3 * list.c (scm_list_append_x): Allow non-pair as last argument.
4 This is consistent with the R4RS append and is probably the
5 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
7 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
9 * stime.h: prototype for scm_times.

26 (scm_fcntl): the first argument can now be a file descriptor. The
27 third argument is now optional.
29 * posix.c (scm_execl, scm_execlp): make the filename argument

40 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
41 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
42 argument to SCM_ASSERT. Furthermore, the name of the function
43 should be passed as first argument when signalling
44 SCM_WNA. (Thanks to Thomas Morgan)
46 * gsubr.c (scm_gsubr_apply): From Radey Shouman
47 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
48 dispatches on the number of actual args has a default case
49 reporting an internal error. This is a vestige from a version
50 that mallocated a SCM vector to hold the arguments. In the
51 current version this check is too late: if it ever happens we will
52 have already overstepped the bounds of the array.
54 Also, the patch [...] adds a check for too many actual arguments."
56 mdj: Removed check for "internal programming error".

75 fold in the functionality of scm_primitive_dup.
76 (scm_primitive_dup): deleted.

80 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
81 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or

204 the dynamic object data below the linking of the object to avoid
205 memory leak when the linking code throws an error. Now the code
206 leaks a whole dynamically linked library when must_malloc throws,
207 but that should be much less likely.
209 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>

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

281 have to do this explicitly. Also, if regexp/basic is supplied, then
282 turn off REG_EXTENDED.
283 (scm_init_regex_posix): New regexp/basic symbol.
284 (REG_BASIC): #define this if it is not already present.

307 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
309 (scm_init_regex_posix): Define constants for the REG_mumble flags;

327 * root.c: Establish a reliable catch-all handler for the new root.

343 across this. Only works on GCC. Otherwise, we hope for the best.
344 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
345 the feeling that real thread systems will not need this...

374 * ioext.c (scm_duplicate_port): bug fix: don't try to make the

379 * ports.h: new prototype.
380 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
382 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>

385 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.

391 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA

396 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
397 top of the word, it should be unsigned.
399 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
400 is defined, to avoid warnings; it's only used in the
401 conflict-checking code. Which might go away anyway.
402 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
403 conditionals; put the label definition in an #if too, to stifle
406 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and

458 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
460 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
461 23:47:01 1997" changelog: Slots are now initialized with `#f' by
462 default and not `()'. `#f' is the canonical non-value in Scheme,
465 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
467 * struct.c (struct_printer): New variable that holds a handle on
468 the Scheme variable *struct-printer*. This variable can be set by
469 Scheme code to override the printing of structures.
470 (scm_print_struct): If struct_printer is set, call it. If it is
471 not set, or returns #f, print the structure in the old fashion.
472 Include "eval.h" for scm_apply.
474 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
476 * struct.c (scm_struct_ref, scm_struct_set_x): Use

478 -scm_struct_n_extra_words.
480 On the route to fancier struct printing:
481 * struct.c (scm_print_struct): New function to print a structure.
482 Include "genio.h" to support it. This function doesn't do
483 anything interesting right now, but I think it should be here
485 * struct.h: Include "print.h" and add prototype for
487 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
488 print structures ourself.

495 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
497 * scmsigs.h, async.h: updated.
499 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
502 * posix.c (scm_uname): interpret only negative values as an error.
503 Solaris normally returns a positive value.
505 * script.c (scm_compile_shell_switches): if we are not going into
506 an interactive repl, set scm_mask_ints to zero so that asyncs can
509 * simpos.c (scm_system): don't ignore/unignore signals around
512 * posix.c (scm_open_pipe): don't ignore/unignore signals around
515 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
516 done in boot-9.scm instead.
518 * scmsigs.c, async.c: Major rewriting of signal handling code.
519 (scm_sigaction): new procedure.
520 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
522 (scm_raise): return unspecified, throw error on failure.
524 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
526 * regex-posix.c (scm_init_regex_posix): Register the "regex"
527 feature, to help boot-9.scm decide whether to import the regex
530 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
532 * eval.c: Include scmconfig.h at the beginning of the file so that
533 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
536 * regex-posix.c: #include "_scm.h" before conditionally #including
537 <regex.h>; the former defines HAVE_REGCOMP.
539 * regex-posix.c: #include <regex.h> conditionally, so the file is
540 CPP'able (for dependency scanning) even on systems that don't have
543 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
545 Add new R4RS-compliant syntax for keywords.
546 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
547 regardless of the setting of the `keywords' read option.
548 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
549 can be re-read no matter what the setting of the `keywords' read
552 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
554 Add support for POSIX regular expressions.
556 * regex-posix.c, regex-posix.h: New files. (Some code
557 is taken liberally from rx/rgx.c in the old Guile dist.)
559 * init.c: Include regex-posix.h.
560 (scm_boot_guile_1): Call scm_init_regex_posix.
562 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
563 Add regex-posix.[ch] sources.
564 * Makefile.in: Regenerated.
566 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
567 to do this automatically? It didn't for me, bleh.)
569 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
571 * fports.c (print_pipe_port): New function.
572 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
573 latter doesn't even take the right arguments.
575 * Makefile.am: Increment shared lib revision number. I think
576 sometimes the uninstalled Guile finds the installed shared lib;
577 Gord says doing this might help. As things turned out, I can't
579 * Makefile.in: Regenerated.
581 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
582 passing it as the closure argument to scm_boot_guile. (Bill
585 * ports.c (print_void_port, putc_void_port, puts_void_port,
586 write_void_port, flush_void_port, getc_void_port, close_void_port,
587 noop0): Use ANSI prototypes instead of K&R declarations, so the
588 initialization of void_port_ptob gets aggressively type-checked.
589 Fix arguments of print_void_port and write_void_port. (Bill

623 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
625 * script.c (scm_find_executable): Use prototype-style definition
626 here; apparently it's not quite right to have const in a prototype
627 and then use a K&R declaration. I wonder if stuff like this will
628 go away if we compile with -Wrequire-prototypes, or whatever that
629 is... (Bernard URBAN)
631 * scmhob.h: New text from Bernard URBAN.
633 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
635 * script.c: Don't #define const on hpux. Configure takes care of
636 this. (Thanks to Larry Schwimmer.)
638 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
639 decide whether to #include <unistd.h>, instead of listing a bunch
640 of systems. Don't #include stdio twice. Removed dyked-out
641 definition of scm_find_impl_file.
643 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
645 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
646 library version info to 1:0.
647 * Makefile.in: Regenerated.

653 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
654 throw.c: Update copyright years; these files have been worked on
655 significantly in 1997, but only had copyright years for 1996.
656 Also, change name of copyright holder on some from Mikael
657 Djurfeldt to Free Software Foundation; he has signed papers
658 assigning the changes to the FSF.
660 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
661 reason not to give the user the option.
663 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
664 Return #f on end-of-file when scanning table (i.e. when called
665 with no arguments). Try to catch errors, when we can.
666 * posix.c (scm_getgrgid, scm_getpwuid): Same.
668 * script.h (scm_shell_usage, scm_compile_shell_switches): New
669 external declarations. These are useful.
671 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
673 * posix.c: don't include <sys/select.h> or define macros for
674 select, since they were not used in this file.
676 * filesys.c (scm_select): make the fifth parameter microseconds,
677 not milliseconds. let the fourth parameter be either a real value
678 or an integer or #f. The first, second and third arguments can
679 now be vectors: the type of the corresponding return set will be
681 (set_element, get_element): new static procedures.
683 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
685 * strports.c (scm_eval_string): New function.
686 (scm_eval_0str): Trivially re-implemented in terms of
688 * strports.h (scm_eval_string): New extern decl.
690 * net_db.c (h_errno): Add extern decl for this.
692 * fports.c (local_pclose): New function.
693 (scm_pipob): Use it in the initializer here.
696 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
697 Use a meaningful error message when signalling an error. For
698 this, scm_gethost must check h_errno rather than errno.
700 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
702 * Makefile.in: Regenerated, using automake-1.1p.
704 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
706 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
709 * script.c (scm_compile_shell_switches): don't append (quit) if
711 (scm_shell): call scm_exit_status and exit on the result of the
714 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
716 Ensure that shared substrings are handled properly when passed to
717 a system call or other foreign function. Many thanks to Tim
719 * symbols.h (SCM_COERCE_SUBSTR): new macro.
720 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
721 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
722 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

724 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
725 (scm_display_error_message): use RO macros when strings may be RO.
726 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
727 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
728 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

732 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
733 scm_strftime), vports.c (scm_make_soft_port): use
734 SCM_COERCE_SUBSTR to make sure shared substrings are
737 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
739 * error.c (scm_error): Add newline to error message.
741 * init.c (scm_init_standard_ports): Doc fix.
743 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
745 * dynl-shl.c: Completely replaced with new code from Bernard
748 * script.c (scm_ice_9_already_loaded): New variable.
749 (scm_compile_shell_switches): Use it.
751 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
753 * filesys.c (scm_input_waiting_p): add missing third argument to
756 * stime.c (scm_localtime): copy the result of localtime before
757 calling gmtime in case they share a buffer.
758 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
761 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
763 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
765 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
767 * Makefile.am (check-local): New target, which causes 'make check'
768 to run gh_test_c and gh_test_repl, with some trivial input.
769 * Makefile.in: Rgnrtd.
771 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
773 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
776 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
778 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
779 sure how this was supposed to work.
780 (scm_async_click): don't send SCM_TICK_SIGNAL.
781 (scm_init_async): don't initialize %tick-thunk.
783 * the following change doesn't affect the Scheme interface:
784 gc-thunk is called at the end of garbage collection. however it's
785 no longer implemented by pretending it's a signal.
787 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
788 system async corresponding to scm_gc_thunk.
789 * async.h: declare scm_gc_async.
790 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
791 gc-thunk directly, instead of going through a signal handler.
792 (scm_gc_async): new variable, points to the GC system-async.
793 (scm_init_async): save the GC async as scm_gc_async instead
794 of using system_signal_asyncs.
795 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
797 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
799 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
800 Don't screw up if we're interrupted.
801 * Makefile.in: Regeneradet.
803 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
805 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
807 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
808 we're not using AM_INIT_GUILE_MODULE any more.
809 * Makefile.in: Reneregated.
811 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
813 Functions for finding variable bindings, grace à Tim Pierce.
814 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
815 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
817 Get 'make dist' to work again.
818 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
819 * Makefile.in: Regenerated, like a surry without a fringe on top.
821 Changes for reduced Guile distribution: one configure script,
823 * configure.in, configure: Removed.
824 * acconfig.h, acinclude.m4: Moved to parent directory, where the
825 real configure script lives.
826 * Makefile.in, scmconfig.h.in: Regenerated.
828 * init.c: #include "script.h", to get prototype for script.c's
831 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
833 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
834 scm_must_malloc, not raw malloc.
836 * script.c (scm_compile_shell_switches): Dyke out debugging output
839 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
841 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
843 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
844 system has them. Hope this is safe. Previously
845 sys/timeb.h was included if HAVE_FTIME was defined or if
846 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
847 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
849 * ioext.c (scm_setfileno): add missing third argument to
852 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
854 * eq.c (scm_equal_p): Correctly compare strings of different
855 varieties. (Thanks to Tim Pierce.)
857 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
859 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
860 #! block comment must occur on a line all by itself.
862 Move most of the guts of shell command processing into libguile,
863 so guile.c can be very small (and eventuallly auto-generated. (I
864 mean, generated mechanically, not self-generated. Hmm.))
865 * guile.c, script.c, script.h: New source files.
866 * init.c (scm_boot_guile_1): Call scm_init_script.
867 * libguile.h: #include "script.h".
868 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
869 targets, for new executable.
870 (libguile_la_SOURCES): Mention script.c.
871 (modinclude_HEADERS): Add script.h.
872 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
873 not dynamic linking is enabled. This is because we're generating
874 executables now. Move CY_AC_WITH_THREADS call after those, so the
875 values of cy_cv_threads_libs captures the libs chosen above.
876 * Makefile.in, configure, aclocal.m4: Regenerated.
878 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
879 We don't maintain this interface any more, and it just confuses
882 * alloca.c: #include <scmconfig.h>, not <config.h>.
883 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
884 it'll get included in disties.
886 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
888 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
889 be distributed, because they confuse people.
890 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
892 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
894 * configure.in: check for presence of gethostent (not present on
896 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
897 * configure, scmconfig.h.in: Regenerated.
899 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
901 * backtrace.c (scm_backtrace): Split message string across
902 newlines properly. GCC is more tolerant of this than other
905 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
907 Merge threads directory into libguile.
908 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
909 threads.h: New source files.
910 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
911 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
913 (modinclude_HEADERS): Add threads.h, coop-defs.h.
914 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
915 coop-threads.c.cygnus, coop-threads.h.cygnus.
916 * configure.in: If we're using threads, include threads.o in
918 * _scm.h, libguile.h: threads.h lives in this directory now.
919 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
920 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
921 currently used, but brought along for information's sake.
922 * ChangeLog-threads: log from old 'threads' directory.
923 * Makefile.in, configure: Rebuilt.
925 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
927 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
930 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
932 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
934 Merge GH interface library into libguile.
935 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
936 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
937 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
938 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
940 (EXTRA_libguile_la_SOURCES): ... here.
941 (pkginclude_HEADERS): Add variable, to get gh.h installed.
942 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
943 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
944 New variables, describing how to build the gh test programs.
945 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
946 build the test programs, and we probably should have been linking
947 libguile.la against them all along, to support AIX shared libs.
948 Add cflags for threads to CFLAGS; add libs for threads to new
949 variable THREAD_LIBS, used in Makefile.am.
950 * ChangeLog-gh: log from old `gh' subdirectory.
951 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
953 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
955 * acconfig.h: Undo change of Apr 9; including the definition of
956 PACKAGE in the guile headers conflicts with applications' own
958 * scmconfig.h.in: Regenerated.

969 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
971 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
972 have S_IFSOCK. This is the case under Ultrix.
974 * posix.c (scm_status_exit_val, scm_status_exit_val,
975 scm_status_term_sig, scm_status_stop_sig): Modified to work with
976 Ultrix versions of WIFSTOPPED, etc., which assume that their
977 arguments are lvalues (hmm).
979 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
983 * throw.c: Doc fixes; rearranged.
985 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
987 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
989 * acconfig.h: Added entry for PACKAGE.
990 * scmconfig.h.in: Regenerated.
992 Changes to work with automake-1.1n, which has better libtool support.
993 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
994 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
996 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
998 * Makefile.in: Rebuild.
1000 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1002 * stime.c (scm_mktime): take an optional zone argument.
1003 (scm_localtime): check putenv return value.

1007 (bdtime2c, setzone, restorezone): new static procedures.
1008 (scm_mktime, scm_strftime): use them.
1009 (scm_strftime): don't call mktime before strftime. Use
1010 filltime for return value.
1011 (filltime): convert NULL zname to #f.
1012 (scm_strptime): return a count of characters consumed, not
1013 the remaining string.
1015 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1017 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.

1020 Uncomment localtime and mktime.
1022 * configure.in: add AC_STRUCT_TIMEZONE.

1026 * stime.c (scm_init_stime): don't define ticks/sec.
1027 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
1028 return value problem and is still portable.)
1030 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
1032 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
1033 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
1034 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
1035 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
1036 cpp_err_symbols.c): Corresponding changes.
1037 * Makefile.in: Regenerated.
1039 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
1041 * posix.c (scm_putenv): don't check HAVE_PUTENV.
1042 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
1043 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
1044 * putenv.c: new file, from sh-utils 1.12.
1046 * posix.c (scm_environ): use malloc in place of scm_must_malloc
1047 since allocation isn't for Scheme objects.
1048 (scm_putenv): copy strings before placing in the environment.
1050 * stime.c (scm_current_time): throw an error if time returns -1,
1051 instead of returning #f.
1052 (scm_get_internal_real_time, scm_get_internal_real_time): use
1053 scm_long2num for return value instead of SCM_MAKINUM.
1055 * stime.h: prototypes updated.
1057 * stime.c (scm_time_in_msec): apparently unused, deleted.
1059 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
1061 * configure.in: check for gettimeofday.
1063 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
1064 which may be more usefully portable than a gettimeofday interface.
1066 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
1068 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
1070 * Makefile.in: Regenerated.
1072 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
1074 * stime.c (filltime): recovered static procedure.
1075 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
1078 * posix.h: add prototype for scm_close_pipe, remove prototypes for
1079 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
1081 * posix.c (scm_mknod): split the mode argument into type and perms
1082 arguments, like the extra fields returned by stat.
1084 * fports.c (scm_pipob): set the close, free and print procedures.
1085 (scm_close_pipe): new procedure.
1087 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
1088 define them in boot-9.scm
1090 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1092 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
1093 wan't defined. Don't include fd.h.
1095 * Previously fd.h was regenerated whenever configure was run,
1096 forcing a couple of files to be recompiled.
1098 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
1099 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
1100 Check for _fileno as well as _file.
1102 * ioext.c: don't fd.h.
1103 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
1106 * Change the stratigy for getting information about errno
1107 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
1108 generating lists of symbols during the build process, which will
1109 not always work, include comprehensive lists in the distribution.
1110 To help keep the lists up to date, the "check_signals" and
1111 "check_errnos" make targets can be used.
1113 * configure.in: don't check for a command to extract errno codes.
1114 * Makefile.am: update file lists, remove errnos.list and errnos.c
1115 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
1116 check_errnos targets.
1117 (CLEANFILES): remove errnos.c and errnos.list, add
1118 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new

1124 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
1125 * error.c (scm_init_error): #include cpp_err_symbols instead of
1127 * posix.c (scm_init_posix): don't intern signal symbols. #include
1130 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
1132 * strop.c (scm_i_index): allow the lower bound to be equal to the
1133 length of the string, so a null string doesn't always give an error.
1135 * posix.h: new prototypes.
1136 * posix.c (scm_status_exit_val, scm_status_term_sig,
1137 scm_status_stop_sig): new functions, as in scsh. They break down
1138 process status values as returned by waitpid.
1140 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
1142 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
1143 configure doesn't know about it.
1145 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1147 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
1149 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
1150 which defines C variables with global linkage.
1152 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1154 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
1157 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
1159 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
1160 has time to check why this doesn't work well with continuations.
1162 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
1164 * Fix shell syntax error; some shells won't tolerate
1165 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
1167 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
1169 * posix.c (scm_uname): throw an error if uname fails instead
1172 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
1174 * error.c (err_head, scm_errno, scm_perror): obsolete procedures

1179 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1181 * acconfig.h: Removed PACKAGE.
1183 * scmconfig.h.in: Regenerated.
1185 * snarf.h: g++ says it's non-portable not to specify the first
1186 argument in a varargs declaration. I introduced the first
1187 argument by using preprocessor conditionals.
1189 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
1191 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
1192 (scm_freopen): use RO string macros for filename and modes.
1193 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
1195 * posix.c (scm_getgrgid): simplify conversion of name to C string.
1196 (scm_mknod): use RO string macros for path.
1198 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
1199 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
1201 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
1202 use SCM_ROSTRINGP and SCM_ROCHARS.
1204 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1206 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
1209 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
1210 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
1211 support for byte vectors.
1213 * print.c (scm_iprin1): Limit number of vector elements printed
1214 according to pstate->length.
1216 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
1218 * backtrace.c (scm_display_error_message): don't segv if message
1221 * error.h: prototype for scm_error_scm.
1223 * error.c (scm_error_scm): new procedure, reimplements scm-error
1224 in C and uses scm_error.
1226 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
1228 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
1229 pointer to the Scheme variable read-hash-procedures and intern it
1230 in scm_init_read. Modify scm_read_hash_extend and
1231 scm_get_hash_procedure to use the pointer.
1233 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1235 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
1236 (SCM_KEYWORD_STYLE): defined.
1238 * read.c (scm_read_opts): add a keywords option. This isn't a
1239 boolean option, in case someone wants to add support for DSSSL
1241 Setup scm_keyword_prefix symbol.
1242 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
1244 I've left keyword support disabled by default, since it doesn't
1245 seem to break the module system and it gives R4RS standard behaviour.
1246 It can be reactivated with (read-set! keywords 'prefix).
1248 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1250 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
1251 before constructing arbiter.
1253 * eval.c (scm_m_define): Bugfix: Check that the object is a
1254 closure before setting the procedure property!
1256 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
1258 * ports.c: Removed `ungetc-char-ready?'.
1260 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
1262 * read.c (scm_init_read): intitialise scm_read_hash_procedures
1263 (idea from Mikael: make it a pair so scm_permanent object only
1265 (scm_read_hash_extend): don't call scm_permanent_object.
1266 (ideas from Mikael): if chr is already in the list, replace its
1267 procedure instead of appending it again. If proc is #f, remove
1269 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
1271 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
1273 * gdbint.c (gdb_read): update scm_lreadr usage.
1275 * load.h: update prototypes.
1277 * load.c (scm_primitive_load, scm_read_and_eval_x,
1278 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
1280 * read.h: add prototype for scm_read_hash_extend. Change args for
1283 * read.c (scm_read_hash_procedures): new variable.
1284 (scm_read_hash_extend): new procedure.
1285 (scm_get_hash_procedure): new procedure.
1286 (scm_lreadr): use scm_get_hash_procedure instead of an argument
1287 for extended # processing.
1288 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
1289 scm_read_token): remove case_i, sharp arguments. Change callers.
1291 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
1293 * read.h (SCM_N_READ_OPTIONS): increase to 3.
1294 (SCM_CASE_INSENSITIVE_P): define.
1296 * read.c: add case-insensitive option to scm_read_opts.
1297 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
1298 to determine whether to convert symbol case.
1299 (default_case_i): definition removed.
1300 * read.c (scm_read_token): if case_i, downcase ic before doing
1303 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1305 * configure.in: Added configuration option `guile-debug'.
1306 Configure with --enable-guile-debug if you want a bunch of extra
1307 functions used for debugging when developing Guile.
1309 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
1311 * procs.c (make-cclo): New undocumented debugging procedure: Make
1312 compiled closure with internal procedure PROC and length LENGTH.
1313 Only compiled if GUILE_DEBUG is defined.
1315 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
1317 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
1319 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
1321 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
1322 with 3 or more args internally to the evaluator.
1324 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1326 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
1327 with 3 or more args internally to the evaluator. This is mainly
1328 because we don't want to pass entry and exit points of the
1329 debug support twice, but it also seems to increase the speed of
1330 the evaluator for such calls (e. g. (+ 1 2 3)).
1332 * backtrace.c (scm_display_application): New procedure:
1333 display-application; Set fancy printing parameters individually
1334 for different types of display (backtrace, error, application).
1335 (These should of course be customizable!)
1337 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
1338 clear the CHECK-flags.
1340 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1342 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
1344 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1346 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
1347 from pairs with a GLOC in the car.
1349 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
1350 otherwise `symbol-hash' will behave badly.
1351 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
1352 we get segmentation fault!
1354 * symbols.c: Added #include "weaks.h". New functions:
1355 `builtin-bindings' and `builtin-weak-bindings'. (These will be
1356 moved to an extraneous library when we split libguile.)
1358 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1360 * filesys.c (scm_stat): stat now takes fport arguments too as
1361 documented in the manual.
1363 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1365 * debug.c (scm_single_step): Bugfix: Call continuation with
1366 scm_call_continuation instead of throwing to it.
1368 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1370 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
1371 argument wasn't declared to be optional.
1373 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1375 * stime.c (scm_init_stime): Add feature "current-time".
1377 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
1379 * throw.h: prototype for scm_exit_status.
1380 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
1381 args to derive an exit status. Allows (quit) to work from a
1383 (scm_exit_status): new function.
1386 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1388 * eval.c (scm_deval): Removed some old code.
1389 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
1391 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
1394 * symbols.c (msymbolize): Bugfix: Must initialize property list to
1397 * procs.c: Introduce the existent C function scm_thunk_p at the
1398 Scheme level as well.
1400 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1402 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
1403 used from C to easily lookup the value of a symbol in the current
1406 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1408 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
1409 scm_init_unif in this file. This will also fix a previous problem
1412 * configure.in: Added AM_MAINTAINER_MODE
1414 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1416 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
1419 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1421 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
1422 source files that are not always included in libguile but should
1423 have their dependencies calculated by automake. This variable is
1424 recognized by automake, no further magic is needed.
1425 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
1426 to deal exclusively with *.lo files, as it seems. The *.o files
1427 are built automatically when the corresponding *.lo file gets
1430 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
1432 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
1435 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
1437 * unif.c (scm_array_set_x): minor change to argument error checking.
1439 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
1441 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
1442 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
1443 They should only be included in the library at configure.in's
1445 (libguile_la_LDADD): Include the appropriate .lo files here.
1446 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
1447 so we know when to build them (and their .lo bretheren).
1448 * configure.in (LIBLOBJS): New substituted variable. We let
1449 configure decide which .o files to include in LIBOBJS, and then
1450 put the corresponding list of .lo files in LIBLOBJS. The latter
1451 is what we pass to libtool.
1452 * Makefile.in, configure: regenerated.
1454 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
1456 * symbols.c (scm_sysintern0): New function. Contains the core of
1457 old scm_sysintern but doesn't take a second value argument.
1458 (scm_sysintern): Now uses scm_sysintern0.
1459 (scm_sysintern_no_module_lookup): Renamed to
1460 scm_sysintern0_no_module_lookup and doesn't take a second value
1461 argument any longer.
1463 * symbols.h (scm_sysintern0: Added declaration.
1465 * options.c (scm_init_opts): Use scm_sysintern0 instead of
1466 scm_sysintern when interning option keys. Otherwise we risk
1467 destroying the values of already interned variables.
1469 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
1470 scheme-level boolean (use SCM_NFALSEP).
1472 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
1474 (scm_backtrace): New function. (C version of old function from
1475 boot-9.scm) Motivation: Make it possible to display backtraces
1476 without depending on boot-9.scm. (I'm uncertain if this
1477 motivation is good enough...)
1479 * root.h (scm_root_state): Add member the_last_stack_var.
1480 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
1482 * root.c (mark_root): Mark scm_the_last_stack_var.
1484 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
1487 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
1489 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
1490 1. mark_lazy_catch didn't mark the smob.
1491 2. Both functions above have standard variants:
1492 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
1493 free_lazy_catch --> scm_free0.
1495 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
1497 * throw.c (scm_internal_lazy_catch): New function.
1498 (scm_lazy_catch): Rewritten to use it.
1499 (scm_ithrow): Handle the new lazy catch representation.
1500 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
1501 that doesn't have a jmpbuf is a lazy catch clause.
1502 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
1503 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
1504 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
1506 (scm_init_throw): Register the new lazy-catch smob type.
1507 * throw.h (scm_internal_lazy_catch): decl for new function.
1509 * throw.c (scm_internal_catch): Doc fixes.
1511 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
1512 configure.in. Including this might cause problems if applications
1513 that link against libguile include their own copies of alloca, but
1514 if they're using autoconf, they should be adding libguile to LIBS
1515 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
1516 the copy in libguile, and things will be okay. (I think.)
1518 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1520 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
1522 strop.h: move prototypes too.
1524 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
1526 * posix.c (scm_init_posix): don't intern EINTR since it's now done
1529 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
1530 etc. I deleted them from filesys.c long ago, but didn't
1531 notice they were here too (although ineffective since
1532 sys/stat.h wasn't included).
1534 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
1536 * eval.c: Don't define alloca in GCC case. gcc will automatically
1537 use __builtin_alloca if appropriate.
1539 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
1541 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
1542 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
1543 that values of automatic variables are preserved. See comments
1544 for safe_setjmp for details.
1546 Change from Thomas Morgan:
1547 * variable.c: Include eq.h.
1548 (var_equal): New function.
1549 (variable_smob): Use var_equal as the discriminator for variables.
1551 * throw.c (s_throw): Remove extraneous declaration.
1553 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
1554 * eval.c: Add necessary CPP cruft to support that.
1555 * configure, Makefile.in, scmconfig.h.in: regenerated.
1557 Change from Thomas Morgan:
1558 * procprop.c (scm_procedure_properties): Convert the Scheme
1559 boolean returned by scm_procedure_p into a C boolean before using
1560 it as a condition for SCM_ASSERT.
1561 (scm_procedure_property): Likewise.
1563 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
1564 indications of Unixness.
1567 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
1569 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
1571 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
1573 * read.c (scm_lreadr): use scm_misc_error to improve one of the
1574 "unknown # object" error messages.
1576 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
1577 (scm_i_index) and declare it static. Add a 'direction' argument
1578 to indicate what way the search should go.
1579 (scm_i_index): throw out-of-range error instead of wrong-type-arg
1581 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
1582 strop.h: remove scm_i_index, scm_i_rindex prototypes.
1584 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1586 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
1588 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
1589 to avoid clash with various scsh forks.
1591 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
1593 The following two changes (ramap.c, throw.c) are motivated by the
1594 apparent unportability of forward declarations of static arrays of
1595 the form `static foo bar[];'.
1597 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
1598 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
1600 * throw.c (scm_throw): Moved above scm_ithrow.
1602 * options.h: Removed the extern declarations of scm_yes_sym and
1603 scm_no_sym since these are static.
1605 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1607 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
1609 * Makefile.am: remove AWK=@AWK@.
1610 Add a rule for generating errnos.list.
1611 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
1613 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
1614 don't extract errnos, just set a variable (avoids the
1615 need to recompile error.c just because configure is run.)
1617 * unif.h: update prototypes.
1618 * unif.c (scm_uniform_array_read,write): change the offset and
1619 length arguments to start and end, for consistency.
1621 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
1623 * ioext.h: update prototypes.
1624 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
1625 scm_read_line_x, it's a more general procedure using an
1626 interface from scsh. read-line and read-line! are now defined
1628 Note that the new read-line trims the terminator
1629 by default, previously it was appended to the returned string. An
1630 optional argument specifies how to process the terminator (scsh
1631 compatible). For the old behaviour: (read-line port 'concat).
1632 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
1633 returns a pair, but is converted to multiple values if the scsh
1636 socket.h: update prototypes.
1637 * socket.c (scm_recvfrom): for consistency with other procedures,
1638 take start and end as separate optional arguments.
1639 (scm_recv, scm_recvfrom): don't allow the second argument
1640 to be a size, only a buffer. Change the scheme names to
1641 recv! and recvfrom!. Don't return the buffer.
1643 * ioext.h, posix.h: move prototypes too.
1644 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
1645 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
1646 "read.h" and "unif.h".
1647 * ioext.c: include "chars.h"
1649 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
1651 * dynl.c: The dynamic linking and module registration functions
1652 are now defined even when dynamic linking is not available for the
1653 host system. Some of their functionality can be done without
1654 dynamic linking; when it's really needed, they throw errors.
1656 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
1658 * configure.in: Only define DYNAMIC_LINKING when one of the system
1659 dependent functions is detected.
1660 * dynl.c (scm_dynamic_func): New function to get the address of a
1661 function in a dynamic object.
1662 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
1663 produced by scm_dynamic_func as the thing to call.
1665 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
1667 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
1668 (scm_register_module_xxx, scm_registered_modules,
1669 scm_clear_registered_modules): New functions.
1671 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
1673 * symbols.c (scm_sysintern): Renamed to
1674 scm_sysintern_no_module_lookup.
1675 (scm_sysintern): New function to take the place of the old
1676 scm_sysintern. It uses the current toplevel lookup closure to give
1677 the symbol its value. This is a temporary hack to put packages
1678 like gtcltk into their own module.
1679 (scm_can_use_top_level_lookup_closure_var): New variable to tell
1680 us whether `scm_top_level_lookup_closure_var' has been initialized
1682 * eval.c (scm_init_eval): Set it.
1684 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
1686 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
1687 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
1689 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
1691 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
1692 scm_sys_dup): deleted: FD capability will be added to other
1694 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
1695 scm_fd_free, fd_smob, scm_intern_fd.
1696 (scm_open): renamed from scm_sys_open. Return a port instead of
1697 an FD object. Make the mode argument optional.
1698 (scm_sys_create): deleted, it's just a special case of open.
1699 (scm_init_filesys): move interning of constants O_CREAT etc.,
1700 here (were previously using SCM_CONST_LONG macro).
1701 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
1703 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
1704 include "fports.h" and <stdio.h>
1705 (scm_stat, scm_select): don't support FD objects.
1707 * error.h: adjust scm_syserror_msg prototype.
1708 * error.c (scm_syserror_msg): take an extra argument for errno.
1709 Using the global value didn't always work, since it could be
1710 reset by procedure calls in the message or args arguments.
1712 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
1713 I don't understand why the check was there (and what about the
1716 * strop.c (scm_string_copy): allow shared substrings to be copied.
1718 * unif.h: corresponding change to prototypes.
1719 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
1720 recognize two new optional arguments: offset and length. Allow
1721 the port argument to be an integer (file descriptor, for scsh).
1722 Include <unistd.h> for "read" prototype.
1724 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
1726 * socket.c: don't include filesys.h.
1728 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
1730 * Makefile.am: add AWK=@AWK@ (?)
1732 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
1734 Add a rule to generate errnos.c from errnos.
1735 * error.c (scm_init_error): include errnos.c.
1736 * errnos_cnvt.awk: new file, converts the list of errno codes to
1738 * errnos_get.c: new file.
1739 * errnos.default: new file, contains errnos to try if they can't
1740 be extracted from errno.h.
1741 * configure.in: if using GCC, try and extract errno codes from
1745 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
1747 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
1748 * Makefile.am: Made libguile into a libtool library.
1749 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
1750 Set libtool_libs to indicate that libguile is a libtool library.
1751 See guile/ChangeLog for details.
1752 * .cvsignore: ignore "*.lo", the libtool library objects.
1754 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1756 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
1757 use htons in getservbyport argument.
1759 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
1761 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
1762 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
1765 * objprop.c (scm_object_property): No need to take the CDR of the
1766 value returned by scm_object_properties, since Aug 20 change.
1768 * configure.in: When checking for struct linger, #include
1769 <sys/types.h> as well as <sys/socket.h>. I've never known
1770 <sys/types.h> to cause any portability problems, and Solaris's
1771 <sys/socket.h> needs it.
1772 * configure: Rebuilt.
1774 I think the Sun compiler has chosen a perverse way to interpret
1775 ANSI declarations combined with K&R definitions. We'll
1776 appease it a little bit. But when it invades France, we fight.
1777 * print.c (scm_iprlist): Change 'tlr' argument to an int.
1778 * print.h (scm_iprlist): Here too.
1779 * numbers.c (scm_divbigdig): Change definition to match
1780 declaration in numbers.h.
1781 * unif.c (scm_makflo): Change definition to match declaration in
1784 * init.c (scm_boot_guile): Don't return the value of
1785 scm_boot_guile_1. This function doesn't return a value;
1786 scm_boot_guile_1 doesn't return a value (or return at all).
1788 * eval.c (unmemocopy): Add a semicolon to appease the Sun
1791 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
1792 compile. I have a feeling this function is a bad idea anyway ---
1793 one should always test for features, not systems.
1795 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
1796 semicolons. Only pure luck kept this from being noticed earlier.
1798 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
1800 * socket.c (scm_recvfrom): Added missing semicolon.
1802 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1804 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
1805 the buffer and start and end positions for scsh networking
1808 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
1810 * configure.in: Revert previous change to this file; the problem
1811 is due to transient automake weirdness.
1812 * configure: Rebuilt.
1814 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
1815 PLUGIN/guile.libs. configure generates the latter from the former.
1816 * Makefile.in: Rebuilt.
1818 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
1819 need this if we install scripts, like guile-snarf.
1820 * configure: Rebuilt.
1822 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1824 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
1826 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
1828 * socket.c (scm_addr_vector): fix faulty scm_listify.
1830 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
1832 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
1833 style block comment is no longer considered an error.
1835 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
1837 * PLUGIN/guile.libs.in: New file.
1838 * PLUGIN/guile.libs: Removed from repository.
1839 * configure.in: Create PLUGIN/guile.libs from
1840 PLUGIN/guile.libs.in. This is for including additonal libraries
1841 needed for dynamic linking.
1842 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
1843 instead of PLUGIN/guile.libs.
1845 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
1847 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
1849 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
1850 occurrences of the given element from the list, not just the
1851 first. This is how the Emacs Lisp functions behave, how the
1852 analogous Common Lisp functions behave, and (I believe) how the
1853 older Maclisp functions worked. I realize that this change may
1854 break code, but it seemed better to break it before the Guile
1857 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
1858 Their prototypes were already present in gc.h, but they weren't
1860 (scm_init_storage): Initialize scm_protects.
1861 * root.c (scm_protects): New element of scm_sys_protects.
1863 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
1865 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1867 * libguile.h: Added #include "libguile/net_db.h".
1869 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
1870 30 change. That file is only meant for communication between the
1871 configuration process and load.c. If code linked against libguile
1872 wants to get at the paths mentioned in libpath.h, it can call
1873 functions declared in load.h.
1875 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1877 * libguile.h: Removed #include "libguile/fdsocket.h"
1879 * net_db.c: Added #include <sys/socket.h>.
1881 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
1883 * filesys.c (scm_input_waiting_p): use select in preference to
1884 FIONREAD, since the latter doesn't detect EOF.
1885 Throw error if neither select nor FIONREAD available.
1887 * socket.c (scm_connect): take a port, not a fd object.
1888 (scm_fill_sockaddr): throw an error if fam is not recognised.
1889 (scm_bind): use scm_fill_sockaddr.
1890 (scm_listen): take a port, not a fd object.
1891 (scm_accept): take and return a port. return #f in the car if
1892 address can't be got
1893 (scm_sock_fd_to_port): new procedure.
1894 (scm_socket): use scm_sock_fd_to_port.
1895 (scm_addr_vector): throw error if unrecognised address type.
1896 take an extra argument with the calling procedure name.
1897 (scm_getsockname): take a port. return #f if address can't be got.
1898 (scm_getpeername): take a port. return #f if address can't be got.
1899 (scm_recvfrom): take a port. return #f for address component if can't
1901 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
1902 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
1904 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
1906 * throw.c (scm_internal_catch): Make body funcs and handler funcs
1907 use separate data pointers, to allow them to be designed
1908 independently and reused.
1909 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
1910 Renamed from catch_body, catch_handler, and uncaught_throw; made
1912 (struct scm_catch_body_data): Renamed from catch_body_data; moved
1914 (scm_catch): Use the above.
1915 (scm_throw): Don't bother printing a message for an uncaught
1916 throw; we establish a default handler in init.
1917 * throw.h (scm_internal_catch): Prototype updated.
1918 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
1920 (struct scm_body_thunk_data): New structure, used as data
1921 argument to scm_body_thunk.
1922 * init.c (struct main_func_closure): New structure, packaging up
1923 the data to pass to the user's main function.
1924 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
1925 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
1926 scm_internal_catch to establish a catch-all handler, using
1927 scm_handle_by_message. This replaces the special-case code in
1929 (invoke_main_func): Body function for scm_internal_catch; invoke
1930 the user's main function, using the main_func_closure pointer to
1931 decide what to pass it.
1932 * root.c (struct cwdr_body_data): Remove handler_proc member.
1933 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
1934 (cwdr_handler): Removed.
1936 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1938 * socket.h (SCM_P): update bind prototype.
1939 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
1940 include "feature.h".
1941 (scm_socket): return a port, not a file descriptor object.
1942 include "fports.h" and <unistd.h>
1943 (scm_bind): take a port, not a file descriptor object.
1944 take an extra argument for address args.
1946 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
1947 INADDR_NONE, INADDR_LOOPBACK.
1949 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1951 * init.c: include net_db.h and not fdsocket.h.
1952 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
1954 * Makefile.am: corresponding changes.
1955 * socket.h: renamed from fdsocket.h, fix names.
1956 * net_db.h: renamed from socket.h, fix names.
1957 * socket.c: renamed from fdsocket.c.
1958 remove _sys from procedure names.
1959 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
1960 add "socket" to features list.
1961 * net_db.c: renamed from socket.c.
1962 remove _sys from procedure names.
1963 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
1964 add "net-db" to features list.
1965 include "net_db.h". don't include <sys/socket.h> or
1968 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1970 * tags.h (scm_tags): Removed comma at end of last enumerator.
1972 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
1974 Don't use GCC extensions to allocate space for debugging frames.
1975 (Here he goes again! Why do we put up with this?!)
1976 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
1977 an scm_debug_info structure, not an in-line array of them. Add
1978 'info' member, to say how many vect elements we've used, for eval
1980 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
1981 a new variable debug_info_end to mark the end of vect, instead of
1982 the address of the 'info' pointer itself.
1983 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
1984 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
1985 (SCM_APPLY): Explicitly allocate space for debug.vect.
1986 * debug.c (scm_m_start_stack): Same, for vframe.vect.
1987 * stacks.c: Adjusted for new debug frame structure.
1988 (RELOC_INFO, RELOC_FRAME): New macros.
1989 (stack_depth, read_frames): Use them, and new scm_debug_frame
1990 element 'info', instead of magically knowing that eval frames have
1991 an info pointer sitting after vect.
1992 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
1994 (scm_init_stacks): Formatting tweaks.
1996 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
1998 Give GCC more control flow information, so it can be sure that
1999 variables aren't used uninitialized.
2000 * error.h (scm_error, scm_syserror, scm_syserror_msg,
2001 scm_sysmissing, scm_num_overflow, scm_out_of_range,
2002 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
2003 scm_misc_error): Tell GCC that these functions never return.
2004 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
2005 out the field type, call abort if SCM_ASSERT returns, to placate
2007 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
2008 scm_wta ever returns. We can't handle this case anyway, and this
2009 gives the optimizer more information.
2010 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
2011 scm_wta ever returns.
2013 In some cases, the code is fine, but GCC isn't smart enough to
2014 figure that out; this usually happens when one variable is only
2015 initialized and used when a particular condition holds true, and
2016 we know that condition will never change within a given invocation
2017 of the function. In this case, we simply initialize the variables
2018 to placate the compiler, hopefully to a value which will cause a
2019 crash if it is ever actually used.
2020 * print.c (scm_iprin1): Initialize mw_pos.
2021 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
2022 * throw.c (scm_ithrow): Initialize dynpair.
2023 * unif.c (scm_uniform_vector_ref): Initialize cra.
2024 * struct.c (init_struct): Initialize prot.
2025 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
2027 * strports.c (scm_eval_0str): Don't return uninitialized garbage
2028 if EXPR contains no expressions.
2030 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2032 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
2033 cause an infinite loop (???). So much for the algebraic
2034 equivalency of variable-sized arrays and alloca...
2036 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
2038 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
2039 a SCM boolean, not a C boolean.
2041 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
2043 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
2044 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
2045 rules for raising scm_mtrigger. Previously, unfortunate but not
2046 unlikely circumstances could result in almost constant invokation
2047 of the gc. Now, this situations should be less likely, but they
2048 are not prevented completely.
2050 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
2052 * numbers.c (scm_fuck): Procedure removed; looks like old test
2054 * numbers.h: Prototype removed.
2056 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
2058 * debug.h (scm_debug_frame): Change `vect' member from an in-line
2059 array to a pointer, to match my Nov 21 change in eval.c.
2061 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2063 * libguile.h: Added #include "libguile/backtrace.h", #include
2064 "libguile/stacks.h".
2066 * strings.c (scm_string scm_make_string scm_string_ref
2067 scm_string_set_x scm_string_equal_p scm_string_append):
2068 Bugfix according to scm patch from Aubrey Jaffer:
2069 Corrected long-standing
2070 (not (eqv? (integer->char 128)
2071 (string-ref (make-string 1 (integer->char 128)) 0)))
2072 bug found by John Kozak <jk@noontide.demon.co.uk>.
2074 * strports.c, strports.h: Make scm_eval_0str return the value of
2075 the last expression evaluated (previously, it returned void).
2077 * strports.c, strports.h: New function: scm_read_0str. Does what
2080 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2082 * simpos.c (scm_getenv): return #f if string can't be found in the
2083 environment instead of throwing an exception, for compatibility
2084 with numerous other systems.
2086 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
2088 * Makefile.am (.c.x): Use guile-snarf.
2089 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
2091 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
2093 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
2095 * backtrace.c (scm_display_error_message): Made non-static, and
2096 renamed from display_error_message.
2097 * backtrace.h (scm_display_error_message): Added extern decl.
2098 * throw.c (uncaught_throw): Use it to display the error message.
2100 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
2102 * inet_aton.c: Use #if 0, not #ifdef 0.
2104 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
2106 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
2107 to convert the returned value.
2108 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
2109 the offset argument.
2111 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
2113 Add new interface to catch/throw, usable from C as well as
2115 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
2116 (scm_internal_catch): New function, replaces...
2117 (scm_catch_apply): Deleted.
2118 * throw.c (scm_catch_apply): Deleted; replaced with a more general
2119 mechanism which is a bit more code, but can be used nicely from C
2120 and implement the Scheme semantics as well.
2121 (scm_internal_catch): This is the replacement; it's named after
2122 the analogous function in Emacs.
2123 (scm_catch): Reimplemented in terms of the above.
2124 (struct catch_body_data, catch_body, catch_handler): New
2125 functions, used by scm_catch.
2126 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
2127 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
2128 support for new cwdr.
2130 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
2133 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
2135 * acconfig.h: Added DYNAMIC_LINKING symbol.
2136 * configure.in: Add option and checks for dynamic linking.
2137 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
2138 dynl.h: New files for dynamic linking support.
2139 * Makefile.am (libguile_a_SOURCES):
2141 (modinclude_HEADERS): Added "dynl.h".
2142 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
2144 * init.c (scm_boot_guile_1): Call
2145 scm_init_dynamic_linking to initialize dynamic linking support.
2147 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
2149 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
2150 (as we Schemers say). It needs to be global, so that I can tweak
2151 it for the proper operation of unexec.
2152 (scm_boot_guile_1_live): New variable, see above.
2154 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
2156 * guile-snarf.sh: Removed.
2157 * PLUGIN/guile.libs: Added dependency for -lm.
2158 * acinclude.m4: Renamed from aclocal.m4.
2159 * PLUGIN/greet: Removed.
2160 * Makefile.am, aclocal.m4: New files.
2161 * configure.in: Updated for Automake.
2163 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
2165 * eval.c (scm_definedp): Use top_level_lookup_closure_var
2166 and not top_level_lookup_thunk_var.
2168 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
2170 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
2172 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
2174 * eval.c (scm_definedp): Incompatibly changed to be a builtin
2175 Scheme function, instead of syntax. Single argument is now a
2178 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2180 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
2181 scm_ra_divide): Properly terminate statements passed as arguments
2182 to IVDEP macros. (Thanks to Bernard Urban.)
2184 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
2185 with non-constant sizes. (Thanks to Bernard Urban.)
2187 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
2189 It's an "eval closure", not an "eval thunk." A thunk is a
2190 function of no arguments.
2191 * root.h (struct scm_root_state): Renamed
2192 top_level_lookup_closure_var from top_level_lookup_thunk_var.
2193 (scm_top_level_lookup_closure_var): Renamed from
2194 scm_top_level_lookup_thunk_var.
2195 * root.c (mark_root): Uses changed.
2196 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
2197 * init.c (scm_start_stack): Uses changed.
2198 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
2199 Change scheme-visible name to *top-level-lookup-closure* from
2200 *top-level-lookup-thunk*.
2202 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
2204 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
2205 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
2207 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
2209 * gc.c (struct scm_heap_seg_data): Doc fixes.
2211 * gc.c (scm_gc_sweep): Empty all segments' freelists before
2212 sweeping. Then, prepend each segment's free cells to its
2213 freelist, rather than wiping out the old value. (Thanks to Marius
2216 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
2217 scm_check_freelist, scm_debug_newcell): New functions and
2218 variables, for debugging freelist problems.
2219 * pairs.h (SCM_NEWCELL): New debugging version added.
2220 * gc.h (scm_debug_newcell): Added extern declaration, used by
2221 debugging version of SCM_NEWCELL.
2223 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2225 On some systems <libc.h> conflicts with <unistd.h>, and should not
2226 be #included at all.
2227 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
2228 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
2229 * configure.in: Call it.
2230 * posix.c, filesys.c: Use its results to decide whether or not to
2232 * configure, scmconfig.h.in: Rebuilt with autoconf and
2235 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2237 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
2238 pointer to the stdio stream before calling scm_setbuf0, so the
2239 latter will be able to retrieve it. I'm surprised this didn't
2240 segfault earlier. (Thanks to Christopher Lee.)
2242 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2244 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
2247 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2249 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
2250 number of stack narrowing specifier pairs. The first specifier in
2251 a pair controls inner border, the second the outer border. A
2252 number means cut that number of frames, a procedure object means
2253 cut until that object is found in operator position in a frame.
2255 * root.c (cwdr): Bugfix.
2257 * read.c: Recording of positions disabled by default.
2259 * procs.c (scm_closure_p): New function.
2261 * posix.c (scm_tmpnam): New function.
2263 * load.c: Added #include "throw.h".
2264 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
2267 * load.c, load.h (scm_read_and_eval_x): New function.
2269 * eval.c: Renamed debug option "deval" to "debug".
2271 (scm_eval_x): `eval!' is no longer accessible from the scheme
2272 level. Motivation: We can't allow operations which introduce
2273 glocs into the scheme level. Guile's type system can't handle
2274 these as data. Use `eval' or `read-and-eval!' as replacement.
2276 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
2277 SCM_CONSP since this is a macro!; Set vframe.prev to
2278 scm_last_debug_frame instead of 0. In this way we can look
2279 "above" the virtual start stack frame if we wish.
2280 (scm_debug_hang): New function: Useful for debugging Guile in
2281 certain tricky situations. Will probably be removed later...
2283 * debug.h: Changed semantics of debug option "backtrace". This
2284 option now only indicates whether we want automatic backtrace at
2287 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2289 * ports.c: #include "filesys.h"
2290 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
2292 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
2293 Motivation: This is system specific code which is related to file
2294 I/O. It also may use select. Added code by Gary Houston to
2295 detect presence of character in stdio buffers.
2297 * libguile.h: #include "libguile/libpath.h"
2299 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
2300 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
2301 SCM_SITE_DIR; Install libpath.h among the other include files.
2303 * load.c, load.h (scm_sys_package_data_dir): New function.
2305 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2307 * stacks.h: Bugfix: Don't use tail-array length field as stack
2308 length field! This screwed GC.
2310 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2312 * _scm.h: Added #ifndef around definition of macros min and max.
2314 * __scm.h: Added hooks for threads to plugin to in ints protection
2315 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
2316 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
2317 the main code in these macros duplicated and spread over multiple
2318 files. Renamed SCM_THREADS_SWITCHING_CODE ->
2319 SCM_THREAD_SWITCHING_CODE.
2321 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
2323 * snarf.h: New file.
2324 * guile-snarf.sh: New file.
2325 * Makefile.in (inner_h_files): Added snarf.h
2326 (ancillary, install, uninstall, distclean): Added actions for
2328 (.c.x): Use guile-snarf.
2329 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
2330 (gen_c_files): Note that these depend on guile-snarf.
2331 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
2332 now in "snarf.h". Added #include "snarf.h" to get them.
2333 * libguile.h: Added #include "snarf.h".
2334 (Patches applied and tweaked by Jim Blandy.)
2336 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
2338 * socket.c: Use K&R style declaration for 'close'; the GNU coding
2339 standards suggest against providing prototypes for system
2340 functions. Thanks to Greg Troxel.
2342 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
2344 * strports.c (scm_eval_0str): New function.
2345 #include "read.h", to get prototype for scm_read.
2346 * Makefile.in (strports.o): Update dependencies.
2347 * strports.h: New prototype.
2349 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
2350 scheme name from "int?" to "integer?". It seems to do the job.
2351 * numbers.h: Rename prototype too.
2352 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
2355 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
2356 scm_num_eq_p): Rename these according to R4RS conventions: call
2357 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
2358 to making libguile R4RS compliant without ice-9...
2360 * load.c (scm_sys_search_load_path): Search for files under all
2361 extensions listed in the %load-extensions variable. If FILENAME
2362 is absolute, return it unchanged, without searching the load path.
2363 (scm_loc_load_extensions): New variable, pointing to
2364 %load-extensions' value cell.
2365 (scm_init_load): Initialize it, and the value it points to.
2366 (scm_primitive_load_path): Improve error reporting.
2368 * load.c (scm_loc_load_hook): New variable, pointing to value cell
2369 of new Scheme variable %load-hook.
2370 (scm_primitive_load): Apply %load-hook to filename.
2372 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
2374 * configure.in: add tests for figuring out whether buffered data
2375 is available in a FILE structure, which is needed by char-ready.
2377 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
2380 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
2381 exceptions using misc_error instead of syserror. It seems a bit
2382 odd to throw an exception if a string can't be found in the
2383 environment, but it's consistent with open-file, stat etc.
2384 (simpos.h): remove sys_ from getenv.
2386 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
2387 occurs, throw an error instead of returning errno. Return value
2389 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
2391 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
2393 * filesys.c (scm_stat2scm): derive file type and permissions from
2394 the stat mode and append them to the returned vector.
2395 There isn't much overhead in doing this and it avoids the need to
2396 work with S_IRUSR et al. in Scheme.
2397 Define symbols scm_sym_regular etc.
2398 (scm_init_filesys): don't intern S_IRUSR etc.
2400 * load.c: change s_try_load and s_try_load_path to s_primitive_load
2401 and s_primitive_load_path.
2403 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
2405 * error.h: don't declare error symbols. prototype for scm_misc_error.
2407 * stackchk.c (scm_stack_overflow_key): defined here instead of in
2410 * error.c: use SCM_SYMBOL to set up error keys.
2411 scm_misc_error: new procedure.
2413 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2415 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
2416 between `#!' and `!#' is ignored.
2417 (skip_scsh_block_comment): New function.
2419 * feature.c (scm_set_program_arguments): New argument, FIRST.
2420 * feature.h: Update prototype.
2421 * init.c (scm_boot_guile_1): Pass new argument to
2422 scm_set_program_arguments.
2424 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
2426 * init.c (scm_start_stack): Don't initialize scm_progargs here.
2427 (scm_boot_guile): Call scm_set_program_arguments here, later than
2428 the old initialization.
2430 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
2431 initialization procedure.
2432 - Delete in, out, err arguments; there are other perfectly good
2433 ways to override these when desired.
2434 - Delete result argument; this function shouldn't ever return.
2435 - Rename init_func argument to main_func, for less confusion.
2436 - Delete boot_cmd argument; main_func is more general.
2437 -Add 'closure' argument, to help people pass data to main_func
2438 without resorting to global variables.
2439 - Abort if reentered; don't bother returning an error code.
2440 - Call scm_init_standard_ports to set up the default/current
2441 standard ports; no need to pass them to scm_start_stack.
2442 - Remove code to evaluate the boot_cmd, and start the repl; let
2443 the user do something like that in main_func if they want.
2444 - Remove code to package up a return value; main_func can do any
2446 - Call exit (0), instead of returning.
2447 (scm_start_stack): Don't initialize the I/O ports here; that's
2448 weird. Delete in, out, err arguments. Move guts to
2449 scm_init_standard_ports, scm_stdio_to_port.
2450 (scm_init_standard_ports): New function, to set up current and
2451 default standard ports.
2452 (scm_start_stack, scm_restart_stack): Make these static.
2453 * init.h (scm_boot_guile): Adjust declaration.
2454 (scm_start_stack, scm_restart_stack): Remove externally
2455 visible declarations for these.
2456 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
2458 * fports.c (scm_stdio_to_port): New function. Its guts used to be
2459 written out several times in scm_start_stack.
2460 * fports.h: New declaration for the above.
2462 * feature.c (scm_set_program_arguments): New function.
2463 * feature.h: New declaration for the above.
2465 * ports.c: Formatting tweak.
2467 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
2469 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
2470 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
2471 for obtaining the address of a car or cdr field. Motivation:
2472 &SCM_CXR make assumptions about the internal structure of the
2475 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
2476 Motivation: see SCM_CXRLOC.
2478 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
2479 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
2480 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
2481 Motivation: Safer use. Some other macros are defined in terms of
2482 these operations. If these are defined using the SCM_SETCXR
2483 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
2484 to inefficiency and an <e1> with side-effects could potentially
2485 break. Also, these particular operations are heavily utilized in
2486 the garbage collector. In unoptimized code there will be a
2489 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
2490 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
2491 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
2492 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
2493 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
2494 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
2495 vports.c: Cleaned up use of pairs: Don't make any special
2496 assumptions about the internal structure of selectors and
2497 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
2498 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
2499 (Among other things, this change makes it easier to build Guile
2500 with certain compilers which have problems with casted lvalues.)
2502 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2504 * stacks.c: Improve selection of relevant stack frames when making
2505 a stack object. Introduce one level of indirection in the stack
2506 object to make it possible to "narrow" to a certain region of the
2507 stack. This facilitates making use of more clever algorithms (not
2508 implemented) for selecting relevant frames and gives a cleaner
2509 design since selection of frames can be done independently of
2510 extraction of frames from the real stack.
2511 (scm_stack_id): Also take #t as argument which means look at
2514 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
2515 Turn n_tail into an integer directly representing current number
2516 of frames in stack. Add field tail.
2518 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
2520 * debug.c (scm_make_memoized): Made it available at scheme level.
2521 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
2522 SCM_NIMP before applying heavier predicates in argument checking.
2523 (scm_local_eval): Also take memoized object as argument.
2525 * backtrace.c (scm_display_error): Just a safety measure: Stacks
2526 aren't created with zero length, but should such a strange
2527 creature suddenly turn up...
2529 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
2531 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
2532 `del', for the sake of C++ compilers. (Patch applied by JimB.)
2534 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
2536 * variable.c (scm_make_variable): Make the name hint optional, as
2538 (anonymous_variable_sym): Renamed from variable_sym. All uses
2541 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
2542 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
2543 of scm_primitive_load_path was also changed to
2544 "primitive-load-path", from "%try-load-path". Callers changed.
2545 We'd like to respect the convention that a function named
2546 "try-mumble" should behave just like the function called "mumble",
2547 but return #f instead of signalling some error.
2548 * load.h: Rename prototypes.
2550 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2552 * print.c (make_print_state, grow_print_state), print.h: Modified
2553 the print state representation: Don't use a tail array for
2554 recording of circular references. Resizing of the print state
2555 structure invalidates the print state pointer. To avoid passing
2556 around an indirect print state reference to all printing
2557 functions, we instead let the print state reference a resizable
2560 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2562 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
2563 Don't crash when passed an improper list terminated by a
2564 non-immediate value.
2566 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
2568 Allocate data for structures on an eight-byte boundary, as
2569 required by the tagging system.
2570 * struct.c (alloc_struct): New function.
2571 (scm_make_struct, scm_make_vtable_vtable): Call it.
2572 * struct.h (scm_struct_n_extra_words): Bump to 3.
2573 (scm_struct_i_ptr): New "field".
2574 * gc.c (scm_gc_sweep): When we need to free the data, use the
2575 information stored by alloc_struct to find the beginning of the
2576 block allocated to the structure, so we can free it.
2578 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2580 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
2583 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
2584 (scm_debug_info): New member: id.
2586 * stacks.c: Stacks are now represented as structs; Stacks have an
2587 id given to them by `start-stack'.
2588 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
2590 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
2591 Changed stack representation.
2593 * debug.c (scm_procedure_name): Try procedure property `name' for
2594 compiled closures aswell.
2596 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
2598 * eval.c: scm_i_name moved to gsubr.c
2599 (scm_m_define): Record names of all kinds of procedure
2600 objects. (Earlier, only closures were recorded.)
2602 * procprop.h: Added declaration of scm_i_name.
2604 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
2605 (scm_make_gsubr): Record names of compiled closures.
2607 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2609 * debug.c, debug.h: Removed obsolete code.
2611 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
2612 stacks.c: Renamed regs --> scm_contregs.
2614 * print.c (scm_free_print_state): Cleanup print state before
2615 returning it to pool. It is better to do it here than in
2616 scm_prin1 since scm_prin1 is called often.
2618 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
2619 s_set_source_property_x): Check that first argument is a pair or a
2622 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
2623 scm_i_line, scm_i_column and scm_i_breakpoint global.
2625 * init.c: Added #include "backtrace.h" and #include "stacks.h".
2626 (scm_boot_guile_1): Added calls to scm_init_backtrace and
2629 * debug.h: Added debug object smob declaration and macro
2632 * configure.in: Build with backtrace.o and stacks.o if debug
2635 * Makefile.in: Added entries for new files: backtrace.c,
2636 backtrace.h, stacks.c and stacks.h.
2638 * symbols.c (scm_sym2ovcell): Fixed documentation.
2640 * _scm.h (min, max): Added.
2642 * async.c: Moved `min' macro to _scm.h.
2644 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
2645 SCM_BACKTRACE_INDENT.
2647 * eval.c: Added new debug options `maxdepth' and `indent'.
2649 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
2651 * print.h: Added selector SCM_PRINT_STATE.
2653 * print.c: New functions: scm_make_print_state,
2654 scm_free_print_state.
2656 * print.h: Added declarations for scm_make_print_state,
2657 scm_free_print_state.
2659 * debug.c (scm_m_start_stack): New acro.
2661 * debug.h: Small cleanup.
2663 * init.c (scm_boot_guile_1): Moved scm_init_debug below
2666 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

2686 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,

2688 declare functions with prototypes. (Patch thanks to Marius
2691 More prototype-related changes from Marius Vollmer:
2692 * gdb_interface.h: Wrapped header file in #ifdef/#endif
2693 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
2694 * ports.h (ptobfuns): Added prototypes. This means some casting in
2696 * fports.c: Added casts for initializations, since the functions
2697 are defined to take FILE * as their stream argument, not SCM.
2698 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
2699 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
2700 to `char *str_data' to conform to prototype.
2702 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2704 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
2706 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
2708 * stime.c, stime.h: use SCM_P method.
2710 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2712 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
2713 be given at least two arguments. Insist that lst's last element
2714 be a list, but don't make any requirements of its predecessors.
2716 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2718 * eval.c (scm_nconc2last): Revert last change; there seems to be
2719 other stuff going on here.
2721 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2723 * eval.c (scm_nconc2last): Make sure that each element of lst
2724 (which is a list of argument lists, except for the tail) is a
2725 proper list, i.e., finite and terminated by '().
2727 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
2729 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
2732 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
2733 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
2736 * vectors.c (scm_make_vector): Fill vectors with the undefined
2737 value, to help make Guile Scheme code more portable to other
2740 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
2741 * symbols.h, tags.h: Doc fixes.
2743 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
2745 * async.c (scm_take_signal): Doc fixes.
2747 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
2749 * numbers.c (scm_divbigint): When the remainder is zero, we don't
2750 want to subtract it from the modulus; we just want to leave it
2753 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
2755 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
2758 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
2760 * throw.c (scm_catch_apply): Finished implementation of
2763 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2765 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
2767 (scm_init_filesys): set "i/o-extensions" feature.
2770 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
2772 * Makefile.in (root.o): Correct dependencies.
2774 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
2776 * Makefile.in: Added dependency entry for root.o.
2778 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
2779 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
2781 * init.c (scm_start_stack): Set initial root continuation number
2784 * procs.c: New function: scm_thunk_p.
2786 * procs.h: Added declarations of scm_thunk_p.
2788 * root.c: Renamed `call-with-new-root' -->
2789 `call-with-dynamic-root'.
2790 (cwdr): Removed allocation of new root state. This should be done
2791 separately by use of scm_make_root.
2792 (scm_apply_with_dynamic_root): New function: Does what it
2793 sounds like. Needed when spawning threads.
2795 * root.h: Added member last_debug_frame to root state.
2796 Added #include "libguile/debug.h"
2798 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
2799 arguments. The motivation is that code in root.c needs catch
2800 functionality, and we want to avoid code duplication.
2801 New functions: scm_catch, scm_lazy_catch. These are wrappers for
2802 scm_catch_apply. scm_lazy_catch is intended to introduce catch
2803 handlers that run without popping the stack into the dynwind
2806 * throw.h: Added prototypes for scm_catch_apply and
2809 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2811 * root.h (scm_root, scm_set_root): Decouple thread support details
2812 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
2813 SCM_SET_THREAD_LOCAL_DATA.
2815 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
2816 and tortoise scanning loop.
2818 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
2820 * Makefile.in: Rebuild dependencies.
2822 * libguile.h: #include "libguile/print.h" before "smob.h", since
2823 the latter uses the print_state structure.
2825 * throw.c (scm_ithrow): Use the correct variable when checking to
2826 see if a given element of scm_dynwinds is a valid catch.
2828 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
2829 structure, abort; don't just silently ignore the garbage.
2831 * _scm.h: #include "print.h" here, since it seems to be used just
2833 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
2834 strports.c, unif.h: Don't #include "print.h".
2836 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2838 * feature.h (scm_loc_features): Removed external declaration.
2839 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
2841 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2843 * feature.c (scm_init_feature): Added threads feature (needs to be
2844 initialized here, since features doesn't exist when
2845 scm_init_threads is called).
2847 * libguile.h: Added #include "libguile/../threads/threads.h".
2848 (This is a kludge to get thread support working. This should be
2851 * configure.in, acconfig.h: Added flags for thread support.
2853 * scmsigs.c: Define `signal' to be `pthread_signal' if using
2856 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
2857 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
2860 * _scm.h: Added conditional #include "threads.h"
2862 * __scm.h (SCM_ASYNC_TICK): Added call to macro
2863 SCM_THREADS_SWITCHING_CODE.
2865 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
2866 allocate the basic dynamic root object.
2867 (scm_boot_guile): Added call to scm_init_root.
2869 * root.c, root.h: Added root smob.
2870 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
2871 functions: Implements dynamic roots mostly according to spec in
2872 SCM manual. Main difference is that the second argument is a
2873 throw handler rather than an error "thunk".
2875 * root.h: Added declaration of scm_init_root.
2877 * root.c: Added #include "genio.h", #include "smob.h", #include
2878 "pairs.h", #include "throw.h", #include "dynwind.h", #include
2880 (scm_init_root): Added #include "root.x".
2882 * throw.c: Added #include "stackchk.h"
2883 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
2884 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
2885 can be used in scm_call_with_new_root; Added reenabling of stack
2886 checking when catching a throw.
2888 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
2890 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
2892 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
2893 element is not found, as per R4RS.
2895 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2897 * list.c: Doc fixes throughout.
2899 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2901 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
2902 declare the char * to be const. Avoids a warning in rgx.c.
2904 * ports.h: spelling fix.
2906 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
2909 * load.c (scm_sys_try_load_path): throw an error if file not found
2910 (like it says it in NEWS).
2912 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2914 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
2915 PROPS slot to '(), not #f; it's an empty alist.
2917 * throw.h, throw.c: Use SCM_P instead of #if hair.
2919 Remove special support for uncaught throws; see throw.c for
2921 * throw.c (uncaught_throw): New function.
2922 (scm_ithrow): Call uncaught_throw if we don't find a throw
2923 target; don't mess with scm_bad_throw_vcell.
2924 (scm_bad_throw_vcell): Variable deleted.
2925 (scm_init_throw): Don't initialize it.
2927 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
2930 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2932 * numbers.c (scm_istr2int): If the number is short (as most
2933 numbers are), just call scm_small_istr2int to deal with it.
2934 (scm_small_istr2int): New function, created by un-#ifdefing the
2935 non-bignum version of scm_istr2int and renaming it.
2937 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
2939 * load.c (scm_sys_try_load): don't check whether value returned
2940 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
2941 Change the Scheme name from %try-load to primitive-load.
2943 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
2944 Can avoid passing a message, allowing it to be derived in the
2945 error handler (e.g., if we want to throw to the key both from
2948 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
2950 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
2951 references now have a new appearance which is more compact and
2952 also gives a clue about what the target of the reference is.
2953 By setting parameters in the print state, more fancy printing can
2954 be achieved. This is used by the (not yet commited) backtrace
2957 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
2959 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
2962 * print.c: Added #include "struct.h". Removed function
2965 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
2966 scm_iprin1. Removed prototype for scm_prlist.
2968 * arbiters.c (prinarb),
2969 async.c (print_async),
2970 debug.c (prindebugobj, prinmemoized),
2971 eval.c (prinprom, prinmacro),
2972 filesys.c (scm_fd_print, scm_dir_print),
2974 mallocs.c (prinmalloc),
2975 numbers.c, numbers.h (scm_floprint, scm_bigprint),
2976 smob.h (scm_smobfuns),
2977 srcprop.c (prinsrcprops),
2979 unif.c, unif.h (scm_raprin1, rapr1),
2980 variable.c (prin_var): Changed argument `int writing' to
2981 `scm_print_state *pstate'.
2983 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
2984 that it will be called before scm_init_print.
2986 * print.c (scm_prin1): Print states are now allocated when calling
2987 scm_prin1 and then passed around to all printing functions as an
2988 argument. A cache `print_state_pool' enables reuse of print
2990 (scm_make_print_state): New function.
2991 (scm_iprin1): Adaption to print states.
2992 (scm_iprlist): An initial "hare and tortoise" scan brings down
2993 time complexity to O (depth * N). (Better time complexity will be
2994 achieved when the printing code is completely rewritten.)
2996 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2998 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
2999 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
3000 it gets done whether or not the cache variable has a value.
3002 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3004 Distinguish #f and ().
3005 * __scm.h: #undef SICP.
3006 * pairs.h (SCM_EOL): Delete this definition, equating it with
3008 * tags.h (SCM_EOL): Give it a new definition here; I think I found
3009 the value it used to have. Doc fixes, too.
3011 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
3013 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
3014 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
3015 Lord's implementation of structs, allowing for tail arrays as
3016 described in the manual. Also fixed some bugs. (Both the interface
3017 and the implementation should be improved.)
3019 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
3021 * print.c, print.h: Closures now print like #<procedure foo (x)>.
3022 People who whish to see the source can do `(print-enable 'source)'.
3023 Removed #ifdef DEBUG_EXTENSIONS.
3025 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
3027 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
3028 integer (assuming for now accepting an integer is a good thing).
3030 * error.c, fports.c: replace use of %S in lgh_error args with %s.
3031 %S will be used instead for write'ing arguments.
3033 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
3034 asserts. fix a few other asserts.
3035 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
3036 scm_uniform_vector_ref, scm_array_set_x,
3037 scm_dimensions_to_unform_array): change args in
3038 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
3039 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
3040 scm_substring_fill_x): likewise.
3041 gsubr.c (scm_gsubr_apply): likewise.
3042 eval.c (SCM_APPLY): likewise.
3044 * eval.c (4 places): replace scm_everr with lgh_error or
3047 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
3048 scm_memory_error): new procedures.
3049 scm_everr: deleted. can use scm_wta, dropping first two args.
3050 scm_error: convert NULL subr to SCM_BOOL_F.
3052 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
3055 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
3058 * error.c, error.h: new error keys: scm_arg_type_key,
3059 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
3061 scm_wta: reimplement using lgh_error instead of scm_everr.
3063 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
3065 * gdbint.c: scm_lread now has one more argument.
3067 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
3068 scm_port_\1; Added mutator scm_set_port_filename_x (used when
3069 loading source from non-file ports, which, e. g., happens when
3070 using the Emacs interface).
3072 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
3075 * read.c: Added code for recording of positions of source code
3076 expressions; New functions: recsexpr, scm_lreadrecparen;
3077 _scm_make_srcprops --> scm_make_srcprops
3078 (scm_flush_ws): Removed updating of positions counters. This work
3079 is already done by scm_gen_getc
3081 * read.h: Added prototype for scm_lreadrecparen
3083 * print.c: Added #include "alist.h"
3085 * eval.c: Added #include "hash.h"
3087 * eq.c: Added #include "ramap.h"
3089 * options.c: Documentation fixes.
3091 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
3092 (scm_init_srcprop): Adjusted size of initial source-whash. Name
3093 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
3094 --> scm_make_srcprops
3096 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
3097 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
3098 function calls in the definition of the whash access macros.
3100 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
3102 * init.c (scm_boot_guile): Add level of indirection to
3103 scm_boot_guile_1() to ensure that stack base pointer is properly
3104 initialized. There was no guarantee that variable i was the
3105 highest/lowest variable on stack (i.e. the call frame of
3106 scm_boot_guile was not completely protected from gc).
3108 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
3110 * ports.h (scm_port_table): put back file_name, it will be used to
3111 support debugging. Undo related changes in fports.c, ioext.c,
3114 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
3116 * ports.h (scm_port_table): remove file_name member for now, it seems
3118 * fports.c (scm_open_file): don't set file_name in PTAB.
3119 (prinfport): don't use file_name in PTAB.
3120 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
3121 * ports.c (scm_add_to_port_table): don't intialize file_name.
3122 (scm_port_file_name): remove for now.
3123 * gc.c (scm_gc_mark): don't mark PTAB file_name.
3125 * fports.h (scm_mkfile): prototype deleted.
3126 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
3128 * debug.c, unif.c: use scm_out_of_range instead of
3129 wta for range errors (ASSERT still needs work).
3131 * error.c, error.h (scm_out_of_range): new procedure.
3133 * error.c, error.h (scm_out_of_range_key): new key.
3135 * posix.c (scm_sync): #else was missing.
3137 * error.c, error.h: append _key to names scm_num_overflow and
3140 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
3141 of consing an empty list.
3142 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
3143 of macros, saves code and string space.
3144 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
3145 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
3146 lower case. Rename scm_syserror_m to scm_syserror_msg.
3147 error.h: prototypes for new procedures.
3149 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
3151 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
3153 * error.c, error.h: setup scm_num_overflow key.
3155 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
3156 Remove definition of SCM_OVSCM_FLOW.
3158 * fports.c (scm_open_file): use SCM_SYSERROR_M.
3160 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
3161 explicit message and args.
3163 * error.c, error.h, __scm.h: change system_error_sym to
3166 * error.c (system_error_sym): remove leading %% from the Scheme name
3169 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
3171 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3173 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
3174 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
3175 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
3176 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
3177 renamed. (These were introduced by unsupervised name
3180 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3182 * print.c: Added code for detection of circular references during
3183 printing. (init_ref_stack, grow_ref_stack): New functions. Added
3184 a hook for printing of closures (accessible via print options).
3185 This leads to a split of calls to scm_iprin1 into two classes:
3186 elementary print operations (e. g. the code which prints a smob)
3187 still use scm_iprin1 while top level calls (like scm_display) use
3188 scm_prin1. scm_prin1 begins by clearing the data structure used
3189 to record reference information.
3191 * print.h: Added declarations of scm_prin1 and scm_prlist.
3193 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
3195 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
3197 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
3199 * error.c (err_head): scm_iprin1 --> scm_prin1
3201 * debug.c: Adjusted header comment.
3205 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
3207 * strerror.c: Doc fix.
3209 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3211 * gdbint.c (gdb_read): Now possible to run during GC.
3212 (unmark_port, remark_port): New functions.
3214 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
3216 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
3217 of allocating a new string object. Also, increase size by
3218 the factor 2 instead of 1.5.
3220 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
3222 * __scm.h (SCM_P): Corrected to run under traditional C.
3224 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
3227 * async.c: Calls to scm_sysintern corrected.
3229 * async.h (scm_async_clock): Redundant declaration removed.
3231 * continuations.c (scm_dynthrow): Redundant declaration removed.
3233 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
3234 Definition typos corrected.
3236 * debug.h: Missing declarations of functions in debug.c added
3239 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
3240 Missing declarations to functions in eval.c added.
3242 * filesys.c: Possibly uninitialized variable rv.
3244 * gc.h (scm_object_addr, scm_unhash_name): Missing
3245 declarations of functions defined in gc.c added.
3247 * genio.c: Possible typos str_data -> wstr_data. ???
3249 * genio.c: Possibly unintended shadowing of local variable
3250 `int c' (gotos out of scope of inner `c'). ???
3252 * init.c: Uninitialized `SCM last' may be used.
3254 * ioext.h: (scm_sys_isatty_p): Typo.
3256 * list.h (scm_list_head): Missing prototype for function in
3259 * numbers.c (scm_two_doubles): Changed from extern to static
3260 (is used only within numbers.c).
3262 * numbers.h: Repeated declarations removed.
3264 * ports.h (scm_close_all_ports_except): Declaration for the
3265 function defined in ports.c added.
3267 * posix.h: Missing declarations added.
3269 * procs.h (scm_make_subr_opt): Missing declaration added.
3271 * socket.h (scm_sys_gethost): Missing declaration added.
3273 * socket.h: Redundant declarations removed (they are in fdsocket.h).
3275 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
3276 Missing declarations added.
3278 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
3280 * struct.c: Uninitialized variable `SCM answer' may be used.
3282 * unif.c (l2ra): Declaration prototype.
3284 * unif.c (scm_array_equal_p): Dummy definition removed (it is
3285 defined in ramap.c).
3287 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
3288 Redundant declarations removed (they are in ramap.h).
3290 * variable.h (scm_make_udvariable,
3291 scm_make_undefined_variable): Declaration corrected to
3292 correspond variable.c.
3294 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
3295 Missing declarations added.
3297 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
3299 * Makefile.in (distclean): Don't forget to delete fd.h.
3301 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3303 * fd.h.in, tags.h: Trivial cleanups.
3305 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
3306 marksweep.h just declared functions from gc.c.
3307 * gc.h, libguile.h: Don't #include "marksweep.h".
3308 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
3309 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
3310 dependencies updated.
3312 * libguile.h: Don't #include "files.h"; it's been deleted.
3314 * files.c (scm_sys_delete_file): Moved to filesys.c.
3315 File is now empty; deleted.
3317 * filesys.c: scm_sys_delete_file is now here. Remove
3318 #if's; they seem to rely on remnants of an old portability
3319 regimen. If the problems come up again, solve them properly,
3320 using autoconf. Specifically: Don't test M_SYSV, and #define
3321 remove to be unlink if it's #defined; don't use remove just
3322 because HAVE_STDC_HEADERS is #defined.
3323 * filesys.h: Add declarations for scm_sys_delete_file.
3324 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
3325 files.o, files.h, files.c, and files.x.
3326 * init.c: Don't #include "files.h", and don't call scm_init_files.
3328 Use SCM_P instead of PROTO; the latter intrudes on the user's
3330 * params.h: Deleted; definition of SCM_P moved to...
3331 * __scm.h: ... here, where it replaces PROTO macro.
3332 * libguile.h, smob.h: Don't #include "params.h".
3333 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
3334 smob.h: Fix prototypes accordingly.
3335 * Makefile.in: Update dependencies.
3336 (inner_h_files): Remove params.h.
3338 * gc.c: #include "gc.h"; every module should include its header,
3339 to let the compiler cross-check the declarations against the
3342 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
3343 simpos.h: #include "libguile/__scm.h".
3345 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
3347 * init.c: Don't forget to #include smob.h and init.h.
3348 * Makefile.in: Dependencies updated.
3350 * smob.h: Use PROTO instead of #if __STDC__.
3352 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
3354 * __scm.h: Doc fixes.
3356 * __scm.h, libguile.h: Use "quotes" in the #includes, not
3357 <angles>; this allows `make depends' to work properly.
3359 * libguile.h: #include smob.h and pairs.h before the others; they
3360 define typedefs used by other headers.
3362 C files should #include only the header files they need, not
3363 libguile.h (which #includes all the header files); the pointless
3364 recompilation was wasting my time.
3365 * Makefile.in (all .o dependency lists): Regenerated.
3366 * libguile.h: Don't try to get a definition for size_t here...
3367 * __scm.h: Do it here.
3368 * _scm.h: Since this is the internal libguile header, put things
3369 here that all (or a majority) of the libguile files will want.
3370 Don't #include <libguile.h> here; that generates dependencies on
3371 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
3372 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
3373 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and
3375 * alist.c: Get "eq.h", "list.h", "alist.h".
3376 * append.c: Get "append.h", "list.h".
3377 * arbiters.c: Get "arbiters.h", "smob.h".
3378 * async.c: Get "async.h", "smob.h", "throw.h", "eval.h".
3379 * boolean.c: Get "boolean.h".

3472 * stackchk.h: #include "libguile/debug.h",
3474 * print.h, read.h: #include "options.h", since everyone who uses
3475 either of these files will need that.
3477 * smob.h: #include "ports.h", "genio.h", and "print.h", since
3478 anyone who uses this file will need them to define the smob
3479 printing functions. Also, get markers.h, since people will need
3480 to #define the mark functions.
3482 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
3483 * ports.h: ... to here.
3485 * ports.h (scm_port_table_size): Explicitly give type as 'int';
3486 don't rely on archaic C default type rules.
3488 * fports.h: #include "libguile/ports.h", since you need that in
3489 order to parse this.
3491 * genio.h: #include "libguile/print.h", because you need that to
3492 parse this; don't bother #including "ports.h", since print.h gets
3495 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
3497 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
3498 this; it's now a reference to an element of *scm_root.
3500 * debug.h: Don't #include "options.h"; the compiler won't be able
3501 to find that once the headers are installed; instead, #include
3502 "libguile/options.h".
3503 * gc.h: Same, with marksweep.h.
3504 * mbstrings.h: Same, with symbols.h.
3505 * scmhob.h: Same, with _scm.h.
3506 * smob.h: Same, with params.h.
3508 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
3509 C files; there's no need for this, and it forces recompilations
3512 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
3514 * error.c (scm_error): declare scm_error_callback.
3516 * error.h: prototype for scm_error_callback.
3518 * __scm.h: define lgh_error.
3519 (SCM_SYSERROR): redefine using lgh_error.
3521 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
3523 * error.c (scm_error): new procedure.
3525 * error.h: prototype for scm_error.
3527 * Makefile.in (install): install scmconfig.h from the current
3528 directory, not $(srcdir).
3530 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
3532 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3533 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3534 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
3535 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
3536 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,

3539 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
3540 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3541 vports.h, weaks.h: #include "libguile/__scm.h", not
3542 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
3543 dependencies are within libguile properly.
3545 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
3547 * Makefile.in (.c.x): Simplify; there's no need to run this rule
3548 when scmconfig.h doesn't exist.
3550 * load.c (scm_sys_try_load): Correct spelling.
3552 * feature.c (scm_loc_features): Make this static.
3554 * Makefile.in (libpath.h): Omit trailing slash from path. We
3555 shouldn't require it of users, so why put it here?
3557 Move code to initialize and search %load-path from ice-9 to C
3558 code, so we can use the load-path to find the ice-9 boot code;
3559 this makes it easier to run Guile without installing it. See
3560 corresponding changes in guile/Makefile.in.
3561 * feature.c: Move stuff concerned with the load path to load.c.
3562 (scm_compiled_library_path): Deleted.
3563 Don't #include libpath.h here.
3564 * feature.h: Don't mention scm_compiled_library_path.
3565 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
3566 <sys/stat.h>, and <unistd.h> (if present).
3567 (R_OK): #define if the system hasn't deigned to.
3568 (scm_loc_load_path): New variable.
3569 (scm_init_load_path, scm_sys_search_load_path,
3570 scm_sys_try_load_path): New functions.
3571 (scm_init_load): Initialize scm_loc_load_path to point to the
3572 value cell of the Scheme %load-path variable.
3573 * load.h: Add declarations for scm_sys_search_load_path,
3574 scm_sys_try_load_path.
3575 * init.c: Call scm_init_load_path.
3576 * Makefile.in (feature.o, load.o): Dependencies updated.
3578 * load.c, load.h: Rewrite using PROTO macro.
3580 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3582 * gc.c (scm_cellp): New function: C predicate to determine if an
3583 SCM value can be regarded as a pointer to a cell on the heap.
3585 * gc.h: Added declaration of scm_cellp.
3587 * gdb_interface.h: New file: The GDB interface header from the GDB
3590 * gdbint.c: New file: GDB interface.
3592 * gdbint.h: New file: GDB interface.
3594 * libguile.h: Added #include <libguile/gdbint.h>.
3596 * init.c (scm_boot_guile): Added scm_init_gdbint.
3598 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
3599 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
3600 found if object files and source are kept separate).
3602 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
3604 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
3606 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
3608 * configure.in: Don't substitute the values of TCL_SRC_DIR and
3609 TK_SRC_DIR; they're not relevant any more.
3611 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
3612 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
3614 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
3616 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
3617 search path, so we can find the <libguile/MUMBLE.h> headers.
3619 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
3621 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
3622 implicit in the .c.o rule.
3623 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
3626 Put the library path in a header file, instead of passing it on
3627 the command line in every compilation.
3628 * Makefile.in (libpath.h): New target.
3629 (feature.o): Depend on libpath.h.
3630 (clean): Delete libpath.h.
3631 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
3632 * feature.c: ... #include "libpath.h" here.
3633 * .cvsignore: Ignore libpath.h.
3635 Don't install the unwashed masses of Guile header files in the
3636 main #include path; put most of them in a subdirectory called
3637 'libguile'. This avoids naming conflicts between Guile header
3638 files and system header files (of which there were a few).
3639 * Makefile.in (pkgincludedir): Deleted.
3640 (innerincludedir): New variable; this and $(includedir) are enough.
3641 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
3642 (installed_h_files): Divide this up. Now this variable lists
3643 those header files which should go into $(includedir) (i.e. appear
3644 directly in the #include path), and ...
3645 (inner_h_files): ... this new variable says which files appear in
3646 a subdirectory, and are referred to as <libguile/mumble.h>.
3647 (h_files): List them both.
3648 (install): Create innerincludedir, not pkgincludedir. Put
3649 the installed_h_files and inner_h_files in their proper places.
3650 (uninstall): Corresponding changes.
3651 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3652 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3653 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
3654 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
3655 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
3656 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
3657 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
3658 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
3659 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3660 vports.h, weaks.h: Find __scm.h in its new location.
3661 * __scm.h: Find scmconfig.h and tags.h in their new locations
3662 (they're both "inner" files).
3664 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
3666 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).

3670 * posix.c: Doc fixes.
3672 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
3674 * socket.c: Don't include a prototype for inet_aton; just use a
3675 K&R style declaration, to avoid warnings but minimize the chance
3676 of conflicts with the system.
3678 On NextStep, <utime.h> doesn't define struct utime, unless we
3679 #define _POSIX_SOURCE before #including it.
3680 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
3681 * acconfig.h: New comment text for above CPP symbol.
3682 * configure.in: Call it.
3683 * posix.c: #define _POSIX_SOURCE if it seems necessary.
3685 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
3687 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
3688 testing for __EMX__.
3690 * posix.c: #include <libc.h>, if it exists.
3692 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
3693 don't even know if the latter exists.
3695 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
3696 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
3697 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
3699 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
3701 (scm_init_posix): Use them when initializing the Scheme constants
3704 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3706 * Makefile.in (libdir, includedir, bindir): Use the
3707 autoconf-supplied values, instead of deriving them ourselves.
3708 (pkgincludedir, datadir, pkgdatadir): New variables.
3709 (install, uninstall): Put the header files in a special
3710 subdirectory, not in the main search path.
3712 * Makefile.in (ALL_CFLAGS): Provide the proper value for
3713 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
3715 * Makefile.in (IMPLPATH): Deleted; never used.
3717 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
3718 on the Tcl/Tk source any more.
3719 (INCLUDE_CFLAGS): Remove references to the above.
3721 * Makefile.in (version.o): Corrected dependencies.
3723 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
3725 * libguile.h: #include "version.h"
3727 * init.c (scm_boot_guile): Call scm_init_version.
3728 * gscm.c (gscm_run_scm): Call scm_init_version.
3730 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
3731 GUILE_VERSION): AC_DEFINE these.
3732 (acconfig.h): #undef the above symbols.
3734 * Makefile.in (libobjs): Add version.o.
3735 (installed_h_files): Add version.h.
3736 (c_files): Add version.c.
3737 (gen_c_files): Add version.x.
3738 (version.o): New rule.
3739 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
3740 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

3749 weaks.o): Add version.h to dependency lists.
3750 (markers.o): Remove duplicate rule.
3752 * version.h: New file.
3754 * version.c: New file.
3756 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3758 * symbols.c (scm_strhash): scm_downcase is now a function, not an
3759 array; use it appropriately. Since GCC is quite happy to
3760 subscript functions, it never warned us about this; we should use
3761 -Wpointer-arith in the future. I guess we never tested
3764 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3766 * socket.c: Doc and copyright fixes.
3768 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3770 * debug.c: Fixed and improved gdb support.
3772 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3774 * socket.c: Added declaration of inet_aton to avoid compiler
3775 warning. (Hope this solution is correct.)
3777 * stime.c: Added declaration of ftime. (This is missing in
3780 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
3782 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3784 * Makefile.in (c_files): add strerror.c.
3786 * strerror.c: new file from Emacs' sysdep.c.
3787 maybe configure should also check for sys_errlist.
3789 * configure.in (AC_REPLACE_FUNCS): add strerror.
3791 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3793 * debug.c (scm_init_debug): Added initialization for
3794 scm_evaluator_traps.
3796 * debug.h, debug.c: Various name changes.
3797 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
3798 "debug-options-interface". See commentary in options.c.
3800 * options.h, options.c: Options now have documentation strings.
3801 Also added a long explanatory commentary.
3803 * eval.c, print.h, print.c, read.h, read.c: Modifications to
3806 * gscm.c, init.c, root.c, throw.c: Bug fixes:
3807 last_debug_info_frame is now updated in all cases.
3809 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
3812 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3814 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
3815 Added option STACK_CHECKING.
3817 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3819 * Makefile.in: Added {debug,options,srcprop}.{h,c}
3821 * __scm.h: Removed symbols for debugging support.
3823 * acconfig.h: Added symbols for debugging support.
3825 * configure.in: Added user option for debugging support.
3826 --enable-debug will include the debugging code into libguile.a.
3828 * continuations.c (scm_make_cont): Enlarged the #if 0 around
3829 scm_relocate_chunk_to_heap.
3831 * debug.c: New file: low-level debugging support. It also
3832 includes support for debugging with gdb. (The extensions to gdb
3833 are written by Per Bothner at Cygnus.)
3835 * debug.h: New file: low-level debugging support.
3837 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
3838 argument pairs. Extensive modifications to the debugging
3839 evaluator. Added "SECTION:" commentaries to clarify what happens
3840 when, during double compilation. Renamed EVALIMP --> EVALIM.
3841 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
3842 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
3843 the beginning of the file. New procedure: scm_unmemocopy.
3844 Added some global state variables needed by the debugging
3845 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
3846 check_entry, check_apply, check_exit, debug_options and
3847 evaluator_traps. New acro: undefine.
3849 * eval.h: Renamed EVAL --> XEVAL.
3851 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
3852 --> scm_make_weak_key_hash_table.
3854 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
3855 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
3857 * libguile.h: Conditionally include debug.h
3859 * objprop.c (scm_object_properties, scm_set_object_properties_x):
3860 scm_object_properties shouldn't return handle. `handle' now gets
3861 initialized in scm_set_object_properties_x. scm_object_properties
3862 doesn't any longer create an entry in scm_object_whash.
3864 * options.c: New file: handling of run time options.
3866 * options.h: New file: handling of run time options.
3868 * posix.c (scm_getpgrp): Cast pointer to getpgrp.

3889 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3891 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
3893 * libguile.h: #include "objprop.h"; I guess this was forgotten.
3895 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
3896 and should be called by the final client.
3898 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
3900 * gc.h: Use the PROTO macro when declaring functions.
3901 * gc.c: Use the PROTO macro when declaring static functions.
3902 Remove the CPP hair around function definitions.
3904 * gc.c (scm_init_storage): Initialize scm_asyncs.
3906 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
3907 preprocessor symbol; "__scm.h" is where it might get #defined.
3908 * __scm.h: Similar: #include <scmconfig.h> before testing
3911 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
3913 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
3915 * init.c (scm_boot_guile): Add init_func argument; call
3916 (*init_func) instead of calling scm_appinit; it's ucky to
3917 hard-code names for the user's procedures.
3918 * init.h (scm_boot_guile): Adjust declaration.
3920 * __scm.h (PROTO): New macro, for declaring functions with
3923 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
3924 eliminate all the __STDC__ conditionals.
3925 (scm_boot_guile): Add declaration.
3926 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
3927 Remove __STDC__ conditionals around function definitions; the
3928 declarations in init.h will provide the same information, more
3931 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
3932 complain about it in the error message; the error message is
3933 adequate without that note, and there's nothing the user can do
3936 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
3938 * Makefile.in (ancillary): Drop def.sed.
3940 * posix.c (scm_init_posix): Use numeric values, rather than
3941 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
3942 F_OK. The symbols aren't available on some systems, and I'm
3943 pretty sure their values are fixed by common widespread practice.
3944 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
3946 More functions unavailable on some systems.
3947 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
3948 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
3950 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3951 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
3952 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
3953 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
3954 stub that signals an error as the #else.
3956 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
3958 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
3960 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
3962 * unif.c: include ramap.h.

3968 * ports.c: include sys/ioctl.h.
3970 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
3972 * configure.in: check for sys/ioctl.h.
3974 * ports.c: include <malloc.h> not "malloc.h".
3976 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3978 * fports.c: remove ttyname and tmpnam declarations.
3980 * posix.c: fewer ttyname declarations.
3982 * fports.c: include <string.h> not "string.h".
3984 * init.c, ioext.c: include string.h and unistd.h.
3986 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3988 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
3989 genio.c, simpos.c, vports.c: include string.h.
3991 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
3993 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
3995 (scm_addr_buffer_size): change type from scm_sizet to int.
3996 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
3997 from scm_sizet to int.
3999 * error.c: include unistd.h.
4001 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
4004 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
4006 * __scm.hd, def.sed: deleted.
4008 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
4010 Changes for NeXT, suggested by Robert Brown.
4011 * configure.in: Call AC_TYPE_MODE_T.
4012 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
4013 NeXT. Put header file list in alphabetical order.
4014 * configure, scmconfig.h.in: Regenerated.
4015 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
4017 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
4020 * acconfig.h: New file, providing documentation for the CPP
4021 symbols defined in configure.in
4022 * acconfig-1.5.h: Removed; superceded by the above.
4024 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
4026 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
4028 * fports.c (scm_open_file): don't return #f, throw error.
4030 * ioext.c (fileno): renamed from %fileno.
4031 (soft-fileno): deleted.
4033 * ports.c (scm_port_revealed): don't need to check for -1 from
4035 (scm_set_port_revealed_x): return unspecified, not #f.
4037 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
4039 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
4041 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
4043 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
4045 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4047 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
4048 This is necessary on Ultrix, and doesn't hurt portability.
4050 * Makefile.in (dist-dir): New target, implementing a new dist system.
4051 (installed_h_files): Put in alphabetical order.
4052 Remove duplicate entries for markers.h and unif.h.
4053 (c_files): Remove duplicate entries for markers.c.
4054 (ancillary): Renamed from anillery; all uses changed. Remove
4055 PLUGIN; it's a directory, and needs special treatment in dist-dir.
4056 Remove all the ../doc/* files; doc/Makefile.in handles that.
4058 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
4060 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
4061 every if must have an else, or else the whole command has a
4062 non-zero exit code whenever the if's condition is false.
4064 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
4066 * posix.c: include string.h.
4068 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4070 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
4073 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
4074 Remove leading % from scheme names.
4075 Do not return error values, call SCM_SYSERROR or similar.
4077 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
4079 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
4081 * struct.c (scm_init_struct): new file.
4083 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
4085 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
4086 (scm_list_head): added list-head for rapidly chopping argument
4087 lists off of longer lists (and similar).

4091 * objprop.c (scm_object_property): assq the cdr of the whash
4092 handle for obj, not the handle itself.
4094 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
4096 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
4097 weak hash tables last of all marking to avoid an obscure gc bug.
4098 WARNING: circular lists stored in a weak hash table will hose us.
4100 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
4102 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
4103 new functions similar to scm_substring_move_left_x and
4104 scm_substring_move_right_x.
4106 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
4108 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
4111 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
4113 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
4115 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
4117 * strports.c (scm_strprint_obj): convenience function. C for
4118 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
4120 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
4121 removed to a separate library
4123 * init.c (scm_boot_guile): copied from guile-tcl.c.
4124 Initialization specific to tcl interpreters removed.
4126 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
4128 * ports.c (scm_ports_prehistory): size malloced here doesn't
4129 matter so long as it is non-0 (got rid of "* 4").
4131 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
4133 * gscm.h: gscm_mkarray eliminated (presumably was not being used
4134 since its definition was bogus).
4136 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
4138 * mallocs.[ch]: back again (for rx at least).
4140 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
4142 * ports.c: removed functions relating to the mapping between ports
4143 and descriptors. (That stuff is unix-specific and should be collected
4144 in a separate library).
4146 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
4147 (Tom Mckay@avanticorp.com)
4149 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
4151 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
4152 handled correctly (SCM_FREEP was applied to them) -- test for
4153 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
4154 being overwritten with #f. (brown@grettir.bibliotech.com)
4156 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>

4186 NOTE: don't use a alist here.
4187 (scm_set_procedure_properties_x): fix type checking throughout this file.
4189 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
4191 * ports.c (scm_remove_from_port_table): adjust scm_mallocated

4197 * vports.c (scm_make_soft_port): allocate a port table entry
4198 (possibly triggering gc) before setting the tag of the corresponding
4201 * pairs.c (scm_delq_x): never throw an error.
4203 * vectors.c (scm_make_vector): made the default vector fill argument
4204 into '() (much more useful than the previous value, "#unspecified")
4206 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
4208 * ports.c (scm_add_to_port_table): Added fields
4209 to port table entries: file_name, line_num, col.
4210 Update these in open_file, gen_getc and gen_ungetc.
4211 Added procedures to access those fields.
4213 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
4215 * procs.c (scm_make_subr_opt): new entry point for making
4218 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
4220 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
4222 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
4224 * numbers.c (scm_exact_p): This function no longer
4225 implements "integer?".
4227 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
4229 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
4230 (scm_gc_stats): return an assoc of useful data. Replaces "room"
4231 and the stats reporting formerlly built into repl.
4233 * repl.[ch]: removed.
4234 GC statistics keeping moved to gc.c.
4235 Other statistics keeping can be done from Scheme.
4236 REPLS are now written in Scheme.

4243 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
4245 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
4247 * feature.c (scm_compiled_library_path): moved here from repl.c.
4248 This file is for stuff relating specifically to Scheme libraries
4251 * eval.c (scm_m_define): don't give warning about redefinition, don't
4254 NOTE: this should throw a resumable exception with parameters --
4255 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
4257 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.

4279 because it changes size.
4281 (stputc stwrite): check/change the strings length with interrupts
4284 * objprop.c (scm_set_object_property_x &c): use the generic
4285 hashing functions and be threadsafe.

4288 (per suggestion jaffer@gnu.ai.mit.edu).
4290 * mbstrings.c (scm_multi_byte_string): guard against argument list
4293 * strings.c (scm_make_string): loop cleanup

4321 initialization to fix a race condition.
4323 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

4325 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
4327 * throw.c (_scm_throw): Pass throwval on the stack, not in a global
4328 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
4330 * *.[ch]: namespace cleanup. Changed all (nearly) exported CPP
4331 and C symbols to begin with SCM_ or scm_.

4347 set the multi_byte flag correctly in symbols. This is wrong.
4348 intern_obbary_soft and msymbolize should take an extra parameter.
4349 Also, weird multibyte symbols don't print correctly.
4350 The weird symbol syntax is also a bit bogus (emacs doesn't quite
