1 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
8 from pairs with a GLOC in the car.
10 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
11 otherwise `symbol-hash' will behave badly.
12 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
13 we get segmentation fault!
15 * symbols.c: Added #include "weaks.h". New functions
16 `builtin-bindings' and `builtin-weak-bindings'. (These will be
17 moved to an extraneous library when we split libguile.)
19 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
21 * filesys.c (scm_stat): stat now takes fport arguments too as
22 documented in the manual.
24 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
26 * debug.c (scm_single_step): Bugfix: Call continuation with
27 scm_call_continuation instead of throwing to it.
29 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
31 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
32 argument wasn't declared to be optional.
34 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
36 * stime.c (scm_init_stime): Add feature "current-time".
38 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
40 * throw.h: prototype for scm_exit_status.
41 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
42 args to derive an exit status. Allows (quit) to work from a
44 (scm_exit_status): new function.
47 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
49 * eval.c (scm_deval): Removed some old code.
50 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
52 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
55 * symbols.c (msymbolize): Bugfix: Must initialize property list to
58 * procs.c: Introduce the existent C function scm_thunk_p at the
61 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
63 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
64 used from C to easily lookup the value of a symbol in the current
67 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
69 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
70 scm_init_unif in this file. This will also fix a previous problem
73 * configure.in: Added AM_MAINTAINER_MODE
75 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
77 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
80 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
82 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
83 source files that are not always included in libguile but should
84 have their dependencies calculated by automake. This variable is
85 recognized by automake, no further magic is needed.
86 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
87 to deal exclusively with *.lo files, as it seems. The *.o files
88 are built automatically when the corresponding *.lo file gets
91 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
93 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
96 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
98 * unif.c (scm_array_set_x): minor change to argument error checking.
100 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
102 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
103 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
104 They should only be included in the library at configure.in's
106 (libguile_la_LDADD): Include the appropriate .lo files here.
107 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
108 so we know when to build them (and their .lo bretheren).
109 * configure.in (LIBLOBJS): New substituted variable. We let
110 configure decide which .o files to include in LIBOBJS, and then
111 put the corresponding list of .lo files in LIBLOBJS. The latter
112 is what we pass to libtool.
113 * Makefile.in, configure: regenerated.
115 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
117 * symbols.c (scm_sysintern0): New function. Contains the core of
118 old scm_sysintern but doesn't take a second value argument.
119 (scm_sysintern): Now uses scm_sysintern0.
120 (scm_sysintern_no_module_lookup): Renamed to
121 scm_sysintern0_no_module_lookup and doesn't take a second value
124 * symbols.h (scm_sysintern0: Added declaration.
126 * options.c (scm_init_opts): Use scm_sysintern0 instead of
127 scm_sysintern when interning option keys. Otherwise we risk
128 destroying the values of already interned variables.
130 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
131 scheme-level boolean (use SCM_NFALSEP).
133 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
135 (scm_backtrace): New function. (C version of old function from
136 boot-9.scm) Motivation: Make it possible to display backtraces
137 without depending on boot-9.scm. (I'm uncertain if this
138 motivation is good enough...)
140 * root.h (scm_root_state): Add member the_last_stack_var.
141 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
143 * root.c (mark_root): Mark scm_the_last_stack_var.
145 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
148 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
150 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
151 1. mark_lazy_catch didn't mark the smob.
152 2. Both functions above have standard variants:
153 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
154 free_lazy_catch --> scm_free0.
156 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
158 * throw.c (scm_internal_lazy_catch): New function.
159 (scm_lazy_catch): Rewritten to use it.
160 (scm_ithrow): Handle the new lazy catch representation.
161 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
162 that doesn't have a jmpbuf is a lazy catch clause.
163 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
164 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
165 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
167 (scm_init_throw): Register the new lazy-catch smob type.
168 * throw.h (scm_internal_lazy_catch): decl for new function.
170 * throw.c (scm_internal_catch): Doc fixes.
172 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
173 configure.in. Including this might cause problems if applications
174 that link against libguile include their own copies of alloca, but
175 if they're using autoconf, they should be adding libguile to LIBS
176 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
177 the copy in libguile, and things will be okay. (I think.)
179 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
181 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
183 strop.h: move prototypes too.
185 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
187 * posix.c (scm_init_posix): don't intern EINTR since it's now done
190 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
191 etc. I deleted them from filesys.c long ago, but didn't
192 notice they were here too (although ineffective since
193 sys/stat.h wasn't included).
195 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
197 * eval.c: Don't define alloca in GCC case. gcc will automatically
198 use __builtin_alloca if appropriate.
200 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
202 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
203 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
204 that values of automatic variables are preserved. See comments
205 for safe_setjmp for details.
207 Change from Thomas Morgan:
208 * variable.c: Include eq.h.
209 (var_equal): New function.
210 (variable_smob): Use var_equal as the discriminator for variables.
212 * throw.c (s_throw): Remove extraneous declaration.
214 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
215 * eval.c: Add necessary CPP cruft to support that.
216 * configure, Makefile.in, scmconfig.h.in: regenerated.
218 Change from Thomas Morgan:
219 * procprop.c (scm_procedure_properties): Convert the Scheme
220 boolean returned by scm_procedure_p into a C boolean before using
221 it as a condition for SCM_ASSERT.
222 (scm_procedure_property): Likewise.
224 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
225 indications of Unixness.
228 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
230 * * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
232 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
234 * read.c (scm_lreadr): use scm_misc_error to improve one of the
235 "unknown # object" error messages.
237 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
238 (scm_i_index) and declare it static. Add a 'direction' argument
239 to indicate what way the search should go.
240 (scm_i_index): throw out-of-range error instead of wrong-type-arg
242 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
243 strop.h: remove scm_i_index, scm_i_rindex prototypes.
245 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
247 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
249 * * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
250 to avoid clash with various scsh forks.
252 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
254 The following two changes (ramap.c, throw.c) are motivated by the
255 apparent unportability of forward declarations of static arrays of
256 the form `static foo bar[];'.
258 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
259 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
261 * throw.c (scm_throw): Moved above scm_ithrow.
263 * options.h: Removed the extern declarations of scm_yes_sym and
264 scm_no_sym since these are static.
266 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
268 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
270 * Makefile.am: remove AWK=@AWK@.
271 Add a rule for generating errnos.list.
272 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
274 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
275 don't extract errnos, just set a variable (avoids the
276 need to recompile error.c just because configure is run.)
278 * unif.h: update prototypes.
279 * unif.c (scm_uniform_array_read,write): change the offset and
280 length arguments to start and end, for consistency.
282 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
284 * ioext.h: update prototypes.
285 * * ioext.c (scm_read_delimited_x): replaces scm_read_line and
286 scm_read_line_x, it's a more general procedure using an
287 interface from scsh. read-line and read-line! are now defined
289 * Note that the new read-line trims the terminator
290 by default, previously it was appended to the returned string. An
291 optional argument specifies how to process the terminator (scsh
292 compatible). For the old behaviour: (read-line port 'concat).
293 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
294 returns a pair, but is converted to multiple values if the scsh
297 socket.h: update prototypes.
298 * socket.c (scm_recvfrom): for consistency with other procedures,
299 take start and end as separate optional arguments.
300 * (scm_recv, scm_recvfrom): don't allow the second argument
301 to be a size, only a buffer. Change the scheme names to
302 recv! and recvfrom!. Don't return the buffer.
304 * ioext.h, posix.h: move prototypes too.
305 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
306 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
307 "read.h" and "unif.h".
308 * ioext.c: include "chars.h"
310 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
312 * dynl.c: The dynamic linking and module registration functions
313 are now defined even when dynamic linking is not available for the
314 host system. Some of their functionality can be done without
315 dynamic linking; when it's really needed, they throw errors.
317 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
319 * configure.in: Only define DYNAMIC_LINKING when one of the system
320 dependent functions is detected.
321 * dynl.c (scm_dynamic_func): New function to get the address of a
322 function in a dynamic object.
323 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
324 produced by scm_dynamic_func as the thing to call.
326 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
328 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
329 (scm_register_module_xxx, scm_registered_modules,
330 scm_clear_registered_modules): New functions.
332 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
334 * symbols.c (scm_sysintern): Renamed to
335 scm_sysintern_no_module_lookup.
336 (scm_sysintern): New function to take the place of the old
337 scm_sysintern. It uses the current toplevel lookup closure to give
338 the symbol its value. This is a temporary hack to put packages
339 like gtcltk into their own module.
340 (scm_can_use_top_level_lookup_closure_var): New variable to tell
341 us whether `scm_top_level_lookup_closure_var' has been initialized
343 * eval.c (scm_init_eval): Set it.
345 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
347 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
348 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
350 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
352 * (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
353 scm_sys_dup): deleted: FD capability will be added to other
355 * Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
356 scm_fd_free, fd_smob, scm_intern_fd.
357 * (scm_open): renamed from scm_sys_open. Return a port instead of
358 an FD object. Make the mode argument optional.
359 * (scm_sys_create): deleted, it's just a special case of open.
360 (scm_init_filesys): move interning of constants O_CREAT etc.,
361 here (were previously using SCM_CONST_LONG macro).
362 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
364 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
365 include "fports.h" and <stdio.h>
366 (scm_stat, scm_select): don't support FD objects.
368 * error.h: adjust scm_syserror_msg prototype.
369 * error.c (scm_syserror_msg): take an extra argument for errno.
370 Using the global value didn't always work, since it could be
371 reset by procedure calls in the message or args arguments.
373 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
374 I don't understand why the check was there (and what about the
377 * strop.c (scm_string_copy): allow shared substrings to be copied.
379 * unif.h: corresponding change to prototypes.
380 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
381 recognize two new optional arguments: offset and length. Allow
382 the port argument to be an integer (file descriptor, for scsh).
383 Include <unistd.h> for "read" prototype.
385 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
387 * socket.c: don't include filesys.h.
389 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
391 * Makefile.am: add AWK=@AWK@ (?)
393 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
395 Add a rule to generate errnos.c from errnos.
396 * error.c (scm_init_error): include errnos.c.
397 * errnos_cnvt.awk: new file, converts the list of errno codes to
399 * errnos_get.c: new file.
400 * errnos.default: new file, contains errnos to try if they can't
401 be extracted from errno.h.
402 * configure.in: if using GCC, try and extract errno codes from
406 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
408 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
409 * Makefile.am: Made libguile into a libtool library.
410 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
411 Set libtool_libs to indicate that libguile is a libtool library.
412 See guile/ChangeLog for details.
413 * .cvsignore: ignore "*.lo", the libtool library objects.
415 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
417 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
418 use htons in getservbyport argument.
420 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
422 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
423 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
426 * objprop.c (scm_object_property): No need to take the CDR of the
427 value returned by scm_object_properties, since Aug 20 change.
429 * configure.in: When checking for struct linger, #include
430 <sys/types.h> as well as <sys/socket.h>. I've never known
431 <sys/types.h> to cause any portability problems, and Solaris's
432 <sys/socket.h> needs it.
433 * configure: Rebuilt.
435 I think the Sun compiler has chosen a perverse way to interpret
436 ANSI declarations combined with K&R definitions. We'll
437 appease it a little bit. But when it invades France, we fight.
438 * print.c (scm_iprlist): Change 'tlr' argument to an int.
439 * print.h (scm_iprlist): Here too.
440 * numbers.c (scm_divbigdig): Change definition to match
441 declaration in numbers.h.
442 * unif.c (scm_makflo): Change definition to match declaration in
445 * init.c (scm_boot_guile): Don't return the value of
446 scm_boot_guile_1. This function doesn't return a value;
447 scm_boot_guile_1 doesn't return a value (or return at all).
449 * eval.c (unmemocopy): Add a semicolon to appease the Sun
452 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
453 compile. I have a feeling this function is a bad idea anyway ---
454 one should always test for features, not systems.
456 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
457 semicolons. Only pure luck kept this from being noticed earlier.
459 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
461 * socket.c (scm_recvfrom): Added missing semicolon.
463 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
465 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
466 the buffer and start and end positions for scsh networking
469 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
471 * configure.in: Revert previous change to this file; the problem
472 is due to transient automake weirdness.
473 * configure: Rebuilt.
475 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
476 PLUGIN/guile.libs. configure generates the latter from the former.
477 * Makefile.in: Rebuilt.
479 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
480 need this if we install scripts, like guile-snarf.
481 * configure: Rebuilt.
483 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
485 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
487 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
489 * socket.c (scm_addr_vector): fix faulty scm_listify.
491 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
493 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
494 style block comment is no longer considered an error.
496 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
498 * PLUGIN/guile.libs.in: New file.
499 * PLUGIN/guile.libs: Removed from repository.
500 * configure.in: Create PLUGIN/guile.libs from
501 PLUGIN/guile.libs.in. This is for including additonal libraries
502 needed for dynamic linking.
503 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
504 instead of PLUGIN/guile.libs.
506 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
508 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
510 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
511 occurrences of the given element from the list, not just the
512 first. This is how the Emacs Lisp functions behave, how the
513 analogous Common Lisp functions behave, and (I believe) how the
514 older Maclisp functions worked. I realize that this change may
515 break code, but it seemed better to break it before the Guile
518 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
519 Their prototypes were already present in gc.h, but they weren't
521 (scm_init_storage): Initialize scm_protects.
522 * root.c (scm_protects): New element of scm_sys_protects.
524 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
526 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
528 * libguile.h: Added #include "libguile/net_db.h".
530 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
531 30 change. That file is only meant for communication between the
532 configuration process and load.c. If code linked against libguile
533 wants to get at the paths mentioned in libpath.h, it can call
534 functions declared in load.h.
536 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
538 * libguile.h: Removed #include "libguile/fdsocket.h"
540 * net_db.c: Added #include <sys/socket.h>.
542 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
544 * filesys.c (scm_input_waiting_p): use select in preference to
545 FIONREAD, since the latter doesn't detect EOF.
546 Throw error if neither select nor FIONREAD available.
548 * socket.c (scm_connect): take a port, not a fd object.
549 (scm_fill_sockaddr): throw an error if fam is not recognised.
550 (scm_bind): use scm_fill_sockaddr.
551 (scm_listen): take a port, not a fd object.
552 (scm_accept): take and return a port. return #f in the car if
554 (scm_sock_fd_to_port): new procedure.
555 (scm_socket): use scm_sock_fd_to_port.
556 (scm_addr_vector): throw error if unrecognised address type.
557 take an extra argument with the calling procedure name.
558 (scm_getsockname): take a port. return #f if address can't be got.
559 (scm_getpeername): take a port. return #f if address can't be got.
560 (scm_recvfrom): take a port. return #f for address component if can't
562 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
563 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
565 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
567 * throw.c (scm_internal_catch): Make body funcs and handler funcs
568 use separate data pointers, to allow them to be designed
569 independently and reused.
570 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
571 Renamed from catch_body, catch_handler, and uncaught_throw; made
573 (struct scm_catch_body_data): Renamed from catch_body_data; moved
575 (scm_catch): Use the above.
576 (scm_throw): Don't bother printing a message for an uncaught
577 throw; we establish a default handler in init.
578 * throw.h (scm_internal_catch): Prototype updated.
579 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
581 (struct scm_body_thunk_data): New structure, used as data
582 argument to scm_body_thunk.
583 * init.c (struct main_func_closure): New structure, packaging up
584 the data to pass to the user's main function.
585 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
586 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
587 scm_internal_catch to establish a catch-all handler, using
588 scm_handle_by_message. This replaces the special-case code in
590 (invoke_main_func): Body function for scm_internal_catch; invoke
591 the user's main function, using the main_func_closure pointer to
592 decide what to pass it.
593 * root.c (struct cwdr_body_data): Remove handler_proc member.
594 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
595 (cwdr_handler): Removed.
597 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
599 * socket.h (SCM_P): update bind prototype.
600 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
602 (scm_socket): return a port, not a file descriptor object.
603 include "fports.h" and <unistd.h>
604 (scm_bind): take a port, not a file descriptor object.
605 take an extra argument for address args.
607 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
608 INADDR_NONE, INADDR_LOOPBACK.
610 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
612 * init.c: include net_db.h and not fdsocket.h.
613 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
615 * Makefile.am: corresponding changes.
616 * socket.h: renamed from fdsocket.h, fix names.
617 * net_db.h: renamed from socket.h, fix names.
618 * socket.c: renamed from fdsocket.c.
619 remove _sys from procedure names.
620 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
621 add "socket" to features list.
622 * net_db.c: renamed from socket.c.
623 remove _sys from procedure names.
624 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
625 add "net-db" to features list.
626 include "net_db.h". don't include <sys/socket.h> or
629 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
631 * tags.h (scm_tags): Removed comma at end of last enumerator.
633 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
635 Don't use GCC extensions to allocate space for debugging frames.
636 (Here he goes again! Why do we put up with this?!)
637 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
638 an scm_debug_info structure, not an in-line array of them. Add
639 'info' member, to say how many vect elements we've used, for eval
641 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
642 a new variable debug_info_end to mark the end of vect, instead of
643 the address of the 'info' pointer itself.
644 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
645 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
646 (SCM_APPLY): Explicitly allocate space for debug.vect.
647 * debug.c (scm_m_start_stack): Same, for vframe.vect.
648 * stacks.c: Adjusted for new debug frame structure.
649 (RELOC_INFO, RELOC_FRAME): New macros.
650 (stack_depth, read_frames): Use them, and new scm_debug_frame
651 element 'info', instead of magically knowing that eval frames have
652 an info pointer sitting after vect.
653 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
655 (scm_init_stacks): Formatting tweaks.
657 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
659 Give GCC more control flow information, so it can be sure that
660 variables aren't used uninitialized.
661 * error.h (scm_error, scm_syserror, scm_syserror_msg,
662 scm_sysmissing, scm_num_overflow, scm_out_of_range,
663 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
664 scm_misc_error): Tell GCC that these functions never return.
665 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
666 out the field type, call abort if SCM_ASSERT returns, to placate
668 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
669 scm_wta ever returns. We can't handle this case anyway, and this
670 gives the optimizer more information.
671 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
672 scm_wta ever returns.
674 In some cases, the code is fine, but GCC isn't smart enough to
675 figure that out; this usually happens when one variable is only
676 initialized and used when a particular condition holds true, and
677 we know that condition will never change within a given invocation
678 of the function. In this case, we simply initialize the variables
679 to placate the compiler, hopefully to a value which will cause a
680 crash if it is ever actually used.
681 * print.c (scm_iprin1): Initialize mw_pos.
682 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
683 * throw.c (scm_ithrow): Initialize dynpair.
684 * unif.c (scm_uniform_vector_ref): Initialize cra.
685 * struct.c (init_struct): Initialize prot.
686 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
688 * strports.c (scm_eval_0str): Don't return uninitialized garbage
689 if EXPR contains no expressions.
691 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
693 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
694 cause an infinite loop (???). So much for the algebraic
695 equivalency of variable-sized arrays and alloca...
697 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
699 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
700 a SCM boolean, not a C boolean.
702 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
704 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
705 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
706 rules for raising scm_mtrigger. Previously, unfortunate but not
707 unlikely circumstances could result in almost constant invokation
708 of the gc. Now, this situations should be less likely, but they
709 are not prevented completely.
711 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
713 * numbers.c (scm_fuck): Procedure removed; looks like old test
715 * numbers.h: Prototype removed.
717 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
719 * debug.h (scm_debug_frame): Change `vect' member from an in-line
720 array to a pointer, to match my Nov 21 change in eval.c.
722 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
724 * libguile.h: Added #include "libguile/backtrace.h", #include
727 * strings.c (scm_string scm_make_string scm_string_ref
728 scm_string_set_x scm_string_equal_p scm_string_append):
729 Bugfix according to scm patch from Aubrey Jaffer:
730 Corrected long-standing
731 (not (eqv? (integer->char 128)
732 (string-ref (make-string 1 (integer->char 128)) 0)))
733 bug found by John Kozak <jk@noontide.demon.co.uk>.
735 * strports.c, strports.h: Make scm_eval_0str return the value of
736 the last expression evaluated (previously, it returned void).
738 * strports.c, strports.h: New function: scm_read_0str. Does what
741 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
743 * simpos.c (scm_getenv): return #f if string can't be found in the
744 environment instead of throwing an exception, for compatibility
745 with numerous other systems.
747 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
749 * Makefile.am (.c.x): Use guile-snarf.
750 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
752 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
754 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
756 * backtrace.c (scm_display_error_message): Made non-static, and
757 renamed from display_error_message.
758 * backtrace.h (scm_display_error_message): Added extern decl.
759 * throw.c (uncaught_throw): Use it to display the error message.
761 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
763 * inet_aton.c: Use #if 0, not #ifdef 0.
765 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
767 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
768 to convert the returned value.
769 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
772 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
774 Add new interface to catch/throw, usable from C as well as
776 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
777 (scm_internal_catch): New function, replaces...
778 (scm_catch_apply): Deleted.
779 * throw.c (scm_catch_apply): Deleted; replaced with a more general
780 mechanism which is a bit more code, but can be used nicely from C
781 and implement the Scheme semantics as well.
782 (scm_internal_catch): This is the replacement; it's named after
783 the analogous function in Emacs.
784 (scm_catch): Reimplemented in terms of the above.
785 (struct catch_body_data, catch_body, catch_handler): New
786 functions, used by scm_catch.
787 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
788 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
789 support for new cwdr.
791 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
794 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
796 * acconfig.h: Added DYNAMIC_LINKING symbol.
797 * configure.in: Add option and checks for dynamic linking.
798 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
799 dynl.h: New files for dynamic linking support.
800 * Makefile.am (libguile_a_SOURCES):
802 (modinclude_HEADERS): Added "dynl.h".
803 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
805 * init.c (scm_boot_guile_1): Call
806 scm_init_dynamic_linking to initialize dynamic linking support.
808 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
810 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
811 (as we Schemers say). It needs to be global, so that I can tweak
812 it for the proper operation of unexec.
813 (scm_boot_guile_1_live): New variable, see above.
815 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
817 * guile-snarf.sh: Removed.
818 * PLUGIN/guile.libs: Added dependency for -lm.
819 * acinclude.m4: Renamed from aclocal.m4.
820 * PLUGIN/greet: Removed.
821 * Makefile.am, aclocal.m4: New files.
822 * configure.in: Updated for Automake.
824 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
826 * eval.c (scm_definedp): Use top_level_lookup_closure_var
827 and not top_level_lookup_thunk_var.
829 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
831 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
833 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
835 * eval.c (scm_definedp): Incompatibly changed to be a builtin
836 Scheme function, instead of syntax. Single argument is now a
839 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
841 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
842 scm_ra_divide): Properly terminate statements passed as arguments
843 to IVDEP macros. (Thanks to Bernard Urban.)
845 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
846 with non-constant sizes. (Thanks to Bernard Urban.)
848 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
850 It's an "eval closure", not an "eval thunk." A thunk is a
851 function of no arguments.
852 * root.h (struct scm_root_state): Renamed
853 top_level_lookup_closure_var from top_level_lookup_thunk_var.
854 (scm_top_level_lookup_closure_var): Renamed from
855 scm_top_level_lookup_thunk_var.
856 * root.c (mark_root): Uses changed.
857 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
858 * init.c (scm_start_stack): Uses changed.
859 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
860 Change scheme-visible name to *top-level-lookup-closure* from
861 *top-level-lookup-thunk*.
863 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
865 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
866 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
868 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
870 * gc.c (struct scm_heap_seg_data): Doc fixes.
872 * gc.c (scm_gc_sweep): Empty all segments' freelists before
873 sweeping. Then, prepend each segment's free cells to its
874 freelist, rather than wiping out the old value. (Thanks to Marius
877 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
878 scm_check_freelist, scm_debug_newcell): New functions and
879 variables, for debugging freelist problems.
880 * pairs.h (SCM_NEWCELL): New debugging version added.
881 * gc.h (scm_debug_newcell): Added extern declaration, used by
882 debugging version of SCM_NEWCELL.
884 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
886 On some systems <libc.h> conflicts with <unistd.h>, and should not
888 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
889 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
890 * configure.in: Call it.
891 * posix.c, filesys.c: Use its results to decide whether or not to
893 * configure, scmconfig.h.in: Rebuilt with autoconf and
896 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
898 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
899 pointer to the stdio stream before calling scm_setbuf0, so the
900 latter will be able to retrieve it. I'm surprised this didn't
901 segfault earlier. (Thanks to Christopher Lee.)
903 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
905 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
908 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
910 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
911 number of stack narrowing specifier pairs. The first specifier in
912 a pair controls inner border, the second the outer border. A
913 number means cut that number of frames, a procedure object means
914 cut until that object is found in operator position in a frame.
916 * root.c (cwdr): Bugfix.
918 * read.c: Recording of positions disabled by default.
920 * procs.c (scm_closure_p): New function.
922 * posix.c (scm_tmpnam): New function.
924 * load.c: Added #include "throw.h".
925 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
928 * load.c, load.h (scm_read_and_eval_x): New function.
930 * eval.c: Renamed debug option "deval" to "debug".
932 (scm_eval_x): `eval!' is no longer accessible from the scheme
933 level. Motivation: We can't allow operations which introduce
934 glocs into the scheme level. Guile's type system can't handle
935 these as data. Use `eval' or `read-and-eval!' as replacement.
937 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
938 SCM_CONSP since this is a macro!; Set vframe.prev to
939 scm_last_debug_frame instead of 0. In this way we can look
940 "above" the virtual start stack frame if we wish.
941 (scm_debug_hang): New function: Useful for debugging Guile in
942 certain tricky situations. Will probably be removed later...
944 * debug.h: Changed semantics of debug option "backtrace". This
945 option now only indicates whether we want automatic backtrace at
948 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
950 * ports.c: #include "filesys.h"
951 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
953 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
954 Motivation: This is system specific code which is related to file
955 I/O. It also may use select. Added code by Gary Houston to
956 detect presence of character in stdio buffers.
958 * libguile.h: #include "libguile/libpath.h"
960 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
961 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
962 SCM_SITE_DIR; Install libpath.h among the other include files.
964 * load.c, load.h (scm_sys_package_data_dir): New function.
966 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
968 * stacks.h: Bugfix: Don't use tail-array length field as stack
969 length field! This screwed GC.
971 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
973 * _scm.h: Added #ifndef around definition of macros min and max.
975 * __scm.h: Added hooks for threads to plugin to in ints protection
976 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
977 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
978 the main code in these macros duplicated and spread over multiple
979 files. Renamed SCM_THREADS_SWITCHING_CODE ->
980 SCM_THREAD_SWITCHING_CODE.
982 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
985 * guile-snarf.sh: New file.
986 * Makefile.in (inner_h_files): Added snarf.h
987 (ancillary, install, uninstall, distclean): Added actions for
989 (.c.x): Use guile-snarf.
990 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
991 (gen_c_files): Note that these depend on guile-snarf.
992 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
993 now in "snarf.h". Added #include "snarf.h" to get them.
994 * libguile.h: Added #include "snarf.h".
995 (Patches applied and tweaked by Jim Blandy.)
997 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
999 * socket.c: Use K&R style declaration for 'close'; the GNU coding
1000 standards suggest against providing prototypes for system
1001 functions. Thanks to Greg Troxel.
1003 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1005 * strports.c (scm_eval_0str): New function.
1006 #include "read.h", to get prototype for scm_read.
1007 * Makefile.in (strports.o): Update dependencies.
1008 * strports.h: New prototype.
1010 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
1011 scheme name from "int?" to "integer?". It seems to do the job.
1012 * numbers.h: Rename prototype too.
1013 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
1016 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
1017 scm_num_eq_p): Rename these according to R4RS conventions: call
1018 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
1019 to making libguile R4RS compliant without ice-9...
1021 * load.c (scm_sys_search_load_path): Search for files under all
1022 extensions listed in the %load-extensions variable. If FILENAME
1023 is absolute, return it unchanged, without searching the load path.
1024 (scm_loc_load_extensions): New variable, pointing to
1025 %load-extensions' value cell.
1026 (scm_init_load): Initialize it, and the value it points to.
1027 (scm_primitive_load_path): Improve error reporting.
1029 * load.c (scm_loc_load_hook): New variable, pointing to value cell
1030 of new Scheme variable %load-hook.
1031 (scm_primitive_load): Apply %load-hook to filename.
1033 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
1035 * configure.in: add tests for figuring out whether buffered data
1036 is available in a FILE structure, which is needed by char-ready.
1038 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
1041 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
1042 exceptions using misc_error instead of syserror. It seems a bit
1043 odd to throw an exception if a string can't be found in the
1044 environment, but it's consistent with open-file, stat etc.
1045 (simpos.h): remove sys_ from getenv.
1047 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
1048 occurs, throw an error instead of returning errno. Return value
1050 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1052 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1054 * filesys.c (scm_stat2scm): derive file type and permissions from
1055 the stat mode and append them to the returned vector.
1056 There isn't much overhead in doing this and it avoids the need to
1057 work with S_IRUSR et al. in Scheme.
1058 Define symbols scm_sym_regular etc.
1059 (scm_init_filesys): don't intern S_IRUSR etc.
1061 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1062 and s_primitive_load_path.
1064 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1066 * error.h: don't declare error symbols. prototype for scm_misc_error.
1068 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1071 * error.c: use SCM_SYMBOL to set up error keys.
1072 scm_misc_error: new procedure.
1074 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1076 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1077 between `#!' and `!#' is ignored.
1078 (skip_scsh_block_comment): New function.
1080 * feature.c (scm_set_program_arguments): New argument, FIRST.
1081 * feature.h: Update prototype.
1082 * init.c (scm_boot_guile_1): Pass new argument to
1083 scm_set_program_arguments.
1085 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1087 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1088 (scm_boot_guile): Call scm_set_program_arguments here, later than
1089 the old initialization.
1091 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1092 initialization procedure.
1093 - Delete in, out, err arguments; there are other perfectly good
1094 ways to override these when desired.
1095 - Delete result argument; this function shouldn't ever return.
1096 - Rename init_func argument to main_func, for less confusion.
1097 - Delete boot_cmd argument; main_func is more general.
1098 -Add 'closure' argument, to help people pass data to main_func
1099 without resorting to global variables.
1100 - Abort if reentered; don't bother returning an error code.
1101 - Call scm_init_standard_ports to set up the default/current
1102 standard ports; no need to pass them to scm_start_stack.
1103 - Remove code to evaluate the boot_cmd, and start the repl; let
1104 the user do something like that in main_func if they want.
1105 - Remove code to package up a return value; main_func can do any
1107 - Call exit (0), instead of returning.
1108 (scm_start_stack): Don't initialize the I/O ports here; that's
1109 weird. Delete in, out, err arguments. Move guts to
1110 scm_init_standard_ports, scm_stdio_to_port.
1111 (scm_init_standard_ports): New function, to set up current and
1112 default standard ports.
1113 (scm_start_stack, scm_restart_stack): Make these static.
1114 * init.h (scm_boot_guile): Adjust declaration.
1115 (scm_start_stack, scm_restart_stack): Remove externally
1116 visible declarations for these.
1117 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1119 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1120 written out several times in scm_start_stack.
1121 * fports.h: New declaration for the above.
1123 * feature.c (scm_set_program_arguments): New function.
1124 * feature.h: New declaration for the above.
1126 * ports.c: Formatting tweak.
1128 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1130 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1131 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1132 for obtaining the address of a car or cdr field. Motivation:
1133 &SCM_CXR make assumptions about the internal structure of the
1136 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1137 Motivation: see SCM_CXRLOC.
1139 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1140 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1141 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1142 Motivation: Safer use. Some other macros are defined in terms of
1143 these operations. If these are defined using the SCM_SETCXR
1144 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1145 to inefficiency and an <e1> with side-effects could potentially
1146 break. Also, these particular operations are heavily utilized in
1147 the garbage collector. In unoptimized code there will be a
1150 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1151 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
1152 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
1153 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
1154 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
1155 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1156 vports.c: Cleaned up use of pairs: Don't make any special
1157 assumptions about the internal structure of selectors and
1158 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1159 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1160 (Among other things, this change makes it easier to build Guile
1161 with certain compilers which have problems with casted lvalues.)
1163 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1165 * stacks.c: Improve selection of relevant stack frames when making
1166 a stack object. Introduce one level of indirection in the stack
1167 object to make it possible to "narrow" to a certain region of the
1168 stack. This facilitates making use of more clever algorithms (not
1169 implemented) for selecting relevant frames and gives a cleaner
1170 design since selection of frames can be done independently of
1171 extraction of frames from the real stack.
1172 (scm_stack_id): Also take #t as argument which means look at
1175 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1176 Turn n_tail into an integer directly representing current number
1177 of frames in stack. Add field tail.
1179 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1181 * debug.c (scm_make_memoized): Made it available at scheme level.
1182 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1183 SCM_NIMP before applying heavier predicates in argument checking.
1184 (scm_local_eval): Also take memoized object as argument.
1186 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1187 aren't created with zero length, but should such a strange
1188 creature suddenly turn up...
1190 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1192 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1193 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1195 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1197 * variable.c (scm_make_variable): Make the name hint optional, as
1199 (anonymous_variable_sym): Renamed from variable_sym. All uses
1202 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1203 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1204 of scm_primitive_load_path was also changed to
1205 "primitive-load-path", from "%try-load-path". Callers changed.
1206 We'd like to respect the convention that a function named
1207 "try-mumble" should behave just like the function called "mumble",
1208 but return #f instead of signalling some error.
1209 * load.h: Rename prototypes.
1211 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1213 * print.c (make_print_state, grow_print_state), print.h: Modified
1214 the print state representation: Don't use a tail array for
1215 recording of circular references. Resizing of the print state
1216 structure invalidates the print state pointer. To avoid passing
1217 around an indirect print state reference to all printing
1218 functions, we instead let the print state reference a resizable
1221 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1223 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1224 Don't crash when passed an improper list terminated by a
1225 non-immediate value.
1227 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1229 Allocate data for structures on an eight-byte boundary, as
1230 required by the tagging system.
1231 * struct.c (alloc_struct): New function.
1232 (scm_make_struct, scm_make_vtable_vtable): Call it.
1233 * struct.h (scm_struct_n_extra_words): Bump to 3.
1234 (scm_struct_i_ptr): New "field".
1235 * gc.c (scm_gc_sweep): When we need to free the data, use the
1236 information stored by alloc_struct to find the beginning of the
1237 block allocated to the structure, so we can free it.
1239 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1241 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1244 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1245 (scm_debug_info): New member: id.
1247 * stacks.c: Stacks are now represented as structs; Stacks have an
1248 id given to them by `start-stack'.
1249 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1251 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1252 Changed stack representation.
1254 * debug.c (scm_procedure_name): Try procedure property `name' for
1255 compiled closures aswell.
1257 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
1259 * eval.c: scm_i_name moved to gsubr.c
1260 (scm_m_define): Record names of all kinds of procedure
1261 objects. (Earlier, only closures were recorded.)
1263 * procprop.h: Added declaration of scm_i_name.
1265 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1266 (scm_make_gsubr): Record names of compiled closures.
1268 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1270 * debug.c, debug.h: Removed obsolete code.
1272 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1273 stacks.c: Renamed regs --> scm_contregs.
1275 * print.c (scm_free_print_state): Cleanup print state before
1276 returning it to pool. It is better to do it here than in
1277 scm_prin1 since scm_prin1 is called often.
1279 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1280 s_set_source_property_x): Check that first argument is a pair or a
1283 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1284 scm_i_line, scm_i_column and scm_i_breakpoint global.
1286 * init.c: Added #include "backtrace.h" and #include "stacks.h".
1287 (scm_boot_guile_1): Added calls to scm_init_backtrace and
1290 * debug.h: Added debug object smob declaration and macro
1293 * configure.in: Build with backtrace.o and stacks.o if debug
1296 * Makefile.in: Added entries for new files: backtrace.c,
1297 backtrace.h, stacks.c and stacks.h.
1299 * symbols.c (scm_sym2ovcell): Fixed documentation.
1301 * _scm.h (min, max): Added.
1303 * async.c: Moved `min' macro to _scm.h.
1305 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1306 SCM_BACKTRACE_INDENT.
1308 * eval.c: Added new debug options `maxdepth' and `indent'.
1310 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
1312 * print.h: Added selector SCM_PRINT_STATE.
1314 * print.c: New functions: scm_make_print_state,
1315 scm_free_print_state.
1317 * print.h: Added declarations for scm_make_print_state,
1318 scm_free_print_state.
1320 * debug.c (scm_m_start_stack): New acro.
1322 * debug.h: Small cleanup.
1324 * init.c (scm_boot_guile_1): Moved scm_init_debug below
1327 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

1347 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,

1349 declare functions with prototypes. (Patch thanks to Marius
1352 More prototype-related changes from Marius Vollmer:
1353 * gdb_interface.h: Wrapped header file in #ifdef/#endif
1354 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
1355 * ports.h (ptobfuns): Added prototypes. This means some casting in
1357 * fports.c: Added casts for initializations, since the functions
1358 are defined to take FILE * as their stream argument, not SCM.
1359 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
1360 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
1361 to `char *str_data' to conform to prototype.
1363 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1365 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
1367 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
1369 * stime.c, stime.h: use SCM_P method.
1371 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1373 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
1374 be given at least two arguments. Insist that lst's last element
1375 be a list, but don't make any requirements of its predecessors.
1377 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1379 * eval.c (scm_nconc2last): Revert last change; there seems to be
1380 other stuff going on here.
1382 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1384 * eval.c (scm_nconc2last): Make sure that each element of lst
1385 (which is a list of argument lists, except for the tail) is a
1386 proper list, i.e., finite and terminated by '().
1388 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1390 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
1393 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
1394 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
1397 * vectors.c (scm_make_vector): Fill vectors with the undefined
1398 value, to help make Guile Scheme code more portable to other
1401 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
1402 * symbols.h, tags.h: Doc fixes.
1404 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
1406 * async.c (scm_take_signal): Doc fixes.
1408 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
1410 * numbers.c (scm_divbigint): When the remainder is zero, we don't
1411 want to subtract it from the modulus; we just want to leave it
1414 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
1416 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
1419 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
1421 * throw.c (scm_catch_apply): Finished implementation of
1424 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
1426 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
1428 (scm_init_filesys): set "i/o-extensions" feature.
1431 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
1433 * Makefile.in (root.o): Correct dependencies.
1435 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
1437 * Makefile.in: Added dependency entry for root.o.
1439 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
1440 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
1442 * init.c (scm_start_stack): Set initial root continuation number
1445 * procs.c: New function: scm_thunk_p.
1447 * procs.h: Added declarations of scm_thunk_p.
1449 * root.c: Renamed `call-with-new-root' -->
1450 `call-with-dynamic-root'.
1451 (cwdr): Removed allocation of new root state. This should be done
1452 separately by use of scm_make_root.
1453 (scm_apply_with_dynamic_root): New function: Does what it
1454 sounds like. Needed when spawning threads.
1456 * root.h: Added member last_debug_frame to root state.
1457 Added #include "libguile/debug.h"
1459 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
1460 arguments. The motivation is that code in root.c needs catch
1461 functionality, and we want to avoid code duplication.
1462 New functions: scm_catch, scm_lazy_catch. These are wrappers for
1463 scm_catch_apply. scm_lazy_catch is intended to introduce catch
1464 handlers that run without popping the stack into the dynwind
1467 * throw.h: Added prototypes for scm_catch_apply and
1470 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1472 * root.h (scm_root, scm_set_root): Decouple thread support details
1473 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
1474 SCM_SET_THREAD_LOCAL_DATA.
1476 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
1477 and tortoise scanning loop.
1479 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
1481 * Makefile.in: Rebuild dependencies.
1483 * libguile.h: #include "libguile/print.h" before "smob.h", since
1484 the latter uses the print_state structure.
1486 * throw.c (scm_ithrow): Use the correct variable when checking to
1487 see if a given element of scm_dynwinds is a valid catch.
1489 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
1490 structure, abort; don't just silently ignore the garbage.
1492 * _scm.h: #include "print.h" here, since it seems to be used just
1494 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
1495 strports.c, unif.h: Don't #include "print.h".
1497 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1499 * feature.h (scm_loc_features): Removed external declaration.
1500 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
1502 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1504 * feature.c (scm_init_feature): Added threads feature (needs to be
1505 initialized here, since features doesn't exist when
1506 scm_init_threads is called).
1508 * libguile.h: Added #include "libguile/../threads/threads.h".
1509 (This is a kludge to get thread support working. This should be
1512 * configure.in, acconfig.h: Added flags for thread support.
1514 * scmsigs.c: Define `signal' to be `pthread_signal' if using
1517 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
1518 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
1521 * _scm.h: Added conditional #include "threads.h"
1523 * __scm.h (SCM_ASYNC_TICK): Added call to macro
1524 SCM_THREADS_SWITCHING_CODE.
1526 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
1527 allocate the basic dynamic root object.
1528 (scm_boot_guile): Added call to scm_init_root.
1530 * root.c, root.h: Added root smob.
1531 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
1532 functions: Implements dynamic roots mostly according to spec in
1533 SCM manual. Main difference is that the second argument is a
1534 throw handler rather than an error "thunk".
1536 * root.h: Added declaration of scm_init_root.
1538 * root.c: Added #include "genio.h", #include "smob.h", #include
1539 "pairs.h", #include "throw.h", #include "dynwind.h", #include
1541 (scm_init_root): Added #include "root.x".
1543 * throw.c: Added #include "stackchk.h"
1544 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
1545 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
1546 can be used in scm_call_with_new_root; Added reenabling of stack
1547 checking when catching a throw.
1549 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
1551 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
1553 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
1554 element is not found, as per R4RS.
1556 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1558 * list.c: Doc fixes throughout.
1560 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1562 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
1563 declare the char * to be const. Avoids a warning in rgx.c.
1565 * ports.h: spelling fix.
1567 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
1570 * load.c (scm_sys_try_load_path): throw an error if file not found
1571 (like it says it in NEWS).
1573 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1575 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
1576 PROPS slot to '(), not #f; it's an empty alist.
1578 * throw.h, throw.c: Use SCM_P instead of #if hair.
1580 Remove special support for uncaught throws; see throw.c for
1582 * throw.c (uncaught_throw): New function.
1583 (scm_ithrow): Call uncaught_throw if we don't find a throw
1584 target; don't mess with scm_bad_throw_vcell.
1585 (scm_bad_throw_vcell): Variable deleted.
1586 (scm_init_throw): Don't initialize it.
1588 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
1591 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1593 * numbers.c (scm_istr2int): If the number is short (as most
1594 numbers are), just call scm_small_istr2int to deal with it.
1595 (scm_small_istr2int): New function, created by un-#ifdefing the
1596 non-bignum version of scm_istr2int and renaming it.
1598 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
1600 * load.c (scm_sys_try_load): don't check whether value returned
1601 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
1602 Change the Scheme name from %try-load to primitive-load.
1604 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
1605 Can avoid passing a message, allowing it to be derived in the
1606 error handler (e.g., if we want to throw to the key both from
1609 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
1611 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
1612 references now have a new appearance which is more compact and
1613 also gives a clue about what the target of the reference is.
1614 By setting parameters in the print state, more fancy printing can
1615 be achieved. This is used by the (not yet commited) backtrace
1618 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
1620 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
1623 * print.c: Added #include "struct.h". Removed function
1626 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
1627 scm_iprin1. Removed prototype for scm_prlist.
1629 * arbiters.c (prinarb),
1630 async.c (print_async),
1631 debug.c (prindebugobj, prinmemoized),
1632 eval.c (prinprom, prinmacro),
1633 filesys.c (scm_fd_print, scm_dir_print),
1635 mallocs.c (prinmalloc),
1636 numbers.c, numbers.h (scm_floprint, scm_bigprint),
1637 smob.h (scm_smobfuns),
1638 srcprop.c (prinsrcprops),
1640 unif.c, unif.h (scm_raprin1, rapr1),
1641 variable.c (prin_var): Changed argument `int writing' to
1642 `scm_print_state *pstate'.
1644 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
1645 that it will be called before scm_init_print.
1647 * print.c (scm_prin1): Print states are now allocated when calling
1648 scm_prin1 and then passed around to all printing functions as an
1649 argument. A cache `print_state_pool' enables reuse of print
1651 (scm_make_print_state): New function.
1652 (scm_iprin1): Adaption to print states.
1653 (scm_iprlist): An initial "hare and tortoise" scan brings down
1654 time complexity to O (depth * N). (Better time complexity will be
1655 achieved when the printing code is completely rewritten.)
1657 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1659 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
1660 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
1661 it gets done whether or not the cache variable has a value.
1663 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
1665 Distinguish #f and ().
1666 * __scm.h: #undef SICP.
1667 * pairs.h (SCM_EOL): Delete this definition, equating it with
1669 * tags.h (SCM_EOL): Give it a new definition here; I think I found
1670 the value it used to have. Doc fixes, too.
1672 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
1674 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
1675 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
1676 Lord's implementation of structs, allowing for tail arrays as
1677 described in the manual. Also fixed some bugs. (Both the interface
1678 and the implementation should be improved.)
1680 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
1682 * print.c, print.h: Closures now print like #<procedure foo (x)>.
1683 People who whish to see the source can do `(print-enable 'source)'.
1684 Removed #ifdef DEBUG_EXTENSIONS.
1686 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1688 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
1689 integer (assuming for now accepting an integer is a good thing).
1691 * error.c, fports.c: replace use of %S in lgh_error args with %s.
1692 %S will be used instead for write'ing arguments.
1694 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
1695 asserts. fix a few other asserts.
1696 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
1697 scm_uniform_vector_ref, scm_array_set_x,
1698 scm_dimensions_to_unform_array): change args in
1699 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
1700 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
1701 scm_substring_fill_x): likewise.
1702 gsubr.c (scm_gsubr_apply): likewise.
1703 eval.c (SCM_APPLY): likewise.
1705 * eval.c (4 places): replace scm_everr with lgh_error or
1708 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
1709 scm_memory_error): new procedures.
1710 scm_everr: deleted. can use scm_wta, dropping first two args.
1711 scm_error: convert NULL subr to SCM_BOOL_F.
1713 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
1716 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
1719 * error.c, error.h: new error keys: scm_arg_type_key,
1720 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
1722 scm_wta: reimplement using lgh_error instead of scm_everr.
1724 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
1726 * gdbint.c: scm_lread now has one more argument.
1728 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
1729 scm_port_\1; Added mutator scm_set_port_filename_x (used when
1730 loading source from non-file ports, which, e. g., happens when
1731 using the Emacs interface).
1733 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
1736 * read.c: Added code for recording of positions of source code
1737 expressions; New functions: recsexpr, scm_lreadrecparen;
1738 _scm_make_srcprops --> scm_make_srcprops
1739 (scm_flush_ws): Removed updating of positions counters. This work
1740 is already done by scm_gen_getc
1742 * read.h: Added prototype for scm_lreadrecparen
1744 * print.c: Added #include "alist.h"
1746 * eval.c: Added #include "hash.h"
1748 * eq.c: Added #include "ramap.h"
1750 * options.c: Documentation fixes.
1752 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
1753 (scm_init_srcprop): Adjusted size of initial source-whash. Name
1754 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
1755 --> scm_make_srcprops
1757 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
1758 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
1759 function calls in the definition of the whash access macros.
1761 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
1763 * init.c (scm_boot_guile): Add level of indirection to
1764 scm_boot_guile_1() to ensure that stack base pointer is properly
1765 initialized. There was no guarantee that variable i was the
1766 highest/lowest variable on stack (i.e. the call frame of
1767 scm_boot_guile was not completely protected from gc).
1769 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
1771 * ports.h (scm_port_table): put back file_name, it will be used to
1772 support debugging. Undo related changes in fports.c, ioext.c,
1775 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1777 * ports.h (scm_port_table): remove file_name member for now, it seems
1779 * fports.c (scm_open_file): don't set file_name in PTAB.
1780 (prinfport): don't use file_name in PTAB.
1781 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
1782 * ports.c (scm_add_to_port_table): don't intialize file_name.
1783 (scm_port_file_name): remove for now.
1784 * gc.c (scm_gc_mark): don't mark PTAB file_name.
1786 * fports.h (scm_mkfile): prototype deleted.
1787 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
1789 * debug.c, unif.c: use scm_out_of_range instead of
1790 wta for range errors (ASSERT still needs work).
1792 * error.c, error.h (scm_out_of_range): new procedure.
1794 * error.c, error.h (scm_out_of_range_key): new key.
1796 * posix.c (scm_sync): #else was missing.
1798 * error.c, error.h: append _key to names scm_num_overflow and
1801 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
1802 of consing an empty list.
1803 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
1804 of macros, saves code and string space.
1805 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
1806 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
1807 lower case. Rename scm_syserror_m to scm_syserror_msg.
1808 error.h: prototypes for new procedures.
1810 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
1812 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
1814 * error.c, error.h: setup scm_num_overflow key.
1816 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
1817 Remove definition of SCM_OVSCM_FLOW.
1819 * fports.c (scm_open_file): use SCM_SYSERROR_M.
1821 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
1822 explicit message and args.
1824 * error.c, error.h, __scm.h: change system_error_sym to
1827 * error.c (system_error_sym): remove leading %% from the Scheme name
1830 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
1832 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1834 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
1835 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
1836 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
1837 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
1838 renamed. (These were introduced by unsupervised name
1841 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1843 * print.c: Added code for detection of circular references during
1844 printing. (init_ref_stack, grow_ref_stack): New functions. Added
1845 a hook for printing of closures (accessible via print options).
1846 This leads to a split of calls to scm_iprin1 into two classes:
1847 elementary print operations (e. g. the code which prints a smob)
1848 still use scm_iprin1 while top level calls (like scm_display) use
1849 scm_prin1. scm_prin1 begins by clearing the data structure used
1850 to record reference information.
1852 * print.h: Added declarations of scm_prin1 and scm_prlist.
1854 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
1856 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
1858 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
1860 * error.c (err_head): scm_iprin1 --> scm_prin1
1862 * debug.c: Adjusted header comment.
1866 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>

1870 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1872 * gdbint.c (gdb_read): Now possible to run during GC.
1873 (unmark_port, remark_port): New functions.
1875 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
1877 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
1878 of allocating a new string object. Also, increase size by
1879 the factor 2 instead of 1.5.
1881 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
1883 * __scm.h (SCM_P): Corrected to run under traditional C.
1885 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
1888 * async.c: Calls to scm_sysintern corrected.
1890 * async.h (scm_async_clock): Redundant declaration removed.
1892 * continuations.c (scm_dynthrow): Redundant declaration removed.
1894 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
1895 Definition typos corrected.
1897 * debug.h: Missing declarations of functions in debug.c added
1900 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
1901 Missing declarations to functions in eval.c added.
1903 * filesys.c: Possibly uninitialized variable rv.
1905 * gc.h (scm_object_addr, scm_unhash_name): Missing
1906 declarations of functions defined in gc.c added.
1908 * genio.c: Possible typos str_data -> wstr_data. ???
1910 * genio.c: Possibly unintended shadowing of local variable
1911 `int c' (gotos out of scope of inner `c'). ???
1913 * init.c: Uninitialized `SCM last' may be used.
1915 * ioext.h: (scm_sys_isatty_p): Typo.
1917 * list.h (scm_list_head): Missing prototype for function in
1920 * numbers.c (scm_two_doubles): Changed from extern to static
1921 (is used only within numbers.c).
1923 * numbers.h: Repeated declarations removed.
1925 * ports.h (scm_close_all_ports_except): Declaration for the
1926 function defined in ports.c added.
1928 * posix.h: Missing declarations added.
1930 * procs.h (scm_make_subr_opt): Missing declaration added.
1932 * socket.h (scm_sys_gethost): Missing declaration added.
1934 * socket.h: Redundant declarations removed (they are in fdsocket.h).
1936 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
1937 Missing declarations added.
1939 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
1941 * struct.c: Uninitialized variable `SCM answer' may be used.
1943 * unif.c (l2ra): Declaration prototype.
1945 * unif.c (scm_array_equal_p): Dummy definition removed (it is
1946 defined in ramap.c).
1948 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
1949 Redundant declarations removed (they are in ramap.h).
1951 * variable.h (scm_make_udvariable,
1952 scm_make_undefined_variable): Declaration corrected to
1953 correspond variable.c.
1955 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
1956 Missing declarations added.
1958 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
1960 * Makefile.in (distclean): Don't forget to delete fd.h.
1962 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1964 * fd.h.in, tags.h: Trivial cleanups.
1966 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
1967 marksweep.h just declared functions from gc.c.
1968 * gc.h, libguile.h: Don't #include "marksweep.h".
1969 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
1970 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
1971 dependencies updated.
1973 * libguile.h: Don't #include "files.h"; it's been deleted.
1975 * files.c (scm_sys_delete_file): Moved to filesys.c.
1976 File is now empty; deleted.
1978 * filesys.c: scm_sys_delete_file is now here. Remove
1979 #if's; they seem to rely on remnants of an old portability
1980 regimen. If the problems come up again, solve them properly,
1981 using autoconf. Specifically: Don't test M_SYSV, and #define
1982 remove to be unlink if it's #defined; don't use remove just
1983 because HAVE_STDC_HEADERS is #defined.
1984 * filesys.h: Add declarations for scm_sys_delete_file.
1985 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
1986 files.o, files.h, files.c, and files.x.
1987 * init.c: Don't #include "files.h", and don't call scm_init_files.
1989 Use SCM_P instead of PROTO; the latter intrudes on the user's
1991 * params.h: Deleted; definition of SCM_P moved to...
1992 * __scm.h: ... here, where it replaces PROTO macro.
1993 * libguile.h, smob.h: Don't #include "params.h".
1994 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
1995 smob.h: Fix prototypes accordingly.
1996 * Makefile.in: Update dependencies.
1997 (inner_h_files): Remove params.h.
1999 * gc.c: #include "gc.h"; every module should include its header,
2000 to let the compiler cross-check the declarations against the
2003 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2004 simpos.h: #include "libguile/__scm.h".
2006 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2008 * init.c: Don't forget to #include smob.h and init.h.
2009 * Makefile.in: Dependencies updated.
2011 * smob.h: Use PROTO instead of #if __STDC__.
2013 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2015 * __scm.h: Doc fixes.
2017 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2018 <angles>; this allows `make depends' to work properly.
2020 * libguile.h: #include smob.h and pairs.h before the others; they
2021 define typedefs used by other headers.
2023 C files should #include only the header files they need, not
2024 libguile.h (which #includes all the header files); the pointless
2025 recompilation was wasting my time.
2026 * Makefile.in (all .o dependency lists): Regenerated.
2027 * libguile.h: Don't try to get a definition for size_t here...
2028 * __scm.h: Do it here.
2029 * _scm.h: Since this is the internal libguile header, put things
2030 here that all (or a majority) of the libguile files will want.
2031 Don't #include <libguile.h> here; that generates dependencies on
2032 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2033 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2034 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

2131 * weaks.c: Get "weaks.h".
2133 * stackchk.h: #include "libguile/debug.h",
2135 * print.h, read.h: #include "options.h", since everyone who uses
2136 either of these files will need that.
2138 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2139 anyone who uses this file will need them to define the smob
2140 printing functions. Also, get markers.h, since people will need
2141 to #define the mark functions.
2143 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2144 * ports.h: ... to here.
2146 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2147 don't rely on archaic C default type rules.
2149 * fports.h: #include "libguile/ports.h", since you need that in
2150 order to parse this.
2152 * genio.h: #include "libguile/print.h", because you need that to
2153 parse this; don't bother #including "ports.h", since print.h gets
2156 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2158 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2159 this; it's now a reference to an element of *scm_root.
2161 * debug.h: Don't #include "options.h"; the compiler won't be able
2162 to find that once the headers are installed; instead, #include
2163 "libguile/options.h".
2164 * gc.h: Same, with marksweep.h.
2165 * mbstrings.h: Same, with symbols.h.
2166 * scmhob.h: Same, with _scm.h.
2167 * smob.h: Same, with params.h.
2169 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2170 C files; there's no need for this, and it forces recompilations
2173 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2175 * error.c (scm_error): declare scm_error_callback.
2177 * error.h: prototype for scm_error_callback.
2179 * __scm.h: define lgh_error.
2180 (SCM_SYSERROR): redefine using lgh_error.
2182 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2184 * error.c (scm_error): new procedure.
2186 * error.h: prototype for scm_error.
2188 * Makefile.in (install): install scmconfig.h from the current
2189 directory, not $(srcdir).
2191 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2193 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2194 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2195 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
2196 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
2197 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
2198 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2199 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2200 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2201 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2202 vports.h, weaks.h: #include "libguile/__scm.h", not
2203 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2204 dependencies are within libguile properly.
2206 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2208 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2209 when scmconfig.h doesn't exist.
2211 * load.c (scm_sys_try_load): Correct spelling.
2213 * feature.c (scm_loc_features): Make this static.
2215 * Makefile.in (libpath.h): Omit trailing slash from path. We
2216 shouldn't require it of users, so why put it here?
2218 Move code to initialize and search %load-path from ice-9 to C
2219 code, so we can use the load-path to find the ice-9 boot code;
2220 this makes it easier to run Guile without installing it. See
2221 corresponding changes in guile/Makefile.in.
2222 * feature.c: Move stuff concerned with the load path to load.c.
2223 (scm_compiled_library_path): Deleted.
2224 Don't #include libpath.h here.
2225 * feature.h: Don't mention scm_compiled_library_path.
2226 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2227 <sys/stat.h>, and <unistd.h> (if present).
2228 (R_OK): #define if the system hasn't deigned to.
2229 (scm_loc_load_path): New variable.
2230 (scm_init_load_path, scm_sys_search_load_path,
2231 scm_sys_try_load_path): New functions.
2232 (scm_init_load): Initialize scm_loc_load_path to point to the
2233 value cell of the Scheme %load-path variable.
2234 * load.h: Add declarations for scm_sys_search_load_path,
2235 scm_sys_try_load_path.
2236 * init.c: Call scm_init_load_path.
2237 * Makefile.in (feature.o, load.o): Dependencies updated.
2239 * load.c, load.h: Rewrite using PROTO macro.
2241 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2243 * gc.c (scm_cellp): New function: C predicate to determine if an
2244 SCM value can be regarded as a pointer to a cell on the heap.
2246 * gc.h: Added declaration of scm_cellp.
2248 * gdb_interface.h: New file: The GDB interface header from the GDB
2251 * gdbint.c: New file: GDB interface.
2253 * gdbint.h: New file: GDB interface.
2255 * libguile.h: Added #include <libguile/gdbint.h>.
2257 * init.c (scm_boot_guile): Added scm_init_gdbint.
2259 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2260 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2261 found if object files and source are kept separate).
2263 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2265 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2267 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2269 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2270 TK_SRC_DIR; they're not relevant any more.
2272 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2273 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2275 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2277 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2278 search path, so we can find the <libguile/MUMBLE.h> headers.
2280 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2282 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2283 implicit in the .c.o rule.
2284 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2287 Put the library path in a header file, instead of passing it on
2288 the command line in every compilation.
2289 * Makefile.in (libpath.h): New target.
2290 (feature.o): Depend on libpath.h.
2291 (clean): Delete libpath.h.
2292 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2293 * feature.c: ... #include "libpath.h" here.
2294 * .cvsignore: Ignore libpath.h.
2296 Don't install the unwashed masses of Guile header files in the
2297 main #include path; put most of them in a subdirectory called
2298 'libguile'. This avoids naming conflicts between Guile header
2299 files and system header files (of which there were a few).
2300 * Makefile.in (pkgincludedir): Deleted.
2301 (innerincludedir): New variable; this and $(includedir) are enough.
2302 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
2303 (installed_h_files): Divide this up. Now this variable lists
2304 those header files which should go into $(includedir) (i.e. appear
2305 directly in the #include path), and ...
2306 (inner_h_files): ... this new variable says which files appear in
2307 a subdirectory, and are referred to as <libguile/mumble.h>.
2308 (h_files): List them both.
2309 (install): Create innerincludedir, not pkgincludedir. Put
2310 the installed_h_files and inner_h_files in their proper places.
2311 (uninstall): Corresponding changes.
2312 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2313 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2314 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
2315 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
2316 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
2317 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2318 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2319 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2320 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2321 vports.h, weaks.h: Find __scm.h in its new location.
2322 * __scm.h: Find scmconfig.h and tags.h in their new locations
2323 (they're both "inner" files).
2325 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
2327 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
2329 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2331 * posix.c: Doc fixes.
2333 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
2335 * socket.c: Don't include a prototype for inet_aton; just use a
2336 K&R style declaration, to avoid warnings but minimize the chance
2337 of conflicts with the system.
2339 On NextStep, <utime.h> doesn't define struct utime, unless we
2340 #define _POSIX_SOURCE before #including it.
2341 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
2342 * acconfig.h: New comment text for above CPP symbol.
2343 * configure.in: Call it.
2344 * posix.c: #define _POSIX_SOURCE if it seems necessary.
2346 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
2348 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
2349 testing for __EMX__.
2351 * posix.c: #include <libc.h>, if it exists.
2353 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
2354 don't even know if the latter exists.
2356 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
2357 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
2358 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
2360 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
2362 (scm_init_posix): Use them when initializing the Scheme constants
2365 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2367 * Makefile.in (libdir, includedir, bindir): Use the
2368 autoconf-supplied values, instead of deriving them ourselves.
2369 (pkgincludedir, datadir, pkgdatadir): New variables.
2370 (install, uninstall): Put the header files in a special
2371 subdirectory, not in the main search path.
2373 * Makefile.in (ALL_CFLAGS): Provide the proper value for
2374 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
2376 * Makefile.in (IMPLPATH): Deleted; never used.
2378 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
2379 on the Tcl/Tk source any more.
2380 (INCLUDE_CFLAGS): Remove references to the above.
2382 * Makefile.in (version.o): Corrected dependencies.
2384 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
2386 * libguile.h: #include "version.h"
2388 * init.c (scm_boot_guile): Call scm_init_version.
2389 * gscm.c (gscm_run_scm): Call scm_init_version.
2391 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
2392 GUILE_VERSION): AC_DEFINE these.
2393 (acconfig.h): #undef the above symbols.
2395 * Makefile.in (libobjs): Add version.o.
2396 (installed_h_files): Add version.h.
2397 (c_files): Add version.c.
2398 (gen_c_files): Add version.x.
2399 (version.o): New rule.
2400 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
2401 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
2402 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
2403 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,

2409 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
2410 weaks.o): Add version.h to dependency lists.
2411 (markers.o): Remove duplicate rule.
2413 * version.h: New file.
2415 * version.c: New file.
2417 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2419 * symbols.c (scm_strhash): scm_downcase is now a function, not an
2420 array; use it appropriately. Since GCC is quite happy to
2421 subscript functions, it never warned us about this; we should use
2422 -Wpointer-arith in the future. I guess we never tested
2425 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2427 * socket.c: Doc and copyright fixes.
2429 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2431 * debug.c: Fixed and improved gdb support.
2433 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2435 * socket.c: Added declaration of inet_aton to avoid compiler
2436 warning. (Hope this solution is correct.)
2438 * stime.c: Added declaration of ftime. (This is missing in
2441 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
2443 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2445 * Makefile.in (c_files): add strerror.c.
2447 * strerror.c: new file from Emacs' sysdep.c.
2448 maybe configure should also check for sys_errlist.
2450 * configure.in (AC_REPLACE_FUNCS): add strerror.
2452 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2454 * debug.c (scm_init_debug): Added initialization for
2455 scm_evaluator_traps.
2457 * debug.h, debug.c: Various name changes.
2458 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
2459 "debug-options-interface". See commentary in options.c.
2461 * options.h, options.c: Options now have documentation strings.
2462 Also added a long explanatory commentary.
2464 * eval.c, print.h, print.c, read.h, read.c: Modifications to
2467 * gscm.c, init.c, root.c, throw.c: Bug fixes:
2468 last_debug_info_frame is now updated in all cases.
2470 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
2473 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2475 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
2476 Added option STACK_CHECKING.
2478 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
2480 * Makefile.in: Added {debug,options,srcprop}.{h,c}
2482 * __scm.h: Removed symbols for debugging support.
2484 * acconfig.h: Added symbols for debugging support.
2486 * configure.in: Added user option for debugging support.
2487 --enable-debug will include the debugging code into libguile.a.
2489 * continuations.c (scm_make_cont): Enlarged the #if 0 around
2490 scm_relocate_chunk_to_heap.
2492 * debug.c: New file: low-level debugging support. It also
2493 includes support for debugging with gdb. (The extensions to gdb
2494 are written by Per Bothner at Cygnus.)
2496 * debug.h: New file: low-level debugging support.
2498 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
2499 argument pairs. Extensive modifications to the debugging
2500 evaluator. Added "SECTION:" commentaries to clarify what happens
2501 when, during double compilation. Renamed EVALIMP --> EVALIM.
2502 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
2503 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
2504 the beginning of the file. New procedure: scm_unmemocopy.
2505 Added some global state variables needed by the debugging
2506 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
2507 check_entry, check_apply, check_exit, debug_options and
2508 evaluator_traps. New acro: undefine.
2510 * eval.h: Renamed EVAL --> XEVAL.
2512 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
2513 --> scm_make_weak_key_hash_table.
2515 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
2516 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
2518 * libguile.h: Conditionally include debug.h
2520 * objprop.c (scm_object_properties, scm_set_object_properties_x):
2521 scm_object_properties shouldn't return handle. `handle' now gets
2522 initialized in scm_set_object_properties_x. scm_object_properties
2523 doesn't any longer create an entry in scm_object_whash.
2525 * options.c: New file: handling of run time options.
2527 * options.h: New file: handling of run time options.
2529 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
2531 * print.c: New procedure: scm_print_options
2533 * print.h: Defines for print options.
2535 * read.c: New procedure: scm_read_options
2537 * read.h: Defines for reader options.
2539 * root.h: Added scm_source_whash among scm_sys_protects.
2541 * srcprop.c: New file: source properties.
2543 * srcprop.h: New file: source properties.
2545 * throw.c (jbsmob): Jump buffers are now correctly allocated.
2546 (Bug found by A. Green.)
2548 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2550 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2552 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
2554 * libguile.h: #include "objprop.h"; I guess this was forgotten.
2556 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
2557 and should be called by the final client.
2559 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
2561 * gc.h: Use the PROTO macro when declaring functions.
2562 * gc.c: Use the PROTO macro when declaring static functions.
2563 Remove the CPP hair around function definitions.
2565 * gc.c (scm_init_storage): Initialize scm_asyncs.
2567 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
2568 preprocessor symbol; "__scm.h" is where it might get #defined.
2569 * __scm.h: Similar: #include <scmconfig.h> before testing
2572 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
2574 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
2576 * init.c (scm_boot_guile): Add init_func argument; call
2577 (*init_func) instead of calling scm_appinit; it's ucky to
2578 hard-code names for the user's procedures.
2579 * init.h (scm_boot_guile): Adjust declaration.
2581 * __scm.h (PROTO): New macro, for declaring functions with
2584 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
2585 eliminate all the __STDC__ conditionals.
2586 (scm_boot_guile): Add declaration.
2587 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
2588 Remove __STDC__ conditionals around function definitions; the
2589 declarations in init.h will provide the same information, more
2592 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
2593 complain about it in the error message; the error message is
2594 adequate without that note, and there's nothing the user can do
2597 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
2599 * Makefile.in (ancillary): Drop def.sed.
2601 * posix.c (scm_init_posix): Use numeric values, rather than
2602 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
2603 F_OK. The symbols aren't available on some systems, and I'm
2604 pretty sure their values are fixed by common widespread practice.
2605 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
2607 More functions unavailable on some systems.
2608 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
2609 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
2611 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2612 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
2613 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
2614 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
2615 stub that signals an error as the #else.
2617 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
2619 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
2621 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
2623 * unif.c: include ramap.h.
2625 * read.c (endif): case_insensative_p renamed case_insensitive_p.
2627 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
2629 * ports.c: include sys/ioctl.h.
2631 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
2633 * configure.in: check for sys/ioctl.h.
2635 * ports.c: include <malloc.h> not "malloc.h".
2637 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2639 * fports.c: remove ttyname and tmpnam declarations.
2641 * posix.c: fewer ttyname declarations.
2643 * fports.c: include <string.h> not "string.h".
2645 * init.c, ioext.c: include string.h and unistd.h.
2647 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2649 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
2650 genio.c, simpos.c, vports.c: include string.h.
2652 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
2654 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
2656 (scm_addr_buffer_size): change type from scm_sizet to int.
2657 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
2658 from scm_sizet to int.
2660 * error.c: include unistd.h.
2662 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
2665 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
2667 * __scm.hd, def.sed: deleted.
2669 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
2671 Changes for NeXT, suggested by Robert Brown.
2672 * configure.in: Call AC_TYPE_MODE_T.
2673 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
2674 NeXT. Put header file list in alphabetical order.
2675 * configure, scmconfig.h.in: Regenerated.
2676 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
2678 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
2681 * acconfig.h: New file, providing documentation for the CPP
2682 symbols defined in configure.in
2683 * acconfig-1.5.h: Removed; superceded by the above.
2685 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
2687 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
2689 * fports.c (scm_open_file): don't return #f, throw error.
2691 * ioext.c (fileno): renamed from %fileno.
2692 (soft-fileno): deleted.
2694 * ports.c (scm_port_revealed): don't need to check for -1 from
2696 (scm_set_port_revealed_x): return unspecified, not #f.
2698 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
2700 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
2702 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
2704 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
2706 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2708 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
2709 This is necessary on Ultrix, and doesn't hurt portability.
2711 * Makefile.in (dist-dir): New target, implementing a new dist system.
2712 (installed_h_files): Put in alphabetical order.
2713 Remove duplicate entries for markers.h and unif.h.
2714 (c_files): Remove duplicate entries for markers.c.
2715 (ancillary): Renamed from anillery; all uses changed. Remove
2716 PLUGIN; it's a directory, and needs special treatment in dist-dir.
2717 Remove all the ../doc/* files; doc/Makefile.in handles that.
2719 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
2721 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
2722 every if must have an else, or else the whole command has a
2723 non-zero exit code whenever the if's condition is false.
2725 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
2727 * posix.c: include string.h.
2729 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2731 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
2734 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
2735 Remove leading % from scheme names.
2736 Do not return error values, call SCM_SYSERROR or similar.
2738 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
2740 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
2742 * struct.c (scm_init_struct): new file.
2744 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
2746 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
2747 (scm_list_head): added list-head for rapidly chopping argument
2748 lists off of longer lists (and similar).
2750 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
2752 * objprop.c (scm_object_property): assq the cdr of the whash
2753 handle for obj, not the handle itself.
2755 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
2757 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
2758 weak hash tables last of all marking to avoid an obscure gc bug.
2759 WARNING: circular lists stored in a weak hash table will hose us.
2761 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
2763 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
2764 new functions similar to scm_substring_move_left_x and
2765 scm_substring_move_right_x.
2767 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
2769 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
2772 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
2774 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
2776 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
2778 * strports.c (scm_strprint_obj): convenience function. C for
2779 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
2781 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
2782 removed to a separate library
2784 * init.c (scm_boot_guile): copied from guile-tcl.c.
2785 Initialization specific to tcl interpreters removed.
2787 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
2789 * ports.c (scm_ports_prehistory): size malloced here doesn't
2790 matter so long as it is non-0 (got rid of "* 4").
2792 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
2794 * gscm.h: gscm_mkarray eliminated (presumably was not being used
2795 since its definition was bogus).
2797 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
2799 * mallocs.[ch]: back again (for rx at least).
2801 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
2803 * ports.c: removed functions relating to the mapping between ports
2804 and descriptors. (That stuff is unix-specific and should be collected
2805 in a separate library).
2807 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
2808 (Tom Mckay@avanticorp.com)
2810 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
2812 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
2813 handled correctly (SCM_FREEP was applied to them) -- test for
2814 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
2815 being overwritten with #f. (brown@grettir.bibliotech.com)
2817 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
2819 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
2820 for a specific symbol or for all symbols.
2822 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
2824 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
2825 keys and weak values confused).
2827 Thu Mar 14 22:20:20 1996 Tom Lord <lord@beehive>
2829 * list.c (scm_last_pair): map '()=>'()
2831 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>
2833 * pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:
2834 Generalized assoc and hash-table functions.
2835 Factored pairs.c into multiple files.
2837 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
2839 * gscm.c (gscm_run_scm): got rid of objprop.
2841 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
2843 * genio.c (scm_getc):
2844 NOTE: fgetc may not be interruptable.
2846 * procprop.c (scm_stand_in_scm_proc):
2847 NOTE: don't use a alist here.
2848 (scm_set_procedure_properties_x): fix type checking throughout this file.
2850 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
2852 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
2853 after freeing part of the port table.
2855 Thu Feb 29 16:21:17 1996 Tom Lord <lord@beehive>
2857 * strports.c (scm_mkstrport):
2858 * vports.c (scm_make_soft_port): allocate a port table entry
2859 (possibly triggering gc) before setting the tag of the corresponding
2862 * pairs.c (scm_delq_x): never throw an error.
2864 * vectors.c (scm_make_vector): made the default vector fill argument
2865 into '() (much more useful than the previous value, "#unspecified")
2867 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
2869 * ports.c (scm_add_to_port_table): Added fields
2870 to port table entries: file_name, line_num, col.
2871 Update these in open_file, gen_getc and gen_ungetc.
2872 Added procedures to access those fields.
2874 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
2876 * procs.c (scm_make_subr_opt): new entry point for making
2879 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
2881 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
2883 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
2885 * numbers.c (scm_exact_p): This function no longer
2886 implements "integer?".
2888 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
2890 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
2891 (scm_gc_stats): return an assoc of useful data. Replaces "room"
2892 and the stats reporting formerlly built into repl.
2894 * repl.[ch]: removed.
2895 GC statistics keeping moved to gc.c.
2896 Other statistics keeping can be done from Scheme.
2897 REPLS are now written in Scheme.
2899 Wed Feb 21 10:28:53 1996 Tom Lord <lord@beehive>
2901 * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky
2902 conservatively marked objects).
2904 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
2906 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
2908 * feature.c (scm_compiled_library_path): moved here from repl.c.
2909 This file is for stuff relating specifically to Scheme libraries
2912 * eval.c (scm_m_define): don't give warning about redefinition, don't
2915 NOTE: this should throw a resumable exception with parameters --

2982 initialization to fix a race condition.
2984 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

3008 set the multi_byte flag correctly in symbols. This is wrong.
3009 intern_obbary_soft and msymbolize should take an extra parameter.
3010 Also, weird multibyte symbols don't print correctly.
3011 The weird symbol syntax is also a bit bogus (emacs doesn't quite
