24 (scm_tc7_mb_string): Removed.
25 (scm_tc7_mb_substring): Removed.
26 * print.c (scm_iprin1): Handle char printing directly. Don't
28 Don't include "mbstrings.h".
29 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
30 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
32 Don't include "mbstrings.h".
33 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.

47 (SCM_SET_PORT_REPRESENTATION): Removed.
48 * genio.h: Use new function names.
49 * genio.c: Don't include "extchrs.h".
50 (scm_gen_putc, scm_gen_puts, scm_gen_write, scm_get_getc):
52 (scm_putc, scm_puts, scm_lfwrite): No longer static.
53 (scm_getc): No longer static; handle line and column changes.
54 (scm_ungetc): Renamed from scm_gen_ungetc.
55 (scm_do_read_line): Renamed from scm_gen_read_line.

59 1997-10-12 Mark Galassi <rosalia@cygnus.com>
61 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
63 * gh_test_c.c (c_vector_test): some improvements on the vector
66 * gh.h (gh_vector): this used to exist but do the wrong thing.
67 Now it (almost) does the right thing, though it takes a list
68 instead of the individual arguments. I need to see how it could
70 (gh_list_to_vector): added this function as a macro. Corresponds
71 to Scheme's (list->vector ...).
72 (gh_vector_to_list): added this function as a macro. Corresponds
73 to Scheme's (vector->list ...).
75 * gh_data.c (gh_vector_ref): renamed from gh_vref to
76 gh_vector_ref, so that it resembles the Scheme routines more.
77 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
78 resembles the Scheme routines more.
79 (gh_make_vector): this used to be (stupidly) called gh_vector().
80 This is the right name, since it does the same thing as the Scheme
81 (make-vector ...) procedure.
83 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
85 * ports.h: #include "libguile/print.h"
87 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
88 Some indentation fixes.
90 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
91 longer a user field; New field: class_flags.
93 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
95 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
97 * gh_data.c (gh_bool2scm): new function which replaces
98 gh_int2scmb(), which is now tagged as obsolete.
100 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
102 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
103 macros should by convention not test for NIMPness.)
104 (SCM_COERCE_OPORT): Adjust indentation.
106 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
107 SCM_NIMP test before SCM_PRINT_STATE_P.
109 * struct.c, struct.h, gc.c: Renamed:
110 scm_struct_i_layout --> scm_vtable_index_layout
111 scm_struct_i_vcell --> scm_vtable_index_vcell

113 scm_struct_i_printer --> scm_vtable_index_printer
114 scm_struct_i_vtable_offset --> scm_vtable_offset_user
116 * struct.c (scm_print_struct): Use new printer slot; Default
117 printing: Also output hex code of vtable so that type identity
118 will be indicated as well.
119 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
120 Removed struct_printer_var; Removed struct-vtable-offset;
121 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
122 vtable-offset-user): New constants.
124 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
125 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
126 If this slot contains a procedure, use that to print structures of
127 the type represented by this vtable.
129 * print.c (scm_iprin1): Don't print arguments of macro
130 transformers. (They are always: exp env.); Bugfix: Unmemoize
131 transformer source with correct environment.
133 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
135 Streamlining of call-with-dynamic-root:
137 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
138 there is now only one catch.
139 (cwdr_outer_body): Removed.
140 (cwdr_handler): New function.
141 (scm_internal_cwdr): New function to perform the function of cwdr
142 but take args that are more useful to C code. Also, the handler
143 is now invoked *outside* of the new dynamic root, like the docs
144 say. We no longer have to catch absolutely all errors, the caller
145 is responsible for using a handler that does not throw, if he
147 (cwdr): Reimplemented in terms of scm_internal_cwdr.
148 * root.h (scm_internal_cwdr): New prototype.
150 Even more but risky streamlining:
152 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
153 allocation of the jumpbuf of a root continuation. The changes
154 below are controlled by it. They are now deactivated.
155 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
156 the JMPBUF of the scm_rootcont to NULL before returning.
158 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
159 when they are non-NULL.
160 (scm_gc_mark): Likewise, mark only when non-NULL.
162 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
163 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
165 * gc.c (scm_done_malloc): New function.
166 gc.h (scm_done_malloc): New prototype.
168 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
169 (struct scm_print_state) [revealed]: New field.
170 (scm_print_state_vtable): Make visible to the outside world for
171 type checking purposes.
172 (scm_valid_oport_value_p): New prototype.
174 * print.c (scm_valid_oport_value_p): New function to check whether
175 a certain value is acceptable as a port argument.
176 (scm_print_state_vtable): New variable.
177 (scm_free_print_state): Set `revealed' field to false.
178 (scm_iprin1): Call user supplied closure printer with
179 scm_printer_apply. Print in the traditional way when there isn't
180 one or when it returns #f.
181 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
182 Accept a port/print-state pair in addition to just a port.
183 (scm_prin1): Don't return the print_state to the pool when it has
185 (scm_printer_apply): Set `revealed' field of print_state to true.
186 (scm_init_print): Set scm_print_state_vtable.
187 (print_state_fluid, print_state_fluid_num): Removed.
189 * throw.h (scm_handle_by_proc_catching_all): New prototype
190 throw.c (scm_handle_by_proc_catching_all): New function
192 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
194 * Makefile.in: Regenerated with automake 1.2c.
196 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
198 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
199 was looping endlessly.
201 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
203 * strports.c (scm_eval_string): Don't close the port.
205 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
206 former returns a nice normal integer. (Thanks to Daniel
209 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
211 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
212 makefile variable as a build parameter called LIBS. The
213 build-guile program will use this, for the time being.
214 * Makefile.in: Regenerated.
216 Thanks to Shiro Kawai:
217 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
218 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
221 * Makefile.in: Regenerated with automake 1.2a.
223 * script.c (scm_compile_shell_switches): If we hit the -c or --
224 arguments, don't set the car of (command-line) to scm_usage_name,
225 the prettified name of the guile executable; give it the full
226 path, the way shells usually handle $0.
228 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
230 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
231 Scheme-level name `array-map' and renamed `serial-array-map' to
234 * backtrace.c: Introduced exception handlers which now enclose
235 `display-error' and `display-backtrace' so that error reporting
236 won't get into infinite loops if an error occurs during displaying
237 of the error. This can very easily happen with user supplied
238 print call-back routines.
240 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
242 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
243 the names `serial-array-map' and `array-map' should be removed.)
245 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
247 * init.c (scm_boot_guile_1): Added scm_init_objects ().
248 Added #include "objects.h"
250 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
251 Add #include "feature.h".
253 * Makefile.am (libguile_la_SOURCES): Added objects.c.
254 (modinclude_HEADERS): Added objects.h.
256 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
257 This test is needed at many places in the code and should be
258 abstracted. (Motivated by the need of this test in libguiletk.)
260 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
261 (scm_eval_string), load.c (scm_primitive_load,
262 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
263 Use SCM_EOF_OBJECT_P.
265 * eval.c (scm_init_eval): Add feature `delay'.
267 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
271 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
273 * list.h (SCM_LISTn): New macros. Make list creation in C code
274 prettier. The idea comes from STk.
276 * sequences.h, sequences.c, append.h, append.c: Removed. These
277 files implemented non-R4RS operations which would encourage
278 non-portable programming style and less easy-to-read code.
280 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
283 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
284 sequences.h, #include append.h.
286 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
289 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
291 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
293 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
295 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
297 * eval.c: Added #include "objects.h"
299 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
302 * smob.c (scm_smob_prehistory): Create two objectsmobs with
303 adjacent smob numbers.
305 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
307 * procprop.h: Added declaration of scm_i_inner_name.
309 * gsubr.c: New global symbol scm_i_inner_name.
311 * debug.c (scm_procedure_name): Try procedure property
312 `inner-name' if `name' fails.
314 * print.c (scm_iprin1): Use scm_macro_name.
316 * eval.c (scm_m_define): Give names to macros as well; Only the
317 first top-level definition gives a procedure/macro a name.
318 Otherwise confusing names can turn up in backtraces.
319 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
320 `name'; Give names to macros as well.
322 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
323 (scm_macro_transformer): Use SCM_CLOSUREP instead of
326 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
328 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
330 (prinmacro): Removed. The code has been moved/merged into print.c
331 in order to decrease code redundancy. We want macros to print in
332 a way equivalent to procedures, and it would be silly to duplicate
333 the required code. (We don't want to maintain two places.)
334 (macrosmob): Print field is now a NULL pointer.
336 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
337 scm_macro_transformer): New prototypes.
338 (scm_tc16_macro): Declared.
340 * * print.c (scm_iprin1): Added code for printing of macros. Macros
341 are now printed in a way equivalent to procedures.
343 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
345 * procs.h (scm_closure_p): Added declaration.
347 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
349 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
350 Shouldn't pass "heap" as the subr name.
352 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
354 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
355 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
356 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
357 gh_equal_p): Use SCM_NFALSEP, instead of testing against
358 SCM_BOOL_T. Any non-false value is true.
360 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
362 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
363 scm_gensym): Added prototypes.
365 * symbols.c (scm_gensym): New function. This will speed up
366 certain types of applications (such as macro systems) which
367 generate lots of symbols.
369 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
371 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
373 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
375 * unif.c (scm_shap2ra): tighten the checking of the array dimension
376 specifier, since (2) or (2 . 3) would cause SEGV.
377 (scm_transpose_array): more argument checking fixes.
379 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
381 * Makefile.in: Regenerated.
383 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
385 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
387 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
389 * error.c, error.h (scm_error_callback): Removed (see NEWS).
391 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
393 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
394 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
397 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
398 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
399 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
400 scm_array_p, scm_array_rank, scm_array_dimensions,
401 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
402 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
403 scm_array_prototype): Added case scm_tc7_wvect.
405 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
407 * errno.h: prototype for scm_strerror.
408 * error.c (scm_strerror): new procedure.
410 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
412 * list.c (scm_list_append_x): Allow non-pair as last argument.
413 This is consistent with the R4RS append and is probably the
414 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
416 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
418 * stime.h: prototype for scm_times.
419 * stime.c (scm_times): new procedure.
420 * ioext.c (scm_fseek): if the first argument is a file descriptor
422 (scm_ftell): if the first argument is a file descriptor call lseek
424 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
425 * filesys.c (scm_chmod): if the first argument is a file descriptor,
427 (scm_chown): if the first argument is a port or file descriptor,
429 (scm_truncate_file): new procedure.
430 Add DEFER/ALLOW INTS to a few other procedures.
431 (scm_fsync): new procedure.
432 (scm_open_fdes): new procedure.
433 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
435 (scm_fcntl): the first argument can now be a file descriptor. The
436 third argument is now optional.
438 * posix.c (scm_execl, scm_execlp): make the filename argument
439 compulsory, since omitting it causes SEGV.
440 (scm_sync): return unspecified instead of #f.
441 (scm_execle): new procedure.
442 (environ_list_to_c): new procedure.
443 (scm_environ): use environ_list_to_c. disable interrupts.
444 (scm_convert_exec_args): take pos and subr arguments and
445 improve error checking.
447 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
449 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
450 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
451 argument to SCM_ASSERT. Furthermore, the name of the function
452 should be passed as first argument when signalling
453 SCM_WNA. (Thanks to Thomas Morgan)
455 * gsubr.c (scm_gsubr_apply): From Radey Shouman
456 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
457 dispatches on the number of actual args has a default case
458 reporting an internal error. This is a vestige from a version
459 that mallocated a SCM vector to hold the arguments. In the
460 current version this check is too late: if it ever happens we will
461 have already overstepped the bounds of the array.
463 Also, the patch [...] adds a check for too many actual arguments."
465 mdj: Removed check for "internal programming error".
467 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
469 * gh_io.c (gh_write): New function.
471 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
472 throw.c (scm_internal_stack_catch): New sibling to the other catch
473 functions. Code moved from gh_eval.c.
474 throw.h: Added header.
475 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
476 scm_internal_stack_catch.
478 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
480 * ioext.h: fix up prototypes.
481 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
482 Scheme name is now dup->fdes.
483 (scm_dup_to_fdes): make the second argument optional and
484 fold in the functionality of scm_primitive_dup.
485 (scm_primitive_dup): deleted.
487 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>

494 (scm_setfileno): moved from ioext.c.

553 * ioext.c (scm_primitive_dup2): return the new file descriptor
554 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup

558 (scm_duplicate_port): deleted, there's now an implementation in
560 (scm_primitive_dup2): do nothing if newfd == oldfd.
562 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
564 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the

613 the dynamic object data below the linking of the object to avoid
614 memory leak when the linking code throws an error. Now the code
615 leaks a whole dynamically linked library when must_malloc throws,
616 but that should be much less likely.
618 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
620 Changes to compile under gnu-win32, from Marcus Daniels:

627 (scm_addr_vector): Likewise.
628 (scm_init_addr_buffer): Likewise.

632 * scmsigs.c (scm_pause): Don't include unless pause was found
634 * posix.c (scm_getgroups): Don't include unless support function

656 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of

661 DEBUG_EXTENSIONS isn't #defined.
663 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>

688 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
689 argument and logior its components together, so the user doesn't
690 have to do this explicitly. Also, if regexp/basic is supplied, then
691 turn off REG_EXTENDED.
692 (scm_init_regex_posix): New regexp/basic symbol.
693 (REG_BASIC): #define this if it is not already present.
695 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

712 flag; I don't think we support it.
713 (scm_make_regexp): Make sure the user doesn't pass the
716 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
718 (scm_init_regex_posix): Define constants for the REG_mumble flags;
719 name them according to the SCSH convention: regexp/mumble.
721 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.

734 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
736 * root.c: Establish a reliable catch-all handler for the new root.
737 After all the Scheme handler function might signal an error too,
738 and we don't want to lose that.
739 (cwdr_inner_body): Renamed from cwdr_body.
740 (cwdr_outer_body): New function, to establish the user's handler,
741 and pass control to cwdr_inner_body.

743 control to cwdr_outer_body.
744 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
745 the user's handler through to cwdr_outer_body.
746 * throw.c (scm_handle_by_message): Move guts into....
747 (handler_message): New static function.

749 * throw.h (scm_handle_by_message_noexit): New prototype.
751 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
752 across this. Only works on GCC. Otherwise, we hope for the best.
753 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
754 the feeling that real thread systems will not need this...
756 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
758 Try to detect when people are using one version of libguile and a

770 primitive definitions under their Scheme names.
772 * Makefile.am (libguile_la_LDFLAGS): Update library version to
773 1:2. Helps avoid confusion between installed and uninstalled libs.
775 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
778 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
779 backslash from definition; this should be used like: GDB_INTERFACE;
781 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
783 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
784 new port unbuffered until its stream has been set.
786 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
788 * ports.h: new prototype.
789 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
791 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>

794 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
795 * extchrs.c (xmbtowc): Make the second arg a normal char, not
796 unsigned, because that's what the ANSI function takes.
797 * extchrs.h (xmbtowc): Corresponding change to prototype.
798 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
800 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
801 argument plain char *.
802 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
804 * tag.c (scm_tag): Remove unreachable statement.
805 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
806 top of the word, it should be unsigned.
808 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
809 is defined, to avoid warnings; it's only used in the
810 conflict-checking code. Which might go away anyway.
811 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
812 conditionals; put the label definition in an #if too, to stifle
815 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
816 ChangeLog-threads in the distribution.
817 * Makefile.in: Regenerated.
819 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
821 * guile-snarf.in: Changed regexp to support CPPs that insert

827 * load.c (scm_init_load_path): Append $(datadir)/guile to
828 %load-path, so modules do not have to be installed in Guile's
829 current version directory.

833 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
834 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
835 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
836 call the sysdep functions with deferred ints.

865 supplied. (Change from Tim Pierce.)
867 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
869 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
870 23:47:01 1997" changelog: Slots are now initialized with `#f' by
871 default and not `()'. `#f' is the canonical non-value in Scheme,
874 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
876 * struct.c (struct_printer): New variable that holds a handle on
877 the Scheme variable *struct-printer*. This variable can be set by
878 Scheme code to override the printing of structures.
879 (scm_print_struct): If struct_printer is set, call it. If it is
880 not set, or returns #f, print the structure in the old fashion.
881 Include "eval.h" for scm_apply.
883 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
885 * struct.c (scm_struct_ref, scm_struct_set_x): Use
886 scm_struct_i_n_words to get the number of fields, not
887 -scm_struct_n_extra_words.
889 On the route to fancier struct printing:
890 * struct.c (scm_print_struct): New function to print a structure.
891 Include "genio.h" to support it. This function doesn't do
892 anything interesting right now, but I think it should be here
894 * struct.h: Include "print.h" and add prototype for
896 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
897 print structures ourself.
899 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
901 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]

908 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
911 * posix.c (scm_uname): interpret only negative values as an error.
912 Solaris normally returns a positive value.
914 * script.c (scm_compile_shell_switches): if we are not going into
915 an interactive repl, set scm_mask_ints to zero so that asyncs can
918 * simpos.c (scm_system): don't ignore/unignore signals around
921 * posix.c (scm_open_pipe): don't ignore/unignore signals around
924 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
925 done in boot-9.scm instead.
927 * scmsigs.c, async.c: Major rewriting of signal handling code.
928 (scm_sigaction): new procedure.
929 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
931 (scm_raise): return unspecified, throw error on failure.
933 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
935 * regex-posix.c (scm_init_regex_posix): Register the "regex"
936 feature, to help boot-9.scm decide whether to import the regex
939 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
941 * eval.c: Include scmconfig.h at the beginning of the file so that
942 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
945 * regex-posix.c: #include "_scm.h" before conditionally #including
946 <regex.h>; the former defines HAVE_REGCOMP.
948 * regex-posix.c: #include <regex.h> conditionally, so the file is
949 CPP'able (for dependency scanning) even on systems that don't have
952 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
954 Add new R4RS-compliant syntax for keywords.
955 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
956 regardless of the setting of the `keywords' read option.
957 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
958 can be re-read no matter what the setting of the `keywords' read
961 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
963 Add support for POSIX regular expressions.
965 * regex-posix.c, regex-posix.h: New files. (Some code

968 * init.c: Include regex-posix.h.
969 (scm_boot_guile_1): Call scm_init_regex_posix.
971 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
972 Add regex-posix.[ch] sources.
973 * Makefile.in: Regenerated.
975 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
976 to do this automatically? It didn't for me, bleh.)
978 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
980 * fports.c (print_pipe_port): New function.
981 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
982 latter doesn't even take the right arguments.
984 * Makefile.am: Increment shared lib revision number. I think
985 sometimes the uninstalled Guile finds the installed shared lib;
986 Gord says doing this might help. As things turned out, I can't
988 * Makefile.in: Regenerated.
990 * gh_init.c (gh_enter): Cast c_main_prog to a void * before

995 write_void_port, flush_void_port, getc_void_port, close_void_port,
996 noop0): Use ANSI prototypes instead of K&R declarations, so the
997 initialization of void_port_ptob gets aggressively type-checked.

1034 * script.c (scm_find_executable): Use prototype-style definition
1035 here; apparently it's not quite right to have const in a prototype
1036 and then use a K&R declaration. I wonder if stuff like this will
1037 go away if we compile with -Wrequire-prototypes, or whatever that
1038 is... (Bernard URBAN)
1040 * scmhob.h: New text from Bernard URBAN.
1042 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
1044 * script.c: Don't #define const on hpux. Configure takes care of
1045 this. (Thanks to Larry Schwimmer.)
1047 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
1048 decide whether to #include <unistd.h>, instead of listing a bunch
1049 of systems. Don't #include stdio twice. Removed dyked-out
1050 definition of scm_find_impl_file.
1052 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
1054 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
1055 library version info to 1:0.
1056 * Makefile.in: Regenerated.

1063 throw.c: Update copyright years; these files have been worked on
1064 significantly in 1997, but only had copyright years for 1996.
1065 Also, change name of copyright holder on some from Mikael
1066 Djurfeldt to Free Software Foundation; he has signed papers
1067 assigning the changes to the FSF.
1069 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
1070 reason not to give the user the option.
1072 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
1073 Return #f on end-of-file when scanning table (i.e. when called
1074 with no arguments). Try to catch errors, when we can.
1075 * posix.c (scm_getgrgid, scm_getpwuid): Same.
1077 * script.h (scm_shell_usage, scm_compile_shell_switches): New
1078 external declarations. These are useful.
1080 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
1082 * posix.c: don't include <sys/select.h> or define macros for
1083 select, since they were not used in this file.
1085 * filesys.c (scm_select): make the fifth parameter microseconds,
1086 not milliseconds. let the fourth parameter be either a real value
1087 or an integer or #f. The first, second and third arguments can
1088 now be vectors: the type of the corresponding return set will be
1090 (set_element, get_element): new static procedures.
1092 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
1094 * strports.c (scm_eval_string): New function.
1095 (scm_eval_0str): Trivially re-implemented in terms of
1097 * strports.h (scm_eval_string): New extern decl.
1099 * net_db.c (h_errno): Add extern decl for this.
1101 * fports.c (local_pclose): New function.
1102 (scm_pipob): Use it in the initializer here.
1105 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
1106 Use a meaningful error message when signalling an error. For
1107 this, scm_gethost must check h_errno rather than errno.
1109 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
1111 * Makefile.in: Regenerated, using automake-1.1p.
1113 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
1115 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
1116 not SCM_UNSPECIFIED.
1118 * script.c (scm_compile_shell_switches): don't append (quit) if
1120 (scm_shell): call scm_exit_status and exit on the result of the
1123 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
1125 Ensure that shared substrings are handled properly when passed to
1126 a system call or other foreign function. Many thanks to Tim
1128 * symbols.h (SCM_COERCE_SUBSTR): new macro.
1129 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
1130 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
1131 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

1133 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
1134 (scm_display_error_message): use RO macros when strings may be RO.
1135 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
1136 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
1137 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

1141 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
1142 scm_strftime), vports.c (scm_make_soft_port): use
1143 SCM_COERCE_SUBSTR to make sure shared substrings are
1146 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
1148 * error.c (scm_error): Add newline to error message.
1150 * init.c (scm_init_standard_ports): Doc fix.
1152 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1154 * dynl-shl.c: Completely replaced with new code from Bernard
1157 * script.c (scm_ice_9_already_loaded): New variable.
1158 (scm_compile_shell_switches): Use it.
1160 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1162 * filesys.c (scm_input_waiting_p): add missing third argument to
1165 * stime.c (scm_localtime): copy the result of localtime before
1166 calling gmtime in case they share a buffer.
1167 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
1170 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1172 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
1174 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
1176 * Makefile.am (check-local): New target, which causes 'make check'
1177 to run gh_test_c and gh_test_repl, with some trivial input.
1178 * Makefile.in: Rgnrtd.
1180 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
1182 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
1185 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
1187 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
1188 sure how this was supposed to work.
1189 (scm_async_click): don't send SCM_TICK_SIGNAL.
1190 (scm_init_async): don't initialize %tick-thunk.
1192 * the following change doesn't affect the Scheme interface:
1193 gc-thunk is called at the end of garbage collection. however it's
1194 no longer implemented by pretending it's a signal.
1196 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
1197 system async corresponding to scm_gc_thunk.
1198 * async.h: declare scm_gc_async.
1199 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
1200 gc-thunk directly, instead of going through a signal handler.
1201 (scm_gc_async): new variable, points to the GC system-async.
1202 (scm_init_async): save the GC async as scm_gc_async instead
1203 of using system_signal_asyncs.
1204 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
1206 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
1208 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
1209 Don't screw up if we're interrupted.
1210 * Makefile.in: Regeneradet.
1212 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
1214 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
1216 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
1217 we're not using AM_INIT_GUILE_MODULE any more.
1218 * Makefile.in: Reneregated.
1220 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
1222 Functions for finding variable bindings, grace à Tim Pierce.
1223 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
1224 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
1226 Get 'make dist' to work again.
1227 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
1228 * Makefile.in: Regenerated, like a surry without a fringe on top.
1230 Changes for reduced Guile distribution: one configure script,
1232 * configure.in, configure: Removed.
1233 * acconfig.h, acinclude.m4: Moved to parent directory, where the
1234 real configure script lives.
1235 * Makefile.in, scmconfig.h.in: Regenerated.
1237 * init.c: #include "script.h", to get prototype for script.c's
1240 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
1242 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
1243 scm_must_malloc, not raw malloc.
1245 * script.c (scm_compile_shell_switches): Dyke out debugging output
1248 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1250 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
1252 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
1253 system has them. Hope this is safe. Previously
1254 sys/timeb.h was included if HAVE_FTIME was defined or if
1255 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
1256 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
1258 * ioext.c (scm_setfileno): add missing third argument to
1259 scm_misc_error call.
1261 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
1263 * eq.c (scm_equal_p): Correctly compare strings of different
1264 varieties. (Thanks to Tim Pierce.)
1266 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
1268 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
1269 #! block comment must occur on a line all by itself.
1271 Move most of the guts of shell command processing into libguile,
1272 so guile.c can be very small (and eventuallly auto-generated. (I
1273 mean, generated mechanically, not self-generated. Hmm.))
1274 * guile.c, script.c, script.h: New source files.
1275 * init.c (scm_boot_guile_1): Call scm_init_script.
1276 * libguile.h: #include "script.h".
1277 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
1278 targets, for new executable.
1279 (libguile_la_SOURCES): Mention script.c.
1280 (modinclude_HEADERS): Add script.h.
1281 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
1282 not dynamic linking is enabled. This is because we're generating
1283 executables now. Move CY_AC_WITH_THREADS call after those, so the
1284 values of cy_cv_threads_libs captures the libs chosen above.
1285 * Makefile.in, configure, aclocal.m4: Regenerated.
1287 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
1288 We don't maintain this interface any more, and it just confuses
1291 * alloca.c: #include <scmconfig.h>, not <config.h>.
1292 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
1293 it'll get included in disties.
1295 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
1297 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
1298 be distributed, because they confuse people.
1299 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
1301 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
1303 * configure.in: check for presence of gethostent (not present on
1304 OpenBSD by default).
1305 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
1306 * configure, scmconfig.h.in: Regenerated.
1308 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
1310 * backtrace.c (scm_backtrace): Split message string across
1311 newlines properly. GCC is more tolerant of this than other
1314 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
1316 Merge threads directory into libguile.
1317 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
1318 threads.h: New source files.
1319 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
1320 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
1322 (modinclude_HEADERS): Add threads.h, coop-defs.h.
1323 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
1324 coop-threads.c.cygnus, coop-threads.h.cygnus.
1325 * configure.in: If we're using threads, include threads.o in
1327 * _scm.h, libguile.h: threads.h lives in this directory now.
1328 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
1329 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
1330 currently used, but brought along for information's sake.
1331 * ChangeLog-threads: log from old 'threads' directory.
1332 * Makefile.in, configure: Rebuilt.
1334 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
1336 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
1339 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
1341 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
1343 Merge GH interface library into libguile.
1344 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
1345 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
1346 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
1347 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
1349 (EXTRA_libguile_la_SOURCES): ... here.
1350 (pkginclude_HEADERS): Add variable, to get gh.h installed.
1351 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
1352 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
1353 New variables, describing how to build the gh test programs.
1354 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
1355 build the test programs, and we probably should have been linking
1356 libguile.la against them all along, to support AIX shared libs.
1357 Add cflags for threads to CFLAGS; add libs for threads to new
1358 variable THREAD_LIBS, used in Makefile.am.
1359 * ChangeLog-gh: log from old `gh' subdirectory.
1360 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
1362 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
1364 * acconfig.h: Undo change of Apr 9; including the definition of
1365 PACKAGE in the guile headers conflicts with applications' own
1367 * scmconfig.h.in: Regenerated.
1369 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
1371 * filesys.c (scm_fcntl): New function from Roland McGrath.
1372 (scm_init_filesys): New symbols for use with fcntl.
1373 * filesys.h: Added prototype.
1375 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
1376 when PROC is receiving no arguments.
1378 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
1380 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
1381 have S_IFSOCK. This is the case under Ultrix.
1383 * posix.c (scm_status_exit_val, scm_status_exit_val,
1384 scm_status_term_sig, scm_status_stop_sig): Modified to work with
1385 Ultrix versions of WIFSTOPPED, etc., which assume that their
1386 arguments are lvalues (hmm).
1388 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
1390 * eval.c: Doc fixes.
1392 * throw.c: Doc fixes; rearranged.
1394 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
1396 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
1398 * acconfig.h: Added entry for PACKAGE.
1399 * scmconfig.h.in: Regenerated.
1401 Changes to work with automake-1.1n, which has better libtool support.
1402 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
1403 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
1405 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
1407 * Makefile.in: Rebuild.
1409 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1411 * stime.c (scm_mktime): take an optional zone argument.
1412 (scm_localtime): check putenv return value.
1413 (scm_strftime, scm_strptime): moved from posix.c. move #include
1415 stime.h, posix.h: update prototypes.
1416 (bdtime2c, setzone, restorezone): new static procedures.
1417 (scm_mktime, scm_strftime): use them.
1418 (scm_strftime): don't call mktime before strftime. Use
1419 filltime for return value.
1420 (filltime): convert NULL zname to #f.
1421 (scm_strptime): return a count of characters consumed, not
1422 the remaining string.
1424 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1426 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
1427 (scm_mktime): likewise.
1429 Uncomment localtime and mktime.
1431 * configure.in: add AC_STRUCT_TIMEZONE.
1433 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
1435 * stime.c (scm_init_stime): don't define ticks/sec.
1436 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
1437 return value problem and is still portable.)
1439 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
1441 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
1442 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
1443 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
1444 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
1445 cpp_err_symbols.c): Corresponding changes.
1446 * Makefile.in: Regenerated.
1448 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
1450 * posix.c (scm_putenv): don't check HAVE_PUTENV.
1451 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
1452 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
1453 * putenv.c: new file, from sh-utils 1.12.
1455 * posix.c (scm_environ): use malloc in place of scm_must_malloc
1456 since allocation isn't for Scheme objects.
1457 (scm_putenv): copy strings before placing in the environment.
1459 * stime.c (scm_current_time): throw an error if time returns -1,
1460 instead of returning #f.
1461 (scm_get_internal_real_time, scm_get_internal_real_time): use
1462 scm_long2num for return value instead of SCM_MAKINUM.
1464 * stime.h: prototypes updated.
1466 * stime.c (scm_time_in_msec): apparently unused, deleted.
1468 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
1470 * configure.in: check for gettimeofday.
1472 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
1473 which may be more usefully portable than a gettimeofday interface.
1475 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
1477 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
1479 * Makefile.in: Regenerated.
1481 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
1483 * stime.c (filltime): recovered static procedure.
1484 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
1487 * posix.h: add prototype for scm_close_pipe, remove prototypes for
1488 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
1490 * posix.c (scm_mknod): split the mode argument into type and perms
1491 arguments, like the extra fields returned by stat.
1493 * fports.c (scm_pipob): set the close, free and print procedures.
1494 (scm_close_pipe): new procedure.
1496 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
1497 define them in boot-9.scm
1499 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1501 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
1502 wan't defined. Don't include fd.h.
1504 * Previously fd.h was regenerated whenever configure was run,
1505 forcing a couple of files to be recompiled.
1507 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
1508 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
1509 Check for _fileno as well as _file.
1511 * ioext.c: don't fd.h.
1512 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
1515 * Change the stratigy for getting information about errno
1516 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
1517 generating lists of symbols during the build process, which will
1518 not always work, include comprehensive lists in the distribution.
1519 To help keep the lists up to date, the "check_signals" and
1520 "check_errnos" make targets can be used.
1522 * configure.in: don't check for a command to extract errno codes.
1523 * Makefile.am: update file lists, remove errnos.list and errnos.c
1524 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
1525 check_errnos targets.
1526 (CLEANFILES): remove errnos.c and errnos.list, add
1527 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
1528 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
1529 * errnos.default: deleted.
1530 * cpp_signal.c: new file.
1531 * cpp_errno.c: renamed from errnos_get.c.
1532 * cpp_err_symbols, cpp_sig_symbols: new files.
1533 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
1534 * error.c (scm_init_error): #include cpp_err_symbols instead of
1536 * posix.c (scm_init_posix): don't intern signal symbols. #include
1539 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
1541 * strop.c (scm_i_index): allow the lower bound to be equal to the
1542 length of the string, so a null string doesn't always give an error.
1544 * posix.h: new prototypes.
1545 * posix.c (scm_status_exit_val, scm_status_term_sig,
1546 scm_status_stop_sig): new functions, as in scsh. They break down
1547 process status values as returned by waitpid.
1549 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
1551 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
1552 configure doesn't know about it.
1554 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1556 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
1558 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
1559 which defines C variables with global linkage.
1561 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1563 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
1566 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
1568 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
1569 has time to check why this doesn't work well with continuations.
1571 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
1573 * Fix shell syntax error; some shells won't tolerate
1574 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
1576 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
1578 * posix.c (scm_uname): throw an error if uname fails instead
1581 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
1583 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
1586 * async.c (scm_ints_disabled): definition moved from error.c.
1588 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1590 * acconfig.h: Removed PACKAGE.
1592 * scmconfig.h.in: Regenerated.
1594 * snarf.h: g++ says it's non-portable not to specify the first
1595 argument in a varargs declaration. I introduced the first
1596 argument by using preprocessor conditionals.
1598 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
1600 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
1601 (scm_freopen): use RO string macros for filename and modes.
1602 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
1604 * posix.c (scm_getgrgid): simplify conversion of name to C string.
1605 (scm_mknod): use RO string macros for path.
1607 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
1608 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
1610 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
1611 use SCM_ROSTRINGP and SCM_ROCHARS.
1613 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1615 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
1618 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
1619 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
1620 support for byte vectors.
1622 * print.c (scm_iprin1): Limit number of vector elements printed
1623 according to pstate->length.
1625 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
1627 * backtrace.c (scm_display_error_message): don't segv if message
1630 * error.h: prototype for scm_error_scm.
1632 * error.c (scm_error_scm): new procedure, reimplements scm-error
1633 in C and uses scm_error.
1635 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
1637 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
1638 pointer to the Scheme variable read-hash-procedures and intern it
1639 in scm_init_read. Modify scm_read_hash_extend and
1640 scm_get_hash_procedure to use the pointer.
1642 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1644 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
1645 (SCM_KEYWORD_STYLE): defined.
1647 * read.c (scm_read_opts): add a keywords option. This isn't a
1648 boolean option, in case someone wants to add support for DSSSL
1650 Setup scm_keyword_prefix symbol.
1651 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
1653 I've left keyword support disabled by default, since it doesn't
1654 seem to break the module system and it gives R4RS standard behaviour.
1655 It can be reactivated with (read-set! keywords 'prefix).
1657 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1659 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
1660 before constructing arbiter.
1662 * eval.c (scm_m_define): Bugfix: Check that the object is a
1663 closure before setting the procedure property!
1665 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
1667 * ports.c: Removed `ungetc-char-ready?'.
1669 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
1671 * read.c (scm_init_read): intitialise scm_read_hash_procedures
1672 (idea from Mikael: make it a pair so scm_permanent object only
1674 (scm_read_hash_extend): don't call scm_permanent_object.
1675 (ideas from Mikael): if chr is already in the list, replace its
1676 procedure instead of appending it again. If proc is #f, remove
1678 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
1680 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
1682 * gdbint.c (gdb_read): update scm_lreadr usage.
1684 * load.h: update prototypes.
1686 * load.c (scm_primitive_load, scm_read_and_eval_x,
1687 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
1689 * read.h: add prototype for scm_read_hash_extend. Change args for
1692 * read.c (scm_read_hash_procedures): new variable.
1693 (scm_read_hash_extend): new procedure.
1694 (scm_get_hash_procedure): new procedure.
1695 (scm_lreadr): use scm_get_hash_procedure instead of an argument
1696 for extended # processing.
1697 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
1698 scm_read_token): remove case_i, sharp arguments. Change callers.
1700 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
1702 * read.h (SCM_N_READ_OPTIONS): increase to 3.
1703 (SCM_CASE_INSENSITIVE_P): define.
1705 * read.c: add case-insensitive option to scm_read_opts.
1706 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
1707 to determine whether to convert symbol case.
1708 (default_case_i): definition removed.
1709 * read.c (scm_read_token): if case_i, downcase ic before doing
1712 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1714 * configure.in: Added configuration option `guile-debug'.
1715 Configure with --enable-guile-debug if you want a bunch of extra
1716 functions used for debugging when developing Guile.
1718 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
1720 * procs.c (make-cclo): New undocumented debugging procedure: Make
1721 compiled closure with internal procedure PROC and length LENGTH.
1722 Only compiled if GUILE_DEBUG is defined.
1724 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
1726 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
1728 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
1730 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
1731 with 3 or more args internally to the evaluator.
1733 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1735 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
1736 with 3 or more args internally to the evaluator. This is mainly
1737 because we don't want to pass entry and exit points of the
1738 debug support twice, but it also seems to increase the speed of
1739 the evaluator for such calls (e. g. (+ 1 2 3)).
1741 * backtrace.c (scm_display_application): New procedure:
1742 display-application; Set fancy printing parameters individually
1743 for different types of display (backtrace, error, application).
1744 (These should of course be customizable!)
1746 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
1747 clear the CHECK-flags.
1749 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1751 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
1753 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1755 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
1756 from pairs with a GLOC in the car.
1758 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
1759 otherwise `symbol-hash' will behave badly.
1760 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
1761 we get segmentation fault!
1763 * symbols.c: Added #include "weaks.h". New functions:
1764 `builtin-bindings' and `builtin-weak-bindings'. (These will be
1765 moved to an extraneous library when we split libguile.)
1767 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1769 * filesys.c (scm_stat): stat now takes fport arguments too as
1770 documented in the manual.
1772 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1774 * debug.c (scm_single_step): Bugfix: Call continuation with
1775 scm_call_continuation instead of throwing to it.
1777 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1779 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
1780 argument wasn't declared to be optional.
1782 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1784 * stime.c (scm_init_stime): Add feature "current-time".
1786 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
1788 * throw.h: prototype for scm_exit_status.
1789 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
1790 args to derive an exit status. Allows (quit) to work from a
1792 (scm_exit_status): new function.
1795 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1797 * eval.c (scm_deval): Removed some old code.
1798 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
1800 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
1803 * symbols.c (msymbolize): Bugfix: Must initialize property list to
1806 * procs.c: Introduce the existent C function scm_thunk_p at the
1807 Scheme level as well.
1809 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1811 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
1812 used from C to easily lookup the value of a symbol in the current
1815 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1817 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
1818 scm_init_unif in this file. This will also fix a previous problem
1821 * configure.in: Added AM_MAINTAINER_MODE
1823 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1825 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
1828 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1830 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
1831 source files that are not always included in libguile but should
1832 have their dependencies calculated by automake. This variable is
1833 recognized by automake, no further magic is needed.
1834 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
1835 to deal exclusively with *.lo files, as it seems. The *.o files
1836 are built automatically when the corresponding *.lo file gets
1839 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
1841 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
1844 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
1846 * unif.c (scm_array_set_x): minor change to argument error checking.
1848 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
1850 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
1851 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
1852 They should only be included in the library at configure.in's
1854 (libguile_la_LDADD): Include the appropriate .lo files here.
1855 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
1856 so we know when to build them (and their .lo bretheren).
1857 * configure.in (LIBLOBJS): New substituted variable. We let
1858 configure decide which .o files to include in LIBOBJS, and then
1859 put the corresponding list of .lo files in LIBLOBJS. The latter
1860 is what we pass to libtool.
1861 * Makefile.in, configure: regenerated.
1863 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
1865 * symbols.c (scm_sysintern0): New function. Contains the core of
1866 old scm_sysintern but doesn't take a second value argument.
1867 (scm_sysintern): Now uses scm_sysintern0.
1868 (scm_sysintern_no_module_lookup): Renamed to
1869 scm_sysintern0_no_module_lookup and doesn't take a second value
1870 argument any longer.
1872 * symbols.h (scm_sysintern0: Added declaration.
1874 * options.c (scm_init_opts): Use scm_sysintern0 instead of
1875 scm_sysintern when interning option keys. Otherwise we risk
1876 destroying the values of already interned variables.
1878 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
1879 scheme-level boolean (use SCM_NFALSEP).
1881 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
1883 (scm_backtrace): New function. (C version of old function from
1884 boot-9.scm) Motivation: Make it possible to display backtraces
1885 without depending on boot-9.scm. (I'm uncertain if this
1886 motivation is good enough...)
1888 * root.h (scm_root_state): Add member the_last_stack_var.
1889 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
1891 * root.c (mark_root): Mark scm_the_last_stack_var.
1893 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
1896 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
1898 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
1899 1. mark_lazy_catch didn't mark the smob.
1900 2. Both functions above have standard variants:
1901 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
1902 free_lazy_catch --> scm_free0.
1904 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
1906 * throw.c (scm_internal_lazy_catch): New function.
1907 (scm_lazy_catch): Rewritten to use it.
1908 (scm_ithrow): Handle the new lazy catch representation.
1909 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
1910 that doesn't have a jmpbuf is a lazy catch clause.
1911 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
1912 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
1913 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
1915 (scm_init_throw): Register the new lazy-catch smob type.
1916 * throw.h (scm_internal_lazy_catch): decl for new function.
1918 * throw.c (scm_internal_catch): Doc fixes.
1920 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
1921 configure.in. Including this might cause problems if applications
1922 that link against libguile include their own copies of alloca, but
1923 if they're using autoconf, they should be adding libguile to LIBS
1924 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
1925 the copy in libguile, and things will be okay. (I think.)
1927 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1929 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
1931 strop.h: move prototypes too.
1933 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
1935 * posix.c (scm_init_posix): don't intern EINTR since it's now done
1938 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
1939 etc. I deleted them from filesys.c long ago, but didn't
1940 notice they were here too (although ineffective since
1941 sys/stat.h wasn't included).
1943 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
1945 * eval.c: Don't define alloca in GCC case. gcc will automatically
1946 use __builtin_alloca if appropriate.
1948 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
1950 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
1951 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
1952 that values of automatic variables are preserved. See comments
1953 for safe_setjmp for details.
1955 Change from Thomas Morgan:
1956 * variable.c: Include eq.h.
1957 (var_equal): New function.
1958 (variable_smob): Use var_equal as the discriminator for variables.
1960 * throw.c (s_throw): Remove extraneous declaration.
1962 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
1963 * eval.c: Add necessary CPP cruft to support that.
1964 * configure, Makefile.in, scmconfig.h.in: regenerated.
1966 Change from Thomas Morgan:
1967 * procprop.c (scm_procedure_properties): Convert the Scheme
1968 boolean returned by scm_procedure_p into a C boolean before using
1969 it as a condition for SCM_ASSERT.
1970 (scm_procedure_property): Likewise.
1972 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
1973 indications of Unixness.
1976 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
1978 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
1980 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
1982 * read.c (scm_lreadr): use scm_misc_error to improve one of the
1983 "unknown # object" error messages.
1985 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
1986 (scm_i_index) and declare it static. Add a 'direction' argument
1987 to indicate what way the search should go.
1988 (scm_i_index): throw out-of-range error instead of wrong-type-arg
1990 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
1991 strop.h: remove scm_i_index, scm_i_rindex prototypes.
1993 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1995 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
1997 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
1998 to avoid clash with various scsh forks.
2000 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
2002 The following two changes (ramap.c, throw.c) are motivated by the
2003 apparent unportability of forward declarations of static arrays of
2004 the form `static foo bar[];'.
2006 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
2007 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
2009 * throw.c (scm_throw): Moved above scm_ithrow.
2011 * options.h: Removed the extern declarations of scm_yes_sym and
2012 scm_no_sym since these are static.
2014 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2016 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
2018 * Makefile.am: remove AWK=@AWK@.
2019 Add a rule for generating errnos.list.
2020 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
2022 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
2023 don't extract errnos, just set a variable (avoids the
2024 need to recompile error.c just because configure is run.)
2026 * unif.h: update prototypes.
2027 * unif.c (scm_uniform_array_read,write): change the offset and
2028 length arguments to start and end, for consistency.
2030 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
2032 * ioext.h: update prototypes.
2033 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
2034 scm_read_line_x, it's a more general procedure using an
2035 interface from scsh. read-line and read-line! are now defined
2037 Note that the new read-line trims the terminator
2038 by default, previously it was appended to the returned string. An
2039 optional argument specifies how to process the terminator (scsh
2040 compatible). For the old behaviour: (read-line port 'concat).
2041 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
2042 returns a pair, but is converted to multiple values if the scsh
2045 socket.h: update prototypes.
2046 * socket.c (scm_recvfrom): for consistency with other procedures,
2047 take start and end as separate optional arguments.
2048 (scm_recv, scm_recvfrom): don't allow the second argument
2049 to be a size, only a buffer. Change the scheme names to
2050 recv! and recvfrom!. Don't return the buffer.
2052 * ioext.h, posix.h: move prototypes too.
2053 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
2054 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
2055 "read.h" and "unif.h".
2056 * ioext.c: include "chars.h"
2058 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
2060 * dynl.c: The dynamic linking and module registration functions
2061 are now defined even when dynamic linking is not available for the
2062 host system. Some of their functionality can be done without
2063 dynamic linking; when it's really needed, they throw errors.
2065 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
2067 * configure.in: Only define DYNAMIC_LINKING when one of the system
2068 dependent functions is detected.
2069 * dynl.c (scm_dynamic_func): New function to get the address of a
2070 function in a dynamic object.
2071 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
2072 produced by scm_dynamic_func as the thing to call.
2074 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
2076 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
2077 (scm_register_module_xxx, scm_registered_modules,
2078 scm_clear_registered_modules): New functions.
2080 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
2082 * symbols.c (scm_sysintern): Renamed to
2083 scm_sysintern_no_module_lookup.
2084 (scm_sysintern): New function to take the place of the old
2085 scm_sysintern. It uses the current toplevel lookup closure to give
2086 the symbol its value. This is a temporary hack to put packages
2087 like gtcltk into their own module.
2088 (scm_can_use_top_level_lookup_closure_var): New variable to tell
2089 us whether `scm_top_level_lookup_closure_var' has been initialized
2091 * eval.c (scm_init_eval): Set it.
2093 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2095 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
2096 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
2098 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
2100 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
2101 scm_sys_dup): deleted: FD capability will be added to other
2103 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
2104 scm_fd_free, fd_smob, scm_intern_fd.
2105 (scm_open): renamed from scm_sys_open. Return a port instead of
2106 an FD object. Make the mode argument optional.
2107 (scm_sys_create): deleted, it's just a special case of open.
2108 (scm_init_filesys): move interning of constants O_CREAT etc.,
2109 here (were previously using SCM_CONST_LONG macro).
2110 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
2112 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
2113 include "fports.h" and <stdio.h>
2114 (scm_stat, scm_select): don't support FD objects.
2116 * error.h: adjust scm_syserror_msg prototype.
2117 * error.c (scm_syserror_msg): take an extra argument for errno.
2118 Using the global value didn't always work, since it could be
2119 reset by procedure calls in the message or args arguments.
2121 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
2122 I don't understand why the check was there (and what about the
2125 * strop.c (scm_string_copy): allow shared substrings to be copied.
2127 * unif.h: corresponding change to prototypes.
2128 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
2129 recognize two new optional arguments: offset and length. Allow
2130 the port argument to be an integer (file descriptor, for scsh).
2131 Include <unistd.h> for "read" prototype.
2133 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2135 * socket.c: don't include filesys.h.
2137 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
2139 * Makefile.am: add AWK=@AWK@ (?)
2141 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
2143 Add a rule to generate errnos.c from errnos.
2144 * error.c (scm_init_error): include errnos.c.
2145 * errnos_cnvt.awk: new file, converts the list of errno codes to
2147 * errnos_get.c: new file.
2148 * errnos.default: new file, contains errnos to try if they can't
2149 be extracted from errno.h.
2150 * configure.in: if using GCC, try and extract errno codes from
2154 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
2156 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
2157 * Makefile.am: Made libguile into a libtool library.
2158 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
2159 Set libtool_libs to indicate that libguile is a libtool library.
2160 See guile/ChangeLog for details.
2161 * .cvsignore: ignore "*.lo", the libtool library objects.
2163 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2165 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
2166 use htons in getservbyport argument.
2168 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2170 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
2171 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
2174 * objprop.c (scm_object_property): No need to take the CDR of the
2175 value returned by scm_object_properties, since Aug 20 change.
2177 * configure.in: When checking for struct linger, #include
2178 <sys/types.h> as well as <sys/socket.h>. I've never known
2179 <sys/types.h> to cause any portability problems, and Solaris's
2180 <sys/socket.h> needs it.
2181 * configure: Rebuilt.
2183 I think the Sun compiler has chosen a perverse way to interpret
2184 ANSI declarations combined with K&R definitions. We'll
2185 appease it a little bit. But when it invades France, we fight.
2186 * print.c (scm_iprlist): Change 'tlr' argument to an int.
2187 * print.h (scm_iprlist): Here too.
2188 * numbers.c (scm_divbigdig): Change definition to match
2189 declaration in numbers.h.
2190 * unif.c (scm_makflo): Change definition to match declaration in
2193 * init.c (scm_boot_guile): Don't return the value of
2194 scm_boot_guile_1. This function doesn't return a value;
2195 scm_boot_guile_1 doesn't return a value (or return at all).
2197 * eval.c (unmemocopy): Add a semicolon to appease the Sun
2200 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
2201 compile. I have a feeling this function is a bad idea anyway ---
2202 one should always test for features, not systems.
2204 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
2205 semicolons. Only pure luck kept this from being noticed earlier.
2207 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
2209 * socket.c (scm_recvfrom): Added missing semicolon.
2211 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2213 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
2214 the buffer and start and end positions for scsh networking
2217 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
2219 * configure.in: Revert previous change to this file; the problem
2220 is due to transient automake weirdness.
2221 * configure: Rebuilt.
2223 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
2224 PLUGIN/guile.libs. configure generates the latter from the former.
2225 * Makefile.in: Rebuilt.
2227 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
2228 need this if we install scripts, like guile-snarf.
2229 * configure: Rebuilt.
2231 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
2233 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
2235 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
2237 * socket.c (scm_addr_vector): fix faulty scm_listify.
2239 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
2241 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
2242 style block comment is no longer considered an error.
2244 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
2246 * PLUGIN/guile.libs.in: New file.
2247 * PLUGIN/guile.libs: Removed from repository.
2248 * configure.in: Create PLUGIN/guile.libs from
2249 PLUGIN/guile.libs.in. This is for including additonal libraries
2250 needed for dynamic linking.
2251 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
2252 instead of PLUGIN/guile.libs.
2254 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
2256 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
2258 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
2259 occurrences of the given element from the list, not just the
2260 first. This is how the Emacs Lisp functions behave, how the
2261 analogous Common Lisp functions behave, and (I believe) how the
2262 older Maclisp functions worked. I realize that this change may
2263 break code, but it seemed better to break it before the Guile
2266 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
2267 Their prototypes were already present in gc.h, but they weren't
2269 (scm_init_storage): Initialize scm_protects.
2270 * root.c (scm_protects): New element of scm_sys_protects.
2272 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
2274 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
2276 * libguile.h: Added #include "libguile/net_db.h".
2278 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
2279 30 change. That file is only meant for communication between the
2280 configuration process and load.c. If code linked against libguile
2281 wants to get at the paths mentioned in libpath.h, it can call
2282 functions declared in load.h.
2284 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2286 * libguile.h: Removed #include "libguile/fdsocket.h"
2288 * net_db.c: Added #include <sys/socket.h>.
2290 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
2292 * filesys.c (scm_input_waiting_p): use select in preference to
2293 FIONREAD, since the latter doesn't detect EOF.
2294 Throw error if neither select nor FIONREAD available.
2296 * socket.c (scm_connect): take a port, not a fd object.
2297 (scm_fill_sockaddr): throw an error if fam is not recognised.
2298 (scm_bind): use scm_fill_sockaddr.
2299 (scm_listen): take a port, not a fd object.
2300 (scm_accept): take and return a port. return #f in the car if
2301 address can't be got
2302 (scm_sock_fd_to_port): new procedure.
2303 (scm_socket): use scm_sock_fd_to_port.
2304 (scm_addr_vector): throw error if unrecognised address type.
2305 take an extra argument with the calling procedure name.
2306 (scm_getsockname): take a port. return #f if address can't be got.
2307 (scm_getpeername): take a port. return #f if address can't be got.
2308 (scm_recvfrom): take a port. return #f for address component if can't
2310 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
2311 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
2313 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
2315 * throw.c (scm_internal_catch): Make body funcs and handler funcs
2316 use separate data pointers, to allow them to be designed
2317 independently and reused.
2318 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
2319 Renamed from catch_body, catch_handler, and uncaught_throw; made
2321 (struct scm_catch_body_data): Renamed from catch_body_data; moved
2323 (scm_catch): Use the above.
2324 (scm_throw): Don't bother printing a message for an uncaught
2325 throw; we establish a default handler in init.
2326 * throw.h (scm_internal_catch): Prototype updated.
2327 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
2329 (struct scm_body_thunk_data): New structure, used as data
2330 argument to scm_body_thunk.
2331 * init.c (struct main_func_closure): New structure, packaging up
2332 the data to pass to the user's main function.
2333 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
2334 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
2335 scm_internal_catch to establish a catch-all handler, using
2336 scm_handle_by_message. This replaces the special-case code in
2338 (invoke_main_func): Body function for scm_internal_catch; invoke
2339 the user's main function, using the main_func_closure pointer to
2340 decide what to pass it.
2341 * root.c (struct cwdr_body_data): Remove handler_proc member.
2342 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
2343 (cwdr_handler): Removed.
2345 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
2347 * socket.h (SCM_P): update bind prototype.
2348 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
2349 include "feature.h".
2350 (scm_socket): return a port, not a file descriptor object.
2351 include "fports.h" and <unistd.h>
2352 (scm_bind): take a port, not a file descriptor object.
2353 take an extra argument for address args.
2355 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
2356 INADDR_NONE, INADDR_LOOPBACK.
2358 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
2360 * init.c: include net_db.h and not fdsocket.h.
2361 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
2363 * Makefile.am: corresponding changes.
2364 * socket.h: renamed from fdsocket.h, fix names.
2365 * net_db.h: renamed from socket.h, fix names.
2366 * socket.c: renamed from fdsocket.c.
2367 remove _sys from procedure names.
2368 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
2369 add "socket" to features list.
2370 * net_db.c: renamed from socket.c.
2371 remove _sys from procedure names.
2372 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
2373 add "net-db" to features list.
2374 include "net_db.h". don't include <sys/socket.h> or
2377 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2379 * tags.h (scm_tags): Removed comma at end of last enumerator.
2381 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
2383 Don't use GCC extensions to allocate space for debugging frames.
2384 (Here he goes again! Why do we put up with this?!)
2385 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
2386 an scm_debug_info structure, not an in-line array of them. Add
2387 'info' member, to say how many vect elements we've used, for eval
2389 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
2390 a new variable debug_info_end to mark the end of vect, instead of
2391 the address of the 'info' pointer itself.
2392 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
2393 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
2394 (SCM_APPLY): Explicitly allocate space for debug.vect.
2395 * debug.c (scm_m_start_stack): Same, for vframe.vect.
2396 * stacks.c: Adjusted for new debug frame structure.
2397 (RELOC_INFO, RELOC_FRAME): New macros.
2398 (stack_depth, read_frames): Use them, and new scm_debug_frame
2399 element 'info', instead of magically knowing that eval frames have
2400 an info pointer sitting after vect.
2401 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
2403 (scm_init_stacks): Formatting tweaks.
2405 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
2407 Give GCC more control flow information, so it can be sure that
2408 variables aren't used uninitialized.
2409 * error.h (scm_error, scm_syserror, scm_syserror_msg,
2410 scm_sysmissing, scm_num_overflow, scm_out_of_range,
2411 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
2412 scm_misc_error): Tell GCC that these functions never return.
2413 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
2414 out the field type, call abort if SCM_ASSERT returns, to placate
2416 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
2417 scm_wta ever returns. We can't handle this case anyway, and this
2418 gives the optimizer more information.
2419 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
2420 scm_wta ever returns.
2422 In some cases, the code is fine, but GCC isn't smart enough to
2423 figure that out; this usually happens when one variable is only
2424 initialized and used when a particular condition holds true, and
2425 we know that condition will never change within a given invocation
2426 of the function. In this case, we simply initialize the variables
2427 to placate the compiler, hopefully to a value which will cause a
2428 crash if it is ever actually used.
2429 * print.c (scm_iprin1): Initialize mw_pos.
2430 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
2431 * throw.c (scm_ithrow): Initialize dynpair.
2432 * unif.c (scm_uniform_vector_ref): Initialize cra.
2433 * struct.c (init_struct): Initialize prot.
2434 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
2436 * strports.c (scm_eval_0str): Don't return uninitialized garbage
2437 if EXPR contains no expressions.
2439 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2441 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
2442 cause an infinite loop (???). So much for the algebraic
2443 equivalency of variable-sized arrays and alloca...
2445 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
2447 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
2448 a SCM boolean, not a C boolean.
2450 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
2452 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
2453 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
2454 rules for raising scm_mtrigger. Previously, unfortunate but not
2455 unlikely circumstances could result in almost constant invokation
2456 of the gc. Now, this situations should be less likely, but they
2457 are not prevented completely.
2459 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
2461 * numbers.c (scm_fuck): Procedure removed; looks like old test
2463 * numbers.h: Prototype removed.
2465 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
2467 * debug.h (scm_debug_frame): Change `vect' member from an in-line
2468 array to a pointer, to match my Nov 21 change in eval.c.
2470 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2472 * libguile.h: Added #include "libguile/backtrace.h", #include
2473 "libguile/stacks.h".
2475 * strings.c (scm_string scm_make_string scm_string_ref
2476 scm_string_set_x scm_string_equal_p scm_string_append):
2477 Bugfix according to scm patch from Aubrey Jaffer:
2478 Corrected long-standing
2479 (not (eqv? (integer->char 128)
2480 (string-ref (make-string 1 (integer->char 128)) 0)))
2481 bug found by John Kozak <jk@noontide.demon.co.uk>.
2483 * strports.c, strports.h: Make scm_eval_0str return the value of
2484 the last expression evaluated (previously, it returned void).
2486 * strports.c, strports.h: New function: scm_read_0str. Does what
2489 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2491 * simpos.c (scm_getenv): return #f if string can't be found in the
2492 environment instead of throwing an exception, for compatibility
2493 with numerous other systems.
2495 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
2497 * Makefile.am (.c.x): Use guile-snarf.
2498 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
2500 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
2502 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
2504 * backtrace.c (scm_display_error_message): Made non-static, and
2505 renamed from display_error_message.
2506 * backtrace.h (scm_display_error_message): Added extern decl.
2507 * throw.c (uncaught_throw): Use it to display the error message.
2509 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
2511 * inet_aton.c: Use #if 0, not #ifdef 0.
2513 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
2515 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
2516 to convert the returned value.
2517 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
2518 the offset argument.
2520 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
2522 Add new interface to catch/throw, usable from C as well as
2524 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
2525 (scm_internal_catch): New function, replaces...
2526 (scm_catch_apply): Deleted.
2527 * throw.c (scm_catch_apply): Deleted; replaced with a more general
2528 mechanism which is a bit more code, but can be used nicely from C
2529 and implement the Scheme semantics as well.
2530 (scm_internal_catch): This is the replacement; it's named after
2531 the analogous function in Emacs.
2532 (scm_catch): Reimplemented in terms of the above.
2533 (struct catch_body_data, catch_body, catch_handler): New
2534 functions, used by scm_catch.
2535 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
2536 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
2537 support for new cwdr.
2539 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
2542 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
2544 * acconfig.h: Added DYNAMIC_LINKING symbol.
2545 * configure.in: Add option and checks for dynamic linking.
2546 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
2547 dynl.h: New files for dynamic linking support.
2548 * Makefile.am (libguile_a_SOURCES):
2550 (modinclude_HEADERS): Added "dynl.h".
2551 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
2553 * init.c (scm_boot_guile_1): Call
2554 scm_init_dynamic_linking to initialize dynamic linking support.
2556 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
2558 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
2559 (as we Schemers say). It needs to be global, so that I can tweak
2560 it for the proper operation of unexec.
2561 (scm_boot_guile_1_live): New variable, see above.
2563 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
2565 * guile-snarf.sh: Removed.
2566 * PLUGIN/guile.libs: Added dependency for -lm.
2567 * acinclude.m4: Renamed from aclocal.m4.
2568 * PLUGIN/greet: Removed.
2569 * Makefile.am, aclocal.m4: New files.
2570 * configure.in: Updated for Automake.
2572 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
2574 * eval.c (scm_definedp): Use top_level_lookup_closure_var
2575 and not top_level_lookup_thunk_var.
2577 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
2579 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
2581 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
2583 * eval.c (scm_definedp): Incompatibly changed to be a builtin
2584 Scheme function, instead of syntax. Single argument is now a
2587 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2589 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
2590 scm_ra_divide): Properly terminate statements passed as arguments
2591 to IVDEP macros. (Thanks to Bernard Urban.)
2593 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
2594 with non-constant sizes. (Thanks to Bernard Urban.)
2596 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
2598 It's an "eval closure", not an "eval thunk." A thunk is a
2599 function of no arguments.
2600 * root.h (struct scm_root_state): Renamed
2601 top_level_lookup_closure_var from top_level_lookup_thunk_var.
2602 (scm_top_level_lookup_closure_var): Renamed from
2603 scm_top_level_lookup_thunk_var.
2604 * root.c (mark_root): Uses changed.
2605 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
2606 * init.c (scm_start_stack): Uses changed.
2607 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
2608 Change scheme-visible name to *top-level-lookup-closure* from
2609 *top-level-lookup-thunk*.
2611 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
2613 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
2614 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
2616 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
2618 * gc.c (struct scm_heap_seg_data): Doc fixes.
2620 * gc.c (scm_gc_sweep): Empty all segments' freelists before
2621 sweeping. Then, prepend each segment's free cells to its
2622 freelist, rather than wiping out the old value. (Thanks to Marius
2625 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
2626 scm_check_freelist, scm_debug_newcell): New functions and
2627 variables, for debugging freelist problems.
2628 * pairs.h (SCM_NEWCELL): New debugging version added.
2629 * gc.h (scm_debug_newcell): Added extern declaration, used by
2630 debugging version of SCM_NEWCELL.
2632 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2634 On some systems <libc.h> conflicts with <unistd.h>, and should not
2635 be #included at all.
2636 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
2637 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
2638 * configure.in: Call it.
2639 * posix.c, filesys.c: Use its results to decide whether or not to
2641 * configure, scmconfig.h.in: Rebuilt with autoconf and
2644 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2646 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
2647 pointer to the stdio stream before calling scm_setbuf0, so the
2648 latter will be able to retrieve it. I'm surprised this didn't
2649 segfault earlier. (Thanks to Christopher Lee.)
2651 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2653 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
2656 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2658 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
2659 number of stack narrowing specifier pairs. The first specifier in
2660 a pair controls inner border, the second the outer border. A
2661 number means cut that number of frames, a procedure object means
2662 cut until that object is found in operator position in a frame.
2664 * root.c (cwdr): Bugfix.
2666 * read.c: Recording of positions disabled by default.
2668 * procs.c (scm_closure_p): New function.
2670 * posix.c (scm_tmpnam): New function.
2672 * load.c: Added #include "throw.h".
2673 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
2676 * load.c, load.h (scm_read_and_eval_x): New function.
2678 * eval.c: Renamed debug option "deval" to "debug".
2680 (scm_eval_x): `eval!' is no longer accessible from the scheme
2681 level. Motivation: We can't allow operations which introduce
2682 glocs into the scheme level. Guile's type system can't handle
2683 these as data. Use `eval' or `read-and-eval!' as replacement.
2685 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
2686 SCM_CONSP since this is a macro!; Set vframe.prev to
2687 scm_last_debug_frame instead of 0. In this way we can look
2688 "above" the virtual start stack frame if we wish.
2689 (scm_debug_hang): New function: Useful for debugging Guile in
2690 certain tricky situations. Will probably be removed later...
2692 * debug.h: Changed semantics of debug option "backtrace". This
2693 option now only indicates whether we want automatic backtrace at
2696 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2698 * ports.c: #include "filesys.h"
2699 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
2701 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
2702 Motivation: This is system specific code which is related to file
2703 I/O. It also may use select. Added code by Gary Houston to
2704 detect presence of character in stdio buffers.
2706 * libguile.h: #include "libguile/libpath.h"
2708 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
2709 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
2710 SCM_SITE_DIR; Install libpath.h among the other include files.
2712 * load.c, load.h (scm_sys_package_data_dir): New function.
2714 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2716 * stacks.h: Bugfix: Don't use tail-array length field as stack
2717 length field! This screwed GC.
2719 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2721 * _scm.h: Added #ifndef around definition of macros min and max.
2723 * __scm.h: Added hooks for threads to plugin to in ints protection
2724 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
2725 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
2726 the main code in these macros duplicated and spread over multiple
2727 files. Renamed SCM_THREADS_SWITCHING_CODE ->
2728 SCM_THREAD_SWITCHING_CODE.
2730 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
2732 * snarf.h: New file.
2733 * guile-snarf.sh: New file.
2734 * Makefile.in (inner_h_files): Added snarf.h
2735 (ancillary, install, uninstall, distclean): Added actions for
2737 (.c.x): Use guile-snarf.
2738 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
2739 (gen_c_files): Note that these depend on guile-snarf.
2740 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
2741 now in "snarf.h". Added #include "snarf.h" to get them.
2742 * libguile.h: Added #include "snarf.h".
2743 (Patches applied and tweaked by Jim Blandy.)
2745 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
2747 * socket.c: Use K&R style declaration for 'close'; the GNU coding
2748 standards suggest against providing prototypes for system
2749 functions. Thanks to Greg Troxel.
2751 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
2753 * strports.c (scm_eval_0str): New function.
2754 #include "read.h", to get prototype for scm_read.
2755 * Makefile.in (strports.o): Update dependencies.
2756 * strports.h: New prototype.
2758 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
2759 scheme name from "int?" to "integer?". It seems to do the job.
2760 * numbers.h: Rename prototype too.
2761 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
2764 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
2765 scm_num_eq_p): Rename these according to R4RS conventions: call
2766 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
2767 to making libguile R4RS compliant without ice-9...
2769 * load.c (scm_sys_search_load_path): Search for files under all
2770 extensions listed in the %load-extensions variable. If FILENAME
2771 is absolute, return it unchanged, without searching the load path.
2772 (scm_loc_load_extensions): New variable, pointing to
2773 %load-extensions' value cell.
2774 (scm_init_load): Initialize it, and the value it points to.
2775 (scm_primitive_load_path): Improve error reporting.
2777 * load.c (scm_loc_load_hook): New variable, pointing to value cell
2778 of new Scheme variable %load-hook.
2779 (scm_primitive_load): Apply %load-hook to filename.
2781 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
2783 * configure.in: add tests for figuring out whether buffered data
2784 is available in a FILE structure, which is needed by char-ready.
2786 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
2789 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
2790 exceptions using misc_error instead of syserror. It seems a bit
2791 odd to throw an exception if a string can't be found in the
2792 environment, but it's consistent with open-file, stat etc.
2793 (simpos.h): remove sys_ from getenv.
2795 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
2796 occurs, throw an error instead of returning errno. Return value
2798 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
2800 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
2802 * filesys.c (scm_stat2scm): derive file type and permissions from
2803 the stat mode and append them to the returned vector.
2804 There isn't much overhead in doing this and it avoids the need to
2805 work with S_IRUSR et al. in Scheme.
2806 Define symbols scm_sym_regular etc.
2807 (scm_init_filesys): don't intern S_IRUSR etc.
2809 * load.c: change s_try_load and s_try_load_path to s_primitive_load
2810 and s_primitive_load_path.
2812 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
2814 * error.h: don't declare error symbols. prototype for scm_misc_error.
2816 * stackchk.c (scm_stack_overflow_key): defined here instead of in
2819 * error.c: use SCM_SYMBOL to set up error keys.
2820 scm_misc_error: new procedure.
2822 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2824 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
2825 between `#!' and `!#' is ignored.
2826 (skip_scsh_block_comment): New function.
2828 * feature.c (scm_set_program_arguments): New argument, FIRST.
2829 * feature.h: Update prototype.
2830 * init.c (scm_boot_guile_1): Pass new argument to
2831 scm_set_program_arguments.
2833 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
2835 * init.c (scm_start_stack): Don't initialize scm_progargs here.
2836 (scm_boot_guile): Call scm_set_program_arguments here, later than
2837 the old initialization.
2839 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
2840 initialization procedure.
2841 - Delete in, out, err arguments; there are other perfectly good
2842 ways to override these when desired.
2843 - Delete result argument; this function shouldn't ever return.
2844 - Rename init_func argument to main_func, for less confusion.
2845 - Delete boot_cmd argument; main_func is more general.
2846 -Add 'closure' argument, to help people pass data to main_func
2847 without resorting to global variables.
2848 - Abort if reentered; don't bother returning an error code.
2849 - Call scm_init_standard_ports to set up the default/current
2850 standard ports; no need to pass them to scm_start_stack.
2851 - Remove code to evaluate the boot_cmd, and start the repl; let
2852 the user do something like that in main_func if they want.
2853 - Remove code to package up a return value; main_func can do any
2855 - Call exit (0), instead of returning.
2856 (scm_start_stack): Don't initialize the I/O ports here; that's
2857 weird. Delete in, out, err arguments. Move guts to
2858 scm_init_standard_ports, scm_stdio_to_port.
2859 (scm_init_standard_ports): New function, to set up current and
2860 default standard ports.
2861 (scm_start_stack, scm_restart_stack): Make these static.
2862 * init.h (scm_boot_guile): Adjust declaration.
2863 (scm_start_stack, scm_restart_stack): Remove externally
2864 visible declarations for these.
2865 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
2867 * fports.c (scm_stdio_to_port): New function. Its guts used to be
2868 written out several times in scm_start_stack.
2869 * fports.h: New declaration for the above.
2871 * feature.c (scm_set_program_arguments): New function.
2872 * feature.h: New declaration for the above.
2874 * ports.c: Formatting tweak.
2876 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
2878 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
2879 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
2880 for obtaining the address of a car or cdr field. Motivation:
2881 &SCM_CXR make assumptions about the internal structure of the
2884 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
2885 Motivation: see SCM_CXRLOC.
2887 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
2888 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
2889 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
2890 Motivation: Safer use. Some other macros are defined in terms of
2891 these operations. If these are defined using the SCM_SETCXR
2892 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
2893 to inefficiency and an <e1> with side-effects could potentially
2894 break. Also, these particular operations are heavily utilized in
2895 the garbage collector. In unoptimized code there will be a
2898 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
2899 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
2900 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
2901 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
2902 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
2903 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
2904 vports.c: Cleaned up use of pairs: Don't make any special
2905 assumptions about the internal structure of selectors and
2906 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
2907 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
2908 (Among other things, this change makes it easier to build Guile
2909 with certain compilers which have problems with casted lvalues.)
2911 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2913 * stacks.c: Improve selection of relevant stack frames when making
2914 a stack object. Introduce one level of indirection in the stack
2915 object to make it possible to "narrow" to a certain region of the
2916 stack. This facilitates making use of more clever algorithms (not
2917 implemented) for selecting relevant frames and gives a cleaner
2918 design since selection of frames can be done independently of
2919 extraction of frames from the real stack.
2920 (scm_stack_id): Also take #t as argument which means look at
2923 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
2924 Turn n_tail into an integer directly representing current number
2925 of frames in stack. Add field tail.
2927 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
2929 * debug.c (scm_make_memoized): Made it available at scheme level.
2930 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
2931 SCM_NIMP before applying heavier predicates in argument checking.
2932 (scm_local_eval): Also take memoized object as argument.
2934 * backtrace.c (scm_display_error): Just a safety measure: Stacks
2935 aren't created with zero length, but should such a strange
2936 creature suddenly turn up...
2938 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
2940 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
2941 `del', for the sake of C++ compilers. (Patch applied by JimB.)
2943 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
2945 * variable.c (scm_make_variable): Make the name hint optional, as
2947 (anonymous_variable_sym): Renamed from variable_sym. All uses
2950 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
2951 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
2952 of scm_primitive_load_path was also changed to
2953 "primitive-load-path", from "%try-load-path". Callers changed.
2954 We'd like to respect the convention that a function named
2955 "try-mumble" should behave just like the function called "mumble",
2956 but return #f instead of signalling some error.
2957 * load.h: Rename prototypes.
2959 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2961 * print.c (make_print_state, grow_print_state), print.h: Modified
2962 the print state representation: Don't use a tail array for
2963 recording of circular references. Resizing of the print state
2964 structure invalidates the print state pointer. To avoid passing
2965 around an indirect print state reference to all printing
2966 functions, we instead let the print state reference a resizable
2969 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2971 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
2972 Don't crash when passed an improper list terminated by a
2973 non-immediate value.
2975 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
2977 Allocate data for structures on an eight-byte boundary, as
2978 required by the tagging system.
2979 * struct.c (alloc_struct): New function.
2980 (scm_make_struct, scm_make_vtable_vtable): Call it.
2981 * struct.h (scm_struct_n_extra_words): Bump to 3.
2982 (scm_struct_i_ptr): New "field".
2983 * gc.c (scm_gc_sweep): When we need to free the data, use the
2984 information stored by alloc_struct to find the beginning of the
2985 block allocated to the structure, so we can free it.
2987 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2989 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
2992 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
2993 (scm_debug_info): New member: id.
2995 * stacks.c: Stacks are now represented as structs; Stacks have an
2996 id given to them by `start-stack'.
2997 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
2999 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
3000 Changed stack representation.
3002 * debug.c (scm_procedure_name): Try procedure property `name' for
3003 compiled closures aswell.
3005 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
3007 * eval.c: scm_i_name moved to gsubr.c
3008 (scm_m_define): Record names of all kinds of procedure
3009 objects. (Earlier, only closures were recorded.)
3011 * procprop.h: Added declaration of scm_i_name.
3013 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
3014 (scm_make_gsubr): Record names of compiled closures.
3016 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3018 * debug.c, debug.h: Removed obsolete code.
3020 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
3021 stacks.c: Renamed regs --> scm_contregs.
3023 * print.c (scm_free_print_state): Cleanup print state before
3024 returning it to pool. It is better to do it here than in
3025 scm_prin1 since scm_prin1 is called often.
3027 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
3028 s_set_source_property_x): Check that first argument is a pair or a
3031 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
3032 scm_i_line, scm_i_column and scm_i_breakpoint global.
3034 * init.c: Added #include "backtrace.h" and #include "stacks.h".
3035 (scm_boot_guile_1): Added calls to scm_init_backtrace and
3038 * debug.h: Added debug object smob declaration and macro
3041 * configure.in: Build with backtrace.o and stacks.o if debug
3044 * Makefile.in: Added entries for new files: backtrace.c,
3045 backtrace.h, stacks.c and stacks.h.
3047 * symbols.c (scm_sym2ovcell): Fixed documentation.
3049 * _scm.h (min, max): Added.
3051 * async.c: Moved `min' macro to _scm.h.
3053 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
3054 SCM_BACKTRACE_INDENT.
3056 * eval.c: Added new debug options `maxdepth' and `indent'.
3058 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
3060 * print.h: Added selector SCM_PRINT_STATE.
3062 * print.c: New functions: scm_make_print_state,
3063 scm_free_print_state.
3065 * print.h: Added declarations for scm_make_print_state,
3066 scm_free_print_state.
3068 * debug.c (scm_m_start_stack): New acro.
3070 * debug.h: Small cleanup.
3072 * init.c (scm_boot_guile_1): Moved scm_init_debug below
3075 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

3095 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,

3097 declare functions with prototypes. (Patch thanks to Marius
3100 More prototype-related changes from Marius Vollmer:
3101 * gdb_interface.h: Wrapped header file in #ifdef/#endif
3102 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
3103 * ports.h (ptobfuns): Added prototypes. This means some casting in
3105 * fports.c: Added casts for initializations, since the functions
3106 are defined to take FILE * as their stream argument, not SCM.
3107 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
3108 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
3109 to `char *str_data' to conform to prototype.
3111 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
3113 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
3115 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
3117 * stime.c, stime.h: use SCM_P method.
3119 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
3121 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
3122 be given at least two arguments. Insist that lst's last element
3123 be a list, but don't make any requirements of its predecessors.
3125 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
3127 * eval.c (scm_nconc2last): Revert last change; there seems to be
3128 other stuff going on here.
3130 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
3132 * eval.c (scm_nconc2last): Make sure that each element of lst
3133 (which is a list of argument lists, except for the tail) is a
3134 proper list, i.e., finite and terminated by '().
3136 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3138 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
3141 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
3142 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
3145 * vectors.c (scm_make_vector): Fill vectors with the undefined
3146 value, to help make Guile Scheme code more portable to other
3149 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
3150 * symbols.h, tags.h: Doc fixes.
3152 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
3154 * async.c (scm_take_signal): Doc fixes.
3156 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
3158 * numbers.c (scm_divbigint): When the remainder is zero, we don't
3159 want to subtract it from the modulus; we just want to leave it
3162 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
3164 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
3167 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
3169 * throw.c (scm_catch_apply): Finished implementation of
3172 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
3174 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
3176 (scm_init_filesys): set "i/o-extensions" feature.
3179 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
3181 * Makefile.in (root.o): Correct dependencies.
3183 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
3185 * Makefile.in: Added dependency entry for root.o.
3187 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
3188 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
3190 * init.c (scm_start_stack): Set initial root continuation number
3193 * procs.c: New function: scm_thunk_p.
3195 * procs.h: Added declarations of scm_thunk_p.
3197 * root.c: Renamed `call-with-new-root' -->
3198 `call-with-dynamic-root'.
3199 (cwdr): Removed allocation of new root state. This should be done
3200 separately by use of scm_make_root.
3201 (scm_apply_with_dynamic_root): New function: Does what it
3202 sounds like. Needed when spawning threads.
3204 * root.h: Added member last_debug_frame to root state.
3205 Added #include "libguile/debug.h"
3207 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
3208 arguments. The motivation is that code in root.c needs catch
3209 functionality, and we want to avoid code duplication.
3210 New functions: scm_catch, scm_lazy_catch. These are wrappers for
3211 scm_catch_apply. scm_lazy_catch is intended to introduce catch
3212 handlers that run without popping the stack into the dynwind
3215 * throw.h: Added prototypes for scm_catch_apply and
3218 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3220 * root.h (scm_root, scm_set_root): Decouple thread support details
3221 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
3222 SCM_SET_THREAD_LOCAL_DATA.
3224 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
3225 and tortoise scanning loop.
3227 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
3229 * Makefile.in: Rebuild dependencies.
3231 * libguile.h: #include "libguile/print.h" before "smob.h", since
3232 the latter uses the print_state structure.
3234 * throw.c (scm_ithrow): Use the correct variable when checking to
3235 see if a given element of scm_dynwinds is a valid catch.
3237 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
3238 structure, abort; don't just silently ignore the garbage.
3240 * _scm.h: #include "print.h" here, since it seems to be used just
3242 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
3243 strports.c, unif.h: Don't #include "print.h".
3245 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3247 * feature.h (scm_loc_features): Removed external declaration.
3248 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
3250 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3252 * feature.c (scm_init_feature): Added threads feature (needs to be
3253 initialized here, since features doesn't exist when
3254 scm_init_threads is called).
3256 * libguile.h: Added #include "libguile/../threads/threads.h".
3257 (This is a kludge to get thread support working. This should be
3260 * configure.in, acconfig.h: Added flags for thread support.
3262 * scmsigs.c: Define `signal' to be `pthread_signal' if using
3265 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
3266 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
3269 * _scm.h: Added conditional #include "threads.h"
3271 * __scm.h (SCM_ASYNC_TICK): Added call to macro
3272 SCM_THREADS_SWITCHING_CODE.
3274 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
3275 allocate the basic dynamic root object.
3276 (scm_boot_guile): Added call to scm_init_root.
3278 * root.c, root.h: Added root smob.
3279 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
3280 functions: Implements dynamic roots mostly according to spec in
3281 SCM manual. Main difference is that the second argument is a
3282 throw handler rather than an error "thunk".
3284 * root.h: Added declaration of scm_init_root.
3286 * root.c: Added #include "genio.h", #include "smob.h", #include
3287 "pairs.h", #include "throw.h", #include "dynwind.h", #include
3289 (scm_init_root): Added #include "root.x".
3291 * throw.c: Added #include "stackchk.h"
3292 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
3293 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
3294 can be used in scm_call_with_new_root; Added reenabling of stack
3295 checking when catching a throw.
3297 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
3299 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
3301 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
3302 element is not found, as per R4RS.
3304 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
3306 * list.c: Doc fixes throughout.
3308 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3310 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
3311 declare the char * to be const. Avoids a warning in rgx.c.
3313 * ports.h: spelling fix.
3315 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
3318 * load.c (scm_sys_try_load_path): throw an error if file not found
3319 (like it says it in NEWS).
3321 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
3323 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
3324 PROPS slot to '(), not #f; it's an empty alist.
3326 * throw.h, throw.c: Use SCM_P instead of #if hair.
3328 Remove special support for uncaught throws; see throw.c for
3330 * throw.c (uncaught_throw): New function.
3331 (scm_ithrow): Call uncaught_throw if we don't find a throw
3332 target; don't mess with scm_bad_throw_vcell.
3333 (scm_bad_throw_vcell): Variable deleted.
3334 (scm_init_throw): Don't initialize it.
3336 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
3339 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3341 * numbers.c (scm_istr2int): If the number is short (as most
3342 numbers are), just call scm_small_istr2int to deal with it.
3343 (scm_small_istr2int): New function, created by un-#ifdefing the
3344 non-bignum version of scm_istr2int and renaming it.
3346 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
3348 * load.c (scm_sys_try_load): don't check whether value returned
3349 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
3350 Change the Scheme name from %try-load to primitive-load.
3352 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
3353 Can avoid passing a message, allowing it to be derived in the
3354 error handler (e.g., if we want to throw to the key both from
3357 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
3359 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
3360 references now have a new appearance which is more compact and
3361 also gives a clue about what the target of the reference is.
3362 By setting parameters in the print state, more fancy printing can
3363 be achieved. This is used by the (not yet commited) backtrace
3366 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
3368 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
3371 * print.c: Added #include "struct.h". Removed function
3374 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
3375 scm_iprin1. Removed prototype for scm_prlist.
3377 * arbiters.c (prinarb),
3378 async.c (print_async),
3379 debug.c (prindebugobj, prinmemoized),
3380 eval.c (prinprom, prinmacro),
3381 filesys.c (scm_fd_print, scm_dir_print),
3383 mallocs.c (prinmalloc),
3384 numbers.c, numbers.h (scm_floprint, scm_bigprint),
3385 smob.h (scm_smobfuns),
3386 srcprop.c (prinsrcprops),
3388 unif.c, unif.h (scm_raprin1, rapr1),
3389 variable.c (prin_var): Changed argument `int writing' to
3390 `scm_print_state *pstate'.
3392 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
3393 that it will be called before scm_init_print.
3395 * print.c (scm_prin1): Print states are now allocated when calling
3396 scm_prin1 and then passed around to all printing functions as an
3397 argument. A cache `print_state_pool' enables reuse of print
3399 (scm_make_print_state): New function.
3400 (scm_iprin1): Adaption to print states.
3401 (scm_iprlist): An initial "hare and tortoise" scan brings down
3402 time complexity to O (depth * N). (Better time complexity will be
3403 achieved when the printing code is completely rewritten.)
3405 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3407 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
3408 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
3409 it gets done whether or not the cache variable has a value.
3411 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3413 Distinguish #f and ().
3414 * __scm.h: #undef SICP.
3415 * pairs.h (SCM_EOL): Delete this definition, equating it with
3417 * tags.h (SCM_EOL): Give it a new definition here; I think I found
3418 the value it used to have. Doc fixes, too.
3420 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
3422 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
3423 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
3424 Lord's implementation of structs, allowing for tail arrays as
3425 described in the manual. Also fixed some bugs. (Both the interface
3426 and the implementation should be improved.)
3428 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
3430 * print.c, print.h: Closures now print like #<procedure foo (x)>.
3431 People who whish to see the source can do `(print-enable 'source)'.
3432 Removed #ifdef DEBUG_EXTENSIONS.
3434 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
3436 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
3437 integer (assuming for now accepting an integer is a good thing).
3439 * error.c, fports.c: replace use of %S in lgh_error args with %s.
3440 %S will be used instead for write'ing arguments.
3442 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
3443 asserts. fix a few other asserts.
3444 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
3445 scm_uniform_vector_ref, scm_array_set_x,
3446 scm_dimensions_to_unform_array): change args in
3447 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
3448 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
3449 scm_substring_fill_x): likewise.
3450 gsubr.c (scm_gsubr_apply): likewise.
3451 eval.c (SCM_APPLY): likewise.
3453 * eval.c (4 places): replace scm_everr with lgh_error or
3456 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
3457 scm_memory_error): new procedures.
3458 scm_everr: deleted. can use scm_wta, dropping first two args.
3459 scm_error: convert NULL subr to SCM_BOOL_F.
3461 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
3464 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
3467 * error.c, error.h: new error keys: scm_arg_type_key,
3468 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
3470 scm_wta: reimplement using lgh_error instead of scm_everr.
3472 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
3474 * gdbint.c: scm_lread now has one more argument.
3476 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
3477 scm_port_\1; Added mutator scm_set_port_filename_x (used when
3478 loading source from non-file ports, which, e. g., happens when
3479 using the Emacs interface).
3481 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
3484 * read.c: Added code for recording of positions of source code
3485 expressions; New functions: recsexpr, scm_lreadrecparen;
3486 _scm_make_srcprops --> scm_make_srcprops
3487 (scm_flush_ws): Removed updating of positions counters. This work
3488 is already done by scm_gen_getc
3490 * read.h: Added prototype for scm_lreadrecparen
3492 * print.c: Added #include "alist.h"
3494 * eval.c: Added #include "hash.h"
3496 * eq.c: Added #include "ramap.h"
3498 * options.c: Documentation fixes.
3500 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
3501 (scm_init_srcprop): Adjusted size of initial source-whash. Name
3502 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
3503 --> scm_make_srcprops
3505 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
3506 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
3507 function calls in the definition of the whash access macros.
3509 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
3511 * init.c (scm_boot_guile): Add level of indirection to
3512 scm_boot_guile_1() to ensure that stack base pointer is properly
3513 initialized. There was no guarantee that variable i was the
3514 highest/lowest variable on stack (i.e. the call frame of
3515 scm_boot_guile was not completely protected from gc).
3517 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
3519 * ports.h (scm_port_table): put back file_name, it will be used to
3520 support debugging. Undo related changes in fports.c, ioext.c,
3523 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
3525 * ports.h (scm_port_table): remove file_name member for now, it seems
3527 * fports.c (scm_open_file): don't set file_name in PTAB.
3528 (prinfport): don't use file_name in PTAB.
3529 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
3530 * ports.c (scm_add_to_port_table): don't intialize file_name.
3531 (scm_port_file_name): remove for now.
3532 * gc.c (scm_gc_mark): don't mark PTAB file_name.
3534 * fports.h (scm_mkfile): prototype deleted.
3535 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
3537 * debug.c, unif.c: use scm_out_of_range instead of
3538 wta for range errors (ASSERT still needs work).
3540 * error.c, error.h (scm_out_of_range): new procedure.
3542 * error.c, error.h (scm_out_of_range_key): new key.
3544 * posix.c (scm_sync): #else was missing.
3546 * error.c, error.h: append _key to names scm_num_overflow and
3549 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
3550 of consing an empty list.
3551 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
3552 of macros, saves code and string space.
3553 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
3554 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
3555 lower case. Rename scm_syserror_m to scm_syserror_msg.
3556 error.h: prototypes for new procedures.
3558 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
3560 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
3562 * error.c, error.h: setup scm_num_overflow key.
3564 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
3565 Remove definition of SCM_OVSCM_FLOW.
3567 * fports.c (scm_open_file): use SCM_SYSERROR_M.
3569 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
3570 explicit message and args.
3572 * error.c, error.h, __scm.h: change system_error_sym to
3575 * error.c (system_error_sym): remove leading %% from the Scheme name
3578 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
3580 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3582 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
3583 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
3584 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
3585 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
3586 renamed. (These were introduced by unsupervised name
3589 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3591 * print.c: Added code for detection of circular references during
3592 printing. (init_ref_stack, grow_ref_stack): New functions. Added
3593 a hook for printing of closures (accessible via print options).
3594 This leads to a split of calls to scm_iprin1 into two classes:
3595 elementary print operations (e. g. the code which prints a smob)
3596 still use scm_iprin1 while top level calls (like scm_display) use
3597 scm_prin1. scm_prin1 begins by clearing the data structure used
3598 to record reference information.
3600 * print.h: Added declarations of scm_prin1 and scm_prlist.
3602 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
3604 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
3606 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
3608 * error.c (err_head): scm_iprin1 --> scm_prin1
3610 * debug.c: Adjusted header comment.
3614 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
3616 * strerror.c: Doc fix.
3618 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3620 * gdbint.c (gdb_read): Now possible to run during GC.
3621 (unmark_port, remark_port): New functions.
3623 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
3625 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
3626 of allocating a new string object. Also, increase size by
3627 the factor 2 instead of 1.5.
3629 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
3631 * __scm.h (SCM_P): Corrected to run under traditional C.
3633 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
3636 * async.c: Calls to scm_sysintern corrected.
3638 * async.h (scm_async_clock): Redundant declaration removed.
3640 * continuations.c (scm_dynthrow): Redundant declaration removed.
3642 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
3643 Definition typos corrected.
3645 * debug.h: Missing declarations of functions in debug.c added
3648 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
3649 Missing declarations to functions in eval.c added.
3651 * filesys.c: Possibly uninitialized variable rv.
3653 * gc.h (scm_object_addr, scm_unhash_name): Missing
3654 declarations of functions defined in gc.c added.
3656 * genio.c: Possible typos str_data -> wstr_data. ???
3658 * genio.c: Possibly unintended shadowing of local variable
3659 `int c' (gotos out of scope of inner `c'). ???
3661 * init.c: Uninitialized `SCM last' may be used.
3663 * ioext.h: (scm_sys_isatty_p): Typo.
3665 * list.h (scm_list_head): Missing prototype for function in
3668 * numbers.c (scm_two_doubles): Changed from extern to static
3669 (is used only within numbers.c).
3671 * numbers.h: Repeated declarations removed.
3673 * ports.h (scm_close_all_ports_except): Declaration for the
3674 function defined in ports.c added.
3676 * posix.h: Missing declarations added.
3678 * procs.h (scm_make_subr_opt): Missing declaration added.
3680 * socket.h (scm_sys_gethost): Missing declaration added.
3682 * socket.h: Redundant declarations removed (they are in fdsocket.h).
3684 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
3685 Missing declarations added.
3687 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
3689 * struct.c: Uninitialized variable `SCM answer' may be used.
3691 * unif.c (l2ra): Declaration prototype.
3693 * unif.c (scm_array_equal_p): Dummy definition removed (it is
3694 defined in ramap.c).
3696 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
3697 Redundant declarations removed (they are in ramap.h).
3699 * variable.h (scm_make_udvariable,
3700 scm_make_undefined_variable): Declaration corrected to
3701 correspond variable.c.
3703 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
3704 Missing declarations added.
3706 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
3708 * Makefile.in (distclean): Don't forget to delete fd.h.
3710 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3712 * fd.h.in, tags.h: Trivial cleanups.
3714 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
3715 marksweep.h just declared functions from gc.c.
3716 * gc.h, libguile.h: Don't #include "marksweep.h".
3717 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
3718 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
3719 dependencies updated.
3721 * libguile.h: Don't #include "files.h"; it's been deleted.
3723 * files.c (scm_sys_delete_file): Moved to filesys.c.
3724 File is now empty; deleted.
3726 * filesys.c: scm_sys_delete_file is now here. Remove
3727 #if's; they seem to rely on remnants of an old portability
3728 regimen. If the problems come up again, solve them properly,
3729 using autoconf. Specifically: Don't test M_SYSV, and #define
3730 remove to be unlink if it's #defined; don't use remove just
3731 because HAVE_STDC_HEADERS is #defined.
3732 * filesys.h: Add declarations for scm_sys_delete_file.
3733 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
3734 files.o, files.h, files.c, and files.x.
3735 * init.c: Don't #include "files.h", and don't call scm_init_files.
3737 Use SCM_P instead of PROTO; the latter intrudes on the user's
3739 * params.h: Deleted; definition of SCM_P moved to...
3740 * __scm.h: ... here, where it replaces PROTO macro.
3741 * libguile.h, smob.h: Don't #include "params.h".
3742 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
3743 smob.h: Fix prototypes accordingly.
3744 * Makefile.in: Update dependencies.
3745 (inner_h_files): Remove params.h.
3747 * gc.c: #include "gc.h"; every module should include its header,
3748 to let the compiler cross-check the declarations against the
3751 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
3752 simpos.h: #include "libguile/__scm.h".
3754 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
3756 * init.c: Don't forget to #include smob.h and init.h.
3757 * Makefile.in: Dependencies updated.
3759 * smob.h: Use PROTO instead of #if __STDC__.
3761 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
3763 * __scm.h: Doc fixes.
3765 * __scm.h, libguile.h: Use "quotes" in the #includes, not
3766 <angles>; this allows `make depends' to work properly.
3768 * libguile.h: #include smob.h and pairs.h before the others; they
3769 define typedefs used by other headers.
3771 C files should #include only the header files they need, not
3772 libguile.h (which #includes all the header files); the pointless
3773 recompilation was wasting my time.
3774 * Makefile.in (all .o dependency lists): Regenerated.
3775 * libguile.h: Don't try to get a definition for size_t here...
3776 * __scm.h: Do it here.
3777 * _scm.h: Since this is the internal libguile header, put things
3778 here that all (or a majority) of the libguile files will want.
3779 Don't #include <libguile.h> here; that generates dependencies on
3780 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
3781 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
3782 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and
3784 * alist.c: Get "eq.h", "list.h", "alist.h".

3798 * error.c: Get "error.h", "throw.h", "genio.h", "pairs.h".

3803 * fdsocket.c: Get "fdsocket.h", "unif.h", "filesys.h".
3804 * feature.c: Get "feature.h".
3805 * files.c: Get "files.h".
3806 * filesys.c: Get "filesys.h", "smob.h", "genio.h".
3807 * fports.c: Get "fports.h", "markers.h".

3816 * init.c: Get everyone who has an scm_init_mumble function:
3817 "weaks.h", "vports.h", "version.h", "vectors.h", "variable.h",
3818 "unif.h", "throw.h", "tag.h", "symbols.h", "struct.h",

3883 * print.h, read.h: #include "options.h", since everyone who uses
3884 either of these files will need that.
3886 * smob.h: #include "ports.h", "genio.h", and "print.h", since
3887 anyone who uses this file will need them to define the smob
3888 printing functions. Also, get markers.h, since people will need
3889 to #define the mark functions.
3891 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
3892 * ports.h: ... to here.
3894 * ports.h (scm_port_table_size): Explicitly give type as 'int';
3895 don't rely on archaic C default type rules.
3897 * fports.h: #include "libguile/ports.h", since you need that in
3898 order to parse this.
3900 * genio.h: #include "libguile/print.h", because you need that to
3901 parse this; don't bother #including "ports.h", since print.h gets
3904 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
3906 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
3907 this; it's now a reference to an element of *scm_root.
3909 * debug.h: Don't #include "options.h"; the compiler won't be able
3910 to find that once the headers are installed; instead, #include
3911 "libguile/options.h".
3912 * gc.h: Same, with marksweep.h.

3914 * scmhob.h: Same, with _scm.h.
3915 * smob.h: Same, with params.h.
3917 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
3918 C files; there's no need for this, and it forces recompilations
3921 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
3923 * error.c (scm_error): declare scm_error_callback.
3925 * error.h: prototype for scm_error_callback.
3927 * __scm.h: define lgh_error.
3928 (SCM_SYSERROR): redefine using lgh_error.
3930 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
3932 * error.c (scm_error): new procedure.
3934 * error.h: prototype for scm_error.
3936 * Makefile.in (install): install scmconfig.h from the current
3937 directory, not $(srcdir).
3939 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
3941 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3942 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3943 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

3949 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3950 vports.h, weaks.h: #include "libguile/__scm.h", not
3951 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
3952 dependencies are within libguile properly.
3954 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
3956 * Makefile.in (.c.x): Simplify; there's no need to run this rule
3957 when scmconfig.h doesn't exist.
3959 * load.c (scm_sys_try_load): Correct spelling.
3961 * feature.c (scm_loc_features): Make this static.
3963 * Makefile.in (libpath.h): Omit trailing slash from path. We
3964 shouldn't require it of users, so why put it here?
3966 Move code to initialize and search %load-path from ice-9 to C
3967 code, so we can use the load-path to find the ice-9 boot code;
3968 this makes it easier to run Guile without installing it. See
3969 corresponding changes in guile/Makefile.in.
3970 * feature.c: Move stuff concerned with the load path to load.c.
3971 (scm_compiled_library_path): Deleted.
3972 Don't #include libpath.h here.
3973 * feature.h: Don't mention scm_compiled_library_path.
3974 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
3975 <sys/stat.h>, and <unistd.h> (if present).
3976 (R_OK): #define if the system hasn't deigned to.
3977 (scm_loc_load_path): New variable.
3978 (scm_init_load_path, scm_sys_search_load_path,
3979 scm_sys_try_load_path): New functions.
3980 (scm_init_load): Initialize scm_loc_load_path to point to the
3981 value cell of the Scheme %load-path variable.
3982 * load.h: Add declarations for scm_sys_search_load_path,
3983 scm_sys_try_load_path.
3984 * init.c: Call scm_init_load_path.
3985 * Makefile.in (feature.o, load.o): Dependencies updated.
3987 * load.c, load.h: Rewrite using PROTO macro.
3989 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3991 * gc.c (scm_cellp): New function: C predicate to determine if an
3992 SCM value can be regarded as a pointer to a cell on the heap.
3994 * gc.h: Added declaration of scm_cellp.
3996 * gdb_interface.h: New file: The GDB interface header from the GDB
3999 * gdbint.c: New file: GDB interface.
4001 * gdbint.h: New file: GDB interface.
4003 * libguile.h: Added #include <libguile/gdbint.h>.
4005 * init.c (scm_boot_guile): Added scm_init_gdbint.
4007 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
4008 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
4009 found if object files and source are kept separate).
4011 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
4013 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
4015 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
4017 * configure.in: Don't substitute the values of TCL_SRC_DIR and
4018 TK_SRC_DIR; they're not relevant any more.
4020 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
4021 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
4023 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
4025 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
4026 search path, so we can find the <libguile/MUMBLE.h> headers.
4028 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
4030 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
4031 implicit in the .c.o rule.
4032 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
4035 Put the library path in a header file, instead of passing it on
4036 the command line in every compilation.
4037 * Makefile.in (libpath.h): New target.
4038 (feature.o): Depend on libpath.h.
4039 (clean): Delete libpath.h.
4040 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
4041 * feature.c: ... #include "libpath.h" here.
4042 * .cvsignore: Ignore libpath.h.
4044 Don't install the unwashed masses of Guile header files in the
4045 main #include path; put most of them in a subdirectory called
4046 'libguile'. This avoids naming conflicts between Guile header
4047 files and system header files (of which there were a few).
4048 * Makefile.in (pkgincludedir): Deleted.
4049 (innerincludedir): New variable; this and $(includedir) are enough.
4050 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
4051 (installed_h_files): Divide this up. Now this variable lists
4052 those header files which should go into $(includedir) (i.e. appear
4053 directly in the #include path), and ...
4054 (inner_h_files): ... this new variable says which files appear in
4055 a subdirectory, and are referred to as <libguile/mumble.h>.
4056 (h_files): List them both.
4057 (install): Create innerincludedir, not pkgincludedir. Put
4058 the installed_h_files and inner_h_files in their proper places.
4059 (uninstall): Corresponding changes.
4060 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
4061 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
4062 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
4063 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,

4066 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
4067 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
4068 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
4069 vports.h, weaks.h: Find __scm.h in its new location.
4070 * __scm.h: Find scmconfig.h and tags.h in their new locations
4071 (they're both "inner" files).
4073 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
4075 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
4077 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4079 * posix.c: Doc fixes.
4081 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
4083 * socket.c: Don't include a prototype for inet_aton; just use a
4084 K&R style declaration, to avoid warnings but minimize the chance
4085 of conflicts with the system.
4087 On NextStep, <utime.h> doesn't define struct utime, unless we
4088 #define _POSIX_SOURCE before #including it.
4089 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
4090 * acconfig.h: New comment text for above CPP symbol.
4091 * configure.in: Call it.
4092 * posix.c: #define _POSIX_SOURCE if it seems necessary.
4094 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
4096 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
4097 testing for __EMX__.
4099 * posix.c: #include <libc.h>, if it exists.
4101 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
4102 don't even know if the latter exists.
4104 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
4105 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
4106 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
4108 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
4110 (scm_init_posix): Use them when initializing the Scheme constants
4113 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4115 * Makefile.in (libdir, includedir, bindir): Use the
4116 autoconf-supplied values, instead of deriving them ourselves.
4117 (pkgincludedir, datadir, pkgdatadir): New variables.
4118 (install, uninstall): Put the header files in a special
4119 subdirectory, not in the main search path.
4121 * Makefile.in (ALL_CFLAGS): Provide the proper value for
4122 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
4124 * Makefile.in (IMPLPATH): Deleted; never used.
4126 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
4127 on the Tcl/Tk source any more.
4128 (INCLUDE_CFLAGS): Remove references to the above.
4130 * Makefile.in (version.o): Corrected dependencies.
4132 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
4134 * libguile.h: #include "version.h"
4136 * init.c (scm_boot_guile): Call scm_init_version.
4137 * gscm.c (gscm_run_scm): Call scm_init_version.
4139 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
4140 GUILE_VERSION): AC_DEFINE these.
4141 (acconfig.h): #undef the above symbols.
4143 * Makefile.in (libobjs): Add version.o.
4144 (installed_h_files): Add version.h.
4145 (c_files): Add version.c.
4146 (gen_c_files): Add version.x.
4147 (version.o): New rule.
4148 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
4149 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

4158 weaks.o): Add version.h to dependency lists.
4159 (markers.o): Remove duplicate rule.
4161 * version.h: New file.
4163 * version.c: New file.
4165 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4167 * symbols.c (scm_strhash): scm_downcase is now a function, not an
4168 array; use it appropriately. Since GCC is quite happy to
4169 subscript functions, it never warned us about this; we should use
4170 -Wpointer-arith in the future. I guess we never tested
4173 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
4175 * socket.c: Doc and copyright fixes.
4177 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4179 * debug.c: Fixed and improved gdb support.
4181 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4183 * socket.c: Added declaration of inet_aton to avoid compiler
4184 warning. (Hope this solution is correct.)
4186 * stime.c: Added declaration of ftime. (This is missing in
4189 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
4191 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
4193 * Makefile.in (c_files): add strerror.c.
4195 * strerror.c: new file from Emacs' sysdep.c.
4196 maybe configure should also check for sys_errlist.
4198 * configure.in (AC_REPLACE_FUNCS): add strerror.
4200 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4202 * debug.c (scm_init_debug): Added initialization for
4203 scm_evaluator_traps.
4205 * debug.h, debug.c: Various name changes.
4206 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
4207 "debug-options-interface". See commentary in options.c.
4209 * options.h, options.c: Options now have documentation strings.
4210 Also added a long explanatory commentary.
4212 * eval.c, print.h, print.c, read.h, read.c: Modifications to
4215 * gscm.c, init.c, root.c, throw.c: Bug fixes:
4216 last_debug_info_frame is now updated in all cases.
4218 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
4221 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4223 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
4224 Added option STACK_CHECKING.
4226 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4228 * Makefile.in: Added {debug,options,srcprop}.{h,c}
4230 * __scm.h: Removed symbols for debugging support.
4232 * acconfig.h: Added symbols for debugging support.
4234 * configure.in: Added user option for debugging support.
4235 --enable-debug will include the debugging code into libguile.a.
4237 * continuations.c (scm_make_cont): Enlarged the #if 0 around
4238 scm_relocate_chunk_to_heap.
4240 * debug.c: New file: low-level debugging support. It also
4241 includes support for debugging with gdb. (The extensions to gdb
4242 are written by Per Bothner at Cygnus.)
4244 * debug.h: New file: low-level debugging support.
4246 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
4247 argument pairs. Extensive modifications to the debugging
4248 evaluator. Added "SECTION:" commentaries to clarify what happens
4249 when, during double compilation. Renamed EVALIMP --> EVALIM.
4250 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
4251 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
4252 the beginning of the file. New procedure: scm_unmemocopy.
4253 Added some global state variables needed by the debugging
4254 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
4255 check_entry, check_apply, check_exit, debug_options and
4256 evaluator_traps. New acro: undefine.
4258 * eval.h: Renamed EVAL --> XEVAL.
4260 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
4261 --> scm_make_weak_key_hash_table.
4263 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
4264 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
4266 * libguile.h: Conditionally include debug.h
4268 * objprop.c (scm_object_properties, scm_set_object_properties_x):
4269 scm_object_properties shouldn't return handle. `handle' now gets
4270 initialized in scm_set_object_properties_x. scm_object_properties
4271 doesn't any longer create an entry in scm_object_whash.
4273 * options.c: New file: handling of run time options.
4275 * options.h: New file: handling of run time options.
4277 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
4279 * print.c: New procedure: scm_print_options
4281 * print.h: Defines for print options.
4283 * read.c: New procedure: scm_read_options
4285 * read.h: Defines for reader options.
4287 * root.h: Added scm_source_whash among scm_sys_protects.
4289 * srcprop.c: New file: source properties.
4291 * srcprop.h: New file: source properties.
4293 * throw.c (jbsmob): Jump buffers are now correctly allocated.
4294 (Bug found by A. Green.)
4296 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
4298 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
4300 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
4302 * libguile.h: #include "objprop.h"; I guess this was forgotten.
4304 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
4305 and should be called by the final client.
4307 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
4309 * gc.h: Use the PROTO macro when declaring functions.
4310 * gc.c: Use the PROTO macro when declaring static functions.
4311 Remove the CPP hair around function definitions.
4313 * gc.c (scm_init_storage): Initialize scm_asyncs.
4315 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
4316 preprocessor symbol; "__scm.h" is where it might get #defined.
4317 * __scm.h: Similar: #include <scmconfig.h> before testing
4320 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
4322 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
4324 * init.c (scm_boot_guile): Add init_func argument; call
4325 (*init_func) instead of calling scm_appinit; it's ucky to
4326 hard-code names for the user's procedures.
4327 * init.h (scm_boot_guile): Adjust declaration.
4329 * __scm.h (PROTO): New macro, for declaring functions with
4332 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
4333 eliminate all the __STDC__ conditionals.
4334 (scm_boot_guile): Add declaration.
4335 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
4336 Remove __STDC__ conditionals around function definitions; the
4337 declarations in init.h will provide the same information, more
4340 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
4341 complain about it in the error message; the error message is
4342 adequate without that note, and there's nothing the user can do
4345 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
4347 * Makefile.in (ancillary): Drop def.sed.
4349 * posix.c (scm_init_posix): Use numeric values, rather than
4350 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
4351 F_OK. The symbols aren't available on some systems, and I'm
4352 pretty sure their values are fixed by common widespread practice.
4353 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
4355 More functions unavailable on some systems.
4356 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
4357 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
4359 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
4360 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
4361 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
4362 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
4363 stub that signals an error as the #else.
4365 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
4367 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
4369 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
4371 * unif.c: include ramap.h.
4373 * read.c (endif): case_insensative_p renamed case_insensitive_p.
4375 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
4377 * ports.c: include sys/ioctl.h.
4379 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
4381 * configure.in: check for sys/ioctl.h.
4383 * ports.c: include <malloc.h> not "malloc.h".
4385 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
4387 * fports.c: remove ttyname and tmpnam declarations.
4389 * posix.c: fewer ttyname declarations.
4391 * fports.c: include <string.h> not "string.h".
4393 * init.c, ioext.c: include string.h and unistd.h.
4395 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
4397 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
4398 genio.c, simpos.c, vports.c: include string.h.
4400 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
4402 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
4404 (scm_addr_buffer_size): change type from scm_sizet to int.
4405 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
4406 from scm_sizet to int.
4408 * error.c: include unistd.h.
4410 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
4413 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
4415 * __scm.hd, def.sed: deleted.
4417 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
4419 Changes for NeXT, suggested by Robert Brown.
4420 * configure.in: Call AC_TYPE_MODE_T.
4421 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
4422 NeXT. Put header file list in alphabetical order.
4423 * configure, scmconfig.h.in: Regenerated.
4424 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
4426 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
4429 * acconfig.h: New file, providing documentation for the CPP
4430 symbols defined in configure.in
4431 * acconfig-1.5.h: Removed; superceded by the above.
4433 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
4435 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
4437 * fports.c (scm_open_file): don't return #f, throw error.
4439 * ioext.c (fileno): renamed from %fileno.
4440 (soft-fileno): deleted.
4442 * ports.c (scm_port_revealed): don't need to check for -1 from
4444 (scm_set_port_revealed_x): return unspecified, not #f.
4446 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
4448 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
4450 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
4452 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
4454 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4456 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
4457 This is necessary on Ultrix, and doesn't hurt portability.
4459 * Makefile.in (dist-dir): New target, implementing a new dist system.
4460 (installed_h_files): Put in alphabetical order.
4461 Remove duplicate entries for markers.h and unif.h.
4462 (c_files): Remove duplicate entries for markers.c.
4463 (ancillary): Renamed from anillery; all uses changed. Remove
4464 PLUGIN; it's a directory, and needs special treatment in dist-dir.
4465 Remove all the ../doc/* files; doc/Makefile.in handles that.
4467 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
4469 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
4470 every if must have an else, or else the whole command has a
4471 non-zero exit code whenever the if's condition is false.
4473 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
4475 * posix.c: include string.h.
4477 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4479 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
4482 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
4483 Remove leading % from scheme names.
4484 Do not return error values, call SCM_SYSERROR or similar.
4486 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
4488 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
4490 * struct.c (scm_init_struct): new file.
4492 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
4494 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
4495 (scm_list_head): added list-head for rapidly chopping argument
4496 lists off of longer lists (and similar).

4500 * objprop.c (scm_object_property): assq the cdr of the whash
4501 handle for obj, not the handle itself.
4503 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
4505 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
4506 weak hash tables last of all marking to avoid an obscure gc bug.
4507 WARNING: circular lists stored in a weak hash table will hose us.
4509 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
4511 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
4512 new functions similar to scm_substring_move_left_x and
4513 scm_substring_move_right_x.
4515 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
4517 * init.c (scm_boot_guile): prevent gc with scm_block_gc not

4522 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
4524 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
4526 * strports.c (scm_strprint_obj): convenience function. C for
4527 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
4529 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
4530 removed to a separate library
4532 * init.c (scm_boot_guile): copied from guile-tcl.c.
4533 Initialization specific to tcl interpreters removed.
4535 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
4537 * ports.c (scm_ports_prehistory): size malloced here doesn't
4538 matter so long as it is non-0 (got rid of "* 4").
4540 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
4542 * gscm.h: gscm_mkarray eliminated (presumably was not being used
4543 since its definition was bogus).
4545 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
4547 * mallocs.[ch]: back again (for rx at least).
4549 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
4551 * ports.c: removed functions relating to the mapping between ports
4552 and descriptors. (That stuff is unix-specific and should be collected
4553 in a separate library).
4555 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
4556 (Tom Mckay@avanticorp.com)
4558 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
4560 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
4561 handled correctly (SCM_FREEP was applied to them) -- test for
4562 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
4563 being overwritten with #f. (brown@grettir.bibliotech.com)
4565 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
4567 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs

4570 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
4572 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak

4577 * list.c (scm_last_pair): map '()=>'()
4579 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>

4582 Generalized assoc and hash-table functions.
4583 Factored pairs.c into multiple files.
4585 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
4587 * gscm.c (gscm_run_scm): got rid of objprop.
4589 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
4591 * genio.c (scm_getc):
4592 NOTE: fgetc may not be interruptable.
4594 * procprop.c (scm_stand_in_scm_proc):
4595 NOTE: don't use a alist here.
4596 (scm_set_procedure_properties_x): fix type checking throughout this file.
4598 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
4600 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
4601 after freeing part of the port table.

4605 * strports.c (scm_mkstrport):
4606 * vports.c (scm_make_soft_port): allocate a port table entry
4607 (possibly triggering gc) before setting the tag of the corresponding
4610 * pairs.c (scm_delq_x): never throw an error.
4612 * vectors.c (scm_make_vector): made the default vector fill argument
4613 into '() (much more useful than the previous value, "#unspecified")
4615 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
4617 * ports.c (scm_add_to_port_table): Added fields
4618 to port table entries: file_name, line_num, col.
4619 Update these in open_file, gen_getc and gen_ungetc.
4620 Added procedures to access those fields.
4622 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
4624 * procs.c (scm_make_subr_opt): new entry point for making
4627 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
4629 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
4631 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
4633 * numbers.c (scm_exact_p): This function no longer
4634 implements "integer?".

4638 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
4639 (scm_gc_stats): return an assoc of useful data. Replaces "room"
4640 and the stats reporting formerlly built into repl.
4642 * repl.[ch]: removed.
4643 GC statistics keeping moved to gc.c.
4644 Other statistics keeping can be done from Scheme.
4645 REPLS are now written in Scheme.

4652 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
4654 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
4656 * feature.c (scm_compiled_library_path): moved here from repl.c.
4657 This file is for stuff relating specifically to Scheme libraries
4660 * eval.c (scm_m_define): don't give warning about redefinition, don't
4663 NOTE: this should throw a resumable exception with parameters --
4664 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
4666 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
4668 * error.c: scm_warn eliminated.

4680 between the call to procedurep and use.
4682 * error.c (scm_everr):
4684 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
4687 * strports.c: don't reveal the port's string to the caller
4688 because it changes size.
4690 (stputc stwrite): check/change the strings length with interrupts
4693 * objprop.c (scm_set_object_property_x &c): use the generic
4694 hashing functions and be threadsafe.
4696 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
4697 (per suggestion jaffer@gnu.ai.mit.edu).
4699 * mbstrings.c (scm_multi_byte_string): guard against argument list
4702 * strings.c (scm_make_string): loop cleanup
4704 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer
4707 * weaks.c (scm_weak_vector): guard against argument list
4710 * variable.c (scm_builtin_variable): check for/make a built-in
4713 * vectors.c (scm_vector): while filling the new array,
4714 guard against a list of fill elements that grows after
4715 the vector is allocated.
4717 * hashtab.c -- new file: general hash table
4718 functions. hash, hashq, hashv, hashx.
4720 * tags.h: made wvect an option bit of vector.
4722 Mon Feb 19 09:38:05 1996 Tom Lord <lord@beehive>
4724 * symbols.c: made the basic symbol table operations atomic.
4726 * root.c &c.: collected stack-specific global state.
4727 linum/colnum etc *should* be port-specific state.
4729 * struct.c (scm_init_struct): init the first struct type during
4730 initialization to fix a race condition.
4732 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
4733 object, not in a global.
4734 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
4736 * throw.c (_scm_throw): Pass throwval on the stack, not in a global
4737 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
4739 * *.[ch]: namespace cleanup. Changed all (nearly) exported CPP
4740 and C symbols to begin with SCM_ or scm_.

4744 * gsubr.c (scm_gsubr_apply): statically allocate the
4745 array of arguments (bothner@cygnus.com).
4747 Sat Feb 17 20:20:40 1996 Tom Lord <lord@beehive>

4751 * async.c: New support for interrupt handlers.
4753 Thu Feb 15 11:39:09 1996 Tom Lord <lord@beehive>
4755 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
4756 set the multi_byte flag correctly in symbols. This is wrong.
4757 intern_obbary_soft and msymbolize should take an extra parameter.
4758 Also, weird multibyte symbols don't print correctly.
4759 The weird symbol syntax is also a bit bogus (emacs doesn't quite
4762 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
4764 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
4765 use the system symhash. == #t means create an uninterned symbol.
4767 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
4769 * strings.c (scm_make_shared_substring): build'em.
4770 It might better to keep a table of these and use one
4771 less cons-pair per shared-substring.
4773 Tue Feb 6 17:45:21 1996 Tom Lord <lord@beehive>
4775 * strings.c (scm_string_shared_substring): create shared
