1 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
4 wan't defined. Don't include fd.h.
6 * Previously fd.h was regenerated whenever configure was run,
7 forcing a couple of files to be recompiled.
9 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
10 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
11 Check for _fileno as well as _file.
13 * ioext.c: don't fd.h.
14 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
17 * Change the stratigy for getting information about errno
18 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
19 generating lists of symbols during the build process, which will
20 not always work, include comprehensive lists in the distribution.
21 To help keep the lists up to date, the "check_signals" and
22 "check_errnos" make targets can be used.
24 * configure.in: don't check for a command to extract errno codes.
25 * Makefile.am: update file lists, remove errnos.list and errnos.c
26 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
28 (CLEANFILES): remove errnos.c and errnos.list, add
29 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
30 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
31 * errnos.default: deleted.
32 * cpp_signal.c: new file.
33 * cpp_errno.c: renamed from errnos_get.c.
34 * cpp_err_symbols, cpp_sig_symbols: new files.
35 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
36 * error.c (scm_init_error): #include cpp_err_symbols instead of
38 * posix.c (scm_init_posix): don't intern signal symbols. #include
41 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
43 * strop.c (scm_i_index): allow the lower bound to be equal to the
44 length of the string, so a null string doesn't always give an error.
46 * posix.h: new prototypes.
47 * posix.c (scm_status_exit_val, scm_status_term_sig,
48 scm_status_stop_sig): new functions, as in scsh. They break down
49 process status values as returned by waitpid.
51 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
53 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
54 configure doesn't know about it.
56 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
58 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
60 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
61 which defines C variables with global linkage.
63 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
65 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
68 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
70 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
71 has time to check why this doesn't work well with continuations.
73 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
75 * Fix shell syntax error; some shells won't tolerate
76 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
78 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
80 * posix.c (scm_uname): throw an error if uname fails instead
83 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
85 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
88 * async.c (scm_ints_disabled): definition moved from error.c.
90 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
92 * acconfig.h: Removed PACKAGE.
94 * scmconfig.h.in: Regenerated.
96 * snarf.h: g++ says it's non-portable not to specify the first
97 argument in a varargs declaration. I introduced the first
98 argument by using preprocessor conditionals.
100 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
102 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
103 (scm_freopen): use RO string macros for filename and modes.
104 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
106 * posix.c (scm_getgrgid): simplify conversion of name to C string.
107 (scm_mknod): use RO string macros for path.
109 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
110 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
112 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
113 use SCM_ROSTRINGP and SCM_ROCHARS.
115 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
117 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
120 * ramap.c (scm_ra_matchp, scm_ra_matchp, scm_array_fill_int, racp,
121 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
122 support for byte vectors.
124 * print.c (scm_iprin1): Limit number of vector elements printed
125 according to pstate->length.
127 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
129 * backtrace.c (scm_display_error_message): don't segv if message
132 * error.h: prototype for scm_error_scm.
134 * error.c (scm_error_scm): new procedure, reimplements scm-error
135 in C and uses scm_error.
137 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
139 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
140 pointer to the Scheme variable read-hash-procedures and intern it
141 in scm_init_read. Modify scm_read_hash_extend and
142 scm_get_hash_procedure to use the pointer.
144 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
146 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
147 (SCM_KEYWORD_STYLE): defined.
149 * read.c (scm_read_opts): add a keywords option. This isn't a
150 boolean option, in case someone wants to add support for DSSSL
152 Setup scm_keyword_prefix symbol.
153 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
155 * I've left keyword support disabled by default, since it doesn't
156 seem to break the module system and it gives R4RS standard behaviour.
157 It can be reactivated with (read-set! keywords 'prefix).
159 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
161 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
162 before constructing arbiter.
164 * eval.c (scm_m_define): Bugfix: Check that the object is a
165 closure before setting the procedure property!
167 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
169 * ports.c: Removed `ungetc-char-ready?'.
171 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
173 * read.c (scm_init_read): intitialise scm_read_hash_procedures
174 (idea from Mikael: make it a pair so scm_permanent object only
176 (scm_read_hash_extend): don't call scm_permanent_object.
177 (ideas from Mikael): if chr is already in the list, replace its
178 procedure instead of appending it again. If proc is #f, remove
180 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
182 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
184 * gdbint.c (gdb_read): update scm_lreadr usage.
186 * load.h: update prototypes.
188 * load.c (scm_primitive_load, scm_read_and_eval_x,
189 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
191 * read.h: add prototype for scm_read_hash_extend. Change args for
194 * read.c (scm_read_hash_procedures): new variable.
195 (scm_read_hash_extend): new procedure.
196 (scm_get_hash_procedure): new procedure.
197 * (scm_lreadr): use scm_get_hash_procedure instead of an argument
198 for extended # processing.
199 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
200 scm_read_token): remove case_i, sharp arguments. Change callers.
202 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
204 * read.h (SCM_N_READ_OPTIONS): increase to 3.
205 (SCM_CASE_INSENSITIVE_P): define.
207 * read.c: add case-insensitive option to scm_read_opts.
208 * (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
209 to determine whether to convert symbol case.
210 (default_case_i): definition removed.
211 * read.c (scm_read_token): if case_i, downcase ic before doing
214 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
216 * configure.in: Added configuration option `guile-debug'.
217 Configure with --enable-guile-debug if you want a bunch of extra
218 functions used for debugging when developing Guile.
220 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
222 * procs.c (make-cclo): New undocumented debugging procedure: Make
223 compiled closure with internal procedure PROC and length LENGTH.
224 Only compiled if GUILE_DEBUG is defined.
226 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
228 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
230 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
232 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
233 with 3 or more args internally to the evaluator.
235 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
237 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
238 with 3 or more args internally to the evaluator. This is mainly
239 because we don't want to pass entry and exit points of the
240 debug support twice, but it also seems to increase the speed of
241 the evaluator for such calls (e. g. (+ 1 2 3)).
243 * * backtrace.c (scm_display_application): New procedure:
244 display-application; Set fancy printing parameters individually
245 for different types of display (backtrace, error, application).
246 (These should of course be customizable!)
248 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
249 clear the CHECK-flags.
251 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
253 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
255 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
257 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
258 from pairs with a GLOC in the car.
260 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
261 otherwise `symbol-hash' will behave badly.
262 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
263 we get segmentation fault!
265 * * symbols.c: Added #include "weaks.h". New functions:
266 `builtin-bindings' and `builtin-weak-bindings'. (These will be
267 moved to an extraneous library when we split libguile.)
269 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
271 * filesys.c (scm_stat): stat now takes fport arguments too as
272 documented in the manual.
274 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
276 * debug.c (scm_single_step): Bugfix: Call continuation with
277 scm_call_continuation instead of throwing to it.
279 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
281 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
282 argument wasn't declared to be optional.
284 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
286 * stime.c (scm_init_stime): Add feature "current-time".
288 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
290 * throw.h: prototype for scm_exit_status.
291 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
292 args to derive an exit status. Allows (quit) to work from a
294 (scm_exit_status): new function.
297 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
299 * eval.c (scm_deval): Removed some old code.
300 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
302 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
305 * symbols.c (msymbolize): Bugfix: Must initialize property list to
308 * procs.c: Introduce the existent C function scm_thunk_p at the
309 Scheme level as well.
311 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
313 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
314 used from C to easily lookup the value of a symbol in the current
317 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
319 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
320 scm_init_unif in this file. This will also fix a previous problem
323 * configure.in: Added AM_MAINTAINER_MODE
325 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
327 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
330 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
332 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
333 source files that are not always included in libguile but should
334 have their dependencies calculated by automake. This variable is
335 recognized by automake, no further magic is needed.
336 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
337 to deal exclusively with *.lo files, as it seems. The *.o files
338 are built automatically when the corresponding *.lo file gets
341 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
343 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
346 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
348 * unif.c (scm_array_set_x): minor change to argument error checking.
350 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
352 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
353 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
354 They should only be included in the library at configure.in's
356 (libguile_la_LDADD): Include the appropriate .lo files here.
357 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
358 so we know when to build them (and their .lo bretheren).
359 * configure.in (LIBLOBJS): New substituted variable. We let
360 configure decide which .o files to include in LIBOBJS, and then
361 put the corresponding list of .lo files in LIBLOBJS. The latter
362 is what we pass to libtool.
363 * Makefile.in, configure: regenerated.
365 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
367 * symbols.c (scm_sysintern0): New function. Contains the core of
368 old scm_sysintern but doesn't take a second value argument.
369 (scm_sysintern): Now uses scm_sysintern0.
370 (scm_sysintern_no_module_lookup): Renamed to
371 scm_sysintern0_no_module_lookup and doesn't take a second value
374 * symbols.h (scm_sysintern0: Added declaration.
376 * options.c (scm_init_opts): Use scm_sysintern0 instead of
377 scm_sysintern when interning option keys. Otherwise we risk
378 destroying the values of already interned variables.
380 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
381 scheme-level boolean (use SCM_NFALSEP).
383 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
385 (scm_backtrace): New function. (C version of old function from
386 boot-9.scm) Motivation: Make it possible to display backtraces
387 without depending on boot-9.scm. (I'm uncertain if this
388 motivation is good enough...)
390 * root.h (scm_root_state): Add member the_last_stack_var.
391 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
393 * root.c (mark_root): Mark scm_the_last_stack_var.
395 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
398 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
400 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
401 1. mark_lazy_catch didn't mark the smob.
402 2. Both functions above have standard variants:
403 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
404 free_lazy_catch --> scm_free0.
406 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
408 * throw.c (scm_internal_lazy_catch): New function.
409 (scm_lazy_catch): Rewritten to use it.
410 (scm_ithrow): Handle the new lazy catch representation.
411 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
412 that doesn't have a jmpbuf is a lazy catch clause.
413 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
414 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
415 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
417 (scm_init_throw): Register the new lazy-catch smob type.
418 * throw.h (scm_internal_lazy_catch): decl for new function.
420 * throw.c (scm_internal_catch): Doc fixes.
422 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
423 configure.in. Including this might cause problems if applications
424 that link against libguile include their own copies of alloca, but
425 if they're using autoconf, they should be adding libguile to LIBS
426 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
427 the copy in libguile, and things will be okay. (I think.)
429 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
431 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
433 strop.h: move prototypes too.
435 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
437 * posix.c (scm_init_posix): don't intern EINTR since it's now done
440 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
441 etc. I deleted them from filesys.c long ago, but didn't
442 notice they were here too (although ineffective since
443 sys/stat.h wasn't included).
445 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
447 * eval.c: Don't define alloca in GCC case. gcc will automatically
448 use __builtin_alloca if appropriate.
450 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
452 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
453 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
454 that values of automatic variables are preserved. See comments
455 for safe_setjmp for details.
457 Change from Thomas Morgan:
458 * variable.c: Include eq.h.
459 (var_equal): New function.
460 (variable_smob): Use var_equal as the discriminator for variables.
462 * throw.c (s_throw): Remove extraneous declaration.
464 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
465 * eval.c: Add necessary CPP cruft to support that.
466 * configure, Makefile.in, scmconfig.h.in: regenerated.
468 Change from Thomas Morgan:
469 * procprop.c (scm_procedure_properties): Convert the Scheme
470 boolean returned by scm_procedure_p into a C boolean before using
471 it as a condition for SCM_ASSERT.
472 (scm_procedure_property): Likewise.
474 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
475 indications of Unixness.
478 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
480 * * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
482 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
484 * read.c (scm_lreadr): use scm_misc_error to improve one of the
485 "unknown # object" error messages.
487 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
488 (scm_i_index) and declare it static. Add a 'direction' argument
489 to indicate what way the search should go.
490 (scm_i_index): throw out-of-range error instead of wrong-type-arg
492 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
493 strop.h: remove scm_i_index, scm_i_rindex prototypes.
495 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
497 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
499 * * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
500 to avoid clash with various scsh forks.
502 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
504 The following two changes (ramap.c, throw.c) are motivated by the
505 apparent unportability of forward declarations of static arrays of
506 the form `static foo bar[];'.
508 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
509 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
511 * throw.c (scm_throw): Moved above scm_ithrow.
513 * options.h: Removed the extern declarations of scm_yes_sym and
514 scm_no_sym since these are static.
516 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
518 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
520 * Makefile.am: remove AWK=@AWK@.
521 Add a rule for generating errnos.list.
522 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
524 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
525 don't extract errnos, just set a variable (avoids the
526 need to recompile error.c just because configure is run.)
528 * unif.h: update prototypes.
529 * unif.c (scm_uniform_array_read,write): change the offset and
530 length arguments to start and end, for consistency.
532 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
534 * ioext.h: update prototypes.
535 * * ioext.c (scm_read_delimited_x): replaces scm_read_line and
536 scm_read_line_x, it's a more general procedure using an
537 interface from scsh. read-line and read-line! are now defined
539 * Note that the new read-line trims the terminator
540 by default, previously it was appended to the returned string. An
541 optional argument specifies how to process the terminator (scsh
542 compatible). For the old behaviour: (read-line port 'concat).
543 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
544 returns a pair, but is converted to multiple values if the scsh
547 socket.h: update prototypes.
548 * socket.c (scm_recvfrom): for consistency with other procedures,
549 take start and end as separate optional arguments.
550 * (scm_recv, scm_recvfrom): don't allow the second argument
551 to be a size, only a buffer. Change the scheme names to
552 recv! and recvfrom!. Don't return the buffer.
554 * ioext.h, posix.h: move prototypes too.
555 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
556 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
557 "read.h" and "unif.h".
558 * ioext.c: include "chars.h"
560 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
562 * dynl.c: The dynamic linking and module registration functions
563 are now defined even when dynamic linking is not available for the
564 host system. Some of their functionality can be done without
565 dynamic linking; when it's really needed, they throw errors.
567 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
569 * configure.in: Only define DYNAMIC_LINKING when one of the system
570 dependent functions is detected.
571 * dynl.c (scm_dynamic_func): New function to get the address of a
572 function in a dynamic object.
573 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
574 produced by scm_dynamic_func as the thing to call.
576 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
578 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
579 (scm_register_module_xxx, scm_registered_modules,
580 scm_clear_registered_modules): New functions.
582 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
584 * symbols.c (scm_sysintern): Renamed to
585 scm_sysintern_no_module_lookup.
586 (scm_sysintern): New function to take the place of the old
587 scm_sysintern. It uses the current toplevel lookup closure to give
588 the symbol its value. This is a temporary hack to put packages
589 like gtcltk into their own module.
590 (scm_can_use_top_level_lookup_closure_var): New variable to tell
591 us whether `scm_top_level_lookup_closure_var' has been initialized
593 * eval.c (scm_init_eval): Set it.
595 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
597 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
598 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
600 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
602 * (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
603 scm_sys_dup): deleted: FD capability will be added to other
605 * Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
606 scm_fd_free, fd_smob, scm_intern_fd.
607 * (scm_open): renamed from scm_sys_open. Return a port instead of
608 an FD object. Make the mode argument optional.
609 * (scm_sys_create): deleted, it's just a special case of open.
610 (scm_init_filesys): move interning of constants O_CREAT etc.,
611 here (were previously using SCM_CONST_LONG macro).
612 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
614 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
615 include "fports.h" and <stdio.h>
616 (scm_stat, scm_select): don't support FD objects.
618 * error.h: adjust scm_syserror_msg prototype.
619 * error.c (scm_syserror_msg): take an extra argument for errno.
620 Using the global value didn't always work, since it could be
621 reset by procedure calls in the message or args arguments.
623 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
624 I don't understand why the check was there (and what about the
627 * strop.c (scm_string_copy): allow shared substrings to be copied.
629 * unif.h: corresponding change to prototypes.
630 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
631 recognize two new optional arguments: offset and length. Allow
632 the port argument to be an integer (file descriptor, for scsh).
633 Include <unistd.h> for "read" prototype.
635 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
637 * socket.c: don't include filesys.h.
639 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
641 * Makefile.am: add AWK=@AWK@ (?)
643 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
645 Add a rule to generate errnos.c from errnos.
646 * error.c (scm_init_error): include errnos.c.
647 * errnos_cnvt.awk: new file, converts the list of errno codes to
649 * errnos_get.c: new file.
650 * errnos.default: new file, contains errnos to try if they can't
651 be extracted from errno.h.
652 * configure.in: if using GCC, try and extract errno codes from
656 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
658 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
659 * Makefile.am: Made libguile into a libtool library.
660 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
661 Set libtool_libs to indicate that libguile is a libtool library.
662 See guile/ChangeLog for details.
663 * .cvsignore: ignore "*.lo", the libtool library objects.
665 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
667 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
668 use htons in getservbyport argument.
670 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
672 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
673 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
676 * objprop.c (scm_object_property): No need to take the CDR of the
677 value returned by scm_object_properties, since Aug 20 change.
679 * configure.in: When checking for struct linger, #include
680 <sys/types.h> as well as <sys/socket.h>. I've never known
681 <sys/types.h> to cause any portability problems, and Solaris's
682 <sys/socket.h> needs it.
683 * configure: Rebuilt.
685 I think the Sun compiler has chosen a perverse way to interpret
686 ANSI declarations combined with K&R definitions. We'll
687 appease it a little bit. But when it invades France, we fight.
688 * print.c (scm_iprlist): Change 'tlr' argument to an int.
689 * print.h (scm_iprlist): Here too.
690 * numbers.c (scm_divbigdig): Change definition to match
691 declaration in numbers.h.
692 * unif.c (scm_makflo): Change definition to match declaration in
695 * init.c (scm_boot_guile): Don't return the value of
696 scm_boot_guile_1. This function doesn't return a value;
697 scm_boot_guile_1 doesn't return a value (or return at all).
699 * eval.c (unmemocopy): Add a semicolon to appease the Sun
702 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
703 compile. I have a feeling this function is a bad idea anyway ---
704 one should always test for features, not systems.
706 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
707 semicolons. Only pure luck kept this from being noticed earlier.
709 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
711 * socket.c (scm_recvfrom): Added missing semicolon.
713 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
715 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
716 the buffer and start and end positions for scsh networking
719 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
721 * configure.in: Revert previous change to this file; the problem
722 is due to transient automake weirdness.
723 * configure: Rebuilt.
725 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
726 PLUGIN/guile.libs. configure generates the latter from the former.
727 * Makefile.in: Rebuilt.
729 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
730 need this if we install scripts, like guile-snarf.
731 * configure: Rebuilt.
733 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
735 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
737 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
739 * socket.c (scm_addr_vector): fix faulty scm_listify.
741 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
743 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
744 style block comment is no longer considered an error.
746 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
748 * PLUGIN/guile.libs.in: New file.
749 * PLUGIN/guile.libs: Removed from repository.
750 * configure.in: Create PLUGIN/guile.libs from
751 PLUGIN/guile.libs.in. This is for including additonal libraries
752 needed for dynamic linking.
753 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
754 instead of PLUGIN/guile.libs.
756 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
758 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
760 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
761 occurrences of the given element from the list, not just the
762 first. This is how the Emacs Lisp functions behave, how the
763 analogous Common Lisp functions behave, and (I believe) how the
764 older Maclisp functions worked. I realize that this change may
765 break code, but it seemed better to break it before the Guile
768 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
769 Their prototypes were already present in gc.h, but they weren't
771 (scm_init_storage): Initialize scm_protects.
772 * root.c (scm_protects): New element of scm_sys_protects.
774 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
776 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
778 * libguile.h: Added #include "libguile/net_db.h".
780 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
781 30 change. That file is only meant for communication between the
782 configuration process and load.c. If code linked against libguile
783 wants to get at the paths mentioned in libpath.h, it can call
784 functions declared in load.h.
786 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
788 * libguile.h: Removed #include "libguile/fdsocket.h"
790 * net_db.c: Added #include <sys/socket.h>.
792 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
794 * filesys.c (scm_input_waiting_p): use select in preference to
795 FIONREAD, since the latter doesn't detect EOF.
796 Throw error if neither select nor FIONREAD available.
798 * socket.c (scm_connect): take a port, not a fd object.
799 (scm_fill_sockaddr): throw an error if fam is not recognised.
800 (scm_bind): use scm_fill_sockaddr.
801 (scm_listen): take a port, not a fd object.
802 (scm_accept): take and return a port. return #f in the car if
804 (scm_sock_fd_to_port): new procedure.
805 (scm_socket): use scm_sock_fd_to_port.
806 (scm_addr_vector): throw error if unrecognised address type.
807 take an extra argument with the calling procedure name.
808 (scm_getsockname): take a port. return #f if address can't be got.
809 (scm_getpeername): take a port. return #f if address can't be got.
810 (scm_recvfrom): take a port. return #f for address component if can't
812 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
813 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
815 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
817 * throw.c (scm_internal_catch): Make body funcs and handler funcs
818 use separate data pointers, to allow them to be designed
819 independently and reused.
820 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
821 Renamed from catch_body, catch_handler, and uncaught_throw; made
823 (struct scm_catch_body_data): Renamed from catch_body_data; moved
825 (scm_catch): Use the above.
826 (scm_throw): Don't bother printing a message for an uncaught
827 throw; we establish a default handler in init.
828 * throw.h (scm_internal_catch): Prototype updated.
829 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
831 (struct scm_body_thunk_data): New structure, used as data
832 argument to scm_body_thunk.
833 * init.c (struct main_func_closure): New structure, packaging up
834 the data to pass to the user's main function.
835 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
836 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
837 scm_internal_catch to establish a catch-all handler, using
838 scm_handle_by_message. This replaces the special-case code in
840 (invoke_main_func): Body function for scm_internal_catch; invoke
841 the user's main function, using the main_func_closure pointer to
842 decide what to pass it.
843 * root.c (struct cwdr_body_data): Remove handler_proc member.
844 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
845 (cwdr_handler): Removed.
847 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
849 * socket.h (SCM_P): update bind prototype.
850 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
852 (scm_socket): return a port, not a file descriptor object.
853 include "fports.h" and <unistd.h>
854 (scm_bind): take a port, not a file descriptor object.
855 take an extra argument for address args.
857 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
858 INADDR_NONE, INADDR_LOOPBACK.
860 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
862 * init.c: include net_db.h and not fdsocket.h.
863 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
865 * Makefile.am: corresponding changes.
866 * socket.h: renamed from fdsocket.h, fix names.
867 * net_db.h: renamed from socket.h, fix names.
868 * socket.c: renamed from fdsocket.c.
869 remove _sys from procedure names.
870 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
871 add "socket" to features list.
872 * net_db.c: renamed from socket.c.
873 remove _sys from procedure names.
874 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
875 add "net-db" to features list.
876 include "net_db.h". don't include <sys/socket.h> or
879 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
881 * tags.h (scm_tags): Removed comma at end of last enumerator.
883 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
885 Don't use GCC extensions to allocate space for debugging frames.
886 (Here he goes again! Why do we put up with this?!)
887 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
888 an scm_debug_info structure, not an in-line array of them. Add
889 'info' member, to say how many vect elements we've used, for eval
891 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
892 a new variable debug_info_end to mark the end of vect, instead of
893 the address of the 'info' pointer itself.
894 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
895 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
896 (SCM_APPLY): Explicitly allocate space for debug.vect.
897 * debug.c (scm_m_start_stack): Same, for vframe.vect.
898 * stacks.c: Adjusted for new debug frame structure.
899 (RELOC_INFO, RELOC_FRAME): New macros.
900 (stack_depth, read_frames): Use them, and new scm_debug_frame
901 element 'info', instead of magically knowing that eval frames have
902 an info pointer sitting after vect.
903 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
905 (scm_init_stacks): Formatting tweaks.
907 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
909 Give GCC more control flow information, so it can be sure that
910 variables aren't used uninitialized.
911 * error.h (scm_error, scm_syserror, scm_syserror_msg,
912 scm_sysmissing, scm_num_overflow, scm_out_of_range,
913 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
914 scm_misc_error): Tell GCC that these functions never return.
915 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
916 out the field type, call abort if SCM_ASSERT returns, to placate
918 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
919 scm_wta ever returns. We can't handle this case anyway, and this
920 gives the optimizer more information.
921 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
922 scm_wta ever returns.
924 In some cases, the code is fine, but GCC isn't smart enough to
925 figure that out; this usually happens when one variable is only
926 initialized and used when a particular condition holds true, and
927 we know that condition will never change within a given invocation
928 of the function. In this case, we simply initialize the variables
929 to placate the compiler, hopefully to a value which will cause a
930 crash if it is ever actually used.
931 * print.c (scm_iprin1): Initialize mw_pos.
932 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
933 * throw.c (scm_ithrow): Initialize dynpair.
934 * unif.c (scm_uniform_vector_ref): Initialize cra.
935 * struct.c (init_struct): Initialize prot.
936 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
938 * strports.c (scm_eval_0str): Don't return uninitialized garbage
939 if EXPR contains no expressions.
941 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
943 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
944 cause an infinite loop (???). So much for the algebraic
945 equivalency of variable-sized arrays and alloca...
947 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
949 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
950 a SCM boolean, not a C boolean.
952 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
954 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
955 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
956 rules for raising scm_mtrigger. Previously, unfortunate but not
957 unlikely circumstances could result in almost constant invokation
958 of the gc. Now, this situations should be less likely, but they
959 are not prevented completely.
961 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
963 * numbers.c (scm_fuck): Procedure removed; looks like old test
965 * numbers.h: Prototype removed.
967 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
969 * debug.h (scm_debug_frame): Change `vect' member from an in-line
970 array to a pointer, to match my Nov 21 change in eval.c.
972 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
974 * libguile.h: Added #include "libguile/backtrace.h", #include
977 * strings.c (scm_string scm_make_string scm_string_ref
978 scm_string_set_x scm_string_equal_p scm_string_append):
979 Bugfix according to scm patch from Aubrey Jaffer:
980 Corrected long-standing
981 (not (eqv? (integer->char 128)
982 (string-ref (make-string 1 (integer->char 128)) 0)))
983 bug found by John Kozak <jk@noontide.demon.co.uk>.
985 * strports.c, strports.h: Make scm_eval_0str return the value of
986 the last expression evaluated (previously, it returned void).
988 * strports.c, strports.h: New function: scm_read_0str. Does what
991 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
993 * simpos.c (scm_getenv): return #f if string can't be found in the
994 environment instead of throwing an exception, for compatibility
995 with numerous other systems.
997 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
999 * Makefile.am (.c.x): Use guile-snarf.
1000 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
1002 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
1004 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1006 * backtrace.c (scm_display_error_message): Made non-static, and
1007 renamed from display_error_message.
1008 * backtrace.h (scm_display_error_message): Added extern decl.
1009 * throw.c (uncaught_throw): Use it to display the error message.
1011 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
1013 * inet_aton.c: Use #if 0, not #ifdef 0.
1015 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
1017 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
1018 to convert the returned value.
1019 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
1020 the offset argument.
1022 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1024 Add new interface to catch/throw, usable from C as well as
1026 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
1027 (scm_internal_catch): New function, replaces...
1028 (scm_catch_apply): Deleted.
1029 * throw.c (scm_catch_apply): Deleted; replaced with a more general
1030 mechanism which is a bit more code, but can be used nicely from C
1031 and implement the Scheme semantics as well.
1032 (scm_internal_catch): This is the replacement; it's named after
1033 the analogous function in Emacs.
1034 (scm_catch): Reimplemented in terms of the above.
1035 (struct catch_body_data, catch_body, catch_handler): New
1036 functions, used by scm_catch.
1037 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
1038 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
1039 support for new cwdr.
1041 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
1044 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
1046 * acconfig.h: Added DYNAMIC_LINKING symbol.
1047 * configure.in: Add option and checks for dynamic linking.
1048 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
1049 dynl.h: New files for dynamic linking support.
1050 * Makefile.am (libguile_a_SOURCES):
1052 (modinclude_HEADERS): Added "dynl.h".
1053 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
1055 * init.c (scm_boot_guile_1): Call
1056 scm_init_dynamic_linking to initialize dynamic linking support.
1058 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
1060 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
1061 (as we Schemers say). It needs to be global, so that I can tweak
1062 it for the proper operation of unexec.
1063 (scm_boot_guile_1_live): New variable, see above.
1065 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
1067 * guile-snarf.sh: Removed.
1068 * PLUGIN/guile.libs: Added dependency for -lm.
1069 * acinclude.m4: Renamed from aclocal.m4.
1070 * PLUGIN/greet: Removed.
1071 * Makefile.am, aclocal.m4: New files.
1072 * configure.in: Updated for Automake.
1074 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
1076 * eval.c (scm_definedp): Use top_level_lookup_closure_var
1077 and not top_level_lookup_thunk_var.
1079 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
1081 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
1083 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
1085 * eval.c (scm_definedp): Incompatibly changed to be a builtin
1086 Scheme function, instead of syntax. Single argument is now a
1089 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1091 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
1092 scm_ra_divide): Properly terminate statements passed as arguments
1093 to IVDEP macros. (Thanks to Bernard Urban.)
1095 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
1096 with non-constant sizes. (Thanks to Bernard Urban.)
1098 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1100 It's an "eval closure", not an "eval thunk." A thunk is a
1101 function of no arguments.
1102 * root.h (struct scm_root_state): Renamed
1103 top_level_lookup_closure_var from top_level_lookup_thunk_var.
1104 (scm_top_level_lookup_closure_var): Renamed from
1105 scm_top_level_lookup_thunk_var.
1106 * root.c (mark_root): Uses changed.
1107 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
1108 * init.c (scm_start_stack): Uses changed.
1109 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
1110 Change scheme-visible name to *top-level-lookup-closure* from
1111 *top-level-lookup-thunk*.
1113 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
1115 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
1116 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
1118 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
1120 * gc.c (struct scm_heap_seg_data): Doc fixes.
1122 * gc.c (scm_gc_sweep): Empty all segments' freelists before
1123 sweeping. Then, prepend each segment's free cells to its
1124 freelist, rather than wiping out the old value. (Thanks to Marius
1127 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
1128 scm_check_freelist, scm_debug_newcell): New functions and
1129 variables, for debugging freelist problems.
1130 * pairs.h (SCM_NEWCELL): New debugging version added.
1131 * gc.h (scm_debug_newcell): Added extern declaration, used by
1132 debugging version of SCM_NEWCELL.
1134 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1136 On some systems <libc.h> conflicts with <unistd.h>, and should not
1137 be #included at all.
1138 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
1139 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
1140 * configure.in: Call it.
1141 * posix.c, filesys.c: Use its results to decide whether or not to
1143 * configure, scmconfig.h.in: Rebuilt with autoconf and
1146 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1148 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
1149 pointer to the stdio stream before calling scm_setbuf0, so the
1150 latter will be able to retrieve it. I'm surprised this didn't
1151 segfault earlier. (Thanks to Christopher Lee.)
1153 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1155 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
1158 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1160 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
1161 number of stack narrowing specifier pairs. The first specifier in
1162 a pair controls inner border, the second the outer border. A
1163 number means cut that number of frames, a procedure object means
1164 cut until that object is found in operator position in a frame.
1166 * root.c (cwdr): Bugfix.
1168 * read.c: Recording of positions disabled by default.
1170 * procs.c (scm_closure_p): New function.
1172 * posix.c (scm_tmpnam): New function.
1174 * load.c: Added #include "throw.h".
1175 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
1178 * load.c, load.h (scm_read_and_eval_x): New function.
1180 * eval.c: Renamed debug option "deval" to "debug".
1182 (scm_eval_x): `eval!' is no longer accessible from the scheme
1183 level. Motivation: We can't allow operations which introduce
1184 glocs into the scheme level. Guile's type system can't handle
1185 these as data. Use `eval' or `read-and-eval!' as replacement.
1187 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
1188 SCM_CONSP since this is a macro!; Set vframe.prev to
1189 scm_last_debug_frame instead of 0. In this way we can look
1190 "above" the virtual start stack frame if we wish.
1191 (scm_debug_hang): New function: Useful for debugging Guile in
1192 certain tricky situations. Will probably be removed later...
1194 * debug.h: Changed semantics of debug option "backtrace". This
1195 option now only indicates whether we want automatic backtrace at
1198 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1200 * ports.c: #include "filesys.h"
1201 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
1203 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
1204 Motivation: This is system specific code which is related to file
1205 I/O. It also may use select. Added code by Gary Houston to
1206 detect presence of character in stdio buffers.
1208 * libguile.h: #include "libguile/libpath.h"
1210 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
1211 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
1212 SCM_SITE_DIR; Install libpath.h among the other include files.
1214 * load.c, load.h (scm_sys_package_data_dir): New function.
1216 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1218 * stacks.h: Bugfix: Don't use tail-array length field as stack
1219 length field! This screwed GC.
1221 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1223 * _scm.h: Added #ifndef around definition of macros min and max.
1225 * __scm.h: Added hooks for threads to plugin to in ints protection
1226 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
1227 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
1228 the main code in these macros duplicated and spread over multiple
1229 files. Renamed SCM_THREADS_SWITCHING_CODE ->
1230 SCM_THREAD_SWITCHING_CODE.
1232 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
1234 * snarf.h: New file.
1235 * guile-snarf.sh: New file.
1236 * Makefile.in (inner_h_files): Added snarf.h
1237 (ancillary, install, uninstall, distclean): Added actions for
1239 (.c.x): Use guile-snarf.
1240 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
1241 (gen_c_files): Note that these depend on guile-snarf.
1242 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
1243 now in "snarf.h". Added #include "snarf.h" to get them.
1244 * libguile.h: Added #include "snarf.h".
1245 (Patches applied and tweaked by Jim Blandy.)
1247 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1249 * socket.c: Use K&R style declaration for 'close'; the GNU coding
1250 standards suggest against providing prototypes for system
1251 functions. Thanks to Greg Troxel.
1253 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1255 * strports.c (scm_eval_0str): New function.
1256 #include "read.h", to get prototype for scm_read.
1257 * Makefile.in (strports.o): Update dependencies.
1258 * strports.h: New prototype.
1260 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
1261 scheme name from "int?" to "integer?". It seems to do the job.
1262 * numbers.h: Rename prototype too.
1263 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
1266 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
1267 scm_num_eq_p): Rename these according to R4RS conventions: call
1268 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
1269 to making libguile R4RS compliant without ice-9...
1271 * load.c (scm_sys_search_load_path): Search for files under all
1272 extensions listed in the %load-extensions variable. If FILENAME
1273 is absolute, return it unchanged, without searching the load path.
1274 (scm_loc_load_extensions): New variable, pointing to
1275 %load-extensions' value cell.
1276 (scm_init_load): Initialize it, and the value it points to.
1277 (scm_primitive_load_path): Improve error reporting.
1279 * load.c (scm_loc_load_hook): New variable, pointing to value cell
1280 of new Scheme variable %load-hook.
1281 (scm_primitive_load): Apply %load-hook to filename.
1283 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
1285 * configure.in: add tests for figuring out whether buffered data
1286 is available in a FILE structure, which is needed by char-ready.
1288 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
1291 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
1292 exceptions using misc_error instead of syserror. It seems a bit
1293 odd to throw an exception if a string can't be found in the
1294 environment, but it's consistent with open-file, stat etc.
1295 (simpos.h): remove sys_ from getenv.
1297 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
1298 occurs, throw an error instead of returning errno. Return value
1300 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1302 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1304 * filesys.c (scm_stat2scm): derive file type and permissions from
1305 the stat mode and append them to the returned vector.
1306 There isn't much overhead in doing this and it avoids the need to
1307 work with S_IRUSR et al. in Scheme.
1308 Define symbols scm_sym_regular etc.
1309 (scm_init_filesys): don't intern S_IRUSR etc.
1311 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1312 and s_primitive_load_path.
1314 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1316 * error.h: don't declare error symbols. prototype for scm_misc_error.
1318 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1321 * error.c: use SCM_SYMBOL to set up error keys.
1322 scm_misc_error: new procedure.
1324 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1326 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1327 between `#!' and `!#' is ignored.
1328 (skip_scsh_block_comment): New function.
1330 * feature.c (scm_set_program_arguments): New argument, FIRST.
1331 * feature.h: Update prototype.
1332 * init.c (scm_boot_guile_1): Pass new argument to
1333 scm_set_program_arguments.
1335 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1337 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1338 (scm_boot_guile): Call scm_set_program_arguments here, later than
1339 the old initialization.
1341 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1342 initialization procedure.
1343 - Delete in, out, err arguments; there are other perfectly good
1344 ways to override these when desired.
1345 - Delete result argument; this function shouldn't ever return.
1346 - Rename init_func argument to main_func, for less confusion.
1347 - Delete boot_cmd argument; main_func is more general.
1348 -Add 'closure' argument, to help people pass data to main_func
1349 without resorting to global variables.
1350 - Abort if reentered; don't bother returning an error code.
1351 - Call scm_init_standard_ports to set up the default/current
1352 standard ports; no need to pass them to scm_start_stack.
1353 - Remove code to evaluate the boot_cmd, and start the repl; let
1354 the user do something like that in main_func if they want.
1355 - Remove code to package up a return value; main_func can do any
1357 - Call exit (0), instead of returning.
1358 (scm_start_stack): Don't initialize the I/O ports here; that's
1359 weird. Delete in, out, err arguments. Move guts to
1360 scm_init_standard_ports, scm_stdio_to_port.
1361 (scm_init_standard_ports): New function, to set up current and
1362 default standard ports.
1363 (scm_start_stack, scm_restart_stack): Make these static.
1364 * init.h (scm_boot_guile): Adjust declaration.
1365 (scm_start_stack, scm_restart_stack): Remove externally
1366 visible declarations for these.
1367 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1369 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1370 written out several times in scm_start_stack.
1371 * fports.h: New declaration for the above.
1373 * feature.c (scm_set_program_arguments): New function.
1374 * feature.h: New declaration for the above.
1376 * ports.c: Formatting tweak.
1378 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1380 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1381 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1382 for obtaining the address of a car or cdr field. Motivation:
1383 &SCM_CXR make assumptions about the internal structure of the
1386 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1387 Motivation: see SCM_CXRLOC.
1389 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1390 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1391 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1392 Motivation: Safer use. Some other macros are defined in terms of
1393 these operations. If these are defined using the SCM_SETCXR
1394 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1395 to inefficiency and an <e1> with side-effects could potentially
1396 break. Also, these particular operations are heavily utilized in
1397 the garbage collector. In unoptimized code there will be a
1400 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1401 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
1402 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
1403 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
1404 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
1405 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1406 vports.c: Cleaned up use of pairs: Don't make any special
1407 assumptions about the internal structure of selectors and
1408 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1409 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1410 (Among other things, this change makes it easier to build Guile
1411 with certain compilers which have problems with casted lvalues.)
1413 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1415 * stacks.c: Improve selection of relevant stack frames when making
1416 a stack object. Introduce one level of indirection in the stack
1417 object to make it possible to "narrow" to a certain region of the
1418 stack. This facilitates making use of more clever algorithms (not
1419 implemented) for selecting relevant frames and gives a cleaner
1420 design since selection of frames can be done independently of
1421 extraction of frames from the real stack.
1422 (scm_stack_id): Also take #t as argument which means look at
1425 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1426 Turn n_tail into an integer directly representing current number
1427 of frames in stack. Add field tail.
1429 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1431 * debug.c (scm_make_memoized): Made it available at scheme level.
1432 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1433 SCM_NIMP before applying heavier predicates in argument checking.
1434 (scm_local_eval): Also take memoized object as argument.
1436 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1437 aren't created with zero length, but should such a strange
1438 creature suddenly turn up...
1440 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1442 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1443 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1445 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1447 * variable.c (scm_make_variable): Make the name hint optional, as
1449 (anonymous_variable_sym): Renamed from variable_sym. All uses
1452 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1453 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1454 of scm_primitive_load_path was also changed to
1455 "primitive-load-path", from "%try-load-path". Callers changed.
1456 We'd like to respect the convention that a function named
1457 "try-mumble" should behave just like the function called "mumble",
1458 but return #f instead of signalling some error.
1459 * load.h: Rename prototypes.
1461 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1463 * print.c (make_print_state, grow_print_state), print.h: Modified
1464 the print state representation: Don't use a tail array for
1465 recording of circular references. Resizing of the print state
1466 structure invalidates the print state pointer. To avoid passing
1467 around an indirect print state reference to all printing
1468 functions, we instead let the print state reference a resizable
1471 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1473 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1474 Don't crash when passed an improper list terminated by a
1475 non-immediate value.
1477 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1479 Allocate data for structures on an eight-byte boundary, as
1480 required by the tagging system.
1481 * struct.c (alloc_struct): New function.
1482 (scm_make_struct, scm_make_vtable_vtable): Call it.
1483 * struct.h (scm_struct_n_extra_words): Bump to 3.
1484 (scm_struct_i_ptr): New "field".
1485 * gc.c (scm_gc_sweep): When we need to free the data, use the
1486 information stored by alloc_struct to find the beginning of the
1487 block allocated to the structure, so we can free it.
1489 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1491 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1494 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1495 (scm_debug_info): New member: id.
1497 * stacks.c: Stacks are now represented as structs; Stacks have an
1498 id given to them by `start-stack'.
1499 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1501 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1502 Changed stack representation.
1504 * debug.c (scm_procedure_name): Try procedure property `name' for
1505 compiled closures aswell.

1511 objects. (Earlier, only closures were recorded.)
1513 * procprop.h: Added declaration of scm_i_name.
1515 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1516 (scm_make_gsubr): Record names of compiled closures.
1518 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1520 * debug.c, debug.h: Removed obsolete code.
1522 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1523 stacks.c: Renamed regs --> scm_contregs.
1525 * print.c (scm_free_print_state): Cleanup print state before
1526 returning it to pool. It is better to do it here than in
1527 scm_prin1 since scm_prin1 is called often.
1529 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1530 s_set_source_property_x): Check that first argument is a pair or a
1533 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1534 scm_i_line, scm_i_column and scm_i_breakpoint global.
1536 * init.c: Added #include "backtrace.h" and #include "stacks.h".

1547 backtrace.h, stacks.c and stacks.h.
1549 * symbols.c (scm_sym2ovcell): Fixed documentation.
1551 * _scm.h (min, max): Added.
1553 * async.c: Moved `min' macro to _scm.h.
1555 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1556 SCM_BACKTRACE_INDENT.
1558 * eval.c: Added new debug options `maxdepth' and `indent'.

1567 * print.h: Added declarations for scm_make_print_state,
1568 scm_free_print_state.
1570 * debug.c (scm_m_start_stack): New acro.
1572 * debug.h: Small cleanup.
1574 * init.c (scm_boot_guile_1): Moved scm_init_debug below

1597 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
1598 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
1599 declare functions with prototypes. (Patch thanks to Marius
1602 More prototype-related changes from Marius Vollmer:
1603 * gdb_interface.h: Wrapped header file in #ifdef/#endif
1604 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
1605 * ports.h (ptobfuns): Added prototypes. This means some casting in
1607 * fports.c: Added casts for initializations, since the functions
1608 are defined to take FILE * as their stream argument, not SCM.
1609 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
1610 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
1611 to `char *str_data' to conform to prototype.
1613 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1615 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
1617 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
1619 * stime.c, stime.h: use SCM_P method.
1621 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1623 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
1624 be given at least two arguments. Insist that lst's last element
1625 be a list, but don't make any requirements of its predecessors.
1627 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1629 * eval.c (scm_nconc2last): Revert last change; there seems to be
1630 other stuff going on here.
1632 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1634 * eval.c (scm_nconc2last): Make sure that each element of lst
1635 (which is a list of argument lists, except for the tail) is a
1636 proper list, i.e., finite and terminated by '().
1638 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1640 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
1643 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
1644 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
1647 * vectors.c (scm_make_vector): Fill vectors with the undefined
1648 value, to help make Guile Scheme code more portable to other
1651 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
1652 * symbols.h, tags.h: Doc fixes.
1654 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
1656 * async.c (scm_take_signal): Doc fixes.
1658 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
1660 * numbers.c (scm_divbigint): When the remainder is zero, we don't
1661 want to subtract it from the modulus; we just want to leave it
1664 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
1666 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
1669 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
1671 * throw.c (scm_catch_apply): Finished implementation of
1674 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
1676 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
1678 (scm_init_filesys): set "i/o-extensions" feature.
1681 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
1683 * Makefile.in (root.o): Correct dependencies.
1685 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
1687 * Makefile.in: Added dependency entry for root.o.
1689 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
1690 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
1692 * init.c (scm_start_stack): Set initial root continuation number
1695 * procs.c: New function: scm_thunk_p.
1697 * procs.h: Added declarations of scm_thunk_p.
1699 * root.c: Renamed `call-with-new-root' -->
1700 `call-with-dynamic-root'.
1701 (cwdr): Removed allocation of new root state. This should be done
1702 separately by use of scm_make_root.
1703 (scm_apply_with_dynamic_root): New function: Does what it
1704 sounds like. Needed when spawning threads.
1706 * root.h: Added member last_debug_frame to root state.
1707 Added #include "libguile/debug.h"
1709 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
1710 arguments. The motivation is that code in root.c needs catch
1711 functionality, and we want to avoid code duplication.
1712 New functions: scm_catch, scm_lazy_catch. These are wrappers for
1713 scm_catch_apply. scm_lazy_catch is intended to introduce catch
1714 handlers that run without popping the stack into the dynwind
1717 * throw.h: Added prototypes for scm_catch_apply and
1720 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1722 * root.h (scm_root, scm_set_root): Decouple thread support details
1723 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
1724 SCM_SET_THREAD_LOCAL_DATA.
1726 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
1727 and tortoise scanning loop.
1729 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
1731 * Makefile.in: Rebuild dependencies.
1733 * libguile.h: #include "libguile/print.h" before "smob.h", since
1734 the latter uses the print_state structure.
1736 * throw.c (scm_ithrow): Use the correct variable when checking to
1737 see if a given element of scm_dynwinds is a valid catch.
1739 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
1740 structure, abort; don't just silently ignore the garbage.
1742 * _scm.h: #include "print.h" here, since it seems to be used just
1744 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
1745 strports.c, unif.h: Don't #include "print.h".
1747 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1749 * feature.h (scm_loc_features): Removed external declaration.
1750 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
1752 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1754 * feature.c (scm_init_feature): Added threads feature (needs to be
1755 initialized here, since features doesn't exist when
1756 scm_init_threads is called).
1758 * libguile.h: Added #include "libguile/../threads/threads.h".
1759 (This is a kludge to get thread support working. This should be
1762 * configure.in, acconfig.h: Added flags for thread support.
1764 * scmsigs.c: Define `signal' to be `pthread_signal' if using
1767 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
1768 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
1771 * _scm.h: Added conditional #include "threads.h"
1773 * __scm.h (SCM_ASYNC_TICK): Added call to macro
1774 SCM_THREADS_SWITCHING_CODE.
1776 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
1777 allocate the basic dynamic root object.
1778 (scm_boot_guile): Added call to scm_init_root.
1780 * root.c, root.h: Added root smob.
1781 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
1782 functions: Implements dynamic roots mostly according to spec in
1783 SCM manual. Main difference is that the second argument is a
1784 throw handler rather than an error "thunk".
1786 * root.h: Added declaration of scm_init_root.
1788 * root.c: Added #include "genio.h", #include "smob.h", #include
1789 "pairs.h", #include "throw.h", #include "dynwind.h", #include
1791 (scm_init_root): Added #include "root.x".
1793 * throw.c: Added #include "stackchk.h"
1794 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
1795 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
1796 can be used in scm_call_with_new_root; Added reenabling of stack
1797 checking when catching a throw.
1799 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
1801 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
1803 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
1804 element is not found, as per R4RS.
1806 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1808 * list.c: Doc fixes throughout.
1810 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1812 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
1813 declare the char * to be const. Avoids a warning in rgx.c.
1815 * ports.h: spelling fix.
1817 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
1820 * load.c (scm_sys_try_load_path): throw an error if file not found
1821 (like it says it in NEWS).
1823 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1825 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
1826 PROPS slot to '(), not #f; it's an empty alist.
1828 * throw.h, throw.c: Use SCM_P instead of #if hair.
1830 Remove special support for uncaught throws; see throw.c for
1832 * throw.c (uncaught_throw): New function.
1833 (scm_ithrow): Call uncaught_throw if we don't find a throw
1834 target; don't mess with scm_bad_throw_vcell.
1835 (scm_bad_throw_vcell): Variable deleted.
1836 (scm_init_throw): Don't initialize it.
1838 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
1841 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1843 * numbers.c (scm_istr2int): If the number is short (as most
1844 numbers are), just call scm_small_istr2int to deal with it.
1845 (scm_small_istr2int): New function, created by un-#ifdefing the
1846 non-bignum version of scm_istr2int and renaming it.
1848 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
1850 * load.c (scm_sys_try_load): don't check whether value returned
1851 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
1852 Change the Scheme name from %try-load to primitive-load.
1854 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
1855 Can avoid passing a message, allowing it to be derived in the
1856 error handler (e.g., if we want to throw to the key both from
1859 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
1861 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
1862 references now have a new appearance which is more compact and
1863 also gives a clue about what the target of the reference is.
1864 By setting parameters in the print state, more fancy printing can
1865 be achieved. This is used by the (not yet commited) backtrace
1868 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
1870 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
1873 * print.c: Added #include "struct.h". Removed function
1876 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
1877 scm_iprin1. Removed prototype for scm_prlist.
1879 * arbiters.c (prinarb),
1880 async.c (print_async),
1881 debug.c (prindebugobj, prinmemoized),
1882 eval.c (prinprom, prinmacro),
1883 filesys.c (scm_fd_print, scm_dir_print),
1885 mallocs.c (prinmalloc),
1886 numbers.c, numbers.h (scm_floprint, scm_bigprint),
1887 smob.h (scm_smobfuns),
1888 srcprop.c (prinsrcprops),
1890 unif.c, unif.h (scm_raprin1, rapr1),
1891 variable.c (prin_var): Changed argument `int writing' to
1892 `scm_print_state *pstate'.
1894 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
1895 that it will be called before scm_init_print.
1897 * print.c (scm_prin1): Print states are now allocated when calling
1898 scm_prin1 and then passed around to all printing functions as an
1899 argument. A cache `print_state_pool' enables reuse of print
1901 (scm_make_print_state): New function.
1902 (scm_iprin1): Adaption to print states.
1903 (scm_iprlist): An initial "hare and tortoise" scan brings down
1904 time complexity to O (depth * N). (Better time complexity will be
1905 achieved when the printing code is completely rewritten.)
1907 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1909 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
1910 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
1911 it gets done whether or not the cache variable has a value.
1913 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
1915 Distinguish #f and ().
1916 * __scm.h: #undef SICP.
1917 * pairs.h (SCM_EOL): Delete this definition, equating it with
1919 * tags.h (SCM_EOL): Give it a new definition here; I think I found
1920 the value it used to have. Doc fixes, too.
1922 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
1924 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
1925 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
1926 Lord's implementation of structs, allowing for tail arrays as
1927 described in the manual. Also fixed some bugs. (Both the interface
1928 and the implementation should be improved.)
1930 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
1932 * print.c, print.h: Closures now print like #<procedure foo (x)>.
1933 People who whish to see the source can do `(print-enable 'source)'.
1934 Removed #ifdef DEBUG_EXTENSIONS.
1936 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1938 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
1939 integer (assuming for now accepting an integer is a good thing).
1941 * error.c, fports.c: replace use of %S in lgh_error args with %s.
1942 %S will be used instead for write'ing arguments.
1944 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
1945 asserts. fix a few other asserts.
1946 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
1947 scm_uniform_vector_ref, scm_array_set_x,
1948 scm_dimensions_to_unform_array): change args in
1949 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
1950 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
1951 scm_substring_fill_x): likewise.
1952 gsubr.c (scm_gsubr_apply): likewise.
1953 eval.c (SCM_APPLY): likewise.
1955 * eval.c (4 places): replace scm_everr with lgh_error or
1958 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
1959 scm_memory_error): new procedures.
1960 scm_everr: deleted. can use scm_wta, dropping first two args.
1961 scm_error: convert NULL subr to SCM_BOOL_F.
1963 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
1966 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
1969 * error.c, error.h: new error keys: scm_arg_type_key,
1970 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
1972 scm_wta: reimplement using lgh_error instead of scm_everr.
1974 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
1976 * gdbint.c: scm_lread now has one more argument.
1978 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
1979 scm_port_\1; Added mutator scm_set_port_filename_x (used when
1980 loading source from non-file ports, which, e. g., happens when
1981 using the Emacs interface).
1983 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
1986 * read.c: Added code for recording of positions of source code
1987 expressions; New functions: recsexpr, scm_lreadrecparen;
1988 _scm_make_srcprops --> scm_make_srcprops
1989 (scm_flush_ws): Removed updating of positions counters. This work
1990 is already done by scm_gen_getc
1992 * read.h: Added prototype for scm_lreadrecparen
1994 * print.c: Added #include "alist.h"
1996 * eval.c: Added #include "hash.h"
1998 * eq.c: Added #include "ramap.h"
2000 * options.c: Documentation fixes.
2002 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
2003 (scm_init_srcprop): Adjusted size of initial source-whash. Name
2004 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
2005 --> scm_make_srcprops
2007 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
2008 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
2009 function calls in the definition of the whash access macros.
2011 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
2013 * init.c (scm_boot_guile): Add level of indirection to
2014 scm_boot_guile_1() to ensure that stack base pointer is properly
2015 initialized. There was no guarantee that variable i was the
2016 highest/lowest variable on stack (i.e. the call frame of
2017 scm_boot_guile was not completely protected from gc).
2019 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
2021 * ports.h (scm_port_table): put back file_name, it will be used to
2022 support debugging. Undo related changes in fports.c, ioext.c,
2025 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2027 * ports.h (scm_port_table): remove file_name member for now, it seems
2029 * fports.c (scm_open_file): don't set file_name in PTAB.
2030 (prinfport): don't use file_name in PTAB.
2031 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
2032 * ports.c (scm_add_to_port_table): don't intialize file_name.
2033 (scm_port_file_name): remove for now.
2034 * gc.c (scm_gc_mark): don't mark PTAB file_name.
2036 * fports.h (scm_mkfile): prototype deleted.
2037 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
2039 * debug.c, unif.c: use scm_out_of_range instead of
2040 wta for range errors (ASSERT still needs work).
2042 * error.c, error.h (scm_out_of_range): new procedure.
2044 * error.c, error.h (scm_out_of_range_key): new key.
2046 * posix.c (scm_sync): #else was missing.
2048 * error.c, error.h: append _key to names scm_num_overflow and
2051 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
2052 of consing an empty list.
2053 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
2054 of macros, saves code and string space.
2055 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
2056 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
2057 lower case. Rename scm_syserror_m to scm_syserror_msg.
2058 error.h: prototypes for new procedures.
2060 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
2062 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
2064 * error.c, error.h: setup scm_num_overflow key.
2066 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
2067 Remove definition of SCM_OVSCM_FLOW.
2069 * fports.c (scm_open_file): use SCM_SYSERROR_M.
2071 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
2072 explicit message and args.
2074 * error.c, error.h, __scm.h: change system_error_sym to
2077 * error.c (system_error_sym): remove leading %% from the Scheme name
2080 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
2082 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2084 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
2085 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
2086 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
2087 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
2088 renamed. (These were introduced by unsupervised name
2091 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2093 * print.c: Added code for detection of circular references during
2094 printing. (init_ref_stack, grow_ref_stack): New functions. Added
2095 a hook for printing of closures (accessible via print options).
2096 This leads to a split of calls to scm_iprin1 into two classes:
2097 elementary print operations (e. g. the code which prints a smob)
2098 still use scm_iprin1 while top level calls (like scm_display) use
2099 scm_prin1. scm_prin1 begins by clearing the data structure used
2100 to record reference information.
2102 * print.h: Added declarations of scm_prin1 and scm_prlist.
2104 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
2106 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
2108 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
2110 * error.c (err_head): scm_iprin1 --> scm_prin1
2112 * debug.c: Adjusted header comment.
2116 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2118 * strerror.c: Doc fix.
2120 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2122 * gdbint.c (gdb_read): Now possible to run during GC.
2123 (unmark_port, remark_port): New functions.
2125 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
2127 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
2128 of allocating a new string object. Also, increase size by
2129 the factor 2 instead of 1.5.
2131 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
2133 * __scm.h (SCM_P): Corrected to run under traditional C.
2135 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
2138 * async.c: Calls to scm_sysintern corrected.
2140 * async.h (scm_async_clock): Redundant declaration removed.
2142 * continuations.c (scm_dynthrow): Redundant declaration removed.
2144 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
2145 Definition typos corrected.
2147 * debug.h: Missing declarations of functions in debug.c added
2150 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2151 Missing declarations to functions in eval.c added.
2153 * filesys.c: Possibly uninitialized variable rv.
2155 * gc.h (scm_object_addr, scm_unhash_name): Missing
2156 declarations of functions defined in gc.c added.
2158 * genio.c: Possible typos str_data -> wstr_data. ???
2160 * genio.c: Possibly unintended shadowing of local variable
2161 `int c' (gotos out of scope of inner `c'). ???
2163 * init.c: Uninitialized `SCM last' may be used.
2165 * ioext.h: (scm_sys_isatty_p): Typo.
2167 * list.h (scm_list_head): Missing prototype for function in
2170 * numbers.c (scm_two_doubles): Changed from extern to static
2171 (is used only within numbers.c).
2173 * numbers.h: Repeated declarations removed.
2175 * ports.h (scm_close_all_ports_except): Declaration for the
2176 function defined in ports.c added.
2178 * posix.h: Missing declarations added.
2180 * procs.h (scm_make_subr_opt): Missing declaration added.
2182 * socket.h (scm_sys_gethost): Missing declaration added.
2184 * socket.h: Redundant declarations removed (they are in fdsocket.h).
2186 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
2187 Missing declarations added.
2189 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
2191 * struct.c: Uninitialized variable `SCM answer' may be used.
2193 * unif.c (l2ra): Declaration prototype.
2195 * unif.c (scm_array_equal_p): Dummy definition removed (it is
2196 defined in ramap.c).
2198 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
2199 Redundant declarations removed (they are in ramap.h).
2201 * variable.h (scm_make_udvariable,
2202 scm_make_undefined_variable): Declaration corrected to
2203 correspond variable.c.
2205 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
2206 Missing declarations added.
2208 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
2210 * Makefile.in (distclean): Don't forget to delete fd.h.
2212 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2214 * fd.h.in, tags.h: Trivial cleanups.
2216 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
2217 marksweep.h just declared functions from gc.c.
2218 * gc.h, libguile.h: Don't #include "marksweep.h".
2219 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2220 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
2221 dependencies updated.
2223 * libguile.h: Don't #include "files.h"; it's been deleted.
2225 * files.c (scm_sys_delete_file): Moved to filesys.c.
2226 File is now empty; deleted.
2228 * filesys.c: scm_sys_delete_file is now here. Remove
2229 #if's; they seem to rely on remnants of an old portability
2230 regimen. If the problems come up again, solve them properly,
2231 using autoconf. Specifically: Don't test M_SYSV, and #define
2232 remove to be unlink if it's #defined; don't use remove just
2233 because HAVE_STDC_HEADERS is #defined.
2234 * filesys.h: Add declarations for scm_sys_delete_file.
2235 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2236 files.o, files.h, files.c, and files.x.
2237 * init.c: Don't #include "files.h", and don't call scm_init_files.
2239 Use SCM_P instead of PROTO; the latter intrudes on the user's
2241 * params.h: Deleted; definition of SCM_P moved to...
2242 * __scm.h: ... here, where it replaces PROTO macro.
2243 * libguile.h, smob.h: Don't #include "params.h".
2244 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
2245 smob.h: Fix prototypes accordingly.
2246 * Makefile.in: Update dependencies.
2247 (inner_h_files): Remove params.h.
2249 * gc.c: #include "gc.h"; every module should include its header,
2250 to let the compiler cross-check the declarations against the
2253 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2254 simpos.h: #include "libguile/__scm.h".
2256 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2258 * init.c: Don't forget to #include smob.h and init.h.
2259 * Makefile.in: Dependencies updated.
2261 * smob.h: Use PROTO instead of #if __STDC__.
2263 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2265 * __scm.h: Doc fixes.
2267 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2268 <angles>; this allows `make depends' to work properly.
2270 * libguile.h: #include smob.h and pairs.h before the others; they
2271 define typedefs used by other headers.
2273 C files should #include only the header files they need, not
2274 libguile.h (which #includes all the header files); the pointless
2275 recompilation was wasting my time.
2276 * Makefile.in (all .o dependency lists): Regenerated.
2277 * libguile.h: Don't try to get a definition for size_t here...
2278 * __scm.h: Do it here.
2279 * _scm.h: Since this is the internal libguile header, put things
2280 here that all (or a majority) of the libguile files will want.
2281 Don't #include <libguile.h> here; that generates dependencies on
2282 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2283 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2284 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

2381 * weaks.c: Get "weaks.h".
2383 * stackchk.h: #include "libguile/debug.h",
2385 * print.h, read.h: #include "options.h", since everyone who uses
2386 either of these files will need that.
2388 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2389 anyone who uses this file will need them to define the smob
2390 printing functions. Also, get markers.h, since people will need
2391 to #define the mark functions.
2393 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2394 * ports.h: ... to here.
2396 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2397 don't rely on archaic C default type rules.
2399 * fports.h: #include "libguile/ports.h", since you need that in
2400 order to parse this.
2402 * genio.h: #include "libguile/print.h", because you need that to
2403 parse this; don't bother #including "ports.h", since print.h gets
2406 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2408 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2409 this; it's now a reference to an element of *scm_root.
2411 * debug.h: Don't #include "options.h"; the compiler won't be able
2412 to find that once the headers are installed; instead, #include
2413 "libguile/options.h".
2414 * gc.h: Same, with marksweep.h.
2415 * mbstrings.h: Same, with symbols.h.
2416 * scmhob.h: Same, with _scm.h.
2417 * smob.h: Same, with params.h.
2419 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2420 C files; there's no need for this, and it forces recompilations
2423 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2425 * error.c (scm_error): declare scm_error_callback.
2427 * error.h: prototype for scm_error_callback.
2429 * __scm.h: define lgh_error.
2430 (SCM_SYSERROR): redefine using lgh_error.
2432 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2434 * error.c (scm_error): new procedure.
2436 * error.h: prototype for scm_error.
2438 * Makefile.in (install): install scmconfig.h from the current
2439 directory, not $(srcdir).
2441 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2443 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2444 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2445 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
2446 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
2447 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
2448 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2449 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2450 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2451 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2452 vports.h, weaks.h: #include "libguile/__scm.h", not
2453 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2454 dependencies are within libguile properly.
2456 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2458 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2459 when scmconfig.h doesn't exist.
2461 * load.c (scm_sys_try_load): Correct spelling.
2463 * feature.c (scm_loc_features): Make this static.
2465 * Makefile.in (libpath.h): Omit trailing slash from path. We
2466 shouldn't require it of users, so why put it here?
2468 Move code to initialize and search %load-path from ice-9 to C
2469 code, so we can use the load-path to find the ice-9 boot code;
2470 this makes it easier to run Guile without installing it. See
2471 corresponding changes in guile/Makefile.in.
2472 * feature.c: Move stuff concerned with the load path to load.c.
2473 (scm_compiled_library_path): Deleted.
2474 Don't #include libpath.h here.
2475 * feature.h: Don't mention scm_compiled_library_path.
2476 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2477 <sys/stat.h>, and <unistd.h> (if present).
2478 (R_OK): #define if the system hasn't deigned to.
2479 (scm_loc_load_path): New variable.
2480 (scm_init_load_path, scm_sys_search_load_path,
2481 scm_sys_try_load_path): New functions.
2482 (scm_init_load): Initialize scm_loc_load_path to point to the
2483 value cell of the Scheme %load-path variable.
2484 * load.h: Add declarations for scm_sys_search_load_path,
2485 scm_sys_try_load_path.
2486 * init.c: Call scm_init_load_path.
2487 * Makefile.in (feature.o, load.o): Dependencies updated.
2489 * load.c, load.h: Rewrite using PROTO macro.
2491 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2493 * gc.c (scm_cellp): New function: C predicate to determine if an
2494 SCM value can be regarded as a pointer to a cell on the heap.
2496 * gc.h: Added declaration of scm_cellp.
2498 * gdb_interface.h: New file: The GDB interface header from the GDB
2501 * gdbint.c: New file: GDB interface.
2503 * gdbint.h: New file: GDB interface.
2505 * libguile.h: Added #include <libguile/gdbint.h>.
2507 * init.c (scm_boot_guile): Added scm_init_gdbint.
2509 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2510 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2511 found if object files and source are kept separate).
2513 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2515 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2517 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2519 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2520 TK_SRC_DIR; they're not relevant any more.
2522 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2523 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2525 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2527 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2528 search path, so we can find the <libguile/MUMBLE.h> headers.
2530 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2532 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2533 implicit in the .c.o rule.
2534 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2537 Put the library path in a header file, instead of passing it on
2538 the command line in every compilation.
2539 * Makefile.in (libpath.h): New target.
2540 (feature.o): Depend on libpath.h.
2541 (clean): Delete libpath.h.
2542 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2543 * feature.c: ... #include "libpath.h" here.
2544 * .cvsignore: Ignore libpath.h.
2546 Don't install the unwashed masses of Guile header files in the
2547 main #include path; put most of them in a subdirectory called
2548 'libguile'. This avoids naming conflicts between Guile header
2549 files and system header files (of which there were a few).
2550 * Makefile.in (pkgincludedir): Deleted.
2551 (innerincludedir): New variable; this and $(includedir) are enough.
2552 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
2553 (installed_h_files): Divide this up. Now this variable lists
2554 those header files which should go into $(includedir) (i.e. appear
2555 directly in the #include path), and ...
2556 (inner_h_files): ... this new variable says which files appear in
2557 a subdirectory, and are referred to as <libguile/mumble.h>.
2558 (h_files): List them both.
2559 (install): Create innerincludedir, not pkgincludedir. Put
2560 the installed_h_files and inner_h_files in their proper places.
2561 (uninstall): Corresponding changes.
2562 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2563 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2564 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
2565 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
2566 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
2567 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2568 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2569 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2570 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2571 vports.h, weaks.h: Find __scm.h in its new location.
2572 * __scm.h: Find scmconfig.h and tags.h in their new locations
2573 (they're both "inner" files).
2575 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
2577 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
2579 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2581 * posix.c: Doc fixes.
2583 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
2585 * socket.c: Don't include a prototype for inet_aton; just use a
2586 K&R style declaration, to avoid warnings but minimize the chance
2587 of conflicts with the system.
2589 On NextStep, <utime.h> doesn't define struct utime, unless we
2590 #define _POSIX_SOURCE before #including it.
2591 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
2592 * acconfig.h: New comment text for above CPP symbol.
2593 * configure.in: Call it.
2594 * posix.c: #define _POSIX_SOURCE if it seems necessary.
2596 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
2598 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
2599 testing for __EMX__.
2601 * posix.c: #include <libc.h>, if it exists.
2603 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
2604 don't even know if the latter exists.
2606 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
2607 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
2608 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
2610 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
2612 (scm_init_posix): Use them when initializing the Scheme constants
2615 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2617 * Makefile.in (libdir, includedir, bindir): Use the
2618 autoconf-supplied values, instead of deriving them ourselves.
2619 (pkgincludedir, datadir, pkgdatadir): New variables.
2620 (install, uninstall): Put the header files in a special
2621 subdirectory, not in the main search path.
2623 * Makefile.in (ALL_CFLAGS): Provide the proper value for
2624 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
2626 * Makefile.in (IMPLPATH): Deleted; never used.
2628 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
2629 on the Tcl/Tk source any more.
2630 (INCLUDE_CFLAGS): Remove references to the above.
2632 * Makefile.in (version.o): Corrected dependencies.
2634 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
2636 * libguile.h: #include "version.h"
2638 * init.c (scm_boot_guile): Call scm_init_version.
2639 * gscm.c (gscm_run_scm): Call scm_init_version.
2641 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
2642 GUILE_VERSION): AC_DEFINE these.
2643 (acconfig.h): #undef the above symbols.
2645 * Makefile.in (libobjs): Add version.o.
2646 (installed_h_files): Add version.h.
2647 (c_files): Add version.c.
2648 (gen_c_files): Add version.x.
2649 (version.o): New rule.
2650 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
2651 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
2652 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
2653 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
2654 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
2655 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
2656 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
2657 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
2658 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
2659 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
2660 weaks.o): Add version.h to dependency lists.
2661 (markers.o): Remove duplicate rule.
2663 * version.h: New file.
2665 * version.c: New file.
2667 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2669 * symbols.c (scm_strhash): scm_downcase is now a function, not an
2670 array; use it appropriately. Since GCC is quite happy to
2671 subscript functions, it never warned us about this; we should use
2672 -Wpointer-arith in the future. I guess we never tested
2675 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2677 * socket.c: Doc and copyright fixes.
2679 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2681 * debug.c: Fixed and improved gdb support.
2683 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2685 * socket.c: Added declaration of inet_aton to avoid compiler
2686 warning. (Hope this solution is correct.)
2688 * stime.c: Added declaration of ftime. (This is missing in
2691 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
2693 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2695 * Makefile.in (c_files): add strerror.c.
2697 * strerror.c: new file from Emacs' sysdep.c.
2698 maybe configure should also check for sys_errlist.
2700 * configure.in (AC_REPLACE_FUNCS): add strerror.
2702 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2704 * debug.c (scm_init_debug): Added initialization for
2705 scm_evaluator_traps.
2707 * debug.h, debug.c: Various name changes.
2708 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
2709 "debug-options-interface". See commentary in options.c.
2711 * options.h, options.c: Options now have documentation strings.
2712 Also added a long explanatory commentary.
2714 * eval.c, print.h, print.c, read.h, read.c: Modifications to
2717 * gscm.c, init.c, root.c, throw.c: Bug fixes:
2718 last_debug_info_frame is now updated in all cases.
2720 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
2723 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2725 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
2726 Added option STACK_CHECKING.
2728 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
2730 * Makefile.in: Added {debug,options,srcprop}.{h,c}
2732 * __scm.h: Removed symbols for debugging support.
2734 * acconfig.h: Added symbols for debugging support.
2736 * configure.in: Added user option for debugging support.
2737 --enable-debug will include the debugging code into libguile.a.
2739 * continuations.c (scm_make_cont): Enlarged the #if 0 around
2740 scm_relocate_chunk_to_heap.
2742 * debug.c: New file: low-level debugging support. It also
2743 includes support for debugging with gdb. (The extensions to gdb
2744 are written by Per Bothner at Cygnus.)
2746 * debug.h: New file: low-level debugging support.
2748 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
2749 argument pairs. Extensive modifications to the debugging
2750 evaluator. Added "SECTION:" commentaries to clarify what happens
2751 when, during double compilation. Renamed EVALIMP --> EVALIM.
2752 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
2753 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
2754 the beginning of the file. New procedure: scm_unmemocopy.
2755 Added some global state variables needed by the debugging
2756 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
2757 check_entry, check_apply, check_exit, debug_options and
2758 evaluator_traps. New acro: undefine.
2760 * eval.h: Renamed EVAL --> XEVAL.
2762 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
2763 --> scm_make_weak_key_hash_table.
2765 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
2766 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
2768 * libguile.h: Conditionally include debug.h
2770 * objprop.c (scm_object_properties, scm_set_object_properties_x):
2771 scm_object_properties shouldn't return handle. `handle' now gets
2772 initialized in scm_set_object_properties_x. scm_object_properties
2773 doesn't any longer create an entry in scm_object_whash.
2775 * options.c: New file: handling of run time options.
2777 * options.h: New file: handling of run time options.
2779 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
2781 * print.c: New procedure: scm_print_options
2783 * print.h: Defines for print options.
2785 * read.c: New procedure: scm_read_options
2787 * read.h: Defines for reader options.
2789 * root.h: Added scm_source_whash among scm_sys_protects.
2791 * srcprop.c: New file: source properties.
2793 * srcprop.h: New file: source properties.
2795 * throw.c (jbsmob): Jump buffers are now correctly allocated.
2796 (Bug found by A. Green.)
2798 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2800 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2802 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
2804 * libguile.h: #include "objprop.h"; I guess this was forgotten.
2806 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
2807 and should be called by the final client.
2809 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
2811 * gc.h: Use the PROTO macro when declaring functions.
2812 * gc.c: Use the PROTO macro when declaring static functions.
2813 Remove the CPP hair around function definitions.
2815 * gc.c (scm_init_storage): Initialize scm_asyncs.
2817 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
2818 preprocessor symbol; "__scm.h" is where it might get #defined.
2819 * __scm.h: Similar: #include <scmconfig.h> before testing
2822 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
2824 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
2826 * init.c (scm_boot_guile): Add init_func argument; call
2827 (*init_func) instead of calling scm_appinit; it's ucky to
2828 hard-code names for the user's procedures.
2829 * init.h (scm_boot_guile): Adjust declaration.
2831 * __scm.h (PROTO): New macro, for declaring functions with
2834 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
2835 eliminate all the __STDC__ conditionals.
2836 (scm_boot_guile): Add declaration.
2837 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
2838 Remove __STDC__ conditionals around function definitions; the
2839 declarations in init.h will provide the same information, more
2842 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
2843 complain about it in the error message; the error message is
2844 adequate without that note, and there's nothing the user can do
2847 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
2849 * Makefile.in (ancillary): Drop def.sed.
2851 * posix.c (scm_init_posix): Use numeric values, rather than
2852 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
2853 F_OK. The symbols aren't available on some systems, and I'm
2854 pretty sure their values are fixed by common widespread practice.
2855 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
2857 More functions unavailable on some systems.
2858 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
2859 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
2861 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2862 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
2863 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
2864 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
2865 stub that signals an error as the #else.
2867 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
2869 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
2871 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
2873 * unif.c: include ramap.h.
2875 * read.c (endif): case_insensative_p renamed case_insensitive_p.
2877 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
2879 * ports.c: include sys/ioctl.h.
2881 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
2883 * configure.in: check for sys/ioctl.h.
2885 * ports.c: include <malloc.h> not "malloc.h".
2887 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2889 * fports.c: remove ttyname and tmpnam declarations.
2891 * posix.c: fewer ttyname declarations.
2893 * fports.c: include <string.h> not "string.h".
2895 * init.c, ioext.c: include string.h and unistd.h.

2919 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
2921 Changes for NeXT, suggested by Robert Brown.
2922 * configure.in: Call AC_TYPE_MODE_T.
2923 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
2924 NeXT. Put header file list in alphabetical order.
2925 * configure, scmconfig.h.in: Regenerated.
2926 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
2928 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
2931 * acconfig.h: New file, providing documentation for the CPP
2932 symbols defined in configure.in
2933 * acconfig-1.5.h: Removed; superceded by the above.
2935 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>

2941 * ioext.c (fileno): renamed from %fileno.
2942 (soft-fileno): deleted.
2944 * ports.c (scm_port_revealed): don't need to check for -1 from
2946 (scm_set_port_revealed_x): return unspecified, not #f.

2956 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2958 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
2959 This is necessary on Ultrix, and doesn't hurt portability.
2961 * Makefile.in (dist-dir): New target, implementing a new dist system.
2962 (installed_h_files): Put in alphabetical order.
2963 Remove duplicate entries for markers.h and unif.h.

2965 (ancillary): Renamed from anillery; all uses changed. Remove
2966 PLUGIN; it's a directory, and needs special treatment in dist-dir.

2969 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
2971 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
2972 every if must have an else, or else the whole command has a
2973 non-zero exit code whenever the if's condition is false.
2975 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>

3040 matter so long as it is non-0 (got rid of "* 4").
3042 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
3044 * gscm.h: gscm_mkarray eliminated (presumably was not being used
3045 since its definition was bogus).
3047 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
3049 * mallocs.[ch]: back again (for rx at least).
3051 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
3053 * ports.c: removed functions relating to the mapping between ports
3054 and descriptors. (That stuff is unix-specific and should be collected
3055 in a separate library).

3062 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
3063 handled correctly (SCM_FREEP was applied to them) -- test for
3064 NIMP. Keys in weak hash tables were spuriously (though harmlessly)

3232 initialization to fix a race condition.
3234 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

3258 set the multi_byte flag correctly in symbols. This is wrong.
3259 intern_obbary_soft and msymbolize should take an extra parameter.
3260 Also, weird multibyte symbols don't print correctly.
3261 The weird symbol syntax is also a bit bogus (emacs doesn't quite
