[bpt/guile.git] / libguile / ChangeLog
1 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
2
3 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
4 1. mark_lazy_catch didn't mark the smob.
5 2. Both functions above have standard variants:
6 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
7 free_lazy_catch --> scm_free0.
8
9 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
10
11 * throw.c (scm_internal_lazy_catch): New function.
12 (scm_lazy_catch): Rewritten to use it.
13 (scm_ithrow): Handle the new lazy catch representation.
14 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
15 that doesn't have a jmpbuf is a lazy catch clause.
16 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
17 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
18 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
19 smob.
20 (scm_init_throw): Register the new lazy-catch smob type.
21 * throw.h (scm_internal_lazy_catch): decl for new function.
22
23 * throw.c (scm_internal_catch): Doc fixes.
24
25 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
26 configure.in. Including this might cause problems if applications
27 that link against libguile include their own copies of alloca, but
28 if they're using autoconf, they should be adding libguile to LIBS
29 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
30 the copy in libguile, and things will be okay. (I think.)
31
32 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
33
34 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
35 unif.c.
36 strop.h: move prototypes too.
37
38 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
39
40 * posix.c (scm_init_posix): don't intern EINTR since it's now done
41 elsewhere.
42
43 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
44 etc. I deleted them from filesys.c long ago, but didn't
45 notice they were here too (although ineffective since
46 sys/stat.h wasn't included).
47
48 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
49
50 * eval.c: Don't define alloca in GCC case. gcc will automatically
51 use __builtin_alloca if appropriate.
52
53 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
54
55 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
56 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
57 that values of automatic variables are preserved. See comments
58 for safe_setjmp for details.
59
60 Change from Thomas Morgan:
61 * variable.c: Include eq.h.
62 (var_equal): New function.
63 (variable_smob): Use var_equal as the discriminator for variables.
64
65 * throw.c (s_throw): Remove extraneous declaration.
66
67 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
68 * eval.c: Add necessary CPP cruft to support that.
69 * configure, Makefile.in, scmconfig.h.in: regenerated.
70
71 Change from Thomas Morgan:
72 * procprop.c (scm_procedure_properties): Convert the Scheme
73 boolean returned by scm_procedure_p into a C boolean before using
74 it as a condition for SCM_ASSERT.
75 (scm_procedure_property): Likewise.
76
77 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
78 indications of Unixness.
79 * stime.c: Same.
80
81 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
82
83 * * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
84
85 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
86
87 * read.c (scm_lreadr): use scm_misc_error to improve one of the
88 "unknown # object" error messages.
89
90 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
91 (scm_i_index) and declare it static. Add a 'direction' argument
92 to indicate what way the search should go.
93 (scm_i_index): throw out-of-range error instead of wrong-type-arg
94 if indices are bad.
95 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
96 strop.h: remove scm_i_index, scm_i_rindex prototypes.
97
98 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
99
100 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
101
102 * * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
103 to avoid clash with various scsh forks.
104
105 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
106
107 The following two changes (ramap.c, throw.c) are motivated by the
108 apparent unportability of forward declarations of static arrays of
109 the form `static foo bar[];'.
110
111 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
112 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
113
114 * throw.c (scm_throw): Moved above scm_ithrow.
115
116 * options.h: Removed the extern declarations of scm_yes_sym and
117 scm_no_sym since these are static.
118
119 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
120
121 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
122
123 * Makefile.am: remove AWK=@AWK@.
124 Add a rule for generating errnos.list.
125 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
126
127 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
128 don't extract errnos, just set a variable (avoids the
129 need to recompile error.c just because configure is run.)
130
131 * unif.h: update prototypes.
132 * unif.c (scm_uniform_array_read,write): change the offset and
133 length arguments to start and end, for consistency.
134
135 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
136
137 * ioext.h: update prototypes.
138 * * ioext.c (scm_read_delimited_x): replaces scm_read_line and
139 scm_read_line_x, it's a more general procedure using an
140 interface from scsh. read-line and read-line! are now defined
141 in boot-9.scm.
142 * Note that the new read-line trims the terminator
143 by default, previously it was appended to the returned string. An
144 optional argument specifies how to process the terminator (scsh
145 compatible). For the old behaviour: (read-line port 'concat).
146 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
147 returns a pair, but is converted to multiple values if the scsh
148 module is loaded.
149
150 socket.h: update prototypes.
151 * socket.c (scm_recvfrom): for consistency with other procedures,
152 take start and end as separate optional arguments.
153 * (scm_recv, scm_recvfrom): don't allow the second argument
154 to be a size, only a buffer. Change the scheme names to
155 recv! and recvfrom!. Don't return the buffer.
156
157 * ioext.h, posix.h: move prototypes too.
158 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
159 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
160 "read.h" and "unif.h".
161 * ioext.c: include "chars.h"
162
163 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
164
165 * dynl.c: The dynamic linking and module registration functions
166 are now defined even when dynamic linking is not available for the
167 host system. Some of their functionality can be done without
168 dynamic linking; when it's really needed, they throw errors.
169
170 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
171
172 * configure.in: Only define DYNAMIC_LINKING when one of the system
173 dependent functions is detected.
174 * dynl.c (scm_dynamic_func): New function to get the address of a
175 function in a dynamic object.
176 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
177 produced by scm_dynamic_func as the thing to call.
178
179 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
180
181 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
182 (scm_register_module_xxx, scm_registered_modules,
183 scm_clear_registered_modules): New functions.
184
185 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
186
187 * symbols.c (scm_sysintern): Renamed to
188 scm_sysintern_no_module_lookup.
189 (scm_sysintern): New function to take the place of the old
190 scm_sysintern. It uses the current toplevel lookup closure to give
191 the symbol its value. This is a temporary hack to put packages
192 like gtcltk into their own module.
193 (scm_can_use_top_level_lookup_closure_var): New variable to tell
194 us whether `scm_top_level_lookup_closure_var' has been initialized
195 and is usable.
196 * eval.c (scm_init_eval): Set it.
197
198 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
199
200 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
201 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
202 SCM_FD.
203 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
204 scm_syserror_msg.
205 * (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
206 scm_sys_dup): deleted: FD capability will be added to other
207 procedures.
208 * Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
209 scm_fd_free, fd_smob, scm_intern_fd.
210 * (scm_open): renamed from scm_sys_open. Return a port instead of
211 an FD object. Make the mode argument optional.
212 * (scm_sys_create): deleted, it's just a special case of open.
213 (scm_init_filesys): move interning of constants O_CREAT etc.,
214 here (were previously using SCM_CONST_LONG macro).
215 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
216 don't newsmob fd.
217 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
218 include "fports.h" and <stdio.h>
219 (scm_stat, scm_select): don't support FD objects.
220
221 * error.h: adjust scm_syserror_msg prototype.
222 * error.c (scm_syserror_msg): take an extra argument for errno.
223 Using the global value didn't always work, since it could be
224 reset by procedure calls in the message or args arguments.
225
226 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
227 I don't understand why the check was there (and what about the
228 ultrix check?)
229
230 * strop.c (scm_string_copy): allow shared substrings to be copied.
231
232 * unif.h: corresponding change to prototypes.
233 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
234 recognize two new optional arguments: offset and length. Allow
235 the port argument to be an integer (file descriptor, for scsh).
236 Include <unistd.h> for "read" prototype.
237
238 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
239
240 * socket.c: don't include filesys.h.
241
242 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
243
244 * Makefile.am: add AWK=@AWK@ (?)
245
246 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
247 errnos_get.c.
248 Add a rule to generate errnos.c from errnos.
249 * error.c (scm_init_error): include errnos.c.
250 * errnos_cnvt.awk: new file, converts the list of errno codes to
251 C expressions.
252 * errnos_get.c: new file.
253 * errnos.default: new file, contains errnos to try if they can't
254 be extracted from errno.h.
255 * configure.in: if using GCC, try and extract errno codes from
256 errno.h.
257 Added AC_PROG_AWK.
258
259 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
260
261 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
262 * Makefile.am: Made libguile into a libtool library.
263 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
264 Set libtool_libs to indicate that libguile is a libtool library.
265 See guile/ChangeLog for details.
266 * .cvsignore: ignore "*.lo", the libtool library objects.
267
268 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
269
270 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
271 use htons in getservbyport argument.
272
273 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
274
275 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
276 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
277 duplicate.
278
279 * objprop.c (scm_object_property): No need to take the CDR of the
280 value returned by scm_object_properties, since Aug 20 change.
281
282 * configure.in: When checking for struct linger, #include
283 <sys/types.h> as well as <sys/socket.h>. I've never known
284 <sys/types.h> to cause any portability problems, and Solaris's
285 <sys/socket.h> needs it.
286 * configure: Rebuilt.
287
288 I think the Sun compiler has chosen a perverse way to interpret
289 ANSI declarations combined with K&R definitions. We'll
290 appease it a little bit. But when it invades France, we fight.
291 * print.c (scm_iprlist): Change 'tlr' argument to an int.
292 * print.h (scm_iprlist): Here too.
293 * numbers.c (scm_divbigdig): Change definition to match
294 declaration in numbers.h.
295 * unif.c (scm_makflo): Change definition to match declaration in
296 unif.h.
297
298 * init.c (scm_boot_guile): Don't return the value of
299 scm_boot_guile_1. This function doesn't return a value;
300 scm_boot_guile_1 doesn't return a value (or return at all).
301
302 * eval.c (unmemocopy): Add a semicolon to appease the Sun
303 compiler.
304
305 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
306 compile. I have a feeling this function is a bad idea anyway ---
307 one should always test for features, not systems.
308
309 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
310 semicolons. Only pure luck kept this from being noticed earlier.
311
312 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
313
314 * socket.c (scm_recvfrom): Added missing semicolon.
315
316 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
317
318 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
319 the buffer and start and end positions for scsh networking
320 implementation.
321
322 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
323
324 * configure.in: Revert previous change to this file; the problem
325 is due to transient automake weirdness.
326 * configure: Rebuilt.
327
328 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
329 PLUGIN/guile.libs. configure generates the latter from the former.
330 * Makefile.in: Rebuilt.
331
332 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
333 need this if we install scripts, like guile-snarf.
334 * configure: Rebuilt.
335
336 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
337
338 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
339
340 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
341
342 * socket.c (scm_addr_vector): fix faulty scm_listify.
343
344 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
345
346 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
347 style block comment is no longer considered an error.
348
349 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
350
351 * PLUGIN/guile.libs.in: New file.
352 * PLUGIN/guile.libs: Removed from repository.
353 * configure.in: Create PLUGIN/guile.libs from
354 PLUGIN/guile.libs.in. This is for including additonal libraries
355 needed for dynamic linking.
356 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
357 instead of PLUGIN/guile.libs.
358
359 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
360
361 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
362
363 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
364 occurrences of the given element from the list, not just the
365 first. This is how the Emacs Lisp functions behave, how the
366 analogous Common Lisp functions behave, and (I believe) how the
367 older Maclisp functions worked. I realize that this change may
368 break code, but it seemed better to break it before the Guile
369 release than after.
370
371 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
372 Their prototypes were already present in gc.h, but they weren't
373 implemented.
374 (scm_init_storage): Initialize scm_protects.
375 * root.c (scm_protects): New element of scm_sys_protects.
376
377 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
378
379 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
380
381 * libguile.h: Added #include "libguile/net_db.h".
382
383 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
384 30 change. That file is only meant for communication between the
385 configuration process and load.c. If code linked against libguile
386 wants to get at the paths mentioned in libpath.h, it can call
387 functions declared in load.h.
388
389 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
390
391 * libguile.h: Removed #include "libguile/fdsocket.h"
392
393 * net_db.c: Added #include <sys/socket.h>.
394
395 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
396
397 * filesys.c (scm_input_waiting_p): use select in preference to
398 FIONREAD, since the latter doesn't detect EOF.
399 Throw error if neither select nor FIONREAD available.
400
401 * socket.c (scm_connect): take a port, not a fd object.
402 (scm_fill_sockaddr): throw an error if fam is not recognised.
403 (scm_bind): use scm_fill_sockaddr.
404 (scm_listen): take a port, not a fd object.
405 (scm_accept): take and return a port. return #f in the car if
406 address can't be got
407 (scm_sock_fd_to_port): new procedure.
408 (scm_socket): use scm_sock_fd_to_port.
409 (scm_addr_vector): throw error if unrecognised address type.
410 take an extra argument with the calling procedure name.
411 (scm_getsockname): take a port. return #f if address can't be got.
412 (scm_getpeername): take a port. return #f if address can't be got.
413 (scm_recvfrom): take a port. return #f for address component if can't
414 be got.
415 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
416 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
417
418 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
419
420 * throw.c (scm_internal_catch): Make body funcs and handler funcs
421 use separate data pointers, to allow them to be designed
422 independently and reused.
423 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
424 Renamed from catch_body, catch_handler, and uncaught_throw; made
425 generically useful.
426 (struct scm_catch_body_data): Renamed from catch_body_data; moved
427 to throw.h.
428 (scm_catch): Use the above.
429 (scm_throw): Don't bother printing a message for an uncaught
430 throw; we establish a default handler in init.
431 * throw.h (scm_internal_catch): Prototype updated.
432 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
433 decls.
434 (struct scm_body_thunk_data): New structure, used as data
435 argument to scm_body_thunk.
436 * init.c (struct main_func_closure): New structure, packaging up
437 the data to pass to the user's main function.
438 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
439 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
440 scm_internal_catch to establish a catch-all handler, using
441 scm_handle_by_message. This replaces the special-case code in
442 scm_throw.
443 (invoke_main_func): Body function for scm_internal_catch; invoke
444 the user's main function, using the main_func_closure pointer to
445 decide what to pass it.
446 * root.c (struct cwdr_body_data): Remove handler_proc member.
447 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
448 (cwdr_handler): Removed.
449
450 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
451
452 * socket.h (SCM_P): update bind prototype.
453 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
454 include "feature.h".
455 (scm_socket): return a port, not a file descriptor object.
456 include "fports.h" and <unistd.h>
457 (scm_bind): take a port, not a file descriptor object.
458 take an extra argument for address args.
459
460 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
461 INADDR_NONE, INADDR_LOOPBACK.
462
463 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
464
465 * init.c: include net_db.h and not fdsocket.h.
466 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
467
468 * Makefile.am: corresponding changes.
469 * socket.h: renamed from fdsocket.h, fix names.
470 * net_db.h: renamed from socket.h, fix names.
471 * socket.c: renamed from fdsocket.c.
472 remove _sys from procedure names.
473 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
474 add "socket" to features list.
475 * net_db.c: renamed from socket.c.
476 remove _sys from procedure names.
477 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
478 add "net-db" to features list.
479 include "net_db.h". don't include <sys/socket.h> or
480 <sys/un.h>.
481
482 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
483
484 * tags.h (scm_tags): Removed comma at end of last enumerator.
485
486 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
487
488 Don't use GCC extensions to allocate space for debugging frames.
489 (Here he goes again! Why do we put up with this?!)
490 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
491 an scm_debug_info structure, not an in-line array of them. Add
492 'info' member, to say how many vect elements we've used, for eval
493 frames.
494 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
495 a new variable debug_info_end to mark the end of vect, instead of
496 the address of the 'info' pointer itself.
497 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
498 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
499 (SCM_APPLY): Explicitly allocate space for debug.vect.
500 * debug.c (scm_m_start_stack): Same, for vframe.vect.
501 * stacks.c: Adjusted for new debug frame structure.
502 (RELOC_INFO, RELOC_FRAME): New macros.
503 (stack_depth, read_frames): Use them, and new scm_debug_frame
504 element 'info', instead of magically knowing that eval frames have
505 an info pointer sitting after vect.
506 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
507 RELOC_FRAME.
508 (scm_init_stacks): Formatting tweaks.
509
510 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
511
512 Give GCC more control flow information, so it can be sure that
513 variables aren't used uninitialized.
514 * error.h (scm_error, scm_syserror, scm_syserror_msg,
515 scm_sysmissing, scm_num_overflow, scm_out_of_range,
516 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
517 scm_misc_error): Tell GCC that these functions never return.
518 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
519 out the field type, call abort if SCM_ASSERT returns, to placate
520 the optimizer.
521 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
522 scm_wta ever returns. We can't handle this case anyway, and this
523 gives the optimizer more information.
524 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
525 scm_wta ever returns.
526
527 In some cases, the code is fine, but GCC isn't smart enough to
528 figure that out; this usually happens when one variable is only
529 initialized and used when a particular condition holds true, and
530 we know that condition will never change within a given invocation
531 of the function. In this case, we simply initialize the variables
532 to placate the compiler, hopefully to a value which will cause a
533 crash if it is ever actually used.
534 * print.c (scm_iprin1): Initialize mw_pos.
535 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
536 * throw.c (scm_ithrow): Initialize dynpair.
537 * unif.c (scm_uniform_vector_ref): Initialize cra.
538 * struct.c (init_struct): Initialize prot.
539 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
540
541 * strports.c (scm_eval_0str): Don't return uninitialized garbage
542 if EXPR contains no expressions.
543
544 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
545
546 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
547 cause an infinite loop (???). So much for the algebraic
548 equivalency of variable-sized arrays and alloca...
549
550 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
551
552 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
553 a SCM boolean, not a C boolean.
554
555 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
556
557 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
558 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
559 rules for raising scm_mtrigger. Previously, unfortunate but not
560 unlikely circumstances could result in almost constant invokation
561 of the gc. Now, this situations should be less likely, but they
562 are not prevented completely.
563
564 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
565
566 * numbers.c (scm_fuck): Procedure removed; looks like old test
567 code.
568 * numbers.h: Prototype removed.
569
570 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
571
572 * debug.h (scm_debug_frame): Change `vect' member from an in-line
573 array to a pointer, to match my Nov 21 change in eval.c.
574
575 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
576
577 * libguile.h: Added #include "libguile/backtrace.h", #include
578 "libguile/stacks.h".
579
580 * strings.c (scm_string scm_make_string scm_string_ref
581 scm_string_set_x scm_string_equal_p scm_string_append):
582 Bugfix according to scm patch from Aubrey Jaffer:
583 Corrected long-standing
584 (not (eqv? (integer->char 128)
585 (string-ref (make-string 1 (integer->char 128)) 0)))
586 bug found by John Kozak <jk@noontide.demon.co.uk>.
587
588 * strports.c, strports.h: Make scm_eval_0str return the value of
589 the last expression evaluated (previously, it returned void).
590
591 * strports.c, strports.h: New function: scm_read_0str. Does what
592 it sounds like.
593
594 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
595
596 * simpos.c (scm_getenv): return #f if string can't be found in the
597 environment instead of throwing an exception, for compatibility
598 with numerous other systems.
599
600 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
601
602 * Makefile.am (.c.x): Use guile-snarf.
603 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
604 executable.
605 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
606
607 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
608
609 * backtrace.c (scm_display_error_message): Made non-static, and
610 renamed from display_error_message.
611 * backtrace.h (scm_display_error_message): Added extern decl.
612 * throw.c (uncaught_throw): Use it to display the error message.
613
614 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
615
616 * inet_aton.c: Use #if 0, not #ifdef 0.
617
618 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
619
620 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
621 to convert the returned value.
622 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
623 the offset argument.
624
625 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
626
627 Add new interface to catch/throw, usable from C as well as
628 Scheme.
629 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
630 (scm_internal_catch): New function, replaces...
631 (scm_catch_apply): Deleted.
632 * throw.c (scm_catch_apply): Deleted; replaced with a more general
633 mechanism which is a bit more code, but can be used nicely from C
634 and implement the Scheme semantics as well.
635 (scm_internal_catch): This is the replacement; it's named after
636 the analogous function in Emacs.
637 (scm_catch): Reimplemented in terms of the above.
638 (struct catch_body_data, catch_body, catch_handler): New
639 functions, used by scm_catch.
640 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
641 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
642 support for new cwdr.
643
644 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
645 Oct 30.
646
647 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
648
649 * acconfig.h: Added DYNAMIC_LINKING symbol.
650 * configure.in: Add option and checks for dynamic linking.
651 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
652 dynl.h: New files for dynamic linking support.
653 * Makefile.am (libguile_a_SOURCES):
654 Added "dynl.c".
655 (modinclude_HEADERS): Added "dynl.h".
656 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
657 "dynl-vms.c".
658 * init.c (scm_boot_guile_1): Call
659 scm_init_dynamic_linking to initialize dynamic linking support.
660
661 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
662
663 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
664 (as we Schemers say). It needs to be global, so that I can tweak
665 it for the proper operation of unexec.
666 (scm_boot_guile_1_live): New variable, see above.
667
668 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
669
670 * guile-snarf.sh: Removed.
671 * PLUGIN/guile.libs: Added dependency for -lm.
672 * acinclude.m4: Renamed from aclocal.m4.
673 * PLUGIN/greet: Removed.
674 * Makefile.am, aclocal.m4: New files.
675 * configure.in: Updated for Automake.
676
677 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
678
679 * eval.c (scm_definedp): Use top_level_lookup_closure_var
680 and not top_level_lookup_thunk_var.
681
682 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
683
684 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
685
686 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
687
688 * eval.c (scm_definedp): Incompatibly changed to be a builtin
689 Scheme function, instead of syntax. Single argument is now a
690 symbol.
691
692 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
693
694 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
695 scm_ra_divide): Properly terminate statements passed as arguments
696 to IVDEP macros. (Thanks to Bernard Urban.)
697
698 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
699 with non-constant sizes. (Thanks to Bernard Urban.)
700
701 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
702
703 It's an "eval closure", not an "eval thunk." A thunk is a
704 function of no arguments.
705 * root.h (struct scm_root_state): Renamed
706 top_level_lookup_closure_var from top_level_lookup_thunk_var.
707 (scm_top_level_lookup_closure_var): Renamed from
708 scm_top_level_lookup_thunk_var.
709 * root.c (mark_root): Uses changed.
710 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
711 * init.c (scm_start_stack): Uses changed.
712 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
713 Change scheme-visible name to *top-level-lookup-closure* from
714 *top-level-lookup-thunk*.
715
716 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
717
718 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
719 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
720
721 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
722
723 * gc.c (struct scm_heap_seg_data): Doc fixes.
724
725 * gc.c (scm_gc_sweep): Empty all segments' freelists before
726 sweeping. Then, prepend each segment's free cells to its
727 freelist, rather than wiping out the old value. (Thanks to Marius
728 Vollmer.)
729
730 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
731 scm_check_freelist, scm_debug_newcell): New functions and
732 variables, for debugging freelist problems.
733 * pairs.h (SCM_NEWCELL): New debugging version added.
734 * gc.h (scm_debug_newcell): Added extern declaration, used by
735 debugging version of SCM_NEWCELL.
736
737 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
738
739 On some systems <libc.h> conflicts with <unistd.h>, and should not
740 be #included at all.
741 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
742 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
743 * configure.in: Call it.
744 * posix.c, filesys.c: Use its results to decide whether or not to
745 #include <libc.h>.
746 * configure, scmconfig.h.in: Rebuilt with autoconf and
747 autoheader.
748
749 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
750
751 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
752 pointer to the stdio stream before calling scm_setbuf0, so the
753 latter will be able to retrieve it. I'm surprised this didn't
754 segfault earlier. (Thanks to Christopher Lee.)
755
756 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
757
758 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
759 of `lazy-catch'.
760
761 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
762
763 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
764 number of stack narrowing specifier pairs. The first specifier in
765 a pair controls inner border, the second the outer border. A
766 number means cut that number of frames, a procedure object means
767 cut until that object is found in operator position in a frame.
768
769 * root.c (cwdr): Bugfix.
770
771 * read.c: Recording of positions disabled by default.
772
773 * procs.c (scm_closure_p): New function.
774
775 * posix.c (scm_tmpnam): New function.
776
777 * load.c: Added #include "throw.h".
778 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
779 ends with '/'.
780
781 * load.c, load.h (scm_read_and_eval_x): New function.
782
783 * eval.c: Renamed debug option "deval" to "debug".
784
785 (scm_eval_x): `eval!' is no longer accessible from the scheme
786 level. Motivation: We can't allow operations which introduce
787 glocs into the scheme level. Guile's type system can't handle
788 these as data. Use `eval' or `read-and-eval!' as replacement.
789
790 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
791 SCM_CONSP since this is a macro!; Set vframe.prev to
792 scm_last_debug_frame instead of 0. In this way we can look
793 "above" the virtual start stack frame if we wish.
794 (scm_debug_hang): New function: Useful for debugging Guile in
795 certain tricky situations. Will probably be removed later...
796
797 * debug.h: Changed semantics of debug option "backtrace". This
798 option now only indicates whether we want automatic backtrace at
799 an error.
800
801 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
802
803 * ports.c: #include "filesys.h"
804 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
805
806 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
807 Motivation: This is system specific code which is related to file
808 I/O. It also may use select. Added code by Gary Houston to
809 detect presence of character in stdio buffers.
810
811 * libguile.h: #include "libguile/libpath.h"
812
813 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
814 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
815 SCM_SITE_DIR; Install libpath.h among the other include files.
816
817 * load.c, load.h (scm_sys_package_data_dir): New function.
818
819 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
820
821 * stacks.h: Bugfix: Don't use tail-array length field as stack
822 length field! This screwed GC.
823
824 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
825
826 * _scm.h: Added #ifndef around definition of macros min and max.
827
828 * __scm.h: Added hooks for threads to plugin to in ints protection
829 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
830 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
831 the main code in these macros duplicated and spread over multiple
832 files. Renamed SCM_THREADS_SWITCHING_CODE ->
833 SCM_THREAD_SWITCHING_CODE.
834
835 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
836
837 * snarf.h: New file.
838 * guile-snarf.sh: New file.
839 * Makefile.in (inner_h_files): Added snarf.h
840 (ancillary, install, uninstall, distclean): Added actions for
841 guile-snarf.
842 (.c.x): Use guile-snarf.
843 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
844 (gen_c_files): Note that these depend on guile-snarf.
845 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
846 now in "snarf.h". Added #include "snarf.h" to get them.
847 * libguile.h: Added #include "snarf.h".
848 (Patches applied and tweaked by Jim Blandy.)
849
850 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
851
852 * socket.c: Use K&R style declaration for 'close'; the GNU coding
853 standards suggest against providing prototypes for system
854 functions. Thanks to Greg Troxel.
855
856 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
857
858 * strports.c (scm_eval_0str): New function.
859 #include "read.h", to get prototype for scm_read.
860 * Makefile.in (strports.o): Update dependencies.
861 * strports.h: New prototype.
862
863 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
864 scheme name from "int?" to "integer?". It seems to do the job.
865 * numbers.h: Rename prototype too.
866 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
867 hope this is right.
868
869 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
870 scm_num_eq_p): Rename these according to R4RS conventions: call
871 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
872 to making libguile R4RS compliant without ice-9...
873
874 * load.c (scm_sys_search_load_path): Search for files under all
875 extensions listed in the %load-extensions variable. If FILENAME
876 is absolute, return it unchanged, without searching the load path.
877 (scm_loc_load_extensions): New variable, pointing to
878 %load-extensions' value cell.
879 (scm_init_load): Initialize it, and the value it points to.
880 (scm_primitive_load_path): Improve error reporting.
881
882 * load.c (scm_loc_load_hook): New variable, pointing to value cell
883 of new Scheme variable %load-hook.
884 (scm_primitive_load): Apply %load-hook to filename.
885
886 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
887
888 * configure.in: add tests for figuring out whether buffered data
889 is available in a FILE structure, which is needed by char-ready.
890
891 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
892 FILE_CNT_READPTR.
893
894 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
895 exceptions using misc_error instead of syserror. It seems a bit
896 odd to throw an exception if a string can't be found in the
897 environment, but it's consistent with open-file, stat etc.
898 (simpos.h): remove sys_ from getenv.
899
900 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
901 occurs, throw an error instead of returning errno. Return value
902 is now unspecified.
903 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
904
905 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
906
907 * filesys.c (scm_stat2scm): derive file type and permissions from
908 the stat mode and append them to the returned vector.
909 There isn't much overhead in doing this and it avoids the need to
910 work with S_IRUSR et al. in Scheme.
911 Define symbols scm_sym_regular etc.
912 (scm_init_filesys): don't intern S_IRUSR etc.
913
914 * load.c: change s_try_load and s_try_load_path to s_primitive_load
915 and s_primitive_load_path.
916
917 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
918
919 * error.h: don't declare error symbols. prototype for scm_misc_error.
920
921 * stackchk.c (scm_stack_overflow_key): defined here instead of in
922 error.c.
923
924 * error.c: use SCM_SYMBOL to set up error keys.
925 scm_misc_error: new procedure.
926
927 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
928
929 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
930 between `#!' and `!#' is ignored.
931 (skip_scsh_block_comment): New function.
932
933 * feature.c (scm_set_program_arguments): New argument, FIRST.
934 * feature.h: Update prototype.
935 * init.c (scm_boot_guile_1): Pass new argument to
936 scm_set_program_arguments.
937
938 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
939
940 * init.c (scm_start_stack): Don't initialize scm_progargs here.
941 (scm_boot_guile): Call scm_set_program_arguments here, later than
942 the old initialization.
943
944 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
945 initialization procedure.
946 - Delete in, out, err arguments; there are other perfectly good
947 ways to override these when desired.
948 - Delete result argument; this function shouldn't ever return.
949 - Rename init_func argument to main_func, for less confusion.
950 - Delete boot_cmd argument; main_func is more general.
951 -Add 'closure' argument, to help people pass data to main_func
952 without resorting to global variables.
953 - Abort if reentered; don't bother returning an error code.
954 - Call scm_init_standard_ports to set up the default/current
955 standard ports; no need to pass them to scm_start_stack.
956 - Remove code to evaluate the boot_cmd, and start the repl; let
957 the user do something like that in main_func if they want.
958 - Remove code to package up a return value; main_func can do any
959 of that as needed.
960 - Call exit (0), instead of returning.
961 (scm_start_stack): Don't initialize the I/O ports here; that's
962 weird. Delete in, out, err arguments. Move guts to
963 scm_init_standard_ports, scm_stdio_to_port.
964 (scm_init_standard_ports): New function, to set up current and
965 default standard ports.
966 (scm_start_stack, scm_restart_stack): Make these static.
967 * init.h (scm_boot_guile): Adjust declaration.
968 (scm_start_stack, scm_restart_stack): Remove externally
969 visible declarations for these.
970 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
971
972 * fports.c (scm_stdio_to_port): New function. Its guts used to be
973 written out several times in scm_start_stack.
974 * fports.h: New declaration for the above.
975
976 * feature.c (scm_set_program_arguments): New function.
977 * feature.h: New declaration for the above.
978
979 * ports.c: Formatting tweak.
980
981 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
982
983 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
984 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
985 for obtaining the address of a car or cdr field. Motivation:
986 &SCM_CXR make assumptions about the internal structure of the
987 SCM_CXR selectors.
988
989 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
990 Motivation: see SCM_CXRLOC.
991
992 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
993 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
994 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
995 Motivation: Safer use. Some other macros are defined in terms of
996 these operations. If these are defined using the SCM_SETCXR
997 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
998 to inefficiency and an <e1> with side-effects could potentially
999 break. Also, these particular operations are heavily utilized in
1000 the garbage collector. In unoptimized code there will be a
1001 measurable speedup.
1002
1003 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1004 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
1005 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
1006 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
1007 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
1008 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1009 vports.c: Cleaned up use of pairs: Don't make any special
1010 assumptions about the internal structure of selectors and
1011 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1012 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1013 (Among other things, this change makes it easier to build Guile
1014 with certain compilers which have problems with casted lvalues.)
1015
1016 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1017
1018 * stacks.c: Improve selection of relevant stack frames when making
1019 a stack object. Introduce one level of indirection in the stack
1020 object to make it possible to "narrow" to a certain region of the
1021 stack. This facilitates making use of more clever algorithms (not
1022 implemented) for selecting relevant frames and gives a cleaner
1023 design since selection of frames can be done independently of
1024 extraction of frames from the real stack.
1025 (scm_stack_id): Also take #t as argument which means look at
1026 current stack.
1027
1028 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1029 Turn n_tail into an integer directly representing current number
1030 of frames in stack. Add field tail.
1031
1032 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1033
1034 * debug.c (scm_make_memoized): Made it available at scheme level.
1035 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1036 SCM_NIMP before applying heavier predicates in argument checking.
1037 (scm_local_eval): Also take memoized object as argument.
1038
1039 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1040 aren't created with zero length, but should such a strange
1041 creature suddenly turn up...
1042
1043 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1044
1045 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1046 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1047
1048 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1049
1050 * variable.c (scm_make_variable): Make the name hint optional, as
1051 documented.
1052 (anonymous_variable_sym): Renamed from variable_sym. All uses
1053 changed.
1054
1055 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1056 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1057 of scm_primitive_load_path was also changed to
1058 "primitive-load-path", from "%try-load-path". Callers changed.
1059 We'd like to respect the convention that a function named
1060 "try-mumble" should behave just like the function called "mumble",
1061 but return #f instead of signalling some error.
1062 * load.h: Rename prototypes.
1063
1064 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1065
1066 * print.c (make_print_state, grow_print_state), print.h: Modified
1067 the print state representation: Don't use a tail array for
1068 recording of circular references. Resizing of the print state
1069 structure invalidates the print state pointer. To avoid passing
1070 around an indirect print state reference to all printing
1071 functions, we instead let the print state reference a resizable
1072 vector.
1073
1074 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1075
1076 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1077 Don't crash when passed an improper list terminated by a
1078 non-immediate value.
1079
1080 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1081
1082 Allocate data for structures on an eight-byte boundary, as
1083 required by the tagging system.
1084 * struct.c (alloc_struct): New function.
1085 (scm_make_struct, scm_make_vtable_vtable): Call it.
1086 * struct.h (scm_struct_n_extra_words): Bump to 3.
1087 (scm_struct_i_ptr): New "field".
1088 * gc.c (scm_gc_sweep): When we need to free the data, use the
1089 information stored by alloc_struct to find the beginning of the
1090 block allocated to the structure, so we can free it.
1091
1092 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1093
1094 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1095 scm_init_stacks.
1096
1097 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1098 (scm_debug_info): New member: id.
1099
1100 * stacks.c: Stacks are now represented as structs; Stacks have an
1101 id given to them by `start-stack'.
1102 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1103
1104 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1105 Changed stack representation.
1106
1107 * debug.c (scm_procedure_name): Try procedure property `name' for
1108 compiled closures aswell.
1109
1110 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
1111
1112 * eval.c: scm_i_name moved to gsubr.c
1113 (scm_m_define): Record names of all kinds of procedure
1114 objects. (Earlier, only closures were recorded.)
1115
1116 * procprop.h: Added declaration of scm_i_name.
1117
1118 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1119 (scm_make_gsubr): Record names of compiled closures.
1120
1121 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1122
1123 * debug.c, debug.h: Removed obsolete code.
1124
1125 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1126 stacks.c: Renamed regs --> scm_contregs.
1127
1128 * print.c (scm_free_print_state): Cleanup print state before
1129 returning it to pool. It is better to do it here than in
1130 scm_prin1 since scm_prin1 is called often.
1131
1132 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1133 s_set_source_property_x): Check that first argument is a pair or a
1134 memoized object.
1135
1136 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1137 scm_i_line, scm_i_column and scm_i_breakpoint global.
1138
1139 * init.c: Added #include "backtrace.h" and #include "stacks.h".
1140 (scm_boot_guile_1): Added calls to scm_init_backtrace and
1141 scm_init_stacks.
1142
1143 * debug.h: Added debug object smob declaration and macro
1144 definitions.
1145
1146 * configure.in: Build with backtrace.o and stacks.o if debug
1147 support enabled.
1148
1149 * Makefile.in: Added entries for new files: backtrace.c,
1150 backtrace.h, stacks.c and stacks.h.
1151
1152 * symbols.c (scm_sym2ovcell): Fixed documentation.
1153
1154 * _scm.h (min, max): Added.
1155
1156 * async.c: Moved `min' macro to _scm.h.
1157
1158 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1159 SCM_BACKTRACE_INDENT.
1160
1161 * eval.c: Added new debug options `maxdepth' and `indent'.
1162
1163 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
1164
1165 * print.h: Added selector SCM_PRINT_STATE.
1166
1167 * print.c: New functions: scm_make_print_state,
1168 scm_free_print_state.
1169
1170 * print.h: Added declarations for scm_make_print_state,
1171 scm_free_print_state.
1172
1173 * debug.c (scm_m_start_stack): New acro.
1174
1175 * debug.h: Small cleanup.
1176
1177 * init.c (scm_boot_guile_1): Moved scm_init_debug below
1178 scm_init_eval.
1179
1180 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
1181
1182 * __scm.h, alist.c, alist.h, append.c, append.h, appinit.c,

1200 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
1201 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
1202 declare functions with prototypes. (Patch thanks to Marius
1203 Vollmer.)
1204
1205 More prototype-related changes from Marius Vollmer:
1206 * gdb_interface.h: Wrapped header file in #ifdef/#endif
1207 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
1208 * ports.h (ptobfuns): Added prototypes. This means some casting in
1209 fports.c.
1210 * fports.c: Added casts for initializations, since the functions
1211 are defined to take FILE * as their stream argument, not SCM.
1212 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
1213 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
1214 to `char *str_data' to conform to prototype.
1215
1216 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1217
1218 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
1219
1220 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
1221
1222 * stime.c, stime.h: use SCM_P method.
1223
1224 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1225
1226 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
1227 be given at least two arguments. Insist that lst's last element
1228 be a list, but don't make any requirements of its predecessors.
1229
1230 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1231
1232 * eval.c (scm_nconc2last): Revert last change; there seems to be
1233 other stuff going on here.
1234
1235 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1236
1237 * eval.c (scm_nconc2last): Make sure that each element of lst
1238 (which is a list of argument lists, except for the tail) is a
1239 proper list, i.e., finite and terminated by '().
1240
1241 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1242
1243 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
1244 Clarifies flow.
1245
1246 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
1247 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
1248 saying "1".
1249
1250 * vectors.c (scm_make_vector): Fill vectors with the undefined
1251 value, to help make Guile Scheme code more portable to other
1252 Schemes.
1253
1254 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
1255 * symbols.h, tags.h: Doc fixes.
1256
1257 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
1258
1259 * async.c (scm_take_signal): Doc fixes.
1260
1261 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
1262
1263 * numbers.c (scm_divbigint): When the remainder is zero, we don't
1264 want to subtract it from the modulus; we just want to leave it
1265 alone.
1266
1267 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
1268
1269 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
1270 `scm_init_threads'.
1271
1272 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
1273
1274 * throw.c (scm_catch_apply): Finished implementation of
1275 `lazy-catch'.
1276
1277 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
1278
1279 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
1280 check.
1281 (scm_init_filesys): set "i/o-extensions" feature.
1282 include feature.h.
1283
1284 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
1285
1286 * Makefile.in (root.o): Correct dependencies.

1288 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
1289
1290 * Makefile.in: Added dependency entry for root.o.
1291
1292 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
1293 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
1294
1295 * init.c (scm_start_stack): Set initial root continuation number
1296 to 0.
1297
1298 * procs.c: New function: scm_thunk_p.
1299
1300 * procs.h: Added declarations of scm_thunk_p.
1301
1302 * root.c: Renamed `call-with-new-root' -->
1303 `call-with-dynamic-root'.
1304 (cwdr): Removed allocation of new root state. This should be done
1305 separately by use of scm_make_root.
1306 (scm_apply_with_dynamic_root): New function: Does what it
1307 sounds like. Needed when spawning threads.
1308
1309 * root.h: Added member last_debug_frame to root state.
1310 Added #include "libguile/debug.h"
1311
1312 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
1313 arguments. The motivation is that code in root.c needs catch
1314 functionality, and we want to avoid code duplication.
1315 New functions: scm_catch, scm_lazy_catch. These are wrappers for
1316 scm_catch_apply. scm_lazy_catch is intended to introduce catch
1317 handlers that run without popping the stack into the dynwind
1318 chain.
1319
1320 * throw.h: Added prototypes for scm_catch_apply and
1321 scm_lazy_catch.
1322
1323 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1324
1325 * root.h (scm_root, scm_set_root): Decouple thread support details
1326 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
1327 SCM_SET_THREAD_LOCAL_DATA.
1328
1329 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
1330 and tortoise scanning loop.
1331
1332 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
1333
1334 * Makefile.in: Rebuild dependencies.
1335
1336 * libguile.h: #include "libguile/print.h" before "smob.h", since
1337 the latter uses the print_state structure.
1338
1339 * throw.c (scm_ithrow): Use the correct variable when checking to
1340 see if a given element of scm_dynwinds is a valid catch.
1341
1342 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
1343 structure, abort; don't just silently ignore the garbage.
1344
1345 * _scm.h: #include "print.h" here, since it seems to be used just
1346 about everywhere.
1347 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
1348 strports.c, unif.h: Don't #include "print.h".
1349
1350 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1351
1352 * feature.h (scm_loc_features): Removed external declaration.
1353 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
1354
1355 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1356
1357 * feature.c (scm_init_feature): Added threads feature (needs to be
1358 initialized here, since features doesn't exist when
1359 scm_init_threads is called).
1360
1361 * libguile.h: Added #include "libguile/../threads/threads.h".
1362 (This is a kludge to get thread support working. This should be
1363 fixed.)
1364
1365 * configure.in, acconfig.h: Added flags for thread support.
1366
1367 * scmsigs.c: Define `signal' to be `pthread_signal' if using
1368 mit-pthreads.
1369
1370 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
1371 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
1372 root.c:mark_root.
1373
1374 * _scm.h: Added conditional #include "threads.h"
1375
1376 * __scm.h (SCM_ASYNC_TICK): Added call to macro
1377 SCM_THREADS_SWITCHING_CODE.
1378
1379 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
1380 allocate the basic dynamic root object.
1381 (scm_boot_guile): Added call to scm_init_root.
1382
1383 * root.c, root.h: Added root smob.
1384 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
1385 functions: Implements dynamic roots mostly according to spec in
1386 SCM manual. Main difference is that the second argument is a
1387 throw handler rather than an error "thunk".
1388
1389 * root.h: Added declaration of scm_init_root.
1390
1391 * root.c: Added #include "genio.h", #include "smob.h", #include
1392 "pairs.h", #include "throw.h", #include "dynwind.h", #include
1393 "eval.h"
1394 (scm_init_root): Added #include "root.x".
1395
1396 * throw.c: Added #include "stackchk.h"
1397 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
1398 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
1399 can be used in scm_call_with_new_root; Added reenabling of stack
1400 checking when catching a throw.
1401
1402 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
1403
1404 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
1405
1406 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
1407 element is not found, as per R4RS.
1408
1409 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1410
1411 * list.c: Doc fixes throughout.
1412
1413 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1414
1415 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
1416 declare the char * to be const. Avoids a warning in rgx.c.
1417
1418 * ports.h: spelling fix.
1419
1420 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
1421 error messages.
1422
1423 * load.c (scm_sys_try_load_path): throw an error if file not found
1424 (like it says it in NEWS).
1425
1426 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1427
1428 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
1429 PROPS slot to '(), not #f; it's an empty alist.
1430
1431 * throw.h, throw.c: Use SCM_P instead of #if hair.
1432
1433 Remove special support for uncaught throws; see throw.c for
1434 rationale.
1435 * throw.c (uncaught_throw): New function.
1436 (scm_ithrow): Call uncaught_throw if we don't find a throw
1437 target; don't mess with scm_bad_throw_vcell.
1438 (scm_bad_throw_vcell): Variable deleted.
1439 (scm_init_throw): Don't initialize it.
1440
1441 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
1442 #t catches.
1443
1444 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1445
1446 * numbers.c (scm_istr2int): If the number is short (as most
1447 numbers are), just call scm_small_istr2int to deal with it.
1448 (scm_small_istr2int): New function, created by un-#ifdefing the
1449 non-bignum version of scm_istr2int and renaming it.
1450
1451 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
1452
1453 * load.c (scm_sys_try_load): don't check whether value returned
1454 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
1455 Change the Scheme name from %try-load to primitive-load.
1456
1457 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
1458 Can avoid passing a message, allowing it to be derived in the
1459 error handler (e.g., if we want to throw to the key both from
1460 Scheme and C).
1461
1462 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
1463
1464 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
1465 references now have a new appearance which is more compact and
1466 also gives a clue about what the target of the reference is.
1467 By setting parameters in the print state, more fancy printing can
1468 be achieved. This is used by the (not yet commited) backtrace
1469 code.
1470
1471 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
1472
1473 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
1474 "print.h"
1475
1476 * print.c: Added #include "struct.h". Removed function
1477 scm_prlist.
1478
1479 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
1480 scm_iprin1. Removed prototype for scm_prlist.
1481
1482 * arbiters.c (prinarb),
1483 async.c (print_async),
1484 debug.c (prindebugobj, prinmemoized),
1485 eval.c (prinprom, prinmacro),
1486 filesys.c (scm_fd_print, scm_dir_print),
1487 kw.c (print_kw),
1488 mallocs.c (prinmalloc),
1489 numbers.c, numbers.h (scm_floprint, scm_bigprint),
1490 smob.h (scm_smobfuns),
1491 srcprop.c (prinsrcprops),
1492 throw.c (prinjb),
1493 unif.c, unif.h (scm_raprin1, rapr1),
1494 variable.c (prin_var): Changed argument `int writing' to
1495 `scm_print_state *pstate'.
1496
1497 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
1498 that it will be called before scm_init_print.
1499
1500 * print.c (scm_prin1): Print states are now allocated when calling
1501 scm_prin1 and then passed around to all printing functions as an
1502 argument. A cache `print_state_pool' enables reuse of print
1503 states.
1504 (scm_make_print_state): New function.
1505 (scm_iprin1): Adaption to print states.
1506 (scm_iprlist): An initial "hare and tortoise" scan brings down
1507 time complexity to O (depth * N). (Better time complexity will be
1508 achieved when the printing code is completely rewritten.)
1509
1510 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1511
1512 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
1513 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
1514 it gets done whether or not the cache variable has a value.
1515
1516 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
1517
1518 Distinguish #f and ().
1519 * __scm.h: #undef SICP.
1520 * pairs.h (SCM_EOL): Delete this definition, equating it with
1521 SCM_BOOL_F.
1522 * tags.h (SCM_EOL): Give it a new definition here; I think I found
1523 the value it used to have. Doc fixes, too.
1524
1525 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
1526
1527 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
1528 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
1529 Lord's implementation of structs, allowing for tail arrays as
1530 described in the manual. Also fixed some bugs. (Both the interface
1531 and the implementation should be improved.)
1532
1533 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
1534
1535 * print.c, print.h: Closures now print like #<procedure foo (x)>.
1536 People who whish to see the source can do `(print-enable 'source)'.
1537 Removed #ifdef DEBUG_EXTENSIONS.
1538
1539 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1540
1541 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
1542 integer (assuming for now accepting an integer is a good thing).
1543
1544 * error.c, fports.c: replace use of %S in lgh_error args with %s.
1545 %S will be used instead for write'ing arguments.
1546
1547 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
1548 asserts. fix a few other asserts.
1549 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
1550 scm_uniform_vector_ref, scm_array_set_x,
1551 scm_dimensions_to_unform_array): change args in
1552 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
1553 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
1554 scm_substring_fill_x): likewise.
1555 gsubr.c (scm_gsubr_apply): likewise.
1556 eval.c (SCM_APPLY): likewise.
1557
1558 * eval.c (4 places): replace scm_everr with lgh_error or
1559 scm_wrong_num_args.
1560
1561 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
1562 scm_memory_error): new procedures.
1563 scm_everr: deleted. can use scm_wta, dropping first two args.
1564 scm_error: convert NULL subr to SCM_BOOL_F.
1565
1566 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
1567 SCM_ARGERR.
1568
1569 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
1570 of scm_wta.
1571
1572 * error.c, error.h: new error keys: scm_arg_type_key,
1573 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
1574 scm_misc_error_key.
1575 scm_wta: reimplement using lgh_error instead of scm_everr.
1576
1577 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
1578
1579 * gdbint.c: scm_lread now has one more argument.
1580
1581 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
1582 scm_port_\1; Added mutator scm_set_port_filename_x (used when
1583 loading source from non-file ports, which, e. g., happens when
1584 using the Emacs interface).
1585
1586 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
1587 object.
1588
1589 * read.c: Added code for recording of positions of source code
1590 expressions; New functions: recsexpr, scm_lreadrecparen;
1591 _scm_make_srcprops --> scm_make_srcprops
1592 (scm_flush_ws): Removed updating of positions counters. This work
1593 is already done by scm_gen_getc
1594
1595 * read.h: Added prototype for scm_lreadrecparen
1596
1597 * print.c: Added #include "alist.h"
1598
1599 * eval.c: Added #include "hash.h"
1600
1601 * eq.c: Added #include "ramap.h"
1602
1603 * options.c: Documentation fixes.
1604
1605 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
1606 (scm_init_srcprop): Adjusted size of initial source-whash. Name
1607 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
1608 --> scm_make_srcprops
1609
1610 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
1611 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
1612 function calls in the definition of the whash access macros.
1613
1614 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
1615
1616 * init.c (scm_boot_guile): Add level of indirection to
1617 scm_boot_guile_1() to ensure that stack base pointer is properly
1618 initialized. There was no guarantee that variable i was the
1619 highest/lowest variable on stack (i.e. the call frame of
1620 scm_boot_guile was not completely protected from gc).
1621
1622 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
1623
1624 * ports.h (scm_port_table): put back file_name, it will be used to
1625 support debugging. Undo related changes in fports.c, ioext.c,
1626 ports.c, gc.c.
1627
1628 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1629
1630 * ports.h (scm_port_table): remove file_name member for now, it seems
1631 undesirable.
1632 * fports.c (scm_open_file): don't set file_name in PTAB.
1633 (prinfport): don't use file_name in PTAB.
1634 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
1635 * ports.c (scm_add_to_port_table): don't intialize file_name.
1636 (scm_port_file_name): remove for now.
1637 * gc.c (scm_gc_mark): don't mark PTAB file_name.
1638
1639 * fports.h (scm_mkfile): prototype deleted.
1640 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
1641
1642 * debug.c, unif.c: use scm_out_of_range instead of
1643 wta for range errors (ASSERT still needs work).
1644
1645 * error.c, error.h (scm_out_of_range): new procedure.
1646
1647 * error.c, error.h (scm_out_of_range_key): new key.
1648
1649 * posix.c (scm_sync): #else was missing.
1650
1651 * error.c, error.h: append _key to names scm_num_overflow and
1652 scm_system_error.
1653
1654 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
1655 of consing an empty list.
1656 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
1657 of macros, saves code and string space.
1658 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
1659 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
1660 lower case. Rename scm_syserror_m to scm_syserror_msg.
1661 error.h: prototypes for new procedures.
1662
1663 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
1664
1665 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
1666
1667 * error.c, error.h: setup scm_num_overflow key.
1668
1669 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
1670 Remove definition of SCM_OVSCM_FLOW.
1671
1672 * fports.c (scm_open_file): use SCM_SYSERROR_M.
1673
1674 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
1675 explicit message and args.
1676
1677 * error.c, error.h, __scm.h: change system_error_sym to
1678 scm_system_error.
1679
1680 * error.c (system_error_sym): remove leading %% from the Scheme name
1681 "%%system-error".
1682
1683 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
1684
1685 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1686
1687 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
1688 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
1689 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
1690 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
1691 renamed. (These were introduced by unsupervised name
1692 substitution.)
1693
1694 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1695
1696 * print.c: Added code for detection of circular references during
1697 printing. (init_ref_stack, grow_ref_stack): New functions. Added
1698 a hook for printing of closures (accessible via print options).
1699 This leads to a split of calls to scm_iprin1 into two classes:
1700 elementary print operations (e. g. the code which prints a smob)
1701 still use scm_iprin1 while top level calls (like scm_display) use
1702 scm_prin1. scm_prin1 begins by clearing the data structure used
1703 to record reference information.
1704
1705 * print.h: Added declarations of scm_prin1 and scm_prlist.
1706
1707 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
1708
1709 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
1710
1711 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
1712
1713 * error.c (err_head): scm_iprin1 --> scm_prin1
1714
1715 * debug.c: Adjusted header comment.
1716
1717 * tags.h: Typo.
1718
1719 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1720
1721 * strerror.c: Doc fix.
1722
1723 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1724
1725 * gdbint.c (gdb_read): Now possible to run during GC.
1726 (unmark_port, remark_port): New functions.
1727
1728 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
1729
1730 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
1731 of allocating a new string object. Also, increase size by
1732 the factor 2 instead of 1.5.
1733
1734 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
1735
1736 * __scm.h (SCM_P): Corrected to run under traditional C.
1737
1738 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
1739 removed.
1740
1741 * async.c: Calls to scm_sysintern corrected.
1742
1743 * async.h (scm_async_clock): Redundant declaration removed.
1744
1745 * continuations.c (scm_dynthrow): Redundant declaration removed.
1746
1747 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
1748 Definition typos corrected.
1749
1750 * debug.h: Missing declarations of functions in debug.c added
1751 (lots).
1752
1753 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
1754 Missing declarations to functions in eval.c added.
1755
1756 * filesys.c: Possibly uninitialized variable rv.
1757
1758 * gc.h (scm_object_addr, scm_unhash_name): Missing
1759 declarations of functions defined in gc.c added.
1760
1761 * genio.c: Possible typos str_data -> wstr_data. ???
1762
1763 * genio.c: Possibly unintended shadowing of local variable
1764 `int c' (gotos out of scope of inner `c'). ???
1765
1766 * init.c: Uninitialized `SCM last' may be used.
1767
1768 * ioext.h: (scm_sys_isatty_p): Typo.
1769
1770 * list.h (scm_list_head): Missing prototype for function in
1771 list.c added.
1772
1773 * numbers.c (scm_two_doubles): Changed from extern to static
1774 (is used only within numbers.c).
1775
1776 * numbers.h: Repeated declarations removed.
1777
1778 * ports.h (scm_close_all_ports_except): Declaration for the
1779 function defined in ports.c added.
1780
1781 * posix.h: Missing declarations added.
1782

1784
1785 * socket.h (scm_sys_gethost): Missing declaration added.
1786
1787 * socket.h: Redundant declarations removed (they are in fdsocket.h).
1788
1789 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
1790 Missing declarations added.
1791
1792 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
1793
1794 * struct.c: Uninitialized variable `SCM answer' may be used.
1795
1796 * unif.c (l2ra): Declaration prototype.
1797
1798 * unif.c (scm_array_equal_p): Dummy definition removed (it is
1799 defined in ramap.c).
1800
1801 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
1802 Redundant declarations removed (they are in ramap.h).
1803
1804 * variable.h (scm_make_udvariable,
1805 scm_make_undefined_variable): Declaration corrected to
1806 correspond variable.c.
1807
1808 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
1809 Missing declarations added.
1810
1811 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
1812
1813 * Makefile.in (distclean): Don't forget to delete fd.h.
1814
1815 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1816
1817 * fd.h.in, tags.h: Trivial cleanups.
1818
1819 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
1820 marksweep.h just declared functions from gc.c.
1821 * gc.h, libguile.h: Don't #include "marksweep.h".
1822 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
1823 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
1824 dependencies updated.
1825
1826 * libguile.h: Don't #include "files.h"; it's been deleted.
1827
1828 * files.c (scm_sys_delete_file): Moved to filesys.c.
1829 File is now empty; deleted.
1830 * files.h: Deleted.
1831 * filesys.c: scm_sys_delete_file is now here. Remove
1832 #if's; they seem to rely on remnants of an old portability
1833 regimen. If the problems come up again, solve them properly,
1834 using autoconf. Specifically: Don't test M_SYSV, and #define
1835 remove to be unlink if it's #defined; don't use remove just
1836 because HAVE_STDC_HEADERS is #defined.
1837 * filesys.h: Add declarations for scm_sys_delete_file.
1838 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
1839 files.o, files.h, files.c, and files.x.
1840 * init.c: Don't #include "files.h", and don't call scm_init_files.
1841
1842 Use SCM_P instead of PROTO; the latter intrudes on the user's
1843 namespace.
1844 * params.h: Deleted; definition of SCM_P moved to...
1845 * __scm.h: ... here, where it replaces PROTO macro.
1846 * libguile.h, smob.h: Don't #include "params.h".
1847 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
1848 smob.h: Fix prototypes accordingly.
1849 * Makefile.in: Update dependencies.
1850 (inner_h_files): Remove params.h.
1851
1852 * gc.c: #include "gc.h"; every module should include its header,
1853 to let the compiler cross-check the declarations against the
1854 definitions.
1855
1856 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
1857 simpos.h: #include "libguile/__scm.h".
1858
1859 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
1860
1861 * init.c: Don't forget to #include smob.h and init.h.
1862 * Makefile.in: Dependencies updated.
1863
1864 * smob.h: Use PROTO instead of #if __STDC__.
1865
1866 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
1867
1868 * __scm.h: Doc fixes.
1869
1870 * __scm.h, libguile.h: Use "quotes" in the #includes, not
1871 <angles>; this allows `make depends' to work properly.
1872
1873 * libguile.h: #include smob.h and pairs.h before the others; they
1874 define typedefs used by other headers.
1875
1876 C files should #include only the header files they need, not
1877 libguile.h (which #includes all the header files); the pointless
1878 recompilation was wasting my time.
1879 * Makefile.in (all .o dependency lists): Regenerated.
1880 * libguile.h: Don't try to get a definition for size_t here...
1881 * __scm.h: Do it here.
1882 * _scm.h: Since this is the internal libguile header, put things
1883 here that all (or a majority) of the libguile files will want.
1884 Don't #include <libguile.h> here; that generates dependencies on
1885 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
1886 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
1887 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

1984 * weaks.c: Get "weaks.h".
1985
1986 * stackchk.h: #include "libguile/debug.h",
1987
1988 * print.h, read.h: #include "options.h", since everyone who uses
1989 either of these files will need that.
1990
1991 * smob.h: #include "ports.h", "genio.h", and "print.h", since
1992 anyone who uses this file will need them to define the smob
1993 printing functions. Also, get markers.h, since people will need
1994 to #define the mark functions.
1995
1996 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
1997 * ports.h: ... to here.
1998
1999 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2000 don't rely on archaic C default type rules.
2001
2002 * fports.h: #include "libguile/ports.h", since you need that in
2003 order to parse this.
2004
2005 * genio.h: #include "libguile/print.h", because you need that to
2006 parse this; don't bother #including "ports.h", since print.h gets
2007 that.
2008
2009 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2010
2011 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2012 this; it's now a reference to an element of *scm_root.
2013
2014 * debug.h: Don't #include "options.h"; the compiler won't be able
2015 to find that once the headers are installed; instead, #include
2016 "libguile/options.h".
2017 * gc.h: Same, with marksweep.h.
2018 * mbstrings.h: Same, with symbols.h.
2019 * scmhob.h: Same, with _scm.h.
2020 * smob.h: Same, with params.h.
2021
2022 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2023 C files; there's no need for this, and it forces recompilations
2024 unnecessarily.
2025
2026 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2027
2028 * error.c (scm_error): declare scm_error_callback.
2029
2030 * error.h: prototype for scm_error_callback.
2031
2032 * __scm.h: define lgh_error.
2033 (SCM_SYSERROR): redefine using lgh_error.
2034
2035 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2036
2037 * error.c (scm_error): new procedure.
2038
2039 * error.h: prototype for scm_error.
2040
2041 * Makefile.in (install): install scmconfig.h from the current
2042 directory, not $(srcdir).
2043
2044 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2045
2046 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2047 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2048 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
2049 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
2050 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
2051 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2052 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2053 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2054 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2055 vports.h, weaks.h: #include "libguile/__scm.h", not
2056 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2057 dependencies are within libguile properly.
2058
2059 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2060
2061 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2062 when scmconfig.h doesn't exist.
2063
2064 * load.c (scm_sys_try_load): Correct spelling.
2065
2066 * feature.c (scm_loc_features): Make this static.
2067
2068 * Makefile.in (libpath.h): Omit trailing slash from path. We
2069 shouldn't require it of users, so why put it here?
2070
2071 Move code to initialize and search %load-path from ice-9 to C
2072 code, so we can use the load-path to find the ice-9 boot code;
2073 this makes it easier to run Guile without installing it. See
2074 corresponding changes in guile/Makefile.in.
2075 * feature.c: Move stuff concerned with the load path to load.c.
2076 (scm_compiled_library_path): Deleted.
2077 Don't #include libpath.h here.
2078 * feature.h: Don't mention scm_compiled_library_path.
2079 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2080 <sys/stat.h>, and <unistd.h> (if present).
2081 (R_OK): #define if the system hasn't deigned to.
2082 (scm_loc_load_path): New variable.
2083 (scm_init_load_path, scm_sys_search_load_path,
2084 scm_sys_try_load_path): New functions.
2085 (scm_init_load): Initialize scm_loc_load_path to point to the
2086 value cell of the Scheme %load-path variable.
2087 * load.h: Add declarations for scm_sys_search_load_path,
2088 scm_sys_try_load_path.
2089 * init.c: Call scm_init_load_path.
2090 * Makefile.in (feature.o, load.o): Dependencies updated.
2091
2092 * load.c, load.h: Rewrite using PROTO macro.
2093
2094 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2095
2096 * gc.c (scm_cellp): New function: C predicate to determine if an
2097 SCM value can be regarded as a pointer to a cell on the heap.
2098
2099 * gc.h: Added declaration of scm_cellp.
2100
2101 * gdb_interface.h: New file: The GDB interface header from the GDB
2102 distribution.
2103
2104 * gdbint.c: New file: GDB interface.
2105
2106 * gdbint.h: New file: GDB interface.
2107
2108 * libguile.h: Added #include <libguile/gdbint.h>.
2109
2110 * init.c (scm_boot_guile): Added scm_init_gdbint.
2111
2112 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2113 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2114 found if object files and source are kept separate).
2115
2116 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2117
2118 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2119
2120 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2121
2122 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2123 TK_SRC_DIR; they're not relevant any more.
2124
2125 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2126 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2127
2128 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2129
2130 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2131 search path, so we can find the <libguile/MUMBLE.h> headers.
2132
2133 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2134
2135 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2136 implicit in the .c.o rule.
2137 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2138 $(CC) already.
2139
2140 Put the library path in a header file, instead of passing it on
2141 the command line in every compilation.
2142 * Makefile.in (libpath.h): New target.
2143 (feature.o): Depend on libpath.h.
2144 (clean): Delete libpath.h.
2145 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2146 * feature.c: ... #include "libpath.h" here.
2147 * .cvsignore: Ignore libpath.h.
2148
2149 Don't install the unwashed masses of Guile header files in the
2150 main #include path; put most of them in a subdirectory called
2151 'libguile'. This avoids naming conflicts between Guile header
2152 files and system header files (of which there were a few).
2153 * Makefile.in (pkgincludedir): Deleted.
2154 (innerincludedir): New variable; this and $(includedir) are enough.
2155 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
2156 (installed_h_files): Divide this up. Now this variable lists
2157 those header files which should go into $(includedir) (i.e. appear
2158 directly in the #include path), and ...
2159 (inner_h_files): ... this new variable says which files appear in
2160 a subdirectory, and are referred to as <libguile/mumble.h>.
2161 (h_files): List them both.
2162 (install): Create innerincludedir, not pkgincludedir. Put
2163 the installed_h_files and inner_h_files in their proper places.
2164 (uninstall): Corresponding changes.
2165 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2166 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2167 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
2168 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
2169 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
2170 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2171 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2172 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2173 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2174 vports.h, weaks.h: Find __scm.h in its new location.
2175 * __scm.h: Find scmconfig.h and tags.h in their new locations
2176 (they're both "inner" files).
2177
2178 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
2179
2180 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
2181
2182 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2183
2184 * posix.c: Doc fixes.
2185
2186 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
2187
2188 * socket.c: Don't include a prototype for inet_aton; just use a
2189 K&R style declaration, to avoid warnings but minimize the chance
2190 of conflicts with the system.
2191
2192 On NextStep, <utime.h> doesn't define struct utime, unless we
2193 #define _POSIX_SOURCE before #including it.
2194 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
2195 * acconfig.h: New comment text for above CPP symbol.
2196 * configure.in: Call it.
2197 * posix.c: #define _POSIX_SOURCE if it seems necessary.
2198
2199 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
2200 in the list.
2201 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
2202 testing for __EMX__.
2203
2204 * posix.c: #include <libc.h>, if it exists.
2205
2206 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
2207 don't even know if the latter exists.
2208
2209 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
2210 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
2211 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
2212
2213 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
2214 header files don't.
2215 (scm_init_posix): Use them when initializing the Scheme constants
2216 of the same name.
2217
2218 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2219
2220 * Makefile.in (libdir, includedir, bindir): Use the
2221 autoconf-supplied values, instead of deriving them ourselves.
2222 (pkgincludedir, datadir, pkgdatadir): New variables.
2223 (install, uninstall): Put the header files in a special
2224 subdirectory, not in the main search path.
2225
2226 * Makefile.in (ALL_CFLAGS): Provide the proper value for
2227 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
2228
2229 * Makefile.in (IMPLPATH): Deleted; never used.
2230
2231 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
2232 on the Tcl/Tk source any more.
2233 (INCLUDE_CFLAGS): Remove references to the above.
2234
2235 * Makefile.in (version.o): Corrected dependencies.
2236
2237 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
2238
2239 * libguile.h: #include "version.h"
2240
2241 * init.c (scm_boot_guile): Call scm_init_version.
2242 * gscm.c (gscm_run_scm): Call scm_init_version.
2243
2244 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
2245 GUILE_VERSION): AC_DEFINE these.
2246 (acconfig.h): #undef the above symbols.
2247
2248 * Makefile.in (libobjs): Add version.o.
2249 (installed_h_files): Add version.h.
2250 (c_files): Add version.c.
2251 (gen_c_files): Add version.x.
2252 (version.o): New rule.
2253 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
2254 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
2255 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
2256 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
2257 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
2258 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
2259 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
2260 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
2261 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
2262 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
2263 weaks.o): Add version.h to dependency lists.
2264 (markers.o): Remove duplicate rule.
2265
2266 * version.h: New file.
2267
2268 * version.c: New file.
2269
2270 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2271
2272 * symbols.c (scm_strhash): scm_downcase is now a function, not an
2273 array; use it appropriately. Since GCC is quite happy to
2274 subscript functions, it never warned us about this; we should use
2275 -Wpointer-arith in the future. I guess we never tested
2276 case-insensitivity.
2277
2278 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2279
2280 * socket.c: Doc and copyright fixes.
2281
2282 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2283
2284 * debug.c: Fixed and improved gdb support.
2285
2286 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2287
2288 * socket.c: Added declaration of inet_aton to avoid compiler
2289 warning. (Hope this solution is correct.)
2290
2291 * stime.c: Added declaration of ftime. (This is missing in
2292 Solaris 2 headers.)
2293
2294 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
2295
2296 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2297
2298 * Makefile.in (c_files): add strerror.c.
2299
2300 * strerror.c: new file from Emacs' sysdep.c.
2301 maybe configure should also check for sys_errlist.
2302
2303 * configure.in (AC_REPLACE_FUNCS): add strerror.
2304
2305 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2306
2307 * debug.c (scm_init_debug): Added initialization for
2308 scm_evaluator_traps.
2309
2310 * debug.h, debug.c: Various name changes.
2311 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
2312 "debug-options-interface". See commentary in options.c.
2313
2314 * options.h, options.c: Options now have documentation strings.
2315 Also added a long explanatory commentary.
2316
2317 * eval.c, print.h, print.c, read.h, read.c: Modifications to
2318 run-time options.
2319
2320 * gscm.c, init.c, root.c, throw.c: Bug fixes:
2321 last_debug_info_frame is now updated in all cases.
2322
2323 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
2324 checking.
2325
2326 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2327
2328 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
2329 Added option STACK_CHECKING.
2330
2331 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
2332
2333 * Makefile.in: Added {debug,options,srcprop}.{h,c}
2334
2335 * __scm.h: Removed symbols for debugging support.
2336
2337 * acconfig.h: Added symbols for debugging support.
2338
2339 * configure.in: Added user option for debugging support.
2340 --enable-debug will include the debugging code into libguile.a.
2341
2342 * continuations.c (scm_make_cont): Enlarged the #if 0 around
2343 scm_relocate_chunk_to_heap.
2344
2345 * debug.c: New file: low-level debugging support. It also
2346 includes support for debugging with gdb. (The extensions to gdb
2347 are written by Per Bothner at Cygnus.)
2348
2349 * debug.h: New file: low-level debugging support.
2350
2351 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
2352 argument pairs. Extensive modifications to the debugging
2353 evaluator. Added "SECTION:" commentaries to clarify what happens
2354 when, during double compilation. Renamed EVALIMP --> EVALIM.
2355 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
2356 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
2357 the beginning of the file. New procedure: scm_unmemocopy.
2358 Added some global state variables needed by the debugging
2359 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
2360 check_entry, check_apply, check_exit, debug_options and
2361 evaluator_traps. New acro: undefine.
2362
2363 * eval.h: Renamed EVAL --> XEVAL.
2364
2365 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
2366 --> scm_make_weak_key_hash_table.
2367
2368 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
2369 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
2370
2371 * libguile.h: Conditionally include debug.h
2372
2373 * objprop.c (scm_object_properties, scm_set_object_properties_x):
2374 scm_object_properties shouldn't return handle. `handle' now gets
2375 initialized in scm_set_object_properties_x. scm_object_properties
2376 doesn't any longer create an entry in scm_object_whash.
2377
2378 * options.c: New file: handling of run time options.
2379
2380 * options.h: New file: handling of run time options.
2381
2382 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
2383
2384 * print.c: New procedure: scm_print_options
2385
2386 * print.h: Defines for print options.
2387
2388 * read.c: New procedure: scm_read_options
2389
2390 * read.h: Defines for reader options.
2391
2392 * root.h: Added scm_source_whash among scm_sys_protects.
2393
2394 * srcprop.c: New file: source properties.
2395
2396 * srcprop.h: New file: source properties.
2397
2398 * throw.c (jbsmob): Jump buffers are now correctly allocated.
2399 (Bug found by A. Green.)
2400
2401 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2402
2403 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2404
2405 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
2406
2407 * libguile.h: #include "objprop.h"; I guess this was forgotten.
2408
2409 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
2410 and should be called by the final client.
2411
2412 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
2413
2414 * gc.h: Use the PROTO macro when declaring functions.
2415 * gc.c: Use the PROTO macro when declaring static functions.
2416 Remove the CPP hair around function definitions.
2417
2418 * gc.c (scm_init_storage): Initialize scm_asyncs.
2419
2420 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
2421 preprocessor symbol; "__scm.h" is where it might get #defined.
2422 * __scm.h: Similar: #include <scmconfig.h> before testing
2423 HAVE_LIMITS_H.
2424
2425 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
2426
2427 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
2428
2429 * init.c (scm_boot_guile): Add init_func argument; call
2430 (*init_func) instead of calling scm_appinit; it's ucky to
2431 hard-code names for the user's procedures.
2432 * init.h (scm_boot_guile): Adjust declaration.
2433
2434 * __scm.h (PROTO): New macro, for declaring functions with
2435 prototypes.
2436
2437 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
2438 eliminate all the __STDC__ conditionals.
2439 (scm_boot_guile): Add declaration.
2440 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
2441 Remove __STDC__ conditionals around function definitions; the
2442 declarations in init.h will provide the same information, more
2443 usefully.
2444
2445 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
2446 complain about it in the error message; the error message is
2447 adequate without that note, and there's nothing the user can do
2448 about it.
2449
2450 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
2451
2452 * Makefile.in (ancillary): Drop def.sed.
2453
2454 * posix.c (scm_init_posix): Use numeric values, rather than
2455 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
2456 F_OK. The symbols aren't available on some systems, and I'm
2457 pretty sure their values are fixed by common widespread practice.
2458 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
2459
2460 More functions unavailable on some systems.
2461 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
2462 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
2463 check for.
2464 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2465 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
2466 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
2467 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
2468 stub that signals an error as the #else.
2469
2470 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
2471
2472 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
2473
2474 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
2475
2476 * unif.c: include ramap.h.
2477
2478 * read.c (endif): case_insensative_p renamed case_insensitive_p.
2479
2480 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
2481
2482 * ports.c: include sys/ioctl.h.
2483
2484 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
2485
2486 * configure.in: check for sys/ioctl.h.
2487
2488 * ports.c: include <malloc.h> not "malloc.h".
2489
2490 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2491
2492 * fports.c: remove ttyname and tmpnam declarations.
2493
2494 * posix.c: fewer ttyname declarations.
2495
2496 * fports.c: include <string.h> not "string.h".
2497
2498 * init.c, ioext.c: include string.h and unistd.h.
2499
2500 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2501
2502 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
2503 genio.c, simpos.c, vports.c: include string.h.
2504
2505 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
2506
2507 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
2508 scm_sizet to int.
2509 (scm_addr_buffer_size): change type from scm_sizet to int.
2510 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
2511 from scm_sizet to int.
2512
2513 * error.c: include unistd.h.
2514
2515 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
2516 defined.
2517
2518 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
2519
2520 * __scm.hd, def.sed: deleted.
2521
2522 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
2523
2524 Changes for NeXT, suggested by Robert Brown.
2525 * configure.in: Call AC_TYPE_MODE_T.
2526 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
2527 NeXT. Put header file list in alphabetical order.
2528 * configure, scmconfig.h.in: Regenerated.
2529 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
2530
2531 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
2532 for strerror.
2533
2534 * acconfig.h: New file, providing documentation for the CPP
2535 symbols defined in configure.in
2536 * acconfig-1.5.h: Removed; superceded by the above.
2537

2560
2561 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
2562 This is necessary on Ultrix, and doesn't hurt portability.

2565 (installed_h_files): Put in alphabetical order.

2572 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
2573
2574 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:

2576 non-zero exit code whenever the if's condition is false.

2588 Remove leading % from scheme names.

2609
2610 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
2611 weak hash tables last of all marking to avoid an obscure gc bug.

2641
2642 * ports.c (scm_ports_prehistory): size malloced here doesn't
2643 matter so long as it is non-0 (got rid of "* 4").
2644
2645 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
2646
2647 * gscm.h: gscm_mkarray eliminated (presumably was not being used

2664
2665 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
2666 handled correctly (SCM_FREEP was applied to them) -- test for
2667 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
2668 being overwritten with #f. (brown@grettir.bibliotech.com)

2715 * pairs.c (scm_delq_x): never throw an error.
2716
2717 * vectors.c (scm_make_vector): made the default vector fill argument
2718 into '() (much more useful than the previous value, "#unspecified")
2719
2720 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
2721
2722 * ports.c (scm_add_to_port_table): Added fields

2742
2743 * gc.c (scm_gc_end): simulate a signal at the end of each GC.

2823 functions. hash, hashq, hashv, hashx.
2824
2825 * tags.h: made wvect an option bit of vector.
2826

2861 set the multi_byte flag correctly in symbols. This is wrong.
2862 intern_obbary_soft and msymbolize should take an extra parameter.

2864 The weird symbol syntax is also a bit bogus (emacs doesn't quite
2865 cope).
