29 errno macro expansion of this field name. (errno is a C
30 preprocessor macro on some systems.)
32 1997-11-29 Tim Pierce <twp@skepsis.com>
36 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>

85 replacement in iselect.c.
86 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
87 coop_join): If GUILE_ISELECT enabled, use
88 coop_wait_for_runnable_thread instead of
89 coop_next_runnable_thread.
90 (usleep, sleep): New replacements for system functions if
91 GUILE_ISELECT is enabled.
93 * coop-threads.h: Declare coop_wait_for_runnable_thread.
95 * coop-defs.h (coop_t): Added fields used by scm_internal_select.

111 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
112 and scm_must_free, since ultimately the string returned will be copied
113 by scm_makfrom0str anyway. Also, read any characters that may have
114 been pushed onto the port with scm_ungetc.
115 * ports.c (scm_generic_fgets): Same as for scm_fgets.
116 * ioext.c (scm_read_line): Free string after Guilifying it.

130 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
132 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
133 and to invoke scm_shell().
134 (gh_launch_pad): took out the loading of boot-9.scm from here,
135 since it is probably best to let the user control that. In fact,
136 gh_repl() now invokes scm_shell() which does that.
138 1997-11-23 Mark Galassi <rosalia@cygnus.com>
140 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

165 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
167 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
168 configure.in was changed).

189 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
190 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):

204 exactly what we want to leave in to detect substrings.
205 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
206 * tags.h: Fix diagrams and comments describing the S tag bit;
207 remove vestigial remarks about the D tag bit.

209 * strings.c: Formatting tweaks.
211 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment

213 (scm_parse_path): New function.
214 * script.c: Doc fixes.
216 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>

245 (gh_assoc): added these gh_ functions implemented as macros.
247 * gh_predicates.c (gh_null_p):
248 (gh_string_equal_p): added these two missing predicates.
250 * gh_list.c (gh_append):

261 * tags.h (scm_tc7_substring): Changed the comment and code to
262 conform with the changes below. Folks! We have suddenly two new
263 free tc7 codes!!! Jummy, jummy!
265 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>

327 * gh_test_c.c (c_vector_test): some improvements on the vector
330 * gh.h (gh_vector): this used to exist but do the wrong thing.
331 Now it (almost) does the right thing, though it takes a list
332 instead of the individual arguments. I need to see how it could
334 (gh_list_to_vector): added this function as a macro. Corresponds
335 to Scheme's (list->vector ...).
336 (gh_vector_to_list): added this function as a macro. Corresponds
337 to Scheme's (vector->list ...).
339 * gh_data.c (gh_vector_ref): renamed from gh_vref to

342 resembles the Scheme routines more.
343 (gh_make_vector): this used to be (stupidly) called gh_vector().
344 This is the right name, since it does the same thing as the Scheme
345 (make-vector ...) procedure.

349 * ports.h: #include "libguile/print.h"

364 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
366 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
367 macros should by convention not test for NIMPness.)
368 (SCM_COERCE_OPORT): Adjust indentation.
370 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
371 SCM_NIMP test before SCM_PRINT_STATE_P.

380 * struct.c (scm_print_struct): Use new printer slot; Default
381 printing: Also output hex code of vtable so that type identity
382 will be indicated as well.
383 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
384 Removed struct_printer_var; Removed struct-vtable-offset;
385 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
386 vtable-offset-user): New constants.

394 transformers. (They are always: exp env.); Bugfix: Unmemoize
395 transformer source with correct environment.
397 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
399 Streamlining of call-with-dynamic-root:
401 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,

403 (cwdr_outer_body): Removed.
404 (cwdr_handler): New function.
405 (scm_internal_cwdr): New function to perform the function of cwdr
406 but take args that are more useful to C code. Also, the handler
407 is now invoked *outside* of the new dynamic root, like the docs
408 say. We no longer have to catch absolutely all errors, the caller
409 is responsible for using a handler that does not throw, if he
411 (cwdr): Reimplemented in terms of scm_internal_cwdr.
412 * root.h (scm_internal_cwdr): New prototype.
414 Even more but risky streamlining:
416 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
417 allocation of the jumpbuf of a root continuation. The changes
418 below are controlled by it. They are now deactivated.
419 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
420 the JMPBUF of the scm_rootcont to NULL before returning.
422 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
423 when they are non-NULL.
424 (scm_gc_mark): Likewise, mark only when non-NULL.
426 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
427 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
429 * gc.c (scm_done_malloc): New function.
430 gc.h (scm_done_malloc): New prototype.
432 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
433 (struct scm_print_state) [revealed]: New field.

440 (scm_print_state_vtable): New variable.
441 (scm_free_print_state): Set `revealed' field to false.
442 (scm_iprin1): Call user supplied closure printer with
443 scm_printer_apply. Print in the traditional way when there isn't

445 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
446 Accept a port/print-state pair in addition to just a port.
447 (scm_prin1): Don't return the print_state to the pool when it has
449 (scm_printer_apply): Set `revealed' field of print_state to true.
450 (scm_init_print): Set scm_print_state_vtable.
451 (print_state_fluid, print_state_fluid_num): Removed.
453 * throw.h (scm_handle_by_proc_catching_all): New prototype

458 * Makefile.in: Regenerated with automake 1.2c.
460 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
462 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
463 was looping endlessly.
465 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
467 * strports.c (scm_eval_string): Don't close the port.
469 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
470 former returns a nice normal integer. (Thanks to Daniel
473 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
475 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
476 makefile variable as a build parameter called LIBS. The
477 build-guile program will use this, for the time being.
478 * Makefile.in: Regenerated.
480 Thanks to Shiro Kawai:
481 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
482 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
485 * Makefile.in: Regenerated with automake 1.2a.
487 * script.c (scm_compile_shell_switches): If we hit the -c or --
488 arguments, don't set the car of (command-line) to scm_usage_name,
489 the prettified name of the guile executable; give it the full
490 path, the way shells usually handle $0.
492 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
494 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
495 Scheme-level name `array-map' and renamed `serial-array-map' to
498 * backtrace.c: Introduced exception handlers which now enclose
499 `display-error' and `display-backtrace' so that error reporting
500 won't get into infinite loops if an error occurs during displaying
501 of the error. This can very easily happen with user supplied
502 print call-back routines.
504 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
506 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
507 the names `serial-array-map' and `array-map' should be removed.)
509 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
511 * init.c (scm_boot_guile_1): Added scm_init_objects ().
512 Added #include "objects.h"
514 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
515 Add #include "feature.h".
517 * Makefile.am (libguile_la_SOURCES): Added objects.c.
518 (modinclude_HEADERS): Added objects.h.
520 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
521 This test is needed at many places in the code and should be
522 abstracted. (Motivated by the need of this test in libguiletk.)
524 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
525 (scm_eval_string), load.c (scm_primitive_load,
526 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
527 Use SCM_EOF_OBJECT_P.
529 * eval.c (scm_init_eval): Add feature `delay'.
531 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
535 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
537 * list.h (SCM_LISTn): New macros. Make list creation in C code
538 prettier. The idea comes from STk.
540 * sequences.h, sequences.c, append.h, append.c: Removed. These
541 files implemented non-R4RS operations which would encourage
542 non-portable programming style and less easy-to-read code.
544 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
547 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
548 sequences.h, #include append.h.
550 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
553 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
555 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
557 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
559 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
561 * eval.c: Added #include "objects.h"
563 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
566 * smob.c (scm_smob_prehistory): Create two objectsmobs with
567 adjacent smob numbers.
569 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
571 * procprop.h: Added declaration of scm_i_inner_name.
573 * gsubr.c: New global symbol scm_i_inner_name.
575 * debug.c (scm_procedure_name): Try procedure property
576 `inner-name' if `name' fails.
578 * print.c (scm_iprin1): Use scm_macro_name.
580 * eval.c (scm_m_define): Give names to macros as well; Only the
581 first top-level definition gives a procedure/macro a name.
582 Otherwise confusing names can turn up in backtraces.
583 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
584 `name'; Give names to macros as well.
586 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
587 (scm_macro_transformer): Use SCM_CLOSUREP instead of
590 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
592 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
594 (prinmacro): Removed. The code has been moved/merged into print.c
595 in order to decrease code redundancy. We want macros to print in
596 a way equivalent to procedures, and it would be silly to duplicate
597 the required code. (We don't want to maintain two places.)
598 (macrosmob): Print field is now a NULL pointer.
600 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
601 scm_macro_transformer): New prototypes.
602 (scm_tc16_macro): Declared.
604 * * print.c (scm_iprin1): Added code for printing of macros. Macros
605 are now printed in a way equivalent to procedures.
607 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
609 * procs.h (scm_closure_p): Added declaration.
611 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
613 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
614 Shouldn't pass "heap" as the subr name.
616 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
618 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
619 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
620 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
621 gh_equal_p): Use SCM_NFALSEP, instead of testing against
622 SCM_BOOL_T. Any non-false value is true.
624 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
626 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
627 scm_gensym): Added prototypes.
629 * symbols.c (scm_gensym): New function. This will speed up
630 certain types of applications (such as macro systems) which
631 generate lots of symbols.
633 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
635 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
637 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
639 * unif.c (scm_shap2ra): tighten the checking of the array dimension
640 specifier, since (2) or (2 . 3) would cause SEGV.
641 (scm_transpose_array): more argument checking fixes.
643 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
645 * Makefile.in: Regenerated.
647 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
649 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
651 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
653 * error.c, error.h (scm_error_callback): Removed (see NEWS).
655 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
657 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
658 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
661 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
662 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
663 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
664 scm_array_p, scm_array_rank, scm_array_dimensions,
665 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
666 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
667 scm_array_prototype): Added case scm_tc7_wvect.
669 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
671 * errno.h: prototype for scm_strerror.
672 * error.c (scm_strerror): new procedure.
674 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
676 * list.c (scm_list_append_x): Allow non-pair as last argument.
677 This is consistent with the R4RS append and is probably the
678 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
680 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
682 * stime.h: prototype for scm_times.
683 * stime.c (scm_times): new procedure.
684 * ioext.c (scm_fseek): if the first argument is a file descriptor

688 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
689 * filesys.c (scm_chmod): if the first argument is a file descriptor,
691 (scm_chown): if the first argument is a port or file descriptor,
693 (scm_truncate_file): new procedure.
694 Add DEFER/ALLOW INTS to a few other procedures.
695 (scm_fsync): new procedure.
696 (scm_open_fdes): new procedure.
697 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
699 (scm_fcntl): the first argument can now be a file descriptor. The
700 third argument is now optional.
702 * posix.c (scm_execl, scm_execlp): make the filename argument
703 compulsory, since omitting it causes SEGV.
704 (scm_sync): return unspecified instead of #f.
705 (scm_execle): new procedure.
706 (environ_list_to_c): new procedure.
707 (scm_environ): use environ_list_to_c. disable interrupts.
708 (scm_convert_exec_args): take pos and subr arguments and
709 improve error checking.
711 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
713 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
714 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
715 argument to SCM_ASSERT. Furthermore, the name of the function
716 should be passed as first argument when signalling
717 SCM_WNA. (Thanks to Thomas Morgan)
719 * gsubr.c (scm_gsubr_apply): From Radey Shouman
720 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
721 dispatches on the number of actual args has a default case
722 reporting an internal error. This is a vestige from a version
723 that mallocated a SCM vector to hold the arguments. In the
724 current version this check is too late: if it ever happens we will
725 have already overstepped the bounds of the array.
727 Also, the patch [...] adds a check for too many actual arguments."
729 mdj: Removed check for "internal programming error".
731 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
733 * gh_io.c (gh_write): New function.
735 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
736 throw.c (scm_internal_stack_catch): New sibling to the other catch
737 functions. Code moved from gh_eval.c.
738 throw.h: Added header.
739 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
740 scm_internal_stack_catch.
742 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
744 * ioext.h: fix up prototypes.
745 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
746 Scheme name is now dup->fdes.
747 (scm_dup_to_fdes): make the second argument optional and
748 fold in the functionality of scm_primitive_dup.
749 (scm_primitive_dup): deleted.
751 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
753 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
754 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
755 ultrix are defined. Use setvbuf instead of setbuf.
756 (scm_setvbuf): new procedure.
757 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
758 (scm_setfileno): moved from ioext.c.
759 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
760 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
762 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>

770 state as nested data while they are printed.
771 (print_state_fluid, print_state_fluid_num): New variables.
772 (scm_init_print): Initialize them.
773 (scm_iprin): If print_state_fluid carries a print_state, use that
774 instead of creating a new one.
775 (scm_printer_apply, apply_stub, struct apply_data): New
776 definitions to help with calling printer functions written in
778 * print.h (scm_printer_apply): New prototype.
780 * struct.c (scm_print_struct): Use scm_printer_apply to call the
781 user defined struct printer.

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

815 * ioext.h: removed scm_duplicate_port prototype.
817 * ioext.c (scm_primitive_dup2): return the new file descriptor
818 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
820 (scm_fdopen): bug fix: don't try to make port unbuffered until its
822 (scm_duplicate_port): deleted, there's now an implementation in
824 (scm_primitive_dup2): do nothing if newfd == oldfd.
826 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>

834 * fluids.c (next_fluid_num): don't do
835 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
837 * ports.h: prototypes too.
838 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
840 * fports.h: prototype too.
841 * fports.c (scm_evict_ports): moved from ioext.c.
843 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
845 * ports.c (scm_close_port): return a boolean instead of unspecified.
846 throw an error if an error other than EBADF occurs.
848 * filesys.h: scm_close prototype.
849 * filesys.c (scm_close): new procedure, can close file descriptors
850 and ports (scsh compatible).
852 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
855 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>

875 data. (dynl_smob): Use it.
876 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
877 the dynamic object data below the linking of the object to avoid
878 memory leak when the linking code throws an error. Now the code
879 leaks a whole dynamically linked library when must_malloc throws,
880 but that should be much less likely.
882 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
884 Changes to compile under gnu-win32, from Marcus Daniels:

891 (scm_addr_vector): Likewise.
892 (scm_init_addr_buffer): Likewise.

896 * scmsigs.c (scm_pause): Don't include unless pause was found
898 * posix.c (scm_getgroups): Don't include unless support function
899 was found during autoconf (in this case, getgroups).
900 (scm_setpwent): For setpwent.
901 (scm_setegid): For setegid.
902 * net_db.c (scm_inet_netof): Don't include unless support
903 function was found during autoconf (in this case, inet_netof).
904 (scm_lnaof): For inet_lnaof.

918 scm_misc_error, not SCM_EOF.
920 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
921 arguments for formatting the error message, not SCM_BOOL_F. I
922 think this is left over from the (eq? '() #f) days.
924 * read.c (recsexpr): Give this a dummy definition if
925 DEBUG_EXTENSIONS isn't #defined.
927 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
929 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

937 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
939 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
940 alloca.lo will be included in @LIBLOBJS@. Something better than
941 this should be possible.

944 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
946 * simpos.h: prototype for scm_primitive_exit.
947 * simpos.c (scm_primitive_exit): new procedure, terminates the
948 process without unwinding the stack.
950 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
952 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
953 argument and logior its components together, so the user doesn't
954 have to do this explicitly. Also, if regexp/basic is supplied, then
955 turn off REG_EXTENDED.
956 (scm_init_regex_posix): New regexp/basic symbol.
957 (REG_BASIC): #define this if it is not already present.
959 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
961 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.

970 years in usage message.
972 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
973 * Makefile.in: Regenerated.
975 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
976 flag; I don't think we support it.
977 (scm_make_regexp): Make sure the user doesn't pass the
980 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
982 (scm_init_regex_posix): Define constants for the REG_mumble flags;
983 name them according to the SCSH convention: regexp/mumble.
985 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
987 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
989 * Makefile.am (libpath.h): Include the values of all the standard
990 Makefile directory variables. Print a message, but don't print

994 (init_build_info): New function.
995 (scm_init_load): Call it.
996 * Makefile.in: Regenerated.
998 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
1000 * root.c: Establish a reliable catch-all handler for the new root.
1001 After all the Scheme handler function might signal an error too,
1002 and we don't want to lose that.
1003 (cwdr_inner_body): Renamed from cwdr_body.
1004 (cwdr_outer_body): New function, to establish the user's handler,
1005 and pass control to cwdr_inner_body.
1006 (cwdr): Establish the reliable catch-all handler here, and pass
1007 control to cwdr_outer_body.
1008 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
1009 the user's handler through to cwdr_outer_body.
1010 * throw.c (scm_handle_by_message): Move guts into....
1011 (handler_message): New static function.
1012 (scm_handle_by_message_noexit): New function.
1013 * throw.h (scm_handle_by_message_noexit): New prototype.
1015 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
1016 across this. Only works on GCC. Otherwise, we hope for the best.
1017 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
1018 the feeling that real thread systems will not need this...
1020 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
1022 Try to detect when people are using one version of libguile and a
1023 different version of ice-9. People have been skewing things and
1024 sending in bug reports.
1025 * Makefile.am (versiondat.h): New file to generate.
1026 * version.c: #include "versiondat.h", to get version info.
1027 (scm_libguile_config_stamp): New function.
1028 * script.c: #include "version.h".
1029 (scm_compile_switches): Call scm_version to get version number.
1030 * scmconfig.h.in, Makefile.in: Regenerated.
1031 * Makefile.in: Regenerated.
1033 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
1034 primitive definitions under their Scheme names.
1036 * Makefile.am (libguile_la_LDFLAGS): Update library version to
1037 1:2. Helps avoid confusion between installed and uninstalled libs.
1039 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
1042 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
1043 backslash from definition; this should be used like: GDB_INTERFACE;
1045 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1047 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
1048 new port unbuffered until its stream has been set.
1050 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
1052 * ports.h: new prototype.
1053 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
1055 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
1057 Make things compile neatly under Sun's C compiler.
1058 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
1059 * extchrs.c (xmbtowc): Make the second arg a normal char, not
1060 unsigned, because that's what the ANSI function takes.
1061 * extchrs.h (xmbtowc): Corresponding change to prototype.
1062 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
1064 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
1065 argument plain char *.
1066 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
1068 * tag.c (scm_tag): Remove unreachable statement.
1069 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
1070 top of the word, it should be unsigned.
1072 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
1073 is defined, to avoid warnings; it's only used in the
1074 conflict-checking code. Which might go away anyway.
1075 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
1076 conditionals; put the label definition in an #if too, to stifle
1079 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
1080 ChangeLog-threads in the distribution.
1081 * Makefile.in: Regenerated.
1083 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1085 * guile-snarf.in: Changed regexp to support CPPs that insert
1086 whitespace between lexical tokens (which munges the `%%%' snarf
1089 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1091 * load.c (scm_init_load_path): Append $(datadir)/guile to
1092 %load-path, so modules do not have to be installed in Guile's
1093 current version directory.
1095 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
1097 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
1098 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
1099 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
1100 call the sysdep functions with deferred ints.
1101 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
1102 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
1103 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
1106 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
1109 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
1111 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
1113 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
1115 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
1118 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
1120 * eval.c (scm_lookupcar1): New procedure to cope with a race
1121 condition during lookup (when using threads).
1122 (scm_lookupcar): Implement in terms of scm_lookupcar1.
1123 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
1126 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
1128 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
1129 supplied. (Change from Tim Pierce.)
1131 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
1133 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
1134 23:47:01 1997" changelog: Slots are now initialized with `#f' by
1135 default and not `()'. `#f' is the canonical non-value in Scheme,
1138 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1140 * struct.c (struct_printer): New variable that holds a handle on
1141 the Scheme variable *struct-printer*. This variable can be set by
1142 Scheme code to override the printing of structures.
1143 (scm_print_struct): If struct_printer is set, call it. If it is
1144 not set, or returns #f, print the structure in the old fashion.
1145 Include "eval.h" for scm_apply.
1147 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
1149 * struct.c (scm_struct_ref, scm_struct_set_x): Use
1150 scm_struct_i_n_words to get the number of fields, not
1151 -scm_struct_n_extra_words.
1153 On the route to fancier struct printing:
1154 * struct.c (scm_print_struct): New function to print a structure.
1155 Include "genio.h" to support it. This function doesn't do
1156 anything interesting right now, but I think it should be here
1158 * struct.h: Include "print.h" and add prototype for
1160 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
1161 print structures ourself.
1163 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
1165 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
1166 before applying the handler in case it doesn't return.
1168 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
1170 * scmsigs.h, async.h: updated.
1172 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
1175 * posix.c (scm_uname): interpret only negative values as an error.
1176 Solaris normally returns a positive value.
1178 * script.c (scm_compile_shell_switches): if we are not going into
1179 an interactive repl, set scm_mask_ints to zero so that asyncs can
1182 * simpos.c (scm_system): don't ignore/unignore signals around
1185 * posix.c (scm_open_pipe): don't ignore/unignore signals around
1188 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
1189 done in boot-9.scm instead.
1191 * scmsigs.c, async.c: Major rewriting of signal handling code.
1192 (scm_sigaction): new procedure.
1193 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
1195 (scm_raise): return unspecified, throw error on failure.
1197 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
1199 * regex-posix.c (scm_init_regex_posix): Register the "regex"
1200 feature, to help boot-9.scm decide whether to import the regex
1203 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
1205 * eval.c: Include scmconfig.h at the beginning of the file so that
1206 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
1209 * regex-posix.c: #include "_scm.h" before conditionally #including
1210 <regex.h>; the former defines HAVE_REGCOMP.
1212 * regex-posix.c: #include <regex.h> conditionally, so the file is
1213 CPP'able (for dependency scanning) even on systems that don't have
1216 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
1218 Add new R4RS-compliant syntax for keywords.
1219 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
1220 regardless of the setting of the `keywords' read option.
1221 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
1222 can be re-read no matter what the setting of the `keywords' read
1225 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
1227 Add support for POSIX regular expressions.
1229 * regex-posix.c, regex-posix.h: New files. (Some code
1230 is taken liberally from rx/rgx.c in the old Guile dist.)
1232 * init.c: Include regex-posix.h.
1233 (scm_boot_guile_1): Call scm_init_regex_posix.
1235 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
1236 Add regex-posix.[ch] sources.
1237 * Makefile.in: Regenerated.
1239 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
1240 to do this automatically? It didn't for me, bleh.)
1242 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
1244 * fports.c (print_pipe_port): New function.
1245 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
1246 latter doesn't even take the right arguments.
1248 * Makefile.am: Increment shared lib revision number. I think
1249 sometimes the uninstalled Guile finds the installed shared lib;
1250 Gord says doing this might help. As things turned out, I can't
1251 say whether it does.
1252 * Makefile.in: Regenerated.
1254 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
1255 passing it as the closure argument to scm_boot_guile. (Bill
1258 * ports.c (print_void_port, putc_void_port, puts_void_port,
1259 write_void_port, flush_void_port, getc_void_port, close_void_port,
1260 noop0): Use ANSI prototypes instead of K&R declarations, so the
1261 initialization of void_port_ptob gets aggressively type-checked.
1262 Fix arguments of print_void_port and write_void_port. (Bill

1296 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
1298 * script.c (scm_find_executable): Use prototype-style definition
1299 here; apparently it's not quite right to have const in a prototype
1300 and then use a K&R declaration. I wonder if stuff like this will
1301 go away if we compile with -Wrequire-prototypes, or whatever that
1302 is... (Bernard URBAN)
1304 * scmhob.h: New text from Bernard URBAN.
1306 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
1308 * script.c: Don't #define const on hpux. Configure takes care of
1309 this. (Thanks to Larry Schwimmer.)
1311 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
1312 decide whether to #include <unistd.h>, instead of listing a bunch
1313 of systems. Don't #include stdio twice. Removed dyked-out
1314 definition of scm_find_impl_file.
1316 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
1318 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
1319 library version info to 1:0.

1326 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
1327 throw.c: Update copyright years; these files have been worked on
1328 significantly in 1997, but only had copyright years for 1996.
1329 Also, change name of copyright holder on some from Mikael
1330 Djurfeldt to Free Software Foundation; he has signed papers
1331 assigning the changes to the FSF.
1333 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
1334 reason not to give the user the option.
1336 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
1337 Return #f on end-of-file when scanning table (i.e. when called
1338 with no arguments). Try to catch errors, when we can.
1339 * posix.c (scm_getgrgid, scm_getpwuid): Same.
1341 * script.h (scm_shell_usage, scm_compile_shell_switches): New
1342 external declarations. These are useful.
1344 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
1346 * posix.c: don't include <sys/select.h> or define macros for
1347 select, since they were not used in this file.
1349 * filesys.c (scm_select): make the fifth parameter microseconds,
1350 not milliseconds. let the fourth parameter be either a real value
1351 or an integer or #f. The first, second and third arguments can
1352 now be vectors: the type of the corresponding return set will be
1354 (set_element, get_element): new static procedures.
1356 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
1358 * strports.c (scm_eval_string): New function.

1361 * strports.h (scm_eval_string): New extern decl.
1363 * net_db.c (h_errno): Add extern decl for this.
1365 * fports.c (local_pclose): New function.
1366 (scm_pipob): Use it in the initializer here.
1369 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
1370 Use a meaningful error message when signalling an error. For
1371 this, scm_gethost must check h_errno rather than errno.
1373 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
1375 * Makefile.in: Regenerated, using automake-1.1p.
1377 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
1379 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
1380 not SCM_UNSPECIFIED.
1382 * script.c (scm_compile_shell_switches): don't append (quit) if
1384 (scm_shell): call scm_exit_status and exit on the result of the
1387 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
1389 Ensure that shared substrings are handled properly when passed to
1390 a system call or other foreign function. Many thanks to Tim
1392 * symbols.h (SCM_COERCE_SUBSTR): new macro.
1393 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
1394 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
1395 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

1407 SCM_COERCE_SUBSTR to make sure shared substrings are
1410 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
1412 * error.c (scm_error): Add newline to error message.
1414 * init.c (scm_init_standard_ports): Doc fix.
1416 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1418 * dynl-shl.c: Completely replaced with new code from Bernard
1421 * script.c (scm_ice_9_already_loaded): New variable.
1422 (scm_compile_shell_switches): Use it.
1424 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1426 * filesys.c (scm_input_waiting_p): add missing third argument to

1430 calling gmtime in case they share a buffer.
1431 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
1434 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1436 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
1438 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
1440 * Makefile.am (check-local): New target, which causes 'make check'
1441 to run gh_test_c and gh_test_repl, with some trivial input.
1442 * Makefile.in: Rgnrtd.
1444 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
1446 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
1449 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
1451 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
1452 sure how this was supposed to work.
1453 (scm_async_click): don't send SCM_TICK_SIGNAL.
1454 (scm_init_async): don't initialize %tick-thunk.
1456 * the following change doesn't affect the Scheme interface:
1457 gc-thunk is called at the end of garbage collection. however it's
1458 no longer implemented by pretending it's a signal.
1460 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
1461 system async corresponding to scm_gc_thunk.
1462 * async.h: declare scm_gc_async.
1463 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
1464 gc-thunk directly, instead of going through a signal handler.
1465 (scm_gc_async): new variable, points to the GC system-async.
1466 (scm_init_async): save the GC async as scm_gc_async instead
1467 of using system_signal_asyncs.
1468 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
1470 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
1472 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
1473 Don't screw up if we're interrupted.
1474 * Makefile.in: Regeneradet.
1476 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
1478 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
1480 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
1481 we're not using AM_INIT_GUILE_MODULE any more.
1482 * Makefile.in: Reneregated.
1484 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
1486 Functions for finding variable bindings, grace à Tim Pierce.
1487 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
1488 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
1490 Get 'make dist' to work again.
1491 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
1492 * Makefile.in: Regenerated, like a surry without a fringe on top.
1494 Changes for reduced Guile distribution: one configure script,
1496 * configure.in, configure: Removed.
1497 * acconfig.h, acinclude.m4: Moved to parent directory, where the
1498 real configure script lives.
1499 * Makefile.in, scmconfig.h.in: Regenerated.
1501 * init.c: #include "script.h", to get prototype for script.c's
1504 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
1506 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
1507 scm_must_malloc, not raw malloc.
1509 * script.c (scm_compile_shell_switches): Dyke out debugging output
1512 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1514 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
1516 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
1517 system has them. Hope this is safe. Previously
1518 sys/timeb.h was included if HAVE_FTIME was defined or if
1519 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
1520 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
1522 * ioext.c (scm_setfileno): add missing third argument to
1523 scm_misc_error call.
1525 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
1527 * eq.c (scm_equal_p): Correctly compare strings of different
1528 varieties. (Thanks to Tim Pierce.)
1530 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
1532 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
1533 #! block comment must occur on a line all by itself.
1535 Move most of the guts of shell command processing into libguile,
1536 so guile.c can be very small (and eventuallly auto-generated. (I
1537 mean, generated mechanically, not self-generated. Hmm.))
1538 * guile.c, script.c, script.h: New source files.
1539 * init.c (scm_boot_guile_1): Call scm_init_script.
1540 * libguile.h: #include "script.h".
1541 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
1542 targets, for new executable.
1543 (libguile_la_SOURCES): Mention script.c.
1544 (modinclude_HEADERS): Add script.h.
1545 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
1546 not dynamic linking is enabled. This is because we're generating
1547 executables now. Move CY_AC_WITH_THREADS call after those, so the
1548 values of cy_cv_threads_libs captures the libs chosen above.
1549 * Makefile.in, configure, aclocal.m4: Regenerated.
1551 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
1552 We don't maintain this interface any more, and it just confuses
1555 * alloca.c: #include <scmconfig.h>, not <config.h>.
1556 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
1557 it'll get included in disties.
1559 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
1561 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
1562 be distributed, because they confuse people.
1563 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
1565 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
1567 * configure.in: check for presence of gethostent (not present on
1568 OpenBSD by default).
1569 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
1570 * configure, scmconfig.h.in: Regenerated.
1572 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
1574 * backtrace.c (scm_backtrace): Split message string across
1575 newlines properly. GCC is more tolerant of this than other
1578 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
1580 Merge threads directory into libguile.
1581 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
1582 threads.h: New source files.
1583 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
1584 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
1586 (modinclude_HEADERS): Add threads.h, coop-defs.h.
1587 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
1588 coop-threads.c.cygnus, coop-threads.h.cygnus.
1589 * configure.in: If we're using threads, include threads.o in
1591 * _scm.h, libguile.h: threads.h lives in this directory now.
1592 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
1593 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
1594 currently used, but brought along for information's sake.
1595 * ChangeLog-threads: log from old 'threads' directory.
1596 * Makefile.in, configure: Rebuilt.
1598 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
1600 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
1603 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
1605 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
1607 Merge GH interface library into libguile.
1608 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
1609 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
1610 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
1611 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
1613 (EXTRA_libguile_la_SOURCES): ... here.
1614 (pkginclude_HEADERS): Add variable, to get gh.h installed.
1615 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
1616 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
1617 New variables, describing how to build the gh test programs.
1618 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
1619 build the test programs, and we probably should have been linking
1620 libguile.la against them all along, to support AIX shared libs.
1621 Add cflags for threads to CFLAGS; add libs for threads to new
1622 variable THREAD_LIBS, used in Makefile.am.
1623 * ChangeLog-gh: log from old `gh' subdirectory.
1624 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
1626 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
1628 * acconfig.h: Undo change of Apr 9; including the definition of
1629 PACKAGE in the guile headers conflicts with applications' own
1631 * scmconfig.h.in: Regenerated.
1633 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

1640 when PROC is receiving no arguments.
1642 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
1644 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
1645 have S_IFSOCK. This is the case under Ultrix.
1647 * posix.c (scm_status_exit_val, scm_status_exit_val,
1648 scm_status_term_sig, scm_status_stop_sig): Modified to work with
1649 Ultrix versions of WIFSTOPPED, etc., which assume that their
1650 arguments are lvalues (hmm).
1652 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
1654 * eval.c: Doc fixes.
1656 * throw.c: Doc fixes; rearranged.
1658 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
1660 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
1662 * acconfig.h: Added entry for PACKAGE.
1663 * scmconfig.h.in: Regenerated.
1665 Changes to work with automake-1.1n, which has better libtool support.
1666 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
1667 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
1669 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
1671 * Makefile.in: Rebuild.
1673 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1675 * stime.c (scm_mktime): take an optional zone argument.
1676 (scm_localtime): check putenv return value.
1677 (scm_strftime, scm_strptime): moved from posix.c. move #include
1679 stime.h, posix.h: update prototypes.
1680 (bdtime2c, setzone, restorezone): new static procedures.
1681 (scm_mktime, scm_strftime): use them.
1682 (scm_strftime): don't call mktime before strftime. Use
1683 filltime for return value.
1684 (filltime): convert NULL zname to #f.
1685 (scm_strptime): return a count of characters consumed, not
1686 the remaining string.
1688 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1690 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
1691 (scm_mktime): likewise.
1693 Uncomment localtime and mktime.
1695 * configure.in: add AC_STRUCT_TIMEZONE.
1697 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
1699 * stime.c (scm_init_stime): don't define ticks/sec.
1700 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
1701 return value problem and is still portable.)
1703 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
1705 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
1706 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
1707 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
1708 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
1709 cpp_err_symbols.c): Corresponding changes.
1710 * Makefile.in: Regenerated.
1712 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
1714 * posix.c (scm_putenv): don't check HAVE_PUTENV.
1715 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
1716 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
1717 * putenv.c: new file, from sh-utils 1.12.
1719 * posix.c (scm_environ): use malloc in place of scm_must_malloc
1720 since allocation isn't for Scheme objects.
1721 (scm_putenv): copy strings before placing in the environment.
1723 * stime.c (scm_current_time): throw an error if time returns -1,
1724 instead of returning #f.
1725 (scm_get_internal_real_time, scm_get_internal_real_time): use
1726 scm_long2num for return value instead of SCM_MAKINUM.
1728 * stime.h: prototypes updated.
1730 * stime.c (scm_time_in_msec): apparently unused, deleted.
1732 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
1734 * configure.in: check for gettimeofday.
1736 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
1737 which may be more usefully portable than a gettimeofday interface.
1739 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
1741 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
1743 * Makefile.in: Regenerated.
1745 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
1747 * stime.c (filltime): recovered static procedure.
1748 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
1751 * posix.h: add prototype for scm_close_pipe, remove prototypes for
1752 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
1754 * posix.c (scm_mknod): split the mode argument into type and perms
1755 arguments, like the extra fields returned by stat.
1757 * fports.c (scm_pipob): set the close, free and print procedures.
1758 (scm_close_pipe): new procedure.
1760 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
1761 define them in boot-9.scm
1763 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1765 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
1766 wan't defined. Don't include fd.h.
1768 * Previously fd.h was regenerated whenever configure was run,
1769 forcing a couple of files to be recompiled.
1771 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
1772 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
1773 Check for _fileno as well as _file.
1775 * ioext.c: don't fd.h.
1776 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
1779 * Change the stratigy for getting information about errno
1780 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
1781 generating lists of symbols during the build process, which will
1782 not always work, include comprehensive lists in the distribution.
1783 To help keep the lists up to date, the "check_signals" and
1784 "check_errnos" make targets can be used.
1786 * configure.in: don't check for a command to extract errno codes.
1787 * Makefile.am: update file lists, remove errnos.list and errnos.c
1788 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
1789 check_errnos targets.
1790 (CLEANFILES): remove errnos.c and errnos.list, add
1791 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
1792 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
1793 * errnos.default: deleted.
1794 * cpp_signal.c: new file.
1795 * cpp_errno.c: renamed from errnos_get.c.
1796 * cpp_err_symbols, cpp_sig_symbols: new files.
1797 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
1798 * error.c (scm_init_error): #include cpp_err_symbols instead of
1800 * posix.c (scm_init_posix): don't intern signal symbols. #include
1803 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
1805 * strop.c (scm_i_index): allow the lower bound to be equal to the
1806 length of the string, so a null string doesn't always give an error.
1808 * posix.h: new prototypes.
1809 * posix.c (scm_status_exit_val, scm_status_term_sig,
1810 scm_status_stop_sig): new functions, as in scsh. They break down
1811 process status values as returned by waitpid.
1813 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
1815 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
1816 configure doesn't know about it.
1818 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1820 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
1822 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
1823 which defines C variables with global linkage.
1825 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1827 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
1830 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
1832 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
1833 has time to check why this doesn't work well with continuations.
1835 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
1837 * Fix shell syntax error; some shells won't tolerate
1838 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
1840 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
1842 * posix.c (scm_uname): throw an error if uname fails instead
1845 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
1847 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
1850 * async.c (scm_ints_disabled): definition moved from error.c.
1852 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1854 * acconfig.h: Removed PACKAGE.
1856 * scmconfig.h.in: Regenerated.
1858 * snarf.h: g++ says it's non-portable not to specify the first
1859 argument in a varargs declaration. I introduced the first
1860 argument by using preprocessor conditionals.
1862 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
1864 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
1865 (scm_freopen): use RO string macros for filename and modes.
1866 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
1868 * posix.c (scm_getgrgid): simplify conversion of name to C string.
1869 (scm_mknod): use RO string macros for path.
1871 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
1872 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
1874 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
1875 use SCM_ROSTRINGP and SCM_ROCHARS.
1877 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1879 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
1882 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
1883 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
1884 support for byte vectors.
1886 * print.c (scm_iprin1): Limit number of vector elements printed
1887 according to pstate->length.
1889 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
1891 * backtrace.c (scm_display_error_message): don't segv if message
1894 * error.h: prototype for scm_error_scm.
1896 * error.c (scm_error_scm): new procedure, reimplements scm-error
1897 in C and uses scm_error.
1899 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
1901 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
1902 pointer to the Scheme variable read-hash-procedures and intern it
1903 in scm_init_read. Modify scm_read_hash_extend and
1904 scm_get_hash_procedure to use the pointer.
1906 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1908 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
1909 (SCM_KEYWORD_STYLE): defined.
1911 * read.c (scm_read_opts): add a keywords option. This isn't a
1912 boolean option, in case someone wants to add support for DSSSL
1914 Setup scm_keyword_prefix symbol.
1915 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
1917 I've left keyword support disabled by default, since it doesn't
1918 seem to break the module system and it gives R4RS standard behaviour.
1919 It can be reactivated with (read-set! keywords 'prefix).
1921 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1923 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
1924 before constructing arbiter.
1926 * eval.c (scm_m_define): Bugfix: Check that the object is a
1927 closure before setting the procedure property!
1929 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
1931 * ports.c: Removed `ungetc-char-ready?'.
1933 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
1935 * read.c (scm_init_read): intitialise scm_read_hash_procedures
1936 (idea from Mikael: make it a pair so scm_permanent object only
1938 (scm_read_hash_extend): don't call scm_permanent_object.
1939 (ideas from Mikael): if chr is already in the list, replace its
1940 procedure instead of appending it again. If proc is #f, remove
1942 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
1944 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
1946 * gdbint.c (gdb_read): update scm_lreadr usage.
1948 * load.h: update prototypes.
1950 * load.c (scm_primitive_load, scm_read_and_eval_x,
1951 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
1953 * read.h: add prototype for scm_read_hash_extend. Change args for
1956 * read.c (scm_read_hash_procedures): new variable.
1957 (scm_read_hash_extend): new procedure.
1958 (scm_get_hash_procedure): new procedure.
1959 (scm_lreadr): use scm_get_hash_procedure instead of an argument
1960 for extended # processing.
1961 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
1962 scm_read_token): remove case_i, sharp arguments. Change callers.
1964 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
1966 * read.h (SCM_N_READ_OPTIONS): increase to 3.
1967 (SCM_CASE_INSENSITIVE_P): define.
1969 * read.c: add case-insensitive option to scm_read_opts.
1970 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
1971 to determine whether to convert symbol case.
1972 (default_case_i): definition removed.
1973 * read.c (scm_read_token): if case_i, downcase ic before doing
1976 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1978 * configure.in: Added configuration option `guile-debug'.
1979 Configure with --enable-guile-debug if you want a bunch of extra
1980 functions used for debugging when developing Guile.
1982 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
1984 * procs.c (make-cclo): New undocumented debugging procedure: Make
1985 compiled closure with internal procedure PROC and length LENGTH.
1986 Only compiled if GUILE_DEBUG is defined.
1988 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
1990 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
1992 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
1994 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
1995 with 3 or more args internally to the evaluator.
1997 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1999 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
2000 with 3 or more args internally to the evaluator. This is mainly
2001 because we don't want to pass entry and exit points of the
2002 debug support twice, but it also seems to increase the speed of
2003 the evaluator for such calls (e. g. (+ 1 2 3)).
2005 * backtrace.c (scm_display_application): New procedure:
2006 display-application; Set fancy printing parameters individually
2007 for different types of display (backtrace, error, application).
2008 (These should of course be customizable!)
2010 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
2011 clear the CHECK-flags.
2013 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2015 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
2017 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2019 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
2020 from pairs with a GLOC in the car.
2022 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
2023 otherwise `symbol-hash' will behave badly.
2024 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
2025 we get segmentation fault!
2027 * symbols.c: Added #include "weaks.h". New functions:
2028 `builtin-bindings' and `builtin-weak-bindings'. (These will be
2029 moved to an extraneous library when we split libguile.)
2031 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2033 * filesys.c (scm_stat): stat now takes fport arguments too as
2034 documented in the manual.
2036 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2038 * debug.c (scm_single_step): Bugfix: Call continuation with
2039 scm_call_continuation instead of throwing to it.
2041 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
2043 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
2044 argument wasn't declared to be optional.
2046 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2048 * stime.c (scm_init_stime): Add feature "current-time".
2050 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2052 * throw.h: prototype for scm_exit_status.
2053 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
2054 args to derive an exit status. Allows (quit) to work from a
2056 (scm_exit_status): new function.
2059 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2061 * eval.c (scm_deval): Removed some old code.
2062 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
2064 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
2067 * symbols.c (msymbolize): Bugfix: Must initialize property list to
2070 * procs.c: Introduce the existent C function scm_thunk_p at the
2071 Scheme level as well.
2073 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2075 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
2076 used from C to easily lookup the value of a symbol in the current
2079 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2081 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
2082 scm_init_unif in this file. This will also fix a previous problem
2085 * configure.in: Added AM_MAINTAINER_MODE
2087 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2089 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
2092 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
2094 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
2095 source files that are not always included in libguile but should
2096 have their dependencies calculated by automake. This variable is
2097 recognized by automake, no further magic is needed.
2098 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
2099 to deal exclusively with *.lo files, as it seems. The *.o files
2100 are built automatically when the corresponding *.lo file gets
2103 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
2105 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
2108 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
2110 * unif.c (scm_array_set_x): minor change to argument error checking.
2112 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
2114 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
2115 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
2116 They should only be included in the library at configure.in's
2118 (libguile_la_LDADD): Include the appropriate .lo files here.
2119 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
2120 so we know when to build them (and their .lo bretheren).
2121 * configure.in (LIBLOBJS): New substituted variable. We let
2122 configure decide which .o files to include in LIBOBJS, and then
2123 put the corresponding list of .lo files in LIBLOBJS. The latter
2124 is what we pass to libtool.
2125 * Makefile.in, configure: regenerated.
2127 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
2129 * symbols.c (scm_sysintern0): New function. Contains the core of
2130 old scm_sysintern but doesn't take a second value argument.
2131 (scm_sysintern): Now uses scm_sysintern0.
2132 (scm_sysintern_no_module_lookup): Renamed to
2133 scm_sysintern0_no_module_lookup and doesn't take a second value
2134 argument any longer.
2136 * symbols.h (scm_sysintern0: Added declaration.
2138 * options.c (scm_init_opts): Use scm_sysintern0 instead of
2139 scm_sysintern when interning option keys. Otherwise we risk
2140 destroying the values of already interned variables.
2142 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
2143 scheme-level boolean (use SCM_NFALSEP).
2145 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
2147 (scm_backtrace): New function. (C version of old function from
2148 boot-9.scm) Motivation: Make it possible to display backtraces
2149 without depending on boot-9.scm. (I'm uncertain if this
2150 motivation is good enough...)
2152 * root.h (scm_root_state): Add member the_last_stack_var.
2153 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
2155 * root.c (mark_root): Mark scm_the_last_stack_var.
2157 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
2160 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
2162 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
2163 1. mark_lazy_catch didn't mark the smob.
2164 2. Both functions above have standard variants:
2165 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
2166 free_lazy_catch --> scm_free0.
2168 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
2170 * throw.c (scm_internal_lazy_catch): New function.
2171 (scm_lazy_catch): Rewritten to use it.
2172 (scm_ithrow): Handle the new lazy catch representation.
2173 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
2174 that doesn't have a jmpbuf is a lazy catch clause.
2175 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
2176 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
2177 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
2179 (scm_init_throw): Register the new lazy-catch smob type.
2180 * throw.h (scm_internal_lazy_catch): decl for new function.
2182 * throw.c (scm_internal_catch): Doc fixes.
2184 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
2185 configure.in. Including this might cause problems if applications
2186 that link against libguile include their own copies of alloca, but
2187 if they're using autoconf, they should be adding libguile to LIBS
2188 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
2189 the copy in libguile, and things will be okay. (I think.)
2191 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2193 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
2195 strop.h: move prototypes too.
2197 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2199 * posix.c (scm_init_posix): don't intern EINTR since it's now done
2202 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
2203 etc. I deleted them from filesys.c long ago, but didn't
2204 notice they were here too (although ineffective since
2205 sys/stat.h wasn't included).
2207 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
2209 * eval.c: Don't define alloca in GCC case. gcc will automatically
2210 use __builtin_alloca if appropriate.
2212 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2214 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
2215 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
2216 that values of automatic variables are preserved. See comments
2217 for safe_setjmp for details.
2219 Change from Thomas Morgan:
2220 * variable.c: Include eq.h.
2221 (var_equal): New function.
2222 (variable_smob): Use var_equal as the discriminator for variables.
2224 * throw.c (s_throw): Remove extraneous declaration.
2226 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
2227 * eval.c: Add necessary CPP cruft to support that.
2228 * configure, Makefile.in, scmconfig.h.in: regenerated.
2230 Change from Thomas Morgan:
2231 * procprop.c (scm_procedure_properties): Convert the Scheme
2232 boolean returned by scm_procedure_p into a C boolean before using
2233 it as a condition for SCM_ASSERT.
2234 (scm_procedure_property): Likewise.
2236 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
2237 indications of Unixness.
2240 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2242 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
2244 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2246 * read.c (scm_lreadr): use scm_misc_error to improve one of the
2247 "unknown # object" error messages.
2249 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
2250 (scm_i_index) and declare it static. Add a 'direction' argument
2251 to indicate what way the search should go.
2252 (scm_i_index): throw out-of-range error instead of wrong-type-arg
2254 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
2255 strop.h: remove scm_i_index, scm_i_rindex prototypes.
2257 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2259 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
2261 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
2262 to avoid clash with various scsh forks.
2264 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
2266 The following two changes (ramap.c, throw.c) are motivated by the
2267 apparent unportability of forward declarations of static arrays of
2268 the form `static foo bar[];'.
2270 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
2271 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
2273 * throw.c (scm_throw): Moved above scm_ithrow.
2275 * options.h: Removed the extern declarations of scm_yes_sym and
2276 scm_no_sym since these are static.
2278 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2280 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
2282 * Makefile.am: remove AWK=@AWK@.
2283 Add a rule for generating errnos.list.
2284 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
2286 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
2287 don't extract errnos, just set a variable (avoids the
2288 need to recompile error.c just because configure is run.)
2290 * unif.h: update prototypes.
2291 * unif.c (scm_uniform_array_read,write): change the offset and
2292 length arguments to start and end, for consistency.
2294 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
2296 * ioext.h: update prototypes.
2297 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
2298 scm_read_line_x, it's a more general procedure using an
2299 interface from scsh. read-line and read-line! are now defined
2301 Note that the new read-line trims the terminator
2302 by default, previously it was appended to the returned string. An
2303 optional argument specifies how to process the terminator (scsh
2304 compatible). For the old behaviour: (read-line port 'concat).
2305 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
2306 returns a pair, but is converted to multiple values if the scsh
2309 socket.h: update prototypes.
2310 * socket.c (scm_recvfrom): for consistency with other procedures,
2311 take start and end as separate optional arguments.
2312 (scm_recv, scm_recvfrom): don't allow the second argument
2313 to be a size, only a buffer. Change the scheme names to
2314 recv! and recvfrom!. Don't return the buffer.
2316 * ioext.h, posix.h: move prototypes too.
2317 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
2318 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
2319 "read.h" and "unif.h".
2320 * ioext.c: include "chars.h"
2322 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
2324 * dynl.c: The dynamic linking and module registration functions
2325 are now defined even when dynamic linking is not available for the
2326 host system. Some of their functionality can be done without
2327 dynamic linking; when it's really needed, they throw errors.
2329 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
2331 * configure.in: Only define DYNAMIC_LINKING when one of the system
2332 dependent functions is detected.
2333 * dynl.c (scm_dynamic_func): New function to get the address of a
2334 function in a dynamic object.
2335 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
2336 produced by scm_dynamic_func as the thing to call.
2338 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
2340 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
2341 (scm_register_module_xxx, scm_registered_modules,
2342 scm_clear_registered_modules): New functions.
2344 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
2346 * symbols.c (scm_sysintern): Renamed to
2347 scm_sysintern_no_module_lookup.
2348 (scm_sysintern): New function to take the place of the old
2349 scm_sysintern. It uses the current toplevel lookup closure to give
2350 the symbol its value. This is a temporary hack to put packages
2351 like gtcltk into their own module.
2352 (scm_can_use_top_level_lookup_closure_var): New variable to tell
2353 us whether `scm_top_level_lookup_closure_var' has been initialized
2355 * eval.c (scm_init_eval): Set it.
2357 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2359 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
2360 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
2362 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
2364 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
2365 scm_sys_dup): deleted: FD capability will be added to other
2367 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
2368 scm_fd_free, fd_smob, scm_intern_fd.
2369 (scm_open): renamed from scm_sys_open. Return a port instead of
2370 an FD object. Make the mode argument optional.
2371 (scm_sys_create): deleted, it's just a special case of open.
2372 (scm_init_filesys): move interning of constants O_CREAT etc.,
2373 here (were previously using SCM_CONST_LONG macro).
2374 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
2376 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
2377 include "fports.h" and <stdio.h>
2378 (scm_stat, scm_select): don't support FD objects.
2380 * error.h: adjust scm_syserror_msg prototype.
2381 * error.c (scm_syserror_msg): take an extra argument for errno.
2382 Using the global value didn't always work, since it could be
2383 reset by procedure calls in the message or args arguments.
2385 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
2386 I don't understand why the check was there (and what about the
2389 * strop.c (scm_string_copy): allow shared substrings to be copied.
2391 * unif.h: corresponding change to prototypes.
2392 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
2393 recognize two new optional arguments: offset and length. Allow
2394 the port argument to be an integer (file descriptor, for scsh).
2395 Include <unistd.h> for "read" prototype.
2397 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2399 * socket.c: don't include filesys.h.
2401 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
2403 * Makefile.am: add AWK=@AWK@ (?)
2405 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
2407 Add a rule to generate errnos.c from errnos.
2408 * error.c (scm_init_error): include errnos.c.
2409 * errnos_cnvt.awk: new file, converts the list of errno codes to
2411 * errnos_get.c: new file.
2412 * errnos.default: new file, contains errnos to try if they can't
2413 be extracted from errno.h.
2414 * configure.in: if using GCC, try and extract errno codes from
2418 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
2420 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
2421 * Makefile.am: Made libguile into a libtool library.
2422 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
2423 Set libtool_libs to indicate that libguile is a libtool library.
2424 See guile/ChangeLog for details.
2425 * .cvsignore: ignore "*.lo", the libtool library objects.
2427 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2429 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
2430 use htons in getservbyport argument.
2432 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2434 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
2435 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
2438 * objprop.c (scm_object_property): No need to take the CDR of the
2439 value returned by scm_object_properties, since Aug 20 change.
2441 * configure.in: When checking for struct linger, #include
2442 <sys/types.h> as well as <sys/socket.h>. I've never known
2443 <sys/types.h> to cause any portability problems, and Solaris's
2444 <sys/socket.h> needs it.
2445 * configure: Rebuilt.
2447 I think the Sun compiler has chosen a perverse way to interpret
2448 ANSI declarations combined with K&R definitions. We'll
2449 appease it a little bit. But when it invades France, we fight.
2450 * print.c (scm_iprlist): Change 'tlr' argument to an int.
2451 * print.h (scm_iprlist): Here too.
2452 * numbers.c (scm_divbigdig): Change definition to match
2453 declaration in numbers.h.
2454 * unif.c (scm_makflo): Change definition to match declaration in
2457 * init.c (scm_boot_guile): Don't return the value of
2458 scm_boot_guile_1. This function doesn't return a value;
2459 scm_boot_guile_1 doesn't return a value (or return at all).
2461 * eval.c (unmemocopy): Add a semicolon to appease the Sun
2464 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
2465 compile. I have a feeling this function is a bad idea anyway ---
2466 one should always test for features, not systems.
2468 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
2469 semicolons. Only pure luck kept this from being noticed earlier.
2471 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
2473 * socket.c (scm_recvfrom): Added missing semicolon.
2475 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2477 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
2478 the buffer and start and end positions for scsh networking
2481 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
2483 * configure.in: Revert previous change to this file; the problem
2484 is due to transient automake weirdness.
2485 * configure: Rebuilt.
2487 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
2488 PLUGIN/guile.libs. configure generates the latter from the former.
2489 * Makefile.in: Rebuilt.
2491 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
2492 need this if we install scripts, like guile-snarf.
2493 * configure: Rebuilt.
2495 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
2497 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
2499 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
2501 * socket.c (scm_addr_vector): fix faulty scm_listify.
2503 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
2505 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
2506 style block comment is no longer considered an error.
2508 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
2510 * PLUGIN/guile.libs.in: New file.
2511 * PLUGIN/guile.libs: Removed from repository.
2512 * configure.in: Create PLUGIN/guile.libs from
2513 PLUGIN/guile.libs.in. This is for including additonal libraries
2514 needed for dynamic linking.
2515 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
2516 instead of PLUGIN/guile.libs.
2518 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
2520 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
2522 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
2523 occurrences of the given element from the list, not just the
2524 first. This is how the Emacs Lisp functions behave, how the
2525 analogous Common Lisp functions behave, and (I believe) how the
2526 older Maclisp functions worked. I realize that this change may
2527 break code, but it seemed better to break it before the Guile
2530 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
2531 Their prototypes were already present in gc.h, but they weren't
2533 (scm_init_storage): Initialize scm_protects.
2534 * root.c (scm_protects): New element of scm_sys_protects.
2536 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
2538 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
2540 * libguile.h: Added #include "libguile/net_db.h".
2542 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
2543 30 change. That file is only meant for communication between the
2544 configuration process and load.c. If code linked against libguile
2545 wants to get at the paths mentioned in libpath.h, it can call
2546 functions declared in load.h.
2548 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2550 * libguile.h: Removed #include "libguile/fdsocket.h"
2552 * net_db.c: Added #include <sys/socket.h>.
2554 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
2556 * filesys.c (scm_input_waiting_p): use select in preference to
2557 FIONREAD, since the latter doesn't detect EOF.
2558 Throw error if neither select nor FIONREAD available.
2560 * socket.c (scm_connect): take a port, not a fd object.
2561 (scm_fill_sockaddr): throw an error if fam is not recognised.
2562 (scm_bind): use scm_fill_sockaddr.
2563 (scm_listen): take a port, not a fd object.
2564 (scm_accept): take and return a port. return #f in the car if
2565 address can't be got
2566 (scm_sock_fd_to_port): new procedure.
2567 (scm_socket): use scm_sock_fd_to_port.
2568 (scm_addr_vector): throw error if unrecognised address type.
2569 take an extra argument with the calling procedure name.
2570 (scm_getsockname): take a port. return #f if address can't be got.
2571 (scm_getpeername): take a port. return #f if address can't be got.
2572 (scm_recvfrom): take a port. return #f for address component if can't
2574 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
2575 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
2577 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
2579 * throw.c (scm_internal_catch): Make body funcs and handler funcs
2580 use separate data pointers, to allow them to be designed
2581 independently and reused.
2582 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
2583 Renamed from catch_body, catch_handler, and uncaught_throw; made
2585 (struct scm_catch_body_data): Renamed from catch_body_data; moved
2587 (scm_catch): Use the above.
2588 (scm_throw): Don't bother printing a message for an uncaught
2589 throw; we establish a default handler in init.
2590 * throw.h (scm_internal_catch): Prototype updated.
2591 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
2593 (struct scm_body_thunk_data): New structure, used as data
2594 argument to scm_body_thunk.
2595 * init.c (struct main_func_closure): New structure, packaging up
2596 the data to pass to the user's main function.
2597 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
2598 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
2599 scm_internal_catch to establish a catch-all handler, using
2600 scm_handle_by_message. This replaces the special-case code in
2602 (invoke_main_func): Body function for scm_internal_catch; invoke
2603 the user's main function, using the main_func_closure pointer to
2604 decide what to pass it.
2605 * root.c (struct cwdr_body_data): Remove handler_proc member.
2606 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
2607 (cwdr_handler): Removed.
2609 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
2611 * socket.h (SCM_P): update bind prototype.
2612 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
2613 include "feature.h".
2614 (scm_socket): return a port, not a file descriptor object.
2615 include "fports.h" and <unistd.h>
2616 (scm_bind): take a port, not a file descriptor object.
2617 take an extra argument for address args.
2619 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
2620 INADDR_NONE, INADDR_LOOPBACK.
2622 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
2624 * init.c: include net_db.h and not fdsocket.h.
2625 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
2627 * Makefile.am: corresponding changes.
2628 * socket.h: renamed from fdsocket.h, fix names.
2629 * net_db.h: renamed from socket.h, fix names.
2630 * socket.c: renamed from fdsocket.c.
2631 remove _sys from procedure names.
2632 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
2633 add "socket" to features list.
2634 * net_db.c: renamed from socket.c.
2635 remove _sys from procedure names.
2636 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
2637 add "net-db" to features list.
2638 include "net_db.h". don't include <sys/socket.h> or
2641 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2643 * tags.h (scm_tags): Removed comma at end of last enumerator.
2645 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
2647 Don't use GCC extensions to allocate space for debugging frames.
2648 (Here he goes again! Why do we put up with this?!)
2649 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
2650 an scm_debug_info structure, not an in-line array of them. Add
2651 'info' member, to say how many vect elements we've used, for eval
2653 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
2654 a new variable debug_info_end to mark the end of vect, instead of
2655 the address of the 'info' pointer itself.
2656 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
2657 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
2658 (SCM_APPLY): Explicitly allocate space for debug.vect.
2659 * debug.c (scm_m_start_stack): Same, for vframe.vect.
2660 * stacks.c: Adjusted for new debug frame structure.
2661 (RELOC_INFO, RELOC_FRAME): New macros.
2662 (stack_depth, read_frames): Use them, and new scm_debug_frame
2663 element 'info', instead of magically knowing that eval frames have
2664 an info pointer sitting after vect.
2665 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
2667 (scm_init_stacks): Formatting tweaks.
2669 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
2671 Give GCC more control flow information, so it can be sure that
2672 variables aren't used uninitialized.
2673 * error.h (scm_error, scm_syserror, scm_syserror_msg,
2674 scm_sysmissing, scm_num_overflow, scm_out_of_range,
2675 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
2676 scm_misc_error): Tell GCC that these functions never return.
2677 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
2678 out the field type, call abort if SCM_ASSERT returns, to placate
2680 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
2681 scm_wta ever returns. We can't handle this case anyway, and this
2682 gives the optimizer more information.
2683 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
2684 scm_wta ever returns.
2686 In some cases, the code is fine, but GCC isn't smart enough to
2687 figure that out; this usually happens when one variable is only
2688 initialized and used when a particular condition holds true, and
2689 we know that condition will never change within a given invocation
2690 of the function. In this case, we simply initialize the variables
2691 to placate the compiler, hopefully to a value which will cause a
2692 crash if it is ever actually used.
2693 * print.c (scm_iprin1): Initialize mw_pos.
2694 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
2695 * throw.c (scm_ithrow): Initialize dynpair.
2696 * unif.c (scm_uniform_vector_ref): Initialize cra.
2697 * struct.c (init_struct): Initialize prot.
2698 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
2700 * strports.c (scm_eval_0str): Don't return uninitialized garbage
2701 if EXPR contains no expressions.
2703 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2705 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
2706 cause an infinite loop (???). So much for the algebraic
2707 equivalency of variable-sized arrays and alloca...
2709 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
2711 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
2712 a SCM boolean, not a C boolean.
2714 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
2716 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
2717 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
2718 rules for raising scm_mtrigger. Previously, unfortunate but not
2719 unlikely circumstances could result in almost constant invokation
2720 of the gc. Now, this situations should be less likely, but they
2721 are not prevented completely.
2723 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
2725 * numbers.c (scm_fuck): Procedure removed; looks like old test
2727 * numbers.h: Prototype removed.
2729 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
2731 * debug.h (scm_debug_frame): Change `vect' member from an in-line
2732 array to a pointer, to match my Nov 21 change in eval.c.
2734 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2736 * libguile.h: Added #include "libguile/backtrace.h", #include
2737 "libguile/stacks.h".
2739 * strings.c (scm_string scm_make_string scm_string_ref
2740 scm_string_set_x scm_string_equal_p scm_string_append):
2741 Bugfix according to scm patch from Aubrey Jaffer:
2742 Corrected long-standing
2743 (not (eqv? (integer->char 128)
2744 (string-ref (make-string 1 (integer->char 128)) 0)))
2745 bug found by John Kozak <jk@noontide.demon.co.uk>.
2747 * strports.c, strports.h: Make scm_eval_0str return the value of
2748 the last expression evaluated (previously, it returned void).
2750 * strports.c, strports.h: New function: scm_read_0str. Does what
2753 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2755 * simpos.c (scm_getenv): return #f if string can't be found in the
2756 environment instead of throwing an exception, for compatibility
2757 with numerous other systems.
2759 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
2761 * Makefile.am (.c.x): Use guile-snarf.
2762 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
2764 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
2766 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
2768 * backtrace.c (scm_display_error_message): Made non-static, and
2769 renamed from display_error_message.
2770 * backtrace.h (scm_display_error_message): Added extern decl.
2771 * throw.c (uncaught_throw): Use it to display the error message.
2773 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
2775 * inet_aton.c: Use #if 0, not #ifdef 0.
2777 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
2779 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
2780 to convert the returned value.
2781 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
2782 the offset argument.
2784 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
2786 Add new interface to catch/throw, usable from C as well as
2788 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
2789 (scm_internal_catch): New function, replaces...
2790 (scm_catch_apply): Deleted.
2791 * throw.c (scm_catch_apply): Deleted; replaced with a more general
2792 mechanism which is a bit more code, but can be used nicely from C
2793 and implement the Scheme semantics as well.
2794 (scm_internal_catch): This is the replacement; it's named after
2795 the analogous function in Emacs.
2796 (scm_catch): Reimplemented in terms of the above.
2797 (struct catch_body_data, catch_body, catch_handler): New
2798 functions, used by scm_catch.
2799 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
2800 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
2801 support for new cwdr.
2803 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
2806 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
2808 * acconfig.h: Added DYNAMIC_LINKING symbol.
2809 * configure.in: Add option and checks for dynamic linking.
2810 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
2811 dynl.h: New files for dynamic linking support.
2812 * Makefile.am (libguile_a_SOURCES):
2814 (modinclude_HEADERS): Added "dynl.h".
2815 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
2817 * init.c (scm_boot_guile_1): Call
2818 scm_init_dynamic_linking to initialize dynamic linking support.
2820 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
2822 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
2823 (as we Schemers say). It needs to be global, so that I can tweak
2824 it for the proper operation of unexec.
2825 (scm_boot_guile_1_live): New variable, see above.
2827 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
2829 * guile-snarf.sh: Removed.
2830 * PLUGIN/guile.libs: Added dependency for -lm.
2831 * acinclude.m4: Renamed from aclocal.m4.
2832 * PLUGIN/greet: Removed.
2833 * Makefile.am, aclocal.m4: New files.
2834 * configure.in: Updated for Automake.
2836 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
2838 * eval.c (scm_definedp): Use top_level_lookup_closure_var
2839 and not top_level_lookup_thunk_var.
2841 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
2843 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
2845 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
2847 * eval.c (scm_definedp): Incompatibly changed to be a builtin
2848 Scheme function, instead of syntax. Single argument is now a
2851 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2853 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
2854 scm_ra_divide): Properly terminate statements passed as arguments
2855 to IVDEP macros. (Thanks to Bernard Urban.)
2857 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
2858 with non-constant sizes. (Thanks to Bernard Urban.)
2860 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
2862 It's an "eval closure", not an "eval thunk." A thunk is a
2863 function of no arguments.
2864 * root.h (struct scm_root_state): Renamed
2865 top_level_lookup_closure_var from top_level_lookup_thunk_var.
2866 (scm_top_level_lookup_closure_var): Renamed from
2867 scm_top_level_lookup_thunk_var.
2868 * root.c (mark_root): Uses changed.
2869 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
2870 * init.c (scm_start_stack): Uses changed.
2871 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
2872 Change scheme-visible name to *top-level-lookup-closure* from
2873 *top-level-lookup-thunk*.
2875 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
2877 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
2878 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
2880 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
2882 * gc.c (struct scm_heap_seg_data): Doc fixes.
2884 * gc.c (scm_gc_sweep): Empty all segments' freelists before
2885 sweeping. Then, prepend each segment's free cells to its
2886 freelist, rather than wiping out the old value. (Thanks to Marius
2889 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
2890 scm_check_freelist, scm_debug_newcell): New functions and
2891 variables, for debugging freelist problems.
2892 * pairs.h (SCM_NEWCELL): New debugging version added.
2893 * gc.h (scm_debug_newcell): Added extern declaration, used by
2894 debugging version of SCM_NEWCELL.
2896 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2898 On some systems <libc.h> conflicts with <unistd.h>, and should not
2899 be #included at all.
2900 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
2901 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
2902 * configure.in: Call it.
2903 * posix.c, filesys.c: Use its results to decide whether or not to
2905 * configure, scmconfig.h.in: Rebuilt with autoconf and
2908 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2910 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
2911 pointer to the stdio stream before calling scm_setbuf0, so the
2912 latter will be able to retrieve it. I'm surprised this didn't
2913 segfault earlier. (Thanks to Christopher Lee.)
2915 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2917 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
2920 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2922 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
2923 number of stack narrowing specifier pairs. The first specifier in
2924 a pair controls inner border, the second the outer border. A
2925 number means cut that number of frames, a procedure object means
2926 cut until that object is found in operator position in a frame.
2928 * root.c (cwdr): Bugfix.
2930 * read.c: Recording of positions disabled by default.
2932 * procs.c (scm_closure_p): New function.
2934 * posix.c (scm_tmpnam): New function.
2936 * load.c: Added #include "throw.h".
2937 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
2940 * load.c, load.h (scm_read_and_eval_x): New function.
2942 * eval.c: Renamed debug option "deval" to "debug".
2944 (scm_eval_x): `eval!' is no longer accessible from the scheme
2945 level. Motivation: We can't allow operations which introduce
2946 glocs into the scheme level. Guile's type system can't handle
2947 these as data. Use `eval' or `read-and-eval!' as replacement.
2949 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
2950 SCM_CONSP since this is a macro!; Set vframe.prev to
2951 scm_last_debug_frame instead of 0. In this way we can look
2952 "above" the virtual start stack frame if we wish.
2953 (scm_debug_hang): New function: Useful for debugging Guile in
2954 certain tricky situations. Will probably be removed later...
2956 * debug.h: Changed semantics of debug option "backtrace". This
2957 option now only indicates whether we want automatic backtrace at
2960 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2962 * ports.c: #include "filesys.h"
2963 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
2965 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
2966 Motivation: This is system specific code which is related to file
2967 I/O. It also may use select. Added code by Gary Houston to
2968 detect presence of character in stdio buffers.
2970 * libguile.h: #include "libguile/libpath.h"
2972 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
2973 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
2974 SCM_SITE_DIR; Install libpath.h among the other include files.
2976 * load.c, load.h (scm_sys_package_data_dir): New function.
2978 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2980 * stacks.h: Bugfix: Don't use tail-array length field as stack
2981 length field! This screwed GC.
2983 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2985 * _scm.h: Added #ifndef around definition of macros min and max.
2987 * __scm.h: Added hooks for threads to plugin to in ints protection
2988 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
2989 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
2990 the main code in these macros duplicated and spread over multiple
2991 files. Renamed SCM_THREADS_SWITCHING_CODE ->
2992 SCM_THREAD_SWITCHING_CODE.
2994 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
2996 * snarf.h: New file.
2997 * guile-snarf.sh: New file.
2998 * Makefile.in (inner_h_files): Added snarf.h
2999 (ancillary, install, uninstall, distclean): Added actions for
3001 (.c.x): Use guile-snarf.
3002 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
3003 (gen_c_files): Note that these depend on guile-snarf.
3004 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
3005 now in "snarf.h". Added #include "snarf.h" to get them.
3006 * libguile.h: Added #include "snarf.h".
3007 (Patches applied and tweaked by Jim Blandy.)
3009 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3011 * socket.c: Use K&R style declaration for 'close'; the GNU coding
3012 standards suggest against providing prototypes for system
3013 functions. Thanks to Greg Troxel.
3015 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3017 * strports.c (scm_eval_0str): New function.
3018 #include "read.h", to get prototype for scm_read.
3019 * Makefile.in (strports.o): Update dependencies.
3020 * strports.h: New prototype.
3022 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
3023 scheme name from "int?" to "integer?". It seems to do the job.
3024 * numbers.h: Rename prototype too.
3025 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
3028 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
3029 scm_num_eq_p): Rename these according to R4RS conventions: call
3030 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
3031 to making libguile R4RS compliant without ice-9...
3033 * load.c (scm_sys_search_load_path): Search for files under all
3034 extensions listed in the %load-extensions variable. If FILENAME
3035 is absolute, return it unchanged, without searching the load path.
3036 (scm_loc_load_extensions): New variable, pointing to
3037 %load-extensions' value cell.
3038 (scm_init_load): Initialize it, and the value it points to.
3039 (scm_primitive_load_path): Improve error reporting.
3041 * load.c (scm_loc_load_hook): New variable, pointing to value cell
3042 of new Scheme variable %load-hook.
3043 (scm_primitive_load): Apply %load-hook to filename.
3045 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
3047 * configure.in: add tests for figuring out whether buffered data
3048 is available in a FILE structure, which is needed by char-ready.
3050 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
3053 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
3054 exceptions using misc_error instead of syserror. It seems a bit
3055 odd to throw an exception if a string can't be found in the
3056 environment, but it's consistent with open-file, stat etc.
3057 (simpos.h): remove sys_ from getenv.
3059 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
3060 occurs, throw an error instead of returning errno. Return value
3062 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
3064 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
3066 * filesys.c (scm_stat2scm): derive file type and permissions from
3067 the stat mode and append them to the returned vector.
3068 There isn't much overhead in doing this and it avoids the need to
3069 work with S_IRUSR et al. in Scheme.
3070 Define symbols scm_sym_regular etc.
3071 (scm_init_filesys): don't intern S_IRUSR etc.
3073 * load.c: change s_try_load and s_try_load_path to s_primitive_load
3074 and s_primitive_load_path.
3076 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
3078 * error.h: don't declare error symbols. prototype for scm_misc_error.
3080 * stackchk.c (scm_stack_overflow_key): defined here instead of in
3083 * error.c: use SCM_SYMBOL to set up error keys.
3084 scm_misc_error: new procedure.
3086 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3088 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
3089 between `#!' and `!#' is ignored.
3090 (skip_scsh_block_comment): New function.
3092 * feature.c (scm_set_program_arguments): New argument, FIRST.
3093 * feature.h: Update prototype.
3094 * init.c (scm_boot_guile_1): Pass new argument to
3095 scm_set_program_arguments.
3097 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3099 * init.c (scm_start_stack): Don't initialize scm_progargs here.
3100 (scm_boot_guile): Call scm_set_program_arguments here, later than
3101 the old initialization.
3103 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
3104 initialization procedure.
3105 - Delete in, out, err arguments; there are other perfectly good
3106 ways to override these when desired.
3107 - Delete result argument; this function shouldn't ever return.
3108 - Rename init_func argument to main_func, for less confusion.
3109 - Delete boot_cmd argument; main_func is more general.
3110 -Add 'closure' argument, to help people pass data to main_func
3111 without resorting to global variables.
3112 - Abort if reentered; don't bother returning an error code.
3113 - Call scm_init_standard_ports to set up the default/current
3114 standard ports; no need to pass them to scm_start_stack.
3115 - Remove code to evaluate the boot_cmd, and start the repl; let
3116 the user do something like that in main_func if they want.
3117 - Remove code to package up a return value; main_func can do any
3119 - Call exit (0), instead of returning.
3120 (scm_start_stack): Don't initialize the I/O ports here; that's
3121 weird. Delete in, out, err arguments. Move guts to
3122 scm_init_standard_ports, scm_stdio_to_port.
3123 (scm_init_standard_ports): New function, to set up current and
3124 default standard ports.
3125 (scm_start_stack, scm_restart_stack): Make these static.
3126 * init.h (scm_boot_guile): Adjust declaration.
3127 (scm_start_stack, scm_restart_stack): Remove externally
3128 visible declarations for these.
3129 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
3131 * fports.c (scm_stdio_to_port): New function. Its guts used to be
3132 written out several times in scm_start_stack.
3133 * fports.h: New declaration for the above.
3135 * feature.c (scm_set_program_arguments): New function.
3136 * feature.h: New declaration for the above.
3138 * ports.c: Formatting tweak.
3140 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
3142 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
3143 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
3144 for obtaining the address of a car or cdr field. Motivation:
3145 &SCM_CXR make assumptions about the internal structure of the
3148 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
3149 Motivation: see SCM_CXRLOC.
3151 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
3152 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
3153 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
3154 Motivation: Safer use. Some other macros are defined in terms of
3155 these operations. If these are defined using the SCM_SETCXR
3156 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
3157 to inefficiency and an <e1> with side-effects could potentially
3158 break. Also, these particular operations are heavily utilized in
3159 the garbage collector. In unoptimized code there will be a
3162 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
3163 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
3164 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
3165 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
3166 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
3167 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
3168 vports.c: Cleaned up use of pairs: Don't make any special
3169 assumptions about the internal structure of selectors and
3170 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
3171 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
3172 (Among other things, this change makes it easier to build Guile
3173 with certain compilers which have problems with casted lvalues.)
3175 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3177 * stacks.c: Improve selection of relevant stack frames when making
3178 a stack object. Introduce one level of indirection in the stack
3179 object to make it possible to "narrow" to a certain region of the
3180 stack. This facilitates making use of more clever algorithms (not
3181 implemented) for selecting relevant frames and gives a cleaner
3182 design since selection of frames can be done independently of
3183 extraction of frames from the real stack.
3184 (scm_stack_id): Also take #t as argument which means look at
3187 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
3188 Turn n_tail into an integer directly representing current number
3189 of frames in stack. Add field tail.
3191 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
3193 * debug.c (scm_make_memoized): Made it available at scheme level.
3194 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
3195 SCM_NIMP before applying heavier predicates in argument checking.
3196 (scm_local_eval): Also take memoized object as argument.
3198 * backtrace.c (scm_display_error): Just a safety measure: Stacks
3199 aren't created with zero length, but should such a strange
3200 creature suddenly turn up...
3202 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
3204 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
3205 `del', for the sake of C++ compilers. (Patch applied by JimB.)
3207 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
3209 * variable.c (scm_make_variable): Make the name hint optional, as
3211 (anonymous_variable_sym): Renamed from variable_sym. All uses
3214 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
3215 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
3216 of scm_primitive_load_path was also changed to
3217 "primitive-load-path", from "%try-load-path". Callers changed.
3218 We'd like to respect the convention that a function named
3219 "try-mumble" should behave just like the function called "mumble",
3220 but return #f instead of signalling some error.
3221 * load.h: Rename prototypes.
3223 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3225 * print.c (make_print_state, grow_print_state), print.h: Modified
3226 the print state representation: Don't use a tail array for
3227 recording of circular references. Resizing of the print state
3228 structure invalidates the print state pointer. To avoid passing
3229 around an indirect print state reference to all printing
3230 functions, we instead let the print state reference a resizable
3233 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
3235 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
3236 Don't crash when passed an improper list terminated by a
3237 non-immediate value.
3239 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
3241 Allocate data for structures on an eight-byte boundary, as
3242 required by the tagging system.
3243 * struct.c (alloc_struct): New function.
3244 (scm_make_struct, scm_make_vtable_vtable): Call it.
3245 * struct.h (scm_struct_n_extra_words): Bump to 3.
3246 (scm_struct_i_ptr): New "field".
3247 * gc.c (scm_gc_sweep): When we need to free the data, use the
3248 information stored by alloc_struct to find the beginning of the
3249 block allocated to the structure, so we can free it.
3251 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3253 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
3256 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
3257 (scm_debug_info): New member: id.
3259 * stacks.c: Stacks are now represented as structs; Stacks have an
3260 id given to them by `start-stack'.
3261 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
3263 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
3264 Changed stack representation.
3266 * debug.c (scm_procedure_name): Try procedure property `name' for
3267 compiled closures aswell.
3269 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
3271 * eval.c: scm_i_name moved to gsubr.c
3272 (scm_m_define): Record names of all kinds of procedure
3273 objects. (Earlier, only closures were recorded.)
3275 * procprop.h: Added declaration of scm_i_name.
3277 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
3278 (scm_make_gsubr): Record names of compiled closures.
3280 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3282 * debug.c, debug.h: Removed obsolete code.
3284 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
3285 stacks.c: Renamed regs --> scm_contregs.
3287 * print.c (scm_free_print_state): Cleanup print state before
3288 returning it to pool. It is better to do it here than in
3289 scm_prin1 since scm_prin1 is called often.
3291 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
3292 s_set_source_property_x): Check that first argument is a pair or a
3295 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
3296 scm_i_line, scm_i_column and scm_i_breakpoint global.
3298 * init.c: Added #include "backtrace.h" and #include "stacks.h".
3299 (scm_boot_guile_1): Added calls to scm_init_backtrace and
3302 * debug.h: Added debug object smob declaration and macro
3305 * configure.in: Build with backtrace.o and stacks.o if debug
3308 * Makefile.in: Added entries for new files: backtrace.c,
3309 backtrace.h, stacks.c and stacks.h.
3311 * symbols.c (scm_sym2ovcell): Fixed documentation.
3313 * _scm.h (min, max): Added.
3315 * async.c: Moved `min' macro to _scm.h.
3317 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
3318 SCM_BACKTRACE_INDENT.
3320 * eval.c: Added new debug options `maxdepth' and `indent'.
3322 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
3324 * print.h: Added selector SCM_PRINT_STATE.
3326 * print.c: New functions: scm_make_print_state,
3327 scm_free_print_state.
3329 * print.h: Added declarations for scm_make_print_state,
3330 scm_free_print_state.
3332 * debug.c (scm_m_start_stack): New acro.
3334 * debug.h: Small cleanup.
3336 * init.c (scm_boot_guile_1): Moved scm_init_debug below
3339 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
3341 * __scm.h, alist.c, alist.h, append.c, append.h, appinit.c,

3364 More prototype-related changes from Marius Vollmer:
3365 * gdb_interface.h: Wrapped header file in #ifdef/#endif
3366 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
3367 * ports.h (ptobfuns): Added prototypes. This means some casting in
3369 * fports.c: Added casts for initializations, since the functions
3370 are defined to take FILE * as their stream argument, not SCM.
3371 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
3372 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
3373 to `char *str_data' to conform to prototype.
3375 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
3377 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
3379 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
3381 * stime.c, stime.h: use SCM_P method.
3383 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
3385 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
3386 be given at least two arguments. Insist that lst's last element
3387 be a list, but don't make any requirements of its predecessors.
3389 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
3391 * eval.c (scm_nconc2last): Revert last change; there seems to be
3392 other stuff going on here.
3394 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
3396 * eval.c (scm_nconc2last): Make sure that each element of lst
3397 (which is a list of argument lists, except for the tail) is a
3398 proper list, i.e., finite and terminated by '().
3400 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3402 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
3405 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
3406 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
3409 * vectors.c (scm_make_vector): Fill vectors with the undefined
3410 value, to help make Guile Scheme code more portable to other
3413 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
3414 * symbols.h, tags.h: Doc fixes.
3416 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
3418 * async.c (scm_take_signal): Doc fixes.
3420 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
3422 * numbers.c (scm_divbigint): When the remainder is zero, we don't
3423 want to subtract it from the modulus; we just want to leave it
3426 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
3428 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
3431 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
3433 * throw.c (scm_catch_apply): Finished implementation of
3436 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
3438 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
3440 (scm_init_filesys): set "i/o-extensions" feature.
3443 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
3445 * Makefile.in (root.o): Correct dependencies.
3447 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
3449 * Makefile.in: Added dependency entry for root.o.
3451 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
3452 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
3454 * init.c (scm_start_stack): Set initial root continuation number
3457 * procs.c: New function: scm_thunk_p.
3459 * procs.h: Added declarations of scm_thunk_p.
3461 * root.c: Renamed `call-with-new-root' -->
3462 `call-with-dynamic-root'.
3463 (cwdr): Removed allocation of new root state. This should be done
3464 separately by use of scm_make_root.
3465 (scm_apply_with_dynamic_root): New function: Does what it
3466 sounds like. Needed when spawning threads.
3468 * root.h: Added member last_debug_frame to root state.
3469 Added #include "libguile/debug.h"
3471 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
3472 arguments. The motivation is that code in root.c needs catch
3473 functionality, and we want to avoid code duplication.
3474 New functions: scm_catch, scm_lazy_catch. These are wrappers for
3475 scm_catch_apply. scm_lazy_catch is intended to introduce catch
3476 handlers that run without popping the stack into the dynwind
3479 * throw.h: Added prototypes for scm_catch_apply and
3482 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3484 * root.h (scm_root, scm_set_root): Decouple thread support details
3485 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
3486 SCM_SET_THREAD_LOCAL_DATA.
3488 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
3489 and tortoise scanning loop.
3491 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
3493 * Makefile.in: Rebuild dependencies.
3495 * libguile.h: #include "libguile/print.h" before "smob.h", since
3496 the latter uses the print_state structure.
3498 * throw.c (scm_ithrow): Use the correct variable when checking to
3499 see if a given element of scm_dynwinds is a valid catch.
3501 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
3502 structure, abort; don't just silently ignore the garbage.
3504 * _scm.h: #include "print.h" here, since it seems to be used just
3506 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
3507 strports.c, unif.h: Don't #include "print.h".
3509 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3511 * feature.h (scm_loc_features): Removed external declaration.
3512 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
3514 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3516 * feature.c (scm_init_feature): Added threads feature (needs to be
3517 initialized here, since features doesn't exist when
3518 scm_init_threads is called).
3520 * libguile.h: Added #include "libguile/../threads/threads.h".
3521 (This is a kludge to get thread support working. This should be
3524 * configure.in, acconfig.h: Added flags for thread support.
3526 * scmsigs.c: Define `signal' to be `pthread_signal' if using
3529 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
3530 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
3533 * _scm.h: Added conditional #include "threads.h"
3535 * __scm.h (SCM_ASYNC_TICK): Added call to macro
3536 SCM_THREADS_SWITCHING_CODE.
3538 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
3539 allocate the basic dynamic root object.
3540 (scm_boot_guile): Added call to scm_init_root.
3542 * root.c, root.h: Added root smob.
3543 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
3544 functions: Implements dynamic roots mostly according to spec in
3545 SCM manual. Main difference is that the second argument is a
3546 throw handler rather than an error "thunk".
3548 * root.h: Added declaration of scm_init_root.
3550 * root.c: Added #include "genio.h", #include "smob.h", #include
3551 "pairs.h", #include "throw.h", #include "dynwind.h", #include
3553 (scm_init_root): Added #include "root.x".
3555 * throw.c: Added #include "stackchk.h"
3556 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
3557 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
3558 can be used in scm_call_with_new_root; Added reenabling of stack
3559 checking when catching a throw.
3561 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
3563 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
3565 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
3566 element is not found, as per R4RS.
3568 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
3570 * list.c: Doc fixes throughout.
3572 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3574 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
3575 declare the char * to be const. Avoids a warning in rgx.c.
3577 * ports.h: spelling fix.
3579 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
3582 * load.c (scm_sys_try_load_path): throw an error if file not found
3583 (like it says it in NEWS).
3585 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
3587 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
3588 PROPS slot to '(), not #f; it's an empty alist.
3590 * throw.h, throw.c: Use SCM_P instead of #if hair.
3592 Remove special support for uncaught throws; see throw.c for
3594 * throw.c (uncaught_throw): New function.
3595 (scm_ithrow): Call uncaught_throw if we don't find a throw
3596 target; don't mess with scm_bad_throw_vcell.
3597 (scm_bad_throw_vcell): Variable deleted.
3598 (scm_init_throw): Don't initialize it.
3600 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
3603 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3605 * numbers.c (scm_istr2int): If the number is short (as most
3606 numbers are), just call scm_small_istr2int to deal with it.
3607 (scm_small_istr2int): New function, created by un-#ifdefing the
3608 non-bignum version of scm_istr2int and renaming it.
3610 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
3612 * load.c (scm_sys_try_load): don't check whether value returned
3613 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
3614 Change the Scheme name from %try-load to primitive-load.
3616 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
3617 Can avoid passing a message, allowing it to be derived in the
3618 error handler (e.g., if we want to throw to the key both from
3621 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
3623 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
3624 references now have a new appearance which is more compact and
3625 also gives a clue about what the target of the reference is.
3626 By setting parameters in the print state, more fancy printing can
3627 be achieved. This is used by the (not yet commited) backtrace
3630 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
3632 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
3635 * print.c: Added #include "struct.h". Removed function
3638 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
3639 scm_iprin1. Removed prototype for scm_prlist.
3641 * arbiters.c (prinarb),
3642 async.c (print_async),
3643 debug.c (prindebugobj, prinmemoized),
3644 eval.c (prinprom, prinmacro),
3645 filesys.c (scm_fd_print, scm_dir_print),
3647 mallocs.c (prinmalloc),
3648 numbers.c, numbers.h (scm_floprint, scm_bigprint),
3649 smob.h (scm_smobfuns),
3650 srcprop.c (prinsrcprops),
3652 unif.c, unif.h (scm_raprin1, rapr1),
3653 variable.c (prin_var): Changed argument `int writing' to
3654 `scm_print_state *pstate'.
3656 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
3657 that it will be called before scm_init_print.
3659 * print.c (scm_prin1): Print states are now allocated when calling
3660 scm_prin1 and then passed around to all printing functions as an
3661 argument. A cache `print_state_pool' enables reuse of print
3663 (scm_make_print_state): New function.
3664 (scm_iprin1): Adaption to print states.
3665 (scm_iprlist): An initial "hare and tortoise" scan brings down
3666 time complexity to O (depth * N). (Better time complexity will be
3667 achieved when the printing code is completely rewritten.)
3669 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3671 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
3672 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
3673 it gets done whether or not the cache variable has a value.
3675 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3677 Distinguish #f and ().
3678 * __scm.h: #undef SICP.
3679 * pairs.h (SCM_EOL): Delete this definition, equating it with
3681 * tags.h (SCM_EOL): Give it a new definition here; I think I found
3682 the value it used to have. Doc fixes, too.
3684 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
3686 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
3687 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
3688 Lord's implementation of structs, allowing for tail arrays as
3689 described in the manual. Also fixed some bugs. (Both the interface
3690 and the implementation should be improved.)
3692 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
3694 * print.c, print.h: Closures now print like #<procedure foo (x)>.
3695 People who whish to see the source can do `(print-enable 'source)'.
3696 Removed #ifdef DEBUG_EXTENSIONS.
3698 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
3700 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
3701 integer (assuming for now accepting an integer is a good thing).
3703 * error.c, fports.c: replace use of %S in lgh_error args with %s.
3704 %S will be used instead for write'ing arguments.
3706 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
3707 asserts. fix a few other asserts.
3708 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
3709 scm_uniform_vector_ref, scm_array_set_x,
3710 scm_dimensions_to_unform_array): change args in
3711 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
3712 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
3713 scm_substring_fill_x): likewise.
3714 gsubr.c (scm_gsubr_apply): likewise.
3715 eval.c (SCM_APPLY): likewise.
3717 * eval.c (4 places): replace scm_everr with lgh_error or
3720 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
3721 scm_memory_error): new procedures.
3722 scm_everr: deleted. can use scm_wta, dropping first two args.
3723 scm_error: convert NULL subr to SCM_BOOL_F.
3725 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
3728 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
3731 * error.c, error.h: new error keys: scm_arg_type_key,
3732 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
3734 scm_wta: reimplement using lgh_error instead of scm_everr.
3736 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
3738 * gdbint.c: scm_lread now has one more argument.
3740 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
3741 scm_port_\1; Added mutator scm_set_port_filename_x (used when
3742 loading source from non-file ports, which, e. g., happens when
3743 using the Emacs interface).
3745 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
3748 * read.c: Added code for recording of positions of source code
3749 expressions; New functions: recsexpr, scm_lreadrecparen;
3750 _scm_make_srcprops --> scm_make_srcprops
3751 (scm_flush_ws): Removed updating of positions counters. This work
3752 is already done by scm_gen_getc
3754 * read.h: Added prototype for scm_lreadrecparen
3756 * print.c: Added #include "alist.h"
3758 * eval.c: Added #include "hash.h"
3760 * eq.c: Added #include "ramap.h"
3762 * options.c: Documentation fixes.
3764 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
3765 (scm_init_srcprop): Adjusted size of initial source-whash. Name
3766 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
3767 --> scm_make_srcprops
3769 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
3770 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
3771 function calls in the definition of the whash access macros.
3773 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
3775 * init.c (scm_boot_guile): Add level of indirection to
3776 scm_boot_guile_1() to ensure that stack base pointer is properly
3777 initialized. There was no guarantee that variable i was the
3778 highest/lowest variable on stack (i.e. the call frame of
3779 scm_boot_guile was not completely protected from gc).
3781 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
3783 * ports.h (scm_port_table): put back file_name, it will be used to
3784 support debugging. Undo related changes in fports.c, ioext.c,
3787 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
3789 * ports.h (scm_port_table): remove file_name member for now, it seems
3791 * fports.c (scm_open_file): don't set file_name in PTAB.
3792 (prinfport): don't use file_name in PTAB.
3793 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
3794 * ports.c (scm_add_to_port_table): don't intialize file_name.
3795 (scm_port_file_name): remove for now.
3796 * gc.c (scm_gc_mark): don't mark PTAB file_name.
3798 * fports.h (scm_mkfile): prototype deleted.
3799 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
3801 * debug.c, unif.c: use scm_out_of_range instead of
3802 wta for range errors (ASSERT still needs work).
3804 * error.c, error.h (scm_out_of_range): new procedure.
3806 * error.c, error.h (scm_out_of_range_key): new key.
3808 * posix.c (scm_sync): #else was missing.
3810 * error.c, error.h: append _key to names scm_num_overflow and
3813 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
3814 of consing an empty list.
3815 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
3816 of macros, saves code and string space.
3817 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
3818 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
3819 lower case. Rename scm_syserror_m to scm_syserror_msg.
3820 error.h: prototypes for new procedures.
3822 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
3824 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
3826 * error.c, error.h: setup scm_num_overflow key.
3828 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
3829 Remove definition of SCM_OVSCM_FLOW.
3831 * fports.c (scm_open_file): use SCM_SYSERROR_M.
3833 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
3834 explicit message and args.
3836 * error.c, error.h, __scm.h: change system_error_sym to
3839 * error.c (system_error_sym): remove leading %% from the Scheme name
3842 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
3844 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3846 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
3847 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
3848 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
3849 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
3850 renamed. (These were introduced by unsupervised name
3853 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3855 * print.c: Added code for detection of circular references during
3856 printing. (init_ref_stack, grow_ref_stack): New functions. Added
3857 a hook for printing of closures (accessible via print options).
3858 This leads to a split of calls to scm_iprin1 into two classes:
3859 elementary print operations (e. g. the code which prints a smob)
3860 still use scm_iprin1 while top level calls (like scm_display) use
3861 scm_prin1. scm_prin1 begins by clearing the data structure used
3862 to record reference information.
3864 * print.h: Added declarations of scm_prin1 and scm_prlist.
3866 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
3868 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
3870 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
3872 * error.c (err_head): scm_iprin1 --> scm_prin1
3874 * debug.c: Adjusted header comment.
3878 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
3880 * strerror.c: Doc fix.
3882 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3884 * gdbint.c (gdb_read): Now possible to run during GC.
3885 (unmark_port, remark_port): New functions.
3887 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
3889 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
3890 of allocating a new string object. Also, increase size by
3891 the factor 2 instead of 1.5.
3893 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
3895 * __scm.h (SCM_P): Corrected to run under traditional C.
3897 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
3900 * async.c: Calls to scm_sysintern corrected.
3902 * async.h (scm_async_clock): Redundant declaration removed.
3904 * continuations.c (scm_dynthrow): Redundant declaration removed.
3906 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
3907 Definition typos corrected.
3909 * debug.h: Missing declarations of functions in debug.c added
3912 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
3913 Missing declarations to functions in eval.c added.
3915 * filesys.c: Possibly uninitialized variable rv.
3917 * gc.h (scm_object_addr, scm_unhash_name): Missing
3918 declarations of functions defined in gc.c added.
3920 * genio.c: Possible typos str_data -> wstr_data. ???
3922 * genio.c: Possibly unintended shadowing of local variable
3923 `int c' (gotos out of scope of inner `c'). ???
3925 * init.c: Uninitialized `SCM last' may be used.
3927 * ioext.h: (scm_sys_isatty_p): Typo.
3929 * list.h (scm_list_head): Missing prototype for function in
3932 * numbers.c (scm_two_doubles): Changed from extern to static
3933 (is used only within numbers.c).
3935 * numbers.h: Repeated declarations removed.
3937 * ports.h (scm_close_all_ports_except): Declaration for the
3938 function defined in ports.c added.
3940 * posix.h: Missing declarations added.
3942 * procs.h (scm_make_subr_opt): Missing declaration added.
3944 * socket.h (scm_sys_gethost): Missing declaration added.
3946 * socket.h: Redundant declarations removed (they are in fdsocket.h).
3948 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
3949 Missing declarations added.
3951 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
3953 * struct.c: Uninitialized variable `SCM answer' may be used.
3955 * unif.c (l2ra): Declaration prototype.
3957 * unif.c (scm_array_equal_p): Dummy definition removed (it is
3958 defined in ramap.c).
3960 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
3961 Redundant declarations removed (they are in ramap.h).
3963 * variable.h (scm_make_udvariable,
3964 scm_make_undefined_variable): Declaration corrected to
3965 correspond variable.c.
3967 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
3968 Missing declarations added.
3970 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
3972 * Makefile.in (distclean): Don't forget to delete fd.h.
3974 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3976 * fd.h.in, tags.h: Trivial cleanups.
3978 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
3979 marksweep.h just declared functions from gc.c.
3980 * gc.h, libguile.h: Don't #include "marksweep.h".
3981 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
3982 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
3983 dependencies updated.
3985 * libguile.h: Don't #include "files.h"; it's been deleted.
3987 * files.c (scm_sys_delete_file): Moved to filesys.c.
3988 File is now empty; deleted.
3990 * filesys.c: scm_sys_delete_file is now here. Remove
3991 #if's; they seem to rely on remnants of an old portability
3992 regimen. If the problems come up again, solve them properly,
3993 using autoconf. Specifically: Don't test M_SYSV, and #define
3994 remove to be unlink if it's #defined; don't use remove just
3995 because HAVE_STDC_HEADERS is #defined.
3996 * filesys.h: Add declarations for scm_sys_delete_file.
3997 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
3998 files.o, files.h, files.c, and files.x.
3999 * init.c: Don't #include "files.h", and don't call scm_init_files.
4001 Use SCM_P instead of PROTO; the latter intrudes on the user's
4003 * params.h: Deleted; definition of SCM_P moved to...
4004 * __scm.h: ... here, where it replaces PROTO macro.
4005 * libguile.h, smob.h: Don't #include "params.h".
4006 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
4007 smob.h: Fix prototypes accordingly.
4008 * Makefile.in: Update dependencies.
4009 (inner_h_files): Remove params.h.
4011 * gc.c: #include "gc.h"; every module should include its header,
4012 to let the compiler cross-check the declarations against the
4015 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
4016 simpos.h: #include "libguile/__scm.h".
4018 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
4020 * init.c: Don't forget to #include smob.h and init.h.
4021 * Makefile.in: Dependencies updated.
4023 * smob.h: Use PROTO instead of #if __STDC__.
4025 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
4027 * __scm.h: Doc fixes.
4029 * __scm.h, libguile.h: Use "quotes" in the #includes, not
4030 <angles>; this allows `make depends' to work properly.
4032 * libguile.h: #include smob.h and pairs.h before the others; they
4033 define typedefs used by other headers.
4035 C files should #include only the header files they need, not
4036 libguile.h (which #includes all the header files); the pointless
4037 recompilation was wasting my time.
4038 * Makefile.in (all .o dependency lists): Regenerated.
4039 * libguile.h: Don't try to get a definition for size_t here...
4040 * __scm.h: Do it here.
4041 * _scm.h: Since this is the internal libguile header, put things
4042 here that all (or a majority) of the libguile files will want.
4043 Don't #include <libguile.h> here; that generates dependencies on
4044 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
4045 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
4046 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

4143 * weaks.c: Get "weaks.h".
4145 * stackchk.h: #include "libguile/debug.h",
4147 * print.h, read.h: #include "options.h", since everyone who uses
4148 either of these files will need that.
4150 * smob.h: #include "ports.h", "genio.h", and "print.h", since
4151 anyone who uses this file will need them to define the smob
4152 printing functions. Also, get markers.h, since people will need
4153 to #define the mark functions.
4155 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
4156 * ports.h: ... to here.
4158 * ports.h (scm_port_table_size): Explicitly give type as 'int';
4159 don't rely on archaic C default type rules.
4161 * fports.h: #include "libguile/ports.h", since you need that in
4162 order to parse this.
4164 * genio.h: #include "libguile/print.h", because you need that to
4165 parse this; don't bother #including "ports.h", since print.h gets
4168 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
4170 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
4171 this; it's now a reference to an element of *scm_root.
4173 * debug.h: Don't #include "options.h"; the compiler won't be able
4174 to find that once the headers are installed; instead, #include
4175 "libguile/options.h".
4176 * gc.h: Same, with marksweep.h.
4177 * mbstrings.h: Same, with symbols.h.
4178 * scmhob.h: Same, with _scm.h.
4179 * smob.h: Same, with params.h.
4181 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
4182 C files; there's no need for this, and it forces recompilations
4185 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
4187 * error.c (scm_error): declare scm_error_callback.
4189 * error.h: prototype for scm_error_callback.
4191 * __scm.h: define lgh_error.
4192 (SCM_SYSERROR): redefine using lgh_error.
4194 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
4196 * error.c (scm_error): new procedure.
4198 * error.h: prototype for scm_error.
4200 * Makefile.in (install): install scmconfig.h from the current
4201 directory, not $(srcdir).
4203 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
4205 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
4206 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
4207 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

4213 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
4214 vports.h, weaks.h: #include "libguile/__scm.h", not
4215 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
4216 dependencies are within libguile properly.
4218 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
4220 * Makefile.in (.c.x): Simplify; there's no need to run this rule
4221 when scmconfig.h doesn't exist.
4223 * load.c (scm_sys_try_load): Correct spelling.
4225 * feature.c (scm_loc_features): Make this static.
4227 * Makefile.in (libpath.h): Omit trailing slash from path. We
4228 shouldn't require it of users, so why put it here?
4230 Move code to initialize and search %load-path from ice-9 to C
4231 code, so we can use the load-path to find the ice-9 boot code;
4232 this makes it easier to run Guile without installing it. See
4233 corresponding changes in guile/Makefile.in.
4234 * feature.c: Move stuff concerned with the load path to load.c.
4235 (scm_compiled_library_path): Deleted.
4236 Don't #include libpath.h here.
4237 * feature.h: Don't mention scm_compiled_library_path.
4238 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
4239 <sys/stat.h>, and <unistd.h> (if present).
4240 (R_OK): #define if the system hasn't deigned to.
4241 (scm_loc_load_path): New variable.
4242 (scm_init_load_path, scm_sys_search_load_path,
4243 scm_sys_try_load_path): New functions.
4244 (scm_init_load): Initialize scm_loc_load_path to point to the
4245 value cell of the Scheme %load-path variable.
4246 * load.h: Add declarations for scm_sys_search_load_path,
4247 scm_sys_try_load_path.
4248 * init.c: Call scm_init_load_path.
4249 * Makefile.in (feature.o, load.o): Dependencies updated.
4251 * load.c, load.h: Rewrite using PROTO macro.
4253 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4255 * gc.c (scm_cellp): New function: C predicate to determine if an
4256 SCM value can be regarded as a pointer to a cell on the heap.
4258 * gc.h: Added declaration of scm_cellp.
4260 * gdb_interface.h: New file: The GDB interface header from the GDB
4263 * gdbint.c: New file: GDB interface.
4265 * gdbint.h: New file: GDB interface.
4267 * libguile.h: Added #include <libguile/gdbint.h>.
4269 * init.c (scm_boot_guile): Added scm_init_gdbint.
4271 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
4272 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
4273 found if object files and source are kept separate).
4275 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
4277 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
4279 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
4281 * configure.in: Don't substitute the values of TCL_SRC_DIR and
4282 TK_SRC_DIR; they're not relevant any more.
4284 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
4285 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
4287 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
4289 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
4290 search path, so we can find the <libguile/MUMBLE.h> headers.
4292 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
4294 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
4295 implicit in the .c.o rule.
4296 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
4299 Put the library path in a header file, instead of passing it on
4300 the command line in every compilation.
4301 * Makefile.in (libpath.h): New target.
4302 (feature.o): Depend on libpath.h.
4303 (clean): Delete libpath.h.
4304 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
4305 * feature.c: ... #include "libpath.h" here.
4306 * .cvsignore: Ignore libpath.h.
4308 Don't install the unwashed masses of Guile header files in the
4309 main #include path; put most of them in a subdirectory called
4310 'libguile'. This avoids naming conflicts between Guile header
4311 files and system header files (of which there were a few).
4312 * Makefile.in (pkgincludedir): Deleted.
4313 (innerincludedir): New variable; this and $(includedir) are enough.
4314 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
4315 (installed_h_files): Divide this up. Now this variable lists
4316 those header files which should go into $(includedir) (i.e. appear
4317 directly in the #include path), and ...
4318 (inner_h_files): ... this new variable says which files appear in
4319 a subdirectory, and are referred to as <libguile/mumble.h>.
4320 (h_files): List them both.
4321 (install): Create innerincludedir, not pkgincludedir. Put
4322 the installed_h_files and inner_h_files in their proper places.
4323 (uninstall): Corresponding changes.
4324 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
4325 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
4326 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
4327 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
4328 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
4329 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
4330 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
4331 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
4332 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
4333 vports.h, weaks.h: Find __scm.h in its new location.
4334 * __scm.h: Find scmconfig.h and tags.h in their new locations
4335 (they're both "inner" files).
4337 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
4339 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
4341 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4343 * posix.c: Doc fixes.
4345 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
4347 * socket.c: Don't include a prototype for inet_aton; just use a
4348 K&R style declaration, to avoid warnings but minimize the chance
4349 of conflicts with the system.
4351 On NextStep, <utime.h> doesn't define struct utime, unless we
4352 #define _POSIX_SOURCE before #including it.
4353 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
4354 * acconfig.h: New comment text for above CPP symbol.
4355 * configure.in: Call it.
4356 * posix.c: #define _POSIX_SOURCE if it seems necessary.
4358 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
4360 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
4361 testing for __EMX__.
4363 * posix.c: #include <libc.h>, if it exists.
4365 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
4366 don't even know if the latter exists.
4368 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
4369 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
4370 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
4372 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
4374 (scm_init_posix): Use them when initializing the Scheme constants
4377 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4379 * Makefile.in (libdir, includedir, bindir): Use the
4380 autoconf-supplied values, instead of deriving them ourselves.
4381 (pkgincludedir, datadir, pkgdatadir): New variables.
4382 (install, uninstall): Put the header files in a special
4383 subdirectory, not in the main search path.
4385 * Makefile.in (ALL_CFLAGS): Provide the proper value for
4386 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
4388 * Makefile.in (IMPLPATH): Deleted; never used.
4390 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
4391 on the Tcl/Tk source any more.
4392 (INCLUDE_CFLAGS): Remove references to the above.
4394 * Makefile.in (version.o): Corrected dependencies.
4396 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
4398 * libguile.h: #include "version.h"
4400 * init.c (scm_boot_guile): Call scm_init_version.
4401 * gscm.c (gscm_run_scm): Call scm_init_version.
4403 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
4404 GUILE_VERSION): AC_DEFINE these.
4405 (acconfig.h): #undef the above symbols.
4407 * Makefile.in (libobjs): Add version.o.
4408 (installed_h_files): Add version.h.
4409 (c_files): Add version.c.
4410 (gen_c_files): Add version.x.
4411 (version.o): New rule.
4412 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
4413 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
4414 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
4415 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
4416 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
4417 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
4418 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
4419 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
4420 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
4421 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
4422 weaks.o): Add version.h to dependency lists.
4423 (markers.o): Remove duplicate rule.
4425 * version.h: New file.
4427 * version.c: New file.
4429 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4431 * symbols.c (scm_strhash): scm_downcase is now a function, not an
4432 array; use it appropriately. Since GCC is quite happy to
4433 subscript functions, it never warned us about this; we should use
4434 -Wpointer-arith in the future. I guess we never tested
4437 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
4439 * socket.c: Doc and copyright fixes.
4441 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4443 * debug.c: Fixed and improved gdb support.
4445 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4447 * socket.c: Added declaration of inet_aton to avoid compiler
4448 warning. (Hope this solution is correct.)
4450 * stime.c: Added declaration of ftime. (This is missing in
4453 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
4455 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
4457 * Makefile.in (c_files): add strerror.c.
4459 * strerror.c: new file from Emacs' sysdep.c.
4460 maybe configure should also check for sys_errlist.
4462 * configure.in (AC_REPLACE_FUNCS): add strerror.
4464 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4466 * debug.c (scm_init_debug): Added initialization for
4467 scm_evaluator_traps.
4469 * debug.h, debug.c: Various name changes.
4470 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
4471 "debug-options-interface". See commentary in options.c.
4473 * options.h, options.c: Options now have documentation strings.
4474 Also added a long explanatory commentary.
4476 * eval.c, print.h, print.c, read.h, read.c: Modifications to
4479 * gscm.c, init.c, root.c, throw.c: Bug fixes:
4480 last_debug_info_frame is now updated in all cases.
4482 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
4485 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4487 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
4488 Added option STACK_CHECKING.
4490 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
4492 * Makefile.in: Added {debug,options,srcprop}.{h,c}
4494 * __scm.h: Removed symbols for debugging support.
4496 * acconfig.h: Added symbols for debugging support.
4498 * configure.in: Added user option for debugging support.
4499 --enable-debug will include the debugging code into libguile.a.
4501 * continuations.c (scm_make_cont): Enlarged the #if 0 around
4502 scm_relocate_chunk_to_heap.
4504 * debug.c: New file: low-level debugging support. It also
4505 includes support for debugging with gdb. (The extensions to gdb
4506 are written by Per Bothner at Cygnus.)
4508 * debug.h: New file: low-level debugging support.
4510 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
4511 argument pairs. Extensive modifications to the debugging
4512 evaluator. Added "SECTION:" commentaries to clarify what happens
4513 when, during double compilation. Renamed EVALIMP --> EVALIM.
4514 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
4515 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
4516 the beginning of the file. New procedure: scm_unmemocopy.
4517 Added some global state variables needed by the debugging
4518 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
4519 check_entry, check_apply, check_exit, debug_options and
4520 evaluator_traps. New acro: undefine.
4522 * eval.h: Renamed EVAL --> XEVAL.
4524 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
4525 --> scm_make_weak_key_hash_table.
4527 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
4528 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
4530 * libguile.h: Conditionally include debug.h
4532 * objprop.c (scm_object_properties, scm_set_object_properties_x):
4533 scm_object_properties shouldn't return handle. `handle' now gets
4534 initialized in scm_set_object_properties_x. scm_object_properties
4535 doesn't any longer create an entry in scm_object_whash.
4537 * options.c: New file: handling of run time options.
4539 * options.h: New file: handling of run time options.
4541 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
4543 * print.c: New procedure: scm_print_options
4545 * print.h: Defines for print options.
4547 * read.c: New procedure: scm_read_options
4549 * read.h: Defines for reader options.
4551 * root.h: Added scm_source_whash among scm_sys_protects.
4553 * srcprop.c: New file: source properties.
4555 * srcprop.h: New file: source properties.
4557 * throw.c (jbsmob): Jump buffers are now correctly allocated.
4558 (Bug found by A. Green.)
4560 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
4562 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
4564 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
4566 * libguile.h: #include "objprop.h"; I guess this was forgotten.
4568 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
4569 and should be called by the final client.
4571 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
4573 * gc.h: Use the PROTO macro when declaring functions.
4574 * gc.c: Use the PROTO macro when declaring static functions.
4575 Remove the CPP hair around function definitions.
4577 * gc.c (scm_init_storage): Initialize scm_asyncs.
4579 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
4580 preprocessor symbol; "__scm.h" is where it might get #defined.
4581 * __scm.h: Similar: #include <scmconfig.h> before testing
4584 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
4586 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
4588 * init.c (scm_boot_guile): Add init_func argument; call
4589 (*init_func) instead of calling scm_appinit; it's ucky to
4590 hard-code names for the user's procedures.
4591 * init.h (scm_boot_guile): Adjust declaration.
4593 * __scm.h (PROTO): New macro, for declaring functions with
4596 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
4597 eliminate all the __STDC__ conditionals.
4598 (scm_boot_guile): Add declaration.
4599 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
4600 Remove __STDC__ conditionals around function definitions; the
4601 declarations in init.h will provide the same information, more
4604 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
4605 complain about it in the error message; the error message is
4606 adequate without that note, and there's nothing the user can do
4609 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
4611 * Makefile.in (ancillary): Drop def.sed.
4613 * posix.c (scm_init_posix): Use numeric values, rather than
4614 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
4615 F_OK. The symbols aren't available on some systems, and I'm
4616 pretty sure their values are fixed by common widespread practice.
4617 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
4619 More functions unavailable on some systems.
4620 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
4621 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
4623 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
4624 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
4625 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
4626 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
4627 stub that signals an error as the #else.
4629 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
4631 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
4633 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
4635 * unif.c: include ramap.h.
4637 * read.c (endif): case_insensative_p renamed case_insensitive_p.
4639 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
4641 * ports.c: include sys/ioctl.h.
4643 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
4645 * configure.in: check for sys/ioctl.h.
4647 * ports.c: include <malloc.h> not "malloc.h".
4649 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
4651 * fports.c: remove ttyname and tmpnam declarations.
4653 * posix.c: fewer ttyname declarations.
4655 * fports.c: include <string.h> not "string.h".
4657 * init.c, ioext.c: include string.h and unistd.h.
4659 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
4661 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
4662 genio.c, simpos.c, vports.c: include string.h.
4664 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
4666 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
4668 (scm_addr_buffer_size): change type from scm_sizet to int.
4669 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
4670 from scm_sizet to int.
4672 * error.c: include unistd.h.
4674 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
4677 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
4679 * __scm.hd, def.sed: deleted.
4681 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
4683 Changes for NeXT, suggested by Robert Brown.
4684 * configure.in: Call AC_TYPE_MODE_T.
4685 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
4686 NeXT. Put header file list in alphabetical order.
4687 * configure, scmconfig.h.in: Regenerated.
4688 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
4690 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
4693 * acconfig.h: New file, providing documentation for the CPP
4694 symbols defined in configure.in
4695 * acconfig-1.5.h: Removed; superceded by the above.
4697 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
4699 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
4701 * fports.c (scm_open_file): don't return #f, throw error.
4703 * ioext.c (fileno): renamed from %fileno.
4704 (soft-fileno): deleted.
4706 * ports.c (scm_port_revealed): don't need to check for -1 from
4708 (scm_set_port_revealed_x): return unspecified, not #f.
4710 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
4712 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
4714 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
4716 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
4718 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4720 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
4721 This is necessary on Ultrix, and doesn't hurt portability.
4723 * Makefile.in (dist-dir): New target, implementing a new dist system.
4724 (installed_h_files): Put in alphabetical order.
4725 Remove duplicate entries for markers.h and unif.h.
4726 (c_files): Remove duplicate entries for markers.c.
4727 (ancillary): Renamed from anillery; all uses changed. Remove
4728 PLUGIN; it's a directory, and needs special treatment in dist-dir.
4729 Remove all the ../doc/* files; doc/Makefile.in handles that.
4731 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
4733 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
4734 every if must have an else, or else the whole command has a
4735 non-zero exit code whenever the if's condition is false.
4737 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
4739 * posix.c: include string.h.
4741 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4743 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
4746 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
4747 Remove leading % from scheme names.
4748 Do not return error values, call SCM_SYSERROR or similar.
4750 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
4752 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
4754 * struct.c (scm_init_struct): new file.
4756 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
4758 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
4759 (scm_list_head): added list-head for rapidly chopping argument
4760 lists off of longer lists (and similar).
4762 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
4764 * objprop.c (scm_object_property): assq the cdr of the whash
4765 handle for obj, not the handle itself.
4767 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
4769 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
4770 weak hash tables last of all marking to avoid an obscure gc bug.
4771 WARNING: circular lists stored in a weak hash table will hose us.

4994 initialization to fix a race condition.
4996 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
