1 2000-08-25 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
3 * procprop.c: #include "libguile/smob.h"; Check applicable smobs.
5 2000-08-24 Keisuke Nishida <kxn30@po.cwru.edu>
7 * smob.h (scm_smob_descriptor): Added `apply' and `gsubr_type'.
8 * smob.c (scm_make_smob_type): Initialize `apply' and `gsubr_type'.
9 (scm_set_smob_apply): New function.
10 (scm_smob_apply_0, scm_smob_apply_1, scm_smob_apply_2,
11 scm_smob_apply_3): New functions.
12 * eval.c (SCM_CEVAL, SCM_APPLY): Added dispatch for applicable smobs.
13 * procs.c (scm_procedure_p): Check applicable smobs.
15 2000-08-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
17 * Makefile.am (BUILT_SOURCES): Experimentally added scmconfig.h
18 also here. (This is supposed to make sure that scmconfig.h is
19 built before all sources in order to prevent that everything has
20 to be rebuilt again. Hope it works---I'm just guessing. :)
22 * fluids.c (scm_fluid_set_x): Return SCM_UNSPECIFIED.
24 2000-08-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
26 * gc.c (scm_gc_mark): Don't use GUILE_DEBUG flag to compile in
27 extra tests. (GUILE_DEBUG is only supposed to make extra
28 debugging functions available.)
30 2000-08-21 Michael Livshin <mlivshin@bigfoot.com>
32 * gc.h (SCM_GC_CARD_N_CELLS): change to be a nice non-confusing
35 2000-08-19 Michael Livshin <mlivshin@bigfoot.com>
37 * gc.c (scm_gc_sweep): added a `continue' statement that have
38 fallen through the cracks in the merge. thanks to Shuji Narazaki!
40 * gc.h: removed some stuff that broke compilation for people and
41 wasn't actually needed anyway.
43 2000-08-18 Neil Jerram <neil@ossau.uklinux.net>
45 * filesys.c (scm_fcntl): Docstring fix - missing newlines inserted.
47 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_sethost,
48 scm_setnet, setproto, setserv): Argument names changed to match

60 2000-08-18 Neil Jerram <neil@ossau.uklinux.net>
62 * boolean.c (scm_not, scm_boolean_p): Docstring fixes - add
63 texinfo markup and remove trailing newlines.
65 2000-08-17 Michael Livshin <mlivshin@bigfoot.com>
67 this changes the Guile GC to use cards (aka "chunklets").
68 (most of the ideas and some of the code are by Greg Harvey, though
69 the code is probably unrecognizable now. the original chunklet
70 proposal, way back, is by Dale Jordan).
72 * tags.h: (SCM_GCTYPE16, SCM_GCCDR, SCM_GC[8]MARKP,
73 SCM_SETGC[8]MARK, SCM_CLRGC[8]MARK): moved from here into gc.h.
74 some (most) of these are probably going to be deprecated.
76 * gc.h (SCM_MARKEDP): simplified, there are no different mark bit
78 (SCM_GC_CARD_*, SCM_C_BVEC_*): lots of new macros to deal with
79 cards and bvecs (bit-vectors).
81 * gc.c: (scm_default_init_heap_size_*): defined to take cards into
82 account, but keeping more or less the same values as previously.
83 added some simple helper macros.
84 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK): defined to take cards
86 (BVEC_*, scm_mark_space_t, current_mark_space, mark_space_ptr,
87 current_mark_space_offset, mark_space_head, get_bvec,
88 clear_mark_space): new functions and supporting variables, types
89 and macros that implement mark space management.
90 (scm_igc): clear the mark space (all of it) before beginning the
92 (scm_gc_mark): changed the tests for rogue cells, much simplified
93 throughout (no different mark bit locations to worry about now).
94 (scm_mark_locations): don't consider card header cells.
96 (scm_gc_sweep): simplified.
97 (init_heap_seg): changed to take cards into account.
99 2000-08-16 Michael Livshin <mlivshin@bigfoot.com>
101 * stime.c (scm_c_get_internal_run_time): new function, same as
102 scm_get_internal_run_time but returns a long. it's used by the GC
103 for timekeeping, since with scm_get_internal_run_time there is a
104 (extremely theoretical) possibility of consing.
105 (scm_get_internal_run_time): redefined in terms of
106 scm_c_get_internal_run_time.
108 * stime.h: added prototype for scm_c_get_internal_run_time.
110 * gc.c (scm_gc_stats): add more obscure stats, such as: mark time,
111 sweep time, total marked cells, total swept cells, and number of
112 times GC was invoked.
113 (gc_start_stats): renamed from scm_gc_start, made static, taught
114 to init the new stats.
115 (gc_end_stats): renamed from scm_gc_end, made static, taught to
116 calculate the new stats.
117 (scm_igc): don't call gc_start_stats unless we are sure that we
118 are indeed going to collect. also, added some timekeeping between
119 the mark and sweep phases.
120 (scm_gc_sweep): count number of cells we sweep as we go.
122 * gc.h: removed prototypes for scm_gc_{start,end}.
124 2000-08-13 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
126 * alist.c (scm_assq, scm_assv, scm_assoc): Report argument type
127 error for the alist rather than the sublist where the type
128 mismatch is discovered.
130 2000-08-13 Neil Jerram <neil@ossau.uklinux.net>
132 * root.c (s_scm_call_with_dynamic_root): Docstring fix - rogue
135 2000-08-12 Neil Jerram <neil@ossau.uklinux.net>
137 * numbers.c (scm_ash): Docstring fix - missing newlines.

146 * strop.c: Docstring fixes - quotation marks and backslashes
149 * numbers.c (s_scm_logand): Docstring fix - "@end lisp" inserted.
151 2000-08-11 Neil Jerram <neil@ossau.uklinux.net>
153 * macros.c: Remove surplus newlines from end of docstrings.
155 * list.c (scm_list_tail): Add @deffnx line to docstring for
158 * keywords.c: Docstring improvements in conjunction with new
159 reference manual doc on keywords.
161 * error.c (scm_error_scm): Fix texinfo syntax error in
162 docstring. (@code(~S) should be @code{~S}.)
164 * dynl.c: Remove surplus newlines from end of docstrings.
166 2000-08-11 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
168 * eval.c (scm_eval): Backward incompatible change: Now takes an
169 environment specifier as second arg. `eval' hereby becomes R5RS
171 (scm_i_eval_x, scm_i_eval): New functions (replace
173 (scm_eval2, scm_eval_3): Deprecated.
174 (scm_top_level_lookup_closure_var): Deprecated.
176 * eval.h: #include "struct.h".
178 * evalext.c (scm_definedp): Have to work before module system is
181 * modules.h (SCM_MODULEP, SCM_VALIDATE_MODULE,
182 SCM_MODULE_OBARRAY, SCM_MODULE_USES, SCM_MODULE_BINDER,
183 SCM_MODULE_EVAL_CLOSURE): New macros.
184 (scm_module_index_obarray, scm_module_index_uses,

191 (scm_interaction_environment): New primitive.
193 * symbols.c (scm_can_use_top_level_lookup_closure_var): Removed.
194 #include "modules.h".
196 * strports.c (scm_eval_string): Evaluate in
197 scm_interaction_environment ().
199 * script.c (scm_shell): Pass scm_the_root_module () as second arg
202 * load.c (load): Use `scm_selected_module' to compute second arg
203 to new scm_i_eval_x; Don't call it if module system hasn't booted.
204 (scm_read_and_eval_x): Deprecated.
205 #include "modules.h".
207 * debug.c (scm_local_eval): Use scm_i_eval and scm_i_eval_x.
208 (scm_start_stack): Use scm_i_eval.
210 * strports.c: #include "modules.h".
212 * print.c (scm_simple_format): Be case-insensitive for ~A and ~S
215 2000-08-09 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
217 The following changes are intended to ensure that struct instances
218 are freed before their vtables. It's optimized for the most
219 common case, which is freeing of struct instances.
221 * gc.c (scm_gc_mark, scm_gc_sweep): Remove vcell = 1 magic.
222 (scm_structs_to_free): New variable.
223 (scm_gc_sweep): Hook up structs to free on the scm_structs_to_free
226 * struct.h (SCM_STRUCT_GC_CHAIN, SCM_SET_STRUCT_GC_CHAIN): New
228 (scm_structs_to_free, scm_struct_prehistory): Declare.
230 * struct.c (scm_make_struct, scm_make_vtable_vtable): Structs
231 handles are now double cells; Initialize SCM_STRUCT_GC_CHAIN to
233 (scm_struct_gc_init, scm_free_structs): New GC C hooks.
234 (scm_struct_prehistory): Install them.
236 * init.c (scm_boot_guile_1): Call scm_struct_prehistory.
238 2000-08-06 Marius Vollmer <mvo@zagadka.ping.de>
240 * read.c (scm_flush_ws): Include filename in error message when it
243 2000-08-05 Marius Vollmer <mvo@zagadka.ping.de>
245 * iselect.c: Include <unistd.h>. Thanks to Bertrand Petit!
247 2000-08-02 Mikael Djurfeldt <mdj@linnaeus.mit.edu>
249 * struct.c (scm_make_struct_layout, scm_make_struct,
250 scm_make_vtable_vtable): Updated documentation.
252 * print.c (scm_simple_format): Bugfix: Coerce port before using
255 2000-07-31 Gary Houston <ghouston@arglist.com>
257 * net_db.c: declare h_errno only if HAVE_H_ERRNO is not defined
258 (thanks to Richard Kim for the bug report).
260 2000-07-30 Marius Vollmer <mvo@zagadka.ping.de>
262 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
263 scm_assoc_remove_x): Use scm_delq1_x instead of scm_delq_x, since
264 using the latter is pointless.
266 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
268 * gc.c (scm_gc_sweep): Renamed local variable from 'free' to
269 'free_struct_data' to avoid confusion with stdlib's 'free'.
271 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
273 * vectors.c (scm_make_vector): Fix the initialization order of
274 the vector such that the type cell is initialized last.
276 2000-07-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
278 * struct.[ch] (scm_struct_init): Made static. Fixed not to rely
279 on the struct cell to be fully initialized.
281 * struct.c (scm_make_struct, scm_make_vtable_vtable): Fix the
282 initialization order of the struct such that the type cell is
285 2000-07-25 Marius Vollmer <mvo@zagadka.ping.de>
287 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
288 scm_assoc_remove_x): Remove only the first cell with a matching
291 2000-07-24 Marius Vollmer <mvo@zagadka.ping.de>
293 * stime.c (scm_strftime): Recognize a return value of zero from
294 strftime as buffer overflow and take care to detect a valid zero
295 length result regardless. Thanks to David Barts!
297 2000-07-23 Marius Vollmer <mvo@zagadka.ping.de>
299 * alist.c (scm_assq_remove_x, scm_assv_remove_x,
300 scm_assoc_remove_x): Remove all cells whose key is eq, eqv, or
301 equal (respectively) to the argument key, not all cells that are
302 eq, eqv, or equal to the first cell with the argument key. Thanks
305 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
307 * gc.h (SCM_FREE_CELL_CDR, SCM_SET_FREE_CELL_CDR), hooks.c
308 (make_hook), modules.c (OBARRAY, USES, BINDER): Pack and unpack
309 SCM values appropriately.
311 * modules.c (scm_standard_eval_closure): Don't pass an inum to
312 scm_makcclo, but rather a long value.
314 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
316 read.c (scm_lreadrecparen), srcprop.c (scm_set_source_property_x):
317 SCM_SETCDR and SCM_WHASHSET macros don't deliver a return value.
318 Thanks to Han-Wen Nienhuys for the bug report.
320 2000-07-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
322 * root.[ch] (scm_call_catching_errors): Deprecated.
324 * root.c (scm_init_root): Initialize the root smob type using the
325 standard initialization functions.
327 2000-07-17 Marius Vollmer <mvo@zagadka.ping.de>
329 * eval.c (unmemocopy): Don't rely on V being a list of at least
330 one element. Thanks to Bill Schottstaedt!
332 2000-07-15 Michael Livshin <mlivshin@bigfoot.com>
334 * gc.c (scm_done_free): new.
335 expanded comments about scm_done_malloc.
337 * gc.h: added prototype for scm_done_free
339 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
341 * gc.h (scm_take_stdin): Removed.
343 * gc.h (SCM_VALIDATE_CELL): Delegate cell checks to function
344 scm_assert_cell_valid to allow extensions to the checking
345 functionality without need to recompile everything.
347 * gc.[ch] (scm_assert_cell_valid, scm_set_debug_cell_accesses_x):
348 Added as conditionally compiled functions for the case that
349 SCM_DEBUG_CELL_ACCESSES is enabled.
351 * gc.c (debug_cells_p): Added to indicate whether compile-time
352 included cell access debugging is run-time enabled.
354 * gc.[ch] (scm_gc_running_p): Added to indicate that scm_igc is
355 being executed. Intended to be used instead of scm_gc_heap_lock
358 * error.c (scm_error), gdbint.c (SCM_GC_P): Use scm_gc_running_p
359 instead of scm_gc_heap_lock.
361 * gc.c (scm_igc): Set scm_gc_running_p to true while running.
363 * gc.c (scm_mark_locations): Don't mark free cells.
365 * weaks.c (scm_scan_weak_vectors): Use SCM_FREE_CELL_P instead of
368 2000-07-13 Dirk Herrmann <D.Herrmann@tu-bs.de>
370 * gc.c (scm_mark_locations): Minimized some variable scopes and
371 simplified the code a bit.
373 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
375 * gc.h (SCM_SET_FREE_CELL_TYPE, SCM_SET_FREE_CELL_CDR,
376 SCM_FREE_CELL_P, SCM_FREE_CELL_CDR): Added since free cells
377 should not be accessed via SCM_C[AD]R. Further, using dedicated
378 macros to access free cells allows all other cell accessing macros
379 to treat acesses to free cells as errors, thus enabling better
380 error checks for cell accesses. SCM_FREE_CELL_P is supposed to
381 replace SCM_FREEP some time.
383 * gc.h (SCM_NEWCELL, SCM_NEWCELL2), gc.c (map_free_list,
384 free_list_length, scm_check_freelist, scm_debug_newcell,
385 scm_debug_newcell2, freelist_length, scm_gc_for_newcell,
386 scm_gc_mark, scm_gc_sweep, init_heap_seg): Only use the dedicated
387 cell accessors when accessing free cells.
389 2000-07-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
391 * gc.h (SCM_CELL_WORD, SCM_CELL_OBJECT): Treat the referenced
392 object as const in order to make the compiler warn about code like
393 SCM_CELL_WORD (x, n) = y. Instead, SCM_SET_CELL_WORD (x, n, y)
396 (SCM_CELL_WORD_LOC, SCM_CARLOC, SCM_CDRLOC): Return the address
397 as an address to a non-const object, since these macros are used
398 to allow direct write access to objects.
400 2000-07-07 Dirk Herrmann <D.Herrmann@tu-bs.de>
402 * hashtab.c (scm_hash_fn_create_handle_x): Signal an error if the
403 given hash table has no slots.
405 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
407 * gc.c (policy_on_error): Added in order to allow alloc_some_heap
408 to react to malloc failures in a context dependent way.
410 (scm_check_freelist): No need to flush streams before abort().
412 (scm_gc_for_newcell): Try to allocate new memory in three phases:
413 grow heap if preferred, if still no memory available collect
414 garbage, if still no memory available grow heap.
416 (heap_segment_table_size): Added to always reflect the actual
417 size of the heap segment table, because scm_n_heap_segs may differ
418 from the heap segment table size.
420 (alloc_some_heap): In case of malloc failure, react according to
421 the new policy_on_error parameter (either return to caller or
422 abort immediately). Further, keep heap_segment_table_size up to
425 (scm_init_storage): Initialize heap_segment_table_size.
427 2000-07-06 Dirk Herrmann <D.Herrmann@tu-bs.de>
429 * gh.h: Don't include <stdio.h>. Thanks to Han-Wen Nienhuys for
432 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
434 * __scm.h (SCM_OUTOFRANGE, SCM_NALLOC, SCM_HUP_SIGNAL,
435 SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL, SCM_SEGV_SIGNAL,
436 SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL, SCM_SIG_ORD,
437 SCM_ORD_SIG, SCM_NUM_SIGS): Re-introduce these as deprecated
440 * error.c (scm_wta): Re-introduce dispatching for SCM_OUTOFRANGE
441 and SCM_NALLOC, but as a deprecated feature.
443 2000-06-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
445 * debug.c: Added #include fluids.h.
447 * numbers.c (scm_gr_p, scm_leq_p, scm_geq_p): Turned into
448 primitive generics. (Thanks to Nicolas Neuss.)
450 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
452 * gc.c (alloc_some_heap): Use scm_memory_error to indicate a
453 failed attempt to get additional memory from the system.
455 (scm_gc_for_newcell): Changed the control structure to make the
456 behaviour explicit for the case that gc is not able to free any
459 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
461 * __scm.h (SCM_OUTOFRANGE): Removed.
463 * error.c (scm_wta): Removed sick dispatch code for range
464 errors. (More sick dispatches still to be removed.)
466 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
467 scm_hash_fn_remove_x): Eliminate redundant test for if unsigned
468 value is non-negative. Use scm_out_of_range to signal range
471 * hooks.c (make_hook), unif.c (scm_aind): Use scm_out_of_range to
474 * list.c (scm_list_ref, scm_list_set_x, scm_list_cdr_set_x): Fix
475 error reporting (now uses original input parameter to report wrong
476 type argument errors). Use SCM_OUT_OF_RANGE to report range
477 errors and SCM_WRONG_TYPE_ARG to report type errors.
479 * strings.c (scm_substring): Make range checks for negative
480 values explicit (former behaviour relied on an implicit
481 conversion from signed to unsigned). Don't use SCM_ASSERT for
484 * unif.c (scm_aind, scm_transpose_array, scm_bit_set_star_x,
485 scm_bit_count_star): Use scm_out_of_range to signal range
488 * unif.c (scm_transpose_array, scm_bit_position), vectors.c
489 (scm_vector_ref, scm_vector_set_x, scm_vector_move_left_x,
490 scm_vector_move_right_x): Use SCM_ASSERT_RANGE to check ranges.
492 2000-06-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
494 * validate.h (SCM_VALIDATE_INUM_MIN_COPY,
495 SCM_VALIDATE_INUM_MIN_DEF_COPY, SCM_VALIDATE_INUM_RANGE_COPY):
496 Perform all range checks based on the input value. The former way
497 of using the value that is assigned to the target variable fails
498 if the assignment to the target variable itself can change the
499 value because of type conversion.
501 (SCM_ASSERT_RANGE): Use scm_out_of_range to signal range errors.
503 2000-06-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
505 * gc.c (scm_gc_for_newcell): Behave gracefully also if scm_igc
506 doesn't yield any new cells. In theory this could happen if all
507 cells allocated with NEWCELL are either in use or conservatively
508 marked and all cluster spine cells are conservatively marked.
511 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
513 * __scm.h (SCM_NALLOC): Removed.
515 * error.c (scm_wta): Removed sick dispatch code for memory
516 errors. (More sick dispatches still to be removed.)
518 * numbers.c (scm_mkbig, scm_adjbig), ports.c (scm_make_port_type),
519 random.c (scm_i_copy_rstate, scm_c_make_rstate), smob.c
520 (scm_make_smob_type), srcprop.c (scm_make_srcprops), vectors.c
521 (scm_vector_set_length_x): Now using scm_memory_error to signal
524 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
526 * __scm.h: Removed some commented code and fixed some comments.
528 (SCM_HUP_SIGNAL, SCM_INT_SIGNAL, SCM_FPE_SIGNAL, SCM_BUS_SIGNAL,
529 SCM_SEGV_SIGNAL, SCM_ALRM_SIGNAL, SCM_GC_SIGNAL, SCM_TICK_SIGNAL,
530 SCM_SIG_ORD, SCM_ORD_SIG, SCM_NUM_SIGS): Removed.
532 * async.c: Removed some commented code.
534 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
536 * gc.c (scm_gc_mark, scm_gc_sweep, scm_must_malloc,
537 scm_must_realloc, scm_must_free, alloc_some_heap): Use the
538 appropriate error signalling function.
540 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
542 * root.h (scm_first_type): Removed.
544 2000-06-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
546 * gc.c (MIN_GC_YIELD): Removed.
548 2000-06-28 Michael Livshin <mlivshin@bigfoot.com>
550 * gc.c (scm_gc_for_newcell): don't try to do GC if it's blocked,
553 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
555 * async.c (scm_gc_async, scm_gc_vcell, scm_sys_gc_async_thunk):
558 (scm_init_async): Moved initialization for scm_gc_async and
559 scm_gc_vcell to gc.c. Moved initialization of scm_asyncs here
562 * async.h (scm_gc_async): Not globally visible any more.
564 * gc.c (scm_gc_stats): Made callable even from within regions
567 (scm_gc_end): Eliminate the hardcoding of the marking of the
568 scm_gc_async from the gc core.
570 (scm_init_storage): Don't initialize the scm_asyncs list here.
571 This is now done in asyncs.c.
573 (scm_gc_vcell): Moved here from async.c.
575 (gc_async): Renamed from scm_gc_async, moved here from async.c
578 (gc_async_thunk): Renamed from scm_sys_gc_async_thunk and moved
581 (mark_gc_async): New hook function for scm_after_gc_c_hook.
583 (scm_init_gc): Added initialization of scm_gc_vcell and
584 gc_async. Further, add mark_gc_async to scm_after_gc_c_hook.
586 * init.c (scm_boot_guile_1): scm_init_gc requires asyncs to be
589 2000-06-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
591 * gc.c (scm_igc): Removed commented code that once was intended
592 to unprotect struct types with no instances.
594 * root.h (scm_type_obj_list): Removed.
596 2000-06-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
598 * async.c (scm_init_async): Switch to standard way of smob
601 2000-06-21 Michael Livshin <mlivshin@bigfoot.com>
603 * guile-doc-snarf.in: use cut instead of sed, that's much much
604 faster. also, don't call basename more than needed. and, to gain
605 a couple of microseconds more, don't call cat needlessly. (thanks
608 2000-06-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
610 * guile-snarf.awk.in, guile-snarf.in, snarf.h: Rename SCM__I to
611 SCM_SNARF_INIT_START, SCM__D to SCM_SNARF_DOC_START, SCM__S to
612 SCM_SNARF_DOCSTRING_START and SCM__E to SCM_SNARF_DOCSTRING_END.
614 2000-06-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
616 * eval.c, eval.h (scm_top_level_lookup_closure_var): Added.
617 #include "libguile/fluids.h".
619 * eval.h (SCM_TOP_LEVEL_LOOKUP_CLOSURE): New macro which replaces
620 SCM_CDR (scm_top_level_lookup_closure_var) everywhere.
622 * root.h (scm_top_level_lookup_closure_var,
623 scm_system_transformer): Removed. (It's no sense in having the
624 *variable* be a "fluid".)
626 * root.c (mark_root): Removed marking of
627 s->top_level_lookup_closure_var and s->system_transformer.
629 * modules.c (scm_selected_module): the_module is now a fluid.
631 2000-06-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
633 * gc.h, tags.h: Be kind to compilers which must see hash signs in
634 column 0. (Thanks to Ian Grant.)
636 * numbers.h: Put #ifdef HAVE_LONG_LONGS around declarations using
637 the long_long type. (Thanks to Bernard Urban.)
639 2000-06-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
641 * gc.c, gc.h (scm_default_init_heap_size_1,
642 scm_default_min_yield_1, scm_default_init_heap_size_2,
643 scm_default_min_yield_2, scm_default_max_segment_size): New global
644 variables. Can be customized by the application before booting
645 Guile. (We might want to be able to control these parameters
646 dynamically through the "options interface" in the future, but
647 note that that is additional functionality. Here we're giving
648 default values which the environment variables can override.)
650 * list.c (scm_cons_star): Updated comment.
652 * smob.h: Changed comments for scm_make_smob_type and
653 scm_make_smob_type_mfpe, warning that the latter might be
654 deprecated in a future release.
656 2000-06-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
658 * list.[ch] (scm_cons_star/cons*): Renamed from
661 * list.[ch] (scm_list_star/list*): Provided as a deprecated alias
662 for scm_cons_star/cons*.
664 * gc.c (scm_protect_object): Updated comment.
666 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX): Removed.
668 * tags.h (SCM_UNPACK_CAR, SCM_NDOUBLE_CELLP): Removed.
670 2000-06-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
672 * init.c, init.h (scm_initialized_p): Renamed from `initialized'
675 * gdbint.c (gdb_print): Print warning instead of calling scm_write
676 if Guile isn't yet initialized.
678 * print.c (scm_current_pstate, scm_make_print_state): Simplified
679 tests, using the assumption that Guile has been initialized.
681 Sun Jun 18 14:45:21 2000 Greg J. Badros <gjb@cs.washington.edu>
683 * print.c (s_scm_current_pstate): Do not segfault when the
684 print_state_pool is unitialized in `current-pstate', and better
685 verify its state before altering it in scm_make_print_state().
687 2000-06-18 Michael Livshin <mlivshin@bigfoot.com>
689 * scmsigs.c (s_scm_sigaction): guard the SIGIOT case with an
690 #ifdef -- it's missing on at least one platform. (thanks to
693 2000-06-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
695 * list.c (list*): Added documentation from common-list.scm.
697 2000-06-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
699 * gc.c (scm_unprotect_object): The reference count is guaranteed
700 to be a positive number.
702 2000-06-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
704 * eval.c: Updated comment above scm_map.
706 2000-06-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
708 * gc.c (scm_protect_object): Avoid looking up the object handle
710 (scm_unprotect_object): Abort if scm_unprotect_object is called on
711 an unprotected object.
713 2000-06-14 Michael Livshin <mlivshin@bigfoot.com>
715 * gc.c (scm_unprotect_object): fix a nasty typo bug (thanks to
718 2000-06-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
720 * socket.c (scm_getsockopt): Changed type for `optlen' from int to
722 (scm_accept, scm_getsockname, scm_getpeername, scm_recvfrom):
723 Ditto for `tmp_size'.
724 (scm_addr_buffer_size): Changed type from int to size_t.
726 * random.c: #include <string.h>. (Needed by memcpy.)
728 * guile-snarf.awk.in: Replace the dot_doc_file arg with "-",
729 indicating stdin, instead of "" and don't reset ARGC. This is a
730 workaround for `nawk' in AIX 4.3 on RS6000 but, as far as I know,
731 it is correct, and perhaps even better.
733 2000-06-14 Gary Houston <ghouston@arglist.com>
735 * scmsigs.c (scm_init_scmsigs): if HAVE_SIGINTERRUPT is not
736 defined, add SA_RESTART to the sigaction flags correctly
737 (thanks to Dale P. Smith).
739 2000-06-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
741 * strings.c: #include <string.h>. (Thanks to Bill Schottstaedt.)
743 * net_db.c (scm_resolv_error): Only use macro NETDB_INTERNAL if
744 defined. It isn't on sgi irix 5.3. (Thanks to Bill Schottstaedt.)
746 * Makefile.am (.c.doc): Pipe output (the .x contents) to /dev/null.
748 2000-06-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
750 * fports.c (scm_setvbuf): Use `free' instead of `scm_must_free'
751 since read and write buffers are allocated by `malloc'.
753 * Makefile.am: Removed old test code.
755 * gh_test_c.c, gh_test_repl.c: Removed.
757 2000-06-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
759 * iselect.c (SCM_NLONGBITS): Add workaround for the Sun 4.2
762 * inet_aton.c (inet_aton): Cast init value for `cp'.
764 * ramap.c (s_scm_array_fill_x): Cast `ve' properly in case
767 * symbols.c (scm_intern_obarray_soft,
768 scm_sysintern0_no_module_lookup): Cast `name' to unsigned char ptr
769 in calls to scm_strhash.
771 * strports.c (st_resize_port): Substituted SCM_UCHARS for
773 (st_write): Cast argument to strncpy to char ptr.
774 (scm_mkstrport): Substituted SCM_ROUCHARS for SCM_ROCHARS.
775 (scm_strport_to_string): Cast argument to scm_makfromstr to char
778 * ports.c (scm_ungetc): Cast value to unsigned char ptr before
779 storing in putback_buf.
780 (scm_unread_string): Substituted SCM_ROCHARS for SCM_ROUCHARS.
782 * ioext.c (s_scm_read_line): Cast result of call to
783 scm_do_read_line to unsigned char ptr.
785 * gdbint.c (SEND_STRING): Cast argument to char pointer.
787 * fports.c (fport_flush): Declare `ptr' as unsigned char (was
790 * Makefile.am (DOT_DOC_FILES): List doc-files explicitly. (We
791 shouldn't use Make rules which aren't supported by most Make
793 (OMIT_DEPENDENCIES): Defined to "libguile.h ltdl.h". (We don't
794 want these dependencies recorded, since they would get bogus
795 relative paths; libguile.h is only used in gh.h and guile.c.)
796 (EXTRA_DOT_X_FILES, EXTRA_DOT_DOC_FILES): New variables.
797 (guile-procedures.txt): Depend on EXTRA_DOT_DOC_FILES.
798 (modinclude_HEADERS): Removed kw.h.
800 * guile-snarf.in: Change regexp "^SCM__I" --> "^ *SCM__I".
801 (The preprocessor might insert spaces before the identifier.)
803 * snarf.h (SCM_SNARF_HERE, SCM_SNARF_INIT, SCM_SNARF_DOCS):
804 Renamed from SCM_HERE, SCM_INIT, SCM_DOCS.
806 * smob.h (scm_smobfuns): Removed deprecated type.
808 * smob.c, smob.h (scm_newsmob): Removed deprecated function.
809 (Replaced by `scm_make_smob_type'.)
811 * keywords.c (scm_tc16_kw): Removed deprecated type.
812 (Replaced by scm_tc16_keyword.)
814 * kw.h: Removed deprecated header file.
816 * evalext.c (serial-map): Removed deprected alias for scm_map.
817 (Has been replaced by `map-in-order'.)
819 * ramap.c (serial-array-copy!, serial-array-map!): Removed
820 depracted aliases. (Replaced by `array-copy-in-order!' and
821 `array-map-in-order'.)
823 2000-06-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
825 * gc.h (SCM_VALIDATE_CELL): Rewritten.
826 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
827 SCM_SET_CELL_OBJECT): Use new version of SCM_VALIDATE_CELL.
828 (Thanks to Han-Wen Nienhuys.)
830 2000-06-10 Michael Livshin <mlivshin@bigfoot.com>
832 * guile-doc-snarf.in: don't pipe the CPP output right into sed --
833 write it to the temp file first and check the CPP return code.
834 (I introduced this bug earlier, and this probably caused people
835 with non-GNU C preprocessors to get empty *.x files and not to
836 have the build fail right away...).
838 * scmsigs.c (s_scm_sigaction): guard the SIGSYS case with an ifdef
839 -- at least my libc5-based Linux system doesn't define SIGSYS.
841 2000-06-08 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
843 * snarf.h, guile-snarf.awk.in, guile-snarf.in: Replaced snarf
844 markers with identifiers (SCM__I, SCM__D, SCM__S, SCM__E).
845 (Thanks to Bernard Urban.)
847 2000-06-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
849 * modules.c (scm_system_module_env_p): Fixed detection of system
852 2000-06-06 Marius Vollmer <mvo@zagadka.ping.de>
854 * scmsigs.c (scm_sigaction): Silently ignore setting handlers for
855 `program error signals' because they can't currently be handled by
858 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
860 * procs.h (SCM_SET_SUBRF): Added.
862 * procs.c (scm_make_subr_opt): Don't assign to SCM_SUBRF, use
863 SCM_SET_SUBRF instead. Thanks to Bernard Urban for the bug
866 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
868 * gc.h (SCM_CARLOC, SCM_CDRLOC): Don't take the address of a SCM
871 * sort.c (scm_sorted_p, scm_merge, scm_merge_list_x,
872 scm_merge_list_step): Don't take the address of SCM_CAR. Use
873 SCM_CARLOC instead. Thanks to Bernard Urban for the bug report.
875 2000-06-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
877 * boolean.h (SCM_TRUE_P): Removed, as people might use it as a
878 replacement for !SCM_FALSEP.
880 * backtrace.c (display_error_body), boolean.h (SCM_BOOLP), gc.c
881 (scm_unhash_name), gh_data.c (gh_module_lookup), load.c
882 (scm_primitive_load), print.c (scm_simple_format), procs.c
883 (scm_procedure_documentation), procs.h (SCM_TOP_LEVEL), ramap.c
884 (scm_array_fill_int), scmsigs.c (scm_sigaction), stacks.c
885 (narrow_stack, scm_make_stack, scm_stack_id), symbols.c
886 (scm_string_to_obarray_symbol), throw.c (scm_catch,
887 scm_lazy_catch, scm_ithrow), unif.c (scm_make_uve, scm_array_p,
888 scm_array_set_x, scm_bit_set_star_x, scm_bit_count_star),
889 validate.h (SCM_VALIDATE_BOOL_COPY, SCM_VALIDATE_PROC): Replace
890 uses of SCM_TRUE_P (x) with SCM_EQ_P (x, SCM_BOOL_T).
892 2000-06-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
894 * eval.c (scm_badformalsp): New static function.
895 (SCM_CEVAL): Check arguments for procedure-with-setter closures.
896 (Thanks to Keisuke Nishida.)
898 The major reason for Guile's slow loading speed has been the fact
899 that a chain of Scheme level procedures has been evaluated for
900 every top-level symbol lookup during the first pass through the
903 The following is a kludge which I suggested four years ago, and
904 which I've repeatedly suggested since. Personally, I've never
905 been bothered by Guile's slow loading speed, so I thought I would
906 let someone else do it...
908 But since the new environments will be included first in
909 Guile-1.5, I thought it would make people happy to get the kludge
912 * modules.c: Added #include "libguile/vectors.h";
913 Added #include "libguile/hashtab.h";
914 Added #include "libguile/struct.h";
915 Added #include "libguile/variable.h";
916 Capture Scheme level `module-make-local-var!' to be used in the
917 standard eval closure.
918 (scm_standard_eval_closure): New primitive.
920 * modules.h (scm_standard_eval_closure): Declare.
922 * eval.c (scm_lookupcar): Test for !SCM_CONSP (SCM_CAR (env))
923 instead of SCM_TRUE (scm_procedurep (SCM_CAR (env))).
925 * symbols.c (scm_sym2vcell): Bypass dispatch in the evaluator for
926 standard eval closures.
928 * variable.c: Code layout fixes.
930 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
932 * Makefile.am: Added LIBS line to libpath which accidentally
933 disappeared in the change of 2000-06-01.
934 (Thanks to Dale P. Smith.)
936 2000-06-03 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
938 * scmsigs.c (scm_segfault): Removed. (Was probably added by
939 mistake since it is not mentioned in ChangeLog.)
941 * gc.h (SCM_VALIDATE_CELL): Cast result to (void) in order to
942 avoid compiler warnings in gcc. (Does this work for other
945 2000-06-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
947 * gc.h (SCM_VALIDATE_CELL): Don't "use" the value returned by
949 (SCM_CARLOC, SCM_CDRLOC): Define directly instead of using
950 SCM_CELL_OBJECT_0 and SCM_CELL_OBJECT_1. It's not correct to take
951 the address of these expressions since they use SCM_VALIDATE_CELL.
952 (Thanks to Bernard Urban.)
954 * dynl.c: Changed #include <ltdl.h> --> #include
955 "libltdl/ltdl.h". (Thanks to Bill Schottstaedt.)
957 2000-06-01 Craig Brozefsky <craig@red-bean.com>
959 * Makefile.am: libguile_la_LDFLAGS gets -version-info args
960 from GUILE-VERSION definition of LIBGUILE version. Added to
961 libpath.h definitions for guileversion and libguileversion which
962 both get their values from GUILE-VERSION definition.
964 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
966 * numbers.h (SCM_BIGP): Don't use SCM_SMOB_PREDICATE in header
967 file: Code using numbers should not be required to include
970 2000-05-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
972 * coop-threads.c.cygnus, coop-threads.h.cygnus, fsu-pthreads.h,
973 mit-pthreads.c, mit-pthreads.h: Deleted.
975 * Makefile.am (EXTRA_DIST), scmsigs.c, threads.[ch]: Drop
976 references to deleted files and fsu/mit thread support in
979 2000-05-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
981 * hooks.c (symbol_name, scm_create_hook): Restored the original
982 behaviour of scm_create_hook. Changing it was bad as Carl
983 R. Witty has pointed out.
985 * gc.c (scm_init_gc): We can still rely on scm_create_hook to
988 2000-05-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
990 * gc.c (scm_init_gc): Protect scm_after_gc_hook, since this will
991 soon not be done by scm_create_hook any longer.
993 * hooks.c (make_hook, print_hook, scm_create_hook,
994 scm_make_hook_with_name, scm_make_hook), hooks.h (SCM_HOOK_NAME,
995 SCM_HOOK_PROCEDURES, SCM_SET_HOOK_PROCEDURES,
996 scm_make_hook_with_name), init.c (scm_boot_guile_1): Hooks no
997 longer have names. As an intermediate solution, the name
998 predicate is emulated via object properties, but use of this
999 feature is deprecated.
1001 * hooks.h (scm_free_hook): Removed, as it is never defined.
1003 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1005 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_FIXABLE):
1006 Un-deprecated since otherwise user code can't determine whether a
1007 number fits into an inum any longer. The names should be changed
1010 * numbers.c (scm_big2inum): Eliminated use of SCM_UNEGFIXABLE.
1012 * tags.h (SCM_UNPACK_CAR): Deprecated.
1014 2000-05-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1016 * filesys.h (SCM_OPDIRP), fluids.h (SCM_FLUIDP, SCM_FLUID_NUM),
1017 fports.h (SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP), hooks.h
1018 (SCM_HOOK_ARITY), keywords.h (SCM_KEYWORDP, SCM_KEYWORDSYM),
1019 numbers.h (SCM_NUMP, SCM_BIGSIGN, SCM_BDIGITS, SCM_NUMDIGS):
1020 Replace SCM_UNPACK_CAR appropriately. Don't access cells via
1021 SCM_{SET}?C[AD]R unless they are known to be cons cells.
1023 * gc.c (scm_heap_seg_data_t, scm_mark_locations, scm_cellp,
1024 init_heap_seg): Remove unused struct member variable 'valid'.
1026 2000-05-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
1028 * fports.c (fport_write), ports.c (scm_markstream, scm_port_mode,
1029 scm_print_port_mode), ports.h (SCM_OPPORTP, SCM_OPINPORTP,
1030 SCM_OPOUTPORTP, SCM_INPUT_PORT_P, SCM_OUTPUT_PORT_P, SCM_OPENP),
1031 procs.h (SCM_CLOSCAR), unif.h (SCM_ARRAY_NDIM, SCM_ARRAY_CONTP),
1032 variable.h (SCM_VARIABLEP): Replace SCM_UNPACK_CAR
1035 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1037 * gc.c (free_list_length), hash.c (scm_hasher), macros.c
1038 (scm_macro_type), objects.c (scm_class_of), options.c
1039 (scm_options), print.c (scm_iprin1), strports.c (st_seek), throw.c
1040 (SCM_LAZY_CATCH_P): Replace SCM_UNPACK_CAR appropriately.
1042 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1044 * eval.c (scm_macroexp, SCM_CEVAL, scm_force), tags.h: Replace
1045 SCM_UNPACK_CAR with SCM_CELL_TYPE or SCM_CELL_WORD_0.
1047 * eval.c (scm_force): Add documentation.
1049 * eval.c (scm_force, scm_cons_source): Don't access cells via
1050 SCM_{SET}?C[AD]R unless they are known to be cons cells.
1052 2000-05-23 Dirk Herrmann <D.Herrmann@tu-bs.de>
1054 * strings.h (SCM_NSTRINGP, SCM_NRWSTRINGP), tags.h
1055 (SCM_NDOUBLE_CELLP), vectors.h (SCM_NVECTORP): Deprecated.
1057 * gc.c (scm_igc), gc.h (SCM_PTR_MASK, SCM_PTR_LT): Removed #ifdef
1058 nosve #endif conditionally compiled code.
1060 2000-05-23 Michael Livshin <mlivshin@bigfoot.com>
1062 * gc.c (scm_heap_seg_data_t): fixed comment for the `span' member.
1064 2000-05-22 Michael Livshin <mlivshin@bigfoot.com>
1066 * guile-doc-snarf.in: put the preprocessed file through sed to
1067 trim all lines to 1024 chars. I hope it doesn't break anybody's
1068 sed. we'll see. (note: this is lossy trimming, i.e. the spill
1069 isn't wrapped around but actually chopped off. this seemed to me
1070 safe because the current snarfer doesn't understand multi-line
1071 cookies anyway. in the long term, it would be nice not to depend
1072 on AWK for anything.)
1074 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): reverted
1075 the previous change to this macros, after deciding to torture the
1078 2000-05-21 Michael Livshin <mlivshin@bigfoot.com>
1080 * gc.h (SCM_[SET_]CELL_{WORD,OBJECT}, SCM_VALIDATE_CELL): brought
1081 the yucky, ugly and nasty conditional compilation back. sorry,
1082 but it was either that or requiring GAWK to build Guile.
1083 (lots of places): removed the code that implemented the old GC
1086 * init.c (scm_boot_guile_1): removed the code conditioned on
1087 !GUILE_NEW_GC_SCHEME.
1089 * __scm.h: (GUILE_NEW_GC_SCHEME): removed.
1091 * gc.c (scm_protect_object, scm_unprotect_object): change the
1092 implementation to more efficient (at least in the time complexity
1093 sense). the calls should now also be thread-safe -- I suspect
1094 that people expect them to be. (thanks to Han-Wen Nienhuys)
1095 (lots of places): removed the code that implemented the old GC
1098 * hashtab.c (scm_hash_fn_create_handle_x): add missing
1099 SCM_REALLOW_INTS before return. I really wonder about the
1100 possible interactions between hashtables, threads & GC. it
1101 doesn't look healthy at all.
1103 2000-05-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
1105 * unif.c (scm_bit_count): Fixed the parameter checks. Thanks to
1108 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1110 * __scm.h (SCM_DEBUG_CELL_ACCESSES), gc.h (SCM_): Added as a new
1111 debug option to verify all accesses to cells actually access
1112 objects on the heap.
1114 * gc.h (SCM_VALIDATE_CELL): Added. Only performs validation if
1115 SCM_DEBUG_CELL_ACCESSES is set to 1.
1117 (SCM_CELL_WORD, SCM_CELL_OBJECT, SCM_SET_CELL_WORD,
1118 SCM_SET_CELL_OBJECT): Use SCM_VALIDATE_CELL to check every cell
1121 2000-05-19 Dirk Herrmann <D.Herrmann@tu-bs.de>
1123 * gh_data.c (gh_scm2chars, gh_scm2shorts, gh_scm2longs,
1124 gh_scm2floats, gh_scm2doubles): Change !SCM_NIMP to SCM_IMP.
1126 * gc.c (scm_cellp): Fixed and simplified.
1128 * throw.c (JBJMPBUF, SETJBJMPBUF, SCM_JBDFRAME, SCM_SETJBDFRAME,
1129 make_jmpbuf, scm_init_throw): Now using double cells to represent
1130 jump buffers when using debug extensions.
1134 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1136 * gh.h gh_data.c gh_funcs.c (gh_new_procedure*, gh_chars2byvect,

1138 gh_doubles2dvect, gh_doubles2scm, gh_define, gh_lookup,
1139 gh_module_lookup): Accept const pointers as parameters.
1141 * gh.h gh_data.c (gh_int2scmb): Deprecated.
1143 2000-05-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
1145 * __scm.h (SCM_DEBUG_REST_ARGUMENT): Renamed from
1146 SCM_DEBUG_REST_ARGUMENTS in order to clarify that we don't test
1147 the actual arguments in the list, but rather the rest argument as
1148 a list of arguments.
1150 * validate.h (SCM_VALIDATE_REST_ARGUMENT): Added.
1152 * async.c (scm_noop), eval.c (scm_map, scm_for_each), list.c
1153 (scm_list_star, scm_append, scm_append_x), ports.c
1154 (scm_close_all_ports_except), ramap.c (scm_array_map_x,
1155 scm_array_for_each), regex-posix.c (scm_make_regexp), stacks.c
1156 (scm_make_stack), strings.c (scm_string_append), struct.c
1157 (scm_make_struct, scm_make_vtable_vtable): Validate rest arguments.
1159 * dynl.c (DYNL_GLOBAL, sysdep_dynl_link, kw_global, sym_global,
1160 scm_dynamic_link, scm_init_dynamic_linking), dynl.h
1161 (scm_dynamic_link): Removed possibility to pass flags to
1162 scm_dynamic_link, as it had no effect anyway.
1164 * filesys.c (scm_fcntl): Made single optional rest argument into
1165 a standard optional argument.
1167 * hooks.c (scm_run_hook): A list of rest arguments is never
1170 * list.c (scm_append, scm_append_x), stacks.c (scm_make_stack),
1171 strings.c (scm_string_append): Don't perform half-hearted checks
1172 to see whether the rest argument forms a proper list any more, use
1173 SCM_VALIDATE_REST_ARGUMENTS instead.
1175 * ports.c (scm_close_all_ports_except): Accept empty list of rest
1178 * posix.c (scm_convert_exec_args), print.c (scm_simple_format):
1179 Simplify verification of rest argument.
1181 * stacks.c (scm_make_stack), stacks.h (scm_make_stack), throw.c
1182 (ss_handler, handler_message): Make first mandatory rest argument
1183 of scm_make_stack into a standard mandatory argument.
1185 * unif.c (scm_transpose_array, scm_enclose_array,
1186 scm_array_in_bounds_p), unif.h (scm_transpose_array,
1187 scm_enclose_array, scm_array_in_bounds_p): Make first mandatory
1188 rest argument into a standard mandatory argument.
1190 2000-05-17 Dirk Herrmann <D.Herrmann@tu-bs.de>
1192 * __scm.h: Added SCM_DEBUG as default debug option. (Thanks to
1193 Keisuke Nishida for the suggestion.) Added debug option
1194 SCM_DEBUG_REST_ARGUMENTS.
1196 * eval.c (scm_map, scm_for_each): Make sure all lists have the
1197 same length. Also, removed redundant parameter checks.
1199 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1201 * Makefile.am: Let 'make clean' remove *.x and *.doc files.
1203 * __scm.h: Improved explanation of giving options to make.
1205 * __scm.h (SCM_DEBUG_TYPING_STRICTNESS), tags.h
1206 (SCM_STRICT_TYPING, SCM_DEBUG_TYPING_STRICTNESS): Renamed
1207 SCM_STRICT_TYPING to SCM_DEBUG_TYPING_STRICTNESS and moved the
1208 corresponding declaration and comment to __scm.h.
1210 * _scm.h (errno), gc.h (SCM_CELLPTR, SCM_PTR_LT), numbers.c
1211 (scm_remainder, scm_modulo), numbers.h (SCM_SRS, SCM_MAKINUM,
1212 SCM_INUM): Removed conditionally compiled code for Turbo C.
1214 * gdbint.c (gdb_maybe_valid_type_p): Eliminated call to scm_tag.
1215 That check can be assumed to be redundant except for very rare
1216 conditions that actually indicate broken heap data.
1218 2000-05-16 Dirk Herrmann <D.Herrmann@tu-bs.de>
1220 * numbers.c (scm_logcount, scm_integer_length): Reordered
1223 2000-05-15 Gary Houston <ghouston@arglist.com>
1225 * stime.c (scm_strftime): don't reset TZ if zone is an empty
1226 string. append a "0" to the zone for TZ.
1228 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
1230 * numbers.c (scm_logbit_p, scm_bit_extract): Reordered dispatch
1233 (scm_bit_extract): Fixed handling of bignums.
1235 2000-05-15 Dirk Herrmann <D.Herrmann@tu-bs.de>
1237 * async.c (scm_sys_gc_async_thunk), chars.h (SCM_ICHRP, SCM_ICHR,
1238 SCM_MAKICHR), continuations.h (SCM_SETJMPBUF), error.c

1241 keywords.c (scm_tc16_kw, scm_init_keywords), ports.h (SCM_CRDY,
1242 SCM_INPORTP, SCM_OUTPORTP), ramap.c ('serial-array-copy!,
1243 'serial-array-map!), smob.c (scm_newsmob), smob.h (scm_smobfuns,
1244 scm_newsmob), tag.c (scm_tag), tag.h (scm_tag), tags.h
1245 (scm_tc16_flo, scm_tc_flo, scm_tc_dblr, scm_tc_dblc): Wrapped
1246 deprecated code between #if (SCM_DEBUG_DEPRECATED == 0) #endif.
1248 * fports.c (scm_fport_buffer_add), ports.c (scm_input_port_p,
1249 scm_output_port_p), print.c (scm_get_print_state), validate.h
1250 (SCM_VALIDATE_CHAR): Replace use of deprecated macros
1251 SCM_INPORTP, SCM_OUTPORTP, SCM_ICHRP by SCM_INPUT_PORT_P,
1252 SCM_OUTPUT_PORT_P, SCM_CHARP, respectively.
1254 2000-05-14 Gary Houston <ghouston@arglist.com>
1256 * stime.c (scm_strftime): if HAVE_TM_ZONE is not defined, hack the
1257 TZ environment variable so that the %Z format returns the zone
1258 from the input vector instead of the system default.
1260 from Keisuke Nishida:
1261 * fports.c (scm_setvbuf): minor docstring fix.
1262 * ports.h (scm_generic_fgets): obsolete prototype deleted.
1264 2000-05-11 Dirk Herrmann <D.Herrmann@tu-bs.de>
1266 * __scm.h: Added new section for debugging options.
1268 (SCM_DEBUG_DEPRECATED): If 1, no deprecated code is included to
1269 help developers to get rid of references to deprecated code.
1271 * numbers.[ch] (SCM_POSFIXABLE, SCM_NEGFIXABLE, SCM_UNEGFIXABLE,
1272 SCM_FIXABLE, SCM_FLOBUFLEN): These macros are no longer provided
1273 as part of the interface and are marked as deprecated in the
1276 * numbers.c (scm_make_real, scm_make_complex): Inlined the
1277 corresponding macros SCM_NEWREAL and SCM_NEWCOMPLEX,
1280 * numbers.h (SCM_NEWREAL, SCM_NEWCOMPLEX, SCM_INEXP, SCM_CPLXP,
1281 SCM_REAL, SCM_IMAG, SCM_REALPART, scm_makdbl, SCM_SINGP,
1282 SCM_NO_BIGDIG, SCM_NUM2DBL, scm_dblproc): Deprecated.
1284 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1286 * gc.h (scm_cell, SCM_CELL_WORD, SCM_CELL_OBJECT,
1287 SCM_SET_CELL_WORD, SCM_SET_CELL_OBJECT): Scheme cells now consist
1288 of two scm_bits_t values instead of two SCM values, because it is
1289 legal for cell entries to hold values that are not scheme objects.
1291 (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR):
1292 Use SCM_SETC[AD]R to modify contents of pairs.
1294 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1296 * numbers.c (IS_INF, isfinite): Added FIXME comment.
1298 (scm_abs, scm_magnitude): Make these two independent of each
1299 other. scm_abs now reports an error if given a complex argument.
1301 (scm_istr2flo, scm_integer_p). Use SCM_REAL_VALUE instead of
1302 SCM_REALPART if the object is known to be real.
1304 (scm_init_numbers): No need to use SCM_NEWREAL macro for speed
1307 * numbers.h (SCM_SINGP): Set to 0 instead of SCM_BOOL_F.
1309 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1311 * eq.c (scm_eqv_p): Separate handling of real and complex
1312 values. Remove #ifdef SCM_BIGDIG #endif test.
1314 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_scm2floats,
1315 gh_scm2doubles), hash.c (scm_hasher), ramap.c (scm_array_fill_int,
1316 ramap_rp, scm_array_map_x), random.c (vector_scale,
1317 vector_sum_squares), unif.c (scm_make_uve, scm_array_p,
1318 scm_array_set_x): Use SCM_REAL_VALUE instead of SCM_REALPART if
1319 the object is known to be real. Use SCM_COMPLEXP instead of
1320 deprecated SCM_CPLXP. Use SCM_INEXACTP instead of deprecated
1323 2000-05-10 Dirk Herrmann <D.Herrmann@tu-bs.de>
1325 * numbers.c: No need to include unif.h.
1327 (IS_INF): Returned to old test for now: x == x + 1 will not work
1328 for large numbers due to rounding errors.
1329 Thanks to Kalle Olavi Niemitalo.
1331 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1333 * numbers.c (scm_divbigdig): Removed outdated comment.
1335 (scm_number_to_string, scm_string_to_number, scm_number_p,
1336 scm_real_p, scm_integer_p, scm_inexact_p, scm_gr_p, scm_leq_p,
1337 scm_geq_p, scm_make_rectangular, scm_make_polar,
1338 scm_inexact_to_exact): Added comments.
1340 (add1, scm_init_numbers): Removed add1.
1342 2000-05-09 Dirk Herrmann <D.Herrmann@tu-bs.de>
1344 * numbers.c (IS_INF): The new test is x == x + 1. The old test
1345 x == x/2 did not work for zero values. Thanks to Han-Wen Nienhuys
1348 (scm_number_to_string, scm_sum, scm_difference, scm_two_doubles,
1349 scm_num2long, scm_num2long_long, scm_num2ulong): Reordered
1352 2000-05-09 Marius Vollmer <mvo@zagadka.ping.de>
1354 * scmsigs.c (take_signal): Execute SCM_ASYNC_TICK for SIGSEGV,
1355 SIGILL and SIGBUS signals. These signals are not continuable and
1356 must be handled for real right away.
1358 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1360 * numbers.c (scm_zero_p, scm_positive_p, scm_negative_p,
1361 scm_real_part, scm_imag_part, scm_magnitude,
1362 scm_inexact_to_exact): Reordered dispatch sequence.
1364 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1366 * feature.c: No need to include "libguile/smob.h"
1368 (scm_loc_features, features, scm_add_feature, scm_init_feature):
1369 Removed variable 'scm_loc_features' as a pointer to the SCM value
1370 holding the features list. Using variable 'features' instead,
1371 which holds the interned pair. Thus, SCM_SETCDR can be used
1372 instead of pointer trickery.
1374 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1376 * alist.c (scm_acons): Use SCM{_SET}?_CELL_OBJECT as long as a
1377 cell is not known to be a valid pair.
1379 2000-05-08 Dirk Herrmann <D.Herrmann@tu-bs.de>
1381 * eval.c (ASRTSYNTAX, scm_m_body, scm_m_letrec1): Removed
1382 ASRTSYNTAX. Using SCM_ASSYNT instead.
1384 (scm_m_body): Don't create a redundant cons cell.
1386 (scm_m_do): Removed redundant test 'bodycheck'.
1388 (bodycheck): Removed.
1390 * stacks.c (stack_depth, read_frame, read_frames): Removed
1391 redundant calculation of size, minimized some variable scopes.
1393 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1395 * pairs.c (scm_cons, scm_cons2): Use SCM{_SET}?_CELL_OBJECT as
1396 long as a cell is not known to be a valid pair.
1398 (scm_pair_p): Eliminated redundant SCM_IMP test.
1400 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1402 * eval.c (scm_m_body, scm_macroexp, unmemocopy, scm_eval_args,
1403 scm_deval_args): Eliminated redundant SCM_IMP tests.
1405 * hashtab.c (scm_ihashx, scm_sloppy_assx, scm_delx_x), weaks.c
1406 (scm_make_weak_key_hash_table, scm_make_weak_value_hash_table,
1407 scm_make_doubly_weak_hash_table): Fixed critical sections.
1408 Thanks to Keisuke Nishida.
1410 2000-05-05 Dirk Herrmann <D.Herrmann@tu-bs.de>
1412 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest):
1413 Fixed some goto-related initialization bugs (introduced by me).
1415 2000-05-04 Dirk Herrmann <D.Herrmann@tu-bs.de>
1417 * numbers.h (SCM_INUM0): Uses SCM_MAKINUM instead of SCM_PACK.
1419 * dynl.c (dynl_obj, DYNL_OBJ, get_dynl_obj): Removed.
1421 (DYNL_FILENAME, DYNL_HANDLE): Use SCM_CELL... macros instead of
1424 (SET_DYNL_HANDLE): Added.
1426 (scm_dynamic_object_p): Simplified.
1428 (scm_dynamic_unlink, scm_dynamic_func): Changed comment. Deliver
1429 better error message when accessing unlinked dynamic objects.
1430 Eliminated call to get_dynl_obj.
1432 2000-05-03 Marius Vollmer <mvo@zagadka.ping.de>
1434 * scmsigs.c (orig_handlers) [!HAVE_SIGACTION]: Fix declaration to
1435 be an array of function pointers instead of being a pointer to an
1436 array returning function. Thanks to Kalle Olavi Niemitalo!
1438 2000-05-03 Dirk Herrmann <D.Herrmann@tu-bs.de>
1440 * numbers.c (scm_divbigbig, scm_divbigint), numbers.h
1441 (scm_divbigbig, scm_divbigint): Don't return zero any more to
1442 indicate that a division has a remainder, return SCM_UNDEFINED
1443 instead. It is improbable that anyone actually used these
1444 functions outside of numbers.c. For this reason and due to the
1445 change in behaviour the functions are static now. Thus, if
1446 surprisingly there are users of these functions they will at least
1449 * numbers.c: Removed #ifdef SCM_BIGDIG #endif in those functions,
1450 that already have a clean dispatch order. Note: SCM_BIGDIG is
1453 * numbers.c (scm_inexact_p): Simplified.
1455 * numbers.c (scm_num_eq_p, scm_less_p, scm_max, scm_min,
1456 scm_product, scm_num2dbl, scm_angle): Reordered dispatch
1457 sequence, thereby fixing some comparisons of SCM values with
1460 * numbers.c (scm_divide): Division by zero of inums leads to an
1461 error now. (Formerly, an infinite number was returned.)
1463 Respect the fact, that scm_divbigbig does now return SCM_UNDEFINED
1464 if a division has a remainder.
1466 2000-05-02 Gary Houston <ghouston@arglist.com>
1468 * Makefile.am (INCLUDES): add ${INCLTDL} (thanks to Tim Mooney).
1470 2000-05-02 Dirk Herrmann <D.Herrmann@tu-bs.de>
1472 * numbers.c (scm_logtest, scm_division): Reordered dispatch
1473 sequence, thereby fixing some comparisons of SCM values with
1476 * numbers.h (scm_makdbl): Mark as deprecated at the point of
1479 * eval.c (SCM_CEVAL, SCM_APPLY), gh_data.c (gh_double2scm,
1480 gh_doubles2scm), numbers.c (scm_istr2flo, scm_max, scm_min,

1486 scm_random_uniform, scm_random_normal_vector_x, scm_random_exp),
1487 struct.c (scm_struct_ref), unif.c (scm_array_to_list): Replace
1488 call to scm_makdbl with a call to scm_make_real or
1489 scm_make_complex, depending on whether the imaginary part is known
1492 2000-05-01 Gary Houston <ghouston@arglist.com>
1494 * scmsigs.c: fix the definition of orig_handlers for the case
1495 that HAVE_SIGACTION is not defined (thanks to
1496 Kalle Olavi Niemitalo).
1498 * Makefile.am: remove include_HEADERS (was libguile.h)
1499 libguile.h: moved to top level directory.
1501 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1503 * numbers.c (SCM_SWAP): Moved to the top of the file to allow for
1506 * numbers.c (scm_modulo, scm_gcd, scm_lcm, scm_logand, scm_logior,
1507 scm_logxor): Reordered dispatch sequence, thereby fixing some
1508 comparisons of SCM values with integer constants.
1510 * number.c (scm_logtest): Removed some redundant SCM_{N}?IMP
1513 2000-04-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
1515 * numbers.c (scm_quotient, scm_remainder): Removed code that was
1516 conditionally compiled based on BADIVSGNS. BADIVSGNS does not
1517 occur anywhere else throughout guile.
1519 * numbers.c (scm_quotient): Fixed parameter number in error
1522 * numbers.c (scm_remainder): Reordered dispatch sequence.
1524 2000-04-25 Gary Houston <ghouston@arglist.com>
1526 * posix.c (scm_execlp): docstring fix (thanks to Martin
1529 2000-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>

1532 (suggested by Jost Boekemeier).
1534 2000-04-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
1536 * pairs.c (cxrs, scm_init_pairs): Simplify initialization of
1539 * procs.c (scm_init_iprocs), procs.h (scm_subr, scm_iproc,
1540 scm_dsubr, scm_init_iprocs): Removed.
1542 * procs.h (SCM_SUBRF, SCM_DSUBRF): Access the cell words
1543 directly instead of casting a cell to a C struct.
1545 2000-04-22 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
1547 Better modularization of GC extensions through new C level GC
1550 * weaks.c (scm_weaks_prehistory): New function: Add

1559 * guardians.h (scm_guardian_gc_init, scm_guardian_zombify): Are
1562 * guardians.c (scm_guardian_gc_init): Turned into a hook function
1563 and added to scm_before_mark_c_hook.
1564 (scm_guardian_zombify): Turned into a hook function and added to
1565 scm_before_sweep_c_hook.
1567 * async.c (scm_sys_gc_async_thunk): Run after-gc-hook.
1568 Added #include "libguile/gc.h".
1570 * gc.h: Added #include "libguile/hooks.h".
1572 * gc.c: Removed #include "libguile/guardians.h".
1573 (scm_before_gc_c_hook, scm_before_mark_c_hook,
1574 scm_before_sweep_c_hook, scm_after_sweep_c_hook,
1575 scm_after_gc_c_hook): New C level hooks.

1605 the root build directory.
1607 * numbers.c (scm_odd_p, scm_even_p): Use SCM_WRONG_TYPE_ARG
1608 instead of SCM_ASSERT (0, ...). (Some compilers will complain

1631 functions respectively signal wrong type arguments. Hopefully
1632 this will allow for easier separation when goops is integrated.

1636 * gc.c (which_seg): Use SCM2PTR to convert a non immediate SCM

1921 * async.h: kill the scm_async_t struct. having a heap cell
1922 pretending to be a C struct is not helthy, and is not needed here

1993 separate loop after processing all the currently known live
1994 guardians, so as to not introduce order dependencies (thanks to
1995 Gary Houston). note that the order problems are still there if
1996 some guardians are themselves zombies, but that's a sick case that
1997 I'm not going to worry about.
1998 also, make another outer loop to process zombified
1999 guardians (which are uncovered while marking zombies).

2079 SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): Don't initialize globals
2080 and static variables at their point of declaration, but rather in
2083 * tags.h (SCM_PACK): Automatically cast to scm_bits_t.
2085 2000-04-02 Gary Houston <ghouston@arglist.com>
2087 * guardians.c (TCONC_IN, scm_make_guardian): set the CDR of the
2088 empty tconc pair to SCM_EOL instead of SCM_BOOL_F, avoiding the
2089 use of an improper list (which breaks g_print. g_print isn't
2091 guardians.c: Added more comments and modified the make-guardian
2092 docstring. Reordered a few procedures.
2094 2000-04-01 Dirk Herrmann <D.Herrmann@tu-bs.de>
2096 * eval.c (scm_lookupcar1, scm_lookupcar, scm_m_case, scm_m_cond,
2097 scm_m_lambda, iqq, scm_m_define, scm_m_expand_body, unmemocopy,
2098 SCM_CEVAL), procs.h (SCM_TOP_LEVEL): Don't use C operators to
2101 (scm_makprom): Smob data is of type scm_bits_t.
2103 2000-03-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
2105 * backtrace.c (display_error_body), debug.c (scm_procedure_source,
2106 scm_reverse_lookup), dynl.c (scm_dynamic_link): Don't use C
2107 operators to compare SCM values.

2110 SCM_SET_DEBUGOBJ_FRAME): Update SCM_{SET_}?DEBUGOBJ_FRAME to
2111 access raw cell data with SCM_{SET_}?CELL_WORD_1.
2113 * debug.c (scm_make_debugobj): Don't use SCM_SETCAR to set types.
2115 * debug.c (scm_make_memoized), dynl.c (scm_dynamic_link): Smob
2116 data is of type scm_bits_t.
2118 2000-03-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
2120 * gdbint.c (gdb_maybe_valid_type_p), guardians.c (TCONC_EMPTYP,
2121 scm_guardian_zombify): Use SCM_EQ_P to compare SCM values.
2123 * guardians.c (GUARDIAN): Use SCM_CELL_WORD_1 for raw data.
2125 2000-03-31 Dirk Herrmann <D.Herrmann@tu-bs.de>
2127 * ports.h (scm_port): Change type of stream member to scm_bits_t.
2129 * gdbint.c (unmark_port, remark_port), ports.c (scm_markstream),
2130 strports.c (st_resize_port, scm_mkstrport), vports (sf_flush,
2131 sf_write, sf_fill_input, sf_close, scm_make_soft_port): Since
2132 streams are now of type scm_bits_t, SCM streams have to be
2135 * ports.h (SCM_SETPTAB_ENTRY, SCM_SETSTREAM): Cast input to
2138 2000-03-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2140 * coop-defs.h (struct coop_t): Added `sto'-field again because of
2141 binary compatibility---let's remove it next time we alter some
2144 * coop.c (coop_quitting_p, coop_cond_create, coop_mutex_create,
2145 coop_mother, coop_child): New variables.
2146 (mother): New function.
2147 (coop_create): New thread spawning mechanism which uses a "mother
2148 thread". The "dummy" pthreads aren't healthy enough to give birth
2149 to new threads since Linux threads thinks they are asleep.
2151 * coop-defs.h (struct coop_t): Removed dummy_mutex.
2153 * coop-defs.h, coop-threads.c (struct coop_t): Eliminate
2154 `sto'-field when GUILE_PTHREAD_COMPAT is enabled.
2156 2000-03-30 Dirk Herrmann <D.Herrmann@tu-bs.de>
2158 * arbiters.c (scm_make_arbiter), async.c (scm_async), dynwind.c
2159 (scm_internal_dynamic_wind): Smob data is always of type
2162 * arbiters.c (SCM_ARB_LOCKED, SCM_LOCK_ARB, SCM_UNLOCK_ARB):
2163 Access the locking information in cell entry 0 with
2164 SCM_{SET_}?CELL_WORD_0 instead of SCM_*CAR.
2166 * async.c (scm_run_asyncs): Use SCM_NULLP to test for the empty
2169 * dynwind.c (scm_dowinds): Use SCM_EQ_P to compare SCM values.
2171 * ports.h (SCM_PTAB_ENTRY, SCM_SETPTAB_ENTRY): Access the ptab
2172 entry data using SCM_{SET_}?CELL_WORD_1 instead of SCM_{SET}?CDR.
2174 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2176 * alist.c (scm_sloppy_assq, scm_assq), eq.c (scm_eq_p, scm_eqv_p,
2177 scm_equal_p), list.c (scm_ilength, scm_last_pair, scm_reverse,
2178 scm_sloppy_memq, scm_delq_x, scm_delq1_x), tags.h (SCM_UNBNDP):
2179 Don't use C operators == and != to compare SCM values, use
2182 * boolean.c (scm_boolean_p): Use SCM_BOOLP to determine whether a
2183 SCM value is equal to #t or #f.
2185 * eq.c (scm_eqv_p, scm_equal_p): Don't use SCM_CAR to access the
2186 cell type entry of non immediate objects of unknown type. Use
2187 SCM_CELL_TYPE instead.
2189 * gh_data.c (gh_scm2bool, gh_module_lookup), list.c
2190 (scm_sloppy_memv, scm_sloppy_member, scm_delv_x, scm_delete_x,
2191 scm_delv1_x, scm_delete1_x), scmsigs.c (scm_sigaction): Use
2192 SCM_FALSEP and SCM_TRUE_P to compare SCM values against #f and
2195 * list.c (scm_listify): Use SCM_UNBNDP to test for an unbound
2198 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2200 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread,
2201 scm_make_mutex, scm_make_condition_variable): Cast data to
2202 scm_bits_t in SCM_SET_CELL_WORD and SCM_NEWSMOB macros.
2204 * coop.c (coop_create): Set `specific' field, not `data' to NULL.
2206 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2208 * smob.h (SCM_NEWSMOB, SCM_NEWSMOB2, SCM_NEWSMOB3, SCM_SMOB_DATA,
2209 SCM_SET_SMOB_DATA, SCM_TC2SMOBNUM, SCM_SMOBNUM): To access smob
2210 data, use SCM_{SET_}?CELL_TYPE or SCM_{SET_}?WORD_[1-3].
2212 Note that this implies that smob data has always to be passed as
2213 values of type scm_bits_t.
2215 2000-03-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2217 * threads.c (scm_init_threads): Pass 0 size to scm_make_smob_type
2218 for scm_tc16_thread. As the current COOP threads are written, GC
2219 is not supposed to manage storage for threads.
2221 * error.c (scm_error): Don't try to throw an error if
2222 scm_gc_heap_lock is true.
2224 * coop.c (coop_finish): New function. Called at exit.
2225 (coop_aborthelp): Free thread structures when threads die.
2226 Finished LinuxThreads compatibility support => COOP threads now
2227 mesh with LinuxThreads.
2229 * coop-threads.c (scm_call_with_new_thread, scm_spawn_thread):
2230 Changed SETCDR --> SET_CELL_WORD_1.
2232 * coop-threads.c (scheme_launch_thread): Set word 1 of handle to 0
2235 2000-03-29 Dirk Herrmann <D.Herrmann@tu-bs.de>
2237 * boolean.h (SCM_TRUE_P): New macro.
2239 * boolean.h (SCM_FALSEP, SCM_NFALSEP, SCM_BOOLP), pairs.h
2240 (SCM_NULLP, SCM_NNULLP): Use SCM_EQ_P to compare SCM values.
2242 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2244 * continuations.h (SCM_CONTREGS, SCM_SET_CONTREGS): New macros to
2245 access continuation data.
2247 (SCM_SETJMPBUF): Deprecated. Use SCM_SET_CONTREGS instead.
2249 (SCM_JMPBUF, SCM_DYNENV, SCM_THROW_VALUE, SCM_BASE, SCM_SEQ,
2250 SCM_DFRAME): Use SCM_CONTREGS instead of SCM_CHARS to access
2253 * continuations.c (scm_make_cont), init.c (start_stack),
2254 root.c (scm_internal_cwdr): Use SCM_SET_CONTREGS instead of
2257 2000-03-28 Dirk Herrmann <D.Herrmann@tu-bs.de>
2259 * symbols.h (SCM_LENGTH, SCM_SETLENGTH): Access the length field
2260 of strings and symbols by using SCM_{SET_}?CELL_WORD_0.
2262 (SCM_CHARS, SCM_UCHARS, SCM_SETCHARS): Use SCM_{SET_}?CELL_WORD_1
2263 to access the char * field of strings and symbols.
2265 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2267 * gc.h (SCM_NEWCELL, SCM_NEWCELL2): Use SCM_SET_CELL_TYPE to set
2268 the type entry of a new cell. Added a comment about things to
2269 remember when updating the list of free cells.
2271 (SCM_FREEP, SCM_MARKEDP): Use SCM_CELL_TYPE to access the type
2274 2000-03-27 Dirk Herrmann <D.Herrmann@tu-bs.de>
2276 * pairs.h (SCM_CAR, SCM_CDR, SCM_SETCAR, SCM_SETCDR): Use
2277 SCM_CELL_OBJECT and SCM_SET_CELL_OBJECT. This change implies that
2278 with strict type checking enabled these macros will only work if
2279 given valid SCM parameters.
2281 (SCM_GCCDR): Moved to tags.h.
2283 * tags.h (SCM_GCCDR): Moved here from pairs.h.
2285 2000-03-26 Dirk Herrmann <D.Herrmann@tu-bs.de>
2287 * tags.h (SCM2PTR, PTR2SCM): Moved to gc.h.
2289 * pairs.h (scm_cell, SCM_CELLPTR, SCM_CELL_WORD*, SCM_CELL_OBJECT*,
2290 SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*, SCM_CELL_TYPE,
2291 SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK, SCM_PTR_GT,
2292 SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC, SCM_NEWCELL,
2293 SCM_NEWCELL2): Moved to gc.h.
2295 (SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR, SCM_SETAND_CDR,
2296 SCM_SETOR_CAR, SCM_SETOR_CDR): Moved to gc.h. These names should
2297 be changed, though, since the macros are not only pair related.
2301 * gc.h (SCM2PTR, PTR2SCM, scm_cell, SCM_CELLPTR, SCM_CELL_WORD*,
2302 SCM_CELL_OBJECT*, SCM_SET_CELL_WORD*, SCM_SET_CELL_OBJECT*,
2303 SCM_CELL_TYPE, SCM_SET_CELL_TYPE, SCM_PTR_LT, SCM_PTR_MASK,
2304 SCM_PTR_GT, SCM_PTR_LE, SCM_PTR_GE, SCM_CELL_WORD_LOC,
2305 SCM_NEWCELL, SCM_NEWCELL2, SCM_CARLOC, SCM_CDRLOC, SCM_SETAND_CAR,
2306 SCM_SETAND_CDR, SCM_SETOR_CAR, SCM_SETOR_CDR): Moved here from
2309 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2311 * tags.h (SCM_STRICT_TYPING): New macro that, if defined,
2312 activates strict compile time type checking for variables of
2314 (SCM, SCM_PACK, SCM_UNPACK): Define according to whether
2315 SCM_STRICT_TYPING or SCM_VOIDP_TEST are defined.
2316 (SCM_EQ_P): Defined as a macro equivalent for eq?.
2318 2000-03-25 Dirk Herrmann <D.Herrmann@tu-bs.de>
2320 * tags.h (SCM_POINTERS_MUNGED): Removed.
2322 * gc.c (scm_gc_sweep, init_heap_seg): Removed use of
2323 SCM_POINTERS_MUNGED, thus fixing some illegal casts to SCM.
2325 2000-03-24 Dirk Herrmann <D.Herrmann@tu-bs.de>
2327 * pairs.h (SCM_CELL_OBJECT, SCM_CELL_OBJECT_[0-3],
2328 SCM_SET_CELL_OBJECT, SCM_SET_CELL_OBJECT_[0-3], SCM_CELL_TYPE,
2329 SCM_SET_CELL_TYPE): Added a set of low level macros for accessing
2331 (SCM_CELL_WORD_[0-3]): Renamed from the SCM_CELL_WORD[0-3].
2333 * procs.h, procs.c: Instead of SCM_{SET_}?CELL_WORD[12], use the
2334 newly introduced SCM_{SET_}?CELL_OBJECT_[12] macros.
2336 2000-03-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2338 * tags.h: Disabled definition of SCM_VOIDP_TEST.
2340 Defining SCM as void * introduces problems which haven't been
2341 handled yet. Developers who work with these issues can enable it
2342 in their working copies.
2344 Disabling this definition exposes a set of newly introduced and
2345 older misuses of types which causes warning messages during
2346 compilation. We'll fix this successively.
2348 * gc.c (scm_mark_locations): Changed * (SCM **) X --> * (SCM *) X
2349 in order to obtain a value of type SCM.
2350 (scm_cellp): Updated with new changes to scm_mark_locations.
2352 * continuations.h (SCM_SETJMPBUF): Cast second arg into SCM.
2354 * continuations.c (scm_make_cont): Removed cast of size_t into
2357 * symbols.h (SCM_SETCHARS): Cast second arg into SCM.
2359 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2361 * numbers.h (SCM_SETNUMDIGS): Use SCM_BIGSIZEFIELD macro for
2362 shifting, not constant. Thanks to Dale P. Smith.
2364 * numbers.c (scm_sum, scm_difference): Don't test a SCM value
2365 for being less than zero. Decode it to a C value first. Again,
2368 2000-03-22 Dirk Herrmann <D.Herrmann@tu-bs.de>
2370 * numbers.h, ramap.c, struct.h, vectors.h: Don't use SCM2PTR for
2371 non scheme values. If raw data is stored in SCM variables, it has
2372 to be accessed using SCM_UNPACK until a better solution is found.
2374 2000-03-22 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2376 * tags.h (SCM_ECONSP, SCM_NECONSP): More corrections of
2377 pointer-arithmetic induced by the SCM_PACK/UNPACK change.
2379 * print.c (scm_iprin1): SCM_PACK/UNPACK corrections.
2381 * gc.c (scm_gc_sweep): SCM_PACK/UNPACK corrections.
2383 * eval.c (SCM_CEVAL, scm_unmemocar): SCM_PACK/UNPACK corrections.
2385 * dynwind.c (scm_swap_bindings): SCM_PACK/UNPACK corrections.
2387 * async.c, __scm.h: Removed lots of the old async click logic. It
2388 is possible to reinsert it by defining GUILE_OLD_ASYNC_CLICK in
2389 __scm.h. Let's try this out and dump the old code after the
2390 threads reorganization.
2391 (set-tick-rate, set-switch-rate): Conditionally removed.
2393 2000-03-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2395 * gc.c (scm_gc_mark): Bugfix 1: The recent SCM_PACK/UNPACK change
2396 made SCM values into pointers. This turned an arithmetic
2397 computation of the address of the vcell into a pointer-arithmetic
2398 one, thereby screwing up marking of structs.
2399 Bugfix 2: Removed incompletely introduced loop variable `j' used
2400 when protecting the tail array of a struct.
2402 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2404 * struct.h (SCM_STRUCT_DATA): Don't cast SCM values to pointers.
2406 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2408 * symbols.h, symbols.c (scm_strhash): Declare the string
2409 parameter as constant, since it is not modified.
2411 * symbols.c (scm_intern_obarray_soft,
2412 scm_sysintern0_no_module_lookup): Can now pass constant strings
2413 to scm_strhash without need for casting.
2415 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2417 * vectors.h (SCM_VELTS, SCM_VELTS_AS_STACKITEMS): Don't cast SCM
2418 values to pointers. Use SCM2PTR instead.
2420 2000-03-21 Dirk Herrmann <D.Herrmann@tu-bs.de>
2422 * async.c (scm_set_tick_rate, scm_set_switch_rate): Don't unpack
2423 results of SCM_INUM.
2425 2000-03-21 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2427 * init.c (scm_boot_guile_1): Renamed GUILE_GC_TRIGGER_1 -->
2428 GUILE_MIN_YIELD_1, GUILE_GC_TRIGGER_2 --> GUILE_MIN_YIELD_2.
2429 GUILE_MIN_YIELD_X now take *positive* fractions of heap size.
2431 * gc.c, gc.h (SCM_MIN_YIELD_1, SCM_MIN_YIELD_2,
2432 min_yield_fraction, min_yield, adjust_min_yield): Renamed from
2433 SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2, gc_trigger_fraction,
2434 gc_trigger, adjust_gc_trigger.
2436 * gc.c (alloc_some_heap): Further improvement of minimal heap size
2438 (SCM_MAX): New macro.
2439 (scm_freelist_t): New field: collected_1. Previous amount of
2441 (gc_sweep_freelist_finish): Trigger based on two last values of
2442 freelist->collected to avoid unnecessary allocation due to
2444 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2):
2445 Adjusted to 45000 cells, 40% and 40%. Gives quick startup
2446 without extra heap allocation.
2448 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2450 * numbers.h (SCM_MAKINUM): The parameter to SCM_MAKINUM should
2451 already be a C value. No need to unpack it.
2453 * numbers.c (scm_long_long2num): Cast the parameter to scm_bits_t
2454 if we know it fits into an inum.
2456 * ramap.c (ramap_rp): An scm_tc7_[ui]vect object does point to a
2457 field of long values. In contrast, SCM_VELTS accesses a field of
2460 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2462 * gc.c (scm_gc_stats): Inserted explanation of local_scm_mtrigger
2464 (scm_gc_yield_1): New variable: Holds previous yield. Used to
2465 make better judgements.
2466 (gc_sweep_freelist_finish): Inserted explanation of use of
2469 * print.h, stacks.h, options.c, options.h: Changed C++
2472 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2474 * tags.h (SCM2PTR, PTR2SCM): Use SCM_PACK / SCM_UNPACK correctly.
2476 * numbers.h (SCM_INUMP, SCM_MAKINUM, SCM_INUM0, SCM_COMPLEX_REAL,
2477 SCM_COMPLEX_IMAG, SCM_NUMP, SCM_BDIGITS): Use SCM_PACK /
2478 SCM_UNPACK / SCM2PTR correctly.
2480 2000-03-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2482 * gc.c (adjust_gc_trigger): Improved documentation.
2483 (alloc_some_heap): Since gc_trigger is used against
2484 freelist->collected, this is the value which should be used to
2485 predict minimum growth.
2487 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2489 * eval.h: Fix mixup of packed/unpacked SCM values. (Thanks
2490 Thien-Thi Nguyen for the patch.)
2492 2000-03-20 Dirk Herrmann <D.Herrmann@tu-bs.de>
2494 * numbers.c (scm_ash): Fixed typing problems with the second
2495 parameter and added some documentation. (Thanks Thien-Thi Nguyen
2496 for indicating the problem.)
2498 2000-03-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2500 * gc.c, gc.h (scm_gc_yield): New variable.
2501 (adjust_gc_trigger): Use scm_gc_yield.
2502 (alloc_some_heap): Use scm_gc_yield instead of
2503 scm_gc_cells_collected.
2505 * coop-threads.c: Addd #include "root.h", #include "strings.h".
2507 * debug.c: Added #include "root.h". (Thanks to Thien-Thi Nguyen.)
2509 * gc.c (scm_gc_for_newcell, adjust_gc_trigger): Improved GC
2510 trigger adjustmeant: Take yield (freed cells) for all freelists
2512 (SCM_INIT_HEAP_SIZE_1, SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Tuned
2513 to 50000 cell heap with 45% trigger.
2514 (scm_gc_cells_collected): Reintroduced.
2515 (SCM_HEAP_SIZE): New macro.
2516 (scm_gc_sweep): Reintroduced correct computation of
2517 scm_cells_allocated.
2518 (scm_freelist_t): Corrected commentary for field `cluster_size':
2519 Clustersize counts objects, not cells; New member
2520 `clusters_allocated'.
2522 2000-03-19 Michael Livshin <mlivshin@bigfoot.com>
2524 * *.[hc]: add Emacs magic at the end of file, to ensure GNU
2527 2000-03-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2529 * threads.h: Added #include "libguile/throw.h". (Thanks to
2532 2000-03-18 Michael Livshin <mlivshin@bigfoot.com>
2534 * tags.h: (SCM_DOUBLE_CELLP, SCM_NDOUBLE_CELLP): new macros (bad
2535 names, anyone got any better ones?)
2537 * gc.h: (typedef struct scm_freelist_t) remove from here.
2539 * gc.c: (CELL_UP, CELL_DN) made these macros take additional
2540 parameter (the span).
2541 (CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK) new macros.
2542 (typedef struct scm_freelist_t) moved here from gc.h, it had no
2543 business being externally visible.
2544 (typedef struct scm_heap_seg_data_t) renamed from
2545 scm_heap_seg_data, to be style-compliant.
2546 (scm_mark_locations) if the possible pointer points to a
2547 double-cell, check that it's properly aligned.
2548 (init_heap_seg) align double-cells properly, work with the
2549 assumption that the segment size divides cleanly by cluster size.
2550 (round_to_cluster_size) new function.
2551 (alloc_some_heap, make_initial_segment) use round_to_cluster_size
2552 to satisfy the new init_heap_seg invariant.
2554 2000-03-18 Dirk Herrmann <D.Herrmann@tu-bs.de>
2556 * _scm.h: Don't include async.h everywhere...

2611 2000-03-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2613 * gc.c, gc.h: Cleanup of the change of 2000-03-15.
2614 Cluster sizes are now independent of GC trigger values.
2615 GUILE_GC_TRIGGER_n can now specify a relative trigger value:
2616 A negative integer gives fraction of total heap size in percent.
2617 (SCM_GC_TRIGGER_1, SCM_GC_TRIGGER_2): Default values set to -40.
2619 * init.c (scm_boot_guile_1): Introduced new variable
2620 GUILE_MAX_SEGMENT_SIZE; New environment variable names:
2621 GUILE_INIT_SEGMENT_SIZE_1, GUILE_GC_TRIGGER_1,
2622 GUILE_INIT_SEGMENT_SIZE_2, GUILE_GC_TRIGGER_2
2624 2000-03-16 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2626 * __scm.h (GC_FREE_SEGMENTS): Disable this until we have made
2627 freeing of segment work with the new GC scheme. (Thanks to
2628 Michael Livshin.) Oops, also happened to make GUILE_NEW_GC_SCHEME
2629 the default, but I'll let this change stay in CVS Guile since this
2630 code is not expected to contain serious bugs.
2632 2000-03-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2634 * gc.c, gc.h (scm_map_free_list): Define also if GUILE_DEBUG is
2636 (scm_free_list_length): New procedure (GUILE_DEBUG).
2637 Fixed a small but serious bug introduced by the previous change.
2639 * gc.c (scm_gc_sweep): Moved variable n_objects to inner sweep
2640 loop and declare as register.
2642 * gc.c (scm_gc_sweep): Sigh... forgot to clear private freelists
2645 Wed Mar 15 08:27:04 2000 Greg J. Badros <gjb@cs.washington.edu>
2647 * fluids.c: Docstring patch from Keisuke Nishida. Some
2648 reindentation, too, and a couple formals renamed. Should
2649 fluid-set! return UNSPECIFIED instead of a value?
2651 Wed Mar 15 08:24:58 2000 Greg J. Badros <gjb@cs.washington.edu>
2653 * Makefile.am: Separate out DOT_X_FILES and DOT_DOC_FILES, and
2654 generate the latter from the concrete listing of the former. Then
2655 make guile-procedures.txt depend on DOT_DOC_FILES instead of
2656 *.doc, so that rebuilding it works.
2658 Wed Mar 15 08:12:14 2000 Greg J. Badros <gjb@cs.washington.edu>
2660 * libguile.h: Include libguile/validate.h. Thanks Keisuke Nishida!
2662 * guile-snarf.awk.in: Replace docstring line-ending \n" and \n\n"
2663 with nothing and \n, respectively. Thanks Keisuke Nishida for
2664 noticing this problem.
2666 2000-03-15 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2668 * __scm.h (GUILE_NEW_GC_SCHEME): Define this if you want to test a
2669 new way of allocating heap. It makes Guile fast, but still
2672 * gc.c, gc.h, pairs.h, init.c: Implementation of a new way of
2673 allocating heap. The basic idea is to trigger GC every Nth
2674 allocated cell and grow heap when free list runs out. The scheme
2675 has been extended so that GC isn't triggered until all remaining
2676 cells are used. The implementation is also prepared for
2677 development in the direction of POSIX threads.
2679 * gc.c (SCM_EXPHEAP): In order to grow by a factor of 1.5,
2680 SCM_EXPHEAP should return half of the heap size.
2682 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2684 The following change to init.c is only enabled if Guile was
2685 configured with --enable-guile-debug.
2687 * init.c (scm_i_getenv_int): New function.
2688 (scm_boot_guile_1): Use the environment variables
2689 GUILE_INIT_HEAP_SIZE, GUILE_INIT_HEAP_SIZE2 to select heap size if
2690 they exist. (This may be replaced by a Scheme level mechanism in
2693 * objprop.c (s_scm_set_object_property_x): Use scm_assq instead of
2694 scm_assoc. (Thanks to Keisuke Nishida.)
2696 2000-03-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2698 * eval.c, lang.c, lang.h (scm_lisp_nil, scm_lisp_t): Renamed from
2699 scm_nil, scm_t. (Thanks to Keisuke Nishida.)
2701 2000-03-14 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2703 * init.c (scm_boot_guile_1): Use same initial segment size for
2704 1-word and 2-word segments. Having the smaller size causes Guile
2705 to GC too often. Obviously something needs to be done to allow
2706 for a smaller 2-word segment without this to happen. (The amount
2707 of heap for each type should be automatically adapted to the
2708 application somehow.)
2710 [Almost all of these changes should be documented in the NEWS
2713 * gc.h (scm_freelist_t): New type.
2715 * pairs.h (SCM_NEWCELL, SCM_NEWCELL2): Use new style freelists.
2717 * gc.c (SCM_INIT_HEAP_SIZE): Changed from 32768 --> 40000 so that
2718 all of Guile basics fits into one segment and there suitable room
2720 (SCM_EXPHEAP): Now takes an argument. Grow by a factor of 1.5
2722 (scm_freelist, scm_freelist2): Now of type scm_freelist_t.
2723 Freelists now contains information about object span, cells
2724 collected and amount of cells in heap segments belonging to the
2726 (scm_heap_size, scm_gc_cells_collected): Removed.
2728 * init.c (scm_boot_guile_1): Make 2-word segment 8K (512 cells).
2730 * Makefile.am (libguile_la_LDFLAGS): Bumped library version
2733 * __scm.h eq.c, eval.c, gc.c, gc.h, gh_data, hash.c, numbers.c,
2734 numbers.h, objects.c, ramap.c, random.c, unif.c, unif.h: Extensive
2735 rewrite of handling of real and complex numbers.
2736 (SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
2737 removed along with the support for floats. (Float vectors are
2740 * tags.h (scm_tcs_bignums): Removed.
2741 (scm_tc16_bigpos, scm_tc16_bigneg): Replaced by scm_tc16_big.
2742 Use SCM_BIGSIGN(x) to test for sign!
2743 (scm_tc16_big): The new bignum type.
2744 (SCM_REAL_PART, SCM_IMAG_PART): Removed.
2746 * numbers.h (SCM_BIGSIGN): Sign moved to bit 16.
2747 (scm_makdbl): Deprecated.
2748 (SCM_NEWREAL, SCM_NEWCOMPLEX): New macros.
2749 (SCM_SINGP): Deprecated.
2751 (SCM_INEXP, SCM_CPLXP): Deprecated.
2752 (SCM_INEXACTP, SCM_COMPLEXP): New macros.
2753 (SCM_COMPLEX_REAL, SCM_COMPLEX_IMAG): Renamed from
2754 SCM_REAL, SCM_IMAG (and now only valid for complex numbers).
2755 (SCM_REAL, SCM_IMAG): New, *deprecated*, selectors which work both
2756 for doubles and complex numbers.
2757 (SCM_REAL_VALUE): New selector for doubles.
2758 (scm_double_t, scm_complex_t): New types.
2761 * numbers.c (scm_floprint, scm_floequal): Removed.
2762 (scm_print_real, scm_print_complex, scm_real_equalp,
2763 scm_complex_equalp): New functions.
2765 * unif.c (scm_makflo): Removed.
2767 * smob.h (SCM_SMOB_PREDICATE): New macro.
2768 (SCM_NEWSMOB2, SCM_RETURN_NEWSMOB2, SCM_NEWSMOB3,
2769 SCM_RETURN_NEWSMOB3): New macros.
2771 1999-11-21 Michael Livshin <mlivshin@bigfoot.com>
2773 The following changes implement primitive support for double cells
2774 (i.e. four-word cells) and change the representation of some
2775 things to multi-cells instead of cons+malloc. (Applied and
2778 * pairs.h (SCM_NEWCELL2): double-cell variants of SCM_NEWCELL.
2779 (SCM_CELL_WORD, SCM_CELL_WORDLOC, SCM_SET_CELL_WORD): primitive
2780 multi-cell access macros (used by the ones below).
2781 (SCM_CELL_WORD[0-3], SCM_SET_CELL_WORD[0-3]): multi-cell access
2784 * gc.c (scm_freelist2): multi-cell freelists.
2785 (inner_map_free_list): map_free_list, parameterized on ncells.
2786 "nn cells in segment mm" was misleading for ncells > 1; changed to
2787 "objects". still print cells too, though.
2788 (scm_map_free_list): rewritten using inner_map_free_list.
2789 (scm_check_freelist): get freelist as parameter, since now we have
2791 (scm_debug_newcell2): multi-cell variants of
2793 (scm_gc_for_newcell): take ncells and freelist pointer as
2795 (scm_gc_mark): add case for tc7_pws (procedures with setters are
2797 (scm_gc_sweep): don't free the float data, since it's not malloced
2799 (init_heap_seg): didn't understand what n_new_objects stood for,
2800 so changed to n_new_cells.
2801 (make_initial_segment): new function, makes an initial segment
2802 according to given ncells.
2803 (scm_init_storage): call make_initial_segment, for ncells={1,2,3}.
2805 * numbers.c (scm_makdbl): no malloc'ing needed, so the
2806 {DEFER,ALLOW}_INTS thing removed.
2808 * numbers.h (struct scm_dbl): changed to represent a double cell,
2809 with the number in the second half.
2811 * dynwind.c: changed the wind-guards representation to double
2814 * procs.c, procs.h: changed the procedure-with-setter representation
2817 * async.c, async.h: made async representation a double cell.
2819 * dynl.c: made dynamic_obj representation a double cell.
2821 2000-03-13 Gary Houston <ghouston@arglist.com>
2823 * ports.c (flush_void_port): renamed to flush_port_default.
2824 (end_input_void_port): renamed to end_input_default.
2826 * init.c (scm_standard_stream_to_port): create a void port instead
2827 of opening /dev/null if the standard file descriptors are bad.
2828 advantages: no portability problems, doesn't waste a file descriptor,
2829 simplifies the code (thanks to Marius for the idea).
2831 * vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
2833 * void ports: make reading from a void port give EOF instead of
2835 * ports.c (s_scm_sys_make_void_port): modified docstring.
2836 (fill_input_void_port): new proc.
2837 (scm_init_ports): set up fill_input_void_port.
2838 * ports.c (scm_port_non_buffer): new proc.
2839 (scm_void_port): call scm_port_non_buffer.
2841 * fports.c (scm_setvbuf): docstring: remove the fcntl documentation
2842 which was incorrectly appended.
2844 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2846 * guile-doc-snarf.in: Don't use absolute path for `sed'. (Note
2847 that we can't use autoconf for this. Autoconf itself relies on
2848 the existence of `sed' somewhere on your path.) (Thanks to Dirk
2851 2000-03-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2853 * Makefile.am (libguile_la_SOURCES): Moved iselect.c here from
2854 EXTRA_libguile_la_SOURCES.
2856 * iselect.h: Always declare scm_internal_select.
2858 * iselect.c (scm_internal_select): Added SCM_ASYNC_TICK at the
2859 end. Also let scm_internal_select be a real function also when
2862 * __scm.h (SCM_TICK): Oops! Forgot to put SCM_ASYNC_TICK here...
2864 2000-03-13 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2866 * __scm.h (SCM_ALLOW_INTS, SCM_REALLOW_INTS): Removed call to
2867 SCM_ASYNC_TICK. (This is a preparation for POSIX threads support,
2868 and kind of an experiment: Will this cause problems?)
2870 Sun Mar 12 13:26:30 2000 Greg J. Badros <gjb@cs.washington.edu>
2872 * Makefile.am: Added *.doc to DISTCLEANFILES.
2874 2000-03-12 Gary Houston <ghouston@arglist.com>
2876 * fports.c (scm_fdes_to_port): call fcntl F_GETFL to test that
2877 the fdes is valid before doing anything else. check that
2878 the file descriptor supports the modes required.
2879 (scm_fport_buffer_add): don't throw an error if fstat doesn't
2880 work: just use the default buffer size.
2882 * throw.c: change an outdated comment about scm_internal_catch
2883 BODY: it doesn't take a jumpbuf arg.
2885 * init.c (scm_standard_stream_to_port): install a handler in case
2886 scm_fdes_to_port throws an error. don't check here whether the
2887 file descriptor is valid, since scm_fdes_to_port will do that.
2888 set the revealed count depending on whether the port got the
2889 standard file descriptor.
2890 (stream_body_data): new type.
2891 (stream_body, stream_handler): new procs.
2893 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2895 * stacks.c, stacks.h, struct.c, tags.h, unif.c (scm_bits_t):
2896 Renamed from SCMWORD.
2898 * tags.h (SCM_NCELLP): Removed (SCMWORD).
2900 * arbiters.c (SCM_ARB_LOCKED): Use SCM_UNPACK_CAR.
2902 * async.c, boolean.h, debug.c, dynl.c, dynwind.c, eval.c, eval.h,
2903 feature.h, filesys.h, fluids.h, fports.c, fports.h, gc.c, gc.h,

2908 throw.c, unif.c, unif.h, variable.h, vectors.h, weaks.c,
2909 weaks.h (SCM_PACK, SCM_UNPACK, SCM_UNPACK_CAR): Renamed from
2910 SCM_ASSCM, SCM_ASWORD, SCM_CARW).
2912 * numbers.h (SCM_SRS, SCM_INUM): Corrected SCM_ASSCM/ASWORD fixes.
2914 * alist.c, eval.c, net_db.c, posix.c, print.c, snarf.h, struct.c,
2915 tags.h: Fixed copyright notices.
2917 * struct.c, coop-threads.c: SCM_ASSCM/ASWORD fixes.
2919 2000-03-12 Marius Vollmer <mvo@zagadka.ping.de>
2921 * init.c (scm_standard_stream_to_port): Check whether the file
2922 descriptor is valid and substitute "/dev/null" when not.
2924 2000-03-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2926 * coop-defs.h (struct timespec): Conditionally defined.
2928 * coop.c (coop_condition_variable_timed_wait_mutex): Use ETIMEDOUT
2931 * readline.c (match_paren): Bugfix: First arg to select is not
2932 number of descriptors but the number of the highest descriptor +
2935 This is a preliminary attempt at a cleanup of the threads support
2936 code. It moves things to better places, makes arguments more
2937 consistent with the POSIX API (which is used in GNOME's glib), and
2938 adds new functionality.
2940 * readline.c (scm_init_readline): Added new arg to scm_init_mutex.
2942 * coop-defs.h (scm_mutex_trylock): New macro: alias for
2944 (scm_cond_init): Changed definition to
2945 coop_new_condition_variable_init.
2947 * coop.c: #include <errno.h>
2948 (coop_timeout_qinsert): Moved here from iselect.c
2949 (coop_new_mutex_init, coop_new_condition_variable_init): New
2950 functions. The strange names are temporary. Use scm_mutex_init
2951 and scm_cond_init instead.
2952 (coop_mutex_trylock): New function. Uses errno.h:EBUSY. errno.h
2953 is ANSI C, but should we check for individual error codes in
2955 (coop_condition_variable_timed_wait_mutex): New function.
2956 (coop_key_create, coop_setspecific, coop_getspecific,
2957 coop_key_delete): New functions.
2959 * iselect.c (coop_timout_qinsert): Moved to coop.c
2961 2000-03-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
2963 * pairs.h (SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR,
2964 SCM_SETOR_CDR): Corrected SCM_ASSCM/WORD fixes.
2966 * tags.h (SCM_VOIDP_TEST): Renamed from VOIDP_TEST.
2969 * objects.h (SCM_CLASS_FLAGS, SCM_OBJ_CLASS_FLAGS,
2970 SCM_SET_CLASS_INSTANCE_SIZE), struct.h (SCM_STRUCT_VTABLE_DATA),
2971 proc.h (SCM_CLOSCAR): SCM_ASSCM/WORD fixes.
2973 * eval.c (scm_lookupcar1): Inserted SCM_ASWORD in expressions
2976 2000-03-11 Dale P. Smith <dpsm@en.com>, applied by Greg J. Badros, <gjb@cs.washington.edu>
2978 * numbers.c (scm_copy_big_dec, scm_copy_smaller, scm_big_ior,
2979 scm_big_xor, scm_big_and, scm_big_test): Added new lowlevel bignum
2980 logical functions from SCM.
2982 (logand, logior, logxor, logtest, logbit?): Extended scheme
2983 logical functions to use bignums from SCM.
2985 (lognot): Removed call to `SCM_VALIDATE_INUM' that prevented
2986 lognot from using bignums.
2988 Thu Mar 9 11:33:25 2000 Greg J. Badros <gjb@cs.washington.edu>
2990 * vectors.h (SCM_VELTS_AS_STACKITEMS): Added this macro to help in
2991 eliminating some warnings.
2993 * unif.c, strports.c, print.c, options.c: Fix some warnings on
2996 * gc.c, gc.h: Added scm_return_first_int(), and added comment re:
2997 what the scm_return_first* functions do.
2999 2000-03-09 Han-Wen Nienhuys <hanwen@cs.uu.nl>, applied by Greg J. Badros, <gjb@cs.washington.edu>
3001 * libguile/*.[ch]: make a distinction between SCM as a generic
3002 name for a Scheme object (now a void*), and SCM as 32 bit word for
3003 storing tags and immediates (now a long int). Introduced
3004 SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
3005 code in the process: arbiter.c (use macros), unif.c (scm_array_p),
3007 Wed Mar 8 10:15:59 2000 Greg J. Badros <gjb@cs.washington.edu>
3009 * numbers.c: Use SCM_VALIDATE_LONG_COPY, and longs, not ints, in
3010 various logXXX primitives. Thanks Eric Moore!
3012 Tue Mar 7 08:05:22 2000 Greg J. Badros <gjb@cs.washington.edu>
3014 * run-test, remaining-docs-needed: Added these scripts. The
3015 second one is only temporary until the docstring additions are
3016 complete. run-test may best live on, but is here mostly for
3017 convenience and awareness for now.
3019 * hash.c: Docs, minor cleanup patch from Dirk Herrman.
3021 Thu Mar 2 16:06:58 2000 Greg J. Badros <gjb@cs.washington.edu>
3023 * error.h, error.c: Added `scm_wrong_type_arg_msg' to support
3024 displaying the expected type. Use SCM_LISTn in a couple places
3025 instead of scm_cons-ing by hand.
3027 * __scm.h: Added SCM_ASSERT_TYPE macro.
3029 * validate.h, scm_validate.h: Added the former, as a renamed
3030 version of the latter with SCM_ASSERT_TYPE used in
3031 SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
3033 * Makefile.am: Rename scm_validate.h to validate.h.
3035 * *.c, *.h: Include validate.h, not scm_validate.h (old name's
3036 prefix was superfluous).
3038 Thu Mar 2 15:33:12 2000 Greg J. Badros <gjb@cs.washington.edu>
3040 * hashtab.c: Improved documentation for lots of functions. Added
3041 handwritten docs for `hash-fold'.
3043 Thu Mar 2 15:13:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3045 * list.c: Added hand-written docs for `del{q,v,ete}1!'.
3047 Thu Mar 2 12:38:30 2000 Greg J. Badros <gjb@cs.washington.edu>
3049 * list.c: Moved append docs to append! Thanks Dirk Hermann. Also,
3050 added append docs from R4RS.
3052 * strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
3053 Thanks Dirk Hermann!
3055 * chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
3056 deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
3058 * *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
3059 Drop use of SCM_P for function prototypes... assume an ANSI C
3060 compiler. Thanks Dirk Hermann!
3062 Sat Feb 19 12:20:12 2000 Greg J. Badros <gjb@cs.washington.edu>
3064 * ports.c: Made `set-port-column!' and `set-port-line!' each
3065 return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
3066 that caused a seg fault. Also fixed `set-port-column!'s
3067 docstring. Thanks Han-Wen Nienhuys for finding the bug!
3069 Sun Feb 13 19:11:42 2000 Greg J. Badros <gjb@cs.washington.edu>
3071 * arbiters.c, eq.c, gc.c, guardians.c, list.c, ports.c, print.c,
3072 regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
3073 strings.c, variable.c: Added lots of documentation, cleaned up
3074 some existing documentation. Occasionally changed formal params
3075 to match docs. Also folded an #ifdef into the inners of a
3076 primitive instead of having two copies of the primitive
3077 (`get-internal-real-time', from stime.c)
3079 Sun Feb 13 18:12:19 2000 Greg J. Badros <gjb@cs.washington.edu>
3081 * ports.c: Added docs for primitives missing them. Written by
3084 Sun Feb 13 09:40:36 2000 Greg J. Badros <gjb@cs.washington.edu>
3086 * guile-doc-snarf.in: Use ${AWK} -f guile-func-name-check, not
3087 just execing guile-func-name-check. Thanks Michael Livshin!
3089 Thu Feb 10 11:43:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3091 * guile-snarf.awk.in: Tweak to work with Sun/HP awk, removed some
3092 dead code. Patch from Michael Livshin.
3094 * guile-doc-snarf.in: Tweak to work with Sun/HP sh. Patch from
3097 2000-02-09 Gary Houston <ghouston@arglist.com>
3099 * init.c (scm_init_standard_ports): when stdout is a tty, make the
3100 current-output-port unbuffered by default. this is less confusing
3101 for interactive use. it was line-buffered because of a
3102 performance problem with unbuffered ports, but I think it will be
3105 2000-02-08 Gary Houston <ghouston@arglist.com>
3107 * __scm.h: don't define long_long or ulong_long if HAVE_LONG_LONGS
3110 * stime.c (scm_localtime, scm_mktime): if neither HAVE_TM_ZONE nor
3111 HAVE_TZNAME are defined, use an empty string instead of giving two
3112 spurious compile-time errors.
3114 Tue Feb 8 13:57:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3116 * ports.c: Doc patches from Richard Kim. Pasted from MIT Scheme.
3119 Mon Feb 7 09:07:31 2000 Greg J. Badros <gjb@cs.washington.edu>
3121 * macros.c: Doc patches from Richard Kim. Pasted from scm.texi.
3123 Sun Feb 6 20:26:21 2000 Greg J. Badros <gjb@cs.washington.edu>
3125 * pairs.c: Doc patches from Richard Kim. Pasted from MIT Scheme
3126 (which is GNU GPL'd).
3128 2000-01-31 Gary Houston <ghouston@arglist.com>
3130 * strings.h: don't use SCM_P. don't include <string.h>.
3131 * error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
3133 * strings.c (scm_string_ref): make the 2nd argument compulsory.
3134 previously it defaulted to zero for no good reason that I can see.
3135 use a local variable for SCM_INUM (k). replace
3136 SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
3138 (scm_makfromstr): cosmetic changes.
3140 (scm_string): Accept only chars in the list, not strings, for
3141 conformance to R5RS (particularly for list->string, which is
3142 supposed to be the inverse of string->list.) remove
3143 SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
3144 scm_makstr handles the cell allocation. when reporting wrong-type
3145 arg, don't report the position as 1.
3147 * posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
3149 2000-01-29 Gary Houston <ghouston@arglist.com>
3151 * posix.c (scm_pipe): rewrote the docstring.
3153 * filesys.c (scm_select, retrieve_select_type, get_element,
3154 fill_select_type, set_element): modified so that Scheme
3155 "select" tests port buffers for the ability to provide input
3156 or accept output. Previously only the underlying file descriptors
3157 were checked. Rewrote the docstring.
3159 Thu Jan 27 10:14:25 2000 Greg J. Badros <gjb@cs.washington.edu>
3161 * vectors.c, symbols.c, strorder.c: Documentation cut and pasted
3162 from Gregg Reynolds. Thanks Gregg!
3164 Thu Jan 27 09:59:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3166 * strop.c (scm_i_index): Obfuscated commented-out SCM_DEFINE by
3167 adding "x" prefix to the line so that guile-func-name-check
3168 doesn't complain unnecessarily.
3170 Wed Jan 26 17:33:52 2000 Greg J. Badros <gjb@cs.washington.edu>
3172 * throw.c: Factor out an #ifdef/#else/#endif choice more finely
3173 for maintainability.
3175 * strop.c: Documentation added by Gregg A. Reynolds. Pasted in
3178 Wed Jan 26 10:02:11 2000 Greg J. Badros <gjb@cs.washington.edu>
3180 * tag.c: Added doc for `tag', but mark as deprecated since Mikael
3181 suggests removing tag.c altogether (and using a new `class-of'
3184 * strings.c: Added documentation from Gregg A. Reynolds. Edited
3185 a bit by me to use FOO instead of @var{foo} and to have the
3186 summary come before preconditions on input. Also dropped trailing
3189 * gsubr.c: Do not use SCM_DEFINE for `gsubr-apply'. Register the
3190 function with scm_make_subr_opt w/ last arg of 0 so it is not
3191 visible at the Scheme level. Mikael says that this is the right
3192 thing because the first arg to the proc is the guts of a compiled
3193 closure and shouldn't be exposed to the Scheme level.
3195 Tue Jan 25 17:15:47 2000 Greg J. Badros <gjb@cs.washington.edu>
3197 * sort.c: typo in comment fixed.
3199 * keywords.c: Added documentation.
3201 * guardians.c: Added documentation (could be better).
3203 * gc.c: Added docs for gc-set-debug-check-freelist.
3205 * eq.c: Added docs for eq?, eqv? equal? abridged from R4RS.
3207 * boolean.c: Added docs for `not', `boolean?' (by hand).
3209 Tue Jan 25 13:28:56 2000 Greg J. Badros <gjb@cs.washington.edu>
3211 * random.c: Added documentation, from SLIB page:
3212 http://angela.ctrl-c.liu.se/~calle/scheme/slib_toc.html
3214 Mon Jan 24 17:50:20 2000 Greg J. Badros <gjb@cs.washington.edu>
3216 * variable.c, version.c: Added documentation, written by hand
3217 since I could not find anything already written that was
3220 2000-01-23 Gary Houston <ghouston@arglist.com>
3222 * filesys.c (scm_chown): omit port/fdes support if HAVE_FCHOWN is
3223 not defined (thanks to Richard Y. Kim).
3225 Thu Jan 20 13:00:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3227 * Makefile.in: Removed, this is auto-generated.
3229 Thu Jan 20 11:33:47 2000 Dirk Hermann <dirk@ida.ing.tu-bs.de> --applied 01/20/00 gjb
3231 * list.c: Put some variable initialization code at the point of
3232 declaration; Added a comment for list*; Formatting changes.
3234 * load.c: use SCM_NNULLP to make sure the end of a list is not
3237 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3239 * backtrace.c (scm_display_error_message): Bugfix: Don't use
3240 result of scm_list_p as C boolean.
3241 (scm_display_error_message, scm_set_print_params_x): Use new
3242 validation macros. (Thanks to Dirk Herrmann.)
3244 * net_db.c (scm_resolv_error): Cast result from hstrerror.
3246 * strports.c (st_end_input): Inserted parenthesis to get operator
3249 * list.h (scm_init_list): Removed SCM_P around prototypes.
3251 * fports.c, list.c, numbers.c, ports.c, stime.c, symbols.c,
3252 filesys.c, posix.c: Converted docstrings to ANSI C format and
3253 escaped " occurring inside string literals.
3255 Tue Jan 18 13:21:08 2000 Mikael Djurfeldt <mdj@r11n07-s.pdc.kth.se>
3257 * posix.c (scm_mknod): Escape " occuring inside docstring.
3259 2000-01-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3261 * alist.c, chars.c, debug.c, dynl.c, dynwind.c, error.c, eval.c,
3262 evalext.c, filesys.c, gc.c, hash.c, hashtab.c, ioext.c,
3263 keywords.c, list.c, load.c, macros.c, net_db.c, numbers.c,
3264 objprop.c, ports.c, posix.c, print.c, procprop.c, procs.c,
3265 ramap.c, regex-posix.c, root.c, scmsigs.c, simpos.c, socket.c,
3266 stacks.c, stime.c, strings.c, strop.c, strports.c, struct.c,
3267 symbols.c, throw.c, unif.c, vectors.c, version.c, vports.c,
3268 weaks.c: Converted docstrings to ANSI C format.
3270 * filesys.c (scm_chmod), simpos.c (scm_system), version
3271 (scm_version), vports (scm_make_soft_port): Escape " occuring
3274 Mon Jan 17 11:41:22 2000 Greg J. Badros <gjb@cs.washington.edu>
3276 * scm_validate.h: Added SCM_VALIDATE_ULONG_COPY,
3277 SCM_VALIDATE_LONG_COPY
3279 * numbers.c: Use SCM_VALIDATE_ULONG_COPY, instead of
3280 SCM_VALIDATE_INUM_COPY to let bigger numbers be used. Rename a
3281 couple of formal arguments (and fix their uses) to make arguments
3282 match the documentation.
3284 2000-01-14 <mstachow@alum.mit.edu>
3286 * Makefile.am: Augment path when running guile-doc-snarf so
3287 guile-func-name-check is found.
3289 Fri Jan 14 09:34:55 2000 Greg J. Badros <gjb@cs.washington.edu>
3291 * scm_validate.h (SCM_NUM2LONG_DEF): Fix this macro to just use
3292 def, not SCM_MAKINUM(def); thanks Janis Bzerins!
3294 Wed Jan 12 00:06:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3296 * net_db.c (s_scm_inet_makeaddr): Use SCM_NUM2ULONG since that's
3297 the way guile-1.3.4 worked, but #if 0 out the version using
3298 SCM_VALIDATE_INUM_COPY for stricter testing.
3300 Tue Jan 11 18:24:18 2000 Greg J. Badros <gjb@cs.washington.edu>
3302 * guile-doc-snarf.in: Use new $fullfilename for running
3303 guile-func-name-check, and put "$fullfilename" and "$filename" in
3304 quotes at uses to make sure re-splitting on whitespace does not
3305 occur (so filenames w/ embedded whitespace would work okay, though
3306 I sure hope we never have to deal with that! :-) ). Thanks to
3307 Mikael for pointing out the source_dir != build_dir was broken.
3309 Tue Jan 11 17:42:40 2000 Greg J. Badros <gjb@cs.washington.edu>
3311 * scm_validate.h: Added SCM_NUM2LONG_DEF macro. Make
3312 SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
3313 SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
3314 macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
3317 * ports.c (scm_port_closed_p): Validate that the arg is a PORT,
3318 then return whether it's an open port (was validating that it was
3319 an open port -- this was a bug I introduced back in December, but
3320 my careful reading of diffs caught it).
3322 * numbers.c: Recombine the two conditional-compilation paths for
3323 all the log* primitives -- they were split based on #ifndef
3324 scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
3325 some bugs and inconsistencies in the two sets of implementations.
3326 (scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
3328 * ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
3329 SCM_VALIDATE_INUM_COPY once where it should've been used.
3331 * fluids.c (scm_internal_with_fluids): Use
3332 SCM_VALIDATE_LIST_COPYLEN.
3334 * filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
3335 this is questionable as it relaxes type safety, but other changes
3336 were useful and all SCM_NUM2LONG's should probably be
3337 revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
3339 * evalext.c: line-break change on 1 line.
3341 * eval.c (nconc2last): Takes a non-empty list as its first
3342 argument, not just a list.
3344 * dynl.c: Use new SCM_COERCE_ROSTRING macro.
3346 Tue Jan 11 15:44:23 2000 Greg J. Badros <gjb@cs.washington.edu>
3348 * dynl.c, feature.c, filesys.c, fports.c, list.c, load.c,
3349 net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
3352 * symbols.c (scm_sysintern0): Fixed the function name in a
3353 scm_misc_error invocation.
3355 * print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
3356 use scm_return_first to ward off latent GC bug that Mikael caught.
3358 * async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
3359 used before but should've been.
3361 2000-01-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3363 * snarf.h (SCM_PROC1): Replaced SCM (*) (...) with
3364 SCM_FUNC_CAST_ARBITRARY_ARGS.
3366 Tue Jan 11 13:44:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3368 * guile-func-name-check.in: Added this script to statically check
3369 #define FUNC_NAME, #undef FUNC_NAME in the source.
3371 * sort.c, posix.c: Fix #undef FUNC_NAME lines to not have trailing
3372 redundant comment, semicolon; caught by new guile-func-name-check
3375 * debug.c: Fix mistaken #define FUNC_NAME for scm_make_iloc.
3376 Caught by new guile-func-name-check-script.
3378 * Makefile.am: Added guile-func-name-check to bin_SCRIPTS
3380 * ramap.c: Fix #if 0'd out code to be syntactically acceptable to
3381 guile-func-name-check.
3383 * guile-doc-snarf.in: Run guile-func-name-check on the file before
3386 Tue Jan 11 11:31:10 2000 Greg J. Badros <gjb@cs.washington.edu>
3388 * fports.c, ports.c, ports.h, strports.c, vports.c: Make write
3389 port function take const void*, not void*.
3391 Tue Jan 11 11:18:07 2000 Greg J. Badros <gjb@cs.washington.edu>
3393 * scm_validate.h, chars.c, ports.c, print.c, read.c, strings.c,
3394 strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
3395 SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
3396 consistency with the other macros dealing with immediate
3397 characters. (Similar to INT -> INUM change a week or so ago).
3399 Tue Jan 11 10:41:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3401 * dynl.c, error.c, eval.c, feature.c, filesys.c, fports.c, list.c, load.c,
3402 net_db.c, read.c, socket.c: Update error messages to use ~A for
3403 %s, ~S for %S to work with new `simple-format' format and be
3404 standardized better.
3406 * print.h, print.c (scm_simple_format): Added `simple-format'
3407 primitive. It's the old scm_display_error, with ARGS now a rest
3408 parameter, and the destination first instead of last (and a couple
3409 new capabilities inspired by `format' -- #t as destination means
3410 current-output-port, #f means return the formatted text as a
3413 * gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
3415 * backtrace.c (scm_display_error_message): Rewrote to use
3416 scm_simple_format() procedure.
3418 * __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
3420 2000-01-09 Marius Vollmer <mvo@zagadka.ping.de>
3422 Finally applied the libltdl patch from Thomas Tanner, with slight
3425 * DYNAMIC-LINKING: Removed because it is obsolete.
3426 * dynl.c: Use ANSI prototypes.
3427 (sysdep_dynl_link): Use lt_dlopenext instead of lt_dlopen.
3428 * scmconfig.h.in: Do not change, as it is automatically generated.
3430 1999-07-25 Thomas Tanner <tanner@ffii.org>
3432 * dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c: deleted
3434 * Makefile.am: likewise, add INCLTDL (libltdl headers) to
3435 INCLUDES, set dlpreopened files in LDFLAGS, link libguile
3437 * dynl.c: use libltdl if DYNAMIC_LINKING is enabled,
3438 * guile.c: register preloaded modules
3439 * scmconfig.h.in: remove obsolete symbols
3441 2000-01-09 Gary Houston <ghouston@arglist.com>
3443 * These changes should make it unnecessary to call tzset from
3444 Scheme after modifying the TZ environment variable, even if the
3445 system date facilities cache the value.
3446 * stime.c (setzone, scm_localtime): added comments.
3447 (tzset): don't define a noop tzset macro if HAVE_TZSET not defined.
3448 (setzone): don't call tzset.
3449 (restorezone): call tzset only if HAVE_TZSET is defined.
3450 (scm_tzset): don't define if HAVE_TZSET not defined. Change the
3451 doc string to indicate that this procedure isn't likely to do
3453 (scm_localtime, scm_strftime, scm_mktime): call tzset if
3454 LOCALTIME_CACHE is defined.
3456 2000-01-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3458 * posix.c (scm_sync): Return SCM_UNSPECIFIED.
3460 2000-01-09 Gary Houston <ghouston@arglist.com>
3462 * eval.c: define scm_unbound_variable_key ('unbound-variable).
3463 scm_lookupcar1: throw an error with key 'unbound-variable instead
3464 of 'misc-error when an unbound variable is encountered.
3466 * filesys.c (scm_mkdir, scm_rmdir, scm_getcwd, scm_select,
3467 scm_symlink, scm_readlink, scm_lstat),
3468 posix.c (scm_setpgid, scm_setsid, scm_ctermid, scm_tcgetpgrp,
3469 scm_tcsetpgrp, scm_uname, scm_setlocale, scm_mknod, scm_nice,
3471 simpos.c (scm_system),
3472 stime.c (scm_times, scm_strptime):
3473 move the HAVE_XXX feature tests out of the procedure bodies.
3474 don't use SCM_SYSMISSING.
3475 scm_validate.h (SCM_SYSMISSING): removed.
3476 error.h, error.c (scm_sysmissing): comment that this is deprecated.
3477 see ChangeLog entry for 1999-12-28.
3479 Sat Jan 8 19:52:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3481 * scm_validate.h (SCM_VALIDATE_BOOL_COPY): Fix typo.
3483 Sat Jan 8 17:06:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3485 * backtrace.c: Fix spelling typo in a comment.
3487 * snarf.h: Use new SCM_DOCS macro to encapsulate the non SCM_INIT
3488 text. Reformatted some of the expansions.
3490 Fri Jan 7 15:50:46 2000 Greg J. Badros <gjb@cs.washington.edu>
3492 * scm_validate.h (SCM_OUT_OF_RANGE): Use scm_out_of_range_pos to
3493 report the position of the argument.
3495 * error.h, error.c (scm_out_of_range_pos): Added this function to
3496 take extra "pos" argument, the position number of the errant
3499 * debug.c: Use SCM_OUT_OF_RANGE instead of scm_out_of_range.
3501 * snarf.h: Use SCM_HERE and SCM_INIT as names, not SCM_NOTSNARF
3502 and SCM_SNARFING. Also put the %%% in the SCM_INIT since Mikael
3503 prefers that and I'm reasonably indifferent.
3505 Fri Jan 7 15:03:32 2000 Greg J. Badros <gjb@cs.washington.edu>
3507 * snarf.h: Factor out differences between C++ and non-C++ into
3508 SCM_FUNC_CAST_ARBITRARY_ARGS macro. Modify all the snarf macro
3509 definitions to use SCM_NOTSNARF and SCM_SNARFING macros (like
3510 Mikael's macros, below, but changed names and SCM_SNARFING no
3511 longer expands to include %%% -- that must appear in the argument
3512 so that the token appears at the call-site as a reminder).
3514 2000-01-07 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3516 * snarf.h (SCM_INSITU, SCM_INIT): New snarf macros for use in user
3517 snarf macro definitions.
3519 2000-01-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3521 * chars.c (scm_integer_to_char): Use Greg's nice
3522 SCM_VALIDATE_INUM_RANGE macro for argument checking for closer
3525 Thu Jan 6 11:48:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3527 * *.c, snarf.h: Replace GUILE_PROC1 with SCM_DEFINE1 throughout.
3529 Thu Jan 6 11:22:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3531 * Makefile.am (ETAGS_ARGS): Switch to SCM_DEFINE, SCM_DEFINE1
3532 instead of GUILE_PROC.
3534 Thu Jan 6 11:21:49 2000 Greg J. Badros <gjb@cs.washington.edu>
3536 * alist.c: Do not report mismatch errors on some uses of `tmp' (do
3537 this by using SCM_ARG2 instead of `2' in the SCM_VALIDATE_CONS
3540 Thu Jan 6 09:54:33 2000 Dirk Herrmann <dirk@ida.ing.tu-bs.de> --gjb applied
3542 * scm_validate.h: Remove some redundant NIMP tests.
3544 * alist.c: minimize scope of the tmp variables, and initialize
3545 them when declared. The strange SCM_NIMP tests are replaced by
3546 SCM_CONSP tests that more closely reflect the intended semantics.
3547 However, we don't get a performance penalty here, because the
3548 SCM_CONSP test was performed by the ALISTCELL test anyway. * The
3549 extremely ugly use of ASRTGO macros was removed: The calls to
3550 ASRTGO were not encapsulated by "#ifndef SCM_RECKLESS", but got a
3551 label parameter that only exists when SCM_RECKLESS is not defined.
3552 This works, because ASRTGO itself is defined in a way that it only
3553 makes use of the label parameter if SCM_RECKLESS is not defined
3554 (shudder!). Does guile make at all use of the possibility to
3555 define SCM_RECKLESS? * Codesize is likely to be reduced, since
3556 instead of two calls to SCM_ASSERT performed by the ALISTCELL test
3557 we now only get one test.
3559 * list.c: Use SCM_NNULLP, not SCM_NIMP as appropriate. Also use
3560 SCM_NULLP instead of SCM_IMP. Drop use of "register" keyword on
3561 some variables in `list?'. Fix `reverse' and `reverse!'
3562 primitives to handle improper lists better.
3564 Wed Jan 5 11:24:53 2000 Greg J. Badros <gjb@cs.washington.edu>
3566 * *.[ch]: Whitespace changes -- added space after SCM_VALIDATE_*
3567 macros and SCM_DEFINE macros to match GNU coding standards.
3569 Wed Jan 5 11:04:24 2000 Greg J. Badros <gjb@cs.washington.edu>
3571 * *.[ch]: Replace GUILE_PROC w/ SCM_DEFINE.
3573 Wed Jan 5 10:59:06 2000 Greg J. Badros <gjb@cs.washington.edu>
3575 * *.[ch]: Replace SCM_VALIDATE_INT w/ SCM_VALIDATE_INUM for
3576 better consistency with the names of other SCM_VALIDATE_ macros
3577 and better conformance to guile naming policy.
3579 Wed Jan 5 10:50:39 2000 Greg J. Badros <gjb@cs.washington.edu>
3581 * ports.c (s_scm_close_all_ports_except): Use SCM_ARG1 in a
3582 SCM_VALIDATE instead of 1 to avoid a check on the argument (since
3583 it's not the actual name of the formal).
3585 * guile-snarf.awk.in: Do argument/number mismatch checking and
3586 print warnings in an Emacs compile-mode parseable format.
3588 * struct.c: Use SCM_ASSERT_RANGE instead of SCM_ASSERT w/
3589 SCM_OUTOFRANGE as 3rd argument.
3591 * random.c: Fix argument/number mismatch (that I introduced :-( ).
3593 * __scm.h: Do not #define SCM_ARG* when snarfing;
3594 lets us distinguish between 1 and SCM_ARG1 when snarfing as only
3595 the former (using the number) requires the argument to match the
3596 formal in the current argument snarfing check.
3598 * snarf.h: Give new definition of SCM_ASSERT when in
3599 snarfing mode to output a lexically-identifiable sequence that the
3600 guile-snarf.awk script uses to verify argument/position matching.
3602 * ramap.c: Remove extraneous #undef FUNC_NAME.
3604 Wed Jan 5 08:36:38 2000 Greg J. Badros <gjb@cs.washington.edu>
3606 * guile-doc-snarf.awk.in: Removed -- guile-snarf.awk.in is the
3607 current version of the same functionality; it writes the .x output
3608 to stdout instead of directly into the file.
3610 Wed Jan 5 08:15:04 2000 Greg J. Badros <gjb@cs.washington.edu>
3612 * unif.c, symbols.c, strings.c, stacks.c, random.c, print.c,
3613 posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
3614 redundant with the safer macros. Patch from Dirk Hermann applied
3615 by hand. Thanks Dirk!
3617 * scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
3620 * ramap.c: whitespace change.
3622 Tue Jan 4 14:21:35 2000 Greg J. Badros <gjb@cs.washington.edu>
3624 * options.c, objects.c, keywords.c, gc.c: Some redundant SCM_NIMP
3625 removals from Dirk Hermann.
3627 * alist.c: Rename formals to match the parameter names in the
3628 documentation, updates to documentation. Thanks Dirk Hermann!
3630 2000-01-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3632 * eval.c (SCM_CEVAL): Reverse order of
3633 scm_stack_checking_enabled_p and SCM_STACK_OVERFLOW_P
3634 (Thanks to Brad Knotwell.)
3636 Mon Jan 3 08:30:02 2000 Greg Harvey <Greg.Harvey@thezone.net> (applied --01/03/00 gjb)
3638 * gc.c (scm_debug_newcell): Added SCM_SETCAR of the newly
3641 * pairs.h: Added a comment about the need for the SCM_SETCAR in
3644 Mon Jan 3 08:25:19 2000 Greg J. Badros <gjb@cs.washington.edu>
3646 * dynl-vms.c, debug.c, coop-threads.c, backtrace.c, eval.c: More
3647 SCM_NIMP tests that were redundant are now eliminated. Patches
3648 from Dirk Hermann applied by hand.
