for dynamic linking.
829 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
830 instead of PLUGIN/guile.libs.
832 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
834 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
836 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
837 occurrences of the given element from the list, not just the
838 first. This is how the Emacs Lisp functions behave, how the
839 analogous Common Lisp functions behave, and (I believe) how the
840 older Maclisp functions worked. I realize that this change may
841 break code, but it seemed better to break it before the Guile
844 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
845 Their prototypes were already present in gc.h, but they weren't
847 (scm_init_storage): Initialize scm_protects.
848 * root.c (scm_protects): New element of scm_sys_protects.
850 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
852 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
854 * libguile.h: Added #include "libguile/net_db.h".
856 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
857 30 change. That file is only meant for communication between the
858 configuration process and load.c. If code linked against libguile
859 wants to get at the paths mentioned in libpath.h, it can call
860 functions declared in load.h.
862 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
864 * libguile.h: Removed #include "libguile/fdsocket.h"
866 * net_db.c: Added #include <sys/socket.h>.
868 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
870 * filesys.c (scm_input_waiting_p): use select in preference to
871 FIONREAD, since the latter doesn't detect EOF.
872 Throw error if neither select nor FIONREAD available.
874 * socket.c (scm_connect): take a port, not a fd object.
875 (scm_fill_sockaddr): throw an error if fam is not recognised.
876 (scm_bind): use scm_fill_sockaddr.
877 (scm_listen): take a port, not a fd object.
878 (scm_accept): take and return a port. return #f in the car if
880 (scm_sock_fd_to_port): new procedure.
881 (scm_socket): use scm_sock_fd_to_port.
882 (scm_addr_vector): throw error if unrecognised address type.
883 take an extra argument with the calling procedure name.
884 (scm_getsockname): take a port. return #f if address can't be got.
885 (scm_getpeername): take a port. return #f if address can't be got.
886 (scm_recvfrom): take a port. return #f for address component if can't
888 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
889 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
891 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
893 * throw.c (scm_internal_catch): Make body funcs and handler funcs
894 use separate data pointers, to allow them to be designed
895 independently and reused.
896 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
897 Renamed from catch_body, catch_handler, and uncaught_throw; made
899 (struct scm_catch_body_data): Renamed from catch_body_data; moved
901 (scm_catch): Use the above.
902 (scm_throw): Don't bother printing a message for an uncaught
903 throw; we establish a default handler in init.
904 * throw.h (scm_internal_catch): Prototype updated.
905 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
907 (struct scm_body_thunk_data): New structure, used as data
908 argument to scm_body_thunk.
909 * init.c (struct main_func_closure): New structure, packaging up
910 the data to pass to the user's main function.
911 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
912 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
913 scm_internal_catch to establish a catch-all handler, using
914 scm_handle_by_message. This replaces the special-case code in
916 (invoke_main_func): Body function for scm_internal_catch; invoke
917 the user's main function, using the main_func_closure pointer to
918 decide what to pass it.
919 * root.c (struct cwdr_body_data): Remove handler_proc member.
920 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
921 (cwdr_handler): Removed.
923 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
925 * socket.h (SCM_P): update bind prototype.
926 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
928 (scm_socket): return a port, not a file descriptor object.
929 include "fports.h" and <unistd.h>
930 (scm_bind): take a port, not a file descriptor object.
931 take an extra argument for address args.
933 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
934 INADDR_NONE, INADDR_LOOPBACK.
936 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
938 * init.c: include net_db.h and not fdsocket.h.
939 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
941 * Makefile.am: corresponding changes.
942 * socket.h: renamed from fdsocket.h, fix names.
943 * net_db.h: renamed from socket.h, fix names.
944 * socket.c: renamed from fdsocket.c.
945 remove _sys from procedure names.
946 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
947 add "socket" to features list.
948 * net_db.c: renamed from socket.c.
949 remove _sys from procedure names.
950 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
951 add "net-db" to features list.
952 include "net_db.h". don't include <sys/socket.h> or
955 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
957 * tags.h (scm_tags): Removed comma at end of last enumerator.
959 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
961 Don't use GCC extensions to allocate space for debugging frames.
962 (Here he goes again! Why do we put up with this?!)
963 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
964 an scm_debug_info structure, not an in-line array of them. Add
965 'info' member, to say how many vect elements we've used, for eval
967 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
968 a new variable debug_info_end to mark the end of vect, instead of
969 the address of the 'info' pointer itself.
970 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
971 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
972 (SCM_APPLY): Explicitly allocate space for debug.vect.
973 * debug.c (scm_m_start_stack): Same, for vframe.vect.
974 * stacks.c: Adjusted for new debug frame structure.
975 (RELOC_INFO, RELOC_FRAME): New macros.
976 (stack_depth, read_frames): Use them, and new scm_debug_frame
977 element 'info', instead of magically knowing that eval frames have
978 an info pointer sitting after vect.
979 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
981 (scm_init_stacks): Formatting tweaks.
983 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
985 Give GCC more control flow information, so it can be sure that
986 variables aren't used uninitialized.
987 * error.h (scm_error, scm_syserror, scm_syserror_msg,
988 scm_sysmissing, scm_num_overflow, scm_out_of_range,
989 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
990 scm_misc_error): Tell GCC that these functions never return.
991 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
992 out the field type, call abort if SCM_ASSERT returns, to placate
994 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
995 scm_wta ever returns. We can't handle this case anyway, and this
996 gives the optimizer more information.
997 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
998 scm_wta ever returns.
1000 In some cases, the code is fine, but GCC isn't smart enough to
1001 figure that out; this usually happens when one variable is only
1002 initialized and used when a particular condition holds true, and
1003 we know that condition will never change within a given invocation
1004 of the function. In this case, we simply initialize the variables
1005 to placate the compiler, hopefully to a value which will cause a
1006 crash if it is ever actually used.
1007 * print.c (scm_iprin1): Initialize mw_pos.
1008 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
1009 * throw.c (scm_ithrow): Initialize dynpair.
1010 * unif.c (scm_uniform_vector_ref): Initialize cra.
1011 * struct.c (init_struct): Initialize prot.
1012 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
1014 * strports.c (scm_eval_0str): Don't return uninitialized garbage
1015 if EXPR contains no expressions.
1017 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
1019 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
1020 cause an infinite loop (???). So much for the algebraic
1021 equivalency of variable-sized arrays and alloca...
1023 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
1025 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
1026 a SCM boolean, not a C boolean.
1028 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
1030 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
1031 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
1032 rules for raising scm_mtrigger. Previously, unfortunate but not
1033 unlikely circumstances could result in almost constant invokation
1034 of the gc. Now, this situations should be less likely, but they
1035 are not prevented completely.
1037 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
1039 * numbers.c (scm_fuck): Procedure removed; looks like old test
1041 * numbers.h: Prototype removed.
1043 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
1045 * debug.h (scm_debug_frame): Change `vect' member from an in-line
1046 array to a pointer, to match my Nov 21 change in eval.c.
1048 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1050 * libguile.h: Added #include "libguile/backtrace.h", #include
1051 "libguile/stacks.h".
1053 * strings.c (scm_string scm_make_string scm_string_ref
1054 scm_string_set_x scm_string_equal_p scm_string_append):
1055 Bugfix according to scm patch from Aubrey Jaffer:
1056 Corrected long-standing
1057 (not (eqv? (integer->char 128)
1058 (string-ref (make-string 1 (integer->char 128)) 0)))
1059 bug found by John Kozak <jk@noontide.demon.co.uk>.
1061 * strports.c, strports.h: Make scm_eval_0str return the value of
1062 the last expression evaluated (previously, it returned void).
1064 * strports.c, strports.h: New function: scm_read_0str. Does what
1067 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1069 * simpos.c (scm_getenv): return #f if string can't be found in the
1070 environment instead of throwing an exception, for compatibility
1071 with numerous other systems.
1073 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
1075 * Makefile.am (.c.x): Use guile-snarf.
1076 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
1078 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
1080 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1082 * backtrace.c (scm_display_error_message): Made non-static, and
1083 renamed from display_error_message.
1084 * backtrace.h (scm_display_error_message): Added extern decl.
1085 * throw.c (uncaught_throw): Use it to display the error message.
1087 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
1089 * inet_aton.c: Use #if 0, not #ifdef 0.
1091 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
1093 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
1094 to convert the returned value.
1095 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
1096 the offset argument.
1098 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1100 Add new interface to catch/throw, usable from C as well as
1102 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
1103 (scm_internal_catch): New function, replaces...
1104 (scm_catch_apply): Deleted.
1105 * throw.c (scm_catch_apply): Deleted; replaced with a more general
1106 mechanism which is a bit more code, but can be used nicely from C
1107 and implement the Scheme semantics as well.
1108 (scm_internal_catch): This is the replacement; it's named after
1109 the analogous function in Emacs.
1110 (scm_catch): Reimplemented in terms of the above.
1111 (struct catch_body_data, catch_body, catch_handler): New
1112 functions, used by scm_catch.
1113 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
1114 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
1115 support for new cwdr.
1117 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
1120 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
1122 * acconfig.h: Added DYNAMIC_LINKING symbol.
1123 * configure.in: Add option and checks for dynamic linking.
1124 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
1125 dynl.h: New files for dynamic linking support.
1126 * Makefile.am (libguile_a_SOURCES):
1128 (modinclude_HEADERS): Added "dynl.h".
1129 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
1131 * init.c (scm_boot_guile_1): Call
1132 scm_init_dynamic_linking to initialize dynamic linking support.
1134 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
1136 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
1137 (as we Schemers say). It needs to be global, so that I can tweak
1138 it for the proper operation of unexec.
1139 (scm_boot_guile_1_live): New variable, see above.
1141 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
1143 * guile-snarf.sh: Removed.
1144 * PLUGIN/guile.libs: Added dependency for -lm.
1145 * acinclude.m4: Renamed from aclocal.m4.
1146 * PLUGIN/greet: Removed.
1147 * Makefile.am, aclocal.m4: New files.
1148 * configure.in: Updated for Automake.
1150 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
1152 * eval.c (scm_definedp): Use top_level_lookup_closure_var
1153 and not top_level_lookup_thunk_var.
1155 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
1157 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
1159 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
1161 * eval.c (scm_definedp): Incompatibly changed to be a builtin
1162 Scheme function, instead of syntax. Single argument is now a
1165 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1167 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
1168 scm_ra_divide): Properly terminate statements passed as arguments
1169 to IVDEP macros. (Thanks to Bernard Urban.)
1171 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
1172 with non-constant sizes. (Thanks to Bernard Urban.)
1174 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1176 It's an "eval closure", not an "eval thunk." A thunk is a
1177 function of no arguments.
1178 * root.h (struct scm_root_state): Renamed
1179 top_level_lookup_closure_var from top_level_lookup_thunk_var.
1180 (scm_top_level_lookup_closure_var): Renamed from
1181 scm_top_level_lookup_thunk_var.
1182 * root.c (mark_root): Uses changed.
1183 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
1184 * init.c (scm_start_stack): Uses changed.
1185 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
1186 Change scheme-visible name to *top-level-lookup-closure* from
1187 *top-level-lookup-thunk*.
1189 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
1191 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
1192 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
1194 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
1196 * gc.c (struct scm_heap_seg_data): Doc fixes.
1198 * gc.c (scm_gc_sweep): Empty all segments' freelists before
1199 sweeping. Then, prepend each segment's free cells to its
1200 freelist, rather than wiping out the old value. (Thanks to Marius
1203 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
1204 scm_check_freelist, scm_debug_newcell): New functions and
1205 variables, for debugging freelist problems.
1206 * pairs.h (SCM_NEWCELL): New debugging version added.
1207 * gc.h (scm_debug_newcell): Added extern declaration, used by
1208 debugging version of SCM_NEWCELL.
1210 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1212 On some systems <libc.h> conflicts with <unistd.h>, and should not
1213 be #included at all.
1214 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
1215 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
1216 * configure.in: Call it.
1217 * posix.c, filesys.c: Use its results to decide whether or not to
1219 * configure, scmconfig.h.in: Rebuilt with autoconf and
1222 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1224 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
1225 pointer to the stdio stream before calling scm_setbuf0, so the
1226 latter will be able to retrieve it. I'm surprised this didn't
1227 segfault earlier. (Thanks to Christopher Lee.)
1229 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1231 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
1234 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1236 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
1237 number of stack narrowing specifier pairs. The first specifier in
1238 a pair controls inner border, the second the outer border. A
1239 number means cut that number of frames, a procedure object means
1240 cut until that object is found in operator position in a frame.
1242 * root.c (cwdr): Bugfix.
1244 * read.c: Recording of positions disabled by default.
1246 * procs.c (scm_closure_p): New function.
1248 * posix.c (scm_tmpnam): New function.
1250 * load.c: Added #include "throw.h".
1251 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
1254 * load.c, load.h (scm_read_and_eval_x): New function.
1256 * eval.c: Renamed debug option "deval" to "debug".
1258 (scm_eval_x): `eval!' is no longer accessible from the scheme
1259 level. Motivation: We can't allow operations which introduce
1260 glocs into the scheme level. Guile's type system can't handle
1261 these as data. Use `eval' or `read-and-eval!' as replacement.
1263 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
1264 SCM_CONSP since this is a macro!; Set vframe.prev to
1265 scm_last_debug_frame instead of 0. In this way we can look
1266 "above" the virtual start stack frame if we wish.
1267 (scm_debug_hang): New function: Useful for debugging Guile in
1268 certain tricky situations. Will probably be removed later...
1270 * debug.h: Changed semantics of debug option "backtrace". This
1271 option now only indicates whether we want automatic backtrace at
1274 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1276 * ports.c: #include "filesys.h"
1277 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
1279 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
1280 Motivation: This is system specific code which is related to file
1281 I/O. It also may use select. Added code by Gary Houston to
1282 detect presence of character in stdio buffers.
1284 * libguile.h: #include "libguile/libpath.h"
1286 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
1287 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
1288 SCM_SITE_DIR; Install libpath.h among the other include files.
1290 * load.c, load.h (scm_sys_package_data_dir): New function.
1292 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1294 * stacks.h: Bugfix: Don't use tail-array length field as stack
1295 length field! This screwed GC.
1297 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1299 * _scm.h: Added #ifndef around definition of macros min and max.
1301 * __scm.h: Added hooks for threads to plugin to in ints protection
1302 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
1303 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
1304 the main code in these macros duplicated and spread over multiple
1305 files. Renamed SCM_THREADS_SWITCHING_CODE ->
1306 SCM_THREAD_SWITCHING_CODE.
1308 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
1310 * snarf.h: New file.
1311 * guile-snarf.sh: New file.
1312 * Makefile.in (inner_h_files): Added snarf.h
1313 (ancillary, install, uninstall, distclean): Added actions for
1315 (.c.x): Use guile-snarf.
1316 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
1317 (gen_c_files): Note that these depend on guile-snarf.
1318 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
1319 now in "snarf.h". Added #include "snarf.h" to get them.
1320 * libguile.h: Added #include "snarf.h".
1321 (Patches applied and tweaked by Jim Blandy.)
1323 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1325 * socket.c: Use K&R style declaration for 'close'; the GNU coding
1326 standards suggest against providing prototypes for system
1327 functions. Thanks to Greg Troxel.
1329 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1331 * strports.c (scm_eval_0str): New function.
1332 #include "read.h", to get prototype for scm_read.
1333 * Makefile.in (strports.o): Update dependencies.
1334 * strports.h: New prototype.
1336 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
1337 scheme name from "int?" to "integer?". It seems to do the job.
1338 * numbers.h: Rename prototype too.
1339 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
1342 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
1343 scm_num_eq_p): Rename these according to R4RS conventions: call
1344 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
1345 to making libguile R4RS compliant without ice-9...
1347 * load.c (scm_sys_search_load_path): Search for files under all
1348 extensions listed in the %load-extensions variable. If FILENAME
1349 is absolute, return it unchanged, without searching the load path.
1350 (scm_loc_load_extensions): New variable, pointing to
1351 %load-extensions' value cell.
1352 (scm_init_load): Initialize it, and the value it points to.
1353 (scm_primitive_load_path): Improve error reporting.
1355 * load.c (scm_loc_load_hook): New variable, pointing to value cell
1356 of new Scheme variable %load-hook.
1357 (scm_primitive_load): Apply %load-hook to filename.
1359 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
1361 * configure.in: add tests for figuring out whether buffered data
1362 is available in a FILE structure, which is needed by char-ready.
1364 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
1367 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
1368 exceptions using misc_error instead of syserror. It seems a bit
1369 odd to throw an exception if a string can't be found in the
1370 environment, but it's consistent with open-file, stat etc.
1371 (simpos.h): remove sys_ from getenv.
1373 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
1374 occurs, throw an error instead of returning errno. Return value
1376 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1378 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1380 * filesys.c (scm_stat2scm): derive file type and permissions from
1381 the stat mode and append them to the returned vector.
1382 There isn't much overhead in doing this and it avoids the need to
1383 work with S_IRUSR et al. in Scheme.
1384 Define symbols scm_sym_regular etc.
1385 (scm_init_filesys): don't intern S_IRUSR etc.
1387 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1388 and s_primitive_load_path.
1390 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1392 * error.h: don't declare error symbols. prototype for scm_misc_error.
1394 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1397 * error.c: use SCM_SYMBOL to set up error keys.
1398 scm_misc_error: new procedure.
1400 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1402 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1403 between `#!' and `!#' is ignored.
1404 (skip_scsh_block_comment): New function.
1406 * feature.c (scm_set_program_arguments): New argument, FIRST.
1407 * feature.h: Update prototype.
1408 * init.c (scm_boot_guile_1): Pass new argument to
1409 scm_set_program_arguments.
1411 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1413 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1414 (scm_boot_guile): Call scm_set_program_arguments here, later than
1415 the old initialization.
1417 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1418 initialization procedure.
1419 - Delete in, out, err arguments; there are other perfectly good
1420 ways to override these when desired.
1421 - Delete result argument; this function shouldn't ever return.
1422 - Rename init_func argument to main_func, for less confusion.
1423 - Delete boot_cmd argument; main_func is more general.
1424 -Add 'closure' argument, to help people pass data to main_func
1425 without resorting to global variables.
1426 - Abort if reentered; don't bother returning an error code.
1427 - Call scm_init_standard_ports to set up the default/current
1428 standard ports; no need to pass them to scm_start_stack.
1429 - Remove code to evaluate the boot_cmd, and start the repl; let
1430 the user do something like that in main_func if they want.
1431 - Remove code to package up a return value; main_func can do any
1433 - Call exit (0), instead of returning.
1434 (scm_start_stack): Don't initialize the I/O ports here; that's
1435 weird. Delete in, out, err arguments. Move guts to
1436 scm_init_standard_ports, scm_stdio_to_port.
1437 (scm_init_standard_ports): New function, to set up current and
1438 default standard ports.
1439 (scm_start_stack, scm_restart_stack): Make these static.
1440 * init.h (scm_boot_guile): Adjust declaration.
1441 (scm_start_stack, scm_restart_stack): Remove externally
1442 visible declarations for these.
1443 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1445 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1446 written out several times in scm_start_stack.
1447 * fports.h: New declaration for the above.
1449 * feature.c (scm_set_program_arguments): New function.
1450 * feature.h: New declaration for the above.
1452 * ports.c: Formatting tweak.
1454 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1456 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1457 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1458 for obtaining the address of a car or cdr field. Motivation:
1459 &SCM_CXR make assumptions about the internal structure of the
1462 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1463 Motivation: see SCM_CXRLOC.
1465 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1466 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1467 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1468 Motivation: Safer use. Some other macros are defined in terms of
1469 these operations. If these are defined using the SCM_SETCXR
1470 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1471 to inefficiency and an <e1> with side-effects could potentially
1472 break. Also, these particular operations are heavily utilized in
1473 the garbage collector. In unoptimized code there will be a
1476 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1477 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,

1481 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1482 vports.c: Cleaned up use of pairs: Don't make any special
1483 assumptions about the internal structure of selectors and
1484 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1485 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1486 (Among other things, this change makes it easier to build Guile
1487 with certain compilers which have problems with casted lvalues.)
1489 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1491 * stacks.c: Improve selection of relevant stack frames when making
1492 a stack object. Introduce one level of indirection in the stack
1493 object to make it possible to "narrow" to a certain region of the
1494 stack. This facilitates making use of more clever algorithms (not
1495 implemented) for selecting relevant frames and gives a cleaner
1496 design since selection of frames can be done independently of
1497 extraction of frames from the real stack.
1498 (scm_stack_id): Also take #t as argument which means look at
1501 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1502 Turn n_tail into an integer directly representing current number
1503 of frames in stack. Add field tail.
1505 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1507 * debug.c (scm_make_memoized): Made it available at scheme level.
1508 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1509 SCM_NIMP before applying heavier predicates in argument checking.
1510 (scm_local_eval): Also take memoized object as argument.
1512 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1513 aren't created with zero length, but should such a strange
1514 creature suddenly turn up...
1516 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1518 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1519 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1521 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1523 * variable.c (scm_make_variable): Make the name hint optional, as
1525 (anonymous_variable_sym): Renamed from variable_sym. All uses
1528 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1529 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1530 of scm_primitive_load_path was also changed to
1531 "primitive-load-path", from "%try-load-path". Callers changed.
1532 We'd like to respect the convention that a function named
1533 "try-mumble" should behave just like the function called "mumble",
1534 but return #f instead of signalling some error.
1535 * load.h: Rename prototypes.
1537 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1539 * print.c (make_print_state, grow_print_state), print.h: Modified
1540 the print state representation: Don't use a tail array for
1541 recording of circular references. Resizing of the print state
1542 structure invalidates the print state pointer. To avoid passing
1543 around an indirect print state reference to all printing
1544 functions, we instead let the print state reference a resizable
1547 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1549 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1550 Don't crash when passed an improper list terminated by a
1551 non-immediate value.
1553 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1555 Allocate data for structures on an eight-byte boundary, as
1556 required by the tagging system.
1557 * struct.c (alloc_struct): New function.
1558 (scm_make_struct, scm_make_vtable_vtable): Call it.
1559 * struct.h (scm_struct_n_extra_words): Bump to 3.
1560 (scm_struct_i_ptr): New "field".
1561 * gc.c (scm_gc_sweep): When we need to free the data, use the
1562 information stored by alloc_struct to find the beginning of the
1563 block allocated to the structure, so we can free it.
1565 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1567 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1570 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1571 (scm_debug_info): New member: id.
1573 * stacks.c: Stacks are now represented as structs; Stacks have an
1574 id given to them by `start-stack'.
1575 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1577 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1578 Changed stack representation.
1580 * debug.c (scm_procedure_name): Try procedure property `name' for
1581 compiled closures aswell.
1583 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
1585 * eval.c: scm_i_name moved to gsubr.c
1586 (scm_m_define): Record names of all kinds of procedure
1587 objects. (Earlier, only closures were recorded.)
1589 * procprop.h: Added declaration of scm_i_name.
1591 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1592 (scm_make_gsubr): Record names of compiled closures.
1594 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1596 * debug.c, debug.h: Removed obsolete code.
1598 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1599 stacks.c: Renamed regs --> scm_contregs.
1601 * print.c (scm_free_print_state): Cleanup print state before
1602 returning it to pool. It is better to do it here than in
1603 scm_prin1 since scm_prin1 is called often.
1605 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1606 s_set_source_property_x): Check that first argument is a pair or a
1609 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1610 scm_i_line, scm_i_column and scm_i_breakpoint global.
1612 * init.c: Added #include "backtrace.h" and #include "stacks.h".
1613 (scm_boot_guile_1): Added calls to scm_init_backtrace and
1616 * debug.h: Added debug object smob declaration and macro
1619 * configure.in: Build with backtrace.o and stacks.o if debug
1622 * Makefile.in: Added entries for new files: backtrace.c,
1623 backtrace.h, stacks.c and stacks.h.
1625 * symbols.c (scm_sym2ovcell): Fixed documentation.
1627 * _scm.h (min, max): Added.
1629 * async.c: Moved `min' macro to _scm.h.
1631 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1632 SCM_BACKTRACE_INDENT.
1634 * eval.c: Added new debug options `maxdepth' and `indent'.
1636 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
1638 * print.h: Added selector SCM_PRINT_STATE.
1640 * print.c: New functions: scm_make_print_state,
1641 scm_free_print_state.
1643 * print.h: Added declarations for scm_make_print_state,
1644 scm_free_print_state.
1646 * debug.c (scm_m_start_stack): New acro.
1648 * debug.h: Small cleanup.
1650 * init.c (scm_boot_guile_1): Moved scm_init_debug below

1675 declare functions with prototypes. (Patch thanks to Marius
1678 More prototype-related changes from Marius Vollmer:
1679 * gdb_interface.h: Wrapped header file in #ifdef/#endif
1680 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
1681 * ports.h (ptobfuns): Added prototypes. This means some casting in
1683 * fports.c: Added casts for initializations, since the functions
1684 are defined to take FILE * as their stream argument, not SCM.
1685 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
1686 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
1687 to `char *str_data' to conform to prototype.
1689 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1691 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
1693 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
1695 * stime.c, stime.h: use SCM_P method.
1697 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1699 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
1700 be given at least two arguments. Insist that lst's last element
1701 be a list, but don't make any requirements of its predecessors.
1703 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1705 * eval.c (scm_nconc2last): Revert last change; there seems to be
1706 other stuff going on here.
1708 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1710 * eval.c (scm_nconc2last): Make sure that each element of lst
1711 (which is a list of argument lists, except for the tail) is a
1712 proper list, i.e., finite and terminated by '().
1714 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1716 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
1719 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
1720 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
1723 * vectors.c (scm_make_vector): Fill vectors with the undefined
1724 value, to help make Guile Scheme code more portable to other
1727 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
1728 * symbols.h, tags.h: Doc fixes.
1730 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
1732 * async.c (scm_take_signal): Doc fixes.
1734 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
1736 * numbers.c (scm_divbigint): When the remainder is zero, we don't
1737 want to subtract it from the modulus; we just want to leave it
1740 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
1742 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
1745 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
1747 * throw.c (scm_catch_apply): Finished implementation of
1750 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
1752 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
1754 (scm_init_filesys): set "i/o-extensions" feature.
1757 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
1759 * Makefile.in (root.o): Correct dependencies.
1761 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
1763 * Makefile.in: Added dependency entry for root.o.
1765 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
1766 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
1768 * init.c (scm_start_stack): Set initial root continuation number
1771 * procs.c: New function: scm_thunk_p.
1773 * procs.h: Added declarations of scm_thunk_p.
1775 * root.c: Renamed `call-with-new-root' -->
1776 `call-with-dynamic-root'.
1777 (cwdr): Removed allocation of new root state. This should be done
1778 separately by use of scm_make_root.
1779 (scm_apply_with_dynamic_root): New function: Does what it
1780 sounds like. Needed when spawning threads.
1782 * root.h: Added member last_debug_frame to root state.
1783 Added #include "libguile/debug.h"
1785 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
1786 arguments. The motivation is that code in root.c needs catch
1787 functionality, and we want to avoid code duplication.
1788 New functions: scm_catch, scm_lazy_catch. These are wrappers for
1789 scm_catch_apply. scm_lazy_catch is intended to introduce catch
1790 handlers that run without popping the stack into the dynwind
1793 * throw.h: Added prototypes for scm_catch_apply and
1796 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1798 * root.h (scm_root, scm_set_root): Decouple thread support details
1799 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
1800 SCM_SET_THREAD_LOCAL_DATA.
1802 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
1803 and tortoise scanning loop.
1805 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
1807 * Makefile.in: Rebuild dependencies.
1809 * libguile.h: #include "libguile/print.h" before "smob.h", since
1810 the latter uses the print_state structure.
1812 * throw.c (scm_ithrow): Use the correct variable when checking to
1813 see if a given element of scm_dynwinds is a valid catch.
1815 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
1816 structure, abort; don't just silently ignore the garbage.
1818 * _scm.h: #include "print.h" here, since it seems to be used just
1820 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
1821 strports.c, unif.h: Don't #include "print.h".
1823 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1825 * feature.h (scm_loc_features): Removed external declaration.
1826 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
1828 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1830 * feature.c (scm_init_feature): Added threads feature (needs to be
1831 initialized here, since features doesn't exist when
1832 scm_init_threads is called).
1834 * libguile.h: Added #include "libguile/../threads/threads.h".
1835 (This is a kludge to get thread support working. This should be
1838 * configure.in, acconfig.h: Added flags for thread support.
1840 * scmsigs.c: Define `signal' to be `pthread_signal' if using
1843 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
1844 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
1847 * _scm.h: Added conditional #include "threads.h"
1849 * __scm.h (SCM_ASYNC_TICK): Added call to macro
1850 SCM_THREADS_SWITCHING_CODE.
1852 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
1853 allocate the basic dynamic root object.
1854 (scm_boot_guile): Added call to scm_init_root.
1856 * root.c, root.h: Added root smob.
1857 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
1858 functions: Implements dynamic roots mostly according to spec in
1859 SCM manual. Main difference is that the second argument is a
1860 throw handler rather than an error "thunk".
1862 * root.h: Added declaration of scm_init_root.
1864 * root.c: Added #include "genio.h", #include "smob.h", #include
1865 "pairs.h", #include "throw.h", #include "dynwind.h", #include
1867 (scm_init_root): Added #include "root.x".
1869 * throw.c: Added #include "stackchk.h"
1870 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
1871 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
1872 can be used in scm_call_with_new_root; Added reenabling of stack
1873 checking when catching a throw.
1875 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
1877 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
1879 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
1880 element is not found, as per R4RS.
1882 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1884 * list.c: Doc fixes throughout.
1886 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1888 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
1889 declare the char * to be const. Avoids a warning in rgx.c.
1891 * ports.h: spelling fix.
1893 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
1896 * load.c (scm_sys_try_load_path): throw an error if file not found
1897 (like it says it in NEWS).
1899 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1901 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
1902 PROPS slot to '(), not #f; it's an empty alist.
1904 * throw.h, throw.c: Use SCM_P instead of #if hair.
1906 Remove special support for uncaught throws; see throw.c for
1908 * throw.c (uncaught_throw): New function.
1909 (scm_ithrow): Call uncaught_throw if we don't find a throw
1910 target; don't mess with scm_bad_throw_vcell.
1911 (scm_bad_throw_vcell): Variable deleted.
1912 (scm_init_throw): Don't initialize it.
1914 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
1917 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1919 * numbers.c (scm_istr2int): If the number is short (as most
1920 numbers are), just call scm_small_istr2int to deal with it.
1921 (scm_small_istr2int): New function, created by un-#ifdefing the
1922 non-bignum version of scm_istr2int and renaming it.
1924 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
1926 * load.c (scm_sys_try_load): don't check whether value returned
1927 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
1928 Change the Scheme name from %try-load to primitive-load.
1930 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
1931 Can avoid passing a message, allowing it to be derived in the
1932 error handler (e.g., if we want to throw to the key both from
1935 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
1937 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
1938 references now have a new appearance which is more compact and
1939 also gives a clue about what the target of the reference is.
1940 By setting parameters in the print state, more fancy printing can
1941 be achieved. This is used by the (not yet commited) backtrace
1944 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
1946 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
1949 * print.c: Added #include "struct.h". Removed function
1952 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
1953 scm_iprin1. Removed prototype for scm_prlist.
1955 * arbiters.c (prinarb),
1956 async.c (print_async),
1957 debug.c (prindebugobj, prinmemoized),
1958 eval.c (prinprom, prinmacro),
1959 filesys.c (scm_fd_print, scm_dir_print),
1961 mallocs.c (prinmalloc),
1962 numbers.c, numbers.h (scm_floprint, scm_bigprint),
1963 smob.h (scm_smobfuns),
1964 srcprop.c (prinsrcprops),
1966 unif.c, unif.h (scm_raprin1, rapr1),
1967 variable.c (prin_var): Changed argument `int writing' to
1968 `scm_print_state *pstate'.
1970 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
1971 that it will be called before scm_init_print.
1973 * print.c (scm_prin1): Print states are now allocated when calling
1974 scm_prin1 and then passed around to all printing functions as an
1975 argument. A cache `print_state_pool' enables reuse of print
1977 (scm_make_print_state): New function.
1978 (scm_iprin1): Adaption to print states.
1979 (scm_iprlist): An initial "hare and tortoise" scan brings down
1980 time complexity to O (depth * N). (Better time complexity will be
1981 achieved when the printing code is completely rewritten.)
1983 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1985 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
1986 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
1987 it gets done whether or not the cache variable has a value.
1989 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
1991 Distinguish #f and ().
1992 * __scm.h: #undef SICP.
1993 * pairs.h (SCM_EOL): Delete this definition, equating it with
1995 * tags.h (SCM_EOL): Give it a new definition here; I think I found
1996 the value it used to have. Doc fixes, too.
1998 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
2000 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
2001 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
2002 Lord's implementation of structs, allowing for tail arrays as
2003 described in the manual. Also fixed some bugs. (Both the interface
2004 and the implementation should be improved.)
2006 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
2008 * print.c, print.h: Closures now print like #<procedure foo (x)>.
2009 People who whish to see the source can do `(print-enable 'source)'.
2010 Removed #ifdef DEBUG_EXTENSIONS.
2012 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2014 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
2015 integer (assuming for now accepting an integer is a good thing).
2017 * error.c, fports.c: replace use of %S in lgh_error args with %s.
2018 %S will be used instead for write'ing arguments.
2020 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
2021 asserts. fix a few other asserts.
2022 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
2023 scm_uniform_vector_ref, scm_array_set_x,
2024 scm_dimensions_to_unform_array): change args in
2025 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
2026 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
2027 scm_substring_fill_x): likewise.
2028 gsubr.c (scm_gsubr_apply): likewise.
2029 eval.c (SCM_APPLY): likewise.
2031 * eval.c (4 places): replace scm_everr with lgh_error or
2034 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
2035 scm_memory_error): new procedures.
2036 scm_everr: deleted. can use scm_wta, dropping first two args.
2037 scm_error: convert NULL subr to SCM_BOOL_F.
2039 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
2042 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
2045 * error.c, error.h: new error keys: scm_arg_type_key,
2046 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
2048 scm_wta: reimplement using lgh_error instead of scm_everr.
2050 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
2052 * gdbint.c: scm_lread now has one more argument.
2054 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
2055 scm_port_\1; Added mutator scm_set_port_filename_x (used when
2056 loading source from non-file ports, which, e. g., happens when
2057 using the Emacs interface).
2059 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
2062 * read.c: Added code for recording of positions of source code
2063 expressions; New functions: recsexpr, scm_lreadrecparen;
2064 _scm_make_srcprops --> scm_make_srcprops
2065 (scm_flush_ws): Removed updating of positions counters. This work
2066 is already done by scm_gen_getc
2068 * read.h: Added prototype for scm_lreadrecparen
2070 * print.c: Added #include "alist.h"
2072 * eval.c: Added #include "hash.h"
2074 * eq.c: Added #include "ramap.h"
2076 * options.c: Documentation fixes.
2078 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
2079 (scm_init_srcprop): Adjusted size of initial source-whash. Name
2080 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
2081 --> scm_make_srcprops
2083 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
2084 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
2085 function calls in the definition of the whash access macros.
2087 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
2089 * init.c (scm_boot_guile): Add level of indirection to
2090 scm_boot_guile_1() to ensure that stack base pointer is properly
2091 initialized. There was no guarantee that variable i was the
2092 highest/lowest variable on stack (i.e. the call frame of
2093 scm_boot_guile was not completely protected from gc).
2095 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
2097 * ports.h (scm_port_table): put back file_name, it will be used to
2098 support debugging. Undo related changes in fports.c, ioext.c,
2101 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2103 * ports.h (scm_port_table): remove file_name member for now, it seems
2105 * fports.c (scm_open_file): don't set file_name in PTAB.
2106 (prinfport): don't use file_name in PTAB.
2107 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
2108 * ports.c (scm_add_to_port_table): don't intialize file_name.
2109 (scm_port_file_name): remove for now.
2110 * gc.c (scm_gc_mark): don't mark PTAB file_name.
2112 * fports.h (scm_mkfile): prototype deleted.
2113 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
2115 * debug.c, unif.c: use scm_out_of_range instead of
2116 wta for range errors (ASSERT still needs work).
2118 * error.c, error.h (scm_out_of_range): new procedure.
2120 * error.c, error.h (scm_out_of_range_key): new key.
2122 * posix.c (scm_sync): #else was missing.
2124 * error.c, error.h: append _key to names scm_num_overflow and
2127 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
2128 of consing an empty list.
2129 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
2130 of macros, saves code and string space.
2131 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
2132 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
2133 lower case. Rename scm_syserror_m to scm_syserror_msg.
2134 error.h: prototypes for new procedures.
2136 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
2138 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
2140 * error.c, error.h: setup scm_num_overflow key.
2142 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
2143 Remove definition of SCM_OVSCM_FLOW.
2145 * fports.c (scm_open_file): use SCM_SYSERROR_M.
2147 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
2148 explicit message and args.
2150 * error.c, error.h, __scm.h: change system_error_sym to
2153 * error.c (system_error_sym): remove leading %% from the Scheme name
2156 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
2158 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2160 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
2161 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
2162 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
2163 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
2164 renamed. (These were introduced by unsupervised name
2167 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2169 * print.c: Added code for detection of circular references during
2170 printing. (init_ref_stack, grow_ref_stack): New functions. Added
2171 a hook for printing of closures (accessible via print options).
2172 This leads to a split of calls to scm_iprin1 into two classes:
2173 elementary print operations (e. g. the code which prints a smob)
2174 still use scm_iprin1 while top level calls (like scm_display) use
2175 scm_prin1. scm_prin1 begins by clearing the data structure used
2176 to record reference information.
2178 * print.h: Added declarations of scm_prin1 and scm_prlist.
2180 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
2182 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
2184 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
2186 * error.c (err_head): scm_iprin1 --> scm_prin1
2188 * debug.c: Adjusted header comment.
2192 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2194 * strerror.c: Doc fix.
2196 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2198 * gdbint.c (gdb_read): Now possible to run during GC.
2199 (unmark_port, remark_port): New functions.
2201 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
2203 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
2204 of allocating a new string object. Also, increase size by
2205 the factor 2 instead of 1.5.
2207 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
2209 * __scm.h (SCM_P): Corrected to run under traditional C.
2211 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
2214 * async.c: Calls to scm_sysintern corrected.
2216 * async.h (scm_async_clock): Redundant declaration removed.
2218 * continuations.c (scm_dynthrow): Redundant declaration removed.
2220 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
2221 Definition typos corrected.
2223 * debug.h: Missing declarations of functions in debug.c added
2226 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2227 Missing declarations to functions in eval.c added.
2229 * filesys.c: Possibly uninitialized variable rv.
2231 * gc.h (scm_object_addr, scm_unhash_name): Missing
2232 declarations of functions defined in gc.c added.
2234 * genio.c: Possible typos str_data -> wstr_data. ???
2236 * genio.c: Possibly unintended shadowing of local variable
2237 `int c' (gotos out of scope of inner `c'). ???
2239 * init.c: Uninitialized `SCM last' may be used.
2241 * ioext.h: (scm_sys_isatty_p): Typo.
2243 * list.h (scm_list_head): Missing prototype for function in
2246 * numbers.c (scm_two_doubles): Changed from extern to static
2247 (is used only within numbers.c).
2249 * numbers.h: Repeated declarations removed.
2251 * ports.h (scm_close_all_ports_except): Declaration for the
2252 function defined in ports.c added.
2254 * posix.h: Missing declarations added.
2256 * procs.h (scm_make_subr_opt): Missing declaration added.
2258 * socket.h (scm_sys_gethost): Missing declaration added.
2260 * socket.h: Redundant declarations removed (they are in fdsocket.h).
2262 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
2263 Missing declarations added.
2265 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
2267 * struct.c: Uninitialized variable `SCM answer' may be used.
2269 * unif.c (l2ra): Declaration prototype.
2271 * unif.c (scm_array_equal_p): Dummy definition removed (it is
2272 defined in ramap.c).
2274 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
2275 Redundant declarations removed (they are in ramap.h).
2277 * variable.h (scm_make_udvariable,
2278 scm_make_undefined_variable): Declaration corrected to
2279 correspond variable.c.
2281 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
2282 Missing declarations added.
2284 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
2286 * Makefile.in (distclean): Don't forget to delete fd.h.
2288 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2290 * fd.h.in, tags.h: Trivial cleanups.
2292 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
2293 marksweep.h just declared functions from gc.c.
2294 * gc.h, libguile.h: Don't #include "marksweep.h".
2295 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2296 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
2297 dependencies updated.
2299 * libguile.h: Don't #include "files.h"; it's been deleted.
2301 * files.c (scm_sys_delete_file): Moved to filesys.c.
2302 File is now empty; deleted.
2304 * filesys.c: scm_sys_delete_file is now here. Remove
2305 #if's; they seem to rely on remnants of an old portability
2306 regimen. If the problems come up again, solve them properly,
2307 using autoconf. Specifically: Don't test M_SYSV, and #define
2308 remove to be unlink if it's #defined; don't use remove just
2309 because HAVE_STDC_HEADERS is #defined.
2310 * filesys.h: Add declarations for scm_sys_delete_file.
2311 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2312 files.o, files.h, files.c, and files.x.
2313 * init.c: Don't #include "files.h", and don't call scm_init_files.
2315 Use SCM_P instead of PROTO; the latter intrudes on the user's
2317 * params.h: Deleted; definition of SCM_P moved to...
2318 * __scm.h: ... here, where it replaces PROTO macro.
2319 * libguile.h, smob.h: Don't #include "params.h".
2320 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
2321 smob.h: Fix prototypes accordingly.
2322 * Makefile.in: Update dependencies.
2323 (inner_h_files): Remove params.h.
2325 * gc.c: #include "gc.h"; every module should include its header,
2326 to let the compiler cross-check the declarations against the
2329 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2330 simpos.h: #include "libguile/__scm.h".
2332 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2334 * init.c: Don't forget to #include smob.h and init.h.
2335 * Makefile.in: Dependencies updated.
2337 * smob.h: Use PROTO instead of #if __STDC__.
2339 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2341 * __scm.h: Doc fixes.
2343 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2344 <angles>; this allows `make depends' to work properly.
2346 * libguile.h: #include smob.h and pairs.h before the others; they
2347 define typedefs used by other headers.
2349 C files should #include only the header files they need, not
2350 libguile.h (which #includes all the header files); the pointless
2351 recompilation was wasting my time.
2352 * Makefile.in (all .o dependency lists): Regenerated.
2353 * libguile.h: Don't try to get a definition for size_t here...
2354 * __scm.h: Do it here.
2355 * _scm.h: Since this is the internal libguile header, put things
2356 here that all (or a majority) of the libguile files will want.
2357 Don't #include <libguile.h> here; that generates dependencies on
2358 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2359 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2360 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

2457 * weaks.c: Get "weaks.h".
2459 * stackchk.h: #include "libguile/debug.h",
2461 * print.h, read.h: #include "options.h", since everyone who uses
2462 either of these files will need that.
2464 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2465 anyone who uses this file will need them to define the smob
2466 printing functions. Also, get markers.h, since people will need
2467 to #define the mark functions.
2469 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2470 * ports.h: ... to here.
2472 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2473 don't rely on archaic C default type rules.
2475 * fports.h: #include "libguile/ports.h", since you need that in
2476 order to parse this.
2478 * genio.h: #include "libguile/print.h", because you need that to
2479 parse this; don't bother #including "ports.h", since print.h gets
2482 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2484 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2485 this; it's now a reference to an element of *scm_root.
2487 * debug.h: Don't #include "options.h"; the compiler won't be able
2488 to find that once the headers are installed; instead, #include
2489 "libguile/options.h".
2490 * gc.h: Same, with marksweep.h.
2491 * mbstrings.h: Same, with symbols.h.
2492 * scmhob.h: Same, with _scm.h.
2493 * smob.h: Same, with params.h.
2495 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2496 C files; there's no need for this, and it forces recompilations
2499 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2501 * error.c (scm_error): declare scm_error_callback.
2503 * error.h: prototype for scm_error_callback.
2505 * __scm.h: define lgh_error.
2506 (SCM_SYSERROR): redefine using lgh_error.
2508 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2510 * error.c (scm_error): new procedure.
2512 * error.h: prototype for scm_error.
2514 * Makefile.in (install): install scmconfig.h from the current
2515 directory, not $(srcdir).
2517 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2519 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2520 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2521 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
2522 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
2523 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,

2527 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2528 vports.h, weaks.h: #include "libguile/__scm.h", not
2529 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2530 dependencies are within libguile properly.
2532 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2534 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2535 when scmconfig.h doesn't exist.
2537 * load.c (scm_sys_try_load): Correct spelling.
2539 * feature.c (scm_loc_features): Make this static.
2541 * Makefile.in (libpath.h): Omit trailing slash from path. We
2542 shouldn't require it of users, so why put it here?
2544 Move code to initialize and search %load-path from ice-9 to C
2545 code, so we can use the load-path to find the ice-9 boot code;
2546 this makes it easier to run Guile without installing it. See
2547 corresponding changes in guile/Makefile.in.
2548 * feature.c: Move stuff concerned with the load path to load.c.
2549 (scm_compiled_library_path): Deleted.
2550 Don't #include libpath.h here.
2551 * feature.h: Don't mention scm_compiled_library_path.
2552 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2553 <sys/stat.h>, and <unistd.h> (if present).
2554 (R_OK): #define if the system hasn't deigned to.
2555 (scm_loc_load_path): New variable.
2556 (scm_init_load_path, scm_sys_search_load_path,
2557 scm_sys_try_load_path): New functions.
2558 (scm_init_load): Initialize scm_loc_load_path to point to the
2559 value cell of the Scheme %load-path variable.
2560 * load.h: Add declarations for scm_sys_search_load_path,
2561 scm_sys_try_load_path.
2562 * init.c: Call scm_init_load_path.
2563 * Makefile.in (feature.o, load.o): Dependencies updated.
2565 * load.c, load.h: Rewrite using PROTO macro.
2567 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2569 * gc.c (scm_cellp): New function: C predicate to determine if an
2570 SCM value can be regarded as a pointer to a cell on the heap.
2572 * gc.h: Added declaration of scm_cellp.
2574 * gdb_interface.h: New file: The GDB interface header from the GDB
2577 * gdbint.c: New file: GDB interface.
2579 * gdbint.h: New file: GDB interface.
2581 * libguile.h: Added #include <libguile/gdbint.h>.
2583 * init.c (scm_boot_guile): Added scm_init_gdbint.
2585 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2586 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2587 found if object files and source are kept separate).
2589 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2591 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2593 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2595 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2596 TK_SRC_DIR; they're not relevant any more.
2598 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2599 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2601 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2603 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2604 search path, so we can find the <libguile/MUMBLE.h> headers.
2606 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2608 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2609 implicit in the .c.o rule.
2610 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2613 Put the library path in a header file, instead of passing it on
2614 the command line in every compilation.
2615 * Makefile.in (libpath.h): New target.
2616 (feature.o): Depend on libpath.h.
2617 (clean): Delete libpath.h.
2618 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2619 * feature.c: ... #include "libpath.h" here.
2620 * .cvsignore: Ignore libpath.h.
2622 Don't install the unwashed masses of Guile header files in the
2623 main #include path; put most of them in a subdirectory called
2624 'libguile'. This avoids naming conflicts between Guile header
2625 files and system header files (of which there were a few).
2626 * Makefile.in (pkgincludedir): Deleted.
2627 (innerincludedir): New variable; this and $(includedir) are enough.
2628 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
2629 (installed_h_files): Divide this up. Now this variable lists
2630 those header files which should go into $(includedir) (i.e. appear
2631 directly in the #include path), and ...
2632 (inner_h_files): ... this new variable says which files appear in
2633 a subdirectory, and are referred to as <libguile/mumble.h>.
2634 (h_files): List them both.
2635 (install): Create innerincludedir, not pkgincludedir. Put
2636 the installed_h_files and inner_h_files in their proper places.
2637 (uninstall): Corresponding changes.
2638 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2639 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2640 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
2641 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
2642 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
2643 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2644 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2645 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2646 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2647 vports.h, weaks.h: Find __scm.h in its new location.
2648 * __scm.h: Find scmconfig.h and tags.h in their new locations
2649 (they're both "inner" files).
2651 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
2653 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
2655 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2657 * posix.c: Doc fixes.
2659 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
2661 * socket.c: Don't include a prototype for inet_aton; just use a
2662 K&R style declaration, to avoid warnings but minimize the chance
2663 of conflicts with the system.
2665 On NextStep, <utime.h> doesn't define struct utime, unless we
2666 #define _POSIX_SOURCE before #including it.
2667 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
2668 * acconfig.h: New comment text for above CPP symbol.
2669 * configure.in: Call it.
2670 * posix.c: #define _POSIX_SOURCE if it seems necessary.
2672 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
2674 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
2675 testing for __EMX__.
2677 * posix.c: #include <libc.h>, if it exists.
2679 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
2680 don't even know if the latter exists.
2682 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
2683 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
2684 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
2686 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
2688 (scm_init_posix): Use them when initializing the Scheme constants
2691 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2693 * Makefile.in (libdir, includedir, bindir): Use the
2694 autoconf-supplied values, instead of deriving them ourselves.
2695 (pkgincludedir, datadir, pkgdatadir): New variables.
2696 (install, uninstall): Put the header files in a special
2697 subdirectory, not in the main search path.
2699 * Makefile.in (ALL_CFLAGS): Provide the proper value for
2700 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
2702 * Makefile.in (IMPLPATH): Deleted; never used.
2704 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
2705 on the Tcl/Tk source any more.
2706 (INCLUDE_CFLAGS): Remove references to the above.
2708 * Makefile.in (version.o): Corrected dependencies.
2710 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
2712 * libguile.h: #include "version.h"
2714 * init.c (scm_boot_guile): Call scm_init_version.
2715 * gscm.c (gscm_run_scm): Call scm_init_version.
2717 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
2718 GUILE_VERSION): AC_DEFINE these.
2719 (acconfig.h): #undef the above symbols.
2721 * Makefile.in (libobjs): Add version.o.
2722 (installed_h_files): Add version.h.
2723 (c_files): Add version.c.
2724 (gen_c_files): Add version.x.
2725 (version.o): New rule.
2726 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
2727 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

2741 * version.c: New file.
2743 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2745 * symbols.c (scm_strhash): scm_downcase is now a function, not an
2746 array; use it appropriately. Since GCC is quite happy to
2747 subscript functions, it never warned us about this; we should use
2748 -Wpointer-arith in the future. I guess we never tested
2751 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2753 * socket.c: Doc and copyright fixes.
2755 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2757 * debug.c: Fixed and improved gdb support.
2759 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2761 * socket.c: Added declaration of inet_aton to avoid compiler
2762 warning. (Hope this solution is correct.)
2764 * stime.c: Added declaration of ftime. (This is missing in
2767 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
2769 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2771 * Makefile.in (c_files): add strerror.c.
2773 * strerror.c: new file from Emacs' sysdep.c.
2774 maybe configure should also check for sys_errlist.
2776 * configure.in (AC_REPLACE_FUNCS): add strerror.
2778 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2780 * debug.c (scm_init_debug): Added initialization for
2781 scm_evaluator_traps.
2783 * debug.h, debug.c: Various name changes.
2784 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
2785 "debug-options-interface". See commentary in options.c.
2787 * options.h, options.c: Options now have documentation strings.
2788 Also added a long explanatory commentary.
2790 * eval.c, print.h, print.c, read.h, read.c: Modifications to
2793 * gscm.c, init.c, root.c, throw.c: Bug fixes:
2794 last_debug_info_frame is now updated in all cases.
2796 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
2799 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2801 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
2802 Added option STACK_CHECKING.
2804 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
2806 * Makefile.in: Added {debug,options,srcprop}.{h,c}
2808 * __scm.h: Removed symbols for debugging support.
2810 * acconfig.h: Added symbols for debugging support.
2812 * configure.in: Added user option for debugging support.
2813 --enable-debug will include the debugging code into libguile.a.
2815 * continuations.c (scm_make_cont): Enlarged the #if 0 around
2816 scm_relocate_chunk_to_heap.
2818 * debug.c: New file: low-level debugging support. It also
2819 includes support for debugging with gdb. (The extensions to gdb
2820 are written by Per Bothner at Cygnus.)
2822 * debug.h: New file: low-level debugging support.
2824 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
2825 argument pairs. Extensive modifications to the debugging
2826 evaluator. Added "SECTION:" commentaries to clarify what happens
2827 when, during double compilation. Renamed EVALIMP --> EVALIM.
2828 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
2829 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
2830 the beginning of the file. New procedure: scm_unmemocopy.
2831 Added some global state variables needed by the debugging
2832 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
2833 check_entry, check_apply, check_exit, debug_options and
2834 evaluator_traps. New acro: undefine.
2836 * eval.h: Renamed EVAL --> XEVAL.
2838 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
2839 --> scm_make_weak_key_hash_table.
2841 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
2842 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
2844 * libguile.h: Conditionally include debug.h
2846 * objprop.c (scm_object_properties, scm_set_object_properties_x):
2847 scm_object_properties shouldn't return handle. `handle' now gets
2848 initialized in scm_set_object_properties_x. scm_object_properties
2849 doesn't any longer create an entry in scm_object_whash.
2851 * options.c: New file: handling of run time options.
2853 * options.h: New file: handling of run time options.
2855 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
2857 * print.c: New procedure: scm_print_options
2859 * print.h: Defines for print options.
2861 * read.c: New procedure: scm_read_options
2863 * read.h: Defines for reader options.
2865 * root.h: Added scm_source_whash among scm_sys_protects.
2867 * srcprop.c: New file: source properties.
2869 * srcprop.h: New file: source properties.
2871 * throw.c (jbsmob): Jump buffers are now correctly allocated.

2876 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2878 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
2880 * libguile.h: #include "objprop.h"; I guess this was forgotten.
2882 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
2883 and should be called by the final client.
2885 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
2887 * gc.h: Use the PROTO macro when declaring functions.
2888 * gc.c: Use the PROTO macro when declaring static functions.
2889 Remove the CPP hair around function definitions.
2891 * gc.c (scm_init_storage): Initialize scm_asyncs.
2893 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
2894 preprocessor symbol; "__scm.h" is where it might get #defined.
2895 * __scm.h: Similar: #include <scmconfig.h> before testing
2898 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
2900 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
2902 * init.c (scm_boot_guile): Add init_func argument; call
2903 (*init_func) instead of calling scm_appinit; it's ucky to
2904 hard-code names for the user's procedures.
2905 * init.h (scm_boot_guile): Adjust declaration.
2907 * __scm.h (PROTO): New macro, for declaring functions with
2910 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
2911 eliminate all the __STDC__ conditionals.
2912 (scm_boot_guile): Add declaration.
2913 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
2914 Remove __STDC__ conditionals around function definitions; the
2915 declarations in init.h will provide the same information, more
2918 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
2919 complain about it in the error message; the error message is
2920 adequate without that note, and there's nothing the user can do
2923 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
2925 * Makefile.in (ancillary): Drop def.sed.
2927 * posix.c (scm_init_posix): Use numeric values, rather than
2928 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
2929 F_OK. The symbols aren't available on some systems, and I'm
2930 pretty sure their values are fixed by common widespread practice.
2931 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
2933 More functions unavailable on some systems.
2934 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
2935 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
2937 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2938 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
2939 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
2940 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
2941 stub that signals an error as the #else.
2943 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
2945 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
2947 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
2949 * unif.c: include ramap.h.

2959 * configure.in: check for sys/ioctl.h.
2961 * ports.c: include <malloc.h> not "malloc.h".
2963 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2965 * fports.c: remove ttyname and tmpnam declarations.
2967 * posix.c: fewer ttyname declarations.
2969 * fports.c: include <string.h> not "string.h".
2971 * init.c, ioext.c: include string.h and unistd.h.
2973 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2975 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
2976 genio.c, simpos.c, vports.c: include string.h.
2978 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
2980 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
2982 (scm_addr_buffer_size): change type from scm_sizet to int.
2983 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
2984 from scm_sizet to int.
2986 * error.c: include unistd.h.
2988 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
2991 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
2993 * __scm.hd, def.sed: deleted.
2995 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
2997 Changes for NeXT, suggested by Robert Brown.
2998 * configure.in: Call AC_TYPE_MODE_T.
2999 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
3000 NeXT. Put header file list in alphabetical order.
3001 * configure, scmconfig.h.in: Regenerated.
3002 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
3004 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
3007 * acconfig.h: New file, providing documentation for the CPP
3008 symbols defined in configure.in
3009 * acconfig-1.5.h: Removed; superceded by the above.
3011 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
3013 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
3015 * fports.c (scm_open_file): don't return #f, throw error.
3017 * ioext.c (fileno): renamed from %fileno.
3018 (soft-fileno): deleted.
3020 * ports.c (scm_port_revealed): don't need to check for -1 from
3022 (scm_set_port_revealed_x): return unspecified, not #f.
3024 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
3026 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
3028 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
3030 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
3032 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3034 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
3035 This is necessary on Ultrix, and doesn't hurt portability.
3037 * Makefile.in (dist-dir): New target, implementing a new dist system.
3038 (installed_h_files): Put in alphabetical order.
3039 Remove duplicate entries for markers.h and unif.h.
3040 (c_files): Remove duplicate entries for markers.c.
3041 (ancillary): Renamed from anillery; all uses changed. Remove
3042 PLUGIN; it's a directory, and needs special treatment in dist-dir.
3043 Remove all the ../doc/* files; doc/Makefile.in handles that.
3045 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
3047 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
3048 every if must have an else, or else the whole command has a
3049 non-zero exit code whenever the if's condition is false.
3051 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
3053 * posix.c: include string.h.
3055 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
3057 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
3060 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
3061 Remove leading % from scheme names.
3062 Do not return error values, call SCM_SYSERROR or similar.
3064 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
3066 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
3068 * struct.c (scm_init_struct): new file.
3070 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
3072 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
3073 (scm_list_head): added list-head for rapidly chopping argument
3074 lists off of longer lists (and similar).

3078 * objprop.c (scm_object_property): assq the cdr of the whash
3079 handle for obj, not the handle itself.
3081 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
3083 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
3084 weak hash tables last of all marking to avoid an obscure gc bug.
3085 WARNING: circular lists stored in a weak hash table will hose us.
3087 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
3089 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
3090 new functions similar to scm_substring_move_left_x and
3091 scm_substring_move_right_x.
3093 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
3095 * init.c (scm_boot_guile): prevent gc with scm_block_gc not

3100 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
3102 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
3104 * strports.c (scm_strprint_obj): convenience function. C for
3105 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))

3108 removed to a separate library
3110 * init.c (scm_boot_guile): copied from guile-tcl.c.
3111 Initialization specific to tcl interpreters removed.
3113 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
3115 * ports.c (scm_ports_prehistory): size malloced here doesn't
3116 matter so long as it is non-0 (got rid of "* 4").
3118 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
3120 * gscm.h: gscm_mkarray eliminated (presumably was not being used
3121 since its definition was bogus).
3123 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
3125 * mallocs.[ch]: back again (for rx at least).
3127 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
3129 * ports.c: removed functions relating to the mapping between ports
3130 and descriptors. (That stuff is unix-specific and should be collected
3131 in a separate library).
3133 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
3134 (Tom Mckay@avanticorp.com)
3136 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
3138 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
3139 handled correctly (SCM_FREEP was applied to them) -- test for
3140 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
3141 being overwritten with #f. (brown@grettir.bibliotech.com)
3143 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
3145 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs

3148 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
3150 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak

3160 Generalized assoc and hash-table functions.
3161 Factored pairs.c into multiple files.

3173 NOTE: don't use a alist here.
3174 (scm_set_procedure_properties_x): fix type checking throughout this file.

3184 * vports.c (scm_make_soft_port): allocate a port table entry
3185 (possibly triggering gc) before setting the tag of the corresponding
3188 * pairs.c (scm_delq_x): never throw an error.
3190 * vectors.c (scm_make_vector): made the default vector fill argument
3191 into '() (much more useful than the previous value, "#unspecified")
3193 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
3195 * ports.c (scm_add_to_port_table): Added fields
3196 to port table entries: file_name, line_num, col.
3197 Update these in open_file, gen_getc and gen_ungetc.
3198 Added procedures to access those fields.
3200 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
3202 * procs.c (scm_make_subr_opt): new entry point for making

3221 GC statistics keeping moved to gc.c.
3222 Other statistics keeping can be done from Scheme.
3223 REPLS are now written in Scheme.

3232 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
3234 * feature.c (scm_compiled_library_path): moved here from repl.c.
3235 This file is for stuff relating specifically to Scheme libraries
3238 * eval.c (scm_m_define): don't give warning about redefinition, don't
3241 NOTE: this should throw a resumable exception with parameters --
3242 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
3244 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
3246 * error.c: scm_warn eliminated.

3266 because it changes size.
3268 (stputc stwrite): check/change the strings length with interrupts
3271 * objprop.c (scm_set_object_property_x &c): use the generic
3272 hashing functions and be threadsafe.

3275 (per suggestion jaffer@gnu.ai.mit.edu).
3277 * mbstrings.c (scm_multi_byte_string): guard against argument list
3280 * strings.c (scm_make_string): loop cleanup

3296 functions. hash, hashq, hashv, hashx.
3298 * tags.h: made wvect an option bit of vector.

3308 initialization to fix a race condition.
3310 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
3311 object, not in a global.
3312 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)

3331 Thu Feb 15 11:39:09 1996 Tom Lord <lord@beehive>
3333 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
3334 set the multi_byte flag correctly in symbols. This is wrong.
3335 intern_obbary_soft and msymbolize should take an extra parameter.
3336 Also, weird multibyte symbols don't print correctly.
3337 The weird symbol syntax is also a bit bogus (emacs doesn't quite
3340 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
3342 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
3343 use the system symhash. == #t means create an uninterned symbol.
3345 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
3347 * strings.c (scm_make_shared_substring): build'em.
3348 It might better to keep a table of these and use one
3349 less cons-pair per shared-substring.

3419 * lvectors.c (scm_get_lvector_hook):
3420 In guile-ii, the lvector code was broken. It was fixed in guile-iii.
3421 It seems to me like if it is broken again in guile-iv...Here is a patch.
3422 "! || (LENGTH (keyvec) == 0))"
3423 (From: Mikael Djurfeldt <mdj@nada.kth.se>)
3426 * gscm.c (gscm_sys_default_verbosity):
3427 incorrectly declared for non-__STDC__
3428 (Tom_Mckay@avanticorp.com)
3430 * ports.c (scm_setfileno): Tweak the macro a bit
3431 to make it easier to port to systems that use
3432 more than a single structure field to hold a descriptor.
3434 * debug.c (change_mode): Avoid GNUCism "int foo[n];"
3435 Give a warning, not an error, for unrecognized modes.
3437 * eval.c (SCM_CEVAL):
3438 static char scm_s_for_each[];
