1 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
4 (SCM_KEYWORD_STYLE): defined.
6 * read.c (scm_read_opts): add a keywords option. This isn't a
7 boolean option, in case someone wants to add support for DSSSL
9 Setup scm_keyword_prefix symbol.
10 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
12 * I've left keyword support disabled by default, since it doesn't
13 seem to break the module system and it gives R4RS standard behaviour.
14 It can be reactivated with (read-set! keywords 'prefix).
16 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
18 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
19 before constructing arbiter.
21 * eval.c (scm_m_define): Bugfix: Check that the object is a
22 closure before setting the procedure property!
24 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
26 * ports.c: Removed `ungetc-char-ready?'.
28 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
30 * read.c (scm_init_read): intitialise scm_read_hash_procedures
31 (idea from Mikael: make it a pair so scm_permanent object only
33 (scm_read_hash_extend): don't call scm_permanent_object.
34 (ideas from Mikael): if chr is already in the list, replace its
35 procedure instead of appending it again. If proc is #f, remove
37 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
39 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
41 * gdbint.c (gdb_read): update scm_lreadr usage.
43 * load.h: update prototypes.
45 * load.c (scm_primitive_load, scm_read_and_eval_x,
46 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
48 * read.h: add prototype for scm_read_hash_extend. Change args for
51 * read.c (scm_read_hash_procedures): new variable.
52 (scm_read_hash_extend): new procedure.
53 (scm_get_hash_procedure): new procedure.
54 * (scm_lreadr): use scm_get_hash_procedure instead of an argument
55 for extended # processing.
56 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
57 scm_read_token): remove case_i, sharp arguments. Change callers.
59 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
61 * read.h (SCM_N_READ_OPTIONS): increase to 3.
62 (SCM_CASE_INSENSITIVE_P): define.
64 * read.c: add case-insensitive option to scm_read_opts.
65 * (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
66 to determine whether to convert symbol case.
67 (default_case_i): definition removed.
68 * read.c (scm_read_token): if case_i, downcase ic before doing
71 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
73 * configure.in: Added configuration option `guile-debug'.
74 Configure with --enable-guile-debug if you want a bunch of extra
75 functions used for debugging when developing Guile.
77 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
79 * procs.c (make-cclo): New undocumented debugging procedure: Make
80 compiled closure with internal procedure PROC and length LENGTH.
81 Only compiled if GUILE_DEBUG is defined.
83 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
85 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
87 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
89 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
90 with 3 or more args internally to the evaluator.
92 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
94 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
95 with 3 or more args internally to the evaluator. This is mainly
96 because we don't want to pass entry and exit points of the
97 debug support twice, but it also seems to increase the speed of
98 the evaluator for such calls (e. g. (+ 1 2 3)).
100 * * backtrace.c (scm_display_application): New procedure:
101 display-application; Set fancy printing parameters individually
102 for different types of display (backtrace, error, application).
103 (These should of course be customizable!)
105 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
106 clear the CHECK-flags.
108 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
110 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
112 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
114 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
115 from pairs with a GLOC in the car.
117 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
118 otherwise `symbol-hash' will behave badly.
119 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
120 we get segmentation fault!
122 * * symbols.c: Added #include "weaks.h". New functions:
123 `builtin-bindings' and `builtin-weak-bindings'. (These will be
124 moved to an extraneous library when we split libguile.)
126 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
128 * filesys.c (scm_stat): stat now takes fport arguments too as
129 documented in the manual.
131 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
133 * debug.c (scm_single_step): Bugfix: Call continuation with
134 scm_call_continuation instead of throwing to it.
136 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
138 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
139 argument wasn't declared to be optional.
141 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
143 * stime.c (scm_init_stime): Add feature "current-time".
145 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
147 * throw.h: prototype for scm_exit_status.
148 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
149 args to derive an exit status. Allows (quit) to work from a
151 (scm_exit_status): new function.
154 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
156 * eval.c (scm_deval): Removed some old code.
157 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
159 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
162 * symbols.c (msymbolize): Bugfix: Must initialize property list to
165 * procs.c: Introduce the existent C function scm_thunk_p at the
166 Scheme level as well.
168 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
170 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
171 used from C to easily lookup the value of a symbol in the current
174 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
176 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
177 scm_init_unif in this file. This will also fix a previous problem
180 * configure.in: Added AM_MAINTAINER_MODE
182 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
184 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
187 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
189 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
190 source files that are not always included in libguile but should
191 have their dependencies calculated by automake. This variable is
192 recognized by automake, no further magic is needed.
193 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
194 to deal exclusively with *.lo files, as it seems. The *.o files
195 are built automatically when the corresponding *.lo file gets
198 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
200 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
203 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
205 * unif.c (scm_array_set_x): minor change to argument error checking.
207 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
209 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
210 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
211 They should only be included in the library at configure.in's
213 (libguile_la_LDADD): Include the appropriate .lo files here.
214 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
215 so we know when to build them (and their .lo bretheren).
216 * configure.in (LIBLOBJS): New substituted variable. We let
217 configure decide which .o files to include in LIBOBJS, and then
218 put the corresponding list of .lo files in LIBLOBJS. The latter
219 is what we pass to libtool.
220 * Makefile.in, configure: regenerated.
222 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
224 * symbols.c (scm_sysintern0): New function. Contains the core of
225 old scm_sysintern but doesn't take a second value argument.
226 (scm_sysintern): Now uses scm_sysintern0.
227 (scm_sysintern_no_module_lookup): Renamed to
228 scm_sysintern0_no_module_lookup and doesn't take a second value
231 * symbols.h (scm_sysintern0: Added declaration.
233 * options.c (scm_init_opts): Use scm_sysintern0 instead of
234 scm_sysintern when interning option keys. Otherwise we risk
235 destroying the values of already interned variables.
237 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
238 scheme-level boolean (use SCM_NFALSEP).
240 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
242 (scm_backtrace): New function. (C version of old function from
243 boot-9.scm) Motivation: Make it possible to display backtraces
244 without depending on boot-9.scm. (I'm uncertain if this
245 motivation is good enough...)
247 * root.h (scm_root_state): Add member the_last_stack_var.
248 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
250 * root.c (mark_root): Mark scm_the_last_stack_var.
252 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
255 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
257 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
258 1. mark_lazy_catch didn't mark the smob.
259 2. Both functions above have standard variants:
260 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
261 free_lazy_catch --> scm_free0.
263 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
265 * throw.c (scm_internal_lazy_catch): New function.
266 (scm_lazy_catch): Rewritten to use it.
267 (scm_ithrow): Handle the new lazy catch representation.
268 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
269 that doesn't have a jmpbuf is a lazy catch clause.
270 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
271 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
272 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
274 (scm_init_throw): Register the new lazy-catch smob type.
275 * throw.h (scm_internal_lazy_catch): decl for new function.
277 * throw.c (scm_internal_catch): Doc fixes.
279 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
280 configure.in. Including this might cause problems if applications
281 that link against libguile include their own copies of alloca, but
282 if they're using autoconf, they should be adding libguile to LIBS
283 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
284 the copy in libguile, and things will be okay. (I think.)
286 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
288 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
290 strop.h: move prototypes too.
292 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
294 * posix.c (scm_init_posix): don't intern EINTR since it's now done
297 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
298 etc. I deleted them from filesys.c long ago, but didn't
299 notice they were here too (although ineffective since
300 sys/stat.h wasn't included).
302 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
304 * eval.c: Don't define alloca in GCC case. gcc will automatically
305 use __builtin_alloca if appropriate.
307 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
309 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
310 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
311 that values of automatic variables are preserved. See comments
312 for safe_setjmp for details.
314 Change from Thomas Morgan:
315 * variable.c: Include eq.h.
316 (var_equal): New function.
317 (variable_smob): Use var_equal as the discriminator for variables.
319 * throw.c (s_throw): Remove extraneous declaration.
321 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
322 * eval.c: Add necessary CPP cruft to support that.
323 * configure, Makefile.in, scmconfig.h.in: regenerated.
325 Change from Thomas Morgan:
326 * procprop.c (scm_procedure_properties): Convert the Scheme
327 boolean returned by scm_procedure_p into a C boolean before using
328 it as a condition for SCM_ASSERT.
329 (scm_procedure_property): Likewise.
331 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
332 indications of Unixness.
335 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
337 * * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
339 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
341 * read.c (scm_lreadr): use scm_misc_error to improve one of the
342 "unknown # object" error messages.
344 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
345 (scm_i_index) and declare it static. Add a 'direction' argument
346 to indicate what way the search should go.
347 (scm_i_index): throw out-of-range error instead of wrong-type-arg
349 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
350 strop.h: remove scm_i_index, scm_i_rindex prototypes.
352 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
354 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
356 * * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
357 to avoid clash with various scsh forks.
359 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
361 The following two changes (ramap.c, throw.c) are motivated by the
362 apparent unportability of forward declarations of static arrays of
363 the form `static foo bar[];'.
365 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
366 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
368 * throw.c (scm_throw): Moved above scm_ithrow.
370 * options.h: Removed the extern declarations of scm_yes_sym and
371 scm_no_sym since these are static.
373 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
375 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
377 * Makefile.am: remove AWK=@AWK@.
378 Add a rule for generating errnos.list.
379 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
381 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
382 don't extract errnos, just set a variable (avoids the
383 need to recompile error.c just because configure is run.)
385 * unif.h: update prototypes.
386 * unif.c (scm_uniform_array_read,write): change the offset and
387 length arguments to start and end, for consistency.
389 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
391 * ioext.h: update prototypes.
392 * * ioext.c (scm_read_delimited_x): replaces scm_read_line and
393 scm_read_line_x, it's a more general procedure using an
394 interface from scsh. read-line and read-line! are now defined
396 * Note that the new read-line trims the terminator
397 by default, previously it was appended to the returned string. An
398 optional argument specifies how to process the terminator (scsh
399 compatible). For the old behaviour: (read-line port 'concat).
400 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
401 returns a pair, but is converted to multiple values if the scsh
404 socket.h: update prototypes.
405 * socket.c (scm_recvfrom): for consistency with other procedures,
406 take start and end as separate optional arguments.
407 * (scm_recv, scm_recvfrom): don't allow the second argument
408 to be a size, only a buffer. Change the scheme names to
409 recv! and recvfrom!. Don't return the buffer.
411 * ioext.h, posix.h: move prototypes too.
412 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
413 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
414 "read.h" and "unif.h".
415 * ioext.c: include "chars.h"
417 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
419 * dynl.c: The dynamic linking and module registration functions
420 are now defined even when dynamic linking is not available for the
421 host system. Some of their functionality can be done without
422 dynamic linking; when it's really needed, they throw errors.
424 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
426 * configure.in: Only define DYNAMIC_LINKING when one of the system
427 dependent functions is detected.
428 * dynl.c (scm_dynamic_func): New function to get the address of a
429 function in a dynamic object.
430 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
431 produced by scm_dynamic_func as the thing to call.
433 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
435 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
436 (scm_register_module_xxx, scm_registered_modules,
437 scm_clear_registered_modules): New functions.
439 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
441 * symbols.c (scm_sysintern): Renamed to
442 scm_sysintern_no_module_lookup.
443 (scm_sysintern): New function to take the place of the old
444 scm_sysintern. It uses the current toplevel lookup closure to give
445 the symbol its value. This is a temporary hack to put packages
446 like gtcltk into their own module.
447 (scm_can_use_top_level_lookup_closure_var): New variable to tell
448 us whether `scm_top_level_lookup_closure_var' has been initialized
450 * eval.c (scm_init_eval): Set it.
452 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
454 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
455 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
457 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
459 * (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
460 scm_sys_dup): deleted: FD capability will be added to other
462 * Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
463 scm_fd_free, fd_smob, scm_intern_fd.
464 * (scm_open): renamed from scm_sys_open. Return a port instead of
465 an FD object. Make the mode argument optional.
466 * (scm_sys_create): deleted, it's just a special case of open.
467 (scm_init_filesys): move interning of constants O_CREAT etc.,
468 here (were previously using SCM_CONST_LONG macro).
469 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
471 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
472 include "fports.h" and <stdio.h>
473 (scm_stat, scm_select): don't support FD objects.
475 * error.h: adjust scm_syserror_msg prototype.
476 * error.c (scm_syserror_msg): take an extra argument for errno.
477 Using the global value didn't always work, since it could be
478 reset by procedure calls in the message or args arguments.
480 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
481 I don't understand why the check was there (and what about the
484 * strop.c (scm_string_copy): allow shared substrings to be copied.
486 * unif.h: corresponding change to prototypes.
487 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
488 recognize two new optional arguments: offset and length. Allow
489 the port argument to be an integer (file descriptor, for scsh).
490 Include <unistd.h> for "read" prototype.
492 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
494 * socket.c: don't include filesys.h.
496 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
498 * Makefile.am: add AWK=@AWK@ (?)
500 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
502 Add a rule to generate errnos.c from errnos.
503 * error.c (scm_init_error): include errnos.c.
504 * errnos_cnvt.awk: new file, converts the list of errno codes to
506 * errnos_get.c: new file.
507 * errnos.default: new file, contains errnos to try if they can't
508 be extracted from errno.h.
509 * configure.in: if using GCC, try and extract errno codes from
513 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
515 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
516 * Makefile.am: Made libguile into a libtool library.
517 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
518 Set libtool_libs to indicate that libguile is a libtool library.
519 See guile/ChangeLog for details.
520 * .cvsignore: ignore "*.lo", the libtool library objects.
522 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
524 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
525 use htons in getservbyport argument.
527 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
529 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
530 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
533 * objprop.c (scm_object_property): No need to take the CDR of the
534 value returned by scm_object_properties, since Aug 20 change.
536 * configure.in: When checking for struct linger, #include
537 <sys/types.h> as well as <sys/socket.h>. I've never known
538 <sys/types.h> to cause any portability problems, and Solaris's
539 <sys/socket.h> needs it.
540 * configure: Rebuilt.
542 I think the Sun compiler has chosen a perverse way to interpret
543 ANSI declarations combined with K&R definitions. We'll
544 appease it a little bit. But when it invades France, we fight.
545 * print.c (scm_iprlist): Change 'tlr' argument to an int.
546 * print.h (scm_iprlist): Here too.
547 * numbers.c (scm_divbigdig): Change definition to match
548 declaration in numbers.h.
549 * unif.c (scm_makflo): Change definition to match declaration in
552 * init.c (scm_boot_guile): Don't return the value of
553 scm_boot_guile_1. This function doesn't return a value;
554 scm_boot_guile_1 doesn't return a value (or return at all).
556 * eval.c (unmemocopy): Add a semicolon to appease the Sun
559 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
560 compile. I have a feeling this function is a bad idea anyway ---
561 one should always test for features, not systems.
563 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
564 semicolons. Only pure luck kept this from being noticed earlier.
566 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
568 * socket.c (scm_recvfrom): Added missing semicolon.
570 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
572 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
573 the buffer and start and end positions for scsh networking
576 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
578 * configure.in: Revert previous change to this file; the problem
579 is due to transient automake weirdness.
580 * configure: Rebuilt.
582 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
583 PLUGIN/guile.libs. configure generates the latter from the former.
584 * Makefile.in: Rebuilt.
586 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
587 need this if we install scripts, like guile-snarf.
588 * configure: Rebuilt.
590 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
592 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
594 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
596 * socket.c (scm_addr_vector): fix faulty scm_listify.
598 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
600 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
601 style block comment is no longer considered an error.
603 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
605 * PLUGIN/guile.libs.in: New file.
606 * PLUGIN/guile.libs: Removed from repository.
607 * configure.in: Create PLUGIN/guile.libs from
608 PLUGIN/guile.libs.in. This is for including additonal libraries
609 needed for dynamic linking.
610 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
611 instead of PLUGIN/guile.libs.
613 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
615 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
617 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
618 occurrences of the given element from the list, not just the
619 first. This is how the Emacs Lisp functions behave, how the
620 analogous Common Lisp functions behave, and (I believe) how the
621 older Maclisp functions worked. I realize that this change may
622 break code, but it seemed better to break it before the Guile
625 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
626 Their prototypes were already present in gc.h, but they weren't
628 (scm_init_storage): Initialize scm_protects.
629 * root.c (scm_protects): New element of scm_sys_protects.
631 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
633 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
635 * libguile.h: Added #include "libguile/net_db.h".
637 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
638 30 change. That file is only meant for communication between the
639 configuration process and load.c. If code linked against libguile
640 wants to get at the paths mentioned in libpath.h, it can call
641 functions declared in load.h.
643 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
645 * libguile.h: Removed #include "libguile/fdsocket.h"
647 * net_db.c: Added #include <sys/socket.h>.
649 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
651 * filesys.c (scm_input_waiting_p): use select in preference to
652 FIONREAD, since the latter doesn't detect EOF.
653 Throw error if neither select nor FIONREAD available.
655 * socket.c (scm_connect): take a port, not a fd object.
656 (scm_fill_sockaddr): throw an error if fam is not recognised.
657 (scm_bind): use scm_fill_sockaddr.
658 (scm_listen): take a port, not a fd object.
659 (scm_accept): take and return a port. return #f in the car if
661 (scm_sock_fd_to_port): new procedure.
662 (scm_socket): use scm_sock_fd_to_port.
663 (scm_addr_vector): throw error if unrecognised address type.
664 take an extra argument with the calling procedure name.
665 (scm_getsockname): take a port. return #f if address can't be got.
666 (scm_getpeername): take a port. return #f if address can't be got.
667 (scm_recvfrom): take a port. return #f for address component if can't
669 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
670 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
672 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
674 * throw.c (scm_internal_catch): Make body funcs and handler funcs
675 use separate data pointers, to allow them to be designed
676 independently and reused.
677 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
678 Renamed from catch_body, catch_handler, and uncaught_throw; made
680 (struct scm_catch_body_data): Renamed from catch_body_data; moved
682 (scm_catch): Use the above.
683 (scm_throw): Don't bother printing a message for an uncaught
684 throw; we establish a default handler in init.
685 * throw.h (scm_internal_catch): Prototype updated.
686 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
688 (struct scm_body_thunk_data): New structure, used as data
689 argument to scm_body_thunk.
690 * init.c (struct main_func_closure): New structure, packaging up
691 the data to pass to the user's main function.
692 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
693 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
694 scm_internal_catch to establish a catch-all handler, using
695 scm_handle_by_message. This replaces the special-case code in
697 (invoke_main_func): Body function for scm_internal_catch; invoke
698 the user's main function, using the main_func_closure pointer to
699 decide what to pass it.
700 * root.c (struct cwdr_body_data): Remove handler_proc member.
701 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
702 (cwdr_handler): Removed.
704 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
706 * socket.h (SCM_P): update bind prototype.
707 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
709 (scm_socket): return a port, not a file descriptor object.
710 include "fports.h" and <unistd.h>
711 (scm_bind): take a port, not a file descriptor object.
712 take an extra argument for address args.
714 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
715 INADDR_NONE, INADDR_LOOPBACK.
717 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
719 * init.c: include net_db.h and not fdsocket.h.
720 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
722 * Makefile.am: corresponding changes.
723 * socket.h: renamed from fdsocket.h, fix names.
724 * net_db.h: renamed from socket.h, fix names.
725 * socket.c: renamed from fdsocket.c.
726 remove _sys from procedure names.
727 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
728 add "socket" to features list.
729 * net_db.c: renamed from socket.c.
730 remove _sys from procedure names.
731 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
732 add "net-db" to features list.
733 include "net_db.h". don't include <sys/socket.h> or
736 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
738 * tags.h (scm_tags): Removed comma at end of last enumerator.
740 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
742 Don't use GCC extensions to allocate space for debugging frames.
743 (Here he goes again! Why do we put up with this?!)
744 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
745 an scm_debug_info structure, not an in-line array of them. Add
746 'info' member, to say how many vect elements we've used, for eval
748 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
749 a new variable debug_info_end to mark the end of vect, instead of
750 the address of the 'info' pointer itself.
751 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
752 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
753 (SCM_APPLY): Explicitly allocate space for debug.vect.
754 * debug.c (scm_m_start_stack): Same, for vframe.vect.
755 * stacks.c: Adjusted for new debug frame structure.
756 (RELOC_INFO, RELOC_FRAME): New macros.
757 (stack_depth, read_frames): Use them, and new scm_debug_frame
758 element 'info', instead of magically knowing that eval frames have
759 an info pointer sitting after vect.
760 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
762 (scm_init_stacks): Formatting tweaks.
764 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
766 Give GCC more control flow information, so it can be sure that
767 variables aren't used uninitialized.
768 * error.h (scm_error, scm_syserror, scm_syserror_msg,
769 scm_sysmissing, scm_num_overflow, scm_out_of_range,
770 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
771 scm_misc_error): Tell GCC that these functions never return.
772 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
773 out the field type, call abort if SCM_ASSERT returns, to placate
775 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
776 scm_wta ever returns. We can't handle this case anyway, and this
777 gives the optimizer more information.
778 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
779 scm_wta ever returns.
781 In some cases, the code is fine, but GCC isn't smart enough to
782 figure that out; this usually happens when one variable is only
783 initialized and used when a particular condition holds true, and
784 we know that condition will never change within a given invocation
785 of the function. In this case, we simply initialize the variables
786 to placate the compiler, hopefully to a value which will cause a
787 crash if it is ever actually used.
788 * print.c (scm_iprin1): Initialize mw_pos.
789 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
790 * throw.c (scm_ithrow): Initialize dynpair.
791 * unif.c (scm_uniform_vector_ref): Initialize cra.
792 * struct.c (init_struct): Initialize prot.
793 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
795 * strports.c (scm_eval_0str): Don't return uninitialized garbage
796 if EXPR contains no expressions.
798 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
800 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
801 cause an infinite loop (???). So much for the algebraic
802 equivalency of variable-sized arrays and alloca...
804 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
806 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
807 a SCM boolean, not a C boolean.
809 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
811 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
812 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
813 rules for raising scm_mtrigger. Previously, unfortunate but not
814 unlikely circumstances could result in almost constant invokation
815 of the gc. Now, this situations should be less likely, but they
816 are not prevented completely.
818 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
820 * numbers.c (scm_fuck): Procedure removed; looks like old test
822 * numbers.h: Prototype removed.
824 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
826 * debug.h (scm_debug_frame): Change `vect' member from an in-line
827 array to a pointer, to match my Nov 21 change in eval.c.
829 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
831 * libguile.h: Added #include "libguile/backtrace.h", #include
834 * strings.c (scm_string scm_make_string scm_string_ref
835 scm_string_set_x scm_string_equal_p scm_string_append):
836 Bugfix according to scm patch from Aubrey Jaffer:
837 Corrected long-standing
838 (not (eqv? (integer->char 128)
839 (string-ref (make-string 1 (integer->char 128)) 0)))
840 bug found by John Kozak <jk@noontide.demon.co.uk>.
842 * strports.c, strports.h: Make scm_eval_0str return the value of
843 the last expression evaluated (previously, it returned void).
845 * strports.c, strports.h: New function: scm_read_0str. Does what
848 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
850 * simpos.c (scm_getenv): return #f if string can't be found in the
851 environment instead of throwing an exception, for compatibility
852 with numerous other systems.
854 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
856 * Makefile.am (.c.x): Use guile-snarf.
857 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
859 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
861 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
863 * backtrace.c (scm_display_error_message): Made non-static, and
864 renamed from display_error_message.
865 * backtrace.h (scm_display_error_message): Added extern decl.
866 * throw.c (uncaught_throw): Use it to display the error message.
868 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
870 * inet_aton.c: Use #if 0, not #ifdef 0.
872 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
874 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
875 to convert the returned value.
876 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
879 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
881 Add new interface to catch/throw, usable from C as well as
883 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
884 (scm_internal_catch): New function, replaces...
885 (scm_catch_apply): Deleted.
886 * throw.c (scm_catch_apply): Deleted; replaced with a more general
887 mechanism which is a bit more code, but can be used nicely from C
888 and implement the Scheme semantics as well.
889 (scm_internal_catch): This is the replacement; it's named after
890 the analogous function in Emacs.
891 (scm_catch): Reimplemented in terms of the above.
892 (struct catch_body_data, catch_body, catch_handler): New
893 functions, used by scm_catch.
894 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
895 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
896 support for new cwdr.
898 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
901 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
903 * acconfig.h: Added DYNAMIC_LINKING symbol.
904 * configure.in: Add option and checks for dynamic linking.
905 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
906 dynl.h: New files for dynamic linking support.
907 * Makefile.am (libguile_a_SOURCES):
909 (modinclude_HEADERS): Added "dynl.h".
910 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
912 * init.c (scm_boot_guile_1): Call
913 scm_init_dynamic_linking to initialize dynamic linking support.
915 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
917 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
918 (as we Schemers say). It needs to be global, so that I can tweak
919 it for the proper operation of unexec.
920 (scm_boot_guile_1_live): New variable, see above.
922 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
924 * guile-snarf.sh: Removed.
925 * PLUGIN/guile.libs: Added dependency for -lm.
926 * acinclude.m4: Renamed from aclocal.m4.
927 * PLUGIN/greet: Removed.
928 * Makefile.am, aclocal.m4: New files.
929 * configure.in: Updated for Automake.
931 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
933 * eval.c (scm_definedp): Use top_level_lookup_closure_var
934 and not top_level_lookup_thunk_var.
936 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
938 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
940 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
942 * eval.c (scm_definedp): Incompatibly changed to be a builtin
943 Scheme function, instead of syntax. Single argument is now a
946 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
948 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
949 scm_ra_divide): Properly terminate statements passed as arguments
950 to IVDEP macros. (Thanks to Bernard Urban.)
952 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
953 with non-constant sizes. (Thanks to Bernard Urban.)
955 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
957 It's an "eval closure", not an "eval thunk." A thunk is a
958 function of no arguments.
959 * root.h (struct scm_root_state): Renamed
960 top_level_lookup_closure_var from top_level_lookup_thunk_var.
961 (scm_top_level_lookup_closure_var): Renamed from
962 scm_top_level_lookup_thunk_var.
963 * root.c (mark_root): Uses changed.
964 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
965 * init.c (scm_start_stack): Uses changed.
966 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
967 Change scheme-visible name to *top-level-lookup-closure* from
968 *top-level-lookup-thunk*.
970 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
972 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
973 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
975 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
977 * gc.c (struct scm_heap_seg_data): Doc fixes.
979 * gc.c (scm_gc_sweep): Empty all segments' freelists before
980 sweeping. Then, prepend each segment's free cells to its
981 freelist, rather than wiping out the old value. (Thanks to Marius
984 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
985 scm_check_freelist, scm_debug_newcell): New functions and
986 variables, for debugging freelist problems.
987 * pairs.h (SCM_NEWCELL): New debugging version added.
988 * gc.h (scm_debug_newcell): Added extern declaration, used by
989 debugging version of SCM_NEWCELL.
991 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
993 On some systems <libc.h> conflicts with <unistd.h>, and should not
995 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
996 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
997 * configure.in: Call it.
998 * posix.c, filesys.c: Use its results to decide whether or not to
1000 * configure, scmconfig.h.in: Rebuilt with autoconf and
1003 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1005 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
1006 pointer to the stdio stream before calling scm_setbuf0, so the
1007 latter will be able to retrieve it. I'm surprised this didn't
1008 segfault earlier. (Thanks to Christopher Lee.)
1010 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1012 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
1015 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1017 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
1018 number of stack narrowing specifier pairs. The first specifier in
1019 a pair controls inner border, the second the outer border. A
1020 number means cut that number of frames, a procedure object means
1021 cut until that object is found in operator position in a frame.
1023 * root.c (cwdr): Bugfix.
1025 * read.c: Recording of positions disabled by default.
1027 * procs.c (scm_closure_p): New function.
1029 * posix.c (scm_tmpnam): New function.
1031 * load.c: Added #include "throw.h".
1032 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
1035 * load.c, load.h (scm_read_and_eval_x): New function.
1037 * eval.c: Renamed debug option "deval" to "debug".
1039 (scm_eval_x): `eval!' is no longer accessible from the scheme
1040 level. Motivation: We can't allow operations which introduce
1041 glocs into the scheme level. Guile's type system can't handle
1042 these as data. Use `eval' or `read-and-eval!' as replacement.
1044 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
1045 SCM_CONSP since this is a macro!; Set vframe.prev to
1046 scm_last_debug_frame instead of 0. In this way we can look
1047 "above" the virtual start stack frame if we wish.
1048 (scm_debug_hang): New function: Useful for debugging Guile in
1049 certain tricky situations. Will probably be removed later...
1051 * debug.h: Changed semantics of debug option "backtrace". This
1052 option now only indicates whether we want automatic backtrace at
1055 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1057 * ports.c: #include "filesys.h"
1058 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
1060 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
1061 Motivation: This is system specific code which is related to file
1062 I/O. It also may use select. Added code by Gary Houston to
1063 detect presence of character in stdio buffers.
1065 * libguile.h: #include "libguile/libpath.h"
1067 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
1068 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
1069 SCM_SITE_DIR; Install libpath.h among the other include files.
1071 * load.c, load.h (scm_sys_package_data_dir): New function.
1073 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1075 * stacks.h: Bugfix: Don't use tail-array length field as stack
1076 length field! This screwed GC.
1078 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1080 * _scm.h: Added #ifndef around definition of macros min and max.
1082 * __scm.h: Added hooks for threads to plugin to in ints protection
1083 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
1084 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
1085 the main code in these macros duplicated and spread over multiple
1086 files. Renamed SCM_THREADS_SWITCHING_CODE ->
1087 SCM_THREAD_SWITCHING_CODE.
1089 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
1091 * snarf.h: New file.
1092 * guile-snarf.sh: New file.
1093 * Makefile.in (inner_h_files): Added snarf.h
1094 (ancillary, install, uninstall, distclean): Added actions for
1096 (.c.x): Use guile-snarf.
1097 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
1098 (gen_c_files): Note that these depend on guile-snarf.
1099 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
1100 now in "snarf.h". Added #include "snarf.h" to get them.
1101 * libguile.h: Added #include "snarf.h".
1102 (Patches applied and tweaked by Jim Blandy.)
1104 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1106 * socket.c: Use K&R style declaration for 'close'; the GNU coding
1107 standards suggest against providing prototypes for system
1108 functions. Thanks to Greg Troxel.
1110 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1112 * strports.c (scm_eval_0str): New function.
1113 #include "read.h", to get prototype for scm_read.
1114 * Makefile.in (strports.o): Update dependencies.
1115 * strports.h: New prototype.
1117 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
1118 scheme name from "int?" to "integer?". It seems to do the job.
1119 * numbers.h: Rename prototype too.
1120 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
1123 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
1124 scm_num_eq_p): Rename these according to R4RS conventions: call
1125 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
1126 to making libguile R4RS compliant without ice-9...
1128 * load.c (scm_sys_search_load_path): Search for files under all
1129 extensions listed in the %load-extensions variable. If FILENAME
1130 is absolute, return it unchanged, without searching the load path.
1131 (scm_loc_load_extensions): New variable, pointing to
1132 %load-extensions' value cell.
1133 (scm_init_load): Initialize it, and the value it points to.
1134 (scm_primitive_load_path): Improve error reporting.
1136 * load.c (scm_loc_load_hook): New variable, pointing to value cell
1137 of new Scheme variable %load-hook.
1138 (scm_primitive_load): Apply %load-hook to filename.
1140 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
1142 * configure.in: add tests for figuring out whether buffered data
1143 is available in a FILE structure, which is needed by char-ready.
1145 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
1148 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
1149 exceptions using misc_error instead of syserror. It seems a bit
1150 odd to throw an exception if a string can't be found in the
1151 environment, but it's consistent with open-file, stat etc.
1152 (simpos.h): remove sys_ from getenv.
1154 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
1155 occurs, throw an error instead of returning errno. Return value
1157 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1159 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1161 * filesys.c (scm_stat2scm): derive file type and permissions from
1162 the stat mode and append them to the returned vector.
1163 There isn't much overhead in doing this and it avoids the need to
1164 work with S_IRUSR et al. in Scheme.
1165 Define symbols scm_sym_regular etc.
1166 (scm_init_filesys): don't intern S_IRUSR etc.
1168 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1169 and s_primitive_load_path.
1171 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1173 * error.h: don't declare error symbols. prototype for scm_misc_error.
1175 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1178 * error.c: use SCM_SYMBOL to set up error keys.
1179 scm_misc_error: new procedure.
1181 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1183 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1184 between `#!' and `!#' is ignored.
1185 (skip_scsh_block_comment): New function.
1187 * feature.c (scm_set_program_arguments): New argument, FIRST.
1188 * feature.h: Update prototype.
1189 * init.c (scm_boot_guile_1): Pass new argument to
1190 scm_set_program_arguments.
1192 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1194 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1195 (scm_boot_guile): Call scm_set_program_arguments here, later than
1196 the old initialization.
1198 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1199 initialization procedure.
1200 - Delete in, out, err arguments; there are other perfectly good
1201 ways to override these when desired.
1202 - Delete result argument; this function shouldn't ever return.
1203 - Rename init_func argument to main_func, for less confusion.
1204 - Delete boot_cmd argument; main_func is more general.
1205 -Add 'closure' argument, to help people pass data to main_func
1206 without resorting to global variables.
1207 - Abort if reentered; don't bother returning an error code.
1208 - Call scm_init_standard_ports to set up the default/current
1209 standard ports; no need to pass them to scm_start_stack.
1210 - Remove code to evaluate the boot_cmd, and start the repl; let
1211 the user do something like that in main_func if they want.
1212 - Remove code to package up a return value; main_func can do any
1214 - Call exit (0), instead of returning.
1215 (scm_start_stack): Don't initialize the I/O ports here; that's
1216 weird. Delete in, out, err arguments. Move guts to
1217 scm_init_standard_ports, scm_stdio_to_port.
1218 (scm_init_standard_ports): New function, to set up current and
1219 default standard ports.
1220 (scm_start_stack, scm_restart_stack): Make these static.
1221 * init.h (scm_boot_guile): Adjust declaration.
1222 (scm_start_stack, scm_restart_stack): Remove externally
1223 visible declarations for these.
1224 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1226 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1227 written out several times in scm_start_stack.
1228 * fports.h: New declaration for the above.
1230 * feature.c (scm_set_program_arguments): New function.
1231 * feature.h: New declaration for the above.
1233 * ports.c: Formatting tweak.
1235 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1237 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1238 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1239 for obtaining the address of a car or cdr field. Motivation:
1240 &SCM_CXR make assumptions about the internal structure of the
1243 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1244 Motivation: see SCM_CXRLOC.
1246 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1247 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1248 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1249 Motivation: Safer use. Some other macros are defined in terms of
1250 these operations. If these are defined using the SCM_SETCXR
1251 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1252 to inefficiency and an <e1> with side-effects could potentially
1253 break. Also, these particular operations are heavily utilized in
1254 the garbage collector. In unoptimized code there will be a
1257 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1258 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
1259 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
1260 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
1261 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
1262 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1263 vports.c: Cleaned up use of pairs: Don't make any special
1264 assumptions about the internal structure of selectors and
1265 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1266 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1267 (Among other things, this change makes it easier to build Guile
1268 with certain compilers which have problems with casted lvalues.)
1270 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1272 * stacks.c: Improve selection of relevant stack frames when making
1273 a stack object. Introduce one level of indirection in the stack
1274 object to make it possible to "narrow" to a certain region of the
1275 stack. This facilitates making use of more clever algorithms (not
1276 implemented) for selecting relevant frames and gives a cleaner
1277 design since selection of frames can be done independently of
1278 extraction of frames from the real stack.
1279 (scm_stack_id): Also take #t as argument which means look at
1282 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1283 Turn n_tail into an integer directly representing current number
1284 of frames in stack. Add field tail.
1286 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1288 * debug.c (scm_make_memoized): Made it available at scheme level.
1289 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1290 SCM_NIMP before applying heavier predicates in argument checking.
1291 (scm_local_eval): Also take memoized object as argument.
1293 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1294 aren't created with zero length, but should such a strange
1295 creature suddenly turn up...
1297 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1299 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1300 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1302 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1304 * variable.c (scm_make_variable): Make the name hint optional, as
1306 (anonymous_variable_sym): Renamed from variable_sym. All uses
1309 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1310 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1311 of scm_primitive_load_path was also changed to
1312 "primitive-load-path", from "%try-load-path". Callers changed.
1313 We'd like to respect the convention that a function named
1314 "try-mumble" should behave just like the function called "mumble",
1315 but return #f instead of signalling some error.
1316 * load.h: Rename prototypes.
1318 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1320 * print.c (make_print_state, grow_print_state), print.h: Modified
1321 the print state representation: Don't use a tail array for
1322 recording of circular references. Resizing of the print state
1323 structure invalidates the print state pointer. To avoid passing
1324 around an indirect print state reference to all printing
1325 functions, we instead let the print state reference a resizable
1328 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1330 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1331 Don't crash when passed an improper list terminated by a
1332 non-immediate value.
1334 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1336 Allocate data for structures on an eight-byte boundary, as
1337 required by the tagging system.
1338 * struct.c (alloc_struct): New function.
1339 (scm_make_struct, scm_make_vtable_vtable): Call it.
1340 * struct.h (scm_struct_n_extra_words): Bump to 3.
1341 (scm_struct_i_ptr): New "field".
1342 * gc.c (scm_gc_sweep): When we need to free the data, use the
1343 information stored by alloc_struct to find the beginning of the
1344 block allocated to the structure, so we can free it.
1346 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1348 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1351 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1352 (scm_debug_info): New member: id.
1354 * stacks.c: Stacks are now represented as structs; Stacks have an
1355 id given to them by `start-stack'.
1356 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1358 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1359 Changed stack representation.
1361 * debug.c (scm_procedure_name): Try procedure property `name' for
1362 compiled closures aswell.
1364 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
1366 * eval.c: scm_i_name moved to gsubr.c
1367 (scm_m_define): Record names of all kinds of procedure
1368 objects. (Earlier, only closures were recorded.)
1370 * procprop.h: Added declaration of scm_i_name.
1372 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1373 (scm_make_gsubr): Record names of compiled closures.
1375 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1377 * debug.c, debug.h: Removed obsolete code.
1379 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1380 stacks.c: Renamed regs --> scm_contregs.
1382 * print.c (scm_free_print_state): Cleanup print state before
1383 returning it to pool. It is better to do it here than in
1384 scm_prin1 since scm_prin1 is called often.
1386 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1387 s_set_source_property_x): Check that first argument is a pair or a
1390 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1391 scm_i_line, scm_i_column and scm_i_breakpoint global.
1393 * init.c: Added #include "backtrace.h" and #include "stacks.h".
1394 (scm_boot_guile_1): Added calls to scm_init_backtrace and
1397 * debug.h: Added debug object smob declaration and macro
1400 * configure.in: Build with backtrace.o and stacks.o if debug
1403 * Makefile.in: Added entries for new files: backtrace.c,
1404 backtrace.h, stacks.c and stacks.h.
1406 * symbols.c (scm_sym2ovcell): Fixed documentation.
1408 * _scm.h (min, max): Added.
1410 * async.c: Moved `min' macro to _scm.h.
1412 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1413 SCM_BACKTRACE_INDENT.
1415 * eval.c: Added new debug options `maxdepth' and `indent'.
1417 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
1419 * print.h: Added selector SCM_PRINT_STATE.
1421 * print.c: New functions: scm_make_print_state,
1422 scm_free_print_state.
1424 * print.h: Added declarations for scm_make_print_state,
1425 scm_free_print_state.
1427 * debug.c (scm_m_start_stack): New acro.
1429 * debug.h: Small cleanup.
1431 * init.c (scm_boot_guile_1): Moved scm_init_debug below
1434 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

1456 declare functions with prototypes. (Patch thanks to Marius
1459 More prototype-related changes from Marius Vollmer:
1460 * gdb_interface.h: Wrapped header file in #ifdef/#endif
1461 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
1462 * ports.h (ptobfuns): Added prototypes. This means some casting in
1464 * fports.c: Added casts for initializations, since the functions
1465 are defined to take FILE * as their stream argument, not SCM.
1466 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
1467 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
1468 to `char *str_data' to conform to prototype.
1470 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1472 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
1474 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
1476 * stime.c, stime.h: use SCM_P method.
1478 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1480 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
1481 be given at least two arguments. Insist that lst's last element
1482 be a list, but don't make any requirements of its predecessors.
1484 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1486 * eval.c (scm_nconc2last): Revert last change; there seems to be
1487 other stuff going on here.
1489 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1491 * eval.c (scm_nconc2last): Make sure that each element of lst
1492 (which is a list of argument lists, except for the tail) is a
1493 proper list, i.e., finite and terminated by '().
1495 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1497 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
1500 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
1501 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
1504 * vectors.c (scm_make_vector): Fill vectors with the undefined
1505 value, to help make Guile Scheme code more portable to other
1508 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
1509 * symbols.h, tags.h: Doc fixes.
1511 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
1513 * async.c (scm_take_signal): Doc fixes.
1515 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
1517 * numbers.c (scm_divbigint): When the remainder is zero, we don't
1518 want to subtract it from the modulus; we just want to leave it
1521 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
1523 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
1526 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
1528 * throw.c (scm_catch_apply): Finished implementation of
1531 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
1533 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
1535 (scm_init_filesys): set "i/o-extensions" feature.
1538 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
1540 * Makefile.in (root.o): Correct dependencies.
1542 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
1544 * Makefile.in: Added dependency entry for root.o.
1546 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
1547 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
1549 * init.c (scm_start_stack): Set initial root continuation number
1552 * procs.c: New function: scm_thunk_p.
1554 * procs.h: Added declarations of scm_thunk_p.
1556 * root.c: Renamed `call-with-new-root' -->
1557 `call-with-dynamic-root'.
1558 (cwdr): Removed allocation of new root state. This should be done
1559 separately by use of scm_make_root.
1560 (scm_apply_with_dynamic_root): New function: Does what it
1561 sounds like. Needed when spawning threads.
1563 * root.h: Added member last_debug_frame to root state.
1564 Added #include "libguile/debug.h"
1566 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
1567 arguments. The motivation is that code in root.c needs catch
1568 functionality, and we want to avoid code duplication.
1569 New functions: scm_catch, scm_lazy_catch. These are wrappers for
1570 scm_catch_apply. scm_lazy_catch is intended to introduce catch
1571 handlers that run without popping the stack into the dynwind
1574 * throw.h: Added prototypes for scm_catch_apply and
1577 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1579 * root.h (scm_root, scm_set_root): Decouple thread support details
1580 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
1581 SCM_SET_THREAD_LOCAL_DATA.
1583 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
1584 and tortoise scanning loop.
1586 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
1588 * Makefile.in: Rebuild dependencies.
1590 * libguile.h: #include "libguile/print.h" before "smob.h", since
1591 the latter uses the print_state structure.
1593 * throw.c (scm_ithrow): Use the correct variable when checking to
1594 see if a given element of scm_dynwinds is a valid catch.
1596 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
1597 structure, abort; don't just silently ignore the garbage.
1599 * _scm.h: #include "print.h" here, since it seems to be used just
1601 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
1602 strports.c, unif.h: Don't #include "print.h".
1604 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1606 * feature.h (scm_loc_features): Removed external declaration.
1607 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
1609 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1611 * feature.c (scm_init_feature): Added threads feature (needs to be
1612 initialized here, since features doesn't exist when
1613 scm_init_threads is called).
1615 * libguile.h: Added #include "libguile/../threads/threads.h".
1616 (This is a kludge to get thread support working. This should be
1619 * configure.in, acconfig.h: Added flags for thread support.
1621 * scmsigs.c: Define `signal' to be `pthread_signal' if using
1624 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
1625 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
1628 * _scm.h: Added conditional #include "threads.h"
1630 * __scm.h (SCM_ASYNC_TICK): Added call to macro
1631 SCM_THREADS_SWITCHING_CODE.
1633 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
1634 allocate the basic dynamic root object.
1635 (scm_boot_guile): Added call to scm_init_root.
1637 * root.c, root.h: Added root smob.
1638 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
1639 functions: Implements dynamic roots mostly according to spec in
1640 SCM manual. Main difference is that the second argument is a
1641 throw handler rather than an error "thunk".
1643 * root.h: Added declaration of scm_init_root.
1645 * root.c: Added #include "genio.h", #include "smob.h", #include
1646 "pairs.h", #include "throw.h", #include "dynwind.h", #include
1648 (scm_init_root): Added #include "root.x".
1650 * throw.c: Added #include "stackchk.h"
1651 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
1652 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
1653 can be used in scm_call_with_new_root; Added reenabling of stack
1654 checking when catching a throw.
1656 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
1658 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
1660 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
1661 element is not found, as per R4RS.
1663 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1665 * list.c: Doc fixes throughout.
1667 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1669 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
1670 declare the char * to be const. Avoids a warning in rgx.c.
1672 * ports.h: spelling fix.
1674 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
1677 * load.c (scm_sys_try_load_path): throw an error if file not found
1678 (like it says it in NEWS).
1680 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1682 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
1683 PROPS slot to '(), not #f; it's an empty alist.
1685 * throw.h, throw.c: Use SCM_P instead of #if hair.
1687 Remove special support for uncaught throws; see throw.c for
1689 * throw.c (uncaught_throw): New function.
1690 (scm_ithrow): Call uncaught_throw if we don't find a throw
1691 target; don't mess with scm_bad_throw_vcell.
1692 (scm_bad_throw_vcell): Variable deleted.
1693 (scm_init_throw): Don't initialize it.
1695 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
1698 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1700 * numbers.c (scm_istr2int): If the number is short (as most
1701 numbers are), just call scm_small_istr2int to deal with it.
1702 (scm_small_istr2int): New function, created by un-#ifdefing the
1703 non-bignum version of scm_istr2int and renaming it.
1705 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
1707 * load.c (scm_sys_try_load): don't check whether value returned
1708 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
1709 Change the Scheme name from %try-load to primitive-load.
1711 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
1712 Can avoid passing a message, allowing it to be derived in the
1713 error handler (e.g., if we want to throw to the key both from
1716 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
1718 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
1719 references now have a new appearance which is more compact and
1720 also gives a clue about what the target of the reference is.
1721 By setting parameters in the print state, more fancy printing can
1722 be achieved. This is used by the (not yet commited) backtrace
1725 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
1727 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
1730 * print.c: Added #include "struct.h". Removed function
1733 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
1734 scm_iprin1. Removed prototype for scm_prlist.
1736 * arbiters.c (prinarb),
1737 async.c (print_async),
1738 debug.c (prindebugobj, prinmemoized),
1739 eval.c (prinprom, prinmacro),
1740 filesys.c (scm_fd_print, scm_dir_print),
1742 mallocs.c (prinmalloc),
1743 numbers.c, numbers.h (scm_floprint, scm_bigprint),
1744 smob.h (scm_smobfuns),
1745 srcprop.c (prinsrcprops),
1747 unif.c, unif.h (scm_raprin1, rapr1),
1748 variable.c (prin_var): Changed argument `int writing' to
1749 `scm_print_state *pstate'.
1751 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
1752 that it will be called before scm_init_print.
1754 * print.c (scm_prin1): Print states are now allocated when calling
1755 scm_prin1 and then passed around to all printing functions as an
1756 argument. A cache `print_state_pool' enables reuse of print
1758 (scm_make_print_state): New function.
1759 (scm_iprin1): Adaption to print states.
1760 (scm_iprlist): An initial "hare and tortoise" scan brings down
1761 time complexity to O (depth * N). (Better time complexity will be
1762 achieved when the printing code is completely rewritten.)
1764 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1766 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
1767 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
1768 it gets done whether or not the cache variable has a value.
1770 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
1772 Distinguish #f and ().
1773 * __scm.h: #undef SICP.
1774 * pairs.h (SCM_EOL): Delete this definition, equating it with
1776 * tags.h (SCM_EOL): Give it a new definition here; I think I found
1777 the value it used to have. Doc fixes, too.
1779 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
1781 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
1782 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
1783 Lord's implementation of structs, allowing for tail arrays as
1784 described in the manual. Also fixed some bugs. (Both the interface
1785 and the implementation should be improved.)
1787 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
1789 * print.c, print.h: Closures now print like #<procedure foo (x)>.
1790 People who whish to see the source can do `(print-enable 'source)'.
1791 Removed #ifdef DEBUG_EXTENSIONS.
1793 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1795 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
1796 integer (assuming for now accepting an integer is a good thing).
1798 * error.c, fports.c: replace use of %S in lgh_error args with %s.
1799 %S will be used instead for write'ing arguments.
1801 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
1802 asserts. fix a few other asserts.
1803 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
1804 scm_uniform_vector_ref, scm_array_set_x,
1805 scm_dimensions_to_unform_array): change args in
1806 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
1807 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
1808 scm_substring_fill_x): likewise.
1809 gsubr.c (scm_gsubr_apply): likewise.
1810 eval.c (SCM_APPLY): likewise.
1812 * eval.c (4 places): replace scm_everr with lgh_error or
1815 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
1816 scm_memory_error): new procedures.
1817 scm_everr: deleted. can use scm_wta, dropping first two args.
1818 scm_error: convert NULL subr to SCM_BOOL_F.
1820 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
1823 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
1826 * error.c, error.h: new error keys: scm_arg_type_key,
1827 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
1829 scm_wta: reimplement using lgh_error instead of scm_everr.
1831 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
1833 * gdbint.c: scm_lread now has one more argument.
1835 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
1836 scm_port_\1; Added mutator scm_set_port_filename_x (used when
1837 loading source from non-file ports, which, e. g., happens when
1838 using the Emacs interface).
1840 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
1843 * read.c: Added code for recording of positions of source code
1844 expressions; New functions: recsexpr, scm_lreadrecparen;
1845 _scm_make_srcprops --> scm_make_srcprops
1846 (scm_flush_ws): Removed updating of positions counters. This work
1847 is already done by scm_gen_getc
1849 * read.h: Added prototype for scm_lreadrecparen
1851 * print.c: Added #include "alist.h"
1853 * eval.c: Added #include "hash.h"
1855 * eq.c: Added #include "ramap.h"
1857 * options.c: Documentation fixes.
1859 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
1860 (scm_init_srcprop): Adjusted size of initial source-whash. Name
1861 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
1862 --> scm_make_srcprops
1864 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
1865 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
1866 function calls in the definition of the whash access macros.
1868 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
1870 * init.c (scm_boot_guile): Add level of indirection to
1871 scm_boot_guile_1() to ensure that stack base pointer is properly
1872 initialized. There was no guarantee that variable i was the
1873 highest/lowest variable on stack (i.e. the call frame of
1874 scm_boot_guile was not completely protected from gc).
1876 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
1878 * ports.h (scm_port_table): put back file_name, it will be used to
1879 support debugging. Undo related changes in fports.c, ioext.c,
1882 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1884 * ports.h (scm_port_table): remove file_name member for now, it seems
1886 * fports.c (scm_open_file): don't set file_name in PTAB.
1887 (prinfport): don't use file_name in PTAB.
1888 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
1889 * ports.c (scm_add_to_port_table): don't intialize file_name.
1890 (scm_port_file_name): remove for now.
1891 * gc.c (scm_gc_mark): don't mark PTAB file_name.
1893 * fports.h (scm_mkfile): prototype deleted.
1894 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
1896 * debug.c, unif.c: use scm_out_of_range instead of
1897 wta for range errors (ASSERT still needs work).
1899 * error.c, error.h (scm_out_of_range): new procedure.
1901 * error.c, error.h (scm_out_of_range_key): new key.
1903 * posix.c (scm_sync): #else was missing.
1905 * error.c, error.h: append _key to names scm_num_overflow and
1908 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
1909 of consing an empty list.
1910 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
1911 of macros, saves code and string space.
1912 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
1913 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
1914 lower case. Rename scm_syserror_m to scm_syserror_msg.
1915 error.h: prototypes for new procedures.
1917 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
1919 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
1921 * error.c, error.h: setup scm_num_overflow key.
1923 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
1924 Remove definition of SCM_OVSCM_FLOW.
1926 * fports.c (scm_open_file): use SCM_SYSERROR_M.
1928 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
1929 explicit message and args.
1931 * error.c, error.h, __scm.h: change system_error_sym to
1934 * error.c (system_error_sym): remove leading %% from the Scheme name
1937 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
1939 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1941 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
1942 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
1943 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
1944 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
1945 renamed. (These were introduced by unsupervised name
1948 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1950 * print.c: Added code for detection of circular references during
1951 printing. (init_ref_stack, grow_ref_stack): New functions. Added
1952 a hook for printing of closures (accessible via print options).
1953 This leads to a split of calls to scm_iprin1 into two classes:
1954 elementary print operations (e. g. the code which prints a smob)
1955 still use scm_iprin1 while top level calls (like scm_display) use
1956 scm_prin1. scm_prin1 begins by clearing the data structure used
1957 to record reference information.
1959 * print.h: Added declarations of scm_prin1 and scm_prlist.
1961 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
1963 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
1965 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
1967 * error.c (err_head): scm_iprin1 --> scm_prin1
1969 * debug.c: Adjusted header comment.
1973 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1975 * strerror.c: Doc fix.
1977 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1979 * gdbint.c (gdb_read): Now possible to run during GC.
1980 (unmark_port, remark_port): New functions.
1982 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
1984 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
1985 of allocating a new string object. Also, increase size by
1986 the factor 2 instead of 1.5.
1988 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
1990 * __scm.h (SCM_P): Corrected to run under traditional C.
1992 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
1995 * async.c: Calls to scm_sysintern corrected.
1997 * async.h (scm_async_clock): Redundant declaration removed.
1999 * continuations.c (scm_dynthrow): Redundant declaration removed.
2001 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
2002 Definition typos corrected.
2004 * debug.h: Missing declarations of functions in debug.c added
2007 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2008 Missing declarations to functions in eval.c added.
2010 * filesys.c: Possibly uninitialized variable rv.
2012 * gc.h (scm_object_addr, scm_unhash_name): Missing
2013 declarations of functions defined in gc.c added.
2015 * genio.c: Possible typos str_data -> wstr_data. ???
2017 * genio.c: Possibly unintended shadowing of local variable
2018 `int c' (gotos out of scope of inner `c'). ???
2020 * init.c: Uninitialized `SCM last' may be used.
2022 * ioext.h: (scm_sys_isatty_p): Typo.
2024 * list.h (scm_list_head): Missing prototype for function in
2027 * numbers.c (scm_two_doubles): Changed from extern to static
2028 (is used only within numbers.c).
2030 * numbers.h: Repeated declarations removed.
2032 * ports.h (scm_close_all_ports_except): Declaration for the
2033 function defined in ports.c added.
2035 * posix.h: Missing declarations added.
2037 * procs.h (scm_make_subr_opt): Missing declaration added.
2039 * socket.h (scm_sys_gethost): Missing declaration added.
2041 * socket.h: Redundant declarations removed (they are in fdsocket.h).
2043 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
2044 Missing declarations added.
2046 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
2048 * struct.c: Uninitialized variable `SCM answer' may be used.
2050 * unif.c (l2ra): Declaration prototype.
2052 * unif.c (scm_array_equal_p): Dummy definition removed (it is
2053 defined in ramap.c).
2055 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
2056 Redundant declarations removed (they are in ramap.h).
2058 * variable.h (scm_make_udvariable,
2059 scm_make_undefined_variable): Declaration corrected to
2060 correspond variable.c.
2062 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
2063 Missing declarations added.
2065 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
2067 * Makefile.in (distclean): Don't forget to delete fd.h.
2069 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2071 * fd.h.in, tags.h: Trivial cleanups.
2073 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
2074 marksweep.h just declared functions from gc.c.
2075 * gc.h, libguile.h: Don't #include "marksweep.h".
2076 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2077 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
2078 dependencies updated.
2080 * libguile.h: Don't #include "files.h"; it's been deleted.
2082 * files.c (scm_sys_delete_file): Moved to filesys.c.
2083 File is now empty; deleted.
2085 * filesys.c: scm_sys_delete_file is now here. Remove
2086 #if's; they seem to rely on remnants of an old portability
2087 regimen. If the problems come up again, solve them properly,
2088 using autoconf. Specifically: Don't test M_SYSV, and #define
2089 remove to be unlink if it's #defined; don't use remove just
2090 because HAVE_STDC_HEADERS is #defined.
2091 * filesys.h: Add declarations for scm_sys_delete_file.
2092 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2093 files.o, files.h, files.c, and files.x.
2094 * init.c: Don't #include "files.h", and don't call scm_init_files.
2096 Use SCM_P instead of PROTO; the latter intrudes on the user's
2098 * params.h: Deleted; definition of SCM_P moved to...
2099 * __scm.h: ... here, where it replaces PROTO macro.
2100 * libguile.h, smob.h: Don't #include "params.h".
2101 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
2102 smob.h: Fix prototypes accordingly.
2103 * Makefile.in: Update dependencies.
2104 (inner_h_files): Remove params.h.
2106 * gc.c: #include "gc.h"; every module should include its header,
2107 to let the compiler cross-check the declarations against the
2110 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2111 simpos.h: #include "libguile/__scm.h".
2113 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2115 * init.c: Don't forget to #include smob.h and init.h.
2116 * Makefile.in: Dependencies updated.
2118 * smob.h: Use PROTO instead of #if __STDC__.
2120 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2122 * __scm.h: Doc fixes.
2124 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2125 <angles>; this allows `make depends' to work properly.
2127 * libguile.h: #include smob.h and pairs.h before the others; they
2128 define typedefs used by other headers.
2130 C files should #include only the header files they need, not
2131 libguile.h (which #includes all the header files); the pointless
2132 recompilation was wasting my time.
2133 * Makefile.in (all .o dependency lists): Regenerated.
2134 * libguile.h: Don't try to get a definition for size_t here...
2135 * __scm.h: Do it here.
2136 * _scm.h: Since this is the internal libguile header, put things
2137 here that all (or a majority) of the libguile files will want.
2138 Don't #include <libguile.h> here; that generates dependencies on
2139 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2140 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2141 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

2238 * weaks.c: Get "weaks.h".
2240 * stackchk.h: #include "libguile/debug.h",
2242 * print.h, read.h: #include "options.h", since everyone who uses
2243 either of these files will need that.
2245 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2246 anyone who uses this file will need them to define the smob
2247 printing functions. Also, get markers.h, since people will need
2248 to #define the mark functions.
2250 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2251 * ports.h: ... to here.
2253 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2254 don't rely on archaic C default type rules.
2256 * fports.h: #include "libguile/ports.h", since you need that in
2257 order to parse this.
2259 * genio.h: #include "libguile/print.h", because you need that to
2260 parse this; don't bother #including "ports.h", since print.h gets
2263 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2265 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2266 this; it's now a reference to an element of *scm_root.
2268 * debug.h: Don't #include "options.h"; the compiler won't be able
2269 to find that once the headers are installed; instead, #include
2270 "libguile/options.h".
2271 * gc.h: Same, with marksweep.h.
2272 * mbstrings.h: Same, with symbols.h.
2273 * scmhob.h: Same, with _scm.h.
2274 * smob.h: Same, with params.h.
2276 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2277 C files; there's no need for this, and it forces recompilations
2280 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2282 * error.c (scm_error): declare scm_error_callback.
2284 * error.h: prototype for scm_error_callback.
2286 * __scm.h: define lgh_error.
2287 (SCM_SYSERROR): redefine using lgh_error.
2289 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2291 * error.c (scm_error): new procedure.
2293 * error.h: prototype for scm_error.
2295 * Makefile.in (install): install scmconfig.h from the current
2296 directory, not $(srcdir).
2298 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2300 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2301 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2302 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

2308 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2309 vports.h, weaks.h: #include "libguile/__scm.h", not
2310 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2311 dependencies are within libguile properly.
2313 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2315 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2316 when scmconfig.h doesn't exist.
2318 * load.c (scm_sys_try_load): Correct spelling.
2320 * feature.c (scm_loc_features): Make this static.
2322 * Makefile.in (libpath.h): Omit trailing slash from path. We
2323 shouldn't require it of users, so why put it here?
2325 Move code to initialize and search %load-path from ice-9 to C
2326 code, so we can use the load-path to find the ice-9 boot code;
2327 this makes it easier to run Guile without installing it. See
2328 corresponding changes in guile/Makefile.in.
2329 * feature.c: Move stuff concerned with the load path to load.c.
2330 (scm_compiled_library_path): Deleted.
2331 Don't #include libpath.h here.
2332 * feature.h: Don't mention scm_compiled_library_path.
2333 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2334 <sys/stat.h>, and <unistd.h> (if present).
2335 (R_OK): #define if the system hasn't deigned to.
2336 (scm_loc_load_path): New variable.
2337 (scm_init_load_path, scm_sys_search_load_path,
2338 scm_sys_try_load_path): New functions.
2339 (scm_init_load): Initialize scm_loc_load_path to point to the
2340 value cell of the Scheme %load-path variable.
2341 * load.h: Add declarations for scm_sys_search_load_path,
2342 scm_sys_try_load_path.
2343 * init.c: Call scm_init_load_path.
2344 * Makefile.in (feature.o, load.o): Dependencies updated.
2346 * load.c, load.h: Rewrite using PROTO macro.
2348 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2350 * gc.c (scm_cellp): New function: C predicate to determine if an
2351 SCM value can be regarded as a pointer to a cell on the heap.
2353 * gc.h: Added declaration of scm_cellp.
2355 * gdb_interface.h: New file: The GDB interface header from the GDB
2358 * gdbint.c: New file: GDB interface.
2360 * gdbint.h: New file: GDB interface.
2362 * libguile.h: Added #include <libguile/gdbint.h>.
2364 * init.c (scm_boot_guile): Added scm_init_gdbint.
2366 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2367 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2368 found if object files and source are kept separate).
2370 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2372 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2374 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2376 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2377 TK_SRC_DIR; they're not relevant any more.
2379 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2380 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2382 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2384 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2385 search path, so we can find the <libguile/MUMBLE.h> headers.
2387 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2389 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2390 implicit in the .c.o rule.
2391 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2394 Put the library path in a header file, instead of passing it on
2395 the command line in every compilation.
2396 * Makefile.in (libpath.h): New target.
2397 (feature.o): Depend on libpath.h.
2398 (clean): Delete libpath.h.
2399 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2400 * feature.c: ... #include "libpath.h" here.
2401 * .cvsignore: Ignore libpath.h.
2403 Don't install the unwashed masses of Guile header files in the
2404 main #include path; put most of them in a subdirectory called
2405 'libguile'. This avoids naming conflicts between Guile header
2406 files and system header files (of which there were a few).
2407 * Makefile.in (pkgincludedir): Deleted.
2408 (innerincludedir): New variable; this and $(includedir) are enough.
2409 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
2410 (installed_h_files): Divide this up. Now this variable lists
2411 those header files which should go into $(includedir) (i.e. appear
2412 directly in the #include path), and ...
2413 (inner_h_files): ... this new variable says which files appear in
2414 a subdirectory, and are referred to as <libguile/mumble.h>.
2415 (h_files): List them both.
2416 (install): Create innerincludedir, not pkgincludedir. Put
2417 the installed_h_files and inner_h_files in their proper places.
2418 (uninstall): Corresponding changes.
2419 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2420 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2421 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
2422 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
2423 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
2424 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2425 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2426 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2427 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2428 vports.h, weaks.h: Find __scm.h in its new location.
2429 * __scm.h: Find scmconfig.h and tags.h in their new locations
2430 (they're both "inner" files).
2432 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
2434 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
2436 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2438 * posix.c: Doc fixes.
2440 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
2442 * socket.c: Don't include a prototype for inet_aton; just use a
2443 K&R style declaration, to avoid warnings but minimize the chance
2444 of conflicts with the system.
2446 On NextStep, <utime.h> doesn't define struct utime, unless we
2447 #define _POSIX_SOURCE before #including it.
2448 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
2449 * acconfig.h: New comment text for above CPP symbol.
2450 * configure.in: Call it.
2451 * posix.c: #define _POSIX_SOURCE if it seems necessary.
2453 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
2455 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
2456 testing for __EMX__.
2458 * posix.c: #include <libc.h>, if it exists.
2460 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
2461 don't even know if the latter exists.
2463 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
2464 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
2465 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
2467 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
2469 (scm_init_posix): Use them when initializing the Scheme constants
2472 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2474 * Makefile.in (libdir, includedir, bindir): Use the
2475 autoconf-supplied values, instead of deriving them ourselves.
2476 (pkgincludedir, datadir, pkgdatadir): New variables.
2477 (install, uninstall): Put the header files in a special
2478 subdirectory, not in the main search path.
2480 * Makefile.in (ALL_CFLAGS): Provide the proper value for
2481 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
2483 * Makefile.in (IMPLPATH): Deleted; never used.
2485 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
2486 on the Tcl/Tk source any more.
2487 (INCLUDE_CFLAGS): Remove references to the above.
2489 * Makefile.in (version.o): Corrected dependencies.
2491 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
2493 * libguile.h: #include "version.h"
2495 * init.c (scm_boot_guile): Call scm_init_version.
2496 * gscm.c (gscm_run_scm): Call scm_init_version.
2498 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
2499 GUILE_VERSION): AC_DEFINE these.
2500 (acconfig.h): #undef the above symbols.
2502 * Makefile.in (libobjs): Add version.o.
2503 (installed_h_files): Add version.h.
2504 (c_files): Add version.c.
2505 (gen_c_files): Add version.x.
2506 (version.o): New rule.
2507 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
2508 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
2509 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
2510 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,

2516 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
2517 weaks.o): Add version.h to dependency lists.
2518 (markers.o): Remove duplicate rule.
2520 * version.h: New file.
2522 * version.c: New file.
2524 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2526 * symbols.c (scm_strhash): scm_downcase is now a function, not an
2527 array; use it appropriately. Since GCC is quite happy to
2528 subscript functions, it never warned us about this; we should use
2529 -Wpointer-arith in the future. I guess we never tested
2532 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2534 * socket.c: Doc and copyright fixes.
2536 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2538 * debug.c: Fixed and improved gdb support.
2540 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2542 * socket.c: Added declaration of inet_aton to avoid compiler
2543 warning. (Hope this solution is correct.)
2545 * stime.c: Added declaration of ftime. (This is missing in
2548 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
2550 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2552 * Makefile.in (c_files): add strerror.c.
2554 * strerror.c: new file from Emacs' sysdep.c.
2555 maybe configure should also check for sys_errlist.
2557 * configure.in (AC_REPLACE_FUNCS): add strerror.
2559 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2561 * debug.c (scm_init_debug): Added initialization for
2562 scm_evaluator_traps.
2564 * debug.h, debug.c: Various name changes.
2565 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
2566 "debug-options-interface". See commentary in options.c.
2568 * options.h, options.c: Options now have documentation strings.
2569 Also added a long explanatory commentary.
2571 * eval.c, print.h, print.c, read.h, read.c: Modifications to
2574 * gscm.c, init.c, root.c, throw.c: Bug fixes:
2575 last_debug_info_frame is now updated in all cases.
2577 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
2580 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2582 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
2583 Added option STACK_CHECKING.
2585 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
2587 * Makefile.in: Added {debug,options,srcprop}.{h,c}
2589 * __scm.h: Removed symbols for debugging support.
2591 * acconfig.h: Added symbols for debugging support.
2593 * configure.in: Added user option for debugging support.
2594 --enable-debug will include the debugging code into libguile.a.
2596 * continuations.c (scm_make_cont): Enlarged the #if 0 around
2597 scm_relocate_chunk_to_heap.
2599 * debug.c: New file: low-level debugging support. It also
2600 includes support for debugging with gdb. (The extensions to gdb
2601 are written by Per Bothner at Cygnus.)
2603 * debug.h: New file: low-level debugging support.
2605 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
2606 argument pairs. Extensive modifications to the debugging
2607 evaluator. Added "SECTION:" commentaries to clarify what happens
2608 when, during double compilation. Renamed EVALIMP --> EVALIM.
2609 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
2610 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
2611 the beginning of the file. New procedure: scm_unmemocopy.
2612 Added some global state variables needed by the debugging
2613 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
2614 check_entry, check_apply, check_exit, debug_options and
2615 evaluator_traps. New acro: undefine.
2617 * eval.h: Renamed EVAL --> XEVAL.
2619 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
2620 --> scm_make_weak_key_hash_table.
2622 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
2623 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
2625 * libguile.h: Conditionally include debug.h
2627 * objprop.c (scm_object_properties, scm_set_object_properties_x):
2628 scm_object_properties shouldn't return handle. `handle' now gets
2629 initialized in scm_set_object_properties_x. scm_object_properties
2630 doesn't any longer create an entry in scm_object_whash.
2632 * options.c: New file: handling of run time options.
2634 * options.h: New file: handling of run time options.
2636 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
2638 * print.c: New procedure: scm_print_options
2640 * print.h: Defines for print options.
2642 * read.c: New procedure: scm_read_options
2644 * read.h: Defines for reader options.
2646 * root.h: Added scm_source_whash among scm_sys_protects.
2648 * srcprop.c: New file: source properties.
2650 * srcprop.h: New file: source properties.
2652 * throw.c (jbsmob): Jump buffers are now correctly allocated.
2653 (Bug found by A. Green.)
2655 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2657 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2659 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
2661 * libguile.h: #include "objprop.h"; I guess this was forgotten.
2663 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
2664 and should be called by the final client.
2666 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
2668 * gc.h: Use the PROTO macro when declaring functions.
2669 * gc.c: Use the PROTO macro when declaring static functions.
2670 Remove the CPP hair around function definitions.
2672 * gc.c (scm_init_storage): Initialize scm_asyncs.
2674 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
2675 preprocessor symbol; "__scm.h" is where it might get #defined.
2676 * __scm.h: Similar: #include <scmconfig.h> before testing
2679 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
2681 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
2683 * init.c (scm_boot_guile): Add init_func argument; call
2684 (*init_func) instead of calling scm_appinit; it's ucky to
2685 hard-code names for the user's procedures.
2686 * init.h (scm_boot_guile): Adjust declaration.
2688 * __scm.h (PROTO): New macro, for declaring functions with
2691 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
2692 eliminate all the __STDC__ conditionals.
2693 (scm_boot_guile): Add declaration.
2694 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
2695 Remove __STDC__ conditionals around function definitions; the
2696 declarations in init.h will provide the same information, more
2699 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
2700 complain about it in the error message; the error message is
2701 adequate without that note, and there's nothing the user can do
2704 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
2706 * Makefile.in (ancillary): Drop def.sed.
2708 * posix.c (scm_init_posix): Use numeric values, rather than
2709 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
2710 F_OK. The symbols aren't available on some systems, and I'm
2711 pretty sure their values are fixed by common widespread practice.
2712 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
2714 More functions unavailable on some systems.
2715 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
2716 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
2718 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2719 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
2720 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
2721 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
2722 stub that signals an error as the #else.
2724 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
2726 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
2728 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
2730 * unif.c: include ramap.h.
2732 * read.c (endif): case_insensative_p renamed case_insensitive_p.
2734 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
2736 * ports.c: include sys/ioctl.h.
2738 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
2740 * configure.in: check for sys/ioctl.h.
2742 * ports.c: include <malloc.h> not "malloc.h".
2744 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2746 * fports.c: remove ttyname and tmpnam declarations.
2748 * posix.c: fewer ttyname declarations.
2750 * fports.c: include <string.h> not "string.h".
2752 * init.c, ioext.c: include string.h and unistd.h.
2754 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2756 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
2757 genio.c, simpos.c, vports.c: include string.h.
2759 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
2761 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
2763 (scm_addr_buffer_size): change type from scm_sizet to int.
2764 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
2765 from scm_sizet to int.
2767 * error.c: include unistd.h.
2769 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
2772 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
2774 * __scm.hd, def.sed: deleted.
2776 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
2778 Changes for NeXT, suggested by Robert Brown.
2779 * configure.in: Call AC_TYPE_MODE_T.
2780 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
2781 NeXT. Put header file list in alphabetical order.
2782 * configure, scmconfig.h.in: Regenerated.
2783 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
2785 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
2788 * acconfig.h: New file, providing documentation for the CPP
2789 symbols defined in configure.in
2790 * acconfig-1.5.h: Removed; superceded by the above.
2792 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
2794 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
2796 * fports.c (scm_open_file): don't return #f, throw error.
2798 * ioext.c (fileno): renamed from %fileno.
2799 (soft-fileno): deleted.
2801 * ports.c (scm_port_revealed): don't need to check for -1 from
2803 (scm_set_port_revealed_x): return unspecified, not #f.
2805 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
2807 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
2809 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
2811 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
2813 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2815 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
2816 This is necessary on Ultrix, and doesn't hurt portability.
2818 * Makefile.in (dist-dir): New target, implementing a new dist system.
2819 (installed_h_files): Put in alphabetical order.
2820 Remove duplicate entries for markers.h and unif.h.
2821 (c_files): Remove duplicate entries for markers.c.
2822 (ancillary): Renamed from anillery; all uses changed. Remove
2823 PLUGIN; it's a directory, and needs special treatment in dist-dir.
2824 Remove all the ../doc/* files; doc/Makefile.in handles that.
2826 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
2828 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
2829 every if must have an else, or else the whole command has a
2830 non-zero exit code whenever the if's condition is false.
2832 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
2834 * posix.c: include string.h.
2836 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2838 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
2841 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
2842 Remove leading % from scheme names.
2843 Do not return error values, call SCM_SYSERROR or similar.
2845 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
2847 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
2849 * struct.c (scm_init_struct): new file.
2851 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
2853 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
2854 (scm_list_head): added list-head for rapidly chopping argument
2855 lists off of longer lists (and similar).
2857 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
2859 * objprop.c (scm_object_property): assq the cdr of the whash
2860 handle for obj, not the handle itself.
2862 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
2864 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
2865 weak hash tables last of all marking to avoid an obscure gc bug.
2866 WARNING: circular lists stored in a weak hash table will hose us.
2868 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
2870 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
2871 new functions similar to scm_substring_move_left_x and
2872 scm_substring_move_right_x.
2874 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
2876 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
2879 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
2881 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
2883 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
2885 * strports.c (scm_strprint_obj): convenience function. C for
2886 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
2888 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
2889 removed to a separate library
2891 * init.c (scm_boot_guile): copied from guile-tcl.c.
2892 Initialization specific to tcl interpreters removed.
2894 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
2896 * ports.c (scm_ports_prehistory): size malloced here doesn't
2897 matter so long as it is non-0 (got rid of "* 4").
2899 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
2901 * gscm.h: gscm_mkarray eliminated (presumably was not being used
2902 since its definition was bogus).

2908 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
2910 * ports.c: removed functions relating to the mapping between ports
2911 and descriptors. (That stuff is unix-specific and should be collected

2919 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
2920 handled correctly (SCM_FREEP was applied to them) -- test for

2976 * ports.c (scm_add_to_port_table): Added fields

3089 initialization to fix a race condition.
3091 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

3115 set the multi_byte flag correctly in symbols. This is wrong.
3116 intern_obbary_soft and msymbolize should take an extra parameter.

3118 The weird symbol syntax is also a bit bogus (emacs doesn't quite
