246 This patch unifies the formerly distinct ssymbol and msymbol types
247 to a common symbol type scm_tc7_symbol. The representation of the
248 new symbol type uses a double cell with the following layout:
249 <type/length, chars, raw_hash, prop-pair>, where the car of
250 prop-pair holds the symbol's function property and the cdr of
251 prop-pair holds the symbol's other properties. In the long run,
252 these properties will be removed. Then, the generic property
253 functions will be uses.
255 * eval.c (SCM_CEVAL), objects.c (scm_class_of), print.c
256 (scm_iprin1), tag.c (scm_tag): Use scm_tc7_symbol instead of
257 scm_tc7_ssymbol, scm_tc7_msymbol or scm_tcs_symbols.

261 (scm_gc_sweep): There are no symbol slots any more.

264 of a symbol, use the raw_hash value stored in the symbol itself.
266 * properties.h: Fix typo.
268 * strings.[ch] (scm_makstr, scm_makfromstr): The slot parameter
269 is not used any more.
271 * symbols.[ch] (scm_strhash): Deprecated, replaced by a macro.
273 (scm_intern_obarray_soft): Made softness parameter unsigned.
275 (scm_string_hash): New function with the same functionality as
276 scm_strhash had before, except that the hash value is not adjusted
277 to a hash table size. Instead, the 'raw' hash value is returned.
279 * symbols.c (duplicate_string): New static convenience function.
281 (scm_sym2vcell, scm_sym2ovcell_soft, scm_intern_obarray_soft):
282 Renamed local variable from scm_hash to hash.
284 (scm_intern_obarray_soft): Don't check for a negative softness
285 any more. When generating symbol cells, use the new layout and
286 store the raw hash value in the symbol's cell.
288 (scm_symbol_to_string): Removed unnecessary cast.
290 (scm_intern_symbol, scm_unintern_symbol): Use scm_string_hash to
291 determine the hash values.
293 (msymbolize): Removed.
295 (scm_symbol_fref, scm_symbol_pref, scm_symbol_fset_x,
296 scm_symbol_pset_x, scm_symbol_hash): No need to distinguish
297 between different symbol types any more.
299 (scm_symbol_hash): Comment fixed.
301 * symbols.h: Comment about the distinction between ssymbols and
304 (SCM_SYMBOLP, SCM_ROSTRINGP): No need to distinguish between
305 different symbol types any more.
307 (SCM_PROP_SLOTS, SCM_SET_PROP_SLOTS): Added.
309 (SCM_SYMBOL_FUNC, SCM_SET_SYMBOL_FUNC, SCM_SYMBOL_PROPS,
310 SCM_SET_SYMBOL_PROPS, SCM_SYMBOL_HASH, SCM_SET_SYMBOL_HASH): Use
311 the new symbol cell layout.
313 * tags.h (scm_tc7_ssymbol, scm_tc7_msymbol, scm_tcs_symbols):
316 2000-09-12 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
318 * symbols.h (scm_gentemp): Declared.
320 * symbols.c (scm_gensym): Reimplemented. Now only takes one
321 optional argument which should be a *string*.
322 (scm_gentemp): Reimplemented and moved from boot-9.scm.
324 2000-09-10 Keisuke Nishida <kxn30@po.cwru.edu>

343 * Makefile.am (.x.doc): Bugfix: Added $(srcdir) to path in order
344 to allow for builds in separate tree.

387 2000-09-03 Marius Vollmer <mvo@zagadka.ping.de>
389 * Makefile.am (.x.doc): Pretend to create .doc files from .x files
390 and give explicit dependencies for .x files that depend on
391 generated files. This allows parallel builds. Thanks to Matthias
394 2000-08-27 Marius Vollmer <mvo@zagadka.ping.de>
396 * Makefile.am: Added gc_os_dep.c, properties.c, properties.x,
397 properties.h and properties.doc in the suitable places.
399 * init.h (scm_init_guile): New prototype.
401 * init.c (scm_init_guile, scm_init_guile_1): New interface for
402 initializing Guile that does return to the caller.
403 (scm_boot_guile_1): Use scm_init_guile_1 to initialize Guile.
404 Do not establish a catch-all, this is no longer needed.
406 * root.h (scm_properties_whash): New `sys_protect', used in
409 * throw.c (scm_ithrow): Perform catch-all handling here when no
410 suitable handler has been found. That way, we don't have to rely

412 him if he is using scm_init_guile instead of scm_boot_guile.
414 2000-09-03 Neil Jerram <neil@ossau.uklinux.net>
416 * vectors.c (scm_vector): Docstring: add @deffnx line for

425 incomplete Texinfo reference to a node in r4rs.texi.
426 (scm_symbol_to_string): Escape double quotes correctly within
429 * struct.c (scm_make_struct, scm_make_vtable_vtable): Docstring
430 fixes: `@dots' changed to `@dots{}'.

457 2000-09-03 Michael Livshin <mlivshin@bigfoot.com>
459 the following changes let Guile get rid of the `allocated' cell
462 * smob.c (scm_smob_prehistory): don't init the "allocated" smob
465 * tags.h (scm_tc16_allocated): removed.
467 * gc.h: removed now-obsolete comments about the `allocated' cell

475 (scm_debug_newcell2): ditto.
476 (scm_gc_for_newcell): ditto.

483 * objects.c (scm_init_objects), print.c (scm_init_print), struct.c
484 (scm_init_struct): First arg to scm_make_vtable_vtable should be a
485 string, not a symbol. (`make-vtable-vtable' needs to append this
486 string to another string and then pass it through
487 `make-struct-layout'.)
489 * stacks.c (scm_init_stacks): Pass a string, not a layout object,
490 to scm_make_vtable_vtable. (Thanks to Dale P. Smith.)

493 "read-only string" in comment; Check that argument is a string.
494 (scm_make_vtable_vtable): Check that argument is a string.
496 * environments.c (scm_init_environments): All internal includes in
497 libguile must use the prefix "libguile/" in path names since inly
498 the top-level source directory is on the include list. (That, in
499 turn, is because we want to distinguish between system header
500 files and hedares files internal to libguile.)
502 * strings.c (scm_make_shared_substring, scm_read_only_string_p):
504 (scm_string_length, scm_string_ref, scm_substring,
505 scm_string_append): Don't accept symbols as arguments (R5RS).
507 2000-08-25 Neil Jerram <neil@ossau.uklinux.net>
509 * ports.c (scm_set_port_column_x): Fix docstring so that it
510 mentions set-port-line! rather than set-port-column! twice.
512 * guardians.c (scm_make_guardian): Remove spurious . from doc string.
514 2000-08-25 Dirk Herrmann <D.Herrmann@tu-bs.de>

533 (scm_set_smob_apply): New function.
534 (scm_smob_apply_0, scm_smob_apply_1, scm_smob_apply_2,
535 scm_smob_apply_3): New functions.
536 * eval.c (SCM_CEVAL, SCM_APPLY): Added dispatch for applicable smobs.
537 * procs.c (scm_procedure_p): Check applicable smobs.
539 2000-08-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
541 * Makefile.am (BUILT_SOURCES): Experimentally added scmconfig.h
542 also here. (This is supposed to make sure that scmconfig.h is
543 built before all sources in order to prevent that everything has
544 to be rebuilt again. Hope it works---I'm just guessing. :)
546 * fluids.c (scm_fluid_set_x): Return SCM_UNSPECIFIED.
548 2000-08-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
550 * gc.c (scm_gc_mark): Don't use GUILE_DEBUG flag to compile in
551 extra tests. (GUILE_DEBUG is only supposed to make extra
552 debugging functions available.)

561 * gc.c (scm_gc_sweep): added a `continue' statement that have
562 fallen through the cracks in the merge. thanks to Shuji Narazaki!

565 wasn't actually needed anyway.
567 2000-08-18 Neil Jerram <neil@ossau.uklinux.net>
569 * filesys.c (scm_fcntl): Docstring fix - missing newlines inserted.

587 texinfo markup and remove trailing newlines.
589 2000-08-17 Michael Livshin <mlivshin@bigfoot.com>
591 this changes the Guile GC to use cards (aka "chunklets").
592 (most of the ideas and some of the code are by Greg Harvey, though
593 the code is probably unrecognizable now. the original chunklet
594 proposal, way back, is by Dale Jordan).
596 * tags.h: (SCM_GCTYPE16, SCM_GCCDR, SCM_GC[8]MARKP,
597 SCM_SETGC[8]MARK, SCM_CLRGC[8]MARK): moved from here into gc.h.
598 some (most) of these are probably going to be deprecated.
600 * gc.h (SCM_MARKEDP): simplified, there are no different mark bit
602 (SCM_GC_CARD_*, SCM_C_BVEC_*): lots of new macros to deal with
603 cards and bvecs (bit-vectors).
605 * gc.c: (scm_default_init_heap_size_*): defined to take cards into
606 account, but keeping more or less the same values as previously.
607 added some simple helper macros.
608 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK): defined to take cards
610 (BVEC_*, scm_mark_space_t, current_mark_space, mark_space_ptr,
611 current_mark_space_offset, mark_space_head, get_bvec,
612 clear_mark_space): new functions and supporting variables, types
613 and macros that implement mark space management.
614 (scm_igc): clear the mark space (all of it) before beginning the
616 (scm_gc_mark): changed the tests for rogue cells, much simplified
617 throughout (no different mark bit locations to worry about now).
618 (scm_mark_locations): don't consider card header cells.
620 (scm_gc_sweep): simplified.
621 (init_heap_seg): changed to take cards into account.
623 2000-08-16 Michael Livshin <mlivshin@bigfoot.com>
625 * stime.c (scm_c_get_internal_run_time): new function, same as
626 scm_get_internal_run_time but returns a long. it's used by the GC
627 for timekeeping, since with scm_get_internal_run_time there is a
628 (extremely theoretical) possibility of consing.
629 (scm_get_internal_run_time): redefined in terms of
630 scm_c_get_internal_run_time.
632 * stime.h: added prototype for scm_c_get_internal_run_time.
634 * gc.c (scm_gc_stats): add more obscure stats, such as: mark time,
635 sweep time, total marked cells, total swept cells, and number of
636 times GC was invoked.
637 (gc_start_stats): renamed from scm_gc_start, made static, taught
638 to init the new stats.
639 (gc_end_stats): renamed from scm_gc_end, made static, taught to
640 calculate the new stats.
641 (scm_igc): don't call gc_start_stats unless we are sure that we
642 are indeed going to collect. also, added some timekeeping between
643 the mark and sweep phases.
644 (scm_gc_sweep): count number of cells we sweep as we go.
646 * gc.h: removed prototypes for scm_gc_{start,end}.
648 2000-08-13 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
650 * alist.c (scm_assq, scm_assv, scm_assoc): Report argument type
651 error for the alist rather than the sublist where the type
652 mismatch is discovered.
654 2000-08-13 Neil Jerram <neil@ossau.uklinux.net>
656 * root.c (s_scm_call_with_dynamic_root): Docstring fix - rogue

683 reference manual doc on keywords.
685 * error.c (scm_error_scm): Fix texinfo syntax error in
686 docstring. (@code(~S) should be @code{~S}.)
688 * dynl.c: Remove surplus newlines from end of docstrings.
690 2000-08-11 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
692 * eval.c (scm_eval): Backward incompatible change: Now takes an
693 environment specifier as second arg. `eval' hereby becomes R5RS
695 (scm_i_eval_x, scm_i_eval): New functions (replace
697 (scm_eval2, scm_eval_3): Deprecated.
698 (scm_top_level_lookup_closure_var): Deprecated.

721 scm_interaction_environment ().
723 * script.c (scm_shell): Pass scm_the_root_module () as second arg
726 * load.c (load): Use `scm_selected_module' to compute second arg
727 to new scm_i_eval_x; Don't call it if module system hasn't booted.
728 (scm_read_and_eval_x): Deprecated.
729 #include "modules.h".
731 * debug.c (scm_local_eval): Use scm_i_eval and scm_i_eval_x.
732 (scm_start_stack): Use scm_i_eval.
734 * strports.c: #include "modules.h".
736 * print.c (scm_simple_format): Be case-insensitive for ~A and ~S
739 2000-08-09 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
741 The following changes are intended to ensure that struct instances
742 are freed before their vtables. It's optimized for the most
743 common case, which is freeing of struct instances.
745 * gc.c (scm_gc_mark, scm_gc_sweep): Remove vcell = 1 magic.
746 (scm_structs_to_free): New variable.
747 (scm_gc_sweep): Hook up structs to free on the scm_structs_to_free
750 * struct.h (SCM_STRUCT_GC_CHAIN, SCM_SET_STRUCT_GC_CHAIN): New
752 (scm_structs_to_free, scm_struct_prehistory): Declare.
754 * struct.c (scm_make_struct, scm_make_vtable_vtable): Structs
755 handles are now double cells; Initialize SCM_STRUCT_GC_CHAIN to
757 (scm_struct_gc_init, scm_free_structs): New GC C hooks.
758 (scm_struct_prehistory): Install them.
760 * init.c (scm_boot_guile_1): Call scm_struct_prehistory.
762 2000-08-06 Marius Vollmer <mvo@zagadka.ping.de>
764 * read.c (scm_flush_ws): Include filename in error message when it
767 2000-08-05 Marius Vollmer <mvo@zagadka.ping.de>
769 * iselect.c: Include <unistd.h>. Thanks to Bertrand Petit!
771 2000-08-02 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
773 * struct.c (scm_make_struct_layout, scm_make_struct,
774 scm_make_vtable_vtable): Updated documentation.
776 * print.c (scm_simple_format): Bugfix: Coerce port before using
779 2000-07-31 Gary Houston <ghouston@arglist.com>
781 * net_db.c: declare h_errno only if HAVE_H_ERRNO is not defined
782 (thanks to Richard Kim for the bug report).
784 2000-07-30 Marius Vollmer <mvo@zagadka.ping.de>
786 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
787 scm_assoc_remove_x): Use scm_delq1_x instead of scm_delq_x, since
788 using the latter is pointless.
790 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
792 * gc.c (scm_gc_sweep): Renamed local variable from 'free' to
793 'free_struct_data' to avoid confusion with stdlib's 'free'.
795 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
797 * vectors.c (scm_make_vector): Fix the initialization order of
798 the vector such that the type cell is initialized last.
800 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
802 * struct.[ch] (scm_struct_init): Made static. Fixed not to rely
803 on the struct cell to be fully initialized.
805 * struct.c (scm_make_struct, scm_make_vtable_vtable): Fix the
806 initialization order of the struct such that the type cell is
809 2000-07-25 Marius Vollmer <mvo@zagadka.ping.de>
811 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
812 scm_assoc_remove_x): Remove only the first cell with a matching
815 2000-07-24 Marius Vollmer <mvo@zagadka.ping.de>
817 * stime.c (scm_strftime): Recognize a return value of zero from
818 strftime as buffer overflow and take care to detect a valid zero
819 length result regardless. Thanks to David Barts!
821 2000-07-23 Marius Vollmer <mvo@zagadka.ping.de>
823 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
824 scm_assoc_remove_x): Remove all cells whose key is eq, eqv, or
825 equal (respectively) to the argument key, not all cells that are
826 eq, eqv, or equal to the first cell with the argument key. Thanks
829 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
831 * gc.h (SCM_FREE_CELL_CDR, SCM_SET_FREE_CELL_CDR), hooks.c
832 (make_hook), modules.c (OBARRAY, USES, BINDER): Pack and unpack
833 SCM values appropriately.
835 * modules.c (scm_standard_eval_closure): Don't pass an inum to
836 scm_makcclo, but rather a long value.
838 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
840 read.c (scm_lreadrecparen), srcprop.c (scm_set_source_property_x):
841 SCM_SETCDR and SCM_WHASHSET macros don't deliver a return value.
842 Thanks to Han-Wen Nienhuys for the bug report.
844 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
846 * root.[ch] (scm_call_catching_errors): Deprecated.
848 * root.c (scm_init_root): Initialize the root smob type using the
849 standard initialization functions.
851 2000-07-17 Marius Vollmer <mvo@zagadka.ping.de>
853 * eval.c (unmemocopy): Don't rely on V being a list of at least
854 one element. Thanks to Bill Schottstaedt!
856 2000-07-15 Michael Livshin <mlivshin@bigfoot.com>
858 * gc.c (scm_done_free): new.
859 expanded comments about scm_done_malloc.
861 * gc.h: added prototype for scm_done_free
863 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
865 * gc.h (scm_take_stdin): Removed.
867 * gc.h (SCM_VALIDATE_CELL): Delegate cell checks to function
868 scm_assert_cell_valid to allow extensions to the checking
869 functionality without need to recompile everything.
871 * gc.[ch] (scm_assert_cell_valid, scm_set_debug_cell_accesses_x):
872 Added as conditionally compiled functions for the case that
873 SCM_DEBUG_CELL_ACCESSES is enabled.
875 * gc.c (debug_cells_p): Added to indicate whether compile-time
876 included cell access debugging is run-time enabled.
878 * gc.[ch] (scm_gc_running_p): Added to indicate that scm_igc is
879 being executed. Intended to be used instead of scm_gc_heap_lock
882 * error.c (scm_error), gdbint.c (SCM_GC_P): Use scm_gc_running_p
883 instead of scm_gc_heap_lock.
885 * gc.c (scm_igc): Set scm_gc_running_p to true while running.
887 * gc.c (scm_mark_locations): Don't mark free cells.
889 * weaks.c (scm_scan_weak_vectors): Use SCM_FREE_CELL_P instead of
892 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
894 * gc.c (scm_mark_locations): Minimized some variable scopes and
895 simplified the code a bit.
897 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
899 * gc.h (SCM_SET_FREE_CELL_TYPE, SCM_SET_FREE_CELL_CDR,
900 SCM_FREE_CELL_P, SCM_FREE_CELL_CDR): Added since free cells
901 should not be accessed via SCM_C[AD]R. Further, using dedicated
902 macros to access free cells allows all other cell accessing macros
903 to treat acesses to free cells as errors, thus enabling better
904 error checks for cell accesses. SCM_FREE_CELL_P is supposed to
905 replace SCM_FREEP some time.
907 * gc.h (SCM_NEWCELL, SCM_NEWCELL2), gc.c (map_free_list,
908 free_list_length, scm_check_freelist, scm_debug_newcell,
909 scm_debug_newcell2, freelist_length, scm_gc_for_newcell,
910 scm_gc_mark, scm_gc_sweep, init_heap_seg): Only use the dedicated
911 cell accessors when accessing free cells.
913 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
915 * gc.h (SCM_CELL_WORD, SCM_CELL_OBJECT): Treat the referenced
916 object as const in order to make the compiler warn about code like
917 SCM_CELL_WORD (x, n) = y. Instead, SCM_SET_CELL_WORD (x, n, y)
920 (SCM_CELL_WORD_LOC, SCM_CARLOC, SCM_CDRLOC): Return the address
921 as an address to a non-const object, since these macros are used
922 to allow direct write access to objects.
924 2000-07-07 Dirk Herrmann <D.Herrmann@tu-bs.de>
926 * hashtab.c (scm_hash_fn_create_handle_x): Signal an error if the
927 given hash table has no slots.
929 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
931 * gc.c (policy_on_error): Added in order to allow alloc_some_heap
932 to react to malloc failures in a context dependent way.
934 (scm_check_freelist): No need to flush streams before abort().
936 (scm_gc_for_newcell): Try to allocate new memory in three phases:
937 grow heap if preferred, if still no memory available collect
938 garbage, if still no memory available grow heap.
940 (heap_segment_table_size): Added to always reflect the actual
941 size of the heap segment table, because scm_n_heap_segs may differ
942 from the heap segment table size.
944 (alloc_some_heap): In case of malloc failure, react according to
945 the new policy_on_error parameter (either return to caller or
946 abort immediately). Further, keep heap_segment_table_size up to
949 (scm_init_storage): Initialize heap_segment_table_size.
951 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
953 * gh.h: Don't include <stdio.h>. Thanks to Han-Wen Nienhuys for
956 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
958 * __scm.h (SCM_OUTOFRANGE, SCM_NALLOC, SCM_HUP_SIGNAL,
959 SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL,
960 SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL, SCM_SIG_ORD,
961 SCM_ORD_SIG, SCM_NUM_SIGS): Re-introduce these as deprecated
964 * error.c (scm_wta): Re-introduce dispatching for SCM_OUTOFRANGE
965 and SCM_NALLOC, but as a deprecated feature.
967 2000-06-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
969 * debug.c: Added #include fluids.h.
971 * numbers.c (scm_gr_p, scm_leq_p, scm_geq_p): Turned into
972 primitive generics. (Thanks to Nicolas Neuss.)
974 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
976 * gc.c (alloc_some_heap): Use scm_memory_error to indicate a
977 failed attempt to get additional memory from the system.
979 (scm_gc_for_newcell): Changed the control structure to make the
980 behaviour explicit for the case that gc is not able to free any
983 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
985 * __scm.h (SCM_OUTOFRANGE): Removed.
987 * error.c (scm_wta): Removed sick dispatch code for range
988 errors. (More sick dispatches still to be removed.)
990 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
991 scm_hash_fn_remove_x): Eliminate redundant test for if unsigned
992 value is non-negative. Use scm_out_of_range to signal range
995 * hooks.c (make_hook), unif.c (scm_aind): Use scm_out_of_range to
998 * list.c (scm_list_ref, scm_list_set_x, scm_list_cdr_set_x): Fix
999 error reporting (now uses original input parameter to report wrong
1000 type argument errors). Use SCM_OUT_OF_RANGE to report range
1001 errors and SCM_WRONG_TYPE_ARG to report type errors.
1003 * strings.c (scm_substring): Make range checks for negative
1004 values explicit (former behaviour relied on an implicit
1005 conversion from signed to unsigned). Don't use SCM_ASSERT for
1008 * unif.c (scm_aind, scm_transpose_array, scm_bit_set_star_x,
1009 scm_bit_count_star): Use scm_out_of_range to signal range
1012 * unif.c (scm_transpose_array, scm_bit_position), vectors.c
1013 (scm_vector_ref, scm_vector_set_x, scm_vector_move_left_x,
1014 scm_vector_move_right_x): Use SCM_ASSERT_RANGE to check ranges.
1016 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1018 * validate.h (SCM_VALIDATE_INUM_MIN_COPY,
1019 SCM_VALIDATE_INUM_MIN_DEF_COPY, SCM_VALIDATE_INUM_RANGE_COPY):
1020 Perform all range checks based on the input value. The former way
1021 of using the value that is assigned to the target variable fails
1022 if the assignment to the target variable itself can change the
1023 value because of type conversion.
1025 (SCM_ASSERT_RANGE): Use scm_out_of_range to signal range errors.
1027 2000-06-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1029 * gc.c (scm_gc_for_newcell): Behave gracefully also if scm_igc
1030 doesn't yield any new cells. In theory this could happen if all
1031 cells allocated with NEWCELL are either in use or conservatively
1032 marked and all cluster spine cells are conservatively marked.
1035 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1037 * __scm.h (SCM_NALLOC): Removed.
1039 * error.c (scm_wta): Removed sick dispatch code for memory
1040 errors. (More sick dispatches still to be removed.)
1042 * numbers.c (scm_mkbig, scm_adjbig), ports.c (scm_make_port_type),
1043 random.c (scm_i_copy_rstate, scm_c_make_rstate), smob.c
1044 (scm_make_smob_type), srcprop.c (scm_make_srcprops), vectors.c
1045 (scm_vector_set_length_x): Now using scm_memory_error to signal
1048 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1050 * __scm.h: Removed some commented code and fixed some comments.
1052 (SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL,
1053 SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL,
1054 SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS): Removed.
1056 * async.c: Removed some commented code.
1058 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1060 * gc.c (scm_gc_mark, scm_gc_sweep, scm_must_malloc,
1061 scm_must_realloc, scm_must_free, alloc_some_heap): Use the
1062 appropriate error signalling function.
1064 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1066 * root.h (scm_first_type): Removed.
1068 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1070 * gc.c (MIN_GC_YIELD): Removed.
1072 2000-06-28 Michael Livshin <mlivshin@bigfoot.com>
1074 * gc.c (scm_gc_for_newcell): don't try to do GC if it's blocked,
1077 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1079 * async.c (scm_gc_async, scm_gc_vcell, scm_sys_gc_async_thunk):
1082 (scm_init_async): Moved initialization for scm_gc_async and
1083 scm_gc_vcell to gc.c. Moved initialization of scm_asyncs here
1086 * async.h (scm_gc_async): Not globally visible any more.
1088 * gc.c (scm_gc_stats): Made callable even from within regions
1089 where gc is blocked.
1091 (scm_gc_end): Eliminate the hardcoding of the marking of the
1092 scm_gc_async from the gc core.
1094 (scm_init_storage): Don't initialize the scm_asyncs list here.
1095 This is now done in asyncs.c.
1097 (scm_gc_vcell): Moved here from async.c.
1099 (gc_async): Renamed from scm_gc_async, moved here from async.c
1102 (gc_async_thunk): Renamed from scm_sys_gc_async_thunk and moved
1105 (mark_gc_async): New hook function for scm_after_gc_c_hook.
1107 (scm_init_gc): Added initialization of scm_gc_vcell and
1108 gc_async. Further, add mark_gc_async to scm_after_gc_c_hook.
1110 * init.c (scm_boot_guile_1): scm_init_gc requires asyncs to be
1113 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1115 * gc.c (scm_igc): Removed commented code that once was intended
1116 to unprotect struct types with no instances.
1118 * root.h (scm_type_obj_list): Removed.
1120 2000-06-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
1122 * async.c (scm_init_async): Switch to standard way of smob
1125 2000-06-21 Michael Livshin <mlivshin@bigfoot.com>
1127 * guile-doc-snarf.in: use cut instead of sed, that's much much
1128 faster. also, don't call basename more than needed. and, to gain
1129 a couple of microseconds more, don't call cat needlessly. (thanks
1132 2000-06-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
1134 * guile-snarf.awk.in, guile-snarf.in, snarf.h: Rename SCM__I to
1135 SCM_SNARF_INIT_START, SCM__D to SCM_SNARF_DOC_START, SCM__S to
1136 SCM_SNARF_DOCSTRING_START and SCM__E to SCM_SNARF_DOCSTRING_END.
1138 2000-06-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1140 * eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
1141 #include "libguile/fluids.h".
1143 * eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
1144 SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
1146 * root.h (scm_top_level_lookup_closure_var,
1147 scm_system_transformer): Removed. (It's no sense in having the
1148 *variable* be a "fluid".)
1150 * root.c (mark_root): Removed marking of
1151 s->top_level_lookup_closure_var and s->system_transformer.
1153 * modules.c (scm_selected_module): the_module is now a fluid.
1155 2000-06-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1157 * gc.h, tags.h: Be kind to compilers which must see hash signs in
1158 column 0. (Thanks to Ian Grant.)
1160 * numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
1161 the long_long type. (Thanks to Bernard Urban.)
1163 2000-06-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1165 * gc.c, gc.h (scm_default_init_heap_size_1,
1166 scm_default_min_yield_1, scm_default_init_heap_size_2,
1167 scm_default_min_yield_2, scm_default_max_segment_size): New global
1168 variables. Can be customized by the application before booting
1169 Guile. (We might want to be able to control these parameters
1170 dynamically through the "options interface" in the future, but
1171 note that that is additional functionality. Here we're giving
1172 default values which the environment variables can override.)
1174 * list.c (scm_cons_star): Updated comment.
1176 * smob.h: Changed comments for scm_make_smob_type and
1177 scm_make_smob_type_mfpe, warning that the latter might be
1178 deprecated in a future release.
1180 2000-06-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1182 * list.[ch] (scm_cons_star/cons*): Renamed from
1183 scm_list_star/list*.
1185 * list.[ch] (scm_list_star/list*): Provided as a deprecated alias
1186 for scm_cons_star/cons*.
1188 * gc.c (scm_protect_object): Updated comment.
1190 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX): Removed.
1192 * tags.h (SCM_UNPACK_CAR, SCM_NDOUBLE_CELLP): Removed.
1194 2000-06-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1196 * init.c, init.h (scm_initialized_p): Renamed from `initialized'
1199 * gdbint.c (gdb_print): Print warning instead of calling scm_write
1200 if Guile isn't yet initialized.
1202 * print.c (scm_current_pstate, scm_make_print_state): Simplified
1203 tests, using the assumption that Guile has been initialized.
1205 Sun Jun 18 14:45:21 2000 Greg J. Badros <gjb@cs.washington.edu>
1207 * print.c (s_scm_current_pstate): Do not segfault when the
1208 print_state_pool is unitialized in `current-pstate', and better
1209 verify its state before altering it in scm_make_print_state().
1211 2000-06-18 Michael Livshin <mlivshin@bigfoot.com>
1213 * scmsigs.c (s_scm_sigaction): guard the SIGIOT case with an
1214 #ifdef -- it's missing on at least one platform. (thanks to
1217 2000-06-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1219 * list.c (list*): Added documentation from common-list.scm.
1221 2000-06-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
1223 * gc.c (scm_unprotect_object): The reference count is guaranteed
1224 to be a positive number.
1226 2000-06-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1228 * eval.c: Updated comment above scm_map.
1230 2000-06-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1232 * gc.c (scm_protect_object): Avoid looking up the object handle
1234 (scm_unprotect_object): Abort if scm_unprotect_object is called on
1235 an unprotected object.
1237 2000-06-14 Michael Livshin <mlivshin@bigfoot.com>
1239 * gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
1242 2000-06-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1244 * socket.c (scm_getsockopt): Changed type for `optlen' from int to
1246 (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
1247 Ditto for `tmp_size'.
1248 (scm_addr_buffer_size): Changed type from int to size_t.
1250 * random.c: #include <string.h>. (Needed by memcpy.)
1252 * guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
1253 indicating stdin, instead of "" and don't reset ARGC. This is a
1254 workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
1255 it is correct, and perhaps even better.
1257 2000-06-14 Gary Houston <ghouston@arglist.com>
1259 * scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not
1260 defined, add SA_RESTART to the sigaction flags correctly
1261 (thanks to Dale P. Smith).
1263 2000-06-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1265 * strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
1267 * net_db.c (scm_resolv_error): Only use macro NETDB_INTERNAL if
1268 defined. It isn't on sgi irix 5.3. (Thanks to Bill Schottstaedt.)
1270 * Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
1272 2000-06-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1274 * fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
1275 since read and write buffers are allocated by `malloc'.
1277 * Makefile.am: Removed old test code.
1279 * gh_test_c.c, gh_test_repl.c: Removed.
1281 2000-06-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1283 * iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2
1286 * inet_aton.c (inet_aton): Cast init value for `cp'.
1288 * ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
1291 * symbols.c (scm_intern_obarray_soft,
1292 scm_sysintern0_no_module_lookup): Cast `name' to unsigned char ptr
1293 in calls to scm_strhash.
1295 * strports.c (st_resize_port): Substituted SCM_UCHARS for
1297 (st_write): Cast argument to strncpy to char ptr.
1298 (scm_mkstrport): Substituted SCM_ROUCHARS for SCM_ROCHARS.
1299 (scm_strport_to_string): Cast argument to scm_makfromstr to char
1302 * ports.c (scm_ungetc): Cast value to unsigned char ptr before
1303 storing in putback_buf.
1304 (scm_unread_string): Substituted SCM_ROCHARS for SCM_ROUCHARS.
1306 * ioext.c (s_scm_read_line): Cast result of call to
1307 scm_do_read_line to unsigned char ptr.
1309 * gdbint.c (SEND_STRING): Cast argument to char pointer.
1311 * fports.c (fport_flush): Declare `ptr' as unsigned char (was
1314 * Makefile.am (DOT_DOC_FILES): List doc-files explicitly. (We
1315 shouldn't use Make rules which aren't supported by most Make
1317 (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h". (We don't
1318 want these dependencies recorded, since they would get bogus
1319 relative paths; libguile.h is only used in gh.h and guile.c.)
1320 (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
1321 (guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
1322 (modinclude_HEADERS): Removed kw.h.
1324 * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
1325 (The preprocessor might insert spaces before the identifier.)
1327 * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
1328 Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
1330 * smob.h (scm_smobfuns): Removed deprecated type.
1332 * smob.c, smob.h (scm_newsmob): Removed deprecated function.
1333 (Replaced by `scm_make_smob_type'.)
1335 * keywords.c (scm_tc16_kw): Removed deprecated type.
1336 (Replaced by scm_tc16_keyword.)
1338 * kw.h: Removed deprecated header file.
1340 * evalext.c (serial-map): Removed deprected alias for scm_map.
1341 (Has been replaced by `map-in-order'.)
1343 * ramap.c (serial-array-copy!, serial-array-map!): Removed
1344 depracted aliases. (Replaced by `array-copy-in-order!' and
1345 `array-map-in-order'.)
1347 2000-06-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1349 * gc.h (SCM_VALIDATE_CELL): Rewritten.
1350 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
1351 SCM_SET_CELL_OBJECT): Use new version of SCM_VALIDATE_CELL.
1352 (Thanks to Han-Wen Nienhuys.)
1354 2000-06-10 Michael Livshin <mlivshin@bigfoot.com>
1356 * guile-doc-snarf.in: don't pipe the CPP output right into sed --
1357 write it to the temp file first and check the CPP return code.
1358 (I introduced this bug earlier, and this probably caused people
1359 with non-GNU C preprocessors to get empty *.x files and not to
1360 have the build fail right away...).
1362 * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
1363 -- at least my libc5-based Linux system doesn't define SIGSYS.
1365 2000-06-08 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1367 * snarf.h, guile-snarf.awk.in, guile-snarf.in: Replaced snarf
1368 markers with identifiers (SCM__I, SCM__D, SCM__S, SCM__E).
1369 (Thanks to Bernard Urban.)
1371 2000-06-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1373 * modules.c (scm_system_module_env_p): Fixed detection of system
1376 2000-06-06 Marius Vollmer <mvo@zagadka.ping.de>
1378 * scmsigs.c (scm_sigaction): Silently ignore setting handlers for
1379 `program error signals' because they can't currently be handled by
1382 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1384 * procs.h (SCM_SET_SUBRF): Added.
1386 * procs.c (scm_make_subr_opt): Don't assign to SCM_SUBRF, use
1387 SCM_SET_SUBRF instead. Thanks to Bernard Urban for the bug
1390 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1392 * gc.h (SCM_CARLOC, SCM_CDRLOC): Don't take the address of a SCM
1395 * sort.c (scm_sorted_p, scm_merge, scm_merge_list_x,
1396 scm_merge_list_step): Don't take the address of SCM_CAR. Use
1397 SCM_CARLOC instead. Thanks to Bernard Urban for the bug report.
1399 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1401 * boolean.h (SCM_TRUE_P): Removed, as people might use it as a
1402 replacement for !SCM_FALSEP.
1404 * backtrace.c (display_error_body), boolean.h (SCM_BOOLP), gc.c
1405 (scm_unhash_name), gh_data.c (gh_module_lookup), load.c
1406 (scm_primitive_load), print.c (scm_simple_format), procs.c
1407 (scm_procedure_documentation), procs.h (SCM_TOP_LEVEL), ramap.c
1408 (scm_array_fill_int), scmsigs.c (scm_sigaction), stacks.c
1409 (narrow_stack, scm_make_stack, scm_stack_id), symbols.c
1410 (scm_string_to_obarray_symbol), throw.c (scm_catch,
1411 scm_lazy_catch, scm_ithrow), unif.c (scm_make_uve, scm_array_p,
1412 scm_array_set_x, scm_bit_set_star_x, scm_bit_count_star),
1413 validate.h (SCM_VALIDATE_BOOL_COPY, SCM_VALIDATE_PROC): Replace
1414 uses of SCM_TRUE_P (x) with SCM_EQ_P (x, SCM_BOOL_T).
1416 2000-06-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1418 * eval.c (scm_badformalsp): New static function.
1419 (SCM_CEVAL): Check arguments for procedure-with-setter closures.
1420 (Thanks to Keisuke Nishida.)
1422 The major reason for Guile's slow loading speed has been the fact
1423 that a chain of Scheme level procedures has been evaluated for
1424 every top-level symbol lookup during the first pass through the
1427 The following is a kludge which I suggested four years ago, and
1428 which I've repeatedly suggested since. Personally, I've never
1429 been bothered by Guile's slow loading speed, so I thought I would
1430 let someone else do it...
1432 But since the new environments will be included first in
1433 Guile-1.5, I thought it would make people happy to get the kludge
1436 * modules.c: Added #include "libguile/vectors.h";
1437 Added #include "libguile/hashtab.h";
1438 Added #include "libguile/struct.h";
1439 Added #include "libguile/variable.h";
1440 Capture Scheme level `module-make-local-var!' to be used in the
1441 standard eval closure.
1442 (scm_standard_eval_closure): New primitive.
1444 * modules.h (scm_standard_eval_closure): Declare.
1446 * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
1447 instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
1449 * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
1450 standard eval closures.
1452 * variable.c: Code layout fixes.
1454 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1456 * Makefile.am: Added LIBS line to libpath which accidentally
1457 disappeared in the change of 2000-06-01.
1458 (Thanks to Dale P. Smith.)
1460 2000-06-03 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1462 * scmsigs.c (scm_segfault): Removed. (Was probably added by
1463 mistake since it is not mentioned in ChangeLog.)
1465 * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
1466 avoid compiler warnings in gcc. (Does this work for other
1469 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1471 * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
1473 (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
1474 SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1. It's not correct to take
1475 the address of these expressions since they use SCM_VALIDATE_CELL.
1476 (Thanks to Bernard Urban.)
1478 * dynl.c: Changed #include <ltdl.h> --> #include
1479 "libltdl/ltdl.h". (Thanks to Bill Schottstaedt.)
1481 2000-06-01 Craig Brozefsky <craig@red-bean.com>
1483 * Makefile.am: libguile_la_LDFLAGS gets -version-info args
1484 from GUILE-VERSION definition of LIBGUILE version. Added to
1485 libpath.h definitions for guileversion and libguileversion which
1486 both get their values from GUILE-VERSION definition.
1488 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1490 * numbers.h (SCM_BIGP): Don't use SCM_SMOB_PREDICATE in header
1491 file: Code using numbers should not be required to include
1494 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1496 * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
1497 mit-pthreads.c, mit-pthreads.h: Deleted.
1499 * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]: Drop
1500 references to deleted files and fsu/mit thread support in
1503 2000-05-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1505 * hooks.c (symbol_name, scm_create_hook): Restored the original
1506 behaviour of scm_create_hook. Changing it was bad as Carl
1507 R. Witty has pointed out.
1509 * gc.c (scm_init_gc): We can still rely on scm_create_hook to
1512 2000-05-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
1514 * gc.c (scm_init_gc): Protect scm_after_gc_hook, since this will
1515 soon not be done by scm_create_hook any longer.
1517 * hooks.c (make_hook, print_hook, scm_create_hook,
1518 scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
1519 SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
1520 scm_make_hook_with_name), init.c (scm_boot_guile_1): Hooks no
1521 longer have names. As an intermediate solution, the name
1522 predicate is emulated via object properties, but use of this
1523 feature is deprecated.
1525 * hooks.h (scm_free_hook): Removed, as it is never defined.
1527 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1529 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
1530 Un-deprecated since otherwise user code can't determine whether a
1531 number fits into an inum any longer. The names should be changed
1534 * numbers.c (scm_big2inum): Eliminated use of SCM_UNEGFIXABLE.
1536 * tags.h (SCM_UNPACK_CAR): Deprecated.
1538 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1540 * filesys.h (SCM_OPDIRP), fluids.h (SCM_FLUIDP, SCM_FLUID_NUM),
1541 fports.h (SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP), hooks.h
1542 (SCM_HOOK_ARITY), keywords.h (SCM_KEYWORDP, SCM_KEYWORDSYM),
1543 numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
1544 Replace SCM_UNPACK_CAR appropriately. Don't access cells via
1545 SCM_{SET}?C[AD]R unless they are known to be cons cells.
1547 * gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
1548 init_heap_seg): Remove unused struct member variable 'valid'.
1550 2000-05-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
1552 * fports.c (fport_write), ports.c (scm_markstream, scm_port_mode,
1553 scm_print_port_mode), ports.h (SCM_OPPORTP, SCM_OPINPORTP,
1554 SCM_OPOUTPORTP, SCM_INPUT_PORT_P, SCM_OUTPUT_PORT_P, SCM_OPENP),
1555 procs.h (SCM_CLOSCAR), unif.h (SCM_ARRAY_NDIM, SCM_ARRAY_CONTP),
1556 variable.h (SCM_VARIABLEP): Replace SCM_UNPACK_CAR
1559 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1561 * gc.c (free_list_length), hash.c (scm_hasher), macros.c
1562 (scm_macro_type), objects.c (scm_class_of), options.c
1563 (scm_options), print.c (scm_iprin1), strports.c (st_seek), throw.c
1564 (SCM_LAZY_CATCH_P): Replace SCM_UNPACK_CAR appropriately.
1566 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1568 * eval.c (scm_macroexp, SCM_CEVAL, scm_force), tags.h: Replace
1569 SCM_UNPACK_CAR with SCM_CELL_TYPE or SCM_CELL_WORD_0.
1571 * eval.c (scm_force): Add documentation.
1573 * eval.c (scm_force, scm_cons_source): Don't access cells via
1574 SCM_{SET}?C[AD]R unless they are known to be cons cells.
1576 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1578 * strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
1579 (SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP): Deprecated.
1581 * gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT): Removed #ifdef
1582 nosve #endif conditionally compiled code.
1584 2000-05-23 Michael Livshin <mlivshin@bigfoot.com>
1586 * gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
1588 2000-05-22 Michael Livshin <mlivshin@bigfoot.com>
1590 * guile-doc-snarf.in: put the preprocessed file through sed to
1591 trim all lines to 1024 chars. I hope it doesn't break anybody's
1592 sed. we'll see. (note: this is lossy trimming, i.e. the spill
1593 isn't wrapped around but actually chopped off. this seemed to me
1594 safe because the current snarfer doesn't understand multi-line
1595 cookies anyway. in the long term, it would be nice not to depend
1596 on AWK for anything.)
1598 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
1599 the previous change to this macros, after deciding to torture the
1602 2000-05-21 Michael Livshin <mlivshin@bigfoot.com>
1604 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
1605 the yucky, ugly and nasty conditional compilation back. sorry,
1606 but it was either that or requiring GAWK to build Guile.
1607 (lots of places): removed the code that implemented the old GC
1610 * init.c (scm_boot_guile_1): removed the code conditioned on
1611 !GUILE_NEW_GC_SCHEME.
1613 * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
1615 * gc.c (scm_protect_object, scm_unprotect_object): change the
1616 implementation to more efficient (at least in the time complexity
1617 sense). the calls should now also be thread-safe -- I suspect
1618 that people expect them to be. (thanks to Han-Wen Nienhuys)
1619 (lots of places): removed the code that implemented the old GC
1622 * hashtab.c (scm_hash_fn_create_handle_x): add missing
1623 SCM_REALLOW_INTS before return. I really wonder about the
1624 possible interactions between hashtables, threads & GC. it
1625 doesn't look healthy at all.
1627 2000-05-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1629 * unif.c (scm_bit_count): Fixed the parameter checks. Thanks to
1632 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1634 * __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_): Added as a new
1635 debug option to verify all accesses to cells actually access
1636 objects on the heap.
1638 * gc.h (SCM_VALIDATE_CELL): Added. Only performs validation if
1639 SCM_DEBUG_CELL_ACCESSES is set to 1.
1641 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
1642 SCM_SET_CELL_OBJECT): Use SCM_VALIDATE_CELL to check every cell
1645 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1647 * gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs,

1650 * gc.c (scm_cellp): Fixed and simplified.
1652 * throw.c (JBJMPBUF, SETJBJMPBUF, SCM_JBDFRAME, SCM_SETJBDFRAME,
1653 make_jmpbuf, scm_init_throw): Now using double cells to represent
1654 jump buffers when using debug extensions.
1658 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1660 * gh.h gh_data.c gh_funcs.c (gh_new_procedure*, gh_chars2byvect,

1662 gh_doubles2dvect, gh_doubles2scm, gh_define, gh_lookup,
1663 gh_module_lookup): Accept const pointers as parameters.
1665 * gh.h gh_data.c (gh_int2scmb): Deprecated.
1667 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1669 * __scm.h (SCM_DEBUG_REST_ARGUMENT): Renamed from
1670 SCM_DEBUG_REST_ARGUMENTS in order to clarify that we don't test
1671 the actual arguments in the list, but rather the rest argument as
1672 a list of arguments.
1674 * validate.h (SCM_VALIDATE_REST_ARGUMENT): Added.
1676 * async.c (scm_noop), eval.c (scm_map, scm_for_each), list.c
1677 (scm_list_star, scm_append, scm_append_x), ports.c
1678 (scm_close_all_ports_except), ramap.c (scm_array_map_x,
1679 scm_array_for_each), regex-posix.c (scm_make_regexp), stacks.c
1680 (scm_make_stack), strings.c (scm_string_append), struct.c
1681 (scm_make_struct, scm_make_vtable_vtable): Validate rest arguments.
1683 * dynl.c (DYNL_GLOBAL, sysdep_dynl_link, kw_global, sym_global,
1684 scm_dynamic_link, scm_init_dynamic_linking), dynl.h
1685 (scm_dynamic_link): Removed possibility to pass flags to
1686 scm_dynamic_link, as it had no effect anyway.
1688 * filesys.c (scm_fcntl): Made single optional rest argument into
1689 a standard optional argument.
1691 * hooks.c (scm_run_hook): A list of rest arguments is never
1694 * list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
1695 strings.c (scm_string_append): Don't perform half-hearted checks
1696 to see whether the rest argument forms a proper list any more, use
1697 SCM_VALIDATE_REST_ARGUMENTS instead.
1699 * ports.c (scm_close_all_ports_except): Accept empty list of rest
1702 * posix.c (scm_convert_exec_args), print.c (scm_simple_format):
1703 Simplify verification of rest argument.
1705 * stacks.c (scm_make_stack), stacks.h (scm_make_stack), throw.c
1706 (ss_handler, handler_message): Make first mandatory rest argument
1707 of scm_make_stack into a standard mandatory argument.

1710 scm_array_in_bounds_p), unif.h (scm_transpose_array,
1711 scm_enclose_array, scm_array_in_bounds_p): Make first mandatory
1712 rest argument into a standard mandatory argument.
1714 2000-05-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
1716 * __scm.h: Added SCM_DEBUG as default debug option. (Thanks to
1717 Keisuke Nishida for the suggestion.) Added debug option
1718 SCM_DEBUG_REST_ARGUMENTS.
1720 * eval.c (scm_map, scm_for_each): Make sure all lists have the
1721 same length. Also, removed redundant parameter checks.
1723 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1725 * Makefile.am: Let 'make clean' remove *.x and *.doc files.
1727 * __scm.h: Improved explanation of giving options to make.
1729 * __scm.h (SCM_DEBUG_TYPING_STRICTNESS), tags.h
1730 (SCM_STRICT_TYPING, SCM_DEBUG_TYPING_STRICTNESS): Renamed
1731 SCM_STRICT_TYPING to SCM_DEBUG_TYPING_STRICTNESS and moved the
1732 corresponding declaration and comment to __scm.h.
1734 * _scm.h (errno), gc.h (SCM_CELLPTR, SCM_PTR_LT), numbers.c
1735 (scm_remainder, scm_modulo), numbers.h (SCM_SRS, SCM_MAKINUM,
1736 SCM_INUM): Removed conditionally compiled code for Turbo C.
1738 * gdbint.c (gdb_maybe_valid_type_p): Eliminated call to scm_tag.
1739 That check can be assumed to be redundant except for very rare
1740 conditions that actually indicate broken heap data.
1742 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1744 * numbers.c (scm_logcount, scm_integer_length): Reordered
1747 2000-05-15 Gary Houston <ghouston@arglist.com>
1749 * stime.c (scm_strftime): don't reset TZ if zone is an empty
1750 string. append a "0" to the zone for TZ.
1752 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
1754 * numbers.c (scm_logbit_p, scm_bit_extract): Reordered dispatch
1757 (scm_bit_extract): Fixed handling of bignums.
1759 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
1761 * async.c (scm_sys_gc_async_thunk), chars.h (SCM_ICHRP, SCM_ICHR,
1762 SCM_MAKICHR), continuations.h (SCM_SETJMPBUF), error.c

1766 SCM_INPORTP, SCM_OUTPORTP), ramap.c ('serial-array-copy!,
1767 'serial-array-map!), smob.c (scm_newsmob), smob.h (scm_smobfuns,
1768 scm_newsmob), tag.c (scm_tag), tag.h (scm_tag), tags.h
1769 (scm_tc16_flo, scm_tc_flo, scm_tc_dblr, scm_tc_dblc): Wrapped
1770 deprecated code between #if (SCM_DEBUG_DEPRECATED == 0) #endif.
1772 * fports.c (scm_fport_buffer_add), ports.c (scm_input_port_p,
1773 scm_output_port_p), print.c (scm_get_print_state), validate.h
1774 (SCM_VALIDATE_CHAR): Replace use of deprecated macros
1775 SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
1776 SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
1778 2000-05-14 Gary Houston <ghouston@arglist.com>
1780 * stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
1781 TZ environment variable so that the %Z format returns the zone
1782 from the input vector instead of the system default.
1784 from Keisuke Nishida:
1785 * fports.c (scm_setvbuf): minor docstring fix.
1786 * ports.h (scm_generic_fgets): obsolete prototype deleted.
1788 2000-05-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
1790 * __scm.h: Added new section for debugging options.
1792 (SCM_DEBUG_DEPRECATED): If 1, no deprecated code is included to
1793 help developers to get rid of references to deprecated code.
1795 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,
1796 SCM_FIXABLE, SCM_FLOBUFLEN): These macros are no longer provided
1797 as part of the interface and are marked as deprecated in the
1800 * numbers.c (scm_make_real, scm_make_complex): Inlined the
1801 corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
1804 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,
1805 SCM_REAL, SCM_IMAG, SCM_REALPART, scm_makdbl, SCM_SINGP,
1806 SCM_NO_BIGDIG, SCM_NUM2DBL, scm_dblproc): Deprecated.
1808 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1810 * gc.h (scm_cell, SCM_CELL_WORD, SCM_CELL_OBJECT,
1811 SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT): Scheme cells now consist
1812 of two scm_bits_t values instead of two SCM values, because it is
1813 legal for cell entries to hold values that are not scheme objects.
1815 (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
1816 Use SCM_SETC[AD]R to modify contents of pairs.
1818 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1820 * numbers.c (IS_INF, isfinite): Added FIXME comment.
1822 (scm_abs, scm_magnitude): Make these two independent of each
1823 other. scm_abs now reports an error if given a complex argument.
1825 (scm_istr2flo, scm_integer_p). Use SCM_REAL_VALUE instead of
1826 SCM_REALPART if the object is known to be real.
1828 (scm_init_numbers): No need to use SCM_NEWREAL macro for speed
1831 * numbers.h (SCM_SINGP): Set to 0 instead of SCM_BOOL_F.
1833 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1835 * eq.c (scm_eqv_p): Separate handling of real and complex
1836 values. Remove #ifdef SCM_BIGDIG #endif test.
1838 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_scm2floats,
1839 gh_scm2doubles), hash.c (scm_hasher), ramap.c (scm_array_fill_int,
1840 ramap_rp, scm_array_map_x), random.c (vector_scale,
1841 vector_sum_squares), unif.c (scm_make_uve, scm_array_p,
1842 scm_array_set_x): Use SCM_REAL_VALUE instead of SCM_REALPART if
1843 the object is known to be real. Use SCM_COMPLEXP instead of
1844 deprecated SCM_CPLXP. Use SCM_INEXACTP instead of deprecated
1847 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1849 * numbers.c: No need to include unif.h.
1851 (IS_INF): Returned to old test for now: x == x + 1 will not work
1852 for large numbers due to rounding errors.
1853 Thanks to Kalle Olavi Niemitalo.
1855 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1857 * numbers.c (scm_divbigdig): Removed outdated comment.
1859 (scm_number_to_string, scm_string_to_number, scm_number_p,
1860 scm_real_p, scm_integer_p, scm_inexact_p, scm_gr_p, scm_leq_p,
1861 scm_geq_p, scm_make_rectangular, scm_make_polar,
1862 scm_inexact_to_exact): Added comments.
1864 (add1, scm_init_numbers): Removed add1.
1866 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1868 * numbers.c (IS_INF): The new test is x == x + 1. The old test
1869 x == x/2 did not work for zero values. Thanks to Han-Wen Nienhuys
1872 (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
1873 scm_num2long, scm_num2long_long, scm_num2ulong): Reordered
1876 2000-05-09 Marius Vollmer <mvo@zagadka.ping.de>
1878 * scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
1879 SIGILL and SIGBUS signals. These signals are not continuable and
1880 must be handled for real right away.
1882 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1884 * numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,
1885 scm_real_part, scm_imag_part, scm_magnitude,
1886 scm_inexact_to_exact): Reordered dispatch sequence.
1888 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1890 * feature.c: No need to include "libguile/smob.h"
1892 (scm_loc_features, features, scm_add_feature, scm_init_feature):
1893 Removed variable 'scm_loc_features' as a pointer to the SCM value
1894 holding the features list. Using variable 'features' instead,
1895 which holds the interned pair. Thus, SCM_SETCDR can be used
1896 instead of pointer trickery.
1898 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1900 * alist.c (scm_acons): Use SCM{_SET}?_CELL_OBJECT as long as a
1901 cell is not known to be a valid pair.
1903 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1905 * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1): Removed
1906 ASRTSYNTAX. Using SCM_ASSYNT instead.
1908 (scm_m_body): Don't create a redundant cons cell.
1910 (scm_m_do): Removed redundant test 'bodycheck'.
1912 (bodycheck): Removed.
1914 * stacks.c (stack_depth, read_frame, read_frames): Removed
1915 redundant calculation of size, minimized some variable scopes.
1917 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1919 * pairs.c (scm_cons, scm_cons2): Use SCM{_SET}?_CELL_OBJECT as
1920 long as a cell is not known to be a valid pair.
1922 (scm_pair_p): Eliminated redundant SCM_IMP test.
1924 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1926 * eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,
1927 scm_deval_args): Eliminated redundant SCM_IMP tests.
1929 * hashtab.c (scm_ihashx, scm_sloppy_assx, scm_delx_x), weaks.c
1930 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
1931 scm_make_doubly_weak_hash_table): Fixed critical sections.
1932 Thanks to Keisuke Nishida.
1934 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1936 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
1937 Fixed some goto-related initialization bugs (introduced by me).
1939 2000-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
1941 * numbers.h (SCM_INUM0): Uses SCM_MAKINUM instead of SCM_PACK.
1943 * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj): Removed.
1945 (DYNL_FILENAME, DYNL_HANDLE): Use SCM_CELL... macros instead of
1948 (SET_DYNL_HANDLE): Added.
1950 (scm_dynamic_object_p): Simplified.
1952 (scm_dynamic_unlink, scm_dynamic_func): Changed comment. Deliver
1953 better error message when accessing unlinked dynamic objects.
1954 Eliminated call to get_dynl_obj.
1956 2000-05-03 Marius Vollmer <mvo@zagadka.ping.de>
1958 * scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
1959 be an array of function pointers instead of being a pointer to an
1960 array returning function. Thanks to Kalle Olavi Niemitalo!
1962 2000-05-03 Dirk Herrmann <D.Herrmann@tu-bs.de>
1964 * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
1965 (scm_divbigbig, scm_divbigint): Don't return zero any more to
1966 indicate that a division has a remainder, return SCM_UNDEFINED
1967 instead. It is improbable that anyone actually used these
1968 functions outside of numbers.c. For this reason and due to the
1969 change in behaviour the functions are static now. Thus, if
1970 surprisingly there are users of these functions they will at least
1973 * numbers.c: Removed #ifdef SCM_BIGDIG #endif in those functions,
1974 that already have a clean dispatch order. Note: SCM_BIGDIG is
1977 * numbers.c (scm_inexact_p): Simplified.
1979 * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
1980 scm_product, scm_num2dbl, scm_angle): Reordered dispatch
1981 sequence, thereby fixing some comparisons of SCM values with
1984 * numbers.c (scm_divide): Division by zero of inums leads to an
1985 error now. (Formerly, an infinite number was returned.)
1987 Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
1988 if a division has a remainder.
1990 2000-05-02 Gary Houston <ghouston@arglist.com>
1992 * Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).
1994 2000-05-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
1996 * numbers.c (scm_logtest, scm_division): Reordered dispatch
1997 sequence, thereby fixing some comparisons of SCM values with
2000 * numbers.h (scm_makdbl): Mark as deprecated at the point of
2003 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_double2scm,
2004 gh_doubles2scm), numbers.c (scm_istr2flo, scm_max, scm_min,

2010 scm_random_uniform, scm_random_normal_vector_x, scm_random_exp),
2011 struct.c (scm_struct_ref), unif.c (scm_array_to_list): Replace
2012 call to scm_makdbl with a call to scm_make_real or
2013 scm_make_complex, depending on whether the imaginary part is known
2016 2000-05-01 Gary Houston <ghouston@arglist.com>
2018 * scmsigs.c: fix the definition of orig_handlers for the case
2019 that HAVE_SIGACTION is not defined (thanks to
2020 Kalle Olavi Niemitalo).
2022 * Makefile.am: remove include_HEADERS (was libguile.h)
2023 libguile.h: moved to top level directory.
2025 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2027 * numbers.c (SCM_SWAP): Moved to the top of the file to allow for
2030 * numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,

2032 comparisons of SCM values with integer constants.
2034 * number.c (scm_logtest): Removed some redundant SCM_{N}?IMP
2037 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2039 * numbers.c (scm_quotient, scm_remainder): Removed code that was
2040 conditionally compiled based on BADIVSGNS. BADIVSGNS does not
2041 occur anywhere else throughout guile.
2043 * numbers.c (scm_quotient): Fixed parameter number in error
2046 * numbers.c (scm_remainder): Reordered dispatch sequence.
2048 2000-04-25 Gary Houston <ghouston@arglist.com>

2056 (suggested by Jost Boekemeier).
2058 2000-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2060 * pairs.c (cxrs, scm_init_pairs): Simplify initialization of
2063 * procs.c (scm_init_iprocs), procs.h (scm_subr, scm_iproc,
2064 scm_dsubr, scm_init_iprocs): Removed.
2066 * procs.h (SCM_SUBRF, SCM_DSUBRF): Access the cell words
2067 directly instead of casting a cell to a C struct.
2069 2000-04-22 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2071 Better modularization of GC extensions through new C level GC
2074 * weaks.c (scm_weaks_prehistory): New function: Add

2083 * guardians.h (scm_guardian_gc_init, scm_guardian_zombify): Are
2086 * guardians.c (scm_guardian_gc_init): Turned into a hook function
2087 and added to scm_before_mark_c_hook.
2088 (scm_guardian_zombify): Turned into a hook function and added to
2089 scm_before_sweep_c_hook.

2128 Removed all -I options except for the root source directory and
2129 the root build directory.
2131 * numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG
2132 instead of SCM_ASSERT (0, ...). (Some compilers will complain

2155 functions respectively signal wrong type arguments. Hopefully
2156 this will allow for easier separation when goops is integrated.
2158 2000-04-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
2160 * gc.c (which_seg): Use SCM2PTR to convert a non immediate SCM

2440 * validate.h: move async validation macros to async.c (nobody else
2441 needs them anyway), and rename them.
2443 2000-04-04 Michael Livshin <mlivshin@bigfoot.com>
2445 * async.h: kill the scm_async_t struct. having a heap cell
2446 pretending to be a C struct is not helthy, and is not needed here
2447 anyway, as asyncs happily fit in one heap cell.

2517 separate loop after processing all the currently known live
2518 guardians, so as to not introduce order dependencies (thanks to
2519 Gary Houston). note that the order problems are still there if
2520 some guardians are themselves zombies, but that's a sick case that
2521 I'm not going to worry about.
2522 also, make another outer loop to process zombified
2523 guardians (which are uncovered while marking zombies).

2603 SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): Don't initialize globals
2604 and static variables at their point of declaration, but rather in
2607 * tags.h (SCM_PACK): Automatically cast to scm_bits_t.
2609 2000-04-02 Gary Houston <ghouston@arglist.com>
2611 * guardians.c (TCONC_IN, scm_make_guardian): set the CDR of the
2612 empty tconc pair to SCM_EOL instead of SCM_BOOL_F, avoiding the
2613 use of an improper list (which breaks g_print. g_print isn't
2615 guardians.c: Added more comments and modified the make-guardian
2616 docstring. Reordered a few procedures.
2618 2000-04-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
2620 * eval.c (scm_lookupcar1, scm_lookupcar, scm_m_case, scm_m_cond,
2621 scm_m_lambda, iqq, scm_m_define, scm_m_expand_body, unmemocopy,
2622 SCM_CEVAL), procs.h (SCM_TOP_LEVEL): Don't use C operators to
2625 (scm_makprom): Smob data is of type scm_bits_t.
2627 2000-03-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
2629 * backtrace.c (display_error_body), debug.c (scm_procedure_source,
2630 scm_reverse_lookup), dynl.c (scm_dynamic_link): Don't use C
2631 operators to compare SCM values.
2633 * debug.c (scm_make_debugobj), debug.h (SCM_DEBUGOBJ_FRAME,
2634 SCM_SET_DEBUGOBJ_FRAME): Update SCM_{SET_}?DEBUGOBJ_FRAME to
2635 access raw cell data with SCM_{SET_}?CELL_WORD_1.
2637 * debug.c (scm_make_debugobj): Don't use SCM_SETCAR to set types.
2639 * debug.c (scm_make_memoized), dynl.c (scm_dynamic_link): Smob
2640 data is of type scm_bits_t.
2642 2000-03-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
2644 * gdbint.c (gdb_maybe_valid_type_p), guardians.c (TCONC_EMPTYP,
2645 scm_guardian_zombify): Use SCM_EQ_P to compare SCM values.
2647 * guardians.c (GUARDIAN): Use SCM_CELL_WORD_1 for raw data.
2649 2000-03-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
2651 * ports.h (scm_port): Change type of stream member to scm_bits_t.
2653 * gdbint.c (unmark_port, remark_port), ports.c (scm_markstream),
2654 strports.c (st_resize_port, scm_mkstrport), vports (sf_flush,
2655 sf_write, sf_fill_input, sf_close, scm_make_soft_port): Since
2656 streams are now of type scm_bits_t, SCM streams have to be
2659 * ports.h (SCM_SETPTAB_ENTRY, SCM_SETSTREAM): Cast input to
2662 2000-03-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2664 * coop-defs.h (struct coop_t): Added `sto'-field again because of
2665 binary compatibility---let's remove it next time we alter some
2668 * coop.c (coop_quitting_p, coop_cond_create, coop_mutex_create,
2669 coop_mother, coop_child): New variables.
2670 (mother): New function.
2671 (coop_create): New thread spawning mechanism which uses a "mother
2672 thread". The "dummy" pthreads aren't healthy enough to give birth
2673 to new threads since Linux threads thinks they are asleep.
2675 * coop-defs.h (struct coop_t): Removed dummy_mutex.
2677 * coop-defs.h, coop-threads.c (struct coop_t): Eliminate
2678 `sto'-field when GUILE_PTHREAD_COMPAT is enabled.
2680 2000-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
2682 * arbiters.c (scm_make_arbiter), async.c (scm_async), dynwind.c
2683 (scm_internal_dynamic_wind): Smob data is always of type
2686 * arbiters.c (SCM_ARB_LOCKED, SCM_LOCK_ARB, SCM_UNLOCK_ARB):
2687 Access the locking information in cell entry 0 with
2688 SCM_{SET_}?CELL_WORD_0 instead of SCM_*CAR.
2690 * async.c (scm_run_asyncs): Use SCM_NULLP to test for the empty
2693 * dynwind.c (scm_dowinds): Use SCM_EQ_P to compare SCM values.
2695 * ports.h (SCM_PTAB_ENTRY, SCM_SETPTAB_ENTRY): Access the ptab
2696 entry data using SCM_{SET_}?CELL_WORD_1 instead of SCM_{SET}?CDR.
2698 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2700 * alist.c (scm_sloppy_assq, scm_assq), eq.c (scm_eq_p, scm_eqv_p,
2701 scm_equal_p), list.c (scm_ilength, scm_last_pair, scm_reverse,
2702 scm_sloppy_memq, scm_delq_x, scm_delq1_x), tags.h (SCM_UNBNDP):
2703 Don't use C operators == and != to compare SCM values, use
2706 * boolean.c (scm_boolean_p): Use SCM_BOOLP to determine whether a
2707 SCM value is equal to #t or #f.
2709 * eq.c (scm_eqv_p, scm_equal_p): Don't use SCM_CAR to access the
2710 cell type entry of non immediate objects of unknown type. Use
2711 SCM_CELL_TYPE instead.
2713 * gh_data.c (gh_scm2bool, gh_module_lookup), list.c
2714 (scm_sloppy_memv, scm_sloppy_member, scm_delv_x, scm_delete_x,
2715 scm_delv1_x, scm_delete1_x), scmsigs.c (scm_sigaction): Use
2716 SCM_FALSEP and SCM_TRUE_P to compare SCM values against #f and
2719 * list.c (scm_listify): Use SCM_UNBNDP to test for an unbound
2722 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2724 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread,
2725 scm_make_mutex, scm_make_condition_variable): Cast data to
2726 scm_bits_t in SCM_SET_CELL_WORD and SCM_NEWSMOB macros.
2728 * coop.c (coop_create): Set `specific' field, not `data' to NULL.
2730 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2732 * smob.h (SCM_NEWSMOB, SCM_NEWSMOB2, SCM_NEWSMOB3, SCM_SMOB_DATA,
2733 SCM_SET_SMOB_DATA, SCM_TC2SMOBNUM, SCM_SMOBNUM): To access smob
2734 data, use SCM_{SET_}?CELL_TYPE or SCM_{SET_}?WORD_[1-3].
2736 Note that this implies that smob data has always to be passed as
2737 values of type scm_bits_t.
2739 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2741 * threads.c (scm_init_threads): Pass 0 size to scm_make_smob_type
2742 for scm_tc16_thread. As the current COOP threads are written, GC
2743 is not supposed to manage storage for threads.
2745 * error.c (scm_error): Don't try to throw an error if
2746 scm_gc_heap_lock is true.
2748 * coop.c (coop_finish): New function. Called at exit.
2749 (coop_aborthelp): Free thread structures when threads die.
2750 Finished LinuxThreads compatibility support => COOP threads now
2751 mesh with LinuxThreads.
2753 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread):
2754 Changed SETCDR --> SET_CELL_WORD_1.
2756 * coop-threads.c (scheme_launch_thread): Set word 1 of handle to 0
2759 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2761 * boolean.h (SCM_TRUE_P): New macro.
2763 * boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP), pairs.h
2764 (SCM_NULLP, SCM_NNULLP): Use SCM_EQ_P to compare SCM values.
2766 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2768 * continuations.h (SCM_CONTREGS, SCM_SET_CONTREGS): New macros to
2769 access continuation data.
2771 (SCM_SETJMPBUF): Deprecated. Use SCM_SET_CONTREGS instead.
2773 (SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE, SCM_BASE, SCM_SEQ,
2774 SCM_DFRAME): Use SCM_CONTREGS instead of SCM_CHARS to access
2777 * continuations.c (scm_make_cont), init.c (start_stack),
2778 root.c (scm_internal_cwdr): Use SCM_SET_CONTREGS instead of
2781 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2783 * symbols.h (SCM_LENGTH, SCM_SETLENGTH): Access the length field
2784 of strings and symbols by using SCM_{SET_}?CELL_WORD_0.
2786 (SCM_CHARS, SCM_UCHARS, SCM_SETCHARS): Use SCM_{SET_}?CELL_WORD_1
2787 to access the char * field of strings and symbols.
2789 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2791 * gc.h (SCM_NEWCELL, SCM_NEWCELL2): Use SCM_SET_CELL_TYPE to set
2792 the type entry of a new cell. Added a comment about things to
2793 remember when updating the list of free cells.
2795 (SCM_FREEP, SCM_MARKEDP): Use SCM_CELL_TYPE to access the type
2798 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2800 * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR): Use
2801 SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT. This change implies that
2802 with strict type checking enabled these macros will only work if
2803 given valid SCM parameters.
2805 (SCM_GCCDR): Moved to tags.h.
2807 * tags.h (SCM_GCCDR): Moved here from pairs.h.
2809 2000-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
2811 * tags.h (SCM2PTR, PTR2SCM): Moved to gc.h.
2813 * pairs.h (scm_cell, SCM_CELLPTR, SCM_CELL_WORD*, SCM_CELL_OBJECT*,
2814 SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*, SCM_CELL_TYPE,
2815 SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK, SCM_PTR_GT,
2816 SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC, SCM_NEWCELL,
2817 SCM_NEWCELL2): Moved to gc.h.
2819 (SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR, SCM_SETAND_CDR,
2820 SCM_SETOR_CAR, SCM_SETOR_CDR): Moved to gc.h. These names should
2821 be changed, though, since the macros are not only pair related.
2825 * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,
2826 SCM_CELL_OBJECT*, SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*,
2827 SCM_CELL_TYPE, SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK,
2828 SCM_PTR_GT, SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC,
2829 SCM_NEWCELL, SCM_NEWCELL2, SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR,
2830 SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR): Moved here from
2833 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2835 * tags.h (SCM_STRICT_TYPING): New macro that, if defined,
2836 activates strict compile time type checking for variables of
2838 (SCM, SCM_PACK, SCM_UNPACK): Define according to whether
2839 SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
2840 (SCM_EQ_P): Defined as a macro equivalent for eq?.
2842 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2844 * tags.h (SCM_POINTERS_MUNGED): Removed.
2846 * gc.c (scm_gc_sweep, init_heap_seg): Removed use of
2847 SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
2849 2000-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
2851 * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
2852 SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
2853 SCM_SET_CELL_TYPE): Added a set of low level macros for accessing
2855 (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
2857 * procs.h, procs.c: Instead of SCM_{SET_}?CELL_WORD[12], use the
2858 newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
2860 2000-03-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2862 * tags.h: Disabled definition of SCM_VOIDP_TEST.
2864 Defining SCM as void * introduces problems which haven't been
2865 handled yet. Developers who work with these issues can enable it
2866 in their working copies.
2868 Disabling this definition exposes a set of newly introduced and
2869 older misuses of types which causes warning messages during
2870 compilation. We'll fix this successively.
2872 * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
2873 in order to obtain a value of type SCM.
2874 (scm_cellp): Updated with new changes to scm_mark_locations.
2876 * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
2878 * continuations.c (scm_make_cont): Removed cast of size_t into
2881 * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
2883 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2885 * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for
2886 shifting, not constant. Thanks to Dale P. Smith.
2888 * numbers.c (scm_sum, scm_difference): Don't test a SCM value
2889 for being less than zero. Decode it to a C value first. Again,
2892 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2894 * numbers.h, ramap.c, struct.h, vectors.h: Don't use SCM2PTR for
2895 non scheme values. If raw data is stored in SCM variables, it has
2896 to be accessed using SCM_UNPACK until a better solution is found.
2898 2000-03-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2900 * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
2901 pointer-arithmetic induced by the SCM_PACK/UNPACK change.
2903 * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
2905 * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
2907 * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
2909 * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
2911 * async.c, __scm.h: Removed lots of the old async click logic. It
2912 is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
2913 __scm.h. Let's try this out and dump the old code after the
2914 threads reorganization.
2915 (set-tick-rate, set-switch-rate): Conditionally removed.
2917 2000-03-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2919 * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
2920 made SCM values into pointers. This turned an arithmetic
2921 computation of the address of the vcell into a pointer-arithmetic
2922 one, thereby screwing up marking of structs.
2923 Bugfix 2: Removed incompletely introduced loop variable `j' used
2924 when protecting the tail array of a struct.
2926 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2928 * struct.h (SCM_STRUCT_DATA): Don't cast SCM values to pointers.
2930 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2932 * symbols.h, symbols.c (scm_strhash): Declare the string
2933 parameter as constant, since it is not modified.
2935 * symbols.c (scm_intern_obarray_soft,
2936 scm_sysintern0_no_module_lookup): Can now pass constant strings
2937 to scm_strhash without need for casting.
2939 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2941 * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS): Don't cast SCM
2942 values to pointers. Use SCM2PTR instead.
2944 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2946 * async.c (scm_set_tick_rate, scm_set_switch_rate): Don't unpack
2947 results of SCM_INUM.
2949 2000-03-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2951 * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
2952 GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
2953 GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
2955 * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
2956 min_yield_fraction, min_yield, adjust_min_yield): Renamed from
2957 SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
2958 gc_trigger, adjust_gc_trigger.
2960 * gc.c (alloc_some_heap): Further improvement of minimal heap size
2962 (SCM_MAX): New macro.
2963 (scm_freelist_t): New field: collected_1. Previous amount of
2965 (gc_sweep_freelist_finish): Trigger based on two last values of
2966 freelist->collected to avoid unnecessary allocation due to
2968 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
2969 Adjusted to 45000 cells, 40% and 40%. Gives quick startup
2970 without extra heap allocation.
2972 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2974 * numbers.h (SCM_MAKINUM): The parameter to SCM_MAKINUM should
2975 already be a C value. No need to unpack it.
2977 * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t
2978 if we know it fits into an inum.
2980 * ramap.c (ramap_rp): An scm_tc7_[ui]vect object does point to a
2981 field of long values. In contrast, SCM_VELTS accesses a field of
2984 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2986 * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
2988 (scm_gc_yield_1): New variable: Holds previous yield. Used to
2989 make better judgements.
2990 (gc_sweep_freelist_finish): Inserted explanation of use of
2993 * print.h, stacks.h, options.c, options.h: Changed C++
2996 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2998 * tags.h (SCM2PTR, PTR2SCM): Use SCM_PACK / SCM_UNPACK correctly.
3000 * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
3001 SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS): Use SCM_PACK /
3002 SCM_UNPACK / SCM2PTR correctly.
3004 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3006 * gc.c (adjust_gc_trigger): Improved documentation.
3007 (alloc_some_heap): Since gc_trigger is used against
3008 freelist->collected, this is the value which should be used to
3009 predict minimum growth.
3011 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
3013 * eval.h: Fix mixup of packed/unpacked SCM values. (Thanks
3014 Thien-Thi Nguyen for the patch.)
3016 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
3018 * numbers.c (scm_ash): Fixed typing problems with the second
3019 parameter and added some documentation. (Thanks Thien-Thi Nguyen
3020 for indicating the problem.)
3022 2000-03-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3024 * gc.c, gc.h (scm_gc_yield): New variable.
3025 (adjust_gc_trigger): Use scm_gc_yield.
3026 (alloc_some_heap): Use scm_gc_yield instead of
3027 scm_gc_cells_collected.
3029 * coop-threads.c: Addd #include "root.h", #include "strings.h".
3031 * debug.c: Added #include "root.h". (Thanks to Thien-Thi Nguyen.)
3033 * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
3034 trigger adjustmeant: Take yield (freed cells) for all freelists
3036 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
3037 to 50000 cell heap with 45% trigger.
3038 (scm_gc_cells_collected): Reintroduced.
3039 (SCM_HEAP_SIZE): New macro.
3040 (scm_gc_sweep): Reintroduced correct computation of
3041 scm_cells_allocated.
3042 (scm_freelist_t): Corrected commentary for field `cluster_size':
3043 Clustersize counts objects, not cells; New member
3044 `clusters_allocated'.
3046 2000-03-19 Michael Livshin <mlivshin@bigfoot.com>
3048 * *.[hc]: add Emacs magic at the end of file, to ensure GNU
3051 2000-03-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3053 * threads.h: Added #include "libguile/throw.h". (Thanks to
3056 2000-03-18 Michael Livshin <mlivshin@bigfoot.com>
3058 * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
3059 names, anyone got any better ones?)
3061 * gc.h: (typedef struct scm_freelist_t) remove from here.
3063 * gc.c: (CELL_UP, CELL_DN) made these macros take additional
3064 parameter (the span).
3065 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
3066 (typedef struct scm_freelist_t) moved here from gc.h, it had no
3067 business being externally visible.
3068 (typedef struct scm_heap_seg_data_t) renamed from
3069 scm_heap_seg_data, to be style-compliant.
3070 (scm_mark_locations) if the possible pointer points to a
3071 double-cell, check that it's properly aligned.
3072 (init_heap_seg) align double-cells properly, work with the
3073 assumption that the segment size divides cleanly by cluster size.
3074 (round_to_cluster_size) new function.
3075 (alloc_some_heap, make_initial_segment) use round_to_cluster_size
3076 to satisfy the new init_heap_seg invariant.
3078 2000-03-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
3080 * _scm.h: Don't include async.h everywhere...

3135 2000-03-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3137 * gc.c, gc.h: Cleanup of the change of 2000-03-15.
3138 Cluster sizes are now independent of GC trigger values.
3139 GUILE_GC_TRIGGER_n can now specify a relative trigger value:
3140 A negative integer gives fraction of total heap size in percent.
3141 (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
3143 * init.c (scm_boot_guile_1): Introduced new variable
3144 GUILE_MAX_SEGMENT_SIZE; New environment variable names:
3145 GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
3146 GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
3148 2000-03-16 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3150 * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
3151 freeing of segment work with the new GC scheme. (Thanks to
3152 Michael Livshin.) Oops, also happened to make GUILE_NEW_GC_SCHEME
3153 the default, but I'll let this change stay in CVS Guile since this
3154 code is not expected to contain serious bugs.
3156 2000-03-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3158 * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
3160 (scm_free_list_length): New procedure (GUILE_DEBUG).
3161 Fixed a small but serious bug introduced by the previous change.
3163 * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
3164 loop and declare as register.
3166 * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
3169 Wed Mar 15 08:27:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3171 * fluids.c: Docstring patch from Keisuke Nishida. Some
3172 reindentation, too, and a couple formals renamed. Should
3173 fluid-set! return UNSPECIFIED instead of a value?
3175 Wed Mar 15 08:24:58 2000 Greg J. Badros <gjb@cs.washington.edu>
3177 * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
3178 generate the latter from the concrete listing of the former. Then
3179 make guile-procedures.txt depend on DOT_DOC_FILES instead of
3180 *.doc, so that rebuilding it works.
3182 Wed Mar 15 08:12:14 2000 Greg J. Badros <gjb@cs.washington.edu>
3184 * libguile.h: Include libguile/validate.h. Thanks Keisuke Nishida!
3186 * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
3187 with nothing and \n, respectively. Thanks Keisuke Nishida for
3188 noticing this problem.
3190 2000-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3192 * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
3193 new way of allocating heap. It makes Guile fast, but still
3196 * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
3197 allocating heap. The basic idea is to trigger GC every Nth
3198 allocated cell and grow heap when free list runs out. The scheme
3199 has been extended so that GC isn't triggered until all remaining
3200 cells are used. The implementation is also prepared for
3201 development in the direction of POSIX threads.
3203 * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
3204 SCM_EXPHEAP should return half of the heap size.
3206 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3208 The following change to init.c is only enabled if Guile was
3209 configured with --enable-guile-debug.
3211 * init.c (scm_i_getenv_int): New function.
3212 (scm_boot_guile_1): Use the environment variables
3213 GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
3214 they exist. (This may be replaced by a Scheme level mechanism in
3217 * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
3218 scm_assoc. (Thanks to Keisuke Nishida.)
3220 2000-03-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3222 * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
3223 scm_nil, scm_t. (Thanks to Keisuke Nishida.)
3225 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3227 * init.c (scm_boot_guile_1): Use same initial segment size for
3228 1-word and 2-word segments. Having the smaller size causes Guile
3229 to GC too often. Obviously something needs to be done to allow
3230 for a smaller 2-word segment without this to happen. (The amount
3231 of heap for each type should be automatically adapted to the
3232 application somehow.)
3234 [Almost all of these changes should be documented in the NEWS
3237 * gc.h (scm_freelist_t): New type.
3239 * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
3241 * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
3242 all of Guile basics fits into one segment and there suitable room
3244 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
3246 (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
3247 Freelists now contains information about object span, cells
3248 collected and amount of cells in heap segments belonging to the
3250 (scm_heap_size, scm_gc_cells_collected): Removed.
3252 * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
3254 * Makefile.am (libguile_la_LDFLAGS): Bumped library version
3257 * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
3258 numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
3259 rewrite of handling of real and complex numbers.
3260 (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
3261 removed along with the support for floats. (Float vectors are
3264 * tags.h (scm_tcs_bignums): Removed.
3265 (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
3266 Use SCM_BIGSIGN(x) to test for sign!
3267 (scm_tc16_big): The new bignum type.
3268 (SCM_REAL_PART, SCM_IMAG_PART): Removed.
3270 * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
3271 (scm_makdbl): Deprecated.
3272 (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
3273 (SCM_SINGP): Deprecated.
3275 (SCM_INEXP, SCM_CPLXP): Deprecated.
3276 (SCM_INEXACTP, SCM_COMPLEXP): New macros.
3277 (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
3278 SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
3279 (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
3280 for doubles and complex numbers.
3281 (SCM_REAL_VALUE): New selector for doubles.
3282 (scm_double_t, scm_complex_t): New types.
3285 * numbers.c (scm_floprint, scm_floequal): Removed.
3286 (scm_print_real, scm_print_complex, scm_real_equalp,
3287 scm_complex_equalp): New functions.
3289 * unif.c (scm_makflo): Removed.
3291 * smob.h (SCM_SMOB_PREDICATE): New macro.
3292 (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
3293 SCM_RETURN_NEWSMOB3): New macros.
3295 1999-11-21 Michael Livshin <mlivshin@bigfoot.com>
3297 The following changes implement primitive support for double cells
3298 (i.e. four-word cells) and change the representation of some
3299 things to multi-cells instead of cons+malloc. (Applied and
3302 * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
3303 (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
3304 multi-cell access macros (used by the ones below).
3305 (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
3308 * gc.c (scm_freelist2): multi-cell freelists.
3309 (inner_map_free_list): map_free_list, parameterized on ncells.
3310 "nn cells in segment mm" was misleading for ncells > 1; changed to
3311 "objects". still print cells too, though.
3312 (scm_map_free_list): rewritten using inner_map_free_list.
3313 (scm_check_freelist): get freelist as parameter, since now we have
3315 (scm_debug_newcell2): multi-cell variants of
3317 (scm_gc_for_newcell): take ncells and freelist pointer as
3319 (scm_gc_mark): add case for tc7_pws (procedures with setters are
3321 (scm_gc_sweep): don't free the float data, since it's not malloced
3323 (init_heap_seg): didn't understand what n_new_objects stood for,
3324 so changed to n_new_cells.
3325 (make_initial_segment): new function, makes an initial segment
3326 according to given ncells.
3327 (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
3329 * numbers.c (scm_makdbl): no malloc'ing needed, so the
3330 {DEFER,ALLOW}_INTS thing removed.
3332 * numbers.h (struct scm_dbl): changed to represent a double cell,
3333 with the number in the second half.
3335 * dynwind.c: changed the wind-guards representation to double
3338 * procs.c, procs.h: changed the procedure-with-setter representation
3341 * async.c, async.h: made async representation a double cell.
3343 * dynl.c: made dynamic_obj representation a double cell.
3345 2000-03-13 Gary Houston <ghouston@arglist.com>
3347 * ports.c (flush_void_port): renamed to flush_port_default.
3348 (end_input_void_port): renamed to end_input_default.
3350 * init.c (scm_standard_stream_to_port): create a void port instead
3351 of opening /dev/null if the standard file descriptors are bad.
3352 advantages: no portability problems, doesn't waste a file descriptor,
3353 simplifies the code (thanks to Marius for the idea).
3355 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
3357 * void ports: make reading from a void port give EOF instead of
3359 * ports.c (s_scm_sys_make_void_port): modified docstring.
3360 (fill_input_void_port): new proc.
3361 (scm_init_ports): set up fill_input_void_port.
3362 * ports.c (scm_port_non_buffer): new proc.
3363 (scm_void_port): call scm_port_non_buffer.
3365 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
3366 which was incorrectly appended.
3368 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3370 * guile-doc-snarf.in: Don't use absolute path for `sed'. (Note
3371 that we can't use autoconf for this. Autoconf itself relies on
3372 the existence of `sed' somewhere on your path.) (Thanks to Dirk
3375 2000-03-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3377 * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
3378 EXTRA_libguile_la_SOURCES.
3380 * iselect.h: Always declare scm_internal_select.
3382 * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
3383 end. Also let scm_internal_select be a real function also when
3386 * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
3388 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3390 * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
3391 SCM_ASYNC_TICK. (This is a preparation for POSIX threads support,
3392 and kind of an experiment: Will this cause problems?)
3394 Sun Mar 12 13:26:30 2000 Greg J. Badros <gjb@cs.washington.edu>
3396 * Makefile.am: Added *.doc to DISTCLEANFILES.
3398 2000-03-12 Gary Houston <ghouston@arglist.com>
3400 * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
3401 the fdes is valid before doing anything else. check that
3402 the file descriptor supports the modes required.
3403 (scm_fport_buffer_add): don't throw an error if fstat doesn't
3404 work: just use the default buffer size.
3406 * throw.c: change an outdated comment about scm_internal_catch
3407 BODY: it doesn't take a jumpbuf arg.
3409 * init.c (scm_standard_stream_to_port): install a handler in case
3410 scm_fdes_to_port throws an error. don't check here whether the
3411 file descriptor is valid, since scm_fdes_to_port will do that.
3412 set the revealed count depending on whether the port got the
3413 standard file descriptor.
3414 (stream_body_data): new type.
3415 (stream_body, stream_handler): new procs.
3417 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3419 * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
3420 Renamed from SCMWORD.
3422 * tags.h (SCM_NCELLP): Removed (SCMWORD).
3424 * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
3426 * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
3427 feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,

3432 throw.c, unif.c, unif.h, variable.h, vectors.h, weaks.c,
3433 weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
3434 SCM_ASSCM, SCM_ASWORD, SCM_CARW).
3436 * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
3438 * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
3439 tags.h: Fixed copyright notices.
3441 * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
3443 2000-03-12 Marius Vollmer <mvo@zagadka.ping.de>
3445 * init.c (scm_standard_stream_to_port): Check whether the file
3446 descriptor is valid and substitute "/dev/null" when not.
3448 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3450 * coop-defs.h (struct timespec): Conditionally defined.
3452 * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
3455 * readline.c (match_paren): Bugfix: First arg to select is not
3456 number of descriptors but the number of the highest descriptor +
3459 This is a preliminary attempt at a cleanup of the threads support
3460 code. It moves things to better places, makes arguments more
3461 consistent with the POSIX API (which is used in GNOME's glib), and
3462 adds new functionality.
3464 * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
3466 * coop-defs.h (scm_mutex_trylock): New macro: alias for
3468 (scm_cond_init): Changed definition to
3469 coop_new_condition_variable_init.
3471 * coop.c: #include <errno.h>
3472 (coop_timeout_qinsert): Moved here from iselect.c
3473 (coop_new_mutex_init, coop_new_condition_variable_init): New
3474 functions. The strange names are temporary. Use scm_mutex_init
3475 and scm_cond_init instead.
3476 (coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
3477 is ANSI C, but should we check for individual error codes in
3479 (coop_condition_variable_timed_wait_mutex): New function.
3480 (coop_key_create, coop_setspecific, coop_getspecific,
3481 coop_key_delete): New functions.
3483 * iselect.c (coop_timout_qinsert): Moved to coop.c
3485 2000-03-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3487 * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
3488 SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
3490 * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
3493 * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
3494 SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
3495 proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
3497 * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
3500 2000-03-11 Dale P. Smith <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
3502 * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
3503 scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
3504 logical functions from SCM.
3506 (logand, logior, logxor, logtest, logbit?): Extended scheme
3507 logical functions to use bignums from SCM.
3509 (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
3510 lognot from using bignums.
3512 Thu Mar 9 11:33:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3514 * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
3515 eliminating some warnings.
3517 * unif.c, strports.c, print.c, options.c: Fix some warnings on
3520 * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
3521 what the scm_return_first* functions do.
3523 2000-03-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
3525 * libguile/*.[ch]: make a distinction between SCM as a generic
3526 name for a Scheme object (now a void*), and SCM as 32 bit word for
3527 storing tags and immediates (now a long int). Introduced
3528 SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
3529 code in the process: arbiter.c (use macros), unif.c (scm_array_p),
3531 Wed Mar 8 10:15:59 2000 Greg J. Badros <gjb@cs.washington.edu>
3533 * numbers.c: Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
3534 various logXXX primitives. Thanks Eric Moore!
3536 Tue Mar 7 08:05:22 2000 Greg J. Badros <gjb@cs.washington.edu>
3538 * run-test, remaining-docs-needed: Added these scripts. The
3539 second one is only temporary until the docstring additions are
3540 complete. run-test may best live on, but is here mostly for
3541 convenience and awareness for now.
3543 * hash.c: Docs, minor cleanup patch from Dirk Herrman.
3545 Thu Mar 2 16:06:58 2000 Greg J. Badros <gjb@cs.washington.edu>
3547 * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
3548 displaying the expected type. Use SCM_LISTn in a couple places
3549 instead of scm_cons-ing by hand.
3551 * __scm.h: Added SCM_ASSERT_TYPE macro.
3553 * validate.h, scm_validate.h: Added the former, as a renamed
3554 version of the latter with SCM_ASSERT_TYPE used in
3555 SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
3557 * Makefile.am: Rename scm_validate.h to validate.h.
3559 * *.c, *.h: Include validate.h, not scm_validate.h (old name's
3560 prefix was superfluous).
3562 Thu Mar 2 15:33:12 2000 Greg J. Badros <gjb@cs.washington.edu>
3564 * hashtab.c: Improved documentation for lots of functions. Added
3565 handwritten docs for `hash-fold'.
3567 Thu Mar 2 15:13:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3569 * list.c: Added hand-written docs for `del{q,v,ete}1!'.
3571 Thu Mar 2 12:38:30 2000 Greg J. Badros <gjb@cs.washington.edu>
3573 * list.c: Moved append docs to append! Thanks Dirk Hermann. Also,
3574 added append docs from R4RS.
3576 * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
3577 Thanks Dirk Hermann!
3579 * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
3580 deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
3582 * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
3583 Drop use of SCM_P for function prototypes... assume an ANSI C
3584 compiler. Thanks Dirk Hermann!
3586 Sat Feb 19 12:20:12 2000 Greg J. Badros <gjb@cs.washington.edu>
3588 * ports.c: Made `set-port-column!' and `set-port-line!' each
3589 return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
3590 that caused a seg fault. Also fixed `set-port-column!'s
3591 docstring. Thanks Han-Wen Nienhuys for finding the bug!
3593 Sun Feb 13 19:11:42 2000 Greg J. Badros <gjb@cs.washington.edu>
3595 * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
3596 regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
3597 strings.c, variable.c: Added lots of documentation, cleaned up
3598 some existing documentation. Occasionally changed formal params
3599 to match docs. Also folded an #ifdef into the inners of a
3600 primitive instead of having two copies of the primitive
3601 (`get-internal-real-time', from stime.c)
3603 Sun Feb 13 18:12:19 2000 Greg J. Badros <gjb@cs.washington.edu>
3605 * ports.c: Added docs for primitives missing them. Written by
3608 Sun Feb 13 09:40:36 2000 Greg J. Badros <gjb@cs.washington.edu>
3610 * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
3611 just execing guile-func-name-check. Thanks Michael Livshin!
3613 Thu Feb 10 11:43:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3615 * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
3616 dead code. Patch from Michael Livshin.
3618 * guile-doc-snarf.in: Tweak to work with Sun/HP sh. Patch from
3621 2000-02-09 Gary Houston <ghouston@arglist.com>
3623 * init.c (scm_init_standard_ports): when stdout is a tty, make the
3624 current-output-port unbuffered by default. this is less confusing
3625 for interactive use. it was line-buffered because of a
3626 performance problem with unbuffered ports, but I think it will be
3629 2000-02-08 Gary Houston <ghouston@arglist.com>
3631 * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
3634 * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
3635 HAVE_TZNAME are defined, use an empty string instead of giving two
3636 spurious compile-time errors.
3638 Tue Feb 8 13:57:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3640 * ports.c: Doc patches from Richard Kim. Pasted from MIT Scheme.
3643 Mon Feb 7 09:07:31 2000 Greg J. Badros <gjb@cs.washington.edu>
3645 * macros.c: Doc patches from Richard Kim. Pasted from scm.texi.
3647 Sun Feb 6 20:26:21 2000 Greg J. Badros <gjb@cs.washington.edu>
3649 * pairs.c: Doc patches from Richard Kim. Pasted from MIT Scheme
3650 (which is GNU GPL'd).
3652 2000-01-31 Gary Houston <ghouston@arglist.com>
3654 * strings.h: don't use SCM_P. don't include <string.h>.
3655 * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
3657 * strings.c (scm_string_ref): make the 2nd argument compulsory.
3658 previously it defaulted to zero for no good reason that I can see.
3659 use a local variable for SCM_INUM (k). replace
3660 SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
3662 (scm_makfromstr): cosmetic changes.
3664 (scm_string): Accept only chars in the list, not strings, for
3665 conformance to R5RS (particularly for list->string, which is
3666 supposed to be the inverse of string->list.) remove
3667 SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
3668 scm_makstr handles the cell allocation. when reporting wrong-type
3669 arg, don't report the position as 1.
3671 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
3673 2000-01-29 Gary Houston <ghouston@arglist.com>
3675 * posix.c (scm_pipe): rewrote the docstring.
3677 * filesys.c (scm_select, retrieve_select_type, get_element,
3678 fill_select_type, set_element): modified so that Scheme
3679 "select" tests port buffers for the ability to provide input
3680 or accept output. Previously only the underlying file descriptors
3681 were checked. Rewrote the docstring.
3683 Thu Jan 27 10:14:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3685 * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
3686 from Gregg Reynolds. Thanks Gregg!
3688 Thu Jan 27 09:59:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3690 * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
3691 adding "x" prefix to the line so that guile-func-name-check
3692 doesn't complain unnecessarily.
3694 Wed Jan 26 17:33:52 2000 Greg J. Badros <gjb@cs.washington.edu>
3696 * throw.c: Factor out an #ifdef/#else/#endif choice more finely
3697 for maintainability.
3699 * strop.c: Documentation added by Gregg A. Reynolds. Pasted in
3702 Wed Jan 26 10:02:11 2000 Greg J. Badros <gjb@cs.washington.edu>
3704 * tag.c: Added doc for `tag', but mark as deprecated since Mikael
3705 suggests removing tag.c altogether (and using a new `class-of'
3708 * strings.c: Added documentation from Gregg A. Reynolds. Edited
3709 a bit by me to use FOO instead of @var{foo} and to have the
3710 summary come before preconditions on input. Also dropped trailing
3713 * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
3714 function with scm_make_subr_opt w/ last arg of 0 so it is not
3715 visible at the Scheme level. Mikael says that this is the right
3716 thing because the first arg to the proc is the guts of a compiled
3717 closure and shouldn't be exposed to the Scheme level.
3719 Tue Jan 25 17:15:47 2000 Greg J. Badros <gjb@cs.washington.edu>
3721 * sort.c: typo in comment fixed.
3723 * keywords.c: Added documentation.
3725 * guardians.c: Added documentation (could be better).
3727 * gc.c: Added docs for gc-set-debug-check-freelist.
3729 * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
3731 * boolean.c: Added docs for `not', `boolean?' (by hand).
3733 Tue Jan 25 13:28:56 2000 Greg J. Badros <gjb@cs.washington.edu>
3735 * random.c: Added documentation, from SLIB page:
3736 http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
3738 Mon Jan 24 17:50:20 2000 Greg J. Badros <gjb@cs.washington.edu>
3740 * variable.c, version.c: Added documentation, written by hand
3741 since I could not find anything already written that was
3744 2000-01-23 Gary Houston <ghouston@arglist.com>
3746 * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
3747 not defined (thanks to Richard Y. Kim).
3749 Thu Jan 20 13:00:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3751 * Makefile.in: Removed, this is auto-generated.
3753 Thu Jan 20 11:33:47 2000 Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
3755 * list.c: Put some variable initialization code at the point of
3756 declaration; Added a comment for list*; Formatting changes.
3758 * load.c: use SCM_NNULLP to make sure the end of a list is not
3761 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3763 * backtrace.c (scm_display_error_message): Bugfix: Don't use
3764 result of scm_list_p as C boolean.
3765 (scm_display_error_message, scm_set_print_params_x): Use new
3766 validation macros. (Thanks to Dirk Herrmann.)
3768 * net_db.c (scm_resolv_error): Cast result from hstrerror.
3770 * strports.c (st_end_input): Inserted parenthesis to get operator
3773 * list.h (scm_init_list): Removed SCM_P around prototypes.
3775 * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
3776 filesys.c, posix.c: Converted docstrings to ANSI C format and
3777 escaped " occurring inside string literals.
3779 Tue Jan 18 13:21:08 2000 Mikael Djurfeldt <mdj@r11n07-s.pdc.kth.se>
3781 * posix.c (scm_mknod): Escape " occuring inside docstring.
3783 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3785 * alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,
3786 evalext.c, filesys.c, gc.c, hash.c, hashtab.c, ioext.c,
3787 keywords.c, list.c, load.c, macros.c, net_db.c, numbers.c,
3788 objprop.c, ports.c, posix.c, print.c, procprop.c, procs.c,
3789 ramap.c, regex-posix.c, root.c, scmsigs.c, simpos.c, socket.c,
3790 stacks.c, stime.c, strings.c, strop.c, strports.c, struct.c,
3791 symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
3792 weaks.c: Converted docstrings to ANSI C format.
3794 * filesys.c (scm_chmod), simpos.c (scm_system), version
3795 (scm_version), vports (scm_make_soft_port): Escape " occuring
3798 Mon Jan 17 11:41:22 2000 Greg J. Badros <gjb@cs.washington.edu>
3800 * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
3801 SCM_VALIDATE_LONG_COPY
3803 * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
3804 SCM_VALIDATE_INUM_COPY to let bigger numbers be used. Rename a
3805 couple of formal arguments (and fix their uses) to make arguments
3806 match the documentation.
3808 2000-01-14 <mstachow@alum.mit.edu>
3810 * Makefile.am: Augment path when running guile-doc-snarf so
3811 guile-func-name-check is found.
3813 Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
3815 * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
3816 def, not SCM_MAKINUM(def); thanks Janis Bzerins!
3818 Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3820 * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
3821 the way guile-1.3.4 worked, but #if 0 out the version using
3822 SCM_VALIDATE_INUM_COPY for stricter testing.
3824 Tue Jan 11 18:24:18 2000 Greg J. Badros <gjb@cs.washington.edu>
3826 * guile-doc-snarf.in: Use new $fullfilename for running
3827 guile-func-name-check, and put "$fullfilename" and "$filename" in
3828 quotes at uses to make sure re-splitting on whitespace does not
3829 occur (so filenames w/ embedded whitespace would work okay, though
3830 I sure hope we never have to deal with that! :-) ). Thanks to
3831 Mikael for pointing out the source_dir != build_dir was broken.
3833 Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
3835 * scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
3836 SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
3837 SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
3838 macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
3841 * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
3842 then return whether it's an open port (was validating that it was
3843 an open port -- this was a bug I introduced back in December, but
3844 my careful reading of diffs caught it).
3846 * numbers.c: Recombine the two conditional-compilation paths for
3847 all the log* primitives -- they were split based on #ifndef
3848 scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
3849 some bugs and inconsistencies in the two sets of implementations.
3850 (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
3852 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
3853 SCM_VALIDATE_INUM_COPY once where it should've been used.
3855 * fluids.c (scm_internal_with_fluids): Use
3856 SCM_VALIDATE_LIST_COPYLEN.
3858 * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
3859 this is questionable as it relaxes type safety, but other changes
3860 were useful and all SCM_NUM2LONG's should probably be
3861 revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
3863 * evalext.c: line-break change on 1 line.
3865 * eval.c (nconc2last): Takes a non-empty list as its first
3866 argument, not just a list.
3868 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
3870 Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3872 * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
3873 net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
3876 * symbols.c (scm_sysintern0): Fixed the function name in a
3877 scm_misc_error invocation.
3879 * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
3880 use scm_return_first to ward off latent GC bug that Mikael caught.
3882 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
3883 used before but should've been.
3885 2000-01-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3887 * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
3888 SCM_FUNC_CAST_ARBITRARY_ARGS.
3890 Tue Jan 11 13:44:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3892 * guile-func-name-check.in: Added this script to statically check
3893 #define FUNC_NAME, #undef FUNC_NAME in the source.
3895 * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
3896 redundant comment, semicolon; caught by new guile-func-name-check
3899 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
3900 Caught by new guile-func-name-check-script.
3902 * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
3904 * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
3905 guile-func-name-check.
3907 * guile-doc-snarf.in: Run guile-func-name-check on the file before
3910 Tue Jan 11 11:31:10 2000 Greg J. Badros <gjb@cs.washington.edu>
3912 * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
3913 port function take const void*, not void*.
3915 Tue Jan 11 11:18:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3917 * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
3918 strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
3919 SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
3920 consistency with the other macros dealing with immediate
3921 characters. (Similar to INT -> INUM change a week or so ago).
3923 Tue Jan 11 10:41:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3925 * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
3926 net_db.c, read.c, socket.c: Update error messages to use ~A for
3927 %s, ~S for %S to work with new `simple-format' format and be
3928 standardized better.
3930 * print.h, print.c (scm_simple_format): Added `simple-format'
3931 primitive. It's the old scm_display_error, with ARGS now a rest
3932 parameter, and the destination first instead of last (and a couple
3933 new capabilities inspired by `format' -- #t as destination means
3934 current-output-port, #f means return the formatted text as a
3937 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
3939 * backtrace.c (scm_display_error_message): Rewrote to use
3940 scm_simple_format() procedure.
3942 * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
3944 2000-01-09 Marius Vollmer <mvo@zagadka.ping.de>
3946 Finally applied the libltdl patch from Thomas Tanner, with slight
3949 * DYNAMIC-LINKING: Removed because it is obsolete.
3950 * dynl.c: Use ANSI prototypes.
3951 (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
3952 * scmconfig.h.in: Do not change, as it is automatically generated.
3954 1999-07-25 Thomas Tanner <tanner@ffii.org>
3956 * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
3958 * Makefile.am: likewise, add INCLTDL (libltdl headers) to
3959 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
3961 * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
3962 * guile.c: register preloaded modules
3963 * scmconfig.h.in: remove obsolete symbols
3965 2000-01-09 Gary Houston <ghouston@arglist.com>
3967 * These changes should make it unnecessary to call tzset from
3968 Scheme after modifying the TZ environment variable, even if the
3969 system date facilities cache the value.
3970 * stime.c (setzone, scm_localtime): added comments.
3971 (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
3972 (setzone): don't call tzset.
3973 (restorezone): call tzset only if HAVE_TZSET is defined.
3974 (scm_tzset): don't define if HAVE_TZSET not defined. Change the
3975 doc string to indicate that this procedure isn't likely to do
3977 (scm_localtime, scm_strftime, scm_mktime): call tzset if
3978 LOCALTIME_CACHE is defined.
3980 2000-01-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3982 * posix.c (scm_sync): Return SCM_UNSPECIFIED.
3984 2000-01-09 Gary Houston <ghouston@arglist.com>
3986 * eval.c: define scm_unbound_variable_key ('unbound-variable).
3987 scm_lookupcar1: throw an error with key 'unbound-variable instead
3988 of 'misc-error when an unbound variable is encountered.
3990 * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
3991 scm_symlink, scm_readlink, scm_lstat),
3992 posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
3993 scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
3995 simpos.c (scm_system),
3996 stime.c (scm_times, scm_strptime):
3997 move the HAVE_XXX feature tests out of the procedure bodies.
3998 don't use SCM_SYSMISSING.
3999 scm_validate.h (SCM_SYSMISSING): removed.
4000 error.h, error.c (scm_sysmissing): comment that this is deprecated.
4001 see ChangeLog entry for 1999-12-28.
4003 Sat Jan 8 19:52:04 2000 Greg J. Badros <gjb@cs.washington.edu>
4005 * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
4007 Sat Jan 8 17:06:46 2000 Greg J. Badros <gjb@cs.washington.edu>
4009 * backtrace.c: Fix spelling typo in a comment.
4011 * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
4012 text. Reformatted some of the expansions.
4014 Fri Jan 7 15:50:46 2000 Greg J. Badros <gjb@cs.washington.edu>
4016 * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
4017 report the position of the argument.
4019 * error.h, error.c (scm_out_of_range_pos): Added this function to
4020 take extra "pos" argument, the position number of the errant
4023 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
4025 * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
4026 and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
4027 prefers that and I'm reasonably indifferent.
4029 Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
4031 * snarf.h: Factor out differences between C++ and non-C++ into
4032 SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
4033 definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
4034 Mikael's macros, below, but changed names and SCM_SNARFING no
4035 longer expands to include %%% -- that must appear in the argument
4036 so that the token appears at the call-site as a reminder).
4038 2000-01-07 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
4040 * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
4041 snarf macro definitions.
4043 2000-01-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4045 * chars.c (scm_integer_to_char): Use Greg's nice
4046 SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
4049 Thu Jan 6 11:48:49 2000 Greg J. Badros <gjb@cs.washington.edu>
4051 * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
4053 Thu Jan 6 11:22:53 2000 Greg J. Badros <gjb@cs.washington.edu>
4055 * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
4056 instead of GUILE_PROC.
4058 Thu Jan 6 11:21:49 2000 Greg J. Badros <gjb@cs.washington.edu>
4060 * alist.c: Do not report mismatch errors on some uses of `tmp' (do
4061 this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
4064 Thu Jan 6 09:54:33 2000 Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
4066 * scm_validate.h: Remove some redundant NIMP tests.
4068 * alist.c: minimize scope of the tmp variables, and initialize
4069 them when declared. The strange SCM_NIMP tests are replaced by
4070 SCM_CONSP tests that more closely reflect the intended semantics.
4071 However, we don't get a performance penalty here, because the
4072 SCM_CONSP test was performed by the ALISTCELL test anyway. * The
4073 extremely ugly use of ASRTGO macros was removed: The calls to
4074 ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
4075 label parameter that only exists when SCM_RECKLESS is not defined.
4076 This works, because ASRTGO itself is defined in a way that it only
4077 makes use of the label parameter if SCM_RECKLESS is not defined
4078 (shudder!). Does guile make at all use of the possibility to
4079 define SCM_RECKLESS? * Codesize is likely to be reduced, since
4080 instead of two calls to SCM_ASSERT performed by the ALISTCELL test
4081 we now only get one test.
4083 * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
4084 SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
4085 some variables in `list?'. Fix `reverse' and `reverse!'
4086 primitives to handle improper lists better.
4088 Wed Jan 5 11:24:53 2000 Greg J. Badros <gjb@cs.washington.edu>
4090 * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
4091 macros and SCM_DEFINE macros to match GNU coding standards.
4093 Wed Jan 5 11:04:24 2000 Greg J. Badros <gjb@cs.washington.edu>
4095 * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
4097 Wed Jan 5 10:59:06 2000 Greg J. Badros <gjb@cs.washington.edu>
4099 * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
4100 better consistency with the names of other SCM_VALIDATE_ macros
4101 and better conformance to guile naming policy.
4103 Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
4105 * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
4106 SCM_VALIDATE instead of 1 to avoid a check on the argument (since
4107 it's not the actual name of the formal).
4109 * guile-snarf.awk.in: Do argument/number mismatch checking and
4110 print warnings in an Emacs compile-mode parseable format.
4112 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
4113 SCM_OUTOFRANGE as 3rd argument.
4115 * random.c: Fix argument/number mismatch (that I introduced :-( ).
4117 * __scm.h: Do not #define SCM_ARG* when snarfing;
4118 lets us distinguish between 1 and SCM_ARG1 when snarfing as only
4119 the former (using the number) requires the argument to match the
4120 formal in the current argument snarfing check.
4122 * snarf.h: Give new definition of SCM_ASSERT when in
4123 snarfing mode to output a lexically-identifiable sequence that the
4124 guile-snarf.awk script uses to verify argument/position matching.
4126 * ramap.c: Remove extraneous #undef FUNC_NAME.
4128 Wed Jan 5 08:36:38 2000 Greg J. Badros <gjb@cs.washington.edu>
4130 * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
4131 current version of the same functionality; it writes the .x output
4132 to stdout instead of directly into the file.
4134 Wed Jan 5 08:15:04 2000 Greg J. Badros <gjb@cs.washington.edu>
4136 * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
4137 posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
4138 redundant with the safer macros. Patch from Dirk Hermann applied
4139 by hand. Thanks Dirk!
4141 * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
4144 * ramap.c: whitespace change.
4146 Tue Jan 4 14:21:35 2000 Greg J. Badros <gjb@cs.washington.edu>
4148 * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
4149 removals from Dirk Hermann.
4151 * alist.c: Rename formals to match the parameter names in the
4152 documentation, updates to documentation. Thanks Dirk Hermann!
4154 2000-01-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4156 * eval.c (SCM_CEVAL): Reverse order of
4157 scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
4158 (Thanks to Brad Knotwell.)
4160 Mon Jan 3 08:30:02 2000 Greg Harvey <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
4162 * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
4165 * pairs.h: Added a comment about the need for the SCM_SETCAR in
4168 Mon Jan 3 08:25:19 2000 Greg J. Badros <gjb@cs.washington.edu>
4170 * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
4171 SCM_NIMP tests that were redundant are now eliminated. Patches
4172 from Dirk Hermann applied by hand.
