1 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3 * throw.c (scm_internal_lazy_catch): New function.
4 (scm_lazy_catch): Rewritten to use it.
5 (scm_ithrow): Handle the new lazy catch representation.
6 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
7 that doesn't have a jmpbuf is a lazy catch clause.
8 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
9 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
10 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
12 (scm_init_throw): Register the new lazy-catch smob type.
13 * throw.h (scm_internal_lazy_catch): decl for new function.
15 * throw.c (scm_internal_catch): Doc fixes.
17 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
18 configure.in. Including this might cause problems if applications
19 that link against libguile include their own copies of alloca, but
20 if they're using autoconf, they should be adding libguile to LIBS
21 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
22 the copy in libguile, and things will be okay. (I think.)
24 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
26 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
28 strop.h: move prototypes too.
30 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
32 * posix.c (scm_init_posix): don't intern EINTR since it's now done
35 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
36 etc. I deleted them from filesys.c long ago, but didn't
37 notice they were here too (although ineffective since
38 sys/stat.h wasn't included).
40 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
42 * eval.c: Don't define alloca in GCC case. gcc will automatically
43 use __builtin_alloca if appropriate.
45 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
47 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
48 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
49 that values of automatic variables are preserved. See comments
50 for safe_setjmp for details.
52 Change from Thomas Morgan:
53 * variable.c: Include eq.h.
54 (var_equal): New function.
55 (variable_smob): Use var_equal as the discriminator for variables.
57 * throw.c (s_throw): Remove extraneous declaration.
59 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
60 * eval.c: Add necessary CPP cruft to support that.
61 * configure, Makefile.in, scmconfig.h.in: regenerated.
63 Change from Thomas Morgan:
64 * procprop.c (scm_procedure_properties): Convert the Scheme
65 boolean returned by scm_procedure_p into a C boolean before using
66 it as a condition for SCM_ASSERT.
67 (scm_procedure_property): Likewise.
69 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
70 indications of Unixness.
73 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
75 * * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
77 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
79 * read.c (scm_lreadr): use scm_misc_error to improve one of the
80 "unknown # object" error messages.
82 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
83 (scm_i_index) and declare it static. Add a 'direction' argument
84 to indicate what way the search should go.
85 (scm_i_index): throw out-of-range error instead of wrong-type-arg
87 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
88 strop.h: remove scm_i_index, scm_i_rindex prototypes.
90 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
92 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
94 * * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
95 to avoid clash with various scsh forks.
97 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
99 The following two changes (ramap.c, throw.c) are motivated by the
100 apparent unportability of forward declarations of static arrays of
101 the form `static foo bar[];'.
103 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
104 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
106 * throw.c (scm_throw): Moved above scm_ithrow.
108 * options.h: Removed the extern declarations of scm_yes_sym and
109 scm_no_sym since these are static.
111 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
113 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
115 * Makefile.am: remove AWK=@AWK@.
116 Add a rule for generating errnos.list.
117 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
119 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
120 don't extract errnos, just set a variable (avoids the
121 need to recompile error.c just because configure is run.)
123 * unif.h: update prototypes.
124 * unif.c (scm_uniform_array_read,write): change the offset and
125 length arguments to start and end, for consistency.
127 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
129 * ioext.h: update prototypes.
130 * * ioext.c (scm_read_delimited_x): replaces scm_read_line and
131 scm_read_line_x, it's a more general procedure using an
132 interface from scsh. read-line and read-line! are now defined
134 * Note that the new read-line trims the terminator
135 by default, previously it was appended to the returned string. An
136 optional argument specifies how to process the terminator (scsh
137 compatible). For the old behaviour: (read-line port 'concat).
138 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
139 returns a pair, but is converted to multiple values if the scsh
142 socket.h: update prototypes.
143 * socket.c (scm_recvfrom): for consistency with other procedures,
144 take start and end as separate optional arguments.
145 * (scm_recv, scm_recvfrom): don't allow the second argument
146 to be a size, only a buffer. Change the scheme names to
147 recv! and recvfrom!. Don't return the buffer.
149 * ioext.h, posix.h: move prototypes too.
150 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
151 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
152 "read.h" and "unif.h".
153 * ioext.c: include "chars.h"
155 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
157 * dynl.c: The dynamic linking and module registration functions
158 are now defined even when dynamic linking is not available for the
159 host system. Some of their functionality can be done without
160 dynamic linking; when it's really needed, they throw errors.
162 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
164 * configure.in: Only define DYNAMIC_LINKING when one of the system
165 dependent functions is detected.
166 * dynl.c (scm_dynamic_func): New function to get the address of a
167 function in a dynamic object.
168 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
169 produced by scm_dynamic_func as the thing to call.
171 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
173 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
174 (scm_register_module_xxx, scm_registered_modules,
175 scm_clear_registered_modules): New functions.
177 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
179 * symbols.c (scm_sysintern): Renamed to
180 scm_sysintern_no_module_lookup.
181 (scm_sysintern): New function to take the place of the old
182 scm_sysintern. It uses the current toplevel lookup closure to give
183 the symbol its value. This is a temporary hack to put packages
184 like gtcltk into their own module.
185 (scm_can_use_top_level_lookup_closure_var): New variable to tell
186 us whether `scm_top_level_lookup_closure_var' has been initialized
188 * eval.c (scm_init_eval): Set it.
190 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
192 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
193 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
195 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
197 * (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
198 scm_sys_dup): deleted: FD capability will be added to other
200 * Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
201 scm_fd_free, fd_smob, scm_intern_fd.
202 * (scm_open): renamed from scm_sys_open. Return a port instead of
203 an FD object. Make the mode argument optional.
204 * (scm_sys_create): deleted, it's just a special case of open.
205 (scm_init_filesys): move interning of constants O_CREAT etc.,
206 here (were previously using SCM_CONST_LONG macro).
207 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
209 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
210 include "fports.h" and <stdio.h>
211 (scm_stat, scm_select): don't support FD objects.
213 * error.h: adjust scm_syserror_msg prototype.
214 * error.c (scm_syserror_msg): take an extra argument for errno.
215 Using the global value didn't always work, since it could be
216 reset by procedure calls in the message or args arguments.
218 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
219 I don't understand why the check was there (and what about the
222 * strop.c (scm_string_copy): allow shared substrings to be copied.
224 * unif.h: corresponding change to prototypes.
225 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
226 recognize two new optional arguments: offset and length. Allow
227 the port argument to be an integer (file descriptor, for scsh).
228 Include <unistd.h> for "read" prototype.
230 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
232 * socket.c: don't include filesys.h.
234 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
236 * Makefile.am: add AWK=@AWK@ (?)
238 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
240 Add a rule to generate errnos.c from errnos.
241 * error.c (scm_init_error): include errnos.c.
242 * errnos_cnvt.awk: new file, converts the list of errno codes to
244 * errnos_get.c: new file.
245 * errnos.default: new file, contains errnos to try if they can't
246 be extracted from errno.h.
247 * configure.in: if using GCC, try and extract errno codes from
251 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
253 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
254 * Makefile.am: Made libguile into a libtool library.
255 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
256 Set libtool_libs to indicate that libguile is a libtool library.
257 See guile/ChangeLog for details.
258 * .cvsignore: ignore "*.lo", the libtool library objects.
260 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
262 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
263 use htons in getservbyport argument.
265 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
267 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
268 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
271 * objprop.c (scm_object_property): No need to take the CDR of the
272 value returned by scm_object_properties, since Aug 20 change.
274 * configure.in: When checking for struct linger, #include
275 <sys/types.h> as well as <sys/socket.h>. I've never known
276 <sys/types.h> to cause any portability problems, and Solaris's
277 <sys/socket.h> needs it.
278 * configure: Rebuilt.
280 I think the Sun compiler has chosen a perverse way to interpret
281 ANSI declarations combined with K&R definitions. We'll
282 appease it a little bit. But when it invades France, we fight.
283 * print.c (scm_iprlist): Change 'tlr' argument to an int.
284 * print.h (scm_iprlist): Here too.
285 * numbers.c (scm_divbigdig): Change definition to match
286 declaration in numbers.h.
287 * unif.c (scm_makflo): Change definition to match declaration in
290 * init.c (scm_boot_guile): Don't return the value of
291 scm_boot_guile_1. This function doesn't return a value;
292 scm_boot_guile_1 doesn't return a value (or return at all).
294 * eval.c (unmemocopy): Add a semicolon to appease the Sun
297 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
298 compile. I have a feeling this function is a bad idea anyway ---
299 one should always test for features, not systems.
301 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
302 semicolons. Only pure luck kept this from being noticed earlier.
304 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
306 * socket.c (scm_recvfrom): Added missing semicolon.
308 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
310 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
311 the buffer and start and end positions for scsh networking
314 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
316 * configure.in: Revert previous change to this file; the problem
317 is due to transient automake weirdness.
318 * configure: Rebuilt.
320 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
321 PLUGIN/guile.libs. configure generates the latter from the former.
322 * Makefile.in: Rebuilt.
324 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
325 need this if we install scripts, like guile-snarf.
326 * configure: Rebuilt.
328 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
330 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
332 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
334 * socket.c (scm_addr_vector): fix faulty scm_listify.
336 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
338 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
339 style block comment is no longer considered an error.
341 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
343 * PLUGIN/guile.libs.in: New file.
344 * PLUGIN/guile.libs: Removed from repository.
345 * configure.in: Create PLUGIN/guile.libs from
346 PLUGIN/guile.libs.in. This is for including additonal libraries
347 needed for dynamic linking.
348 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
349 instead of PLUGIN/guile.libs.
351 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
353 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
355 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
356 occurrences of the given element from the list, not just the
357 first. This is how the Emacs Lisp functions behave, how the
358 analogous Common Lisp functions behave, and (I believe) how the
359 older Maclisp functions worked. I realize that this change may
360 break code, but it seemed better to break it before the Guile
363 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
364 Their prototypes were already present in gc.h, but they weren't
366 (scm_init_storage): Initialize scm_protects.
367 * root.c (scm_protects): New element of scm_sys_protects.
369 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
371 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
373 * libguile.h: Added #include "libguile/net_db.h".
375 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
376 30 change. That file is only meant for communication between the
377 configuration process and load.c. If code linked against libguile
378 wants to get at the paths mentioned in libpath.h, it can call
379 functions declared in load.h.
381 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
383 * libguile.h: Removed #include "libguile/fdsocket.h"
385 * net_db.c: Added #include <sys/socket.h>.
387 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
389 * filesys.c (scm_input_waiting_p): use select in preference to
390 FIONREAD, since the latter doesn't detect EOF.
391 Throw error if neither select nor FIONREAD available.
393 * socket.c (scm_connect): take a port, not a fd object.
394 (scm_fill_sockaddr): throw an error if fam is not recognised.
395 (scm_bind): use scm_fill_sockaddr.
396 (scm_listen): take a port, not a fd object.
397 (scm_accept): take and return a port. return #f in the car if
399 (scm_sock_fd_to_port): new procedure.
400 (scm_socket): use scm_sock_fd_to_port.
401 (scm_addr_vector): throw error if unrecognised address type.
402 take an extra argument with the calling procedure name.
403 (scm_getsockname): take a port. return #f if address can't be got.
404 (scm_getpeername): take a port. return #f if address can't be got.
405 (scm_recvfrom): take a port. return #f for address component if can't
407 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
408 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
410 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
412 * throw.c (scm_internal_catch): Make body funcs and handler funcs
413 use separate data pointers, to allow them to be designed
414 independently and reused.
415 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
416 Renamed from catch_body, catch_handler, and uncaught_throw; made
418 (struct scm_catch_body_data): Renamed from catch_body_data; moved
420 (scm_catch): Use the above.
421 (scm_throw): Don't bother printing a message for an uncaught
422 throw; we establish a default handler in init.
423 * throw.h (scm_internal_catch): Prototype updated.
424 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
426 (struct scm_body_thunk_data): New structure, used as data
427 argument to scm_body_thunk.
428 * init.c (struct main_func_closure): New structure, packaging up
429 the data to pass to the user's main function.
430 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
431 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
432 scm_internal_catch to establish a catch-all handler, using
433 scm_handle_by_message. This replaces the special-case code in
435 (invoke_main_func): Body function for scm_internal_catch; invoke
436 the user's main function, using the main_func_closure pointer to
437 decide what to pass it.
438 * root.c (struct cwdr_body_data): Remove handler_proc member.
439 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
440 (cwdr_handler): Removed.
442 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
444 * socket.h (SCM_P): update bind prototype.
445 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
447 (scm_socket): return a port, not a file descriptor object.
448 include "fports.h" and <unistd.h>
449 (scm_bind): take a port, not a file descriptor object.
450 take an extra argument for address args.
452 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
453 INADDR_NONE, INADDR_LOOPBACK.
455 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
457 * init.c: include net_db.h and not fdsocket.h.
458 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
460 * Makefile.am: corresponding changes.
461 * socket.h: renamed from fdsocket.h, fix names.
462 * net_db.h: renamed from socket.h, fix names.
463 * socket.c: renamed from fdsocket.c.
464 remove _sys from procedure names.
465 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
466 add "socket" to features list.
467 * net_db.c: renamed from socket.c.
468 remove _sys from procedure names.
469 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
470 add "net-db" to features list.
471 include "net_db.h". don't include <sys/socket.h> or
474 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
476 * tags.h (scm_tags): Removed comma at end of last enumerator.
478 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
480 Don't use GCC extensions to allocate space for debugging frames.
481 (Here he goes again! Why do we put up with this?!)
482 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
483 an scm_debug_info structure, not an in-line array of them. Add
484 'info' member, to say how many vect elements we've used, for eval
486 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
487 a new variable debug_info_end to mark the end of vect, instead of
488 the address of the 'info' pointer itself.
489 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
490 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
491 (SCM_APPLY): Explicitly allocate space for debug.vect.
492 * debug.c (scm_m_start_stack): Same, for vframe.vect.
493 * stacks.c: Adjusted for new debug frame structure.
494 (RELOC_INFO, RELOC_FRAME): New macros.
495 (stack_depth, read_frames): Use them, and new scm_debug_frame
496 element 'info', instead of magically knowing that eval frames have
497 an info pointer sitting after vect.
498 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
500 (scm_init_stacks): Formatting tweaks.
502 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
504 Give GCC more control flow information, so it can be sure that
505 variables aren't used uninitialized.
506 * error.h (scm_error, scm_syserror, scm_syserror_msg,
507 scm_sysmissing, scm_num_overflow, scm_out_of_range,
508 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
509 scm_misc_error): Tell GCC that these functions never return.
510 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
511 out the field type, call abort if SCM_ASSERT returns, to placate
513 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
514 scm_wta ever returns. We can't handle this case anyway, and this
515 gives the optimizer more information.
516 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
517 scm_wta ever returns.
519 In some cases, the code is fine, but GCC isn't smart enough to
520 figure that out; this usually happens when one variable is only
521 initialized and used when a particular condition holds true, and
522 we know that condition will never change within a given invocation
523 of the function. In this case, we simply initialize the variables
524 to placate the compiler, hopefully to a value which will cause a
525 crash if it is ever actually used.
526 * print.c (scm_iprin1): Initialize mw_pos.
527 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
528 * throw.c (scm_ithrow): Initialize dynpair.
529 * unif.c (scm_uniform_vector_ref): Initialize cra.
530 * struct.c (init_struct): Initialize prot.
531 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
533 * strports.c (scm_eval_0str): Don't return uninitialized garbage
534 if EXPR contains no expressions.
536 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
538 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
539 cause an infinite loop (???). So much for the algebraic
540 equivalency of variable-sized arrays and alloca...
542 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
544 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
545 a SCM boolean, not a C boolean.
547 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
549 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
550 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
551 rules for raising scm_mtrigger. Previously, unfortunate but not
552 unlikely circumstances could result in almost constant invokation
553 of the gc. Now, this situations should be less likely, but they
554 are not prevented completely.
556 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
558 * numbers.c (scm_fuck): Procedure removed; looks like old test
560 * numbers.h: Prototype removed.
562 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
564 * debug.h (scm_debug_frame): Change `vect' member from an in-line
565 array to a pointer, to match my Nov 21 change in eval.c.
567 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
569 * libguile.h: Added #include "libguile/backtrace.h", #include
572 * strings.c (scm_string scm_make_string scm_string_ref
573 scm_string_set_x scm_string_equal_p scm_string_append):
574 Bugfix according to scm patch from Aubrey Jaffer:
575 Corrected long-standing
576 (not (eqv? (integer->char 128)
577 (string-ref (make-string 1 (integer->char 128)) 0)))
578 bug found by John Kozak <jk@noontide.demon.co.uk>.
580 * strports.c, strports.h: Make scm_eval_0str return the value of
581 the last expression evaluated (previously, it returned void).
583 * strports.c, strports.h: New function: scm_read_0str. Does what
586 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
588 * simpos.c (scm_getenv): return #f if string can't be found in the
589 environment instead of throwing an exception, for compatibility
590 with numerous other systems.
592 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
594 * Makefile.am (.c.x): Use guile-snarf.
595 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
597 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
599 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
601 * backtrace.c (scm_display_error_message): Made non-static, and
602 renamed from display_error_message.
603 * backtrace.h (scm_display_error_message): Added extern decl.
604 * throw.c (uncaught_throw): Use it to display the error message.
606 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
608 * inet_aton.c: Use #if 0, not #ifdef 0.
610 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
612 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
613 to convert the returned value.
614 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
617 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
619 Add new interface to catch/throw, usable from C as well as
621 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
622 (scm_internal_catch): New function, replaces...
623 (scm_catch_apply): Deleted.
624 * throw.c (scm_catch_apply): Deleted; replaced with a more general
625 mechanism which is a bit more code, but can be used nicely from C
626 and implement the Scheme semantics as well.
627 (scm_internal_catch): This is the replacement; it's named after
628 the analogous function in Emacs.
629 (scm_catch): Reimplemented in terms of the above.
630 (struct catch_body_data, catch_body, catch_handler): New
631 functions, used by scm_catch.
632 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
633 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
634 support for new cwdr.
636 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
639 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
641 * acconfig.h: Added DYNAMIC_LINKING symbol.
642 * configure.in: Add option and checks for dynamic linking.
643 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
644 dynl.h: New files for dynamic linking support.
645 * Makefile.am (libguile_a_SOURCES):
647 (modinclude_HEADERS): Added "dynl.h".
648 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
650 * init.c (scm_boot_guile_1): Call
651 scm_init_dynamic_linking to initialize dynamic linking support.
653 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
655 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
656 (as we Schemers say). It needs to be global, so that I can tweak
657 it for the proper operation of unexec.
658 (scm_boot_guile_1_live): New variable, see above.
660 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
662 * guile-snarf.sh: Removed.
663 * PLUGIN/guile.libs: Added dependency for -lm.
664 * acinclude.m4: Renamed from aclocal.m4.
665 * PLUGIN/greet: Removed.
666 * Makefile.am, aclocal.m4: New files.
667 * configure.in: Updated for Automake.
669 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
671 * eval.c (scm_definedp): Use top_level_lookup_closure_var
672 and not top_level_lookup_thunk_var.
674 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
676 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
678 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
680 * eval.c (scm_definedp): Incompatibly changed to be a builtin
681 Scheme function, instead of syntax. Single argument is now a
684 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
686 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
687 scm_ra_divide): Properly terminate statements passed as arguments
688 to IVDEP macros. (Thanks to Bernard Urban.)
690 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
691 with non-constant sizes. (Thanks to Bernard Urban.)
693 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
695 It's an "eval closure", not an "eval thunk." A thunk is a
696 function of no arguments.
697 * root.h (struct scm_root_state): Renamed
698 top_level_lookup_closure_var from top_level_lookup_thunk_var.
699 (scm_top_level_lookup_closure_var): Renamed from
700 scm_top_level_lookup_thunk_var.
701 * root.c (mark_root): Uses changed.
702 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
703 * init.c (scm_start_stack): Uses changed.
704 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
705 Change scheme-visible name to *top-level-lookup-closure* from
706 *top-level-lookup-thunk*.
708 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
710 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
711 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
713 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
715 * gc.c (struct scm_heap_seg_data): Doc fixes.
717 * gc.c (scm_gc_sweep): Empty all segments' freelists before
718 sweeping. Then, prepend each segment's free cells to its
719 freelist, rather than wiping out the old value. (Thanks to Marius
722 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
723 scm_check_freelist, scm_debug_newcell): New functions and
724 variables, for debugging freelist problems.
725 * pairs.h (SCM_NEWCELL): New debugging version added.
726 * gc.h (scm_debug_newcell): Added extern declaration, used by
727 debugging version of SCM_NEWCELL.
729 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
731 On some systems <libc.h> conflicts with <unistd.h>, and should not
733 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
734 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
735 * configure.in: Call it.
736 * posix.c, filesys.c: Use its results to decide whether or not to
738 * configure, scmconfig.h.in: Rebuilt with autoconf and
741 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
743 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
744 pointer to the stdio stream before calling scm_setbuf0, so the
745 latter will be able to retrieve it. I'm surprised this didn't
746 segfault earlier. (Thanks to Christopher Lee.)
748 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
750 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
753 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
755 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
756 number of stack narrowing specifier pairs. The first specifier in
757 a pair controls inner border, the second the outer border. A
758 number means cut that number of frames, a procedure object means
759 cut until that object is found in operator position in a frame.
761 * root.c (cwdr): Bugfix.
763 * read.c: Recording of positions disabled by default.
765 * procs.c (scm_closure_p): New function.
767 * posix.c (scm_tmpnam): New function.
769 * load.c: Added #include "throw.h".
770 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
773 * load.c, load.h (scm_read_and_eval_x): New function.
775 * eval.c: Renamed debug option "deval" to "debug".
777 (scm_eval_x): `eval!' is no longer accessible from the scheme
778 level. Motivation: We can't allow operations which introduce
779 glocs into the scheme level. Guile's type system can't handle
780 these as data. Use `eval' or `read-and-eval!' as replacement.
782 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
783 SCM_CONSP since this is a macro!; Set vframe.prev to
784 scm_last_debug_frame instead of 0. In this way we can look
785 "above" the virtual start stack frame if we wish.
786 (scm_debug_hang): New function: Useful for debugging Guile in
787 certain tricky situations. Will probably be removed later...
789 * debug.h: Changed semantics of debug option "backtrace". This
790 option now only indicates whether we want automatic backtrace at
793 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
795 * ports.c: #include "filesys.h"
796 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
798 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
799 Motivation: This is system specific code which is related to file
800 I/O. It also may use select. Added code by Gary Houston to
801 detect presence of character in stdio buffers.
803 * libguile.h: #include "libguile/libpath.h"
805 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
806 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
807 SCM_SITE_DIR; Install libpath.h among the other include files.
809 * load.c, load.h (scm_sys_package_data_dir): New function.
811 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
813 * stacks.h: Bugfix: Don't use tail-array length field as stack
814 length field! This screwed GC.
816 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
818 * _scm.h: Added #ifndef around definition of macros min and max.
820 * __scm.h: Added hooks for threads to plugin to in ints protection
821 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
822 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
823 the main code in these macros duplicated and spread over multiple
824 files. Renamed SCM_THREADS_SWITCHING_CODE ->
825 SCM_THREAD_SWITCHING_CODE.
827 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
830 * guile-snarf.sh: New file.
831 * Makefile.in (inner_h_files): Added snarf.h
832 (ancillary, install, uninstall, distclean): Added actions for
834 (.c.x): Use guile-snarf.
835 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
836 (gen_c_files): Note that these depend on guile-snarf.
837 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
838 now in "snarf.h". Added #include "snarf.h" to get them.
839 * libguile.h: Added #include "snarf.h".
840 (Patches applied and tweaked by Jim Blandy.)
842 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
844 * socket.c: Use K&R style declaration for 'close'; the GNU coding
845 standards suggest against providing prototypes for system
846 functions. Thanks to Greg Troxel.
848 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
850 * strports.c (scm_eval_0str): New function.
851 #include "read.h", to get prototype for scm_read.
852 * Makefile.in (strports.o): Update dependencies.
853 * strports.h: New prototype.
855 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
856 scheme name from "int?" to "integer?". It seems to do the job.
857 * numbers.h: Rename prototype too.
858 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
861 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
862 scm_num_eq_p): Rename these according to R4RS conventions: call
863 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
864 to making libguile R4RS compliant without ice-9...
866 * load.c (scm_sys_search_load_path): Search for files under all
867 extensions listed in the %load-extensions variable. If FILENAME
868 is absolute, return it unchanged, without searching the load path.
869 (scm_loc_load_extensions): New variable, pointing to
870 %load-extensions' value cell.
871 (scm_init_load): Initialize it, and the value it points to.
872 (scm_primitive_load_path): Improve error reporting.
874 * load.c (scm_loc_load_hook): New variable, pointing to value cell
875 of new Scheme variable %load-hook.
876 (scm_primitive_load): Apply %load-hook to filename.
878 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
880 * configure.in: add tests for figuring out whether buffered data
881 is available in a FILE structure, which is needed by char-ready.
883 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
886 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
887 exceptions using misc_error instead of syserror. It seems a bit
888 odd to throw an exception if a string can't be found in the
889 environment, but it's consistent with open-file, stat etc.
890 (simpos.h): remove sys_ from getenv.
892 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
893 occurs, throw an error instead of returning errno. Return value
895 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
897 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
899 * filesys.c (scm_stat2scm): derive file type and permissions from
900 the stat mode and append them to the returned vector.
901 There isn't much overhead in doing this and it avoids the need to
902 work with S_IRUSR et al. in Scheme.
903 Define symbols scm_sym_regular etc.
904 (scm_init_filesys): don't intern S_IRUSR etc.
906 * load.c: change s_try_load and s_try_load_path to s_primitive_load
907 and s_primitive_load_path.
909 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
911 * error.h: don't declare error symbols. prototype for scm_misc_error.
913 * stackchk.c (scm_stack_overflow_key): defined here instead of in
916 * error.c: use SCM_SYMBOL to set up error keys.
917 scm_misc_error: new procedure.
919 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
921 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
922 between `#!' and `!#' is ignored.
923 (skip_scsh_block_comment): New function.
925 * feature.c (scm_set_program_arguments): New argument, FIRST.
926 * feature.h: Update prototype.
927 * init.c (scm_boot_guile_1): Pass new argument to
928 scm_set_program_arguments.
930 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
932 * init.c (scm_start_stack): Don't initialize scm_progargs here.
933 (scm_boot_guile): Call scm_set_program_arguments here, later than
934 the old initialization.
936 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
937 initialization procedure.
938 - Delete in, out, err arguments; there are other perfectly good
939 ways to override these when desired.
940 - Delete result argument; this function shouldn't ever return.
941 - Rename init_func argument to main_func, for less confusion.
942 - Delete boot_cmd argument; main_func is more general.
943 -Add 'closure' argument, to help people pass data to main_func
944 without resorting to global variables.
945 - Abort if reentered; don't bother returning an error code.
946 - Call scm_init_standard_ports to set up the default/current
947 standard ports; no need to pass them to scm_start_stack.
948 - Remove code to evaluate the boot_cmd, and start the repl; let
949 the user do something like that in main_func if they want.
950 - Remove code to package up a return value; main_func can do any
952 - Call exit (0), instead of returning.
953 (scm_start_stack): Don't initialize the I/O ports here; that's
954 weird. Delete in, out, err arguments. Move guts to
955 scm_init_standard_ports, scm_stdio_to_port.
956 (scm_init_standard_ports): New function, to set up current and
957 default standard ports.
958 (scm_start_stack, scm_restart_stack): Make these static.
959 * init.h (scm_boot_guile): Adjust declaration.
960 (scm_start_stack, scm_restart_stack): Remove externally
961 visible declarations for these.
962 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
964 * fports.c (scm_stdio_to_port): New function. Its guts used to be
965 written out several times in scm_start_stack.
966 * fports.h: New declaration for the above.
968 * feature.c (scm_set_program_arguments): New function.
969 * feature.h: New declaration for the above.
971 * ports.c: Formatting tweak.
973 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
975 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
976 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
977 for obtaining the address of a car or cdr field. Motivation:
978 &SCM_CXR make assumptions about the internal structure of the
981 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
982 Motivation: see SCM_CXRLOC.
984 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
985 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
986 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
987 Motivation: Safer use. Some other macros are defined in terms of
988 these operations. If these are defined using the SCM_SETCXR
989 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
990 to inefficiency and an <e1> with side-effects could potentially
991 break. Also, these particular operations are heavily utilized in
992 the garbage collector. In unoptimized code there will be a
995 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
996 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
997 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
998 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
999 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
1000 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1001 vports.c: Cleaned up use of pairs: Don't make any special
1002 assumptions about the internal structure of selectors and
1003 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1004 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1005 (Among other things, this change makes it easier to build Guile
1006 with certain compilers which have problems with casted lvalues.)
1008 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1010 * stacks.c: Improve selection of relevant stack frames when making
1011 a stack object. Introduce one level of indirection in the stack
1012 object to make it possible to "narrow" to a certain region of the
1013 stack. This facilitates making use of more clever algorithms (not
1014 implemented) for selecting relevant frames and gives a cleaner
1015 design since selection of frames can be done independently of
1016 extraction of frames from the real stack.
1017 (scm_stack_id): Also take #t as argument which means look at
1020 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1021 Turn n_tail into an integer directly representing current number
1022 of frames in stack. Add field tail.
1024 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1026 * debug.c (scm_make_memoized): Made it available at scheme level.
1027 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1028 SCM_NIMP before applying heavier predicates in argument checking.
1029 (scm_local_eval): Also take memoized object as argument.
1031 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1032 aren't created with zero length, but should such a strange
1033 creature suddenly turn up...
1035 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
1037 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
1038 `del', for the sake of C++ compilers. (Patch applied by JimB.)
1040 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
1042 * variable.c (scm_make_variable): Make the name hint optional, as
1044 (anonymous_variable_sym): Renamed from variable_sym. All uses
1047 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
1048 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
1049 of scm_primitive_load_path was also changed to
1050 "primitive-load-path", from "%try-load-path". Callers changed.
1051 We'd like to respect the convention that a function named
1052 "try-mumble" should behave just like the function called "mumble",
1053 but return #f instead of signalling some error.
1054 * load.h: Rename prototypes.
1056 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1058 * print.c (make_print_state, grow_print_state), print.h: Modified
1059 the print state representation: Don't use a tail array for
1060 recording of circular references. Resizing of the print state
1061 structure invalidates the print state pointer. To avoid passing
1062 around an indirect print state reference to all printing
1063 functions, we instead let the print state reference a resizable
1066 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
1068 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
1069 Don't crash when passed an improper list terminated by a
1070 non-immediate value.
1072 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
1074 Allocate data for structures on an eight-byte boundary, as
1075 required by the tagging system.
1076 * struct.c (alloc_struct): New function.
1077 (scm_make_struct, scm_make_vtable_vtable): Call it.
1078 * struct.h (scm_struct_n_extra_words): Bump to 3.
1079 (scm_struct_i_ptr): New "field".
1080 * gc.c (scm_gc_sweep): When we need to free the data, use the
1081 information stored by alloc_struct to find the beginning of the
1082 block allocated to the structure, so we can free it.
1084 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1086 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
1089 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
1090 (scm_debug_info): New member: id.
1092 * stacks.c: Stacks are now represented as structs; Stacks have an
1093 id given to them by `start-stack'.
1094 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
1096 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
1097 Changed stack representation.
1099 * debug.c (scm_procedure_name): Try procedure property `name' for
1100 compiled closures aswell.
1102 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
1104 * eval.c: scm_i_name moved to gsubr.c
1105 (scm_m_define): Record names of all kinds of procedure
1106 objects. (Earlier, only closures were recorded.)
1108 * procprop.h: Added declaration of scm_i_name.
1110 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
1111 (scm_make_gsubr): Record names of compiled closures.
1113 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1115 * debug.c, debug.h: Removed obsolete code.
1117 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
1118 stacks.c: Renamed regs --> scm_contregs.
1120 * print.c (scm_free_print_state): Cleanup print state before
1121 returning it to pool. It is better to do it here than in
1122 scm_prin1 since scm_prin1 is called often.
1124 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
1125 s_set_source_property_x): Check that first argument is a pair or a
1128 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
1129 scm_i_line, scm_i_column and scm_i_breakpoint global.
1131 * init.c: Added #include "backtrace.h" and #include "stacks.h".
1132 (scm_boot_guile_1): Added calls to scm_init_backtrace and
1135 * debug.h: Added debug object smob declaration and macro
1138 * configure.in: Build with backtrace.o and stacks.o if debug
1141 * Makefile.in: Added entries for new files: backtrace.c,
1142 backtrace.h, stacks.c and stacks.h.
1144 * symbols.c (scm_sym2ovcell): Fixed documentation.
1146 * _scm.h (min, max): Added.
1148 * async.c: Moved `min' macro to _scm.h.
1150 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
1151 SCM_BACKTRACE_INDENT.
1153 * eval.c: Added new debug options `maxdepth' and `indent'.
1155 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
1157 * print.h: Added selector SCM_PRINT_STATE.
1159 * print.c: New functions: scm_make_print_state,
1160 scm_free_print_state.
1162 * print.h: Added declarations for scm_make_print_state,
1163 scm_free_print_state.
1165 * debug.c (scm_m_start_stack): New acro.
1167 * debug.h: Small cleanup.
1169 * init.c (scm_boot_guile_1): Moved scm_init_debug below
1172 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

1194 declare functions with prototypes. (Patch thanks to Marius
1197 More prototype-related changes from Marius Vollmer:
1198 * gdb_interface.h: Wrapped header file in #ifdef/#endif
1199 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
1200 * ports.h (ptobfuns): Added prototypes. This means some casting in
1202 * fports.c: Added casts for initializations, since the functions
1203 are defined to take FILE * as their stream argument, not SCM.
1204 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
1205 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
1206 to `char *str_data' to conform to prototype.
1208 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1210 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
1212 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
1214 * stime.c, stime.h: use SCM_P method.
1216 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1218 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
1219 be given at least two arguments. Insist that lst's last element
1220 be a list, but don't make any requirements of its predecessors.
1222 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
1224 * eval.c (scm_nconc2last): Revert last change; there seems to be
1225 other stuff going on here.
1227 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1229 * eval.c (scm_nconc2last): Make sure that each element of lst
1230 (which is a list of argument lists, except for the tail) is a
1231 proper list, i.e., finite and terminated by '().
1233 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1235 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
1238 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
1239 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
1242 * vectors.c (scm_make_vector): Fill vectors with the undefined
1243 value, to help make Guile Scheme code more portable to other
1246 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
1247 * symbols.h, tags.h: Doc fixes.
1249 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
1251 * async.c (scm_take_signal): Doc fixes.
1253 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
1255 * numbers.c (scm_divbigint): When the remainder is zero, we don't
1256 want to subtract it from the modulus; we just want to leave it
1259 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
1261 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
1264 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
1266 * throw.c (scm_catch_apply): Finished implementation of
1269 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
1271 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
1273 (scm_init_filesys): set "i/o-extensions" feature.
1276 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
1278 * Makefile.in (root.o): Correct dependencies.
1280 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
1282 * Makefile.in: Added dependency entry for root.o.
1284 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
1285 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
1287 * init.c (scm_start_stack): Set initial root continuation number
1290 * procs.c: New function: scm_thunk_p.
1292 * procs.h: Added declarations of scm_thunk_p.
1294 * root.c: Renamed `call-with-new-root' -->
1295 `call-with-dynamic-root'.
1296 (cwdr): Removed allocation of new root state. This should be done
1297 separately by use of scm_make_root.
1298 (scm_apply_with_dynamic_root): New function: Does what it
1299 sounds like. Needed when spawning threads.
1301 * root.h: Added member last_debug_frame to root state.
1302 Added #include "libguile/debug.h"
1304 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
1305 arguments. The motivation is that code in root.c needs catch
1306 functionality, and we want to avoid code duplication.
1307 New functions: scm_catch, scm_lazy_catch. These are wrappers for
1308 scm_catch_apply. scm_lazy_catch is intended to introduce catch
1309 handlers that run without popping the stack into the dynwind
1312 * throw.h: Added prototypes for scm_catch_apply and
1315 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1317 * root.h (scm_root, scm_set_root): Decouple thread support details
1318 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
1319 SCM_SET_THREAD_LOCAL_DATA.
1321 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
1322 and tortoise scanning loop.
1324 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
1326 * Makefile.in: Rebuild dependencies.
1328 * libguile.h: #include "libguile/print.h" before "smob.h", since
1329 the latter uses the print_state structure.
1331 * throw.c (scm_ithrow): Use the correct variable when checking to
1332 see if a given element of scm_dynwinds is a valid catch.
1334 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
1335 structure, abort; don't just silently ignore the garbage.
1337 * _scm.h: #include "print.h" here, since it seems to be used just
1339 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
1340 strports.c, unif.h: Don't #include "print.h".
1342 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1344 * feature.h (scm_loc_features): Removed external declaration.
1345 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
1347 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1349 * feature.c (scm_init_feature): Added threads feature (needs to be
1350 initialized here, since features doesn't exist when
1351 scm_init_threads is called).
1353 * libguile.h: Added #include "libguile/../threads/threads.h".
1354 (This is a kludge to get thread support working. This should be
1357 * configure.in, acconfig.h: Added flags for thread support.
1359 * scmsigs.c: Define `signal' to be `pthread_signal' if using
1362 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
1363 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
1366 * _scm.h: Added conditional #include "threads.h"
1368 * __scm.h (SCM_ASYNC_TICK): Added call to macro
1369 SCM_THREADS_SWITCHING_CODE.
1371 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
1372 allocate the basic dynamic root object.
1373 (scm_boot_guile): Added call to scm_init_root.
1375 * root.c, root.h: Added root smob.
1376 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
1377 functions: Implements dynamic roots mostly according to spec in
1378 SCM manual. Main difference is that the second argument is a
1379 throw handler rather than an error "thunk".
1381 * root.h: Added declaration of scm_init_root.
1383 * root.c: Added #include "genio.h", #include "smob.h", #include
1384 "pairs.h", #include "throw.h", #include "dynwind.h", #include
1386 (scm_init_root): Added #include "root.x".
1388 * throw.c: Added #include "stackchk.h"
1389 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
1390 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
1391 can be used in scm_call_with_new_root; Added reenabling of stack
1392 checking when catching a throw.
1394 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
1396 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
1398 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
1399 element is not found, as per R4RS.
1401 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1403 * list.c: Doc fixes throughout.
1405 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1407 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
1408 declare the char * to be const. Avoids a warning in rgx.c.
1410 * ports.h: spelling fix.
1412 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
1415 * load.c (scm_sys_try_load_path): throw an error if file not found
1416 (like it says it in NEWS).
1418 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
1420 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
1421 PROPS slot to '(), not #f; it's an empty alist.
1423 * throw.h, throw.c: Use SCM_P instead of #if hair.
1425 Remove special support for uncaught throws; see throw.c for
1427 * throw.c (uncaught_throw): New function.
1428 (scm_ithrow): Call uncaught_throw if we don't find a throw
1429 target; don't mess with scm_bad_throw_vcell.
1430 (scm_bad_throw_vcell): Variable deleted.
1431 (scm_init_throw): Don't initialize it.
1433 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
1436 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1438 * numbers.c (scm_istr2int): If the number is short (as most
1439 numbers are), just call scm_small_istr2int to deal with it.
1440 (scm_small_istr2int): New function, created by un-#ifdefing the
1441 non-bignum version of scm_istr2int and renaming it.
1443 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
1445 * load.c (scm_sys_try_load): don't check whether value returned
1446 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
1447 Change the Scheme name from %try-load to primitive-load.
1449 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
1450 Can avoid passing a message, allowing it to be derived in the
1451 error handler (e.g., if we want to throw to the key both from
1454 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
1456 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
1457 references now have a new appearance which is more compact and
1458 also gives a clue about what the target of the reference is.
1459 By setting parameters in the print state, more fancy printing can
1460 be achieved. This is used by the (not yet commited) backtrace
1463 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
1465 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
1468 * print.c: Added #include "struct.h". Removed function
1471 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
1472 scm_iprin1. Removed prototype for scm_prlist.
1474 * arbiters.c (prinarb),
1475 async.c (print_async),
1476 debug.c (prindebugobj, prinmemoized),
1477 eval.c (prinprom, prinmacro),
1478 filesys.c (scm_fd_print, scm_dir_print),
1480 mallocs.c (prinmalloc),
1481 numbers.c, numbers.h (scm_floprint, scm_bigprint),
1482 smob.h (scm_smobfuns),
1483 srcprop.c (prinsrcprops),
1485 unif.c, unif.h (scm_raprin1, rapr1),
1486 variable.c (prin_var): Changed argument `int writing' to
1487 `scm_print_state *pstate'.
1489 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
1490 that it will be called before scm_init_print.
1492 * print.c (scm_prin1): Print states are now allocated when calling
1493 scm_prin1 and then passed around to all printing functions as an
1494 argument. A cache `print_state_pool' enables reuse of print
1496 (scm_make_print_state): New function.
1497 (scm_iprin1): Adaption to print states.
1498 (scm_iprlist): An initial "hare and tortoise" scan brings down
1499 time complexity to O (depth * N). (Better time complexity will be
1500 achieved when the printing code is completely rewritten.)
1502 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1504 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
1505 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
1506 it gets done whether or not the cache variable has a value.
1508 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
1510 Distinguish #f and ().
1511 * __scm.h: #undef SICP.
1512 * pairs.h (SCM_EOL): Delete this definition, equating it with
1514 * tags.h (SCM_EOL): Give it a new definition here; I think I found
1515 the value it used to have. Doc fixes, too.
1517 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
1519 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
1520 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
1521 Lord's implementation of structs, allowing for tail arrays as
1522 described in the manual. Also fixed some bugs. (Both the interface
1523 and the implementation should be improved.)
1525 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
1527 * print.c, print.h: Closures now print like #<procedure foo (x)>.
1528 People who whish to see the source can do `(print-enable 'source)'.
1529 Removed #ifdef DEBUG_EXTENSIONS.
1531 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1533 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
1534 integer (assuming for now accepting an integer is a good thing).
1536 * error.c, fports.c: replace use of %S in lgh_error args with %s.
1537 %S will be used instead for write'ing arguments.
1539 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
1540 asserts. fix a few other asserts.
1541 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
1542 scm_uniform_vector_ref, scm_array_set_x,
1543 scm_dimensions_to_unform_array): change args in
1544 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
1545 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
1546 scm_substring_fill_x): likewise.
1547 gsubr.c (scm_gsubr_apply): likewise.
1548 eval.c (SCM_APPLY): likewise.
1550 * eval.c (4 places): replace scm_everr with lgh_error or
1553 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
1554 scm_memory_error): new procedures.
1555 scm_everr: deleted. can use scm_wta, dropping first two args.
1556 scm_error: convert NULL subr to SCM_BOOL_F.
1558 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
1561 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
1564 * error.c, error.h: new error keys: scm_arg_type_key,
1565 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
1567 scm_wta: reimplement using lgh_error instead of scm_everr.
1569 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
1571 * gdbint.c: scm_lread now has one more argument.
1573 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
1574 scm_port_\1; Added mutator scm_set_port_filename_x (used when
1575 loading source from non-file ports, which, e. g., happens when
1576 using the Emacs interface).
1578 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
1581 * read.c: Added code for recording of positions of source code
1582 expressions; New functions: recsexpr, scm_lreadrecparen;
1583 _scm_make_srcprops --> scm_make_srcprops
1584 (scm_flush_ws): Removed updating of positions counters. This work
1585 is already done by scm_gen_getc
1587 * read.h: Added prototype for scm_lreadrecparen
1589 * print.c: Added #include "alist.h"
1591 * eval.c: Added #include "hash.h"
1593 * eq.c: Added #include "ramap.h"
1595 * options.c: Documentation fixes.
1597 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
1598 (scm_init_srcprop): Adjusted size of initial source-whash. Name
1599 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
1600 --> scm_make_srcprops
1602 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
1603 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
1604 function calls in the definition of the whash access macros.
1606 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
1608 * init.c (scm_boot_guile): Add level of indirection to
1609 scm_boot_guile_1() to ensure that stack base pointer is properly
1610 initialized. There was no guarantee that variable i was the
1611 highest/lowest variable on stack (i.e. the call frame of
1612 scm_boot_guile was not completely protected from gc).
1614 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
1616 * ports.h (scm_port_table): put back file_name, it will be used to
1617 support debugging. Undo related changes in fports.c, ioext.c,
1620 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
1622 * ports.h (scm_port_table): remove file_name member for now, it seems
1624 * fports.c (scm_open_file): don't set file_name in PTAB.
1625 (prinfport): don't use file_name in PTAB.
1626 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
1627 * ports.c (scm_add_to_port_table): don't intialize file_name.
1628 (scm_port_file_name): remove for now.
1629 * gc.c (scm_gc_mark): don't mark PTAB file_name.
1631 * fports.h (scm_mkfile): prototype deleted.
1632 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
1634 * debug.c, unif.c: use scm_out_of_range instead of
1635 wta for range errors (ASSERT still needs work).
1637 * error.c, error.h (scm_out_of_range): new procedure.
1639 * error.c, error.h (scm_out_of_range_key): new key.
1641 * posix.c (scm_sync): #else was missing.
1643 * error.c, error.h: append _key to names scm_num_overflow and
1646 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
1647 of consing an empty list.
1648 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
1649 of macros, saves code and string space.
1650 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
1651 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
1652 lower case. Rename scm_syserror_m to scm_syserror_msg.
1653 error.h: prototypes for new procedures.
1655 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
1657 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
1659 * error.c, error.h: setup scm_num_overflow key.
1661 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
1662 Remove definition of SCM_OVSCM_FLOW.
1664 * fports.c (scm_open_file): use SCM_SYSERROR_M.
1666 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
1667 explicit message and args.
1669 * error.c, error.h, __scm.h: change system_error_sym to
1672 * error.c (system_error_sym): remove leading %% from the Scheme name
1675 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
1677 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1679 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
1680 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
1681 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
1682 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
1683 renamed. (These were introduced by unsupervised name
1686 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1688 * print.c: Added code for detection of circular references during
1689 printing. (init_ref_stack, grow_ref_stack): New functions. Added
1690 a hook for printing of closures (accessible via print options).
1691 This leads to a split of calls to scm_iprin1 into two classes:
1692 elementary print operations (e. g. the code which prints a smob)
1693 still use scm_iprin1 while top level calls (like scm_display) use
1694 scm_prin1. scm_prin1 begins by clearing the data structure used
1695 to record reference information.
1697 * print.h: Added declarations of scm_prin1 and scm_prlist.
1699 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
1701 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
1703 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
1705 * error.c (err_head): scm_iprin1 --> scm_prin1
1707 * debug.c: Adjusted header comment.
1711 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
1713 * strerror.c: Doc fix.
1715 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
1717 * gdbint.c (gdb_read): Now possible to run during GC.
1718 (unmark_port, remark_port): New functions.
1720 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
1722 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
1723 of allocating a new string object. Also, increase size by
1724 the factor 2 instead of 1.5.
1726 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
1728 * __scm.h (SCM_P): Corrected to run under traditional C.
1730 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
1733 * async.c: Calls to scm_sysintern corrected.
1735 * async.h (scm_async_clock): Redundant declaration removed.
1737 * continuations.c (scm_dynthrow): Redundant declaration removed.
1739 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
1740 Definition typos corrected.
1742 * debug.h: Missing declarations of functions in debug.c added
1745 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
1746 Missing declarations to functions in eval.c added.
1748 * filesys.c: Possibly uninitialized variable rv.
1750 * gc.h (scm_object_addr, scm_unhash_name): Missing
1751 declarations of functions defined in gc.c added.
1753 * genio.c: Possible typos str_data -> wstr_data. ???
1755 * genio.c: Possibly unintended shadowing of local variable
1756 `int c' (gotos out of scope of inner `c'). ???
1758 * init.c: Uninitialized `SCM last' may be used.
1760 * ioext.h: (scm_sys_isatty_p): Typo.
1762 * list.h (scm_list_head): Missing prototype for function in
1765 * numbers.c (scm_two_doubles): Changed from extern to static
1766 (is used only within numbers.c).
1768 * numbers.h: Repeated declarations removed.
1770 * ports.h (scm_close_all_ports_except): Declaration for the
1771 function defined in ports.c added.
1773 * posix.h: Missing declarations added.
1775 * procs.h (scm_make_subr_opt): Missing declaration added.
1777 * socket.h (scm_sys_gethost): Missing declaration added.
1779 * socket.h: Redundant declarations removed (they are in fdsocket.h).
1781 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
1782 Missing declarations added.
1784 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
1786 * struct.c: Uninitialized variable `SCM answer' may be used.
1788 * unif.c (l2ra): Declaration prototype.
1790 * unif.c (scm_array_equal_p): Dummy definition removed (it is
1791 defined in ramap.c).
1793 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
1794 Redundant declarations removed (they are in ramap.h).
1796 * variable.h (scm_make_udvariable,
1797 scm_make_undefined_variable): Declaration corrected to
1798 correspond variable.c.
1800 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
1801 Missing declarations added.
1803 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
1805 * Makefile.in (distclean): Don't forget to delete fd.h.
1807 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1809 * fd.h.in, tags.h: Trivial cleanups.
1811 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
1812 marksweep.h just declared functions from gc.c.
1813 * gc.h, libguile.h: Don't #include "marksweep.h".
1814 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
1815 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
1816 dependencies updated.
1818 * libguile.h: Don't #include "files.h"; it's been deleted.
1820 * files.c (scm_sys_delete_file): Moved to filesys.c.
1821 File is now empty; deleted.
1823 * filesys.c: scm_sys_delete_file is now here. Remove
1824 #if's; they seem to rely on remnants of an old portability
1825 regimen. If the problems come up again, solve them properly,
1826 using autoconf. Specifically: Don't test M_SYSV, and #define
1827 remove to be unlink if it's #defined; don't use remove just
1828 because HAVE_STDC_HEADERS is #defined.
1829 * filesys.h: Add declarations for scm_sys_delete_file.
1830 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
1831 files.o, files.h, files.c, and files.x.
1832 * init.c: Don't #include "files.h", and don't call scm_init_files.
1834 Use SCM_P instead of PROTO; the latter intrudes on the user's
1836 * params.h: Deleted; definition of SCM_P moved to...
1837 * __scm.h: ... here, where it replaces PROTO macro.
1838 * libguile.h, smob.h: Don't #include "params.h".
1839 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
1840 smob.h: Fix prototypes accordingly.
1841 * Makefile.in: Update dependencies.
1842 (inner_h_files): Remove params.h.
1844 * gc.c: #include "gc.h"; every module should include its header,
1845 to let the compiler cross-check the declarations against the
1848 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
1849 simpos.h: #include "libguile/__scm.h".
1851 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
1853 * init.c: Don't forget to #include smob.h and init.h.
1854 * Makefile.in: Dependencies updated.
1856 * smob.h: Use PROTO instead of #if __STDC__.
1858 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
1860 * __scm.h: Doc fixes.
1862 * __scm.h, libguile.h: Use "quotes" in the #includes, not
1863 <angles>; this allows `make depends' to work properly.
1865 * libguile.h: #include smob.h and pairs.h before the others; they
1866 define typedefs used by other headers.
1868 C files should #include only the header files they need, not
1869 libguile.h (which #includes all the header files); the pointless
1870 recompilation was wasting my time.
1871 * Makefile.in (all .o dependency lists): Regenerated.
1872 * libguile.h: Don't try to get a definition for size_t here...
1873 * __scm.h: Do it here.
1874 * _scm.h: Since this is the internal libguile header, put things
1875 here that all (or a majority) of the libguile files will want.
1876 Don't #include <libguile.h> here; that generates dependencies on
1877 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
1878 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
1879 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

1978 * stackchk.h: #include "libguile/debug.h",
1980 * print.h, read.h: #include "options.h", since everyone who uses
1981 either of these files will need that.
1983 * smob.h: #include "ports.h", "genio.h", and "print.h", since
1984 anyone who uses this file will need them to define the smob
1985 printing functions. Also, get markers.h, since people will need
1986 to #define the mark functions.
1988 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
1989 * ports.h: ... to here.
1991 * ports.h (scm_port_table_size): Explicitly give type as 'int';
1992 don't rely on archaic C default type rules.
1994 * fports.h: #include "libguile/ports.h", since you need that in
1995 order to parse this.
1997 * genio.h: #include "libguile/print.h", because you need that to
1998 parse this; don't bother #including "ports.h", since print.h gets
2001 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2003 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2004 this; it's now a reference to an element of *scm_root.
2006 * debug.h: Don't #include "options.h"; the compiler won't be able
2007 to find that once the headers are installed; instead, #include
2008 "libguile/options.h".
2009 * gc.h: Same, with marksweep.h.
2010 * mbstrings.h: Same, with symbols.h.
2011 * scmhob.h: Same, with _scm.h.
2012 * smob.h: Same, with params.h.
2014 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2015 C files; there's no need for this, and it forces recompilations
2018 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2020 * error.c (scm_error): declare scm_error_callback.
2022 * error.h: prototype for scm_error_callback.
2024 * __scm.h: define lgh_error.
2025 (SCM_SYSERROR): redefine using lgh_error.
2027 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2029 * error.c (scm_error): new procedure.
2031 * error.h: prototype for scm_error.
2033 * Makefile.in (install): install scmconfig.h from the current
2034 directory, not $(srcdir).
2036 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2038 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2039 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2040 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

2046 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2047 vports.h, weaks.h: #include "libguile/__scm.h", not
2048 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
2049 dependencies are within libguile properly.
2051 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
2053 * Makefile.in (.c.x): Simplify; there's no need to run this rule
2054 when scmconfig.h doesn't exist.
2056 * load.c (scm_sys_try_load): Correct spelling.
2058 * feature.c (scm_loc_features): Make this static.
2060 * Makefile.in (libpath.h): Omit trailing slash from path. We
2061 shouldn't require it of users, so why put it here?
2063 Move code to initialize and search %load-path from ice-9 to C
2064 code, so we can use the load-path to find the ice-9 boot code;
2065 this makes it easier to run Guile without installing it. See
2066 corresponding changes in guile/Makefile.in.
2067 * feature.c: Move stuff concerned with the load path to load.c.
2068 (scm_compiled_library_path): Deleted.
2069 Don't #include libpath.h here.
2070 * feature.h: Don't mention scm_compiled_library_path.
2071 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
2072 <sys/stat.h>, and <unistd.h> (if present).
2073 (R_OK): #define if the system hasn't deigned to.
2074 (scm_loc_load_path): New variable.
2075 (scm_init_load_path, scm_sys_search_load_path,
2076 scm_sys_try_load_path): New functions.
2077 (scm_init_load): Initialize scm_loc_load_path to point to the
2078 value cell of the Scheme %load-path variable.
2079 * load.h: Add declarations for scm_sys_search_load_path,
2080 scm_sys_try_load_path.
2081 * init.c: Call scm_init_load_path.
2082 * Makefile.in (feature.o, load.o): Dependencies updated.
2084 * load.c, load.h: Rewrite using PROTO macro.
2086 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2088 * gc.c (scm_cellp): New function: C predicate to determine if an
2089 SCM value can be regarded as a pointer to a cell on the heap.
2091 * gc.h: Added declaration of scm_cellp.
2093 * gdb_interface.h: New file: The GDB interface header from the GDB
2096 * gdbint.c: New file: GDB interface.
2098 * gdbint.h: New file: GDB interface.
2100 * libguile.h: Added #include <libguile/gdbint.h>.
2102 * init.c (scm_boot_guile): Added scm_init_gdbint.
2104 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
2105 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
2106 found if object files and source are kept separate).
2108 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
2110 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
2112 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
2114 * configure.in: Don't substitute the values of TCL_SRC_DIR and
2115 TK_SRC_DIR; they're not relevant any more.
2117 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
2118 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
2120 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
2122 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
2123 search path, so we can find the <libguile/MUMBLE.h> headers.
2125 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
2127 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
2128 implicit in the .c.o rule.
2129 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
2132 Put the library path in a header file, instead of passing it on
2133 the command line in every compilation.
2134 * Makefile.in (libpath.h): New target.
2135 (feature.o): Depend on libpath.h.
2136 (clean): Delete libpath.h.
2137 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
2138 * feature.c: ... #include "libpath.h" here.
2139 * .cvsignore: Ignore libpath.h.
2141 Don't install the unwashed masses of Guile header files in the
2142 main #include path; put most of them in a subdirectory called
2143 'libguile'. This avoids naming conflicts between Guile header
2144 files and system header files (of which there were a few).
2145 * Makefile.in (pkgincludedir): Deleted.
2146 (innerincludedir): New variable; this and $(includedir) are enough.
2147 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
2148 (installed_h_files): Divide this up. Now this variable lists
2149 those header files which should go into $(includedir) (i.e. appear
2150 directly in the #include path), and ...
2151 (inner_h_files): ... this new variable says which files appear in
2152 a subdirectory, and are referred to as <libguile/mumble.h>.
2153 (h_files): List them both.
2154 (install): Create innerincludedir, not pkgincludedir. Put
2155 the installed_h_files and inner_h_files in their proper places.
2156 (uninstall): Corresponding changes.
2157 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
2158 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
2159 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
2160 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
2161 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
2162 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
2163 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
2164 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
2165 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
2166 vports.h, weaks.h: Find __scm.h in its new location.
2167 * __scm.h: Find scmconfig.h and tags.h in their new locations
2168 (they're both "inner" files).
2170 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
2172 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
2174 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2176 * posix.c: Doc fixes.
2178 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
2180 * socket.c: Don't include a prototype for inet_aton; just use a
2181 K&R style declaration, to avoid warnings but minimize the chance
2182 of conflicts with the system.
2184 On NextStep, <utime.h> doesn't define struct utime, unless we
2185 #define _POSIX_SOURCE before #including it.
2186 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
2187 * acconfig.h: New comment text for above CPP symbol.
2188 * configure.in: Call it.
2189 * posix.c: #define _POSIX_SOURCE if it seems necessary.
2191 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
2193 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
2194 testing for __EMX__.
2196 * posix.c: #include <libc.h>, if it exists.
2198 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
2199 don't even know if the latter exists.
2201 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
2202 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
2203 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
2205 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
2207 (scm_init_posix): Use them when initializing the Scheme constants
2210 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2212 * Makefile.in (libdir, includedir, bindir): Use the
2213 autoconf-supplied values, instead of deriving them ourselves.
2214 (pkgincludedir, datadir, pkgdatadir): New variables.
2215 (install, uninstall): Put the header files in a special
2216 subdirectory, not in the main search path.
2218 * Makefile.in (ALL_CFLAGS): Provide the proper value for
2219 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
2221 * Makefile.in (IMPLPATH): Deleted; never used.
2223 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
2224 on the Tcl/Tk source any more.
2225 (INCLUDE_CFLAGS): Remove references to the above.
2227 * Makefile.in (version.o): Corrected dependencies.
2229 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
2231 * libguile.h: #include "version.h"
2233 * init.c (scm_boot_guile): Call scm_init_version.
2234 * gscm.c (gscm_run_scm): Call scm_init_version.
2236 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
2237 GUILE_VERSION): AC_DEFINE these.
2238 (acconfig.h): #undef the above symbols.
2240 * Makefile.in (libobjs): Add version.o.
2241 (installed_h_files): Add version.h.
2242 (c_files): Add version.c.
2243 (gen_c_files): Add version.x.
2244 (version.o): New rule.
2245 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
2246 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

2260 * version.c: New file.
2262 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2264 * symbols.c (scm_strhash): scm_downcase is now a function, not an
2265 array; use it appropriately. Since GCC is quite happy to
2266 subscript functions, it never warned us about this; we should use
2267 -Wpointer-arith in the future. I guess we never tested
2270 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2272 * socket.c: Doc and copyright fixes.
2274 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>

2278 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2280 * socket.c: Added declaration of inet_aton to avoid compiler
2281 warning. (Hope this solution is correct.)
2283 * stime.c: Added declaration of ftime. (This is missing in
2286 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
2288 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2290 * Makefile.in (c_files): add strerror.c.
2292 * strerror.c: new file from Emacs' sysdep.c.
2293 maybe configure should also check for sys_errlist.
2295 * configure.in (AC_REPLACE_FUNCS): add strerror.
2297 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2299 * debug.c (scm_init_debug): Added initialization for
2300 scm_evaluator_traps.
2302 * debug.h, debug.c: Various name changes.
2303 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
2304 "debug-options-interface". See commentary in options.c.
2306 * options.h, options.c: Options now have documentation strings.
2307 Also added a long explanatory commentary.
2309 * eval.c, print.h, print.c, read.h, read.c: Modifications to
2312 * gscm.c, init.c, root.c, throw.c: Bug fixes:
2313 last_debug_info_frame is now updated in all cases.
2315 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
2318 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2320 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
2321 Added option STACK_CHECKING.
2323 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
2325 * Makefile.in: Added {debug,options,srcprop}.{h,c}
2327 * __scm.h: Removed symbols for debugging support.
2329 * acconfig.h: Added symbols for debugging support.
2331 * configure.in: Added user option for debugging support.
2332 --enable-debug will include the debugging code into libguile.a.
2334 * continuations.c (scm_make_cont): Enlarged the #if 0 around
2335 scm_relocate_chunk_to_heap.
2337 * debug.c: New file: low-level debugging support. It also
2338 includes support for debugging with gdb. (The extensions to gdb
2339 are written by Per Bothner at Cygnus.)
2341 * debug.h: New file: low-level debugging support.
2343 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
2344 argument pairs. Extensive modifications to the debugging
2345 evaluator. Added "SECTION:" commentaries to clarify what happens
2346 when, during double compilation. Renamed EVALIMP --> EVALIM.
2347 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
2348 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
2349 the beginning of the file. New procedure: scm_unmemocopy.
2350 Added some global state variables needed by the debugging
2351 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
2352 check_entry, check_apply, check_exit, debug_options and
2353 evaluator_traps. New acro: undefine.
2355 * eval.h: Renamed EVAL --> XEVAL.
2357 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
2358 --> scm_make_weak_key_hash_table.
2360 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
2361 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
2363 * libguile.h: Conditionally include debug.h
2365 * objprop.c (scm_object_properties, scm_set_object_properties_x):
2366 scm_object_properties shouldn't return handle. `handle' now gets
2367 initialized in scm_set_object_properties_x. scm_object_properties
2368 doesn't any longer create an entry in scm_object_whash.
2370 * options.c: New file: handling of run time options.
2372 * options.h: New file: handling of run time options.
2374 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
2376 * print.c: New procedure: scm_print_options
2378 * print.h: Defines for print options.
2380 * read.c: New procedure: scm_read_options
2382 * read.h: Defines for reader options.
2384 * root.h: Added scm_source_whash among scm_sys_protects.

2393 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2395 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
2397 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
2399 * libguile.h: #include "objprop.h"; I guess this was forgotten.
2401 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
2402 and should be called by the final client.
2404 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
2406 * gc.h: Use the PROTO macro when declaring functions.
2407 * gc.c: Use the PROTO macro when declaring static functions.
2408 Remove the CPP hair around function definitions.
2410 * gc.c (scm_init_storage): Initialize scm_asyncs.
2412 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
2413 preprocessor symbol; "__scm.h" is where it might get #defined.
2414 * __scm.h: Similar: #include <scmconfig.h> before testing
2417 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
2419 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
2421 * init.c (scm_boot_guile): Add init_func argument; call
2422 (*init_func) instead of calling scm_appinit; it's ucky to
2423 hard-code names for the user's procedures.
2424 * init.h (scm_boot_guile): Adjust declaration.
2426 * __scm.h (PROTO): New macro, for declaring functions with
2429 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
2430 eliminate all the __STDC__ conditionals.
2431 (scm_boot_guile): Add declaration.
2432 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
2433 Remove __STDC__ conditionals around function definitions; the
2434 declarations in init.h will provide the same information, more
2437 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
2438 complain about it in the error message; the error message is
2439 adequate without that note, and there's nothing the user can do
2442 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
2444 * Makefile.in (ancillary): Drop def.sed.
2446 * posix.c (scm_init_posix): Use numeric values, rather than
2447 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
2448 F_OK. The symbols aren't available on some systems, and I'm
2449 pretty sure their values are fixed by common widespread practice.
2450 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
2452 More functions unavailable on some systems.
2453 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
2454 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
2456 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
2457 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
2458 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
2459 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
2460 stub that signals an error as the #else.
2462 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
2464 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
2466 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
2468 * unif.c: include ramap.h.
2470 * read.c (endif): case_insensative_p renamed case_insensitive_p.
2472 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
2474 * ports.c: include sys/ioctl.h.
2476 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
2478 * configure.in: check for sys/ioctl.h.
2480 * ports.c: include <malloc.h> not "malloc.h".
2482 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2484 * fports.c: remove ttyname and tmpnam declarations.
2486 * posix.c: fewer ttyname declarations.
2488 * fports.c: include <string.h> not "string.h".
2490 * init.c, ioext.c: include string.h and unistd.h.
2492 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
2494 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
2495 genio.c, simpos.c, vports.c: include string.h.
2497 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
2499 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
2501 (scm_addr_buffer_size): change type from scm_sizet to int.
2502 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
2503 from scm_sizet to int.
2505 * error.c: include unistd.h.
2507 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
2510 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
2512 * __scm.hd, def.sed: deleted.
2514 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
2516 Changes for NeXT, suggested by Robert Brown.
2517 * configure.in: Call AC_TYPE_MODE_T.
2518 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
2519 NeXT. Put header file list in alphabetical order.
2520 * configure, scmconfig.h.in: Regenerated.
2521 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
2523 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
2526 * acconfig.h: New file, providing documentation for the CPP
2527 symbols defined in configure.in
2528 * acconfig-1.5.h: Removed; superceded by the above.
2530 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
2532 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
2534 * fports.c (scm_open_file): don't return #f, throw error.
2536 * ioext.c (fileno): renamed from %fileno.
2537 (soft-fileno): deleted.
2539 * ports.c (scm_port_revealed): don't need to check for -1 from
2541 (scm_set_port_revealed_x): return unspecified, not #f.
2543 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
2545 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
2547 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
2549 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
2551 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2553 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
2554 This is necessary on Ultrix, and doesn't hurt portability.
2556 * Makefile.in (dist-dir): New target, implementing a new dist system.
2557 (installed_h_files): Put in alphabetical order.
2558 Remove duplicate entries for markers.h and unif.h.
2559 (c_files): Remove duplicate entries for markers.c.
2560 (ancillary): Renamed from anillery; all uses changed. Remove
2561 PLUGIN; it's a directory, and needs special treatment in dist-dir.
2562 Remove all the ../doc/* files; doc/Makefile.in handles that.
2564 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
2566 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
2567 every if must have an else, or else the whole command has a
2568 non-zero exit code whenever the if's condition is false.
2570 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
2572 * posix.c: include string.h.
2574 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2576 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
2579 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
2580 Remove leading % from scheme names.
2581 Do not return error values, call SCM_SYSERROR or similar.
2583 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
2585 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
2587 * struct.c (scm_init_struct): new file.
2589 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
2591 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
2592 (scm_list_head): added list-head for rapidly chopping argument
2593 lists off of longer lists (and similar).

2597 * objprop.c (scm_object_property): assq the cdr of the whash
2598 handle for obj, not the handle itself.
2600 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
2602 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
2603 weak hash tables last of all marking to avoid an obscure gc bug.
2604 WARNING: circular lists stored in a weak hash table will hose us.
2606 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
2608 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
2609 new functions similar to scm_substring_move_left_x and
2610 scm_substring_move_right_x.
2612 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
2614 * init.c (scm_boot_guile): prevent gc with scm_block_gc not

2619 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
2621 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
2623 * strports.c (scm_strprint_obj): convenience function. C for
2624 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
2626 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
2627 removed to a separate library
2629 * init.c (scm_boot_guile): copied from guile-tcl.c.
2630 Initialization specific to tcl interpreters removed.
2632 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
2634 * ports.c (scm_ports_prehistory): size malloced here doesn't
2635 matter so long as it is non-0 (got rid of "* 4").
2637 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
2639 * gscm.h: gscm_mkarray eliminated (presumably was not being used
2640 since its definition was bogus).
2642 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
2644 * mallocs.[ch]: back again (for rx at least).
2646 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
2648 * ports.c: removed functions relating to the mapping between ports
2649 and descriptors. (That stuff is unix-specific and should be collected
2650 in a separate library).
2652 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
2653 (Tom Mckay@avanticorp.com)
2655 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
2657 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
2658 handled correctly (SCM_FREEP was applied to them) -- test for
2659 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
2660 being overwritten with #f. (brown@grettir.bibliotech.com)
2662 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
2664 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs

2667 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
2669 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak

2674 * list.c (scm_last_pair): map '()=>'()
2676 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>

2679 Generalized assoc and hash-table functions.
2680 Factored pairs.c into multiple files.
2682 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
2684 * gscm.c (gscm_run_scm): got rid of objprop.
2686 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>

2692 NOTE: don't use a alist here.
2693 (scm_set_procedure_properties_x): fix type checking throughout this file.
2695 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.

2703 * vports.c (scm_make_soft_port): allocate a port table entry
2704 (possibly triggering gc) before setting the tag of the corresponding
2707 * pairs.c (scm_delq_x): never throw an error.
2709 * vectors.c (scm_make_vector): made the default vector fill argument
2710 into '() (much more useful than the previous value, "#unspecified")
2712 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
2714 * ports.c (scm_add_to_port_table): Added fields
2715 to port table entries: file_name, line_num, col.
2716 Update these in open_file, gen_getc and gen_ungetc.
2717 Added procedures to access those fields.
2719 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
2721 * procs.c (scm_make_subr_opt): new entry point for making

2730 * numbers.c (scm_exact_p): This function no longer
2731 implements "integer?".

2735 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
2736 (scm_gc_stats): return an assoc of useful data. Replaces "room"
2737 and the stats reporting formerlly built into repl.

2740 GC statistics keeping moved to gc.c.
2741 Other statistics keeping can be done from Scheme.
2742 REPLS are now written in Scheme.

2751 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
2753 * feature.c (scm_compiled_library_path): moved here from repl.c.
2754 This file is for stuff relating specifically to Scheme libraries
2757 * eval.c (scm_m_define): don't give warning about redefinition, don't
2760 NOTE: this should throw a resumable exception with parameters --
2761 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
2763 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
2765 * error.c: scm_warn eliminated.

2777 between the call to procedurep and use.
2779 * error.c (scm_everr):
2781 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
2784 * strports.c: don't reveal the port's string to the caller
2785 because it changes size.
2787 (stputc stwrite): check/change the strings length with interrupts
2790 * objprop.c (scm_set_object_property_x &c): use the generic
2791 hashing functions and be threadsafe.
2793 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
2794 (per suggestion jaffer@gnu.ai.mit.edu).
2796 * mbstrings.c (scm_multi_byte_string): guard against argument list
2799 * strings.c (scm_make_string): loop cleanup
2801 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer

2815 functions. hash, hashq, hashv, hashx.
2817 * tags.h: made wvect an option bit of vector.

2821 * symbols.c: made the basic symbol table operations atomic.
2823 * root.c &c.: collected stack-specific global state.

2827 initialization to fix a race condition.
2829 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
2830 object, not in a global.
2831 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)

2848 * async.c: New support for interrupt handlers.
2850 Thu Feb 15 11:39:09 1996 Tom Lord <lord@beehive>
2852 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
2853 set the multi_byte flag correctly in symbols. This is wrong.
2854 intern_obbary_soft and msymbolize should take an extra parameter.
2855 Also, weird multibyte symbols don't print correctly.
2856 The weird symbol syntax is also a bit bogus (emacs doesn't quite
2859 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
2861 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
2862 use the system symhash. == #t means create an uninterned symbol.
2864 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
2866 * strings.c (scm_make_shared_substring): build'em.
2867 It might better to keep a table of these and use one
2868 less cons-pair per shared-substring.
2870 Tue Feb 6 17:45:21 1996 Tom Lord <lord@beehive>
2872 * strings.c (scm_string_shared_substring): create shared

2929 (kawai@sail.t.u-tokyo.ac.jp)
2931 * gscm.c (gscm_set_procedure_properties_x): parameter "new" => "new_val"
2932 for C++. (Seth Alves <alves@gryphon.com>)
2934 (gscm_cstr): uses an uninitialized local variable causing
2935 segv. (kawai@sail.t.u-tokyo.ac.jp)
2938 * lvectors.c (scm_get_lvector_hook):
2939 In guile-ii, the lvector code was broken. It was fixed in guile-iii.
2940 It seems to me like if it is broken again in guile-iv...Here is a patch.

2942 (From: Mikael Djurfeldt <mdj@nada.kth.se>)
2945 * gscm.c (gscm_sys_default_verbosity):
2946 incorrectly declared for non-__STDC__
2947 (Tom_Mckay@avanticorp.com)
2949 * ports.c (scm_setfileno): Tweak the macro a bit
2950 to make it easier to port to systems that use
2951 more than a single structure field to hold a descriptor.
2953 * debug.c (change_mode): Avoid GNUCism "int foo[n];"
2954 Give a warning, not an error, for unrecognized modes.
2956 * eval.c (SCM_CEVAL):
2957 static char scm_s_for_each[];
2958 static char scm_s_map[];
2961 * strings.c (scm_string_p):
2962 static char s_string[];
2965 * struct.c (scm_sys_struct_set_x):
2966 static char s_sys_make_struct[];
2967 static char s_sys_struct_ref[];
2968 static char s_sys_struct_set_x[];
2969 Rearrange code to eliminate those forward decls for the sake of
2972 * variable.c (make_vcell_variable): static char s_make_variable[];
2975 * fports.c (scm_port_mode):
2976 chars modes[3] = "";
2980 (Tom_Mckay@avanticorp.com)
2983 * pairs.c (scm_set_cdr_x): non-__STDC__ declaration of
2984 scm_cons2(), scm_acons(), and scm_set_cdr_x() missing semicolon
2985 (Tom_Mckay@avanticorp.com)
2987 * numbers.c (scm_num_eq_p): Non-__STDC__ declaration of
2988 scm_num_eq_p() was scm_equal_p().
2989 (Tom_Mckay@avanticorp.com)
2991 * symbols.c (msymbolize): "CHARS(X) = " => "SETCHARS..."
2992 (Tom_Mckay@avanticorp.com)
2994 Fri Jan 26 14:03:01 1996 Tom Lord <lord@beehive>
2996 * weaks.c (scm_make_weak_vector): "VELTS(X) =" => "SETVELTS..."
2997 (Tom_Mckay@avanticorp.com)

3003 * eval.c (SCM_APPLY): variables "debug_info" -> dbg_info.
3004 Works around a compiler bug on some machines. (Tom_Mckay@avanticorp.com)
3006 * _scm.h (CxR functions): #define CxR SCM_CxR => #define CxR(X) SCM_CxR(X)
3007 Works around a compiler bug on some machines. (Tom_Mckay@avanticorp.com)
3009 * lvectors.c (scm_lvector_set_x): avoid VELTS (VELTS (...)[..]) which
3010 can turn into an obscure gc bug.
3012 * chars.c (scm_char_p): fixed PROC call.
3014 * gscm.h (gscm_vset): use scm_vector_set_x not (the missing)
3017 Tue Jan 23 13:29:40 1996 Tom Lord <lord@beehive>
3019 * elisp.c (new file): dynamic scoping and other bits for
3020 elisp. Don't use this yet unless you specificly want to
3021 hack on elisp emulation.
3023 * dynwind.c (scm_dowinds): When entering or leaving a dynamic
3024 scope created by scm_with_dynamic_bindings_operation_x, swap
3025 the bindings of that scope with the corresponding globals.
3027 * continuations.c (scm_make_cont): when a continuation is captured,
3028 relocate the continuation stack chunks registered on the wind chain
3031 Sun Jan 21 19:31:17 1996 Tom Lord <lord@beehive>
3033 * eval.c (SCM_CEVAL): if the function position evaluates
3034 to a macro, process it accordingly. (Previously, macros were
3035 handled only if the function position was a symbol naming a
3036 variable bound to a macro).
3038 Sat Jan 20 23:21:37 1996 Tom Lord <lord@beehive>
3040 * eval.c (scm_m_set): allow multi-variable set! like
3043 Wed Dec 6 02:40:49 1995 Tom Lord <lord@beehive>
3045 * ports.h fports.c vports.c marksweep.c gc.c strports.c: moved the
3046 STREAM of ports into the port table and replaced it with a
3049 * repl.c (iprin1): added tc7_mb_string -- same as tc7_string.
3051 * marksweep.c (scm_gc_mark): added tc7_mb_string -- same as tc7_string.
3053 * mbstrings.c (new file): functions on multi-byte strings.
3055 * tags.h (scm_typ7_string, scm_typ7_mb_string): added a tag
3056 for multi-byte strings. Moved the string tag.
3058 * chars.h chars.c repl.c (many functions): made scm_upcase and
3059 scm_downcase functions that are safe for extended character sets.
3061 Changed the range of integer->char.
3063 Changed the type of SCM_ICHR.
3065 Tue May 16 17:49:58 1995 Mikael Djurfeldt <mdj@sanscalc.nada.kth.se>

3072 * guile.c (gscm_is_gscm_type): New function. (Without this how will we
3073 know that it's safe to pass an object to gscm_get_type?)
3074 (gscm_get_type): Fix tyop in error message.
3076 * variable.c (scm_variable_ref): fixed assertion test.
3077 (Robert STRANDH <strandh@labri.u-bordeaux.fr>)
3079 * gscm.h: fixed several prototypes, notably gscm_vref.
3080 Add gscm_is_eq and temporarily commented out gscm_eq (see
3081 the note in gscm.h near gscm_eq if this change effects your
3083 (Reported by Mark Galassi <rosalia@sstcx1.lanl.gov>)
3085 * pairs.c (scm_obj_length): see next entry.
3087 * gscm.h (gscm_obj_length): A way to get an integer
3088 length for lists, strings, symbols (treated as strings),
3089 and vectors. Returns -1 on error.

3092 (William Gribble <grib@arlut.utexas.edu>)
3094 * Makefile.in (X_CFLAGS): defined.
3095 (William Gribble <grib@arlut.utexas.edu>)
3097 * gscm.h (gscm_2_double): provided now
