1 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
6 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
8 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
9 source files that are not always included in libguile but should
10 have their dependencies calculated by automake. This variable is
11 recognized by automake, no further magic is needed.
12 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
13 to deal exclusively with *.lo files, as it seems. The *.o files
14 are built automatically when the corresponding *.lo file gets
17 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
19 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
22 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
24 * unif.c (scm_array_set_x): minor change to argument error checking.
26 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
28 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
29 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
30 They should only be included in the library at configure.in's
32 (libguile_la_LDADD): Include the appropriate .lo files here.
33 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
34 so we know when to build them (and their .lo bretheren).
35 * configure.in (LIBLOBJS): New substituted variable. We let
36 configure decide which .o files to include in LIBOBJS, and then
37 put the corresponding list of .lo files in LIBLOBJS. The latter
38 is what we pass to libtool.
39 * Makefile.in, configure: regenerated.
41 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
43 * symbols.c (scm_sysintern0): New function. Contains the core of
44 old scm_sysintern but doesn't take a second value argument.
45 (scm_sysintern): Now uses scm_sysintern0.
46 (scm_sysintern_no_module_lookup): Renamed to
47 scm_sysintern0_no_module_lookup and doesn't take a second value
50 * symbols.h (scm_sysintern0: Added declaration.
52 * options.c (scm_init_opts): Use scm_sysintern0 instead of
53 scm_sysintern when interning option keys. Otherwise we risk
54 destroying the values of already interned variables.
56 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
57 scheme-level boolean (use SCM_NFALSEP).
59 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
61 (scm_backtrace): New function. (C version of old function from
62 boot-9.scm) Motivation: Make it possible to display backtraces
63 without depending on boot-9.scm. (I'm uncertain if this
64 motivation is good enough...)
66 * root.h (scm_root_state): Add member the_last_stack_var.
67 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
69 * root.c (mark_root): Mark scm_the_last_stack_var.
71 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
74 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
76 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
77 1. mark_lazy_catch didn't mark the smob.
78 2. Both functions above have standard variants:
79 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
80 free_lazy_catch --> scm_free0.
82 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
84 * throw.c (scm_internal_lazy_catch): New function.
85 (scm_lazy_catch): Rewritten to use it.
86 (scm_ithrow): Handle the new lazy catch representation.
87 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
88 that doesn't have a jmpbuf is a lazy catch clause.
89 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
90 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
91 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
93 (scm_init_throw): Register the new lazy-catch smob type.
94 * throw.h (scm_internal_lazy_catch): decl for new function.
96 * throw.c (scm_internal_catch): Doc fixes.
98 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
99 configure.in. Including this might cause problems if applications
100 that link against libguile include their own copies of alloca, but
101 if they're using autoconf, they should be adding libguile to LIBS
102 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
103 the copy in libguile, and things will be okay. (I think.)
105 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
107 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
109 strop.h: move prototypes too.
111 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
113 * posix.c (scm_init_posix): don't intern EINTR since it's now done
116 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
117 etc. I deleted them from filesys.c long ago, but didn't
118 notice they were here too (although ineffective since
119 sys/stat.h wasn't included).
121 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
123 * eval.c: Don't define alloca in GCC case. gcc will automatically
124 use __builtin_alloca if appropriate.
126 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
128 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
129 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
130 that values of automatic variables are preserved. See comments
131 for safe_setjmp for details.
133 Change from Thomas Morgan:
134 * variable.c: Include eq.h.
135 (var_equal): New function.
136 (variable_smob): Use var_equal as the discriminator for variables.
138 * throw.c (s_throw): Remove extraneous declaration.
140 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
141 * eval.c: Add necessary CPP cruft to support that.
142 * configure, Makefile.in, scmconfig.h.in: regenerated.
144 Change from Thomas Morgan:
145 * procprop.c (scm_procedure_properties): Convert the Scheme
146 boolean returned by scm_procedure_p into a C boolean before using
147 it as a condition for SCM_ASSERT.
148 (scm_procedure_property): Likewise.
150 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
151 indications of Unixness.
154 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
156 * * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
158 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
160 * read.c (scm_lreadr): use scm_misc_error to improve one of the
161 "unknown # object" error messages.
163 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
164 (scm_i_index) and declare it static. Add a 'direction' argument
165 to indicate what way the search should go.
166 (scm_i_index): throw out-of-range error instead of wrong-type-arg
168 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
169 strop.h: remove scm_i_index, scm_i_rindex prototypes.
171 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
173 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
175 * * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
176 to avoid clash with various scsh forks.
178 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
180 The following two changes (ramap.c, throw.c) are motivated by the
181 apparent unportability of forward declarations of static arrays of
182 the form `static foo bar[];'.
184 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
185 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
187 * throw.c (scm_throw): Moved above scm_ithrow.
189 * options.h: Removed the extern declarations of scm_yes_sym and
190 scm_no_sym since these are static.
192 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
194 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
196 * Makefile.am: remove AWK=@AWK@.
197 Add a rule for generating errnos.list.
198 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
200 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
201 don't extract errnos, just set a variable (avoids the
202 need to recompile error.c just because configure is run.)
204 * unif.h: update prototypes.
205 * unif.c (scm_uniform_array_read,write): change the offset and
206 length arguments to start and end, for consistency.
208 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
210 * ioext.h: update prototypes.
211 * * ioext.c (scm_read_delimited_x): replaces scm_read_line and
212 scm_read_line_x, it's a more general procedure using an
213 interface from scsh. read-line and read-line! are now defined
215 * Note that the new read-line trims the terminator
216 by default, previously it was appended to the returned string. An
217 optional argument specifies how to process the terminator (scsh
218 compatible). For the old behaviour: (read-line port 'concat).
219 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
220 returns a pair, but is converted to multiple values if the scsh
223 socket.h: update prototypes.
224 * socket.c (scm_recvfrom): for consistency with other procedures,
225 take start and end as separate optional arguments.
226 * (scm_recv, scm_recvfrom): don't allow the second argument
227 to be a size, only a buffer. Change the scheme names to
228 recv! and recvfrom!. Don't return the buffer.
230 * ioext.h, posix.h: move prototypes too.
231 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
232 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
233 "read.h" and "unif.h".
234 * ioext.c: include "chars.h"
236 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
238 * dynl.c: The dynamic linking and module registration functions
239 are now defined even when dynamic linking is not available for the
240 host system. Some of their functionality can be done without
241 dynamic linking; when it's really needed, they throw errors.
243 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
245 * configure.in: Only define DYNAMIC_LINKING when one of the system
246 dependent functions is detected.
247 * dynl.c (scm_dynamic_func): New function to get the address of a
248 function in a dynamic object.
249 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
250 produced by scm_dynamic_func as the thing to call.
252 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
254 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
255 (scm_register_module_xxx, scm_registered_modules,
256 scm_clear_registered_modules): New functions.
258 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
260 * symbols.c (scm_sysintern): Renamed to
261 scm_sysintern_no_module_lookup.
262 (scm_sysintern): New function to take the place of the old
263 scm_sysintern. It uses the current toplevel lookup closure to give
264 the symbol its value. This is a temporary hack to put packages
265 like gtcltk into their own module.
266 (scm_can_use_top_level_lookup_closure_var): New variable to tell
267 us whether `scm_top_level_lookup_closure_var' has been initialized
269 * eval.c (scm_init_eval): Set it.
271 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
273 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
274 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
276 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
278 * (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
279 scm_sys_dup): deleted: FD capability will be added to other
281 * Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
282 scm_fd_free, fd_smob, scm_intern_fd.
283 * (scm_open): renamed from scm_sys_open. Return a port instead of
284 an FD object. Make the mode argument optional.
285 * (scm_sys_create): deleted, it's just a special case of open.
286 (scm_init_filesys): move interning of constants O_CREAT etc.,
287 here (were previously using SCM_CONST_LONG macro).
288 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
290 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
291 include "fports.h" and <stdio.h>
292 (scm_stat, scm_select): don't support FD objects.
294 * error.h: adjust scm_syserror_msg prototype.
295 * error.c (scm_syserror_msg): take an extra argument for errno.
296 Using the global value didn't always work, since it could be
297 reset by procedure calls in the message or args arguments.
299 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
300 I don't understand why the check was there (and what about the
303 * strop.c (scm_string_copy): allow shared substrings to be copied.
305 * unif.h: corresponding change to prototypes.
306 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
307 recognize two new optional arguments: offset and length. Allow
308 the port argument to be an integer (file descriptor, for scsh).
309 Include <unistd.h> for "read" prototype.
311 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
313 * socket.c: don't include filesys.h.
315 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
317 * Makefile.am: add AWK=@AWK@ (?)
319 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
321 Add a rule to generate errnos.c from errnos.
322 * error.c (scm_init_error): include errnos.c.
323 * errnos_cnvt.awk: new file, converts the list of errno codes to
325 * errnos_get.c: new file.
326 * errnos.default: new file, contains errnos to try if they can't
327 be extracted from errno.h.
328 * configure.in: if using GCC, try and extract errno codes from
332 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
334 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
335 * Makefile.am: Made libguile into a libtool library.
336 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
337 Set libtool_libs to indicate that libguile is a libtool library.
338 See guile/ChangeLog for details.
339 * .cvsignore: ignore "*.lo", the libtool library objects.
341 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
343 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
344 use htons in getservbyport argument.
346 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
348 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
349 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
352 * objprop.c (scm_object_property): No need to take the CDR of the
353 value returned by scm_object_properties, since Aug 20 change.
355 * configure.in: When checking for struct linger, #include
356 <sys/types.h> as well as <sys/socket.h>. I've never known
357 <sys/types.h> to cause any portability problems, and Solaris's
358 <sys/socket.h> needs it.
359 * configure: Rebuilt.
361 I think the Sun compiler has chosen a perverse way to interpret
362 ANSI declarations combined with K&R definitions. We'll
363 appease it a little bit. But when it invades France, we fight.
364 * print.c (scm_iprlist): Change 'tlr' argument to an int.
365 * print.h (scm_iprlist): Here too.
366 * numbers.c (scm_divbigdig): Change definition to match
367 declaration in numbers.h.
368 * unif.c (scm_makflo): Change definition to match declaration in
371 * init.c (scm_boot_guile): Don't return the value of
372 scm_boot_guile_1. This function doesn't return a value;
373 scm_boot_guile_1 doesn't return a value (or return at all).
375 * eval.c (unmemocopy): Add a semicolon to appease the Sun
378 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
379 compile. I have a feeling this function is a bad idea anyway ---
380 one should always test for features, not systems.
382 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
383 semicolons. Only pure luck kept this from being noticed earlier.
385 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
387 * socket.c (scm_recvfrom): Added missing semicolon.
389 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
391 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
392 the buffer and start and end positions for scsh networking
395 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
397 * configure.in: Revert previous change to this file; the problem
398 is due to transient automake weirdness.
399 * configure: Rebuilt.
401 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
402 PLUGIN/guile.libs. configure generates the latter from the former.
403 * Makefile.in: Rebuilt.
405 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
406 need this if we install scripts, like guile-snarf.
407 * configure: Rebuilt.
409 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
411 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
413 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
415 * socket.c (scm_addr_vector): fix faulty scm_listify.
417 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
419 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
420 style block comment is no longer considered an error.
422 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
424 * PLUGIN/guile.libs.in: New file.
425 * PLUGIN/guile.libs: Removed from repository.
426 * configure.in: Create PLUGIN/guile.libs from
427 PLUGIN/guile.libs.in. This is for including additonal libraries
428 needed for dynamic linking.
429 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
430 instead of PLUGIN/guile.libs.
432 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
434 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
436 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
437 occurrences of the given element from the list, not just the
438 first. This is how the Emacs Lisp functions behave, how the
439 analogous Common Lisp functions behave, and (I believe) how the
440 older Maclisp functions worked. I realize that this change may
441 break code, but it seemed better to break it before the Guile
444 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
445 Their prototypes were already present in gc.h, but they weren't
447 (scm_init_storage): Initialize scm_protects.
448 * root.c (scm_protects): New element of scm_sys_protects.
450 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
452 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
454 * libguile.h: Added #include "libguile/net_db.h".
456 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
457 30 change. That file is only meant for communication between the
458 configuration process and load.c. If code linked against libguile
459 wants to get at the paths mentioned in libpath.h, it can call
460 functions declared in load.h.
462 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
464 * libguile.h: Removed #include "libguile/fdsocket.h"
466 * net_db.c: Added #include <sys/socket.h>.
468 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
470 * filesys.c (scm_input_waiting_p): use select in preference to
471 FIONREAD, since the latter doesn't detect EOF.
472 Throw error if neither select nor FIONREAD available.
474 * socket.c (scm_connect): take a port, not a fd object.
475 (scm_fill_sockaddr): throw an error if fam is not recognised.
476 (scm_bind): use scm_fill_sockaddr.
477 (scm_listen): take a port, not a fd object.
478 (scm_accept): take and return a port. return #f in the car if
480 (scm_sock_fd_to_port): new procedure.
481 (scm_socket): use scm_sock_fd_to_port.
482 (scm_addr_vector): throw error if unrecognised address type.
483 take an extra argument with the calling procedure name.
484 (scm_getsockname): take a port. return #f if address can't be got.
485 (scm_getpeername): take a port. return #f if address can't be got.
486 (scm_recvfrom): take a port. return #f for address component if can't
488 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
489 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
491 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
493 * throw.c (scm_internal_catch): Make body funcs and handler funcs
494 use separate data pointers, to allow them to be designed
495 independently and reused.
496 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
497 Renamed from catch_body, catch_handler, and uncaught_throw; made
499 (struct scm_catch_body_data): Renamed from catch_body_data; moved
501 (scm_catch): Use the above.
502 (scm_throw): Don't bother printing a message for an uncaught
503 throw; we establish a default handler in init.
504 * throw.h (scm_internal_catch): Prototype updated.
505 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
507 (struct scm_body_thunk_data): New structure, used as data
508 argument to scm_body_thunk.
509 * init.c (struct main_func_closure): New structure, packaging up
510 the data to pass to the user's main function.
511 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
512 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
513 scm_internal_catch to establish a catch-all handler, using
514 scm_handle_by_message. This replaces the special-case code in
516 (invoke_main_func): Body function for scm_internal_catch; invoke
517 the user's main function, using the main_func_closure pointer to
518 decide what to pass it.
519 * root.c (struct cwdr_body_data): Remove handler_proc member.
520 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
521 (cwdr_handler): Removed.
523 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
525 * socket.h (SCM_P): update bind prototype.
526 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
528 (scm_socket): return a port, not a file descriptor object.
529 include "fports.h" and <unistd.h>
530 (scm_bind): take a port, not a file descriptor object.
531 take an extra argument for address args.
533 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
534 INADDR_NONE, INADDR_LOOPBACK.
536 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
538 * init.c: include net_db.h and not fdsocket.h.
539 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
541 * Makefile.am: corresponding changes.
542 * socket.h: renamed from fdsocket.h, fix names.
543 * net_db.h: renamed from socket.h, fix names.
544 * socket.c: renamed from fdsocket.c.
545 remove _sys from procedure names.
546 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
547 add "socket" to features list.
548 * net_db.c: renamed from socket.c.
549 remove _sys from procedure names.
550 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
551 add "net-db" to features list.
552 include "net_db.h". don't include <sys/socket.h> or
555 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
557 * tags.h (scm_tags): Removed comma at end of last enumerator.
559 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
561 Don't use GCC extensions to allocate space for debugging frames.
562 (Here he goes again! Why do we put up with this?!)
563 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
564 an scm_debug_info structure, not an in-line array of them. Add
565 'info' member, to say how many vect elements we've used, for eval
567 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
568 a new variable debug_info_end to mark the end of vect, instead of
569 the address of the 'info' pointer itself.
570 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
571 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
572 (SCM_APPLY): Explicitly allocate space for debug.vect.
573 * debug.c (scm_m_start_stack): Same, for vframe.vect.
574 * stacks.c: Adjusted for new debug frame structure.
575 (RELOC_INFO, RELOC_FRAME): New macros.
576 (stack_depth, read_frames): Use them, and new scm_debug_frame
577 element 'info', instead of magically knowing that eval frames have
578 an info pointer sitting after vect.
579 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
581 (scm_init_stacks): Formatting tweaks.
583 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
585 Give GCC more control flow information, so it can be sure that
586 variables aren't used uninitialized.
587 * error.h (scm_error, scm_syserror, scm_syserror_msg,
588 scm_sysmissing, scm_num_overflow, scm_out_of_range,
589 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
590 scm_misc_error): Tell GCC that these functions never return.
591 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
592 out the field type, call abort if SCM_ASSERT returns, to placate
594 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
595 scm_wta ever returns. We can't handle this case anyway, and this
596 gives the optimizer more information.
597 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
598 scm_wta ever returns.
600 In some cases, the code is fine, but GCC isn't smart enough to
601 figure that out; this usually happens when one variable is only
602 initialized and used when a particular condition holds true, and
603 we know that condition will never change within a given invocation
604 of the function. In this case, we simply initialize the variables
605 to placate the compiler, hopefully to a value which will cause a
606 crash if it is ever actually used.
607 * print.c (scm_iprin1): Initialize mw_pos.
608 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
609 * throw.c (scm_ithrow): Initialize dynpair.
610 * unif.c (scm_uniform_vector_ref): Initialize cra.
611 * struct.c (init_struct): Initialize prot.
612 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
614 * strports.c (scm_eval_0str): Don't return uninitialized garbage
615 if EXPR contains no expressions.
617 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
619 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
620 cause an infinite loop (???). So much for the algebraic
621 equivalency of variable-sized arrays and alloca...
623 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
625 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
626 a SCM boolean, not a C boolean.
628 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
630 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
631 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
632 rules for raising scm_mtrigger. Previously, unfortunate but not
633 unlikely circumstances could result in almost constant invokation
634 of the gc. Now, this situations should be less likely, but they
635 are not prevented completely.
637 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
639 * numbers.c (scm_fuck): Procedure removed; looks like old test
641 * numbers.h: Prototype removed.
643 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
645 * debug.h (scm_debug_frame): Change `vect' member from an in-line
646 array to a pointer, to match my Nov 21 change in eval.c.
648 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
650 * libguile.h: Added #include "libguile/backtrace.h", #include
653 * strings.c (scm_string scm_make_string scm_string_ref
654 scm_string_set_x scm_string_equal_p scm_string_append):
655 Bugfix according to scm patch from Aubrey Jaffer:
656 Corrected long-standing
657 (not (eqv? (integer->char 128)
658 (string-ref (make-string 1 (integer->char 128)) 0)))
659 bug found by John Kozak <jk@noontide.demon.co.uk>.
661 * strports.c, strports.h: Make scm_eval_0str return the value of
662 the last expression evaluated (previously, it returned void).
664 * strports.c, strports.h: New function: scm_read_0str. Does what
667 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
669 * simpos.c (scm_getenv): return #f if string can't be found in the
670 environment instead of throwing an exception, for compatibility
671 with numerous other systems.
673 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
675 * Makefile.am (.c.x): Use guile-snarf.
676 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
678 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
680 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
682 * backtrace.c (scm_display_error_message): Made non-static, and
683 renamed from display_error_message.
684 * backtrace.h (scm_display_error_message): Added extern decl.
685 * throw.c (uncaught_throw): Use it to display the error message.
687 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
689 * inet_aton.c: Use #if 0, not #ifdef 0.
691 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
693 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
694 to convert the returned value.
695 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
698 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
700 Add new interface to catch/throw, usable from C as well as
702 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
703 (scm_internal_catch): New function, replaces...
704 (scm_catch_apply): Deleted.
705 * throw.c (scm_catch_apply): Deleted; replaced with a more general
706 mechanism which is a bit more code, but can be used nicely from C
707 and implement the Scheme semantics as well.
708 (scm_internal_catch): This is the replacement; it's named after
709 the analogous function in Emacs.
710 (scm_catch): Reimplemented in terms of the above.
711 (struct catch_body_data, catch_body, catch_handler): New
712 functions, used by scm_catch.
713 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
714 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
715 support for new cwdr.
717 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
720 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
722 * acconfig.h: Added DYNAMIC_LINKING symbol.
723 * configure.in: Add option and checks for dynamic linking.
724 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
725 dynl.h: New files for dynamic linking support.
726 * Makefile.am (libguile_a_SOURCES):
728 (modinclude_HEADERS): Added "dynl.h".
729 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
731 * init.c (scm_boot_guile_1): Call
732 scm_init_dynamic_linking to initialize dynamic linking support.
734 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
736 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
737 (as we Schemers say). It needs to be global, so that I can tweak
738 it for the proper operation of unexec.
739 (scm_boot_guile_1_live): New variable, see above.
741 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
743 * guile-snarf.sh: Removed.
744 * PLUGIN/guile.libs: Added dependency for -lm.
745 * acinclude.m4: Renamed from aclocal.m4.
746 * PLUGIN/greet: Removed.
747 * Makefile.am, aclocal.m4: New files.
748 * configure.in: Updated for Automake.
750 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
752 * eval.c (scm_definedp): Use top_level_lookup_closure_var
753 and not top_level_lookup_thunk_var.
755 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
757 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
759 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
761 * eval.c (scm_definedp): Incompatibly changed to be a builtin
762 Scheme function, instead of syntax. Single argument is now a
765 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
767 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
768 scm_ra_divide): Properly terminate statements passed as arguments
769 to IVDEP macros. (Thanks to Bernard Urban.)
771 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
772 with non-constant sizes. (Thanks to Bernard Urban.)
774 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
776 It's an "eval closure", not an "eval thunk." A thunk is a
777 function of no arguments.
778 * root.h (struct scm_root_state): Renamed
779 top_level_lookup_closure_var from top_level_lookup_thunk_var.
780 (scm_top_level_lookup_closure_var): Renamed from
781 scm_top_level_lookup_thunk_var.
782 * root.c (mark_root): Uses changed.
783 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
784 * init.c (scm_start_stack): Uses changed.
785 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
786 Change scheme-visible name to *top-level-lookup-closure* from
787 *top-level-lookup-thunk*.
789 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
791 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
792 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
794 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
796 * gc.c (struct scm_heap_seg_data): Doc fixes.
798 * gc.c (scm_gc_sweep): Empty all segments' freelists before
799 sweeping. Then, prepend each segment's free cells to its
800 freelist, rather than wiping out the old value. (Thanks to Marius
803 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
804 scm_check_freelist, scm_debug_newcell): New functions and
805 variables, for debugging freelist problems.
806 * pairs.h (SCM_NEWCELL): New debugging version added.
807 * gc.h (scm_debug_newcell): Added extern declaration, used by
808 debugging version of SCM_NEWCELL.
810 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
812 On some systems <libc.h> conflicts with <unistd.h>, and should not
814 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
815 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
816 * configure.in: Call it.
817 * posix.c, filesys.c: Use its results to decide whether or not to
819 * configure, scmconfig.h.in: Rebuilt with autoconf and
822 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
824 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
825 pointer to the stdio stream before calling scm_setbuf0, so the
826 latter will be able to retrieve it. I'm surprised this didn't
827 segfault earlier. (Thanks to Christopher Lee.)
829 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
831 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
834 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
836 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
837 number of stack narrowing specifier pairs. The first specifier in
838 a pair controls inner border, the second the outer border. A
839 number means cut that number of frames, a procedure object means
840 cut until that object is found in operator position in a frame.
842 * root.c (cwdr): Bugfix.
844 * read.c: Recording of positions disabled by default.
846 * procs.c (scm_closure_p): New function.
848 * posix.c (scm_tmpnam): New function.
850 * load.c: Added #include "throw.h".
851 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
854 * load.c, load.h (scm_read_and_eval_x): New function.
856 * eval.c: Renamed debug option "deval" to "debug".
858 (scm_eval_x): `eval!' is no longer accessible from the scheme
859 level. Motivation: We can't allow operations which introduce
860 glocs into the scheme level. Guile's type system can't handle
861 these as data. Use `eval' or `read-and-eval!' as replacement.
863 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
864 SCM_CONSP since this is a macro!; Set vframe.prev to
865 scm_last_debug_frame instead of 0. In this way we can look
866 "above" the virtual start stack frame if we wish.
867 (scm_debug_hang): New function: Useful for debugging Guile in
868 certain tricky situations. Will probably be removed later...
870 * debug.h: Changed semantics of debug option "backtrace". This
871 option now only indicates whether we want automatic backtrace at
874 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
876 * ports.c: #include "filesys.h"
877 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
879 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
880 Motivation: This is system specific code which is related to file
881 I/O. It also may use select. Added code by Gary Houston to
882 detect presence of character in stdio buffers.
884 * libguile.h: #include "libguile/libpath.h"
886 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
887 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
888 SCM_SITE_DIR; Install libpath.h among the other include files.
890 * load.c, load.h (scm_sys_package_data_dir): New function.
892 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
894 * stacks.h: Bugfix: Don't use tail-array length field as stack
895 length field! This screwed GC.
897 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
899 * _scm.h: Added #ifndef around definition of macros min and max.
901 * __scm.h: Added hooks for threads to plugin to in ints protection
902 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
903 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
904 the main code in these macros duplicated and spread over multiple
905 files. Renamed SCM_THREADS_SWITCHING_CODE ->
906 SCM_THREAD_SWITCHING_CODE.
908 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
911 * guile-snarf.sh: New file.
912 * Makefile.in (inner_h_files): Added snarf.h
913 (ancillary, install, uninstall, distclean): Added actions for
915 (.c.x): Use guile-snarf.
916 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
917 (gen_c_files): Note that these depend on guile-snarf.
918 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
919 now in "snarf.h". Added #include "snarf.h" to get them.
920 * libguile.h: Added #include "snarf.h".
921 (Patches applied and tweaked by Jim Blandy.)
923 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
925 * socket.c: Use K&R style declaration for 'close'; the GNU coding
926 standards suggest against providing prototypes for system
927 functions. Thanks to Greg Troxel.
929 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
931 * strports.c (scm_eval_0str): New function.
932 #include "read.h", to get prototype for scm_read.
933 * Makefile.in (strports.o): Update dependencies.
934 * strports.h: New prototype.
936 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
937 scheme name from "int?" to "integer?". It seems to do the job.
938 * numbers.h: Rename prototype too.
939 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
942 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
943 scm_num_eq_p): Rename these according to R4RS conventions: call
944 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
945 to making libguile R4RS compliant without ice-9...
947 * load.c (scm_sys_search_load_path): Search for files under all
948 extensions listed in the %load-extensions variable. If FILENAME
949 is absolute, return it unchanged, without searching the load path.
950 (scm_loc_load_extensions): New variable, pointing to
951 %load-extensions' value cell.
952 (scm_init_load): Initialize it, and the value it points to.
953 (scm_primitive_load_path): Improve error reporting.
955 * load.c (scm_loc_load_hook): New variable, pointing to value cell
956 of new Scheme variable %load-hook.
957 (scm_primitive_load): Apply %load-hook to filename.
959 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
961 * configure.in: add tests for figuring out whether buffered data
962 is available in a FILE structure, which is needed by char-ready.
964 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
967 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
968 exceptions using misc_error instead of syserror. It seems a bit
969 odd to throw an exception if a string can't be found in the
970 environment, but it's consistent with open-file, stat etc.
971 (simpos.h): remove sys_ from getenv.
973 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
974 occurs, throw an error instead of returning errno. Return value
976 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
978 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
980 * filesys.c (scm_stat2scm): derive file type and permissions from
981 the stat mode and append them to the returned vector.
982 There isn't much overhead in doing this and it avoids the need to
983 work with S_IRUSR et al. in Scheme.
984 Define symbols scm_sym_regular etc.
985 (scm_init_filesys): don't intern S_IRUSR etc.
987 * load.c: change s_try_load and s_try_load_path to s_primitive_load
988 and s_primitive_load_path.
990 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
992 * error.h: don't declare error symbols. prototype for scm_misc_error.
994 * stackchk.c (scm_stack_overflow_key): defined here instead of in
997 * error.c: use SCM_SYMBOL to set up error keys.
998 scm_misc_error: new procedure.
1000 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1002 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1003 between `#!' and `!#' is ignored.
1004 (skip_scsh_block_comment): New function.
1006 * feature.c (scm_set_program_arguments): New argument, FIRST.
1007 * feature.h: Update prototype.
1008 * init.c (scm_boot_guile_1): Pass new argument to
1009 scm_set_program_arguments.
1011 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1013 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1014 (scm_boot_guile): Call scm_set_program_arguments here, later than
1015 the old initialization.
1017 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1018 initialization procedure.
1019 - Delete in, out, err arguments; there are other perfectly good
1020 ways to override these when desired.
1021 - Delete result argument; this function shouldn't ever return.
1022 - Rename init_func argument to main_func, for less confusion.
1023 - Delete boot_cmd argument; main_func is more general.
1024 -Add 'closure' argument, to help people pass data to main_func
1025 without resorting to global variables.
1026 - Abort if reentered; don't bother returning an error code.
1027 - Call scm_init_standard_ports to set up the default/current
1028 standard ports; no need to pass them to scm_start_stack.
1029 - Remove code to evaluate the boot_cmd, and start the repl; let
1030 the user do something like that in main_func if they want.
1031 - Remove code to package up a return value; main_func can do any
1033 - Call exit (0), instead of returning.
1034 (scm_start_stack): Don't initialize the I/O ports here; that's
1035 weird. Delete in, out, err arguments. Move guts to
1036 scm_init_standard_ports, scm_stdio_to_port.
1037 (scm_init_standard_ports): New function, to set up current and
1038 default standard ports.
1039 (scm_start_stack, scm_restart_stack): Make these static.
1040 * init.h (scm_boot_guile): Adjust declaration.
1041 (scm_start_stack, scm_restart_stack): Remove externally
1042 visible declarations for these.
1043 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1045 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1046 written out several times in scm_start_stack.
1047 * fports.h: New declaration for the above.
1049 * feature.c (scm_set_program_arguments): New function.
1050 * feature.h: New declaration for the above.
1052 * ports.c: Formatting tweak.
1054 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1056 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1057 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1058 for obtaining the address of a car or cdr field. Motivation:
1059 &SCM_CXR make assumptions about the internal structure of the
1062 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1063 Motivation: see SCM_CXRLOC.
1065 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1066 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1067 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1068 Motivation: Safer use. Some other macros are defined in terms of
1069 these operations. If these are defined using the SCM_SETCXR
1070 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1071 to inefficiency and an <e1> with side-effects could potentially
1072 break. Also, these particular operations are heavily utilized in
1073 the garbage collector. In unoptimized code there will be a
1076 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1077 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
1078 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
1079 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
1080 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
1081 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1082 vports.c: Cleaned up use of pairs: Don't make any special
1083 assumptions about the internal structure of selectors and
1084 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1085 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1086 (Among other things, this change makes it easier to build Guile
1087 with certain compilers which have problems with casted lvalues.)
1089 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1091 * stacks.c: Improve selection of relevant stack frames when making
1092 a stack object. Introduce one level of indirection in the stack
1093 object to make it possible to "narrow" to a certain region of the
1094 stack. This facilitates making use of more clever algorithms (not
1095 implemented) for selecting relevant frames and gives a cleaner
1096 design since selection of frames can be done independently of
1097 extraction of frames from the real stack.
1098 (scm_stack_id): Also take #t as argument which means look at
1101 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1102 Turn n_tail into an integer directly representing current number
1103 of frames in stack. Add field tail.
1105 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1107 * debug.c (scm_make_memoized): Made it available at scheme level.
1108 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1109 SCM_NIMP before applying heavier predicates in argument checking.
1110 (scm_local_eval): Also take memoized object as argument.
1112 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1113 aren't created with zero length, but should such a strange
1114 creature suddenly turn up...
1116 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1118 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1119 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1121 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1123 * variable.c (scm_make_variable): Make the name hint optional, as
1125 (anonymous_variable_sym): Renamed from variable_sym. All uses
1128 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1129 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1130 of scm_primitive_load_path was also changed to
1131 "primitive-load-path", from "%try-load-path". Callers changed.
1132 We'd like to respect the convention that a function named
1133 "try-mumble" should behave just like the function called "mumble",
1134 but return #f instead of signalling some error.
1135 * load.h: Rename prototypes.
1137 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1139 * print.c (make_print_state, grow_print_state), print.h: Modified
1140 the print state representation: Don't use a tail array for
1141 recording of circular references. Resizing of the print state
1142 structure invalidates the print state pointer. To avoid passing
1143 around an indirect print state reference to all printing
1144 functions, we instead let the print state reference a resizable
1147 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1149 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1150 Don't crash when passed an improper list terminated by a
1151 non-immediate value.
1153 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1155 Allocate data for structures on an eight-byte boundary, as
1156 required by the tagging system.
1157 * struct.c (alloc_struct): New function.
1158 (scm_make_struct, scm_make_vtable_vtable): Call it.
1159 * struct.h (scm_struct_n_extra_words): Bump to 3.
1160 (scm_struct_i_ptr): New "field".
1161 * gc.c (scm_gc_sweep): When we need to free the data, use the
1162 information stored by alloc_struct to find the beginning of the
1163 block allocated to the structure, so we can free it.
1165 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1167 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1170 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1171 (scm_debug_info): New member: id.
1173 * stacks.c: Stacks are now represented as structs; Stacks have an
1174 id given to them by `start-stack'.
1175 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1177 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1178 Changed stack representation.
1180 * debug.c (scm_procedure_name): Try procedure property `name' for
1181 compiled closures aswell.
1183 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
1185 * eval.c: scm_i_name moved to gsubr.c
1186 (scm_m_define): Record names of all kinds of procedure
1187 objects. (Earlier, only closures were recorded.)
1189 * procprop.h: Added declaration of scm_i_name.
1191 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1192 (scm_make_gsubr): Record names of compiled closures.
1194 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1196 * debug.c, debug.h: Removed obsolete code.
1198 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1199 stacks.c: Renamed regs --> scm_contregs.
1201 * print.c (scm_free_print_state): Cleanup print state before
1202 returning it to pool. It is better to do it here than in
1203 scm_prin1 since scm_prin1 is called often.
1205 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1206 s_set_source_property_x): Check that first argument is a pair or a
1209 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1210 scm_i_line, scm_i_column and scm_i_breakpoint global.
1212 * init.c: Added #include "backtrace.h" and #include "stacks.h".
1213 (scm_boot_guile_1): Added calls to scm_init_backtrace and
1216 * debug.h: Added debug object smob declaration and macro
1219 * configure.in: Build with backtrace.o and stacks.o if debug
1222 * Makefile.in: Added entries for new files: backtrace.c,
1223 backtrace.h, stacks.c and stacks.h.
1225 * symbols.c (scm_sym2ovcell): Fixed documentation.
1227 * _scm.h (min, max): Added.
1229 * async.c: Moved `min' macro to _scm.h.
1231 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1232 SCM_BACKTRACE_INDENT.
1234 * eval.c: Added new debug options `maxdepth' and `indent'.
1236 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
1238 * print.h: Added selector SCM_PRINT_STATE.
1240 * print.c: New functions: scm_make_print_state,
1241 scm_free_print_state.
1243 * print.h: Added declarations for scm_make_print_state,
1244 scm_free_print_state.
1246 * debug.c (scm_m_start_stack): New acro.
1248 * debug.h: Small cleanup.
1250 * init.c (scm_boot_guile_1): Moved scm_init_debug below

1275 declare functions with prototypes. (Patch thanks to Marius
1278 More prototype-related changes from Marius Vollmer:
1279 * gdb_interface.h: Wrapped header file in #ifdef/#endif
1280 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
1281 * ports.h (ptobfuns): Added prototypes. This means some casting in
1283 * fports.c: Added casts for initializations, since the functions
1284 are defined to take FILE * as their stream argument, not SCM.
1285 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
1286 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
1287 to `char *str_data' to conform to prototype.
1289 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1291 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
1293 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
1295 * stime.c, stime.h: use SCM_P method.
1297 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1299 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
1300 be given at least two arguments. Insist that lst's last element
1301 be a list, but don't make any requirements of its predecessors.
1303 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1305 * eval.c (scm_nconc2last): Revert last change; there seems to be
1306 other stuff going on here.
1308 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1310 * eval.c (scm_nconc2last): Make sure that each element of lst
1311 (which is a list of argument lists, except for the tail) is a
1312 proper list, i.e., finite and terminated by '().
1314 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1316 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
1319 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
1320 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
1323 * vectors.c (scm_make_vector): Fill vectors with the undefined
1324 value, to help make Guile Scheme code more portable to other
1327 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
1328 * symbols.h, tags.h: Doc fixes.
1330 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
1332 * async.c (scm_take_signal): Doc fixes.
1334 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
1336 * numbers.c (scm_divbigint): When the remainder is zero, we don't
1337 want to subtract it from the modulus; we just want to leave it
1340 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
1342 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
1345 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
1347 * throw.c (scm_catch_apply): Finished implementation of
1350 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
1352 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
1354 (scm_init_filesys): set "i/o-extensions" feature.
1357 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
1359 * Makefile.in (root.o): Correct dependencies.
1361 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
1363 * Makefile.in: Added dependency entry for root.o.
1365 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
1366 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
1368 * init.c (scm_start_stack): Set initial root continuation number
1371 * procs.c: New function: scm_thunk_p.
1373 * procs.h: Added declarations of scm_thunk_p.
1375 * root.c: Renamed `call-with-new-root' -->
1376 `call-with-dynamic-root'.
1377 (cwdr): Removed allocation of new root state. This should be done
1378 separately by use of scm_make_root.
1379 (scm_apply_with_dynamic_root): New function: Does what it
1380 sounds like. Needed when spawning threads.
1382 * root.h: Added member last_debug_frame to root state.
1383 Added #include "libguile/debug.h"
1385 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
1386 arguments. The motivation is that code in root.c needs catch
1387 functionality, and we want to avoid code duplication.
1388 New functions: scm_catch, scm_lazy_catch. These are wrappers for
1389 scm_catch_apply. scm_lazy_catch is intended to introduce catch
1390 handlers that run without popping the stack into the dynwind
1393 * throw.h: Added prototypes for scm_catch_apply and
1396 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1398 * root.h (scm_root, scm_set_root): Decouple thread support details
1399 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
1400 SCM_SET_THREAD_LOCAL_DATA.
1402 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
1403 and tortoise scanning loop.
1405 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
1407 * Makefile.in: Rebuild dependencies.
1409 * libguile.h: #include "libguile/print.h" before "smob.h", since
1410 the latter uses the print_state structure.
1412 * throw.c (scm_ithrow): Use the correct variable when checking to
1413 see if a given element of scm_dynwinds is a valid catch.
1415 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
1416 structure, abort; don't just silently ignore the garbage.
1418 * _scm.h: #include "print.h" here, since it seems to be used just
1420 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
1421 strports.c, unif.h: Don't #include "print.h".
1423 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1425 * feature.h (scm_loc_features): Removed external declaration.
1426 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
1428 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1430 * feature.c (scm_init_feature): Added threads feature (needs to be
1431 initialized here, since features doesn't exist when
1432 scm_init_threads is called).
1434 * libguile.h: Added #include "libguile/../threads/threads.h".
1435 (This is a kludge to get thread support working. This should be
1438 * configure.in, acconfig.h: Added flags for thread support.
1440 * scmsigs.c: Define `signal' to be `pthread_signal' if using
1443 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
1444 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
1447 * _scm.h: Added conditional #include "threads.h"
1449 * __scm.h (SCM_ASYNC_TICK): Added call to macro
1450 SCM_THREADS_SWITCHING_CODE.
1452 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
1453 allocate the basic dynamic root object.
1454 (scm_boot_guile): Added call to scm_init_root.
1456 * root.c, root.h: Added root smob.
1457 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
1458 functions: Implements dynamic roots mostly according to spec in
1459 SCM manual. Main difference is that the second argument is a
1460 throw handler rather than an error "thunk".
1462 * root.h: Added declaration of scm_init_root.
1464 * root.c: Added #include "genio.h", #include "smob.h", #include
1465 "pairs.h", #include "throw.h", #include "dynwind.h", #include
1467 (scm_init_root): Added #include "root.x".
1469 * throw.c: Added #include "stackchk.h"
1470 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
1471 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
1472 can be used in scm_call_with_new_root; Added reenabling of stack
1473 checking when catching a throw.
1475 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
1477 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
1479 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
1480 element is not found, as per R4RS.
1482 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1484 * list.c: Doc fixes throughout.
1486 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1488 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
1489 declare the char * to be const. Avoids a warning in rgx.c.
1491 * ports.h: spelling fix.
1493 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
1496 * load.c (scm_sys_try_load_path): throw an error if file not found
1497 (like it says it in NEWS).
1499 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1501 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
1502 PROPS slot to '(), not #f; it's an empty alist.
1504 * throw.h, throw.c: Use SCM_P instead of #if hair.
1506 Remove special support for uncaught throws; see throw.c for
1508 * throw.c (uncaught_throw): New function.
1509 (scm_ithrow): Call uncaught_throw if we don't find a throw
1510 target; don't mess with scm_bad_throw_vcell.
1511 (scm_bad_throw_vcell): Variable deleted.
1512 (scm_init_throw): Don't initialize it.
1514 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
1517 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1519 * numbers.c (scm_istr2int): If the number is short (as most
1520 numbers are), just call scm_small_istr2int to deal with it.
1521 (scm_small_istr2int): New function, created by un-#ifdefing the
1522 non-bignum version of scm_istr2int and renaming it.
1524 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
1526 * load.c (scm_sys_try_load): don't check whether value returned
1527 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
1528 Change the Scheme name from %try-load to primitive-load.
1530 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
1531 Can avoid passing a message, allowing it to be derived in the
1532 error handler (e.g., if we want to throw to the key both from
1535 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
1537 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
1538 references now have a new appearance which is more compact and
1539 also gives a clue about what the target of the reference is.
1540 By setting parameters in the print state, more fancy printing can
1541 be achieved. This is used by the (not yet commited) backtrace
1544 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
1546 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
1549 * print.c: Added #include "struct.h". Removed function
1552 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
1553 scm_iprin1. Removed prototype for scm_prlist.
1555 * arbiters.c (prinarb),
1556 async.c (print_async),
1557 debug.c (prindebugobj, prinmemoized),
1558 eval.c (prinprom, prinmacro),
1559 filesys.c (scm_fd_print, scm_dir_print),
1561 mallocs.c (prinmalloc),
1562 numbers.c, numbers.h (scm_floprint, scm_bigprint),
1563 smob.h (scm_smobfuns),
1564 srcprop.c (prinsrcprops),
1566 unif.c, unif.h (scm_raprin1, rapr1),
1567 variable.c (prin_var): Changed argument `int writing' to
1568 `scm_print_state *pstate'.
1570 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
1571 that it will be called before scm_init_print.
1573 * print.c (scm_prin1): Print states are now allocated when calling
1574 scm_prin1 and then passed around to all printing functions as an
1575 argument. A cache `print_state_pool' enables reuse of print
1577 (scm_make_print_state): New function.
1578 (scm_iprin1): Adaption to print states.
1579 (scm_iprlist): An initial "hare and tortoise" scan brings down
1580 time complexity to O (depth * N). (Better time complexity will be
1581 achieved when the printing code is completely rewritten.)
1583 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1585 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
1586 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
1587 it gets done whether or not the cache variable has a value.
1589 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
1591 Distinguish #f and ().
1592 * __scm.h: #undef SICP.
1593 * pairs.h (SCM_EOL): Delete this definition, equating it with
1595 * tags.h (SCM_EOL): Give it a new definition here; I think I found
1596 the value it used to have. Doc fixes, too.
1598 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
1600 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
1601 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
1602 Lord's implementation of structs, allowing for tail arrays as
1603 described in the manual. Also fixed some bugs. (Both the interface
1604 and the implementation should be improved.)
1606 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
1608 * print.c, print.h: Closures now print like #<procedure foo (x)>.
1609 People who whish to see the source can do `(print-enable 'source)'.
1610 Removed #ifdef DEBUG_EXTENSIONS.
1612 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1614 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
1615 integer (assuming for now accepting an integer is a good thing).
1617 * error.c, fports.c: replace use of %S in lgh_error args with %s.
1618 %S will be used instead for write'ing arguments.
1620 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
1621 asserts. fix a few other asserts.
1622 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
1623 scm_uniform_vector_ref, scm_array_set_x,
1624 scm_dimensions_to_unform_array): change args in
1625 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
1626 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
1627 scm_substring_fill_x): likewise.
1628 gsubr.c (scm_gsubr_apply): likewise.
1629 eval.c (SCM_APPLY): likewise.
1631 * eval.c (4 places): replace scm_everr with lgh_error or
1634 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
1635 scm_memory_error): new procedures.
1636 scm_everr: deleted. can use scm_wta, dropping first two args.
1637 scm_error: convert NULL subr to SCM_BOOL_F.
1639 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
1642 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
1645 * error.c, error.h: new error keys: scm_arg_type_key,
1646 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
1648 scm_wta: reimplement using lgh_error instead of scm_everr.
1650 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
1652 * gdbint.c: scm_lread now has one more argument.
1654 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
1655 scm_port_\1; Added mutator scm_set_port_filename_x (used when
1656 loading source from non-file ports, which, e. g., happens when
1657 using the Emacs interface).
1659 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
1662 * read.c: Added code for recording of positions of source code
1663 expressions; New functions: recsexpr, scm_lreadrecparen;
1664 _scm_make_srcprops --> scm_make_srcprops
1665 (scm_flush_ws): Removed updating of positions counters. This work
1666 is already done by scm_gen_getc
1668 * read.h: Added prototype for scm_lreadrecparen
1670 * print.c: Added #include "alist.h"
1672 * eval.c: Added #include "hash.h"
1674 * eq.c: Added #include "ramap.h"
1676 * options.c: Documentation fixes.
1678 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
1679 (scm_init_srcprop): Adjusted size of initial source-whash. Name
1680 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
1681 --> scm_make_srcprops
1683 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
1684 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
1685 function calls in the definition of the whash access macros.
1687 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
1689 * init.c (scm_boot_guile): Add level of indirection to
1690 scm_boot_guile_1() to ensure that stack base pointer is properly
1691 initialized. There was no guarantee that variable i was the
1692 highest/lowest variable on stack (i.e. the call frame of
1693 scm_boot_guile was not completely protected from gc).
1695 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
1697 * ports.h (scm_port_table): put back file_name, it will be used to
1698 support debugging. Undo related changes in fports.c, ioext.c,
1701 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1703 * ports.h (scm_port_table): remove file_name member for now, it seems
1705 * fports.c (scm_open_file): don't set file_name in PTAB.
1706 (prinfport): don't use file_name in PTAB.
1707 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
1708 * ports.c (scm_add_to_port_table): don't intialize file_name.
1709 (scm_port_file_name): remove for now.
1710 * gc.c (scm_gc_mark): don't mark PTAB file_name.
1712 * fports.h (scm_mkfile): prototype deleted.
1713 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
1715 * debug.c, unif.c: use scm_out_of_range instead of
1716 wta for range errors (ASSERT still needs work).
1718 * error.c, error.h (scm_out_of_range): new procedure.
1720 * error.c, error.h (scm_out_of_range_key): new key.
1722 * posix.c (scm_sync): #else was missing.
1724 * error.c, error.h: append _key to names scm_num_overflow and
1727 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
1728 of consing an empty list.
1729 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
1730 of macros, saves code and string space.
1731 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
1732 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
1733 lower case. Rename scm_syserror_m to scm_syserror_msg.
1734 error.h: prototypes for new procedures.
1736 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
1738 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
1740 * error.c, error.h: setup scm_num_overflow key.
1742 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
1743 Remove definition of SCM_OVSCM_FLOW.
1745 * fports.c (scm_open_file): use SCM_SYSERROR_M.
1747 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
1748 explicit message and args.
1750 * error.c, error.h, __scm.h: change system_error_sym to
1753 * error.c (system_error_sym): remove leading %% from the Scheme name
1756 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
1758 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1760 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
1761 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
1762 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
1763 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
1764 renamed. (These were introduced by unsupervised name
1767 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1769 * print.c: Added code for detection of circular references during
1770 printing. (init_ref_stack, grow_ref_stack): New functions. Added
1771 a hook for printing of closures (accessible via print options).
1772 This leads to a split of calls to scm_iprin1 into two classes:
1773 elementary print operations (e. g. the code which prints a smob)
1774 still use scm_iprin1 while top level calls (like scm_display) use
1775 scm_prin1. scm_prin1 begins by clearing the data structure used
1776 to record reference information.
1778 * print.h: Added declarations of scm_prin1 and scm_prlist.
1780 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
1782 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
1784 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
1786 * error.c (err_head): scm_iprin1 --> scm_prin1
1788 * debug.c: Adjusted header comment.
1792 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1794 * strerror.c: Doc fix.
1796 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1798 * gdbint.c (gdb_read): Now possible to run during GC.
1799 (unmark_port, remark_port): New functions.
1801 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
1803 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
1804 of allocating a new string object. Also, increase size by
1805 the factor 2 instead of 1.5.
1807 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
1809 * __scm.h (SCM_P): Corrected to run under traditional C.
1811 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
1814 * async.c: Calls to scm_sysintern corrected.
1816 * async.h (scm_async_clock): Redundant declaration removed.
1818 * continuations.c (scm_dynthrow): Redundant declaration removed.
1820 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
1821 Definition typos corrected.
1823 * debug.h: Missing declarations of functions in debug.c added
1826 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
1827 Missing declarations to functions in eval.c added.
1829 * filesys.c: Possibly uninitialized variable rv.
1831 * gc.h (scm_object_addr, scm_unhash_name): Missing
1832 declarations of functions defined in gc.c added.
1834 * genio.c: Possible typos str_data -> wstr_data. ???
1836 * genio.c: Possibly unintended shadowing of local variable
1837 `int c' (gotos out of scope of inner `c'). ???
1839 * init.c: Uninitialized `SCM last' may be used.
1841 * ioext.h: (scm_sys_isatty_p): Typo.
1843 * list.h (scm_list_head): Missing prototype for function in
1846 * numbers.c (scm_two_doubles): Changed from extern to static
1847 (is used only within numbers.c).
1849 * numbers.h: Repeated declarations removed.
1851 * ports.h (scm_close_all_ports_except): Declaration for the
1852 function defined in ports.c added.
1854 * posix.h: Missing declarations added.
1856 * procs.h (scm_make_subr_opt): Missing declaration added.
1858 * socket.h (scm_sys_gethost): Missing declaration added.
1860 * socket.h: Redundant declarations removed (they are in fdsocket.h).
1862 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
1863 Missing declarations added.
1865 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
1867 * struct.c: Uninitialized variable `SCM answer' may be used.
1869 * unif.c (l2ra): Declaration prototype.
1871 * unif.c (scm_array_equal_p): Dummy definition removed (it is
1872 defined in ramap.c).
1874 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
1875 Redundant declarations removed (they are in ramap.h).
1877 * variable.h (scm_make_udvariable,
1878 scm_make_undefined_variable): Declaration corrected to
1879 correspond variable.c.
1881 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
1882 Missing declarations added.
1884 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
1886 * Makefile.in (distclean): Don't forget to delete fd.h.
1888 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1890 * fd.h.in, tags.h: Trivial cleanups.
1892 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
1893 marksweep.h just declared functions from gc.c.
1894 * gc.h, libguile.h: Don't #include "marksweep.h".
1895 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
1896 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
1897 dependencies updated.
1899 * libguile.h: Don't #include "files.h"; it's been deleted.
1901 * files.c (scm_sys_delete_file): Moved to filesys.c.
1902 File is now empty; deleted.
1904 * filesys.c: scm_sys_delete_file is now here. Remove
1905 #if's; they seem to rely on remnants of an old portability
1906 regimen. If the problems come up again, solve them properly,
1907 using autoconf. Specifically: Don't test M_SYSV, and #define
1908 remove to be unlink if it's #defined; don't use remove just
1909 because HAVE_STDC_HEADERS is #defined.
1910 * filesys.h: Add declarations for scm_sys_delete_file.
1911 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
1912 files.o, files.h, files.c, and files.x.
1913 * init.c: Don't #include "files.h", and don't call scm_init_files.
1915 Use SCM_P instead of PROTO; the latter intrudes on the user's
1917 * params.h: Deleted; definition of SCM_P moved to...
1918 * __scm.h: ... here, where it replaces PROTO macro.
1919 * libguile.h, smob.h: Don't #include "params.h".
1920 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
1921 smob.h: Fix prototypes accordingly.
1922 * Makefile.in: Update dependencies.
1923 (inner_h_files): Remove params.h.
1925 * gc.c: #include "gc.h"; every module should include its header,
1926 to let the compiler cross-check the declarations against the
1929 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
1930 simpos.h: #include "libguile/__scm.h".
1932 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
1934 * init.c: Don't forget to #include smob.h and init.h.
1935 * Makefile.in: Dependencies updated.
1937 * smob.h: Use PROTO instead of #if __STDC__.
1939 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
1941 * __scm.h: Doc fixes.
1943 * __scm.h, libguile.h: Use "quotes" in the #includes, not
1944 <angles>; this allows `make depends' to work properly.
1946 * libguile.h: #include smob.h and pairs.h before the others; they
1947 define typedefs used by other headers.
1949 C files should #include only the header files they need, not
1950 libguile.h (which #includes all the header files); the pointless
1951 recompilation was wasting my time.
1952 * Makefile.in (all .o dependency lists): Regenerated.
1953 * libguile.h: Don't try to get a definition for size_t here...
1954 * __scm.h: Do it here.
1955 * _scm.h: Since this is the internal libguile header, put things
1956 here that all (or a majority) of the libguile files will want.
1957 Don't #include <libguile.h> here; that generates dependencies on
1958 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
1959 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
1960 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and
1962 * alist.c: Get "eq.h", "list.h", "alist.h".
1963 * append.c: Get "append.h", "list.h".
1964 * arbiters.c: Get "arbiters.h", "smob.h".
1965 * async.c: Get "async.h", "smob.h", "throw.h", "eval.h".
1966 * boolean.c: Get "boolean.h".
1967 * chars.c: Get "chars.h".

2059 * stackchk.h: #include "libguile/debug.h",
2061 * print.h, read.h: #include "options.h", since everyone who uses
2062 either of these files will need that.
2064 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2065 anyone who uses this file will need them to define the smob
2066 printing functions. Also, get markers.h, since people will need
2067 to #define the mark functions.
2069 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2070 * ports.h: ... to here.
2072 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2073 don't rely on archaic C default type rules.
2075 * fports.h: #include "libguile/ports.h", since you need that in
2076 order to parse this.
2078 * genio.h: #include "libguile/print.h", because you need that to
2079 parse this; don't bother #including "ports.h", since print.h gets
2082 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2084 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2085 this; it's now a reference to an element of *scm_root.
2087 * debug.h: Don't #include "options.h"; the compiler won't be able
2088 to find that once the headers are installed; instead, #include
2089 "libguile/options.h".
2090 * gc.h: Same, with marksweep.h.
2091 * mbstrings.h: Same, with symbols.h.
2092 * scmhob.h: Same, with _scm.h.
2093 * smob.h: Same, with params.h.
2095 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2096 C files; there's no need for this, and it forces recompilations
2099 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2101 * error.c (scm_error): declare scm_error_callback.
2103 * error.h: prototype for scm_error_callback.
2105 * __scm.h: define lgh_error.
2106 (SCM_SYSERROR): redefine using lgh_error.
2108 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2110 * error.c (scm_error): new procedure.
2112 * error.h: prototype for scm_error.
2114 * Makefile.in (install): install scmconfig.h from the current
2115 directory, not $(srcdir).
2117 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2119 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2120 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2121 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

2127 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2128 vports.h, weaks.h: #include "libguile/__scm.h", not
2129 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2130 dependencies are within libguile properly.
2132 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2134 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2135 when scmconfig.h doesn't exist.
2137 * load.c (scm_sys_try_load): Correct spelling.
2139 * feature.c (scm_loc_features): Make this static.
2141 * Makefile.in (libpath.h): Omit trailing slash from path. We
2142 shouldn't require it of users, so why put it here?
2144 Move code to initialize and search %load-path from ice-9 to C
2145 code, so we can use the load-path to find the ice-9 boot code;
2146 this makes it easier to run Guile without installing it. See
2147 corresponding changes in guile/Makefile.in.
2148 * feature.c: Move stuff concerned with the load path to load.c.
2149 (scm_compiled_library_path): Deleted.
2150 Don't #include libpath.h here.
2151 * feature.h: Don't mention scm_compiled_library_path.
2152 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2153 <sys/stat.h>, and <unistd.h> (if present).
2154 (R_OK): #define if the system hasn't deigned to.
2155 (scm_loc_load_path): New variable.
2156 (scm_init_load_path, scm_sys_search_load_path,
2157 scm_sys_try_load_path): New functions.
2158 (scm_init_load): Initialize scm_loc_load_path to point to the
2159 value cell of the Scheme %load-path variable.
2160 * load.h: Add declarations for scm_sys_search_load_path,
2161 scm_sys_try_load_path.
2162 * init.c: Call scm_init_load_path.
2163 * Makefile.in (feature.o, load.o): Dependencies updated.
2165 * load.c, load.h: Rewrite using PROTO macro.
2167 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2169 * gc.c (scm_cellp): New function: C predicate to determine if an
2170 SCM value can be regarded as a pointer to a cell on the heap.
2172 * gc.h: Added declaration of scm_cellp.
2174 * gdb_interface.h: New file: The GDB interface header from the GDB
2177 * gdbint.c: New file: GDB interface.
2179 * gdbint.h: New file: GDB interface.
2181 * libguile.h: Added #include <libguile/gdbint.h>.
2183 * init.c (scm_boot_guile): Added scm_init_gdbint.
2185 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2186 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2187 found if object files and source are kept separate).
2189 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2191 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2193 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2195 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2196 TK_SRC_DIR; they're not relevant any more.
2198 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2199 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2201 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2203 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2204 search path, so we can find the <libguile/MUMBLE.h> headers.
2206 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2208 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2209 implicit in the .c.o rule.
2210 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2213 Put the library path in a header file, instead of passing it on
2214 the command line in every compilation.
2215 * Makefile.in (libpath.h): New target.
2216 (feature.o): Depend on libpath.h.
2217 (clean): Delete libpath.h.
2218 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2219 * feature.c: ... #include "libpath.h" here.
2220 * .cvsignore: Ignore libpath.h.
2222 Don't install the unwashed masses of Guile header files in the
2223 main #include path; put most of them in a subdirectory called
2224 'libguile'. This avoids naming conflicts between Guile header
2225 files and system header files (of which there were a few).
2226 * Makefile.in (pkgincludedir): Deleted.
2227 (innerincludedir): New variable; this and $(includedir) are enough.
2228 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
2229 (installed_h_files): Divide this up. Now this variable lists
2230 those header files which should go into $(includedir) (i.e. appear
2231 directly in the #include path), and ...
2232 (inner_h_files): ... this new variable says which files appear in
2233 a subdirectory, and are referred to as <libguile/mumble.h>.
2234 (h_files): List them both.
2235 (install): Create innerincludedir, not pkgincludedir. Put
2236 the installed_h_files and inner_h_files in their proper places.
2237 (uninstall): Corresponding changes.
2238 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2239 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2240 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
2241 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
2242 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
2243 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2244 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2245 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2246 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2247 vports.h, weaks.h: Find __scm.h in its new location.
2248 * __scm.h: Find scmconfig.h and tags.h in their new locations
2249 (they're both "inner" files).
2251 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
2253 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
2255 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2257 * posix.c: Doc fixes.
2259 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
2261 * socket.c: Don't include a prototype for inet_aton; just use a
2262 K&R style declaration, to avoid warnings but minimize the chance
2263 of conflicts with the system.
2265 On NextStep, <utime.h> doesn't define struct utime, unless we
2266 #define _POSIX_SOURCE before #including it.
2267 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
2268 * acconfig.h: New comment text for above CPP symbol.
2269 * configure.in: Call it.
2270 * posix.c: #define _POSIX_SOURCE if it seems necessary.
2272 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
2274 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
2275 testing for __EMX__.
2277 * posix.c: #include <libc.h>, if it exists.
2279 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
2280 don't even know if the latter exists.
2282 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
2283 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
2284 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
2286 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
2288 (scm_init_posix): Use them when initializing the Scheme constants
2291 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2293 * Makefile.in (libdir, includedir, bindir): Use the
2294 autoconf-supplied values, instead of deriving them ourselves.
2295 (pkgincludedir, datadir, pkgdatadir): New variables.
2296 (install, uninstall): Put the header files in a special
2297 subdirectory, not in the main search path.
2299 * Makefile.in (ALL_CFLAGS): Provide the proper value for
2300 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
2302 * Makefile.in (IMPLPATH): Deleted; never used.
2304 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
2305 on the Tcl/Tk source any more.
2306 (INCLUDE_CFLAGS): Remove references to the above.
2308 * Makefile.in (version.o): Corrected dependencies.
2310 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
2312 * libguile.h: #include "version.h"
2314 * init.c (scm_boot_guile): Call scm_init_version.
2315 * gscm.c (gscm_run_scm): Call scm_init_version.
2317 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
2318 GUILE_VERSION): AC_DEFINE these.
2319 (acconfig.h): #undef the above symbols.
2321 * Makefile.in (libobjs): Add version.o.
2322 (installed_h_files): Add version.h.
2323 (c_files): Add version.c.
2324 (gen_c_files): Add version.x.
2325 (version.o): New rule.
2326 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
2327 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

2336 weaks.o): Add version.h to dependency lists.
2337 (markers.o): Remove duplicate rule.
2339 * version.h: New file.
2341 * version.c: New file.
2343 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2345 * symbols.c (scm_strhash): scm_downcase is now a function, not an
2346 array; use it appropriately. Since GCC is quite happy to
2347 subscript functions, it never warned us about this; we should use
2348 -Wpointer-arith in the future. I guess we never tested
2351 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2353 * socket.c: Doc and copyright fixes.
2355 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2357 * debug.c: Fixed and improved gdb support.
2359 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2361 * socket.c: Added declaration of inet_aton to avoid compiler
2362 warning. (Hope this solution is correct.)
2364 * stime.c: Added declaration of ftime. (This is missing in
2367 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
2369 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2371 * Makefile.in (c_files): add strerror.c.
2373 * strerror.c: new file from Emacs' sysdep.c.
2374 maybe configure should also check for sys_errlist.
2376 * configure.in (AC_REPLACE_FUNCS): add strerror.
2378 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2380 * debug.c (scm_init_debug): Added initialization for
2381 scm_evaluator_traps.
2383 * debug.h, debug.c: Various name changes.
2384 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
2385 "debug-options-interface". See commentary in options.c.
2387 * options.h, options.c: Options now have documentation strings.
2388 Also added a long explanatory commentary.
2390 * eval.c, print.h, print.c, read.h, read.c: Modifications to
2393 * gscm.c, init.c, root.c, throw.c: Bug fixes:
2394 last_debug_info_frame is now updated in all cases.
2396 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
2399 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2401 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
2402 Added option STACK_CHECKING.
2404 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
2406 * Makefile.in: Added {debug,options,srcprop}.{h,c}
2408 * __scm.h: Removed symbols for debugging support.
2410 * acconfig.h: Added symbols for debugging support.
2412 * configure.in: Added user option for debugging support.
2413 --enable-debug will include the debugging code into libguile.a.
2415 * continuations.c (scm_make_cont): Enlarged the #if 0 around
2416 scm_relocate_chunk_to_heap.
2418 * debug.c: New file: low-level debugging support. It also
2419 includes support for debugging with gdb. (The extensions to gdb
2420 are written by Per Bothner at Cygnus.)
2422 * debug.h: New file: low-level debugging support.
2424 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
2425 argument pairs. Extensive modifications to the debugging
2426 evaluator. Added "SECTION:" commentaries to clarify what happens
2427 when, during double compilation. Renamed EVALIMP --> EVALIM.
2428 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
2429 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
2430 the beginning of the file. New procedure: scm_unmemocopy.
2431 Added some global state variables needed by the debugging
2432 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
2433 check_entry, check_apply, check_exit, debug_options and
2434 evaluator_traps. New acro: undefine.
2436 * eval.h: Renamed EVAL --> XEVAL.
2438 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
2439 --> scm_make_weak_key_hash_table.
2441 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
2442 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
2444 * libguile.h: Conditionally include debug.h
2446 * objprop.c (scm_object_properties, scm_set_object_properties_x):
2447 scm_object_properties shouldn't return handle. `handle' now gets
2448 initialized in scm_set_object_properties_x. scm_object_properties
2449 doesn't any longer create an entry in scm_object_whash.
2451 * options.c: New file: handling of run time options.
2453 * options.h: New file: handling of run time options.
2455 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
2457 * print.c: New procedure: scm_print_options
2459 * print.h: Defines for print options.

2476 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2478 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
2480 * libguile.h: #include "objprop.h"; I guess this was forgotten.
2482 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
2483 and should be called by the final client.
2485 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
2487 * gc.h: Use the PROTO macro when declaring functions.
2488 * gc.c: Use the PROTO macro when declaring static functions.
2489 Remove the CPP hair around function definitions.
2491 * gc.c (scm_init_storage): Initialize scm_asyncs.
2493 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
2494 preprocessor symbol; "__scm.h" is where it might get #defined.
2495 * __scm.h: Similar: #include <scmconfig.h> before testing
2498 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
2500 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
2502 * init.c (scm_boot_guile): Add init_func argument; call
2503 (*init_func) instead of calling scm_appinit; it's ucky to
2504 hard-code names for the user's procedures.
2505 * init.h (scm_boot_guile): Adjust declaration.
2507 * __scm.h (PROTO): New macro, for declaring functions with
2510 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
2511 eliminate all the __STDC__ conditionals.
2512 (scm_boot_guile): Add declaration.
2513 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
2514 Remove __STDC__ conditionals around function definitions; the
2515 declarations in init.h will provide the same information, more
2518 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
2519 complain about it in the error message; the error message is
2520 adequate without that note, and there's nothing the user can do
2523 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
2525 * Makefile.in (ancillary): Drop def.sed.
2527 * posix.c (scm_init_posix): Use numeric values, rather than
2528 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
2529 F_OK. The symbols aren't available on some systems, and I'm
2530 pretty sure their values are fixed by common widespread practice.
2531 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
2533 More functions unavailable on some systems.
2534 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
2535 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
2537 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2538 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
2539 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
2540 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
2541 stub that signals an error as the #else.
2543 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
2545 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
2547 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
2549 * unif.c: include ramap.h.
2551 * read.c (endif): case_insensative_p renamed case_insensitive_p.

2555 * ports.c: include sys/ioctl.h.
2557 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
2559 * configure.in: check for sys/ioctl.h.
2561 * ports.c: include <malloc.h> not "malloc.h".
2563 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2565 * fports.c: remove ttyname and tmpnam declarations.
2567 * posix.c: fewer ttyname declarations.
2569 * fports.c: include <string.h> not "string.h".
2571 * init.c, ioext.c: include string.h and unistd.h.
2573 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2575 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
2576 genio.c, simpos.c, vports.c: include string.h.
2578 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
2580 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
2582 (scm_addr_buffer_size): change type from scm_sizet to int.
2583 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
2584 from scm_sizet to int.
2586 * error.c: include unistd.h.
2588 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
2591 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
2593 * __scm.hd, def.sed: deleted.
2595 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
2597 Changes for NeXT, suggested by Robert Brown.
2598 * configure.in: Call AC_TYPE_MODE_T.
2599 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
2600 NeXT. Put header file list in alphabetical order.
2601 * configure, scmconfig.h.in: Regenerated.
2602 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
2604 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
2607 * acconfig.h: New file, providing documentation for the CPP
2608 symbols defined in configure.in
2609 * acconfig-1.5.h: Removed; superceded by the above.
2611 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
2613 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
2615 * fports.c (scm_open_file): don't return #f, throw error.
2617 * ioext.c (fileno): renamed from %fileno.
2618 (soft-fileno): deleted.
2620 * ports.c (scm_port_revealed): don't need to check for -1 from
2622 (scm_set_port_revealed_x): return unspecified, not #f.
2624 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
2626 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
2628 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
2630 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
2632 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2634 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
2635 This is necessary on Ultrix, and doesn't hurt portability.
2637 * Makefile.in (dist-dir): New target, implementing a new dist system.
2638 (installed_h_files): Put in alphabetical order.
2639 Remove duplicate entries for markers.h and unif.h.
2640 (c_files): Remove duplicate entries for markers.c.
2641 (ancillary): Renamed from anillery; all uses changed. Remove
2642 PLUGIN; it's a directory, and needs special treatment in dist-dir.
2643 Remove all the ../doc/* files; doc/Makefile.in handles that.
2645 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
2647 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
2648 every if must have an else, or else the whole command has a
2649 non-zero exit code whenever the if's condition is false.
2651 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
2653 * posix.c: include string.h.
2655 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2657 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
2660 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
2661 Remove leading % from scheme names.
2662 Do not return error values, call SCM_SYSERROR or similar.
2664 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
2666 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
2668 * struct.c (scm_init_struct): new file.
2670 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
2672 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
2673 (scm_list_head): added list-head for rapidly chopping argument
2674 lists off of longer lists (and similar).

2679 handle for obj, not the handle itself.
2681 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
2683 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
2684 weak hash tables last of all marking to avoid an obscure gc bug.
2685 WARNING: circular lists stored in a weak hash table will hose us.
2687 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
2689 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
2690 new functions similar to scm_substring_move_left_x and
2691 scm_substring_move_right_x.
2693 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
2695 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
2698 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
2700 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
2702 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
2704 * strports.c (scm_strprint_obj): convenience function. C for
2705 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
2707 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
2708 removed to a separate library
2710 * init.c (scm_boot_guile): copied from guile-tcl.c.
2711 Initialization specific to tcl interpreters removed.
2713 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
2715 * ports.c (scm_ports_prehistory): size malloced here doesn't
2716 matter so long as it is non-0 (got rid of "* 4").
2718 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
2720 * gscm.h: gscm_mkarray eliminated (presumably was not being used
2721 since its definition was bogus).
2723 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
2725 * mallocs.[ch]: back again (for rx at least).
2727 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
2729 * ports.c: removed functions relating to the mapping between ports
2730 and descriptors. (That stuff is unix-specific and should be collected
2731 in a separate library).
2733 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
2734 (Tom Mckay@avanticorp.com)
2736 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
2738 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
2739 handled correctly (SCM_FREEP was applied to them) -- test for
2740 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
2741 being overwritten with #f. (brown@grettir.bibliotech.com)
2743 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>

2765 * gscm.c (gscm_run_scm): got rid of objprop.
2767 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>

2773 NOTE: don't use a alist here.
2774 (scm_set_procedure_properties_x): fix type checking throughout this file.
2776 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
2778 * ports.c (scm_remove_from_port_table): adjust scm_mallocated

2784 * vports.c (scm_make_soft_port): allocate a port table entry
2785 (possibly triggering gc) before setting the tag of the corresponding
2788 * pairs.c (scm_delq_x): never throw an error.
2790 * vectors.c (scm_make_vector): made the default vector fill argument
2791 into '() (much more useful than the previous value, "#unspecified")
2793 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
2795 * ports.c (scm_add_to_port_table): Added fields
2796 to port table entries: file_name, line_num, col.
2797 Update these in open_file, gen_getc and gen_ungetc.
2798 Added procedures to access those fields.
2800 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
2802 * procs.c (scm_make_subr_opt): new entry point for making
2805 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
2807 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
2809 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
2811 * numbers.c (scm_exact_p): This function no longer
2812 implements "integer?".
2814 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
2816 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
2817 (scm_gc_stats): return an assoc of useful data. Replaces "room"
2818 and the stats reporting formerlly built into repl.
2820 * repl.[ch]: removed.
2821 GC statistics keeping moved to gc.c.
2822 Other statistics keeping can be done from Scheme.
2823 REPLS are now written in Scheme.

2830 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
2832 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
2834 * feature.c (scm_compiled_library_path): moved here from repl.c.
2835 This file is for stuff relating specifically to Scheme libraries
2838 * eval.c (scm_m_define): don't give warning about redefinition, don't
2841 NOTE: this should throw a resumable exception with parameters --
2842 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
2844 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.

2866 because it changes size.
2868 (stputc stwrite): check/change the strings length with interrupts
2871 * objprop.c (scm_set_object_property_x &c): use the generic
2872 hashing functions and be threadsafe.

2875 (per suggestion jaffer@gnu.ai.mit.edu).
2877 * mbstrings.c (scm_multi_byte_string): guard against argument list
2880 * strings.c (scm_make_string): loop cleanup

2908 initialization to fix a race condition.
2910 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

2912 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
2914 * throw.c (_scm_throw): Pass throwval on the stack, not in a global
2915 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
2917 * *.[ch]: namespace cleanup. Changed all (nearly) exported CPP
2918 and C symbols to begin with SCM_ or scm_.

2933 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
2934 set the multi_byte flag correctly in symbols. This is wrong.
2935 intern_obbary_soft and msymbolize should take an extra parameter.
2936 Also, weird multibyte symbols don't print correctly.
2937 The weird symbol syntax is also a bit bogus (emacs doesn't quite
