1 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3 * symbols.c (msymbolize): Bugfix: Must initialize property list to
6 * procs.c: Introduce the existent C function scm_thunk_p at the
9 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
11 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
12 used from C to easily lookup the value of a symbol in the current
15 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
17 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
18 scm_init_unif in this file. This will also fix a previous problem
21 * configure.in: Added AM_MAINTAINER_MODE
23 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
25 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
28 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
30 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
31 source files that are not always included in libguile but should
32 have their dependencies calculated by automake. This variable is
33 recognized by automake, no further magic is needed.
34 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
35 to deal exclusively with *.lo files, as it seems. The *.o files
36 are built automatically when the corresponding *.lo file gets
39 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
41 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
44 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
46 * unif.c (scm_array_set_x): minor change to argument error checking.
48 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
50 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
51 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
52 They should only be included in the library at configure.in's
54 (libguile_la_LDADD): Include the appropriate .lo files here.
55 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
56 so we know when to build them (and their .lo bretheren).
57 * configure.in (LIBLOBJS): New substituted variable. We let
58 configure decide which .o files to include in LIBOBJS, and then
59 put the corresponding list of .lo files in LIBLOBJS. The latter
60 is what we pass to libtool.
61 * Makefile.in, configure: regenerated.
63 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
65 * symbols.c (scm_sysintern0): New function. Contains the core of
66 old scm_sysintern but doesn't take a second value argument.
67 (scm_sysintern): Now uses scm_sysintern0.
68 (scm_sysintern_no_module_lookup): Renamed to
69 scm_sysintern0_no_module_lookup and doesn't take a second value
72 * symbols.h (scm_sysintern0: Added declaration.
74 * options.c (scm_init_opts): Use scm_sysintern0 instead of
75 scm_sysintern when interning option keys. Otherwise we risk
76 destroying the values of already interned variables.
78 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
79 scheme-level boolean (use SCM_NFALSEP).
81 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
83 (scm_backtrace): New function. (C version of old function from
84 boot-9.scm) Motivation: Make it possible to display backtraces
85 without depending on boot-9.scm. (I'm uncertain if this
86 motivation is good enough...)
88 * root.h (scm_root_state): Add member the_last_stack_var.
89 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
91 * root.c (mark_root): Mark scm_the_last_stack_var.
93 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
96 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
98 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
99 1. mark_lazy_catch didn't mark the smob.
100 2. Both functions above have standard variants:
101 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
102 free_lazy_catch --> scm_free0.
104 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
106 * throw.c (scm_internal_lazy_catch): New function.
107 (scm_lazy_catch): Rewritten to use it.
108 (scm_ithrow): Handle the new lazy catch representation.
109 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
110 that doesn't have a jmpbuf is a lazy catch clause.
111 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
112 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
113 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
115 (scm_init_throw): Register the new lazy-catch smob type.
116 * throw.h (scm_internal_lazy_catch): decl for new function.
118 * throw.c (scm_internal_catch): Doc fixes.
120 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
121 configure.in. Including this might cause problems if applications
122 that link against libguile include their own copies of alloca, but
123 if they're using autoconf, they should be adding libguile to LIBS
124 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
125 the copy in libguile, and things will be okay. (I think.)
127 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
129 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
131 strop.h: move prototypes too.
133 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
135 * posix.c (scm_init_posix): don't intern EINTR since it's now done
138 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
139 etc. I deleted them from filesys.c long ago, but didn't
140 notice they were here too (although ineffective since
141 sys/stat.h wasn't included).
143 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
145 * eval.c: Don't define alloca in GCC case. gcc will automatically
146 use __builtin_alloca if appropriate.
148 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
150 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
151 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
152 that values of automatic variables are preserved. See comments
153 for safe_setjmp for details.
155 Change from Thomas Morgan:
156 * variable.c: Include eq.h.
157 (var_equal): New function.
158 (variable_smob): Use var_equal as the discriminator for variables.
160 * throw.c (s_throw): Remove extraneous declaration.
162 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
163 * eval.c: Add necessary CPP cruft to support that.
164 * configure, Makefile.in, scmconfig.h.in: regenerated.
166 Change from Thomas Morgan:
167 * procprop.c (scm_procedure_properties): Convert the Scheme
168 boolean returned by scm_procedure_p into a C boolean before using
169 it as a condition for SCM_ASSERT.
170 (scm_procedure_property): Likewise.
172 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
173 indications of Unixness.
176 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
178 * * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
180 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
182 * read.c (scm_lreadr): use scm_misc_error to improve one of the
183 "unknown # object" error messages.
185 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
186 (scm_i_index) and declare it static. Add a 'direction' argument
187 to indicate what way the search should go.
188 (scm_i_index): throw out-of-range error instead of wrong-type-arg
190 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
191 strop.h: remove scm_i_index, scm_i_rindex prototypes.
193 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
195 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
197 * * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
198 to avoid clash with various scsh forks.
200 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
202 The following two changes (ramap.c, throw.c) are motivated by the
203 apparent unportability of forward declarations of static arrays of
204 the form `static foo bar[];'.
206 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
207 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
209 * throw.c (scm_throw): Moved above scm_ithrow.
211 * options.h: Removed the extern declarations of scm_yes_sym and
212 scm_no_sym since these are static.
214 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
216 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
218 * Makefile.am: remove AWK=@AWK@.
219 Add a rule for generating errnos.list.
220 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
222 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
223 don't extract errnos, just set a variable (avoids the
224 need to recompile error.c just because configure is run.)
226 * unif.h: update prototypes.
227 * unif.c (scm_uniform_array_read,write): change the offset and
228 length arguments to start and end, for consistency.
230 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
232 * ioext.h: update prototypes.
233 * * ioext.c (scm_read_delimited_x): replaces scm_read_line and
234 scm_read_line_x, it's a more general procedure using an
235 interface from scsh. read-line and read-line! are now defined
237 * Note that the new read-line trims the terminator
238 by default, previously it was appended to the returned string. An
239 optional argument specifies how to process the terminator (scsh
240 compatible). For the old behaviour: (read-line port 'concat).
241 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
242 returns a pair, but is converted to multiple values if the scsh
245 socket.h: update prototypes.
246 * socket.c (scm_recvfrom): for consistency with other procedures,
247 take start and end as separate optional arguments.
248 * (scm_recv, scm_recvfrom): don't allow the second argument
249 to be a size, only a buffer. Change the scheme names to
250 recv! and recvfrom!. Don't return the buffer.
252 * ioext.h, posix.h: move prototypes too.
253 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
254 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
255 "read.h" and "unif.h".
256 * ioext.c: include "chars.h"
258 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
260 * dynl.c: The dynamic linking and module registration functions
261 are now defined even when dynamic linking is not available for the
262 host system. Some of their functionality can be done without
263 dynamic linking; when it's really needed, they throw errors.
265 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
267 * configure.in: Only define DYNAMIC_LINKING when one of the system
268 dependent functions is detected.
269 * dynl.c (scm_dynamic_func): New function to get the address of a
270 function in a dynamic object.
271 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
272 produced by scm_dynamic_func as the thing to call.
274 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
276 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
277 (scm_register_module_xxx, scm_registered_modules,
278 scm_clear_registered_modules): New functions.
280 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
282 * symbols.c (scm_sysintern): Renamed to
283 scm_sysintern_no_module_lookup.
284 (scm_sysintern): New function to take the place of the old
285 scm_sysintern. It uses the current toplevel lookup closure to give
286 the symbol its value. This is a temporary hack to put packages
287 like gtcltk into their own module.
288 (scm_can_use_top_level_lookup_closure_var): New variable to tell
289 us whether `scm_top_level_lookup_closure_var' has been initialized
291 * eval.c (scm_init_eval): Set it.
293 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
295 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
296 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
298 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
300 * (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
301 scm_sys_dup): deleted: FD capability will be added to other
303 * Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
304 scm_fd_free, fd_smob, scm_intern_fd.
305 * (scm_open): renamed from scm_sys_open. Return a port instead of
306 an FD object. Make the mode argument optional.
307 * (scm_sys_create): deleted, it's just a special case of open.
308 (scm_init_filesys): move interning of constants O_CREAT etc.,
309 here (were previously using SCM_CONST_LONG macro).
310 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
312 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
313 include "fports.h" and <stdio.h>
314 (scm_stat, scm_select): don't support FD objects.
316 * error.h: adjust scm_syserror_msg prototype.
317 * error.c (scm_syserror_msg): take an extra argument for errno.
318 Using the global value didn't always work, since it could be
319 reset by procedure calls in the message or args arguments.
321 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
322 I don't understand why the check was there (and what about the
325 * strop.c (scm_string_copy): allow shared substrings to be copied.
327 * unif.h: corresponding change to prototypes.
328 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
329 recognize two new optional arguments: offset and length. Allow
330 the port argument to be an integer (file descriptor, for scsh).
331 Include <unistd.h> for "read" prototype.
333 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
335 * socket.c: don't include filesys.h.
337 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
339 * Makefile.am: add AWK=@AWK@ (?)
341 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
343 Add a rule to generate errnos.c from errnos.
344 * error.c (scm_init_error): include errnos.c.
345 * errnos_cnvt.awk: new file, converts the list of errno codes to
347 * errnos_get.c: new file.
348 * errnos.default: new file, contains errnos to try if they can't
349 be extracted from errno.h.
350 * configure.in: if using GCC, try and extract errno codes from
354 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
356 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
357 * Makefile.am: Made libguile into a libtool library.
358 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
359 Set libtool_libs to indicate that libguile is a libtool library.
360 See guile/ChangeLog for details.
361 * .cvsignore: ignore "*.lo", the libtool library objects.
363 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
365 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
366 use htons in getservbyport argument.
368 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
370 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
371 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
374 * objprop.c (scm_object_property): No need to take the CDR of the
375 value returned by scm_object_properties, since Aug 20 change.
377 * configure.in: When checking for struct linger, #include
378 <sys/types.h> as well as <sys/socket.h>. I've never known
379 <sys/types.h> to cause any portability problems, and Solaris's
380 <sys/socket.h> needs it.
381 * configure: Rebuilt.
383 I think the Sun compiler has chosen a perverse way to interpret
384 ANSI declarations combined with K&R definitions. We'll
385 appease it a little bit. But when it invades France, we fight.
386 * print.c (scm_iprlist): Change 'tlr' argument to an int.
387 * print.h (scm_iprlist): Here too.
388 * numbers.c (scm_divbigdig): Change definition to match
389 declaration in numbers.h.
390 * unif.c (scm_makflo): Change definition to match declaration in
393 * init.c (scm_boot_guile): Don't return the value of
394 scm_boot_guile_1. This function doesn't return a value;
395 scm_boot_guile_1 doesn't return a value (or return at all).
397 * eval.c (unmemocopy): Add a semicolon to appease the Sun
400 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
401 compile. I have a feeling this function is a bad idea anyway ---
402 one should always test for features, not systems.
404 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
405 semicolons. Only pure luck kept this from being noticed earlier.
407 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
409 * socket.c (scm_recvfrom): Added missing semicolon.
411 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
413 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
414 the buffer and start and end positions for scsh networking
417 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
419 * configure.in: Revert previous change to this file; the problem
420 is due to transient automake weirdness.
421 * configure: Rebuilt.
423 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
424 PLUGIN/guile.libs. configure generates the latter from the former.
425 * Makefile.in: Rebuilt.
427 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
428 need this if we install scripts, like guile-snarf.
429 * configure: Rebuilt.
431 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
433 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
435 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
437 * socket.c (scm_addr_vector): fix faulty scm_listify.
439 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
441 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
442 style block comment is no longer considered an error.
444 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
446 * PLUGIN/guile.libs.in: New file.
447 * PLUGIN/guile.libs: Removed from repository.
448 * configure.in: Create PLUGIN/guile.libs from
449 PLUGIN/guile.libs.in. This is for including additonal libraries
450 needed for dynamic linking.
451 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
452 instead of PLUGIN/guile.libs.
454 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
456 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
458 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
459 occurrences of the given element from the list, not just the
460 first. This is how the Emacs Lisp functions behave, how the
461 analogous Common Lisp functions behave, and (I believe) how the
462 older Maclisp functions worked. I realize that this change may
463 break code, but it seemed better to break it before the Guile
466 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
467 Their prototypes were already present in gc.h, but they weren't
469 (scm_init_storage): Initialize scm_protects.
470 * root.c (scm_protects): New element of scm_sys_protects.
472 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
474 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
476 * libguile.h: Added #include "libguile/net_db.h".
478 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
479 30 change. That file is only meant for communication between the
480 configuration process and load.c. If code linked against libguile
481 wants to get at the paths mentioned in libpath.h, it can call
482 functions declared in load.h.
484 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
486 * libguile.h: Removed #include "libguile/fdsocket.h"
488 * net_db.c: Added #include <sys/socket.h>.
490 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
492 * filesys.c (scm_input_waiting_p): use select in preference to
493 FIONREAD, since the latter doesn't detect EOF.
494 Throw error if neither select nor FIONREAD available.
496 * socket.c (scm_connect): take a port, not a fd object.
497 (scm_fill_sockaddr): throw an error if fam is not recognised.
498 (scm_bind): use scm_fill_sockaddr.
499 (scm_listen): take a port, not a fd object.
500 (scm_accept): take and return a port. return #f in the car if
502 (scm_sock_fd_to_port): new procedure.
503 (scm_socket): use scm_sock_fd_to_port.
504 (scm_addr_vector): throw error if unrecognised address type.
505 take an extra argument with the calling procedure name.
506 (scm_getsockname): take a port. return #f if address can't be got.
507 (scm_getpeername): take a port. return #f if address can't be got.
508 (scm_recvfrom): take a port. return #f for address component if can't
510 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
511 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
513 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
515 * throw.c (scm_internal_catch): Make body funcs and handler funcs
516 use separate data pointers, to allow them to be designed
517 independently and reused.
518 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
519 Renamed from catch_body, catch_handler, and uncaught_throw; made
521 (struct scm_catch_body_data): Renamed from catch_body_data; moved
523 (scm_catch): Use the above.
524 (scm_throw): Don't bother printing a message for an uncaught
525 throw; we establish a default handler in init.
526 * throw.h (scm_internal_catch): Prototype updated.
527 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
529 (struct scm_body_thunk_data): New structure, used as data
530 argument to scm_body_thunk.
531 * init.c (struct main_func_closure): New structure, packaging up
532 the data to pass to the user's main function.
533 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
534 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
535 scm_internal_catch to establish a catch-all handler, using
536 scm_handle_by_message. This replaces the special-case code in
538 (invoke_main_func): Body function for scm_internal_catch; invoke
539 the user's main function, using the main_func_closure pointer to
540 decide what to pass it.
541 * root.c (struct cwdr_body_data): Remove handler_proc member.
542 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
543 (cwdr_handler): Removed.
545 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
547 * socket.h (SCM_P): update bind prototype.
548 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
550 (scm_socket): return a port, not a file descriptor object.
551 include "fports.h" and <unistd.h>
552 (scm_bind): take a port, not a file descriptor object.
553 take an extra argument for address args.
555 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
556 INADDR_NONE, INADDR_LOOPBACK.
558 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
560 * init.c: include net_db.h and not fdsocket.h.
561 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
563 * Makefile.am: corresponding changes.
564 * socket.h: renamed from fdsocket.h, fix names.
565 * net_db.h: renamed from socket.h, fix names.
566 * socket.c: renamed from fdsocket.c.
567 remove _sys from procedure names.
568 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
569 add "socket" to features list.
570 * net_db.c: renamed from socket.c.
571 remove _sys from procedure names.
572 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
573 add "net-db" to features list.
574 include "net_db.h". don't include <sys/socket.h> or
577 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
579 * tags.h (scm_tags): Removed comma at end of last enumerator.
581 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
583 Don't use GCC extensions to allocate space for debugging frames.
584 (Here he goes again! Why do we put up with this?!)
585 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
586 an scm_debug_info structure, not an in-line array of them. Add
587 'info' member, to say how many vect elements we've used, for eval
589 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
590 a new variable debug_info_end to mark the end of vect, instead of
591 the address of the 'info' pointer itself.
592 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
593 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
594 (SCM_APPLY): Explicitly allocate space for debug.vect.
595 * debug.c (scm_m_start_stack): Same, for vframe.vect.
596 * stacks.c: Adjusted for new debug frame structure.
597 (RELOC_INFO, RELOC_FRAME): New macros.
598 (stack_depth, read_frames): Use them, and new scm_debug_frame
599 element 'info', instead of magically knowing that eval frames have
600 an info pointer sitting after vect.
601 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
603 (scm_init_stacks): Formatting tweaks.
605 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
607 Give GCC more control flow information, so it can be sure that
608 variables aren't used uninitialized.
609 * error.h (scm_error, scm_syserror, scm_syserror_msg,
610 scm_sysmissing, scm_num_overflow, scm_out_of_range,
611 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
612 scm_misc_error): Tell GCC that these functions never return.
613 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
614 out the field type, call abort if SCM_ASSERT returns, to placate
616 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
617 scm_wta ever returns. We can't handle this case anyway, and this
618 gives the optimizer more information.
619 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
620 scm_wta ever returns.
622 In some cases, the code is fine, but GCC isn't smart enough to
623 figure that out; this usually happens when one variable is only
624 initialized and used when a particular condition holds true, and
625 we know that condition will never change within a given invocation
626 of the function. In this case, we simply initialize the variables
627 to placate the compiler, hopefully to a value which will cause a
628 crash if it is ever actually used.
629 * print.c (scm_iprin1): Initialize mw_pos.
630 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
631 * throw.c (scm_ithrow): Initialize dynpair.
632 * unif.c (scm_uniform_vector_ref): Initialize cra.
633 * struct.c (init_struct): Initialize prot.
634 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
636 * strports.c (scm_eval_0str): Don't return uninitialized garbage
637 if EXPR contains no expressions.
639 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
641 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
642 cause an infinite loop (???). So much for the algebraic
643 equivalency of variable-sized arrays and alloca...
645 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
647 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
648 a SCM boolean, not a C boolean.
650 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
652 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
653 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
654 rules for raising scm_mtrigger. Previously, unfortunate but not
655 unlikely circumstances could result in almost constant invokation
656 of the gc. Now, this situations should be less likely, but they
657 are not prevented completely.
659 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
661 * numbers.c (scm_fuck): Procedure removed; looks like old test
663 * numbers.h: Prototype removed.
665 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
667 * debug.h (scm_debug_frame): Change `vect' member from an in-line
668 array to a pointer, to match my Nov 21 change in eval.c.
670 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
672 * libguile.h: Added #include "libguile/backtrace.h", #include
675 * strings.c (scm_string scm_make_string scm_string_ref
676 scm_string_set_x scm_string_equal_p scm_string_append):
677 Bugfix according to scm patch from Aubrey Jaffer:
678 Corrected long-standing
679 (not (eqv? (integer->char 128)
680 (string-ref (make-string 1 (integer->char 128)) 0)))
681 bug found by John Kozak <jk@noontide.demon.co.uk>.
683 * strports.c, strports.h: Make scm_eval_0str return the value of
684 the last expression evaluated (previously, it returned void).
686 * strports.c, strports.h: New function: scm_read_0str. Does what
689 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
691 * simpos.c (scm_getenv): return #f if string can't be found in the
692 environment instead of throwing an exception, for compatibility
693 with numerous other systems.
695 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
697 * Makefile.am (.c.x): Use guile-snarf.
698 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
700 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
702 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
704 * backtrace.c (scm_display_error_message): Made non-static, and
705 renamed from display_error_message.
706 * backtrace.h (scm_display_error_message): Added extern decl.
707 * throw.c (uncaught_throw): Use it to display the error message.
709 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
711 * inet_aton.c: Use #if 0, not #ifdef 0.
713 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
715 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
716 to convert the returned value.
717 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
720 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
722 Add new interface to catch/throw, usable from C as well as
724 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
725 (scm_internal_catch): New function, replaces...
726 (scm_catch_apply): Deleted.
727 * throw.c (scm_catch_apply): Deleted; replaced with a more general
728 mechanism which is a bit more code, but can be used nicely from C
729 and implement the Scheme semantics as well.
730 (scm_internal_catch): This is the replacement; it's named after
731 the analogous function in Emacs.
732 (scm_catch): Reimplemented in terms of the above.
733 (struct catch_body_data, catch_body, catch_handler): New
734 functions, used by scm_catch.
735 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
736 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
737 support for new cwdr.
739 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
742 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
744 * acconfig.h: Added DYNAMIC_LINKING symbol.
745 * configure.in: Add option and checks for dynamic linking.
746 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
747 dynl.h: New files for dynamic linking support.
748 * Makefile.am (libguile_a_SOURCES):
750 (modinclude_HEADERS): Added "dynl.h".
751 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
753 * init.c (scm_boot_guile_1): Call
754 scm_init_dynamic_linking to initialize dynamic linking support.
756 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
758 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
759 (as we Schemers say). It needs to be global, so that I can tweak
760 it for the proper operation of unexec.
761 (scm_boot_guile_1_live): New variable, see above.
763 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
765 * guile-snarf.sh: Removed.
766 * PLUGIN/guile.libs: Added dependency for -lm.
767 * acinclude.m4: Renamed from aclocal.m4.
768 * PLUGIN/greet: Removed.
769 * Makefile.am, aclocal.m4: New files.
770 * configure.in: Updated for Automake.
772 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
774 * eval.c (scm_definedp): Use top_level_lookup_closure_var
775 and not top_level_lookup_thunk_var.
777 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
779 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
781 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
783 * eval.c (scm_definedp): Incompatibly changed to be a builtin
784 Scheme function, instead of syntax. Single argument is now a
787 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
789 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
790 scm_ra_divide): Properly terminate statements passed as arguments
791 to IVDEP macros. (Thanks to Bernard Urban.)
793 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
794 with non-constant sizes. (Thanks to Bernard Urban.)
796 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
798 It's an "eval closure", not an "eval thunk." A thunk is a
799 function of no arguments.
800 * root.h (struct scm_root_state): Renamed
801 top_level_lookup_closure_var from top_level_lookup_thunk_var.
802 (scm_top_level_lookup_closure_var): Renamed from
803 scm_top_level_lookup_thunk_var.
804 * root.c (mark_root): Uses changed.
805 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
806 * init.c (scm_start_stack): Uses changed.
807 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
808 Change scheme-visible name to *top-level-lookup-closure* from
809 *top-level-lookup-thunk*.
811 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
813 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
814 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
816 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
818 * gc.c (struct scm_heap_seg_data): Doc fixes.
820 * gc.c (scm_gc_sweep): Empty all segments' freelists before
821 sweeping. Then, prepend each segment's free cells to its
822 freelist, rather than wiping out the old value. (Thanks to Marius
825 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
826 scm_check_freelist, scm_debug_newcell): New functions and
827 variables, for debugging freelist problems.
828 * pairs.h (SCM_NEWCELL): New debugging version added.
829 * gc.h (scm_debug_newcell): Added extern declaration, used by
830 debugging version of SCM_NEWCELL.
832 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
834 On some systems <libc.h> conflicts with <unistd.h>, and should not
836 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
837 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
838 * configure.in: Call it.
839 * posix.c, filesys.c: Use its results to decide whether or not to
841 * configure, scmconfig.h.in: Rebuilt with autoconf and
844 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
846 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
847 pointer to the stdio stream before calling scm_setbuf0, so the
848 latter will be able to retrieve it. I'm surprised this didn't
849 segfault earlier. (Thanks to Christopher Lee.)
851 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
853 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
856 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
858 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
859 number of stack narrowing specifier pairs. The first specifier in
860 a pair controls inner border, the second the outer border. A
861 number means cut that number of frames, a procedure object means
862 cut until that object is found in operator position in a frame.
864 * root.c (cwdr): Bugfix.
866 * read.c: Recording of positions disabled by default.
868 * procs.c (scm_closure_p): New function.
870 * posix.c (scm_tmpnam): New function.
872 * load.c: Added #include "throw.h".
873 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
876 * load.c, load.h (scm_read_and_eval_x): New function.
878 * eval.c: Renamed debug option "deval" to "debug".
880 (scm_eval_x): `eval!' is no longer accessible from the scheme
881 level. Motivation: We can't allow operations which introduce
882 glocs into the scheme level. Guile's type system can't handle
883 these as data. Use `eval' or `read-and-eval!' as replacement.
885 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
886 SCM_CONSP since this is a macro!; Set vframe.prev to
887 scm_last_debug_frame instead of 0. In this way we can look
888 "above" the virtual start stack frame if we wish.
889 (scm_debug_hang): New function: Useful for debugging Guile in
890 certain tricky situations. Will probably be removed later...
892 * debug.h: Changed semantics of debug option "backtrace". This
893 option now only indicates whether we want automatic backtrace at
896 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
898 * ports.c: #include "filesys.h"
899 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
901 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
902 Motivation: This is system specific code which is related to file
903 I/O. It also may use select. Added code by Gary Houston to
904 detect presence of character in stdio buffers.
906 * libguile.h: #include "libguile/libpath.h"
908 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
909 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
910 SCM_SITE_DIR; Install libpath.h among the other include files.
912 * load.c, load.h (scm_sys_package_data_dir): New function.
914 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
916 * stacks.h: Bugfix: Don't use tail-array length field as stack
917 length field! This screwed GC.
919 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
921 * _scm.h: Added #ifndef around definition of macros min and max.
923 * __scm.h: Added hooks for threads to plugin to in ints protection
924 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
925 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
926 the main code in these macros duplicated and spread over multiple
927 files. Renamed SCM_THREADS_SWITCHING_CODE ->
928 SCM_THREAD_SWITCHING_CODE.
930 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
933 * guile-snarf.sh: New file.
934 * Makefile.in (inner_h_files): Added snarf.h
935 (ancillary, install, uninstall, distclean): Added actions for
937 (.c.x): Use guile-snarf.
938 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
939 (gen_c_files): Note that these depend on guile-snarf.
940 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
941 now in "snarf.h". Added #include "snarf.h" to get them.
942 * libguile.h: Added #include "snarf.h".
943 (Patches applied and tweaked by Jim Blandy.)
945 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
947 * socket.c: Use K&R style declaration for 'close'; the GNU coding
948 standards suggest against providing prototypes for system
949 functions. Thanks to Greg Troxel.
951 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
953 * strports.c (scm_eval_0str): New function.
954 #include "read.h", to get prototype for scm_read.
955 * Makefile.in (strports.o): Update dependencies.
956 * strports.h: New prototype.
958 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
959 scheme name from "int?" to "integer?". It seems to do the job.
960 * numbers.h: Rename prototype too.
961 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
964 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
965 scm_num_eq_p): Rename these according to R4RS conventions: call
966 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
967 to making libguile R4RS compliant without ice-9...
969 * load.c (scm_sys_search_load_path): Search for files under all
970 extensions listed in the %load-extensions variable. If FILENAME
971 is absolute, return it unchanged, without searching the load path.
972 (scm_loc_load_extensions): New variable, pointing to
973 %load-extensions' value cell.
974 (scm_init_load): Initialize it, and the value it points to.
975 (scm_primitive_load_path): Improve error reporting.
977 * load.c (scm_loc_load_hook): New variable, pointing to value cell
978 of new Scheme variable %load-hook.
979 (scm_primitive_load): Apply %load-hook to filename.
981 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
983 * configure.in: add tests for figuring out whether buffered data
984 is available in a FILE structure, which is needed by char-ready.
986 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
989 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
990 exceptions using misc_error instead of syserror. It seems a bit
991 odd to throw an exception if a string can't be found in the
992 environment, but it's consistent with open-file, stat etc.
993 (simpos.h): remove sys_ from getenv.
995 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
996 occurs, throw an error instead of returning errno. Return value
998 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1000 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1002 * filesys.c (scm_stat2scm): derive file type and permissions from
1003 the stat mode and append them to the returned vector.
1004 There isn't much overhead in doing this and it avoids the need to
1005 work with S_IRUSR et al. in Scheme.
1006 Define symbols scm_sym_regular etc.
1007 (scm_init_filesys): don't intern S_IRUSR etc.
1009 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1010 and s_primitive_load_path.
1012 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1014 * error.h: don't declare error symbols. prototype for scm_misc_error.
1016 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1019 * error.c: use SCM_SYMBOL to set up error keys.
1020 scm_misc_error: new procedure.
1022 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1024 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1025 between `#!' and `!#' is ignored.
1026 (skip_scsh_block_comment): New function.
1028 * feature.c (scm_set_program_arguments): New argument, FIRST.
1029 * feature.h: Update prototype.
1030 * init.c (scm_boot_guile_1): Pass new argument to
1031 scm_set_program_arguments.
1033 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1035 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1036 (scm_boot_guile): Call scm_set_program_arguments here, later than
1037 the old initialization.
1039 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1040 initialization procedure.
1041 - Delete in, out, err arguments; there are other perfectly good
1042 ways to override these when desired.
1043 - Delete result argument; this function shouldn't ever return.
1044 - Rename init_func argument to main_func, for less confusion.
1045 - Delete boot_cmd argument; main_func is more general.
1046 -Add 'closure' argument, to help people pass data to main_func
1047 without resorting to global variables.
1048 - Abort if reentered; don't bother returning an error code.
1049 - Call scm_init_standard_ports to set up the default/current
1050 standard ports; no need to pass them to scm_start_stack.
1051 - Remove code to evaluate the boot_cmd, and start the repl; let
1052 the user do something like that in main_func if they want.
1053 - Remove code to package up a return value; main_func can do any
1055 - Call exit (0), instead of returning.
1056 (scm_start_stack): Don't initialize the I/O ports here; that's
1057 weird. Delete in, out, err arguments. Move guts to
1058 scm_init_standard_ports, scm_stdio_to_port.
1059 (scm_init_standard_ports): New function, to set up current and
1060 default standard ports.
1061 (scm_start_stack, scm_restart_stack): Make these static.
1062 * init.h (scm_boot_guile): Adjust declaration.
1063 (scm_start_stack, scm_restart_stack): Remove externally
1064 visible declarations for these.
1065 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1067 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1068 written out several times in scm_start_stack.
1069 * fports.h: New declaration for the above.
1071 * feature.c (scm_set_program_arguments): New function.
1072 * feature.h: New declaration for the above.
1074 * ports.c: Formatting tweak.
1076 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1078 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1079 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1080 for obtaining the address of a car or cdr field. Motivation:
1081 &SCM_CXR make assumptions about the internal structure of the
1084 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1085 Motivation: see SCM_CXRLOC.
1087 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1088 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1089 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1090 Motivation: Safer use. Some other macros are defined in terms of
1091 these operations. If these are defined using the SCM_SETCXR
1092 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1093 to inefficiency and an <e1> with side-effects could potentially
1094 break. Also, these particular operations are heavily utilized in
1095 the garbage collector. In unoptimized code there will be a
1098 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1099 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
1100 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
1101 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
1102 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
1103 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1104 vports.c: Cleaned up use of pairs: Don't make any special
1105 assumptions about the internal structure of selectors and
1106 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1107 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1108 (Among other things, this change makes it easier to build Guile
1109 with certain compilers which have problems with casted lvalues.)
1111 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1113 * stacks.c: Improve selection of relevant stack frames when making
1114 a stack object. Introduce one level of indirection in the stack
1115 object to make it possible to "narrow" to a certain region of the
1116 stack. This facilitates making use of more clever algorithms (not
1117 implemented) for selecting relevant frames and gives a cleaner
1118 design since selection of frames can be done independently of
1119 extraction of frames from the real stack.
1120 (scm_stack_id): Also take #t as argument which means look at
1123 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1124 Turn n_tail into an integer directly representing current number
1125 of frames in stack. Add field tail.
1127 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1129 * debug.c (scm_make_memoized): Made it available at scheme level.
1130 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1131 SCM_NIMP before applying heavier predicates in argument checking.
1132 (scm_local_eval): Also take memoized object as argument.
1134 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1135 aren't created with zero length, but should such a strange
1136 creature suddenly turn up...
1138 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1140 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1141 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1143 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1145 * variable.c (scm_make_variable): Make the name hint optional, as
1147 (anonymous_variable_sym): Renamed from variable_sym. All uses
1150 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1151 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1152 of scm_primitive_load_path was also changed to
1153 "primitive-load-path", from "%try-load-path". Callers changed.
1154 We'd like to respect the convention that a function named
1155 "try-mumble" should behave just like the function called "mumble",
1156 but return #f instead of signalling some error.
1157 * load.h: Rename prototypes.
1159 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1161 * print.c (make_print_state, grow_print_state), print.h: Modified
1162 the print state representation: Don't use a tail array for
1163 recording of circular references. Resizing of the print state
1164 structure invalidates the print state pointer. To avoid passing
1165 around an indirect print state reference to all printing
1166 functions, we instead let the print state reference a resizable
1169 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1171 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1172 Don't crash when passed an improper list terminated by a
1173 non-immediate value.
1175 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1177 Allocate data for structures on an eight-byte boundary, as
1178 required by the tagging system.
1179 * struct.c (alloc_struct): New function.
1180 (scm_make_struct, scm_make_vtable_vtable): Call it.
1181 * struct.h (scm_struct_n_extra_words): Bump to 3.
1182 (scm_struct_i_ptr): New "field".
1183 * gc.c (scm_gc_sweep): When we need to free the data, use the
1184 information stored by alloc_struct to find the beginning of the
1185 block allocated to the structure, so we can free it.
1187 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1189 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1192 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1193 (scm_debug_info): New member: id.
1195 * stacks.c: Stacks are now represented as structs; Stacks have an
1196 id given to them by `start-stack'.
1197 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1199 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1200 Changed stack representation.
1202 * debug.c (scm_procedure_name): Try procedure property `name' for
1203 compiled closures aswell.
1205 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
1207 * eval.c: scm_i_name moved to gsubr.c
1208 (scm_m_define): Record names of all kinds of procedure
1209 objects. (Earlier, only closures were recorded.)
1211 * procprop.h: Added declaration of scm_i_name.
1213 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1214 (scm_make_gsubr): Record names of compiled closures.
1216 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1218 * debug.c, debug.h: Removed obsolete code.
1220 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1221 stacks.c: Renamed regs --> scm_contregs.
1223 * print.c (scm_free_print_state): Cleanup print state before
1224 returning it to pool. It is better to do it here than in
1225 scm_prin1 since scm_prin1 is called often.
1227 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1228 s_set_source_property_x): Check that first argument is a pair or a
1231 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1232 scm_i_line, scm_i_column and scm_i_breakpoint global.
1234 * init.c: Added #include "backtrace.h" and #include "stacks.h".
1235 (scm_boot_guile_1): Added calls to scm_init_backtrace and
1238 * debug.h: Added debug object smob declaration and macro
1241 * configure.in: Build with backtrace.o and stacks.o if debug
1244 * Makefile.in: Added entries for new files: backtrace.c,
1245 backtrace.h, stacks.c and stacks.h.
1247 * symbols.c (scm_sym2ovcell): Fixed documentation.
1249 * _scm.h (min, max): Added.
1251 * async.c: Moved `min' macro to _scm.h.
1253 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1254 SCM_BACKTRACE_INDENT.
1256 * eval.c: Added new debug options `maxdepth' and `indent'.
1258 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
1260 * print.h: Added selector SCM_PRINT_STATE.
1262 * print.c: New functions: scm_make_print_state,
1263 scm_free_print_state.
1265 * print.h: Added declarations for scm_make_print_state,
1266 scm_free_print_state.
1268 * debug.c (scm_m_start_stack): New acro.
1270 * debug.h: Small cleanup.
1272 * init.c (scm_boot_guile_1): Moved scm_init_debug below
1275 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

1295 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
1296 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
1297 declare functions with prototypes. (Patch thanks to Marius
1300 More prototype-related changes from Marius Vollmer:
1301 * gdb_interface.h: Wrapped header file in #ifdef/#endif
1302 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
1303 * ports.h (ptobfuns): Added prototypes. This means some casting in
1305 * fports.c: Added casts for initializations, since the functions
1306 are defined to take FILE * as their stream argument, not SCM.
1307 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
1308 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
1309 to `char *str_data' to conform to prototype.
1311 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1313 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
1315 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
1317 * stime.c, stime.h: use SCM_P method.
1319 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1321 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
1322 be given at least two arguments. Insist that lst's last element
1323 be a list, but don't make any requirements of its predecessors.
1325 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1327 * eval.c (scm_nconc2last): Revert last change; there seems to be
1328 other stuff going on here.
1330 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1332 * eval.c (scm_nconc2last): Make sure that each element of lst
1333 (which is a list of argument lists, except for the tail) is a
1334 proper list, i.e., finite and terminated by '().
1336 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1338 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
1341 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
1342 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
1345 * vectors.c (scm_make_vector): Fill vectors with the undefined
1346 value, to help make Guile Scheme code more portable to other
1349 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
1350 * symbols.h, tags.h: Doc fixes.
1352 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
1354 * async.c (scm_take_signal): Doc fixes.
1356 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
1358 * numbers.c (scm_divbigint): When the remainder is zero, we don't
1359 want to subtract it from the modulus; we just want to leave it
1362 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
1364 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
1367 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
1369 * throw.c (scm_catch_apply): Finished implementation of
1372 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
1374 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
1376 (scm_init_filesys): set "i/o-extensions" feature.
1379 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
1381 * Makefile.in (root.o): Correct dependencies.
1383 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
1385 * Makefile.in: Added dependency entry for root.o.
1387 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
1388 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
1390 * init.c (scm_start_stack): Set initial root continuation number
1393 * procs.c: New function: scm_thunk_p.
1395 * procs.h: Added declarations of scm_thunk_p.
1397 * root.c: Renamed `call-with-new-root' -->
1398 `call-with-dynamic-root'.
1399 (cwdr): Removed allocation of new root state. This should be done
1400 separately by use of scm_make_root.
1401 (scm_apply_with_dynamic_root): New function: Does what it
1402 sounds like. Needed when spawning threads.
1404 * root.h: Added member last_debug_frame to root state.
1405 Added #include "libguile/debug.h"
1407 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
1408 arguments. The motivation is that code in root.c needs catch
1409 functionality, and we want to avoid code duplication.
1410 New functions: scm_catch, scm_lazy_catch. These are wrappers for
1411 scm_catch_apply. scm_lazy_catch is intended to introduce catch
1412 handlers that run without popping the stack into the dynwind
1415 * throw.h: Added prototypes for scm_catch_apply and
1418 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1420 * root.h (scm_root, scm_set_root): Decouple thread support details
1421 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
1422 SCM_SET_THREAD_LOCAL_DATA.
1424 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
1425 and tortoise scanning loop.
1427 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
1429 * Makefile.in: Rebuild dependencies.
1431 * libguile.h: #include "libguile/print.h" before "smob.h", since
1432 the latter uses the print_state structure.
1434 * throw.c (scm_ithrow): Use the correct variable when checking to
1435 see if a given element of scm_dynwinds is a valid catch.
1437 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
1438 structure, abort; don't just silently ignore the garbage.
1440 * _scm.h: #include "print.h" here, since it seems to be used just
1442 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
1443 strports.c, unif.h: Don't #include "print.h".
1445 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1447 * feature.h (scm_loc_features): Removed external declaration.
1448 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
1450 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1452 * feature.c (scm_init_feature): Added threads feature (needs to be
1453 initialized here, since features doesn't exist when
1454 scm_init_threads is called).
1456 * libguile.h: Added #include "libguile/../threads/threads.h".
1457 (This is a kludge to get thread support working. This should be
1460 * configure.in, acconfig.h: Added flags for thread support.
1462 * scmsigs.c: Define `signal' to be `pthread_signal' if using
1465 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
1466 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
1469 * _scm.h: Added conditional #include "threads.h"
1471 * __scm.h (SCM_ASYNC_TICK): Added call to macro
1472 SCM_THREADS_SWITCHING_CODE.
1474 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
1475 allocate the basic dynamic root object.
1476 (scm_boot_guile): Added call to scm_init_root.
1478 * root.c, root.h: Added root smob.
1479 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
1480 functions: Implements dynamic roots mostly according to spec in
1481 SCM manual. Main difference is that the second argument is a
1482 throw handler rather than an error "thunk".
1484 * root.h: Added declaration of scm_init_root.
1486 * root.c: Added #include "genio.h", #include "smob.h", #include
1487 "pairs.h", #include "throw.h", #include "dynwind.h", #include
1489 (scm_init_root): Added #include "root.x".
1491 * throw.c: Added #include "stackchk.h"
1492 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
1493 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
1494 can be used in scm_call_with_new_root; Added reenabling of stack
1495 checking when catching a throw.
1497 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
1499 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
1501 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
1502 element is not found, as per R4RS.
1504 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1506 * list.c: Doc fixes throughout.
1508 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1510 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
1511 declare the char * to be const. Avoids a warning in rgx.c.
1513 * ports.h: spelling fix.
1515 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
1518 * load.c (scm_sys_try_load_path): throw an error if file not found
1519 (like it says it in NEWS).
1521 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1523 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
1524 PROPS slot to '(), not #f; it's an empty alist.
1526 * throw.h, throw.c: Use SCM_P instead of #if hair.
1528 Remove special support for uncaught throws; see throw.c for
1530 * throw.c (uncaught_throw): New function.
1531 (scm_ithrow): Call uncaught_throw if we don't find a throw
1532 target; don't mess with scm_bad_throw_vcell.
1533 (scm_bad_throw_vcell): Variable deleted.
1534 (scm_init_throw): Don't initialize it.
1536 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
1539 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1541 * numbers.c (scm_istr2int): If the number is short (as most
1542 numbers are), just call scm_small_istr2int to deal with it.
1543 (scm_small_istr2int): New function, created by un-#ifdefing the
1544 non-bignum version of scm_istr2int and renaming it.
1546 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
1548 * load.c (scm_sys_try_load): don't check whether value returned
1549 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
1550 Change the Scheme name from %try-load to primitive-load.
1552 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
1553 Can avoid passing a message, allowing it to be derived in the
1554 error handler (e.g., if we want to throw to the key both from
1557 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
1559 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
1560 references now have a new appearance which is more compact and
1561 also gives a clue about what the target of the reference is.
1562 By setting parameters in the print state, more fancy printing can
1563 be achieved. This is used by the (not yet commited) backtrace
1566 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
1568 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
1571 * print.c: Added #include "struct.h". Removed function
1574 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
1575 scm_iprin1. Removed prototype for scm_prlist.
1577 * arbiters.c (prinarb),
1578 async.c (print_async),
1579 debug.c (prindebugobj, prinmemoized),
1580 eval.c (prinprom, prinmacro),
1581 filesys.c (scm_fd_print, scm_dir_print),
1583 mallocs.c (prinmalloc),
1584 numbers.c, numbers.h (scm_floprint, scm_bigprint),
1585 smob.h (scm_smobfuns),
1586 srcprop.c (prinsrcprops),
1588 unif.c, unif.h (scm_raprin1, rapr1),
1589 variable.c (prin_var): Changed argument `int writing' to
1590 `scm_print_state *pstate'.
1592 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
1593 that it will be called before scm_init_print.
1595 * print.c (scm_prin1): Print states are now allocated when calling
1596 scm_prin1 and then passed around to all printing functions as an
1597 argument. A cache `print_state_pool' enables reuse of print
1599 (scm_make_print_state): New function.
1600 (scm_iprin1): Adaption to print states.
1601 (scm_iprlist): An initial "hare and tortoise" scan brings down
1602 time complexity to O (depth * N). (Better time complexity will be
1603 achieved when the printing code is completely rewritten.)
1605 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1607 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
1608 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
1609 it gets done whether or not the cache variable has a value.
1611 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
1613 Distinguish #f and ().
1614 * __scm.h: #undef SICP.
1615 * pairs.h (SCM_EOL): Delete this definition, equating it with
1617 * tags.h (SCM_EOL): Give it a new definition here; I think I found
1618 the value it used to have. Doc fixes, too.
1620 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
1622 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
1623 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
1624 Lord's implementation of structs, allowing for tail arrays as
1625 described in the manual. Also fixed some bugs. (Both the interface
1626 and the implementation should be improved.)
1628 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
1630 * print.c, print.h: Closures now print like #<procedure foo (x)>.
1631 People who whish to see the source can do `(print-enable 'source)'.
1632 Removed #ifdef DEBUG_EXTENSIONS.
1634 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1636 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
1637 integer (assuming for now accepting an integer is a good thing).
1639 * error.c, fports.c: replace use of %S in lgh_error args with %s.
1640 %S will be used instead for write'ing arguments.
1642 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
1643 asserts. fix a few other asserts.
1644 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
1645 scm_uniform_vector_ref, scm_array_set_x,
1646 scm_dimensions_to_unform_array): change args in
1647 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
1648 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
1649 scm_substring_fill_x): likewise.
1650 gsubr.c (scm_gsubr_apply): likewise.
1651 eval.c (SCM_APPLY): likewise.
1653 * eval.c (4 places): replace scm_everr with lgh_error or
1656 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
1657 scm_memory_error): new procedures.
1658 scm_everr: deleted. can use scm_wta, dropping first two args.
1659 scm_error: convert NULL subr to SCM_BOOL_F.
1661 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
1664 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
1667 * error.c, error.h: new error keys: scm_arg_type_key,
1668 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
1670 scm_wta: reimplement using lgh_error instead of scm_everr.
1672 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
1674 * gdbint.c: scm_lread now has one more argument.
1676 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
1677 scm_port_\1; Added mutator scm_set_port_filename_x (used when
1678 loading source from non-file ports, which, e. g., happens when
1679 using the Emacs interface).
1681 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
1684 * read.c: Added code for recording of positions of source code
1685 expressions; New functions: recsexpr, scm_lreadrecparen;
1686 _scm_make_srcprops --> scm_make_srcprops
1687 (scm_flush_ws): Removed updating of positions counters. This work
1688 is already done by scm_gen_getc
1690 * read.h: Added prototype for scm_lreadrecparen
1692 * print.c: Added #include "alist.h"
1694 * eval.c: Added #include "hash.h"
1696 * eq.c: Added #include "ramap.h"
1698 * options.c: Documentation fixes.
1700 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
1701 (scm_init_srcprop): Adjusted size of initial source-whash. Name
1702 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
1703 --> scm_make_srcprops
1705 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
1706 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
1707 function calls in the definition of the whash access macros.
1709 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
1711 * init.c (scm_boot_guile): Add level of indirection to
1712 scm_boot_guile_1() to ensure that stack base pointer is properly
1713 initialized. There was no guarantee that variable i was the
1714 highest/lowest variable on stack (i.e. the call frame of
1715 scm_boot_guile was not completely protected from gc).
1717 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
1719 * ports.h (scm_port_table): put back file_name, it will be used to
1720 support debugging. Undo related changes in fports.c, ioext.c,
1723 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1725 * ports.h (scm_port_table): remove file_name member for now, it seems
1727 * fports.c (scm_open_file): don't set file_name in PTAB.
1728 (prinfport): don't use file_name in PTAB.
1729 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
1730 * ports.c (scm_add_to_port_table): don't intialize file_name.
1731 (scm_port_file_name): remove for now.
1732 * gc.c (scm_gc_mark): don't mark PTAB file_name.
1734 * fports.h (scm_mkfile): prototype deleted.
1735 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
1737 * debug.c, unif.c: use scm_out_of_range instead of
1738 wta for range errors (ASSERT still needs work).
1740 * error.c, error.h (scm_out_of_range): new procedure.
1742 * error.c, error.h (scm_out_of_range_key): new key.
1744 * posix.c (scm_sync): #else was missing.
1746 * error.c, error.h: append _key to names scm_num_overflow and
1749 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
1750 of consing an empty list.
1751 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
1752 of macros, saves code and string space.
1753 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
1754 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
1755 lower case. Rename scm_syserror_m to scm_syserror_msg.
1756 error.h: prototypes for new procedures.
1758 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
1760 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
1762 * error.c, error.h: setup scm_num_overflow key.
1764 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
1765 Remove definition of SCM_OVSCM_FLOW.
1767 * fports.c (scm_open_file): use SCM_SYSERROR_M.
1769 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
1770 explicit message and args.
1772 * error.c, error.h, __scm.h: change system_error_sym to
1775 * error.c (system_error_sym): remove leading %% from the Scheme name
1778 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
1780 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1782 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
1783 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
1784 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
1785 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
1786 renamed. (These were introduced by unsupervised name
1789 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1791 * print.c: Added code for detection of circular references during
1792 printing. (init_ref_stack, grow_ref_stack): New functions. Added
1793 a hook for printing of closures (accessible via print options).
1794 This leads to a split of calls to scm_iprin1 into two classes:
1795 elementary print operations (e. g. the code which prints a smob)
1796 still use scm_iprin1 while top level calls (like scm_display) use
1797 scm_prin1. scm_prin1 begins by clearing the data structure used
1798 to record reference information.
1800 * print.h: Added declarations of scm_prin1 and scm_prlist.
1802 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
1804 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
1806 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
1808 * error.c (err_head): scm_iprin1 --> scm_prin1
1810 * debug.c: Adjusted header comment.
1814 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1816 * strerror.c: Doc fix.
1818 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1820 * gdbint.c (gdb_read): Now possible to run during GC.
1821 (unmark_port, remark_port): New functions.
1823 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
1825 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
1826 of allocating a new string object. Also, increase size by
1827 the factor 2 instead of 1.5.
1829 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
1831 * __scm.h (SCM_P): Corrected to run under traditional C.
1833 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
1836 * async.c: Calls to scm_sysintern corrected.
1838 * async.h (scm_async_clock): Redundant declaration removed.
1840 * continuations.c (scm_dynthrow): Redundant declaration removed.
1842 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
1843 Definition typos corrected.
1845 * debug.h: Missing declarations of functions in debug.c added
1848 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
1849 Missing declarations to functions in eval.c added.
1851 * filesys.c: Possibly uninitialized variable rv.
1853 * gc.h (scm_object_addr, scm_unhash_name): Missing
1854 declarations of functions defined in gc.c added.
1856 * genio.c: Possible typos str_data -> wstr_data. ???
1858 * genio.c: Possibly unintended shadowing of local variable
1859 `int c' (gotos out of scope of inner `c'). ???
1861 * init.c: Uninitialized `SCM last' may be used.
1863 * ioext.h: (scm_sys_isatty_p): Typo.
1865 * list.h (scm_list_head): Missing prototype for function in
1868 * numbers.c (scm_two_doubles): Changed from extern to static
1869 (is used only within numbers.c).
1871 * numbers.h: Repeated declarations removed.
1873 * ports.h (scm_close_all_ports_except): Declaration for the
1874 function defined in ports.c added.
1876 * posix.h: Missing declarations added.
1878 * procs.h (scm_make_subr_opt): Missing declaration added.
1880 * socket.h (scm_sys_gethost): Missing declaration added.
1882 * socket.h: Redundant declarations removed (they are in fdsocket.h).
1884 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
1885 Missing declarations added.
1887 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
1889 * struct.c: Uninitialized variable `SCM answer' may be used.
1891 * unif.c (l2ra): Declaration prototype.
1893 * unif.c (scm_array_equal_p): Dummy definition removed (it is
1894 defined in ramap.c).
1896 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
1897 Redundant declarations removed (they are in ramap.h).
1899 * variable.h (scm_make_udvariable,
1900 scm_make_undefined_variable): Declaration corrected to
1901 correspond variable.c.
1903 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
1904 Missing declarations added.
1906 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
1908 * Makefile.in (distclean): Don't forget to delete fd.h.
1910 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1912 * fd.h.in, tags.h: Trivial cleanups.
1914 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
1915 marksweep.h just declared functions from gc.c.
1916 * gc.h, libguile.h: Don't #include "marksweep.h".
1917 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
1918 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
1919 dependencies updated.
1921 * libguile.h: Don't #include "files.h"; it's been deleted.
1923 * files.c (scm_sys_delete_file): Moved to filesys.c.
1924 File is now empty; deleted.
1926 * filesys.c: scm_sys_delete_file is now here. Remove
1927 #if's; they seem to rely on remnants of an old portability
1928 regimen. If the problems come up again, solve them properly,
1929 using autoconf. Specifically: Don't test M_SYSV, and #define
1930 remove to be unlink if it's #defined; don't use remove just
1931 because HAVE_STDC_HEADERS is #defined.
1932 * filesys.h: Add declarations for scm_sys_delete_file.
1933 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
1934 files.o, files.h, files.c, and files.x.
1935 * init.c: Don't #include "files.h", and don't call scm_init_files.
1937 Use SCM_P instead of PROTO; the latter intrudes on the user's
1939 * params.h: Deleted; definition of SCM_P moved to...
1940 * __scm.h: ... here, where it replaces PROTO macro.
1941 * libguile.h, smob.h: Don't #include "params.h".
1942 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
1943 smob.h: Fix prototypes accordingly.
1944 * Makefile.in: Update dependencies.
1945 (inner_h_files): Remove params.h.
1947 * gc.c: #include "gc.h"; every module should include its header,
1948 to let the compiler cross-check the declarations against the
1951 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
1952 simpos.h: #include "libguile/__scm.h".
1954 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
1956 * init.c: Don't forget to #include smob.h and init.h.
1957 * Makefile.in: Dependencies updated.
1959 * smob.h: Use PROTO instead of #if __STDC__.
1961 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
1963 * __scm.h: Doc fixes.
1965 * __scm.h, libguile.h: Use "quotes" in the #includes, not
1966 <angles>; this allows `make depends' to work properly.
1968 * libguile.h: #include smob.h and pairs.h before the others; they
1969 define typedefs used by other headers.
1971 C files should #include only the header files they need, not
1972 libguile.h (which #includes all the header files); the pointless
1973 recompilation was wasting my time.
1974 * Makefile.in (all .o dependency lists): Regenerated.
1975 * libguile.h: Don't try to get a definition for size_t here...
1976 * __scm.h: Do it here.
1977 * _scm.h: Since this is the internal libguile header, put things
1978 here that all (or a majority) of the libguile files will want.
1979 Don't #include <libguile.h> here; that generates dependencies on
1980 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
1981 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
1982 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

2079 * weaks.c: Get "weaks.h".
2081 * stackchk.h: #include "libguile/debug.h",
2083 * print.h, read.h: #include "options.h", since everyone who uses
2084 either of these files will need that.
2086 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2087 anyone who uses this file will need them to define the smob
2088 printing functions. Also, get markers.h, since people will need
2089 to #define the mark functions.
2091 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2092 * ports.h: ... to here.
2094 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2095 don't rely on archaic C default type rules.
2097 * fports.h: #include "libguile/ports.h", since you need that in
2098 order to parse this.
2100 * genio.h: #include "libguile/print.h", because you need that to
2101 parse this; don't bother #including "ports.h", since print.h gets
2104 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2106 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2107 this; it's now a reference to an element of *scm_root.
2109 * debug.h: Don't #include "options.h"; the compiler won't be able
2110 to find that once the headers are installed; instead, #include
2111 "libguile/options.h".
2112 * gc.h: Same, with marksweep.h.
2113 * mbstrings.h: Same, with symbols.h.
2114 * scmhob.h: Same, with _scm.h.
2115 * smob.h: Same, with params.h.
2117 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2118 C files; there's no need for this, and it forces recompilations
2121 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2123 * error.c (scm_error): declare scm_error_callback.
2125 * error.h: prototype for scm_error_callback.
2127 * __scm.h: define lgh_error.
2128 (SCM_SYSERROR): redefine using lgh_error.
2130 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2132 * error.c (scm_error): new procedure.
2134 * error.h: prototype for scm_error.
2136 * Makefile.in (install): install scmconfig.h from the current
2137 directory, not $(srcdir).
2139 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2141 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2142 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2143 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
2144 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
2145 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
2146 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2147 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2148 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2149 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2150 vports.h, weaks.h: #include "libguile/__scm.h", not
2151 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2152 dependencies are within libguile properly.
2154 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2156 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2157 when scmconfig.h doesn't exist.
2159 * load.c (scm_sys_try_load): Correct spelling.
2161 * feature.c (scm_loc_features): Make this static.
2163 * Makefile.in (libpath.h): Omit trailing slash from path. We
2164 shouldn't require it of users, so why put it here?
2166 Move code to initialize and search %load-path from ice-9 to C
2167 code, so we can use the load-path to find the ice-9 boot code;
2168 this makes it easier to run Guile without installing it. See
2169 corresponding changes in guile/Makefile.in.
2170 * feature.c: Move stuff concerned with the load path to load.c.
2171 (scm_compiled_library_path): Deleted.
2172 Don't #include libpath.h here.
2173 * feature.h: Don't mention scm_compiled_library_path.
2174 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2175 <sys/stat.h>, and <unistd.h> (if present).
2176 (R_OK): #define if the system hasn't deigned to.
2177 (scm_loc_load_path): New variable.
2178 (scm_init_load_path, scm_sys_search_load_path,
2179 scm_sys_try_load_path): New functions.
2180 (scm_init_load): Initialize scm_loc_load_path to point to the
2181 value cell of the Scheme %load-path variable.
2182 * load.h: Add declarations for scm_sys_search_load_path,
2183 scm_sys_try_load_path.
2184 * init.c: Call scm_init_load_path.
2185 * Makefile.in (feature.o, load.o): Dependencies updated.
2187 * load.c, load.h: Rewrite using PROTO macro.
2189 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2191 * gc.c (scm_cellp): New function: C predicate to determine if an
2192 SCM value can be regarded as a pointer to a cell on the heap.
2194 * gc.h: Added declaration of scm_cellp.
2196 * gdb_interface.h: New file: The GDB interface header from the GDB
2199 * gdbint.c: New file: GDB interface.
2201 * gdbint.h: New file: GDB interface.
2203 * libguile.h: Added #include <libguile/gdbint.h>.
2205 * init.c (scm_boot_guile): Added scm_init_gdbint.
2207 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2208 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2209 found if object files and source are kept separate).
2211 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2213 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2215 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2217 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2218 TK_SRC_DIR; they're not relevant any more.
2220 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2221 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2223 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2225 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2226 search path, so we can find the <libguile/MUMBLE.h> headers.
2228 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2230 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2231 implicit in the .c.o rule.
2232 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2235 Put the library path in a header file, instead of passing it on
2236 the command line in every compilation.
2237 * Makefile.in (libpath.h): New target.
2238 (feature.o): Depend on libpath.h.
2239 (clean): Delete libpath.h.
2240 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2241 * feature.c: ... #include "libpath.h" here.
2242 * .cvsignore: Ignore libpath.h.
2244 Don't install the unwashed masses of Guile header files in the
2245 main #include path; put most of them in a subdirectory called
2246 'libguile'. This avoids naming conflicts between Guile header
2247 files and system header files (of which there were a few).
2248 * Makefile.in (pkgincludedir): Deleted.
2249 (innerincludedir): New variable; this and $(includedir) are enough.
2250 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
2251 (installed_h_files): Divide this up. Now this variable lists
2252 those header files which should go into $(includedir) (i.e. appear
2253 directly in the #include path), and ...
2254 (inner_h_files): ... this new variable says which files appear in
2255 a subdirectory, and are referred to as <libguile/mumble.h>.
2256 (h_files): List them both.
2257 (install): Create innerincludedir, not pkgincludedir. Put
2258 the installed_h_files and inner_h_files in their proper places.
2259 (uninstall): Corresponding changes.
2260 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2261 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2262 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
2263 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
2264 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
2265 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2266 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2267 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2268 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2269 vports.h, weaks.h: Find __scm.h in its new location.
2270 * __scm.h: Find scmconfig.h and tags.h in their new locations
2271 (they're both "inner" files).
2273 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
2275 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
2277 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2279 * posix.c: Doc fixes.
2281 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
2283 * socket.c: Don't include a prototype for inet_aton; just use a
2284 K&R style declaration, to avoid warnings but minimize the chance
2285 of conflicts with the system.
2287 On NextStep, <utime.h> doesn't define struct utime, unless we
2288 #define _POSIX_SOURCE before #including it.
2289 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
2290 * acconfig.h: New comment text for above CPP symbol.
2291 * configure.in: Call it.
2292 * posix.c: #define _POSIX_SOURCE if it seems necessary.
2294 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
2296 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
2297 testing for __EMX__.
2299 * posix.c: #include <libc.h>, if it exists.
2301 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
2302 don't even know if the latter exists.
2304 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
2305 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
2306 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
2308 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
2310 (scm_init_posix): Use them when initializing the Scheme constants
2313 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2315 * Makefile.in (libdir, includedir, bindir): Use the
2316 autoconf-supplied values, instead of deriving them ourselves.
2317 (pkgincludedir, datadir, pkgdatadir): New variables.
2318 (install, uninstall): Put the header files in a special
2319 subdirectory, not in the main search path.
2321 * Makefile.in (ALL_CFLAGS): Provide the proper value for
2322 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
2324 * Makefile.in (IMPLPATH): Deleted; never used.
2326 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
2327 on the Tcl/Tk source any more.
2328 (INCLUDE_CFLAGS): Remove references to the above.
2330 * Makefile.in (version.o): Corrected dependencies.
2332 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
2334 * libguile.h: #include "version.h"
2336 * init.c (scm_boot_guile): Call scm_init_version.
2337 * gscm.c (gscm_run_scm): Call scm_init_version.
2339 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
2340 GUILE_VERSION): AC_DEFINE these.
2341 (acconfig.h): #undef the above symbols.
2343 * Makefile.in (libobjs): Add version.o.
2344 (installed_h_files): Add version.h.
2345 (c_files): Add version.c.
2346 (gen_c_files): Add version.x.
2347 (version.o): New rule.
2348 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
2349 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

2357 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
2358 weaks.o): Add version.h to dependency lists.
2359 (markers.o): Remove duplicate rule.
2361 * version.h: New file.
2363 * version.c: New file.
2365 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2367 * symbols.c (scm_strhash): scm_downcase is now a function, not an
2368 array; use it appropriately. Since GCC is quite happy to
2369 subscript functions, it never warned us about this; we should use
2370 -Wpointer-arith in the future. I guess we never tested
2373 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2375 * socket.c: Doc and copyright fixes.
2377 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2379 * debug.c: Fixed and improved gdb support.
2381 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2383 * socket.c: Added declaration of inet_aton to avoid compiler
2384 warning. (Hope this solution is correct.)
2386 * stime.c: Added declaration of ftime. (This is missing in
2389 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
2391 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2393 * Makefile.in (c_files): add strerror.c.
2395 * strerror.c: new file from Emacs' sysdep.c.
2396 maybe configure should also check for sys_errlist.
2398 * configure.in (AC_REPLACE_FUNCS): add strerror.
2400 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2402 * debug.c (scm_init_debug): Added initialization for
2403 scm_evaluator_traps.
2405 * debug.h, debug.c: Various name changes.
2406 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
2407 "debug-options-interface". See commentary in options.c.
2409 * options.h, options.c: Options now have documentation strings.
2410 Also added a long explanatory commentary.
2412 * eval.c, print.h, print.c, read.h, read.c: Modifications to
2415 * gscm.c, init.c, root.c, throw.c: Bug fixes:
2416 last_debug_info_frame is now updated in all cases.
2418 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
2421 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2423 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
2424 Added option STACK_CHECKING.
2426 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
2428 * Makefile.in: Added {debug,options,srcprop}.{h,c}
2430 * __scm.h: Removed symbols for debugging support.
2432 * acconfig.h: Added symbols for debugging support.
2434 * configure.in: Added user option for debugging support.
2435 --enable-debug will include the debugging code into libguile.a.
2437 * continuations.c (scm_make_cont): Enlarged the #if 0 around
2438 scm_relocate_chunk_to_heap.
2440 * debug.c: New file: low-level debugging support. It also
2441 includes support for debugging with gdb. (The extensions to gdb
2442 are written by Per Bothner at Cygnus.)
2444 * debug.h: New file: low-level debugging support.
2446 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
2447 argument pairs. Extensive modifications to the debugging
2448 evaluator. Added "SECTION:" commentaries to clarify what happens
2449 when, during double compilation. Renamed EVALIMP --> EVALIM.
2450 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
2451 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
2452 the beginning of the file. New procedure: scm_unmemocopy.
2453 Added some global state variables needed by the debugging
2454 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
2455 check_entry, check_apply, check_exit, debug_options and
2456 evaluator_traps. New acro: undefine.
2458 * eval.h: Renamed EVAL --> XEVAL.
2460 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
2461 --> scm_make_weak_key_hash_table.
2463 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
2464 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
2466 * libguile.h: Conditionally include debug.h
2468 * objprop.c (scm_object_properties, scm_set_object_properties_x):
2469 scm_object_properties shouldn't return handle. `handle' now gets
2470 initialized in scm_set_object_properties_x. scm_object_properties
2471 doesn't any longer create an entry in scm_object_whash.
2473 * options.c: New file: handling of run time options.
2475 * options.h: New file: handling of run time options.
2477 * posix.c (scm_getpgrp): Cast pointer to getpgrp.

2498 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2500 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
2502 * libguile.h: #include "objprop.h"; I guess this was forgotten.
2504 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
2505 and should be called by the final client.
2507 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
2509 * gc.h: Use the PROTO macro when declaring functions.
2510 * gc.c: Use the PROTO macro when declaring static functions.
2511 Remove the CPP hair around function definitions.
2513 * gc.c (scm_init_storage): Initialize scm_asyncs.
2515 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
2516 preprocessor symbol; "__scm.h" is where it might get #defined.
2517 * __scm.h: Similar: #include <scmconfig.h> before testing
2520 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
2522 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
2524 * init.c (scm_boot_guile): Add init_func argument; call
2525 (*init_func) instead of calling scm_appinit; it's ucky to
2526 hard-code names for the user's procedures.
2527 * init.h (scm_boot_guile): Adjust declaration.
2529 * __scm.h (PROTO): New macro, for declaring functions with
2532 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
2533 eliminate all the __STDC__ conditionals.
2534 (scm_boot_guile): Add declaration.
2535 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
2536 Remove __STDC__ conditionals around function definitions; the
2537 declarations in init.h will provide the same information, more
2540 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
2541 complain about it in the error message; the error message is
2542 adequate without that note, and there's nothing the user can do
2545 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
2547 * Makefile.in (ancillary): Drop def.sed.
2549 * posix.c (scm_init_posix): Use numeric values, rather than
2550 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
2551 F_OK. The symbols aren't available on some systems, and I'm
2552 pretty sure their values are fixed by common widespread practice.
2553 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
2555 More functions unavailable on some systems.
2556 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
2557 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
2559 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2560 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
2561 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
2562 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
2563 stub that signals an error as the #else.
2565 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
2567 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
2569 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
2571 * unif.c: include ramap.h.
2573 * read.c (endif): case_insensative_p renamed case_insensitive_p.

2577 * ports.c: include sys/ioctl.h.
2579 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
2581 * configure.in: check for sys/ioctl.h.
2583 * ports.c: include <malloc.h> not "malloc.h".
2585 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2587 * fports.c: remove ttyname and tmpnam declarations.
2589 * posix.c: fewer ttyname declarations.
2591 * fports.c: include <string.h> not "string.h".
2593 * init.c, ioext.c: include string.h and unistd.h.
2595 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2597 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
2598 genio.c, simpos.c, vports.c: include string.h.
2600 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
2602 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
2604 (scm_addr_buffer_size): change type from scm_sizet to int.
2605 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
2606 from scm_sizet to int.
2608 * error.c: include unistd.h.
2610 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
2613 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
2615 * __scm.hd, def.sed: deleted.
2617 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
2619 Changes for NeXT, suggested by Robert Brown.
2620 * configure.in: Call AC_TYPE_MODE_T.
2621 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
2622 NeXT. Put header file list in alphabetical order.
2623 * configure, scmconfig.h.in: Regenerated.
2624 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
2626 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
2629 * acconfig.h: New file, providing documentation for the CPP
2630 symbols defined in configure.in
2631 * acconfig-1.5.h: Removed; superceded by the above.
2633 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
2635 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
2637 * fports.c (scm_open_file): don't return #f, throw error.
2639 * ioext.c (fileno): renamed from %fileno.
2640 (soft-fileno): deleted.
2642 * ports.c (scm_port_revealed): don't need to check for -1 from
2644 (scm_set_port_revealed_x): return unspecified, not #f.
2646 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
2648 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
2650 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
2652 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
2654 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2656 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
2657 This is necessary on Ultrix, and doesn't hurt portability.
2659 * Makefile.in (dist-dir): New target, implementing a new dist system.
2660 (installed_h_files): Put in alphabetical order.
2661 Remove duplicate entries for markers.h and unif.h.
2662 (c_files): Remove duplicate entries for markers.c.
2663 (ancillary): Renamed from anillery; all uses changed. Remove
2664 PLUGIN; it's a directory, and needs special treatment in dist-dir.
2665 Remove all the ../doc/* files; doc/Makefile.in handles that.
2667 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
2669 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
2670 every if must have an else, or else the whole command has a
2671 non-zero exit code whenever the if's condition is false.
2673 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
2675 * posix.c: include string.h.
2677 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2679 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
2682 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
2683 Remove leading % from scheme names.
2684 Do not return error values, call SCM_SYSERROR or similar.
2686 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
2688 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
2690 * struct.c (scm_init_struct): new file.
2692 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
2694 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
2695 (scm_list_head): added list-head for rapidly chopping argument
2696 lists off of longer lists (and similar).

2700 * objprop.c (scm_object_property): assq the cdr of the whash
2701 handle for obj, not the handle itself.
2703 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
2705 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
2706 weak hash tables last of all marking to avoid an obscure gc bug.
2707 WARNING: circular lists stored in a weak hash table will hose us.
2709 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
2711 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
2712 new functions similar to scm_substring_move_left_x and
2713 scm_substring_move_right_x.
2715 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
2717 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
2720 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
2722 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
2724 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
2726 * strports.c (scm_strprint_obj): convenience function. C for
2727 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
2729 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
2730 removed to a separate library
2732 * init.c (scm_boot_guile): copied from guile-tcl.c.
2733 Initialization specific to tcl interpreters removed.
2735 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
2737 * ports.c (scm_ports_prehistory): size malloced here doesn't
2738 matter so long as it is non-0 (got rid of "* 4").
2740 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
2742 * gscm.h: gscm_mkarray eliminated (presumably was not being used
2743 since its definition was bogus).
2745 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
2747 * mallocs.[ch]: back again (for rx at least).
2749 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
2751 * ports.c: removed functions relating to the mapping between ports
2752 and descriptors. (That stuff is unix-specific and should be collected
2753 in a separate library).
2755 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
2756 (Tom Mckay@avanticorp.com)
2758 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
2760 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
2761 handled correctly (SCM_FREEP was applied to them) -- test for
2762 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
2763 being overwritten with #f. (brown@grettir.bibliotech.com)
2765 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>

2787 * gscm.c (gscm_run_scm): got rid of objprop.
2789 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
2791 * genio.c (scm_getc):
2792 NOTE: fgetc may not be interruptable.
2794 * procprop.c (scm_stand_in_scm_proc):
2795 NOTE: don't use a alist here.
2796 (scm_set_procedure_properties_x): fix type checking throughout this file.
2798 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
2800 * ports.c (scm_remove_from_port_table): adjust scm_mallocated

2806 * vports.c (scm_make_soft_port): allocate a port table entry
2807 (possibly triggering gc) before setting the tag of the corresponding
2810 * pairs.c (scm_delq_x): never throw an error.
2812 * vectors.c (scm_make_vector): made the default vector fill argument
2813 into '() (much more useful than the previous value, "#unspecified")
2815 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
2817 * ports.c (scm_add_to_port_table): Added fields
2818 to port table entries: file_name, line_num, col.
2819 Update these in open_file, gen_getc and gen_ungetc.
2820 Added procedures to access those fields.
2822 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
2824 * procs.c (scm_make_subr_opt): new entry point for making
2827 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
2829 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
2831 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
2833 * numbers.c (scm_exact_p): This function no longer
2834 implements "integer?".
2836 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
2838 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
2839 (scm_gc_stats): return an assoc of useful data. Replaces "room"
2840 and the stats reporting formerlly built into repl.
2842 * repl.[ch]: removed.
2843 GC statistics keeping moved to gc.c.
2844 Other statistics keeping can be done from Scheme.
2845 REPLS are now written in Scheme.
2847 Wed Feb 21 10:28:53 1996 Tom Lord <lord@beehive>
2849 * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky

2852 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
2854 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
2856 * feature.c (scm_compiled_library_path): moved here from repl.c.
2857 This file is for stuff relating specifically to Scheme libraries
2860 * eval.c (scm_m_define): don't give warning about redefinition, don't
2863 NOTE: this should throw a resumable exception with parameters --
2864 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
2866 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
2868 * error.c: scm_warn eliminated.

2877 Tue Feb 20 00:19:10 1996 Tom Lord <lord@beehive>
2879 * throw.c (scm_ithrow): guard against the bad-throw hook changing
2880 between the call to procedurep and use.
2882 * error.c (scm_everr):
2884 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
2887 * strports.c: don't reveal the port's string to the caller
2888 because it changes size.
2890 (stputc stwrite): check/change the strings length with interrupts
2893 * objprop.c (scm_set_object_property_x &c): use the generic
2894 hashing functions and be threadsafe.

2897 (per suggestion jaffer@gnu.ai.mit.edu).
2899 * mbstrings.c (scm_multi_byte_string): guard against argument list
2902 * strings.c (scm_make_string): loop cleanup
2904 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer

2956 set the multi_byte flag correctly in symbols. This is wrong.
2957 intern_obbary_soft and msymbolize should take an extra parameter.
