6 2000-08-19 Michael Livshin <mlivshin@bigfoot.com>
8 * gc.c (scm_gc_sweep): added a `continue' statement that have
9 fallen through the cracks in the merge. thanks to Shuji Narazaki!
11 * gc.h: removed some stuff that broke compilation for people and
12 wasn't actually needed anyway.
14 2000-08-18 Neil Jerram <neil@ossau.uklinux.net>
16 * filesys.c (scm_fcntl): Docstring fix - missing newlines inserted.

34 texinfo markup and remove trailing newlines.
36 2000-08-17 Michael Livshin <mlivshin@bigfoot.com>
38 this changes the Guile GC to use cards (aka "chunklets").
39 (most of the ideas and some of the code are by Greg Harvey, though
40 the code is probably unrecognizable now. the original chunklet
41 proposal, way back, is by Dale Jordan).
43 * tags.h: (SCM_GCTYPE16, SCM_GCCDR, SCM_GC[8]MARKP,
44 SCM_SETGC[8]MARK, SCM_CLRGC[8]MARK): moved from here into gc.h.
45 some (most) of these are probably going to be deprecated.
47 * gc.h (SCM_MARKEDP): simplified, there are no different mark bit
49 (SCM_GC_CARD_*, SCM_C_BVEC_*): lots of new macros to deal with
50 cards and bvecs (bit-vectors).
52 * gc.c: (scm_default_init_heap_size_*): defined to take cards into
53 account, but keeping more or less the same values as previously.
54 added some simple helper macros.
55 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK): defined to take cards
57 (BVEC_*, scm_mark_space_t, current_mark_space, mark_space_ptr,
58 current_mark_space_offset, mark_space_head, get_bvec,
59 clear_mark_space): new functions and supporting variables, types
60 and macros that implement mark space management.
61 (scm_igc): clear the mark space (all of it) before beginning the
63 (scm_gc_mark): changed the tests for rogue cells, much simplified
64 throughout (no different mark bit locations to worry about now).
65 (scm_mark_locations): don't consider card header cells.
67 (scm_gc_sweep): simplified.
68 (init_heap_seg): changed to take cards into account.
70 2000-08-16 Michael Livshin <mlivshin@bigfoot.com>
72 * stime.c (scm_c_get_internal_run_time): new function, same as
73 scm_get_internal_run_time but returns a long. it's used by the GC
74 for timekeeping, since with scm_get_internal_run_time there is a
75 (extremely theoretical) possibility of consing.
76 (scm_get_internal_run_time): redefined in terms of
77 scm_c_get_internal_run_time.
79 * stime.h: added prototype for scm_c_get_internal_run_time.
81 * gc.c (scm_gc_stats): add more obscure stats, such as: mark time,
82 sweep time, total marked cells, total swept cells, and number of
84 (gc_start_stats): renamed from scm_gc_start, made static, taught
85 to init the new stats.
86 (gc_end_stats): renamed from scm_gc_end, made static, taught to
87 calculate the new stats.
88 (scm_igc): don't call gc_start_stats unless we are sure that we
89 are indeed going to collect. also, added some timekeeping between
90 the mark and sweep phases.
91 (scm_gc_sweep): count number of cells we sweep as we go.
93 * gc.h: removed prototypes for scm_gc_{start,end}.
95 2000-08-13 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
97 * alist.c (scm_assq, scm_assv, scm_assoc): Report argument type
98 error for the alist rather than the sublist where the type
99 mismatch is discovered.

130 reference manual doc on keywords.
132 * error.c (scm_error_scm): Fix texinfo syntax error in
133 docstring. (@code(~S) should be @code{~S}.)
135 * dynl.c: Remove surplus newlines from end of docstrings.
137 2000-08-11 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
139 * eval.c (scm_eval): Backward incompatible change: Now takes an
140 environment specifier as second arg. `eval' hereby becomes R5RS
142 (scm_i_eval_x, scm_i_eval): New functions (replace
144 (scm_eval2, scm_eval_3): Deprecated.
145 (scm_top_level_lookup_closure_var): Deprecated.

168 scm_interaction_environment ().
170 * script.c (scm_shell): Pass scm_the_root_module () as second arg
173 * load.c (load): Use `scm_selected_module' to compute second arg
174 to new scm_i_eval_x; Don't call it if module system hasn't booted.
175 (scm_read_and_eval_x): Deprecated.
176 #include "modules.h".
178 * debug.c (scm_local_eval): Use scm_i_eval and scm_i_eval_x.
179 (scm_start_stack): Use scm_i_eval.
181 * strports.c: #include "modules.h".
183 * print.c (scm_simple_format): Be case-insensitive for ~A and ~S
186 2000-08-09 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
188 The following changes are intended to ensure that struct instances
189 are freed before their vtables. It's optimized for the most
190 common case, which is freeing of struct instances.
192 * gc.c (scm_gc_mark, scm_gc_sweep): Remove vcell = 1 magic.
193 (scm_structs_to_free): New variable.
194 (scm_gc_sweep): Hook up structs to free on the scm_structs_to_free
197 * struct.h (SCM_STRUCT_GC_CHAIN, SCM_SET_STRUCT_GC_CHAIN): New
199 (scm_structs_to_free, scm_struct_prehistory): Declare.
201 * struct.c (scm_make_struct, scm_make_vtable_vtable): Structs
202 handles are now double cells; Initialize SCM_STRUCT_GC_CHAIN to
204 (scm_struct_gc_init, scm_free_structs): New GC C hooks.
205 (scm_struct_prehistory): Install them.
207 * init.c (scm_boot_guile_1): Call scm_struct_prehistory.
209 2000-08-06 Marius Vollmer <mvo@zagadka.ping.de>
211 * read.c (scm_flush_ws): Include filename in error message when it
214 2000-08-05 Marius Vollmer <mvo@zagadka.ping.de>
216 * iselect.c: Include <unistd.h>. Thanks to Bertrand Petit!
218 2000-08-02 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
220 * struct.c (scm_make_struct_layout, scm_make_struct,
221 scm_make_vtable_vtable): Updated documentation.
223 * print.c (scm_simple_format): Bugfix: Coerce port before using
226 2000-07-31 Gary Houston <ghouston@arglist.com>
228 * net_db.c: declare h_errno only if HAVE_H_ERRNO is not defined
229 (thanks to Richard Kim for the bug report).
231 2000-07-30 Marius Vollmer <mvo@zagadka.ping.de>
233 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
234 scm_assoc_remove_x): Use scm_delq1_x instead of scm_delq_x, since
235 using the latter is pointless.
237 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
239 * gc.c (scm_gc_sweep): Renamed local variable from 'free' to
240 'free_struct_data' to avoid confusion with stdlib's 'free'.
242 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
244 * vectors.c (scm_make_vector): Fix the initialization order of
245 the vector such that the type cell is initialized last.
247 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
249 * struct.[ch] (scm_struct_init): Made static. Fixed not to rely
250 on the struct cell to be fully initialized.
252 * struct.c (scm_make_struct, scm_make_vtable_vtable): Fix the
253 initialization order of the struct such that the type cell is
256 2000-07-25 Marius Vollmer <mvo@zagadka.ping.de>
258 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
259 scm_assoc_remove_x): Remove only the first cell with a matching
262 2000-07-24 Marius Vollmer <mvo@zagadka.ping.de>
264 * stime.c (scm_strftime): Recognize a return value of zero from
265 strftime as buffer overflow and take care to detect a valid zero
266 length result regardless. Thanks to David Barts!
268 2000-07-23 Marius Vollmer <mvo@zagadka.ping.de>
270 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
271 scm_assoc_remove_x): Remove all cells whose key is eq, eqv, or
272 equal (respectively) to the argument key, not all cells that are
273 eq, eqv, or equal to the first cell with the argument key. Thanks
276 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
278 * gc.h (SCM_FREE_CELL_CDR, SCM_SET_FREE_CELL_CDR), hooks.c
279 (make_hook), modules.c (OBARRAY, USES, BINDER): Pack and unpack
280 SCM values appropriately.
282 * modules.c (scm_standard_eval_closure): Don't pass an inum to
283 scm_makcclo, but rather a long value.
285 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
287 read.c (scm_lreadrecparen), srcprop.c (scm_set_source_property_x):
288 SCM_SETCDR and SCM_WHASHSET macros don't deliver a return value.
289 Thanks to Han-Wen Nienhuys for the bug report.
291 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
293 * root.[ch] (scm_call_catching_errors): Deprecated.
295 * root.c (scm_init_root): Initialize the root smob type using the
296 standard initialization functions.
298 2000-07-17 Marius Vollmer <mvo@zagadka.ping.de>
300 * eval.c (unmemocopy): Don't rely on V being a list of at least
301 one element. Thanks to Bill Schottstaedt!
303 2000-07-15 Michael Livshin <mlivshin@bigfoot.com>
305 * gc.c (scm_done_free): new.
306 expanded comments about scm_done_malloc.
308 * gc.h: added prototype for scm_done_free
310 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
312 * gc.h (scm_take_stdin): Removed.
314 * gc.h (SCM_VALIDATE_CELL): Delegate cell checks to function
315 scm_assert_cell_valid to allow extensions to the checking
316 functionality without need to recompile everything.
318 * gc.[ch] (scm_assert_cell_valid, scm_set_debug_cell_accesses_x):
319 Added as conditionally compiled functions for the case that
320 SCM_DEBUG_CELL_ACCESSES is enabled.
322 * gc.c (debug_cells_p): Added to indicate whether compile-time
323 included cell access debugging is run-time enabled.
325 * gc.[ch] (scm_gc_running_p): Added to indicate that scm_igc is
326 being executed. Intended to be used instead of scm_gc_heap_lock
329 * error.c (scm_error), gdbint.c (SCM_GC_P): Use scm_gc_running_p
330 instead of scm_gc_heap_lock.
332 * gc.c (scm_igc): Set scm_gc_running_p to true while running.
334 * gc.c (scm_mark_locations): Don't mark free cells.
336 * weaks.c (scm_scan_weak_vectors): Use SCM_FREE_CELL_P instead of
339 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
341 * gc.c (scm_mark_locations): Minimized some variable scopes and
342 simplified the code a bit.
344 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
346 * gc.h (SCM_SET_FREE_CELL_TYPE, SCM_SET_FREE_CELL_CDR,
347 SCM_FREE_CELL_P, SCM_FREE_CELL_CDR): Added since free cells
348 should not be accessed via SCM_C[AD]R. Further, using dedicated
349 macros to access free cells allows all other cell accessing macros
350 to treat acesses to free cells as errors, thus enabling better
351 error checks for cell accesses. SCM_FREE_CELL_P is supposed to
352 replace SCM_FREEP some time.
354 * gc.h (SCM_NEWCELL, SCM_NEWCELL2), gc.c (map_free_list,
355 free_list_length, scm_check_freelist, scm_debug_newcell,
356 scm_debug_newcell2, freelist_length, scm_gc_for_newcell,
357 scm_gc_mark, scm_gc_sweep, init_heap_seg): Only use the dedicated
358 cell accessors when accessing free cells.
360 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
362 * gc.h (SCM_CELL_WORD, SCM_CELL_OBJECT): Treat the referenced
363 object as const in order to make the compiler warn about code like
364 SCM_CELL_WORD (x, n) = y. Instead, SCM_SET_CELL_WORD (x, n, y)
367 (SCM_CELL_WORD_LOC, SCM_CARLOC, SCM_CDRLOC): Return the address
368 as an address to a non-const object, since these macros are used
369 to allow direct write access to objects.
371 2000-07-07 Dirk Herrmann <D.Herrmann@tu-bs.de>
373 * hashtab.c (scm_hash_fn_create_handle_x): Signal an error if the
374 given hash table has no slots.
376 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
378 * gc.c (policy_on_error): Added in order to allow alloc_some_heap
379 to react to malloc failures in a context dependent way.
381 (scm_check_freelist): No need to flush streams before abort().
383 (scm_gc_for_newcell): Try to allocate new memory in three phases:
384 grow heap if preferred, if still no memory available collect
385 garbage, if still no memory available grow heap.
387 (heap_segment_table_size): Added to always reflect the actual
388 size of the heap segment table, because scm_n_heap_segs may differ
389 from the heap segment table size.
391 (alloc_some_heap): In case of malloc failure, react according to
392 the new policy_on_error parameter (either return to caller or
393 abort immediately). Further, keep heap_segment_table_size up to
396 (scm_init_storage): Initialize heap_segment_table_size.
398 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
400 * gh.h: Don't include <stdio.h>. Thanks to Han-Wen Nienhuys for
403 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
405 * __scm.h (SCM_OUTOFRANGE, SCM_NALLOC, SCM_HUP_SIGNAL,
406 SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL,
407 SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL, SCM_SIG_ORD,
408 SCM_ORD_SIG, SCM_NUM_SIGS): Re-introduce these as deprecated
411 * error.c (scm_wta): Re-introduce dispatching for SCM_OUTOFRANGE
412 and SCM_NALLOC, but as a deprecated feature.
414 2000-06-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
416 * debug.c: Added #include fluids.h.
418 * numbers.c (scm_gr_p, scm_leq_p, scm_geq_p): Turned into
419 primitive generics. (Thanks to Nicolas Neuss.)
421 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
423 * gc.c (alloc_some_heap): Use scm_memory_error to indicate a
424 failed attempt to get additional memory from the system.
426 (scm_gc_for_newcell): Changed the control structure to make the
427 behaviour explicit for the case that gc is not able to free any
430 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
432 * __scm.h (SCM_OUTOFRANGE): Removed.
434 * error.c (scm_wta): Removed sick dispatch code for range
435 errors. (More sick dispatches still to be removed.)
437 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
438 scm_hash_fn_remove_x): Eliminate redundant test for if unsigned
439 value is non-negative. Use scm_out_of_range to signal range
442 * hooks.c (make_hook), unif.c (scm_aind): Use scm_out_of_range to
445 * list.c (scm_list_ref, scm_list_set_x, scm_list_cdr_set_x): Fix
446 error reporting (now uses original input parameter to report wrong
447 type argument errors). Use SCM_OUT_OF_RANGE to report range
448 errors and SCM_WRONG_TYPE_ARG to report type errors.
450 * strings.c (scm_substring): Make range checks for negative
451 values explicit (former behaviour relied on an implicit
452 conversion from signed to unsigned). Don't use SCM_ASSERT for
455 * unif.c (scm_aind, scm_transpose_array, scm_bit_set_star_x,
456 scm_bit_count_star): Use scm_out_of_range to signal range
459 * unif.c (scm_transpose_array, scm_bit_position), vectors.c
460 (scm_vector_ref, scm_vector_set_x, scm_vector_move_left_x,
461 scm_vector_move_right_x): Use SCM_ASSERT_RANGE to check ranges.
463 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
465 * validate.h (SCM_VALIDATE_INUM_MIN_COPY,
466 SCM_VALIDATE_INUM_MIN_DEF_COPY, SCM_VALIDATE_INUM_RANGE_COPY):
467 Perform all range checks based on the input value. The former way
468 of using the value that is assigned to the target variable fails
469 if the assignment to the target variable itself can change the
470 value because of type conversion.
472 (SCM_ASSERT_RANGE): Use scm_out_of_range to signal range errors.
474 2000-06-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
476 * gc.c (scm_gc_for_newcell): Behave gracefully also if scm_igc
477 doesn't yield any new cells. In theory this could happen if all
478 cells allocated with NEWCELL are either in use or conservatively
479 marked and all cluster spine cells are conservatively marked.
482 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
484 * __scm.h (SCM_NALLOC): Removed.
486 * error.c (scm_wta): Removed sick dispatch code for memory
487 errors. (More sick dispatches still to be removed.)
489 * numbers.c (scm_mkbig, scm_adjbig), ports.c (scm_make_port_type),
490 random.c (scm_i_copy_rstate, scm_c_make_rstate), smob.c
491 (scm_make_smob_type), srcprop.c (scm_make_srcprops), vectors.c
492 (scm_vector_set_length_x): Now using scm_memory_error to signal
495 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
497 * __scm.h: Removed some commented code and fixed some comments.
499 (SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL,
500 SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL,
501 SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS): Removed.
503 * async.c: Removed some commented code.
505 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
507 * gc.c (scm_gc_mark, scm_gc_sweep, scm_must_malloc,
508 scm_must_realloc, scm_must_free, alloc_some_heap): Use the
509 appropriate error signalling function.
511 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
513 * root.h (scm_first_type): Removed.
515 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
517 * gc.c (MIN_GC_YIELD): Removed.
519 2000-06-28 Michael Livshin <mlivshin@bigfoot.com>
521 * gc.c (scm_gc_for_newcell): don't try to do GC if it's blocked,
524 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
526 * async.c (scm_gc_async, scm_gc_vcell, scm_sys_gc_async_thunk):
529 (scm_init_async): Moved initialization for scm_gc_async and
530 scm_gc_vcell to gc.c. Moved initialization of scm_asyncs here
533 * async.h (scm_gc_async): Not globally visible any more.
535 * gc.c (scm_gc_stats): Made callable even from within regions
538 (scm_gc_end): Eliminate the hardcoding of the marking of the
539 scm_gc_async from the gc core.
541 (scm_init_storage): Don't initialize the scm_asyncs list here.
542 This is now done in asyncs.c.
544 (scm_gc_vcell): Moved here from async.c.
546 (gc_async): Renamed from scm_gc_async, moved here from async.c
549 (gc_async_thunk): Renamed from scm_sys_gc_async_thunk and moved
552 (mark_gc_async): New hook function for scm_after_gc_c_hook.
554 (scm_init_gc): Added initialization of scm_gc_vcell and
555 gc_async. Further, add mark_gc_async to scm_after_gc_c_hook.
557 * init.c (scm_boot_guile_1): scm_init_gc requires asyncs to be
560 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
562 * gc.c (scm_igc): Removed commented code that once was intended
563 to unprotect struct types with no instances.
565 * root.h (scm_type_obj_list): Removed.
567 2000-06-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
569 * async.c (scm_init_async): Switch to standard way of smob
572 2000-06-21 Michael Livshin <mlivshin@bigfoot.com>
574 * guile-doc-snarf.in: use cut instead of sed, that's much much
575 faster. also, don't call basename more than needed. and, to gain
576 a couple of microseconds more, don't call cat needlessly. (thanks
579 2000-06-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
581 * guile-snarf.awk.in, guile-snarf.in, snarf.h: Rename SCM__I to
582 SCM_SNARF_INIT_START, SCM__D to SCM_SNARF_DOC_START, SCM__S to
583 SCM_SNARF_DOCSTRING_START and SCM__E to SCM_SNARF_DOCSTRING_END.
585 2000-06-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
587 * eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
588 #include "libguile/fluids.h".
590 * eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
591 SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
593 * root.h (scm_top_level_lookup_closure_var,
594 scm_system_transformer): Removed. (It's no sense in having the
595 *variable* be a "fluid".)
597 * root.c (mark_root): Removed marking of
598 s->top_level_lookup_closure_var and s->system_transformer.
600 * modules.c (scm_selected_module): the_module is now a fluid.
602 2000-06-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
604 * gc.h, tags.h: Be kind to compilers which must see hash signs in
605 column 0. (Thanks to Ian Grant.)
607 * numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
608 the long_long type. (Thanks to Bernard Urban.)
610 2000-06-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
612 * gc.c, gc.h (scm_default_init_heap_size_1,
613 scm_default_min_yield_1, scm_default_init_heap_size_2,
614 scm_default_min_yield_2, scm_default_max_segment_size): New global
615 variables. Can be customized by the application before booting
616 Guile. (We might want to be able to control these parameters
617 dynamically through the "options interface" in the future, but
618 note that that is additional functionality. Here we're giving
619 default values which the environment variables can override.)
621 * list.c (scm_cons_star): Updated comment.
623 * smob.h: Changed comments for scm_make_smob_type and
624 scm_make_smob_type_mfpe, warning that the latter might be
625 deprecated in a future release.
627 2000-06-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
629 * list.[ch] (scm_cons_star/cons*): Renamed from
632 * list.[ch] (scm_list_star/list*): Provided as a deprecated alias
633 for scm_cons_star/cons*.
635 * gc.c (scm_protect_object): Updated comment.
637 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX): Removed.
639 * tags.h (SCM_UNPACK_CAR, SCM_NDOUBLE_CELLP): Removed.
641 2000-06-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
643 * init.c, init.h (scm_initialized_p): Renamed from `initialized'
646 * gdbint.c (gdb_print): Print warning instead of calling scm_write
647 if Guile isn't yet initialized.
649 * print.c (scm_current_pstate, scm_make_print_state): Simplified
650 tests, using the assumption that Guile has been initialized.
652 Sun Jun 18 14:45:21 2000 Greg J. Badros <gjb@cs.washington.edu>
654 * print.c (s_scm_current_pstate): Do not segfault when the
655 print_state_pool is unitialized in `current-pstate', and better
656 verify its state before altering it in scm_make_print_state().
658 2000-06-18 Michael Livshin <mlivshin@bigfoot.com>
660 * scmsigs.c (s_scm_sigaction): guard the SIGIOT case with an
661 #ifdef -- it's missing on at least one platform. (thanks to
664 2000-06-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
666 * list.c (list*): Added documentation from common-list.scm.
668 2000-06-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
670 * gc.c (scm_unprotect_object): The reference count is guaranteed
671 to be a positive number.
673 2000-06-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
675 * eval.c: Updated comment above scm_map.
677 2000-06-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
679 * gc.c (scm_protect_object): Avoid looking up the object handle
681 (scm_unprotect_object): Abort if scm_unprotect_object is called on
682 an unprotected object.
684 2000-06-14 Michael Livshin <mlivshin@bigfoot.com>
686 * gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
689 2000-06-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
691 * socket.c (scm_getsockopt): Changed type for `optlen' from int to
693 (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
694 Ditto for `tmp_size'.
695 (scm_addr_buffer_size): Changed type from int to size_t.
697 * random.c: #include <string.h>. (Needed by memcpy.)
699 * guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
700 indicating stdin, instead of "" and don't reset ARGC. This is a
701 workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
702 it is correct, and perhaps even better.
704 2000-06-14 Gary Houston <ghouston@arglist.com>
706 * scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not
707 defined, add SA_RESTART to the sigaction flags correctly
708 (thanks to Dale P. Smith).
710 2000-06-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
712 * strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
714 * net_db.c (scm_resolv_error): Only use macro NETDB_INTERNAL if
715 defined. It isn't on sgi irix 5.3. (Thanks to Bill Schottstaedt.)
717 * Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
719 2000-06-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
721 * fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
722 since read and write buffers are allocated by `malloc'.
724 * Makefile.am: Removed old test code.
726 * gh_test_c.c, gh_test_repl.c: Removed.
728 2000-06-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
730 * iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2
733 * inet_aton.c (inet_aton): Cast init value for `cp'.
735 * ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
738 * symbols.c (scm_intern_obarray_soft,
739 scm_sysintern0_no_module_lookup): Cast `name' to unsigned char ptr
740 in calls to scm_strhash.
742 * strports.c (st_resize_port): Substituted SCM_UCHARS for
744 (st_write): Cast argument to strncpy to char ptr.
745 (scm_mkstrport): Substituted SCM_ROUCHARS for SCM_ROCHARS.
746 (scm_strport_to_string): Cast argument to scm_makfromstr to char
749 * ports.c (scm_ungetc): Cast value to unsigned char ptr before
750 storing in putback_buf.
751 (scm_unread_string): Substituted SCM_ROCHARS for SCM_ROUCHARS.
753 * ioext.c (s_scm_read_line): Cast result of call to
754 scm_do_read_line to unsigned char ptr.
756 * gdbint.c (SEND_STRING): Cast argument to char pointer.
758 * fports.c (fport_flush): Declare `ptr' as unsigned char (was
761 * Makefile.am (DOT_DOC_FILES): List doc-files explicitly. (We
762 shouldn't use Make rules which aren't supported by most Make
764 (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h". (We don't
765 want these dependencies recorded, since they would get bogus
766 relative paths; libguile.h is only used in gh.h and guile.c.)
767 (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
768 (guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
769 (modinclude_HEADERS): Removed kw.h.
771 * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
772 (The preprocessor might insert spaces before the identifier.)
774 * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
775 Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
777 * smob.h (scm_smobfuns): Removed deprecated type.
779 * smob.c, smob.h (scm_newsmob): Removed deprecated function.
780 (Replaced by `scm_make_smob_type'.)
782 * keywords.c (scm_tc16_kw): Removed deprecated type.
783 (Replaced by scm_tc16_keyword.)
785 * kw.h: Removed deprecated header file.
787 * evalext.c (serial-map): Removed deprected alias for scm_map.
788 (Has been replaced by `map-in-order'.)
790 * ramap.c (serial-array-copy!, serial-array-map!): Removed
791 depracted aliases. (Replaced by `array-copy-in-order!' and
792 `array-map-in-order'.)
794 2000-06-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
796 * gc.h (SCM_VALIDATE_CELL): Rewritten.
797 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
798 SCM_SET_CELL_OBJECT): Use new version of SCM_VALIDATE_CELL.
799 (Thanks to Han-Wen Nienhuys.)
801 2000-06-10 Michael Livshin <mlivshin@bigfoot.com>
803 * guile-doc-snarf.in: don't pipe the CPP output right into sed --
804 write it to the temp file first and check the CPP return code.
805 (I introduced this bug earlier, and this probably caused people
806 with non-GNU C preprocessors to get empty *.x files and not to
807 have the build fail right away...).
809 * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
810 -- at least my libc5-based Linux system doesn't define SIGSYS.
812 2000-06-08 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
814 * snarf.h, guile-snarf.awk.in, guile-snarf.in: Replaced snarf
815 markers with identifiers (SCM__I, SCM__D, SCM__S, SCM__E).
816 (Thanks to Bernard Urban.)
818 2000-06-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
820 * modules.c (scm_system_module_env_p): Fixed detection of system
823 2000-06-06 Marius Vollmer <mvo@zagadka.ping.de>
825 * scmsigs.c (scm_sigaction): Silently ignore setting handlers for
826 `program error signals' because they can't currently be handled by
829 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
831 * procs.h (SCM_SET_SUBRF): Added.
833 * procs.c (scm_make_subr_opt): Don't assign to SCM_SUBRF, use
834 SCM_SET_SUBRF instead. Thanks to Bernard Urban for the bug
837 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
839 * gc.h (SCM_CARLOC, SCM_CDRLOC): Don't take the address of a SCM
842 * sort.c (scm_sorted_p, scm_merge, scm_merge_list_x,
843 scm_merge_list_step): Don't take the address of SCM_CAR. Use
844 SCM_CARLOC instead. Thanks to Bernard Urban for the bug report.
846 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
848 * boolean.h (SCM_TRUE_P): Removed, as people might use it as a
849 replacement for !SCM_FALSEP.
851 * backtrace.c (display_error_body), boolean.h (SCM_BOOLP), gc.c
852 (scm_unhash_name), gh_data.c (gh_module_lookup), load.c
853 (scm_primitive_load), print.c (scm_simple_format), procs.c
854 (scm_procedure_documentation), procs.h (SCM_TOP_LEVEL), ramap.c
855 (scm_array_fill_int), scmsigs.c (scm_sigaction), stacks.c
856 (narrow_stack, scm_make_stack, scm_stack_id), symbols.c
857 (scm_string_to_obarray_symbol), throw.c (scm_catch,
858 scm_lazy_catch, scm_ithrow), unif.c (scm_make_uve, scm_array_p,
859 scm_array_set_x, scm_bit_set_star_x, scm_bit_count_star),
860 validate.h (SCM_VALIDATE_BOOL_COPY, SCM_VALIDATE_PROC): Replace
861 uses of SCM_TRUE_P (x) with SCM_EQ_P (x, SCM_BOOL_T).
863 2000-06-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
865 * eval.c (scm_badformalsp): New static function.
866 (SCM_CEVAL): Check arguments for procedure-with-setter closures.
867 (Thanks to Keisuke Nishida.)
869 The major reason for Guile's slow loading speed has been the fact
870 that a chain of Scheme level procedures has been evaluated for
871 every top-level symbol lookup during the first pass through the
874 The following is a kludge which I suggested four years ago, and
875 which I've repeatedly suggested since. Personally, I've never
876 been bothered by Guile's slow loading speed, so I thought I would
877 let someone else do it...
879 But since the new environments will be included first in
880 Guile-1.5, I thought it would make people happy to get the kludge
883 * modules.c: Added #include "libguile/vectors.h";
884 Added #include "libguile/hashtab.h";
885 Added #include "libguile/struct.h";
886 Added #include "libguile/variable.h";
887 Capture Scheme level `module-make-local-var!' to be used in the
888 standard eval closure.
889 (scm_standard_eval_closure): New primitive.
891 * modules.h (scm_standard_eval_closure): Declare.
893 * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
894 instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
896 * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
897 standard eval closures.
899 * variable.c: Code layout fixes.
901 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
903 * Makefile.am: Added LIBS line to libpath which accidentally
904 disappeared in the change of 2000-06-01.
905 (Thanks to Dale P. Smith.)
907 2000-06-03 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
909 * scmsigs.c (scm_segfault): Removed. (Was probably added by
910 mistake since it is not mentioned in ChangeLog.)
912 * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
913 avoid compiler warnings in gcc. (Does this work for other
916 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
918 * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
920 (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
921 SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1. It's not correct to take
922 the address of these expressions since they use SCM_VALIDATE_CELL.
923 (Thanks to Bernard Urban.)
925 * dynl.c: Changed #include <ltdl.h> --> #include
926 "libltdl/ltdl.h". (Thanks to Bill Schottstaedt.)
928 2000-06-01 Craig Brozefsky <craig@red-bean.com>
930 * Makefile.am: libguile_la_LDFLAGS gets -version-info args
931 from GUILE-VERSION definition of LIBGUILE version. Added to
932 libpath.h definitions for guileversion and libguileversion which
933 both get their values from GUILE-VERSION definition.
935 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
937 * numbers.h (SCM_BIGP): Don't use SCM_SMOB_PREDICATE in header
938 file: Code using numbers should not be required to include
941 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
943 * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
944 mit-pthreads.c, mit-pthreads.h: Deleted.
946 * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]: Drop
947 references to deleted files and fsu/mit thread support in
950 2000-05-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
952 * hooks.c (symbol_name, scm_create_hook): Restored the original
953 behaviour of scm_create_hook. Changing it was bad as Carl
954 R. Witty has pointed out.
956 * gc.c (scm_init_gc): We can still rely on scm_create_hook to
959 2000-05-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
961 * gc.c (scm_init_gc): Protect scm_after_gc_hook, since this will
962 soon not be done by scm_create_hook any longer.
964 * hooks.c (make_hook, print_hook, scm_create_hook,
965 scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
966 SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
967 scm_make_hook_with_name), init.c (scm_boot_guile_1): Hooks no
968 longer have names. As an intermediate solution, the name
969 predicate is emulated via object properties, but use of this
970 feature is deprecated.
972 * hooks.h (scm_free_hook): Removed, as it is never defined.
974 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
976 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
977 Un-deprecated since otherwise user code can't determine whether a
978 number fits into an inum any longer. The names should be changed
981 * numbers.c (scm_big2inum): Eliminated use of SCM_UNEGFIXABLE.
983 * tags.h (SCM_UNPACK_CAR): Deprecated.
985 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
987 * filesys.h (SCM_OPDIRP), fluids.h (SCM_FLUIDP, SCM_FLUID_NUM),
988 fports.h (SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP), hooks.h
989 (SCM_HOOK_ARITY), keywords.h (SCM_KEYWORDP, SCM_KEYWORDSYM),
990 numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
991 Replace SCM_UNPACK_CAR appropriately. Don't access cells via
992 SCM_{SET}?C[AD]R unless they are known to be cons cells.
994 * gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
995 init_heap_seg): Remove unused struct member variable 'valid'.
997 2000-05-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
999 * fports.c (fport_write), ports.c (scm_markstream, scm_port_mode,
1000 scm_print_port_mode), ports.h (SCM_OPPORTP, SCM_OPINPORTP,
1001 SCM_OPOUTPORTP, SCM_INPUT_PORT_P, SCM_OUTPUT_PORT_P, SCM_OPENP),
1002 procs.h (SCM_CLOSCAR), unif.h (SCM_ARRAY_NDIM, SCM_ARRAY_CONTP),
1003 variable.h (SCM_VARIABLEP): Replace SCM_UNPACK_CAR
1006 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1008 * gc.c (free_list_length), hash.c (scm_hasher), macros.c
1009 (scm_macro_type), objects.c (scm_class_of), options.c
1010 (scm_options), print.c (scm_iprin1), strports.c (st_seek), throw.c
1011 (SCM_LAZY_CATCH_P): Replace SCM_UNPACK_CAR appropriately.
1013 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1015 * eval.c (scm_macroexp, SCM_CEVAL, scm_force), tags.h: Replace
1016 SCM_UNPACK_CAR with SCM_CELL_TYPE or SCM_CELL_WORD_0.
1018 * eval.c (scm_force): Add documentation.
1020 * eval.c (scm_force, scm_cons_source): Don't access cells via
1021 SCM_{SET}?C[AD]R unless they are known to be cons cells.
1023 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1025 * strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
1026 (SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP): Deprecated.
1028 * gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT): Removed #ifdef
1029 nosve #endif conditionally compiled code.
1031 2000-05-23 Michael Livshin <mlivshin@bigfoot.com>
1033 * gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
1035 2000-05-22 Michael Livshin <mlivshin@bigfoot.com>
1037 * guile-doc-snarf.in: put the preprocessed file through sed to
1038 trim all lines to 1024 chars. I hope it doesn't break anybody's
1039 sed. we'll see. (note: this is lossy trimming, i.e. the spill
1040 isn't wrapped around but actually chopped off. this seemed to me
1041 safe because the current snarfer doesn't understand multi-line
1042 cookies anyway. in the long term, it would be nice not to depend
1043 on AWK for anything.)
1045 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
1046 the previous change to this macros, after deciding to torture the
1049 2000-05-21 Michael Livshin <mlivshin@bigfoot.com>
1051 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
1052 the yucky, ugly and nasty conditional compilation back. sorry,
1053 but it was either that or requiring GAWK to build Guile.
1054 (lots of places): removed the code that implemented the old GC
1057 * init.c (scm_boot_guile_1): removed the code conditioned on
1058 !GUILE_NEW_GC_SCHEME.
1060 * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
1062 * gc.c (scm_protect_object, scm_unprotect_object): change the
1063 implementation to more efficient (at least in the time complexity
1064 sense). the calls should now also be thread-safe -- I suspect
1065 that people expect them to be. (thanks to Han-Wen Nienhuys)
1066 (lots of places): removed the code that implemented the old GC
1069 * hashtab.c (scm_hash_fn_create_handle_x): add missing
1070 SCM_REALLOW_INTS before return. I really wonder about the
1071 possible interactions between hashtables, threads & GC. it
1072 doesn't look healthy at all.
1074 2000-05-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1076 * unif.c (scm_bit_count): Fixed the parameter checks. Thanks to
1079 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1081 * __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_): Added as a new
1082 debug option to verify all accesses to cells actually access
1083 objects on the heap.
1085 * gc.h (SCM_VALIDATE_CELL): Added. Only performs validation if
1086 SCM_DEBUG_CELL_ACCESSES is set to 1.
1088 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,

1116 * __scm.h (SCM_DEBUG_REST_ARGUMENT): Renamed from
1117 SCM_DEBUG_REST_ARGUMENTS in order to clarify that we don't test
1118 the actual arguments in the list, but rather the rest argument as
1119 a list of arguments.
1121 * validate.h (SCM_VALIDATE_REST_ARGUMENT): Added.
1123 * async.c (scm_noop), eval.c (scm_map, scm_for_each), list.c

1131 scm_dynamic_link, scm_init_dynamic_linking), dynl.h
1132 (scm_dynamic_link): Removed possibility to pass flags to
1133 scm_dynamic_link, as it had no effect anyway.
1135 * filesys.c (scm_fcntl): Made single optional rest argument into
1136 a standard optional argument.
1138 * hooks.c (scm_run_hook): A list of rest arguments is never
1141 * list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
1142 strings.c (scm_string_append): Don't perform half-hearted checks
1143 to see whether the rest argument forms a proper list any more, use
1144 SCM_VALIDATE_REST_ARGUMENTS instead.
1146 * ports.c (scm_close_all_ports_except): Accept empty list of rest
1149 * posix.c (scm_convert_exec_args), print.c (scm_simple_format):
1150 Simplify verification of rest argument.

1159 rest argument into a standard mandatory argument.
1161 2000-05-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
1163 * __scm.h: Added SCM_DEBUG as default debug option. (Thanks to
1164 Keisuke Nishida for the suggestion.) Added debug option
1165 SCM_DEBUG_REST_ARGUMENTS.
1167 * eval.c (scm_map, scm_for_each): Make sure all lists have the
1168 same length. Also, removed redundant parameter checks.

1174 * __scm.h: Improved explanation of giving options to make.
1176 * __scm.h (SCM_DEBUG_TYPING_STRICTNESS), tags.h
1177 (SCM_STRICT_TYPING, SCM_DEBUG_TYPING_STRICTNESS): Renamed
1178 SCM_STRICT_TYPING to SCM_DEBUG_TYPING_STRICTNESS and moved the
1179 corresponding declaration and comment to __scm.h.

1182 (scm_remainder, scm_modulo), numbers.h (SCM_SRS, SCM_MAKINUM,
1183 SCM_INUM): Removed conditionally compiled code for Turbo C.
1185 * gdbint.c (gdb_maybe_valid_type_p): Eliminated call to scm_tag.
1186 That check can be assumed to be redundant except for very rare

1189 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1191 * numbers.c (scm_logcount, scm_integer_length): Reordered
1194 2000-05-15 Gary Houston <ghouston@arglist.com>
1196 * stime.c (scm_strftime): don't reset TZ if zone is an empty
1197 string. append a "0" to the zone for TZ.
1199 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
1201 * numbers.c (scm_logbit_p, scm_bit_extract): Reordered dispatch
1204 (scm_bit_extract): Fixed handling of bignums.

1220 scm_output_port_p), print.c (scm_get_print_state), validate.h
1221 (SCM_VALIDATE_CHAR): Replace use of deprecated macros
1222 SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
1223 SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
1225 2000-05-14 Gary Houston <ghouston@arglist.com>
1227 * stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
1228 TZ environment variable so that the %Z format returns the zone
1229 from the input vector instead of the system default.
1231 from Keisuke Nishida:
1232 * fports.c (scm_setvbuf): minor docstring fix.
1233 * ports.h (scm_generic_fgets): obsolete prototype deleted.
1235 2000-05-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
1237 * __scm.h: Added new section for debugging options.
1239 (SCM_DEBUG_DEPRECATED): If 1, no deprecated code is included to
1240 help developers to get rid of references to deprecated code.
1242 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,
1243 SCM_FIXABLE, SCM_FLOBUFLEN): These macros are no longer provided
1244 as part of the interface and are marked as deprecated in the
1247 * numbers.c (scm_make_real, scm_make_complex): Inlined the
1248 corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
1251 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,
1252 SCM_REAL, SCM_IMAG, SCM_REALPART, scm_makdbl, SCM_SINGP,
1253 SCM_NO_BIGDIG, SCM_NUM2DBL, scm_dblproc): Deprecated.
1255 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1257 * gc.h (scm_cell, SCM_CELL_WORD, SCM_CELL_OBJECT,
1258 SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT): Scheme cells now consist
1259 of two scm_bits_t values instead of two SCM values, because it is
1260 legal for cell entries to hold values that are not scheme objects.
1262 (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
1263 Use SCM_SETC[AD]R to modify contents of pairs.

1267 * numbers.c (IS_INF, isfinite): Added FIXME comment.
1269 (scm_abs, scm_magnitude): Make these two independent of each
1270 other. scm_abs now reports an error if given a complex argument.
1272 (scm_istr2flo, scm_integer_p). Use SCM_REAL_VALUE instead of
1273 SCM_REALPART if the object is known to be real.
1275 (scm_init_numbers): No need to use SCM_NEWREAL macro for speed
1278 * numbers.h (SCM_SINGP): Set to 0 instead of SCM_BOOL_F.
1280 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>

1286 gh_scm2doubles), hash.c (scm_hasher), ramap.c (scm_array_fill_int,
1287 ramap_rp, scm_array_map_x), random.c (vector_scale,
1288 vector_sum_squares), unif.c (scm_make_uve, scm_array_p,
1289 scm_array_set_x): Use SCM_REAL_VALUE instead of SCM_REALPART if
1290 the object is known to be real. Use SCM_COMPLEXP instead of
1291 deprecated SCM_CPLXP. Use SCM_INEXACTP instead of deprecated
1294 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1296 * numbers.c: No need to include unif.h.
1298 (IS_INF): Returned to old test for now: x == x + 1 will not work
1299 for large numbers due to rounding errors.
1300 Thanks to Kalle Olavi Niemitalo.
1302 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1304 * numbers.c (scm_divbigdig): Removed outdated comment.
1306 (scm_number_to_string, scm_string_to_number, scm_number_p,
1307 scm_real_p, scm_integer_p, scm_inexact_p, scm_gr_p, scm_leq_p,
1308 scm_geq_p, scm_make_rectangular, scm_make_polar,
1309 scm_inexact_to_exact): Added comments.
1311 (add1, scm_init_numbers): Removed add1.
1313 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1315 * numbers.c (IS_INF): The new test is x == x + 1. The old test
1316 x == x/2 did not work for zero values. Thanks to Han-Wen Nienhuys
1319 (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
1320 scm_num2long, scm_num2long_long, scm_num2ulong): Reordered
1323 2000-05-09 Marius Vollmer <mvo@zagadka.ping.de>
1325 * scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
1326 SIGILL and SIGBUS signals. These signals are not continuable and
1327 must be handled for real right away.
1329 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1331 * numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,
1332 scm_real_part, scm_imag_part, scm_magnitude,
1333 scm_inexact_to_exact): Reordered dispatch sequence.
1335 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1337 * feature.c: No need to include "libguile/smob.h"
1339 (scm_loc_features, features, scm_add_feature, scm_init_feature):
1340 Removed variable 'scm_loc_features' as a pointer to the SCM value
1341 holding the features list. Using variable 'features' instead,
1342 which holds the interned pair. Thus, SCM_SETCDR can be used
1343 instead of pointer trickery.
1345 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1347 * alist.c (scm_acons): Use SCM{_SET}?_CELL_OBJECT as long as a
1348 cell is not known to be a valid pair.
1350 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1352 * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1): Removed
1353 ASRTSYNTAX. Using SCM_ASSYNT instead.
1355 (scm_m_body): Don't create a redundant cons cell.

1359 (bodycheck): Removed.
1361 * stacks.c (stack_depth, read_frame, read_frames): Removed
1362 redundant calculation of size, minimized some variable scopes.
1364 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1366 * pairs.c (scm_cons, scm_cons2): Use SCM{_SET}?_CELL_OBJECT as
1367 long as a cell is not known to be a valid pair.
1369 (scm_pair_p): Eliminated redundant SCM_IMP test.
1371 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1373 * eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,
1374 scm_deval_args): Eliminated redundant SCM_IMP tests.
1376 * hashtab.c (scm_ihashx, scm_sloppy_assx, scm_delx_x), weaks.c
1377 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
1378 scm_make_doubly_weak_hash_table): Fixed critical sections.
1379 Thanks to Keisuke Nishida.
1381 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1383 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
1384 Fixed some goto-related initialization bugs (introduced by me).
1386 2000-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
1388 * numbers.h (SCM_INUM0): Uses SCM_MAKINUM instead of SCM_PACK.
1390 * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj): Removed.
1392 (DYNL_FILENAME, DYNL_HANDLE): Use SCM_CELL... macros instead of
1395 (SET_DYNL_HANDLE): Added.
1397 (scm_dynamic_object_p): Simplified.
1399 (scm_dynamic_unlink, scm_dynamic_func): Changed comment. Deliver
1400 better error message when accessing unlinked dynamic objects.
1401 Eliminated call to get_dynl_obj.
1403 2000-05-03 Marius Vollmer <mvo@zagadka.ping.de>
1405 * scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
1406 be an array of function pointers instead of being a pointer to an
1407 array returning function. Thanks to Kalle Olavi Niemitalo!
1409 2000-05-03 Dirk Herrmann <D.Herrmann@tu-bs.de>
1411 * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
1412 (scm_divbigbig, scm_divbigint): Don't return zero any more to
1413 indicate that a division has a remainder, return SCM_UNDEFINED
1414 instead. It is improbable that anyone actually used these
1415 functions outside of numbers.c. For this reason and due to the
1416 change in behaviour the functions are static now. Thus, if
1417 surprisingly there are users of these functions they will at least
1420 * numbers.c: Removed #ifdef SCM_BIGDIG #endif in those functions,
1421 that already have a clean dispatch order. Note: SCM_BIGDIG is
1424 * numbers.c (scm_inexact_p): Simplified.
1426 * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
1427 scm_product, scm_num2dbl, scm_angle): Reordered dispatch
1428 sequence, thereby fixing some comparisons of SCM values with
1431 * numbers.c (scm_divide): Division by zero of inums leads to an
1432 error now. (Formerly, an infinite number was returned.)
1434 Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
1435 if a division has a remainder.
1437 2000-05-02 Gary Houston <ghouston@arglist.com>
1439 * Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).
1441 2000-05-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
1443 * numbers.c (scm_logtest, scm_division): Reordered dispatch
1444 sequence, thereby fixing some comparisons of SCM values with
1447 * numbers.h (scm_makdbl): Mark as deprecated at the point of
1450 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_double2scm,
1451 gh_doubles2scm), numbers.c (scm_istr2flo, scm_max, scm_min,

1459 call to scm_makdbl with a call to scm_make_real or
1460 scm_make_complex, depending on whether the imaginary part is known
1463 2000-05-01 Gary Houston <ghouston@arglist.com>
1465 * scmsigs.c: fix the definition of orig_handlers for the case
1466 that HAVE_SIGACTION is not defined (thanks to
1467 Kalle Olavi Niemitalo).
1469 * Makefile.am: remove include_HEADERS (was libguile.h)
1470 libguile.h: moved to top level directory.
1472 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1474 * numbers.c (SCM_SWAP): Moved to the top of the file to allow for
1477 * numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,
1478 scm_logxor): Reordered dispatch sequence, thereby fixing some
1479 comparisons of SCM values with integer constants.
1481 * number.c (scm_logtest): Removed some redundant SCM_{N}?IMP
1484 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1486 * numbers.c (scm_quotient, scm_remainder): Removed code that was
1487 conditionally compiled based on BADIVSGNS. BADIVSGNS does not
1488 occur anywhere else throughout guile.
1490 * numbers.c (scm_quotient): Fixed parameter number in error
1493 * numbers.c (scm_remainder): Reordered dispatch sequence.
1495 2000-04-25 Gary Houston <ghouston@arglist.com>

1503 (suggested by Jost Boekemeier).
1505 2000-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1507 * pairs.c (cxrs, scm_init_pairs): Simplify initialization of
1510 * procs.c (scm_init_iprocs), procs.h (scm_subr, scm_iproc,
1511 scm_dsubr, scm_init_iprocs): Removed.
1513 * procs.h (SCM_SUBRF, SCM_DSUBRF): Access the cell words
1514 directly instead of casting a cell to a C struct.
1516 2000-04-22 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1518 Better modularization of GC extensions through new C level GC
1521 * weaks.c (scm_weaks_prehistory): New function: Add

1533 * guardians.c (scm_guardian_gc_init): Turned into a hook function
1534 and added to scm_before_mark_c_hook.
1535 (scm_guardian_zombify): Turned into a hook function and added to
1536 scm_before_sweep_c_hook.

1539 Added #include "libguile/gc.h".
1541 * gc.h: Added #include "libguile/hooks.h".
1543 * gc.c: Removed #include "libguile/guardians.h".
1544 (scm_before_gc_c_hook, scm_before_mark_c_hook,
1545 scm_before_sweep_c_hook, scm_after_sweep_c_hook,
1546 scm_after_gc_c_hook): New C level hooks.
1547 (scm_after_gc_hook): New Scheme level hook.
1548 (scm_gc_sweep): Moved scanning of weak vectors to weaks.c.
1549 (scm_igc): Moved initialization of scm_weak_vectors and the call
1550 to scm_guardian_gc_init to respective module.

1576 the root build directory.
1578 * numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG
1579 instead of SCM_ASSERT (0, ...). (Some compilers will complain
1580 about control reaching end of function otherwise, and, besides,
1581 the new code is not less clear.)

1892 * async.h: kill the scm_async_t struct. having a heap cell

1964 separate loop after processing all the currently known live
1965 guardians, so as to not introduce order dependencies (thanks to
1966 Gary Houston). note that the order problems are still there if
1967 some guardians are themselves zombies, but that's a sick case that
1968 I'm not going to worry about.
1969 also, make another outer loop to process zombified
1970 guardians (which are uncovered while marking zombies).

2077 scm_reverse_lookup), dynl.c (scm_dynamic_link): Don't use C
2078 operators to compare SCM values.
2080 * debug.c (scm_make_debugobj), debug.h (SCM_DEBUGOBJ_FRAME,
2081 SCM_SET_DEBUGOBJ_FRAME): Update SCM_{SET_}?DEBUGOBJ_FRAME to
2082 access raw cell data with SCM_{SET_}?CELL_WORD_1.
2084 * debug.c (scm_make_debugobj): Don't use SCM_SETCAR to set types.
2086 * debug.c (scm_make_memoized), dynl.c (scm_dynamic_link): Smob
2087 data is of type scm_bits_t.
2089 2000-03-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
2091 * gdbint.c (gdb_maybe_valid_type_p), guardians.c (TCONC_EMPTYP,
2092 scm_guardian_zombify): Use SCM_EQ_P to compare SCM values.
2094 * guardians.c (GUARDIAN): Use SCM_CELL_WORD_1 for raw data.
2096 2000-03-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
2098 * ports.h (scm_port): Change type of stream member to scm_bits_t.
2100 * gdbint.c (unmark_port, remark_port), ports.c (scm_markstream),
2101 strports.c (st_resize_port, scm_mkstrport), vports (sf_flush,
2102 sf_write, sf_fill_input, sf_close, scm_make_soft_port): Since
2103 streams are now of type scm_bits_t, SCM streams have to be
2106 * ports.h (SCM_SETPTAB_ENTRY, SCM_SETSTREAM): Cast input to
2109 2000-03-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2111 * coop-defs.h (struct coop_t): Added `sto'-field again because of
2112 binary compatibility---let's remove it next time we alter some
2115 * coop.c (coop_quitting_p, coop_cond_create, coop_mutex_create,
2116 coop_mother, coop_child): New variables.
2117 (mother): New function.
2118 (coop_create): New thread spawning mechanism which uses a "mother
2119 thread". The "dummy" pthreads aren't healthy enough to give birth
2120 to new threads since Linux threads thinks they are asleep.
2122 * coop-defs.h (struct coop_t): Removed dummy_mutex.
2124 * coop-defs.h, coop-threads.c (struct coop_t): Eliminate
2125 `sto'-field when GUILE_PTHREAD_COMPAT is enabled.
2127 2000-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
2129 * arbiters.c (scm_make_arbiter), async.c (scm_async), dynwind.c
2130 (scm_internal_dynamic_wind): Smob data is always of type
2133 * arbiters.c (SCM_ARB_LOCKED, SCM_LOCK_ARB, SCM_UNLOCK_ARB):
2134 Access the locking information in cell entry 0 with
2135 SCM_{SET_}?CELL_WORD_0 instead of SCM_*CAR.
2137 * async.c (scm_run_asyncs): Use SCM_NULLP to test for the empty
2140 * dynwind.c (scm_dowinds): Use SCM_EQ_P to compare SCM values.
2142 * ports.h (SCM_PTAB_ENTRY, SCM_SETPTAB_ENTRY): Access the ptab
2143 entry data using SCM_{SET_}?CELL_WORD_1 instead of SCM_{SET}?CDR.
2145 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2147 * alist.c (scm_sloppy_assq, scm_assq), eq.c (scm_eq_p, scm_eqv_p,
2148 scm_equal_p), list.c (scm_ilength, scm_last_pair, scm_reverse,
2149 scm_sloppy_memq, scm_delq_x, scm_delq1_x), tags.h (SCM_UNBNDP):
2150 Don't use C operators == and != to compare SCM values, use
2153 * boolean.c (scm_boolean_p): Use SCM_BOOLP to determine whether a
2154 SCM value is equal to #t or #f.
2156 * eq.c (scm_eqv_p, scm_equal_p): Don't use SCM_CAR to access the
2157 cell type entry of non immediate objects of unknown type. Use
2158 SCM_CELL_TYPE instead.
2160 * gh_data.c (gh_scm2bool, gh_module_lookup), list.c
2161 (scm_sloppy_memv, scm_sloppy_member, scm_delv_x, scm_delete_x,
2162 scm_delv1_x, scm_delete1_x), scmsigs.c (scm_sigaction): Use
2163 SCM_FALSEP and SCM_TRUE_P to compare SCM values against #f and
2166 * list.c (scm_listify): Use SCM_UNBNDP to test for an unbound
2169 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2171 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread,
2172 scm_make_mutex, scm_make_condition_variable): Cast data to
2173 scm_bits_t in SCM_SET_CELL_WORD and SCM_NEWSMOB macros.
2175 * coop.c (coop_create): Set `specific' field, not `data' to NULL.
2177 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2179 * smob.h (SCM_NEWSMOB, SCM_NEWSMOB2, SCM_NEWSMOB3, SCM_SMOB_DATA,
2180 SCM_SET_SMOB_DATA, SCM_TC2SMOBNUM, SCM_SMOBNUM): To access smob
2181 data, use SCM_{SET_}?CELL_TYPE or SCM_{SET_}?WORD_[1-3].
2183 Note that this implies that smob data has always to be passed as
2184 values of type scm_bits_t.
2186 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2188 * threads.c (scm_init_threads): Pass 0 size to scm_make_smob_type
2189 for scm_tc16_thread. As the current COOP threads are written, GC
2190 is not supposed to manage storage for threads.
2192 * error.c (scm_error): Don't try to throw an error if
2193 scm_gc_heap_lock is true.
2195 * coop.c (coop_finish): New function. Called at exit.
2196 (coop_aborthelp): Free thread structures when threads die.
2197 Finished LinuxThreads compatibility support => COOP threads now
2198 mesh with LinuxThreads.
2200 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread):
2201 Changed SETCDR --> SET_CELL_WORD_1.
2203 * coop-threads.c (scheme_launch_thread): Set word 1 of handle to 0
2206 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2208 * boolean.h (SCM_TRUE_P): New macro.
2210 * boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP), pairs.h
2211 (SCM_NULLP, SCM_NNULLP): Use SCM_EQ_P to compare SCM values.
2213 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2215 * continuations.h (SCM_CONTREGS, SCM_SET_CONTREGS): New macros to
2216 access continuation data.
2218 (SCM_SETJMPBUF): Deprecated. Use SCM_SET_CONTREGS instead.
2220 (SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE, SCM_BASE, SCM_SEQ,
2221 SCM_DFRAME): Use SCM_CONTREGS instead of SCM_CHARS to access
2224 * continuations.c (scm_make_cont), init.c (start_stack),
2225 root.c (scm_internal_cwdr): Use SCM_SET_CONTREGS instead of
2228 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2230 * symbols.h (SCM_LENGTH, SCM_SETLENGTH): Access the length field
2231 of strings and symbols by using SCM_{SET_}?CELL_WORD_0.
2233 (SCM_CHARS, SCM_UCHARS, SCM_SETCHARS): Use SCM_{SET_}?CELL_WORD_1
2234 to access the char * field of strings and symbols.
2236 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2238 * gc.h (SCM_NEWCELL, SCM_NEWCELL2): Use SCM_SET_CELL_TYPE to set
2239 the type entry of a new cell. Added a comment about things to
2240 remember when updating the list of free cells.
2242 (SCM_FREEP, SCM_MARKEDP): Use SCM_CELL_TYPE to access the type
2245 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2247 * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR): Use
2248 SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT. This change implies that
2249 with strict type checking enabled these macros will only work if
2250 given valid SCM parameters.
2252 (SCM_GCCDR): Moved to tags.h.
2254 * tags.h (SCM_GCCDR): Moved here from pairs.h.
2256 2000-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
2258 * tags.h (SCM2PTR, PTR2SCM): Moved to gc.h.
2260 * pairs.h (scm_cell, SCM_CELLPTR, SCM_CELL_WORD*, SCM_CELL_OBJECT*,
2261 SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*, SCM_CELL_TYPE,
2262 SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK, SCM_PTR_GT,
2263 SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC, SCM_NEWCELL,
2264 SCM_NEWCELL2): Moved to gc.h.
2266 (SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR, SCM_SETAND_CDR,
2267 SCM_SETOR_CAR, SCM_SETOR_CDR): Moved to gc.h. These names should
2268 be changed, though, since the macros are not only pair related.
2272 * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,
2273 SCM_CELL_OBJECT*, SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*,
2274 SCM_CELL_TYPE, SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK,
2275 SCM_PTR_GT, SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC,
2276 SCM_NEWCELL, SCM_NEWCELL2, SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR,
2277 SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR): Moved here from
2280 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2282 * tags.h (SCM_STRICT_TYPING): New macro that, if defined,
2283 activates strict compile time type checking for variables of
2285 (SCM, SCM_PACK, SCM_UNPACK): Define according to whether
2286 SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
2287 (SCM_EQ_P): Defined as a macro equivalent for eq?.
2289 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2291 * tags.h (SCM_POINTERS_MUNGED): Removed.
2293 * gc.c (scm_gc_sweep, init_heap_seg): Removed use of
2294 SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
2296 2000-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
2298 * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
2299 SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
2300 SCM_SET_CELL_TYPE): Added a set of low level macros for accessing
2302 (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
2304 * procs.h, procs.c: Instead of SCM_{SET_}?CELL_WORD[12], use the
2305 newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
2307 2000-03-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2309 * tags.h: Disabled definition of SCM_VOIDP_TEST.
2311 Defining SCM as void * introduces problems which haven't been
2312 handled yet. Developers who work with these issues can enable it
2313 in their working copies.
2315 Disabling this definition exposes a set of newly introduced and
2316 older misuses of types which causes warning messages during
2317 compilation. We'll fix this successively.
2319 * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
2320 in order to obtain a value of type SCM.
2321 (scm_cellp): Updated with new changes to scm_mark_locations.
2323 * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
2325 * continuations.c (scm_make_cont): Removed cast of size_t into
2328 * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
2330 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2332 * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for
2333 shifting, not constant. Thanks to Dale P. Smith.
2335 * numbers.c (scm_sum, scm_difference): Don't test a SCM value
2336 for being less than zero. Decode it to a C value first. Again,
2339 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2341 * numbers.h, ramap.c, struct.h, vectors.h: Don't use SCM2PTR for
2342 non scheme values. If raw data is stored in SCM variables, it has
2343 to be accessed using SCM_UNPACK until a better solution is found.
2345 2000-03-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2347 * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
2348 pointer-arithmetic induced by the SCM_PACK/UNPACK change.
2350 * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
2352 * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
2354 * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
2356 * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
2358 * async.c, __scm.h: Removed lots of the old async click logic. It
2359 is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
2360 __scm.h. Let's try this out and dump the old code after the
2361 threads reorganization.
2362 (set-tick-rate, set-switch-rate): Conditionally removed.
2364 2000-03-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2366 * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
2367 made SCM values into pointers. This turned an arithmetic
2368 computation of the address of the vcell into a pointer-arithmetic
2369 one, thereby screwing up marking of structs.
2370 Bugfix 2: Removed incompletely introduced loop variable `j' used
2371 when protecting the tail array of a struct.
2373 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2375 * struct.h (SCM_STRUCT_DATA): Don't cast SCM values to pointers.
2377 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2379 * symbols.h, symbols.c (scm_strhash): Declare the string
2380 parameter as constant, since it is not modified.
2382 * symbols.c (scm_intern_obarray_soft,
2383 scm_sysintern0_no_module_lookup): Can now pass constant strings
2384 to scm_strhash without need for casting.
2386 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2388 * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS): Don't cast SCM
2389 values to pointers. Use SCM2PTR instead.
2391 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2393 * async.c (scm_set_tick_rate, scm_set_switch_rate): Don't unpack
2394 results of SCM_INUM.
2396 2000-03-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2398 * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
2399 GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
2400 GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
2402 * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
2403 min_yield_fraction, min_yield, adjust_min_yield): Renamed from
2404 SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
2405 gc_trigger, adjust_gc_trigger.
2407 * gc.c (alloc_some_heap): Further improvement of minimal heap size
2409 (SCM_MAX): New macro.
2410 (scm_freelist_t): New field: collected_1. Previous amount of
2412 (gc_sweep_freelist_finish): Trigger based on two last values of
2413 freelist->collected to avoid unnecessary allocation due to
2415 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
2416 Adjusted to 45000 cells, 40% and 40%. Gives quick startup
2417 without extra heap allocation.
2419 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2421 * numbers.h (SCM_MAKINUM): The parameter to SCM_MAKINUM should
2422 already be a C value. No need to unpack it.
2424 * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t
2425 if we know it fits into an inum.
2427 * ramap.c (ramap_rp): An scm_tc7_[ui]vect object does point to a
2428 field of long values. In contrast, SCM_VELTS accesses a field of
2431 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2433 * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
2435 (scm_gc_yield_1): New variable: Holds previous yield. Used to
2436 make better judgements.
2437 (gc_sweep_freelist_finish): Inserted explanation of use of
2440 * print.h, stacks.h, options.c, options.h: Changed C++
2443 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2445 * tags.h (SCM2PTR, PTR2SCM): Use SCM_PACK / SCM_UNPACK correctly.
2447 * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
2448 SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS): Use SCM_PACK /
2449 SCM_UNPACK / SCM2PTR correctly.
2451 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2453 * gc.c (adjust_gc_trigger): Improved documentation.
2454 (alloc_some_heap): Since gc_trigger is used against
2455 freelist->collected, this is the value which should be used to
2456 predict minimum growth.
2458 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2460 * eval.h: Fix mixup of packed/unpacked SCM values. (Thanks
2461 Thien-Thi Nguyen for the patch.)
2463 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2465 * numbers.c (scm_ash): Fixed typing problems with the second
2466 parameter and added some documentation. (Thanks Thien-Thi Nguyen
2467 for indicating the problem.)
2469 2000-03-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2471 * gc.c, gc.h (scm_gc_yield): New variable.
2472 (adjust_gc_trigger): Use scm_gc_yield.
2473 (alloc_some_heap): Use scm_gc_yield instead of
2474 scm_gc_cells_collected.
2476 * coop-threads.c: Addd #include "root.h", #include "strings.h".
2478 * debug.c: Added #include "root.h". (Thanks to Thien-Thi Nguyen.)
2480 * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
2481 trigger adjustmeant: Take yield (freed cells) for all freelists
2483 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
2484 to 50000 cell heap with 45% trigger.
2485 (scm_gc_cells_collected): Reintroduced.
2486 (SCM_HEAP_SIZE): New macro.
2487 (scm_gc_sweep): Reintroduced correct computation of
2488 scm_cells_allocated.
2489 (scm_freelist_t): Corrected commentary for field `cluster_size':
2490 Clustersize counts objects, not cells; New member
2491 `clusters_allocated'.
2493 2000-03-19 Michael Livshin <mlivshin@bigfoot.com>
2495 * *.[hc]: add Emacs magic at the end of file, to ensure GNU
2498 2000-03-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2500 * threads.h: Added #include "libguile/throw.h". (Thanks to
2503 2000-03-18 Michael Livshin <mlivshin@bigfoot.com>
2505 * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
2506 names, anyone got any better ones?)
2508 * gc.h: (typedef struct scm_freelist_t) remove from here.
2510 * gc.c: (CELL_UP, CELL_DN) made these macros take additional
2511 parameter (the span).
2512 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
2513 (typedef struct scm_freelist_t) moved here from gc.h, it had no
2514 business being externally visible.
2515 (typedef struct scm_heap_seg_data_t) renamed from
2516 scm_heap_seg_data, to be style-compliant.
2517 (scm_mark_locations) if the possible pointer points to a
2518 double-cell, check that it's properly aligned.
2519 (init_heap_seg) align double-cells properly, work with the
2520 assumption that the segment size divides cleanly by cluster size.
2521 (round_to_cluster_size) new function.
2522 (alloc_some_heap, make_initial_segment) use round_to_cluster_size
2523 to satisfy the new init_heap_seg invariant.

2572 2000-03-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
2574 * genio.h: removed. (Only content was '/* delete me */'.)

2582 2000-03-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2584 * gc.c, gc.h: Cleanup of the change of 2000-03-15.
2585 Cluster sizes are now independent of GC trigger values.
2586 GUILE_GC_TRIGGER_n can now specify a relative trigger value:
2587 A negative integer gives fraction of total heap size in percent.
2588 (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
2590 * init.c (scm_boot_guile_1): Introduced new variable
2591 GUILE_MAX_SEGMENT_SIZE; New environment variable names:
2592 GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
2593 GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
2595 2000-03-16 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2597 * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
2598 freeing of segment work with the new GC scheme. (Thanks to
2599 Michael Livshin.) Oops, also happened to make GUILE_NEW_GC_SCHEME
2600 the default, but I'll let this change stay in CVS Guile since this
2601 code is not expected to contain serious bugs.
2603 2000-03-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2605 * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
2607 (scm_free_list_length): New procedure (GUILE_DEBUG).
2608 Fixed a small but serious bug introduced by the previous change.
2610 * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
2611 loop and declare as register.
2613 * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
2616 Wed Mar 15 08:27:04 2000 Greg J. Badros <gjb@cs.washington.edu>
2618 * fluids.c: Docstring patch from Keisuke Nishida. Some
2619 reindentation, too, and a couple formals renamed. Should
2620 fluid-set! return UNSPECIFIED instead of a value?
2622 Wed Mar 15 08:24:58 2000 Greg J. Badros <gjb@cs.washington.edu>
2624 * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
2625 generate the latter from the concrete listing of the former. Then
2626 make guile-procedures.txt depend on DOT_DOC_FILES instead of
2627 *.doc, so that rebuilding it works.
2629 Wed Mar 15 08:12:14 2000 Greg J. Badros <gjb@cs.washington.edu>
2631 * libguile.h: Include libguile/validate.h. Thanks Keisuke Nishida!
2633 * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
2634 with nothing and \n, respectively. Thanks Keisuke Nishida for
2635 noticing this problem.
2637 2000-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2639 * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
2640 new way of allocating heap. It makes Guile fast, but still
2643 * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
2644 allocating heap. The basic idea is to trigger GC every Nth
2645 allocated cell and grow heap when free list runs out. The scheme
2646 has been extended so that GC isn't triggered until all remaining
2647 cells are used. The implementation is also prepared for
2648 development in the direction of POSIX threads.
2650 * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
2651 SCM_EXPHEAP should return half of the heap size.
2653 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2655 The following change to init.c is only enabled if Guile was
2656 configured with --enable-guile-debug.
2658 * init.c (scm_i_getenv_int): New function.
2659 (scm_boot_guile_1): Use the environment variables
2660 GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
2661 they exist. (This may be replaced by a Scheme level mechanism in
2664 * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
2665 scm_assoc. (Thanks to Keisuke Nishida.)
2667 2000-03-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2669 * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
2670 scm_nil, scm_t. (Thanks to Keisuke Nishida.)
2672 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2674 * init.c (scm_boot_guile_1): Use same initial segment size for
2675 1-word and 2-word segments. Having the smaller size causes Guile
2676 to GC too often. Obviously something needs to be done to allow
2677 for a smaller 2-word segment without this to happen. (The amount
2678 of heap for each type should be automatically adapted to the
2679 application somehow.)
2681 [Almost all of these changes should be documented in the NEWS
2684 * gc.h (scm_freelist_t): New type.
2686 * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
2688 * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
2689 all of Guile basics fits into one segment and there suitable room
2691 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
2693 (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
2694 Freelists now contains information about object span, cells
2695 collected and amount of cells in heap segments belonging to the
2697 (scm_heap_size, scm_gc_cells_collected): Removed.
2699 * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
2701 * Makefile.am (libguile_la_LDFLAGS): Bumped library version
2704 * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
2705 numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
2706 rewrite of handling of real and complex numbers.
2707 (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
2708 removed along with the support for floats. (Float vectors are
2711 * tags.h (scm_tcs_bignums): Removed.
2712 (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
2713 Use SCM_BIGSIGN(x) to test for sign!
2714 (scm_tc16_big): The new bignum type.
2715 (SCM_REAL_PART, SCM_IMAG_PART): Removed.
2717 * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
2718 (scm_makdbl): Deprecated.
2719 (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
2720 (SCM_SINGP): Deprecated.
2722 (SCM_INEXP, SCM_CPLXP): Deprecated.
2723 (SCM_INEXACTP, SCM_COMPLEXP): New macros.
2724 (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
2725 SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
2726 (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
2727 for doubles and complex numbers.
2728 (SCM_REAL_VALUE): New selector for doubles.
2729 (scm_double_t, scm_complex_t): New types.
2732 * numbers.c (scm_floprint, scm_floequal): Removed.
2733 (scm_print_real, scm_print_complex, scm_real_equalp,
2734 scm_complex_equalp): New functions.
2736 * unif.c (scm_makflo): Removed.
2738 * smob.h (SCM_SMOB_PREDICATE): New macro.
2739 (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
2740 SCM_RETURN_NEWSMOB3): New macros.
2742 1999-11-21 Michael Livshin <mlivshin@bigfoot.com>
2744 The following changes implement primitive support for double cells
2745 (i.e. four-word cells) and change the representation of some
2746 things to multi-cells instead of cons+malloc. (Applied and
2749 * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
2750 (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
2751 multi-cell access macros (used by the ones below).
2752 (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
2755 * gc.c (scm_freelist2): multi-cell freelists.
2756 (inner_map_free_list): map_free_list, parameterized on ncells.
2757 "nn cells in segment mm" was misleading for ncells > 1; changed to
2758 "objects". still print cells too, though.
2759 (scm_map_free_list): rewritten using inner_map_free_list.
2760 (scm_check_freelist): get freelist as parameter, since now we have
2762 (scm_debug_newcell2): multi-cell variants of
2764 (scm_gc_for_newcell): take ncells and freelist pointer as
2766 (scm_gc_mark): add case for tc7_pws (procedures with setters are
2768 (scm_gc_sweep): don't free the float data, since it's not malloced
2770 (init_heap_seg): didn't understand what n_new_objects stood for,
2771 so changed to n_new_cells.
2772 (make_initial_segment): new function, makes an initial segment
2773 according to given ncells.
2774 (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
2776 * numbers.c (scm_makdbl): no malloc'ing needed, so the
2777 {DEFER,ALLOW}_INTS thing removed.
2779 * numbers.h (struct scm_dbl): changed to represent a double cell,
2780 with the number in the second half.
2782 * dynwind.c: changed the wind-guards representation to double
2785 * procs.c, procs.h: changed the procedure-with-setter representation
2788 * async.c, async.h: made async representation a double cell.
2790 * dynl.c: made dynamic_obj representation a double cell.
2792 2000-03-13 Gary Houston <ghouston@arglist.com>
2794 * ports.c (flush_void_port): renamed to flush_port_default.
2795 (end_input_void_port): renamed to end_input_default.
2797 * init.c (scm_standard_stream_to_port): create a void port instead
2798 of opening /dev/null if the standard file descriptors are bad.
2799 advantages: no portability problems, doesn't waste a file descriptor,
2800 simplifies the code (thanks to Marius for the idea).
2802 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
2804 * void ports: make reading from a void port give EOF instead of
2806 * ports.c (s_scm_sys_make_void_port): modified docstring.
2807 (fill_input_void_port): new proc.
2808 (scm_init_ports): set up fill_input_void_port.
2809 * ports.c (scm_port_non_buffer): new proc.
2810 (scm_void_port): call scm_port_non_buffer.
2812 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
2813 which was incorrectly appended.
2815 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2817 * guile-doc-snarf.in: Don't use absolute path for `sed'. (Note
2818 that we can't use autoconf for this. Autoconf itself relies on
2819 the existence of `sed' somewhere on your path.) (Thanks to Dirk
2822 2000-03-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2824 * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
2825 EXTRA_libguile_la_SOURCES.
2827 * iselect.h: Always declare scm_internal_select.
2829 * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
2830 end. Also let scm_internal_select be a real function also when
2833 * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
2835 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2837 * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
2838 SCM_ASYNC_TICK. (This is a preparation for POSIX threads support,
2839 and kind of an experiment: Will this cause problems?)
2841 Sun Mar 12 13:26:30 2000 Greg J. Badros <gjb@cs.washington.edu>
2843 * Makefile.am: Added *.doc to DISTCLEANFILES.
2845 2000-03-12 Gary Houston <ghouston@arglist.com>
2847 * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
2848 the fdes is valid before doing anything else. check that
2849 the file descriptor supports the modes required.
2850 (scm_fport_buffer_add): don't throw an error if fstat doesn't
2851 work: just use the default buffer size.
2853 * throw.c: change an outdated comment about scm_internal_catch
2854 BODY: it doesn't take a jumpbuf arg.
2856 * init.c (scm_standard_stream_to_port): install a handler in case
2857 scm_fdes_to_port throws an error. don't check here whether the
2858 file descriptor is valid, since scm_fdes_to_port will do that.
2859 set the revealed count depending on whether the port got the
2860 standard file descriptor.
2861 (stream_body_data): new type.
2862 (stream_body, stream_handler): new procs.
2864 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2866 * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
2867 Renamed from SCMWORD.
2869 * tags.h (SCM_NCELLP): Removed (SCMWORD).
2871 * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
2873 * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
2874 feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,
2875 hash.c, keywords.h, macros.c, numbers.c, numbers.h, objects.c,
2876 objects.h, options.c, pairs.h, ports.c, ports.h, print.c,
2877 procs.h, ramap.c, read.c, smob.c, smob.h, srcprop.h, stacks.c,
2878 stacks.h, strports.c, struct.c, struct.h, tag.c, tags.h,
2879 throw.c, unif.c, unif.h, variable.h, vectors.h, weaks.c,
2880 weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
2881 SCM_ASSCM, SCM_ASWORD, SCM_CARW).
2883 * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
2885 * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
2886 tags.h: Fixed copyright notices.
2888 * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
2890 2000-03-12 Marius Vollmer <mvo@zagadka.ping.de>
2892 * init.c (scm_standard_stream_to_port): Check whether the file
2893 descriptor is valid and substitute "/dev/null" when not.
2895 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2897 * coop-defs.h (struct timespec): Conditionally defined.
2899 * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
2902 * readline.c (match_paren): Bugfix: First arg to select is not
2903 number of descriptors but the number of the highest descriptor +
2906 This is a preliminary attempt at a cleanup of the threads support
2907 code. It moves things to better places, makes arguments more
2908 consistent with the POSIX API (which is used in GNOME's glib), and
2909 adds new functionality.
2911 * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
2913 * coop-defs.h (scm_mutex_trylock): New macro: alias for
2915 (scm_cond_init): Changed definition to
2916 coop_new_condition_variable_init.
2918 * coop.c: #include <errno.h>
2919 (coop_timeout_qinsert): Moved here from iselect.c
2920 (coop_new_mutex_init, coop_new_condition_variable_init): New
2921 functions. The strange names are temporary. Use scm_mutex_init
2922 and scm_cond_init instead.
2923 (coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
2924 is ANSI C, but should we check for individual error codes in
2926 (coop_condition_variable_timed_wait_mutex): New function.
2927 (coop_key_create, coop_setspecific, coop_getspecific,
2928 coop_key_delete): New functions.
2930 * iselect.c (coop_timout_qinsert): Moved to coop.c
2932 2000-03-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2934 * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
2935 SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
2937 * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
2940 * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
2941 SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
2942 proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
2944 * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
2947 2000-03-11 Dale P. Smith <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
2949 * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
2950 scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
2951 logical functions from SCM.
2953 (logand, logior, logxor, logtest, logbit?): Extended scheme
2954 logical functions to use bignums from SCM.
2956 (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
2957 lognot from using bignums.
2959 Thu Mar 9 11:33:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2961 * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
2962 eliminating some warnings.
2964 * unif.c, strports.c, print.c, options.c: Fix some warnings on
2967 * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
2968 what the scm_return_first* functions do.
2970 2000-03-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
2972 * libguile/*.[ch]: make a distinction between SCM as a generic
2973 name for a Scheme object (now a void*), and SCM as 32 bit word for
2974 storing tags and immediates (now a long int). Introduced
2975 SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
2976 code in the process: arbiter.c (use macros), unif.c (scm_array_p),
2978 Wed Mar 8 10:15:59 2000 Greg J. Badros <gjb@cs.washington.edu>
2980 * numbers.c: Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
2981 various logXXX primitives. Thanks Eric Moore!
2983 Tue Mar 7 08:05:22 2000 Greg J. Badros <gjb@cs.washington.edu>
2985 * run-test, remaining-docs-needed: Added these scripts. The
2986 second one is only temporary until the docstring additions are
2987 complete. run-test may best live on, but is here mostly for
2988 convenience and awareness for now.
2990 * hash.c: Docs, minor cleanup patch from Dirk Herrman.
2992 Thu Mar 2 16:06:58 2000 Greg J. Badros <gjb@cs.washington.edu>
2994 * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
2995 displaying the expected type. Use SCM_LISTn in a couple places
2996 instead of scm_cons-ing by hand.
2998 * __scm.h: Added SCM_ASSERT_TYPE macro.
3000 * validate.h, scm_validate.h: Added the former, as a renamed
3001 version of the latter with SCM_ASSERT_TYPE used in
3002 SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
3004 * Makefile.am: Rename scm_validate.h to validate.h.
3006 * *.c, *.h: Include validate.h, not scm_validate.h (old name's
3007 prefix was superfluous).
3009 Thu Mar 2 15:33:12 2000 Greg J. Badros <gjb@cs.washington.edu>
3011 * hashtab.c: Improved documentation for lots of functions. Added
3012 handwritten docs for `hash-fold'.
3014 Thu Mar 2 15:13:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3016 * list.c: Added hand-written docs for `del{q,v,ete}1!'.
3018 Thu Mar 2 12:38:30 2000 Greg J. Badros <gjb@cs.washington.edu>
3020 * list.c: Moved append docs to append! Thanks Dirk Hermann. Also,
3021 added append docs from R4RS.
3023 * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
3024 Thanks Dirk Hermann!
3026 * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
3027 deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
3029 * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
3030 Drop use of SCM_P for function prototypes... assume an ANSI C
3031 compiler. Thanks Dirk Hermann!
3033 Sat Feb 19 12:20:12 2000 Greg J. Badros <gjb@cs.washington.edu>
3035 * ports.c: Made `set-port-column!' and `set-port-line!' each
3036 return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
3037 that caused a seg fault. Also fixed `set-port-column!'s
3038 docstring. Thanks Han-Wen Nienhuys for finding the bug!
3040 Sun Feb 13 19:11:42 2000 Greg J. Badros <gjb@cs.washington.edu>
3042 * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
3043 regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
3044 strings.c, variable.c: Added lots of documentation, cleaned up
3045 some existing documentation. Occasionally changed formal params
3046 to match docs. Also folded an #ifdef into the inners of a
3047 primitive instead of having two copies of the primitive
3048 (`get-internal-real-time', from stime.c)
3050 Sun Feb 13 18:12:19 2000 Greg J. Badros <gjb@cs.washington.edu>
3052 * ports.c: Added docs for primitives missing them. Written by
3055 Sun Feb 13 09:40:36 2000 Greg J. Badros <gjb@cs.washington.edu>
3057 * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
3058 just execing guile-func-name-check. Thanks Michael Livshin!
3060 Thu Feb 10 11:43:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3062 * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
3063 dead code. Patch from Michael Livshin.
3065 * guile-doc-snarf.in: Tweak to work with Sun/HP sh. Patch from
3068 2000-02-09 Gary Houston <ghouston@arglist.com>
3070 * init.c (scm_init_standard_ports): when stdout is a tty, make the
3071 current-output-port unbuffered by default. this is less confusing
3072 for interactive use. it was line-buffered because of a
3073 performance problem with unbuffered ports, but I think it will be
3076 2000-02-08 Gary Houston <ghouston@arglist.com>
3078 * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
3081 * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
3082 HAVE_TZNAME are defined, use an empty string instead of giving two
3083 spurious compile-time errors.
3085 Tue Feb 8 13:57:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3087 * ports.c: Doc patches from Richard Kim. Pasted from MIT Scheme.
3090 Mon Feb 7 09:07:31 2000 Greg J. Badros <gjb@cs.washington.edu>
3092 * macros.c: Doc patches from Richard Kim. Pasted from scm.texi.
3094 Sun Feb 6 20:26:21 2000 Greg J. Badros <gjb@cs.washington.edu>
3096 * pairs.c: Doc patches from Richard Kim. Pasted from MIT Scheme
3097 (which is GNU GPL'd).
3099 2000-01-31 Gary Houston <ghouston@arglist.com>
3101 * strings.h: don't use SCM_P. don't include <string.h>.
3102 * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
3104 * strings.c (scm_string_ref): make the 2nd argument compulsory.
3105 previously it defaulted to zero for no good reason that I can see.
3106 use a local variable for SCM_INUM (k). replace
3107 SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
3109 (scm_makfromstr): cosmetic changes.
3111 (scm_string): Accept only chars in the list, not strings, for
3112 conformance to R5RS (particularly for list->string, which is
3113 supposed to be the inverse of string->list.) remove
3114 SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
3115 scm_makstr handles the cell allocation. when reporting wrong-type
3116 arg, don't report the position as 1.
3118 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
3120 2000-01-29 Gary Houston <ghouston@arglist.com>
3122 * posix.c (scm_pipe): rewrote the docstring.
3124 * filesys.c (scm_select, retrieve_select_type, get_element,
3125 fill_select_type, set_element): modified so that Scheme
3126 "select" tests port buffers for the ability to provide input
3127 or accept output. Previously only the underlying file descriptors
3128 were checked. Rewrote the docstring.
3130 Thu Jan 27 10:14:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3132 * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
3133 from Gregg Reynolds. Thanks Gregg!
3135 Thu Jan 27 09:59:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3137 * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
3138 adding "x" prefix to the line so that guile-func-name-check
3139 doesn't complain unnecessarily.
3141 Wed Jan 26 17:33:52 2000 Greg J. Badros <gjb@cs.washington.edu>
3143 * throw.c: Factor out an #ifdef/#else/#endif choice more finely
3144 for maintainability.
3146 * strop.c: Documentation added by Gregg A. Reynolds. Pasted in
3149 Wed Jan 26 10:02:11 2000 Greg J. Badros <gjb@cs.washington.edu>
3151 * tag.c: Added doc for `tag', but mark as deprecated since Mikael
3152 suggests removing tag.c altogether (and using a new `class-of'
3155 * strings.c: Added documentation from Gregg A. Reynolds. Edited
3156 a bit by me to use FOO instead of @var{foo} and to have the
3157 summary come before preconditions on input. Also dropped trailing
3160 * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
3161 function with scm_make_subr_opt w/ last arg of 0 so it is not
3162 visible at the Scheme level. Mikael says that this is the right
3163 thing because the first arg to the proc is the guts of a compiled
3164 closure and shouldn't be exposed to the Scheme level.
3166 Tue Jan 25 17:15:47 2000 Greg J. Badros <gjb@cs.washington.edu>
3168 * sort.c: typo in comment fixed.
3170 * keywords.c: Added documentation.
3172 * guardians.c: Added documentation (could be better).
3174 * gc.c: Added docs for gc-set-debug-check-freelist.
3176 * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
3178 * boolean.c: Added docs for `not', `boolean?' (by hand).
3180 Tue Jan 25 13:28:56 2000 Greg J. Badros <gjb@cs.washington.edu>
3182 * random.c: Added documentation, from SLIB page:
3183 http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
3185 Mon Jan 24 17:50:20 2000 Greg J. Badros <gjb@cs.washington.edu>
3187 * variable.c, version.c: Added documentation, written by hand
3188 since I could not find anything already written that was
3191 2000-01-23 Gary Houston <ghouston@arglist.com>
3193 * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
3194 not defined (thanks to Richard Y. Kim).
3196 Thu Jan 20 13:00:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3198 * Makefile.in: Removed, this is auto-generated.
3200 Thu Jan 20 11:33:47 2000 Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
3202 * list.c: Put some variable initialization code at the point of
3203 declaration; Added a comment for list*; Formatting changes.
3205 * load.c: use SCM_NNULLP to make sure the end of a list is not
3208 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3210 * backtrace.c (scm_display_error_message): Bugfix: Don't use
3211 result of scm_list_p as C boolean.
3212 (scm_display_error_message, scm_set_print_params_x): Use new
3213 validation macros. (Thanks to Dirk Herrmann.)
3215 * net_db.c (scm_resolv_error): Cast result from hstrerror.
3217 * strports.c (st_end_input): Inserted parenthesis to get operator
3220 * list.h (scm_init_list): Removed SCM_P around prototypes.
3222 * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
3223 filesys.c, posix.c: Converted docstrings to ANSI C format and
3224 escaped " occurring inside string literals.
3226 Tue Jan 18 13:21:08 2000 Mikael Djurfeldt <mdj@r11n07-s.pdc.kth.se>
3228 * posix.c (scm_mknod): Escape " occuring inside docstring.
3230 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3232 * alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,
3233 evalext.c, filesys.c, gc.c, hash.c, hashtab.c, ioext.c,
3234 keywords.c, list.c, load.c, macros.c, net_db.c, numbers.c,
3235 objprop.c, ports.c, posix.c, print.c, procprop.c, procs.c,
3236 ramap.c, regex-posix.c, root.c, scmsigs.c, simpos.c, socket.c,
3237 stacks.c, stime.c, strings.c, strop.c, strports.c, struct.c,
3238 symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
3239 weaks.c: Converted docstrings to ANSI C format.
3241 * filesys.c (scm_chmod), simpos.c (scm_system), version
3242 (scm_version), vports (scm_make_soft_port): Escape " occuring
3245 Mon Jan 17 11:41:22 2000 Greg J. Badros <gjb@cs.washington.edu>
3247 * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
3248 SCM_VALIDATE_LONG_COPY
3250 * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
3251 SCM_VALIDATE_INUM_COPY to let bigger numbers be used. Rename a
3252 couple of formal arguments (and fix their uses) to make arguments
3253 match the documentation.
3255 2000-01-14 <mstachow@alum.mit.edu>
3257 * Makefile.am: Augment path when running guile-doc-snarf so
3258 guile-func-name-check is found.
3260 Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
3262 * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
3263 def, not SCM_MAKINUM(def); thanks Janis Bzerins!
3265 Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3267 * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
3268 the way guile-1.3.4 worked, but #if 0 out the version using
3269 SCM_VALIDATE_INUM_COPY for stricter testing.
3271 Tue Jan 11 18:24:18 2000 Greg J. Badros <gjb@cs.washington.edu>
3273 * guile-doc-snarf.in: Use new $fullfilename for running
3274 guile-func-name-check, and put "$fullfilename" and "$filename" in
3275 quotes at uses to make sure re-splitting on whitespace does not
3276 occur (so filenames w/ embedded whitespace would work okay, though
3277 I sure hope we never have to deal with that! :-) ). Thanks to
3278 Mikael for pointing out the source_dir != build_dir was broken.
3280 Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
3282 * scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
3283 SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
3284 SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
3285 macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
3288 * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
3289 then return whether it's an open port (was validating that it was
3290 an open port -- this was a bug I introduced back in December, but
3291 my careful reading of diffs caught it).
3293 * numbers.c: Recombine the two conditional-compilation paths for
3294 all the log* primitives -- they were split based on #ifndef
3295 scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
3296 some bugs and inconsistencies in the two sets of implementations.
3297 (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
3299 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
3300 SCM_VALIDATE_INUM_COPY once where it should've been used.
3302 * fluids.c (scm_internal_with_fluids): Use
3303 SCM_VALIDATE_LIST_COPYLEN.
3305 * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
3306 this is questionable as it relaxes type safety, but other changes
3307 were useful and all SCM_NUM2LONG's should probably be
3308 revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
3310 * evalext.c: line-break change on 1 line.
3312 * eval.c (nconc2last): Takes a non-empty list as its first
3313 argument, not just a list.
3315 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
3317 Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3319 * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
3320 net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
3323 * symbols.c (scm_sysintern0): Fixed the function name in a
3324 scm_misc_error invocation.
3326 * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
3327 use scm_return_first to ward off latent GC bug that Mikael caught.
3329 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
3330 used before but should've been.
3332 2000-01-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3334 * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
3335 SCM_FUNC_CAST_ARBITRARY_ARGS.
3337 Tue Jan 11 13:44:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3339 * guile-func-name-check.in: Added this script to statically check
3340 #define FUNC_NAME, #undef FUNC_NAME in the source.
3342 * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
3343 redundant comment, semicolon; caught by new guile-func-name-check
3346 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
3347 Caught by new guile-func-name-check-script.
3349 * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
3351 * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
3352 guile-func-name-check.
3354 * guile-doc-snarf.in: Run guile-func-name-check on the file before
3357 Tue Jan 11 11:31:10 2000 Greg J. Badros <gjb@cs.washington.edu>
3359 * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
3360 port function take const void*, not void*.
3362 Tue Jan 11 11:18:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3364 * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
3365 strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
3366 SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
3367 consistency with the other macros dealing with immediate
3368 characters. (Similar to INT -> INUM change a week or so ago).
3370 Tue Jan 11 10:41:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3372 * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
3373 net_db.c, read.c, socket.c: Update error messages to use ~A for
3374 %s, ~S for %S to work with new `simple-format' format and be
3375 standardized better.
3377 * print.h, print.c (scm_simple_format): Added `simple-format'
3378 primitive. It's the old scm_display_error, with ARGS now a rest
3379 parameter, and the destination first instead of last (and a couple
3380 new capabilities inspired by `format' -- #t as destination means
3381 current-output-port, #f means return the formatted text as a
3384 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
3386 * backtrace.c (scm_display_error_message): Rewrote to use
3387 scm_simple_format() procedure.
3389 * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
3391 2000-01-09 Marius Vollmer <mvo@zagadka.ping.de>
3393 Finally applied the libltdl patch from Thomas Tanner, with slight
3396 * DYNAMIC-LINKING: Removed because it is obsolete.
3397 * dynl.c: Use ANSI prototypes.
3398 (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
3399 * scmconfig.h.in: Do not change, as it is automatically generated.
3401 1999-07-25 Thomas Tanner <tanner@ffii.org>
3403 * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
3405 * Makefile.am: likewise, add INCLTDL (libltdl headers) to
3406 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
3408 * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
3409 * guile.c: register preloaded modules
3410 * scmconfig.h.in: remove obsolete symbols
3412 2000-01-09 Gary Houston <ghouston@arglist.com>
3414 * These changes should make it unnecessary to call tzset from
3415 Scheme after modifying the TZ environment variable, even if the
3416 system date facilities cache the value.
3417 * stime.c (setzone, scm_localtime): added comments.
3418 (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
3419 (setzone): don't call tzset.
3420 (restorezone): call tzset only if HAVE_TZSET is defined.
3421 (scm_tzset): don't define if HAVE_TZSET not defined. Change the
3422 doc string to indicate that this procedure isn't likely to do
3424 (scm_localtime, scm_strftime, scm_mktime): call tzset if
3425 LOCALTIME_CACHE is defined.
3427 2000-01-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3429 * posix.c (scm_sync): Return SCM_UNSPECIFIED.
3431 2000-01-09 Gary Houston <ghouston@arglist.com>
3433 * eval.c: define scm_unbound_variable_key ('unbound-variable).
3434 scm_lookupcar1: throw an error with key 'unbound-variable instead
3435 of 'misc-error when an unbound variable is encountered.
3437 * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
3438 scm_symlink, scm_readlink, scm_lstat),
3439 posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
3440 scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
3442 simpos.c (scm_system),
3443 stime.c (scm_times, scm_strptime):
3444 move the HAVE_XXX feature tests out of the procedure bodies.
3445 don't use SCM_SYSMISSING.
3446 scm_validate.h (SCM_SYSMISSING): removed.
3447 error.h, error.c (scm_sysmissing): comment that this is deprecated.
3448 see ChangeLog entry for 1999-12-28.
3450 Sat Jan 8 19:52:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3452 * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
3454 Sat Jan 8 17:06:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3456 * backtrace.c: Fix spelling typo in a comment.
3458 * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
3459 text. Reformatted some of the expansions.
3461 Fri Jan 7 15:50:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3463 * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
3464 report the position of the argument.
3466 * error.h, error.c (scm_out_of_range_pos): Added this function to
3467 take extra "pos" argument, the position number of the errant
3470 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
3472 * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
3473 and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
3474 prefers that and I'm reasonably indifferent.
3476 Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
3478 * snarf.h: Factor out differences between C++ and non-C++ into
3479 SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
3480 definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
3481 Mikael's macros, below, but changed names and SCM_SNARFING no
3482 longer expands to include %%% -- that must appear in the argument
3483 so that the token appears at the call-site as a reminder).
3485 2000-01-07 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3487 * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
3488 snarf macro definitions.
3490 2000-01-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3492 * chars.c (scm_integer_to_char): Use Greg's nice
3493 SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
3496 Thu Jan 6 11:48:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3498 * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
3500 Thu Jan 6 11:22:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3502 * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
3503 instead of GUILE_PROC.
3505 Thu Jan 6 11:21:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3507 * alist.c: Do not report mismatch errors on some uses of `tmp' (do
3508 this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
3511 Thu Jan 6 09:54:33 2000 Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
3513 * scm_validate.h: Remove some redundant NIMP tests.
3515 * alist.c: minimize scope of the tmp variables, and initialize
3516 them when declared. The strange SCM_NIMP tests are replaced by
3517 SCM_CONSP tests that more closely reflect the intended semantics.
3518 However, we don't get a performance penalty here, because the
3519 SCM_CONSP test was performed by the ALISTCELL test anyway. * The
3520 extremely ugly use of ASRTGO macros was removed: The calls to
3521 ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
3522 label parameter that only exists when SCM_RECKLESS is not defined.
3523 This works, because ASRTGO itself is defined in a way that it only
3524 makes use of the label parameter if SCM_RECKLESS is not defined
3525 (shudder!). Does guile make at all use of the possibility to
3526 define SCM_RECKLESS? * Codesize is likely to be reduced, since
3527 instead of two calls to SCM_ASSERT performed by the ALISTCELL test
3528 we now only get one test.
3530 * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
3531 SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
3532 some variables in `list?'. Fix `reverse' and `reverse!'
3533 primitives to handle improper lists better.
3535 Wed Jan 5 11:24:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3537 * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
3538 macros and SCM_DEFINE macros to match GNU coding standards.
3540 Wed Jan 5 11:04:24 2000 Greg J. Badros <gjb@cs.washington.edu>
3542 * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
3544 Wed Jan 5 10:59:06 2000 Greg J. Badros <gjb@cs.washington.edu>
3546 * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
3547 better consistency with the names of other SCM_VALIDATE_ macros
3548 and better conformance to guile naming policy.
3550 Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
3552 * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
3553 SCM_VALIDATE instead of 1 to avoid a check on the argument (since
3554 it's not the actual name of the formal).
3556 * guile-snarf.awk.in: Do argument/number mismatch checking and
3557 print warnings in an Emacs compile-mode parseable format.
3559 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
3560 SCM_OUTOFRANGE as 3rd argument.
3562 * random.c: Fix argument/number mismatch (that I introduced :-( ).
3564 * __scm.h: Do not #define SCM_ARG* when snarfing;
3565 lets us distinguish between 1 and SCM_ARG1 when snarfing as only
3566 the former (using the number) requires the argument to match the
3567 formal in the current argument snarfing check.
3569 * snarf.h: Give new definition of SCM_ASSERT when in
3570 snarfing mode to output a lexically-identifiable sequence that the
3571 guile-snarf.awk script uses to verify argument/position matching.
3573 * ramap.c: Remove extraneous #undef FUNC_NAME.
3575 Wed Jan 5 08:36:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3577 * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
3578 current version of the same functionality; it writes the .x output
3579 to stdout instead of directly into the file.
3581 Wed Jan 5 08:15:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3583 * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
3584 posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
3585 redundant with the safer macros. Patch from Dirk Hermann applied
3586 by hand. Thanks Dirk!
3588 * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
3591 * ramap.c: whitespace change.
3593 Tue Jan 4 14:21:35 2000 Greg J. Badros <gjb@cs.washington.edu>
3595 * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
3596 removals from Dirk Hermann.
3598 * alist.c: Rename formals to match the parameter names in the
3599 documentation, updates to documentation. Thanks Dirk Hermann!
3601 2000-01-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3603 * eval.c (SCM_CEVAL): Reverse order of
3604 scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
3605 (Thanks to Brad Knotwell.)
3607 Mon Jan 3 08:30:02 2000 Greg Harvey <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
3609 * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
3612 * pairs.h: Added a comment about the need for the SCM_SETCAR in
3615 Mon Jan 3 08:25:19 2000 Greg J. Badros <gjb@cs.washington.edu>
3617 * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
3618 SCM_NIMP tests that were redundant are now eliminated. Patches
3619 from Dirk Hermann applied by hand.
