1 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3 * filesys.c (scm_stat): stat now takes fport arguments too as
4 documented in the manual.
6 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
8 * debug.c (scm_single_step): Bugfix: Call continuation with
9 scm_call_continuation instead of throwing to it.
11 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
13 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
14 argument wasn't declared to be optional.
16 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
18 * stime.c (scm_init_stime): Add feature "current-time".
20 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
22 * throw.h: prototype for scm_exit_status.
23 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
24 args to derive an exit status. Allows (quit) to work from a
26 (scm_exit_status): new function.
29 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
31 * eval.c (scm_deval): Removed some old code.
32 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
34 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
37 * symbols.c (msymbolize): Bugfix: Must initialize property list to
40 * procs.c: Introduce the existent C function scm_thunk_p at the
43 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
45 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
46 used from C to easily lookup the value of a symbol in the current
49 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
51 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
52 scm_init_unif in this file. This will also fix a previous problem
55 * configure.in: Added AM_MAINTAINER_MODE
57 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
59 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
62 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
64 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
65 source files that are not always included in libguile but should
66 have their dependencies calculated by automake. This variable is
67 recognized by automake, no further magic is needed.
68 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
69 to deal exclusively with *.lo files, as it seems. The *.o files
70 are built automatically when the corresponding *.lo file gets
73 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
75 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
78 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
80 * unif.c (scm_array_set_x): minor change to argument error checking.
82 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
84 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
85 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
86 They should only be included in the library at configure.in's
88 (libguile_la_LDADD): Include the appropriate .lo files here.
89 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
90 so we know when to build them (and their .lo bretheren).
91 * configure.in (LIBLOBJS): New substituted variable. We let
92 configure decide which .o files to include in LIBOBJS, and then
93 put the corresponding list of .lo files in LIBLOBJS. The latter
94 is what we pass to libtool.
95 * Makefile.in, configure: regenerated.
97 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
99 * symbols.c (scm_sysintern0): New function. Contains the core of
100 old scm_sysintern but doesn't take a second value argument.
101 (scm_sysintern): Now uses scm_sysintern0.
102 (scm_sysintern_no_module_lookup): Renamed to
103 scm_sysintern0_no_module_lookup and doesn't take a second value
106 * symbols.h (scm_sysintern0: Added declaration.
108 * options.c (scm_init_opts): Use scm_sysintern0 instead of
109 scm_sysintern when interning option keys. Otherwise we risk
110 destroying the values of already interned variables.
112 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
113 scheme-level boolean (use SCM_NFALSEP).
115 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
117 (scm_backtrace): New function. (C version of old function from
118 boot-9.scm) Motivation: Make it possible to display backtraces
119 without depending on boot-9.scm. (I'm uncertain if this
120 motivation is good enough...)
122 * root.h (scm_root_state): Add member the_last_stack_var.
123 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
125 * root.c (mark_root): Mark scm_the_last_stack_var.
127 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
130 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
132 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
133 1. mark_lazy_catch didn't mark the smob.
134 2. Both functions above have standard variants:
135 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
136 free_lazy_catch --> scm_free0.
138 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
140 * throw.c (scm_internal_lazy_catch): New function.
141 (scm_lazy_catch): Rewritten to use it.
142 (scm_ithrow): Handle the new lazy catch representation.
143 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
144 that doesn't have a jmpbuf is a lazy catch clause.
145 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
146 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
147 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
149 (scm_init_throw): Register the new lazy-catch smob type.
150 * throw.h (scm_internal_lazy_catch): decl for new function.
152 * throw.c (scm_internal_catch): Doc fixes.
154 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
155 configure.in. Including this might cause problems if applications
156 that link against libguile include their own copies of alloca, but
157 if they're using autoconf, they should be adding libguile to LIBS
158 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
159 the copy in libguile, and things will be okay. (I think.)
161 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
163 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
165 strop.h: move prototypes too.
167 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
169 * posix.c (scm_init_posix): don't intern EINTR since it's now done
172 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
173 etc. I deleted them from filesys.c long ago, but didn't
174 notice they were here too (although ineffective since
175 sys/stat.h wasn't included).
177 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
179 * eval.c: Don't define alloca in GCC case. gcc will automatically
180 use __builtin_alloca if appropriate.
182 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
184 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
185 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
186 that values of automatic variables are preserved. See comments
187 for safe_setjmp for details.
189 Change from Thomas Morgan:
190 * variable.c: Include eq.h.
191 (var_equal): New function.
192 (variable_smob): Use var_equal as the discriminator for variables.
194 * throw.c (s_throw): Remove extraneous declaration.
196 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
197 * eval.c: Add necessary CPP cruft to support that.
198 * configure, Makefile.in, scmconfig.h.in: regenerated.
200 Change from Thomas Morgan:
201 * procprop.c (scm_procedure_properties): Convert the Scheme
202 boolean returned by scm_procedure_p into a C boolean before using
203 it as a condition for SCM_ASSERT.
204 (scm_procedure_property): Likewise.
206 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
207 indications of Unixness.
210 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
212 * * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
214 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
216 * read.c (scm_lreadr): use scm_misc_error to improve one of the
217 "unknown # object" error messages.
219 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
220 (scm_i_index) and declare it static. Add a 'direction' argument
221 to indicate what way the search should go.
222 (scm_i_index): throw out-of-range error instead of wrong-type-arg
224 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
225 strop.h: remove scm_i_index, scm_i_rindex prototypes.
227 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
229 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
231 * * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
232 to avoid clash with various scsh forks.
234 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
236 The following two changes (ramap.c, throw.c) are motivated by the
237 apparent unportability of forward declarations of static arrays of
238 the form `static foo bar[];'.
240 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
241 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
243 * throw.c (scm_throw): Moved above scm_ithrow.
245 * options.h: Removed the extern declarations of scm_yes_sym and
246 scm_no_sym since these are static.
248 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
250 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
252 * Makefile.am: remove AWK=@AWK@.
253 Add a rule for generating errnos.list.
254 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
256 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
257 don't extract errnos, just set a variable (avoids the
258 need to recompile error.c just because configure is run.)
260 * unif.h: update prototypes.
261 * unif.c (scm_uniform_array_read,write): change the offset and
262 length arguments to start and end, for consistency.
264 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
266 * ioext.h: update prototypes.
267 * * ioext.c (scm_read_delimited_x): replaces scm_read_line and
268 scm_read_line_x, it's a more general procedure using an
269 interface from scsh. read-line and read-line! are now defined
271 * Note that the new read-line trims the terminator
272 by default, previously it was appended to the returned string. An
273 optional argument specifies how to process the terminator (scsh
274 compatible). For the old behaviour: (read-line port 'concat).
275 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
276 returns a pair, but is converted to multiple values if the scsh
279 socket.h: update prototypes.
280 * socket.c (scm_recvfrom): for consistency with other procedures,
281 take start and end as separate optional arguments.
282 * (scm_recv, scm_recvfrom): don't allow the second argument
283 to be a size, only a buffer. Change the scheme names to
284 recv! and recvfrom!. Don't return the buffer.
286 * ioext.h, posix.h: move prototypes too.
287 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
288 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
289 "read.h" and "unif.h".
290 * ioext.c: include "chars.h"
292 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
294 * dynl.c: The dynamic linking and module registration functions
295 are now defined even when dynamic linking is not available for the
296 host system. Some of their functionality can be done without
297 dynamic linking; when it's really needed, they throw errors.
299 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
301 * configure.in: Only define DYNAMIC_LINKING when one of the system
302 dependent functions is detected.
303 * dynl.c (scm_dynamic_func): New function to get the address of a
304 function in a dynamic object.
305 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
306 produced by scm_dynamic_func as the thing to call.
308 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
310 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
311 (scm_register_module_xxx, scm_registered_modules,
312 scm_clear_registered_modules): New functions.
314 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
316 * symbols.c (scm_sysintern): Renamed to
317 scm_sysintern_no_module_lookup.
318 (scm_sysintern): New function to take the place of the old
319 scm_sysintern. It uses the current toplevel lookup closure to give
320 the symbol its value. This is a temporary hack to put packages
321 like gtcltk into their own module.
322 (scm_can_use_top_level_lookup_closure_var): New variable to tell
323 us whether `scm_top_level_lookup_closure_var' has been initialized
325 * eval.c (scm_init_eval): Set it.
327 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
329 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
330 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
332 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
334 * (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
335 scm_sys_dup): deleted: FD capability will be added to other
337 * Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
338 scm_fd_free, fd_smob, scm_intern_fd.
339 * (scm_open): renamed from scm_sys_open. Return a port instead of
340 an FD object. Make the mode argument optional.
341 * (scm_sys_create): deleted, it's just a special case of open.
342 (scm_init_filesys): move interning of constants O_CREAT etc.,
343 here (were previously using SCM_CONST_LONG macro).
344 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
346 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
347 include "fports.h" and <stdio.h>
348 (scm_stat, scm_select): don't support FD objects.
350 * error.h: adjust scm_syserror_msg prototype.
351 * error.c (scm_syserror_msg): take an extra argument for errno.
352 Using the global value didn't always work, since it could be
353 reset by procedure calls in the message or args arguments.
355 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
356 I don't understand why the check was there (and what about the
359 * strop.c (scm_string_copy): allow shared substrings to be copied.
361 * unif.h: corresponding change to prototypes.
362 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
363 recognize two new optional arguments: offset and length. Allow
364 the port argument to be an integer (file descriptor, for scsh).
365 Include <unistd.h> for "read" prototype.
367 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
369 * socket.c: don't include filesys.h.
371 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
373 * Makefile.am: add AWK=@AWK@ (?)
375 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
377 Add a rule to generate errnos.c from errnos.
378 * error.c (scm_init_error): include errnos.c.
379 * errnos_cnvt.awk: new file, converts the list of errno codes to
381 * errnos_get.c: new file.
382 * errnos.default: new file, contains errnos to try if they can't
383 be extracted from errno.h.
384 * configure.in: if using GCC, try and extract errno codes from
388 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
390 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
391 * Makefile.am: Made libguile into a libtool library.
392 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
393 Set libtool_libs to indicate that libguile is a libtool library.
394 See guile/ChangeLog for details.
395 * .cvsignore: ignore "*.lo", the libtool library objects.
397 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
399 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
400 use htons in getservbyport argument.
402 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
404 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
405 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
408 * objprop.c (scm_object_property): No need to take the CDR of the
409 value returned by scm_object_properties, since Aug 20 change.
411 * configure.in: When checking for struct linger, #include
412 <sys/types.h> as well as <sys/socket.h>. I've never known
413 <sys/types.h> to cause any portability problems, and Solaris's
414 <sys/socket.h> needs it.
415 * configure: Rebuilt.
417 I think the Sun compiler has chosen a perverse way to interpret
418 ANSI declarations combined with K&R definitions. We'll
419 appease it a little bit. But when it invades France, we fight.
420 * print.c (scm_iprlist): Change 'tlr' argument to an int.
421 * print.h (scm_iprlist): Here too.
422 * numbers.c (scm_divbigdig): Change definition to match
423 declaration in numbers.h.
424 * unif.c (scm_makflo): Change definition to match declaration in
427 * init.c (scm_boot_guile): Don't return the value of
428 scm_boot_guile_1. This function doesn't return a value;
429 scm_boot_guile_1 doesn't return a value (or return at all).
431 * eval.c (unmemocopy): Add a semicolon to appease the Sun
434 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
435 compile. I have a feeling this function is a bad idea anyway ---
436 one should always test for features, not systems.
438 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
439 semicolons. Only pure luck kept this from being noticed earlier.
441 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
443 * socket.c (scm_recvfrom): Added missing semicolon.
445 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
447 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
448 the buffer and start and end positions for scsh networking
451 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
453 * configure.in: Revert previous change to this file; the problem
454 is due to transient automake weirdness.
455 * configure: Rebuilt.
457 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
458 PLUGIN/guile.libs. configure generates the latter from the former.
459 * Makefile.in: Rebuilt.
461 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
462 need this if we install scripts, like guile-snarf.
463 * configure: Rebuilt.
465 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
467 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
469 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
471 * socket.c (scm_addr_vector): fix faulty scm_listify.
473 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
475 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
476 style block comment is no longer considered an error.
478 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
480 * PLUGIN/guile.libs.in: New file.
481 * PLUGIN/guile.libs: Removed from repository.
482 * configure.in: Create PLUGIN/guile.libs from
483 PLUGIN/guile.libs.in. This is for including additonal libraries
484 needed for dynamic linking.
485 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
486 instead of PLUGIN/guile.libs.
488 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
490 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
492 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
493 occurrences of the given element from the list, not just the
494 first. This is how the Emacs Lisp functions behave, how the
495 analogous Common Lisp functions behave, and (I believe) how the
496 older Maclisp functions worked. I realize that this change may
497 break code, but it seemed better to break it before the Guile
500 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
501 Their prototypes were already present in gc.h, but they weren't
503 (scm_init_storage): Initialize scm_protects.
504 * root.c (scm_protects): New element of scm_sys_protects.
506 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
508 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
510 * libguile.h: Added #include "libguile/net_db.h".
512 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
513 30 change. That file is only meant for communication between the
514 configuration process and load.c. If code linked against libguile
515 wants to get at the paths mentioned in libpath.h, it can call
516 functions declared in load.h.
518 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
520 * libguile.h: Removed #include "libguile/fdsocket.h"
522 * net_db.c: Added #include <sys/socket.h>.
524 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
526 * filesys.c (scm_input_waiting_p): use select in preference to
527 FIONREAD, since the latter doesn't detect EOF.
528 Throw error if neither select nor FIONREAD available.
530 * socket.c (scm_connect): take a port, not a fd object.
531 (scm_fill_sockaddr): throw an error if fam is not recognised.
532 (scm_bind): use scm_fill_sockaddr.
533 (scm_listen): take a port, not a fd object.
534 (scm_accept): take and return a port. return #f in the car if
536 (scm_sock_fd_to_port): new procedure.
537 (scm_socket): use scm_sock_fd_to_port.
538 (scm_addr_vector): throw error if unrecognised address type.
539 take an extra argument with the calling procedure name.
540 (scm_getsockname): take a port. return #f if address can't be got.
541 (scm_getpeername): take a port. return #f if address can't be got.
542 (scm_recvfrom): take a port. return #f for address component if can't
544 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
545 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
547 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
549 * throw.c (scm_internal_catch): Make body funcs and handler funcs
550 use separate data pointers, to allow them to be designed
551 independently and reused.
552 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
553 Renamed from catch_body, catch_handler, and uncaught_throw; made
555 (struct scm_catch_body_data): Renamed from catch_body_data; moved
557 (scm_catch): Use the above.
558 (scm_throw): Don't bother printing a message for an uncaught
559 throw; we establish a default handler in init.
560 * throw.h (scm_internal_catch): Prototype updated.
561 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
563 (struct scm_body_thunk_data): New structure, used as data
564 argument to scm_body_thunk.
565 * init.c (struct main_func_closure): New structure, packaging up
566 the data to pass to the user's main function.
567 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
568 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
569 scm_internal_catch to establish a catch-all handler, using
570 scm_handle_by_message. This replaces the special-case code in
572 (invoke_main_func): Body function for scm_internal_catch; invoke
573 the user's main function, using the main_func_closure pointer to
574 decide what to pass it.
575 * root.c (struct cwdr_body_data): Remove handler_proc member.
576 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
577 (cwdr_handler): Removed.
579 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
581 * socket.h (SCM_P): update bind prototype.
582 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
584 (scm_socket): return a port, not a file descriptor object.
585 include "fports.h" and <unistd.h>
586 (scm_bind): take a port, not a file descriptor object.
587 take an extra argument for address args.
589 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
590 INADDR_NONE, INADDR_LOOPBACK.
592 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
594 * init.c: include net_db.h and not fdsocket.h.
595 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
597 * Makefile.am: corresponding changes.
598 * socket.h: renamed from fdsocket.h, fix names.
599 * net_db.h: renamed from socket.h, fix names.
600 * socket.c: renamed from fdsocket.c.
601 remove _sys from procedure names.
602 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
603 add "socket" to features list.
604 * net_db.c: renamed from socket.c.
605 remove _sys from procedure names.
606 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
607 add "net-db" to features list.
608 include "net_db.h". don't include <sys/socket.h> or
611 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
613 * tags.h (scm_tags): Removed comma at end of last enumerator.
615 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
617 Don't use GCC extensions to allocate space for debugging frames.
618 (Here he goes again! Why do we put up with this?!)
619 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
620 an scm_debug_info structure, not an in-line array of them. Add
621 'info' member, to say how many vect elements we've used, for eval
623 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
624 a new variable debug_info_end to mark the end of vect, instead of
625 the address of the 'info' pointer itself.
626 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
627 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
628 (SCM_APPLY): Explicitly allocate space for debug.vect.
629 * debug.c (scm_m_start_stack): Same, for vframe.vect.
630 * stacks.c: Adjusted for new debug frame structure.
631 (RELOC_INFO, RELOC_FRAME): New macros.
632 (stack_depth, read_frames): Use them, and new scm_debug_frame
633 element 'info', instead of magically knowing that eval frames have
634 an info pointer sitting after vect.
635 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
637 (scm_init_stacks): Formatting tweaks.
639 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
641 Give GCC more control flow information, so it can be sure that
642 variables aren't used uninitialized.
643 * error.h (scm_error, scm_syserror, scm_syserror_msg,
644 scm_sysmissing, scm_num_overflow, scm_out_of_range,
645 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
646 scm_misc_error): Tell GCC that these functions never return.
647 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
648 out the field type, call abort if SCM_ASSERT returns, to placate
650 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
651 scm_wta ever returns. We can't handle this case anyway, and this
652 gives the optimizer more information.
653 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
654 scm_wta ever returns.
656 In some cases, the code is fine, but GCC isn't smart enough to
657 figure that out; this usually happens when one variable is only
658 initialized and used when a particular condition holds true, and
659 we know that condition will never change within a given invocation
660 of the function. In this case, we simply initialize the variables
661 to placate the compiler, hopefully to a value which will cause a
662 crash if it is ever actually used.
663 * print.c (scm_iprin1): Initialize mw_pos.
664 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
665 * throw.c (scm_ithrow): Initialize dynpair.
666 * unif.c (scm_uniform_vector_ref): Initialize cra.
667 * struct.c (init_struct): Initialize prot.
668 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
670 * strports.c (scm_eval_0str): Don't return uninitialized garbage
671 if EXPR contains no expressions.
673 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
675 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
676 cause an infinite loop (???). So much for the algebraic
677 equivalency of variable-sized arrays and alloca...
679 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
681 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
682 a SCM boolean, not a C boolean.
684 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
686 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
687 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
688 rules for raising scm_mtrigger. Previously, unfortunate but not
689 unlikely circumstances could result in almost constant invokation
690 of the gc. Now, this situations should be less likely, but they
691 are not prevented completely.
693 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
695 * numbers.c (scm_fuck): Procedure removed; looks like old test
697 * numbers.h: Prototype removed.
699 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
701 * debug.h (scm_debug_frame): Change `vect' member from an in-line
702 array to a pointer, to match my Nov 21 change in eval.c.
704 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
706 * libguile.h: Added #include "libguile/backtrace.h", #include
709 * strings.c (scm_string scm_make_string scm_string_ref
710 scm_string_set_x scm_string_equal_p scm_string_append):
711 Bugfix according to scm patch from Aubrey Jaffer:
712 Corrected long-standing
713 (not (eqv? (integer->char 128)
714 (string-ref (make-string 1 (integer->char 128)) 0)))
715 bug found by John Kozak <jk@noontide.demon.co.uk>.
717 * strports.c, strports.h: Make scm_eval_0str return the value of
718 the last expression evaluated (previously, it returned void).
720 * strports.c, strports.h: New function: scm_read_0str. Does what
723 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
725 * simpos.c (scm_getenv): return #f if string can't be found in the
726 environment instead of throwing an exception, for compatibility
727 with numerous other systems.
729 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
731 * Makefile.am (.c.x): Use guile-snarf.
732 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
734 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
736 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
738 * backtrace.c (scm_display_error_message): Made non-static, and
739 renamed from display_error_message.
740 * backtrace.h (scm_display_error_message): Added extern decl.
741 * throw.c (uncaught_throw): Use it to display the error message.
743 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
745 * inet_aton.c: Use #if 0, not #ifdef 0.
747 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
749 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
750 to convert the returned value.
751 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
754 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
756 Add new interface to catch/throw, usable from C as well as
758 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
759 (scm_internal_catch): New function, replaces...
760 (scm_catch_apply): Deleted.
761 * throw.c (scm_catch_apply): Deleted; replaced with a more general
762 mechanism which is a bit more code, but can be used nicely from C
763 and implement the Scheme semantics as well.
764 (scm_internal_catch): This is the replacement; it's named after
765 the analogous function in Emacs.
766 (scm_catch): Reimplemented in terms of the above.
767 (struct catch_body_data, catch_body, catch_handler): New
768 functions, used by scm_catch.
769 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
770 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
771 support for new cwdr.
773 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
776 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
778 * acconfig.h: Added DYNAMIC_LINKING symbol.
779 * configure.in: Add option and checks for dynamic linking.
780 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
781 dynl.h: New files for dynamic linking support.
782 * Makefile.am (libguile_a_SOURCES):
784 (modinclude_HEADERS): Added "dynl.h".
785 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
787 * init.c (scm_boot_guile_1): Call
788 scm_init_dynamic_linking to initialize dynamic linking support.
790 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
792 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
793 (as we Schemers say). It needs to be global, so that I can tweak
794 it for the proper operation of unexec.
795 (scm_boot_guile_1_live): New variable, see above.
797 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
799 * guile-snarf.sh: Removed.
800 * PLUGIN/guile.libs: Added dependency for -lm.
801 * acinclude.m4: Renamed from aclocal.m4.
802 * PLUGIN/greet: Removed.
803 * Makefile.am, aclocal.m4: New files.
804 * configure.in: Updated for Automake.
806 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
808 * eval.c (scm_definedp): Use top_level_lookup_closure_var
809 and not top_level_lookup_thunk_var.
811 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
813 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
815 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
817 * eval.c (scm_definedp): Incompatibly changed to be a builtin
818 Scheme function, instead of syntax. Single argument is now a
821 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
823 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
824 scm_ra_divide): Properly terminate statements passed as arguments
825 to IVDEP macros. (Thanks to Bernard Urban.)
827 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
828 with non-constant sizes. (Thanks to Bernard Urban.)
830 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
832 It's an "eval closure", not an "eval thunk." A thunk is a
833 function of no arguments.
834 * root.h (struct scm_root_state): Renamed
835 top_level_lookup_closure_var from top_level_lookup_thunk_var.
836 (scm_top_level_lookup_closure_var): Renamed from
837 scm_top_level_lookup_thunk_var.
838 * root.c (mark_root): Uses changed.
839 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
840 * init.c (scm_start_stack): Uses changed.
841 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
842 Change scheme-visible name to *top-level-lookup-closure* from
843 *top-level-lookup-thunk*.
845 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
847 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
848 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
850 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
852 * gc.c (struct scm_heap_seg_data): Doc fixes.
854 * gc.c (scm_gc_sweep): Empty all segments' freelists before
855 sweeping. Then, prepend each segment's free cells to its
856 freelist, rather than wiping out the old value. (Thanks to Marius
859 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
860 scm_check_freelist, scm_debug_newcell): New functions and
861 variables, for debugging freelist problems.
862 * pairs.h (SCM_NEWCELL): New debugging version added.
863 * gc.h (scm_debug_newcell): Added extern declaration, used by
864 debugging version of SCM_NEWCELL.
866 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
868 On some systems <libc.h> conflicts with <unistd.h>, and should not
870 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
871 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
872 * configure.in: Call it.
873 * posix.c, filesys.c: Use its results to decide whether or not to
875 * configure, scmconfig.h.in: Rebuilt with autoconf and
878 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
880 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
881 pointer to the stdio stream before calling scm_setbuf0, so the
882 latter will be able to retrieve it. I'm surprised this didn't
883 segfault earlier. (Thanks to Christopher Lee.)
885 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
887 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
890 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
892 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
893 number of stack narrowing specifier pairs. The first specifier in
894 a pair controls inner border, the second the outer border. A
895 number means cut that number of frames, a procedure object means
896 cut until that object is found in operator position in a frame.
898 * root.c (cwdr): Bugfix.
900 * read.c: Recording of positions disabled by default.
902 * procs.c (scm_closure_p): New function.
904 * posix.c (scm_tmpnam): New function.
906 * load.c: Added #include "throw.h".
907 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
910 * load.c, load.h (scm_read_and_eval_x): New function.
912 * eval.c: Renamed debug option "deval" to "debug".
914 (scm_eval_x): `eval!' is no longer accessible from the scheme
915 level. Motivation: We can't allow operations which introduce
916 glocs into the scheme level. Guile's type system can't handle
917 these as data. Use `eval' or `read-and-eval!' as replacement.
919 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
920 SCM_CONSP since this is a macro!; Set vframe.prev to
921 scm_last_debug_frame instead of 0. In this way we can look
922 "above" the virtual start stack frame if we wish.
923 (scm_debug_hang): New function: Useful for debugging Guile in
924 certain tricky situations. Will probably be removed later...
926 * debug.h: Changed semantics of debug option "backtrace". This
927 option now only indicates whether we want automatic backtrace at
930 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
932 * ports.c: #include "filesys.h"
933 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
935 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
936 Motivation: This is system specific code which is related to file
937 I/O. It also may use select. Added code by Gary Houston to
938 detect presence of character in stdio buffers.
940 * libguile.h: #include "libguile/libpath.h"
942 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
943 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
944 SCM_SITE_DIR; Install libpath.h among the other include files.
946 * load.c, load.h (scm_sys_package_data_dir): New function.
948 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
950 * stacks.h: Bugfix: Don't use tail-array length field as stack
951 length field! This screwed GC.
953 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
955 * _scm.h: Added #ifndef around definition of macros min and max.
957 * __scm.h: Added hooks for threads to plugin to in ints protection
958 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
959 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
960 the main code in these macros duplicated and spread over multiple
961 files. Renamed SCM_THREADS_SWITCHING_CODE ->
962 SCM_THREAD_SWITCHING_CODE.
964 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
967 * guile-snarf.sh: New file.
968 * Makefile.in (inner_h_files): Added snarf.h
969 (ancillary, install, uninstall, distclean): Added actions for
971 (.c.x): Use guile-snarf.
972 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
973 (gen_c_files): Note that these depend on guile-snarf.
974 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
975 now in "snarf.h". Added #include "snarf.h" to get them.
976 * libguile.h: Added #include "snarf.h".
977 (Patches applied and tweaked by Jim Blandy.)
979 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
981 * socket.c: Use K&R style declaration for 'close'; the GNU coding
982 standards suggest against providing prototypes for system
983 functions. Thanks to Greg Troxel.
985 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
987 * strports.c (scm_eval_0str): New function.
988 #include "read.h", to get prototype for scm_read.
989 * Makefile.in (strports.o): Update dependencies.
990 * strports.h: New prototype.
992 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
993 scheme name from "int?" to "integer?". It seems to do the job.
994 * numbers.h: Rename prototype too.
995 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
998 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
999 scm_num_eq_p): Rename these according to R4RS conventions: call
1000 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
1001 to making libguile R4RS compliant without ice-9...
1003 * load.c (scm_sys_search_load_path): Search for files under all
1004 extensions listed in the %load-extensions variable. If FILENAME
1005 is absolute, return it unchanged, without searching the load path.
1006 (scm_loc_load_extensions): New variable, pointing to
1007 %load-extensions' value cell.
1008 (scm_init_load): Initialize it, and the value it points to.
1009 (scm_primitive_load_path): Improve error reporting.
1011 * load.c (scm_loc_load_hook): New variable, pointing to value cell
1012 of new Scheme variable %load-hook.
1013 (scm_primitive_load): Apply %load-hook to filename.
1015 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
1017 * configure.in: add tests for figuring out whether buffered data
1018 is available in a FILE structure, which is needed by char-ready.
1020 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
1023 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
1024 exceptions using misc_error instead of syserror. It seems a bit
1025 odd to throw an exception if a string can't be found in the
1026 environment, but it's consistent with open-file, stat etc.
1027 (simpos.h): remove sys_ from getenv.
1029 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
1030 occurs, throw an error instead of returning errno. Return value
1032 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1034 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1036 * filesys.c (scm_stat2scm): derive file type and permissions from
1037 the stat mode and append them to the returned vector.
1038 There isn't much overhead in doing this and it avoids the need to
1039 work with S_IRUSR et al. in Scheme.
1040 Define symbols scm_sym_regular etc.
1041 (scm_init_filesys): don't intern S_IRUSR etc.
1043 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1044 and s_primitive_load_path.
1046 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1048 * error.h: don't declare error symbols. prototype for scm_misc_error.
1050 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1053 * error.c: use SCM_SYMBOL to set up error keys.
1054 scm_misc_error: new procedure.
1056 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1058 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1059 between `#!' and `!#' is ignored.
1060 (skip_scsh_block_comment): New function.
1062 * feature.c (scm_set_program_arguments): New argument, FIRST.
1063 * feature.h: Update prototype.
1064 * init.c (scm_boot_guile_1): Pass new argument to
1065 scm_set_program_arguments.
1067 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1069 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1070 (scm_boot_guile): Call scm_set_program_arguments here, later than
1071 the old initialization.
1073 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1074 initialization procedure.
1075 - Delete in, out, err arguments; there are other perfectly good
1076 ways to override these when desired.
1077 - Delete result argument; this function shouldn't ever return.
1078 - Rename init_func argument to main_func, for less confusion.
1079 - Delete boot_cmd argument; main_func is more general.
1080 -Add 'closure' argument, to help people pass data to main_func
1081 without resorting to global variables.
1082 - Abort if reentered; don't bother returning an error code.
1083 - Call scm_init_standard_ports to set up the default/current
1084 standard ports; no need to pass them to scm_start_stack.
1085 - Remove code to evaluate the boot_cmd, and start the repl; let
1086 the user do something like that in main_func if they want.
1087 - Remove code to package up a return value; main_func can do any
1089 - Call exit (0), instead of returning.
1090 (scm_start_stack): Don't initialize the I/O ports here; that's
1091 weird. Delete in, out, err arguments. Move guts to
1092 scm_init_standard_ports, scm_stdio_to_port.
1093 (scm_init_standard_ports): New function, to set up current and
1094 default standard ports.
1095 (scm_start_stack, scm_restart_stack): Make these static.
1096 * init.h (scm_boot_guile): Adjust declaration.
1097 (scm_start_stack, scm_restart_stack): Remove externally
1098 visible declarations for these.
1099 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1101 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1102 written out several times in scm_start_stack.
1103 * fports.h: New declaration for the above.
1105 * feature.c (scm_set_program_arguments): New function.
1106 * feature.h: New declaration for the above.
1108 * ports.c: Formatting tweak.
1110 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1112 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1113 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1114 for obtaining the address of a car or cdr field. Motivation:
1115 &SCM_CXR make assumptions about the internal structure of the
1118 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1119 Motivation: see SCM_CXRLOC.
1121 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1122 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1123 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1124 Motivation: Safer use. Some other macros are defined in terms of
1125 these operations. If these are defined using the SCM_SETCXR
1126 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1127 to inefficiency and an <e1> with side-effects could potentially
1128 break. Also, these particular operations are heavily utilized in
1129 the garbage collector. In unoptimized code there will be a
1132 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1133 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
1134 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
1135 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
1136 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
1137 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1138 vports.c: Cleaned up use of pairs: Don't make any special
1139 assumptions about the internal structure of selectors and
1140 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1141 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1142 (Among other things, this change makes it easier to build Guile
1143 with certain compilers which have problems with casted lvalues.)
1145 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1147 * stacks.c: Improve selection of relevant stack frames when making
1148 a stack object. Introduce one level of indirection in the stack
1149 object to make it possible to "narrow" to a certain region of the
1150 stack. This facilitates making use of more clever algorithms (not
1151 implemented) for selecting relevant frames and gives a cleaner
1152 design since selection of frames can be done independently of
1153 extraction of frames from the real stack.
1154 (scm_stack_id): Also take #t as argument which means look at
1157 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1158 Turn n_tail into an integer directly representing current number
1159 of frames in stack. Add field tail.
1161 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1163 * debug.c (scm_make_memoized): Made it available at scheme level.
1164 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1165 SCM_NIMP before applying heavier predicates in argument checking.
1166 (scm_local_eval): Also take memoized object as argument.
1168 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1169 aren't created with zero length, but should such a strange
1170 creature suddenly turn up...
1172 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1174 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1175 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1177 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1179 * variable.c (scm_make_variable): Make the name hint optional, as
1181 (anonymous_variable_sym): Renamed from variable_sym. All uses
1184 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1185 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1186 of scm_primitive_load_path was also changed to
1187 "primitive-load-path", from "%try-load-path". Callers changed.
1188 We'd like to respect the convention that a function named
1189 "try-mumble" should behave just like the function called "mumble",
1190 but return #f instead of signalling some error.
1191 * load.h: Rename prototypes.
1193 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1195 * print.c (make_print_state, grow_print_state), print.h: Modified
1196 the print state representation: Don't use a tail array for
1197 recording of circular references. Resizing of the print state
1198 structure invalidates the print state pointer. To avoid passing
1199 around an indirect print state reference to all printing
1200 functions, we instead let the print state reference a resizable
1203 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1205 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1206 Don't crash when passed an improper list terminated by a
1207 non-immediate value.
1209 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1211 Allocate data for structures on an eight-byte boundary, as
1212 required by the tagging system.
1213 * struct.c (alloc_struct): New function.
1214 (scm_make_struct, scm_make_vtable_vtable): Call it.
1215 * struct.h (scm_struct_n_extra_words): Bump to 3.
1216 (scm_struct_i_ptr): New "field".
1217 * gc.c (scm_gc_sweep): When we need to free the data, use the
1218 information stored by alloc_struct to find the beginning of the
1219 block allocated to the structure, so we can free it.
1221 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1223 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1226 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1227 (scm_debug_info): New member: id.
1229 * stacks.c: Stacks are now represented as structs; Stacks have an
1230 id given to them by `start-stack'.
1231 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1233 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1234 Changed stack representation.
1236 * debug.c (scm_procedure_name): Try procedure property `name' for
1237 compiled closures aswell.
1239 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
1241 * eval.c: scm_i_name moved to gsubr.c
1242 (scm_m_define): Record names of all kinds of procedure
1243 objects. (Earlier, only closures were recorded.)
1245 * procprop.h: Added declaration of scm_i_name.
1247 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1248 (scm_make_gsubr): Record names of compiled closures.
1250 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1252 * debug.c, debug.h: Removed obsolete code.
1254 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1255 stacks.c: Renamed regs --> scm_contregs.
1257 * print.c (scm_free_print_state): Cleanup print state before
1258 returning it to pool. It is better to do it here than in
1259 scm_prin1 since scm_prin1 is called often.
1261 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1262 s_set_source_property_x): Check that first argument is a pair or a
1265 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1266 scm_i_line, scm_i_column and scm_i_breakpoint global.
1268 * init.c: Added #include "backtrace.h" and #include "stacks.h".
1269 (scm_boot_guile_1): Added calls to scm_init_backtrace and
1272 * debug.h: Added debug object smob declaration and macro
1275 * configure.in: Build with backtrace.o and stacks.o if debug
1278 * Makefile.in: Added entries for new files: backtrace.c,
1279 backtrace.h, stacks.c and stacks.h.
1281 * symbols.c (scm_sym2ovcell): Fixed documentation.
1283 * _scm.h (min, max): Added.
1285 * async.c: Moved `min' macro to _scm.h.
1287 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1288 SCM_BACKTRACE_INDENT.
1290 * eval.c: Added new debug options `maxdepth' and `indent'.
1292 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
1294 * print.h: Added selector SCM_PRINT_STATE.
1296 * print.c: New functions: scm_make_print_state,
1297 scm_free_print_state.
1299 * print.h: Added declarations for scm_make_print_state,
1300 scm_free_print_state.
1302 * debug.c (scm_m_start_stack): New acro.
1304 * debug.h: Small cleanup.
1306 * init.c (scm_boot_guile_1): Moved scm_init_debug below
1309 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

1329 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
1330 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
1331 declare functions with prototypes. (Patch thanks to Marius
1334 More prototype-related changes from Marius Vollmer:
1335 * gdb_interface.h: Wrapped header file in #ifdef/#endif
1336 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
1337 * ports.h (ptobfuns): Added prototypes. This means some casting in
1339 * fports.c: Added casts for initializations, since the functions
1340 are defined to take FILE * as their stream argument, not SCM.
1341 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
1342 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
1343 to `char *str_data' to conform to prototype.
1345 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1347 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
1349 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
1351 * stime.c, stime.h: use SCM_P method.
1353 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1355 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
1356 be given at least two arguments. Insist that lst's last element
1357 be a list, but don't make any requirements of its predecessors.
1359 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1361 * eval.c (scm_nconc2last): Revert last change; there seems to be
1362 other stuff going on here.
1364 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1366 * eval.c (scm_nconc2last): Make sure that each element of lst
1367 (which is a list of argument lists, except for the tail) is a
1368 proper list, i.e., finite and terminated by '().
1370 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1372 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
1375 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
1376 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
1379 * vectors.c (scm_make_vector): Fill vectors with the undefined
1380 value, to help make Guile Scheme code more portable to other
1383 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
1384 * symbols.h, tags.h: Doc fixes.
1386 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
1388 * async.c (scm_take_signal): Doc fixes.
1390 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
1392 * numbers.c (scm_divbigint): When the remainder is zero, we don't
1393 want to subtract it from the modulus; we just want to leave it
1396 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
1398 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
1401 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
1403 * throw.c (scm_catch_apply): Finished implementation of
1406 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
1408 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
1410 (scm_init_filesys): set "i/o-extensions" feature.
1413 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
1415 * Makefile.in (root.o): Correct dependencies.
1417 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
1419 * Makefile.in: Added dependency entry for root.o.
1421 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
1422 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
1424 * init.c (scm_start_stack): Set initial root continuation number
1427 * procs.c: New function: scm_thunk_p.
1429 * procs.h: Added declarations of scm_thunk_p.
1431 * root.c: Renamed `call-with-new-root' -->
1432 `call-with-dynamic-root'.
1433 (cwdr): Removed allocation of new root state. This should be done
1434 separately by use of scm_make_root.
1435 (scm_apply_with_dynamic_root): New function: Does what it
1436 sounds like. Needed when spawning threads.
1438 * root.h: Added member last_debug_frame to root state.
1439 Added #include "libguile/debug.h"
1441 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
1442 arguments. The motivation is that code in root.c needs catch
1443 functionality, and we want to avoid code duplication.
1444 New functions: scm_catch, scm_lazy_catch. These are wrappers for
1445 scm_catch_apply. scm_lazy_catch is intended to introduce catch
1446 handlers that run without popping the stack into the dynwind
1449 * throw.h: Added prototypes for scm_catch_apply and
1452 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1454 * root.h (scm_root, scm_set_root): Decouple thread support details
1455 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
1456 SCM_SET_THREAD_LOCAL_DATA.
1458 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
1459 and tortoise scanning loop.
1461 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
1463 * Makefile.in: Rebuild dependencies.
1465 * libguile.h: #include "libguile/print.h" before "smob.h", since
1466 the latter uses the print_state structure.
1468 * throw.c (scm_ithrow): Use the correct variable when checking to
1469 see if a given element of scm_dynwinds is a valid catch.
1471 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
1472 structure, abort; don't just silently ignore the garbage.
1474 * _scm.h: #include "print.h" here, since it seems to be used just
1476 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
1477 strports.c, unif.h: Don't #include "print.h".
1479 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1481 * feature.h (scm_loc_features): Removed external declaration.
1482 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
1484 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1486 * feature.c (scm_init_feature): Added threads feature (needs to be
1487 initialized here, since features doesn't exist when
1488 scm_init_threads is called).
1490 * libguile.h: Added #include "libguile/../threads/threads.h".
1491 (This is a kludge to get thread support working. This should be
1494 * configure.in, acconfig.h: Added flags for thread support.
1496 * scmsigs.c: Define `signal' to be `pthread_signal' if using
1499 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
1500 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
1503 * _scm.h: Added conditional #include "threads.h"
1505 * __scm.h (SCM_ASYNC_TICK): Added call to macro
1506 SCM_THREADS_SWITCHING_CODE.
1508 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
1509 allocate the basic dynamic root object.
1510 (scm_boot_guile): Added call to scm_init_root.
1512 * root.c, root.h: Added root smob.
1513 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
1514 functions: Implements dynamic roots mostly according to spec in
1515 SCM manual. Main difference is that the second argument is a
1516 throw handler rather than an error "thunk".
1518 * root.h: Added declaration of scm_init_root.
1520 * root.c: Added #include "genio.h", #include "smob.h", #include
1521 "pairs.h", #include "throw.h", #include "dynwind.h", #include
1523 (scm_init_root): Added #include "root.x".
1525 * throw.c: Added #include "stackchk.h"
1526 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
1527 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
1528 can be used in scm_call_with_new_root; Added reenabling of stack
1529 checking when catching a throw.
1531 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
1533 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
1535 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
1536 element is not found, as per R4RS.
1538 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1540 * list.c: Doc fixes throughout.
1542 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1544 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
1545 declare the char * to be const. Avoids a warning in rgx.c.
1547 * ports.h: spelling fix.
1549 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
1552 * load.c (scm_sys_try_load_path): throw an error if file not found
1553 (like it says it in NEWS).
1555 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1557 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
1558 PROPS slot to '(), not #f; it's an empty alist.
1560 * throw.h, throw.c: Use SCM_P instead of #if hair.
1562 Remove special support for uncaught throws; see throw.c for
1564 * throw.c (uncaught_throw): New function.
1565 (scm_ithrow): Call uncaught_throw if we don't find a throw
1566 target; don't mess with scm_bad_throw_vcell.
1567 (scm_bad_throw_vcell): Variable deleted.
1568 (scm_init_throw): Don't initialize it.
1570 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
1573 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1575 * numbers.c (scm_istr2int): If the number is short (as most
1576 numbers are), just call scm_small_istr2int to deal with it.
1577 (scm_small_istr2int): New function, created by un-#ifdefing the
1578 non-bignum version of scm_istr2int and renaming it.
1580 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
1582 * load.c (scm_sys_try_load): don't check whether value returned
1583 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
1584 Change the Scheme name from %try-load to primitive-load.
1586 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
1587 Can avoid passing a message, allowing it to be derived in the
1588 error handler (e.g., if we want to throw to the key both from
1591 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
1593 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
1594 references now have a new appearance which is more compact and
1595 also gives a clue about what the target of the reference is.
1596 By setting parameters in the print state, more fancy printing can
1597 be achieved. This is used by the (not yet commited) backtrace
1600 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
1602 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
1605 * print.c: Added #include "struct.h". Removed function
1608 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
1609 scm_iprin1. Removed prototype for scm_prlist.
1611 * arbiters.c (prinarb),
1612 async.c (print_async),
1613 debug.c (prindebugobj, prinmemoized),
1614 eval.c (prinprom, prinmacro),
1615 filesys.c (scm_fd_print, scm_dir_print),
1617 mallocs.c (prinmalloc),
1618 numbers.c, numbers.h (scm_floprint, scm_bigprint),
1619 smob.h (scm_smobfuns),
1620 srcprop.c (prinsrcprops),
1622 unif.c, unif.h (scm_raprin1, rapr1),
1623 variable.c (prin_var): Changed argument `int writing' to
1624 `scm_print_state *pstate'.
1626 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
1627 that it will be called before scm_init_print.
1629 * print.c (scm_prin1): Print states are now allocated when calling
1630 scm_prin1 and then passed around to all printing functions as an
1631 argument. A cache `print_state_pool' enables reuse of print
1633 (scm_make_print_state): New function.
1634 (scm_iprin1): Adaption to print states.
1635 (scm_iprlist): An initial "hare and tortoise" scan brings down
1636 time complexity to O (depth * N). (Better time complexity will be
1637 achieved when the printing code is completely rewritten.)
1639 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1641 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
1642 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
1643 it gets done whether or not the cache variable has a value.
1645 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
1647 Distinguish #f and ().
1648 * __scm.h: #undef SICP.
1649 * pairs.h (SCM_EOL): Delete this definition, equating it with
1651 * tags.h (SCM_EOL): Give it a new definition here; I think I found
1652 the value it used to have. Doc fixes, too.
1654 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
1656 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
1657 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
1658 Lord's implementation of structs, allowing for tail arrays as
1659 described in the manual. Also fixed some bugs. (Both the interface
1660 and the implementation should be improved.)
1662 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
1664 * print.c, print.h: Closures now print like #<procedure foo (x)>.
1665 People who whish to see the source can do `(print-enable 'source)'.
1666 Removed #ifdef DEBUG_EXTENSIONS.
1668 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1670 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
1671 integer (assuming for now accepting an integer is a good thing).
1673 * error.c, fports.c: replace use of %S in lgh_error args with %s.
1674 %S will be used instead for write'ing arguments.
1676 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
1677 asserts. fix a few other asserts.
1678 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
1679 scm_uniform_vector_ref, scm_array_set_x,
1680 scm_dimensions_to_unform_array): change args in
1681 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
1682 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
1683 scm_substring_fill_x): likewise.
1684 gsubr.c (scm_gsubr_apply): likewise.
1685 eval.c (SCM_APPLY): likewise.
1687 * eval.c (4 places): replace scm_everr with lgh_error or
1690 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
1691 scm_memory_error): new procedures.
1692 scm_everr: deleted. can use scm_wta, dropping first two args.
1693 scm_error: convert NULL subr to SCM_BOOL_F.
1695 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
1698 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
1701 * error.c, error.h: new error keys: scm_arg_type_key,
1702 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
1704 scm_wta: reimplement using lgh_error instead of scm_everr.
1706 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
1708 * gdbint.c: scm_lread now has one more argument.
1710 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
1711 scm_port_\1; Added mutator scm_set_port_filename_x (used when
1712 loading source from non-file ports, which, e. g., happens when
1713 using the Emacs interface).
1715 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
1718 * read.c: Added code for recording of positions of source code
1719 expressions; New functions: recsexpr, scm_lreadrecparen;
1720 _scm_make_srcprops --> scm_make_srcprops
1721 (scm_flush_ws): Removed updating of positions counters. This work
1722 is already done by scm_gen_getc
1724 * read.h: Added prototype for scm_lreadrecparen
1726 * print.c: Added #include "alist.h"
1728 * eval.c: Added #include "hash.h"
1730 * eq.c: Added #include "ramap.h"
1732 * options.c: Documentation fixes.
1734 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
1735 (scm_init_srcprop): Adjusted size of initial source-whash. Name
1736 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
1737 --> scm_make_srcprops
1739 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
1740 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
1741 function calls in the definition of the whash access macros.
1743 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
1745 * init.c (scm_boot_guile): Add level of indirection to
1746 scm_boot_guile_1() to ensure that stack base pointer is properly
1747 initialized. There was no guarantee that variable i was the
1748 highest/lowest variable on stack (i.e. the call frame of
1749 scm_boot_guile was not completely protected from gc).
1751 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
1753 * ports.h (scm_port_table): put back file_name, it will be used to
1754 support debugging. Undo related changes in fports.c, ioext.c,
1757 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1759 * ports.h (scm_port_table): remove file_name member for now, it seems
1761 * fports.c (scm_open_file): don't set file_name in PTAB.
1762 (prinfport): don't use file_name in PTAB.
1763 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
1764 * ports.c (scm_add_to_port_table): don't intialize file_name.
1765 (scm_port_file_name): remove for now.
1766 * gc.c (scm_gc_mark): don't mark PTAB file_name.
1768 * fports.h (scm_mkfile): prototype deleted.
1769 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
1771 * debug.c, unif.c: use scm_out_of_range instead of
1772 wta for range errors (ASSERT still needs work).
1774 * error.c, error.h (scm_out_of_range): new procedure.
1776 * error.c, error.h (scm_out_of_range_key): new key.
1778 * posix.c (scm_sync): #else was missing.
1780 * error.c, error.h: append _key to names scm_num_overflow and
1783 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
1784 of consing an empty list.
1785 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
1786 of macros, saves code and string space.
1787 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
1788 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
1789 lower case. Rename scm_syserror_m to scm_syserror_msg.
1790 error.h: prototypes for new procedures.
1792 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
1794 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
1796 * error.c, error.h: setup scm_num_overflow key.
1798 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
1799 Remove definition of SCM_OVSCM_FLOW.
1801 * fports.c (scm_open_file): use SCM_SYSERROR_M.
1803 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
1804 explicit message and args.
1806 * error.c, error.h, __scm.h: change system_error_sym to
1809 * error.c (system_error_sym): remove leading %% from the Scheme name
1812 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
1814 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1816 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
1817 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
1818 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
1819 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
1820 renamed. (These were introduced by unsupervised name
1823 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1825 * print.c: Added code for detection of circular references during
1826 printing. (init_ref_stack, grow_ref_stack): New functions. Added
1827 a hook for printing of closures (accessible via print options).
1828 This leads to a split of calls to scm_iprin1 into two classes:
1829 elementary print operations (e. g. the code which prints a smob)
1830 still use scm_iprin1 while top level calls (like scm_display) use
1831 scm_prin1. scm_prin1 begins by clearing the data structure used
1832 to record reference information.
1834 * print.h: Added declarations of scm_prin1 and scm_prlist.
1836 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
1838 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
1840 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
1842 * error.c (err_head): scm_iprin1 --> scm_prin1
1844 * debug.c: Adjusted header comment.
1848 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1850 * strerror.c: Doc fix.
1852 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1854 * gdbint.c (gdb_read): Now possible to run during GC.
1855 (unmark_port, remark_port): New functions.
1857 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
1859 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
1860 of allocating a new string object. Also, increase size by
1861 the factor 2 instead of 1.5.
1863 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
1865 * __scm.h (SCM_P): Corrected to run under traditional C.
1867 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
1870 * async.c: Calls to scm_sysintern corrected.
1872 * async.h (scm_async_clock): Redundant declaration removed.
1874 * continuations.c (scm_dynthrow): Redundant declaration removed.
1876 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
1877 Definition typos corrected.
1879 * debug.h: Missing declarations of functions in debug.c added
1882 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
1883 Missing declarations to functions in eval.c added.
1885 * filesys.c: Possibly uninitialized variable rv.
1887 * gc.h (scm_object_addr, scm_unhash_name): Missing
1888 declarations of functions defined in gc.c added.
1890 * genio.c: Possible typos str_data -> wstr_data. ???
1892 * genio.c: Possibly unintended shadowing of local variable
1893 `int c' (gotos out of scope of inner `c'). ???
1895 * init.c: Uninitialized `SCM last' may be used.
1897 * ioext.h: (scm_sys_isatty_p): Typo.
1899 * list.h (scm_list_head): Missing prototype for function in
1902 * numbers.c (scm_two_doubles): Changed from extern to static
1903 (is used only within numbers.c).
1905 * numbers.h: Repeated declarations removed.
1907 * ports.h (scm_close_all_ports_except): Declaration for the
1908 function defined in ports.c added.
1910 * posix.h: Missing declarations added.
1912 * procs.h (scm_make_subr_opt): Missing declaration added.
1914 * socket.h (scm_sys_gethost): Missing declaration added.
1916 * socket.h: Redundant declarations removed (they are in fdsocket.h).
1918 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
1919 Missing declarations added.
1921 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
1923 * struct.c: Uninitialized variable `SCM answer' may be used.
1925 * unif.c (l2ra): Declaration prototype.
1927 * unif.c (scm_array_equal_p): Dummy definition removed (it is
1928 defined in ramap.c).
1930 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
1931 Redundant declarations removed (they are in ramap.h).
1933 * variable.h (scm_make_udvariable,
1934 scm_make_undefined_variable): Declaration corrected to
1935 correspond variable.c.
1937 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
1938 Missing declarations added.
1940 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
1942 * Makefile.in (distclean): Don't forget to delete fd.h.
1944 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1946 * fd.h.in, tags.h: Trivial cleanups.
1948 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
1949 marksweep.h just declared functions from gc.c.
1950 * gc.h, libguile.h: Don't #include "marksweep.h".
1951 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
1952 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
1953 dependencies updated.
1955 * libguile.h: Don't #include "files.h"; it's been deleted.
1957 * files.c (scm_sys_delete_file): Moved to filesys.c.
1958 File is now empty; deleted.
1960 * filesys.c: scm_sys_delete_file is now here. Remove
1961 #if's; they seem to rely on remnants of an old portability
1962 regimen. If the problems come up again, solve them properly,
1963 using autoconf. Specifically: Don't test M_SYSV, and #define
1964 remove to be unlink if it's #defined; don't use remove just
1965 because HAVE_STDC_HEADERS is #defined.
1966 * filesys.h: Add declarations for scm_sys_delete_file.
1967 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
1968 files.o, files.h, files.c, and files.x.
1969 * init.c: Don't #include "files.h", and don't call scm_init_files.
1971 Use SCM_P instead of PROTO; the latter intrudes on the user's
1973 * params.h: Deleted; definition of SCM_P moved to...
1974 * __scm.h: ... here, where it replaces PROTO macro.
1975 * libguile.h, smob.h: Don't #include "params.h".
1976 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
1977 smob.h: Fix prototypes accordingly.
1978 * Makefile.in: Update dependencies.
1979 (inner_h_files): Remove params.h.
1981 * gc.c: #include "gc.h"; every module should include its header,
1982 to let the compiler cross-check the declarations against the
1985 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
1986 simpos.h: #include "libguile/__scm.h".
1988 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
1990 * init.c: Don't forget to #include smob.h and init.h.
1991 * Makefile.in: Dependencies updated.
1993 * smob.h: Use PROTO instead of #if __STDC__.
1995 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
1997 * __scm.h: Doc fixes.
1999 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2000 <angles>; this allows `make depends' to work properly.
2002 * libguile.h: #include smob.h and pairs.h before the others; they
2003 define typedefs used by other headers.
2005 C files should #include only the header files they need, not
2006 libguile.h (which #includes all the header files); the pointless
2007 recompilation was wasting my time.
2008 * Makefile.in (all .o dependency lists): Regenerated.
2009 * libguile.h: Don't try to get a definition for size_t here...
2010 * __scm.h: Do it here.
2011 * _scm.h: Since this is the internal libguile header, put things
2012 here that all (or a majority) of the libguile files will want.
2013 Don't #include <libguile.h> here; that generates dependencies on
2014 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2015 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2016 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

2107 * unif.c: Get "unif.h", "feature.h", "strop.h", "sequences.h",

2112 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
2113 * weaks.c: Get "weaks.h".
2115 * stackchk.h: #include "libguile/debug.h",
2117 * print.h, read.h: #include "options.h", since everyone who uses
2118 either of these files will need that.
2120 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2121 anyone who uses this file will need them to define the smob
2122 printing functions. Also, get markers.h, since people will need
2123 to #define the mark functions.
2125 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2126 * ports.h: ... to here.
2128 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2129 don't rely on archaic C default type rules.
2131 * fports.h: #include "libguile/ports.h", since you need that in
2132 order to parse this.
2134 * genio.h: #include "libguile/print.h", because you need that to
2135 parse this; don't bother #including "ports.h", since print.h gets
2138 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2140 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2141 this; it's now a reference to an element of *scm_root.
2143 * debug.h: Don't #include "options.h"; the compiler won't be able
2144 to find that once the headers are installed; instead, #include
2145 "libguile/options.h".
2146 * gc.h: Same, with marksweep.h.
2147 * mbstrings.h: Same, with symbols.h.
2148 * scmhob.h: Same, with _scm.h.
2149 * smob.h: Same, with params.h.
2151 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2152 C files; there's no need for this, and it forces recompilations
2155 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2157 * error.c (scm_error): declare scm_error_callback.
2159 * error.h: prototype for scm_error_callback.
2161 * __scm.h: define lgh_error.
2162 (SCM_SYSERROR): redefine using lgh_error.
2164 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2166 * error.c (scm_error): new procedure.
2168 * error.h: prototype for scm_error.
2170 * Makefile.in (install): install scmconfig.h from the current
2171 directory, not $(srcdir).
2173 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2175 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2176 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2177 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
2178 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
2179 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
2180 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2181 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2182 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2183 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2184 vports.h, weaks.h: #include "libguile/__scm.h", not
2185 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2186 dependencies are within libguile properly.
2188 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2190 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2191 when scmconfig.h doesn't exist.
2193 * load.c (scm_sys_try_load): Correct spelling.
2195 * feature.c (scm_loc_features): Make this static.
2197 * Makefile.in (libpath.h): Omit trailing slash from path. We
2198 shouldn't require it of users, so why put it here?
2200 Move code to initialize and search %load-path from ice-9 to C
2201 code, so we can use the load-path to find the ice-9 boot code;
2202 this makes it easier to run Guile without installing it. See
2203 corresponding changes in guile/Makefile.in.
2204 * feature.c: Move stuff concerned with the load path to load.c.
2205 (scm_compiled_library_path): Deleted.
2206 Don't #include libpath.h here.
2207 * feature.h: Don't mention scm_compiled_library_path.
2208 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2209 <sys/stat.h>, and <unistd.h> (if present).
2210 (R_OK): #define if the system hasn't deigned to.
2211 (scm_loc_load_path): New variable.
2212 (scm_init_load_path, scm_sys_search_load_path,
2213 scm_sys_try_load_path): New functions.
2214 (scm_init_load): Initialize scm_loc_load_path to point to the
2215 value cell of the Scheme %load-path variable.
2216 * load.h: Add declarations for scm_sys_search_load_path,
2217 scm_sys_try_load_path.
2218 * init.c: Call scm_init_load_path.
2219 * Makefile.in (feature.o, load.o): Dependencies updated.
2221 * load.c, load.h: Rewrite using PROTO macro.
2223 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2225 * gc.c (scm_cellp): New function: C predicate to determine if an
2226 SCM value can be regarded as a pointer to a cell on the heap.
2228 * gc.h: Added declaration of scm_cellp.
2230 * gdb_interface.h: New file: The GDB interface header from the GDB
2233 * gdbint.c: New file: GDB interface.
2235 * gdbint.h: New file: GDB interface.
2237 * libguile.h: Added #include <libguile/gdbint.h>.
2239 * init.c (scm_boot_guile): Added scm_init_gdbint.
2241 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2242 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2243 found if object files and source are kept separate).
2245 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2247 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2249 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2251 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2252 TK_SRC_DIR; they're not relevant any more.
2254 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2255 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2257 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2259 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2260 search path, so we can find the <libguile/MUMBLE.h> headers.
2262 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2264 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2265 implicit in the .c.o rule.
2266 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2269 Put the library path in a header file, instead of passing it on
2270 the command line in every compilation.
2271 * Makefile.in (libpath.h): New target.
2272 (feature.o): Depend on libpath.h.
2273 (clean): Delete libpath.h.
2274 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2275 * feature.c: ... #include "libpath.h" here.
2276 * .cvsignore: Ignore libpath.h.
2278 Don't install the unwashed masses of Guile header files in the
2279 main #include path; put most of them in a subdirectory called
2280 'libguile'. This avoids naming conflicts between Guile header
2281 files and system header files (of which there were a few).
2282 * Makefile.in (pkgincludedir): Deleted.
2283 (innerincludedir): New variable; this and $(includedir) are enough.
2284 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
2285 (installed_h_files): Divide this up. Now this variable lists
2286 those header files which should go into $(includedir) (i.e. appear
2287 directly in the #include path), and ...
2288 (inner_h_files): ... this new variable says which files appear in
2289 a subdirectory, and are referred to as <libguile/mumble.h>.
2290 (h_files): List them both.
2291 (install): Create innerincludedir, not pkgincludedir. Put
2292 the installed_h_files and inner_h_files in their proper places.
2293 (uninstall): Corresponding changes.
2294 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2295 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2296 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
2297 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
2298 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
2299 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2300 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2301 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2302 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2303 vports.h, weaks.h: Find __scm.h in its new location.
2304 * __scm.h: Find scmconfig.h and tags.h in their new locations
2305 (they're both "inner" files).
2307 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
2309 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
2311 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2313 * posix.c: Doc fixes.
2315 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
2317 * socket.c: Don't include a prototype for inet_aton; just use a
2318 K&R style declaration, to avoid warnings but minimize the chance
2319 of conflicts with the system.
2321 On NextStep, <utime.h> doesn't define struct utime, unless we
2322 #define _POSIX_SOURCE before #including it.
2323 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
2324 * acconfig.h: New comment text for above CPP symbol.
2325 * configure.in: Call it.
2326 * posix.c: #define _POSIX_SOURCE if it seems necessary.
2328 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
2330 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
2331 testing for __EMX__.
2333 * posix.c: #include <libc.h>, if it exists.
2335 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
2336 don't even know if the latter exists.
2338 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
2339 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
2340 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
2342 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
2344 (scm_init_posix): Use them when initializing the Scheme constants
2347 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2349 * Makefile.in (libdir, includedir, bindir): Use the
2350 autoconf-supplied values, instead of deriving them ourselves.
2351 (pkgincludedir, datadir, pkgdatadir): New variables.
2352 (install, uninstall): Put the header files in a special
2353 subdirectory, not in the main search path.
2355 * Makefile.in (ALL_CFLAGS): Provide the proper value for
2356 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
2358 * Makefile.in (IMPLPATH): Deleted; never used.
2360 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
2361 on the Tcl/Tk source any more.
2362 (INCLUDE_CFLAGS): Remove references to the above.
2364 * Makefile.in (version.o): Corrected dependencies.
2366 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
2368 * libguile.h: #include "version.h"
2370 * init.c (scm_boot_guile): Call scm_init_version.
2371 * gscm.c (gscm_run_scm): Call scm_init_version.
2373 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
2374 GUILE_VERSION): AC_DEFINE these.
2375 (acconfig.h): #undef the above symbols.
2377 * Makefile.in (libobjs): Add version.o.
2378 (installed_h_files): Add version.h.
2379 (c_files): Add version.c.
2380 (gen_c_files): Add version.x.
2381 (version.o): New rule.

2391 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
2392 weaks.o): Add version.h to dependency lists.
2393 (markers.o): Remove duplicate rule.
2395 * version.h: New file.
2397 * version.c: New file.
2399 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2401 * symbols.c (scm_strhash): scm_downcase is now a function, not an
2402 array; use it appropriately. Since GCC is quite happy to
2403 subscript functions, it never warned us about this; we should use
2404 -Wpointer-arith in the future. I guess we never tested
2407 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2409 * socket.c: Doc and copyright fixes.
2411 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2413 * debug.c: Fixed and improved gdb support.
2415 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2417 * socket.c: Added declaration of inet_aton to avoid compiler
2418 warning. (Hope this solution is correct.)
2420 * stime.c: Added declaration of ftime. (This is missing in
2423 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
2425 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2427 * Makefile.in (c_files): add strerror.c.
2429 * strerror.c: new file from Emacs' sysdep.c.
2430 maybe configure should also check for sys_errlist.
2432 * configure.in (AC_REPLACE_FUNCS): add strerror.
2434 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2436 * debug.c (scm_init_debug): Added initialization for
2437 scm_evaluator_traps.
2439 * debug.h, debug.c: Various name changes.
2440 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
2441 "debug-options-interface". See commentary in options.c.
2443 * options.h, options.c: Options now have documentation strings.
2444 Also added a long explanatory commentary.
2446 * eval.c, print.h, print.c, read.h, read.c: Modifications to
2449 * gscm.c, init.c, root.c, throw.c: Bug fixes:
2450 last_debug_info_frame is now updated in all cases.
2452 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
2455 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2457 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
2458 Added option STACK_CHECKING.
2460 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
2462 * Makefile.in: Added {debug,options,srcprop}.{h,c}
2464 * __scm.h: Removed symbols for debugging support.
2466 * acconfig.h: Added symbols for debugging support.
2468 * configure.in: Added user option for debugging support.
2469 --enable-debug will include the debugging code into libguile.a.
2471 * continuations.c (scm_make_cont): Enlarged the #if 0 around
2472 scm_relocate_chunk_to_heap.
2474 * debug.c: New file: low-level debugging support. It also
2475 includes support for debugging with gdb. (The extensions to gdb
2476 are written by Per Bothner at Cygnus.)
2478 * debug.h: New file: low-level debugging support.
2480 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
2481 argument pairs. Extensive modifications to the debugging
2482 evaluator. Added "SECTION:" commentaries to clarify what happens
2483 when, during double compilation. Renamed EVALIMP --> EVALIM.
2484 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
2485 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
2486 the beginning of the file. New procedure: scm_unmemocopy.
2487 Added some global state variables needed by the debugging
2488 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
2489 check_entry, check_apply, check_exit, debug_options and
2490 evaluator_traps. New acro: undefine.
2492 * eval.h: Renamed EVAL --> XEVAL.
2494 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
2495 --> scm_make_weak_key_hash_table.
2497 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
2498 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
2500 * libguile.h: Conditionally include debug.h
2502 * objprop.c (scm_object_properties, scm_set_object_properties_x):
2503 scm_object_properties shouldn't return handle. `handle' now gets
2504 initialized in scm_set_object_properties_x. scm_object_properties
2505 doesn't any longer create an entry in scm_object_whash.
2507 * options.c: New file: handling of run time options.
2509 * options.h: New file: handling of run time options.
2511 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
2513 * print.c: New procedure: scm_print_options
2515 * print.h: Defines for print options.
2517 * read.c: New procedure: scm_read_options
2519 * read.h: Defines for reader options.
2521 * root.h: Added scm_source_whash among scm_sys_protects.
2523 * srcprop.c: New file: source properties.
2525 * srcprop.h: New file: source properties.
2527 * throw.c (jbsmob): Jump buffers are now correctly allocated.
2528 (Bug found by A. Green.)
2530 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2532 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2534 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
2536 * libguile.h: #include "objprop.h"; I guess this was forgotten.
2538 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
2539 and should be called by the final client.
2541 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
2543 * gc.h: Use the PROTO macro when declaring functions.
2544 * gc.c: Use the PROTO macro when declaring static functions.
2545 Remove the CPP hair around function definitions.
2547 * gc.c (scm_init_storage): Initialize scm_asyncs.
2549 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
2550 preprocessor symbol; "__scm.h" is where it might get #defined.
2551 * __scm.h: Similar: #include <scmconfig.h> before testing
2554 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
2556 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
2558 * init.c (scm_boot_guile): Add init_func argument; call
2559 (*init_func) instead of calling scm_appinit; it's ucky to
2560 hard-code names for the user's procedures.
2561 * init.h (scm_boot_guile): Adjust declaration.
2563 * __scm.h (PROTO): New macro, for declaring functions with
2566 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
2567 eliminate all the __STDC__ conditionals.
2568 (scm_boot_guile): Add declaration.
2569 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
2570 Remove __STDC__ conditionals around function definitions; the
2571 declarations in init.h will provide the same information, more
2574 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
2575 complain about it in the error message; the error message is
2576 adequate without that note, and there's nothing the user can do
2579 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
2581 * Makefile.in (ancillary): Drop def.sed.
2583 * posix.c (scm_init_posix): Use numeric values, rather than
2584 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
2585 F_OK. The symbols aren't available on some systems, and I'm
2586 pretty sure their values are fixed by common widespread practice.
2587 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
2589 More functions unavailable on some systems.
2590 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
2591 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
2593 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2594 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
2595 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
2596 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
2597 stub that signals an error as the #else.
2599 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
2601 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
2603 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
2605 * unif.c: include ramap.h.
2607 * read.c (endif): case_insensative_p renamed case_insensitive_p.
2609 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
2611 * ports.c: include sys/ioctl.h.
2613 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
2615 * configure.in: check for sys/ioctl.h.
2617 * ports.c: include <malloc.h> not "malloc.h".
2619 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2621 * fports.c: remove ttyname and tmpnam declarations.
2623 * posix.c: fewer ttyname declarations.
2625 * fports.c: include <string.h> not "string.h".
2627 * init.c, ioext.c: include string.h and unistd.h.
2629 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2631 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
2632 genio.c, simpos.c, vports.c: include string.h.
2634 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
2636 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
2638 (scm_addr_buffer_size): change type from scm_sizet to int.
2639 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
2640 from scm_sizet to int.
2642 * error.c: include unistd.h.
2644 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
2647 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
2649 * __scm.hd, def.sed: deleted.
2651 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
2653 Changes for NeXT, suggested by Robert Brown.
2654 * configure.in: Call AC_TYPE_MODE_T.
2655 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
2656 NeXT. Put header file list in alphabetical order.
2657 * configure, scmconfig.h.in: Regenerated.
2658 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
2660 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
2663 * acconfig.h: New file, providing documentation for the CPP
2664 symbols defined in configure.in
2665 * acconfig-1.5.h: Removed; superceded by the above.
2667 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
2669 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
2671 * fports.c (scm_open_file): don't return #f, throw error.
2673 * ioext.c (fileno): renamed from %fileno.
2674 (soft-fileno): deleted.
2676 * ports.c (scm_port_revealed): don't need to check for -1 from
2678 (scm_set_port_revealed_x): return unspecified, not #f.
2680 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
2682 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
2684 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
2686 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
2688 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2690 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
2691 This is necessary on Ultrix, and doesn't hurt portability.
2693 * Makefile.in (dist-dir): New target, implementing a new dist system.
2694 (installed_h_files): Put in alphabetical order.
2695 Remove duplicate entries for markers.h and unif.h.
2696 (c_files): Remove duplicate entries for markers.c.
2697 (ancillary): Renamed from anillery; all uses changed. Remove
2698 PLUGIN; it's a directory, and needs special treatment in dist-dir.
2699 Remove all the ../doc/* files; doc/Makefile.in handles that.
2701 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
2703 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
2704 every if must have an else, or else the whole command has a
2705 non-zero exit code whenever the if's condition is false.
2707 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
2709 * posix.c: include string.h.
2711 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2713 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
2716 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
2717 Remove leading % from scheme names.
2718 Do not return error values, call SCM_SYSERROR or similar.
2720 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
2722 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
2724 * struct.c (scm_init_struct): new file.
2726 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
2728 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
2729 (scm_list_head): added list-head for rapidly chopping argument
2730 lists off of longer lists (and similar).
2732 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
2734 * objprop.c (scm_object_property): assq the cdr of the whash
2735 handle for obj, not the handle itself.
2737 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
2739 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
2740 weak hash tables last of all marking to avoid an obscure gc bug.
2741 WARNING: circular lists stored in a weak hash table will hose us.
2743 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
2745 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
2746 new functions similar to scm_substring_move_left_x and
2747 scm_substring_move_right_x.
2749 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
2751 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
2754 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
2756 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
2758 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
2760 * strports.c (scm_strprint_obj): convenience function. C for
2761 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
2763 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
2764 removed to a separate library
2766 * init.c (scm_boot_guile): copied from guile-tcl.c.
2767 Initialization specific to tcl interpreters removed.
2769 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
2771 * ports.c (scm_ports_prehistory): size malloced here doesn't
2772 matter so long as it is non-0 (got rid of "* 4").
2774 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
2776 * gscm.h: gscm_mkarray eliminated (presumably was not being used
2777 since its definition was bogus).
2779 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
2781 * mallocs.[ch]: back again (for rx at least).
2783 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
2785 * ports.c: removed functions relating to the mapping between ports
2786 and descriptors. (That stuff is unix-specific and should be collected
2787 in a separate library).
2789 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
2790 (Tom Mckay@avanticorp.com)
2792 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
2794 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
2795 handled correctly (SCM_FREEP was applied to them) -- test for
2796 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
2797 being overwritten with #f. (brown@grettir.bibliotech.com)
2799 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
2801 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs

2804 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
2806 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
2807 keys and weak values confused).

2811 * list.c (scm_last_pair): map '()=>'()
2813 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>

2816 Generalized assoc and hash-table functions.
2817 Factored pairs.c into multiple files.
2819 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
2821 * gscm.c (gscm_run_scm): got rid of objprop.
2823 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
2825 * genio.c (scm_getc):
2826 NOTE: fgetc may not be interruptable.
2828 * procprop.c (scm_stand_in_scm_proc):
2829 NOTE: don't use a alist here.
2830 (scm_set_procedure_properties_x): fix type checking throughout this file.
2832 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
2834 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
2835 after freeing part of the port table.
2837 Thu Feb 29 16:21:17 1996 Tom Lord <lord@beehive>
2839 * strports.c (scm_mkstrport):
2840 * vports.c (scm_make_soft_port): allocate a port table entry
2841 (possibly triggering gc) before setting the tag of the corresponding
2844 * pairs.c (scm_delq_x): never throw an error.
2846 * vectors.c (scm_make_vector): made the default vector fill argument
2847 into '() (much more useful than the previous value, "#unspecified")
2849 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
2851 * ports.c (scm_add_to_port_table): Added fields
2852 to port table entries: file_name, line_num, col.
2853 Update these in open_file, gen_getc and gen_ungetc.
2854 Added procedures to access those fields.
2856 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
2858 * procs.c (scm_make_subr_opt): new entry point for making
2861 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
2863 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
2865 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
2867 * numbers.c (scm_exact_p): This function no longer
2868 implements "integer?".
2870 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
2872 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
2873 (scm_gc_stats): return an assoc of useful data. Replaces "room"
2874 and the stats reporting formerlly built into repl.
2876 * repl.[ch]: removed.
2877 GC statistics keeping moved to gc.c.
2878 Other statistics keeping can be done from Scheme.
2879 REPLS are now written in Scheme.
2881 Wed Feb 21 10:28:53 1996 Tom Lord <lord@beehive>
2883 * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky
2884 conservatively marked objects).
2886 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
2888 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
2890 * feature.c (scm_compiled_library_path): moved here from repl.c.
2891 This file is for stuff relating specifically to Scheme libraries
2894 * eval.c (scm_m_define): don't give warning about redefinition, don't
2897 NOTE: this should throw a resumable exception with parameters --
2898 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
2900 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
2902 * error.c: scm_warn eliminated.
2904 * read.c (scm_lreadr): extra right paren gets an error, not a warning.
2906 * repl.c, marksweep.c, gc.c (various):
2907 lose exit_report, growth_mon.
2909 * gscm.c: got rid of verbosity functions.
2911 Tue Feb 20 00:19:10 1996 Tom Lord <lord@beehive>
2913 * throw.c (scm_ithrow): guard against the bad-throw hook changing
2914 between the call to procedurep and use.
2916 * error.c (scm_everr):
2918 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,

2964 initialization to fix a race condition.
2966 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

2990 set the multi_byte flag correctly in symbols. This is wrong.
2991 intern_obbary_soft and msymbolize should take an extra parameter.
