1 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
4 used from C to easily lookup the value of a symbol in the current
7 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
9 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
10 scm_init_unif in this file. This will also fix a previous problem
13 * configure.in: Added AM_MAINTAINER_MODE
15 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
17 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
20 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
22 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
23 source files that are not always included in libguile but should
24 have their dependencies calculated by automake. This variable is
25 recognized by automake, no further magic is needed.
26 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
27 to deal exclusively with *.lo files, as it seems. The *.o files
28 are built automatically when the corresponding *.lo file gets
31 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
33 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
36 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
38 * unif.c (scm_array_set_x): minor change to argument error checking.
40 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
42 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
43 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
44 They should only be included in the library at configure.in's
46 (libguile_la_LDADD): Include the appropriate .lo files here.
47 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
48 so we know when to build them (and their .lo bretheren).
49 * configure.in (LIBLOBJS): New substituted variable. We let
50 configure decide which .o files to include in LIBOBJS, and then
51 put the corresponding list of .lo files in LIBLOBJS. The latter
52 is what we pass to libtool.
53 * Makefile.in, configure: regenerated.
55 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
57 * symbols.c (scm_sysintern0): New function. Contains the core of
58 old scm_sysintern but doesn't take a second value argument.
59 (scm_sysintern): Now uses scm_sysintern0.
60 (scm_sysintern_no_module_lookup): Renamed to
61 scm_sysintern0_no_module_lookup and doesn't take a second value
64 * symbols.h (scm_sysintern0: Added declaration.
66 * options.c (scm_init_opts): Use scm_sysintern0 instead of
67 scm_sysintern when interning option keys. Otherwise we risk
68 destroying the values of already interned variables.
70 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
71 scheme-level boolean (use SCM_NFALSEP).
73 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
75 (scm_backtrace): New function. (C version of old function from
76 boot-9.scm) Motivation: Make it possible to display backtraces
77 without depending on boot-9.scm. (I'm uncertain if this
78 motivation is good enough...)
80 * root.h (scm_root_state): Add member the_last_stack_var.
81 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
83 * root.c (mark_root): Mark scm_the_last_stack_var.
85 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
88 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
90 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
91 1. mark_lazy_catch didn't mark the smob.
92 2. Both functions above have standard variants:
93 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
94 free_lazy_catch --> scm_free0.
96 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
98 * throw.c (scm_internal_lazy_catch): New function.
99 (scm_lazy_catch): Rewritten to use it.
100 (scm_ithrow): Handle the new lazy catch representation.
101 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
102 that doesn't have a jmpbuf is a lazy catch clause.
103 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
104 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
105 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
107 (scm_init_throw): Register the new lazy-catch smob type.
108 * throw.h (scm_internal_lazy_catch): decl for new function.
110 * throw.c (scm_internal_catch): Doc fixes.
112 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
113 configure.in. Including this might cause problems if applications
114 that link against libguile include their own copies of alloca, but
115 if they're using autoconf, they should be adding libguile to LIBS
116 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
117 the copy in libguile, and things will be okay. (I think.)
119 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
121 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
123 strop.h: move prototypes too.
125 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
127 * posix.c (scm_init_posix): don't intern EINTR since it's now done
130 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
131 etc. I deleted them from filesys.c long ago, but didn't
132 notice they were here too (although ineffective since
133 sys/stat.h wasn't included).
135 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
137 * eval.c: Don't define alloca in GCC case. gcc will automatically
138 use __builtin_alloca if appropriate.
140 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
142 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
143 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
144 that values of automatic variables are preserved. See comments
145 for safe_setjmp for details.
147 Change from Thomas Morgan:
148 * variable.c: Include eq.h.
149 (var_equal): New function.
150 (variable_smob): Use var_equal as the discriminator for variables.
152 * throw.c (s_throw): Remove extraneous declaration.
154 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
155 * eval.c: Add necessary CPP cruft to support that.
156 * configure, Makefile.in, scmconfig.h.in: regenerated.
158 Change from Thomas Morgan:
159 * procprop.c (scm_procedure_properties): Convert the Scheme
160 boolean returned by scm_procedure_p into a C boolean before using
161 it as a condition for SCM_ASSERT.
162 (scm_procedure_property): Likewise.
164 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
165 indications of Unixness.
168 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
170 * * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
172 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
174 * read.c (scm_lreadr): use scm_misc_error to improve one of the
175 "unknown # object" error messages.
177 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
178 (scm_i_index) and declare it static. Add a 'direction' argument
179 to indicate what way the search should go.
180 (scm_i_index): throw out-of-range error instead of wrong-type-arg
182 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
183 strop.h: remove scm_i_index, scm_i_rindex prototypes.
185 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
187 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
189 * * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
190 to avoid clash with various scsh forks.
192 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
194 The following two changes (ramap.c, throw.c) are motivated by the
195 apparent unportability of forward declarations of static arrays of
196 the form `static foo bar[];'.
198 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
199 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
201 * throw.c (scm_throw): Moved above scm_ithrow.
203 * options.h: Removed the extern declarations of scm_yes_sym and
204 scm_no_sym since these are static.
206 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
208 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
210 * Makefile.am: remove AWK=@AWK@.
211 Add a rule for generating errnos.list.
212 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
214 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
215 don't extract errnos, just set a variable (avoids the
216 need to recompile error.c just because configure is run.)
218 * unif.h: update prototypes.
219 * unif.c (scm_uniform_array_read,write): change the offset and
220 length arguments to start and end, for consistency.
222 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
224 * ioext.h: update prototypes.
225 * * ioext.c (scm_read_delimited_x): replaces scm_read_line and
226 scm_read_line_x, it's a more general procedure using an
227 interface from scsh. read-line and read-line! are now defined
229 * Note that the new read-line trims the terminator
230 by default, previously it was appended to the returned string. An
231 optional argument specifies how to process the terminator (scsh
232 compatible). For the old behaviour: (read-line port 'concat).
233 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
234 returns a pair, but is converted to multiple values if the scsh
237 socket.h: update prototypes.
238 * socket.c (scm_recvfrom): for consistency with other procedures,
239 take start and end as separate optional arguments.
240 * (scm_recv, scm_recvfrom): don't allow the second argument
241 to be a size, only a buffer. Change the scheme names to
242 recv! and recvfrom!. Don't return the buffer.
244 * ioext.h, posix.h: move prototypes too.
245 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
246 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
247 "read.h" and "unif.h".
248 * ioext.c: include "chars.h"
250 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
252 * dynl.c: The dynamic linking and module registration functions
253 are now defined even when dynamic linking is not available for the
254 host system. Some of their functionality can be done without
255 dynamic linking; when it's really needed, they throw errors.
257 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
259 * configure.in: Only define DYNAMIC_LINKING when one of the system
260 dependent functions is detected.
261 * dynl.c (scm_dynamic_func): New function to get the address of a
262 function in a dynamic object.
263 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
264 produced by scm_dynamic_func as the thing to call.
266 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
268 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
269 (scm_register_module_xxx, scm_registered_modules,
270 scm_clear_registered_modules): New functions.
272 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
274 * symbols.c (scm_sysintern): Renamed to
275 scm_sysintern_no_module_lookup.
276 (scm_sysintern): New function to take the place of the old
277 scm_sysintern. It uses the current toplevel lookup closure to give
278 the symbol its value. This is a temporary hack to put packages
279 like gtcltk into their own module.
280 (scm_can_use_top_level_lookup_closure_var): New variable to tell
281 us whether `scm_top_level_lookup_closure_var' has been initialized
283 * eval.c (scm_init_eval): Set it.
285 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
287 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
288 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
290 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
292 * (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
293 scm_sys_dup): deleted: FD capability will be added to other
295 * Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
296 scm_fd_free, fd_smob, scm_intern_fd.
297 * (scm_open): renamed from scm_sys_open. Return a port instead of
298 an FD object. Make the mode argument optional.
299 * (scm_sys_create): deleted, it's just a special case of open.
300 (scm_init_filesys): move interning of constants O_CREAT etc.,
301 here (were previously using SCM_CONST_LONG macro).
302 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
304 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
305 include "fports.h" and <stdio.h>
306 (scm_stat, scm_select): don't support FD objects.
308 * error.h: adjust scm_syserror_msg prototype.
309 * error.c (scm_syserror_msg): take an extra argument for errno.
310 Using the global value didn't always work, since it could be
311 reset by procedure calls in the message or args arguments.
313 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
314 I don't understand why the check was there (and what about the
317 * strop.c (scm_string_copy): allow shared substrings to be copied.
319 * unif.h: corresponding change to prototypes.
320 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
321 recognize two new optional arguments: offset and length. Allow
322 the port argument to be an integer (file descriptor, for scsh).
323 Include <unistd.h> for "read" prototype.
325 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
327 * socket.c: don't include filesys.h.
329 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
331 * Makefile.am: add AWK=@AWK@ (?)
333 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
335 Add a rule to generate errnos.c from errnos.
336 * error.c (scm_init_error): include errnos.c.
337 * errnos_cnvt.awk: new file, converts the list of errno codes to
339 * errnos_get.c: new file.
340 * errnos.default: new file, contains errnos to try if they can't
341 be extracted from errno.h.
342 * configure.in: if using GCC, try and extract errno codes from
346 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
348 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
349 * Makefile.am: Made libguile into a libtool library.
350 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
351 Set libtool_libs to indicate that libguile is a libtool library.
352 See guile/ChangeLog for details.
353 * .cvsignore: ignore "*.lo", the libtool library objects.
355 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
357 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
358 use htons in getservbyport argument.
360 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
362 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
363 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
366 * objprop.c (scm_object_property): No need to take the CDR of the
367 value returned by scm_object_properties, since Aug 20 change.
369 * configure.in: When checking for struct linger, #include
370 <sys/types.h> as well as <sys/socket.h>. I've never known
371 <sys/types.h> to cause any portability problems, and Solaris's
372 <sys/socket.h> needs it.
373 * configure: Rebuilt.
375 I think the Sun compiler has chosen a perverse way to interpret
376 ANSI declarations combined with K&R definitions. We'll
377 appease it a little bit. But when it invades France, we fight.
378 * print.c (scm_iprlist): Change 'tlr' argument to an int.
379 * print.h (scm_iprlist): Here too.
380 * numbers.c (scm_divbigdig): Change definition to match
381 declaration in numbers.h.
382 * unif.c (scm_makflo): Change definition to match declaration in
385 * init.c (scm_boot_guile): Don't return the value of
386 scm_boot_guile_1. This function doesn't return a value;
387 scm_boot_guile_1 doesn't return a value (or return at all).
389 * eval.c (unmemocopy): Add a semicolon to appease the Sun
392 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
393 compile. I have a feeling this function is a bad idea anyway ---
394 one should always test for features, not systems.
396 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
397 semicolons. Only pure luck kept this from being noticed earlier.
399 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
401 * socket.c (scm_recvfrom): Added missing semicolon.
403 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
405 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
406 the buffer and start and end positions for scsh networking
409 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
411 * configure.in: Revert previous change to this file; the problem
412 is due to transient automake weirdness.
413 * configure: Rebuilt.
415 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
416 PLUGIN/guile.libs. configure generates the latter from the former.
417 * Makefile.in: Rebuilt.
419 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
420 need this if we install scripts, like guile-snarf.
421 * configure: Rebuilt.
423 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
425 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
427 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
429 * socket.c (scm_addr_vector): fix faulty scm_listify.
431 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
433 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
434 style block comment is no longer considered an error.
436 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
438 * PLUGIN/guile.libs.in: New file.
439 * PLUGIN/guile.libs: Removed from repository.
440 * configure.in: Create PLUGIN/guile.libs from
441 PLUGIN/guile.libs.in. This is for including additonal libraries
442 needed for dynamic linking.
443 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
444 instead of PLUGIN/guile.libs.
446 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
448 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
450 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
451 occurrences of the given element from the list, not just the
452 first. This is how the Emacs Lisp functions behave, how the
453 analogous Common Lisp functions behave, and (I believe) how the
454 older Maclisp functions worked. I realize that this change may
455 break code, but it seemed better to break it before the Guile
458 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
459 Their prototypes were already present in gc.h, but they weren't
461 (scm_init_storage): Initialize scm_protects.
462 * root.c (scm_protects): New element of scm_sys_protects.
464 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
466 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
468 * libguile.h: Added #include "libguile/net_db.h".
470 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
471 30 change. That file is only meant for communication between the
472 configuration process and load.c. If code linked against libguile
473 wants to get at the paths mentioned in libpath.h, it can call
474 functions declared in load.h.
476 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
478 * libguile.h: Removed #include "libguile/fdsocket.h"
480 * net_db.c: Added #include <sys/socket.h>.
482 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
484 * filesys.c (scm_input_waiting_p): use select in preference to
485 FIONREAD, since the latter doesn't detect EOF.
486 Throw error if neither select nor FIONREAD available.
488 * socket.c (scm_connect): take a port, not a fd object.
489 (scm_fill_sockaddr): throw an error if fam is not recognised.
490 (scm_bind): use scm_fill_sockaddr.
491 (scm_listen): take a port, not a fd object.
492 (scm_accept): take and return a port. return #f in the car if
494 (scm_sock_fd_to_port): new procedure.
495 (scm_socket): use scm_sock_fd_to_port.
496 (scm_addr_vector): throw error if unrecognised address type.
497 take an extra argument with the calling procedure name.
498 (scm_getsockname): take a port. return #f if address can't be got.
499 (scm_getpeername): take a port. return #f if address can't be got.
500 (scm_recvfrom): take a port. return #f for address component if can't
502 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
503 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
505 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
507 * throw.c (scm_internal_catch): Make body funcs and handler funcs
508 use separate data pointers, to allow them to be designed
509 independently and reused.
510 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
511 Renamed from catch_body, catch_handler, and uncaught_throw; made
513 (struct scm_catch_body_data): Renamed from catch_body_data; moved
515 (scm_catch): Use the above.
516 (scm_throw): Don't bother printing a message for an uncaught
517 throw; we establish a default handler in init.
518 * throw.h (scm_internal_catch): Prototype updated.
519 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
521 (struct scm_body_thunk_data): New structure, used as data
522 argument to scm_body_thunk.
523 * init.c (struct main_func_closure): New structure, packaging up
524 the data to pass to the user's main function.
525 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
526 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
527 scm_internal_catch to establish a catch-all handler, using
528 scm_handle_by_message. This replaces the special-case code in
530 (invoke_main_func): Body function for scm_internal_catch; invoke
531 the user's main function, using the main_func_closure pointer to
532 decide what to pass it.
533 * root.c (struct cwdr_body_data): Remove handler_proc member.
534 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
535 (cwdr_handler): Removed.
537 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
539 * socket.h (SCM_P): update bind prototype.
540 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
542 (scm_socket): return a port, not a file descriptor object.
543 include "fports.h" and <unistd.h>
544 (scm_bind): take a port, not a file descriptor object.
545 take an extra argument for address args.
547 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
548 INADDR_NONE, INADDR_LOOPBACK.
550 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
552 * init.c: include net_db.h and not fdsocket.h.
553 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
555 * Makefile.am: corresponding changes.
556 * socket.h: renamed from fdsocket.h, fix names.
557 * net_db.h: renamed from socket.h, fix names.
558 * socket.c: renamed from fdsocket.c.
559 remove _sys from procedure names.
560 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
561 add "socket" to features list.
562 * net_db.c: renamed from socket.c.
563 remove _sys from procedure names.
564 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
565 add "net-db" to features list.
566 include "net_db.h". don't include <sys/socket.h> or
569 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
571 * tags.h (scm_tags): Removed comma at end of last enumerator.
573 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
575 Don't use GCC extensions to allocate space for debugging frames.
576 (Here he goes again! Why do we put up with this?!)
577 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
578 an scm_debug_info structure, not an in-line array of them. Add
579 'info' member, to say how many vect elements we've used, for eval
581 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
582 a new variable debug_info_end to mark the end of vect, instead of
583 the address of the 'info' pointer itself.
584 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
585 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
586 (SCM_APPLY): Explicitly allocate space for debug.vect.
587 * debug.c (scm_m_start_stack): Same, for vframe.vect.
588 * stacks.c: Adjusted for new debug frame structure.
589 (RELOC_INFO, RELOC_FRAME): New macros.
590 (stack_depth, read_frames): Use them, and new scm_debug_frame
591 element 'info', instead of magically knowing that eval frames have
592 an info pointer sitting after vect.
593 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
595 (scm_init_stacks): Formatting tweaks.
597 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
599 Give GCC more control flow information, so it can be sure that
600 variables aren't used uninitialized.
601 * error.h (scm_error, scm_syserror, scm_syserror_msg,
602 scm_sysmissing, scm_num_overflow, scm_out_of_range,
603 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
604 scm_misc_error): Tell GCC that these functions never return.
605 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
606 out the field type, call abort if SCM_ASSERT returns, to placate
608 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
609 scm_wta ever returns. We can't handle this case anyway, and this
610 gives the optimizer more information.
611 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
612 scm_wta ever returns.
614 In some cases, the code is fine, but GCC isn't smart enough to
615 figure that out; this usually happens when one variable is only
616 initialized and used when a particular condition holds true, and
617 we know that condition will never change within a given invocation
618 of the function. In this case, we simply initialize the variables
619 to placate the compiler, hopefully to a value which will cause a
620 crash if it is ever actually used.
621 * print.c (scm_iprin1): Initialize mw_pos.
622 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
623 * throw.c (scm_ithrow): Initialize dynpair.
624 * unif.c (scm_uniform_vector_ref): Initialize cra.
625 * struct.c (init_struct): Initialize prot.
626 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
628 * strports.c (scm_eval_0str): Don't return uninitialized garbage
629 if EXPR contains no expressions.
631 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
633 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
634 cause an infinite loop (???). So much for the algebraic
635 equivalency of variable-sized arrays and alloca...
637 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
639 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
640 a SCM boolean, not a C boolean.
642 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
644 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
645 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
646 rules for raising scm_mtrigger. Previously, unfortunate but not
647 unlikely circumstances could result in almost constant invokation
648 of the gc. Now, this situations should be less likely, but they
649 are not prevented completely.
651 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
653 * numbers.c (scm_fuck): Procedure removed; looks like old test
655 * numbers.h: Prototype removed.
657 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
659 * debug.h (scm_debug_frame): Change `vect' member from an in-line
660 array to a pointer, to match my Nov 21 change in eval.c.
662 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
664 * libguile.h: Added #include "libguile/backtrace.h", #include
667 * strings.c (scm_string scm_make_string scm_string_ref
668 scm_string_set_x scm_string_equal_p scm_string_append):
669 Bugfix according to scm patch from Aubrey Jaffer:
670 Corrected long-standing
671 (not (eqv? (integer->char 128)
672 (string-ref (make-string 1 (integer->char 128)) 0)))
673 bug found by John Kozak <jk@noontide.demon.co.uk>.
675 * strports.c, strports.h: Make scm_eval_0str return the value of
676 the last expression evaluated (previously, it returned void).
678 * strports.c, strports.h: New function: scm_read_0str. Does what
681 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
683 * simpos.c (scm_getenv): return #f if string can't be found in the
684 environment instead of throwing an exception, for compatibility
685 with numerous other systems.
687 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
689 * Makefile.am (.c.x): Use guile-snarf.
690 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
692 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
694 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
696 * backtrace.c (scm_display_error_message): Made non-static, and
697 renamed from display_error_message.
698 * backtrace.h (scm_display_error_message): Added extern decl.
699 * throw.c (uncaught_throw): Use it to display the error message.
701 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
703 * inet_aton.c: Use #if 0, not #ifdef 0.
705 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
707 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
708 to convert the returned value.
709 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
712 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
714 Add new interface to catch/throw, usable from C as well as
716 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
717 (scm_internal_catch): New function, replaces...
718 (scm_catch_apply): Deleted.
719 * throw.c (scm_catch_apply): Deleted; replaced with a more general
720 mechanism which is a bit more code, but can be used nicely from C
721 and implement the Scheme semantics as well.
722 (scm_internal_catch): This is the replacement; it's named after
723 the analogous function in Emacs.
724 (scm_catch): Reimplemented in terms of the above.
725 (struct catch_body_data, catch_body, catch_handler): New
726 functions, used by scm_catch.
727 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
728 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
729 support for new cwdr.
731 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
734 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
736 * acconfig.h: Added DYNAMIC_LINKING symbol.
737 * configure.in: Add option and checks for dynamic linking.
738 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
739 dynl.h: New files for dynamic linking support.
740 * Makefile.am (libguile_a_SOURCES):
742 (modinclude_HEADERS): Added "dynl.h".
743 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
745 * init.c (scm_boot_guile_1): Call
746 scm_init_dynamic_linking to initialize dynamic linking support.
748 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
750 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
751 (as we Schemers say). It needs to be global, so that I can tweak
752 it for the proper operation of unexec.
753 (scm_boot_guile_1_live): New variable, see above.
755 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
757 * guile-snarf.sh: Removed.
758 * PLUGIN/guile.libs: Added dependency for -lm.
759 * acinclude.m4: Renamed from aclocal.m4.
760 * PLUGIN/greet: Removed.
761 * Makefile.am, aclocal.m4: New files.
762 * configure.in: Updated for Automake.
764 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
766 * eval.c (scm_definedp): Use top_level_lookup_closure_var
767 and not top_level_lookup_thunk_var.
769 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
771 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
773 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
775 * eval.c (scm_definedp): Incompatibly changed to be a builtin
776 Scheme function, instead of syntax. Single argument is now a
779 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
781 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
782 scm_ra_divide): Properly terminate statements passed as arguments
783 to IVDEP macros. (Thanks to Bernard Urban.)
785 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
786 with non-constant sizes. (Thanks to Bernard Urban.)
788 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
790 It's an "eval closure", not an "eval thunk." A thunk is a
791 function of no arguments.
792 * root.h (struct scm_root_state): Renamed
793 top_level_lookup_closure_var from top_level_lookup_thunk_var.
794 (scm_top_level_lookup_closure_var): Renamed from
795 scm_top_level_lookup_thunk_var.
796 * root.c (mark_root): Uses changed.
797 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
798 * init.c (scm_start_stack): Uses changed.
799 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
800 Change scheme-visible name to *top-level-lookup-closure* from
801 *top-level-lookup-thunk*.
803 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
805 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
806 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
808 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
810 * gc.c (struct scm_heap_seg_data): Doc fixes.
812 * gc.c (scm_gc_sweep): Empty all segments' freelists before
813 sweeping. Then, prepend each segment's free cells to its
814 freelist, rather than wiping out the old value. (Thanks to Marius
817 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
818 scm_check_freelist, scm_debug_newcell): New functions and
819 variables, for debugging freelist problems.
820 * pairs.h (SCM_NEWCELL): New debugging version added.
821 * gc.h (scm_debug_newcell): Added extern declaration, used by
822 debugging version of SCM_NEWCELL.
824 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
826 On some systems <libc.h> conflicts with <unistd.h>, and should not
828 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
829 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
830 * configure.in: Call it.
831 * posix.c, filesys.c: Use its results to decide whether or not to
833 * configure, scmconfig.h.in: Rebuilt with autoconf and
836 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
838 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
839 pointer to the stdio stream before calling scm_setbuf0, so the
840 latter will be able to retrieve it. I'm surprised this didn't
841 segfault earlier. (Thanks to Christopher Lee.)
843 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
845 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
848 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
850 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
851 number of stack narrowing specifier pairs. The first specifier in
852 a pair controls inner border, the second the outer border. A
853 number means cut that number of frames, a procedure object means
854 cut until that object is found in operator position in a frame.
856 * root.c (cwdr): Bugfix.
858 * read.c: Recording of positions disabled by default.
860 * procs.c (scm_closure_p): New function.
862 * posix.c (scm_tmpnam): New function.
864 * load.c: Added #include "throw.h".
865 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
868 * load.c, load.h (scm_read_and_eval_x): New function.
870 * eval.c: Renamed debug option "deval" to "debug".
872 (scm_eval_x): `eval!' is no longer accessible from the scheme
873 level. Motivation: We can't allow operations which introduce
874 glocs into the scheme level. Guile's type system can't handle
875 these as data. Use `eval' or `read-and-eval!' as replacement.
877 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
878 SCM_CONSP since this is a macro!; Set vframe.prev to
879 scm_last_debug_frame instead of 0. In this way we can look
880 "above" the virtual start stack frame if we wish.
881 (scm_debug_hang): New function: Useful for debugging Guile in
882 certain tricky situations. Will probably be removed later...
884 * debug.h: Changed semantics of debug option "backtrace". This
885 option now only indicates whether we want automatic backtrace at
888 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
890 * ports.c: #include "filesys.h"
891 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
893 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
894 Motivation: This is system specific code which is related to file
895 I/O. It also may use select. Added code by Gary Houston to
896 detect presence of character in stdio buffers.
898 * libguile.h: #include "libguile/libpath.h"
900 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
901 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
902 SCM_SITE_DIR; Install libpath.h among the other include files.
904 * load.c, load.h (scm_sys_package_data_dir): New function.
906 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
908 * stacks.h: Bugfix: Don't use tail-array length field as stack
909 length field! This screwed GC.
911 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
913 * _scm.h: Added #ifndef around definition of macros min and max.
915 * __scm.h: Added hooks for threads to plugin to in ints protection
916 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
917 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
918 the main code in these macros duplicated and spread over multiple
919 files. Renamed SCM_THREADS_SWITCHING_CODE ->
920 SCM_THREAD_SWITCHING_CODE.
922 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
925 * guile-snarf.sh: New file.
926 * Makefile.in (inner_h_files): Added snarf.h
927 (ancillary, install, uninstall, distclean): Added actions for
929 (.c.x): Use guile-snarf.
930 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
931 (gen_c_files): Note that these depend on guile-snarf.
932 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
933 now in "snarf.h". Added #include "snarf.h" to get them.
934 * libguile.h: Added #include "snarf.h".
935 (Patches applied and tweaked by Jim Blandy.)
937 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
939 * socket.c: Use K&R style declaration for 'close'; the GNU coding
940 standards suggest against providing prototypes for system
941 functions. Thanks to Greg Troxel.
943 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
945 * strports.c (scm_eval_0str): New function.
946 #include "read.h", to get prototype for scm_read.
947 * Makefile.in (strports.o): Update dependencies.
948 * strports.h: New prototype.
950 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
951 scheme name from "int?" to "integer?". It seems to do the job.
952 * numbers.h: Rename prototype too.
953 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
956 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
957 scm_num_eq_p): Rename these according to R4RS conventions: call
958 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
959 to making libguile R4RS compliant without ice-9...
961 * load.c (scm_sys_search_load_path): Search for files under all
962 extensions listed in the %load-extensions variable. If FILENAME
963 is absolute, return it unchanged, without searching the load path.
964 (scm_loc_load_extensions): New variable, pointing to
965 %load-extensions' value cell.
966 (scm_init_load): Initialize it, and the value it points to.
967 (scm_primitive_load_path): Improve error reporting.
969 * load.c (scm_loc_load_hook): New variable, pointing to value cell
970 of new Scheme variable %load-hook.
971 (scm_primitive_load): Apply %load-hook to filename.
973 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
975 * configure.in: add tests for figuring out whether buffered data
976 is available in a FILE structure, which is needed by char-ready.
978 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
981 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
982 exceptions using misc_error instead of syserror. It seems a bit
983 odd to throw an exception if a string can't be found in the
984 environment, but it's consistent with open-file, stat etc.
985 (simpos.h): remove sys_ from getenv.
987 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
988 occurs, throw an error instead of returning errno. Return value
990 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
992 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
994 * filesys.c (scm_stat2scm): derive file type and permissions from
995 the stat mode and append them to the returned vector.
996 There isn't much overhead in doing this and it avoids the need to
997 work with S_IRUSR et al. in Scheme.
998 Define symbols scm_sym_regular etc.
999 (scm_init_filesys): don't intern S_IRUSR etc.
1001 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1002 and s_primitive_load_path.
1004 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1006 * error.h: don't declare error symbols. prototype for scm_misc_error.
1008 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1011 * error.c: use SCM_SYMBOL to set up error keys.
1012 scm_misc_error: new procedure.
1014 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1016 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1017 between `#!' and `!#' is ignored.
1018 (skip_scsh_block_comment): New function.
1020 * feature.c (scm_set_program_arguments): New argument, FIRST.
1021 * feature.h: Update prototype.
1022 * init.c (scm_boot_guile_1): Pass new argument to
1023 scm_set_program_arguments.
1025 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1027 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1028 (scm_boot_guile): Call scm_set_program_arguments here, later than
1029 the old initialization.
1031 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1032 initialization procedure.
1033 - Delete in, out, err arguments; there are other perfectly good
1034 ways to override these when desired.
1035 - Delete result argument; this function shouldn't ever return.
1036 - Rename init_func argument to main_func, for less confusion.
1037 - Delete boot_cmd argument; main_func is more general.
1038 -Add 'closure' argument, to help people pass data to main_func
1039 without resorting to global variables.
1040 - Abort if reentered; don't bother returning an error code.
1041 - Call scm_init_standard_ports to set up the default/current
1042 standard ports; no need to pass them to scm_start_stack.
1043 - Remove code to evaluate the boot_cmd, and start the repl; let
1044 the user do something like that in main_func if they want.
1045 - Remove code to package up a return value; main_func can do any
1047 - Call exit (0), instead of returning.
1048 (scm_start_stack): Don't initialize the I/O ports here; that's
1049 weird. Delete in, out, err arguments. Move guts to
1050 scm_init_standard_ports, scm_stdio_to_port.
1051 (scm_init_standard_ports): New function, to set up current and
1052 default standard ports.
1053 (scm_start_stack, scm_restart_stack): Make these static.
1054 * init.h (scm_boot_guile): Adjust declaration.
1055 (scm_start_stack, scm_restart_stack): Remove externally
1056 visible declarations for these.
1057 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1059 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1060 written out several times in scm_start_stack.
1061 * fports.h: New declaration for the above.
1063 * feature.c (scm_set_program_arguments): New function.
1064 * feature.h: New declaration for the above.
1066 * ports.c: Formatting tweak.
1068 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1070 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1071 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1072 for obtaining the address of a car or cdr field. Motivation:
1073 &SCM_CXR make assumptions about the internal structure of the
1076 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1077 Motivation: see SCM_CXRLOC.
1079 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1080 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1081 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1082 Motivation: Safer use. Some other macros are defined in terms of
1083 these operations. If these are defined using the SCM_SETCXR
1084 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1085 to inefficiency and an <e1> with side-effects could potentially
1086 break. Also, these particular operations are heavily utilized in
1087 the garbage collector. In unoptimized code there will be a
1090 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1091 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
1092 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
1093 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
1094 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
1095 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1096 vports.c: Cleaned up use of pairs: Don't make any special
1097 assumptions about the internal structure of selectors and
1098 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1099 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1100 (Among other things, this change makes it easier to build Guile
1101 with certain compilers which have problems with casted lvalues.)
1103 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1105 * stacks.c: Improve selection of relevant stack frames when making
1106 a stack object. Introduce one level of indirection in the stack
1107 object to make it possible to "narrow" to a certain region of the
1108 stack. This facilitates making use of more clever algorithms (not
1109 implemented) for selecting relevant frames and gives a cleaner
1110 design since selection of frames can be done independently of
1111 extraction of frames from the real stack.
1112 (scm_stack_id): Also take #t as argument which means look at
1115 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1116 Turn n_tail into an integer directly representing current number
1117 of frames in stack. Add field tail.
1119 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1121 * debug.c (scm_make_memoized): Made it available at scheme level.
1122 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1123 SCM_NIMP before applying heavier predicates in argument checking.
1124 (scm_local_eval): Also take memoized object as argument.
1126 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1127 aren't created with zero length, but should such a strange
1128 creature suddenly turn up...
1130 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1132 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1133 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1135 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1137 * variable.c (scm_make_variable): Make the name hint optional, as
1139 (anonymous_variable_sym): Renamed from variable_sym. All uses
1142 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1143 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1144 of scm_primitive_load_path was also changed to
1145 "primitive-load-path", from "%try-load-path". Callers changed.
1146 We'd like to respect the convention that a function named
1147 "try-mumble" should behave just like the function called "mumble",
1148 but return #f instead of signalling some error.
1149 * load.h: Rename prototypes.
1151 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1153 * print.c (make_print_state, grow_print_state), print.h: Modified
1154 the print state representation: Don't use a tail array for
1155 recording of circular references. Resizing of the print state
1156 structure invalidates the print state pointer. To avoid passing
1157 around an indirect print state reference to all printing
1158 functions, we instead let the print state reference a resizable
1161 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1163 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1164 Don't crash when passed an improper list terminated by a
1165 non-immediate value.
1167 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1169 Allocate data for structures on an eight-byte boundary, as
1170 required by the tagging system.
1171 * struct.c (alloc_struct): New function.
1172 (scm_make_struct, scm_make_vtable_vtable): Call it.
1173 * struct.h (scm_struct_n_extra_words): Bump to 3.
1174 (scm_struct_i_ptr): New "field".
1175 * gc.c (scm_gc_sweep): When we need to free the data, use the
1176 information stored by alloc_struct to find the beginning of the
1177 block allocated to the structure, so we can free it.
1179 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1181 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1184 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1185 (scm_debug_info): New member: id.
1187 * stacks.c: Stacks are now represented as structs; Stacks have an
1188 id given to them by `start-stack'.
1189 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1191 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1192 Changed stack representation.
1194 * debug.c (scm_procedure_name): Try procedure property `name' for
1195 compiled closures aswell.
1197 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
1199 * eval.c: scm_i_name moved to gsubr.c
1200 (scm_m_define): Record names of all kinds of procedure
1201 objects. (Earlier, only closures were recorded.)
1203 * procprop.h: Added declaration of scm_i_name.
1205 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1206 (scm_make_gsubr): Record names of compiled closures.
1208 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1210 * debug.c, debug.h: Removed obsolete code.
1212 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1213 stacks.c: Renamed regs --> scm_contregs.
1215 * print.c (scm_free_print_state): Cleanup print state before
1216 returning it to pool. It is better to do it here than in
1217 scm_prin1 since scm_prin1 is called often.
1219 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1220 s_set_source_property_x): Check that first argument is a pair or a
1223 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1224 scm_i_line, scm_i_column and scm_i_breakpoint global.
1226 * init.c: Added #include "backtrace.h" and #include "stacks.h".
1227 (scm_boot_guile_1): Added calls to scm_init_backtrace and
1230 * debug.h: Added debug object smob declaration and macro
1233 * configure.in: Build with backtrace.o and stacks.o if debug
1236 * Makefile.in: Added entries for new files: backtrace.c,
1237 backtrace.h, stacks.c and stacks.h.
1239 * symbols.c (scm_sym2ovcell): Fixed documentation.
1241 * _scm.h (min, max): Added.
1243 * async.c: Moved `min' macro to _scm.h.
1245 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1246 SCM_BACKTRACE_INDENT.
1248 * eval.c: Added new debug options `maxdepth' and `indent'.
1250 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
1252 * print.h: Added selector SCM_PRINT_STATE.
1254 * print.c: New functions: scm_make_print_state,
1255 scm_free_print_state.
1257 * print.h: Added declarations for scm_make_print_state,
1258 scm_free_print_state.
1260 * debug.c (scm_m_start_stack): New acro.
1262 * debug.h: Small cleanup.
1264 * init.c (scm_boot_guile_1): Moved scm_init_debug below

1289 declare functions with prototypes. (Patch thanks to Marius
1292 More prototype-related changes from Marius Vollmer:
1293 * gdb_interface.h: Wrapped header file in #ifdef/#endif
1294 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
1295 * ports.h (ptobfuns): Added prototypes. This means some casting in
1297 * fports.c: Added casts for initializations, since the functions
1298 are defined to take FILE * as their stream argument, not SCM.
1299 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
1300 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
1301 to `char *str_data' to conform to prototype.
1303 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1305 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
1307 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
1309 * stime.c, stime.h: use SCM_P method.
1311 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1313 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
1314 be given at least two arguments. Insist that lst's last element
1315 be a list, but don't make any requirements of its predecessors.
1317 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1319 * eval.c (scm_nconc2last): Revert last change; there seems to be
1320 other stuff going on here.
1322 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1324 * eval.c (scm_nconc2last): Make sure that each element of lst
1325 (which is a list of argument lists, except for the tail) is a
1326 proper list, i.e., finite and terminated by '().
1328 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1330 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
1333 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
1334 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
1337 * vectors.c (scm_make_vector): Fill vectors with the undefined
1338 value, to help make Guile Scheme code more portable to other
1341 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
1342 * symbols.h, tags.h: Doc fixes.
1344 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
1346 * async.c (scm_take_signal): Doc fixes.
1348 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
1350 * numbers.c (scm_divbigint): When the remainder is zero, we don't
1351 want to subtract it from the modulus; we just want to leave it
1354 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
1356 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
1359 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
1361 * throw.c (scm_catch_apply): Finished implementation of
1364 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
1366 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
1368 (scm_init_filesys): set "i/o-extensions" feature.
1371 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
1373 * Makefile.in (root.o): Correct dependencies.
1375 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
1377 * Makefile.in: Added dependency entry for root.o.
1379 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
1380 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
1382 * init.c (scm_start_stack): Set initial root continuation number
1385 * procs.c: New function: scm_thunk_p.
1387 * procs.h: Added declarations of scm_thunk_p.
1389 * root.c: Renamed `call-with-new-root' -->
1390 `call-with-dynamic-root'.
1391 (cwdr): Removed allocation of new root state. This should be done
1392 separately by use of scm_make_root.
1393 (scm_apply_with_dynamic_root): New function: Does what it
1394 sounds like. Needed when spawning threads.
1396 * root.h: Added member last_debug_frame to root state.
1397 Added #include "libguile/debug.h"
1399 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
1400 arguments. The motivation is that code in root.c needs catch
1401 functionality, and we want to avoid code duplication.
1402 New functions: scm_catch, scm_lazy_catch. These are wrappers for
1403 scm_catch_apply. scm_lazy_catch is intended to introduce catch
1404 handlers that run without popping the stack into the dynwind
1407 * throw.h: Added prototypes for scm_catch_apply and
1410 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1412 * root.h (scm_root, scm_set_root): Decouple thread support details
1413 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
1414 SCM_SET_THREAD_LOCAL_DATA.
1416 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
1417 and tortoise scanning loop.
1419 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
1421 * Makefile.in: Rebuild dependencies.
1423 * libguile.h: #include "libguile/print.h" before "smob.h", since
1424 the latter uses the print_state structure.
1426 * throw.c (scm_ithrow): Use the correct variable when checking to
1427 see if a given element of scm_dynwinds is a valid catch.
1429 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
1430 structure, abort; don't just silently ignore the garbage.
1432 * _scm.h: #include "print.h" here, since it seems to be used just
1434 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
1435 strports.c, unif.h: Don't #include "print.h".
1437 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1439 * feature.h (scm_loc_features): Removed external declaration.
1440 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
1442 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1444 * feature.c (scm_init_feature): Added threads feature (needs to be
1445 initialized here, since features doesn't exist when
1446 scm_init_threads is called).
1448 * libguile.h: Added #include "libguile/../threads/threads.h".
1449 (This is a kludge to get thread support working. This should be
1452 * configure.in, acconfig.h: Added flags for thread support.
1454 * scmsigs.c: Define `signal' to be `pthread_signal' if using
1457 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
1458 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
1461 * _scm.h: Added conditional #include "threads.h"
1463 * __scm.h (SCM_ASYNC_TICK): Added call to macro
1464 SCM_THREADS_SWITCHING_CODE.
1466 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
1467 allocate the basic dynamic root object.
1468 (scm_boot_guile): Added call to scm_init_root.
1470 * root.c, root.h: Added root smob.
1471 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
1472 functions: Implements dynamic roots mostly according to spec in
1473 SCM manual. Main difference is that the second argument is a
1474 throw handler rather than an error "thunk".
1476 * root.h: Added declaration of scm_init_root.
1478 * root.c: Added #include "genio.h", #include "smob.h", #include
1479 "pairs.h", #include "throw.h", #include "dynwind.h", #include
1481 (scm_init_root): Added #include "root.x".
1483 * throw.c: Added #include "stackchk.h"
1484 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
1485 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
1486 can be used in scm_call_with_new_root; Added reenabling of stack
1487 checking when catching a throw.
1489 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
1491 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
1493 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
1494 element is not found, as per R4RS.
1496 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1498 * list.c: Doc fixes throughout.
1500 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1502 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
1503 declare the char * to be const. Avoids a warning in rgx.c.
1505 * ports.h: spelling fix.
1507 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
1510 * load.c (scm_sys_try_load_path): throw an error if file not found
1511 (like it says it in NEWS).
1513 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1515 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
1516 PROPS slot to '(), not #f; it's an empty alist.
1518 * throw.h, throw.c: Use SCM_P instead of #if hair.
1520 Remove special support for uncaught throws; see throw.c for
1522 * throw.c (uncaught_throw): New function.
1523 (scm_ithrow): Call uncaught_throw if we don't find a throw
1524 target; don't mess with scm_bad_throw_vcell.
1525 (scm_bad_throw_vcell): Variable deleted.
1526 (scm_init_throw): Don't initialize it.
1528 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
1531 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1533 * numbers.c (scm_istr2int): If the number is short (as most
1534 numbers are), just call scm_small_istr2int to deal with it.
1535 (scm_small_istr2int): New function, created by un-#ifdefing the
1536 non-bignum version of scm_istr2int and renaming it.
1538 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
1540 * load.c (scm_sys_try_load): don't check whether value returned
1541 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
1542 Change the Scheme name from %try-load to primitive-load.
1544 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
1545 Can avoid passing a message, allowing it to be derived in the
1546 error handler (e.g., if we want to throw to the key both from
1549 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
1551 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
1552 references now have a new appearance which is more compact and
1553 also gives a clue about what the target of the reference is.
1554 By setting parameters in the print state, more fancy printing can
1555 be achieved. This is used by the (not yet commited) backtrace
1558 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
1560 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
1563 * print.c: Added #include "struct.h". Removed function
1566 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
1567 scm_iprin1. Removed prototype for scm_prlist.
1569 * arbiters.c (prinarb),
1570 async.c (print_async),
1571 debug.c (prindebugobj, prinmemoized),
1572 eval.c (prinprom, prinmacro),
1573 filesys.c (scm_fd_print, scm_dir_print),
1575 mallocs.c (prinmalloc),
1576 numbers.c, numbers.h (scm_floprint, scm_bigprint),
1577 smob.h (scm_smobfuns),
1578 srcprop.c (prinsrcprops),
1580 unif.c, unif.h (scm_raprin1, rapr1),
1581 variable.c (prin_var): Changed argument `int writing' to
1582 `scm_print_state *pstate'.
1584 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
1585 that it will be called before scm_init_print.
1587 * print.c (scm_prin1): Print states are now allocated when calling
1588 scm_prin1 and then passed around to all printing functions as an
1589 argument. A cache `print_state_pool' enables reuse of print
1591 (scm_make_print_state): New function.
1592 (scm_iprin1): Adaption to print states.
1593 (scm_iprlist): An initial "hare and tortoise" scan brings down
1594 time complexity to O (depth * N). (Better time complexity will be
1595 achieved when the printing code is completely rewritten.)
1597 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1599 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
1600 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
1601 it gets done whether or not the cache variable has a value.
1603 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
1605 Distinguish #f and ().
1606 * __scm.h: #undef SICP.
1607 * pairs.h (SCM_EOL): Delete this definition, equating it with
1609 * tags.h (SCM_EOL): Give it a new definition here; I think I found
1610 the value it used to have. Doc fixes, too.
1612 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
1614 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
1615 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
1616 Lord's implementation of structs, allowing for tail arrays as
1617 described in the manual. Also fixed some bugs. (Both the interface
1618 and the implementation should be improved.)
1620 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
1622 * print.c, print.h: Closures now print like #<procedure foo (x)>.
1623 People who whish to see the source can do `(print-enable 'source)'.
1624 Removed #ifdef DEBUG_EXTENSIONS.
1626 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1628 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
1629 integer (assuming for now accepting an integer is a good thing).
1631 * error.c, fports.c: replace use of %S in lgh_error args with %s.
1632 %S will be used instead for write'ing arguments.
1634 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
1635 asserts. fix a few other asserts.
1636 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
1637 scm_uniform_vector_ref, scm_array_set_x,
1638 scm_dimensions_to_unform_array): change args in
1639 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
1640 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
1641 scm_substring_fill_x): likewise.
1642 gsubr.c (scm_gsubr_apply): likewise.
1643 eval.c (SCM_APPLY): likewise.
1645 * eval.c (4 places): replace scm_everr with lgh_error or
1648 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
1649 scm_memory_error): new procedures.
1650 scm_everr: deleted. can use scm_wta, dropping first two args.
1651 scm_error: convert NULL subr to SCM_BOOL_F.
1653 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
1656 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
1659 * error.c, error.h: new error keys: scm_arg_type_key,
1660 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
1662 scm_wta: reimplement using lgh_error instead of scm_everr.
1664 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
1666 * gdbint.c: scm_lread now has one more argument.
1668 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
1669 scm_port_\1; Added mutator scm_set_port_filename_x (used when
1670 loading source from non-file ports, which, e. g., happens when
1671 using the Emacs interface).
1673 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
1676 * read.c: Added code for recording of positions of source code
1677 expressions; New functions: recsexpr, scm_lreadrecparen;
1678 _scm_make_srcprops --> scm_make_srcprops
1679 (scm_flush_ws): Removed updating of positions counters. This work
1680 is already done by scm_gen_getc
1682 * read.h: Added prototype for scm_lreadrecparen
1684 * print.c: Added #include "alist.h"
1686 * eval.c: Added #include "hash.h"
1688 * eq.c: Added #include "ramap.h"
1690 * options.c: Documentation fixes.
1692 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
1693 (scm_init_srcprop): Adjusted size of initial source-whash. Name
1694 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
1695 --> scm_make_srcprops
1697 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
1698 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
1699 function calls in the definition of the whash access macros.
1701 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
1703 * init.c (scm_boot_guile): Add level of indirection to
1704 scm_boot_guile_1() to ensure that stack base pointer is properly
1705 initialized. There was no guarantee that variable i was the
1706 highest/lowest variable on stack (i.e. the call frame of
1707 scm_boot_guile was not completely protected from gc).
1709 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
1711 * ports.h (scm_port_table): put back file_name, it will be used to
1712 support debugging. Undo related changes in fports.c, ioext.c,
1715 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1717 * ports.h (scm_port_table): remove file_name member for now, it seems
1719 * fports.c (scm_open_file): don't set file_name in PTAB.
1720 (prinfport): don't use file_name in PTAB.
1721 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
1722 * ports.c (scm_add_to_port_table): don't intialize file_name.
1723 (scm_port_file_name): remove for now.
1724 * gc.c (scm_gc_mark): don't mark PTAB file_name.
1726 * fports.h (scm_mkfile): prototype deleted.
1727 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
1729 * debug.c, unif.c: use scm_out_of_range instead of
1730 wta for range errors (ASSERT still needs work).
1732 * error.c, error.h (scm_out_of_range): new procedure.
1734 * error.c, error.h (scm_out_of_range_key): new key.
1736 * posix.c (scm_sync): #else was missing.
1738 * error.c, error.h: append _key to names scm_num_overflow and
1741 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
1742 of consing an empty list.
1743 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
1744 of macros, saves code and string space.
1745 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
1746 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
1747 lower case. Rename scm_syserror_m to scm_syserror_msg.
1748 error.h: prototypes for new procedures.
1750 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
1752 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
1754 * error.c, error.h: setup scm_num_overflow key.
1756 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
1757 Remove definition of SCM_OVSCM_FLOW.
1759 * fports.c (scm_open_file): use SCM_SYSERROR_M.
1761 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
1762 explicit message and args.
1764 * error.c, error.h, __scm.h: change system_error_sym to
1767 * error.c (system_error_sym): remove leading %% from the Scheme name
1770 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
1772 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1774 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
1775 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
1776 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
1777 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
1778 renamed. (These were introduced by unsupervised name
1781 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1783 * print.c: Added code for detection of circular references during
1784 printing. (init_ref_stack, grow_ref_stack): New functions. Added
1785 a hook for printing of closures (accessible via print options).
1786 This leads to a split of calls to scm_iprin1 into two classes:
1787 elementary print operations (e. g. the code which prints a smob)
1788 still use scm_iprin1 while top level calls (like scm_display) use
1789 scm_prin1. scm_prin1 begins by clearing the data structure used
1790 to record reference information.
1792 * print.h: Added declarations of scm_prin1 and scm_prlist.
1794 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
1796 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
1798 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
1800 * error.c (err_head): scm_iprin1 --> scm_prin1
1802 * debug.c: Adjusted header comment.
1806 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1808 * strerror.c: Doc fix.
1810 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1812 * gdbint.c (gdb_read): Now possible to run during GC.
1813 (unmark_port, remark_port): New functions.
1815 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
1817 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
1818 of allocating a new string object. Also, increase size by
1819 the factor 2 instead of 1.5.
1821 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
1823 * __scm.h (SCM_P): Corrected to run under traditional C.
1825 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
1828 * async.c: Calls to scm_sysintern corrected.
1830 * async.h (scm_async_clock): Redundant declaration removed.
1832 * continuations.c (scm_dynthrow): Redundant declaration removed.
1834 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
1835 Definition typos corrected.
1837 * debug.h: Missing declarations of functions in debug.c added
1840 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
1841 Missing declarations to functions in eval.c added.
1843 * filesys.c: Possibly uninitialized variable rv.
1845 * gc.h (scm_object_addr, scm_unhash_name): Missing
1846 declarations of functions defined in gc.c added.
1848 * genio.c: Possible typos str_data -> wstr_data. ???
1850 * genio.c: Possibly unintended shadowing of local variable
1851 `int c' (gotos out of scope of inner `c'). ???
1853 * init.c: Uninitialized `SCM last' may be used.
1855 * ioext.h: (scm_sys_isatty_p): Typo.
1857 * list.h (scm_list_head): Missing prototype for function in
1860 * numbers.c (scm_two_doubles): Changed from extern to static
1861 (is used only within numbers.c).
1863 * numbers.h: Repeated declarations removed.
1865 * ports.h (scm_close_all_ports_except): Declaration for the
1866 function defined in ports.c added.
1868 * posix.h: Missing declarations added.
1870 * procs.h (scm_make_subr_opt): Missing declaration added.
1872 * socket.h (scm_sys_gethost): Missing declaration added.
1874 * socket.h: Redundant declarations removed (they are in fdsocket.h).
1876 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
1877 Missing declarations added.
1879 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
1881 * struct.c: Uninitialized variable `SCM answer' may be used.
1883 * unif.c (l2ra): Declaration prototype.
1885 * unif.c (scm_array_equal_p): Dummy definition removed (it is
1886 defined in ramap.c).
1888 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
1889 Redundant declarations removed (they are in ramap.h).
1891 * variable.h (scm_make_udvariable,
1892 scm_make_undefined_variable): Declaration corrected to
1893 correspond variable.c.
1895 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
1896 Missing declarations added.
1898 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
1900 * Makefile.in (distclean): Don't forget to delete fd.h.
1902 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1904 * fd.h.in, tags.h: Trivial cleanups.
1906 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
1907 marksweep.h just declared functions from gc.c.
1908 * gc.h, libguile.h: Don't #include "marksweep.h".
1909 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
1910 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
1911 dependencies updated.
1913 * libguile.h: Don't #include "files.h"; it's been deleted.
1915 * files.c (scm_sys_delete_file): Moved to filesys.c.
1916 File is now empty; deleted.
1918 * filesys.c: scm_sys_delete_file is now here. Remove
1919 #if's; they seem to rely on remnants of an old portability
1920 regimen. If the problems come up again, solve them properly,
1921 using autoconf. Specifically: Don't test M_SYSV, and #define
1922 remove to be unlink if it's #defined; don't use remove just
1923 because HAVE_STDC_HEADERS is #defined.
1924 * filesys.h: Add declarations for scm_sys_delete_file.
1925 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
1926 files.o, files.h, files.c, and files.x.
1927 * init.c: Don't #include "files.h", and don't call scm_init_files.
1929 Use SCM_P instead of PROTO; the latter intrudes on the user's
1931 * params.h: Deleted; definition of SCM_P moved to...
1932 * __scm.h: ... here, where it replaces PROTO macro.
1933 * libguile.h, smob.h: Don't #include "params.h".
1934 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
1935 smob.h: Fix prototypes accordingly.
1936 * Makefile.in: Update dependencies.
1937 (inner_h_files): Remove params.h.
1939 * gc.c: #include "gc.h"; every module should include its header,
1940 to let the compiler cross-check the declarations against the
1943 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
1944 simpos.h: #include "libguile/__scm.h".
1946 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
1948 * init.c: Don't forget to #include smob.h and init.h.
1949 * Makefile.in: Dependencies updated.
1951 * smob.h: Use PROTO instead of #if __STDC__.
1953 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
1955 * __scm.h: Doc fixes.
1957 * __scm.h, libguile.h: Use "quotes" in the #includes, not
1958 <angles>; this allows `make depends' to work properly.
1960 * libguile.h: #include smob.h and pairs.h before the others; they
1961 define typedefs used by other headers.
1963 C files should #include only the header files they need, not
1964 libguile.h (which #includes all the header files); the pointless
1965 recompilation was wasting my time.
1966 * Makefile.in (all .o dependency lists): Regenerated.
1967 * libguile.h: Don't try to get a definition for size_t here...
1968 * __scm.h: Do it here.
1969 * _scm.h: Since this is the internal libguile header, put things
1970 here that all (or a majority) of the libguile files will want.
1971 Don't #include <libguile.h> here; that generates dependencies on
1972 way too much. Instead, get "__scm.h", "error.h", "pairs.h",

2073 * stackchk.h: #include "libguile/debug.h",
2075 * print.h, read.h: #include "options.h", since everyone who uses
2076 either of these files will need that.
2078 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2079 anyone who uses this file will need them to define the smob
2080 printing functions. Also, get markers.h, since people will need
2081 to #define the mark functions.
2083 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2084 * ports.h: ... to here.
2086 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2087 don't rely on archaic C default type rules.
2089 * fports.h: #include "libguile/ports.h", since you need that in
2090 order to parse this.
2092 * genio.h: #include "libguile/print.h", because you need that to
2093 parse this; don't bother #including "ports.h", since print.h gets
2096 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2098 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2099 this; it's now a reference to an element of *scm_root.
2101 * debug.h: Don't #include "options.h"; the compiler won't be able
2102 to find that once the headers are installed; instead, #include
2103 "libguile/options.h".
2104 * gc.h: Same, with marksweep.h.
2105 * mbstrings.h: Same, with symbols.h.
2106 * scmhob.h: Same, with _scm.h.
2107 * smob.h: Same, with params.h.
2109 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2110 C files; there's no need for this, and it forces recompilations
2113 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2115 * error.c (scm_error): declare scm_error_callback.
2117 * error.h: prototype for scm_error_callback.
2119 * __scm.h: define lgh_error.
2120 (SCM_SYSERROR): redefine using lgh_error.
2122 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2124 * error.c (scm_error): new procedure.
2126 * error.h: prototype for scm_error.
2128 * Makefile.in (install): install scmconfig.h from the current
2129 directory, not $(srcdir).
2131 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2133 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2134 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2135 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

2141 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2142 vports.h, weaks.h: #include "libguile/__scm.h", not
2143 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2144 dependencies are within libguile properly.
2146 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2148 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2149 when scmconfig.h doesn't exist.
2151 * load.c (scm_sys_try_load): Correct spelling.
2153 * feature.c (scm_loc_features): Make this static.
2155 * Makefile.in (libpath.h): Omit trailing slash from path. We
2156 shouldn't require it of users, so why put it here?
2158 Move code to initialize and search %load-path from ice-9 to C
2159 code, so we can use the load-path to find the ice-9 boot code;
2160 this makes it easier to run Guile without installing it. See
2161 corresponding changes in guile/Makefile.in.
2162 * feature.c: Move stuff concerned with the load path to load.c.
2163 (scm_compiled_library_path): Deleted.
2164 Don't #include libpath.h here.
2165 * feature.h: Don't mention scm_compiled_library_path.
2166 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2167 <sys/stat.h>, and <unistd.h> (if present).
2168 (R_OK): #define if the system hasn't deigned to.
2169 (scm_loc_load_path): New variable.
2170 (scm_init_load_path, scm_sys_search_load_path,
2171 scm_sys_try_load_path): New functions.
2172 (scm_init_load): Initialize scm_loc_load_path to point to the
2173 value cell of the Scheme %load-path variable.
2174 * load.h: Add declarations for scm_sys_search_load_path,
2175 scm_sys_try_load_path.
2176 * init.c: Call scm_init_load_path.
2177 * Makefile.in (feature.o, load.o): Dependencies updated.
2179 * load.c, load.h: Rewrite using PROTO macro.
2181 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2183 * gc.c (scm_cellp): New function: C predicate to determine if an
2184 SCM value can be regarded as a pointer to a cell on the heap.
2186 * gc.h: Added declaration of scm_cellp.
2188 * gdb_interface.h: New file: The GDB interface header from the GDB
2191 * gdbint.c: New file: GDB interface.
2193 * gdbint.h: New file: GDB interface.
2195 * libguile.h: Added #include <libguile/gdbint.h>.
2197 * init.c (scm_boot_guile): Added scm_init_gdbint.
2199 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2200 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2201 found if object files and source are kept separate).
2203 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2205 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2207 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2209 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2210 TK_SRC_DIR; they're not relevant any more.
2212 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2213 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2215 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2217 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2218 search path, so we can find the <libguile/MUMBLE.h> headers.
2220 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2222 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2223 implicit in the .c.o rule.
2224 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2227 Put the library path in a header file, instead of passing it on
2228 the command line in every compilation.
2229 * Makefile.in (libpath.h): New target.
2230 (feature.o): Depend on libpath.h.
2231 (clean): Delete libpath.h.
2232 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2233 * feature.c: ... #include "libpath.h" here.
2234 * .cvsignore: Ignore libpath.h.
2236 Don't install the unwashed masses of Guile header files in the
2237 main #include path; put most of them in a subdirectory called
2238 'libguile'. This avoids naming conflicts between Guile header
2239 files and system header files (of which there were a few).
2240 * Makefile.in (pkgincludedir): Deleted.
2241 (innerincludedir): New variable; this and $(includedir) are enough.
2242 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
2243 (installed_h_files): Divide this up. Now this variable lists
2244 those header files which should go into $(includedir) (i.e. appear
2245 directly in the #include path), and ...
2246 (inner_h_files): ... this new variable says which files appear in
2247 a subdirectory, and are referred to as <libguile/mumble.h>.
2248 (h_files): List them both.
2249 (install): Create innerincludedir, not pkgincludedir. Put
2250 the installed_h_files and inner_h_files in their proper places.
2251 (uninstall): Corresponding changes.
2252 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2253 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2254 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
2255 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,

2259 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2260 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2261 vports.h, weaks.h: Find __scm.h in its new location.
2262 * __scm.h: Find scmconfig.h and tags.h in their new locations
2263 (they're both "inner" files).
2265 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
2267 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
2269 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2271 * posix.c: Doc fixes.
2273 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
2275 * socket.c: Don't include a prototype for inet_aton; just use a
2276 K&R style declaration, to avoid warnings but minimize the chance
2277 of conflicts with the system.
2279 On NextStep, <utime.h> doesn't define struct utime, unless we
2280 #define _POSIX_SOURCE before #including it.
2281 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
2282 * acconfig.h: New comment text for above CPP symbol.
2283 * configure.in: Call it.
2284 * posix.c: #define _POSIX_SOURCE if it seems necessary.
2286 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
2288 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
2289 testing for __EMX__.
2291 * posix.c: #include <libc.h>, if it exists.
2293 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
2294 don't even know if the latter exists.
2296 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
2297 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
2298 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
2300 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
2302 (scm_init_posix): Use them when initializing the Scheme constants
2305 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2307 * Makefile.in (libdir, includedir, bindir): Use the
2308 autoconf-supplied values, instead of deriving them ourselves.
2309 (pkgincludedir, datadir, pkgdatadir): New variables.
2310 (install, uninstall): Put the header files in a special
2311 subdirectory, not in the main search path.
2313 * Makefile.in (ALL_CFLAGS): Provide the proper value for
2314 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
2316 * Makefile.in (IMPLPATH): Deleted; never used.
2318 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
2319 on the Tcl/Tk source any more.
2320 (INCLUDE_CFLAGS): Remove references to the above.
2322 * Makefile.in (version.o): Corrected dependencies.
2324 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
2326 * libguile.h: #include "version.h"
2328 * init.c (scm_boot_guile): Call scm_init_version.
2329 * gscm.c (gscm_run_scm): Call scm_init_version.
2331 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
2332 GUILE_VERSION): AC_DEFINE these.
2333 (acconfig.h): #undef the above symbols.
2335 * Makefile.in (libobjs): Add version.o.
2336 (installed_h_files): Add version.h.
2337 (c_files): Add version.c.
2338 (gen_c_files): Add version.x.
2339 (version.o): New rule.
2340 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
2341 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

2350 weaks.o): Add version.h to dependency lists.
2351 (markers.o): Remove duplicate rule.
2353 * version.h: New file.
2355 * version.c: New file.
2357 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2359 * symbols.c (scm_strhash): scm_downcase is now a function, not an
2360 array; use it appropriately. Since GCC is quite happy to
2361 subscript functions, it never warned us about this; we should use
2362 -Wpointer-arith in the future. I guess we never tested
2365 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2367 * socket.c: Doc and copyright fixes.
2369 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2371 * debug.c: Fixed and improved gdb support.
2373 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2375 * socket.c: Added declaration of inet_aton to avoid compiler
2376 warning. (Hope this solution is correct.)
2378 * stime.c: Added declaration of ftime. (This is missing in
2381 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
2383 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2385 * Makefile.in (c_files): add strerror.c.
2387 * strerror.c: new file from Emacs' sysdep.c.
2388 maybe configure should also check for sys_errlist.
2390 * configure.in (AC_REPLACE_FUNCS): add strerror.
2392 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2394 * debug.c (scm_init_debug): Added initialization for
2395 scm_evaluator_traps.
2397 * debug.h, debug.c: Various name changes.
2398 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
2399 "debug-options-interface". See commentary in options.c.
2401 * options.h, options.c: Options now have documentation strings.
2402 Also added a long explanatory commentary.
2404 * eval.c, print.h, print.c, read.h, read.c: Modifications to
2407 * gscm.c, init.c, root.c, throw.c: Bug fixes:
2408 last_debug_info_frame is now updated in all cases.
2410 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
2413 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2415 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
2416 Added option STACK_CHECKING.
2418 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
2420 * Makefile.in: Added {debug,options,srcprop}.{h,c}
2422 * __scm.h: Removed symbols for debugging support.
2424 * acconfig.h: Added symbols for debugging support.
2426 * configure.in: Added user option for debugging support.
2427 --enable-debug will include the debugging code into libguile.a.
2429 * continuations.c (scm_make_cont): Enlarged the #if 0 around
2430 scm_relocate_chunk_to_heap.
2432 * debug.c: New file: low-level debugging support. It also
2433 includes support for debugging with gdb. (The extensions to gdb
2434 are written by Per Bothner at Cygnus.)
2436 * debug.h: New file: low-level debugging support.
2438 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
2439 argument pairs. Extensive modifications to the debugging
2440 evaluator. Added "SECTION:" commentaries to clarify what happens
2441 when, during double compilation. Renamed EVALIMP --> EVALIM.
2442 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
2443 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
2444 the beginning of the file. New procedure: scm_unmemocopy.
2445 Added some global state variables needed by the debugging
2446 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
2447 check_entry, check_apply, check_exit, debug_options and
2448 evaluator_traps. New acro: undefine.
2450 * eval.h: Renamed EVAL --> XEVAL.
2452 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
2453 --> scm_make_weak_key_hash_table.
2455 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
2456 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
2458 * libguile.h: Conditionally include debug.h
2460 * objprop.c (scm_object_properties, scm_set_object_properties_x):
2461 scm_object_properties shouldn't return handle. `handle' now gets
2462 initialized in scm_set_object_properties_x. scm_object_properties
2463 doesn't any longer create an entry in scm_object_whash.
2465 * options.c: New file: handling of run time options.
2467 * options.h: New file: handling of run time options.
2469 * posix.c (scm_getpgrp): Cast pointer to getpgrp.

2490 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2492 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
2494 * libguile.h: #include "objprop.h"; I guess this was forgotten.
2496 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
2497 and should be called by the final client.
2499 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
2501 * gc.h: Use the PROTO macro when declaring functions.
2502 * gc.c: Use the PROTO macro when declaring static functions.
2503 Remove the CPP hair around function definitions.
2505 * gc.c (scm_init_storage): Initialize scm_asyncs.
2507 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
2508 preprocessor symbol; "__scm.h" is where it might get #defined.
2509 * __scm.h: Similar: #include <scmconfig.h> before testing
2512 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
2514 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
2516 * init.c (scm_boot_guile): Add init_func argument; call
2517 (*init_func) instead of calling scm_appinit; it's ucky to
2518 hard-code names for the user's procedures.
2519 * init.h (scm_boot_guile): Adjust declaration.
2521 * __scm.h (PROTO): New macro, for declaring functions with
2524 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
2525 eliminate all the __STDC__ conditionals.
2526 (scm_boot_guile): Add declaration.
2527 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
2528 Remove __STDC__ conditionals around function definitions; the
2529 declarations in init.h will provide the same information, more
2532 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
2533 complain about it in the error message; the error message is
2534 adequate without that note, and there's nothing the user can do
2537 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
2539 * Makefile.in (ancillary): Drop def.sed.
2541 * posix.c (scm_init_posix): Use numeric values, rather than
2542 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
2543 F_OK. The symbols aren't available on some systems, and I'm
2544 pretty sure their values are fixed by common widespread practice.
2545 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
2547 More functions unavailable on some systems.
2548 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
2549 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
2551 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2552 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
2553 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
2554 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
2555 stub that signals an error as the #else.
2557 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
2559 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
2561 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
2563 * unif.c: include ramap.h.
2565 * read.c (endif): case_insensative_p renamed case_insensitive_p.
2567 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
2569 * ports.c: include sys/ioctl.h.
2571 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
2573 * configure.in: check for sys/ioctl.h.
2575 * ports.c: include <malloc.h> not "malloc.h".
2577 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2579 * fports.c: remove ttyname and tmpnam declarations.
2581 * posix.c: fewer ttyname declarations.
2583 * fports.c: include <string.h> not "string.h".
2585 * init.c, ioext.c: include string.h and unistd.h.
2587 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2589 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
2590 genio.c, simpos.c, vports.c: include string.h.
2592 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
2594 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
2596 (scm_addr_buffer_size): change type from scm_sizet to int.
2597 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
2598 from scm_sizet to int.
2600 * error.c: include unistd.h.
2602 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
2605 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
2607 * __scm.hd, def.sed: deleted.
2609 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
2611 Changes for NeXT, suggested by Robert Brown.
2612 * configure.in: Call AC_TYPE_MODE_T.
2613 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
2614 NeXT. Put header file list in alphabetical order.
2615 * configure, scmconfig.h.in: Regenerated.
2616 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
2618 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
2621 * acconfig.h: New file, providing documentation for the CPP
2622 symbols defined in configure.in
2623 * acconfig-1.5.h: Removed; superceded by the above.
2625 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
2627 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
2629 * fports.c (scm_open_file): don't return #f, throw error.
2631 * ioext.c (fileno): renamed from %fileno.
2632 (soft-fileno): deleted.
2634 * ports.c (scm_port_revealed): don't need to check for -1 from
2636 (scm_set_port_revealed_x): return unspecified, not #f.
2638 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
2640 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
2642 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
2644 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
2646 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2648 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
2649 This is necessary on Ultrix, and doesn't hurt portability.
2651 * Makefile.in (dist-dir): New target, implementing a new dist system.
2652 (installed_h_files): Put in alphabetical order.
2653 Remove duplicate entries for markers.h and unif.h.
2654 (c_files): Remove duplicate entries for markers.c.
2655 (ancillary): Renamed from anillery; all uses changed. Remove
2656 PLUGIN; it's a directory, and needs special treatment in dist-dir.
2657 Remove all the ../doc/* files; doc/Makefile.in handles that.
2659 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
2661 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
2662 every if must have an else, or else the whole command has a
2663 non-zero exit code whenever the if's condition is false.
2665 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
2667 * posix.c: include string.h.
2669 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2671 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
2674 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
2675 Remove leading % from scheme names.
2676 Do not return error values, call SCM_SYSERROR or similar.
2678 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
2680 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
2682 * struct.c (scm_init_struct): new file.
2684 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
2686 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
2687 (scm_list_head): added list-head for rapidly chopping argument
2688 lists off of longer lists (and similar).

2693 handle for obj, not the handle itself.
2695 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
2697 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
2698 weak hash tables last of all marking to avoid an obscure gc bug.
2699 WARNING: circular lists stored in a weak hash table will hose us.
2701 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
2703 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
2704 new functions similar to scm_substring_move_left_x and
2705 scm_substring_move_right_x.
2707 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
2709 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
2712 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
2714 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
2716 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
2718 * strports.c (scm_strprint_obj): convenience function. C for
2719 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
2721 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
2722 removed to a separate library
2724 * init.c (scm_boot_guile): copied from guile-tcl.c.
2725 Initialization specific to tcl interpreters removed.
2727 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
2729 * ports.c (scm_ports_prehistory): size malloced here doesn't
2730 matter so long as it is non-0 (got rid of "* 4").
2732 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
2734 * gscm.h: gscm_mkarray eliminated (presumably was not being used
2735 since its definition was bogus).
2737 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
2739 * mallocs.[ch]: back again (for rx at least).
2741 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
2743 * ports.c: removed functions relating to the mapping between ports
2744 and descriptors. (That stuff is unix-specific and should be collected
2745 in a separate library).
2747 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
2748 (Tom Mckay@avanticorp.com)
2750 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
2752 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
2753 handled correctly (SCM_FREEP was applied to them) -- test for
2754 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
2755 being overwritten with #f. (brown@grettir.bibliotech.com)
2757 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>

2787 NOTE: don't use a alist here.
2788 (scm_set_procedure_properties_x): fix type checking throughout this file.
2790 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
2792 * ports.c (scm_remove_from_port_table): adjust scm_mallocated

2798 * vports.c (scm_make_soft_port): allocate a port table entry
2799 (possibly triggering gc) before setting the tag of the corresponding
2802 * pairs.c (scm_delq_x): never throw an error.
2804 * vectors.c (scm_make_vector): made the default vector fill argument
2805 into '() (much more useful than the previous value, "#unspecified")
2807 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
2809 * ports.c (scm_add_to_port_table): Added fields
2810 to port table entries: file_name, line_num, col.
2811 Update these in open_file, gen_getc and gen_ungetc.
2812 Added procedures to access those fields.
2814 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
2816 * procs.c (scm_make_subr_opt): new entry point for making
2819 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
2821 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
2823 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
2825 * numbers.c (scm_exact_p): This function no longer
2826 implements "integer?".
2828 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
2830 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
2831 (scm_gc_stats): return an assoc of useful data. Replaces "room"
2832 and the stats reporting formerlly built into repl.
2834 * repl.[ch]: removed.
2835 GC statistics keeping moved to gc.c.
2836 Other statistics keeping can be done from Scheme.
2837 REPLS are now written in Scheme.

2848 * feature.c (scm_compiled_library_path): moved here from repl.c.
2849 This file is for stuff relating specifically to Scheme libraries
2852 * eval.c (scm_m_define): don't give warning about redefinition, don't
2855 NOTE: this should throw a resumable exception with parameters --
2856 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
2858 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.

2876 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
2879 * strports.c: don't reveal the port's string to the caller
2880 because it changes size.
2882 (stputc stwrite): check/change the strings length with interrupts
2885 * objprop.c (scm_set_object_property_x &c): use the generic
2886 hashing functions and be threadsafe.

2889 (per suggestion jaffer@gnu.ai.mit.edu).
2891 * mbstrings.c (scm_multi_byte_string): guard against argument list
2894 * strings.c (scm_make_string): loop cleanup

2922 initialization to fix a race condition.
2924 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

2948 set the multi_byte flag correctly in symbols. This is wrong.
2949 intern_obbary_soft and msymbolize should take an extra parameter.
2950 Also, weird multibyte symbols don't print correctly.
2951 The weird symbol syntax is also a bit bogus (emacs doesn't quite
