307 This patch unifies the formerly distinct ssymbol and msymbol types
308 to a common symbol type scm_tc7_symbol. The representation of the
309 new symbol type uses a double cell with the following layout:
310 <type/length, chars, raw_hash, prop-pair>, where the car of
311 prop-pair holds the symbol's function property and the cdr of
312 prop-pair holds the symbol's other properties. In the long run,
313 these properties will be removed. Then, the generic property
314 functions will be uses.

330 is not used any more.

334 (scm_intern_obarray_soft): Made softness parameter unsigned.
336 (scm_string_hash): New function with the same functionality as
337 scm_strhash had before, except that the hash value is not adjusted
338 to a hash table size. Instead, the 'raw' hash value is returned.
340 * symbols.c (duplicate_string): New static convenience function.
342 (scm_sym2vcell, scm_sym2ovcell_soft, scm_intern_obarray_soft):
343 Renamed local variable from scm_hash to hash.

351 (scm_intern_symbol, scm_unintern_symbol): Use scm_string_hash to
352 determine the hash values.

548 `make-struct-layout'.)
550 * stacks.c (scm_init_stacks): Pass a string, not a layout object,
551 to scm_make_vtable_vtable. (Thanks to Dale P. Smith.)
553 * struct.c (scm_make_struct_layout): Removed reference to
554 "read-only string" in comment; Check that argument is a string.
555 (scm_make_vtable_vtable): Check that argument is a string.
557 * environments.c (scm_init_environments): All internal includes in
558 libguile must use the prefix "libguile/" in path names since inly
559 the top-level source directory is on the include list. (That, in
560 turn, is because we want to distinguish between system header
561 files and hedares files internal to libguile.)
563 * strings.c (scm_make_shared_substring, scm_read_only_string_p):
565 (scm_string_length, scm_string_ref, scm_substring,
566 scm_string_append): Don't accept symbols as arguments (R5RS).
568 2000-08-25 Neil Jerram <neil@ossau.uklinux.net>
570 * ports.c (scm_set_port_column_x): Fix docstring so that it
571 mentions set-port-line! rather than set-port-column! twice.
573 * guardians.c (scm_make_guardian): Remove spurious . from doc string.
575 2000-08-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
577 * Makefile.am: Added all necessary environments.* files.
579 * init.c: Include environments.h.
581 (scm_boot_guile_1): Initialize the environments.
583 * environments.[ch]: Added. Most of the credit for these files
584 goes to Jost Boekemeier.
586 2000-08-25 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
588 * procprop.c: #include "libguile/smob.h"; handle applicable smobs.
590 2000-08-24 Keisuke Nishida <kxn30@po.cwru.edu>
592 * smob.h (scm_smob_descriptor): Added `apply' and `gsubr_type'.
593 * smob.c (scm_make_smob_type): Initialize `apply' and `gsubr_type'.
594 (scm_set_smob_apply): New function.
595 (scm_smob_apply_0, scm_smob_apply_1, scm_smob_apply_2,
596 scm_smob_apply_3): New functions.
597 * eval.c (SCM_CEVAL, SCM_APPLY): Added dispatch for applicable smobs.
598 * procs.c (scm_procedure_p): Check applicable smobs.
600 2000-08-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
602 * Makefile.am (BUILT_SOURCES): Experimentally added scmconfig.h
603 also here. (This is supposed to make sure that scmconfig.h is
604 built before all sources in order to prevent that everything has
605 to be rebuilt again. Hope it works---I'm just guessing. :)
607 * fluids.c (scm_fluid_set_x): Return SCM_UNSPECIFIED.
609 2000-08-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
611 * gc.c (scm_gc_mark): Don't use GUILE_DEBUG flag to compile in
612 extra tests. (GUILE_DEBUG is only supposed to make extra
613 debugging functions available.)
615 2000-08-21 Michael Livshin <mlivshin@bigfoot.com>
617 * gc.h (SCM_GC_CARD_N_CELLS): change to be a nice non-confusing
620 2000-08-19 Michael Livshin <mlivshin@bigfoot.com>
622 * gc.c (scm_gc_sweep): added a `continue' statement that have
623 fallen through the cracks in the merge. thanks to Shuji Narazaki!
625 * gc.h: removed some stuff that broke compilation for people and
626 wasn't actually needed anyway.
628 2000-08-18 Neil Jerram <neil@ossau.uklinux.net>
630 * filesys.c (scm_fcntl): Docstring fix - missing newlines inserted.
632 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_sethost,
633 scm_setnet, setproto, setserv): Argument names changed to match
636 * feature.c (scm_program_arguments): New docstring.
638 * simpos.c (scm_getenv): Reflow docstring.
640 * eq.c (scm_eq_p, scm_eqv_p, scm_equal_p): Add texinfo markup to
643 * chars.c (scm_char*): Docstring fixes - texinfo markup.
645 2000-08-18 Neil Jerram <neil@ossau.uklinux.net>
647 * boolean.c (scm_not, scm_boolean_p): Docstring fixes - add
648 texinfo markup and remove trailing newlines.
650 2000-08-17 Michael Livshin <mlivshin@bigfoot.com>
652 this changes the Guile GC to use cards (aka "chunklets").
653 (most of the ideas and some of the code are by Greg Harvey, though
654 the code is probably unrecognizable now. the original chunklet
655 proposal, way back, is by Dale Jordan).
657 * tags.h: (SCM_GCTYPE16, SCM_GCCDR, SCM_GC[8]MARKP,
658 SCM_SETGC[8]MARK, SCM_CLRGC[8]MARK): moved from here into gc.h.
659 some (most) of these are probably going to be deprecated.
661 * gc.h (SCM_MARKEDP): simplified, there are no different mark bit
663 (SCM_GC_CARD_*, SCM_C_BVEC_*): lots of new macros to deal with
664 cards and bvecs (bit-vectors).
666 * gc.c: (scm_default_init_heap_size_*): defined to take cards into
667 account, but keeping more or less the same values as previously.
668 added some simple helper macros.
669 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK): defined to take cards
671 (BVEC_*, scm_mark_space_t, current_mark_space, mark_space_ptr,
672 current_mark_space_offset, mark_space_head, get_bvec,
673 clear_mark_space): new functions and supporting variables, types
674 and macros that implement mark space management.
675 (scm_igc): clear the mark space (all of it) before beginning the
677 (scm_gc_mark): changed the tests for rogue cells, much simplified
678 throughout (no different mark bit locations to worry about now).
679 (scm_mark_locations): don't consider card header cells.
681 (scm_gc_sweep): simplified.
682 (init_heap_seg): changed to take cards into account.
684 2000-08-16 Michael Livshin <mlivshin@bigfoot.com>
686 * stime.c (scm_c_get_internal_run_time): new function, same as
687 scm_get_internal_run_time but returns a long. it's used by the GC
688 for timekeeping, since with scm_get_internal_run_time there is a
689 (extremely theoretical) possibility of consing.
690 (scm_get_internal_run_time): redefined in terms of
691 scm_c_get_internal_run_time.
693 * stime.h: added prototype for scm_c_get_internal_run_time.
695 * gc.c (scm_gc_stats): add more obscure stats, such as: mark time,
696 sweep time, total marked cells, total swept cells, and number of
697 times GC was invoked.
698 (gc_start_stats): renamed from scm_gc_start, made static, taught
699 to init the new stats.
700 (gc_end_stats): renamed from scm_gc_end, made static, taught to
701 calculate the new stats.
702 (scm_igc): don't call gc_start_stats unless we are sure that we
703 are indeed going to collect. also, added some timekeeping between
704 the mark and sweep phases.
705 (scm_gc_sweep): count number of cells we sweep as we go.
707 * gc.h: removed prototypes for scm_gc_{start,end}.
709 2000-08-13 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
711 * alist.c (scm_assq, scm_assv, scm_assoc): Report argument type
712 error for the alist rather than the sublist where the type
713 mismatch is discovered.
715 2000-08-13 Neil Jerram <neil@ossau.uklinux.net>
717 * root.c (s_scm_call_with_dynamic_root): Docstring fix - rogue
720 2000-08-12 Neil Jerram <neil@ossau.uklinux.net>
722 * numbers.c (scm_ash): Docstring fix - missing newlines.
724 * ports.c (scm_port_filename): Docstring fix - missing newline.
726 * strports.c (scm_eval_string): Docstring fix - missing newline.
728 * vports.c (s_scm_make_soft_port): Docstring updated so that
731 * strop.c: Docstring fixes - quotation marks and backslashes
734 * numbers.c (s_scm_logand): Docstring fix - "@end lisp" inserted.
736 2000-08-11 Neil Jerram <neil@ossau.uklinux.net>
738 * macros.c: Remove surplus newlines from end of docstrings.
740 * list.c (scm_list_tail): Add @deffnx line to docstring for
743 * keywords.c: Docstring improvements in conjunction with new
744 reference manual doc on keywords.
746 * error.c (scm_error_scm): Fix texinfo syntax error in
747 docstring. (@code(~S) should be @code{~S}.)
749 * dynl.c: Remove surplus newlines from end of docstrings.
751 2000-08-11 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
753 * eval.c (scm_eval): Backward incompatible change: Now takes an
754 environment specifier as second arg. `eval' hereby becomes R5RS
756 (scm_i_eval_x, scm_i_eval): New functions (replace
758 (scm_eval2, scm_eval_3): Deprecated.
759 (scm_top_level_lookup_closure_var): Deprecated.
761 * eval.h: #include "struct.h".
763 * evalext.c (scm_definedp): Have to work before module system is
766 * modules.h (SCM_MODULEP, SCM_VALIDATE_MODULE,
767 SCM_MODULE_OBARRAY, SCM_MODULE_USES, SCM_MODULE_BINDER,
768 SCM_MODULE_EVAL_CLOSURE): New macros.
769 (scm_module_index_obarray, scm_module_index_uses,
770 scm_module_index_binder, scm_module_index_eval_closure): New
771 constants; #include "validate.h".

776 (scm_interaction_environment): New primitive.
778 * symbols.c (scm_can_use_top_level_lookup_closure_var): Removed.
779 #include "modules.h".
781 * strports.c (scm_eval_string): Evaluate in
782 scm_interaction_environment ().
784 * script.c (scm_shell): Pass scm_the_root_module () as second arg
787 * load.c (load): Use `scm_selected_module' to compute second arg
788 to new scm_i_eval_x; Don't call it if module system hasn't booted.
789 (scm_read_and_eval_x): Deprecated.
790 #include "modules.h".
792 * debug.c (scm_local_eval): Use scm_i_eval and scm_i_eval_x.
793 (scm_start_stack): Use scm_i_eval.
795 * strports.c: #include "modules.h".
797 * print.c (scm_simple_format): Be case-insensitive for ~A and ~S
800 2000-08-09 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
802 The following changes are intended to ensure that struct instances
803 are freed before their vtables. It's optimized for the most
804 common case, which is freeing of struct instances.
806 * gc.c (scm_gc_mark, scm_gc_sweep): Remove vcell = 1 magic.
807 (scm_structs_to_free): New variable.
808 (scm_gc_sweep): Hook up structs to free on the scm_structs_to_free
811 * struct.h (SCM_STRUCT_GC_CHAIN, SCM_SET_STRUCT_GC_CHAIN): New
813 (scm_structs_to_free, scm_struct_prehistory): Declare.
815 * struct.c (scm_make_struct, scm_make_vtable_vtable): Structs
816 handles are now double cells; Initialize SCM_STRUCT_GC_CHAIN to
818 (scm_struct_gc_init, scm_free_structs): New GC C hooks.
819 (scm_struct_prehistory): Install them.
821 * init.c (scm_boot_guile_1): Call scm_struct_prehistory.
823 2000-08-06 Marius Vollmer <mvo@zagadka.ping.de>
825 * read.c (scm_flush_ws): Include filename in error message when it
828 2000-08-05 Marius Vollmer <mvo@zagadka.ping.de>
830 * iselect.c: Include <unistd.h>. Thanks to Bertrand Petit!
832 2000-08-02 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
834 * struct.c (scm_make_struct_layout, scm_make_struct,
835 scm_make_vtable_vtable): Updated documentation.
837 * print.c (scm_simple_format): Bugfix: Coerce port before using
840 2000-07-31 Gary Houston <ghouston@arglist.com>
842 * net_db.c: declare h_errno only if HAVE_H_ERRNO is not defined
843 (thanks to Richard Kim for the bug report).
845 2000-07-30 Marius Vollmer <mvo@zagadka.ping.de>
847 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
848 scm_assoc_remove_x): Use scm_delq1_x instead of scm_delq_x, since
849 using the latter is pointless.
851 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
853 * gc.c (scm_gc_sweep): Renamed local variable from 'free' to
854 'free_struct_data' to avoid confusion with stdlib's 'free'.
856 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
858 * vectors.c (scm_make_vector): Fix the initialization order of
859 the vector such that the type cell is initialized last.
861 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
863 * struct.[ch] (scm_struct_init): Made static. Fixed not to rely
864 on the struct cell to be fully initialized.
866 * struct.c (scm_make_struct, scm_make_vtable_vtable): Fix the
867 initialization order of the struct such that the type cell is
870 2000-07-25 Marius Vollmer <mvo@zagadka.ping.de>
872 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
873 scm_assoc_remove_x): Remove only the first cell with a matching
876 2000-07-24 Marius Vollmer <mvo@zagadka.ping.de>
878 * stime.c (scm_strftime): Recognize a return value of zero from
879 strftime as buffer overflow and take care to detect a valid zero
880 length result regardless. Thanks to David Barts!
882 2000-07-23 Marius Vollmer <mvo@zagadka.ping.de>
884 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
885 scm_assoc_remove_x): Remove all cells whose key is eq, eqv, or
886 equal (respectively) to the argument key, not all cells that are
887 eq, eqv, or equal to the first cell with the argument key. Thanks
890 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
892 * gc.h (SCM_FREE_CELL_CDR, SCM_SET_FREE_CELL_CDR), hooks.c
893 (make_hook), modules.c (OBARRAY, USES, BINDER): Pack and unpack
894 SCM values appropriately.
896 * modules.c (scm_standard_eval_closure): Don't pass an inum to
897 scm_makcclo, but rather a long value.
899 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
901 read.c (scm_lreadrecparen), srcprop.c (scm_set_source_property_x):
902 SCM_SETCDR and SCM_WHASHSET macros don't deliver a return value.
903 Thanks to Han-Wen Nienhuys for the bug report.
905 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
907 * root.[ch] (scm_call_catching_errors): Deprecated.
909 * root.c (scm_init_root): Initialize the root smob type using the
910 standard initialization functions.
912 2000-07-17 Marius Vollmer <mvo@zagadka.ping.de>
914 * eval.c (unmemocopy): Don't rely on V being a list of at least
915 one element. Thanks to Bill Schottstaedt!
917 2000-07-15 Michael Livshin <mlivshin@bigfoot.com>
919 * gc.c (scm_done_free): new.
920 expanded comments about scm_done_malloc.
922 * gc.h: added prototype for scm_done_free
924 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
926 * gc.h (scm_take_stdin): Removed.
928 * gc.h (SCM_VALIDATE_CELL): Delegate cell checks to function
929 scm_assert_cell_valid to allow extensions to the checking
930 functionality without need to recompile everything.
932 * gc.[ch] (scm_assert_cell_valid, scm_set_debug_cell_accesses_x):
933 Added as conditionally compiled functions for the case that
934 SCM_DEBUG_CELL_ACCESSES is enabled.
936 * gc.c (debug_cells_p): Added to indicate whether compile-time
937 included cell access debugging is run-time enabled.
939 * gc.[ch] (scm_gc_running_p): Added to indicate that scm_igc is
940 being executed. Intended to be used instead of scm_gc_heap_lock
943 * error.c (scm_error), gdbint.c (SCM_GC_P): Use scm_gc_running_p
944 instead of scm_gc_heap_lock.
946 * gc.c (scm_igc): Set scm_gc_running_p to true while running.
948 * gc.c (scm_mark_locations): Don't mark free cells.
950 * weaks.c (scm_scan_weak_vectors): Use SCM_FREE_CELL_P instead of
953 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
955 * gc.c (scm_mark_locations): Minimized some variable scopes and
956 simplified the code a bit.
958 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
960 * gc.h (SCM_SET_FREE_CELL_TYPE, SCM_SET_FREE_CELL_CDR,
961 SCM_FREE_CELL_P, SCM_FREE_CELL_CDR): Added since free cells
962 should not be accessed via SCM_C[AD]R. Further, using dedicated
963 macros to access free cells allows all other cell accessing macros
964 to treat acesses to free cells as errors, thus enabling better
965 error checks for cell accesses. SCM_FREE_CELL_P is supposed to
966 replace SCM_FREEP some time.
968 * gc.h (SCM_NEWCELL, SCM_NEWCELL2), gc.c (map_free_list,
969 free_list_length, scm_check_freelist, scm_debug_newcell,
970 scm_debug_newcell2, freelist_length, scm_gc_for_newcell,
971 scm_gc_mark, scm_gc_sweep, init_heap_seg): Only use the dedicated
972 cell accessors when accessing free cells.
974 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
976 * gc.h (SCM_CELL_WORD, SCM_CELL_OBJECT): Treat the referenced
977 object as const in order to make the compiler warn about code like
978 SCM_CELL_WORD (x, n) = y. Instead, SCM_SET_CELL_WORD (x, n, y)
981 (SCM_CELL_WORD_LOC, SCM_CARLOC, SCM_CDRLOC): Return the address
982 as an address to a non-const object, since these macros are used
983 to allow direct write access to objects.
985 2000-07-07 Dirk Herrmann <D.Herrmann@tu-bs.de>
987 * hashtab.c (scm_hash_fn_create_handle_x): Signal an error if the
988 given hash table has no slots.
990 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
992 * gc.c (policy_on_error): Added in order to allow alloc_some_heap
993 to react to malloc failures in a context dependent way.
995 (scm_check_freelist): No need to flush streams before abort().
997 (scm_gc_for_newcell): Try to allocate new memory in three phases:
998 grow heap if preferred, if still no memory available collect
999 garbage, if still no memory available grow heap.
1001 (heap_segment_table_size): Added to always reflect the actual
1002 size of the heap segment table, because scm_n_heap_segs may differ
1003 from the heap segment table size.
1005 (alloc_some_heap): In case of malloc failure, react according to
1006 the new policy_on_error parameter (either return to caller or
1007 abort immediately). Further, keep heap_segment_table_size up to
1010 (scm_init_storage): Initialize heap_segment_table_size.
1012 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
1014 * gh.h: Don't include <stdio.h>. Thanks to Han-Wen Nienhuys for
1017 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1019 * __scm.h (SCM_OUTOFRANGE, SCM_NALLOC, SCM_HUP_SIGNAL,
1020 SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL,
1021 SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL, SCM_SIG_ORD,
1022 SCM_ORD_SIG, SCM_NUM_SIGS): Re-introduce these as deprecated
1025 * error.c (scm_wta): Re-introduce dispatching for SCM_OUTOFRANGE
1026 and SCM_NALLOC, but as a deprecated feature.
1028 2000-06-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1030 * debug.c: Added #include fluids.h.
1032 * numbers.c (scm_gr_p, scm_leq_p, scm_geq_p): Turned into
1033 primitive generics. (Thanks to Nicolas Neuss.)
1035 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1037 * gc.c (alloc_some_heap): Use scm_memory_error to indicate a
1038 failed attempt to get additional memory from the system.
1040 (scm_gc_for_newcell): Changed the control structure to make the
1041 behaviour explicit for the case that gc is not able to free any
1044 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1046 * __scm.h (SCM_OUTOFRANGE): Removed.
1048 * error.c (scm_wta): Removed sick dispatch code for range
1049 errors. (More sick dispatches still to be removed.)
1051 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
1052 scm_hash_fn_remove_x): Eliminate redundant test for if unsigned
1053 value is non-negative. Use scm_out_of_range to signal range
1056 * hooks.c (make_hook), unif.c (scm_aind): Use scm_out_of_range to
1057 signal range errors.
1059 * list.c (scm_list_ref, scm_list_set_x, scm_list_cdr_set_x): Fix
1060 error reporting (now uses original input parameter to report wrong
1061 type argument errors). Use SCM_OUT_OF_RANGE to report range
1062 errors and SCM_WRONG_TYPE_ARG to report type errors.
1064 * strings.c (scm_substring): Make range checks for negative
1065 values explicit (former behaviour relied on an implicit
1066 conversion from signed to unsigned). Don't use SCM_ASSERT for
1069 * unif.c (scm_aind, scm_transpose_array, scm_bit_set_star_x,
1070 scm_bit_count_star): Use scm_out_of_range to signal range
1073 * unif.c (scm_transpose_array, scm_bit_position), vectors.c
1074 (scm_vector_ref, scm_vector_set_x, scm_vector_move_left_x,
1075 scm_vector_move_right_x): Use SCM_ASSERT_RANGE to check ranges.
1077 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1079 * validate.h (SCM_VALIDATE_INUM_MIN_COPY,
1080 SCM_VALIDATE_INUM_MIN_DEF_COPY, SCM_VALIDATE_INUM_RANGE_COPY):
1081 Perform all range checks based on the input value. The former way
1082 of using the value that is assigned to the target variable fails
1083 if the assignment to the target variable itself can change the
1084 value because of type conversion.
1086 (SCM_ASSERT_RANGE): Use scm_out_of_range to signal range errors.
1088 2000-06-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1090 * gc.c (scm_gc_for_newcell): Behave gracefully also if scm_igc
1091 doesn't yield any new cells. In theory this could happen if all
1092 cells allocated with NEWCELL are either in use or conservatively
1093 marked and all cluster spine cells are conservatively marked.
1096 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1098 * __scm.h (SCM_NALLOC): Removed.
1100 * error.c (scm_wta): Removed sick dispatch code for memory
1101 errors. (More sick dispatches still to be removed.)
1103 * numbers.c (scm_mkbig, scm_adjbig), ports.c (scm_make_port_type),
1104 random.c (scm_i_copy_rstate, scm_c_make_rstate), smob.c
1105 (scm_make_smob_type), srcprop.c (scm_make_srcprops), vectors.c
1106 (scm_vector_set_length_x): Now using scm_memory_error to signal
1109 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1111 * __scm.h: Removed some commented code and fixed some comments.
1113 (SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL,
1114 SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL,
1115 SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS): Removed.
1117 * async.c: Removed some commented code.
1119 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1121 * gc.c (scm_gc_mark, scm_gc_sweep, scm_must_malloc,
1122 scm_must_realloc, scm_must_free, alloc_some_heap): Use the
1123 appropriate error signalling function.
1125 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1127 * root.h (scm_first_type): Removed.
1129 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1131 * gc.c (MIN_GC_YIELD): Removed.
1133 2000-06-28 Michael Livshin <mlivshin@bigfoot.com>
1135 * gc.c (scm_gc_for_newcell): don't try to do GC if it's blocked,
1138 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1140 * async.c (scm_gc_async, scm_gc_vcell, scm_sys_gc_async_thunk):
1143 (scm_init_async): Moved initialization for scm_gc_async and
1144 scm_gc_vcell to gc.c. Moved initialization of scm_asyncs here
1147 * async.h (scm_gc_async): Not globally visible any more.
1149 * gc.c (scm_gc_stats): Made callable even from within regions
1150 where gc is blocked.
1152 (scm_gc_end): Eliminate the hardcoding of the marking of the
1153 scm_gc_async from the gc core.
1155 (scm_init_storage): Don't initialize the scm_asyncs list here.
1156 This is now done in asyncs.c.
1158 (scm_gc_vcell): Moved here from async.c.
1160 (gc_async): Renamed from scm_gc_async, moved here from async.c
1163 (gc_async_thunk): Renamed from scm_sys_gc_async_thunk and moved
1166 (mark_gc_async): New hook function for scm_after_gc_c_hook.
1168 (scm_init_gc): Added initialization of scm_gc_vcell and
1169 gc_async. Further, add mark_gc_async to scm_after_gc_c_hook.
1171 * init.c (scm_boot_guile_1): scm_init_gc requires asyncs to be
1174 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1176 * gc.c (scm_igc): Removed commented code that once was intended
1177 to unprotect struct types with no instances.
1179 * root.h (scm_type_obj_list): Removed.
1181 2000-06-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
1183 * async.c (scm_init_async): Switch to standard way of smob
1186 2000-06-21 Michael Livshin <mlivshin@bigfoot.com>
1188 * guile-doc-snarf.in: use cut instead of sed, that's much much
1189 faster. also, don't call basename more than needed. and, to gain
1190 a couple of microseconds more, don't call cat needlessly. (thanks
1193 2000-06-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
1195 * guile-snarf.awk.in, guile-snarf.in, snarf.h: Rename SCM__I to
1196 SCM_SNARF_INIT_START, SCM__D to SCM_SNARF_DOC_START, SCM__S to
1197 SCM_SNARF_DOCSTRING_START and SCM__E to SCM_SNARF_DOCSTRING_END.
1199 2000-06-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1201 * eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
1202 #include "libguile/fluids.h".
1204 * eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
1205 SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
1207 * root.h (scm_top_level_lookup_closure_var,
1208 scm_system_transformer): Removed. (It's no sense in having the
1209 *variable* be a "fluid".)
1211 * root.c (mark_root): Removed marking of
1212 s->top_level_lookup_closure_var and s->system_transformer.
1214 * modules.c (scm_selected_module): the_module is now a fluid.
1216 2000-06-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1218 * gc.h, tags.h: Be kind to compilers which must see hash signs in
1219 column 0. (Thanks to Ian Grant.)
1221 * numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
1222 the long_long type. (Thanks to Bernard Urban.)
1224 2000-06-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1226 * gc.c, gc.h (scm_default_init_heap_size_1,
1227 scm_default_min_yield_1, scm_default_init_heap_size_2,
1228 scm_default_min_yield_2, scm_default_max_segment_size): New global
1229 variables. Can be customized by the application before booting
1230 Guile. (We might want to be able to control these parameters
1231 dynamically through the "options interface" in the future, but
1232 note that that is additional functionality. Here we're giving
1233 default values which the environment variables can override.)
1235 * list.c (scm_cons_star): Updated comment.
1237 * smob.h: Changed comments for scm_make_smob_type and
1238 scm_make_smob_type_mfpe, warning that the latter might be
1239 deprecated in a future release.
1241 2000-06-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1243 * list.[ch] (scm_cons_star/cons*): Renamed from
1244 scm_list_star/list*.
1246 * list.[ch] (scm_list_star/list*): Provided as a deprecated alias
1247 for scm_cons_star/cons*.
1249 * gc.c (scm_protect_object): Updated comment.
1251 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX): Removed.
1253 * tags.h (SCM_UNPACK_CAR, SCM_NDOUBLE_CELLP): Removed.
1255 2000-06-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1257 * init.c, init.h (scm_initialized_p): Renamed from `initialized'
1260 * gdbint.c (gdb_print): Print warning instead of calling scm_write
1261 if Guile isn't yet initialized.
1263 * print.c (scm_current_pstate, scm_make_print_state): Simplified
1264 tests, using the assumption that Guile has been initialized.
1266 Sun Jun 18 14:45:21 2000 Greg J. Badros <gjb@cs.washington.edu>
1268 * print.c (s_scm_current_pstate): Do not segfault when the
1269 print_state_pool is unitialized in `current-pstate', and better
1270 verify its state before altering it in scm_make_print_state().
1272 2000-06-18 Michael Livshin <mlivshin@bigfoot.com>
1274 * scmsigs.c (s_scm_sigaction): guard the SIGIOT case with an
1275 #ifdef -- it's missing on at least one platform. (thanks to
1278 2000-06-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1280 * list.c (list*): Added documentation from common-list.scm.
1282 2000-06-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
1284 * gc.c (scm_unprotect_object): The reference count is guaranteed
1285 to be a positive number.
1287 2000-06-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1289 * eval.c: Updated comment above scm_map.
1291 2000-06-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1293 * gc.c (scm_protect_object): Avoid looking up the object handle
1295 (scm_unprotect_object): Abort if scm_unprotect_object is called on
1296 an unprotected object.
1298 2000-06-14 Michael Livshin <mlivshin@bigfoot.com>
1300 * gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
1303 2000-06-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1305 * socket.c (scm_getsockopt): Changed type for `optlen' from int to
1307 (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
1308 Ditto for `tmp_size'.
1309 (scm_addr_buffer_size): Changed type from int to size_t.
1311 * random.c: #include <string.h>. (Needed by memcpy.)
1313 * guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
1314 indicating stdin, instead of "" and don't reset ARGC. This is a
1315 workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
1316 it is correct, and perhaps even better.
1318 2000-06-14 Gary Houston <ghouston@arglist.com>
1320 * scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not
1321 defined, add SA_RESTART to the sigaction flags correctly
1322 (thanks to Dale P. Smith).
1324 2000-06-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1326 * strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
1328 * net_db.c (scm_resolv_error): Only use macro NETDB_INTERNAL if
1329 defined. It isn't on sgi irix 5.3. (Thanks to Bill Schottstaedt.)
1331 * Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
1333 2000-06-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1335 * fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
1336 since read and write buffers are allocated by `malloc'.
1338 * Makefile.am: Removed old test code.
1340 * gh_test_c.c, gh_test_repl.c: Removed.
1342 2000-06-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1344 * iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2
1347 * inet_aton.c (inet_aton): Cast init value for `cp'.
1349 * ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
1352 * symbols.c (scm_intern_obarray_soft,
1353 scm_sysintern0_no_module_lookup): Cast `name' to unsigned char ptr
1354 in calls to scm_strhash.
1356 * strports.c (st_resize_port): Substituted SCM_UCHARS for
1358 (st_write): Cast argument to strncpy to char ptr.
1359 (scm_mkstrport): Substituted SCM_ROUCHARS for SCM_ROCHARS.
1360 (scm_strport_to_string): Cast argument to scm_makfromstr to char
1363 * ports.c (scm_ungetc): Cast value to unsigned char ptr before
1364 storing in putback_buf.
1365 (scm_unread_string): Substituted SCM_ROCHARS for SCM_ROUCHARS.
1367 * ioext.c (s_scm_read_line): Cast result of call to
1368 scm_do_read_line to unsigned char ptr.
1370 * gdbint.c (SEND_STRING): Cast argument to char pointer.
1372 * fports.c (fport_flush): Declare `ptr' as unsigned char (was
1375 * Makefile.am (DOT_DOC_FILES): List doc-files explicitly. (We
1376 shouldn't use Make rules which aren't supported by most Make
1378 (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h". (We don't
1379 want these dependencies recorded, since they would get bogus
1380 relative paths; libguile.h is only used in gh.h and guile.c.)
1381 (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
1382 (guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
1383 (modinclude_HEADERS): Removed kw.h.
1385 * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
1386 (The preprocessor might insert spaces before the identifier.)
1388 * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
1389 Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
1391 * smob.h (scm_smobfuns): Removed deprecated type.
1393 * smob.c, smob.h (scm_newsmob): Removed deprecated function.
1394 (Replaced by `scm_make_smob_type'.)
1396 * keywords.c (scm_tc16_kw): Removed deprecated type.
1397 (Replaced by scm_tc16_keyword.)
1399 * kw.h: Removed deprecated header file.
1401 * evalext.c (serial-map): Removed deprected alias for scm_map.
1402 (Has been replaced by `map-in-order'.)
1404 * ramap.c (serial-array-copy!, serial-array-map!): Removed
1405 depracted aliases. (Replaced by `array-copy-in-order!' and
1406 `array-map-in-order'.)
1408 2000-06-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1410 * gc.h (SCM_VALIDATE_CELL): Rewritten.
1411 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
1412 SCM_SET_CELL_OBJECT): Use new version of SCM_VALIDATE_CELL.
1413 (Thanks to Han-Wen Nienhuys.)
1415 2000-06-10 Michael Livshin <mlivshin@bigfoot.com>
1417 * guile-doc-snarf.in: don't pipe the CPP output right into sed --
1418 write it to the temp file first and check the CPP return code.
1419 (I introduced this bug earlier, and this probably caused people
1420 with non-GNU C preprocessors to get empty *.x files and not to
1421 have the build fail right away...).
1423 * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
1424 -- at least my libc5-based Linux system doesn't define SIGSYS.
1426 2000-06-08 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1428 * snarf.h, guile-snarf.awk.in, guile-snarf.in: Replaced snarf
1429 markers with identifiers (SCM__I, SCM__D, SCM__S, SCM__E).
1430 (Thanks to Bernard Urban.)
1432 2000-06-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1434 * modules.c (scm_system_module_env_p): Fixed detection of system
1437 2000-06-06 Marius Vollmer <mvo@zagadka.ping.de>
1439 * scmsigs.c (scm_sigaction): Silently ignore setting handlers for
1440 `program error signals' because they can't currently be handled by
1443 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1445 * procs.h (SCM_SET_SUBRF): Added.
1447 * procs.c (scm_make_subr_opt): Don't assign to SCM_SUBRF, use
1448 SCM_SET_SUBRF instead. Thanks to Bernard Urban for the bug
1451 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1453 * gc.h (SCM_CARLOC, SCM_CDRLOC): Don't take the address of a SCM
1456 * sort.c (scm_sorted_p, scm_merge, scm_merge_list_x,
1457 scm_merge_list_step): Don't take the address of SCM_CAR. Use
1458 SCM_CARLOC instead. Thanks to Bernard Urban for the bug report.
1460 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1462 * boolean.h (SCM_TRUE_P): Removed, as people might use it as a
1463 replacement for !SCM_FALSEP.
1465 * backtrace.c (display_error_body), boolean.h (SCM_BOOLP), gc.c
1466 (scm_unhash_name), gh_data.c (gh_module_lookup), load.c
1467 (scm_primitive_load), print.c (scm_simple_format), procs.c
1468 (scm_procedure_documentation), procs.h (SCM_TOP_LEVEL), ramap.c
1469 (scm_array_fill_int), scmsigs.c (scm_sigaction), stacks.c
1470 (narrow_stack, scm_make_stack, scm_stack_id), symbols.c
1471 (scm_string_to_obarray_symbol), throw.c (scm_catch,
1472 scm_lazy_catch, scm_ithrow), unif.c (scm_make_uve, scm_array_p,
1473 scm_array_set_x, scm_bit_set_star_x, scm_bit_count_star),
1474 validate.h (SCM_VALIDATE_BOOL_COPY, SCM_VALIDATE_PROC): Replace
1475 uses of SCM_TRUE_P (x) with SCM_EQ_P (x, SCM_BOOL_T).
1477 2000-06-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1479 * eval.c (scm_badformalsp): New static function.
1480 (SCM_CEVAL): Check arguments for procedure-with-setter closures.
1481 (Thanks to Keisuke Nishida.)
1483 The major reason for Guile's slow loading speed has been the fact
1484 that a chain of Scheme level procedures has been evaluated for
1485 every top-level symbol lookup during the first pass through the
1488 The following is a kludge which I suggested four years ago, and
1489 which I've repeatedly suggested since. Personally, I've never
1490 been bothered by Guile's slow loading speed, so I thought I would
1491 let someone else do it...
1493 But since the new environments will be included first in
1494 Guile-1.5, I thought it would make people happy to get the kludge
1497 * modules.c: Added #include "libguile/vectors.h";
1498 Added #include "libguile/hashtab.h";
1499 Added #include "libguile/struct.h";
1500 Added #include "libguile/variable.h";
1501 Capture Scheme level `module-make-local-var!' to be used in the
1502 standard eval closure.
1503 (scm_standard_eval_closure): New primitive.
1505 * modules.h (scm_standard_eval_closure): Declare.
1507 * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
1508 instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
1510 * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
1511 standard eval closures.
1513 * variable.c: Code layout fixes.
1515 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1517 * Makefile.am: Added LIBS line to libpath which accidentally
1518 disappeared in the change of 2000-06-01.
1519 (Thanks to Dale P. Smith.)
1521 2000-06-03 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1523 * scmsigs.c (scm_segfault): Removed. (Was probably added by
1524 mistake since it is not mentioned in ChangeLog.)
1526 * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
1527 avoid compiler warnings in gcc. (Does this work for other
1530 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1532 * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
1534 (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
1535 SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1. It's not correct to take
1536 the address of these expressions since they use SCM_VALIDATE_CELL.
1537 (Thanks to Bernard Urban.)
1539 * dynl.c: Changed #include <ltdl.h> --> #include
1540 "libltdl/ltdl.h". (Thanks to Bill Schottstaedt.)
1542 2000-06-01 Craig Brozefsky <craig@red-bean.com>
1544 * Makefile.am: libguile_la_LDFLAGS gets -version-info args
1545 from GUILE-VERSION definition of LIBGUILE version. Added to
1546 libpath.h definitions for guileversion and libguileversion which
1547 both get their values from GUILE-VERSION definition.
1549 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1551 * numbers.h (SCM_BIGP): Don't use SCM_SMOB_PREDICATE in header
1552 file: Code using numbers should not be required to include
1555 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1557 * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
1558 mit-pthreads.c, mit-pthreads.h: Deleted.
1560 * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]: Drop
1561 references to deleted files and fsu/mit thread support in
1564 2000-05-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1566 * hooks.c (symbol_name, scm_create_hook): Restored the original
1567 behaviour of scm_create_hook. Changing it was bad as Carl
1568 R. Witty has pointed out.
1570 * gc.c (scm_init_gc): We can still rely on scm_create_hook to
1573 2000-05-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
1575 * gc.c (scm_init_gc): Protect scm_after_gc_hook, since this will
1576 soon not be done by scm_create_hook any longer.
1578 * hooks.c (make_hook, print_hook, scm_create_hook,
1579 scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
1580 SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
1581 scm_make_hook_with_name), init.c (scm_boot_guile_1): Hooks no
1582 longer have names. As an intermediate solution, the name
1583 predicate is emulated via object properties, but use of this
1584 feature is deprecated.
1586 * hooks.h (scm_free_hook): Removed, as it is never defined.
1588 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1590 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
1591 Un-deprecated since otherwise user code can't determine whether a
1592 number fits into an inum any longer. The names should be changed
1595 * numbers.c (scm_big2inum): Eliminated use of SCM_UNEGFIXABLE.
1597 * tags.h (SCM_UNPACK_CAR): Deprecated.
1599 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1601 * filesys.h (SCM_OPDIRP), fluids.h (SCM_FLUIDP, SCM_FLUID_NUM),
1602 fports.h (SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP), hooks.h
1603 (SCM_HOOK_ARITY), keywords.h (SCM_KEYWORDP, SCM_KEYWORDSYM),
1604 numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
1605 Replace SCM_UNPACK_CAR appropriately. Don't access cells via
1606 SCM_{SET}?C[AD]R unless they are known to be cons cells.
1608 * gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
1609 init_heap_seg): Remove unused struct member variable 'valid'.
1611 2000-05-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
1613 * fports.c (fport_write), ports.c (scm_markstream, scm_port_mode,
1614 scm_print_port_mode), ports.h (SCM_OPPORTP, SCM_OPINPORTP,
1615 SCM_OPOUTPORTP, SCM_INPUT_PORT_P, SCM_OUTPUT_PORT_P, SCM_OPENP),
1616 procs.h (SCM_CLOSCAR), unif.h (SCM_ARRAY_NDIM, SCM_ARRAY_CONTP),
1617 variable.h (SCM_VARIABLEP): Replace SCM_UNPACK_CAR
1620 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1622 * gc.c (free_list_length), hash.c (scm_hasher), macros.c
1623 (scm_macro_type), objects.c (scm_class_of), options.c
1624 (scm_options), print.c (scm_iprin1), strports.c (st_seek), throw.c
1625 (SCM_LAZY_CATCH_P): Replace SCM_UNPACK_CAR appropriately.
1627 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1629 * eval.c (scm_macroexp, SCM_CEVAL, scm_force), tags.h: Replace
1630 SCM_UNPACK_CAR with SCM_CELL_TYPE or SCM_CELL_WORD_0.
1632 * eval.c (scm_force): Add documentation.
1634 * eval.c (scm_force, scm_cons_source): Don't access cells via
1635 SCM_{SET}?C[AD]R unless they are known to be cons cells.
1637 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1639 * strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
1640 (SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP): Deprecated.
1642 * gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT): Removed #ifdef
1643 nosve #endif conditionally compiled code.
1645 2000-05-23 Michael Livshin <mlivshin@bigfoot.com>
1647 * gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
1649 2000-05-22 Michael Livshin <mlivshin@bigfoot.com>
1651 * guile-doc-snarf.in: put the preprocessed file through sed to
1652 trim all lines to 1024 chars. I hope it doesn't break anybody's
1653 sed. we'll see. (note: this is lossy trimming, i.e. the spill
1654 isn't wrapped around but actually chopped off. this seemed to me
1655 safe because the current snarfer doesn't understand multi-line
1656 cookies anyway. in the long term, it would be nice not to depend
1657 on AWK for anything.)
1659 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
1660 the previous change to this macros, after deciding to torture the
1663 2000-05-21 Michael Livshin <mlivshin@bigfoot.com>
1665 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
1666 the yucky, ugly and nasty conditional compilation back. sorry,
1667 but it was either that or requiring GAWK to build Guile.
1668 (lots of places): removed the code that implemented the old GC
1671 * init.c (scm_boot_guile_1): removed the code conditioned on
1672 !GUILE_NEW_GC_SCHEME.
1674 * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
1676 * gc.c (scm_protect_object, scm_unprotect_object): change the
1677 implementation to more efficient (at least in the time complexity
1678 sense). the calls should now also be thread-safe -- I suspect
1679 that people expect them to be. (thanks to Han-Wen Nienhuys)
1680 (lots of places): removed the code that implemented the old GC
1683 * hashtab.c (scm_hash_fn_create_handle_x): add missing
1684 SCM_REALLOW_INTS before return. I really wonder about the
1685 possible interactions between hashtables, threads & GC. it
1686 doesn't look healthy at all.
1688 2000-05-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1690 * unif.c (scm_bit_count): Fixed the parameter checks. Thanks to
1693 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1695 * __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_): Added as a new
1696 debug option to verify all accesses to cells actually access
1697 objects on the heap.
1699 * gc.h (SCM_VALIDATE_CELL): Added. Only performs validation if
1700 SCM_DEBUG_CELL_ACCESSES is set to 1.
1702 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
1703 SCM_SET_CELL_OBJECT): Use SCM_VALIDATE_CELL to check every cell
1706 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1708 * gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs,
1709 gh_scm2floats, gh_scm2doubles): Change !SCM_NIMP to SCM_IMP.
1711 * gc.c (scm_cellp): Fixed and simplified.
1713 * throw.c (JBJMPBUF, SETJBJMPBUF, SCM_JBDFRAME, SCM_SETJBDFRAME,
1714 make_jmpbuf, scm_init_throw): Now using double cells to represent
1715 jump buffers when using debug extensions.
1719 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1721 * gh.h gh_data.c gh_funcs.c (gh_new_procedure*, gh_chars2byvect,

1723 gh_doubles2dvect, gh_doubles2scm, gh_define, gh_lookup,
1724 gh_module_lookup): Accept const pointers as parameters.
1726 * gh.h gh_data.c (gh_int2scmb): Deprecated.
1728 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1730 * __scm.h (SCM_DEBUG_REST_ARGUMENT): Renamed from
1731 SCM_DEBUG_REST_ARGUMENTS in order to clarify that we don't test
1732 the actual arguments in the list, but rather the rest argument as
1733 a list of arguments.
1735 * validate.h (SCM_VALIDATE_REST_ARGUMENT): Added.
1737 * async.c (scm_noop), eval.c (scm_map, scm_for_each), list.c
1738 (scm_list_star, scm_append, scm_append_x), ports.c
1739 (scm_close_all_ports_except), ramap.c (scm_array_map_x,
1740 scm_array_for_each), regex-posix.c (scm_make_regexp), stacks.c
1741 (scm_make_stack), strings.c (scm_string_append), struct.c
1742 (scm_make_struct, scm_make_vtable_vtable): Validate rest arguments.
1744 * dynl.c (DYNL_GLOBAL, sysdep_dynl_link, kw_global, sym_global,
1745 scm_dynamic_link, scm_init_dynamic_linking), dynl.h
1746 (scm_dynamic_link): Removed possibility to pass flags to
1747 scm_dynamic_link, as it had no effect anyway.
1749 * filesys.c (scm_fcntl): Made single optional rest argument into
1750 a standard optional argument.
1752 * hooks.c (scm_run_hook): A list of rest arguments is never
1755 * list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
1756 strings.c (scm_string_append): Don't perform half-hearted checks
1757 to see whether the rest argument forms a proper list any more, use
1758 SCM_VALIDATE_REST_ARGUMENTS instead.
1760 * ports.c (scm_close_all_ports_except): Accept empty list of rest
1763 * posix.c (scm_convert_exec_args), print.c (scm_simple_format):
1764 Simplify verification of rest argument.
1766 * stacks.c (scm_make_stack), stacks.h (scm_make_stack), throw.c
1767 (ss_handler, handler_message): Make first mandatory rest argument
1768 of scm_make_stack into a standard mandatory argument.
1770 * unif.c (scm_transpose_array, scm_enclose_array,
1771 scm_array_in_bounds_p), unif.h (scm_transpose_array,
1772 scm_enclose_array, scm_array_in_bounds_p): Make first mandatory
1773 rest argument into a standard mandatory argument.
1775 2000-05-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
1777 * __scm.h: Added SCM_DEBUG as default debug option. (Thanks to
1778 Keisuke Nishida for the suggestion.) Added debug option
1779 SCM_DEBUG_REST_ARGUMENTS.
1781 * eval.c (scm_map, scm_for_each): Make sure all lists have the
1782 same length. Also, removed redundant parameter checks.
1784 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1786 * Makefile.am: Let 'make clean' remove *.x and *.doc files.
1788 * __scm.h: Improved explanation of giving options to make.
1790 * __scm.h (SCM_DEBUG_TYPING_STRICTNESS), tags.h
1791 (SCM_STRICT_TYPING, SCM_DEBUG_TYPING_STRICTNESS): Renamed
1792 SCM_STRICT_TYPING to SCM_DEBUG_TYPING_STRICTNESS and moved the
1793 corresponding declaration and comment to __scm.h.
1795 * _scm.h (errno), gc.h (SCM_CELLPTR, SCM_PTR_LT), numbers.c
1796 (scm_remainder, scm_modulo), numbers.h (SCM_SRS, SCM_MAKINUM,
1797 SCM_INUM): Removed conditionally compiled code for Turbo C.
1799 * gdbint.c (gdb_maybe_valid_type_p): Eliminated call to scm_tag.
1800 That check can be assumed to be redundant except for very rare
1801 conditions that actually indicate broken heap data.
1803 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1805 * numbers.c (scm_logcount, scm_integer_length): Reordered
1808 2000-05-15 Gary Houston <ghouston@arglist.com>
1810 * stime.c (scm_strftime): don't reset TZ if zone is an empty
1811 string. append a "0" to the zone for TZ.
1813 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
1815 * numbers.c (scm_logbit_p, scm_bit_extract): Reordered dispatch
1818 (scm_bit_extract): Fixed handling of bignums.
1820 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
1822 * async.c (scm_sys_gc_async_thunk), chars.h (SCM_ICHRP, SCM_ICHR,
1823 SCM_MAKICHR), continuations.h (SCM_SETJMPBUF), error.c
1824 (scm_sysmissing), error.h (scm_sysmissing), evalext.c

1826 keywords.c (scm_tc16_kw, scm_init_keywords), ports.h (SCM_CRDY,
1827 SCM_INPORTP, SCM_OUTPORTP), ramap.c ('serial-array-copy!,
1828 'serial-array-map!), smob.c (scm_newsmob), smob.h (scm_smobfuns,
1829 scm_newsmob), tag.c (scm_tag), tag.h (scm_tag), tags.h
1830 (scm_tc16_flo, scm_tc_flo, scm_tc_dblr, scm_tc_dblc): Wrapped
1831 deprecated code between #if (SCM_DEBUG_DEPRECATED == 0) #endif.
1833 * fports.c (scm_fport_buffer_add), ports.c (scm_input_port_p,
1834 scm_output_port_p), print.c (scm_get_print_state), validate.h
1835 (SCM_VALIDATE_CHAR): Replace use of deprecated macros
1836 SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
1837 SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
1839 2000-05-14 Gary Houston <ghouston@arglist.com>
1841 * stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
1842 TZ environment variable so that the %Z format returns the zone
1843 from the input vector instead of the system default.
1845 from Keisuke Nishida:
1846 * fports.c (scm_setvbuf): minor docstring fix.
1847 * ports.h (scm_generic_fgets): obsolete prototype deleted.
1849 2000-05-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
1851 * __scm.h: Added new section for debugging options.
1853 (SCM_DEBUG_DEPRECATED): If 1, no deprecated code is included to
1854 help developers to get rid of references to deprecated code.
1856 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,
1857 SCM_FIXABLE, SCM_FLOBUFLEN): These macros are no longer provided
1858 as part of the interface and are marked as deprecated in the
1861 * numbers.c (scm_make_real, scm_make_complex): Inlined the
1862 corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
1865 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,
1866 SCM_REAL, SCM_IMAG, SCM_REALPART, scm_makdbl, SCM_SINGP,
1867 SCM_NO_BIGDIG, SCM_NUM2DBL, scm_dblproc): Deprecated.
1869 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1871 * gc.h (scm_cell, SCM_CELL_WORD, SCM_CELL_OBJECT,
1872 SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT): Scheme cells now consist
1873 of two scm_bits_t values instead of two SCM values, because it is
1874 legal for cell entries to hold values that are not scheme objects.
1876 (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
1877 Use SCM_SETC[AD]R to modify contents of pairs.
1879 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1881 * numbers.c (IS_INF, isfinite): Added FIXME comment.
1883 (scm_abs, scm_magnitude): Make these two independent of each
1884 other. scm_abs now reports an error if given a complex argument.
1886 (scm_istr2flo, scm_integer_p). Use SCM_REAL_VALUE instead of
1887 SCM_REALPART if the object is known to be real.
1889 (scm_init_numbers): No need to use SCM_NEWREAL macro for speed
1892 * numbers.h (SCM_SINGP): Set to 0 instead of SCM_BOOL_F.
1894 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1896 * eq.c (scm_eqv_p): Separate handling of real and complex
1897 values. Remove #ifdef SCM_BIGDIG #endif test.
1899 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_scm2floats,
1900 gh_scm2doubles), hash.c (scm_hasher), ramap.c (scm_array_fill_int,
1901 ramap_rp, scm_array_map_x), random.c (vector_scale,
1902 vector_sum_squares), unif.c (scm_make_uve, scm_array_p,
1903 scm_array_set_x): Use SCM_REAL_VALUE instead of SCM_REALPART if
1904 the object is known to be real. Use SCM_COMPLEXP instead of
1905 deprecated SCM_CPLXP. Use SCM_INEXACTP instead of deprecated
1908 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1910 * numbers.c: No need to include unif.h.
1912 (IS_INF): Returned to old test for now: x == x + 1 will not work
1913 for large numbers due to rounding errors.
1914 Thanks to Kalle Olavi Niemitalo.
1916 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1918 * numbers.c (scm_divbigdig): Removed outdated comment.
1920 (scm_number_to_string, scm_string_to_number, scm_number_p,
1921 scm_real_p, scm_integer_p, scm_inexact_p, scm_gr_p, scm_leq_p,
1922 scm_geq_p, scm_make_rectangular, scm_make_polar,
1923 scm_inexact_to_exact): Added comments.
1925 (add1, scm_init_numbers): Removed add1.
1927 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1929 * numbers.c (IS_INF): The new test is x == x + 1. The old test
1930 x == x/2 did not work for zero values. Thanks to Han-Wen Nienhuys
1933 (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
1934 scm_num2long, scm_num2long_long, scm_num2ulong): Reordered
1937 2000-05-09 Marius Vollmer <mvo@zagadka.ping.de>
1939 * scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
1940 SIGILL and SIGBUS signals. These signals are not continuable and
1941 must be handled for real right away.
1943 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1945 * numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,
1946 scm_real_part, scm_imag_part, scm_magnitude,
1947 scm_inexact_to_exact): Reordered dispatch sequence.
1949 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1951 * feature.c: No need to include "libguile/smob.h"
1953 (scm_loc_features, features, scm_add_feature, scm_init_feature):
1954 Removed variable 'scm_loc_features' as a pointer to the SCM value
1955 holding the features list. Using variable 'features' instead,
1956 which holds the interned pair. Thus, SCM_SETCDR can be used
1957 instead of pointer trickery.
1959 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1961 * alist.c (scm_acons): Use SCM{_SET}?_CELL_OBJECT as long as a
1962 cell is not known to be a valid pair.
1964 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1966 * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1): Removed
1967 ASRTSYNTAX. Using SCM_ASSYNT instead.
1969 (scm_m_body): Don't create a redundant cons cell.
1971 (scm_m_do): Removed redundant test 'bodycheck'.
1973 (bodycheck): Removed.
1975 * stacks.c (stack_depth, read_frame, read_frames): Removed
1976 redundant calculation of size, minimized some variable scopes.
1978 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1980 * pairs.c (scm_cons, scm_cons2): Use SCM{_SET}?_CELL_OBJECT as
1981 long as a cell is not known to be a valid pair.
1983 (scm_pair_p): Eliminated redundant SCM_IMP test.
1985 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1987 * eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,
1988 scm_deval_args): Eliminated redundant SCM_IMP tests.
1990 * hashtab.c (scm_ihashx, scm_sloppy_assx, scm_delx_x), weaks.c
1991 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
1992 scm_make_doubly_weak_hash_table): Fixed critical sections.
1993 Thanks to Keisuke Nishida.
1995 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1997 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
1998 Fixed some goto-related initialization bugs (introduced by me).
2000 2000-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
2002 * numbers.h (SCM_INUM0): Uses SCM_MAKINUM instead of SCM_PACK.
2004 * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj): Removed.
2006 (DYNL_FILENAME, DYNL_HANDLE): Use SCM_CELL... macros instead of
2009 (SET_DYNL_HANDLE): Added.
2011 (scm_dynamic_object_p): Simplified.
2013 (scm_dynamic_unlink, scm_dynamic_func): Changed comment. Deliver
2014 better error message when accessing unlinked dynamic objects.
2015 Eliminated call to get_dynl_obj.
2017 2000-05-03 Marius Vollmer <mvo@zagadka.ping.de>
2019 * scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
2020 be an array of function pointers instead of being a pointer to an
2021 array returning function. Thanks to Kalle Olavi Niemitalo!
2023 2000-05-03 Dirk Herrmann <D.Herrmann@tu-bs.de>
2025 * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
2026 (scm_divbigbig, scm_divbigint): Don't return zero any more to
2027 indicate that a division has a remainder, return SCM_UNDEFINED
2028 instead. It is improbable that anyone actually used these
2029 functions outside of numbers.c. For this reason and due to the
2030 change in behaviour the functions are static now. Thus, if
2031 surprisingly there are users of these functions they will at least
2034 * numbers.c: Removed #ifdef SCM_BIGDIG #endif in those functions,
2035 that already have a clean dispatch order. Note: SCM_BIGDIG is
2038 * numbers.c (scm_inexact_p): Simplified.
2040 * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
2041 scm_product, scm_num2dbl, scm_angle): Reordered dispatch
2042 sequence, thereby fixing some comparisons of SCM values with
2045 * numbers.c (scm_divide): Division by zero of inums leads to an
2046 error now. (Formerly, an infinite number was returned.)
2048 Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
2049 if a division has a remainder.
2051 2000-05-02 Gary Houston <ghouston@arglist.com>
2053 * Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).
2055 2000-05-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
2057 * numbers.c (scm_logtest, scm_division): Reordered dispatch
2058 sequence, thereby fixing some comparisons of SCM values with
2061 * numbers.h (scm_makdbl): Mark as deprecated at the point of
2064 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_double2scm,
2065 gh_doubles2scm), numbers.c (scm_istr2flo, scm_max, scm_min,
2066 scm_sum, scm_difference, scm_product, scm_divide, scm_sys_expt,
2067 scm_sys_atan2, scm_make_rectangular, scm_make_polar,
2068 scm_real_part, scm_imag_part, scm_magnitude, scm_angle,
2069 scm_long2num, scm_long_long2num, scm_ulong2num), ramap.c
2070 (ramap_rp, scm_array_map_x), random.c (scm_random,
2071 scm_random_uniform, scm_random_normal_vector_x, scm_random_exp),
2072 struct.c (scm_struct_ref), unif.c (scm_array_to_list): Replace
2073 call to scm_makdbl with a call to scm_make_real or
2074 scm_make_complex, depending on whether the imaginary part is known
2077 2000-05-01 Gary Houston <ghouston@arglist.com>
2079 * scmsigs.c: fix the definition of orig_handlers for the case
2080 that HAVE_SIGACTION is not defined (thanks to
2081 Kalle Olavi Niemitalo).
2083 * Makefile.am: remove include_HEADERS (was libguile.h)
2084 libguile.h: moved to top level directory.
2086 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2088 * numbers.c (SCM_SWAP): Moved to the top of the file to allow for
2091 * numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,
2092 scm_logxor): Reordered dispatch sequence, thereby fixing some
2093 comparisons of SCM values with integer constants.
2095 * number.c (scm_logtest): Removed some redundant SCM_{N}?IMP

2190 the root build directory.
2192 * numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG

2221 * gc.c (which_seg): Use SCM2PTR to convert a non immediate SCM

2462 * objects.h: Don't redeclare scm_call_generic_0 and

2501 * validate.h: move async validation macros to async.c (nobody else
2502 needs them anyway), and rename them.
2504 2000-04-04 Michael Livshin <mlivshin@bigfoot.com>
2506 * async.h: kill the scm_async_t struct. having a heap cell
2507 pretending to be a C struct is not helthy, and is not needed here

2577 * guardians.c (scm_guardian_zombify): mark all zombies in a
2578 separate loop after processing all the currently known live
2579 guardians, so as to not introduce order dependencies (thanks to
2580 Gary Houston). note that the order problems are still there if
2581 some guardians are themselves zombies, but that's a sick case that
2582 I'm not going to worry about.
2583 also, make another outer loop to process zombified
2584 guardians (which are uncovered while marking zombies).

2672 * guardians.c (TCONC_IN, scm_make_guardian): set the CDR of the
2673 empty tconc pair to SCM_EOL instead of SCM_BOOL_F, avoiding the
2674 use of an improper list (which breaks g_print. g_print isn't
2676 guardians.c: Added more comments and modified the make-guardian
2677 docstring. Reordered a few procedures.

2730 coop_mother, coop_child): New variables.
2731 (mother): New function.
2732 (coop_create): New thread spawning mechanism which uses a "mother
2733 thread". The "dummy" pthreads aren't healthy enough to give birth
2734 to new threads since Linux threads thinks they are asleep.
2736 * coop-defs.h (struct coop_t): Removed dummy_mutex.
2738 * coop-defs.h, coop-threads.c (struct coop_t): Eliminate
2739 `sto'-field when GUILE_PTHREAD_COMPAT is enabled.

2743 * arbiters.c (scm_make_arbiter), async.c (scm_async), dynwind.c
2744 (scm_internal_dynamic_wind): Smob data is always of type
2747 * arbiters.c (SCM_ARB_LOCKED, SCM_LOCK_ARB, SCM_UNLOCK_ARB):
2748 Access the locking information in cell entry 0 with
2749 SCM_{SET_}?CELL_WORD_0 instead of SCM_*CAR.

2768 SCM value is equal to #t or #f.
2770 * eq.c (scm_eqv_p, scm_equal_p): Don't use SCM_CAR to access the
2771 cell type entry of non immediate objects of unknown type. Use

2789 * coop.c (coop_create): Set `specific' field, not `data' to NULL.
2791 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2793 * smob.h (SCM_NEWSMOB, SCM_NEWSMOB2, SCM_NEWSMOB3, SCM_SMOB_DATA,
2794 SCM_SET_SMOB_DATA, SCM_TC2SMOBNUM, SCM_SMOBNUM): To access smob
2795 data, use SCM_{SET_}?CELL_TYPE or SCM_{SET_}?WORD_[1-3].
2797 Note that this implies that smob data has always to be passed as
2798 values of type scm_bits_t.
2800 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2802 * threads.c (scm_init_threads): Pass 0 size to scm_make_smob_type
2803 for scm_tc16_thread. As the current COOP threads are written, GC
2804 is not supposed to manage storage for threads.
2806 * error.c (scm_error): Don't try to throw an error if
2807 scm_gc_heap_lock is true.
2809 * coop.c (coop_finish): New function. Called at exit.
2810 (coop_aborthelp): Free thread structures when threads die.
2811 Finished LinuxThreads compatibility support => COOP threads now
2812 mesh with LinuxThreads.

2825 (SCM_NULLP, SCM_NNULLP): Use SCM_EQ_P to compare SCM values.
2827 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2829 * continuations.h (SCM_CONTREGS, SCM_SET_CONTREGS): New macros to
2830 access continuation data.
2832 (SCM_SETJMPBUF): Deprecated. Use SCM_SET_CONTREGS instead.
2834 (SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE, SCM_BASE, SCM_SEQ,
2835 SCM_DFRAME): Use SCM_CONTREGS instead of SCM_CHARS to access
2838 * continuations.c (scm_make_cont), init.c (start_stack),
2839 root.c (scm_internal_cwdr): Use SCM_SET_CONTREGS instead of
2842 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2844 * symbols.h (SCM_LENGTH, SCM_SETLENGTH): Access the length field
2845 of strings and symbols by using SCM_{SET_}?CELL_WORD_0.
2847 (SCM_CHARS, SCM_UCHARS, SCM_SETCHARS): Use SCM_{SET_}?CELL_WORD_1
2848 to access the char * field of strings and symbols.
2850 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2852 * gc.h (SCM_NEWCELL, SCM_NEWCELL2): Use SCM_SET_CELL_TYPE to set
2853 the type entry of a new cell. Added a comment about things to
2854 remember when updating the list of free cells.
2856 (SCM_FREEP, SCM_MARKEDP): Use SCM_CELL_TYPE to access the type
2859 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2861 * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR): Use
2862 SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT. This change implies that
2863 with strict type checking enabled these macros will only work if
2864 given valid SCM parameters.
2866 (SCM_GCCDR): Moved to tags.h.
2868 * tags.h (SCM_GCCDR): Moved here from pairs.h.
2870 2000-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
2872 * tags.h (SCM2PTR, PTR2SCM): Moved to gc.h.
2874 * pairs.h (scm_cell, SCM_CELLPTR, SCM_CELL_WORD*, SCM_CELL_OBJECT*,
2875 SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*, SCM_CELL_TYPE,
2876 SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK, SCM_PTR_GT,
2877 SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC, SCM_NEWCELL,
2878 SCM_NEWCELL2): Moved to gc.h.
2880 (SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR, SCM_SETAND_CDR,
2881 SCM_SETOR_CAR, SCM_SETOR_CDR): Moved to gc.h. These names should
2882 be changed, though, since the macros are not only pair related.
2886 * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,
2887 SCM_CELL_OBJECT*, SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*,
2888 SCM_CELL_TYPE, SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK,
2889 SCM_PTR_GT, SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC,
2890 SCM_NEWCELL, SCM_NEWCELL2, SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR,
2891 SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR): Moved here from
2894 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2896 * tags.h (SCM_STRICT_TYPING): New macro that, if defined,
2897 activates strict compile time type checking for variables of
2899 (SCM, SCM_PACK, SCM_UNPACK): Define according to whether
2900 SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
2901 (SCM_EQ_P): Defined as a macro equivalent for eq?.
2903 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2905 * tags.h (SCM_POINTERS_MUNGED): Removed.
2907 * gc.c (scm_gc_sweep, init_heap_seg): Removed use of
2908 SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
2910 2000-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
2912 * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
2913 SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
2914 SCM_SET_CELL_TYPE): Added a set of low level macros for accessing
2916 (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
2918 * procs.h, procs.c: Instead of SCM_{SET_}?CELL_WORD[12], use the
2919 newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
2921 2000-03-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2923 * tags.h: Disabled definition of SCM_VOIDP_TEST.
2925 Defining SCM as void * introduces problems which haven't been
2926 handled yet. Developers who work with these issues can enable it
2927 in their working copies.
2929 Disabling this definition exposes a set of newly introduced and
2930 older misuses of types which causes warning messages during
2931 compilation. We'll fix this successively.
2933 * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
2934 in order to obtain a value of type SCM.
2935 (scm_cellp): Updated with new changes to scm_mark_locations.
2937 * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
2939 * continuations.c (scm_make_cont): Removed cast of size_t into
2942 * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
2944 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2946 * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for
2947 shifting, not constant. Thanks to Dale P. Smith.
2949 * numbers.c (scm_sum, scm_difference): Don't test a SCM value
2950 for being less than zero. Decode it to a C value first. Again,
2953 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2955 * numbers.h, ramap.c, struct.h, vectors.h: Don't use SCM2PTR for
2956 non scheme values. If raw data is stored in SCM variables, it has
2957 to be accessed using SCM_UNPACK until a better solution is found.
2959 2000-03-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2961 * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
2962 pointer-arithmetic induced by the SCM_PACK/UNPACK change.
2964 * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
2966 * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
2968 * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
2970 * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
2972 * async.c, __scm.h: Removed lots of the old async click logic. It
2973 is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
2974 __scm.h. Let's try this out and dump the old code after the
2975 threads reorganization.
2976 (set-tick-rate, set-switch-rate): Conditionally removed.
2978 2000-03-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2980 * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
2981 made SCM values into pointers. This turned an arithmetic
2982 computation of the address of the vcell into a pointer-arithmetic
2983 one, thereby screwing up marking of structs.
2984 Bugfix 2: Removed incompletely introduced loop variable `j' used
2985 when protecting the tail array of a struct.
2987 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2989 * struct.h (SCM_STRUCT_DATA): Don't cast SCM values to pointers.
2991 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2993 * symbols.h, symbols.c (scm_strhash): Declare the string
2994 parameter as constant, since it is not modified.
2996 * symbols.c (scm_intern_obarray_soft,
2997 scm_sysintern0_no_module_lookup): Can now pass constant strings
2998 to scm_strhash without need for casting.
3000 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
3002 * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS): Don't cast SCM
3003 values to pointers. Use SCM2PTR instead.
3005 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
3007 * async.c (scm_set_tick_rate, scm_set_switch_rate): Don't unpack
3008 results of SCM_INUM.
3010 2000-03-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3012 * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
3013 GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
3014 GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
3016 * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
3017 min_yield_fraction, min_yield, adjust_min_yield): Renamed from
3018 SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
3019 gc_trigger, adjust_gc_trigger.
3021 * gc.c (alloc_some_heap): Further improvement of minimal heap size
3023 (SCM_MAX): New macro.
3024 (scm_freelist_t): New field: collected_1. Previous amount of
3026 (gc_sweep_freelist_finish): Trigger based on two last values of
3027 freelist->collected to avoid unnecessary allocation due to
3029 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
3030 Adjusted to 45000 cells, 40% and 40%. Gives quick startup
3031 without extra heap allocation.
3033 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
3035 * numbers.h (SCM_MAKINUM): The parameter to SCM_MAKINUM should
3036 already be a C value. No need to unpack it.
3038 * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t
3039 if we know it fits into an inum.
3041 * ramap.c (ramap_rp): An scm_tc7_[ui]vect object does point to a
3042 field of long values. In contrast, SCM_VELTS accesses a field of
3045 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3047 * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
3049 (scm_gc_yield_1): New variable: Holds previous yield. Used to
3050 make better judgements.
3051 (gc_sweep_freelist_finish): Inserted explanation of use of
3054 * print.h, stacks.h, options.c, options.h: Changed C++
3057 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
3059 * tags.h (SCM2PTR, PTR2SCM): Use SCM_PACK / SCM_UNPACK correctly.
3061 * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
3062 SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS): Use SCM_PACK /
3063 SCM_UNPACK / SCM2PTR correctly.
3065 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3067 * gc.c (adjust_gc_trigger): Improved documentation.
3068 (alloc_some_heap): Since gc_trigger is used against
3069 freelist->collected, this is the value which should be used to
3070 predict minimum growth.
3072 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
3074 * eval.h: Fix mixup of packed/unpacked SCM values. (Thanks
3075 Thien-Thi Nguyen for the patch.)
3077 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
3079 * numbers.c (scm_ash): Fixed typing problems with the second
3080 parameter and added some documentation. (Thanks Thien-Thi Nguyen
3081 for indicating the problem.)
3083 2000-03-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3085 * gc.c, gc.h (scm_gc_yield): New variable.
3086 (adjust_gc_trigger): Use scm_gc_yield.
3087 (alloc_some_heap): Use scm_gc_yield instead of
3088 scm_gc_cells_collected.
3090 * coop-threads.c: Addd #include "root.h", #include "strings.h".
3092 * debug.c: Added #include "root.h". (Thanks to Thien-Thi Nguyen.)
3094 * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
3095 trigger adjustmeant: Take yield (freed cells) for all freelists
3097 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
3098 to 50000 cell heap with 45% trigger.
3099 (scm_gc_cells_collected): Reintroduced.
3100 (SCM_HEAP_SIZE): New macro.
3101 (scm_gc_sweep): Reintroduced correct computation of
3102 scm_cells_allocated.
3103 (scm_freelist_t): Corrected commentary for field `cluster_size':
3104 Clustersize counts objects, not cells; New member
3105 `clusters_allocated'.
3107 2000-03-19 Michael Livshin <mlivshin@bigfoot.com>
3109 * *.[hc]: add Emacs magic at the end of file, to ensure GNU
3112 2000-03-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3114 * threads.h: Added #include "libguile/throw.h". (Thanks to
3117 2000-03-18 Michael Livshin <mlivshin@bigfoot.com>
3119 * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
3120 names, anyone got any better ones?)
3122 * gc.h: (typedef struct scm_freelist_t) remove from here.
3124 * gc.c: (CELL_UP, CELL_DN) made these macros take additional
3125 parameter (the span).
3126 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
3127 (typedef struct scm_freelist_t) moved here from gc.h, it had no
3128 business being externally visible.
3129 (typedef struct scm_heap_seg_data_t) renamed from
3130 scm_heap_seg_data, to be style-compliant.
3131 (scm_mark_locations) if the possible pointer points to a
3132 double-cell, check that it's properly aligned.
3133 (init_heap_seg) align double-cells properly, work with the
3134 assumption that the segment size divides cleanly by cluster size.
3135 (round_to_cluster_size) new function.
3136 (alloc_some_heap, make_initial_segment) use round_to_cluster_size
3137 to satisfy the new init_heap_seg invariant.

3196 2000-03-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3198 * gc.c, gc.h: Cleanup of the change of 2000-03-15.
3199 Cluster sizes are now independent of GC trigger values.
3200 GUILE_GC_TRIGGER_n can now specify a relative trigger value:
3201 A negative integer gives fraction of total heap size in percent.
3202 (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
3204 * init.c (scm_boot_guile_1): Introduced new variable
3205 GUILE_MAX_SEGMENT_SIZE; New environment variable names:
3206 GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
3207 GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
3209 2000-03-16 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3211 * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
3212 freeing of segment work with the new GC scheme. (Thanks to
3213 Michael Livshin.) Oops, also happened to make GUILE_NEW_GC_SCHEME
3214 the default, but I'll let this change stay in CVS Guile since this
3215 code is not expected to contain serious bugs.
3217 2000-03-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3219 * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
3221 (scm_free_list_length): New procedure (GUILE_DEBUG).
3222 Fixed a small but serious bug introduced by the previous change.
3224 * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
3225 loop and declare as register.
3227 * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
3230 Wed Mar 15 08:27:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3232 * fluids.c: Docstring patch from Keisuke Nishida. Some
3233 reindentation, too, and a couple formals renamed. Should
3234 fluid-set! return UNSPECIFIED instead of a value?
3236 Wed Mar 15 08:24:58 2000 Greg J. Badros <gjb@cs.washington.edu>
3238 * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
3239 generate the latter from the concrete listing of the former. Then
3240 make guile-procedures.txt depend on DOT_DOC_FILES instead of
3241 *.doc, so that rebuilding it works.
3243 Wed Mar 15 08:12:14 2000 Greg J. Badros <gjb@cs.washington.edu>
3245 * libguile.h: Include libguile/validate.h. Thanks Keisuke Nishida!
3247 * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
3248 with nothing and \n, respectively. Thanks Keisuke Nishida for
3249 noticing this problem.
3251 2000-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3253 * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
3254 new way of allocating heap. It makes Guile fast, but still
3257 * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
3258 allocating heap. The basic idea is to trigger GC every Nth
3259 allocated cell and grow heap when free list runs out. The scheme
3260 has been extended so that GC isn't triggered until all remaining
3261 cells are used. The implementation is also prepared for
3262 development in the direction of POSIX threads.
3264 * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
3265 SCM_EXPHEAP should return half of the heap size.
3267 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3269 The following change to init.c is only enabled if Guile was
3270 configured with --enable-guile-debug.
3272 * init.c (scm_i_getenv_int): New function.
3273 (scm_boot_guile_1): Use the environment variables
3274 GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
3275 they exist. (This may be replaced by a Scheme level mechanism in
3278 * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
3279 scm_assoc. (Thanks to Keisuke Nishida.)
3281 2000-03-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3283 * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
3284 scm_nil, scm_t. (Thanks to Keisuke Nishida.)
3286 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3288 * init.c (scm_boot_guile_1): Use same initial segment size for
3289 1-word and 2-word segments. Having the smaller size causes Guile
3290 to GC too often. Obviously something needs to be done to allow
3291 for a smaller 2-word segment without this to happen. (The amount
3292 of heap for each type should be automatically adapted to the
3293 application somehow.)
3295 [Almost all of these changes should be documented in the NEWS
3298 * gc.h (scm_freelist_t): New type.
3300 * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
3302 * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
3303 all of Guile basics fits into one segment and there suitable room
3305 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
3307 (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
3308 Freelists now contains information about object span, cells
3309 collected and amount of cells in heap segments belonging to the
3311 (scm_heap_size, scm_gc_cells_collected): Removed.
3313 * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
3315 * Makefile.am (libguile_la_LDFLAGS): Bumped library version
3318 * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
3319 numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
3320 rewrite of handling of real and complex numbers.
3321 (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
3322 removed along with the support for floats. (Float vectors are
3325 * tags.h (scm_tcs_bignums): Removed.
3326 (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
3327 Use SCM_BIGSIGN(x) to test for sign!
3328 (scm_tc16_big): The new bignum type.
3329 (SCM_REAL_PART, SCM_IMAG_PART): Removed.
3331 * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
3332 (scm_makdbl): Deprecated.
3333 (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
3334 (SCM_SINGP): Deprecated.
3336 (SCM_INEXP, SCM_CPLXP): Deprecated.
3337 (SCM_INEXACTP, SCM_COMPLEXP): New macros.
3338 (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
3339 SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
3340 (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
3341 for doubles and complex numbers.
3342 (SCM_REAL_VALUE): New selector for doubles.
3343 (scm_double_t, scm_complex_t): New types.
3346 * numbers.c (scm_floprint, scm_floequal): Removed.
3347 (scm_print_real, scm_print_complex, scm_real_equalp,
3348 scm_complex_equalp): New functions.
3350 * unif.c (scm_makflo): Removed.
3352 * smob.h (SCM_SMOB_PREDICATE): New macro.
3353 (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
3354 SCM_RETURN_NEWSMOB3): New macros.
3356 1999-11-21 Michael Livshin <mlivshin@bigfoot.com>
3358 The following changes implement primitive support for double cells
3359 (i.e. four-word cells) and change the representation of some
3360 things to multi-cells instead of cons+malloc. (Applied and
3363 * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
3364 (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
3365 multi-cell access macros (used by the ones below).
3366 (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
3369 * gc.c (scm_freelist2): multi-cell freelists.
3370 (inner_map_free_list): map_free_list, parameterized on ncells.
3371 "nn cells in segment mm" was misleading for ncells > 1; changed to
3372 "objects". still print cells too, though.
3373 (scm_map_free_list): rewritten using inner_map_free_list.
3374 (scm_check_freelist): get freelist as parameter, since now we have
3376 (scm_debug_newcell2): multi-cell variants of
3378 (scm_gc_for_newcell): take ncells and freelist pointer as
3380 (scm_gc_mark): add case for tc7_pws (procedures with setters are
3382 (scm_gc_sweep): don't free the float data, since it's not malloced
3384 (init_heap_seg): didn't understand what n_new_objects stood for,
3385 so changed to n_new_cells.
3386 (make_initial_segment): new function, makes an initial segment
3387 according to given ncells.
3388 (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
3390 * numbers.c (scm_makdbl): no malloc'ing needed, so the
3391 {DEFER,ALLOW}_INTS thing removed.
3393 * numbers.h (struct scm_dbl): changed to represent a double cell,
3394 with the number in the second half.
3396 * dynwind.c: changed the wind-guards representation to double
3399 * procs.c, procs.h: changed the procedure-with-setter representation
3402 * async.c, async.h: made async representation a double cell.
3404 * dynl.c: made dynamic_obj representation a double cell.
3406 2000-03-13 Gary Houston <ghouston@arglist.com>
3408 * ports.c (flush_void_port): renamed to flush_port_default.
3409 (end_input_void_port): renamed to end_input_default.
3411 * init.c (scm_standard_stream_to_port): create a void port instead
3412 of opening /dev/null if the standard file descriptors are bad.
3413 advantages: no portability problems, doesn't waste a file descriptor,
3414 simplifies the code (thanks to Marius for the idea).
3416 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
3418 * void ports: make reading from a void port give EOF instead of
3420 * ports.c (s_scm_sys_make_void_port): modified docstring.
3421 (fill_input_void_port): new proc.
3422 (scm_init_ports): set up fill_input_void_port.
3423 * ports.c (scm_port_non_buffer): new proc.
3424 (scm_void_port): call scm_port_non_buffer.
3426 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
3427 which was incorrectly appended.
3429 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3431 * guile-doc-snarf.in: Don't use absolute path for `sed'. (Note
3432 that we can't use autoconf for this. Autoconf itself relies on
3433 the existence of `sed' somewhere on your path.) (Thanks to Dirk
3436 2000-03-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3438 * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
3439 EXTRA_libguile_la_SOURCES.
3441 * iselect.h: Always declare scm_internal_select.
3443 * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
3444 end. Also let scm_internal_select be a real function also when
3447 * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
3449 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3451 * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
3452 SCM_ASYNC_TICK. (This is a preparation for POSIX threads support,
3453 and kind of an experiment: Will this cause problems?)
3455 Sun Mar 12 13:26:30 2000 Greg J. Badros <gjb@cs.washington.edu>
3457 * Makefile.am: Added *.doc to DISTCLEANFILES.
3459 2000-03-12 Gary Houston <ghouston@arglist.com>
3461 * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
3462 the fdes is valid before doing anything else. check that
3463 the file descriptor supports the modes required.
3464 (scm_fport_buffer_add): don't throw an error if fstat doesn't
3465 work: just use the default buffer size.
3467 * throw.c: change an outdated comment about scm_internal_catch
3468 BODY: it doesn't take a jumpbuf arg.
3470 * init.c (scm_standard_stream_to_port): install a handler in case
3471 scm_fdes_to_port throws an error. don't check here whether the
3472 file descriptor is valid, since scm_fdes_to_port will do that.
3473 set the revealed count depending on whether the port got the
3474 standard file descriptor.
3475 (stream_body_data): new type.
3476 (stream_body, stream_handler): new procs.
3478 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3480 * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
3481 Renamed from SCMWORD.
3483 * tags.h (SCM_NCELLP): Removed (SCMWORD).
3485 * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
3487 * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
3488 feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,

3493 throw.c, unif.c, unif.h, variable.h, vectors.h, weaks.c,
3494 weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
3495 SCM_ASSCM, SCM_ASWORD, SCM_CARW).
3497 * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
3499 * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
3500 tags.h: Fixed copyright notices.
3502 * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
3504 2000-03-12 Marius Vollmer <mvo@zagadka.ping.de>
3506 * init.c (scm_standard_stream_to_port): Check whether the file
3507 descriptor is valid and substitute "/dev/null" when not.
3509 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3511 * coop-defs.h (struct timespec): Conditionally defined.
3513 * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
3516 * readline.c (match_paren): Bugfix: First arg to select is not
3517 number of descriptors but the number of the highest descriptor +
3520 This is a preliminary attempt at a cleanup of the threads support
3521 code. It moves things to better places, makes arguments more
3522 consistent with the POSIX API (which is used in GNOME's glib), and
3523 adds new functionality.
3525 * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
3527 * coop-defs.h (scm_mutex_trylock): New macro: alias for
3529 (scm_cond_init): Changed definition to
3530 coop_new_condition_variable_init.
3532 * coop.c: #include <errno.h>
3533 (coop_timeout_qinsert): Moved here from iselect.c
3534 (coop_new_mutex_init, coop_new_condition_variable_init): New
3535 functions. The strange names are temporary. Use scm_mutex_init
3536 and scm_cond_init instead.
3537 (coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
3538 is ANSI C, but should we check for individual error codes in
3540 (coop_condition_variable_timed_wait_mutex): New function.
3541 (coop_key_create, coop_setspecific, coop_getspecific,
3542 coop_key_delete): New functions.
3544 * iselect.c (coop_timout_qinsert): Moved to coop.c
3546 2000-03-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3548 * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
3549 SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
3551 * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
3554 * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
3555 SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
3556 proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
3558 * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
3561 2000-03-11 Dale P. Smith <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
3563 * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
3564 scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
3565 logical functions from SCM.
3567 (logand, logior, logxor, logtest, logbit?): Extended scheme
3568 logical functions to use bignums from SCM.
3570 (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
3571 lognot from using bignums.
3573 Thu Mar 9 11:33:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3575 * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
3576 eliminating some warnings.
3578 * unif.c, strports.c, print.c, options.c: Fix some warnings on
3581 * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
3582 what the scm_return_first* functions do.
3584 2000-03-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
3586 * libguile/*.[ch]: make a distinction between SCM as a generic
3587 name for a Scheme object (now a void*), and SCM as 32 bit word for
3588 storing tags and immediates (now a long int). Introduced
3589 SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
3590 code in the process: arbiter.c (use macros), unif.c (scm_array_p),
3592 Wed Mar 8 10:15:59 2000 Greg J. Badros <gjb@cs.washington.edu>
3594 * numbers.c: Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
3595 various logXXX primitives. Thanks Eric Moore!
3597 Tue Mar 7 08:05:22 2000 Greg J. Badros <gjb@cs.washington.edu>
3599 * run-test, remaining-docs-needed: Added these scripts. The
3600 second one is only temporary until the docstring additions are
3601 complete. run-test may best live on, but is here mostly for
3602 convenience and awareness for now.
3604 * hash.c: Docs, minor cleanup patch from Dirk Herrman.
3606 Thu Mar 2 16:06:58 2000 Greg J. Badros <gjb@cs.washington.edu>
3608 * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
3609 displaying the expected type. Use SCM_LISTn in a couple places
3610 instead of scm_cons-ing by hand.
3612 * __scm.h: Added SCM_ASSERT_TYPE macro.
3614 * validate.h, scm_validate.h: Added the former, as a renamed
3615 version of the latter with SCM_ASSERT_TYPE used in
3616 SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
3618 * Makefile.am: Rename scm_validate.h to validate.h.
3620 * *.c, *.h: Include validate.h, not scm_validate.h (old name's
3621 prefix was superfluous).
3623 Thu Mar 2 15:33:12 2000 Greg J. Badros <gjb@cs.washington.edu>
3625 * hashtab.c: Improved documentation for lots of functions. Added
3626 handwritten docs for `hash-fold'.
3628 Thu Mar 2 15:13:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3630 * list.c: Added hand-written docs for `del{q,v,ete}1!'.
3632 Thu Mar 2 12:38:30 2000 Greg J. Badros <gjb@cs.washington.edu>
3634 * list.c: Moved append docs to append! Thanks Dirk Hermann. Also,
3635 added append docs from R4RS.
3637 * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
3638 Thanks Dirk Hermann!
3640 * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
3641 deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
3643 * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
3644 Drop use of SCM_P for function prototypes... assume an ANSI C
3645 compiler. Thanks Dirk Hermann!
3647 Sat Feb 19 12:20:12 2000 Greg J. Badros <gjb@cs.washington.edu>
3649 * ports.c: Made `set-port-column!' and `set-port-line!' each
3650 return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
3651 that caused a seg fault. Also fixed `set-port-column!'s
3652 docstring. Thanks Han-Wen Nienhuys for finding the bug!
3654 Sun Feb 13 19:11:42 2000 Greg J. Badros <gjb@cs.washington.edu>
3656 * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
3657 regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
3658 strings.c, variable.c: Added lots of documentation, cleaned up
3659 some existing documentation. Occasionally changed formal params
3660 to match docs. Also folded an #ifdef into the inners of a
3661 primitive instead of having two copies of the primitive
3662 (`get-internal-real-time', from stime.c)
3664 Sun Feb 13 18:12:19 2000 Greg J. Badros <gjb@cs.washington.edu>
3666 * ports.c: Added docs for primitives missing them. Written by
3669 Sun Feb 13 09:40:36 2000 Greg J. Badros <gjb@cs.washington.edu>
3671 * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
3672 just execing guile-func-name-check. Thanks Michael Livshin!
3674 Thu Feb 10 11:43:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3676 * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
3677 dead code. Patch from Michael Livshin.
3679 * guile-doc-snarf.in: Tweak to work with Sun/HP sh. Patch from
3682 2000-02-09 Gary Houston <ghouston@arglist.com>
3684 * init.c (scm_init_standard_ports): when stdout is a tty, make the
3685 current-output-port unbuffered by default. this is less confusing
3686 for interactive use. it was line-buffered because of a
3687 performance problem with unbuffered ports, but I think it will be
3690 2000-02-08 Gary Houston <ghouston@arglist.com>
3692 * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
3695 * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
3696 HAVE_TZNAME are defined, use an empty string instead of giving two
3697 spurious compile-time errors.
3699 Tue Feb 8 13:57:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3701 * ports.c: Doc patches from Richard Kim. Pasted from MIT Scheme.
3704 Mon Feb 7 09:07:31 2000 Greg J. Badros <gjb@cs.washington.edu>
3706 * macros.c: Doc patches from Richard Kim. Pasted from scm.texi.
3708 Sun Feb 6 20:26:21 2000 Greg J. Badros <gjb@cs.washington.edu>
3710 * pairs.c: Doc patches from Richard Kim. Pasted from MIT Scheme
3711 (which is GNU GPL'd).
3713 2000-01-31 Gary Houston <ghouston@arglist.com>
3715 * strings.h: don't use SCM_P. don't include <string.h>.
3716 * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
3718 * strings.c (scm_string_ref): make the 2nd argument compulsory.
3719 previously it defaulted to zero for no good reason that I can see.
3720 use a local variable for SCM_INUM (k). replace
3721 SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
3723 (scm_makfromstr): cosmetic changes.
3725 (scm_string): Accept only chars in the list, not strings, for
3726 conformance to R5RS (particularly for list->string, which is
3727 supposed to be the inverse of string->list.) remove
3728 SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
3729 scm_makstr handles the cell allocation. when reporting wrong-type
3730 arg, don't report the position as 1.
3732 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
3734 2000-01-29 Gary Houston <ghouston@arglist.com>
3736 * posix.c (scm_pipe): rewrote the docstring.
3738 * filesys.c (scm_select, retrieve_select_type, get_element,
3739 fill_select_type, set_element): modified so that Scheme
3740 "select" tests port buffers for the ability to provide input
3741 or accept output. Previously only the underlying file descriptors
3742 were checked. Rewrote the docstring.
3744 Thu Jan 27 10:14:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3746 * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
3747 from Gregg Reynolds. Thanks Gregg!
3749 Thu Jan 27 09:59:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3751 * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
3752 adding "x" prefix to the line so that guile-func-name-check
3753 doesn't complain unnecessarily.
3755 Wed Jan 26 17:33:52 2000 Greg J. Badros <gjb@cs.washington.edu>
3757 * throw.c: Factor out an #ifdef/#else/#endif choice more finely
3758 for maintainability.
3760 * strop.c: Documentation added by Gregg A. Reynolds. Pasted in
3763 Wed Jan 26 10:02:11 2000 Greg J. Badros <gjb@cs.washington.edu>
3765 * tag.c: Added doc for `tag', but mark as deprecated since Mikael
3766 suggests removing tag.c altogether (and using a new `class-of'
3769 * strings.c: Added documentation from Gregg A. Reynolds. Edited
3770 a bit by me to use FOO instead of @var{foo} and to have the
3771 summary come before preconditions on input. Also dropped trailing
3774 * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
3775 function with scm_make_subr_opt w/ last arg of 0 so it is not
3776 visible at the Scheme level. Mikael says that this is the right
3777 thing because the first arg to the proc is the guts of a compiled
3778 closure and shouldn't be exposed to the Scheme level.
3780 Tue Jan 25 17:15:47 2000 Greg J. Badros <gjb@cs.washington.edu>
3782 * sort.c: typo in comment fixed.
3784 * keywords.c: Added documentation.
3786 * guardians.c: Added documentation (could be better).
3788 * gc.c: Added docs for gc-set-debug-check-freelist.
3790 * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
3792 * boolean.c: Added docs for `not', `boolean?' (by hand).
3794 Tue Jan 25 13:28:56 2000 Greg J. Badros <gjb@cs.washington.edu>
3796 * random.c: Added documentation, from SLIB page:
3797 http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
3799 Mon Jan 24 17:50:20 2000 Greg J. Badros <gjb@cs.washington.edu>
3801 * variable.c, version.c: Added documentation, written by hand
3802 since I could not find anything already written that was
3805 2000-01-23 Gary Houston <ghouston@arglist.com>
3807 * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
3808 not defined (thanks to Richard Y. Kim).
3810 Thu Jan 20 13:00:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3812 * Makefile.in: Removed, this is auto-generated.
3814 Thu Jan 20 11:33:47 2000 Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
3816 * list.c: Put some variable initialization code at the point of
3817 declaration; Added a comment for list*; Formatting changes.
3819 * load.c: use SCM_NNULLP to make sure the end of a list is not
3822 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3824 * backtrace.c (scm_display_error_message): Bugfix: Don't use
3825 result of scm_list_p as C boolean.
3826 (scm_display_error_message, scm_set_print_params_x): Use new
3827 validation macros. (Thanks to Dirk Herrmann.)
3829 * net_db.c (scm_resolv_error): Cast result from hstrerror.
3831 * strports.c (st_end_input): Inserted parenthesis to get operator
3834 * list.h (scm_init_list): Removed SCM_P around prototypes.
3836 * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
3837 filesys.c, posix.c: Converted docstrings to ANSI C format and
3838 escaped " occurring inside string literals.
3840 Tue Jan 18 13:21:08 2000 Mikael Djurfeldt <mdj@r11n07-s.pdc.kth.se>
3842 * posix.c (scm_mknod): Escape " occuring inside docstring.
3844 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3846 * alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,
3847 evalext.c, filesys.c, gc.c, hash.c, hashtab.c, ioext.c,
3848 keywords.c, list.c, load.c, macros.c, net_db.c, numbers.c,
3849 objprop.c, ports.c, posix.c, print.c, procprop.c, procs.c,
3850 ramap.c, regex-posix.c, root.c, scmsigs.c, simpos.c, socket.c,
3851 stacks.c, stime.c, strings.c, strop.c, strports.c, struct.c,
3852 symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
3853 weaks.c: Converted docstrings to ANSI C format.
3855 * filesys.c (scm_chmod), simpos.c (scm_system), version
3856 (scm_version), vports (scm_make_soft_port): Escape " occuring
3859 Mon Jan 17 11:41:22 2000 Greg J. Badros <gjb@cs.washington.edu>
3861 * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
3862 SCM_VALIDATE_LONG_COPY
3864 * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
3865 SCM_VALIDATE_INUM_COPY to let bigger numbers be used. Rename a
3866 couple of formal arguments (and fix their uses) to make arguments
3867 match the documentation.
3869 2000-01-14 <mstachow@alum.mit.edu>
3871 * Makefile.am: Augment path when running guile-doc-snarf so
3872 guile-func-name-check is found.
3874 Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
3876 * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
3877 def, not SCM_MAKINUM(def); thanks Janis Bzerins!
3879 Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3881 * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
3882 the way guile-1.3.4 worked, but #if 0 out the version using
3883 SCM_VALIDATE_INUM_COPY for stricter testing.
3885 Tue Jan 11 18:24:18 2000 Greg J. Badros <gjb@cs.washington.edu>
3887 * guile-doc-snarf.in: Use new $fullfilename for running
3888 guile-func-name-check, and put "$fullfilename" and "$filename" in
3889 quotes at uses to make sure re-splitting on whitespace does not
3890 occur (so filenames w/ embedded whitespace would work okay, though
3891 I sure hope we never have to deal with that! :-) ). Thanks to
3892 Mikael for pointing out the source_dir != build_dir was broken.
3894 Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
3896 * scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
3897 SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
3898 SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
3899 macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
3902 * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
3903 then return whether it's an open port (was validating that it was
3904 an open port -- this was a bug I introduced back in December, but
3905 my careful reading of diffs caught it).
3907 * numbers.c: Recombine the two conditional-compilation paths for
3908 all the log* primitives -- they were split based on #ifndef
3909 scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
3910 some bugs and inconsistencies in the two sets of implementations.
3911 (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
3913 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
3914 SCM_VALIDATE_INUM_COPY once where it should've been used.
3916 * fluids.c (scm_internal_with_fluids): Use
3917 SCM_VALIDATE_LIST_COPYLEN.
3919 * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
3920 this is questionable as it relaxes type safety, but other changes
3921 were useful and all SCM_NUM2LONG's should probably be
3922 revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
3924 * evalext.c: line-break change on 1 line.
3926 * eval.c (nconc2last): Takes a non-empty list as its first
3927 argument, not just a list.
3929 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
3931 Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3933 * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
3934 net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
3937 * symbols.c (scm_sysintern0): Fixed the function name in a
3938 scm_misc_error invocation.
3940 * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
3941 use scm_return_first to ward off latent GC bug that Mikael caught.
3943 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
3944 used before but should've been.
3946 2000-01-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3948 * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
3949 SCM_FUNC_CAST_ARBITRARY_ARGS.
3951 Tue Jan 11 13:44:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3953 * guile-func-name-check.in: Added this script to statically check
3954 #define FUNC_NAME, #undef FUNC_NAME in the source.
3956 * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
3957 redundant comment, semicolon; caught by new guile-func-name-check
3960 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
3961 Caught by new guile-func-name-check-script.
3963 * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
3965 * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
3966 guile-func-name-check.
3968 * guile-doc-snarf.in: Run guile-func-name-check on the file before
3971 Tue Jan 11 11:31:10 2000 Greg J. Badros <gjb@cs.washington.edu>
3973 * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
3974 port function take const void*, not void*.
3976 Tue Jan 11 11:18:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3978 * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
3979 strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
3980 SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
3981 consistency with the other macros dealing with immediate
3982 characters. (Similar to INT -> INUM change a week or so ago).
3984 Tue Jan 11 10:41:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3986 * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
3987 net_db.c, read.c, socket.c: Update error messages to use ~A for
3988 %s, ~S for %S to work with new `simple-format' format and be
3989 standardized better.
3991 * print.h, print.c (scm_simple_format): Added `simple-format'
3992 primitive. It's the old scm_display_error, with ARGS now a rest
3993 parameter, and the destination first instead of last (and a couple
3994 new capabilities inspired by `format' -- #t as destination means
3995 current-output-port, #f means return the formatted text as a
3998 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
4000 * backtrace.c (scm_display_error_message): Rewrote to use
4001 scm_simple_format() procedure.
4003 * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
4005 2000-01-09 Marius Vollmer <mvo@zagadka.ping.de>
4007 Finally applied the libltdl patch from Thomas Tanner, with slight
4010 * DYNAMIC-LINKING: Removed because it is obsolete.
4011 * dynl.c: Use ANSI prototypes.
4012 (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
4013 * scmconfig.h.in: Do not change, as it is automatically generated.
4015 1999-07-25 Thomas Tanner <tanner@ffii.org>
4017 * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
4019 * Makefile.am: likewise, add INCLTDL (libltdl headers) to
4020 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
4022 * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
4023 * guile.c: register preloaded modules
4024 * scmconfig.h.in: remove obsolete symbols
4026 2000-01-09 Gary Houston <ghouston@arglist.com>
4028 * These changes should make it unnecessary to call tzset from
4029 Scheme after modifying the TZ environment variable, even if the
4030 system date facilities cache the value.
4031 * stime.c (setzone, scm_localtime): added comments.
4032 (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
4033 (setzone): don't call tzset.
4034 (restorezone): call tzset only if HAVE_TZSET is defined.
4035 (scm_tzset): don't define if HAVE_TZSET not defined. Change the
4036 doc string to indicate that this procedure isn't likely to do
4038 (scm_localtime, scm_strftime, scm_mktime): call tzset if
4039 LOCALTIME_CACHE is defined.
4041 2000-01-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
4043 * posix.c (scm_sync): Return SCM_UNSPECIFIED.
4045 2000-01-09 Gary Houston <ghouston@arglist.com>
4047 * eval.c: define scm_unbound_variable_key ('unbound-variable).
4048 scm_lookupcar1: throw an error with key 'unbound-variable instead
4049 of 'misc-error when an unbound variable is encountered.
4051 * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
4052 scm_symlink, scm_readlink, scm_lstat),
4053 posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
4054 scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
4056 simpos.c (scm_system),
4057 stime.c (scm_times, scm_strptime):
4058 move the HAVE_XXX feature tests out of the procedure bodies.
4059 don't use SCM_SYSMISSING.
4060 scm_validate.h (SCM_SYSMISSING): removed.
4061 error.h, error.c (scm_sysmissing): comment that this is deprecated.
4062 see ChangeLog entry for 1999-12-28.
4064 Sat Jan 8 19:52:04 2000 Greg J. Badros <gjb@cs.washington.edu>
4066 * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
4068 Sat Jan 8 17:06:46 2000 Greg J. Badros <gjb@cs.washington.edu>
4070 * backtrace.c: Fix spelling typo in a comment.
4072 * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
4073 text. Reformatted some of the expansions.
4075 Fri Jan 7 15:50:46 2000 Greg J. Badros <gjb@cs.washington.edu>
4077 * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
4078 report the position of the argument.
4080 * error.h, error.c (scm_out_of_range_pos): Added this function to
4081 take extra "pos" argument, the position number of the errant
4084 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
4086 * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
4087 and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
4088 prefers that and I'm reasonably indifferent.
4090 Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
4092 * snarf.h: Factor out differences between C++ and non-C++ into
4093 SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
4094 definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
4095 Mikael's macros, below, but changed names and SCM_SNARFING no
4096 longer expands to include %%% -- that must appear in the argument
4097 so that the token appears at the call-site as a reminder).
4099 2000-01-07 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
4101 * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
4102 snarf macro definitions.
4104 2000-01-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4106 * chars.c (scm_integer_to_char): Use Greg's nice
4107 SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
4110 Thu Jan 6 11:48:49 2000 Greg J. Badros <gjb@cs.washington.edu>
4112 * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
4114 Thu Jan 6 11:22:53 2000 Greg J. Badros <gjb@cs.washington.edu>
4116 * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
4117 instead of GUILE_PROC.
4119 Thu Jan 6 11:21:49 2000 Greg J. Badros <gjb@cs.washington.edu>
4121 * alist.c: Do not report mismatch errors on some uses of `tmp' (do
4122 this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
4125 Thu Jan 6 09:54:33 2000 Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
4127 * scm_validate.h: Remove some redundant NIMP tests.
4129 * alist.c: minimize scope of the tmp variables, and initialize
4130 them when declared. The strange SCM_NIMP tests are replaced by
4131 SCM_CONSP tests that more closely reflect the intended semantics.
4132 However, we don't get a performance penalty here, because the
4133 SCM_CONSP test was performed by the ALISTCELL test anyway. * The
4134 extremely ugly use of ASRTGO macros was removed: The calls to
4135 ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
4136 label parameter that only exists when SCM_RECKLESS is not defined.
4137 This works, because ASRTGO itself is defined in a way that it only
4138 makes use of the label parameter if SCM_RECKLESS is not defined
4139 (shudder!). Does guile make at all use of the possibility to
4140 define SCM_RECKLESS? * Codesize is likely to be reduced, since
4141 instead of two calls to SCM_ASSERT performed by the ALISTCELL test
4142 we now only get one test.
4144 * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
4145 SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
4146 some variables in `list?'. Fix `reverse' and `reverse!'
4147 primitives to handle improper lists better.
4149 Wed Jan 5 11:24:53 2000 Greg J. Badros <gjb@cs.washington.edu>
4151 * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
4152 macros and SCM_DEFINE macros to match GNU coding standards.
4154 Wed Jan 5 11:04:24 2000 Greg J. Badros <gjb@cs.washington.edu>
4156 * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
4158 Wed Jan 5 10:59:06 2000 Greg J. Badros <gjb@cs.washington.edu>
4160 * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
4161 better consistency with the names of other SCM_VALIDATE_ macros
4162 and better conformance to guile naming policy.
4164 Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
4166 * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
4167 SCM_VALIDATE instead of 1 to avoid a check on the argument (since
4168 it's not the actual name of the formal).
4170 * guile-snarf.awk.in: Do argument/number mismatch checking and
4171 print warnings in an Emacs compile-mode parseable format.
4173 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
4174 SCM_OUTOFRANGE as 3rd argument.
4176 * random.c: Fix argument/number mismatch (that I introduced :-( ).
4178 * __scm.h: Do not #define SCM_ARG* when snarfing;
4179 lets us distinguish between 1 and SCM_ARG1 when snarfing as only
4180 the former (using the number) requires the argument to match the
4181 formal in the current argument snarfing check.
4183 * snarf.h: Give new definition of SCM_ASSERT when in
4184 snarfing mode to output a lexically-identifiable sequence that the
4185 guile-snarf.awk script uses to verify argument/position matching.
4187 * ramap.c: Remove extraneous #undef FUNC_NAME.
4189 Wed Jan 5 08:36:38 2000 Greg J. Badros <gjb@cs.washington.edu>
4191 * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
4192 current version of the same functionality; it writes the .x output
4193 to stdout instead of directly into the file.
4195 Wed Jan 5 08:15:04 2000 Greg J. Badros <gjb@cs.washington.edu>
4197 * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
4198 posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
4199 redundant with the safer macros. Patch from Dirk Hermann applied
4200 by hand. Thanks Dirk!
4202 * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
4205 * ramap.c: whitespace change.
4207 Tue Jan 4 14:21:35 2000 Greg J. Badros <gjb@cs.washington.edu>
4209 * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
4210 removals from Dirk Hermann.
4212 * alist.c: Rename formals to match the parameter names in the
4213 documentation, updates to documentation. Thanks Dirk Hermann!
4215 2000-01-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4217 * eval.c (SCM_CEVAL): Reverse order of
4218 scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
4219 (Thanks to Brad Knotwell.)
4221 Mon Jan 3 08:30:02 2000 Greg Harvey <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
4223 * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
4226 * pairs.h: Added a comment about the need for the SCM_SETCAR in
4229 Mon Jan 3 08:25:19 2000 Greg J. Badros <gjb@cs.washington.edu>
4231 * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
4232 SCM_NIMP tests that were redundant are now eliminated. Patches
4233 from Dirk Hermann applied by hand.
