3 * numbers.c (scm_adjbig): Use SCM_BDIGITS instead of SCM_CHARS.
5 (big2str, scm_bigprint): Use SCM_STRING_CHARS instead of
8 * vectors.c (scm_vector_set_length_x): Distinguish between
9 strings, scheme vectors and uniform vectors, thus getting rid of
10 references to SCM_CHARS. (The code still needs improvement.)
12 2000-09-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
14 * eval.c (scm_m_letrec1, SCM_CEVAL, SCM_APPLY): Use
15 SCM_STRING_U?CHARS or SCM_SYMBOL_U?CHARS instead of SCM_U?CHARS.

83 SCM_SYMBOL_CHARS instead of SCM_CHARS.
85 2000-09-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
87 * strings.h (SCM_STRING_CHARS): Added, should be used instead of
88 SCM_CHARS whenever the argument is known to be a string.
90 (SCM_SLOPPY_STRINGP): Deprecated.
92 * symbols.h (SCM_SYMBOL_CHARS): Added, should be used instead of
93 SCM_CHARS whenever the argument is known to be a symbol.
95 2000-09-22 Neil Jerram <neil@ossau.uklinux.net>
97 * struct.c (scm_make_struct): Fix texinfo warning in docstring by
98 using @pxref rather than @xref.
100 * root.c (scm_call_with_dynamic_root): Fix texinfo warning in
101 docstring by using @code for (thunk) rather than @var.
103 2000-09-20 Marius Vollmer <mvo@zagadka.ping.de>
105 * numbers.c (scm_istr2flo): Throw an `out of range' error when
106 exponent is too large instead of returning `#f'. The rationale is
107 that in this case the string represents a valid number but we

112 * symbols.c (scm_intern_obarray_soft,
113 scm_sysintern0_no_module_lookup): Make sure that symbol

119 * throw.c (scm_handle_by_message): Added a FIXME comment.
121 (scm_ithrow): Removed some redundant tests. When compiling on

141 This patch unifies the formerly distinct ssymbol and msymbol types
142 to a common symbol type scm_tc7_symbol. The representation of the
143 new symbol type uses a double cell with the following layout:
144 <type/length, chars, raw_hash, prop-pair>, where the car of
145 prop-pair holds the symbol's function property and the cdr of
146 prop-pair holds the symbol's other properties. In the long run,
147 these properties will be removed. Then, the generic property
148 functions will be uses.
150 * eval.c (SCM_CEVAL), objects.c (scm_class_of), print.c
151 (scm_iprin1), tag.c (scm_tag): Use scm_tc7_symbol instead of
152 scm_tc7_ssymbol, scm_tc7_msymbol or scm_tcs_symbols.
154 * gc.c (scm_gc_mark): Mark the symbols property pair.
156 (scm_gc_sweep): There are no symbol slots any more.
158 * hash.c (scm_hasher): Instead of re-calculating the hash value
159 of a symbol, use the raw_hash value stored in the symbol itself.
161 * properties.h: Fix typo.
163 * strings.[ch] (scm_makstr, scm_makfromstr): The slot parameter
164 is not used any more.
166 * symbols.[ch] (scm_strhash): Deprecated, replaced by a macro.
168 (scm_intern_obarray_soft): Made softness parameter unsigned.
170 (scm_string_hash): New function with the same functionality as
171 scm_strhash had before, except that the hash value is not adjusted
172 to a hash table size. Instead, the 'raw' hash value is returned.
174 * symbols.c (duplicate_string): New static convenience function.
176 (scm_sym2vcell, scm_sym2ovcell_soft, scm_intern_obarray_soft):
177 Renamed local variable from scm_hash to hash.
179 (scm_intern_obarray_soft): Don't check for a negative softness
180 any more. When generating symbol cells, use the new layout and
181 store the raw hash value in the symbol's cell.
183 (scm_symbol_to_string): Removed unnecessary cast.
185 (scm_intern_symbol, scm_unintern_symbol): Use scm_string_hash to
186 determine the hash values.
188 (msymbolize): Removed.
190 (scm_symbol_fref, scm_symbol_pref, scm_symbol_fset_x,
191 scm_symbol_pset_x, scm_symbol_hash): No need to distinguish
192 between different symbol types any more.
194 (scm_symbol_hash): Comment fixed.
196 * symbols.h: Comment about the distinction between ssymbols and
199 (SCM_SYMBOLP, SCM_ROSTRINGP): No need to distinguish between
200 different symbol types any more.
202 (SCM_PROP_SLOTS, SCM_SET_PROP_SLOTS): Added.
204 (SCM_SYMBOL_FUNC, SCM_SET_SYMBOL_FUNC, SCM_SYMBOL_PROPS,
205 SCM_SET_SYMBOL_PROPS, SCM_SYMBOL_HASH, SCM_SET_SYMBOL_HASH): Use
206 the new symbol cell layout.
208 * tags.h (scm_tc7_ssymbol, scm_tc7_msymbol, scm_tcs_symbols):
211 2000-09-12 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
213 * symbols.h (scm_gentemp): Declared.
215 * symbols.c (scm_gensym): Reimplemented. Now only takes one
216 optional argument which should be a *string*.
217 (scm_gentemp): Reimplemented and moved from boot-9.scm.
219 2000-09-10 Keisuke Nishida <kxn30@po.cwru.edu>
221 * modules.c: Use applicable smobs for eval closures instead of

232 * symbols.c: Include "libguile/smob.h".
233 (scm_sym2vcell): Call scm_eval_closure_lookup directly if THUNK
236 2000-09-10 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
238 * Makefile.am (.x.doc): Bugfix: Added $(srcdir) to path in order
239 to allow for builds in separate tree.
241 * symbols.c (scm_gensym): Bugfixed my previous bugfix. (Thanks to
244 2000-09-10 Keisuke Nishida <kxn30@po.cwru.edu>

251 obarray_remove): Make sure the hash value is a valid obarray
254 (obarray_enter, obarray_remove): Documentation improved.
256 (obarray_replace): Added.

261 2000-09-05 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
263 * symbols.c (scm_gensym): Check that argument is a symbol, not a
264 string. (Thanks to Ralf Mattes.)
266 2000-09-05 Marius Vollmer <mvo@zagadka.ping.de>
268 * init.c: Include "libguile/properties.h".
270 * gh_data.c (gh_scm2char): Validate that argument is a character.
272 2000-08-25 Dirk Herrmann <D.Herrmann@tu-bs.de>

276 functions, make sure that we really got an environment.
278 2000-09-03 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
280 * validate.h (SCM_VALIDATE_NUMBER_DEF_COPY): New macro.
282 2000-09-03 Marius Vollmer <mvo@zagadka.ping.de>
284 * Makefile.am (.x.doc): Pretend to create .doc files from .x files
285 and give explicit dependencies for .x files that depend on
286 generated files. This allows parallel builds. Thanks to Matthias
289 2000-08-27 Marius Vollmer <mvo@zagadka.ping.de>
291 * Makefile.am: Added gc_os_dep.c, properties.c, properties.x,
292 properties.h and properties.doc in the suitable places.
294 * init.h (scm_init_guile): New prototype.
296 * init.c (scm_init_guile, scm_init_guile_1): New interface for
297 initializing Guile that does return to the caller.
298 (scm_boot_guile_1): Use scm_init_guile_1 to initialize Guile.
299 Do not establish a catch-all, this is no longer needed.
301 * root.h (scm_properties_whash): New `sys_protect', used in
304 * throw.c (scm_ithrow): Perform catch-all handling here when no
305 suitable handler has been found. That way, we don't have to rely
306 on the user establishing a catch-all, which might be difficult for
307 him if he is using scm_init_guile instead of scm_boot_guile.
309 2000-09-03 Neil Jerram <neil@ossau.uklinux.net>
311 * vectors.c (scm_vector): Docstring: add @deffnx line for

316 (scm_array_set_x): Docstring: add @deffnx line for
319 * symbols.c (scm_symbol_to_string): Docstring: complete an
320 incomplete Texinfo reference to a node in r4rs.texi.
321 (scm_symbol_to_string): Escape double quotes correctly within
324 * struct.c (scm_make_struct, scm_make_vtable_vtable): Docstring
325 fixes: `@dots' changed to `@dots{}'.
327 * strop.c (scm_substring_move_x): Docstring: add @deffnx lines for

352 2000-09-03 Michael Livshin <mlivshin@bigfoot.com>
354 the following changes let Guile get rid of the `allocated' cell
357 * smob.c (scm_smob_prehistory): don't init the "allocated" smob
360 * tags.h (scm_tc16_allocated): removed.
362 * gc.h: removed now-obsolete comments about the `allocated' cell
364 (SCM_NEWCELL): don't change cell type to `allocated'.
365 (SCM_NEWCELL2): ditto.
367 * gc.c (scm_mark_locations): mark freecells too, and don't worry
368 about any possible false positives.
369 (scm_debug_newcell): don't change cell type to `allocated'.
370 (scm_debug_newcell2): ditto.
371 (scm_gc_for_newcell): ditto.
372 (scm_gc_mark): remove the tc16_allocated case.
374 2000-08-26 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
376 * gdbint.c (gdb_print): Removed superfluous macro definition.
378 * objects.c (scm_init_objects), print.c (scm_init_print), struct.c
379 (scm_init_struct): First arg to scm_make_vtable_vtable should be a
380 string, not a symbol. (`make-vtable-vtable' needs to append this
381 string to another string and then pass it through
382 `make-struct-layout'.)
384 * stacks.c (scm_init_stacks): Pass a string, not a layout object,
385 to scm_make_vtable_vtable. (Thanks to Dale P. Smith.)
387 * struct.c (scm_make_struct_layout): Removed reference to
388 "read-only string" in comment; Check that argument is a string.
389 (scm_make_vtable_vtable): Check that argument is a string.
391 * environments.c (scm_init_environments): All internal includes in
392 libguile must use the prefix "libguile/" in path names since inly
393 the top-level source directory is on the include list. (That, in
394 turn, is because we want to distinguish between system header
395 files and hedares files internal to libguile.)
397 * strings.c (scm_make_shared_substring, scm_read_only_string_p):
399 (scm_string_length, scm_string_ref, scm_substring,
400 scm_string_append): Don't accept symbols as arguments (R5RS).
402 2000-08-25 Neil Jerram <neil@ossau.uklinux.net>
404 * ports.c (scm_set_port_column_x): Fix docstring so that it
405 mentions set-port-line! rather than set-port-column! twice.
407 * guardians.c (scm_make_guardian): Remove spurious . from doc string.
409 2000-08-25 Dirk Herrmann <D.Herrmann@tu-bs.de>

428 (scm_set_smob_apply): New function.
429 (scm_smob_apply_0, scm_smob_apply_1, scm_smob_apply_2,
430 scm_smob_apply_3): New functions.
431 * eval.c (SCM_CEVAL, SCM_APPLY): Added dispatch for applicable smobs.
432 * procs.c (scm_procedure_p): Check applicable smobs.
434 2000-08-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
436 * Makefile.am (BUILT_SOURCES): Experimentally added scmconfig.h
437 also here. (This is supposed to make sure that scmconfig.h is
438 built before all sources in order to prevent that everything has
439 to be rebuilt again. Hope it works---I'm just guessing. :)
441 * fluids.c (scm_fluid_set_x): Return SCM_UNSPECIFIED.
443 2000-08-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
445 * gc.c (scm_gc_mark): Don't use GUILE_DEBUG flag to compile in
446 extra tests. (GUILE_DEBUG is only supposed to make extra
447 debugging functions available.)
449 2000-08-21 Michael Livshin <mlivshin@bigfoot.com>
451 * gc.h (SCM_GC_CARD_N_CELLS): change to be a nice non-confusing
454 2000-08-19 Michael Livshin <mlivshin@bigfoot.com>
456 * gc.c (scm_gc_sweep): added a `continue' statement that have
457 fallen through the cracks in the merge. thanks to Shuji Narazaki!
459 * gc.h: removed some stuff that broke compilation for people and
460 wasn't actually needed anyway.
462 2000-08-18 Neil Jerram <neil@ossau.uklinux.net>
464 * filesys.c (scm_fcntl): Docstring fix - missing newlines inserted.
466 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_sethost,
467 scm_setnet, setproto, setserv): Argument names changed to match
470 * feature.c (scm_program_arguments): New docstring.
472 * simpos.c (scm_getenv): Reflow docstring.
474 * eq.c (scm_eq_p, scm_eqv_p, scm_equal_p): Add texinfo markup to
477 * chars.c (scm_char*): Docstring fixes - texinfo markup.
479 2000-08-18 Neil Jerram <neil@ossau.uklinux.net>
481 * boolean.c (scm_not, scm_boolean_p): Docstring fixes - add
482 texinfo markup and remove trailing newlines.
484 2000-08-17 Michael Livshin <mlivshin@bigfoot.com>
486 this changes the Guile GC to use cards (aka "chunklets").
487 (most of the ideas and some of the code are by Greg Harvey, though
488 the code is probably unrecognizable now. the original chunklet
489 proposal, way back, is by Dale Jordan).
491 * tags.h: (SCM_GCTYPE16, SCM_GCCDR, SCM_GC[8]MARKP,
492 SCM_SETGC[8]MARK, SCM_CLRGC[8]MARK): moved from here into gc.h.
493 some (most) of these are probably going to be deprecated.
495 * gc.h (SCM_MARKEDP): simplified, there are no different mark bit
497 (SCM_GC_CARD_*, SCM_C_BVEC_*): lots of new macros to deal with
498 cards and bvecs (bit-vectors).
500 * gc.c: (scm_default_init_heap_size_*): defined to take cards into
501 account, but keeping more or less the same values as previously.
502 added some simple helper macros.
503 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK): defined to take cards
505 (BVEC_*, scm_mark_space_t, current_mark_space, mark_space_ptr,
506 current_mark_space_offset, mark_space_head, get_bvec,
507 clear_mark_space): new functions and supporting variables, types
508 and macros that implement mark space management.
509 (scm_igc): clear the mark space (all of it) before beginning the
511 (scm_gc_mark): changed the tests for rogue cells, much simplified
512 throughout (no different mark bit locations to worry about now).
513 (scm_mark_locations): don't consider card header cells.
515 (scm_gc_sweep): simplified.
516 (init_heap_seg): changed to take cards into account.
518 2000-08-16 Michael Livshin <mlivshin@bigfoot.com>
520 * stime.c (scm_c_get_internal_run_time): new function, same as
521 scm_get_internal_run_time but returns a long. it's used by the GC
522 for timekeeping, since with scm_get_internal_run_time there is a
523 (extremely theoretical) possibility of consing.
524 (scm_get_internal_run_time): redefined in terms of
525 scm_c_get_internal_run_time.
527 * stime.h: added prototype for scm_c_get_internal_run_time.
529 * gc.c (scm_gc_stats): add more obscure stats, such as: mark time,
530 sweep time, total marked cells, total swept cells, and number of
531 times GC was invoked.
532 (gc_start_stats): renamed from scm_gc_start, made static, taught
533 to init the new stats.
534 (gc_end_stats): renamed from scm_gc_end, made static, taught to
535 calculate the new stats.
536 (scm_igc): don't call gc_start_stats unless we are sure that we
537 are indeed going to collect. also, added some timekeeping between
538 the mark and sweep phases.
539 (scm_gc_sweep): count number of cells we sweep as we go.
541 * gc.h: removed prototypes for scm_gc_{start,end}.
543 2000-08-13 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
545 * alist.c (scm_assq, scm_assv, scm_assoc): Report argument type
546 error for the alist rather than the sublist where the type
547 mismatch is discovered.
549 2000-08-13 Neil Jerram <neil@ossau.uklinux.net>
551 * root.c (s_scm_call_with_dynamic_root): Docstring fix - rogue
554 2000-08-12 Neil Jerram <neil@ossau.uklinux.net>
556 * numbers.c (scm_ash): Docstring fix - missing newlines.
558 * ports.c (scm_port_filename): Docstring fix - missing newline.
560 * strports.c (scm_eval_string): Docstring fix - missing newline.
562 * vports.c (s_scm_make_soft_port): Docstring updated so that

583 * dynl.c: Remove surplus newlines from end of docstrings.
585 2000-08-11 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
587 * eval.c (scm_eval): Backward incompatible change: Now takes an
588 environment specifier as second arg. `eval' hereby becomes R5RS

616 scm_interaction_environment ().
618 * script.c (scm_shell): Pass scm_the_root_module () as second arg
621 * load.c (load): Use `scm_selected_module' to compute second arg
622 to new scm_i_eval_x; Don't call it if module system hasn't booted.
623 (scm_read_and_eval_x): Deprecated.
624 #include "modules.h".
626 * debug.c (scm_local_eval): Use scm_i_eval and scm_i_eval_x.

634 2000-08-09 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
636 The following changes are intended to ensure that struct instances
637 are freed before their vtables. It's optimized for the most
638 common case, which is freeing of struct instances.
640 * gc.c (scm_gc_mark, scm_gc_sweep): Remove vcell = 1 magic.
641 (scm_structs_to_free): New variable.
642 (scm_gc_sweep): Hook up structs to free on the scm_structs_to_free
645 * struct.h (SCM_STRUCT_GC_CHAIN, SCM_SET_STRUCT_GC_CHAIN): New
647 (scm_structs_to_free, scm_struct_prehistory): Declare.
649 * struct.c (scm_make_struct, scm_make_vtable_vtable): Structs
650 handles are now double cells; Initialize SCM_STRUCT_GC_CHAIN to
652 (scm_struct_gc_init, scm_free_structs): New GC C hooks.
653 (scm_struct_prehistory): Install them.
655 * init.c (scm_boot_guile_1): Call scm_struct_prehistory.
657 2000-08-06 Marius Vollmer <mvo@zagadka.ping.de>
659 * read.c (scm_flush_ws): Include filename in error message when it
662 2000-08-05 Marius Vollmer <mvo@zagadka.ping.de>
664 * iselect.c: Include <unistd.h>. Thanks to Bertrand Petit!
666 2000-08-02 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
668 * struct.c (scm_make_struct_layout, scm_make_struct,
669 scm_make_vtable_vtable): Updated documentation.
671 * print.c (scm_simple_format): Bugfix: Coerce port before using
674 2000-07-31 Gary Houston <ghouston@arglist.com>
676 * net_db.c: declare h_errno only if HAVE_H_ERRNO is not defined
677 (thanks to Richard Kim for the bug report).
679 2000-07-30 Marius Vollmer <mvo@zagadka.ping.de>
681 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
682 scm_assoc_remove_x): Use scm_delq1_x instead of scm_delq_x, since
683 using the latter is pointless.
685 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
687 * gc.c (scm_gc_sweep): Renamed local variable from 'free' to
688 'free_struct_data' to avoid confusion with stdlib's 'free'.
690 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
692 * vectors.c (scm_make_vector): Fix the initialization order of
693 the vector such that the type cell is initialized last.
695 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
697 * struct.[ch] (scm_struct_init): Made static. Fixed not to rely
698 on the struct cell to be fully initialized.
700 * struct.c (scm_make_struct, scm_make_vtable_vtable): Fix the
701 initialization order of the struct such that the type cell is
704 2000-07-25 Marius Vollmer <mvo@zagadka.ping.de>
706 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
707 scm_assoc_remove_x): Remove only the first cell with a matching
710 2000-07-24 Marius Vollmer <mvo@zagadka.ping.de>
712 * stime.c (scm_strftime): Recognize a return value of zero from
713 strftime as buffer overflow and take care to detect a valid zero
714 length result regardless. Thanks to David Barts!
716 2000-07-23 Marius Vollmer <mvo@zagadka.ping.de>
718 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
719 scm_assoc_remove_x): Remove all cells whose key is eq, eqv, or
720 equal (respectively) to the argument key, not all cells that are
721 eq, eqv, or equal to the first cell with the argument key. Thanks
724 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
726 * gc.h (SCM_FREE_CELL_CDR, SCM_SET_FREE_CELL_CDR), hooks.c
727 (make_hook), modules.c (OBARRAY, USES, BINDER): Pack and unpack
728 SCM values appropriately.
730 * modules.c (scm_standard_eval_closure): Don't pass an inum to
731 scm_makcclo, but rather a long value.
733 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
735 read.c (scm_lreadrecparen), srcprop.c (scm_set_source_property_x):
736 SCM_SETCDR and SCM_WHASHSET macros don't deliver a return value.
737 Thanks to Han-Wen Nienhuys for the bug report.
739 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
741 * root.[ch] (scm_call_catching_errors): Deprecated.
743 * root.c (scm_init_root): Initialize the root smob type using the
744 standard initialization functions.
746 2000-07-17 Marius Vollmer <mvo@zagadka.ping.de>
748 * eval.c (unmemocopy): Don't rely on V being a list of at least
749 one element. Thanks to Bill Schottstaedt!
751 2000-07-15 Michael Livshin <mlivshin@bigfoot.com>
753 * gc.c (scm_done_free): new.
754 expanded comments about scm_done_malloc.
756 * gc.h: added prototype for scm_done_free
758 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
760 * gc.h (scm_take_stdin): Removed.
762 * gc.h (SCM_VALIDATE_CELL): Delegate cell checks to function
763 scm_assert_cell_valid to allow extensions to the checking
764 functionality without need to recompile everything.
766 * gc.[ch] (scm_assert_cell_valid, scm_set_debug_cell_accesses_x):
767 Added as conditionally compiled functions for the case that
768 SCM_DEBUG_CELL_ACCESSES is enabled.
770 * gc.c (debug_cells_p): Added to indicate whether compile-time
771 included cell access debugging is run-time enabled.
773 * gc.[ch] (scm_gc_running_p): Added to indicate that scm_igc is
774 being executed. Intended to be used instead of scm_gc_heap_lock
777 * error.c (scm_error), gdbint.c (SCM_GC_P): Use scm_gc_running_p
778 instead of scm_gc_heap_lock.
780 * gc.c (scm_igc): Set scm_gc_running_p to true while running.
782 * gc.c (scm_mark_locations): Don't mark free cells.
784 * weaks.c (scm_scan_weak_vectors): Use SCM_FREE_CELL_P instead of
787 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
789 * gc.c (scm_mark_locations): Minimized some variable scopes and
790 simplified the code a bit.
792 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
794 * gc.h (SCM_SET_FREE_CELL_TYPE, SCM_SET_FREE_CELL_CDR,
795 SCM_FREE_CELL_P, SCM_FREE_CELL_CDR): Added since free cells
796 should not be accessed via SCM_C[AD]R. Further, using dedicated
797 macros to access free cells allows all other cell accessing macros
798 to treat acesses to free cells as errors, thus enabling better
799 error checks for cell accesses. SCM_FREE_CELL_P is supposed to
800 replace SCM_FREEP some time.
802 * gc.h (SCM_NEWCELL, SCM_NEWCELL2), gc.c (map_free_list,
803 free_list_length, scm_check_freelist, scm_debug_newcell,
804 scm_debug_newcell2, freelist_length, scm_gc_for_newcell,
805 scm_gc_mark, scm_gc_sweep, init_heap_seg): Only use the dedicated
806 cell accessors when accessing free cells.
808 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
810 * gc.h (SCM_CELL_WORD, SCM_CELL_OBJECT): Treat the referenced
811 object as const in order to make the compiler warn about code like
812 SCM_CELL_WORD (x, n) = y. Instead, SCM_SET_CELL_WORD (x, n, y)
815 (SCM_CELL_WORD_LOC, SCM_CARLOC, SCM_CDRLOC): Return the address
816 as an address to a non-const object, since these macros are used
817 to allow direct write access to objects.
819 2000-07-07 Dirk Herrmann <D.Herrmann@tu-bs.de>
821 * hashtab.c (scm_hash_fn_create_handle_x): Signal an error if the
822 given hash table has no slots.
824 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
826 * gc.c (policy_on_error): Added in order to allow alloc_some_heap
827 to react to malloc failures in a context dependent way.
829 (scm_check_freelist): No need to flush streams before abort().
831 (scm_gc_for_newcell): Try to allocate new memory in three phases:
832 grow heap if preferred, if still no memory available collect
833 garbage, if still no memory available grow heap.
835 (heap_segment_table_size): Added to always reflect the actual
836 size of the heap segment table, because scm_n_heap_segs may differ
837 from the heap segment table size.
839 (alloc_some_heap): In case of malloc failure, react according to
840 the new policy_on_error parameter (either return to caller or
841 abort immediately). Further, keep heap_segment_table_size up to
844 (scm_init_storage): Initialize heap_segment_table_size.
846 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
848 * gh.h: Don't include <stdio.h>. Thanks to Han-Wen Nienhuys for
851 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
853 * __scm.h (SCM_OUTOFRANGE, SCM_NALLOC, SCM_HUP_SIGNAL,
854 SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL,
855 SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL, SCM_SIG_ORD,
856 SCM_ORD_SIG, SCM_NUM_SIGS): Re-introduce these as deprecated
859 * error.c (scm_wta): Re-introduce dispatching for SCM_OUTOFRANGE
860 and SCM_NALLOC, but as a deprecated feature.
862 2000-06-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
864 * debug.c: Added #include fluids.h.
866 * numbers.c (scm_gr_p, scm_leq_p, scm_geq_p): Turned into
867 primitive generics. (Thanks to Nicolas Neuss.)
869 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
871 * gc.c (alloc_some_heap): Use scm_memory_error to indicate a
872 failed attempt to get additional memory from the system.
874 (scm_gc_for_newcell): Changed the control structure to make the
875 behaviour explicit for the case that gc is not able to free any
878 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
880 * __scm.h (SCM_OUTOFRANGE): Removed.
882 * error.c (scm_wta): Removed sick dispatch code for range
883 errors. (More sick dispatches still to be removed.)
885 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
886 scm_hash_fn_remove_x): Eliminate redundant test for if unsigned
887 value is non-negative. Use scm_out_of_range to signal range
890 * hooks.c (make_hook), unif.c (scm_aind): Use scm_out_of_range to
893 * list.c (scm_list_ref, scm_list_set_x, scm_list_cdr_set_x): Fix
894 error reporting (now uses original input parameter to report wrong
895 type argument errors). Use SCM_OUT_OF_RANGE to report range
896 errors and SCM_WRONG_TYPE_ARG to report type errors.
898 * strings.c (scm_substring): Make range checks for negative
899 values explicit (former behaviour relied on an implicit
900 conversion from signed to unsigned). Don't use SCM_ASSERT for
903 * unif.c (scm_aind, scm_transpose_array, scm_bit_set_star_x,
904 scm_bit_count_star): Use scm_out_of_range to signal range
907 * unif.c (scm_transpose_array, scm_bit_position), vectors.c
908 (scm_vector_ref, scm_vector_set_x, scm_vector_move_left_x,
909 scm_vector_move_right_x): Use SCM_ASSERT_RANGE to check ranges.
911 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
913 * validate.h (SCM_VALIDATE_INUM_MIN_COPY,
914 SCM_VALIDATE_INUM_MIN_DEF_COPY, SCM_VALIDATE_INUM_RANGE_COPY):
915 Perform all range checks based on the input value. The former way
916 of using the value that is assigned to the target variable fails
917 if the assignment to the target variable itself can change the
918 value because of type conversion.
920 (SCM_ASSERT_RANGE): Use scm_out_of_range to signal range errors.
922 2000-06-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
924 * gc.c (scm_gc_for_newcell): Behave gracefully also if scm_igc
925 doesn't yield any new cells. In theory this could happen if all
926 cells allocated with NEWCELL are either in use or conservatively
927 marked and all cluster spine cells are conservatively marked.
930 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
932 * __scm.h (SCM_NALLOC): Removed.
934 * error.c (scm_wta): Removed sick dispatch code for memory
935 errors. (More sick dispatches still to be removed.)
937 * numbers.c (scm_mkbig, scm_adjbig), ports.c (scm_make_port_type),
938 random.c (scm_i_copy_rstate, scm_c_make_rstate), smob.c
939 (scm_make_smob_type), srcprop.c (scm_make_srcprops), vectors.c
940 (scm_vector_set_length_x): Now using scm_memory_error to signal
943 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
945 * __scm.h: Removed some commented code and fixed some comments.
947 (SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL,
948 SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL,
949 SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS): Removed.
951 * async.c: Removed some commented code.
953 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
955 * gc.c (scm_gc_mark, scm_gc_sweep, scm_must_malloc,
956 scm_must_realloc, scm_must_free, alloc_some_heap): Use the
957 appropriate error signalling function.
959 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
961 * root.h (scm_first_type): Removed.
963 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
965 * gc.c (MIN_GC_YIELD): Removed.
967 2000-06-28 Michael Livshin <mlivshin@bigfoot.com>
969 * gc.c (scm_gc_for_newcell): don't try to do GC if it's blocked,
972 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
974 * async.c (scm_gc_async, scm_gc_vcell, scm_sys_gc_async_thunk):
977 (scm_init_async): Moved initialization for scm_gc_async and
978 scm_gc_vcell to gc.c. Moved initialization of scm_asyncs here
981 * async.h (scm_gc_async): Not globally visible any more.
983 * gc.c (scm_gc_stats): Made callable even from within regions
986 (scm_gc_end): Eliminate the hardcoding of the marking of the
987 scm_gc_async from the gc core.
989 (scm_init_storage): Don't initialize the scm_asyncs list here.
990 This is now done in asyncs.c.
992 (scm_gc_vcell): Moved here from async.c.
994 (gc_async): Renamed from scm_gc_async, moved here from async.c
997 (gc_async_thunk): Renamed from scm_sys_gc_async_thunk and moved
1000 (mark_gc_async): New hook function for scm_after_gc_c_hook.
1002 (scm_init_gc): Added initialization of scm_gc_vcell and
1003 gc_async. Further, add mark_gc_async to scm_after_gc_c_hook.
1005 * init.c (scm_boot_guile_1): scm_init_gc requires asyncs to be
1008 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1010 * gc.c (scm_igc): Removed commented code that once was intended
1011 to unprotect struct types with no instances.
1013 * root.h (scm_type_obj_list): Removed.
1015 2000-06-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
1017 * async.c (scm_init_async): Switch to standard way of smob
1020 2000-06-21 Michael Livshin <mlivshin@bigfoot.com>
1022 * guile-doc-snarf.in: use cut instead of sed, that's much much
1023 faster. also, don't call basename more than needed. and, to gain
1024 a couple of microseconds more, don't call cat needlessly. (thanks
1027 2000-06-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
1029 * guile-snarf.awk.in, guile-snarf.in, snarf.h: Rename SCM__I to
1030 SCM_SNARF_INIT_START, SCM__D to SCM_SNARF_DOC_START, SCM__S to
1031 SCM_SNARF_DOCSTRING_START and SCM__E to SCM_SNARF_DOCSTRING_END.
1033 2000-06-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1035 * eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
1036 #include "libguile/fluids.h".
1038 * eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
1039 SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
1041 * root.h (scm_top_level_lookup_closure_var,
1042 scm_system_transformer): Removed. (It's no sense in having the
1043 *variable* be a "fluid".)
1045 * root.c (mark_root): Removed marking of
1046 s->top_level_lookup_closure_var and s->system_transformer.
1048 * modules.c (scm_selected_module): the_module is now a fluid.
1050 2000-06-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1052 * gc.h, tags.h: Be kind to compilers which must see hash signs in
1053 column 0. (Thanks to Ian Grant.)
1055 * numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
1056 the long_long type. (Thanks to Bernard Urban.)
1058 2000-06-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1060 * gc.c, gc.h (scm_default_init_heap_size_1,
1061 scm_default_min_yield_1, scm_default_init_heap_size_2,
1062 scm_default_min_yield_2, scm_default_max_segment_size): New global
1063 variables. Can be customized by the application before booting
1064 Guile. (We might want to be able to control these parameters
1065 dynamically through the "options interface" in the future, but
1066 note that that is additional functionality. Here we're giving
1067 default values which the environment variables can override.)
1069 * list.c (scm_cons_star): Updated comment.
1071 * smob.h: Changed comments for scm_make_smob_type and
1072 scm_make_smob_type_mfpe, warning that the latter might be
1073 deprecated in a future release.
1075 2000-06-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1077 * list.[ch] (scm_cons_star/cons*): Renamed from
1078 scm_list_star/list*.
1080 * list.[ch] (scm_list_star/list*): Provided as a deprecated alias
1081 for scm_cons_star/cons*.
1083 * gc.c (scm_protect_object): Updated comment.
1085 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX): Removed.
1087 * tags.h (SCM_UNPACK_CAR, SCM_NDOUBLE_CELLP): Removed.
1089 2000-06-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1091 * init.c, init.h (scm_initialized_p): Renamed from `initialized'
1094 * gdbint.c (gdb_print): Print warning instead of calling scm_write
1095 if Guile isn't yet initialized.
1097 * print.c (scm_current_pstate, scm_make_print_state): Simplified
1098 tests, using the assumption that Guile has been initialized.
1100 Sun Jun 18 14:45:21 2000 Greg J. Badros <gjb@cs.washington.edu>
1102 * print.c (s_scm_current_pstate): Do not segfault when the
1103 print_state_pool is unitialized in `current-pstate', and better
1104 verify its state before altering it in scm_make_print_state().
1106 2000-06-18 Michael Livshin <mlivshin@bigfoot.com>
1108 * scmsigs.c (s_scm_sigaction): guard the SIGIOT case with an
1109 #ifdef -- it's missing on at least one platform. (thanks to
1112 2000-06-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1114 * list.c (list*): Added documentation from common-list.scm.
1116 2000-06-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
1118 * gc.c (scm_unprotect_object): The reference count is guaranteed
1119 to be a positive number.
1121 2000-06-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1123 * eval.c: Updated comment above scm_map.
1125 2000-06-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1127 * gc.c (scm_protect_object): Avoid looking up the object handle
1129 (scm_unprotect_object): Abort if scm_unprotect_object is called on
1130 an unprotected object.
1132 2000-06-14 Michael Livshin <mlivshin@bigfoot.com>
1134 * gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
1137 2000-06-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1139 * socket.c (scm_getsockopt): Changed type for `optlen' from int to
1141 (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
1142 Ditto for `tmp_size'.
1143 (scm_addr_buffer_size): Changed type from int to size_t.
1145 * random.c: #include <string.h>. (Needed by memcpy.)
1147 * guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
1148 indicating stdin, instead of "" and don't reset ARGC. This is a
1149 workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
1150 it is correct, and perhaps even better.
1152 2000-06-14 Gary Houston <ghouston@arglist.com>
1154 * scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not
1155 defined, add SA_RESTART to the sigaction flags correctly
1156 (thanks to Dale P. Smith).
1158 2000-06-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1160 * strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
1162 * net_db.c (scm_resolv_error): Only use macro NETDB_INTERNAL if
1163 defined. It isn't on sgi irix 5.3. (Thanks to Bill Schottstaedt.)
1165 * Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
1167 2000-06-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1169 * fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
1170 since read and write buffers are allocated by `malloc'.
1172 * Makefile.am: Removed old test code.
1174 * gh_test_c.c, gh_test_repl.c: Removed.
1176 2000-06-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1178 * iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2
1181 * inet_aton.c (inet_aton): Cast init value for `cp'.
1183 * ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
1186 * symbols.c (scm_intern_obarray_soft,
1187 scm_sysintern0_no_module_lookup): Cast `name' to unsigned char ptr
1188 in calls to scm_strhash.
1190 * strports.c (st_resize_port): Substituted SCM_UCHARS for
1192 (st_write): Cast argument to strncpy to char ptr.
1193 (scm_mkstrport): Substituted SCM_ROUCHARS for SCM_ROCHARS.
1194 (scm_strport_to_string): Cast argument to scm_makfromstr to char
1197 * ports.c (scm_ungetc): Cast value to unsigned char ptr before
1198 storing in putback_buf.
1199 (scm_unread_string): Substituted SCM_ROCHARS for SCM_ROUCHARS.
1201 * ioext.c (s_scm_read_line): Cast result of call to
1202 scm_do_read_line to unsigned char ptr.
1204 * gdbint.c (SEND_STRING): Cast argument to char pointer.
1206 * fports.c (fport_flush): Declare `ptr' as unsigned char (was
1209 * Makefile.am (DOT_DOC_FILES): List doc-files explicitly. (We
1210 shouldn't use Make rules which aren't supported by most Make
1212 (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h". (We don't
1213 want these dependencies recorded, since they would get bogus
1214 relative paths; libguile.h is only used in gh.h and guile.c.)
1215 (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
1216 (guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
1217 (modinclude_HEADERS): Removed kw.h.
1219 * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
1220 (The preprocessor might insert spaces before the identifier.)
1222 * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
1223 Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
1225 * smob.h (scm_smobfuns): Removed deprecated type.
1227 * smob.c, smob.h (scm_newsmob): Removed deprecated function.
1228 (Replaced by `scm_make_smob_type'.)
1230 * keywords.c (scm_tc16_kw): Removed deprecated type.
1231 (Replaced by scm_tc16_keyword.)
1233 * kw.h: Removed deprecated header file.
1235 * evalext.c (serial-map): Removed deprected alias for scm_map.
1236 (Has been replaced by `map-in-order'.)
1238 * ramap.c (serial-array-copy!, serial-array-map!): Removed
1239 depracted aliases. (Replaced by `array-copy-in-order!' and
1240 `array-map-in-order'.)
1242 2000-06-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1244 * gc.h (SCM_VALIDATE_CELL): Rewritten.
1245 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
1246 SCM_SET_CELL_OBJECT): Use new version of SCM_VALIDATE_CELL.
1247 (Thanks to Han-Wen Nienhuys.)
1249 2000-06-10 Michael Livshin <mlivshin@bigfoot.com>
1251 * guile-doc-snarf.in: don't pipe the CPP output right into sed --
1252 write it to the temp file first and check the CPP return code.
1253 (I introduced this bug earlier, and this probably caused people
1254 with non-GNU C preprocessors to get empty *.x files and not to
1255 have the build fail right away...).
1257 * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
1258 -- at least my libc5-based Linux system doesn't define SIGSYS.
1260 2000-06-08 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1262 * snarf.h, guile-snarf.awk.in, guile-snarf.in: Replaced snarf
1263 markers with identifiers (SCM__I, SCM__D, SCM__S, SCM__E).
1264 (Thanks to Bernard Urban.)
1266 2000-06-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1268 * modules.c (scm_system_module_env_p): Fixed detection of system
1271 2000-06-06 Marius Vollmer <mvo@zagadka.ping.de>
1273 * scmsigs.c (scm_sigaction): Silently ignore setting handlers for
1274 `program error signals' because they can't currently be handled by
1277 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1279 * procs.h (SCM_SET_SUBRF): Added.
1281 * procs.c (scm_make_subr_opt): Don't assign to SCM_SUBRF, use
1282 SCM_SET_SUBRF instead. Thanks to Bernard Urban for the bug
1285 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1287 * gc.h (SCM_CARLOC, SCM_CDRLOC): Don't take the address of a SCM
1290 * sort.c (scm_sorted_p, scm_merge, scm_merge_list_x,
1291 scm_merge_list_step): Don't take the address of SCM_CAR. Use
1292 SCM_CARLOC instead. Thanks to Bernard Urban for the bug report.
1294 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1296 * boolean.h (SCM_TRUE_P): Removed, as people might use it as a
1297 replacement for !SCM_FALSEP.
1299 * backtrace.c (display_error_body), boolean.h (SCM_BOOLP), gc.c
1300 (scm_unhash_name), gh_data.c (gh_module_lookup), load.c
1301 (scm_primitive_load), print.c (scm_simple_format), procs.c
1302 (scm_procedure_documentation), procs.h (SCM_TOP_LEVEL), ramap.c
1303 (scm_array_fill_int), scmsigs.c (scm_sigaction), stacks.c
1304 (narrow_stack, scm_make_stack, scm_stack_id), symbols.c
1305 (scm_string_to_obarray_symbol), throw.c (scm_catch,
1306 scm_lazy_catch, scm_ithrow), unif.c (scm_make_uve, scm_array_p,
1307 scm_array_set_x, scm_bit_set_star_x, scm_bit_count_star),
1308 validate.h (SCM_VALIDATE_BOOL_COPY, SCM_VALIDATE_PROC): Replace
1309 uses of SCM_TRUE_P (x) with SCM_EQ_P (x, SCM_BOOL_T).
1311 2000-06-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1313 * eval.c (scm_badformalsp): New static function.
1314 (SCM_CEVAL): Check arguments for procedure-with-setter closures.
1315 (Thanks to Keisuke Nishida.)
1317 The major reason for Guile's slow loading speed has been the fact
1318 that a chain of Scheme level procedures has been evaluated for
1319 every top-level symbol lookup during the first pass through the
1322 The following is a kludge which I suggested four years ago, and
1323 which I've repeatedly suggested since. Personally, I've never
1324 been bothered by Guile's slow loading speed, so I thought I would
1325 let someone else do it...
1327 But since the new environments will be included first in
1328 Guile-1.5, I thought it would make people happy to get the kludge
1331 * modules.c: Added #include "libguile/vectors.h";
1332 Added #include "libguile/hashtab.h";
1333 Added #include "libguile/struct.h";
1334 Added #include "libguile/variable.h";
1335 Capture Scheme level `module-make-local-var!' to be used in the
1336 standard eval closure.
1337 (scm_standard_eval_closure): New primitive.
1339 * modules.h (scm_standard_eval_closure): Declare.
1341 * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
1342 instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
1344 * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
1345 standard eval closures.
1347 * variable.c: Code layout fixes.
1349 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1351 * Makefile.am: Added LIBS line to libpath which accidentally
1352 disappeared in the change of 2000-06-01.
1353 (Thanks to Dale P. Smith.)
1355 2000-06-03 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1357 * scmsigs.c (scm_segfault): Removed. (Was probably added by
1358 mistake since it is not mentioned in ChangeLog.)
1360 * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
1361 avoid compiler warnings in gcc. (Does this work for other
1364 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1366 * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
1368 (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
1369 SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1. It's not correct to take
1370 the address of these expressions since they use SCM_VALIDATE_CELL.
1371 (Thanks to Bernard Urban.)
1373 * dynl.c: Changed #include <ltdl.h> --> #include
1374 "libltdl/ltdl.h". (Thanks to Bill Schottstaedt.)
1376 2000-06-01 Craig Brozefsky <craig@red-bean.com>
1378 * Makefile.am: libguile_la_LDFLAGS gets -version-info args
1379 from GUILE-VERSION definition of LIBGUILE version. Added to
1380 libpath.h definitions for guileversion and libguileversion which
1381 both get their values from GUILE-VERSION definition.
1383 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1385 * numbers.h (SCM_BIGP): Don't use SCM_SMOB_PREDICATE in header
1386 file: Code using numbers should not be required to include
1389 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1391 * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
1392 mit-pthreads.c, mit-pthreads.h: Deleted.
1394 * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]: Drop
1395 references to deleted files and fsu/mit thread support in
1398 2000-05-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1400 * hooks.c (symbol_name, scm_create_hook): Restored the original
1401 behaviour of scm_create_hook. Changing it was bad as Carl
1402 R. Witty has pointed out.
1404 * gc.c (scm_init_gc): We can still rely on scm_create_hook to
1407 2000-05-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
1409 * gc.c (scm_init_gc): Protect scm_after_gc_hook, since this will
1410 soon not be done by scm_create_hook any longer.
1412 * hooks.c (make_hook, print_hook, scm_create_hook,
1413 scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
1414 SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
1415 scm_make_hook_with_name), init.c (scm_boot_guile_1): Hooks no
1416 longer have names. As an intermediate solution, the name
1417 predicate is emulated via object properties, but use of this
1418 feature is deprecated.
1420 * hooks.h (scm_free_hook): Removed, as it is never defined.
1422 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1424 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
1425 Un-deprecated since otherwise user code can't determine whether a
1426 number fits into an inum any longer. The names should be changed
1429 * numbers.c (scm_big2inum): Eliminated use of SCM_UNEGFIXABLE.
1431 * tags.h (SCM_UNPACK_CAR): Deprecated.
1433 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1435 * filesys.h (SCM_OPDIRP), fluids.h (SCM_FLUIDP, SCM_FLUID_NUM),
1436 fports.h (SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP), hooks.h
1437 (SCM_HOOK_ARITY), keywords.h (SCM_KEYWORDP, SCM_KEYWORDSYM),
1438 numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
1439 Replace SCM_UNPACK_CAR appropriately. Don't access cells via
1440 SCM_{SET}?C[AD]R unless they are known to be cons cells.
1442 * gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
1443 init_heap_seg): Remove unused struct member variable 'valid'.
1445 2000-05-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
1447 * fports.c (fport_write), ports.c (scm_markstream, scm_port_mode,
1448 scm_print_port_mode), ports.h (SCM_OPPORTP, SCM_OPINPORTP,
1449 SCM_OPOUTPORTP, SCM_INPUT_PORT_P, SCM_OUTPUT_PORT_P, SCM_OPENP),
1450 procs.h (SCM_CLOSCAR), unif.h (SCM_ARRAY_NDIM, SCM_ARRAY_CONTP),
1451 variable.h (SCM_VARIABLEP): Replace SCM_UNPACK_CAR
1454 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1456 * gc.c (free_list_length), hash.c (scm_hasher), macros.c
1457 (scm_macro_type), objects.c (scm_class_of), options.c
1458 (scm_options), print.c (scm_iprin1), strports.c (st_seek), throw.c
1459 (SCM_LAZY_CATCH_P): Replace SCM_UNPACK_CAR appropriately.
1461 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1463 * eval.c (scm_macroexp, SCM_CEVAL, scm_force), tags.h: Replace
1464 SCM_UNPACK_CAR with SCM_CELL_TYPE or SCM_CELL_WORD_0.
1466 * eval.c (scm_force): Add documentation.
1468 * eval.c (scm_force, scm_cons_source): Don't access cells via
1469 SCM_{SET}?C[AD]R unless they are known to be cons cells.
1471 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1473 * strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
1474 (SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP): Deprecated.
1476 * gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT): Removed #ifdef
1477 nosve #endif conditionally compiled code.
1479 2000-05-23 Michael Livshin <mlivshin@bigfoot.com>
1481 * gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
1483 2000-05-22 Michael Livshin <mlivshin@bigfoot.com>
1485 * guile-doc-snarf.in: put the preprocessed file through sed to
1486 trim all lines to 1024 chars. I hope it doesn't break anybody's
1487 sed. we'll see. (note: this is lossy trimming, i.e. the spill
1488 isn't wrapped around but actually chopped off. this seemed to me
1489 safe because the current snarfer doesn't understand multi-line
1490 cookies anyway. in the long term, it would be nice not to depend
1491 on AWK for anything.)
1493 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
1494 the previous change to this macros, after deciding to torture the
1497 2000-05-21 Michael Livshin <mlivshin@bigfoot.com>
1499 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
1500 the yucky, ugly and nasty conditional compilation back. sorry,
1501 but it was either that or requiring GAWK to build Guile.
1502 (lots of places): removed the code that implemented the old GC
1505 * init.c (scm_boot_guile_1): removed the code conditioned on
1506 !GUILE_NEW_GC_SCHEME.
1508 * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
1510 * gc.c (scm_protect_object, scm_unprotect_object): change the
1511 implementation to more efficient (at least in the time complexity
1512 sense). the calls should now also be thread-safe -- I suspect
1513 that people expect them to be. (thanks to Han-Wen Nienhuys)
1514 (lots of places): removed the code that implemented the old GC
1517 * hashtab.c (scm_hash_fn_create_handle_x): add missing
1518 SCM_REALLOW_INTS before return. I really wonder about the
1519 possible interactions between hashtables, threads & GC. it
1520 doesn't look healthy at all.
1522 2000-05-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1524 * unif.c (scm_bit_count): Fixed the parameter checks. Thanks to
1527 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1529 * __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_): Added as a new
1530 debug option to verify all accesses to cells actually access
1531 objects on the heap.
1533 * gc.h (SCM_VALIDATE_CELL): Added. Only performs validation if
1534 SCM_DEBUG_CELL_ACCESSES is set to 1.
1536 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
1537 SCM_SET_CELL_OBJECT): Use SCM_VALIDATE_CELL to check every cell
1540 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1542 * gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs,
1543 gh_scm2floats, gh_scm2doubles): Change !SCM_NIMP to SCM_IMP.
1545 * gc.c (scm_cellp): Fixed and simplified.
1547 * throw.c (JBJMPBUF, SETJBJMPBUF, SCM_JBDFRAME, SCM_SETJBDFRAME,
1548 make_jmpbuf, scm_init_throw): Now using double cells to represent
1549 jump buffers when using debug extensions.
1553 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1555 * gh.h gh_data.c gh_funcs.c (gh_new_procedure*, gh_chars2byvect,
1556 gh_shorts2svect, gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect,
1557 gh_doubles2dvect, gh_doubles2scm, gh_define, gh_lookup,
1558 gh_module_lookup): Accept const pointers as parameters.
1560 * gh.h gh_data.c (gh_int2scmb): Deprecated.
1562 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1564 * __scm.h (SCM_DEBUG_REST_ARGUMENT): Renamed from
1565 SCM_DEBUG_REST_ARGUMENTS in order to clarify that we don't test
1566 the actual arguments in the list, but rather the rest argument as
1567 a list of arguments.
1569 * validate.h (SCM_VALIDATE_REST_ARGUMENT): Added.
1571 * async.c (scm_noop), eval.c (scm_map, scm_for_each), list.c
1572 (scm_list_star, scm_append, scm_append_x), ports.c
1573 (scm_close_all_ports_except), ramap.c (scm_array_map_x,
1574 scm_array_for_each), regex-posix.c (scm_make_regexp), stacks.c
1575 (scm_make_stack), strings.c (scm_string_append), struct.c
1576 (scm_make_struct, scm_make_vtable_vtable): Validate rest arguments.
1578 * dynl.c (DYNL_GLOBAL, sysdep_dynl_link, kw_global, sym_global,
1579 scm_dynamic_link, scm_init_dynamic_linking), dynl.h
1580 (scm_dynamic_link): Removed possibility to pass flags to
1581 scm_dynamic_link, as it had no effect anyway.
1583 * filesys.c (scm_fcntl): Made single optional rest argument into
1584 a standard optional argument.
1586 * hooks.c (scm_run_hook): A list of rest arguments is never
1589 * list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
1590 strings.c (scm_string_append): Don't perform half-hearted checks
1591 to see whether the rest argument forms a proper list any more, use
1592 SCM_VALIDATE_REST_ARGUMENTS instead.
1594 * ports.c (scm_close_all_ports_except): Accept empty list of rest
1597 * posix.c (scm_convert_exec_args), print.c (scm_simple_format):
1598 Simplify verification of rest argument.
1600 * stacks.c (scm_make_stack), stacks.h (scm_make_stack), throw.c
1601 (ss_handler, handler_message): Make first mandatory rest argument
1602 of scm_make_stack into a standard mandatory argument.
1604 * unif.c (scm_transpose_array, scm_enclose_array,
1605 scm_array_in_bounds_p), unif.h (scm_transpose_array,
1606 scm_enclose_array, scm_array_in_bounds_p): Make first mandatory
1607 rest argument into a standard mandatory argument.
1609 2000-05-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
1611 * __scm.h: Added SCM_DEBUG as default debug option. (Thanks to
1612 Keisuke Nishida for the suggestion.) Added debug option
1613 SCM_DEBUG_REST_ARGUMENTS.
1615 * eval.c (scm_map, scm_for_each): Make sure all lists have the
1616 same length. Also, removed redundant parameter checks.
1618 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1620 * Makefile.am: Let 'make clean' remove *.x and *.doc files.
1622 * __scm.h: Improved explanation of giving options to make.
1624 * __scm.h (SCM_DEBUG_TYPING_STRICTNESS), tags.h
1625 (SCM_STRICT_TYPING, SCM_DEBUG_TYPING_STRICTNESS): Renamed
1626 SCM_STRICT_TYPING to SCM_DEBUG_TYPING_STRICTNESS and moved the
1627 corresponding declaration and comment to __scm.h.
1629 * _scm.h (errno), gc.h (SCM_CELLPTR, SCM_PTR_LT), numbers.c
1630 (scm_remainder, scm_modulo), numbers.h (SCM_SRS, SCM_MAKINUM,
1631 SCM_INUM): Removed conditionally compiled code for Turbo C.
1633 * gdbint.c (gdb_maybe_valid_type_p): Eliminated call to scm_tag.
1634 That check can be assumed to be redundant except for very rare
1635 conditions that actually indicate broken heap data.
1637 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1639 * numbers.c (scm_logcount, scm_integer_length): Reordered
1642 2000-05-15 Gary Houston <ghouston@arglist.com>
1644 * stime.c (scm_strftime): don't reset TZ if zone is an empty
1645 string. append a "0" to the zone for TZ.
1647 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
1649 * numbers.c (scm_logbit_p, scm_bit_extract): Reordered dispatch
1652 (scm_bit_extract): Fixed handling of bignums.
1654 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>

1664 (scm_tc16_flo, scm_tc_flo, scm_tc_dblr, scm_tc_dblc): Wrapped
1665 deprecated code between #if (SCM_DEBUG_DEPRECATED == 0) #endif.
1667 * fports.c (scm_fport_buffer_add), ports.c (scm_input_port_p,
1668 scm_output_port_p), print.c (scm_get_print_state), validate.h
1669 (SCM_VALIDATE_CHAR): Replace use of deprecated macros
1670 SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
1671 SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
1673 2000-05-14 Gary Houston <ghouston@arglist.com>
1675 * stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
1676 TZ environment variable so that the %Z format returns the zone
1677 from the input vector instead of the system default.
1679 from Keisuke Nishida:
1680 * fports.c (scm_setvbuf): minor docstring fix.
1681 * ports.h (scm_generic_fgets): obsolete prototype deleted.
1683 2000-05-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
1685 * __scm.h: Added new section for debugging options.
1687 (SCM_DEBUG_DEPRECATED): If 1, no deprecated code is included to
1688 help developers to get rid of references to deprecated code.
1690 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,
1691 SCM_FIXABLE, SCM_FLOBUFLEN): These macros are no longer provided
1692 as part of the interface and are marked as deprecated in the
1695 * numbers.c (scm_make_real, scm_make_complex): Inlined the
1696 corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
1699 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,
1700 SCM_REAL, SCM_IMAG, SCM_REALPART, scm_makdbl, SCM_SINGP,
1701 SCM_NO_BIGDIG, SCM_NUM2DBL, scm_dblproc): Deprecated.
1703 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1705 * gc.h (scm_cell, SCM_CELL_WORD, SCM_CELL_OBJECT,
1706 SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT): Scheme cells now consist
1707 of two scm_bits_t values instead of two SCM values, because it is
1708 legal for cell entries to hold values that are not scheme objects.
1710 (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
1711 Use SCM_SETC[AD]R to modify contents of pairs.

1715 * numbers.c (IS_INF, isfinite): Added FIXME comment.
1717 (scm_abs, scm_magnitude): Make these two independent of each
1718 other. scm_abs now reports an error if given a complex argument.
1720 (scm_istr2flo, scm_integer_p). Use SCM_REAL_VALUE instead of
1721 SCM_REALPART if the object is known to be real.
1723 (scm_init_numbers): No need to use SCM_NEWREAL macro for speed
1726 * numbers.h (SCM_SINGP): Set to 0 instead of SCM_BOOL_F.
1728 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1730 * eq.c (scm_eqv_p): Separate handling of real and complex

1734 gh_scm2doubles), hash.c (scm_hasher), ramap.c (scm_array_fill_int,
1735 ramap_rp, scm_array_map_x), random.c (vector_scale,
1736 vector_sum_squares), unif.c (scm_make_uve, scm_array_p,
1737 scm_array_set_x): Use SCM_REAL_VALUE instead of SCM_REALPART if
1738 the object is known to be real. Use SCM_COMPLEXP instead of
1739 deprecated SCM_CPLXP. Use SCM_INEXACTP instead of deprecated
1742 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1744 * numbers.c: No need to include unif.h.
1746 (IS_INF): Returned to old test for now: x == x + 1 will not work
1747 for large numbers due to rounding errors.
1748 Thanks to Kalle Olavi Niemitalo.
1750 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1752 * numbers.c (scm_divbigdig): Removed outdated comment.
1754 (scm_number_to_string, scm_string_to_number, scm_number_p,
1755 scm_real_p, scm_integer_p, scm_inexact_p, scm_gr_p, scm_leq_p,
1756 scm_geq_p, scm_make_rectangular, scm_make_polar,
1757 scm_inexact_to_exact): Added comments.

1761 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1763 * numbers.c (IS_INF): The new test is x == x + 1. The old test
1764 x == x/2 did not work for zero values. Thanks to Han-Wen Nienhuys
1767 (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
1768 scm_num2long, scm_num2long_long, scm_num2ulong): Reordered
1771 2000-05-09 Marius Vollmer <mvo@zagadka.ping.de>
1773 * scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
1774 SIGILL and SIGBUS signals. These signals are not continuable and
1775 must be handled for real right away.
1777 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1779 * numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,
1780 scm_real_part, scm_imag_part, scm_magnitude,
1781 scm_inexact_to_exact): Reordered dispatch sequence.
1783 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1785 * feature.c: No need to include "libguile/smob.h"
1787 (scm_loc_features, features, scm_add_feature, scm_init_feature):
1788 Removed variable 'scm_loc_features' as a pointer to the SCM value
1789 holding the features list. Using variable 'features' instead,
1790 which holds the interned pair. Thus, SCM_SETCDR can be used
1791 instead of pointer trickery.
1793 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1795 * alist.c (scm_acons): Use SCM{_SET}?_CELL_OBJECT as long as a
1796 cell is not known to be a valid pair.
1798 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1800 * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1): Removed
1801 ASRTSYNTAX. Using SCM_ASSYNT instead.
1803 (scm_m_body): Don't create a redundant cons cell.

1807 (bodycheck): Removed.
1809 * stacks.c (stack_depth, read_frame, read_frames): Removed
1810 redundant calculation of size, minimized some variable scopes.
1812 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1814 * pairs.c (scm_cons, scm_cons2): Use SCM{_SET}?_CELL_OBJECT as
1815 long as a cell is not known to be a valid pair.
1817 (scm_pair_p): Eliminated redundant SCM_IMP test.
1819 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1821 * eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,
1822 scm_deval_args): Eliminated redundant SCM_IMP tests.
1824 * hashtab.c (scm_ihashx, scm_sloppy_assx, scm_delx_x), weaks.c
1825 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
1826 scm_make_doubly_weak_hash_table): Fixed critical sections.
1827 Thanks to Keisuke Nishida.
1829 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1831 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
1832 Fixed some goto-related initialization bugs (introduced by me).
1834 2000-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
1836 * numbers.h (SCM_INUM0): Uses SCM_MAKINUM instead of SCM_PACK.
1838 * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj): Removed.
1840 (DYNL_FILENAME, DYNL_HANDLE): Use SCM_CELL... macros instead of
1843 (SET_DYNL_HANDLE): Added.
1845 (scm_dynamic_object_p): Simplified.
1847 (scm_dynamic_unlink, scm_dynamic_func): Changed comment. Deliver
1848 better error message when accessing unlinked dynamic objects.
1849 Eliminated call to get_dynl_obj.
1851 2000-05-03 Marius Vollmer <mvo@zagadka.ping.de>
1853 * scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
1854 be an array of function pointers instead of being a pointer to an
1855 array returning function. Thanks to Kalle Olavi Niemitalo!
1857 2000-05-03 Dirk Herrmann <D.Herrmann@tu-bs.de>
1859 * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
1860 (scm_divbigbig, scm_divbigint): Don't return zero any more to
1861 indicate that a division has a remainder, return SCM_UNDEFINED
1862 instead. It is improbable that anyone actually used these
1863 functions outside of numbers.c. For this reason and due to the
1864 change in behaviour the functions are static now. Thus, if
1865 surprisingly there are users of these functions they will at least
1868 * numbers.c: Removed #ifdef SCM_BIGDIG #endif in those functions,
1869 that already have a clean dispatch order. Note: SCM_BIGDIG is
1872 * numbers.c (scm_inexact_p): Simplified.
1874 * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
1875 scm_product, scm_num2dbl, scm_angle): Reordered dispatch
1876 sequence, thereby fixing some comparisons of SCM values with
1879 * numbers.c (scm_divide): Division by zero of inums leads to an
1880 error now. (Formerly, an infinite number was returned.)
1882 Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
1883 if a division has a remainder.
1885 2000-05-02 Gary Houston <ghouston@arglist.com>
1887 * Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).
1889 2000-05-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
1891 * numbers.c (scm_logtest, scm_division): Reordered dispatch
1892 sequence, thereby fixing some comparisons of SCM values with
1895 * numbers.h (scm_makdbl): Mark as deprecated at the point of

1904 (ramap_rp, scm_array_map_x), random.c (scm_random,
1905 scm_random_uniform, scm_random_normal_vector_x, scm_random_exp),
1906 struct.c (scm_struct_ref), unif.c (scm_array_to_list): Replace
1907 call to scm_makdbl with a call to scm_make_real or
1908 scm_make_complex, depending on whether the imaginary part is known
1911 2000-05-01 Gary Houston <ghouston@arglist.com>
1913 * scmsigs.c: fix the definition of orig_handlers for the case
1914 that HAVE_SIGACTION is not defined (thanks to
1915 Kalle Olavi Niemitalo).
1917 * Makefile.am: remove include_HEADERS (was libguile.h)
1918 libguile.h: moved to top level directory.
1920 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1922 * numbers.c (SCM_SWAP): Moved to the top of the file to allow for
1925 * numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,
1926 scm_logxor): Reordered dispatch sequence, thereby fixing some
1927 comparisons of SCM values with integer constants.
1929 * number.c (scm_logtest): Removed some redundant SCM_{N}?IMP
1932 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1934 * numbers.c (scm_quotient, scm_remainder): Removed code that was
1935 conditionally compiled based on BADIVSGNS. BADIVSGNS does not
1936 occur anywhere else throughout guile.
1938 * numbers.c (scm_quotient): Fixed parameter number in error
1941 * numbers.c (scm_remainder): Reordered dispatch sequence.
1943 2000-04-25 Gary Houston <ghouston@arglist.com>

1951 (suggested by Jost Boekemeier).
1953 2000-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1955 * pairs.c (cxrs, scm_init_pairs): Simplify initialization of
1958 * procs.c (scm_init_iprocs), procs.h (scm_subr, scm_iproc,
1959 scm_dsubr, scm_init_iprocs): Removed.
1961 * procs.h (SCM_SUBRF, SCM_DSUBRF): Access the cell words
1962 directly instead of casting a cell to a C struct.
1964 2000-04-22 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1966 Better modularization of GC extensions through new C level GC
1969 * weaks.c (scm_weaks_prehistory): New function: Add

1992 (scm_before_gc_c_hook, scm_before_mark_c_hook,
1993 scm_before_sweep_c_hook, scm_after_sweep_c_hook,
1994 scm_after_gc_c_hook): New C level hooks.
1995 (scm_after_gc_hook): New Scheme level hook.
1996 (scm_gc_sweep): Moved scanning of weak vectors to weaks.c.
1997 (scm_igc): Moved initialization of scm_weak_vectors and the call
1998 to scm_guardian_gc_init to respective module.

2021 (DEFS): Added. automake adds -I options to DEFS, and we don't
2023 Removed all -I options except for the root source directory and
2024 the root build directory.
2026 * numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG
2027 instead of SCM_ASSERT (0, ...). (Some compilers will complain
2028 about control reaching end of function otherwise, and, besides,
2029 the new code is not less clear.)
2031 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Added
2032 calls to malloc debugging functions.

2045 documentation strings.
2047 * numbers.c (scm_exact_p, scm_odd_p, scm_even_p, scm_abs,
2048 scm_quotient): Reordered dispatch sequence to first handle
2049 immediates, second handle bignums and finally handle generic
2050 functions respectively signal wrong type arguments. Hopefully
2051 this will allow for easier separation when goops is integrated.
2053 2000-04-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
2055 * gc.c (which_seg): Use SCM2PTR to convert a non immediate SCM
2056 variable into a pointer to a heap cell.
2058 * gc.c (scm_mark_locations, scm_cellp, init_heap_seg,

2064 SCM_UNDEFINED instead.
2066 * weaks.c (scm_make_weak_vector): Fix assignment of zero to a
2067 vector element. (Still to be improved)
2069 2000-04-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
2071 * eval.c (undef_cell): Removed, replaced by:
2073 (undef_object): Added to replace undef_cell.

2083 symbolic names for the tc3 type codes.
2085 * eval.c (scm_m_define, SCM_CEVAL, SCM_APPLY): Remove redundant
2088 * eval.c (scm_eval_args, scm_deval_args, SCM_CEVAL): Made the
2089 access of the struct vcell element explicit.

2094 scm_struct_free_entity): Use `scm_must_free' instead of `free'.
2096 * procs.c (scm_make_subr_opt): Tell scm_must_realloc that we're
2097 realloc:ing scm_subr_table ("what" instead of "who").
2099 * numbers.c (scm_adjbig): Ditto.
2101 Tue Apr 18 08:22:41 2000 Greg J. Badros <gjb@cs.washington.edu>
2103 * validate.h: Do not cast to (unsigned) in SCM_VALIDATE_INUM_RANGE
2104 when testing high-end of the range. Mikael Djurfeldt noticed this
2105 anomaly -- thanks Mikael!
2107 2000-04-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
2109 * unif.c (l2ra): Don't eliminate the call to scm_array_set_x
2110 itself, as was done in the previous 'patch'. (Thanks to Radey
2113 2000-04-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
2115 * options.c (scm_options), read.c (recsexpr): Remove redundant

2125 unsigned long and signed long arrays and clarified the way the
2126 access is performed.
2128 * ramap.c (scm_array_map_x, raeql), read.c (scm_lreadr), stacks.c

2412 separate loop after processing all the currently known live
2413 guardians, so as to not introduce order dependencies (thanks to
2414 Gary Houston). note that the order problems are still there if
2415 some guardians are themselves zombies, but that's a sick case that
2416 I'm not going to worry about.
2417 also, make another outer loop to process zombified

2609 (scm_sloppy_memv, scm_sloppy_member, scm_delv_x, scm_delete_x,
2610 scm_delv1_x, scm_delete1_x), scmsigs.c (scm_sigaction): Use
2611 SCM_FALSEP and SCM_TRUE_P to compare SCM values against #f and
2614 * list.c (scm_listify): Use SCM_UNBNDP to test for an unbound
2617 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2619 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread,
2620 scm_make_mutex, scm_make_condition_variable): Cast data to
2621 scm_bits_t in SCM_SET_CELL_WORD and SCM_NEWSMOB macros.
2623 * coop.c (coop_create): Set `specific' field, not `data' to NULL.
2625 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2627 * smob.h (SCM_NEWSMOB, SCM_NEWSMOB2, SCM_NEWSMOB3, SCM_SMOB_DATA,
2628 SCM_SET_SMOB_DATA, SCM_TC2SMOBNUM, SCM_SMOBNUM): To access smob
2629 data, use SCM_{SET_}?CELL_TYPE or SCM_{SET_}?WORD_[1-3].
2631 Note that this implies that smob data has always to be passed as
2632 values of type scm_bits_t.
2634 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2636 * threads.c (scm_init_threads): Pass 0 size to scm_make_smob_type
2637 for scm_tc16_thread. As the current COOP threads are written, GC
2638 is not supposed to manage storage for threads.
2640 * error.c (scm_error): Don't try to throw an error if
2641 scm_gc_heap_lock is true.
2643 * coop.c (coop_finish): New function. Called at exit.
2644 (coop_aborthelp): Free thread structures when threads die.
2645 Finished LinuxThreads compatibility support => COOP threads now
2646 mesh with LinuxThreads.
2648 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread):
2649 Changed SETCDR --> SET_CELL_WORD_1.
2651 * coop-threads.c (scheme_launch_thread): Set word 1 of handle to 0
2654 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2656 * boolean.h (SCM_TRUE_P): New macro.
2658 * boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP), pairs.h
2659 (SCM_NULLP, SCM_NNULLP): Use SCM_EQ_P to compare SCM values.
2661 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2663 * continuations.h (SCM_CONTREGS, SCM_SET_CONTREGS): New macros to
2664 access continuation data.
2666 (SCM_SETJMPBUF): Deprecated. Use SCM_SET_CONTREGS instead.
2668 (SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE, SCM_BASE, SCM_SEQ,
2669 SCM_DFRAME): Use SCM_CONTREGS instead of SCM_CHARS to access
2672 * continuations.c (scm_make_cont), init.c (start_stack),
2673 root.c (scm_internal_cwdr): Use SCM_SET_CONTREGS instead of
2676 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2678 * symbols.h (SCM_LENGTH, SCM_SETLENGTH): Access the length field
2679 of strings and symbols by using SCM_{SET_}?CELL_WORD_0.
2681 (SCM_CHARS, SCM_UCHARS, SCM_SETCHARS): Use SCM_{SET_}?CELL_WORD_1
2682 to access the char * field of strings and symbols.
2684 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2686 * gc.h (SCM_NEWCELL, SCM_NEWCELL2): Use SCM_SET_CELL_TYPE to set
2687 the type entry of a new cell. Added a comment about things to
2688 remember when updating the list of free cells.
2690 (SCM_FREEP, SCM_MARKEDP): Use SCM_CELL_TYPE to access the type
2693 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2695 * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR): Use
2696 SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT. This change implies that
2697 with strict type checking enabled these macros will only work if
2698 given valid SCM parameters.
2700 (SCM_GCCDR): Moved to tags.h.
2702 * tags.h (SCM_GCCDR): Moved here from pairs.h.
2704 2000-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
2706 * tags.h (SCM2PTR, PTR2SCM): Moved to gc.h.
2708 * pairs.h (scm_cell, SCM_CELLPTR, SCM_CELL_WORD*, SCM_CELL_OBJECT*,
2709 SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*, SCM_CELL_TYPE,
2710 SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK, SCM_PTR_GT,
2711 SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC, SCM_NEWCELL,
2712 SCM_NEWCELL2): Moved to gc.h.
2714 (SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR, SCM_SETAND_CDR,
2715 SCM_SETOR_CAR, SCM_SETOR_CDR): Moved to gc.h. These names should
2716 be changed, though, since the macros are not only pair related.
2720 * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,
2721 SCM_CELL_OBJECT*, SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*,
2722 SCM_CELL_TYPE, SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK,
2723 SCM_PTR_GT, SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC,
2724 SCM_NEWCELL, SCM_NEWCELL2, SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR,
2725 SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR): Moved here from
2728 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2730 * tags.h (SCM_STRICT_TYPING): New macro that, if defined,
2731 activates strict compile time type checking for variables of
2733 (SCM, SCM_PACK, SCM_UNPACK): Define according to whether
2734 SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
2735 (SCM_EQ_P): Defined as a macro equivalent for eq?.
2737 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2739 * tags.h (SCM_POINTERS_MUNGED): Removed.
2741 * gc.c (scm_gc_sweep, init_heap_seg): Removed use of
2742 SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
2744 2000-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
2746 * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
2747 SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
2748 SCM_SET_CELL_TYPE): Added a set of low level macros for accessing
2750 (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
2752 * procs.h, procs.c: Instead of SCM_{SET_}?CELL_WORD[12], use the
2753 newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
2755 2000-03-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2757 * tags.h: Disabled definition of SCM_VOIDP_TEST.
2759 Defining SCM as void * introduces problems which haven't been
2760 handled yet. Developers who work with these issues can enable it
2761 in their working copies.
2763 Disabling this definition exposes a set of newly introduced and
2764 older misuses of types which causes warning messages during
2765 compilation. We'll fix this successively.
2767 * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
2768 in order to obtain a value of type SCM.
2769 (scm_cellp): Updated with new changes to scm_mark_locations.
2771 * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
2773 * continuations.c (scm_make_cont): Removed cast of size_t into
2776 * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
2778 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2780 * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for
2781 shifting, not constant. Thanks to Dale P. Smith.
2783 * numbers.c (scm_sum, scm_difference): Don't test a SCM value
2784 for being less than zero. Decode it to a C value first. Again,
2787 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2789 * numbers.h, ramap.c, struct.h, vectors.h: Don't use SCM2PTR for
2790 non scheme values. If raw data is stored in SCM variables, it has
2791 to be accessed using SCM_UNPACK until a better solution is found.
2793 2000-03-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2795 * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
2796 pointer-arithmetic induced by the SCM_PACK/UNPACK change.
2798 * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
2800 * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
2802 * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
2804 * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
2806 * async.c, __scm.h: Removed lots of the old async click logic. It
2807 is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
2808 __scm.h. Let's try this out and dump the old code after the
2809 threads reorganization.
2810 (set-tick-rate, set-switch-rate): Conditionally removed.
2812 2000-03-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2814 * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
2815 made SCM values into pointers. This turned an arithmetic
2816 computation of the address of the vcell into a pointer-arithmetic
2817 one, thereby screwing up marking of structs.
2818 Bugfix 2: Removed incompletely introduced loop variable `j' used
2819 when protecting the tail array of a struct.
2821 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2823 * struct.h (SCM_STRUCT_DATA): Don't cast SCM values to pointers.
2825 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2827 * symbols.h, symbols.c (scm_strhash): Declare the string
2828 parameter as constant, since it is not modified.
2830 * symbols.c (scm_intern_obarray_soft,
2831 scm_sysintern0_no_module_lookup): Can now pass constant strings
2832 to scm_strhash without need for casting.
2834 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2836 * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS): Don't cast SCM
2837 values to pointers. Use SCM2PTR instead.
2839 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2841 * async.c (scm_set_tick_rate, scm_set_switch_rate): Don't unpack
2842 results of SCM_INUM.
2844 2000-03-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2846 * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
2847 GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
2848 GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
2850 * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
2851 min_yield_fraction, min_yield, adjust_min_yield): Renamed from
2852 SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
2853 gc_trigger, adjust_gc_trigger.
2855 * gc.c (alloc_some_heap): Further improvement of minimal heap size
2857 (SCM_MAX): New macro.
2858 (scm_freelist_t): New field: collected_1. Previous amount of
2860 (gc_sweep_freelist_finish): Trigger based on two last values of
2861 freelist->collected to avoid unnecessary allocation due to
2863 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
2864 Adjusted to 45000 cells, 40% and 40%. Gives quick startup
2865 without extra heap allocation.
2867 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2869 * numbers.h (SCM_MAKINUM): The parameter to SCM_MAKINUM should
2870 already be a C value. No need to unpack it.
2872 * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t
2873 if we know it fits into an inum.
2875 * ramap.c (ramap_rp): An scm_tc7_[ui]vect object does point to a
2876 field of long values. In contrast, SCM_VELTS accesses a field of
2879 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2881 * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
2883 (scm_gc_yield_1): New variable: Holds previous yield. Used to
2884 make better judgements.
2885 (gc_sweep_freelist_finish): Inserted explanation of use of
2888 * print.h, stacks.h, options.c, options.h: Changed C++
2891 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2893 * tags.h (SCM2PTR, PTR2SCM): Use SCM_PACK / SCM_UNPACK correctly.
2895 * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
2896 SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS): Use SCM_PACK /
2897 SCM_UNPACK / SCM2PTR correctly.
2899 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2901 * gc.c (adjust_gc_trigger): Improved documentation.
2902 (alloc_some_heap): Since gc_trigger is used against
2903 freelist->collected, this is the value which should be used to
2904 predict minimum growth.
2906 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2908 * eval.h: Fix mixup of packed/unpacked SCM values. (Thanks
2909 Thien-Thi Nguyen for the patch.)
2911 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2913 * numbers.c (scm_ash): Fixed typing problems with the second
2914 parameter and added some documentation. (Thanks Thien-Thi Nguyen
2915 for indicating the problem.)
2917 2000-03-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2919 * gc.c, gc.h (scm_gc_yield): New variable.
2920 (adjust_gc_trigger): Use scm_gc_yield.
2921 (alloc_some_heap): Use scm_gc_yield instead of
2922 scm_gc_cells_collected.
2924 * coop-threads.c: Addd #include "root.h", #include "strings.h".
2926 * debug.c: Added #include "root.h". (Thanks to Thien-Thi Nguyen.)
2928 * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
2929 trigger adjustmeant: Take yield (freed cells) for all freelists
2931 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
2932 to 50000 cell heap with 45% trigger.
2933 (scm_gc_cells_collected): Reintroduced.
2934 (SCM_HEAP_SIZE): New macro.
2935 (scm_gc_sweep): Reintroduced correct computation of
2936 scm_cells_allocated.
2937 (scm_freelist_t): Corrected commentary for field `cluster_size':
2938 Clustersize counts objects, not cells; New member
2939 `clusters_allocated'.
2941 2000-03-19 Michael Livshin <mlivshin@bigfoot.com>
2943 * *.[hc]: add Emacs magic at the end of file, to ensure GNU
2946 2000-03-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2948 * threads.h: Added #include "libguile/throw.h". (Thanks to
2951 2000-03-18 Michael Livshin <mlivshin@bigfoot.com>
2953 * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
2954 names, anyone got any better ones?)
2956 * gc.h: (typedef struct scm_freelist_t) remove from here.
2958 * gc.c: (CELL_UP, CELL_DN) made these macros take additional
2959 parameter (the span).
2960 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
2961 (typedef struct scm_freelist_t) moved here from gc.h, it had no
2962 business being externally visible.
2963 (typedef struct scm_heap_seg_data_t) renamed from
2964 scm_heap_seg_data, to be style-compliant.
2965 (scm_mark_locations) if the possible pointer points to a
2966 double-cell, check that it's properly aligned.
2967 (init_heap_seg) align double-cells properly, work with the
2968 assumption that the segment size divides cleanly by cluster size.
2969 (round_to_cluster_size) new function.
2970 (alloc_some_heap, make_initial_segment) use round_to_cluster_size
2971 to satisfy the new init_heap_seg invariant.
2973 2000-03-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
2975 * _scm.h: Don't include async.h everywhere...

3030 2000-03-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3032 * gc.c, gc.h: Cleanup of the change of 2000-03-15.
3033 Cluster sizes are now independent of GC trigger values.
3034 GUILE_GC_TRIGGER_n can now specify a relative trigger value:
3035 A negative integer gives fraction of total heap size in percent.
3036 (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
3038 * init.c (scm_boot_guile_1): Introduced new variable
3039 GUILE_MAX_SEGMENT_SIZE; New environment variable names:
3040 GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
3041 GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
3043 2000-03-16 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3045 * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
3046 freeing of segment work with the new GC scheme. (Thanks to
3047 Michael Livshin.) Oops, also happened to make GUILE_NEW_GC_SCHEME
3048 the default, but I'll let this change stay in CVS Guile since this
3049 code is not expected to contain serious bugs.
3051 2000-03-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3053 * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
3055 (scm_free_list_length): New procedure (GUILE_DEBUG).
3056 Fixed a small but serious bug introduced by the previous change.
3058 * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
3059 loop and declare as register.
3061 * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
3064 Wed Mar 15 08:27:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3066 * fluids.c: Docstring patch from Keisuke Nishida. Some
3067 reindentation, too, and a couple formals renamed. Should
3068 fluid-set! return UNSPECIFIED instead of a value?
3070 Wed Mar 15 08:24:58 2000 Greg J. Badros <gjb@cs.washington.edu>
3072 * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
3073 generate the latter from the concrete listing of the former. Then
3074 make guile-procedures.txt depend on DOT_DOC_FILES instead of
3075 *.doc, so that rebuilding it works.
3077 Wed Mar 15 08:12:14 2000 Greg J. Badros <gjb@cs.washington.edu>
3079 * libguile.h: Include libguile/validate.h. Thanks Keisuke Nishida!
3081 * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
3082 with nothing and \n, respectively. Thanks Keisuke Nishida for
3083 noticing this problem.
3085 2000-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3087 * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
3088 new way of allocating heap. It makes Guile fast, but still
3091 * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
3092 allocating heap. The basic idea is to trigger GC every Nth
3093 allocated cell and grow heap when free list runs out. The scheme
3094 has been extended so that GC isn't triggered until all remaining
3095 cells are used. The implementation is also prepared for
3096 development in the direction of POSIX threads.
3098 * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
3099 SCM_EXPHEAP should return half of the heap size.
3101 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3103 The following change to init.c is only enabled if Guile was
3104 configured with --enable-guile-debug.
3106 * init.c (scm_i_getenv_int): New function.
3107 (scm_boot_guile_1): Use the environment variables
3108 GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
3109 they exist. (This may be replaced by a Scheme level mechanism in
3112 * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
3113 scm_assoc. (Thanks to Keisuke Nishida.)
3115 2000-03-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3117 * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
3118 scm_nil, scm_t. (Thanks to Keisuke Nishida.)
3120 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3122 * init.c (scm_boot_guile_1): Use same initial segment size for
3123 1-word and 2-word segments. Having the smaller size causes Guile
3124 to GC too often. Obviously something needs to be done to allow
3125 for a smaller 2-word segment without this to happen. (The amount
3126 of heap for each type should be automatically adapted to the
3127 application somehow.)
3129 [Almost all of these changes should be documented in the NEWS
3132 * gc.h (scm_freelist_t): New type.
3134 * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
3136 * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
3137 all of Guile basics fits into one segment and there suitable room
3139 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
3141 (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
3142 Freelists now contains information about object span, cells
3143 collected and amount of cells in heap segments belonging to the
3145 (scm_heap_size, scm_gc_cells_collected): Removed.
3147 * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
3149 * Makefile.am (libguile_la_LDFLAGS): Bumped library version
3152 * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
3153 numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
3154 rewrite of handling of real and complex numbers.
3155 (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
3156 removed along with the support for floats. (Float vectors are
3159 * tags.h (scm_tcs_bignums): Removed.
3160 (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
3161 Use SCM_BIGSIGN(x) to test for sign!
3162 (scm_tc16_big): The new bignum type.
3163 (SCM_REAL_PART, SCM_IMAG_PART): Removed.
3165 * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
3166 (scm_makdbl): Deprecated.
3167 (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
3168 (SCM_SINGP): Deprecated.
3170 (SCM_INEXP, SCM_CPLXP): Deprecated.
3171 (SCM_INEXACTP, SCM_COMPLEXP): New macros.
3172 (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
3173 SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
3174 (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
3175 for doubles and complex numbers.
3176 (SCM_REAL_VALUE): New selector for doubles.
3177 (scm_double_t, scm_complex_t): New types.
3180 * numbers.c (scm_floprint, scm_floequal): Removed.
3181 (scm_print_real, scm_print_complex, scm_real_equalp,
3182 scm_complex_equalp): New functions.
3184 * unif.c (scm_makflo): Removed.
3186 * smob.h (SCM_SMOB_PREDICATE): New macro.
3187 (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
3188 SCM_RETURN_NEWSMOB3): New macros.
3190 1999-11-21 Michael Livshin <mlivshin@bigfoot.com>
3192 The following changes implement primitive support for double cells
3193 (i.e. four-word cells) and change the representation of some
3194 things to multi-cells instead of cons+malloc. (Applied and
3197 * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
3198 (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
3199 multi-cell access macros (used by the ones below).
3200 (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
3203 * gc.c (scm_freelist2): multi-cell freelists.
3204 (inner_map_free_list): map_free_list, parameterized on ncells.
3205 "nn cells in segment mm" was misleading for ncells > 1; changed to
3206 "objects". still print cells too, though.
3207 (scm_map_free_list): rewritten using inner_map_free_list.
3208 (scm_check_freelist): get freelist as parameter, since now we have
3210 (scm_debug_newcell2): multi-cell variants of
3212 (scm_gc_for_newcell): take ncells and freelist pointer as
3214 (scm_gc_mark): add case for tc7_pws (procedures with setters are
3216 (scm_gc_sweep): don't free the float data, since it's not malloced
3218 (init_heap_seg): didn't understand what n_new_objects stood for,
3219 so changed to n_new_cells.
3220 (make_initial_segment): new function, makes an initial segment
3221 according to given ncells.
3222 (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
3224 * numbers.c (scm_makdbl): no malloc'ing needed, so the
3225 {DEFER,ALLOW}_INTS thing removed.
3227 * numbers.h (struct scm_dbl): changed to represent a double cell,
3228 with the number in the second half.
3230 * dynwind.c: changed the wind-guards representation to double
3233 * procs.c, procs.h: changed the procedure-with-setter representation
3236 * async.c, async.h: made async representation a double cell.
3238 * dynl.c: made dynamic_obj representation a double cell.
3240 2000-03-13 Gary Houston <ghouston@arglist.com>
3242 * ports.c (flush_void_port): renamed to flush_port_default.
3243 (end_input_void_port): renamed to end_input_default.
3245 * init.c (scm_standard_stream_to_port): create a void port instead
3246 of opening /dev/null if the standard file descriptors are bad.
3247 advantages: no portability problems, doesn't waste a file descriptor,
3248 simplifies the code (thanks to Marius for the idea).
3250 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
3252 * void ports: make reading from a void port give EOF instead of
3254 * ports.c (s_scm_sys_make_void_port): modified docstring.
3255 (fill_input_void_port): new proc.
3256 (scm_init_ports): set up fill_input_void_port.
3257 * ports.c (scm_port_non_buffer): new proc.
3258 (scm_void_port): call scm_port_non_buffer.
3260 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
3261 which was incorrectly appended.
3263 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3265 * guile-doc-snarf.in: Don't use absolute path for `sed'. (Note
3266 that we can't use autoconf for this. Autoconf itself relies on
3267 the existence of `sed' somewhere on your path.) (Thanks to Dirk
3270 2000-03-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3272 * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
3273 EXTRA_libguile_la_SOURCES.
3275 * iselect.h: Always declare scm_internal_select.
3277 * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
3278 end. Also let scm_internal_select be a real function also when
3281 * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
3283 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3285 * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
3286 SCM_ASYNC_TICK. (This is a preparation for POSIX threads support,
3287 and kind of an experiment: Will this cause problems?)
3289 Sun Mar 12 13:26:30 2000 Greg J. Badros <gjb@cs.washington.edu>
3291 * Makefile.am: Added *.doc to DISTCLEANFILES.
3293 2000-03-12 Gary Houston <ghouston@arglist.com>
3295 * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
3296 the fdes is valid before doing anything else. check that
3297 the file descriptor supports the modes required.
3298 (scm_fport_buffer_add): don't throw an error if fstat doesn't
3299 work: just use the default buffer size.
3301 * throw.c: change an outdated comment about scm_internal_catch
3302 BODY: it doesn't take a jumpbuf arg.
3304 * init.c (scm_standard_stream_to_port): install a handler in case
3305 scm_fdes_to_port throws an error. don't check here whether the
3306 file descriptor is valid, since scm_fdes_to_port will do that.
3307 set the revealed count depending on whether the port got the
3308 standard file descriptor.
3309 (stream_body_data): new type.
3310 (stream_body, stream_handler): new procs.
3312 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3314 * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
3315 Renamed from SCMWORD.
3317 * tags.h (SCM_NCELLP): Removed (SCMWORD).
3319 * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
3321 * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
3322 feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,
3323 hash.c, keywords.h, macros.c, numbers.c, numbers.h, objects.c,
3324 objects.h, options.c, pairs.h, ports.c, ports.h, print.c,
3325 procs.h, ramap.c, read.c, smob.c, smob.h, srcprop.h, stacks.c,
3326 stacks.h, strports.c, struct.c, struct.h, tag.c, tags.h,
3327 throw.c, unif.c, unif.h, variable.h, vectors.h, weaks.c,
3328 weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
3329 SCM_ASSCM, SCM_ASWORD, SCM_CARW).
3331 * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
3333 * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
3334 tags.h: Fixed copyright notices.
3336 * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
3338 2000-03-12 Marius Vollmer <mvo@zagadka.ping.de>
3340 * init.c (scm_standard_stream_to_port): Check whether the file
3341 descriptor is valid and substitute "/dev/null" when not.
3343 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3345 * coop-defs.h (struct timespec): Conditionally defined.
3347 * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
3350 * readline.c (match_paren): Bugfix: First arg to select is not
3351 number of descriptors but the number of the highest descriptor +
3354 This is a preliminary attempt at a cleanup of the threads support
3355 code. It moves things to better places, makes arguments more
3356 consistent with the POSIX API (which is used in GNOME's glib), and
3357 adds new functionality.
3359 * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
3361 * coop-defs.h (scm_mutex_trylock): New macro: alias for
3363 (scm_cond_init): Changed definition to
3364 coop_new_condition_variable_init.
3366 * coop.c: #include <errno.h>
3367 (coop_timeout_qinsert): Moved here from iselect.c
3368 (coop_new_mutex_init, coop_new_condition_variable_init): New
3369 functions. The strange names are temporary. Use scm_mutex_init
3370 and scm_cond_init instead.
3371 (coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
3372 is ANSI C, but should we check for individual error codes in
3374 (coop_condition_variable_timed_wait_mutex): New function.
3375 (coop_key_create, coop_setspecific, coop_getspecific,
3376 coop_key_delete): New functions.
3378 * iselect.c (coop_timout_qinsert): Moved to coop.c
3380 2000-03-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3382 * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
3383 SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
3385 * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
3388 * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
3389 SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
3390 proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
3392 * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
3395 2000-03-11 Dale P. Smith <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
3397 * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
3398 scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
3399 logical functions from SCM.
3401 (logand, logior, logxor, logtest, logbit?): Extended scheme
3402 logical functions to use bignums from SCM.
3404 (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
3405 lognot from using bignums.
3407 Thu Mar 9 11:33:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3409 * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
3410 eliminating some warnings.
3412 * unif.c, strports.c, print.c, options.c: Fix some warnings on
3415 * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
3416 what the scm_return_first* functions do.
3418 2000-03-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
3420 * libguile/*.[ch]: make a distinction between SCM as a generic
3421 name for a Scheme object (now a void*), and SCM as 32 bit word for
3422 storing tags and immediates (now a long int). Introduced
3423 SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
3424 code in the process: arbiter.c (use macros), unif.c (scm_array_p),
3426 Wed Mar 8 10:15:59 2000 Greg J. Badros <gjb@cs.washington.edu>
3428 * numbers.c: Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
3429 various logXXX primitives. Thanks Eric Moore!
3431 Tue Mar 7 08:05:22 2000 Greg J. Badros <gjb@cs.washington.edu>
3433 * run-test, remaining-docs-needed: Added these scripts. The
3434 second one is only temporary until the docstring additions are
3435 complete. run-test may best live on, but is here mostly for
3436 convenience and awareness for now.
3438 * hash.c: Docs, minor cleanup patch from Dirk Herrman.
3440 Thu Mar 2 16:06:58 2000 Greg J. Badros <gjb@cs.washington.edu>
3442 * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
3443 displaying the expected type. Use SCM_LISTn in a couple places
3444 instead of scm_cons-ing by hand.
3446 * __scm.h: Added SCM_ASSERT_TYPE macro.
3448 * validate.h, scm_validate.h: Added the former, as a renamed
3449 version of the latter with SCM_ASSERT_TYPE used in
3450 SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
3452 * Makefile.am: Rename scm_validate.h to validate.h.
3454 * *.c, *.h: Include validate.h, not scm_validate.h (old name's
3455 prefix was superfluous).
3457 Thu Mar 2 15:33:12 2000 Greg J. Badros <gjb@cs.washington.edu>
3459 * hashtab.c: Improved documentation for lots of functions. Added
3460 handwritten docs for `hash-fold'.
3462 Thu Mar 2 15:13:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3464 * list.c: Added hand-written docs for `del{q,v,ete}1!'.
3466 Thu Mar 2 12:38:30 2000 Greg J. Badros <gjb@cs.washington.edu>
3468 * list.c: Moved append docs to append! Thanks Dirk Hermann. Also,
3469 added append docs from R4RS.
3471 * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
3472 Thanks Dirk Hermann!
3474 * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
3475 deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
3477 * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
3478 Drop use of SCM_P for function prototypes... assume an ANSI C
3479 compiler. Thanks Dirk Hermann!
3481 Sat Feb 19 12:20:12 2000 Greg J. Badros <gjb@cs.washington.edu>
3483 * ports.c: Made `set-port-column!' and `set-port-line!' each
3484 return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
3485 that caused a seg fault. Also fixed `set-port-column!'s
3486 docstring. Thanks Han-Wen Nienhuys for finding the bug!
3488 Sun Feb 13 19:11:42 2000 Greg J. Badros <gjb@cs.washington.edu>
3490 * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
3491 regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
3492 strings.c, variable.c: Added lots of documentation, cleaned up
3493 some existing documentation. Occasionally changed formal params
3494 to match docs. Also folded an #ifdef into the inners of a
3495 primitive instead of having two copies of the primitive
3496 (`get-internal-real-time', from stime.c)
3498 Sun Feb 13 18:12:19 2000 Greg J. Badros <gjb@cs.washington.edu>
3500 * ports.c: Added docs for primitives missing them. Written by
3503 Sun Feb 13 09:40:36 2000 Greg J. Badros <gjb@cs.washington.edu>
3505 * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
3506 just execing guile-func-name-check. Thanks Michael Livshin!
3508 Thu Feb 10 11:43:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3510 * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
3511 dead code. Patch from Michael Livshin.
3513 * guile-doc-snarf.in: Tweak to work with Sun/HP sh. Patch from
3516 2000-02-09 Gary Houston <ghouston@arglist.com>
3518 * init.c (scm_init_standard_ports): when stdout is a tty, make the
3519 current-output-port unbuffered by default. this is less confusing
3520 for interactive use. it was line-buffered because of a
3521 performance problem with unbuffered ports, but I think it will be
3524 2000-02-08 Gary Houston <ghouston@arglist.com>
3526 * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
3529 * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
3530 HAVE_TZNAME are defined, use an empty string instead of giving two
3531 spurious compile-time errors.
3533 Tue Feb 8 13:57:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3535 * ports.c: Doc patches from Richard Kim. Pasted from MIT Scheme.
3538 Mon Feb 7 09:07:31 2000 Greg J. Badros <gjb@cs.washington.edu>
3540 * macros.c: Doc patches from Richard Kim. Pasted from scm.texi.
3542 Sun Feb 6 20:26:21 2000 Greg J. Badros <gjb@cs.washington.edu>
3544 * pairs.c: Doc patches from Richard Kim. Pasted from MIT Scheme
3545 (which is GNU GPL'd).
3547 2000-01-31 Gary Houston <ghouston@arglist.com>
3549 * strings.h: don't use SCM_P. don't include <string.h>.
3550 * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
3552 * strings.c (scm_string_ref): make the 2nd argument compulsory.
3553 previously it defaulted to zero for no good reason that I can see.
3554 use a local variable for SCM_INUM (k). replace
3555 SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
3557 (scm_makfromstr): cosmetic changes.
3559 (scm_string): Accept only chars in the list, not strings, for
3560 conformance to R5RS (particularly for list->string, which is
3561 supposed to be the inverse of string->list.) remove
3562 SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
3563 scm_makstr handles the cell allocation. when reporting wrong-type
3564 arg, don't report the position as 1.
3566 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
3568 2000-01-29 Gary Houston <ghouston@arglist.com>
3570 * posix.c (scm_pipe): rewrote the docstring.
3572 * filesys.c (scm_select, retrieve_select_type, get_element,
3573 fill_select_type, set_element): modified so that Scheme
3574 "select" tests port buffers for the ability to provide input
3575 or accept output. Previously only the underlying file descriptors
3576 were checked. Rewrote the docstring.
3578 Thu Jan 27 10:14:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3580 * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
3581 from Gregg Reynolds. Thanks Gregg!
3583 Thu Jan 27 09:59:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3585 * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
3586 adding "x" prefix to the line so that guile-func-name-check
3587 doesn't complain unnecessarily.
3589 Wed Jan 26 17:33:52 2000 Greg J. Badros <gjb@cs.washington.edu>
3591 * throw.c: Factor out an #ifdef/#else/#endif choice more finely
3592 for maintainability.
3594 * strop.c: Documentation added by Gregg A. Reynolds. Pasted in
3597 Wed Jan 26 10:02:11 2000 Greg J. Badros <gjb@cs.washington.edu>
3599 * tag.c: Added doc for `tag', but mark as deprecated since Mikael
3600 suggests removing tag.c altogether (and using a new `class-of'
3603 * strings.c: Added documentation from Gregg A. Reynolds. Edited
3604 a bit by me to use FOO instead of @var{foo} and to have the
3605 summary come before preconditions on input. Also dropped trailing
3608 * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
3609 function with scm_make_subr_opt w/ last arg of 0 so it is not
3610 visible at the Scheme level. Mikael says that this is the right
3611 thing because the first arg to the proc is the guts of a compiled
3612 closure and shouldn't be exposed to the Scheme level.
3614 Tue Jan 25 17:15:47 2000 Greg J. Badros <gjb@cs.washington.edu>
3616 * sort.c: typo in comment fixed.
3618 * keywords.c: Added documentation.
3620 * guardians.c: Added documentation (could be better).
3622 * gc.c: Added docs for gc-set-debug-check-freelist.
3624 * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
3626 * boolean.c: Added docs for `not', `boolean?' (by hand).
3628 Tue Jan 25 13:28:56 2000 Greg J. Badros <gjb@cs.washington.edu>
3630 * random.c: Added documentation, from SLIB page:
3631 http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
3633 Mon Jan 24 17:50:20 2000 Greg J. Badros <gjb@cs.washington.edu>
3635 * variable.c, version.c: Added documentation, written by hand
3636 since I could not find anything already written that was
3639 2000-01-23 Gary Houston <ghouston@arglist.com>
3641 * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
3642 not defined (thanks to Richard Y. Kim).
3644 Thu Jan 20 13:00:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3646 * Makefile.in: Removed, this is auto-generated.
3648 Thu Jan 20 11:33:47 2000 Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
3650 * list.c: Put some variable initialization code at the point of
3651 declaration; Added a comment for list*; Formatting changes.
3653 * load.c: use SCM_NNULLP to make sure the end of a list is not
3656 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3658 * backtrace.c (scm_display_error_message): Bugfix: Don't use
3659 result of scm_list_p as C boolean.
3660 (scm_display_error_message, scm_set_print_params_x): Use new
3661 validation macros. (Thanks to Dirk Herrmann.)
3663 * net_db.c (scm_resolv_error): Cast result from hstrerror.
3665 * strports.c (st_end_input): Inserted parenthesis to get operator
3668 * list.h (scm_init_list): Removed SCM_P around prototypes.
3670 * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
3671 filesys.c, posix.c: Converted docstrings to ANSI C format and
3672 escaped " occurring inside string literals.
3674 Tue Jan 18 13:21:08 2000 Mikael Djurfeldt <mdj@r11n07-s.pdc.kth.se>
3676 * posix.c (scm_mknod): Escape " occuring inside docstring.
3678 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3680 * alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,
3681 evalext.c, filesys.c, gc.c, hash.c, hashtab.c, ioext.c,
3682 keywords.c, list.c, load.c, macros.c, net_db.c, numbers.c,

3686 symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
3687 weaks.c: Converted docstrings to ANSI C format.
3689 * filesys.c (scm_chmod), simpos.c (scm_system), version
3690 (scm_version), vports (scm_make_soft_port): Escape " occuring
3693 Mon Jan 17 11:41:22 2000 Greg J. Badros <gjb@cs.washington.edu>
3695 * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
3696 SCM_VALIDATE_LONG_COPY
3698 * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
3699 SCM_VALIDATE_INUM_COPY to let bigger numbers be used. Rename a
3700 couple of formal arguments (and fix their uses) to make arguments
3701 match the documentation.
3703 2000-01-14 <mstachow@alum.mit.edu>
3705 * Makefile.am: Augment path when running guile-doc-snarf so
3706 guile-func-name-check is found.
3708 Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
3710 * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
3711 def, not SCM_MAKINUM(def); thanks Janis Bzerins!
3713 Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3715 * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
3716 the way guile-1.3.4 worked, but #if 0 out the version using
3717 SCM_VALIDATE_INUM_COPY for stricter testing.
3719 Tue Jan 11 18:24:18 2000 Greg J. Badros <gjb@cs.washington.edu>
3721 * guile-doc-snarf.in: Use new $fullfilename for running
3722 guile-func-name-check, and put "$fullfilename" and "$filename" in
3723 quotes at uses to make sure re-splitting on whitespace does not
3724 occur (so filenames w/ embedded whitespace would work okay, though
3725 I sure hope we never have to deal with that! :-) ). Thanks to
3726 Mikael for pointing out the source_dir != build_dir was broken.
3728 Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
3730 * scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
3731 SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
3732 SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
3733 macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
3736 * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
3737 then return whether it's an open port (was validating that it was
3738 an open port -- this was a bug I introduced back in December, but
3739 my careful reading of diffs caught it).
3741 * numbers.c: Recombine the two conditional-compilation paths for
3742 all the log* primitives -- they were split based on #ifndef
3743 scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
3744 some bugs and inconsistencies in the two sets of implementations.
3745 (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
3747 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
3748 SCM_VALIDATE_INUM_COPY once where it should've been used.
3750 * fluids.c (scm_internal_with_fluids): Use
3751 SCM_VALIDATE_LIST_COPYLEN.
3753 * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
3754 this is questionable as it relaxes type safety, but other changes
3755 were useful and all SCM_NUM2LONG's should probably be
3756 revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
3758 * evalext.c: line-break change on 1 line.
3760 * eval.c (nconc2last): Takes a non-empty list as its first
3761 argument, not just a list.
3763 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
3765 Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3767 * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
3768 net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
3771 * symbols.c (scm_sysintern0): Fixed the function name in a
3772 scm_misc_error invocation.
3774 * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
3775 use scm_return_first to ward off latent GC bug that Mikael caught.
3777 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
3778 used before but should've been.
3780 2000-01-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3782 * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
3783 SCM_FUNC_CAST_ARBITRARY_ARGS.
3785 Tue Jan 11 13:44:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3787 * guile-func-name-check.in: Added this script to statically check
3788 #define FUNC_NAME, #undef FUNC_NAME in the source.
3790 * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
3791 redundant comment, semicolon; caught by new guile-func-name-check
3794 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
3795 Caught by new guile-func-name-check-script.
3797 * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
3799 * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
3800 guile-func-name-check.
3802 * guile-doc-snarf.in: Run guile-func-name-check on the file before
3805 Tue Jan 11 11:31:10 2000 Greg J. Badros <gjb@cs.washington.edu>
3807 * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
3808 port function take const void*, not void*.
3810 Tue Jan 11 11:18:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3812 * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
3813 strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
3814 SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
3815 consistency with the other macros dealing with immediate
3816 characters. (Similar to INT -> INUM change a week or so ago).
3818 Tue Jan 11 10:41:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3820 * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
3821 net_db.c, read.c, socket.c: Update error messages to use ~A for
3822 %s, ~S for %S to work with new `simple-format' format and be
3823 standardized better.
3825 * print.h, print.c (scm_simple_format): Added `simple-format'
3826 primitive. It's the old scm_display_error, with ARGS now a rest
3827 parameter, and the destination first instead of last (and a couple
3828 new capabilities inspired by `format' -- #t as destination means
3829 current-output-port, #f means return the formatted text as a
3832 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
3834 * backtrace.c (scm_display_error_message): Rewrote to use
3835 scm_simple_format() procedure.
3837 * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
3839 2000-01-09 Marius Vollmer <mvo@zagadka.ping.de>
3841 Finally applied the libltdl patch from Thomas Tanner, with slight
3844 * DYNAMIC-LINKING: Removed because it is obsolete.
3845 * dynl.c: Use ANSI prototypes.
3846 (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
3847 * scmconfig.h.in: Do not change, as it is automatically generated.
3849 1999-07-25 Thomas Tanner <tanner@ffii.org>
3851 * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
3853 * Makefile.am: likewise, add INCLTDL (libltdl headers) to
3854 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
3856 * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
3857 * guile.c: register preloaded modules
3858 * scmconfig.h.in: remove obsolete symbols
3860 2000-01-09 Gary Houston <ghouston@arglist.com>
3862 * These changes should make it unnecessary to call tzset from
3863 Scheme after modifying the TZ environment variable, even if the
3864 system date facilities cache the value.
3865 * stime.c (setzone, scm_localtime): added comments.
3866 (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
3867 (setzone): don't call tzset.
3868 (restorezone): call tzset only if HAVE_TZSET is defined.
3869 (scm_tzset): don't define if HAVE_TZSET not defined. Change the
3870 doc string to indicate that this procedure isn't likely to do
3872 (scm_localtime, scm_strftime, scm_mktime): call tzset if
3873 LOCALTIME_CACHE is defined.
3875 2000-01-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3877 * posix.c (scm_sync): Return SCM_UNSPECIFIED.
3879 2000-01-09 Gary Houston <ghouston@arglist.com>
3881 * eval.c: define scm_unbound_variable_key ('unbound-variable).
3882 scm_lookupcar1: throw an error with key 'unbound-variable instead
3883 of 'misc-error when an unbound variable is encountered.
3885 * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
3886 scm_symlink, scm_readlink, scm_lstat),
3887 posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
3888 scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
3890 simpos.c (scm_system),
3891 stime.c (scm_times, scm_strptime):
3892 move the HAVE_XXX feature tests out of the procedure bodies.
3893 don't use SCM_SYSMISSING.
3894 scm_validate.h (SCM_SYSMISSING): removed.
3895 error.h, error.c (scm_sysmissing): comment that this is deprecated.
3896 see ChangeLog entry for 1999-12-28.
3898 Sat Jan 8 19:52:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3900 * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
3902 Sat Jan 8 17:06:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3904 * backtrace.c: Fix spelling typo in a comment.
3906 * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
3907 text. Reformatted some of the expansions.
3909 Fri Jan 7 15:50:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3911 * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
3912 report the position of the argument.
3914 * error.h, error.c (scm_out_of_range_pos): Added this function to
3915 take extra "pos" argument, the position number of the errant
3918 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
3920 * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
3921 and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
3922 prefers that and I'm reasonably indifferent.
3924 Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
3926 * snarf.h: Factor out differences between C++ and non-C++ into
3927 SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
3928 definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
3929 Mikael's macros, below, but changed names and SCM_SNARFING no
3930 longer expands to include %%% -- that must appear in the argument
3931 so that the token appears at the call-site as a reminder).
3933 2000-01-07 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3935 * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
3936 snarf macro definitions.
3938 2000-01-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3940 * chars.c (scm_integer_to_char): Use Greg's nice
3941 SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
3944 Thu Jan 6 11:48:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3946 * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
3948 Thu Jan 6 11:22:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3950 * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
3951 instead of GUILE_PROC.
3953 Thu Jan 6 11:21:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3955 * alist.c: Do not report mismatch errors on some uses of `tmp' (do
3956 this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
3959 Thu Jan 6 09:54:33 2000 Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
3961 * scm_validate.h: Remove some redundant NIMP tests.
3963 * alist.c: minimize scope of the tmp variables, and initialize
3964 them when declared. The strange SCM_NIMP tests are replaced by
3965 SCM_CONSP tests that more closely reflect the intended semantics.
3966 However, we don't get a performance penalty here, because the
3967 SCM_CONSP test was performed by the ALISTCELL test anyway. * The
3968 extremely ugly use of ASRTGO macros was removed: The calls to
3969 ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
3970 label parameter that only exists when SCM_RECKLESS is not defined.
3971 This works, because ASRTGO itself is defined in a way that it only
3972 makes use of the label parameter if SCM_RECKLESS is not defined
3973 (shudder!). Does guile make at all use of the possibility to
3974 define SCM_RECKLESS? * Codesize is likely to be reduced, since
3975 instead of two calls to SCM_ASSERT performed by the ALISTCELL test
3976 we now only get one test.
3978 * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
3979 SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
3980 some variables in `list?'. Fix `reverse' and `reverse!'
3981 primitives to handle improper lists better.
3983 Wed Jan 5 11:24:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3985 * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
3986 macros and SCM_DEFINE macros to match GNU coding standards.
3988 Wed Jan 5 11:04:24 2000 Greg J. Badros <gjb@cs.washington.edu>
3990 * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
3992 Wed Jan 5 10:59:06 2000 Greg J. Badros <gjb@cs.washington.edu>
3994 * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
3995 better consistency with the names of other SCM_VALIDATE_ macros
3996 and better conformance to guile naming policy.
3998 Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
4000 * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
4001 SCM_VALIDATE instead of 1 to avoid a check on the argument (since
4002 it's not the actual name of the formal).
4004 * guile-snarf.awk.in: Do argument/number mismatch checking and
4005 print warnings in an Emacs compile-mode parseable format.
4007 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
4008 SCM_OUTOFRANGE as 3rd argument.
4010 * random.c: Fix argument/number mismatch (that I introduced :-( ).
4012 * __scm.h: Do not #define SCM_ARG* when snarfing;
4013 lets us distinguish between 1 and SCM_ARG1 when snarfing as only
4014 the former (using the number) requires the argument to match the
4015 formal in the current argument snarfing check.
4017 * snarf.h: Give new definition of SCM_ASSERT when in
4018 snarfing mode to output a lexically-identifiable sequence that the
4019 guile-snarf.awk script uses to verify argument/position matching.
4021 * ramap.c: Remove extraneous #undef FUNC_NAME.
4023 Wed Jan 5 08:36:38 2000 Greg J. Badros <gjb@cs.washington.edu>
4025 * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
4026 current version of the same functionality; it writes the .x output
4027 to stdout instead of directly into the file.
4029 Wed Jan 5 08:15:04 2000 Greg J. Badros <gjb@cs.washington.edu>
4031 * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
4032 posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
4033 redundant with the safer macros. Patch from Dirk Hermann applied
4034 by hand. Thanks Dirk!
4036 * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
4039 * ramap.c: whitespace change.
4041 Tue Jan 4 14:21:35 2000 Greg J. Badros <gjb@cs.washington.edu>
4043 * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
4044 removals from Dirk Hermann.
4046 * alist.c: Rename formals to match the parameter names in the
4047 documentation, updates to documentation. Thanks Dirk Hermann!
4049 2000-01-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4051 * eval.c (SCM_CEVAL): Reverse order of
4052 scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
4053 (Thanks to Brad Knotwell.)
4055 Mon Jan 3 08:30:02 2000 Greg Harvey <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
4057 * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
4060 * pairs.h: Added a comment about the need for the SCM_SETCAR in
4063 Mon Jan 3 08:25:19 2000 Greg J. Badros <gjb@cs.washington.edu>
4065 * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
4066 SCM_NIMP tests that were redundant are now eliminated. Patches
4067 from Dirk Hermann applied by hand.
