1 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3 * acconfig.h: Removed PACKAGE.
5 * scmconfig.h.in: Regenerated.
7 * snarf.h: g++ says it's non-portable not to specify the first
8 argument in a varargs declaration. I introduced the first
9 argument by using preprocessor conditionals.
11 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
13 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
14 (scm_freopen): use RO string macros for filename and modes.
15 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
17 * posix.c (scm_getgrgid): simplify conversion of name to C string.
18 (scm_mknod): use RO string macros for path.
20 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
21 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
23 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
24 use SCM_ROSTRINGP and SCM_ROCHARS.
26 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
28 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
31 * ramap.c (scm_ra_matchp, scm_ra_matchp, scm_array_fill_int, racp,
32 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
33 support for byte vectors.
35 * print.c (scm_iprin1): Limit number of vector elements printed
36 according to pstate->length.
38 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
40 * backtrace.c (scm_display_error_message): don't segv if message
43 * error.h: prototype for scm_error_scm.
45 * error.c (scm_error_scm): new procedure, reimplements scm-error
46 in C and uses scm_error.
48 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
50 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
51 pointer to the Scheme variable read-hash-procedures and intern it
52 in scm_init_read. Modify scm_read_hash_extend and
53 scm_get_hash_procedure to use the pointer.
55 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
57 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
58 (SCM_KEYWORD_STYLE): defined.
60 * read.c (scm_read_opts): add a keywords option. This isn't a
61 boolean option, in case someone wants to add support for DSSSL
63 Setup scm_keyword_prefix symbol.
64 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
66 * I've left keyword support disabled by default, since it doesn't
67 seem to break the module system and it gives R4RS standard behaviour.
68 It can be reactivated with (read-set! keywords 'prefix).
70 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
72 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
73 before constructing arbiter.
75 * eval.c (scm_m_define): Bugfix: Check that the object is a
76 closure before setting the procedure property!
78 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
80 * ports.c: Removed `ungetc-char-ready?'.
82 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
84 * read.c (scm_init_read): intitialise scm_read_hash_procedures
85 (idea from Mikael: make it a pair so scm_permanent object only
87 (scm_read_hash_extend): don't call scm_permanent_object.
88 (ideas from Mikael): if chr is already in the list, replace its
89 procedure instead of appending it again. If proc is #f, remove
91 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
93 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
95 * gdbint.c (gdb_read): update scm_lreadr usage.
97 * load.h: update prototypes.
99 * load.c (scm_primitive_load, scm_read_and_eval_x,
100 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
102 * read.h: add prototype for scm_read_hash_extend. Change args for
105 * read.c (scm_read_hash_procedures): new variable.
106 (scm_read_hash_extend): new procedure.
107 (scm_get_hash_procedure): new procedure.
108 * (scm_lreadr): use scm_get_hash_procedure instead of an argument
109 for extended # processing.
110 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
111 scm_read_token): remove case_i, sharp arguments. Change callers.
113 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
115 * read.h (SCM_N_READ_OPTIONS): increase to 3.
116 (SCM_CASE_INSENSITIVE_P): define.
118 * read.c: add case-insensitive option to scm_read_opts.
119 * (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
120 to determine whether to convert symbol case.
121 (default_case_i): definition removed.
122 * read.c (scm_read_token): if case_i, downcase ic before doing
125 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
127 * configure.in: Added configuration option `guile-debug'.
128 Configure with --enable-guile-debug if you want a bunch of extra
129 functions used for debugging when developing Guile.
131 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
133 * procs.c (make-cclo): New undocumented debugging procedure: Make
134 compiled closure with internal procedure PROC and length LENGTH.
135 Only compiled if GUILE_DEBUG is defined.
137 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
139 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
141 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
143 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
144 with 3 or more args internally to the evaluator.
146 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
148 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
149 with 3 or more args internally to the evaluator. This is mainly
150 because we don't want to pass entry and exit points of the
151 debug support twice, but it also seems to increase the speed of
152 the evaluator for such calls (e. g. (+ 1 2 3)).
154 * * backtrace.c (scm_display_application): New procedure:
155 display-application; Set fancy printing parameters individually
156 for different types of display (backtrace, error, application).
157 (These should of course be customizable!)
159 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
160 clear the CHECK-flags.
162 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
164 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
166 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
168 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
169 from pairs with a GLOC in the car.
171 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
172 otherwise `symbol-hash' will behave badly.
173 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
174 we get segmentation fault!
176 * * symbols.c: Added #include "weaks.h". New functions:
177 `builtin-bindings' and `builtin-weak-bindings'. (These will be
178 moved to an extraneous library when we split libguile.)
180 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
182 * filesys.c (scm_stat): stat now takes fport arguments too as
183 documented in the manual.
185 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
187 * debug.c (scm_single_step): Bugfix: Call continuation with
188 scm_call_continuation instead of throwing to it.
190 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
192 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
193 argument wasn't declared to be optional.
195 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
197 * stime.c (scm_init_stime): Add feature "current-time".
199 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
201 * throw.h: prototype for scm_exit_status.
202 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
203 args to derive an exit status. Allows (quit) to work from a
205 (scm_exit_status): new function.
208 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
210 * eval.c (scm_deval): Removed some old code.
211 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
213 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
216 * symbols.c (msymbolize): Bugfix: Must initialize property list to
219 * procs.c: Introduce the existent C function scm_thunk_p at the
220 Scheme level as well.
222 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
224 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
225 used from C to easily lookup the value of a symbol in the current
228 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
230 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
231 scm_init_unif in this file. This will also fix a previous problem
234 * configure.in: Added AM_MAINTAINER_MODE
236 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
238 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
241 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
243 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
244 source files that are not always included in libguile but should
245 have their dependencies calculated by automake. This variable is
246 recognized by automake, no further magic is needed.
247 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
248 to deal exclusively with *.lo files, as it seems. The *.o files
249 are built automatically when the corresponding *.lo file gets
252 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
254 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
257 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
259 * unif.c (scm_array_set_x): minor change to argument error checking.
261 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
263 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
264 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
265 They should only be included in the library at configure.in's
267 (libguile_la_LDADD): Include the appropriate .lo files here.
268 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
269 so we know when to build them (and their .lo bretheren).
270 * configure.in (LIBLOBJS): New substituted variable. We let
271 configure decide which .o files to include in LIBOBJS, and then
272 put the corresponding list of .lo files in LIBLOBJS. The latter
273 is what we pass to libtool.
274 * Makefile.in, configure: regenerated.
276 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
278 * symbols.c (scm_sysintern0): New function. Contains the core of
279 old scm_sysintern but doesn't take a second value argument.
280 (scm_sysintern): Now uses scm_sysintern0.
281 (scm_sysintern_no_module_lookup): Renamed to
282 scm_sysintern0_no_module_lookup and doesn't take a second value
285 * symbols.h (scm_sysintern0: Added declaration.
287 * options.c (scm_init_opts): Use scm_sysintern0 instead of
288 scm_sysintern when interning option keys. Otherwise we risk
289 destroying the values of already interned variables.
291 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
292 scheme-level boolean (use SCM_NFALSEP).
294 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
296 (scm_backtrace): New function. (C version of old function from
297 boot-9.scm) Motivation: Make it possible to display backtraces
298 without depending on boot-9.scm. (I'm uncertain if this
299 motivation is good enough...)
301 * root.h (scm_root_state): Add member the_last_stack_var.
302 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
304 * root.c (mark_root): Mark scm_the_last_stack_var.
306 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
309 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
311 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
312 1. mark_lazy_catch didn't mark the smob.
313 2. Both functions above have standard variants:
314 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
315 free_lazy_catch --> scm_free0.
317 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
319 * throw.c (scm_internal_lazy_catch): New function.
320 (scm_lazy_catch): Rewritten to use it.
321 (scm_ithrow): Handle the new lazy catch representation.
322 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
323 that doesn't have a jmpbuf is a lazy catch clause.
324 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
325 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
326 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
328 (scm_init_throw): Register the new lazy-catch smob type.
329 * throw.h (scm_internal_lazy_catch): decl for new function.
331 * throw.c (scm_internal_catch): Doc fixes.
333 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
334 configure.in. Including this might cause problems if applications
335 that link against libguile include their own copies of alloca, but
336 if they're using autoconf, they should be adding libguile to LIBS
337 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
338 the copy in libguile, and things will be okay. (I think.)
340 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
342 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
344 strop.h: move prototypes too.
346 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
348 * posix.c (scm_init_posix): don't intern EINTR since it's now done
351 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
352 etc. I deleted them from filesys.c long ago, but didn't
353 notice they were here too (although ineffective since
354 sys/stat.h wasn't included).
356 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
358 * eval.c: Don't define alloca in GCC case. gcc will automatically
359 use __builtin_alloca if appropriate.
361 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
363 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
364 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
365 that values of automatic variables are preserved. See comments
366 for safe_setjmp for details.
368 Change from Thomas Morgan:
369 * variable.c: Include eq.h.
370 (var_equal): New function.
371 (variable_smob): Use var_equal as the discriminator for variables.
373 * throw.c (s_throw): Remove extraneous declaration.
375 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
376 * eval.c: Add necessary CPP cruft to support that.
377 * configure, Makefile.in, scmconfig.h.in: regenerated.
379 Change from Thomas Morgan:
380 * procprop.c (scm_procedure_properties): Convert the Scheme
381 boolean returned by scm_procedure_p into a C boolean before using
382 it as a condition for SCM_ASSERT.
383 (scm_procedure_property): Likewise.
385 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
386 indications of Unixness.
389 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
391 * * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
393 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
395 * read.c (scm_lreadr): use scm_misc_error to improve one of the
396 "unknown # object" error messages.
398 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
399 (scm_i_index) and declare it static. Add a 'direction' argument
400 to indicate what way the search should go.
401 (scm_i_index): throw out-of-range error instead of wrong-type-arg
403 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
404 strop.h: remove scm_i_index, scm_i_rindex prototypes.
406 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
408 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
410 * * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
411 to avoid clash with various scsh forks.
413 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
415 The following two changes (ramap.c, throw.c) are motivated by the
416 apparent unportability of forward declarations of static arrays of
417 the form `static foo bar[];'.
419 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
420 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
422 * throw.c (scm_throw): Moved above scm_ithrow.
424 * options.h: Removed the extern declarations of scm_yes_sym and
425 scm_no_sym since these are static.
427 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
429 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
431 * Makefile.am: remove AWK=@AWK@.
432 Add a rule for generating errnos.list.
433 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
435 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
436 don't extract errnos, just set a variable (avoids the
437 need to recompile error.c just because configure is run.)
439 * unif.h: update prototypes.
440 * unif.c (scm_uniform_array_read,write): change the offset and
441 length arguments to start and end, for consistency.
443 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
445 * ioext.h: update prototypes.
446 * * ioext.c (scm_read_delimited_x): replaces scm_read_line and
447 scm_read_line_x, it's a more general procedure using an
448 interface from scsh. read-line and read-line! are now defined
450 * Note that the new read-line trims the terminator
451 by default, previously it was appended to the returned string. An
452 optional argument specifies how to process the terminator (scsh
453 compatible). For the old behaviour: (read-line port 'concat).
454 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
455 returns a pair, but is converted to multiple values if the scsh
458 socket.h: update prototypes.
459 * socket.c (scm_recvfrom): for consistency with other procedures,
460 take start and end as separate optional arguments.
461 * (scm_recv, scm_recvfrom): don't allow the second argument
462 to be a size, only a buffer. Change the scheme names to
463 recv! and recvfrom!. Don't return the buffer.
465 * ioext.h, posix.h: move prototypes too.
466 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
467 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
468 "read.h" and "unif.h".
469 * ioext.c: include "chars.h"
471 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
473 * dynl.c: The dynamic linking and module registration functions
474 are now defined even when dynamic linking is not available for the
475 host system. Some of their functionality can be done without
476 dynamic linking; when it's really needed, they throw errors.
478 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
480 * configure.in: Only define DYNAMIC_LINKING when one of the system
481 dependent functions is detected.
482 * dynl.c (scm_dynamic_func): New function to get the address of a
483 function in a dynamic object.
484 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
485 produced by scm_dynamic_func as the thing to call.
487 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
489 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
490 (scm_register_module_xxx, scm_registered_modules,
491 scm_clear_registered_modules): New functions.
493 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
495 * symbols.c (scm_sysintern): Renamed to
496 scm_sysintern_no_module_lookup.
497 (scm_sysintern): New function to take the place of the old
498 scm_sysintern. It uses the current toplevel lookup closure to give
499 the symbol its value. This is a temporary hack to put packages
500 like gtcltk into their own module.
501 (scm_can_use_top_level_lookup_closure_var): New variable to tell
502 us whether `scm_top_level_lookup_closure_var' has been initialized
504 * eval.c (scm_init_eval): Set it.
506 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
508 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
509 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
511 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
513 * (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
514 scm_sys_dup): deleted: FD capability will be added to other
516 * Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
517 scm_fd_free, fd_smob, scm_intern_fd.
518 * (scm_open): renamed from scm_sys_open. Return a port instead of
519 an FD object. Make the mode argument optional.
520 * (scm_sys_create): deleted, it's just a special case of open.
521 (scm_init_filesys): move interning of constants O_CREAT etc.,
522 here (were previously using SCM_CONST_LONG macro).
523 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
525 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
526 include "fports.h" and <stdio.h>
527 (scm_stat, scm_select): don't support FD objects.
529 * error.h: adjust scm_syserror_msg prototype.
530 * error.c (scm_syserror_msg): take an extra argument for errno.
531 Using the global value didn't always work, since it could be
532 reset by procedure calls in the message or args arguments.
534 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
535 I don't understand why the check was there (and what about the
538 * strop.c (scm_string_copy): allow shared substrings to be copied.
540 * unif.h: corresponding change to prototypes.
541 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
542 recognize two new optional arguments: offset and length. Allow
543 the port argument to be an integer (file descriptor, for scsh).
544 Include <unistd.h> for "read" prototype.
546 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
548 * socket.c: don't include filesys.h.
550 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
552 * Makefile.am: add AWK=@AWK@ (?)
554 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
556 Add a rule to generate errnos.c from errnos.
557 * error.c (scm_init_error): include errnos.c.
558 * errnos_cnvt.awk: new file, converts the list of errno codes to
560 * errnos_get.c: new file.
561 * errnos.default: new file, contains errnos to try if they can't
562 be extracted from errno.h.
563 * configure.in: if using GCC, try and extract errno codes from
567 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
569 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
570 * Makefile.am: Made libguile into a libtool library.
571 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
572 Set libtool_libs to indicate that libguile is a libtool library.
573 See guile/ChangeLog for details.
574 * .cvsignore: ignore "*.lo", the libtool library objects.
576 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
578 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
579 use htons in getservbyport argument.
581 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
583 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
584 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
587 * objprop.c (scm_object_property): No need to take the CDR of the
588 value returned by scm_object_properties, since Aug 20 change.
590 * configure.in: When checking for struct linger, #include
591 <sys/types.h> as well as <sys/socket.h>. I've never known
592 <sys/types.h> to cause any portability problems, and Solaris's
593 <sys/socket.h> needs it.
594 * configure: Rebuilt.
596 I think the Sun compiler has chosen a perverse way to interpret
597 ANSI declarations combined with K&R definitions. We'll
598 appease it a little bit. But when it invades France, we fight.
599 * print.c (scm_iprlist): Change 'tlr' argument to an int.
600 * print.h (scm_iprlist): Here too.
601 * numbers.c (scm_divbigdig): Change definition to match
602 declaration in numbers.h.
603 * unif.c (scm_makflo): Change definition to match declaration in
606 * init.c (scm_boot_guile): Don't return the value of
607 scm_boot_guile_1. This function doesn't return a value;
608 scm_boot_guile_1 doesn't return a value (or return at all).
610 * eval.c (unmemocopy): Add a semicolon to appease the Sun
613 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
614 compile. I have a feeling this function is a bad idea anyway ---
615 one should always test for features, not systems.
617 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
618 semicolons. Only pure luck kept this from being noticed earlier.
620 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
622 * socket.c (scm_recvfrom): Added missing semicolon.
624 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
626 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
627 the buffer and start and end positions for scsh networking
630 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
632 * configure.in: Revert previous change to this file; the problem
633 is due to transient automake weirdness.
634 * configure: Rebuilt.
636 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
637 PLUGIN/guile.libs. configure generates the latter from the former.
638 * Makefile.in: Rebuilt.
640 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
641 need this if we install scripts, like guile-snarf.
642 * configure: Rebuilt.
644 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
646 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
648 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
650 * socket.c (scm_addr_vector): fix faulty scm_listify.
652 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
654 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
655 style block comment is no longer considered an error.
657 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
659 * PLUGIN/guile.libs.in: New file.
660 * PLUGIN/guile.libs: Removed from repository.
661 * configure.in: Create PLUGIN/guile.libs from
662 PLUGIN/guile.libs.in. This is for including additonal libraries
663 needed for dynamic linking.
664 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
665 instead of PLUGIN/guile.libs.
667 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
669 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
671 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
672 occurrences of the given element from the list, not just the
673 first. This is how the Emacs Lisp functions behave, how the
674 analogous Common Lisp functions behave, and (I believe) how the
675 older Maclisp functions worked. I realize that this change may
676 break code, but it seemed better to break it before the Guile
679 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
680 Their prototypes were already present in gc.h, but they weren't
682 (scm_init_storage): Initialize scm_protects.
683 * root.c (scm_protects): New element of scm_sys_protects.
685 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
687 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
689 * libguile.h: Added #include "libguile/net_db.h".
691 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
692 30 change. That file is only meant for communication between the
693 configuration process and load.c. If code linked against libguile
694 wants to get at the paths mentioned in libpath.h, it can call
695 functions declared in load.h.
697 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
699 * libguile.h: Removed #include "libguile/fdsocket.h"
701 * net_db.c: Added #include <sys/socket.h>.
703 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
705 * filesys.c (scm_input_waiting_p): use select in preference to
706 FIONREAD, since the latter doesn't detect EOF.
707 Throw error if neither select nor FIONREAD available.
709 * socket.c (scm_connect): take a port, not a fd object.
710 (scm_fill_sockaddr): throw an error if fam is not recognised.
711 (scm_bind): use scm_fill_sockaddr.
712 (scm_listen): take a port, not a fd object.
713 (scm_accept): take and return a port. return #f in the car if
715 (scm_sock_fd_to_port): new procedure.
716 (scm_socket): use scm_sock_fd_to_port.
717 (scm_addr_vector): throw error if unrecognised address type.
718 take an extra argument with the calling procedure name.
719 (scm_getsockname): take a port. return #f if address can't be got.
720 (scm_getpeername): take a port. return #f if address can't be got.
721 (scm_recvfrom): take a port. return #f for address component if can't
723 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
724 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
726 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
728 * throw.c (scm_internal_catch): Make body funcs and handler funcs
729 use separate data pointers, to allow them to be designed
730 independently and reused.
731 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
732 Renamed from catch_body, catch_handler, and uncaught_throw; made
734 (struct scm_catch_body_data): Renamed from catch_body_data; moved
736 (scm_catch): Use the above.
737 (scm_throw): Don't bother printing a message for an uncaught
738 throw; we establish a default handler in init.
739 * throw.h (scm_internal_catch): Prototype updated.
740 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
742 (struct scm_body_thunk_data): New structure, used as data
743 argument to scm_body_thunk.
744 * init.c (struct main_func_closure): New structure, packaging up
745 the data to pass to the user's main function.
746 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
747 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
748 scm_internal_catch to establish a catch-all handler, using
749 scm_handle_by_message. This replaces the special-case code in
751 (invoke_main_func): Body function for scm_internal_catch; invoke
752 the user's main function, using the main_func_closure pointer to
753 decide what to pass it.
754 * root.c (struct cwdr_body_data): Remove handler_proc member.
755 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
756 (cwdr_handler): Removed.
758 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
760 * socket.h (SCM_P): update bind prototype.
761 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
763 (scm_socket): return a port, not a file descriptor object.
764 include "fports.h" and <unistd.h>
765 (scm_bind): take a port, not a file descriptor object.
766 take an extra argument for address args.
768 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
769 INADDR_NONE, INADDR_LOOPBACK.
771 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
773 * init.c: include net_db.h and not fdsocket.h.
774 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
776 * Makefile.am: corresponding changes.
777 * socket.h: renamed from fdsocket.h, fix names.
778 * net_db.h: renamed from socket.h, fix names.
779 * socket.c: renamed from fdsocket.c.
780 remove _sys from procedure names.
781 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
782 add "socket" to features list.
783 * net_db.c: renamed from socket.c.
784 remove _sys from procedure names.
785 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
786 add "net-db" to features list.
787 include "net_db.h". don't include <sys/socket.h> or
790 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
792 * tags.h (scm_tags): Removed comma at end of last enumerator.
794 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
796 Don't use GCC extensions to allocate space for debugging frames.
797 (Here he goes again! Why do we put up with this?!)
798 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
799 an scm_debug_info structure, not an in-line array of them. Add
800 'info' member, to say how many vect elements we've used, for eval
802 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
803 a new variable debug_info_end to mark the end of vect, instead of
804 the address of the 'info' pointer itself.
805 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
806 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
807 (SCM_APPLY): Explicitly allocate space for debug.vect.
808 * debug.c (scm_m_start_stack): Same, for vframe.vect.
809 * stacks.c: Adjusted for new debug frame structure.
810 (RELOC_INFO, RELOC_FRAME): New macros.
811 (stack_depth, read_frames): Use them, and new scm_debug_frame
812 element 'info', instead of magically knowing that eval frames have
813 an info pointer sitting after vect.
814 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
816 (scm_init_stacks): Formatting tweaks.
818 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
820 Give GCC more control flow information, so it can be sure that
821 variables aren't used uninitialized.
822 * error.h (scm_error, scm_syserror, scm_syserror_msg,
823 scm_sysmissing, scm_num_overflow, scm_out_of_range,
824 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
825 scm_misc_error): Tell GCC that these functions never return.
826 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
827 out the field type, call abort if SCM_ASSERT returns, to placate
829 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
830 scm_wta ever returns. We can't handle this case anyway, and this
831 gives the optimizer more information.
832 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
833 scm_wta ever returns.
835 In some cases, the code is fine, but GCC isn't smart enough to
836 figure that out; this usually happens when one variable is only
837 initialized and used when a particular condition holds true, and
838 we know that condition will never change within a given invocation
839 of the function. In this case, we simply initialize the variables
840 to placate the compiler, hopefully to a value which will cause a
841 crash if it is ever actually used.
842 * print.c (scm_iprin1): Initialize mw_pos.
843 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
844 * throw.c (scm_ithrow): Initialize dynpair.
845 * unif.c (scm_uniform_vector_ref): Initialize cra.
846 * struct.c (init_struct): Initialize prot.
847 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
849 * strports.c (scm_eval_0str): Don't return uninitialized garbage
850 if EXPR contains no expressions.
852 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
854 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
855 cause an infinite loop (???). So much for the algebraic
856 equivalency of variable-sized arrays and alloca...
858 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
860 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
861 a SCM boolean, not a C boolean.
863 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
865 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
866 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
867 rules for raising scm_mtrigger. Previously, unfortunate but not
868 unlikely circumstances could result in almost constant invokation
869 of the gc. Now, this situations should be less likely, but they
870 are not prevented completely.
872 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
874 * numbers.c (scm_fuck): Procedure removed; looks like old test
876 * numbers.h: Prototype removed.
878 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
880 * debug.h (scm_debug_frame): Change `vect' member from an in-line
881 array to a pointer, to match my Nov 21 change in eval.c.
883 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
885 * libguile.h: Added #include "libguile/backtrace.h", #include
888 * strings.c (scm_string scm_make_string scm_string_ref
889 scm_string_set_x scm_string_equal_p scm_string_append):
890 Bugfix according to scm patch from Aubrey Jaffer:
891 Corrected long-standing
892 (not (eqv? (integer->char 128)
893 (string-ref (make-string 1 (integer->char 128)) 0)))
894 bug found by John Kozak <jk@noontide.demon.co.uk>.
896 * strports.c, strports.h: Make scm_eval_0str return the value of
897 the last expression evaluated (previously, it returned void).
899 * strports.c, strports.h: New function: scm_read_0str. Does what
902 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
904 * simpos.c (scm_getenv): return #f if string can't be found in the
905 environment instead of throwing an exception, for compatibility
906 with numerous other systems.
908 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
910 * Makefile.am (.c.x): Use guile-snarf.
911 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
913 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
915 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
917 * backtrace.c (scm_display_error_message): Made non-static, and
918 renamed from display_error_message.
919 * backtrace.h (scm_display_error_message): Added extern decl.
920 * throw.c (uncaught_throw): Use it to display the error message.
922 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
924 * inet_aton.c: Use #if 0, not #ifdef 0.
926 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
928 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
929 to convert the returned value.
930 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
933 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
935 Add new interface to catch/throw, usable from C as well as
937 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
938 (scm_internal_catch): New function, replaces...
939 (scm_catch_apply): Deleted.
940 * throw.c (scm_catch_apply): Deleted; replaced with a more general
941 mechanism which is a bit more code, but can be used nicely from C
942 and implement the Scheme semantics as well.
943 (scm_internal_catch): This is the replacement; it's named after
944 the analogous function in Emacs.
945 (scm_catch): Reimplemented in terms of the above.
946 (struct catch_body_data, catch_body, catch_handler): New
947 functions, used by scm_catch.
948 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
949 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
950 support for new cwdr.
952 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
955 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
957 * acconfig.h: Added DYNAMIC_LINKING symbol.
958 * configure.in: Add option and checks for dynamic linking.
959 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
960 dynl.h: New files for dynamic linking support.
961 * Makefile.am (libguile_a_SOURCES):
963 (modinclude_HEADERS): Added "dynl.h".
964 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
966 * init.c (scm_boot_guile_1): Call
967 scm_init_dynamic_linking to initialize dynamic linking support.
969 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
971 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
972 (as we Schemers say). It needs to be global, so that I can tweak
973 it for the proper operation of unexec.
974 (scm_boot_guile_1_live): New variable, see above.
976 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
978 * guile-snarf.sh: Removed.
979 * PLUGIN/guile.libs: Added dependency for -lm.
980 * acinclude.m4: Renamed from aclocal.m4.
981 * PLUGIN/greet: Removed.
982 * Makefile.am, aclocal.m4: New files.
983 * configure.in: Updated for Automake.
985 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
987 * eval.c (scm_definedp): Use top_level_lookup_closure_var
988 and not top_level_lookup_thunk_var.
990 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
992 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
994 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
996 * eval.c (scm_definedp): Incompatibly changed to be a builtin
997 Scheme function, instead of syntax. Single argument is now a
1000 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1002 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
1003 scm_ra_divide): Properly terminate statements passed as arguments
1004 to IVDEP macros. (Thanks to Bernard Urban.)
1006 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
1007 with non-constant sizes. (Thanks to Bernard Urban.)
1009 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1011 It's an "eval closure", not an "eval thunk." A thunk is a
1012 function of no arguments.
1013 * root.h (struct scm_root_state): Renamed
1014 top_level_lookup_closure_var from top_level_lookup_thunk_var.
1015 (scm_top_level_lookup_closure_var): Renamed from
1016 scm_top_level_lookup_thunk_var.
1017 * root.c (mark_root): Uses changed.
1018 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
1019 * init.c (scm_start_stack): Uses changed.
1020 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
1021 Change scheme-visible name to *top-level-lookup-closure* from
1022 *top-level-lookup-thunk*.
1024 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
1026 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
1027 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
1029 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
1031 * gc.c (struct scm_heap_seg_data): Doc fixes.
1033 * gc.c (scm_gc_sweep): Empty all segments' freelists before
1034 sweeping. Then, prepend each segment's free cells to its
1035 freelist, rather than wiping out the old value. (Thanks to Marius
1038 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
1039 scm_check_freelist, scm_debug_newcell): New functions and
1040 variables, for debugging freelist problems.
1041 * pairs.h (SCM_NEWCELL): New debugging version added.
1042 * gc.h (scm_debug_newcell): Added extern declaration, used by
1043 debugging version of SCM_NEWCELL.
1045 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1047 On some systems <libc.h> conflicts with <unistd.h>, and should not
1048 be #included at all.
1049 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
1050 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
1051 * configure.in: Call it.
1052 * posix.c, filesys.c: Use its results to decide whether or not to
1054 * configure, scmconfig.h.in: Rebuilt with autoconf and
1057 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1059 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
1060 pointer to the stdio stream before calling scm_setbuf0, so the
1061 latter will be able to retrieve it. I'm surprised this didn't
1062 segfault earlier. (Thanks to Christopher Lee.)
1064 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1066 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
1069 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1071 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
1072 number of stack narrowing specifier pairs. The first specifier in
1073 a pair controls inner border, the second the outer border. A
1074 number means cut that number of frames, a procedure object means
1075 cut until that object is found in operator position in a frame.
1077 * root.c (cwdr): Bugfix.
1079 * read.c: Recording of positions disabled by default.
1081 * procs.c (scm_closure_p): New function.
1083 * posix.c (scm_tmpnam): New function.
1085 * load.c: Added #include "throw.h".
1086 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
1089 * load.c, load.h (scm_read_and_eval_x): New function.
1091 * eval.c: Renamed debug option "deval" to "debug".
1093 (scm_eval_x): `eval!' is no longer accessible from the scheme
1094 level. Motivation: We can't allow operations which introduce
1095 glocs into the scheme level. Guile's type system can't handle
1096 these as data. Use `eval' or `read-and-eval!' as replacement.
1098 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
1099 SCM_CONSP since this is a macro!; Set vframe.prev to
1100 scm_last_debug_frame instead of 0. In this way we can look
1101 "above" the virtual start stack frame if we wish.
1102 (scm_debug_hang): New function: Useful for debugging Guile in
1103 certain tricky situations. Will probably be removed later...
1105 * debug.h: Changed semantics of debug option "backtrace". This
1106 option now only indicates whether we want automatic backtrace at
1109 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1111 * ports.c: #include "filesys.h"
1112 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
1114 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
1115 Motivation: This is system specific code which is related to file
1116 I/O. It also may use select. Added code by Gary Houston to
1117 detect presence of character in stdio buffers.
1119 * libguile.h: #include "libguile/libpath.h"
1121 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
1122 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
1123 SCM_SITE_DIR; Install libpath.h among the other include files.
1125 * load.c, load.h (scm_sys_package_data_dir): New function.
1127 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1129 * stacks.h: Bugfix: Don't use tail-array length field as stack
1130 length field! This screwed GC.
1132 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1134 * _scm.h: Added #ifndef around definition of macros min and max.
1136 * __scm.h: Added hooks for threads to plugin to in ints protection
1137 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
1138 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
1139 the main code in these macros duplicated and spread over multiple
1140 files. Renamed SCM_THREADS_SWITCHING_CODE ->
1141 SCM_THREAD_SWITCHING_CODE.
1143 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
1145 * snarf.h: New file.
1146 * guile-snarf.sh: New file.
1147 * Makefile.in (inner_h_files): Added snarf.h
1148 (ancillary, install, uninstall, distclean): Added actions for
1150 (.c.x): Use guile-snarf.
1151 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
1152 (gen_c_files): Note that these depend on guile-snarf.
1153 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
1154 now in "snarf.h". Added #include "snarf.h" to get them.
1155 * libguile.h: Added #include "snarf.h".
1156 (Patches applied and tweaked by Jim Blandy.)
1158 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1160 * socket.c: Use K&R style declaration for 'close'; the GNU coding
1161 standards suggest against providing prototypes for system
1162 functions. Thanks to Greg Troxel.
1164 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1166 * strports.c (scm_eval_0str): New function.
1167 #include "read.h", to get prototype for scm_read.
1168 * Makefile.in (strports.o): Update dependencies.
1169 * strports.h: New prototype.
1171 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
1172 scheme name from "int?" to "integer?". It seems to do the job.
1173 * numbers.h: Rename prototype too.
1174 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
1177 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
1178 scm_num_eq_p): Rename these according to R4RS conventions: call
1179 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
1180 to making libguile R4RS compliant without ice-9...
1182 * load.c (scm_sys_search_load_path): Search for files under all
1183 extensions listed in the %load-extensions variable. If FILENAME
1184 is absolute, return it unchanged, without searching the load path.
1185 (scm_loc_load_extensions): New variable, pointing to
1186 %load-extensions' value cell.
1187 (scm_init_load): Initialize it, and the value it points to.
1188 (scm_primitive_load_path): Improve error reporting.
1190 * load.c (scm_loc_load_hook): New variable, pointing to value cell
1191 of new Scheme variable %load-hook.
1192 (scm_primitive_load): Apply %load-hook to filename.
1194 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
1196 * configure.in: add tests for figuring out whether buffered data
1197 is available in a FILE structure, which is needed by char-ready.
1199 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
1202 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
1203 exceptions using misc_error instead of syserror. It seems a bit
1204 odd to throw an exception if a string can't be found in the
1205 environment, but it's consistent with open-file, stat etc.
1206 (simpos.h): remove sys_ from getenv.
1208 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
1209 occurs, throw an error instead of returning errno. Return value
1211 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1213 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1215 * filesys.c (scm_stat2scm): derive file type and permissions from
1216 the stat mode and append them to the returned vector.
1217 There isn't much overhead in doing this and it avoids the need to
1218 work with S_IRUSR et al. in Scheme.
1219 Define symbols scm_sym_regular etc.
1220 (scm_init_filesys): don't intern S_IRUSR etc.
1222 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1223 and s_primitive_load_path.
1225 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1227 * error.h: don't declare error symbols. prototype for scm_misc_error.
1229 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1232 * error.c: use SCM_SYMBOL to set up error keys.
1233 scm_misc_error: new procedure.
1235 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1237 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1238 between `#!' and `!#' is ignored.
1239 (skip_scsh_block_comment): New function.
1241 * feature.c (scm_set_program_arguments): New argument, FIRST.
1242 * feature.h: Update prototype.
1243 * init.c (scm_boot_guile_1): Pass new argument to
1244 scm_set_program_arguments.
1246 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1248 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1249 (scm_boot_guile): Call scm_set_program_arguments here, later than
1250 the old initialization.
1252 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1253 initialization procedure.
1254 - Delete in, out, err arguments; there are other perfectly good
1255 ways to override these when desired.
1256 - Delete result argument; this function shouldn't ever return.
1257 - Rename init_func argument to main_func, for less confusion.
1258 - Delete boot_cmd argument; main_func is more general.
1259 -Add 'closure' argument, to help people pass data to main_func
1260 without resorting to global variables.
1261 - Abort if reentered; don't bother returning an error code.
1262 - Call scm_init_standard_ports to set up the default/current
1263 standard ports; no need to pass them to scm_start_stack.
1264 - Remove code to evaluate the boot_cmd, and start the repl; let
1265 the user do something like that in main_func if they want.
1266 - Remove code to package up a return value; main_func can do any
1268 - Call exit (0), instead of returning.
1269 (scm_start_stack): Don't initialize the I/O ports here; that's
1270 weird. Delete in, out, err arguments. Move guts to
1271 scm_init_standard_ports, scm_stdio_to_port.
1272 (scm_init_standard_ports): New function, to set up current and
1273 default standard ports.
1274 (scm_start_stack, scm_restart_stack): Make these static.
1275 * init.h (scm_boot_guile): Adjust declaration.
1276 (scm_start_stack, scm_restart_stack): Remove externally
1277 visible declarations for these.
1278 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1280 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1281 written out several times in scm_start_stack.
1282 * fports.h: New declaration for the above.
1284 * feature.c (scm_set_program_arguments): New function.
1285 * feature.h: New declaration for the above.
1287 * ports.c: Formatting tweak.
1289 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1291 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1292 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1293 for obtaining the address of a car or cdr field. Motivation:
1294 &SCM_CXR make assumptions about the internal structure of the
1297 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1298 Motivation: see SCM_CXRLOC.
1300 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1301 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1302 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1303 Motivation: Safer use. Some other macros are defined in terms of
1304 these operations. If these are defined using the SCM_SETCXR
1305 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1306 to inefficiency and an <e1> with side-effects could potentially
1307 break. Also, these particular operations are heavily utilized in
1308 the garbage collector. In unoptimized code there will be a
1311 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1312 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
1313 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
1314 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
1315 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
1316 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1317 vports.c: Cleaned up use of pairs: Don't make any special
1318 assumptions about the internal structure of selectors and
1319 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1320 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1321 (Among other things, this change makes it easier to build Guile
1322 with certain compilers which have problems with casted lvalues.)
1324 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1326 * stacks.c: Improve selection of relevant stack frames when making
1327 a stack object. Introduce one level of indirection in the stack
1328 object to make it possible to "narrow" to a certain region of the
1329 stack. This facilitates making use of more clever algorithms (not
1330 implemented) for selecting relevant frames and gives a cleaner
1331 design since selection of frames can be done independently of
1332 extraction of frames from the real stack.
1333 (scm_stack_id): Also take #t as argument which means look at
1336 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1337 Turn n_tail into an integer directly representing current number
1338 of frames in stack. Add field tail.
1340 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1342 * debug.c (scm_make_memoized): Made it available at scheme level.
1343 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1344 SCM_NIMP before applying heavier predicates in argument checking.
1345 (scm_local_eval): Also take memoized object as argument.
1347 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1348 aren't created with zero length, but should such a strange
1349 creature suddenly turn up...
1351 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1353 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1354 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1356 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1358 * variable.c (scm_make_variable): Make the name hint optional, as
1360 (anonymous_variable_sym): Renamed from variable_sym. All uses
1363 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1364 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1365 of scm_primitive_load_path was also changed to
1366 "primitive-load-path", from "%try-load-path". Callers changed.
1367 We'd like to respect the convention that a function named
1368 "try-mumble" should behave just like the function called "mumble",
1369 but return #f instead of signalling some error.
1370 * load.h: Rename prototypes.
1372 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1374 * print.c (make_print_state, grow_print_state), print.h: Modified
1375 the print state representation: Don't use a tail array for
1376 recording of circular references. Resizing of the print state
1377 structure invalidates the print state pointer. To avoid passing
1378 around an indirect print state reference to all printing
1379 functions, we instead let the print state reference a resizable
1382 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1384 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1385 Don't crash when passed an improper list terminated by a
1386 non-immediate value.
1388 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1390 Allocate data for structures on an eight-byte boundary, as
1391 required by the tagging system.
1392 * struct.c (alloc_struct): New function.
1393 (scm_make_struct, scm_make_vtable_vtable): Call it.
1394 * struct.h (scm_struct_n_extra_words): Bump to 3.
1395 (scm_struct_i_ptr): New "field".
1396 * gc.c (scm_gc_sweep): When we need to free the data, use the
1397 information stored by alloc_struct to find the beginning of the
1398 block allocated to the structure, so we can free it.
1400 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1402 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1405 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1406 (scm_debug_info): New member: id.
1408 * stacks.c: Stacks are now represented as structs; Stacks have an
1409 id given to them by `start-stack'.
1410 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1412 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1413 Changed stack representation.
1415 * debug.c (scm_procedure_name): Try procedure property `name' for
1416 compiled closures aswell.
1418 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
1420 * eval.c: scm_i_name moved to gsubr.c
1421 (scm_m_define): Record names of all kinds of procedure
1422 objects. (Earlier, only closures were recorded.)
1424 * procprop.h: Added declaration of scm_i_name.
1426 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1427 (scm_make_gsubr): Record names of compiled closures.
1429 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1431 * debug.c, debug.h: Removed obsolete code.
1433 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1434 stacks.c: Renamed regs --> scm_contregs.
1436 * print.c (scm_free_print_state): Cleanup print state before
1437 returning it to pool. It is better to do it here than in
1438 scm_prin1 since scm_prin1 is called often.
1440 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1441 s_set_source_property_x): Check that first argument is a pair or a
1444 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1445 scm_i_line, scm_i_column and scm_i_breakpoint global.
1447 * init.c: Added #include "backtrace.h" and #include "stacks.h".
1448 (scm_boot_guile_1): Added calls to scm_init_backtrace and
1451 * debug.h: Added debug object smob declaration and macro
1454 * configure.in: Build with backtrace.o and stacks.o if debug
1457 * Makefile.in: Added entries for new files: backtrace.c,
1458 backtrace.h, stacks.c and stacks.h.
1460 * symbols.c (scm_sym2ovcell): Fixed documentation.
1462 * _scm.h (min, max): Added.
1464 * async.c: Moved `min' macro to _scm.h.
1466 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1467 SCM_BACKTRACE_INDENT.
1469 * eval.c: Added new debug options `maxdepth' and `indent'.
1471 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
1473 * print.h: Added selector SCM_PRINT_STATE.
1475 * print.c: New functions: scm_make_print_state,
1476 scm_free_print_state.
1478 * print.h: Added declarations for scm_make_print_state,
1479 scm_free_print_state.
1481 * debug.c (scm_m_start_stack): New acro.
1483 * debug.h: Small cleanup.
1485 * init.c (scm_boot_guile_1): Moved scm_init_debug below

1513 More prototype-related changes from Marius Vollmer:
1514 * gdb_interface.h: Wrapped header file in #ifdef/#endif
1515 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
1516 * ports.h (ptobfuns): Added prototypes. This means some casting in
1518 * fports.c: Added casts for initializations, since the functions
1519 are defined to take FILE * as their stream argument, not SCM.
1520 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
1521 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
1522 to `char *str_data' to conform to prototype.
1524 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1526 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
1528 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
1530 * stime.c, stime.h: use SCM_P method.
1532 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1534 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
1535 be given at least two arguments. Insist that lst's last element
1536 be a list, but don't make any requirements of its predecessors.
1538 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1540 * eval.c (scm_nconc2last): Revert last change; there seems to be
1541 other stuff going on here.
1543 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1545 * eval.c (scm_nconc2last): Make sure that each element of lst
1546 (which is a list of argument lists, except for the tail) is a
1547 proper list, i.e., finite and terminated by '().
1549 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1551 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
1554 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
1555 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
1558 * vectors.c (scm_make_vector): Fill vectors with the undefined
1559 value, to help make Guile Scheme code more portable to other
1562 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
1563 * symbols.h, tags.h: Doc fixes.
1565 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
1567 * async.c (scm_take_signal): Doc fixes.
1569 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
1571 * numbers.c (scm_divbigint): When the remainder is zero, we don't
1572 want to subtract it from the modulus; we just want to leave it
1575 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
1577 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
1580 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
1582 * throw.c (scm_catch_apply): Finished implementation of
1585 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
1587 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
1589 (scm_init_filesys): set "i/o-extensions" feature.
1592 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
1594 * Makefile.in (root.o): Correct dependencies.
1596 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
1598 * Makefile.in: Added dependency entry for root.o.
1600 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
1601 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
1603 * init.c (scm_start_stack): Set initial root continuation number
1606 * procs.c: New function: scm_thunk_p.
1608 * procs.h: Added declarations of scm_thunk_p.
1610 * root.c: Renamed `call-with-new-root' -->
1611 `call-with-dynamic-root'.
1612 (cwdr): Removed allocation of new root state. This should be done
1613 separately by use of scm_make_root.
1614 (scm_apply_with_dynamic_root): New function: Does what it
1615 sounds like. Needed when spawning threads.
1617 * root.h: Added member last_debug_frame to root state.
1618 Added #include "libguile/debug.h"
1620 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
1621 arguments. The motivation is that code in root.c needs catch
1622 functionality, and we want to avoid code duplication.
1623 New functions: scm_catch, scm_lazy_catch. These are wrappers for
1624 scm_catch_apply. scm_lazy_catch is intended to introduce catch
1625 handlers that run without popping the stack into the dynwind
1628 * throw.h: Added prototypes for scm_catch_apply and
1631 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1633 * root.h (scm_root, scm_set_root): Decouple thread support details
1634 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
1635 SCM_SET_THREAD_LOCAL_DATA.
1637 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
1638 and tortoise scanning loop.
1640 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
1642 * Makefile.in: Rebuild dependencies.
1644 * libguile.h: #include "libguile/print.h" before "smob.h", since
1645 the latter uses the print_state structure.
1647 * throw.c (scm_ithrow): Use the correct variable when checking to
1648 see if a given element of scm_dynwinds is a valid catch.
1650 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
1651 structure, abort; don't just silently ignore the garbage.
1653 * _scm.h: #include "print.h" here, since it seems to be used just
1655 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
1656 strports.c, unif.h: Don't #include "print.h".
1658 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1660 * feature.h (scm_loc_features): Removed external declaration.
1661 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
1663 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1665 * feature.c (scm_init_feature): Added threads feature (needs to be
1666 initialized here, since features doesn't exist when
1667 scm_init_threads is called).
1669 * libguile.h: Added #include "libguile/../threads/threads.h".
1670 (This is a kludge to get thread support working. This should be
1673 * configure.in, acconfig.h: Added flags for thread support.
1675 * scmsigs.c: Define `signal' to be `pthread_signal' if using
1678 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
1679 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
1682 * _scm.h: Added conditional #include "threads.h"
1684 * __scm.h (SCM_ASYNC_TICK): Added call to macro
1685 SCM_THREADS_SWITCHING_CODE.
1687 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
1688 allocate the basic dynamic root object.
1689 (scm_boot_guile): Added call to scm_init_root.
1691 * root.c, root.h: Added root smob.
1692 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
1693 functions: Implements dynamic roots mostly according to spec in
1694 SCM manual. Main difference is that the second argument is a
1695 throw handler rather than an error "thunk".
1697 * root.h: Added declaration of scm_init_root.
1699 * root.c: Added #include "genio.h", #include "smob.h", #include
1700 "pairs.h", #include "throw.h", #include "dynwind.h", #include
1702 (scm_init_root): Added #include "root.x".
1704 * throw.c: Added #include "stackchk.h"
1705 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
1706 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
1707 can be used in scm_call_with_new_root; Added reenabling of stack
1708 checking when catching a throw.
1710 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
1712 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
1714 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
1715 element is not found, as per R4RS.
1717 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1719 * list.c: Doc fixes throughout.
1721 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1723 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
1724 declare the char * to be const. Avoids a warning in rgx.c.
1726 * ports.h: spelling fix.
1728 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
1731 * load.c (scm_sys_try_load_path): throw an error if file not found
1732 (like it says it in NEWS).
1734 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1736 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
1737 PROPS slot to '(), not #f; it's an empty alist.
1739 * throw.h, throw.c: Use SCM_P instead of #if hair.
1741 Remove special support for uncaught throws; see throw.c for
1743 * throw.c (uncaught_throw): New function.
1744 (scm_ithrow): Call uncaught_throw if we don't find a throw
1745 target; don't mess with scm_bad_throw_vcell.
1746 (scm_bad_throw_vcell): Variable deleted.
1747 (scm_init_throw): Don't initialize it.
1749 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
1752 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1754 * numbers.c (scm_istr2int): If the number is short (as most
1755 numbers are), just call scm_small_istr2int to deal with it.
1756 (scm_small_istr2int): New function, created by un-#ifdefing the
1757 non-bignum version of scm_istr2int and renaming it.
1759 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
1761 * load.c (scm_sys_try_load): don't check whether value returned
1762 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
1763 Change the Scheme name from %try-load to primitive-load.
1765 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
1766 Can avoid passing a message, allowing it to be derived in the
1767 error handler (e.g., if we want to throw to the key both from
1770 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
1772 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
1773 references now have a new appearance which is more compact and
1774 also gives a clue about what the target of the reference is.
1775 By setting parameters in the print state, more fancy printing can
1776 be achieved. This is used by the (not yet commited) backtrace
1779 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
1781 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
1784 * print.c: Added #include "struct.h". Removed function
1787 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
1788 scm_iprin1. Removed prototype for scm_prlist.
1790 * arbiters.c (prinarb),
1791 async.c (print_async),
1792 debug.c (prindebugobj, prinmemoized),
1793 eval.c (prinprom, prinmacro),
1794 filesys.c (scm_fd_print, scm_dir_print),
1796 mallocs.c (prinmalloc),
1797 numbers.c, numbers.h (scm_floprint, scm_bigprint),
1798 smob.h (scm_smobfuns),
1799 srcprop.c (prinsrcprops),
1801 unif.c, unif.h (scm_raprin1, rapr1),
1802 variable.c (prin_var): Changed argument `int writing' to
1803 `scm_print_state *pstate'.
1805 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
1806 that it will be called before scm_init_print.
1808 * print.c (scm_prin1): Print states are now allocated when calling
1809 scm_prin1 and then passed around to all printing functions as an
1810 argument. A cache `print_state_pool' enables reuse of print
1812 (scm_make_print_state): New function.
1813 (scm_iprin1): Adaption to print states.
1814 (scm_iprlist): An initial "hare and tortoise" scan brings down
1815 time complexity to O (depth * N). (Better time complexity will be
1816 achieved when the printing code is completely rewritten.)
1818 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1820 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
1821 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
1822 it gets done whether or not the cache variable has a value.
1824 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
1826 Distinguish #f and ().
1827 * __scm.h: #undef SICP.
1828 * pairs.h (SCM_EOL): Delete this definition, equating it with
1830 * tags.h (SCM_EOL): Give it a new definition here; I think I found
1831 the value it used to have. Doc fixes, too.
1833 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
1835 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
1836 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
1837 Lord's implementation of structs, allowing for tail arrays as
1838 described in the manual. Also fixed some bugs. (Both the interface
1839 and the implementation should be improved.)
1841 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
1843 * print.c, print.h: Closures now print like #<procedure foo (x)>.
1844 People who whish to see the source can do `(print-enable 'source)'.
1845 Removed #ifdef DEBUG_EXTENSIONS.
1847 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1849 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
1850 integer (assuming for now accepting an integer is a good thing).
1852 * error.c, fports.c: replace use of %S in lgh_error args with %s.
1853 %S will be used instead for write'ing arguments.
1855 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
1856 asserts. fix a few other asserts.
1857 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
1858 scm_uniform_vector_ref, scm_array_set_x,
1859 scm_dimensions_to_unform_array): change args in
1860 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
1861 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
1862 scm_substring_fill_x): likewise.
1863 gsubr.c (scm_gsubr_apply): likewise.
1864 eval.c (SCM_APPLY): likewise.
1866 * eval.c (4 places): replace scm_everr with lgh_error or
1869 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
1870 scm_memory_error): new procedures.
1871 scm_everr: deleted. can use scm_wta, dropping first two args.
1872 scm_error: convert NULL subr to SCM_BOOL_F.
1874 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
1877 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
1880 * error.c, error.h: new error keys: scm_arg_type_key,
1881 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
1883 scm_wta: reimplement using lgh_error instead of scm_everr.
1885 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
1887 * gdbint.c: scm_lread now has one more argument.
1889 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
1890 scm_port_\1; Added mutator scm_set_port_filename_x (used when
1891 loading source from non-file ports, which, e. g., happens when
1892 using the Emacs interface).
1894 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
1897 * read.c: Added code for recording of positions of source code
1898 expressions; New functions: recsexpr, scm_lreadrecparen;
1899 _scm_make_srcprops --> scm_make_srcprops
1900 (scm_flush_ws): Removed updating of positions counters. This work
1901 is already done by scm_gen_getc
1903 * read.h: Added prototype for scm_lreadrecparen
1905 * print.c: Added #include "alist.h"
1907 * eval.c: Added #include "hash.h"
1909 * eq.c: Added #include "ramap.h"
1911 * options.c: Documentation fixes.
1913 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
1914 (scm_init_srcprop): Adjusted size of initial source-whash. Name
1915 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
1916 --> scm_make_srcprops
1918 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
1919 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
1920 function calls in the definition of the whash access macros.
1922 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
1924 * init.c (scm_boot_guile): Add level of indirection to
1925 scm_boot_guile_1() to ensure that stack base pointer is properly
1926 initialized. There was no guarantee that variable i was the
1927 highest/lowest variable on stack (i.e. the call frame of
1928 scm_boot_guile was not completely protected from gc).
1930 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
1932 * ports.h (scm_port_table): put back file_name, it will be used to
1933 support debugging. Undo related changes in fports.c, ioext.c,
1936 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1938 * ports.h (scm_port_table): remove file_name member for now, it seems
1940 * fports.c (scm_open_file): don't set file_name in PTAB.
1941 (prinfport): don't use file_name in PTAB.
1942 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
1943 * ports.c (scm_add_to_port_table): don't intialize file_name.
1944 (scm_port_file_name): remove for now.
1945 * gc.c (scm_gc_mark): don't mark PTAB file_name.
1947 * fports.h (scm_mkfile): prototype deleted.
1948 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
1950 * debug.c, unif.c: use scm_out_of_range instead of
1951 wta for range errors (ASSERT still needs work).
1953 * error.c, error.h (scm_out_of_range): new procedure.
1955 * error.c, error.h (scm_out_of_range_key): new key.
1957 * posix.c (scm_sync): #else was missing.
1959 * error.c, error.h: append _key to names scm_num_overflow and
1962 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
1963 of consing an empty list.
1964 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
1965 of macros, saves code and string space.
1966 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
1967 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
1968 lower case. Rename scm_syserror_m to scm_syserror_msg.
1969 error.h: prototypes for new procedures.
1971 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
1973 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
1975 * error.c, error.h: setup scm_num_overflow key.
1977 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
1978 Remove definition of SCM_OVSCM_FLOW.
1980 * fports.c (scm_open_file): use SCM_SYSERROR_M.
1982 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
1983 explicit message and args.
1985 * error.c, error.h, __scm.h: change system_error_sym to
1988 * error.c (system_error_sym): remove leading %% from the Scheme name
1991 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
1993 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1995 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
1996 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
1997 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
1998 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
1999 renamed. (These were introduced by unsupervised name
2002 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2004 * print.c: Added code for detection of circular references during
2005 printing. (init_ref_stack, grow_ref_stack): New functions. Added
2006 a hook for printing of closures (accessible via print options).
2007 This leads to a split of calls to scm_iprin1 into two classes:
2008 elementary print operations (e. g. the code which prints a smob)
2009 still use scm_iprin1 while top level calls (like scm_display) use
2010 scm_prin1. scm_prin1 begins by clearing the data structure used
2011 to record reference information.
2013 * print.h: Added declarations of scm_prin1 and scm_prlist.
2015 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
2017 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
2019 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
2021 * error.c (err_head): scm_iprin1 --> scm_prin1
2023 * debug.c: Adjusted header comment.
2027 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2029 * strerror.c: Doc fix.
2031 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2033 * gdbint.c (gdb_read): Now possible to run during GC.
2034 (unmark_port, remark_port): New functions.
2036 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
2038 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
2039 of allocating a new string object. Also, increase size by
2040 the factor 2 instead of 1.5.
2042 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
2044 * __scm.h (SCM_P): Corrected to run under traditional C.
2046 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
2049 * async.c: Calls to scm_sysintern corrected.
2051 * async.h (scm_async_clock): Redundant declaration removed.
2053 * continuations.c (scm_dynthrow): Redundant declaration removed.
2055 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
2056 Definition typos corrected.
2058 * debug.h: Missing declarations of functions in debug.c added
2061 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2062 Missing declarations to functions in eval.c added.
2064 * filesys.c: Possibly uninitialized variable rv.
2066 * gc.h (scm_object_addr, scm_unhash_name): Missing
2067 declarations of functions defined in gc.c added.
2069 * genio.c: Possible typos str_data -> wstr_data. ???
2071 * genio.c: Possibly unintended shadowing of local variable
2072 `int c' (gotos out of scope of inner `c'). ???
2074 * init.c: Uninitialized `SCM last' may be used.
2076 * ioext.h: (scm_sys_isatty_p): Typo.
2078 * list.h (scm_list_head): Missing prototype for function in
2081 * numbers.c (scm_two_doubles): Changed from extern to static
2082 (is used only within numbers.c).
2084 * numbers.h: Repeated declarations removed.
2086 * ports.h (scm_close_all_ports_except): Declaration for the
2087 function defined in ports.c added.
2089 * posix.h: Missing declarations added.
2091 * procs.h (scm_make_subr_opt): Missing declaration added.
2093 * socket.h (scm_sys_gethost): Missing declaration added.
2095 * socket.h: Redundant declarations removed (they are in fdsocket.h).
2097 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
2098 Missing declarations added.
2100 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
2102 * struct.c: Uninitialized variable `SCM answer' may be used.
2104 * unif.c (l2ra): Declaration prototype.
2106 * unif.c (scm_array_equal_p): Dummy definition removed (it is
2107 defined in ramap.c).
2109 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
2110 Redundant declarations removed (they are in ramap.h).
2112 * variable.h (scm_make_udvariable,
2113 scm_make_undefined_variable): Declaration corrected to
2114 correspond variable.c.
2116 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
2117 Missing declarations added.
2119 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
2121 * Makefile.in (distclean): Don't forget to delete fd.h.
2123 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2125 * fd.h.in, tags.h: Trivial cleanups.
2127 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
2128 marksweep.h just declared functions from gc.c.
2129 * gc.h, libguile.h: Don't #include "marksweep.h".
2130 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2131 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
2132 dependencies updated.
2134 * libguile.h: Don't #include "files.h"; it's been deleted.
2136 * files.c (scm_sys_delete_file): Moved to filesys.c.
2137 File is now empty; deleted.
2139 * filesys.c: scm_sys_delete_file is now here. Remove
2140 #if's; they seem to rely on remnants of an old portability
2141 regimen. If the problems come up again, solve them properly,
2142 using autoconf. Specifically: Don't test M_SYSV, and #define
2143 remove to be unlink if it's #defined; don't use remove just
2144 because HAVE_STDC_HEADERS is #defined.
2145 * filesys.h: Add declarations for scm_sys_delete_file.
2146 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2147 files.o, files.h, files.c, and files.x.
2148 * init.c: Don't #include "files.h", and don't call scm_init_files.
2150 Use SCM_P instead of PROTO; the latter intrudes on the user's
2152 * params.h: Deleted; definition of SCM_P moved to...
2153 * __scm.h: ... here, where it replaces PROTO macro.
2154 * libguile.h, smob.h: Don't #include "params.h".
2155 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
2156 smob.h: Fix prototypes accordingly.
2157 * Makefile.in: Update dependencies.
2158 (inner_h_files): Remove params.h.
2160 * gc.c: #include "gc.h"; every module should include its header,
2161 to let the compiler cross-check the declarations against the
2164 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2165 simpos.h: #include "libguile/__scm.h".
2167 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2169 * init.c: Don't forget to #include smob.h and init.h.
2170 * Makefile.in: Dependencies updated.
2172 * smob.h: Use PROTO instead of #if __STDC__.
2174 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2176 * __scm.h: Doc fixes.
2178 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2179 <angles>; this allows `make depends' to work properly.
2181 * libguile.h: #include smob.h and pairs.h before the others; they
2182 define typedefs used by other headers.
2184 C files should #include only the header files they need, not
2185 libguile.h (which #includes all the header files); the pointless
2186 recompilation was wasting my time.
2187 * Makefile.in (all .o dependency lists): Regenerated.
2188 * libguile.h: Don't try to get a definition for size_t here...
2189 * __scm.h: Do it here.
2190 * _scm.h: Since this is the internal libguile header, put things
2191 here that all (or a majority) of the libguile files will want.
2192 Don't #include <libguile.h> here; that generates dependencies on
2193 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2194 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2195 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

2292 * weaks.c: Get "weaks.h".
2294 * stackchk.h: #include "libguile/debug.h",
2296 * print.h, read.h: #include "options.h", since everyone who uses
2297 either of these files will need that.
2299 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2300 anyone who uses this file will need them to define the smob
2301 printing functions. Also, get markers.h, since people will need
2302 to #define the mark functions.
2304 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2305 * ports.h: ... to here.
2307 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2308 don't rely on archaic C default type rules.
2310 * fports.h: #include "libguile/ports.h", since you need that in
2311 order to parse this.
2313 * genio.h: #include "libguile/print.h", because you need that to
2314 parse this; don't bother #including "ports.h", since print.h gets
2317 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2319 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2320 this; it's now a reference to an element of *scm_root.
2322 * debug.h: Don't #include "options.h"; the compiler won't be able
2323 to find that once the headers are installed; instead, #include
2324 "libguile/options.h".
2325 * gc.h: Same, with marksweep.h.
2326 * mbstrings.h: Same, with symbols.h.
2327 * scmhob.h: Same, with _scm.h.
2328 * smob.h: Same, with params.h.
2330 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2331 C files; there's no need for this, and it forces recompilations
2334 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2336 * error.c (scm_error): declare scm_error_callback.
2338 * error.h: prototype for scm_error_callback.
2340 * __scm.h: define lgh_error.
2341 (SCM_SYSERROR): redefine using lgh_error.
2343 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2345 * error.c (scm_error): new procedure.
2347 * error.h: prototype for scm_error.
2349 * Makefile.in (install): install scmconfig.h from the current
2350 directory, not $(srcdir).
2352 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2354 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2355 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2356 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

2362 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2363 vports.h, weaks.h: #include "libguile/__scm.h", not
2364 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2365 dependencies are within libguile properly.
2367 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2369 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2370 when scmconfig.h doesn't exist.
2372 * load.c (scm_sys_try_load): Correct spelling.
2374 * feature.c (scm_loc_features): Make this static.
2376 * Makefile.in (libpath.h): Omit trailing slash from path. We
2377 shouldn't require it of users, so why put it here?
2379 Move code to initialize and search %load-path from ice-9 to C
2380 code, so we can use the load-path to find the ice-9 boot code;
2381 this makes it easier to run Guile without installing it. See
2382 corresponding changes in guile/Makefile.in.
2383 * feature.c: Move stuff concerned with the load path to load.c.
2384 (scm_compiled_library_path): Deleted.
2385 Don't #include libpath.h here.
2386 * feature.h: Don't mention scm_compiled_library_path.
2387 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2388 <sys/stat.h>, and <unistd.h> (if present).
2389 (R_OK): #define if the system hasn't deigned to.
2390 (scm_loc_load_path): New variable.
2391 (scm_init_load_path, scm_sys_search_load_path,
2392 scm_sys_try_load_path): New functions.
2393 (scm_init_load): Initialize scm_loc_load_path to point to the
2394 value cell of the Scheme %load-path variable.
2395 * load.h: Add declarations for scm_sys_search_load_path,
2396 scm_sys_try_load_path.
2397 * init.c: Call scm_init_load_path.
2398 * Makefile.in (feature.o, load.o): Dependencies updated.
2400 * load.c, load.h: Rewrite using PROTO macro.
2402 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2404 * gc.c (scm_cellp): New function: C predicate to determine if an
2405 SCM value can be regarded as a pointer to a cell on the heap.
2407 * gc.h: Added declaration of scm_cellp.
2409 * gdb_interface.h: New file: The GDB interface header from the GDB
2412 * gdbint.c: New file: GDB interface.
2414 * gdbint.h: New file: GDB interface.
2416 * libguile.h: Added #include <libguile/gdbint.h>.
2418 * init.c (scm_boot_guile): Added scm_init_gdbint.
2420 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2421 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2422 found if object files and source are kept separate).
2424 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2426 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2428 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2430 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2431 TK_SRC_DIR; they're not relevant any more.
2433 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2434 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2436 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2438 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2439 search path, so we can find the <libguile/MUMBLE.h> headers.
2441 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2443 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2444 implicit in the .c.o rule.
2445 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2448 Put the library path in a header file, instead of passing it on
2449 the command line in every compilation.
2450 * Makefile.in (libpath.h): New target.
2451 (feature.o): Depend on libpath.h.
2452 (clean): Delete libpath.h.
2453 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2454 * feature.c: ... #include "libpath.h" here.
2455 * .cvsignore: Ignore libpath.h.
2457 Don't install the unwashed masses of Guile header files in the
2458 main #include path; put most of them in a subdirectory called
2459 'libguile'. This avoids naming conflicts between Guile header
2460 files and system header files (of which there were a few).
2461 * Makefile.in (pkgincludedir): Deleted.
2462 (innerincludedir): New variable; this and $(includedir) are enough.
2463 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
2464 (installed_h_files): Divide this up. Now this variable lists
2465 those header files which should go into $(includedir) (i.e. appear
2466 directly in the #include path), and ...
2467 (inner_h_files): ... this new variable says which files appear in
2468 a subdirectory, and are referred to as <libguile/mumble.h>.
2469 (h_files): List them both.
2470 (install): Create innerincludedir, not pkgincludedir. Put
2471 the installed_h_files and inner_h_files in their proper places.
2472 (uninstall): Corresponding changes.
2473 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2474 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2475 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
2476 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
2477 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
2478 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2479 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2480 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2481 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2482 vports.h, weaks.h: Find __scm.h in its new location.
2483 * __scm.h: Find scmconfig.h and tags.h in their new locations
2484 (they're both "inner" files).
2486 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
2488 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
2490 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2492 * posix.c: Doc fixes.
2494 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
2496 * socket.c: Don't include a prototype for inet_aton; just use a
2497 K&R style declaration, to avoid warnings but minimize the chance
2498 of conflicts with the system.
2500 On NextStep, <utime.h> doesn't define struct utime, unless we
2501 #define _POSIX_SOURCE before #including it.
2502 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
2503 * acconfig.h: New comment text for above CPP symbol.
2504 * configure.in: Call it.
2505 * posix.c: #define _POSIX_SOURCE if it seems necessary.
2507 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
2509 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
2510 testing for __EMX__.
2512 * posix.c: #include <libc.h>, if it exists.
2514 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
2515 don't even know if the latter exists.
2517 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
2518 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
2519 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
2521 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
2523 (scm_init_posix): Use them when initializing the Scheme constants
2526 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2528 * Makefile.in (libdir, includedir, bindir): Use the
2529 autoconf-supplied values, instead of deriving them ourselves.
2530 (pkgincludedir, datadir, pkgdatadir): New variables.
2531 (install, uninstall): Put the header files in a special
2532 subdirectory, not in the main search path.
2534 * Makefile.in (ALL_CFLAGS): Provide the proper value for
2535 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
2537 * Makefile.in (IMPLPATH): Deleted; never used.
2539 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
2540 on the Tcl/Tk source any more.
2541 (INCLUDE_CFLAGS): Remove references to the above.
2543 * Makefile.in (version.o): Corrected dependencies.
2545 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
2547 * libguile.h: #include "version.h"
2549 * init.c (scm_boot_guile): Call scm_init_version.
2550 * gscm.c (gscm_run_scm): Call scm_init_version.
2552 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
2553 GUILE_VERSION): AC_DEFINE these.
2554 (acconfig.h): #undef the above symbols.
2556 * Makefile.in (libobjs): Add version.o.
2557 (installed_h_files): Add version.h.
2558 (c_files): Add version.c.
2559 (gen_c_files): Add version.x.
2560 (version.o): New rule.
2561 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
2562 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
2563 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
2564 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
2565 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
2566 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
2567 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
2568 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
2569 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
2570 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
2571 weaks.o): Add version.h to dependency lists.
2572 (markers.o): Remove duplicate rule.
2574 * version.h: New file.
2576 * version.c: New file.
2578 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2580 * symbols.c (scm_strhash): scm_downcase is now a function, not an
2581 array; use it appropriately. Since GCC is quite happy to
2582 subscript functions, it never warned us about this; we should use
2583 -Wpointer-arith in the future. I guess we never tested
2586 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2588 * socket.c: Doc and copyright fixes.
2590 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2592 * debug.c: Fixed and improved gdb support.
2594 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2596 * socket.c: Added declaration of inet_aton to avoid compiler
2597 warning. (Hope this solution is correct.)
2599 * stime.c: Added declaration of ftime. (This is missing in
2602 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
2604 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2606 * Makefile.in (c_files): add strerror.c.
2608 * strerror.c: new file from Emacs' sysdep.c.
2609 maybe configure should also check for sys_errlist.
2611 * configure.in (AC_REPLACE_FUNCS): add strerror.
2613 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2615 * debug.c (scm_init_debug): Added initialization for
2616 scm_evaluator_traps.
2618 * debug.h, debug.c: Various name changes.
2619 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
2620 "debug-options-interface". See commentary in options.c.
2622 * options.h, options.c: Options now have documentation strings.
2623 Also added a long explanatory commentary.
2625 * eval.c, print.h, print.c, read.h, read.c: Modifications to
2628 * gscm.c, init.c, root.c, throw.c: Bug fixes:
2629 last_debug_info_frame is now updated in all cases.
2631 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
2634 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2636 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
2637 Added option STACK_CHECKING.
2639 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
2641 * Makefile.in: Added {debug,options,srcprop}.{h,c}
2643 * __scm.h: Removed symbols for debugging support.
2645 * acconfig.h: Added symbols for debugging support.
2647 * configure.in: Added user option for debugging support.
2648 --enable-debug will include the debugging code into libguile.a.
2650 * continuations.c (scm_make_cont): Enlarged the #if 0 around
2651 scm_relocate_chunk_to_heap.
2653 * debug.c: New file: low-level debugging support. It also
2654 includes support for debugging with gdb. (The extensions to gdb
2655 are written by Per Bothner at Cygnus.)
2657 * debug.h: New file: low-level debugging support.
2659 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
2660 argument pairs. Extensive modifications to the debugging
2661 evaluator. Added "SECTION:" commentaries to clarify what happens
2662 when, during double compilation. Renamed EVALIMP --> EVALIM.
2663 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
2664 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
2665 the beginning of the file. New procedure: scm_unmemocopy.
2666 Added some global state variables needed by the debugging
2667 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
2668 check_entry, check_apply, check_exit, debug_options and
2669 evaluator_traps. New acro: undefine.
2671 * eval.h: Renamed EVAL --> XEVAL.
2673 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
2674 --> scm_make_weak_key_hash_table.
2676 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
2677 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
2679 * libguile.h: Conditionally include debug.h
2681 * objprop.c (scm_object_properties, scm_set_object_properties_x):
2682 scm_object_properties shouldn't return handle. `handle' now gets
2683 initialized in scm_set_object_properties_x. scm_object_properties
2684 doesn't any longer create an entry in scm_object_whash.
2686 * options.c: New file: handling of run time options.
2688 * options.h: New file: handling of run time options.
2690 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
2692 * print.c: New procedure: scm_print_options
2694 * print.h: Defines for print options.
2696 * read.c: New procedure: scm_read_options
2698 * read.h: Defines for reader options.
2700 * root.h: Added scm_source_whash among scm_sys_protects.
2702 * srcprop.c: New file: source properties.
2704 * srcprop.h: New file: source properties.
2706 * throw.c (jbsmob): Jump buffers are now correctly allocated.
2707 (Bug found by A. Green.)
2709 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2711 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2713 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
2715 * libguile.h: #include "objprop.h"; I guess this was forgotten.
2717 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
2718 and should be called by the final client.
2720 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
2722 * gc.h: Use the PROTO macro when declaring functions.
2723 * gc.c: Use the PROTO macro when declaring static functions.
2724 Remove the CPP hair around function definitions.
2726 * gc.c (scm_init_storage): Initialize scm_asyncs.
2728 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
2729 preprocessor symbol; "__scm.h" is where it might get #defined.
2730 * __scm.h: Similar: #include <scmconfig.h> before testing
2733 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
2735 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
2737 * init.c (scm_boot_guile): Add init_func argument; call
2738 (*init_func) instead of calling scm_appinit; it's ucky to
2739 hard-code names for the user's procedures.
2740 * init.h (scm_boot_guile): Adjust declaration.
2742 * __scm.h (PROTO): New macro, for declaring functions with
2745 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
2746 eliminate all the __STDC__ conditionals.
2747 (scm_boot_guile): Add declaration.
2748 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
2749 Remove __STDC__ conditionals around function definitions; the
2750 declarations in init.h will provide the same information, more
2753 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
2754 complain about it in the error message; the error message is
2755 adequate without that note, and there's nothing the user can do
2758 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
2760 * Makefile.in (ancillary): Drop def.sed.
2762 * posix.c (scm_init_posix): Use numeric values, rather than
2763 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
2764 F_OK. The symbols aren't available on some systems, and I'm
2765 pretty sure their values are fixed by common widespread practice.
2766 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
2768 More functions unavailable on some systems.
2769 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
2770 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
2772 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2773 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
2774 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
2775 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
2776 stub that signals an error as the #else.
2778 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
2780 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
2782 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
2784 * unif.c: include ramap.h.
2786 * read.c (endif): case_insensative_p renamed case_insensitive_p.
2788 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
2790 * ports.c: include sys/ioctl.h.
2792 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
2794 * configure.in: check for sys/ioctl.h.
2796 * ports.c: include <malloc.h> not "malloc.h".
2798 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2800 * fports.c: remove ttyname and tmpnam declarations.
2802 * posix.c: fewer ttyname declarations.
2804 * fports.c: include <string.h> not "string.h".
2806 * init.c, ioext.c: include string.h and unistd.h.
2808 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2810 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
2811 genio.c, simpos.c, vports.c: include string.h.
2813 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
2815 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
2817 (scm_addr_buffer_size): change type from scm_sizet to int.
2818 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
2819 from scm_sizet to int.
2821 * error.c: include unistd.h.
2823 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
2826 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
2828 * __scm.hd, def.sed: deleted.
2830 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
2832 Changes for NeXT, suggested by Robert Brown.
2833 * configure.in: Call AC_TYPE_MODE_T.
2834 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
2835 NeXT. Put header file list in alphabetical order.
2836 * configure, scmconfig.h.in: Regenerated.
2837 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
2839 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
2842 * acconfig.h: New file, providing documentation for the CPP
2843 symbols defined in configure.in
2844 * acconfig-1.5.h: Removed; superceded by the above.
2846 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
2848 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
2850 * fports.c (scm_open_file): don't return #f, throw error.
2852 * ioext.c (fileno): renamed from %fileno.
2853 (soft-fileno): deleted.
2855 * ports.c (scm_port_revealed): don't need to check for -1 from
2857 (scm_set_port_revealed_x): return unspecified, not #f.
2859 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
2861 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
2863 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
2865 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
2867 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2869 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
2870 This is necessary on Ultrix, and doesn't hurt portability.
2872 * Makefile.in (dist-dir): New target, implementing a new dist system.
2873 (installed_h_files): Put in alphabetical order.
2874 Remove duplicate entries for markers.h and unif.h.
2875 (c_files): Remove duplicate entries for markers.c.
2876 (ancillary): Renamed from anillery; all uses changed. Remove
2877 PLUGIN; it's a directory, and needs special treatment in dist-dir.
2878 Remove all the ../doc/* files; doc/Makefile.in handles that.
2880 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
2882 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
2883 every if must have an else, or else the whole command has a
2884 non-zero exit code whenever the if's condition is false.
2886 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
2888 * posix.c: include string.h.
2890 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2892 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
2895 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
2896 Remove leading % from scheme names.

3143 initialization to fix a race condition.
3145 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
