1 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3 * posix.c (scm_putenv): don't check HAVE_PUTENV.
4 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
6 * putenv.c: new file, from sh-utils 1.12.
8 * posix.c (scm_environ): use malloc in place of scm_must_malloc
9 since allocation isn't for Scheme objects.
10 (scm_putenv): copy strings before placing in the environment.
12 * stime.c (scm_current_time): throw an error if time returns -1,
13 instead of returning #f.
14 (scm_get_internal_real_time, scm_get_internal_real_time): use
15 scm_long2num for return value instead of SCM_MAKINUM.
17 * stime.h: prototypes updated.
19 * stime.c (scm_time_in_msec): apparently unused, deleted.
21 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
23 * configure.in: check for gettimeofday.
25 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
26 which may be more usefully portable than a gettimeofday interface.
28 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
30 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
32 * Makefile.in: Regenerated.
34 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
36 * stime.c (filltime): recovered static procedure.
37 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
40 * posix.h: add prototype for scm_close_pipe, remove prototypes for
41 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
43 * * posix.c (scm_mknod): split the mode argument into type and perms
44 arguments, like the extra fields returned by stat.
46 * fports.c (scm_pipob): set the close, free and print procedures.
47 (scm_close_pipe): new procedure.
49 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
50 define them in boot-9.scm
52 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
54 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
55 wan't defined. Don't include fd.h.
57 * Previously fd.h was regenerated whenever configure was run,
58 forcing a couple of files to be recompiled.
60 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
61 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
62 Check for _fileno as well as _file.
64 * ioext.c: don't fd.h.
65 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
68 * Change the stratigy for getting information about errno
69 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
70 generating lists of symbols during the build process, which will
71 not always work, include comprehensive lists in the distribution.
72 To help keep the lists up to date, the "check_signals" and
73 "check_errnos" make targets can be used.
75 * configure.in: don't check for a command to extract errno codes.
76 * Makefile.am: update file lists, remove errnos.list and errnos.c
77 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
79 (CLEANFILES): remove errnos.c and errnos.list, add
80 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
81 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
82 * errnos.default: deleted.
83 * cpp_signal.c: new file.
84 * cpp_errno.c: renamed from errnos_get.c.
85 * cpp_err_symbols, cpp_sig_symbols: new files.
86 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
87 * error.c (scm_init_error): #include cpp_err_symbols instead of
89 * posix.c (scm_init_posix): don't intern signal symbols. #include
92 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
94 * strop.c (scm_i_index): allow the lower bound to be equal to the
95 length of the string, so a null string doesn't always give an error.
97 * posix.h: new prototypes.
98 * posix.c (scm_status_exit_val, scm_status_term_sig,
99 scm_status_stop_sig): new functions, as in scsh. They break down
100 process status values as returned by waitpid.
102 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
104 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
105 configure doesn't know about it.
107 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
109 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
111 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
112 which defines C variables with global linkage.
114 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
116 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
119 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
121 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
122 has time to check why this doesn't work well with continuations.
124 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
126 * Fix shell syntax error; some shells won't tolerate
127 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
129 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
131 * posix.c (scm_uname): throw an error if uname fails instead
134 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
136 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
139 * async.c (scm_ints_disabled): definition moved from error.c.
141 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
143 * acconfig.h: Removed PACKAGE.
145 * scmconfig.h.in: Regenerated.
147 * snarf.h: g++ says it's non-portable not to specify the first
148 argument in a varargs declaration. I introduced the first
149 argument by using preprocessor conditionals.
151 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
153 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
154 (scm_freopen): use RO string macros for filename and modes.
155 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
157 * posix.c (scm_getgrgid): simplify conversion of name to C string.
158 (scm_mknod): use RO string macros for path.
160 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
161 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
163 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
164 use SCM_ROSTRINGP and SCM_ROCHARS.
166 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
168 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
171 * ramap.c (scm_ra_matchp, scm_ra_matchp, scm_array_fill_int, racp,
172 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
173 support for byte vectors.
175 * print.c (scm_iprin1): Limit number of vector elements printed
176 according to pstate->length.
178 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
180 * backtrace.c (scm_display_error_message): don't segv if message
183 * error.h: prototype for scm_error_scm.
185 * error.c (scm_error_scm): new procedure, reimplements scm-error
186 in C and uses scm_error.
188 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
190 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
191 pointer to the Scheme variable read-hash-procedures and intern it
192 in scm_init_read. Modify scm_read_hash_extend and
193 scm_get_hash_procedure to use the pointer.
195 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
197 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
198 (SCM_KEYWORD_STYLE): defined.
200 * read.c (scm_read_opts): add a keywords option. This isn't a
201 boolean option, in case someone wants to add support for DSSSL
203 Setup scm_keyword_prefix symbol.
204 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
206 * I've left keyword support disabled by default, since it doesn't
207 seem to break the module system and it gives R4RS standard behaviour.
208 It can be reactivated with (read-set! keywords 'prefix).
210 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
212 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
213 before constructing arbiter.
215 * eval.c (scm_m_define): Bugfix: Check that the object is a
216 closure before setting the procedure property!
218 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
220 * ports.c: Removed `ungetc-char-ready?'.
222 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
224 * read.c (scm_init_read): intitialise scm_read_hash_procedures
225 (idea from Mikael: make it a pair so scm_permanent object only
227 (scm_read_hash_extend): don't call scm_permanent_object.
228 (ideas from Mikael): if chr is already in the list, replace its
229 procedure instead of appending it again. If proc is #f, remove
231 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
233 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
235 * gdbint.c (gdb_read): update scm_lreadr usage.
237 * load.h: update prototypes.
239 * load.c (scm_primitive_load, scm_read_and_eval_x,
240 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
242 * read.h: add prototype for scm_read_hash_extend. Change args for
245 * read.c (scm_read_hash_procedures): new variable.
246 (scm_read_hash_extend): new procedure.
247 (scm_get_hash_procedure): new procedure.
248 * (scm_lreadr): use scm_get_hash_procedure instead of an argument
249 for extended # processing.
250 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
251 scm_read_token): remove case_i, sharp arguments. Change callers.
253 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
255 * read.h (SCM_N_READ_OPTIONS): increase to 3.
256 (SCM_CASE_INSENSITIVE_P): define.
258 * read.c: add case-insensitive option to scm_read_opts.
259 * (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
260 to determine whether to convert symbol case.
261 (default_case_i): definition removed.
262 * read.c (scm_read_token): if case_i, downcase ic before doing
265 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
267 * configure.in: Added configuration option `guile-debug'.
268 Configure with --enable-guile-debug if you want a bunch of extra
269 functions used for debugging when developing Guile.
271 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
273 * procs.c (make-cclo): New undocumented debugging procedure: Make
274 compiled closure with internal procedure PROC and length LENGTH.
275 Only compiled if GUILE_DEBUG is defined.
277 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
279 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
281 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
283 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
284 with 3 or more args internally to the evaluator.
286 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
288 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
289 with 3 or more args internally to the evaluator. This is mainly
290 because we don't want to pass entry and exit points of the
291 debug support twice, but it also seems to increase the speed of
292 the evaluator for such calls (e. g. (+ 1 2 3)).
294 * * backtrace.c (scm_display_application): New procedure:
295 display-application; Set fancy printing parameters individually
296 for different types of display (backtrace, error, application).
297 (These should of course be customizable!)
299 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
300 clear the CHECK-flags.
302 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
304 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
306 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
308 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
309 from pairs with a GLOC in the car.
311 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
312 otherwise `symbol-hash' will behave badly.
313 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
314 we get segmentation fault!
316 * * symbols.c: Added #include "weaks.h". New functions:
317 `builtin-bindings' and `builtin-weak-bindings'. (These will be
318 moved to an extraneous library when we split libguile.)
320 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
322 * filesys.c (scm_stat): stat now takes fport arguments too as
323 documented in the manual.
325 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
327 * debug.c (scm_single_step): Bugfix: Call continuation with
328 scm_call_continuation instead of throwing to it.
330 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
332 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
333 argument wasn't declared to be optional.
335 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
337 * stime.c (scm_init_stime): Add feature "current-time".
339 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
341 * throw.h: prototype for scm_exit_status.
342 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
343 args to derive an exit status. Allows (quit) to work from a
345 (scm_exit_status): new function.
348 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
350 * eval.c (scm_deval): Removed some old code.
351 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
353 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
356 * symbols.c (msymbolize): Bugfix: Must initialize property list to
359 * procs.c: Introduce the existent C function scm_thunk_p at the
360 Scheme level as well.
362 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
364 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
365 used from C to easily lookup the value of a symbol in the current
368 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
370 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
371 scm_init_unif in this file. This will also fix a previous problem
374 * configure.in: Added AM_MAINTAINER_MODE
376 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
378 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
381 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
383 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
384 source files that are not always included in libguile but should
385 have their dependencies calculated by automake. This variable is
386 recognized by automake, no further magic is needed.
387 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
388 to deal exclusively with *.lo files, as it seems. The *.o files
389 are built automatically when the corresponding *.lo file gets
392 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
394 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
397 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
399 * unif.c (scm_array_set_x): minor change to argument error checking.
401 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
403 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
404 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
405 They should only be included in the library at configure.in's
407 (libguile_la_LDADD): Include the appropriate .lo files here.
408 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
409 so we know when to build them (and their .lo bretheren).
410 * configure.in (LIBLOBJS): New substituted variable. We let
411 configure decide which .o files to include in LIBOBJS, and then
412 put the corresponding list of .lo files in LIBLOBJS. The latter
413 is what we pass to libtool.
414 * Makefile.in, configure: regenerated.
416 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
418 * symbols.c (scm_sysintern0): New function. Contains the core of
419 old scm_sysintern but doesn't take a second value argument.
420 (scm_sysintern): Now uses scm_sysintern0.
421 (scm_sysintern_no_module_lookup): Renamed to
422 scm_sysintern0_no_module_lookup and doesn't take a second value
425 * symbols.h (scm_sysintern0: Added declaration.
427 * options.c (scm_init_opts): Use scm_sysintern0 instead of
428 scm_sysintern when interning option keys. Otherwise we risk
429 destroying the values of already interned variables.
431 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
432 scheme-level boolean (use SCM_NFALSEP).
434 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
436 (scm_backtrace): New function. (C version of old function from
437 boot-9.scm) Motivation: Make it possible to display backtraces
438 without depending on boot-9.scm. (I'm uncertain if this
439 motivation is good enough...)
441 * root.h (scm_root_state): Add member the_last_stack_var.
442 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
444 * root.c (mark_root): Mark scm_the_last_stack_var.
446 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
449 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
451 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
452 1. mark_lazy_catch didn't mark the smob.
453 2. Both functions above have standard variants:
454 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
455 free_lazy_catch --> scm_free0.
457 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
459 * throw.c (scm_internal_lazy_catch): New function.
460 (scm_lazy_catch): Rewritten to use it.
461 (scm_ithrow): Handle the new lazy catch representation.
462 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
463 that doesn't have a jmpbuf is a lazy catch clause.
464 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
465 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
466 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
468 (scm_init_throw): Register the new lazy-catch smob type.
469 * throw.h (scm_internal_lazy_catch): decl for new function.
471 * throw.c (scm_internal_catch): Doc fixes.
473 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
474 configure.in. Including this might cause problems if applications
475 that link against libguile include their own copies of alloca, but
476 if they're using autoconf, they should be adding libguile to LIBS
477 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
478 the copy in libguile, and things will be okay. (I think.)
480 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
482 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
484 strop.h: move prototypes too.
486 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
488 * posix.c (scm_init_posix): don't intern EINTR since it's now done
491 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
492 etc. I deleted them from filesys.c long ago, but didn't
493 notice they were here too (although ineffective since
494 sys/stat.h wasn't included).
496 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
498 * eval.c: Don't define alloca in GCC case. gcc will automatically
499 use __builtin_alloca if appropriate.
501 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
503 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
504 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
505 that values of automatic variables are preserved. See comments
506 for safe_setjmp for details.
508 Change from Thomas Morgan:
509 * variable.c: Include eq.h.
510 (var_equal): New function.
511 (variable_smob): Use var_equal as the discriminator for variables.
513 * throw.c (s_throw): Remove extraneous declaration.
515 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
516 * eval.c: Add necessary CPP cruft to support that.
517 * configure, Makefile.in, scmconfig.h.in: regenerated.
519 Change from Thomas Morgan:
520 * procprop.c (scm_procedure_properties): Convert the Scheme
521 boolean returned by scm_procedure_p into a C boolean before using
522 it as a condition for SCM_ASSERT.
523 (scm_procedure_property): Likewise.
525 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
526 indications of Unixness.
529 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
531 * * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
533 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
535 * read.c (scm_lreadr): use scm_misc_error to improve one of the
536 "unknown # object" error messages.
538 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
539 (scm_i_index) and declare it static. Add a 'direction' argument
540 to indicate what way the search should go.
541 (scm_i_index): throw out-of-range error instead of wrong-type-arg
543 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
544 strop.h: remove scm_i_index, scm_i_rindex prototypes.
546 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
548 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
550 * * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
551 to avoid clash with various scsh forks.
553 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
555 The following two changes (ramap.c, throw.c) are motivated by the
556 apparent unportability of forward declarations of static arrays of
557 the form `static foo bar[];'.
559 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
560 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
562 * throw.c (scm_throw): Moved above scm_ithrow.
564 * options.h: Removed the extern declarations of scm_yes_sym and
565 scm_no_sym since these are static.
567 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
569 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
571 * Makefile.am: remove AWK=@AWK@.
572 Add a rule for generating errnos.list.
573 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
575 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
576 don't extract errnos, just set a variable (avoids the
577 need to recompile error.c just because configure is run.)
579 * unif.h: update prototypes.
580 * unif.c (scm_uniform_array_read,write): change the offset and
581 length arguments to start and end, for consistency.
583 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
585 * ioext.h: update prototypes.
586 * * ioext.c (scm_read_delimited_x): replaces scm_read_line and
587 scm_read_line_x, it's a more general procedure using an
588 interface from scsh. read-line and read-line! are now defined
590 * Note that the new read-line trims the terminator
591 by default, previously it was appended to the returned string. An
592 optional argument specifies how to process the terminator (scsh
593 compatible). For the old behaviour: (read-line port 'concat).
594 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
595 returns a pair, but is converted to multiple values if the scsh
598 socket.h: update prototypes.
599 * socket.c (scm_recvfrom): for consistency with other procedures,
600 take start and end as separate optional arguments.
601 * (scm_recv, scm_recvfrom): don't allow the second argument
602 to be a size, only a buffer. Change the scheme names to
603 recv! and recvfrom!. Don't return the buffer.
605 * ioext.h, posix.h: move prototypes too.
606 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
607 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
608 "read.h" and "unif.h".
609 * ioext.c: include "chars.h"
611 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
613 * dynl.c: The dynamic linking and module registration functions
614 are now defined even when dynamic linking is not available for the
615 host system. Some of their functionality can be done without
616 dynamic linking; when it's really needed, they throw errors.
618 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
620 * configure.in: Only define DYNAMIC_LINKING when one of the system
621 dependent functions is detected.
622 * dynl.c (scm_dynamic_func): New function to get the address of a
623 function in a dynamic object.
624 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
625 produced by scm_dynamic_func as the thing to call.
627 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
629 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
630 (scm_register_module_xxx, scm_registered_modules,
631 scm_clear_registered_modules): New functions.
633 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
635 * symbols.c (scm_sysintern): Renamed to
636 scm_sysintern_no_module_lookup.
637 (scm_sysintern): New function to take the place of the old
638 scm_sysintern. It uses the current toplevel lookup closure to give
639 the symbol its value. This is a temporary hack to put packages
640 like gtcltk into their own module.
641 (scm_can_use_top_level_lookup_closure_var): New variable to tell
642 us whether `scm_top_level_lookup_closure_var' has been initialized
644 * eval.c (scm_init_eval): Set it.
646 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
648 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
649 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
651 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
653 * (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
654 scm_sys_dup): deleted: FD capability will be added to other
656 * Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
657 scm_fd_free, fd_smob, scm_intern_fd.
658 * (scm_open): renamed from scm_sys_open. Return a port instead of
659 an FD object. Make the mode argument optional.
660 * (scm_sys_create): deleted, it's just a special case of open.
661 (scm_init_filesys): move interning of constants O_CREAT etc.,
662 here (were previously using SCM_CONST_LONG macro).
663 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
665 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
666 include "fports.h" and <stdio.h>
667 (scm_stat, scm_select): don't support FD objects.
669 * error.h: adjust scm_syserror_msg prototype.
670 * error.c (scm_syserror_msg): take an extra argument for errno.
671 Using the global value didn't always work, since it could be
672 reset by procedure calls in the message or args arguments.
674 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
675 I don't understand why the check was there (and what about the
678 * strop.c (scm_string_copy): allow shared substrings to be copied.
680 * unif.h: corresponding change to prototypes.
681 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
682 recognize two new optional arguments: offset and length. Allow
683 the port argument to be an integer (file descriptor, for scsh).
684 Include <unistd.h> for "read" prototype.
686 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
688 * socket.c: don't include filesys.h.
690 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
692 * Makefile.am: add AWK=@AWK@ (?)
694 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
696 Add a rule to generate errnos.c from errnos.
697 * error.c (scm_init_error): include errnos.c.
698 * errnos_cnvt.awk: new file, converts the list of errno codes to
700 * errnos_get.c: new file.
701 * errnos.default: new file, contains errnos to try if they can't
702 be extracted from errno.h.
703 * configure.in: if using GCC, try and extract errno codes from
707 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
709 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
710 * Makefile.am: Made libguile into a libtool library.
711 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
712 Set libtool_libs to indicate that libguile is a libtool library.
713 See guile/ChangeLog for details.
714 * .cvsignore: ignore "*.lo", the libtool library objects.
716 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
718 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
719 use htons in getservbyport argument.
721 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
723 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
724 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
727 * objprop.c (scm_object_property): No need to take the CDR of the
728 value returned by scm_object_properties, since Aug 20 change.
730 * configure.in: When checking for struct linger, #include
731 <sys/types.h> as well as <sys/socket.h>. I've never known
732 <sys/types.h> to cause any portability problems, and Solaris's
733 <sys/socket.h> needs it.
734 * configure: Rebuilt.
736 I think the Sun compiler has chosen a perverse way to interpret
737 ANSI declarations combined with K&R definitions. We'll
738 appease it a little bit. But when it invades France, we fight.
739 * print.c (scm_iprlist): Change 'tlr' argument to an int.
740 * print.h (scm_iprlist): Here too.
741 * numbers.c (scm_divbigdig): Change definition to match
742 declaration in numbers.h.
743 * unif.c (scm_makflo): Change definition to match declaration in
746 * init.c (scm_boot_guile): Don't return the value of
747 scm_boot_guile_1. This function doesn't return a value;
748 scm_boot_guile_1 doesn't return a value (or return at all).
750 * eval.c (unmemocopy): Add a semicolon to appease the Sun
753 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
754 compile. I have a feeling this function is a bad idea anyway ---
755 one should always test for features, not systems.
757 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
758 semicolons. Only pure luck kept this from being noticed earlier.
760 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
762 * socket.c (scm_recvfrom): Added missing semicolon.
764 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
766 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
767 the buffer and start and end positions for scsh networking
770 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
772 * configure.in: Revert previous change to this file; the problem
773 is due to transient automake weirdness.
774 * configure: Rebuilt.
776 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
777 PLUGIN/guile.libs. configure generates the latter from the former.
778 * Makefile.in: Rebuilt.
780 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
781 need this if we install scripts, like guile-snarf.
782 * configure: Rebuilt.
784 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
786 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
788 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
790 * socket.c (scm_addr_vector): fix faulty scm_listify.
792 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
794 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
795 style block comment is no longer considered an error.
797 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
799 * PLUGIN/guile.libs.in: New file.
800 * PLUGIN/guile.libs: Removed from repository.
801 * configure.in: Create PLUGIN/guile.libs from
802 PLUGIN/guile.libs.in. This is for including additonal libraries
803 needed for dynamic linking.
804 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
805 instead of PLUGIN/guile.libs.
807 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
809 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
811 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
812 occurrences of the given element from the list, not just the
813 first. This is how the Emacs Lisp functions behave, how the
814 analogous Common Lisp functions behave, and (I believe) how the
815 older Maclisp functions worked. I realize that this change may
816 break code, but it seemed better to break it before the Guile
819 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
820 Their prototypes were already present in gc.h, but they weren't
822 (scm_init_storage): Initialize scm_protects.
823 * root.c (scm_protects): New element of scm_sys_protects.
825 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
827 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
829 * libguile.h: Added #include "libguile/net_db.h".
831 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
832 30 change. That file is only meant for communication between the
833 configuration process and load.c. If code linked against libguile
834 wants to get at the paths mentioned in libpath.h, it can call
835 functions declared in load.h.
837 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
839 * libguile.h: Removed #include "libguile/fdsocket.h"
841 * net_db.c: Added #include <sys/socket.h>.
843 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
845 * filesys.c (scm_input_waiting_p): use select in preference to
846 FIONREAD, since the latter doesn't detect EOF.
847 Throw error if neither select nor FIONREAD available.
849 * socket.c (scm_connect): take a port, not a fd object.
850 (scm_fill_sockaddr): throw an error if fam is not recognised.
851 (scm_bind): use scm_fill_sockaddr.
852 (scm_listen): take a port, not a fd object.
853 (scm_accept): take and return a port. return #f in the car if
855 (scm_sock_fd_to_port): new procedure.
856 (scm_socket): use scm_sock_fd_to_port.
857 (scm_addr_vector): throw error if unrecognised address type.
858 take an extra argument with the calling procedure name.
859 (scm_getsockname): take a port. return #f if address can't be got.
860 (scm_getpeername): take a port. return #f if address can't be got.
861 (scm_recvfrom): take a port. return #f for address component if can't
863 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
864 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
866 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
868 * throw.c (scm_internal_catch): Make body funcs and handler funcs
869 use separate data pointers, to allow them to be designed
870 independently and reused.
871 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
872 Renamed from catch_body, catch_handler, and uncaught_throw; made
874 (struct scm_catch_body_data): Renamed from catch_body_data; moved
876 (scm_catch): Use the above.
877 (scm_throw): Don't bother printing a message for an uncaught
878 throw; we establish a default handler in init.
879 * throw.h (scm_internal_catch): Prototype updated.
880 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
882 (struct scm_body_thunk_data): New structure, used as data
883 argument to scm_body_thunk.
884 * init.c (struct main_func_closure): New structure, packaging up
885 the data to pass to the user's main function.
886 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
887 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
888 scm_internal_catch to establish a catch-all handler, using
889 scm_handle_by_message. This replaces the special-case code in
891 (invoke_main_func): Body function for scm_internal_catch; invoke
892 the user's main function, using the main_func_closure pointer to
893 decide what to pass it.
894 * root.c (struct cwdr_body_data): Remove handler_proc member.
895 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
896 (cwdr_handler): Removed.
898 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
900 * socket.h (SCM_P): update bind prototype.
901 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
903 (scm_socket): return a port, not a file descriptor object.
904 include "fports.h" and <unistd.h>
905 (scm_bind): take a port, not a file descriptor object.
906 take an extra argument for address args.
908 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
909 INADDR_NONE, INADDR_LOOPBACK.
911 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
913 * init.c: include net_db.h and not fdsocket.h.
914 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
916 * Makefile.am: corresponding changes.
917 * socket.h: renamed from fdsocket.h, fix names.
918 * net_db.h: renamed from socket.h, fix names.
919 * socket.c: renamed from fdsocket.c.
920 remove _sys from procedure names.
921 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
922 add "socket" to features list.
923 * net_db.c: renamed from socket.c.
924 remove _sys from procedure names.
925 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
926 add "net-db" to features list.
927 include "net_db.h". don't include <sys/socket.h> or
930 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
932 * tags.h (scm_tags): Removed comma at end of last enumerator.
934 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
936 Don't use GCC extensions to allocate space for debugging frames.
937 (Here he goes again! Why do we put up with this?!)
938 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
939 an scm_debug_info structure, not an in-line array of them. Add
940 'info' member, to say how many vect elements we've used, for eval
942 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
943 a new variable debug_info_end to mark the end of vect, instead of
944 the address of the 'info' pointer itself.
945 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
946 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
947 (SCM_APPLY): Explicitly allocate space for debug.vect.
948 * debug.c (scm_m_start_stack): Same, for vframe.vect.
949 * stacks.c: Adjusted for new debug frame structure.
950 (RELOC_INFO, RELOC_FRAME): New macros.
951 (stack_depth, read_frames): Use them, and new scm_debug_frame
952 element 'info', instead of magically knowing that eval frames have
953 an info pointer sitting after vect.
954 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
956 (scm_init_stacks): Formatting tweaks.
958 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
960 Give GCC more control flow information, so it can be sure that
961 variables aren't used uninitialized.
962 * error.h (scm_error, scm_syserror, scm_syserror_msg,
963 scm_sysmissing, scm_num_overflow, scm_out_of_range,
964 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
965 scm_misc_error): Tell GCC that these functions never return.
966 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
967 out the field type, call abort if SCM_ASSERT returns, to placate
969 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
970 scm_wta ever returns. We can't handle this case anyway, and this
971 gives the optimizer more information.
972 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
973 scm_wta ever returns.
975 In some cases, the code is fine, but GCC isn't smart enough to
976 figure that out; this usually happens when one variable is only
977 initialized and used when a particular condition holds true, and
978 we know that condition will never change within a given invocation
979 of the function. In this case, we simply initialize the variables
980 to placate the compiler, hopefully to a value which will cause a
981 crash if it is ever actually used.
982 * print.c (scm_iprin1): Initialize mw_pos.
983 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
984 * throw.c (scm_ithrow): Initialize dynpair.
985 * unif.c (scm_uniform_vector_ref): Initialize cra.
986 * struct.c (init_struct): Initialize prot.
987 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
989 * strports.c (scm_eval_0str): Don't return uninitialized garbage
990 if EXPR contains no expressions.
992 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
994 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
995 cause an infinite loop (???). So much for the algebraic
996 equivalency of variable-sized arrays and alloca...
998 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
1000 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
1001 a SCM boolean, not a C boolean.
1003 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
1005 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
1006 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
1007 rules for raising scm_mtrigger. Previously, unfortunate but not
1008 unlikely circumstances could result in almost constant invokation
1009 of the gc. Now, this situations should be less likely, but they
1010 are not prevented completely.
1012 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
1014 * numbers.c (scm_fuck): Procedure removed; looks like old test
1016 * numbers.h: Prototype removed.
1018 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
1020 * debug.h (scm_debug_frame): Change `vect' member from an in-line
1021 array to a pointer, to match my Nov 21 change in eval.c.
1023 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1025 * libguile.h: Added #include "libguile/backtrace.h", #include
1026 "libguile/stacks.h".
1028 * strings.c (scm_string scm_make_string scm_string_ref
1029 scm_string_set_x scm_string_equal_p scm_string_append):
1030 Bugfix according to scm patch from Aubrey Jaffer:
1031 Corrected long-standing
1032 (not (eqv? (integer->char 128)
1033 (string-ref (make-string 1 (integer->char 128)) 0)))
1034 bug found by John Kozak <jk@noontide.demon.co.uk>.
1036 * strports.c, strports.h: Make scm_eval_0str return the value of
1037 the last expression evaluated (previously, it returned void).
1039 * strports.c, strports.h: New function: scm_read_0str. Does what
1042 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1044 * simpos.c (scm_getenv): return #f if string can't be found in the
1045 environment instead of throwing an exception, for compatibility
1046 with numerous other systems.
1048 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
1050 * Makefile.am (.c.x): Use guile-snarf.
1051 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
1053 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
1055 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1057 * backtrace.c (scm_display_error_message): Made non-static, and
1058 renamed from display_error_message.
1059 * backtrace.h (scm_display_error_message): Added extern decl.
1060 * throw.c (uncaught_throw): Use it to display the error message.
1062 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
1064 * inet_aton.c: Use #if 0, not #ifdef 0.
1066 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
1068 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
1069 to convert the returned value.
1070 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
1071 the offset argument.
1073 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1075 Add new interface to catch/throw, usable from C as well as
1077 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
1078 (scm_internal_catch): New function, replaces...
1079 (scm_catch_apply): Deleted.
1080 * throw.c (scm_catch_apply): Deleted; replaced with a more general
1081 mechanism which is a bit more code, but can be used nicely from C
1082 and implement the Scheme semantics as well.
1083 (scm_internal_catch): This is the replacement; it's named after
1084 the analogous function in Emacs.
1085 (scm_catch): Reimplemented in terms of the above.
1086 (struct catch_body_data, catch_body, catch_handler): New
1087 functions, used by scm_catch.
1088 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
1089 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
1090 support for new cwdr.
1092 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
1095 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
1097 * acconfig.h: Added DYNAMIC_LINKING symbol.
1098 * configure.in: Add option and checks for dynamic linking.
1099 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
1100 dynl.h: New files for dynamic linking support.
1101 * Makefile.am (libguile_a_SOURCES):
1103 (modinclude_HEADERS): Added "dynl.h".
1104 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
1106 * init.c (scm_boot_guile_1): Call
1107 scm_init_dynamic_linking to initialize dynamic linking support.
1109 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
1111 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
1112 (as we Schemers say). It needs to be global, so that I can tweak
1113 it for the proper operation of unexec.
1114 (scm_boot_guile_1_live): New variable, see above.
1116 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
1118 * guile-snarf.sh: Removed.
1119 * PLUGIN/guile.libs: Added dependency for -lm.
1120 * acinclude.m4: Renamed from aclocal.m4.
1121 * PLUGIN/greet: Removed.
1122 * Makefile.am, aclocal.m4: New files.
1123 * configure.in: Updated for Automake.
1125 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
1127 * eval.c (scm_definedp): Use top_level_lookup_closure_var
1128 and not top_level_lookup_thunk_var.
1130 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
1132 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
1134 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
1136 * eval.c (scm_definedp): Incompatibly changed to be a builtin
1137 Scheme function, instead of syntax. Single argument is now a
1140 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1142 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
1143 scm_ra_divide): Properly terminate statements passed as arguments
1144 to IVDEP macros. (Thanks to Bernard Urban.)
1146 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
1147 with non-constant sizes. (Thanks to Bernard Urban.)
1149 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1151 It's an "eval closure", not an "eval thunk." A thunk is a
1152 function of no arguments.
1153 * root.h (struct scm_root_state): Renamed
1154 top_level_lookup_closure_var from top_level_lookup_thunk_var.
1155 (scm_top_level_lookup_closure_var): Renamed from
1156 scm_top_level_lookup_thunk_var.
1157 * root.c (mark_root): Uses changed.
1158 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
1159 * init.c (scm_start_stack): Uses changed.
1160 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
1161 Change scheme-visible name to *top-level-lookup-closure* from
1162 *top-level-lookup-thunk*.
1164 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
1166 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
1167 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
1169 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
1171 * gc.c (struct scm_heap_seg_data): Doc fixes.
1173 * gc.c (scm_gc_sweep): Empty all segments' freelists before
1174 sweeping. Then, prepend each segment's free cells to its
1175 freelist, rather than wiping out the old value. (Thanks to Marius
1178 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
1179 scm_check_freelist, scm_debug_newcell): New functions and
1180 variables, for debugging freelist problems.
1181 * pairs.h (SCM_NEWCELL): New debugging version added.
1182 * gc.h (scm_debug_newcell): Added extern declaration, used by
1183 debugging version of SCM_NEWCELL.
1185 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1187 On some systems <libc.h> conflicts with <unistd.h>, and should not
1188 be #included at all.
1189 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
1190 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
1191 * configure.in: Call it.
1192 * posix.c, filesys.c: Use its results to decide whether or not to
1194 * configure, scmconfig.h.in: Rebuilt with autoconf and
1197 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1199 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
1200 pointer to the stdio stream before calling scm_setbuf0, so the
1201 latter will be able to retrieve it. I'm surprised this didn't
1202 segfault earlier. (Thanks to Christopher Lee.)
1204 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1206 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
1209 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1211 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
1212 number of stack narrowing specifier pairs. The first specifier in
1213 a pair controls inner border, the second the outer border. A
1214 number means cut that number of frames, a procedure object means
1215 cut until that object is found in operator position in a frame.
1217 * root.c (cwdr): Bugfix.
1219 * read.c: Recording of positions disabled by default.
1221 * procs.c (scm_closure_p): New function.
1223 * posix.c (scm_tmpnam): New function.
1225 * load.c: Added #include "throw.h".
1226 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
1229 * load.c, load.h (scm_read_and_eval_x): New function.
1231 * eval.c: Renamed debug option "deval" to "debug".
1233 (scm_eval_x): `eval!' is no longer accessible from the scheme
1234 level. Motivation: We can't allow operations which introduce
1235 glocs into the scheme level. Guile's type system can't handle
1236 these as data. Use `eval' or `read-and-eval!' as replacement.
1238 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
1239 SCM_CONSP since this is a macro!; Set vframe.prev to
1240 scm_last_debug_frame instead of 0. In this way we can look
1241 "above" the virtual start stack frame if we wish.
1242 (scm_debug_hang): New function: Useful for debugging Guile in
1243 certain tricky situations. Will probably be removed later...
1245 * debug.h: Changed semantics of debug option "backtrace". This
1246 option now only indicates whether we want automatic backtrace at
1249 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1251 * ports.c: #include "filesys.h"
1252 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
1254 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
1255 Motivation: This is system specific code which is related to file
1256 I/O. It also may use select. Added code by Gary Houston to
1257 detect presence of character in stdio buffers.
1259 * libguile.h: #include "libguile/libpath.h"
1261 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
1262 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
1263 SCM_SITE_DIR; Install libpath.h among the other include files.
1265 * load.c, load.h (scm_sys_package_data_dir): New function.
1267 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1269 * stacks.h: Bugfix: Don't use tail-array length field as stack
1270 length field! This screwed GC.
1272 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1274 * _scm.h: Added #ifndef around definition of macros min and max.
1276 * __scm.h: Added hooks for threads to plugin to in ints protection
1277 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
1278 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
1279 the main code in these macros duplicated and spread over multiple
1280 files. Renamed SCM_THREADS_SWITCHING_CODE ->
1281 SCM_THREAD_SWITCHING_CODE.
1283 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
1285 * snarf.h: New file.
1286 * guile-snarf.sh: New file.
1287 * Makefile.in (inner_h_files): Added snarf.h
1288 (ancillary, install, uninstall, distclean): Added actions for
1290 (.c.x): Use guile-snarf.
1291 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
1292 (gen_c_files): Note that these depend on guile-snarf.
1293 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
1294 now in "snarf.h". Added #include "snarf.h" to get them.
1295 * libguile.h: Added #include "snarf.h".
1296 (Patches applied and tweaked by Jim Blandy.)
1298 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1300 * socket.c: Use K&R style declaration for 'close'; the GNU coding
1301 standards suggest against providing prototypes for system
1302 functions. Thanks to Greg Troxel.
1304 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1306 * strports.c (scm_eval_0str): New function.
1307 #include "read.h", to get prototype for scm_read.
1308 * Makefile.in (strports.o): Update dependencies.
1309 * strports.h: New prototype.
1311 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
1312 scheme name from "int?" to "integer?". It seems to do the job.
1313 * numbers.h: Rename prototype too.
1314 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
1317 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
1318 scm_num_eq_p): Rename these according to R4RS conventions: call
1319 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
1320 to making libguile R4RS compliant without ice-9...
1322 * load.c (scm_sys_search_load_path): Search for files under all
1323 extensions listed in the %load-extensions variable. If FILENAME
1324 is absolute, return it unchanged, without searching the load path.
1325 (scm_loc_load_extensions): New variable, pointing to
1326 %load-extensions' value cell.
1327 (scm_init_load): Initialize it, and the value it points to.
1328 (scm_primitive_load_path): Improve error reporting.
1330 * load.c (scm_loc_load_hook): New variable, pointing to value cell
1331 of new Scheme variable %load-hook.
1332 (scm_primitive_load): Apply %load-hook to filename.
1334 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
1336 * configure.in: add tests for figuring out whether buffered data
1337 is available in a FILE structure, which is needed by char-ready.
1339 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
1342 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
1343 exceptions using misc_error instead of syserror. It seems a bit
1344 odd to throw an exception if a string can't be found in the
1345 environment, but it's consistent with open-file, stat etc.
1346 (simpos.h): remove sys_ from getenv.
1348 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
1349 occurs, throw an error instead of returning errno. Return value
1351 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1353 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1355 * filesys.c (scm_stat2scm): derive file type and permissions from
1356 the stat mode and append them to the returned vector.
1357 There isn't much overhead in doing this and it avoids the need to
1358 work with S_IRUSR et al. in Scheme.
1359 Define symbols scm_sym_regular etc.
1360 (scm_init_filesys): don't intern S_IRUSR etc.
1362 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1363 and s_primitive_load_path.
1365 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1367 * error.h: don't declare error symbols. prototype for scm_misc_error.
1369 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1372 * error.c: use SCM_SYMBOL to set up error keys.
1373 scm_misc_error: new procedure.
1375 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1377 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1378 between `#!' and `!#' is ignored.
1379 (skip_scsh_block_comment): New function.
1381 * feature.c (scm_set_program_arguments): New argument, FIRST.
1382 * feature.h: Update prototype.
1383 * init.c (scm_boot_guile_1): Pass new argument to
1384 scm_set_program_arguments.
1386 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1388 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1389 (scm_boot_guile): Call scm_set_program_arguments here, later than
1390 the old initialization.
1392 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1393 initialization procedure.
1394 - Delete in, out, err arguments; there are other perfectly good
1395 ways to override these when desired.
1396 - Delete result argument; this function shouldn't ever return.
1397 - Rename init_func argument to main_func, for less confusion.
1398 - Delete boot_cmd argument; main_func is more general.
1399 -Add 'closure' argument, to help people pass data to main_func
1400 without resorting to global variables.
1401 - Abort if reentered; don't bother returning an error code.
1402 - Call scm_init_standard_ports to set up the default/current
1403 standard ports; no need to pass them to scm_start_stack.
1404 - Remove code to evaluate the boot_cmd, and start the repl; let
1405 the user do something like that in main_func if they want.
1406 - Remove code to package up a return value; main_func can do any
1408 - Call exit (0), instead of returning.
1409 (scm_start_stack): Don't initialize the I/O ports here; that's
1410 weird. Delete in, out, err arguments. Move guts to
1411 scm_init_standard_ports, scm_stdio_to_port.
1412 (scm_init_standard_ports): New function, to set up current and
1413 default standard ports.
1414 (scm_start_stack, scm_restart_stack): Make these static.
1415 * init.h (scm_boot_guile): Adjust declaration.
1416 (scm_start_stack, scm_restart_stack): Remove externally
1417 visible declarations for these.
1418 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1420 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1421 written out several times in scm_start_stack.
1422 * fports.h: New declaration for the above.
1424 * feature.c (scm_set_program_arguments): New function.
1425 * feature.h: New declaration for the above.
1427 * ports.c: Formatting tweak.
1429 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1431 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1432 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1433 for obtaining the address of a car or cdr field. Motivation:
1434 &SCM_CXR make assumptions about the internal structure of the
1437 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1438 Motivation: see SCM_CXRLOC.
1440 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1441 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1442 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1443 Motivation: Safer use. Some other macros are defined in terms of
1444 these operations. If these are defined using the SCM_SETCXR
1445 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1446 to inefficiency and an <e1> with side-effects could potentially
1447 break. Also, these particular operations are heavily utilized in
1448 the garbage collector. In unoptimized code there will be a
1451 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1452 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
1453 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
1454 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
1455 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
1456 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1457 vports.c: Cleaned up use of pairs: Don't make any special
1458 assumptions about the internal structure of selectors and
1459 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1460 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1461 (Among other things, this change makes it easier to build Guile
1462 with certain compilers which have problems with casted lvalues.)
1464 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1466 * stacks.c: Improve selection of relevant stack frames when making
1467 a stack object. Introduce one level of indirection in the stack
1468 object to make it possible to "narrow" to a certain region of the
1469 stack. This facilitates making use of more clever algorithms (not
1470 implemented) for selecting relevant frames and gives a cleaner
1471 design since selection of frames can be done independently of
1472 extraction of frames from the real stack.
1473 (scm_stack_id): Also take #t as argument which means look at
1476 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1477 Turn n_tail into an integer directly representing current number
1478 of frames in stack. Add field tail.
1480 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1482 * debug.c (scm_make_memoized): Made it available at scheme level.
1483 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1484 SCM_NIMP before applying heavier predicates in argument checking.
1485 (scm_local_eval): Also take memoized object as argument.
1487 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1488 aren't created with zero length, but should such a strange
1489 creature suddenly turn up...
1491 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1493 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1494 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1496 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1498 * variable.c (scm_make_variable): Make the name hint optional, as
1500 (anonymous_variable_sym): Renamed from variable_sym. All uses
1503 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1504 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1505 of scm_primitive_load_path was also changed to
1506 "primitive-load-path", from "%try-load-path". Callers changed.
1507 We'd like to respect the convention that a function named
1508 "try-mumble" should behave just like the function called "mumble",
1509 but return #f instead of signalling some error.
1510 * load.h: Rename prototypes.
1512 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1514 * print.c (make_print_state, grow_print_state), print.h: Modified
1515 the print state representation: Don't use a tail array for
1516 recording of circular references. Resizing of the print state
1517 structure invalidates the print state pointer. To avoid passing
1518 around an indirect print state reference to all printing
1519 functions, we instead let the print state reference a resizable
1522 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1524 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1525 Don't crash when passed an improper list terminated by a
1526 non-immediate value.
1528 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1530 Allocate data for structures on an eight-byte boundary, as
1531 required by the tagging system.
1532 * struct.c (alloc_struct): New function.
1533 (scm_make_struct, scm_make_vtable_vtable): Call it.
1534 * struct.h (scm_struct_n_extra_words): Bump to 3.
1535 (scm_struct_i_ptr): New "field".
1536 * gc.c (scm_gc_sweep): When we need to free the data, use the
1537 information stored by alloc_struct to find the beginning of the
1538 block allocated to the structure, so we can free it.
1540 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1542 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1545 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1546 (scm_debug_info): New member: id.
1548 * stacks.c: Stacks are now represented as structs; Stacks have an
1549 id given to them by `start-stack'.
1550 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1552 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1553 Changed stack representation.
1555 * debug.c (scm_procedure_name): Try procedure property `name' for
1556 compiled closures aswell.
1558 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
1560 * eval.c: scm_i_name moved to gsubr.c
1561 (scm_m_define): Record names of all kinds of procedure
1562 objects. (Earlier, only closures were recorded.)
1564 * procprop.h: Added declaration of scm_i_name.
1566 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1567 (scm_make_gsubr): Record names of compiled closures.
1569 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1571 * debug.c, debug.h: Removed obsolete code.
1573 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1574 stacks.c: Renamed regs --> scm_contregs.
1576 * print.c (scm_free_print_state): Cleanup print state before
1577 returning it to pool. It is better to do it here than in
1578 scm_prin1 since scm_prin1 is called often.
1580 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1581 s_set_source_property_x): Check that first argument is a pair or a
1584 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1585 scm_i_line, scm_i_column and scm_i_breakpoint global.
1587 * init.c: Added #include "backtrace.h" and #include "stacks.h".
1588 (scm_boot_guile_1): Added calls to scm_init_backtrace and
1591 * debug.h: Added debug object smob declaration and macro
1594 * configure.in: Build with backtrace.o and stacks.o if debug
1597 * Makefile.in: Added entries for new files: backtrace.c,
1598 backtrace.h, stacks.c and stacks.h.
1600 * symbols.c (scm_sym2ovcell): Fixed documentation.
1602 * _scm.h (min, max): Added.
1604 * async.c: Moved `min' macro to _scm.h.
1606 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1607 SCM_BACKTRACE_INDENT.
1609 * eval.c: Added new debug options `maxdepth' and `indent'.
1611 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
1613 * print.h: Added selector SCM_PRINT_STATE.
1615 * print.c: New functions: scm_make_print_state,
1616 scm_free_print_state.
1618 * print.h: Added declarations for scm_make_print_state,
1619 scm_free_print_state.
1621 * debug.c (scm_m_start_stack): New acro.
1623 * debug.h: Small cleanup.
1625 * init.c (scm_boot_guile_1): Moved scm_init_debug below
1628 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

1648 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
1649 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
1650 declare functions with prototypes. (Patch thanks to Marius
1653 More prototype-related changes from Marius Vollmer:
1654 * gdb_interface.h: Wrapped header file in #ifdef/#endif
1655 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
1656 * ports.h (ptobfuns): Added prototypes. This means some casting in
1658 * fports.c: Added casts for initializations, since the functions
1659 are defined to take FILE * as their stream argument, not SCM.
1660 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
1661 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
1662 to `char *str_data' to conform to prototype.
1664 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1666 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
1668 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
1670 * stime.c, stime.h: use SCM_P method.
1672 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1674 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
1675 be given at least two arguments. Insist that lst's last element
1676 be a list, but don't make any requirements of its predecessors.
1678 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1680 * eval.c (scm_nconc2last): Revert last change; there seems to be
1681 other stuff going on here.
1683 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1685 * eval.c (scm_nconc2last): Make sure that each element of lst
1686 (which is a list of argument lists, except for the tail) is a
1687 proper list, i.e., finite and terminated by '().
1689 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1691 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
1694 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
1695 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
1698 * vectors.c (scm_make_vector): Fill vectors with the undefined
1699 value, to help make Guile Scheme code more portable to other
1702 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
1703 * symbols.h, tags.h: Doc fixes.
1705 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
1707 * async.c (scm_take_signal): Doc fixes.
1709 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
1711 * numbers.c (scm_divbigint): When the remainder is zero, we don't
1712 want to subtract it from the modulus; we just want to leave it
1715 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
1717 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
1720 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
1722 * throw.c (scm_catch_apply): Finished implementation of
1725 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
1727 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
1729 (scm_init_filesys): set "i/o-extensions" feature.
1732 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
1734 * Makefile.in (root.o): Correct dependencies.
1736 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
1738 * Makefile.in: Added dependency entry for root.o.
1740 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
1741 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
1743 * init.c (scm_start_stack): Set initial root continuation number
1746 * procs.c: New function: scm_thunk_p.
1748 * procs.h: Added declarations of scm_thunk_p.
1750 * root.c: Renamed `call-with-new-root' -->
1751 `call-with-dynamic-root'.
1752 (cwdr): Removed allocation of new root state. This should be done
1753 separately by use of scm_make_root.
1754 (scm_apply_with_dynamic_root): New function: Does what it
1755 sounds like. Needed when spawning threads.
1757 * root.h: Added member last_debug_frame to root state.
1758 Added #include "libguile/debug.h"
1760 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
1761 arguments. The motivation is that code in root.c needs catch
1762 functionality, and we want to avoid code duplication.
1763 New functions: scm_catch, scm_lazy_catch. These are wrappers for
1764 scm_catch_apply. scm_lazy_catch is intended to introduce catch
1765 handlers that run without popping the stack into the dynwind
1768 * throw.h: Added prototypes for scm_catch_apply and
1771 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1773 * root.h (scm_root, scm_set_root): Decouple thread support details
1774 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
1775 SCM_SET_THREAD_LOCAL_DATA.
1777 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
1778 and tortoise scanning loop.
1780 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
1782 * Makefile.in: Rebuild dependencies.
1784 * libguile.h: #include "libguile/print.h" before "smob.h", since
1785 the latter uses the print_state structure.
1787 * throw.c (scm_ithrow): Use the correct variable when checking to
1788 see if a given element of scm_dynwinds is a valid catch.
1790 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
1791 structure, abort; don't just silently ignore the garbage.
1793 * _scm.h: #include "print.h" here, since it seems to be used just
1795 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
1796 strports.c, unif.h: Don't #include "print.h".
1798 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1800 * feature.h (scm_loc_features): Removed external declaration.
1801 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
1803 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1805 * feature.c (scm_init_feature): Added threads feature (needs to be
1806 initialized here, since features doesn't exist when
1807 scm_init_threads is called).
1809 * libguile.h: Added #include "libguile/../threads/threads.h".
1810 (This is a kludge to get thread support working. This should be
1813 * configure.in, acconfig.h: Added flags for thread support.
1815 * scmsigs.c: Define `signal' to be `pthread_signal' if using
1818 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
1819 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
1822 * _scm.h: Added conditional #include "threads.h"
1824 * __scm.h (SCM_ASYNC_TICK): Added call to macro
1825 SCM_THREADS_SWITCHING_CODE.
1827 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
1828 allocate the basic dynamic root object.
1829 (scm_boot_guile): Added call to scm_init_root.
1831 * root.c, root.h: Added root smob.
1832 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
1833 functions: Implements dynamic roots mostly according to spec in
1834 SCM manual. Main difference is that the second argument is a
1835 throw handler rather than an error "thunk".
1837 * root.h: Added declaration of scm_init_root.
1839 * root.c: Added #include "genio.h", #include "smob.h", #include
1840 "pairs.h", #include "throw.h", #include "dynwind.h", #include
1842 (scm_init_root): Added #include "root.x".
1844 * throw.c: Added #include "stackchk.h"
1845 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
1846 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
1847 can be used in scm_call_with_new_root; Added reenabling of stack
1848 checking when catching a throw.
1850 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
1852 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
1854 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
1855 element is not found, as per R4RS.
1857 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1859 * list.c: Doc fixes throughout.
1861 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1863 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
1864 declare the char * to be const. Avoids a warning in rgx.c.
1866 * ports.h: spelling fix.
1868 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
1871 * load.c (scm_sys_try_load_path): throw an error if file not found
1872 (like it says it in NEWS).
1874 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1876 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
1877 PROPS slot to '(), not #f; it's an empty alist.
1879 * throw.h, throw.c: Use SCM_P instead of #if hair.
1881 Remove special support for uncaught throws; see throw.c for
1883 * throw.c (uncaught_throw): New function.
1884 (scm_ithrow): Call uncaught_throw if we don't find a throw
1885 target; don't mess with scm_bad_throw_vcell.
1886 (scm_bad_throw_vcell): Variable deleted.
1887 (scm_init_throw): Don't initialize it.
1889 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
1892 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1894 * numbers.c (scm_istr2int): If the number is short (as most
1895 numbers are), just call scm_small_istr2int to deal with it.
1896 (scm_small_istr2int): New function, created by un-#ifdefing the
1897 non-bignum version of scm_istr2int and renaming it.
1899 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
1901 * load.c (scm_sys_try_load): don't check whether value returned
1902 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
1903 Change the Scheme name from %try-load to primitive-load.
1905 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
1906 Can avoid passing a message, allowing it to be derived in the
1907 error handler (e.g., if we want to throw to the key both from
1910 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
1912 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
1913 references now have a new appearance which is more compact and
1914 also gives a clue about what the target of the reference is.
1915 By setting parameters in the print state, more fancy printing can
1916 be achieved. This is used by the (not yet commited) backtrace
1919 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
1921 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
1924 * print.c: Added #include "struct.h". Removed function
1927 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
1928 scm_iprin1. Removed prototype for scm_prlist.
1930 * arbiters.c (prinarb),
1931 async.c (print_async),
1932 debug.c (prindebugobj, prinmemoized),
1933 eval.c (prinprom, prinmacro),
1934 filesys.c (scm_fd_print, scm_dir_print),
1936 mallocs.c (prinmalloc),
1937 numbers.c, numbers.h (scm_floprint, scm_bigprint),
1938 smob.h (scm_smobfuns),
1939 srcprop.c (prinsrcprops),
1941 unif.c, unif.h (scm_raprin1, rapr1),
1942 variable.c (prin_var): Changed argument `int writing' to
1943 `scm_print_state *pstate'.
1945 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
1946 that it will be called before scm_init_print.
1948 * print.c (scm_prin1): Print states are now allocated when calling
1949 scm_prin1 and then passed around to all printing functions as an
1950 argument. A cache `print_state_pool' enables reuse of print
1952 (scm_make_print_state): New function.
1953 (scm_iprin1): Adaption to print states.
1954 (scm_iprlist): An initial "hare and tortoise" scan brings down
1955 time complexity to O (depth * N). (Better time complexity will be
1956 achieved when the printing code is completely rewritten.)
1958 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1960 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
1961 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
1962 it gets done whether or not the cache variable has a value.
1964 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
1966 Distinguish #f and ().
1967 * __scm.h: #undef SICP.
1968 * pairs.h (SCM_EOL): Delete this definition, equating it with
1970 * tags.h (SCM_EOL): Give it a new definition here; I think I found
1971 the value it used to have. Doc fixes, too.
1973 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
1975 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
1976 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
1977 Lord's implementation of structs, allowing for tail arrays as
1978 described in the manual. Also fixed some bugs. (Both the interface
1979 and the implementation should be improved.)
1981 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
1983 * print.c, print.h: Closures now print like #<procedure foo (x)>.
1984 People who whish to see the source can do `(print-enable 'source)'.
1985 Removed #ifdef DEBUG_EXTENSIONS.
1987 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1989 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
1990 integer (assuming for now accepting an integer is a good thing).
1992 * error.c, fports.c: replace use of %S in lgh_error args with %s.
1993 %S will be used instead for write'ing arguments.
1995 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
1996 asserts. fix a few other asserts.
1997 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
1998 scm_uniform_vector_ref, scm_array_set_x,
1999 scm_dimensions_to_unform_array): change args in
2000 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
2001 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
2002 scm_substring_fill_x): likewise.
2003 gsubr.c (scm_gsubr_apply): likewise.
2004 eval.c (SCM_APPLY): likewise.
2006 * eval.c (4 places): replace scm_everr with lgh_error or
2009 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
2010 scm_memory_error): new procedures.
2011 scm_everr: deleted. can use scm_wta, dropping first two args.
2012 scm_error: convert NULL subr to SCM_BOOL_F.
2014 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
2017 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
2020 * error.c, error.h: new error keys: scm_arg_type_key,
2021 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
2023 scm_wta: reimplement using lgh_error instead of scm_everr.
2025 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
2027 * gdbint.c: scm_lread now has one more argument.
2029 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
2030 scm_port_\1; Added mutator scm_set_port_filename_x (used when
2031 loading source from non-file ports, which, e. g., happens when
2032 using the Emacs interface).
2034 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
2037 * read.c: Added code for recording of positions of source code
2038 expressions; New functions: recsexpr, scm_lreadrecparen;
2039 _scm_make_srcprops --> scm_make_srcprops
2040 (scm_flush_ws): Removed updating of positions counters. This work
2041 is already done by scm_gen_getc
2043 * read.h: Added prototype for scm_lreadrecparen
2045 * print.c: Added #include "alist.h"
2047 * eval.c: Added #include "hash.h"

2054 (scm_init_srcprop): Adjusted size of initial source-whash. Name
2055 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
2056 --> scm_make_srcprops
2058 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
2059 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
2060 function calls in the definition of the whash access macros.
2062 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
2064 * init.c (scm_boot_guile): Add level of indirection to
2065 scm_boot_guile_1() to ensure that stack base pointer is properly
2066 initialized. There was no guarantee that variable i was the
2067 highest/lowest variable on stack (i.e. the call frame of
2068 scm_boot_guile was not completely protected from gc).
2070 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
2072 * ports.h (scm_port_table): put back file_name, it will be used to
2073 support debugging. Undo related changes in fports.c, ioext.c,
2076 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2078 * ports.h (scm_port_table): remove file_name member for now, it seems
2080 * fports.c (scm_open_file): don't set file_name in PTAB.
2081 (prinfport): don't use file_name in PTAB.
2082 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
2083 * ports.c (scm_add_to_port_table): don't intialize file_name.
2084 (scm_port_file_name): remove for now.
2085 * gc.c (scm_gc_mark): don't mark PTAB file_name.
2087 * fports.h (scm_mkfile): prototype deleted.
2088 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
2090 * debug.c, unif.c: use scm_out_of_range instead of
2091 wta for range errors (ASSERT still needs work).
2093 * error.c, error.h (scm_out_of_range): new procedure.
2095 * error.c, error.h (scm_out_of_range_key): new key.
2097 * posix.c (scm_sync): #else was missing.
2099 * error.c, error.h: append _key to names scm_num_overflow and
2102 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
2103 of consing an empty list.
2104 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
2105 of macros, saves code and string space.
2106 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
2107 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
2108 lower case. Rename scm_syserror_m to scm_syserror_msg.
2109 error.h: prototypes for new procedures.
2111 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
2113 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
2115 * error.c, error.h: setup scm_num_overflow key.
2117 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
2118 Remove definition of SCM_OVSCM_FLOW.
2120 * fports.c (scm_open_file): use SCM_SYSERROR_M.
2122 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
2123 explicit message and args.
2125 * error.c, error.h, __scm.h: change system_error_sym to
2128 * error.c (system_error_sym): remove leading %% from the Scheme name
2131 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
2133 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2135 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
2136 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
2137 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
2138 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
2139 renamed. (These were introduced by unsupervised name
2142 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2144 * print.c: Added code for detection of circular references during
2145 printing. (init_ref_stack, grow_ref_stack): New functions. Added
2146 a hook for printing of closures (accessible via print options).
2147 This leads to a split of calls to scm_iprin1 into two classes:
2148 elementary print operations (e. g. the code which prints a smob)
2149 still use scm_iprin1 while top level calls (like scm_display) use
2150 scm_prin1. scm_prin1 begins by clearing the data structure used
2151 to record reference information.
2153 * print.h: Added declarations of scm_prin1 and scm_prlist.
2155 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
2157 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
2159 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
2161 * error.c (err_head): scm_iprin1 --> scm_prin1
2163 * debug.c: Adjusted header comment.
2167 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2169 * strerror.c: Doc fix.
2171 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2173 * gdbint.c (gdb_read): Now possible to run during GC.
2174 (unmark_port, remark_port): New functions.
2176 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
2178 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
2179 of allocating a new string object. Also, increase size by
2180 the factor 2 instead of 1.5.
2182 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
2184 * __scm.h (SCM_P): Corrected to run under traditional C.
2186 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
2189 * async.c: Calls to scm_sysintern corrected.
2191 * async.h (scm_async_clock): Redundant declaration removed.
2193 * continuations.c (scm_dynthrow): Redundant declaration removed.
2195 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
2196 Definition typos corrected.
2198 * debug.h: Missing declarations of functions in debug.c added
2201 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2202 Missing declarations to functions in eval.c added.
2204 * filesys.c: Possibly uninitialized variable rv.
2206 * gc.h (scm_object_addr, scm_unhash_name): Missing
2207 declarations of functions defined in gc.c added.
2209 * genio.c: Possible typos str_data -> wstr_data. ???
2211 * genio.c: Possibly unintended shadowing of local variable
2212 `int c' (gotos out of scope of inner `c'). ???
2214 * init.c: Uninitialized `SCM last' may be used.
2216 * ioext.h: (scm_sys_isatty_p): Typo.
2218 * list.h (scm_list_head): Missing prototype for function in
2221 * numbers.c (scm_two_doubles): Changed from extern to static
2222 (is used only within numbers.c).
2224 * numbers.h: Repeated declarations removed.
2226 * ports.h (scm_close_all_ports_except): Declaration for the
2227 function defined in ports.c added.
2229 * posix.h: Missing declarations added.
2231 * procs.h (scm_make_subr_opt): Missing declaration added.
2233 * socket.h (scm_sys_gethost): Missing declaration added.
2235 * socket.h: Redundant declarations removed (they are in fdsocket.h).
2237 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
2238 Missing declarations added.
2240 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
2242 * struct.c: Uninitialized variable `SCM answer' may be used.
2244 * unif.c (l2ra): Declaration prototype.
2246 * unif.c (scm_array_equal_p): Dummy definition removed (it is
2247 defined in ramap.c).
2249 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
2250 Redundant declarations removed (they are in ramap.h).
2252 * variable.h (scm_make_udvariable,
2253 scm_make_undefined_variable): Declaration corrected to
2254 correspond variable.c.
2256 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
2257 Missing declarations added.
2259 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
2261 * Makefile.in (distclean): Don't forget to delete fd.h.
2263 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2265 * fd.h.in, tags.h: Trivial cleanups.
2267 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
2268 marksweep.h just declared functions from gc.c.
2269 * gc.h, libguile.h: Don't #include "marksweep.h".
2270 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2271 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
2272 dependencies updated.
2274 * libguile.h: Don't #include "files.h"; it's been deleted.
2276 * files.c (scm_sys_delete_file): Moved to filesys.c.
2277 File is now empty; deleted.
2279 * filesys.c: scm_sys_delete_file is now here. Remove
2280 #if's; they seem to rely on remnants of an old portability
2281 regimen. If the problems come up again, solve them properly,
2282 using autoconf. Specifically: Don't test M_SYSV, and #define
2283 remove to be unlink if it's #defined; don't use remove just
2284 because HAVE_STDC_HEADERS is #defined.
2285 * filesys.h: Add declarations for scm_sys_delete_file.
2286 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2287 files.o, files.h, files.c, and files.x.
2288 * init.c: Don't #include "files.h", and don't call scm_init_files.
2290 Use SCM_P instead of PROTO; the latter intrudes on the user's
2292 * params.h: Deleted; definition of SCM_P moved to...
2293 * __scm.h: ... here, where it replaces PROTO macro.
2294 * libguile.h, smob.h: Don't #include "params.h".
2295 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
2296 smob.h: Fix prototypes accordingly.
2297 * Makefile.in: Update dependencies.
2298 (inner_h_files): Remove params.h.
2300 * gc.c: #include "gc.h"; every module should include its header,
2301 to let the compiler cross-check the declarations against the
2304 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2305 simpos.h: #include "libguile/__scm.h".
2307 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2309 * init.c: Don't forget to #include smob.h and init.h.
2310 * Makefile.in: Dependencies updated.
2312 * smob.h: Use PROTO instead of #if __STDC__.
2314 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2316 * __scm.h: Doc fixes.
2318 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2319 <angles>; this allows `make depends' to work properly.
2321 * libguile.h: #include smob.h and pairs.h before the others; they
2322 define typedefs used by other headers.
2324 C files should #include only the header files they need, not
2325 libguile.h (which #includes all the header files); the pointless
2326 recompilation was wasting my time.
2327 * Makefile.in (all .o dependency lists): Regenerated.
2328 * libguile.h: Don't try to get a definition for size_t here...
2329 * __scm.h: Do it here.
2330 * _scm.h: Since this is the internal libguile header, put things
2331 here that all (or a majority) of the libguile files will want.
2332 Don't #include <libguile.h> here; that generates dependencies on
2333 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2334 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2335 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

2421 * symbols.c: Get "symbols.h", "mbstrings.h", "alist.h",
2422 "variable.h", "eval.h", "chars.h".
2423 * tag.c: Get "tag.h", "struct.h", "chars.h".
2424 * throw.c: Get "throw.h", "continuations.h", "debug.h",
2425 "dynwind.h", "eval.h", "alist.h", "smob.h", "genio.h".
2426 * unif.c: Get "unif.h", "feature.h", "strop.h", "sequences.h",
2427 "smob.h", "genio.h", "eval.h", "chars.h".
2428 * variable.c: Get "variable.h", "smob.h", "genio.h".
2429 * vectors.c: Get "vectors.h", "eq.h".
2430 * version.c: Get "version.h".
2431 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
2432 * weaks.c: Get "weaks.h".
2434 * stackchk.h: #include "libguile/debug.h",
2436 * print.h, read.h: #include "options.h", since everyone who uses
2437 either of these files will need that.
2439 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2440 anyone who uses this file will need them to define the smob
2441 printing functions. Also, get markers.h, since people will need
2442 to #define the mark functions.
2444 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2445 * ports.h: ... to here.
2447 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2448 don't rely on archaic C default type rules.
2450 * fports.h: #include "libguile/ports.h", since you need that in
2451 order to parse this.
2453 * genio.h: #include "libguile/print.h", because you need that to
2454 parse this; don't bother #including "ports.h", since print.h gets
2457 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2459 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2460 this; it's now a reference to an element of *scm_root.
2462 * debug.h: Don't #include "options.h"; the compiler won't be able
2463 to find that once the headers are installed; instead, #include
2464 "libguile/options.h".
2465 * gc.h: Same, with marksweep.h.
2466 * mbstrings.h: Same, with symbols.h.
2467 * scmhob.h: Same, with _scm.h.
2468 * smob.h: Same, with params.h.
2470 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2471 C files; there's no need for this, and it forces recompilations
2474 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2476 * error.c (scm_error): declare scm_error_callback.
2478 * error.h: prototype for scm_error_callback.
2480 * __scm.h: define lgh_error.
2481 (SCM_SYSERROR): redefine using lgh_error.
2483 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2485 * error.c (scm_error): new procedure.
2487 * error.h: prototype for scm_error.
2489 * Makefile.in (install): install scmconfig.h from the current
2490 directory, not $(srcdir).
2492 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2494 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2495 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2496 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
2497 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
2498 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
2499 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2500 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2501 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2502 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2503 vports.h, weaks.h: #include "libguile/__scm.h", not
2504 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2505 dependencies are within libguile properly.
2507 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2509 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2510 when scmconfig.h doesn't exist.
2512 * load.c (scm_sys_try_load): Correct spelling.
2514 * feature.c (scm_loc_features): Make this static.
2516 * Makefile.in (libpath.h): Omit trailing slash from path. We
2517 shouldn't require it of users, so why put it here?
2519 Move code to initialize and search %load-path from ice-9 to C
2520 code, so we can use the load-path to find the ice-9 boot code;
2521 this makes it easier to run Guile without installing it. See
2522 corresponding changes in guile/Makefile.in.
2523 * feature.c: Move stuff concerned with the load path to load.c.
2524 (scm_compiled_library_path): Deleted.
2525 Don't #include libpath.h here.
2526 * feature.h: Don't mention scm_compiled_library_path.
2527 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2528 <sys/stat.h>, and <unistd.h> (if present).
2529 (R_OK): #define if the system hasn't deigned to.
2530 (scm_loc_load_path): New variable.
2531 (scm_init_load_path, scm_sys_search_load_path,
2532 scm_sys_try_load_path): New functions.
2533 (scm_init_load): Initialize scm_loc_load_path to point to the
2534 value cell of the Scheme %load-path variable.
2535 * load.h: Add declarations for scm_sys_search_load_path,
2536 scm_sys_try_load_path.
2537 * init.c: Call scm_init_load_path.
2538 * Makefile.in (feature.o, load.o): Dependencies updated.
2540 * load.c, load.h: Rewrite using PROTO macro.
2542 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2544 * gc.c (scm_cellp): New function: C predicate to determine if an
2545 SCM value can be regarded as a pointer to a cell on the heap.
2547 * gc.h: Added declaration of scm_cellp.
2549 * gdb_interface.h: New file: The GDB interface header from the GDB
2552 * gdbint.c: New file: GDB interface.
2554 * gdbint.h: New file: GDB interface.
2556 * libguile.h: Added #include <libguile/gdbint.h>.
2558 * init.c (scm_boot_guile): Added scm_init_gdbint.
2560 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2561 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2562 found if object files and source are kept separate).
2564 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2566 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2568 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2570 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2571 TK_SRC_DIR; they're not relevant any more.
2573 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2574 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2576 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2578 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2579 search path, so we can find the <libguile/MUMBLE.h> headers.
2581 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2583 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2584 implicit in the .c.o rule.
2585 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2588 Put the library path in a header file, instead of passing it on
2589 the command line in every compilation.
2590 * Makefile.in (libpath.h): New target.
2591 (feature.o): Depend on libpath.h.
2592 (clean): Delete libpath.h.
2593 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2594 * feature.c: ... #include "libpath.h" here.
2595 * .cvsignore: Ignore libpath.h.
2597 Don't install the unwashed masses of Guile header files in the
2598 main #include path; put most of them in a subdirectory called
2599 'libguile'. This avoids naming conflicts between Guile header
2600 files and system header files (of which there were a few).
2601 * Makefile.in (pkgincludedir): Deleted.
2602 (innerincludedir): New variable; this and $(includedir) are enough.
2603 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
2604 (installed_h_files): Divide this up. Now this variable lists
2605 those header files which should go into $(includedir) (i.e. appear
2606 directly in the #include path), and ...
2607 (inner_h_files): ... this new variable says which files appear in
2608 a subdirectory, and are referred to as <libguile/mumble.h>.
2609 (h_files): List them both.
2610 (install): Create innerincludedir, not pkgincludedir. Put
2611 the installed_h_files and inner_h_files in their proper places.
2612 (uninstall): Corresponding changes.
2613 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2614 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2615 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
2616 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
2617 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
2618 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2619 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2620 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2621 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2622 vports.h, weaks.h: Find __scm.h in its new location.
2623 * __scm.h: Find scmconfig.h and tags.h in their new locations
2624 (they're both "inner" files).
2626 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
2628 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
2630 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2632 * posix.c: Doc fixes.
2634 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
2636 * socket.c: Don't include a prototype for inet_aton; just use a
2637 K&R style declaration, to avoid warnings but minimize the chance
2638 of conflicts with the system.
2640 On NextStep, <utime.h> doesn't define struct utime, unless we
2641 #define _POSIX_SOURCE before #including it.
2642 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
2643 * acconfig.h: New comment text for above CPP symbol.
2644 * configure.in: Call it.
2645 * posix.c: #define _POSIX_SOURCE if it seems necessary.
2647 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
2649 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
2650 testing for __EMX__.
2652 * posix.c: #include <libc.h>, if it exists.
2654 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
2655 don't even know if the latter exists.
2657 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
2658 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
2659 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
2661 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
2663 (scm_init_posix): Use them when initializing the Scheme constants
2666 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2668 * Makefile.in (libdir, includedir, bindir): Use the
2669 autoconf-supplied values, instead of deriving them ourselves.
2670 (pkgincludedir, datadir, pkgdatadir): New variables.
2671 (install, uninstall): Put the header files in a special
2672 subdirectory, not in the main search path.
2674 * Makefile.in (ALL_CFLAGS): Provide the proper value for
2675 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
2677 * Makefile.in (IMPLPATH): Deleted; never used.
2679 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
2680 on the Tcl/Tk source any more.
2681 (INCLUDE_CFLAGS): Remove references to the above.
2683 * Makefile.in (version.o): Corrected dependencies.
2685 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
2687 * libguile.h: #include "version.h"
2689 * init.c (scm_boot_guile): Call scm_init_version.
2690 * gscm.c (gscm_run_scm): Call scm_init_version.
2692 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
2693 GUILE_VERSION): AC_DEFINE these.
2694 (acconfig.h): #undef the above symbols.
2696 * Makefile.in (libobjs): Add version.o.
2697 (installed_h_files): Add version.h.
2698 (c_files): Add version.c.
2699 (gen_c_files): Add version.x.
2700 (version.o): New rule.
2701 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
2702 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
2703 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
2704 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
2705 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
2706 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
2707 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
2708 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
2709 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
2710 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
2711 weaks.o): Add version.h to dependency lists.
2712 (markers.o): Remove duplicate rule.
2714 * version.h: New file.
2716 * version.c: New file.
2718 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2720 * symbols.c (scm_strhash): scm_downcase is now a function, not an
2721 array; use it appropriately. Since GCC is quite happy to
2722 subscript functions, it never warned us about this; we should use
2723 -Wpointer-arith in the future. I guess we never tested
2726 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2728 * socket.c: Doc and copyright fixes.
2730 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2732 * debug.c: Fixed and improved gdb support.
2734 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2736 * socket.c: Added declaration of inet_aton to avoid compiler
2737 warning. (Hope this solution is correct.)
2739 * stime.c: Added declaration of ftime. (This is missing in
2742 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
2744 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2746 * Makefile.in (c_files): add strerror.c.
2748 * strerror.c: new file from Emacs' sysdep.c.
2749 maybe configure should also check for sys_errlist.
2751 * configure.in (AC_REPLACE_FUNCS): add strerror.
2753 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2755 * debug.c (scm_init_debug): Added initialization for
2756 scm_evaluator_traps.
2758 * debug.h, debug.c: Various name changes.
2759 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
2760 "debug-options-interface". See commentary in options.c.
2762 * options.h, options.c: Options now have documentation strings.
2763 Also added a long explanatory commentary.
2765 * eval.c, print.h, print.c, read.h, read.c: Modifications to
2768 * gscm.c, init.c, root.c, throw.c: Bug fixes:
2769 last_debug_info_frame is now updated in all cases.
2771 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
2774 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2776 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
2777 Added option STACK_CHECKING.
2779 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
2781 * Makefile.in: Added {debug,options,srcprop}.{h,c}
2783 * __scm.h: Removed symbols for debugging support.
2785 * acconfig.h: Added symbols for debugging support.
2787 * configure.in: Added user option for debugging support.
2788 --enable-debug will include the debugging code into libguile.a.
2790 * continuations.c (scm_make_cont): Enlarged the #if 0 around
2791 scm_relocate_chunk_to_heap.
2793 * debug.c: New file: low-level debugging support. It also
2794 includes support for debugging with gdb. (The extensions to gdb
2795 are written by Per Bothner at Cygnus.)
2797 * debug.h: New file: low-level debugging support.
2799 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
2800 argument pairs. Extensive modifications to the debugging
2801 evaluator. Added "SECTION:" commentaries to clarify what happens
2802 when, during double compilation. Renamed EVALIMP --> EVALIM.
2803 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
2804 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
2805 the beginning of the file. New procedure: scm_unmemocopy.
2806 Added some global state variables needed by the debugging
2807 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
2808 check_entry, check_apply, check_exit, debug_options and
2809 evaluator_traps. New acro: undefine.
2811 * eval.h: Renamed EVAL --> XEVAL.
2813 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
2814 --> scm_make_weak_key_hash_table.
2816 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
2817 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
2819 * libguile.h: Conditionally include debug.h
2821 * objprop.c (scm_object_properties, scm_set_object_properties_x):
2822 scm_object_properties shouldn't return handle. `handle' now gets
2823 initialized in scm_set_object_properties_x. scm_object_properties
2824 doesn't any longer create an entry in scm_object_whash.
2826 * options.c: New file: handling of run time options.
2828 * options.h: New file: handling of run time options.
2830 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
2832 * print.c: New procedure: scm_print_options
2834 * print.h: Defines for print options.
2836 * read.c: New procedure: scm_read_options
2838 * read.h: Defines for reader options.
2840 * root.h: Added scm_source_whash among scm_sys_protects.
2842 * srcprop.c: New file: source properties.
2844 * srcprop.h: New file: source properties.
2846 * throw.c (jbsmob): Jump buffers are now correctly allocated.
2847 (Bug found by A. Green.)
2849 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2851 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2853 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
2855 * libguile.h: #include "objprop.h"; I guess this was forgotten.
2857 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
2858 and should be called by the final client.
2860 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
2862 * gc.h: Use the PROTO macro when declaring functions.
2863 * gc.c: Use the PROTO macro when declaring static functions.
2864 Remove the CPP hair around function definitions.
2866 * gc.c (scm_init_storage): Initialize scm_asyncs.
2868 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
2869 preprocessor symbol; "__scm.h" is where it might get #defined.
2870 * __scm.h: Similar: #include <scmconfig.h> before testing
2873 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
2875 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
2877 * init.c (scm_boot_guile): Add init_func argument; call
2878 (*init_func) instead of calling scm_appinit; it's ucky to
2879 hard-code names for the user's procedures.
2880 * init.h (scm_boot_guile): Adjust declaration.
2882 * __scm.h (PROTO): New macro, for declaring functions with
2885 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
2886 eliminate all the __STDC__ conditionals.
2887 (scm_boot_guile): Add declaration.
2888 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
2889 Remove __STDC__ conditionals around function definitions; the
2890 declarations in init.h will provide the same information, more
2893 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
2894 complain about it in the error message; the error message is
2895 adequate without that note, and there's nothing the user can do
2898 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
2900 * Makefile.in (ancillary): Drop def.sed.
2902 * posix.c (scm_init_posix): Use numeric values, rather than
2903 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
2904 F_OK. The symbols aren't available on some systems, and I'm
2905 pretty sure their values are fixed by common widespread practice.
2906 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
2908 More functions unavailable on some systems.
2909 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
2910 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
2912 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2913 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
2914 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
2915 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
2916 stub that signals an error as the #else.
2918 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
2920 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
2922 * Fixes motivated by Petr Adamek <adamek@mit.edu>:

2953 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
2955 * fdsocket.c (getsockopt, setsockopt): change type of optlen from

2958 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
2959 from scm_sizet to int.
2961 * error.c: include unistd.h.
2963 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
2966 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
2968 * __scm.hd, def.sed: deleted.
2970 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
2972 Changes for NeXT, suggested by Robert Brown.
2973 * configure.in: Call AC_TYPE_MODE_T.

2975 NeXT. Put header file list in alphabetical order.
2976 * configure, scmconfig.h.in: Regenerated.
2977 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.

2999 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
3001 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
3003 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
3005 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
3007 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3009 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
3010 This is necessary on Ultrix, and doesn't hurt portability.
3012 * Makefile.in (dist-dir): New target, implementing a new dist system.
3013 (installed_h_files): Put in alphabetical order.
3014 Remove duplicate entries for markers.h and unif.h.
3015 (c_files): Remove duplicate entries for markers.c.
3016 (ancillary): Renamed from anillery; all uses changed. Remove
3017 PLUGIN; it's a directory, and needs special treatment in dist-dir.
3018 Remove all the ../doc/* files; doc/Makefile.in handles that.
3020 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
3022 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
3023 every if must have an else, or else the whole command has a
3024 non-zero exit code whenever the if's condition is false.
3026 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
3028 * posix.c: include string.h.

3035 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
3036 Remove leading % from scheme names.
3037 Do not return error values, call SCM_SYSERROR or similar.

3088 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
3090 * ports.c (scm_ports_prehistory): size malloced here doesn't
3091 matter so long as it is non-0 (got rid of "* 4").
3093 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
3095 * gscm.h: gscm_mkarray eliminated (presumably was not being used
3096 since its definition was bogus).
3098 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
3100 * mallocs.[ch]: back again (for rx at least).
3102 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
3104 * ports.c: removed functions relating to the mapping between ports
3105 and descriptors. (That stuff is unix-specific and should be collected
3106 in a separate library).
3108 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
3109 (Tom Mckay@avanticorp.com)

3113 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
3114 handled correctly (SCM_FREEP was applied to them) -- test for
3115 NIMP. Keys in weak hash tables were spuriously (though harmlessly)

3160 (possibly triggering gc) before setting the tag of the corresponding
3163 * pairs.c (scm_delq_x): never throw an error.
3165 * vectors.c (scm_make_vector): made the default vector fill argument
3166 into '() (much more useful than the previous value, "#unspecified")

3170 * ports.c (scm_add_to_port_table): Added fields
3171 to port table entries: file_name, line_num, col.
3172 Update these in open_file, gen_getc and gen_ungetc.
3173 Added procedures to access those fields.
3175 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>

3283 initialization to fix a race condition.
3285 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

3309 set the multi_byte flag correctly in symbols. This is wrong.
3310 intern_obbary_soft and msymbolize should take an extra parameter.
3311 Also, weird multibyte symbols don't print correctly.
3312 The weird symbol syntax is also a bit bogus (emacs doesn't quite
3315 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
3317 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means

3320 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
3322 * strings.c (scm_make_shared_substring): build'em.
3323 It might better to keep a table of these and use one
