1 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
4 Scheme-level name `array-map' and renamed `serial-array-map' to
7 * backtrace.c: Introduced exception handlers which now enclose
8 `display-error' and `display-backtrace' so that error reporting
9 won't get into infinite loops if an error occurs during displaying
10 of the error. This can very easily happen with user supplied
11 print call-back routines.
13 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
15 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
16 the names `serial-array-map' and `array-map' should be removed.)
18 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
20 * init.c (scm_boot_guile_1): Added scm_init_objects ().
21 Added #include "objects.h"
23 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
24 Add #include "feature.h".
26 * Makefile.am (libguile_la_SOURCES): Added objects.c.
27 (modinclude_HEADERS): Added objects.h.
29 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
30 This test is needed at many places in the code and should be
31 abstracted. (Motivated by the need of this test in libguiletk.)
33 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
34 (scm_eval_string), load.c (scm_primitive_load,
35 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
38 * eval.c (scm_init_eval): Add feature `delay'.
40 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
44 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
46 * list.h (SCM_LISTn): New macros. Make list creation in C code
47 prettier. The idea comes from STk.
49 * sequences.h, sequences.c, append.h, append.c: Removed. These
50 files implemented non-R4RS operations which would encourage
51 non-portable programming style and less easy-to-read code.
53 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
56 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
57 sequences.h, #include append.h.
59 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
62 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
64 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
66 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
68 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
70 * eval.c: Added #include "objects.h"
72 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
75 * smob.c (scm_smob_prehistory): Create two objectsmobs with
76 adjacent smob numbers.
78 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
80 * procprop.h: Added declaration of scm_i_inner_name.
82 * gsubr.c: New global symbol scm_i_inner_name.
84 * debug.c (scm_procedure_name): Try procedure property
85 `inner-name' if `name' fails.
87 * print.c (scm_iprin1): Use scm_macro_name.
89 * eval.c (scm_m_define): Give names to macros as well; Only the
90 first top-level definition gives a procedure/macro a name.
91 Otherwise confusing names can turn up in backtraces.
92 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
93 `name'; Give names to macros as well.
95 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
96 (scm_macro_transformer): Use SCM_CLOSUREP instead of
99 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
101 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
103 (prinmacro): Removed. The code has been moved/merged into print.c
104 in order to decrease code redundancy. We want macros to print in
105 a way equivalent to procedures, and it would be silly to duplicate
106 the required code. (We don't want to maintain two places.)
107 (macrosmob): Print field is now a NULL pointer.
109 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
110 scm_macro_transformer): New prototypes.
111 (scm_tc16_macro): Declared.
113 * * print.c (scm_iprin1): Added code for printing of macros. Macros
114 are now printed in a way equivalent to procedures.
116 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
118 * procs.h (scm_closure_p): Added declaration.
120 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
122 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
123 Shouldn't pass "heap" as the subr name.
125 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
127 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
128 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
129 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
130 gh_equal_p): Use SCM_NFALSEP, instead of testing against
131 SCM_BOOL_T. Any non-false value is true.
133 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
135 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
136 scm_gensym): Added prototypes.
138 * symbols.c (scm_gensym): New function. This will speed up
139 certain types of applications (such as macro systems) which
140 generate lots of symbols.
142 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
144 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
146 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
148 * unif.c (scm_shap2ra): tighten the checking of the array dimension
149 specifier, since (2) or (2 . 3) would cause SEGV.
150 (scm_transpose_array): more argument checking fixes.
152 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
154 * Makefile.in: Regenerated.
156 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
158 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
160 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
162 * error.c, error.h (scm_error_callback): Removed (see NEWS).
164 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
166 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
167 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
170 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
171 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
172 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
173 scm_array_p, scm_array_rank, scm_array_dimensions,
174 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
175 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
176 scm_array_prototype): Added case scm_tc7_wvect.
178 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
180 * errno.h: prototype for scm_strerror.
181 * error.c (scm_strerror): new procedure.
183 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
185 * list.c (scm_list_append_x): Allow non-pair as last argument.
186 This is consistent with the R4RS append and is probably the
187 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
189 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
191 * stime.h: prototype for scm_times.
192 * stime.c (scm_times): new procedure.
193 * ioext.c (scm_fseek): if the first argument is a file descriptor
195 (scm_ftell): if the first argument is a file descriptor call lseek
197 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
198 * filesys.c (scm_chmod): if the first argument is a file descriptor,
200 (scm_chown): if the first argument is a port or file descriptor,
202 (scm_truncate_file): new procedure.
203 Add DEFER/ALLOW INTS to a few other procedures.
204 (scm_fsync): new procedure.
205 (scm_open_fdes): new procedure.
206 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
208 (scm_fcntl): the first argument can now be a file descriptor. The
209 third argument is now optional.
211 * posix.c (scm_execl, scm_execlp): make the filename argument
212 compulsory, since omitting it causes SEGV.
213 (scm_sync): return unspecified instead of #f.
214 (scm_execle): new procedure.
215 (environ_list_to_c): new procedure.
216 (scm_environ): use environ_list_to_c. disable interrupts.
217 (scm_convert_exec_args): take pos and subr arguments and
218 improve error checking.
220 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
222 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
223 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
224 argument to SCM_ASSERT. Furthermore, the name of the function
225 should be passed as first argument when signalling
226 SCM_WNA. (Thanks to Thomas Morgan)
228 * gsubr.c (scm_gsubr_apply): From Radey Shouman
229 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
230 dispatches on the number of actual args has a default case
231 reporting an internal error. This is a vestige from a version
232 that mallocated a SCM vector to hold the arguments. In the
233 current version this check is too late: if it ever happens we will
234 have already overstepped the bounds of the array.
236 Also, the patch [...] adds a check for too many actual arguments."
238 mdj: Removed check for "internal programming error".
240 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
242 * gh_io.c (gh_write): New function.
244 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
245 throw.c (scm_internal_stack_catch): New sibling to the other catch
246 functions. Code moved from gh_eval.c.
247 throw.h: Added header.
248 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
249 scm_internal_stack_catch.
251 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
253 * ioext.h: fix up prototypes.
254 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
255 Scheme name is now dup->fdes.
256 (scm_dup_to_fdes): make the second argument optional and
257 fold in the functionality of scm_primitive_dup.
258 (scm_primitive_dup): deleted.
260 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
262 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
263 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
264 ultrix are defined. Use setvbuf instead of setbuf.
265 (scm_setvbuf): new procedure.
266 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
267 (scm_setfileno): moved from ioext.c.
268 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
269 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
271 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>

278 * print.c (scm_iprin1): Enter printed structures into the print
279 state as nested data while they are printed.
280 (print_state_fluid, print_state_fluid_num): New variables.
281 (scm_init_print): Initialize them.
282 (scm_iprin): If print_state_fluid carries a print_state, use that
283 instead of creating a new one.
284 (scm_printer_apply, apply_stub, struct apply_data): New
285 definitions to help with calling printer functions written in
287 * print.h (scm_printer_apply): New prototype.
289 * struct.c (scm_print_struct): Use scm_printer_apply to call the
290 user defined struct printer.

296 scm_swap_fluids, scm_swap_fluids_reverse): New functions.
298 Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
300 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
301 SCM_ASSERT: arg comes before pos.
303 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
305 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
306 to a list of length zero correctly.
308 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
310 Supply an `fgets' method for port objects to do fast line i/o.

312 * genio.c (scm_gen_read_line): New function.
313 * fports.c (scm_fgets): New function.
314 (scm_fptob, scm_pipob): Add scm_fgets method.

324 * ioext.h: removed scm_duplicate_port prototype.
326 * ioext.c (scm_primitive_dup2): return the new file descriptor
327 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
329 (scm_fdopen): bug fix: don't try to make port unbuffered until its
331 (scm_duplicate_port): deleted, there's now an implementation in
333 (scm_primitive_dup2): do nothing if newfd == oldfd.
335 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
337 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
340 * ioext.h: new prototypes.
341 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
343 * fluids.c (next_fluid_num): don't do
344 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
346 * ports.h: prototypes too.
347 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
349 * fports.h: prototype too.
350 * fports.c (scm_evict_ports): moved from ioext.c.
352 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
354 * ports.c (scm_close_port): return a boolean instead of unspecified.
355 throw an error if an error other than EBADF occurs.
357 * filesys.h: scm_close prototype.
358 * filesys.c (scm_close): new procedure, can close file descriptors
359 and ports (scsh compatible).
361 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
364 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
366 * fluids.c, fluid.h: New files.

377 (scm_make_root): Call scm_copy_fluids to make fluid bindings
378 unique for the new root when it has a parent.
380 * smob.h: Include "libguile/print.h" to make scm_print_state
383 * dynl.c (free_dynl_obj): New function to free the dynamic object
384 data. (dynl_smob): Use it.
385 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
386 the dynamic object data below the linking of the object to avoid
387 memory leak when the linking code throws an error. Now the code
388 leaks a whole dynamically linked library when must_malloc throws,
389 but that should be much less likely.
391 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
393 Changes to compile under gnu-win32, from Marcus Daniels:

395 (scm_localtime): Change SCM_EOF to SCM_EOL.
396 (scm_mktime): Likewise.
397 * socket.c: Don't include sys/un.h unless autoconf tells
398 us Unix domain sockets are available.
399 (scm_fill_sockaddr): Ignore Unix domain code.
400 (scm_addr_vector): Likewise.
401 (scm_init_addr_buffer): Likewise.

403 found during autoconf.
404 * simpos.c (SYSTNAME): Treat cygwin like Unix.
405 * scmsigs.c (scm_pause): Don't include unless pause was found
407 * posix.c (scm_getgroups): Don't include unless support function
408 was found during autoconf (in this case, getgroups).
409 (scm_setpwent): For setpwent.
410 (scm_setegid): For setegid.
411 * net_db.c (scm_inet_netof): Don't include unless support
412 function was found during autoconf (in this case, inet_netof).
413 (scm_lnaof): For inet_lnaof.

426 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
427 scm_misc_error, not SCM_EOF.
429 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
430 arguments for formatting the error message, not SCM_BOOL_F. I
431 think this is left over from the (eq? '() #f) days.
433 * read.c (recsexpr): Give this a dummy definition if
434 DEBUG_EXTENSIONS isn't #defined.
436 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
438 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
441 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>

446 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
448 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
449 alloca.lo will be included in @LIBLOBJS@. Something better than
450 this should be possible.
451 * Makefile.in: Regenerated.
453 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
455 * simpos.h: prototype for scm_primitive_exit.
456 * simpos.c (scm_primitive_exit): new procedure, terminates the
457 process without unwinding the stack.
459 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
461 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
462 argument and logior its components together, so the user doesn't
463 have to do this explicitly. Also, if regexp/basic is supplied, then
464 turn off REG_EXTENDED.
465 (scm_init_regex_posix): New regexp/basic symbol.
466 (REG_BASIC): #define this if it is not already present.
468 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

476 Tue Jun 24 00:29:07 1997 Jim Blandy <jimb@floss.red-bean.com>
478 * script.c (scm_compile_shell_switches): Add 1997 to copyright
479 years in usage message.
481 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
482 * Makefile.in: Regenerated.
484 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
485 flag; I don't think we support it.
486 (scm_make_regexp): Make sure the user doesn't pass the
489 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
491 (scm_init_regex_posix): Define constants for the REG_mumble flags;
492 name them according to the SCSH convention: regexp/mumble.
494 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
496 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
498 * Makefile.am (libpath.h): Include the values of all the standard
499 Makefile directory variables. Print a message, but don't print
501 (versiondat.h): Print a message, but don't print all the commands.
502 * load.c: #include "alist.h".
503 (init_build_info): New function.
504 (scm_init_load): Call it.
505 * Makefile.in: Regenerated.
507 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
509 * root.c: Establish a reliable catch-all handler for the new root.
510 After all the Scheme handler function might signal an error too,
511 and we don't want to lose that.
512 (cwdr_inner_body): Renamed from cwdr_body.
513 (cwdr_outer_body): New function, to establish the user's handler,
514 and pass control to cwdr_inner_body.
515 (cwdr): Establish the reliable catch-all handler here, and pass
516 control to cwdr_outer_body.
517 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
518 the user's handler through to cwdr_outer_body.
519 * throw.c (scm_handle_by_message): Move guts into....
520 (handler_message): New static function.
521 (scm_handle_by_message_noexit): New function.
522 * throw.h (scm_handle_by_message_noexit): New prototype.
524 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
525 across this. Only works on GCC. Otherwise, we hope for the best.
526 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
527 the feeling that real thread systems will not need this...
529 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
531 Try to detect when people are using one version of libguile and a
532 different version of ice-9. People have been skewing things and
533 sending in bug reports.
534 * Makefile.am (versiondat.h): New file to generate.
535 * version.c: #include "versiondat.h", to get version info.
536 (scm_libguile_config_stamp): New function.
537 * script.c: #include "version.h".
538 (scm_compile_switches): Call scm_version to get version number.
539 * scmconfig.h.in, Makefile.in: Regenerated.
540 * Makefile.in: Regenerated.
542 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
543 primitive definitions under their Scheme names.
545 * Makefile.am (libguile_la_LDFLAGS): Update library version to
546 1:2. Helps avoid confusion between installed and uninstalled libs.
548 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
551 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
552 backslash from definition; this should be used like: GDB_INTERFACE;
554 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
556 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
557 new port unbuffered until its stream has been set.
559 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
561 * ports.h: new prototype.
562 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
564 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
566 Make things compile neatly under Sun's C compiler.
567 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
568 * extchrs.c (xmbtowc): Make the second arg a normal char, not
569 unsigned, because that's what the ANSI function takes.
570 * extchrs.h (xmbtowc): Corresponding change to prototype.
571 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
573 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
574 argument plain char *.
575 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
577 * tag.c (scm_tag): Remove unreachable statement.
578 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
579 top of the word, it should be unsigned.
581 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
582 is defined, to avoid warnings; it's only used in the
583 conflict-checking code. Which might go away anyway.
584 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
585 conditionals; put the label definition in an #if too, to stifle
588 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
589 ChangeLog-threads in the distribution.
590 * Makefile.in: Regenerated.
592 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
594 * guile-snarf.in: Changed regexp to support CPPs that insert
595 whitespace between lexical tokens (which munges the `%%%' snarf
598 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
600 * load.c (scm_init_load_path): Append $(datadir)/guile to
601 %load-path, so modules do not have to be installed in Guile's
602 current version directory.
604 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
606 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
607 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
608 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
609 call the sysdep functions with deferred ints.
610 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
611 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
612 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
615 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
618 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
620 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
622 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
624 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
627 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
629 * eval.c (scm_lookupcar1): New procedure to cope with a race
630 condition during lookup (when using threads).
631 (scm_lookupcar): Implement in terms of scm_lookupcar1.
632 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
635 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
637 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
638 supplied. (Change from Tim Pierce.)
640 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
642 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
643 23:47:01 1997" changelog: Slots are now initialized with `#f' by
644 default and not `()'. `#f' is the canonical non-value in Scheme,
647 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
649 * struct.c (struct_printer): New variable that holds a handle on
650 the Scheme variable *struct-printer*. This variable can be set by
651 Scheme code to override the printing of structures.
652 (scm_print_struct): If struct_printer is set, call it. If it is
653 not set, or returns #f, print the structure in the old fashion.
654 Include "eval.h" for scm_apply.
656 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
658 * struct.c (scm_struct_ref, scm_struct_set_x): Use
659 scm_struct_i_n_words to get the number of fields, not
660 -scm_struct_n_extra_words.
662 On the route to fancier struct printing:
663 * struct.c (scm_print_struct): New function to print a structure.
664 Include "genio.h" to support it. This function doesn't do
665 anything interesting right now, but I think it should be here
667 * struct.h: Include "print.h" and add prototype for
669 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
670 print structures ourself.
672 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
674 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
675 before applying the handler in case it doesn't return.
677 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
679 * scmsigs.h, async.h: updated.
681 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
684 * posix.c (scm_uname): interpret only negative values as an error.
685 Solaris normally returns a positive value.
687 * script.c (scm_compile_shell_switches): if we are not going into
688 an interactive repl, set scm_mask_ints to zero so that asyncs can
691 * simpos.c (scm_system): don't ignore/unignore signals around
694 * posix.c (scm_open_pipe): don't ignore/unignore signals around
697 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
698 done in boot-9.scm instead.
700 * scmsigs.c, async.c: Major rewriting of signal handling code.
701 (scm_sigaction): new procedure.
702 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
704 (scm_raise): return unspecified, throw error on failure.
706 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
708 * regex-posix.c (scm_init_regex_posix): Register the "regex"
709 feature, to help boot-9.scm decide whether to import the regex
712 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
714 * eval.c: Include scmconfig.h at the beginning of the file so that
715 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
718 * regex-posix.c: #include "_scm.h" before conditionally #including
719 <regex.h>; the former defines HAVE_REGCOMP.
721 * regex-posix.c: #include <regex.h> conditionally, so the file is
722 CPP'able (for dependency scanning) even on systems that don't have
725 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
727 Add new R4RS-compliant syntax for keywords.
728 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
729 regardless of the setting of the `keywords' read option.
730 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
731 can be re-read no matter what the setting of the `keywords' read
734 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
736 Add support for POSIX regular expressions.
738 * regex-posix.c, regex-posix.h: New files. (Some code
739 is taken liberally from rx/rgx.c in the old Guile dist.)
741 * init.c: Include regex-posix.h.
742 (scm_boot_guile_1): Call scm_init_regex_posix.
744 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
745 Add regex-posix.[ch] sources.
746 * Makefile.in: Regenerated.
748 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
749 to do this automatically? It didn't for me, bleh.)
751 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
753 * fports.c (print_pipe_port): New function.
754 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
755 latter doesn't even take the right arguments.
757 * Makefile.am: Increment shared lib revision number. I think
758 sometimes the uninstalled Guile finds the installed shared lib;
759 Gord says doing this might help. As things turned out, I can't
761 * Makefile.in: Regenerated.
763 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
764 passing it as the closure argument to scm_boot_guile. (Bill
767 * ports.c (print_void_port, putc_void_port, puts_void_port,
768 write_void_port, flush_void_port, getc_void_port, close_void_port,
769 noop0): Use ANSI prototypes instead of K&R declarations, so the
770 initialization of void_port_ptob gets aggressively type-checked.
771 Fix arguments of print_void_port and write_void_port. (Bill

805 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
807 * script.c (scm_find_executable): Use prototype-style definition
808 here; apparently it's not quite right to have const in a prototype
809 and then use a K&R declaration. I wonder if stuff like this will
810 go away if we compile with -Wrequire-prototypes, or whatever that
811 is... (Bernard URBAN)
813 * scmhob.h: New text from Bernard URBAN.
815 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
817 * script.c: Don't #define const on hpux. Configure takes care of
818 this. (Thanks to Larry Schwimmer.)
820 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
821 decide whether to #include <unistd.h>, instead of listing a bunch
822 of systems. Don't #include stdio twice. Removed dyked-out
823 definition of scm_find_impl_file.
825 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
827 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
828 library version info to 1:0.

836 throw.c: Update copyright years; these files have been worked on
837 significantly in 1997, but only had copyright years for 1996.
838 Also, change name of copyright holder on some from Mikael
839 Djurfeldt to Free Software Foundation; he has signed papers
840 assigning the changes to the FSF.
842 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
843 reason not to give the user the option.
845 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
846 Return #f on end-of-file when scanning table (i.e. when called
847 with no arguments). Try to catch errors, when we can.
848 * posix.c (scm_getgrgid, scm_getpwuid): Same.
850 * script.h (scm_shell_usage, scm_compile_shell_switches): New
851 external declarations. These are useful.
853 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
855 * posix.c: don't include <sys/select.h> or define macros for
856 select, since they were not used in this file.
858 * filesys.c (scm_select): make the fifth parameter microseconds,
859 not milliseconds. let the fourth parameter be either a real value
860 or an integer or #f. The first, second and third arguments can
861 now be vectors: the type of the corresponding return set will be
863 (set_element, get_element): new static procedures.
865 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
867 * strports.c (scm_eval_string): New function.
868 (scm_eval_0str): Trivially re-implemented in terms of
870 * strports.h (scm_eval_string): New extern decl.
872 * net_db.c (h_errno): Add extern decl for this.
874 * fports.c (local_pclose): New function.
875 (scm_pipob): Use it in the initializer here.
878 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
879 Use a meaningful error message when signalling an error. For
880 this, scm_gethost must check h_errno rather than errno.
882 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
884 * Makefile.in: Regenerated, using automake-1.1p.
886 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
888 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
891 * script.c (scm_compile_shell_switches): don't append (quit) if
893 (scm_shell): call scm_exit_status and exit on the result of the
896 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
898 Ensure that shared substrings are handled properly when passed to
899 a system call or other foreign function. Many thanks to Tim
901 * symbols.h (SCM_COERCE_SUBSTR): new macro.
902 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
903 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
904 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

919 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
921 * error.c (scm_error): Add newline to error message.
923 * init.c (scm_init_standard_ports): Doc fix.
925 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
927 * dynl-shl.c: Completely replaced with new code from Bernard
930 * script.c (scm_ice_9_already_loaded): New variable.
931 (scm_compile_shell_switches): Use it.
933 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
935 * filesys.c (scm_input_waiting_p): add missing third argument to
938 * stime.c (scm_localtime): copy the result of localtime before
939 calling gmtime in case they share a buffer.
940 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
943 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
945 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
947 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
949 * Makefile.am (check-local): New target, which causes 'make check'
950 to run gh_test_c and gh_test_repl, with some trivial input.
951 * Makefile.in: Rgnrtd.
953 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
955 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
958 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
960 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
961 sure how this was supposed to work.
962 (scm_async_click): don't send SCM_TICK_SIGNAL.
963 (scm_init_async): don't initialize %tick-thunk.
965 * the following change doesn't affect the Scheme interface:
966 gc-thunk is called at the end of garbage collection. however it's
967 no longer implemented by pretending it's a signal.
969 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
970 system async corresponding to scm_gc_thunk.
971 * async.h: declare scm_gc_async.
972 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
973 gc-thunk directly, instead of going through a signal handler.
974 (scm_gc_async): new variable, points to the GC system-async.
975 (scm_init_async): save the GC async as scm_gc_async instead
976 of using system_signal_asyncs.
977 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
979 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
981 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
982 Don't screw up if we're interrupted.
983 * Makefile.in: Regeneradet.
985 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
987 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
989 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
990 we're not using AM_INIT_GUILE_MODULE any more.
991 * Makefile.in: Reneregated.
993 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
995 Functions for finding variable bindings, grace à Tim Pierce.
996 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
997 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
999 Get 'make dist' to work again.
1000 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
1001 * Makefile.in: Regenerated, like a surry without a fringe on top.
1003 Changes for reduced Guile distribution: one configure script,
1005 * configure.in, configure: Removed.
1006 * acconfig.h, acinclude.m4: Moved to parent directory, where the
1007 real configure script lives.
1008 * Makefile.in, scmconfig.h.in: Regenerated.
1010 * init.c: #include "script.h", to get prototype for script.c's
1013 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
1015 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
1016 scm_must_malloc, not raw malloc.
1018 * script.c (scm_compile_shell_switches): Dyke out debugging output
1021 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1023 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
1025 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
1026 system has them. Hope this is safe. Previously
1027 sys/timeb.h was included if HAVE_FTIME was defined or if
1028 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
1029 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
1031 * ioext.c (scm_setfileno): add missing third argument to
1032 scm_misc_error call.
1034 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
1036 * eq.c (scm_equal_p): Correctly compare strings of different
1037 varieties. (Thanks to Tim Pierce.)
1039 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
1041 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
1042 #! block comment must occur on a line all by itself.
1044 Move most of the guts of shell command processing into libguile,
1045 so guile.c can be very small (and eventuallly auto-generated. (I
1046 mean, generated mechanically, not self-generated. Hmm.))
1047 * guile.c, script.c, script.h: New source files.
1048 * init.c (scm_boot_guile_1): Call scm_init_script.
1049 * libguile.h: #include "script.h".
1050 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
1051 targets, for new executable.
1052 (libguile_la_SOURCES): Mention script.c.
1053 (modinclude_HEADERS): Add script.h.
1054 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
1055 not dynamic linking is enabled. This is because we're generating
1056 executables now. Move CY_AC_WITH_THREADS call after those, so the
1057 values of cy_cv_threads_libs captures the libs chosen above.
1058 * Makefile.in, configure, aclocal.m4: Regenerated.
1060 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
1061 We don't maintain this interface any more, and it just confuses
1064 * alloca.c: #include <scmconfig.h>, not <config.h>.
1065 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
1066 it'll get included in disties.
1068 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
1070 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
1071 be distributed, because they confuse people.
1072 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
1074 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
1076 * configure.in: check for presence of gethostent (not present on
1077 OpenBSD by default).
1078 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
1079 * configure, scmconfig.h.in: Regenerated.
1081 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
1083 * backtrace.c (scm_backtrace): Split message string across
1084 newlines properly. GCC is more tolerant of this than other
1087 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
1089 Merge threads directory into libguile.
1090 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
1091 threads.h: New source files.
1092 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
1093 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
1095 (modinclude_HEADERS): Add threads.h, coop-defs.h.
1096 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
1097 coop-threads.c.cygnus, coop-threads.h.cygnus.
1098 * configure.in: If we're using threads, include threads.o in
1100 * _scm.h, libguile.h: threads.h lives in this directory now.
1101 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
1102 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
1103 currently used, but brought along for information's sake.
1104 * ChangeLog-threads: log from old 'threads' directory.
1105 * Makefile.in, configure: Rebuilt.
1107 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
1109 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
1112 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
1114 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
1116 Merge GH interface library into libguile.
1117 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
1118 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
1119 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
1120 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
1122 (EXTRA_libguile_la_SOURCES): ... here.
1123 (pkginclude_HEADERS): Add variable, to get gh.h installed.
1124 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
1125 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
1126 New variables, describing how to build the gh test programs.
1127 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
1128 build the test programs, and we probably should have been linking
1129 libguile.la against them all along, to support AIX shared libs.
1130 Add cflags for threads to CFLAGS; add libs for threads to new
1131 variable THREAD_LIBS, used in Makefile.am.
1132 * ChangeLog-gh: log from old `gh' subdirectory.
1133 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
1135 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
1137 * acconfig.h: Undo change of Apr 9; including the definition of
1138 PACKAGE in the guile headers conflicts with applications' own
1140 * scmconfig.h.in: Regenerated.
1142 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

1149 when PROC is receiving no arguments.
1151 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
1153 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
1154 have S_IFSOCK. This is the case under Ultrix.
1156 * posix.c (scm_status_exit_val, scm_status_exit_val,
1157 scm_status_term_sig, scm_status_stop_sig): Modified to work with
1158 Ultrix versions of WIFSTOPPED, etc., which assume that their
1159 arguments are lvalues (hmm).
1161 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
1163 * eval.c: Doc fixes.
1165 * throw.c: Doc fixes; rearranged.
1167 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
1169 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
1171 * acconfig.h: Added entry for PACKAGE.
1172 * scmconfig.h.in: Regenerated.
1174 Changes to work with automake-1.1n, which has better libtool support.
1175 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
1176 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
1178 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
1180 * Makefile.in: Rebuild.
1182 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1184 * stime.c (scm_mktime): take an optional zone argument.
1185 (scm_localtime): check putenv return value.
1186 (scm_strftime, scm_strptime): moved from posix.c. move #include
1188 stime.h, posix.h: update prototypes.
1189 (bdtime2c, setzone, restorezone): new static procedures.
1190 (scm_mktime, scm_strftime): use them.
1191 (scm_strftime): don't call mktime before strftime. Use
1192 filltime for return value.
1193 (filltime): convert NULL zname to #f.
1194 (scm_strptime): return a count of characters consumed, not
1195 the remaining string.
1197 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1199 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
1200 (scm_mktime): likewise.
1202 Uncomment localtime and mktime.
1204 * configure.in: add AC_STRUCT_TIMEZONE.
1206 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
1208 * stime.c (scm_init_stime): don't define ticks/sec.
1209 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
1210 return value problem and is still portable.)
1212 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
1214 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
1215 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
1216 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
1217 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
1218 cpp_err_symbols.c): Corresponding changes.
1219 * Makefile.in: Regenerated.
1221 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
1223 * posix.c (scm_putenv): don't check HAVE_PUTENV.
1224 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
1225 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
1226 * putenv.c: new file, from sh-utils 1.12.
1228 * posix.c (scm_environ): use malloc in place of scm_must_malloc
1229 since allocation isn't for Scheme objects.
1230 (scm_putenv): copy strings before placing in the environment.
1232 * stime.c (scm_current_time): throw an error if time returns -1,
1233 instead of returning #f.
1234 (scm_get_internal_real_time, scm_get_internal_real_time): use
1235 scm_long2num for return value instead of SCM_MAKINUM.
1237 * stime.h: prototypes updated.
1239 * stime.c (scm_time_in_msec): apparently unused, deleted.
1241 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
1243 * configure.in: check for gettimeofday.
1245 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
1246 which may be more usefully portable than a gettimeofday interface.
1248 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
1250 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
1252 * Makefile.in: Regenerated.
1254 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
1256 * stime.c (filltime): recovered static procedure.
1257 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
1260 * posix.h: add prototype for scm_close_pipe, remove prototypes for
1261 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
1263 * posix.c (scm_mknod): split the mode argument into type and perms
1264 arguments, like the extra fields returned by stat.
1266 * fports.c (scm_pipob): set the close, free and print procedures.
1267 (scm_close_pipe): new procedure.
1269 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
1270 define them in boot-9.scm
1272 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1274 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
1275 wan't defined. Don't include fd.h.
1277 * Previously fd.h was regenerated whenever configure was run,
1278 forcing a couple of files to be recompiled.
1280 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
1281 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
1282 Check for _fileno as well as _file.
1284 * ioext.c: don't fd.h.
1285 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
1288 * Change the stratigy for getting information about errno
1289 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
1290 generating lists of symbols during the build process, which will
1291 not always work, include comprehensive lists in the distribution.
1292 To help keep the lists up to date, the "check_signals" and
1293 "check_errnos" make targets can be used.
1295 * configure.in: don't check for a command to extract errno codes.
1296 * Makefile.am: update file lists, remove errnos.list and errnos.c
1297 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
1298 check_errnos targets.
1299 (CLEANFILES): remove errnos.c and errnos.list, add
1300 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
1301 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
1302 * errnos.default: deleted.
1303 * cpp_signal.c: new file.
1304 * cpp_errno.c: renamed from errnos_get.c.
1305 * cpp_err_symbols, cpp_sig_symbols: new files.
1306 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
1307 * error.c (scm_init_error): #include cpp_err_symbols instead of
1309 * posix.c (scm_init_posix): don't intern signal symbols. #include
1312 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
1314 * strop.c (scm_i_index): allow the lower bound to be equal to the
1315 length of the string, so a null string doesn't always give an error.
1317 * posix.h: new prototypes.
1318 * posix.c (scm_status_exit_val, scm_status_term_sig,
1319 scm_status_stop_sig): new functions, as in scsh. They break down
1320 process status values as returned by waitpid.
1322 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
1324 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
1325 configure doesn't know about it.
1327 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1329 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
1331 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
1332 which defines C variables with global linkage.
1334 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1336 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
1339 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
1341 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
1342 has time to check why this doesn't work well with continuations.
1344 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
1346 * Fix shell syntax error; some shells won't tolerate
1347 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
1349 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
1351 * posix.c (scm_uname): throw an error if uname fails instead
1354 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
1356 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
1359 * async.c (scm_ints_disabled): definition moved from error.c.
1361 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1363 * acconfig.h: Removed PACKAGE.
1365 * scmconfig.h.in: Regenerated.
1367 * snarf.h: g++ says it's non-portable not to specify the first
1368 argument in a varargs declaration. I introduced the first
1369 argument by using preprocessor conditionals.
1371 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
1373 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
1374 (scm_freopen): use RO string macros for filename and modes.
1375 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
1377 * posix.c (scm_getgrgid): simplify conversion of name to C string.
1378 (scm_mknod): use RO string macros for path.
1380 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
1381 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
1383 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
1384 use SCM_ROSTRINGP and SCM_ROCHARS.
1386 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1388 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
1391 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
1392 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
1393 support for byte vectors.
1395 * print.c (scm_iprin1): Limit number of vector elements printed
1396 according to pstate->length.
1398 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
1400 * backtrace.c (scm_display_error_message): don't segv if message
1403 * error.h: prototype for scm_error_scm.
1405 * error.c (scm_error_scm): new procedure, reimplements scm-error
1406 in C and uses scm_error.
1408 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
1410 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
1411 pointer to the Scheme variable read-hash-procedures and intern it
1412 in scm_init_read. Modify scm_read_hash_extend and
1413 scm_get_hash_procedure to use the pointer.
1415 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1417 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
1418 (SCM_KEYWORD_STYLE): defined.
1420 * read.c (scm_read_opts): add a keywords option. This isn't a
1421 boolean option, in case someone wants to add support for DSSSL
1423 Setup scm_keyword_prefix symbol.
1424 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
1426 I've left keyword support disabled by default, since it doesn't
1427 seem to break the module system and it gives R4RS standard behaviour.
1428 It can be reactivated with (read-set! keywords 'prefix).
1430 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1432 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
1433 before constructing arbiter.
1435 * eval.c (scm_m_define): Bugfix: Check that the object is a
1436 closure before setting the procedure property!
1438 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
1440 * ports.c: Removed `ungetc-char-ready?'.
1442 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
1444 * read.c (scm_init_read): intitialise scm_read_hash_procedures
1445 (idea from Mikael: make it a pair so scm_permanent object only
1447 (scm_read_hash_extend): don't call scm_permanent_object.
1448 (ideas from Mikael): if chr is already in the list, replace its
1449 procedure instead of appending it again. If proc is #f, remove
1451 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
1453 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
1455 * gdbint.c (gdb_read): update scm_lreadr usage.
1457 * load.h: update prototypes.
1459 * load.c (scm_primitive_load, scm_read_and_eval_x,
1460 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
1462 * read.h: add prototype for scm_read_hash_extend. Change args for
1465 * read.c (scm_read_hash_procedures): new variable.
1466 (scm_read_hash_extend): new procedure.
1467 (scm_get_hash_procedure): new procedure.
1468 (scm_lreadr): use scm_get_hash_procedure instead of an argument
1469 for extended # processing.
1470 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
1471 scm_read_token): remove case_i, sharp arguments. Change callers.
1473 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
1475 * read.h (SCM_N_READ_OPTIONS): increase to 3.
1476 (SCM_CASE_INSENSITIVE_P): define.
1478 * read.c: add case-insensitive option to scm_read_opts.
1479 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
1480 to determine whether to convert symbol case.
1481 (default_case_i): definition removed.
1482 * read.c (scm_read_token): if case_i, downcase ic before doing
1485 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1487 * configure.in: Added configuration option `guile-debug'.
1488 Configure with --enable-guile-debug if you want a bunch of extra
1489 functions used for debugging when developing Guile.
1491 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
1493 * procs.c (make-cclo): New undocumented debugging procedure: Make
1494 compiled closure with internal procedure PROC and length LENGTH.
1495 Only compiled if GUILE_DEBUG is defined.
1497 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
1499 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
1501 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
1503 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
1504 with 3 or more args internally to the evaluator.
1506 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1508 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
1509 with 3 or more args internally to the evaluator. This is mainly
1510 because we don't want to pass entry and exit points of the
1511 debug support twice, but it also seems to increase the speed of
1512 the evaluator for such calls (e. g. (+ 1 2 3)).
1514 * backtrace.c (scm_display_application): New procedure:
1515 display-application; Set fancy printing parameters individually
1516 for different types of display (backtrace, error, application).
1517 (These should of course be customizable!)
1519 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
1520 clear the CHECK-flags.
1522 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1524 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
1526 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1528 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
1529 from pairs with a GLOC in the car.
1531 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
1532 otherwise `symbol-hash' will behave badly.
1533 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
1534 we get segmentation fault!
1536 * symbols.c: Added #include "weaks.h". New functions:
1537 `builtin-bindings' and `builtin-weak-bindings'. (These will be
1538 moved to an extraneous library when we split libguile.)
1540 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1542 * filesys.c (scm_stat): stat now takes fport arguments too as
1543 documented in the manual.
1545 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1547 * debug.c (scm_single_step): Bugfix: Call continuation with
1548 scm_call_continuation instead of throwing to it.
1550 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1552 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
1553 argument wasn't declared to be optional.
1555 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1557 * stime.c (scm_init_stime): Add feature "current-time".
1559 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
1561 * throw.h: prototype for scm_exit_status.
1562 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
1563 args to derive an exit status. Allows (quit) to work from a
1565 (scm_exit_status): new function.
1568 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1570 * eval.c (scm_deval): Removed some old code.
1571 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
1573 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
1576 * symbols.c (msymbolize): Bugfix: Must initialize property list to
1579 * procs.c: Introduce the existent C function scm_thunk_p at the
1580 Scheme level as well.
1582 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1584 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
1585 used from C to easily lookup the value of a symbol in the current
1588 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1590 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
1591 scm_init_unif in this file. This will also fix a previous problem
1594 * configure.in: Added AM_MAINTAINER_MODE
1596 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1598 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
1601 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1603 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
1604 source files that are not always included in libguile but should
1605 have their dependencies calculated by automake. This variable is
1606 recognized by automake, no further magic is needed.
1607 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
1608 to deal exclusively with *.lo files, as it seems. The *.o files
1609 are built automatically when the corresponding *.lo file gets
1612 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
1614 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
1617 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
1619 * unif.c (scm_array_set_x): minor change to argument error checking.
1621 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
1623 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
1624 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
1625 They should only be included in the library at configure.in's
1627 (libguile_la_LDADD): Include the appropriate .lo files here.
1628 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
1629 so we know when to build them (and their .lo bretheren).
1630 * configure.in (LIBLOBJS): New substituted variable. We let
1631 configure decide which .o files to include in LIBOBJS, and then
1632 put the corresponding list of .lo files in LIBLOBJS. The latter
1633 is what we pass to libtool.
1634 * Makefile.in, configure: regenerated.
1636 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
1638 * symbols.c (scm_sysintern0): New function. Contains the core of
1639 old scm_sysintern but doesn't take a second value argument.
1640 (scm_sysintern): Now uses scm_sysintern0.
1641 (scm_sysintern_no_module_lookup): Renamed to
1642 scm_sysintern0_no_module_lookup and doesn't take a second value
1643 argument any longer.
1645 * symbols.h (scm_sysintern0: Added declaration.
1647 * options.c (scm_init_opts): Use scm_sysintern0 instead of
1648 scm_sysintern when interning option keys. Otherwise we risk
1649 destroying the values of already interned variables.
1651 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
1652 scheme-level boolean (use SCM_NFALSEP).
1654 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
1656 (scm_backtrace): New function. (C version of old function from
1657 boot-9.scm) Motivation: Make it possible to display backtraces
1658 without depending on boot-9.scm. (I'm uncertain if this
1659 motivation is good enough...)
1661 * root.h (scm_root_state): Add member the_last_stack_var.
1662 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
1664 * root.c (mark_root): Mark scm_the_last_stack_var.
1666 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
1669 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
1671 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
1672 1. mark_lazy_catch didn't mark the smob.
1673 2. Both functions above have standard variants:
1674 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
1675 free_lazy_catch --> scm_free0.
1677 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
1679 * throw.c (scm_internal_lazy_catch): New function.
1680 (scm_lazy_catch): Rewritten to use it.
1681 (scm_ithrow): Handle the new lazy catch representation.
1682 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
1683 that doesn't have a jmpbuf is a lazy catch clause.
1684 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
1685 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
1686 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
1688 (scm_init_throw): Register the new lazy-catch smob type.
1689 * throw.h (scm_internal_lazy_catch): decl for new function.
1691 * throw.c (scm_internal_catch): Doc fixes.
1693 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
1694 configure.in. Including this might cause problems if applications
1695 that link against libguile include their own copies of alloca, but
1696 if they're using autoconf, they should be adding libguile to LIBS
1697 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
1698 the copy in libguile, and things will be okay. (I think.)
1700 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1702 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
1704 strop.h: move prototypes too.
1706 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
1708 * posix.c (scm_init_posix): don't intern EINTR since it's now done
1711 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
1712 etc. I deleted them from filesys.c long ago, but didn't
1713 notice they were here too (although ineffective since
1714 sys/stat.h wasn't included).
1716 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
1718 * eval.c: Don't define alloca in GCC case. gcc will automatically
1719 use __builtin_alloca if appropriate.
1721 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
1723 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
1724 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
1725 that values of automatic variables are preserved. See comments
1726 for safe_setjmp for details.
1728 Change from Thomas Morgan:
1729 * variable.c: Include eq.h.
1730 (var_equal): New function.
1731 (variable_smob): Use var_equal as the discriminator for variables.
1733 * throw.c (s_throw): Remove extraneous declaration.
1735 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
1736 * eval.c: Add necessary CPP cruft to support that.
1737 * configure, Makefile.in, scmconfig.h.in: regenerated.
1739 Change from Thomas Morgan:
1740 * procprop.c (scm_procedure_properties): Convert the Scheme
1741 boolean returned by scm_procedure_p into a C boolean before using
1742 it as a condition for SCM_ASSERT.
1743 (scm_procedure_property): Likewise.
1745 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
1746 indications of Unixness.
1749 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
1751 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
1753 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
1755 * read.c (scm_lreadr): use scm_misc_error to improve one of the
1756 "unknown # object" error messages.
1758 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
1759 (scm_i_index) and declare it static. Add a 'direction' argument
1760 to indicate what way the search should go.
1761 (scm_i_index): throw out-of-range error instead of wrong-type-arg
1763 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
1764 strop.h: remove scm_i_index, scm_i_rindex prototypes.
1766 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1768 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
1770 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
1771 to avoid clash with various scsh forks.
1773 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
1775 The following two changes (ramap.c, throw.c) are motivated by the
1776 apparent unportability of forward declarations of static arrays of
1777 the form `static foo bar[];'.
1779 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
1780 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
1782 * throw.c (scm_throw): Moved above scm_ithrow.
1784 * options.h: Removed the extern declarations of scm_yes_sym and
1785 scm_no_sym since these are static.
1787 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1789 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
1791 * Makefile.am: remove AWK=@AWK@.
1792 Add a rule for generating errnos.list.
1793 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
1795 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
1796 don't extract errnos, just set a variable (avoids the
1797 need to recompile error.c just because configure is run.)
1799 * unif.h: update prototypes.
1800 * unif.c (scm_uniform_array_read,write): change the offset and
1801 length arguments to start and end, for consistency.
1803 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
1805 * ioext.h: update prototypes.
1806 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
1807 scm_read_line_x, it's a more general procedure using an
1808 interface from scsh. read-line and read-line! are now defined
1810 Note that the new read-line trims the terminator
1811 by default, previously it was appended to the returned string. An
1812 optional argument specifies how to process the terminator (scsh
1813 compatible). For the old behaviour: (read-line port 'concat).
1814 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
1815 returns a pair, but is converted to multiple values if the scsh
1818 socket.h: update prototypes.
1819 * socket.c (scm_recvfrom): for consistency with other procedures,
1820 take start and end as separate optional arguments.
1821 (scm_recv, scm_recvfrom): don't allow the second argument
1822 to be a size, only a buffer. Change the scheme names to
1823 recv! and recvfrom!. Don't return the buffer.
1825 * ioext.h, posix.h: move prototypes too.
1826 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
1827 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
1828 "read.h" and "unif.h".
1829 * ioext.c: include "chars.h"
1831 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
1833 * dynl.c: The dynamic linking and module registration functions
1834 are now defined even when dynamic linking is not available for the
1835 host system. Some of their functionality can be done without
1836 dynamic linking; when it's really needed, they throw errors.
1838 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
1840 * configure.in: Only define DYNAMIC_LINKING when one of the system
1841 dependent functions is detected.
1842 * dynl.c (scm_dynamic_func): New function to get the address of a
1843 function in a dynamic object.
1844 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
1845 produced by scm_dynamic_func as the thing to call.
1847 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
1849 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
1850 (scm_register_module_xxx, scm_registered_modules,
1851 scm_clear_registered_modules): New functions.
1853 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
1855 * symbols.c (scm_sysintern): Renamed to
1856 scm_sysintern_no_module_lookup.
1857 (scm_sysintern): New function to take the place of the old
1858 scm_sysintern. It uses the current toplevel lookup closure to give
1859 the symbol its value. This is a temporary hack to put packages
1860 like gtcltk into their own module.
1861 (scm_can_use_top_level_lookup_closure_var): New variable to tell
1862 us whether `scm_top_level_lookup_closure_var' has been initialized
1864 * eval.c (scm_init_eval): Set it.
1866 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
1868 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
1869 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
1871 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
1873 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
1874 scm_sys_dup): deleted: FD capability will be added to other
1876 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
1877 scm_fd_free, fd_smob, scm_intern_fd.
1878 (scm_open): renamed from scm_sys_open. Return a port instead of
1879 an FD object. Make the mode argument optional.
1880 (scm_sys_create): deleted, it's just a special case of open.
1881 (scm_init_filesys): move interning of constants O_CREAT etc.,
1882 here (were previously using SCM_CONST_LONG macro).
1883 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
1885 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
1886 include "fports.h" and <stdio.h>
1887 (scm_stat, scm_select): don't support FD objects.
1889 * error.h: adjust scm_syserror_msg prototype.
1890 * error.c (scm_syserror_msg): take an extra argument for errno.
1891 Using the global value didn't always work, since it could be
1892 reset by procedure calls in the message or args arguments.
1894 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
1895 I don't understand why the check was there (and what about the
1898 * strop.c (scm_string_copy): allow shared substrings to be copied.
1900 * unif.h: corresponding change to prototypes.
1901 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
1902 recognize two new optional arguments: offset and length. Allow
1903 the port argument to be an integer (file descriptor, for scsh).
1904 Include <unistd.h> for "read" prototype.
1906 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
1908 * socket.c: don't include filesys.h.
1910 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
1912 * Makefile.am: add AWK=@AWK@ (?)
1914 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
1916 Add a rule to generate errnos.c from errnos.
1917 * error.c (scm_init_error): include errnos.c.
1918 * errnos_cnvt.awk: new file, converts the list of errno codes to
1920 * errnos_get.c: new file.
1921 * errnos.default: new file, contains errnos to try if they can't
1922 be extracted from errno.h.
1923 * configure.in: if using GCC, try and extract errno codes from
1927 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
1929 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
1930 * Makefile.am: Made libguile into a libtool library.
1931 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
1932 Set libtool_libs to indicate that libguile is a libtool library.
1933 See guile/ChangeLog for details.
1934 * .cvsignore: ignore "*.lo", the libtool library objects.
1936 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1938 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
1939 use htons in getservbyport argument.
1941 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
1943 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
1944 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
1947 * objprop.c (scm_object_property): No need to take the CDR of the
1948 value returned by scm_object_properties, since Aug 20 change.
1950 * configure.in: When checking for struct linger, #include
1951 <sys/types.h> as well as <sys/socket.h>. I've never known
1952 <sys/types.h> to cause any portability problems, and Solaris's
1953 <sys/socket.h> needs it.
1954 * configure: Rebuilt.
1956 I think the Sun compiler has chosen a perverse way to interpret
1957 ANSI declarations combined with K&R definitions. We'll
1958 appease it a little bit. But when it invades France, we fight.
1959 * print.c (scm_iprlist): Change 'tlr' argument to an int.
1960 * print.h (scm_iprlist): Here too.
1961 * numbers.c (scm_divbigdig): Change definition to match
1962 declaration in numbers.h.
1963 * unif.c (scm_makflo): Change definition to match declaration in
1966 * init.c (scm_boot_guile): Don't return the value of
1967 scm_boot_guile_1. This function doesn't return a value;
1968 scm_boot_guile_1 doesn't return a value (or return at all).
1970 * eval.c (unmemocopy): Add a semicolon to appease the Sun
1973 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
1974 compile. I have a feeling this function is a bad idea anyway ---
1975 one should always test for features, not systems.
1977 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
1978 semicolons. Only pure luck kept this from being noticed earlier.
1980 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
1982 * socket.c (scm_recvfrom): Added missing semicolon.
1984 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1986 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
1987 the buffer and start and end positions for scsh networking
1990 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
1992 * configure.in: Revert previous change to this file; the problem
1993 is due to transient automake weirdness.
1994 * configure: Rebuilt.
1996 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
1997 PLUGIN/guile.libs. configure generates the latter from the former.
1998 * Makefile.in: Rebuilt.
2000 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
2001 need this if we install scripts, like guile-snarf.
2002 * configure: Rebuilt.
2004 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
2006 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
2008 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
2010 * socket.c (scm_addr_vector): fix faulty scm_listify.
2012 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
2014 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
2015 style block comment is no longer considered an error.
2017 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
2019 * PLUGIN/guile.libs.in: New file.
2020 * PLUGIN/guile.libs: Removed from repository.
2021 * configure.in: Create PLUGIN/guile.libs from
2022 PLUGIN/guile.libs.in. This is for including additonal libraries
2023 needed for dynamic linking.
2024 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
2025 instead of PLUGIN/guile.libs.
2027 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
2029 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
2031 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
2032 occurrences of the given element from the list, not just the
2033 first. This is how the Emacs Lisp functions behave, how the
2034 analogous Common Lisp functions behave, and (I believe) how the
2035 older Maclisp functions worked. I realize that this change may
2036 break code, but it seemed better to break it before the Guile
2039 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
2040 Their prototypes were already present in gc.h, but they weren't
2042 (scm_init_storage): Initialize scm_protects.
2043 * root.c (scm_protects): New element of scm_sys_protects.
2045 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
2047 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
2049 * libguile.h: Added #include "libguile/net_db.h".
2051 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
2052 30 change. That file is only meant for communication between the
2053 configuration process and load.c. If code linked against libguile
2054 wants to get at the paths mentioned in libpath.h, it can call
2055 functions declared in load.h.
2057 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2059 * libguile.h: Removed #include "libguile/fdsocket.h"
2061 * net_db.c: Added #include <sys/socket.h>.
2063 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
2065 * filesys.c (scm_input_waiting_p): use select in preference to
2066 FIONREAD, since the latter doesn't detect EOF.
2067 Throw error if neither select nor FIONREAD available.
2069 * socket.c (scm_connect): take a port, not a fd object.
2070 (scm_fill_sockaddr): throw an error if fam is not recognised.
2071 (scm_bind): use scm_fill_sockaddr.
2072 (scm_listen): take a port, not a fd object.
2073 (scm_accept): take and return a port. return #f in the car if
2074 address can't be got
2075 (scm_sock_fd_to_port): new procedure.
2076 (scm_socket): use scm_sock_fd_to_port.
2077 (scm_addr_vector): throw error if unrecognised address type.
2078 take an extra argument with the calling procedure name.
2079 (scm_getsockname): take a port. return #f if address can't be got.
2080 (scm_getpeername): take a port. return #f if address can't be got.
2081 (scm_recvfrom): take a port. return #f for address component if can't
2083 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
2084 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
2086 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
2088 * throw.c (scm_internal_catch): Make body funcs and handler funcs
2089 use separate data pointers, to allow them to be designed
2090 independently and reused.
2091 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
2092 Renamed from catch_body, catch_handler, and uncaught_throw; made
2094 (struct scm_catch_body_data): Renamed from catch_body_data; moved
2096 (scm_catch): Use the above.
2097 (scm_throw): Don't bother printing a message for an uncaught
2098 throw; we establish a default handler in init.
2099 * throw.h (scm_internal_catch): Prototype updated.
2100 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
2102 (struct scm_body_thunk_data): New structure, used as data
2103 argument to scm_body_thunk.
2104 * init.c (struct main_func_closure): New structure, packaging up
2105 the data to pass to the user's main function.
2106 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
2107 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
2108 scm_internal_catch to establish a catch-all handler, using
2109 scm_handle_by_message. This replaces the special-case code in
2111 (invoke_main_func): Body function for scm_internal_catch; invoke
2112 the user's main function, using the main_func_closure pointer to
2113 decide what to pass it.
2114 * root.c (struct cwdr_body_data): Remove handler_proc member.
2115 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
2116 (cwdr_handler): Removed.
2118 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
2120 * socket.h (SCM_P): update bind prototype.
2121 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
2122 include "feature.h".
2123 (scm_socket): return a port, not a file descriptor object.
2124 include "fports.h" and <unistd.h>
2125 (scm_bind): take a port, not a file descriptor object.
2126 take an extra argument for address args.
2128 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
2129 INADDR_NONE, INADDR_LOOPBACK.
2131 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
2133 * init.c: include net_db.h and not fdsocket.h.
2134 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
2136 * Makefile.am: corresponding changes.
2137 * socket.h: renamed from fdsocket.h, fix names.
2138 * net_db.h: renamed from socket.h, fix names.
2139 * socket.c: renamed from fdsocket.c.
2140 remove _sys from procedure names.
2141 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
2142 add "socket" to features list.
2143 * net_db.c: renamed from socket.c.
2144 remove _sys from procedure names.
2145 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
2146 add "net-db" to features list.
2147 include "net_db.h". don't include <sys/socket.h> or
2150 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2152 * tags.h (scm_tags): Removed comma at end of last enumerator.
2154 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
2156 Don't use GCC extensions to allocate space for debugging frames.
2157 (Here he goes again! Why do we put up with this?!)
2158 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
2159 an scm_debug_info structure, not an in-line array of them. Add
2160 'info' member, to say how many vect elements we've used, for eval
2162 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
2163 a new variable debug_info_end to mark the end of vect, instead of
2164 the address of the 'info' pointer itself.
2165 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
2166 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
2167 (SCM_APPLY): Explicitly allocate space for debug.vect.
2168 * debug.c (scm_m_start_stack): Same, for vframe.vect.
2169 * stacks.c: Adjusted for new debug frame structure.
2170 (RELOC_INFO, RELOC_FRAME): New macros.
2171 (stack_depth, read_frames): Use them, and new scm_debug_frame
2172 element 'info', instead of magically knowing that eval frames have
2173 an info pointer sitting after vect.
2174 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
2176 (scm_init_stacks): Formatting tweaks.
2178 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
2180 Give GCC more control flow information, so it can be sure that
2181 variables aren't used uninitialized.
2182 * error.h (scm_error, scm_syserror, scm_syserror_msg,
2183 scm_sysmissing, scm_num_overflow, scm_out_of_range,
2184 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
2185 scm_misc_error): Tell GCC that these functions never return.
2186 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
2187 out the field type, call abort if SCM_ASSERT returns, to placate
2189 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
2190 scm_wta ever returns. We can't handle this case anyway, and this
2191 gives the optimizer more information.
2192 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
2193 scm_wta ever returns.
2195 In some cases, the code is fine, but GCC isn't smart enough to
2196 figure that out; this usually happens when one variable is only
2197 initialized and used when a particular condition holds true, and
2198 we know that condition will never change within a given invocation
2199 of the function. In this case, we simply initialize the variables
2200 to placate the compiler, hopefully to a value which will cause a
2201 crash if it is ever actually used.
2202 * print.c (scm_iprin1): Initialize mw_pos.
2203 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
2204 * throw.c (scm_ithrow): Initialize dynpair.
2205 * unif.c (scm_uniform_vector_ref): Initialize cra.
2206 * struct.c (init_struct): Initialize prot.
2207 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
2209 * strports.c (scm_eval_0str): Don't return uninitialized garbage
2210 if EXPR contains no expressions.
2212 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2214 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
2215 cause an infinite loop (???). So much for the algebraic
2216 equivalency of variable-sized arrays and alloca...
2218 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
2220 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
2221 a SCM boolean, not a C boolean.
2223 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
2225 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
2226 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
2227 rules for raising scm_mtrigger. Previously, unfortunate but not
2228 unlikely circumstances could result in almost constant invokation
2229 of the gc. Now, this situations should be less likely, but they
2230 are not prevented completely.
2232 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
2234 * numbers.c (scm_fuck): Procedure removed; looks like old test
2236 * numbers.h: Prototype removed.
2238 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
2240 * debug.h (scm_debug_frame): Change `vect' member from an in-line
2241 array to a pointer, to match my Nov 21 change in eval.c.
2243 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2245 * libguile.h: Added #include "libguile/backtrace.h", #include
2246 "libguile/stacks.h".
2248 * strings.c (scm_string scm_make_string scm_string_ref
2249 scm_string_set_x scm_string_equal_p scm_string_append):
2250 Bugfix according to scm patch from Aubrey Jaffer:
2251 Corrected long-standing
2252 (not (eqv? (integer->char 128)
2253 (string-ref (make-string 1 (integer->char 128)) 0)))
2254 bug found by John Kozak <jk@noontide.demon.co.uk>.
2256 * strports.c, strports.h: Make scm_eval_0str return the value of
2257 the last expression evaluated (previously, it returned void).
2259 * strports.c, strports.h: New function: scm_read_0str. Does what
2262 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2264 * simpos.c (scm_getenv): return #f if string can't be found in the
2265 environment instead of throwing an exception, for compatibility
2266 with numerous other systems.
2268 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
2270 * Makefile.am (.c.x): Use guile-snarf.
2271 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
2273 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
2275 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
2277 * backtrace.c (scm_display_error_message): Made non-static, and
2278 renamed from display_error_message.
2279 * backtrace.h (scm_display_error_message): Added extern decl.
2280 * throw.c (uncaught_throw): Use it to display the error message.
2282 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
2284 * inet_aton.c: Use #if 0, not #ifdef 0.
2286 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
2288 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
2289 to convert the returned value.
2290 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
2291 the offset argument.
2293 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
2295 Add new interface to catch/throw, usable from C as well as
2297 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
2298 (scm_internal_catch): New function, replaces...
2299 (scm_catch_apply): Deleted.
2300 * throw.c (scm_catch_apply): Deleted; replaced with a more general
2301 mechanism which is a bit more code, but can be used nicely from C
2302 and implement the Scheme semantics as well.
2303 (scm_internal_catch): This is the replacement; it's named after
2304 the analogous function in Emacs.
2305 (scm_catch): Reimplemented in terms of the above.
2306 (struct catch_body_data, catch_body, catch_handler): New
2307 functions, used by scm_catch.
2308 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
2309 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
2310 support for new cwdr.
2312 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
2315 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
2317 * acconfig.h: Added DYNAMIC_LINKING symbol.
2318 * configure.in: Add option and checks for dynamic linking.
2319 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
2320 dynl.h: New files for dynamic linking support.
2321 * Makefile.am (libguile_a_SOURCES):
2323 (modinclude_HEADERS): Added "dynl.h".
2324 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
2326 * init.c (scm_boot_guile_1): Call
2327 scm_init_dynamic_linking to initialize dynamic linking support.
2329 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
2331 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
2332 (as we Schemers say). It needs to be global, so that I can tweak
2333 it for the proper operation of unexec.
2334 (scm_boot_guile_1_live): New variable, see above.
2336 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
2338 * guile-snarf.sh: Removed.
2339 * PLUGIN/guile.libs: Added dependency for -lm.
2340 * acinclude.m4: Renamed from aclocal.m4.
2341 * PLUGIN/greet: Removed.
2342 * Makefile.am, aclocal.m4: New files.
2343 * configure.in: Updated for Automake.
2345 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
2347 * eval.c (scm_definedp): Use top_level_lookup_closure_var
2348 and not top_level_lookup_thunk_var.
2350 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
2352 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
2354 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
2356 * eval.c (scm_definedp): Incompatibly changed to be a builtin
2357 Scheme function, instead of syntax. Single argument is now a
2360 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2362 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
2363 scm_ra_divide): Properly terminate statements passed as arguments
2364 to IVDEP macros. (Thanks to Bernard Urban.)
2366 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
2367 with non-constant sizes. (Thanks to Bernard Urban.)
2369 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
2371 It's an "eval closure", not an "eval thunk." A thunk is a
2372 function of no arguments.
2373 * root.h (struct scm_root_state): Renamed
2374 top_level_lookup_closure_var from top_level_lookup_thunk_var.
2375 (scm_top_level_lookup_closure_var): Renamed from
2376 scm_top_level_lookup_thunk_var.
2377 * root.c (mark_root): Uses changed.
2378 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
2379 * init.c (scm_start_stack): Uses changed.
2380 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
2381 Change scheme-visible name to *top-level-lookup-closure* from
2382 *top-level-lookup-thunk*.
2384 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
2386 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
2387 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
2389 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
2391 * gc.c (struct scm_heap_seg_data): Doc fixes.
2393 * gc.c (scm_gc_sweep): Empty all segments' freelists before
2394 sweeping. Then, prepend each segment's free cells to its
2395 freelist, rather than wiping out the old value. (Thanks to Marius
2398 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
2399 scm_check_freelist, scm_debug_newcell): New functions and
2400 variables, for debugging freelist problems.
2401 * pairs.h (SCM_NEWCELL): New debugging version added.
2402 * gc.h (scm_debug_newcell): Added extern declaration, used by
2403 debugging version of SCM_NEWCELL.
2405 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2407 On some systems <libc.h> conflicts with <unistd.h>, and should not
2408 be #included at all.
2409 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
2410 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
2411 * configure.in: Call it.
2412 * posix.c, filesys.c: Use its results to decide whether or not to
2414 * configure, scmconfig.h.in: Rebuilt with autoconf and
2417 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2419 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
2420 pointer to the stdio stream before calling scm_setbuf0, so the
2421 latter will be able to retrieve it. I'm surprised this didn't
2422 segfault earlier. (Thanks to Christopher Lee.)
2424 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2426 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
2429 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2431 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
2432 number of stack narrowing specifier pairs. The first specifier in
2433 a pair controls inner border, the second the outer border. A
2434 number means cut that number of frames, a procedure object means
2435 cut until that object is found in operator position in a frame.
2437 * root.c (cwdr): Bugfix.
2439 * read.c: Recording of positions disabled by default.
2441 * procs.c (scm_closure_p): New function.
2443 * posix.c (scm_tmpnam): New function.
2445 * load.c: Added #include "throw.h".
2446 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
2449 * load.c, load.h (scm_read_and_eval_x): New function.
2451 * eval.c: Renamed debug option "deval" to "debug".
2453 (scm_eval_x): `eval!' is no longer accessible from the scheme
2454 level. Motivation: We can't allow operations which introduce
2455 glocs into the scheme level. Guile's type system can't handle
2456 these as data. Use `eval' or `read-and-eval!' as replacement.
2458 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
2459 SCM_CONSP since this is a macro!; Set vframe.prev to
2460 scm_last_debug_frame instead of 0. In this way we can look
2461 "above" the virtual start stack frame if we wish.
2462 (scm_debug_hang): New function: Useful for debugging Guile in
2463 certain tricky situations. Will probably be removed later...
2465 * debug.h: Changed semantics of debug option "backtrace". This
2466 option now only indicates whether we want automatic backtrace at
2469 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2471 * ports.c: #include "filesys.h"
2472 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
2474 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
2475 Motivation: This is system specific code which is related to file
2476 I/O. It also may use select. Added code by Gary Houston to
2477 detect presence of character in stdio buffers.
2479 * libguile.h: #include "libguile/libpath.h"
2481 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
2482 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
2483 SCM_SITE_DIR; Install libpath.h among the other include files.
2485 * load.c, load.h (scm_sys_package_data_dir): New function.
2487 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2489 * stacks.h: Bugfix: Don't use tail-array length field as stack
2490 length field! This screwed GC.
2492 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2494 * _scm.h: Added #ifndef around definition of macros min and max.
2496 * __scm.h: Added hooks for threads to plugin to in ints protection
2497 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
2498 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
2499 the main code in these macros duplicated and spread over multiple
2500 files. Renamed SCM_THREADS_SWITCHING_CODE ->
2501 SCM_THREAD_SWITCHING_CODE.
2503 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
2505 * snarf.h: New file.
2506 * guile-snarf.sh: New file.
2507 * Makefile.in (inner_h_files): Added snarf.h
2508 (ancillary, install, uninstall, distclean): Added actions for
2510 (.c.x): Use guile-snarf.
2511 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
2512 (gen_c_files): Note that these depend on guile-snarf.
2513 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
2514 now in "snarf.h". Added #include "snarf.h" to get them.
2515 * libguile.h: Added #include "snarf.h".
2516 (Patches applied and tweaked by Jim Blandy.)
2518 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
2520 * socket.c: Use K&R style declaration for 'close'; the GNU coding
2521 standards suggest against providing prototypes for system
2522 functions. Thanks to Greg Troxel.
2524 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
2526 * strports.c (scm_eval_0str): New function.
2527 #include "read.h", to get prototype for scm_read.
2528 * Makefile.in (strports.o): Update dependencies.
2529 * strports.h: New prototype.
2531 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
2532 scheme name from "int?" to "integer?". It seems to do the job.
2533 * numbers.h: Rename prototype too.
2534 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
2537 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
2538 scm_num_eq_p): Rename these according to R4RS conventions: call
2539 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
2540 to making libguile R4RS compliant without ice-9...
2542 * load.c (scm_sys_search_load_path): Search for files under all
2543 extensions listed in the %load-extensions variable. If FILENAME
2544 is absolute, return it unchanged, without searching the load path.
2545 (scm_loc_load_extensions): New variable, pointing to
2546 %load-extensions' value cell.
2547 (scm_init_load): Initialize it, and the value it points to.
2548 (scm_primitive_load_path): Improve error reporting.
2550 * load.c (scm_loc_load_hook): New variable, pointing to value cell
2551 of new Scheme variable %load-hook.
2552 (scm_primitive_load): Apply %load-hook to filename.
2554 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
2556 * configure.in: add tests for figuring out whether buffered data
2557 is available in a FILE structure, which is needed by char-ready.
2559 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
2562 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
2563 exceptions using misc_error instead of syserror. It seems a bit
2564 odd to throw an exception if a string can't be found in the
2565 environment, but it's consistent with open-file, stat etc.
2566 (simpos.h): remove sys_ from getenv.
2568 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
2569 occurs, throw an error instead of returning errno. Return value
2571 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
2573 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
2575 * filesys.c (scm_stat2scm): derive file type and permissions from
2576 the stat mode and append them to the returned vector.
2577 There isn't much overhead in doing this and it avoids the need to
2578 work with S_IRUSR et al. in Scheme.
2579 Define symbols scm_sym_regular etc.
2580 (scm_init_filesys): don't intern S_IRUSR etc.
2582 * load.c: change s_try_load and s_try_load_path to s_primitive_load
2583 and s_primitive_load_path.
2585 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
2587 * error.h: don't declare error symbols. prototype for scm_misc_error.
2589 * stackchk.c (scm_stack_overflow_key): defined here instead of in
2592 * error.c: use SCM_SYMBOL to set up error keys.
2593 scm_misc_error: new procedure.
2595 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2597 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
2598 between `#!' and `!#' is ignored.
2599 (skip_scsh_block_comment): New function.
2601 * feature.c (scm_set_program_arguments): New argument, FIRST.
2602 * feature.h: Update prototype.
2603 * init.c (scm_boot_guile_1): Pass new argument to
2604 scm_set_program_arguments.
2606 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
2608 * init.c (scm_start_stack): Don't initialize scm_progargs here.
2609 (scm_boot_guile): Call scm_set_program_arguments here, later than
2610 the old initialization.
2612 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
2613 initialization procedure.
2614 - Delete in, out, err arguments; there are other perfectly good
2615 ways to override these when desired.
2616 - Delete result argument; this function shouldn't ever return.
2617 - Rename init_func argument to main_func, for less confusion.
2618 - Delete boot_cmd argument; main_func is more general.
2619 -Add 'closure' argument, to help people pass data to main_func
2620 without resorting to global variables.
2621 - Abort if reentered; don't bother returning an error code.
2622 - Call scm_init_standard_ports to set up the default/current
2623 standard ports; no need to pass them to scm_start_stack.
2624 - Remove code to evaluate the boot_cmd, and start the repl; let
2625 the user do something like that in main_func if they want.
2626 - Remove code to package up a return value; main_func can do any
2628 - Call exit (0), instead of returning.
2629 (scm_start_stack): Don't initialize the I/O ports here; that's
2630 weird. Delete in, out, err arguments. Move guts to
2631 scm_init_standard_ports, scm_stdio_to_port.
2632 (scm_init_standard_ports): New function, to set up current and
2633 default standard ports.
2634 (scm_start_stack, scm_restart_stack): Make these static.
2635 * init.h (scm_boot_guile): Adjust declaration.
2636 (scm_start_stack, scm_restart_stack): Remove externally
2637 visible declarations for these.
2638 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
2640 * fports.c (scm_stdio_to_port): New function. Its guts used to be
2641 written out several times in scm_start_stack.
2642 * fports.h: New declaration for the above.
2644 * feature.c (scm_set_program_arguments): New function.
2645 * feature.h: New declaration for the above.
2647 * ports.c: Formatting tweak.
2649 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
2651 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
2652 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
2653 for obtaining the address of a car or cdr field. Motivation:
2654 &SCM_CXR make assumptions about the internal structure of the
2657 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
2658 Motivation: see SCM_CXRLOC.
2660 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
2661 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
2662 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
2663 Motivation: Safer use. Some other macros are defined in terms of
2664 these operations. If these are defined using the SCM_SETCXR
2665 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
2666 to inefficiency and an <e1> with side-effects could potentially
2667 break. Also, these particular operations are heavily utilized in
2668 the garbage collector. In unoptimized code there will be a
2671 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
2672 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
2673 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
2674 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
2675 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
2676 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
2677 vports.c: Cleaned up use of pairs: Don't make any special
2678 assumptions about the internal structure of selectors and
2679 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
2680 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
2681 (Among other things, this change makes it easier to build Guile
2682 with certain compilers which have problems with casted lvalues.)
2684 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2686 * stacks.c: Improve selection of relevant stack frames when making
2687 a stack object. Introduce one level of indirection in the stack
2688 object to make it possible to "narrow" to a certain region of the
2689 stack. This facilitates making use of more clever algorithms (not
2690 implemented) for selecting relevant frames and gives a cleaner
2691 design since selection of frames can be done independently of
2692 extraction of frames from the real stack.
2693 (scm_stack_id): Also take #t as argument which means look at
2696 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
2697 Turn n_tail into an integer directly representing current number
2698 of frames in stack. Add field tail.
2700 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
2702 * debug.c (scm_make_memoized): Made it available at scheme level.
2703 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
2704 SCM_NIMP before applying heavier predicates in argument checking.
2705 (scm_local_eval): Also take memoized object as argument.
2707 * backtrace.c (scm_display_error): Just a safety measure: Stacks
2708 aren't created with zero length, but should such a strange
2709 creature suddenly turn up...
2711 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
2713 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
2714 `del', for the sake of C++ compilers. (Patch applied by JimB.)
2716 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
2718 * variable.c (scm_make_variable): Make the name hint optional, as
2720 (anonymous_variable_sym): Renamed from variable_sym. All uses
2723 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
2724 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
2725 of scm_primitive_load_path was also changed to
2726 "primitive-load-path", from "%try-load-path". Callers changed.
2727 We'd like to respect the convention that a function named
2728 "try-mumble" should behave just like the function called "mumble",
2729 but return #f instead of signalling some error.
2730 * load.h: Rename prototypes.
2732 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2734 * print.c (make_print_state, grow_print_state), print.h: Modified
2735 the print state representation: Don't use a tail array for
2736 recording of circular references. Resizing of the print state
2737 structure invalidates the print state pointer. To avoid passing
2738 around an indirect print state reference to all printing
2739 functions, we instead let the print state reference a resizable
2742 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2744 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
2745 Don't crash when passed an improper list terminated by a
2746 non-immediate value.
2748 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
2750 Allocate data for structures on an eight-byte boundary, as
2751 required by the tagging system.
2752 * struct.c (alloc_struct): New function.
2753 (scm_make_struct, scm_make_vtable_vtable): Call it.
2754 * struct.h (scm_struct_n_extra_words): Bump to 3.
2755 (scm_struct_i_ptr): New "field".
2756 * gc.c (scm_gc_sweep): When we need to free the data, use the
2757 information stored by alloc_struct to find the beginning of the
2758 block allocated to the structure, so we can free it.
2760 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2762 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
2765 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
2766 (scm_debug_info): New member: id.
2768 * stacks.c: Stacks are now represented as structs; Stacks have an
2769 id given to them by `start-stack'.
2770 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
2772 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
2773 Changed stack representation.
2775 * debug.c (scm_procedure_name): Try procedure property `name' for
2776 compiled closures aswell.
2778 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
2780 * eval.c: scm_i_name moved to gsubr.c
2781 (scm_m_define): Record names of all kinds of procedure
2782 objects. (Earlier, only closures were recorded.)
2784 * procprop.h: Added declaration of scm_i_name.
2786 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
2787 (scm_make_gsubr): Record names of compiled closures.
2789 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2791 * debug.c, debug.h: Removed obsolete code.
2793 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
2794 stacks.c: Renamed regs --> scm_contregs.
2796 * print.c (scm_free_print_state): Cleanup print state before
2797 returning it to pool. It is better to do it here than in
2798 scm_prin1 since scm_prin1 is called often.
2800 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
2801 s_set_source_property_x): Check that first argument is a pair or a
2804 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
2805 scm_i_line, scm_i_column and scm_i_breakpoint global.
2807 * init.c: Added #include "backtrace.h" and #include "stacks.h".
2808 (scm_boot_guile_1): Added calls to scm_init_backtrace and
2811 * debug.h: Added debug object smob declaration and macro
2814 * configure.in: Build with backtrace.o and stacks.o if debug
2817 * Makefile.in: Added entries for new files: backtrace.c,
2818 backtrace.h, stacks.c and stacks.h.
2820 * symbols.c (scm_sym2ovcell): Fixed documentation.
2822 * _scm.h (min, max): Added.
2824 * async.c: Moved `min' macro to _scm.h.
2826 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
2827 SCM_BACKTRACE_INDENT.
2829 * eval.c: Added new debug options `maxdepth' and `indent'.
2831 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
2833 * print.h: Added selector SCM_PRINT_STATE.
2835 * print.c: New functions: scm_make_print_state,
2836 scm_free_print_state.
2838 * print.h: Added declarations for scm_make_print_state,
2839 scm_free_print_state.
2841 * debug.c (scm_m_start_stack): New acro.
2843 * debug.h: Small cleanup.
2845 * init.c (scm_boot_guile_1): Moved scm_init_debug below
2848 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

2873 More prototype-related changes from Marius Vollmer:
2874 * gdb_interface.h: Wrapped header file in #ifdef/#endif
2875 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
2876 * ports.h (ptobfuns): Added prototypes. This means some casting in
2878 * fports.c: Added casts for initializations, since the functions
2879 are defined to take FILE * as their stream argument, not SCM.
2880 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
2881 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
2882 to `char *str_data' to conform to prototype.
2884 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2886 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
2888 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
2890 * stime.c, stime.h: use SCM_P method.
2892 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2894 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
2895 be given at least two arguments. Insist that lst's last element
2896 be a list, but don't make any requirements of its predecessors.
2898 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2900 * eval.c (scm_nconc2last): Revert last change; there seems to be
2901 other stuff going on here.
2903 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2905 * eval.c (scm_nconc2last): Make sure that each element of lst
2906 (which is a list of argument lists, except for the tail) is a
2907 proper list, i.e., finite and terminated by '().
2909 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
2911 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
2914 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
2915 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
2918 * vectors.c (scm_make_vector): Fill vectors with the undefined
2919 value, to help make Guile Scheme code more portable to other
2922 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
2923 * symbols.h, tags.h: Doc fixes.
2925 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
2927 * async.c (scm_take_signal): Doc fixes.
2929 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
2931 * numbers.c (scm_divbigint): When the remainder is zero, we don't
2932 want to subtract it from the modulus; we just want to leave it
2935 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
2937 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
2940 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
2942 * throw.c (scm_catch_apply): Finished implementation of
2945 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2947 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
2949 (scm_init_filesys): set "i/o-extensions" feature.
2952 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
2954 * Makefile.in (root.o): Correct dependencies.
2956 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
2958 * Makefile.in: Added dependency entry for root.o.
2960 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
2961 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
2963 * init.c (scm_start_stack): Set initial root continuation number
2966 * procs.c: New function: scm_thunk_p.
2968 * procs.h: Added declarations of scm_thunk_p.
2970 * root.c: Renamed `call-with-new-root' -->
2971 `call-with-dynamic-root'.
2972 (cwdr): Removed allocation of new root state. This should be done
2973 separately by use of scm_make_root.
2974 (scm_apply_with_dynamic_root): New function: Does what it
2975 sounds like. Needed when spawning threads.
2977 * root.h: Added member last_debug_frame to root state.
2978 Added #include "libguile/debug.h"
2980 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
2981 arguments. The motivation is that code in root.c needs catch
2982 functionality, and we want to avoid code duplication.
2983 New functions: scm_catch, scm_lazy_catch. These are wrappers for
2984 scm_catch_apply. scm_lazy_catch is intended to introduce catch
2985 handlers that run without popping the stack into the dynwind
2988 * throw.h: Added prototypes for scm_catch_apply and
2991 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2993 * root.h (scm_root, scm_set_root): Decouple thread support details
2994 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
2995 SCM_SET_THREAD_LOCAL_DATA.
2997 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
2998 and tortoise scanning loop.
3000 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
3002 * Makefile.in: Rebuild dependencies.
3004 * libguile.h: #include "libguile/print.h" before "smob.h", since
3005 the latter uses the print_state structure.
3007 * throw.c (scm_ithrow): Use the correct variable when checking to
3008 see if a given element of scm_dynwinds is a valid catch.
3010 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
3011 structure, abort; don't just silently ignore the garbage.
3013 * _scm.h: #include "print.h" here, since it seems to be used just
3015 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
3016 strports.c, unif.h: Don't #include "print.h".
3018 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3020 * feature.h (scm_loc_features): Removed external declaration.
3021 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
3023 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3025 * feature.c (scm_init_feature): Added threads feature (needs to be
3026 initialized here, since features doesn't exist when
3027 scm_init_threads is called).
3029 * libguile.h: Added #include "libguile/../threads/threads.h".
3030 (This is a kludge to get thread support working. This should be
3033 * configure.in, acconfig.h: Added flags for thread support.
3035 * scmsigs.c: Define `signal' to be `pthread_signal' if using
3038 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
3039 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
3042 * _scm.h: Added conditional #include "threads.h"
3044 * __scm.h (SCM_ASYNC_TICK): Added call to macro
3045 SCM_THREADS_SWITCHING_CODE.
3047 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
3048 allocate the basic dynamic root object.
3049 (scm_boot_guile): Added call to scm_init_root.
3051 * root.c, root.h: Added root smob.
3052 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
3053 functions: Implements dynamic roots mostly according to spec in
3054 SCM manual. Main difference is that the second argument is a
3055 throw handler rather than an error "thunk".
3057 * root.h: Added declaration of scm_init_root.
3059 * root.c: Added #include "genio.h", #include "smob.h", #include
3060 "pairs.h", #include "throw.h", #include "dynwind.h", #include
3062 (scm_init_root): Added #include "root.x".
3064 * throw.c: Added #include "stackchk.h"
3065 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
3066 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
3067 can be used in scm_call_with_new_root; Added reenabling of stack
3068 checking when catching a throw.
3070 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
3072 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
3074 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
3075 element is not found, as per R4RS.
3077 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
3079 * list.c: Doc fixes throughout.
3081 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3083 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
3084 declare the char * to be const. Avoids a warning in rgx.c.
3086 * ports.h: spelling fix.
3088 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
3091 * load.c (scm_sys_try_load_path): throw an error if file not found
3092 (like it says it in NEWS).
3094 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
3096 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
3097 PROPS slot to '(), not #f; it's an empty alist.
3099 * throw.h, throw.c: Use SCM_P instead of #if hair.
3101 Remove special support for uncaught throws; see throw.c for
3103 * throw.c (uncaught_throw): New function.
3104 (scm_ithrow): Call uncaught_throw if we don't find a throw
3105 target; don't mess with scm_bad_throw_vcell.
3106 (scm_bad_throw_vcell): Variable deleted.
3107 (scm_init_throw): Don't initialize it.
3109 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
3112 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3114 * numbers.c (scm_istr2int): If the number is short (as most
3115 numbers are), just call scm_small_istr2int to deal with it.
3116 (scm_small_istr2int): New function, created by un-#ifdefing the
3117 non-bignum version of scm_istr2int and renaming it.
3119 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
3121 * load.c (scm_sys_try_load): don't check whether value returned
3122 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
3123 Change the Scheme name from %try-load to primitive-load.
3125 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
3126 Can avoid passing a message, allowing it to be derived in the
3127 error handler (e.g., if we want to throw to the key both from
3130 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
3132 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
3133 references now have a new appearance which is more compact and
3134 also gives a clue about what the target of the reference is.
3135 By setting parameters in the print state, more fancy printing can
3136 be achieved. This is used by the (not yet commited) backtrace
3139 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
3141 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
3144 * print.c: Added #include "struct.h". Removed function
3147 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
3148 scm_iprin1. Removed prototype for scm_prlist.
3150 * arbiters.c (prinarb),
3151 async.c (print_async),
3152 debug.c (prindebugobj, prinmemoized),
3153 eval.c (prinprom, prinmacro),
3154 filesys.c (scm_fd_print, scm_dir_print),
3156 mallocs.c (prinmalloc),
3157 numbers.c, numbers.h (scm_floprint, scm_bigprint),
3158 smob.h (scm_smobfuns),
3159 srcprop.c (prinsrcprops),
3161 unif.c, unif.h (scm_raprin1, rapr1),
3162 variable.c (prin_var): Changed argument `int writing' to
3163 `scm_print_state *pstate'.
3165 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
3166 that it will be called before scm_init_print.
3168 * print.c (scm_prin1): Print states are now allocated when calling
3169 scm_prin1 and then passed around to all printing functions as an
3170 argument. A cache `print_state_pool' enables reuse of print
3172 (scm_make_print_state): New function.
3173 (scm_iprin1): Adaption to print states.
3174 (scm_iprlist): An initial "hare and tortoise" scan brings down
3175 time complexity to O (depth * N). (Better time complexity will be
3176 achieved when the printing code is completely rewritten.)
3178 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3180 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
3181 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
3182 it gets done whether or not the cache variable has a value.
3184 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3186 Distinguish #f and ().
3187 * __scm.h: #undef SICP.
3188 * pairs.h (SCM_EOL): Delete this definition, equating it with
3190 * tags.h (SCM_EOL): Give it a new definition here; I think I found
3191 the value it used to have. Doc fixes, too.
3193 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
3195 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
3196 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
3197 Lord's implementation of structs, allowing for tail arrays as
3198 described in the manual. Also fixed some bugs. (Both the interface
3199 and the implementation should be improved.)
3201 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
3203 * print.c, print.h: Closures now print like #<procedure foo (x)>.
3204 People who whish to see the source can do `(print-enable 'source)'.
3205 Removed #ifdef DEBUG_EXTENSIONS.
3207 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
3209 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
3210 integer (assuming for now accepting an integer is a good thing).
3212 * error.c, fports.c: replace use of %S in lgh_error args with %s.
3213 %S will be used instead for write'ing arguments.
3215 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
3216 asserts. fix a few other asserts.
3217 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
3218 scm_uniform_vector_ref, scm_array_set_x,
3219 scm_dimensions_to_unform_array): change args in
3220 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
3221 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
3222 scm_substring_fill_x): likewise.
3223 gsubr.c (scm_gsubr_apply): likewise.
3224 eval.c (SCM_APPLY): likewise.
3226 * eval.c (4 places): replace scm_everr with lgh_error or
3229 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
3230 scm_memory_error): new procedures.
3231 scm_everr: deleted. can use scm_wta, dropping first two args.
3232 scm_error: convert NULL subr to SCM_BOOL_F.
3234 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
3237 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
3240 * error.c, error.h: new error keys: scm_arg_type_key,
3241 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
3243 scm_wta: reimplement using lgh_error instead of scm_everr.
3245 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
3247 * gdbint.c: scm_lread now has one more argument.
3249 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
3250 scm_port_\1; Added mutator scm_set_port_filename_x (used when
3251 loading source from non-file ports, which, e. g., happens when
3252 using the Emacs interface).
3254 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
3257 * read.c: Added code for recording of positions of source code
3258 expressions; New functions: recsexpr, scm_lreadrecparen;
3259 _scm_make_srcprops --> scm_make_srcprops
3260 (scm_flush_ws): Removed updating of positions counters. This work
3261 is already done by scm_gen_getc
3263 * read.h: Added prototype for scm_lreadrecparen
3265 * print.c: Added #include "alist.h"
3267 * eval.c: Added #include "hash.h"
3269 * eq.c: Added #include "ramap.h"
3271 * options.c: Documentation fixes.
3273 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
3274 (scm_init_srcprop): Adjusted size of initial source-whash. Name
3275 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
3276 --> scm_make_srcprops
3278 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
3279 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
3280 function calls in the definition of the whash access macros.
3282 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
3284 * init.c (scm_boot_guile): Add level of indirection to
3285 scm_boot_guile_1() to ensure that stack base pointer is properly
3286 initialized. There was no guarantee that variable i was the
3287 highest/lowest variable on stack (i.e. the call frame of
3288 scm_boot_guile was not completely protected from gc).
3290 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
3292 * ports.h (scm_port_table): put back file_name, it will be used to
3293 support debugging. Undo related changes in fports.c, ioext.c,
3296 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
3298 * ports.h (scm_port_table): remove file_name member for now, it seems
3300 * fports.c (scm_open_file): don't set file_name in PTAB.
3301 (prinfport): don't use file_name in PTAB.
3302 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
3303 * ports.c (scm_add_to_port_table): don't intialize file_name.
3304 (scm_port_file_name): remove for now.
3305 * gc.c (scm_gc_mark): don't mark PTAB file_name.
3307 * fports.h (scm_mkfile): prototype deleted.
3308 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
3310 * debug.c, unif.c: use scm_out_of_range instead of
3311 wta for range errors (ASSERT still needs work).
3313 * error.c, error.h (scm_out_of_range): new procedure.
3315 * error.c, error.h (scm_out_of_range_key): new key.
3317 * posix.c (scm_sync): #else was missing.
3319 * error.c, error.h: append _key to names scm_num_overflow and
3322 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
3323 of consing an empty list.
3324 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
3325 of macros, saves code and string space.
3326 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
3327 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
3328 lower case. Rename scm_syserror_m to scm_syserror_msg.
3329 error.h: prototypes for new procedures.
3331 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
3333 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
3335 * error.c, error.h: setup scm_num_overflow key.
3337 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
3338 Remove definition of SCM_OVSCM_FLOW.
3340 * fports.c (scm_open_file): use SCM_SYSERROR_M.
3342 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
3343 explicit message and args.
3345 * error.c, error.h, __scm.h: change system_error_sym to
3348 * error.c (system_error_sym): remove leading %% from the Scheme name
3351 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
3353 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3355 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
3356 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
3357 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
3358 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
3359 renamed. (These were introduced by unsupervised name
3362 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3364 * print.c: Added code for detection of circular references during
3365 printing. (init_ref_stack, grow_ref_stack): New functions. Added
3366 a hook for printing of closures (accessible via print options).
3367 This leads to a split of calls to scm_iprin1 into two classes:
3368 elementary print operations (e. g. the code which prints a smob)
3369 still use scm_iprin1 while top level calls (like scm_display) use
3370 scm_prin1. scm_prin1 begins by clearing the data structure used
3371 to record reference information.
3373 * print.h: Added declarations of scm_prin1 and scm_prlist.
3375 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
3377 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
3379 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
3381 * error.c (err_head): scm_iprin1 --> scm_prin1
3383 * debug.c: Adjusted header comment.
3387 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
3389 * strerror.c: Doc fix.
3391 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3393 * gdbint.c (gdb_read): Now possible to run during GC.
3394 (unmark_port, remark_port): New functions.
3396 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
3398 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
3399 of allocating a new string object. Also, increase size by
3400 the factor 2 instead of 1.5.
3402 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
3404 * __scm.h (SCM_P): Corrected to run under traditional C.
3406 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
3409 * async.c: Calls to scm_sysintern corrected.
3411 * async.h (scm_async_clock): Redundant declaration removed.
3413 * continuations.c (scm_dynthrow): Redundant declaration removed.
3415 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
3416 Definition typos corrected.
3418 * debug.h: Missing declarations of functions in debug.c added
3421 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
3422 Missing declarations to functions in eval.c added.
3424 * filesys.c: Possibly uninitialized variable rv.
3426 * gc.h (scm_object_addr, scm_unhash_name): Missing
3427 declarations of functions defined in gc.c added.
3429 * genio.c: Possible typos str_data -> wstr_data. ???
3431 * genio.c: Possibly unintended shadowing of local variable
3432 `int c' (gotos out of scope of inner `c'). ???
3434 * init.c: Uninitialized `SCM last' may be used.
3436 * ioext.h: (scm_sys_isatty_p): Typo.
3438 * list.h (scm_list_head): Missing prototype for function in
3441 * numbers.c (scm_two_doubles): Changed from extern to static
3442 (is used only within numbers.c).
3444 * numbers.h: Repeated declarations removed.
3446 * ports.h (scm_close_all_ports_except): Declaration for the
3447 function defined in ports.c added.
3449 * posix.h: Missing declarations added.
3451 * procs.h (scm_make_subr_opt): Missing declaration added.
3453 * socket.h (scm_sys_gethost): Missing declaration added.
3455 * socket.h: Redundant declarations removed (they are in fdsocket.h).
3457 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
3458 Missing declarations added.
3460 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
3462 * struct.c: Uninitialized variable `SCM answer' may be used.
3464 * unif.c (l2ra): Declaration prototype.
3466 * unif.c (scm_array_equal_p): Dummy definition removed (it is
3467 defined in ramap.c).
3469 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
3470 Redundant declarations removed (they are in ramap.h).
3472 * variable.h (scm_make_udvariable,
3473 scm_make_undefined_variable): Declaration corrected to
3474 correspond variable.c.
3476 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
3477 Missing declarations added.
3479 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
3481 * Makefile.in (distclean): Don't forget to delete fd.h.
3483 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3485 * fd.h.in, tags.h: Trivial cleanups.
3487 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
3488 marksweep.h just declared functions from gc.c.
3489 * gc.h, libguile.h: Don't #include "marksweep.h".
3490 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
3491 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
3492 dependencies updated.
3494 * libguile.h: Don't #include "files.h"; it's been deleted.
3496 * files.c (scm_sys_delete_file): Moved to filesys.c.
3497 File is now empty; deleted.
3499 * filesys.c: scm_sys_delete_file is now here. Remove
3500 #if's; they seem to rely on remnants of an old portability
3501 regimen. If the problems come up again, solve them properly,
3502 using autoconf. Specifically: Don't test M_SYSV, and #define
3503 remove to be unlink if it's #defined; don't use remove just
3504 because HAVE_STDC_HEADERS is #defined.
3505 * filesys.h: Add declarations for scm_sys_delete_file.
3506 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
3507 files.o, files.h, files.c, and files.x.
3508 * init.c: Don't #include "files.h", and don't call scm_init_files.
3510 Use SCM_P instead of PROTO; the latter intrudes on the user's
3512 * params.h: Deleted; definition of SCM_P moved to...
3513 * __scm.h: ... here, where it replaces PROTO macro.
3514 * libguile.h, smob.h: Don't #include "params.h".
3515 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
3516 smob.h: Fix prototypes accordingly.
3517 * Makefile.in: Update dependencies.
3518 (inner_h_files): Remove params.h.
3520 * gc.c: #include "gc.h"; every module should include its header,
3521 to let the compiler cross-check the declarations against the
3524 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
3525 simpos.h: #include "libguile/__scm.h".
3527 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
3529 * init.c: Don't forget to #include smob.h and init.h.
3530 * Makefile.in: Dependencies updated.
3532 * smob.h: Use PROTO instead of #if __STDC__.
3534 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
3536 * __scm.h: Doc fixes.
3538 * __scm.h, libguile.h: Use "quotes" in the #includes, not
3539 <angles>; this allows `make depends' to work properly.
3541 * libguile.h: #include smob.h and pairs.h before the others; they
3542 define typedefs used by other headers.
3544 C files should #include only the header files they need, not
3545 libguile.h (which #includes all the header files); the pointless
3546 recompilation was wasting my time.
3547 * Makefile.in (all .o dependency lists): Regenerated.
3548 * libguile.h: Don't try to get a definition for size_t here...
3549 * __scm.h: Do it here.
3550 * _scm.h: Since this is the internal libguile header, put things
3551 here that all (or a majority) of the libguile files will want.
3552 Don't #include <libguile.h> here; that generates dependencies on
3553 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
3554 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
3555 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

3652 * weaks.c: Get "weaks.h".
3654 * stackchk.h: #include "libguile/debug.h",
3656 * print.h, read.h: #include "options.h", since everyone who uses
3657 either of these files will need that.
3659 * smob.h: #include "ports.h", "genio.h", and "print.h", since
3660 anyone who uses this file will need them to define the smob
3661 printing functions. Also, get markers.h, since people will need
3662 to #define the mark functions.
3664 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
3665 * ports.h: ... to here.
3667 * ports.h (scm_port_table_size): Explicitly give type as 'int';
3668 don't rely on archaic C default type rules.
3670 * fports.h: #include "libguile/ports.h", since you need that in
3671 order to parse this.
3673 * genio.h: #include "libguile/print.h", because you need that to
3674 parse this; don't bother #including "ports.h", since print.h gets
3677 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
3679 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
3680 this; it's now a reference to an element of *scm_root.
3682 * debug.h: Don't #include "options.h"; the compiler won't be able
3683 to find that once the headers are installed; instead, #include
3684 "libguile/options.h".
3685 * gc.h: Same, with marksweep.h.
3686 * mbstrings.h: Same, with symbols.h.
3687 * scmhob.h: Same, with _scm.h.
3688 * smob.h: Same, with params.h.
3690 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
3691 C files; there's no need for this, and it forces recompilations
3694 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
3696 * error.c (scm_error): declare scm_error_callback.
3698 * error.h: prototype for scm_error_callback.
3700 * __scm.h: define lgh_error.
3701 (SCM_SYSERROR): redefine using lgh_error.
3703 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
3705 * error.c (scm_error): new procedure.
3707 * error.h: prototype for scm_error.
3709 * Makefile.in (install): install scmconfig.h from the current
3710 directory, not $(srcdir).
3712 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
3714 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3715 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3716 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

3722 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3723 vports.h, weaks.h: #include "libguile/__scm.h", not
3724 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
3725 dependencies are within libguile properly.
3727 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
3729 * Makefile.in (.c.x): Simplify; there's no need to run this rule
3730 when scmconfig.h doesn't exist.
3732 * load.c (scm_sys_try_load): Correct spelling.
3734 * feature.c (scm_loc_features): Make this static.
3736 * Makefile.in (libpath.h): Omit trailing slash from path. We
3737 shouldn't require it of users, so why put it here?
3739 Move code to initialize and search %load-path from ice-9 to C
3740 code, so we can use the load-path to find the ice-9 boot code;
3741 this makes it easier to run Guile without installing it. See
3742 corresponding changes in guile/Makefile.in.
3743 * feature.c: Move stuff concerned with the load path to load.c.
3744 (scm_compiled_library_path): Deleted.
3745 Don't #include libpath.h here.
3746 * feature.h: Don't mention scm_compiled_library_path.
3747 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
3748 <sys/stat.h>, and <unistd.h> (if present).
3749 (R_OK): #define if the system hasn't deigned to.
3750 (scm_loc_load_path): New variable.
3751 (scm_init_load_path, scm_sys_search_load_path,
3752 scm_sys_try_load_path): New functions.
3753 (scm_init_load): Initialize scm_loc_load_path to point to the
3754 value cell of the Scheme %load-path variable.
3755 * load.h: Add declarations for scm_sys_search_load_path,
3756 scm_sys_try_load_path.
3757 * init.c: Call scm_init_load_path.
3758 * Makefile.in (feature.o, load.o): Dependencies updated.
3760 * load.c, load.h: Rewrite using PROTO macro.
3762 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3764 * gc.c (scm_cellp): New function: C predicate to determine if an
3765 SCM value can be regarded as a pointer to a cell on the heap.
3767 * gc.h: Added declaration of scm_cellp.
3769 * gdb_interface.h: New file: The GDB interface header from the GDB
3772 * gdbint.c: New file: GDB interface.
3774 * gdbint.h: New file: GDB interface.
3776 * libguile.h: Added #include <libguile/gdbint.h>.
3778 * init.c (scm_boot_guile): Added scm_init_gdbint.
3780 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
3781 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
3782 found if object files and source are kept separate).
3784 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
3786 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
3788 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
3790 * configure.in: Don't substitute the values of TCL_SRC_DIR and
3791 TK_SRC_DIR; they're not relevant any more.
3793 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
3794 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
3796 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
3798 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
3799 search path, so we can find the <libguile/MUMBLE.h> headers.
3801 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
3803 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
3804 implicit in the .c.o rule.
3805 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
3808 Put the library path in a header file, instead of passing it on
3809 the command line in every compilation.
3810 * Makefile.in (libpath.h): New target.
3811 (feature.o): Depend on libpath.h.
3812 (clean): Delete libpath.h.
3813 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
3814 * feature.c: ... #include "libpath.h" here.
3815 * .cvsignore: Ignore libpath.h.
3817 Don't install the unwashed masses of Guile header files in the
3818 main #include path; put most of them in a subdirectory called
3819 'libguile'. This avoids naming conflicts between Guile header
3820 files and system header files (of which there were a few).
3821 * Makefile.in (pkgincludedir): Deleted.
3822 (innerincludedir): New variable; this and $(includedir) are enough.
3823 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
3824 (installed_h_files): Divide this up. Now this variable lists
3825 those header files which should go into $(includedir) (i.e. appear
3826 directly in the #include path), and ...
3827 (inner_h_files): ... this new variable says which files appear in
3828 a subdirectory, and are referred to as <libguile/mumble.h>.
3829 (h_files): List them both.
3830 (install): Create innerincludedir, not pkgincludedir. Put
3831 the installed_h_files and inner_h_files in their proper places.
3832 (uninstall): Corresponding changes.
3833 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3834 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3835 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
3836 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
3837 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
3838 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
3839 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
3840 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
3841 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3842 vports.h, weaks.h: Find __scm.h in its new location.
3843 * __scm.h: Find scmconfig.h and tags.h in their new locations
3844 (they're both "inner" files).
3846 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
3848 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
3850 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
3852 * posix.c: Doc fixes.
3854 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
3856 * socket.c: Don't include a prototype for inet_aton; just use a
3857 K&R style declaration, to avoid warnings but minimize the chance
3858 of conflicts with the system.
3860 On NextStep, <utime.h> doesn't define struct utime, unless we
3861 #define _POSIX_SOURCE before #including it.
3862 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
3863 * acconfig.h: New comment text for above CPP symbol.
3864 * configure.in: Call it.
3865 * posix.c: #define _POSIX_SOURCE if it seems necessary.
3867 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
3869 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
3870 testing for __EMX__.
3872 * posix.c: #include <libc.h>, if it exists.
3874 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
3875 don't even know if the latter exists.
3877 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
3878 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
3879 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
3881 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
3883 (scm_init_posix): Use them when initializing the Scheme constants
3886 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3888 * Makefile.in (libdir, includedir, bindir): Use the
3889 autoconf-supplied values, instead of deriving them ourselves.
3890 (pkgincludedir, datadir, pkgdatadir): New variables.
3891 (install, uninstall): Put the header files in a special
3892 subdirectory, not in the main search path.
3894 * Makefile.in (ALL_CFLAGS): Provide the proper value for
3895 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
3897 * Makefile.in (IMPLPATH): Deleted; never used.
3899 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
3900 on the Tcl/Tk source any more.
3901 (INCLUDE_CFLAGS): Remove references to the above.
3903 * Makefile.in (version.o): Corrected dependencies.
3905 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
3907 * libguile.h: #include "version.h"
3909 * init.c (scm_boot_guile): Call scm_init_version.
3910 * gscm.c (gscm_run_scm): Call scm_init_version.
3912 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
3913 GUILE_VERSION): AC_DEFINE these.
3914 (acconfig.h): #undef the above symbols.
3916 * Makefile.in (libobjs): Add version.o.
3917 (installed_h_files): Add version.h.
3918 (c_files): Add version.c.
3919 (gen_c_files): Add version.x.
3920 (version.o): New rule.
3921 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
3922 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
3923 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
3924 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
3925 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
3926 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
3927 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
3928 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
3929 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
3930 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
3931 weaks.o): Add version.h to dependency lists.
3932 (markers.o): Remove duplicate rule.
3934 * version.h: New file.
3936 * version.c: New file.
3938 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3940 * symbols.c (scm_strhash): scm_downcase is now a function, not an
3941 array; use it appropriately. Since GCC is quite happy to
3942 subscript functions, it never warned us about this; we should use
3943 -Wpointer-arith in the future. I guess we never tested
3946 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3948 * socket.c: Doc and copyright fixes.
3950 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3952 * debug.c: Fixed and improved gdb support.
3954 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3956 * socket.c: Added declaration of inet_aton to avoid compiler
3957 warning. (Hope this solution is correct.)
3959 * stime.c: Added declaration of ftime. (This is missing in
3962 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
3964 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3966 * Makefile.in (c_files): add strerror.c.
3968 * strerror.c: new file from Emacs' sysdep.c.
3969 maybe configure should also check for sys_errlist.
3971 * configure.in (AC_REPLACE_FUNCS): add strerror.
3973 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3975 * debug.c (scm_init_debug): Added initialization for
3976 scm_evaluator_traps.
3978 * debug.h, debug.c: Various name changes.
3979 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
3980 "debug-options-interface". See commentary in options.c.
3982 * options.h, options.c: Options now have documentation strings.
3983 Also added a long explanatory commentary.
3985 * eval.c, print.h, print.c, read.h, read.c: Modifications to
3988 * gscm.c, init.c, root.c, throw.c: Bug fixes:
3989 last_debug_info_frame is now updated in all cases.
3991 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
3994 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3996 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
3997 Added option STACK_CHECKING.
3999 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4001 * Makefile.in: Added {debug,options,srcprop}.{h,c}
4003 * __scm.h: Removed symbols for debugging support.
4005 * acconfig.h: Added symbols for debugging support.
4007 * configure.in: Added user option for debugging support.
4008 --enable-debug will include the debugging code into libguile.a.
4010 * continuations.c (scm_make_cont): Enlarged the #if 0 around
4011 scm_relocate_chunk_to_heap.
4013 * debug.c: New file: low-level debugging support. It also
4014 includes support for debugging with gdb. (The extensions to gdb
4015 are written by Per Bothner at Cygnus.)
4017 * debug.h: New file: low-level debugging support.
4019 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
4020 argument pairs. Extensive modifications to the debugging
4021 evaluator. Added "SECTION:" commentaries to clarify what happens
4022 when, during double compilation. Renamed EVALIMP --> EVALIM.
4023 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
4024 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
4025 the beginning of the file. New procedure: scm_unmemocopy.
4026 Added some global state variables needed by the debugging
4027 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
4028 check_entry, check_apply, check_exit, debug_options and
4029 evaluator_traps. New acro: undefine.
4031 * eval.h: Renamed EVAL --> XEVAL.
4033 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
4034 --> scm_make_weak_key_hash_table.
4036 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
4037 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
4039 * libguile.h: Conditionally include debug.h
4041 * objprop.c (scm_object_properties, scm_set_object_properties_x):
4042 scm_object_properties shouldn't return handle. `handle' now gets
4043 initialized in scm_set_object_properties_x. scm_object_properties
4044 doesn't any longer create an entry in scm_object_whash.
4046 * options.c: New file: handling of run time options.
4048 * options.h: New file: handling of run time options.
4050 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
4052 * print.c: New procedure: scm_print_options
4054 * print.h: Defines for print options.
4056 * read.c: New procedure: scm_read_options
4058 * read.h: Defines for reader options.
4060 * root.h: Added scm_source_whash among scm_sys_protects.
4062 * srcprop.c: New file: source properties.
4064 * srcprop.h: New file: source properties.
4066 * throw.c (jbsmob): Jump buffers are now correctly allocated.
4067 (Bug found by A. Green.)
4069 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
4071 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
4073 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
4075 * libguile.h: #include "objprop.h"; I guess this was forgotten.
4077 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
4078 and should be called by the final client.
4080 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
4082 * gc.h: Use the PROTO macro when declaring functions.
4083 * gc.c: Use the PROTO macro when declaring static functions.
4084 Remove the CPP hair around function definitions.
4086 * gc.c (scm_init_storage): Initialize scm_asyncs.
4088 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
4089 preprocessor symbol; "__scm.h" is where it might get #defined.
4090 * __scm.h: Similar: #include <scmconfig.h> before testing
4093 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
4095 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
4097 * init.c (scm_boot_guile): Add init_func argument; call
4098 (*init_func) instead of calling scm_appinit; it's ucky to
4099 hard-code names for the user's procedures.
4100 * init.h (scm_boot_guile): Adjust declaration.
4102 * __scm.h (PROTO): New macro, for declaring functions with
4105 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
4106 eliminate all the __STDC__ conditionals.
4107 (scm_boot_guile): Add declaration.
4108 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
4109 Remove __STDC__ conditionals around function definitions; the
4110 declarations in init.h will provide the same information, more
4113 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
4114 complain about it in the error message; the error message is
4115 adequate without that note, and there's nothing the user can do
4118 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
4120 * Makefile.in (ancillary): Drop def.sed.
4122 * posix.c (scm_init_posix): Use numeric values, rather than
4123 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
4124 F_OK. The symbols aren't available on some systems, and I'm
4125 pretty sure their values are fixed by common widespread practice.
4126 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
4128 More functions unavailable on some systems.
4129 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
4130 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
4132 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
4133 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
4134 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
4135 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
4136 stub that signals an error as the #else.
4138 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
4140 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
4142 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
4144 * unif.c: include ramap.h.
4146 * read.c (endif): case_insensative_p renamed case_insensitive_p.
4148 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
4150 * ports.c: include sys/ioctl.h.
4152 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
4154 * configure.in: check for sys/ioctl.h.
4156 * ports.c: include <malloc.h> not "malloc.h".
4158 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
4160 * fports.c: remove ttyname and tmpnam declarations.
4162 * posix.c: fewer ttyname declarations.
4164 * fports.c: include <string.h> not "string.h".
4166 * init.c, ioext.c: include string.h and unistd.h.
4168 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
4170 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
4171 genio.c, simpos.c, vports.c: include string.h.
4173 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
4175 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
4177 (scm_addr_buffer_size): change type from scm_sizet to int.
4178 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
4179 from scm_sizet to int.
4181 * error.c: include unistd.h.
4183 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
4186 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
4188 * __scm.hd, def.sed: deleted.
4190 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
4192 Changes for NeXT, suggested by Robert Brown.
4193 * configure.in: Call AC_TYPE_MODE_T.
4194 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
4195 NeXT. Put header file list in alphabetical order.
4196 * configure, scmconfig.h.in: Regenerated.
4197 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
4199 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
4202 * acconfig.h: New file, providing documentation for the CPP
4203 symbols defined in configure.in
4204 * acconfig-1.5.h: Removed; superceded by the above.
4206 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
4208 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
4210 * fports.c (scm_open_file): don't return #f, throw error.
4212 * ioext.c (fileno): renamed from %fileno.
4213 (soft-fileno): deleted.
4215 * ports.c (scm_port_revealed): don't need to check for -1 from
4217 (scm_set_port_revealed_x): return unspecified, not #f.
4219 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
4221 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
4223 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
4225 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
4227 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4229 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
4230 This is necessary on Ultrix, and doesn't hurt portability.
4232 * Makefile.in (dist-dir): New target, implementing a new dist system.
4233 (installed_h_files): Put in alphabetical order.
4234 Remove duplicate entries for markers.h and unif.h.
4235 (c_files): Remove duplicate entries for markers.c.
4236 (ancillary): Renamed from anillery; all uses changed. Remove
4237 PLUGIN; it's a directory, and needs special treatment in dist-dir.
4238 Remove all the ../doc/* files; doc/Makefile.in handles that.
4240 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
4242 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
4243 every if must have an else, or else the whole command has a
4244 non-zero exit code whenever the if's condition is false.
4246 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
4248 * posix.c: include string.h.
4250 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4252 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
4255 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
4256 Remove leading % from scheme names.
4257 Do not return error values, call SCM_SYSERROR or similar.
4259 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
4261 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
4263 * struct.c (scm_init_struct): new file.
4265 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
4267 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
4268 (scm_list_head): added list-head for rapidly chopping argument
4269 lists off of longer lists (and similar).
4271 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
4273 * objprop.c (scm_object_property): assq the cdr of the whash
4274 handle for obj, not the handle itself.
4276 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
4278 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
4279 weak hash tables last of all marking to avoid an obscure gc bug.
4280 WARNING: circular lists stored in a weak hash table will hose us.
4282 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
4284 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
4285 new functions similar to scm_substring_move_left_x and
4286 scm_substring_move_right_x.
4288 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
4290 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
4293 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
4295 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
4297 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>

4313 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
4315 * gscm.h: gscm_mkarray eliminated (presumably was not being used

4322 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
4324 * ports.c: removed functions relating to the mapping between ports

4333 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
4334 handled correctly (SCM_FREEP was applied to them) -- test for

4390 * ports.c (scm_add_to_port_table): Added fields

4503 initialization to fix a race condition.
4505 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

4529 set the multi_byte flag correctly in symbols. This is wrong.
4530 intern_obbary_soft and msymbolize should take an extra parameter.

4532 The weird symbol syntax is also a bit bogus (emacs doesn't quite
