12 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),

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

63 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
64 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
65 argument to SCM_ASSERT. Furthermore, the name of the function
66 should be passed as first argument when signalling
67 SCM_WNA. (Thanks to Thomas Morgan)
69 * gsubr.c (scm_gsubr_apply): From Radey Shouman
70 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
71 dispatches on the number of actual args has a default case
72 reporting an internal error. This is a vestige from a version
73 that mallocated a SCM vector to hold the arguments. In the
74 current version this check is too late: if it ever happens we will
75 have already overstepped the bounds of the array.
77 Also, the patch [...] adds a check for too many actual arguments."
79 mdj: Removed check for "internal programming error".
81 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>

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

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

332 (scm_init_regex_posix): Define constants for the REG_mumble flags;

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

402 * ports.h: new prototype.

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

420 top of the word, it should be unsigned.
422 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
423 is defined, to avoid warnings; it's only used in the
424 conflict-checking code. Which might go away anyway.
425 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
426 conditionals; put the label definition in an #if too, to stifle

483 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
484 23:47:01 1997" changelog: Slots are now initialized with `#f' by
485 default and not `()'. `#f' is the canonical non-value in Scheme,
488 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
490 * struct.c (struct_printer): New variable that holds a handle on
491 the Scheme variable *struct-printer*. This variable can be set by
492 Scheme code to override the printing of structures.
493 (scm_print_struct): If struct_printer is set, call it. If it is
494 not set, or returns #f, print the structure in the old fashion.
495 Include "eval.h" for scm_apply.
497 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
499 * struct.c (scm_struct_ref, scm_struct_set_x): Use
500 scm_struct_i_n_words to get the number of fields, not
501 -scm_struct_n_extra_words.
503 On the route to fancier struct printing:
504 * struct.c (scm_print_struct): New function to print a structure.
505 Include "genio.h" to support it. This function doesn't do
506 anything interesting right now, but I think it should be here
508 * struct.h: Include "print.h" and add prototype for
510 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
511 print structures ourself.
513 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
515 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
516 before applying the handler in case it doesn't return.
518 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
520 * scmsigs.h, async.h: updated.
522 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
525 * posix.c (scm_uname): interpret only negative values as an error.
526 Solaris normally returns a positive value.
528 * script.c (scm_compile_shell_switches): if we are not going into
529 an interactive repl, set scm_mask_ints to zero so that asyncs can
532 * simpos.c (scm_system): don't ignore/unignore signals around
535 * posix.c (scm_open_pipe): don't ignore/unignore signals around
538 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
539 done in boot-9.scm instead.
541 * scmsigs.c, async.c: Major rewriting of signal handling code.
542 (scm_sigaction): new procedure.
543 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
545 (scm_raise): return unspecified, throw error on failure.
547 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
549 * regex-posix.c (scm_init_regex_posix): Register the "regex"
550 feature, to help boot-9.scm decide whether to import the regex
553 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
555 * eval.c: Include scmconfig.h at the beginning of the file so that
556 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
559 * regex-posix.c: #include "_scm.h" before conditionally #including
560 <regex.h>; the former defines HAVE_REGCOMP.
562 * regex-posix.c: #include <regex.h> conditionally, so the file is
563 CPP'able (for dependency scanning) even on systems that don't have
566 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
568 Add new R4RS-compliant syntax for keywords.
569 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
570 regardless of the setting of the `keywords' read option.
571 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
572 can be re-read no matter what the setting of the `keywords' read
575 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
577 Add support for POSIX regular expressions.
579 * regex-posix.c, regex-posix.h: New files. (Some code
580 is taken liberally from rx/rgx.c in the old Guile dist.)
582 * init.c: Include regex-posix.h.
583 (scm_boot_guile_1): Call scm_init_regex_posix.
585 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
586 Add regex-posix.[ch] sources.
587 * Makefile.in: Regenerated.
589 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
590 to do this automatically? It didn't for me, bleh.)
592 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
594 * fports.c (print_pipe_port): New function.
595 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
596 latter doesn't even take the right arguments.
598 * Makefile.am: Increment shared lib revision number. I think
599 sometimes the uninstalled Guile finds the installed shared lib;
600 Gord says doing this might help. As things turned out, I can't
602 * Makefile.in: Regenerated.
604 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
605 passing it as the closure argument to scm_boot_guile. (Bill
608 * ports.c (print_void_port, putc_void_port, puts_void_port,
609 write_void_port, flush_void_port, getc_void_port, close_void_port,
610 noop0): Use ANSI prototypes instead of K&R declarations, so the
611 initialization of void_port_ptob gets aggressively type-checked.
612 Fix arguments of print_void_port and write_void_port. (Bill

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

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

747 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
748 (scm_display_error_message): use RO macros when strings may be RO.
749 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
750 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
751 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

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

992 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
994 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
995 have S_IFSOCK. This is the case under Ultrix.
997 * posix.c (scm_status_exit_val, scm_status_exit_val,
998 scm_status_term_sig, scm_status_stop_sig): Modified to work with
999 Ultrix versions of WIFSTOPPED, etc., which assume that their
1000 arguments are lvalues (hmm).
1002 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
1004 * eval.c: Doc fixes.
1006 * throw.c: Doc fixes; rearranged.
1008 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
1010 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
1012 * acconfig.h: Added entry for PACKAGE.
1013 * scmconfig.h.in: Regenerated.
1015 Changes to work with automake-1.1n, which has better libtool support.
1016 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
1017 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
1019 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
1021 * Makefile.in: Rebuild.
1023 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1025 * stime.c (scm_mktime): take an optional zone argument.
1026 (scm_localtime): check putenv return value.
1027 (scm_strftime, scm_strptime): moved from posix.c. move #include
1029 stime.h, posix.h: update prototypes.
1030 (bdtime2c, setzone, restorezone): new static procedures.
1031 (scm_mktime, scm_strftime): use them.
1032 (scm_strftime): don't call mktime before strftime. Use
1033 filltime for return value.
1034 (filltime): convert NULL zname to #f.
1035 (scm_strptime): return a count of characters consumed, not
1036 the remaining string.
1038 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1040 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.

1049 * stime.c (scm_init_stime): don't define ticks/sec.
1050 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
1051 return value problem and is still portable.)
1053 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
1055 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
1056 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
1057 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
1058 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
1059 cpp_err_symbols.c): Corresponding changes.
1060 * Makefile.in: Regenerated.
1062 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
1064 * posix.c (scm_putenv): don't check HAVE_PUTENV.
1065 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
1066 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
1067 * putenv.c: new file, from sh-utils 1.12.
1069 * posix.c (scm_environ): use malloc in place of scm_must_malloc
1070 since allocation isn't for Scheme objects.
1071 (scm_putenv): copy strings before placing in the environment.
1073 * stime.c (scm_current_time): throw an error if time returns -1,
1074 instead of returning #f.
1075 (scm_get_internal_real_time, scm_get_internal_real_time): use
1076 scm_long2num for return value instead of SCM_MAKINUM.
1078 * stime.h: prototypes updated.
1080 * stime.c (scm_time_in_msec): apparently unused, deleted.
1082 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
1084 * configure.in: check for gettimeofday.
1086 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
1087 which may be more usefully portable than a gettimeofday interface.
1089 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
1091 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
1093 * Makefile.in: Regenerated.
1095 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
1097 * stime.c (filltime): recovered static procedure.
1098 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
1101 * posix.h: add prototype for scm_close_pipe, remove prototypes for
1102 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
1104 * posix.c (scm_mknod): split the mode argument into type and perms
1105 arguments, like the extra fields returned by stat.
1107 * fports.c (scm_pipob): set the close, free and print procedures.
1108 (scm_close_pipe): new procedure.
1110 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
1111 define them in boot-9.scm
1113 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1115 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
1116 wan't defined. Don't include fd.h.
1118 * Previously fd.h was regenerated whenever configure was run,
1119 forcing a couple of files to be recompiled.
1121 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
1122 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
1123 Check for _fileno as well as _file.
1125 * ioext.c: don't fd.h.
1126 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
1129 * Change the stratigy for getting information about errno
1130 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
1131 generating lists of symbols during the build process, which will
1132 not always work, include comprehensive lists in the distribution.
1133 To help keep the lists up to date, the "check_signals" and
1134 "check_errnos" make targets can be used.
1136 * configure.in: don't check for a command to extract errno codes.
1137 * Makefile.am: update file lists, remove errnos.list and errnos.c
1138 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
1139 check_errnos targets.
1140 (CLEANFILES): remove errnos.c and errnos.list, add
1141 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
1142 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
1143 * errnos.default: deleted.
1144 * cpp_signal.c: new file.
1145 * cpp_errno.c: renamed from errnos_get.c.
1146 * cpp_err_symbols, cpp_sig_symbols: new files.
1147 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
1148 * error.c (scm_init_error): #include cpp_err_symbols instead of
1150 * posix.c (scm_init_posix): don't intern signal symbols. #include
1153 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
1155 * strop.c (scm_i_index): allow the lower bound to be equal to the
1156 length of the string, so a null string doesn't always give an error.
1158 * posix.h: new prototypes.
1159 * posix.c (scm_status_exit_val, scm_status_term_sig,
1160 scm_status_stop_sig): new functions, as in scsh. They break down
1161 process status values as returned by waitpid.
1163 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
1165 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
1166 configure doesn't know about it.
1168 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1170 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
1172 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
1173 which defines C variables with global linkage.
1175 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1177 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
1180 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
1182 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
1183 has time to check why this doesn't work well with continuations.
1185 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
1187 * Fix shell syntax error; some shells won't tolerate
1188 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
1190 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
1192 * posix.c (scm_uname): throw an error if uname fails instead
1195 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
1197 * error.c (err_head, scm_errno, scm_perror): obsolete procedures

1202 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1204 * acconfig.h: Removed PACKAGE.
1206 * scmconfig.h.in: Regenerated.
1208 * snarf.h: g++ says it's non-portable not to specify the first
1209 argument in a varargs declaration. I introduced the first
1210 argument by using preprocessor conditionals.
1212 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
1214 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
1215 (scm_freopen): use RO string macros for filename and modes.
1216 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
1218 * posix.c (scm_getgrgid): simplify conversion of name to C string.
1219 (scm_mknod): use RO string macros for path.
1221 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
1222 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
1224 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
1225 use SCM_ROSTRINGP and SCM_ROCHARS.
1227 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1229 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
1232 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
1233 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
1234 support for byte vectors.
1236 * print.c (scm_iprin1): Limit number of vector elements printed
1237 according to pstate->length.
1239 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
1241 * backtrace.c (scm_display_error_message): don't segv if message
1244 * error.h: prototype for scm_error_scm.
1246 * error.c (scm_error_scm): new procedure, reimplements scm-error
1247 in C and uses scm_error.
1249 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
1251 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
1252 pointer to the Scheme variable read-hash-procedures and intern it
1253 in scm_init_read. Modify scm_read_hash_extend and
1254 scm_get_hash_procedure to use the pointer.
1256 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1258 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
1259 (SCM_KEYWORD_STYLE): defined.
1261 * read.c (scm_read_opts): add a keywords option. This isn't a
1262 boolean option, in case someone wants to add support for DSSSL
1264 Setup scm_keyword_prefix symbol.
1265 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
1267 I've left keyword support disabled by default, since it doesn't
1268 seem to break the module system and it gives R4RS standard behaviour.
1269 It can be reactivated with (read-set! keywords 'prefix).
1271 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1273 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
1274 before constructing arbiter.
1276 * eval.c (scm_m_define): Bugfix: Check that the object is a
1277 closure before setting the procedure property!
1279 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
1281 * ports.c: Removed `ungetc-char-ready?'.
1283 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
1285 * read.c (scm_init_read): intitialise scm_read_hash_procedures
1286 (idea from Mikael: make it a pair so scm_permanent object only
1288 (scm_read_hash_extend): don't call scm_permanent_object.
1289 (ideas from Mikael): if chr is already in the list, replace its
1290 procedure instead of appending it again. If proc is #f, remove
1292 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
1294 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
1296 * gdbint.c (gdb_read): update scm_lreadr usage.
1298 * load.h: update prototypes.
1300 * load.c (scm_primitive_load, scm_read_and_eval_x,
1301 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
1303 * read.h: add prototype for scm_read_hash_extend. Change args for
1306 * read.c (scm_read_hash_procedures): new variable.
1307 (scm_read_hash_extend): new procedure.
1308 (scm_get_hash_procedure): new procedure.
1309 (scm_lreadr): use scm_get_hash_procedure instead of an argument
1310 for extended # processing.
1311 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
1312 scm_read_token): remove case_i, sharp arguments. Change callers.
1314 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
1316 * read.h (SCM_N_READ_OPTIONS): increase to 3.
1317 (SCM_CASE_INSENSITIVE_P): define.
1319 * read.c: add case-insensitive option to scm_read_opts.
1320 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
1321 to determine whether to convert symbol case.
1322 (default_case_i): definition removed.
1323 * read.c (scm_read_token): if case_i, downcase ic before doing
1326 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1328 * configure.in: Added configuration option `guile-debug'.
1329 Configure with --enable-guile-debug if you want a bunch of extra
1330 functions used for debugging when developing Guile.
1332 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
1334 * procs.c (make-cclo): New undocumented debugging procedure: Make
1335 compiled closure with internal procedure PROC and length LENGTH.
1336 Only compiled if GUILE_DEBUG is defined.
1338 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
1340 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
1342 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
1344 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
1345 with 3 or more args internally to the evaluator.
1347 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1349 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
1350 with 3 or more args internally to the evaluator. This is mainly
1351 because we don't want to pass entry and exit points of the
1352 debug support twice, but it also seems to increase the speed of
1353 the evaluator for such calls (e. g. (+ 1 2 3)).
1355 * backtrace.c (scm_display_application): New procedure:
1356 display-application; Set fancy printing parameters individually
1357 for different types of display (backtrace, error, application).
1358 (These should of course be customizable!)
1360 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
1361 clear the CHECK-flags.
1363 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1365 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
1367 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1369 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
1370 from pairs with a GLOC in the car.
1372 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
1373 otherwise `symbol-hash' will behave badly.
1374 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
1375 we get segmentation fault!
1377 * symbols.c: Added #include "weaks.h". New functions:
1378 `builtin-bindings' and `builtin-weak-bindings'. (These will be
1379 moved to an extraneous library when we split libguile.)
1381 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1383 * filesys.c (scm_stat): stat now takes fport arguments too as
1384 documented in the manual.
1386 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1388 * debug.c (scm_single_step): Bugfix: Call continuation with
1389 scm_call_continuation instead of throwing to it.
1391 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1393 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
1394 argument wasn't declared to be optional.
1396 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1398 * stime.c (scm_init_stime): Add feature "current-time".
1400 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
1402 * throw.h: prototype for scm_exit_status.
1403 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
1404 args to derive an exit status. Allows (quit) to work from a
1406 (scm_exit_status): new function.
1409 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1411 * eval.c (scm_deval): Removed some old code.
1412 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
1414 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
1417 * symbols.c (msymbolize): Bugfix: Must initialize property list to
1420 * procs.c: Introduce the existent C function scm_thunk_p at the
1421 Scheme level as well.
1423 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1425 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
1426 used from C to easily lookup the value of a symbol in the current
1429 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1431 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
1432 scm_init_unif in this file. This will also fix a previous problem
1435 * configure.in: Added AM_MAINTAINER_MODE
1437 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1439 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
1442 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1444 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
1445 source files that are not always included in libguile but should
1446 have their dependencies calculated by automake. This variable is
1447 recognized by automake, no further magic is needed.
1448 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
1449 to deal exclusively with *.lo files, as it seems. The *.o files
1450 are built automatically when the corresponding *.lo file gets
1453 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
1455 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
1458 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
1460 * unif.c (scm_array_set_x): minor change to argument error checking.
1462 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
1464 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
1465 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
1466 They should only be included in the library at configure.in's
1468 (libguile_la_LDADD): Include the appropriate .lo files here.
1469 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
1470 so we know when to build them (and their .lo bretheren).
1471 * configure.in (LIBLOBJS): New substituted variable. We let
1472 configure decide which .o files to include in LIBOBJS, and then
1473 put the corresponding list of .lo files in LIBLOBJS. The latter
1474 is what we pass to libtool.
1475 * Makefile.in, configure: regenerated.
1477 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
1479 * symbols.c (scm_sysintern0): New function. Contains the core of
1480 old scm_sysintern but doesn't take a second value argument.
1481 (scm_sysintern): Now uses scm_sysintern0.
1482 (scm_sysintern_no_module_lookup): Renamed to
1483 scm_sysintern0_no_module_lookup and doesn't take a second value
1484 argument any longer.
1486 * symbols.h (scm_sysintern0: Added declaration.
1488 * options.c (scm_init_opts): Use scm_sysintern0 instead of
1489 scm_sysintern when interning option keys. Otherwise we risk
1490 destroying the values of already interned variables.
1492 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
1493 scheme-level boolean (use SCM_NFALSEP).
1495 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
1497 (scm_backtrace): New function. (C version of old function from
1498 boot-9.scm) Motivation: Make it possible to display backtraces
1499 without depending on boot-9.scm. (I'm uncertain if this
1500 motivation is good enough...)
1502 * root.h (scm_root_state): Add member the_last_stack_var.
1503 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
1505 * root.c (mark_root): Mark scm_the_last_stack_var.
1507 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
1510 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
1512 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
1513 1. mark_lazy_catch didn't mark the smob.
1514 2. Both functions above have standard variants:
1515 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
1516 free_lazy_catch --> scm_free0.
1518 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
1520 * throw.c (scm_internal_lazy_catch): New function.
1521 (scm_lazy_catch): Rewritten to use it.
1522 (scm_ithrow): Handle the new lazy catch representation.
1523 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
1524 that doesn't have a jmpbuf is a lazy catch clause.
1525 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
1526 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
1527 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
1529 (scm_init_throw): Register the new lazy-catch smob type.
1530 * throw.h (scm_internal_lazy_catch): decl for new function.
1532 * throw.c (scm_internal_catch): Doc fixes.
1534 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
1535 configure.in. Including this might cause problems if applications
1536 that link against libguile include their own copies of alloca, but
1537 if they're using autoconf, they should be adding libguile to LIBS
1538 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
1539 the copy in libguile, and things will be okay. (I think.)
1541 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1543 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
1545 strop.h: move prototypes too.
1547 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
1549 * posix.c (scm_init_posix): don't intern EINTR since it's now done
1552 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
1553 etc. I deleted them from filesys.c long ago, but didn't
1554 notice they were here too (although ineffective since
1555 sys/stat.h wasn't included).
1557 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
1559 * eval.c: Don't define alloca in GCC case. gcc will automatically
1560 use __builtin_alloca if appropriate.
1562 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
1564 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
1565 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
1566 that values of automatic variables are preserved. See comments
1567 for safe_setjmp for details.
1569 Change from Thomas Morgan:
1570 * variable.c: Include eq.h.
1571 (var_equal): New function.
1572 (variable_smob): Use var_equal as the discriminator for variables.
1574 * throw.c (s_throw): Remove extraneous declaration.
1576 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
1577 * eval.c: Add necessary CPP cruft to support that.
1578 * configure, Makefile.in, scmconfig.h.in: regenerated.
1580 Change from Thomas Morgan:
1581 * procprop.c (scm_procedure_properties): Convert the Scheme
1582 boolean returned by scm_procedure_p into a C boolean before using
1583 it as a condition for SCM_ASSERT.
1584 (scm_procedure_property): Likewise.
1586 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
1587 indications of Unixness.
1590 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
1592 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
1594 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
1596 * read.c (scm_lreadr): use scm_misc_error to improve one of the
1597 "unknown # object" error messages.
1599 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
1600 (scm_i_index) and declare it static. Add a 'direction' argument
1601 to indicate what way the search should go.
1602 (scm_i_index): throw out-of-range error instead of wrong-type-arg
1604 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
1605 strop.h: remove scm_i_index, scm_i_rindex prototypes.
1607 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1609 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
1611 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
1612 to avoid clash with various scsh forks.
1614 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
1616 The following two changes (ramap.c, throw.c) are motivated by the
1617 apparent unportability of forward declarations of static arrays of
1618 the form `static foo bar[];'.
1620 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
1621 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
1623 * throw.c (scm_throw): Moved above scm_ithrow.
1625 * options.h: Removed the extern declarations of scm_yes_sym and
1626 scm_no_sym since these are static.
1628 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1630 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
1632 * Makefile.am: remove AWK=@AWK@.
1633 Add a rule for generating errnos.list.
1634 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
1636 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
1637 don't extract errnos, just set a variable (avoids the
1638 need to recompile error.c just because configure is run.)
1640 * unif.h: update prototypes.
1641 * unif.c (scm_uniform_array_read,write): change the offset and
1642 length arguments to start and end, for consistency.
1644 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
1646 * ioext.h: update prototypes.
1647 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
1648 scm_read_line_x, it's a more general procedure using an
1649 interface from scsh. read-line and read-line! are now defined
1651 Note that the new read-line trims the terminator
1652 by default, previously it was appended to the returned string. An
1653 optional argument specifies how to process the terminator (scsh
1654 compatible). For the old behaviour: (read-line port 'concat).
1655 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
1656 returns a pair, but is converted to multiple values if the scsh
1659 socket.h: update prototypes.
1660 * socket.c (scm_recvfrom): for consistency with other procedures,
1661 take start and end as separate optional arguments.
1662 (scm_recv, scm_recvfrom): don't allow the second argument
1663 to be a size, only a buffer. Change the scheme names to
1664 recv! and recvfrom!. Don't return the buffer.
1666 * ioext.h, posix.h: move prototypes too.
1667 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
1668 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
1669 "read.h" and "unif.h".
1670 * ioext.c: include "chars.h"
1672 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
1674 * dynl.c: The dynamic linking and module registration functions
1675 are now defined even when dynamic linking is not available for the
1676 host system. Some of their functionality can be done without
1677 dynamic linking; when it's really needed, they throw errors.
1679 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
1681 * configure.in: Only define DYNAMIC_LINKING when one of the system
1682 dependent functions is detected.
1683 * dynl.c (scm_dynamic_func): New function to get the address of a
1684 function in a dynamic object.
1685 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
1686 produced by scm_dynamic_func as the thing to call.
1688 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
1690 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
1691 (scm_register_module_xxx, scm_registered_modules,
1692 scm_clear_registered_modules): New functions.
1694 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
1696 * symbols.c (scm_sysintern): Renamed to
1697 scm_sysintern_no_module_lookup.
1698 (scm_sysintern): New function to take the place of the old
1699 scm_sysintern. It uses the current toplevel lookup closure to give
1700 the symbol its value. This is a temporary hack to put packages
1701 like gtcltk into their own module.
1702 (scm_can_use_top_level_lookup_closure_var): New variable to tell
1703 us whether `scm_top_level_lookup_closure_var' has been initialized
1705 * eval.c (scm_init_eval): Set it.
1707 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
1709 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
1710 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
1712 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
1714 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
1715 scm_sys_dup): deleted: FD capability will be added to other
1717 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
1718 scm_fd_free, fd_smob, scm_intern_fd.
1719 (scm_open): renamed from scm_sys_open. Return a port instead of
1720 an FD object. Make the mode argument optional.
1721 (scm_sys_create): deleted, it's just a special case of open.
1722 (scm_init_filesys): move interning of constants O_CREAT etc.,
1723 here (were previously using SCM_CONST_LONG macro).
1724 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
1726 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
1727 include "fports.h" and <stdio.h>
1728 (scm_stat, scm_select): don't support FD objects.
1730 * error.h: adjust scm_syserror_msg prototype.
1731 * error.c (scm_syserror_msg): take an extra argument for errno.
1732 Using the global value didn't always work, since it could be
1733 reset by procedure calls in the message or args arguments.
1735 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
1736 I don't understand why the check was there (and what about the
1739 * strop.c (scm_string_copy): allow shared substrings to be copied.
1741 * unif.h: corresponding change to prototypes.
1742 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
1743 recognize two new optional arguments: offset and length. Allow
1744 the port argument to be an integer (file descriptor, for scsh).
1745 Include <unistd.h> for "read" prototype.
1747 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
1749 * socket.c: don't include filesys.h.
1751 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
1753 * Makefile.am: add AWK=@AWK@ (?)
1755 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
1757 Add a rule to generate errnos.c from errnos.
1758 * error.c (scm_init_error): include errnos.c.
1759 * errnos_cnvt.awk: new file, converts the list of errno codes to
1761 * errnos_get.c: new file.
1762 * errnos.default: new file, contains errnos to try if they can't
1763 be extracted from errno.h.
1764 * configure.in: if using GCC, try and extract errno codes from
1768 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
1770 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
1771 * Makefile.am: Made libguile into a libtool library.
1772 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
1773 Set libtool_libs to indicate that libguile is a libtool library.
1774 See guile/ChangeLog for details.
1775 * .cvsignore: ignore "*.lo", the libtool library objects.
1777 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1779 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
1780 use htons in getservbyport argument.
1782 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
1784 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
1785 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
1788 * objprop.c (scm_object_property): No need to take the CDR of the
1789 value returned by scm_object_properties, since Aug 20 change.
1791 * configure.in: When checking for struct linger, #include
1792 <sys/types.h> as well as <sys/socket.h>. I've never known
1793 <sys/types.h> to cause any portability problems, and Solaris's
1794 <sys/socket.h> needs it.
1795 * configure: Rebuilt.
1797 I think the Sun compiler has chosen a perverse way to interpret
1798 ANSI declarations combined with K&R definitions. We'll
1799 appease it a little bit. But when it invades France, we fight.
1800 * print.c (scm_iprlist): Change 'tlr' argument to an int.
1801 * print.h (scm_iprlist): Here too.
1802 * numbers.c (scm_divbigdig): Change definition to match
1803 declaration in numbers.h.
1804 * unif.c (scm_makflo): Change definition to match declaration in
1807 * init.c (scm_boot_guile): Don't return the value of
1808 scm_boot_guile_1. This function doesn't return a value;
1809 scm_boot_guile_1 doesn't return a value (or return at all).
1811 * eval.c (unmemocopy): Add a semicolon to appease the Sun
1814 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
1815 compile. I have a feeling this function is a bad idea anyway ---
1816 one should always test for features, not systems.
1818 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
1819 semicolons. Only pure luck kept this from being noticed earlier.
1821 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
1823 * socket.c (scm_recvfrom): Added missing semicolon.
1825 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1827 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
1828 the buffer and start and end positions for scsh networking
1831 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
1833 * configure.in: Revert previous change to this file; the problem
1834 is due to transient automake weirdness.
1835 * configure: Rebuilt.
1837 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
1838 PLUGIN/guile.libs. configure generates the latter from the former.
1839 * Makefile.in: Rebuilt.
1841 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
1842 need this if we install scripts, like guile-snarf.
1843 * configure: Rebuilt.
1845 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1847 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
1849 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
1851 * socket.c (scm_addr_vector): fix faulty scm_listify.
1853 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
1855 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
1856 style block comment is no longer considered an error.
1858 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
1860 * PLUGIN/guile.libs.in: New file.
1861 * PLUGIN/guile.libs: Removed from repository.
1862 * configure.in: Create PLUGIN/guile.libs from
1863 PLUGIN/guile.libs.in. This is for including additonal libraries
1864 needed for dynamic linking.
1865 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
1866 instead of PLUGIN/guile.libs.
1868 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
1870 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
1872 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
1873 occurrences of the given element from the list, not just the
1874 first. This is how the Emacs Lisp functions behave, how the
1875 analogous Common Lisp functions behave, and (I believe) how the
1876 older Maclisp functions worked. I realize that this change may
1877 break code, but it seemed better to break it before the Guile
1880 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
1881 Their prototypes were already present in gc.h, but they weren't
1883 (scm_init_storage): Initialize scm_protects.
1884 * root.c (scm_protects): New element of scm_sys_protects.
1886 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
1888 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1890 * libguile.h: Added #include "libguile/net_db.h".
1892 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
1893 30 change. That file is only meant for communication between the
1894 configuration process and load.c. If code linked against libguile
1895 wants to get at the paths mentioned in libpath.h, it can call
1896 functions declared in load.h.
1898 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1900 * libguile.h: Removed #include "libguile/fdsocket.h"
1902 * net_db.c: Added #include <sys/socket.h>.
1904 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
1906 * filesys.c (scm_input_waiting_p): use select in preference to
1907 FIONREAD, since the latter doesn't detect EOF.
1908 Throw error if neither select nor FIONREAD available.
1910 * socket.c (scm_connect): take a port, not a fd object.
1911 (scm_fill_sockaddr): throw an error if fam is not recognised.
1912 (scm_bind): use scm_fill_sockaddr.
1913 (scm_listen): take a port, not a fd object.
1914 (scm_accept): take and return a port. return #f in the car if
1915 address can't be got
1916 (scm_sock_fd_to_port): new procedure.
1917 (scm_socket): use scm_sock_fd_to_port.
1918 (scm_addr_vector): throw error if unrecognised address type.
1919 take an extra argument with the calling procedure name.
1920 (scm_getsockname): take a port. return #f if address can't be got.
1921 (scm_getpeername): take a port. return #f if address can't be got.
1922 (scm_recvfrom): take a port. return #f for address component if can't
1924 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
1925 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
1927 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
1929 * throw.c (scm_internal_catch): Make body funcs and handler funcs
1930 use separate data pointers, to allow them to be designed
1931 independently and reused.
1932 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
1933 Renamed from catch_body, catch_handler, and uncaught_throw; made
1935 (struct scm_catch_body_data): Renamed from catch_body_data; moved
1937 (scm_catch): Use the above.
1938 (scm_throw): Don't bother printing a message for an uncaught
1939 throw; we establish a default handler in init.
1940 * throw.h (scm_internal_catch): Prototype updated.
1941 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
1943 (struct scm_body_thunk_data): New structure, used as data
1944 argument to scm_body_thunk.
1945 * init.c (struct main_func_closure): New structure, packaging up
1946 the data to pass to the user's main function.
1947 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
1948 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
1949 scm_internal_catch to establish a catch-all handler, using
1950 scm_handle_by_message. This replaces the special-case code in
1952 (invoke_main_func): Body function for scm_internal_catch; invoke
1953 the user's main function, using the main_func_closure pointer to
1954 decide what to pass it.
1955 * root.c (struct cwdr_body_data): Remove handler_proc member.
1956 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
1957 (cwdr_handler): Removed.
1959 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1961 * socket.h (SCM_P): update bind prototype.
1962 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
1963 include "feature.h".
1964 (scm_socket): return a port, not a file descriptor object.
1965 include "fports.h" and <unistd.h>
1966 (scm_bind): take a port, not a file descriptor object.
1967 take an extra argument for address args.
1969 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
1970 INADDR_NONE, INADDR_LOOPBACK.
1972 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1974 * init.c: include net_db.h and not fdsocket.h.
1975 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
1977 * Makefile.am: corresponding changes.
1978 * socket.h: renamed from fdsocket.h, fix names.
1979 * net_db.h: renamed from socket.h, fix names.
1980 * socket.c: renamed from fdsocket.c.
1981 remove _sys from procedure names.
1982 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
1983 add "socket" to features list.
1984 * net_db.c: renamed from socket.c.
1985 remove _sys from procedure names.
1986 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
1987 add "net-db" to features list.
1988 include "net_db.h". don't include <sys/socket.h> or
1991 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1993 * tags.h (scm_tags): Removed comma at end of last enumerator.
1995 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
1997 Don't use GCC extensions to allocate space for debugging frames.
1998 (Here he goes again! Why do we put up with this?!)
1999 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
2000 an scm_debug_info structure, not an in-line array of them. Add
2001 'info' member, to say how many vect elements we've used, for eval
2003 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
2004 a new variable debug_info_end to mark the end of vect, instead of
2005 the address of the 'info' pointer itself.
2006 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
2007 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
2008 (SCM_APPLY): Explicitly allocate space for debug.vect.
2009 * debug.c (scm_m_start_stack): Same, for vframe.vect.
2010 * stacks.c: Adjusted for new debug frame structure.
2011 (RELOC_INFO, RELOC_FRAME): New macros.
2012 (stack_depth, read_frames): Use them, and new scm_debug_frame
2013 element 'info', instead of magically knowing that eval frames have
2014 an info pointer sitting after vect.
2015 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
2017 (scm_init_stacks): Formatting tweaks.
2019 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
2021 Give GCC more control flow information, so it can be sure that
2022 variables aren't used uninitialized.
2023 * error.h (scm_error, scm_syserror, scm_syserror_msg,
2024 scm_sysmissing, scm_num_overflow, scm_out_of_range,
2025 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
2026 scm_misc_error): Tell GCC that these functions never return.
2027 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
2028 out the field type, call abort if SCM_ASSERT returns, to placate
2030 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
2031 scm_wta ever returns. We can't handle this case anyway, and this
2032 gives the optimizer more information.
2033 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
2034 scm_wta ever returns.
2036 In some cases, the code is fine, but GCC isn't smart enough to
2037 figure that out; this usually happens when one variable is only
2038 initialized and used when a particular condition holds true, and
2039 we know that condition will never change within a given invocation
2040 of the function. In this case, we simply initialize the variables
2041 to placate the compiler, hopefully to a value which will cause a
2042 crash if it is ever actually used.
2043 * print.c (scm_iprin1): Initialize mw_pos.
2044 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
2045 * throw.c (scm_ithrow): Initialize dynpair.
2046 * unif.c (scm_uniform_vector_ref): Initialize cra.
2047 * struct.c (init_struct): Initialize prot.
2048 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
2050 * strports.c (scm_eval_0str): Don't return uninitialized garbage
2051 if EXPR contains no expressions.
2053 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
2055 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
2056 cause an infinite loop (???). So much for the algebraic
2057 equivalency of variable-sized arrays and alloca...
2059 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
2061 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
2062 a SCM boolean, not a C boolean.
2064 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
2066 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
2067 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
2068 rules for raising scm_mtrigger. Previously, unfortunate but not
2069 unlikely circumstances could result in almost constant invokation
2070 of the gc. Now, this situations should be less likely, but they
2071 are not prevented completely.
2073 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
2075 * numbers.c (scm_fuck): Procedure removed; looks like old test
2077 * numbers.h: Prototype removed.
2079 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
2081 * debug.h (scm_debug_frame): Change `vect' member from an in-line
2082 array to a pointer, to match my Nov 21 change in eval.c.
2084 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2086 * libguile.h: Added #include "libguile/backtrace.h", #include
2087 "libguile/stacks.h".
2089 * strings.c (scm_string scm_make_string scm_string_ref
2090 scm_string_set_x scm_string_equal_p scm_string_append):
2091 Bugfix according to scm patch from Aubrey Jaffer:
2092 Corrected long-standing
2093 (not (eqv? (integer->char 128)
2094 (string-ref (make-string 1 (integer->char 128)) 0)))
2095 bug found by John Kozak <jk@noontide.demon.co.uk>.
2097 * strports.c, strports.h: Make scm_eval_0str return the value of
2098 the last expression evaluated (previously, it returned void).
2100 * strports.c, strports.h: New function: scm_read_0str. Does what
2103 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2105 * simpos.c (scm_getenv): return #f if string can't be found in the
2106 environment instead of throwing an exception, for compatibility
2107 with numerous other systems.
2109 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
2111 * Makefile.am (.c.x): Use guile-snarf.
2112 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
2114 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
2116 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
2118 * backtrace.c (scm_display_error_message): Made non-static, and
2119 renamed from display_error_message.
2120 * backtrace.h (scm_display_error_message): Added extern decl.
2121 * throw.c (uncaught_throw): Use it to display the error message.
2123 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
2125 * inet_aton.c: Use #if 0, not #ifdef 0.
2127 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
2129 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
2130 to convert the returned value.
2131 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
2132 the offset argument.
2134 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
2136 Add new interface to catch/throw, usable from C as well as
2138 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
2139 (scm_internal_catch): New function, replaces...
2140 (scm_catch_apply): Deleted.
2141 * throw.c (scm_catch_apply): Deleted; replaced with a more general
2142 mechanism which is a bit more code, but can be used nicely from C
2143 and implement the Scheme semantics as well.
2144 (scm_internal_catch): This is the replacement; it's named after
2145 the analogous function in Emacs.
2146 (scm_catch): Reimplemented in terms of the above.
2147 (struct catch_body_data, catch_body, catch_handler): New
2148 functions, used by scm_catch.
2149 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
2150 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
2151 support for new cwdr.
2153 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
2156 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
2158 * acconfig.h: Added DYNAMIC_LINKING symbol.
2159 * configure.in: Add option and checks for dynamic linking.
2160 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
2161 dynl.h: New files for dynamic linking support.
2162 * Makefile.am (libguile_a_SOURCES):
2164 (modinclude_HEADERS): Added "dynl.h".
2165 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
2167 * init.c (scm_boot_guile_1): Call
2168 scm_init_dynamic_linking to initialize dynamic linking support.
2170 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
2172 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
2173 (as we Schemers say). It needs to be global, so that I can tweak
2174 it for the proper operation of unexec.
2175 (scm_boot_guile_1_live): New variable, see above.
2177 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
2179 * guile-snarf.sh: Removed.
2180 * PLUGIN/guile.libs: Added dependency for -lm.
2181 * acinclude.m4: Renamed from aclocal.m4.
2182 * PLUGIN/greet: Removed.
2183 * Makefile.am, aclocal.m4: New files.
2184 * configure.in: Updated for Automake.
2186 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
2188 * eval.c (scm_definedp): Use top_level_lookup_closure_var
2189 and not top_level_lookup_thunk_var.
2191 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
2193 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
2195 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
2197 * eval.c (scm_definedp): Incompatibly changed to be a builtin
2198 Scheme function, instead of syntax. Single argument is now a
2201 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2203 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
2204 scm_ra_divide): Properly terminate statements passed as arguments
2205 to IVDEP macros. (Thanks to Bernard Urban.)
2207 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
2208 with non-constant sizes. (Thanks to Bernard Urban.)
2210 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
2212 It's an "eval closure", not an "eval thunk." A thunk is a
2213 function of no arguments.
2214 * root.h (struct scm_root_state): Renamed
2215 top_level_lookup_closure_var from top_level_lookup_thunk_var.
2216 (scm_top_level_lookup_closure_var): Renamed from
2217 scm_top_level_lookup_thunk_var.
2218 * root.c (mark_root): Uses changed.
2219 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
2220 * init.c (scm_start_stack): Uses changed.
2221 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
2222 Change scheme-visible name to *top-level-lookup-closure* from
2223 *top-level-lookup-thunk*.
2225 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
2227 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
2228 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
2230 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
2232 * gc.c (struct scm_heap_seg_data): Doc fixes.
2234 * gc.c (scm_gc_sweep): Empty all segments' freelists before
2235 sweeping. Then, prepend each segment's free cells to its
2236 freelist, rather than wiping out the old value. (Thanks to Marius
2239 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
2240 scm_check_freelist, scm_debug_newcell): New functions and
2241 variables, for debugging freelist problems.
2242 * pairs.h (SCM_NEWCELL): New debugging version added.
2243 * gc.h (scm_debug_newcell): Added extern declaration, used by
2244 debugging version of SCM_NEWCELL.
2246 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2248 On some systems <libc.h> conflicts with <unistd.h>, and should not
2249 be #included at all.
2250 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
2251 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
2252 * configure.in: Call it.
2253 * posix.c, filesys.c: Use its results to decide whether or not to
2255 * configure, scmconfig.h.in: Rebuilt with autoconf and
2258 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2260 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
2261 pointer to the stdio stream before calling scm_setbuf0, so the
2262 latter will be able to retrieve it. I'm surprised this didn't
2263 segfault earlier. (Thanks to Christopher Lee.)
2265 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2267 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
2270 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2272 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
2273 number of stack narrowing specifier pairs. The first specifier in
2274 a pair controls inner border, the second the outer border. A
2275 number means cut that number of frames, a procedure object means
2276 cut until that object is found in operator position in a frame.
2278 * root.c (cwdr): Bugfix.
2280 * read.c: Recording of positions disabled by default.
2282 * procs.c (scm_closure_p): New function.
2284 * posix.c (scm_tmpnam): New function.
2286 * load.c: Added #include "throw.h".
2287 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
2290 * load.c, load.h (scm_read_and_eval_x): New function.
2292 * eval.c: Renamed debug option "deval" to "debug".
2294 (scm_eval_x): `eval!' is no longer accessible from the scheme
2295 level. Motivation: We can't allow operations which introduce
2296 glocs into the scheme level. Guile's type system can't handle
2297 these as data. Use `eval' or `read-and-eval!' as replacement.
2299 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
2300 SCM_CONSP since this is a macro!; Set vframe.prev to
2301 scm_last_debug_frame instead of 0. In this way we can look
2302 "above" the virtual start stack frame if we wish.
2303 (scm_debug_hang): New function: Useful for debugging Guile in
2304 certain tricky situations. Will probably be removed later...
2306 * debug.h: Changed semantics of debug option "backtrace". This
2307 option now only indicates whether we want automatic backtrace at
2310 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2312 * ports.c: #include "filesys.h"
2313 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
2315 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
2316 Motivation: This is system specific code which is related to file
2317 I/O. It also may use select. Added code by Gary Houston to
2318 detect presence of character in stdio buffers.
2320 * libguile.h: #include "libguile/libpath.h"
2322 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
2323 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
2324 SCM_SITE_DIR; Install libpath.h among the other include files.
2326 * load.c, load.h (scm_sys_package_data_dir): New function.
2328 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2330 * stacks.h: Bugfix: Don't use tail-array length field as stack
2331 length field! This screwed GC.
2333 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2335 * _scm.h: Added #ifndef around definition of macros min and max.
2337 * __scm.h: Added hooks for threads to plugin to in ints protection
2338 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
2339 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
2340 the main code in these macros duplicated and spread over multiple
2341 files. Renamed SCM_THREADS_SWITCHING_CODE ->
2342 SCM_THREAD_SWITCHING_CODE.
2344 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
2346 * snarf.h: New file.
2347 * guile-snarf.sh: New file.
2348 * Makefile.in (inner_h_files): Added snarf.h
2349 (ancillary, install, uninstall, distclean): Added actions for
2351 (.c.x): Use guile-snarf.
2352 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
2353 (gen_c_files): Note that these depend on guile-snarf.
2354 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
2355 now in "snarf.h". Added #include "snarf.h" to get them.
2356 * libguile.h: Added #include "snarf.h".
2357 (Patches applied and tweaked by Jim Blandy.)
2359 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
2361 * socket.c: Use K&R style declaration for 'close'; the GNU coding
2362 standards suggest against providing prototypes for system
2363 functions. Thanks to Greg Troxel.
2365 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
2367 * strports.c (scm_eval_0str): New function.
2368 #include "read.h", to get prototype for scm_read.
2369 * Makefile.in (strports.o): Update dependencies.
2370 * strports.h: New prototype.
2372 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
2373 scheme name from "int?" to "integer?". It seems to do the job.
2374 * numbers.h: Rename prototype too.
2375 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
2378 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
2379 scm_num_eq_p): Rename these according to R4RS conventions: call
2380 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
2381 to making libguile R4RS compliant without ice-9...
2383 * load.c (scm_sys_search_load_path): Search for files under all
2384 extensions listed in the %load-extensions variable. If FILENAME
2385 is absolute, return it unchanged, without searching the load path.
2386 (scm_loc_load_extensions): New variable, pointing to
2387 %load-extensions' value cell.
2388 (scm_init_load): Initialize it, and the value it points to.
2389 (scm_primitive_load_path): Improve error reporting.
2391 * load.c (scm_loc_load_hook): New variable, pointing to value cell
2392 of new Scheme variable %load-hook.
2393 (scm_primitive_load): Apply %load-hook to filename.
2395 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
2397 * configure.in: add tests for figuring out whether buffered data
2398 is available in a FILE structure, which is needed by char-ready.
2400 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
2403 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
2404 exceptions using misc_error instead of syserror. It seems a bit
2405 odd to throw an exception if a string can't be found in the
2406 environment, but it's consistent with open-file, stat etc.
2407 (simpos.h): remove sys_ from getenv.
2409 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
2410 occurs, throw an error instead of returning errno. Return value
2412 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
2414 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
2416 * filesys.c (scm_stat2scm): derive file type and permissions from
2417 the stat mode and append them to the returned vector.
2418 There isn't much overhead in doing this and it avoids the need to
2419 work with S_IRUSR et al. in Scheme.
2420 Define symbols scm_sym_regular etc.
2421 (scm_init_filesys): don't intern S_IRUSR etc.
2423 * load.c: change s_try_load and s_try_load_path to s_primitive_load
2424 and s_primitive_load_path.
2426 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
2428 * error.h: don't declare error symbols. prototype for scm_misc_error.
2430 * stackchk.c (scm_stack_overflow_key): defined here instead of in
2433 * error.c: use SCM_SYMBOL to set up error keys.
2434 scm_misc_error: new procedure.
2436 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2438 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
2439 between `#!' and `!#' is ignored.
2440 (skip_scsh_block_comment): New function.
2442 * feature.c (scm_set_program_arguments): New argument, FIRST.
2443 * feature.h: Update prototype.
2444 * init.c (scm_boot_guile_1): Pass new argument to
2445 scm_set_program_arguments.
2447 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
2449 * init.c (scm_start_stack): Don't initialize scm_progargs here.
2450 (scm_boot_guile): Call scm_set_program_arguments here, later than
2451 the old initialization.
2453 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
2454 initialization procedure.
2455 - Delete in, out, err arguments; there are other perfectly good
2456 ways to override these when desired.
2457 - Delete result argument; this function shouldn't ever return.
2458 - Rename init_func argument to main_func, for less confusion.
2459 - Delete boot_cmd argument; main_func is more general.
2460 -Add 'closure' argument, to help people pass data to main_func
2461 without resorting to global variables.
2462 - Abort if reentered; don't bother returning an error code.
2463 - Call scm_init_standard_ports to set up the default/current
2464 standard ports; no need to pass them to scm_start_stack.
2465 - Remove code to evaluate the boot_cmd, and start the repl; let
2466 the user do something like that in main_func if they want.
2467 - Remove code to package up a return value; main_func can do any
2469 - Call exit (0), instead of returning.
2470 (scm_start_stack): Don't initialize the I/O ports here; that's
2471 weird. Delete in, out, err arguments. Move guts to
2472 scm_init_standard_ports, scm_stdio_to_port.
2473 (scm_init_standard_ports): New function, to set up current and
2474 default standard ports.
2475 (scm_start_stack, scm_restart_stack): Make these static.
2476 * init.h (scm_boot_guile): Adjust declaration.
2477 (scm_start_stack, scm_restart_stack): Remove externally
2478 visible declarations for these.
2479 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
2481 * fports.c (scm_stdio_to_port): New function. Its guts used to be
2482 written out several times in scm_start_stack.
2483 * fports.h: New declaration for the above.
2485 * feature.c (scm_set_program_arguments): New function.
2486 * feature.h: New declaration for the above.
2488 * ports.c: Formatting tweak.
2490 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
2492 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
2493 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
2494 for obtaining the address of a car or cdr field. Motivation:
2495 &SCM_CXR make assumptions about the internal structure of the
2498 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
2499 Motivation: see SCM_CXRLOC.
2501 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
2502 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
2503 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
2504 Motivation: Safer use. Some other macros are defined in terms of
2505 these operations. If these are defined using the SCM_SETCXR
2506 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
2507 to inefficiency and an <e1> with side-effects could potentially
2508 break. Also, these particular operations are heavily utilized in
2509 the garbage collector. In unoptimized code there will be a
2512 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
2513 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
2514 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
2515 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
2516 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
2517 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
2518 vports.c: Cleaned up use of pairs: Don't make any special
2519 assumptions about the internal structure of selectors and
2520 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
2521 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
2522 (Among other things, this change makes it easier to build Guile
2523 with certain compilers which have problems with casted lvalues.)
2525 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2527 * stacks.c: Improve selection of relevant stack frames when making
2528 a stack object. Introduce one level of indirection in the stack
2529 object to make it possible to "narrow" to a certain region of the
2530 stack. This facilitates making use of more clever algorithms (not
2531 implemented) for selecting relevant frames and gives a cleaner
2532 design since selection of frames can be done independently of
2533 extraction of frames from the real stack.
2534 (scm_stack_id): Also take #t as argument which means look at
2537 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
2538 Turn n_tail into an integer directly representing current number
2539 of frames in stack. Add field tail.
2541 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
2543 * debug.c (scm_make_memoized): Made it available at scheme level.
2544 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
2545 SCM_NIMP before applying heavier predicates in argument checking.
2546 (scm_local_eval): Also take memoized object as argument.
2548 * backtrace.c (scm_display_error): Just a safety measure: Stacks
2549 aren't created with zero length, but should such a strange
2550 creature suddenly turn up...
2552 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
2554 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
2555 `del', for the sake of C++ compilers. (Patch applied by JimB.)
2557 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
2559 * variable.c (scm_make_variable): Make the name hint optional, as
2561 (anonymous_variable_sym): Renamed from variable_sym. All uses
2564 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
2565 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
2566 of scm_primitive_load_path was also changed to
2567 "primitive-load-path", from "%try-load-path". Callers changed.
2568 We'd like to respect the convention that a function named
2569 "try-mumble" should behave just like the function called "mumble",
2570 but return #f instead of signalling some error.
2571 * load.h: Rename prototypes.
2573 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2575 * print.c (make_print_state, grow_print_state), print.h: Modified
2576 the print state representation: Don't use a tail array for
2577 recording of circular references. Resizing of the print state
2578 structure invalidates the print state pointer. To avoid passing
2579 around an indirect print state reference to all printing
2580 functions, we instead let the print state reference a resizable
2583 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2585 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
2586 Don't crash when passed an improper list terminated by a
2587 non-immediate value.
2589 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
2591 Allocate data for structures on an eight-byte boundary, as
2592 required by the tagging system.
2593 * struct.c (alloc_struct): New function.
2594 (scm_make_struct, scm_make_vtable_vtable): Call it.
2595 * struct.h (scm_struct_n_extra_words): Bump to 3.
2596 (scm_struct_i_ptr): New "field".
2597 * gc.c (scm_gc_sweep): When we need to free the data, use the
2598 information stored by alloc_struct to find the beginning of the
2599 block allocated to the structure, so we can free it.
2601 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2603 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
2606 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
2607 (scm_debug_info): New member: id.
2609 * stacks.c: Stacks are now represented as structs; Stacks have an
2610 id given to them by `start-stack'.
2611 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
2613 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
2614 Changed stack representation.
2616 * debug.c (scm_procedure_name): Try procedure property `name' for
2617 compiled closures aswell.
2619 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
2621 * eval.c: scm_i_name moved to gsubr.c
2622 (scm_m_define): Record names of all kinds of procedure
2623 objects. (Earlier, only closures were recorded.)
2625 * procprop.h: Added declaration of scm_i_name.
2627 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
2628 (scm_make_gsubr): Record names of compiled closures.
2630 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2632 * debug.c, debug.h: Removed obsolete code.
2634 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
2635 stacks.c: Renamed regs --> scm_contregs.
2637 * print.c (scm_free_print_state): Cleanup print state before
2638 returning it to pool. It is better to do it here than in
2639 scm_prin1 since scm_prin1 is called often.
2641 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
2642 s_set_source_property_x): Check that first argument is a pair or a
2645 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
2646 scm_i_line, scm_i_column and scm_i_breakpoint global.
2648 * init.c: Added #include "backtrace.h" and #include "stacks.h".
2649 (scm_boot_guile_1): Added calls to scm_init_backtrace and
2652 * debug.h: Added debug object smob declaration and macro
2655 * configure.in: Build with backtrace.o and stacks.o if debug
2658 * Makefile.in: Added entries for new files: backtrace.c,
2659 backtrace.h, stacks.c and stacks.h.
2661 * symbols.c (scm_sym2ovcell): Fixed documentation.
2663 * _scm.h (min, max): Added.
2665 * async.c: Moved `min' macro to _scm.h.
2667 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
2668 SCM_BACKTRACE_INDENT.
2670 * eval.c: Added new debug options `maxdepth' and `indent'.
2672 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
2674 * print.h: Added selector SCM_PRINT_STATE.
2676 * print.c: New functions: scm_make_print_state,
2677 scm_free_print_state.
2679 * print.h: Added declarations for scm_make_print_state,
2680 scm_free_print_state.
2682 * debug.c (scm_m_start_stack): New acro.
2684 * debug.h: Small cleanup.
2686 * init.c (scm_boot_guile_1): Moved scm_init_debug below
2689 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

2709 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
2710 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
2711 declare functions with prototypes. (Patch thanks to Marius
2714 More prototype-related changes from Marius Vollmer:
2715 * gdb_interface.h: Wrapped header file in #ifdef/#endif
2716 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
2717 * ports.h (ptobfuns): Added prototypes. This means some casting in
2719 * fports.c: Added casts for initializations, since the functions
2720 are defined to take FILE * as their stream argument, not SCM.
2721 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
2722 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
2723 to `char *str_data' to conform to prototype.
2725 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2727 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
2729 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
2731 * stime.c, stime.h: use SCM_P method.
2733 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2735 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
2736 be given at least two arguments. Insist that lst's last element
2737 be a list, but don't make any requirements of its predecessors.
2739 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2741 * eval.c (scm_nconc2last): Revert last change; there seems to be
2742 other stuff going on here.
2744 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2746 * eval.c (scm_nconc2last): Make sure that each element of lst
2747 (which is a list of argument lists, except for the tail) is a
2748 proper list, i.e., finite and terminated by '().
2750 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
2752 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
2755 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
2756 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
2759 * vectors.c (scm_make_vector): Fill vectors with the undefined
2760 value, to help make Guile Scheme code more portable to other
2763 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
2764 * symbols.h, tags.h: Doc fixes.
2766 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
2768 * async.c (scm_take_signal): Doc fixes.
2770 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
2772 * numbers.c (scm_divbigint): When the remainder is zero, we don't
2773 want to subtract it from the modulus; we just want to leave it
2776 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
2778 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
2781 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
2783 * throw.c (scm_catch_apply): Finished implementation of
2786 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2788 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
2790 (scm_init_filesys): set "i/o-extensions" feature.
2793 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
2795 * Makefile.in (root.o): Correct dependencies.
2797 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
2799 * Makefile.in: Added dependency entry for root.o.
2801 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
2802 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
2804 * init.c (scm_start_stack): Set initial root continuation number
2807 * procs.c: New function: scm_thunk_p.
2809 * procs.h: Added declarations of scm_thunk_p.
2811 * root.c: Renamed `call-with-new-root' -->
2812 `call-with-dynamic-root'.
2813 (cwdr): Removed allocation of new root state. This should be done
2814 separately by use of scm_make_root.
2815 (scm_apply_with_dynamic_root): New function: Does what it
2816 sounds like. Needed when spawning threads.
2818 * root.h: Added member last_debug_frame to root state.
2819 Added #include "libguile/debug.h"
2821 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
2822 arguments. The motivation is that code in root.c needs catch
2823 functionality, and we want to avoid code duplication.
2824 New functions: scm_catch, scm_lazy_catch. These are wrappers for
2825 scm_catch_apply. scm_lazy_catch is intended to introduce catch
2826 handlers that run without popping the stack into the dynwind
2829 * throw.h: Added prototypes for scm_catch_apply and
2832 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2834 * root.h (scm_root, scm_set_root): Decouple thread support details
2835 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
2836 SCM_SET_THREAD_LOCAL_DATA.
2838 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
2839 and tortoise scanning loop.
2841 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
2843 * Makefile.in: Rebuild dependencies.
2845 * libguile.h: #include "libguile/print.h" before "smob.h", since
2846 the latter uses the print_state structure.
2848 * throw.c (scm_ithrow): Use the correct variable when checking to
2849 see if a given element of scm_dynwinds is a valid catch.
2851 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
2852 structure, abort; don't just silently ignore the garbage.
2854 * _scm.h: #include "print.h" here, since it seems to be used just
2856 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
2857 strports.c, unif.h: Don't #include "print.h".
2859 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2861 * feature.h (scm_loc_features): Removed external declaration.
2862 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
2864 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2866 * feature.c (scm_init_feature): Added threads feature (needs to be
2867 initialized here, since features doesn't exist when
2868 scm_init_threads is called).
2870 * libguile.h: Added #include "libguile/../threads/threads.h".
2871 (This is a kludge to get thread support working. This should be
2874 * configure.in, acconfig.h: Added flags for thread support.
2876 * scmsigs.c: Define `signal' to be `pthread_signal' if using
2879 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
2880 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
2883 * _scm.h: Added conditional #include "threads.h"
2885 * __scm.h (SCM_ASYNC_TICK): Added call to macro
2886 SCM_THREADS_SWITCHING_CODE.
2888 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
2889 allocate the basic dynamic root object.
2890 (scm_boot_guile): Added call to scm_init_root.
2892 * root.c, root.h: Added root smob.
2893 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
2894 functions: Implements dynamic roots mostly according to spec in
2895 SCM manual. Main difference is that the second argument is a
2896 throw handler rather than an error "thunk".
2898 * root.h: Added declaration of scm_init_root.
2900 * root.c: Added #include "genio.h", #include "smob.h", #include
2901 "pairs.h", #include "throw.h", #include "dynwind.h", #include
2903 (scm_init_root): Added #include "root.x".
2905 * throw.c: Added #include "stackchk.h"
2906 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
2907 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
2908 can be used in scm_call_with_new_root; Added reenabling of stack
2909 checking when catching a throw.
2911 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
2913 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
2915 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
2916 element is not found, as per R4RS.
2918 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2920 * list.c: Doc fixes throughout.
2922 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2924 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
2925 declare the char * to be const. Avoids a warning in rgx.c.
2927 * ports.h: spelling fix.
2929 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
2932 * load.c (scm_sys_try_load_path): throw an error if file not found
2933 (like it says it in NEWS).
2935 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2937 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
2938 PROPS slot to '(), not #f; it's an empty alist.
2940 * throw.h, throw.c: Use SCM_P instead of #if hair.
2942 Remove special support for uncaught throws; see throw.c for
2944 * throw.c (uncaught_throw): New function.
2945 (scm_ithrow): Call uncaught_throw if we don't find a throw
2946 target; don't mess with scm_bad_throw_vcell.
2947 (scm_bad_throw_vcell): Variable deleted.
2948 (scm_init_throw): Don't initialize it.
2950 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
2953 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2955 * numbers.c (scm_istr2int): If the number is short (as most
2956 numbers are), just call scm_small_istr2int to deal with it.
2957 (scm_small_istr2int): New function, created by un-#ifdefing the
2958 non-bignum version of scm_istr2int and renaming it.
2960 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
2962 * load.c (scm_sys_try_load): don't check whether value returned
2963 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
2964 Change the Scheme name from %try-load to primitive-load.
2966 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
2967 Can avoid passing a message, allowing it to be derived in the
2968 error handler (e.g., if we want to throw to the key both from
2971 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
2973 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
2974 references now have a new appearance which is more compact and
2975 also gives a clue about what the target of the reference is.
2976 By setting parameters in the print state, more fancy printing can
2977 be achieved. This is used by the (not yet commited) backtrace
2980 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
2982 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
2985 * print.c: Added #include "struct.h". Removed function
2988 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
2989 scm_iprin1. Removed prototype for scm_prlist.
2991 * arbiters.c (prinarb),
2992 async.c (print_async),
2993 debug.c (prindebugobj, prinmemoized),
2994 eval.c (prinprom, prinmacro),
2995 filesys.c (scm_fd_print, scm_dir_print),
2997 mallocs.c (prinmalloc),
2998 numbers.c, numbers.h (scm_floprint, scm_bigprint),
2999 smob.h (scm_smobfuns),
3000 srcprop.c (prinsrcprops),
3002 unif.c, unif.h (scm_raprin1, rapr1),
3003 variable.c (prin_var): Changed argument `int writing' to
3004 `scm_print_state *pstate'.
3006 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
3007 that it will be called before scm_init_print.
3009 * print.c (scm_prin1): Print states are now allocated when calling
3010 scm_prin1 and then passed around to all printing functions as an
3011 argument. A cache `print_state_pool' enables reuse of print
3013 (scm_make_print_state): New function.
3014 (scm_iprin1): Adaption to print states.
3015 (scm_iprlist): An initial "hare and tortoise" scan brings down
3016 time complexity to O (depth * N). (Better time complexity will be
3017 achieved when the printing code is completely rewritten.)
3019 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3021 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
3022 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
3023 it gets done whether or not the cache variable has a value.
3025 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3027 Distinguish #f and ().
3028 * __scm.h: #undef SICP.
3029 * pairs.h (SCM_EOL): Delete this definition, equating it with
3031 * tags.h (SCM_EOL): Give it a new definition here; I think I found
3032 the value it used to have. Doc fixes, too.
3034 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
3036 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
3037 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
3038 Lord's implementation of structs, allowing for tail arrays as
3039 described in the manual. Also fixed some bugs. (Both the interface
3040 and the implementation should be improved.)
3042 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
3044 * print.c, print.h: Closures now print like #<procedure foo (x)>.
3045 People who whish to see the source can do `(print-enable 'source)'.
3046 Removed #ifdef DEBUG_EXTENSIONS.
3048 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
3050 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
3051 integer (assuming for now accepting an integer is a good thing).
3053 * error.c, fports.c: replace use of %S in lgh_error args with %s.
3054 %S will be used instead for write'ing arguments.
3056 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
3057 asserts. fix a few other asserts.
3058 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
3059 scm_uniform_vector_ref, scm_array_set_x,
3060 scm_dimensions_to_unform_array): change args in
3061 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
3062 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
3063 scm_substring_fill_x): likewise.
3064 gsubr.c (scm_gsubr_apply): likewise.
3065 eval.c (SCM_APPLY): likewise.
3067 * eval.c (4 places): replace scm_everr with lgh_error or
3070 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
3071 scm_memory_error): new procedures.
3072 scm_everr: deleted. can use scm_wta, dropping first two args.
3073 scm_error: convert NULL subr to SCM_BOOL_F.
3075 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
3078 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
3081 * error.c, error.h: new error keys: scm_arg_type_key,
3082 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
3084 scm_wta: reimplement using lgh_error instead of scm_everr.
3086 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
3088 * gdbint.c: scm_lread now has one more argument.
3090 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
3091 scm_port_\1; Added mutator scm_set_port_filename_x (used when
3092 loading source from non-file ports, which, e. g., happens when
3093 using the Emacs interface).
3095 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
3098 * read.c: Added code for recording of positions of source code
3099 expressions; New functions: recsexpr, scm_lreadrecparen;
3100 _scm_make_srcprops --> scm_make_srcprops
3101 (scm_flush_ws): Removed updating of positions counters. This work
3102 is already done by scm_gen_getc
3104 * read.h: Added prototype for scm_lreadrecparen
3106 * print.c: Added #include "alist.h"
3108 * eval.c: Added #include "hash.h"
3110 * eq.c: Added #include "ramap.h"
3112 * options.c: Documentation fixes.
3114 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
3115 (scm_init_srcprop): Adjusted size of initial source-whash. Name
3116 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
3117 --> scm_make_srcprops
3119 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
3120 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
3121 function calls in the definition of the whash access macros.
3123 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
3125 * init.c (scm_boot_guile): Add level of indirection to
3126 scm_boot_guile_1() to ensure that stack base pointer is properly
3127 initialized. There was no guarantee that variable i was the
3128 highest/lowest variable on stack (i.e. the call frame of
3129 scm_boot_guile was not completely protected from gc).
3131 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
3133 * ports.h (scm_port_table): put back file_name, it will be used to
3134 support debugging. Undo related changes in fports.c, ioext.c,
3137 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
3139 * ports.h (scm_port_table): remove file_name member for now, it seems
3141 * fports.c (scm_open_file): don't set file_name in PTAB.
3142 (prinfport): don't use file_name in PTAB.
3143 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
3144 * ports.c (scm_add_to_port_table): don't intialize file_name.
3145 (scm_port_file_name): remove for now.
3146 * gc.c (scm_gc_mark): don't mark PTAB file_name.
3148 * fports.h (scm_mkfile): prototype deleted.
3149 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
3151 * debug.c, unif.c: use scm_out_of_range instead of
3152 wta for range errors (ASSERT still needs work).
3154 * error.c, error.h (scm_out_of_range): new procedure.
3156 * error.c, error.h (scm_out_of_range_key): new key.
3158 * posix.c (scm_sync): #else was missing.
3160 * error.c, error.h: append _key to names scm_num_overflow and
3163 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
3164 of consing an empty list.
3165 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
3166 of macros, saves code and string space.
3167 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
3168 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
3169 lower case. Rename scm_syserror_m to scm_syserror_msg.
3170 error.h: prototypes for new procedures.
3172 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
3174 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
3176 * error.c, error.h: setup scm_num_overflow key.
3178 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
3179 Remove definition of SCM_OVSCM_FLOW.
3181 * fports.c (scm_open_file): use SCM_SYSERROR_M.
3183 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
3184 explicit message and args.
3186 * error.c, error.h, __scm.h: change system_error_sym to
3189 * error.c (system_error_sym): remove leading %% from the Scheme name
3192 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
3194 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3196 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
3197 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
3198 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
3199 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
3200 renamed. (These were introduced by unsupervised name
3203 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3205 * print.c: Added code for detection of circular references during
3206 printing. (init_ref_stack, grow_ref_stack): New functions. Added
3207 a hook for printing of closures (accessible via print options).
3208 This leads to a split of calls to scm_iprin1 into two classes:
3209 elementary print operations (e. g. the code which prints a smob)
3210 still use scm_iprin1 while top level calls (like scm_display) use
3211 scm_prin1. scm_prin1 begins by clearing the data structure used
3212 to record reference information.
3214 * print.h: Added declarations of scm_prin1 and scm_prlist.
3216 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
3218 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
3220 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
3222 * error.c (err_head): scm_iprin1 --> scm_prin1
3224 * debug.c: Adjusted header comment.
3228 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
3230 * strerror.c: Doc fix.
3232 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3234 * gdbint.c (gdb_read): Now possible to run during GC.
3235 (unmark_port, remark_port): New functions.
3237 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
3239 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
3240 of allocating a new string object. Also, increase size by
3241 the factor 2 instead of 1.5.
3243 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
3245 * __scm.h (SCM_P): Corrected to run under traditional C.
3247 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
3250 * async.c: Calls to scm_sysintern corrected.
3252 * async.h (scm_async_clock): Redundant declaration removed.
3254 * continuations.c (scm_dynthrow): Redundant declaration removed.
3256 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
3257 Definition typos corrected.
3259 * debug.h: Missing declarations of functions in debug.c added
3262 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
3263 Missing declarations to functions in eval.c added.
3265 * filesys.c: Possibly uninitialized variable rv.
3267 * gc.h (scm_object_addr, scm_unhash_name): Missing
3268 declarations of functions defined in gc.c added.
3270 * genio.c: Possible typos str_data -> wstr_data. ???
3272 * genio.c: Possibly unintended shadowing of local variable
3273 `int c' (gotos out of scope of inner `c'). ???
3275 * init.c: Uninitialized `SCM last' may be used.
3277 * ioext.h: (scm_sys_isatty_p): Typo.
3279 * list.h (scm_list_head): Missing prototype for function in
3282 * numbers.c (scm_two_doubles): Changed from extern to static
3283 (is used only within numbers.c).
3285 * numbers.h: Repeated declarations removed.
3287 * ports.h (scm_close_all_ports_except): Declaration for the
3288 function defined in ports.c added.
3290 * posix.h: Missing declarations added.
3292 * procs.h (scm_make_subr_opt): Missing declaration added.
3294 * socket.h (scm_sys_gethost): Missing declaration added.
3296 * socket.h: Redundant declarations removed (they are in fdsocket.h).
3298 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
3299 Missing declarations added.
3301 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
3303 * struct.c: Uninitialized variable `SCM answer' may be used.
3305 * unif.c (l2ra): Declaration prototype.
3307 * unif.c (scm_array_equal_p): Dummy definition removed (it is
3308 defined in ramap.c).
3310 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
3311 Redundant declarations removed (they are in ramap.h).
3313 * variable.h (scm_make_udvariable,
3314 scm_make_undefined_variable): Declaration corrected to
3315 correspond variable.c.
3317 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
3318 Missing declarations added.
3320 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
3322 * Makefile.in (distclean): Don't forget to delete fd.h.
3324 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3326 * fd.h.in, tags.h: Trivial cleanups.
3328 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
3329 marksweep.h just declared functions from gc.c.
3330 * gc.h, libguile.h: Don't #include "marksweep.h".
3331 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
3332 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
3333 dependencies updated.
3335 * libguile.h: Don't #include "files.h"; it's been deleted.
3337 * files.c (scm_sys_delete_file): Moved to filesys.c.
3338 File is now empty; deleted.
3340 * filesys.c: scm_sys_delete_file is now here. Remove
3341 #if's; they seem to rely on remnants of an old portability
3342 regimen. If the problems come up again, solve them properly,
3343 using autoconf. Specifically: Don't test M_SYSV, and #define
3344 remove to be unlink if it's #defined; don't use remove just
3345 because HAVE_STDC_HEADERS is #defined.
3346 * filesys.h: Add declarations for scm_sys_delete_file.
3347 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
3348 files.o, files.h, files.c, and files.x.
3349 * init.c: Don't #include "files.h", and don't call scm_init_files.
3351 Use SCM_P instead of PROTO; the latter intrudes on the user's
3353 * params.h: Deleted; definition of SCM_P moved to...
3354 * __scm.h: ... here, where it replaces PROTO macro.
3355 * libguile.h, smob.h: Don't #include "params.h".
3356 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
3357 smob.h: Fix prototypes accordingly.
3358 * Makefile.in: Update dependencies.
3359 (inner_h_files): Remove params.h.
3361 * gc.c: #include "gc.h"; every module should include its header,
3362 to let the compiler cross-check the declarations against the
3365 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
3366 simpos.h: #include "libguile/__scm.h".
3368 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
3370 * init.c: Don't forget to #include smob.h and init.h.
3371 * Makefile.in: Dependencies updated.
3373 * smob.h: Use PROTO instead of #if __STDC__.
3375 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
3377 * __scm.h: Doc fixes.
3379 * __scm.h, libguile.h: Use "quotes" in the #includes, not
3380 <angles>; this allows `make depends' to work properly.
3382 * libguile.h: #include smob.h and pairs.h before the others; they
3383 define typedefs used by other headers.
3385 C files should #include only the header files they need, not
3386 libguile.h (which #includes all the header files); the pointless
3387 recompilation was wasting my time.
3388 * Makefile.in (all .o dependency lists): Regenerated.
3389 * libguile.h: Don't try to get a definition for size_t here...
3390 * __scm.h: Do it here.
3391 * _scm.h: Since this is the internal libguile header, put things
3392 here that all (or a majority) of the libguile files will want.
3393 Don't #include <libguile.h> here; that generates dependencies on
3394 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
3395 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
3396 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

3432 "unif.h", "throw.h", "tag.h", "symbols.h", "struct.h",

3493 * weaks.c: Get "weaks.h".
3495 * stackchk.h: #include "libguile/debug.h",
3497 * print.h, read.h: #include "options.h", since everyone who uses
3498 either of these files will need that.
3500 * smob.h: #include "ports.h", "genio.h", and "print.h", since
3501 anyone who uses this file will need them to define the smob
3502 printing functions. Also, get markers.h, since people will need
3503 to #define the mark functions.
3505 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
3506 * ports.h: ... to here.
3508 * ports.h (scm_port_table_size): Explicitly give type as 'int';
3509 don't rely on archaic C default type rules.
3511 * fports.h: #include "libguile/ports.h", since you need that in
3512 order to parse this.
3514 * genio.h: #include "libguile/print.h", because you need that to
3515 parse this; don't bother #including "ports.h", since print.h gets
3518 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
3520 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
3521 this; it's now a reference to an element of *scm_root.
3523 * debug.h: Don't #include "options.h"; the compiler won't be able
3524 to find that once the headers are installed; instead, #include
3525 "libguile/options.h".
3526 * gc.h: Same, with marksweep.h.
3527 * mbstrings.h: Same, with symbols.h.
3528 * scmhob.h: Same, with _scm.h.
3529 * smob.h: Same, with params.h.
3531 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
3532 C files; there's no need for this, and it forces recompilations
3535 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
3537 * error.c (scm_error): declare scm_error_callback.
3539 * error.h: prototype for scm_error_callback.
3541 * __scm.h: define lgh_error.
3542 (SCM_SYSERROR): redefine using lgh_error.
3544 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
3546 * error.c (scm_error): new procedure.
3548 * error.h: prototype for scm_error.
3550 * Makefile.in (install): install scmconfig.h from the current
3551 directory, not $(srcdir).
3553 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
3555 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3556 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3557 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
3558 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
3559 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
3560 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
3561 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
3562 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
3563 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3564 vports.h, weaks.h: #include "libguile/__scm.h", not
3565 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
3566 dependencies are within libguile properly.
3568 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
3570 * Makefile.in (.c.x): Simplify; there's no need to run this rule
3571 when scmconfig.h doesn't exist.
3573 * load.c (scm_sys_try_load): Correct spelling.
3575 * feature.c (scm_loc_features): Make this static.
3577 * Makefile.in (libpath.h): Omit trailing slash from path. We
3578 shouldn't require it of users, so why put it here?
3580 Move code to initialize and search %load-path from ice-9 to C
3581 code, so we can use the load-path to find the ice-9 boot code;
3582 this makes it easier to run Guile without installing it. See
3583 corresponding changes in guile/Makefile.in.
3584 * feature.c: Move stuff concerned with the load path to load.c.
3585 (scm_compiled_library_path): Deleted.
3586 Don't #include libpath.h here.
3587 * feature.h: Don't mention scm_compiled_library_path.
3588 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
3589 <sys/stat.h>, and <unistd.h> (if present).
3590 (R_OK): #define if the system hasn't deigned to.
3591 (scm_loc_load_path): New variable.
3592 (scm_init_load_path, scm_sys_search_load_path,
3593 scm_sys_try_load_path): New functions.
3594 (scm_init_load): Initialize scm_loc_load_path to point to the
3595 value cell of the Scheme %load-path variable.
3596 * load.h: Add declarations for scm_sys_search_load_path,
3597 scm_sys_try_load_path.
3598 * init.c: Call scm_init_load_path.
3599 * Makefile.in (feature.o, load.o): Dependencies updated.
3601 * load.c, load.h: Rewrite using PROTO macro.
3603 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3605 * gc.c (scm_cellp): New function: C predicate to determine if an
3606 SCM value can be regarded as a pointer to a cell on the heap.
3608 * gc.h: Added declaration of scm_cellp.
3610 * gdb_interface.h: New file: The GDB interface header from the GDB
3613 * gdbint.c: New file: GDB interface.
3615 * gdbint.h: New file: GDB interface.
3617 * libguile.h: Added #include <libguile/gdbint.h>.
3619 * init.c (scm_boot_guile): Added scm_init_gdbint.
3621 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
3622 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
3623 found if object files and source are kept separate).
3625 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
3627 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
3629 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
3631 * configure.in: Don't substitute the values of TCL_SRC_DIR and
3632 TK_SRC_DIR; they're not relevant any more.
3634 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
3635 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
3637 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
3639 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
3640 search path, so we can find the <libguile/MUMBLE.h> headers.
3642 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
3644 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
3645 implicit in the .c.o rule.
3646 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
3649 Put the library path in a header file, instead of passing it on
3650 the command line in every compilation.
3651 * Makefile.in (libpath.h): New target.
3652 (feature.o): Depend on libpath.h.
3653 (clean): Delete libpath.h.
3654 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
3655 * feature.c: ... #include "libpath.h" here.
3656 * .cvsignore: Ignore libpath.h.
3658 Don't install the unwashed masses of Guile header files in the
3659 main #include path; put most of them in a subdirectory called
3660 'libguile'. This avoids naming conflicts between Guile header
3661 files and system header files (of which there were a few).
3662 * Makefile.in (pkgincludedir): Deleted.
3663 (innerincludedir): New variable; this and $(includedir) are enough.
3664 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
3665 (installed_h_files): Divide this up. Now this variable lists
3666 those header files which should go into $(includedir) (i.e. appear
3667 directly in the #include path), and ...
3668 (inner_h_files): ... this new variable says which files appear in
3669 a subdirectory, and are referred to as <libguile/mumble.h>.
3670 (h_files): List them both.
3671 (install): Create innerincludedir, not pkgincludedir. Put
3672 the installed_h_files and inner_h_files in their proper places.
3673 (uninstall): Corresponding changes.
3674 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3675 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3676 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
3677 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
3678 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
3679 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
3680 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
3681 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
3682 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3683 vports.h, weaks.h: Find __scm.h in its new location.
3684 * __scm.h: Find scmconfig.h and tags.h in their new locations
3685 (they're both "inner" files).
3687 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
3689 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
3691 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
3693 * posix.c: Doc fixes.
3695 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
3697 * socket.c: Don't include a prototype for inet_aton; just use a
3698 K&R style declaration, to avoid warnings but minimize the chance
3699 of conflicts with the system.
3701 On NextStep, <utime.h> doesn't define struct utime, unless we
3702 #define _POSIX_SOURCE before #including it.
3703 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
3704 * acconfig.h: New comment text for above CPP symbol.
3705 * configure.in: Call it.
3706 * posix.c: #define _POSIX_SOURCE if it seems necessary.
3708 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
3710 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
3711 testing for __EMX__.
3713 * posix.c: #include <libc.h>, if it exists.
3715 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
3716 don't even know if the latter exists.
3718 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
3719 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
3720 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
3722 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
3724 (scm_init_posix): Use them when initializing the Scheme constants
3727 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3729 * Makefile.in (libdir, includedir, bindir): Use the
3730 autoconf-supplied values, instead of deriving them ourselves.
3731 (pkgincludedir, datadir, pkgdatadir): New variables.
3732 (install, uninstall): Put the header files in a special
3733 subdirectory, not in the main search path.
3735 * Makefile.in (ALL_CFLAGS): Provide the proper value for
3736 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
3738 * Makefile.in (IMPLPATH): Deleted; never used.
3740 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
3741 on the Tcl/Tk source any more.
3742 (INCLUDE_CFLAGS): Remove references to the above.
3744 * Makefile.in (version.o): Corrected dependencies.
3746 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
3748 * libguile.h: #include "version.h"
3750 * init.c (scm_boot_guile): Call scm_init_version.
3751 * gscm.c (gscm_run_scm): Call scm_init_version.
3753 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
3754 GUILE_VERSION): AC_DEFINE these.
3755 (acconfig.h): #undef the above symbols.
3757 * Makefile.in (libobjs): Add version.o.
3758 (installed_h_files): Add version.h.
3759 (c_files): Add version.c.
3760 (gen_c_files): Add version.x.
3761 (version.o): New rule.
3762 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,

3772 weaks.o): Add version.h to dependency lists.
3773 (markers.o): Remove duplicate rule.
3775 * version.h: New file.
3777 * version.c: New file.

3781 * symbols.c (scm_strhash): scm_downcase is now a function, not an
3782 array; use it appropriately. Since GCC is quite happy to
3783 subscript functions, it never warned us about this; we should use
3784 -Wpointer-arith in the future. I guess we never tested
3787 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3789 * socket.c: Doc and copyright fixes.
3791 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3793 * debug.c: Fixed and improved gdb support.
3795 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3797 * socket.c: Added declaration of inet_aton to avoid compiler
3798 warning. (Hope this solution is correct.)
3800 * stime.c: Added declaration of ftime. (This is missing in
3803 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
3805 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3807 * Makefile.in (c_files): add strerror.c.
3809 * strerror.c: new file from Emacs' sysdep.c.
3810 maybe configure should also check for sys_errlist.
3812 * configure.in (AC_REPLACE_FUNCS): add strerror.
3814 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3816 * debug.c (scm_init_debug): Added initialization for
3817 scm_evaluator_traps.
3819 * debug.h, debug.c: Various name changes.
3820 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
3821 "debug-options-interface". See commentary in options.c.
3823 * options.h, options.c: Options now have documentation strings.
3824 Also added a long explanatory commentary.
3826 * eval.c, print.h, print.c, read.h, read.c: Modifications to
3829 * gscm.c, init.c, root.c, throw.c: Bug fixes:
3830 last_debug_info_frame is now updated in all cases.
3832 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
3835 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3837 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
3838 Added option STACK_CHECKING.
3840 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3842 * Makefile.in: Added {debug,options,srcprop}.{h,c}
3844 * __scm.h: Removed symbols for debugging support.
3846 * acconfig.h: Added symbols for debugging support.
3848 * configure.in: Added user option for debugging support.
3849 --enable-debug will include the debugging code into libguile.a.
3851 * continuations.c (scm_make_cont): Enlarged the #if 0 around
3852 scm_relocate_chunk_to_heap.
3854 * debug.c: New file: low-level debugging support. It also
3855 includes support for debugging with gdb. (The extensions to gdb
3856 are written by Per Bothner at Cygnus.)
3858 * debug.h: New file: low-level debugging support.
3860 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
3861 argument pairs. Extensive modifications to the debugging
3862 evaluator. Added "SECTION:" commentaries to clarify what happens
3863 when, during double compilation. Renamed EVALIMP --> EVALIM.
3864 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
3865 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
3866 the beginning of the file. New procedure: scm_unmemocopy.
3867 Added some global state variables needed by the debugging
3868 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
3869 check_entry, check_apply, check_exit, debug_options and
3870 evaluator_traps. New acro: undefine.
3872 * eval.h: Renamed EVAL --> XEVAL.
3874 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
3875 --> scm_make_weak_key_hash_table.
3877 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
3878 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
3880 * libguile.h: Conditionally include debug.h
3882 * objprop.c (scm_object_properties, scm_set_object_properties_x):
3883 scm_object_properties shouldn't return handle. `handle' now gets
3884 initialized in scm_set_object_properties_x. scm_object_properties
3885 doesn't any longer create an entry in scm_object_whash.
3887 * options.c: New file: handling of run time options.
3889 * options.h: New file: handling of run time options.
3891 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
3893 * print.c: New procedure: scm_print_options
3895 * print.h: Defines for print options.
3897 * read.c: New procedure: scm_read_options
3899 * read.h: Defines for reader options.
3901 * root.h: Added scm_source_whash among scm_sys_protects.
3903 * srcprop.c: New file: source properties.
3905 * srcprop.h: New file: source properties.
3907 * throw.c (jbsmob): Jump buffers are now correctly allocated.
3908 (Bug found by A. Green.)
3910 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3912 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3914 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
3916 * libguile.h: #include "objprop.h"; I guess this was forgotten.
3918 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
3919 and should be called by the final client.
3921 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
3923 * gc.h: Use the PROTO macro when declaring functions.
3924 * gc.c: Use the PROTO macro when declaring static functions.
3925 Remove the CPP hair around function definitions.
3927 * gc.c (scm_init_storage): Initialize scm_asyncs.
3929 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
3930 preprocessor symbol; "__scm.h" is where it might get #defined.
3931 * __scm.h: Similar: #include <scmconfig.h> before testing
3934 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
3936 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
3938 * init.c (scm_boot_guile): Add init_func argument; call
3939 (*init_func) instead of calling scm_appinit; it's ucky to
3940 hard-code names for the user's procedures.
3941 * init.h (scm_boot_guile): Adjust declaration.
3943 * __scm.h (PROTO): New macro, for declaring functions with
3946 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
3947 eliminate all the __STDC__ conditionals.
3948 (scm_boot_guile): Add declaration.
3949 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
3950 Remove __STDC__ conditionals around function definitions; the
3951 declarations in init.h will provide the same information, more
3954 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
3955 complain about it in the error message; the error message is
3956 adequate without that note, and there's nothing the user can do
3959 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
3961 * Makefile.in (ancillary): Drop def.sed.
3963 * posix.c (scm_init_posix): Use numeric values, rather than
3964 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
3965 F_OK. The symbols aren't available on some systems, and I'm
3966 pretty sure their values are fixed by common widespread practice.
3967 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
3969 More functions unavailable on some systems.
3970 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
3971 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
3973 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3974 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
3975 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
3976 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
3977 stub that signals an error as the #else.
3979 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
3981 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
3983 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
3985 * unif.c: include ramap.h.
3987 * read.c (endif): case_insensative_p renamed case_insensitive_p.
3989 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
3991 * ports.c: include sys/ioctl.h.
3993 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
3995 * configure.in: check for sys/ioctl.h.
3997 * ports.c: include <malloc.h> not "malloc.h".
3999 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
4001 * fports.c: remove ttyname and tmpnam declarations.
4003 * posix.c: fewer ttyname declarations.
4005 * fports.c: include <string.h> not "string.h".
4007 * init.c, ioext.c: include string.h and unistd.h.
4009 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
4011 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
4012 genio.c, simpos.c, vports.c: include string.h.
4014 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
4016 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
4018 (scm_addr_buffer_size): change type from scm_sizet to int.
4019 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
4020 from scm_sizet to int.
4022 * error.c: include unistd.h.
4024 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
4027 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
4029 * __scm.hd, def.sed: deleted.
4031 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
4033 Changes for NeXT, suggested by Robert Brown.
4034 * configure.in: Call AC_TYPE_MODE_T.
4035 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
4036 NeXT. Put header file list in alphabetical order.
4037 * configure, scmconfig.h.in: Regenerated.
4038 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
4040 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
4043 * acconfig.h: New file, providing documentation for the CPP
4044 symbols defined in configure.in
4045 * acconfig-1.5.h: Removed; superceded by the above.
4047 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
4049 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
4051 * fports.c (scm_open_file): don't return #f, throw error.
4053 * ioext.c (fileno): renamed from %fileno.
4054 (soft-fileno): deleted.
4056 * ports.c (scm_port_revealed): don't need to check for -1 from
4058 (scm_set_port_revealed_x): return unspecified, not #f.
4060 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
4062 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
4064 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
4066 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
4068 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4070 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
4071 This is necessary on Ultrix, and doesn't hurt portability.
4073 * Makefile.in (dist-dir): New target, implementing a new dist system.
4074 (installed_h_files): Put in alphabetical order.
4075 Remove duplicate entries for markers.h and unif.h.
4076 (c_files): Remove duplicate entries for markers.c.
4077 (ancillary): Renamed from anillery; all uses changed. Remove
4078 PLUGIN; it's a directory, and needs special treatment in dist-dir.
4079 Remove all the ../doc/* files; doc/Makefile.in handles that.
4081 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
4083 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
4084 every if must have an else, or else the whole command has a
4085 non-zero exit code whenever the if's condition is false.
4087 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
4089 * posix.c: include string.h.
4091 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4093 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
4096 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
4097 Remove leading % from scheme names.
4098 Do not return error values, call SCM_SYSERROR or similar.
4100 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
4102 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
4104 * struct.c (scm_init_struct): new file.
4106 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
4108 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
4109 (scm_list_head): added list-head for rapidly chopping argument
4110 lists off of longer lists (and similar).
4112 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
4114 * objprop.c (scm_object_property): assq the cdr of the whash
4115 handle for obj, not the handle itself.
4117 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
4119 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
4120 weak hash tables last of all marking to avoid an obscure gc bug.
4121 WARNING: circular lists stored in a weak hash table will hose us.
4123 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
4125 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
4126 new functions similar to scm_substring_move_left_x and
4127 scm_substring_move_right_x.
4129 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
4131 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
4134 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
4136 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
4138 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
4140 * strports.c (scm_strprint_obj): convenience function. C for
4141 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
4143 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
4144 removed to a separate library
4146 * init.c (scm_boot_guile): copied from guile-tcl.c.
4147 Initialization specific to tcl interpreters removed.
4149 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
4151 * ports.c (scm_ports_prehistory): size malloced here doesn't
4152 matter so long as it is non-0 (got rid of "* 4").
4154 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
4156 * gscm.h: gscm_mkarray eliminated (presumably was not being used
4157 since its definition was bogus).
4159 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
4161 * mallocs.[ch]: back again (for rx at least).
4163 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
4165 * ports.c: removed functions relating to the mapping between ports
4166 and descriptors. (That stuff is unix-specific and should be collected
4167 in a separate library).
4169 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
4170 (Tom Mckay@avanticorp.com)
4172 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
4174 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
4175 handled correctly (SCM_FREEP was applied to them) -- test for
4176 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
4177 being overwritten with #f. (brown@grettir.bibliotech.com)
4179 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
4181 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs

4191 * list.c (scm_last_pair): map '()=>'()
4193 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>

4196 Generalized assoc and hash-table functions.
4197 Factored pairs.c into multiple files.
4199 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
4201 * gscm.c (gscm_run_scm): got rid of objprop.
4203 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
4205 * genio.c (scm_getc):
4206 NOTE: fgetc may not be interruptable.
4208 * procprop.c (scm_stand_in_scm_proc):
4209 NOTE: don't use a alist here.
4210 (scm_set_procedure_properties_x): fix type checking throughout this file.
4212 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
4214 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
4215 after freeing part of the port table.
4217 Thu Feb 29 16:21:17 1996 Tom Lord <lord@beehive>
4219 * strports.c (scm_mkstrport):
4220 * vports.c (scm_make_soft_port): allocate a port table entry
4221 (possibly triggering gc) before setting the tag of the corresponding
4224 * pairs.c (scm_delq_x): never throw an error.
4226 * vectors.c (scm_make_vector): made the default vector fill argument
4227 into '() (much more useful than the previous value, "#unspecified")
4229 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
4231 * ports.c (scm_add_to_port_table): Added fields
4232 to port table entries: file_name, line_num, col.
4233 Update these in open_file, gen_getc and gen_ungetc.
4234 Added procedures to access those fields.
4236 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
4238 * procs.c (scm_make_subr_opt): new entry point for making
4241 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
4243 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
4245 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
4247 * numbers.c (scm_exact_p): This function no longer
4248 implements "integer?".
4250 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
4252 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
4253 (scm_gc_stats): return an assoc of useful data. Replaces "room"
4254 and the stats reporting formerlly built into repl.
4256 * repl.[ch]: removed.
4257 GC statistics keeping moved to gc.c.
4258 Other statistics keeping can be done from Scheme.
4259 REPLS are now written in Scheme.
4261 Wed Feb 21 10:28:53 1996 Tom Lord <lord@beehive>
4263 * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky
4264 conservatively marked objects).
4266 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
4268 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
4270 * feature.c (scm_compiled_library_path): moved here from repl.c.
4271 This file is for stuff relating specifically to Scheme libraries
4274 * eval.c (scm_m_define): don't give warning about redefinition, don't
4277 NOTE: this should throw a resumable exception with parameters --
4278 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
4280 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
4282 * error.c: scm_warn eliminated.
4284 * read.c (scm_lreadr): extra right paren gets an error, not a warning.
4286 * repl.c, marksweep.c, gc.c (various):
4287 lose exit_report, growth_mon.
4289 * gscm.c: got rid of verbosity functions.
4291 Tue Feb 20 00:19:10 1996 Tom Lord <lord@beehive>
4293 * throw.c (scm_ithrow): guard against the bad-throw hook changing
4294 between the call to procedurep and use.
4296 * error.c (scm_everr):
4298 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
4301 * strports.c: don't reveal the port's string to the caller
4302 because it changes size.
4304 (stputc stwrite): check/change the strings length with interrupts
4307 * objprop.c (scm_set_object_property_x &c): use the generic
4308 hashing functions and be threadsafe.
4310 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
4311 (per suggestion jaffer@gnu.ai.mit.edu).
4313 * mbstrings.c (scm_multi_byte_string): guard against argument list
4316 * strings.c (scm_make_string): loop cleanup
4318 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer
4321 * weaks.c (scm_weak_vector): guard against argument list
4324 * variable.c (scm_builtin_variable): check for/make a built-in
4327 * vectors.c (scm_vector): while filling the new array,

4344 initialization to fix a race condition.
4346 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

4370 set the multi_byte flag correctly in symbols. This is wrong.
4371 intern_obbary_soft and msymbolize should take an extra parameter.
4372 Also, weird multibyte symbols don't print correctly.
4373 The weird symbol syntax is also a bit bogus (emacs doesn't quite
