1 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
6 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
8 * unif.c (scm_array_set_x): minor change to argument error checking.
10 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
12 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
13 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
14 They should only be included in the library at configure.in's
16 (libguile_la_LDADD): Include the appropriate .lo files here.
17 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
18 so we know when to build them (and their .lo bretheren).
19 * configure.in (LIBLOBJS): New substituted variable. We let
20 configure decide which .o files to include in LIBOBJS, and then
21 put the corresponding list of .lo files in LIBLOBJS. The latter
22 is what we pass to libtool.
23 * Makefile.in, configure: regenerated.
25 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
27 * symbols.c (scm_sysintern0): New function. Contains the core of
28 old scm_sysintern but doesn't take a second value argument.
29 (scm_sysintern): Now uses scm_sysintern0.
30 (scm_sysintern_no_module_lookup): Renamed to
31 scm_sysintern0_no_module_lookup and doesn't take a second value
34 * symbols.h (scm_sysintern0: Added declaration.
36 * options.c (scm_init_opts): Use scm_sysintern0 instead of
37 scm_sysintern when interning option keys. Otherwise we risk
38 destroying the values of already interned variables.
40 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
41 scheme-level boolean (use SCM_NFALSEP).
43 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
45 (scm_backtrace): New function. (C version of old function from
46 boot-9.scm) Motivation: Make it possible to display backtraces
47 without depending on boot-9.scm. (I'm uncertain if this
48 motivation is good enough...)
50 * root.h (scm_root_state): Add member the_last_stack_var.
51 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
53 * root.c (mark_root): Mark scm_the_last_stack_var.
55 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
58 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
60 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
61 1. mark_lazy_catch didn't mark the smob.
62 2. Both functions above have standard variants:
63 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
64 free_lazy_catch --> scm_free0.
66 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
68 * throw.c (scm_internal_lazy_catch): New function.
69 (scm_lazy_catch): Rewritten to use it.
70 (scm_ithrow): Handle the new lazy catch representation.
71 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
72 that doesn't have a jmpbuf is a lazy catch clause.
73 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
74 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
75 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
77 (scm_init_throw): Register the new lazy-catch smob type.
78 * throw.h (scm_internal_lazy_catch): decl for new function.
80 * throw.c (scm_internal_catch): Doc fixes.
82 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
83 configure.in. Including this might cause problems if applications
84 that link against libguile include their own copies of alloca, but
85 if they're using autoconf, they should be adding libguile to LIBS
86 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
87 the copy in libguile, and things will be okay. (I think.)
89 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
91 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
93 strop.h: move prototypes too.
95 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
97 * posix.c (scm_init_posix): don't intern EINTR since it's now done
100 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
101 etc. I deleted them from filesys.c long ago, but didn't
102 notice they were here too (although ineffective since
103 sys/stat.h wasn't included).
105 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
107 * eval.c: Don't define alloca in GCC case. gcc will automatically
108 use __builtin_alloca if appropriate.
110 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
112 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
113 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
114 that values of automatic variables are preserved. See comments
115 for safe_setjmp for details.
117 Change from Thomas Morgan:
118 * variable.c: Include eq.h.
119 (var_equal): New function.
120 (variable_smob): Use var_equal as the discriminator for variables.
122 * throw.c (s_throw): Remove extraneous declaration.
124 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
125 * eval.c: Add necessary CPP cruft to support that.
126 * configure, Makefile.in, scmconfig.h.in: regenerated.
128 Change from Thomas Morgan:
129 * procprop.c (scm_procedure_properties): Convert the Scheme
130 boolean returned by scm_procedure_p into a C boolean before using
131 it as a condition for SCM_ASSERT.
132 (scm_procedure_property): Likewise.
134 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
135 indications of Unixness.
138 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
140 * * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
142 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
144 * read.c (scm_lreadr): use scm_misc_error to improve one of the
145 "unknown # object" error messages.
147 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
148 (scm_i_index) and declare it static. Add a 'direction' argument
149 to indicate what way the search should go.
150 (scm_i_index): throw out-of-range error instead of wrong-type-arg
152 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
153 strop.h: remove scm_i_index, scm_i_rindex prototypes.
155 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
157 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
159 * * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
160 to avoid clash with various scsh forks.
162 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
164 The following two changes (ramap.c, throw.c) are motivated by the
165 apparent unportability of forward declarations of static arrays of
166 the form `static foo bar[];'.
168 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
169 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
171 * throw.c (scm_throw): Moved above scm_ithrow.
173 * options.h: Removed the extern declarations of scm_yes_sym and
174 scm_no_sym since these are static.
176 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
178 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
180 * Makefile.am: remove AWK=@AWK@.
181 Add a rule for generating errnos.list.
182 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
184 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
185 don't extract errnos, just set a variable (avoids the
186 need to recompile error.c just because configure is run.)
188 * unif.h: update prototypes.
189 * unif.c (scm_uniform_array_read,write): change the offset and
190 length arguments to start and end, for consistency.
192 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
194 * ioext.h: update prototypes.
195 * * ioext.c (scm_read_delimited_x): replaces scm_read_line and
196 scm_read_line_x, it's a more general procedure using an
197 interface from scsh. read-line and read-line! are now defined
199 * Note that the new read-line trims the terminator
200 by default, previously it was appended to the returned string. An
201 optional argument specifies how to process the terminator (scsh
202 compatible). For the old behaviour: (read-line port 'concat).
203 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
204 returns a pair, but is converted to multiple values if the scsh
207 socket.h: update prototypes.
208 * socket.c (scm_recvfrom): for consistency with other procedures,
209 take start and end as separate optional arguments.
210 * (scm_recv, scm_recvfrom): don't allow the second argument
211 to be a size, only a buffer. Change the scheme names to
212 recv! and recvfrom!. Don't return the buffer.
214 * ioext.h, posix.h: move prototypes too.
215 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
216 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
217 "read.h" and "unif.h".
218 * ioext.c: include "chars.h"
220 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
222 * dynl.c: The dynamic linking and module registration functions
223 are now defined even when dynamic linking is not available for the
224 host system. Some of their functionality can be done without
225 dynamic linking; when it's really needed, they throw errors.
227 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
229 * configure.in: Only define DYNAMIC_LINKING when one of the system
230 dependent functions is detected.
231 * dynl.c (scm_dynamic_func): New function to get the address of a
232 function in a dynamic object.
233 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
234 produced by scm_dynamic_func as the thing to call.
236 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
238 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
239 (scm_register_module_xxx, scm_registered_modules,
240 scm_clear_registered_modules): New functions.
242 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
244 * symbols.c (scm_sysintern): Renamed to
245 scm_sysintern_no_module_lookup.
246 (scm_sysintern): New function to take the place of the old
247 scm_sysintern. It uses the current toplevel lookup closure to give
248 the symbol its value. This is a temporary hack to put packages
249 like gtcltk into their own module.
250 (scm_can_use_top_level_lookup_closure_var): New variable to tell
251 us whether `scm_top_level_lookup_closure_var' has been initialized
253 * eval.c (scm_init_eval): Set it.
255 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
257 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
258 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
260 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
262 * (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
263 scm_sys_dup): deleted: FD capability will be added to other
265 * Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
266 scm_fd_free, fd_smob, scm_intern_fd.
267 * (scm_open): renamed from scm_sys_open. Return a port instead of
268 an FD object. Make the mode argument optional.
269 * (scm_sys_create): deleted, it's just a special case of open.
270 (scm_init_filesys): move interning of constants O_CREAT etc.,
271 here (were previously using SCM_CONST_LONG macro).
272 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
274 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
275 include "fports.h" and <stdio.h>
276 (scm_stat, scm_select): don't support FD objects.
278 * error.h: adjust scm_syserror_msg prototype.
279 * error.c (scm_syserror_msg): take an extra argument for errno.
280 Using the global value didn't always work, since it could be
281 reset by procedure calls in the message or args arguments.
283 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
284 I don't understand why the check was there (and what about the
287 * strop.c (scm_string_copy): allow shared substrings to be copied.
289 * unif.h: corresponding change to prototypes.
290 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
291 recognize two new optional arguments: offset and length. Allow
292 the port argument to be an integer (file descriptor, for scsh).
293 Include <unistd.h> for "read" prototype.
295 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
297 * socket.c: don't include filesys.h.
299 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
301 * Makefile.am: add AWK=@AWK@ (?)
303 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
305 Add a rule to generate errnos.c from errnos.
306 * error.c (scm_init_error): include errnos.c.
307 * errnos_cnvt.awk: new file, converts the list of errno codes to
309 * errnos_get.c: new file.
310 * errnos.default: new file, contains errnos to try if they can't
311 be extracted from errno.h.
312 * configure.in: if using GCC, try and extract errno codes from
316 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
318 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
319 * Makefile.am: Made libguile into a libtool library.
320 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
321 Set libtool_libs to indicate that libguile is a libtool library.
322 See guile/ChangeLog for details.
323 * .cvsignore: ignore "*.lo", the libtool library objects.
325 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
327 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
328 use htons in getservbyport argument.
330 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
332 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
333 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
336 * objprop.c (scm_object_property): No need to take the CDR of the
337 value returned by scm_object_properties, since Aug 20 change.
339 * configure.in: When checking for struct linger, #include
340 <sys/types.h> as well as <sys/socket.h>. I've never known
341 <sys/types.h> to cause any portability problems, and Solaris's
342 <sys/socket.h> needs it.
343 * configure: Rebuilt.
345 I think the Sun compiler has chosen a perverse way to interpret
346 ANSI declarations combined with K&R definitions. We'll
347 appease it a little bit. But when it invades France, we fight.
348 * print.c (scm_iprlist): Change 'tlr' argument to an int.
349 * print.h (scm_iprlist): Here too.
350 * numbers.c (scm_divbigdig): Change definition to match
351 declaration in numbers.h.
352 * unif.c (scm_makflo): Change definition to match declaration in
355 * init.c (scm_boot_guile): Don't return the value of
356 scm_boot_guile_1. This function doesn't return a value;
357 scm_boot_guile_1 doesn't return a value (or return at all).
359 * eval.c (unmemocopy): Add a semicolon to appease the Sun
362 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
363 compile. I have a feeling this function is a bad idea anyway ---
364 one should always test for features, not systems.
366 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
367 semicolons. Only pure luck kept this from being noticed earlier.
369 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
371 * socket.c (scm_recvfrom): Added missing semicolon.
373 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
375 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
376 the buffer and start and end positions for scsh networking
379 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
381 * configure.in: Revert previous change to this file; the problem
382 is due to transient automake weirdness.
383 * configure: Rebuilt.
385 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
386 PLUGIN/guile.libs. configure generates the latter from the former.
387 * Makefile.in: Rebuilt.
389 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
390 need this if we install scripts, like guile-snarf.
391 * configure: Rebuilt.
393 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
395 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
397 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
399 * socket.c (scm_addr_vector): fix faulty scm_listify.
401 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
403 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
404 style block comment is no longer considered an error.
406 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
408 * PLUGIN/guile.libs.in: New file.
409 * PLUGIN/guile.libs: Removed from repository.
410 * configure.in: Create PLUGIN/guile.libs from
411 PLUGIN/guile.libs.in. This is for including additonal libraries
412 needed for dynamic linking.
413 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
414 instead of PLUGIN/guile.libs.
416 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
418 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
420 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
421 occurrences of the given element from the list, not just the
422 first. This is how the Emacs Lisp functions behave, how the
423 analogous Common Lisp functions behave, and (I believe) how the
424 older Maclisp functions worked. I realize that this change may
425 break code, but it seemed better to break it before the Guile
428 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
429 Their prototypes were already present in gc.h, but they weren't
431 (scm_init_storage): Initialize scm_protects.
432 * root.c (scm_protects): New element of scm_sys_protects.
434 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
436 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
438 * libguile.h: Added #include "libguile/net_db.h".
440 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
441 30 change. That file is only meant for communication between the
442 configuration process and load.c. If code linked against libguile
443 wants to get at the paths mentioned in libpath.h, it can call
444 functions declared in load.h.
446 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
448 * libguile.h: Removed #include "libguile/fdsocket.h"
450 * net_db.c: Added #include <sys/socket.h>.
452 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
454 * filesys.c (scm_input_waiting_p): use select in preference to
455 FIONREAD, since the latter doesn't detect EOF.
456 Throw error if neither select nor FIONREAD available.
458 * socket.c (scm_connect): take a port, not a fd object.
459 (scm_fill_sockaddr): throw an error if fam is not recognised.
460 (scm_bind): use scm_fill_sockaddr.
461 (scm_listen): take a port, not a fd object.
462 (scm_accept): take and return a port. return #f in the car if
464 (scm_sock_fd_to_port): new procedure.
465 (scm_socket): use scm_sock_fd_to_port.
466 (scm_addr_vector): throw error if unrecognised address type.
467 take an extra argument with the calling procedure name.
468 (scm_getsockname): take a port. return #f if address can't be got.
469 (scm_getpeername): take a port. return #f if address can't be got.
470 (scm_recvfrom): take a port. return #f for address component if can't
472 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
473 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
475 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
477 * throw.c (scm_internal_catch): Make body funcs and handler funcs
478 use separate data pointers, to allow them to be designed
479 independently and reused.
480 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
481 Renamed from catch_body, catch_handler, and uncaught_throw; made
483 (struct scm_catch_body_data): Renamed from catch_body_data; moved
485 (scm_catch): Use the above.
486 (scm_throw): Don't bother printing a message for an uncaught
487 throw; we establish a default handler in init.
488 * throw.h (scm_internal_catch): Prototype updated.
489 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
491 (struct scm_body_thunk_data): New structure, used as data
492 argument to scm_body_thunk.
493 * init.c (struct main_func_closure): New structure, packaging up
494 the data to pass to the user's main function.
495 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
496 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
497 scm_internal_catch to establish a catch-all handler, using
498 scm_handle_by_message. This replaces the special-case code in
500 (invoke_main_func): Body function for scm_internal_catch; invoke
501 the user's main function, using the main_func_closure pointer to
502 decide what to pass it.
503 * root.c (struct cwdr_body_data): Remove handler_proc member.
504 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
505 (cwdr_handler): Removed.
507 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
509 * socket.h (SCM_P): update bind prototype.
510 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
512 (scm_socket): return a port, not a file descriptor object.
513 include "fports.h" and <unistd.h>
514 (scm_bind): take a port, not a file descriptor object.
515 take an extra argument for address args.
517 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
518 INADDR_NONE, INADDR_LOOPBACK.
520 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
522 * init.c: include net_db.h and not fdsocket.h.
523 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
525 * Makefile.am: corresponding changes.
526 * socket.h: renamed from fdsocket.h, fix names.
527 * net_db.h: renamed from socket.h, fix names.
528 * socket.c: renamed from fdsocket.c.
529 remove _sys from procedure names.
530 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
531 add "socket" to features list.
532 * net_db.c: renamed from socket.c.
533 remove _sys from procedure names.
534 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
535 add "net-db" to features list.
536 include "net_db.h". don't include <sys/socket.h> or
539 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
541 * tags.h (scm_tags): Removed comma at end of last enumerator.
543 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
545 Don't use GCC extensions to allocate space for debugging frames.
546 (Here he goes again! Why do we put up with this?!)
547 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
548 an scm_debug_info structure, not an in-line array of them. Add
549 'info' member, to say how many vect elements we've used, for eval
551 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
552 a new variable debug_info_end to mark the end of vect, instead of
553 the address of the 'info' pointer itself.
554 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
555 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
556 (SCM_APPLY): Explicitly allocate space for debug.vect.
557 * debug.c (scm_m_start_stack): Same, for vframe.vect.
558 * stacks.c: Adjusted for new debug frame structure.
559 (RELOC_INFO, RELOC_FRAME): New macros.
560 (stack_depth, read_frames): Use them, and new scm_debug_frame
561 element 'info', instead of magically knowing that eval frames have
562 an info pointer sitting after vect.
563 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
565 (scm_init_stacks): Formatting tweaks.
567 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
569 Give GCC more control flow information, so it can be sure that
570 variables aren't used uninitialized.
571 * error.h (scm_error, scm_syserror, scm_syserror_msg,
572 scm_sysmissing, scm_num_overflow, scm_out_of_range,
573 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
574 scm_misc_error): Tell GCC that these functions never return.
575 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
576 out the field type, call abort if SCM_ASSERT returns, to placate
578 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
579 scm_wta ever returns. We can't handle this case anyway, and this
580 gives the optimizer more information.
581 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
582 scm_wta ever returns.
584 In some cases, the code is fine, but GCC isn't smart enough to
585 figure that out; this usually happens when one variable is only
586 initialized and used when a particular condition holds true, and
587 we know that condition will never change within a given invocation
588 of the function. In this case, we simply initialize the variables
589 to placate the compiler, hopefully to a value which will cause a
590 crash if it is ever actually used.
591 * print.c (scm_iprin1): Initialize mw_pos.
592 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
593 * throw.c (scm_ithrow): Initialize dynpair.
594 * unif.c (scm_uniform_vector_ref): Initialize cra.
595 * struct.c (init_struct): Initialize prot.
596 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
598 * strports.c (scm_eval_0str): Don't return uninitialized garbage
599 if EXPR contains no expressions.
601 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
603 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
604 cause an infinite loop (???). So much for the algebraic
605 equivalency of variable-sized arrays and alloca...
607 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
609 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
610 a SCM boolean, not a C boolean.
612 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
614 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
615 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
616 rules for raising scm_mtrigger. Previously, unfortunate but not
617 unlikely circumstances could result in almost constant invokation
618 of the gc. Now, this situations should be less likely, but they
619 are not prevented completely.
621 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
623 * numbers.c (scm_fuck): Procedure removed; looks like old test
625 * numbers.h: Prototype removed.
627 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
629 * debug.h (scm_debug_frame): Change `vect' member from an in-line
630 array to a pointer, to match my Nov 21 change in eval.c.
632 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
634 * libguile.h: Added #include "libguile/backtrace.h", #include
637 * strings.c (scm_string scm_make_string scm_string_ref
638 scm_string_set_x scm_string_equal_p scm_string_append):
639 Bugfix according to scm patch from Aubrey Jaffer:
640 Corrected long-standing
641 (not (eqv? (integer->char 128)
642 (string-ref (make-string 1 (integer->char 128)) 0)))
643 bug found by John Kozak <jk@noontide.demon.co.uk>.
645 * strports.c, strports.h: Make scm_eval_0str return the value of
646 the last expression evaluated (previously, it returned void).
648 * strports.c, strports.h: New function: scm_read_0str. Does what
651 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
653 * simpos.c (scm_getenv): return #f if string can't be found in the
654 environment instead of throwing an exception, for compatibility
655 with numerous other systems.
657 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
659 * Makefile.am (.c.x): Use guile-snarf.
660 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
662 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
664 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
666 * backtrace.c (scm_display_error_message): Made non-static, and
667 renamed from display_error_message.
668 * backtrace.h (scm_display_error_message): Added extern decl.
669 * throw.c (uncaught_throw): Use it to display the error message.
671 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
673 * inet_aton.c: Use #if 0, not #ifdef 0.
675 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
677 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
678 to convert the returned value.
679 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
682 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
684 Add new interface to catch/throw, usable from C as well as
686 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
687 (scm_internal_catch): New function, replaces...
688 (scm_catch_apply): Deleted.
689 * throw.c (scm_catch_apply): Deleted; replaced with a more general
690 mechanism which is a bit more code, but can be used nicely from C
691 and implement the Scheme semantics as well.
692 (scm_internal_catch): This is the replacement; it's named after
693 the analogous function in Emacs.
694 (scm_catch): Reimplemented in terms of the above.
695 (struct catch_body_data, catch_body, catch_handler): New
696 functions, used by scm_catch.
697 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
698 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
699 support for new cwdr.
701 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
704 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
706 * acconfig.h: Added DYNAMIC_LINKING symbol.
707 * configure.in: Add option and checks for dynamic linking.
708 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
709 dynl.h: New files for dynamic linking support.
710 * Makefile.am (libguile_a_SOURCES):
712 (modinclude_HEADERS): Added "dynl.h".
713 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
715 * init.c (scm_boot_guile_1): Call
716 scm_init_dynamic_linking to initialize dynamic linking support.
718 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
720 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
721 (as we Schemers say). It needs to be global, so that I can tweak
722 it for the proper operation of unexec.
723 (scm_boot_guile_1_live): New variable, see above.
725 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
727 * guile-snarf.sh: Removed.
728 * PLUGIN/guile.libs: Added dependency for -lm.
729 * acinclude.m4: Renamed from aclocal.m4.
730 * PLUGIN/greet: Removed.
731 * Makefile.am, aclocal.m4: New files.
732 * configure.in: Updated for Automake.
734 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
736 * eval.c (scm_definedp): Use top_level_lookup_closure_var
737 and not top_level_lookup_thunk_var.
739 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
741 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
743 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
745 * eval.c (scm_definedp): Incompatibly changed to be a builtin
746 Scheme function, instead of syntax. Single argument is now a
749 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
751 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
752 scm_ra_divide): Properly terminate statements passed as arguments
753 to IVDEP macros. (Thanks to Bernard Urban.)
755 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
756 with non-constant sizes. (Thanks to Bernard Urban.)
758 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
760 It's an "eval closure", not an "eval thunk." A thunk is a
761 function of no arguments.
762 * root.h (struct scm_root_state): Renamed
763 top_level_lookup_closure_var from top_level_lookup_thunk_var.
764 (scm_top_level_lookup_closure_var): Renamed from
765 scm_top_level_lookup_thunk_var.
766 * root.c (mark_root): Uses changed.
767 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
768 * init.c (scm_start_stack): Uses changed.
769 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
770 Change scheme-visible name to *top-level-lookup-closure* from
771 *top-level-lookup-thunk*.
773 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
775 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
776 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
778 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
780 * gc.c (struct scm_heap_seg_data): Doc fixes.
782 * gc.c (scm_gc_sweep): Empty all segments' freelists before
783 sweeping. Then, prepend each segment's free cells to its
784 freelist, rather than wiping out the old value. (Thanks to Marius
787 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
788 scm_check_freelist, scm_debug_newcell): New functions and
789 variables, for debugging freelist problems.
790 * pairs.h (SCM_NEWCELL): New debugging version added.
791 * gc.h (scm_debug_newcell): Added extern declaration, used by
792 debugging version of SCM_NEWCELL.
794 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
796 On some systems <libc.h> conflicts with <unistd.h>, and should not
798 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
799 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
800 * configure.in: Call it.
801 * posix.c, filesys.c: Use its results to decide whether or not to
803 * configure, scmconfig.h.in: Rebuilt with autoconf and
806 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
808 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
809 pointer to the stdio stream before calling scm_setbuf0, so the
810 latter will be able to retrieve it. I'm surprised this didn't
811 segfault earlier. (Thanks to Christopher Lee.)
813 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
815 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
818 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
820 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
821 number of stack narrowing specifier pairs. The first specifier in
822 a pair controls inner border, the second the outer border. A
823 number means cut that number of frames, a procedure object means
824 cut until that object is found in operator position in a frame.
826 * root.c (cwdr): Bugfix.
828 * read.c: Recording of positions disabled by default.
830 * procs.c (scm_closure_p): New function.
832 * posix.c (scm_tmpnam): New function.
834 * load.c: Added #include "throw.h".
835 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
838 * load.c, load.h (scm_read_and_eval_x): New function.
840 * eval.c: Renamed debug option "deval" to "debug".
842 (scm_eval_x): `eval!' is no longer accessible from the scheme
843 level. Motivation: We can't allow operations which introduce
844 glocs into the scheme level. Guile's type system can't handle
845 these as data. Use `eval' or `read-and-eval!' as replacement.
847 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
848 SCM_CONSP since this is a macro!; Set vframe.prev to
849 scm_last_debug_frame instead of 0. In this way we can look
850 "above" the virtual start stack frame if we wish.
851 (scm_debug_hang): New function: Useful for debugging Guile in
852 certain tricky situations. Will probably be removed later...
854 * debug.h: Changed semantics of debug option "backtrace". This
855 option now only indicates whether we want automatic backtrace at
858 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
860 * ports.c: #include "filesys.h"
861 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
863 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
864 Motivation: This is system specific code which is related to file
865 I/O. It also may use select. Added code by Gary Houston to
866 detect presence of character in stdio buffers.
868 * libguile.h: #include "libguile/libpath.h"
870 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
871 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
872 SCM_SITE_DIR; Install libpath.h among the other include files.
874 * load.c, load.h (scm_sys_package_data_dir): New function.
876 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
878 * stacks.h: Bugfix: Don't use tail-array length field as stack
879 length field! This screwed GC.
881 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
883 * _scm.h: Added #ifndef around definition of macros min and max.
885 * __scm.h: Added hooks for threads to plugin to in ints protection
886 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
887 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
888 the main code in these macros duplicated and spread over multiple
889 files. Renamed SCM_THREADS_SWITCHING_CODE ->
890 SCM_THREAD_SWITCHING_CODE.
892 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
895 * guile-snarf.sh: New file.
896 * Makefile.in (inner_h_files): Added snarf.h
897 (ancillary, install, uninstall, distclean): Added actions for
899 (.c.x): Use guile-snarf.
900 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
901 (gen_c_files): Note that these depend on guile-snarf.
902 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
903 now in "snarf.h". Added #include "snarf.h" to get them.
904 * libguile.h: Added #include "snarf.h".
905 (Patches applied and tweaked by Jim Blandy.)
907 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
909 * socket.c: Use K&R style declaration for 'close'; the GNU coding
910 standards suggest against providing prototypes for system
911 functions. Thanks to Greg Troxel.
913 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
915 * strports.c (scm_eval_0str): New function.
916 #include "read.h", to get prototype for scm_read.
917 * Makefile.in (strports.o): Update dependencies.
918 * strports.h: New prototype.
920 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
921 scheme name from "int?" to "integer?". It seems to do the job.
922 * numbers.h: Rename prototype too.
923 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
926 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
927 scm_num_eq_p): Rename these according to R4RS conventions: call
928 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
929 to making libguile R4RS compliant without ice-9...
931 * load.c (scm_sys_search_load_path): Search for files under all
932 extensions listed in the %load-extensions variable. If FILENAME
933 is absolute, return it unchanged, without searching the load path.
934 (scm_loc_load_extensions): New variable, pointing to
935 %load-extensions' value cell.
936 (scm_init_load): Initialize it, and the value it points to.
937 (scm_primitive_load_path): Improve error reporting.
939 * load.c (scm_loc_load_hook): New variable, pointing to value cell
940 of new Scheme variable %load-hook.
941 (scm_primitive_load): Apply %load-hook to filename.
943 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
945 * configure.in: add tests for figuring out whether buffered data
946 is available in a FILE structure, which is needed by char-ready.
948 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
951 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
952 exceptions using misc_error instead of syserror. It seems a bit
953 odd to throw an exception if a string can't be found in the
954 environment, but it's consistent with open-file, stat etc.
955 (simpos.h): remove sys_ from getenv.
957 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
958 occurs, throw an error instead of returning errno. Return value
960 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
962 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
964 * filesys.c (scm_stat2scm): derive file type and permissions from
965 the stat mode and append them to the returned vector.
966 There isn't much overhead in doing this and it avoids the need to
967 work with S_IRUSR et al. in Scheme.
968 Define symbols scm_sym_regular etc.
969 (scm_init_filesys): don't intern S_IRUSR etc.
971 * load.c: change s_try_load and s_try_load_path to s_primitive_load
972 and s_primitive_load_path.
974 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
976 * error.h: don't declare error symbols. prototype for scm_misc_error.
978 * stackchk.c (scm_stack_overflow_key): defined here instead of in
981 * error.c: use SCM_SYMBOL to set up error keys.
982 scm_misc_error: new procedure.
984 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
986 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
987 between `#!' and `!#' is ignored.
988 (skip_scsh_block_comment): New function.
990 * feature.c (scm_set_program_arguments): New argument, FIRST.
991 * feature.h: Update prototype.
992 * init.c (scm_boot_guile_1): Pass new argument to
993 scm_set_program_arguments.
995 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
997 * init.c (scm_start_stack): Don't initialize scm_progargs here.
998 (scm_boot_guile): Call scm_set_program_arguments here, later than
999 the old initialization.
1001 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1002 initialization procedure.
1003 - Delete in, out, err arguments; there are other perfectly good
1004 ways to override these when desired.
1005 - Delete result argument; this function shouldn't ever return.
1006 - Rename init_func argument to main_func, for less confusion.
1007 - Delete boot_cmd argument; main_func is more general.
1008 -Add 'closure' argument, to help people pass data to main_func
1009 without resorting to global variables.
1010 - Abort if reentered; don't bother returning an error code.
1011 - Call scm_init_standard_ports to set up the default/current
1012 standard ports; no need to pass them to scm_start_stack.
1013 - Remove code to evaluate the boot_cmd, and start the repl; let
1014 the user do something like that in main_func if they want.
1015 - Remove code to package up a return value; main_func can do any
1017 - Call exit (0), instead of returning.
1018 (scm_start_stack): Don't initialize the I/O ports here; that's
1019 weird. Delete in, out, err arguments. Move guts to
1020 scm_init_standard_ports, scm_stdio_to_port.
1021 (scm_init_standard_ports): New function, to set up current and
1022 default standard ports.
1023 (scm_start_stack, scm_restart_stack): Make these static.
1024 * init.h (scm_boot_guile): Adjust declaration.
1025 (scm_start_stack, scm_restart_stack): Remove externally
1026 visible declarations for these.
1027 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1029 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1030 written out several times in scm_start_stack.
1031 * fports.h: New declaration for the above.
1033 * feature.c (scm_set_program_arguments): New function.
1034 * feature.h: New declaration for the above.
1036 * ports.c: Formatting tweak.
1038 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1040 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1041 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1042 for obtaining the address of a car or cdr field. Motivation:
1043 &SCM_CXR make assumptions about the internal structure of the
1046 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1047 Motivation: see SCM_CXRLOC.
1049 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1050 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1051 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1052 Motivation: Safer use. Some other macros are defined in terms of
1053 these operations. If these are defined using the SCM_SETCXR
1054 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1055 to inefficiency and an <e1> with side-effects could potentially
1056 break. Also, these particular operations are heavily utilized in
1057 the garbage collector. In unoptimized code there will be a
1060 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1061 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
1062 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
1063 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
1064 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
1065 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1066 vports.c: Cleaned up use of pairs: Don't make any special
1067 assumptions about the internal structure of selectors and
1068 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1069 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1070 (Among other things, this change makes it easier to build Guile
1071 with certain compilers which have problems with casted lvalues.)
1073 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1075 * stacks.c: Improve selection of relevant stack frames when making
1076 a stack object. Introduce one level of indirection in the stack
1077 object to make it possible to "narrow" to a certain region of the
1078 stack. This facilitates making use of more clever algorithms (not
1079 implemented) for selecting relevant frames and gives a cleaner
1080 design since selection of frames can be done independently of
1081 extraction of frames from the real stack.
1082 (scm_stack_id): Also take #t as argument which means look at
1085 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1086 Turn n_tail into an integer directly representing current number
1087 of frames in stack. Add field tail.
1089 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1091 * debug.c (scm_make_memoized): Made it available at scheme level.
1092 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1093 SCM_NIMP before applying heavier predicates in argument checking.
1094 (scm_local_eval): Also take memoized object as argument.
1096 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1097 aren't created with zero length, but should such a strange
1098 creature suddenly turn up...
1100 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1102 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1103 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1105 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1107 * variable.c (scm_make_variable): Make the name hint optional, as
1109 (anonymous_variable_sym): Renamed from variable_sym. All uses
1112 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1113 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1114 of scm_primitive_load_path was also changed to
1115 "primitive-load-path", from "%try-load-path". Callers changed.
1116 We'd like to respect the convention that a function named
1117 "try-mumble" should behave just like the function called "mumble",
1118 but return #f instead of signalling some error.
1119 * load.h: Rename prototypes.
1121 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1123 * print.c (make_print_state, grow_print_state), print.h: Modified
1124 the print state representation: Don't use a tail array for
1125 recording of circular references. Resizing of the print state
1126 structure invalidates the print state pointer. To avoid passing
1127 around an indirect print state reference to all printing
1128 functions, we instead let the print state reference a resizable
1131 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1133 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1134 Don't crash when passed an improper list terminated by a
1135 non-immediate value.
1137 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1139 Allocate data for structures on an eight-byte boundary, as
1140 required by the tagging system.
1141 * struct.c (alloc_struct): New function.
1142 (scm_make_struct, scm_make_vtable_vtable): Call it.
1143 * struct.h (scm_struct_n_extra_words): Bump to 3.
1144 (scm_struct_i_ptr): New "field".
1145 * gc.c (scm_gc_sweep): When we need to free the data, use the
1146 information stored by alloc_struct to find the beginning of the
1147 block allocated to the structure, so we can free it.
1149 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1151 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1154 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1155 (scm_debug_info): New member: id.
1157 * stacks.c: Stacks are now represented as structs; Stacks have an
1158 id given to them by `start-stack'.
1159 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1161 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1162 Changed stack representation.
1164 * debug.c (scm_procedure_name): Try procedure property `name' for
1165 compiled closures aswell.
1167 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
1169 * eval.c: scm_i_name moved to gsubr.c
1170 (scm_m_define): Record names of all kinds of procedure
1171 objects. (Earlier, only closures were recorded.)
1173 * procprop.h: Added declaration of scm_i_name.
1175 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1176 (scm_make_gsubr): Record names of compiled closures.
1178 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1180 * debug.c, debug.h: Removed obsolete code.
1182 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1183 stacks.c: Renamed regs --> scm_contregs.
1185 * print.c (scm_free_print_state): Cleanup print state before
1186 returning it to pool. It is better to do it here than in
1187 scm_prin1 since scm_prin1 is called often.
1189 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1190 s_set_source_property_x): Check that first argument is a pair or a
1193 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1194 scm_i_line, scm_i_column and scm_i_breakpoint global.
1196 * init.c: Added #include "backtrace.h" and #include "stacks.h".
1197 (scm_boot_guile_1): Added calls to scm_init_backtrace and
1200 * debug.h: Added debug object smob declaration and macro
1203 * configure.in: Build with backtrace.o and stacks.o if debug
1206 * Makefile.in: Added entries for new files: backtrace.c,
1207 backtrace.h, stacks.c and stacks.h.
1209 * symbols.c (scm_sym2ovcell): Fixed documentation.
1211 * _scm.h (min, max): Added.
1213 * async.c: Moved `min' macro to _scm.h.
1215 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1216 SCM_BACKTRACE_INDENT.
1218 * eval.c: Added new debug options `maxdepth' and `indent'.
1220 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
1222 * print.h: Added selector SCM_PRINT_STATE.
1224 * print.c: New functions: scm_make_print_state,
1225 scm_free_print_state.
1227 * print.h: Added declarations for scm_make_print_state,
1228 scm_free_print_state.
1230 * debug.c (scm_m_start_stack): New acro.
1232 * debug.h: Small cleanup.
1234 * init.c (scm_boot_guile_1): Moved scm_init_debug below

1262 More prototype-related changes from Marius Vollmer:
1263 * gdb_interface.h: Wrapped header file in #ifdef/#endif
1264 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
1265 * ports.h (ptobfuns): Added prototypes. This means some casting in
1267 * fports.c: Added casts for initializations, since the functions
1268 are defined to take FILE * as their stream argument, not SCM.
1269 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
1270 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
1271 to `char *str_data' to conform to prototype.
1273 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1275 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
1277 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
1279 * stime.c, stime.h: use SCM_P method.
1281 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1283 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
1284 be given at least two arguments. Insist that lst's last element
1285 be a list, but don't make any requirements of its predecessors.
1287 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1289 * eval.c (scm_nconc2last): Revert last change; there seems to be
1290 other stuff going on here.
1292 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1294 * eval.c (scm_nconc2last): Make sure that each element of lst
1295 (which is a list of argument lists, except for the tail) is a
1296 proper list, i.e., finite and terminated by '().
1298 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1300 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
1303 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
1304 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
1307 * vectors.c (scm_make_vector): Fill vectors with the undefined
1308 value, to help make Guile Scheme code more portable to other
1311 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
1312 * symbols.h, tags.h: Doc fixes.
1314 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>

1318 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
1320 * numbers.c (scm_divbigint): When the remainder is zero, we don't
1321 want to subtract it from the modulus; we just want to leave it
1324 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
1326 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
1329 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
1331 * throw.c (scm_catch_apply): Finished implementation of
1334 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
1336 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
1338 (scm_init_filesys): set "i/o-extensions" feature.
1341 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
1343 * Makefile.in (root.o): Correct dependencies.
1345 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
1347 * Makefile.in: Added dependency entry for root.o.
1349 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
1350 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
1352 * init.c (scm_start_stack): Set initial root continuation number
1355 * procs.c: New function: scm_thunk_p.
1357 * procs.h: Added declarations of scm_thunk_p.
1359 * root.c: Renamed `call-with-new-root' -->
1360 `call-with-dynamic-root'.
1361 (cwdr): Removed allocation of new root state. This should be done
1362 separately by use of scm_make_root.
1363 (scm_apply_with_dynamic_root): New function: Does what it
1364 sounds like. Needed when spawning threads.
1366 * root.h: Added member last_debug_frame to root state.
1367 Added #include "libguile/debug.h"
1369 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
1370 arguments. The motivation is that code in root.c needs catch
1371 functionality, and we want to avoid code duplication.
1372 New functions: scm_catch, scm_lazy_catch. These are wrappers for
1373 scm_catch_apply. scm_lazy_catch is intended to introduce catch
1374 handlers that run without popping the stack into the dynwind
1377 * throw.h: Added prototypes for scm_catch_apply and
1380 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1382 * root.h (scm_root, scm_set_root): Decouple thread support details
1383 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
1384 SCM_SET_THREAD_LOCAL_DATA.
1386 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
1387 and tortoise scanning loop.
1389 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
1391 * Makefile.in: Rebuild dependencies.
1393 * libguile.h: #include "libguile/print.h" before "smob.h", since
1394 the latter uses the print_state structure.
1396 * throw.c (scm_ithrow): Use the correct variable when checking to
1397 see if a given element of scm_dynwinds is a valid catch.
1399 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
1400 structure, abort; don't just silently ignore the garbage.
1402 * _scm.h: #include "print.h" here, since it seems to be used just
1404 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
1405 strports.c, unif.h: Don't #include "print.h".
1407 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1409 * feature.h (scm_loc_features): Removed external declaration.
1410 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
1412 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1414 * feature.c (scm_init_feature): Added threads feature (needs to be
1415 initialized here, since features doesn't exist when
1416 scm_init_threads is called).
1418 * libguile.h: Added #include "libguile/../threads/threads.h".
1419 (This is a kludge to get thread support working. This should be
1422 * configure.in, acconfig.h: Added flags for thread support.
1424 * scmsigs.c: Define `signal' to be `pthread_signal' if using
1427 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
1428 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
1431 * _scm.h: Added conditional #include "threads.h"
1433 * __scm.h (SCM_ASYNC_TICK): Added call to macro
1434 SCM_THREADS_SWITCHING_CODE.
1436 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
1437 allocate the basic dynamic root object.
1438 (scm_boot_guile): Added call to scm_init_root.
1440 * root.c, root.h: Added root smob.
1441 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
1442 functions: Implements dynamic roots mostly according to spec in
1443 SCM manual. Main difference is that the second argument is a
1444 throw handler rather than an error "thunk".
1446 * root.h: Added declaration of scm_init_root.
1448 * root.c: Added #include "genio.h", #include "smob.h", #include
1449 "pairs.h", #include "throw.h", #include "dynwind.h", #include
1451 (scm_init_root): Added #include "root.x".
1453 * throw.c: Added #include "stackchk.h"
1454 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
1455 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
1456 can be used in scm_call_with_new_root; Added reenabling of stack
1457 checking when catching a throw.
1459 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
1461 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
1463 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
1464 element is not found, as per R4RS.
1466 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1468 * list.c: Doc fixes throughout.
1470 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1472 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
1473 declare the char * to be const. Avoids a warning in rgx.c.
1475 * ports.h: spelling fix.
1477 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
1480 * load.c (scm_sys_try_load_path): throw an error if file not found
1481 (like it says it in NEWS).
1483 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1485 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
1486 PROPS slot to '(), not #f; it's an empty alist.
1488 * throw.h, throw.c: Use SCM_P instead of #if hair.
1490 Remove special support for uncaught throws; see throw.c for
1492 * throw.c (uncaught_throw): New function.
1493 (scm_ithrow): Call uncaught_throw if we don't find a throw
1494 target; don't mess with scm_bad_throw_vcell.
1495 (scm_bad_throw_vcell): Variable deleted.
1496 (scm_init_throw): Don't initialize it.
1498 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
1501 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1503 * numbers.c (scm_istr2int): If the number is short (as most
1504 numbers are), just call scm_small_istr2int to deal with it.
1505 (scm_small_istr2int): New function, created by un-#ifdefing the
1506 non-bignum version of scm_istr2int and renaming it.
1508 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
1510 * load.c (scm_sys_try_load): don't check whether value returned
1511 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
1512 Change the Scheme name from %try-load to primitive-load.
1514 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
1515 Can avoid passing a message, allowing it to be derived in the
1516 error handler (e.g., if we want to throw to the key both from
1519 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
1521 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
1522 references now have a new appearance which is more compact and
1523 also gives a clue about what the target of the reference is.
1524 By setting parameters in the print state, more fancy printing can
1525 be achieved. This is used by the (not yet commited) backtrace
1528 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
1530 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
1533 * print.c: Added #include "struct.h". Removed function
1536 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
1537 scm_iprin1. Removed prototype for scm_prlist.
1539 * arbiters.c (prinarb),
1540 async.c (print_async),
1541 debug.c (prindebugobj, prinmemoized),
1542 eval.c (prinprom, prinmacro),
1543 filesys.c (scm_fd_print, scm_dir_print),
1545 mallocs.c (prinmalloc),
1546 numbers.c, numbers.h (scm_floprint, scm_bigprint),
1547 smob.h (scm_smobfuns),
1548 srcprop.c (prinsrcprops),
1550 unif.c, unif.h (scm_raprin1, rapr1),
1551 variable.c (prin_var): Changed argument `int writing' to
1552 `scm_print_state *pstate'.
1554 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
1555 that it will be called before scm_init_print.
1557 * print.c (scm_prin1): Print states are now allocated when calling
1558 scm_prin1 and then passed around to all printing functions as an
1559 argument. A cache `print_state_pool' enables reuse of print
1561 (scm_make_print_state): New function.
1562 (scm_iprin1): Adaption to print states.
1563 (scm_iprlist): An initial "hare and tortoise" scan brings down
1564 time complexity to O (depth * N). (Better time complexity will be
1565 achieved when the printing code is completely rewritten.)
1567 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1569 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
1570 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
1571 it gets done whether or not the cache variable has a value.
1573 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
1575 Distinguish #f and ().
1576 * __scm.h: #undef SICP.
1577 * pairs.h (SCM_EOL): Delete this definition, equating it with
1579 * tags.h (SCM_EOL): Give it a new definition here; I think I found
1580 the value it used to have. Doc fixes, too.
1582 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
1584 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
1585 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
1586 Lord's implementation of structs, allowing for tail arrays as
1587 described in the manual. Also fixed some bugs. (Both the interface
1588 and the implementation should be improved.)
1590 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
1592 * print.c, print.h: Closures now print like #<procedure foo (x)>.
1593 People who whish to see the source can do `(print-enable 'source)'.
1594 Removed #ifdef DEBUG_EXTENSIONS.
1596 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1598 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
1599 integer (assuming for now accepting an integer is a good thing).
1601 * error.c, fports.c: replace use of %S in lgh_error args with %s.
1602 %S will be used instead for write'ing arguments.
1604 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
1605 asserts. fix a few other asserts.
1606 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
1607 scm_uniform_vector_ref, scm_array_set_x,
1608 scm_dimensions_to_unform_array): change args in
1609 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
1610 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
1611 scm_substring_fill_x): likewise.
1612 gsubr.c (scm_gsubr_apply): likewise.
1613 eval.c (SCM_APPLY): likewise.
1615 * eval.c (4 places): replace scm_everr with lgh_error or
1618 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
1619 scm_memory_error): new procedures.
1620 scm_everr: deleted. can use scm_wta, dropping first two args.
1621 scm_error: convert NULL subr to SCM_BOOL_F.
1623 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
1626 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
1629 * error.c, error.h: new error keys: scm_arg_type_key,
1630 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
1632 scm_wta: reimplement using lgh_error instead of scm_everr.
1634 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
1636 * gdbint.c: scm_lread now has one more argument.
1638 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
1639 scm_port_\1; Added mutator scm_set_port_filename_x (used when
1640 loading source from non-file ports, which, e. g., happens when
1641 using the Emacs interface).
1643 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
1646 * read.c: Added code for recording of positions of source code
1647 expressions; New functions: recsexpr, scm_lreadrecparen;
1648 _scm_make_srcprops --> scm_make_srcprops
1649 (scm_flush_ws): Removed updating of positions counters. This work
1650 is already done by scm_gen_getc
1652 * read.h: Added prototype for scm_lreadrecparen
1654 * print.c: Added #include "alist.h"
1656 * eval.c: Added #include "hash.h"
1658 * eq.c: Added #include "ramap.h"
1660 * options.c: Documentation fixes.
1662 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
1663 (scm_init_srcprop): Adjusted size of initial source-whash. Name
1664 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
1665 --> scm_make_srcprops
1667 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
1668 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
1669 function calls in the definition of the whash access macros.
1671 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
1673 * init.c (scm_boot_guile): Add level of indirection to
1674 scm_boot_guile_1() to ensure that stack base pointer is properly
1675 initialized. There was no guarantee that variable i was the
1676 highest/lowest variable on stack (i.e. the call frame of
1677 scm_boot_guile was not completely protected from gc).
1679 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
1681 * ports.h (scm_port_table): put back file_name, it will be used to
1682 support debugging. Undo related changes in fports.c, ioext.c,
1685 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1687 * ports.h (scm_port_table): remove file_name member for now, it seems
1689 * fports.c (scm_open_file): don't set file_name in PTAB.
1690 (prinfport): don't use file_name in PTAB.
1691 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
1692 * ports.c (scm_add_to_port_table): don't intialize file_name.
1693 (scm_port_file_name): remove for now.
1694 * gc.c (scm_gc_mark): don't mark PTAB file_name.
1696 * fports.h (scm_mkfile): prototype deleted.
1697 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
1699 * debug.c, unif.c: use scm_out_of_range instead of
1700 wta for range errors (ASSERT still needs work).
1702 * error.c, error.h (scm_out_of_range): new procedure.
1704 * error.c, error.h (scm_out_of_range_key): new key.
1706 * posix.c (scm_sync): #else was missing.
1708 * error.c, error.h: append _key to names scm_num_overflow and
1711 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
1712 of consing an empty list.
1713 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
1714 of macros, saves code and string space.
1715 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
1716 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
1717 lower case. Rename scm_syserror_m to scm_syserror_msg.
1718 error.h: prototypes for new procedures.
1720 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
1722 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
1724 * error.c, error.h: setup scm_num_overflow key.
1726 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
1727 Remove definition of SCM_OVSCM_FLOW.
1729 * fports.c (scm_open_file): use SCM_SYSERROR_M.
1731 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
1732 explicit message and args.
1734 * error.c, error.h, __scm.h: change system_error_sym to
1737 * error.c (system_error_sym): remove leading %% from the Scheme name
1740 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
1742 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1744 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
1745 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
1746 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
1747 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
1748 renamed. (These were introduced by unsupervised name
1751 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1753 * print.c: Added code for detection of circular references during
1754 printing. (init_ref_stack, grow_ref_stack): New functions. Added
1755 a hook for printing of closures (accessible via print options).
1756 This leads to a split of calls to scm_iprin1 into two classes:
1757 elementary print operations (e. g. the code which prints a smob)
1758 still use scm_iprin1 while top level calls (like scm_display) use
1759 scm_prin1. scm_prin1 begins by clearing the data structure used
1760 to record reference information.
1762 * print.h: Added declarations of scm_prin1 and scm_prlist.
1764 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
1766 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
1768 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
1770 * error.c (err_head): scm_iprin1 --> scm_prin1
1772 * debug.c: Adjusted header comment.
1776 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1778 * strerror.c: Doc fix.
1780 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1782 * gdbint.c (gdb_read): Now possible to run during GC.
1783 (unmark_port, remark_port): New functions.
1785 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
1787 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
1788 of allocating a new string object. Also, increase size by
1789 the factor 2 instead of 1.5.
1791 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
1793 * __scm.h (SCM_P): Corrected to run under traditional C.
1795 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
1798 * async.c: Calls to scm_sysintern corrected.
1800 * async.h (scm_async_clock): Redundant declaration removed.
1802 * continuations.c (scm_dynthrow): Redundant declaration removed.
1804 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
1805 Definition typos corrected.
1807 * debug.h: Missing declarations of functions in debug.c added
1810 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
1811 Missing declarations to functions in eval.c added.
1813 * filesys.c: Possibly uninitialized variable rv.
1815 * gc.h (scm_object_addr, scm_unhash_name): Missing
1816 declarations of functions defined in gc.c added.
1818 * genio.c: Possible typos str_data -> wstr_data. ???
1820 * genio.c: Possibly unintended shadowing of local variable
1821 `int c' (gotos out of scope of inner `c'). ???
1823 * init.c: Uninitialized `SCM last' may be used.
1825 * ioext.h: (scm_sys_isatty_p): Typo.
1827 * list.h (scm_list_head): Missing prototype for function in
1830 * numbers.c (scm_two_doubles): Changed from extern to static
1831 (is used only within numbers.c).
1833 * numbers.h: Repeated declarations removed.
1835 * ports.h (scm_close_all_ports_except): Declaration for the
1836 function defined in ports.c added.
1838 * posix.h: Missing declarations added.
1840 * procs.h (scm_make_subr_opt): Missing declaration added.
1842 * socket.h (scm_sys_gethost): Missing declaration added.
1844 * socket.h: Redundant declarations removed (they are in fdsocket.h).
1846 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
1847 Missing declarations added.
1849 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
1851 * struct.c: Uninitialized variable `SCM answer' may be used.
1853 * unif.c (l2ra): Declaration prototype.
1855 * unif.c (scm_array_equal_p): Dummy definition removed (it is
1856 defined in ramap.c).
1858 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
1859 Redundant declarations removed (they are in ramap.h).
1861 * variable.h (scm_make_udvariable,
1862 scm_make_undefined_variable): Declaration corrected to
1863 correspond variable.c.
1865 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
1866 Missing declarations added.
1868 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
1870 * Makefile.in (distclean): Don't forget to delete fd.h.
1872 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1874 * fd.h.in, tags.h: Trivial cleanups.
1876 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
1877 marksweep.h just declared functions from gc.c.
1878 * gc.h, libguile.h: Don't #include "marksweep.h".
1879 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
1880 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
1881 dependencies updated.
1883 * libguile.h: Don't #include "files.h"; it's been deleted.
1885 * files.c (scm_sys_delete_file): Moved to filesys.c.
1886 File is now empty; deleted.
1888 * filesys.c: scm_sys_delete_file is now here. Remove
1889 #if's; they seem to rely on remnants of an old portability
1890 regimen. If the problems come up again, solve them properly,
1891 using autoconf. Specifically: Don't test M_SYSV, and #define
1892 remove to be unlink if it's #defined; don't use remove just
1893 because HAVE_STDC_HEADERS is #defined.
1894 * filesys.h: Add declarations for scm_sys_delete_file.
1895 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
1896 files.o, files.h, files.c, and files.x.
1897 * init.c: Don't #include "files.h", and don't call scm_init_files.
1899 Use SCM_P instead of PROTO; the latter intrudes on the user's
1901 * params.h: Deleted; definition of SCM_P moved to...
1902 * __scm.h: ... here, where it replaces PROTO macro.
1903 * libguile.h, smob.h: Don't #include "params.h".
1904 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
1905 smob.h: Fix prototypes accordingly.
1906 * Makefile.in: Update dependencies.
1907 (inner_h_files): Remove params.h.
1909 * gc.c: #include "gc.h"; every module should include its header,
1910 to let the compiler cross-check the declarations against the
1913 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
1914 simpos.h: #include "libguile/__scm.h".
1916 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
1918 * init.c: Don't forget to #include smob.h and init.h.
1919 * Makefile.in: Dependencies updated.
1921 * smob.h: Use PROTO instead of #if __STDC__.
1923 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
1925 * __scm.h: Doc fixes.
1927 * __scm.h, libguile.h: Use "quotes" in the #includes, not
1928 <angles>; this allows `make depends' to work properly.
1930 * libguile.h: #include smob.h and pairs.h before the others; they
1931 define typedefs used by other headers.
1933 C files should #include only the header files they need, not
1934 libguile.h (which #includes all the header files); the pointless
1935 recompilation was wasting my time.
1936 * Makefile.in (all .o dependency lists): Regenerated.
1937 * libguile.h: Don't try to get a definition for size_t here...
1938 * __scm.h: Do it here.
1939 * _scm.h: Since this is the internal libguile header, put things
1940 here that all (or a majority) of the libguile files will want.
1941 Don't #include <libguile.h> here; that generates dependencies on
1942 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
1943 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
1944 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and
1946 * alist.c: Get "eq.h", "list.h", "alist.h".
1947 * append.c: Get "append.h", "list.h".
1948 * arbiters.c: Get "arbiters.h", "smob.h".
1949 * async.c: Get "async.h", "smob.h", "throw.h", "eval.h".
1950 * boolean.c: Get "boolean.h".
1951 * chars.c: Get "chars.h".
1952 * continuations.c: Get "continuations.h", "dynwind.h", "debug.h",
1954 * debug.c: Get "debug.h", "feature.h", "read.h", "strports.h",
1955 "continuations.h", "alist.h", "srcprop.h", "procprop.h", "smob.h",
1956 "genio.h", "throw.h", "eval.h".
1957 * dynwind.c: Get "dynwind.h", "alist.h", "eval.h".
1958 * eq.c: Get "eq.h", "unif.h", "smob.h", "strorder.h",
1960 * error.c: Get "error.h", "throw.h", "genio.h", "pairs.h".
1961 * eval.c: Get "eval.h", "stackchk.h", "srcprop.h", "debug.h",

2043 * stackchk.h: #include "libguile/debug.h",
2045 * print.h, read.h: #include "options.h", since everyone who uses
2046 either of these files will need that.
2048 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2049 anyone who uses this file will need them to define the smob
2050 printing functions. Also, get markers.h, since people will need
2051 to #define the mark functions.
2053 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2054 * ports.h: ... to here.
2056 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2057 don't rely on archaic C default type rules.
2059 * fports.h: #include "libguile/ports.h", since you need that in
2060 order to parse this.
2062 * genio.h: #include "libguile/print.h", because you need that to
2063 parse this; don't bother #including "ports.h", since print.h gets
2066 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2068 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2069 this; it's now a reference to an element of *scm_root.
2071 * debug.h: Don't #include "options.h"; the compiler won't be able
2072 to find that once the headers are installed; instead, #include
2073 "libguile/options.h".
2074 * gc.h: Same, with marksweep.h.
2075 * mbstrings.h: Same, with symbols.h.
2076 * scmhob.h: Same, with _scm.h.
2077 * smob.h: Same, with params.h.
2079 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2080 C files; there's no need for this, and it forces recompilations
2083 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2085 * error.c (scm_error): declare scm_error_callback.
2087 * error.h: prototype for scm_error_callback.
2089 * __scm.h: define lgh_error.
2090 (SCM_SYSERROR): redefine using lgh_error.
2092 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2094 * error.c (scm_error): new procedure.
2096 * error.h: prototype for scm_error.
2098 * Makefile.in (install): install scmconfig.h from the current
2099 directory, not $(srcdir).
2101 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2103 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2104 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2105 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
2106 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
2107 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
2108 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2109 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2110 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2111 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2112 vports.h, weaks.h: #include "libguile/__scm.h", not
2113 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2114 dependencies are within libguile properly.
2116 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2118 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2119 when scmconfig.h doesn't exist.
2121 * load.c (scm_sys_try_load): Correct spelling.
2123 * feature.c (scm_loc_features): Make this static.
2125 * Makefile.in (libpath.h): Omit trailing slash from path. We
2126 shouldn't require it of users, so why put it here?
2128 Move code to initialize and search %load-path from ice-9 to C
2129 code, so we can use the load-path to find the ice-9 boot code;
2130 this makes it easier to run Guile without installing it. See
2131 corresponding changes in guile/Makefile.in.
2132 * feature.c: Move stuff concerned with the load path to load.c.
2133 (scm_compiled_library_path): Deleted.
2134 Don't #include libpath.h here.
2135 * feature.h: Don't mention scm_compiled_library_path.
2136 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2137 <sys/stat.h>, and <unistd.h> (if present).
2138 (R_OK): #define if the system hasn't deigned to.
2139 (scm_loc_load_path): New variable.
2140 (scm_init_load_path, scm_sys_search_load_path,
2141 scm_sys_try_load_path): New functions.
2142 (scm_init_load): Initialize scm_loc_load_path to point to the
2143 value cell of the Scheme %load-path variable.
2144 * load.h: Add declarations for scm_sys_search_load_path,
2145 scm_sys_try_load_path.
2146 * init.c: Call scm_init_load_path.
2147 * Makefile.in (feature.o, load.o): Dependencies updated.
2149 * load.c, load.h: Rewrite using PROTO macro.
2151 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2153 * gc.c (scm_cellp): New function: C predicate to determine if an
2154 SCM value can be regarded as a pointer to a cell on the heap.
2156 * gc.h: Added declaration of scm_cellp.
2158 * gdb_interface.h: New file: The GDB interface header from the GDB
2161 * gdbint.c: New file: GDB interface.
2163 * gdbint.h: New file: GDB interface.
2165 * libguile.h: Added #include <libguile/gdbint.h>.
2167 * init.c (scm_boot_guile): Added scm_init_gdbint.
2169 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2170 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2171 found if object files and source are kept separate).
2173 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2175 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2177 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2179 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2180 TK_SRC_DIR; they're not relevant any more.
2182 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2183 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2185 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2187 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2188 search path, so we can find the <libguile/MUMBLE.h> headers.
2190 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2192 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2193 implicit in the .c.o rule.
2194 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2197 Put the library path in a header file, instead of passing it on
2198 the command line in every compilation.
2199 * Makefile.in (libpath.h): New target.
2200 (feature.o): Depend on libpath.h.
2201 (clean): Delete libpath.h.
2202 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2203 * feature.c: ... #include "libpath.h" here.
2204 * .cvsignore: Ignore libpath.h.
2206 Don't install the unwashed masses of Guile header files in the
2207 main #include path; put most of them in a subdirectory called
2208 'libguile'. This avoids naming conflicts between Guile header
2209 files and system header files (of which there were a few).
2210 * Makefile.in (pkgincludedir): Deleted.
2211 (innerincludedir): New variable; this and $(includedir) are enough.
2212 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
2213 (installed_h_files): Divide this up. Now this variable lists
2214 those header files which should go into $(includedir) (i.e. appear
2215 directly in the #include path), and ...
2216 (inner_h_files): ... this new variable says which files appear in
2217 a subdirectory, and are referred to as <libguile/mumble.h>.
2218 (h_files): List them both.
2219 (install): Create innerincludedir, not pkgincludedir. Put
2220 the installed_h_files and inner_h_files in their proper places.
2221 (uninstall): Corresponding changes.
2222 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2223 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2224 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
2225 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
2226 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
2227 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2228 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2229 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2230 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2231 vports.h, weaks.h: Find __scm.h in its new location.
2232 * __scm.h: Find scmconfig.h and tags.h in their new locations
2233 (they're both "inner" files).
2235 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
2237 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
2239 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2241 * posix.c: Doc fixes.
2243 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
2245 * socket.c: Don't include a prototype for inet_aton; just use a
2246 K&R style declaration, to avoid warnings but minimize the chance
2247 of conflicts with the system.
2249 On NextStep, <utime.h> doesn't define struct utime, unless we
2250 #define _POSIX_SOURCE before #including it.
2251 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
2252 * acconfig.h: New comment text for above CPP symbol.
2253 * configure.in: Call it.
2254 * posix.c: #define _POSIX_SOURCE if it seems necessary.
2256 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
2258 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
2259 testing for __EMX__.
2261 * posix.c: #include <libc.h>, if it exists.
2263 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
2264 don't even know if the latter exists.
2266 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
2267 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
2268 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
2270 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
2272 (scm_init_posix): Use them when initializing the Scheme constants
2275 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2277 * Makefile.in (libdir, includedir, bindir): Use the
2278 autoconf-supplied values, instead of deriving them ourselves.
2279 (pkgincludedir, datadir, pkgdatadir): New variables.
2280 (install, uninstall): Put the header files in a special
2281 subdirectory, not in the main search path.
2283 * Makefile.in (ALL_CFLAGS): Provide the proper value for
2284 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
2286 * Makefile.in (IMPLPATH): Deleted; never used.
2288 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
2289 on the Tcl/Tk source any more.
2290 (INCLUDE_CFLAGS): Remove references to the above.
2292 * Makefile.in (version.o): Corrected dependencies.
2294 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
2296 * libguile.h: #include "version.h"
2298 * init.c (scm_boot_guile): Call scm_init_version.
2299 * gscm.c (gscm_run_scm): Call scm_init_version.
2301 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
2302 GUILE_VERSION): AC_DEFINE these.
2303 (acconfig.h): #undef the above symbols.
2305 * Makefile.in (libobjs): Add version.o.
2306 (installed_h_files): Add version.h.
2307 (c_files): Add version.c.
2308 (gen_c_files): Add version.x.
2309 (version.o): New rule.
2310 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
2311 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

2319 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
2320 weaks.o): Add version.h to dependency lists.
2321 (markers.o): Remove duplicate rule.
2323 * version.h: New file.
2325 * version.c: New file.
2327 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2329 * symbols.c (scm_strhash): scm_downcase is now a function, not an
2330 array; use it appropriately. Since GCC is quite happy to
2331 subscript functions, it never warned us about this; we should use
2332 -Wpointer-arith in the future. I guess we never tested
2335 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2337 * socket.c: Doc and copyright fixes.
2339 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2341 * debug.c: Fixed and improved gdb support.
2343 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2345 * socket.c: Added declaration of inet_aton to avoid compiler
2346 warning. (Hope this solution is correct.)
2348 * stime.c: Added declaration of ftime. (This is missing in
2351 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
2353 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2355 * Makefile.in (c_files): add strerror.c.
2357 * strerror.c: new file from Emacs' sysdep.c.
2358 maybe configure should also check for sys_errlist.
2360 * configure.in (AC_REPLACE_FUNCS): add strerror.
2362 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2364 * debug.c (scm_init_debug): Added initialization for
2365 scm_evaluator_traps.
2367 * debug.h, debug.c: Various name changes.
2368 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
2369 "debug-options-interface". See commentary in options.c.
2371 * options.h, options.c: Options now have documentation strings.
2372 Also added a long explanatory commentary.
2374 * eval.c, print.h, print.c, read.h, read.c: Modifications to
2377 * gscm.c, init.c, root.c, throw.c: Bug fixes:
2378 last_debug_info_frame is now updated in all cases.
2380 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
2383 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2385 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
2386 Added option STACK_CHECKING.
2388 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
2390 * Makefile.in: Added {debug,options,srcprop}.{h,c}
2392 * __scm.h: Removed symbols for debugging support.
2394 * acconfig.h: Added symbols for debugging support.
2396 * configure.in: Added user option for debugging support.
2397 --enable-debug will include the debugging code into libguile.a.
2399 * continuations.c (scm_make_cont): Enlarged the #if 0 around
2400 scm_relocate_chunk_to_heap.
2402 * debug.c: New file: low-level debugging support. It also
2403 includes support for debugging with gdb. (The extensions to gdb
2404 are written by Per Bothner at Cygnus.)
2406 * debug.h: New file: low-level debugging support.
2408 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
2409 argument pairs. Extensive modifications to the debugging
2410 evaluator. Added "SECTION:" commentaries to clarify what happens
2411 when, during double compilation. Renamed EVALIMP --> EVALIM.
2412 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
2413 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
2414 the beginning of the file. New procedure: scm_unmemocopy.
2415 Added some global state variables needed by the debugging
2416 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
2417 check_entry, check_apply, check_exit, debug_options and
2418 evaluator_traps. New acro: undefine.
2420 * eval.h: Renamed EVAL --> XEVAL.
2422 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
2423 --> scm_make_weak_key_hash_table.
2425 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
2426 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
2428 * libguile.h: Conditionally include debug.h
2430 * objprop.c (scm_object_properties, scm_set_object_properties_x):
2431 scm_object_properties shouldn't return handle. `handle' now gets
2432 initialized in scm_set_object_properties_x. scm_object_properties
2433 doesn't any longer create an entry in scm_object_whash.
2435 * options.c: New file: handling of run time options.
2437 * options.h: New file: handling of run time options.
2439 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
2441 * print.c: New procedure: scm_print_options
2443 * print.h: Defines for print options.
2445 * read.c: New procedure: scm_read_options
2447 * read.h: Defines for reader options.
2449 * root.h: Added scm_source_whash among scm_sys_protects.
2451 * srcprop.c: New file: source properties.
2453 * srcprop.h: New file: source properties.
2455 * throw.c (jbsmob): Jump buffers are now correctly allocated.
2456 (Bug found by A. Green.)
2458 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2460 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2462 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
2464 * libguile.h: #include "objprop.h"; I guess this was forgotten.
2466 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
2467 and should be called by the final client.
2469 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
2471 * gc.h: Use the PROTO macro when declaring functions.
2472 * gc.c: Use the PROTO macro when declaring static functions.
2473 Remove the CPP hair around function definitions.
2475 * gc.c (scm_init_storage): Initialize scm_asyncs.
2477 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
2478 preprocessor symbol; "__scm.h" is where it might get #defined.
2479 * __scm.h: Similar: #include <scmconfig.h> before testing
2482 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
2484 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
2486 * init.c (scm_boot_guile): Add init_func argument; call
2487 (*init_func) instead of calling scm_appinit; it's ucky to
2488 hard-code names for the user's procedures.
2489 * init.h (scm_boot_guile): Adjust declaration.
2491 * __scm.h (PROTO): New macro, for declaring functions with
2494 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
2495 eliminate all the __STDC__ conditionals.
2496 (scm_boot_guile): Add declaration.
2497 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
2498 Remove __STDC__ conditionals around function definitions; the
2499 declarations in init.h will provide the same information, more
2502 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
2503 complain about it in the error message; the error message is
2504 adequate without that note, and there's nothing the user can do
2507 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
2509 * Makefile.in (ancillary): Drop def.sed.
2511 * posix.c (scm_init_posix): Use numeric values, rather than
2512 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
2513 F_OK. The symbols aren't available on some systems, and I'm
2514 pretty sure their values are fixed by common widespread practice.
2515 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
2517 More functions unavailable on some systems.
2518 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
2519 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
2521 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2522 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
2523 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
2524 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
2525 stub that signals an error as the #else.
2527 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
2529 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
2531 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
2533 * unif.c: include ramap.h.
2535 * read.c (endif): case_insensative_p renamed case_insensitive_p.
2537 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
2539 * ports.c: include sys/ioctl.h.
2541 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
2543 * configure.in: check for sys/ioctl.h.
2545 * ports.c: include <malloc.h> not "malloc.h".
2547 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2549 * fports.c: remove ttyname and tmpnam declarations.
2551 * posix.c: fewer ttyname declarations.
2553 * fports.c: include <string.h> not "string.h".
2555 * init.c, ioext.c: include string.h and unistd.h.
2557 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2559 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
2560 genio.c, simpos.c, vports.c: include string.h.
2562 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
2564 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
2566 (scm_addr_buffer_size): change type from scm_sizet to int.
2567 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
2568 from scm_sizet to int.
2570 * error.c: include unistd.h.
2572 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
2575 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
2577 * __scm.hd, def.sed: deleted.
2579 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
2581 Changes for NeXT, suggested by Robert Brown.
2582 * configure.in: Call AC_TYPE_MODE_T.
2583 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
2584 NeXT. Put header file list in alphabetical order.
2585 * configure, scmconfig.h.in: Regenerated.
2586 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
2588 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
2591 * acconfig.h: New file, providing documentation for the CPP
2592 symbols defined in configure.in
2593 * acconfig-1.5.h: Removed; superceded by the above.
2595 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
2597 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
2599 * fports.c (scm_open_file): don't return #f, throw error.
2601 * ioext.c (fileno): renamed from %fileno.
2602 (soft-fileno): deleted.
2604 * ports.c (scm_port_revealed): don't need to check for -1 from
2606 (scm_set_port_revealed_x): return unspecified, not #f.
2608 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
2610 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
2612 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
2614 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
2616 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2618 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
2619 This is necessary on Ultrix, and doesn't hurt portability.
2621 * Makefile.in (dist-dir): New target, implementing a new dist system.
2622 (installed_h_files): Put in alphabetical order.
2623 Remove duplicate entries for markers.h and unif.h.
2624 (c_files): Remove duplicate entries for markers.c.
2625 (ancillary): Renamed from anillery; all uses changed. Remove
2626 PLUGIN; it's a directory, and needs special treatment in dist-dir.
2627 Remove all the ../doc/* files; doc/Makefile.in handles that.
2629 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
2631 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
2632 every if must have an else, or else the whole command has a
2633 non-zero exit code whenever the if's condition is false.
2635 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
2637 * posix.c: include string.h.
2639 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2641 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
2644 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
2645 Remove leading % from scheme names.
2646 Do not return error values, call SCM_SYSERROR or similar.
2648 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
2650 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
2652 * struct.c (scm_init_struct): new file.
2654 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
2656 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
2657 (scm_list_head): added list-head for rapidly chopping argument
2658 lists off of longer lists (and similar).
2660 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
2662 * objprop.c (scm_object_property): assq the cdr of the whash
2663 handle for obj, not the handle itself.
2665 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
2667 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
2668 weak hash tables last of all marking to avoid an obscure gc bug.
2669 WARNING: circular lists stored in a weak hash table will hose us.
2671 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
2673 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
2674 new functions similar to scm_substring_move_left_x and
2675 scm_substring_move_right_x.
2677 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
2679 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
2682 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
2684 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
2686 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
2688 * strports.c (scm_strprint_obj): convenience function. C for
2689 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
2691 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
2692 removed to a separate library
2694 * init.c (scm_boot_guile): copied from guile-tcl.c.
2695 Initialization specific to tcl interpreters removed.
2697 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
2699 * ports.c (scm_ports_prehistory): size malloced here doesn't
2700 matter so long as it is non-0 (got rid of "* 4").
2702 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
2704 * gscm.h: gscm_mkarray eliminated (presumably was not being used
2705 since its definition was bogus).
2707 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
2709 * mallocs.[ch]: back again (for rx at least).
2711 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
2713 * ports.c: removed functions relating to the mapping between ports
2714 and descriptors. (That stuff is unix-specific and should be collected
2715 in a separate library).
2717 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
2718 (Tom Mckay@avanticorp.com)
2720 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
2722 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
2723 handled correctly (SCM_FREEP was applied to them) -- test for
2724 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
2725 being overwritten with #f. (brown@grettir.bibliotech.com)
2727 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
2729 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
2730 for a specific symbol or for all symbols.
2732 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
2734 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak

2739 * list.c (scm_last_pair): map '()=>'()
2741 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>

2744 Generalized assoc and hash-table functions.
2745 Factored pairs.c into multiple files.
2747 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
2749 * gscm.c (gscm_run_scm): got rid of objprop.
2751 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
2753 * genio.c (scm_getc):
2754 NOTE: fgetc may not be interruptable.
2756 * procprop.c (scm_stand_in_scm_proc):
2757 NOTE: don't use a alist here.
2758 (scm_set_procedure_properties_x): fix type checking throughout this file.
2760 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
2762 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
2763 after freeing part of the port table.
2765 Thu Feb 29 16:21:17 1996 Tom Lord <lord@beehive>
2767 * strports.c (scm_mkstrport):
2768 * vports.c (scm_make_soft_port): allocate a port table entry
2769 (possibly triggering gc) before setting the tag of the corresponding
2772 * pairs.c (scm_delq_x): never throw an error.
2774 * vectors.c (scm_make_vector): made the default vector fill argument
2775 into '() (much more useful than the previous value, "#unspecified")
2777 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
2779 * ports.c (scm_add_to_port_table): Added fields
2780 to port table entries: file_name, line_num, col.
2781 Update these in open_file, gen_getc and gen_ungetc.
2782 Added procedures to access those fields.
2784 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
2786 * procs.c (scm_make_subr_opt): new entry point for making
2789 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
2791 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
2793 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
2795 * numbers.c (scm_exact_p): This function no longer
2796 implements "integer?".
2798 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
2800 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
2801 (scm_gc_stats): return an assoc of useful data. Replaces "room"
2802 and the stats reporting formerlly built into repl.
2804 * repl.[ch]: removed.
2805 GC statistics keeping moved to gc.c.
2806 Other statistics keeping can be done from Scheme.
2807 REPLS are now written in Scheme.
2809 Wed Feb 21 10:28:53 1996 Tom Lord <lord@beehive>
2811 * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky
2812 conservatively marked objects).
2814 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
2816 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
2818 * feature.c (scm_compiled_library_path): moved here from repl.c.
2819 This file is for stuff relating specifically to Scheme libraries
2822 * eval.c (scm_m_define): don't give warning about redefinition, don't
2825 NOTE: this should throw a resumable exception with parameters --
2826 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
2828 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
2830 * error.c: scm_warn eliminated.
2832 * read.c (scm_lreadr): extra right paren gets an error, not a warning.

2835 lose exit_report, growth_mon.
2837 * gscm.c: got rid of verbosity functions.
2839 Tue Feb 20 00:19:10 1996 Tom Lord <lord@beehive>
2841 * throw.c (scm_ithrow): guard against the bad-throw hook changing
2842 between the call to procedurep and use.
2844 * error.c (scm_everr):
2846 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
2849 * strports.c: don't reveal the port's string to the caller
2850 because it changes size.
2852 (stputc stwrite): check/change the strings length with interrupts
2855 * objprop.c (scm_set_object_property_x &c): use the generic
2856 hashing functions and be threadsafe.
2858 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
2859 (per suggestion jaffer@gnu.ai.mit.edu).
2861 * mbstrings.c (scm_multi_byte_string): guard against argument list
2864 * strings.c (scm_make_string): loop cleanup
2866 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer
2869 * weaks.c (scm_weak_vector): guard against argument list
2872 * variable.c (scm_builtin_variable): check for/make a built-in
2875 * vectors.c (scm_vector): while filling the new array,
2876 guard against a list of fill elements that grows after
2877 the vector is allocated.
2879 * hashtab.c -- new file: general hash table
2880 functions. hash, hashq, hashv, hashx.
2882 * tags.h: made wvect an option bit of vector.
2884 Mon Feb 19 09:38:05 1996 Tom Lord <lord@beehive>
2886 * symbols.c: made the basic symbol table operations atomic.
2888 * root.c &c.: collected stack-specific global state.
2889 linum/colnum etc *should* be port-specific state.
2891 * struct.c (scm_init_struct): init the first struct type during
2892 initialization to fix a race condition.
2894 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
2895 object, not in a global.
2896 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
2898 * throw.c (_scm_throw): Pass throwval on the stack, not in a global
2899 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
2901 * *.[ch]: namespace cleanup. Changed all (nearly) exported CPP
2902 and C symbols to begin with SCM_ or scm_.
2904 Sun Feb 18 15:55:38 1996 Tom Lord <lord@beehive>
2906 * gsubr.c (scm_gsubr_apply): statically allocate the
2907 array of arguments (bothner@cygnus.com).
2909 Sat Feb 17 20:20:40 1996 Tom Lord <lord@beehive>
2911 * scmsigs.c: Simplified to use async rountines.
2913 * async.c: New support for interrupt handlers.
2915 Thu Feb 15 11:39:09 1996 Tom Lord <lord@beehive>
2917 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
2918 set the multi_byte flag correctly in symbols. This is wrong.
2919 intern_obbary_soft and msymbolize should take an extra parameter.
2920 Also, weird multibyte symbols don't print correctly.
2921 The weird symbol syntax is also a bit bogus (emacs doesn't quite
2924 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
2926 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
2927 use the system symhash. == #t means create an uninterned symbol.
