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

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

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

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

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

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

286 have to do this explicitly. Also, if regexp/basic is supplied, then
287 turn off REG_EXTENDED.
288 (scm_init_regex_posix): New regexp/basic symbol.
289 (REG_BASIC): #define this if it is not already present.

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

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

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

384 * ports.h: new prototype.
385 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.

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

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

461 supplied. (Change from Tim Pierce.)
463 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
465 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
466 23:47:01 1997" changelog: Slots are now initialized with `#f' by
467 default and not `()'. `#f' is the canonical non-value in Scheme,
470 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
472 * struct.c (struct_printer): New variable that holds a handle on
473 the Scheme variable *struct-printer*. This variable can be set by
474 Scheme code to override the printing of structures.
475 (scm_print_struct): If struct_printer is set, call it. If it is
476 not set, or returns #f, print the structure in the old fashion.
477 Include "eval.h" for scm_apply.
479 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
481 * struct.c (scm_struct_ref, scm_struct_set_x): Use

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

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

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

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

729 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
730 (scm_display_error_message): use RO macros when strings may be RO.
731 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
732 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
733 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

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

972 when PROC is receiving no arguments.
974 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
976 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
977 have S_IFSOCK. This is the case under Ultrix.
979 * posix.c (scm_status_exit_val, scm_status_exit_val,
980 scm_status_term_sig, scm_status_stop_sig): Modified to work with
981 Ultrix versions of WIFSTOPPED, etc., which assume that their
982 arguments are lvalues (hmm).
984 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
988 * throw.c: Doc fixes; rearranged.
990 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
992 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
994 * acconfig.h: Added entry for PACKAGE.
995 * scmconfig.h.in: Regenerated.
997 Changes to work with automake-1.1n, which has better libtool support.
998 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
999 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
1001 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
1003 * Makefile.in: Rebuild.
1005 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1007 * stime.c (scm_mktime): take an optional zone argument.
1008 (scm_localtime): check putenv return value.
1009 (scm_strftime, scm_strptime): moved from posix.c. move #include

1012 (bdtime2c, setzone, restorezone): new static procedures.
1013 (scm_mktime, scm_strftime): use them.
1014 (scm_strftime): don't call mktime before strftime. Use
1015 filltime for return value.
1016 (filltime): convert NULL zname to #f.
1017 (scm_strptime): return a count of characters consumed, not
1018 the remaining string.
1020 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1022 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
1023 (scm_mktime): likewise.
1025 Uncomment localtime and mktime.
1027 * configure.in: add AC_STRUCT_TIMEZONE.
1029 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
1031 * stime.c (scm_init_stime): don't define ticks/sec.
1032 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
1033 return value problem and is still portable.)
1035 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
1037 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
1038 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
1039 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
1040 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
1041 cpp_err_symbols.c): Corresponding changes.
1042 * Makefile.in: Regenerated.
1044 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
1046 * posix.c (scm_putenv): don't check HAVE_PUTENV.
1047 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
1048 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
1049 * putenv.c: new file, from sh-utils 1.12.
1051 * posix.c (scm_environ): use malloc in place of scm_must_malloc
1052 since allocation isn't for Scheme objects.
1053 (scm_putenv): copy strings before placing in the environment.
1055 * stime.c (scm_current_time): throw an error if time returns -1,
1056 instead of returning #f.
1057 (scm_get_internal_real_time, scm_get_internal_real_time): use
1058 scm_long2num for return value instead of SCM_MAKINUM.
1060 * stime.h: prototypes updated.
1062 * stime.c (scm_time_in_msec): apparently unused, deleted.
1064 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
1066 * configure.in: check for gettimeofday.
1068 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
1069 which may be more usefully portable than a gettimeofday interface.
1071 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
1073 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
1075 * Makefile.in: Regenerated.
1077 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
1079 * stime.c (filltime): recovered static procedure.
1080 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
1083 * posix.h: add prototype for scm_close_pipe, remove prototypes for
1084 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
1086 * posix.c (scm_mknod): split the mode argument into type and perms
1087 arguments, like the extra fields returned by stat.
1089 * fports.c (scm_pipob): set the close, free and print procedures.
1090 (scm_close_pipe): new procedure.
1092 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
1093 define them in boot-9.scm
1095 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1097 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
1098 wan't defined. Don't include fd.h.
1100 * Previously fd.h was regenerated whenever configure was run,
1101 forcing a couple of files to be recompiled.
1103 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
1104 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
1105 Check for _fileno as well as _file.
1107 * ioext.c: don't fd.h.
1108 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
1111 * Change the stratigy for getting information about errno
1112 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
1113 generating lists of symbols during the build process, which will
1114 not always work, include comprehensive lists in the distribution.
1115 To help keep the lists up to date, the "check_signals" and
1116 "check_errnos" make targets can be used.
1118 * configure.in: don't check for a command to extract errno codes.
1119 * Makefile.am: update file lists, remove errnos.list and errnos.c
1120 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
1121 check_errnos targets.
1122 (CLEANFILES): remove errnos.c and errnos.list, add
1123 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
1124 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
1125 * errnos.default: deleted.
1126 * cpp_signal.c: new file.
1127 * cpp_errno.c: renamed from errnos_get.c.
1128 * cpp_err_symbols, cpp_sig_symbols: new files.
1129 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
1130 * error.c (scm_init_error): #include cpp_err_symbols instead of
1132 * posix.c (scm_init_posix): don't intern signal symbols. #include
1135 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
1137 * strop.c (scm_i_index): allow the lower bound to be equal to the
1138 length of the string, so a null string doesn't always give an error.
1140 * posix.h: new prototypes.
1141 * posix.c (scm_status_exit_val, scm_status_term_sig,
1142 scm_status_stop_sig): new functions, as in scsh. They break down
1143 process status values as returned by waitpid.
1145 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
1147 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
1148 configure doesn't know about it.
1150 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1152 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
1154 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
1155 which defines C variables with global linkage.
1157 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1159 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
1162 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
1164 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
1165 has time to check why this doesn't work well with continuations.
1167 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
1169 * Fix shell syntax error; some shells won't tolerate
1170 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
1172 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
1174 * posix.c (scm_uname): throw an error if uname fails instead
1177 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
1179 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
1182 * async.c (scm_ints_disabled): definition moved from error.c.
1184 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1186 * acconfig.h: Removed PACKAGE.
1188 * scmconfig.h.in: Regenerated.
1190 * snarf.h: g++ says it's non-portable not to specify the first
1191 argument in a varargs declaration. I introduced the first
1192 argument by using preprocessor conditionals.
1194 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
1196 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
1197 (scm_freopen): use RO string macros for filename and modes.
1198 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
1200 * posix.c (scm_getgrgid): simplify conversion of name to C string.
1201 (scm_mknod): use RO string macros for path.
1203 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
1204 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
1206 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
1207 use SCM_ROSTRINGP and SCM_ROCHARS.
1209 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1211 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
1214 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
1215 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
1216 support for byte vectors.
1218 * print.c (scm_iprin1): Limit number of vector elements printed
1219 according to pstate->length.
1221 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
1223 * backtrace.c (scm_display_error_message): don't segv if message
1226 * error.h: prototype for scm_error_scm.
1228 * error.c (scm_error_scm): new procedure, reimplements scm-error
1229 in C and uses scm_error.
1231 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
1233 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
1234 pointer to the Scheme variable read-hash-procedures and intern it
1235 in scm_init_read. Modify scm_read_hash_extend and
1236 scm_get_hash_procedure to use the pointer.
1238 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1240 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
1241 (SCM_KEYWORD_STYLE): defined.
1243 * read.c (scm_read_opts): add a keywords option. This isn't a
1244 boolean option, in case someone wants to add support for DSSSL
1246 Setup scm_keyword_prefix symbol.
1247 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
1249 I've left keyword support disabled by default, since it doesn't
1250 seem to break the module system and it gives R4RS standard behaviour.
1251 It can be reactivated with (read-set! keywords 'prefix).
1253 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1255 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
1256 before constructing arbiter.
1258 * eval.c (scm_m_define): Bugfix: Check that the object is a
1259 closure before setting the procedure property!
1261 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
1263 * ports.c: Removed `ungetc-char-ready?'.
1265 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
1267 * read.c (scm_init_read): intitialise scm_read_hash_procedures
1268 (idea from Mikael: make it a pair so scm_permanent object only
1270 (scm_read_hash_extend): don't call scm_permanent_object.
1271 (ideas from Mikael): if chr is already in the list, replace its
1272 procedure instead of appending it again. If proc is #f, remove
1274 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
1276 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
1278 * gdbint.c (gdb_read): update scm_lreadr usage.
1280 * load.h: update prototypes.
1282 * load.c (scm_primitive_load, scm_read_and_eval_x,
1283 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
1285 * read.h: add prototype for scm_read_hash_extend. Change args for
1288 * read.c (scm_read_hash_procedures): new variable.
1289 (scm_read_hash_extend): new procedure.
1290 (scm_get_hash_procedure): new procedure.
1291 (scm_lreadr): use scm_get_hash_procedure instead of an argument
1292 for extended # processing.
1293 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
1294 scm_read_token): remove case_i, sharp arguments. Change callers.
1296 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
1298 * read.h (SCM_N_READ_OPTIONS): increase to 3.
1299 (SCM_CASE_INSENSITIVE_P): define.
1301 * read.c: add case-insensitive option to scm_read_opts.
1302 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
1303 to determine whether to convert symbol case.
1304 (default_case_i): definition removed.
1305 * read.c (scm_read_token): if case_i, downcase ic before doing
1308 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1310 * configure.in: Added configuration option `guile-debug'.
1311 Configure with --enable-guile-debug if you want a bunch of extra
1312 functions used for debugging when developing Guile.
1314 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
1316 * procs.c (make-cclo): New undocumented debugging procedure: Make
1317 compiled closure with internal procedure PROC and length LENGTH.
1318 Only compiled if GUILE_DEBUG is defined.
1320 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
1322 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
1324 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
1326 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
1327 with 3 or more args internally to the evaluator.
1329 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1331 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
1332 with 3 or more args internally to the evaluator. This is mainly
1333 because we don't want to pass entry and exit points of the
1334 debug support twice, but it also seems to increase the speed of
1335 the evaluator for such calls (e. g. (+ 1 2 3)).
1337 * backtrace.c (scm_display_application): New procedure:
1338 display-application; Set fancy printing parameters individually
1339 for different types of display (backtrace, error, application).
1340 (These should of course be customizable!)
1342 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
1343 clear the CHECK-flags.
1345 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1347 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
1349 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1351 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
1352 from pairs with a GLOC in the car.
1354 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
1355 otherwise `symbol-hash' will behave badly.
1356 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
1357 we get segmentation fault!
1359 * symbols.c: Added #include "weaks.h". New functions:
1360 `builtin-bindings' and `builtin-weak-bindings'. (These will be
1361 moved to an extraneous library when we split libguile.)
1363 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1365 * filesys.c (scm_stat): stat now takes fport arguments too as
1366 documented in the manual.
1368 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1370 * debug.c (scm_single_step): Bugfix: Call continuation with
1371 scm_call_continuation instead of throwing to it.
1373 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1375 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
1376 argument wasn't declared to be optional.
1378 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1380 * stime.c (scm_init_stime): Add feature "current-time".
1382 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
1384 * throw.h: prototype for scm_exit_status.
1385 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
1386 args to derive an exit status. Allows (quit) to work from a
1388 (scm_exit_status): new function.
1391 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1393 * eval.c (scm_deval): Removed some old code.
1394 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
1396 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
1399 * symbols.c (msymbolize): Bugfix: Must initialize property list to
1402 * procs.c: Introduce the existent C function scm_thunk_p at the
1403 Scheme level as well.
1405 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1407 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
1408 used from C to easily lookup the value of a symbol in the current
1411 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1413 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
1414 scm_init_unif in this file. This will also fix a previous problem
1417 * configure.in: Added AM_MAINTAINER_MODE
1419 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1421 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
1424 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1426 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
1427 source files that are not always included in libguile but should
1428 have their dependencies calculated by automake. This variable is
1429 recognized by automake, no further magic is needed.
1430 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
1431 to deal exclusively with *.lo files, as it seems. The *.o files
1432 are built automatically when the corresponding *.lo file gets
1435 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
1437 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
1440 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
1442 * unif.c (scm_array_set_x): minor change to argument error checking.
1444 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
1446 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
1447 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
1448 They should only be included in the library at configure.in's
1450 (libguile_la_LDADD): Include the appropriate .lo files here.
1451 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
1452 so we know when to build them (and their .lo bretheren).
1453 * configure.in (LIBLOBJS): New substituted variable. We let
1454 configure decide which .o files to include in LIBOBJS, and then
1455 put the corresponding list of .lo files in LIBLOBJS. The latter
1456 is what we pass to libtool.
1457 * Makefile.in, configure: regenerated.
1459 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
1461 * symbols.c (scm_sysintern0): New function. Contains the core of
1462 old scm_sysintern but doesn't take a second value argument.
1463 (scm_sysintern): Now uses scm_sysintern0.
1464 (scm_sysintern_no_module_lookup): Renamed to
1465 scm_sysintern0_no_module_lookup and doesn't take a second value
1466 argument any longer.
1468 * symbols.h (scm_sysintern0: Added declaration.
1470 * options.c (scm_init_opts): Use scm_sysintern0 instead of
1471 scm_sysintern when interning option keys. Otherwise we risk
1472 destroying the values of already interned variables.
1474 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
1475 scheme-level boolean (use SCM_NFALSEP).
1477 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
1479 (scm_backtrace): New function. (C version of old function from
1480 boot-9.scm) Motivation: Make it possible to display backtraces
1481 without depending on boot-9.scm. (I'm uncertain if this
1482 motivation is good enough...)
1484 * root.h (scm_root_state): Add member the_last_stack_var.
1485 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
1487 * root.c (mark_root): Mark scm_the_last_stack_var.
1489 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
1492 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
1494 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
1495 1. mark_lazy_catch didn't mark the smob.
1496 2. Both functions above have standard variants:
1497 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
1498 free_lazy_catch --> scm_free0.
1500 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
1502 * throw.c (scm_internal_lazy_catch): New function.
1503 (scm_lazy_catch): Rewritten to use it.
1504 (scm_ithrow): Handle the new lazy catch representation.
1505 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
1506 that doesn't have a jmpbuf is a lazy catch clause.
1507 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
1508 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
1509 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
1511 (scm_init_throw): Register the new lazy-catch smob type.
1512 * throw.h (scm_internal_lazy_catch): decl for new function.
1514 * throw.c (scm_internal_catch): Doc fixes.
1516 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
1517 configure.in. Including this might cause problems if applications
1518 that link against libguile include their own copies of alloca, but
1519 if they're using autoconf, they should be adding libguile to LIBS
1520 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
1521 the copy in libguile, and things will be okay. (I think.)
1523 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1525 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
1527 strop.h: move prototypes too.
1529 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
1531 * posix.c (scm_init_posix): don't intern EINTR since it's now done
1534 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
1535 etc. I deleted them from filesys.c long ago, but didn't
1536 notice they were here too (although ineffective since
1537 sys/stat.h wasn't included).
1539 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
1541 * eval.c: Don't define alloca in GCC case. gcc will automatically
1542 use __builtin_alloca if appropriate.
1544 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
1546 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
1547 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
1548 that values of automatic variables are preserved. See comments
1549 for safe_setjmp for details.
1551 Change from Thomas Morgan:
1552 * variable.c: Include eq.h.
1553 (var_equal): New function.
1554 (variable_smob): Use var_equal as the discriminator for variables.
1556 * throw.c (s_throw): Remove extraneous declaration.
1558 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
1559 * eval.c: Add necessary CPP cruft to support that.
1560 * configure, Makefile.in, scmconfig.h.in: regenerated.
1562 Change from Thomas Morgan:
1563 * procprop.c (scm_procedure_properties): Convert the Scheme
1564 boolean returned by scm_procedure_p into a C boolean before using
1565 it as a condition for SCM_ASSERT.
1566 (scm_procedure_property): Likewise.
1568 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
1569 indications of Unixness.
1572 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
1574 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
1576 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
1578 * read.c (scm_lreadr): use scm_misc_error to improve one of the
1579 "unknown # object" error messages.
1581 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
1582 (scm_i_index) and declare it static. Add a 'direction' argument
1583 to indicate what way the search should go.
1584 (scm_i_index): throw out-of-range error instead of wrong-type-arg
1586 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
1587 strop.h: remove scm_i_index, scm_i_rindex prototypes.
1589 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1591 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
1593 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
1594 to avoid clash with various scsh forks.
1596 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
1598 The following two changes (ramap.c, throw.c) are motivated by the
1599 apparent unportability of forward declarations of static arrays of
1600 the form `static foo bar[];'.
1602 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
1603 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
1605 * throw.c (scm_throw): Moved above scm_ithrow.
1607 * options.h: Removed the extern declarations of scm_yes_sym and
1608 scm_no_sym since these are static.
1610 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1612 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
1614 * Makefile.am: remove AWK=@AWK@.
1615 Add a rule for generating errnos.list.
1616 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
1618 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
1619 don't extract errnos, just set a variable (avoids the
1620 need to recompile error.c just because configure is run.)
1622 * unif.h: update prototypes.
1623 * unif.c (scm_uniform_array_read,write): change the offset and
1624 length arguments to start and end, for consistency.
1626 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
1628 * ioext.h: update prototypes.
1629 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
1630 scm_read_line_x, it's a more general procedure using an
1631 interface from scsh. read-line and read-line! are now defined
1633 Note that the new read-line trims the terminator
1634 by default, previously it was appended to the returned string. An
1635 optional argument specifies how to process the terminator (scsh
1636 compatible). For the old behaviour: (read-line port 'concat).
1637 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
1638 returns a pair, but is converted to multiple values if the scsh
1641 socket.h: update prototypes.
1642 * socket.c (scm_recvfrom): for consistency with other procedures,
1643 take start and end as separate optional arguments.
1644 (scm_recv, scm_recvfrom): don't allow the second argument
1645 to be a size, only a buffer. Change the scheme names to
1646 recv! and recvfrom!. Don't return the buffer.
1648 * ioext.h, posix.h: move prototypes too.
1649 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
1650 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
1651 "read.h" and "unif.h".
1652 * ioext.c: include "chars.h"
1654 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
1656 * dynl.c: The dynamic linking and module registration functions
1657 are now defined even when dynamic linking is not available for the
1658 host system. Some of their functionality can be done without
1659 dynamic linking; when it's really needed, they throw errors.
1661 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
1663 * configure.in: Only define DYNAMIC_LINKING when one of the system
1664 dependent functions is detected.
1665 * dynl.c (scm_dynamic_func): New function to get the address of a
1666 function in a dynamic object.
1667 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
1668 produced by scm_dynamic_func as the thing to call.
1670 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
1672 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
1673 (scm_register_module_xxx, scm_registered_modules,
1674 scm_clear_registered_modules): New functions.
1676 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
1678 * symbols.c (scm_sysintern): Renamed to
1679 scm_sysintern_no_module_lookup.
1680 (scm_sysintern): New function to take the place of the old
1681 scm_sysintern. It uses the current toplevel lookup closure to give
1682 the symbol its value. This is a temporary hack to put packages
1683 like gtcltk into their own module.
1684 (scm_can_use_top_level_lookup_closure_var): New variable to tell
1685 us whether `scm_top_level_lookup_closure_var' has been initialized
1687 * eval.c (scm_init_eval): Set it.
1689 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
1691 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
1692 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
1694 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
1696 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
1697 scm_sys_dup): deleted: FD capability will be added to other
1699 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
1700 scm_fd_free, fd_smob, scm_intern_fd.
1701 (scm_open): renamed from scm_sys_open. Return a port instead of
1702 an FD object. Make the mode argument optional.
1703 (scm_sys_create): deleted, it's just a special case of open.
1704 (scm_init_filesys): move interning of constants O_CREAT etc.,
1705 here (were previously using SCM_CONST_LONG macro).
1706 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
1708 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
1709 include "fports.h" and <stdio.h>
1710 (scm_stat, scm_select): don't support FD objects.
1712 * error.h: adjust scm_syserror_msg prototype.
1713 * error.c (scm_syserror_msg): take an extra argument for errno.
1714 Using the global value didn't always work, since it could be
1715 reset by procedure calls in the message or args arguments.
1717 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
1718 I don't understand why the check was there (and what about the
1721 * strop.c (scm_string_copy): allow shared substrings to be copied.
1723 * unif.h: corresponding change to prototypes.
1724 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
1725 recognize two new optional arguments: offset and length. Allow
1726 the port argument to be an integer (file descriptor, for scsh).
1727 Include <unistd.h> for "read" prototype.
1729 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
1731 * socket.c: don't include filesys.h.
1733 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
1735 * Makefile.am: add AWK=@AWK@ (?)
1737 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
1739 Add a rule to generate errnos.c from errnos.
1740 * error.c (scm_init_error): include errnos.c.
1741 * errnos_cnvt.awk: new file, converts the list of errno codes to
1743 * errnos_get.c: new file.
1744 * errnos.default: new file, contains errnos to try if they can't
1745 be extracted from errno.h.
1746 * configure.in: if using GCC, try and extract errno codes from
1750 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
1752 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
1753 * Makefile.am: Made libguile into a libtool library.
1754 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
1755 Set libtool_libs to indicate that libguile is a libtool library.
1756 See guile/ChangeLog for details.
1757 * .cvsignore: ignore "*.lo", the libtool library objects.
1759 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1761 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
1762 use htons in getservbyport argument.
1764 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
1766 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
1767 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
1770 * objprop.c (scm_object_property): No need to take the CDR of the
1771 value returned by scm_object_properties, since Aug 20 change.
1773 * configure.in: When checking for struct linger, #include
1774 <sys/types.h> as well as <sys/socket.h>. I've never known
1775 <sys/types.h> to cause any portability problems, and Solaris's
1776 <sys/socket.h> needs it.
1777 * configure: Rebuilt.
1779 I think the Sun compiler has chosen a perverse way to interpret
1780 ANSI declarations combined with K&R definitions. We'll
1781 appease it a little bit. But when it invades France, we fight.
1782 * print.c (scm_iprlist): Change 'tlr' argument to an int.
1783 * print.h (scm_iprlist): Here too.
1784 * numbers.c (scm_divbigdig): Change definition to match
1785 declaration in numbers.h.
1786 * unif.c (scm_makflo): Change definition to match declaration in
1789 * init.c (scm_boot_guile): Don't return the value of
1790 scm_boot_guile_1. This function doesn't return a value;
1791 scm_boot_guile_1 doesn't return a value (or return at all).
1793 * eval.c (unmemocopy): Add a semicolon to appease the Sun
1796 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
1797 compile. I have a feeling this function is a bad idea anyway ---
1798 one should always test for features, not systems.
1800 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
1801 semicolons. Only pure luck kept this from being noticed earlier.
1803 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
1805 * socket.c (scm_recvfrom): Added missing semicolon.
1807 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1809 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
1810 the buffer and start and end positions for scsh networking
1813 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
1815 * configure.in: Revert previous change to this file; the problem
1816 is due to transient automake weirdness.
1817 * configure: Rebuilt.
1819 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
1820 PLUGIN/guile.libs. configure generates the latter from the former.
1821 * Makefile.in: Rebuilt.
1823 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
1824 need this if we install scripts, like guile-snarf.
1825 * configure: Rebuilt.
1827 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1829 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
1831 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
1833 * socket.c (scm_addr_vector): fix faulty scm_listify.
1835 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
1837 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
1838 style block comment is no longer considered an error.
1840 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
1842 * PLUGIN/guile.libs.in: New file.
1843 * PLUGIN/guile.libs: Removed from repository.
1844 * configure.in: Create PLUGIN/guile.libs from
1845 PLUGIN/guile.libs.in. This is for including additonal libraries
1846 needed for dynamic linking.
1847 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
1848 instead of PLUGIN/guile.libs.
1850 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
1852 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
1854 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
1855 occurrences of the given element from the list, not just the
1856 first. This is how the Emacs Lisp functions behave, how the
1857 analogous Common Lisp functions behave, and (I believe) how the
1858 older Maclisp functions worked. I realize that this change may
1859 break code, but it seemed better to break it before the Guile
1862 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
1863 Their prototypes were already present in gc.h, but they weren't
1865 (scm_init_storage): Initialize scm_protects.
1866 * root.c (scm_protects): New element of scm_sys_protects.
1868 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
1870 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1872 * libguile.h: Added #include "libguile/net_db.h".
1874 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
1875 30 change. That file is only meant for communication between the
1876 configuration process and load.c. If code linked against libguile
1877 wants to get at the paths mentioned in libpath.h, it can call
1878 functions declared in load.h.
1880 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1882 * libguile.h: Removed #include "libguile/fdsocket.h"
1884 * net_db.c: Added #include <sys/socket.h>.
1886 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
1888 * filesys.c (scm_input_waiting_p): use select in preference to
1889 FIONREAD, since the latter doesn't detect EOF.
1890 Throw error if neither select nor FIONREAD available.
1892 * socket.c (scm_connect): take a port, not a fd object.
1893 (scm_fill_sockaddr): throw an error if fam is not recognised.
1894 (scm_bind): use scm_fill_sockaddr.
1895 (scm_listen): take a port, not a fd object.
1896 (scm_accept): take and return a port. return #f in the car if
1897 address can't be got
1898 (scm_sock_fd_to_port): new procedure.
1899 (scm_socket): use scm_sock_fd_to_port.
1900 (scm_addr_vector): throw error if unrecognised address type.
1901 take an extra argument with the calling procedure name.
1902 (scm_getsockname): take a port. return #f if address can't be got.
1903 (scm_getpeername): take a port. return #f if address can't be got.
1904 (scm_recvfrom): take a port. return #f for address component if can't
1906 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
1907 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
1909 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
1911 * throw.c (scm_internal_catch): Make body funcs and handler funcs
1912 use separate data pointers, to allow them to be designed
1913 independently and reused.
1914 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
1915 Renamed from catch_body, catch_handler, and uncaught_throw; made
1917 (struct scm_catch_body_data): Renamed from catch_body_data; moved
1919 (scm_catch): Use the above.
1920 (scm_throw): Don't bother printing a message for an uncaught
1921 throw; we establish a default handler in init.
1922 * throw.h (scm_internal_catch): Prototype updated.
1923 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
1925 (struct scm_body_thunk_data): New structure, used as data
1926 argument to scm_body_thunk.
1927 * init.c (struct main_func_closure): New structure, packaging up
1928 the data to pass to the user's main function.
1929 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
1930 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
1931 scm_internal_catch to establish a catch-all handler, using
1932 scm_handle_by_message. This replaces the special-case code in
1934 (invoke_main_func): Body function for scm_internal_catch; invoke
1935 the user's main function, using the main_func_closure pointer to
1936 decide what to pass it.
1937 * root.c (struct cwdr_body_data): Remove handler_proc member.
1938 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
1939 (cwdr_handler): Removed.
1941 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1943 * socket.h (SCM_P): update bind prototype.
1944 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
1945 include "feature.h".
1946 (scm_socket): return a port, not a file descriptor object.
1947 include "fports.h" and <unistd.h>
1948 (scm_bind): take a port, not a file descriptor object.
1949 take an extra argument for address args.
1951 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
1952 INADDR_NONE, INADDR_LOOPBACK.
1954 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1956 * init.c: include net_db.h and not fdsocket.h.
1957 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
1959 * Makefile.am: corresponding changes.
1960 * socket.h: renamed from fdsocket.h, fix names.
1961 * net_db.h: renamed from socket.h, fix names.
1962 * socket.c: renamed from fdsocket.c.
1963 remove _sys from procedure names.
1964 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
1965 add "socket" to features list.
1966 * net_db.c: renamed from socket.c.
1967 remove _sys from procedure names.
1968 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
1969 add "net-db" to features list.
1970 include "net_db.h". don't include <sys/socket.h> or
1973 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1975 * tags.h (scm_tags): Removed comma at end of last enumerator.
1977 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
1979 Don't use GCC extensions to allocate space for debugging frames.
1980 (Here he goes again! Why do we put up with this?!)
1981 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
1982 an scm_debug_info structure, not an in-line array of them. Add
1983 'info' member, to say how many vect elements we've used, for eval
1985 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
1986 a new variable debug_info_end to mark the end of vect, instead of
1987 the address of the 'info' pointer itself.
1988 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
1989 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
1990 (SCM_APPLY): Explicitly allocate space for debug.vect.
1991 * debug.c (scm_m_start_stack): Same, for vframe.vect.
1992 * stacks.c: Adjusted for new debug frame structure.
1993 (RELOC_INFO, RELOC_FRAME): New macros.
1994 (stack_depth, read_frames): Use them, and new scm_debug_frame
1995 element 'info', instead of magically knowing that eval frames have
1996 an info pointer sitting after vect.
1997 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
1999 (scm_init_stacks): Formatting tweaks.
2001 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
2003 Give GCC more control flow information, so it can be sure that
2004 variables aren't used uninitialized.
2005 * error.h (scm_error, scm_syserror, scm_syserror_msg,
2006 scm_sysmissing, scm_num_overflow, scm_out_of_range,
2007 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
2008 scm_misc_error): Tell GCC that these functions never return.
2009 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
2010 out the field type, call abort if SCM_ASSERT returns, to placate
2012 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
2013 scm_wta ever returns. We can't handle this case anyway, and this
2014 gives the optimizer more information.
2015 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
2016 scm_wta ever returns.
2018 In some cases, the code is fine, but GCC isn't smart enough to
2019 figure that out; this usually happens when one variable is only
2020 initialized and used when a particular condition holds true, and
2021 we know that condition will never change within a given invocation
2022 of the function. In this case, we simply initialize the variables
2023 to placate the compiler, hopefully to a value which will cause a
2024 crash if it is ever actually used.
2025 * print.c (scm_iprin1): Initialize mw_pos.
2026 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
2027 * throw.c (scm_ithrow): Initialize dynpair.
2028 * unif.c (scm_uniform_vector_ref): Initialize cra.
2029 * struct.c (init_struct): Initialize prot.
2030 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
2032 * strports.c (scm_eval_0str): Don't return uninitialized garbage
2033 if EXPR contains no expressions.
2035 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2037 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
2038 cause an infinite loop (???). So much for the algebraic
2039 equivalency of variable-sized arrays and alloca...
2041 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
2043 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
2044 a SCM boolean, not a C boolean.
2046 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
2048 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
2049 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
2050 rules for raising scm_mtrigger. Previously, unfortunate but not
2051 unlikely circumstances could result in almost constant invokation
2052 of the gc. Now, this situations should be less likely, but they
2053 are not prevented completely.
2055 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
2057 * numbers.c (scm_fuck): Procedure removed; looks like old test
2059 * numbers.h: Prototype removed.
2061 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
2063 * debug.h (scm_debug_frame): Change `vect' member from an in-line
2064 array to a pointer, to match my Nov 21 change in eval.c.
2066 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2068 * libguile.h: Added #include "libguile/backtrace.h", #include
2069 "libguile/stacks.h".
2071 * strings.c (scm_string scm_make_string scm_string_ref
2072 scm_string_set_x scm_string_equal_p scm_string_append):
2073 Bugfix according to scm patch from Aubrey Jaffer:
2074 Corrected long-standing
2075 (not (eqv? (integer->char 128)
2076 (string-ref (make-string 1 (integer->char 128)) 0)))
2077 bug found by John Kozak <jk@noontide.demon.co.uk>.
2079 * strports.c, strports.h: Make scm_eval_0str return the value of
2080 the last expression evaluated (previously, it returned void).
2082 * strports.c, strports.h: New function: scm_read_0str. Does what
2085 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2087 * simpos.c (scm_getenv): return #f if string can't be found in the
2088 environment instead of throwing an exception, for compatibility
2089 with numerous other systems.
2091 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
2093 * Makefile.am (.c.x): Use guile-snarf.
2094 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
2096 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
2098 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
2100 * backtrace.c (scm_display_error_message): Made non-static, and
2101 renamed from display_error_message.
2102 * backtrace.h (scm_display_error_message): Added extern decl.
2103 * throw.c (uncaught_throw): Use it to display the error message.
2105 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
2107 * inet_aton.c: Use #if 0, not #ifdef 0.
2109 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
2111 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
2112 to convert the returned value.
2113 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
2114 the offset argument.
2116 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
2118 Add new interface to catch/throw, usable from C as well as
2120 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
2121 (scm_internal_catch): New function, replaces...
2122 (scm_catch_apply): Deleted.
2123 * throw.c (scm_catch_apply): Deleted; replaced with a more general
2124 mechanism which is a bit more code, but can be used nicely from C
2125 and implement the Scheme semantics as well.
2126 (scm_internal_catch): This is the replacement; it's named after
2127 the analogous function in Emacs.
2128 (scm_catch): Reimplemented in terms of the above.
2129 (struct catch_body_data, catch_body, catch_handler): New
2130 functions, used by scm_catch.
2131 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
2132 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
2133 support for new cwdr.
2135 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
2138 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
2140 * acconfig.h: Added DYNAMIC_LINKING symbol.
2141 * configure.in: Add option and checks for dynamic linking.
2142 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
2143 dynl.h: New files for dynamic linking support.
2144 * Makefile.am (libguile_a_SOURCES):
2146 (modinclude_HEADERS): Added "dynl.h".
2147 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
2149 * init.c (scm_boot_guile_1): Call
2150 scm_init_dynamic_linking to initialize dynamic linking support.
2152 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
2154 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
2155 (as we Schemers say). It needs to be global, so that I can tweak
2156 it for the proper operation of unexec.
2157 (scm_boot_guile_1_live): New variable, see above.
2159 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
2161 * guile-snarf.sh: Removed.
2162 * PLUGIN/guile.libs: Added dependency for -lm.
2163 * acinclude.m4: Renamed from aclocal.m4.
2164 * PLUGIN/greet: Removed.
2165 * Makefile.am, aclocal.m4: New files.
2166 * configure.in: Updated for Automake.
2168 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
2170 * eval.c (scm_definedp): Use top_level_lookup_closure_var
2171 and not top_level_lookup_thunk_var.
2173 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
2175 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
2177 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
2179 * eval.c (scm_definedp): Incompatibly changed to be a builtin
2180 Scheme function, instead of syntax. Single argument is now a
2183 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2185 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
2186 scm_ra_divide): Properly terminate statements passed as arguments
2187 to IVDEP macros. (Thanks to Bernard Urban.)
2189 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
2190 with non-constant sizes. (Thanks to Bernard Urban.)
2192 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
2194 It's an "eval closure", not an "eval thunk." A thunk is a
2195 function of no arguments.
2196 * root.h (struct scm_root_state): Renamed
2197 top_level_lookup_closure_var from top_level_lookup_thunk_var.
2198 (scm_top_level_lookup_closure_var): Renamed from
2199 scm_top_level_lookup_thunk_var.
2200 * root.c (mark_root): Uses changed.
2201 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
2202 * init.c (scm_start_stack): Uses changed.
2203 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
2204 Change scheme-visible name to *top-level-lookup-closure* from
2205 *top-level-lookup-thunk*.
2207 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
2209 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
2210 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
2212 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
2214 * gc.c (struct scm_heap_seg_data): Doc fixes.
2216 * gc.c (scm_gc_sweep): Empty all segments' freelists before
2217 sweeping. Then, prepend each segment's free cells to its
2218 freelist, rather than wiping out the old value. (Thanks to Marius
2221 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
2222 scm_check_freelist, scm_debug_newcell): New functions and
2223 variables, for debugging freelist problems.
2224 * pairs.h (SCM_NEWCELL): New debugging version added.
2225 * gc.h (scm_debug_newcell): Added extern declaration, used by
2226 debugging version of SCM_NEWCELL.
2228 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2230 On some systems <libc.h> conflicts with <unistd.h>, and should not
2231 be #included at all.
2232 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
2233 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
2234 * configure.in: Call it.
2235 * posix.c, filesys.c: Use its results to decide whether or not to
2237 * configure, scmconfig.h.in: Rebuilt with autoconf and
2240 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2242 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
2243 pointer to the stdio stream before calling scm_setbuf0, so the
2244 latter will be able to retrieve it. I'm surprised this didn't
2245 segfault earlier. (Thanks to Christopher Lee.)
2247 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2249 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
2252 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2254 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
2255 number of stack narrowing specifier pairs. The first specifier in
2256 a pair controls inner border, the second the outer border. A
2257 number means cut that number of frames, a procedure object means
2258 cut until that object is found in operator position in a frame.
2260 * root.c (cwdr): Bugfix.
2262 * read.c: Recording of positions disabled by default.
2264 * procs.c (scm_closure_p): New function.
2266 * posix.c (scm_tmpnam): New function.
2268 * load.c: Added #include "throw.h".
2269 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
2272 * load.c, load.h (scm_read_and_eval_x): New function.
2274 * eval.c: Renamed debug option "deval" to "debug".
2276 (scm_eval_x): `eval!' is no longer accessible from the scheme
2277 level. Motivation: We can't allow operations which introduce
2278 glocs into the scheme level. Guile's type system can't handle
2279 these as data. Use `eval' or `read-and-eval!' as replacement.
2281 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
2282 SCM_CONSP since this is a macro!; Set vframe.prev to
2283 scm_last_debug_frame instead of 0. In this way we can look
2284 "above" the virtual start stack frame if we wish.
2285 (scm_debug_hang): New function: Useful for debugging Guile in
2286 certain tricky situations. Will probably be removed later...
2288 * debug.h: Changed semantics of debug option "backtrace". This
2289 option now only indicates whether we want automatic backtrace at
2292 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2294 * ports.c: #include "filesys.h"
2295 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
2297 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
2298 Motivation: This is system specific code which is related to file
2299 I/O. It also may use select. Added code by Gary Houston to
2300 detect presence of character in stdio buffers.
2302 * libguile.h: #include "libguile/libpath.h"
2304 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
2305 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
2306 SCM_SITE_DIR; Install libpath.h among the other include files.
2308 * load.c, load.h (scm_sys_package_data_dir): New function.
2310 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2312 * stacks.h: Bugfix: Don't use tail-array length field as stack
2313 length field! This screwed GC.
2315 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2317 * _scm.h: Added #ifndef around definition of macros min and max.
2319 * __scm.h: Added hooks for threads to plugin to in ints protection
2320 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
2321 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
2322 the main code in these macros duplicated and spread over multiple
2323 files. Renamed SCM_THREADS_SWITCHING_CODE ->
2324 SCM_THREAD_SWITCHING_CODE.
2326 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
2328 * snarf.h: New file.
2329 * guile-snarf.sh: New file.
2330 * Makefile.in (inner_h_files): Added snarf.h
2331 (ancillary, install, uninstall, distclean): Added actions for
2333 (.c.x): Use guile-snarf.
2334 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
2335 (gen_c_files): Note that these depend on guile-snarf.
2336 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
2337 now in "snarf.h". Added #include "snarf.h" to get them.
2338 * libguile.h: Added #include "snarf.h".
2339 (Patches applied and tweaked by Jim Blandy.)
2341 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
2343 * socket.c: Use K&R style declaration for 'close'; the GNU coding
2344 standards suggest against providing prototypes for system
2345 functions. Thanks to Greg Troxel.
2347 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
2349 * strports.c (scm_eval_0str): New function.
2350 #include "read.h", to get prototype for scm_read.
2351 * Makefile.in (strports.o): Update dependencies.
2352 * strports.h: New prototype.
2354 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
2355 scheme name from "int?" to "integer?". It seems to do the job.
2356 * numbers.h: Rename prototype too.
2357 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
2360 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
2361 scm_num_eq_p): Rename these according to R4RS conventions: call
2362 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
2363 to making libguile R4RS compliant without ice-9...
2365 * load.c (scm_sys_search_load_path): Search for files under all
2366 extensions listed in the %load-extensions variable. If FILENAME
2367 is absolute, return it unchanged, without searching the load path.
2368 (scm_loc_load_extensions): New variable, pointing to
2369 %load-extensions' value cell.
2370 (scm_init_load): Initialize it, and the value it points to.
2371 (scm_primitive_load_path): Improve error reporting.
2373 * load.c (scm_loc_load_hook): New variable, pointing to value cell
2374 of new Scheme variable %load-hook.
2375 (scm_primitive_load): Apply %load-hook to filename.
2377 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
2379 * configure.in: add tests for figuring out whether buffered data
2380 is available in a FILE structure, which is needed by char-ready.
2382 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
2385 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
2386 exceptions using misc_error instead of syserror. It seems a bit
2387 odd to throw an exception if a string can't be found in the
2388 environment, but it's consistent with open-file, stat etc.
2389 (simpos.h): remove sys_ from getenv.
2391 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
2392 occurs, throw an error instead of returning errno. Return value
2394 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
2396 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
2398 * filesys.c (scm_stat2scm): derive file type and permissions from
2399 the stat mode and append them to the returned vector.
2400 There isn't much overhead in doing this and it avoids the need to
2401 work with S_IRUSR et al. in Scheme.
2402 Define symbols scm_sym_regular etc.
2403 (scm_init_filesys): don't intern S_IRUSR etc.
2405 * load.c: change s_try_load and s_try_load_path to s_primitive_load
2406 and s_primitive_load_path.
2408 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
2410 * error.h: don't declare error symbols. prototype for scm_misc_error.
2412 * stackchk.c (scm_stack_overflow_key): defined here instead of in
2415 * error.c: use SCM_SYMBOL to set up error keys.
2416 scm_misc_error: new procedure.
2418 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2420 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
2421 between `#!' and `!#' is ignored.
2422 (skip_scsh_block_comment): New function.
2424 * feature.c (scm_set_program_arguments): New argument, FIRST.
2425 * feature.h: Update prototype.
2426 * init.c (scm_boot_guile_1): Pass new argument to
2427 scm_set_program_arguments.
2429 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
2431 * init.c (scm_start_stack): Don't initialize scm_progargs here.
2432 (scm_boot_guile): Call scm_set_program_arguments here, later than
2433 the old initialization.
2435 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
2436 initialization procedure.
2437 - Delete in, out, err arguments; there are other perfectly good
2438 ways to override these when desired.
2439 - Delete result argument; this function shouldn't ever return.
2440 - Rename init_func argument to main_func, for less confusion.
2441 - Delete boot_cmd argument; main_func is more general.
2442 -Add 'closure' argument, to help people pass data to main_func
2443 without resorting to global variables.
2444 - Abort if reentered; don't bother returning an error code.
2445 - Call scm_init_standard_ports to set up the default/current
2446 standard ports; no need to pass them to scm_start_stack.
2447 - Remove code to evaluate the boot_cmd, and start the repl; let
2448 the user do something like that in main_func if they want.
2449 - Remove code to package up a return value; main_func can do any
2451 - Call exit (0), instead of returning.
2452 (scm_start_stack): Don't initialize the I/O ports here; that's
2453 weird. Delete in, out, err arguments. Move guts to
2454 scm_init_standard_ports, scm_stdio_to_port.
2455 (scm_init_standard_ports): New function, to set up current and
2456 default standard ports.
2457 (scm_start_stack, scm_restart_stack): Make these static.
2458 * init.h (scm_boot_guile): Adjust declaration.
2459 (scm_start_stack, scm_restart_stack): Remove externally
2460 visible declarations for these.
2461 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
2463 * fports.c (scm_stdio_to_port): New function. Its guts used to be
2464 written out several times in scm_start_stack.
2465 * fports.h: New declaration for the above.
2467 * feature.c (scm_set_program_arguments): New function.
2468 * feature.h: New declaration for the above.
2470 * ports.c: Formatting tweak.
2472 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
2474 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
2475 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
2476 for obtaining the address of a car or cdr field. Motivation:
2477 &SCM_CXR make assumptions about the internal structure of the
2480 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
2481 Motivation: see SCM_CXRLOC.
2483 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
2484 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
2485 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
2486 Motivation: Safer use. Some other macros are defined in terms of
2487 these operations. If these are defined using the SCM_SETCXR
2488 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
2489 to inefficiency and an <e1> with side-effects could potentially
2490 break. Also, these particular operations are heavily utilized in
2491 the garbage collector. In unoptimized code there will be a
2494 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
2495 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
2496 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
2497 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
2498 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
2499 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
2500 vports.c: Cleaned up use of pairs: Don't make any special
2501 assumptions about the internal structure of selectors and
2502 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
2503 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
2504 (Among other things, this change makes it easier to build Guile
2505 with certain compilers which have problems with casted lvalues.)
2507 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2509 * stacks.c: Improve selection of relevant stack frames when making
2510 a stack object. Introduce one level of indirection in the stack
2511 object to make it possible to "narrow" to a certain region of the
2512 stack. This facilitates making use of more clever algorithms (not
2513 implemented) for selecting relevant frames and gives a cleaner
2514 design since selection of frames can be done independently of
2515 extraction of frames from the real stack.
2516 (scm_stack_id): Also take #t as argument which means look at
2519 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
2520 Turn n_tail into an integer directly representing current number
2521 of frames in stack. Add field tail.
2523 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
2525 * debug.c (scm_make_memoized): Made it available at scheme level.
2526 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
2527 SCM_NIMP before applying heavier predicates in argument checking.
2528 (scm_local_eval): Also take memoized object as argument.
2530 * backtrace.c (scm_display_error): Just a safety measure: Stacks
2531 aren't created with zero length, but should such a strange
2532 creature suddenly turn up...
2534 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
2536 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
2537 `del', for the sake of C++ compilers. (Patch applied by JimB.)
2539 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
2541 * variable.c (scm_make_variable): Make the name hint optional, as
2543 (anonymous_variable_sym): Renamed from variable_sym. All uses
2546 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
2547 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
2548 of scm_primitive_load_path was also changed to
2549 "primitive-load-path", from "%try-load-path". Callers changed.
2550 We'd like to respect the convention that a function named
2551 "try-mumble" should behave just like the function called "mumble",
2552 but return #f instead of signalling some error.
2553 * load.h: Rename prototypes.
2555 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2557 * print.c (make_print_state, grow_print_state), print.h: Modified
2558 the print state representation: Don't use a tail array for
2559 recording of circular references. Resizing of the print state
2560 structure invalidates the print state pointer. To avoid passing
2561 around an indirect print state reference to all printing
2562 functions, we instead let the print state reference a resizable
2565 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2567 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
2568 Don't crash when passed an improper list terminated by a
2569 non-immediate value.
2571 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
2573 Allocate data for structures on an eight-byte boundary, as
2574 required by the tagging system.
2575 * struct.c (alloc_struct): New function.
2576 (scm_make_struct, scm_make_vtable_vtable): Call it.
2577 * struct.h (scm_struct_n_extra_words): Bump to 3.
2578 (scm_struct_i_ptr): New "field".
2579 * gc.c (scm_gc_sweep): When we need to free the data, use the
2580 information stored by alloc_struct to find the beginning of the
2581 block allocated to the structure, so we can free it.
2583 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2585 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
2588 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
2589 (scm_debug_info): New member: id.
2591 * stacks.c: Stacks are now represented as structs; Stacks have an
2592 id given to them by `start-stack'.
2593 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
2595 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
2596 Changed stack representation.
2598 * debug.c (scm_procedure_name): Try procedure property `name' for
2599 compiled closures aswell.
2601 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
2603 * eval.c: scm_i_name moved to gsubr.c
2604 (scm_m_define): Record names of all kinds of procedure
2605 objects. (Earlier, only closures were recorded.)
2607 * procprop.h: Added declaration of scm_i_name.
2609 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
2610 (scm_make_gsubr): Record names of compiled closures.
2612 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2614 * debug.c, debug.h: Removed obsolete code.
2616 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
2617 stacks.c: Renamed regs --> scm_contregs.
2619 * print.c (scm_free_print_state): Cleanup print state before
2620 returning it to pool. It is better to do it here than in
2621 scm_prin1 since scm_prin1 is called often.
2623 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
2624 s_set_source_property_x): Check that first argument is a pair or a
2627 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
2628 scm_i_line, scm_i_column and scm_i_breakpoint global.
2630 * init.c: Added #include "backtrace.h" and #include "stacks.h".
2631 (scm_boot_guile_1): Added calls to scm_init_backtrace and
2634 * debug.h: Added debug object smob declaration and macro
2637 * configure.in: Build with backtrace.o and stacks.o if debug
2640 * Makefile.in: Added entries for new files: backtrace.c,
2641 backtrace.h, stacks.c and stacks.h.
2643 * symbols.c (scm_sym2ovcell): Fixed documentation.
2645 * _scm.h (min, max): Added.
2647 * async.c: Moved `min' macro to _scm.h.
2649 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
2650 SCM_BACKTRACE_INDENT.
2652 * eval.c: Added new debug options `maxdepth' and `indent'.
2654 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
2656 * print.h: Added selector SCM_PRINT_STATE.
2658 * print.c: New functions: scm_make_print_state,
2659 scm_free_print_state.
2661 * print.h: Added declarations for scm_make_print_state,
2662 scm_free_print_state.
2664 * debug.c (scm_m_start_stack): New acro.
2666 * debug.h: Small cleanup.
2668 * init.c (scm_boot_guile_1): Moved scm_init_debug below
2671 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

2691 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
2692 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
2693 declare functions with prototypes. (Patch thanks to Marius
2696 More prototype-related changes from Marius Vollmer:
2697 * gdb_interface.h: Wrapped header file in #ifdef/#endif
2698 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
2699 * ports.h (ptobfuns): Added prototypes. This means some casting in
2701 * fports.c: Added casts for initializations, since the functions
2702 are defined to take FILE * as their stream argument, not SCM.
2703 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
2704 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
2705 to `char *str_data' to conform to prototype.
2707 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2709 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
2711 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
2713 * stime.c, stime.h: use SCM_P method.
2715 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2717 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
2718 be given at least two arguments. Insist that lst's last element
2719 be a list, but don't make any requirements of its predecessors.
2721 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2723 * eval.c (scm_nconc2last): Revert last change; there seems to be
2724 other stuff going on here.
2726 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2728 * eval.c (scm_nconc2last): Make sure that each element of lst
2729 (which is a list of argument lists, except for the tail) is a
2730 proper list, i.e., finite and terminated by '().
2732 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
2734 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
2737 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
2738 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
2741 * vectors.c (scm_make_vector): Fill vectors with the undefined
2742 value, to help make Guile Scheme code more portable to other
2745 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
2746 * symbols.h, tags.h: Doc fixes.
2748 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
2750 * async.c (scm_take_signal): Doc fixes.
2752 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
2754 * numbers.c (scm_divbigint): When the remainder is zero, we don't
2755 want to subtract it from the modulus; we just want to leave it
2758 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
2760 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
2763 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
2765 * throw.c (scm_catch_apply): Finished implementation of
2768 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2770 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
2772 (scm_init_filesys): set "i/o-extensions" feature.
2775 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
2777 * Makefile.in (root.o): Correct dependencies.
2779 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
2781 * Makefile.in: Added dependency entry for root.o.
2783 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
2784 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
2786 * init.c (scm_start_stack): Set initial root continuation number
2789 * procs.c: New function: scm_thunk_p.
2791 * procs.h: Added declarations of scm_thunk_p.
2793 * root.c: Renamed `call-with-new-root' -->
2794 `call-with-dynamic-root'.
2795 (cwdr): Removed allocation of new root state. This should be done
2796 separately by use of scm_make_root.
2797 (scm_apply_with_dynamic_root): New function: Does what it
2798 sounds like. Needed when spawning threads.
2800 * root.h: Added member last_debug_frame to root state.
2801 Added #include "libguile/debug.h"
2803 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
2804 arguments. The motivation is that code in root.c needs catch
2805 functionality, and we want to avoid code duplication.
2806 New functions: scm_catch, scm_lazy_catch. These are wrappers for
2807 scm_catch_apply. scm_lazy_catch is intended to introduce catch
2808 handlers that run without popping the stack into the dynwind
2811 * throw.h: Added prototypes for scm_catch_apply and
2814 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2816 * root.h (scm_root, scm_set_root): Decouple thread support details
2817 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
2818 SCM_SET_THREAD_LOCAL_DATA.
2820 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
2821 and tortoise scanning loop.
2823 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
2825 * Makefile.in: Rebuild dependencies.
2827 * libguile.h: #include "libguile/print.h" before "smob.h", since
2828 the latter uses the print_state structure.
2830 * throw.c (scm_ithrow): Use the correct variable when checking to
2831 see if a given element of scm_dynwinds is a valid catch.
2833 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
2834 structure, abort; don't just silently ignore the garbage.
2836 * _scm.h: #include "print.h" here, since it seems to be used just
2838 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
2839 strports.c, unif.h: Don't #include "print.h".
2841 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2843 * feature.h (scm_loc_features): Removed external declaration.
2844 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
2846 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2848 * feature.c (scm_init_feature): Added threads feature (needs to be
2849 initialized here, since features doesn't exist when
2850 scm_init_threads is called).
2852 * libguile.h: Added #include "libguile/../threads/threads.h".
2853 (This is a kludge to get thread support working. This should be
2856 * configure.in, acconfig.h: Added flags for thread support.
2858 * scmsigs.c: Define `signal' to be `pthread_signal' if using
2861 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
2862 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
2865 * _scm.h: Added conditional #include "threads.h"
2867 * __scm.h (SCM_ASYNC_TICK): Added call to macro
2868 SCM_THREADS_SWITCHING_CODE.
2870 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
2871 allocate the basic dynamic root object.
2872 (scm_boot_guile): Added call to scm_init_root.
2874 * root.c, root.h: Added root smob.
2875 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
2876 functions: Implements dynamic roots mostly according to spec in
2877 SCM manual. Main difference is that the second argument is a
2878 throw handler rather than an error "thunk".
2880 * root.h: Added declaration of scm_init_root.
2882 * root.c: Added #include "genio.h", #include "smob.h", #include
2883 "pairs.h", #include "throw.h", #include "dynwind.h", #include
2885 (scm_init_root): Added #include "root.x".
2887 * throw.c: Added #include "stackchk.h"
2888 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
2889 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
2890 can be used in scm_call_with_new_root; Added reenabling of stack
2891 checking when catching a throw.
2893 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
2895 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
2897 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
2898 element is not found, as per R4RS.
2900 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2902 * list.c: Doc fixes throughout.
2904 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2906 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
2907 declare the char * to be const. Avoids a warning in rgx.c.
2909 * ports.h: spelling fix.
2911 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
2914 * load.c (scm_sys_try_load_path): throw an error if file not found
2915 (like it says it in NEWS).
2917 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2919 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
2920 PROPS slot to '(), not #f; it's an empty alist.
2922 * throw.h, throw.c: Use SCM_P instead of #if hair.
2924 Remove special support for uncaught throws; see throw.c for
2926 * throw.c (uncaught_throw): New function.
2927 (scm_ithrow): Call uncaught_throw if we don't find a throw
2928 target; don't mess with scm_bad_throw_vcell.
2929 (scm_bad_throw_vcell): Variable deleted.
2930 (scm_init_throw): Don't initialize it.
2932 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
2935 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2937 * numbers.c (scm_istr2int): If the number is short (as most
2938 numbers are), just call scm_small_istr2int to deal with it.
2939 (scm_small_istr2int): New function, created by un-#ifdefing the
2940 non-bignum version of scm_istr2int and renaming it.
2942 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
2944 * load.c (scm_sys_try_load): don't check whether value returned
2945 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
2946 Change the Scheme name from %try-load to primitive-load.
2948 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
2949 Can avoid passing a message, allowing it to be derived in the
2950 error handler (e.g., if we want to throw to the key both from
2953 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
2955 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
2956 references now have a new appearance which is more compact and
2957 also gives a clue about what the target of the reference is.
2958 By setting parameters in the print state, more fancy printing can
2959 be achieved. This is used by the (not yet commited) backtrace
2962 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
2964 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
2967 * print.c: Added #include "struct.h". Removed function
2970 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
2971 scm_iprin1. Removed prototype for scm_prlist.
2973 * arbiters.c (prinarb),
2974 async.c (print_async),
2975 debug.c (prindebugobj, prinmemoized),
2976 eval.c (prinprom, prinmacro),
2977 filesys.c (scm_fd_print, scm_dir_print),
2979 mallocs.c (prinmalloc),
2980 numbers.c, numbers.h (scm_floprint, scm_bigprint),
2981 smob.h (scm_smobfuns),
2982 srcprop.c (prinsrcprops),
2984 unif.c, unif.h (scm_raprin1, rapr1),
2985 variable.c (prin_var): Changed argument `int writing' to
2986 `scm_print_state *pstate'.
2988 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
2989 that it will be called before scm_init_print.
2991 * print.c (scm_prin1): Print states are now allocated when calling
2992 scm_prin1 and then passed around to all printing functions as an
2993 argument. A cache `print_state_pool' enables reuse of print
2995 (scm_make_print_state): New function.
2996 (scm_iprin1): Adaption to print states.
2997 (scm_iprlist): An initial "hare and tortoise" scan brings down
2998 time complexity to O (depth * N). (Better time complexity will be
2999 achieved when the printing code is completely rewritten.)
3001 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3003 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
3004 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
3005 it gets done whether or not the cache variable has a value.
3007 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3009 Distinguish #f and ().
3010 * __scm.h: #undef SICP.
3011 * pairs.h (SCM_EOL): Delete this definition, equating it with
3013 * tags.h (SCM_EOL): Give it a new definition here; I think I found
3014 the value it used to have. Doc fixes, too.
3016 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
3018 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
3019 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
3020 Lord's implementation of structs, allowing for tail arrays as
3021 described in the manual. Also fixed some bugs. (Both the interface
3022 and the implementation should be improved.)
3024 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
3026 * print.c, print.h: Closures now print like #<procedure foo (x)>.
3027 People who whish to see the source can do `(print-enable 'source)'.
3028 Removed #ifdef DEBUG_EXTENSIONS.
3030 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
3032 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
3033 integer (assuming for now accepting an integer is a good thing).
3035 * error.c, fports.c: replace use of %S in lgh_error args with %s.
3036 %S will be used instead for write'ing arguments.
3038 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
3039 asserts. fix a few other asserts.
3040 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
3041 scm_uniform_vector_ref, scm_array_set_x,
3042 scm_dimensions_to_unform_array): change args in
3043 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
3044 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
3045 scm_substring_fill_x): likewise.
3046 gsubr.c (scm_gsubr_apply): likewise.
3047 eval.c (SCM_APPLY): likewise.
3049 * eval.c (4 places): replace scm_everr with lgh_error or
3052 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
3053 scm_memory_error): new procedures.
3054 scm_everr: deleted. can use scm_wta, dropping first two args.
3055 scm_error: convert NULL subr to SCM_BOOL_F.
3057 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
3060 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
3063 * error.c, error.h: new error keys: scm_arg_type_key,
3064 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
3066 scm_wta: reimplement using lgh_error instead of scm_everr.
3068 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
3070 * gdbint.c: scm_lread now has one more argument.
3072 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
3073 scm_port_\1; Added mutator scm_set_port_filename_x (used when
3074 loading source from non-file ports, which, e. g., happens when
3075 using the Emacs interface).
3077 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
3080 * read.c: Added code for recording of positions of source code
3081 expressions; New functions: recsexpr, scm_lreadrecparen;
3082 _scm_make_srcprops --> scm_make_srcprops
3083 (scm_flush_ws): Removed updating of positions counters. This work
3084 is already done by scm_gen_getc
3086 * read.h: Added prototype for scm_lreadrecparen
3088 * print.c: Added #include "alist.h"
3090 * eval.c: Added #include "hash.h"
3092 * eq.c: Added #include "ramap.h"
3094 * options.c: Documentation fixes.
3096 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
3097 (scm_init_srcprop): Adjusted size of initial source-whash. Name
3098 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
3099 --> scm_make_srcprops
3101 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
3102 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
3103 function calls in the definition of the whash access macros.
3105 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
3107 * init.c (scm_boot_guile): Add level of indirection to
3108 scm_boot_guile_1() to ensure that stack base pointer is properly
3109 initialized. There was no guarantee that variable i was the
3110 highest/lowest variable on stack (i.e. the call frame of
3111 scm_boot_guile was not completely protected from gc).
3113 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
3115 * ports.h (scm_port_table): put back file_name, it will be used to
3116 support debugging. Undo related changes in fports.c, ioext.c,
3119 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
3121 * ports.h (scm_port_table): remove file_name member for now, it seems
3123 * fports.c (scm_open_file): don't set file_name in PTAB.
3124 (prinfport): don't use file_name in PTAB.
3125 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
3126 * ports.c (scm_add_to_port_table): don't intialize file_name.
3127 (scm_port_file_name): remove for now.
3128 * gc.c (scm_gc_mark): don't mark PTAB file_name.
3130 * fports.h (scm_mkfile): prototype deleted.
3131 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
3133 * debug.c, unif.c: use scm_out_of_range instead of
3134 wta for range errors (ASSERT still needs work).
3136 * error.c, error.h (scm_out_of_range): new procedure.
3138 * error.c, error.h (scm_out_of_range_key): new key.
3140 * posix.c (scm_sync): #else was missing.
3142 * error.c, error.h: append _key to names scm_num_overflow and
3145 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
3146 of consing an empty list.
3147 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
3148 of macros, saves code and string space.
3149 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
3150 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
3151 lower case. Rename scm_syserror_m to scm_syserror_msg.
3152 error.h: prototypes for new procedures.
3154 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
3156 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
3158 * error.c, error.h: setup scm_num_overflow key.
3160 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
3161 Remove definition of SCM_OVSCM_FLOW.
3163 * fports.c (scm_open_file): use SCM_SYSERROR_M.
3165 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
3166 explicit message and args.
3168 * error.c, error.h, __scm.h: change system_error_sym to
3171 * error.c (system_error_sym): remove leading %% from the Scheme name
3174 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
3176 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3178 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
3179 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
3180 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
3181 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
3182 renamed. (These were introduced by unsupervised name
3185 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3187 * print.c: Added code for detection of circular references during
3188 printing. (init_ref_stack, grow_ref_stack): New functions. Added
3189 a hook for printing of closures (accessible via print options).
3190 This leads to a split of calls to scm_iprin1 into two classes:
3191 elementary print operations (e. g. the code which prints a smob)
3192 still use scm_iprin1 while top level calls (like scm_display) use
3193 scm_prin1. scm_prin1 begins by clearing the data structure used
3194 to record reference information.
3196 * print.h: Added declarations of scm_prin1 and scm_prlist.
3198 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
3200 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
3202 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
3204 * error.c (err_head): scm_iprin1 --> scm_prin1
3206 * debug.c: Adjusted header comment.
3210 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
3212 * strerror.c: Doc fix.
3214 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3216 * gdbint.c (gdb_read): Now possible to run during GC.
3217 (unmark_port, remark_port): New functions.
3219 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
3221 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
3222 of allocating a new string object. Also, increase size by
3223 the factor 2 instead of 1.5.
3225 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
3227 * __scm.h (SCM_P): Corrected to run under traditional C.
3229 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
3232 * async.c: Calls to scm_sysintern corrected.
3234 * async.h (scm_async_clock): Redundant declaration removed.
3236 * continuations.c (scm_dynthrow): Redundant declaration removed.
3238 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
3239 Definition typos corrected.
3241 * debug.h: Missing declarations of functions in debug.c added
3244 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
3245 Missing declarations to functions in eval.c added.
3247 * filesys.c: Possibly uninitialized variable rv.
3249 * gc.h (scm_object_addr, scm_unhash_name): Missing
3250 declarations of functions defined in gc.c added.
3252 * genio.c: Possible typos str_data -> wstr_data. ???
3254 * genio.c: Possibly unintended shadowing of local variable
3255 `int c' (gotos out of scope of inner `c'). ???
3257 * init.c: Uninitialized `SCM last' may be used.
3259 * ioext.h: (scm_sys_isatty_p): Typo.
3261 * list.h (scm_list_head): Missing prototype for function in
3264 * numbers.c (scm_two_doubles): Changed from extern to static
3265 (is used only within numbers.c).
3267 * numbers.h: Repeated declarations removed.
3269 * ports.h (scm_close_all_ports_except): Declaration for the
3270 function defined in ports.c added.
3272 * posix.h: Missing declarations added.
3274 * procs.h (scm_make_subr_opt): Missing declaration added.
3276 * socket.h (scm_sys_gethost): Missing declaration added.
3278 * socket.h: Redundant declarations removed (they are in fdsocket.h).
3280 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
3281 Missing declarations added.
3283 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
3285 * struct.c: Uninitialized variable `SCM answer' may be used.
3287 * unif.c (l2ra): Declaration prototype.
3289 * unif.c (scm_array_equal_p): Dummy definition removed (it is
3290 defined in ramap.c).
3292 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
3293 Redundant declarations removed (they are in ramap.h).
3295 * variable.h (scm_make_udvariable,
3296 scm_make_undefined_variable): Declaration corrected to
3297 correspond variable.c.
3299 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
3300 Missing declarations added.
3302 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
3304 * Makefile.in (distclean): Don't forget to delete fd.h.
3306 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3308 * fd.h.in, tags.h: Trivial cleanups.
3310 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
3311 marksweep.h just declared functions from gc.c.
3312 * gc.h, libguile.h: Don't #include "marksweep.h".
3313 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
3314 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
3315 dependencies updated.
3317 * libguile.h: Don't #include "files.h"; it's been deleted.
3319 * files.c (scm_sys_delete_file): Moved to filesys.c.
3320 File is now empty; deleted.
3322 * filesys.c: scm_sys_delete_file is now here. Remove
3323 #if's; they seem to rely on remnants of an old portability
3324 regimen. If the problems come up again, solve them properly,
3325 using autoconf. Specifically: Don't test M_SYSV, and #define
3326 remove to be unlink if it's #defined; don't use remove just
3327 because HAVE_STDC_HEADERS is #defined.
3328 * filesys.h: Add declarations for scm_sys_delete_file.
3329 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
3330 files.o, files.h, files.c, and files.x.
3331 * init.c: Don't #include "files.h", and don't call scm_init_files.
3333 Use SCM_P instead of PROTO; the latter intrudes on the user's
3335 * params.h: Deleted; definition of SCM_P moved to...
3336 * __scm.h: ... here, where it replaces PROTO macro.
3337 * libguile.h, smob.h: Don't #include "params.h".
3338 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
3339 smob.h: Fix prototypes accordingly.
3340 * Makefile.in: Update dependencies.
3341 (inner_h_files): Remove params.h.
3343 * gc.c: #include "gc.h"; every module should include its header,
3344 to let the compiler cross-check the declarations against the
3347 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
3348 simpos.h: #include "libguile/__scm.h".
3350 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
3352 * init.c: Don't forget to #include smob.h and init.h.
3353 * Makefile.in: Dependencies updated.
3355 * smob.h: Use PROTO instead of #if __STDC__.
3357 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
3359 * __scm.h: Doc fixes.
3361 * __scm.h, libguile.h: Use "quotes" in the #includes, not
3362 <angles>; this allows `make depends' to work properly.
3364 * libguile.h: #include smob.h and pairs.h before the others; they
3365 define typedefs used by other headers.
3367 C files should #include only the header files they need, not
3368 libguile.h (which #includes all the header files); the pointless
3369 recompilation was wasting my time.
3370 * Makefile.in (all .o dependency lists): Regenerated.
3371 * libguile.h: Don't try to get a definition for size_t here...
3372 * __scm.h: Do it here.
3373 * _scm.h: Since this is the internal libguile header, put things
3374 here that all (or a majority) of the libguile files will want.
3375 Don't #include <libguile.h> here; that generates dependencies on
3376 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
3377 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
3378 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and
3380 * alist.c: Get "eq.h", "list.h", "alist.h".

3477 * stackchk.h: #include "libguile/debug.h",
3479 * print.h, read.h: #include "options.h", since everyone who uses
3480 either of these files will need that.
3482 * smob.h: #include "ports.h", "genio.h", and "print.h", since
3483 anyone who uses this file will need them to define the smob
3484 printing functions. Also, get markers.h, since people will need
3485 to #define the mark functions.
3487 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
3488 * ports.h: ... to here.
3490 * ports.h (scm_port_table_size): Explicitly give type as 'int';
3491 don't rely on archaic C default type rules.
3493 * fports.h: #include "libguile/ports.h", since you need that in
3494 order to parse this.
3496 * genio.h: #include "libguile/print.h", because you need that to
3497 parse this; don't bother #including "ports.h", since print.h gets
3500 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
3502 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
3503 this; it's now a reference to an element of *scm_root.
3505 * debug.h: Don't #include "options.h"; the compiler won't be able
3506 to find that once the headers are installed; instead, #include
3507 "libguile/options.h".
3508 * gc.h: Same, with marksweep.h.
3509 * mbstrings.h: Same, with symbols.h.
3510 * scmhob.h: Same, with _scm.h.
3511 * smob.h: Same, with params.h.
3513 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
3514 C files; there's no need for this, and it forces recompilations
3517 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
3519 * error.c (scm_error): declare scm_error_callback.
3521 * error.h: prototype for scm_error_callback.
3523 * __scm.h: define lgh_error.
3524 (SCM_SYSERROR): redefine using lgh_error.
3526 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
3528 * error.c (scm_error): new procedure.
3530 * error.h: prototype for scm_error.
3532 * Makefile.in (install): install scmconfig.h from the current
3533 directory, not $(srcdir).
3535 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
3537 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3538 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3539 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
3540 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
3541 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
3542 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,

3544 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
3545 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3546 vports.h, weaks.h: #include "libguile/__scm.h", not
3547 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
3548 dependencies are within libguile properly.
3550 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
3552 * Makefile.in (.c.x): Simplify; there's no need to run this rule
3553 when scmconfig.h doesn't exist.
3555 * load.c (scm_sys_try_load): Correct spelling.
3557 * feature.c (scm_loc_features): Make this static.
3559 * Makefile.in (libpath.h): Omit trailing slash from path. We
3560 shouldn't require it of users, so why put it here?
3562 Move code to initialize and search %load-path from ice-9 to C
3563 code, so we can use the load-path to find the ice-9 boot code;
3564 this makes it easier to run Guile without installing it. See
3565 corresponding changes in guile/Makefile.in.
3566 * feature.c: Move stuff concerned with the load path to load.c.
3567 (scm_compiled_library_path): Deleted.
3568 Don't #include libpath.h here.
3569 * feature.h: Don't mention scm_compiled_library_path.
3570 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
3571 <sys/stat.h>, and <unistd.h> (if present).
3572 (R_OK): #define if the system hasn't deigned to.
3573 (scm_loc_load_path): New variable.
3574 (scm_init_load_path, scm_sys_search_load_path,
3575 scm_sys_try_load_path): New functions.
3576 (scm_init_load): Initialize scm_loc_load_path to point to the
3577 value cell of the Scheme %load-path variable.
3578 * load.h: Add declarations for scm_sys_search_load_path,
3579 scm_sys_try_load_path.
3580 * init.c: Call scm_init_load_path.
3581 * Makefile.in (feature.o, load.o): Dependencies updated.
3583 * load.c, load.h: Rewrite using PROTO macro.
3585 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3587 * gc.c (scm_cellp): New function: C predicate to determine if an
3588 SCM value can be regarded as a pointer to a cell on the heap.
3590 * gc.h: Added declaration of scm_cellp.
3592 * gdb_interface.h: New file: The GDB interface header from the GDB
3595 * gdbint.c: New file: GDB interface.
3597 * gdbint.h: New file: GDB interface.
3599 * libguile.h: Added #include <libguile/gdbint.h>.
3601 * init.c (scm_boot_guile): Added scm_init_gdbint.
3603 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
3604 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
3605 found if object files and source are kept separate).
3607 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
3609 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
3611 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
3613 * configure.in: Don't substitute the values of TCL_SRC_DIR and
3614 TK_SRC_DIR; they're not relevant any more.
3616 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
3617 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
3619 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
3621 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
3622 search path, so we can find the <libguile/MUMBLE.h> headers.
3624 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
3626 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
3627 implicit in the .c.o rule.
3628 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
3631 Put the library path in a header file, instead of passing it on
3632 the command line in every compilation.
3633 * Makefile.in (libpath.h): New target.
3634 (feature.o): Depend on libpath.h.
3635 (clean): Delete libpath.h.
3636 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
3637 * feature.c: ... #include "libpath.h" here.
3638 * .cvsignore: Ignore libpath.h.
3640 Don't install the unwashed masses of Guile header files in the
3641 main #include path; put most of them in a subdirectory called
3642 'libguile'. This avoids naming conflicts between Guile header
3643 files and system header files (of which there were a few).
3644 * Makefile.in (pkgincludedir): Deleted.
3645 (innerincludedir): New variable; this and $(includedir) are enough.
3646 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
3647 (installed_h_files): Divide this up. Now this variable lists
3648 those header files which should go into $(includedir) (i.e. appear
3649 directly in the #include path), and ...
3650 (inner_h_files): ... this new variable says which files appear in
3651 a subdirectory, and are referred to as <libguile/mumble.h>.
3652 (h_files): List them both.
3653 (install): Create innerincludedir, not pkgincludedir. Put
3654 the installed_h_files and inner_h_files in their proper places.
3655 (uninstall): Corresponding changes.
3656 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3657 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3658 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
3659 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
3660 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
3661 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
3662 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
3663 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
3664 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3665 vports.h, weaks.h: Find __scm.h in its new location.
3666 * __scm.h: Find scmconfig.h and tags.h in their new locations
3667 (they're both "inner" files).
3669 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
3671 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
3673 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
3675 * posix.c: Doc fixes.
3677 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
3679 * socket.c: Don't include a prototype for inet_aton; just use a
3680 K&R style declaration, to avoid warnings but minimize the chance
3681 of conflicts with the system.
3683 On NextStep, <utime.h> doesn't define struct utime, unless we
3684 #define _POSIX_SOURCE before #including it.
3685 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
3686 * acconfig.h: New comment text for above CPP symbol.
3687 * configure.in: Call it.
3688 * posix.c: #define _POSIX_SOURCE if it seems necessary.
3690 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
3692 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
3693 testing for __EMX__.
3695 * posix.c: #include <libc.h>, if it exists.
3697 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
3698 don't even know if the latter exists.
3700 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
3701 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
3702 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
3704 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
3706 (scm_init_posix): Use them when initializing the Scheme constants
3709 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3711 * Makefile.in (libdir, includedir, bindir): Use the
3712 autoconf-supplied values, instead of deriving them ourselves.
3713 (pkgincludedir, datadir, pkgdatadir): New variables.
3714 (install, uninstall): Put the header files in a special
3715 subdirectory, not in the main search path.
3717 * Makefile.in (ALL_CFLAGS): Provide the proper value for
3718 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
3720 * Makefile.in (IMPLPATH): Deleted; never used.
3722 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
3723 on the Tcl/Tk source any more.
3724 (INCLUDE_CFLAGS): Remove references to the above.
3726 * Makefile.in (version.o): Corrected dependencies.
3728 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
3730 * libguile.h: #include "version.h"
3732 * init.c (scm_boot_guile): Call scm_init_version.
3733 * gscm.c (gscm_run_scm): Call scm_init_version.
3735 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
3736 GUILE_VERSION): AC_DEFINE these.
3737 (acconfig.h): #undef the above symbols.
3739 * Makefile.in (libobjs): Add version.o.
3740 (installed_h_files): Add version.h.
3741 (c_files): Add version.c.
3742 (gen_c_files): Add version.x.
3743 (version.o): New rule.
3744 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
3745 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

3754 weaks.o): Add version.h to dependency lists.
3755 (markers.o): Remove duplicate rule.
3757 * version.h: New file.
3759 * version.c: New file.
3761 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3763 * symbols.c (scm_strhash): scm_downcase is now a function, not an
3764 array; use it appropriately. Since GCC is quite happy to
3765 subscript functions, it never warned us about this; we should use
3766 -Wpointer-arith in the future. I guess we never tested
3769 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3771 * socket.c: Doc and copyright fixes.
3773 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3775 * debug.c: Fixed and improved gdb support.
3777 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3779 * socket.c: Added declaration of inet_aton to avoid compiler
3780 warning. (Hope this solution is correct.)
3782 * stime.c: Added declaration of ftime. (This is missing in
3785 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
3787 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3789 * Makefile.in (c_files): add strerror.c.
3791 * strerror.c: new file from Emacs' sysdep.c.
3792 maybe configure should also check for sys_errlist.
3794 * configure.in (AC_REPLACE_FUNCS): add strerror.
3796 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3798 * debug.c (scm_init_debug): Added initialization for
3799 scm_evaluator_traps.
3801 * debug.h, debug.c: Various name changes.
3802 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
3803 "debug-options-interface". See commentary in options.c.
3805 * options.h, options.c: Options now have documentation strings.
3806 Also added a long explanatory commentary.
3808 * eval.c, print.h, print.c, read.h, read.c: Modifications to
3811 * gscm.c, init.c, root.c, throw.c: Bug fixes:
3812 last_debug_info_frame is now updated in all cases.
3814 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
3817 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3819 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
3820 Added option STACK_CHECKING.
3822 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3824 * Makefile.in: Added {debug,options,srcprop}.{h,c}
3826 * __scm.h: Removed symbols for debugging support.
3828 * acconfig.h: Added symbols for debugging support.
3830 * configure.in: Added user option for debugging support.
3831 --enable-debug will include the debugging code into libguile.a.
3833 * continuations.c (scm_make_cont): Enlarged the #if 0 around
3834 scm_relocate_chunk_to_heap.
3836 * debug.c: New file: low-level debugging support. It also
3837 includes support for debugging with gdb. (The extensions to gdb
3838 are written by Per Bothner at Cygnus.)
3840 * debug.h: New file: low-level debugging support.
3842 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
3843 argument pairs. Extensive modifications to the debugging
3844 evaluator. Added "SECTION:" commentaries to clarify what happens
3845 when, during double compilation. Renamed EVALIMP --> EVALIM.
3846 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
3847 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
3848 the beginning of the file. New procedure: scm_unmemocopy.
3849 Added some global state variables needed by the debugging
3850 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
3851 check_entry, check_apply, check_exit, debug_options and
3852 evaluator_traps. New acro: undefine.
3854 * eval.h: Renamed EVAL --> XEVAL.
3856 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
3857 --> scm_make_weak_key_hash_table.
3859 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
3860 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
3862 * libguile.h: Conditionally include debug.h
3864 * objprop.c (scm_object_properties, scm_set_object_properties_x):
3865 scm_object_properties shouldn't return handle. `handle' now gets
3866 initialized in scm_set_object_properties_x. scm_object_properties
3867 doesn't any longer create an entry in scm_object_whash.
3869 * options.c: New file: handling of run time options.
3871 * options.h: New file: handling of run time options.
3873 * posix.c (scm_getpgrp): Cast pointer to getpgrp.

3894 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3896 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
3898 * libguile.h: #include "objprop.h"; I guess this was forgotten.
3900 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
3901 and should be called by the final client.
3903 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
3905 * gc.h: Use the PROTO macro when declaring functions.
3906 * gc.c: Use the PROTO macro when declaring static functions.
3907 Remove the CPP hair around function definitions.
3909 * gc.c (scm_init_storage): Initialize scm_asyncs.
3911 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
3912 preprocessor symbol; "__scm.h" is where it might get #defined.
3913 * __scm.h: Similar: #include <scmconfig.h> before testing
3916 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
3918 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
3920 * init.c (scm_boot_guile): Add init_func argument; call
3921 (*init_func) instead of calling scm_appinit; it's ucky to
3922 hard-code names for the user's procedures.
3923 * init.h (scm_boot_guile): Adjust declaration.
3925 * __scm.h (PROTO): New macro, for declaring functions with
3928 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
3929 eliminate all the __STDC__ conditionals.
3930 (scm_boot_guile): Add declaration.
3931 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
3932 Remove __STDC__ conditionals around function definitions; the
3933 declarations in init.h will provide the same information, more
3936 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
3937 complain about it in the error message; the error message is
3938 adequate without that note, and there's nothing the user can do
3941 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
3943 * Makefile.in (ancillary): Drop def.sed.
3945 * posix.c (scm_init_posix): Use numeric values, rather than
3946 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
3947 F_OK. The symbols aren't available on some systems, and I'm
3948 pretty sure their values are fixed by common widespread practice.
3949 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
3951 More functions unavailable on some systems.
3952 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
3953 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
3955 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3956 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
3957 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
3958 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
3959 stub that signals an error as the #else.
3961 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
3963 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
3965 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
3967 * unif.c: include ramap.h.
3969 * read.c (endif): case_insensative_p renamed case_insensitive_p.
3971 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
3973 * ports.c: include sys/ioctl.h.
3975 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
3977 * configure.in: check for sys/ioctl.h.
3979 * ports.c: include <malloc.h> not "malloc.h".
3981 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3983 * fports.c: remove ttyname and tmpnam declarations.
3985 * posix.c: fewer ttyname declarations.
3987 * fports.c: include <string.h> not "string.h".
3989 * init.c, ioext.c: include string.h and unistd.h.
3991 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3993 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
3994 genio.c, simpos.c, vports.c: include string.h.
3996 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
3998 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
4000 (scm_addr_buffer_size): change type from scm_sizet to int.
4001 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
4002 from scm_sizet to int.
4004 * error.c: include unistd.h.
4006 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
4009 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
4011 * __scm.hd, def.sed: deleted.
4013 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
4015 Changes for NeXT, suggested by Robert Brown.
4016 * configure.in: Call AC_TYPE_MODE_T.
4017 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
4018 NeXT. Put header file list in alphabetical order.
4019 * configure, scmconfig.h.in: Regenerated.
4020 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
4022 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
4025 * acconfig.h: New file, providing documentation for the CPP
4026 symbols defined in configure.in
4027 * acconfig-1.5.h: Removed; superceded by the above.
4029 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
4031 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
4033 * fports.c (scm_open_file): don't return #f, throw error.
4035 * ioext.c (fileno): renamed from %fileno.
4036 (soft-fileno): deleted.
4038 * ports.c (scm_port_revealed): don't need to check for -1 from
4040 (scm_set_port_revealed_x): return unspecified, not #f.
4042 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
4044 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
4046 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
4048 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
4050 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4052 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
4053 This is necessary on Ultrix, and doesn't hurt portability.
4055 * Makefile.in (dist-dir): New target, implementing a new dist system.
4056 (installed_h_files): Put in alphabetical order.
4057 Remove duplicate entries for markers.h and unif.h.
4058 (c_files): Remove duplicate entries for markers.c.
4059 (ancillary): Renamed from anillery; all uses changed. Remove
4060 PLUGIN; it's a directory, and needs special treatment in dist-dir.
4061 Remove all the ../doc/* files; doc/Makefile.in handles that.
4063 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
4065 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
4066 every if must have an else, or else the whole command has a
4067 non-zero exit code whenever the if's condition is false.
4069 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
4071 * posix.c: include string.h.
4073 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4075 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
4078 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
4079 Remove leading % from scheme names.
4080 Do not return error values, call SCM_SYSERROR or similar.
4082 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
4084 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
4086 * struct.c (scm_init_struct): new file.
4088 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
4090 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
4091 (scm_list_head): added list-head for rapidly chopping argument
4092 lists off of longer lists (and similar).

4096 * objprop.c (scm_object_property): assq the cdr of the whash
4097 handle for obj, not the handle itself.
4099 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
4101 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
4102 weak hash tables last of all marking to avoid an obscure gc bug.
4103 WARNING: circular lists stored in a weak hash table will hose us.
4105 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
4107 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
4108 new functions similar to scm_substring_move_left_x and
4109 scm_substring_move_right_x.
4111 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
4113 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
4116 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
4118 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
4120 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
4122 * strports.c (scm_strprint_obj): convenience function. C for
4123 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
4125 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
4126 removed to a separate library
4128 * init.c (scm_boot_guile): copied from guile-tcl.c.
4129 Initialization specific to tcl interpreters removed.
4131 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
4133 * ports.c (scm_ports_prehistory): size malloced here doesn't
4134 matter so long as it is non-0 (got rid of "* 4").
4136 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
4138 * gscm.h: gscm_mkarray eliminated (presumably was not being used
4139 since its definition was bogus).
4141 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
4143 * mallocs.[ch]: back again (for rx at least).
4145 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
4147 * ports.c: removed functions relating to the mapping between ports
4148 and descriptors. (That stuff is unix-specific and should be collected
4149 in a separate library).
4151 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
4152 (Tom Mckay@avanticorp.com)
4154 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
4156 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
4157 handled correctly (SCM_FREEP was applied to them) -- test for
4158 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
4159 being overwritten with #f. (brown@grettir.bibliotech.com)
4161 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>

4191 NOTE: don't use a alist here.
4192 (scm_set_procedure_properties_x): fix type checking throughout this file.
4194 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
4196 * ports.c (scm_remove_from_port_table): adjust scm_mallocated

4202 * vports.c (scm_make_soft_port): allocate a port table entry
4203 (possibly triggering gc) before setting the tag of the corresponding
4206 * pairs.c (scm_delq_x): never throw an error.
4208 * vectors.c (scm_make_vector): made the default vector fill argument
4209 into '() (much more useful than the previous value, "#unspecified")
4211 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
4213 * ports.c (scm_add_to_port_table): Added fields
4214 to port table entries: file_name, line_num, col.
4215 Update these in open_file, gen_getc and gen_ungetc.
4216 Added procedures to access those fields.
4218 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
4220 * procs.c (scm_make_subr_opt): new entry point for making
4223 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
4225 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
4227 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
4229 * numbers.c (scm_exact_p): This function no longer
4230 implements "integer?".
4232 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
4234 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
4235 (scm_gc_stats): return an assoc of useful data. Replaces "room"
4236 and the stats reporting formerlly built into repl.
4238 * repl.[ch]: removed.
4239 GC statistics keeping moved to gc.c.
4240 Other statistics keeping can be done from Scheme.
4241 REPLS are now written in Scheme.

4248 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
4250 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
4252 * feature.c (scm_compiled_library_path): moved here from repl.c.
4253 This file is for stuff relating specifically to Scheme libraries
4256 * eval.c (scm_m_define): don't give warning about redefinition, don't
4259 NOTE: this should throw a resumable exception with parameters --
4260 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
4262 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.

4276 between the call to procedurep and use.
4278 * error.c (scm_everr):
4280 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
4283 * strports.c: don't reveal the port's string to the caller
4284 because it changes size.
4286 (stputc stwrite): check/change the strings length with interrupts
4289 * objprop.c (scm_set_object_property_x &c): use the generic
4290 hashing functions and be threadsafe.

4293 (per suggestion jaffer@gnu.ai.mit.edu).
4295 * mbstrings.c (scm_multi_byte_string): guard against argument list
4298 * strings.c (scm_make_string): loop cleanup

4326 initialization to fix a race condition.
4328 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

4330 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
4332 * throw.c (_scm_throw): Pass throwval on the stack, not in a global
4333 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
4335 * *.[ch]: namespace cleanup. Changed all (nearly) exported CPP
4336 and C symbols to begin with SCM_ or scm_.

4352 set the multi_byte flag correctly in symbols. This is wrong.
4353 intern_obbary_soft and msymbolize should take an extra parameter.
4354 Also, weird multibyte symbols don't print correctly.
4355 The weird symbol syntax is also a bit bogus (emacs doesn't quite
