7
8 * filesys.c (scm_stat2scm), posix.c (s_scm_mknod): don't use

12
13 * Makefile.am (guile-procedures.txt): Insert a new rule such that
14 the output from guile-snarf.awk is processed by makeinfo to

18 the output is Texinfo-compliant and suitable for post-processing
19 with makeinfo. (Trim leading "./" from C file name if

21 improve representation of args to show optional and rest args;
22 explicitly quote quotation marks where they are used inside an AWK
23 regexp.)

209
210 * numbers.c (scm_istr2flo): Throw an `out of range' error when

228
229 2000-09-14 Gary Houston <ghouston@arglist.com>
230
231 * print.c (scm_iprin1): write the ascii delete character as #\del
232 instead of '#\', so it can be read back. like in SCM.
233
234 2000-09-12 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
235
236 * symbols.c (duplicate_string): Don't try to copy the byte after
237 the string. This might not be `\0' and might even not be
238 allocated memory.
239
240 2000-09-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
241
242 * symbols.c (scm_symbol_p): Eliminate redundant SCM_IMP test.
243
244 2000-09-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
245
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.
254
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.

260
261 (scm_gc_sweep): There are no symbol slots any more.
262
263 * hash.c (scm_hasher): Instead of re-calculating the hash value
264 of a symbol, use the raw_hash value stored in the symbol itself.
265
266 * properties.h: Fix typo.
267
268 * strings.[ch] (scm_makstr, scm_makfromstr): The slot parameter
269 is not used any more.
270
271 * symbols.[ch] (scm_strhash): Deprecated, replaced by a macro.
272
273 (scm_intern_obarray_soft): Made softness parameter unsigned.
274
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.
278
279 * symbols.c (duplicate_string): New static convenience function.
280
281 (scm_sym2vcell, scm_sym2ovcell_soft, scm_intern_obarray_soft):
282 Renamed local variable from scm_hash to hash.
283
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.
287
288 (scm_symbol_to_string): Removed unnecessary cast.
289
290 (scm_intern_symbol, scm_unintern_symbol): Use scm_string_hash to
291 determine the hash values.
292
293 (msymbolize): Removed.
294
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.
298
299 (scm_symbol_hash): Comment fixed.
300
301 * symbols.h: Comment about the distinction between ssymbols and
302 msymbols removed.
303
304 (SCM_SYMBOLP, SCM_ROSTRINGP): No need to distinguish between
305 different symbol types any more.
306
307 (SCM_PROP_SLOTS, SCM_SET_PROP_SLOTS): Added.
308
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.
312
313 * tags.h (scm_tc7_ssymbol, scm_tc7_msymbol, scm_tcs_symbols):
314 Deprecated.

370
371 2000-09-05 Marius Vollmer <mvo@zagadka.ping.de>
372
373 * init.c: Include "libguile/properties.h".

385 * validate.h (SCM_VALIDATE_NUMBER_DEF_COPY): New macro.
386
387 2000-09-03 Marius Vollmer <mvo@zagadka.ping.de>
388
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
392 Koeppe!
393
394 2000-08-27 Marius Vollmer <mvo@zagadka.ping.de>

407 properties.c.
408
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

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'.)
488
489 * stacks.c (scm_init_stacks): Pass a string, not a layout object,
490 to scm_make_vtable_vtable. (Thanks to Dale P. Smith.)
491
492 * struct.c (scm_make_struct_layout): Removed reference to
493 "read-only string" in comment; Check that argument is a string.
494 (scm_make_vtable_vtable): Check that argument is a string.
495
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.)
501
502 * strings.c (scm_make_shared_substring, scm_read_only_string_p):
503 Deprecated.
504 (scm_string_length, scm_string_ref, scm_substring,
505 scm_string_append): Don't accept symbols as arguments (R5RS).
506
507 2000-08-25 Neil Jerram <neil@ossau.uklinux.net>
508
509 * ports.c (scm_set_port_column_x): Fix docstring so that it
510 mentions set-port-line! rather than set-port-column! twice.
511
512 * guardians.c (scm_make_guardian): Remove spurious . from doc string.
513
514 2000-08-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
515
516 * Makefile.am: Added all necessary environments.* files.
517
518 * init.c: Include environments.h.
519
520 (scm_boot_guile_1): Initialize the environments.
521
522 * environments.[ch]: Added. Most of the credit for these files
523 goes to Jost Boekemeier.
524
525 2000-08-25 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
526
527 * procprop.c: #include "libguile/smob.h"; handle applicable smobs.
528
529 2000-08-24 Keisuke Nishida <kxn30@po.cwru.edu>
530
531 * smob.h (scm_smob_descriptor): Added `apply' and `gsubr_type'.
532 * smob.c (scm_make_smob_type): Initialize `apply' and `gsubr_type'.
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.
538
539 2000-08-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
540
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. :)
545
546 * fluids.c (scm_fluid_set_x): Return SCM_UNSPECIFIED.
547
548 2000-08-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
549
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.)
553
554 2000-08-21 Michael Livshin <mlivshin@bigfoot.com>
555
556 * gc.h (SCM_GC_CARD_N_CELLS): change to be a nice non-confusing
557 constant.
558
559 2000-08-19 Michael Livshin <mlivshin@bigfoot.com>
560
561 * gc.c (scm_gc_sweep): added a `continue' statement that have
562 fallen through the cracks in the merge. thanks to Shuji Narazaki!
563
564 * gc.h: removed some stuff that broke compilation for people and
565 wasn't actually needed anyway.
566
567 2000-08-18 Neil Jerram <neil@ossau.uklinux.net>
568
569 * filesys.c (scm_fcntl): Docstring fix - missing newlines inserted.
570
571 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_sethost,
572 scm_setnet, setproto, setserv): Argument names changed to match
573 doc string.
574
575 * feature.c (scm_program_arguments): New docstring.
576
577 * simpos.c (scm_getenv): Reflow docstring.
578
579 * eq.c (scm_eq_p, scm_eqv_p, scm_equal_p): Add texinfo markup to
580 docstrings.
581
582 * chars.c (scm_char*): Docstring fixes - texinfo markup.
583
584 2000-08-18 Neil Jerram <neil@ossau.uklinux.net>
585
586 * boolean.c (scm_not, scm_boolean_p): Docstring fixes - add
587 texinfo markup and remove trailing newlines.
588
589 2000-08-17 Michael Livshin <mlivshin@bigfoot.com>
590
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).
595
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.
599
600 * gc.h (SCM_MARKEDP): simplified, there are no different mark bit
601 locations anymore.
602 (SCM_GC_CARD_*, SCM_C_BVEC_*): lots of new macros to deal with
603 cards and bvecs (bit-vectors).
604
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
609 into account.
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
615 mark phase.
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.
619 (scm_cellp): ditto.
620 (scm_gc_sweep): simplified.
621 (init_heap_seg): changed to take cards into account.
622
623 2000-08-16 Michael Livshin <mlivshin@bigfoot.com>
624
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.
631
632 * stime.h: added prototype for scm_c_get_internal_run_time.
633
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.
645
646 * gc.h: removed prototypes for scm_gc_{start,end}.
647
648 2000-08-13 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
649
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.
653
654 2000-08-13 Neil Jerram <neil@ossau.uklinux.net>
655
656 * root.c (s_scm_call_with_dynamic_root): Docstring fix - rogue
657 newline.
658
659 2000-08-12 Neil Jerram <neil@ossau.uklinux.net>
660
661 * numbers.c (scm_ash): Docstring fix - missing newlines.
662
663 * ports.c (scm_port_filename): Docstring fix - missing newline.
664
665 * strports.c (scm_eval_string): Docstring fix - missing newline.
666
667 * vports.c (s_scm_make_soft_port): Docstring updated so that
668 example is correct.
669
670 * strop.c: Docstring fixes - quotation marks and backslashes
671 needed quoting.
672
673 * numbers.c (s_scm_logand): Docstring fix - "@end lisp" inserted.
674
675 2000-08-11 Neil Jerram <neil@ossau.uklinux.net>
676
677 * macros.c: Remove surplus newlines from end of docstrings.
678
679 * list.c (scm_list_tail): Add @deffnx line to docstring for
680 list-cdr-ref.
681
682 * keywords.c: Docstring improvements in conjunction with new
683 reference manual doc on keywords.
684
685 * error.c (scm_error_scm): Fix texinfo syntax error in
686 docstring. (@code(~S) should be @code{~S}.)
687
688 * dynl.c: Remove surplus newlines from end of docstrings.
689
690 2000-08-11 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
691
692 * eval.c (scm_eval): Backward incompatible change: Now takes an
693 environment specifier as second arg. `eval' hereby becomes R5RS
694 compatible.
695 (scm_i_eval_x, scm_i_eval): New functions (replace
696 scm_eval_3).
697 (scm_eval2, scm_eval_3): Deprecated.
698 (scm_top_level_lookup_closure_var): Deprecated.
699
700 * eval.h: #include "struct.h".

706 SCM_MODULE_OBARRAY, SCM_MODULE_USES, SCM_MODULE_BINDER,
707 SCM_MODULE_EVAL_CLOSURE): New macros.
708 (scm_module_index_obarray, scm_module_index_uses,
709 scm_module_index_binder, scm_module_index_eval_closure): New
710 constants; #include "validate.h".
711
712 * modules.c (scm_module_tag, scm_module_system_booted_p): New
713 globals.
714 (scm_post_boot_init_modules): Initialize scm_module_tag.
715 (scm_interaction_environment): New primitive.
716
717 * symbols.c (scm_can_use_top_level_lookup_closure_var): Removed.
718 #include "modules.h".
719
720 * strports.c (scm_eval_string): Evaluate in
721 scm_interaction_environment ().
722
723 * script.c (scm_shell): Pass scm_the_root_module () as second arg
724 to new scm_eval_x.
725
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".
730
731 * debug.c (scm_local_eval): Use scm_i_eval and scm_i_eval_x.

737 directives.
738
739 2000-08-09 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
740
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.
744
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
748 chain.
749
750 * struct.h (SCM_STRUCT_GC_CHAIN, SCM_SET_STRUCT_GC_CHAIN): New
751 macros.
752 (scm_structs_to_free, scm_struct_prehistory): Declare.
753
754 * struct.c (scm_make_struct, scm_make_vtable_vtable): Structs
755 handles are now double cells; Initialize SCM_STRUCT_GC_CHAIN to
756 0.
757 (scm_struct_gc_init, scm_free_structs): New GC C hooks.
758 (scm_struct_prehistory): Install them.
759
760 * init.c (scm_boot_guile_1): Call scm_struct_prehistory.
761
762 2000-08-06 Marius Vollmer <mvo@zagadka.ping.de>
763
764 * read.c (scm_flush_ws): Include filename in error message when it
765 is not `#f'.
766
767 2000-08-05 Marius Vollmer <mvo@zagadka.ping.de>
768
769 * iselect.c: Include <unistd.h>. Thanks to Bertrand Petit!
770
771 2000-08-02 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
772
773 * struct.c (scm_make_struct_layout, scm_make_struct,
774 scm_make_vtable_vtable): Updated documentation.
775
776 * print.c (scm_simple_format): Bugfix: Coerce port before using
777 it.
778
779 2000-07-31 Gary Houston <ghouston@arglist.com>
780
781 * net_db.c: declare h_errno only if HAVE_H_ERRNO is not defined
782 (thanks to Richard Kim for the bug report).
783
784 2000-07-30 Marius Vollmer <mvo@zagadka.ping.de>
785
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.
789
790 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
791
792 * gc.c (scm_gc_sweep): Renamed local variable from 'free' to
793 'free_struct_data' to avoid confusion with stdlib's 'free'.
794
795 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
796
797 * vectors.c (scm_make_vector): Fix the initialization order of
798 the vector such that the type cell is initialized last.
799
800 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
801
802 * struct.[ch] (scm_struct_init): Made static. Fixed not to rely
803 on the struct cell to be fully initialized.
804
805 * struct.c (scm_make_struct, scm_make_vtable_vtable): Fix the
806 initialization order of the struct such that the type cell is
807 initialized last.
808
809 2000-07-25 Marius Vollmer <mvo@zagadka.ping.de>
810
811 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
812 scm_assoc_remove_x): Remove only the first cell with a matching
813 key, not all.
814
815 2000-07-24 Marius Vollmer <mvo@zagadka.ping.de>
816
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!
820
821 2000-07-23 Marius Vollmer <mvo@zagadka.ping.de>
822
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
827 to Neil Jerram!
828
829 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
830
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.
834
835 * modules.c (scm_standard_eval_closure): Don't pass an inum to
836 scm_makcclo, but rather a long value.
837
838 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
839
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.
843
844 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
845
846 * root.[ch] (scm_call_catching_errors): Deprecated.
847
848 * root.c (scm_init_root): Initialize the root smob type using the
849 standard initialization functions.
850
851 2000-07-17 Marius Vollmer <mvo@zagadka.ping.de>
852
853 * eval.c (unmemocopy): Don't rely on V being a list of at least
854 one element. Thanks to Bill Schottstaedt!
855
856 2000-07-15 Michael Livshin <mlivshin@bigfoot.com>
857
858 * gc.c (scm_done_free): new.
859 expanded comments about scm_done_malloc.
860
861 * gc.h: added prototype for scm_done_free
862
863 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
864
865 * gc.h (scm_take_stdin): Removed.
866
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.
870
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.
874
875 * gc.c (debug_cells_p): Added to indicate whether compile-time
876 included cell access debugging is run-time enabled.
877
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
880 at most places.
881
882 * error.c (scm_error), gdbint.c (SCM_GC_P): Use scm_gc_running_p
883 instead of scm_gc_heap_lock.
884
885 * gc.c (scm_igc): Set scm_gc_running_p to true while running.
886
887 * gc.c (scm_mark_locations): Don't mark free cells.
888
889 * weaks.c (scm_scan_weak_vectors): Use SCM_FREE_CELL_P instead of
890 SCM_FREEP.
891
892 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
893
894 * gc.c (scm_mark_locations): Minimized some variable scopes and
895 simplified the code a bit.
896
897 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
898
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.
906
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.
912
913 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
914
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)
918 should be used.
919
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.
923
924 2000-07-07 Dirk Herrmann <D.Herrmann@tu-bs.de>
925
926 * hashtab.c (scm_hash_fn_create_handle_x): Signal an error if the
927 given hash table has no slots.
928
929 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
930
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.
933
934 (scm_check_freelist): No need to flush streams before abort().
935
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.
939
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.
943
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
947 date.
948
949 (scm_init_storage): Initialize heap_segment_table_size.
950
951 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
952
953 * gh.h: Don't include <stdio.h>. Thanks to Han-Wen Nienhuys for
954 the hint.
955
956 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
957
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
962 symbols.
963
964 * error.c (scm_wta): Re-introduce dispatching for SCM_OUTOFRANGE
965 and SCM_NALLOC, but as a deprecated feature.
966
967 2000-06-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
968
969 * debug.c: Added #include fluids.h.
970
971 * numbers.c (scm_gr_p, scm_leq_p, scm_geq_p): Turned into
972 primitive generics. (Thanks to Nicolas Neuss.)
973
974 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
975
976 * gc.c (alloc_some_heap): Use scm_memory_error to indicate a
977 failed attempt to get additional memory from the system.
978
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
981 cells.
982
983 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
984
985 * __scm.h (SCM_OUTOFRANGE): Removed.
986
987 * error.c (scm_wta): Removed sick dispatch code for range
988 errors. (More sick dispatches still to be removed.)
989
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
993 errors.
994
995 * hooks.c (make_hook), unif.c (scm_aind): Use scm_out_of_range to
996 signal range errors.
997
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.
1002
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
1006 range checks.
1007
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
1010 errors.
1011
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.
1015
1016 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1017
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.
1024
1025 (SCM_ASSERT_RANGE): Use scm_out_of_range to signal range errors.
1026
1027 2000-06-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1028
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.
1033 (Thanks to Dirk.)
1034
1035 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1036
1037 * __scm.h (SCM_NALLOC): Removed.
1038
1039 * error.c (scm_wta): Removed sick dispatch code for memory
1040 errors. (More sick dispatches still to be removed.)
1041
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
1046 memory errors.
1047
1048 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1049
1050 * __scm.h: Removed some commented code and fixed some comments.
1051
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.
1055
1056 * async.c: Removed some commented code.
1057
1058 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1059
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.
1063
1064 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1065
1066 * root.h (scm_first_type): Removed.
1067
1068 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1069
1070 * gc.c (MIN_GC_YIELD): Removed.
1071
1072 2000-06-28 Michael Livshin <mlivshin@bigfoot.com>
1073
1074 * gc.c (scm_gc_for_newcell): don't try to do GC if it's blocked,
1075 allocate instead.
1076
1077 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1078
1079 * async.c (scm_gc_async, scm_gc_vcell, scm_sys_gc_async_thunk):
1080 Moved to gc.c.
1081
1082 (scm_init_async): Moved initialization for scm_gc_async and
1083 scm_gc_vcell to gc.c. Moved initialization of scm_asyncs here
1084 from gc.c.
1085
1086 * async.h (scm_gc_async): Not globally visible any more.
1087
1088 * gc.c (scm_gc_stats): Made callable even from within regions
1089 where gc is blocked.
1090
1091 (scm_gc_end): Eliminate the hardcoding of the marking of the
1092 scm_gc_async from the gc core.
1093
1094 (scm_init_storage): Don't initialize the scm_asyncs list here.
1095 This is now done in asyncs.c.
1096
1097 (scm_gc_vcell): Moved here from async.c.
1098
1099 (gc_async): Renamed from scm_gc_async, moved here from async.c
1100 and made static.
1101
1102 (gc_async_thunk): Renamed from scm_sys_gc_async_thunk and moved
1103 here from async.c.
1104
1105 (mark_gc_async): New hook function for scm_after_gc_c_hook.
1106
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.
1109
1110 * init.c (scm_boot_guile_1): scm_init_gc requires asyncs to be
1111 initialized.
1112
1113 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1114
1115 * gc.c (scm_igc): Removed commented code that once was intended
1116 to unprotect struct types with no instances.
1117
1118 * root.h (scm_type_obj_list): Removed.
1119
1120 2000-06-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
1121
1122 * async.c (scm_init_async): Switch to standard way of smob
1123 initialization.
1124
1125 2000-06-21 Michael Livshin <mlivshin@bigfoot.com>
1126
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
1130 to Brad Knotwell).
1131
1132 2000-06-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
1133
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.
1137
1138 2000-06-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1139
1140 * eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
1141 #include "libguile/fluids.h".
1142
1143 * eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
1144 SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
1145
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".)
1149
1150 * root.c (mark_root): Removed marking of
1151 s->top_level_lookup_closure_var and s->system_transformer.
1152
1153 * modules.c (scm_selected_module): the_module is now a fluid.
1154
1155 2000-06-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1156
1157 * gc.h, tags.h: Be kind to compilers which must see hash signs in
1158 column 0. (Thanks to Ian Grant.)
1159
1160 * numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
1161 the long_long type. (Thanks to Bernard Urban.)
1162
1163 2000-06-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1164
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.)
1173
1174 * list.c (scm_cons_star): Updated comment.
1175
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.
1179
1180 2000-06-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1181
1182 * list.[ch] (scm_cons_star/cons*): Renamed from
1183 scm_list_star/list*.
1184
1185 * list.[ch] (scm_list_star/list*): Provided as a deprecated alias
1186 for scm_cons_star/cons*.
1187
1188 * gc.c (scm_protect_object): Updated comment.
1189
1190 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX): Removed.
1191
1192 * tags.h (SCM_UNPACK_CAR, SCM_NDOUBLE_CELLP): Removed.
1193
1194 2000-06-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1195
1196 * init.c, init.h (scm_initialized_p): Renamed from `initialized'
1197 and made global.
1198
1199 * gdbint.c (gdb_print): Print warning instead of calling scm_write
1200 if Guile isn't yet initialized.
1201
1202 * print.c (scm_current_pstate, scm_make_print_state): Simplified
1203 tests, using the assumption that Guile has been initialized.
1204
1205 Sun Jun 18 14:45:21 2000 Greg J. Badros <gjb@cs.washington.edu>
1206
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().
1210
1211 2000-06-18 Michael Livshin <mlivshin@bigfoot.com>
1212
1213 * scmsigs.c (s_scm_sigaction): guard the SIGIOT case with an
1214 #ifdef -- it's missing on at least one platform. (thanks to
1215 Jan Nieuwenhuizen).
1216
1217 2000-06-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1218
1219 * list.c (list*): Added documentation from common-list.scm.
1220
1221 2000-06-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
1222
1223 * gc.c (scm_unprotect_object): The reference count is guaranteed
1224 to be a positive number.
1225
1226 2000-06-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1227
1228 * eval.c: Updated comment above scm_map.
1229
1230 2000-06-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1231
1232 * gc.c (scm_protect_object): Avoid looking up the object handle
1233 twice.
1234 (scm_unprotect_object): Abort if scm_unprotect_object is called on
1235 an unprotected object.
1236
1237 2000-06-14 Michael Livshin <mlivshin@bigfoot.com>
1238
1239 * gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
1240 Dirk Herrmann).
1241
1242 2000-06-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1243
1244 * socket.c (scm_getsockopt): Changed type for `optlen' from int to
1245 size_t.
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.
1249
1250 * random.c: #include <string.h>. (Needed by memcpy.)
1251
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.
1256
1257 2000-06-14 Gary Houston <ghouston@arglist.com>
1258
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).
1262
1263 2000-06-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1264
1265 * strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
1266
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.)
1269
1270 * Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
1271
1272 2000-06-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1273
1274 * fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
1275 since read and write buffers are allocated by `malloc'.
1276
1277 * Makefile.am: Removed old test code.
1278
1279 * gh_test_c.c, gh_test_repl.c: Removed.
1280
1281 2000-06-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1282
1283 * iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2
1284 compiler.
1285
1286 * inet_aton.c (inet_aton): Cast init value for `cp'.
1287
1288 * ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
1289 `scm_tc7_uvect'.
1290
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.
1294
1295 * strports.c (st_resize_port): Substituted SCM_UCHARS for
1296 SCM_CHARS.
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
1300 ptr.
1301
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.
1305
1306 * ioext.c (s_scm_read_line): Cast result of call to
1307 scm_do_read_line to unsigned char ptr.
1308
1309 * gdbint.c (SEND_STRING): Cast argument to char pointer.
1310
1311 * fports.c (fport_flush): Declare `ptr' as unsigned char (was
1312 char).
1313
1314 * Makefile.am (DOT_DOC_FILES): List doc-files explicitly. (We
1315 shouldn't use Make rules which aren't supported by most Make
1316 programs.)
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.
1323
1324 * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
1325 (The preprocessor might insert spaces before the identifier.)
1326
1327 * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
1328 Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
1329
1330 * smob.h (scm_smobfuns): Removed deprecated type.
1331
1332 * smob.c, smob.h (scm_newsmob): Removed deprecated function.
1333 (Replaced by `scm_make_smob_type'.)
1334
1335 * keywords.c (scm_tc16_kw): Removed deprecated type.
1336 (Replaced by scm_tc16_keyword.)
1337
1338 * kw.h: Removed deprecated header file.
1339
1340 * evalext.c (serial-map): Removed deprected alias for scm_map.
1341 (Has been replaced by `map-in-order'.)
1342
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'.)
1346
1347 2000-06-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1348
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.)
1353
1354 2000-06-10 Michael Livshin <mlivshin@bigfoot.com>
1355
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...).
1361
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.
1364
1365 2000-06-08 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1366
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.)
1370
1371 2000-06-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1372
1373 * modules.c (scm_system_module_env_p): Fixed detection of system
1374 modules.
1375
1376 2000-06-06 Marius Vollmer <mvo@zagadka.ping.de>
1377
1378 * scmsigs.c (scm_sigaction): Silently ignore setting handlers for
1379 `program error signals' because they can't currently be handled by
1380 Scheme code.
1381
1382 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1383
1384 * procs.h (SCM_SET_SUBRF): Added.
1385
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
1388 report.
1389
1390 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1391
1392 * gc.h (SCM_CARLOC, SCM_CDRLOC): Don't take the address of a SCM
1393 value.
1394
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.
1398
1399 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1400
1401 * boolean.h (SCM_TRUE_P): Removed, as people might use it as a
1402 replacement for !SCM_FALSEP.
1403
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).
1415
1416 2000-06-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1417
1418 * eval.c (scm_badformalsp): New static function.
1419 (SCM_CEVAL): Check arguments for procedure-with-setter closures.
1420 (Thanks to Keisuke Nishida.)
1421
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
1425 code.
1426
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...
1431
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
1434 into 1.4.
1435
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.
1443
1444 * modules.h (scm_standard_eval_closure): Declare.
1445
1446 * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
1447 instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
1448
1449 * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
1450 standard eval closures.
1451
1452 * variable.c: Code layout fixes.
1453
1454 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1455
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.)
1459
1460 2000-06-03 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1461
1462 * scmsigs.c (scm_segfault): Removed. (Was probably added by
1463 mistake since it is not mentioned in ChangeLog.)
1464
1465 * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
1466 avoid compiler warnings in gcc. (Does this work for other
1467 compilers?)
1468
1469 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1470
1471 * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
1472 abort ().
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.)
1477
1478 * dynl.c: Changed #include <ltdl.h> --> #include
1479 "libltdl/ltdl.h". (Thanks to Bill Schottstaedt.)
1480
1481 2000-06-01 Craig Brozefsky <craig@red-bean.com>
1482
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.
1487
1488 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1489
1490 * numbers.h (SCM_BIGP): Don't use SCM_SMOB_PREDICATE in header
1491 file: Code using numbers should not be required to include
1492 smob.h.
1493
1494 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1495
1496 * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
1497 mit-pthreads.c, mit-pthreads.h: Deleted.
1498
1499 * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]: Drop
1500 references to deleted files and fsu/mit thread support in
1501 general.
1502
1503 2000-05-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1504
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.
1508
1509 * gc.c (scm_init_gc): We can still rely on scm_create_hook to
1510 protect the object.
1511
1512 2000-05-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
1513
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.
1516
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.
1524
1525 * hooks.h (scm_free_hook): Removed, as it is never defined.
1526
1527 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1528
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
1532 some time, though.
1533
1534 * numbers.c (scm_big2inum): Eliminated use of SCM_UNEGFIXABLE.
1535
1536 * tags.h (SCM_UNPACK_CAR): Deprecated.
1537
1538 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1539
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.
1546
1547 * gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
1548 init_heap_seg): Remove unused struct member variable 'valid'.
1549
1550 2000-05-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
1551
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
1557 appropriately.
1558
1559 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1560
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.
1565
1566 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1567
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.
1570
1571 * eval.c (scm_force): Add documentation.
1572
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.
1575
1576 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1577
1578 * strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
1579 (SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP): Deprecated.
1580
1581 * gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT): Removed #ifdef
1582 nosve #endif conditionally compiled code.
1583
1584 2000-05-23 Michael Livshin <mlivshin@bigfoot.com>
1585
1586 * gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
1587
1588 2000-05-22 Michael Livshin <mlivshin@bigfoot.com>
1589
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.)
1597
1598 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
1599 the previous change to this macros, after deciding to torture the
1600 snarfer instead.
1601
1602 2000-05-21 Michael Livshin <mlivshin@bigfoot.com>
1603
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
1608 scheme.
1609
1610 * init.c (scm_boot_guile_1): removed the code conditioned on
1611 !GUILE_NEW_GC_SCHEME.
1612
1613 * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
1614
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
1620 scheme.
1621
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.
1626
1627 2000-05-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1628
1629 * unif.c (scm_bit_count): Fixed the parameter checks. Thanks to
1630 Dale P. Smith.
1631
1632 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1633
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.
1637
1638 * gc.h (SCM_VALIDATE_CELL): Added. Only performs validation if
1639 SCM_DEBUG_CELL_ACCESSES is set to 1.
1640
1641 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
1642 SCM_SET_CELL_OBJECT): Use SCM_VALIDATE_CELL to check every cell
1643 that is accessed.
1644
1645 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1646
1647 * gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs,
1648 gh_scm2floats, gh_scm2doubles): Change !SCM_NIMP to SCM_IMP.
1649
1650 * gc.c (scm_cellp): Fixed and simplified.
1651
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.
1655
1656 (freejb): Removed.
1657
1658 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1659
1660 * gh.h gh_data.c gh_funcs.c (gh_new_procedure*, gh_chars2byvect,
1661 gh_shorts2svect, gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect,
1662 gh_doubles2dvect, gh_doubles2scm, gh_define, gh_lookup,
1663 gh_module_lookup): Accept const pointers as parameters.
1664
1665 * gh.h gh_data.c (gh_int2scmb): Deprecated.
1666
1667 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1668
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.
1673
1674 * validate.h (SCM_VALIDATE_REST_ARGUMENT): Added.
1675
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.
1682
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.
1687
1688 * filesys.c (scm_fcntl): Made single optional rest argument into
1689 a standard optional argument.
1690
1691 * hooks.c (scm_run_hook): A list of rest arguments is never
1692 SCM_UNBNDP.
1693
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.
1698
1699 * ports.c (scm_close_all_ports_except): Accept empty list of rest
1700 arguments.
1701
1702 * posix.c (scm_convert_exec_args), print.c (scm_simple_format):
1703 Simplify verification of rest argument.
1704
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.
1708
1709 * unif.c (scm_transpose_array, scm_enclose_array,
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.
1713
1714 2000-05-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
1715
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.
1719
1720 * eval.c (scm_map, scm_for_each): Make sure all lists have the
1721 same length. Also, removed redundant parameter checks.
1722
1723 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1724
1725 * Makefile.am: Let 'make clean' remove *.x and *.doc files.
1726
1727 * __scm.h: Improved explanation of giving options to make.
1728
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.
1733
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.
1737
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.
1741
1742 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1743
1744 * numbers.c (scm_logcount, scm_integer_length): Reordered
1745 dispatch sequence.
1746
1747 2000-05-15 Gary Houston <ghouston@arglist.com>
1748
1749 * stime.c (scm_strftime): don't reset TZ if zone is an empty
1750 string. append a "0" to the zone for TZ.
1751
1752 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
1753
1754 * numbers.c (scm_logbit_p, scm_bit_extract): Reordered dispatch
1755 sequence.
1756
1757 (scm_bit_extract): Fixed handling of bignums.
1758
1759 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
1760
1761 * async.c (scm_sys_gc_async_thunk), chars.h (SCM_ICHRP, SCM_ICHR,
1762 SCM_MAKICHR), continuations.h (SCM_SETJMPBUF), error.c
1763 (scm_sysmissing), error.h (scm_sysmissing), evalext.c
1764 ('serial-map), ioext.c (scm_fseek), ioext.h (scm_fseek),
1765 keywords.c (scm_tc16_kw, scm_init_keywords), ports.h (SCM_CRDY,
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.
1771
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.
1777
1778 2000-05-14 Gary Houston <ghouston@arglist.com>
1779
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.
1783
1784 from Keisuke Nishida:
1785 * fports.c (scm_setvbuf): minor docstring fix.
1786 * ports.h (scm_generic_fgets): obsolete prototype deleted.
1787
1788 2000-05-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
1789
1790 * __scm.h: Added new section for debugging options.
1791
1792 (SCM_DEBUG_DEPRECATED): If 1, no deprecated code is included to
1793 help developers to get rid of references to deprecated code.
1794
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
1798 header file.
1799
1800 * numbers.c (scm_make_real, scm_make_complex): Inlined the
1801 corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
1802 respectively.
1803
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.
1807
1808 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1809
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.
1814
1815 (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
1816 Use SCM_SETC[AD]R to modify contents of pairs.
1817
1818 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1819
1820 * numbers.c (IS_INF, isfinite): Added FIXME comment.
1821
1822 (scm_abs, scm_magnitude): Make these two independent of each
1823 other. scm_abs now reports an error if given a complex argument.
1824
1825 (scm_istr2flo, scm_integer_p). Use SCM_REAL_VALUE instead of
1826 SCM_REALPART if the object is known to be real.
1827
1828 (scm_init_numbers): No need to use SCM_NEWREAL macro for speed
1829 here.
1830
1831 * numbers.h (SCM_SINGP): Set to 0 instead of SCM_BOOL_F.
1832
1833 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1834
1835 * eq.c (scm_eqv_p): Separate handling of real and complex
1836 values. Remove #ifdef SCM_BIGDIG #endif test.
1837
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
1845 SCM_INEXP.
1846
1847 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1848
1849 * numbers.c: No need to include unif.h.
1850
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.
1854
1855 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1856
1857 * numbers.c (scm_divbigdig): Removed outdated comment.
1858
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.
1863
1864 (add1, scm_init_numbers): Removed add1.
1865
1866 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1867
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
1870 and Ivan Toshkov.
1871
1872 (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
1873 scm_num2long, scm_num2long_long, scm_num2ulong): Reordered
1874 dispatch sequence.
1875
1876 2000-05-09 Marius Vollmer <mvo@zagadka.ping.de>
1877
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.
1881
1882 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1883
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.
1887
1888 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1889
1890 * feature.c: No need to include "libguile/smob.h"
1891
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.
1897
1898 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1899
1900 * alist.c (scm_acons): Use SCM{_SET}?_CELL_OBJECT as long as a
1901 cell is not known to be a valid pair.
1902
1903 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1904
1905 * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1): Removed
1906 ASRTSYNTAX. Using SCM_ASSYNT instead.
1907
1908 (scm_m_body): Don't create a redundant cons cell.
1909
1910 (scm_m_do): Removed redundant test 'bodycheck'.
1911
1912 (bodycheck): Removed.
1913
1914 * stacks.c (stack_depth, read_frame, read_frames): Removed
1915 redundant calculation of size, minimized some variable scopes.
1916
1917 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1918
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.
1921
1922 (scm_pair_p): Eliminated redundant SCM_IMP test.
1923
1924 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1925
1926 * eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,
1927 scm_deval_args): Eliminated redundant SCM_IMP tests.
1928
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.
1933
1934 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1935
1936 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
1937 Fixed some goto-related initialization bugs (introduced by me).
1938
1939 2000-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
1940
1941 * numbers.h (SCM_INUM0): Uses SCM_MAKINUM instead of SCM_PACK.
1942
1943 * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj): Removed.
1944
1945 (DYNL_FILENAME, DYNL_HANDLE): Use SCM_CELL... macros instead of
1946 pointer trickery.
1947
1948 (SET_DYNL_HANDLE): Added.
1949
1950 (scm_dynamic_object_p): Simplified.
1951
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.
1955
1956 2000-05-03 Marius Vollmer <mvo@zagadka.ping.de>
1957
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!
1961
1962 2000-05-03 Dirk Herrmann <D.Herrmann@tu-bs.de>
1963
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
1971 get alarmed.
1972
1973 * numbers.c: Removed #ifdef SCM_BIGDIG #endif in those functions,
1974 that already have a clean dispatch order. Note: SCM_BIGDIG is
1975 always defined.
1976
1977 * numbers.c (scm_inexact_p): Simplified.
1978
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
1982 integer constants.
1983
1984 * numbers.c (scm_divide): Division by zero of inums leads to an
1985 error now. (Formerly, an infinite number was returned.)
1986
1987 Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
1988 if a division has a remainder.
1989
1990 2000-05-02 Gary Houston <ghouston@arglist.com>
1991
1992 * Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).
1993
1994 2000-05-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
1995
1996 * numbers.c (scm_logtest, scm_division): Reordered dispatch
1997 sequence, thereby fixing some comparisons of SCM values with
1998 integer constants.
1999
2000 * numbers.h (scm_makdbl): Mark as deprecated at the point of
2001 declaration.
2002
2003 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_double2scm,
2004 gh_doubles2scm), numbers.c (scm_istr2flo, scm_max, scm_min,
2005 scm_sum, scm_difference, scm_product, scm_divide, scm_sys_expt,
2006 scm_sys_atan2, scm_make_rectangular, scm_make_polar,
2007 scm_real_part, scm_imag_part, scm_magnitude, scm_angle,
2008 scm_long2num, scm_long_long2num, scm_ulong2num), ramap.c
2009 (ramap_rp, scm_array_map_x), random.c (scm_random,
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
2014 to be zero.
2015
2016 2000-05-01 Gary Houston <ghouston@arglist.com>
2017
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).
2021
2022 * Makefile.am: remove include_HEADERS (was libguile.h)
2023 libguile.h: moved to top level directory.
2024
2025 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2026
2027 * numbers.c (SCM_SWAP): Moved to the top of the file to allow for
2028 a wider use.
2029
2030 * numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,
2031 scm_logxor): Reordered dispatch sequence, thereby fixing some
2032 comparisons of SCM values with integer constants.
2033
2034 * number.c (scm_logtest): Removed some redundant SCM_{N}?IMP
2035 tests.
2036
2037 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2038
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.
2042
2043 * numbers.c (scm_quotient): Fixed parameter number in error
2044 message.
2045
2046 * numbers.c (scm_remainder): Reordered dispatch sequence.
2047
2048 2000-04-25 Gary Houston <ghouston@arglist.com>
2049
2050 * posix.c (scm_execlp): docstring fix (thanks to Martin
2051 Grabmueller).
2052
2053 2000-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2054
2055 * eval.c (undef_object): Made into a local static variable
2056 (suggested by Jost Boekemeier).
2057
2058 2000-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2059
2060 * pairs.c (cxrs, scm_init_pairs): Simplify initialization of
2061 c[ad]+r functions.
2062

2064 scm_dsubr, scm_init_iprocs): Removed.
2065
2066 * procs.h (SCM_SUBRF, SCM_DSUBRF): Access the cell words
2067 directly instead of casting a cell to a C struct.
2068
2069 2000-04-22 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2070
2071 Better modularization of GC extensions through new C level GC
2072 hooks:
2073
2074 * weaks.c (scm_weaks_prehistory): New function: Add
2075 scm_weak_vector_gc_init to scm_before_mark_c_hook; Add
2076 scm_mark_weak_vector_spines to scm_before_sweep_c_hook.
2077 (scm_scan_weak_vectors): New function; added to
2078 scm_after_sweep_c_hook.
2079
2080 * weaks.h (scm_weak_vectors, scm_weaks_prehistory): Added
2081 declarations.
2082
2083 * guardians.h (scm_guardian_gc_init, scm_guardian_zombify): Are
2084 now static.
2085
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.
2090
2091 * async.c (scm_sys_gc_async_thunk): Run after-gc-hook.
2092 Added #include "libguile/gc.h".
2093
2094 * gc.h: Added #include "libguile/hooks.h".
2095
2096 * gc.c: Removed #include "libguile/guardians.h".
2097 (scm_before_gc_c_hook, scm_before_mark_c_hook,
2098 scm_before_sweep_c_hook, scm_after_sweep_c_hook,
2099 scm_after_gc_c_hook): New C level hooks.
2100 (scm_after_gc_hook): New Scheme level hook.
2101 (scm_gc_sweep): Moved scanning of weak vectors to weaks.c.
2102 (scm_igc): Moved initialization of scm_weak_vectors and the call
2103 to scm_guardian_gc_init to respective module.
2104 (scm_mark_weak_vector_spines): Moved to weaks.c;
2105 Call to scm_guardian_zombify moved to guardians.c;
2106 Run scm_before_gc_c_hook, scm_before_sweep_c_hook,
2107 scm_after_gc_c_hook at appropriate places.
2108 (scm_init_gc): Initialize scm_after_gc_hook.
2109
2110 * hooks.c, hooks.h (scm_make_hook_with_name): Removed deprecated
2111 function.
2112
2113 * init.c (scm_boot_guile_1): Added `scm_init_hooks'.
2114
2115 * Makefile.am: Added hooks.c, hooks.h, hooks.x.
2116
2117 * feature.c, feature.h: Broke out hook code into separate files.
2118
2119 * hooks.c, hooks.h: New files.
2120
2121 * *.*: Change includes so that they always use the "prefixes"
2122 libguile/, qt/, guile-readline/, or libltdl/.
2123 (Thanks to Tim Mooney.)
2124
2125 * Makefile.am (INCLUDES): Removed THREAD_CPPFLAGS and INCLTDL.
2126 (DEFS): Added. automake adds -I options to DEFS, and we don't
2127 want that.
2128 Removed all -I options except for the root source directory and
2129 the root build directory.
2130
2131 * numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG
2132 instead of SCM_ASSERT (0, ...). (Some compilers will complain
2133 about control reaching end of function otherwise, and, besides,
2134 the new code is not less clear.)
2135
2136 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Added
2137 calls to malloc debugging functions.
2138

2148
2149 * numbers.c (scm_exact_p, scm_odd_p, scm_even_p): Added
2150 documentation strings.
2151
2152 * numbers.c (scm_exact_p, scm_odd_p, scm_even_p, scm_abs,
2153 scm_quotient): Reordered dispatch sequence to first handle
2154 immediates, second handle bignums and finally handle generic
2155 functions respectively signal wrong type arguments. Hopefully
2156 this will allow for easier separation when goops is integrated.
2157
2158 2000-04-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
2159
2160 * gc.c (which_seg): Use SCM2PTR to convert a non immediate SCM

2164 scm_unhash_name): Remove redundant cast to SCM_CELLPTR.
2165

2168 * print.c (scm_iprin1): Don't assign zero to SCM values, use
2169 SCM_UNDEFINED instead.
2170
2171 * weaks.c (scm_make_weak_vector): Fix assignment of zero to a
2172 vector element. (Still to be improved)
2173
2174 2000-04-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
2175
2176 * eval.c (undef_cell): Removed, replaced by:
2177
2178 (undef_object): Added to replace undef_cell.
2179
2180 (scm_lookupcar, scm_lookupcar1): Use undef_object.
2181
2182 * eval.c (scm_lookupcar, scm_lookupcar1, scm_m_atfop,
2183 scm_m_atbind, CHECK_EQVISH, SCM_CEVAL), procs.h (SCM_SETCODE):
2184 Don't perform arithmetic operations with SCM values.
2185
2186 * eval.c (scm_lookupcar, scm_lookupcar1, scm_m_atfop,
2187 scm_m_atbind, scm_eval_args, scm_deval_args, SCM_CEVAL): Use
2188 symbolic names for the tc3 type codes.
2189
2190 * eval.c (scm_m_define, SCM_CEVAL, SCM_APPLY): Remove redundant
2191 cast to SCM.
2192
2193 * eval.c (scm_eval_args, scm_deval_args, SCM_CEVAL): Made the
2194 access of the struct vcell element explicit.
2195
2196 2000-04-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2197
2198 * struct.c (scm_struct_free_light, scm_struct_free_standard,
2199 scm_struct_free_entity): Use `scm_must_free' instead of `free'.
2200
2201 * procs.c (scm_make_subr_opt): Tell scm_must_realloc that we're
2202 realloc:ing scm_subr_table ("what" instead of "who").
2203
2204 * numbers.c (scm_adjbig): Ditto.
2205
2206 Tue Apr 18 08:22:41 2000 Greg J. Badros <gjb@cs.washington.edu>
2207
2208 * validate.h: Do not cast to (unsigned) in SCM_VALIDATE_INUM_RANGE
2209 when testing high-end of the range. Mikael Djurfeldt noticed this
2210 anomaly -- thanks Mikael!
2211
2212 2000-04-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
2213
2214 * unif.c (l2ra): Don't eliminate the call to scm_array_set_x
2215 itself, as was done in the previous 'patch'. (Thanks to Radey
2216 Shouman)
2217
2218 2000-04-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
2219
2220 * options.c (scm_options), read.c (recsexpr): Remove redundant
2221 SCM_IMP test.
2222
2223 * print.c (scm_iprin1): Made the access of the struct vcell
2224 element explicit.
2225
2226 * print.h (SCM_PRINT_CLOSURE): Added call to SCM_PACK.
2227
2228 * ramap.c (scm_ra_eqp, ra_compare), unif.c
2229 (scm_uniform_vector_ref, scm_cvref, rapr1): Separated accesses to
2230 unsigned long and signed long arrays and clarified the way the
2231 access is performed.
2232
2233 * ramap.c (scm_array_map_x, raeql), read.c (scm_lreadr), stacks.c
2234 (narrow_stack), unif.c (scm_cvref, scm_uniform_array_read_x,
2235 scm_raprin1): Use SCM_EQ_P to compare SCM values.
2236
2237 * strings.c (scm_makstr): Treat the msymbol slots as a field of
2238 scm_bits_t values.
2239
2240 * struct.h (SCM_SET_VTABLE_DESTRUCTOR): Treat the struct data as
2241 a field of scm_bits_t values.
2242
2243 * unif.c (l2ra): Don't test result of scm_array_set_x against
2244 zero: It is always SCM_UNSPECIFIED.
2245
2246 2000-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2247
2248 * script.c (scm_compile_shell_switches): Also enable
2249 record-positions when given the --debug option. (Thanks to Diego
2250 Dainese.)
2251
2252 2000-04-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
2253
2254 * print.c (ENTER_NESTED_DATA, print_circref, scm_iprlist):

2444
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

2449 * async.c: reflect the fact that asyncs are now represented by
2450 single heap cell each.

2515
2516 * guardians.c (scm_guardian_zombify): mark all zombies in a
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).

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
2666 major structure.
2667
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.
2674
2675 * coop-defs.h (struct coop_t): Removed dummy_mutex.
2676
2677 * coop-defs.h, coop-threads.c (struct coop_t): Eliminate
2678 `sto'-field when GUILE_PTHREAD_COMPAT is enabled.
2679
2680 2000-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
2681
2682 * arbiters.c (scm_make_arbiter), async.c (scm_async), dynwind.c
2683 (scm_internal_dynamic_wind): Smob data is always of type
2684 scm_bits_t.
2685
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.
2689
2690 * async.c (scm_run_asyncs): Use SCM_NULLP to test for the empty
2691 list.
2692
2693 * dynwind.c (scm_dowinds): Use SCM_EQ_P to compare SCM values.
2694
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.
2697
2698 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2699
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
2704 SCM_EQ_P instead.
2705
2706 * boolean.c (scm_boolean_p): Use SCM_BOOLP to determine whether a
2707 SCM value is equal to #t or #f.
2708
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.
2712
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
2717 #t.
2718
2719 * list.c (scm_listify): Use SCM_UNBNDP to test for an unbound
2720 scheme value.
2721
2722 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2723
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.
2727
2728 * coop.c (coop_create): Set `specific' field, not `data' to NULL.
2729
2730 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2731
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].
2735
2736 Note that this implies that smob data has always to be passed as
2737 values of type scm_bits_t.
2738
2739 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2740
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.
2744
2745 * error.c (scm_error): Don't try to throw an error if
2746 scm_gc_heap_lock is true.
2747
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.
2752
2753 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread):
2754 Changed SETCDR --> SET_CELL_WORD_1.
2755
2756 * coop-threads.c (scheme_launch_thread): Set word 1 of handle to 0
2757 when thread dies.
2758
2759 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2760
2761 * boolean.h (SCM_TRUE_P): New macro.
2762
2763 * boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP), pairs.h
2764 (SCM_NULLP, SCM_NNULLP): Use SCM_EQ_P to compare SCM values.
2765
2766 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2767
2768 * continuations.h (SCM_CONTREGS, SCM_SET_CONTREGS): New macros to
2769 access continuation data.
2770
2771 (SCM_SETJMPBUF): Deprecated. Use SCM_SET_CONTREGS instead.
2772
2773 (SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE, SCM_BASE, SCM_SEQ,
2774 SCM_DFRAME): Use SCM_CONTREGS instead of SCM_CHARS to access
2775 continuation data.
2776
2777 * continuations.c (scm_make_cont), init.c (start_stack),
2778 root.c (scm_internal_cwdr): Use SCM_SET_CONTREGS instead of
2779 SCM_SETJMPBUF.
2780
2781 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2782
2783 * symbols.h (SCM_LENGTH, SCM_SETLENGTH): Access the length field
2784 of strings and symbols by using SCM_{SET_}?CELL_WORD_0.
2785
2786 (SCM_CHARS, SCM_UCHARS, SCM_SETCHARS): Use SCM_{SET_}?CELL_WORD_1
2787 to access the char * field of strings and symbols.
2788
2789 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2790
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.
2794
2795 (SCM_FREEP, SCM_MARKEDP): Use SCM_CELL_TYPE to access the type
2796 entry of a cell.
2797
2798 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2799
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.
2804
2805 (SCM_GCCDR): Moved to tags.h.
2806
2807 * tags.h (SCM_GCCDR): Moved here from pairs.h.
2808
2809 2000-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
2810
2811 * tags.h (SCM2PTR, PTR2SCM): Moved to gc.h.
2812
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.
2818
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.
2822
2823 (SCMPTR): Deleted.
2824
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
2831 tags.h and pairs.h.
2832
2833 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2834
2835 * tags.h (SCM_STRICT_TYPING): New macro that, if defined,
2836 activates strict compile time type checking for variables of
2837 type SCM.
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?.
2841
2842 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2843
2844 * tags.h (SCM_POINTERS_MUNGED): Removed.
2845
2846 * gc.c (scm_gc_sweep, init_heap_seg): Removed use of
2847 SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
2848
2849 2000-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
2850
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
2854 cell entries.
2855 (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
2856
2857 * procs.h, procs.c: Instead of SCM_{SET_}?CELL_WORD[12], use the
2858 newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
2859
2860 2000-03-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2861
2862 * tags.h: Disabled definition of SCM_VOIDP_TEST.
2863
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.
2867
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.
2871
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.
2875
2876 * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
2877
2878 * continuations.c (scm_make_cont): Removed cast of size_t into
2879 long.
2880
2881 * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
2882
2883 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2884
2885 * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for
2886 shifting, not constant. Thanks to Dale P. Smith.
2887
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,
2890 thank you Dale.
2891
2892 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2893
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.
2897
2898 2000-03-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2899
2900 * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
2901 pointer-arithmetic induced by the SCM_PACK/UNPACK change.
2902
2903 * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
2904
2905 * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
2906
2907 * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
2908
2909 * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
2910
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.
2916
2917 2000-03-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2918
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.
2925
2926 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2927
2928 * struct.h (SCM_STRUCT_DATA): Don't cast SCM values to pointers.
2929
2930 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2931
2932 * symbols.h, symbols.c (scm_strhash): Declare the string
2933 parameter as constant, since it is not modified.
2934
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.
2938
2939 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2940
2941 * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS): Don't cast SCM
2942 values to pointers. Use SCM2PTR instead.
2943
2944 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2945
2946 * async.c (scm_set_tick_rate, scm_set_switch_rate): Don't unpack
2947 results of SCM_INUM.
2948
2949 2000-03-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2950
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.
2954
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.
2959
2960 * gc.c (alloc_some_heap): Further improvement of minimal heap size
2961 prediction.
2962 (SCM_MAX): New macro.
2963 (scm_freelist_t): New field: collected_1. Previous amount of
2964 collected cells.
2965 (gc_sweep_freelist_finish): Trigger based on two last values of
2966 freelist->collected to avoid unnecessary allocation due to
2967 temporary peaks.
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.
2971
2972 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2973
2974 * numbers.h (SCM_MAKINUM): The parameter to SCM_MAKINUM should
2975 already be a C value. No need to unpack it.
2976
2977 * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t
2978 if we know it fits into an inum.
2979
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
2982 SCM values.
2983
2984 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2985
2986 * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
2987 etc.
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
2991 gc_trigger.
2992
2993 * print.h, stacks.h, options.c, options.h: Changed C++
2994 commentaries to C.
2995
2996 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2997
2998 * tags.h (SCM2PTR, PTR2SCM): Use SCM_PACK / SCM_UNPACK correctly.
2999
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.
3003
3004 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3005
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.
3010
3011 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
3012
3013 * eval.h: Fix mixup of packed/unpacked SCM values. (Thanks
3014 Thien-Thi Nguyen for the patch.)
3015
3016 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
3017
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.)
3021
3022 2000-03-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3023
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.
3028
3029 * coop-threads.c: Addd #include "root.h", #include "strings.h".
3030
3031 * debug.c: Added #include "root.h". (Thanks to Thien-Thi Nguyen.)
3032
3033 * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
3034 trigger adjustmeant: Take yield (freed cells) for all freelists
3035 into account.
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'.
3045
3046 2000-03-19 Michael Livshin <mlivshin@bigfoot.com>
3047
3048 * *.[hc]: add Emacs magic at the end of file, to ensure GNU
3049 indentation style.
3050
3051 2000-03-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3052
3053 * threads.h: Added #include "libguile/throw.h". (Thanks to
3054 Thien-Thi Nguyen.)
3055
3056 2000-03-18 Michael Livshin <mlivshin@bigfoot.com>
3057
3058 * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
3059 names, anyone got any better ones?)
3060
3061 * gc.h: (typedef struct scm_freelist_t) remove from here.
3062
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.
3077
3078 2000-03-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
3079
3080 * _scm.h: Don't include async.h everywhere...
3081
3082 * eq.c eval.c iselect.c: ... only include it here.
3083
3084 2000-03-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
3085
3086 * _scm.h: Don't include root.h everywhere...

3135 2000-03-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3136
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.
3142
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
3147
3148 2000-03-16 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3149
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.
3155
3156 2000-03-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3157
3158 * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
3159 defined.
3160 (scm_free_list_length): New procedure (GUILE_DEBUG).
3161 Fixed a small but serious bug introduced by the previous change.
3162
3163 * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
3164 loop and declare as register.
3165
3166 * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
3167 after GC.
3168
3169 Wed Mar 15 08:27:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3170
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?
3174
3175 Wed Mar 15 08:24:58 2000 Greg J. Badros <gjb@cs.washington.edu>
3176
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.
3181
3182 Wed Mar 15 08:12:14 2000 Greg J. Badros <gjb@cs.washington.edu>
3183
3184 * libguile.h: Include libguile/validate.h. Thanks Keisuke Nishida!
3185
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.
3189
3190 2000-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3191
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
3194 contains bugs.
3195
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.
3202
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.
3205
3206 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3207
3208 The following change to init.c is only enabled if Guile was
3209 configured with --enable-guile-debug.
3210
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
3215 the future.)
3216
3217 * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
3218 scm_assoc. (Thanks to Keisuke Nishida.)
3219
3220 2000-03-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3221
3222 * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
3223 scm_nil, scm_t. (Thanks to Keisuke Nishida.)
3224
3225 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3226
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.)
3233
3234 [Almost all of these changes should be documented in the NEWS
3235 file.]
3236
3237 * gc.h (scm_freelist_t): New type.
3238
3239 * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
3240
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
3243 for work.
3244 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
3245 instead of 2.
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
3249 list.
3250 (scm_heap_size, scm_gc_cells_collected): Removed.
3251
3252 * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
3253
3254 * Makefile.am (libguile_la_LDFLAGS): Bumped library version
3255 number.
3256
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
3262 still supported.)
3263
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.
3269
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.
3274 (SCM_FLO): Removed.
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.
3283 (scm_dbl): Removed.
3284
3285 * numbers.c (scm_floprint, scm_floequal): Removed.
3286 (scm_print_real, scm_print_complex, scm_real_equalp,
3287 scm_complex_equalp): New functions.
3288
3289 * unif.c (scm_makflo): Removed.
3290
3291 * smob.h (SCM_SMOB_PREDICATE): New macro.
3292 (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
3293 SCM_RETURN_NEWSMOB3): New macros.
3294
3295 1999-11-21 Michael Livshin <mlivshin@bigfoot.com>
3296
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
3300 modified by mdj.)
3301
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
3306 macros.
3307
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
3314 more than one.
3315 (scm_debug_newcell2): multi-cell variants of
3316 scm_debug_newcell.
3317 (scm_gc_for_newcell): take ncells and freelist pointer as
3318 parameters.
3319 (scm_gc_mark): add case for tc7_pws (procedures with setters are
3320 now double cells).
3321 (scm_gc_sweep): don't free the float data, since it's not malloced
3322 anymore.
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}.
3328
3329 * numbers.c (scm_makdbl): no malloc'ing needed, so the
3330 {DEFER,ALLOW}_INTS thing removed.
3331
3332 * numbers.h (struct scm_dbl): changed to represent a double cell,
3333 with the number in the second half.
3334
3335 * dynwind.c: changed the wind-guards representation to double
3336 cell.
3337
3338 * procs.c, procs.h: changed the procedure-with-setter representation
3339 to double cell.
3340
3341 * async.c, async.h: made async representation a double cell.
3342
3343 * dynl.c: made dynamic_obj representation a double cell.
3344
3345 2000-03-13 Gary Houston <ghouston@arglist.com>
3346
3347 * ports.c (flush_void_port): renamed to flush_port_default.
3348 (end_input_void_port): renamed to end_input_default.
3349
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).
3354
3355 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
3356
3357 * void ports: make reading from a void port give EOF instead of
3358 segv:
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.
3364
3365 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
3366 which was incorrectly appended.
3367
3368 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3369
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
3373 Herrman.)
3374
3375 2000-03-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3376
3377 * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
3378 EXTRA_libguile_la_SOURCES.
3379
3380 * iselect.h: Always declare scm_internal_select.
3381
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
3384 not using threads.
3385
3386 * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
3387
3388 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3389
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?)
3393
3394 Sun Mar 12 13:26:30 2000 Greg J. Badros <gjb@cs.washington.edu>
3395
3396 * Makefile.am: Added *.doc to DISTCLEANFILES.
3397
3398 2000-03-12 Gary Houston <ghouston@arglist.com>
3399
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.
3405
3406 * throw.c: change an outdated comment about scm_internal_catch
3407 BODY: it doesn't take a jumpbuf arg.
3408
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.
3416
3417 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3418
3419 * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
3420 Renamed from SCMWORD.
3421
3422 * tags.h (SCM_NCELLP): Removed (SCMWORD).
3423
3424 * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
3425
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,
3428 hash.c, keywords.h, macros.c, numbers.c, numbers.h, objects.c,
3429 objects.h, options.c, pairs.h, ports.c, ports.h, print.c,
3430 procs.h, ramap.c, read.c, smob.c, smob.h, srcprop.h, stacks.c,
3431 stacks.h, strports.c, struct.c, struct.h, tag.c, tags.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).
3435
3436 * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
3437
3438 * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
3439 tags.h: Fixed copyright notices.
3440
3441 * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
3442
3443 2000-03-12 Marius Vollmer <mvo@zagadka.ping.de>
3444
3445 * init.c (scm_standard_stream_to_port): Check whether the file
3446 descriptor is valid and substitute "/dev/null" when not.
3447
3448 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3449
3450 * coop-defs.h (struct timespec): Conditionally defined.
3451
3452 * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
3453 instead of ETIME.
3454
3455 * readline.c (match_paren): Bugfix: First arg to select is not
3456 number of descriptors but the number of the highest descriptor +
3457 1.
3458
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.
3463
3464 * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
3465
3466 * coop-defs.h (scm_mutex_trylock): New macro: alias for
3467 coop_mutex_trylock.
3468 (scm_cond_init): Changed definition to
3469 coop_new_condition_variable_init.
3470
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
3478 configure.in?
3479 (coop_condition_variable_timed_wait_mutex): New function.
3480 (coop_key_create, coop_setspecific, coop_getspecific,
3481 coop_key_delete): New functions.
3482
3483 * iselect.c (coop_timout_qinsert): Moved to coop.c
3484
3485 2000-03-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3486
3487 * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
3488 SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
3489
3490 * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
3491 Layout cleanups.
3492
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.
3496
3497 * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
3498 dealing with ilocs.
3499
3500 2000-03-11 Dale P. Smith <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
3501
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.
3505
3506 (logand, logior, logxor, logtest, logbit?): Extended scheme
3507 logical functions to use bignums from SCM.
3508
3509 (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
3510 lognot from using bignums.
3511
3512 Thu Mar 9 11:33:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3513
3514 * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
3515 eliminating some warnings.
3516
3517 * unif.c, strports.c, print.c, options.c: Fix some warnings on
3518 mis-use of SCM/long
3519
3520 * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
3521 what the scm_return_first* functions do.
3522
3523 2000-03-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
3524
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),
3530
3531 Wed Mar 8 10:15:59 2000 Greg J. Badros <gjb@cs.washington.edu>
3532
3533 * numbers.c: Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
3534 various logXXX primitives. Thanks Eric Moore!
3535
3536 Tue Mar 7 08:05:22 2000 Greg J. Badros <gjb@cs.washington.edu>
3537
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.
3542
3543 * hash.c: Docs, minor cleanup patch from Dirk Herrman.
3544
3545 Thu Mar 2 16:06:58 2000 Greg J. Badros <gjb@cs.washington.edu>
3546
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.
3550
3551 * __scm.h: Added SCM_ASSERT_TYPE macro.
3552
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)
3556
3557 * Makefile.am: Rename scm_validate.h to validate.h.
3558
3559 * *.c, *.h: Include validate.h, not scm_validate.h (old name's
3560 prefix was superfluous).
3561
3562 Thu Mar 2 15:33:12 2000 Greg J. Badros <gjb@cs.washington.edu>
3563
3564 * hashtab.c: Improved documentation for lots of functions. Added
3565 handwritten docs for `hash-fold'.
3566
3567 Thu Mar 2 15:13:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3568
3569 * list.c: Added hand-written docs for `del{q,v,ete}1!'.
3570
3571 Thu Mar 2 12:38:30 2000 Greg J. Badros <gjb@cs.washington.edu>
3572
3573 * list.c: Moved append docs to append! Thanks Dirk Hermann. Also,
3574 added append docs from R4RS.
3575
3576 * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
3577 Thanks Dirk Hermann!
3578
3579 * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
3580 deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
3581
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!
3585
3586 Sat Feb 19 12:20:12 2000 Greg J. Badros <gjb@cs.washington.edu>
3587
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!
3592
3593 Sun Feb 13 19:11:42 2000 Greg J. Badros <gjb@cs.washington.edu>
3594
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)
3602
3603 Sun Feb 13 18:12:19 2000 Greg J. Badros <gjb@cs.washington.edu>
3604
3605 * ports.c: Added docs for primitives missing them. Written by
3606 hand.
3607
3608 Sun Feb 13 09:40:36 2000 Greg J. Badros <gjb@cs.washington.edu>
3609
3610 * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
3611 just execing guile-func-name-check. Thanks Michael Livshin!
3612
3613 Thu Feb 10 11:43:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3614
3615 * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
3616 dead code. Patch from Michael Livshin.
3617
3618 * guile-doc-snarf.in: Tweak to work with Sun/HP sh. Patch from
3619 Michael Livshin.
3620
3621 2000-02-09 Gary Houston <ghouston@arglist.com>
3622
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
3627 OK now.
3628
3629 2000-02-08 Gary Houston <ghouston@arglist.com>
3630
3631 * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
3632 is not defined.
3633
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.
3637
3638 Tue Feb 8 13:57:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3639
3640 * ports.c: Doc patches from Richard Kim. Pasted from MIT Scheme.
3641 Thanks Richard!
3642
3643 Mon Feb 7 09:07:31 2000 Greg J. Badros <gjb@cs.washington.edu>
3644
3645 * macros.c: Doc patches from Richard Kim. Pasted from scm.texi.
3646
3647 Sun Feb 6 20:26:21 2000 Greg J. Badros <gjb@cs.washington.edu>
3648
3649 * pairs.c: Doc patches from Richard Kim. Pasted from MIT Scheme
3650 (which is GNU GPL'd).
3651
3652 2000-01-31 Gary Houston <ghouston@arglist.com>
3653
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>.
3656
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.
3661
3662 (scm_makfromstr): cosmetic changes.
3663
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.
3670
3671 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
3672
3673 2000-01-29 Gary Houston <ghouston@arglist.com>
3674
3675 * posix.c (scm_pipe): rewrote the docstring.
3676
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.
3682
3683 Thu Jan 27 10:14:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3684
3685 * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
3686 from Gregg Reynolds. Thanks Gregg!
3687
3688 Thu Jan 27 09:59:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3689
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.
3693
3694 Wed Jan 26 17:33:52 2000 Greg J. Badros <gjb@cs.washington.edu>
3695
3696 * throw.c: Factor out an #ifdef/#else/#endif choice more finely
3697 for maintainability.
3698
3699 * strop.c: Documentation added by Gregg A. Reynolds. Pasted in
3700 from qdocs, RnRs.
3701
3702 Wed Jan 26 10:02:11 2000 Greg J. Badros <gjb@cs.washington.edu>
3703
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'
3706 instead).
3707
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
3711 (rnrs) note.
3712
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.
3718
3719 Tue Jan 25 17:15:47 2000 Greg J. Badros <gjb@cs.washington.edu>
3720
3721 * sort.c: typo in comment fixed.
3722
3723 * keywords.c: Added documentation.
3724
3725 * guardians.c: Added documentation (could be better).
3726
3727 * gc.c: Added docs for gc-set-debug-check-freelist.
3728
3729 * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
3730
3731 * boolean.c: Added docs for `not', `boolean?' (by hand).
3732
3733 Tue Jan 25 13:28:56 2000 Greg J. Badros <gjb@cs.washington.edu>
3734
3735 * random.c: Added documentation, from SLIB page:
3736 http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
3737
3738 Mon Jan 24 17:50:20 2000 Greg J. Badros <gjb@cs.washington.edu>
3739
3740 * variable.c, version.c: Added documentation, written by hand
3741 since I could not find anything already written that was
3742 relevant.
3743
3744 2000-01-23 Gary Houston <ghouston@arglist.com>
3745
3746 * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
3747 not defined (thanks to Richard Y. Kim).
3748
3749 Thu Jan 20 13:00:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3750
3751 * Makefile.in: Removed, this is auto-generated.
3752
3753 Thu Jan 20 11:33:47 2000 Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
3754
3755 * list.c: Put some variable initialization code at the point of
3756 declaration; Added a comment for list*; Formatting changes.
3757
3758 * load.c: use SCM_NNULLP to make sure the end of a list is not
3759 reached yet.
3760
3761 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3762
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.)
3767
3768 * net_db.c (scm_resolv_error): Cast result from hstrerror.
3769
3770 * strports.c (st_end_input): Inserted parenthesis to get operator
3771 grouping correct.
3772
3773 * list.h (scm_init_list): Removed SCM_P around prototypes.
3774
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.
3778
3779 Tue Jan 18 13:21:08 2000 Mikael Djurfeldt <mdj@r11n07-s.pdc.kth.se>
3780
3781 * posix.c (scm_mknod): Escape " occuring inside docstring.
3782
3783 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3784
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.
3793
3794 * filesys.c (scm_chmod), simpos.c (scm_system), version
3795 (scm_version), vports (scm_make_soft_port): Escape " occuring
3796 inside docstring.
3797
3798 Mon Jan 17 11:41:22 2000 Greg J. Badros <gjb@cs.washington.edu>
3799
3800 * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
3801 SCM_VALIDATE_LONG_COPY
3802
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.
3807
3808 2000-01-14 <mstachow@alum.mit.edu>
3809
3810 * Makefile.am: Augment path when running guile-doc-snarf so
3811 guile-func-name-check is found.
3812
3813 Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
3814
3815 * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
3816 def, not SCM_MAKINUM(def); thanks Janis Bzerins!
3817
3818 Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3819
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.
3823
3824 Tue Jan 11 18:24:18 2000 Greg J. Badros <gjb@cs.washington.edu>
3825
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.
3832
3833 Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
3834
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
3839 variants.
3840
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).
3845
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!
3851
3852 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
3853 SCM_VALIDATE_INUM_COPY once where it should've been used.
3854
3855 * fluids.c (scm_internal_with_fluids): Use
3856 SCM_VALIDATE_LIST_COPYLEN.
3857
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.
3862
3863 * evalext.c: line-break change on 1 line.
3864
3865 * eval.c (nconc2last): Takes a non-empty list as its first
3866 argument, not just a list.
3867
3868 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
3869
3870 Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3871
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
3874 where possible.
3875
3876 * symbols.c (scm_sysintern0): Fixed the function name in a
3877 scm_misc_error invocation.
3878
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.
3881
3882 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
3883 used before but should've been.
3884
3885 2000-01-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3886
3887 * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
3888 SCM_FUNC_CAST_ARBITRARY_ARGS.
3889
3890 Tue Jan 11 13:44:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3891
3892 * guile-func-name-check.in: Added this script to statically check
3893 #define FUNC_NAME, #undef FUNC_NAME in the source.
3894
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
3897 script.
3898
3899 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
3900 Caught by new guile-func-name-check-script.
3901
3902 * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
3903
3904 * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
3905 guile-func-name-check.
3906
3907 * guile-doc-snarf.in: Run guile-func-name-check on the file before
3908 doing the snarf.
3909
3910 Tue Jan 11 11:31:10 2000 Greg J. Badros <gjb@cs.washington.edu>
3911
3912 * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
3913 port function take const void*, not void*.
3914
3915 Tue Jan 11 11:18:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3916
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).
3922
3923 Tue Jan 11 10:41:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3924
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.
3929
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
3935 string.
3936
3937 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
3938
3939 * backtrace.c (scm_display_error_message): Rewrote to use
3940 scm_simple_format() procedure.
3941
3942 * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
3943
3944 2000-01-09 Marius Vollmer <mvo@zagadka.ping.de>
3945
3946 Finally applied the libltdl patch from Thomas Tanner, with slight
3947 modifications.
3948
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.
3953
3954 1999-07-25 Thomas Tanner <tanner@ffii.org>
3955
3956 * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
3957 (obsolete)
3958 * Makefile.am: likewise, add INCLTDL (libltdl headers) to
3959 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
3960 against libltdl
3961 * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
3962 * guile.c: register preloaded modules
3963 * scmconfig.h.in: remove obsolete symbols
3964
3965 2000-01-09 Gary Houston <ghouston@arglist.com>
3966
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
3976 anything useful.
3977 (scm_localtime, scm_strftime, scm_mktime): call tzset if
3978 LOCALTIME_CACHE is defined.
3979
3980 2000-01-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3981
3982 * posix.c (scm_sync): Return SCM_UNSPECIFIED.
3983
3984 2000-01-09 Gary Houston <ghouston@arglist.com>
3985
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.
3989
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,
3994 scm_sync),
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.
4002
4003 Sat Jan 8 19:52:04 2000 Greg J. Badros <gjb@cs.washington.edu>
4004
4005 * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
4006
4007 Sat Jan 8 17:06:46 2000 Greg J. Badros <gjb@cs.washington.edu>
4008
4009 * backtrace.c: Fix spelling typo in a comment.
4010
4011 * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
4012 text. Reformatted some of the expansions.
4013
4014 Fri Jan 7 15:50:46 2000 Greg J. Badros <gjb@cs.washington.edu>
4015
4016 * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
4017 report the position of the argument.
4018
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
4021 argument.
4022
4023 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
4024
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.
4028
4029 Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
4030
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).
4037
4038 2000-01-07 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
4039
4040 * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
4041 snarf macro definitions.
4042
4043 2000-01-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4044
4045 * chars.c (scm_integer_to_char): Use Greg's nice
4046 SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
4047 adherence to R5RS.
4048
4049 Thu Jan 6 11:48:49 2000 Greg J. Badros <gjb@cs.washington.edu>
4050
4051 * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
4052
4053 Thu Jan 6 11:22:53 2000 Greg J. Badros <gjb@cs.washington.edu>
4054
4055 * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
4056 instead of GUILE_PROC.
4057
4058 Thu Jan 6 11:21:49 2000 Greg J. Badros <gjb@cs.washington.edu>
4059
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
4062 macro call.
4063
4064 Thu Jan 6 09:54:33 2000 Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
4065
4066 * scm_validate.h: Remove some redundant NIMP tests.
4067
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.
4082
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.
4087
4088 Wed Jan 5 11:24:53 2000 Greg J. Badros <gjb@cs.washington.edu>
4089
4090 * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
4091 macros and SCM_DEFINE macros to match GNU coding standards.
4092
4093 Wed Jan 5 11:04:24 2000 Greg J. Badros <gjb@cs.washington.edu>
4094
4095 * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
4096
4097 Wed Jan 5 10:59:06 2000 Greg J. Badros <gjb@cs.washington.edu>
4098
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.
4102
4103 Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
4104
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).
4108
4109 * guile-snarf.awk.in: Do argument/number mismatch checking and
4110 print warnings in an Emacs compile-mode parseable format.
4111
4112 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
4113 SCM_OUTOFRANGE as 3rd argument.
4114
4115 * random.c: Fix argument/number mismatch (that I introduced :-( ).
4116
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.
4121
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.
4125
4126 * ramap.c: Remove extraneous #undef FUNC_NAME.
4127
4128 Wed Jan 5 08:36:38 2000 Greg J. Badros <gjb@cs.washington.edu>
4129
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.
4133
4134 Wed Jan 5 08:15:04 2000 Greg J. Badros <gjb@cs.washington.edu>
4135
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!
4140
4141 * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
4142 uses in random.c.
4143
4144 * ramap.c: whitespace change.
4145
4146 Tue Jan 4 14:21:35 2000 Greg J. Badros <gjb@cs.washington.edu>
4147
4148 * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
4149 removals from Dirk Hermann.
4150
4151 * alist.c: Rename formals to match the parameter names in the
4152 documentation, updates to documentation. Thanks Dirk Hermann!
4153
4154 2000-01-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4155
4156 * eval.c (SCM_CEVAL): Reverse order of
4157 scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
4158 (Thanks to Brad Knotwell.)
4159
4160 Mon Jan 3 08:30:02 2000 Greg Harvey <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
4161
4162 * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
4163 allocated cell.
4164
4165 * pairs.h: Added a comment about the need for the SCM_SETCAR in
4166 SCM_NEWCELL macro.
4167
4168 Mon Jan 3 08:25:19 2000 Greg J. Badros <gjb@cs.washington.edu>
4169
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.
4173
