1 2000-08-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
3 * Makefile.am: Added all necessary environments.* files.
5 * init.c: Include environments.h.
7 (scm_boot_guile_1): Initialize the environments.
9 * environments.[ch]: Added. Most of the credit for these files
10 goes to Jost Boekemeier.
12 2000-08-25 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
14 * procprop.c: #include "libguile/smob.h"; handle applicable smobs.
16 2000-08-24 Keisuke Nishida <kxn30@po.cwru.edu>
18 * smob.h (scm_smob_descriptor): Added `apply' and `gsubr_type'.
19 * smob.c (scm_make_smob_type): Initialize `apply' and `gsubr_type'.
20 (scm_set_smob_apply): New function.

24 * procs.c (scm_procedure_p): Check applicable smobs.
26 2000-08-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
28 * Makefile.am (BUILT_SOURCES): Experimentally added scmconfig.h
29 also here. (This is supposed to make sure that scmconfig.h is
30 built before all sources in order to prevent that everything has
31 to be rebuilt again. Hope it works---I'm just guessing. :)
33 * fluids.c (scm_fluid_set_x): Return SCM_UNSPECIFIED.
35 2000-08-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
37 * gc.c (scm_gc_mark): Don't use GUILE_DEBUG flag to compile in
38 extra tests. (GUILE_DEBUG is only supposed to make extra
39 debugging functions available.)
41 2000-08-21 Michael Livshin <mlivshin@bigfoot.com>
43 * gc.h (SCM_GC_CARD_N_CELLS): change to be a nice non-confusing
46 2000-08-19 Michael Livshin <mlivshin@bigfoot.com>
48 * gc.c (scm_gc_sweep): added a `continue' statement that have
49 fallen through the cracks in the merge. thanks to Shuji Narazaki!
51 * gc.h: removed some stuff that broke compilation for people and
52 wasn't actually needed anyway.
54 2000-08-18 Neil Jerram <neil@ossau.uklinux.net>
56 * filesys.c (scm_fcntl): Docstring fix - missing newlines inserted.
58 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_sethost,

71 2000-08-18 Neil Jerram <neil@ossau.uklinux.net>
73 * boolean.c (scm_not, scm_boolean_p): Docstring fixes - add
74 texinfo markup and remove trailing newlines.
76 2000-08-17 Michael Livshin <mlivshin@bigfoot.com>
78 this changes the Guile GC to use cards (aka "chunklets").
79 (most of the ideas and some of the code are by Greg Harvey, though
80 the code is probably unrecognizable now. the original chunklet
81 proposal, way back, is by Dale Jordan).
83 * tags.h: (SCM_GCTYPE16, SCM_GCCDR, SCM_GC[8]MARKP,
84 SCM_SETGC[8]MARK, SCM_CLRGC[8]MARK): moved from here into gc.h.
85 some (most) of these are probably going to be deprecated.
87 * gc.h (SCM_MARKEDP): simplified, there are no different mark bit
89 (SCM_GC_CARD_*, SCM_C_BVEC_*): lots of new macros to deal with
90 cards and bvecs (bit-vectors).
92 * gc.c: (scm_default_init_heap_size_*): defined to take cards into
93 account, but keeping more or less the same values as previously.
94 added some simple helper macros.
95 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK): defined to take cards
97 (BVEC_*, scm_mark_space_t, current_mark_space, mark_space_ptr,
98 current_mark_space_offset, mark_space_head, get_bvec,
99 clear_mark_space): new functions and supporting variables, types
100 and macros that implement mark space management.
101 (scm_igc): clear the mark space (all of it) before beginning the
103 (scm_gc_mark): changed the tests for rogue cells, much simplified
104 throughout (no different mark bit locations to worry about now).
105 (scm_mark_locations): don't consider card header cells.
107 (scm_gc_sweep): simplified.
108 (init_heap_seg): changed to take cards into account.
110 2000-08-16 Michael Livshin <mlivshin@bigfoot.com>
112 * stime.c (scm_c_get_internal_run_time): new function, same as
113 scm_get_internal_run_time but returns a long. it's used by the GC
114 for timekeeping, since with scm_get_internal_run_time there is a
115 (extremely theoretical) possibility of consing.
116 (scm_get_internal_run_time): redefined in terms of
117 scm_c_get_internal_run_time.
119 * stime.h: added prototype for scm_c_get_internal_run_time.
121 * gc.c (scm_gc_stats): add more obscure stats, such as: mark time,
122 sweep time, total marked cells, total swept cells, and number of
123 times GC was invoked.
124 (gc_start_stats): renamed from scm_gc_start, made static, taught
125 to init the new stats.
126 (gc_end_stats): renamed from scm_gc_end, made static, taught to
127 calculate the new stats.
128 (scm_igc): don't call gc_start_stats unless we are sure that we
129 are indeed going to collect. also, added some timekeeping between
130 the mark and sweep phases.
131 (scm_gc_sweep): count number of cells we sweep as we go.
133 * gc.h: removed prototypes for scm_gc_{start,end}.
135 2000-08-13 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
137 * alist.c (scm_assq, scm_assv, scm_assoc): Report argument type
138 error for the alist rather than the sublist where the type
139 mismatch is discovered.
141 2000-08-13 Neil Jerram <neil@ossau.uklinux.net>
143 * root.c (s_scm_call_with_dynamic_root): Docstring fix - rogue

166 * list.c (scm_list_tail): Add @deffnx line to docstring for
169 * keywords.c: Docstring improvements in conjunction with new
170 reference manual doc on keywords.
172 * error.c (scm_error_scm): Fix texinfo syntax error in
173 docstring. (@code(~S) should be @code{~S}.)
175 * dynl.c: Remove surplus newlines from end of docstrings.
177 2000-08-11 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
179 * eval.c (scm_eval): Backward incompatible change: Now takes an
180 environment specifier as second arg. `eval' hereby becomes R5RS
182 (scm_i_eval_x, scm_i_eval): New functions (replace
184 (scm_eval2, scm_eval_3): Deprecated.
185 (scm_top_level_lookup_closure_var): Deprecated.
187 * eval.h: #include "struct.h".
189 * evalext.c (scm_definedp): Have to work before module system is
192 * modules.h (SCM_MODULEP, SCM_VALIDATE_MODULE,

205 #include "modules.h".
207 * strports.c (scm_eval_string): Evaluate in
208 scm_interaction_environment ().
210 * script.c (scm_shell): Pass scm_the_root_module () as second arg
213 * load.c (load): Use `scm_selected_module' to compute second arg
214 to new scm_i_eval_x; Don't call it if module system hasn't booted.
215 (scm_read_and_eval_x): Deprecated.
216 #include "modules.h".
218 * debug.c (scm_local_eval): Use scm_i_eval and scm_i_eval_x.
219 (scm_start_stack): Use scm_i_eval.
221 * strports.c: #include "modules.h".
223 * print.c (scm_simple_format): Be case-insensitive for ~A and ~S
226 2000-08-09 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
228 The following changes are intended to ensure that struct instances
229 are freed before their vtables. It's optimized for the most
230 common case, which is freeing of struct instances.
232 * gc.c (scm_gc_mark, scm_gc_sweep): Remove vcell = 1 magic.
233 (scm_structs_to_free): New variable.
234 (scm_gc_sweep): Hook up structs to free on the scm_structs_to_free
237 * struct.h (SCM_STRUCT_GC_CHAIN, SCM_SET_STRUCT_GC_CHAIN): New
239 (scm_structs_to_free, scm_struct_prehistory): Declare.
241 * struct.c (scm_make_struct, scm_make_vtable_vtable): Structs
242 handles are now double cells; Initialize SCM_STRUCT_GC_CHAIN to
244 (scm_struct_gc_init, scm_free_structs): New GC C hooks.
245 (scm_struct_prehistory): Install them.
247 * init.c (scm_boot_guile_1): Call scm_struct_prehistory.
249 2000-08-06 Marius Vollmer <mvo@zagadka.ping.de>
251 * read.c (scm_flush_ws): Include filename in error message when it
254 2000-08-05 Marius Vollmer <mvo@zagadka.ping.de>
256 * iselect.c: Include <unistd.h>. Thanks to Bertrand Petit!
258 2000-08-02 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
260 * struct.c (scm_make_struct_layout, scm_make_struct,
261 scm_make_vtable_vtable): Updated documentation.
263 * print.c (scm_simple_format): Bugfix: Coerce port before using
266 2000-07-31 Gary Houston <ghouston@arglist.com>
268 * net_db.c: declare h_errno only if HAVE_H_ERRNO is not defined
269 (thanks to Richard Kim for the bug report).
271 2000-07-30 Marius Vollmer <mvo@zagadka.ping.de>
273 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
274 scm_assoc_remove_x): Use scm_delq1_x instead of scm_delq_x, since
275 using the latter is pointless.
277 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
279 * gc.c (scm_gc_sweep): Renamed local variable from 'free' to
280 'free_struct_data' to avoid confusion with stdlib's 'free'.
282 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
284 * vectors.c (scm_make_vector): Fix the initialization order of
285 the vector such that the type cell is initialized last.
287 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
289 * struct.[ch] (scm_struct_init): Made static. Fixed not to rely
290 on the struct cell to be fully initialized.
292 * struct.c (scm_make_struct, scm_make_vtable_vtable): Fix the
293 initialization order of the struct such that the type cell is
296 2000-07-25 Marius Vollmer <mvo@zagadka.ping.de>
298 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
299 scm_assoc_remove_x): Remove only the first cell with a matching
302 2000-07-24 Marius Vollmer <mvo@zagadka.ping.de>
304 * stime.c (scm_strftime): Recognize a return value of zero from
305 strftime as buffer overflow and take care to detect a valid zero
306 length result regardless. Thanks to David Barts!
308 2000-07-23 Marius Vollmer <mvo@zagadka.ping.de>
310 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
311 scm_assoc_remove_x): Remove all cells whose key is eq, eqv, or
312 equal (respectively) to the argument key, not all cells that are
313 eq, eqv, or equal to the first cell with the argument key. Thanks
316 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
318 * gc.h (SCM_FREE_CELL_CDR, SCM_SET_FREE_CELL_CDR), hooks.c
319 (make_hook), modules.c (OBARRAY, USES, BINDER): Pack and unpack
320 SCM values appropriately.
322 * modules.c (scm_standard_eval_closure): Don't pass an inum to
323 scm_makcclo, but rather a long value.
325 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
327 read.c (scm_lreadrecparen), srcprop.c (scm_set_source_property_x):
328 SCM_SETCDR and SCM_WHASHSET macros don't deliver a return value.
329 Thanks to Han-Wen Nienhuys for the bug report.
331 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
333 * root.[ch] (scm_call_catching_errors): Deprecated.
335 * root.c (scm_init_root): Initialize the root smob type using the
336 standard initialization functions.
338 2000-07-17 Marius Vollmer <mvo@zagadka.ping.de>
340 * eval.c (unmemocopy): Don't rely on V being a list of at least
341 one element. Thanks to Bill Schottstaedt!
343 2000-07-15 Michael Livshin <mlivshin@bigfoot.com>
345 * gc.c (scm_done_free): new.
346 expanded comments about scm_done_malloc.
348 * gc.h: added prototype for scm_done_free
350 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
352 * gc.h (scm_take_stdin): Removed.
354 * gc.h (SCM_VALIDATE_CELL): Delegate cell checks to function
355 scm_assert_cell_valid to allow extensions to the checking
356 functionality without need to recompile everything.
358 * gc.[ch] (scm_assert_cell_valid, scm_set_debug_cell_accesses_x):
359 Added as conditionally compiled functions for the case that
360 SCM_DEBUG_CELL_ACCESSES is enabled.
362 * gc.c (debug_cells_p): Added to indicate whether compile-time
363 included cell access debugging is run-time enabled.
365 * gc.[ch] (scm_gc_running_p): Added to indicate that scm_igc is
366 being executed. Intended to be used instead of scm_gc_heap_lock
369 * error.c (scm_error), gdbint.c (SCM_GC_P): Use scm_gc_running_p
370 instead of scm_gc_heap_lock.
372 * gc.c (scm_igc): Set scm_gc_running_p to true while running.
374 * gc.c (scm_mark_locations): Don't mark free cells.
376 * weaks.c (scm_scan_weak_vectors): Use SCM_FREE_CELL_P instead of
379 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
381 * gc.c (scm_mark_locations): Minimized some variable scopes and
382 simplified the code a bit.
384 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
386 * gc.h (SCM_SET_FREE_CELL_TYPE, SCM_SET_FREE_CELL_CDR,
387 SCM_FREE_CELL_P, SCM_FREE_CELL_CDR): Added since free cells
388 should not be accessed via SCM_C[AD]R. Further, using dedicated
389 macros to access free cells allows all other cell accessing macros
390 to treat acesses to free cells as errors, thus enabling better
391 error checks for cell accesses. SCM_FREE_CELL_P is supposed to
392 replace SCM_FREEP some time.
394 * gc.h (SCM_NEWCELL, SCM_NEWCELL2), gc.c (map_free_list,
395 free_list_length, scm_check_freelist, scm_debug_newcell,
396 scm_debug_newcell2, freelist_length, scm_gc_for_newcell,
397 scm_gc_mark, scm_gc_sweep, init_heap_seg): Only use the dedicated
398 cell accessors when accessing free cells.
400 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
402 * gc.h (SCM_CELL_WORD, SCM_CELL_OBJECT): Treat the referenced
403 object as const in order to make the compiler warn about code like
404 SCM_CELL_WORD (x, n) = y. Instead, SCM_SET_CELL_WORD (x, n, y)
407 (SCM_CELL_WORD_LOC, SCM_CARLOC, SCM_CDRLOC): Return the address
408 as an address to a non-const object, since these macros are used
409 to allow direct write access to objects.
411 2000-07-07 Dirk Herrmann <D.Herrmann@tu-bs.de>
413 * hashtab.c (scm_hash_fn_create_handle_x): Signal an error if the
414 given hash table has no slots.
416 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
418 * gc.c (policy_on_error): Added in order to allow alloc_some_heap
419 to react to malloc failures in a context dependent way.
421 (scm_check_freelist): No need to flush streams before abort().
423 (scm_gc_for_newcell): Try to allocate new memory in three phases:
424 grow heap if preferred, if still no memory available collect
425 garbage, if still no memory available grow heap.
427 (heap_segment_table_size): Added to always reflect the actual
428 size of the heap segment table, because scm_n_heap_segs may differ
429 from the heap segment table size.
431 (alloc_some_heap): In case of malloc failure, react according to
432 the new policy_on_error parameter (either return to caller or
433 abort immediately). Further, keep heap_segment_table_size up to
436 (scm_init_storage): Initialize heap_segment_table_size.
438 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
440 * gh.h: Don't include <stdio.h>. Thanks to Han-Wen Nienhuys for
443 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
445 * __scm.h (SCM_OUTOFRANGE, SCM_NALLOC, SCM_HUP_SIGNAL,
446 SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL,
447 SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL, SCM_SIG_ORD,
448 SCM_ORD_SIG, SCM_NUM_SIGS): Re-introduce these as deprecated
451 * error.c (scm_wta): Re-introduce dispatching for SCM_OUTOFRANGE
452 and SCM_NALLOC, but as a deprecated feature.
454 2000-06-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
456 * debug.c: Added #include fluids.h.
458 * numbers.c (scm_gr_p, scm_leq_p, scm_geq_p): Turned into
459 primitive generics. (Thanks to Nicolas Neuss.)
461 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
463 * gc.c (alloc_some_heap): Use scm_memory_error to indicate a
464 failed attempt to get additional memory from the system.
466 (scm_gc_for_newcell): Changed the control structure to make the
467 behaviour explicit for the case that gc is not able to free any
470 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
472 * __scm.h (SCM_OUTOFRANGE): Removed.
474 * error.c (scm_wta): Removed sick dispatch code for range
475 errors. (More sick dispatches still to be removed.)
477 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
478 scm_hash_fn_remove_x): Eliminate redundant test for if unsigned
479 value is non-negative. Use scm_out_of_range to signal range
482 * hooks.c (make_hook), unif.c (scm_aind): Use scm_out_of_range to
485 * list.c (scm_list_ref, scm_list_set_x, scm_list_cdr_set_x): Fix
486 error reporting (now uses original input parameter to report wrong
487 type argument errors). Use SCM_OUT_OF_RANGE to report range
488 errors and SCM_WRONG_TYPE_ARG to report type errors.
490 * strings.c (scm_substring): Make range checks for negative
491 values explicit (former behaviour relied on an implicit
492 conversion from signed to unsigned). Don't use SCM_ASSERT for
495 * unif.c (scm_aind, scm_transpose_array, scm_bit_set_star_x,
496 scm_bit_count_star): Use scm_out_of_range to signal range
499 * unif.c (scm_transpose_array, scm_bit_position), vectors.c
500 (scm_vector_ref, scm_vector_set_x, scm_vector_move_left_x,
501 scm_vector_move_right_x): Use SCM_ASSERT_RANGE to check ranges.
503 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
505 * validate.h (SCM_VALIDATE_INUM_MIN_COPY,
506 SCM_VALIDATE_INUM_MIN_DEF_COPY, SCM_VALIDATE_INUM_RANGE_COPY):
507 Perform all range checks based on the input value. The former way
508 of using the value that is assigned to the target variable fails
509 if the assignment to the target variable itself can change the
510 value because of type conversion.
512 (SCM_ASSERT_RANGE): Use scm_out_of_range to signal range errors.
514 2000-06-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
516 * gc.c (scm_gc_for_newcell): Behave gracefully also if scm_igc
517 doesn't yield any new cells. In theory this could happen if all
518 cells allocated with NEWCELL are either in use or conservatively
519 marked and all cluster spine cells are conservatively marked.
522 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
524 * __scm.h (SCM_NALLOC): Removed.
526 * error.c (scm_wta): Removed sick dispatch code for memory
527 errors. (More sick dispatches still to be removed.)
529 * numbers.c (scm_mkbig, scm_adjbig), ports.c (scm_make_port_type),
530 random.c (scm_i_copy_rstate, scm_c_make_rstate), smob.c
531 (scm_make_smob_type), srcprop.c (scm_make_srcprops), vectors.c
532 (scm_vector_set_length_x): Now using scm_memory_error to signal
535 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
537 * __scm.h: Removed some commented code and fixed some comments.
539 (SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL,
540 SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL,
541 SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS): Removed.
543 * async.c: Removed some commented code.
545 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
547 * gc.c (scm_gc_mark, scm_gc_sweep, scm_must_malloc,
548 scm_must_realloc, scm_must_free, alloc_some_heap): Use the
549 appropriate error signalling function.
551 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
553 * root.h (scm_first_type): Removed.
555 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
557 * gc.c (MIN_GC_YIELD): Removed.
559 2000-06-28 Michael Livshin <mlivshin@bigfoot.com>
561 * gc.c (scm_gc_for_newcell): don't try to do GC if it's blocked,
564 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
566 * async.c (scm_gc_async, scm_gc_vcell, scm_sys_gc_async_thunk):
569 (scm_init_async): Moved initialization for scm_gc_async and
570 scm_gc_vcell to gc.c. Moved initialization of scm_asyncs here
573 * async.h (scm_gc_async): Not globally visible any more.
575 * gc.c (scm_gc_stats): Made callable even from within regions
578 (scm_gc_end): Eliminate the hardcoding of the marking of the
579 scm_gc_async from the gc core.
581 (scm_init_storage): Don't initialize the scm_asyncs list here.
582 This is now done in asyncs.c.
584 (scm_gc_vcell): Moved here from async.c.
586 (gc_async): Renamed from scm_gc_async, moved here from async.c
589 (gc_async_thunk): Renamed from scm_sys_gc_async_thunk and moved
592 (mark_gc_async): New hook function for scm_after_gc_c_hook.
594 (scm_init_gc): Added initialization of scm_gc_vcell and
595 gc_async. Further, add mark_gc_async to scm_after_gc_c_hook.
597 * init.c (scm_boot_guile_1): scm_init_gc requires asyncs to be
600 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
602 * gc.c (scm_igc): Removed commented code that once was intended
603 to unprotect struct types with no instances.
605 * root.h (scm_type_obj_list): Removed.
607 2000-06-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
609 * async.c (scm_init_async): Switch to standard way of smob
612 2000-06-21 Michael Livshin <mlivshin@bigfoot.com>
614 * guile-doc-snarf.in: use cut instead of sed, that's much much
615 faster. also, don't call basename more than needed. and, to gain
616 a couple of microseconds more, don't call cat needlessly. (thanks
619 2000-06-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
621 * guile-snarf.awk.in, guile-snarf.in, snarf.h: Rename SCM__I to
622 SCM_SNARF_INIT_START, SCM__D to SCM_SNARF_DOC_START, SCM__S to
623 SCM_SNARF_DOCSTRING_START and SCM__E to SCM_SNARF_DOCSTRING_END.
625 2000-06-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
627 * eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
628 #include "libguile/fluids.h".
630 * eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
631 SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
633 * root.h (scm_top_level_lookup_closure_var,
634 scm_system_transformer): Removed. (It's no sense in having the
635 *variable* be a "fluid".)
637 * root.c (mark_root): Removed marking of
638 s->top_level_lookup_closure_var and s->system_transformer.
640 * modules.c (scm_selected_module): the_module is now a fluid.
642 2000-06-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
644 * gc.h, tags.h: Be kind to compilers which must see hash signs in
645 column 0. (Thanks to Ian Grant.)
647 * numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
648 the long_long type. (Thanks to Bernard Urban.)
650 2000-06-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
652 * gc.c, gc.h (scm_default_init_heap_size_1,
653 scm_default_min_yield_1, scm_default_init_heap_size_2,
654 scm_default_min_yield_2, scm_default_max_segment_size): New global
655 variables. Can be customized by the application before booting
656 Guile. (We might want to be able to control these parameters
657 dynamically through the "options interface" in the future, but
658 note that that is additional functionality. Here we're giving
659 default values which the environment variables can override.)
661 * list.c (scm_cons_star): Updated comment.
663 * smob.h: Changed comments for scm_make_smob_type and
664 scm_make_smob_type_mfpe, warning that the latter might be
665 deprecated in a future release.
667 2000-06-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
669 * list.[ch] (scm_cons_star/cons*): Renamed from
672 * list.[ch] (scm_list_star/list*): Provided as a deprecated alias
673 for scm_cons_star/cons*.
675 * gc.c (scm_protect_object): Updated comment.
677 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX): Removed.
679 * tags.h (SCM_UNPACK_CAR, SCM_NDOUBLE_CELLP): Removed.
681 2000-06-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
683 * init.c, init.h (scm_initialized_p): Renamed from `initialized'
686 * gdbint.c (gdb_print): Print warning instead of calling scm_write
687 if Guile isn't yet initialized.
689 * print.c (scm_current_pstate, scm_make_print_state): Simplified
690 tests, using the assumption that Guile has been initialized.
692 Sun Jun 18 14:45:21 2000 Greg J. Badros <gjb@cs.washington.edu>
694 * print.c (s_scm_current_pstate): Do not segfault when the
695 print_state_pool is unitialized in `current-pstate', and better
696 verify its state before altering it in scm_make_print_state().
698 2000-06-18 Michael Livshin <mlivshin@bigfoot.com>
700 * scmsigs.c (s_scm_sigaction): guard the SIGIOT case with an
701 #ifdef -- it's missing on at least one platform. (thanks to
704 2000-06-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
706 * list.c (list*): Added documentation from common-list.scm.
708 2000-06-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
710 * gc.c (scm_unprotect_object): The reference count is guaranteed
711 to be a positive number.
713 2000-06-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
715 * eval.c: Updated comment above scm_map.
717 2000-06-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
719 * gc.c (scm_protect_object): Avoid looking up the object handle
721 (scm_unprotect_object): Abort if scm_unprotect_object is called on
722 an unprotected object.
724 2000-06-14 Michael Livshin <mlivshin@bigfoot.com>
726 * gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
729 2000-06-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
731 * socket.c (scm_getsockopt): Changed type for `optlen' from int to
733 (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
734 Ditto for `tmp_size'.
735 (scm_addr_buffer_size): Changed type from int to size_t.
737 * random.c: #include <string.h>. (Needed by memcpy.)
739 * guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
740 indicating stdin, instead of "" and don't reset ARGC. This is a
741 workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
742 it is correct, and perhaps even better.
744 2000-06-14 Gary Houston <ghouston@arglist.com>
746 * scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not
747 defined, add SA_RESTART to the sigaction flags correctly
748 (thanks to Dale P. Smith).
750 2000-06-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
752 * strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
754 * net_db.c (scm_resolv_error): Only use macro NETDB_INTERNAL if
755 defined. It isn't on sgi irix 5.3. (Thanks to Bill Schottstaedt.)
757 * Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
759 2000-06-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
761 * fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
762 since read and write buffers are allocated by `malloc'.
764 * Makefile.am: Removed old test code.
766 * gh_test_c.c, gh_test_repl.c: Removed.
768 2000-06-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
770 * iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2
773 * inet_aton.c (inet_aton): Cast init value for `cp'.
775 * ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
778 * symbols.c (scm_intern_obarray_soft,
779 scm_sysintern0_no_module_lookup): Cast `name' to unsigned char ptr
780 in calls to scm_strhash.
782 * strports.c (st_resize_port): Substituted SCM_UCHARS for
784 (st_write): Cast argument to strncpy to char ptr.
785 (scm_mkstrport): Substituted SCM_ROUCHARS for SCM_ROCHARS.
786 (scm_strport_to_string): Cast argument to scm_makfromstr to char
789 * ports.c (scm_ungetc): Cast value to unsigned char ptr before
790 storing in putback_buf.
791 (scm_unread_string): Substituted SCM_ROCHARS for SCM_ROUCHARS.
793 * ioext.c (s_scm_read_line): Cast result of call to
794 scm_do_read_line to unsigned char ptr.
796 * gdbint.c (SEND_STRING): Cast argument to char pointer.
798 * fports.c (fport_flush): Declare `ptr' as unsigned char (was
801 * Makefile.am (DOT_DOC_FILES): List doc-files explicitly. (We
802 shouldn't use Make rules which aren't supported by most Make
804 (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h". (We don't
805 want these dependencies recorded, since they would get bogus
806 relative paths; libguile.h is only used in gh.h and guile.c.)
807 (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
808 (guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
809 (modinclude_HEADERS): Removed kw.h.
811 * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
812 (The preprocessor might insert spaces before the identifier.)
814 * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
815 Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
817 * smob.h (scm_smobfuns): Removed deprecated type.
819 * smob.c, smob.h (scm_newsmob): Removed deprecated function.
820 (Replaced by `scm_make_smob_type'.)
822 * keywords.c (scm_tc16_kw): Removed deprecated type.
823 (Replaced by scm_tc16_keyword.)
825 * kw.h: Removed deprecated header file.
827 * evalext.c (serial-map): Removed deprected alias for scm_map.
828 (Has been replaced by `map-in-order'.)
830 * ramap.c (serial-array-copy!, serial-array-map!): Removed
831 depracted aliases. (Replaced by `array-copy-in-order!' and
832 `array-map-in-order'.)
834 2000-06-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
836 * gc.h (SCM_VALIDATE_CELL): Rewritten.
837 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
838 SCM_SET_CELL_OBJECT): Use new version of SCM_VALIDATE_CELL.
839 (Thanks to Han-Wen Nienhuys.)
841 2000-06-10 Michael Livshin <mlivshin@bigfoot.com>
843 * guile-doc-snarf.in: don't pipe the CPP output right into sed --
844 write it to the temp file first and check the CPP return code.
845 (I introduced this bug earlier, and this probably caused people
846 with non-GNU C preprocessors to get empty *.x files and not to
847 have the build fail right away...).
849 * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
850 -- at least my libc5-based Linux system doesn't define SIGSYS.
852 2000-06-08 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
854 * snarf.h, guile-snarf.awk.in, guile-snarf.in: Replaced snarf
855 markers with identifiers (SCM__I, SCM__D, SCM__S, SCM__E).
856 (Thanks to Bernard Urban.)
858 2000-06-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
860 * modules.c (scm_system_module_env_p): Fixed detection of system
863 2000-06-06 Marius Vollmer <mvo@zagadka.ping.de>
865 * scmsigs.c (scm_sigaction): Silently ignore setting handlers for
866 `program error signals' because they can't currently be handled by
869 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
871 * procs.h (SCM_SET_SUBRF): Added.
873 * procs.c (scm_make_subr_opt): Don't assign to SCM_SUBRF, use
874 SCM_SET_SUBRF instead. Thanks to Bernard Urban for the bug
877 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
879 * gc.h (SCM_CARLOC, SCM_CDRLOC): Don't take the address of a SCM
882 * sort.c (scm_sorted_p, scm_merge, scm_merge_list_x,
883 scm_merge_list_step): Don't take the address of SCM_CAR. Use
884 SCM_CARLOC instead. Thanks to Bernard Urban for the bug report.
886 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
888 * boolean.h (SCM_TRUE_P): Removed, as people might use it as a
889 replacement for !SCM_FALSEP.
891 * backtrace.c (display_error_body), boolean.h (SCM_BOOLP), gc.c
892 (scm_unhash_name), gh_data.c (gh_module_lookup), load.c
893 (scm_primitive_load), print.c (scm_simple_format), procs.c
894 (scm_procedure_documentation), procs.h (SCM_TOP_LEVEL), ramap.c
895 (scm_array_fill_int), scmsigs.c (scm_sigaction), stacks.c
896 (narrow_stack, scm_make_stack, scm_stack_id), symbols.c
897 (scm_string_to_obarray_symbol), throw.c (scm_catch,
898 scm_lazy_catch, scm_ithrow), unif.c (scm_make_uve, scm_array_p,
899 scm_array_set_x, scm_bit_set_star_x, scm_bit_count_star),
900 validate.h (SCM_VALIDATE_BOOL_COPY, SCM_VALIDATE_PROC): Replace
901 uses of SCM_TRUE_P (x) with SCM_EQ_P (x, SCM_BOOL_T).
903 2000-06-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
905 * eval.c (scm_badformalsp): New static function.
906 (SCM_CEVAL): Check arguments for procedure-with-setter closures.
907 (Thanks to Keisuke Nishida.)
909 The major reason for Guile's slow loading speed has been the fact
910 that a chain of Scheme level procedures has been evaluated for
911 every top-level symbol lookup during the first pass through the
914 The following is a kludge which I suggested four years ago, and
915 which I've repeatedly suggested since. Personally, I've never
916 been bothered by Guile's slow loading speed, so I thought I would
917 let someone else do it...
919 But since the new environments will be included first in
920 Guile-1.5, I thought it would make people happy to get the kludge
923 * modules.c: Added #include "libguile/vectors.h";
924 Added #include "libguile/hashtab.h";
925 Added #include "libguile/struct.h";
926 Added #include "libguile/variable.h";
927 Capture Scheme level `module-make-local-var!' to be used in the
928 standard eval closure.
929 (scm_standard_eval_closure): New primitive.
931 * modules.h (scm_standard_eval_closure): Declare.
933 * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
934 instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
936 * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
937 standard eval closures.
939 * variable.c: Code layout fixes.
941 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
943 * Makefile.am: Added LIBS line to libpath which accidentally
944 disappeared in the change of 2000-06-01.
945 (Thanks to Dale P. Smith.)
947 2000-06-03 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
949 * scmsigs.c (scm_segfault): Removed. (Was probably added by
950 mistake since it is not mentioned in ChangeLog.)
952 * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
953 avoid compiler warnings in gcc. (Does this work for other
956 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
958 * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
960 (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
961 SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1. It's not correct to take
962 the address of these expressions since they use SCM_VALIDATE_CELL.
963 (Thanks to Bernard Urban.)
965 * dynl.c: Changed #include <ltdl.h> --> #include
966 "libltdl/ltdl.h". (Thanks to Bill Schottstaedt.)
968 2000-06-01 Craig Brozefsky <craig@red-bean.com>
970 * Makefile.am: libguile_la_LDFLAGS gets -version-info args
971 from GUILE-VERSION definition of LIBGUILE version. Added to
972 libpath.h definitions for guileversion and libguileversion which
973 both get their values from GUILE-VERSION definition.
975 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
977 * numbers.h (SCM_BIGP): Don't use SCM_SMOB_PREDICATE in header
978 file: Code using numbers should not be required to include
981 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
983 * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
984 mit-pthreads.c, mit-pthreads.h: Deleted.
986 * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]: Drop
987 references to deleted files and fsu/mit thread support in
990 2000-05-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
992 * hooks.c (symbol_name, scm_create_hook): Restored the original
993 behaviour of scm_create_hook. Changing it was bad as Carl
994 R. Witty has pointed out.
996 * gc.c (scm_init_gc): We can still rely on scm_create_hook to
999 2000-05-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
1001 * gc.c (scm_init_gc): Protect scm_after_gc_hook, since this will
1002 soon not be done by scm_create_hook any longer.
1004 * hooks.c (make_hook, print_hook, scm_create_hook,
1005 scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
1006 SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
1007 scm_make_hook_with_name), init.c (scm_boot_guile_1): Hooks no
1008 longer have names. As an intermediate solution, the name
1009 predicate is emulated via object properties, but use of this
1010 feature is deprecated.
1012 * hooks.h (scm_free_hook): Removed, as it is never defined.
1014 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1016 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
1017 Un-deprecated since otherwise user code can't determine whether a
1018 number fits into an inum any longer. The names should be changed
1021 * numbers.c (scm_big2inum): Eliminated use of SCM_UNEGFIXABLE.
1023 * tags.h (SCM_UNPACK_CAR): Deprecated.
1025 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1027 * filesys.h (SCM_OPDIRP), fluids.h (SCM_FLUIDP, SCM_FLUID_NUM),
1028 fports.h (SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP), hooks.h
1029 (SCM_HOOK_ARITY), keywords.h (SCM_KEYWORDP, SCM_KEYWORDSYM),
1030 numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
1031 Replace SCM_UNPACK_CAR appropriately. Don't access cells via
1032 SCM_{SET}?C[AD]R unless they are known to be cons cells.
1034 * gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
1035 init_heap_seg): Remove unused struct member variable 'valid'.
1037 2000-05-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
1039 * fports.c (fport_write), ports.c (scm_markstream, scm_port_mode,
1040 scm_print_port_mode), ports.h (SCM_OPPORTP, SCM_OPINPORTP,
1041 SCM_OPOUTPORTP, SCM_INPUT_PORT_P, SCM_OUTPUT_PORT_P, SCM_OPENP),
1042 procs.h (SCM_CLOSCAR), unif.h (SCM_ARRAY_NDIM, SCM_ARRAY_CONTP),
1043 variable.h (SCM_VARIABLEP): Replace SCM_UNPACK_CAR
1046 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1048 * gc.c (free_list_length), hash.c (scm_hasher), macros.c
1049 (scm_macro_type), objects.c (scm_class_of), options.c
1050 (scm_options), print.c (scm_iprin1), strports.c (st_seek), throw.c
1051 (SCM_LAZY_CATCH_P): Replace SCM_UNPACK_CAR appropriately.
1053 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1055 * eval.c (scm_macroexp, SCM_CEVAL, scm_force), tags.h: Replace
1056 SCM_UNPACK_CAR with SCM_CELL_TYPE or SCM_CELL_WORD_0.
1058 * eval.c (scm_force): Add documentation.
1060 * eval.c (scm_force, scm_cons_source): Don't access cells via
1061 SCM_{SET}?C[AD]R unless they are known to be cons cells.
1063 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1065 * strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
1066 (SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP): Deprecated.
1068 * gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT): Removed #ifdef
1069 nosve #endif conditionally compiled code.
1071 2000-05-23 Michael Livshin <mlivshin@bigfoot.com>
1073 * gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
1075 2000-05-22 Michael Livshin <mlivshin@bigfoot.com>
1077 * guile-doc-snarf.in: put the preprocessed file through sed to
1078 trim all lines to 1024 chars. I hope it doesn't break anybody's
1079 sed. we'll see. (note: this is lossy trimming, i.e. the spill
1080 isn't wrapped around but actually chopped off. this seemed to me
1081 safe because the current snarfer doesn't understand multi-line
1082 cookies anyway. in the long term, it would be nice not to depend
1083 on AWK for anything.)
1085 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
1086 the previous change to this macros, after deciding to torture the
1089 2000-05-21 Michael Livshin <mlivshin@bigfoot.com>
1091 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
1092 the yucky, ugly and nasty conditional compilation back. sorry,
1093 but it was either that or requiring GAWK to build Guile.
1094 (lots of places): removed the code that implemented the old GC
1097 * init.c (scm_boot_guile_1): removed the code conditioned on
1098 !GUILE_NEW_GC_SCHEME.
1100 * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
1102 * gc.c (scm_protect_object, scm_unprotect_object): change the
1103 implementation to more efficient (at least in the time complexity
1104 sense). the calls should now also be thread-safe -- I suspect
1105 that people expect them to be. (thanks to Han-Wen Nienhuys)
1106 (lots of places): removed the code that implemented the old GC
1109 * hashtab.c (scm_hash_fn_create_handle_x): add missing
1110 SCM_REALLOW_INTS before return. I really wonder about the
1111 possible interactions between hashtables, threads & GC. it
1112 doesn't look healthy at all.
1114 2000-05-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1116 * unif.c (scm_bit_count): Fixed the parameter checks. Thanks to
1119 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1121 * __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_): Added as a new
1122 debug option to verify all accesses to cells actually access
1123 objects on the heap.
1125 * gc.h (SCM_VALIDATE_CELL): Added. Only performs validation if
1126 SCM_DEBUG_CELL_ACCESSES is set to 1.
1128 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
1129 SCM_SET_CELL_OBJECT): Use SCM_VALIDATE_CELL to check every cell
1132 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1134 * gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs,
1135 gh_scm2floats, gh_scm2doubles): Change !SCM_NIMP to SCM_IMP.
1137 * gc.c (scm_cellp): Fixed and simplified.
1139 * throw.c (JBJMPBUF, SETJBJMPBUF, SCM_JBDFRAME, SCM_SETJBDFRAME,
1140 make_jmpbuf, scm_init_throw): Now using double cells to represent
1141 jump buffers when using debug extensions.
1145 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1147 * gh.h gh_data.c gh_funcs.c (gh_new_procedure*, gh_chars2byvect,

1149 gh_doubles2dvect, gh_doubles2scm, gh_define, gh_lookup,
1150 gh_module_lookup): Accept const pointers as parameters.
1152 * gh.h gh_data.c (gh_int2scmb): Deprecated.
1154 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1156 * __scm.h (SCM_DEBUG_REST_ARGUMENT): Renamed from
1157 SCM_DEBUG_REST_ARGUMENTS in order to clarify that we don't test
1158 the actual arguments in the list, but rather the rest argument as
1159 a list of arguments.
1161 * validate.h (SCM_VALIDATE_REST_ARGUMENT): Added.
1163 * async.c (scm_noop), eval.c (scm_map, scm_for_each), list.c
1164 (scm_list_star, scm_append, scm_append_x), ports.c
1165 (scm_close_all_ports_except), ramap.c (scm_array_map_x,
1166 scm_array_for_each), regex-posix.c (scm_make_regexp), stacks.c
1167 (scm_make_stack), strings.c (scm_string_append), struct.c
1168 (scm_make_struct, scm_make_vtable_vtable): Validate rest arguments.
1170 * dynl.c (DYNL_GLOBAL, sysdep_dynl_link, kw_global, sym_global,
1171 scm_dynamic_link, scm_init_dynamic_linking), dynl.h
1172 (scm_dynamic_link): Removed possibility to pass flags to
1173 scm_dynamic_link, as it had no effect anyway.
1175 * filesys.c (scm_fcntl): Made single optional rest argument into
1176 a standard optional argument.
1178 * hooks.c (scm_run_hook): A list of rest arguments is never
1181 * list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
1182 strings.c (scm_string_append): Don't perform half-hearted checks
1183 to see whether the rest argument forms a proper list any more, use
1184 SCM_VALIDATE_REST_ARGUMENTS instead.
1186 * ports.c (scm_close_all_ports_except): Accept empty list of rest
1189 * posix.c (scm_convert_exec_args), print.c (scm_simple_format):
1190 Simplify verification of rest argument.
1192 * stacks.c (scm_make_stack), stacks.h (scm_make_stack), throw.c
1193 (ss_handler, handler_message): Make first mandatory rest argument
1194 of scm_make_stack into a standard mandatory argument.
1196 * unif.c (scm_transpose_array, scm_enclose_array,
1197 scm_array_in_bounds_p), unif.h (scm_transpose_array,
1198 scm_enclose_array, scm_array_in_bounds_p): Make first mandatory
1199 rest argument into a standard mandatory argument.
1201 2000-05-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
1203 * __scm.h: Added SCM_DEBUG as default debug option. (Thanks to
1204 Keisuke Nishida for the suggestion.) Added debug option
1205 SCM_DEBUG_REST_ARGUMENTS.
1207 * eval.c (scm_map, scm_for_each): Make sure all lists have the
1208 same length. Also, removed redundant parameter checks.
1210 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1212 * Makefile.am: Let 'make clean' remove *.x and *.doc files.
1214 * __scm.h: Improved explanation of giving options to make.
1216 * __scm.h (SCM_DEBUG_TYPING_STRICTNESS), tags.h
1217 (SCM_STRICT_TYPING, SCM_DEBUG_TYPING_STRICTNESS): Renamed
1218 SCM_STRICT_TYPING to SCM_DEBUG_TYPING_STRICTNESS and moved the
1219 corresponding declaration and comment to __scm.h.
1221 * _scm.h (errno), gc.h (SCM_CELLPTR, SCM_PTR_LT), numbers.c
1222 (scm_remainder, scm_modulo), numbers.h (SCM_SRS, SCM_MAKINUM,
1223 SCM_INUM): Removed conditionally compiled code for Turbo C.
1225 * gdbint.c (gdb_maybe_valid_type_p): Eliminated call to scm_tag.
1226 That check can be assumed to be redundant except for very rare
1227 conditions that actually indicate broken heap data.
1229 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1231 * numbers.c (scm_logcount, scm_integer_length): Reordered
1234 2000-05-15 Gary Houston <ghouston@arglist.com>
1236 * stime.c (scm_strftime): don't reset TZ if zone is an empty
1237 string. append a "0" to the zone for TZ.
1239 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
1241 * numbers.c (scm_logbit_p, scm_bit_extract): Reordered dispatch
1244 (scm_bit_extract): Fixed handling of bignums.
1246 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
1248 * async.c (scm_sys_gc_async_thunk), chars.h (SCM_ICHRP, SCM_ICHR,
1249 SCM_MAKICHR), continuations.h (SCM_SETJMPBUF), error.c

1253 SCM_INPORTP, SCM_OUTPORTP), ramap.c ('serial-array-copy!,
1254 'serial-array-map!), smob.c (scm_newsmob), smob.h (scm_smobfuns,
1255 scm_newsmob), tag.c (scm_tag), tag.h (scm_tag), tags.h
1256 (scm_tc16_flo, scm_tc_flo, scm_tc_dblr, scm_tc_dblc): Wrapped
1257 deprecated code between #if (SCM_DEBUG_DEPRECATED == 0) #endif.
1259 * fports.c (scm_fport_buffer_add), ports.c (scm_input_port_p,
1260 scm_output_port_p), print.c (scm_get_print_state), validate.h
1261 (SCM_VALIDATE_CHAR): Replace use of deprecated macros
1262 SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
1263 SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
1265 2000-05-14 Gary Houston <ghouston@arglist.com>
1267 * stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
1268 TZ environment variable so that the %Z format returns the zone
1269 from the input vector instead of the system default.
1271 from Keisuke Nishida:
1272 * fports.c (scm_setvbuf): minor docstring fix.
1273 * ports.h (scm_generic_fgets): obsolete prototype deleted.
1275 2000-05-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
1277 * __scm.h: Added new section for debugging options.
1279 (SCM_DEBUG_DEPRECATED): If 1, no deprecated code is included to
1280 help developers to get rid of references to deprecated code.
1282 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,
1283 SCM_FIXABLE, SCM_FLOBUFLEN): These macros are no longer provided
1284 as part of the interface and are marked as deprecated in the
1287 * numbers.c (scm_make_real, scm_make_complex): Inlined the
1288 corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
1291 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,
1292 SCM_REAL, SCM_IMAG, SCM_REALPART, scm_makdbl, SCM_SINGP,
1293 SCM_NO_BIGDIG, SCM_NUM2DBL, scm_dblproc): Deprecated.
1295 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1297 * gc.h (scm_cell, SCM_CELL_WORD, SCM_CELL_OBJECT,
1298 SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT): Scheme cells now consist
1299 of two scm_bits_t values instead of two SCM values, because it is
1300 legal for cell entries to hold values that are not scheme objects.
1302 (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
1303 Use SCM_SETC[AD]R to modify contents of pairs.
1305 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1307 * numbers.c (IS_INF, isfinite): Added FIXME comment.
1309 (scm_abs, scm_magnitude): Make these two independent of each
1310 other. scm_abs now reports an error if given a complex argument.
1312 (scm_istr2flo, scm_integer_p). Use SCM_REAL_VALUE instead of
1313 SCM_REALPART if the object is known to be real.
1315 (scm_init_numbers): No need to use SCM_NEWREAL macro for speed
1318 * numbers.h (SCM_SINGP): Set to 0 instead of SCM_BOOL_F.
1320 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1322 * eq.c (scm_eqv_p): Separate handling of real and complex
1323 values. Remove #ifdef SCM_BIGDIG #endif test.
1325 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_scm2floats,
1326 gh_scm2doubles), hash.c (scm_hasher), ramap.c (scm_array_fill_int,
1327 ramap_rp, scm_array_map_x), random.c (vector_scale,
1328 vector_sum_squares), unif.c (scm_make_uve, scm_array_p,
1329 scm_array_set_x): Use SCM_REAL_VALUE instead of SCM_REALPART if
1330 the object is known to be real. Use SCM_COMPLEXP instead of
1331 deprecated SCM_CPLXP. Use SCM_INEXACTP instead of deprecated
1334 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1336 * numbers.c: No need to include unif.h.
1338 (IS_INF): Returned to old test for now: x == x + 1 will not work
1339 for large numbers due to rounding errors.
1340 Thanks to Kalle Olavi Niemitalo.
1342 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1344 * numbers.c (scm_divbigdig): Removed outdated comment.
1346 (scm_number_to_string, scm_string_to_number, scm_number_p,
1347 scm_real_p, scm_integer_p, scm_inexact_p, scm_gr_p, scm_leq_p,
1348 scm_geq_p, scm_make_rectangular, scm_make_polar,
1349 scm_inexact_to_exact): Added comments.
1351 (add1, scm_init_numbers): Removed add1.
1353 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1355 * numbers.c (IS_INF): The new test is x == x + 1. The old test
1356 x == x/2 did not work for zero values. Thanks to Han-Wen Nienhuys
1359 (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
1360 scm_num2long, scm_num2long_long, scm_num2ulong): Reordered
1363 2000-05-09 Marius Vollmer <mvo@zagadka.ping.de>
1365 * scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
1366 SIGILL and SIGBUS signals. These signals are not continuable and
1367 must be handled for real right away.
1369 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1371 * numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,
1372 scm_real_part, scm_imag_part, scm_magnitude,
1373 scm_inexact_to_exact): Reordered dispatch sequence.
1375 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1377 * feature.c: No need to include "libguile/smob.h"
1379 (scm_loc_features, features, scm_add_feature, scm_init_feature):
1380 Removed variable 'scm_loc_features' as a pointer to the SCM value
1381 holding the features list. Using variable 'features' instead,
1382 which holds the interned pair. Thus, SCM_SETCDR can be used
1383 instead of pointer trickery.
1385 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1387 * alist.c (scm_acons): Use SCM{_SET}?_CELL_OBJECT as long as a
1388 cell is not known to be a valid pair.
1390 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1392 * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1): Removed
1393 ASRTSYNTAX. Using SCM_ASSYNT instead.
1395 (scm_m_body): Don't create a redundant cons cell.
1397 (scm_m_do): Removed redundant test 'bodycheck'.
1399 (bodycheck): Removed.
1401 * stacks.c (stack_depth, read_frame, read_frames): Removed
1402 redundant calculation of size, minimized some variable scopes.
1404 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1406 * pairs.c (scm_cons, scm_cons2): Use SCM{_SET}?_CELL_OBJECT as
1407 long as a cell is not known to be a valid pair.
1409 (scm_pair_p): Eliminated redundant SCM_IMP test.
1411 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1413 * eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,
1414 scm_deval_args): Eliminated redundant SCM_IMP tests.
1416 * hashtab.c (scm_ihashx, scm_sloppy_assx, scm_delx_x), weaks.c
1417 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
1418 scm_make_doubly_weak_hash_table): Fixed critical sections.
1419 Thanks to Keisuke Nishida.
1421 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1423 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
1424 Fixed some goto-related initialization bugs (introduced by me).
1426 2000-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
1428 * numbers.h (SCM_INUM0): Uses SCM_MAKINUM instead of SCM_PACK.
1430 * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj): Removed.
1432 (DYNL_FILENAME, DYNL_HANDLE): Use SCM_CELL... macros instead of
1435 (SET_DYNL_HANDLE): Added.
1437 (scm_dynamic_object_p): Simplified.
1439 (scm_dynamic_unlink, scm_dynamic_func): Changed comment. Deliver
1440 better error message when accessing unlinked dynamic objects.
1441 Eliminated call to get_dynl_obj.
1443 2000-05-03 Marius Vollmer <mvo@zagadka.ping.de>
1445 * scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
1446 be an array of function pointers instead of being a pointer to an
1447 array returning function. Thanks to Kalle Olavi Niemitalo!
1449 2000-05-03 Dirk Herrmann <D.Herrmann@tu-bs.de>
1451 * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
1452 (scm_divbigbig, scm_divbigint): Don't return zero any more to
1453 indicate that a division has a remainder, return SCM_UNDEFINED
1454 instead. It is improbable that anyone actually used these
1455 functions outside of numbers.c. For this reason and due to the
1456 change in behaviour the functions are static now. Thus, if
1457 surprisingly there are users of these functions they will at least
1460 * numbers.c: Removed #ifdef SCM_BIGDIG #endif in those functions,
1461 that already have a clean dispatch order. Note: SCM_BIGDIG is
1464 * numbers.c (scm_inexact_p): Simplified.
1466 * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
1467 scm_product, scm_num2dbl, scm_angle): Reordered dispatch
1468 sequence, thereby fixing some comparisons of SCM values with
1471 * numbers.c (scm_divide): Division by zero of inums leads to an
1472 error now. (Formerly, an infinite number was returned.)
1474 Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
1475 if a division has a remainder.
1477 2000-05-02 Gary Houston <ghouston@arglist.com>
1479 * Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).
1481 2000-05-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
1483 * numbers.c (scm_logtest, scm_division): Reordered dispatch
1484 sequence, thereby fixing some comparisons of SCM values with
1487 * numbers.h (scm_makdbl): Mark as deprecated at the point of
1490 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_double2scm,
1491 gh_doubles2scm), numbers.c (scm_istr2flo, scm_max, scm_min,

1497 scm_random_uniform, scm_random_normal_vector_x, scm_random_exp),
1498 struct.c (scm_struct_ref), unif.c (scm_array_to_list): Replace
1499 call to scm_makdbl with a call to scm_make_real or
1500 scm_make_complex, depending on whether the imaginary part is known
1503 2000-05-01 Gary Houston <ghouston@arglist.com>
1505 * scmsigs.c: fix the definition of orig_handlers for the case
1506 that HAVE_SIGACTION is not defined (thanks to
1507 Kalle Olavi Niemitalo).
1509 * Makefile.am: remove include_HEADERS (was libguile.h)
1510 libguile.h: moved to top level directory.
1512 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1514 * numbers.c (SCM_SWAP): Moved to the top of the file to allow for
1517 * numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,
1518 scm_logxor): Reordered dispatch sequence, thereby fixing some
1519 comparisons of SCM values with integer constants.
1521 * number.c (scm_logtest): Removed some redundant SCM_{N}?IMP
1524 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1526 * numbers.c (scm_quotient, scm_remainder): Removed code that was
1527 conditionally compiled based on BADIVSGNS. BADIVSGNS does not
1528 occur anywhere else throughout guile.
1530 * numbers.c (scm_quotient): Fixed parameter number in error
1533 * numbers.c (scm_remainder): Reordered dispatch sequence.
1535 2000-04-25 Gary Houston <ghouston@arglist.com>
1537 * posix.c (scm_execlp): docstring fix (thanks to Martin
1540 2000-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1542 * eval.c (undef_object): Made into a local static variable
1543 (suggested by Jost Boekemeier).
1545 2000-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1547 * pairs.c (cxrs, scm_init_pairs): Simplify initialization of
1550 * procs.c (scm_init_iprocs), procs.h (scm_subr, scm_iproc,
1551 scm_dsubr, scm_init_iprocs): Removed.
1553 * procs.h (SCM_SUBRF, SCM_DSUBRF): Access the cell words
1554 directly instead of casting a cell to a C struct.
1556 2000-04-22 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1558 Better modularization of GC extensions through new C level GC
1561 * weaks.c (scm_weaks_prehistory): New function: Add

1570 * guardians.h (scm_guardian_gc_init, scm_guardian_zombify): Are
1573 * guardians.c (scm_guardian_gc_init): Turned into a hook function
1574 and added to scm_before_mark_c_hook.
1575 (scm_guardian_zombify): Turned into a hook function and added to
1576 scm_before_sweep_c_hook.
1578 * async.c (scm_sys_gc_async_thunk): Run after-gc-hook.
1579 Added #include "libguile/gc.h".
1581 * gc.h: Added #include "libguile/hooks.h".
1583 * gc.c: Removed #include "libguile/guardians.h".
1584 (scm_before_gc_c_hook, scm_before_mark_c_hook,
1585 scm_before_sweep_c_hook, scm_after_sweep_c_hook,
1586 scm_after_gc_c_hook): New C level hooks.
1587 (scm_after_gc_hook): New Scheme level hook.

1616 the root build directory.
1618 * numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG

1647 * gc.c (which_seg): Use SCM2PTR to convert a non immediate SCM

1930 2000-04-04 Michael Livshin <mlivshin@bigfoot.com>
1932 * async.h: kill the scm_async_t struct. having a heap cell
1933 pretending to be a C struct is not helthy, and is not needed here

2004 separate loop after processing all the currently known live
2005 guardians, so as to not introduce order dependencies (thanks to
2006 Gary Houston). note that the order problems are still there if
2007 some guardians are themselves zombies, but that's a sick case that
2008 I'm not going to worry about.
2009 also, make another outer loop to process zombified
2010 guardians (which are uncovered while marking zombies).

2090 SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): Don't initialize globals
2091 and static variables at their point of declaration, but rather in
2094 * tags.h (SCM_PACK): Automatically cast to scm_bits_t.
2096 2000-04-02 Gary Houston <ghouston@arglist.com>
2098 * guardians.c (TCONC_IN, scm_make_guardian): set the CDR of the
2099 empty tconc pair to SCM_EOL instead of SCM_BOOL_F, avoiding the
2100 use of an improper list (which breaks g_print. g_print isn't
2102 guardians.c: Added more comments and modified the make-guardian
2103 docstring. Reordered a few procedures.
2105 2000-04-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
2107 * eval.c (scm_lookupcar1, scm_lookupcar, scm_m_case, scm_m_cond,
2108 scm_m_lambda, iqq, scm_m_define, scm_m_expand_body, unmemocopy,
2109 SCM_CEVAL), procs.h (SCM_TOP_LEVEL): Don't use C operators to
2112 (scm_makprom): Smob data is of type scm_bits_t.
2114 2000-03-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
2116 * backtrace.c (display_error_body), debug.c (scm_procedure_source,
2117 scm_reverse_lookup), dynl.c (scm_dynamic_link): Don't use C
2118 operators to compare SCM values.

2121 SCM_SET_DEBUGOBJ_FRAME): Update SCM_{SET_}?DEBUGOBJ_FRAME to
2122 access raw cell data with SCM_{SET_}?CELL_WORD_1.
2124 * debug.c (scm_make_debugobj): Don't use SCM_SETCAR to set types.
2126 * debug.c (scm_make_memoized), dynl.c (scm_dynamic_link): Smob
2127 data is of type scm_bits_t.
2129 2000-03-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
2131 * gdbint.c (gdb_maybe_valid_type_p), guardians.c (TCONC_EMPTYP,
2132 scm_guardian_zombify): Use SCM_EQ_P to compare SCM values.
2134 * guardians.c (GUARDIAN): Use SCM_CELL_WORD_1 for raw data.
2136 2000-03-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
2138 * ports.h (scm_port): Change type of stream member to scm_bits_t.
2140 * gdbint.c (unmark_port, remark_port), ports.c (scm_markstream),
2141 strports.c (st_resize_port, scm_mkstrport), vports (sf_flush,
2142 sf_write, sf_fill_input, sf_close, scm_make_soft_port): Since
2143 streams are now of type scm_bits_t, SCM streams have to be
2146 * ports.h (SCM_SETPTAB_ENTRY, SCM_SETSTREAM): Cast input to
2149 2000-03-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2151 * coop-defs.h (struct coop_t): Added `sto'-field again because of
2152 binary compatibility---let's remove it next time we alter some
2155 * coop.c (coop_quitting_p, coop_cond_create, coop_mutex_create,
2156 coop_mother, coop_child): New variables.
2157 (mother): New function.
2158 (coop_create): New thread spawning mechanism which uses a "mother
2159 thread". The "dummy" pthreads aren't healthy enough to give birth
2160 to new threads since Linux threads thinks they are asleep.
2162 * coop-defs.h (struct coop_t): Removed dummy_mutex.
2164 * coop-defs.h, coop-threads.c (struct coop_t): Eliminate
2165 `sto'-field when GUILE_PTHREAD_COMPAT is enabled.
2167 2000-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
2169 * arbiters.c (scm_make_arbiter), async.c (scm_async), dynwind.c
2170 (scm_internal_dynamic_wind): Smob data is always of type
2173 * arbiters.c (SCM_ARB_LOCKED, SCM_LOCK_ARB, SCM_UNLOCK_ARB):
2174 Access the locking information in cell entry 0 with
2175 SCM_{SET_}?CELL_WORD_0 instead of SCM_*CAR.
2177 * async.c (scm_run_asyncs): Use SCM_NULLP to test for the empty
2180 * dynwind.c (scm_dowinds): Use SCM_EQ_P to compare SCM values.
2182 * ports.h (SCM_PTAB_ENTRY, SCM_SETPTAB_ENTRY): Access the ptab
2183 entry data using SCM_{SET_}?CELL_WORD_1 instead of SCM_{SET}?CDR.
2185 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2187 * alist.c (scm_sloppy_assq, scm_assq), eq.c (scm_eq_p, scm_eqv_p,
2188 scm_equal_p), list.c (scm_ilength, scm_last_pair, scm_reverse,
2189 scm_sloppy_memq, scm_delq_x, scm_delq1_x), tags.h (SCM_UNBNDP):
2190 Don't use C operators == and != to compare SCM values, use
2193 * boolean.c (scm_boolean_p): Use SCM_BOOLP to determine whether a
2194 SCM value is equal to #t or #f.
2196 * eq.c (scm_eqv_p, scm_equal_p): Don't use SCM_CAR to access the
2197 cell type entry of non immediate objects of unknown type. Use
2198 SCM_CELL_TYPE instead.
2200 * gh_data.c (gh_scm2bool, gh_module_lookup), list.c
2201 (scm_sloppy_memv, scm_sloppy_member, scm_delv_x, scm_delete_x,
2202 scm_delv1_x, scm_delete1_x), scmsigs.c (scm_sigaction): Use
2203 SCM_FALSEP and SCM_TRUE_P to compare SCM values against #f and
2206 * list.c (scm_listify): Use SCM_UNBNDP to test for an unbound
2209 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2211 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread,
2212 scm_make_mutex, scm_make_condition_variable): Cast data to
2213 scm_bits_t in SCM_SET_CELL_WORD and SCM_NEWSMOB macros.
2215 * coop.c (coop_create): Set `specific' field, not `data' to NULL.
2217 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2219 * smob.h (SCM_NEWSMOB, SCM_NEWSMOB2, SCM_NEWSMOB3, SCM_SMOB_DATA,
2220 SCM_SET_SMOB_DATA, SCM_TC2SMOBNUM, SCM_SMOBNUM): To access smob
2221 data, use SCM_{SET_}?CELL_TYPE or SCM_{SET_}?WORD_[1-3].
2223 Note that this implies that smob data has always to be passed as
2224 values of type scm_bits_t.
2226 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2228 * threads.c (scm_init_threads): Pass 0 size to scm_make_smob_type
2229 for scm_tc16_thread. As the current COOP threads are written, GC
2230 is not supposed to manage storage for threads.
2232 * error.c (scm_error): Don't try to throw an error if
2233 scm_gc_heap_lock is true.
2235 * coop.c (coop_finish): New function. Called at exit.
2236 (coop_aborthelp): Free thread structures when threads die.
2237 Finished LinuxThreads compatibility support => COOP threads now
2238 mesh with LinuxThreads.
2240 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread):
2241 Changed SETCDR --> SET_CELL_WORD_1.
2243 * coop-threads.c (scheme_launch_thread): Set word 1 of handle to 0
2246 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2248 * boolean.h (SCM_TRUE_P): New macro.
2250 * boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP), pairs.h
2251 (SCM_NULLP, SCM_NNULLP): Use SCM_EQ_P to compare SCM values.
2253 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2255 * continuations.h (SCM_CONTREGS, SCM_SET_CONTREGS): New macros to
2256 access continuation data.
2258 (SCM_SETJMPBUF): Deprecated. Use SCM_SET_CONTREGS instead.
2260 (SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE, SCM_BASE, SCM_SEQ,
2261 SCM_DFRAME): Use SCM_CONTREGS instead of SCM_CHARS to access
2264 * continuations.c (scm_make_cont), init.c (start_stack),
2265 root.c (scm_internal_cwdr): Use SCM_SET_CONTREGS instead of
2268 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2270 * symbols.h (SCM_LENGTH, SCM_SETLENGTH): Access the length field
2271 of strings and symbols by using SCM_{SET_}?CELL_WORD_0.
2273 (SCM_CHARS, SCM_UCHARS, SCM_SETCHARS): Use SCM_{SET_}?CELL_WORD_1
2274 to access the char * field of strings and symbols.
2276 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2278 * gc.h (SCM_NEWCELL, SCM_NEWCELL2): Use SCM_SET_CELL_TYPE to set
2279 the type entry of a new cell. Added a comment about things to
2280 remember when updating the list of free cells.
2282 (SCM_FREEP, SCM_MARKEDP): Use SCM_CELL_TYPE to access the type
2285 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2287 * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR): Use
2288 SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT. This change implies that
2289 with strict type checking enabled these macros will only work if
2290 given valid SCM parameters.
2292 (SCM_GCCDR): Moved to tags.h.
2294 * tags.h (SCM_GCCDR): Moved here from pairs.h.
2296 2000-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
2298 * tags.h (SCM2PTR, PTR2SCM): Moved to gc.h.
2300 * pairs.h (scm_cell, SCM_CELLPTR, SCM_CELL_WORD*, SCM_CELL_OBJECT*,
2301 SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*, SCM_CELL_TYPE,
2302 SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK, SCM_PTR_GT,
2303 SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC, SCM_NEWCELL,
2304 SCM_NEWCELL2): Moved to gc.h.
2306 (SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR, SCM_SETAND_CDR,
2307 SCM_SETOR_CAR, SCM_SETOR_CDR): Moved to gc.h. These names should
2308 be changed, though, since the macros are not only pair related.
2312 * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,
2313 SCM_CELL_OBJECT*, SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*,
2314 SCM_CELL_TYPE, SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK,
2315 SCM_PTR_GT, SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC,
2316 SCM_NEWCELL, SCM_NEWCELL2, SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR,
2317 SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR): Moved here from
2320 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2322 * tags.h (SCM_STRICT_TYPING): New macro that, if defined,
2323 activates strict compile time type checking for variables of
2325 (SCM, SCM_PACK, SCM_UNPACK): Define according to whether
2326 SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
2327 (SCM_EQ_P): Defined as a macro equivalent for eq?.
2329 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2331 * tags.h (SCM_POINTERS_MUNGED): Removed.
2333 * gc.c (scm_gc_sweep, init_heap_seg): Removed use of
2334 SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
2336 2000-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
2338 * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
2339 SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
2340 SCM_SET_CELL_TYPE): Added a set of low level macros for accessing
2342 (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
2344 * procs.h, procs.c: Instead of SCM_{SET_}?CELL_WORD[12], use the
2345 newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
2347 2000-03-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2349 * tags.h: Disabled definition of SCM_VOIDP_TEST.
2351 Defining SCM as void * introduces problems which haven't been
2352 handled yet. Developers who work with these issues can enable it
2353 in their working copies.
2355 Disabling this definition exposes a set of newly introduced and
2356 older misuses of types which causes warning messages during
2357 compilation. We'll fix this successively.
2359 * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
2360 in order to obtain a value of type SCM.
2361 (scm_cellp): Updated with new changes to scm_mark_locations.
2363 * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
2365 * continuations.c (scm_make_cont): Removed cast of size_t into
2368 * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
2370 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2372 * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for
2373 shifting, not constant. Thanks to Dale P. Smith.
2375 * numbers.c (scm_sum, scm_difference): Don't test a SCM value
2376 for being less than zero. Decode it to a C value first. Again,
2379 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2381 * numbers.h, ramap.c, struct.h, vectors.h: Don't use SCM2PTR for
2382 non scheme values. If raw data is stored in SCM variables, it has
2383 to be accessed using SCM_UNPACK until a better solution is found.
2385 2000-03-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2387 * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
2388 pointer-arithmetic induced by the SCM_PACK/UNPACK change.
2390 * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
2392 * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
2394 * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
2396 * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
2398 * async.c, __scm.h: Removed lots of the old async click logic. It
2399 is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
2400 __scm.h. Let's try this out and dump the old code after the
2401 threads reorganization.
2402 (set-tick-rate, set-switch-rate): Conditionally removed.
2404 2000-03-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2406 * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
2407 made SCM values into pointers. This turned an arithmetic
2408 computation of the address of the vcell into a pointer-arithmetic
2409 one, thereby screwing up marking of structs.
2410 Bugfix 2: Removed incompletely introduced loop variable `j' used
2411 when protecting the tail array of a struct.
2413 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2415 * struct.h (SCM_STRUCT_DATA): Don't cast SCM values to pointers.
2417 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2419 * symbols.h, symbols.c (scm_strhash): Declare the string
2420 parameter as constant, since it is not modified.
2422 * symbols.c (scm_intern_obarray_soft,
2423 scm_sysintern0_no_module_lookup): Can now pass constant strings
2424 to scm_strhash without need for casting.
2426 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2428 * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS): Don't cast SCM
2429 values to pointers. Use SCM2PTR instead.
2431 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2433 * async.c (scm_set_tick_rate, scm_set_switch_rate): Don't unpack
2434 results of SCM_INUM.
2436 2000-03-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2438 * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
2439 GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
2440 GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
2442 * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
2443 min_yield_fraction, min_yield, adjust_min_yield): Renamed from
2444 SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
2445 gc_trigger, adjust_gc_trigger.
2447 * gc.c (alloc_some_heap): Further improvement of minimal heap size
2449 (SCM_MAX): New macro.
2450 (scm_freelist_t): New field: collected_1. Previous amount of
2452 (gc_sweep_freelist_finish): Trigger based on two last values of
2453 freelist->collected to avoid unnecessary allocation due to
2455 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
2456 Adjusted to 45000 cells, 40% and 40%. Gives quick startup
2457 without extra heap allocation.
2459 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2461 * numbers.h (SCM_MAKINUM): The parameter to SCM_MAKINUM should
2462 already be a C value. No need to unpack it.
2464 * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t
2465 if we know it fits into an inum.
2467 * ramap.c (ramap_rp): An scm_tc7_[ui]vect object does point to a
2468 field of long values. In contrast, SCM_VELTS accesses a field of
2471 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2473 * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
2475 (scm_gc_yield_1): New variable: Holds previous yield. Used to
2476 make better judgements.
2477 (gc_sweep_freelist_finish): Inserted explanation of use of
2480 * print.h, stacks.h, options.c, options.h: Changed C++
2483 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2485 * tags.h (SCM2PTR, PTR2SCM): Use SCM_PACK / SCM_UNPACK correctly.
2487 * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
2488 SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS): Use SCM_PACK /
2489 SCM_UNPACK / SCM2PTR correctly.
2491 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2493 * gc.c (adjust_gc_trigger): Improved documentation.
2494 (alloc_some_heap): Since gc_trigger is used against
2495 freelist->collected, this is the value which should be used to
2496 predict minimum growth.
2498 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2500 * eval.h: Fix mixup of packed/unpacked SCM values. (Thanks
2501 Thien-Thi Nguyen for the patch.)
2503 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2505 * numbers.c (scm_ash): Fixed typing problems with the second
2506 parameter and added some documentation. (Thanks Thien-Thi Nguyen
2507 for indicating the problem.)
2509 2000-03-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2511 * gc.c, gc.h (scm_gc_yield): New variable.
2512 (adjust_gc_trigger): Use scm_gc_yield.
2513 (alloc_some_heap): Use scm_gc_yield instead of
2514 scm_gc_cells_collected.
2516 * coop-threads.c: Addd #include "root.h", #include "strings.h".
2518 * debug.c: Added #include "root.h". (Thanks to Thien-Thi Nguyen.)
2520 * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
2521 trigger adjustmeant: Take yield (freed cells) for all freelists
2523 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
2524 to 50000 cell heap with 45% trigger.
2525 (scm_gc_cells_collected): Reintroduced.
2526 (SCM_HEAP_SIZE): New macro.
2527 (scm_gc_sweep): Reintroduced correct computation of
2528 scm_cells_allocated.
2529 (scm_freelist_t): Corrected commentary for field `cluster_size':
2530 Clustersize counts objects, not cells; New member
2531 `clusters_allocated'.
2533 2000-03-19 Michael Livshin <mlivshin@bigfoot.com>
2535 * *.[hc]: add Emacs magic at the end of file, to ensure GNU
2538 2000-03-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2540 * threads.h: Added #include "libguile/throw.h". (Thanks to
2543 2000-03-18 Michael Livshin <mlivshin@bigfoot.com>
2545 * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
2546 names, anyone got any better ones?)
2548 * gc.h: (typedef struct scm_freelist_t) remove from here.
2550 * gc.c: (CELL_UP, CELL_DN) made these macros take additional
2551 parameter (the span).
2552 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
2553 (typedef struct scm_freelist_t) moved here from gc.h, it had no
2554 business being externally visible.
2555 (typedef struct scm_heap_seg_data_t) renamed from
2556 scm_heap_seg_data, to be style-compliant.
2557 (scm_mark_locations) if the possible pointer points to a
2558 double-cell, check that it's properly aligned.
2559 (init_heap_seg) align double-cells properly, work with the
2560 assumption that the segment size divides cleanly by cluster size.
2561 (round_to_cluster_size) new function.
2562 (alloc_some_heap, make_initial_segment) use round_to_cluster_size
2563 to satisfy the new init_heap_seg invariant.
2565 2000-03-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
2567 * _scm.h: Don't include async.h everywhere...
2569 * eq.c eval.c iselect.c: ... only include it here.
2571 2000-03-18 Dirk Herrmann <D.Herrmann@tu-bs.de>

2622 2000-03-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2624 * gc.c, gc.h: Cleanup of the change of 2000-03-15.
2625 Cluster sizes are now independent of GC trigger values.
2626 GUILE_GC_TRIGGER_n can now specify a relative trigger value:
2627 A negative integer gives fraction of total heap size in percent.
2628 (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
2630 * init.c (scm_boot_guile_1): Introduced new variable
2631 GUILE_MAX_SEGMENT_SIZE; New environment variable names:
2632 GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
2633 GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
2635 2000-03-16 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2637 * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
2638 freeing of segment work with the new GC scheme. (Thanks to
2639 Michael Livshin.) Oops, also happened to make GUILE_NEW_GC_SCHEME
2640 the default, but I'll let this change stay in CVS Guile since this
2641 code is not expected to contain serious bugs.
2643 2000-03-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2645 * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
2647 (scm_free_list_length): New procedure (GUILE_DEBUG).
2648 Fixed a small but serious bug introduced by the previous change.
2650 * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
2651 loop and declare as register.
2653 * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
2656 Wed Mar 15 08:27:04 2000 Greg J. Badros <gjb@cs.washington.edu>
2658 * fluids.c: Docstring patch from Keisuke Nishida. Some
2659 reindentation, too, and a couple formals renamed. Should
2660 fluid-set! return UNSPECIFIED instead of a value?
2662 Wed Mar 15 08:24:58 2000 Greg J. Badros <gjb@cs.washington.edu>
2664 * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
2665 generate the latter from the concrete listing of the former. Then
2666 make guile-procedures.txt depend on DOT_DOC_FILES instead of
2667 *.doc, so that rebuilding it works.
2669 Wed Mar 15 08:12:14 2000 Greg J. Badros <gjb@cs.washington.edu>
2671 * libguile.h: Include libguile/validate.h. Thanks Keisuke Nishida!
2673 * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
2674 with nothing and \n, respectively. Thanks Keisuke Nishida for
2675 noticing this problem.
2677 2000-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2679 * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
2680 new way of allocating heap. It makes Guile fast, but still
2683 * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
2684 allocating heap. The basic idea is to trigger GC every Nth
2685 allocated cell and grow heap when free list runs out. The scheme
2686 has been extended so that GC isn't triggered until all remaining
2687 cells are used. The implementation is also prepared for
2688 development in the direction of POSIX threads.
2690 * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
2691 SCM_EXPHEAP should return half of the heap size.
2693 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2695 The following change to init.c is only enabled if Guile was
2696 configured with --enable-guile-debug.
2698 * init.c (scm_i_getenv_int): New function.
2699 (scm_boot_guile_1): Use the environment variables
2700 GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
2701 they exist. (This may be replaced by a Scheme level mechanism in
2704 * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
2705 scm_assoc. (Thanks to Keisuke Nishida.)
2707 2000-03-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2709 * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
2710 scm_nil, scm_t. (Thanks to Keisuke Nishida.)
2712 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2714 * init.c (scm_boot_guile_1): Use same initial segment size for
2715 1-word and 2-word segments. Having the smaller size causes Guile
2716 to GC too often. Obviously something needs to be done to allow
2717 for a smaller 2-word segment without this to happen. (The amount
2718 of heap for each type should be automatically adapted to the
2719 application somehow.)
2721 [Almost all of these changes should be documented in the NEWS
2724 * gc.h (scm_freelist_t): New type.
2726 * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
2728 * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
2729 all of Guile basics fits into one segment and there suitable room
2731 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
2733 (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
2734 Freelists now contains information about object span, cells
2735 collected and amount of cells in heap segments belonging to the
2737 (scm_heap_size, scm_gc_cells_collected): Removed.
2739 * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
2741 * Makefile.am (libguile_la_LDFLAGS): Bumped library version
2744 * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
2745 numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
2746 rewrite of handling of real and complex numbers.
2747 (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
2748 removed along with the support for floats. (Float vectors are
2751 * tags.h (scm_tcs_bignums): Removed.
2752 (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
2753 Use SCM_BIGSIGN(x) to test for sign!
2754 (scm_tc16_big): The new bignum type.
2755 (SCM_REAL_PART, SCM_IMAG_PART): Removed.
2757 * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
2758 (scm_makdbl): Deprecated.
2759 (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
2760 (SCM_SINGP): Deprecated.
2762 (SCM_INEXP, SCM_CPLXP): Deprecated.
2763 (SCM_INEXACTP, SCM_COMPLEXP): New macros.
2764 (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
2765 SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
2766 (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
2767 for doubles and complex numbers.
2768 (SCM_REAL_VALUE): New selector for doubles.
2769 (scm_double_t, scm_complex_t): New types.
2772 * numbers.c (scm_floprint, scm_floequal): Removed.
2773 (scm_print_real, scm_print_complex, scm_real_equalp,
2774 scm_complex_equalp): New functions.
2776 * unif.c (scm_makflo): Removed.
2778 * smob.h (SCM_SMOB_PREDICATE): New macro.
2779 (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
2780 SCM_RETURN_NEWSMOB3): New macros.
2782 1999-11-21 Michael Livshin <mlivshin@bigfoot.com>
2784 The following changes implement primitive support for double cells
2785 (i.e. four-word cells) and change the representation of some
2786 things to multi-cells instead of cons+malloc. (Applied and
2789 * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
2790 (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
2791 multi-cell access macros (used by the ones below).
2792 (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
2795 * gc.c (scm_freelist2): multi-cell freelists.
2796 (inner_map_free_list): map_free_list, parameterized on ncells.
2797 "nn cells in segment mm" was misleading for ncells > 1; changed to
2798 "objects". still print cells too, though.
2799 (scm_map_free_list): rewritten using inner_map_free_list.
2800 (scm_check_freelist): get freelist as parameter, since now we have
2802 (scm_debug_newcell2): multi-cell variants of
2804 (scm_gc_for_newcell): take ncells and freelist pointer as
2806 (scm_gc_mark): add case for tc7_pws (procedures with setters are
2808 (scm_gc_sweep): don't free the float data, since it's not malloced
2810 (init_heap_seg): didn't understand what n_new_objects stood for,
2811 so changed to n_new_cells.
2812 (make_initial_segment): new function, makes an initial segment
2813 according to given ncells.
2814 (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
2816 * numbers.c (scm_makdbl): no malloc'ing needed, so the
2817 {DEFER,ALLOW}_INTS thing removed.
2819 * numbers.h (struct scm_dbl): changed to represent a double cell,
2820 with the number in the second half.
2822 * dynwind.c: changed the wind-guards representation to double
2825 * procs.c, procs.h: changed the procedure-with-setter representation
2828 * async.c, async.h: made async representation a double cell.
2830 * dynl.c: made dynamic_obj representation a double cell.
2832 2000-03-13 Gary Houston <ghouston@arglist.com>
2834 * ports.c (flush_void_port): renamed to flush_port_default.
2835 (end_input_void_port): renamed to end_input_default.
2837 * init.c (scm_standard_stream_to_port): create a void port instead
2838 of opening /dev/null if the standard file descriptors are bad.
2839 advantages: no portability problems, doesn't waste a file descriptor,
2840 simplifies the code (thanks to Marius for the idea).
2842 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
2844 * void ports: make reading from a void port give EOF instead of
2846 * ports.c (s_scm_sys_make_void_port): modified docstring.
2847 (fill_input_void_port): new proc.
2848 (scm_init_ports): set up fill_input_void_port.
2849 * ports.c (scm_port_non_buffer): new proc.
2850 (scm_void_port): call scm_port_non_buffer.
2852 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
2853 which was incorrectly appended.
2855 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2857 * guile-doc-snarf.in: Don't use absolute path for `sed'. (Note
2858 that we can't use autoconf for this. Autoconf itself relies on
2859 the existence of `sed' somewhere on your path.) (Thanks to Dirk
2862 2000-03-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2864 * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
2865 EXTRA_libguile_la_SOURCES.
2867 * iselect.h: Always declare scm_internal_select.
2869 * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
2870 end. Also let scm_internal_select be a real function also when
2873 * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
2875 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2877 * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
2878 SCM_ASYNC_TICK. (This is a preparation for POSIX threads support,
2879 and kind of an experiment: Will this cause problems?)
2881 Sun Mar 12 13:26:30 2000 Greg J. Badros <gjb@cs.washington.edu>
2883 * Makefile.am: Added *.doc to DISTCLEANFILES.
2885 2000-03-12 Gary Houston <ghouston@arglist.com>
2887 * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
2888 the fdes is valid before doing anything else. check that
2889 the file descriptor supports the modes required.
2890 (scm_fport_buffer_add): don't throw an error if fstat doesn't
2891 work: just use the default buffer size.
2893 * throw.c: change an outdated comment about scm_internal_catch
2894 BODY: it doesn't take a jumpbuf arg.
2896 * init.c (scm_standard_stream_to_port): install a handler in case
2897 scm_fdes_to_port throws an error. don't check here whether the
2898 file descriptor is valid, since scm_fdes_to_port will do that.
2899 set the revealed count depending on whether the port got the
2900 standard file descriptor.
2901 (stream_body_data): new type.
2902 (stream_body, stream_handler): new procs.
2904 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2906 * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
2907 Renamed from SCMWORD.
2909 * tags.h (SCM_NCELLP): Removed (SCMWORD).
2911 * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
2913 * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
2914 feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,

2919 throw.c, unif.c, unif.h, variable.h, vectors.h, weaks.c,
2920 weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
2921 SCM_ASSCM, SCM_ASWORD, SCM_CARW).
2923 * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
2925 * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
2926 tags.h: Fixed copyright notices.
2928 * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
2930 2000-03-12 Marius Vollmer <mvo@zagadka.ping.de>
2932 * init.c (scm_standard_stream_to_port): Check whether the file
2933 descriptor is valid and substitute "/dev/null" when not.
2935 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2937 * coop-defs.h (struct timespec): Conditionally defined.
2939 * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
2942 * readline.c (match_paren): Bugfix: First arg to select is not
2943 number of descriptors but the number of the highest descriptor +
2946 This is a preliminary attempt at a cleanup of the threads support
2947 code. It moves things to better places, makes arguments more
2948 consistent with the POSIX API (which is used in GNOME's glib), and
2949 adds new functionality.
2951 * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
2953 * coop-defs.h (scm_mutex_trylock): New macro: alias for
2955 (scm_cond_init): Changed definition to
2956 coop_new_condition_variable_init.
2958 * coop.c: #include <errno.h>
2959 (coop_timeout_qinsert): Moved here from iselect.c
2960 (coop_new_mutex_init, coop_new_condition_variable_init): New
2961 functions. The strange names are temporary. Use scm_mutex_init
2962 and scm_cond_init instead.
2963 (coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
2964 is ANSI C, but should we check for individual error codes in
2966 (coop_condition_variable_timed_wait_mutex): New function.
2967 (coop_key_create, coop_setspecific, coop_getspecific,
2968 coop_key_delete): New functions.
2970 * iselect.c (coop_timout_qinsert): Moved to coop.c
2972 2000-03-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2974 * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
2975 SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
2977 * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
2980 * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
2981 SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
2982 proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
2984 * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
2987 2000-03-11 Dale P. Smith <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
2989 * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
2990 scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
2991 logical functions from SCM.
2993 (logand, logior, logxor, logtest, logbit?): Extended scheme
2994 logical functions to use bignums from SCM.
2996 (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
2997 lognot from using bignums.
2999 Thu Mar 9 11:33:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3001 * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
3002 eliminating some warnings.
3004 * unif.c, strports.c, print.c, options.c: Fix some warnings on
3007 * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
3008 what the scm_return_first* functions do.
3010 2000-03-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
3012 * libguile/*.[ch]: make a distinction between SCM as a generic
3013 name for a Scheme object (now a void*), and SCM as 32 bit word for
3014 storing tags and immediates (now a long int). Introduced
3015 SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
3016 code in the process: arbiter.c (use macros), unif.c (scm_array_p),
3018 Wed Mar 8 10:15:59 2000 Greg J. Badros <gjb@cs.washington.edu>
3020 * numbers.c: Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
3021 various logXXX primitives. Thanks Eric Moore!
3023 Tue Mar 7 08:05:22 2000 Greg J. Badros <gjb@cs.washington.edu>
3025 * run-test, remaining-docs-needed: Added these scripts. The
3026 second one is only temporary until the docstring additions are
3027 complete. run-test may best live on, but is here mostly for
3028 convenience and awareness for now.
3030 * hash.c: Docs, minor cleanup patch from Dirk Herrman.
3032 Thu Mar 2 16:06:58 2000 Greg J. Badros <gjb@cs.washington.edu>
3034 * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
3035 displaying the expected type. Use SCM_LISTn in a couple places
3036 instead of scm_cons-ing by hand.
3038 * __scm.h: Added SCM_ASSERT_TYPE macro.
3040 * validate.h, scm_validate.h: Added the former, as a renamed
3041 version of the latter with SCM_ASSERT_TYPE used in
3042 SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
3044 * Makefile.am: Rename scm_validate.h to validate.h.
3046 * *.c, *.h: Include validate.h, not scm_validate.h (old name's
3047 prefix was superfluous).
3049 Thu Mar 2 15:33:12 2000 Greg J. Badros <gjb@cs.washington.edu>
3051 * hashtab.c: Improved documentation for lots of functions. Added
3052 handwritten docs for `hash-fold'.
3054 Thu Mar 2 15:13:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3056 * list.c: Added hand-written docs for `del{q,v,ete}1!'.
3058 Thu Mar 2 12:38:30 2000 Greg J. Badros <gjb@cs.washington.edu>
3060 * list.c: Moved append docs to append! Thanks Dirk Hermann. Also,
3061 added append docs from R4RS.
3063 * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
3064 Thanks Dirk Hermann!
3066 * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
3067 deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
3069 * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
3070 Drop use of SCM_P for function prototypes... assume an ANSI C
3071 compiler. Thanks Dirk Hermann!
3073 Sat Feb 19 12:20:12 2000 Greg J. Badros <gjb@cs.washington.edu>
3075 * ports.c: Made `set-port-column!' and `set-port-line!' each
3076 return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
3077 that caused a seg fault. Also fixed `set-port-column!'s
3078 docstring. Thanks Han-Wen Nienhuys for finding the bug!
3080 Sun Feb 13 19:11:42 2000 Greg J. Badros <gjb@cs.washington.edu>
3082 * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
3083 regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
3084 strings.c, variable.c: Added lots of documentation, cleaned up
3085 some existing documentation. Occasionally changed formal params
3086 to match docs. Also folded an #ifdef into the inners of a
3087 primitive instead of having two copies of the primitive
3088 (`get-internal-real-time', from stime.c)
3090 Sun Feb 13 18:12:19 2000 Greg J. Badros <gjb@cs.washington.edu>
3092 * ports.c: Added docs for primitives missing them. Written by
3095 Sun Feb 13 09:40:36 2000 Greg J. Badros <gjb@cs.washington.edu>
3097 * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
3098 just execing guile-func-name-check. Thanks Michael Livshin!
3100 Thu Feb 10 11:43:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3102 * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
3103 dead code. Patch from Michael Livshin.
3105 * guile-doc-snarf.in: Tweak to work with Sun/HP sh. Patch from
3108 2000-02-09 Gary Houston <ghouston@arglist.com>
3110 * init.c (scm_init_standard_ports): when stdout is a tty, make the
3111 current-output-port unbuffered by default. this is less confusing
3112 for interactive use. it was line-buffered because of a
3113 performance problem with unbuffered ports, but I think it will be
3116 2000-02-08 Gary Houston <ghouston@arglist.com>
3118 * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
3121 * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
3122 HAVE_TZNAME are defined, use an empty string instead of giving two
3123 spurious compile-time errors.
3125 Tue Feb 8 13:57:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3127 * ports.c: Doc patches from Richard Kim. Pasted from MIT Scheme.
3130 Mon Feb 7 09:07:31 2000 Greg J. Badros <gjb@cs.washington.edu>
3132 * macros.c: Doc patches from Richard Kim. Pasted from scm.texi.
3134 Sun Feb 6 20:26:21 2000 Greg J. Badros <gjb@cs.washington.edu>
3136 * pairs.c: Doc patches from Richard Kim. Pasted from MIT Scheme
3137 (which is GNU GPL'd).
3139 2000-01-31 Gary Houston <ghouston@arglist.com>
3141 * strings.h: don't use SCM_P. don't include <string.h>.
3142 * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
3144 * strings.c (scm_string_ref): make the 2nd argument compulsory.
3145 previously it defaulted to zero for no good reason that I can see.
3146 use a local variable for SCM_INUM (k). replace
3147 SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
3149 (scm_makfromstr): cosmetic changes.
3151 (scm_string): Accept only chars in the list, not strings, for
3152 conformance to R5RS (particularly for list->string, which is
3153 supposed to be the inverse of string->list.) remove
3154 SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
3155 scm_makstr handles the cell allocation. when reporting wrong-type
3156 arg, don't report the position as 1.
3158 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
3160 2000-01-29 Gary Houston <ghouston@arglist.com>
3162 * posix.c (scm_pipe): rewrote the docstring.
3164 * filesys.c (scm_select, retrieve_select_type, get_element,
3165 fill_select_type, set_element): modified so that Scheme
3166 "select" tests port buffers for the ability to provide input
3167 or accept output. Previously only the underlying file descriptors
3168 were checked. Rewrote the docstring.
3170 Thu Jan 27 10:14:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3172 * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
3173 from Gregg Reynolds. Thanks Gregg!
3175 Thu Jan 27 09:59:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3177 * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
3178 adding "x" prefix to the line so that guile-func-name-check
3179 doesn't complain unnecessarily.
3181 Wed Jan 26 17:33:52 2000 Greg J. Badros <gjb@cs.washington.edu>
3183 * throw.c: Factor out an #ifdef/#else/#endif choice more finely
3184 for maintainability.
3186 * strop.c: Documentation added by Gregg A. Reynolds. Pasted in
3189 Wed Jan 26 10:02:11 2000 Greg J. Badros <gjb@cs.washington.edu>
3191 * tag.c: Added doc for `tag', but mark as deprecated since Mikael
3192 suggests removing tag.c altogether (and using a new `class-of'
3195 * strings.c: Added documentation from Gregg A. Reynolds. Edited
3196 a bit by me to use FOO instead of @var{foo} and to have the
3197 summary come before preconditions on input. Also dropped trailing
3200 * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
3201 function with scm_make_subr_opt w/ last arg of 0 so it is not
3202 visible at the Scheme level. Mikael says that this is the right
3203 thing because the first arg to the proc is the guts of a compiled
3204 closure and shouldn't be exposed to the Scheme level.
3206 Tue Jan 25 17:15:47 2000 Greg J. Badros <gjb@cs.washington.edu>
3208 * sort.c: typo in comment fixed.
3210 * keywords.c: Added documentation.
3212 * guardians.c: Added documentation (could be better).
3214 * gc.c: Added docs for gc-set-debug-check-freelist.
3216 * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
3218 * boolean.c: Added docs for `not', `boolean?' (by hand).
3220 Tue Jan 25 13:28:56 2000 Greg J. Badros <gjb@cs.washington.edu>
3222 * random.c: Added documentation, from SLIB page:
3223 http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
3225 Mon Jan 24 17:50:20 2000 Greg J. Badros <gjb@cs.washington.edu>
3227 * variable.c, version.c: Added documentation, written by hand
3228 since I could not find anything already written that was
3231 2000-01-23 Gary Houston <ghouston@arglist.com>
3233 * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
3234 not defined (thanks to Richard Y. Kim).
3236 Thu Jan 20 13:00:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3238 * Makefile.in: Removed, this is auto-generated.
3240 Thu Jan 20 11:33:47 2000 Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
3242 * list.c: Put some variable initialization code at the point of
3243 declaration; Added a comment for list*; Formatting changes.
3245 * load.c: use SCM_NNULLP to make sure the end of a list is not
3248 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3250 * backtrace.c (scm_display_error_message): Bugfix: Don't use
3251 result of scm_list_p as C boolean.
3252 (scm_display_error_message, scm_set_print_params_x): Use new
3253 validation macros. (Thanks to Dirk Herrmann.)
3255 * net_db.c (scm_resolv_error): Cast result from hstrerror.
3257 * strports.c (st_end_input): Inserted parenthesis to get operator
3260 * list.h (scm_init_list): Removed SCM_P around prototypes.
3262 * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
3263 filesys.c, posix.c: Converted docstrings to ANSI C format and
3264 escaped " occurring inside string literals.
3266 Tue Jan 18 13:21:08 2000 Mikael Djurfeldt <mdj@r11n07-s.pdc.kth.se>
3268 * posix.c (scm_mknod): Escape " occuring inside docstring.
3270 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3272 * alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,
3273 evalext.c, filesys.c, gc.c, hash.c, hashtab.c, ioext.c,
3274 keywords.c, list.c, load.c, macros.c, net_db.c, numbers.c,
3275 objprop.c, ports.c, posix.c, print.c, procprop.c, procs.c,
3276 ramap.c, regex-posix.c, root.c, scmsigs.c, simpos.c, socket.c,
3277 stacks.c, stime.c, strings.c, strop.c, strports.c, struct.c,
3278 symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
3279 weaks.c: Converted docstrings to ANSI C format.
3281 * filesys.c (scm_chmod), simpos.c (scm_system), version
3282 (scm_version), vports (scm_make_soft_port): Escape " occuring
3285 Mon Jan 17 11:41:22 2000 Greg J. Badros <gjb@cs.washington.edu>
3287 * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
3288 SCM_VALIDATE_LONG_COPY
3290 * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
3291 SCM_VALIDATE_INUM_COPY to let bigger numbers be used. Rename a
3292 couple of formal arguments (and fix their uses) to make arguments
3293 match the documentation.
3295 2000-01-14 <mstachow@alum.mit.edu>
3297 * Makefile.am: Augment path when running guile-doc-snarf so
3298 guile-func-name-check is found.
3300 Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
3302 * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
3303 def, not SCM_MAKINUM(def); thanks Janis Bzerins!
3305 Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3307 * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
3308 the way guile-1.3.4 worked, but #if 0 out the version using
3309 SCM_VALIDATE_INUM_COPY for stricter testing.
3311 Tue Jan 11 18:24:18 2000 Greg J. Badros <gjb@cs.washington.edu>
3313 * guile-doc-snarf.in: Use new $fullfilename for running
3314 guile-func-name-check, and put "$fullfilename" and "$filename" in
3315 quotes at uses to make sure re-splitting on whitespace does not
3316 occur (so filenames w/ embedded whitespace would work okay, though
3317 I sure hope we never have to deal with that! :-) ). Thanks to
3318 Mikael for pointing out the source_dir != build_dir was broken.
3320 Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
3322 * scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
3323 SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
3324 SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
3325 macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
3328 * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
3329 then return whether it's an open port (was validating that it was
3330 an open port -- this was a bug I introduced back in December, but
3331 my careful reading of diffs caught it).
3333 * numbers.c: Recombine the two conditional-compilation paths for
3334 all the log* primitives -- they were split based on #ifndef
3335 scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
3336 some bugs and inconsistencies in the two sets of implementations.
3337 (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
3339 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
3340 SCM_VALIDATE_INUM_COPY once where it should've been used.
3342 * fluids.c (scm_internal_with_fluids): Use
3343 SCM_VALIDATE_LIST_COPYLEN.
3345 * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
3346 this is questionable as it relaxes type safety, but other changes
3347 were useful and all SCM_NUM2LONG's should probably be
3348 revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
3350 * evalext.c: line-break change on 1 line.
3352 * eval.c (nconc2last): Takes a non-empty list as its first
3353 argument, not just a list.
3355 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
3357 Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3359 * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
3360 net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
3363 * symbols.c (scm_sysintern0): Fixed the function name in a
3364 scm_misc_error invocation.
3366 * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
3367 use scm_return_first to ward off latent GC bug that Mikael caught.
3369 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
3370 used before but should've been.
3372 2000-01-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3374 * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
3375 SCM_FUNC_CAST_ARBITRARY_ARGS.
3377 Tue Jan 11 13:44:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3379 * guile-func-name-check.in: Added this script to statically check
3380 #define FUNC_NAME, #undef FUNC_NAME in the source.
3382 * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
3383 redundant comment, semicolon; caught by new guile-func-name-check
3386 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
3387 Caught by new guile-func-name-check-script.
3389 * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
3391 * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
3392 guile-func-name-check.
3394 * guile-doc-snarf.in: Run guile-func-name-check on the file before
3397 Tue Jan 11 11:31:10 2000 Greg J. Badros <gjb@cs.washington.edu>
3399 * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
3400 port function take const void*, not void*.
3402 Tue Jan 11 11:18:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3404 * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
3405 strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
3406 SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
3407 consistency with the other macros dealing with immediate
3408 characters. (Similar to INT -> INUM change a week or so ago).
3410 Tue Jan 11 10:41:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3412 * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
3413 net_db.c, read.c, socket.c: Update error messages to use ~A for
3414 %s, ~S for %S to work with new `simple-format' format and be
3415 standardized better.
3417 * print.h, print.c (scm_simple_format): Added `simple-format'
3418 primitive. It's the old scm_display_error, with ARGS now a rest
3419 parameter, and the destination first instead of last (and a couple
3420 new capabilities inspired by `format' -- #t as destination means
3421 current-output-port, #f means return the formatted text as a
3424 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
3426 * backtrace.c (scm_display_error_message): Rewrote to use
3427 scm_simple_format() procedure.
3429 * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
3431 2000-01-09 Marius Vollmer <mvo@zagadka.ping.de>
3433 Finally applied the libltdl patch from Thomas Tanner, with slight
3436 * DYNAMIC-LINKING: Removed because it is obsolete.
3437 * dynl.c: Use ANSI prototypes.
3438 (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
3439 * scmconfig.h.in: Do not change, as it is automatically generated.
3441 1999-07-25 Thomas Tanner <tanner@ffii.org>
3443 * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
3445 * Makefile.am: likewise, add INCLTDL (libltdl headers) to
3446 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
3448 * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
3449 * guile.c: register preloaded modules
3450 * scmconfig.h.in: remove obsolete symbols
3452 2000-01-09 Gary Houston <ghouston@arglist.com>
3454 * These changes should make it unnecessary to call tzset from
3455 Scheme after modifying the TZ environment variable, even if the
3456 system date facilities cache the value.
3457 * stime.c (setzone, scm_localtime): added comments.
3458 (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
3459 (setzone): don't call tzset.
3460 (restorezone): call tzset only if HAVE_TZSET is defined.
3461 (scm_tzset): don't define if HAVE_TZSET not defined. Change the
3462 doc string to indicate that this procedure isn't likely to do
3464 (scm_localtime, scm_strftime, scm_mktime): call tzset if
3465 LOCALTIME_CACHE is defined.
3467 2000-01-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3469 * posix.c (scm_sync): Return SCM_UNSPECIFIED.
3471 2000-01-09 Gary Houston <ghouston@arglist.com>
3473 * eval.c: define scm_unbound_variable_key ('unbound-variable).
3474 scm_lookupcar1: throw an error with key 'unbound-variable instead
3475 of 'misc-error when an unbound variable is encountered.
3477 * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
3478 scm_symlink, scm_readlink, scm_lstat),
3479 posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
3480 scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
3482 simpos.c (scm_system),
3483 stime.c (scm_times, scm_strptime):
3484 move the HAVE_XXX feature tests out of the procedure bodies.
3485 don't use SCM_SYSMISSING.
3486 scm_validate.h (SCM_SYSMISSING): removed.
3487 error.h, error.c (scm_sysmissing): comment that this is deprecated.
3488 see ChangeLog entry for 1999-12-28.
3490 Sat Jan 8 19:52:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3492 * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
3494 Sat Jan 8 17:06:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3496 * backtrace.c: Fix spelling typo in a comment.
3498 * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
3499 text. Reformatted some of the expansions.
3501 Fri Jan 7 15:50:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3503 * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
3504 report the position of the argument.
3506 * error.h, error.c (scm_out_of_range_pos): Added this function to
3507 take extra "pos" argument, the position number of the errant
3510 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
3512 * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
3513 and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
3514 prefers that and I'm reasonably indifferent.
3516 Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
3518 * snarf.h: Factor out differences between C++ and non-C++ into
3519 SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
3520 definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
3521 Mikael's macros, below, but changed names and SCM_SNARFING no
3522 longer expands to include %%% -- that must appear in the argument
3523 so that the token appears at the call-site as a reminder).
3525 2000-01-07 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3527 * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
3528 snarf macro definitions.
3530 2000-01-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3532 * chars.c (scm_integer_to_char): Use Greg's nice
3533 SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
3536 Thu Jan 6 11:48:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3538 * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
3540 Thu Jan 6 11:22:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3542 * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
3543 instead of GUILE_PROC.
3545 Thu Jan 6 11:21:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3547 * alist.c: Do not report mismatch errors on some uses of `tmp' (do
3548 this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
3551 Thu Jan 6 09:54:33 2000 Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
3553 * scm_validate.h: Remove some redundant NIMP tests.
3555 * alist.c: minimize scope of the tmp variables, and initialize
3556 them when declared. The strange SCM_NIMP tests are replaced by
3557 SCM_CONSP tests that more closely reflect the intended semantics.
3558 However, we don't get a performance penalty here, because the
3559 SCM_CONSP test was performed by the ALISTCELL test anyway. * The
3560 extremely ugly use of ASRTGO macros was removed: The calls to
3561 ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
3562 label parameter that only exists when SCM_RECKLESS is not defined.
3563 This works, because ASRTGO itself is defined in a way that it only
3564 makes use of the label parameter if SCM_RECKLESS is not defined
3565 (shudder!). Does guile make at all use of the possibility to
3566 define SCM_RECKLESS? * Codesize is likely to be reduced, since
3567 instead of two calls to SCM_ASSERT performed by the ALISTCELL test
3568 we now only get one test.
3570 * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
3571 SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
3572 some variables in `list?'. Fix `reverse' and `reverse!'
3573 primitives to handle improper lists better.

3577 * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
3578 macros and SCM_DEFINE macros to match GNU coding standards.
3580 Wed Jan 5 11:04:24 2000 Greg J. Badros <gjb@cs.washington.edu>
3582 * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
3584 Wed Jan 5 10:59:06 2000 Greg J. Badros <gjb@cs.washington.edu>
3586 * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
3587 better consistency with the names of other SCM_VALIDATE_ macros
3588 and better conformance to guile naming policy.
3590 Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
3592 * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
3593 SCM_VALIDATE instead of 1 to avoid a check on the argument (since
3594 it's not the actual name of the formal).
3596 * guile-snarf.awk.in: Do argument/number mismatch checking and
3597 print warnings in an Emacs compile-mode parseable format.
3599 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
3600 SCM_OUTOFRANGE as 3rd argument.
3602 * random.c: Fix argument/number mismatch (that I introduced :-( ).
3604 * __scm.h: Do not #define SCM_ARG* when snarfing;
3605 lets us distinguish between 1 and SCM_ARG1 when snarfing as only
3606 the former (using the number) requires the argument to match the
3607 formal in the current argument snarfing check.
3609 * snarf.h: Give new definition of SCM_ASSERT when in
3610 snarfing mode to output a lexically-identifiable sequence that the
3611 guile-snarf.awk script uses to verify argument/position matching.
3613 * ramap.c: Remove extraneous #undef FUNC_NAME.
3615 Wed Jan 5 08:36:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3617 * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
3618 current version of the same functionality; it writes the .x output
3619 to stdout instead of directly into the file.
3621 Wed Jan 5 08:15:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3623 * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
3624 posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
3625 redundant with the safer macros. Patch from Dirk Hermann applied
3626 by hand. Thanks Dirk!
3628 * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
3631 * ramap.c: whitespace change.
3633 Tue Jan 4 14:21:35 2000 Greg J. Badros <gjb@cs.washington.edu>
3635 * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
3636 removals from Dirk Hermann.
3638 * alist.c: Rename formals to match the parameter names in the
3639 documentation, updates to documentation. Thanks Dirk Hermann!
3641 2000-01-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3643 * eval.c (SCM_CEVAL): Reverse order of
3644 scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
3645 (Thanks to Brad Knotwell.)
3647 Mon Jan 3 08:30:02 2000 Greg Harvey <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
3649 * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
3652 * pairs.h: Added a comment about the need for the SCM_SETCAR in
3655 Mon Jan 3 08:25:19 2000 Greg J. Badros <gjb@cs.washington.edu>
3657 * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
3658 SCM_NIMP tests that were redundant are now eliminated. Patches
3659 from Dirk Hermann applied by hand.
