1 Fri Feb 28 22:12:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3 * procs.c: Introduce the existent C function scm_thunk_p at the
6 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
8 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
9 used from C to easily lookup the value of a symbol in the current
12 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
14 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
15 scm_init_unif in this file. This will also fix a previous problem
18 * configure.in: Added AM_MAINTAINER_MODE
20 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
22 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
25 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
27 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
28 source files that are not always included in libguile but should
29 have their dependencies calculated by automake. This variable is
30 recognized by automake, no further magic is needed.
31 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
32 to deal exclusively with *.lo files, as it seems. The *.o files
33 are built automatically when the corresponding *.lo file gets
36 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
38 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
41 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
43 * unif.c (scm_array_set_x): minor change to argument error checking.
45 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
47 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
48 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
49 They should only be included in the library at configure.in's
51 (libguile_la_LDADD): Include the appropriate .lo files here.
52 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
53 so we know when to build them (and their .lo bretheren).
54 * configure.in (LIBLOBJS): New substituted variable. We let
55 configure decide which .o files to include in LIBOBJS, and then
56 put the corresponding list of .lo files in LIBLOBJS. The latter
57 is what we pass to libtool.
58 * Makefile.in, configure: regenerated.
60 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
62 * symbols.c (scm_sysintern0): New function. Contains the core of
63 old scm_sysintern but doesn't take a second value argument.
64 (scm_sysintern): Now uses scm_sysintern0.
65 (scm_sysintern_no_module_lookup): Renamed to
66 scm_sysintern0_no_module_lookup and doesn't take a second value
69 * symbols.h (scm_sysintern0: Added declaration.
71 * options.c (scm_init_opts): Use scm_sysintern0 instead of
72 scm_sysintern when interning option keys. Otherwise we risk
73 destroying the values of already interned variables.
75 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
76 scheme-level boolean (use SCM_NFALSEP).
78 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
80 (scm_backtrace): New function. (C version of old function from
81 boot-9.scm) Motivation: Make it possible to display backtraces
82 without depending on boot-9.scm. (I'm uncertain if this
83 motivation is good enough...)
85 * root.h (scm_root_state): Add member the_last_stack_var.
86 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
88 * root.c (mark_root): Mark scm_the_last_stack_var.
90 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
93 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
95 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
96 1. mark_lazy_catch didn't mark the smob.
97 2. Both functions above have standard variants:
98 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
99 free_lazy_catch --> scm_free0.
101 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
103 * throw.c (scm_internal_lazy_catch): New function.
104 (scm_lazy_catch): Rewritten to use it.
105 (scm_ithrow): Handle the new lazy catch representation.
106 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
107 that doesn't have a jmpbuf is a lazy catch clause.
108 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
109 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
110 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
112 (scm_init_throw): Register the new lazy-catch smob type.
113 * throw.h (scm_internal_lazy_catch): decl for new function.
115 * throw.c (scm_internal_catch): Doc fixes.
117 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
118 configure.in. Including this might cause problems if applications
119 that link against libguile include their own copies of alloca, but
120 if they're using autoconf, they should be adding libguile to LIBS
121 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
122 the copy in libguile, and things will be okay. (I think.)
124 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
126 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
128 strop.h: move prototypes too.
130 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
132 * posix.c (scm_init_posix): don't intern EINTR since it's now done
135 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
136 etc. I deleted them from filesys.c long ago, but didn't
137 notice they were here too (although ineffective since
138 sys/stat.h wasn't included).
140 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
142 * eval.c: Don't define alloca in GCC case. gcc will automatically
143 use __builtin_alloca if appropriate.
145 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
147 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
148 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
149 that values of automatic variables are preserved. See comments
150 for safe_setjmp for details.
152 Change from Thomas Morgan:
153 * variable.c: Include eq.h.
154 (var_equal): New function.
155 (variable_smob): Use var_equal as the discriminator for variables.
157 * throw.c (s_throw): Remove extraneous declaration.
159 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
160 * eval.c: Add necessary CPP cruft to support that.
161 * configure, Makefile.in, scmconfig.h.in: regenerated.
163 Change from Thomas Morgan:
164 * procprop.c (scm_procedure_properties): Convert the Scheme
165 boolean returned by scm_procedure_p into a C boolean before using
166 it as a condition for SCM_ASSERT.
167 (scm_procedure_property): Likewise.
169 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
170 indications of Unixness.
173 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
175 * * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
177 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
179 * read.c (scm_lreadr): use scm_misc_error to improve one of the
180 "unknown # object" error messages.
182 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
183 (scm_i_index) and declare it static. Add a 'direction' argument
184 to indicate what way the search should go.
185 (scm_i_index): throw out-of-range error instead of wrong-type-arg
187 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
188 strop.h: remove scm_i_index, scm_i_rindex prototypes.
190 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
192 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
194 * * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
195 to avoid clash with various scsh forks.
197 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
199 The following two changes (ramap.c, throw.c) are motivated by the
200 apparent unportability of forward declarations of static arrays of
201 the form `static foo bar[];'.
203 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
204 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
206 * throw.c (scm_throw): Moved above scm_ithrow.
208 * options.h: Removed the extern declarations of scm_yes_sym and
209 scm_no_sym since these are static.
211 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
213 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
215 * Makefile.am: remove AWK=@AWK@.
216 Add a rule for generating errnos.list.
217 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
219 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
220 don't extract errnos, just set a variable (avoids the
221 need to recompile error.c just because configure is run.)
223 * unif.h: update prototypes.
224 * unif.c (scm_uniform_array_read,write): change the offset and
225 length arguments to start and end, for consistency.
227 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
229 * ioext.h: update prototypes.
230 * * ioext.c (scm_read_delimited_x): replaces scm_read_line and
231 scm_read_line_x, it's a more general procedure using an
232 interface from scsh. read-line and read-line! are now defined
234 * Note that the new read-line trims the terminator
235 by default, previously it was appended to the returned string. An
236 optional argument specifies how to process the terminator (scsh
237 compatible). For the old behaviour: (read-line port 'concat).
238 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
239 returns a pair, but is converted to multiple values if the scsh
242 socket.h: update prototypes.
243 * socket.c (scm_recvfrom): for consistency with other procedures,
244 take start and end as separate optional arguments.
245 * (scm_recv, scm_recvfrom): don't allow the second argument
246 to be a size, only a buffer. Change the scheme names to
247 recv! and recvfrom!. Don't return the buffer.
249 * ioext.h, posix.h: move prototypes too.
250 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
251 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
252 "read.h" and "unif.h".
253 * ioext.c: include "chars.h"
255 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
257 * dynl.c: The dynamic linking and module registration functions
258 are now defined even when dynamic linking is not available for the
259 host system. Some of their functionality can be done without
260 dynamic linking; when it's really needed, they throw errors.
262 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
264 * configure.in: Only define DYNAMIC_LINKING when one of the system
265 dependent functions is detected.
266 * dynl.c (scm_dynamic_func): New function to get the address of a
267 function in a dynamic object.
268 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
269 produced by scm_dynamic_func as the thing to call.
271 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
273 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
274 (scm_register_module_xxx, scm_registered_modules,
275 scm_clear_registered_modules): New functions.
277 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
279 * symbols.c (scm_sysintern): Renamed to
280 scm_sysintern_no_module_lookup.
281 (scm_sysintern): New function to take the place of the old
282 scm_sysintern. It uses the current toplevel lookup closure to give
283 the symbol its value. This is a temporary hack to put packages
284 like gtcltk into their own module.
285 (scm_can_use_top_level_lookup_closure_var): New variable to tell
286 us whether `scm_top_level_lookup_closure_var' has been initialized
288 * eval.c (scm_init_eval): Set it.
290 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
292 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
293 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
295 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
297 * (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
298 scm_sys_dup): deleted: FD capability will be added to other
300 * Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
301 scm_fd_free, fd_smob, scm_intern_fd.
302 * (scm_open): renamed from scm_sys_open. Return a port instead of
303 an FD object. Make the mode argument optional.
304 * (scm_sys_create): deleted, it's just a special case of open.
305 (scm_init_filesys): move interning of constants O_CREAT etc.,
306 here (were previously using SCM_CONST_LONG macro).
307 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
309 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
310 include "fports.h" and <stdio.h>
311 (scm_stat, scm_select): don't support FD objects.
313 * error.h: adjust scm_syserror_msg prototype.
314 * error.c (scm_syserror_msg): take an extra argument for errno.
315 Using the global value didn't always work, since it could be
316 reset by procedure calls in the message or args arguments.
318 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
319 I don't understand why the check was there (and what about the
322 * strop.c (scm_string_copy): allow shared substrings to be copied.
324 * unif.h: corresponding change to prototypes.
325 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
326 recognize two new optional arguments: offset and length. Allow
327 the port argument to be an integer (file descriptor, for scsh).
328 Include <unistd.h> for "read" prototype.
330 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
332 * socket.c: don't include filesys.h.
334 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
336 * Makefile.am: add AWK=@AWK@ (?)
338 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
340 Add a rule to generate errnos.c from errnos.
341 * error.c (scm_init_error): include errnos.c.
342 * errnos_cnvt.awk: new file, converts the list of errno codes to
344 * errnos_get.c: new file.
345 * errnos.default: new file, contains errnos to try if they can't
346 be extracted from errno.h.
347 * configure.in: if using GCC, try and extract errno codes from
351 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
353 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
354 * Makefile.am: Made libguile into a libtool library.
355 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
356 Set libtool_libs to indicate that libguile is a libtool library.
357 See guile/ChangeLog for details.
358 * .cvsignore: ignore "*.lo", the libtool library objects.
360 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
362 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
363 use htons in getservbyport argument.
365 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
367 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
368 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
371 * objprop.c (scm_object_property): No need to take the CDR of the
372 value returned by scm_object_properties, since Aug 20 change.
374 * configure.in: When checking for struct linger, #include
375 <sys/types.h> as well as <sys/socket.h>. I've never known
376 <sys/types.h> to cause any portability problems, and Solaris's
377 <sys/socket.h> needs it.
378 * configure: Rebuilt.
380 I think the Sun compiler has chosen a perverse way to interpret
381 ANSI declarations combined with K&R definitions. We'll
382 appease it a little bit. But when it invades France, we fight.
383 * print.c (scm_iprlist): Change 'tlr' argument to an int.
384 * print.h (scm_iprlist): Here too.
385 * numbers.c (scm_divbigdig): Change definition to match
386 declaration in numbers.h.
387 * unif.c (scm_makflo): Change definition to match declaration in
390 * init.c (scm_boot_guile): Don't return the value of
391 scm_boot_guile_1. This function doesn't return a value;
392 scm_boot_guile_1 doesn't return a value (or return at all).
394 * eval.c (unmemocopy): Add a semicolon to appease the Sun
397 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
398 compile. I have a feeling this function is a bad idea anyway ---
399 one should always test for features, not systems.
401 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
402 semicolons. Only pure luck kept this from being noticed earlier.
404 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
406 * socket.c (scm_recvfrom): Added missing semicolon.
408 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
410 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
411 the buffer and start and end positions for scsh networking
414 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
416 * configure.in: Revert previous change to this file; the problem
417 is due to transient automake weirdness.
418 * configure: Rebuilt.
420 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
421 PLUGIN/guile.libs. configure generates the latter from the former.
422 * Makefile.in: Rebuilt.
424 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
425 need this if we install scripts, like guile-snarf.
426 * configure: Rebuilt.
428 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
430 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
432 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
434 * socket.c (scm_addr_vector): fix faulty scm_listify.
436 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
438 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
439 style block comment is no longer considered an error.
441 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
443 * PLUGIN/guile.libs.in: New file.
444 * PLUGIN/guile.libs: Removed from repository.
445 * configure.in: Create PLUGIN/guile.libs from
446 PLUGIN/guile.libs.in. This is for including additonal libraries
447 needed for dynamic linking.
448 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
449 instead of PLUGIN/guile.libs.
451 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
453 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
455 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
456 occurrences of the given element from the list, not just the
457 first. This is how the Emacs Lisp functions behave, how the
458 analogous Common Lisp functions behave, and (I believe) how the
459 older Maclisp functions worked. I realize that this change may
460 break code, but it seemed better to break it before the Guile
463 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
464 Their prototypes were already present in gc.h, but they weren't
466 (scm_init_storage): Initialize scm_protects.
467 * root.c (scm_protects): New element of scm_sys_protects.
469 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
471 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
473 * libguile.h: Added #include "libguile/net_db.h".
475 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
476 30 change. That file is only meant for communication between the
477 configuration process and load.c. If code linked against libguile
478 wants to get at the paths mentioned in libpath.h, it can call
479 functions declared in load.h.
481 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
483 * libguile.h: Removed #include "libguile/fdsocket.h"
485 * net_db.c: Added #include <sys/socket.h>.
487 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
489 * filesys.c (scm_input_waiting_p): use select in preference to
490 FIONREAD, since the latter doesn't detect EOF.
491 Throw error if neither select nor FIONREAD available.
493 * socket.c (scm_connect): take a port, not a fd object.
494 (scm_fill_sockaddr): throw an error if fam is not recognised.
495 (scm_bind): use scm_fill_sockaddr.
496 (scm_listen): take a port, not a fd object.
497 (scm_accept): take and return a port. return #f in the car if
499 (scm_sock_fd_to_port): new procedure.
500 (scm_socket): use scm_sock_fd_to_port.
501 (scm_addr_vector): throw error if unrecognised address type.
502 take an extra argument with the calling procedure name.
503 (scm_getsockname): take a port. return #f if address can't be got.
504 (scm_getpeername): take a port. return #f if address can't be got.
505 (scm_recvfrom): take a port. return #f for address component if can't
507 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
508 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
510 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
512 * throw.c (scm_internal_catch): Make body funcs and handler funcs
513 use separate data pointers, to allow them to be designed
514 independently and reused.
515 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
516 Renamed from catch_body, catch_handler, and uncaught_throw; made
518 (struct scm_catch_body_data): Renamed from catch_body_data; moved
520 (scm_catch): Use the above.
521 (scm_throw): Don't bother printing a message for an uncaught
522 throw; we establish a default handler in init.
523 * throw.h (scm_internal_catch): Prototype updated.
524 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
526 (struct scm_body_thunk_data): New structure, used as data
527 argument to scm_body_thunk.
528 * init.c (struct main_func_closure): New structure, packaging up
529 the data to pass to the user's main function.
530 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
531 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
532 scm_internal_catch to establish a catch-all handler, using
533 scm_handle_by_message. This replaces the special-case code in
535 (invoke_main_func): Body function for scm_internal_catch; invoke
536 the user's main function, using the main_func_closure pointer to
537 decide what to pass it.
538 * root.c (struct cwdr_body_data): Remove handler_proc member.
539 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
540 (cwdr_handler): Removed.
542 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
544 * socket.h (SCM_P): update bind prototype.
545 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
547 (scm_socket): return a port, not a file descriptor object.
548 include "fports.h" and <unistd.h>
549 (scm_bind): take a port, not a file descriptor object.
550 take an extra argument for address args.
552 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
553 INADDR_NONE, INADDR_LOOPBACK.
555 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
557 * init.c: include net_db.h and not fdsocket.h.
558 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
560 * Makefile.am: corresponding changes.
561 * socket.h: renamed from fdsocket.h, fix names.
562 * net_db.h: renamed from socket.h, fix names.
563 * socket.c: renamed from fdsocket.c.
564 remove _sys from procedure names.
565 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
566 add "socket" to features list.
567 * net_db.c: renamed from socket.c.
568 remove _sys from procedure names.
569 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
570 add "net-db" to features list.
571 include "net_db.h". don't include <sys/socket.h> or
574 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
576 * tags.h (scm_tags): Removed comma at end of last enumerator.
578 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
580 Don't use GCC extensions to allocate space for debugging frames.
581 (Here he goes again! Why do we put up with this?!)
582 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
583 an scm_debug_info structure, not an in-line array of them. Add
584 'info' member, to say how many vect elements we've used, for eval
586 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
587 a new variable debug_info_end to mark the end of vect, instead of
588 the address of the 'info' pointer itself.
589 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
590 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
591 (SCM_APPLY): Explicitly allocate space for debug.vect.
592 * debug.c (scm_m_start_stack): Same, for vframe.vect.
593 * stacks.c: Adjusted for new debug frame structure.
594 (RELOC_INFO, RELOC_FRAME): New macros.
595 (stack_depth, read_frames): Use them, and new scm_debug_frame
596 element 'info', instead of magically knowing that eval frames have
597 an info pointer sitting after vect.
598 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
600 (scm_init_stacks): Formatting tweaks.
602 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
604 Give GCC more control flow information, so it can be sure that
605 variables aren't used uninitialized.
606 * error.h (scm_error, scm_syserror, scm_syserror_msg,
607 scm_sysmissing, scm_num_overflow, scm_out_of_range,
608 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
609 scm_misc_error): Tell GCC that these functions never return.
610 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
611 out the field type, call abort if SCM_ASSERT returns, to placate
613 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
614 scm_wta ever returns. We can't handle this case anyway, and this
615 gives the optimizer more information.
616 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
617 scm_wta ever returns.
619 In some cases, the code is fine, but GCC isn't smart enough to
620 figure that out; this usually happens when one variable is only
621 initialized and used when a particular condition holds true, and
622 we know that condition will never change within a given invocation
623 of the function. In this case, we simply initialize the variables
624 to placate the compiler, hopefully to a value which will cause a
625 crash if it is ever actually used.
626 * print.c (scm_iprin1): Initialize mw_pos.
627 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
628 * throw.c (scm_ithrow): Initialize dynpair.
629 * unif.c (scm_uniform_vector_ref): Initialize cra.
630 * struct.c (init_struct): Initialize prot.
631 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
633 * strports.c (scm_eval_0str): Don't return uninitialized garbage
634 if EXPR contains no expressions.
636 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
638 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
639 cause an infinite loop (???). So much for the algebraic
640 equivalency of variable-sized arrays and alloca...
642 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
644 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
645 a SCM boolean, not a C boolean.
647 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
649 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
650 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
651 rules for raising scm_mtrigger. Previously, unfortunate but not
652 unlikely circumstances could result in almost constant invokation
653 of the gc. Now, this situations should be less likely, but they
654 are not prevented completely.
656 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
658 * numbers.c (scm_fuck): Procedure removed; looks like old test
660 * numbers.h: Prototype removed.
662 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
664 * debug.h (scm_debug_frame): Change `vect' member from an in-line
665 array to a pointer, to match my Nov 21 change in eval.c.
667 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
669 * libguile.h: Added #include "libguile/backtrace.h", #include
672 * strings.c (scm_string scm_make_string scm_string_ref
673 scm_string_set_x scm_string_equal_p scm_string_append):
674 Bugfix according to scm patch from Aubrey Jaffer:
675 Corrected long-standing
676 (not (eqv? (integer->char 128)
677 (string-ref (make-string 1 (integer->char 128)) 0)))
678 bug found by John Kozak <jk@noontide.demon.co.uk>.
680 * strports.c, strports.h: Make scm_eval_0str return the value of
681 the last expression evaluated (previously, it returned void).
683 * strports.c, strports.h: New function: scm_read_0str. Does what
686 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
688 * simpos.c (scm_getenv): return #f if string can't be found in the
689 environment instead of throwing an exception, for compatibility
690 with numerous other systems.
692 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
694 * Makefile.am (.c.x): Use guile-snarf.
695 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
697 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
699 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
701 * backtrace.c (scm_display_error_message): Made non-static, and
702 renamed from display_error_message.
703 * backtrace.h (scm_display_error_message): Added extern decl.
704 * throw.c (uncaught_throw): Use it to display the error message.
706 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
708 * inet_aton.c: Use #if 0, not #ifdef 0.
710 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
712 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
713 to convert the returned value.
714 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
717 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
719 Add new interface to catch/throw, usable from C as well as
721 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
722 (scm_internal_catch): New function, replaces...
723 (scm_catch_apply): Deleted.
724 * throw.c (scm_catch_apply): Deleted; replaced with a more general
725 mechanism which is a bit more code, but can be used nicely from C
726 and implement the Scheme semantics as well.
727 (scm_internal_catch): This is the replacement; it's named after
728 the analogous function in Emacs.
729 (scm_catch): Reimplemented in terms of the above.
730 (struct catch_body_data, catch_body, catch_handler): New
731 functions, used by scm_catch.
732 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
733 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
734 support for new cwdr.
736 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
739 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
741 * acconfig.h: Added DYNAMIC_LINKING symbol.
742 * configure.in: Add option and checks for dynamic linking.
743 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
744 dynl.h: New files for dynamic linking support.
745 * Makefile.am (libguile_a_SOURCES):
747 (modinclude_HEADERS): Added "dynl.h".
748 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
750 * init.c (scm_boot_guile_1): Call
751 scm_init_dynamic_linking to initialize dynamic linking support.
753 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
755 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
756 (as we Schemers say). It needs to be global, so that I can tweak
757 it for the proper operation of unexec.
758 (scm_boot_guile_1_live): New variable, see above.
760 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
762 * guile-snarf.sh: Removed.
763 * PLUGIN/guile.libs: Added dependency for -lm.
764 * acinclude.m4: Renamed from aclocal.m4.
765 * PLUGIN/greet: Removed.
766 * Makefile.am, aclocal.m4: New files.
767 * configure.in: Updated for Automake.
769 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
771 * eval.c (scm_definedp): Use top_level_lookup_closure_var
772 and not top_level_lookup_thunk_var.
774 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
776 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
778 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
780 * eval.c (scm_definedp): Incompatibly changed to be a builtin
781 Scheme function, instead of syntax. Single argument is now a
784 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
786 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
787 scm_ra_divide): Properly terminate statements passed as arguments
788 to IVDEP macros. (Thanks to Bernard Urban.)
790 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
791 with non-constant sizes. (Thanks to Bernard Urban.)
793 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
795 It's an "eval closure", not an "eval thunk." A thunk is a
796 function of no arguments.
797 * root.h (struct scm_root_state): Renamed
798 top_level_lookup_closure_var from top_level_lookup_thunk_var.
799 (scm_top_level_lookup_closure_var): Renamed from
800 scm_top_level_lookup_thunk_var.
801 * root.c (mark_root): Uses changed.
802 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
803 * init.c (scm_start_stack): Uses changed.
804 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
805 Change scheme-visible name to *top-level-lookup-closure* from
806 *top-level-lookup-thunk*.
808 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
810 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
811 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
813 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
815 * gc.c (struct scm_heap_seg_data): Doc fixes.
817 * gc.c (scm_gc_sweep): Empty all segments' freelists before
818 sweeping. Then, prepend each segment's free cells to its
819 freelist, rather than wiping out the old value. (Thanks to Marius
822 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
823 scm_check_freelist, scm_debug_newcell): New functions and
824 variables, for debugging freelist problems.
825 * pairs.h (SCM_NEWCELL): New debugging version added.
826 * gc.h (scm_debug_newcell): Added extern declaration, used by
827 debugging version of SCM_NEWCELL.
829 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
831 On some systems <libc.h> conflicts with <unistd.h>, and should not
833 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
834 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
835 * configure.in: Call it.
836 * posix.c, filesys.c: Use its results to decide whether or not to
838 * configure, scmconfig.h.in: Rebuilt with autoconf and
841 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
843 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
844 pointer to the stdio stream before calling scm_setbuf0, so the
845 latter will be able to retrieve it. I'm surprised this didn't
846 segfault earlier. (Thanks to Christopher Lee.)
848 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
850 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
853 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
855 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
856 number of stack narrowing specifier pairs. The first specifier in
857 a pair controls inner border, the second the outer border. A
858 number means cut that number of frames, a procedure object means
859 cut until that object is found in operator position in a frame.
861 * root.c (cwdr): Bugfix.
863 * read.c: Recording of positions disabled by default.
865 * procs.c (scm_closure_p): New function.
867 * posix.c (scm_tmpnam): New function.
869 * load.c: Added #include "throw.h".
870 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
873 * load.c, load.h (scm_read_and_eval_x): New function.
875 * eval.c: Renamed debug option "deval" to "debug".
877 (scm_eval_x): `eval!' is no longer accessible from the scheme
878 level. Motivation: We can't allow operations which introduce
879 glocs into the scheme level. Guile's type system can't handle
880 these as data. Use `eval' or `read-and-eval!' as replacement.
882 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
883 SCM_CONSP since this is a macro!; Set vframe.prev to
884 scm_last_debug_frame instead of 0. In this way we can look
885 "above" the virtual start stack frame if we wish.
886 (scm_debug_hang): New function: Useful for debugging Guile in
887 certain tricky situations. Will probably be removed later...
889 * debug.h: Changed semantics of debug option "backtrace". This
890 option now only indicates whether we want automatic backtrace at
893 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
895 * ports.c: #include "filesys.h"
896 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
898 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
899 Motivation: This is system specific code which is related to file
900 I/O. It also may use select. Added code by Gary Houston to
901 detect presence of character in stdio buffers.
903 * libguile.h: #include "libguile/libpath.h"
905 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
906 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
907 SCM_SITE_DIR; Install libpath.h among the other include files.
909 * load.c, load.h (scm_sys_package_data_dir): New function.
911 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
913 * stacks.h: Bugfix: Don't use tail-array length field as stack
914 length field! This screwed GC.
916 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
918 * _scm.h: Added #ifndef around definition of macros min and max.
920 * __scm.h: Added hooks for threads to plugin to in ints protection
921 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
922 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
923 the main code in these macros duplicated and spread over multiple
924 files. Renamed SCM_THREADS_SWITCHING_CODE ->
925 SCM_THREAD_SWITCHING_CODE.
927 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
930 * guile-snarf.sh: New file.
931 * Makefile.in (inner_h_files): Added snarf.h
932 (ancillary, install, uninstall, distclean): Added actions for
934 (.c.x): Use guile-snarf.
935 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
936 (gen_c_files): Note that these depend on guile-snarf.
937 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
938 now in "snarf.h". Added #include "snarf.h" to get them.
939 * libguile.h: Added #include "snarf.h".
940 (Patches applied and tweaked by Jim Blandy.)
942 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
944 * socket.c: Use K&R style declaration for 'close'; the GNU coding
945 standards suggest against providing prototypes for system
946 functions. Thanks to Greg Troxel.
948 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
950 * strports.c (scm_eval_0str): New function.
951 #include "read.h", to get prototype for scm_read.
952 * Makefile.in (strports.o): Update dependencies.
953 * strports.h: New prototype.
955 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
956 scheme name from "int?" to "integer?". It seems to do the job.
957 * numbers.h: Rename prototype too.
958 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
961 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
962 scm_num_eq_p): Rename these according to R4RS conventions: call
963 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
964 to making libguile R4RS compliant without ice-9...
966 * load.c (scm_sys_search_load_path): Search for files under all
967 extensions listed in the %load-extensions variable. If FILENAME
968 is absolute, return it unchanged, without searching the load path.
969 (scm_loc_load_extensions): New variable, pointing to
970 %load-extensions' value cell.
971 (scm_init_load): Initialize it, and the value it points to.
972 (scm_primitive_load_path): Improve error reporting.
974 * load.c (scm_loc_load_hook): New variable, pointing to value cell
975 of new Scheme variable %load-hook.
976 (scm_primitive_load): Apply %load-hook to filename.
978 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
980 * configure.in: add tests for figuring out whether buffered data
981 is available in a FILE structure, which is needed by char-ready.
983 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
986 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
987 exceptions using misc_error instead of syserror. It seems a bit
988 odd to throw an exception if a string can't be found in the
989 environment, but it's consistent with open-file, stat etc.
990 (simpos.h): remove sys_ from getenv.
992 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
993 occurs, throw an error instead of returning errno. Return value
995 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
997 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
999 * filesys.c (scm_stat2scm): derive file type and permissions from
1000 the stat mode and append them to the returned vector.
1001 There isn't much overhead in doing this and it avoids the need to
1002 work with S_IRUSR et al. in Scheme.
1003 Define symbols scm_sym_regular etc.
1004 (scm_init_filesys): don't intern S_IRUSR etc.
1006 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1007 and s_primitive_load_path.
1009 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1011 * error.h: don't declare error symbols. prototype for scm_misc_error.
1013 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1016 * error.c: use SCM_SYMBOL to set up error keys.
1017 scm_misc_error: new procedure.
1019 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1021 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1022 between `#!' and `!#' is ignored.
1023 (skip_scsh_block_comment): New function.
1025 * feature.c (scm_set_program_arguments): New argument, FIRST.
1026 * feature.h: Update prototype.
1027 * init.c (scm_boot_guile_1): Pass new argument to
1028 scm_set_program_arguments.
1030 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1032 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1033 (scm_boot_guile): Call scm_set_program_arguments here, later than
1034 the old initialization.
1036 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1037 initialization procedure.
1038 - Delete in, out, err arguments; there are other perfectly good
1039 ways to override these when desired.
1040 - Delete result argument; this function shouldn't ever return.
1041 - Rename init_func argument to main_func, for less confusion.
1042 - Delete boot_cmd argument; main_func is more general.
1043 -Add 'closure' argument, to help people pass data to main_func
1044 without resorting to global variables.
1045 - Abort if reentered; don't bother returning an error code.
1046 - Call scm_init_standard_ports to set up the default/current
1047 standard ports; no need to pass them to scm_start_stack.
1048 - Remove code to evaluate the boot_cmd, and start the repl; let
1049 the user do something like that in main_func if they want.
1050 - Remove code to package up a return value; main_func can do any
1052 - Call exit (0), instead of returning.
1053 (scm_start_stack): Don't initialize the I/O ports here; that's
1054 weird. Delete in, out, err arguments. Move guts to
1055 scm_init_standard_ports, scm_stdio_to_port.
1056 (scm_init_standard_ports): New function, to set up current and
1057 default standard ports.
1058 (scm_start_stack, scm_restart_stack): Make these static.
1059 * init.h (scm_boot_guile): Adjust declaration.
1060 (scm_start_stack, scm_restart_stack): Remove externally
1061 visible declarations for these.
1062 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1064 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1065 written out several times in scm_start_stack.
1066 * fports.h: New declaration for the above.
1068 * feature.c (scm_set_program_arguments): New function.
1069 * feature.h: New declaration for the above.
1071 * ports.c: Formatting tweak.
1073 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1075 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1076 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1077 for obtaining the address of a car or cdr field. Motivation:
1078 &SCM_CXR make assumptions about the internal structure of the
1081 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1082 Motivation: see SCM_CXRLOC.
1084 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1085 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1086 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1087 Motivation: Safer use. Some other macros are defined in terms of
1088 these operations. If these are defined using the SCM_SETCXR
1089 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1090 to inefficiency and an <e1> with side-effects could potentially
1091 break. Also, these particular operations are heavily utilized in
1092 the garbage collector. In unoptimized code there will be a
1095 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1096 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
1097 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
1098 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
1099 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
1100 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1101 vports.c: Cleaned up use of pairs: Don't make any special
1102 assumptions about the internal structure of selectors and
1103 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1104 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1105 (Among other things, this change makes it easier to build Guile
1106 with certain compilers which have problems with casted lvalues.)
1108 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1110 * stacks.c: Improve selection of relevant stack frames when making
1111 a stack object. Introduce one level of indirection in the stack
1112 object to make it possible to "narrow" to a certain region of the
1113 stack. This facilitates making use of more clever algorithms (not
1114 implemented) for selecting relevant frames and gives a cleaner
1115 design since selection of frames can be done independently of
1116 extraction of frames from the real stack.
1117 (scm_stack_id): Also take #t as argument which means look at
1120 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1121 Turn n_tail into an integer directly representing current number
1122 of frames in stack. Add field tail.
1124 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1126 * debug.c (scm_make_memoized): Made it available at scheme level.
1127 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1128 SCM_NIMP before applying heavier predicates in argument checking.
1129 (scm_local_eval): Also take memoized object as argument.
1131 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1132 aren't created with zero length, but should such a strange
1133 creature suddenly turn up...
1135 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1137 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1138 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1140 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1142 * variable.c (scm_make_variable): Make the name hint optional, as
1144 (anonymous_variable_sym): Renamed from variable_sym. All uses
1147 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1148 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1149 of scm_primitive_load_path was also changed to
1150 "primitive-load-path", from "%try-load-path". Callers changed.
1151 We'd like to respect the convention that a function named
1152 "try-mumble" should behave just like the function called "mumble",
1153 but return #f instead of signalling some error.
1154 * load.h: Rename prototypes.
1156 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1158 * print.c (make_print_state, grow_print_state), print.h: Modified
1159 the print state representation: Don't use a tail array for
1160 recording of circular references. Resizing of the print state
1161 structure invalidates the print state pointer. To avoid passing
1162 around an indirect print state reference to all printing
1163 functions, we instead let the print state reference a resizable
1166 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1168 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1169 Don't crash when passed an improper list terminated by a
1170 non-immediate value.
1172 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1174 Allocate data for structures on an eight-byte boundary, as
1175 required by the tagging system.
1176 * struct.c (alloc_struct): New function.
1177 (scm_make_struct, scm_make_vtable_vtable): Call it.
1178 * struct.h (scm_struct_n_extra_words): Bump to 3.
1179 (scm_struct_i_ptr): New "field".
1180 * gc.c (scm_gc_sweep): When we need to free the data, use the
1181 information stored by alloc_struct to find the beginning of the
1182 block allocated to the structure, so we can free it.
1184 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1186 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1189 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1190 (scm_debug_info): New member: id.
1192 * stacks.c: Stacks are now represented as structs; Stacks have an
1193 id given to them by `start-stack'.
1194 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1196 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1197 Changed stack representation.
1199 * debug.c (scm_procedure_name): Try procedure property `name' for
1200 compiled closures aswell.
1202 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
1204 * eval.c: scm_i_name moved to gsubr.c
1205 (scm_m_define): Record names of all kinds of procedure
1206 objects. (Earlier, only closures were recorded.)
1208 * procprop.h: Added declaration of scm_i_name.
1210 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1211 (scm_make_gsubr): Record names of compiled closures.
1213 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1215 * debug.c, debug.h: Removed obsolete code.
1217 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1218 stacks.c: Renamed regs --> scm_contregs.
1220 * print.c (scm_free_print_state): Cleanup print state before
1221 returning it to pool. It is better to do it here than in
1222 scm_prin1 since scm_prin1 is called often.
1224 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1225 s_set_source_property_x): Check that first argument is a pair or a
1228 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1229 scm_i_line, scm_i_column and scm_i_breakpoint global.
1231 * init.c: Added #include "backtrace.h" and #include "stacks.h".
1232 (scm_boot_guile_1): Added calls to scm_init_backtrace and
1235 * debug.h: Added debug object smob declaration and macro
1238 * configure.in: Build with backtrace.o and stacks.o if debug
1241 * Makefile.in: Added entries for new files: backtrace.c,
1242 backtrace.h, stacks.c and stacks.h.
1244 * symbols.c (scm_sym2ovcell): Fixed documentation.
1246 * _scm.h (min, max): Added.
1248 * async.c: Moved `min' macro to _scm.h.
1250 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1251 SCM_BACKTRACE_INDENT.
1253 * eval.c: Added new debug options `maxdepth' and `indent'.
1255 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
1257 * print.h: Added selector SCM_PRINT_STATE.
1259 * print.c: New functions: scm_make_print_state,
1260 scm_free_print_state.
1262 * print.h: Added declarations for scm_make_print_state,
1263 scm_free_print_state.
1265 * debug.c (scm_m_start_stack): New acro.
1267 * debug.h: Small cleanup.
1269 * init.c (scm_boot_guile_1): Moved scm_init_debug below
1272 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

1292 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
1293 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
1294 declare functions with prototypes. (Patch thanks to Marius
1297 More prototype-related changes from Marius Vollmer:
1298 * gdb_interface.h: Wrapped header file in #ifdef/#endif
1299 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
1300 * ports.h (ptobfuns): Added prototypes. This means some casting in
1302 * fports.c: Added casts for initializations, since the functions
1303 are defined to take FILE * as their stream argument, not SCM.
1304 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
1305 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
1306 to `char *str_data' to conform to prototype.
1308 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1310 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
1312 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
1314 * stime.c, stime.h: use SCM_P method.
1316 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1318 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
1319 be given at least two arguments. Insist that lst's last element
1320 be a list, but don't make any requirements of its predecessors.
1322 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1324 * eval.c (scm_nconc2last): Revert last change; there seems to be
1325 other stuff going on here.
1327 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1329 * eval.c (scm_nconc2last): Make sure that each element of lst
1330 (which is a list of argument lists, except for the tail) is a
1331 proper list, i.e., finite and terminated by '().
1333 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1335 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
1338 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
1339 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
1342 * vectors.c (scm_make_vector): Fill vectors with the undefined
1343 value, to help make Guile Scheme code more portable to other
1346 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
1347 * symbols.h, tags.h: Doc fixes.
1349 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
1351 * async.c (scm_take_signal): Doc fixes.
1353 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
1355 * numbers.c (scm_divbigint): When the remainder is zero, we don't
1356 want to subtract it from the modulus; we just want to leave it
1359 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
1361 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
1364 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
1366 * throw.c (scm_catch_apply): Finished implementation of
1369 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
1371 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
1373 (scm_init_filesys): set "i/o-extensions" feature.
1376 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
1378 * Makefile.in (root.o): Correct dependencies.
1380 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
1382 * Makefile.in: Added dependency entry for root.o.
1384 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
1385 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
1387 * init.c (scm_start_stack): Set initial root continuation number
1390 * procs.c: New function: scm_thunk_p.
1392 * procs.h: Added declarations of scm_thunk_p.
1394 * root.c: Renamed `call-with-new-root' -->
1395 `call-with-dynamic-root'.
1396 (cwdr): Removed allocation of new root state. This should be done
1397 separately by use of scm_make_root.
1398 (scm_apply_with_dynamic_root): New function: Does what it
1399 sounds like. Needed when spawning threads.
1401 * root.h: Added member last_debug_frame to root state.
1402 Added #include "libguile/debug.h"
1404 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
1405 arguments. The motivation is that code in root.c needs catch
1406 functionality, and we want to avoid code duplication.
1407 New functions: scm_catch, scm_lazy_catch. These are wrappers for
1408 scm_catch_apply. scm_lazy_catch is intended to introduce catch
1409 handlers that run without popping the stack into the dynwind
1412 * throw.h: Added prototypes for scm_catch_apply and
1415 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1417 * root.h (scm_root, scm_set_root): Decouple thread support details
1418 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
1419 SCM_SET_THREAD_LOCAL_DATA.
1421 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
1422 and tortoise scanning loop.
1424 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
1426 * Makefile.in: Rebuild dependencies.
1428 * libguile.h: #include "libguile/print.h" before "smob.h", since
1429 the latter uses the print_state structure.
1431 * throw.c (scm_ithrow): Use the correct variable when checking to
1432 see if a given element of scm_dynwinds is a valid catch.
1434 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
1435 structure, abort; don't just silently ignore the garbage.
1437 * _scm.h: #include "print.h" here, since it seems to be used just
1439 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
1440 strports.c, unif.h: Don't #include "print.h".
1442 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1444 * feature.h (scm_loc_features): Removed external declaration.
1445 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
1447 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1449 * feature.c (scm_init_feature): Added threads feature (needs to be
1450 initialized here, since features doesn't exist when
1451 scm_init_threads is called).
1453 * libguile.h: Added #include "libguile/../threads/threads.h".
1454 (This is a kludge to get thread support working. This should be
1457 * configure.in, acconfig.h: Added flags for thread support.
1459 * scmsigs.c: Define `signal' to be `pthread_signal' if using
1462 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
1463 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
1466 * _scm.h: Added conditional #include "threads.h"
1468 * __scm.h (SCM_ASYNC_TICK): Added call to macro
1469 SCM_THREADS_SWITCHING_CODE.
1471 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
1472 allocate the basic dynamic root object.
1473 (scm_boot_guile): Added call to scm_init_root.
1475 * root.c, root.h: Added root smob.
1476 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
1477 functions: Implements dynamic roots mostly according to spec in
1478 SCM manual. Main difference is that the second argument is a
1479 throw handler rather than an error "thunk".
1481 * root.h: Added declaration of scm_init_root.
1483 * root.c: Added #include "genio.h", #include "smob.h", #include
1484 "pairs.h", #include "throw.h", #include "dynwind.h", #include
1486 (scm_init_root): Added #include "root.x".
1488 * throw.c: Added #include "stackchk.h"
1489 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
1490 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
1491 can be used in scm_call_with_new_root; Added reenabling of stack
1492 checking when catching a throw.
1494 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
1496 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
1498 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
1499 element is not found, as per R4RS.
1501 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1503 * list.c: Doc fixes throughout.
1505 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1507 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
1508 declare the char * to be const. Avoids a warning in rgx.c.
1510 * ports.h: spelling fix.
1512 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
1515 * load.c (scm_sys_try_load_path): throw an error if file not found
1516 (like it says it in NEWS).
1518 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1520 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
1521 PROPS slot to '(), not #f; it's an empty alist.
1523 * throw.h, throw.c: Use SCM_P instead of #if hair.
1525 Remove special support for uncaught throws; see throw.c for
1527 * throw.c (uncaught_throw): New function.
1528 (scm_ithrow): Call uncaught_throw if we don't find a throw
1529 target; don't mess with scm_bad_throw_vcell.
1530 (scm_bad_throw_vcell): Variable deleted.
1531 (scm_init_throw): Don't initialize it.
1533 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
1536 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1538 * numbers.c (scm_istr2int): If the number is short (as most
1539 numbers are), just call scm_small_istr2int to deal with it.
1540 (scm_small_istr2int): New function, created by un-#ifdefing the
1541 non-bignum version of scm_istr2int and renaming it.
1543 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
1545 * load.c (scm_sys_try_load): don't check whether value returned
1546 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
1547 Change the Scheme name from %try-load to primitive-load.
1549 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
1550 Can avoid passing a message, allowing it to be derived in the
1551 error handler (e.g., if we want to throw to the key both from
1554 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
1556 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
1557 references now have a new appearance which is more compact and
1558 also gives a clue about what the target of the reference is.
1559 By setting parameters in the print state, more fancy printing can
1560 be achieved. This is used by the (not yet commited) backtrace
1563 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
1565 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
1568 * print.c: Added #include "struct.h". Removed function
1571 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
1572 scm_iprin1. Removed prototype for scm_prlist.
1574 * arbiters.c (prinarb),
1575 async.c (print_async),
1576 debug.c (prindebugobj, prinmemoized),
1577 eval.c (prinprom, prinmacro),
1578 filesys.c (scm_fd_print, scm_dir_print),
1580 mallocs.c (prinmalloc),
1581 numbers.c, numbers.h (scm_floprint, scm_bigprint),
1582 smob.h (scm_smobfuns),
1583 srcprop.c (prinsrcprops),
1585 unif.c, unif.h (scm_raprin1, rapr1),
1586 variable.c (prin_var): Changed argument `int writing' to
1587 `scm_print_state *pstate'.
1589 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
1590 that it will be called before scm_init_print.
1592 * print.c (scm_prin1): Print states are now allocated when calling
1593 scm_prin1 and then passed around to all printing functions as an
1594 argument. A cache `print_state_pool' enables reuse of print
1596 (scm_make_print_state): New function.
1597 (scm_iprin1): Adaption to print states.
1598 (scm_iprlist): An initial "hare and tortoise" scan brings down
1599 time complexity to O (depth * N). (Better time complexity will be
1600 achieved when the printing code is completely rewritten.)
1602 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1604 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
1605 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
1606 it gets done whether or not the cache variable has a value.
1608 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
1610 Distinguish #f and ().
1611 * __scm.h: #undef SICP.
1612 * pairs.h (SCM_EOL): Delete this definition, equating it with
1614 * tags.h (SCM_EOL): Give it a new definition here; I think I found
1615 the value it used to have. Doc fixes, too.
1617 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
1619 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
1620 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
1621 Lord's implementation of structs, allowing for tail arrays as
1622 described in the manual. Also fixed some bugs. (Both the interface
1623 and the implementation should be improved.)
1625 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
1627 * print.c, print.h: Closures now print like #<procedure foo (x)>.
1628 People who whish to see the source can do `(print-enable 'source)'.
1629 Removed #ifdef DEBUG_EXTENSIONS.
1631 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1633 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
1634 integer (assuming for now accepting an integer is a good thing).
1636 * error.c, fports.c: replace use of %S in lgh_error args with %s.
1637 %S will be used instead for write'ing arguments.
1639 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
1640 asserts. fix a few other asserts.
1641 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
1642 scm_uniform_vector_ref, scm_array_set_x,
1643 scm_dimensions_to_unform_array): change args in
1644 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
1645 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
1646 scm_substring_fill_x): likewise.
1647 gsubr.c (scm_gsubr_apply): likewise.
1648 eval.c (SCM_APPLY): likewise.
1650 * eval.c (4 places): replace scm_everr with lgh_error or
1653 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
1654 scm_memory_error): new procedures.
1655 scm_everr: deleted. can use scm_wta, dropping first two args.
1656 scm_error: convert NULL subr to SCM_BOOL_F.
1658 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
1661 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
1664 * error.c, error.h: new error keys: scm_arg_type_key,
1665 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
1667 scm_wta: reimplement using lgh_error instead of scm_everr.
1669 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
1671 * gdbint.c: scm_lread now has one more argument.
1673 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
1674 scm_port_\1; Added mutator scm_set_port_filename_x (used when
1675 loading source from non-file ports, which, e. g., happens when
1676 using the Emacs interface).
1678 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
1681 * read.c: Added code for recording of positions of source code
1682 expressions; New functions: recsexpr, scm_lreadrecparen;
1683 _scm_make_srcprops --> scm_make_srcprops
1684 (scm_flush_ws): Removed updating of positions counters. This work
1685 is already done by scm_gen_getc
1687 * read.h: Added prototype for scm_lreadrecparen
1689 * print.c: Added #include "alist.h"
1691 * eval.c: Added #include "hash.h"
1693 * eq.c: Added #include "ramap.h"
1695 * options.c: Documentation fixes.
1697 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
1698 (scm_init_srcprop): Adjusted size of initial source-whash. Name
1699 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
1700 --> scm_make_srcprops
1702 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
1703 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
1704 function calls in the definition of the whash access macros.
1706 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
1708 * init.c (scm_boot_guile): Add level of indirection to
1709 scm_boot_guile_1() to ensure that stack base pointer is properly
1710 initialized. There was no guarantee that variable i was the
1711 highest/lowest variable on stack (i.e. the call frame of
1712 scm_boot_guile was not completely protected from gc).
1714 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
1716 * ports.h (scm_port_table): put back file_name, it will be used to
1717 support debugging. Undo related changes in fports.c, ioext.c,
1720 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1722 * ports.h (scm_port_table): remove file_name member for now, it seems
1724 * fports.c (scm_open_file): don't set file_name in PTAB.
1725 (prinfport): don't use file_name in PTAB.
1726 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
1727 * ports.c (scm_add_to_port_table): don't intialize file_name.
1728 (scm_port_file_name): remove for now.
1729 * gc.c (scm_gc_mark): don't mark PTAB file_name.
1731 * fports.h (scm_mkfile): prototype deleted.
1732 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
1734 * debug.c, unif.c: use scm_out_of_range instead of
1735 wta for range errors (ASSERT still needs work).
1737 * error.c, error.h (scm_out_of_range): new procedure.
1739 * error.c, error.h (scm_out_of_range_key): new key.
1741 * posix.c (scm_sync): #else was missing.
1743 * error.c, error.h: append _key to names scm_num_overflow and
1746 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
1747 of consing an empty list.
1748 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
1749 of macros, saves code and string space.
1750 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
1751 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
1752 lower case. Rename scm_syserror_m to scm_syserror_msg.
1753 error.h: prototypes for new procedures.
1755 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
1757 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
1759 * error.c, error.h: setup scm_num_overflow key.
1761 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
1762 Remove definition of SCM_OVSCM_FLOW.
1764 * fports.c (scm_open_file): use SCM_SYSERROR_M.
1766 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
1767 explicit message and args.
1769 * error.c, error.h, __scm.h: change system_error_sym to
1772 * error.c (system_error_sym): remove leading %% from the Scheme name
1775 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
1777 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1779 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
1780 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
1781 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
1782 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
1783 renamed. (These were introduced by unsupervised name
1786 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1788 * print.c: Added code for detection of circular references during
1789 printing. (init_ref_stack, grow_ref_stack): New functions. Added
1790 a hook for printing of closures (accessible via print options).
1791 This leads to a split of calls to scm_iprin1 into two classes:
1792 elementary print operations (e. g. the code which prints a smob)
1793 still use scm_iprin1 while top level calls (like scm_display) use
1794 scm_prin1. scm_prin1 begins by clearing the data structure used
1795 to record reference information.
1797 * print.h: Added declarations of scm_prin1 and scm_prlist.
1799 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
1801 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
1803 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
1805 * error.c (err_head): scm_iprin1 --> scm_prin1
1807 * debug.c: Adjusted header comment.
1811 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1813 * strerror.c: Doc fix.
1815 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1817 * gdbint.c (gdb_read): Now possible to run during GC.
1818 (unmark_port, remark_port): New functions.
1820 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
1822 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
1823 of allocating a new string object. Also, increase size by
1824 the factor 2 instead of 1.5.
1826 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
1828 * __scm.h (SCM_P): Corrected to run under traditional C.
1830 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
1833 * async.c: Calls to scm_sysintern corrected.
1835 * async.h (scm_async_clock): Redundant declaration removed.
1837 * continuations.c (scm_dynthrow): Redundant declaration removed.
1839 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
1840 Definition typos corrected.
1842 * debug.h: Missing declarations of functions in debug.c added
1845 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
1846 Missing declarations to functions in eval.c added.
1848 * filesys.c: Possibly uninitialized variable rv.
1850 * gc.h (scm_object_addr, scm_unhash_name): Missing
1851 declarations of functions defined in gc.c added.
1853 * genio.c: Possible typos str_data -> wstr_data. ???
1855 * genio.c: Possibly unintended shadowing of local variable
1856 `int c' (gotos out of scope of inner `c'). ???
1858 * init.c: Uninitialized `SCM last' may be used.
1860 * ioext.h: (scm_sys_isatty_p): Typo.
1862 * list.h (scm_list_head): Missing prototype for function in
1865 * numbers.c (scm_two_doubles): Changed from extern to static
1866 (is used only within numbers.c).
1868 * numbers.h: Repeated declarations removed.
1870 * ports.h (scm_close_all_ports_except): Declaration for the
1871 function defined in ports.c added.
1873 * posix.h: Missing declarations added.
1875 * procs.h (scm_make_subr_opt): Missing declaration added.
1877 * socket.h (scm_sys_gethost): Missing declaration added.
1879 * socket.h: Redundant declarations removed (they are in fdsocket.h).
1881 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
1882 Missing declarations added.
1884 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
1886 * struct.c: Uninitialized variable `SCM answer' may be used.
1888 * unif.c (l2ra): Declaration prototype.
1890 * unif.c (scm_array_equal_p): Dummy definition removed (it is
1891 defined in ramap.c).
1893 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
1894 Redundant declarations removed (they are in ramap.h).
1896 * variable.h (scm_make_udvariable,
1897 scm_make_undefined_variable): Declaration corrected to
1898 correspond variable.c.
1900 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
1901 Missing declarations added.
1903 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
1905 * Makefile.in (distclean): Don't forget to delete fd.h.
1907 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1909 * fd.h.in, tags.h: Trivial cleanups.
1911 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
1912 marksweep.h just declared functions from gc.c.
1913 * gc.h, libguile.h: Don't #include "marksweep.h".
1914 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
1915 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
1916 dependencies updated.
1918 * libguile.h: Don't #include "files.h"; it's been deleted.
1920 * files.c (scm_sys_delete_file): Moved to filesys.c.
1921 File is now empty; deleted.
1923 * filesys.c: scm_sys_delete_file is now here. Remove
1924 #if's; they seem to rely on remnants of an old portability
1925 regimen. If the problems come up again, solve them properly,
1926 using autoconf. Specifically: Don't test M_SYSV, and #define
1927 remove to be unlink if it's #defined; don't use remove just
1928 because HAVE_STDC_HEADERS is #defined.
1929 * filesys.h: Add declarations for scm_sys_delete_file.
1930 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
1931 files.o, files.h, files.c, and files.x.
1932 * init.c: Don't #include "files.h", and don't call scm_init_files.
1934 Use SCM_P instead of PROTO; the latter intrudes on the user's
1936 * params.h: Deleted; definition of SCM_P moved to...
1937 * __scm.h: ... here, where it replaces PROTO macro.
1938 * libguile.h, smob.h: Don't #include "params.h".
1939 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
1940 smob.h: Fix prototypes accordingly.
1941 * Makefile.in: Update dependencies.
1942 (inner_h_files): Remove params.h.
1944 * gc.c: #include "gc.h"; every module should include its header,
1945 to let the compiler cross-check the declarations against the
1948 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
1949 simpos.h: #include "libguile/__scm.h".
1951 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
1953 * init.c: Don't forget to #include smob.h and init.h.
1954 * Makefile.in: Dependencies updated.
1956 * smob.h: Use PROTO instead of #if __STDC__.
1958 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
1960 * __scm.h: Doc fixes.
1962 * __scm.h, libguile.h: Use "quotes" in the #includes, not
1963 <angles>; this allows `make depends' to work properly.
1965 * libguile.h: #include smob.h and pairs.h before the others; they
1966 define typedefs used by other headers.
1968 C files should #include only the header files they need, not
1969 libguile.h (which #includes all the header files); the pointless
1970 recompilation was wasting my time.
1971 * Makefile.in (all .o dependency lists): Regenerated.
1972 * libguile.h: Don't try to get a definition for size_t here...
1973 * __scm.h: Do it here.
1974 * _scm.h: Since this is the internal libguile header, put things
1975 here that all (or a majority) of the libguile files will want.
1976 Don't #include <libguile.h> here; that generates dependencies on

2078 * stackchk.h: #include "libguile/debug.h",
2080 * print.h, read.h: #include "options.h", since everyone who uses
2081 either of these files will need that.
2083 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2084 anyone who uses this file will need them to define the smob
2085 printing functions. Also, get markers.h, since people will need
2086 to #define the mark functions.
2088 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2089 * ports.h: ... to here.
2091 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2092 don't rely on archaic C default type rules.
2094 * fports.h: #include "libguile/ports.h", since you need that in
2095 order to parse this.
2097 * genio.h: #include "libguile/print.h", because you need that to
2098 parse this; don't bother #including "ports.h", since print.h gets
2101 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2103 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2104 this; it's now a reference to an element of *scm_root.
2106 * debug.h: Don't #include "options.h"; the compiler won't be able
2107 to find that once the headers are installed; instead, #include
2108 "libguile/options.h".
2109 * gc.h: Same, with marksweep.h.
2110 * mbstrings.h: Same, with symbols.h.
2111 * scmhob.h: Same, with _scm.h.
2112 * smob.h: Same, with params.h.
2114 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2115 C files; there's no need for this, and it forces recompilations
2118 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2120 * error.c (scm_error): declare scm_error_callback.
2122 * error.h: prototype for scm_error_callback.
2124 * __scm.h: define lgh_error.
2125 (SCM_SYSERROR): redefine using lgh_error.
2127 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2129 * error.c (scm_error): new procedure.
2131 * error.h: prototype for scm_error.
2133 * Makefile.in (install): install scmconfig.h from the current
2134 directory, not $(srcdir).
2136 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2138 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2139 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2140 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
2141 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
2142 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,

2145 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2146 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2147 vports.h, weaks.h: #include "libguile/__scm.h", not
2148 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2149 dependencies are within libguile properly.
2151 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2153 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2154 when scmconfig.h doesn't exist.
2156 * load.c (scm_sys_try_load): Correct spelling.
2158 * feature.c (scm_loc_features): Make this static.
2160 * Makefile.in (libpath.h): Omit trailing slash from path. We
2161 shouldn't require it of users, so why put it here?
2163 Move code to initialize and search %load-path from ice-9 to C
2164 code, so we can use the load-path to find the ice-9 boot code;
2165 this makes it easier to run Guile without installing it. See
2166 corresponding changes in guile/Makefile.in.
2167 * feature.c: Move stuff concerned with the load path to load.c.
2168 (scm_compiled_library_path): Deleted.
2169 Don't #include libpath.h here.
2170 * feature.h: Don't mention scm_compiled_library_path.
2171 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2172 <sys/stat.h>, and <unistd.h> (if present).
2173 (R_OK): #define if the system hasn't deigned to.
2174 (scm_loc_load_path): New variable.
2175 (scm_init_load_path, scm_sys_search_load_path,
2176 scm_sys_try_load_path): New functions.
2177 (scm_init_load): Initialize scm_loc_load_path to point to the
2178 value cell of the Scheme %load-path variable.
2179 * load.h: Add declarations for scm_sys_search_load_path,
2180 scm_sys_try_load_path.
2181 * init.c: Call scm_init_load_path.
2182 * Makefile.in (feature.o, load.o): Dependencies updated.
2184 * load.c, load.h: Rewrite using PROTO macro.
2186 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2188 * gc.c (scm_cellp): New function: C predicate to determine if an
2189 SCM value can be regarded as a pointer to a cell on the heap.
2191 * gc.h: Added declaration of scm_cellp.
2193 * gdb_interface.h: New file: The GDB interface header from the GDB
2196 * gdbint.c: New file: GDB interface.
2198 * gdbint.h: New file: GDB interface.
2200 * libguile.h: Added #include <libguile/gdbint.h>.
2202 * init.c (scm_boot_guile): Added scm_init_gdbint.
2204 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2205 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2206 found if object files and source are kept separate).
2208 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2210 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2212 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2214 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2215 TK_SRC_DIR; they're not relevant any more.
2217 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2218 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2220 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2222 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2223 search path, so we can find the <libguile/MUMBLE.h> headers.
2225 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2227 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2228 implicit in the .c.o rule.
2229 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2232 Put the library path in a header file, instead of passing it on
2233 the command line in every compilation.
2234 * Makefile.in (libpath.h): New target.
2235 (feature.o): Depend on libpath.h.
2236 (clean): Delete libpath.h.
2237 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2238 * feature.c: ... #include "libpath.h" here.
2239 * .cvsignore: Ignore libpath.h.
2241 Don't install the unwashed masses of Guile header files in the
2242 main #include path; put most of them in a subdirectory called
2243 'libguile'. This avoids naming conflicts between Guile header
2244 files and system header files (of which there were a few).
2245 * Makefile.in (pkgincludedir): Deleted.
2246 (innerincludedir): New variable; this and $(includedir) are enough.
2247 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
2248 (installed_h_files): Divide this up. Now this variable lists
2249 those header files which should go into $(includedir) (i.e. appear
2250 directly in the #include path), and ...
2251 (inner_h_files): ... this new variable says which files appear in
2252 a subdirectory, and are referred to as <libguile/mumble.h>.
2253 (h_files): List them both.
2254 (install): Create innerincludedir, not pkgincludedir. Put
2255 the installed_h_files and inner_h_files in their proper places.
2256 (uninstall): Corresponding changes.
2257 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2258 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2259 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
2260 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
2261 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
2262 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2263 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2264 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2265 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2266 vports.h, weaks.h: Find __scm.h in its new location.
2267 * __scm.h: Find scmconfig.h and tags.h in their new locations
2268 (they're both "inner" files).
2270 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
2272 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
2274 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2276 * posix.c: Doc fixes.
2278 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
2280 * socket.c: Don't include a prototype for inet_aton; just use a
2281 K&R style declaration, to avoid warnings but minimize the chance
2282 of conflicts with the system.
2284 On NextStep, <utime.h> doesn't define struct utime, unless we
2285 #define _POSIX_SOURCE before #including it.
2286 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
2287 * acconfig.h: New comment text for above CPP symbol.
2288 * configure.in: Call it.
2289 * posix.c: #define _POSIX_SOURCE if it seems necessary.
2291 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
2293 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
2294 testing for __EMX__.
2296 * posix.c: #include <libc.h>, if it exists.
2298 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
2299 don't even know if the latter exists.
2301 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
2302 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
2303 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
2305 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
2307 (scm_init_posix): Use them when initializing the Scheme constants
2310 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2312 * Makefile.in (libdir, includedir, bindir): Use the
2313 autoconf-supplied values, instead of deriving them ourselves.
2314 (pkgincludedir, datadir, pkgdatadir): New variables.
2315 (install, uninstall): Put the header files in a special
2316 subdirectory, not in the main search path.
2318 * Makefile.in (ALL_CFLAGS): Provide the proper value for
2319 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
2321 * Makefile.in (IMPLPATH): Deleted; never used.
2323 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
2324 on the Tcl/Tk source any more.
2325 (INCLUDE_CFLAGS): Remove references to the above.
2327 * Makefile.in (version.o): Corrected dependencies.
2329 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
2331 * libguile.h: #include "version.h"
2333 * init.c (scm_boot_guile): Call scm_init_version.
2334 * gscm.c (gscm_run_scm): Call scm_init_version.
2336 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
2337 GUILE_VERSION): AC_DEFINE these.
2338 (acconfig.h): #undef the above symbols.
2340 * Makefile.in (libobjs): Add version.o.
2341 (installed_h_files): Add version.h.
2342 (c_files): Add version.c.
2343 (gen_c_files): Add version.x.
2344 (version.o): New rule.
2345 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
2346 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

2355 weaks.o): Add version.h to dependency lists.
2356 (markers.o): Remove duplicate rule.
2358 * version.h: New file.
2360 * version.c: New file.
2362 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2364 * symbols.c (scm_strhash): scm_downcase is now a function, not an
2365 array; use it appropriately. Since GCC is quite happy to
2366 subscript functions, it never warned us about this; we should use
2367 -Wpointer-arith in the future. I guess we never tested
2370 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2372 * socket.c: Doc and copyright fixes.
2374 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2376 * debug.c: Fixed and improved gdb support.

2380 * socket.c: Added declaration of inet_aton to avoid compiler
2381 warning. (Hope this solution is correct.)
2383 * stime.c: Added declaration of ftime. (This is missing in
2386 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
2388 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2390 * Makefile.in (c_files): add strerror.c.
2392 * strerror.c: new file from Emacs' sysdep.c.
2393 maybe configure should also check for sys_errlist.
2395 * configure.in (AC_REPLACE_FUNCS): add strerror.
2397 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2399 * debug.c (scm_init_debug): Added initialization for
2400 scm_evaluator_traps.
2402 * debug.h, debug.c: Various name changes.
2403 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
2404 "debug-options-interface". See commentary in options.c.
2406 * options.h, options.c: Options now have documentation strings.
2407 Also added a long explanatory commentary.
2409 * eval.c, print.h, print.c, read.h, read.c: Modifications to
2412 * gscm.c, init.c, root.c, throw.c: Bug fixes:
2413 last_debug_info_frame is now updated in all cases.
2415 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
2418 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2420 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
2421 Added option STACK_CHECKING.
2423 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
2425 * Makefile.in: Added {debug,options,srcprop}.{h,c}
2427 * __scm.h: Removed symbols for debugging support.
2429 * acconfig.h: Added symbols for debugging support.
2431 * configure.in: Added user option for debugging support.
2432 --enable-debug will include the debugging code into libguile.a.
2434 * continuations.c (scm_make_cont): Enlarged the #if 0 around
2435 scm_relocate_chunk_to_heap.
2437 * debug.c: New file: low-level debugging support. It also
2438 includes support for debugging with gdb. (The extensions to gdb
2439 are written by Per Bothner at Cygnus.)
2441 * debug.h: New file: low-level debugging support.
2443 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
2444 argument pairs. Extensive modifications to the debugging
2445 evaluator. Added "SECTION:" commentaries to clarify what happens
2446 when, during double compilation. Renamed EVALIMP --> EVALIM.
2447 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
2448 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
2449 the beginning of the file. New procedure: scm_unmemocopy.
2450 Added some global state variables needed by the debugging
2451 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
2452 check_entry, check_apply, check_exit, debug_options and
2453 evaluator_traps. New acro: undefine.
2455 * eval.h: Renamed EVAL --> XEVAL.
2457 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
2458 --> scm_make_weak_key_hash_table.
2460 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
2461 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
2463 * libguile.h: Conditionally include debug.h
2465 * objprop.c (scm_object_properties, scm_set_object_properties_x):
2466 scm_object_properties shouldn't return handle. `handle' now gets
2467 initialized in scm_set_object_properties_x. scm_object_properties
2468 doesn't any longer create an entry in scm_object_whash.
2470 * options.c: New file: handling of run time options.
2472 * options.h: New file: handling of run time options.
2474 * posix.c (scm_getpgrp): Cast pointer to getpgrp.

2495 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2497 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
2499 * libguile.h: #include "objprop.h"; I guess this was forgotten.
2501 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
2502 and should be called by the final client.
2504 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
2506 * gc.h: Use the PROTO macro when declaring functions.
2507 * gc.c: Use the PROTO macro when declaring static functions.
2508 Remove the CPP hair around function definitions.
2510 * gc.c (scm_init_storage): Initialize scm_asyncs.
2512 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
2513 preprocessor symbol; "__scm.h" is where it might get #defined.
2514 * __scm.h: Similar: #include <scmconfig.h> before testing
2517 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
2519 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
2521 * init.c (scm_boot_guile): Add init_func argument; call
2522 (*init_func) instead of calling scm_appinit; it's ucky to
2523 hard-code names for the user's procedures.
2524 * init.h (scm_boot_guile): Adjust declaration.
2526 * __scm.h (PROTO): New macro, for declaring functions with
2529 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
2530 eliminate all the __STDC__ conditionals.
2531 (scm_boot_guile): Add declaration.
2532 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
2533 Remove __STDC__ conditionals around function definitions; the
2534 declarations in init.h will provide the same information, more
2537 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
2538 complain about it in the error message; the error message is
2539 adequate without that note, and there's nothing the user can do
2542 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
2544 * Makefile.in (ancillary): Drop def.sed.
2546 * posix.c (scm_init_posix): Use numeric values, rather than
2547 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
2548 F_OK. The symbols aren't available on some systems, and I'm
2549 pretty sure their values are fixed by common widespread practice.
2550 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
2552 More functions unavailable on some systems.
2553 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
2554 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
2556 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2557 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
2558 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
2559 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
2560 stub that signals an error as the #else.
2562 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
2564 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
2566 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
2568 * unif.c: include ramap.h.
2570 * read.c (endif): case_insensative_p renamed case_insensitive_p.

2574 * ports.c: include sys/ioctl.h.
2576 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
2578 * configure.in: check for sys/ioctl.h.
2580 * ports.c: include <malloc.h> not "malloc.h".
2582 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2584 * fports.c: remove ttyname and tmpnam declarations.
2586 * posix.c: fewer ttyname declarations.
2588 * fports.c: include <string.h> not "string.h".

2592 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2594 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
2595 genio.c, simpos.c, vports.c: include string.h.
2597 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
2599 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
2601 (scm_addr_buffer_size): change type from scm_sizet to int.
2602 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
2603 from scm_sizet to int.
2605 * error.c: include unistd.h.
2607 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
2610 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
2612 * __scm.hd, def.sed: deleted.
2614 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
2616 Changes for NeXT, suggested by Robert Brown.
2617 * configure.in: Call AC_TYPE_MODE_T.
2618 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
2619 NeXT. Put header file list in alphabetical order.
2620 * configure, scmconfig.h.in: Regenerated.
2621 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
2623 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
2626 * acconfig.h: New file, providing documentation for the CPP
2627 symbols defined in configure.in
2628 * acconfig-1.5.h: Removed; superceded by the above.
2630 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
2632 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
2634 * fports.c (scm_open_file): don't return #f, throw error.
2636 * ioext.c (fileno): renamed from %fileno.
2637 (soft-fileno): deleted.
2639 * ports.c (scm_port_revealed): don't need to check for -1 from
2641 (scm_set_port_revealed_x): return unspecified, not #f.
2643 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
2645 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
2647 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
2649 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
2651 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2653 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
2654 This is necessary on Ultrix, and doesn't hurt portability.
2656 * Makefile.in (dist-dir): New target, implementing a new dist system.
2657 (installed_h_files): Put in alphabetical order.
2658 Remove duplicate entries for markers.h and unif.h.
2659 (c_files): Remove duplicate entries for markers.c.
2660 (ancillary): Renamed from anillery; all uses changed. Remove
2661 PLUGIN; it's a directory, and needs special treatment in dist-dir.
2662 Remove all the ../doc/* files; doc/Makefile.in handles that.
2664 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
2666 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
2667 every if must have an else, or else the whole command has a
2668 non-zero exit code whenever the if's condition is false.
2670 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
2672 * posix.c: include string.h.
2674 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2676 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
2679 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
2680 Remove leading % from scheme names.
2681 Do not return error values, call SCM_SYSERROR or similar.
2683 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
2685 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
2687 * struct.c (scm_init_struct): new file.
2689 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
2691 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
2692 (scm_list_head): added list-head for rapidly chopping argument
2693 lists off of longer lists (and similar).

2698 handle for obj, not the handle itself.
2700 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
2702 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
2703 weak hash tables last of all marking to avoid an obscure gc bug.
2704 WARNING: circular lists stored in a weak hash table will hose us.
2706 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
2708 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
2709 new functions similar to scm_substring_move_left_x and
2710 scm_substring_move_right_x.
2712 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
2714 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
2717 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
2719 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
2721 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
2723 * strports.c (scm_strprint_obj): convenience function. C for
2724 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
2726 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
2727 removed to a separate library
2729 * init.c (scm_boot_guile): copied from guile-tcl.c.
2730 Initialization specific to tcl interpreters removed.
2732 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
2734 * ports.c (scm_ports_prehistory): size malloced here doesn't
2735 matter so long as it is non-0 (got rid of "* 4").
2737 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
2739 * gscm.h: gscm_mkarray eliminated (presumably was not being used
2740 since its definition was bogus).
2742 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
2744 * mallocs.[ch]: back again (for rx at least).
2746 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
2748 * ports.c: removed functions relating to the mapping between ports
2749 and descriptors. (That stuff is unix-specific and should be collected
2750 in a separate library).
2752 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
2753 (Tom Mckay@avanticorp.com)
2755 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
2757 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
2758 handled correctly (SCM_FREEP was applied to them) -- test for
2759 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
2760 being overwritten with #f. (brown@grettir.bibliotech.com)
2762 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>

2792 NOTE: don't use a alist here.
2793 (scm_set_procedure_properties_x): fix type checking throughout this file.
2795 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
2797 * ports.c (scm_remove_from_port_table): adjust scm_mallocated

2803 * vports.c (scm_make_soft_port): allocate a port table entry
2804 (possibly triggering gc) before setting the tag of the corresponding
2807 * pairs.c (scm_delq_x): never throw an error.
2809 * vectors.c (scm_make_vector): made the default vector fill argument
2810 into '() (much more useful than the previous value, "#unspecified")
2812 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
2814 * ports.c (scm_add_to_port_table): Added fields
2815 to port table entries: file_name, line_num, col.
2816 Update these in open_file, gen_getc and gen_ungetc.
2817 Added procedures to access those fields.
2819 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
2821 * procs.c (scm_make_subr_opt): new entry point for making
2824 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
2826 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
2828 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
2830 * numbers.c (scm_exact_p): This function no longer
2831 implements "integer?".
2833 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
2835 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
2836 (scm_gc_stats): return an assoc of useful data. Replaces "room"
2837 and the stats reporting formerlly built into repl.
2839 * repl.[ch]: removed.
2840 GC statistics keeping moved to gc.c.
2841 Other statistics keeping can be done from Scheme.
2842 REPLS are now written in Scheme.

2853 * feature.c (scm_compiled_library_path): moved here from repl.c.
2854 This file is for stuff relating specifically to Scheme libraries
2857 * eval.c (scm_m_define): don't give warning about redefinition, don't
2860 NOTE: this should throw a resumable exception with parameters --
2861 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
2863 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.

2881 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
2884 * strports.c: don't reveal the port's string to the caller
2885 because it changes size.
2887 (stputc stwrite): check/change the strings length with interrupts
2890 * objprop.c (scm_set_object_property_x &c): use the generic
2891 hashing functions and be threadsafe.

2894 (per suggestion jaffer@gnu.ai.mit.edu).
2896 * mbstrings.c (scm_multi_byte_string): guard against argument list
2899 * strings.c (scm_make_string): loop cleanup
2901 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer

2953 set the multi_byte flag correctly in symbols. This is wrong.
2954 intern_obbary_soft and msymbolize should take an extra parameter.
2955 Also, weird multibyte symbols don't print correctly.
2956 The weird symbol syntax is also a bit bogus (emacs doesn't quite
