3 * print.c (scm_iprin1): write the ascii delete character as #\del
4 instead of '#\', so it can be read back. like in SCM.
6 2000-09-12 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
8 * symbols.c (duplicate_string): Don't try to copy the byte after
9 the string. This might not be `\0' and might even not be
12 2000-09-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
14 * symbols.c (scm_symbol_p): Eliminate redundant SCM_IMP test.
16 2000-09-12 Dirk Herrmann <D.Herrmann@tu-bs.de>
18 This patch unifies the formerly distinct ssymbol and msymbol types
19 to a common symbol type scm_tc7_symbol. The representation of the
20 new symbol type uses a double cell with the following layout:
21 <type/length, chars, raw_hash, prop-pair>, where the car of
22 prop-pair holds the symbol's function property and the cdr of
23 prop-pair holds the symbol's other properties. In the long run,
24 these properties will be removed. Then, the generic property
25 functions will be uses.
27 * eval.c (SCM_CEVAL), objects.c (scm_class_of), print.c
28 (scm_iprin1), tag.c (scm_tag): Use scm_tc7_symbol instead of
29 scm_tc7_ssymbol, scm_tc7_msymbol or scm_tcs_symbols.
31 * gc.c (scm_gc_mark): Mark the symbols property pair.
33 (scm_gc_sweep): There are no symbol slots any more.
35 * hash.c (scm_hasher): Instead of re-calculating the hash value
36 of a symbol, use the raw_hash value stored in the symbol itself.
38 * properties.h: Fix typo.
40 * strings.[ch] (scm_makstr, scm_makfromstr): The slot parameter
43 * symbols.[ch] (scm_strhash): Deprecated, replaced by a macro.
45 (scm_intern_obarray_soft): Made softness parameter unsigned.
47 (scm_string_hash): New function with the same functionality as
48 scm_strhash had before, except that the hash value is not adjusted
49 to a hash table size. Instead, the 'raw' hash value is returned.
51 * symbols.c (duplicate_string): New static convenience function.
53 (scm_sym2vcell, scm_sym2ovcell_soft, scm_intern_obarray_soft):
54 Renamed local variable from scm_hash to hash.
56 (scm_intern_obarray_soft): Don't check for a negative softness
57 any more. When generating symbol cells, use the new layout and
58 store the raw hash value in the symbol's cell.
60 (scm_symbol_to_string): Removed unnecessary cast.
62 (scm_intern_symbol, scm_unintern_symbol): Use scm_string_hash to
63 determine the hash values.
65 (msymbolize): Removed.
67 (scm_symbol_fref, scm_symbol_pref, scm_symbol_fset_x,
68 scm_symbol_pset_x, scm_symbol_hash): No need to distinguish
69 between different symbol types any more.
71 (scm_symbol_hash): Comment fixed.
73 * symbols.h: Comment about the distinction between ssymbols and
76 (SCM_SYMBOLP, SCM_ROSTRINGP): No need to distinguish between
77 different symbol types any more.
79 (SCM_PROP_SLOTS, SCM_SET_PROP_SLOTS): Added.
81 (SCM_SYMBOL_FUNC, SCM_SET_SYMBOL_FUNC, SCM_SYMBOL_PROPS,
82 SCM_SET_SYMBOL_PROPS, SCM_SYMBOL_HASH, SCM_SET_SYMBOL_HASH): Use
83 the new symbol cell layout.
85 * tags.h (scm_tc7_ssymbol, scm_tc7_msymbol, scm_tcs_symbols):
88 2000-09-12 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
90 * symbols.h (scm_gentemp): Declared.
92 * symbols.c (scm_gensym): Reimplemented. Now only takes one
93 optional argument which should be a *string*.
94 (scm_gentemp): Reimplemented and moved from boot-9.scm.
96 2000-09-10 Keisuke Nishida <kxn30@po.cwru.edu>
98 * modules.c: Use applicable smobs for eval closures instead of
99 compiled closures. Include "libguile/smob.h".
100 (f_eval_closure): Removed.
101 (scm_eval_closure_tag): New variable.
102 (scm_eval_closure_lookup): Renamed from eval_closure.
103 This function now takes a smob instead of a compiled closure.
104 (scm_standard_eval_closure): Create a smob instead of a compiled
106 (scm_init_modules): Initialize the eval closure type as a smob.
107 * modules.h (SCM_EVAL_CLOSURE_P): New macro.
108 (scm_eval_closure_tag, scm_eval_closure_lookup): Declare.
109 * symbols.c: Include "libguile/smob.h".
110 (scm_sym2vcell): Call scm_eval_closure_lookup directly if THUNK
113 2000-09-10 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
115 * Makefile.am (.x.doc): Bugfix: Added $(srcdir) to path in order
116 to allow for builds in separate tree.
118 * symbols.c (scm_gensym): Bugfixed my previous bugfix. (Thanks to
121 2000-09-10 Keisuke Nishida <kxn30@po.cwru.edu>

127 * environments.c (obarray_enter, obarray_retrieve,
128 obarray_remove): Make sure the hash value is a valid obarray
131 (obarray_enter, obarray_remove): Documentation improved.
133 (obarray_replace): Added.

138 2000-09-05 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
140 * symbols.c (scm_gensym): Check that argument is a symbol, not a
141 string. (Thanks to Ralf Mattes.)
143 2000-09-05 Marius Vollmer <mvo@zagadka.ping.de>
145 * init.c: Include "libguile/properties.h".
147 * gh_data.c (gh_scm2char): Validate that argument is a character.
149 2000-08-25 Dirk Herrmann <D.Herrmann@tu-bs.de>

157 * validate.h (SCM_VALIDATE_NUMBER_DEF_COPY): New macro.
159 2000-09-03 Marius Vollmer <mvo@zagadka.ping.de>
161 * Makefile.am (.x.doc): Pretend to create .doc files from .x files
162 and give explicit dependencies for .x files that depend on
163 generated files. This allows parallel builds. Thanks to Matthias
166 2000-08-27 Marius Vollmer <mvo@zagadka.ping.de>
168 * Makefile.am: Added gc_os_dep.c, properties.c, properties.x,
169 properties.h and properties.doc in the suitable places.
171 * init.h (scm_init_guile): New prototype.
173 * init.c (scm_init_guile, scm_init_guile_1): New interface for
174 initializing Guile that does return to the caller.
175 (scm_boot_guile_1): Use scm_init_guile_1 to initialize Guile.
176 Do not establish a catch-all, this is no longer needed.
178 * root.h (scm_properties_whash): New `sys_protect', used in
181 * throw.c (scm_ithrow): Perform catch-all handling here when no
182 suitable handler has been found. That way, we don't have to rely
183 on the user establishing a catch-all, which might be difficult for
184 him if he is using scm_init_guile instead of scm_boot_guile.
186 2000-09-03 Neil Jerram <neil@ossau.uklinux.net>
188 * vectors.c (scm_vector): Docstring: add @deffnx line for

197 incomplete Texinfo reference to a node in r4rs.texi.
198 (scm_symbol_to_string): Escape double quotes correctly within
201 * struct.c (scm_make_struct, scm_make_vtable_vtable): Docstring
202 fixes: `@dots' changed to `@dots{}'.
204 * strop.c (scm_substring_move_x): Docstring: add @deffnx lines for
205 substring-move-left! and substring-move-right!.

229 2000-09-03 Michael Livshin <mlivshin@bigfoot.com>
231 the following changes let Guile get rid of the `allocated' cell
234 * smob.c (scm_smob_prehistory): don't init the "allocated" smob
237 * tags.h (scm_tc16_allocated): removed.
239 * gc.h: removed now-obsolete comments about the `allocated' cell
241 (SCM_NEWCELL): don't change cell type to `allocated'.
242 (SCM_NEWCELL2): ditto.
244 * gc.c (scm_mark_locations): mark freecells too, and don't worry
245 about any possible false positives.
246 (scm_debug_newcell): don't change cell type to `allocated'.
247 (scm_debug_newcell2): ditto.
248 (scm_gc_for_newcell): ditto.
249 (scm_gc_mark): remove the tc16_allocated case.
251 2000-08-26 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
253 * gdbint.c (gdb_print): Removed superfluous macro definition.
255 * objects.c (scm_init_objects), print.c (scm_init_print), struct.c
256 (scm_init_struct): First arg to scm_make_vtable_vtable should be a
257 string, not a symbol. (`make-vtable-vtable' needs to append this
258 string to another string and then pass it through
259 `make-struct-layout'.)
261 * stacks.c (scm_init_stacks): Pass a string, not a layout object,
262 to scm_make_vtable_vtable. (Thanks to Dale P. Smith.)
264 * struct.c (scm_make_struct_layout): Removed reference to
265 "read-only string" in comment; Check that argument is a string.
266 (scm_make_vtable_vtable): Check that argument is a string.
268 * environments.c (scm_init_environments): All internal includes in
269 libguile must use the prefix "libguile/" in path names since inly
270 the top-level source directory is on the include list. (That, in
271 turn, is because we want to distinguish between system header
272 files and hedares files internal to libguile.)
274 * strings.c (scm_make_shared_substring, scm_read_only_string_p):
276 (scm_string_length, scm_string_ref, scm_substring,
277 scm_string_append): Don't accept symbols as arguments (R5RS).
279 2000-08-25 Neil Jerram <neil@ossau.uklinux.net>
281 * ports.c (scm_set_port_column_x): Fix docstring so that it
282 mentions set-port-line! rather than set-port-column! twice.
284 * guardians.c (scm_make_guardian): Remove spurious . from doc string.
286 2000-08-25 Dirk Herrmann <D.Herrmann@tu-bs.de>

305 (scm_set_smob_apply): New function.
306 (scm_smob_apply_0, scm_smob_apply_1, scm_smob_apply_2,
307 scm_smob_apply_3): New functions.
308 * eval.c (SCM_CEVAL, SCM_APPLY): Added dispatch for applicable smobs.
309 * procs.c (scm_procedure_p): Check applicable smobs.
311 2000-08-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
313 * Makefile.am (BUILT_SOURCES): Experimentally added scmconfig.h
314 also here. (This is supposed to make sure that scmconfig.h is
315 built before all sources in order to prevent that everything has
316 to be rebuilt again. Hope it works---I'm just guessing. :)
318 * fluids.c (scm_fluid_set_x): Return SCM_UNSPECIFIED.
320 2000-08-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
322 * gc.c (scm_gc_mark): Don't use GUILE_DEBUG flag to compile in
323 extra tests. (GUILE_DEBUG is only supposed to make extra
324 debugging functions available.)
326 2000-08-21 Michael Livshin <mlivshin@bigfoot.com>
328 * gc.h (SCM_GC_CARD_N_CELLS): change to be a nice non-confusing
331 2000-08-19 Michael Livshin <mlivshin@bigfoot.com>
333 * gc.c (scm_gc_sweep): added a `continue' statement that have
334 fallen through the cracks in the merge. thanks to Shuji Narazaki!
336 * gc.h: removed some stuff that broke compilation for people and
337 wasn't actually needed anyway.
339 2000-08-18 Neil Jerram <neil@ossau.uklinux.net>
341 * filesys.c (scm_fcntl): Docstring fix - missing newlines inserted.
343 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_sethost,

347 * feature.c (scm_program_arguments): New docstring.
349 * simpos.c (scm_getenv): Reflow docstring.
351 * eq.c (scm_eq_p, scm_eqv_p, scm_equal_p): Add texinfo markup to
354 * chars.c (scm_char*): Docstring fixes - texinfo markup.
356 2000-08-18 Neil Jerram <neil@ossau.uklinux.net>
358 * boolean.c (scm_not, scm_boolean_p): Docstring fixes - add
359 texinfo markup and remove trailing newlines.
361 2000-08-17 Michael Livshin <mlivshin@bigfoot.com>
363 this changes the Guile GC to use cards (aka "chunklets").
364 (most of the ideas and some of the code are by Greg Harvey, though
365 the code is probably unrecognizable now. the original chunklet
366 proposal, way back, is by Dale Jordan).
368 * tags.h: (SCM_GCTYPE16, SCM_GCCDR, SCM_GC[8]MARKP,
369 SCM_SETGC[8]MARK, SCM_CLRGC[8]MARK): moved from here into gc.h.
370 some (most) of these are probably going to be deprecated.
372 * gc.h (SCM_MARKEDP): simplified, there are no different mark bit
374 (SCM_GC_CARD_*, SCM_C_BVEC_*): lots of new macros to deal with
375 cards and bvecs (bit-vectors).
377 * gc.c: (scm_default_init_heap_size_*): defined to take cards into
378 account, but keeping more or less the same values as previously.
379 added some simple helper macros.
380 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK): defined to take cards
382 (BVEC_*, scm_mark_space_t, current_mark_space, mark_space_ptr,
383 current_mark_space_offset, mark_space_head, get_bvec,
384 clear_mark_space): new functions and supporting variables, types
385 and macros that implement mark space management.
386 (scm_igc): clear the mark space (all of it) before beginning the
388 (scm_gc_mark): changed the tests for rogue cells, much simplified
389 throughout (no different mark bit locations to worry about now).

392 (scm_gc_sweep): simplified.
393 (init_heap_seg): changed to take cards into account.
395 2000-08-16 Michael Livshin <mlivshin@bigfoot.com>
397 * stime.c (scm_c_get_internal_run_time): new function, same as
398 scm_get_internal_run_time but returns a long. it's used by the GC
399 for timekeeping, since with scm_get_internal_run_time there is a
400 (extremely theoretical) possibility of consing.
401 (scm_get_internal_run_time): redefined in terms of
402 scm_c_get_internal_run_time.
404 * stime.h: added prototype for scm_c_get_internal_run_time.
406 * gc.c (scm_gc_stats): add more obscure stats, such as: mark time,
407 sweep time, total marked cells, total swept cells, and number of
408 times GC was invoked.
409 (gc_start_stats): renamed from scm_gc_start, made static, taught
410 to init the new stats.
411 (gc_end_stats): renamed from scm_gc_end, made static, taught to
412 calculate the new stats.
413 (scm_igc): don't call gc_start_stats unless we are sure that we
414 are indeed going to collect. also, added some timekeeping between
415 the mark and sweep phases.
416 (scm_gc_sweep): count number of cells we sweep as we go.
418 * gc.h: removed prototypes for scm_gc_{start,end}.
420 2000-08-13 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
422 * alist.c (scm_assq, scm_assv, scm_assoc): Report argument type

447 2000-08-11 Neil Jerram <neil@ossau.uklinux.net>
449 * macros.c: Remove surplus newlines from end of docstrings.
451 * list.c (scm_list_tail): Add @deffnx line to docstring for
454 * keywords.c: Docstring improvements in conjunction with new
455 reference manual doc on keywords.

458 docstring. (@code(~S) should be @code{~S}.)
460 * dynl.c: Remove surplus newlines from end of docstrings.
462 2000-08-11 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
464 * eval.c (scm_eval): Backward incompatible change: Now takes an
465 environment specifier as second arg. `eval' hereby becomes R5RS
467 (scm_i_eval_x, scm_i_eval): New functions (replace

511 2000-08-09 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
513 The following changes are intended to ensure that struct instances
514 are freed before their vtables. It's optimized for the most
515 common case, which is freeing of struct instances.

553 * net_db.c: declare h_errno only if HAVE_H_ERRNO is not defined
554 (thanks to Richard Kim for the bug report).

558 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
559 scm_assoc_remove_x): Use scm_delq1_x instead of scm_delq_x, since
560 using the latter is pointless.
562 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
564 * gc.c (scm_gc_sweep): Renamed local variable from 'free' to
565 'free_struct_data' to avoid confusion with stdlib's 'free'.
567 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
569 * vectors.c (scm_make_vector): Fix the initialization order of
570 the vector such that the type cell is initialized last.
572 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
574 * struct.[ch] (scm_struct_init): Made static. Fixed not to rely
575 on the struct cell to be fully initialized.

578 initialization order of the struct such that the type cell is
581 2000-07-25 Marius Vollmer <mvo@zagadka.ping.de>
583 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
584 scm_assoc_remove_x): Remove only the first cell with a matching
587 2000-07-24 Marius Vollmer <mvo@zagadka.ping.de>
589 * stime.c (scm_strftime): Recognize a return value of zero from
590 strftime as buffer overflow and take care to detect a valid zero
591 length result regardless. Thanks to David Barts!
593 2000-07-23 Marius Vollmer <mvo@zagadka.ping.de>
595 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
596 scm_assoc_remove_x): Remove all cells whose key is eq, eqv, or
597 equal (respectively) to the argument key, not all cells that are
598 eq, eqv, or equal to the first cell with the argument key. Thanks
601 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
603 * gc.h (SCM_FREE_CELL_CDR, SCM_SET_FREE_CELL_CDR), hooks.c
604 (make_hook), modules.c (OBARRAY, USES, BINDER): Pack and unpack
605 SCM values appropriately.
607 * modules.c (scm_standard_eval_closure): Don't pass an inum to
608 scm_makcclo, but rather a long value.
610 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
612 read.c (scm_lreadrecparen), srcprop.c (scm_set_source_property_x):
613 SCM_SETCDR and SCM_WHASHSET macros don't deliver a return value.
614 Thanks to Han-Wen Nienhuys for the bug report.
616 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
618 * root.[ch] (scm_call_catching_errors): Deprecated.
620 * root.c (scm_init_root): Initialize the root smob type using the
621 standard initialization functions.
623 2000-07-17 Marius Vollmer <mvo@zagadka.ping.de>
625 * eval.c (unmemocopy): Don't rely on V being a list of at least
626 one element. Thanks to Bill Schottstaedt!
628 2000-07-15 Michael Livshin <mlivshin@bigfoot.com>
630 * gc.c (scm_done_free): new.
631 expanded comments about scm_done_malloc.
633 * gc.h: added prototype for scm_done_free
635 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
637 * gc.h (scm_take_stdin): Removed.
639 * gc.h (SCM_VALIDATE_CELL): Delegate cell checks to function
640 scm_assert_cell_valid to allow extensions to the checking
641 functionality without need to recompile everything.
643 * gc.[ch] (scm_assert_cell_valid, scm_set_debug_cell_accesses_x):
644 Added as conditionally compiled functions for the case that
645 SCM_DEBUG_CELL_ACCESSES is enabled.
647 * gc.c (debug_cells_p): Added to indicate whether compile-time
648 included cell access debugging is run-time enabled.
650 * gc.[ch] (scm_gc_running_p): Added to indicate that scm_igc is
651 being executed. Intended to be used instead of scm_gc_heap_lock
654 * error.c (scm_error), gdbint.c (SCM_GC_P): Use scm_gc_running_p
655 instead of scm_gc_heap_lock.
657 * gc.c (scm_igc): Set scm_gc_running_p to true while running.
659 * gc.c (scm_mark_locations): Don't mark free cells.
661 * weaks.c (scm_scan_weak_vectors): Use SCM_FREE_CELL_P instead of
664 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
666 * gc.c (scm_mark_locations): Minimized some variable scopes and
667 simplified the code a bit.
669 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
671 * gc.h (SCM_SET_FREE_CELL_TYPE, SCM_SET_FREE_CELL_CDR,
672 SCM_FREE_CELL_P, SCM_FREE_CELL_CDR): Added since free cells
673 should not be accessed via SCM_C[AD]R. Further, using dedicated
674 macros to access free cells allows all other cell accessing macros
675 to treat acesses to free cells as errors, thus enabling better
676 error checks for cell accesses. SCM_FREE_CELL_P is supposed to
677 replace SCM_FREEP some time.
679 * gc.h (SCM_NEWCELL, SCM_NEWCELL2), gc.c (map_free_list,
680 free_list_length, scm_check_freelist, scm_debug_newcell,
681 scm_debug_newcell2, freelist_length, scm_gc_for_newcell,
682 scm_gc_mark, scm_gc_sweep, init_heap_seg): Only use the dedicated
683 cell accessors when accessing free cells.
685 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
687 * gc.h (SCM_CELL_WORD, SCM_CELL_OBJECT): Treat the referenced
688 object as const in order to make the compiler warn about code like
689 SCM_CELL_WORD (x, n) = y. Instead, SCM_SET_CELL_WORD (x, n, y)
692 (SCM_CELL_WORD_LOC, SCM_CARLOC, SCM_CDRLOC): Return the address
693 as an address to a non-const object, since these macros are used
694 to allow direct write access to objects.
696 2000-07-07 Dirk Herrmann <D.Herrmann@tu-bs.de>
698 * hashtab.c (scm_hash_fn_create_handle_x): Signal an error if the
699 given hash table has no slots.
701 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
703 * gc.c (policy_on_error): Added in order to allow alloc_some_heap
704 to react to malloc failures in a context dependent way.
706 (scm_check_freelist): No need to flush streams before abort().
708 (scm_gc_for_newcell): Try to allocate new memory in three phases:
709 grow heap if preferred, if still no memory available collect
710 garbage, if still no memory available grow heap.
712 (heap_segment_table_size): Added to always reflect the actual
713 size of the heap segment table, because scm_n_heap_segs may differ
714 from the heap segment table size.
716 (alloc_some_heap): In case of malloc failure, react according to
717 the new policy_on_error parameter (either return to caller or
718 abort immediately). Further, keep heap_segment_table_size up to
721 (scm_init_storage): Initialize heap_segment_table_size.
723 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
725 * gh.h: Don't include <stdio.h>. Thanks to Han-Wen Nienhuys for
728 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
730 * __scm.h (SCM_OUTOFRANGE, SCM_NALLOC, SCM_HUP_SIGNAL,
731 SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL,
732 SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL, SCM_SIG_ORD,
733 SCM_ORD_SIG, SCM_NUM_SIGS): Re-introduce these as deprecated
736 * error.c (scm_wta): Re-introduce dispatching for SCM_OUTOFRANGE
737 and SCM_NALLOC, but as a deprecated feature.
739 2000-06-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
741 * debug.c: Added #include fluids.h.
743 * numbers.c (scm_gr_p, scm_leq_p, scm_geq_p): Turned into
744 primitive generics. (Thanks to Nicolas Neuss.)
746 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
748 * gc.c (alloc_some_heap): Use scm_memory_error to indicate a
749 failed attempt to get additional memory from the system.
751 (scm_gc_for_newcell): Changed the control structure to make the
752 behaviour explicit for the case that gc is not able to free any
755 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
757 * __scm.h (SCM_OUTOFRANGE): Removed.
759 * error.c (scm_wta): Removed sick dispatch code for range
760 errors. (More sick dispatches still to be removed.)
762 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
763 scm_hash_fn_remove_x): Eliminate redundant test for if unsigned
764 value is non-negative. Use scm_out_of_range to signal range
767 * hooks.c (make_hook), unif.c (scm_aind): Use scm_out_of_range to
770 * list.c (scm_list_ref, scm_list_set_x, scm_list_cdr_set_x): Fix
771 error reporting (now uses original input parameter to report wrong
772 type argument errors). Use SCM_OUT_OF_RANGE to report range
773 errors and SCM_WRONG_TYPE_ARG to report type errors.
775 * strings.c (scm_substring): Make range checks for negative
776 values explicit (former behaviour relied on an implicit
777 conversion from signed to unsigned). Don't use SCM_ASSERT for
780 * unif.c (scm_aind, scm_transpose_array, scm_bit_set_star_x,
781 scm_bit_count_star): Use scm_out_of_range to signal range
784 * unif.c (scm_transpose_array, scm_bit_position), vectors.c
785 (scm_vector_ref, scm_vector_set_x, scm_vector_move_left_x,
786 scm_vector_move_right_x): Use SCM_ASSERT_RANGE to check ranges.
788 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
790 * validate.h (SCM_VALIDATE_INUM_MIN_COPY,
791 SCM_VALIDATE_INUM_MIN_DEF_COPY, SCM_VALIDATE_INUM_RANGE_COPY):
792 Perform all range checks based on the input value. The former way
793 of using the value that is assigned to the target variable fails
794 if the assignment to the target variable itself can change the
795 value because of type conversion.
797 (SCM_ASSERT_RANGE): Use scm_out_of_range to signal range errors.
799 2000-06-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
801 * gc.c (scm_gc_for_newcell): Behave gracefully also if scm_igc
802 doesn't yield any new cells. In theory this could happen if all
803 cells allocated with NEWCELL are either in use or conservatively
804 marked and all cluster spine cells are conservatively marked.
807 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
809 * __scm.h (SCM_NALLOC): Removed.
811 * error.c (scm_wta): Removed sick dispatch code for memory
812 errors. (More sick dispatches still to be removed.)
814 * numbers.c (scm_mkbig, scm_adjbig), ports.c (scm_make_port_type),
815 random.c (scm_i_copy_rstate, scm_c_make_rstate), smob.c
816 (scm_make_smob_type), srcprop.c (scm_make_srcprops), vectors.c
817 (scm_vector_set_length_x): Now using scm_memory_error to signal
820 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
822 * __scm.h: Removed some commented code and fixed some comments.
824 (SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL,
825 SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL,
826 SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS): Removed.
828 * async.c: Removed some commented code.
830 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
832 * gc.c (scm_gc_mark, scm_gc_sweep, scm_must_malloc,
833 scm_must_realloc, scm_must_free, alloc_some_heap): Use the
834 appropriate error signalling function.
836 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
838 * root.h (scm_first_type): Removed.
840 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
842 * gc.c (MIN_GC_YIELD): Removed.
844 2000-06-28 Michael Livshin <mlivshin@bigfoot.com>
846 * gc.c (scm_gc_for_newcell): don't try to do GC if it's blocked,
849 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
851 * async.c (scm_gc_async, scm_gc_vcell, scm_sys_gc_async_thunk):
854 (scm_init_async): Moved initialization for scm_gc_async and
855 scm_gc_vcell to gc.c. Moved initialization of scm_asyncs here
858 * async.h (scm_gc_async): Not globally visible any more.
860 * gc.c (scm_gc_stats): Made callable even from within regions
863 (scm_gc_end): Eliminate the hardcoding of the marking of the
864 scm_gc_async from the gc core.
866 (scm_init_storage): Don't initialize the scm_asyncs list here.
867 This is now done in asyncs.c.
869 (scm_gc_vcell): Moved here from async.c.
871 (gc_async): Renamed from scm_gc_async, moved here from async.c
874 (gc_async_thunk): Renamed from scm_sys_gc_async_thunk and moved
877 (mark_gc_async): New hook function for scm_after_gc_c_hook.
879 (scm_init_gc): Added initialization of scm_gc_vcell and
880 gc_async. Further, add mark_gc_async to scm_after_gc_c_hook.
882 * init.c (scm_boot_guile_1): scm_init_gc requires asyncs to be
885 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
887 * gc.c (scm_igc): Removed commented code that once was intended
888 to unprotect struct types with no instances.
890 * root.h (scm_type_obj_list): Removed.
892 2000-06-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
894 * async.c (scm_init_async): Switch to standard way of smob
897 2000-06-21 Michael Livshin <mlivshin@bigfoot.com>
899 * guile-doc-snarf.in: use cut instead of sed, that's much much
900 faster. also, don't call basename more than needed. and, to gain
901 a couple of microseconds more, don't call cat needlessly. (thanks
904 2000-06-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
906 * guile-snarf.awk.in, guile-snarf.in, snarf.h: Rename SCM__I to
907 SCM_SNARF_INIT_START, SCM__D to SCM_SNARF_DOC_START, SCM__S to
908 SCM_SNARF_DOCSTRING_START and SCM__E to SCM_SNARF_DOCSTRING_END.
910 2000-06-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
912 * eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
913 #include "libguile/fluids.h".
915 * eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
916 SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
918 * root.h (scm_top_level_lookup_closure_var,
919 scm_system_transformer): Removed. (It's no sense in having the
920 *variable* be a "fluid".)
922 * root.c (mark_root): Removed marking of
923 s->top_level_lookup_closure_var and s->system_transformer.
925 * modules.c (scm_selected_module): the_module is now a fluid.
927 2000-06-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
929 * gc.h, tags.h: Be kind to compilers which must see hash signs in
930 column 0. (Thanks to Ian Grant.)
932 * numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
933 the long_long type. (Thanks to Bernard Urban.)
935 2000-06-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
937 * gc.c, gc.h (scm_default_init_heap_size_1,
938 scm_default_min_yield_1, scm_default_init_heap_size_2,
939 scm_default_min_yield_2, scm_default_max_segment_size): New global
940 variables. Can be customized by the application before booting
941 Guile. (We might want to be able to control these parameters
942 dynamically through the "options interface" in the future, but
943 note that that is additional functionality. Here we're giving
944 default values which the environment variables can override.)
946 * list.c (scm_cons_star): Updated comment.
948 * smob.h: Changed comments for scm_make_smob_type and
949 scm_make_smob_type_mfpe, warning that the latter might be
950 deprecated in a future release.
952 2000-06-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
954 * list.[ch] (scm_cons_star/cons*): Renamed from
957 * list.[ch] (scm_list_star/list*): Provided as a deprecated alias
958 for scm_cons_star/cons*.
960 * gc.c (scm_protect_object): Updated comment.
962 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX): Removed.
964 * tags.h (SCM_UNPACK_CAR, SCM_NDOUBLE_CELLP): Removed.
966 2000-06-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
968 * init.c, init.h (scm_initialized_p): Renamed from `initialized'
971 * gdbint.c (gdb_print): Print warning instead of calling scm_write
972 if Guile isn't yet initialized.
974 * print.c (scm_current_pstate, scm_make_print_state): Simplified
975 tests, using the assumption that Guile has been initialized.
977 Sun Jun 18 14:45:21 2000 Greg J. Badros <gjb@cs.washington.edu>
979 * print.c (s_scm_current_pstate): Do not segfault when the
980 print_state_pool is unitialized in `current-pstate', and better
981 verify its state before altering it in scm_make_print_state().
983 2000-06-18 Michael Livshin <mlivshin@bigfoot.com>
985 * scmsigs.c (s_scm_sigaction): guard the SIGIOT case with an
986 #ifdef -- it's missing on at least one platform. (thanks to
989 2000-06-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
991 * list.c (list*): Added documentation from common-list.scm.
993 2000-06-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
995 * gc.c (scm_unprotect_object): The reference count is guaranteed
996 to be a positive number.
998 2000-06-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1000 * eval.c: Updated comment above scm_map.
1002 2000-06-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1004 * gc.c (scm_protect_object): Avoid looking up the object handle
1006 (scm_unprotect_object): Abort if scm_unprotect_object is called on
1007 an unprotected object.
1009 2000-06-14 Michael Livshin <mlivshin@bigfoot.com>
1011 * gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
1014 2000-06-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1016 * socket.c (scm_getsockopt): Changed type for `optlen' from int to
1018 (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
1019 Ditto for `tmp_size'.
1020 (scm_addr_buffer_size): Changed type from int to size_t.
1022 * random.c: #include <string.h>. (Needed by memcpy.)
1024 * guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
1025 indicating stdin, instead of "" and don't reset ARGC. This is a
1026 workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
1027 it is correct, and perhaps even better.
1029 2000-06-14 Gary Houston <ghouston@arglist.com>
1031 * scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not
1032 defined, add SA_RESTART to the sigaction flags correctly
1033 (thanks to Dale P. Smith).
1035 2000-06-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1037 * strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
1039 * net_db.c (scm_resolv_error): Only use macro NETDB_INTERNAL if
1040 defined. It isn't on sgi irix 5.3. (Thanks to Bill Schottstaedt.)
1042 * Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
1044 2000-06-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1046 * fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
1047 since read and write buffers are allocated by `malloc'.
1049 * Makefile.am: Removed old test code.
1051 * gh_test_c.c, gh_test_repl.c: Removed.
1053 2000-06-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1055 * iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2

1060 * ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
1063 * symbols.c (scm_intern_obarray_soft,
1064 scm_sysintern0_no_module_lookup): Cast `name' to unsigned char ptr
1065 in calls to scm_strhash.
1067 * strports.c (st_resize_port): Substituted SCM_UCHARS for
1069 (st_write): Cast argument to strncpy to char ptr.
1070 (scm_mkstrport): Substituted SCM_ROUCHARS for SCM_ROCHARS.
1071 (scm_strport_to_string): Cast argument to scm_makfromstr to char
1074 * ports.c (scm_ungetc): Cast value to unsigned char ptr before
1075 storing in putback_buf.
1076 (scm_unread_string): Substituted SCM_ROCHARS for SCM_ROUCHARS.
1078 * ioext.c (s_scm_read_line): Cast result of call to
1079 scm_do_read_line to unsigned char ptr.
1081 * gdbint.c (SEND_STRING): Cast argument to char pointer.
1083 * fports.c (fport_flush): Declare `ptr' as unsigned char (was
1086 * Makefile.am (DOT_DOC_FILES): List doc-files explicitly. (We
1087 shouldn't use Make rules which aren't supported by most Make
1089 (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h". (We don't
1090 want these dependencies recorded, since they would get bogus
1091 relative paths; libguile.h is only used in gh.h and guile.c.)
1092 (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
1093 (guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
1094 (modinclude_HEADERS): Removed kw.h.
1096 * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
1097 (The preprocessor might insert spaces before the identifier.)
1099 * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
1100 Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
1102 * smob.h (scm_smobfuns): Removed deprecated type.
1104 * smob.c, smob.h (scm_newsmob): Removed deprecated function.
1105 (Replaced by `scm_make_smob_type'.)
1107 * keywords.c (scm_tc16_kw): Removed deprecated type.
1108 (Replaced by scm_tc16_keyword.)
1110 * kw.h: Removed deprecated header file.
1112 * evalext.c (serial-map): Removed deprected alias for scm_map.
1113 (Has been replaced by `map-in-order'.)
1115 * ramap.c (serial-array-copy!, serial-array-map!): Removed
1116 depracted aliases. (Replaced by `array-copy-in-order!' and
1117 `array-map-in-order'.)
1119 2000-06-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1121 * gc.h (SCM_VALIDATE_CELL): Rewritten.
1122 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
1123 SCM_SET_CELL_OBJECT): Use new version of SCM_VALIDATE_CELL.
1124 (Thanks to Han-Wen Nienhuys.)
1126 2000-06-10 Michael Livshin <mlivshin@bigfoot.com>
1128 * guile-doc-snarf.in: don't pipe the CPP output right into sed --
1129 write it to the temp file first and check the CPP return code.
1130 (I introduced this bug earlier, and this probably caused people
1131 with non-GNU C preprocessors to get empty *.x files and not to
1132 have the build fail right away...).
1134 * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
1135 -- at least my libc5-based Linux system doesn't define SIGSYS.
1137 2000-06-08 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1139 * snarf.h, guile-snarf.awk.in, guile-snarf.in: Replaced snarf
1140 markers with identifiers (SCM__I, SCM__D, SCM__S, SCM__E).
1141 (Thanks to Bernard Urban.)
1143 2000-06-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1145 * modules.c (scm_system_module_env_p): Fixed detection of system
1148 2000-06-06 Marius Vollmer <mvo@zagadka.ping.de>
1150 * scmsigs.c (scm_sigaction): Silently ignore setting handlers for
1151 `program error signals' because they can't currently be handled by
1154 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1156 * procs.h (SCM_SET_SUBRF): Added.
1158 * procs.c (scm_make_subr_opt): Don't assign to SCM_SUBRF, use
1159 SCM_SET_SUBRF instead. Thanks to Bernard Urban for the bug
1162 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1164 * gc.h (SCM_CARLOC, SCM_CDRLOC): Don't take the address of a SCM
1167 * sort.c (scm_sorted_p, scm_merge, scm_merge_list_x,
1168 scm_merge_list_step): Don't take the address of SCM_CAR. Use
1169 SCM_CARLOC instead. Thanks to Bernard Urban for the bug report.
1171 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1173 * boolean.h (SCM_TRUE_P): Removed, as people might use it as a
1174 replacement for !SCM_FALSEP.
1176 * backtrace.c (display_error_body), boolean.h (SCM_BOOLP), gc.c
1177 (scm_unhash_name), gh_data.c (gh_module_lookup), load.c
1178 (scm_primitive_load), print.c (scm_simple_format), procs.c
1179 (scm_procedure_documentation), procs.h (SCM_TOP_LEVEL), ramap.c
1180 (scm_array_fill_int), scmsigs.c (scm_sigaction), stacks.c
1181 (narrow_stack, scm_make_stack, scm_stack_id), symbols.c
1182 (scm_string_to_obarray_symbol), throw.c (scm_catch,
1183 scm_lazy_catch, scm_ithrow), unif.c (scm_make_uve, scm_array_p,
1184 scm_array_set_x, scm_bit_set_star_x, scm_bit_count_star),
1185 validate.h (SCM_VALIDATE_BOOL_COPY, SCM_VALIDATE_PROC): Replace
1186 uses of SCM_TRUE_P (x) with SCM_EQ_P (x, SCM_BOOL_T).
1188 2000-06-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1190 * eval.c (scm_badformalsp): New static function.
1191 (SCM_CEVAL): Check arguments for procedure-with-setter closures.
1192 (Thanks to Keisuke Nishida.)
1194 The major reason for Guile's slow loading speed has been the fact
1195 that a chain of Scheme level procedures has been evaluated for
1196 every top-level symbol lookup during the first pass through the
1199 The following is a kludge which I suggested four years ago, and
1200 which I've repeatedly suggested since. Personally, I've never
1201 been bothered by Guile's slow loading speed, so I thought I would
1202 let someone else do it...
1204 But since the new environments will be included first in
1205 Guile-1.5, I thought it would make people happy to get the kludge
1208 * modules.c: Added #include "libguile/vectors.h";
1209 Added #include "libguile/hashtab.h";
1210 Added #include "libguile/struct.h";
1211 Added #include "libguile/variable.h";
1212 Capture Scheme level `module-make-local-var!' to be used in the
1213 standard eval closure.
1214 (scm_standard_eval_closure): New primitive.
1216 * modules.h (scm_standard_eval_closure): Declare.
1218 * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
1219 instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
1221 * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
1222 standard eval closures.
1224 * variable.c: Code layout fixes.
1226 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1228 * Makefile.am: Added LIBS line to libpath which accidentally
1229 disappeared in the change of 2000-06-01.
1230 (Thanks to Dale P. Smith.)
1232 2000-06-03 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1234 * scmsigs.c (scm_segfault): Removed. (Was probably added by
1235 mistake since it is not mentioned in ChangeLog.)
1237 * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
1238 avoid compiler warnings in gcc. (Does this work for other
1241 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1243 * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
1245 (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
1246 SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1. It's not correct to take
1247 the address of these expressions since they use SCM_VALIDATE_CELL.
1248 (Thanks to Bernard Urban.)
1250 * dynl.c: Changed #include <ltdl.h> --> #include
1251 "libltdl/ltdl.h". (Thanks to Bill Schottstaedt.)
1253 2000-06-01 Craig Brozefsky <craig@red-bean.com>
1255 * Makefile.am: libguile_la_LDFLAGS gets -version-info args
1256 from GUILE-VERSION definition of LIBGUILE version. Added to
1257 libpath.h definitions for guileversion and libguileversion which
1258 both get their values from GUILE-VERSION definition.
1260 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1262 * numbers.h (SCM_BIGP): Don't use SCM_SMOB_PREDICATE in header
1263 file: Code using numbers should not be required to include
1266 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
1268 * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
1269 mit-pthreads.c, mit-pthreads.h: Deleted.
1271 * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]: Drop
1272 references to deleted files and fsu/mit thread support in
1275 2000-05-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
1277 * hooks.c (symbol_name, scm_create_hook): Restored the original
1278 behaviour of scm_create_hook. Changing it was bad as Carl
1279 R. Witty has pointed out.
1281 * gc.c (scm_init_gc): We can still rely on scm_create_hook to
1284 2000-05-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
1286 * gc.c (scm_init_gc): Protect scm_after_gc_hook, since this will
1287 soon not be done by scm_create_hook any longer.
1289 * hooks.c (make_hook, print_hook, scm_create_hook,
1290 scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
1291 SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
1292 scm_make_hook_with_name), init.c (scm_boot_guile_1): Hooks no
1293 longer have names. As an intermediate solution, the name
1294 predicate is emulated via object properties, but use of this
1295 feature is deprecated.
1297 * hooks.h (scm_free_hook): Removed, as it is never defined.
1299 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1301 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
1302 Un-deprecated since otherwise user code can't determine whether a
1303 number fits into an inum any longer. The names should be changed
1306 * numbers.c (scm_big2inum): Eliminated use of SCM_UNEGFIXABLE.
1308 * tags.h (SCM_UNPACK_CAR): Deprecated.
1310 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1312 * filesys.h (SCM_OPDIRP), fluids.h (SCM_FLUIDP, SCM_FLUID_NUM),
1313 fports.h (SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP), hooks.h
1314 (SCM_HOOK_ARITY), keywords.h (SCM_KEYWORDP, SCM_KEYWORDSYM),
1315 numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
1316 Replace SCM_UNPACK_CAR appropriately. Don't access cells via
1317 SCM_{SET}?C[AD]R unless they are known to be cons cells.
1319 * gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
1320 init_heap_seg): Remove unused struct member variable 'valid'.
1322 2000-05-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
1324 * fports.c (fport_write), ports.c (scm_markstream, scm_port_mode,
1325 scm_print_port_mode), ports.h (SCM_OPPORTP, SCM_OPINPORTP,
1326 SCM_OPOUTPORTP, SCM_INPUT_PORT_P, SCM_OUTPUT_PORT_P, SCM_OPENP),
1327 procs.h (SCM_CLOSCAR), unif.h (SCM_ARRAY_NDIM, SCM_ARRAY_CONTP),
1328 variable.h (SCM_VARIABLEP): Replace SCM_UNPACK_CAR
1331 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1333 * gc.c (free_list_length), hash.c (scm_hasher), macros.c
1334 (scm_macro_type), objects.c (scm_class_of), options.c
1335 (scm_options), print.c (scm_iprin1), strports.c (st_seek), throw.c
1336 (SCM_LAZY_CATCH_P): Replace SCM_UNPACK_CAR appropriately.
1338 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1340 * eval.c (scm_macroexp, SCM_CEVAL, scm_force), tags.h: Replace
1341 SCM_UNPACK_CAR with SCM_CELL_TYPE or SCM_CELL_WORD_0.
1343 * eval.c (scm_force): Add documentation.
1345 * eval.c (scm_force, scm_cons_source): Don't access cells via
1346 SCM_{SET}?C[AD]R unless they are known to be cons cells.
1348 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1350 * strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
1351 (SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP): Deprecated.
1353 * gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT): Removed #ifdef
1354 nosve #endif conditionally compiled code.
1356 2000-05-23 Michael Livshin <mlivshin@bigfoot.com>
1358 * gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
1360 2000-05-22 Michael Livshin <mlivshin@bigfoot.com>
1362 * guile-doc-snarf.in: put the preprocessed file through sed to
1363 trim all lines to 1024 chars. I hope it doesn't break anybody's
1364 sed. we'll see. (note: this is lossy trimming, i.e. the spill
1365 isn't wrapped around but actually chopped off. this seemed to me
1366 safe because the current snarfer doesn't understand multi-line
1367 cookies anyway. in the long term, it would be nice not to depend
1368 on AWK for anything.)
1370 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
1371 the previous change to this macros, after deciding to torture the
1374 2000-05-21 Michael Livshin <mlivshin@bigfoot.com>
1376 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
1377 the yucky, ugly and nasty conditional compilation back. sorry,
1378 but it was either that or requiring GAWK to build Guile.
1379 (lots of places): removed the code that implemented the old GC
1382 * init.c (scm_boot_guile_1): removed the code conditioned on
1383 !GUILE_NEW_GC_SCHEME.
1385 * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
1387 * gc.c (scm_protect_object, scm_unprotect_object): change the
1388 implementation to more efficient (at least in the time complexity
1389 sense). the calls should now also be thread-safe -- I suspect
1390 that people expect them to be. (thanks to Han-Wen Nienhuys)
1391 (lots of places): removed the code that implemented the old GC
1394 * hashtab.c (scm_hash_fn_create_handle_x): add missing
1395 SCM_REALLOW_INTS before return. I really wonder about the
1396 possible interactions between hashtables, threads & GC. it
1397 doesn't look healthy at all.
1399 2000-05-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1401 * unif.c (scm_bit_count): Fixed the parameter checks. Thanks to
1404 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1406 * __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_): Added as a new
1407 debug option to verify all accesses to cells actually access
1408 objects on the heap.
1410 * gc.h (SCM_VALIDATE_CELL): Added. Only performs validation if
1411 SCM_DEBUG_CELL_ACCESSES is set to 1.
1413 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
1414 SCM_SET_CELL_OBJECT): Use SCM_VALIDATE_CELL to check every cell
1417 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1419 * gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs,
1420 gh_scm2floats, gh_scm2doubles): Change !SCM_NIMP to SCM_IMP.
1422 * gc.c (scm_cellp): Fixed and simplified.
1424 * throw.c (JBJMPBUF, SETJBJMPBUF, SCM_JBDFRAME, SCM_SETJBDFRAME,
1425 make_jmpbuf, scm_init_throw): Now using double cells to represent
1426 jump buffers when using debug extensions.
1430 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1432 * gh.h gh_data.c gh_funcs.c (gh_new_procedure*, gh_chars2byvect,
1433 gh_shorts2svect, gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect,
1434 gh_doubles2dvect, gh_doubles2scm, gh_define, gh_lookup,
1435 gh_module_lookup): Accept const pointers as parameters.
1437 * gh.h gh_data.c (gh_int2scmb): Deprecated.
1439 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1441 * __scm.h (SCM_DEBUG_REST_ARGUMENT): Renamed from
1442 SCM_DEBUG_REST_ARGUMENTS in order to clarify that we don't test
1443 the actual arguments in the list, but rather the rest argument as
1444 a list of arguments.
1446 * validate.h (SCM_VALIDATE_REST_ARGUMENT): Added.
1448 * async.c (scm_noop), eval.c (scm_map, scm_for_each), list.c
1449 (scm_list_star, scm_append, scm_append_x), ports.c
1450 (scm_close_all_ports_except), ramap.c (scm_array_map_x,
1451 scm_array_for_each), regex-posix.c (scm_make_regexp), stacks.c
1452 (scm_make_stack), strings.c (scm_string_append), struct.c
1453 (scm_make_struct, scm_make_vtable_vtable): Validate rest arguments.
1455 * dynl.c (DYNL_GLOBAL, sysdep_dynl_link, kw_global, sym_global,
1456 scm_dynamic_link, scm_init_dynamic_linking), dynl.h
1457 (scm_dynamic_link): Removed possibility to pass flags to
1458 scm_dynamic_link, as it had no effect anyway.
1460 * filesys.c (scm_fcntl): Made single optional rest argument into
1461 a standard optional argument.
1463 * hooks.c (scm_run_hook): A list of rest arguments is never
1466 * list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
1467 strings.c (scm_string_append): Don't perform half-hearted checks
1468 to see whether the rest argument forms a proper list any more, use
1469 SCM_VALIDATE_REST_ARGUMENTS instead.
1471 * ports.c (scm_close_all_ports_except): Accept empty list of rest
1474 * posix.c (scm_convert_exec_args), print.c (scm_simple_format):
1475 Simplify verification of rest argument.
1477 * stacks.c (scm_make_stack), stacks.h (scm_make_stack), throw.c
1478 (ss_handler, handler_message): Make first mandatory rest argument
1479 of scm_make_stack into a standard mandatory argument.
1481 * unif.c (scm_transpose_array, scm_enclose_array,
1482 scm_array_in_bounds_p), unif.h (scm_transpose_array,
1483 scm_enclose_array, scm_array_in_bounds_p): Make first mandatory
1484 rest argument into a standard mandatory argument.
1486 2000-05-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
1488 * __scm.h: Added SCM_DEBUG as default debug option. (Thanks to
1489 Keisuke Nishida for the suggestion.) Added debug option
1490 SCM_DEBUG_REST_ARGUMENTS.
1492 * eval.c (scm_map, scm_for_each): Make sure all lists have the
1493 same length. Also, removed redundant parameter checks.
1495 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1497 * Makefile.am: Let 'make clean' remove *.x and *.doc files.
1499 * __scm.h: Improved explanation of giving options to make.
1501 * __scm.h (SCM_DEBUG_TYPING_STRICTNESS), tags.h
1502 (SCM_STRICT_TYPING, SCM_DEBUG_TYPING_STRICTNESS): Renamed
1503 SCM_STRICT_TYPING to SCM_DEBUG_TYPING_STRICTNESS and moved the
1504 corresponding declaration and comment to __scm.h.
1506 * _scm.h (errno), gc.h (SCM_CELLPTR, SCM_PTR_LT), numbers.c
1507 (scm_remainder, scm_modulo), numbers.h (SCM_SRS, SCM_MAKINUM,
1508 SCM_INUM): Removed conditionally compiled code for Turbo C.
1510 * gdbint.c (gdb_maybe_valid_type_p): Eliminated call to scm_tag.
1511 That check can be assumed to be redundant except for very rare
1512 conditions that actually indicate broken heap data.
1514 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1516 * numbers.c (scm_logcount, scm_integer_length): Reordered
1519 2000-05-15 Gary Houston <ghouston@arglist.com>
1521 * stime.c (scm_strftime): don't reset TZ if zone is an empty
1522 string. append a "0" to the zone for TZ.
1524 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
1526 * numbers.c (scm_logbit_p, scm_bit_extract): Reordered dispatch
1529 (scm_bit_extract): Fixed handling of bignums.
1531 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
1533 * async.c (scm_sys_gc_async_thunk), chars.h (SCM_ICHRP, SCM_ICHR,

1539 'serial-array-map!), smob.c (scm_newsmob), smob.h (scm_smobfuns,
1540 scm_newsmob), tag.c (scm_tag), tag.h (scm_tag), tags.h
1541 (scm_tc16_flo, scm_tc_flo, scm_tc_dblr, scm_tc_dblc): Wrapped
1542 deprecated code between #if (SCM_DEBUG_DEPRECATED == 0) #endif.
1544 * fports.c (scm_fport_buffer_add), ports.c (scm_input_port_p,
1545 scm_output_port_p), print.c (scm_get_print_state), validate.h
1546 (SCM_VALIDATE_CHAR): Replace use of deprecated macros
1547 SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
1548 SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
1550 2000-05-14 Gary Houston <ghouston@arglist.com>
1552 * stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
1553 TZ environment variable so that the %Z format returns the zone
1554 from the input vector instead of the system default.
1556 from Keisuke Nishida:
1557 * fports.c (scm_setvbuf): minor docstring fix.
1558 * ports.h (scm_generic_fgets): obsolete prototype deleted.
1560 2000-05-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
1562 * __scm.h: Added new section for debugging options.
1564 (SCM_DEBUG_DEPRECATED): If 1, no deprecated code is included to
1565 help developers to get rid of references to deprecated code.
1567 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,
1568 SCM_FIXABLE, SCM_FLOBUFLEN): These macros are no longer provided
1569 as part of the interface and are marked as deprecated in the
1572 * numbers.c (scm_make_real, scm_make_complex): Inlined the
1573 corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
1576 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,
1577 SCM_REAL, SCM_IMAG, SCM_REALPART, scm_makdbl, SCM_SINGP,
1578 SCM_NO_BIGDIG, SCM_NUM2DBL, scm_dblproc): Deprecated.
1580 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1582 * gc.h (scm_cell, SCM_CELL_WORD, SCM_CELL_OBJECT,
1583 SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT): Scheme cells now consist
1584 of two scm_bits_t values instead of two SCM values, because it is
1585 legal for cell entries to hold values that are not scheme objects.
1587 (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
1588 Use SCM_SETC[AD]R to modify contents of pairs.
1590 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1592 * numbers.c (IS_INF, isfinite): Added FIXME comment.
1594 (scm_abs, scm_magnitude): Make these two independent of each
1595 other. scm_abs now reports an error if given a complex argument.
1597 (scm_istr2flo, scm_integer_p). Use SCM_REAL_VALUE instead of
1598 SCM_REALPART if the object is known to be real.
1600 (scm_init_numbers): No need to use SCM_NEWREAL macro for speed
1603 * numbers.h (SCM_SINGP): Set to 0 instead of SCM_BOOL_F.
1605 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1607 * eq.c (scm_eqv_p): Separate handling of real and complex
1608 values. Remove #ifdef SCM_BIGDIG #endif test.
1610 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_scm2floats,
1611 gh_scm2doubles), hash.c (scm_hasher), ramap.c (scm_array_fill_int,
1612 ramap_rp, scm_array_map_x), random.c (vector_scale,
1613 vector_sum_squares), unif.c (scm_make_uve, scm_array_p,
1614 scm_array_set_x): Use SCM_REAL_VALUE instead of SCM_REALPART if
1615 the object is known to be real. Use SCM_COMPLEXP instead of
1616 deprecated SCM_CPLXP. Use SCM_INEXACTP instead of deprecated
1619 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1621 * numbers.c: No need to include unif.h.
1623 (IS_INF): Returned to old test for now: x == x + 1 will not work
1624 for large numbers due to rounding errors.
1625 Thanks to Kalle Olavi Niemitalo.
1627 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1629 * numbers.c (scm_divbigdig): Removed outdated comment.
1631 (scm_number_to_string, scm_string_to_number, scm_number_p,
1632 scm_real_p, scm_integer_p, scm_inexact_p, scm_gr_p, scm_leq_p,
1633 scm_geq_p, scm_make_rectangular, scm_make_polar,
1634 scm_inexact_to_exact): Added comments.

1638 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1640 * numbers.c (IS_INF): The new test is x == x + 1. The old test
1641 x == x/2 did not work for zero values. Thanks to Han-Wen Nienhuys
1644 (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
1645 scm_num2long, scm_num2long_long, scm_num2ulong): Reordered
1648 2000-05-09 Marius Vollmer <mvo@zagadka.ping.de>
1650 * scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
1651 SIGILL and SIGBUS signals. These signals are not continuable and
1652 must be handled for real right away.
1654 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1656 * numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,
1657 scm_real_part, scm_imag_part, scm_magnitude,
1658 scm_inexact_to_exact): Reordered dispatch sequence.
1660 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1662 * feature.c: No need to include "libguile/smob.h"
1664 (scm_loc_features, features, scm_add_feature, scm_init_feature):
1665 Removed variable 'scm_loc_features' as a pointer to the SCM value
1666 holding the features list. Using variable 'features' instead,
1667 which holds the interned pair. Thus, SCM_SETCDR can be used
1668 instead of pointer trickery.
1670 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1672 * alist.c (scm_acons): Use SCM{_SET}?_CELL_OBJECT as long as a
1673 cell is not known to be a valid pair.
1675 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1677 * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1): Removed
1678 ASRTSYNTAX. Using SCM_ASSYNT instead.

1684 (bodycheck): Removed.
1686 * stacks.c (stack_depth, read_frame, read_frames): Removed
1687 redundant calculation of size, minimized some variable scopes.

1692 long as a cell is not known to be a valid pair.
1694 (scm_pair_p): Eliminated redundant SCM_IMP test.
1696 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>

1699 scm_deval_args): Eliminated redundant SCM_IMP tests.
1701 * hashtab.c (scm_ihashx, scm_sloppy_assx, scm_delx_x), weaks.c
1702 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
1703 scm_make_doubly_weak_hash_table): Fixed critical sections.
1704 Thanks to Keisuke Nishida.
1706 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1708 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
1709 Fixed some goto-related initialization bugs (introduced by me).
1711 2000-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
1713 * numbers.h (SCM_INUM0): Uses SCM_MAKINUM instead of SCM_PACK.
1715 * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj): Removed.
1717 (DYNL_FILENAME, DYNL_HANDLE): Use SCM_CELL... macros instead of
1720 (SET_DYNL_HANDLE): Added.
1722 (scm_dynamic_object_p): Simplified.
1724 (scm_dynamic_unlink, scm_dynamic_func): Changed comment. Deliver
1725 better error message when accessing unlinked dynamic objects.
1726 Eliminated call to get_dynl_obj.
1728 2000-05-03 Marius Vollmer <mvo@zagadka.ping.de>
1730 * scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
1731 be an array of function pointers instead of being a pointer to an
1732 array returning function. Thanks to Kalle Olavi Niemitalo!
1734 2000-05-03 Dirk Herrmann <D.Herrmann@tu-bs.de>
1736 * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
1737 (scm_divbigbig, scm_divbigint): Don't return zero any more to
1738 indicate that a division has a remainder, return SCM_UNDEFINED
1739 instead. It is improbable that anyone actually used these
1740 functions outside of numbers.c. For this reason and due to the
1741 change in behaviour the functions are static now. Thus, if
1742 surprisingly there are users of these functions they will at least
1745 * numbers.c: Removed #ifdef SCM_BIGDIG #endif in those functions,
1746 that already have a clean dispatch order. Note: SCM_BIGDIG is
1749 * numbers.c (scm_inexact_p): Simplified.
1751 * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
1752 scm_product, scm_num2dbl, scm_angle): Reordered dispatch
1753 sequence, thereby fixing some comparisons of SCM values with
1756 * numbers.c (scm_divide): Division by zero of inums leads to an
1757 error now. (Formerly, an infinite number was returned.)
1759 Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
1760 if a division has a remainder.
1762 2000-05-02 Gary Houston <ghouston@arglist.com>
1764 * Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).

1784 call to scm_makdbl with a call to scm_make_real or
1785 scm_make_complex, depending on whether the imaginary part is known

1790 * scmsigs.c: fix the definition of orig_handlers for the case
1791 that HAVE_SIGACTION is not defined (thanks to
1792 Kalle Olavi Niemitalo).
1794 * Makefile.am: remove include_HEADERS (was libguile.h)
1795 libguile.h: moved to top level directory.
1797 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1799 * numbers.c (SCM_SWAP): Moved to the top of the file to allow for
1802 * numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,

1813 occur anywhere else throughout guile.
1815 * numbers.c (scm_quotient): Fixed parameter number in error
1818 * numbers.c (scm_remainder): Reordered dispatch sequence.
1820 2000-04-25 Gary Houston <ghouston@arglist.com>

1835 * procs.c (scm_init_iprocs), procs.h (scm_subr, scm_iproc,
1836 scm_dsubr, scm_init_iprocs): Removed.
1838 * procs.h (SCM_SUBRF, SCM_DSUBRF): Access the cell words
1839 directly instead of casting a cell to a C struct.
1841 2000-04-22 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1843 Better modularization of GC extensions through new C level GC

1901 the root build directory.
1903 * numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG
1904 instead of SCM_ASSERT (0, ...). (Some compilers will complain

1925 scm_quotient): Reordered dispatch sequence to first handle
1926 immediates, second handle bignums and finally handle generic
1927 functions respectively signal wrong type arguments. Hopefully
1928 this will allow for easier separation when goops is integrated.
1930 2000-04-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1932 * gc.c (which_seg): Use SCM2PTR to convert a non immediate SCM

2167 * numbers.c (scm_quotient, scm_modulo): Reordered to handle the
2168 case of immediate numbers parameters first. Also, only use
2169 decoded numbers for numerical comparison.
2171 2000-04-10 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2173 * objects.h: Don't redeclare scm_call_generic_0 and

2209 * async.[ch]: unexpose low-level async access macros (thanks to
2212 * validate.h: move async validation macros to async.c (nobody else
2213 needs them anyway), and rename them.
2215 2000-04-04 Michael Livshin <mlivshin@bigfoot.com>
2217 * async.h: kill the scm_async_t struct. having a heap cell
2218 pretending to be a C struct is not helthy, and is not needed here
2219 anyway, as asyncs happily fit in one heap cell.
2221 * async.c: reflect the fact that asyncs are now represented by
2222 single heap cell each.
2224 2000-04-04 Gary Houston <ghouston@arglist.com>

2286 2000-04-03 Michael Livshin <mlivshin@bigfoot.com>
2288 * guardians.c (scm_guardian_zombify): mark all zombies in a
2289 separate loop after processing all the currently known live
2290 guardians, so as to not introduce order dependencies (thanks to
2291 Gary Houston). note that the order problems are still there if
2292 some guardians are themselves zombies, but that's a sick case that
2293 I'm not going to worry about.
2294 also, make another outer loop to process zombified
2295 guardians (which are uncovered while marking zombies).

2442 (mother): New function.
2443 (coop_create): New thread spawning mechanism which uses a "mother
2444 thread". The "dummy" pthreads aren't healthy enough to give birth

2570 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2572 * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR): Use
2573 SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT. This change implies that
2574 with strict type checking enabled these macros will only work if
2575 given valid SCM parameters.

2601 SCM_NEWCELL, SCM_NEWCELL2, SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR,
2602 SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR): Moved here from
2605 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2607 * tags.h (SCM_STRICT_TYPING): New macro that, if defined,
2608 activates strict compile time type checking for variables of
2610 (SCM, SCM_PACK, SCM_UNPACK): Define according to whether
2611 SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
2612 (SCM_EQ_P): Defined as a macro equivalent for eq?.
2614 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2616 * tags.h (SCM_POINTERS_MUNGED): Removed.
2618 * gc.c (scm_gc_sweep, init_heap_seg): Removed use of
2619 SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
2621 2000-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
2623 * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
2624 SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
2625 SCM_SET_CELL_TYPE): Added a set of low level macros for accessing
2627 (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
2629 * procs.h, procs.c: Instead of SCM_{SET_}?CELL_WORD[12], use the
2630 newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
2632 2000-03-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2634 * tags.h: Disabled definition of SCM_VOIDP_TEST.
2636 Defining SCM as void * introduces problems which haven't been
2637 handled yet. Developers who work with these issues can enable it
2638 in their working copies.
2640 Disabling this definition exposes a set of newly introduced and
2641 older misuses of types which causes warning messages during
2642 compilation. We'll fix this successively.
2644 * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
2645 in order to obtain a value of type SCM.
2646 (scm_cellp): Updated with new changes to scm_mark_locations.
2648 * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
2650 * continuations.c (scm_make_cont): Removed cast of size_t into
2653 * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
2655 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2657 * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for
2658 shifting, not constant. Thanks to Dale P. Smith.
2660 * numbers.c (scm_sum, scm_difference): Don't test a SCM value
2661 for being less than zero. Decode it to a C value first. Again,
2664 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2666 * numbers.h, ramap.c, struct.h, vectors.h: Don't use SCM2PTR for
2667 non scheme values. If raw data is stored in SCM variables, it has
2668 to be accessed using SCM_UNPACK until a better solution is found.
2670 2000-03-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2672 * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
2673 pointer-arithmetic induced by the SCM_PACK/UNPACK change.
2675 * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
2677 * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
2679 * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
2681 * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
2683 * async.c, __scm.h: Removed lots of the old async click logic. It
2684 is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
2685 __scm.h. Let's try this out and dump the old code after the
2686 threads reorganization.
2687 (set-tick-rate, set-switch-rate): Conditionally removed.
2689 2000-03-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2691 * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
2692 made SCM values into pointers. This turned an arithmetic
2693 computation of the address of the vcell into a pointer-arithmetic
2694 one, thereby screwing up marking of structs.
2695 Bugfix 2: Removed incompletely introduced loop variable `j' used
2696 when protecting the tail array of a struct.
2698 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2700 * struct.h (SCM_STRUCT_DATA): Don't cast SCM values to pointers.
2702 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2704 * symbols.h, symbols.c (scm_strhash): Declare the string
2705 parameter as constant, since it is not modified.
2707 * symbols.c (scm_intern_obarray_soft,
2708 scm_sysintern0_no_module_lookup): Can now pass constant strings
2709 to scm_strhash without need for casting.
2711 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2713 * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS): Don't cast SCM
2714 values to pointers. Use SCM2PTR instead.
2716 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2718 * async.c (scm_set_tick_rate, scm_set_switch_rate): Don't unpack
2719 results of SCM_INUM.
2721 2000-03-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2723 * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
2724 GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
2725 GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
2727 * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
2728 min_yield_fraction, min_yield, adjust_min_yield): Renamed from
2729 SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
2730 gc_trigger, adjust_gc_trigger.
2732 * gc.c (alloc_some_heap): Further improvement of minimal heap size
2734 (SCM_MAX): New macro.
2735 (scm_freelist_t): New field: collected_1. Previous amount of
2737 (gc_sweep_freelist_finish): Trigger based on two last values of
2738 freelist->collected to avoid unnecessary allocation due to
2740 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
2741 Adjusted to 45000 cells, 40% and 40%. Gives quick startup
2742 without extra heap allocation.
2744 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2746 * numbers.h (SCM_MAKINUM): The parameter to SCM_MAKINUM should
2747 already be a C value. No need to unpack it.
2749 * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t
2750 if we know it fits into an inum.
2752 * ramap.c (ramap_rp): An scm_tc7_[ui]vect object does point to a
2753 field of long values. In contrast, SCM_VELTS accesses a field of
2756 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2758 * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
2760 (scm_gc_yield_1): New variable: Holds previous yield. Used to
2761 make better judgements.
2762 (gc_sweep_freelist_finish): Inserted explanation of use of
2765 * print.h, stacks.h, options.c, options.h: Changed C++
2768 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2770 * tags.h (SCM2PTR, PTR2SCM): Use SCM_PACK / SCM_UNPACK correctly.
2772 * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
2773 SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS): Use SCM_PACK /
2774 SCM_UNPACK / SCM2PTR correctly.
2776 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2778 * gc.c (adjust_gc_trigger): Improved documentation.
2779 (alloc_some_heap): Since gc_trigger is used against
2780 freelist->collected, this is the value which should be used to
2781 predict minimum growth.
2783 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2785 * eval.h: Fix mixup of packed/unpacked SCM values. (Thanks
2786 Thien-Thi Nguyen for the patch.)
2788 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2790 * numbers.c (scm_ash): Fixed typing problems with the second
2791 parameter and added some documentation. (Thanks Thien-Thi Nguyen
2792 for indicating the problem.)
2794 2000-03-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2796 * gc.c, gc.h (scm_gc_yield): New variable.
2797 (adjust_gc_trigger): Use scm_gc_yield.
2798 (alloc_some_heap): Use scm_gc_yield instead of
2799 scm_gc_cells_collected.
2801 * coop-threads.c: Addd #include "root.h", #include "strings.h".
2803 * debug.c: Added #include "root.h". (Thanks to Thien-Thi Nguyen.)
2805 * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
2806 trigger adjustmeant: Take yield (freed cells) for all freelists
2808 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
2809 to 50000 cell heap with 45% trigger.
2810 (scm_gc_cells_collected): Reintroduced.
2811 (SCM_HEAP_SIZE): New macro.
2812 (scm_gc_sweep): Reintroduced correct computation of
2813 scm_cells_allocated.
2814 (scm_freelist_t): Corrected commentary for field `cluster_size':
2815 Clustersize counts objects, not cells; New member
2816 `clusters_allocated'.
2818 2000-03-19 Michael Livshin <mlivshin@bigfoot.com>
2820 * *.[hc]: add Emacs magic at the end of file, to ensure GNU
2823 2000-03-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2825 * threads.h: Added #include "libguile/throw.h". (Thanks to
2828 2000-03-18 Michael Livshin <mlivshin@bigfoot.com>
2830 * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
2831 names, anyone got any better ones?)
2833 * gc.h: (typedef struct scm_freelist_t) remove from here.
2835 * gc.c: (CELL_UP, CELL_DN) made these macros take additional
2836 parameter (the span).
2837 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
2838 (typedef struct scm_freelist_t) moved here from gc.h, it had no
2839 business being externally visible.
2840 (typedef struct scm_heap_seg_data_t) renamed from
2841 scm_heap_seg_data, to be style-compliant.
2842 (scm_mark_locations) if the possible pointer points to a
2843 double-cell, check that it's properly aligned.
2844 (init_heap_seg) align double-cells properly, work with the
2845 assumption that the segment size divides cleanly by cluster size.
2846 (round_to_cluster_size) new function.
2847 (alloc_some_heap, make_initial_segment) use round_to_cluster_size
2848 to satisfy the new init_heap_seg invariant.
2850 2000-03-18 Dirk Herrmann <D.Herrmann@tu-bs.de>

2907 2000-03-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2909 * gc.c, gc.h: Cleanup of the change of 2000-03-15.
2910 Cluster sizes are now independent of GC trigger values.
2911 GUILE_GC_TRIGGER_n can now specify a relative trigger value:
2912 A negative integer gives fraction of total heap size in percent.
2913 (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
2915 * init.c (scm_boot_guile_1): Introduced new variable
2916 GUILE_MAX_SEGMENT_SIZE; New environment variable names:
2917 GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
2918 GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
2920 2000-03-16 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2922 * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
2923 freeing of segment work with the new GC scheme. (Thanks to
2924 Michael Livshin.) Oops, also happened to make GUILE_NEW_GC_SCHEME
2925 the default, but I'll let this change stay in CVS Guile since this
2926 code is not expected to contain serious bugs.
2928 2000-03-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2930 * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
2932 (scm_free_list_length): New procedure (GUILE_DEBUG).
2933 Fixed a small but serious bug introduced by the previous change.
2935 * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
2936 loop and declare as register.
2938 * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
2941 Wed Mar 15 08:27:04 2000 Greg J. Badros <gjb@cs.washington.edu>
2943 * fluids.c: Docstring patch from Keisuke Nishida. Some
2944 reindentation, too, and a couple formals renamed. Should
2945 fluid-set! return UNSPECIFIED instead of a value?
2947 Wed Mar 15 08:24:58 2000 Greg J. Badros <gjb@cs.washington.edu>
2949 * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
2950 generate the latter from the concrete listing of the former. Then
2951 make guile-procedures.txt depend on DOT_DOC_FILES instead of
2952 *.doc, so that rebuilding it works.
2954 Wed Mar 15 08:12:14 2000 Greg J. Badros <gjb@cs.washington.edu>
2956 * libguile.h: Include libguile/validate.h. Thanks Keisuke Nishida!
2958 * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
2959 with nothing and \n, respectively. Thanks Keisuke Nishida for
2960 noticing this problem.
2962 2000-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2964 * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
2965 new way of allocating heap. It makes Guile fast, but still
2968 * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
2969 allocating heap. The basic idea is to trigger GC every Nth
2970 allocated cell and grow heap when free list runs out. The scheme
2971 has been extended so that GC isn't triggered until all remaining
2972 cells are used. The implementation is also prepared for
2973 development in the direction of POSIX threads.
2975 * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
2976 SCM_EXPHEAP should return half of the heap size.
2978 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2980 The following change to init.c is only enabled if Guile was
2981 configured with --enable-guile-debug.
2983 * init.c (scm_i_getenv_int): New function.
2984 (scm_boot_guile_1): Use the environment variables
2985 GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
2986 they exist. (This may be replaced by a Scheme level mechanism in
2989 * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
2990 scm_assoc. (Thanks to Keisuke Nishida.)
2992 2000-03-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2994 * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
2995 scm_nil, scm_t. (Thanks to Keisuke Nishida.)
2997 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2999 * init.c (scm_boot_guile_1): Use same initial segment size for
3000 1-word and 2-word segments. Having the smaller size causes Guile
3001 to GC too often. Obviously something needs to be done to allow
3002 for a smaller 2-word segment without this to happen. (The amount
3003 of heap for each type should be automatically adapted to the
3004 application somehow.)
3006 [Almost all of these changes should be documented in the NEWS
3009 * gc.h (scm_freelist_t): New type.
3011 * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
3013 * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
3014 all of Guile basics fits into one segment and there suitable room
3016 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
3018 (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
3019 Freelists now contains information about object span, cells
3020 collected and amount of cells in heap segments belonging to the
3022 (scm_heap_size, scm_gc_cells_collected): Removed.
3024 * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
3026 * Makefile.am (libguile_la_LDFLAGS): Bumped library version
3029 * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
3030 numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
3031 rewrite of handling of real and complex numbers.
3032 (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
3033 removed along with the support for floats. (Float vectors are
3036 * tags.h (scm_tcs_bignums): Removed.
3037 (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
3038 Use SCM_BIGSIGN(x) to test for sign!
3039 (scm_tc16_big): The new bignum type.
3040 (SCM_REAL_PART, SCM_IMAG_PART): Removed.
3042 * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
3043 (scm_makdbl): Deprecated.
3044 (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
3045 (SCM_SINGP): Deprecated.
3047 (SCM_INEXP, SCM_CPLXP): Deprecated.
3048 (SCM_INEXACTP, SCM_COMPLEXP): New macros.
3049 (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
3050 SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
3051 (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
3052 for doubles and complex numbers.
3053 (SCM_REAL_VALUE): New selector for doubles.
3054 (scm_double_t, scm_complex_t): New types.
3057 * numbers.c (scm_floprint, scm_floequal): Removed.
3058 (scm_print_real, scm_print_complex, scm_real_equalp,
3059 scm_complex_equalp): New functions.
3061 * unif.c (scm_makflo): Removed.
3063 * smob.h (SCM_SMOB_PREDICATE): New macro.
3064 (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
3065 SCM_RETURN_NEWSMOB3): New macros.
3067 1999-11-21 Michael Livshin <mlivshin@bigfoot.com>
3069 The following changes implement primitive support for double cells
3070 (i.e. four-word cells) and change the representation of some
3071 things to multi-cells instead of cons+malloc. (Applied and
3074 * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
3075 (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
3076 multi-cell access macros (used by the ones below).
3077 (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
3080 * gc.c (scm_freelist2): multi-cell freelists.
3081 (inner_map_free_list): map_free_list, parameterized on ncells.
3082 "nn cells in segment mm" was misleading for ncells > 1; changed to
3083 "objects". still print cells too, though.
3084 (scm_map_free_list): rewritten using inner_map_free_list.
3085 (scm_check_freelist): get freelist as parameter, since now we have
3087 (scm_debug_newcell2): multi-cell variants of
3089 (scm_gc_for_newcell): take ncells and freelist pointer as
3091 (scm_gc_mark): add case for tc7_pws (procedures with setters are
3093 (scm_gc_sweep): don't free the float data, since it's not malloced
3095 (init_heap_seg): didn't understand what n_new_objects stood for,
3096 so changed to n_new_cells.
3097 (make_initial_segment): new function, makes an initial segment
3098 according to given ncells.
3099 (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
3101 * numbers.c (scm_makdbl): no malloc'ing needed, so the
3102 {DEFER,ALLOW}_INTS thing removed.
3104 * numbers.h (struct scm_dbl): changed to represent a double cell,
3105 with the number in the second half.
3107 * dynwind.c: changed the wind-guards representation to double
3110 * procs.c, procs.h: changed the procedure-with-setter representation
3113 * async.c, async.h: made async representation a double cell.
3115 * dynl.c: made dynamic_obj representation a double cell.
3117 2000-03-13 Gary Houston <ghouston@arglist.com>
3119 * ports.c (flush_void_port): renamed to flush_port_default.
3120 (end_input_void_port): renamed to end_input_default.
3122 * init.c (scm_standard_stream_to_port): create a void port instead
3123 of opening /dev/null if the standard file descriptors are bad.
3124 advantages: no portability problems, doesn't waste a file descriptor,
3125 simplifies the code (thanks to Marius for the idea).
3127 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
3129 * void ports: make reading from a void port give EOF instead of
3131 * ports.c (s_scm_sys_make_void_port): modified docstring.
3132 (fill_input_void_port): new proc.
3133 (scm_init_ports): set up fill_input_void_port.
3134 * ports.c (scm_port_non_buffer): new proc.
3135 (scm_void_port): call scm_port_non_buffer.
3137 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
3138 which was incorrectly appended.
3140 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3142 * guile-doc-snarf.in: Don't use absolute path for `sed'. (Note
3143 that we can't use autoconf for this. Autoconf itself relies on
3144 the existence of `sed' somewhere on your path.) (Thanks to Dirk
3147 2000-03-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3149 * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
3150 EXTRA_libguile_la_SOURCES.
3152 * iselect.h: Always declare scm_internal_select.
3154 * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
3155 end. Also let scm_internal_select be a real function also when
3158 * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
3160 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3162 * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
3163 SCM_ASYNC_TICK. (This is a preparation for POSIX threads support,
3164 and kind of an experiment: Will this cause problems?)
3166 Sun Mar 12 13:26:30 2000 Greg J. Badros <gjb@cs.washington.edu>
3168 * Makefile.am: Added *.doc to DISTCLEANFILES.
3170 2000-03-12 Gary Houston <ghouston@arglist.com>
3172 * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
3173 the fdes is valid before doing anything else. check that
3174 the file descriptor supports the modes required.
3175 (scm_fport_buffer_add): don't throw an error if fstat doesn't
3176 work: just use the default buffer size.
3178 * throw.c: change an outdated comment about scm_internal_catch
3179 BODY: it doesn't take a jumpbuf arg.
3181 * init.c (scm_standard_stream_to_port): install a handler in case
3182 scm_fdes_to_port throws an error. don't check here whether the
3183 file descriptor is valid, since scm_fdes_to_port will do that.
3184 set the revealed count depending on whether the port got the
3185 standard file descriptor.
3186 (stream_body_data): new type.
3187 (stream_body, stream_handler): new procs.
3189 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3191 * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
3192 Renamed from SCMWORD.
3194 * tags.h (SCM_NCELLP): Removed (SCMWORD).
3196 * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
3198 * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
3199 feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,
3200 hash.c, keywords.h, macros.c, numbers.c, numbers.h, objects.c,
3201 objects.h, options.c, pairs.h, ports.c, ports.h, print.c,
3202 procs.h, ramap.c, read.c, smob.c, smob.h, srcprop.h, stacks.c,
3203 stacks.h, strports.c, struct.c, struct.h, tag.c, tags.h,
3204 throw.c, unif.c, unif.h, variable.h, vectors.h, weaks.c,
3205 weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
3206 SCM_ASSCM, SCM_ASWORD, SCM_CARW).
3208 * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
3210 * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
3211 tags.h: Fixed copyright notices.
3213 * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
3215 2000-03-12 Marius Vollmer <mvo@zagadka.ping.de>
3217 * init.c (scm_standard_stream_to_port): Check whether the file
3218 descriptor is valid and substitute "/dev/null" when not.
3220 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3222 * coop-defs.h (struct timespec): Conditionally defined.
3224 * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
3227 * readline.c (match_paren): Bugfix: First arg to select is not
3228 number of descriptors but the number of the highest descriptor +
3231 This is a preliminary attempt at a cleanup of the threads support
3232 code. It moves things to better places, makes arguments more
3233 consistent with the POSIX API (which is used in GNOME's glib), and
3234 adds new functionality.
3236 * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
3238 * coop-defs.h (scm_mutex_trylock): New macro: alias for
3240 (scm_cond_init): Changed definition to
3241 coop_new_condition_variable_init.
3243 * coop.c: #include <errno.h>
3244 (coop_timeout_qinsert): Moved here from iselect.c
3245 (coop_new_mutex_init, coop_new_condition_variable_init): New
3246 functions. The strange names are temporary. Use scm_mutex_init
3247 and scm_cond_init instead.
3248 (coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
3249 is ANSI C, but should we check for individual error codes in
3251 (coop_condition_variable_timed_wait_mutex): New function.
3252 (coop_key_create, coop_setspecific, coop_getspecific,
3253 coop_key_delete): New functions.
3255 * iselect.c (coop_timout_qinsert): Moved to coop.c
3257 2000-03-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3259 * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
3260 SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
3262 * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
3265 * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
3266 SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
3267 proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
3269 * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
3272 2000-03-11 Dale P. Smith <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
3274 * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
3275 scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
3276 logical functions from SCM.
3278 (logand, logior, logxor, logtest, logbit?): Extended scheme
3279 logical functions to use bignums from SCM.
3281 (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
3282 lognot from using bignums.
3284 Thu Mar 9 11:33:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3286 * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
3287 eliminating some warnings.
3289 * unif.c, strports.c, print.c, options.c: Fix some warnings on
3292 * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
3293 what the scm_return_first* functions do.
3295 2000-03-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
3297 * libguile/*.[ch]: make a distinction between SCM as a generic
3298 name for a Scheme object (now a void*), and SCM as 32 bit word for
3299 storing tags and immediates (now a long int). Introduced
3300 SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
3301 code in the process: arbiter.c (use macros), unif.c (scm_array_p),
3303 Wed Mar 8 10:15:59 2000 Greg J. Badros <gjb@cs.washington.edu>
3305 * numbers.c: Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
3306 various logXXX primitives. Thanks Eric Moore!
3308 Tue Mar 7 08:05:22 2000 Greg J. Badros <gjb@cs.washington.edu>
3310 * run-test, remaining-docs-needed: Added these scripts. The
3311 second one is only temporary until the docstring additions are
3312 complete. run-test may best live on, but is here mostly for
3313 convenience and awareness for now.
3315 * hash.c: Docs, minor cleanup patch from Dirk Herrman.
3317 Thu Mar 2 16:06:58 2000 Greg J. Badros <gjb@cs.washington.edu>
3319 * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
3320 displaying the expected type. Use SCM_LISTn in a couple places
3321 instead of scm_cons-ing by hand.
3323 * __scm.h: Added SCM_ASSERT_TYPE macro.
3325 * validate.h, scm_validate.h: Added the former, as a renamed
3326 version of the latter with SCM_ASSERT_TYPE used in
3327 SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
3329 * Makefile.am: Rename scm_validate.h to validate.h.
3331 * *.c, *.h: Include validate.h, not scm_validate.h (old name's
3332 prefix was superfluous).
3334 Thu Mar 2 15:33:12 2000 Greg J. Badros <gjb@cs.washington.edu>
3336 * hashtab.c: Improved documentation for lots of functions. Added
3337 handwritten docs for `hash-fold'.
3339 Thu Mar 2 15:13:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3341 * list.c: Added hand-written docs for `del{q,v,ete}1!'.
3343 Thu Mar 2 12:38:30 2000 Greg J. Badros <gjb@cs.washington.edu>
3345 * list.c: Moved append docs to append! Thanks Dirk Hermann. Also,
3346 added append docs from R4RS.
3348 * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
3349 Thanks Dirk Hermann!
3351 * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
3352 deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
3354 * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
3355 Drop use of SCM_P for function prototypes... assume an ANSI C
3356 compiler. Thanks Dirk Hermann!
3358 Sat Feb 19 12:20:12 2000 Greg J. Badros <gjb@cs.washington.edu>
3360 * ports.c: Made `set-port-column!' and `set-port-line!' each
3361 return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
3362 that caused a seg fault. Also fixed `set-port-column!'s
3363 docstring. Thanks Han-Wen Nienhuys for finding the bug!
3365 Sun Feb 13 19:11:42 2000 Greg J. Badros <gjb@cs.washington.edu>
3367 * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
3368 regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
3369 strings.c, variable.c: Added lots of documentation, cleaned up
3370 some existing documentation. Occasionally changed formal params
3371 to match docs. Also folded an #ifdef into the inners of a
3372 primitive instead of having two copies of the primitive
3373 (`get-internal-real-time', from stime.c)
3375 Sun Feb 13 18:12:19 2000 Greg J. Badros <gjb@cs.washington.edu>
3377 * ports.c: Added docs for primitives missing them. Written by
3380 Sun Feb 13 09:40:36 2000 Greg J. Badros <gjb@cs.washington.edu>
3382 * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
3383 just execing guile-func-name-check. Thanks Michael Livshin!
3385 Thu Feb 10 11:43:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3387 * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
3388 dead code. Patch from Michael Livshin.
3390 * guile-doc-snarf.in: Tweak to work with Sun/HP sh. Patch from
3393 2000-02-09 Gary Houston <ghouston@arglist.com>
3395 * init.c (scm_init_standard_ports): when stdout is a tty, make the
3396 current-output-port unbuffered by default. this is less confusing
3397 for interactive use. it was line-buffered because of a
3398 performance problem with unbuffered ports, but I think it will be
3401 2000-02-08 Gary Houston <ghouston@arglist.com>
3403 * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
3406 * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
3407 HAVE_TZNAME are defined, use an empty string instead of giving two
3408 spurious compile-time errors.
3410 Tue Feb 8 13:57:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3412 * ports.c: Doc patches from Richard Kim. Pasted from MIT Scheme.
3415 Mon Feb 7 09:07:31 2000 Greg J. Badros <gjb@cs.washington.edu>
3417 * macros.c: Doc patches from Richard Kim. Pasted from scm.texi.
3419 Sun Feb 6 20:26:21 2000 Greg J. Badros <gjb@cs.washington.edu>
3421 * pairs.c: Doc patches from Richard Kim. Pasted from MIT Scheme
3422 (which is GNU GPL'd).
3424 2000-01-31 Gary Houston <ghouston@arglist.com>
3426 * strings.h: don't use SCM_P. don't include <string.h>.
3427 * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
3429 * strings.c (scm_string_ref): make the 2nd argument compulsory.
3430 previously it defaulted to zero for no good reason that I can see.
3431 use a local variable for SCM_INUM (k). replace
3432 SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
3434 (scm_makfromstr): cosmetic changes.
3436 (scm_string): Accept only chars in the list, not strings, for
3437 conformance to R5RS (particularly for list->string, which is
3438 supposed to be the inverse of string->list.) remove
3439 SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
3440 scm_makstr handles the cell allocation. when reporting wrong-type
3441 arg, don't report the position as 1.
3443 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
3445 2000-01-29 Gary Houston <ghouston@arglist.com>
3447 * posix.c (scm_pipe): rewrote the docstring.
3449 * filesys.c (scm_select, retrieve_select_type, get_element,
3450 fill_select_type, set_element): modified so that Scheme
3451 "select" tests port buffers for the ability to provide input
3452 or accept output. Previously only the underlying file descriptors
3453 were checked. Rewrote the docstring.
3455 Thu Jan 27 10:14:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3457 * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
3458 from Gregg Reynolds. Thanks Gregg!
3460 Thu Jan 27 09:59:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3462 * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
3463 adding "x" prefix to the line so that guile-func-name-check
3464 doesn't complain unnecessarily.
3466 Wed Jan 26 17:33:52 2000 Greg J. Badros <gjb@cs.washington.edu>
3468 * throw.c: Factor out an #ifdef/#else/#endif choice more finely
3469 for maintainability.
3471 * strop.c: Documentation added by Gregg A. Reynolds. Pasted in
3474 Wed Jan 26 10:02:11 2000 Greg J. Badros <gjb@cs.washington.edu>
3476 * tag.c: Added doc for `tag', but mark as deprecated since Mikael
3477 suggests removing tag.c altogether (and using a new `class-of'
3480 * strings.c: Added documentation from Gregg A. Reynolds. Edited
3481 a bit by me to use FOO instead of @var{foo} and to have the
3482 summary come before preconditions on input. Also dropped trailing
3485 * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
3486 function with scm_make_subr_opt w/ last arg of 0 so it is not
3487 visible at the Scheme level. Mikael says that this is the right
3488 thing because the first arg to the proc is the guts of a compiled
3489 closure and shouldn't be exposed to the Scheme level.
3491 Tue Jan 25 17:15:47 2000 Greg J. Badros <gjb@cs.washington.edu>
3493 * sort.c: typo in comment fixed.
3495 * keywords.c: Added documentation.
3497 * guardians.c: Added documentation (could be better).
3499 * gc.c: Added docs for gc-set-debug-check-freelist.
3501 * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
3503 * boolean.c: Added docs for `not', `boolean?' (by hand).
3505 Tue Jan 25 13:28:56 2000 Greg J. Badros <gjb@cs.washington.edu>
3507 * random.c: Added documentation, from SLIB page:
3508 http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
3510 Mon Jan 24 17:50:20 2000 Greg J. Badros <gjb@cs.washington.edu>
3512 * variable.c, version.c: Added documentation, written by hand
3513 since I could not find anything already written that was
3516 2000-01-23 Gary Houston <ghouston@arglist.com>
3518 * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
3519 not defined (thanks to Richard Y. Kim).
3521 Thu Jan 20 13:00:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3523 * Makefile.in: Removed, this is auto-generated.
3525 Thu Jan 20 11:33:47 2000 Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
3527 * list.c: Put some variable initialization code at the point of
3528 declaration; Added a comment for list*; Formatting changes.
3530 * load.c: use SCM_NNULLP to make sure the end of a list is not
3533 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3535 * backtrace.c (scm_display_error_message): Bugfix: Don't use
3536 result of scm_list_p as C boolean.
3537 (scm_display_error_message, scm_set_print_params_x): Use new
3538 validation macros. (Thanks to Dirk Herrmann.)
3540 * net_db.c (scm_resolv_error): Cast result from hstrerror.
3542 * strports.c (st_end_input): Inserted parenthesis to get operator
3545 * list.h (scm_init_list): Removed SCM_P around prototypes.
3547 * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
3548 filesys.c, posix.c: Converted docstrings to ANSI C format and
3549 escaped " occurring inside string literals.
3551 Tue Jan 18 13:21:08 2000 Mikael Djurfeldt <mdj@r11n07-s.pdc.kth.se>
3553 * posix.c (scm_mknod): Escape " occuring inside docstring.
3555 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3557 * alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,
3558 evalext.c, filesys.c, gc.c, hash.c, hashtab.c, ioext.c,

3563 symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
3564 weaks.c: Converted docstrings to ANSI C format.
3566 * filesys.c (scm_chmod), simpos.c (scm_system), version
3567 (scm_version), vports (scm_make_soft_port): Escape " occuring
3570 Mon Jan 17 11:41:22 2000 Greg J. Badros <gjb@cs.washington.edu>
3572 * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
3573 SCM_VALIDATE_LONG_COPY
3575 * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
3576 SCM_VALIDATE_INUM_COPY to let bigger numbers be used. Rename a
3577 couple of formal arguments (and fix their uses) to make arguments
3578 match the documentation.
3580 2000-01-14 <mstachow@alum.mit.edu>
3582 * Makefile.am: Augment path when running guile-doc-snarf so
3583 guile-func-name-check is found.
3585 Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
3587 * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
3588 def, not SCM_MAKINUM(def); thanks Janis Bzerins!
3590 Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3592 * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
3593 the way guile-1.3.4 worked, but #if 0 out the version using
3594 SCM_VALIDATE_INUM_COPY for stricter testing.
3596 Tue Jan 11 18:24:18 2000 Greg J. Badros <gjb@cs.washington.edu>
3598 * guile-doc-snarf.in: Use new $fullfilename for running
3599 guile-func-name-check, and put "$fullfilename" and "$filename" in
3600 quotes at uses to make sure re-splitting on whitespace does not
3601 occur (so filenames w/ embedded whitespace would work okay, though
3602 I sure hope we never have to deal with that! :-) ). Thanks to
3603 Mikael for pointing out the source_dir != build_dir was broken.
3605 Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
3607 * scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
3608 SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
3609 SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
3610 macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
3613 * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
3614 then return whether it's an open port (was validating that it was
3615 an open port -- this was a bug I introduced back in December, but
3616 my careful reading of diffs caught it).
3618 * numbers.c: Recombine the two conditional-compilation paths for
3619 all the log* primitives -- they were split based on #ifndef
3620 scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
3621 some bugs and inconsistencies in the two sets of implementations.
3622 (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
3624 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
3625 SCM_VALIDATE_INUM_COPY once where it should've been used.
3627 * fluids.c (scm_internal_with_fluids): Use
3628 SCM_VALIDATE_LIST_COPYLEN.
3630 * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
3631 this is questionable as it relaxes type safety, but other changes
3632 were useful and all SCM_NUM2LONG's should probably be
3633 revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
3635 * evalext.c: line-break change on 1 line.
3637 * eval.c (nconc2last): Takes a non-empty list as its first
3638 argument, not just a list.
3640 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
3642 Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3644 * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
3645 net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
3648 * symbols.c (scm_sysintern0): Fixed the function name in a
3649 scm_misc_error invocation.
3651 * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
3652 use scm_return_first to ward off latent GC bug that Mikael caught.
3654 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
3655 used before but should've been.
3657 2000-01-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3659 * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
3660 SCM_FUNC_CAST_ARBITRARY_ARGS.
3662 Tue Jan 11 13:44:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3664 * guile-func-name-check.in: Added this script to statically check
3665 #define FUNC_NAME, #undef FUNC_NAME in the source.
3667 * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
3668 redundant comment, semicolon; caught by new guile-func-name-check
3671 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
3672 Caught by new guile-func-name-check-script.
3674 * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
3676 * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
3677 guile-func-name-check.
3679 * guile-doc-snarf.in: Run guile-func-name-check on the file before
3682 Tue Jan 11 11:31:10 2000 Greg J. Badros <gjb@cs.washington.edu>
3684 * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
3685 port function take const void*, not void*.
3687 Tue Jan 11 11:18:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3689 * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
3690 strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
3691 SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
3692 consistency with the other macros dealing with immediate
3693 characters. (Similar to INT -> INUM change a week or so ago).
3695 Tue Jan 11 10:41:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3697 * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
3698 net_db.c, read.c, socket.c: Update error messages to use ~A for
3699 %s, ~S for %S to work with new `simple-format' format and be
3700 standardized better.
3702 * print.h, print.c (scm_simple_format): Added `simple-format'
3703 primitive. It's the old scm_display_error, with ARGS now a rest
3704 parameter, and the destination first instead of last (and a couple
3705 new capabilities inspired by `format' -- #t as destination means
3706 current-output-port, #f means return the formatted text as a
3709 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
3711 * backtrace.c (scm_display_error_message): Rewrote to use
3712 scm_simple_format() procedure.
3714 * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
3716 2000-01-09 Marius Vollmer <mvo@zagadka.ping.de>
3718 Finally applied the libltdl patch from Thomas Tanner, with slight
3721 * DYNAMIC-LINKING: Removed because it is obsolete.
3722 * dynl.c: Use ANSI prototypes.
3723 (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
3724 * scmconfig.h.in: Do not change, as it is automatically generated.
3726 1999-07-25 Thomas Tanner <tanner@ffii.org>
3728 * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
3730 * Makefile.am: likewise, add INCLTDL (libltdl headers) to
3731 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
3733 * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
3734 * guile.c: register preloaded modules
3735 * scmconfig.h.in: remove obsolete symbols
3737 2000-01-09 Gary Houston <ghouston@arglist.com>
3739 * These changes should make it unnecessary to call tzset from
3740 Scheme after modifying the TZ environment variable, even if the
3741 system date facilities cache the value.
3742 * stime.c (setzone, scm_localtime): added comments.
3743 (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
3744 (setzone): don't call tzset.
3745 (restorezone): call tzset only if HAVE_TZSET is defined.
3746 (scm_tzset): don't define if HAVE_TZSET not defined. Change the
3747 doc string to indicate that this procedure isn't likely to do
3749 (scm_localtime, scm_strftime, scm_mktime): call tzset if
3750 LOCALTIME_CACHE is defined.
3752 2000-01-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3754 * posix.c (scm_sync): Return SCM_UNSPECIFIED.
3756 2000-01-09 Gary Houston <ghouston@arglist.com>
3758 * eval.c: define scm_unbound_variable_key ('unbound-variable).
3759 scm_lookupcar1: throw an error with key 'unbound-variable instead
3760 of 'misc-error when an unbound variable is encountered.
3762 * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
3763 scm_symlink, scm_readlink, scm_lstat),
3764 posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
3765 scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
3767 simpos.c (scm_system),
3768 stime.c (scm_times, scm_strptime):
3769 move the HAVE_XXX feature tests out of the procedure bodies.
3770 don't use SCM_SYSMISSING.
3771 scm_validate.h (SCM_SYSMISSING): removed.
3772 error.h, error.c (scm_sysmissing): comment that this is deprecated.
3773 see ChangeLog entry for 1999-12-28.
3775 Sat Jan 8 19:52:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3777 * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
3779 Sat Jan 8 17:06:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3781 * backtrace.c: Fix spelling typo in a comment.
3783 * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
3784 text. Reformatted some of the expansions.
3786 Fri Jan 7 15:50:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3788 * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
3789 report the position of the argument.
3791 * error.h, error.c (scm_out_of_range_pos): Added this function to
3792 take extra "pos" argument, the position number of the errant
3795 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
3797 * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
3798 and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
3799 prefers that and I'm reasonably indifferent.
3801 Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
3803 * snarf.h: Factor out differences between C++ and non-C++ into
3804 SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
3805 definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
3806 Mikael's macros, below, but changed names and SCM_SNARFING no
3807 longer expands to include %%% -- that must appear in the argument
3808 so that the token appears at the call-site as a reminder).
3810 2000-01-07 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3812 * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
3813 snarf macro definitions.
3815 2000-01-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3817 * chars.c (scm_integer_to_char): Use Greg's nice
3818 SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
3821 Thu Jan 6 11:48:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3823 * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
3825 Thu Jan 6 11:22:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3827 * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
3828 instead of GUILE_PROC.
3830 Thu Jan 6 11:21:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3832 * alist.c: Do not report mismatch errors on some uses of `tmp' (do
3833 this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
3836 Thu Jan 6 09:54:33 2000 Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
3838 * scm_validate.h: Remove some redundant NIMP tests.
3840 * alist.c: minimize scope of the tmp variables, and initialize
3841 them when declared. The strange SCM_NIMP tests are replaced by
3842 SCM_CONSP tests that more closely reflect the intended semantics.
3843 However, we don't get a performance penalty here, because the
3844 SCM_CONSP test was performed by the ALISTCELL test anyway. * The
3845 extremely ugly use of ASRTGO macros was removed: The calls to
3846 ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
3847 label parameter that only exists when SCM_RECKLESS is not defined.
3848 This works, because ASRTGO itself is defined in a way that it only
3849 makes use of the label parameter if SCM_RECKLESS is not defined
3850 (shudder!). Does guile make at all use of the possibility to
3851 define SCM_RECKLESS? * Codesize is likely to be reduced, since
3852 instead of two calls to SCM_ASSERT performed by the ALISTCELL test
3853 we now only get one test.
3855 * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
3856 SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
3857 some variables in `list?'. Fix `reverse' and `reverse!'
3858 primitives to handle improper lists better.
3860 Wed Jan 5 11:24:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3862 * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
3863 macros and SCM_DEFINE macros to match GNU coding standards.
3865 Wed Jan 5 11:04:24 2000 Greg J. Badros <gjb@cs.washington.edu>
3867 * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
3869 Wed Jan 5 10:59:06 2000 Greg J. Badros <gjb@cs.washington.edu>
3871 * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
3872 better consistency with the names of other SCM_VALIDATE_ macros
3873 and better conformance to guile naming policy.
3875 Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
3877 * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
3878 SCM_VALIDATE instead of 1 to avoid a check on the argument (since
3879 it's not the actual name of the formal).
3881 * guile-snarf.awk.in: Do argument/number mismatch checking and
3882 print warnings in an Emacs compile-mode parseable format.
3884 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
3885 SCM_OUTOFRANGE as 3rd argument.
3887 * random.c: Fix argument/number mismatch (that I introduced :-( ).
3889 * __scm.h: Do not #define SCM_ARG* when snarfing;
3890 lets us distinguish between 1 and SCM_ARG1 when snarfing as only
3891 the former (using the number) requires the argument to match the
3892 formal in the current argument snarfing check.
3894 * snarf.h: Give new definition of SCM_ASSERT when in
3895 snarfing mode to output a lexically-identifiable sequence that the
3896 guile-snarf.awk script uses to verify argument/position matching.
3898 * ramap.c: Remove extraneous #undef FUNC_NAME.
3900 Wed Jan 5 08:36:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3902 * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
3903 current version of the same functionality; it writes the .x output
3904 to stdout instead of directly into the file.
3906 Wed Jan 5 08:15:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3908 * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
3909 posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
3910 redundant with the safer macros. Patch from Dirk Hermann applied
3911 by hand. Thanks Dirk!
3913 * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
3916 * ramap.c: whitespace change.
3918 Tue Jan 4 14:21:35 2000 Greg J. Badros <gjb@cs.washington.edu>
3920 * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
3921 removals from Dirk Hermann.
3923 * alist.c: Rename formals to match the parameter names in the
3924 documentation, updates to documentation. Thanks Dirk Hermann!
3926 2000-01-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3928 * eval.c (SCM_CEVAL): Reverse order of
3929 scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
3930 (Thanks to Brad Knotwell.)
3932 Mon Jan 3 08:30:02 2000 Greg Harvey <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
3934 * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
3937 * pairs.h: Added a comment about the need for the SCM_SETCAR in
3940 Mon Jan 3 08:25:19 2000 Greg J. Badros <gjb@cs.washington.edu>
3942 * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
3943 SCM_NIMP tests that were redundant are now eliminated. Patches
3944 from Dirk Hermann applied by hand.
